Experiences of Korean patients with thyroid cancer receiving radioactive iodine therapy after total thyroidectomy

South Korea has a high incidence of thyroid cancer. This study aimed to describe and understand the nature of the experience of Korean patients with thyroid cancer undergoing radioactive iodine treatment after total thyroidectomy through an in-depth investigation of their experience.

Individual interviews using open questions were conducted with 22 participants living in South Korea. All were audio-recorded and transcribed verbatim. This study used the phenomenological analysis method proposed by Colaizzi to determine the essential subjects verified according to the four reliability criteria proposed by Guba and Lincoln.

Three categories, 6 theme clusters, and 13 themes emerged from the study. The three categories identified were "broken life," "solitude in a crowd," and "positive changes in values." The six theme clusters were "anxiety about death," "an imperfect being," "feeling social isolation," "struggling alone," "an active attitude toward life," and "life support." The themes that emerged the most were related to physical and psychological difficulties. Of the 13 themes, four themes were related to family-oriented values and culture.

This study suggests that nursing interventions are required to reduce the physical and psychological symptoms of Korean patients with thyroid cancer. It is necessary to build a support system with the patient's family members to consider family-oriented values and culture.
