Ga-67 scan in patients with intrathoracic esophageal carcinoma planned for surgery.

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 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.

Postoperative thallium-201 myocardial images. Evidence of regression of right ventricular hypertrophy in man.

Thallium-201 myocardial scintigraphic studies were performed on 24 patients with chronic right ventricular overload before and after surgical correction of haemodynamic overload. The ages of the patients ranged from 20 to 65 years (mean 39 years) at operation. The degree of right ventricular visualisation remained essentially unchanged in an early postoperative study (four to 60 days), though a decrease in right ventricular cavity size was noted in patients with right ventricular volume overload. On later follow-up (18 to 36 months), thallium uptake in the right ventricle was definitely less than before operation in all 13 patients studied at this time. Because thallium-201 radioactivity reflects myocardial blood flow and mass, our study indicates that right ventricular hypertrophy is largely reversible. Thus, thallium-201 myocardial scintigraphy can be used to assess non-invasively regression of right ventricular hypertrophy in patients with right ventricular overload.

Survival time and "cure" in papillary and follicular thyroid carcinoma with distant metastases: statistics following University of Michigan therapy.

Between 1947 and 1980, 103 patients with well-differentiated thyroid carcinoma with metastases outside the neck were treated with sodium iodide (I-131) after surgical treatment. Forty-one patients had distant metastases first detected an average of 7.44 yr after the initial operation establishing the diagnosis of thyroid carcinoma. Follicular and papillary carcinomas gave the same survival time in patients, matched for age and sex, who had metastases outside the neck. Those considered to be free of their metastatic disease after I-131 therapy survived three times as long as those with persistent disease. Patients freed of their metastases had a higher conformity rate with half of our ten procedures of "ideal" treatment, compared with patients not freed of their metastases.
