Background/Aim:
Turner syndrome confers increased cancer susceptibility; however, large-scale epidemiological evidence is lacking. This study aimed to analyze the incidence and prevalence of various malignancies in patients with Turner syndrome over 20 years of age to inform screening strategies.
Patients And Methods:
We performed a retrospective cohort analysis of 11,502 patients with Turner syndrome from 2000 to 2020 utilizing the TriNetX research network database. The outcomes encompassed the incidence and prevalence of 20 cancers. Stratified analyses were used to evaluate variations in age, sex, and race.
Results:
Key findings demonstrated markedly elevated risks of breast (1.7%), colon (1.0%), renal (0.4%), gonadoblastoma (0.4%), and other cancers. Significant demographic variations were observed in the incidence of cancers, such as gonadoblastoma, renal, and colon cancer.
Conclusion:
This large real-world study offers novel insights into the spectrum of cancer risk across adulthood in Turner syndrome. Our findings elucidate Turner syndrome's complex cancer phenotype to inform clinical decision-making, prognostication, and tailored screening strategies to ultimately advance patient care.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
