The aim of this study is to obtain a good strategy therapy in patients with locally advanced thyroid cancer with invasion of the large vessels of the neck and thorax which allows the correct selection of this patients that will undergo to surgery with possible adjuvant therapy. The incidence of thyroid cancer is increasing worldwide, as well as the patients with locally advanced papillary thyroid cancer that are refractory to radiometabolic treatment. This patients have a 5-year survival rate of 50% and 10-year survival rate < 10%. 54 patients were recruited from January 2016 to May 2019. The patients were divided into two arms: first arm (experimental) includes all patients who underwent a second surgical look and possible therapy with Sorafenib. The second arm (control) includes patients who underwent only Sorafenib treatment. All the recruited patients were refractory to radiometabolic treatment with 131I. In 29 patients the complete follow-up of 18 months was possible; in the remaining 15 the follow up is still ongoing. The evaluation of the regression / stability or progression of the disease was evaluated using the American Thyroid Association's risk stratification. The morphological evaluation of the lesions was performed following the RECIST criteria. The data analysis showed that there is a statistically significant difference only between the PFS (Progression Free Survival) of the control arm and that of the experimental arm in favor of the experimental arm (p = 0.0399), but observing overall survival at 18 months there is no statistically significant difference (p = 0.197), but it's to be interpreted in the light of the temporal bias or the brevity of the study of only 18 months.
L'obbiettivo di questo studio è di ottenere uno schema diagnostico-terapeutico nei casi di carcinoma tiroideo localmente avanzati con invasione dei grossi vasi del collo e del torace che permetta la corretta selezione dei pazienti da sottoporre a intervento chirurgico con eventuale terapia adiuvante. L’incidenza del carcinoma della tiroide è in aumento in tutto il mondo. I soggetti con carcinoma papillifero localmente avanzato e refrattari al trattamento radiometabolico hanno una sopravvivenza a 5 anni < del 50% e a 10< del 10%. 54 pazienti sono stati reclutati da gennaio 2016 a maggio del 2019. I pazienti sono stati divisi in due bracci: il primo (braccio sperimentale) comprende tutti i pazienti che sono stati sottoposti a second-look chirurgico ed eventuale terapia con Sorafenib; il secondo (braccio di controllo) comprende i pazienti che hanno ricevuto solo trattamento con Sorafenib. Tutti i pazienti reclutati erano già stati sottoposti a trattamento radiometabolico con 131I, ma refrattari al up-take di 131I. In 29 pazienti è stato possibile ottenere il follow-up completo di 18 mesi; nei restanti 15 il follow-up è ancora in corso. La valutazione della regressione/stabilità o avanzamento della malattia è stata valutata usando la stratificazione del rischio dell'American Thyroid Association. La valutazione morfologica delle lesioni è stata effettuata seguendo i criteri RECIST. L'analisi dei dati ha mostrato che vi è differenza statisticamente significativa solo tra la PFS (Progression Free Survival) del braccio di controllo e quella del braccio sperimentale a favore del braccio sperimentale (p=0.0399), ma osservando la sopravvivenza globale a 18 mesi non vi è differenza statisticamente significativa (p=0.197). Quest'ultimo dato è da interpretare alla luce del bias temporale ovvero la brevità dello studio di soli 18 mesi.

Abstract
The aim of this study is to obtain a good strategy therapy in patients with locally advanced thyroid cancer with invasion of the large vessels of the neck and thorax which allows the correct selection of this patients that will undergo to surgery with possible adjuvant therapy. The incidence of thyroid cancer is increasing worldwide, as well as the patients with locally advanced papillary thyroid cancer that are refractory to radiometabolic treatment. This patients have a 5-year survival rate of 50% and 10-year survival rate < 10%. 54 patients were recruited from January 2016 to May 2019. The patients were divided into two arms: first arm (experimental) includes all patients who underwent a second surgical look and possible therapy with Sorafenib. The second arm (control) includes patients who underwent only Sorafenib treatment. All the recruited patients were refractory to radiometabolic treatment with 131I. In 29 patients the complete follow-up of 18 months was possible; in the remaining 15 the follow up is still ongoing. The evaluation of the regression / stability or progression of the disease was evaluated using the American Thyroid Association's risk stratification. The morphological evaluation of the lesions was performed following the RECIST criteria. The data analysis showed that there is a statistically significant difference only between the PFS (Progression Free Survival) of the control arm and that of the experimental arm in favor of the experimental arm (p = 0.0399), but observing overall survival at 18 months there is no statistically significant difference (p = 0.197), but it's to be interpreted in the light of the temporal bias or the brevity of the study of only 18 months.File | Dimensione | Formato | |
