INTRODUCTION: Breast-conserving therapy (BCT) using oncoplastic surgery (OPS) allows for larger resections and improved aesthetics though volume redistribution and tissue rearrangement. Data regarding the impact of OPS on surveillance imaging and need for additional biopsies are limited. METHODS: This observational cohort underwent BCT at a single institution from 2009 to 2018; standard breast-conserving surgery (BCS) was the predominant approach until OPS was introduced in 2012. Rates of imagin...

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are often indolent; however, identifying patients at risk for rapidly progressing variants is critical, particularly for those with small tumors who may be candidates for expectant management. Specific growth rate (SGR) has been predictive of survival in other malignancies but has not been examined in PNETs. METHODS: A retrospective cohort study of adult patients who underwent PNET resection from 2000 to 2016 was performed utilizing the multi-...

BACKGROUND: As neoadjuvant therapy of borderline resectable pancreatic cancer (BRPC) is becoming more widely utilized, better indicators of progression are needed to help guide therapeutic decisions. METHODS: A retrospective review was performed on all patients with BRPC who received 24 weeks of neoadjuvant chemotherapy. Patients with chemotoxicity or medical comorbidities limiting treatment completion and non-expressors of CA19-9 were excluded. Serum CA19-9 response was analyzed as a predictor ...

Background The role of routine lymphadenectomy in the surgical treatment of pancreatic neuroendocrine tumors (pNET) remains poorly defined. The objective of the current study was to investigate trends in the number of lymph nodes (LN) evaluated for pNET treatment at a nationwide level.

BACKGROUND: Insurance status predicts access to medical care in the USA. Previous studies have shown uninsured patients with some malignancies have worse outcomes than insured patients. The impact of insurance status on patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is unclear. PATIENTS AND METHODS: A retrospective cohort study of adult patients with resected GEP-NETs was performed using the US Neuroendocrine Tumor Study Group (USNETSG) database (2000-2016). Demographic an...

BACKGROUND AND OBJECTIVES: We sought to define the incidence and impact of Textbook Outcome (TO) on disease-free survival [DFS] among patients undergoing resection of pancreatic neuroendocrine tumors (PNET). METHODS: Patients undergoing resection of a PNET between 2000 and 2016 were identified using a multi-institutional database. TO was defined as no postoperative severe complications (Clavien-Dindo grade >/= III), no 90-day mortality, no prolonged length-of-hospital stay (LOS) (ie, > 75th perc...

BACKGROUND AND OBJECTIVES: Lack of high-level evidence supporting adjuvant therapy for patients with resected gastroenteropancreatic neuroendocrine tumors (GEP NETs) warrants an evaluation of its non-standard of care use. METHODS: Patients with primary GEP NETs who underwent curative-intent resection at eight institutions between 2000 and 2016 were identified; 91 patients received adjuvant therapy. Recurrence-free survival (RFS) and overall survival (OS) were compared between adjuvant cytotoxic ...

BACKGROUND: Somatostatin analog functional imaging with gallium-68 (Ga-68) dotatate positron emission tomography/computed tomography (PET/CT) has demonstrated superiority in lesion detection in patients with neuroendocrine tumors (NETs). The clinical impact of this imaging modality on US surgical and medical oncology practices has not been established. METHODS: Consecutive patients with NET at our institution who received an initial Ga-68 dotatate PET/CT between July 2017 and September 2018 were...

BACKGROUND: The adoption of spleen-preserving distal pancreatectomy (SPDP) for malignant disease such as pancreatic neuroendocrine tumors (pNETs) has been controversial. The objective of the current study was to assess the impact of SPDP on outcomes of patients with pNETs. METHODS: Patients undergoing a distal pancreatectomy (DP) for pNET between 2002 and 2016 were identified in the U.S. Neuroendocrine Tumor Study Group database. Propensity score matching (PSM) was used to compare short- and lon...

Abstract Low grade tumors located in the neck of the pancreas present a unique surgical challenge. Subtotal pancreatectomy results in significant loss of pancreatic gland and function, while pancreaticoduodenectomy may be too aggressive for these lesions. We present a case of a patient with a well differentiated neuroendocrine tumor in the neck of the pancreas who underwent a central pancreatectomy with pancreaticogastrostomy reconstruction. Patient selection and technical aspects of the procedu...
