PROGNOSTIC FACTORS OF THYROID CANCER AND FIVE-YEAR SURVIVAL RATE

ABSTRACT
The objective of the study is to determine the prognostic factors of thyroid cancers and five years survival rate of thyroid
cancers.
Material and methods: The study was descriptivestudy from 1st January 2007to 31st December 2009, followed for 5
years till 2014 (of 8 years duration) at ENT and Surgical departments Khyber Teaching Hospital and Hayatabad Medical
Complex, Peshawar. Total number of 312 patients having thyroid cancers enrolled from admitted patients. The prognostic
factors like age and sex of the patient, type of tumour and stage of tumour were studied. The patients included
in the study were those diagnosed as thyroid cancers confirmed by tissue biopsy either FNAC or after lobectomy/
thyroidecomy. The cancers were staged using TNM staging system. All the patients were followed for five years after
diagnosis irrespective of treatment.
Results: In our study the 5-year survival rate for less than 40 years of age was 90.1%, for 41-60 years 90.6% and more
than 60 years 78%. The 5-year survival rate for femalesis better with (93.6%) as compare to males(73.1%). The 5-year
survival rates for papillary carcinoma (90.5%) as compare to other thyroid carcinomas is good as well as early stage
tumours (stage I and II which is 100%) do better than late stage tumours (stage III and IV).
Conclusion: Early age, female sex, early stage and well-differentiated thyroid cancers have better prognosis.
Key Words: Prognostic factors of thyroid cancer, 5 years survival rate of thyroid cancers.
