Active clinical trials for "Thyroid Cancer, Papillary"

BRAFV600E is the most frequent oncogene in Papillary thyroid carcinoma (PTC). It correlates with greater extension, lymph node metastasis, and advanced stage. However, the prognostic value of BRAFV600Eis weak and the search of this mutation is not recommended in clinical management of thyroid cancer. PTC are characterized by intratumor heterogeneity with wild-type and BRAFV600E tumoral cells. In a previous study, the BRAFV600E/BRAFwild-type ratio correlated with patient age, tumor volume, lymph node metastasis and with worst disease outcome. While the existence of intratumor heterogeneity in PTC is supported by many evidences, its extension, biological significance and clinical utility is questioned and must be further investigated. Primary endpoint of the study is to determine the relationship between the percentage of BRAFV600E alleles and outcome in PTC patients. Secondary endpoints are to determine the mean and median BRAFV600E/BRAFwild-type allele ratio in heterogeneous tumors; determine the relationship between the percentage of BRAFV600E alleles and clinicopathological features. The study protocol entails the assessment by digital-droplet PCR the BRAFV600E/BRAFwild-type allele ratio in a series of PTC and its correlation with clinicopathology features and outcome.

Papillary thyroid microcarcinoma are small thyroid cancer measuring 1cm or less. Most of this tumor are not palpable and are identified either through pathologic examination or from imaging modalities, such as CT scan or thyroid sono. Active surveillance of papillary microcarcinoma is to observe thyroid papillary cancer without immediate surgical approach. The purpose of this study is to understand more about the characteristics of papillary microcarcinoma, which has been known for "the cancer slowly progression"

In the last decades, thyroid cancer incidence has continuously increased all over the world, almost exclusively due to a sharp rise in the incidence of the papillary histologic subtype, which has the highest incidence of multifocality. Furthermore, Black Sea and Eastern European regions are both endemic and known to have been under the influence of Chernobyl nuclear explosion. Although overscreening might have a role in certain parts of the world, the predictors of malignancy such as family history, genetical disorders, previous radiation exposure, low iodine intake, diabetes and obesity, should also be taken into consideration in determining the extent of surgery.
