5077 Background: The standard chemotherapy for epithelial ovarian cancer (EOC) is carboplatin and paclitaxel every 3 weeks together with debulking surgery. This phase II trial was designed to determine the safety and efficacy of weekly carboplatin and paclitaxel treatment in patients with EOC. Methods: Between October 2003 to August 2005, 37 patients with stage Ic-IV epithelial ovarian, tubal or primary peritoneal carcinoma were enrolled into the study. Carboplatin at AUC=2 and paclitaxel at 80 mg/m 2 were administered on days 1,8,15 of a 28-day cycle. Cytoreductive surgery was performed as primary treatment or after 3 cycles of neoadjuvant chemotherapy with additional chemotherapy after the surgery. Results: Median age of the patients was 67 (range 49–82). A mean of 6 chemotherapy cycles were administered (range 3–8). Median time of follow-up (from the beginning of chemotherapy until the last follow-up visit) was 15.57 months (range 0.2–26months). Thirty-three patients were evaluable for response. Complete response (CR) was observed in 26 patients (78.8%) and partial response (PR) in 7 (21.8%). By the time of data collection 13 out of 33 women (39.4%) experienced recurrent or persistent disease and one patient (3%) died from progressive disease during 2 nd line chemotherapy. Since 20 out of 33 patients are still free of disease and all but one are still alive, it is too early to evaluate time to progression (TTP) and overall survival (OS). The median time to disease recurrence or progression after completion of primary chemotherapy was 7.5+ months (0.2–18.2+). As for toxicity; grade 3 and 4 neutropenia were seen in 5 (13.5%) and one patient (2.7%) respectively. There was no neutropenic fever. Other grade 3 and 4 hematologic toxicities were not observed. Six (16.2%) and 5 (13.5%) patients needed G-CSF and Epoetin support respectively. The main non-hematologic toxicities were alopecia (grade 1) and fatigue (grade 3 in two patients). Only two patients (5.4%) experienced grade 3 neuropathy. Conclusion: Weekly treatment with carboplatin and paclitaxel is feasible and well tolerated. The low toxicity rate especially regarding neuropathy warrants further investigation of this regimen. No significant financial relationships to disclose.
1040 Background: The randomized phase III TURANDOT trial compared first-line BEV plus paclitaxel (PAC) vs BEV plus capecitabine (CAP) in HER2-negative metastatic BC (mBC). BEV-based regimens are often favored in TNBC [Dawood 2012] because of efficacy in subgroup analyses and a lack of effective treatments. We performed an exploratory subgroup analysis of TURANDOT to provide more data on BEV-based therapy in TNBC. Methods: Patients (pts) with HER2-negative mBC who had received no prior chemotherapy for mBC were randomized to either BEV–PAC (BEV 10 mg/kg d1 and 15 + PAC 90 mg/m 2 d1, 8, and 15 q4w) or BEV–CAP (BEV 15 mg/kg d1 + CAP 1000 mg/m 2 bid d1–14 q3w). The primary endpoint was overall survival (OS); secondary endpoints included objective response rate (ORR), progression-free survival (PFS), and safety. Results: Of 561 pts treated, 130 had TNBC. Baseline characteristics were typical of a poor-prognosis population and generally balanced between treatment arms, although fewer pts receiving BEV–PAC than BEV–CAP had ECOG PS 1/2 (25% vs 40%, respectively), positive lymph nodes (56% vs 72%), metastatic disease at first diagnosis (19% vs 30%), and liver metastases (27% vs 43%). Median age was 54 vs 56 years, respectively. At data cut-off, median follow-up was 21.4 vs 19.2 mo for BEV–PAC and BEV–CAP, respectively. The safety profiles in the TNBC subgroup were similar to the overall population. The predominant grade ≥3 AEs were hematologic AEs and neuropathy with BEV–PAC and hand-foot syndrome and diarrhea with BEV–CAP. Conclusions: One-year OS rates up to 78% in TURANDOT are among the highest seen in TNBC. BEV-based therapy is a valid option in a setting with limited active treatments. BEV–PAC may be favored based on 1-year OS, PFS, and ORR. Clinical trial information: NCT00600340. [Table: see text]
A case is presented of endometrioid carcinoma of the ovary, metastasizing to the breast in a 63‐year old woman. Differentiation of metastatic cancer to the breast for primary breast carcinoma and discovering the primary tumor site are rather important for treatment and prognosis. Lumpectomy, followed by panhysterectomy, was performed and six courses of cisplatinum and cyclophosphamide were given. No signs of recurrence or metastasis are apparent 16 months after the discovery of the breast lesion.
Seven patients with progressive localized or metastatic chemo-resistant osteosarcoma were treated by gemcitabine.The protocol included gemcitabine 1000 mg/m2/w for 7 consecutive weeks, followed by 1 week rest. If no progression was observed,maintenance by gemcitabine 1000 mg/m2/w for 3 weeks every 28 days was given until failure was clinically or radiologically evident.Results. The true objective response rate was 0%. However, disease stabilization and clinical benefit response were observed in five patients (70%) for 13-96 weeks.Discussion. Postponing the inevitable death with a relatively non-toxic treatment, is, in our opinion, an important issue especially in young patients.Thus it may be justified and warranted to investigate the activity of gemcitabine in a larger group of patients with bone sarcomas.
5122 Background: Five years survival of patients with advanced epithelial ovarian cancer (EOC) is 25–40% and once the disease recurs, treatment is mainly palliative. We evaluated whether continued treatment with carboplatin for an extended one-year period in women with complete response after platinum based combination, could prolong time to progression (TTP) and overall survival (OS). Methods: 14 patients were assigned to the protocol between 2/1996 to 6/2002 at the Oncology Division in Tel Aviv Sourasky Medical Center. Protocol schedule was: administration of Carbopltin at an AUC=6, three treatments every 2 months followed by two treatments once every three months (for a total of one year). All patients were previously treated with platinum based combinations and had achieved complete response (CR) by CT-scan and serum CA-125. Results: As of December 2003 with a median follow up of 42 months (range 18–93 months), the median TTP is 28 months (range 8–93+ months), and a median OS of 42 months (range 18–93+ months). Eight patients are still in complete remission and two more patients are still alive with disease. Conclusions: One year treatment (5 cycles) of single agent carboplatin that was administered to women with advanced EOC who achieved CR on platinum based chemotherapy as a first line, significantly prolonged TTP and OS compared to historical control.
