Survival time after CIN treatment is based on postoperative pathological staging and the presence or absence of infiltration. CIN3 is the highest grade of cervical intraepithelial lesions and is usually defined in the same way as cervical carcinoma in situ. If CIN3 is cured, it has no effect on long-term survival, so there is no question of how many years one can live after curing. However, if the postoperative pathology of cervical carcinoma in situ is reported as adenocarcinoma, or if the lesion has broken through the basal layer and interstitial infiltration is present, there is a possibility of postoperative recurrence. Generally speaking, if postoperative with standardized radiotherapy, patients without distant metastasis can survive for 10 years or longer, while if distant metastasis exists or the tumor is poorly differentiated pathologically, the survival may be 5 to 10 years. In addition, cervical conization or simple hysterectomy may be chosen for younger patients or those with fertility requirements, while hysterectomy is preferred for older patients or those without fertility requirements. Regardless of the surgical procedure, TCT and HPV should be followed closely after surgery.
