CancerIndex

CancerIndex is a research and information platform. It is not a physician, does not diagnose, and does not recommend treatment. Population statistics do not predict individual outcomes.

Every number links to its source and retrieval date. Derived metrics carry a formula version. AI-generated synthesis is not enabled in this phase; all content is database-grounded.

Definition

What this entity is

A small round cell tumor that lacks morphologic, immunohistochemical, and electron microscopic evidence of neuroectodermal differentiation. It represents one of the two ends of the spectrum called Ewing sarcoma/peripheral neuroectodermal tumor. It affects mostly males under age 20, and it can occur in soft tissue or bone. Pain and the presence of a mass are the most common clinical symptoms.

Key figures

At a glance

Each figure carries its unit, period and source; ranks link to "Why this rank?".

No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
