Use of a low-cost telecytopathology method for remote assessment of thyroid FNAs.

BACKGROUND: Rapid on-site evaluation is a great tool for optimizing the adequacy and quality of cytologic samples. The objective of the current study was to analyze a low-cost telecytopathology method for the remote assessment of thyroid fine-needle aspiration biopsies (FNABs), with comparison of the primarily rendered adequacy and diagnosis with the final conventional analysis. METHODS: Material collected from thyroid FNABs was immediately smeared onto glass slides and stained with Diff-Quik. A conventional microscope attached to a smart device was operated on-site by either a medical student or a pathology resident for Wi-Fi transmission of the images by Skype. The cytopathologist would remotely guide the screening of the slides, zooming in and out of areas of interest. Remote assessment included an analysis of material adequacy and a preliminary diagnosis. The quality of the transmission and the number of slides also were recorded. After a washout period of 3 weeks, final diagnosis and adequacy were assigned by conventional microscopy. RESULTS: The final agreement rate for adequacy between remote and conventional analysis was 90.5%. For diagnosis, the final agreement rate was 83.3%. The diagnosis agreement rate varied, depending on the quality of transmission: there was 88% agreement when the quality was excellent, 77.8% agreement when it was good, and 62.5% agreement when it was poor. CONCLUSIONS: Low-cost telecytopathology is an efficient method for the remote assessment of thyroid FNAB adequacy and diagnosis. The wide use of such technology in low-resource or remote centers may have a positive impact on the number of adequate or satisfactory samples, optimizing the management of patients who have thyroid nodules.

[Application of fibrin sealant in patients operated on for differentiated thyroid cancer. What do we improve?]. / Aplicación de sellante de fibrina en pacientes operados por cáncer diferenciado de tiroides. ¿Qué mejoramos?

BACKGROUND: In recent years, several publications have shown that new adhesives and sealants, like Tissucol(®), applied in thyroid space reduce local complications after thyroidectomies. STUDY AIMS: To demonstrate the effectiveness of fibrin glue Tissucol(®) in reducing the post-operative hospital stay of patients operated on for differentiated thyroid carcinoma in which total thyroidectomy with central and unilateral node neck dissection was performed (due to the debit drains decrease), with consequent cost savings. MATERIAL AND METHODS: A prospective randomised study was conducted during the period between May 2009 and October 2013 on patients with differentiated thyroid carcinoma with cervical nodal metastases, and subjected to elective surgery. Two groups were formed: one in which Tissucol(®) was used (case group) and another where it was not used (control group). Patients were operated on by surgeons specifically dedicated to endocrine surgical pathology, using the same surgical technique in all cases. RESULTS: A total of 60 total thyroidectomies with lymph node dissection were performed, with 30 patients in the case group, and 30 patients in control group. No statistically significant differences were observed in most of the studied variables. However, the case group had a shorter hospital stay than the control group with a statistically significant difference (p<0.05). CONCLUSION: Implementation of Tissucol(®) has statistically and significantly reduced the hospital stay of patients undergoing total thyroidectomy with neck dissection, which represents a significant reduction in hospital costs. This decrease in hospital stay has no influence on the occurrence of major complications related to the intervention.

Attributable costs of differentiated thyroid cancer in the elderly Medicare population.

BACKGROUND: Little is known about costs associated with differentiated thyroid cancer (DTC) and follow-up care. This study used data from the Surveillance Epidemiology and End Results (SEER) database to examine cumulative costs attributable to disease stage and treatment options of DTC in elderly patients over 5 years. METHODS: We identified 2,823 patients aged >65 years with DTC and 5,646 noncancer comparison cases from SEER Medicare data between 1995 and 2005. Cumulative costs were obtained by estimating average costs/patient in each month up to 60 months after diagnosis. We performed multivariate analyses of costs by fitting each monthly cost to linear models, controlling for demographics and comorbidities. Marginal effects of covariates were obtained by summing coefficients over 60 months. RESULTS: Cumulative costs were $17,669/patient the first year and $48,989/patient 5 years after diagnosis. Regional disease was associated with higher costs at 1 year ($9,578) and 5 years ($8,902). Distant disease was associated with 1-year costs of $28,447 and 5-year costs of $20,103. Patients undergoing surgery and radiation had a decrease in cost of $722 at 5 years. CONCLUSION: DTC in the elderly is associated with significant economic burden largely attributable to patient demographics, stage of disease, and treatment modalities.
