Intratumoral 2-HG is a potentially useful biomarker in IDH-mutant chondrosarcoma. A. Scatter plots showing intratumoral 2-HG levels in 38 patients, according to IDH mutation. B. Relationship between intratumoral and serum 2-HG levels in IDH-mutant chondrosarcoma. C. Kaplan–Meier overall survival curves of high-grade (grade 2, 3) IDH-mutant chondrosarcoma patients, according to intratumoral 2-HG levels. D. Kaplan–Meier disease-free survival curves of high-grade (grade 2, 3) IDH-mutant chondrosarcoma patients according to intratumoral 2-HG levels. C–D. Cases that were metastatic at initial diagnosis were excluded.
