Genomic determinants of response to cytotoxic chemotherapy. Genomic determinants of response to cytotoxic chemotherapy. A, Swimmer's plot showing months on first-line platinum-based therapy for 187 patients with metastatic, HER2− esophageal cancer. The annotation tracks on the left of the y-axis indicate the patient's best response to platinum and the estimated LST score. The color of individual bars indicates the current status of the patient on this line of treatment. B, Distribution of LST scores in patients who progressed on platinum treatment before 24 months compared with patients with prolonged response (≥24 months). Horizontal bars represent the median by group. CR, complete response; PR, partial response; SD, stable disease. Yelena Y. Janjigian et al.
