Abstract

Breast cancer ranks first in terms of the highest number of cancers in Indonesia and is one of the first contributors to cancer deaths. According to IARC, radiotherapy is one of the most important modalities in the treatment of breast cancer. Radiotherapy is a type of treatment that uses ionizing radiation to kill cancer cells without damaging surrounding healthy tissue. To obtain an even or homogeneous dose distribution on an uneven skin surface, a wedge is used so that the radiation given to the tumor area is truly optimal and the surrounding healthy tissue receives a minimum dose. This research was carried out by evaluating the Planning Target Volume (PTV) value based on ICRU-83 and dose distribution in Organs at Risk (OAR) based on QUANTEC standards at four different wedge angles, namely 15°, 30°, 45°, and 60°, used the 3D-CRT technique of tangential radiation with a dose of 50 Gy in 25 fractions on 5 left-sided breast cancer patients. The research results showed that the average Homogeneity Index (HI) values for the 15°, 30°, 45° and 60° wedges were 0.286, 0.346, 0.436 and 0.578, respectively. In the left and right lung dose distribution, the results obtained for the 15°, 30°, 45°, and 60° wedge were respectively 2231.4 and 116.2 cGy, 2257.8 and 114.6 cGy, 2141 and 100 cGy, and 2059.4 and 88.8 cGy. For the average dose distribution to the heart, the values obtained at the 15°, 30°, 45°, and 60° wedges were 2005.6 cGy, 2040.4 cGy, 1930.6 cGy, and 1844.4 cGy, respectively. where the average dose received by OAR is still below the limit allowed by QUANTEC. Using a wedge angle of 15° provides a homogeneous dose distribution for the PTV and a wedge angle of 60° provides the lowest dose distribution for the OAR.

Abstract

Mental disorders have different manifestations and symptoms but are generally characterized by some combination of disturbances of thought, perception, emotion, behavior, and impaired relationships with other people. Severe mental disorders, including schizophrenia, are prone to stigma. Good self-acceptance has a robust negative correlation with stigma. This study examines the effect of Islamic acceptance and commitment therapy (ACT) on self-acceptance in patients with mental disorders. The research method is quantitative with a semi-experimental pre-post-test. Respondents in this study were 31 patients with mental disorders who were selected using a purposive sampling technique that met the criteria of being Muslim, awareness, and understanding of patients with mental disorders experienced in the good category, namely being aware of the disease experienced. The measuring instrument used in this study consisted of a demographic questionnaire and an Unconditional Self-Acceptance Questionnaire (USAQ). Results showed that ACT with Islamic approach significantly increased self-acceptance in a patient with mental disorders (P<0.001). ACT can be used as an effective intervention to increase self-acceptance in a patient with mental disorders.
