下面这是今年4月 吴一龙参与发表的一篇文章,非常有意思.
对比结果: PFS 化疗优于靶向, OS 无显著差异!
这说明什么? 其实这说明2个问题
1。吴一龙之前说了: EGFR 野生靶向就是无效= 靶向等于安慰剂
2。化疗 ,历史告诉我们化疗对总生存时间没有帮助。
好了,这篇的结论就是告诉我们, 野生型, 靶向or 化疗= 回家睡觉 。
个人对化疗采取非常保守态度!

Efficacy of epidermal growth factor receptor inhibitors versus chemotherapy as second-line treatment in advanced non-small-cell lung cancer with wild-type EGFR: A meta-analysis of randomized controlled clinical trials
Abstract
Background
EGFR mutation status is closely related to the efficacy of EGFR-TKIs in advanced non-small cell lung cancer (NSCLC). EGFR-TKIs have become the standard first-line treatment for advanced EGFR-mutation NSCLC, while for EGFR wild-type tumors, the preferred first-line treatment is chemotherapy. However, the efficacy of EGFR-TKIs as second-line treatment in EGFR wild-type NSCLC remains controversial. We sought to evaluate the effectiveness of EGFR-TKI as second-line treatment in EGFR wild-type NSCLC.
Methods
Randomized controlled trials that compared EGFR-TKIs with chemotherapy in previously treated advanced NSCLC with wild-type EGFR were included. We performed a meta-analysis to evaluate the effectiveness of EGFR-TKIs compared with standard chemotherapy. The endpoints were progression-free survival (PFS), overall survival (OS), and objective response rate (ORR).
Results
Six randomized controlled trials with a total of 990 patients with wild-type EGFR were included: 499 in the EGFR-TKIs group and 491 in the chemotherapy group. The results indicated that in the second-line treatment of EGFR wild-type advanced NSCLC, PFS was significantly inferior in the EGFR-TKIs group versus the chemotherapy group (HR = 1.37, 95% CI = 1.20–1.56, P < 0.00001). However, this significant difference did not translate into OS (HR = 1.02, 95% CI = 0.87–1.20, P = 0.81). ORR tended to favor chemotherapy but there was no significant difference compared with EGFR-TKI (RR = 1.77, 95% CI = 0.90–3.50, P = 0.10).
Conclusions
Chemotherapy improves PFS significantly but not OS, compared with EGFR-TKIs as a second-line treatment in advanced NSCLC with wild-type EGFR. Whether EGFR-TKIs should be used in EGFR wild-type patients should be considered carefully. |
