Excerpt
Recently, a series of studies have reported the survival benefit of primary tumor resection for non-small cell lung cancer patients with localized pleural seeding found unexpectedly during surgery (stage 4, s-pM1a).
1 However, for initial treatments after surgery, it remains controversial whether significant differences in survival exist between chemotherapy, targeted therapy, and the wait-and-see strategy. Similarly, it is challenging to select subsequent treatments for patients who have relapsed and experienced pleural dissemination lesions after surgery (stage 4, r-pM1a). In their previous study, the authors proposed that s-pM1a and r-pM1a represent the same disease, with common indolent biologic behaviors, but in different phases.
2 Thus, the authors believed that the wait-and-see strategy might be feasible as an initial treatment for these two special subsets, similar to some special cases of soft tissue sarcoma
3 and lymphoma.
4 Furthermore, the vast differences between attenuated and rapid progression for pM1a patients with the same disease phase raised the question whether these distinct progression patterns were determined by the genetic characteristics of the tumor, which are reported to correlate with tumor progression.
5 Therefore, the current study
6 focused on the survival outcomes for patients with s-pM1a or r-pM1a disease treated with the wait-and-see strategy or conventional postoperative therapies and evaluated the feasibility of the wait-and-see strategy. In addition, this study explored potential molecular markers associated with progression. …
