Machine Learning Predicts Oxaliplatin Benefit in Early Colon Cancer.

Purpose: A combination of fluorouracil, leucovorin, and oxaliplatin (FOLFOX) is the standard for adjuvant therapy of resected early-stage colon cancer (CC). Oxaliplatin leads to lasting and disabling neurotoxicity. Reserving the regimen for patients who benefit from oxaliplatin would maximize efficacy and minimize unnecessary adverse side effects.

Review of Safety Data for Adenovirus 5 as a Delivery Vector for Intratumoral Cancer Gene Therapy.

With efficient transduction across most cell types and larger packaging capacity, Adenovirus 5 (Ad5) makes an attractive choice as a viral vector. However, a reported past mortality and known immunogenicity cast doubt on the safety of its use. An online database search was performed for all clinical trials administering intratumoral injection of gene therapy packaged in Ad5, being conducted in the United States, and using the Common Terminology Criteria for Adverse Events (CTCAE).

Consensus statement and clinical pathway for the management of colon cancer with peritoneal metastases in the state of Delaware.

Background: Increasing data suggests that the combination of modern systemic therapies and Cytoreductive surgery with or without Hyperthermic Intraperitoneal Chemotherapy (HIPEC) may improve the outcome of patients with colon cancer with peritoneal metastases. Patient selection and sequence of treatments remains ill-defined.

Materials And Methods: A working group, the State of Delaware Peritoneal Surface Malignancies Task Force (DE-PSM-TF), was created including representatives from medical and surgical oncology from the acute care hospitals in Delaware.

NSABP FC-6: Surgical conversion rate in colorectal cancer patients with unresectable, KRAS wild-type liver metastases receiving mFOLFOX7 plus cetuximab.

Purpose: This study sought to determine the R0 resection rate in KRAS wild-type (WT), liver-only metastatic colorectal cancer (CRC) patients initially identified as having unresectable disease who were treated with FOLFOX7 plus cetuximab. Exploratory molecular analyses were undertaken before and after treatment.

Methods: Twenty patients were enrolled.

A cost analysis of sorafenib for desmoid tumors.

Introduction: A recent randomized trial demonstrated that sorafenib improved progression free survival (PFS) in patients with desmoid tumors despite many patients experiencing stable disease or spontaneous regression without treatment. Utilizing these trial data, we performed a cost analysis of sorafenib efficacy through two years of treatment.

Methods: Current Medicare Part D rates for sorafenib were utilized (dose 400 mg/day, cost $309/day).

A Population Health Assessment in a Community Cancer Center Catchment Area: Triple-Negative Breast Cancer, Alcohol Use, and Obesity in New Castle County, Delaware.

Background: The NCI requires designated cancer centers to conduct catchment area assessments to guide cancer control and prevention efforts designed to reduce the local cancer burden. We extended and adapted this approach to a community cancer center catchment area with elevated rates of triple-negative breast cancer (TNBC).

Methods: Cancer registry data for 462 TNBC and 2,987 "Not-TNBC" cases diagnosed between 2012 and 2020 at the Helen F.

Characteristics of Gastrointestinal Stromal Tumors incidentally discovered during abdominal surgery.

Background: Gastrointestinal Stromal Tumors (GISTs) are rare sarcomas with 5000 new cases arising in the United States each year. Despite their low incidence, general surgeons should be familiar with GISTs since a quarter of these neoplasms are encountered incidentally.

Methods: A retrospective medical records review was conducted to create a database of all GISTs resected from January 2005 to May 2019.

The disclosure slide-Informative or obligatory, 5 years of SSO Cancer Symposium oral presentations.

Background: Financial disclosure (FD) highlights potential conflicts of interest but is often overlooked at academic conferences.

Methods: Retrospective review of 2015-2019 Society of Surgical Oncology Cancer Symposium oral presentation slide and/or verbal FD frequency, duration, and content.

Results: Of 963 presentations, 331 (34%) omitted disclosure slide/verbalization.

Microbiome and colorectal cancer: A review of the past, present, and future.

The gastrointestinal tract is home to diverse and abundant microorganisms, collectively referred to as the microbiome. This ecosystem typically contains trillions of microbial cells that play an important role in regulation of human health. The microbiome has been implicated in host immunity, nutrient absorption, digestion, and metabolism.

A Comparison of Colectomy Outcomes Utilizing Open, Laparoscopic, and Robotic Techniques.

Introduction: Robotic colectomy could reduce morbidity and postoperative recovery over laparoscopic and open procedures. This comparative review evaluates colectomy outcomes based on surgical approach at a single community institution.

Methods: A retrospective review of all patients who underwent colectomy by a fellowship-trained colon and rectal surgeon at a single institution from 2015 through 2019 was performed, and a cohort developed for each approach (open, laparoscopic, and robotic).

Meta-Analysis on the Effect of Pasireotide for Prevention of Postoperative Pancreatic Fistula.

Background: A randomized controlled trial of routine administration of pasireotide demonstrated decreased incidence of clinically significant postoperative pancreatic fistula (POPF). Recent studies have not replicated these results. A meta-analysis was performed to evaluate its efficacy in this setting.

Meta-analysis on the Effect of Pasireotide for Prevention of Postoperative Pancreatic Fistula.

Background: A randomized controlled trial (RCT) of routine administration of pasireotide demonstrated decreased incidence of clinically significant postoperative pancreatic fistula (POPF). Recent studies have not replicated these results. A meta-analysis was performed to evaluate its efficacy in this setting.

Health-Care Workers' Perception of Reimbursement for Complex Surgical Oncology Procedures.

Perception of physician reimbursement for surgical procedures is not well studied. The few existing studies illustrate that patients believe compensation to be higher than in reality. These studies focus on patient perceptions and have not assessed health-care workers' views.

Pancreatic resections: 30 and 90-day outcomes in octogenarians.

Background: Pancreatic tumors are frequently found in a geriatric population. Given that the median age of patients with pancreatic cancer is 70 years at diagnosis and the ubiquity of CT and MRI imaging has increased the detection of pancreas masses, pancreatic surgeons often find themselves operating on patients of advanced age. This study sought to evaluate the outcomes of pancreatic resection in an octogenarian population at a single institution with a dedicated surgical oncology team.

Intergroup Randomized Phase III Study of Postoperative Oxaliplatin, 5-Fluorouracil, and Leucovorin Versus Oxaliplatin, 5-Fluorouracil, Leucovorin, and Bevacizumab for Patients with Stage II or III Rectal Cancer Receiving Preoperative Chemoradiation: A Trial of the ECOG-ACRIN Research Group (E5204).

Background: The addition of bevacizumab to chemotherapy improved outcomes for patients with metastatic colon cancer. E5204 was designed to test whether the addition of bevacizumab to mFOLFOX6, following neoadjuvant chemoradiation and definitive surgery, could improve overall survival (OS) in patients with stage II/III adenocarcinoma of the rectum.

Subjects, Materials, And Methods: Patients with stage II/III rectal cancer who had completed neoadjuvant 5-fluorouracil-based chemoradiation and had undergone complete resection were enrolled.

Precision Medicine in Colorectal Surgery.

This article reviews advances in precision medicine for colorectal carcinoma that have influenced screening and treatment, and potentially prevention. Advances in molecular techniques have made it possible for better patient selection for therapies; therefore, mutational analysis should be performed at diagnosis to guide treatment. Future efforts should focus on validating these treatments in specific subgroups and on understanding the mechanisms of resistance to therapies to enable treatment optimization, promote efficacy, and reduce treatment costs and toxicities.

High volume pancreaticoduodenectomy performed at an academic community cancer center.

Background: We sought to evaluate the post-operative outcomes of patients undergoing pancreaticoduodenectomy at a high volume academic community cancer center.

Methods: A retrospective review was performed of patients undergoing pancreaticoduodenectomy over a 10-year period.

Results: Over 10 years, 213 patients underwent pancreaticoduodenectomy.
