Concurrent Chronic Myeloid Leukemia and Metastatic Renal Cell Carcinoma in a 61-year-old Female: Successful Treatment with Low-Dose Immunotherapy and Combination Targeted Therapy.

We report a rare case of a 61-year-old female diagnosed with concurrent Chronic Myeloid Leukemia (CML) and Renal Cell Carcinoma (RCC). The patient had a history of CML treated with imatinib for 4 years, with loss of complete hematological response for 3 months before being diagnosed with RCC and lung metastases. Due to a T315I mutation in the BCR-ABL1 gene, the treatment regimen included a novel combination of Axitinib, Dasatinib, and low-dose nivolumab. The patient showed a remarkable therapeutic response with a complete metabolic response accompanied by a highly significant reduction in the size of the tumor and complete resolution of the metastatic lung lesions, as well as a major molecular response in terms of CML disease control.
