Abstract |
|
|
| The primary goal of radiotherapy is to deliver a lethal dose of radiation to the tumor while minimizing exposure to surrounding healthy tissues. The study aims to assess the radiation dose to the eye lens during the treatment of head and neck using a linear accelerator in a center in Abuja. This study is a retrospective analysis aimed at assessing the radiation dose to the eye lens during the treatment of head and neck cancers using a linear accelerator. The medical records and dosimetric data of patients who underwent radiotherapy between January 2024 and June 2024 at the Radiotherapy department, National Hospital, Abuja, were collected and assessed. The result of the dose to the lens per fraction of patients who underwent head and neck cancer treatment ranges from 0.015 to 0.097 cGy. This range is below the recommended dose limits by the International Commission on Radiological Protection (ICRP) and the American Association of Physicists in Medicine (AAPM), which are 0.15 cGy and 0.10 cGy per fraction, respectively. The Annual Equivalent Dose (AEDE) for eye lenses ranges from 13.000 to 84.067 cGy. The result of Excess Lifetime Cancer Risk (ELCR) for the eye lens ranges from 0.000715 to 0.004624. The results show that the doses received by the eye lens are within the acceptable limits recommended by the International Commission on Radiological Protection (ICRP). However, the study also highlights the importance of careful treatment planning and optimization strategies to minimize the risk of radiation-induced cancer. |
