Background: This study sought to determine whether adjuvant chemotherapy (AC) compared to no AC (noAC) after neoadjuvant chemoradiation (CRT) and resection for rectal adenocarcinoma prolongs survival. Current guidelines from expert groups are conflicting, and data to support administering AC to patients who received neoadjuvant CRT are lacking.
Methods: A total of 19,867 patients met inclusion/exclusion criteria.
Background: The effect of minimally invasive pancreaticoduodenectomy (MIPD), including laparoscopic and robotic pancreaticoduodenectomy (LPD and RPD, respectively), on compliance and time to return to intended oncologic therapy (RIOT) for pancreatic ductal adenocarcinoma (PDAC) remains unknown.
Patients And Methods: Patients with nonmetastatic PDAC were analyzed in the National Cancer Database (NCDB). Three groups were matched per propensity score: open pancreaticoduodenectomy (OPD) and MIPD, LPD and RPD, and converted and nonconverted patients.
Background: The evidence assessing the additional benefits of adjuvant chemotherapy (AC) following neoadjuvant therapy (NAT; i.e. chemotherapy or chemoradiotherapy) and oesophagectomy for oesophageal adenocarcinoma (EAC) are limited.
View Article and Find Full Text PDFBackground: Outcomes of rectal adenocarcinoma vary considerably. Composite "textbook oncologic outcome" (TOO) is a single metric that estimates optimal clinical performance for cancer surgery.
Methods: Patients with stage II/III rectal adenocarcinoma who underwent single-agent neoadjuvant chemoradiation and proctectomy within 5-12 weeks were identified in the National Cancer Database (NCDB).
Background: Data supporting routine use of adjuvant chemotherapy (AC) compared to no AC (noAC) for perihilar cholangiocarcinoma (hCCA) is unclear. This study aimed to determine whether AC improves long-term survival following resection for hCCA.
Methods: Patients receiving resection for hCCA followed by AC or no AC from 2010 to 2016 were identified from the National Cancer Database (NCDB).
Background: Data supporting routine use of adjuvant radiotherapy (RT) compared to without RT (noRT) for gallbladder cancer (GBC) is unclear. This study aimed to determine whether RT improves long-term survival following resection for GBC.
Methods: Patients receiving resection for GBC followed by RT from 2004 to 2016 were identified from the National Cancer Database (NCDB).
Background: The impact of palliative gastrectomy for metastatic gastric adenocarcinoma, especially by site of metastasis remains unclear.
Methods: The National Cancer Database, 2010-2015, was used to identify patients with clinical metastatic (cM1) gastric adenocarcinoma (n = 19,411) at diagnosis. The main variable was index management for cM1 gastric adenocarcinoma (ie, no treatment, palliative chemotherapy, or palliative gastrectomy).
Background: Biopsy to achieve tissue diagnosis (TD) of hepatocellular carcinoma (HCC) risks needle tract seeding. With chest wall and peritoneal recurrences reported, TD could worsen cancer outcomes. We investigated HCC outcomes after TD compared to clinical diagnosis (CD), hypothesizing that TD adversely affects overall survival (OS).
View Article and Find Full Text PDFBackground: Data supporting the routine use of adjuvant chemotherapy (AC) compared with no AC (noAC) following neoadjuvant chemotherapy (NAC) and resection for pancreatic ductal adenocarcinoma (PDAC) are lacking. This study aimed to determine whether AC improves long-term survival in patients receiving NAC and resection.
Methods: Patients receiving resection for PDAC following NAC from 2004 to 2016 were identified from the National Cancer Data Base (NCDB).
Background: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been associated with significant morbidity and increased hospital length of stay (LOS). The authors report their experience after implementation of an enhanced recovery after surgery (ERAS) program for CRS-HIPEC.
Methods: Outcomes were analyzed before and after ERAS implementation.
Background: The role of endoscopic resection (ER) in the management of subsets of clinical T1N0 gastric adenocarcinoma remains controversial. The aim of this study was to evaluate the outcome of ER versus gastrectomy in node-negative cT1a and cT1b gastric adenocarcinoma.
Methods: Data from the National Cancer Database (2010-2015) were used to identify patients with clinical T1aN0 (n = 2927; ER: n = 1157, gastrectomy: n = 1770) and T1bN0 (n = 2915; ER: n = 474, gastrectomy: n = 2441) gastric adenocarcinoma.
Introduction: Despite neoadjuvant chemotherapy (NAC) being increasingly utilized and possibly associated with improved oncological outcomes, the impact of NAC on textbook outcomes following pancreatectomy for pancreatic ductal adenocarcinoma (PDAC) remains debated.
Methods: A retrospective review of the National Cancer Database of patients undergoing resection of non-metastatic PDAC from 2004 to 2016 was performed. Propensity score matching was used to account for treatment selection bias in patients with and without NAC (noNAC).
Introduction: Postoperative pancreatic fistula (POPF) drives morbidity and mortality following pancreatectomy. Use of neoadjuvant chemotherapy (NAC) has recently increased in the treatment of potentially resectable pancreatic ductal adenocarcinoma (PDAC). This study examined the effect of NAC on POPF rates and postoperative outcomes in PDAC.

On the other hand, the prevalence of obesity is also increasing and expected to reach unprecedented rates in the upcoming decades. Therefore, managing patients on either extreme of the body mass index (BMI) range is anticipated to become a routine challenge and it becomes imperative to understand the impact of BMI, as a spectrum, on the long-term outcomes of CRS and HIPEC.

Methods: The NSQIP esophagectomy-targeted database during 2-year period was used. Only patients who underwent elective TTE for oncologic indications were included.
Background: With the introduction of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), long-term survival can be achieved in selected patients with peritoneal surface malignancy. In patients with peritoneal sarcomatosis (PS), CRS/HIPEC remains a topic of debate. It is important that patient selection and outcome be improved with a tool that better predicts survival in such patients.

The incidence, risk factors, and outcomes of AKI following other types of major surgeries have not been as well characterized. We sought to study the incidence of AKI following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) per the Kidney Disease: Improving Global Outcomes (KDIGO) criteria.
View Article and Find Full Text PDFNutrition's impact on the surgical outcome has been established in various surgical specialties. However, data addressing the nutritional aspect following surgery for peritoneal surface malignancies are considered scarce. We aim to evaluate the knowledge, attitudes, and practice of surgeons regarding their nutritional support for patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC) via a survey directed to self-evaluate nutritional knowledge, screening, and practice toward patients.
View Article and Find Full Text PDFBackground: In light of the modern surgical trend towards minimally invasive surgery, we aim to assess the feasibility of hand-assisted laparoscopic (HAL) cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in peritoneal surface malignancy (PSM).
Methods: Patients with PSM secondary to colorectal cancer or pseudomyxoma peritonei with peritoneal cancer index (PCI) of ≤ 10 were considered for HAL CRS and HIPEC. One patient had PCI of 15 but based on the disease distribution laparoscopic-assisted CRS and HIPEC was thought to be feasible, thus was also included.
The current standard of treatment for malignant peritoneal mesothelioma (MPM) is cytoreductive surgery when the disease distribution is favorable. The role of chemotherapy, as an adjunct to surgery, remains unclear. The national database of mesothelioma was used to identify MPM patients who were treated with curative intent.
View Article and Find Full Text PDFBackground: As cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are being increasingly adopted as the standard treatment for peritoneal surface malignancies, familiarity with this procedure's adverse events is also growing. Herein, we describe an unreported adverse event of exocrine pancreatic insufficiency (EPI) following CRS and HIPEC.
Patients And Methods: Patients who underwent CRS and HIPEC between 9/2016 and 9/2017 were prospectively recruited.
Introduction: The extent of lymphadenectomy in the surgical treatment of gastric cancer is a topic of controversy among surgeons. This study was conducted to analyze the American National Cancer Database (NCDB) and conclude the optimal extent of lymphadenectomy for gastric adenocarcinoma.
Methods: The NCDB for gastric cancer was utilized.
