A randomized phase II trial of docetaxel and doxorubicin in treatment for patients with non-small-cell lung cancer who have failed previous platinum-based chemotherapy / 中华肿瘤杂志

<p><b>OBJECTIVE</b>The aim of this study was to evaluate the efficacy, toxicity and safety of doxorubicin combined with domestically produced docetaxel versus with taxotere, and to investigate whether these two regimens result in similar outcomes in the treatment for non-small-cell lung cancer (NSCLC) patients who failed previous platinum-based chemotherapy.</p><p><b>METHODS</b>Eighty-eight NSCLC patients were enrolled into this clinical phase II trial. The patients randomly received either domestic docetaxel (study arm) or taxotere (control arm) at a dose of 70 mg/m2 on D2, while doxorubicin at a dose of 40 mg/m2 on D1 was administered in both groups. It was repeated every 3 weeks, totally for three cycles. No granulocyte colony-stimulating factor was used to prevent granulocytopenia. The response rate and toxicity were evaluated using World Health Organization toxicity scale and Karnofsky performance status scale.</p><p><b>RESULTS</b>Of the 88 patients, 81 were evaluable in terms of efficacy. There was no complete responder in this series. The response rate (RR) was 17.1% in the study arm versus 7.5% in the control arm, and the clinical benefit rate (CBR) was 80.5% in the study group versus 72.5% in the control group. The most frequent grade 3 or 4 toxicities were neutropenia, leucopenia and gastrointestinal symptoms. Other toxicities such as alopecia and vomiting were mild and generally well tolerated. No fluid retention was noticed.</p><p><b>CONCLUSION</b>The administration of doxorubicin 40 mg/m2 on D1 combined with domestic docetaxel 70 mg/m2 on D2 is proved to be as effective and tolerable as with taxotere. The domestic drug docetaxel may be considered as an alternative for patients with non-small-cell lung cancer who failed previous platinum-based chemotherapy.</p>

Phase II multicenter clinical trial of nedaplatin in the treatment of malignant tumors / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate and compare the efficacy and safety of Nedaplatin (NDP)-based regimen and cisplatin (DDP)-based regimen for head and neck squamous cell carcinoma (HNSCC), non-small cell lung cancer (NSCLC), esophageal cancer and ovary epithelial cell carcinoma.</p><p><b>METHODS</b>Single agent group: NDP was administered at a dose of 100 mg/m(2) on D1, every 3 weeks for at least 2 cycles. Combination chemotherapy group: combined with 5-Fu, NVB, VDS + 5-Fu, PTX or CTX respectively, NDP 80 mg/m(2) on D1 or DDP 30 mg/m(2) on D1-3, every 3 weeks for at least 2 cycles was given.</p><p><b>RESULTS</b>Of 237 patients in this trial, 37 were treated by single Nedaplatin, 139 by NDP-based regimen, 61 by DDP-based regimen in the control group. The response rate of single Nedaplatin chemotherapy for advanced NSCLC was 10.5% (2/19), for ovary carcinoma (1/3) and HNSCC (1/1). For NSCLC and ovary carcinoma patients who had failed in the previous DDP-based chemotherapy, the response rates by single NDP chemotherapy were still 9.1% and 33.3%. The response rate of NDP-based combination regimen for NSCLC, ovary carcinoma, HNSCC and esophageal cancer was 33.9% (21/62), 44.8% (13/29), 20.0% (3/15) and 18.2% (4/22), respectively, which was not statistically different from the rate of controlled group treated by DDP-based regimen. For chemonaive NSCLC, the effect of NDP-based combination regimen (35.7%) was significantly superior to the effect of DDP-based regimen (17.1%) (P = 0.045). The most common adverse events of nedaplatin were myelosuppression (leukopenia, thrombocytopenia, anemia), nausea and vomiting. The myelosuppression and renal toxicity of NDP-based regimen were similar to that of DDP-based regimen, but vomiting was milder than that of DDP-based regimen (54% vs. 75.4%), and grade I/II liver toxicity was more common in the NDP-based regimen than in DDP-based regimen (10.8% vs. 0).</p><p><b>CONCLUSION</b>Nedaplatin is effective in the treatment for HNSCC, NSCLC and ovary carcinoma. Compared with the control group treated by DDP-based regimen, nedaplatin-based combination chemotherapy has similar effect on HNSCC, NSCLC, ovary carcinoma and esophageal cancer. Gastrointestinal reaction of nedaplatin is milder than that of cisplatin but the liver function during chemotherapy must be monitored closely.</p>

Docetaxel in the treatment of advanced breast cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy, toxicity and safety of an new domestic docetaxel in the treatment of pretreated advanced breast cancer.</p><p><b>METHODS</b>Fourty-four breast cancer patients who had failed in first-line chemotherapy were included in this trial. They received docetaxel as the second-line chemotherapy. Docetaxel was administered alone at a dose of 70 mg/m2 every 3 weeks. The use of granulocyte colony-stimulating factor to prevent granulocytopenia was not permitted. The response rate and toxicity were evaluated by World Health Organization toxicity scale and performance status by Karnofsky scale.</p><p><b>RESULTS</b>Of the 41 evaluable patients, 4 achieved complete response and 14 partial remission, with a response rate and clinical benefit rate of 43.9% and 85.4%, respectively. Grade 3 or grade 4 neutropenia developed in 42.9%, alopecia in 7.1% and vomiting in 4.8% of these patients. Fluid retention was not observed in this series.</p><p><b>CONCLUSION</b>Three-week administration of docetaxel alone at a dose of 70 mg/m2 is effective and tolerable. It provides an alternative for the pretreated advanced breast cancer patients.</p>
