Abstract
Since the National Kyushu Cancer Center had established in 1972, nine hundred eighty seven patients who had abnormal sensation of the throat were examined in our clinic. These were about 19% of all 5314 out-patients in the Head and Neck Service of our hospital during six years. Initial sign of cancer of the cervical esophagus, hypopharynx, middle or lower esophagus, stomach and thyroid gland was occasionally abnormal sensation of the throat. Even if it is impossible to find malignancy in any region of such out-patient as them within two or three days, we have to continue various appropriate examination for cancer periodically. We should have no preconceived opinion to diagnose for a new out-patient. Probability that there are several patients with cancer among a great number of the out-patients who have abnormal sensation of the throat should be kept in mind at any time.
