Abstract
Cisplatin (CDDP) chemotherapy associated with radiation (RT) has been used in advanced head and neck squamous cell carcinoma (HNSCC) patients, and vomiting is a common side effect during treatment. This prospective study aimed to identify the roles of GSTM1 and GSTT1 (presents or nulls), GSTP1 c.313A>G, XPC c.2815A>C, XPD c.934G>A and c.2251A>C, XPF c.2505T>C, ERCC1 c.354C>T, MLH1 c.-93G>A, MSH2 c.211+9C>G, MSH3 c.3133G>A, EXO1 c.1765G>A, TP53 c.215G>C, CASP3 c.-1191A>G and c.-1168G>T, CASP9 c.-1339A>G, CASP8 c.-937_-932delAGTAAG, FAS c.-1378G>A and c.-671A>G, and FASL c.-157-687C>T single nucleotide polymorphisms, involved in CDDP metabolism, in vomiting severity in 88 HNSCC patients treated with CDDP and RT. Ondansetron and dexamethasone were administered as antiemetic therapy. Patients with GSTP1 c.313AG or GG genotype alone and combined with XPD c.934GA or AA, XPF c.2505TC or CC, and CASP9 c.-1339AG or GG genotypes had 4.28, 5.00, 5.45, and 5.38 more chances of presenting moderate/severe vomiting than patients with others genotypes. Our data suggest, for the first time, that inherited abnormality in apoptosis pathway alone or combined with inherited abnormalities in DNA repair pathway, are capable of modulating emesis in HNSCC patients under CDDP chemoradiation and may be used for selecting patients who should receive preemptive antiemetic therapy.
