A prognostic nomogram to predict clinical outcomes of patients with primary malignant and benign retroperitoneal tumors.

ABSTRACT:

Background

Primary retroperitoneal tumor (PRT) is a relatively rare tumor with diverse histological and molecular types. We aim to develop and validate a concise prognostic nomogram for patients with benign and malignant PRT.

Methods

The clinical data of 206 PRT patients who underwent surgical management in authors' institution during January 2016 and December 2021 were analyzed. Logistic regression was used to select independent risk variables of binary outcome, while COX regression was performed for time-to-event. A predictive nomogram was developed based on multivariate analyses.

Results

Of the reported 206 PRTs, 113 patients were benign (54.85%) and 93 (45.15%) were malignant. Radical resection, extended radical resection and cytoreductive resection were performed
