Epithelial mucins of the normal terminal ileum, caecum, colon, and rectum of man are unique in that they alone exhibit staining following the periodate-borohydride/KOH/PAS technique. Application of this technique enables one to differentiate those mucin-producting metastases arising from adenocarcinoma of the lower gastrointestinal tract from those arising elsewhere, and may occasionally be useful in determining the site of the primary tumour when it is in doubt. Furthermore, it was found to be especially useful in distinguishing between primary adenocarcinoma of the lung and metastases in the lung from adenocarcinoma of the lower gastrointestinal tract.
人类正常回肠末端、盲肠、结肠和直肠的上皮粘蛋白具有独特之处,即只有它们在用高碘酸盐-硼氢化物/KOH/过碘酸希夫氏反应(PAS)技术处理后会出现染色。应用该技术能够区分下消化道腺癌产生的粘蛋白生成性转移灶与其他部位产生的转移灶,并且在原发性肿瘤部位存疑时,偶尔有助于确定原发性肿瘤的位置。此外,还发现该技术在区分原发性肺腺癌与下消化道腺癌的肺转移方面特别有用。
