Surgery is potentially curative for primary non-metastatic retroperitoneal soft tissue sarcomas (RPS), although patients remain at risk for local recurrence. To reduce this risk, the addition of radiotherapy to radical surgery may be considered. Nevertheless, level I evidence to support radiotherapy is currently lacking. The results from the EORTC-STBSG 62092-22092 studying this question are awaited. This manuscript addresses issues to consider when radiation-oncologists engage in a multidisciplinary treatment approach for RPS patients, including radiotherapy...

RATIONALE: Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma (NHL). The most common extranodal sites of ALCL are skin, subcutaneous tissue, bone, lung, and gastrointestinal organs. This study reports a case of ALCL with multiple extranodal involvement, especially the whole body skeletal muscles, with the aim to share the imaging features of the ALCL including magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT)...

Retroperitoneal sarcomas (RPS) have fascinated and intrigued physicians both past and present. Operative mortality rates were historically very high and complete resection was not possible for the majority of patients until only the last 2 decades. More recently, changes to the surgical approach and clinical decision-making in RPS have improved patient outcomes. With select integration of nonsurgical therapies, continued RPS-specific research, and ongoing collaborative efforts among major referral centers, the future appears promising...

REVIEW
Piotr L Rutkowski, John T Mullen
The focus of this review is on the management of the less common sarcomas occurring in the retroperitoneal space, including solitary fibrous tumor (SFT), malignant peripheral nerve sheath tumor (MPNST), perivascular epithelioid cell tumor (PEComa), and undifferentiated pleomorphic sarcoma (UPS) of the psoas muscle. As for other retroperitoneal sarcomas, surgical resection is the mainstay of curative therapy, and multidisciplinary preoperative assessment, including percutaneous needle biopsy for histologic confirmation, is the basis for personalized management, as the surgical management, and the integration of systemic therapy and radiation therapy is unique to each histologic subtype...

BACKGROUND Leiomyosarcoma is the most common primary malignancy of the inferior vena cava (IVC), and represents approximately 10% of primary retroperitoneal sarcomas. Leiomyosarcoma presents with non-specific symptoms, including abdominal pain or back pain. There is an increased incidence in immunosuppressed individuals. CASE REPORT An unusual presentation of IVC leiomyosarcoma is reported in a 46-year-old female patient infected with human immunodeficiency virus (HIV) who was on highly active antiretroviral therapy (HAART) and who had a normal CD4 count of 934, who presented with back pain...

Malignant peripheral nerve sheath tumor is a rare tumor occurring in 5%-10% of all malignant soft tissues sarcomas and triton tumor arising from neurofibromatosis type 1 (NF-1) is even rarer with associated high rate of mortality. No case of triton tumor has been reported in Nigeria to the best of our knowledge. We seek to report a case of lately detected retroperitoneal triton tumor presenting in a 12-year-old Nigerian child who was brought with bilateral lower limb weaknesses, weight loss, and a right lumbar mass...

BACKGROUND: Recently, some have argued for routine resection of adjacent but uninvolved organs in patients with retroperitoneal sarcoma (RPS) without stipulating the rationale for such organ resection (beyond the need to achieve a macroscopically complete resection) or examining histopathologic organ invasion (HOI). This study reviewed the authors' experience with primary RPS to investigate the rate and rationale for individual organ resection and the rate of HOI. METHODS: Operative and pathology reports for patients with primary RPS who underwent resection at our institution were retrospectively reviewed...

Posterior reversible encephalopathy syndrome (PRES) is a clinical entity characterized by acute neurological symptoms such as severe headache, seizures, and visual disturbance, and by typical reversible lesion on brain magnetic resonance (MR) images. Since PRES is thought to be caused by vascular endothelial injury due to cytotoxic agents or acute systemic hypertension, the number of reports on PRES associated with angiogenesis inhibitors has been increasing. Although five cases that developed PRES due to pazopanib for renal cell carcinoma have already been reported, none of PRES due to pazopanib for soft-tissue sarcoma has been reported thus far...

BACKGROUND: The American Joint Committee on Cancer (AJCC) recently published the 8th edition of the AJCC Cancer Staging Manual. Major changes were made to the staging algorithm for retroperitoneal sarcoma; however, whether these changes improve staging system performance is questionable. METHODS: This retrospective cohort analysis of 3703 adult patients with retroperitoneal sarcoma in the Surveillance, Epidemiology, and End Results (SEER) database compares a novel staging system incorporating histologic subtype of sarcoma with current and prior AJCC soft tissue sarcoma staging systems using multiple statistical techniques...

AIM: The purpose of this study was to evaluate the efficacy of en bloc nephrectomy for perirenal retroperitoneal sarcoma (RPS) with respect to postoperative kidney function and oncological benefits. METHODS: We performed a comparative study of 114 patients undergoing surgery for primary RPS, classifying cases as nephrectomy (NPX, n = 65) versus no nephrectomy (no-NPX, n = 49). The Δ and % change between preoperative and postoperative estimated glomerulus filtration rate (eGFR) were analyzed to compare renal function changes after surgery...

BACKGROUND AND OBJECTIVES: Surgical resection of retroperitoneal sarcomas (RPS) often involves removal of the ipsilateral kidney. We evaluated the long-term post-operative renal function in patients who underwent a nephrectomy as part of their en-bloc resection of RPS. METHODS: Retrospective review of an institutional database identified RPS patients who underwent nephrectomy for curative intent from 1990 to 2014. The primary outcome measured was chronic kidney disease (CKD) calculated by the glomerular filtration rate (GFR)...

BACKGROUND: This study was designed to assess patterns of recurrence and long-term outcomes of patients undergoing surgery for localized retroperitoneal sarcoma (RPS) after neoadjuvant high dose long-infusion ifosfamide (HLI) and radiotherapy (RT). METHODS: Patients received three cycles of HLI (14 g/m(2)). RT was started in combination with II cycle up to a total dose of 50.4 Gy. Surgery was scheduled 4-6 weeks after the end of RT. The primary endpoint was relapse-free survival (RFS) after surgery...

BACKGROUND: Malignant fibrous histiocytoma is a sarcoma of uncertain origin that can be found both in soft tissues and in bones. It is currently called undifferentiated pleomorphic sarcoma not otherwise specified and it represents a final common pathway in several tumors that are subject to the progress of dedifferentiation. Local recurrence of the tumor in the same location where it was originated occurs in 20-30% of the total number of soft tissue sarcomas. It is less frequent in limbs and more likely to recur in retroperitoneal sarcomas and in head and neck...

Dedifferentiated liposarcoma is typically a nonlipogenic high-grade sarcoma that arises from well-differentiated liposarcoma. It most commonly presents as a large mass in the retroperitoneum. Significant involvement of the gastrointestinal tract by dedifferentiated liposarcoma is uncommon. We present a unique case of dedifferentiated liposarcoma radiographically mimicking a primary colon mass with resulting intussusception; stranding of the adjacent adipose tissue was presumed to be a secondary reactive change...

BACKGROUND: Operative resection remains the definitive curative therapy for retroperitoneal sarcoma. Data published recently show a correlation between improved outcomes for complex oncologic operations and treatment at academic centers. For large retroperitoneal sarcomas, operative resection can be complex and require multidisciplinary care. We hypothesized that survival rates vary between type of treating center for patients undergoing resection for retroperitoneal sarcoma. METHODS: Patients with stage I to III nonmetastatic retroperitoneal sarcomas who underwent operative resection were identified from the National Cancer Database during the years 2004-2013...

Histiocytic sarcoma (HS) is a rare hematopoietic neoplasm. We report a patient with HS treated with induction chemotherapy followed by curative surgery. A 50-year-old man was referred to our hospital because of a retroperitoneal tumor. A computed tomography scan revealed a bulky retroperitoneal mass, infiltrating the surrounding organ. An excisional biopsy confirmed the diagnosis of HS. The tumor shrunk after multidrug chemotherapy. However, positron emission tomography showed uptake of fludeoxyglucose in the residual tumor...

OBJECTIVE: Retroperitoneal sarcomas (RPSs) are rare cancers with some variability in clinical and histopathological presentation. In Germany, general treatment strategies of retroperitoneal sarcoma are unknown since centralized registries do not exist. The objective of this survey was to access the medical care of RPS patients in Germany. METHODS: In cooperation with the German Society of General and Visceral surgery, the German Interdisciplinary Sarcoma Study Group and the patient advocacy group Das Lebenshaus we designed an online survey assessing diagnostic and treatment strategies (e...
