Adjuvant radiotherapy after salvage surgery for melanoma recurrence in a node field following a previous lymph node dissection.
Abstract Background and objectives: Adjuvant radiotherapy (RT) can be given to melanoma patients following salvage surgery for node field recurrence after a previous regional node dissection, but the value of this treatment strategy is poorly documented. This study evaluated long-term node field control and survival of patients treated in this way in an era before effective adjuvant systemic therapy became available. Methods: Data for 76 patients treated between 1990 and 2011 were extracted from an institutional database. Baseline patient characteristics, treatment details and oncological outcomes were analysed. Results: Adjuvant RT with conventional fractionation (median dose 48 Gy in 20 [...]
Longitudinal trajectory of quality of life for patients with melanoma brain metastases: A secondary analysis from a whole brain radiotherapy randomized clinical trial.
Abstract Purpose: Brain metastases are common in patients with advanced melanoma. This study describes 12-month quality of life (QoL) trajectories following local management of 1–3 melanoma brain metastases. Methods: This study assessed QoL data collected during a multi-center, prospective, open-label, phase III randomized controlled trial comparing the efficacy of adjuvant whole brain radiotherapy (WBRT) with observation after local treatment of 1–3 melanoma brain metastases. Patients completed the European Organization for Research and Treatment of Cancer Quality of Life Core (QLQ-C30) and Brain Tumour (BN-20) questionnaires at baseline and every 2 months, for 12 months. Using growth mixture modelling, QoL trajectories were identified for [...]
Efficacy and toxicity of adjuvant radiotherapy in recurrent melanoma after adjuvant immunotherapy.
Abstract Background: In patients with stage III melanoma, despite surgical resection and adjuvant systemic therapy, locoregional recurrences still occur. The randomized, phase III Trans-Tasman Radiation Oncology Group (TROG) 02.01 trial demonstrated that adjuvant radiotherapy (RT) after complete lymphadenectomy (CLND) halves the incidence of melanoma recurrence within local nodal basins without improving overall survival or quality of life. However, the study was conducted prior to the current era of adjuvant systemic therapies and when CLND was the standard approach for microscopic nodal disease. As such, there is currently no data on the role of adjuvant RT in patients with melanoma [...]
Benchmarking Survival Outcomes Following Surgical Management of pT3 and pT4 Cutaneous Squamous Cell Carcinoma of the Head and Neck.
Abstract Background: pT3/4 head and neck cutaneous squamous cell carcinomas (HNcSCCs) are associated with poor outcomes, including local recurrence, metastasis and death. Whilst surgery remains the standard treatment for advanced HNcSCC, novel systemic therapies, such as immunotherapy, are being used earlier in the treatment paradigm. It is imperative that the clinical outcomes of surgery are clearly described so that conventional and emerging treatment modalities can be better integrated and sequenced in the management of pT3/4 HNcSCC. Methods: Patients with confirmed pT3/4 HNcSCC undergoing curative surgical resection between 2014-2020 were identified retrospectively from a prospectively maintained research database. The primary outcomes of [...]

Risk of radiation necrosis after stereotactic radiosurgery for melanoma brain metastasis by anatomical location.
Abstract Purpose: In this retrospective study, we have explored the anatomical factors that lead to the development of radiation necrosis (RN) in the setting of stereotactic radiosurgery (SRS) for melanoma brain metastases (MBM). Methods: Between 2014 and 2018, 137 patients underwent SRS for 311 MBM. Lesions were assessed according to anatomical zones: zone 1-peripheral grey-white matter junction and cortical mantle, zone 2-deep white matter, including tumours located at base of sulci, zone 3-tumours adjacent to ependymal lining or in deep locations such as brainstem, basal ganglia and thalamus. Other anatomical factors including lobes, medial-peripheral, supra or infratentorial locations were also recorded. [...]
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 [...]
