RESUMO
BACKGROUND: Cooperation in public health and in oncology in particular, is currently a major issue for the island of Martinique, given its geopolitical position in the Caribbean region. The region of Martinique shares certain public health problems with other countries of the Caribbean, notably in terms of diagnostic and therapeutic management of patients with cancer. We present here a roadmap of cooperation priorities and activities in cancer surveillance and oncology in Martinique. MAIN BODY: The fight against cancer is a key public health priority that features high on the regional health policy for Martinique. In the face of these specific epidemiological conditions, Martinique needs to engage in medical cooperation in the field of oncology within the Caribbean, to improve skills and knowledge in this field, and to promote the creation of bilateral relations that will help to improve cancer management in an international healthcare environment. CONCLUSIONS: These collaborative exchanges will continue throughout 2020 and will lead to the implementation of mutual research projects across a larger population basin, integrating e-health approaches and epidemiological e-cohorts.

Once his specialty has been chosen, and according to his ranking, the new resident in oncology decides on the subdivision in which he wishes to be among the 28 existing subdivisions. Two concern overseas departments and territories: the Antilles-Guyana subdivision and the Indian Ocean subdivision. The oncology residency has its own particularities because of the demographic characteristics and epidemiology of cancers in these areas, but also because of a particular organization of care and university teaching. The training of residents in these subdivisions is little known. Over the past ten years, most of the residents have been trained in oncology-radiotherapy in these subdivisions and some of them in medical oncology. The residency program is however experiencing a revival in terms of university education in parallel with the development of technical and human equipment in the centres of these regions. This article details the training of residents in oncology in French overseas territories by contextualizing it with epidemiological data and the characteristics of the oncology care offer in these territories.

To describe survival according to prognostic factors of women with breast cancer in French overseas territory (Martinique) during 2008-2017. We performed a Cox model for prognostic factors for OS in breast cancer patients. The cut-off date for the analysis was 13/10/2018. The main factors were demographic data, stage, hormone receptors (HR) status and HER2 status. Curves were compared with the log rank test to select candidate variables for the multivariate analysis. We included 1,708 patients; median age at diagnosis was 57 years. Triple negative breast cancer (TNBC) accounted for 20.9% (n = 332). Among the patients, 72.3% (n = 1015) had localised or local spread cancer. One-year OS was 95.2% and was 80.1% at 5 years. In TNBC, 1-year-survival was 90.4%, which fell to 70.1% at 5 years. Patients with metastatic disease at diagnosis had 1-year-survival of 74.5%, and 20.1% at 5 years. Multivariate analysis by Cox regression identified 4 factors significantly associated with an increased risk of death: metastatic disease at diagnosis (hazard ratio (HR) = 15, p<0.0001), TNBC (HR 2.84, p<0.0001), HR+/HER2- status (HR 2.05, p<0.0084) and age >75 years (HR 3.8, p<0.0001). This is the first study performed on breast cancer survival in Martinique. Our findings show that breast cancer has overall good prognosis in patients and also how prognosis factors are distributed in the population.

Image-guided adaptive brachytherapy (IGABT) is part of the standard of care for locally advanced cervical cancer (LACC). Access to IGABT is limited in many regions, thus leading to treatment care disparities. We report the experience of a referral network for women with LACC between radiotherapy facilities in Overseas France and Gustave Roussy. This is a retrospective review of patients with LACC referred to Gustave Roussy, for pulsed-dose-rate (PDR) image-guided adaptive BT after initial radiation therapy in the French overseas between 2014 and 2021. Sixty-four patients were eligible to receive IGABT. Overall treatment time (OTT) was 60.5 days (IQR: 51−68.5). The median follow-up time was 17 months. At two years, estimated probabilities of LC, progression-free survival, and overall survival (OS) were 94.6% (95% CI: 88.9−100.0%), 72.7% (95% CI: 61.1−86.5%), and 82.5% (95% CI: 72.0−94.5%). In multivariable analysis, a D90CTVHR < 85GyEQD2 and a CTVHR volume > 40 cm3 were significant for poorer PFS (p = 0.001 and p = 0.009, respectively) and poorer OS (p = 0.004 and p = 0.004). The centralization of this advanced technique to expert centers requires a well-defined workflow and appropriate dimensioning of resources to minimize OTT.
RESUMO
BACKGROUND: Enzalutamide, a major antiandrogen indicated for metastatic castration-resistant prostate cancer, has worrisome toxicities in aging patients. Dose reduction might limit toxicity, but potential loss of efficacy is a concern. We compare up-front low-dose versus standard-dose enzalutamide. PATIENTS AND METHODS: Records of prostate cancer patients receiving enzalutamide were retrospectively retrieved. Selection criteria were: age ≥ 75, metastatic disease, surgical or medical castration, and rising prostate-specific antigen (PSA). Data were excluded of those missing follow-up PSA values. Low-dose enzalutamide (≤ 80 mg per day) was compared to standard dose (160 mg per day). Progression-free survival analyzed the time from start of enzalutamide to event, defined as ≥ 25% and ≥ 2 ng/mL PSA increase above nadir, or death from any cause. RESULTS: Fifty-nine patients were identified, of whom 16 received low-dose and 43 standard-dose therapy. Patients in the low-dose group were significantly old, with a median (range) age of 84.6 (74.9-93.8) years; median (range) PSA at start of enzalutamide was 59.2 (11.0-1058.3) ng/mL; 11 had bone metastases only, 2 metastatic lymph nodes only, and 3 bone and lymph node localizations. Pain score was > 3/10 in 4 patients (27%), Eastern Cooperative Oncology Group performance status was ≥ 2 in 9 (56%); 3 patients had received prior abiraterone and 3 bicalutamide. None received chemotherapy. PSA decrease of ≥ 50% at 12 weeks was observed in 67% patients (10/15), versus 45.0% with standard dose. Median (range) PSA at last follow-up was 1.6 (0-599.3) ng/mL. Median progression-free survival was 11.2 months, versus 11.9 months for patients receiving the standard dose (P = .612). CONCLUSION: Low-dose enzalutamide in very old, symptomatic, poor-performance patients with metastatic disease was associated with high response rate and survival comparable to standard dose.

AIM: To investigate rates of distant metastases (DM) detected with [18]fluorodeoxyglucose-positron emission tomography/computed tomography (18FDG-PET/CT) in early stage invasive breast cancer. METHODS: We searched the English language literature databases of PubMed, EMBASE, ISI Web of Knowledge, Web of Science and Google Scholar, for publications on DM detected in patients who had 18FDG-PET/CT scans as part of the staging for early stages of breast cancer (stage I and II), prior to or immediately following surgery. Reports published between 2011 and 2017 were considered. The systematic review was conducted according to the PRISMA guidelines. RESULTS: Among the 18 total studies included in the analysis, the risk of DM ranged from 0% to 8.3% and 0% to 12.9% for stage I and II invasive breast cancer, respectively. Among the patients with clinical stage II, the rate of occult metastases diagnosed by 18FDG-PET/CT was 7.2% (range, 0%-19.6%) for stage IIA and 15.8% (range, 0%-40.8%) for stage IIB. In young patients (< 40-year-old), 18FDG-PET/CT demonstrated a higher prevalence of DM at the time of diagnosis for those with aggressive histology (i.e., triple-negative receptors and poorly differentiated grade). CONCLUSION: Young patients with poorly differentiated tumors and stage IIB triple-negative breast cancer may benefit from 18FDG-PET/CT at initial staging to detect occult DM prior to surgery.
