Solitary Plasmacytomas: Current Status in 2025

Area of Science:

• Oncology
• Hematology

Background:

• Solitary plasmacytoma is a rare neoplastic proliferation of plasma cells forming a single mass.
• It is classified as either solitary bone plasmacytoma or extramedullary plasmacytoma.
• These rare tumors pose a risk of transforming into multiple myeloma, necessitating optimal management and follow-up.

Purpose of the Study:

• To review key studies and guidelines for the management of solitary plasmacytoma.
• To address the evidence gaps caused by the rarity of these tumors and challenges in clinical trials.

Main Methods:

• Literature review of key studies and clinical guidelines.
• Analysis of the role of newer imaging techniques in staging and decision-making.
• Evaluation of current and emerging treatment modalities, including radiation and chemotherapy.

Main Results:

• Newer imaging techniques have enhanced staging, management, and outcomes.
• Radiation therapy remains a significant component of treatment.
• Adjuvant chemotherapy is increasingly important, with ongoing trials.

Conclusions:

• Optimal management and meticulous follow-up are crucial for solitary plasmacytoma.
• Biochemical tests are essential for response assessment during follow-up.
• Further research and clinical trials are needed to refine best practices.
