nFive randomized phase III trials have shown an overall survival advantage for cisplatin-based therapy given concurrently with radiation therapy,1-6 while 1 trial examining this regimen demonstrated no benefit.7nThe risk of death from cervical cancer was decreased by 30%to 50%by concurrent chemoradiation.nBased on these results,strong consideration should be given to the incorporation of concurrent cisplatin-based chemotherapy with radiation therapy in women who require radiation therapy for treatment of cervical cancer.1-89/12/2024Dr.Xiaohua Wu 7Treatment Option OverviewnSurgery and radiation therapy are equally effective for early-stage small-volume disease.9 nYounger patients may benefit from surgery in regard to ovarian preservation and avoidance of vaginal atrophy and stenosis.nPatterns of care studies clearly demonstrate the negative prognostic effect of increasing tumor volume.nTherefore,treatment may vary within each stage as currently defined by FIGO,and will depend on tumor bulk and spread pattern.10 9/12/2024Dr.Xiaohua Wu 8Treatment Option OverviewnTherapy of patients with cancer of the cervical stump is effective,yielding results comparable to those seen in patients with an intact uterus.11 nDuring pregnancy,no therapy is warranted for preinvasive lesions of the cervix,including carcinoma in situ,although expert colposcopy is recommended to exclude invasive cancer.nTreatment of invasive cervical cancer during pregnancy depends on the stage of the cancer and gestational age at diagnosis.9/12/2024Dr.Xiaohua Wu

there is little evidence to demonstrate overall improved survival with routine surgical staging,it usually should be performed only as part of a clinical trial.nPretreatment surgical staging in bulky,but locally curable,disease may be indicated in select cases when a nonsurgical search for metastatic disease is negative.nIf abnormal nodes are detected by CT scan or lymphangiography,fine needle aspiration should be negative before a surgical staging procedure is performed.9/12/2024Dr.Xiaohua Wu 14腹主动脉旁淋巴结腹主动脉旁淋巴结CT阴性患者中生存率曲线与阴性患者中生存率曲线与PET扫描结果的关系扫描结果的关系 J Clin Oncol

procedure(LEEP).7,8 nLaser therapy.9 nConization.nCryotherapy.10 nWhen the endocervical canal is involved,laser or cold-knife conization may be used for selected patients to preserve the uterus and avoid radiation therapy and/or more extensive surgery.nTotal abdominal or vaginal hysterectomy is an accepted therapy for the postreproductive age group and is particularly indicated when the neoplastic process extends to the inner cone margin.nFor medically inoperable patients,a single intracavitary insertion with tandem and ovoids for 5,000 milligram hours(8,000 cGy vaginal surface dose)may be used.11 9/12/2024Dr.Xiaohua Wu 19对异常对异常Pap 涂片或活检示涂片或活检示微小浸润癌微小浸润癌处理步骤处理步骤

IA Cervical Cancer Equivalent treatment options:nIntracavitary radiation alone:nIf the depth of invasion is less than 3 millimeters and no capillary lymphatic space invasion is noted,the frequency of lymph node involvement is sufficiently low that external beam radiation is not required.n One or 2 insertions with tandem and ovoids for 6,500 to 8,000 milligram hours(10,000-12,500 cGy vaginal surface dose)are recommended.4 nRadiation should be reserved for women who are not surgical candidates.9/12/2024Dr.Xiaohua Wu 21IB 和早和早
