The aims of this study were to clarify difficulties experienced by families facing the cessation of home-based care for terminal cancer patients, and to review the associated necessary nursing practices. We conducted semi-structured interviews with ten families. A qualitative research design was selected for this study, and the data was interpreted using content analysis techniques. The results were integrated into seven major categories: “unable to assess present symptoms for lack of understanding terminal cancer symptoms,” “feeling emotional pain during the patient’s aggravated condition,” “difficulties in coping with various patients’ physical symptoms: problems regarding inexperienced care,” “exhausted by living 24 hours a day with patient: lack of support, because of constraints from important people in the caregiver’s life,” and “difficulties faced by primary family caregivers in preparing a treatment environment.” Family caregivers were not able to prepare a treatment environment, because of a lack of understanding the symptoms of terminal cancer and an unwillingness to admit experiencing mental and physical burdens. The findings of this study suggested that the role of a nurse is to understand the family’s condition and values, provide required information in advance, and to adjust and prepare the treatment environment.

　　The Tsurumi Hospital introduced a state-of-the-art, multifunctional cancer radiation therapy system in April 2011. When a new building was completed. The cancer radiation therapy started in September of the same year. Our hospital as a cancer treatment hospital provides high-quality care, and can deliver radiation therapy of high performance and high precision in safety, and aims to be trusted by society and patients. In a cancer radiation therapy, it is important to work in teams made up of doctors, radiological technologists and nurses having a high degree of professionalism. In such circumstances radiological technologists have to play various roles and shoulder responsibility. For example, they have to take responsibility for dose distribution creation and calculation of monitor units according treatment plans, systems, positioning radiography, creating a fixture and immobilizer, verification of irradiation, setup of patient, quality assurance and quality control of related equipment for the radiotherapy system, explanation to the patient, medical safety and radiation maintenances etc. Since the introduction of the cancer radiation therapy system, radiological technologists have had to carry out work required for radiation therapy such as verification of creating specifications, determination of equipment, procedures based on the relevant laws and regulations, acceptance test, acquisition of clinical data, commissioning and verification of treatment dose. This paper describes the role and practice of radiological technologists to lead a cancer radiation therapy, based upon our experience.
