Of the 173, 265 people who had general health checkups at Oriental Clinic for the 11year period from 1987 to 1997, 33 cases of renal cell carcinoma have been discovered. In all of the cases, renal abnormalities were first indicated in abdominal ultrasound tests and patients were transferred to other medical institutions, where they were submitted to histological diagnoses and operations. The author studied the patients subjective symptoms, whether or not abnormal data was found in their clinical tests, relations among the size of tumors, progressive stages, pathological grades (atypia) and echoes inside the tumors (echo brightness and patterns), and also patients prognoses. As a result, it was found that in most of the cases none of the three major signs characteristic of renal cell carcinoma (gross hematuria, pain in the kidney or tactile tumors) was detected. In main abnormal findings in clinical tests, abnormal erythrocyte sedimentation rates were indicated in two cases and CRP positive was found in one case. There was not any case of anemia, polycythemia or hypercalcemia. Major axes of the tumors ranged from 15mm to 107mm. Regarding the progressive stages of tumors, which were mainly diagnosed at the other medical institutions, six cases of pT1, 20 cases of pT2, two cases of pT3, one case of pT4 and four cases of unknown stages were found with the TMN staging. According to the Robson staging, on the other hand, the patients were classified into 26 cases of the I stage, four of the II stage, one of the III, another one of the IV and one case of unknown stage. In the relation among the size of tumors, progressive stages, echo brightness and echo patterns, cases with smaller and less progressed tumors tended to show more hyperechoic and homogenous tumors. Mean tumor size was 31.0 ±13.4mm and 50.9±15.1mm in diameter in the eight cases with G1 atypia and eight cases with G2, respectively. It showed that the tumor size tended to be smaller in G1 cases than G2.<BR>In all of the 33cases, the patients received radical nephrectomy, excluding one case in which partial nephrectomy was performed.<BR>Observation periods for patients' prognoses ranged from one year to 11 years (5.5 years in average) . One patient died, one was lost to followup and 31patients were alive.
