肺癌是我国北方最常见的恶性肿瘤,部分甚至以颈部淋巴结转移为首发症状.因此准确判断颈部淋巴结的转移情况,对肺癌诊断确定,指导化疗、放疗及估计预后等具有重要意义.本研究对随机选择的103例首诊肺癌患者行超声检查,并对243个可疑颈部淋巴结行细针穿刺针吸细胞学检查(fine needle aspiration cytopathology,FNAC),旨在探讨超声对肺癌颈部淋巴结转移的诊断价值.  相似文献

We aimed to evaluate prospectively the efficacy of positron emission tomography (PET)/computed tomography (CT) plus brain magnetic resonance imaging (MRI) for detecting extrathoracic metastases in lung adenocarcinoma. Metastatic evaluations were feasible for 442 consecutive patients (M:F=238:204; mean age, 54 yr) with a lung adenocarcinoma who underwent PET/CT (CT, without IV contrast medium injection) plus contrast-enhanced brain MRI. The presence of metastases in the brain was evaluated by assessing brain MRI or PET/CT, and in other organs by PET/CT. Diagnostic efficacies for metastasis detection with PET/CT plus brain MRI and with PET/CT only were calculated on a per-patient basis and compared from each other. Of 442 patients, 88 (20%, including 50 [11.3%] with brain metastasis) had metastasis. Regarding sensitivity of overall extrathoracic metastasis detection, a significant difference was found between PET/CT and PET/CT plus brain MRI (68% vs. 84%; P=0.03). As for brain metastasis detection sensitivity, brain MRI was significantly higher than PET/CT (88% vs. 24%; P<0.001). By adding MRI to PET/CT, brain metastases were detected in additional 32 (7% of 442 patients) patients. In lung adenocarcinoma patients, significant increase in sensitivity can be achieved for detecting extrathoracic metastases by adding dedicated brain MRI to PET/CT and thus enhancing brain metastasis detection.  相似文献

Breast cancer that has metastasized to the brain presents difficult clinical challenges. This diagnosis comes with high mortality rates, largely due to complexities in early detection and ineffective therapies associated with both dormancy and impermeability of the blood–brain barrier (BBB). Magnetic resonance imaging (MRI) is the current gold standard for diagnosis and assessment of brain tumors. It has been used clinically to investigate metastatic development as well as monitor response to therapy. Here, we describe preclinical imaging strategies that we have used to study the development of brain metastases due to breast cancer. Using this approach, we have identified three subsets of metastatic disease: permeable metastases, nonpermeable metastases, and solitary, dormant cancer cells, which likely have very different biology and responses to therapy. The ability to simultaneously monitor the spatial and temporal distribution of dormant cancer cells, metastatic growth, and associated tumor permeability can provide great insight into factors that contribute to malignant proliferation. Our preclinical findings suggest that standard clinical detection strategies may underestimate the true metastatic burden of breast cancer that has metastasized to the brain. A better understanding of true metastatic burden in brains will be important to assist in the development of more effective chemotherapeutics—particularly those targeted to cross the BBB—as well as detection of small nonpermeable metastases.  相似文献

The purpose of this prospective study was to determine whether using magnetic resonance imaging (MRI) for early screening for brain metastases (BM) can improve quality of life, survival in patients with non-small cell lung cancer (NSCLC). The study group comprised 183 patients newly diagnosed with NSCLC. All patients underwent limited brain MRI and routine workups. The control group comprised 131 patients with NSCLC who underwent limited brain MRI only if they had neurologic symptoms. The incidence of BM was 20.8% (38/183) in the study group and 4.6% (6/131) in the control group. The rate of upstaging based on the MRI data was 13.5% (15/111) overall and 15.9% (11/69) in patients that had been considered initially to be resectable surgically. There was no significant difference in survival outcome between the groups. Patients who had BM alone had a greater overall survival time (49 weeks) than those who had multiple systemic metastases (27 weeks; p=0.0307). In conclusions, limited brain MRI appears to be a useful, cost-effective method to screen for BM at the time of initial staging. And it may facilitate timely treatment of patients with NSCLC and improve their survival and quality of life.  相似文献

The causative mechanisms of lung cancers producing salivary-type amylase (S-Amy) were hypothesized from clinical and pathological analysis of lung cancers. A total of 260 Japanese patients who received lung lobectomy or segmentectomy during the last 4 years at Hamamatsu University Hospital, Japan, were objective patients in this study. Among the 260 patients, 212 patients were operated on for lung cancers. Of the 212 patients, 132 (62%) had adenocarcinoma and 38 (18%) had squamous cell carcinoma (SCC), of which 32 adenocarcinoma, and 8 SCC patients had metastatic lung cancers. Twenty-five (78%) of the 32 adenocarcinoma patients showed metastatic cancers from colon cancers to the lungs, especially from rectal and sigmoid colon cancers. Twenty-one (21%) of 100 primary adenocarcinoma patients and 8 (27%) of 30 primary SCC patients had double cancers coexisting with the lung cancers during the last 7 years. Among the 29 patients of double cancers, 4 lung cancer patients showed coexisting gastric cancers. The mortality rate of 79 adenocarcinoma and 22 SCC patients with primary lung cancer but not double cancer was 14% during the 4 years of this study. In 12 (12%) patients of the 101 patients with primary lung cancers, bone metastases were confirmed by bone scintigraphy. All the nine (9%) patients with brain metastases were adenocarcinoma, which was confirmed by brain magnetic resonance imaging (MRI). Serum amylase levels of the 79 adenocarcinoma and 22 SCC patients were 232 ± 343 (SD) and 156 ± 161 (SD) (IU/l), respectively, 1 day post-operation. Diabetes mellitus (DM) or borderline DM were found in 34 (43%) of the 79 adenocarcinoma and 16 (73%) of the 22 SCC patients. Of the 14 patients who died of lung cancers, 11 (79%) had DM. From these clinical and pathological findings, more than 70% of Japanese lung cancers were hypothesized to have developed from the oncogene of a retrovirus inserted into the 5' promoter of S-Amy genes (AMY1) in 60–70 age groups.  相似文献

目的探讨CA19-9、增强MRI和PET/CT在胰腺癌诊断及分期中的价值。方法回顾性分析沈阳军区总医院普外科2013年1月至2014年1月间收治的92例手术治疗的胰腺占位患者资料。患者术前均行CA19-9检查、腹部增强MRI扫描及全身PET/CT扫描,以术后病理或临床综合评价诊断为标准,比较CA19-9、增强MRI和PET/CT在胰腺癌诊断及分期中的价值。结果 92例患者中,确诊胰腺癌82例,非胰腺癌10例。CA19-9检查、腹部增强MRI及全身PET/CT对胰腺癌诊断的灵敏度分别为78.0%、86.6%和92.7%。PET/CT具有较高灵敏度,显著优于CA19-9,差异有统计学意义(P=0.008);PET/CT优于增强MRI,差异无统计学意义(P=0.200);在胰周淋巴结转移判断方面,增强MRI和PET/CT的灵敏度分别为46.9%、81.6%,二者差异有统计学意义(P〈0.001);在肝转移判断方面,增强MRI和PET/CT诊断的灵敏度分别为54.5%、72.7%,二者差异无统计学意义(P=0.66)。结论PET/CT对胰腺癌诊断有较高灵敏度,优于CA19-9、增强MRI;PET/CT有助于发现淋巴结和远处器官转移病灶,获得更加准确的术前分期,从而避免诊断性剖腹探查手术。由于仍然存在假阴性、假阳性,应该综合其他检查方法对疾病作全面分析来提高临床诊断准确性。  相似文献

INTRODUCTION: Bone metastases may change the primary treatment modality, especially if the bone is the only site of metastasis in patients considered to be in the early stage of lung cancer. It is usually diagnosed by imaging techniques. However, the diagnostic yields of imaging methods are limited. Some bone markers such as propeptides of type-1 collagen, pyridinoline cross-links and deoxypyridinoline (D-PYD) cross-links, serum osteocalcin, alkaline phosphatase are thought to be useful in the detection of bone metastasis in lung cancer. Thus, we aimed to determine the clinical usefulness of bone turnover markers in the assessment of bone metastases in patients with lung cancer. MATERIAL AND METHODS: Urinary D-PYD, calcium, and serum osteocalcin, calcium and total alkaline phosphatase (T-ALP) were measured in 60 lung cancer patients. Patients were evaluated by technetium 99 (99Tc) bone scintigraphy. The comparisons of measured values in patients with and without bone metastasis were done by using appropriate statistical methods. RESULTS: Fifty-four males and six females were included into study. Twenty-two patients had bone metastases, while 38 did not. Forty-two patients were nonsmall-cell lung cancer, whereas 18 were small-cell carcinoma. Urinary D-PYD level was the unique value that was statistically significantly higher in patients with bone metastases than that level in patients without bone metastasis (p < 0.05). CONCLUSION: Our study suggests that urinary measurement of D-PYD might be helpful in detecting bone metastasis in lung cancer. The high urinary D-PYD level may be an early sign of occult metastases in patients with no bone metastasis assessed by scintigraphic techniques.  相似文献
