Abstract:
A series of 510 patients with carcinoma of the uterine cervix given the curative radiation therapy from March 1979 through December 1986 was evaluated to determine the value of intravenous pyelography(IVP), cystoscopy, sigmoidoscopy, and abdomino-pelvic CT as staging work-up prior to treatment. On IVP and cystoscopy, 10.7%(49/456) and 5/3%(24/452) showed abnormality, respectively, but only 0.7% (3/413) did on signoidoscopy. As a result of these work-ups prerequisite to FIGO staging, twenty six (5.1%) out of 510 patients were upstaged from the stage determned by the findings of physical examination alone. The proportions of upataging in each stage were as follows none in stage IB(35), IIA (89) and IIIA(8), 7.9%(20/252) in stage IIB(14 patients to FIGO Stage IIIB, 6 patients to FIGO stage IVA), and 4.8% (6/126) in stage IIIB (all to FIGO stage IVA). Positive findings of staging work-ups were found only in patients with advanced stages of stage IIB or over determined by physical examination alone but not in those with earlier stages. CT was performed in 337 patients. CT detected pelvic lymph node (LN) enlargement in 25.2% (85/337) and paraaortic LN enlargement in 7.4% (25/337). Pelvic LN positivity was well correlated with increasing stage but paraaortic LN positivity was not. In the evaluation of parametrial involvement, CT findings were in accordance with those of physical examination only in 65.6%(442/674). When compared with endoscopic studeies, CT had much lower positive predicitive value than negative predicitive value in the evaluation of adjacent organ invasion. The staging work-ups should be individualized by the disease extent of each patient, and then the efficiency of work-ups may be increased without compromising the appropriate FIGO staging and treatment.
