Material and methods: Retrospective review of patients with thyroid cancer at our hospital from 1999 to 2011 was done.

Results: Mean age at presentation was 44±17 years with female to male ratio of 2.1:1. Patients were followed for mean of 6.45 and median of 6 years. Out of 206 patients, 158 had differentiated thyroid carcinoma. Most common variant was papillary (n=130, 63.10%) followed by follicular carcinoma (n=22, 8.73%). 6 (2.91%) had hurthle cell variant of follicular carcinoma. 18 (8.73%) had medullary and 10 (4.85%) had anaplastic carcinoma. 20 (9.70%) patients had other causes like carcinoma of undetermined significance, metastatic carcinoma and lymphoma.

Patients having DTC, 70 (44.3%) were diagnosed at stage 1, 17 (10.8%) at stage 2, 12 (7.6%) at stage 3 and 29 (18.3%) have stage 4 disease. 2 (14.3%) patients with medullary carcinoma were diagnosed at stage 1, 4 (28.6%) at stage 3 and 8 (57.1%) were at stage 4. All patients with anaplastic carcinoma had stage 4 disease. Overall cure rate was 33.5%, persistence rate 26.6%, recurrence was 8.2% and thyroid cancer related mortality was 8.9%.

By univariate analysis age, cancer types, distant metastasis, type of surgery and thyroglobulin levels were significant prognostic factors. By multivariate analysis age ≥ 45 years (P=0.04), distant metastasis at the time of presentation (P=0.04), thyroglobulin levels ≥ 8 right after surgery (P≤ 0.001) were found to be independent prognostic factors. Furthermore, other factors like gender and thyroglobulin doubling time did not show any association with the prognosis of thyroid carcinoma.

Conclusion: The current study demonstrated an assessment of prognostic factors in this cohort. Age at diagnosis, distant metastasis and thyroglobulin levels were found to be strong prognostic factors for thyroid carcinoma.
