Successful pre-surgical treatment with carboplatin and gemcitabine chemotherapy for a patient with muscle-invasive bladder cancer and severe renal dysfunction.

Radical cystectomy is the standard treatment for muscle-invasive bladder cancer, and pre-surgical treatment can improve survival. Carboplatin and gemcitabine chemotherapy is considered an effective, safe treatment for patients ineligible for cisplatin-based chemotherapy owing to reduced renal function. However, there is limited evidence on pre-surgical treatment with carboplatin and gemcitabine chemotherapy with glomerular filtration rates < 30 mL/min.

Fulminant Type 1 Diabetes Mellitus Caused by Long-Term Nivolumab Administration Followed by Nivolumab plus Cabozantinib Combination.

Nivolumab, an immune checkpoint inhibitor (ICI), is now used to treat many advanced cancers, including non-small cell lung cancer (NSCLC) and renal cancer. Immune-related adverse events are characteristic side effects of ICIs. Among them, fulminant type 1 diabetes mellitus is an infrequent but potentially life-threatening and clinically significant concern.
