Background: Non-small cell lung cancer (NSCLC) is classified in two main categories: adenocarcinoma (AC), which includes bronchioloalveolar carcinoma (BAC), and squamous cell carcinoma (SCC). Activating mutations and increased copy number of the EGFR gene have been reported in tumors from patients with NSCLC with increased response rate to tyrosine kinase inhibitors (TKIs). There is […]

Background: Irinotecan (CPT-11) is currently used as first- or second-line treatment for colorectal cancer, either alone or in combination with 5-fluorouracil based regimens. UDP-glucuronosyltransferase 1A1 (UGT1A1) catalyzes the inactivation of SN-38, the active metabolite of irinotecan, through glucuronidation. UGT1A1*28, a polymorphic variant of this enzyme displaying an additional TA dinucleotide in the promoter TATA box, has been […]

Background: Activating mutations of the EGFR gene were identified in tumors from patients with non small cell lung cancer (NSCLC) that responded to therapy with tyrosine kinase inhibitors (TKIs). More recently, survival has been reported to significantly increase amongst patients carrying a […]
