Periorbital Microcystic Adnexal Carcinoma With Distant Metastases.

Purpose: Microcystic adnexal carcinoma (MAC) is a locally aggressive adnexal carcinoma of the head and neck, which has a high tendency for recurrence. MAC rarely has distant metastasis, with only one previously reported case originating from the periorbital region. We present a patient with periorbital MAC with distant metastasis and a review of all reported patients with metastatic disease.

Identifying the location of locoregional recurrences after definitive radiotherapy for head and neck cancer using metabolic parameters of baseline and mid-treatment 18F-FDG-PET scans.

Introduction: Tumour recurrences after treatment of head and neck squamous cell carcinoma (HNSCC) are more likely to originate from regions of high-baseline FDG-PET uptake. Mid-treatment functional imaging can potentially predict for higher risk of tumour recurrence. The aim of this study is to correlate the location of locoregional tumour recurrence with baseline FDG-PET metabolic volumes and mid-treatment FDG-PET metabolic volumes in patients with HNSCC following definitive radiotherapy.

Cutaneous squamous cell carcinoma metastatic to the axilla and groin: Outcomes and prognostic factors.

Purpose: This study examined the clinical outcomes and prognostic factors of patients with metastatic cutaneous SCC metastatic to the axilla and groin when managed with curative-intent lymphadenectomy and received (neo)adjuvant treatment.

Methods And Materials: We conducted a single institution retrospective review. Patients who had nodal disease without distant spread were 18 years or older with no non-cutaneous primary identified.

Phase I/II trial of concurrent extracranial palliative radiation therapy with Dabrafenib and Trametinib in metastatic BRAF V600E/K mutation-positive cutaneous Melanoma.

Background: Concurrent treatment with BRAF inhibitors and palliative radiation therapy (RT) could be associated with increased toxicity, especially skin toxicity. Current Eastern Cooperative Oncology Group (ECOG) consensus guideline recommend ceasing BRAF inhibitors during RT. There is a lack of data regarding concurrent RT with combined BRAF and MEK inhibitors.

Number of nodal metastases and prognosis in metastatic cutaneous squamous cell carcinoma of the head and neck.

Background: Existing prognostic systems for metastatic cutaneous squamous cell carcinoma of the head and neck (cSCCHN) do not discriminate between the number of involved nodes beyond single versus multiple. This study aimed to determine if the number of metastatic lymph nodes is an independent prognostic factor in metastatic cSCCHN and whether it provides additional prognostic information to the American Joint Committee on Cancer (AJCC) staging.

Methods: We retrospectively analysed 101 patients undergoing curative intent treatment for metastatic cSCCHN to parotid and/or neck nodes by surgery +/- radiotherapy at Liverpool Hospital, Sydney, Australia.
