Pulmonary Carcinosarcoma: A Surveillance,Epidemiology, and End Results (SEER) Analysis

IntroductionPulmonary carcinosarcoma (PC) is a rare malignant neoplasm composed of epithelial and mesenchymal components. It accounts for < 1% of thoracic cancers and is not fully understood. This study examined Surveillance, Epidemiology, and End Results (SEER) data to describe demographic and clinical characteristics of patients with PC and assessed survival outcomes by treatment modality and stage.Patients and MethodsSEER data were reviewed to identify patients diagnosed with primary PC (1973-2012). Overall survival (OS) and disease-specific survival (DSS) were analyzed by univariate/multivariable Cox proportional hazards models and Kaplan-Meier methods.ResultsA total of 411 patients were included. Median age was 67 (range, 24-96) years. Disease stage at the time of initial diagnosis was known for 74.7% of the identified patients (307/411). Of these patients, 23.1% had localized disease. Survival was significantly better for patients with localized disease (OS: 31 vs. 6 months, P < .001; DSS: 54 vs. 8 months, P < .001). Additionally, patients who received surgery alone had significantly improved OS (20 months; P < .001) and DSS (32 months; P < .001) compared to patients who received combined surgery and radiotherapy (OS: 7 months; DSS: 8 months) or radiotherapy alone (OS: 4 months; DSS: 4 months).ConclusionTreatment with surgery alone resulted in superior survival outcomes compared to other treatment modality combinations, regardless of patient age and disease stage. Within the limitations of this study, providers may wish to consider these findings when devising patient treatment plans.     

Clinicopathological characteristics and perineural invasion in adenoid cystic carcinoma: a systematic review

IntroductionAdenoid cystic carcinoma is the most frequent malignant tumor of the submandibular gland and the minor salivary glands. It is a malignant neoplasm that, despite its slow growth, shows an unfavorable prognosis.ObjectivesThe aim of this study was to perform a systematic review of the literature on Adenoid cystic carcinoma in the head and neck region and its clinicopathological characteristics, with emphasis on the perineural invasion capacity of the tumor.MethodsA systematic search of articles published between January 2000 and January 2014 was performed in the PubMed/MEDLINE, SciELO, Science Direct, and Scopus databases.ResultsNine articles were selected for this systematic review. These demonstrated that the female gender was more often affected and that malignant tumors showed a high rate of distant metastasis, recurrence, and a low survival rate. The presence of perineural invasion ranged from 29.4% to 62.5% and was associated with local tumor recurrence.ConclusionAdenoid cystic carcinoma is commonly characterized by the presence of pain, high rate of recurrence, metastasis, and a low survival rate. Reporting studies with patient follow-up is of utmost importance for a better clinical-pathological understanding and to improve the prognosis of this pathology.

ELAM-1在鼻咽癌裸鼠移植瘤中的表达及其与转移的关系

目的 建立裸鼠鼻咽癌转移模型并探讨 E-选择素（ELAM-1）与鼻咽癌转移的相关性。方法 将鼻咽癌5-8F细胞悬液注射于裸鼠左后肢爪垫，观察裸鼠状态、成瘤情况并测量裸鼠体重及移植瘤长短径；采用连续病理切片苏木精-伊红染色观察移植瘤及转移情况，将16只人鼻咽癌荷瘤裸鼠分为转移组和非转移组；采用免疫组织化学法检测两组移植瘤组织中ELAM-1的表达。 结果 16只裸鼠均成瘤，成瘤率为100.0%，其中10只裸鼠出现转移瘤，转移率为62.5%。建模前，两组裸鼠体重差异无统计学意义［（13.83±0.56）g vs （14.62±0.30） g，t=1.026，P=0.071］。建模后4~7周，裸鼠瘤体体积呈指数增长，且转移组移植瘤增长速度较非转移组快，非转移组裸鼠瘤体体积小于转移组［（198.91 ± 163.29） mm³ vs （268.76 ±174.31） mm³，t=4.376，P=0.005］。ELAM-1在鼻咽癌裸鼠移植瘤、淋巴结转移灶及远处转移灶中的表达均为阳性，主要表达于细胞膜。转移组移植瘤光密度值高于非转移组（0.4497±0.0705 vs 0.0435±0.0082，t=4.388，P＝0.001）。结论 本研究成功构建稳定性好、转移率高的鼻咽癌裸鼠移植瘤转移模型，且ELAM-1在裸鼠移植瘤中高表达，可促进鼻咽癌裸鼠移植瘤生长和转移。     

Long-term health-related quality of life of breast cancer survivors remains impaired compared to the age-matched general population especially in young women. Results from the prospective controlled BREX exercise study

ObjectiveTo investigate long-term health-related quality of life (HRQoL) changes over time in younger compared to older disease-free breast cancer survivors who participated in a prospective randomized exercise trial.MethodsSurvivors (aged 35–68 years) were randomized to a 12-month exercise trial after adjuvant treatment and followed up for ten years. HRQoL was assessed with the generic 15D instrument during follow-up and the younger (baseline age ≤ 50) and older (age >50) survivors’ HRQoL was compared to that of the age-matched general female population (n = 892). The analysis included 342 survivors.ResultsThe decline of HRQoL compared to the population was steeper and recovery slower in the younger survivors (p for interaction < 0.001). The impairment was also larger among the younger survivors (p = 0.027) whose mean HRQoL deteriorated for three years after treatment and started to slowly improve thereafter but still remained below the population level after ten years (difference −0.017, 95% CI: −0.031 to −0.004). The older survivors’ mean HRQoL gradually approached the population level during the first five years but also remained below it at ten years (difference −0.019, 95% CI: −0.031 to −0.007). The largest differences were on the dimensions of sleeping and sexual activity, on which both age groups remained below the population level throughout the follow-up.ConclusionsHRQoL developed differently in younger and older survivors both regarding the most affected dimensions of HRQoL and the timing of the changes during follow-up. HRQoL of both age groups remained below the population level even ten years after treatment.

目的探讨心脏非黏液性肿瘤临床特点,总结外科治疗经验。方法对我院1996年10月至2005年3月进行外科治疗的56例心脏非黏液性肿瘤的临床资料进行回顾性分析,总结其临床表现、发生部位、肿瘤性质和外科治疗特点等。结果心脏非粘液性肿瘤占本院同期手术患者的0.14%,良性肿瘤28例,恶性肿瘤28例,其中继发性心脏肿瘤8例。良性肿瘤最常见的是生长在心室,共18例;恶性肿瘤最常见的生长部位是心房,共15例。外科治疗行急诊手术者12例。心包开窗引流术2例,探查术1例,术中肿瘤全部切除者26例,部分切除27例,术后住院期间死亡1例。结论心脏非黏液性肿瘤临床表现各异、病理类型多样、病变广泛,手术原则为尽可能切除肿瘤和保持心脏结构的完整性和功能。     

肺癌胸膜早期种植转移:螺旋CT与手术病理对照研究

目的:评价CT诊断肺癌胸膜早期种植转移的价值,并分析漏诊原因。方法:回顾性分析43例经手术病理确诊肺癌胸膜种植转移的CT、手术病理资料,作对照研究。结果:43例中,术前CT仅诊断8例,其中Ⅲ级5例,Ⅱ级3例,诊断符合率19%(8/43),CT实际显示胸膜转移结节28例,其中Ⅰ级10例、Ⅱ级13例,Ⅲ级5例,未显示Ⅰ级15例,CT检出率为65%(28/43)。28例中,术前CT漏诊Ⅰ级和Ⅱ级各10例,漏诊率71%(20/28)。20例中,CT漏诊叶间胸膜、肺表面脏层胸膜、纵隔胸膜、肋胸膜、膈胸膜转移,漏诊率分别为0%、33%、36%、43%、80%。结论:CT能准确检出、诊断肺癌中晚期胸膜转移,但检出胸膜早期微小病灶有明显局限性,在CT诊断中,忽视对膈胸膜、肋胸膜、肺表面脏胸膜上Ⅰ、Ⅱ级较早转移灶的观察,是导致漏诊的原因之一。

Ets-1、MMP-1及TIMP-1在膀胱移行细胞癌中的表达

目的研究Ets-1、基质金属蛋白酶1(MMP-1)及基质金属蛋白酶1抑制物(TIMP-1)在膀胱移行细胞癌(BTCC)中的表达及意义。方法用免疫组化方法检测40例BTCC组织和12例正常膀胱黏膜组织中Ets-1、MMP-1及TIMP-1的表达;分析Ets-1与BTCC临床病理特征间的关系;研究BTCC中MMP-1、TIMP-1表达与Ets-1表达的相关性。结果①Ets-1在BTCC中高度表达,阳性率为82.5%(P<0.01),且随BTCC临床分期和病理分级的升高而增加,肿瘤复发组高于无复发组,肿瘤转移组高于无转移组(P<0.05)。②MMP-1阳性表达率膀胱癌组(85.0%)明显高于对照组(58.3%)(p<0.05);TIMP-1阳性表达率对照组(83.3%)明显高于膀胱癌组(47.5%)(P<0.05)。③MMP-1与Ets-1表达呈正相关(Rs为0.824,P<0.01),而TIMP-1与Ets-1表达呈负相关(Rs为-0.821,P<0.01)。结论①Ets-1在BTCC中高度表达,并随BTCC分期分级升高而增加;Ets-1与BTCC转移及复发密切相关。②BTCC中Ets-1上调MMP-1表达,而下调TIMP-1表达,从而参与BTCC侵袭与转移。
