Sir,

In the article, “Thyroid cancer: Controversy about overdiagnosis versus the perils of under diagnosis” by Unnikrishnan et al., few valid points are discussed.[1] As they have stated in India, the problem may be due to under diagnosis rather than overdiagnosis. Data from different centers from all the regions of our vast country should be encouraged and analyzed systematically to know the true incidence and prevalence of various thyroid malignancies. In a recently conducted study in our center in South India, we had 162 cases of solitary thyroid nodules (STN) detected clinically. For 146 patients with clinically detected STN, ultrasonography (USG) findings were available.[2] USG findings of solid echogenicity, presence of microcalcification in nodule, and associated cervical lymphadenopathy were more associated with malignancy as per final histopathology reports. All our patients underwent fine-needle aspiration cytology (FNAC) before surgery. Based on these reports, we performed hemithyroidectomy of the involved side and opted for either frozen section or for routine histopathological examination. In view of frozen section report of malignancy in thyroid nodule, completion thyroidectomy was done. The complications such as postoperative hypocalcemia were seen in 8.9% of our patients and recurrent laryngeal nerve injury in 2.7% patients. Hence, complications should not deter us from diagnosing and operating a thyroid malignancy.

Remonti et al. in a large meta-analysis have stated that only USG features do not provide reliable information regarding the risk of malignancy in a given patient. They should be evaluated in relation to clinical and FNAC findings. In addition, they have also advocated standardization of elastography techniques.[3]

In our country, all these may not be possible and financially viable. But, definitely pooling of all the available data from various small and large centers would help to generate reliable data regarding incidence and prevalence. This will help in arriving at consensus guidelines for the management of thyroid malignancies.
