A common deletion polymorphism within B-cell chronic lymphocytic leukemia-lymphoma like 11 gene (BIM) was deemed to be a genetic cause leading to compromised kinase inhibitor therapeutic efficacy in cancer individuals. However, the results reported were not consistent. Thus, a comprehensive meta-analysis containing 12 eligible studies including 1,532 Asian patients was conducted to investigate a steady and reliable conclusion. The results showed that BIM deletion polymorphism was significantly associated with tyrosine kinase inhibitor (TKI) clinical efficacy in term of response rate (Ph = 0.349, HR = 0.438, 95%CI = 0.274-0.699) and disease control rate (Ph = 0.941, HR = 0.370, 95%CI = 0.202-0.678) in EGFR-mutated NSCLC population, not in CML and HCC subgroups. Additionally, EGFR-mutated NSCLC patient harbored BIM deletion polymorphism was associated with a shorter progression-free survival (PFS) than those with BIM wild polymorphism (Ph = 0.580, adjusted HR = 2.194, 95%CI = 1.710-2.814). However, no significant association was examined between BIM deletion polymorphism and overall survival (OS) and toxic adverse events in EGFR-mutated NSCLC population and it was not associated with PFS and OS in HCC subgroup. These findings revealed that BIM deletion polymorphism might be a genetic cause of intrinsic resistance to TKI therapy and it could be emerged as an independent predictor to identify patients who would benefit from TKI targeted therapy in EGFR-mutated NSCLC.

The diagnosis of different types of cancer in a single patient has been appeared in the field in some case reports involving different categories of cancer types either appeared at the same time (synchronous) or subsequently (meta-synchronous). The aim of this report is to present this interesting case of male patient who was under treatment of CML then T-lymphoblastic lymphoma and HCC discovered subsequently. CML, Lymphoma and HCC are arising from different lines of cells with different biology and cytogenetic criteria. CML and acute lymphoblastic leukemia may occur together in cases of blastic crisis of CML. But, they rarely occur together as separate multiple malignancies especially without any history of exposure to ionizing radiation, chemotherapy or transplantation.
