What types of skin cancers are linked to these genes? Response: Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) collectively referred to as “keratinocyte cancers” are the commonest forms of cancers of the skin. Although these cancers are less aggressive than melanoma, due to their large numbers, they pose a significant burden to the healthcare expenditure. Also, these cancers are relatively understudied when compared with melanoma. Notably, BCC and SCC are not routinely reported in cancer registries. In Australia, Medicare data are used to estimate the incidence and costs associated with these cancers. Expenditure in Australia for the diagnosis, treatment and pathology, almost exceeds $700 million for both BCC and squamous cell carcinoma. In Unites States, the average annual cost for skin cancer including melanoma is approximately $8.1 billion. Previous research has led to identification of 29 BCC and 11 squamous cell carcinoma genetic risk variants and 7 of them overlap with both BCC and SCC risk. So, to strengthen the preventive efforts and to reveal new therapeutics, it is very timely and critical to explore more on the genetic susceptibility of these deadly cancers. We analysed ~48,000 cancer cases with ~630,000 skin cancer free controls from European ancestry population in Australia, UK and USA.

Response: Cutaneous squamous cell carcinoma (SCC) is a common skin cancer in people with fair skin. Vitamin A is a fat-soluble vitamin that is naturally present in many foods such as green leafy vegetables, fruits including cantaloupe, apricots, and mangos, and dairy products. We studied whether vitamin A intake is beneficial against SCC risk because there are few ways to prevent skin cancer.

MedicalResearch.com Interview with: [caption id="attachment_44374" align="alignleft" width="134"]Jeffrey Rapaport Dr. Rapaport[/caption] Dr. Jeffrey Rapaport MD, PA Emeritus head of Dermatology Teaneck's Holy Name Hospital. Dr. Rapaport discusess a case recently reported in JAMA: In 2016: A 97-year-old female patient was suffering from multiple squamous cell carcinomas varying from small to incredibly large in size on both of her legs. She was injected with the HPV vaccine commonly known as Gardasil, which is also used to treat warts and oral papilloma. She was first injected in her arm, and then after a period of six weeks, the vaccine was directly injected into her tumors. It was observed that this treatment eventually killed off almost all the tumors on her legs. According to recent press coverage, she is now looking forward to celebrating her 100th birthday in fall 2018. MedicalResearch.com: What is the background for this study?Is HPV thought be a trigger for some cutaneous squamous cell carcinomas? Response: The link between skin cancers and HPV vaccinations has normally been investigated in patients who have received organ transplants. Due to the immune-suppressant drugs these patients must take, it is incredibly common to find cases of skin cancer in patients who have undergone transplants. The relaxed immune system, which would normally eliminate cancers caused by the HPV virus, would open the floodgates for multiple skin tumors to emerge. In this case of the 97 year old, I would assume her immune system was healthy. There is, however, growing evidence that receiving multiple vaccines for the HPV virus is necessary even in patients with healthy immune systems. So, regardless of immune health, I believe we need to expand the frequency of the HPV vaccine, even beyond the current three-tiered system for women below 26 and men below 21.

Chen, MD/MHS Department of Otolaryngology- Head and Neck Surgery Stanford University Dr. Michelle Chen[/caption] Michelle M. Chen, MD/MHS Department of Otolaryngology- Head and Neck Surgery Stanford University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The benefit of post-operative radiotherapy (PORT) for patients with T1-T2 N1 oral cavity and oropharyngeal cancer without adverse pathologic features is unclear. Starting in 2014, the national guidelines no longer recommended consideration of post-operative radiotherapy for N1 oropharyngeal cancer patients, but left it as a consideration for N1 oral cavity cancer patients. We found that post-operative radiotherapy was associated with improved survival in both oral cavity and oropharyngeal cancers, particularly in patients younger than 70 years of age and those with T2 disease.
