Determinants of Prognosis in Head and Neck Cutaneous Squamous Cell Carcinoma With Nodal Metastases.

Importance: The eighth edition tumor, node, metastasis (TNM) staging for head and neck cutaneous squamous cell carcinoma (HNcSCC) is a poor predictor of survival in patients with lymph node metastases, possibly due to the inclusion of extranodal extension (ENE).

Objective: To identify the key determinants of prognosis in patients with nodal metastatic HNcSCC and analyze the association of ENE with TNM stage and investigate for prognostic heterogeneity in ENE-positive disease.

Design, Setting, And Participants: This retrospective, multicenter cohort study was conducted at 4 Australian tertiary referral centers using prospectively collected data in patients treated between 1980 and 2017 with a median (IQR) follow-up of 3.

Predictors of distant metastatic recurrence in head and neck cutaneous squamous cell carcinoma with lymph node metastases treated with curative intent: A multicenter study.

Background: We aimed to identify predictors of distant metastatic recurrence (DMR) in patients with head and neck cutaneous squamous cell carcinoma (HNcSCC) with nodal metastases treated with curative intent.

Methods: Predictors of DMR were identified using Cox regression in a multicenter study of 1151 patients.

Results: The 5-year risk of DMR was 9.

Merkel-cell carcinoma: ESMO-EURACAN Clinical Practice Guideline for diagnosis, treatment and follow-up.

• This ESMO Clinical Practice Guideline provides key recommendations for managing Merkel-cell carcinoma (MCC). • Recommendations are based on available scientific data and the multidisciplinary group of experts’ collective opinion. • The guideline covers clinical and pathological diagnosis, staging and risk assessment, treatment and follow-up.

Acute Diabetes-Related Complications in Patients Receiving Chemoradiotherapy for Head and Neck Cancer.

Unlabelled: Patients with cancer and diabetes face unique challenges. Limited data are available on diabetes management in patients undergoing concurrent chemoradiotherapy (CCRT), a curative intent anticancer therapy commonly associated with glucocorticoid administration, weight fluctuations and enteral feeds. This retrospective case-control study examined the real-world incidence of acute diabetes-related complications in patients with head and neck cancer receiving CCRT, along with the impact of diabetes on CCRT tolerance and outcomes.

Improving accuracy in nodal staging of oral cancer: Proposal of a new system.

Background: Despite introduction of extranodal extension (ENE) into the AJCC 8th edition of oral cancer staging, previous criticisms persist, such as limited discrimination between sub-stages and doubtful prognostic value of contralateral nodal disease. The purpose of this study was to compare our novel nodal staging system, based on the number of positive nodes and ENE, to the AJCC staging system in surgically treated patients.

Methods: Retrospective analysis of 4710 patients with oral squamous cell carcinoma (OSCC) treated with surgery±adjuvant therapy in 8 institutions in Australia, North America and Asia.
