Ⅳ期非小细胞肺癌预后影响因素分析

Objective: To investigate the prognostic factors for stage Ⅳ non-small cell lung cancer (NSCLC) with distant metastasis and establish a reliable model of clinical prognostic index.Methods: From January 1990 to April 2005,313 primary NSCLC patients with metastasis,who had been treated in Shanghai Chest Hospital,were reviewed.Survival time was estimated according to the Kaplan-Meier method.Cox proportional hazard regression model was used for multivariate analysis.Results: Among the 313 cases of non-small cell lung cancer (NSCLC) at stage Ⅳ,there were 218 and 95 patients with metastasis to single and different organs,respectively.The overall median survival time for all 313 cases of NSCLC patients was 10.8 (9.00,12.30)months and the overall 1-,2-,3-,4- and 5-year survival rate was 45%,18%,12%,4% and 0%.There were 63,174,127,36,18,11 and 5 patients with metastasis to brain (20.13%),bone (55.59%),lung (40.58%),liver (11.50%),adrenal gland (5.75%),subcutaneous (3.51%) and others,respectively.The survival time was shortest in subcutaneous metastasis (4.6 months),and liver 7.0 months,brain 8.0 months,adrenal gland 8.6 months,bone 10.6 months,lung 11.8 months.Kaplan-Meier estimation showed that patients anatomic typing,KPS,numbers of organ with metastasis,appetite,liver,adrenal gland and subcutaneous metastasis,body weight loss,smoking,index of smoking,chemotherapy,cycles of chemotherapy were the predictors of survival.Multivariate analysis showed survival statistically significant correlation with anatomic typing,KPS,appetite,liver and subcutaneous metastasis,body weight loss,cycles of chemotherapy.The relative risk (RR) was 1.51,1.97,1.55,1.67,2.56,and 2.56 respectively.Conclusion: Survival time decreases distinctly in patients who had distant metastasis to more than two different organs (P＜0.01).Bone is the commonest organ for distant metastasis in lung cancer.The prognosis is poor when lung cancer appears subcutaneous metastasis and liver metastasis.Independent prognostic factors in patient with stage Ⅳ non-small cell lung cancer were liver and subcutaneous metastasis,anatomic typing,KPS,appetite,body weight loss,cycles of chemotherapy.     

非小细胞肺癌寡转移的立体定向放射治疗研究

非小细胞肺癌(Non-small cell lung cancer,NSCLC)是除小细胞肺癌以外所有类型的肺癌,脑、骨、肝及肾上腺为最常见的远处转移部位。在NSCLC远处转移患者中,并非都是多发的、广泛的,有近7%的患者表现为肺外孤立性转移。这种特殊形式的晚期肿瘤转移状态称之为NSCLC寡转移。寡转移的治疗以局部治疗为主,局部治疗主要措施包括立体定向放疗、手术切除、射频消融等。本文主要探讨立体定向放射治疗(Stereotactic radiotherapy,SRT)对NSCLC在常见远处转移脏器寡转移的作用。     

Pretreatment prognostic factors in patients with early-stage (I/II) non-small-cell lung cancer treated with hyperfractionated radiation therapy alone

PURPOSE: To investigate influence of various pretreatment prognostic factors in patients with early stage (I/II) non-small-cell lung cancer (NSCLC) treated with hyperfractionated radiation therapy alone. PATIENTS AND METHODS: One hundred and sixteen patients were treated with tumor doses of 69.6 Gy, 1.2-Gy, twice-daily fractionation. There were 49 patients with Stage I and 67 patients with Stage II. Eighty patients had Karnofsky performance status (KPS) 90-100 and 95 patients had <5% weight loss. Peripheral tumors were observed in 57 patients. Squamous histology was observed in 70 patients and the majority of patients had concomitant disease (n=72). RESULTS: The median survival time for all patients was 29 months; 5-year survival was 29%. The median time to local progression and the distant metastasis were not achieved, whereas 5-year local progression-free and distant metastasis-free survivals were 50% and 72%, respectively. Multivariate analysis identified KPS, weight loss, location, histology, and the reason for not undergoing surgery as prognostic factors for survival. KPS, location, and histology influenced local progression-free survival, whereas only KPS and weight loss influenced distant metastasis-free survival. CONCLUSIONS: This retrospective analysis identified KPS and weight loss as the most important prognostic factors of outcome in patients with early-stage NSCLC treated with hyperfractionation radiation therapy.     

1,742例Ⅳ期非小细胞肺癌的预后分析

背景与目的目前非小细胞肺癌(non-small cell lung cancer,NSCLC)仍是导致癌症死亡的首要原因,本研究旨在探讨影响晚期NSCLC预后的重要因素。方法收集2000年1月4日-2008年12月25日1,742例IV期NSCLC临床资料,所有病例经细胞学或组织病理学确诊。分析性别、年龄、吸烟史、病理类型、分型、临床TN分期、转移器官数目、治疗方法对预后的影响,应用Kaplan-Meire方法计算生存率,Log-rank检验生存率差别,采用Cox多因素回归对预后因素进行分析。结果本组1,742例患者的中位生存期为10.0个月(9.5个月-10.5个月),1年、2年、3年、4年、5年生存率分别为44%、22%、13%、9%、6%。单器官发生转移与多器官转移中位生存期分别为11个月vs7个月(P<0.001)。不同器官发生转移后生存期不同,中位生存期分别为肺12个月(11.0个月-12.9个月),骨9个月(8.3个月-9.6个月),脑8个月(6.8个月-9.1个月),肝、肾上腺、远处淋巴结转移均为5个月(3.8个月-6.1个月),皮下3个月(1.7个月-4.3个月)。腺癌患者1,086例(62%),鳞癌305例(17.5%),中位生存期分别为12个月vs8个月(P<0.001)。化疗与最佳支持治疗者中位生存期分别为11个月vs6个月(P<0.001)。放疗与否的中位生存期分别为11个月vs9个月(P=0.017)。结论性别、年龄、大体分型、病理类型、临床T分期、N分期、转移器官数目、吸烟史、治疗方法是晚期NSCLC预后的独立影响因素。     

FDG-PET-detected extracranial metastasis in patients with non-small cell lung cancer undergoing staging for surgery or radical radiotherapy--survival correlates with metastatic disease burden

The prognostic significance of extracranial distant metastasis detected by positron emission tomography (PET) was investigated in patients with non-small cell lung cancer (NSCLC). Forty-two patients staged with 18 F-fluorodeoxyglucose-PET-detected distant metastasis before planned surgery (n=7) or radical radiotherapy (RT)/chemoradiotherapy (n=35) for NSCLC were identified from a prospective database. The influence of metastasis number and other prognostic factors was investigated using Cox's regression analysis. Treatment after PET included surgery (n=2), radical RT (n =5), palliative RT (n=25), chemotherapy (n=8) or supportive care (n=2). All but 4 patients had died by the last follow-up. Median survival was 9 months overall, 12 months for 27 patients with single PET-detected metastasis and 5 months for 15 patients with >1 metastasis (p=0.009). It was found that the Eastern Cooperative Oncology Group performance status (p=0.027) but not pre-PET stage, weight loss or metastasis site correlated with survival. PET-detected metastatic tumor burden appeared to influence survival and should be evaluated as a prognostic factor in NSCLC.

Clinical model to predict survival in chemonaive patients with advanced non-small-cell lung cancer treated with third-generation chemotherapy regimens based on eastern cooperative oncology group data.

PURPOSE: (1) Identify clinical factors that can be used to predict survival in chemotherapy-naive patients with advanced non-small-cell lung cancer (NSCLC) treated with third-generation chemotherapy regimens, and (2) build a clinical model to predict survival in this patient population. PATIENTS AND METHODS: Using data from two randomized, phase III Eastern Cooperative Oncology Group (ECOG) trials (E5592/E1594), we performed univariate and multivariate stepwise Cox regression analyses to identify survival prognostic factors. We used 75% of randomly sampled data to build a prediction model for survival, and the remaining 25% of data to validate the model. RESULTS: From 1993 to 1999, 1,436 patients with stage IV or IIIB NSCLC with effusion were treated with platinum-based doublets (involving either paclitaxel, docetaxel, or gemcitabine). The response rate and median survival time were 20% and 8.2 months, respectively. One- and 2-year survivals were 33% and 11%, respectively. In multivariate analysis, six independent poor prognostic factors were identified: skin metastasis (hazard ratio [HR], 1.88), lower performance status (ECOG 1 or 2; HR, 1.46), loss of appetite (HR, 1.62), liver metastasis (HR, 1.32), >/= four metastatic sites (HR, 1.20), and no prior surgery (HR, 1.16). A nomogram using six pretreatment prognostic factors was built to predict 1- and 2-year survival. CONCLUSION: Six pretreatment factors can be used to predict survival in chemotherapy-naive NSCLC patients treated with standard chemotherapy. Using our prognostic nomogram, 1- and 2-year survival probability of NSCLC patients can be estimated before treatment. This prognostic model may help clinicians and patients in clinical decision making, as well as investigators in research planning.     

FDG uptake correlates with recurrence and survival after treatment of unresectable stage III non-small cell lung cancer with high-dose proton therapy and chemotherapy

ABSTRACT: BACKGROUND: We studied whether maximum standardized uptake values (SUV) from [18F] PET/CT predict clinical outcome after concurrent proton/chemotherapy for stage III non-small cell lung cancer (NSCLC). METHODS: Eighty-four patients were treated prospectively with 74 Gy(RBE) proton therapy and concurrent chemotherapy. PET/CT scans were available before (SUV1) and within 6 months after (SUV2) treatment. The predictive value of clinical and PET/CT factors were analyzed with univariate and multivariate Cox regression models. RESULTS: Median survival time was 29.9 months. At 3 years, the local recurrence-free survival (LRFS) rate was 34.8%; distant metastasis-free survival (DMFS), 35.4%; progression-free survival (PFS), 31.2%; and overall survival (OS), 37.2%. Patients with SUV2 [greater than or equal to] 3.6 (the median) had high rates of LR (p = 0.021). Of 12 clinicopathologic features evaluated in univariate analysis, only KPS, SUV1, and SUV2 predicted LRFS, DMFS, PFS, and OS (p <0.05). Multivariate analysis showed that KPS (p = 0.025) and SUV2 (p = 0.017) were independently prognostic for LRFS and that SUV1, SUV2, and KPS were independently prognostic for DMFS, PFS, and OS (p <0.05). CONCLUSIONS: SUV2 predicted LRFS, and SUV1 and SUV2 predicted DMFS, PFS, and OS, in patients with stage III NSCLC treated with concurrent chemotherapy and high-dose proton therapy.     

Ⅰ期非小细胞肺癌预后因素的研究

目的 探讨Ⅰ期非小细胞肺癌(NSCLC)的联合预后因素。方法 回顾性分析58例Ⅰ期NSCLC患者的临床资料、术后病理结果和免疫组化技术检测的9项基因表达指标(c-myc、MDM2、c-erbB-2、EGFR、p53、p14^ARF、p16^INK4、p21^WAF1、nm23)。观察患者的总生存率、局部区域性复发率和远处转移率。结果 全组5年生存率、局部区域性复发率和远处转移率分别为71．1％,11．1％和33．5％。单因素分析结果表明,肿瘤细胞的低分化是影响总生存率的不良预后因素(P=0.028);c—myc与c-erbB-2的高表达均为影响总生存率和远处转移率的不良预后因素;促进肿瘤增殖基因总分组的高分值(P=0．041)与综合肿瘤基因组的高分值(P=0．006),是总生存率的不良预后因素。多因素分析结果表明,肿瘤细胞的分化程度与综合肿瘤基因的联合表达,是影响总生存率的独立预后因素。本组结果还显示,已行化疗的高危组患者,其总生存率与无远处转移率均优于未行化疗者,但差异尚未见有显著性。结论 肿瘤细胞的分化程度与综合肿瘤基因的表达,可能是Ⅰ期NSCLC的预后因素。高危组患者进行术后化疗似有提高疗效的趋势。     

晚期小细胞肺癌和非小细胞肺癌不同转移部位预后意义的比较

  目的  明确不同转移部位对小细胞肺癌（small cell lung cancer,SCLC）和非小细胞肺癌（non-small cell lung cancer,NSCLC）预后影响的差异。  方法  回顾性分析天津医科大学肿瘤医院2012年1月至2017年12月确诊为晚期SCLC 266例和2015年1月至2017年12月确诊为晚期NSCLC 275例,总计541例患者病例资料。主要观察指标为总生存期（overall survival,OS）。  结果  在SCLC中,与多器官转移者相比,单器官转移者的预后更好（P=0.000 4）;在NSCLC中,单器官与多器官转移者之间未见到明显的生存差异（P=0.451）。在SCLC单器官转移者中,脑转移的预后相对最好,骨转移的预后相对较差,肝转移的预后最差,三者的中位生存时间（median survival time,MST）分别为14.5、11.5和10.3个月;在NSCLC单器官转移者中,肺内转移的预后最佳,肝和肾上腺转移者的预后较差,三者的MST分别为未达到、7.6和7.3个月。在SCLC多器官转移者中,有骨（P=0.046）、肝（P=0.019）转移者预后较差;而有无脑（P=0.995）、肺（P=0.847）、肾上腺（P=0.255）转移对患者的预后无显著性影响;在NSCLC多器官转移的患者中,有脑（P=0.054）、肾上腺转移（P=0.006）的患者预后较差;有肺（P=0.008）转移的患者预后较好;而有无骨（P=0.091）、肝（P=0.300）转移对患者的预后无显著性影响。  结论  不同转移部位对SCLC和NSCLC预后的影响存在差异。      

Long-term survival in patients with synchronous, solitary brain metastasis from non-small-cell lung cancer treated with radiosurgery

PURPOSE: To report the outcome of patients with synchronous, solitary brain metastasis from non-small-cell lung cancer (NSCLC) treated with gamma knife stereotactic radiosurgery (GKSRS). PATIENTS AND METHODS: Forty-two patients diagnosed with synchronous, solitary brain metastasis from NSCLC were treated with GKSRS between 1993 and 2006. The median Karnofsky performance status (KPS) was 90. Patients had thoracic Stage I-III disease (American Joint Committee on Cancer 2002 guidelines). Definitive thoracic therapy was delivered to 26/42 (62%) patients; 9 patients underwent chemotherapy and radiation, 12 patients had surgical resection, and 5 patients underwent preoperative chemoradiation and surgical resection. RESULTS: The median overall survival (OS) was 18 months. The 1-, 2-, and 5-year actuarial OS rates were 71.3%, 34.1%, and 21%, respectively. For patients who underwent definitive thoracic therapy, the median OS was 26.4 months compared with 13.1 months for those who had nondefinitive therapy, and the 5-year actuarial OS was 34.6% vs. 0% (p < 0.0001). Median OS was significantly longer for patients with a KPS >or=90 vs. KPS < 90 (27.8 months vs. 13.1 months, p < 0.0001). The prognostic factors significant on multivariate analysis were definitive thoracic therapy (p = 0.020) and KPS (p = 0.001). CONCLUSIONS: This is one of the largest series of patients diagnosed with synchronous, solitary brain metastasis from NSCLC treated with GKSRS. Definitive thoracic therapy and KPS significantly impacted OS. The 5-year OS of 21% demonstrates the potential for long-term survival in patients treated with GKSRS; therefore, patients with good KPS should be considered for definitive thoracic therapy.     

546例Ⅳ期非小细胞肺癌远处转移特点的放疗意义分析

目的 分析初诊临床Ⅳ期非小细胞肺癌的远处转移特点,为局部三维放疗可能性提供参考。方法 回顾分析 546例临床Ⅳ期非小细胞肺癌初诊时远处转移器官、病灶部位、数目等特点,以及肿瘤分期对远处转移率的影响。结果 546例患者中骨、脑、肺、肝、肾上腺、远处淋巴结、皮下、其他器官转移分别为294、167、137、79、66、37、35、10例。单器官转移 379例,其中骨、脑、肺、肝、肾上腺、远处淋巴结、皮下、其他器官转移分别占37.7%、19.8%、16.9%、7.4%、7.4%、4.5%、5.5%、0.8%。T₃₊₄期骨转移率与T₁₊₂期的差异无统计学意义(69.4%、30.6%,χ²=7.65,P=0.067),而N₂₊₃的显著高于N₀₊₁(69.7%、30.3%,χ²=7.89,P=0.044)。T₃₊₄期脑转移率显著高于T₁₊₂期的(70.7%、29.3%,χ²=10.64,P=0.018),而N₂₊₃期与N₀₊₁期的差异无统计学意义(54.5%、45.5%,χ²=7.14,P=0.079),但N₁₊₂₊₃期的显著高于N₀期的(86.8%、13.2%,χ²=10.26,P=0.024)。结论 Ⅳ期非小细胞肺癌初诊时远处转移率由高到低依次为骨、脑、肺、肝、肾上腺和其他器官并以单器官多见;局部病灶分期越晚远处转移率越高;提示三维放疗技术可用于改善部分Ⅳ期NSCLC患者生活质量并延长生存时间。     

非小细胞肺癌脑转移放射治疗的预后因素分析

背景与目的脑转移最常见于肺癌患者,放射治疗是其有效的常规治疗手段。目前的治疗以姑息止痛和减轻症状为目的,方法差异较大,对肺癌脑转移预后的认识也不尽相同。本研究旨在分析非小细胞肺癌脑转移患者放射治疗的疗效以及影响生存率的预后因素并建立预后模型。方法回顾性分析1995年2月-2006年10月在我科接受全脑放射治疗的82例非小细胞肺癌脑转移患者的临床资料,采用Kaplan-Meier法计算生存率,各亚组生存率差别的比较采用log-rank时序检验,分析影响生存预后的各种因素(单因素和多因素分析),以Cox回归分析获得的有统计学意义的因子组成预后模型。结果随访时间为1-120个月,全组患者诊断脑转移后的中位生存期为10.5个月,6个月、1年和2年的总生存率分别为50.8%、23.7%和5.1%。单因素和多因素分析均显示放射治疗前KPS评分、肺原发肿瘤控制情况、确诊肺癌到脑转移间隔时间、脑转移灶数目是影响生存的独立预后因素,根据上述因素建立预后指数将82例患者分成预后好、中和差三组,其生存曲线的差异有统计学意义(P<0.001)。结论KPS评分、确诊肺癌到脑转移间隔时间、肺原发肿瘤控制情况、脑转移灶数目是影响非小细胞肺癌脑转移放射治疗生存的独立预后因素,预后指数模型能很好地反映预后。     

Results of a surgical resection for patients with stage IV non--small-cell lung cancer

PurposeThis study retrospectively investigated the clinical significance of surgical treatment for stage IV non–small-cell lung cancer (NSCLC).SubjectsThere were 36 patients who underwent surgical resection for stage IV NSCLC between 1999 and 2008.ResultsThe patients included 22 males and 14 females. All patients had either synchronous distant metastasis or pleural dissemination. The mean age of the patients was 65.8 years (range, 18 to 90 years). The histological types included 29 adenocarcinomas, 5 squamous-cell carcinomas and 2 large-cell carcinomas. The organs of metastasis were bone in 5 patients, brain in 4, adrenal gland in 4, axillary lymph nodes in 3, liver in 2, and 1 patient had a contralateral pulmonary metastasis. The number of metastases was one site in 13, two sites in 3, three sites in 1, and five sites in 2 patients. The patients with bone metastasis were treated with radiation, and the patients with brain metastasis underwent stereotaxic radiosurgery. The patients with either adrenal metastasis, axillary lymph node metastasis, or contralateral lung metastasis underwent surgical resection. Among the patients with distant metastasis, the 5-year survival rate was 30.1 %. There were 17 patients with pleural dissemination. The 5-year survival rate in these patients was 25.3%. The overall 5-year survival rate after surgery in the patients with stage IV disease was 26.8%.ConclusionSelected patients who can undergo surgical resection for the primary tumor and effective local therapy for metastatic lesions still have a chance to obtain long-term survival. Surgical treatment for NSCLC with oligometastatic disease can be considered as one arm of multidisciplinary treatment.     

Prognostic factors in advanced non-small cell lung cancer: elevated serum levels of neuron specific enolase indicate poor prognosis

BACKGROUND: Non-small cell lung cancer (NSCLC) is resistant to chemotherapy and prognosis of advanced NSCLC patients is considered to be dependent on various prognostic factors. METHODS: We analyzed prognostic factors in patients with advanced NSCLC who had been enrolled in clinical trials conducted by the Okayama Lung Cancer Study Group between 1978 and 1992 using two kinds of multivariate analysis, Cox's multivariate analysis and recursive partitioning and amalgamation (RPA) analysis. RESULTS: The first analysis was performed on 261 patients using 28 variables. Performance status (PS), clinical stage, liver metastasis or serum albumin level was an independent prognostic factor by Cox's analysis. In the second analysis performed on 128 patients having data on neuron specific enolase (NSE), NSE was the most important prognostic factor. Using the RPA method, three subgroups with significantly different survival potentials were defined. Among them, patients with normal serum NSE levels and good PS were found to obtain a markedly favorable prognosis [median survival time (MST) 22.1 months, 3-year survival rate 42.9%], whereas the survival of patients with elevated serum NSE levels and bone metastasis was extremely short (MST 4.7 months, 3-year survival rate 0%). CONCLUSIONS: These results indicate that analysis of prognostic factors including serum levels of NSE is useful for predicting the survival of patients with advanced NSCLC.

螺旋断层放疗治疗转移性非小细胞肺癌的预后分析

目的 探讨转移性非小细胞肺癌（NSCLC）患者接受螺旋断层放疗后的预后情况及其影响因素。方法 对本院2011年6月至2013年2月采用螺旋断层放疗技术治疗的51例转移性NSCLC患者的临床资料进行回顾性分析。所有靶区的中位放疗剂量为42.5 Gy（30～62 Gy）,单次放疗的中位剂量2 Gy（1.8～3 Gy）。应用Kaplan-Meier法计算生存率,Log-rank检验比较组间的生存差异,Cox风险比例回归模型分析影响预后的各种因素。结果 所有患者随访时间均超过1年。51例转移性NSCLC患者的中位生存时间为19.3个月,1年生存率为64.7％。单因素分析显示,KPS评分高、病理类型为腺癌、放疗前接受过化疗、无肝转移和所有病灶计划靶区体积（PTV）≤1300 cm³是NSCLC患者预后良好的影响因素（P＜0.05）;Cox多因素分析显示KPS评分、放疗前是否化疗和所有病灶PTV是转移性NSCLC患者采用螺旋断层放疗的独立预后因素。结论 转移性NSCLC采用螺旋断层放疗对延长患者的生存时间及改善预后可能有重要意义。     

影响晚期肺鳞癌一线化疗疗效的临床因素分析

目的:分析影响铂二联方案一线治疗晚期肺鳞癌的临床因素,为一线治疗提供临床依据。方法:回顾性分析2008年6月至2012年12月109例经病理及影像学检查确诊、一线应用铂二联方案化疗的IV期肺鳞癌患者的临床因素,包括:性别、年龄、是否吸烟、是否存在远处转移、一线化疗方案、一线方案的疗效及周期数、是否接受局部放疗及二线治疗;分析这些临床因素对一线方案近期及远期疗效的影响。近期疗效用客观有效率代表,远期疗效用中位生存期代表。结果:109例患者中,部分缓解者35例,疾病稳定者34例,疾病进展者40例,客观有效率 32.1%,疾病控制率 63.3%。中位生存期为12.00个月（95%CI:11.05~12.95个月）,一线治疗中位至疾病进展时间为5.0个月（95%CI:4.26~5.74个月）。单因素分析表明患者性别、年龄、是否吸烟、是否存在远处转移、一线方案对一线化疗疗效的影响不具有统计学意义。Kaplan-Meier分析及COX回归分析均表明:性别、年龄、是否吸烟、治疗前是否存在远处转移以及一线方案对患者生存期的影响不具有统计学意义;而一线化疗疗效、一线化疗周期数、是否接受局部放疗及二线治疗则对患者生存期的影响具有统计学意义。结论:一线化疗的疗效及周期数、是否接受二线治疗及局部放疗是影响晚期肺鳞癌患者预后的独立因素。
