Background & Objective: One of the most prevalent endocrine system cancers is papillary thyroid carcinoma, with complicated predisposing factors and pathogenesis. YAP1 (Yes-associated protein 1) is a well-known oncogene; its activity is increased in a variety of human malignancies and has recently been paid great attention. The present study examines YAP1 and P53 immunohistochemical expression in papillary thyroid carcinoma and investigates the association of their expression with the available clinicopathological risk factors to assess their possible prognostic role.
Methods: The current study used paraffin blocks of 60 cases of papillary thyroid carcinoma, which were immunohistochemically assessed for YAP1 and p53 expression. The study examined the association of their expression with clinicopathological characteristics.
Results: YAP1 expression was observed in 70% of papillary thyroid carcinoma cases. A statistically significant relation was observed between YAP1 expression and tumor size, tumor stage, tumor focality, lymph node metastases, and extrathyroidal extension (P-values were =0.003, > 0.001, 0.037, 0.025, and 0.006), respectively. p53 expression was observed in 85% of papillary thyroid carcinoma cases. A statistically significant relation was observed between p53 expression and tumor size (=0.001) and tumor stage (>0.001). A statistically significant relation was noticed between YAP1 and P53 expression (=0.009).
Conclusion: YAP1 expression was found to be associated with many high-risk clinicopathological characteristics in patients with papillary thyroid carcinoma and with p53 expression; thus, it seems that YAP1 may have a specific impact on the patient's outcome.

In non-papillary follicular cell-derived thyroid carcinomas, prognostic factors are scarce. Intratumoral fibrosis was identified as an adverse factor in papillary and medullary carcinomas, but it has not been investigated in other subtypes. We aimed at exploring the presence of intratumoral fibrosclerosis in a cohort of 132 non-papillary follicular cell-derived thyroid carcinomas (53 follicular and 31 oncocytic carcinomas, including 10 high grade differentiated thyroid carcinomas and 48 poorly differentiated carcinomas) and correlating its presence and extent with clinical and pathological features and survival.

Background: Traditional teaching dictated that patients with recurrent thyroid cysts undergo excision owing to a 12% risk malignancy. Ultrasound evaluation now determines management of these patients augmented by fine needle biopsy. In UK, a non-diagnostic category for thyroid cysts (Thy1c) exists, whereas the Bethesda system combines 'non-diagnostic-cyst fluid only' into Category I along with paucicellular and acellular results.

Given the female predominance of thyroid cancer (TC), particularly in the reproductive age range, female sex hormones have been proposed as an aetiology; however, previous epidemiological studies have shown conflicting results. We conducted a pooled analysis using individual data from 9 prospective cohorts in the Asia Cohort Consortium, to explore the association between 10 female reproductive and hormonal factors and TC risk. Using Cox proportional hazards models, cohort-specific hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated and then pooled using a random-effects model.

Context: In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes.
Objective: Thyroid gland diseases are commonly encountered in society. This study presents health-related quality of life differences in thyroidectomies performed for benign and malignant diseases and the factors affecting this.

Objective: Few prognostic analyses have been conducted for papillary thyroid cancer (PTC) patients with preablative stimulated Tg >10 ng/mL. We investigated the therapeutic responses and prognosis of these patients after the initial radioiodine (RAI) therapy.
Methods: We retrospectively assessed 256 patients with PTC who underwent RAI remnant ablation after total thyroidectomy, and all presTg levels were >10 ng/mL.
