干扰素调节因子7首次在EB病毒感染环境中克隆,是诱导Ⅰ型干扰素产生的关键调节因子.异常表达Ⅰ型干扰素与多种疾病有关,如肿瘤和自身免疫性疾病等.越来越多的证据表明,干扰素调节因子7是具有多种功能的转录因子,不仅调节机体的炎症、免疫反应,而且参与调节肿瘤的形成、细胞侵袭等多种生物功能.为此,本文结合最新进展对干扰素调节因子7和肿瘤的关系进行综述.  相似文献

目的探讨体重指数与恶性肿瘤之间的关系。方法选取恶性肿瘤患者180名和健康对照者120名作为调查组和对照组,对调查组患者的体重指数(BodyMassIndex,BMI)和对照组进行比较分析。结果入组者为我院确诊为恶性肿瘤患者180例,其中包括:乳腺癌33例、肺癌30例、食管鳞癌25例、肝癌20例、前列腺癌17例、子宫内膜癌17例、直肠癌15例、结肠癌14例、贲门癌9例,他们的BMI分别为(25.46±4.61)kg/m2、(22.21±3.18)kg/m2、(22.34±3.45)kg/m2、(23.43±3.14)kg/m2、(23.44±3.31)kg/m2、(25.37±4.36)kg/m2、(25.82±4.72)kg/m2、(25.93±4.81)kg/m2、(25.68±4.23)kg/m2,对照组为120例体检者(其中男性66例,女性54例),平均BMI为(23.06±3.21)kg/m2。乳腺癌、贲门癌、子宫内膜癌、直肠癌、结肠癌患者BMI与健康对照组比较差异有统计学意义(P〈0.05),肺癌、食管鳞癌、前列腺癌、肝癌患者BMI与健康对照组差异无统计学意义(P〉0.05)。结论 BMI与多种恶性肿瘤具有密切关系,建议控制BMI,减少恶性肿瘤的发生。  相似文献

Purpose

To analyze trends in second primary cancer (SPC) incidence by using a case-mix approach to standardize on first cancer site distribution.

Methods

Cases registered by 13 French cancer registries between 1989 and 2010 and followed-up until June 2013 were included. The person-year approach was used to compute standardized incidence ratios (SIRs) of metachronous SPC. Usual SIRs and cancer site–specific weighted SIRs called “case-mix SIRs” (cmSIRs) were estimated by sex and calendar period of first cancer diagnosis. Calendar trends in SIRs and cmSIRs were compared.

Results

More than 2.9 million person-years at risk were included. Among males, SIRs dropped from 1.49 to 1.23 between 1989–1994 and 2005–2010, while cmSIRs decreased from 1.40 to 1.27. This difference seems mainly related to a stronger representation of prostate cancers (at lower risk of SPC) and a weaker contribution of bladder and head and neck cancers (at higher risk of SPC) in recent periods of diagnosis. Among females, both SIRs and cmSIRs have remained stable at around 1.22 and 1.21, respectively.

Conclusions

The cmSIR is an indicator that is not influenced by changes in first cancer site distribution. Its use should be encouraged to assess second cancer incidence control.  相似文献

The definition of nodal and/or mucosal target volumes for radiation therapy for lymphadenopathies of unknown primary is controversial. Target volumes may include all nodal areas bilaterraly and be pan-mucosal or unilateral, selective, including the sole oropharyngeal mucosa. This review presents current recommendations in light of changes in the TNM classification, Human papillomavirus status and therapeutic advances. We conducted a systematic review of the literature with the following keywords: lymphadenopathy; head and neck; unknown primary and radiation therapy. There are no direct comparative studies between unilateral or bilateral nodal irradiation or pan-mucosal and selective mucosal irradiation. Contralateral lymph node failure rates range from 0 to 6% after unilateral nodal irradiation and 0 and 31% after bilateral irradiation. Occurrence of a mucosal primary varies between 0 and 19.2%. Initial clinical presentation and Human papillomavirus status are critical to define mucosal target volumes. Intensity-modulated radiotherapy is recommended (rather than three-dimensional irradiation) to avoid toxicities. Systemic treatments have similar indications as for identified primary head and neck cancers. Failures do not appear superior in case of unilateral nodal irradiation but comparative studies are warranted due to major biases hampering direct comparisons. Human papillomavirus status should be incorporated into the therapeutic strategy and practice-changing TNM staging changes will need to be evaluated.  相似文献

Background

Whether the intake of eicosapentaenoic acid (EPA) or arachidonic acid (AA) affects the risk of cancer remains unclear, and the association between the serum EPA:AA ratio and cancer risk has not been fully evaluated in general populations.

Methods

A total of 3098 community-dwelling subjects aged ≥40 years were followed up for 9.6 years (2002–2012). The levels of the serum EPA:AA ratio were categorized into quartiles (<0.29, 0.29–0.41, 0.42–0.60, and >0.60). The risk estimates were computed using a Cox proportional hazards model. The same analyses were conducted for the serum docosahexaenoic acid to arachidonic acid (DHA:AA) ratio and individual fatty acid concentrations.

Results

During the follow-up period, 121 subjects died of cancer. Age- and sex-adjusted cancer mortality increased with lower serum EPA:AA ratio levels (P trend<0.05). In the multivariable-adjusted analysis, the subjects in the first quartile of the serum EPA:AA ratio had a 1.93-fold (95% confidence interval, 1.15–3.22) greater risk of cancer death than those in the fourth quartile. Lower serum EPA concentrations were marginally associated with higher cancer mortality (P trend<0.11), but the serum DHA or AA concentrations and the serum DHA:AA ratio were not (all P trend>0.37). With regard to site-specific cancers, lower serum EPA:AA ratio was associated with a higher risk of death from liver cancer. However, no such associations were detected for deaths from other cancers.

Conclusions

These findings suggest that decreased level of the serum EPA:AA ratio is a significant risk factor for cancer death in the general Japanese population.  相似文献
