Cancer cachexia is defined as a state of involuntary weight loss, attributed to altered body composition with muscle mass loss and/or loss of adiposity. Identifying the association between cancer cachexia and outcomes may pave the way for novel agents that target the cancer cachexia process. Clinical parameters for measurement of cancer cachexia are needed. We conducted a single-institution retrospective analysis that included 86 NHL patients with the aim of identifying an association between cancer cachexia and outcomes in aggressive lymphomas using the cachexia index (CXI) suggested by Jafri et al. (Clin Med Insights Oncol 9:87-93, 15). Impact of cachexia factors on progression-free survival (PFS) and overall survival (OS) were assessed using log-rank test and Cox proportional hazards regression. Patients were dichotomized around the median CXI into "non-cachectic" (CXI ≥49.8, n = 41) and "cachectic" (CXI<49.8, n = 40) groups. Cachectic patients had significantly worse PFS (HR 2.18, p = 0.044) and OS (HR = 4.05, p = 0.004) than non-cachectic patients. Cachexia as defined by the CXI is prognostic in aggressive lymphomas and implies that novel therapeutic strategies directed at reversing cachexia may improve survival in this population.

Spontaneous tumor lysis syndrome (STLS), in the absence of prior chemo or radiation therapy, is rare with solid tumors. Here, we present a case of STLS secondary to a small-cell neuroendocrine tumor of unknown origin in a 66-year-old female patient who presented with abdominal discomfort. Computed tomography (CT) abdomen showed a large tumor mass with peritoneal metastasis, and she developed renal failure from STLS, resulting in the need for hemodialysis. Due to the progressive deterioration and the comorbidities, she opted for comfort care. Timely recognition and intervention of STLS is critical. Further studies evaluating STLS in solid tumor patients are recommended.

Immune checkpoint inhibitors (ICPIs) are a breakthrough therapy in oncology and have been approved by the Food and Drug Administration for the treatment of several malignancies. ICPIs have been reported to cause immune-mediated damage of islet cells leading to ICPI-induced type 1 diabetes mellitus (T1DM). These reports described patients presenting with severe diabetic ketoacidosis (DKA). We present a case of a 69-year-old Caucasian male with type 2 diabetes suffering from non-small cell lung cancer and undergoing treatment with pembrolizumab, an anti-programmed cell death protein-1 antibody, who presented to our emergency department with complaints of nausea, vomiting, polyuria, and polydipsia. He was found to have high anion gap metabolic acidosis with ketosis and elevated blood glucose levels consistent with DKA. Lab workup was consistent with T1DM. Despite being on a tailored insulin regimen, his blood glucose remained elevated, necessitating the addition of metformin to his regimen which effectively controlled his blood glucose.

Abstract. Breast implant-associated (BIA) anaplastic large-cell lymphoma (ALCL) is a rare disease, comprising a small percentage of all non-Hodgkin lymphomas (NHLs), reportedly 2-3%. There is currently no established standard approach to the treatment of BIA ALCL. The first case on the development of ALCL in the presence of a breast implant was reported in 1997 and the association was first identified by the Food and Drug Administration in 2011. We herein describe a case of BIA ALCL in a patient with a previous history of breast cancer and breast reconstruction who presented with hardening of her breast implant. The patient underwent capsulectomy and the findings of the pathological examination were consistent with ALCL. The patient completed three cycles of combination chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP regimen) followed by radiation consolidation therapy, and has maintained a complete remission ever since. The aim of the present study was to review the treatment options for BIA ALCL and suggest an investigation of the CD30-directed antibody-drug conjugate, brentuximab vedotin, as a potential treatment option for BIA ALCL.

Bevacizumab (BV) is a humanized monoclonal antibody that inhibits angiogenesis by targeting vascular endothelial growth factor (VEGF). The addition of BV to combination chemotherapy has been shown to improve the outcomes in several malignancies, including colorectal carcinoma (CRC). However, the use of BV has been associated with adverse effects, including hypertension, hemorrhage, proteinuria, delayed wound healing and bowel perforation. Pneumothorax (PTX) as an adverse event associated with BV use has rarely been reported. We herein report the case of a 68-year-old female patient with a history of metastatic CRC treated with combination chemotherapy, including BV, who presented with complaints of shortness of breath and was found to have a right-sided PTX.
