Management outcomes of pediatric and adolescent papillary thyroid cancers with a brief review of literature

Background: Papillary carcinoma of thyroid (PTC) is a rare disease in children and adolescents and contributes to about 1.5%–3% of all pediatric malignancies. To date, no randomized trial has ever been performed in the pediatric population and management of these patients has been extrapolated from adult practice. Materials and Methods: Retrospective analysis of the patients treated for PTC in the age <21 years, between the years 1998–2013 at a tertiary cancer center from India. Results: Sixty-seven patients were treated in the above said period with a male:female ratio of 1:1.6 and a median age of 18 years. Fifty-two (77.6%) patients clinically presented as a thyroid swelling with or without nodal swelling while 13 (19.4%) presented with isolated nodal swelling. Surgery was performed in 30 patients at a nononcological hospital and was subsequently referred to our center; more than half of them needed a completion surgery at our center. Pathologically, multifocal tumors were found in close to a quarter of the patients. Among the pathological variants, classical, follicular, and tall cell variants comprised 65.7%, 28.4%, and 5.9% of the cases, respectively. Nodal positivity was noted 71.6% of the cases of which 14.5% were N1a disease and the vast majority (85.5%) harboring N1b disease. The median follow-up period of the study cohort was 104 months during which there were 3 local, 6 nodal, and 2 systemic recurrences. The 5- and 10-year disease-free survival were found to be 85.9% and 81.4%, respectively. Univariate and multivariate analysis has shown no significant clinical and pathological feature defining the disease outcomes except for the T-stage. Logistic regression revealed extrathyroidal invasion and the age ≤ 15 years correlated with nodal positivity. Conclusion: Being a rare malignancy, pediatric and adolescent PTCs tend to behave differently from adult PTC with a seemingly aggressive clinical presentation; however, they are associated with excellent survival outcomes.

A survival study of cervical cancer in Chennai, India.

A total of 4304 cervical cancer cases registered during 1982-89 in Chennai registry, India, were analyzed. Relative survival at 1, 3 and 5 years were 90%, 72% and 60% respectively. Age at diagnosis and extent of disease emerged as statistically significant prognostic factors (p<0.001). Five-fold higher risk of death was seen among those above 64 years vs. <45 years and those with distant metastasis vs. localized disease at diagnosis. Cancer control programs focusing on health education would motivate women to attend hospital at an early stage of disease for better survival.
