Trends in Immunotherapy (IO) Use and Survival Among Patients With High-Incidence Stage IV Cancers Across the United States.

Background And Objectives: IO has transformed cancer management, but its adoption in advanced cancer patients varies by tumor type. With more Stage IV patients undergoing surgery, understanding site-specific outcomes in these challenging patients is essential. We aimed to evaluate IO use and survival trends for Stage IV cancer patients across high-incidence cancers in the US.

The associations of food environment with gastrointestinal cancer outcomes in the United States.

Background: Social conditions and dietary behaviors have been implicated in the rising burden of gastrointestinal cancers (GIC). The "food environment" reflects influences on a community level relative to food availability, nutritional assistance, and social determinants of health. Using the US Department of Agriculture-Food Environment Atlas (FEA), we sought to characterize the association of food environment on GIC presenting stage and long-term survival.

Associations of social vulnerability with truncal and extremity melanomas in the United States.

Background: Prior studies in social determinants (SDoH) of truncal-extremity melanomas (TEM) have analyzed race, income, and environmental factors relative to their effect on health disparities. However, they are limited by the narrow scopes of SDoH and study population, while lacking analyses of interrelational contribution of SDoH on TEM disparities.

Methods: This retrospective cohort study of adult TEM patients (1975-2017) assessed linear regression trends in months of survival, as well as logistic regression trends in advanced presenting stage, surgery, and chemotherapy receipt across TEM subtypes with increasing overall social vulnerability and vulnerability in 15 SDoH variables grouped into socioeconomic status (SES), minority-language status (ML), household composition (HH), and housing-transportation (HT) themes measured by the SVI.

Routine imaging guided by a 31-gene expression profile assay results in earlier detection of melanoma with decreased metastatic tumor burden compared to patients without surveillance imaging studies.

Patients with early-stage disease typically have a good prognosis, but still have a risk of recurrence, even with negative sentinel lymph node biopsy (SLNB). This study explores the utility of routine imaging to detect metastases in patients with negative SLNB but high-risk 31 gene expression profile (31-GEP) scores. We retrospectively identified melanoma patients with negative SLNBs.

Therapeutic Value of Sentinel Lymph Node Biopsy in Patients With Melanoma: A Randomized Clinical Trial.

Importance: Sentinel lymph node (SLN) biopsy is a standard staging procedure for cutaneous melanoma. Regional disease control is a clinically important therapeutic goal of surgical intervention, including nodal surgery.

Objective: To determine how frequently SLN biopsy without completion lymph node dissection (CLND) results in long-term regional nodal disease control in patients with SLN metastases.

Oncologic Outcomes of Multi-Institutional Minimally Invasive Inguinal Lymph Node Dissection for Melanoma Compared with Open Inguinal Dissection in the Second Multicenter Selective Lymphadenectomy Trial (MSLT-II).

Background: Minimally invasive inguinal lymphadenectomy (MILND) is safe and feasible, but limited data exist regarding oncologic outcomes.

Methods: This study performed a multi-institutional retrospective cohort analysis of consecutive MILND performed for melanoma between January 2009 and June 2016. The open ILND (OILND) comparative cohort comprised patients enrolled in the second Multicenter Selective Lymphadenectomy Trial (MSLT-II) between December 2004 and March 2014.

Higher rates of regional disease but improved outcomes in pediatric versus adult melanoma.

Background: Malignant melanoma is rare in the pediatric population and management is largely extrapolated from adult guidelines. Adult data have shown that immediate completion lymph node dissection (CLND) does not improve overall survival in selected patients with clinically node negative, sentinel lymph node-positive disease. Current nodal management in children is unknown.

TVB-2640 (FASN Inhibitor) for the Treatment of Nonalcoholic Steatohepatitis: FASCINATE-1, a Randomized, Placebo-Controlled Phase 2a Trial.

Background & Aims: Increased de novo lipogenesis creates excess intrahepatic fat and lipotoxins, propagating liver damage in nonalcoholic steatohepatitis. TVB-2640, a fatty acid synthase inhibitor, was designed to reduce excess liver fat and directly inhibit inflammatory and fibrogenic pathways. We assessed the safety and efficacy of TVB-2640 in patients with nonalcoholic steatohepatitis in the United States.

Risk factors and patterns of recurrence after sentinel lymph node biopsy for thin melanoma.

While having a thin melanoma (defined as AJCC 8 T1 stage tumor ≤ 1.0 mm) with negative sentinel lymph node biopsy (SLNB) provides an excellent prognosis, some patients still develop recurrence and die. To determine risk factors for any recurrence (local/in-transit, nodal, distant) in thin melanoma patients with negative SLNB and assess survival outcomes.

Surgical approach, management, and oncologic outcomes of primary leiomyosarcoma of the inferior vena cava: An institutional case series.

Background: Leiomyosarcoma of the inferior vena cava (IVC) is a rare tumor arising from the smooth muscle of vessel walls. Surgery is the only potential curative treatment. Given its rarity, optimal surgical, and oncologic management is not well described.

Multidisciplinary surgical treatment approach for dermatofibrosarcoma protuberans: an update.

Dermatofibrosarcoma protuberans (DFSP) is a cutaneous sarcoma that has remained a challenge for oncologic and reconstructive surgeons due to a high rate of local recurrence. The objective of this study is to investigate the oncologic and reconstructive benefits of employing a multidisciplinary two-step approach to the treatment of DFSP. A retrospective review was conducted using a prospectively collected database of all patients who underwent resection and reconstruction of large DFSPs by a multidisciplinary team, including a Mohs micrographic surgeon, surgical oncologist, dermatopathologist, and plastic and reconstructive surgeon, at one academic institution from 1998-2018.

Performance of a 31-gene expression profile test in cutaneous melanomas of the head and neck.

Background: We report the performance of a gene expression profile test to classify the recurrence risk of cutaneous melanoma tumors of the head and neck as low-risk Class 1 or high-risk Class 2.

Methods: Of note, 157 primary head and neck cutaneous melanoma tumors were identified. Survival analyses were performed using Kaplan-Meier and Cox methods.

Guidance of sentinel lymph node biopsy decisions in patients with T1-T2 melanoma using gene expression profiling.

Aim: Can gene expression profiling be used to identify patients with T1-T2 melanoma at low risk for sentinel lymph node (SLN) positivity?

Patients & Methods: Bioinformatics modeling determined a population in which a 31-gene expression profile test predicted <5% SLN positivity. Multicenter, prospectively-tested (n = 1421) and retrospective (n = 690) cohorts were used for validation and outcomes, respectively.

Results: Patients 55-64 years and ≥65 years with a class 1A (low-risk) profile had SLN positivity rates of 4.

Follow-up of the melanoma patient.

Follow-up of the melanoma patient involves many different methods of surveillance. Specific guidelines for modalities and frequency are flexible and largely open to physician preference. Patient education and self-examination are generally viewed as crucial and cost-effective for recurrence detection.

National practice patterns of completion lymph node dissection for sentinel node-positive melanoma.

Background And Objectives: Close observation may be an appropriate alternative to completion lymph node dissection (CLND) for selected patient populations, especially those with minimal tumor burden in the sentinel lymph node (SLN). In this study, we examined the practice patterns of CLND utilization.

Methods: Using the National Cancer Database, we examined CLND utilization in SLN-positive patients diagnosed with clinically node-negative Stage III melanoma from 2012 to 2015.

Soft Tissue Sarcoma, Version 2.2018, NCCN Clinical Practice Guidelines in Oncology.

Soft tissue sarcomas (STS) are rare solid tumors of mesenchymal cell origin that display a heterogenous mix of clinical and pathologic characteristics. STS can develop from fat, muscle, nerves, blood vessels, and other connective tissues. The evaluation and treatment of patients with STS requires a multidisciplinary team with demonstrated expertise in the management of these tumors.

Performance of a prognostic 31-gene expression profile in an independent cohort of 523 cutaneous melanoma patients.

Background: The heterogeneous behavior of patients with melanoma makes prognostication challenging. To address this, a gene expression profile (GEP) test to predict metastatic risk was previously developed. This study evaluates the GEP's prognostic accuracy in an independent cohort of cutaneous melanoma patients.

Completion Dissection or Observation for Sentinel-Node Metastasis in Melanoma.

Background: Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.

Safety and Feasibility of Minimally Invasive Inguinal Lymph Node Dissection in Patients With Melanoma (SAFE-MILND): Report of a Prospective Multi-institutional Trial.

Background: Minimally invasive inguinal lymph node dissection (MILND) is a novel approach to inguinal lymphadenectomy. SAFE-MILND (NCT01500304) is a multicenter, phase I/II clinical trial evaluating the safety and feasibility of MILND for patients with melanoma in a group of surgeons newly adopting the procedure.

Methods: Twelve melanoma surgeons from 10 institutions without any previous MILND experience, enrolled patients into a prospective study after completing specialized training including didactic lectures, participating in a hands-on cadaveric laboratory, and being provided an instructional DVD of the procedure.
