Comparison of chemosensitivity between primary site and lung metastasis in CD-DST.

5-FU, 5-fluorouracil; SN38, the active metabolite of irinotecan; OHP, the active metabolite of oxaliplatin.There was no significant difference in chemosensitivity when comparing the lung metastasis and the primary tumor.5-氟尿嘧啶（5-FU，5-fluorouracil）、SN38（伊立替康（irinotecan）的活性代谢产物）以及OHP（奥沙利铂（oxaliplatin）的活性代谢产物）。在比较肺转移灶与原发肿瘤的化学敏感性时，未观察到显著差异。
