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...

PURPOSE: The aim of this study was to evaluate the role of preoperative and postoperative external beam radiation therapy (EBRT) in the treatment of resectable soft tissue sarcomas (STSs) of different tumor locations. METHODS: A systematic literature search was performed to identify studies investigating the effects of EBRT (versus no EBRT) on local recurrence (LR) and overall survival (OS) or comparing different EBRT sequences. Random effects meta-analyses were calculated and presented as cumulative odds ratios (ORs)...

Infantile fibrosarcomas (IFS) represent a distinct group of soft tissue tumors occurring in patients under 2 years of age and most commonly involving the extremities. Most IFS show recurrent ETV6-NTRK3 gene fusions, sensitivity to chemotherapy, and an overall favorable clinical outcome. However, outside these well-defined pathologic features, no studies have investigated IFS lacking ETV6-NTRK3 fusions, or tumors with the morphology resembling IFS in older children. This study was triggered by the identification of a novel SEPT7-BRAF fusion in an unclassified retroperitoneal spindle cell sarcoma in a 16-year-old female by targeted RNA sequencing...

INTRODUCTION: In selected cases, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an established treatment for patients suffering from peritoneal metastases from colorectal, ovarian, gastric or appendiceal origin. The effectiveness of this extensive has not been elucidated within other rare diseases by now. METHODS: We conducted a retrospective analysis of patients treated with CRS for peritoneal carcinomatosis during the period between July 2010 and September 2015...

Soft tissue sarcoma is an umbrella term which encompasses over 60 histological tumour types. Approximately 15% of soft tissue sarcomas arise in the retroperitoneum. This complex group of tumours poses unique management challenges due to their often large size, histological heterogeneity and complexity of anatomical relationships. This review discusses the management of retroperitoneal tumours including the need for preoperative diagnosis, the evidence for neoadjuvant radiotherapy, the role of multivisceral resection and the importance of a multidisciplinary team approach...

Small round cell sarcomas are aggressive bone and soft tissue tumors that predominantly affect children and young adults. A new group of sarcomas with a recurrent BCOR-CCNB3 gene fusion has been recently identified in previously unclassifiable small round cell sarcomas. BCOR-CCNB3 sarcomas share clinical and pathologic similarities with Ewing sarcoma, but show a stronger male predilection and less aggressiveness, as well as distinct gene expression profiling and pangenomic SNP array analyses. We report the unusual case of a congenital BCOR-CCNB3 retroperitoneal sarcoma in a female born at 34th gestational week, which was diagnosed in necropsy after 21hours of life...

BACKGROUND: Retroperitoneal tumours often require a preoperative core needle biopsy to establish a histological diagnosis. Literature is scarce regarding the risk of biopsies in retroperitoneal sarcomas, so the aim of this study is to identify the potential risks of core needle biopsies causing needle tract recurrences or local recurrences. METHOD: Patients who underwent resection of a primary retroperitoneal sarcoma between 1990 and 2014 were identified from a prospectively maintained database from two tertiary referral centres...

PAX8 is used as a diagnostic aid in classifying retroperitoneal (RP) spindle cell tumors. PAX8 positivity in a spindled RP tumor is typically associated with sarcomatoid renal cell carcinoma (SRCC). However, PAX8 expression in solitary fibrous tumor (SFT), a tumor not uncommon to the RP, has not been extensively studied. We investigated the expression of PAX8 in SFTs and other spindle cell RP tumors. We collected 30 SFT, 23 SRCC, 11 gastrointestinal stromal tumors, 2 synovial sarcomas, 6 dedifferentiated liposarcomas (DDLS), 4 well differentiated liposarcomas (WDLS), and select other tumors...

INTRODUCTION: The role and timing of postoperative radiotherapy (PORT) in the management of retroperitoneal sarcoma (RPS) remains controversial. METHOD: This is a retrospective cohort review of patients undergoing curative resection for RPS at a single institution between January 2011 and July 2016. Patient selection was through the South Australian Soft Tissue Tumour Multidisciplinary Group (MDT) based at Royal Adelaide Hospital. An individualised approach, including assessment of resectability, histopathological grade and subtype, and radiotherapy considerations, was taken for each patient...

REVIEW

Intraoperative radiotherapy (IORT) is a technique that involves precise delivery of a large dose of ionising radiation to the tumour or tumour bed during surgery. Direct visualisation of the tumour bed and ability to space out the normal tissues from the tumour bed allows maximisation of the dose to the tumour while minimising the dose to normal tissues. This results in an improved therapeutic ratio with IORT. Although it was introduced in the 1960s, it has seen a resurgence of popularity with the introduction of self-shielding mobile linear accelerators and low-kV IORT devices, which by eliminating the logistical issues of transport of the patient during surgery for radiotherapy or building a shielded operating room, has enabled its wider use in the community...

Clinical Vignette: A 50-year-old woman presents to the emergency department with increasing abdominal pain. Abdominal computed tomography imaging reveals an expanded inferior vena cava-filling defect that is suspicious for a retroperitoneal sarcoma, possibly a primary leiomyosarcoma of the inferior vena cava. The surgery team discusses the case with the radiologist, and all agree that there are multiple challenges with obtaining a tissue diagnosis and determining resectability. Thus, it is decided that this patient should be discussed at a multidisciplinary case conference...

Leiomyosarcoma (LMS) is a rare but well-recognized malignant soft tissue sarcoma of smooth muscle origin. Metastases commonly occur in the lungs, liver, kidney, brain, and bone. Cases of metastatic osseous lesions or other extradural space-occupying masses secondary to LMS leading to neurologic compromise are relatively commonplace in the literature. Conversely, cases of intramedullary spinal cord metastasis (ISCM), an unusual entity as a sequela of any cancer, are exceedingly rare as a consequence of LMS. Only 2 cases of an ISCM from LMS are currently documented in the literature, and to the best of our knowledge, no case is described in the rehabilitation literature...

BACKGROUND AND OBJECTIVES: The volume-outcome relationship is well recognized. We sought to investigate this relationship in retroperitoneal sarcoma (RPS) surgery. METHODS: Non-metastatic RPS cases from 2004 to 2014 in the National Cancer Database were analyzed. Hospitals in the top 10th percentile for volume were defined as high-volume. Outcomes were selected a priori based on their known prognostic significance, including surgery use, R0/R1 resection, and R0 resection...

Soft tissue sarcomas are a rare and multifaceted group of solid tumours. Neoadjuvant chemotherapy is increasingly used to limit loss of function after wide surgical excision with the ultimate aim of improving patient survival. Recently, advances in the identification of effective treatment strategies and improvements in patient risk stratification have been reached. A randomized trial demonstrated that neoadjuvant epirubicin and ifosfamide improves survival of patients affected by five high-risk soft tissue sarcoma histologies of trunk and extremities, including undifferentiated pleomorphic sarcoma, myxoid liposarcoma, synovial sarcoma, malignant peripheral nerve sheath tumours, and leiomyosarcoma...

BACKGROUND: This is a unique case of neuropraxia of femoral nerve seen after resection of retroperitoneal liposarcoma which has not been reported before in the literature. INTRODUCTION: Neuropraxia, a transient paralysis due to blockage of nerve conduction, commonly associated with athletes and orthopedic procedures, has not been previously reported as a complication following resection of retroperitoneal sarcoma. CASE: This is an 81-year-old female who, on CT for evaluation of her atherosclerosis, was found to have an incidental right-sided retroperitoneal mass extending from the right renal capsule inferiorly through the inguinal canal...

BACKGROUND: The modified frailty index (mFI) is an important method to risk-stratify surgical patients and has been validated for general surgery and selected surgical subspecialties. However, there are currently no data assessing the efficacy of the mFI to predict acute morbidity and mortality in patients undergoing surgery for retroperitoneal sarcoma. METHODS: Using the American College of Surgeons' National Surgical Quality Improvement Program from 2007 to 2012, we performed a retrospective analysis of patients with a diagnosis of primary malignant retroperitoneal neoplasm who underwent surgical resection...

BACKGROUND: Primary tumors in the presacral (retrorectal) space are extremely rare in adults, with an estimated incidence of 0.0025 to 0.014 in large referral centers. Congenital varieties are most common and comprise two thirds of these tumors. Primary retroperitoneal sarcomas in the pelvic region are extremely rare. We report the ultrasound and the corresponding Computed Tomography (CT) features of a rare presacral fibrosarcoma in an adult woman, in whom the diagnosis was confirmed by a CT-guided biopsy...
