Objectives: We used a new GP score (Gleason score multiplied by prostate-specific antigen) without the T stage as a predictive value for biochemical failure (BCF) after prostatectomy. Materials and Methods: We assessed 459 prostate cancer patients who underwent prostatectomies at our institution. Three sub-groups were defined in terms of D'Amico classification risk (low, intermediate, and high) and Gleason score (low, < 50; intermediate, 50-100; and high GP score, > 100). Risk factors for BCF were evaluated by multivariate analysis with a Cox hazard model. A log-rank test was used to compare the BCF rate in the 2 groups. Results: There was nosignificant difference in the non-BCF rate between the lowrisk and low GP score subgroups or the intermediate risk andintermediate GP score subgroups. In contrast, the non-BCFrate of the high GP score subgroup (42.1%) was significantlylower than that of the high-risk subgroup (66.1%, log-rankp = 0.008). Based on multivariate analysis, a high GP score(p = 0.001; HR 3.78; 95%CI 1.95-7.35) was a significant independent risk factor for BCF after prostatectomy. Conclusion: The GP score, consisting of two absolute numbers, may be a valuable predictive factor for BCF after prostatectomy, especially in the high-risk failure group.

Ligoniai ir metodai Į tyrimą įtraukti 142 prostatos vėžiu sergantys ligoniai, kuriems buvo atliktos radikalios prostatektomijos. Ankstyvas biocheminis atkrytis konstatuotas, kai prostatos specifinio antigeno koncentracija, praėjus 3 mėn. po operacijos, buvo >0,2 ng/ml. Neoadjuvantinė terapija (hormonų ar spindulių) buvo pagrindinis atmetimo kriterijus. Vertinta prostatos specifinio antigeno koncentracija, vėžio diferenciacijos laipsnis iki ir po operacijos, vėžio stadija, prostatos chirurginio šalinimo išlaidos. Rezultatai Galutinei analizei panaudoti 94 ligonų duomenys. Vidutinis jų amžius buvo 66,6 metų, prostatos specifinis antigenas iki operacijos – 9,87 ng/ml, Gleason diferenciacijos laipsnis iki operacijos – 5,87, diferenciacijos laipsnis po operacijos – 6,38, teigiami rezekciniai kraštai rasti 36 (38%), ankstyvas biocheminis atkrytis – 13 (14%) pacientų. Atlikus logistinę regresijos analizę nustatyta, jog ankstyvą biocheminį atkrytį galima patikimai prognozuoti, kai Gleason pooperacinis vėžio diferenciacijos laipsnis didesnis nei 7 (p = 0,02, tikimybių santykis – 7,8) ir vėžio stadija T3b (p = 0,012, tikimybių santykis – 6,76). Išvados Remiantis ikioperaciniais objektyviais veiksniais negalima patikimai prognozuoti ankstyvo biocheminio atkryčio. Prostatos vėžio išplitimas į sėklines pūsleles (T3b stadija) ir Gleasono pooperacinis vėžio diferenciacijos laipsnis > 7 leidžia reikšmingai prognozuoti ankstyvą biocheminį atkryti, po radikalios prostatektomijos, tokiems ligoniams indikuojamas ankstyvas adjuvantinis gydymas, nelaukiant biocheminio atkryčio požymių. Reikšminiai žodžiai: prostatos vėžys, radikali prostatektomija, ankstyvas biocheminis atkrytis Can objective preoperative parameters predict early biochemical recurrence after radical prostatectomy?

Patients and methods The study embraced 142 patients that underwent radical retropubic prostatectomy. Early biochemical failure was defined as a prostate-specific antigen level 3 months after radical prostatectomy > 0.2 ng/ml. Neoadjuvant treatment (hormonal therapy or radiation) was the mane exclusion criteria. Preoperative antigen concentration, Gleason score at the biopsy, patients’ age, postoperative Gleason score, stage and surgical margins were investigated as possible predictors of early biochemical recurrence. Results Final analysis was done using data on 94 patients. The mean patients’ age was 66.6 years and mean preoperative prostate specific antigen concentration 9.87 (range 0.44–98.4) ng/ml. The mean Gleason score preoperatively was 5.87 (range 2–8) and postoperatively 6.38 (range 4–9). Positive surgical margins were in 36 (38%) and early biochemical failure was detected in 13 (14%) cases. Logistic regression analysis shows that postoperative Gleason score >7 (p = 0.02, OR-7.8) and stage pT3b (p = 0.012, OR-6.76) are powerful parameters for predicting early biochemical recurrence. Conclusions Preoperative parameters cannot predict early biochemical recurrence. Postoperative parameters such as Gleason score >7 and stage pT3b are useful in the prediction of early biochemical recurrence. In such patients early adjuvant treatment is advisable.

Objective: To evaluate clinical predictors of lymph node invasion (LNI) in patients with high-risk prostate cancer undergoing radical prostatectomy (RP) with extended pelvic lymph node dissection (ePLND). Methods: A contemporary cohort of 116 patients, who underwent ePLND during RP, was retrospectively evaluated. Patients were classified into 3 groups including cases without LNI (group 1), with 1 to 3 positive nodes (group 2; limited LNI), and with more than 3 positive nodes (group 3; extensive LNI). The multinomial logistic regression model (multivariate analysis) evaluated the risk of LNI. Results: Overall, 30 patients (25.9%) had LNI, which was limited in 17 cases (14.7%) and extensive in 13 subjects (11.2%). Median prostate-specific antigen (PSA) was higher in cases with limited (11.4 ng/mL) or extensive (23.5 ng/mL) LNI than cases without (7.3 ng/mL) and the difference was significant ( p <.0001). Median proportion of biopsy-positive cores was higher in limited (0.64) or extensive (0.54) LNI than cases without (0.34) and the difference was significant ( p < .0001). The distribution of other factors did not show any significant difference among the groups. On multivariate analysis, only higher values of PSA significantly affected the odds of extensive LNI when compared to cases without (odds ratio, 1.054; p = .005); PSA showed a fair discrimination power (area under the curve 0.792). Conclusion: PSA was the only independent predictor of extensive LNI and could be an important preoperative factor for stratifying high-risk patients.

ObjectivesTo determine whetherETS-related gene(ERG) expression can be used as a biomarker to predict biochemical recurrence and prostate cancer-specific death in patients with high Gleason grade prostate cancer treated with androgen deprivation therapy (ADT) as monotherapy.MethodsA multicentre retrospective cohort study identifying 149 patients treated with primary ADT for metastatic or non-metastatic prostate cancer with Gleason score 8–10 between 1999 and 2006. Patients planned for adjuvant radiotherapy at diagnosis were excluded. Age at diagnosis, ethnicity, prostate-specific antigen and Charlson-comorbidity score were recorded. Prostatic tissue acquired at biopsy or transurethral resection surgery was assessed for immunohistochemical expression ofERG. Failure of ADT defined as prostate specific antigen nadir +2. Vital status and death certification data determined using the UK National Cancer Registry. Primary outcome measures were overall survival (OS) and prostate cancer specific survival (CSS). Secondary outcome was biochemical recurrence-free survival (BRFS).ResultsThe median OS of our cohort was 60.2 months (CI 52.0 to 68.3).ERGexpression observed in 51/149 cases (34%). Multivariate Cox proportional hazards analysis showed no significant association betweenERGexpression and OS (p=0.41), CSS (p=0.92) and BRFS (p=0.31). Cox regression analysis showed Gleason score (p=0.003) and metastatic status (p<1×10-5) to be the only significant predictors of prostate CSS.ConclusionsNo significant association was found betweenERGstatus and any of our outcome measures. Despite a limited sample size, our results suggest thatERGdoes not appear to be a useful biomarker in predicting response to ADT in patients with high risk prostate cancer.

PURPOSE Prostate-specific antigen (PSA) has been used as a marker of advanced prostate cancer but remains controversial. To evaluate PSA as a predictor of survival, we analyzed data from sequential phase II trials of estramustine and etoposide. METHODS A landmark analysis that used data from 62 men with PSA levels at baseline and 8 weeks was conducted. The best PSA measure (of six evaluated) was incorporated into a multiple regression model with performance status (PS); relative change in PSA level; and pretreatment PSA, alkaline phosphatase, and hemoglobin values. RESULTS A decrease in PSA of 50% or greater at 8 weeks was associated with a significantly increased survival (P=.0005, two-sided log-rank test). Median survival from the landmark was 91 weeks in patients with a 50% or greater decrease at 8 weeks versus 38 weeks in those without this decrease. Modeling showed that PS, pretreatment hemoglobin level, and relative change in PSA level were significant prognostic factors, with a significant interaction between PS and pretreatment hemoglobin level. In the final model, a relative change in PSA level at 8 weeks of less than 50% had an adjusted relative risk of 2.20 (95% confidence interval, 1.21 to 4.00). A decrease in PSA level of 50% or greater at any time during therapy was associated with a response in measurable disease (P=.0369, two-sided Fisher's exact test). CONCLUSION The PSA value after 8 weeks of this cytotoxic regimen does predict survival. A decrease in PSA level is associated with both survival and response in soft tissue lesions and should be incorporated into the response criteria and reporting of trials of cytotoxic agents in prostate cancer.
