ASCO's Provisional Clinical Opinion alerts oncologists to emerging information from recent clinical trials that can assist them in treatment selection. Evidence suggests that cetuximab and panitumumab are ineffective in patients with KRAS mutations at codon 12 or 13. Thus, patients with colorectal cancer with these mutations should be spared the toxicity and cost of an ineffective therapy.
ASCO 的临时临床意见提醒肿瘤学家注意最近临床试验中出现的新信息,这些信息可以帮助他们进行治疗选择。有证据表明,西妥昔单抗和帕尼单抗对密码子 12 或 13 发生 KRAS 突变的患者无效。因此,患有这些突变的结直肠癌患者应该避免无效治疗的毒性和费用。
