Study Details

Study Description

Brief Summary

Study on the carcinogenesis of Gα12 in oral cancer, and chemopreventive possibility for the treatment of oral cancer using Ga12 inhibitor.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    To find out if there is prognostic value which to the performance of Gα12 of oral cancer in Taiwan and provide some reference for future treatment.

    We anticipate to enroll 40 persons with normal oral mucosa, 65 persons with oral dysplasia and 150 persons with oral cancer and collect the tissue which was stained for pathological sections over a 3 year period.

    We also collect the blood and saliva samples from patients and the results along with patient-specific information such as tumor phases, tumor size, lymph node metastasis, cancer metastasis, prognosis and betel nut chewing, smoking and drinking habits and other parameters are statistically analyzed.

    Arms and Interventions

    Arm Intervention/Treatment
    Normal team

    Subjects who have problem at third molar of impacted tooth need to receive a surgery with general anesthesia. Subjects must: Should have a blood exam (20ml) before the surgery. Site staff must: Collect subjects' saliva once a day (in the morning before breakfast) for 3 consecutive days. Collect a 0.5x0.5Cm2 tissue sample around third molar during the surgery.

    Oral dysplasia

    Subjects who are diagnosed with dysplasia of oral cavity. Subjects must: Should have a blood exam (20ml/each time) before the surgery and 3 months after the surgery. In the case the disease recurs after the surgery, subjects need to receive the surgery again and take another blood exam before the surgery and 3 months after the surgery. Before the surgery site staff must: Collect subjects' saliva once a day (in the morning before breakfast) for 3 consecutive days. Collect a 0.5x0.5Cm2 tissue sample of the tumor during the surgery.

    Oral cancer

    Subjects who suffer from oral cancer. Subjects must: Should have a blood exam (20ml/each time) before the surgery and 3 months after the surgery. In the case the disease recurs after the surgery, subjects need to receive the surgery again and take another blood exam before the surgery and 3 months after the surgery. Before the surgery site staff must: Collect subjects' saliva once a day (in the morning before breakfast) for 3 consecutive days. Collect a 0.5x0.5Cm2 tissue sample of the tumor during the surgery.
