Feasibility and tolerability of breath-hold in liver stereotactic body radiotherapy with surface guided radiotherapy.

Purpose: Intrafractional motion constitutes a significant challenge in SBRT (Stereotactic Body Radiotherapy).The breath-hold (BH) technique is employed to mitigate tumor motion; however, ensuring reproducibility and consistency remains critically important. Surface tracking systems, integrated into the treatment process, facilitate motion tracking through three-dimensional camera technology.

Assessment of early and late dysphagia using videofluoroscopy and quality of life questionnaires in patients with head and neck cancer treated with radiation therapy.

Backgorund: The aim of this study was to evaluate dysphagia in patients with head and neck cancer (HNC) undergoing three-dimensional conformal radiation therapy using objective and subjective tools simultaneously and to associate the clinical correlates of dysphagia with dosimetric parameters.

Methods: Twenty patients were included in the study. The primary tumor and the involved lymph nodes (LN) were treated with 66-70 Gy, the uninvolved LN were treated with 46-50 Gy.

Evaluation of the efficacy of aprepitant on the prevention of chemotherapy-induced nausea and vomiting and quality of life with functional living index emesis.

Objective: Functional Living Index Emesis (FLIE) is developed to evaluate the relationship between emesis and it's effects on patient's daily life and is far more relevant to detect the effectiveness of antiemetic treatment compared with self-diary reports. In this study, the efficacy of oral neurokinin-1 antagonist aprepitant on the prevention of chemotherapy-induced nausea and vomiting and quality of life is evaluated with FLIE.

Study Design: Cross sectional study.
