Introduction

Stereotactic body radiation therapy (SBRT) is commonly used to treat nonsurgical patients with early-stage NSCLC. There are no prospective data on the role of adjuvant chemotherapy in this setting.

Methods

Patients (≥18 years) diagnosed with clinical stages I-II NSCLC from 2004 to 2013 were identified using the National Cancer Database (n = 11,836). The Kaplan-Meier method was used to estimate overall survival (OS) distributions and the log-rank test was used to compare distributions by treatment strategy. Clinical stages I and II were subdivided according to the TNM staging and log-rank tests was used to compare survival distributions by treatment strategy within each subgroup.

Results

In patients with T2bN0, median OS in the SBRT alone and SBRT plus adjuvant chemotherapy groups were 16.5 months versus 24.2 months, respectively (95% confidence interval [CI]: 14.1–20.1 months and 18.8–33.3 months, respectively; p < .001); whereas for T3N0, median OS times were 13 months and 20.1 months, respectively (95% CI: 11.7–14.5 mohths and 17.7–21.9 months, respectively; p < .001). For tumors 4 cm or larger and node-negative disease, median OS was 15.9 months in the SBRT-alone group, and 19 months in the SBRT-plus-chemotherapy group (95% CI: 15.1–16.8 months and 17.9–20.8 months, respectively; p < .001). For patients with tumors less than 4 cm and node-negative disease, the median OS was 28.5 months in the SBRT-alone group and 24.3 months in the SBRT-plus-chemotherapy group (95% CI: 27.4–29.4 months and 22.8–26.1 months, respectively; p < .001).

Conclusions

SBRT followed by adjuvant chemotherapy was associated with improved OS in comparison with SBRT alone in patients with T greater than or equal to 4 cm, similar to that seen after surgery.  相似文献

Introduction

Clinical variables describing the natural history and longitudinal therapy outcomes of stage IV anaplastic lymphoma kinase gene rearrangement positive (ALK-positive) NSCLC and their relationship with long-term overall survival (OS) have not previously been described in detail.

Methods

Patients with stage IV NSCLC treated with an ALK inhibitor at the University of Colorado Cancer Center from 2009 through November 2017 were identified retrospectively. OS curves were constructed by using Kaplan-Meier methods. Multivariate Cox proportional hazard analysis was used to determine the relationship of variables with OS.

Results

Of the 110 patients with ALK-positive NSCLC who were identified, 105 received crizotinib as their initial ALK inhibitor. With a median follow-up time of 47 months, the median OS time from diagnosis of stage IV disease was 81 months (6.8 years). Brain metastases at diagnosis of stage IV disease (hazard ratio = 1.01, p = 0.971) and year of stage IV presentation (p = 0.887) did not influence OS. More organs with tumor at diagnosis of stage IV disease was associated with worse OS (HR = 1.49 for each additional organ with disease, including the CNS [p = 0.002]). Each additional month of pemetrexed-based therapy was associated with a 7% relative decrease in risk of death.

Conclusion

Patients with stage IV ALK-positive NSCLC can have prolonged OS. Brain metastases at diagnosis of stage IV disease does not influence OS. Having more organs involved with tumor at stage IV presentation is associated with worse outcomes. Prolonged benefit from pemetrexed is associated with better outcomes.  相似文献

Background

Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.

Patients and Methods

We retrospectively evaluated the incidence of CVEs on 233 consecutive patients with chronic myeloid leukemia, of which 116 were treated with imatinib, 75 with dasatinib, and 42 with nilotinib. The median follow-up was 2047, 1712, and 1773 days, respectively.

Results

The cumulative incidence of CVEs was 4.29%. Three events occurred during dasatinib treatment, 6 during nilotinib treatment, and none during imatinib treatment (P ≤ .001). Arterial occlusive events occurred in 2 (2.6%) of 75 patients treated with dasatinib and in 6 (14.2%) of 42 patients treated with nilotinib (P ≤ .001). Furthermore, all of them occurred in patients with high-risk (n = 2) and very high-risk (n = 6) cardiovascular risk, contributing to 4.3% of mortality.

Conclusion

CVEs were more frequent in patients treated with second-generation tyrosine kinase inhibitors. Arterial occlusive events were more frequent in patients treated with nilotinib, with high and very high cardiovascular risk.  相似文献

Background

Colon cancer is the third most frequent cancer diagnosis, and primary payer status has been shown to be associated with treatment modalities and survival in cancer patients. The goal of our study was to determine the between-insurance differences in survival in patients with clinical stage III colon cancer using data from the National Cancer Database (NCDB).

Materials and Methods

We identified 130,998 patients with clinical stage III colon cancer in the NCDB diagnosed from 2004 to 2012. Kaplan-Meier curves and multivariable Cox regression models were used to determine the association between insurance status and survival.

Results

Patients with private insurance plans were 28%, 30%, and 16% less likely to die than were uninsured patients, Medicaid recipients, and Medicare beneficiaries, respectively. Medicare patients were 14% were less likely to die compared with uninsured patients. Patients receiving chemotherapy were, on average, 65% less likely to die compared with the patients not receiving chemotherapy.

Conclusion

Private insurance and a greater socioeconomic status were associated with increased patient survival compared with other insurance plans or the lack of insurance. Future research should continue to unravel how socioeconomic status and insurance status contribute to the quality of care and survival of oncologic patients.  相似文献

Introduction

The purpose of this study was to identify predictors of overall (OS) and liver progression-free survival (LPFS) following Yttrium-90 radioembolization (RAE) of heavily pretreated patients with colorectal cancer liver metastases (CLM), as well as to create and validate a predictive nomogram for OS.

Materials and Methods

Metabolic, anatomic, laboratory, pathologic, genetic, primary disease, and procedure-related factors, as well as pre- and post-RAE therapies in 103 patients with CLM treated with RAE from September 15, 2009 to March 21, 2017 were analyzed. LPFS was defined by Response Evaluation Criteria In Solid Tumors 1.1 and European Organization for Research and Treatment of Cancer criteria. Prognosticators of OS and LPFS were selected using univariate Cox regression, adjusted for clustering and competing risk analysis (for LPFS), and subsequently tested in multivariate analysis (MVA). The nomogram was built using R statistical software and internally validated using bootstrap resampling.

Results

Patients received RAE at a median of 30.9 months (range, 3.4-161.7 months) after detection of CLM. The median OS and LPFS were 11.3 months (95% confidence interval, 7.9-15.1 months) and 4 months (95% confidence interval, 3.3-4.8 months), respectively. Of the 40 parameters tested, 6 were independently associated with OS in MVA. These baseline parameters included number of extrahepatic disease sites (P < .001), carcinoembryonic antigen (P < .001), albumin (P = .005), alanine aminotransferase level (P < .001), tumor differentiation level (P < .001), and the sum of the 2 largest tumor diameters (P < .001). The 1-year OS of patients with total points of < 25 versus > 80 was 90% and 10%, respectively. Bootstrap resampling showed good discrimination (optimism corrected c-index = 0.745) and calibration (mean absolute prediction error = 0.299) of the nomogram. Only baseline maximum standardized uptake value was significant in MVA for LPFS prediction (P < .001; SHR = 1.06).

Conclusion

The developed nomogram included 6 pre-RAE parameters and provided good prediction of survival post-RAE in heavily pretreated patients. Baseline maximum standardized uptake value was the single significant predictor of LPFS.  相似文献

Background

There are no validated markers that predict response or resistance in patients with metastatic clear-cell renal cell carcinoma (mccRCC) treated with vascular endothelial growth factor receptor tyrosine kinase inhibitors such as sunitinib and pazopanib. Recently, single nucleotide polymorphism (SNP) rs2981582 in Fibroblast Growth Factor Receptor 2 (FGFR2) was found to be associated with clinical outcome in patients with mccRCC treated with pazopanib and sunitinib. We aimed to validate these findings in patients treated with sunitinib.

Materials and Methods

Germline DNA was collected in patients with mccRCC starting first-line systemic therapy with sunitinib. SNP rs2981582 in FGFR2 C>T was genotyped. Association of the genotype with response rate, tumor shrinkage, median progression-free survival (mPFS), and median overall survival (mOS) was studied.

Results

We collected clinical data from 154 patients with available germline DNA. Baseline prognostic markers were well-balanced between both subgroups. Patients with the TT genotype had a poorer outcome compared with patients with the CT/CC genotype. The median shrinkage of selected tumor target lesions during treatment with sunitinib was ?16% versus ?31% (P = .002), mPFS was 8 versus 15 months (P = .0007), and mOS was 22 versus 33 months (P = .04), respectively. On multivariate analysis, rs2981582 remained an independent predictor of PFS (hazard ratio, 2.858; 95% confidence interval, 1.659-4.923; P < .0001) and OS (hazard ratio, 1.795; 95% confidence interval, 1.003-3.212; P = .049).

Conclusion

Polymorphism rs2981582 in FGFR2 is correlated to PFS and OS in patients with mccRCC treated with sunitinib. Prospective validation of the impact of this SNP is warranted.  相似文献

Background

The safety and efficacy of targeted therapy in older patients (≥ 70 years) with metastatic colorectal cancer is not well evaluated.

Patients and Methods

Outcomes of older patients (including overall survival [OS], progression-free survival [PFS], toxicity, and quality of life [QoL]) were compared to young patients using data from 2 large previously reported clinical trials, CO.17 (cetuximab vs. best supportive care) and CO.20 (cetuximab plus placebo vs. cetuximab plus brivanib). Only patients with wild-type KRAS tumors were included.

Results

A total of 251 (26.3%) of 955 patients were ≥ 70 years old. No significant differences in OS, PFS, or grade 3/4 adverse events were observed between older and younger patients treated with cetuximab (or cetuximab with placebo) in either trial. Younger patients trended toward superior OS in both CO.17 (hazard ratio = 1.80; P = .16) and CO.20 (hazard ratio = 1.34; P = .07). QoL maintenance favored younger patients in CO.17 (3.6 vs. 5.7 months; P = .046) but no difference of QoL maintenance was observed in the larger CO.20 trial (1.7 vs. 1.8 months; P = .64). Combination therapy of cetuximab and brivanib was significantly more toxic in older adults (87% vs. 77%; P = .03).

Conclusion

OS, PFS, and toxicities were similar between older and younger patients with wild-type KRAS metastatic colorectal cancer when treated with cetuximab. Both age groups likely experience similar QoL maintenance with cetuximab. Dual targeted therapy was significantly more toxic in older patients.  相似文献

Introduction

Data on immuno-oncology agents in Chinese patients are limited despite a need for new therapies. We evaluated the efficacy and safety of nivolumab in a predominantly Chinese patient population with previously treated NSCLC.

Methods

CheckMate 078 was a randomized, open-label, phase III clinical trial in patients from China, Russia, and Singapore with squamous or nonsquamous NSCLC that had progressed during/after platinum-based doublet chemotherapy (ClinicalTrials.gov: NCT02613507). Patients with EGFR/ALK alterations were excluded. Patients (N = 504) were randomized 2:1 to nivolumab (3 mg/kg every 2 weeks) or docetaxel (75 mg/m2 every 3 weeks), stratified by performance status, tumor histology, and tumor programmed death ligand 1 expression. The primary endpoint was overall survival (OS); secondary endpoints included objective response rate, progression-free survival, and safety.

Results

OS was significantly improved with nivolumab (n = 338) versus docetaxel (n = 166); median OS (95% confidence interval): 12.0 (10.4–14.0) versus 9.6 (7.6–11.2) months, respectively; hazard ratio (97.7% confidence interval): 0.68 (0.52–0.90); p = 0.0006. Objective response rate was 17% with nivolumab versus 4% with docetaxel; median duration of response was not reached versus 5.3 months. Minimum follow-up was 8.8 months. The frequency of grade 3 or greater treatment-related adverse events was 10% with nivolumab and 48% with docetaxel.

Conclusions

This is the first phase III study in a predominantly Chinese population reporting results with a programmed death 1 inhibitor. In this population with previously treated advanced NSCLC, nivolumab improved OS versus docetaxel. Results were consistent with global CheckMate 017 and 057 studies.  相似文献

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

Background

Although most cases of herpes zoster (HZ) are self-limited, lymphoma patients are at greater risk for recurrences and more serious and atypical complications that can delay scheduled anti-lymphoma treatment or prevent its continuation.

Patients and Methods

This is a cohort study with a retrospective chart review of 415 patients diagnosed with lymphoma to determine the incidence and risk factors for developing HZ among this population. Data collected included date of diagnosis, patient’s age, last follow-up or death, stage and presentation of lymphoma, treatment type, baseline laboratory tests, and comorbidities. Patients with a diagnosis of HZ at any time during their course of illness were identified. Patients were divided into various subgroups to analyze their risk of developing HZ individually. The frequencies of each categorical variable were compared with χ2 tests. Relative risks were calculated using 95% confidence intervals (CIs).

Results

During a median follow-up of 8.9 years, 46 cases of HZ were identified, with an overall incidence density of 11.1%. Higher rates of HZ were associated with lymphocytopenia (P = .038), presentation (P = .030), stage (P = .034), autologous stem cell transplant (P = .019), multiple courses of chemotherapy (P = .035), and fludarabine therapy (P = .002). Those who received what we labeled as ‘highly immunosuppressive chemotherapy’ had 2.9 times the risk to develop HZ than those who did not receive this therapy (95% CI, 1.47-5.623; P < .001).

Conclusions

Receiving highly immunosuppressive chemotherapy is an independent risk factor for developing HZ. Patients with the risk factors described here might benefit from antiviral prophylaxis against HZ.  相似文献

Background

Gastrointestinal (GI) cancer patients may not be considered for therapy with fluoropyrimidines (FPs) because of previous cardiovascular (CV) toxicity or preexisting risk factors; such patients may benefit from raltitrexed-based therapy.

Patients and Methods

Patient, tumor, and treatment characteristics, as well as clinical outcomes of all consecutively treated patients with raltitrexed at the Royal Marsden Hospital between October 1998 and July 2011 were examined. GI cancer patients who developed CV toxicity as a result of FPs and those with significant CV risk factors receiving raltitrexed were included in this analysis.

Results

A total of 247 patients (155 and 92 with CV FP-related CV toxicities and significant CV risk factors, respectively) treated with raltitrexed alone or in combination were examined after a median follow-up of 47.1 months. CV toxicity profiles of patients receiving capecitabine (n = 110) and 5-fluorouracil (n = 45) were largely similar. Of raltitrexed-treated patients, 13 (5%) experienced CV toxicities and 1 (< 0.1%) died as a result of myocardial infarction. The median progression-free survival (PFS) and overall survival (OS) were 36.0 months (95% confidence interval [CI], 26.5-48.6) and 44.3 months (95% CI, 33.1-56.8), respectively. The 5-year survival for early stage GI malignancies (n = 140) was 62.0% (95% CI, 50.1-71.9). Median PFS and OS were not reached in this group (interquartile range = 38.4 months to NR); median PFS and OS for advanced GI malignancies (n = 107) were 18.8 (95% CI, 11.9-25.7) and 23.7 months (95% CI, 17.0-26.9), respectively.

Conclusion

A raltitrexed-based regimen is well-tolerated therapy with comparable efficacy to FPs in patients with GI malignancies with significant CV toxicities or risk factors.  相似文献

Background

Brain metastases (BM) occur frequently in patients with metastatic kidney cancer and are a significant source of morbidity and mortality. Although historically associated with a poor prognosis, survival outcomes for patients in the modern era are incompletely characterized. In particular, outcomes after adjusting for systemic therapy administration and International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk factors are not well-known.

Patients and Methods

A retrospective database of patients with metastatic renal cell carcinoma (RCC) treated at University of Texas Southwestern Medical Center between 2006 and 2015 was created. Data relevant to their diagnosis, treatment course, and outcomes were systematically collected. Survival was analyzed by the Kaplan-Meier method. Patients with BM were compared with patients without BM after adjusting for the timing of BM diagnosis, either prior to or during first-line systemic therapy. The impact of stratification according to IMDC risk group was assessed.

Results

A total of 56 (28.4%) of 268 patients with metastatic RCC were diagnosed with BM prior to or during first-line systemic therapy. Median overall survival (OS) for systemic therapy-naive patients with BM compared with matched patients without BM was 19.5 versus 28.7 months (P = .0117). When analyzed according to IMDC risk group, the median OS for patients with BM was similar for favorable- and intermediate-risk patients (not reached vs. not reached; and 29.0 vs. 36.7 months; P = .5254), and inferior for poor-risk patients (3.5 vs. 9.4 months; P = .0462). For patients developing BM while on first-line systemic therapy, survival from the time of progression did not significantly differ by presence or absence of BM (11.8 vs. 17.8 months; P = .6658).

Conclusions

Survival rates for patients with BM are significantly better than historical reports. After adjusting for systemic therapy, the survival rates of patients with BM in favorable- and intermediate-risk groups were remarkably better than expected and not statistically different from patients without BM, though this represents a single institution experience, and numbers are modest.  相似文献

Introduction

Approximately 50% of locally advanced or metastatic breast cancer (MBC) patients treated with first-line exemestane do not show objective response and currently there are no reliable biomarkers to predict the outcome of patients using this therapy. The constitutive genetic background might be responsible for differences in the outcome of exemestane-treated patients. We designed a prospective study to investigate the role of germ line polymorphisms as biomarkers of survival.

Patients and Methods

Three hundred two locally advanced or MBC patients treated with first-line exemestane were genotyped for 74 germ line polymorphisms in 39 candidate genes involved in drug activity, hormone balance, DNA replication and repair, and cell signaling pathways. Associations with progression-free survival (PFS) and overall survival (OS) were tested with multivariate Cox regression. Bootstrap resampling was used as an internal assessment of results reproducibility.

Results

Cytochrome P450 19A1-rs10046TC/CC, solute carrier organic anion transporter 1B1-rs4149056TT, adenosine triphosphate binding cassette subfamily G member 2-rs2046134GG, fibroblast growth factor receptor–4-rs351855TT, and X-ray repair cross complementing 3-rs861539TT were significantly associated with PFS and then combined into a risk score (0-1, 2, 3, or 4-6 risk points). Patients with the highest risk score (4-6 risk points) compared with ones with the lowest score (0-1 risk points) had a median PFS of 10 months versus 26.3 months (adjusted hazard ratio [AdjHR], 3.12 [95% confidence interval (CI), 2.18-4.48]; P < .001) and a median OS of 38.9 months versus 63.0 months (AdjHR, 2.41 [95% CI, 1.22-4.79], P = .012), respectively.

Conclusion

In this study we defined a score including 5 polymorphisms to stratify patients for PFS and OS. This score, if validated, might be translated to personalize locally advanced or MBC patient treatment and management.  相似文献

Introduction

Immunotherapy has revolutionized the treatment of NSCLC, but little is known about the activity of programmed cell death 1 and programmed death ligand 1 blockade across age groups.

Methods

We retrospectively evaluated patients with NSCLC who initiated programmed cell death 1 and programmed death ligand 1 inhibitors from January 2013 through July 2017. Medical records and radiographic imaging were reviewed to determine progression-free survival (PFS) and overall survival (OS). We also compared immunotherapy-related toxicities, steroid use, and hospitalizations by age.

Results

Of the 245 patients, 26.1% were younger than 60 years, 31.4% were age 60 to 69 years, 31.0% were age 70 to 79 years, and 11.4% were age 80 years or older. The median PFS times by age group were as follows: younger than 60 years, 1.81 months; age 60 to 69 years, 2.53 months; age 70 to 79 years, 3.75 months; and age 80 years or older, 1.64 months (log-rank p value = 0.055). The median OS times by age group were as follows: younger than 60 years, 13.01 months; age 60 to 69 years, 14.56 months; age 70 to 79 years, 12.92 months; and age 80 years or older, 3.62 months (log-rank p value = 0.011). Rates of immunotherapy-related toxicities, steroid use, and hospitalizations did not differ by age.

Conclusions

Although the OS and PFS benefits of immunotherapy differ by age, the rates of toxicity are similar regardless of age.  相似文献

Background

Recent trends have identified increasing number of young individuals with rectal and colon cancers. These individuals, who are younger than 50 years old, in most instances would not meet screening guidelines. We aimed to report the characteristics and trend of the rising proportion of young individuals being diagnosed with rectal and colon cancers at our institutions.

Patients and Methods

This study included 3381 rectal and colon cancer patients from the Mayo Clinic cancer registry from 1972 to 2017 who were diagnosed with rectal or colon cancer and who were < 50 years old. Patient and cancer characteristics are described. The Cochran-Armitage trend test was used to see if the change in percentage diagnosed at age < 50 years had a significant trend over the years. A linear regression model was fit to estimate the percentage change per year when the trend was approximately linear.

Results

The percentage of patients diagnosed with rectal or colon cancer in different age categories over the years showed a rising trend for individuals aged < 50. Most of these tumors were distal (rectum, left-sided colon, and right-sided colon were 49.8%, 28.8%, and 21.4%, respectively). This was more so for patients < 50 diagnosed with rectal cancer, which showed a linear increase at a rate of 0.26% per year (P < .001).

Conclusion

Our study affirms the rising proportion of colorectal cancers found in young individuals, with a linear ongoing rise of rectal cancers in particular. This may have implications for the current screening recommendations for colorectal cancers, which are already being revised.  相似文献

Background

In the Surveillance, Epidemiology, and End Results population-based data, the survival curves reversed between T4N0 (stages IIB or IIC) and T1-2N1 (stage IIIA) in rectal cancer. However, T4N0 had a higher stage than T1-2N1 in the current colorectal staging system.

Patients and Methods

We analyzed 1804 patients with rectal cancer who were treated with preoperative chemoradiotherapy and curative surgery. We grouped patients by pathologic stage, and recurrence-free survival (RFS) and overall survival rates were calculated and compared for each stage. We evaluated prognostic factors that influenced recurrence and survival.

Results

In the recurrence and survival analysis, 3-year RFS rates were 95.9% for ypStage 0, 94.0% for ypStage I, 78.9% for ypStage IIA, 55.8% for ypStage IIB/C, 80.2% for ypStage IIIA, 64.6% for ypStage IIIB, and 44.9% for ypStage IIIC. Patients with ypStage IIB/C showed significantly worse RFS (P = .004) than did those with ypStage IIIA. The ypStage IIB/C group showed significantly higher rates of both locoregional recurrence (24.3% vs. 5.5%; P = .02) and distant metastasis (31.6% vs. 17.1%; P = .048) than did the ypStage IIIA group. Compared with ypStage IIIA, ypStage IIB/C showed significantly higher pre-chemoradiotherapy carcinoembryonic antigen (P = .004), circumferential radial margin involvement (P = .001), and positive perineural invasion (P = .014).

Conclusion

Patients with rectal cancer staged ypT4N0 were associated with higher locoregional recurrence and distant metastasis rates than those staged ypT1-2N1 in the current staging system.  相似文献

Background

The aim of this study was to determine if, in inflammatory breast cancer (IBC), baseline metabolic activity (maximum standardized uptake value [SUVmax]) of primary tumor and involved regional lymph nodes (IRLN) are prognostic markers of response after neoadjuvant systemic therapy (NAS).

Patients and Methods

Baseline 2-deoxy-2-[18F]fluoro-D-glucose (FDG) positron emission tomography/computed tomography scans were retrospectively reviewed among 61 women with IBC who received NAS, had mastectomy, and had available pathology reports. Primary tumor and IRLN SUVmax were compared between patients with a pathologic complete response (pCR) versus those with residual disease after NAS. A multivariate Cox model was fit to evaluate the effects of SUVmax on overall survival, adjusting for pCR and stratified by receptor status and disease stage.

Results

SUVmax in primary IBC tumors tended to increase with tumor grade (trend test P = .06) and was lower for stage III, non–triple-negative (TN) versus stage III, TN and stage IV, non-TN disease (P = .04). Neither primary tumor nor IRLN SUVmax was significantly different comparing pCR versus residual disease after NAS. Adjusting for pathology response in the overall survival model stratified by stage and receptor status, baseline SUVmax in primary IBC tumor was associated with an estimated hazard ratio of 1.10 (95% confidence interval, 0.97-1.25; P = .15) for patients with stage III, TN and stage IV, non-TN disease. This hazard ratio corresponded to a 1.74-fold risk of death with 1 standard deviation (SD = 5.9) increase in baseline SUVmax in primary IBC tumor.

Conclusion

2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography provides prognostic information for newly diagnosed IBC. Larger studies are needed to confirm these findings and assess how such early information could affect treatment choices for IBC in the neoadjuvant setting.  相似文献

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

Background

The prognostic value of tumor sidedness in metastatic colorectal cancer (CRC) has been established, but its impact on nonmetastatic disease remains unclear. Our study aimed to explore the prognostic effect of tumor sidedness by subgroup survival analyses, according to histology and tumor grade in stage I-IV CRCs.

Methods

A retrospective population-based study was conducted based on Surveillance, Epidemiology and End Results (SEER) data. Population data in the SEER 9 registry (1975-2014) were used to determine survival trends of CRCs, and associated population data in the SEER 18 registry (2000 to 2014) were used to assess the prognostic impact of tumor sidedness on CRCs.

Results

The 5-year cause-specific survival for all subgroups of CRCs improved from 1975 to 2014. Of 238,826 patients, 44.2% had right-sided cancer. Patients with right-sided cancer were more likely to be older, to be women, to have disease of mucinous or signet-ring cell histology, to have more poorly differentiated tumors, and to be diagnosed with a more advanced disease stage. Multivariate Cox regression showed stage I-II right-sided cancers had better cause-specific survival than the left-sided cancers (left colon: hazard ratio [HR] = 1.091, 95% confidence interval [CI], 1.052-1.132; rectum: HR = 1.363; 95% CI, 1.304-1.425; P < .001), while stage III and IV right-sided cancers had worse cause-specific survival. In subgroup analyses by histology and tumor grade within stage III CRCs, right-sided poorly differentiated mucinous adenocarcinoma showed significantly better survival (left colon: HR = 1.352; 95% CI, 1.145-1.596; rectum: HR = 1.125; 95% CI, 0.916-1.381; P = .002).

Conclusion

The relationship between sidedness and prognosis in CRCs depends on stage and histopathologic characteristics, especially for stage III disease.  相似文献
