Efficacy of PD-1 inhibitors combined with pegylated liposomal doxorubicin and dacarbazine compared with liposomal doxorubicin and dacarbazine in advanced leiomyosarcoma patients: a retrospective, single-institutional cohort study

ABSTRACT:

Background

PD-1 inhibitor monotherapy is ineffective for metastatic leiomyosarcoma (LMS), but it remains unclear whether PD-1 inhibitors demonstrate any efficacy when combined with chemotherapy. This study retrospectively evaluated pegylated liposomal doxorubicin (PLD) and dacarbazine (DTIC) with/without PD-1 inhibitors for advanced/metastatic LMS patients treated in our single institution.

Methods

The inclusion criteria were a confirmed histological diagnosis of LMS, treatment between January 2020 and March 2022, measurable disease (evaluated by CT or MRI), an Eastern Cooperative Oncology Group (ECOG) performance status ≤2, and age ≥18 years. The endpoints were progression-free survival (PFS), overall survival (OS), and overall response rate (ORR).
