AIM
To examine the depth of tumor invasion and tumor length and assess the clinical impact of the primary tumor score (PTS), based on a combination of tumor invasion and tumor length, in patients with esophageal squamous cell carcinoma (ESCC).
PATIENTS AND METHODS
A total of 237 patients with ESCC were classified into three PTS groups based on cut-off values for deeper tumor invasion (pT2-T4) and greater tumor length (≥44 mm). A PTS of 2 indicated the presence of both of these abnormalities, 1 indicated one of these abnormalities, and 0 indicated neither abnormality.
RESULTS
PTS was significantly positively correlated with depth of tumor invasion, lymph node metastasis, lymphovascular invasion, and stage (all p<0.001). The prognosis differed significantly among the three groups based on PTS (p<0.0001). Multivariate analysis demonstrated that PTS was an independent prognostic factor (p=0.0004).
CONCLUSION
PTS has a clinical utility as a prognostic predictor in patients with ESCC.
目的
探讨食管鳞状细胞癌（ESCC）患者肿瘤浸润深度和肿瘤长度，并评估基于肿瘤浸润和肿瘤长度的原发性肿瘤评分（PTS）的临床影响。
患者与方法
根据更深的肿瘤浸润（pT2 - T4）和更长的肿瘤长度（≥44 mm）的临界值，将237例ESCC患者分为三个PTS组。PTS为2表示存在这两种异常，1表示存在其中一种异常，0表示不存在任何异常。
结果
PTS与肿瘤浸润深度、淋巴结转移、淋巴管浸润和分期均呈显著正相关（均p<0.001）。基于PTS的三组患者预后差异显著（p<0.0001）。多因素分析表明，PTS是一个独立的预后因素（p = 0.0004）。
结论
PTS作为ESCC患者的预后预测指标具有临床应用价值。
