Clinical characteristics and prognostic factors of patients with solitary plasmacytoma: a multicenter retrospective study.

ABSTRACT:

Background

Solitary plasmacytoma (SP) is a rare plasmacytoma. Research on clinical characteristics and prognostic factors for SP is very limited.

Objective

This study aimed to evaluate the clinical attributes and prognostic indicators for individuals afflicted with SP.

Design

We retrospectively analyzed the clinical parameters and survival data of 49 patients diagnosed with SP from three centers between the year 2009 and 2024.

Methods

The Kaplan-Meier curves were constructed to compare the survival outcomes. The independent risk factors were determined based on the Cox proportional hazards model.

Results

Among the 49 patients with SP, 30 (61.2%) were classified as solitary bone plasmacytoma (SBP), while 19 (38.8%) had solitary extramedullary plasmacytoma
