Introduction Today, there is a growing interest in the use of hadrontherapy as an advanced radiotherapy technique. Hadrontherapy is considered a promising tool for cancer treatment, given its high radiobiological effectiveness and high accuracy of dose deposition due to the physical properties of hadrons. However, new radiation modalities of dose delivery and on-line beam monitoring play crucia...

Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...

Objectives Aggressive cancer therapy places patients at a greater risk for oral complications. Cancer patients suffer from oral toxic effects secondary to antineoplastic therapy (radiotherapy and chemotherapy). The aim of this review is management of the head and neck   cancer patients that specifically emphasizes the prevention and treatment of oral and   dental complications associated with c...

OBJECTIVES To assess the stage at cancer diagnosis and survival after cancer diagnosis among people served by secondary mental health services, compared with other local people. SETTING Using the anonymised linkage between a regional monopoly secondary mental health service provider in southeast London of four London boroughs, Croydon, Lambeth, Lewisham and Southwark, and a population-based c...

OBJECTIVE To investigate the incidence and aetiology of secondary leukaemia after childhood cancer in Britain. DESIGN Cohort study and a case-control study. SETTING Britain and population based National Register of Childhood Tumours. SUBJECTS Cohort of 16,422 one year survivors of childhood cancer diagnosed in Britain between 1962 and 1983, among whom 22 secondary leukaemias were observed...

To assess the severity of illness of oncology patients, it is necessary to distinguish patients with a single primary tumor from patients with metastatic disease occurring at a secondary location remote from the primary site. We developed a ranked list of cancer groupings and an algorithm that could distinguish patients with primary and metastatic cancer even if no specific code for secondary c...
