非小细胞肺癌脑转移预后影响因素

目的探讨非小细胞肺癌脑转移的生存情况及预后影响因素。方法选取我院2014年6月至2018年12月确诊139例非小细胞肺癌脑转移患者,收集临床资料并随访生存时间。运用Kaplan-Meier法对每个临床因素的不同水平进行生存分析,Log-rank法进行生存曲线的比较。采用单因素、多因素分析方法来筛选非小细胞肺癌脑转移的预后影响因素。结果本研究139例患者中位生存时间为11.2个月,对症支持组、全脑放疗组、靶向治疗组、全脑放疗+靶向治疗组、全脑放疗+化疗+靶向治疗组分别为8.1个月、10.1个月、14.6个月、16.7个月、23.4个月。单因素分析显示病理类型、发生脑转移的时间、EGFR突变的状态、RPA分级以及治疗方式对非小细胞肺癌脑转移的发生有显著影响作用。多因素分析表明KPS评分、RPA分级、治疗方法、发生脑转移的时间及EGFR突变状态是影响生存期的独立预后因素。结论经积极治疗(化疗+全脑放疗+靶向治疗)脑转移瘤患者可以获得更长生存期,高KPS评分、RPA I级、异时性脑转移及EGFR敏感突变型是非小细胞肺癌脑转移的预后良好因素。     

非小细胞肺癌脑转移的预后因素分析

目的探讨影响非小细胞肺癌脑转移治疗效果的预后因素。方法收集2006年3月-2009年3月在我科接受全脑放射治疗的57例非小细胞肺癌脑转移患者的临床资料,分析影响生存预后的各种因素。结果平均生存期可达到(9.7±2.8)个月。脑转移放疗后复发再次放疗组生存期(11.5月)优于复发后未放疗组(8.7月),无肺、骨转移组生存期(10.1月)优于有肺、骨转移组(8.5月),有显著统计学差异(P0.05)。多因素分析结果显示:脑转移放疗后复发再次放疗,同步放化疗和无肺、骨转移是肺癌脑转移患者的独立预后因素(P0.05)。结论影响非小细胞肺癌脑转移患者预后的主要因素是有无肺内、骨转移、是否采用同步放化疗,脑转移复发后是否再次放疗,选择同步放化疗以及对于脑转移放疗后复发的患者选择再次放疗的治疗方式,可以延长生存。

肺癌脑转移治疗进展

肺癌是最常见的恶性肿瘤,其发病率逐年上升.脑转移是肺癌最常见的转移部位之一,且有增加趋势,脑转移瘤如不治疗,中位生存期为1～3个月.肺癌脑转移以多发转移为主,常伴有颅内压迫症状,危及患者生命,严重影响生存质量.由于大多数化疗药物不能通过血脑屏障,既往放射治疗被认为是有效的治疗方法,但如今临床上很少单用一种治疗方法,而是采用综合治疗方法,如手术治疗联合化疗、手术治疗联合放疗、放化疗结合、靶向治疗等.本文就肺癌脑转移治疗进展作一综述.

Factors affecting the prognosis in patients with primary lung cancer and brain metastases

Brain metastases are frequent features during the course of patients with lung carcinoma. The aim of this study was to investigate prognostic factors for patients with brain metastasis from lung cancer. Eighty-eight patients with brain metastasis from lung cancer were enrolled in the study. Eighty-two of cases were male, six were female and the mean age was 57.5 +/- 10.4 years. The most common symptoms were headache (32.9%) and dizziness (32.9%). Fifty-two (59.1%) patients had solitary brain metastasis and the most frequent metastasing site was parietal lobe (34.1%). The median survival times were 3 months after diagnosis of lung carcinoma and 1.5 months after diagnosis of brain metastasis. Although the absence of brain metastasis at the moment of diagnosis, metachronous metastasis, central localization of the tumour, chemotherapy administration and surgical treatment of brain metastasis are good prognostic factors affecting survival after the diagnosis of lung carcinoma, the positive factors affecting survival after brain metastasis are central localization of tumour, chemotherapy administration and surgical treatment of brain metastasis. In conclusion, performing the combination of cranial radiotherapy, chemotherapy, surgical therapy and supporting therapy should be evaluated in all appropriate patients with brain metastasis from lung cancer.     

Risk and patterns of brain metastases in colorectal cancer

PURPOSE: In patients with colorectal cancer, brain metastasis is infrequent. This study aims to elucidate the risk, pattern of occurrence, and survival time after different treatment modalities. METHODS: A retrospective review of all patients with colorectal cancer admitted to the Veterans General Hospital-Taipei between 1970 and 1996 from our hospital was performed. Univariate analysis for survival determination was performed. RESULTS: Brain metastases developed subsequent to surgery for colorectal cancer in 53 well-documented patients, at a median of 36 months after surgery. Brain metastases were more commonly seen in rectal cancer and often occurred concurrently with lung metastases. Forty of these patients received active intervention in terms of surgery, chemotherapy, or radiotherapy, with surgical intervention achieving a significantly increased mean survival time (+/- standard deviation) compared with chemotherapy or radiotherapy or both of 86.6 +/-17.35 vs. 2.9 +/- 0.59 months (P < 0.05). CONCLUSION: Increased awareness of the possibility of brain metastases, early diagnosis, and aggressive therapy can provide increased survival time for patients with colorectal cancer with brain metastases.     

影响非小细胞肺癌脑转移患者放射治疗后生存的临床相关因素分析

目的 探讨非小细胞肺癌（NSCLC）脑转移患者放射治疗后的预后转归及影响患者生存期的相关因素.方法 回顾性分析2004年1月至2010年11月在我院诊治的NSCLC脑转移放疗后103例患者的资料.采用Kaplan-Meier法进行生存分析,以Log-Rank检验比较各亚组生存率差异,采用风险比例模型（COX模型）进行多因素生存相关危险因素分析.结果 103例NSCLC脑转移放疗后患者总体生存期为1～68个月;中位生存期为10个月（95％CI：7.231～ 12.769个月）,1年生存率为46.0％,2年生存率为22.0％;COX多因素分析结果 显示：体能状态评分（ECOG）、分级预后评估指数（GPA）是影响患者生存率的独立预后因素（P =0.024,P=0.000）.Log-Rank检验行GPA亚组分析显示,4组间生存曲线有显著性差异（P=0.000）.结论 ECOG评分、GPA是影响NSCLC脑转移放疗后患者生存率的独立预后因素;GPA指数模型可以反映放射治疗后NSCLC脑转移患者的预后.     

Surgery in bronchial carcinoma with metastasis

Two groups of lung cancer patients with solitary M₁ disease are presented in whom lung resection was performed at the time of or after operative treatment of the metastasis. Nine patients had solitary brain metastasis prior to the resection of the primary tumor. Six died, with an average survival of 10 months posthoracotomy, 3 survive after 15 to 31 months. The results are less favorable than suggested by the literature where often cases are included which have brain metastasis after lung cancer surgery. Another eight M₁ situations in this series are predominantly lung cancers with pleural disease. Improvement of quality of life and substantial survival times have been observed, though most patients are still at risk after a survival of from 15 to 35 months. As to the histological features, adenocarcinoma was the most frequent type followed by the adenosquamous variant. Lung surgery should be considered in selected cases in spite of known or formerly treated solitary distant metastasis.     

Dramatic response with capecitabine after cranial radiation to the brain parenchymal and leptomeningeal metastases from lung cancer

It is known that the prognosis of Non Small Cell Lung Cancer with brain metastasis are very poor with a median survival of only a few months. Although some chemotherapeutic agents penetrate the blood brain barrier generally chemotherapy results are bad but efficiency may be better after radiotherapy. For this reason brain metastatic disease requires some efforts to improve the response rate. Here we reported a case with lung cancer metastatic to the brain and we discussed the good response to capecitabine after cranial radiotherapy (C).     

Two lung adenocarcinoma patients with multiple brain metastasis treated with Gefitinib and surviving more than 2 years]

Case 1 is a 78-year-old woman in whom lung adenocarcinoma with multiple brain metastasis (cT2N3M1, stage IV) was diagnosed. She was treated with Gefitinib alone. Her lung tumor and metastatic brain lesions decreased 6 months after the start of therapy. She has no recurrence and is still alive with a good performance status after 25 months. Case 2 is an 80-year-old woman in whom lung adenocarcinoma with multiple brain (cT2N3M1, stage IV) was diagnosed. She was also treated with Gefitinib alone and her lung tumor and metastatic brain becomes improved 6 months after the start of therapy. She maintained a good performance status for more than 2 years (29 months). However, 29 months after beginning treatment, she had recurrence in bone and died 2 months later, 31 months after the start of therapy. The prognosis of non-small cell lung cancer with multiple brain metastasis is very poor and the efficacy of chemotherapy for the treatment of multiple brain metastases is limited, and longterm survival remains disappointing. We report two lung adenocarcinoma patients with multiple brain metastasis who survived more than 2 years by treatment with Gefitinib alone.     

Brain metastases as the first symptom of lung cancer: a clinical study from an Asian medical center

Objective

Brain metastasis as the first symptom of lung cancer is a unique clinical entity. We conducted a retrospective study to investigate the clinical characteristics and survival of patients with lung cancer whose first symptom was brain metastases in an Asian population.

Methods

A retrospective study of 186 such patients who had been admitted to one institution in China between January 1, 2003 and December 30, 2008 was performed. The following data were collected and analyzed: manifesting signs and symptoms, imaging studies, extracerebral metastases, initial diagnosis, treatment, and patient survival.

Results

This sample population exhibited high rates of misdiagnosis upon initial presentation (46.8 %). Fifty-seven (30.6 %) patients presented with silent extracerebral metastases. Pathologies among this cohort varied, and adenocarcinomas were most commonly observed. Most patients received surgical resection, and some patients had additional whole-brain radiotherapy or stereotactic radiosurgery. The median survival time for the entire cohort was 15 months (95 % confidence interval, 12.9–17.1 months). Survival rates for 1, 2, and 5 years were 58.2, 34.2, and 6.5 %, respectively. The median survival time was 15, 14, 19, and 7 months for the gross total resection, incomplete resection, surgery + whole-brain radiotherapy, and surgery + stereotactic radiosurgery groups, respectively.

Conclusions

Brain metastasis as the first symptom of lung cancer is a distinct clinical entity. Although overall survival was poor, combined treatments based on surgery for selected patients were reasonable with the exception of a minority who experienced long-term survival.
