The re-naming of noninvasive follicular variant papillary thyroid cancer to the apparently non-malignant, noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) impacts the prevalence of malignancy rates, thereby affecting mutation frequency in papillary thyroid cancer. Preoperative assessment of such nodules could affect management in the future. The original publications following the designation of the new nomenclature have been extensively reviewed. With the adoption of NIFTP terminology, a reduction in the follicular variant of papillary thyroid cancer (FVPTC) prevalence is anticipated, as is a modest reduction of papillary thyroid cancer (PTC) prevalence that would be distributed mainly across indeterminate thyroid nodules. Identifying NIFTP preoperatively remains challenging. RAS mutations are predominant but the presence of BRAF V600E mutation has been observed and could indicate inclusion of the classical PTC. The histological diagnosis of NIFTP to designate low-risk encapsulated follicular variant papillary thyroid cancers (EFVPTCs) would impact malignancy rates, thereby altering the mutation prevalence. The histopathologic criteria have recently been refined with an exclusion of well-formed papillae. The preoperative identification of NIFTP using cytomorphology and gene testing remains challenging.

Objective: To determine the cases of Noninvasive Follicular thyroid neoplasm with papillary like nuclear features (NIFTP) in Pakistani population retrospectively. Another objective was to determine their clinical and radiological outcomes with respect to local and systemic disease recurrence, reconfirming the benign course of this new nomenclature in Thyroid tumors by WHO in our population would encourage adopting the new conservative treatment approach in such patients. Methods: This is a retrospective cohort study conducted at a tertiary care center in Karachi, Pakistan from 2007-2016. All follicular Variant papillary thyroid cancer (FVPTC) reported from a single institute had their histopathology slides reexamined for diagnosing NIFTP as per the new WHO criteria. These cases were then followed retrospectively from their diagnosis onset through their medical and electronic health record for any local or systemic disease recurrence. Results: There were 199 cases of Papillary Thyroid cancer (PTC) which included 22 cases of FVPTC. Eleven cases fulfilled NIFTP criteria with tumor size ranging from 1.1cm to ≥ 5.5cm. All patients in the NIFTP group underwent total thyroidectomy. Nine patients (81.81%) received RAI131 therapy. Four (45%) patients had a median follow up of three to four years. There was no disease recurrence seen on both ultrasound and RAI scans of patients in the NIFTP group. Seven patients (87.5%) had normal surveillance thyroglobulin levels except one whereas three patients were lost to follow up. There was no disease recurrence seen both radiologically and biochemically in the NIFTP group. Conclusion: Our study favors the low risk nature of NIFTP with no disease recurrence in the cases studied and encourages de-escalation of treatment. doi: https://doi.org/10.12669/pjms.36.2.1123 How to cite this:Jabeen S, Fatima S, Sheikh A, Islam N.

Abstract Background An abrupt increase of thyroid cancer has been witnessed paralleling the supplemented iodine intake in formerly iodine-deficient countries. And increased iodine intake has been linked to the rising incidence rate of papillary thyroid cancer (PTC). However, the correlation between iodine and clinicopathological features of PTC has not been well-characterized. This study aimed to investigate the associations between iodine intake and the clinicopathological features of PTC patients. Methods Three hundred and fifty-nine PTC patients who received surgical treatment in Peking Union Medical College Hospital from May 2015 to November 2020 were retrospectively reviewed. The associations between urinary iodine (UI), urinary iodine/creatinine ratio (UI/U-Cr), and the clinicopathological features of PTC were analyzed. Univariate and multivariate analysis were performed to investigate the relationship between UI level and central lymph node metastasis (CLNM). Results There were no significant differences in UI in different groups according to the variables studied, except that patients with CLNM had higher UI level than CLNM(−) patients. No associations were found between UI/U-Cr and clinicopathological features except variant subtypes (classic/follicular). After dividing patients into high-iodine group and low-iodine group, more patients were found to have CLNM in the high-iodine group (p = 0.02). In addition, younger age, larger tumor size, and classic variant were positively correlated with CLNM (p < 0.05). Univariate analysis showed that insufficient iodine intake (≤ 99 μg/L) was associated with decreased CLNM risk in PTC. And after defining insufficient iodine intake as ≤ 109 μg/L and above requirements as ≥ 190 μg/L, multivariate analysis showed that lower iodine was associated with CLNM in total population of PTC (OR 0.53, 95% CI 0.31–0.91) and in PTC < 1 cm (papillary thyroid microcarcinoma, PTMC) (OR 0.43, 95% CI 0.21–0.87). Conclusions Low iodine was a protective factor for CLNM in papillary thyroid cancer, particularly in those < 1 cm. These results indicated that iodine may not only be an initiator of tumorigenesis, but also a promoter of the development of PTC.

Pathological diagnosis of follicular variant of papillary thyroid carcinoma has high inter and intra-observer variability among expert pathologists, aff ecting prognosis and management of the disease. A recent study applying strict diagnostic criteria and long-term follow up confi rmed the indolent behavior of a subtype of these tumors. They recommended a nomenclature change to noninvasive follicular thyroid neoplasm with papillary-like nuclear features, refl ecting the low risk of adverse outcomes. We searched the pathology archives of King Abdulaziz University Hospital from 2002-2016 for all cases diagnosed with “follicular variant of papillary thyroid carcinoma”. Clinical data, and imaging fi ndings were retrospectively reviewed. Available pathologyslides were reviewed using the proposed inclusion and exclusion diagnostic criteria. We confi rmed the diagnostic reproducibility of the suggested criteria. Ten out of 37 cases met the diagnostic criteria. Eightadditional patients could have had their diagnosis modifi ed if sufficient tissue samples were available. Follow up data confi rmed the indolent behavior in these cases with no recurrence or adverse outcome. We concluded that application of the new diagnostic criteria for this subtype is reasonable and has major ramifi cations for the diagnosis and management as this will spare unnecessary thyroidectomies, radioactive iodine therapy, and their complications.
