Health-related quality of life in men with prostate cancer undergoing active surveillance versus radical prostatectomy, external-beam radiotherapy, prostate brachytherapy and reference population: a cross-sectional study.

BACKGROUND: The purpose of this study is to describe Health-Related Quality of Life (HRQoL) of localized prostate cancer patients in an Active Surveillance (AS) program, and to compare them with those undergoing radical prostatectomy (RP), external-beam radiotherapy (XRT) and brachytherapy (BT). METHODS: Multi-institutional pooled cross-sectional analysis on patients in an AS protocol: < 75 years old; pathologically confirmed LPC (maximum of three positive cylinders); Gleason score < 3 + 4; clinical stage T1a-T2b; and PSA < 15 ng/ml. Exclusion criteria for this study were: less than 6 months in AS, termination of AS protocol, or incomplete data. Patients in AS were matched with those treated with RP, XRT or BT from the 'Spanish Multicentric Study of Clinically Localized Prostate Cancer' cohort according to risk group, time from treatment selection to HRQoL survey, and age. Prostate-specific (EPIC) and generic (SF-36) HRQoL instruments were completed. Analysis was stratified by HRQoL survey moment (>or < 2.5 years from treatment selection), and age (>or < 70 years old). RESULTS: Median of time from treatment selection to HRQoL survey in the total 396 patients (99 per treatment group) was 2.4 years (range 0.5-8.3). Patients in AS presented higher (better) urinary incontinence scores than RP ones in both stratus of time from treatment selection to HRQoL survey (92.6 vs 67.0 and 81.4 vs 64.4, p <  0.01). Patients in AS for < 2.5 years presented greater sexual scores than any active treatment (p <  0.01), but only statistically higher than RP for those in AS for longer than 2.5 years. The magnitude of the differences between AS and RP groups in both EPIC domains ranged from moderate (0.7 SD) to large (1.0 SD). Regardless of treatment applied, patients presented similar and slightly increased SF-36 scores than US general population reference norms. Nonetheless, patients in AS for < 2.5 years reported worse outcomes than other treatment groups on physical health domains, especially in bodily pain (0.5-0.6 SD), and vitality (0.6-0.8 SD). CONCLUSIONS: Considering patients' well-being, AS can be a good therapeutic option due to the low impact caused on urinary continence and sexual function. However, longitudinal studies are required to take into account HRQoL evolution over time.

Concomitant CIS on TURBT does not impact oncological outcomes in patients treated with neoadjuvant or induction chemotherapy followed by radical cystectomy.

BACKGROUND: Cisplatin-based neoadjuvant chemotherapy (NAC) for muscle invasive bladder cancer improves all-cause and cancer specific survival. We aimed to evaluate whether the detection of carcinoma in situ (CIS) at the time of initial transurethral resection of bladder tumor (TURBT) has an oncological impact on the response to NAC prior to radical cystectomy. PATIENTS AND METHODS: Patients were identified retrospectively from 19 centers who received at least three cycles of NAC or induction chemotherapy for cT2-T4aN0-3M0 urothelial carcinoma of the bladder followed by radical cystectomy between 2000 and 2013. The primary and secondary outcomes were pathological response and overall survival, respectively. Multivariable analysis was performed to determine the independent predictive value of CIS on these outcomes. RESULTS: Of 1213 patients included in the analysis, 21.8% had concomitant CIS. Baseline clinical and pathologic characteristics of the 'CIS' versus 'no-CIS' groups were similar. The pathological response did not differ between the two arms when response was defined as pT0N0 (17.9% with CIS vs 21.9% without CIS; p = 0.16) which may indicate that patients with CIS may be less sensitive to NAC or ≤ pT1N0 (42.8% with CIS vs 37.8% without CIS; p = 0.15). On Cox regression model for overall survival for the cN0 cohort, the presence of CIS was not associated with survival (HR 0.86 (95% CI 0.63-1.18; p = 0.35). The presence of LVI (HR 1.41, 95% CI 1.01-1.96; p = 0.04), hydronephrosis (HR 1.63, 95% CI 1.23-2.16; p = 0.001) and use of chemotherapy other than ddMVAC (HR 0.57, 95% CI 0.34-0.94; p = 0.03) were associated with shorter overall survival. For the whole cohort, the presence of CIS was also not associated with survival (HR 1.05 (95% CI 0.82-1.35; p = 0.70). CONCLUSION: In this multicenter, real-world cohort, CIS status at TURBT did not affect pathologic response to neoadjuvant or induction chemotherapy. This study is limited by its retrospective nature as well as variability in chemotherapy regimens and surveillance regimens.

European temporal trends in the use of lymph node dissection in patients with renal cancer.

BACKGROUND: The role of lymph node dissection (LND) in renal cell carcinoma (RCC) is still under debate. We aimed to assess the utilization rates of LND over time in Europe. METHODS: A multi-institutional database of 13,581 RCC patients who underwent radical nephrectomy (RN) or nephron sparing surgery (NSS) between 1988 and 2014 was created within an European consortium. We analysed temporal trends in the frequency of LND by using Joinpoint regression. Logistic regression models were used to identify predictors of LND. RESULTS: Overall, 5114 patients (42.7%) underwent LND. Lymph node invasion was recorded in 566 cases (11% of LND patients) which represents 4.7% of the whole study cohort. A gradual decline in the use of LND started in the 1990s. After 2008 LND decreased significantly by 21.5% per year (95%CI -33.3 to -7.5, p < 0.01) until 2011 and stabilized thereafter (Annual Percentage Change 4.9%, 95%CI -3.4 to 13.8, p = 0.2). At multivariable analyses, patient age (OR 0.98, p < 0.0001), type of surgery (RN vs. NSS: OR 5.46, p < 0.0001), surgical approach (open vs. minimally invasive: OR 1.75, p < 0.0001), T stage (T2 vs. T1: OR 1.57; T3-4 vs. T1: OR 1.44, p < 0.0001), clinical tumour size (OR 1.14, p < 0.0001), and year of surgery (OR 0.95, p < 0.0001) were associated with higher probability of LND at nephrectomy. CONCLUSIONS: A trend towards lower LND was observed over time for RCC patients who underwent RN or NSS. LND is more frequently performed in younger patients, locally advanced diseases and in case of open surgery.

Active surveillance for low-risk prostate cancer in African American men: a multi-institutional experience.

OBJECTIVE: To compare the outcomes of active surveillance (AS) series between African American men (AAM) and non-AAM diagnosed with low-risk prostate cancer at 3 medical centers. METHODS: Between 2005 and 2012, 214 men accepted AS on the basis of favorable clinical features and parameters after initial and repeat biopsy. Failure was defined as increase in Gleason score >6, total positive cores >33%, maximum cancer volume in any core >50%, or a prostate-specific antigen >10 ng/mL. Disease progression and overall AS failure were compared between the 2 groups. RESULTS: Of 214 men, 75 were excluded, leaving 67 AAM and 72 non-AAM on AS. Median age at diagnosis was 64 and 67 years for AAM and non-AAM, respectively, and median follow-up was 34 and 46 months, respectively. During this time, 44 AAM (66%) remained on AS, and 23 (34%) underwent treatment, of whom 6 (26%) were treated by patient choice and 17 (74%) because of disease progression. In the non-AAM group, 59 (82%) men remained on AS, and 13 (18%) underwent treatment, 8 (62%) were treated by patient choice and 5 (38%) because of disease progression. The 3-year freedom from overall treatment was 74% and did not differ by race (P = .06). The 3-year freedom from disease progression was 85%, where AAM were at significantly higher risk of disease progression (hazard ratio = 3.8; 95% confidence interval: 1.4-10.4; P = .01). CONCLUSION: Our study suggests a higher disease progression rate in AAM who choose AS for low-risk prostate cancer compared with non-AAM, signifying a potential need for closer follow-up and more stringent enrollment criteria in AAM.
