Oksifilni karcinomi čine 3 do 5% svih karcinoma štitaste žlezde, i smatraju se retkim
tumorima.
Cilj: Cilj ove teze je bio da se analiziraju kliničke karakteristike i stope preživljavanja kod
pacijenata sa oksifilnim karcinomom štitaste žlezde.
Materijal i metod rada: Sakupljeni su podaci o demografskim karakteristikama, gradusu
tumora, tipu hirurškog lečenja i vitalnom statusu pacijenata. Za statističku obradu su
korišćene metode desktiptivne statistike i Kaplan Majerove krive preživljavanja. Koksova
proporcionalna regresija je korišćena za identifikaciju nezavisnih prediktora preživljavanja.
Rezulati: Tokom period od 1995 do 2014. godine, 239 pacijenata je operisana zbog oksifilnog
karcinoma štitaste žlezde u Centru za endokrinu hirurgiju. Prosečna starost pacijenata je
iznosila 54,3 godine, sa odnosom žena prema muškacima od 3,6:1. Prosečna veličina tumora
je bila 41,8 mm. Ukupan je bilo 12,1% sa recidivantnom bolešću, sa prosečnim vremenom do
pojave recidiva od 90,74 meseci, i pros...ečnim vremenom bez znakova bolesti od 222,4 meseci.
Ukupno preživljavanje nakon 5, 10 i 20 godina je iznosilo redom 89,4%, 77,2% i 61,9%.
Specifično preživljavanje u odnosu na karcinom je nakon 5, 10 i 20 godina je iznosilo redom
94,6%, 92,5% i 87,4%. Preživljavanje bez znakova bolesti je nakon 5, 10 i 20 godina iznosilo
redom 91,1%, 86,2% i 68,5%. Zahvaćenost oba lobusa štitaste žlezde i potreba za reopracijom
zbog lokalnog recidiva su bili negativni prediktivni faktori za specifično preživljavanje u
odnosu na bolest, od je totalna tiroidektomija kao procedura na prvoj operaciji bila pozitivan
prediktivni faktor.Zaključak: Oksifilni karcinomi su retki tumori, sa dobrom prognozom, i nakon adekvatnog
hirurškog lečenja recidivi bolesti su retki.
Introduction: Oxyphile carcinoma makes up 3 to 5% of all thyroid cancers and is considered
to be a true rarity.
Aim: The aim of our study was to analyze clinical characteristics and survival rates of patients
with oxyphile carcinoma.
Material and methods: Clinical data regarding basic demographic characteristics, tumor
grade, type of surgical treatment and vital status were collected. Methods of descriptive
statistics and Kaplan-Meier survival curves were used for statistical analysis. Cox
proportional hazards regression was used to identify independent predictors.
Results: During the period from 1995 to 2014, 239 patients with oxyphile carcinoma were
treated at Center for Endocrine Surgery. The average age of the patients was 54.3, with
female to male ratio of 3.6:1 and average tumor size was 41.8 mm. The overall recurrence rate
was 12.1%, with average time for relapse of 90.74 months and average time without any signs
of the disease of 222.4 months. Overall 5-year, 10-year and 20-yea...r survival rates were
89.4%, 77.2%, 61.9% respectively. The 5-year, 10-year and 20-year cancer specific survival
rates were 94.6%, 92.5%, 87.4%, respectively. When disease free interval was observed, 5-
year, 10-year and 20-year rates were 91.1%, 86.2%, 68.5%, respectively. The affection of
both thyroid lobes and the need for reoperation due to local relapse were unfavorable
independent prognostic factors, while total thyroidectomy as primary procedure was favorable
predictive factor for cancer specific survival.
Conclusion: Oxyphile carcinoma is a rare tumor with an encouraging prognosis and after
adequate surgical treatment recurrences are rare.
