Abstract
Aim:
To compare the findings of CT scan pelvis and cystoscopy findings of bladder involvement in carcinoma cervix in VIEW of revised FIGO staging and to demonstrate the accuracy of CT scan for pretreatment diagnosis of bladder involvement.
Methods:
A prospective and comparative study was conducted in the department of Obstetrics and Gynaecology, Rajindra hospital Patiala on a number of 100 patients of carcinoma cervix who underwent both cystoscopy and CT scan pelvis to ascertain bladder involvement. Cystoscopy guided biopsy proven cases of bladder involvement were taken as true cases of bladder involvement in the study and the results of both modalities were analysed and compared.
Results:
Out of 100 patients of carcinoma cervix, 28 patients showed bladder involvement on CT scan pelvis and 6 patients were proven as positive cases on cystoscopic guided bladder biopsy. The true positives in the study were 6 cases. True negatives were 94 cases. 22 patients were false positive on CT scan findings and there were no false negative patients for bladder involvement on CT scan pelvis findings in the study. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT scan pelvis for bladder involvement were 100%, 76.60%, 21.43%, 100% and 78% respectively. CT scan pelvis was able to detect all cases of bladder involvement which came positive cystoscopy guided biopsy as well.
Conclusions:
With the revised FIGO staging which has given optional status to both CT scan and cystoscopy for bladder involvement in patients of carcinoma cervix, CT scan can be used as the preliminary modality for detective bladder involvement in patients of carcinoma cervix. The high sensitivity and negative predictive value of CT scan helps choose which patients should undergo cystoscopy and helps in better and more efficient pre-treatment evaluation of patients with carcinoma cervix for bladder involvement.
