Preoperative lymphocyte count in relation to sarcoma prognosis

Area of Science:

• Oncology
• Immunology
• Surgical Pathology

Background:

• Inflammation is a key factor in cancer development and metastasis.
• Several blood cell count ratios, including neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR), are emerging as prognostic indicators in various cancers.

Purpose of the Study:

• To evaluate the association between preoperative blood cell count ratios and the survival prognosis of sarcoma patients undergoing surgery.
• To determine if NLR and LMR can serve as predictive markers for sarcoma patient outcomes.

Main Methods:

• Retrospective analysis of 142 sarcoma patients from an Orthopaedics Oncology Database.
• Kaplan-Meier survival analysis and multivariate Cox proportional hazard models were employed.
• Assessment of preoperative absolute lymphocyte count, NLR, and LMR in relation to overall survival.

Main Results:

• A high preoperative lymphocyte-monocyte ratio (LMR) was significantly linked to improved overall survival and prognosis in sarcoma patients.
• Conversely, a high preoperative neutrophil-lymphocyte ratio (NLR) was significantly associated with shorter overall survival and poorer prognosis.
• Multivariate analysis confirmed NLR and LMR as valuable predictors of 3- and 5-year overall survival, respectively.

Conclusions:

• Preoperative NLR and LMR are effective and cost-efficient prognostic markers for predicting clinical outcomes in sarcoma patients.
• These markers can identify patients at high risk for poor outcomes, enabling timely and aggressive treatment strategies.
• Routine peripheral blood counts can be utilized as accessible tools for sarcoma prognosis.
