ABSTRACT
Background: Surgery is the mainstay in the management of thyroid cancer. Surgical outcomes need to be tempered against the excellent prognosis of the disease. Aims: This study aims to study the surgical outcomes including the 30-day morbidity and 5-year survival of thyroid cancer patients. Settings and Design: Retrospective analysis of a prospectively maintained surgical database in a tertiary cancer center in India. Materials and Methods: We analyzed 221 surgically treated patients in the year 2012. Statistical Analysis: Used IBM SPSS 24.0 (Armonk, NY) with p < 0.05. Results: The median age was 40 years with predominantly papillary thyroid carcinoma (55%). Localized disease in 47% of cases, locoregional disease in 42.5% and distant metastasis in 10.2% of cases at presentation was noted. Treatment naïve patients were 71% and revision surgeries were done in 29% patients. Extended thyroidectomy constituted 11% of the surgeries. Temporary hypocalcemia was seen in 30.8% of patients, 5% requiring intravenous calcium supplementation. Vocal cord palsy as per nerve at risk and chyle leak were seen in 4.5% and 3.1%, respectively. Aggressive histology, extended thyroidectomy, and inadvertent parathyroidectomy were significant factors associated with complications. Five year estimated overall survival with median follow-up of 50 months was 98%, and event-free survival was 84.8%. Advanced age, distant metastasis at presentation and aggressive histology connoted poor outcomes. Conclusion: Thyroid cancer, irrespective of the extent of disease, has good prognosis. Aggressive histology, the extent of thyroid surgery, distant metastasis and age are important factors, which should be factored in the algorithm of thyroid cancer management.
ABSTRACT
This study was carried out to observe the trend in hormone receptors over the last 8 years in a tertiary cancer center in India. A total of 11,780 tumors analyzed for hormone receptors over the last 7 years were compared with the results of hormone receptor expression in a prior published study on 798 cases of breast cancer from the same institute. The patient's ages ranged from 18 to 102 years, Sixty percent of the patients were in the age group of 31-50 years. Seventy percent of the tumors were grade III tumors. The percentage of hormone receptor expression in breast cancer in the last 8 years varied from 52 to 57%. The overall receptor expression in the last 8 years shifted within a 5% range, confirming that the hormone receptor expression in Indian patients with breast cancer is low. However, there was redistribution within the pattern of estrogen receptor (ER) and progesterone receptor (PR) expression among tumors showing hormone receptor expression. Breast cancers showing only PR expression reduced dramatically from 21% in the year 1999 to in the year 2006, with a parallel increase in breast cancers showing combined ER and PR positivity (from 25 to 41.8%) and only ER expression (from 7.4 to 10.6%). The hormone receptor expression in breast cancers in India is and continues to be low but the high incidence of only PR-positive tumors in our population reported earlier was misrepresented.
