Predicting Recurrence-Free and Overall Survival for Patients With Stage II Melanoma: The MIA Calculator.
Abstract Purpose: Improvements in recurrence-free survival (RFS) were demonstrated in two recent randomized trials for patients with sentinel node (SN)-negative stage IIB or IIC melanoma receiving adjuvant systemic therapy (pembrolizumab/nivolumab). However, adverse events also occurred. Accurate individualized prognostic estimates of RFS and overall survival (OS) would allow patients to more accurately weigh the risks and benefits of adjuvant therapy. Since the current American Joint Committee on Cancer eighth edition (AJCC-8) melanoma staging system focuses on melanoma-specific survival, we developed a multivariable risk prediction calculator that provides estimates of 5- and 10-year RFS and OS for these patients. Methods: Data were extracted [...]
Population-Based Validation of the MIA and MSKCC Tools for Predicting Sentinel Lymph Node Status.
Abstract Importance: Patients with melanoma are selected for sentinel lymph node biopsy (SLNB) based on their risk of a positive SLN. To improve selection, the Memorial Sloan Kettering Cancer Center (MSKCC) and Melanoma Institute Australia (MIA) developed predictive models, but the utility of these models remains to be tested. Objective: To determine the clinical utility of the MIA and MSKCC models. Design, setting, and participants: This was a population-based comparative effectiveness research study including 10 089 consecutive patients with cutaneous melanoma undergoing SLNB from the Swedish Melanoma Registry from January 2007 to December 2021. Data were analyzed from May to August 2023. [...]

Role of Concurrent Ultrasound Surveillance of Sentinel Node-Positive Node Fields in Melanoma Patients Having Routine Cross-Sectional Imaging.
Abstract Purpose: In sentinel node-positive (SN+ve) melanoma patients, active surveillance with regular ultrasound examination of the node field has become standard, rather than completion lymph node dissection (CLND). A proportion of these patients now receive adjuvant systemic therapy and have routine cross-sectional imaging (computed tomography [CT] or positron emission tomography [PET]/CT). The role of concurrent ultrasound (US) surveillance in these patients is unclear. The purpose of our study was to describe the modality of detection of nodal recurrence in SN+ve node fields. Methods: SN+ve melanoma patients who did not undergo CLND treated at a single institution from January 1, 2016 to [...]

Does preoperative imaging for scalp non-melanocytic skin cancer accurately predict invasion of the cranial vault? A systematic review and meta-analysis.
Abstract Purpose: This study aimed to determine the diagnostic accuracy of CT and MRI in the preoperative detection of bone involvement for non-melanoma skin cancers (NMSCs) located on the scalp. This study further aimed to evaluate the predictive value of these imaging modalities in determining the need for craniectomy and to identify gaps in the existing literature. Methods: Electronic searches of the MEDLINE, Embase, Cochrane and Google Scholar databases were performed for English language studies of any type. Studies reporting detection or exclusion of histopathologically confirmed bone involvement through preoperative imaging were identified according to PRISMA guidelines. Studies reporting dural involvement, [...]
Vasopressors improve outcomes in autologous free tissue transfer: A systematic review and meta-analysis
Abstract Background: Vasopressor use in patients undergoing autologous free tissue transfer is generally discouraged by surgeons perioperatively. This stems from concerns about the increased risk of flap failure with their use. The aim of this systematic review was to investigate the evidence and quantify any harm or benefits associated with vasopressor use. Methods: A systematic review of the literature was undertaken using OVID Medline to search 13 databases. The search strategy used Boolean operators, text word searches, truncation symbols, and adjacency searching. Terms such as "free flap," "free tissue graft," and "free tissue transfer" were used along with a list of [...]
Has the advent of modern adjuvant systemic therapy for melanoma rendered sentinel node biopsy unnecessary?
Abstract The prognostic value of sentinel node biopsy (SNB) is well established and SNB was therefore adopted as a requirement for pathological staging of melanomas>1 mm thick in the American Joint Committee on Cancer (AJCC) 8th edition. Consequently, a negative SNB status became an eligibility criterion for clinical trials of adjuvant systemic therapy in resected stage IIB/C melanoma. However, since the Keynote 716 trial demonstrated an improvement in relapse-free survival (RFS) in patients with Stage IIB/C melanoma, all of whom had SNB staging, some have argued that SNB is no longer required for patients with T3 and T4 primary [...]
Plain Language Summary – Development and validation of risk calculators for people with “thin” melanomas on their skin to predict the likelihood that their cancer will return.
Abstract What is this summary about?: This is a summary of an article describing the development of risk calculators for use in people who develop a type of melanoma on their skin called "thin" melanoma to predict the likelihood that their cancer will return. The article was originally published in the Journal of Clinical Oncology in 2021. How were the calculators developed?: Calculations were performed to predict the chance of people with thin melanomas surviving without their melanoma recurring. Three graphical prediction calculators (called nomograms) were developed, along with easy-to-use online calculators using the same underlying calculation methods. The [...]
Clinical Management of Melanocytic Tumours of Uncertain Malignant Potential (MelTUMPs), including Melanocytomas: A Systematic Review and Meta-Analysis.
Abstract Little guidance is currently available for managing patients with melanocytic tumours of uncertain or low malignant potential (MelTUMPs, including melanocytomas), in particular the optimal excision margins and whether to offer sentinel node biopsy (SNB). The objective of this review was to evaluate excision margins and the prognostic utility of SNB by systematic review of the literature and meta-analysis. PRISMA guidelines were followed. Medline, EMBASE and Cochrane databases were searched to October 2021 for studies of patients with MelTUMPs reporting excision margins and/or SNB-positivity. Meta-analysis was performed on the SNB-positivity rate using a random effects model, followed by sensitivity [...]
