To stratify stage IIB (pT4a PN0) colorectal cancer in terms of histopathologic findings.
We reviewed the medical records of 80 patients who underwent surgery for stage IIB colorectal cancer. The disease-free survival (DFS) and overall survival (OS) rates were evaluated and correlated with the presence or absence of "Tumor Necrosis", "Crohn's-like lymphoid reaction", and "Perineural Invasion".
Patients with "Tumor Necrosis" had significantly lower DFS rates (p < 0.0001), those with "Crohn's-like lymphoid reaction" had significantly higher DFS rates (p = 0.037), and those with "Perineural Invasion" had significantly lower DFS rates (p < 0.0001). Patients with "Tumor Necrosis" had significantly lower OS rates (p = 0.016), those with "Crohn's-like lymphoid reaction" had significantly higher OS rates (p = 0.022), and those with "Perineural Invasion" had significantly lower OS rates (p = 0.003).
Since stage IIB colorectal cancers accompanied by the pathological findings of "Tumor Necrosis" and "Perineural Invasion", but with the absence of "Crohn's-like lymphoid reaction" carried a poor prognosis, the efficacy of adjuvant chemoradiation must be considered for these patients.
根据组织病理学结果对IIB期(pT4a PN0)结直肠癌进行分层。
我们回顾了80例接受IIB期结直肠癌手术患者的病历。评估无病生存期(DFS)和总生存期(OS)率,并将其与“肿瘤坏死”、“克罗恩样淋巴反应”和“神经周围侵犯”的有无相关联。
有“肿瘤坏死”的患者DFS率显著较低(p < 0.0001),有“克罗恩样淋巴反应”的患者DFS率显著较高(p = 0.037),有“神经周围侵犯”的患者DFS率显著较低(p < 0.0001)。有“肿瘤坏死”的患者OS率显著较低(p = 0.016),有“克罗恩样淋巴反应”的患者OS率显著较高(p = 0.022),有“神经周围侵犯”的患者OS率显著较低(p = 0.003)。
由于伴有“肿瘤坏死”和“神经周围侵犯”病理表现但无“克罗恩样淋巴反应”的IIB期结直肠癌预后较差,对于这些患者必须考虑辅助放化疗的疗效。
