Chisholm et al developed a nomogram for evaluating a patient with rhabdomyosarcoma in relapse. This can help to identify a patient who may benefit from salvage therapy. The authors are from Royal Marsden Hospital and multiple hospitals in Europe and South America.
Patient selection: recurrent rhabdomyosarcoma
Parameters:
(1) types of chemotherapy
(2) histology
(3) nodal status
(4) tumor site
(5) tumor size in cm
(6) type of recurrence
(7) history of radiation therapy
(8) time to relapse

total score =
= SUM(points for all 8 parameters)
Interpretation:
• minimum score: 0
• maximum score: 536
• The higher the score the greater the chances of cure after salvage therapy
