Background:
This study investigated the roles of single nucleotide variants (SNVs) in genes of CDDP metabolism and their association with kidney dysfunction in patients with head and neck squamous cell carcinoma (HNSCC).
Methods:
A total of 109 patients with locally advanced HNSCC, treated with CDDP, had renal function evaluated by serum creatinine level and CKD-EPI formula, and underwent genotyping by polymerase chain reaction.
Results:
Patients with GSTT1 present and ERCC1 c.354CT or TT genotypes showed 4.94% and 8.94% renal function reduction, respectively. GSTT1 present with TP53 c.215G>C (17.67%), GSTP1 c.313A>G with ERCC1 c.354C>T (17.57%), GSTP1 c.313A>G with MLH1 c.93G>A (12.49%), GSTP1 c.313A>G with MSH3 c.3133A>G (12.19%), ERCC1 c.354C>T with MLH1 c.93G>A (18.85%) and ERCC1 c.354C>T with MSH3 c.3133A>G (13.38%) combined genotypes were also associated with substantial declines in renal function.
Conclusions:
Our data suggest that isolated and combined SNVs in genes enrolled in CDDP metabolism can be used to select patients for treatments that spare the kidneys from adverse effects.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
