高齢者膀胱癌の治療成績

Abstract

1) 1975年から1982年までに千葉大学泌尿器科で治療を受けた膀胱腫瘍患者は205例であり, 70歳以上の高齢者はこのうち70例であった.2)若年者群に比べ女性の患者の比率が高くなる傾向を示し, 異型度の強い腫瘍が多くなる傾向を示した.3)表在性腫瘍の予後は癌死が少なく他因死が多いので, 治療はTURが適当である.4)浸潤性腫瘍の予後は若年者群と同様, 大半が癌死であった.5) High grade, Low stageの腫瘍と高齢者に比較的多く, 膀胱保存的治療と厳重な経過観察により, 良好な治療成績をおさめた

Seventy of the 205 patients treated for bladder cancer in the past 8 years were over 70 years old (older group). The male to female ratio was 2.2 in older group, and that for the younger group was 4.1. The incidence of high grade cancer was larger in the older group than in the younger group. The 5-year survival rate was 42% for the older group and 66% for the younger group. The older patients with superficial cancer died mostly because of other causes and those with invasive cancer died of cancer. Eight cases of high grade, low stage cancer were treated by TUR or radiation, and they were well-controlled.
