carboplatin and etoposide with or without oblimersen sodium in treating patients with extensive stage small cell lung cancer

Conditions: Extensive Stage Small Cell Lung Cancer; Recurrent Small Cell Lung Cancer

Summary: this phase ii trial studies how well carboplatin and etoposide with or without oblimersen sodium works in treating patients with extensive stage small cell lung cancer. drugs used in chemotherapy, such as carboplatin and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. biological therapies, such as oblimersen sodium, may stimulate the immune system in different ways and stop cancer cells from growing. giving carboplatin and etoposide together with oblimersen sodium may kill not tumor cells

primary objectives: i. to assess the percentage of patients with extensive stage small cell lung cancer treated with g3139 (oblimersen sodium), carboplatin, and etoposide who live longer than 12 months. secondary objectives: i. to assess the response rate of patients treated with g3139, carboplatin, and etoposide. ii. to assess the toxicity of the combination of g3139, carboplatin, and etoposide. iii. to compare the toxicity observed to that seen in a cohort of patients treated with carboplatin and etoposide alone. outline: patients are randomized to 1 of 2 treatment arms. arm i: patients receive oblimersen sodium intravenously (iv) continuously on days 1-8, carboplatin iv over 30 minutes on day 6, and etoposide iv over 60 minutes on days 6-8. treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. arm ii: patients receive carboplatin iv over 30 minutes on day 1 and etoposide iv over 60 minutes on days 1-3. treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. after completion of study treatment, patients are followed up every 3 months for 1 year, and then every 6 months for 2 years.

Eligibility criteria:
inclusion criteria: * all patients must have histologically or cytologically documented small cell carcinoma of the bronchus; those who are being considered for combined modality therapy with chemotherapy and radiation are not eligible for this study * the extensive disease classification for this protocol includes all patients with disease sites not defined as limited stage; limited stage disease category includes patients with disease restricted to one hemithorax with regional lymph node metastases, including hilar, ipsilateral and contralateral mediastinal, and/or ipsilateral supraclavicular nodes; extensive disease patients are defined as those patients with extrathoracic metastatic disease, malignant pleural effusion, bilateral or contralateral supraclavicular adenopathy or contralateral hilar adenopathy * no prior chemotherapy for small cell lung cancer (sclc) * radiation therapy must have been completed at least 1 week before initiation of protocol therapy * measurable disease is defined as having at least one lesion that can be accurately measured in at least one dimension; the longest diameter of the lesion must be \>= 20 mm with conventional techniques or \>= 10 mm with spiral computed tomography (ct) scan; lesions that are not considered measurable include the following: * bone lesions * leptomeningeal disease * ascites * pleural/pericardial effusion * abdominal masses that are not confirmed and followed by imaging techniques * cystic lesions * tumor lesions situated in a previously irradiated area * eastern cooperative oncology group (ecog) performance status 0-2 * non-pregnant and non-nursing * no active central nervous system (cns) metastases; patients with cns metastases will be eligible if they have completed a course of cns radiotherapy if clinically indicated and recover from the toxicity of radiotherapy prior to enrollment, with a minimum of one week after completion of radiation * no medical conditions such as uncontrolled infection (including human immunodeficiency virus \[hiv\]), psychiatric illness which would prevent the patient from giving informed consent, uncontrolled diabetes mellitus or cardiac disease which, in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient * no patients with a "currently active" second malignancy other than nonmelanoma skin cancers; patients are not considered to have a "currently active" malignancy if they have completed therapy and considered by their physician to be at less than 30% risk of relapse * granulocytes \>= 1,500/ul * platelet count \>= 100,000/ul * bilirubin within normal limits * aspartate aminotransferase (ast) (serum glutamic oxaloacetic transaminase \[sgot\]) =\< 2.5 x upper limits of normal * prothrombin time (pt) =\< 1.5 x upper limits of normal * partial thromboplastin time (ptt) =\< 1.5 x upper limits of normal * creatinine =\ = 60 ml/min
