Mucinous BAC, in contrast, is much more highly associated with K-ras mutations and wild-type EGFR, and are thus usually insensitive to the EGFR tyrosine kinase inhibitors. [19] In fact, there is some evidence that suggests that the administration of EGFR-pathway inhibitors to patients with K-ras mutated BAC may even be harmful.
Also, patients who tested negative for EML4/ALK fusion had a response rate to crizotinib of up to 35%. [20] According to patient advocacy group ALK Positive, a study in December 2018 found that the median survival for people with stage 4 (IV) ALK-positive lung cancer was 6.8 years with the right care.

Abnormal duplication of the EGFR gene is a relatively infrequent phenomenon in SCL (>/= 4 copies in >/= 40% of cells in 5/22). [2] Overexpression of the EGFR protein occurs in nearly all cases (22/22). [2] Mutations of the EGFR gene are relatively rare (0/23). [2] K-ras mutations found in 8/22 cases (Gly12Cys in 6 cases and Gly12Val in 2 cases ...
Erlotinib (Tarceva), another EGFR tyrosine kinase inhibitor, increased survival in non-small cell lung cancer [21] and was approved by the FDA in 2004 for second-line treatment of advanced non-small cell lung carcinoma. [22]
Combined small cell lung carcinoma (or c-SCLC) is a form of multiphasic lung cancer that is diagnosed by a pathologist when a malignant tumor, arising from transformed cells originating in lung tissue, contains a component of small cell lung carcinoma (SCLC) mixed with one or more components of any histological variant of non-small cell lung carcinoma (NSCLC) in any relative proportion.
Mutations that lead to EGFR overexpression (known as upregulation or amplification) have been associated with a number of cancers, including adenocarcinoma of the lung (40% of cases), anal cancers, [18] glioblastoma (50%) and epithelian tumors of the head and neck (80–100%). [19]
