Summary
Papillary cancer may affect patients of any age,with a good prognosis. Most of young patients may hence procreate as often as the general population.131iodine is an essential tool during treatment of thyroid cancer. According literature data, 131iodine given patients may experience exocrine testicular dysfunction with transient azoospermia, as a significant growing number of Desoxyribonucleic acid (DNA) damage may concern the patient or his offspring. The primary purpose will be to study a genomic instability within the germinal line, based on a significant mutation rate analysis in their minisatellites regions after 100 mCi 131 iodine irradiation compared to the baseline spermogram of each patient, thus being his own control case in a cross-over study.The inclusion of 50 patients treated by surgery prior to131iodine would result in statistically significant results.This multicentric cross-over study with a multidisciplinary approach will act for a direct benefit on testis function in patients aged 18-45 treated by 131iodine for thyroid cancer. Samples measurements timing will be: after surgery, 2 and 12 months after 131iodine administration.
