Resumen

BLANCO DIEZ, A. et al. Early biochemical failure after radical prostatectomy for prostate cancer: Impact factors? Does delay from bipsy to surgery have any influence?. Actas Urol Esp [online]. 2008, vol.32, n.4, pp.406-410. ISSN 0210-4806.

Objectives: To determine wether WT may impact on the EBF (before one year) alter RRP in our series, and to study other factors that may impact on this issue. Material and methods: We study 310 RRP. Inclusion criteria are: one year follow up, no hormonal manipulation neither previous radiotherapy. Patients are divide in two groups attending WT. Group A < 90 days (n: 148), Group B > 90 days (n: 162). We study EBF (2 or more PSA determinations >= 0.2 ng/ml), and the impact of previous PSA, biopsy Gleason, Gleason of the specimen (G), pT stage (pT), and WT. T of Student or W of Wilcoxon are used to determine the homogeneity of the two groups. Chi Square of Pearson to compare the two groups EBF and pT attending to WT and EBF attending to pT. U of Mann Whitney is used to study EBF attending to G. Multivariate logistic regresion (LR) is used to study the impact of the variables on EBF. Results: There are no differences between the two groups in age (p< 0.129), PSA (p< 0.479), biopsy´s Gleason (p<0.913). There are no differences in EBF nor in pT attending to WT. Significant statystical differences are founded in EBF attending to pT and G. T3 tumors have more chance of recurrence than T2. EBF is more frecuent as G increases. In logistic regresion of the global serie, independent variables for progression are: Previous PSA and pT. Nor biopsy´s Gleason nor specimen´s Gleason, nor WT, impact on the EBF Conclusions: Biopsy Gleason and WT do not impact on EBF. WT do not impact on pT. In our serie differences on EBF are lead by previous PSA and pT. Also Gleason of the especimen seems to impact on EBF, but in lower proportion, with no significance in multivariate analysis.
