Conventional clinicopathologic prognostic factors in surgically resected nonsmall cell lung carcinoma. A comparison of prognostic factors for each pathologic TNM stage based on multivariate analyses

BACKGROUND: A number of prognostic factors have been reported for resected nonsmall cell lung carcinoma. None of them, however, has been reported to have greater prognostic impact than the pathologic TNM staging system. The authors evaluated 18 conventional clinicopathologic prognostic factors in each pathologic stage. METHODS: A retrospective study was conducted on surgically resected 836 lung carcinoma patients, and the following conventional prognostic factors were evaluated in multivariate analyses: age, gender, pack-year smoking, serum carcinoembryonic antigen and squamous cell carcinoma antigen levels, laterality of tumor, clinical N status, histologic type of tumor, greatest tumor dimension, grade of differentiation, pleural involvement, lymphatic invasion, vascular invasion, degree of fibrosing scarring, nuclear atypia, mitotic activity, and curativity of resection. RESULTS: The overall 5-year survival rate was 63.8%. In 430 cases of pathologic Stage I disease, multivariate analyses revealed 3 significant prognostic factors: clinical N status (P < 0.001), vascular invasion (P = 0.001), and curativity of resection (P < 0.001). In 406 cases of more advanced disease, i.e., pathologic Stage II, IIIA, IIIB, or IV, multivariate analyses revealed 4 factors as significant: histology (P = 0.001), pathologic N status (P < 0.001), tumor size (P < 0.001), and curativity of resection (P = 0.002). CONCLUSIONS: Conventional clinicopathologic prognostic factors had a different impact on prognosis in each pathologic TNM stage among patients who underwent surgical resection of nonsmall cell lung carcinoma. These factors should be analyzed separately in each pathologic TNM stage.

Characteristics of lung cancer in Korea, 1997

The high proportion of smokers and the incidence of advanced, unresectable lung cancer in Korea were examined to aid the development of a national anti-smoking program and the early detection of lung cancer. Koreans are a single racial group with a high smoking rate among men and a contrastingly low smoking rate among women. This report documents a retrospective investigation conducted by The Korean Academy of Tuberculosis and Respiratory Disease into the characteristics of all lung cancers diagnosed between 1 January 1997 and 31 December 1997 in Korea. Among the 3794 patients included in this study, 76.8% were smokers and, in particular, 89.8% of the males were smokers. Squamous cell carcinoma was the most frequent type of lung cancer encountered (44.7%), followed by adenocarcinoma (27.9%). The smoking rate in the case of adenocarcinoma was significantly lower than that found in both squamous cell carcinoma and small cell cancer. The most common symptom was a cough. Only 7.2% of patients were asymptomatic. Bronchoscopic biopsy has a primary role in the diagnosis of squamous cell carcinoma and small cell cancer, but percutaneous needle biopsy has a more important role in the case of adenocarcinoma. Two-thirds of the nonsmall cell lung cancer patients were detected in the unresectable advanced stages (IIIB and IV). In contrast to other countries, squamous cell carcinoma is still the most frequent type of lung cancer in Korea. The high proportion of smokers and the incidence of advanced, unresectable lung cancer at diagnosis have urged development of a national anti-smoking program to promote the cessation of smoking and the early detection of lung cancer.     

IGF1R和IGFBP3在肺鳞癌中的表达及其临床意义

目的:检测IGF1R、IGFBP3在肺鳞癌组织中的表达,并探讨其在肺鳞癌发生发展中的作用及其临床意义。方法:用免疫组化二步法检测246例肺鳞癌术后组织与40例癌旁正常组织中IGF1R、IGFBP3的表达情况,并分析二者的相关性及与临床病理特征和预后的关系。结果:IGF1R在肺鳞癌组织中的阳性表达明显高于癌旁正常组织,其表达率分别为54.07%、32.5%,IGFBP3在肺鳞癌组织中的阳性表达明显低于癌旁正常组织,其表达率分别为61.79%、87.5%,差异具有统计学意义（P＜0.05）。IGF1R的表达与淋巴结转移正相关（P＜0.05）,IGFBP3的表达与肺癌的TNM分期、淋巴结转移负相关（P＜0.01）,而与其他临床病理参数无关（P＞0.05）。IGF1R阳性表达组患者生存期明显短于IGF1R阴性表达组患者,IGFBP3阳性表达组患者生存期明显长于IGFBP3阴性表达组患者,差异有统计学意义（P分别为<0.001和=0.001）。Cox单因素分析显示TNM分期、淋巴结转移、IGF1R及IGFBP3的表达均与预后相关,将TNM分期、淋巴结转移、IGF1R及IGFBP3的表达进行Cox回归多因素分析,结果显示TNM分期、IGF1R及IGFBP3的表达均为肺鳞癌患者的独立预后因子。IGF1R、IGFBP3在肺鳞癌组织中表达呈负相关（r=-0.204,P＜0.001）。结论:IGF1R、IGFBP3参与了肺鳞癌的发生、发展,并且二者均为肺鳞癌的独立预后因子。有望成为分子靶向治疗的新靶点。     

Aberrant methylation of the FHIT gene in chronic smokers with early stage squamous cell carcinoma of the lung

Fragile histidine triad (FHIT) gene plays an important role in the pathogenesis of lung cancer. However, the clinicopathological significance of CpG island hypermethylation of FHIT gene in non-small cell lung cancer (NSCLC) remains to be elucidated. We studied FHIT methylation in 254 NSCLCs in order to further understand the clinicopathological and prognostic significance of FHIT methylation in NSCLC. Methylation status of the FHIT gene was examined using Methylation-Specific PCR. All statistical analyses were two-sided, with a 5% type I error rate. Hypermethylation of the FHIT gene occurred more frequently in squamous cell carcinoma than adenocarcinoma. For 93 adenocarcinomas there was no statistically significant association between FHIT methylation and age, gender, smoking history, pathologic stage and p16 methylation. However, FHIT methylation in 125 squamous cell carcinomas was associated with exposure to tobacco smoke and p16 methylation, but not with age, gender and pathologic stage. Hypermethylation of FHIT in squamous cell carcinomas occurred more frequently in current smokers (45%) than in never-smokers (13%). FHIT methylation was significantly associated with p16 methylation in current- and ex-smokers (P = 0.02 and P = 0.01, respectively) with squamous cell carcinoma and in patients with pathologic stage I squamous cell carcinoma (P = 0.001). Patients with p16 methylation were 3.74 times [95% confidence interval (CI) = 1.62 - 7.95; P = 0.001] more likely to have FHIT methylation in squamous cell carcinoma. FHIT methylation in squamous cell carcinoma occurred at a 4.62 times (95% CI = 1.26 - 34.97; P = 0.02) higher prevalence in current smokers than in never-smokers. No prognostic effect of FHIT methylation was observed in stage I and stage II NSCLCs. In conclusion, hypermethylation of the FHIT gene did not have a prognostic significance in early stage NSCLCs. The FHIT methylation is associated with the p16 methylation and smoking in squamous cell carcinoma, suggesting that FHIT may cooperate with p16 for the development of squamous cell carcinoma of lung in individuals exposed to tobacco smoke.     

食管鳞癌患者远处转移部位与预后的相关性及生存分析

目的:探讨食管鳞癌患者远处转移部位与预后的相关性及生存分析。方法:从SEER数据库中提取2010年至2015年共439例食管鳞癌伴远处转移患者的临床资料,回顾性分析比较食管鳞癌远处转移部位与预后的相关性,通过χ2检验比较两组变量的差异,采用Kaplan-Meier法绘制生存曲线,Log-rank检验进行单因素分析,COX回归进行多因素分析。结果:肺转移、骨+肺转移、肝+肺转移患者预后较好;骨转移、脑转移、骨+脑转移、骨+脑+肝+肺转移患者预后较差。单因素分析显示:年龄、原发灶部位、T分期、手术情况、多器官转移情况与食管鳞癌远处转移患者的预后有关（P＜0.05）;多因素分析显示:年龄、手术情况与多器官转移情况是影响食管鳞癌远处转移患者总生存时间（OS）的独立危险因素。结论:食管鳞癌伴远处转移的患者整体预后较差,但年龄在60~69岁区间、接受手术治疗与较好的预后相关。仅单器官转移的食管鳞癌患者中,骨转移、脑转移患者预后较差;合并多器官转移的患者中,骨+脑转移、骨+脑+肝+肺转移患者预后较差。     

肺鳞癌的个体化治疗进展

鳞状细胞肺癌(SqCLC)是非小细胞肺癌(non-small cell lung cancer，NSCLC)的一种独特的组织学亚型，尤其是晚期鳞癌，由于其特殊的临床病理特征，相对于肺腺癌可选择的治疗药物少，不良反应也大，因此肺鳞癌预后比肺腺癌差。近年来，随着化疗药物的改进，靶向药物的研发，尤其是免疫治疗的重大突破，治疗肺鳞癌有了更多的选择，肺鳞癌也走向了个体化治疗。     

Squamous and small cell carcinomas of the lung: similarities and differences concerning the role of tobacco smoking

In the time period 1988-2000, a case-case study on environmental factors and lung cancer risk was conducted in Montevideo, Uruguay. This study was designed in order the establish possible differences between squamous cell carcinomas (SCC) and small cell carcinomas (SCLC) of the lung in relation to tobacco smoking. Three hundred and ninety one (391) patients with small cell carcinoma were compared with 1187 patients with squamous cell carcinoma. Regarding sex, the study included a small number of women (26 with SCLC and 20 with SCC). SCLC was associated with higher risks for smoking status, smoking intensity and cumulative exposure to tobacco smoking when compared with SCC. These three tobacco variables were significantly different between both cell types in men. Smoking duration was significantly higher among SCLC compared with SCC only in women. With decreasing age at starting to smoke, the proportion of SCLC increases at the expense of SCC. Finally, types of tobacco and cigarette were not different between cell types in both sexes. It should be noted that these tobacco variables were not associated with increased risks among SCC, when this cell type was compared with SCLC. These results suggests that SCLC display the strongest relation with tobacco smoking than SCC.
