Elderly patients are often considered as subjects at risk for bad tolerance to chemotherapy. They are therefore treated in a less aggressive way compared with younger women. In a retrospective study, we evaluated the dose-intensity of a chemotherapy for 15 patients older than 70 years of age, presenting an ovarian carcinoma. Median age was 73 years. All but one were classified in stage III-IV and only four were presented with a complete surgery or with a pathological residue < 2 cm. Six patients were considered as non operable. Performance status (PS) was in 11 cases equal to 0 or 1. The treatment associated from D1 to D4: carboplatine 75 mg/sqm/day, cyclophosphamide 250 mg/sqm/day, etoposide 50 mg/sqm/day for six cycles each over four weeks. We compared for each drug the delivered dose-intensity (DID) all along the six cycles to the forecast dose-intensity (FID). Except for the patients with a PS > or = 2, treated in first intention by a 2/3 dose, the DID/FID ratio was > 90%. It decreased between the 1st and 3rd cycles, then remained unchanged. Treatment was well tolerated by patients with a PS < 2 whose 4/11 have presented a grade III-IV hematologic toxicity. In return, despite the initial dose reduction, 3/4 patients with a PS > or = 2 had severe complications. There were no toxic deaths. Three patients only had a delay for reinduction. Three out of six non operables at first had a surgical second-look with possibility of residual masses cutting of (3 PRh). Four patients were alive in first CR at 18, 22, 23 and 28 months. Women older than 70 years with a good performance status presenting an ovarian carcinoma can be treated as younger women are. A chemotherapy using efficient drugs can be delivered with an acceptable toxicity and a high dose-intensity.
