Abstract

Head and neck cancer is the top ten death in Thailand and is challenging to treat by Intensity Modulated Radiation Therapy (IMRT). So the accuracy and precision for IMRT treatment in a patient with a tracheostomy who may cough during treatment are critical. Objectives: To compare image deviation from motion during IMRT treatment between on-board imaging radiograph and reference X-ray image in patients. Methods: A quasi-experimental research comparing image deviation from motion during IMRT treatment between on-board imaging radiograph (OBI) and reference X-ray image in a patient with tracheostomy. The sample was 95 head and neck cancer patients with tracheostomies who received radiation treatment in the Radiotherapy Department, Lopburi Cancer Hospital. The research tool was an on-board imaging device on the Linear accelerator machine series Clinic ix. The data record form includes regular patient information and image deviation from motion during treatment between on-board imaging radiograph and reference X-ray image. Data acquisition was recorded by the image deviation from motion during IMRT treatment between on-board imaging radiograph and reference X-ray image which is displayed on the monitor of portal imaging program. The data acquisition period was between 1st March 2020 and 31st October 2020. The data were analyzed using Wilcoxon Sign Rank Test statistics. Results: The results found that 69.5 percent of patients were male and aged between 40-60 years old.There were 81 percent and 87 percent had a cough and hard to breathe, so the image deviation value of the X-ray image missed align from the reference image in all axis with the P-value were 0.444, 0.705 and 0.423 in x, y, z-axis by order. Conclusions: Finally, the image deviation value of X-ray image in head and neck cancer patients with tracheostomies is not statistically different. So, the use of IMRT treatment technique is practical in patients with tracheostomies.
