Curative 3D Conformal Radiotherapy of Non-Operated Prostate Adenocarcinoma at Pointe-a-Pitre University Hospital (Guadeloupe): About 29 Cases

Context: Technological advances have improved the toxicities of radiotherapy. We are evaluating the 3D technique in prostate cancer. Materials and Methods: Retrospective study from January 2015 to December 2015 with 29 files. Survival was calculated by Kaplan-Meier method. Results: We collected 29 patient records over the study period. The median age was 75 years with the following extremes: 54 years and 83 years. The median PSA level was 12 ng/ml with a range of 3.05 to 79 ng/ml. Gleason score analysis showed 6 patients (20.69%) with a score of 6 (3 + 3), 23 patients (79.31%) with a score of 7 including 12 patients (41.38%) with grade 3 and 11 patients (37.93%) with grade 4. The median dose delivered was 74 Gy, with a mean dose of 73.79 Gy and extremes of 70 Gy for the minimum and 76 Gy for the maximum. Hormone therapy was combined with radiotherapy in 17 patients (58.62%). Seven patients (24.14%) had grade 1 acute bladder toxicity and one patient (3.45%) had grade 2 acute toxicity. Late bladder toxicity was grade 1 in 5 patients (17.24%), grade 2 in 3 patients (10.34%) and grade 3 in 1 patient (3.45%). Late rectal toxicity, grade 2 in 3 patients (10.34%), grade 3 in 1 patient, was noted. Overall survival at 2 years was 100% and 89.65% at 5 years. Relapse-free survival at 2 years was 82.76% and 62.07% at 5 years. There were 3 deaths (10.34%) of which only one was related to prostate cancer. Conclusion: Radiotherapy, like surgery, is a fundamental option for the treatment of prostate cancers, particularly those that are locally advanced. It is gaining in importance with the improvement of techniques (IMRT, VMAT…) and new fractionations which contribute to the reduction of toxicities and the comfort of patients (shorter spread).

Gastric Adenocarcinoma at the Joliot Curie Institute in Dakar: Epidemiological, Diagnostic and Therapeutic Aspects about 54 Cases

Objectives: To study the epidemiological, diagnostic, therapeutic and prognostic aspects of gastric adenocarcinoma at the Joliot Curie Institute in Dakar. Materials and Methods: We conducted a retrospective study over a seven-year period from January 2010 to December 2017 at the Joliot Curie Institute in Dakar. All cases of gastric adenocarcinoma proven by fibroscopy followed by histology or proven on the histological analysis of a surgical specimen were taken into account. The parameters studied were age, risk factors, stages of the disease, treatment and prognosis. Results: There were 54 cases of gastric adenocarcinoma over a period of 7 years. The average age was 54.74 years with extremes of 25 and 84 years. A male predominance was noted (35/54). The main risk factors found were alcohol (5/54), tobacco (13/54), Helicobacter pilori (4/54), gastric ulcer (12/54). Epigastralgia was the most frequent clinical manifestation. FOGD was carried out in 77.8% of patients. Histology was obtained before surgery in 40 patients (74.1% of cases) and on the operating room in 14 patients (25.9%). Patients were classified as stage II in 2/54 cases, stage III in 5/54 cases and stage IV in 47/54 cases. Gastro-entero-anastomosis was the main surgical procedure performed. External radiotherapy was performed in 1/54 patients. Chemotherapy was done in 52/54 patients, 96.3% of the cases. It was palliative in 66.7% of cases, neoadjuvant in 1.9% of cases, adjuvant in 24.1% of cases, perioperative in 3.7% of cases. Mortality was 79.6%. Patient survival times were relatively short: in less than 6 months 24/54 cases, 13/54 cases between 6 - 12 months, 5/54 cases between 13 - 24 months and 6/54 cases beyond 24 months. 6/54 patients were lost from view. Conclusion: Gastric adenocarcinoma is diagnosed lately in our conditions. It is responsible for a high mortality rate. Palliative treatment is often the only option because of the delay in diagnosis.
