Abstract
Soft tissue sarcoma is a rare form of cancer which accounts for less than 1% of all cancers. Although soft tissue sarcomas can occur anywhere in the body they most commonly originate in the limbs or limb girdle.
The optimal management of soft tissue sarcomas requires a multi-disciplinary team approach that includes input from surgical and medical oncologists, radiologists and pathologists. The high rate of local resection failure is often caused by insufficiently extended primary resections.
The most important prognostic factor is the size of surgical radicality. The operation aims at the removal of the whole tumor bearing anatomic compartment.
Although many studies have considered what constitutes an appropriate margin, no randomized trials or prospective studies have assessed surgical margins and outcomes for soft tissue sarcoma of the extremities. Most of the available evidence comes from retrospective reviews of charts and databases.
Thirty patients with mean age and standard deviation (SD) of 46.73 ± 12.01 years were examined. In each case the surgeon selects a margin called (margin “S”) by gross suspicion to be examined intra-operatively by frozen section, but after that, the pathologist examines all other margins of the tumor by intra-operative frozen section. The aim was to decrease the operation time and complications and to know if the surgeon is able to identify the positive margin by gross suspicion.
