RESUMO

INTRODUCTION: High-intensity focused ultrasound (HIFU) has proved to be effective in the treatment of localized prostate cancer. The aim of this prospective study is to assess their first oncological and functional results in an Afro-Caribbean population. METHODS: From May 2018 to January 2020, 77 patients issued from French West Indies were included. Several treatments were carried out: whole-gland treatment hemi or focal ablation; in a primary setting (group I) or a salvage therapy (group II). PSA level was assessed at 2, 6, 9 and 12 months. MpMRI and post HIFU biopsy were performed between 6 and 9 months postoperatively. Continence, urinary end erectile functions were assessed by ICS, IPSS and IIEF scores. RESULTS: Groupe I included 71.2% patients, group II, 28.8%. The median age was 75.4 years [IQR 69.6-79.4]. The median follow-up was 8.3 months [IQR 3.5-12.25]. At inclusion, PSA was 7.7ng/ml [IQR 5.5-11.2] in group I, and 5.9ng/ml [IQR 4.4-7.9] in group II. In the whole population, there was 73.5% negative biopsies; 14.7% of the biopsies were positive in treated zone and 11.8% in non-treated zone. Regarding morbidities, urinary incontinence appeared in 7.5% and erectile dysfunction rate was 13.2%. CONCLUSION: Our study reveals the first experience of HIFU by Focal One® device in an Afro-Caribbean population. It seems to be a safe and reproducible treatment with acceptable oncological results and low genitourinary morbidity. Long term follow-up and a higher number of patients are necessary to validate these results.

RESUMO

BACKGROUND: Prostate cancer is supposedly more aggressive among Afro-Caribbean men. There is a lack of data in this population for active surveillance. Published series are retrospective or have small samples and results are discordant. The objective was to determinate whether actual active surveillance modalities can be applied for Afro-Caribbean men by comparing their oncological outcomes with Caucasian men. METHODS: A total of 449 consecutive patients who underwent active surveillance for favorable-risk prostate cancer in two French University-Medical-Centers between 2005 and 2018: 261 in Guadeloupe, French West Indies, and 188 in Bordeaux, metropolitan France. Median follow-up was 56 months, (95% CI [32-81]) and 52 months (95% CI [30-75]), respectively (P=0.07). Curative treatment was given in case of histological, biological, or imaging progression, or upon patient demand. Primary endpoints were treatment-free, overall and specific survival. Secondary outcomes were reasons of discontinuating active surveillance, histological poor prognosis factors after prostatectomy, CAPRA-S score, biochemical-recurrence-free after treatment and metastasis-free survival. Kaplan-Meier method was used. RESULTS: Median treatment free survival was 58.4 months (CI 95% [48.6-83.1]) for ACM and not reached at 120 months for CM (P=0.002). Overall survival (P=0.53), and specific survival (P=0.21) were similar in the two groups. CM were likely to have poor prognosis factor on prostatecomy piece (57 vs 30%, P=0.01). No difference for repartition of the CAPRA-S score (P=0.86), biochemical-recurrence-free (P=0.92) and metastasis-free (P=0.44) survival. CONCLUSIONS: Oncological outcomes for active surveillance of Afro-Caribbean and Caucasian men were similar in terms of mortality, recurrence and metastasis in our bicentric study, showing usability of current criteria for Afro-Caribbean. The higher rate of disease progression in the Afro-Caribbean population requires close monitoring. LEVEL OF EVIDENCE: 3.

RESUMO

INTRODUCTION: Anthropometric data report that pelvic bone of African subjects are narrower and the pelvic cavity is deeper. The aim of the study was to evaluate the influence of pelvic dimensions (PD) on Positive surgical margins (PSM) rate in Afro-Caribbean population after robot-assisted laparoscopic prostatectomy (RALP). PATIENTS AND METHODS: Preoperative pelvic MRI of all patients who have had RALP at the University Hospital Center of Guadeloupe between January 2013 and December 2015 was retrospectively analyzed. PD, including the Height of the upper edge of the prostate (HP), the Apical Depth (AD) and Ischial Spines Distance (ISD), and indexes (prostate volumetric index [ISD/VP], apical depth index [ISD/AD] and prostate depth index [ISD/(AD/HP)]) were compared according to the presence or absence of PSM with uni and multivariate analysis. RESULTS: One hundred and seventy-eight patients were included in the study, of whom 60 (33.7%) presented PSM. In univariate analysis, significant differences between the presence or absence of PSM were observed on the AD (30.3±8.7mm versus 24.8±8.0mm, P<0.001), the HP (9.5±8.5mm versus 16.8±11.9mm, P<0.001) and the ISD (89.6±8.8mm versus 96.1±8.4mm) as well as the indexes of apical depth and prostatic depth. In multivariate logistic regression, the ISD (P<0.001) and HP (P=0.02) were associated with increased likelihood of PSM, but not AD or indexes. CONCLUSION: This study suggests that interspinous distance is the best predictor of PSM during RALP in Afro-Caribbean patients. This measure may be useful to define the therapeutic pattern of patients with prostate cancer. A prospective study with a larger population, comparing RALP in Afro-Caribbean and in caucasians patients, would be needed.

RESUMO

PURPOSE: Research of predictive factors of biochemical recurrence to guide the establishment of an adjuvant treatment after radical prostatectomy for cancer with positive surgical margins. METHODOLOGY: A retrospective cohort of 1577 afro-caribbean patients undergoing radical prostatectomy operated between 1st January 2000 and 1st July 2013 was analyzed. In this cohort, 406 patients had positive surgical margin, we excluded 11 patients who received adjuvant therapy (radiotherapy, hormonotherapy, radio-hormonotherapy) and 2 patients for whom histological analysis of the surgical specimen was for a pT4 pathological stage. After a descriptive analysis, we used a Cox model to look for predictors of survival without biochemical recurrence then, depending on the significant variables, we separated our population into six groups: stage pT2 with Gleason score≤3+4 (group 1), stage pT2 with a score of Gleason≥4+3 (group 2), stage pT3a with a Gleason core≤3+4 (group 3), pT3a stage with a score of Gleason≥4+3 (group 4), stage pT3b with a Gleason score≤3+4 (group 5) and stage pT3b Gleason≥with a score of 4+3 (group 6) and compared survival without biochemical recurrence using a log rank test. After radical prostatectomy with surgical margins with an anatomopathological stage≤pT3b, a Gleason score≥4+3 had a pejorative survival without biochemical recurrence than pathological stage (P<0.001). RESULTS: In multivariate analysis, predictors of survival without biochemical recurrence after radical prostatectomy with positive surgical margins were the majority Gleason postoperative (P<0.0001), pathological stage (P=0.049) adjusted preoperative PSA (P=0.826), with the body mass index (BMI) (P=0.59) and tumor volume (P=0.95). CONCLUSION: A high postoperatively Gleason score (≥4+3) has a better predictive value of biochemical recurrence than pathological stage pT2 or pT3 at the patients having been treated for prostate cancer by radical prostatectomy with positive surgical margins. LEVEL OF EVIDENCE: 4.

RESUMO

OBJECTIVES: Study the interest of addition of PSA density (PSAD), to the selection criteria of the French protocol for inclusion patients Afro-Caribbean on active surveillance prostate cancer. METHODS: A retrospective analysis of 1505 patients who had, in turn, a radical prostatectomy for cancer between 2000 and 2012, in a single reference center. One hundred and forty-one patients was eligible, at the time of their diagnosis, for active surveillance by the criteria of the French protocol. This population was divided into 2 groups according to the histological analysis of the prostatectomy specimen confirmed indolent cancer or overturned. The median PSAD of each group was calculated to be compared. Secondarily, the most discriminating PSAD was investigated by the method of ROC after constitution tables intrinsic validity in this population. This threshold has secondary conducting a comparative analysis of the underestimation of cancer in terms of aggressiveness and/or extension between patients selected according to the criteria of the French protocol and "on-selected" patients according to these criteria and their PSAD. RESULTS: Of the 141 patients identified for analysis, histological examination of the prostatectomy specimen has to show that 42 patients (29.7 %) were actually more aggressive cancer (20.6 % of Gleason ≥ 7), wider (4.2 % ≥ pT3) or larger and more aggressive (4.9 %) than foreshadowed criteria French protocol. The median PSAD these 42 patients were significantly higher than the median PSAD patients correctly estimated (0.18 vs. 0.14, p-value=0.046). The application of the most discriminating threshold: 0.15 ng/ml/cm(3) in this population allowed to significantly improve the selection of candidates of the 79 "on-selected" patients, six (20.2 %) were actually more aggressive cancer (13.9 % of Gleason ≥ 7), wider (2.5 % ≥ pT3) or larger and more aggressive (3.8 %). CONCLUSION: The criteria for the French protocol for active surveillance, applied to the Caribbean population underestimate 29 % of non-latent cancers. Adjuvants criteria that must be inexpensive, sensitive and specific seem necessary in this population. A PSAD<0.15 ng/ml/cm(3) could be one of these criteria.

RESUMO

OBJECTIVES: To study clinical characteristics, in terms of survival and response to treatment, of patients with non-localized prostate cancer at diagnosis in an Afro-Caribbean population from Guadeloupe. METHODS: Cases of stage IV prostate cancer (T4N0M0, TxN1M0 and TxNxM1) at diagnosis in the Pointe à Pitre Hospital were selected from 1995 to 2012 and studied. RESULTS: One hundred and eighty-three patients were included. Median age at diagnosis was 70.3 years old (79.2% were more than 65 years). A total of 81.5% of them was TxNxM1 and 11.5% was TxN1M0. Median disease free survival was 18.5 months. Median overall survival was 49.0 months. CONCLUSION: This study about non-localized prostate cancer at diagnosis in an Afro-Caribbean population from a French Caribbean archipelago seemed to show no difference with general population suffering from the same disease, although prostate cancer incidence in this area is one of the highest in the world.
