The authors evaluated Ga‐67 scan in 68 patients with intrathoracic esophageal carcinoma initially planned for surgery. Of these, 59 patients were staged pathologically or surgically; their Ga‐67 scan results were then compared with the results of pathologic or surgical investigations. Positive Ga‐67 scan results correctly predicted the presence of extraesophageal spread and lymph node metastases. Of 38 clinical Stage II patients, 15 (39%) could be Stage III by the results of Ga‐67 scan. However, two of four clinical Stage I patients (50%) and 35 of 38 clinical Stage II patients (92%) were eventually pathologic or surgical Stage III. This high conversion rate and the high incidence of Stage III in esophageal carcinoma patients may not justify routine use of Ga‐67 scan only for staging. Ga‐67 scan, however, was useful for planning radiotherapy, because missing extraesophageal extension or gross metastases from the radiation fields were detected in six patients of 51 so treated. Ga‐67 scan has its value in some patients with intrathoracic esophageal carcinoma.
