The Role of Endorectal Ultrasonography in the Follow-up Evaluation of the Uterine Cervical Carcinomas in Intra-arterial Cisplatin Chemotherapy
Abstract
- PURPOSE
lntra-arterial cisplatin infusion chemotherapy delivers higher
concentration of this therapeutic agent to the limited area of cervical carcinoma. We
evaluated the role of endorectal ultrasonography (ERUS) in the analysis of the
tumor response to this chemotherapy.
MATERIALS AND METHODS
ERUS was done in 20 patients of cervical carcinomas
limited to the pelvis by rotating the 5 UHz linear arraytransducer along the
reference sagittal plane in the middle of uterine cervix and vagina. We examined and
compared the change of tumor size and morphology on ER US, before, during and
after intra-arterial cisplatin (50 mg/m2) chemotherapy through internal lilac
artery near uterine arterial branching. Colposcopy and radical hysterectomy with
pelvic lymphadenectomy were performed in all patients, and ERUS findingswere
compared with those findings.
RESULTS
ERUS correlated well with surgery in the estimation of preoperative
tumor size and morphology. Tumor reduction rate on ERUS (100-the largest area
of the preoperative tumor/the largest area of the initial tumor) was as follows:
more than 75% decrease of the original size in 3 patients, 75% -50% in 6 patients,
50%-25% in 8 patients, and less than 25% in 3 patients. Hyperechoic reflecting
areas were noted in 4 patients, which corresponded to gaseous necrosis on
postoperative pathology.
CONCLUSION
ERUS is helpful to evaluate the morphologic change of cervical
carcinoma limited tothe pelvis in intra-arterial cisplatin chemotherapy.
