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.

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.
