“…Although our study focused on second rather than primary or index thyroid cancer, our finding about the association between gender and development of thyroid cancer is consistent with what is well known in the cancer epidemiology literature in the United States and globally about gender disparities in incidence of thyroid cancer . The significantly increased rate of SPTC in the Asian and Alaskan Native populations is consistent with recent incidence data that suggest there is also increasing incidence of both thyroid and HNC in both populations . This is important, because minority populations, including Asians and Alaskan Natives, may have poorer access to care and are less likely to present with early‐stage disease .…”

“…Keane et al, in a review of eight retrospective cohort studies, with a total of 611 777 patients, found out that black and white patients have a higher proportion of follicular cancer, than Hispanics, though the later have a younger age at diagnosis [74]. Also, Week et al, reported that the white population has a greater proportion of diagnosed small tumors (papillary microcarcinomas) than non whites, attributable to their being more medical insured, and thereby susceptible to "unnecessary" investigations and overtreatment [75].…”

Introduction: Thyroid cancer incidence is increasing globally. This increase has been attributed to improvement in diagnostic methods. This study has as its aim the analysis of the pattern of thyroid gland malignancies seen at the Jos University Teaching Hospital, Jos, Nigeria, between January 2008 and December 2018. Methodology: A descriptive retrospective study of consecutive cases of thyroid specimens analyzed at our center was done. Data was obtained from the Histopathology Department Records. The diagnosis of each case was confirmed by reviewing archival slides. Results: There were 70 cases of thyroid carcinomas during the period of the study. The histological types of thyroid cancers seen were: follicular carcinoma, papillary carcinoma, medullary carcinoma and anaplastic carcinoma, respectively accounting for 36(51.4%), 23(32.9%), Emmanuel et al.; JAMMR, 29(12): 1-10, 2019; Article no.JAMMR.49712 2 4(5.7%) and 7(8.6%) cases. There was only 1 case of follicular carcinoma in 2012, and non between 2013 and 2018. The male to female ratio was 1: 3.1. The mean age of thyroid carcinoma was 42.7 years, with an age range of 13-80 years. Conclusion: The histological pattern of thyroid cancers has changed over the last two decades in our environment with the erstwhile predominant follicular carcinoma receding to near disappearance. The papillary carcinoma histotype is currently overwhelmingly the commonest type diagnosed. The former is relatively commonly seen in the older age group, in a sharp contrast with the later. The female gender remains the most afflicted group. Original Research Article

“…Recent genome‐wide association studies have identified the Chinese population to be at an increased risk for PTC. A recent study by Weeks et al found Asians to have a 40% higher odds than Caucasians of being diagnosed with PTC. Further, this study found Asians to have significantly higher age‐adjusted incidence rates for more advanced stage tumors when compared to Caucasians …”

Unexpected high‐risk pathologic features following thyroidectomy in the chinese immigrant population

Objective To compare rates of unexpected high‐risk pathologic features between Chinese and non‐Asian patients who underwent thyroidectomy for papillary thyroid cancer. Methods This was a retrospective cohort study at a tertiary academic urban medical center. Patients who underwent thyroidectomy for papillary carcinoma from 2015 to 2017 were included. Patient demographics, tumor characteristics, and tumor histopathology were analyzed. Primary outcome was the presence of adverse histopathologic features such as lymphovascular invasion (LVI) or microscopic/minimal extrathyroidal extension (mETE). Differences between the groups were analyzed using multivariate logistical regression analysis and propensity score‐weighted analysis. Results One hundred seventy‐nine patients were included: 58 Chinese‐born and 121 non‐Asian. The median age of the cohort was 47 years old (36–58). Twenty‐nine percent of patients were male, and 71% were female. There was no statistically significant difference between the two cohorts in rates of LVI, multifocality, extent of surgery, or presence of thyroiditis. Patients with mETE were more likely to have larger tumors (P = 0.00247). Both the multivariate and propensity‐weighted models demonstrated that Chinese ancestry was independently associated with an increased rate of unexpected mETE (adjusted prevalence ratio, 2.52; 95% confidence interval, 1.82–3.48). Conclusion mETE is significantly higher in the immigrant Chinese compared to the non‐Asian population. Given the high prevalence of unexpected mETE in the Chinese population, the added risk of this finding should be brought into the discussion during initial surgical planning.
