The Value Of Real-time Ultrasound-guidance In Intracavity And Interstitial Implantation Brachytherapy For Advanced Cervical Cancer

Object：Explore the real-time ultrasound-guided brachytherapyimplantation of value between advanced cervical cancer.Methods：Select our hospital from April2013to June2014radiotherapydepartment treated46cases of cervical cancer patients, aged24-75years old, with an average age of50.23years old，All patients hadclear stages and pathological diagnosis of cervical cancer results，According to 《2012NCCN Clinical Practice Guidelines for CervicalCancer》standard, In2cases in which ⅠB2, ⅡA2of5cases, ⅡB of20cases, ⅢA of5cases, ⅢB11cases, ⅣA3cases。28casesin which ultrasound-guided endovascular brachytherapy treatmentplus organizations，Total number of needle341implantation, uterinetube208, marked to guide group，Another18cases between the cavitywithout ultrasound irradiation plus tissue implantation boot linetreatment, a total number of needle132transplanting, uterine tube107, a non-standard guide group。All patients were administeredthe source device using Utrecht，According to the surgeon and otherradiological image data in real-time ultrasound-guided into the selected position of the pinhole, Almost fixed needle angle is notadjustable，The maximum depth of the same every single needleimplantation, are5cm。Developed a scoring system， based on thedepth of the needle on two different implantation conditions werescored,also on the uterine cavity tube placement data comparisonbetween the two groups。Results：The basic situation of the data comparing the two groups ofpatients p>0.05, not statistically significant；Guided group andnon-guided group, respectively, with a median depth of3.0cm,2.0cm,unguided group was significantly lower than guided group； Themedian distance between the guide group and non-group guide betweenthe tip and the CTV-HR is respectively0.2cm,-1.0cm, guide groupinstead of the guide in the preferred range, group is clearlyinsufficient level; Guided and non-guided group group interpolatedmedian scores were needle score is4.95points,4.0cm; guidance fromthe leading group and non-group between the depth of the needle tipand the CTV-HR, the interpolation needle score results data、theuterine tubes contrast score resultscomparison, pare less than0.01, the difference was statistically significant; The operatingtime, the difference was statistically significant; short-termcomplications, guided group was significantly less than the non-guided group. Conclusion：Real-time ultrasound-guided technique interpolationbetween cervical cancer brachytherapy in the extent ofdamage to a minimum depth of the needle to optimize theimplantation, streamline operations and reducecomplications.
