About

Despite the fact that a substantial response rate may be obtained in small-cell lung cancers (using double-drug chemotherapy: cisplatin-etoposide, PE), a cure remains an exception. More aggressive regimens remain controversial and recent attempts at increasing dose-intensity have been restricted to patients with a more favourable presentation.

Bevacizumab is a humanized monoclonal antibody which binds to VEGF (Vascular Endothelial Growth Factor). In association with double-drug standard chemotherapies, it has been proven that bevacizumab can improve survival of previously untreated advanced non-small-cell lung cancers (NSCLC), compared to chemotherapy without bevacizumab). Such promising effects on NSCLC deserve to be tested on small-cell lung cancers.

In this trial (IFCT-0802), standard chemotherapy (PCDE or PE) will be compared to experimental treatment (PCDE or PE + bevacizumab 7.5 mg/kg) for previously untreated SCLC patients.

• Symptomatic cerebral or meningeal metastasis
• Other cancer in progress or medical history of cancer in the five last years (excepted basal cell carcinoma or in situ cervical cancer of the uterus.
• Important surgical intervention (including surgical biopsy), traumatic lesion during 28 days before starting the treatment, or anticipation of an important surgical intervention during the study
