Expression and prognostic influence of MMP-2, MMP-9 and TIMP-2 in non-small cell lung cancer

Background Matrix metalloproteinases (MMPs) are a family of endopeptidases that digest the extracellular matrix (ECM). Overexpression of different MMPs has been shown to promote tumour cell invasion in vitro. Tissue inhibitors of matrix metalloproteinases (TIMPs) are specific inhibitors of MMPs that also possess growth-promoting properties. Aims To analyse the expression profile of MMP-2, MMP-9 and TIMP-2 in non-small cell lung cancer (NSCLC) and to assess the impact of expression on survival. Methods This is a retrospective study of patients who underwent resection for stage I-IIIa NSCLC with a post-operative survival >60 days. Patient follow up was a minimum of 2 years. Standard ABC immunohistochemistry was performed on 4μm paraffin-embedded sections from the tumour periphery using monoclonal antibodies to MMP-2, MMP-9 and TIMP-2. Results The results of the immunohistochemistry are set out below. marker tumour expression log-rank survival stromal expression log-rank survival MMP-2 9/72 (13%) p=0.10 34/72 (47%) p=0.34 MMP-9 79/152 (52%) p=0.04* 69/152 (45%) p=0.84 TIMP-2 28/90 (31%) p=0.04* 66/90 (73%) p=0.90 Two or more 16/59 (27%) p=0.007* There were no associations between expression and clinicopathological findings for any tumour marker. There was co-expression of MMP-2 and MMP-9 in tumour cells (p=0.01). Conclusions MMP-2, MMP-9 and TIMP-2 are expressed in NSCLC. MMP-9 and TIMP-2 tumour expression correlate with a poor outcome (both p=0.04) and are potential prognostic markers for NSCLC. Cumulative expression of two or more MMPs/TIMPs may also have increased prognostic significance. Proteases and their inhibitors are novel targets for therapeutic intervention and should be evaluated in NSCLC.

Risk factors (excluding hormone therapy) for endometrial hyperplasia: a systematic review.

Objective: To conduct a systematic review of risk factors associated with the development of Endometrial Hyperplasia (EH).

Data sources: Ovid MEDLINE, EMBASE and Web of Science databases were searched from inception to 30 June 2015.

Study eligibility: Fifteen observational studies that reported on EH risk in relation to lifestyle factors (n=14), medical history (n=11), reproductive and menstrual history (n=9) and measures of socio-economic status (n=2) were identified. Pooled relative risk estimates and corresponding 95% confidence intervals (CI) were able to be derived for EH and Body Mass Index (BMI), smoking, diabetes and hypertension, using random effects models comparing high versus low categories.

Results: The pooled relative risk for EH when comparing women with the highest versus lowest BMI was 1.82 (95% CI 1.22–2.71; n=7 studies, I2=90.4%). No significant associations were observed for EH risk for smokers compared with non-smokers (RR 0.88, 95% CI 0.66-1.17; n=3, I2=0.0%), hypertensive versus normotensive women (RR 1.51, 95% CI 0.72–3.15; n=5 studies, I2=79.1%), or diabetic versus non-diabetic women (RR 1.77, 95% CI 0.79–3.96; n=5 studies, I2=31.8%) respectively although the number of included studies was limited. There were mixed reports on the relationship between age and risk of EH. Too few studies reported on other factors to reach any conclusions in relation to EH risk.

Conclusions: A high BMI was associated with an increased risk of EH, providing additional rationale for women to maintain a normal body weight. No significant associations were detected for other factors and EH risk, however relatively few studies have been conducted and few of the available studies adequately adjusted for relevant confounders. Therefore, further aetiological studies of endometrial hyperplasia are warranted.

Law and narrative: a life history interview with a Brazilian jurist

This article discusses some issues in communicating experience, based on a life history interview with 83-year-old Brazilian jurist Evandro Lins e Silva conducted by the Getúlio Vargas Foundation’s oral history program (Centro de Pesquisa e Documentação de História Contemporânea do Brasil, or CPDOC) between August 1994 and January 1995.1The text focuses especially on two images used by the interviewee, which consolidate both the experiences that have been communicated to him and the experience that he himself endeavors to communicate regarding his activities as an attorney and the status of truth within the field of law.
