Chemoprevention of development of colonic adenomatosis and carcinomatosis with intrarectal dose of 5‐FU on animal model

This study concerns the treatment by chemotherapy of carcinogenically‐induced cancers in the colons of rats. These cancers mimic adenomatosis and carcinomatosis in humans. We believed that they could be prevented or regulated from growing into grossly visible tumors by the intrarectal administration of 5‐fluorouracil if the treatment was started on nascent cancers. The incidence of colon carcinoma and the number of tumors per rat were significantly lower in rats treated by this method than in the control rats. Furthermore, some of the small tumors visible by endoscopy disappeared with treatment. This beneficial effect appeared to be due to the direct delivery of an active form of anticancer drug administered in high concentration to the target lesions in the colon mucosa, and carried fewer side effects when compared to other parenteral administrations.

A Case of Double Pylorus

Kenichi Kohno; Toshiharu Yamaguchi; Toshio Takahashi; Hisayuki Masuda

Doubling of the pyloric channel is one of the rare anomalies of the intestinal tract. There have been 23 cases of double pylorus that we have been able to find in the literature.1–6,9–12,14–17 As the etiologic aspects of double pylorus the majorities of the cases were thought to be acquired lesions from ulcer disease except three cases. We present a case of double pylorus which seems to be acquired lesion, with a review of the literature.

切除を行った65歳以上の胃癌症例を, 65~74歳のA群 (244例), 75~79歳のB群 (74例), 80歳以上のC群 (40例) に分けて治療成績を検討した.手術方針としてA群では進行度に応じて拡大手術も行ったが, C群では, なるべく合併切除を避け, リンパ節郭清はD1郭清を原則とした.その結果, 手術時間はA群234分, B群193分, C群129分と, 高齢者ほど有意に短く, 術中出血量もA群672g, B群517g, C群327gと, C群で有意に少なかった.術死はA群2.5%, B群2.7%, C群5.0%と差を認めなかった.術後合併症は, 肺合併症がC群にやや多いほかは, 3群間に差を認めなかった.5年累積生存率はA群58.7%, B群47.9%, C群31.1%とC群が有意に低かった.術死・他病死を除いても, 生存率は年齢が進むほど低い傾向を認めた.80歳以上の胃癌に対する縮小手術の方針により直接成績では, 79歳以下と差のない成績が得られたが, 遠隔成績において癌再発が多くなる傾向を認めた.

1983年から1988年までの間に教室で切除を行った胃癌422例を周手術期 (術前・術中・術後) に輸血を行わなかった非輪血群 (226例), 1,000ml未満の輸血を行った1,000ml未満群 (105例), および1,000ml以上の輸血を行った1,000ml以上群 (91例) の3群に分け, 周手術期の輸血が胃癌の生存率におよぼす影響について検討した.5年累積生存率は80.5%, 46.4%, 32.6%の順となり, 各群の間に有意差を認め, 輸血量の多い症例ほど生存率は不良であった.しかし, 輸血量が多かった症例では, 高齢者, 病期の進んだ症例, 肉眼型が浸潤型, 深達度の深い症例, リンパ節転移陽性例および胃全摘を行った症例がより多かったので, 組織学的病期別に生存率を比較した.その結果, stage IIおよびIVでは, 非輸血群の生存率が輸血1,000ml未満群および輸血1,000ml以上群と比べて有意に良好であったことからこれらのstageでは周手術期の輸血が予後を不良にしている可能性があるものと考えられた.

制癌剤を懸濁した油性造影剤リピオドール (Lipiodol) の動注療法に多剤併用療法を応用し効果増強を試みた. すなわち, 5-フルオロウラシルまたはカルモフール, アドリアマイシンおよびマイトマイシンCを同時にリピオドールに懸濁し (350~1,000mg, 20~40mg, 10~30mg/5~20ml), 肝悪性腫瘍に対して動注したところ, 転移性肝癌に対しては10例中7例 (70.0%) に腫瘍縮小が, 8例中7例 (87.5%) に腫瘍マーカーの減少が認められた. 本療法をさらに発展させ, 種々の腫瘍に対してその腫瘍の性質に合わせて制癌剤を選べば, 今後一層の効果が期待でき, 将来有望と思われる.
