Aims and Background: This report retrospectively analyzes 9 cases of e
pithelial ovarian cancer with persistent retroperitoneal metastasis af
ter intraperitoneal surgery (without systematic lymphadenectomy) and c
hemotherapy. !Methods: All 9 patients were diagnosed as FIGO stage I t
o IV at the time of primary surgery. They received combined postoperat
ive chemotherapy (8 cases with a cisplatin-based regimen and 1 with ad
riamycin and endoxan). They were submitted to pelvic and paraaortic ly
mphadenectomy at the National Cancer Institute of Milan during the per
iod 1990-1994. Results: All patients presented no evidence of disease
in the abdominal cavity but retroperitoneal metastasis, which was the
unique metastatic site. Chemotherapy was administered as adjuvant ther
apy after lymphadenectomy. Six patients were free of disease for 14 to
61 months. One patient with vaginal recurrence at the 18th month was
treated with radiotherapy and chemotherapy, but died of widespread dis
ease 25 months after lymphadenectomy. Two patients with massive positi
ve lymph nodes died of brain and lung metastasis 20 and 6 months later
, respectively. Conclusions: We conclude that retroperitoneal metastas
is may be the only site of persistent disease and that systematic lymp
hadenectomy technically feasible in this situation to increase the opp
ortunity for local disease control and to obtain a good result.
