Optimization for the Treatment of Advanced Pulmonary Large Cell Neuroendocrine Carcinoma

Optimization for the Treatment of Advanced Pulmonary Large Cell Neuroendocrine Carcinoma: a Prospective, Randomized, Open-label, Phase 2 Study

The primary endpoint is to compare the PFS (progress-free survival ) of etoposide plus carboplatin with paclitaxel combined with carboplatin as first-line treatment for advanced pulmonary large cell neuroendocrine carcinoma.

The primary endpoint is to compare the PFS (progress-free survival ) of etoposide plus carboplatin with paclitaxel combined with carboplatin as first-line treatment for advanced pulmonary large cell neuroendocrine carcinoma.

In addition, gene spectrum detection and Mini-PDX are applied for validation of pharmacodynamic.

Results of clinical trials and pharmacodynamic test will be analyzed to provide evidence for the precise treatment for LCNEC.

Inclusion Criteria:

• Stage IIIB or IV pulmonary large-cell neuroendocrine carcinoma confirmed by histology or cytology
• Estimated life expectancy over 3 months
• Performance status 0,1,2
• Signed informed consent
• Adequate organ functions: absolute neutrophil count (ANC) over 1,500 cells/mm3 (1.5 x 109/L); platelet count over100,000/mm3 (100 x 109/L); serum creatinine < 2.5 mg/dL (221 mmol/L); serum AST or ALT <5.0 x upper limit of normal (ULN); serum total bilirubin <2.0 mg/dL (34 mmol/L)

Exclusion Criteria:

• Thoracic radical radiotherapy within 28 days of the initiation of study drug therapy except for palliative radiotherapy
• Use of any standard/experimental anti-cancer drug therapy within 28 days of the initiation of study drug therapy
• Prior history of malignancies other than non-small cell lung cancer (except for basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix or breast) unless the subject has been free of the disease for > or = to 1 year
• Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
• Pregnant or lactating
• Patient with concurrent medical or psychiatric illness which would, in the opinion of the investigator, prevent compliance with the study
