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 [...]
Outcomes after definitive treatment for head and neck angiosarcoma.
Abstract Introduction: Head and neck angiosarcoma (HN-AS) is a rare and aggressive, representing <1% of all head and neck malignancies. It is characterized by a high rate of local recurrence and poor 5-year survival (10-54%). Australian data in this rare disease is lacking. We aim review the clinical outcomes of HN-AS from two high volume head and neck cancer units in Australia. Methods: Retrospective chart review. Results: A total 26 patients were identified, consist of predominantly male patients (81%) with a mean age of 77 year old. Most of the HN-AS arises from the scalp (62%). The 5-year overall survival (OS) and [...]
Complex melanoma of the scalp: Diagnosis and management aided by confocal microscopy.
Abstract Melanomas of lentigo maligna subtype are a steadily growing problem and frequently represent a clinical challenge. A case is reported of a complex melanoma of the scalp illustrating the critical role of confocal microscopy for optimal diagnosis and management. Read Full Paper

Histological regression in melanoma: impact on sentinel lymph node status and survival.
Abstract Regression in melanoma is an immunological phenomenon that results in partial or complete replacement of the tumor with variably vascular fibrous tissue, often accompanied by pigment-laden macrophages and chronic inflammation. In some cases, tumor-infiltrating lymphocytes (TILs) may represent the earliest phase of this process. The prognostic significance of regression has long been a matter of debate, with inconsistent findings reported in the literature to date. This study sought to determine whether regression in primary cutaneous melanomas predicted sentinel lymph node (SLN) status and survival outcomes in a large cohort of patients managed at a single centre. Clinical and [...]
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 [...]
Validation of the American Joint Committee on Cancer Staging in Squamous Cell Carcinoma of the Vermilion Lip
Abstract Background: The vermilion lip is a unique anatomical junction between cutaneous and mucosal surfaces. Squamous cell carcinoma (SCC) of the vermilion lip (vlSCC) was previously classified as oral SCC (oSCC) under the American Joint Committee on Cancer (AJCC) 7th edition (AJCC7), but has been recategorized as a cutaneous SCC of the head and neck (HNcSCC) in the AJCC 8th edition (AJCC8). We investigated the locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) for the various pathological T categories and disease stages of vlSCC as per AJCC8. Methods: We performed a retrospective cohort study of 297 patients diagnosed [...]
