title: [Role fo ultrasound in the study of latero-cervical metastases].
abstract: In patients undergoing radiotherapy (RT) for malignant neoplasies of the head and neck the availability of a diagnostic method permitting frequent, easy checkups of the latero-cervical lymph nodes would be extremely useful. This is especially so because clinical examination is often hindered by the post-actinic fibrosis of the tissues. Among the methods presently available for this purpose (CAT, NMR, lymphoscintigraphy, xerography, ultrasound) echotomography appears to be the most indicated as it is least invasive, can easily be repeated and is not difficult to perform. The refining of ultrasound techniques would, as reported in the literature, make it possible today to evaluate the effects of RT on latero-cervical metastases both during and some time after treatment. The authors, therefore evaluated the advantages and limitations of the method examining 33 patients undergoing RT for latero-cervical metastases due to head and neck carcinoma. Each patient underwent ultrasound examination prior to, during and at the end of the RT treatment cycle. Once treatment had been terminated 18 underwent latero-cervical neck dissection. Upon termination of the radiation treatment three distinct types of ultrasound behaviour were identified: complete response; partial response; minimal or negligible response. For those patients undergoing surgery this response was compared to lymph node chain histology while, for the others, it was compared to the ultrasound findings of subsequent examinations. The results obtained appear to indicate that a systematic scheduling of ultrasound checkups offers a reliable evaluation of how metastatic adenopathies respond to RT. At times such response can only be completed several months after treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
