Introduction And Objectives: Metastatic hormone-sensitive prostate cancer (mHSPC) accounts for 12% of prostate cancers diagnosed in Guadeloupe according to the Guadeloupean cancer registry. Most published studies have been conducted on the Caucasian population, whereas data concerning mHSPC in the Afro-Caribbean population are lacking. We aimed to describe the patient characteristics and estimate the progression-free survival of men with mHSPC in an Afro-Caribbean population according to the available treatment.

Patients And Methods: This was a monocentric retrospective study that consecutively included 133 men with mHSPC between January 1, 2015 and December 31, 2019 at the University Hospital of Guadeloupe. The primary endpoint was a description of the patients' characteristics with a description of complications at diagnosis. The secondary endpoint was progression-free survival. Kaplan-Meier survival and Cox proportional hazard analyses were performed.

Results: The median age at diagnosis was 71 years. The median prostate-specific antigen (PSA) was 147 ng/ml and 37% of patients presented with a disease-related complication at diagnosis. The survival analysis according to treatment showed median survival of 15 months for the androgen deprivation therapy (ADT) + chemotherapy group, 20 months for the ADT + new hormone therapy group, and 21.5 months for the ADT alone group, with no significant difference between the three therapeutic options (log-rank test: 0.27). In univariate analysis, none of the patient characteristics at diagnosis (i.e., age, PSA, bone lesions, visceral lesions) were significantly associated with the risk of progression, regardless of the treatment.

Conclusion: There was no significant difference in terms of progression-free survival between currently validated treatments administered in the first line, regardless of the tumor volume or risk group. Future studies with larger numbers of patients and involving molecular factors are required to confirm or invalidate these results and understand the evolution of prostate cancer in our population and thus better prevent complications related to the disease.

Biopsy Grade Group as a reliable prognostic factor for BCR in Afro-Caribbean men with intermediate- and high-risk prostate cancer.

World J Urol 2020 Jun 3;38(6):1493-1499. Epub 2019 Sep 3.

Service d'Urologie, CHU de Pointe-à-Pitre, 97159, Pointe-a-Pitre, France.

Purpose: The Grade Group (GG) classification is recommended by guidelines as a reliable prognostic factor of prostate cancer. However, most studies have been performed on the Caucasian population. Our objective was to validate GG classification as a safe way to classify intermediate- and high-risk patients with African ancestry.

Patients And Methods: This was a retrospective study in an Afro-Caribbean population. A total of 1236 patients were included between 2000 and 2015. Patients were stratified according to (GG). Survival analysis was performed using the Kaplan-Meier method, univariate and multivariate analyses using the Cox model.

Results: There was no significant difference at 5 and 10-year BCR-free survival between the intermediate- and high-risk groups, based on the D'Amico classification. There was a highly significant difference in BCR-free survival at 5 (p < 0.0001) and 10 years (p < 0.0001) for patients of GG 1 and 2 vs 3, 4, and 5, respectively. There was no significant difference in 5-year BCR-free survival of patients of GG grades 1 and 2, whether lymph-node dissection was performed or not. There was a significant difference between GG 2 and 3 patients in 5 (p = 0.008) and 10-year BCR-free survival (p = 0.01). High PSA (p < 0.0001), pathological GG ≥ 3 (p < 0.0001), pathological stage pT3 (p < 0.0001) and positive margins (p < 0.0001) were factors for BCR in multivariate analysis.

Conclusion: The GG 2015 classification appears to be a better prognostic factor than D'Amico classification for intermediate- and high-risk Afro-Caribbean patients.

Coronary events complicating infective endocarditis.

Heart 2017 12 22;103(23):1906-1910. Epub 2017 Jun 22.

Aix-Marseille Université, Marseille, France.

Objective: Acute coronary syndromes (ACS) are a rare complication of infective endocarditis (IE). Only case reports and small studies have been published to date. We report the largest series of ACS in IE. The aim of our study was to describe the incidence and mechanisms of ACS associated with IE, to assess their prognostic impact and to describe their management.

Methods: In a bicentre prospective observational cohort study, all patients with a definite diagnosis of IE were prospectively included. The incidence, mechanism and prognosis of patients with ACS were studied.

Results: Among 1210 consecutive patients with definite IE, 26 patients (2.2%) developed an ACS. Twenty-three patients (88%) had a coronary embolism. Two patients had coronary compression by an abscess or a pseudoaneurysm and one patient had an obstruction of his bioprosthesis and left coronary ostium by a large vegetation. Nineteen (73%) patients with ACS developed heart failure and this complication was 2.5 times more frequent than in patients without ACS (p<0.0001). In the ACS population, mortality rate was twice than the population without ACS.

Conclusions: ACS is a rare complication of IE but is associated with an increased risk of heart failure and high mortality rate.

Active Surveillance for Favorable Risk Prostate Cancer in African Caribbean Men: Results of a Prospective Study.

J Urol 2017 05 18;197(5):1229-1236. Epub 2016 Dec 18.

Department of Urology, Pointe-à-Pitre University Hospital, Pointe-à-Pitre, Guadeloupe, France; Institut national de la santé et de la recherche médicale, U1085-IRSET and Université des Antilles, Pointe-à-Pitre, Guadeloupe, France.

Purpose: Active surveillance is a treatment option for favorable risk prostate cancer. However, data are missing on populations of African descent. We evaluated the safety and benefit of active surveillance in an African Caribbean cohort with favorable risk prostate cancer.

Materials And Methods: Between 2005 and 2016, a single center, prospective cohort study was performed in Guadeloupe, French West Indies, including patients on active surveillance who had low risk prostate cancer (prostate specific antigen 10 ng/ml or less and Gleason score 6 or less) or favorable intermediate risk prostate cancer (prostate specific antigen 10 to 20 ng/ml, Gleason score 3 + 4 or less and life expectancy less than 10 years). Treatment was recommended in case of grade progression, increased tumor volume, prostate cancer doubling time less than 36 months or patient wish. Overall survival, disease specific survival and duration of active surveillance were calculated with the Kaplan-Meier method. Multivariate analysis was performed using the Cox proportional hazards model to identify predictors of active surveillance termination.

Results: A total of 234 patients with a median age of 64 years were enrolled in study. Median followup was 4 years (IQR 2.3-5.5). Overall survival at 30 months, 5 years and 10 years was 99.5%, 98.5% and 90.7%, respectively. Disease specific survival at 30 months, and 5 and 10 years was 100%. At 30 months, 5 years and 10 years 72.7%, 52.6% and 40.4% of patients, respectively, remained untreated and on active surveillance. Age (HR 0.96 per additional year, 95% CI 0.93-0.99) and prostate specific antigen density (HR 1.52 per additional 0.1 ng/ml, 95% CI 1.20-1.89) were found to be independent predictors of active surveillance termination.

Conclusions: Active surveillance is safe and beneficial for highly selected African Caribbean patients. It seems to be feasible for patients at low risk and intermediate favorable risk. Prostate specific antigen density could help better select these patients.
