This retrospective study reviewed the clinical data of non-small cell lung cancer (NSCLC) patients who were treated in three different Jordanian hospitals with pembrolizumab-based therapy in first-line setting. The study is well supported with briefly explained figures. The Discussion puts forth the rationale for taking up the study, effectively describes the relevant literature and enlists the implications of the findings from the present study in that context. It showed that a lower fixed dose of pembrolizumab (100mg every 3 weeks) is feasible and has no difference in objective response rate (ORR), progression free survival (PFS), or overall survival (OS) in a Jordanian cohort, with significant cost savings and wider patient accessibility. The Conclusion is apt in recommending a randomized trial for investigating the low dose with significant cost reduction potential.

Further comments on the paper

Comments: This study aims to retrospectively assess the efficacy of pembrolizumab based therapy in the first line setting treatment of advanced non-small cell lung cancer patients from Jordan, and to compare a lower fixed dose (100mg) of pembrolizumab versus a standard fixed dose (200mg). The study holds significance as the lower dose will have significant cost reduction since Jordan is a low-middle income country. This study revealed that the addition of pembrolizumab to first line treatment protocols in advanced non-small cell lung cancer (NSCLC) in this Jordanian cohort of patients is of high clinical importance.


Q: Would you recommend this manuscript for further publication?
