“…Shortly after Söderström in Sweden described thyroid fine-needle aspiration (FNA) cytology in 1952, it was introduced to Japan [ 1 , 2 ]. In as early as 1972, Toriya published his first report on thyroid FNA cytology (in Japanese with an English abstract) from Ito Hospital (a thyroid center in Tokyo, Japan) [ 3 ] where more than 1,000 surgical procedures for thyroid disease were carried out every year. His cytological diagnostic criteria were descriptive and similar to those for pathological diagnosis of surgical specimens.…”

In Japan, fine-needle aspiration (FNA) cytology is the most important diagnostic modality for triaging patients with thyroid nodules. A clinician (endocrinologist, endocrine surgeon, or head and neck surgeon) generally performs FNA cytology at the outpatient clinic, and ultrasound (US)-guided FNA is widespread because US is extremely common and most clinicians are familiar with it. Although almost all FNA thyroid samples are examined by certified cytopathologists and pathologists, some clinicians assess cytological specimens themselves. In Japan, there are two clinical guidelines regarding the management of thyroid nodules. One is the General Rules for the Description of Thyroid Cancer (GRDTC) published by the Japanese Society of Thyroid Surgery (JSTS) in 2005, and the other is the national reporting system for thyroid FNA cytology published by the Japan Thyroid Association in 2013 (Japanese system). Although the Bethesda System for Reporting Thyroid Cytopathology (Bethesda system) is rarely used in Japan, both the GRDTC and Japanese system tried to incorporate the Bethesda system so that the cytological diagnoses would be compatible with each other. The essential point of the Japanese system is stratification of follicular neoplasm (FN) into three subgroups based on cytological features in order to reduce unnecessary diagnostic thyroidectomy, and this system has been successful in stratifying the risk of malignancy in FN patients at several high-volume thyroid surgery centers. In Japan, the measurement of thyroglobulin and/or calcitonin in FNA needle washings is often used as an adjunct for diagnosis of possible cervical lymph node metastasis when FNA cytology is performed.

“…Thyroid malignancies represent approximately 5% of all thyroid nodules and malignancies presenting as a diffuse enlargement is extremely rare (15,16). Equally, about 60% of thyroid nodules show benign cytology in clinical practice (1)(2)(3)(4)(5)(6)(7)(8). An allowance should be made to these figures depending on the geographical location and associated environment factors.…”

“…If hotspots, such as locations and countries with increased exposure to radiation and iodine deficiency are excluded above figures may be generalized globally. It is noteworthy that benign and malignant cytological categories are comparable in incidence and do not appear to provoke significant controversy in terms of categorisation or diagnostic criteria in a global setting (1)(2)(3)(4)(5)(6)(7)(8). When malignant and benign diagnoses are excluded approximately 35% of cytological diagnosis of all thyroid nodules fall into an 'inconclusive/uncertain group' (1)(2)(3)(4)(5)(6)(7)(8).…”

This uncertain group that includes non-neoplastic and benign neoplastic lesions as well as a proportion of differentiated malignant neoplasms is the central focus that needs guidance in terms of sampling, interpretation, terminology and management.…”

“…The Bethesda system for reporting thyroid cytology (TBSRTC) infused great enthusiasm around the world to standardize a challenging area of cytopathology (1). Prior to this many other systems have been in operation mainly in an 'ad hoc' fashion within institutions and countries (2)(3)(4)(5). Currently, in addition to the TBSRTC developed in the USA, there are several reporting systems and guidelines recommended and adopted by professional societies in countries such as UK, Japan, Italy and Australia (5)(6)(7)(8).…”

Standardisation of thyroid cytology terminology and practice: are modifications necessary?—a narrative review

Universally accepted guidelines for diagnosis and management of any disease are desirable.Standardization of thyroid cytology reporting is aimed at guiding and improving clinical decision-making and management. However, socio-economic, and local factors and differences in disease prevalence and patterns require modification to suit local settings. 'One size fit all' approach is not possible for any disease diagnosis or management. The same concept is applicable in diagnosis and management of thyroid nodules.An additional special issue is the well-known high inter and intra-observer variability in the histological and cytological diagnosis of thyroid neoplasms. Despite this, thyroid cytology has a very significant influence in the management of thyroid diseases. An approach based on common principals with appropriate modifications that suits countries or continents is desirable and sustainable. The principals of TBSRTC have served as a framework for similar tiered classifications for reporting thyroid cytopathology. This article discusses globally available professional guidelines based on a common framework with appropriate modifications, with the universal aim of risk stratification of thyroid nodules.
