Six patients with recurrent ovarian cancer who had prior chemotherapy were studied for the clinical efficacy of CDDP-ACR treatment. Five out of the 6 had received CDDP a total doses of 1,320, 780, 750, 475, and 340 mg. CDDP-ACR therapy consisted of continuous infusion of CDDP at a daily dose of 10 mg/m2 over 14 days (total CDDP doses; 140 mg/m2) and of intermittent infusion of ACR (aclarubicin) at a dose of 20 mg/body every other day (total ACR doses: 140 mg). There were one CR and five PR and a response rate up to 100% was noted. Toxicity was manifested in slight nausea or vomiting, but there was no nephrotoxicity. However bone marrow was severe. Thrombocytopenia less than 50,000/mcl in 4 pts (67%) and leukopenia less than 1,000 mcl in 3 pts (50%). The mean filterable platinum exposure measured by area under the concentration-time curve (AUC) was as high as 19.7 +/- 6/0 mg.hr/ml. In conclusion the bone marrow toxicity in this regimen was severe, but the therapeutic efficacy was promising. Further studies on the appropriate infusion time and the minimum effective dose of CDDP are needed.

We administrated cis-platinum 70-100 mg/m2 bolus, intraperitoneally or intrapleurally without diluting in saline, simultaneously combined with intravenous injection of sodium thiosulphate 1 gr/hr for 12 hours continuously or additional loading of sodium thiosulphate 4-6 g bolus on the initiation. The procedure does not require transfusion of specific hydration and keeps urine volume at a certain level, much less diuretics. For the treatment of 6 gynecological malignancies (2 primary ovarian carcinoma, 1 recurrent ovarian carcinoma, 1 pseudomyxoma peritonei, 1 clear cell carcinoma of cul de sac and 1 metastatic pleuritis carcinomatosa due to uterine cervical carcinoma) 12 courses treatments have been performed, without inducing nephrotoxicity except mild vomiting. All six cases are evaluable for efficacy according to Saito-Koyama criteria at this time: 4 CRs including 2 CRs for ascites and pleural effusion, 1 NC and 1 PD. This Two-Channel Chemotherapy (TCC) seems to be an important modality of chemotherapy for ovarian carcinoma in future.

JM216 [bis-acetato-ammine-dichloro-cyclo-hexylamine-platinum (IV)] is an oral platinum complex with in vivo activity against murine and human tumor models and a lack of nephro- and neurotoxicity in rodents. During a phase I study of a single-dose schedule, JM216 was given in dry-filled hard gelatin capsules by mouth without hydration or diuresis. In all, 37 patients were given a total of 88 courses at doses ranging from 60 to 700 mg/m2. The study was stopped before the MTD was reached because of nonlinear pharmacokinetics. Myelosuppression was manifest by leucopenia or thrombocytopenia and showed marked variability at 420-700 mg/m2. Vomiting was mild and controllable by antiemetics in approximately 50% of courses. The onset of vomiting was delayed to 4 h after during ingestion. There was no nephro-, oto- or neuro-toxicity. A partial response was recorded in a patient with recurrent ovarian cancer, and significant falls in plasma tumour markers (CA125) were seen in two further cases. Plasma pharmacokinetics were linear and showed moderate interpatient variability at dose levels of < or = 120 mg/m2. At dose levels of > or = 200 mg/m2, Cmax and AUC increased less than proportionally to dose. This was associated with greater interpatient pharmacokinetic variability and reduced urinary platinum recovery. A significant sigmoidal relationship existed between ultrafilterable plasma AUC and the percentage of reduction in platelet count (r2 = 0.78). Nonlinear absorption was a limitation to this single-dose schedule of oral NM216; however, little non-haematological toxicity was seen at doses associated with myelosuppression and antitumour activity. Clinical studies of divided dose schedules using doses within the range of pharmacokinetic linearity (< or = 120 mg/m2) are now being investigated.

In a non-randomized clinical trial, combined intraperitoneal therapy with recombinant interferon alpha-2b (20-50 MU) and mitoxantrone (20-50 mg) was studied for recurrent ovarian cancer with ascites. Altogether 19 patients were treated. After primary operation, all patients had received intravenous chemotherapy, 16 of which included cisplatin. One patient had complete response, seven patients partial response, four no change and seven progressive disease. The mean duration of the responses was 5+ months (range 1-12), and mean survival time 4.5+ months (range 1-14+). Eight patients had side effects (flu-like symptoms, dyspnea, abdominal pain, vomiting, diarrhea, fever and bowel obstruction). It was concluded that the formation of ascites in refractory ovarian cancer can be reduced with intraperitoneal administration of interferon alpha-2b and mitoxantrone, with tolerable side effects.

Forty-two patients affected by either stage III and IV ovarian cancer with residual tumor after surgery or recurrent ovarian cancer entered a phase II study of the combination carboplatin 300 mg/m2 and cyclophosphamide 600 mg/m2 every 28 days. Thirty-eight patients were evaluable for response and of these 27 obtained complete or partial remission with a 71% overall remission (clinical complete remission 45%; partial remission 26%). Treatment tolerability was on the whole good. The most frequent side effects were leukopenia (76%), anemia (67%) and nausea/vomiting (60%). Thrombocytopenia was present in 31% of the patients, but nearly always to a mild degree except for one grade 4 case. No other grade 4 side effect was observed. We did not observe any cases of nephrotoxicity and only two patients complained of paresthesia. This carboplatin-cyclophosphamide combination in advanced ovarian carcinoma produces comparable results, in terms of objective responses, to those obtained with standard cisplatin-based regimens, with suggestion of a better toxicological profile.

We retrospectively reviewed the medical records of 21 patients with advanced epithelial ovarian carcinoma treated with intravenous chemotherapy in an attempt to restore intestinal function following small-bowel obstruction. All patients had a drainage gastrostomy tube placed for palliation of vomiting, and 11 patients received concomitant total parenteral nutrition (TPN). Eight (38%) patients were treated with single-agent paclitaxel, 7 (33%) received platinum-based regimens, and 6 (29%) received other second-line chemotherapy. The median survival for all patients post-gastrostomy tube placement was 84 days. The median survival for patients with recurrent ovarian cancer who received salvage chemotherapy and TPN was 89 days, longer than for patients who received salvage chemotherapy alone (71 days) (P = 0.031). Two of three patients with newly diagnosed ovarian cancer and concomitant bowel obstruction had sufficient temporary response from chemotherapy with resolution of obstruction and removal of the gastrostomy tube. Chemotherapy was ineffective in restoring bowel function in heavily pretreated patients with recurrent disease.

The topoisomerase I inhibitor topotecan has shown antitumour activity against a variety of tumour types in vitro and in vivo. Topotecan in combination with drugs that induce DNA damage generally results in synergistic killing of tumour cells in vitro. As the activity of topotecan is related to exposure time, the drug is administered by intravenous infusion either continuously or once daily over a 30-minute period for several consecutive days. A 30-minute infusion of topotecan 1.5 mg/m2 on 5 consecutive days every 3 weeks produced response rates of up to approximately 20% in patients with advanced ovarian cancer who had failed to respond to platinum-based regimens or relapsed after initial response to such regimens. No significant differences in efficacy were apparent between topotecan and paclitaxel in a phase III study in patients with recurrent ovarian cancer, although a trend in favour of topotecan was evident for all major efficacy parameters. Non-cumulative myelosuppression, including neutropenia, thrombocytopenia and anaemia, is the dose-limiting toxicity associated with topotecan. Myelo-suppression was significantly more common with topotecan than with paclitaxel in a single comparative study. Non-haematological adverse events in topotecan recipients are generally mild and include alopecia, nausea, vomiting, and other gastrointestinal problems. Thus, topotecan has modest efficacy in the treatment of recurrent advanced ovarian cancer, with clinical activity similar to that of paclitaxel in a large randomised phase III study in this setting. Combinations of paclitaxel and a platinum compound are being used increasingly for first-line therapy, although relapse rates remain significant. Topotecan is therefore a suitable second-line option, providing antitumour response for some patients whose disease has relapsed after, or is refractory to, platinum-based therapy. Its wider potential when used either alone or in combination regimens should become clearer from ongoing studies.

We evaluated the feasibility of high-dose CEP (cyclophosphamide 750 mg/m2, epirubicin 90 mg/m2, cis-platinum 70 mg/m2) therapy, with granulocyte colony-stimulating factor support every 21 days, in 18 patients with advanced and recurrent ovarian cancer. Ten patients (56%) received 6 cycles of this regimen as planned. Toxicities more than grade 3/4 on' the WHO scale of neutropenia and thrombocytopenia were observed in all cases. Nausea, vomiting, mucositis, malaise, alopecia, hepatotoxicity, and fever were common adverse effects. The average relative dose intensity of cyclophosphamide, epirubicin, cis-platinum was 0.77, 0.77, 0.79 respectively, and each RDI decreased in the last two cycles. These data suggest that this regimen could be performed safely with careful consideration on hepatotoxicity and thrombocytopenia.

Both weekly cisplatin chemotherapy and single agent topotecan have proven to be effective in recurrent ovarian cancer. Preclinical data show synergism between cisplatin and topotecan. Side effects for this combination are drug sequence dependent and predominantly haematologic. Since preclinical data suggest that Cremophor EL (CrEL), the formulation vehicle of paclitaxel, has a protective effect on haematological toxicity of cisplatin, CrEL was added to the combination cisplatin and topotecan. In this phase I study, escalating doses of oral topotecan administered on day 1, 2, 8, 9, 15, 16, 29, 30, 36, 37, 43, 44 were combined with weekly cisplatin 70 mg m(-2) d(-1) on day 1, 8, 15, 29, 36, 43 (scheme A) or with the presumably less myelotoxic sequence weekly cisplatin day 2, 9, 16, 30, 37, 44 (scheme B). In scheme C, CrEL 12 ml was administered prior to cisplatin in the sequence of Scheme A. 18 patients have received a total of 85 courses. In scheme A 4/10 patients, all treated with topotecan 0.45 mg m(-2) d(-1), experienced DLT: 1 patient had vomiting grade 4, 1 patient had grade 4 neutropenia >5 days, 1 patient had >2 weeks delay due to thrombocytopenia and 1 patient due to neutropenia. Both patients in scheme B (topotecan 0.45 mg m(-2) d(-1)) had DLT due to a delay > 2 weeks because of prolonged haematological toxicity. No DLT was observed in the first 3 patients in scheme C (topotecan 0.45 mg m(-2) d(-1)). However, 2 out of 3 patients treated at dose level topotecan 0.60 mg m(-2)d(-1) in scheme C experienced DLT due to >2 weeks delay because of persistent thrombocytopenia or neutropenia. We conclude that there is a modest clinical effect of CrEL on haematological toxicity for this cisplatin-based combination regimen, which seems to reduce these side effects but does not really enable an increase of the oral topotecan dose.

Gemcitabine and oxaliplatin have shown single-agent activity in relapsed ovarian cancer. This combination was used to determine response rates, time-to-event efficacy measures, and toxicity in patients with recurrent ovarian cancer. Patients with prior platinum-based chemotherapy who had measurable lesions and/or elevated CA-125 levels were identified as group A (platinum-refractory/platinum-resistant patients) and group B (platinum-sensitive patients). All patients received gemcitabine 1000 mg/m(2) on days 1 and 8 and oxaliplatin 130 mg/m(2) on day 8 every 21 days for up to eight cycles. Seventy-five patients (21 in group A and 54 in group B), with a median age of 58 years (range, 37-78), were enrolled. A median of six cycles (range, 1-8) was administered. By intent-to-treat analysis, 15 patients with measurable disease achieved partial response for an overall best response rate of 20.0% (9.5% in group A and 24.1% in group B). CA-125 response was observed in 48.4% patients (30.0% in group A and 57.1% in group B). Median time to progressive disease was 7.1 months (95% CI, 5.6-9.0 months) with 5.0 months in group A and 8.3 months in group B. Median overall survival was 17.8 months (95% CI, 12.9-21.3 months) with 9.2 months for group A and 20.0 months for group B. Major grade 3/4 toxicities were neutropenia (61.3%), leukopenia (24.0%), nausea (16.0%), and vomiting (22.7%). We conclude that the combination of oxaliplatin and gemcitabine is active in patients with recurrent ovarian cancer, but the regimen is unsatisfactory for further study due to modest response and relatively high toxicity.
