Experimental studies have implicated the wild type p53 in cellular response to radiation. Whether altered p53 function can lead to changes in clinical radiocurability remains an area of ongoing study. This study was performed to investigate whether any correlation between change of p53 and outcome of curative radiation therapy in patients with head and neck cancers.(omitted)

Purpose: Deep inspiration breath hold (DIBH) is a well-established technique that enables efficient cardiac sparing in patients with left-sided breast cancer. The aim of the current study was to determine if DIBH is effective for reducing radiation exposure of of liver and other organs at risk in right breast radiotherapy (RT). Materials and Methods: Twenty patients with right-sided breast cancer were enrolled in this study. Three-dimensional conformal RT plans were generated for each patient, with two different computed tomography scans of free breathing (FB) and DIBH. Nodes were contoured according to the Radiation Therapy Oncology Group contouring guidelines. Dose-volume histograms for the target volume coverage and organs at risk were evaluated and analyzed. Results: DIBH plans showed significant reduction in mean liver dose (5.59 ± 2.07 Gy vs. 2.54 ± 1.40 Gy; p = 0.0003), V_20Gy (148.38 ± 73.05 vs. 64.19 ± 51.07 mL; p = 0.0003) and V_10Gy (195.34 ± 93.57 vs. 89.81 ± 57.28 mL; p = 0.0003) volumes compared with FB plans. Right lung doses were also significantly reduced in DIBH plans. Heart and left lung doses showed small but statistically significant improvement with application of the DIBH technique. Conclusion: We report that the use of DIBH for right-sided breast cancer significantly reduces the radiation doses to the liver, lungs, and heart.

As the radiotherapy technique development, the needs for using of medical electronic chart in the department of radiation oncology is growing. However, the complexity of affairs of radiation oncology make it difficult to develop a electronic medical chart. In this study, we introduce the electronic medical chart developed by domestic hospital. The function and example of electronic medical chart designed as radiation treatment progress was showed and the future study was presented.

Purpose: The purposes of this study were to identify job definition, duties and tasks of Korean oncology Advanced Practice Nurses (APNs) and assess frequency, importance, and difficulty for each of duty and task using the DACUM method. Methods: The DACUM committee was organized with nine oncology APNs. The committee documented the job definition, duties and tasks based on their daily job descriptions. Validity of the elicited duties and tasks was tested by a study team and 6 oncology APNs. Data were collected using a questionnaire survey from 53 oncology APNs. Results: The job description of oncology APNs was identified 12 duties and 66 tasks. Among the twelve duties, 'education for patients/families' was the most frequently performed and was the most important duty. 'Case management' was the most difficult duty. Among 66 tasks, 'providing education for patients/families' was most frequently performed. 'Providing education for patients/families' and 'assessing patient condition comprehensively' were the most important tasks. 'Implementation research' as the principal investigator was perceived as the most difficult task. Conclusion: In this study, Korean oncology APNs' job performances were identified and analyzed. It is recommended that job description for oncology APNs needs to be standardized and reshaped in advanced way in future.
