Preliminary result of multi-center clinical trial on the docetaxel, 5-Fu and DDP in the treatment of advanced, recurrent or metastatic nasopharyngeal carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>This clinical study was designed to evaluate the efficacy and toxicity of the combined regimen of docetaxel, 5-Fu and DDP (TPF) in the treatment of advanced or relapsed nasopharyngeal carcinoma (NPC).</p><p><b>METHODS</b>Fifty-six patients with newly diagnosed or recurrent/metastatic NPC following chemotherapy or radiotherapy were enrolled. Both docetaxel and DDP were administered intravenously for 6 hours at the dose of 70 mg/m2 on D1. 5-Fu was given at a dose of 400-500 mg/m2 for 6 hours from D1 to D5. Dexamethasone was routinely administered before injection of docetaxel. This combination was repeated every 3 to 4 weeks, and continued for 4-6 cycles or until PD for the responders.</p><p><b>RESULTS</b>Fifty-one (91.1%) patients were evaluable for response assessment. The response rate for whole group was 72.5% (37/51) with a CR rate of 9.8% (5/51). The stable disease accounted for 17.6% (9/51). There were 17(30.4%) chemotherapy-naïve patients. The overall response rate in those was 82.4% with a CR rate of 29.4%. However, the response rate for previously treated patients was 64.7% without CR. Twelve patients had progressed disease, including 5 (8.9%) died of disease progression with a median follow-up of 11 month (ranged from 1 to 19 months). Totally, 196 courses of chemotherapy were administered. The major toxicity was myelosupression, nausea/vomiting. The incidence of leucopenia was 48% with 22.2% of these in NCI grade II or IV. But only 2 patients (3.6%) experienced leucopenia with a fever. Other mild toxicities including alopecia, asthenia, mucositis and diarrhea were also observed.</p><p><b>CONCLUSION</b>Our preliminary outcome shows docetaxel, 5-Fu and DDP combination is effective and safe for the patients with advanced or relapsed nasopharyngeal carcinoma. But further clinical study is warranted.</p>

Clinical trial on exemestane in the treatment of postmenopausal women with advanced breast cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the response rate and adverse reactions of exemestane (a new aromatase inactivator) in the treatment of postmenopausal women with advanced breast cancer.</p><p><b>METHODS</b>One hundred and seventy-three patients with advanced breast cancer entered this study with two patients excluded because of postmenopausal time being less than one year. Therefore, 173 patients could be evaluated for adverse events and 171 patients could be evaluated for efficacy. Exemestane, 25 mg orally daily for 4 weeks as one cycle was given.</p><p><b>RESULTS</b>In the 171 patients evaluated for efficacy, 4 (2.3%) experienced a complete response (CR) and 40 (23.4%) a partial response (PR), with the overall response rate of 25.7%. Ninety patients (52.6%) had stable disease (SD), with 25 having SD for at least 24 weeks. The clinical benefit (CR + PR + SD > or = 24 weeks) was shown in 69 (40.4%) patients. Progressive disease (PD) was shown in 37 (21.6%) patients. The untreated patients had a higher objective response rate (33.8%) than the retreated ones (18.1%) with significant difference (P = 0.019 7). The response rates for soft-tissue, bone involvement and visceral metastasis were 32.8%, 23.9%, and 12.4% (P = 0.002). There was no significant difference in different ages, time of menopause, disease-free interval or receptor status (P > 0.05). Drug-related adverse events were gastric discomfort (17.9%), malaise (17.9%), nausea (13.9%), hot flushes (11.0%) and dysphoria (5.8%). Other side reactions and abnormal laboratory parameters were observed occasionally which were irrelevant.</p><p><b>CONCLUSION</b>Exemestane can be used to treat postmenopausal women with advanced breast cancer giving only mild adverse reactions which are well tolerated.</p>
