ABSTRACT
PURPOSE:
In a retrospective analysis, our aim was to evaluate the immediate tolerance and the early and late complications of abdomino-pelvic radiotherapy in the Centre Alexis-Vautrin (France). PATIENTS ANDMETHODS:
From 1st January 1983 to 31st December 1993, 117 patients were treated at Centre Alexis Vautrin in Nancy for epithelial ovarian cancer by abdominal and/or pelvic irradiation after surgery. They were aged from 24 to 85 with a median of 56 years. There were ten patients with stage I (9%), 28 patients with stage II (24%), 60 patients with stage III (61%) and 19 patients with stage IV (16%) disease. Results of surgery were determined as follows satisfactory with absence of tumoral residuum in 26% cases (30 patients) and with residuum inferior to 20 mm in 46% cases (52 patients; incomplete in 26% cases (31 patients) either because of residuum superior in 20 mm and/or incomplete surgery; and not evaluable in 3% cases (four patients). Seventy-seven patients were sent to the Centre for postoperative treatment (66% patients of the series), 48 of them (62.4%) after non-satisfactory surgery, 29 after satisfactory surgery (37.6%). Chemotherapy was administered to only 104 patients (89% cases), and contained platinum salts and cyclophosphamid for 87% of these patients. Fourteen patients (12%) received a single irradiation dose after surgery three in stage I, three with poor evaluation of the disease in the initial stage, three with medical contraindications to chemotherapy treatment, six with contraindications due to advanced age (?? Makes 15 ). Histologically, 46% of patients had a serous adenocarcinoma, 9% a mucinous adenocarcinoma, 11% an endometrioid adenocarcinoma, 2% a clear cell adenocarcinoma, 1% an undifferentiated adenocarcinoma, and 31% an epithelial carcinoma without any other indication. The histological grade which was recently introduced was rarely indicated. Complementary radiotherapeutic treatment consisted of pelvic irradiation for 14 patients (12%), abdomino-pelvic irradiation for 63 patients (54%), and total abdominal irradiation with a pelvic boost for 40 patients (34%).RESULTS:
The immediate tolerance to irradiation can be considered as globally satisfactory since 9% of the patients (ten cases) had no problems and 64% of the patients developed a minor intolerance easily controlled by symptomatic treatments. There were also digestive complications nausea, vomiting and diarrhea for 66% of the patients (50 cases); to a lesser extent, 20% of the cases experienced associated digestive and hematological complications (15 patients); 9% isolated hematological troubles such as anemia (seven patients); 4% digestive complications (three patients) and 1% hematological and urinary digestive troubles (one patients). Late irradiation sequelae were evaluated for 89 patients with a follow-up lasting from 4 months to 11 years. Sixty-six patients had no sequelae, eleven patients had minor tolerability problems--mainly digestive for more than half of them. Five patients presented severe complications, including hematological problems such as chronic thrombopenia in two cases, urinary-problems in two other cases, and one patient presented with a case of histologically proven malabsorption. Two patients presented major problems; one case of radic cystitis and one of radic bowel. Two patients died of iatrogenic causes one of induced leukemia, the other of treatment-induced digestive and renal complications. The overall survival rate was 30% at 5 years and 22% at 10 years. It was 90% at 5 and 10 years for stage I patients, 60% at 5 years and 30% at 10 years for stage II patients, 22% at 5 years and 8% at 10 years for stage III patients, and finally 10% at 5 years for stage IV patients.CONCLUSION:
In this retrospective analysis of 117 epithelial ovarian cancers, treated over 10 years and which all received pelvic and/or abdominal irradiation, we can conclude that this treatment is globally well tolerated and that it yields a
