Local excision of malignant melanoma promotes both disruption and regeneration of regional lymphatics. These disturbances in local lymphatic drainage favor escape of residual melanoma cells either locally or in transit from more distal sites. Accordingly, a wide tridimensional resection to eradicate all local tumor and circumvent interstitial entrapment and migration of melanoma cells is still advocated. Changes in lymph vessels after excision also demand caution when distal endolymphatic isotopes are administered. Lymph leakage and trapping with overconcentration of the isotope may result in excess local irradiation and skin breakdown.
A prospective study of computerized tomography (CT) of the liver using a liver contrast agent compared to conventional CT was undertaken. CT scanning without contrast agents (NC-CT), CT with water-soluble contrast (WSC-CT), and CT with ethiodized oil emulsion (EOE-CT) were performed on patients with possible or probable hepatic metastases. The findings on these three examinations were compared to the objective findings at surgery in 53 patients. Accuracy of these examinations was 80.7% for NC-CT, 77.1% for WSC-CT, and 84.9% for EOE-CT. The true-positive percentage for 129 hepatic lesions was 40.6% for the NC-CT, 33.6% for WSC-CT, and 76.7% for the EOE-CT. Eighty-three percent (44/53) of 1- to 2-cm liver lesions were detected by EOE-CT, whereas only 26.4% (14/53) lesions of this size were detected by the NC-CT and 20.4% (10/49) shown by WSC-CT. The likelihood that a lesion seen by CT scan was malignant was 84.6% for NC-CT, 89.4% for WSC-CT, and 81.8% for EOE-CT. The EOE contrast agent improves the sensitivity of liver CT for detecting hepatic metastases. The improvement occurs with lesions 1 cm and greater in diameter, but is particularly striking for lesions of 1 to 2 cm in diameter.
