Surgery for primary retroperitoneal sarcomas (RPS) often requires a technically challenging, en bloc multivisceral resection to optimize outcomes. Surgery may also be appropriate for patients with localized recurrent RPS. Anatomic considerations and tumor biology driven by histologic subtype may guide the extent of resection in patients with RPS. This review provides an overview of the current surgical principles for primary and recurrent RPS.

Resection of retroperitoneal sarcoma (RPS) typically involves multivisceral resection. The morbidity of RPS resection has decreased over time despite widespread adoption of radical resection. Certain patterns of resection are associated with higher complication rates and elderly patients are at increased risk of morbidity. Administration of preoperative radiotherapy does not increase morbidity, but intraoperative and brachytherapy techniques are associated with heightened toxicities. Long-term functional outcomes and quality of life scores after RPS resection are acceptable...

Epithelioid sarcoma (ES), a mesenchymatous malign neoformation, is often diagnosed in later stages and associated with high recurrence index, metastasis and mortality. We report a case of a 65 years old male, with history of abdominal pain and upper gastrointestinal bleeding. Endoscopy demonstrated a posterior duodenal wall perforation communicating with a solid retroperitoneal neoformation. Endoscopic biopsy was performed, with a final report of ES. The patient was submitted for surgical palliation due to the tumor's unresectability...

Categories of noncurative surgery for retroperitoneal sarcoma include: i) grossly incomplete resection (R2) of primary or locally recurrent tumor; ii) resection in the setting of distant metastatic disease; and iii) true palliative-intent symptom-directed surgery. The value of R2 resection is debatable, since most series do not report initial operative intent. Debulking surgery provides symptom relief in the majority of patients, but relief is generally not durable. Quality of life is poorly studied.

PURPOSE: Retroperitoneal sarcomas (RPS) are connective tissue cancers that are often large and anatomically in close proximity to critical and radiation-sensitive normal structures and organs within the abdomen and pelvis. The management of RPS may include preoperative radiotherapy (RT) and surgery. We aimed to examine how treatment-related toxicities affect patient quality of life (QOL).  Methods and materials: Within two prospective cohort studies, 48 RPS patients who were treated with preoperative RT from 1998-2012 were recruited and assessed for QOL (EORTC-QLQ-C30) and to determine toxicities potentially related to RT and surgery (graded using CTCAE V...

Sarcomas represent a highly heterogeneous group of tumors as reflected in the significant overlap between their histologic phenotypes between the different types, posing diagnostic challenges for the pathologist. Definitive tumor classification is increasingly important because of prognostication and emergence of targeted therapies for some of the sarcoma types. In this review, we highlight pertinent pathologic and molecular aspects of sarcomas common in the retroperitoneum, relevant to the surgical oncologist...

BACKGROUND: We investigated whether concomitant organ removal as part of the primary resection of RP WDLPS confers an outcome advantage in patients treated at a major sarcoma center. METHODS: The departmental sarcoma database was reviewed to identify patients with RP WDLPS who underwent initial surgical resection for primary disease at MD Anderson Cancer Center during the study period 1995-2011. We retrospectively reviewed medical records and examined associations between clinicopathologic variables and overall survival (OS) as well as disease-free survival (DFS)...

The differential diagnosis of retroperitoneal mass includes liposarcoma, leiomyosarcoma, malignant fibrous histiocytoma, neurofibroma, stromal tumor, teratoma, and lymphoma. Leiomyosarcoma is rare with poorer prognosis than other soft tissue sarcomas. Soft tissue sarcoma of retroperitoneal origin often remains asymptomatic until tumor enlargement, leading to diagnosis at advanced stages.

Leiomyosarcomas are sarcomas that originate within smooth muscle cells and generally occur in older patients. These tumours account for 10% of all soft-tissue sarcomas. Metastases occur most commonly to the lungs, kidneys, and liver. Cutaneous metastases may also occur but are usually a very rare and late event. We present a case of a 46-year-old woman who developed subcutaneous metastasis to the axilla, arm and breast after surgical resection of the primary tumour. The patient maintained controlled disease with surgical resections and clinical follow-up, initiating chemotherapy one year after the diagnosis of metastatic disease...

A late-relapse germ cell tumor might contain malignant non-germ cell tumors, known as 'somatic-type malignancy (SM)'. The development of a secondary SM is rare, and this phenomenon remains poorly understood. Case 1 developed lung metastasis 13 years after chemotherapy followed by retroperitoneal lymph node dissection for stage IIA non-seminoma. The tumor increased in size after chemotherapy. The patient underwent a pneumonectomy. Pathology revealed an adenocarcinoma with immature teratoma. The patient has experienced no relapse for 9 years...

BACKGROUND: Peri-operative radiation of retroperitoneal sarcomas (RPS) is an important component of multidisciplinary treatment. All retrospective series thus far included patients treated with older radiation therapy (RT) techniques including 2D and 3DRT. Intensity modulated radiation therapy (IMRT) allows for selective dose escalation while sparing adjacent organs. We therefore report the first series of patients with RPS treated solely with IMRT, surgery and chemotherapy. We hypothesized that IMRT would permit safe dose escalation and superior rates of local control (LC) in this high-risk patient population...

Rhabdomyosarcoma (RMS) is a rare soft tissue sarcoma. The already documented data regarding RMS state that it is more prevalent in males than females and also that its occurrence is more in Caucasians than Asians. The current incidence of RMS is 4.5 cases/million, and thus, it is a very rare cancer. The undifferentiated type is the most aggressive one with a rare presentation in the retroperitoneum. Overall, this case emphasizes that consideration should be given to wide range of diagnosis and that frozen section is the gold standard for a confirmatory diagnosis, as the first biopsy showed benign cells within the tumor...

REVIEW
Anastasia Constantinidou, Robin L Jones
There is paucity of randomized controlled data on the role of systemic therapy in retroperitoneal sarcomas. The type of systemic therapy used is guided by the histological subtype. The majority of retroperitoneal sarcomas comprising liposarcomas and leiomyosarcomas are by and large chemotherapy insensitive. There is an urgent need for more efficacious systemic therapies in the management of early and advanced stage retroperitoneal sarcomas.

Retroperitoneal sarcomas (RPS) frequently involve major vessels, which either originate from them or secondarily encase or invade them. In this field, major vascular resections result in increased morbidity. However, survival does not seem to be affected by the need for vascular resection or by this higher morbidity. This paper aims to provide descriptions of the surgical strategy and outcomes for retroperitoneal sarcomas involving major vessels.

Patients with retroperitoneal sarcoma can present to a variety of clinicians with non-specific symptoms and retroperitoneal sarcomas can be incidental findings. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in non-specialist centers. Therefore it is critical that the possibility of retroperitoneal sarcoma should be considered with prompt referral to a soft tissue sarcoma unit. This review guides clinicians through a diagnostic pathway, introduces concepts in response assessment and new imaging developments...

REVIEW
Mohammad Y Zaidi, Robert Canter, Kenneth Cardona
Crafting effective surveillance strategies for retroperitoneal soft tissue sarcomas is difficult given the scarcity of literature on this rare disease. In this article, we will summarize the most recent literature on natural history and recurrence patterns of RPS compiled from multi-institutional collaborative studies and centers with extended follow-up data, and based on this evidence, propose principles for histology-based post-operative surveillance protocols.
