What are stages of cervical cancer
Point B is also a 2 cm from the external os and 5 cm lateral to the midline of the patient, relative to the hipbone. In general, for small tumors, the curative dose to the point a is about 70 Gy, whereas for tumors larger than the point of a dose can approach 90 gy. Although the positive trials vary somewhat depending on the stage of the disease, the dose of radiation and cisplatin schedule and radiation, the trials demonstrate significant survival benefit for this combined approach. HDR brachytherapy provides the advantage of eliminating radiation exposure to medical personnel, a shorter treatment time, patient comfort and improving the management of outpatient. Radical hysterectomy and pelvic lymphadenectomy with or without bilateral total pelvic radiation therapy plus chemotherapy. Radical hysterectomy and bilateral pelvic lymphadenectomy can be considered for women with stages ib the iia disease.
An Italian group randomly assigned 343 women with ib stage and cervical cancer iia to surgery or radiotherapy. adjuvant radiotherapy was administered to patients at high risk pathological features in the sample of the uterus or positive lymph nodes. The main outcome was bone to 5 years, with secondary measures of rate of recurrence and complications. Complications were higher in patients who received adjuvant radiation after surgery. In general, radical hysterectomy should be avoided in patients who are likely to require adjuvant therapy. Based on the recidivism rate in previous clinical trials, two recurrence risk classes were defined. Patients with a combination of large tumor size, lymph vascular space invasion, and deep stromal invasion in the hysterectomy specimen is considered to have intermediate risk disease.
Patients in both arms received 49 Gy to the pelvis. There were evaluated 268 patients with a primary endpoint of the bone. The results of the study were reported at the beginning due to positive results in other trials of concurrent cisplatin and radiation therapy. As expected, the grade 4 toxicity was more common in the chemotherapy group and radiotherapy, with a predominant hematological toxicity.
Radical surgery was performed for small lesions, but the high incidence of pathological factors leading to postoperative radiation with or without chemotherapy make primary concomitant chemotherapy and radiation a more common approach in patients with larger tumors. Cancellation of the order of 50 Gy administered for 5 weeks plus chemotherapy with cisplatin with or without 5-fu should be considered in patients at high risk of recurrence. Patients with the alleged disease at an early stage who desire future fertility may be candidates for radical Trachelectomy. Although there have been a bone of improving the experimental arm, the results do not reflect current practice. Bone the primary endpoint, the trial may define whether there is a role for neoadjuvant chemotherapy in this patient population. pelvic radiotherapy external beam combined with two or more applications intracavitary brachytherapy is an appropriate treatment for patients with stage IA2 and IB1 lesions. For patients with stage IB2 and larger lesions, radiosensitization chemotherapy is indicated.
The role of radiation chemotherapy in patients with stage IA2 and IB1 lesions has not been tested. However, it may be beneficial in some cases. IMRT is a radiation therapy technique that allows a conformal dose of anatomical target while sparing surrounding tissue.

Effect of tumor size on cervical cancer prognosis treated by irradiation alone. randomized study of radical surgery versus radiotherapy for iia ib-stage cervical cancer. The recommendations of the American Brachytherapy Society for brachytherapy low dose rate for carcinoma of the cervix. The recommendations of the American Brachytherapy Society for brachytherapy high dose rate for cervical cancer.
