title: [Comparative study of the patients with renal cell carcinoma before and after 1980].
abstract: Patients with renal cell carcinoma treated at Jikei University and affiliated institutions were studied with regard to temporal differences. Our study population was divided into two groups: an earlier group comprising 169 patients treated between January 1957 and December 1979, and a later group comprising 165 cases treated between January 1980 and December 1984. The mean age in the earlier group was 56.2 years, while that in the later group was 60.4 years. Therefore, the patients in the earlier group were generally younger than those in the later group. Patients in the earlier group were more likely to present with urinary symptoms at the time of diagnosis. On the other hand, patients in the later group were more likely to present with extra-urinary symptoms or to be asymptomatic. The time period between the onset of symptoms and initial consultation with physician was longer (within one month) in the earlier group. Most patients in the later group underwent nephrectomy using the transperitoneal or thoracoabdominal approach. Few patients in the later group were treated with radiotherapy. As adjuvant chemotherapy, MFC (MMC, 5-FU and Ara-C) or MACV (methotrexate, actinomycin D, cyclophosphamide and vincristine) regimen were most commonly employed in the earlier group. FAV (5-FU, adriamycin and vinblastine) regimen or interferon therapy which was classified as biological response modifiers (BRM) were more commonly employed in the later group. More cases were diagnosed as stage II in the earlier group, and more cases were diagnosed as stage IV in the later group. No significant differences were observed between the earlier and later groups, with regard to 5- and 10-year survival rates.(ABSTRACT TRUNCATED AT 250 WORDS)
