Clinical significance of intra-thoracic and intra-abdominal sentinel lymph nodes detected on lymphoscintigraphy in truncal melanoma patients.

Abstract Background: Although most melanomas drain to the more common major lymph node basins (axilla, groin, neck), rarely they drain to deep SLN locations such as intra-abdominal and intra-thoracic (including intercostal and internal mammary) sites, which pose a higher surgical risk and complexity for procurement. Our study is aimed at determining the rate of positivity and likelihood of recurrence in these nodal sites to guide management decisions for patients with truncal melanomas which drain to these 'deep' SLN locations. Methods: Retrospective data collected between May 2008 and May 2022 including all patients with truncal melanomas who underwent lymphoscintigraphy resulting in the [...]

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 [...]

Modeling Methods in Craniofacial Virtual Surgical Planning.

Abstract Despite the widespread use of virtual surgical planning (VSP), few papers describe the modeling methods used to generate the digital simulations that underpin VSP. This paper aims to review the modeling methods that are currently available for use in VSP and the implications of their use in clinical practice. A literature review was undertaken of the two broad categories of modeling techniques; contour-based planning-namely mirroring from the contralateral side, templating from a normative database, and extrapolation from surrounding landmarks-and occlusal-based planning (OBP). The indications for each modeling method were discussed, including mandibular/maxillary reconstruction, pediatric craniofacial surgery, and orthognathic, [...]

Case report of a challenging medium-sized congenital melanocytic nevus (CMN): Highlighting a role for reflectance confocal microscopy (RCM) for evaluating changing CMN in children.

Abstract A 3.5-month-old boy presented with a changing medium-sized congenital melanocytic nevus on his leg. Due to atypical features on dermoscopy and reflectance confocal microscopy (RCM), an excision of the area of concern was performed. Histopathology showed many of the pathological features usually associated with a diagnosis of melanoma in situ in older patients, but due to the young age of the patient, absence of mitoses, and the degree of atypia, a diagnosis of a dysplastic compound nevus arising in a congenital compound (predominantly dermal) nevus was favored. In our case, RCM corresponded to histopathology helped target the area [...]

Re-defining the role of surgery in the management of patients with oligometastatic stage IV melanoma in the era of effective systemic therapies.

Abstract Although previously the mainstay of treatment, the role of surgery in the management of patients with oligometastatic stage IV melanoma has changed with the advent of effective systemic therapies (most notably immunotherapy). Contemporary treatment options for patients with asymptomatic solitary or oligo-metastases include upfront surgery followed by adjuvant immunotherapy or upfront immunotherapy with salvage surgery as required. For suspected solitary or oligo-metastases, surgery serves both diagnostic and therapeutic purposes. Advances in radiological technology allow metastases to be detected earlier and surgery to be less morbid. Surgical morbidities are generally more tolerable than serious immune-related adverse effects, but surgery [...]
