Differential outcome of concurrent radiotherapy plus epidermal growth factor receptor inhibitors versus radiotherapy plus cisplatin in patients with human papillomavirus-related head and neck cancer.

Background: Human papillomavirus (HPV)-related head and neck cancer has been associated with an improved prognosis in patients treated with radiotherapy (RT) +/- chemotherapy (CT); however, RT combined with epidermal growth factor receptor (EGFR) inhibitors has not been fully studied in this group of patients.

Methods: Immunohistochemical expression of p16 and PCR of HPV16 DNA were retrospectively analyzed in tumor blocks from 108 stage III/IV head and neck cancer patients treated with RT+CT (56) or RT+EGFR inhibitors (52). Disease-free survival (DFS) and overall survival (OS) were analyzed by the Kaplan-Meier method.

[Autosomal dominant punctate palmoplantar keratoderma].

Hereditary punctate palmoplantar keratoderma or Buschke-Fisher-Brauer disease is a rare form of keratoderma that follows a pattern of autosomal dominant inheritance with variable penetrance. The age of onset is usually between 12 and 30 years of age. Clinically, it is characterized by the gradual appearance of multiple punctate hyperkeratotic papules, irregularly distributed on the palms and soles, as well as by its possible association with several diseases, primarily with malignant processes.
