Synergistic Occurrence of EGFR, ALK, and KRAS Gene Mutations in a Patient with Non-small Cell Lung Cancer (Adenocarcinoma). Indian Journal of Medical Sciences. 2019 Jan; 71(1): 45-480019-53591998-3654http://imsear.searo.who.int/handle/123456789/196532Lung cancer is a commonly diagnosed malignancy. Adenocarcinoma, a subgroup of non-small cell lung cancer, is the commonest form and presents in an advanced stage of the disease, leaving a limited treatment option. Response to the standard chemotherapy regimens is overall poor. We present a case of synergistic occurrence of triple gene mutations in a patient with well-diff erentiated adenocarcinoma lung treated at a tertiary cancer care center in North India.Non-small cell lung cancerEGFRALKKRASJournal ArticleIndiaDepartment of Medical Oncology, Rajiv Gandhi Cancer Institute and Research Centre, Delhi, IndiaDepartment of Research, Rajiv Gandhi Cancer Institute and Research Centre, Delhi, IndiaDepartment of Laboratory Services, Rajiv Gandhi Cancer Institute and Research Centre, Delhi, IndiaDepartment of Nuclear Medicine, Rajiv Gandhi Cancer Institute and Research Centre, Delhi, India
