Prognostic analysis and clinical characteristics of osteosarcoma and Ewing sarcoma of the rib, sternum, and clavicle: a SEER-based study.

ABSTRACT:

Objective

Osteosarcoma and Ewing sarcoma of the rib, sternum, and clavicle are rare tumor entities, and their clinical features and treatment outcomes have been rarely reported. The present study was performed to evaluate their survival and confirm independent survival predictors.

Methods

Data on patients with osteosarcoma or Ewing sarcoma of the rib, sternum, and clavicle from 1973 to 2016 were retrospectively extracted from the database. Univariate and multivariate Cox regression analyses were used to determine the independent risk factors. Kaplan-Meier survival curves were applied to examine the prognostic difference between the groups.

Results

In total, 475 patients with osteosarcoma or Ewing sarcoma of the rib, sternum, and clavicle were eligible for this study,
