As interprofessional work in cancer treatment becomes increasingly important, medical technologists are required to play active roles as part of the team. The cancer center of our hospital organized a lecture meeting, "The 6th Lecture Meeting: Living Together," for cancer patients and their families, and a medical technologist presented a lecture entitled: "Cancer treatment and clinical examinations." According to the results of a questionnaire survey conducted following the meeting, most participants were able to understand the lecture and were satisfied with it. Based on the opinions expressed by meeting participants and the questionnaire results, medical technologists initiate the following services and activities: 1. They explain the results of white blood cell and neutrophil counts of patients on chemotherapy and/or radiation therapy; and 2. provide medical examinations and consultation at outpatient chemotherapy centers. We believe that these efforts will help improve cancer treatment and further contribute to interprofessional health care.
