Objective To investigate the current status of parenting concerns in young and middle⁃aged patients with metastatic thyroid cancer, and to analyze its influencing factors. Methods A total of 227 young and middle⁃aged patients with metastatic thyroid cancer were selected as the research subjects. Investigation was performed by using the general information questionnaire, Parenting Concerns Questionnaire (PCQ), Fear of Progression Questionnaire Short Form (FoP⁃Q⁃SF), Comprehensive Scores for Financial Toxicity Based on the Patient⁃Reported Outcome Measures (COST⁃PROM) scale, and Family Adaptation, Partnership, Growth, Affection, Resolve Index (APGAR) scale. Results The total PCQ score of young and middle⁃aged patients with metastatic thyroid cancer was 37.88±10.94. There was statistically significant differences in PCQ total score between patients with different genders, educational levels, marital statuses, number of minor children, and conditions of concomitant chronic disease (P<0.05). The total PCQ score of young and middle⁃aged patients with metastatic thyroid cancer positively correlated with the total FoP⁃Q⁃SF score while negatively correlating with the total COST⁃PROM scale score and total APGAR scale score (P<0.05). Gender, number of minor children, level of fear of disease progression, financial toxicity level, and family function were the influencing factors for parenting concerns in young and middle⁃aged patients with metastatic thyroid cancer (P<0.05). Conclusion The parenting concerns of young and middle⁃aged patients with metastatic thyroid cancer are at a moderate level, with gender, number of minor children, level of fear of disease progression, financial toxicity level, and family function being influencing factors.
