Treatment response based on RECIST or PET.

Response	RECIST	PET
CR/CMR	15 (25.0%)	13 (21.7%)
PR/PMR	37 (41.6%)	31 (51.7%)
SD/SMD	7 (11.7%)	8 (13.3%)
PD/PMD	13 (21.7%)	8 (13.3%)
Total	72 (100%)	60 (100%)

Abbreviations: RECIST: Response Evaluation Criteria in Solid Tumors; PET: positron emission tomography; CR: complete response; CMR: complete metabolic response; PR: partial response; PMR: partial metabolic response; SD: stable disease; SMD: stable metabolic disease; PD: progressive disease; PMD: progressive metabolic disease. The response of PET is based on the criteria of European Organization for Research and Treatment of Cancer (EORTC) recommendations [13].
