Fulltext PDFLung cancer is responsible for 12.9% of all new cancer cases diagnosed globally and is responsible for 19.5% of all cancer-related deaths. The percentage of patients presenting as stage IV disease increased from 38.7% between 1994 and 1998 to 47.2% between 1999 and 2004 to 54.8% between 2008 to 2017. Histology has been found to be prognostic for survival in stage 4 lung cancer. Large Cell Neuroendocrine Carcinoma (LCNEC) is a subtype of Non-Small Cell Lung Cancer (NSCLC) and accounts for approximately 1.6% to 3.1% of all lung cancer. LCNEC is now recognized as a histologically high-grade non-small cell carcinoma by WHO, categorized as a variant of large cell carcinoma. It has a distant metastasis rate of 65% and poor prognosis even in early stages, with survival rates similar to Small-Cell Lung Carcinomas (SCCs). The life expectancy of stage IV LCNEC with distant metastasis was estimated at around 6 months.
We report a case of 49 years old male with carcinoma lung harboring LCNEC histology, who responded very well to Anti-EGFR TKI Gefitinib with a PFS of 14 months and ongoing with a partial response to disease.
