Background: Nodal metastasis from cutaneous squamous cell carcinoma (SCC) is poorly predicted clinically and is associated with a high mortality rate.
Methods: From 2010 to 2013, patients with high-risk cutaneous SCC were assessed with sentinel node biopsy (SNB) either at the time of primary cutaneous tumor resection or at secondary wide local excision.
Results: Of 57 patients, 8 (14%) had nodal metastasis. Significant predictors of metastasis are the number of high-risk factors (p = .008), perineural invasion (PNI; p = .05), and lymphovascular invasion (LVI; p = .05). During a mean of 19.4 months, 9 patients developed recurrence and 6 died of cutaneous SCC, indicating that over 1300 patients would be required for a randomized controlled trial with 80% power to detect a significant difference in disease-free survival.
Conclusion: Lymph node metastasis occurs in 14% of patients with high-risk cutaneous SCC. Larger studies will be required to identify which "high-risk" factors should be considered as an indication for surgical assessment of the nodal basin. © 2015 Wiley Periodicals, Inc.

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally invasive cutaneous sarcoma with a high propensity for recurrence, even following complete surgical excision. DFSP exhibits a low metastatic potential and is characterized by a distinctive honeycomb-like architecture composed of uniformly arranged spindle cells that frequently show CD34 immunostaining. Common surgical approaches include wide local excision (WLE), Mohs micrographic surgery (MMS), and, in severe cases, amputation.

Mitophagy, the selective degradation of mitochondria by autophagy, plays a crucial role in cancer progression and therapy response. This study aims to elucidate the role of mitophagy-related genes (MRGs) in cutaneous melanoma (CM) through single-cell RNA sequencing (scRNA-seq) and machine learning approaches, ultimately developing a predictive model for patient prognosis. The scRNA-seq data, bulk transcriptomic data, and clinical data of CM were obtained from publicly available databases.

Objective: Solid organ transplant (SOT) recipients carry a higher incidence of cutaneous squamous cell carcinoma (cSCC) with more aggressive features and worse outcomes compared to immunocompetent (IC) patients. The National Comprehensive Cancer Network advocates peripheral and deep en-face margin assessment such as Mohs micrographic surgery (MMS) for very-high-risk cSCC. We aim to assess the efficacy of MMS in the treatment of SOT immunosuppressed head and neck (HN) cSCC patients.

Sentinel Lymph Node Biopsy (SLNB) aims at identifying clinically occult nodal metastases. It is the standard staging procedure for patients with T1b to T4 primary cutaneous melanoma. Moreover, it is recommended whenever the risk of a positive SLNB is >5%, according to the National Comprehensive Cancer Network Melanoma guidelines.

Melanoma is one of the most malignant cancers, and the global incidence of cutaneous melanoma is increasing. While melanomas are highly prone to metastasize if diagnosed late, early detection and treatment significantly reduce the risk of mortality. Identifying patients at higher risk of metastasis, who might benefit from early adjuvant therapies, is particularly important, especially with the advent of new melanoma treatments.
