Rash and subcutaneous fat necrosis after DEB-TACE with doxorubicin.

A 73-year-old woman with hepatocellular carcinoma localised to the liver was treated with doxorubicin-loaded drug-eluting beads through transcatheter arterial chemoembolisation (DEB-TACE). She developed subcutaneous, erythematous, tender nodules in her abdomen 3 days after the procedure. PET/CT scan that was done to evaluate for evidence of disease progression showed mild avidity of these nodules. Biopsy showed fatty necrosis. Nodules started to improve spontaneously 2 weeks after onset. At 8 weeks after onset, lesions stabilised in size and the associated tenderness and erythema resolved. This represents a rare side effect of TACE procedure in general. It can happen secondary to non-target embolisation of hepatic falciform artery, planned embolisation of extrahepatic collateral supplies and even when there is no clear cause. Spontaneous resolution of acute symptoms usually occurs over the course of few weeks, though subcutaneous lesions consisting of necrotic fat tissue may persist for longer periods.

Treatment-Free Remission: a New Therapeutic Goal in Chronic Myelogenous Leukemia.

PURPOSE OF REVIEW: Chronic myelogenous leukemia (CML) is a chronic myeloproliferative neoplasm characterized by the presence of Philadelphia chromosome [t(9:22)] leading to the presence of pathognomonic fusion gene product, BCR-ABL1. This leads to constitutive activation of ABL1 kinase. CML was a difficult-to-treat illness until the advent of small molecule tyrosine kinase inhibitor (TKI), imatinib which revolutionized therapy of CML. Since then, multiple second- and third-generation TKIs have been formulated which have proven effective and has led to marked improvement in survival. In this article, we review currently available data on possibility of holding TKI therapy in patients in deep remission [treatment-free remission (TFR)] and safety of this approach. RECENT FINDINGS: As CML treatment has become more effective, new questions have emerged, most important being whether the treatment with TKIs can ever be stopped. This is especially relevant in patient experiencing side effects from therapy or who may be subject to increased health risks due to treatment. There is now evidence that some CML patients who have achieved stable deep molecular response can safely stop TKI. Furthermore, patients can safely re-establish remission after restarting their TKI therapy in the situation of relapse. CML is highly treatable disease, but the treatment has untoward physical and socioeconomic consequences. The idea of TFR is hence attractive. There is a growing body of evidence that some CML patients who have achieved stable deep molecular response can safely stop TKI.

Ischemic Colitis Associated with Paclitaxel and Carboplatin Combination.

A 62-year-old white female with a history of early-stage triple-negative breast cancer on a combination of carboplatin and paclitaxel in the adjuvant setting presented with lower gastrointestinal bleeding. She tolerated 4 cycles of dose-dense adriamycin/cyclophosphamide with no major symptoms. After 6 cycles of weekly paclitaxel in combination with carboplatin every 3 weeks, she presented with diarrhea and lower gastrointestinal bleeding. Colonosopic examination showed erythema and inflammation in the splenic flexure, descending colon, and sigmoid colon consistent with ischemic colitis. Pathology favored the same diagnosis. She was treated conservatively with intravenous fluids and bowel rest. Chemotherapy was held for 2 weeks and resumed after recovery without carboplatin. She was able to tolerate the remaining 6 cycles of paclitaxel with no recurrence of her symptoms.
