Abstract

Managing a child with acute lymphoblastic leukemia (ALL) after relapse is arduous in low- and middle-income countries. A file review of children aged ≤15 years diagnosed with relapsed ALL from 2010 to 2019 was performed. Classification of relapse followed the Berlin-Frankfurt-Münster (BFM) scheme. The majority of patients were treated with a modified ALL-REZ-BFM protocol. Of 764 children treated for ALL in the study period, 163 (21.3%) relapsed. The median age at relapse was 101 months (range: 8–297). The immunophenotype was B-ALL and T-ALL in 140 (86%) and 23 (14%) patients. The site of relapse was extramedullary, combined, and medullary in 46 (28%), 45 (28%), and 72 (44%) patients. Very early, early, and late relapses were observed in 57 (35%), 66 (40%), and 40 (25%) patients. The proportions of extramedullary and medullary sites were greater among patients with early and late relapses, respectively (p = 0.039). Eighty-four (52%) patients were treated with palliative intent. The 2-year event-free survival (EFS) of patients treated with curative intent was 36.3 ± 6.3%. The 2-year EFS for very early/early and late relapses were 18.2 ± 6.2% and 67.6 ± 10.4% (p < 0.001). The 2-year EFS did not differ between extramedullary, combined, and medullary relapses. Treatment-related mortality occurred in 14 (20%) patients. More than 50% of the patients with relapse were treated with the intent of palliation. Extramedullary relapses were more likely to be early and did not have a better outcome than medullary relapses. Children with late relapse had a fair chance of survival with chemotherapy.

*LIVER metastasis, *DISEASES in teenagers, *GERM cell tumors, *CANCER chemotherapy, *HEPATECTOMY, *LYMPH nodes
Abstract

Systemic dissemination of intracranial germ cell tumors (GCTs) occur only in 3% of cases and the common sites are bone, lungs, and lymph nodes. Metastasis to the liver is rare. As far as we could find, only six cases of liver metastasis of intracranial GCTs have been reported so far. We report an adolescent girl who presented with hepatic relapse 2½ years after successful completion of treatment of intracranial GCT. She was treated with chemotherapy and right hepatectomy and is doing well 30 months after treatment for the metastatic disease. [ABSTRACT FROM AUTHOR]
