Description

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

Interpretation:

• minimum score: 0

• maximum score: 536

• The higher the score the greater the chances of cure after salvage therapy
