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.

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…

Lipid rafts regulate the lamellipodia formation of melanoma A375 cells via actin cytoskeleton-mediated recruitment of β1 and β3 integrin.
Oncol Lett. 2018 Nov;16(5):6540-6546
Authors: Bi J, Wang R, Zeng X
Abstract
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…

AbstractAlthough nivolumab has been regarded as a standard agent for patients with previously treated advanced renal cell carcinoma (RCC), a significant proportion of these patients fail to achieve a response to nivolumab. In recent years, several studies have reported the favorable therapeutic impact of combined therapy with immune checkpoint inhibitors and radiotherapy on a wide variety of advanced malignant tumors, such as melanoma and lung cancer; however, the significance of this combined treatment for advanced RCC patients has not been well characterized. Here, we report two patients with metastatic RCC showing a mar…

Me-too deja vu
I read the report of a phase 3 RCT of a “new” breast cancer drug but I had the feeling that I had already read this before. Later I realized that this was indeed a new trial of a new drug, but that I had read a very similar report of a very similar drug with very similar results and conclusions. This new drug is a PARP inhibitor called talazoparib and the deja vu was related to another PARP inhibitor drug called olaparib tested in the same patient population of advanced breast cancer patients with a BRCA mutation. The control arms were the same: physician …

ConclusionsThe use of F5/35 ‐ZD55‐IL‐24 in conjunction with TMZ is a promising approach for anti‐melanoma therapy.Our results indicated that F5/35 ‐ZD55‐IL‐24 in combination with TMZ produced additive or synergistic antitumor effect and pro‐apoptotic effect in melanoma cells highly expressed CD46. The combination of F5/35‐ZD55‐IL‐24 and TMZ significantly inhibited the growth of melanoma in vivo. We also found the antitumor effect of F5/35‐ZD55‐IL‐24 was superior to ZD55‐IL‐24, the combination of F5/35‐ZD55‐IL‐24 and TMZ had a more significant antitumor effect than ZD55‐IL‐24 combining with TMZ.
