Temozolomide in combination with fotemustine in patients with metastatic melanoma

Purpose  Temozolomide and fotemustine are both active drugs for treating metastatic melanoma. The present study was designed to assess the efficacy and safety of combination therapy with temozolomide + fotemustine in patients with metastatic melanoma. Methods  Forty patients (median age 50.5 and 22 males) with pathologically confirmed, unresectable, AJCO stage IV melanoma were enrolled into the study. The primary endpoints were tumor response and safety. Patients received oral temozolomide 125 mg/m² on days 1–7 and intravenous fotemustine 80 mg/m² on day 3 every 3 weeks. Results  Fourteen (35%) patients achieved an objective response, including 3 (7.5%) complete and 11 (27.5%) partial responses. Median overall survival time was 6.7 months and 6-month survival rate was 57.4%. Myelosupression, particularly thrombocytopenia, was the primary toxicity. Conclusion  The regimen, temozolomide combined with fotemustine, is an active and moderately safe first-line chemotherapy regimen with acceptable and easily manageable toxicities in patients with metastatic melanoma.     

Docetaxel in combination with dacarbazine in patients with advanced melanoma

OBJECTIVES: The number of agents that are active in patients with metastatic melanoma is limited and cure is not a realistic objective for treatment at this stage. The aim of the study was to evaluate the efficacy and safety of new combination regimen cosisting of docetaxel and dacarbazine (DTIC), as first-line chemotherapy, in patients with advanced melanoma. PATIENTS AND METHODS: Patients with advanced melanoma (including cerebral metastases) were eligible. Docetaxel 80 mg/m(2), i.v. over 1 h infusion on day 1, and DTIC 400 mg/m(2), i.v. over 45 min on days 1 and 2, were given every 21 days, for six cycles. All patients were premedicated, prior to each course, with methylprednisolone per os. RESULTS: Forty-one patients entered the study. Thirty-nine were assessable for response and 40 for toxicity. Objective responses were seen in 10 patients (24% of the eligible; 95% CI = 12.4-40.3%, 26% of the assessable and 28% of patients with cerebral metastases were excluded). Three of them achieved a complete response (7%; 95% CI = 1.5-19.9) and 7 a partial response (17%; 95% CI = 7.1-32.0), while 8 patients demonstrated stabilization of their disease (20%; 95% CI = 8.8-34.9). After a median follow-up of 20 months, the median time to progression was 7 months (range 0.5-22) and the median survival was 10 months (1-24+). The main toxicity (G3-4) was neutropenia which occurred in 8/40 (20%) patients. Additional patients had reversible G3-4 toxicities including alopecia, nausea and vomiting and fatigue; 3 of them presented mild to moderate hypersensitivity reactions to docetaxel. No toxic death was noted. CONCLUSIONS: The combination of docetaxel and DTIC is active and well tolerated in patients with advanced melanoma. While this combination is at least as effective as various combination regimens, it does not differ from that reported for single-agent DTIC.     

Preoperative treatment with bevacizumab in combination with chemotherapy in patients with unresectable metastatic colorectal carcinoma

Purpose

This prospective observational study assessed the efficacy of bevacizumab in combination with chemotherapy as preoperative treatment to downsize tumours for radical resection in patients with unresectable metastatic colorectal cancer (mCRC).

Patients/methods

Patients with mCRC initially unresectable according to predefined criteria were included. Preoperative treatment consisted of bevacizumab (5 mg/kg) combined with oxaliplatin- or irinotecan-based chemotherapy, which was followed by surgery in patients showing clinical benefit. Resection rate was the primary endpoint. Response rate (RR) and clinical benefit of preoperative chemotherapy, and overall survival (OS) were secondary endpoints.

Results

A total of 120 eligible patients were included and received preoperative treatment. Chemotherapy was irinotecan-based in 73 (61 %) patients, oxaliplatin-based in 25 (21 %) and 22 (18 %) patients received more than one line. A RR of 30 % and a clinical benefit rate of 73 % were observed with preoperative chemotherapy. Metastatic resection was possible in 61 (51 %) patients. Median OS was 33 months (95 % CI 31–NA months) for patients undergoing surgery, and 15 months (95 % CI 11–25 months) in non-operated patients. Thirty-five patients experienced 59 postoperative complications (morbidity rate 57 %).

Conclusion

Preoperative bevacizumab-based chemotherapy offers a high surgical rescue rate in patients with initially unresectable mCRC.     

Concomitant radiotherapy with chemotherapy in patients with glioblastoma

Glioblastomas are the most frequent and the most aggressive primary brain tumors in adults. Therapeutic strategy is challenging because of radioresistance and chemoresistance explaining the poor prognosis (median survival of 12 months). Standard therapy consisted until recently of surgery and postoperative radiotherapy while the impact of chemotherapy (investigated as adjuvant, neo adjuvant therapy or concomitant with irradiation) was a matter of debate. However a recent phase III study has concluded to the benefit of adjuvant temozolomide administered during and after radiotherapy. This strategy is yet to become a standard.     

再放疗并同步使用Docetaxel在鼻咽癌放疗后复发病人中的应用

目的:不能手术切除的鼻咽癌放疗后再复发的病人,其治疗困难,化疗疗效差,而单独再放疗只能挽救一小部分病人,本文探讨再放疗并同步使用多西紫彬醇(Docetaxel)在鼻咽癌首次放疗后复发病人中可行性及毒副反应,并评价其疗效。方法:对11例鼻咽癌足量放疗后经组织病理学证实复发、而无法行手术及腔内放疗的患者进行了同步放化疗。放疗采用三维适形放疗,外照射鼻咽部,分次量为1.8Gy,总剂量为36Gy-39.6Gy。化疗采用Docetaxel,15mg/m2,每周一次,静脉滴注。结果:10%、33%的患者分别出现Ⅲ度、Ⅳ度皮肤反应,18%、10%的病人分别出现Ⅲ度、Ⅳ度黏膜反应,18%患者出现Ⅲ度恶心呕吐,27%的患者出现Ⅲ度-Ⅳ度白细胞下降,10%患者出现Ⅲ度血小板下降。1例患者因严重的黏膜反应致使治疗延迟2周。治疗结束后,9例(82%)患者达到CR,2例(18%)达到PR,反应率为100%。结论:对于放疗后局部复发的鼻咽癌患者,采用同步放化疗,3D-CRT同时每周使用Docetaxel是可行的,其毒性反应在可以接受的范围内,短期疗效显著。
