BACKGROUND/AIM: As of 2020, adenocarcinoma arising in the ileocecal valve (ICV-A) has been examined along with cecal and right colon cancer (RCC) under the collective heading "ileocecal" tumor. We propose a new classification system for this cancer.
PATIENTS AND METHODS
We retrospectively analyzed RCC patients from 2003 to 2019. The scheme was: i) Type I cancer for adenocarcinomas residing in ICV; ii) Type II, if they reside 1 to 5 mm from ICV; iii) Type III, 6 mm to 10 mm from ICV; iv) Type IV, at 1,1 to 5 cm; v) Type V, at more than 5 cm (ascending colon cancer).
RESULTS
Of 689 hemicolectomized patients, there were 91 (13.2%) Type I, 87 Type II (12.6%), 38 (5.5%) Type III, 157 (22.8%) Type IV and 314 (45.6%) Type V. Each type was associated with at least one clinicopathologic feature.
CONCLUSION
ICV-A was classified into five types (I-V) according to the distance from ICV. Further studies are needed in order to corroborate our findings.
背景/目的：截至 2020 年，回盲部腺癌（ICV-A）与盲肠癌和右半结肠癌（RCC）一起在“回盲部”肿瘤的标题下进行了检查。我们为此癌症提出了一种新的分类系统。
患者和方法
我们回顾性分析了 2003 年至 2019 年的 RCC 患者。方案如下：i）位于 ICV 的腺癌为 I 型癌症；ii）如果它们位于 ICV 1 至 5mm 处，则为 II 型；iii）如果它们位于 ICV 6 至 10mm 处，则为 III 型；iv）如果它们位于 ICV 1.1 至 5cm 处，则为 IV 型；v）如果它们位于超过 5cm（升结肠癌）处，则为 V 型。
结果
在 689 例半结肠切除术患者中，有 91 例（13.2%）为 I 型，87 例（12.6%）为 II 型，38 例（5.5%）为 III 型，157 例（22.8%）为 IV 型，314 例（45.6%）为 V 型。每种类型都与至少一种临床病理特征相关。
结论
根据与 ICV 的距离，ICV-A 被分为五型（I-V）。需要进一步的研究来证实我们的发现。
