Brief Summary

Osteoid osteoma (OO) is a benign osteogenic tumor occurring in children and young adults, responsible for intense bone pain, which has a tendency to spontaneously heal with mineralization of the nidus, but extremely slowly. This healing may be accelerated in patients taking NSAIDs regularly during a few years. The long delay for healing and intense pain, explain why patients are quickly directed to surgeons or specialized radiology departments for tumor ablation. But percutaneous treatment or surgical excision destruction can expose the patient to a substantial risk in terms of neurologic or joint damages, depending on the location. Bisphosphonates treatment may be an effective alternative to percutaneous treatment by accelerating the natural history of OO.

Detailed Description

Osteoid osteomas (OOs) are small, benign but painful bone tumors, mainly observed in children and young adults. Pain, almost universal, is characteristically greater at night. Pain is well relieved by NSAIDs but resolution is not always complete and pain reappears a few hours after the last dose. Also long-term consumption of NSAID can lead to serious adverse events. Therefore OOs are usually cured shortly after diagnosis, mainly by means of percutaneous treatment (PT) under computed tomography (CT) (radiofrequency coagulation or interstitial laser ablation).

The clinical success rate using these techniques is 96% at 6-month, 94% at 24-month. However, the technique is not distributed everywhere since it is performed by highly specialized interventional radiologists. The PT is performed under general, spinal or regional anesthesia. General anesthesia is used in most cases, especially in children. When the OO is located in close proximity to the skin, cartilage, vessels and nerves, severe complications may occur and additional procedures such as infusion of saline or injection of CO2 at the interface between the OO and the vulnerable structure are done. Also few anatomic locations are not accessible to a PT.

The natural history of OOs remains poorly understood. However investigators in small series of conservatively treated OOs suggested a spontaneous healing of the lesion with mineralization of the nidus and resolution of pain (mean duration of pain in patients with NSAID treatment: 33 months NSAID).

The efficacy of bisphosphonates on pain related to benign (Langherhans cell histiocytosis, fibrous dysplasia, Paget disease) or malignant bone lesions has been widely reported. The investigators observed such efficacy in a small series of 20 patients with percutaneously hard-to-reach or recurrent OO using one to three infusions of zoledronate. The clinical efficacy assessed on pain relief was accompanied by a significantly increased mineralization of the nidus. The investigators postulated that bisphosphonates had accelerated the natural history of OO.

Our hypothesis is that three infusions of zoledronate (4mg) repeated monthly in patients with symptomatic OO is non-inferior to percutaneous treatment on the efficacy, measured by pain relief at Visual Analogical Scale (VAS).

The main objective of this randomized study is to demonstrate that in patients with OO, treatment with three intravenous cycles of 4mg of zoledronic acid administered monthly, is non-inferior to treatment with percutaneous thermal ablation on the efficacy measured by the percentage of pain relief between baseline and end of treatment.

NB: Patients for whom the OO would not be percutaneously accessible (that is to say when the percutaneous treatment or surgical excision destruction expose the patient to a substantial risk in terms of neurologic or joint damages) will be offered to participate in a cohort, only in Lariboisière and Cochin hospital in Paris. In the cohort, the clinical follow-up will be conducted as it is currently proposed in Laribosisière hospital (no act added by the research). Objectives of the register will be explained to the patient. It consists in collecting anonymized medical data after a bisphosphonate treatment to statuate on the efficacy of the bisphosphonates to relieve pain due to osteoid osteoma.

Study design of the randomized study:

• Selection / Inclusion visit: verification of eligibility, randomization and recollection of patient consent.
• Intervention:

• percutaneous thermal ablation at V1 visit (i.e. maximum one month after the selection / inclusion visit)
• or three zoledronic acid infusions at V1, V2 (one month after v1) and V3 visits (one month after V2)
• V4 visit at 4 months (end of treatment, evaluation of the main outcome) and V7 visit at 16 months (end of study, evaluation of the secondary outcomes).
• Option: One to 3 additional visits (V4, V5 and V6) for zoledronic acid infusion can be proposed to the patient, depending on the efficacy of the previous infusion.

Study Groups

1: Percutaneous treatment

Percutaneous treatment of OO is a thermal tumor destruction by radiofrequency or laser photocoagulation performed under CT control with strict aseptic approach and most often under general anesthesia. The introductive needle is inserted toward the nidus. Then the optic fiber or the radiofrequency probe is inserted in the nidus center and thermal destruction of the tumor is obtained.When the distance between the nidus and a nerve or the skin is less than 10 mm, infusion of normal saline or CO2 is introduced as spacing agent. When the nidus is in the subchondral bone, cold normal saline is introduced in the joint to protect the cartilage. In addition, a thermocouple is placed in the epidural or foraminal space to continuously monitor the temperature. A procedure typically required between 1 and 2 h from the time the patient entered the CT unit.

2: Bisphosphonate treatment

The treatment consists of 3 infusions of zoledronic acid administered at a monthly interval. Bisphosphonate treatment is considered finished 1 month after the third bisphosphonate infusion (V4 visit). In few cases, the analgesic efficacy provided by 3 bisphosphonate infusions cannot be sufficient: 1 to 3 additional infusions could be proposed to the patient.

Zoledronic acid is supplied as a 4 mg/100 ml solution for infusion. It will be administered as infusion over 30 minutes under the supervision of a nurse. Adults will receive intravenous infusion of 4 mg of zoledronic acid. Children will receive infusion of 0.025 mg/kg of zoledronic acid.

The investigators propose abacus corresponding to zoledronic acid volume to infuse during 30 minutes for children.
