Cervical lymph node metastasis was evaluated sonographically in 58 esophageal cancer patients. The short to long axis ratio (S/L) is a useful way to detect lymph node metastasis as opposed to the long axis alone. In other words, the lymph node exceeding 10 mm in long axis and with S/L over 0.5 showed a much higher incidence of metastasis than S/L under 0.5 in the analysis of the 126 detected lymph nodes. The cancer content was calculated with a microcomputer in each of the total 77 metastatic… CONTINUE READING
