Accuracy of nodal staging is influenced by sidedness in colon cancer.

Background: Adequate lymph node (LN) sampling is critical for accurate nodal staging in colon cancer (CC), particularly for T3N0 disease as current guidelines recommend considering adjuvant chemotherapy when less than 12 LNs are examined. The impact of sidedness on nodal staging accuracy in patients with T3N0 disease has not been previously studied.

Methods: Patients with pathologic T3 CC were identified from a prospective multicenter international trial of ultrastaging in CC.

Effect of 3-Dimensional Virtual Reality Models for Surgical Planning of Robotic-Assisted Partial Nephrectomy on Surgical Outcomes: A Randomized Clinical Trial.

Importance: Planning complex operations such as robotic-assisted partial nephrectomy requires surgeons to review 2-dimensional computed tomography or magnetic resonance images to understand 3-dimensional (3-D), patient-specific anatomy.

Objective: To determine surgical outcomes for robotic-assisted partial nephrectomy when surgeons reviewed 3-D virtual reality (VR) models during operative planning.

Design, Setting, And Participants: A single-blind randomized clinical trial was performed.

Implications of Prolonged Time to Pancreaticoduodenectomy After Neoadjuvant Chemoradiation.

Background: For patients with pancreatic adenocarcinoma (PA), the optimal time interval between neoadjuvant chemoradiation (CR) to surgical resection has not been well established.

Methods: The National Cancer Database from 2006 to 2014 was queried for patients ≥18 y old diagnosed with PA who received neoadjuvant CR. Survival and short-term outcomes were compared between patients who had pancreaticoduodenectomy ≤12 wk and >12 wk after completion of CR.

Clinicopathological Features of Triple-Negative Breast Cancer Epigenetic Subtypes.

Background/objective: Triple-negative breast cancer (TNBC) is a heterogeneous collection of breast tumors with numerous differences including morphological characteristics, genetic makeup, immune-cell infiltration, and response to systemic therapy. DNA methylation profiling is a robust tool to accurately identify disease-specific subtypes. We aimed to generate an epigenetic subclassification of TNBC tumors (epitypes) with utility for clinical decision-making.

Colon cancer as a subsequent malignant neoplasm in young adults.

Background: The incidence of colon cancer (CC) is rising in younger adults and can occur de novo or in patients previously treated for another cancer. To the authors' knowledge, the impact on survival of CC occurring as a subsequent malignant neoplasm (SMN) has not been described for younger patients, which the authors anticipate to be lower with SMNs than that of primary CC.

Methods: Patients aged <50 years with CC in the 2004 through 2014 National Cancer Data Base were identified.

Preoperative Ultrasound Assessment of Regional Lymph Nodes in Melanoma Patients Does not Provide Reliable Nodal Staging: Results From a Large Multicenter Trial.

Objective: To assess whether preoperative ultrasound (US) assessment of regional lymph nodes in patients who present with primary cutaneous melanoma provides accurate staging.

Background: It has been suggested that preoperative US could avoid the need for sentinel node (SN) biopsy, but in most single-institution reports, the sensitivity of preoperative US has been low.

Methods: Preoperative US data and SNB results were analyzed for patients enrolled at 20 centers participating in the screening phase of the second Multicenter Selective Lymphadenectomy Trial.

Propensity-Matched Comparison of Oral Anticoagulation Versus Antiplatelet Therapy After Left Atrial Appendage Closure With WATCHMAN.

Objectives: In this propensity-matched analysis of post-left atrial appendage closure antithrombotic therapy, the safety and effectiveness of oral anticoagulation (OAC) and antiplatelet therapy (APT) were compared.

Background: Left atrial appendage closure with the WATCHMAN device is an alternative to OAC in patients with nonvalvular atrial fibrillation, who are at high bleeding risk. Initial trials included 45 days of post-implantation OAC, but registry data suggest that APT may suffice.

Pancreatic islet cell tumors in adolescents and young adults.

Background: Pancreatic islet cell tumors are rare in adolescents, and most studies published to date focus on older patients. We utilized a national database to describe the histology and clinical pattern of pancreatic islet cell tumors in adolescent and young adult (AYA) patients, and to compare AYAs to older adults. We hypothesized that AYAs with pancreatic islet cell tumors would have better overall survival.

Pediatric gastric adenocarcinoma: A National Cancer Data Base review.

Purpose: We sought to compare the presentation, management, and outcomes in gastric adenocarcinoma cancer for pediatric and adult patients.

Methods: Using the 2004 to 2014 National Cancer Database (NCDB), patients ≤21 years (pediatric) were retrospectively compared to >21 years (adult). Chi-squared tests were used to compare categorical variables, and Cox regression was used to estimate hazard ratios (HR) for survival differences.

Time from definitive therapy to onset of metastatic disease predicts outcomes in men with metastatic hormone sensitive prostate cancer.

Purpose: Contemporary treatment for metastatic hormone sensitive prostate cancer (mHSPC) includes androgen deprivation therapy (ADT) plus abiraterone or docetaxel. While these intensified regimens have improved efficacy, they are also associated with increased cost and toxicities. Not all men with mHSPC may be candidates for these intensified regimens, yet there are no clinical models or biomarkers used to optimize treatment selection.

Investigational drug therapies currently in early-stage clinical development for the treatment of clostridioides (clostridium) difficile infection.

Introduction: Clostridioides (Clostridium) difficile Infection (CDI) is an urgent global threat causing ~500,000 infections annually in the United States of America (USA) and is associated with a 36% 30-day attributable mortality rate. Despite the availability of three therapeutic agents, CDI recurrence occurs in 20-40% of patients, with a 30-40% second recurrence rate in these patients. Consequently, there is a need for novel agents for treating CDI.

Current Imaging Modalities Understage One-Third of Patients with Stage I Rectal Cancer: Implications for Treatment Selection.

Accurate preoperative clinical staging is essential to optimize the treatment of rectal cancer. Primary surgical resection is typically indicated for stage I disease, whereas neoadjuvant therapy is recommended for stages II and III. The objective of this study is to examine the accuracy of clinical staging using current imaging modalities in predicting pathologic stage and, thus, selecting appropriate treatment.

The role of thoracoscopic pneumonectomy in the management of non-small cell lung cancer: A multicenter study.

Objective: The objective of this study was to evaluate the impact of the video-assisted thoracoscopic (VATS) approach on the outcomes of patients who underwent pneumonectomy.

Methods: The effect of the surgical approach on perioperative complications and survival in patients who underwent pneumonectomy for nonmetastatic non-small cell lung cancer across 3 institutions (2000-2016) was assessed using multivariable logistic regression, Cox proportional hazards analysis, and propensity-score matching. Completion pneumonectomies were excluded from this study, and an "intent-to-treat" analysis was performed.

Visual Field Outcome Reporting in Neurosurgery: Lessons Learned from a Prospective, Multicenter Study of Transsphenoidal Pituitary Surgery.

Objective: Visual field (VF) outcomes are commonly reported in neurosurgical case series; however, substantial variability can exist in VF testing and outcome reporting. We aimed to evaluate the challenges of VF testing and to develop detailed recommendations for VF outcome reporting by analyzing results from an ongoing, multicenter study of transsphenoidal pituitary surgery.

Methods: VF testing results were collected during a prospective, multicenter clinical trial evaluating patient outcomes after transsphenoidal surgery for nonfunctioning pituitary adenomas (TRANSSPHER).

Both the intratumoral immune and microbial microenvironment are linked to recurrence in human colon cancer: results from a prospective, multicenter nodal ultrastaging trial.

Colon cancer (CC) is the third most common cancer diagnosed in the United States and the incidence has been rising among young adults. We and others have shown a relationship between the immune infiltrate and prognosis, with improved disease-free survival (DFS) being associated with a higher expression of CD8 T cells. We hypothesized that a microbial signature might be associated with intratumoral immune cells as well as DFS.

Correlation Between Clinical and Pathologic Staging in Colon Cancer: Implications for Neoadjuvant Treatment.

Background: Recent randomized trials suggest improved outcomes in patients with locally advanced colon cancer (LACC) treated with neoadjuvant chemotherapy (NAC). Optimal selection of patients for NAC depends on accurate clinical staging. The purpose of this study was to examine the degree of correlation between clinical and pathologic staging in patients with colon cancer (CC).

A single-center, pilot study evaluating a novel TriHex peptide- and botanical-containing eye treatment compared to baseline.

Background: Topical treatments containing tripeptide and hexapeptide (TriHex technology) have been proven to contribute to youthful skin by clearing the extracellular matrix and stimulating collagen and elastin production.

Objective: Evaluate the efficacy of a novel eye treatment containing TriHex peptides and other synergistic ingredients for the daily treatment of fine lines/crow's feet around the eyes, under eye hollowing, under eye bags, and dark circles.

Patients/methods: In this study, 10 subjects (9 female and 1 male) aged 30-60 of Fitzpatrick skin type I, II, or III were selected to use an eye treatment containing TriHex peptides and active botanicals (Alastin Restorative Eye Treatment with TriHex Technology™, ALASTIN Skincare, Inc.

Disparities in fertility-sparing surgery in adolescent and young women with stage I ovarian dysgerminoma.

Background: In many cancers, racial and socioeconomic disparities exist regarding the extent of surgery. For ovarian dysgerminoma, fertility-sparing (FS) surgery is recommended whenever possible. The aim of this study was to investigate rates of FS versus non-fertility-sparing (NFS) procedures for stage I ovarian dysgerminoma in adolescents and young adults (AYAs) by ethnicity/race and socioeconomic status.

Technical particularities of joint preserving hip surgery in osteopetrosis.

Proximal femoral fracture and coxarthrosis are the most common orthopaedic problems of osteopetrosis. Fracture fixation is difficult and one-third fail, with total hip replacement as the final solution. There is little reported experience about how to deal with this particular type of bone and what has been published to date is surprisingly non-specific.

5-Year Outcomes After Left Atrial Appendage Closure: From the PREVAIL and PROTECT AF Trials.

Background: The PROTECT AF (WATCHMAN Left Atrial Appendage System for Embolic Protection in Patients With Atrial Fibrillation) trial demonstrated that left atrial appendage closure (LAAC) with the Watchman device (Boston Scientific, St. Paul, Minnesota) was equivalent to warfarin for preventing stroke in atrial fibrillation, but had a high rate of complications. In a second randomized trial, PREVAIL (Evaluation of the WATCHMAN LAA Closure Device in Patients With Atrial Fibrillation Versus Long Term Warfarin Therapy), the complication rate was low.

Testicular tumors in prepubescent patients.

Background/purpose: Pediatric testicular tumors are rare, constituting only 1% of all pediatric solid tumors. Single-institution studies addressing pediatric testicular tumors published to date have been limited in the number of patients.

Methods: We utilized the National Cancer Data Base (1998-2012) to review all prepubescent patients (≤12 years old) with testicular neoplasms.

Socioeconomic disparities affect survival in malignant ovarian germ cell tumors in AYA population.

Background: Malignant ovarian germ cell tumors (MOGCTs) are a rare form of ovarian malignancy. Socioeconomic status (SES) has been shown to affect survival in several gynecologic cancers. We examined whether SES impacted survival in adolescent and young adults (AYAs) with MOGCT.
