ABSTRACT
RESUMEN Material y métodos Estudio prospectivo multicéntrico. Se incluyeron 174 pacientes con CDT tratados consecutivamente desde junio 2014 hasta mayo 2015. Se los dividió en 2 grupos (ablacionados y no ablacionados) con 87 pacientes incluidos en cada uno. La respuesta inicial al tratamiento se determinó con la medición de tiroglobulina, anticuerpos anti-tiroglobulina y ecografía de cuello. Resultados Se compararon las características basales de ambos grupos y no se evidenciaron diferencias estadísticamente significativas: sexo femenino 84% y 88% (p = 0,5); edad promedio de 46,8 y 47,5 años (p = 0,7); carcinoma papilar variedad clásico 68% y 75,9% (p = 0,15), respectivamente. El resto de las características basales como tamaño tumoral, bilateralidad, multifocalidad, tiroiditis de Hashimoto y estadio tumoral tampoco mostraron diferencias significativas. La evaluación de la respuesta inicial al tratamiento se realizó en 64 pacientes del grupo ablacionado y en 76 del grupo no ablacionado. Se observó una respuesta excelente en 81% de pacientes ablacionados vs. 87% del grupo no ablacionado, con una frecuencia de respuesta estructural incompleta de 1,6% y 1,4%, respectivamente, (p = 0,9). Un 17% de los ablacionados y 12% de los no ablacionados presentaron una respuesta indeterminada. Conclusión: Los pacientes de bajo riesgo, ablacionados o no, presentan similares frecuencias de respuesta inicial excelente y estructural incompleta. El seguimiento a largo plazo podrá definir si estas respuestas iniciales se mantienen en el tiempo, lo que permitirá reducir la indicación de ablación con radioyodo en este grupo de pacientes con CDT.
ABSTRACT Patients and methods We included 174 patients; 87 patients in each group (ablated and nonablated). Assessment of the initial response to treatment was performed by measurement of thyroglobulin and anti-thyroglobulin antibodies and by neck ultrasonography. Results Baseline characteristics of both groups were compared, and no statistically significant differences were found: female sex 84% and 88,5%, respectively, (p = 0.5); mean age of 46.8 and 47.5 years, respectively (p = 0.7); papillary carcinoma classic variant 68% and 75.9%, respectively (p = 0.15). The remaining of the baseline characteristics such as tumor size, presence of bilaterality, multifocality, Hashimoto's thyroiditis and tumor stage were not statistically significant, either. The evaluation of the response to treatment was finally performed in 64 patients from the ablated group and in 76 from the non-ablated group. An excellent response to treatment was observed in 81% of ablated patients vs. 87% of the non-ablated group, with a frequency of structural incomplete response of 1.6% and 1.4%, respectively (p = 0.9). On the other hand, 17% and 12% of patients in each group had an indeterminate response. Conclusion Low-risk ablated and non-ablated patients have a similar frequency of excellent initial and structural incomplete response to treatment. Long-term follow-up is needed to establish whether these initial responses are maintained over time, and thus further refine the indications of RA in this group of patients with DTC.

OBJECTIVE: The aim of the present study was to evaluate the overall treatment efficacy (tumor control, facial nerve function, complications) and quality of life for patients treated primarily for unilateral vestibular schwannomas of 30 mm or less, either by microsurgery or by gamma knife (GK) radiosurgery. The results for the two treatment groups are compared with each other, with main emphasis on the long-term quality of life. METHODS: This is a retrospective study of 189 consecutive patients, 86 treated by microsurgery and 103 by gamma knife. The mean observation time was 5.9 years. All patients had a magnetic resonance imaging scan and clinical evaluation performed toward the end of the study. To evaluate the quality of life, we used two standardized questionnaires, the Glasgow Benefit Inventory and Short-Form 36. The questionnaires were sent to the 168 living patients. The reply rate was 83.3%. RESULTS: A total of 79.8% of the patients in the microsurgery group and 94.8% of the GK patients had a good facial nerve function (House-Brackmann Grade 1-2). Hearing was usually lost after microsurgery, whereas the GK patients had preserved hearing, which often became reduced over the years after the treatment. The treatment efficacy, defined as no need for additional treatment, was similar for the two treatment modalities. Quality of life was reduced compared with normative data, being most reduced in the microsurgery group. Some of the quality of life questions showed an association with facial nerve function and sex. CONCLUSION: Posttreatment facial nerve function, hearing, complication rates, and quality of life were all significantly in favor of GK radiosurgery.
