The treatment of cervical cancer is mainly surgery and radiation therapy. Especially squamous carcinoma is more sensitive to radiation therapy. With the rapid development of anti-cancer chemical drugs in recent years, chemotherapy, which was considered ineffective for cervical cancer in the past, has become a common method of adjuvant treatment, especially in advanced or recurrent cases. If chemotherapy is used before surgery or radiotherapy, and after chemotherapy, surgery or radiotherapy is performed after the cancer foci have shrunk or partially shrunk, or chemotherapy is added after surgery or chemotherapy, the efficacy can be improved. Principles of treatment in different periods 1.Atypical hyperplasia If the biopsy is mild atypical hyperplasia, it should be treated as inflammation for the time being and followed up by scraping and biopsy in half a year if necessary. Those with persistent lesions can continue to be observed. For those diagnosed with moderate atypical hyperplasia, laser, freezing and electro-ironing should be applied. For severe atypical hyperplasia, total hysterectomy is generally advocated. If there is an urgent need for fertility, close follow-up can be performed regularly after conical resection. 2.Carcinoma in situ Generally, total hysterectomy with bilateral ovaries preserved is advocated; some advocate simultaneous removal of 1~2 cm of vagina. 3.Microscopic early infiltrating carcinoma Generally, enlarged total hysterectomy and 1~2cm of vaginal tissue are advocated. Because the possibility of lymphatic metastasis of microscopic early infiltrating cancer is very small, it is not necessary to eliminate pelvic lymphatic tissue. 4.Infiltrating carcinoma Treatment methods should be based on clinical stage, age and general condition, and equipment conditions. Commonly used treatment methods include radiation, surgery and chemotherapy. Generally speaking, radiotherapy can be applied to patients of all stages; the efficacy of surgery is similar to radiotherapy for stages Ib to IIa; cervical adenocarcinoma is slightly less sensitive to radiotherapy and should be treated by a combination of surgical resection plus radiotherapy. Main treatment methods 1.Surgical treatment Extensive hysterectomy and pelvic lymph node elimination are used. The scope of resection includes the whole uterus, bilateral adnexa, upper vagina and paravaginal tissues as well as the lymph nodes in the pelvic cavity (paracervical, foramen ovale, internal iliac, external iliac and inferior common iliac lymph nodes). The operation requires thoroughness, safety, strict control of indications and prevention of complications. Radiation therapy is the first choice for cervical cancer and can be applied to all stages of cervical cancer. The scope of radiation includes the cervix and the affected vagina, uterine body, parametrium and pelvic lymph nodes. 3.Chemotherapy So far, cervical cancer is not sensitive to most anti-cancer drugs, and the efficiency of chemotherapy does not exceed 15%. Chemotherapy can be administered intravenously or locally by 5-fluorouracil, adriamycin, etc.
