[Global guidelines for cervical cancer and precancerous lesions treatment: a systematic review]

Objective: To systematically summarize current status and recommendations of the global cervical cancer and precancerous lesions treatment guidelines. Methods: The retrieval for all the Chinese and English literature published before July 8, 2021 was conducted in PubMed, Embase, SinoMed Database, CNKI and Wanfang Database, supplemented by a search of health websites of countries worldwide, with"uterine cervical neoplasms""cervix cancer""cervical neoplasm""cervical precancerous lesions""treat*""guideline*""practice guideline*""consensus" "recommendation*""guidebook*"in English as well as"cervical precancerous lesions""cervical neoplasm""treatment""guideline*""consensus"in Chinese as search keywords. A total of 38 guidelines were included for data extraction and analysis. Results: Guidelines covered Asia, Europe, North America, South America and Oceania. Conservative observation was recommended for the CIN1 population. For the women with CIN2/CIN3, ablation or excision was recommended according to the specific situation and guidelines of developed countries give priority to the latter. In low and middle resource countries, given the availability of medical resources, ablative treatment was recommended as an alternative to excisional treatment if the women were eligible. For women with adenocarcinoma in situ (AIS), cervical conization or total hysterectomy was recommended depending on the patient's desire of fertility. For patients with cervical cancer, most guidelines recommended surgery for early disease and smaller lesions, otherwise concurrent chemoradiotherapy was usually the main treatment modality for advanced cancers. All guidelines recommended long-term follow-up to monitor disease recurrence after treatment. Follow-up methods included human papillomavirus (HPV) testing and/or cytology or colposcopy. Most guidelines recommended follow-up at 6 or 12 months after treatment for cervical precancerous lesions, and 3~4 months for cervical cancer. Conclusions: There are some differences in the treatment and management recommendations for cervical cancer and precancerous lesions issued by different countries and regions around the world. Based on the global treatment guidelines and medical resource of different regions, the treatment and management guidelines for cervical cancer and precancerous lesions suitable for different regions of China should be developed, so as to achieve effective treatment.
