Assessing disease extent in women with bulky or clinically evident metastatic cervical cancer: yield of pretreatment studies.

OBJECTIVE: The objective of this study was to determine the impact of pretreatment tests on staging and management for women with bulky or clinically evident metastatic cervical cancer. METHODS: Demographics and findings of clinic pelvic examination (PE), examination under anesthesia (EUA), chest x ray (CXR), abdominopelvic computed tomography (CT), and intravenous urography (IVU) were reviewed for women with primary, untreated cervical cancers either > or =4 cm or with extracervical disease apparent on PE or CXR evaluated between July 1, 1994, and March 31, 1999. Stage was assigned according to standards of the International Federation of Gynecology and Obstetrics. RESULTS: In 133 women studied, tumor diameter averaged 4. 9 cm on PE and 5.7 cm at EUA (P = 0.0005). Of 92 women undergoing both PE and EUA, 30 (33%) had size discrepancies of more than 1 cm. Compared with EUA, PE had sensitivity, specificity, and positive and negative predictive values, respectively, of 65, 89, 79, and 81% for vaginal disease, 74, 91, 95, and 63% for parametrial disease, and 57, 90, 60, and 89% for sidewall fixation. CXR was abnormal in 5 (4%). IVU showed ureteral dilation in 20 (22%) of 90 women, while CT showed dilation in 34 (28%) of 123 women. CT also showed pelvic lymphadenopathy in 22 (18%) women and paraaortic lymphadenopathy in 12 (10%). Bladder biopsies showed malignancy in 8 (8%), including one transitional cell carcinoma of the bladder. Proctoscopy failed to reveal metastatic cervical cancer. CONCLUSIONS: CXR and EUA with cystoscopy are important to the accurate staging and treatment of bulky or clinically metastatic cervical cancers, while proctoscopy is rarely useful. CT predicts ureteral obstruction well, and its greater information yield may justify its higher cost compared with IVU.

Computed tomography screens stable patients at risk for penetrating cardiac injury.

OBJECTIVE: To determine the accuracy of CT of the chest in diagnosing the presence of cardiac injury in stable patients with penetrating chest injuries. METHODS: A retrospective chart review of a convenience sample of stable patients with penetrating thoracic wounds evaluated for hemopericardium using chest CT at an urban level I trauma center. RESULTS: 60 stable patients with penetrating wounds in proximity to the heart underwent CT. Three patients had radiographic evidence of pericardial fluid, and 1 had an equivocal study. These 4 patients underwent subxiphoid pericardial window exploration: 2 had only clear fluid present, the other 2 had hemopericardium. The latter patients had a total of 3 cardiac and 1 diaphragmatic injuries, which were repaired at subsequent sternotomy. None of the 56 patients who had negative CTs had further clinical evidence of cardiac injury. The sensitivity, specificity, and accuracy of CT in this setting for hemopericardium are 100% (95% CI 18-100%), 96.6% (95% CI 88-100%), and 96.7% (95% CI 89-100%), respectively. CONCLUSION: Chest CT may be a useful test for diagnosing the presence of hemopericardium in the setting of penetrating thoracic injury. With the caveat that the patient must be removed from a closely monitored environment, the authors the use of CT in stable patients with penetrating chest wounds whenever echocardiography is unavailable.
