Risky Remedy: Rasburicase-Induced Methemoglobinemia in Tumor Lysis Syndrome Complicated by G6PD Deficiency.

Tumor lysis syndrome (TLS) is a critical oncologic emergency characterized by metabolic disturbances resulting from rapid cancer cell lysis. Rasburicase, a recombinant urate oxidase, is the primary treatment for hyperuricemia in TLS but poses a risk for methemoglobinemia in patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency. We present the case of a 59-year-old male with diffuse large B-cell lymphoma (DLBCL) who developed spontaneous TLS.

Burkitt lymphoma: interpreting FISH testing for gene rearrangements.

Burkitt lymphoma is a highly aggressive B cell non-Hodgkin's lymphoma characterised by translocation of gene on chromosome 8. This translocation is usually detected by fluorescent in-situ hybridisation (FISH) studies as part of routine diagnostic work-up and prognostication. FISH testing is commonly done with the break-apart probe (BAP).

Third Line Eribulin for Triple-negative Metastatic Breast Ductal Carcinoma Resulting in Extended Progression-free Survival of 57 Months.

Eribulin is a non-taxane microtubule inhibitor approved for the treatment of metastatic breast carcinoma after two prior chemotherapeutic regimens. We report a patient with extended progression-free survival (PFS) of more than 57 months with metastatic breast carcinoma treated with eribulin in the third-line setting. A 48-year-old lady was diagnosed with stage IIA (pT2N0M0), high grade, triple-negative, invasive ductal carcinoma (IDC) of the left breast on core needle biopsy.

Long-time Response with Ado-trastuzumab Emtansine in a Recurrent Metastatic Breast Cancer.

Breast cancer is the most common cancer in a woman with a five-year survival of patients with metastatic disease is estimated at 23%. Ado-trastuzumab emtansine (T-DM1) is a HER2-antibody drug conjugate currently approved for the treatment of HER2-positive pre-treated metastatic breast cancer (BC). We report a case of recurrent metastatic breast cancer with unusually lengthy progression-free survival (PFS) on T-DM1 chemotherapy.
