What treatment would you recommend for a patient with non-mutated Stage III lung squamous cell carcinoma with relapse following neoadjuvant chemoimmunotherapy, surgery, and during adjuvant immunotherapy?

If relapse is later than 6 mo since chemo discontinued, retreat with the same chemo. If relapse is less than 6 mo, can consider alternative therapy such as doce +/- ram, a clinical trial, or pembro/ramicirumab as in SWOG trial.
