Epidemiology and factors associated with the severity of viral acute lower respiratory infection in children hospitalized in Manaus,Amazonas, in 2017–2018: An observational study

To investigate the epidemiology and factors associated with the severity of viral acute lower respiratory infection (ALRI) in children hospitalized in Manaus, Amazonas, in 2017 to 2018.Retrospective cohort study of children hospitalized at the Hospital and Emergency Room Delphina Rinaldi Abdel Aziz, in Manaus, from April 01, 2017 to August 31, 2018, with a clinical diagnosis of ALRI and nasopharyngeal aspirates positive for at least 1 respiratory virus.One hundred forty-six children aged 0.2 to 66 months (median 7 months) were included. Patients were divided into 2 groups according to the disease severity classified by an adapted Walsh et al score: moderate disease, score 0–4, n = 66 (45.2%) and severe disease, score 5–7, n = 80 (54.8%). A greater number of viral ALRI cases were observed in the rainiest months. Respiratory syncytial virus was the most prevalent (n = 103, 70.3%), followed by metapneumovirus (n = 24, 16.4%), influenza virus (n = 17, 11.6%), parainfluenza virus (n = 11, 7.5%), and adenovirus (n = 4, 2.7%). Co-detections of 2 to 3 viruses were found in 12 (8.2%) patients. The presence of viral coinfection was an independent risk factor for disease severity (adjusted relative risk [RR] 1.53; 95% CI 1.10–2.14). Twelve patients (8.2%) died, all with severe disease. Risk factors for death were shock (adjusted RR 10.09; 95% CI 2.31–43.90) and need for vasoactive drugs (adjusted RR 10.63; 95% CI 2.44–46.31).There was a higher incidence of viral ALRI in Manaus in the rainy season. Respiratory syncytial virus was the most prevalent virus. The presence of viral coinfection was an independent risk factor for disease severity.     

Prognostic factors for overall survival in patients with clear cell metastatic renal cell carcinoma: Model development and external validation with Memorial Sloan Kettering Cancer Center model and the international metastatic renal cell carcinoma database consortium model

To develop a new prognostic model for the overall survival of patients with clear cell metastatic renal cell carcinoma (mRCC) using Korean Renal Cancer Study Group (KRoCS) database and compared it with 2 renowned prognostic models: the Memorial Sloan Kettering Cancer Center (MSKCC) and the international metastatic renal cell carcinoma database consortium (IMDC) models.Data of 790 patients diagnosed with mRCC and receiving targeted therapy as their first-line treatment were pooled to this study. Data from 4 hospitals (n = 619) were used to develop the new model and those from other 5 hospitals (n = 171) were used for external validation. After detecting prognostic factors in multivariable Cox proportional-hazards regression analysis, patients were classified into 3 risk groups, favorable (0), intermediate (1–2), and poor (3 and more) by the number of prognostic factors.Seven variables such as more than 2 metastasis sites, no prior nephrectomy, Eastern Cooperative Oncology Group performance status ≥2, low hemoglobin, high serum corrected calcium, high neutrophil, high serum alkaline phosphatase were identified as prognostic factors for poor overall survival. Also, risk groups were categorized into 3 groups; median overall survival was 61.1 months in favorable, 26.5 months in intermediate, and 6.8 months in poor group. KRoCS ranked the first in all 3 statistical parameters including akaike information criterion (AIC), concordance index and generalized R² among other prognostic models.We developed the KRoCS model and validated it externally with demonstrating its superiority over MSKCC and IMDC models. The KRoCS model can provide useful information for counseling patients with clear cell mRCC regarding life-expectancy.     

Single-center experience on actual mid-term (≥5 years) and long-term (≥10 years) survival outcome in patients with hepatocellular carcinoma after curative hepatectomy: A bimodal distribution

Analysis for actual mid-term (≥5 years) and long-term (≥10 years) survivors with hepatocellular carcinoma (HCC) following curative hepatectomy are rarely reported in the literature.This retrospective study aims to study the mid- and long-term survival outcome and associated prognostic factors following curative hepatectomy for HCC in a tertiary referral center.The clinical data of 325 patients who underwent curative hepatectomy for HCC were reviewed. They were stratified into 3 groups for comparison (Group 1, overall survival <5 years; Group 2, overall survival ≥5, and <10 years; Group 3, overall survival ≥10 years). Favorable independent prognostic factors for mid- and long-term survival were analyzed.A bimodal distribution of actual survival outcome was observed, with short-term (<5 years) survival of 52.7% (n = 171), mid-term survival of 18.1% (n = 59), and long-term survival of 29.2% (n = 95). Absence of microvascular invasion (OR 3.690, 95% CI: 1.562–8.695) was independent good prognostic factor for mid-term survival. Regarding long-term overall survival, young age (OR 1.050, 95% CI: 0.920–0.986), ASA grade ≤2 (OR 3.746, 95% CI: 1.325–10.587), high albumin level (OR 1.008, 95% CI: 0.920–0.986), solitary tumor (OR 3.289, 95% CI: 1.149–7.625) and absence of microvascular invasion (OR 4.926, 95% CI: 2.192–11.111) were independent good prognostic factors.Curative hepatectomy results in bimodal actual survival outcome with favorable long-term survival rate of 29.2%. Favorable independent prognostic factors (age, ASA grade, albumin level, tumor number, and microvascular invasion) are identified for overall survival.     

Prognostic value of targeted temperature management on outcomes of hanging-induced out-of-hospital cardiac arrest: A nationwide observational study

This study aimed to evaluate the prognostic significance of targeted temperature management (TTM) on hanging-induced out-of-hospital cardiac arrest (OHCA) patients using nationwide data of South Korea.Adult hanging-induced OHCA patients from 2008 to 2018 were included in this nationwide observational study. Patients who assigned into 2 groups based on whether they did (TTM group) or did not (non-TTM group) receive TTM. Outcome measures included survival to hospital discharge and a good neurological outcome at hospital discharge.Among the 293,852 OHCA patients, 3545 patients (non-TTM, n = 2762; TTM, n = 783) were investigated. After propensity score matching for all patients, 783 matched pairs were available for analysis. We observed no significant inter-group differences in the survival to hospital discharge (non-TTM, n = 27 [3.4%] vs TTM, n = 23 [2.9%], P = .666) or good neurological outcomes (non-TTM, n = 23 [2.9%] vs TTM, n = 14 [1.8%], P = .183). In the multivariate analysis, prehospital return of spontaneous circulation (odds ratio [OR], 22.849; 95% confidence interval [CI], 11.479–45.481, P < .001) was associated with an increase in survival to hospital discharge, and age (OR, 0.971; 95% CI, 0.944–0.998, P = .035), heart disease (OR, 16.875; 95% CI, 3.028–94.036, P = .001), and prehospital return of spontaneous circulation (OR, 133.251; 95% CI, 30.512–581.930, P < .001) were significant prognostic factors of good neurological outcome. However, TTM showed no significant association with either outcome.There were no significant differences in the survival to hospital discharge and good neurological outcomes between non-TTM and TTM groups of hanging-induced OHCA patients.     

Somatostatin Receptor SSTR-2a Expression Is a Stronger Predictor for Survival Than Ki-67 in Pancreatic Neuroendocrine Tumors

Somatostatin receptors (SSTR) are commonly expressed by neuroendocrine tumors. Expression of SSTR-2a and SSTR-5 may impact symptomatic management; however, the impact on survival is unclear. The aim of this study is to correlate SSTR-2a and SSTR-5 expression in pancreatic neuroendocrine tumors (PNETs) with survival.This study is designed to determine the prognostic significance of somatostatin receptors SSTR-2a and SSTR-5 in PNETs.This retrospective cohort study included cases of resected PNETs between 1992 and 2014. Clinical data, histopathology, expression of SSTR and Ki-67 by immunohistochemistry, and long-term survival were analyzed.A total of 99 cases were included in this study. The mean age was 57.8 years (18–87 years) and median tumor size was 25 mm (range 8–160 mm). SSTR-2a and SSTR-5 expression was scored as negative (n = 19, 19.2%; n = 75, 75.8%, respectively) and positive (n = 80, 80.1%; n = 24, 24.2%). The median follow-up was 49 months. SSTR-2a expression was associated with improved overall survival, with cumulative survival rates at 1, 3, and 5 years being 97.5%, 91.5%, and 82.9%, respectively. Univariate analysis demonstrated better survival in SSTR-2a positive patients (log rank P = 0.04). SSTR-5 expression was not associated with survival outcomes (log rank P = 0.94). Multivariate analysis showed that positive SSTR-2a expression is a stronger prognostic indicator for overall survival [Hazard Ratio (HR): 0.2, 95% Confidence interval (CI): 0.1–0.8] compared to high Ki-67 (HR: 0.8, 95% CI: 0.1–5.7).Expression of SSTR-2a is an independent positive prognostic factor for survival in PNETs.     

Immune checkpoint inhibitors in patients with solid tumors and poor performance status: A prospective data from the real-world settings

Immune checkpoint inhibitors (ICIs) are rapidly being incorporated as treatment option either alone or in combination with chemotherapy in most of the solid tumors. Since there is very limited data of ICI in patients with poor performance status (PS) from the real world settings, we performed a retrospective audit of patients who received ICI and report the analysis based on ECOG PS of these patients.This study is a retrospective audit of a prospectively collected database of patients receiving ICIs for advanced solid tumors in any line between August 2015 and November 2018 at Tata Memorial Hospital, Mumbai, India. All statistical calculations were performed using SPSS statistical software for windows version 20.0.A total of 155 patients who received ICIs during the specified period were evaluated for this study. Baseline ECOG PS 0–1 (n = 103, 66.4%) patients was associated with median OS 9.1 (95% CI [confidence interval], 4.4-NR) months when compared to ECOG 2–4 (n = 52, 33.5%) which had a median OS of 2.9 (95% CI; 1.8–5.5) months (HR, 1.7, 95% CI, 1.1–2.7, log rank P = .017). The disease control rate for the poor PS group was 34.6%. However, 27.3% patients (95% CI: 20.3–34.3) were still alive at 1 year. Median OS in patients with PS 2 was 3.7 months (95% CI: 0–11.6) as compared to 1.8 months (95% CI: 0.2–3.4) for those with PS 3–4 (HR-2.0; 95% CI: 1.0–3.9, P = .041). The tolerance to ICIs was good with no grade 3/4 toxicities in 44 (84.6%) patients.Immune checkpoint inhibitors are a safe and effective therapeutic option even in solid tumor patients with poor performance status.     

Follow-up care over 12 months of patients with prostate cancer in Spain: A multicenter prospective cohort study

The therapeutic approach is crucial to prostate cancer prognosis. We describe treatments and outcomes for a Spanish cohort of patients with prostate cancer during the first 12 months after diagnosis and identify the factors that influenced the treatment they received.This multicenter prospective cohort study included patients with prostate cancer followed up for 12 months after diagnosis. Treatment was stratified by factors such as hospital, age group (<70 and ≥70 years), and D’Amico cancer risk classification. The outcomes were Eastern Cooperative Oncology Group (ECOG) performance status, adverse events (AEs), and mortality. The patient characteristics associated with the different treatment modalities were analyzed using multivariate logistic regression.We included 470 men from 7 Spanish tertiary hospitals (mean (standard deviation) age 67.8 (7.6) years), 373 (79.4%) of which received treatment (alone or in combination) as follows: surgery (n = 163; 34.7%); radiotherapy (RT) (n = 149; 31.7%); and hormone therapy (HT) (n = 142; 30.2%). The remaining patients (n = 97) were allocated to no treatment, that is, watchful waiting (14.0%) or active surveillance (5.7%). HT was the most frequently administered treatment during follow-up and RT plus HT was the most common therapeutic combination. Surgery was more frequent in patients aged <70, with lower histologic tumor grades, Gleason scores <7, and lower prostate-specific antigen levels; while RT was more frequent in patients aged ≥70 with histologic tumor grade 4, and higher ECOG scores. HT was more frequent in patients aged ≥70, with histologic tumor grades 3 to 4, Gleason score ≥8, ECOG ≥1, and higher prostate-specific antigen levels. The number of fully active patients (ECOG score 0) decreased significantly during follow-up, from 75.3% at diagnosis to 65.1% at 12 months (P < .001); 230 (48.9%) patients had at least 1 AE, and 12 (2.6%) patients died.Surgery or RT were the main curative options. A fifth of the patients received no treatment. Palliative HT was more frequently administered to older patients with higher tumor grades and higher Gleason scores. Close to half of the patients experienced an AE related to their treatment.     

An Ultra-Deep Targeted Sequencing Gene Panel Improves the Prognostic Stratification of Patients With Advanced Oral Cavity Squamous Cell Carcinoma

An improved prognostic stratification of patients with oral cavity squamous cell carcinoma (OSCC) and pathologically positive (pN+) nodes is urgently needed. Here, we sought to examine whether an ultra-deep targeted sequencing (UDT-Seq) gene panel may improve the prognostic stratification in this patient group.A mutation-based signature affecting 10 genes (including genetic mutations in 6 oncogenes and 4 tumor suppressor genes) was devised to predict disease-free survival (DFS) in 345 primary tumor specimens obtained from pN+ OSCC patients. Of the 345 patients, 144 were extracapsular spread (ECS)-negative and 201 were ECS-positive. The 5-year locoregional control, distant metastases, disease-free, disease-specific, and overall survival (OS) rates served as outcome measures.The UDT-Seq panel was an independent risk factor (RF) for 5-year locoregional control (P = 0.0067), distant metastases (P = 0.0001), DFS (P < 0.0001), disease-specific survival (DSS, P < 0.0001), and OS (P = 0.0003) in pN+ OSCC patients. The presence of ECS and pT3–4 disease were also independent RFs for DFS, DSS, and OS. A prognostic scoring system was formulated by summing up the significant covariates (UDT-Seq, ECS, pT3–4) separately for each survival endpoint. The presence of a positive UDT-Seq panel (n = 77) significantly improved risk stratification for all the survival endpoints as compared with traditional AJCC staging (P < 0.0001). Among ECS-negative patients, those with a UDT-Seq-positive panel (n = 31) had significantly worse DFS (P = 0.0005) and DSS (P = 0.0002). Among ECS-positive patients, those with a UDT-Seq-positive panel (n = 46) also had significantly worse DFS (P = 0.0032) and DSS (P = 0.0098).Our UDT-Seq gene panel consisting of clinically actionable genes was significantly associated with patient outcomes and provided better prognostic stratification than traditional AJCC staging. It was also able to predict prognosis in OSCC patients regardless of ECS presence.     

Human Papillomavirus Infections are Common and Predict Mortality in a Retrospective Cohort Study of Taiwanese Patients With Oral Cavity Cancer

Human papillomavirus (HPV) infections are deemed to play a role in the pathogenesis of oral cavity cancer (OCC). However, their exact prevalence and clinical significance remain unclear. Herein, we investigated the prevalence and prognostic value of HPV infections in a large sample of Taiwanese OCC patients.This study was designed as a retrospective cohort study. Between 2004 and 2011, we identified 1002 consecutive patients with newly diagnosed OCC who were scheduled for standard treatment. HPV genotyping was performed in tumor specimens using polymerase chain reaction-based HPV blots. To investigate the temporal trends of HPV infections and their impact on 5-year overall survival (OS), patients were divided into 2 cohorts according to calendar periods: “2004 cohort” (2004–2007; n = 466) and “2008 cohort” (2008–2011; n = 536). Univariate and multivariate Cox regression models were also used to identify the independent predictors of OS in the 2 cohorts. A weighted risk score was assigned to each factor based on the range of their corresponding hazard ratios and validated in both cohorts using the c-statistic.The overall prevalence of HPV infections was 19%, with a trend toward decreasing rates from 2004 to 2011. In patients without risky oral habits, the 5-year OS rate of HPV-positive patients was significantly lower than that of HPV-negative cases (49% vs 80%; P = 0.021). In the 2004 cohort, multivariate analysis identified HPV16, pathological T3/T4, pathological N1/N2, and extracapsular spread as independent adverse prognostic factors for OS. In the 2008 cohort, pathological N1/N2, pathological stage III/IV, and histological tumor depth >8 mm were identified as independent adverse prognostic factors. Using a weighted grading system incorporating HPV16 infection, we devised a prognostic index that identified 4 distinct risk categories with 5-year OS rates ranging from 25% to 89% (c-statistic = 0.76) in the 2004 cohort. The validity of the index was internally confirmed in the 2008 cohort (c-statistic = 0.71).We conclude that HPV infections are common in Taiwanese OCC patients and predict 5-year OS. If independently validated, our composite prognostic score comprising HPV16 infection may be useful for allocating OCC patients to risk-adapted therapies.     

Prognostic factors of patients after liver cancer surgery: Based on Surveillance,Epidemiology, and End Results database

This study aimed to investigate the prognostic factors of patients after liver cancer surgery and evaluate the predictive power of nomogram. Liver cancer patients with the history of surgery in the Surveillance, Epidemiology, and End Results database between 2000 and 2016 were preliminary retrieved. Patients were divided into the survival group (n = 2120, survival ≥5 years) and the death group (n = 2615, survival < 5 years). Single-factor and multi-factor Cox regression were used for analyzing the risk factors of death in patients with liver cancer after surgery. Compared with single patients, married status was the protective factor for death in patients undergoing liver cancer surgery (HR = 0.757, 95%CI: 0.685–0.837, P < .001); the risk of death in Afro-Americans (HR = 1.300, 95%CI: 1.166–1.449, P < .001) was higher than that in Caucasians, while the occurrence of death in Asians (HR = 0.821, 95%CI: 0.1754–0.895, P < .0012) was lower; female patients had a lower incidence of death (HR = 0.875, 95%CI: 0.809–0.947, P < .001); grade II (HR = 1.167, 95%CI: 1.080–1.262, P < .001), III (HR = 1.580, 95%CI: 1.433–1.744, P < .001), and IV (HR = 1.419, 95%CI: 1.145–1.758, P = 0.001) were the risk factors for death in patients with liver cancer. The prognostic factors of liver cancer patients after surgery include the marital status, race, gender, age, grade of cancer and tumor size. The nomogram with good predictive ability can provide the prediction of 5-year survival for clinical development.     

Use of traditional Chinese medicine as an adjunctive treatment for COVID-19: A systematic review and meta-analysis

Background:This review aims to evaluate the supportive effects of frequently used traditional Chinese medicine (TCM) for the treatment of coronavirus disease 2019 (COVID-19).Methods:Five databases were searched through July 7, 2020. Randomized controlled trials investigating the efficacy of TCM for use in the treatment of COVID-19 were included. Newcastle–Ottawa Scale (NOS) and modified Jadad score were used for the evaluation of the methodological quality of the included studies. Weighted mean difference, odds ratio (OR), and 95% confidence interval (95% CI) were calculated for pooling out results. Data were extracted for conducting a meta-analysis using STATA version 12.0.Results:Eight studies with a total of 750 patients were included in this meta-analysis. All included trial groups involved treatment with TCM and Western medicine, while the control groups were treated only with Western medicine. The intervention therapy significantly improved the overall effective rate (n = 346, OR = 2.5, 95% CIs = 1.46–4.29), fever symptom disappearance rate (n = 436; OR = 3.6; 95% CIs = 2.13–6.08), fatigue symptom disappearance rate (n = 436; OR = 3.04; 95% CIs = 1.76–5.26), cough symptom disappearance rate (n = 436; OR = 2.91; 95% CIs = 1.36–6.19), and sputum production reduction (n = 436; OR = 5.51; 95% CIs = 1.94–15.64). Based on the Newcastle–Ottawa Scale assessment, 6 studies received a score of 4, and 1 study achieved a score of 5. One study was assessed using the modified Jadad score, achieving a score of 6.Conclusions:The integration of TCM with Western medicine has significantly improved the treatment for COVID-19 patients compared to Western medicine treatment alone. Combined therapy using TCM and Western medicine revealed the potential adjunctive role of TCM in treating COVID-19. However, high-quality clinical studies are still required to further evaluate the efficacy and safety of TCM in the treatment of COVID-19.     

Case reports of robot-assisted laparoscopic radical nephrectomy and inferior vena cava tumor thrombectomy: A retrospective analysis

Renal cell carcinoma is one common type of urologic cancers. It has tendencies to invade into the inferior vena cava (IVC) and usually requires an open surgery procedure. High rates of operative complications and mortality are usually associated with an open surgery procedure. The recently emerged robot-assisted laparoscopic radical nephrectomy (RAL-RN) and IVC tumor thrombectomy have shown to reduce operative related complications in patients with renal cell carcinoma.This case series study aimed to summarize technical utilization, perioperative outcomes, and efficacies of RAL-RN and IVC tumor thrombectomy in our hospital. A retrospective analysis was performed on clinical data from 20 patients who underwent RAL-RN and IVC tumor thrombectomy from January 2017 to December 2019 in our department.Patients had a median age of 59 years (interquartile range [IQR], 46–68). Four patients had renal neoplasm on left side and 16 on right side. Nineteen patients underwent RAL-RN (level 0: n = 2) or RAL-RN with IVC thrombectomy (n = 17) (level I: n = 3; level II: n = 12; and level III: n = 3) and 1 patient was converted into an open surgery. The median operative time was 328 minutes (IQR, 221–453). The estimated median blood loss was 500 mL (IQR, 200–1200). The median size of removed renal carcinoma was 67 cm² (IQR, 40–91); the length of IVC tumor thrombus was 5 cm (IQR, 3–7). The postsurgery hospital length of stay was 6 days (IQR, 5–7). The complications included intestinal obstruction (n = 1), lymphatic fistula (n = 1), heart failure (n = 1), and low hemoglobin level (n = 1). The outcomes for patients after 16 months (IQR, 11–21) follow-up were tumor-free (n = 10), tumor progression (n = 4), loss of contact (n = 1), and death (n = 5).We concluded that RAL-RN and IVC thrombectomy renders good safety profiles including minimal invasiveness, low estimated median blood loss, short hospitalization, low morbidity, and quick renal function recovery. The long-term efficacy needs a further investigation.     

Risk factors for postoperative pneumonia and prognosis in lung cancer patients after surgery: A retrospective study

Postoperative pneumonia (POP) is one of the most frequent complications following lung surgery. The aim of this study was to identify the risk factors for developing POP and the prognostic factors in lung cancer patients after lung resection.We performed a retrospective review of 726 patients who underwent surgery for stages I–III lung cancer at a single institution between August 2017 and July 2018 by conducting logistic regression analysis of the risk factors for POP. The Cox risk model was used to analyze the factors influencing the survival of patients with lung cancer.We identified 112 patients with POP. Important risk factors for POP included smoking (odds ratio [OR], 2.672; 95% confidence interval [CI], 1.586–4.503; P < .001), diffusing capacity for carbon monoxide (DLCO) (40–59 vs ≥80%, 4.328; 95% CI, 1.976–9.481; P < .001, <40 vs ≥80%, 4.725; 95% CI, 1.352–16.514; P = .015), and the acute physiology and chronic health evaluation (APACHE) II score (OR, 2.304; 95% CI, 1.382–3.842; P = .001). In the Cox risk model, we observed that age (hazard ratios (HR), 1.633; 95% CI, 1.062–2.513; P = .026), smoking (HR, 1.670; 95% CI, 1.027–2.716; P = .039), POP (HR, 1.637; 95% CI, 1.030–2.600; P = .037), etc were predictor variables for patient survival among the factors examined in this study.The risk factors for POP and the predictive factors affecting overall survival (OS) should be taken into account for effective management of patients with lung cancer undergoing surgery.     

Combined immune score predicts the prognosis of newly diagnosed multiple myeloma patients in the bortezomib-based therapy era

To investigate the effect of a combined immune score including the lymphocyte-to-monocyte ratio (LMR) and uninvolved immunoglobulin (u-Ig) levels on the prognosis of newly diagnosed multiple myeloma (NDMM) patients treated with bortezomib.Clinical data of 201 NDMM patients were retrospectively analyzed. Patients with LMR ≥ 3.6 and LMR < 3.6 were scored 0 and 1, respectively. Patients with preserved u-Ig levels, suppression of 1 u-Ig, and suppression of at least 2 u-Igs were scored 0, 1, and 2, respectively. The immune score, established from these individual scores, was used to separate patients into good (0–1 points), intermediate (2 points), and poor (3 points) risk groups. The baseline data, objective remission rate (ORR), whether receive maintenance treatment regularly and overall survival of patients before treatment were analyzed.The ORR of the good-risk group was significantly higher than that of the intermediate-risk group (75.6% vs 57.7%, P = .044) and the poor-risk group (75.6% vs 48.2%, P = .007). The multivariate analysis results showed that age ≥ 65 years, International Staging System stage III, platelet count ≤ 100 × 109/L, lactate dehydrogenase (LDH) > 250 U/L, serum calcium > 2.75 mmol/L, no receipt of regular maintenance treatment, LMR < 3.6, suppressed u-Igs = 1, suppressed u-Igs ≥ 2, intermediate-risk group and poor-risk group were independent predictors of poor overall survival.In the bortezomib era, the LMR, u-Ig levels, and the immune score play an important role in the prognosis of NDMM patients. Among them, the immune score showed the strongest prognostic value, and it could be a beneficial supplement for the early identification of high-risk patients.     

Gastric Carcinomas in Young (Younger than 40 Years) Chinese Patients: Clinicopathology,Family History,and Postresection Survival

Little is known about clinicopathological characteristics of gastric carcinoma (GC) in young (≤40 years) Chinese patients. We aimed in this study to analyze those features along with family history and prognostic factors after resection.We retrospectively reviewed all 4671 GC resections (surgical and endoscopic) performed at our center from 2004 to 2014 and identified 152 (3.2%) consecutive young patients. Patient demographics, clinical results, family history, and endoscopic-pathological findings were analyzed along with the older (>41 years) GC controls recruited in the same study period. Clinicopathological factors related to postresection outcomes were assessed statistically.The trend of GC resections in young patients was not changed over the study period. Compared to old GCs, the young GC cohort was predominant in women, positive family history, middle gastric location, the diffuse histology type, shorter duration of symptoms, and advanced stage (pIII+pIV, 53.3%). Radical resection was carried out in 90.1% (n = 137) with a better 5-year survival rate (70.3%) than palliative surgery (0%, n = 15). There was no significant difference in clinicopathological characteristics between familial GC (FGC, n = 38) and sporadic GC (SGC, n = 114) groups. Very young patients (≤ 30 years, n = 38) showed lower Helicobacter pylori (Hp) infection and significantly higher perineural invasion rates, compared to older (31–40 years) patients. Hp infection was more commonly seen in the Lauren''s intestinal type and early pT stages (T1+T2). Independent prognostic factors for worse outcomes included higher serum CA 72–4, CA 125 levels, positive resection margin, and stage pIII–pIV tumors. The 5-year survival rate was significantly higher in patients with radical resection than those without.GCs in young Chinese patients were prevalent in women with advanced stages but showed no significant differences in clinicopathology between FGC and SGC groups. High serum CA 72–4 and CA 125 levels may help identify patients with worse outcomes. Radical resection improved postresection survival.     

Comparison of 10 noninvasive models for predicting overall survival in patients with intermediate-stage hepatocellular carcinoma

Intermediate-stage hepatocellular carcinoma (HCC) is heterogeneous in terms of tumor size, number, and effects on liver function. Various noninvasive models have been proposed to assess functional hepatic reserve or fibrosis severity in patients with HCC. This study assessed the feasibility of 10 noninvasive models and compared their prognostic ability for patients with intermediate-stage HCC.This study retrospectively enrolled 493 patients with intermediate-stage HCC who received treatment at China Medical University Hospital from January 2012 to November 2018. Demographic data, clinical features, and factors associated with overall survival (OS) were recorded at baseline. Receiver-operating characteristic curve analysis and the DeLong method were respectively employed to evaluate and compare the models’ OS prediction performance.Of the 493 patients, 373 (75.7%) were male, and 275 (55.8%) had liver cirrhosis (LC). The median age was 64 years (interquartile range: 55–72). Most patients had tumor volume ≤50% (n = 424, 86.0%), and the maximum tumor size was 6.0 (4.0–8.5) cm. The median α-fetoprotein was 36.25 (6.13–552.91) ng/mL. The patients underwent transarterial chemoembolization (TACE, n = 349) or surgery (n = 144). The median follow-up period was 26.07 (9.77–48.27) months. Across the 10 models, the albumin–bilirubin (ALBI) score had the highest area under the receiver operating characteristic curve (AUROC) (0.644, 95% confidence interval: 0.595–0.693) in all patients. In subgroup analyses, the Lok index, platelet–albumin–bilirubin score, ALBI score, and Lok index had the highest AUROC values in patients without cirrhosis, with cirrhosis, undergoing TACE, and undergoing surgery, respectively. Multivariate Cox regression analysis revealed that independent predictors of longer OS were ALBI grade 1 in all patients, patients with LC, and patients undergoing TACE and Lok index grade 1 in patients without LC and patients undergoing surgery.Among the 10 noninvasive models, ALBI score exhibited the highest diagnostic value in predicting OS for all patients, patients with cirrhosis, and those undergoing TACE, and Lok index grade exhibited the highest diagnostic value in predicting OS in patients without cirrhosis and those undergoing surgery.     

Simple prognostic markers for optimal treatment of patients with unresectable pancreatic cancer

Most patients with pancreatic cancer are ineligible for curative resection at diagnosis, resulting in poor prognosis. This study aimed to evaluate the prognostic factors in patients with unresectable pancreatic cancer.We retrospectively collected clinical data from 196 patients with unresectable pancreatic cancer who received palliative chemotherapy (N = 153) or palliative care alone (N = 43) from January 2011 to December 2013. Patients’ background data and overall survival were analyzed using the Cox proportional hazard regression model.In patients receiving palliative chemotherapy (gemcitabine-based regimen, 88.2%) and palliative care alone, the median (range) ages were 68 (43–91) and 78 (53–90) years, and metastatic diseases were present in 80% (N = 123) and 86% (N = 37), respectively. Multivariate analysis in the palliative chemotherapy patients showed that liver metastasis (hazard ratio [HR] 2.25, 95% confidence interval [CI] 1.58–3.20, P < .001), neutrophil-to-lymphocyte ratio (>4.5 vs ≤4.5; HR 3.45, 95% CI 2.22–5.36, P < .001), and cancer antigen 19-9 (CA19-9) (≥900 vs <900 U/mL; HR 1.45, 95% CI 1.02–2.05, P = .036) were independent prognostic factors. In those receiving palliative care alone, lung (HR 3.27, 95% Cl 1.46-7.35, p = 0.004) and peritoneum (HR 2.50, 95% CI 1.20–5.18, P = .014) metastases and the C-reactive protein-to-albumin ratio (≥1.3 vs <1.3; HR 3.33, 95% Cl 1.51–7.35, P = .003) were independent prognostic factors. Furthermore, patients with multiple factors had worse prognosis in both groups. Median survival time of palliative chemotherapy patients with risk factors 0, 1, 2, and 3 were 13.1 (95% CI 8.0–16.9), 9.4 (95% CI 7.9–10.1), 6.6 (95% CI 4.9–7.8), and 2.5 (95% CI 1.7–4.0) months, respectively. Similarly, median survival time was 5.7 (95% CI 1.3 -8.0), 2.1 (95% CI 1.5–3.9), and 1.3 (95% CI 0.6–1.7) months, respectively, for palliative care alone patients with risk factor 0, 1, and 2 to 3.Prognostic markers for pancreatic cancer were neutrophil-to-lymphocyte ratio, liver metastasis, and CA19-9 in patients undergoing palliative chemotherapy and C-reactive protein-to-albumin ratio and lung/peritoneum metastases in patients undergoing palliative care alone. These simple markers should be considered when explaining the prognosis and therapeutic options to patients.     

Establishment and Validation of ALPH-Q Score to Predict Mortality Risk in Patients With Acute-on-Chronic Hepatitis B Liver Failure: A Prospective Cohort Study

Currently, there are no robust models for predicting the outcome of acute-on-chronic hepatitis B liver failure (ACHBLF). We aimed to establish and validate a new prognostic scoring system, named ALPH-Q, that integrates electrocardiography parameters that may be used to predict short-term mortality of patients with ACHBLF.Two hundred fourteen patients were included in this study. The APLH-Q score was constructed by Cox proportional hazard regression analysis and was validated in an independent patient cohort. The area under the receiver-operating characteristic curve was used to compare the performance of different models, including APLH-Q, Child–Pugh score (CPS), model of end-stage liver disease (MELD), and a previously reported logistic regression model (LRM).The APLH-Q score was constructed with 5 independent risk factors, including age (HR = 1.034, 95% CI: 1.007–1.061), liver cirrhosis (HR = 2.753, 95% CI: 1.366–5.548), prothrombin time (HR = 1.031, 95% CI: 1.002–1.062), hepatic encephalopathy (HR = 2.703, 95% CI: 1.630–4.480), and QTc (HR = 1.008, 95% CI: 1.001–1.016). The performance of the ALPH-Q score was significantly better than that of MELD and CPS in both the training (0.896 vs 0.712, 0.896 vs 0.738, respectively, both P < 0.05) and validation cohorts (0.837 vs 0.689, 0.837 vs 0.585, respectively, both P < 0.05). Compared with LRM, APLH-Q also showed a better performance (0.896 vs 0.825, 0.837 vs 0.818, respectively).We have developed a novel APLH-Q score with greater performance than CPS, MELD, and LRM for predicting short-term mortality of patients with ACHBLF.     

The Effectiveness of ART Score in Selecting Patients for Transarterial Chemoembolization Retreatment: A Cohort Study in Taiwan

The major issue in selecting patients for transarterial chemoembolization (TACE) lies in determining the optimal number of TACE sessions that may benefit patients before switching to other therapies. This is often a subjective decision not based on any standardized protocol. The ART (Assessment for Retreatment with Transarterial chemoembolization) score was recently developed to determine patients who may benefit from multiple sessions of TACE for treatment of hepatocellular carcinoma. The primary aim of the study was to validate the ART score in a Taiwanese cohort. The secondary aims were to evaluate overall survival and clinical determinants of improved survival in patients treated with multiple TACE sessions. The ART score, clinical characteristics, and outcomes of 82 patients with hepatocellular carcinoma who received multiple TACE sessions at Taipei Veterans General Hospital from September 2007 to July 2013 were analyzed. Among the 82 patients evaluated, 69.5% (n = 57) had an ART score of 0 to 1.5 and 34.1% (n = 25) had a score of ≥2.5. The median overall survival was 23.1 months and the overall mortality rate was 62.2% (n = 51). The ART score was not associated with survival (P = 0.58). Multivariate Cox regression analysis revealed that tumor size >7.2 cm (hazard ratio 4.44, P < 0.001), aspartate transaminase (AST) level above 95 IU/L (hazard ratio 2.18, P = 0.02), AST increase more than 25% (hazard ratio 2.13, P = 0.02), 2nd/1st (pre-TACE) alpha-fetoprotein ratio (hazard ratio 1.40, P = 0.001), and lack of radiological response to TACE (hazard ratio 2.21, P = 0.02) were independent clinical determinants of survival. The ART score was not found to be effective in selecting patients for TACE retreatment in our Taiwanese cohort. Large tumor size, high AST level, high 2nd/1st (pre-TACE) alpha-fetoprotein ratio, AST increase >25%, and lack of radiological response to TACE were independently associated with shorter survival after TACE therapy.     

High Expression of MicroRNA-196a Indicates Poor Prognosis in Resected Pancreatic Neuroendocrine Tumor

There is limited data on miRNA expression in pancreatic neuroendocrine tumors (PanNETs). In this study, we aimed to identify miRNAs that could be potential prognostic biomarkers of PanNETs in patients who underwent curative surgery.For miRNA target screening, 2 primary PanNETs and corresponding liver metastases were screened for miRNA expression by the NanoString nCounter analysis. Candidate miRNAs were selected by ≥2-fold difference of expression between metastatic versus primary tumor. For miRNA target validation, quantitative real-time PCR was performed for candidate miRNAs on 37 PanNETs and matched nonneoplastic pancreata, and the miRNA levels were correlated with the clinicopathological features and patient survival data.Eight miRNAs (miRNA-27b, -122, -142–5p, -196a, -223, -590–5p, -630, and -944) were selected as candidate miRNAs. Only miR-196a level was significantly associated with stage, and mitotic count. When PanNETs were stratified into high (n = 10) and low (n = 27) miRNA-196a expression groups, miRNA-196a-high PanNETs were significantly associated with advanced pathologic T stage (50.0% vs 7.4%), N stage (50.0% vs 3.7%), higher mitotic counts (60.0% vs 3.7%), and higher Ki-67-labeling indices (60.0% vs 22.2%). In addition, high miRNA-196a expression was significantly associated with decreased overall survival (P = 0.046) and disease-free survival (P < 0.001) during a median follow-up of 37.9 months with the hazard ratio for recurrence of 16.267 (95% confidence interval = 1.732–153.789; P = 0.015).MiRNA-196a level may be a promising prognostic marker of recurrence in resected PanNETs, although further experimental investigation would be required.
