NOVE TEHNIKE U RADIOTERAPIJI KARCINOMA ŠTITNE ŽLIJEZDE
NEW RADIOTHERAPY TECHNIQUES FOR THYROID CARCINOMA

Summary/Abstract: Aim: To discuss new technologies in radiotherapy treatment for thyroid carcinoma. Traditional radiotherapy for thyroid carcinoma has certain restrictions because spinal medulla is close to the tumor. The radiotherapy dose must therefore be reduced in order to prevent the damage to this structure. Introducing Intensity modulated radiotherapy (IMRT), Image guided radiotherapy (IGRT) or tomotherapy can improve target coverage in cases that are difficult to treat. Patients and methods: According to the hospital malignant diseases register of Clinical Center of Sarajevo University (UKCS) there were 149 patients diagnosed with thyroid cancer and treated in this institution from 2009 to 2013. Retrospective analysis of data from Oncology Clinic during this period showed that 18 patients were treated at the Oncology Clinic of UKCS. Results: Most patients treated at the Oncology Clinic received palliative treatment, and only one patient received curative treatment. 16 patients had metastatic disease at the time of presentation for treatment, and one developed metastases after our treatment. One patient currently shows no signs of disease. Conclusion: In most cases radiotherapy is reserved for palliative treatments, due to the dosage restrictions. New techniques such as IMRT, IGRT and/or tomotherapy have demonstrated efficacy in precise treatment for tumors and also an increase in disease control, while at the same time ensuring a better protection of organs at risk from exposure to unnecessary radiation and thereby reducing long-term toxicity. For these reasons, new techniques may be considered a viable option in the treatment for thyroid cancer.
