How I treat anal squamous cell carcinoma
No full text: Squamous cell carcinoma of the anus (SCCA) is a rising health issue, strongly related to other relevant medical conditions such as (HIV) and human papillomavirus (HPV) infection. Correct assessment of patients with SCCA requires a multidisciplinary evaluation and adequate follow-up. Accurate local and systemic staging, as well as risk evaluation, are essential to optimal treatment planning. Early stage tumours can be definitively treated with a combination of chemotherapy and radiotherapy, while salvage surgery is usually reserved for patients who develop local recurrence. Distant recurrence and de novo metastatic disease are associated with poorer prognosis and require palliative systemic chemotherapy, with different single agent and combination options available. Finally, recent discoveries on the carcinogenesis of SCCA have allowed the development of innovative treatment options, the most promising being immune checkpoint inhibitors. The limited systemic treatments for SCCA and low incidence of the disease, together with insufficient data from clinical research could explain the poor outcomes of these patients, which should therefore be managed in high volume centres and enrolled in clinical trials whenever possible. This article summarises the main strategies for treating patients with SCCA
Panitumumab: the evidence of its therapeutic potential in metastatic colorectal cancer care
No full textColorectal cancer is the fourth most common malignant disease. Of newly diagnosed patients, 40% have metastatic disease at diagnosis, and approximately 25% of patients with localized disease at diagnosis will ultimately develop metastatic disease. The benefits of systemic chemotherapy in the treatment of metastatic colorectal cancer over best supportive care have been established. Panitumumab (ABX-EGF) is the first fully human monoclonal antibody developed for use in colorectal cancer that targets the extracellular domains of epidermal growth factor receptor

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
