ABSTRACT
BACKGROUND: Ascites secondary to malignancy is a major cause of recurring morbidity in patients with ovarian cancer. In patients previously treated with cisplatin, other chemotherapeutic agents are not likely to be effective in relieving symptoms. METHODS: A pilot group of ten patients was treated with intraperitoneal alpha-2B-interferon (alpha-2B-IFN) in an effort to provide symptomatic relief of their ascites. All patients had advanced epithelial ovarian cancer at the time of therapy and were receiving treatment for palliation only. Symptoms included abdominal distention (100% of patients), nausea and vomiting in the absence of mechanical intestinal obstruction (60%), and dyspepsia (40%). RESULTS: At a dose of 10 M units/m2 given intraperitoneally every 2 weeks for one to four treatments, the toxicity was low, but the benefits were minimal. Five (50%) patients reported symptomatic improvement of 2-7 weeks' duration. The most common side effects included fever (temperature of more than 38.5 degrees C) and abdominal pain. CONCLUSIONS: At the dose of 10 M units/m2 of intraperitoneal alpha-2B-IFN, this regimen did not appear to produce clinically significant palliation of the ascites in most patients.

The charts and pathology specimens of 27 patients with ovarian tumors of low malignant potential were reviewed in an attempt to document the rationale for a second laparotomy in those patients with clinical stage 1 disease and who did not have a complete staging laparotomy at their initial surgery. Four of 13 patients with serous tumors, none of 12 patients with mucinous tumors, and one patient with a mixed tumor of LMP were upstaged at the staging laparotomy. The major morbidity rate associated with the procedure was 7.4%. The low yield of a staging laparotomy in patients with mucinous tumors (0%) does not warrant a second operation. The higher yield of a staging laparotomy in patients with serious tumors (30.8%) suggests that the likelihood of upstaging the disease exceeds the potential morbidity, and for this reason, the procedure may be warranted. However, the specific role of a staging laparotomy even in those with serous tumors awaits further study of the prognostic significance of invasive versus noninvasive implants.

Fifty-five ovarian mucinous tumours, 22 benign, 16 borderline and 17 malignant, were examined for intestinal differentiation (ID). This was defined by the presence of one or more of endocrine, absorptive, goblet or Paneth cells, and identified by routine haematoxylin and eosin as well as histochemical and immunoperoxidase techniques. Twenty benign (91%), 14 borderline (88%) and all malignant tumours contained foci of ID. The frequency of ID was not significantly different between the mucinous tumour types (chi-squared test for independence). Follow-up was available on all patients with borderline tumours: 14 were stage Ia, including both cases without ID, and 2 were stage Ic at presentation. All are alive and free of disease at 9-39 months (median 15.5 months). We conclude that the presence of ID in borderline mucinous tumours is unlikely to be of prognostic significance, and that a subdivision of these tumours into müllerian and intestinal types is unnecessary.
