Efficacy and safety profile of vismodegib in a real-world setting cohort of patients with advanced basal cell carcinoma in Argentina.

Introduction And Objectives: Vismodegib (Erivedge ), a hedgehog pathway inhibitor, is approved to treat metastatic or locally advanced basal cell carcinoma (BCC) not suitable for surgery or radiotherapy. Our main objectives were to study the objective response rate (ORR) assessed by treating physicians and safety of vismodegib in a real-world practice setting in Argentina.

Material And Methods: This is a prospective cohort study in real-world practice.

Neoadjuvant Vismodegib and Mohs Micrographic Surgery for Locally Advanced Periocular Basal Cell Carcinoma.

Introduction: Vismodegib has shown a significant response rate in locally advanced periocular basal cell carcinoma. Long-term monotherapy is very difficult to accomplish due to primary or secondary resistance and side effects that limit the length of treatment. The use of Vismodegib as neoadjuvant followed by Mohs micrographic surgery is an option.

Cutaneous human papillomavirus genotypes in different kinds of skin lesions in Argentina.

Cutaneous human papillomaviruses (HPVs) comprise a large and highly heterogeneous virus group. Some of the cutaneous HPVs of the genus Beta have been suggested as a co-factor in the development of non-melanoma skin cancer (NMSC). The aim of this study was to determine cutaneous HPV prevalence and type-specific distribution in different kinds of skin lesions from Argentine patients visiting Dermatology Departments of three hospitals from Buenos Aires.

Expression of CD44s and CD44 splice variants in human melanoma.

The ability of tumor cells to adhere and detach from extracellular matrix and endothelial cells, is a crucial step in the metastatic process and may alter the clinical prognosis of some human tumors such as melanomas. CD44, the major cell surface receptor for hyaluronate, has been implicated in cell adhesion and in tumor progression. We studied the expression of standard CD44 molecule (CD44s) and its variants v3 and v6 in 57 human primary melanoma biopsies, without previous treatment.
