Poor outcome of elderly patients with platinum-sensitive recurrent ovarian cancer: results from the SOCRATES retrospective study.

BACKGROUND: Elderly patients with ovarian carcinoma have a poorer prognosis compared with their younger counterpart, and this depends in most cases on undertreatment. The aim of this study was to evaluate, retrospectively, the pattern of care and the prognosis of elderly patients with platinum-sensitive recurrent ovarian cancer. The SOCRATES study retrospectively assessed the pattern of care of a cohort of patients with recurrent platinum-sensitive ovarian cancer observed in the years 2000-2002 in 37 Italian centres. Data were collected between April and September 2005. PATIENTS AND METHODS: Patients with recurrent ovarian cancer with >6 months of platinum free interval were considered eligible. Four-hundred-ninety-three patient files were collected and 425 were considered eligible and analyzed. Ninety-four patients with age >or=70 years and 331 patients with age <70 years were analyzed. RESULTS: Recurrence free interval (RFI), PS, and number of disease sites were similar among the two groups. A lower proportion of elderly patients underwent secondary cytoreduction (8.9% compared to 23.9%; p=0.0018). The mean number of chemotherapy lines received for recurrence was 2.7 and 2.5 in young and aged patients, respectively. Elderly patients received more frequently at second line single agent platinum than platinum-combination therapy or other non-platinum chemotherapy. The response rate to the second line chemotherapy was higher in younger patients than in the elderly population (CR+PR, younger: 67.2%; elderly: 46.5%; p=0.0004). Median overall survival from recurrence was 30.7 months in the younger patients and 23.6 months in the elderly group (p=0.0037). At multivariate analysis, number of disease sites (>1 vs. 1), performance status at recurrence (2-3 vs. 0-1), RFI (6-12 months vs. >12 months), age at recurrence, were independently associated with survival. CONCLUSION: Elderly patients with platinum-sensitive recurrent ovarian cancer receive less surgery and chemotherapy. Response to chemotherapy is better in younger patients. Age is an unfavourable factor independently associated to a worst prognosis.

Activity of chemotherapy in mucinous ovarian cancer with a recurrence free interval of more than 6 months: results from the SOCRATES retrospective study.

BACKGROUND: Mucinous ovarian carcinoma have a poorer prognosis compared with other histological subtypes. The aim of this study was to evaluate, retrospectively, the activity of chemotherapy in patients with platinum sensitive recurrent mucinous ovarian cancer. METHODS: The SOCRATES study retrospectively assessed the pattern of care of a cohort of patients with recurrent platinum-sensitive ovarian cancer observed in the years 2000-2002 in 37 Italian centres. Data were collected between April and September 2005. Patients with recurrent ovarian cancer with > 6 months of platinum free interval were considered eligible. RESULTS: Twenty patients with mucinous histotype and 388 patients with other histotypes were analyzed. At baseline, mucinous tumours differed from the others for an higher number of patients with lower tumor grading (p = 0.0056) and less advanced FIGO stage (p = 0.025). At time of recurrence, a statistically significant difference was found in performance status (worse in mucinous, p = 0.024). About 20% of patients underwent secondary cytoreduction in both groups, but a lower number of patients were optimally debulked in the mucinous group (p = 0.03). Patients with mucinous cancer received more frequently single agent platinum than platinum based-combination therapy or other non-platinum schedules as second line therapy (p = 0.026), with a response rate lower than in non-mucinous group (36.4% vs 62.6%, respectively, p = 0.04). Median time to progression and overall survival were worse for mucinous ovarian cancer. Finally, mucinous cancer received a lower number of chemotherapy lines (p = 0.0023). CONCLUSION: This analysis shows that platinum sensitive mucinous ovarian cancer has a poor response to chemotherapy. Studies dedicated to this histological subgroup are needed.
