Optimal sunscreen use, during a sun-holiday with a very high UV index, allows vitamin D synthesis without sunburn.

CONCLUSIONS: Sunscreens may be used to prevent sunburn yet allow vitamin D synthesis. A high UVA-PF sunscreen enables significantly higher vitamin D synthesis than a low UVA-PF sunscreen because the former, by default, transmits more UVB than the latter.

Abstract An accurate profiling of the genomic landscape is mandatory to establish the best clinical and therapeutic approach for patients with solid malignancies. Moreover, tumor cells constantly adapt to external pressures-i.e., systemic treatment-with the selection and expansion of resistant subclones and the emergence of heterogeneous overlapping genomic alterations of resistance. The current standard for molecular characterization in cancer is the performance of a tissue tumor biopsy at the time of diagnosis and, when possible, a re-biopsy at the time of progression. However, tissue biopsy is not always feasib...

We report an unprecedented case of squamous cell carcinoma (SCC) in the floor of mouth of a 23-year-old woman with XP. The patient was referred to the oncologist and, two months after surgical resection, underwent a single chemotherapy and radiotherapy session. However, she died 73 hours after undergoing her first chemotherapy session. Considering the unexpected outcome of this case, we also investigated possible exacerbated adverse effects of antineoplastic treatments (especially cisplatin-based chemotherapy) in XP patients, and discussed the main characteristics of the disease, especially cases with oral manifestations d...

This study investigates differences in the effects on cell growth of cetuximab and EGFR TKI AG1478 at the molecular level using oral squamous cell carcinoma (OSCC) cell lines. First, we found that there were EGFR-inhibitor-sensitive (EIS) and EGFR-inhibitor-resistant cell lines. The EIS cell lines expressed not only EGFR but also ErbB3, and both were clearly phosphorylated. The levels of phosphorylated ErbB3 were unaffected by cetuximab but were reduced by AG1478. EGFR ligand treatment increased the levels of phosphorylated EGFR but not phosphorylated ErbB3. Moreover, when EIS cell lines that were only capable of anchorage...

(Natural News) Prostate cancer is among the leading cancers in men in the U.S., second only to skin cancer. The American Cancer Society estimates around 174,650 new cases of – and 31,620 deaths from – prostate cancer each year, in its latest report. Fortunately, new evidence suggests that eating certain foods could play a role in starving – or even preventing – cancer....

Publication date: Available online 12 October 2019Source: British Journal of Oral and Maxillofacial SurgeryAuthor(s): S.N. Rogers, A. Swain, C. Carroll, D. LoweAbstractAfter their initial presentation of oral squamous cell carcinoma (SCC), patients have a lifelong risk of developing another new SCC of the head and neck. The aim of this study was to establish second primary rates, baseline characteristics (site, clinical or pathological stage, and smoking and alcohol history), timing, presentation, treatment, and outcomes. From the regional unit we analysed records of patients treated with curative intent for their first or...
