Comparison of Response Evaluation Criteria in Solid Tumours and Choi criteria for response evaluation in patients with advanced soft tissue sarcoma treated with trabectedin: A retrospective analysis

Choi assessment may identify patients with false PD who achieved improved efficacy outcomes, suggesting that trabectedin may delay tumour progression even in the case of non-dimensional response. Dual size and tumour density assessment may be more suitable to evaluate responses to trabectedin in sarcoma patients as well as to improve the decision-making strategies for the continuation of trabectedin therapy.
