RESUMEN

BACKGROUND: Global data reports a low malignancy risk, whereas regional data report a variable risk of malignancy in Bethesda II thyroid nodules. The limited availability of surgical histopathology might have underestimated the risk of malignancy. Here, we report the prevalence of malignancy and its predictors in Bethesda II thyroid nodules for which the surgical histopathological diagnosis was available. METHODS:  This retrospective study was done at a tertiary healthcare center in South India between January 2008 and September 2015. Case records of adults with thyroid nodules who underwent surgery were collected. Patients with inadequate data were excluded from the study. The data was analyzed using SPSS version 21.0 and a p-value of < 0.05 was considered statistically significant. RESULTS:  A total of 563 patients were included in the study with a mean age of 36±12 years. Serum thyrotropin (TSH) was low in 87 (15.4%) patients whereas 362 (64.2%) patients had multinodular goiter (MNG). Sonographic evidence of suspicious cervical lymph node and microcalcification was seen in four (0.7%) and 48 (8.5%) patients, respectively. A total of 48 (8.5%) patients had thyroid carcinoma in the final histopathology. Of these, 42 (87.5%) had papillary thyroid carcinoma, five (10.4%) had follicular thyroid carcinoma and one (4.1%) had anaplastic carcinoma. Age, gender, and maximum nodule size were not associated with malignancy. Thyrotoxicosis was negatively associated with malignancy whereas multi-nodularity, thyroid calcification, or suspicious cervical lymph node on ultrasound and total thyroidectomy were positively associated with malignancy on univariate analysis. On binary logistic regression, only the former four, but not total thyroidectomy, were independent predictors of malignancy. CONCLUSIONS:  We report a high (8.5%) prevalence of malignancy among South Indian patients with Bethesda II thyroid nodules. Thyroid microcalcification, presence of suspicious cervical lymph node on ultrasound, and multinodularity were associated with high and suppressed TSH with low risk of malignancy. Further prospective studies are warranted to confirm the study observations.

RESUMEN

Background: As the novel coronavirus disease 2019 (COVID-19) continues its pandemic surge globally, the attention toward the treatment of non-COVID diseases has become difficult. Software-based systems and social media platforms could provide alternatives for ensuring regular health-care non-COVID diseases. In this context, we evaluated our own experience with virtual consultation (VC) for the management of endocrine surgical patients during the current COVID pandemic. Materials and Methods: This prospective study was conducted in the endocrine surgery department spanning 4 months from April to July 2020. We employed WhatsApp-based group video conferencing for VC with both new and follow-up outpatients. We evaluated the satisfaction quotient of patients, regarding the three types of consultations (no consultation, VC, and direct consultation) on an ordinal scale of three modes of consultation. Results: Virtual consultation was performed with 102 new and 285 follow-up patients. Goiters, clinical findings, and wounds/scars (in post-operative cases) were evaluated virtually. Dosage of thyroxine replacement, calcium supplementation, and other medications was prescribed based on findings and history. Patients who needed surgery (25/102 cases) were given appropriate appointment. More than 82% of the patients in both groups preferred VC during this COVID pandemic. Conclusions: More than 82% of both new and follow-up patients preferred VC over direct or no consultation during this COVID pandemic. Our findings suggest that VC through social media platforms is capable of ensuring appropriate treatment and follow-up for endocrine diseases.

RésuméContexte: Alors que la nouvelle maladie à coronavirus 2019 (COVID-19) poursuit sa poussée pandémique à l'échelle mondiale, l'attention portée au traitement des maladies non-COVID est devenue difficile. Les systèmes logiciels et les plates-formes de médias sociaux pourraient fournir des alternatives pour garantir soins de santé courants maladies non COVID. Dans ce contexte, nous avons évalué notre propre expérience de consultation virtuelle (VC) pour la gestion des patients en chirurgie endocrinienne pendant la pandémie actuelle de COVID. Matériels et méthodes: Cette étude prospective a été menée dans le service de chirurgie endocrinienne s'étendant sur 4 mois d'avril à juillet 2020. Nous avons utilisé la visioconférence de groupe basée sur WhatsApp pour VC avec les nouveaux patients et les patients de suivi. Nous avons évalué le quotient de satisfaction des patients, concernant les trois types de consultations (pas consultation, CV et consultation directe) sur une échelle ordinale de trois modes de consultation. Résultats: Une consultation virtuelle a été effectuée avec 102 nouveaux patients et 285 patients suivis. Les goitres, les signes cliniques et les plaies/cicatrices (dans les cas postopératoires) ont été évalués virtuellement. Le dosage du remplacement de la thyroxine, de la supplémentation en calcium et d'autres médicaments a été prescrit en fonction des résultats et des antécédents. Les patients qui chirurgie nécessaire (25/102 cas) ont reçu un rendez-vous approprié. Plus de 82 % des patients des deux groupes ont préféré la CV au cours de cette Pandémie de covid. Conclusions: plus de 82 % des nouveaux patients et des patients de suivi ont préféré la CV à la consultation directe ou à l'absence de consultation pendant cette période. Pandémie de covid. Nos résultats suggèrent que la CV via les plateformes de médias sociaux est capable d'assurer un traitement et un suivi appropriés pour les maladies endocriniennes.

RESUMEN

Poorly differentiated thyroid cancer (PDC) and especially poorly differentiated areas (PDA) within follicular cell-derived differentiated thyroid cancer are ill-defined clinicopathological entities. We report our experience on their comparative prognostic outcomes This is a retrospective study of 61 patients (PDC = 29; PDA = 32) from Endocrine and Metabolic Surgery Department (2009 to 2017). Clinical and follow-up details are collected and digitally tabulated from departmental database. Gender ratio was M:F = 1:1.3 and 1:1.6. Mean age was 51 ± 12 years (16-76) and 54 ± 10.5 years (36-81) in PDA and PDC, respectively. Mean tumour size (4.6 ± 0.9 cm; 4.9 ± 1.2 cm), extrathyroidal invasion (59%; 73%) and regional lymphadenopathy were 50% and 55% in PDA and PDC, respectively. Total thyroidectomy was possible in 94% of PDA and in only 77% of PDC. Radioiodine ablation was utilised in 65% (PDA); 29% (PDC). With mean follow-up of 64 ± 23.5 months (12-103) in PDA and 37 ± 22 months (6-94) in PDC, nodal recurrence (PDC = 29%; PDA = 22%) and systemic metastasis was 41% in PDC (synchronous = 24%; metachronous = 17%); 19% in PDA (synchronous = 16%; metachronous = 3%). Five-year event-free survival (EFS) and overall survival (OS) was 90% and 93% in PDA, and 42% and 44% in PDC, respectively. Our study shows that PDA is a separate clinicopathological entity with significantly positive prognosis compared to PDC.

RESUMEN

BACKGROUND: The adenoma-carcinoma sequence in thyroid nodules is an enigmatic phenomenon. Genomics is the only definitive modality to resolve this hypothesis. Adenomas and papillary carcinomas tend to have mutations in RAS and highly specific BRAF gene respectively. In this context, we set out study the prevalence and clinical significance of these somatic mutations in surgical tissue samples. MATERIAL AND METHODS: This retrospective study was conducted on surgically managed thyroid nodule patients. Institutional ethical committee approval was obtained. Diagnosis was based on biochemical confirmation, imaging, fine needle aspiration cytology and later confirmed by histopathology. We selected 100 benign thyroid adenomas (BTA) and 100 papillary thyroid carcinoma (PTC) cases. Archived tumour tissue samples of selected cases were retrieved. After appropriate processing of samples, DNA extraction, cDNA preparation, PCR amplification, application of 4 sets of Primers were performed as part of mutational analysis of RAS (H-,K-,N-) and BRAF genes. RESULTS: Homozygous mutations in N-RAS were found in 36/100 (36%) of BTA and 7/100 (7%) of PTC cases. No H-RAS or K-RAS mutations were found in both groups. Homozygous mutations were found in BRAF gene in 4/100 (4%) of BTA cases and 52/100 (52%) of PTC cases. The differences were statistically significant. CONCLUSIONS: Similar N-RAS and BRAF mutations were prevalent in both benign and malignant thyroid nodules giving some evidence for linkage between them. Though not robust, we opine that there is possibility of adenoma-carcinoma sequence in thyroid nodules.
