title: [Lymphoscintigraphy with (123)I-marked epidermal growth factor in cervix cancer].
abstract: Several malignant neoplasms express high levels of epidermal growth factor receptors. The aim of this study was to assess whether 123I-labeled epidermal growth factor can concentrate in lymph node metastases of squamous cell carcinomas of the cervix. 14 patients with advanced cervical cancer were selected because of their high probability of lymph node metastases. Planar scintigrams were recorded from the lower and upper abdomen following subcutaneous injection of 123I-labeled epidermal growth factor into the web space of each foot. Scintigraphic images were interpreted without knowledge of computerized tomography scan (n = 13) and ultrasound (n = 9) results from the pelvic lymph nodes. In 2 patients, histological verification was performed by diagnostic biopsy of pelvic lymph nodes. Nodal involvement was confirmed by computerized tomography for 4 of the 11 positive scans and by ultrasound for 2. In 11 out of 14 patients an increased uptake of 123I-labeled epidermal growth factor could also be seen in the primary tumour. Our findings suggest that targeting of cervical cancer lymph node metastases can be achieved by in vivo binding of 123I-labeled epidermal growth factor with receptors on tumour cell surfaces.
