Quality assurance of radiotherapy in the ongoing EORTC 1219-DAHANCA-29 trial for HPV/p16 negative squamous cell carcinoma of the head and neck: Results of the benchmark case procedure.

Background And Purpose: The phase III EORTC 1219-DAHANCA 29 intergroup trial evaluates the influence of nimorazole in patients with locally advanced head and neck cancer when treated with accelerated radiotherapy (RT) in combination with chemotherapy. This article describes the results of the RT Benchmark Case (BC) performed before patient inclusion.

Materials And Methods: The participating centers were asked to perform a 2-step BC, consisting of (1) a delineation and (2) a planning exercise according to the protocol guidelines.

Are anti-vitamin K drugs contraindicated with cetuximab during head-and-neck cancer concomitant radiotherapy?

Two cases of severe skin reactions to cetuximab and concomitant radiation therapy are reported in patients treated for locally advanced head-and-neck squamous cell carcinoma and concurrently treated with an antivitamin K drug for cardiovascular diseases. The role of vitamin K in the epidermal growth factor/epidermal growth factor receptor pathway is discussed. A plea for a specific registry is entered.

Leiomyosarcoma of the inferior nasal concha: a case report and literature review.

Leiomyosarcomas (LMSs) of the sinonasal tracts are rarely reported. We present a case of an LMS of the left inferior nasal concha, and discuss the management options with review of the literature. A 72-year-old female patient presented with epistaxis.

Adaptive functional image-guided IMRT in pharyngo-laryngeal squamous cell carcinoma: is the gain in dose distribution worth the effort?

Background And Purpose: The planning process in radiotherapy (RT) typically involves the acquisition of a unique set of CT images - and eventually of functional images - which is used for delineation of target volumes (TV) and organs at risk (OAR) and for dose calculation. Restricting the delineation and dose calculation solely on pre-treatment images is an oversimplification as it is only a snapshot of the patient's anatomy. The objectives of the present study were (1) to assess the consequences of anatomic modification in dose distribution for both TVs and OARs; (2) to assess the potential benefit of adaptive strategies using Helical Tomotherapy (HT); and (3) to compare CT-based and FDG-PET-based adaptive planning strategies.

Recommendations for a lifestyle which could prevent breast cancer and its relapse: physical activity and dietetic aspects.

External factors such as eating habits and physical activity have an important impact on breast cancer risk. This paper reviews the literature on the relationship between breast cancer and lifestyle. It aims to produce recommendations regarding physical activity and dietary intake for clinical practice.
