119 Cyclooxygenase-2 Inhibitor Use and Risk of Skin Cancer: Three Prospective Cohort Studies

Cyclooxygenase-2 (COX-2) inhibitor has been associated with lower risk of several cancers, but epidemiological studies on skin cancer risk have been limited and inconclusive. COX-2 inhibitor use and risk of basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), and melanoma were evaluated in three prospective cohorts - the Nurses ’ Health Study (NHS, 2000-2012), NHS II (2001-2011), and the Health Professionals Follow-up Study (HPFS, 2002-2012). COX-2 inhibitor use and skin cancer incidence were assessed using biennial questionnaires, with cSCC and melanoma cases verified by pathological records.

Non-melanoma skin cancer (NMSC) is the most common cancer worldwide. Australia has the highest incidence of skin cancer in the world, exceeding 2000 per 100  000 person-years and it is increasing [1]. In the USA, more than 3 million individuals are diagnosed with NMSC each year [2,3]. In the UK, during 2014–2016, about 147 000 new NMSC cases were diagnosed every year, more than 400 every day [4]. Data show that between 1976 and 1984, the overall inc idence of basal cell carcinoma (BCC) increased by 145% and of cutaneous squamous cell carcinoma (cSCC) by 263%.

Transplant recipients have a significantly higher risk of developing non-melanoma skin cancers compared with the general population and squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the most common post-transplant malignancies. Although in the general population BCC outnumbers SCC 4:1, in transplant patients this ratio is reversed and SCC is more common, with a 65- to 250-fold increased incidence. As patients in immunosuppressed states are living longer after transplants, the incidence of skin cancer in this population continues to increase.

Basosquamous carcinoma (BSC) is an aggressive skin neoplasm with features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). While genetic and molecular drivers of BCC and SCC development have been extensively characterized, BSC pathogenesis remains unclear, in particular regarding the reprogramming of tumor keratinocytes towards basaloid or squamatized phenotypes. Here, by analogy to pathway switching previously observed in BCC escaping Hedgehog (Hh) inhibition, we demonstrate loss of Hh signaling and MAPK pathway activation associated with squamatization of BSC.

Skin cancers are relatively rare in patients with skin of color; however, they are an important public health concern because of disparities in patient outcomes. Gaps in skin cancer knowledge exist because of lack of large-scale studies involving people of color, and limitations in data collection methods and skin classification paradigms. Additional research is needed to address questions regarding risk and reasons for disparate skin cancer outcomes in these patients. We summarize the clinical and epidemiologic features for basal cell carcinoma, squamous cell carcinoma, and melanoma and touch on some of their unique featu...

AbstractPurpose of ReviewThe aim of this work is to review the role of advanced non-invasive imaging, such as reflectance confocal microscopy (RCM) and optical coherence tomography (OCT), in malignant melanomas and non-melanoma skin cancers (NMSCs) using data coming from the most recent literature, with a particular highlight on the results of the European experience.Recent FindingsExamination with RCM and OCT increases the accuracy of diagnosis. The most recent diagnostic clues for melanoma and NMSCs are revised. In addition, the application of these techniques in presurgical margin definition and in monitoring the effica...

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer after basal cell carcinoma. While most cases are cured by excision, a substantial number of patients will develop local, regional, or distant recurrences, with the number of cSCC-related deaths approaching that from melanoma. Several clinical decisions, including the extent of surgical margins, the use of adjuvant radiation or chemotherapy, and sentinel lymph node biopsy/completion dissection, could be informed by a patient ’s relative risk of recurrence.

A previously uncharacterized pathway of vitamin D3 metabolism has been confirmed to operate in vivo, and this pathway begins with hydroxylation at C20 or C22. Resulting products, 20(OH)D3 and 22(OH)D3, have been detected in human serum and skin, and they undergo further hydroxylation to produce biologically active compounds that are noncalcemic at high pharmacologic doses. Many of these compounds have shown to inhibit growth of melanoma cells and stimulate keratinocytes differentiation. The purpose of this study was to investigate whether these novel vitamin D hydroxyderivatives will demonstrate therapeutic efficacy agains...

Vulvar malignancies represent a serious gynecologic health concern, especially given the increasing incidence over the past several decades. Squamous cell carcinoma and melanoma are common subtypes, although other neoplasms such as basal cell carcinoma and Paget ’s disease of the vulva may be seen. Many vulvar cancers are initially misdiagnosed as inflammatory conditions, delaying diagnosis and worsening prognosis. It is essential that dermatologists are familiar with characteristic findings for each malignancy in order to ensure appropriate diagnosis and management.
