Melanoma and breast cancer (BC) patients face a high risk of recurrence and disease progression after curative surgery and/or therapeutic treatment. Monitoring for minimal residual disease (MRD) during a disease-free follow-up period would greatly improve patient outcomes through earlier detection of relapse or treatment resistance. However, MRD monitoring in solid tumors such as melanoma and BC are not well established. Here, we discuss the clinical applications of MRD monitoring in melanoma and BC patients and highlight the current approaches for detecting MRD in the…

Supermicrosurgical lymphaticovenular anastomosis may be efficient for the treatment of postoperative breast lymphedema, even in male patients.

Skin cancer remains the most common cancer in the United States, affecting approximately 20% of Americans during their lifetime. Despite major advances in care delivery, including targeted drug therapies and immunotherapy, the primary treatment for early nonmelanoma skin cancer (NMSC) and melanoma continues to be careful surgical extirpation with clear margins, along with meticulous reconstruction that optimally addresses functional and aesthetic deficits.

Skin cancer represents a broad classification of malignancies, which can be further refined by histology, including basal cell carcinoma, squamous cell carcinoma and melanoma. As these three cancers are distinct entities, we review each one separately, with a focus on their epidemiology, etiology including relevant genomic data, and the current evidence-based recommendations for adjuvant and neoadjuvant therapy. We also discuss future directions and opportunities for continued therapeutic advances.

Radiotherapy plays a role in the definitive or adjuvant management of early and late stage skin cancers including nonmelanoma basal cell carcinoma and cutaneous squamous cell carcinoma, melanoma, and Merkel cell carcinoma. The role of radiotherapy in skin cancers of the head and neck is reviewed including early and advanced-stage nonmelanoma skin cancers, melanoma, and Merkel cell carcinoma. In particular, the indications, oncologic outcomes, and technical aspects of radiotherapy for these diseases are discussed.

Sentinel lymph node biopsy uses the concept of selective lymphatic drainage and the lymphatic microvasculature to identify first-echelon nodes draining a given malignancy. Although initially considered difficult and unreliable in the head and neck, experience with the technique has improved and evolved significantly over the last 3 decades. It is now recognized to be accurate and reliable for regional nodal staging and detection of occult nodal metastasis in the head and neck. Although initially described for nodal staging of melanoma, the usefulness of sentinel lymph node biopsy continues to expand and is now extended to …

Melanoma is a potentially aggressive skin cancer with a steadily rising incidence. Most melanomas are diagnosed at an early stage and associated with an excellent prognosis when treated appropriately. Primary treatment for melanoma is surgical. Wider surgical margins and a variety of techniques for comprehensive histologic margin assessment may be considered for lentigo maligna type melanoma on the head and neck, due to characteristic broad subclinical extension. For invasive melanoma, sentinel lymph node biopsy may be indicated for staging, and to guide further management and follow-up. Appropriate treatment guidelines fo…

Metastatic melanoma can be highly refractory to conventional radiotherapy and chemotherapy but combinatorial-targeted therapeutics are showing greater promise on improving treatment efficacy. Previous studies have shown that knockdown of Forkhead box M1 (FOXM1) can sensitize various tumor types to radiation-induced cell death. The effect of combining radiation with a small molecule FOXM1 inhibitor, Siomycin A, on growth, death and migration of a metastatic melanoma cell line (SK-MEL-28) that overexpresses this pleiotropic cell cycle regulator was inv…

Lipid rafts regulate the lamellipodia formation of melanoma A375 cells via actin cytoskeleton-mediated recruitment of β1 and β3 integrin.

Lipid rafts, distinct liquid-ordered plasma membrane microdomains, have been shown to regulate tumor cell migration by internalizing and recycling cell-surface proteins. The present study reports that lipid rafts are a prerequisite for lamellipodia formation, which is the first step in the processes of tumor cell migration. The results from the wound-healing assay and immunostaining…
