RESUMO

Dedifferentiated chondrosarcoma (DDCS) is a rare but highly malignant primary bone neoplasm, which is resistant to radiotherapy and chemotherapy. There remains uncertainly as to the best treatment of this disease and how to improve its prognosis. In this paper we reported a case of DDCS and reviewed the related literatures in order to provide references to throw a light on the histogenesis, diagnosis and therapy of this disease.

RESUMO

<p><b>OBJECTIVE</b>The aim of this study was to compare the results of different combined chemotherapy regimens and to find the best regimen for metastatic nasopharyngeal carcinoma (NPC), and determine its prognostic factors.</p><p><b>METHODS</b>The clinical data of 171 patients with pathologically proven metastatic NPC were retrospectively analyzed. Of them, 26 were treated with best support care (BSC group), 92 with platinum-based regimen of two drugs (FP group: 5-Fu and cisplatin; TP group: paclitaxel and cisplatin; DP group: docetaxel and cisplatin), and 53 with platinum-based regimen of three-drugs (TFP group: FP plus paclitaxel, DFP group: FP plus doxtale).</p><p><b>RESULTS</b>The response rate (RR) in the three-drug regimens was significantly higher than that in the two-drug regimen (84.9% vs. 52.2%, P = 0.000), however, grade III approximately IV myelosuppression in the three-drug regimen group was also significantly higher than that in the two-drug regimen (58.5% vs. 27.2%, P = 0.000). Among the groups treated with platinum-based combination regimens of either two drugs or three drugs, no significant differences were observed in RR (P = 0.967, P = 0.400) or median survival time (MST) (P = 0.278, P = 0.413). The MST and one-year survival rate were 4.0 months, 13.2 months and 15.0 months, 24.0%, 64.1% and 70.3% in the BSC group, two-drug group and three-drug group, respectively. The MST in the chemotherapy group was significantly longer than that in BSC group (P = 0.000). Cox multivariate regression analysis showed that Karnovsky performance scores, time to progression or chemotherapy cycles were independent prognostic factors (P < 0.05).</p><p><b>CONCLUSION</b>Chemotherapy can improve the survival of metastatic NPC. Platinum-based combination regimen with two drugs is still the standard treatment. The combination regimens with three drugs can increase the RR, but no survival benefit can be achieved for its high toxicity.</p>
