Improving survival of medulloblastoma: results in two groups of patients.

This retrospective study compares the results obtained in 56 children with medulloblastoma treated with two different protocols at our center between 1975 and 1990. Since 1985 we have been enrolled in the medulloblastoma SIOP II protocol in which we have entered 27 patients. These patients from the SIOP group (SG) and the 29 children treated before 1985, the historical group (HG). When the two groups were compared for age and sex distribution, no differences were found; however, prognostic factors were worse in the HG than in SG: 21 versus 15 T3-T4 and 13 versus 8 high-risk, respectively. The relapse rate was 63% for the HG and 39% for the SG. Five-year disease-free survival was 31% for the HG and 56% for the SG (p = 0.037). Five-year survival was 52 and 70%, respectively (p = 0.055). When SG and HG were compared by stratifying for tumor size, surgical resection and the risk variable, better disease-free survival was obtained in SG than in HG. In a multivariate analysis, the HG and the high-risk proved to be variable independent predictors of poor survival. We observe an increase in survival in our patients with medulloblastoma.

[Total gastrectomy in newborn infant].

Total gastrectomy is rarely indicated in childhood and when necessary it involves multiple ulterior therapeutic problems, mainly nutritional, which need a meticulous physiological approach to avoid further complications, as illustrated by the following patient who, at age 15 months, was submitted to total gastric resection, Y en Roux esophagojejunal anastomosis and splenectomy, because of peritonitis secondary to dehiscence of a recent esophagogastric anastomosis for partial gastric resection due to gastric volvulus and necrosis, which in turn were associated to diaphragmatic relaxation. The patient was admitted to our hospital one month later with signs of acute calorie-protein malnutrition (W/A 60% and W/H 68%, NCHS standards) requiring combined parenteral and enteral nutritional support (via central venous catheter and jejunostomy tube for 15 and 35 days respectively) together with intramuscular vitamin B 12, oral iron and oral vitamin supplements before it became possible to fed him only by mouth. Prophylaxis against Streptococcus pneumonia infections with monthly benzatin penicillin was also instituted. Mean daily weight increases of 16 g, W/A 68% and W/H 74% were thus achieved before hospital discharge, without evidence of dumping syndrome nor alkaline reflux.
