Soft tissue tumors of the pelvis: Technical and histological considerations

Abstract

In this review, we first address the anatomic and technical considerations in the resection of pelvic soft tissue tumors, including the challenges unique to these tumors, such as the narrow anatomic confines of the bony pelvis, the often locally aggressive nature of these tumors, as well as the major functional deficits that may result from their resection. We then review the optimal, multidisciplinary, histology-driven treatment approach to pelvic tumors.

Surgical Principles of Primary Retroperitoneal Sarcoma in the Era of Personalized Treatment: A Review of the Frontline Extended Surgery

“…Both the rectum and the bladder, as well as nervous structures, should only be resected if there exists tumoral infiltration. Given the high risk of positive microscopic margins at these localizations, the use of preoperative and/or intraoperative radiotherapy (IORT) is recommended [ 50 , 51 , 52 ].…”

Surgical navigation for challenging recurrent or pretreated intra‐abdominal and pelvic soft tissue sarcomas

“…Safety was evaluated based on adverse events caused by the system and the usability using a survey containing the System Usability Scale (SUS). 7 The SUS consists of 10 items that can be answered by the surgeon based on a 5-point Likert scale (1)(2)(3)(4)(5) which are converted to a score ranging 0-100. Higher scores imply higher user-friendliness of the system and a mean SUS score above 70 is considered acceptable and indicates the system has a high chance of acceptance by users.…”

“…However, resection of pretreated tumors with systemic therapy or radiotherapy can sometimes be more challenging due to fibrosis and/or shrinkage of the tumor, while also resections of small recurrent tumors can be more difficult due to anatomical and fibrotic changes after previous surgery. 3 In these situations, localization of the tumor and identification of the tumor outline during surgery can be more challenging, potentially leading to a search for the tumor in a compromised environment and an increased risk of complications.…”

Primary pelvic soft tissue sarcomas (PELVISARC): outcomes from the TransAtlantic Australasian Retroperitoneal Sarcoma Working Group (TARPSWG)

“…A proposed operative definition of adult PSTS includes those arising from non-visceral pelvic structures, delineated anteriorly by the pubis and inguinal ligament, posteriorly by the sacrum, superiorly by the parietal peritoneum and inferiorly by the pelvic floor 5 . This anatomical region exhibits constraints and complex relationships with surrounding organs and structures that potentially can influence disease progression, treatment and prognosis 6 .…”
