Combined immune checkpoint blockade (ICB) is effective therapy for renal cell carcinoma (RCC). However, the dynamic changes in circulating B cells induced by combined ICB have not been clarified. The present study prospectively examined 22 patients scheduled to receive ICB for unresectable or metastatic RCC between March 2018 and August 2021.

Although the neutrophil to lymphocyte ratio (NLR) was reported to be a predictive biomarker for clinical outcomes in various types of cancer, including recurrent or metastatic head and neck cancer (R/M HNSCC) treated with nivolumab, the usefulness of the pretreatment C-reactive protein/albumin ratio (CAR) as a prognostic marker remains to be clarified. This study aimed to analyze the clinical usability of the CAR in comparison with that of the NLR. 46 R/M HNSCC patients treated with nivolumab were retrospectively analyzed.

Article Synopsis
  • Advanced or recurrent gastric cancer in elderly patients is often treated with fluoropyrimidine (S-1) alone for better tolerability, while the standard treatment is a combination with platinum (cisplatin).
  • A multicenter study analyzed data from 444 patients aged 70 and older, comparing outcomes between those treated with S-1 only and those receiving the SP combination therapy, utilizing propensity score matching to balance patient characteristics.
  • The results showed no significant survival differences between the two groups, but the SP group experienced more severe adverse events, prompting further research to optimize treatment strategies for elderly patients.

Background: Salvage-line regorafenib monotherapy exhibited a marked survival benefit for metastatic colorectal cancer (mCRC). However, the toxicity of this regimen has resulted in the clinical use of a reduced dose of regorafenib.

Patients And Methods: Thirty-two Japanese mCRC patients (median age=61 years) who had been treated with regorafenib were retrospectively examined.
