简要总结
Uterine sarcomas account for less than 5% of all carcinomas of the uterine corpus. The prognosis of these patients is extremely limited. Recurrence rates of 50-60% are reported even for early-stage disease (FIGO I/II). Median overall survival is below 12 months in patients with advanced or metastatic disease.
Ovarian carcinosarcoma is extremely rare among ovarian malignancies (< 2%). That is why there is insufficient data as a basis for establishing a gold standard. As a result, these cases tend to be treated in the same way as uterine sarcomas or epithelial ovarian malignancies in clinical practice.
On the basis of data published to date on the treatment of mixed mesenchymal-epithelial tumors, it is clear that the treatments commonly used to date have limited activity while producing clinically relevant toxicity. The regimes verified so far (Cisplatin / Ifosfamide, Ifosfamide/Paclitaxel and Gemcitabine/Docetaxel) exhibit a considerable side effect spectrum and are only rarely feasible on clinical everyday life conditions, so e. g. the rate of withdrawals due to toxicity was in a study collective of selected females treated with the last combination at 40 %. The physician has to check in every individual case if one of the above mentioned combinations is feasible. The search for alternative effective and better tolerated treatment options is essential. The toxicity data on the carboplatin-PLD combination are known, and efficacy has been identified in small cohorts.
The objective of this study is to explore the efficacy of combination PLD-carboplatin treatment in a larger patient population.
详细描述
This study in patients with mesenchymal or mixed epithelial mesenchymal tumors of the ovary or uterus is designed as a prospective single-arm, open - label, multicenter phase II study to evaluate the efficacy of PegLiposomal Doxorubicin and Carboplatin combination chemotherapy.
40 patients will be recruited to receive PegLiposomal Doxorubicin (PLD) in a continuous i. v. infusion of at least 60 minutes at a dose of 40 mg/m2 on Day 1, followed by a 30-minute i. v. carboplatin infusion according to AUC 6 (formula devised by Calvert et al).
Patients will get outpatients treatment. At screening the patients' eligibility will be assessed, their baseline and demographic characteristics obtained, and baseline values for the effect variables collected. Patients with measurable lesions, non-measurable lesions or histological documentation will be included into this trial. Measurable lesion and non-measurable lesions will be documented by x-ray, ultrasound, computed tomography or MRI.
The patients' safety will be monitored during therapy until recovery of toxicities.
In patients with measurable lesions at baseline, the (post)-treatment values for effect according to the RECIST criteria will be collected as shown in table 6. CR, PR and SD have to be confirmed by a repeat measurement after an interval of at least four weeks.

- •At least 18 years of age
- •Estimated life expectancy above 12 weeks
- •At least 3 weeks since major surgery
- •Appropriate hematologic, renal and hepatic function in accordance with the following definitions:
