GIST, gastrointestinal stromal tumour; LMSC, leiomyosarcoma; NCNNE, non-colorectal, non-neuroendocrine; SC, sarcoma.
*Sarcoma and leiomyosarcoma cases account for a small number of tumours in these studies. GISTs have not been identified separately. The likely amount of GISTs in the series are mentioned in the ‘supposedly GISTs’ section of the table. The survival rates display results for the concerned subgroups.
