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 [...]

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 [...]
Unicentric Castleman’s disease imitating metastatic melanoma: A case report
Abstract Introduction and importance: This case report shows a unique case of Castleman's disease in the context of histopathological diagnosis of cutaneous melanoma where clinical and radiological features of Castleman's disease were masked by presumptive diagnosis of metastatic melanoma. The disease is part of a group of lymphoproliferative disorders with characteristic histopathological features that can occur in any lymph node in the body, characterised by slow growing painless masses which are asymptomatic until mass effect occurs. This case highlights the need for caution when considering management of lymphadenopathy with clinically/radiologically suspicious nodes. Presentation of case: A 65 year old man with [...]
Embedding electronic patient-reported outcome measures into routine care for patients with stage III MELanoma (ePROMs-MEL): protocol for a prospective, longitudinal, mixed-methods pilot study.
Abstract Introduction: The benefits of patient-reported feedback, using questionnaires that allow patients to report how they feel and function without any interpretation from healthcare professionals, are well established. However, patient-reported outcomes measures (PROMs) are not routinely collected in patients with melanoma in Australia. The aim of this study is to evaluate the feasibility and acceptability of implementing electronic PROMs (ePROMs) into routine care from the perspectives of patients with stage III melanoma and their treating clinical team. Methods and analysis: A minimum of 50 patients and 5 clinicians will be recruited to this prospective, longitudinal pilot study (ePROMs-MELanoma). The [...]
Time interval between diagnostic excision-biopsy of a primary melanoma and sentinel node biopsy: effects on the sentinel node positivity rate and survival outcomes
Abstract Introduction: The optimal time interval between diagnostic excision of a primary cutaneous melanoma and sentinel node (SN) biopsy is unknown. The current study sought to determine whether this interval influenced the SN-positivity rate, recurrence or survival. Methods: Data collected from 2004 to 2014 for a Dutch population-based cohort of patients with melanoma who underwent SN biopsy (SNB) within 100 days of initial diagnosis (n = 7660) and for a similarly specified cohort from a large Australian melanoma treatment centre (n = 3478) were analysed. Time to SNB was analysed continuously (in weeks) and categorically (per month). The effects of SNB [...]

Effect of the time interval between melanoma diagnosis and sentinel node biopsy on the size of metastatic tumour deposits in node-positive patients.
Abstract Introduction: This study sought to assess whether the interval between diagnostic excision-biopsy of a primary melanoma and definitive wide excision with sentinel node biopsy (SNB) influenced the size of SN metastatic deposits, which might have implications for management and prognosis. Methods: Data were collected for (i) a Dutch population-based cohort of patients treated between 2004 and 2014 who underwent SNB within 100 days of complete excision of their primary melanoma and who were SN-positive with known SN metastasis diameter (n = 1027) and (ii) a cohort from a large Australian melanoma treatment centre (n = 541) who presented in the [...]
Clinicopathological characteristics of new primary melanomas in patients receiving immune checkpoint inhibitor therapy for metastatic melanoma
Abstract Background: Immune checkpoint inhibitors have improved survival in advanced stage melanoma patients. Rates of new primary melanomas (NPM) in patients with prior melanoma have been reported to be as high as 12%. Little is currently known regarding the frequency or characteristics of NPMs occurring in melanoma patients treated with immune checkpoint inhibitors. Aim: To determine the frequency and describe clinicopathologic characteristics of NPMs diagnosed in patients during or after treatment with immune checkpoint inhibitors for metastatic melanoma. Methods: A retrospective analysis of prospectively collected data from the Melanoma Institute Australia and Westmead Hospital Dermatology databases. Clinicopathological data for the initial primary [...]
