RESUMEN
This article describes the case of a 73-year-old patient with grade 3 immune checkpoint inhibitor (ICI)-induced enteritis. Five different immunosuppressive agents (glucocorticoids, high-dose infliximab, methotrexate, mycophenolate mofetil, and vedolizumab) were administered, however, with no clinical or radiographical benefit. A laparotomy was performed, as the patient showed signs of intestinal obstruction, with a segmental resection of the ileal loop. Biopsy results showed multiple fibrotic strictures. The current treatment guidelines for ICI enterocolitis only include drugs as a treatment option. Nevertheless, it remains important to consider early surgical intervention in order to avoid serious complications due to persistent and pronounced inflammation. The current case highlights the importance of surgery as a treatment modality in the multidisciplinary approach for ICI-induced enteritis, which should be taken into consideration after second- or third-line treatment.
RESUMEN
Hepatocellular carcinoma is the fourth leading cause of cancer-related death worldwide, with limited treatment options for patients with advanced hepatocellular carcinoma. Beyond standard systemic therapy with multikinase inhibitors, recent studies demonstrate the potential for a robust and durable response with immune checkpoint inhibition in subsets of patients with hepatocellular carcinoma.We present a case of an 83-year-old male patient with the diagnosis of a multifocal hepatocellular carcinoma. A hepatoduodenal fistula developed under treatment with sorafenib which necessitated treatment interruption. Therefore, a switch to second line therapy with immunotherapy nivolumab was made and supportive enteral nutrition was started. This led to a spectacular oncological response, with complete resolution of the hepatoduodenal fistula. To our knowledge this is the first case which describes the involution of a fistula in a hepatocellular carcinoma under treatment with nivolumab.
