Study Details

Study Description

Brief Summary

Open-label randomized phase III trial, using a non-inferiority comparison design. After randomization,patients will receive either post-operative radioiodine ablation with an activity of 1.1 GBq (30 mCi) after stimulation by rhTSH, and then be followed-up (ablation group) or be followed-up (without postoperative radioiodine ablation) (follow-up group).

The objective is to assess the non-inferiority of the proportion of patients without tumor-related event evaluated at three years after randomisation in the absence of radioiodine ablation (follow-up group) compared to the ablation group, in patients with low-risk differentiated thyroid cancer treated with total thyroidectomy with or without lymph node dissection (pT1am N0 or Nx, pT1b N0 or Nx)

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Ablation group

Administration of 1.1 GBq of I131 is given after the second intramuscular injections of rhTSH (0.9 mg). A whole body scan (WBS) is performed 2 to 5 days after the administration or I131 with determination of the neck uptake. Follow-up consists in: 10 (+/- 2 months) after randomization: neck ultrasound + a serum Tg measurement after rhTSH stimulation 2 years (+/- 2 months) after randomization: serum Tg measurement under LT4 treatment (Tg/LT4) 3 years (+/- 2 months) after randomization: neck ultrasound and a serum Tg/LT4 4 years (+/- 2 months) after randomization: a serum Tg/LT4 5 years (+/- 2 months) after randomization: a neck ultrasound and a serum Tg/LT4

Drug: rhTSH stimulation
Intramuscular injections of rhTSH (0.9 mg) on two consecutive days on LT4 treatment
Other Names:
  • Thyrogen
  • Drug: I131
    An activity of 1.1 GBq of I131 is given orally 24 hours after the second injection of rhTSH.

    Other: Follow up
    10 (+/- 2 months) after randomization: a neck ultrasound and a serum Tg measurement after rhTSH or LT4 stimulation 2 years (+/- 2 months) after randomization: a serum Tg measurement under LT4 treatment (Tg/LT4) 3 years (+/- 2 months) after randomization: a neck ultrasound and a serum Tg/LT4 4 years (+/- 2 months) after randomization: a serum Tg/LT4 5 years (+/- 2 months) after randomization: a neck ultrasound and a serum Tg/LT4

    Experimental: Follow up group

    Patients randomized in the follow up group neither received 131I nor rhTSH. Patients will undergo the same followup procedures as patients randomized to the ablation group, except that at 10 months after randomization, Tg will be measured under LT4 treatment and not after rhTSH stimulation.

    Other: Follow up
    10 (+/- 2 months) after randomization: a neck ultrasound and a serum Tg measurement after rhTSH or LT4 stimulation 2 years (+/- 2 months) after randomization: a serum Tg measurement under LT4 treatment (Tg/LT4) 3 years (+/- 2 months) after randomization: a neck ultrasound and a serum Tg/LT4 4 years (+/- 2 months) after randomization: a serum Tg/LT4 5 years (+/- 2 months) after randomization: a neck ultrasound and a serum Tg/LT4

    Outcome Measures

    Primary Outcome Measures

    1. Rate of patient without event at 3 years following randomization [assessed up to 3 years]

    Secondary Outcome Measures

    1. Lachrymal and Salivary Glands Toxicities [Assessed up at baseline, 2 months, 10 months and 3 years after randomization]

    2. Patient's quality of life, anxiety and fear of recurrence [at inclusion, 2 months after inclusion, 10 months and 3 years after randomization]

    3. Rate of patients without event [at 5 years following randomization]

    4. Rate of events adjusted on the initial lymph node status [at 3 and 5 years following randomization]

    5. Recurrence rate (histologically proven) [at 3 years following randomization and then at 5 years]

    6. Rate of cure after an event [at 5 years after randomization]

    7. Cost of treatment and follow-up [at 3 years after randomization]

    8. Rate of events adjusted on tumoral molecular characterization [three and five years after randomization,]
