Desmoid Tumor of the Abdominal Wall — What Is the Treatment Approach?

This protocol covers the initial management of desmoid tumor arising specifically at the abdominal wall — a site where anatomical location and disease behaviour are central to treatment decisions.

Clinical scenario

Desmoid tumor of the abdominal wall. Superficial locations such as the abdominal wall carry particular significance in treatment planning: they represent among the best candidates for surgical consideration in cases of continuous progression, yet the same patients may also be suitable for a careful period of observation first.

Initial approach (partial overview)

Current evidence supports proposing a period of active surveillance — regular clinical assessment and imaging follow-up — as the initial strategy before committing to active treatment. The full protocol defines the monitoring framework, the decision criteria for escalation, and the steps that follow.

Clinical goals

The primary aim during the surveillance period is to confirm tumor stability: stable size on imaging and the absence of growth across consecutive scheduled follow-up assessments.

Superficial sites of disease represent the best indications for surgery in cases of continuous progression, particularly in abdominal wall DT.

However, a period of active surveillance should be proposed as the initial strategy for all patients with DT, before making any decision in favor of active treatment.

Persistent tumor growth was ascertained by observing tumor size increase at multiple (>2) consecutive follow-up appointments, threatening quality of life (QOL), life, or function or posing a potential risk to the feasibility or effectiveness of first-line treatment.
