About

The first aim of this comparative, randomized, prospective, multicenter study is to evaluate the analgesic effect at 6 weeks of whole-body cryotherapy, compared to placebo cryotherapy, in patients suffering from arthralgia under aromatase inhibitor treatment for hormone-dependent breast cancer in adjuvant situation. The secondary objectives are to evaluate the tolerance of cryotherapy sessions and the evaluation of the impact of the cryotherapy sessions on the consumption of analgesics, the compliance of the treatment by anti-aromatases, the quality of life. The patient and investigator will be blinded to the treatment. Only the cryotherapist will have knowledge of the treatment group: * Whole Body Cryotherapy group (Arm A), or * Placebo Cryotherapy group (Arm B). Patients consulting for the follow-up of a breast cancer and presenting arthralgias under anti-aromatase will be included in the study after verification of the inclusion and non-inclusion criteria and collection of consent. The sessions will be performed according to the randomization arm as follows * Whole body cryotherapy group: 10 sessions will be performed daily, over a period of 12 to 21 days. For each session, the patient enters a chamber at -85°C for 4 minutes 30 seconds. * Placebo cryotherapy group: 10 sessions will be performed daily, over a period of 12 to 21 days. For each session, the patient enters a chamber at -85°C for 1 minute. Each patient will complete the BPI-SF and HAQ questionnaires 15 days +/- 7 days prior to the start of cryotherapy, at the 6 week, 3 and 6 month post-cryotherapy visit. Each patient will indicate the number of days of anti-aromatase therapy in the 6 months prior to inclusion and at 6 weeks, 3 and 6 months after cryotherapy. For this purpose, each patient will indicate the number of hormone therapy tablets taken in the 15 days prior to the inclusion visit, the 6 week, 3 and 6 month visit. Each patient will indicate the analgesic treatments used, classified in three categories: levels 1, 2 and 3 at the inclusion consultation and at 6 weeks, 3 and 6 months after cryotherapy (analgesics taken during the 15 days preceding the visit). The evaluation of the tolerance with the collection of the undesirable effects will be made before and at the end of each session by the professionals of the CryoMed. It will also be evaluated in the week following the end of cryotherapy during a telephone call.

Full description

In 2018, the number of new cases of breast invasive cancer in France was estimated to be over 58 500, with a median age at diagnosis of 63 years. The 5-year survival rate (as measured by age) has improved over time thanks to various treatments . Hormonotherapy is one of the disease's treatment options, and it includes a variety of molecules, including aromatase inhibitors. Despite their effectiveness, aromatase inhibitors cause a variety of side effects, including arthralgia in 35 percent to 50% of patients. The physiopathological mechanisms underlying these arthralgies would include articular inflammation, increased intra-articular fluid, and the appearance of a tenosynovitis. These side effects are frequently responsible for the premature discontinuation of hormone therapy and, as a result, the therapeutic effect of molecules. In order to improve the management of arthralgias caused by aromatase inhibitors, and because current recommendations are unclear, the effects of whole-body cryotherapy in patients who are taking an aromatase inhibitor for a hormono-dependent cancer in an adjuvant setting will be investigated. In fact, cryotherapy has already demonstrated its efficacy in the treatment of arthritic pain in a variety of diseases (rheumatoid arthritis,..). This is a category 1, comparative, randomized, prospective, multicenter study. The patient and investigator will be blinded to the treatment. Only the cryotherapist will have knowledge of the treatment group. Randomization will be performed after information and signature of informed consent on the day of the inclusion visit. Patients will be randomized to either either in the Whole Body Cryotherapy group (Arm A), or in the placebo Cryotherapy group (Arm B). Randomization will be stratified by center, initial BPI score of most severe pain (greater than or equal to 7 vs. less than 7) and duration of initial pain exposure (greater than or equal to 6 months vs. less than 6 months). It will be centralized, accessible online (on the Internet) and programmed by minimization using the Ennov Clinical software (CSRandomization module) by the Clinical Research Unit of the Medical Information Department (DIM) of the Montpellier University Hospital. Patients will be recruited from the gynecological consultation service of the Arnaud de Villeneuve Hospital in Montpellier and the Caremeau Hospital in Nîmes. Patients consulting for the follow-up of a breast cancer and presenting arthralgias under anti-aromatase will be included in the study after verification of the inclusion and non-inclusion criteria and collection of consent. Oral and written information will be given at the inclusion visit. Written consent will be collected at the end of the same visit after a reflection period. Prior to the cryotherapy sessions, the patient will be asked not to exercise, take a shower or take any stimulant (tea or coffee) before a cryotherapy session. Before the first cryotherapy session, after a new verification of the absence of contraindication to cryotherapy, a blood pressure and temperature measurement will be taken (questionnaire before/after cryotherapy). The patient will receive information on the course of a cryotherapy session and will then be prepared: protection of recent skin wounds, wearing of a bathing suit and a surgeon's mask, protection of the extremities by gloves, slippers and a polar cap provided by the CryoMed. Before each of the following sessions, a blood pressure reading and a skin temperature reading between the Achilles heel and the triceps will be taken. The occurrence of undesirable events since the last session will be investigated (questionnaire before/after cryotherapy). After the patient enters the cryotherapy chamber (CryoAir, MecoTec), a permanent visual contact is kept on the patient throughout the session, thanks to a glass window. It is also possible to hear and communicate with the patient throughout the session. The sessions will be performed according to the randomization arm as follows Whole body cryotherapy group: 10 sessions will be performed daily, over a period of 12 to 21 days. For each session, the patient enters a chamber at -85°C for 4 minutes 30 seconds. Placebo cryotherapy group: 10 sessions will be performed daily, over a period of 12 to 21 days. For each session, the patient enters a chamber at -85°C for 1 minute. Patients can stop the cryotherapy session at any time. The duration of each session will be noted on the Before-After Cryotherapy questionnaire. Finally, after the cyrotherapy sessions: Whole body cryotherapy group: In order to better understand the thermal shock and to adjust the following sessions, the patient's temperature will be recorded between her Achilles tendon and her triceps, as soon as she leaves the cryotherapy chamber: If > 12°C, the duration of exposure to -85°C will be increased by 20 seconds during the following sessions. If < 5°C, the duration of exposure to -85°C will be decreased by 20 seconds during the following sessions. This process will be repeated with each new cryotherapy session. • Placebo Cryotherapy Group: In order to promote blindness, the patient's temperature will be recorded between her Achilles tendon and her triceps, as soon as she leaves the cryotherapy chamber, but no change will be made to the duration of the following sessions. Adverse events will be investigated at the end of each session (before/after cryotherapy questionnaire). Each patient will complete the BPI-SF and HAQ questionnaires 15 days +/- 7 days prior to the start of cryotherapy, at the 6 week, 3 and 6 month post-cryotherapy visit. Each patient will indicate the number of days of anti-aromatase therapy in the 6 months prior to inclusion and at 6 weeks, 3 and 6 months after cryotherapy. For this purpose, each patient will indicate the number of hormone therapy tablets taken in the 15 days prior to the inclusion visit, the 6 week, 3 and 6 month visit. A calendar will be given to each patient: the patient will indicate the use of hormone therapy and analgesics during the 15 days preceding the visits. Each patient will indicate the analgesic treatments used, classified in three categories: levels 1, 2 and 3 at the inclusion consultation and at 6 weeks, 3 and 6 months after cryotherapy (analgesics taken during the 15 days preceding the visit). The evaluation of the tolerance with the collection of the undesirable effects will be made before and at the end of each session by the professionals of the CryoMed. It will also be evaluated in the week following the end of cryotherapy during a telephone call. A difference of 2 points or more in the BPI-SF score is considered as clinically significant. Under this assumption and that of a standard deviation of 2.3 points in both groups, the number of subjects to be analyzed to demonstrate a difference between the groups, with a two-sided alpha risk of 5% and a power of 80%, is 42 subjects, i.e. 21 subjects per group. In this study, there is a risk of attrition during or after the sessions, evaluated at 20%, and a risk of attrition of 20% between inclusion and the first session, due to organizational constraints and the possible appearance of contraindications to cryotherapy. In case of attrition between the inclusion and the first session, for a provisional reason, the patients could be re-included. A total of 70 inclusions are finally possible. As soon as 56 patients (28 per group) have completed at least one session, recruitment can be stopped. The threshold of significance is set at 0.05 bilaterally for all analyses. Qualitative variables will be described by their number and percentage. Quantitative variables will be described by their mean, standard deviation, extrema, median and quartiles, in the randomized population, in the ITT population, in the PP population, in the safety population, and in each of the two groups within each of these populations. In addition, all baseline variables will be described in the included population. A flow-chart will be performed. The main analysis will be performed in the ITT population by comparing the mean of the primary endpoint (most severe pain at 6 weeks) between the two groups by a test appropriate to the distribution of the data. Missing data will not be imputed. The primary analysis will be supplemented by a secondary analysis of the YAC in which missing data will be imputed by multiple imputation, in the randomized population, and by an analysis in the PP population. Secondary endpoints will be compared between the two groups, in the ITT population and in the PP population, without imputation for missing data: Mean comparisons for Most severe pain at 3 and 6 months BPI-SF composite pain severity and interference scores at 6 weeks, 3 and 6 months. Health Assessment Questionnaire (HAQ) scores at 6 weeks, 3 and 6 months Number of days on anti-aromatase therapy at 6 weeks, 3 and 6 months after cryotherapy. Comparison of percentages for the use of the different levels of analgesics at 6 weeks, 3 and 6 months. Adverse events will be compared between the two groups in the safety population.
