Observational Study
The association between cytology and histopathology in thyroid nodules over a 6-year period in an urban hospital in South Africa.
Thyroid cancer is prevalent both internationally and locally, and is the most common cause of endocrine malignancies in Africa. The prognosis of thyroid cancer in general is quite good, but to achieve good outcomes, appropriate methods for diagnosis are important. A cytology result obtained from a fine needle aspiration and biopsy (FNAB) is one such method, and is less invasive and has less risk compared with obtaining a histological result via open surgery. However, there are accuracy differences that have been reported in different literature findings. ⋯ There was good correlation between cytology and histology for thyroid nodules. Differences were noted between the percentage of malignant cases in the different Bethesda categories compared with international standards as noted above. We recommend that further studies are conducted locally to improve knowledge on this topic.

Upon the addition of the numbers corresponding to various cancer anatomical locations in the report published by Statistics South Africa (StatsSA), the absolute number and proportion of deaths due to all cancers increased from 36 726 (8.0%) in 2013 to 40 460 (8.5%) in 2015. These high figures suggest that malignant neoplasms were in fact the second-most frequent cause of death in South Africa (SA) in 2013, and moved to the first rank in 2015. ⋯ Cancer mortality rates have increased since 1997, regardless of gender. Overall, there was a decline in YPPLL for cancer in the young population, while it increased in the adult population. A significant reduction in cancer deaths could be achieved by broadly applying effective interventions.
