Cardiac toxicity is a widely reported complication of fluoropyrimidine chemotherapies (5-fluorouracil and capecitabine); however, Takotsubo syndrome (TS) is less widely reported. There is little data available describing the viability of fluoropyrimidine rechallenge after fluoropyrimidine-induced TS. We report the case of Ms X, a 41-year-old woman with metastatic oesophageal cancer, who developed acute onset left ventricular dysfunction, with a measured left ventricular ejection fraction of 15% on cycle 1 day 3 of FOLFOX chemotherapy, after disconnection of the fluorouracil infusion pump. Her symptoms resolved over 2 days, and an echocardiogram returned to normal within 2 weeks. 5-Fluorouracil was discontinued, and replaced with capecitabine, without recurrence of symptoms. The remainder of her treatment was uneventful. This is the second case to describe successful capecitabine retreatment following 5-fluorouracil-induced TS.

Case report: A successful case of targeted immunotherapy for locally advanced pancreatic cancer under non-surgical conditions.
Front Immunol
January 2025
Department of Hepatobiliary Surgery, The Second Hospital of Hebei Medical University, Shijiazhuang, Hebei, China.
Introduction: Locally advanced pancreatic cancer (LAPC) is a borderline unresectable malignancy that presents significant treatment challenges. The management of LAPC remains a complex issue, particularly in patients who are not eligible for surgical resection.
Case: Here, we report the case of a 60-year-old woman diagnosed with LAPC through pathological biopsy who subsequently underwent targeted immunotherapy following the failure of a gemcitabine, oxaliplatin, and S-1 (G&S) chemotherapy regimen.
Unusual outcome of treatment of thymoma with immunotherapy: case report.

Background: Thymoma is a rare mediastinal neoplasm originating from thymic epithelial cells, often associated with paraneoplastic syndromes. These syndromes can manifest as a range of autoimmune disorders, including myasthenia gravis, pure red cell aplasia, and aplastic anemia. Clinical trials involving the use of immune checkpoint inhibitors (ICIs) in thymoma have been complicated by a high incidence of immune-related adverse effects (irAEs).

Hypercalcemia is most commonly associated with primary hyperparathyroidism or malignancy in the setting of elevated parathyroid hormone-related protein or bone metastases. Calcitriol (1,25-dihydroxyvitamin D)-mediated hypercalcemia is rare and typically associated with granulomatous conditions; however, other solid-organ etiologies have been reported. Here, we detail the case of a 62-year-old man with metastatic pancreatic neuroendocrine tumor (pNET) with hypercalcemia refractory to traditional bisphosphonate therapy in the setting of vastly elevated 1,25-dihydroxyvitamin D.

Article Synopsis
- The study investigates the interactions between the chemotherapy drug capecitabine (CAP) and gut microbiota in colorectal cancer patients, focusing on how these interactions may affect treatment side effects.
- Research involved a cohort of 56 patients, analyzing stool samples and using advanced sequencing techniques to observe changes in gut microbial composition during CAP treatment.
- Findings indicate that CAP alters gut bacteria, promoting genes related to vitamin K2 production, which appears to protect against drug toxicity, suggesting potential for microbiome profiling to predict chemotherapy side effects.
Challenges in treating coexisting scrotal apocrine carcinoma and gastric cancer: insights from an elderly patient: a case report and literature review.
BMC Geriatr
October 2024
Department of Medical Oncology, Southern University of Science and Technology Hospital, Shenzhen, China.
Background: Apocrine carcinoma associated with Paget's disease is a rare malignancy that typically manifests in elderly individuals, predominantly affecting the geriatric population. It commonly arises in regions rich in apocrine glands and often exhibits an insidious onset, potentially requiring several years to be diagnosed.
Case Presentation: An 80-year-old male was simultaneously diagnosed with scrotal apocrine carcinoma (showing Paget changes) and early-stage gastric cancer.
