[0080]Analysis of relapsed NSCLC and generation of gefitinib-resistant NCI-H1 650 cells. After obtaining appropriate consent, autopsies were performed to obtain clinical samples of recurrent NSCLC. Following analysis of non-clonal PCR products, the entire kinase domain of EGFR was sequenced. Multiplex clones of exon 20 were sequenced to detect codon 790. By automated sequencing of single exons using dye terminator chemistry (BIGDYE version 1.1, Applied Biosystems) and flanking intronic (flanking...

Abstract

The present invention is directed to methods for the treatment of gefitinib and / or erlotinib resistant cancer. An individual with cancer is monitored for cancer progression following treatment with gefitinib and / or erlotinib. Progression of the cancer is indicative that the cancer is resistant to gefitinib and / or erlotinib. Once progression of cancer is noted, the subject is administered a pharmaceutical composition comprising an irreversible epidermal growth factor receptor (EGFR) inhibitor. In preferred embodiments, the irreversible EGFR inhibitor is EKB-569, HKI-272 and HKI-357.

Description

[0001] This application is a divisional application of an invention application with the application date of February 02, 2006, the application number 201210328133.2, and the title "Method for Treating Gefitinib-resistant Cancer"; the application date is February 02, 2006 , the application number is 201210328133.2, and the invention application titled "method for the treatment of gefitinib-resistant cancer" is the application date of February 02, 2006, the application number is 200680011003.9, and the title of the invention is "the treatment of gefitinib-resistant cancer". A divisional application of the invention application of "method for drug-induced cancer". Background of the invention [0002] Epithelial cell carcinomas, eg, prostate, breast, colon, lung, pancreas, ovary, spleen, testis, thymus, etc., are diseases characterized by abnormal accelerated growth of epithelial cells. This accelerated growth initially causes tumor formation. Finally, metastases to different or...
