Abstract

Metalloproteases (MMPs) and tissue inhibitor of metalloprotease-3 (TIMP-3) have been associated to the risk of having cancer and tumor aggressiveness. When facing the difficulties of prostate cancer diagnosis, the expression of MMPs and TIMP-3 in negative biopsies could be helpful to evaluate a diagnostic suspicion. Our objective is to carry out a comparative study of the expression of MMPs and TIMP-3 in previous negative biopsies and radical prostatectomies (RP).

Material and methods

Retrospective analysis of a hospital-based cohort including 21 patients with suspicion of prostate carcinoma, whose expressions of MMP-2, 9, 11 and 13 and TIMP-3 were evaluated by immunohistochemistry in the tumor area from previous negative biopsies and RP.

Results

Immunohistochemical staining values (Score) for MMPs (-11 and -13) and TIMP-3 showed no significant differences when comparing the areas of negative biopsies where tumors subsequently developed with those of the RP. However, we did observe a significant difference in the increased expression of MMP-2 (P=0.002) and MMP-9 (P=0.001) in the tumor area of the RP with respect to the corresponding area of the previous negative biopsy.

Conclusions

Our data indicate a higher overall expression of MMP-2 and MMP-9 in the tumor area of the RP compared to the corresponding areas of the negative previous biopsy, which seems to be associated to the process of malignant transformation.

Resumen

Las metaloproteasas (MMPs) y el inhibidor tisular de metaloproteasas-3 (TIMP-3) se han relacionado con el riesgo de padecer cáncer y con la agresividad de varios tumores. En ocasiones, existen muchas dificultades para diagnosticar el cáncer de próstata (CaP), la expresión de MMPs y del TIMP-3 en biopsias negativas nos podría ayudar a realizar una sospecha diagnóstica en estos casos. El objetivo es realizar un estudio comparativo de la expresión de MMPs y TIMP-3 en las biopsias previas negativas y las prostatectomías radicales (PR).

Material y métodos

Análisis retrospectivo de una cohorte de base hospitalaria que incluye 21 pacientes con sospecha de carcinoma prostático en los que se analizaron por técnica inmunohistoquímica las expresiones de MMP-2, 9, 11 y 13 y el TIMP-3 en la zona tumoral, tanto de las biopsias previas negativas como de las PR.

Resultados

Los valores de tinción inmunohistoquímicos Score para las MMPs -11 y -13 y TIMP-3 no mostraron diferencias significativas al comparar las áreas de las biopsias negativas donde luego se desarrolló tumor con las de la PR. Sin embargo, si que observamos una diferencia significativa aumentando la expresión de la MMP-2 p=0,002 y MMP-9 p=0,001 en la zona tumoral de la PR con respecto al área correspondiente de la biopsia previa negativa.

Conclusiones

Nuestros datos indican una mayor expresión global de la MMP-2 y MMP-9 en la zona tumoral de la PR en comparación con las áreas correspondientes de la biopsia previa negativa, lo que parece estar en relación con el proceso de transformación maligna.
