ALB and granular cell tumor: In pursuit of an efficient RAM for GCT patients, various factors have been found to significantly correlate with VTE risk, for example, CS [4, 10, 30, 31, 32, 33], retroperitoneal primary [2], age [34], body surface area (BSA) [35], RPLN [1, 2, 3, 5, 31, 33, 36, 37], elevated lactate dehydrogenase (LDH) [1, 10, 35, 36], central venous catheter [1, 5, 10, 32] or access device [2, 38], number of CTH cycles [39], febrile neutropenia [10], absolute neutrophil count (ANC) [37], albumin [37], C‐reactive protein (CRP) [5] or baseline factor VIII concentrations [40].
