Intra-abdominal manifestations are rare and prove particularly difficult to treat when peritoneal sarcomatosis is present. Because of the overall poor prognosis of the disease, a tailored approach to surgical management is essential to achieve satisfactory outcomes with limited morbidity. We present the perioperative and long-term outcomes of 19 cases of sarcoma with peritoneal sarcomatosis treated surgically at our hospital. Treatment pathways were reviewed and clinical follow-up was performed. Patient characteristics, medical history, tumor subtype, surgical approach, hospital stay, complications, follow-up, and overall survival (OS) were assessed. Our patients were 9 women and 10 men with a median age of 45.9 years (18\u201388) and a median survival of 30 months (0\u2013200). In most cases, peritoneal sarcomatosis was either discovered during surgery or the procedure was performed with palliative intent from the beginning. The surgical approach in these cases is very heterogeneous and should consider a variety of factors to tailor an approach for each patient. Sharing our experiences will help to increase knowledge about this rare disease and provide insight into the management of future cases.<\/jats:p>","DOI":"10.3390\/cancers15041340","type":"journal-article","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T05:57:52Z","timestamp":1676872672000},"page":"1340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Treatment Pathways and Prognosis in Advanced Sarcoma with Peritoneal Sarcomatosis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0128-8902","authenticated-orcid":false,"given":"Fabian","family":"Klingler","sequence":"first","affiliation":[{"name":"Department of Surgery (A), Heinrich-Heine-University and University Hospital Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0434-0873","authenticated-orcid":false,"given":"Hany","family":"Ashmawy","sequence":"additional","affiliation":[{"name":"Department of Surgery (A), Heinrich-Heine-University and University Hospital Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8793-568X","authenticated-orcid":false,"given":"Lena","family":"H\u00e4berle","sequence":"additional","affiliation":[{"name":"Institute of Pathology, Heinrich-Heine-University and University Hospital Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0554-2402","authenticated-orcid":false,"given":"Irene","family":"Esposito","sequence":"additional","affiliation":[{"name":"Institute of Pathology, Heinrich-Heine-University and University Hospital Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7476-292X","authenticated-orcid":false,"given":"Lars","family":"Schimm\u00f6ller","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, Medical Faculty, University Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfram Trudo","family":"Knoefel","sequence":"additional","affiliation":[{"name":"Department of Surgery (A), Heinrich-Heine-University and University Hospital Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2496-1079","authenticated-orcid":false,"given":"Andreas","family":"Krieg","sequence":"additional","affiliation":[{"name":"Department of Surgery (A), Heinrich-Heine-University and University Hospital Duesseldorf, D-40225 Duesseldorf, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ressing, M., Wardelmann, E., Hohenberger, P., Jakob, J., Kasper, B., Emrich, K., Eberle, A., Blettner, M., and Zeissig, S.R.
