Oral tropisetron, a 5-hydroxytryptamine type 3 (serotonin3) [5-HT3]-receptor antagonist, at a dose of 5mg daily was evaluated as antiemetic prophylaxis during postoperative abdominal irradiation. 20 women with International Federation of Gynecology and Obstetrics (FIGO) stage I to III ovarian carcinoma were included. 12 women received irradiation of whole abdominal fields and 8 of lower abdominal/pelvic fields. Efficacy and adverse events were recorded by the patients in diary-form booklets. The cumulative weekly incidence of patients with nausea, which was generally mild and of short duration, increased from 30% at the start of radiotherapy to 54% at the end of treatment. Episodes of vomiting occurred in less than 10% of the patients. Diarrhoea was common towards the end of the radiotherapy courses, and the proportion of patients needing extra antidiarrhoeal medication (loperamide) increased from 38% during the first week to 100% at the end of the radiotherapy course. Mean weight loss was 1.2kg during the 5- to 6-week course. Overall ratings for quality of life were excellent or good in 75 to 85% of patients. Tropisetron seems to be a promising and well tolerated drug in conjunction with extended radiotherapy of abdominal fields. This was an open study, establishing the methodology for long term follow-up of patients during fractionated radiotherapy.

Twenty patients with epithelial ovarian carcinoma were treated with high-dose cisplatin 200mg m-2. Patients were to receive three cycles at 21 day intervals. Treatment was stopped if severe myelosuppression or any neurotoxicity occurred. Overall, eight (40%) of patients responded with a complete response in five (25%). Four of 16 (25%) previously treated patients responded. The median duration of response was 44 weeks (range 6-130). In patients previously treated there was a significant association (P < 0.002) between response and a remission free interval of 52 weeks or more from primary chemotherapy. Toxicity was assessable in 18 patients. Alopecia and nausea/vomiting were common. Myelosuppression was recorded in nine patients delaying planned administration in eight of 35 cycles. Five patients developed anaemia and six thrombocytopenia. Neurotoxicity affected seven patients and varying degrees of tinnitus six patients. Neurotoxicity and myelosuppression were indications for cessation of treatment in 8 patients receiving less than three cycles. Analysis revealed no significant association between toxicity and prior cisplatin exposure, age or the amount of high-dose cisplatin administered. This series reveals that it is possible to achieve good response rates using high-dose cisplatin without encountering debilitating neurotoxicity.

Tropisetron, a 5-HT3 receptor antagonist, was evaluated as antiemetic prophylaxis during postoperative abdominal irradiation of ovarian carcinoma patients. Twenty consecutive women with Stages I-III (FIGO) epithelial ovarian carcinomas were included. At the start of radiotherapy all patients were clinically tumor-free. Twelve women received irradiation on whole-abdominal fields, 1.0 Gy per fraction, during 6 weeks. Eight women were irradiated on the lower abdomino-pelvic fields, 1.7 Gy per fraction, during 5 weeks. Efficacy and adverse events were recorded by the patients in diary-form booklets using visual analog scales (VAS). All patients completed the treatment series and none was lost to follow-up. Nausea, generally mild (mean 20 mm VAS) and of short duration, increased from start (30%) to end of radiotherapy (54%). Episodes of vomiting were few in number and occurred in less than 10% of the cases. Diarrhoea was common towards the end of the radiotherapy courses, especially when the dose per fraction was 1.7 Gy and the need for extra antidiarrhoeal medication (loperamide) increased from 38% at the start to 100% at the end. The mean weight loss was only 1.2 kg during 5-6 weeks. The overall ratings for quality of life were excellent or good in 75-85% of the cases. The efficacy of tropisetron was rated excellent or good in 80% of the cases and the tolerability likewise in 85% in the overall evaluation of the drug made by the investigator. Tropisetron therefore seems to be a promising and well-tolerated drug in conjunction with extended radiotherapy on the whole- or lower-abdominal fields.(ABSTRACT TRUNCATED AT 250 WORDS)

Spiroplatin was investigated in a multicenter phase II study, during which the drug was given over 4 h. 64 Patients with nine different solid tumors received 141 cycles of spiroplatin at a dose of 30 mg/m2 every 3 weeks. Most important side effects included nausea, vomiting, myelosuppression, and renal toxicity. Four of 11 evaluable patients with prior cisplatin developed increases in serum creatinine (3 transient, 1 died of renal failure). Of 51 patients without prior cisplatin 2 had a transient increase in serum creatinine levels, and 2 showed persistent changes, in 1 of them leading to hemodialysis. Pre- and posthydration did not reduce drug-induced nephrotoxicity. Only 3 patients showed a response; 1 with renal cell carcinoma, 1 with ovarian carcinoma, and 1 with malignant melanoma. Based on the absence of striking antitumor activity and on the presence of severe unpredictable renal toxicity, the study was stopped prematurely.

Refractory epithelial ovarian cancer is generally confined to the peritoneal cavity and is thus amenable to intraperitoneal (ip) therapy. Radiolabeled monoclonal antibodies raised to tumor-associated antigens offer the promise of selective tumor irradiation while reducing toxicity to normal tissues. We have conducted a phase I therapeutic trial to examine the feasibility of ip radioimmunotherapy utilizing escalating doses of 131I-labeled OC125 F(ab')2. Twenty-nine patients were each treated with a single dose of radiolabeled antibody. Twenty-eight patients were evaluable for dose-related toxicity. The toxicities most frequently observed were hematologic and gastrointestinal. Hematologic toxicity was noted in 5/14 (36%) patients receiving 18-87 mCi and in 12/14 (71%) receiving 100-144 mCi (P = 0.018). The median white blood cell nadir of 2-3K/microliters (range, 1.4-3.5K/microliters occurred at a median of 4.5 weeks and the median platelet nadir of 41K/microliters (range, 20-78K/microliters) at a median of 6.5 weeks. Mild gastrointestinal toxicity was observed in 4/14 patients (28%) at doses less than 100 mCi whereas at doses greater than or equal to 100 mCi, 11/14 (79%) patients developed nausea, vomiting, or chronic ileus (P = 0.021). This toxicity occurred most frequently in patients with protracted urinary 131I excretion. We conclude that 131I-labeled OC125 can be safely administered ip. Hematologic and gastrointestinal toxicity is predictable and related to the dose and rate of clearance of isotope.

A total of 16 patients with recurrent epithelial ovarian cancer were treated with sulofenur (LY 186641), a novel oral sulfonylurea. All subjects had received previous chemotherapy. Anaemia occurred in all 16 patients, 14 of whom required a blood transfusion, and 2/16 patients received methylene blue for breathlessness due to methaemaglobinaemia. Treatment was discontinued in 2/16 cases due to rising liver enzyme values, which reverted to normal on cessation of the drug. There was no nausea or alopecia. Only two minor responses were seen. Plasma drug levels were insufficient to result in antitumour activity as extrapolated from animal data. Further studies that attempt to increase the bioavailability and improve the therapeutic index are warranted.

A total of 248 analyzable patients with Stages III-IV ovarian epithelial cancer (114 with and 134 without prior chemotherapy) were randomized to one of four cisplatin (DDP)-hexamethylmelamine (HMM) regimens. In each, HMM, 200 mg/m2 was given orally daily on days 8-21 of each 21-day cycle. DDP was given i.v. on Day 1 at a dose of 37.5 mg/m2 (regimens A and B) or 75 mg/m2 (regimens C and D). In addition, since pyridoxine administration has been reported to reduce the neurotoxicity of HMM, that agent was given at a dose of 300 mg/m2 orally on Days 1-21 in regimens B and D. Randomization was stratified for performance status (0-1, 2-3) and largest tumor diameter at entry (greater than 2- less than or equal to 10 cm, greater than 10 cm) for previously untreated patients, and for performance status and time from initial diagnosis to entry on study (less than or equal to 1 year, greater than 1 year) for previously treated patients. The overall response rate (PR + CR) was 54%, with 25% of patients achieving a complete response. The 61% response rate with the higher dose DDP regimens was significantly greater than the 47% response rate with the lower dose regimens (p = 0.031). Multivariate analysis identified higher DDP dose, age less than 60 years, no prior chemotherapy, small tumor bulk and favorable tumor grade as significant prognosticators for response. The overall median response duration was 8.3 months (range 1-70 months). Prior chemotherapy, pyridoxine administration, recent diagnosis, and large tumor size were identified by multivariate analysis as factors adversely affecting response duration. Patients treated with the higher dose DDP regimens had more severe nausea, vomiting, and neurotoxicity. This study demonstrates that the combination of DDP + HMM is an effective regimen for advanced ovarian carcinoma that yields response rates comparable to other more complex regimens, and that there is a dose-response relationship for DDP in ovarian cancer. Although pyridoxine administration significantly reduced neurotoxicity, its adverse effect on response duration suggests that the agent should not be administered with DDP or HMM. The mechanism by which pyridoxine may unfavorably affect response duration deserves further investigation.

Ondansetron is a selective 5-HT3 antagonist with significant antiemetic properties in patients receiving cytotoxic chemotherapy. Patients who had suffered severe vomiting on carboplatin alone (23 patients with ovarian carcinoma) or in combination (two patients with testicular cancer) despite intensive antiemetic regimens were treated with ondansetron, given as 8 mg immediately prior to carboplatin followed by 8 mg orally, 8 hourly for 5 days. Twenty-five patients received 58 courses of ondansetron. In the first 24 h after the first course of chemotherapy with ondansetron, 17 patients (68%) experienced no vomiting, five patients (20%) had almost complete control and the other three patients had partial control. During the subsequent 4 days slightly lesser control was achieved. Nausea was similarly controlled in most patients. Twenty-two patients stated a preference for ondansetron with future chemotherapy. Fourteen patients received additional chemotherapy with ondansetron and in only three patients did the efficacy of therapy lessen. Toxicity was mild and transient with headache and constipation predominant. No extrapyramidal reaction was seen. Sedation was absent. Ondansetron is highly effective in refractory vomiting associated with carboplatin chemotherapy. It may be particularly beneficial when an extrapyramidal reaction has occurred on previous antiemetics and when sedation is unacceptable.

Twenty-one evaluable patients with FIGO stages II-IV epithelial ovarian cancer, median age 57 (range 47-75 years), were treated with ifosfamide (IF), 3 g/m2 diluted in 500 ml saline solution, 8 hour intravenous (i.v.) infusion on days 1-5; mesna 20% of IF dose, i.v. bolus injection, was given at hours 0 and 4; mesna 40% of IF dose by oral route at hours 8 and 12, days 1-5; plus cisplatin 20 mg/m2 diluted in 500 ml saline solution, 2 hour i.v. infusion, days 1-5. Cycles were repeated every 4 weeks. All patients had metastatic lesions (mesentery, pleura, colon, cervix, abdominal wall, lung, liver, bladder, and nodes). Toxicity ranged from mild to moderate. All patients experienced alopecia, nausea, and vomiting. Neutropenia and anemia ranged from mild to moderate. One patient experienced mild brain confusion and two patients microscopic hematuria. Ten clinically complete responses (47%) and five clinically partial responses (23%) were registered, for an overall 70% objective response. However, after a second look performance in 10 patients with clinically complete response, six of 10 patients showed a pathological complete response and four showed pathological partial response. The median duration of complete response is about 33 months, and median partial response duration is 14 months. Although the numbers are small, these data indicate that combination chemotherapy with high dose ifosfamide/mesna plus cisplatin may be an active treatment for advanced ovarian carcinoma.
