Purpose: To evaluate the impact of two different intraperitoneal (IP) chemotherapy regimens on progression-free survival (PFS) among women with newly diagnosed advanced ovarian carcinoma., Methods: Eligible patients were randomly assigned to six cycles of IV paclitaxel 80 mg/m 2 once per week with intravenous (IV) carboplatin area under the curve 6 (IV carboplatin) versus IV paclitaxel 80 mg/m 2 once per week with IP carboplatin area under the curve 6 (IP carboplatin) versus once every 3 weeks IV paclitaxel 135 mg/m 2 over 3 hours day 1, IP cisplatin 75 mg/m 2 day 2, and IP paclitaxel 60 mg/m 2 day 8 (IP cisplatin). All participants received bevacizumab 15 mg/kg IV every 3 weeks in cycles 2 to 22., Results: A total of 1,560 participants were enrolled and had 84.8 months of follow-up. The median PFS duration was 24.9 months in the IV carboplatin arm, 27.4 months in the IP carboplatin arm, and 26.2 months in the IP cisplatin arm. For the subgroup of 1,380 patients with stage II/III and residual disease of 1 cm or less, median PFS was 26.9 (IV-carboplatin), 28.7 (IP-carboplatin), and 27.8 months (IP cisplatin), respectively. Median PFS for patients with stage II/III and no residual disease was 35.9, 38.8, and 35.5 months, respectively. Median overall survival for all enrolled was 75.5, 78.9, and 72.9 months, respectively, and median overall survival for stage II/III with no gross residual disease was 98.8 months, 104.8 months, and not reached. Mean patient-reported Functional Assessment of Cancer Therapy neurotoxicity scores (Gynecologic Oncology Group) were similar for all arms, but the mean Trial Outcome Index of the Functional Assessment of Cancer Therapy-Ovary scores during chemotherapy were statistically worse in the IP cisplatin arm., Conclusion: Compared with the IV carboplatin reference arm, the duration of PFS was not significantly increased with either IP regimen when combined with bevacizumab and was better tolerated than IP cisplatin.

Purpose: To assess progression-free survival (PFS) and overall survival (OS) in patients with suboptimally debulked epithelial ovarian cancer receiving cisplatin (100 mg/m(2)) or 24-hour infusion paclitaxel (200 mg/m(2)) or the combination of paclitaxel (135 mg/m(2)) followed by cisplatin (75 mg/m(2))., Patients and Methods: After stratification for disease measurability, patients were randomized to receive six cycles of one of the treatments every 3 weeks. If measurable, complete response (CR) or partial response (PR) was determined., Results: Six hundred fourteen of 648 patients who entered onto the trial were eligible. Monotherapies were discontinued more frequently (cisplatin because of toxicity or patient refusal [17%], and paclitaxel because of progression [20%]) compared with the combination therapy (7% and 6%, respectively). Neutropenia, fever, and alopecia were more severe with paclitaxel-containing regimens; whereas anemia, thrombocytopenia, neurotoxicity, nephrotoxicity, and gastrointestinal toxicity were more severe with cisplatin-containing regimens. The CR/PR rates on paclitaxel monotherapy were significantly lower compared with the cisplatin regimens (42% v 67%, respectively; P <.001). The relative hazard (RH) of first progression or death was significantly greater among those randomized to paclitaxel (RH = 1.41; 95% confidence interval [CI], 1.15 to 1.73; P <.001) when compared with cisplatin; however, RH did not differ significantly between the two cisplatin regimens (RH = 1.06; 95% CI, 0.895 to 1.30). Relative to cisplatin, the death rate on paclitaxel was 15% greater (RH = 1.15; 95% CI, 0. 929 to 1.42), and the death rate on the combination treatment was 1% less (RH = 0.99; 95% CI, 0.795 to 1.23). These differences among treatment groups were not statistically significant (P =.31)., Conclusion: Cisplatin alone or in combination yielded superior response rates and PFS relative to paclitaxel. However, OS was similar in all three arms, and the combination therapy had a better toxicity profile. Therefore, the combination of cisplatin and paclitaxel remains the preferred initial treatment option.

Purpose: From December 1983 through February 1992, a prospective study designed to determine the clinical course of patients with ovarian tumors of low malignant potential (LMP) was conducted by the Gynecologic Oncology Group (GOG)., Materials and Methods: This protocol was developed to evaluate the following (1) the biologic behavior of ovarian LMP tumors, (2) the effectiveness of melphalan chemotherapy in patients with clinically detectable residual disease after surgical staging and in patients whose tumors progress or recur after surgical therapy, and (3) the response rate to cisplatin in those who failed to respond to melphalan therapy. The study group consisted of 146 assessable patients with stage I serous LMP tumors. All of these women had the affected ovary (or ovaries) removed, and a complete staging operation was performed in each case. While 123 patients had a total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO), 21 retained the uterus and one normal-appearing ovary and fallopian tube. No adjuvant chemotherapy or radiation therapy was administered to any patients in the stage I study group., Results: The median follow-up time was 42.4 months (range, 1.6 to 108). Thus far, no patient with a stage I ovarian serous LMP tumor has developed recurrent disease., Conclusion: Stage I ovarian serous LMP tumors rarely, if ever, recur. Limited resection, after meticulous surgical exploration, is adequate therapy for women of reproductive age.
