BACKGROUND: Undifferentiated pleomorphic sarcoma (UPS) is a relatively rare but aggressive neoplasm. We sought to utilize a multi-institutional US cohort of sarcoma patients to examine predictors of survival and recurrence patterns after resection of UPS. METHODS: From 2000 to 2016, patients with primary UPS undergoing curative-intent surgical resection at seven academic institutions were retrospectively reviewed. Epidemiologic and clinicopathologic factors were reviewed by site of origin...

Surgeons face unique challenges in perioperative decision-making and communication with patients and families. In cardiothoracic surgery, the stakes are high, life and death decisions must be made quickly, and surgeons often lack a longstanding relationship with patients and families prior to intervention. This review considers specific challenges in the preoperative period followed by those faced postoperatively. While preoperative deliberation and informed consent focus on reaching a decision between 2 or more alternative approaches, the most vexing postoperative decisions often involve the patient's discontent with the best-case outcome or how to ensure goal-concordant care when complications arise...

BACKGROUND: Reported outcomes after surgical debulking in patients with advanced neuroendocrine tumor liver metastases (NETLM) are sparse. METHODS: NETLM patients that underwent surgical debulking from 2019 to 2021 were reviewed. Trends in perioperative liver function, complications, symptom response, and progression-free survival were examined. RESULTS: 1069 liver lesions were debulked from 53 patients using a combination of parenchymal-sparing resections (PSR) and ultrasound-guided microwave ablations (MWA)...

BACKGROUND: In gastric cancer (GC) patients without imaging evidence of distant metastasis, diagnostic staging laparoscopy (DSL) is recommended to detect radiographically occult peritoneal metastasis (M1). DSL carries a risk for morbidity and its cost-effectiveness is unclear. Use of endoscopic ultrasound (EUS) to improve patient selection for DSL has been proposed but not validated. We aimed to validate an EUS-based risk classification system predicting risk for M1 disease. METHODS: We retrospectively identified all GC patients without positron emission tomography (PET)/computed tomography (CT) evidence of distant metastasis who underwent staging EUS followed by DSL between 2010 and 2020...

Despite high mortality rates from gastric cancer, surgical management remains critical for curative potential. Optimal outcomes of gastric cancer resection depend on a multitude of variables, including the extent of resection, scope of lymphadenectomy, method of reconstruction, and potential for a minimally invasive approach. Laparoscopic gastrectomy, compared with open gastrectomy, has been analyzed in numerous randomized control trials. Generally, those trials demonstrated statistically similar postoperative complication rates, mortality, and oncologic outcomes between the two approaches...

BACKGROUNDS AND OBJECTIVES: This investigation described clinicopathological features and outcomes of extraskeletal myxoid chondrosarcoma (EMC) patients. METHODS: EMC patients were identified from the United States Sarcoma Collaborative database between 2000 and 2016. Overall survival (OS) and recurrence-free survival (RFS) were calculated, and prognostic factors were analyzed. RESULTS: Sixty individuals with a mean age of 55 years were included, and 65...

BACKGROUND: Patient-physician communication is key to better clinical outcomes and patient well-being. Communication between trauma patients and their physicians remains relatively unexplored. We aimed to identify and characterize the range of strengths and challenges in patient-physician communication in the setting of trauma care. METHODS: A qualitative, grounded theory approach was used to explore communication strengths and challenges for patients and residents...

BACKGROUND: Despite advances in surgical technique, bile leak remains a common complication following hepatectomy. We sought to identify incidence of, risk factors for, and outcomes associated with biliary leak. STUDY DESIGN: This is an ACS-NSQIP study. Distribution of bile leak stratified by surgical approach and hepatectomy type were identified. Univariate and multivariate factors associated with bile leak and outcomes were evaluated. RESULTS: Robotic hepatectomy was associated with less bile leak (5...

BACKGROUND: Robotic surgery has seen exponential growth over the past several years. However, there is no standardized training program implemented nationwide. Thus, there is a challenge in how to measure surgical proficiency and how to train future surgeons. METHODS: In this study, all PGY3 general surgery residents from the University of Chicago residency program were assigned the curriculum. The curriculum consisted of seven sections: instrument mastery, simulation curriculum, suturing, inanimate drills, laparoscopic/open comparisons, surveys, mentor sessions, and exposure in the operating room...

BACKGROUND: Prognostic nomograms for patients with resected extremity soft tissue sarcoma (STS) include the Sarculator and Memorial Sloan Kettering (MSKCC) nomograms. We sought to validate these two nomograms within a large, modern, multi-institutional cohort of resected primary extremity STS patients. METHODS: Resected primary extremity STS patients from 2000 to 2017 were identified across nine high-volume U.S. institutions. Predicted 5- and 10-year overall survival (OS) and distant metastases cumulative incidence (DMCI), and 4-, 8-, and 12-year disease-specific survival (DSS) were calculated with Sarculator and MSKCC nomograms, respectively...

BACKGROUND: Metastatic adenocarcinomas of foregut origin are aggressive and have limited treatment options, poor quality of life, and a dismal prognosis. A subset of such patients with limited metastatic disease might have favorable outcomes with locoregional metastasis-directed therapies. This study investigates the role of sequential cytoreductive interventions in addition to the standard of care chemotherapy in patients with oligometastatic foregut adenocarcinoma. METHODS: This is a single-center, phase II, open-label randomized clinical trial...

BACKGROUND: Well-differentiated liposarcoma (WDLPS) is a low-grade soft tissue sarcoma with a propensity for local recurrence. The necessity of obtaining microscopically free surgical margins (R0) to minimize local recurrence is not clear. This study evaluates recurrence-free survival (RFS) of extremity WDLPS in relation to resection margin status. METHODS: A retrospective review of adult patients with primary extremity WDLPS at seven US institutions from 2000 to 2016 was performed...

BACKGROUND: Surgical resection for sarcoma lung metastases has been associated with improved overall survival (OS). METHODS: Patients who underwent curative-intent resection of sarcoma lung metastases (2000-2016) were identified from the US Sarcoma Collaborative. Patients with extrapulmonary metastatic disease or R2 resections of primary tumor or metastases were excluded. Primary endpoint was OS. RESULTS: Three hundred and fifty-two patients met inclusion criteria...

BACKGROUND AND OBJECTIVES: Prognostic nomograms for patients undergoing resection of retroperitoneal sarcoma (RPS) include the Sarculator and Memorial Sloan Kettering (MSK) sarcoma nomograms. We sought to validate the Sarculator and MSK nomograms within a large, modern multi-institutional cohort of patients with primary RPS undergoing resection. METHODS: Patients who underwent resection of primary RPS between 2000 and 2017 across nine high-volume US institutions were identified...

BACKGROUND: The authors hypothesized that cytoreductive surgery (CRS, comprising gastrectomy combined with metastasectomy) in addition to systemic chemotherapy (SC) is associated with a better survival than chemotherapy alone for patients with metastatic gastric adenocarcinoma (MGA). METHODS: Patients with MGA who received SC between 2004 and 2016 were identified using the National Cancer Database (NCDB). Nearest-neighbor 1:1 propensity score-matching was used to create comparable groups...

Melanotic schwannoma is a rare nerve sheath tumor composed of melanin-producing Schwann cells with the potential for metastasis. These tumors can be associated with familial tumor syndromes and can cause significant symptoms related to nerve compression and mass effect. Due to the rarity of these lesions, they can be initially misidentified as melanocytomas, pigmented dermatofibrosarcoma protuberans, neurofibromas or malignant melanomas. Surgical excision is the mainstay of treatment with limited benefit from adjuvant systemic chemotherapy or radiation...

The one-year and median overall survival (mOS) rates of advanced gastroesophageal adenocarcinomas (GEA) are ∼50% and <12 months, respectively. Baseline spatial and temporal molecular heterogeneity of targetable alterations may be a cause of failure of targeted/immunooncologic therapies. This heterogeneity, coupled with infrequent incidence of some biomarkers, has resulted in stalled therapeutic progress. We hypothesized that a personalized treatment strategy, applied at first diagnosis then serially over up to three treatment lines using monoclonal antibodies combined with optimally sequenced chemotherapy, could contend with these hurdles...

BACKGROUND: The optimal margin of resection for high-grade extremity sarcomas and its impact on survival has long been questioned in the setting of adjuvant radiotherapy. The objective of this study was to investigate the impact of resection status on recurrence and survival. METHODS: All patients with primary, nonmetastatic, high-grade extremity sarcomas that underwent surgical resection from January 2000 to April 2016 in the U.S. Sarcoma Collaborative (USSC) were retrospectively reviewed...
