OBJECTIVE: To systematically review the relationship of clinical efficacy between XPD Lys751Gln (A/C), XPD Asp312Asn (G/A) and platinum-based chemotherapy in patients with advanced non-small cell lung cancer (NSCLC), and provide evidence-based reference for clinical treatment. METHODS: Retrieved from PubMed, Cochrane Library, EMBase, Medline, CJFD,VIP database and WanFang database, studies about the effects of XPD Lys751Gln and XPD Asp312Asn polymorphism on effectiveness, clinical outcomes and adverse drug reaction of platinum-based chemotherapy in advanced NSCLC patients were collected, and Meta-analysis was performed by using Rev Man 5.3 software. RESULTS: Totally 30 studies were included, involving 5 028 patients. Genetic testing showed that XPD Lys751Gln divided into mutant gene (Lys/Gln + Gln / Gln) and wild-type gene (Lys/Lys), while XPD Asp312Asn divided into mutant gene (Asp /Asn + Asn/Asn) and wild-type gene (Asp/Asp). Results of Meta-analysis showed, the progression-free survival (PFS) of Lys/Gln+Gln/Gln patients with platinum in XPD Lys751Gln polymorphism was obviously lower than Lys/Lys patients [OR=-1.12,95%CI(-1.73,-0.50),P<0.001], while there was no significant difference in the chemotherapy effectiveness and total survival period. The effective rate of Asp/Asn+Asn/Asn patients for platinum in XPD Asp312Asn polymorphism was lower than Asp/Asp patients [OR=0.80, 95%CI(0.68, 0.96),P=0.02], while there was no significant difference in the total survival period and PFS. Meanwhile, the incidence of Ⅲ-Ⅳ level gastrointestinal adverse reactions of Lys/Gln+Gln/Gln with platinum in XPD Lys751Gln polymorphism was higher than Lys/Lys patients [OR=0.43, 95%CI(0.20,0.94),P=0.03], and there was no significant difference in Ⅲ-Ⅳ level blood system adverse reactions. CONCLUSIONS: XPD Lys751Gln polymorphism may be associated with PFS and Ⅲ-Ⅳ level gastrointestinal adverse reactions for advanced NSCLC patients with platinum-based chemotherapy, while XPD Asp312Asn polymorphism may have effect on platinum-based chemotherapy, both of them may be as estimate the chemotherapy effect and prognosis detection index of platinum-based chemotherapy.
