Abstract:
Elderly individuals represent a consistent proportion of all cancer patients. However, they are under-represented in clinical trials. The present study evaluated the actual tolerability of sunitinib in elderly Japanese patients with advanced renal cell carcinoma (RCC). A total of 56 consecutive patients with advanced RCC treated with sunitinib were enrolled. Patients were divided into two groups according to their age at the time of sunitinib initiation: i) elderly cohort (≥70 years); and ii) younger cohort (<70 years). Disease control rate, progression-free survival, overall survival and relative dose intensity (RDI) were compared between the two cohorts. The elderly cohort comprised of 14 patients (25.0%), and the younger cohort included 42 patients (75.0%). The elderly cohort had a significantly higher Charlson comorbidity index than the younger cohort (mean, 9.7 vs. 7.9; P<0.0001). Disease control rate, progression-free survival, and overall survival were not significantly different. The elderly cohort had a significantly lower RDI than the younger cohort (mean, 51.7 vs. 65.0%; P=0.0340). Thus, treatment with sunitinib is feasible and effective in elderly Japanese patients with advanced RCC. However, the RDI of elderly patients was significantly lower, and a relatively low dose of sunitinib provided optimal therapeutic efficacy.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
