Adjuvant treatment and analysis of failures in patients with high-risk FIGO Stage Ib-II endometrial cancer: an Italian multicenter retrospective study (CTF study).

OBJECTIVES: The purpose of this retrospective study was to assess the clinical outcome of patients with high-risk, early-stage endometrioid endometrial cancer (stage Ib or II with myometrial invasion >50%, grade 2-3). METHODS: We assessed 192 patients who underwent hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy, had histologically negative pelvic nodes, and had negative CT findings for aortic node involvement. RESULTS: Tumor relapsed in 36 patients after a median time of 21.2 months. The recurrence was vaginal in 7 (19.4%), distant in 16 (44.4%), aortic in 8 (22.2%), and involved multiple sites in 5 (13.9%). There was a trend to a lower vaginal recurrence rate in the 143 patients who received adjuvant radiotherapy (+chemotherapy) compared with the 46 who did not (2.1% versus 8.7%). Distant or aortic recurrences were lower in the 37 patients who received adjuvant chemotherapy (+radiotherapy) than in the 152 who did not (2.7% versus 18.4%, p=0.02). Of the 29 patients who received sequential adjuvant chemotherapy and radiotherapy, none developed local recurrence and only one had distant recurrence. There was a trend for a better 5-year progression-free survival and overall survival for the patients who received chemotherapy (+radiotherapy) compared with those who did not (86.0% versus 71.3%, and 92.3% versus 75.6%, respectively). CONCLUSIONS: Our data appear to suggest that adjuvant chemotherapy reduces the risk of distant or aortic recurrences and that sequential adjuvant chemotherapy and radiotherapy achieve an excellent local and distant control of disease in these clinical settings.

Possible role of palliative surgery for bowel obstruction in advanced ovarian cancer patients.

OBJECTIVES: Bowel obstruction is a relatively common event (30-40%) in advanced or recurrent ovarian cancer patients. No definitive data are available on the optimal management of this serious complication and treatment is generally limited to adoption of palliative measures. These modalities include both surgical and medical procedures. The aim of this study was to define selection criteria for subjects who would benefit from palliative surgery. STUDY DESIGN: Out of 270 epithelial ovarian cancer patients treated in the period 1984-2005, 75 (28%) developed bowel obstruction related to progression/recurrence of the disease. Palliative treatment - both medical and surgical - was applied on an individual basis. A new score developed by these authors was retrospectivelly applied to this group of patients with the aim of defining a subgroup that could benefit from surgical treatment. RESULTS: Fifty cases (66.7%) were medically treated whereas 25 patients (33.3%) underwent surgery. Mean and median survival rates were 34 and 28 weeks in the surgical group versus 12 and four weeks in the medical group. Distribution according to score showed 53 cases (71%) in the low score group (< 14) and 22 (29%) in the high score group (> 14). A significantly better survival was observed in the low-score group (p < 0.0001) and in the surgically treated patients (p < 0.001). According to the risk score variables patients treated surgically for obstruction with low scores had a longer survival (p < 0.005) compared to medical treatment but this difference was not found in the high-risk group (p < 0.05). CONCLUSIONS: The prognosis of patients with bowel obstruction in relation to advanced ovarian cancer is best determined by comprehensive assessment of all prognostic parameters to define a subgroup of patients in a low-risk group that may benefit from surgical treatment.
