In the univariate analysis for OS, several factors emerged as statistically significant prognostic markers, including leiomyosarcoma, sarcoma NOS, total lymphocyte count at baseline, albumin concentration at baseline, RDW at the end of treatment, objective response to gemcitabine–dacarbazine, L-sarcomas (encompassing leiomyosarcoma and liposarcoma), and PLR before treatment initiation. Here, ALB is linked to sarcoma.
