Lung Cancer Adjuvant Therapy

[Study on the prognosis of the T1a non-small cell lung cancer]

背景与目的

新的第7版非小细胞肺癌（non-small cell Lung cancer, NSCLC）分期已经提出肿瘤直径对NSCLC预后的重要性，但是对癌灶直径≤2 cm预后研究尚少。本研究旨在探讨影响癌灶≤2 cm（T1a）的Ⅰ期NSCLC病人的临床预后因素，为临床预后治疗提供依据。

方法

回顾性分析本院既往手术后病理诊断为癌灶≤2 cm（T1a）的Ⅰ期的73例NSCLC病人，运用统计学软件SPSS 17.0分析影响长期生存的临床因素。

结果

该类患者5年以上总体生存率达到80.8%。性别（P=0.175）、年龄（P=0.241）、病理类型（P=0.265）、是否行系统纵隔淋巴结清扫手术（P=0.918）、是否术后辅助化疗（P=0.616）、是否侵犯胸膜（P=0.827）和该类患者的长期生存无明显相关性。影响预后的主要因素是癌灶的分化程度，即在中度分化程度以下长期生存较差（P=0.01）。

结论

在癌症直径≤2 cm的Ⅰ期肺癌中，侵犯胸膜对生存无影响，而分化程度是一个重要的独立预后因素。

SLP-2 overexpression is associated with tumour distant metastasis and poor prognosis in pulmonary squamous cell carcinoma

OBJECTIVE

To investigate the role of stomatin-like protein 2 (SLP-2), a novel cancer-related gene, in pulmonary squamous cell carcinoma (PSCC) and its implications.

METHODS

Immunohistochemical detection of SLP-2 was performed on 96 cases of PSCC with a tissue microarray.

RESULTS

SLP-2 was overexpressed in lung cancer compared with normal lung tissue (p <0.001). High-level SLP-2 expression was significantly correlated with distant metastasis (p = 0.025), decreased overall survival (p = 0.018) and disease-free survival (p = 0.017). SLP-2 overexpression was an independent prognostic factor in multivariate analysis using the Cox regression model (p <0.05).

CONCLUSION

SLP-2 overexpression is associated with tumour distant metastasis and poor prognosis in PSCC. SLP-2 could be regarded as a new significant prognostic biomarker for patients with PSCC.
