Background
The purpose of the study was to compare cancer detection rates between 12-core transrectal ultrasound-guided prostate biopsy (TRUS-Bx) and multiparametric magnetic resonance imaging (mpMRI)-guided target prostate biopsy (MRI-TBx) according to prostate-specific antigen (PSA) level in biopsy-naive patients.Patients and Methods
A retrospective study was conducted in 2009 biopsy-naive patients with suspected prostate cancer (PSA ≤20 ng/mL). Patients underwent TRUS-Bx (n = 1786) or MRI-guided target prostate biopsy (MRI-TBx; n = 223) from September 2013 to March 2017 and were stratified according to each of 4 PSA cutoffs. MRI-TBx was performed on lesions with Prostate Imaging Reporting and Data System (PI-RADS) scores of 3 to 5 on mpMRI. Clinically significant prostate cancer (csPCa) was defined as Gleason ≥7. Propensity score matching was performed using the prebiopsy variables, which included age, PSA, prostate volume, and PSA density.Results
Propensity score matching resulted in 222 patients in each group. There were significant differences between the TRUS-Bx and MRI-TBx groups in the overall detection rates of prostate cancer (41.4% vs. 55.4%; P = .003) and csPCa (30.1% vs. 42.8%; P = .005). However, across PSA cutoffs, MRI-TBx detected more prostate cancer than TRUS-Bx at PSA levels of 2.5 to <4 (29.5% vs. 56.6%; P < .001). The csPCa detection rates of TRUS-Bx and MRI-TBx did not differ significantly within the PSA cutoffs. There was a significantly higher detection rate of prostate cancer and csPCa in lesions with PI-RADS scores 4 and 5 than in those with a score of 3.Conclusion
Prebiopsy mpMRI and subsequent targeted biopsy had a higher detection rate than TRUS-Bx in patients with prostate cancer and csPCa. 相似文献2.

Background
There is a lack of real-world data regarding the treatment outcomes of chemohormonal therapy versus hormonal therapy alone in Chinese men with metastatic hormone-sensitive prostate cancer.Patients and Methods
We conducted a territory-wide, multicenter, age- and prostate-specific antigen (PSA)-matched cohort study comparing chemohormonal therapy and hormonal therapy alone in Chinese men with metastatic hormone-sensitive prostate cancer. Patient and disease characteristics were reviewed. The primary outcome was PSA progression-free survival. Secondary outcomes included clinical progression-free survival and castration resistance-free survival. Kaplan-Meier and multivariate Cox regression analyses were performed.Results
From January 2015 to July 2016, 32 Chinese men with metastatic hormone-sensitive prostate cancer were treated with chemohormonal therapy, and they were matched to 32 Chinese men who were treated with hormonal therapy alone. Patient and disease characteristics were similar between the 2 groups. The chemohormonal therapy group had a significantly better PSA progression-free survival (P = .001) and castration resistance-free survival (P = .002) than the hormonal therapy group. There was no significant difference in the clinical progression-free survival between the 2 groups. Upon multivariate Cox regression analyses, the use of chemohormonal therapy was significantly associated with a longer time to PSA progression (hazard ratio, 0.31; 95% confidence interval, 0.31-0.73; P = .008) and a longer time to castration resistance (hazard ratio, 0.38; 95% confidence interval, 0.17-0.83; P = .015), but was not associated with clinical progression.Conclusions
The use of chemohormonal therapy could prevent PSA progression and the development of castration resistance when compared with hormonal therapy alone in Chinese men with metastatic hormone-sensitive prostatic cancer. 相似文献3.

Background
The rate of noninterventional treatment (NIT) in prostate cancer (PCa) active surveillance (AS) candidates is on the rise. However, contemporary data are unavailable. We described community-based NIT rates within 16 Surveillance Epidemiology and End Results (SEER) registries between 2010 and 2014.Patients and Methods
We identified 23,360 PCa patients who fulfilled the University of California San Francisco AS criteria (prostate-specific antigen [PSA] < 10 ng/mL, clinical T stage ≤ T2a, Gleason score ≤ 6, and positive cores < 33%). Annual NIT rates as well as patient distribution according to PSA, age, number of positive cores, and clinical T stage were studied. Multivariable logistic regression analysis tested NIT predictors.Results
Between 2010 and 2014, the NIT rate increased from 30.2% to 57.5% (P = .004). Within 16 SEER registries, NIT rates ranged from 25.9% to 62%. NIT rate increased uniformly within all examined registries. Of patient and tumor characteristics (PSA > 4 ng/mL, cT2a and > 1 positive core) only the proportion of NIT patients aged < 65 years increased over time from 47.3% to 53.2% (P = .03). By multivariable logistic regression analysis predicting NIT rate, older age (odd ratio [OR] = 1.05), more contemporary year of diagnosis (OR = 1.41), and being unmarried (OR = 1.45) and uninsured (OR = 2.41) were independent predictors.Conclusion
The NIT rate has markedly increased across all examined SEER registries. Nonetheless, important differences distinguish those who received high-end NIT from low-end NIT. PCa characteristics of NIT patients remained unchanged over time. However, in addition to geographical differences in NIT rates, patient characteristics such as age, marital status, and insurance status represent potential NIT access barriers. 相似文献4.

Aims
To evaluate the prevalence, patterns of care and outcome of pathologically node-positive (pN+) prostate cancer (P-Ca) after radical prostatectomy from a provincial population database.Patients and methods
Patients were identified from a provincial cancer registry and a genitourinary cancer outcomes unit (2005–2014). Of a total of 4723 patients who underwent radical prostatectomy, 167 patients with pN+ P-Ca were identified (28/2181 from 2005–2007 and 139/2542 from 2010–2014). Persistently elevated postoperative prostate-specific antigen (PSA) ≥ 0.2 ng/ml was noted in 52 (31%) patients, 23 (44.2%) of whom had salvage androgen deprivation therapy plus radiotherapy (ADT + RT), 25 (48%) were managed with ADT alone and four (7.8%) had no treatment. Of 115 patients with postoperative PSA <0.2 ng/ml, 47 (41%) had ADT alone and 50 (43.5%) had ADT + RT. Survival estimation was carried out using the Kaplan–Meier method. The association of prognostic factors with survival was evaluated using univariate and multivariate analysis and was limited to the newer cohort (2010–2014).Results
The median age was 64 years; the median baseline PSA was 12.5 ng/mL (range 2.5–108.4). After a median follow-up of 48 months, overall survival at 5 and 10 years for the entire cohort were 89% and 81%, respectively, and distant metastasis-free survival (DMFS) at the same time points were 77% and 58%, respectively. For the newer cohort, 5-year overall survival and DMFS were 91.5% and 76%, respectively. On univariate analysis, persistently elevated postoperative PSA ≥0.2 ng/ml (P = 0.0003), seminal vesicle involvement (P = 0.027), ≥2 nodes (P = 0.035) and ADT alone (P = 0.054) had a poor prognostic impact on DMFS, whereas margin involvement had a marginally negative influence on overall survival (P = 0.06). On multivariate analysis, postoperative PSA ≥0.2 ng/ml (hazard ratio 4.4, 95% confidence interval 1.7–11.4; P = 0.002) continued to have a significant association with DMFS. On a sensitivity analysis, postoperative PSA ≥0.1 also had a significant association with DMFS on univariate and multivariate analysis (hazard ratio 3.69, 95% confidence interval 1.32–10.29; P = 0.01). Similarly, postoperative PSA ≥0.4 ng/ml had a significant association with DMFS (hazard ratio 3.87, 95% confidence interval 1.58–9.46, P = 0.003).Conclusion
This study showed a notable difference in the proportion of pN+ P-Ca patients between two different time cohorts. A significant association of persistently elevated postoperative PSA with DMFS was noted in our study. This must be accounted for while tailoring postoperative treatment in pN+ P-Ca. 相似文献5.

Background
177Lu–PSMA-617 (Lu-PSMA) is an emerging therapy in men with metastatic castration-resistant prostate cancer. Paired theranostic agents have the potential to visually identify phenotypes that will respond to targeted therapy. This study examined the value of 68Ga-HBEDD PSMA-11; prostate-specific membrane antigen (PSMA) positron emission tomography (PET) in predicting treatment response and disease progression in Lu-PSMA therapy within the context of a phase 2 prospective pilot trial.Patients and Methods
Men with progressive, symptomatic metastatic castration-resistant prostate cancer previously treated with antiandrogens (abiraterone and/or enzalutamide) and taxane-based chemotherapy were prospectively enrolled. Eligibility criteria included uptake on PSMA PET above or equal to liver activity, with no 18F-Fluoro–deoxyglucose (FDG) PET-discordant disease. Men received up to 4 cycles of Lu-PSMA at 6 weekly intervals. Repeat FDG/PSMA PET imaging was performed after completion of therapy or at prostate-specific antigen (PSA) progression. The study assessed treatment response to Lu-PSMA using PSA response and correlated treatment response (PSA) to molecular imaging parameters at enrollment.Results
Fourteen of 18 men screened underwent Lu-PSMA therapy. Ten (71%) of 14 had a PSA response (mean reduction, 59%). A ≥ 50% reduction in PSA occurred in 5 (36%), and ≥ 30% in 9 (64%). PSMA PET standardized uptake value (SUV) at screening was predictive of ≥ 30% PSA reduction: SUV max value 17 ± 9 versus 44 ± 15 (P < .007), and PSMA SUV mean 6 ± 4 versus 10 ± 4 (P < .04). FDG parameters alone, and volume or site of disease did not predict PSA response. No imaging parameters predicted ≥ 50% PSA reduction. Nine of 14 men were reimaged after treatment, revealing 3 distinct patterns of progression.Conclusion
PSMA PET plays an important role in predicting treatment response to Lu-PSMA and in identifying subsequent patterns of failure, which may aid in determining the next best treatment options. 相似文献6.

Purpose
To perform a retrospective analysis of the prognostic relevance of clinicopathologic parameters in a well-documented cohort of patients treated with all-trans-retinoic acid (ATRA)-based induction regimens in order to discover which indicators can predict a high risk of early death (ED) and patient survival.Patients and Methods
We analyzed data of 288 newly diagnosed adult acute promyelocytic leukemia patients in Hangzhou, China. The median follow-up time was 32 months (range, 6-78 months).Results
The 3-year disease-free and overall survival rates were 90.83% and 91.69%, respectively. In the multivariable analysis, older age (≥ 60 years) was the only independent risk factor for ED (hazard ratio [HR] = 15.057; P = .004). High white blood cell count was not a risk factor for ED (P = .055), but it was for relapse (HR = 2.7; P = .009). FLT3 mutation (HR = 3.9; 95% confidence interval, 1.4 to 10; P = .007) and older age (≥ 60 years) (HR = 5.3; 95% confidence interval, 2.4 to 11; P < .001) were prognostic factors for poorer disease-free and overall survival. Interestingly, CD15 negativity (HR = 0.23; P = .049) was a prognostic factor for relapse. The ED rate was 5.9% (17/288 patients).Conclusion
The perceived impact of the identification of these high-risk factors should be described in order to decide whether any modifications to treatment strategy should be entertained. 相似文献7.

Background
The role of histology subtype on the prognosis of T1-2 breast cancer patients receiving breast-conserving surgery (BCS) is not clear.Methods
The Surveillance, Epidemiology, and End Results (SEER) Program was used to compare overall survival, second primary cancer-free survival (CFS), and local recurrence risk (LR) for patients with invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC), both receiving BCS.Results
The study enrolled 196,688 patients with T1-2 disease receiving BCS, including 12,906 with ILC and 183,782 with IDC. Patients with IDC showed higher unadjusted annual rates of BCS than ILC. Five- and 10-year estimated survival rates were, respectively, 92.06% and 86.14% in ILC, compared to 90.50% and 85.26% in IDC (P = .12). In multivariable Cox regression, ILC patients showed advantage over IDC in overall survival (hazard ratio [HR] = 0.93, P = .001), whereas no significant differences in CFS (HR = 1.03, P = .33) and LR (HR = 1.17, P = .06) were found, which were consistent with results from matched cohort. In subgroup analyses, patients with grade III ILC had poorer CFS (HR = 1.23, P = .009) and higher LR (HR = 1.59, P = .01) than IDC.Conclusion
Histologic type is of prognostic importance in T1-2 patients receiving BCS, and surgeons should be cautious in performing BCS for individuals with grade III ILC. 相似文献8.

Background
Abiraterone (AA) and enzalutamide (ENZA) are increasingly being used in chemotherapy-naive patients with metastatic castration-resistant prostate cancer owing to efficacy and favorable toxicity. However, the order in which they should be administered has not been determined.Patients and Methods
We retrospectively reviewed the records of chemotherapy-naive patients with metastatic castration-resistant prostate cancer who had received sequential treatment with either AA followed by ENZA (AA-ENZA) or the converse (ENZA-AA). Prostate-specific antigen (PSA) response rates (defined as ≥ 50% PSA decline from baseline), first-line progression-free survival (PFS), second-line PFS, combined PFS (defined as first-line PFS plus second-line PFS), and overall survival are compared between the 2 sequence groups.Results
A total of 97 patients received sequential treatment with AA and ENZA; 50 patients were in the AA-ENZA group, and 47 patients were in the ENZA-AA group. The PSA response rate to first-line treatment was not significantly different between AA (48%) and ENZA (51%) (P = .840). However, a significant difference was observed in the PSA response rate to second-line treatment (AA, 6.4% vs. ENZA, 30%; P = .004). The median combined PFS was not significantly different between sequence groups (hazard ratio, 0.71; 95% confidence interval, 0.46-1.08; log-rank P = .105). The order of addition also had no significant effect on median overall survival (hazard ratio, 0.98; 95% confidence interval, 0.64-1.52; log-rank P = .834).Conclusion
With the exception of the second-line PSA response, there was no significant difference in clinical outcomes between the AA-ENZA and ENZA-AA groups. Our results might be useful reference in daily practice, especially for patients who do not have a suitable general condition for chemotherapy. 相似文献9.

Introduction
Despite the risk of morbidity and mortality associated with autologous hematopoietic cell transplantation (ASCT), there are no clear guidelines as to how to screen for these risks. This study sought to determine the utility of pulmonary function tests (PFTs) prior to ASCT on predicting posttransplant clinical outcomes.Patients and Methods
Patients undergoing ASCT between 2010 and 2012 at the Ottawa Hospital (n = 172) were reviewed. PFT results prior to ASCT were retrieved. The primary outcomes were incidence of intensive care unit (ICU) admission, Seattle Criteria for pulmonary toxicities, and transplant-related mortality (TRM).Results
PFTs were performed for 91 (53%) patients prior to ASCT. There were more smokers in the PFT cohort than the non-PFT cohort (41.8% vs. 19.8%, respectively; P < .0001). Pulmonary toxicity as measured by the Seattle Criteria did not correlate with PFT results (normal vs. abnormal, 8.1% and 6.1%, respectively; P = 1.00). There were no differences in incidence of ICU admission by PFT result (normal vs. abnormal, 2.7% vs. 8.2%, respectively; P = .61) and no difference in TRM by PFT result (normal vs. abnormal, 0% vs. 2.0%, respectively; P = 1.00).Conclusion
Despite testing patients deemed higher risk for pulmonary toxicity, abnormal PFTs did not predict for an increased risk of pulmonary toxicity, ICU admission, or TRM at our center. 相似文献10.

Aims
Delaying progression, ameliorating symptoms and maintaining quality of life (QoL) are primary aims of treatment for metastatic castrate-resistant prostate cancer (mCRPC). Real-world rather than clinical trial data about symptoms and side-effects are sparse. In EXTREQOL, patients' QoL, pain and information needs were recorded during treatment.Material and methods
Men with mCRPC from 20 UK cancer centres starting various systemic mCRPC treatments completed QoL, pain and information needs questionnaires at baseline, 3 and 6 months.Results
In total, 132 patients were recruited. Overall QoL declined significantly by 6 months (Functional Assessment of Cancer Therapy-Prostate [FACT-P] mean = –3.89, 95% confidence interval –6.7 to –1.05, P = 0.007; Trial Outcome Index [TOI] analysis mean = –3.10, 95% confidence interval –5.34 to –0.83, P = 0.007). Those who came off novel therapy and remained on luteinising hormone-releasing hormone agonist therapy alone had worse scores than patients receiving concomitant chemotherapy (Prostate Concerns Subscale mean difference = –4.45, 95% confidence interval –7.06 to –1.83, P = 0.001; TOI mean difference = –5.62, 95% confidence interval –10.97 to –0.26, P = 0.040). At 3 and 6 months, men who reported pain at baseline improved (43%, 40%), but for others pain levels remained the same (45%, 42%) or worsened (13%, 18%). Information regarding supportive care was lacking throughout the period of time on the study.Conclusion
Most mCRPC treated patients experience reduced QoL and inadequate pain control. More help with pain management and better information provision regarding supportive care is warranted. 相似文献11.

Background
INCB024360 is an oral inhibitor of the enzyme indoleamine 2,3-dioxygenase (IDO), which catalyzes the degradation of tryptophan to kynurenine. Preclinical data suggest that IDO1 inhibition by INCB024360 will increase T cell proliferation, and decrease T regulatory cells and myeloid derived suppressor cells suppressive activity. We conducted a phase II study to explore activity and pharmacodynamics of INCB024360 in patients with myelodysplastic syndromes.Patients and Methods
All patients were treated with INCB024360 600 mg orally twice a day for at least 16 weeks. Fifteen patients were enrolled. The median age was 72 years. The International Prognostic Scoring System risk was low in 27% (n = 4), intermediate-1 in 47% (n = 7), and intermediate-2 in 27% (n = 4). All patients had prior azacitidine.Results
The best response was stable disease in 12 (80%) patients and progressive disease in 3 (20%) patients. The treatment was relatively well-tolerated. One patient developed hypothyroidism and adrenal insufficiency (grade 2), and 1 patient had low testosterone level. The mean IDO expression was 39% at baseline and 26% after treatment (n = 9; P = .4). The mean burst forming unit-erythroid changed from 72 to 191 colonies/106 (n = 5; P = .036), and the mean colony forming unit-granulocye, monocyte from 62 to 180 colonies/106 (n = 6; P = .5). The mean myeloid derived suppressor cell % (CD33Lin-HLA cells) was 29.5% at baseline compared with 27.6% after treatment (n = 9; P = .7). The mean T-regulatory effector memory cell % changed from 9.6% at screening to 7.4% at end of treatment (n = 14; P = .8). The mean kynurenine/tryptophan ratio decreased from 45 at baseline to 26 (42% reduction) at cycle 2, day 1 (P < .005).Conclusion
Future directions may include testing INCB024360 early in the course of the disease. 相似文献12.

Introduction
Knowing the important factors influencing sexual function and body image might facilitate the recovery process of breast cancer survivors. Surgery type, relationship quality, and partner support might be modified to create a space for psychosexual intervention.Patients and Methods
This retrospective questionnaire-based study was performed on 128 women aged 18 to 65 years who were free of disease at time of study entry and who underwent surgical treatment for breast cancer. Diagnostic and Statistical Manual of Mental Disorders criteria were used to assessed female sexual dysfunction (FSD). Changes in Sexual Functioning Questionnaire (CSFQ) were used to measure sexual function, whereas the Body Image After Breast Cancer Questionnaire (BIBCQ) was used to assess body image. The support of the partner was evaluated by the Provisions of Social Relation Scale (PSRS).Results
The median age of the studied respondents was 52.5 ± 10.1 years. FSD was diagnosed in 27.3% women. Lower physical satisfaction in relationship (odds ratio [OR] = 2.3), undergoing mastectomy (OR = 4.1) higher level of anxiety (OR = 4.2), and shorter duration of relationship (OR = 1.1) as well as not receiving adjuvant chemotherapy (F = 3.54), higher level of emotional satisfaction in relationship (F = 20.32), longer time after completion of oncologic treatment (F = 8.76), undergoing breast-conserving therapy (compared to mastectomy) (F = 13.21), and lower level of anxiety (F = 31,25) were important factors for the prevalence of FSD and positive body image, respectively.Conclusion
Type of surgery, time after completion of treatment, level of anxiety, adjuvant chemotherapy, partner support, and satisfying quality of relationship are important factors for sexual function, sexual quality of life, and body image in female breast cancer survivors. 相似文献13.

Background
The safety of active surveillance (AS) for Gleason 6 favorable intermediate-risk (FIR) prostate cancer is unknown. To provide guidance, we examined the incidence and predictors of upgrading or upstaging for Gleason 6 FIR patients treated with radical prostatectomy.Patients and Methods
We identified 2807 men in the National Cancer Database diagnosed from 2010 to 2012 with Gleason 6 FIR disease (<50% positive biopsy cores [PBC] with either prostate-specific antigen [PSA] of 10-20 ng/mL or cT2b-T2c disease) treated with radical prostatectomy. Logistic regression was used to identify predictors of upgrading (Gleason 3+4 with tertiary Gleason 5 or Gleason ≥4+3) or upstaging (pT3-4/N1).Results
Fifty-seven percent of the cohort had PSA of 10 to 20 ng/mL; 25.5% patients with PSA of 10 to 20 ng/mL and 12.4% with cT2b to T2c disease were upgraded or upstaged. In multivariable analysis, predictors of upgrading or upstaging included increasing age (P = .026), PSA (P = .001), and percent PBC (P < .001), and black race versus white (P = .035) for patients with PSA of 10 to 20 ng/mL and increasing PSA (P = .001) and percent PBC (P < .001) for patients with cT2b to T2c disease. Men with PSA of 15.0 to 20.0 ng/mL or 37.5% to 49.9% PBC with PSA of 10 to 20 ng/mL had >30% risk of upgrading or upstaging, whereas cT2b to T2c patients with <12.5% PBC or PSA <5.0 ng/mL had <10% risk.Conclusion
We found that Gleason 6 FIR patients with cT2b to T2c tumors had a low risk of harboring higher grade or stage disease and would be reasonable AS candidates, whereas patients with PSA of 10 to 20 ng/mL had a high risk and might generally be poor AS candidates. 相似文献14.

Purpose
Emergent palliative radiation therapy (PRT) of symptomatic metastases can significantly increase the quality of life of patients with cancer. In some contexts, this treatment may be underused, but in others PRT may represent an excessively aggressive intervention. The characterization of the current use of emergent PRT is warranted for optimized value and patient-centered care.Methods and Materials
This study is a cross-sectional retrospective analysis of all emergent PRT courses at a single academic tertiary institution across 1 year.Results
A total of 214 patients received a total of 238 treatment courses. The most common indications were bone (39%) and brain (14%) metastases. Compared with outpatients, inpatients had lower mean survival rates (2 months vs 6 months; P < .001), higher rates of stopping treatment early (19.1% vs 9.0%; P = .034), and greater involvement of palliative care (44.8% vs 24.1%; P < .001), but the same mean planned fractions (9.10 vs 9.40 fractions; P = .669). In a multiple predictor survival analysis, palliative care involvement (P = .025), male sex (P = .001), ending treatment early (P = .011), and having 1 of 3 serious indications (airway compromise, leptomeningeal disease, and superior/inferior vena cava involvement; P = .007) were significantly associated with worse overall survival.Conclusions
Survival is particularly poor in patients who receive emergent PRT, and patient characteristics such as functional status and indication should be considered when determining fractionation schedule and dosing. A multi-institutional study of practice patterns and outcomes is warranted. 相似文献15.

Introduction
The clinicopathologic features and prognostic predictors of radiological part-solid lung adenocarcinomas were unclear.Methods
We retrospectively compared the clinicopathologic features and survival times of part-solid tumors with those of pure ground glass nodules (pGGNs) and pure solid tumors treated with surgery at Fudan University Shanghai Cancer Center and evaluated the prognostic implications of consolidation-to-tumor ratio (CTR), solid component size, and tumor size for part-solid lung adenocarcinomas.Results
A total of 911 patients and 988 pulmonary nodules (including 329 part-solid nodules [PSNs], 501 pGGNs, and 158 pure solid nodules) were analyzed. More female patients (p = 0.015) and nonsmokers (p = 0.003) were seen with PSNs than with pure solid nodules. The prevalence of lymphatic metastasis was lower in patients with PSNs than in those with pure solid tumors (2.2% versus 27% [p < 0.001]). The 5-year lung cancer–specific (LCS) recurrence-free survival and LCS overall survival of patients with PSNs were worse than those of patients with pGGNs (p < 0.001 and p = .042, respectively) but better than those of patients with pure solid tumors ([p < 0.001 and p < 0.0001, respectively]). CTR (OR = 12.90; 95% confidence interval [CI]: 1.85–90.04), solid component size (OR = 1.45; 95% CI: 1.28–1.64), and tumor size (OR = 1.23; 95% CI: 1.15–1.31) could predict pathologic invasive adenocarcinoma for patients with PSNs. None of them could predict the prognosis. Patients receiving sublobar resection had prognoses comparable to those of patients receiving lobectomy (p = .178 for 5-year LCS recurrence-free survival and p = .319 for 5-year LCS overall survival). The prognostic differences between patients with systemic lymph node dissection and those without systemic lymph node dissection were statistically insignificant.Conclusions
Part-solid lung adenocarcinoma showed clinicopathologic features different from those of pure solid tumor. CTR, solid component size, and tumor size could not predict the prognosis. Part-solid lung adenocarcinomas define one special clinical subtype. 相似文献16.

Background
Programmed death ligand-1 (PD-L1) is a potential predictive biomarker for immunotherapy in several malignancies. However, the expression level and clinical significance of PD-L1 in von Hippel–Lindau (VHL)-associated hereditary clear-cell renal cell carcinoma (ccRCC) remain unclear.Patients and Methods
Surgical specimens were recruited from 129 patients with sporadic ccRCC and 26 patients with VHL-associated hereditary ccRCC. The PD-L1 expression level was assessed using immunohistochemistry. Correlations between PD-L1 expression and clinicopathological features were analyzed.Results
In sporadic ccRCC, the positive expression rate of PD-L1 was 47.3% (61/129). Positive PD-L1 expression was correlated with advanced tumor T stage (P = .011), higher Fuhrman nuclear grade (P = .022), poor disease-free survival (P = .037), and sex (P = .025). In the VHL-associated hereditary ccRCC, positive PD-L1 expression rate was 34.6% (9/26), lower than that in sporadic ccRCC. Positive PD-L1 was correlated with higher Fuhrman nuclear grade (P = .008), but not with sex, age, tumor stage, or the onset age of VHL-associated tumors.Conclusion
Positive PD-L1 expression was correlated with the aggressive clinicopathological features in sporadic and VHL-associated hereditary ccRCC. Whether PD-L1 expression level in ccRCC is related to the effectiveness of programmed death-1/PD-L1 checkpoint inhibitor immunotherapy needs to be further investigated. 相似文献17.

Introduction
The American Joint Committee on Cancer (AJCC) tumor, node, metastasis classification system (TNM) staging manual has been updated and provides more specified stage grouping for prostate cancer (PCa). We aimed to validate the updated AJCC stage groups for PCa using a radical prostatectomy (RP) cohort.Patients and Methods
We analyzed the data of 3032 patients previously treated with RP for localized PCa. We stratified patients into stage groups according to the 8th edition of the AJCC manual and compared biochemical recurrence (BCR)-free survival using Kaplan-Meier analyses.Results
There were 217 patients in stage group I, 33 in IIA, 1101 in IIB, 535 in IIC, 129 in IIIA, 781 in IIIB, and 236 in IIIC. There were no significant differences in BCR-free survival between stage groups IIC and IIIA (P = .875). Subsequently, the low–Gleason score (GS) IIIA subgroup (GS ≤ 3 + 4, P = .025) showed superior BCR-free survival than the IIC group, and the high-GS IIIA subgroups (GS ≥ 4 + 3, P = .004) showed a poorer BCR-free survival than the IIC group. Furthermore, there were no significant differences between groups I and IIA (P = 330) and between groups IIA and IIB (P = .942). Our new staging system provided a better ability to discriminate the prognosis of each group. However, our study has several limitations, such as retrospective design, relatively short follow-up period, and need for further validation.Conclusion
The current AJCC prognostic groups show some contradictory results, particularly concerning prognosis of the IIC and IIIA groups. We suggest that GS be given more weight than serum prostate-specific antigen level in stage group stratification. 相似文献18.

Background
Radical cystectomy (RC) may occasionally be performed in individuals with metastatic urothelial carcinoma of the bladder (mUCB). However, the role of lymph node dissection (LND) for such cases is unknown. Thus, we tested the effect of RC on cancer-specific mortality (CSM) and overall mortality in mUCB patients and the effect of LND and its extent on CSM.Patients and Methods
Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2013), we identified patients with mUCB who underwent RC with or without LND or non-RC management. Kaplan-Meier analyses and multivariable Cox regression models (CRMs) were used, after propensity score matching. The number of removed nodes best predicting CSM was identified using cubic splines and then was tested in multivariable CRMs.Results
Of 2314 patients, 319 (13.8%) underwent RC. After 2:1 propensity score matching, CSM-free survival was 14 versus 8 months (P < .001), and overall mortality–free survival was 12 versus 7 months (P < .001) for, respectively, RC and non-RC patients. In multivariable CRMs, lower CSM (hazard ratio = 0.48; P < .001) and lower overall mortality (hazard ratio = 0.49; P < .001) rates were recorded in RC patients. LND status did not affect CSM-free survival (13 vs. 10 months; P = .1). Cubic splines-derived cutoff of ≥ 13 number of removed nodes showed better CSM-free survival (20 vs. 11 months; P = .02) and reduced CSM in CRMs (hazard ratio = 0.67; P = .02).Conclusion
Our study validates the survival benefit of RC in mUCB and highlights the importance of more extensive LND. These findings may corroborate the hypothesis of potential cytoreductive effect of surgery in the context of metastatic disease. 相似文献19.

Introduction
Major pathologic response after neoadjuvant chemotherapy (NAC) for NSCLC has been defined as 10% or less residual viable tumor without distinguishing between histologic types. We sought to investigate whether the optimal cutoff percentage of residual viable tumor for predicting survival differs between lung adenocarcinoma (ADC) and squamous cell carcinoma (SCC).Methods
Tumor slides from 272 patients treated with NAC and surgery for clinical stage II-III NSCLC (ADC, n = 192; SCC, n = 80) were reviewed. The optimal cutoff percentage of viable tumor for predicting lung cancer–specific cumulative incidence of death (LC-CID) was determined using maximally selected rank statistics. LC-CID was analyzed using a competing-risks approach. Overall survival was evaluated using Kaplan-Meier methods and Cox proportional hazard analysis.Results
Patients with SCC had a better response to NAC (median percentage of viable tumor: SCC versus ADC, 40% versus 60%; p = 0.027). Major pathologic response (≤10% viable tumor) was observed in 26% of SCC cases versus 12% of ADC cases (p = 0.004). The optimal cutoff percentage of viable tumor for LC-CID was 10% for SCC and 65% for ADC. On multivariable analysis, viable tumor 10% or less was an independent factor for better LC-CID (p = 0.035) in patients with SCC; in patients with ADC, viable tumor 65% or less was a factor for better LC-CID (p = 0.033) and overall survival (p = 0.050).Conclusions
In response to NAC, the optimal cutoff percentage of viable tumor for predicting survival differs between ADC and SCC. Our findings have implications for the pathologic assessment of resected specimens, especially in upcoming clinical trials design. 相似文献20.
