The TMS Treatment for Postoperative Headache in GH Tumor

Study Purpose

Headache is a very common main complaint of patients with GH pituitary tumor, which has seriously affected the normal work and life of patients. Although the current surgery and drugs have a certain effect on patients with headache, the overall effect is not satisfied. However, the use of COX-2 inhibitors, non-steroidal anti-inflammatory drugs and other analgesics are only effective for some patients with headaches, and long-term use has adverse reactions. Therefore, it is necessary to seek new treatments for postoperative headaches in patients with GH pituitary tumors. Transcranial magnetic stimulation (TMS) modulates the excitability of the underlying cerebral cortex by applying a rapidly changing magnetic field on the surface of the scalp. It is a relatively simple and safe method. It is currently approved for treating depression, migraine, obsessive-compulsive disorder, and Alzheimer's disease. Several small clinical studies have proven that rTMS can be used to prevent and treat Headache. Therefore, this study aims to observe the efficacy and safety of TMS in the treatment of postoperative headache in patients with GH pituitary tumors.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Yes
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 60 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients with GH tumor who have undergone transnasal pituitary tumor resection or craniotomy for pituitary tumor resection in the past (3 months or more), aged between 18 and 60 years old, regardless of gender; - Preoperative glucose tolerance test (OGTT) simultaneously determines that the trough value of GH is greater than 1ng/ml, and the level of IGF-1 is greater than the upper limit of the age-sex-matched normal value; ③.

Biochemical remission is achieved after surgery, that is, the random GH value is less than 1ng/ml, and the IGF-1 level is within the normal range of age and gender matching; ④. The patient still has headaches after the operation, the duration of each attack is more than 4 hours, and the attack is more than 3 times per month; ⑤. The patient is in a headache attack period; ⑥. A clear consciousness, able to understand and sign an informed consent form.

Exclusion Criteria:

- Patients who are being treated with somatostatin and bromocriptine; - Patients with other intracranial organic diseases; - Pregnant women and children who cannot express; - Patients with other malignant tumors; - Participate in other clinical research in the same period; ⑥.

- Those with mental illness who cannot cooperate well with the experiment; - Patients with acute infection or open wounds; ⑨.

Acetaminophen is contraindicated (hemolytic anemia, severe liver and kidney dysfunction) or allergic to its components; ⑩. Patients with contraindications to transcranial magnetic stimulation: patients or users who have implanted cardiac pacemakers, implantable defibrillators and neurostimulators together; those who have a history of epilepsy; wear electronic products (such as insulin Pumps, Holter, etc.).

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04529356
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Arms & Interventions

Arms

Sham Comparator: Simple acetaminophen treatment

Acetaminophen will be taken when patients suffered from headache during the study. No specific dosage and frequency was required for this group as long as the participants record the exact drug usage.

Active Comparator: Simple acetaminophen combined with low-frequency rTMS

Apart from acetaminophen usage, low frequency TMS (1HZ) will be used in patients three times a month for 6 months.

Experimental: Simple acetaminophen combined with high-frequency rTMS

Apart from acetaminophen usage, high frequency TMS (10HZ) will be used in patients three times a month for 6 months.

Interventions

Device: - Transcranial magnetic stimulation

By using different frequency of TMS, the device can generate different effects. For low frequency, such as 1HZ, it mainly generates inhibition on the brain cortex; while high frequency (usually higher than 10HZ) can generate stimulation effects. The later one could be used to treat different central nervous disease.

Drug: - Acetaminophen

Acetaminophen is used as the painkiller to alleviate patients' headache before and during the clinical trial. In order to decrease the medication bias, we required these patients to only use acetaminophen instead of other non-steroid anti-inflammatory drugs. In the meantime, participants are requested to recorder the frequency and dosage of acetaminophen they used during the treatment course.
