About this study
The purpose of this study is to investigate the relationship between prognosis and fine needle aspiration cytology character of papillary thyroid cancer.
Read the detailed description
Papillary thyroid carcinoma is the most common thyroid malignancy worldwide. The influence of clinicopathologic features on prognosis has been examined, but the relationship between cytologic features obtained by fine-needle aspiration (FNA) and prognosis has been minimally studied. We retrospectively studied the cytologic features with computerized morphometry in 83 patients with usual-type papillary thyroid cancer and followed them for more than 10 years except for one with metastasis at diagnosis. The cytologic features of FNA and recurrence of cancer were examined statistically.

Questions about this trial
What is this clinical trial studying?
An observational study of Thyroid Neoplasms, run by National Taiwan University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Apr 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Apr 2007.
