The effect of chemotherapy on the different components of advanced carcinosarcomas (malignant mixed mesodermal tumors) of the female genital tract.

The effect of chemotherapy on the different components of uterine and ovarian carcinosarcoma is largely unknown. This report describes six patients with advanced carcinosarcoma, five of whom received 4 cycles of doxorubicin and ifosfamide (AI) directed at the sarcomatous component of the tumor. Responses in these five patients at second-look laparotomy were: one complete response, two partial responses (persistence of only the carcinomatous component), one stable disease, and one progressive disease (both components still present in both cases). Thereafter 4 cycles of a cisplatin-based regimen were scheduled. Response to the cisplatin-containing regimen was only evaluated clinically. The sixth patient (with no macroscopic disease left after initial surgery) received 6 cycles of a cisplatin-based chemotherapy from the onset and was found to be in complete response at relaparotomy. Median progression-free survival for all patients was 15 months and median survival 21 months. A literature survey showed that carcinosarcoma differs from adult soft tissue sarcomas with respect to responsiveness to chemotherapy. Cisplatin and ifosfamide are active as single agents, whereas the response to single-agent doxorubicin seems to be lower. The data suggest, however, that superior response rates and increased survival times are achieved with cisplatin/doxorubicin-based chemotherapy. The sensitivity of carcinosarcoma to cisplatin supports the recent view that carcinosarcoma of the female genital tract is possibly a high grade carcinoma with metaplastic sarcomatous elements.

[Malignant mixed mesodermal tumor of the ovary. A review of the literature apropos of a case with immunohistochemical study].

A very large left ovarian tumor in a 76 year old woman, on microscopic study, consisted of an epithelial component: both glandular and squamous, and a sarcomatous component: both cartilage and striated muscle. Epithelial and sarcomatous patterns were intermingled in a spindle-cell stroma. Immunohistochemical study revealed, in these spindle cells, cytokeratin-positive anaplastic epithelial structures and vimentin-positive mesenchymal structures. A review of the literature concerning this rare ovarian tumor especially including cases with a immunohistochemical study is added. However, immunohistochemical study does not allow histogenetic interpretation.
