Background:
The impact of glucocorticoid administration for adverse events (AEs), including immune-related AEs, on the effectiveness of immune checkpoint inhibitor (ICI) combination therapy for advanced renal cell carcinoma (RCC) remains unknown.
Objectives:
To clarify the prognostic impact of glucocorticoid use for AEs during first-line ICI combination therapy for advanced RCC.
Patients And Methods:
We retrospectively evaluated data from 194 patients who received dual ICI combination therapy [i.e., immunotherapy (IO)-IO] or combinations of ICIs with tyrosine kinase inhibitors (TKIs) as first-line therapy. The patients were divided into two groups according to the history of glucocorticoid administration in each treatment group. Survival based on glucocorticoid administration was assessed.
Results:
A total of 101 (52.0%) and 93 (48.0%) patients received IO-IO and IO-TKI combination therapy, respectively. Glucocorticoids were administered to 46 (46%) and 22 (24%) patients in the IO-IO and IO-TKI groups, respectively. In the IO-IO group, progression-free survival (PFS) and overall survival (OS) were significantly longer in patients with glucocorticoid administration than in those without administration (median PFS: 14.4 versus 3.45 months, p = 0.0005; median OS: 77.6 versus 33.9 months, p = 0.0025). Multivariable analysis showed that glucocorticoid administration was an independent predictor of longer PFS (hazard ratio: 0.43, p = 0.0005) and OS (hazard ratio: 0.35, p = 0.0067) after adjustment for covariates. In the IO-TKI group, neither PFS nor OS significantly differed between patients treated with and without glucocorticoid administration (PFS: p = 0.0872, OS: p = 0.216).
Conclusions:
Glucocorticoid administration did not negatively impact the effectiveness of ICI combination therapy for RCC, prompting glucocorticoid treatment use when AEs develop.

01:11Renal 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...

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...
