The purpose of the study was to define and then to compare particularly the morphological profiles of the main morphological types of esophageal carcinoma (EC).
PATIENTS, MATERIALS AND METHODS: The studied group included 46 operated EC patients. Few parameters were clinical (gender and age). The rest of them described both gross and histological features of the entire group and of the two main histological types of carcinoma (lesion' site, lateral extension, lesion dimensions, gross aspect, and histological type, and tumor grade, and stage). Stratification scales of cases were defined according to each parameter in order to compare the data and a statistical apparatus [Student's t-test and χ² (chi-squared) test] was used.
The studied tumors were encountered mostly in mature adult and elderly men, usually in the lower segments of the esophagus. Many of them had between five and ten cm in the long diameter and produced stenosis. Most of them had infiltrating appearance combined often with protruding or∕and ulcerated aspects. Usually, the tumors were poorly differentiated and in stage III. The two main histological types of EC showed different morphological profiles. Data from the literature revealed sometimes wide ranges of variation for the studied morphological parameters. Our results were within these ranges of variation.
ECs proved to be aggressive and late diagnosed tumors in general, with distinct morphological and behavioral profiles for the two main histological types. Comparisons with literature data confirmed many of our observations regarding the clinical and morphological aspects of both ECs as a whole and its histological types.
本研究旨在定义食管鳞癌(EC)的主要形态学类型,并对其形态学特征进行比较。
患者、材料和方法:研究组包括 46 例接受手术的 EC 患者。少数参数为临床参数(性别和年龄)。其余参数描述了整个组和两种主要组织学类型的癌(病变部位、侧向扩展、病变尺寸、大体外观和组织学类型以及肿瘤分级和分期)的大体和组织学特征。根据每个参数定义了病例分层尺度,以比较数据,并使用统计仪器(Student t 检验和 χ²(卡方)检验)。
研究中遇到的肿瘤主要见于成熟的成年和老年男性,通常位于食管下段。其中许多肿瘤的长径在 5 至 10 厘米之间,导致狭窄。它们大多呈浸润性外观,常伴有突出或/和溃疡外观。通常,肿瘤分化不良,处于 III 期。两种主要的 EC 组织学类型表现出不同的形态学特征。文献中的数据显示,研究的形态学参数有时存在广泛的变化范围。我们的结果在这些变化范围内。
总的来说,EC 是侵袭性和晚期诊断的肿瘤,两种主要组织学类型具有明显的形态学和行为特征。与文献数据的比较证实了我们对 EC 及其两种组织学类型的临床和形态学方面的许多观察结果。
