Pancreatitis following the administration of L-asparaginase (L-asp) has been well documented. However, the progression of such pancreatitis to pseudocyst formation in some patients has been rarely reported. The few reported cases have been teenagers, with the exception of one adult. All pseudocysts required surgical management. This report documents a pancreatic pseudocyst in a seven-year-old girl with acute lymphoblastic leukemia whose treatment regimen included L-asp. The pseudocyst was managed medically with nasogastric decompression, intravenous hyperalimentation, and antibiotics. The pseudocyst resolved spontaneously in one month without complication.

L-asparaginase is a key component of the antileukemic therapy in children with acute lymphoblastic leukemia (ALL). Pancreatitis has been noted to be a complication in 2-16% of patients undergoing treatment with L-asparaginase for a variety of pediatric neoplasms. Most cases of pancreatitis associated with L-asparaginase toxicity are self-limiting and respond favorably to nasogastric decompression and intravenous hyperalimentation. However, in rare instances, hemorrhagic pancreatitis or necrosis may occur. L-asparaginase-induced pancreatitis is an uncommon but potential lethal complication of the treatment of leukemia. We present a pediatric patient with leukemia and a severe, L-asparaginase-induced necrotizing pancreatitis, treated successfully with percutaneous drainage used to flush the infected necrotic parts.

Chemotherapy protocols for canine lymphoma include the routine use of glucocorticoids for their lympholytic effect. However, glucocorticoids are associated with side effects (e.g. polyphagia, polyuria, and weight gain), limit the use of non-steroidal anti-inflammatory drugs, and can induce drug transporter expression that could lead to drug resistance. Despite these negative effects, there are no data to support the use of glucocorticoids as part of a multidrug chemotherapy protocol for the treatment of canine lymphoma. A prospective, randomized clinical trial was conducted in 81 dogs with multicentric lymphoma and no history of recent glucocorticoid use. All dogs were staged and treated with the same chemotherapy protocol (L-asparaginase, cyclophosphamide, doxorubicin, vincristine, and prednisolone) with half of the dogs receiving prednisolone. Both treatment groups were similar with respect to demographics, immunophenotype, and clinical stage, except for a higher number of substage b patients in the prednisolone group (5 vs. 14; P=0.015). Treatment results obtained with the initial treatment (complete response rate 75%, disease-free period 176 days) and rescue treatment (complete response rate 45%, disease-free period 133 days), overall survival (283 days) and adverse events (number and grade) were similar for both groups. In conclusion, prednisolone, as part of a multidrug chemotherapy protocol, has no additional effect on treatment results and can be omitted from first-line multidrug protocols used for the treatment of canine lymphoma.
