Throughout the past two decades the efforts to improve the efficacy of treatment for locally advanced head and neck squamous cell carcinoma (HNSCC) have led to increased use of multimodality approaches combining surgery, radiotherapy (RT), and chemotherapy (CT). Conventional RT, a standard approach for locoregionally advanced disease, was associated with unsatisfactory results, thereby, a greater understanding of radiobiology led to the development of two classes of altered radiation fractionation schedules incorporating hyperfractionation (HF) and acceleration in the management of advanced HNSCC. Randomized controlled trials and meta-analyses demonstrated that for patients with locally advanced HNSCC major improvements in locoregional control (LRC) at high level of evidence can be achieved by accelerated fractionation (AF) and HF. ⋯ CCRT is now a standard treatment approach for patients with locally advanced HNSCC. CCRT has been also shown to allow organ preservation in almost two thirds of patients without affecting survival. Recently, strong evidence for an improved outcome for high-risk resected patients has been shown by the use of adjuvant CCRT.

Talc remains a commonly used agent for pleurodesis malignant pleural effusion. Nevertheless, it is associated with a 3-9% incidence of pulmonary reactions ranging from simple pneumonitis to acute respiratory distress syndrome (ARDS). The underlying lung pathology and the size and rate of talc particle dissemination have been implicated as the cause of these complications. There seems to be an acknowledged lack of evidence regarding detailed very early intrathoracic talc particle migration. ⋯ Large-sized talc particles are deposited on both lungs very early after pleurodesis. At the same time inflammatory pulmonary changes appear bilaterally. Despite contradicting data in the literature, these findings should always be kept in mind when performing this procedure in high risk patients.

In this article we present the opinions of some eminent Roman physicians about cancer. We emphasize the points of view of Galen, famous Roman physician of Greek origin whose doctrines dominated medicine for more than 15 centuries. We then cite the opinions about cancer of some other outstanding physicians of that period like Celsus, Pliny, Leonidis of Alexandria, Aretaeus of Cappadocia, Soranus of Ephesus etc. We also quote some examples of cancer and we describe what those physicians thought of its pathogenesis, diagnosis and treatment.
