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2.

Aims
To assess the impact of weekly scheduled peer review of head and neck contours for definitive and adjuvant radiotherapy cases based on rates of recommended changes.Materials and methods
Retrospective analysis of a prospective database. Recommended changes were prospectively classified as ‘major’ (change in gross tumour volume and/or high-dose clinical target volume, dose/fractionation) or ‘minor’ (change in intermediate or elective dose clinical target volumes or organs at risk). Univariate analysis to explore associations between recommended changes and tumour site/stage and radical/adjuvant indication.Results
In total, 307/375 (82%) head and neck cases treated with volumetric-modulated arc therapy were prospectively peer reviewed over a 12-month period; 195 (64%) cases received definitive and 112 (36%) received adjuvant radiotherapy. Overall, 43/307 (14.0%) changes were recommended within the peer review meetings. This comprised 27/307 (8.8%) major changes and 16/307 (5.2%) minor changes; 33/43 (77%) changes were in the clinical target volume. Rates of recommended changes were significantly higher for adjuvant versus definitive radiotherapy (odds ratio 2.26, P = 0.014) and for larynx compared with oropharynx (odds ratio 3.02, P = 0.02). There was no overall correlation between clinician experience and rates of change (P = 0.62).Conclusion
Routine weekly meeting contour-based peer review resulted in a number of major and minor changes to treatment. Compliance was high. Peer review was potentially beneficial for all tumour sites/stages/indications and any degree of clinician experience. 相似文献3.

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4.

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5.

Background
Given the lack of established indications for elective nodal irradiation (ENI) in ypN0 patients after neoadjuvant chemotherapy (NAC) and breast-conserving surgery (BCS), we set out to investigate the role of ENI in ypN0 patients according to subtype and pathologic complete remission (pCR) status.Patients and Methods
We analyzed 261 patients who received NAC followed by BCS and adjuvant radiotherapy in 13 institutions of the Korean Radiation Oncology Group from 2005 to 2011. The tumors were classified into one of 3 subtypes: luminal (estrogen receptor positive or progesterone receptor positive and HER2 negative), HER2 (HER2 positive), or triple negative (estrogen receptor, progesterone receptor, and HER2 negative). We compared locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) according to ENI in different subgroups generated by the subtype and pCR statuses.Results
In all patients, the 5-year LRC, DFS, and OS rates were 96.0%, 91.0%, and 96.8%, respectively. In all patients, axillary lymph node dissection was found to be the only favorable factor for LRC (P = .023) and DFS (P = .001). Age ≥ 50 years (P = .027), negative resection margin (P = .002), and axillary lymph node dissection (P = .002) were all favorable factors for OS. ENI did not affect LRC, DFS, or OS. Subgroup analysis by tumor subtype and pCR showed that ENI was not associated with greater LRC or DFS in any subgroups.Conclusion
In ypN0 patients after NAC and BCS, ENI did not improve LRC or survival, regardless of subtype or primary tumor response. This result should be verified through larger prospective trials. 相似文献6.

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7.

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8.

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9.

Background
Radium 223 was introduced for metastatic castration-resistant prostate cancer based on the results of a randomized controlled trial showing risk reduction for death and skeletal events. Our aim was to evaluate the outcome of patients receiving radium 223 in a real-world setting.Patients and Methods
We conducted a multicenter retrospective analysis in the Triveneto region of Italy.Results
One hundred fifty-eight patients received radium 223 in our region. After a median follow-up of 9.5 months, 75 patients died. The median overall survival (OS) was 14.2 months, and the median progression-free survival (PFS) was 6.2 months. Seventy-one (45%) patients achieved progression as best response. Thirty-seven (23%) patients stopped the treatment early because of progression. Eastern Cooperative Oncology Group performance status was prognostic for OS (18.4 vs. 12.3 vs. 7.5 months; 0 vs. 1, P = .0062; 0 vs. 2, P = .0002), whereas previous prostatectomy or docetaxel exposure were not. A neutrophil to lymphocytes ratio ≥ 3 significantly impacted OS (18.1 vs. 9.7 months; P < .001) and slightly impacted PFS (6.6 vs. 5.6 months; P = .05). Patients with a baseline alkaline phosphatase (ALP) value ≥ 220 U/L had worse OS and PFS (24.1 vs. 10.5 months; 7.2 vs. 5.5 months; P < .001). Patients with changes in ALP value achieved better OS (P = .029) and PFS (P = .002). There was no difference according to the line of therapy (0 vs. ≥ 1; P = .490). The main grade 3/4 toxicities were anemia, asthenia, and thrombocytopenia.Conclusion
This large real-world report confirms comparable OS and PFS data when compared with the pivotal study, as well as the predictive role of ALP and neutrophil to lymphocytes ratio. The definition of the optimal position of radium 223 in the treatment of metastatic castration-resistant prostate cancer has still to be defined. 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
Smoking increases the risk of developing renal cell carcinoma (RCC) but the effect of tobacco consumption on survival outcome of patients with metastatic RCC (mRCC) treated with targeted therapies has not been well characterized.Patients and Methods
The primary outcome was overall survival (OS) and secondary outcome was progression-free survival (PFS). Patients with mRCC were categorized as current, former, and nonsmokers at the time of starting targeted therapy. Smoking data from 1980 patients with mRCC treated with targeted therapy were collected through the International mRCC Database Consortium (IMDC) from 12 international cancer centers.Results
Although former and nonsmokers had comparable OS times (23.8 vs. 23.4 months; P = .898), current smokers had significantly shorter OS (16.1 months; P < .001) than nonsmokers. Current but not former smoking status was an independent poor prognosis factor (hazard ratio [HR], 1.3; P = .002) when adjusted for the IMDC risk criteria. Each pack-year increased the risk of death by 1% (HR, 1.01; P = .036). The duration of first-line therapy response was not different and was 7.7 months versus 7.5 months versus 6.4 months in never, former (P = .609), and current smokers (P = .839), respectively.Conclusion
Active smoking is associated with diminished OS in mRCC patients treated with targeted therapy agents. However, patients who quit smoking returned to a similar risk of death from RCC compared with patients who never smoked. Smoking cessation should be a counseling priority among mRCC patients receiving targeted agents and smoking should be considered as a confounding factor in major clinical trials. 相似文献12.

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13.

Aims
Select patients with brain metastases receive stereotactic radiosurgery (SRS) with the objective of improving survival and intracranial disease control. Brain metastases number and volume are prognostic factors used to inform patient selection. The aim of this study was to assess the rate of change of brain metastases size and number (growth kinetics) between the diagnostic and day of SRS magnetic resonance imaging (MRI) scans.Materials and Methods
All patients treated with Gamma Knife SRS between October 2015 and April 2017 were included in this single-centre retrospective analysis. Brain metastases number and diameter were recorded at diagnosis and treatment. For patients with multiple brain metastases, the largest lesion was the index lesion. Distant intracranial control and overall survival were reported from the date of SRS.Results
In total, 146 patients received 156 episodes of SRS. The median interval between diagnostic and SRS MRI was 20 days (range 1–68). Interval growth in the index lesion of at least 3 mm or the development of a new brain metastasis was noted in 60.2% of patients. This was associated with age less than 60 years (P = 0.001), Eastern Cooperative Oncology Group (ECOG) performance status 2 or above (P = 0.04), non-small cell lung carcinoma (NSCLC) (P = 0.03) or melanoma histologies (P = 0.05) and uncontrolled extracranial disease (P = 0.05). These patients were also more likely to develop distant intracranial recurrence (P = 0.046). Clinically significant growth was not associated with scan interval or differences in overall survival. The Kaplan–Meier estimate of probability of survival at 12 months was 59.3% (95% confidence interval 46.7–75.2%) for all patients.Conclusion
Intracranial progression between diagnosis and day of SRS is common. Risk factors are uncontrolled extracranial disease, poorer performance status, NSCLC or melanoma histologies and age less than 60 years. These patients would benefit from an MRI closer to treatment to inform patient selection and target delineation for SRS planning. 相似文献14.

Purpose
To determine a subset of women who could undergo ovary-sparing radical cystectomy (OSRC) for bladder cancer without compromising oncologic safety.Patients and Methods
A retrospective review was performed of 164 consecutive women who underwent cystectomy at a single tertiary-care center from 1997 to 2018. Clinicopathologic and preoperative radiographic data were reviewed. Univariable and multivariable logistic regression models adjusting for pathologic stage, lymphovascular invasion (LVI), and carcinomain-situ were performed to evaluate the risk of ovarian and reproductive organ (RO) involvement.Results
A total of 123 women with a median age of 71 years underwent radical cystectomy (RC) with removal of ROs for primary bladder cancer. Nineteen women (15%) had RO involvement by bladder cancer, and 5 of them (4%) were specifically found to have ovarian involvement. Patients with ovarian involvement of bladder cancer had more locally advanced disease (P = .01), LVI (P = .003) and positive margins (P = .003). On multivariable logistic regression, ≥ pT3 (odds ratio = 10.2; 95% confidence interval, 2.0-51.6; P = .005) and LVI (odds ratio = 3.9; 95% confidence interval, 1.1-14.2; P = .037) were associated with increased risk of RO involvement. Among 15 patients excluded for having a nonbladder primary malignancy, a third had RO involvement, and 2 (13%) had ovarian metastases. No women in our cohort had a primary ovarian malignancy detected at the time of RC.Conclusion
Women with ovarian involvement by malignancy at the time of RC either had locally advanced disease with LVI or a non-bladder primary malignancy. The risk of incompletely resecting the primary malignancy would be rare if OSRC was performed on women with organ-confined (≤T2) urothelial carcinoma. 相似文献15.

Introduction
The aim of this study was to characterize treatment trends and outcomes of women who have preexisting cardiovascular disease (CVD) prior to the diagnosis of breast cancer.Patients and Methods
This represented a retrospective, population-based cohort study that analyzed pooled data from the provincial cancer registry, physician billing claims, hospital discharge abstracts, ambulatory care, and the 2011 census in a large Canadian province. Multivariable logistic regression was performed to identify the associations of CVD with breast cancer treatment and outcomes. Kaplan-Meier analyses were conducted and survival was compared between CVD and non-CVD groups. Cox regression models were constructed to determine the effect of CVD on overall and cancer-specific survival.Results
A total of 25,594 women with breast cancer were eligible and included in the current analysis. Preexisting CVD was associated with a lower likelihood of receiving chemotherapy (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.48-0.66; P < .0001) and radiotherapy (OR, 0.75; 95% CI, 0.67-0.83; P < .0001), but a higher probability of undergoing mastectomy (OR, 1.13; 95% CI, 1.03-1.25; P = .011). Unadjusted Kaplan-Meier analyses showed that individuals with preexisting CVD experienced worse median overall and cancer-specific survival when compared with those without CVD (87 vs. 150 months and 106 vs. 131 months, respectively; both P < .0001). Adjusting for measured confounders, the presence of preexisting CVD continued to predict for worse overall survival (hazard ratio, 1.55; 95% CI, 1.43-1.67; P < .0001), but not cancer-specific survival (hazard ratio, 1.11; 95% CI, 0.98-1.27; P = .099).Conclusions
Patients with breast cancer with preexisting CVD are less likely to receive recommended treatment for their cancer and more likely to exhibit worse overall survival. 相似文献16.

Background
As oral targeted agents, such as ibrutinib, become more widely used, understanding the impact of suboptimal dosing on overall survival (OS) and progression-free survival (PFS) outside of clinical trials is imperative.Patients and Methods
Data on ibrutinib discontinuation, dose reductions, and treatment interruptions were collected on 170 non-Hodgkin lymphoma and chronic lymphocytic leukemia (CLL; n = 115, 64%) patients treated with ibrutinib at a single institution. Ibrutinib dose adherence was calculated as the proportion of days in which ibrutinib was administered out of the total number of days ibrutinib was prescribed in the first 8 weeks. Kaplan-Meier curves and log-rank tests were used to compare conditional survival outcomes beyond 8 weeks in patients with ≥ 80% dose adherence and patients with < 80% dose adherence.Results
Median OS among those who discontinued therapy for progression was poor (n = 51, 1.7 months; 95% confidence interval, 0.3-3.7). Lower dose adherence (< 80%) was associated with significantly worse PFS (P = .002) and OS (P = .021). However, among CLL patients, lower dose adherence was only associated with worse PFS (P = .043). Patients with early dose reductions had significantly worse PFS (P = .004) and OS (P = .014). Patients with dose interruptions lasting > 1 week had worse PFS (P = .047) but not OS (P = .577).Conclusion
In this observational study, non-Hodgkin lymphoma and CLL patients experienced poor outcomes after discontinuing ibrutinib for disease progression. The inferior survival related to suboptimal dose adherence of ibrutinib was predominantly due to early dose reduction. These data confirm poor survival in CLL and lymphoma patients alike after ibrutinib discontinuation, and support recommendations for full dose at treatment initiation. 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
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19.
