Published date:
01/12/2021
Excerpt:
EGFR-mutant NSCLC (in-frame deletion in exon 19 or Leu858Arg point mutation in exon 21) were randomly assigned, in a 1:1 ratio, to receive either adjuvant icotinib (125 mg thrice daily administered orally for 2 years) or four-cycle chemotherapy (cisplatin plus vinorelbine, or cisplatin plus pemetrexed...In full analysis population, the median DFS (mDFS) was 47.0 months (95% CI, 36.44 to not reached) in the icotinib group and 22.1 months (95% CI, 16.8 to 30.4) in the chemotherapy group (stratified hazard ratio=0.36; 95% CI, 0.24 to 0.55; P < 0.0001).

Efficacy and Failure Patterns of Early SBRT to the Primary Tumor in Advanced EGFR-Mutation-Positive Lung Cancer with EFGR-TKI Treatment: A Prospective, Single Arm, Phase II Study
Published date:
11/22/2022
Excerpt:
All patients were administered a first-generation EGFR-TKI (icotinib 125 mg tid or gefitinib 250 mg qd, orally)....The PFS of subgroups in number of metastases >5 vs. <5 and EGFR mutation L858R vs. 19-del were 11.13 months vs. 16.33 months (HR 0.45, 95% CI (0.23–0.91), p = 0.016) and 13.43 months vs. 26.69 months (HR 0.23, 95% CI (0.12–0.46), p = 0.0017), respectively (Figure 3)....early-phase SBRT for the primary lung tumor combined with EGFR-TKI followed by RT may be an alternative choice for advanced NSCLC harboring the EGFR mutation.

Title:
Primary lesion radiotherapy during first-line icotinib treatment in EGFR-mutated NSCLC patients with multiple metastases and no brain metastases: a single-center retrospective study
Published date:
07/12/2022
Excerpt:
EGFR-mutant NSCLC patients diagnosed with limited multiple metastases were treated with first-line icotinib….Subgroup analysis showed that the results were statistically significant with 14.7 and 11.5 months for the 19del mutation (HR 0.20, 95% CI 0.10–0.40, P < 0.001) and 12.9 and 9.9 months for the L858R mutation (HR 0.25, 95% CI 0.13–0.48, P < 0.001)....This study suggests that CPRT is a viable option for patients with EGFR-sensitive mutations in NSCLC with limited multiple metastases during first-line icotinib treatment, which can significantly improve PFS with acceptable toxicities.
