This is the report of results from a phase 2 trial of high-dose progestin therapy for treatment of ovarian cancer. 19 women received 1000 mg of Depo Provera (medroxyprogesterone acetate) weekly by intramuscular injection for at least 8 weeks and longer if there was no evidence of tumor progression. None of the women in the study was responding any longer to surgery, radiation therapy, or conventional cytotoxic chemotherapy. Response was measured as: 1) regression if there was at least a 50% decrease in the area of measurable lesion; or 2) disease progression as at least a 25% increase over the original measurements or the appearance of new lesions. Based on these criteria, there were no responses in the 19 women. Only 1 patient remained stable (3 months). Median survival time was 2 months with 75% of the patients dying within 4 months. 1 patient suffered severe vomiting and another experienced bleeding; there was no other toxicity. It is concluded that progestin therapy does not have a beneficial effect and its use in ovarian cancer patients should be limited to those with endometrioid histology.

Topoisomerase I inhibitors are a new therapeutic class whose clinical evaluation began a few years ago; Irinotecan (CPT-11) gave interesting results in colon cancer; side effects were neutropenia, diarrhea, vomiting and a cholinergic syndrome. Topotecan was useful in lung and ovarian cancer; side effects were mostly hematologic. Undergoing studies concern dose optimization, mode of administration and therapeutic associations.

Bowel obstruction is a common and distressing outcome in patients with abdominal or pelvic cancer. Patients may develop bowel obstruction at any time in their clinical history, with a prevalence ranging from 5.5% to 42% in those with ovarian cancer and from 10% to 28.4% in those with colorectal cancer. The causes of the obstruction may be benign postoperative adhesions, a focal malignant or benign deposit, or relapse or diffuse carcinomatosis. The symptoms, which are almost always present, are intestinal colic, continuous abdominal pain, nausea, and vomiting. Although surgery should be the primary treatment for malignant obstruction, it is now recognized that some patients with advanced disease or in generally poor condition are unfit for surgery and require alternative management to relieve distressing symptoms. A number of treatment options are now available for the patient with advanced cancer who develops intestinal obstruction. In this review, the indications for surgery are examined, the use of nasogastric tube and percutaneous gastrostomy evaluated, and the pharmacologic approach described.

Docetaxel has been evaluated in 293 patients with advanced ovarian cancer in three phase II trials. All patients had previously received cisplatin and/or carboplatin as first-line treatment. In all three studies, treatment comprised docetaxel 100 mg/m2 as a 1 h intravenous infusion every 3 weeks, without premedication for hypersensitivity reactions or emesis. To date, 200 patients are evaluable for response. Of these, 63 patients achieved complete or partial response, giving an overall response rate of 31.5% (95% confidence interval 24-39%) for all evaluable patients, or 21.5% for all patients entered in the studies. Of the 57 patients whose disease had progressed either during previous therapy or within 4 months of discontinuing previous therapy, 13 (23%) responded to docetaxel (EORTC data). Major adverse effects of docetaxel observed in approximately half the patients (particularly those who received more than four courses) included skin reactions and fluid retention. Grade III or IV neutropenia was common but short-lived. Severe acute hypersensitivity reactions occurred in approximately 5% of patients. Docetaxel now warrants evaluation as part of first-line therapy. Studies aimed at reducing the incidence of fluid retention and skin reactions with docetaxel are ongoing.

The efficacy and toxicity of intraperitoneal (i.p.) cisplatin plus systemic etoposide were studied in 36 patients with small (< 2 cm) residual i.p. ovarian cancer after achieving a partial response to platinum-based, first-line chemotherapy. Treatment comprised 90 mg/m2 i.p. cisplatin with intravenous (i.v.) sodium thiosulphate (day 1) and 600-800 mg/m2 i.v. etoposide (days 1 and 2), every 4 weeks for four to six cycles. 7 patients achieved a pathological complete response (pCR), one a pathological partial response and 16 were clinically stable without evidence of disease. After a median follow-up of 13 months, the median progression-free survival (PFS) was 11 months (95% confidence interval 7-16 months). The actuarial PFS at 24 months is 22% (95% confidence interval 8-36%). Three of six relapses after achieving a pCR (50%) were sited i.p., and 9 of 14 other patients with disease progression (64%) had an i.p. relapse, indicating insufficient local efficacy. There was no renal toxicity, but grade 3-4 leucopenia occurred in 63% and grade 3-4 thrombocytopenia in 8% of cycles, while nausea, vomiting and complete alopecia were common. Although side-effects were acceptable, the efficacy of treatment with i.p. cisplatin plus i.v. etoposide is limited.

Primary adenocarcinoma of the jejunum which accounts for only approximately 3% of all gastrointestinal tract malignancies, is distinctly unusual. Ovarian metastasis from a jejunal cancer is extremely rare. It has significant therapeutic and prognostic implications to differentiate primary ovarian carcinoma from metastatic disease to the ovary. A 49-year-old Japanese woman presented with intermittent nausea, vomiting, and palpable abdominal mass. Pelvic examination and imaging studies revealed a huge ovarian tumor, suspicious for malignancy. Upper GI series and barium enema were unremarkable. Exploratory laparotomy was done for presumed primary ovarian malignancy. Mucinous adenocarcinoma of the right ovary, measuring 25 x 18 x 12 cm, without other intraabdominal dissemination was found. Exploration of the upper abdomen revealed an annular constriction of the jejunum 30 cm distal to the ligament of Treitz. Partial jejunectomy with end-to-end anastomosis was done. Metastatic ovarian cancer from the primary jejunal adenocarcinoma was confirmed microscopically. Although small bowel malignancy is uncommon, small bowel follow-through examination or enteroclysis may be indicated in patients with positive stool for occult blood who have no abnormality in the upper gastrointestinal series and barium enema. In addition to the imaging studies, thorough exploration of the entire abdominal cavity is necessary at ceiliotomy in patients with ovarian malignancy to distinguish primary ovarian cancer from metastatic disease to the ovary.

The QLQ-C30, a health-related quality of life questionnaire developed for use in patients with cancer, has been previously validated in patients with lung cancer and head and neck cancer. In this study, further validation was carried out for 535 patients, including patients with breast cancer (n = 143) and ovarian cancer (n = 111) for whom there is no previously published validation, as well as patients with lung cancer (n = 160) and a heterogeneous group of other cancers (n = 121). All patients were entered in one of two trials of anti-emetics to prevent chemotherapy-induced emesis. The QLQ-C30 was completed before chemotherapy and on day 8 after chemotherapy. The factor structure in patients with breast and ovarian cancer was similar to that previously described. Interdomain correlations, in the entire group, were strongest for the physical and role function domains and the fatigue, pain and global quality of life domains before and after chemotherapy. In addition, after chemotherapy, social function was also strongly correlated with fatigue and global quality of life. These correlations were not always of equal strength in the breast, ovarian and lung groups, suggesting that there may be differences between these groups. The responsiveness of the QLQ-C30 in the presence of widely metastatic, as compared with locoregional, disease showed changes in the expected directions (i.e., diminished function in physical and social role functions and in global quality of life, with greater fatigue and pain in patients with metastatic disease). Eight days after chemotherapy, decreases were seen in physical, role and social functioning and in global quality of life, and there was greater fatigue, nausea and vomiting compared with before chemotherapy. Patients with breast cancer had better physical, role and social functioning and less fatigue and pain than patients with ovarian cancer. This result is expected, since many of the patients with breast cancer had early stage disease, whereas those with ovarian cancer had advanced stage disease. Mean scores for patients with lung cancer were between the other two groups, in keeping with the mixture of early and advanced stage disease in these patients. There was a strong correlation between ECOG performance status scores and several domains of the QLQ-C30; these were all in the expected directions. The results of this study confirm those in earlier studies on patients with lung cancer, and provide new information on patients with breast and ovarian cancer. In addition, the QLQ-C30 is responsive to the effects of chemotherapy and of metastatic disease.

Paclitaxel is a novel antineoplastic that effects cytotoxicity by promoting intracellular tubulin polymerization and stabilizes abnormal microtubule structures against depolymerization. Although its clinical development had been hampered by misconceptions about its pharmacology, its scarcity, difficulties extracting it from its natural source, formulation problems, and frequent severe hypersensitivity reactions, paclitaxel recently was approved for treatment-refractory ovarian cancer. Two major adverse effects are dosage- and schedule-related myelosuppression and mucositis. Neurotoxicity is directly related to both the individual and cumulative doses. Other relevant toxicities are hypersensitivity reactions, effects on cardiac rate and rhythm, arthralgias and myalgias, generalized hair loss, and mild nausea and emesis. Continuing clinical studies will evaluate paclitaxel as initial therapy for ovarian cancer and its utility in other malignancies. In addition, major efforts are under way to develop alternative sources to increase the availability of taxene analogs and reduce our dependence on yew species.

The relation between pretreatment night-time urinary catecholamine excretion and chemotherapy-induced nausea and vomiting was studied. The first cohort included 17 women and three men with various cancer forms receiving low or moderately emetogenic chemotherapy. The second cohort included 42 women receiving cisplatinum (50 mg m-2) for ovarian cancer and ondansetron as an antiemetic (8 mg i.v. x 3 at chemotherapy and 8 mg p.o. x 3 for 5 days). Relatively higher noradrenaline, but not adrenaline, excretion was associated with an increased intensity of delayed nausea following treatment. Vomiting was not consistently related to the excretion of either catecholamine. The results indicate that noradrenaline modulates delayed nausea resulting from chemotherapy.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given as a 24-hour infusion, and carboplatin have activity in advanced non-small cell lung cancer (NSCLC) and ovarian cancer. Two dose-finding studies were initiated to identify the optimal doses for the paclitaxel/carboplatin combination when paclitaxel is given in a 3-hour infusion. The fact that the pharmacologic interaction between paclitaxel and cisplatin increases the toxicity of paclitaxel when cisplatin is given before it also prompted an investigation of the influence of drug sequence on toxicity and pharmacokinetics in the NSCLC trial. Thirty-three patients with advanced NSCLC and 11 with advanced ovarian cancer previously untreated by chemotherapy have been enrolled to date. In the NSCLC trial escalating doses of paclitaxel were given in combination with a fixed carboplatin dose of 300 mg/m2, while both drugs were escalated in the ovarian cancer study. In both studies paclitaxel was infused over 3 hours and carboplatin over 30 minutes, and cycles were repeated every 4 weeks. The most frequent side effect has been neutropenia, although this did not result in any infectious episodes. Alopecia and mild emesis also have been frequently encountered. Mild skin reactions have been reported in a few patients. Bone pain and myalgia occur more frequently at the highest paclitaxel doses. No difference in toxicity has been observed thus far between the two drug sequences in the NSCLC study. Both studies are still accruing patients as the maximum tolerated doses of paclitaxel in combination with carboplatin have not yet been reached (carboplatin 300 mg/m2 with paclitaxel 175 mg/m2 in the NSCLC study; carboplatin 400 mg/m2 with paclitaxel 150 mg/m2 in the ovarian cancer study). An investigation of maximum tolerated doses with granulocyte colony-stimulating factor support is planned thereafter.
