Clinicopathological study for gastric cancer with liver metastasis.

Clinicopathological characteristics, stromal volume (Vvf), nuclear DNA content and cell protein were retrospectively analyzed in order to scrutinize the risk factors of hepatic metastasis from carcinoma of the stomach. We conducted a clinicopathological study of 327 patients with gastric cancer, including 34 patients with liver metastasis (synchronous, 22; metachronous, 12) and 294 patients without liver metastasis. Univariate analysis revealed significant inter-group differences in tumor size (p<0.001), depth of invasion (p<0.001), lymph node metastasis (p<0.001), vascular involvement (p<0.001), lymphatic involvement (p<0.001), peritoneal dissemination (p<0.05), Vvf (p<0.01) and DNA content (p<0.01). Vvf and DNA content were estimated in the liver metastasis group (n=20) and in the group of patients with stage III-IVa carcinoma but without liver metastasis (n=11). In multivariate analysis, only Vvf and DNA content showed significant correlations with liver metastasis (p<0.01). A comparison of Vvf and expression of the amount of interstitial connective tissue showed that there as a significant correlation between them. Our results indicate that gastric cancer with low Vvf and high DNA content carries a high risk of hepatic metastasis. Therefore, mean DNA content and Vvf are useful indices for predicting liver metastasis from gastric carcinoma.

Prognostic Factors in the Patients with Carcinoma of the Middle and Lower Bile Duct. Analysis of Nuclear DNA Content, MIB-1 Score and Expression of the p53 Protein.

Yasuo Yamada; Hidemi Yamauchi; Kenji Kakizaki

中下部胆管癌切除例28例を対象として, モノクローナル抗体MIB-1/Ki-67により表現される腫瘍増殖活性, p53蛋白発現ならびに核DNA量の予後規定因子としての意義を検討し, 病理組織学的因子との比較を行った. 病理組織学的因子と予後との関係では, stage I~IIIとIVの間で, また下部胆管癌においてpanc (-) 群と (+) 群との間で生存率に有意差がみられた (p<0.05). 平均核DNA量が5c以上の群は5c以下の群に比べて有意に予後不良であった (p<0.05). MIB-1 score (染色陽性率) 10%以下の群は10%以上の群に比べ有意に予後良好であった (p<0.01). p53蛋白発現の有無による予後の差はみられなかった. 病理組織学的因子と平均核DNA量, MIB-1 scoreとの間に有意な相関はみられなかった. 以上の結果より, 平均核DNA量, MIB-1, scoreは中下部胆管癌の予後規定因子として有用と思われた.

A Case Report of Amputation Neuroma of the Biliary Tract Following Gastrectomy.

Kenji Kakizaki; Yasunori Kikuchi; Hidemi Yamauchi

胆道系に発生する断端神経腫の多くは胆嚢摘出術後に認められるものである. 今回われわれは胃切除術のみの既往があり, 消長する黄疸を主訴とし, 切除標本の病理学的検索で総胆管の断端神経腫と診断された1例を経験した. 手術1年半前の経皮的胆管造影では壁平滑な全周性の胆管狭窄を認めたが症状軽快のためいったん退院, 黄疸の悪化のため再入院した際には総胆管の完全閉塞を示した. 術前胆汁細胞診, 術中迅速診で悪性所見を認めず, 胆管切除術および肝管空腸吻合術を施行した. 術後の病理学的検索により断端神経腫の診断が得られた. 術後経過は良好で黄疸の再発などは認められていない.
