TL;DR: FDG PET/CT has higher sensitivity than MDCT in the identification of sites of recurrent and metastatic disease in patients with colorectal cancer and an elevated CEA level and the two techniques appear to have similar specificity.
Abstract: OBJECTIVE. The purpose of this study was to compare FDG PET/CT and contrast-enhanced 64-MDCT of the chest, abdomen, and pelvis in the detection of tumor recurrence in patients with colorectal cancer and an elevated level of carcinoembryonic antigen (CEA).MATERIALS AND METHODS. A retrospective analysis included 50 patients (31 men, 19 women; mean age, 61 years; range, 28–89 years) with 55 clinical events of elevated or increasing CEA level who underwent FDG PET/CT and MDCT for suspected tumor recurrence.RESULTS. Recurrent or metastatic disease was found in 36 of 55 events (65.5%) of elevated CEA. Fifty-four of 61 tumor sites suspected as tumor recurrence with any imaging technique were found to be local recurrence or metastatic colorectal cancer at final analysis. The other seven sites were one separate malignant tumor (small lymphocytic lymphoma) and six benign lesions. Diagnosis was based on histopathologic findings (n = 27) or clinical and imaging findings (n = 35) during a median follow-up period of 12...

TL;DR: The accurate localization of colorectal carcinoma recurrences by means of 111In ZCE-025 monoclonal antibody demonstrates the usefulness of this diagnostic agent in the setting of elevated carcinoembryonic antigen level and negative results of clinical and radiologic workup.
Abstract: • We investigated the utility of scanning with indium 111 labeled to monoclonal antibody in 13 patients after curative resection of colorectal cancer who had elevated carcinoembryonic antigen levels and negative results of clinical workup. Each patient received 1 mg of anti–carcinoembryonic antigen monoclonal antibody type ZCE 025 labeled with 5.5 mCi of111In, plus 9 to 39 mg of the same antibody unlabeled. Patients underwent scanning 3 to 7 days after infusion by planar and emission computed tomography. ZCE-025 monoclonal antibody imaging detected tumor recurrence or metastasis in 11 of 13 patients. In one patient the monoclonal antibody scan gave a true-negative result, and in one patient the monoclonal antibody scan failed to disclose a metachronous cecal primary. Tumor sites identified were the pelvis (2 patients), abdominal wall (2), retroperitoneum (1), lymph nodes (3), liver (2), bone (2), and lung (1). The accurate localization of colorectal carcinoma recurrences by means of111In ZCE-025 monoclonal antibody demonstrates the usefulness of this diagnostic agent in the setting of elevated carcinoembryonic antigen level and negative results of clinical and radiologic workup.

TL;DR: Many asymptomatic patients suspected to have recurrent colorectal cancer based on an elevated carcinoembryonic antigen level will be spared unnecessary operation if strict attention is paid to their preoperative evaluation.
Abstract: Summary Many asymptomatic patients suspected to have recurrent colorectal cancer based on an elevated carcinoembryonic antigen level will be spared unnecessary operation if strict attention is paid to their preoperative evaluation. Liver and renal function should be assessed. Unresectable extraabdominal and intraabdominal recurrence or metastases should be excluded. Patients being evaluated for recurrence after curative resection of a rectosigmoid cancer should undergo a bone scan. Having satisfactorily ensured normal results for these investigations, the surgeon should then proceed to search for an intraabdominal source of tumor recurrence.

TL;DR: The aim of this study was to evaluate the false positive rate for pleural fluid carcinoembryonic antigen (CEA) level in non‐malignant pleural effusions and to determine whether the falsely elevated CEA level has any relation to other biochemical parameters of pleural Effusions.
Abstract: Objective: The aim of this study was to evaluate the false positive rate for pleural fluid carcinoembryonic antigen (CEA) level in non-malignant pleural effusions and to determine whether the falsely elevated CEA level has any relation to other biochemical parameters of pleural effusions. Methodology: We performed a retrospective analysis of 654 consecutive patients with a pleural effusion admitted to the pulmonary department of a tertiary referral teaching hospital from March 1997 to March 1999. The aetiology of the pleural effusions were classified as tuberculosis (n = 262), malignancy (n = 204), pneumonia (n = 145), exudates of other origin (n = 28) and transudate (n = 1). Results: A false positive result for pleural fluid CEA level (> 5 ng/mL) was registered in 13.8% of non-malignant pleural effusion cases: empyema (38.6%), parapneumonic effusion (14.7%), exudates of other origin (14.3%), tuberculosis (7.3%) and transudate (6.7%). In analysis of the subgroup with false positive results for pleural fluid CEA level, the CEA level of non-malignant pleural effusion showed a significant relationship to the severity of pleural inflammation in terms of the following variables: LDH (rs = 0.4201, P= 0.001), adenosine deaminase (ADA) (rs = 0.4440, P= 0.0004), white blood cell count (rs = 0.4266, P= 0.0004), polymorphonuclear cell percentage (rs = 0.5080, P= 0.0001), and polymorphonuclear cell count (rs = 0.5095, P= 0.0002). In the parapneumonic effusion and empyema groups, the changes in pleural fluid CEA level exhibited a positive association with the changes in the pleural fluid ADA level (rs = 0.8143, P= 0.0002). Conclusions: The results from our series indicated that false positive results for pleural fluid CEA level were most commonly observed in patients with empyema and parapneumonic effusion and the CEA level showed a significant correlation to the indices of pleural inflammation. The serial measurement of pleural fluid CEA level may be useful as a means of monitoring resolution of pleural inflammation and excluding the possibility of a malignant pleural effusion.

TL;DR: Carcinoembryonic antigen levels were simultaneously determined in the aqueous humor and in the plasma of the 3 patients with primary malignant malignant melanoma undergoing enucleation.
Abstract: Carcinoembryonic antigen levels were simultaneously determined in the aqueous humor and in the plasma of the 3 patients with primary choroidal malignant melanoma undergoing enucleation. An elevated carcinoembryonic antigen level was detected in the aqueous humor of 1 patient with no increase in plasma CEA level. In the other 2 patients no such elevation was found. A local increase of CEA levels produced by the tumor is likely to occur. Further studies are required of CEA levels of patients with primary malignant choroidal melanoma as an aid in diagnosis and treatment of this condition.
