Read the detailed description
Cervical cancer is the seventh most common malignancy and the sixth most common cause of cancer-related death in Taiwan. The development of cervical cancer is passed through cervical intraepithelial neoplasia (CIN), including CIN I, CIN II, and CIN III. CIN I is classified as low-grade squamous intraepithelial lesion (LSIL), and about 57% of patients with CIN I are known to regress spontaneously, while patients with CIN II or CIN III is 5% and 15% to progress to invasive cervical cancer, respectively. Both two need active treatment and are classified as high-grade squamous intraepithelial lesion (HSIL). Fortunately, the 5-year survival rate is more than 90% for patients with CINs if they receive clinical management as soon as possible. The immunocompetence plays an important role for prevention of cervical cancer. High-risk human papillomavirus (HR-HPV) infection is demonstrated as one of the vital risk factors of CIN and cervical cancer. Most HPV infection is known to regress spontaneously by cell-mediated immunity, whereas a small fraction persistant HPV infection, which increase the risk of CIN and promote the progression to cervical cancer. Physical activity is reported to increase the cell number and activity of immune cells and promote cell-mediated cytotoxic effect to protect against HPV and cancer cells. Also, it is found that physical activity decrease the risk of breast cancer, hepatocellular carcinoma, colon cancer, and prostate cancer. Regular moderate intensity physical activity is ssociated with a decrease in the death from cancer. Moreover, tobacco smoke is reported to abate human immunocompetence and raise the risk of cervical cancer as well as to enhance the progression of CIN through the inhibition of cell-mediated immunity. Also, the extract of tobacco is demonstrated to enhance the proliferation and viral load of HPV, consequently induce carcinogenesis of cervical intraepithelial cells. Investigators suggest that physical activity could decrease the risk of CIN through promote cell-mediated immunity. Also, physical activity and abstain from smoking could be benefit to the regression of CIN and the decreasing of DNA viral load of HPV. However, the roles of physical activity and abstain from smoking on the regression of CIN and viral load are not fully clarified. Therefore, in this proposed project, investigators will 【1】estimate the effect of physical activity on decreasing the risk of cervical intraepithelial neoplasia. 【2】estimate the effect of physical activity on the regression of cervical intraepithelial neoplasia. 【3】estimate the effect of abstain from smoking on the regression of cervical intraepithelial neoplasia. 【4】estimate the additive effect and synergistic effect of physical activity and abstain from smoking on the regression of cervical intraepithelial neoplasia. 【5】estimate the effect of physical activity on the decreasing of DNA viral load of human papillomavirus. 【6】estimate the effect of abstain from smoking on the decreasing of DNA viral load of human papillomavirus. 【7】estimate the additive effect and synergistic effect of physical activity and abstain from smoking on the decreasing of DNA viral load of human papillomavirus

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Physical activityBehavioural
In physical activity experimental group, trained study nurses will interview with patients,give health education,teach how to use and record the Activity meter.Professionals will calculate Metabolic Equivalent of Task(MET) with formula weekly.MET = (intensity level 9 points * time of each exercise (hours) * Number of times per week + moderate level 5 points * time per activity (hours) * number of times per week + low level 3 points * time per activity (hours) * number of times per week),investigators hope patients in the first month MET can reach (3.75-7.49 MET-h/ week), and reach moderate or more than moderate activity (>= 7.5-16.49 MET-h/ week) at the starting of second month for at least one year.

What is being measured
The primary outcome is the main question the study is designed to answer.
The effect of physical activity and abstain from smoking on the regression of precancerous
To estimate the effect of moderate physical activity and abstain from smoking can strengthen the innate immune system,adaptive human immune system and can help regression of Cervical intraepithelial neoplasia among patients with cervical cancer.
Using a composite outcome measure consisting of questionnaire,blood counts,plasma and DNA.

Questions about this trial
What is this clinical trial studying?
A study testing Physical activity in people with Cancer Cervix Uterus and Precancerous Lesions, run by Taipei Medical University at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 11 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yu-Wen Su, Bs (0917562397, m432104011@tmu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The effect of physical activity and abstain from smoking on the regression of precancerous (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03093623, which also lists 69 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2017.
