The objective of this study is to provide a review of the large number of drugs and their efficacy as of 2022, for lung cancer, but also introduce a novel treatment that has the potential, based on one controlled murine lung cancer study and 5 anecdotal human cases, that showed marked palliative and longevity benefits in very advanced lung cancer with no other treatment options, i.e., progesterone receptor (PR) antagonists targeting the immunosuppressive protein, the progesterone induced blocking factor (PIBF). Credibility, however, will only be provided when the efficacy can be demonstrated in a large series of lung cancer cases ideally with certain controls. Thus, the ultimate objective of the review is to interest oncologists with a large population of lung cancer patients to perform a well powered study to corroborate or refute the limited experience to date with PR antagonist therapy. %U https://ar.iiarjournals.org/content/anticanres/43/3/951.full.pdf
