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.

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.

Purpose To assess the predictive ability of prostate-specific antigen (PSA) velocity (PSAV) and doubling time (PSADT) for biopsy progression and adverse pathology at prostatectomy among men with low-risk prostate cancer enrolled on an active-surveillance program. Methods We evaluated 290 men who met criteria for active surveillance (ie, PSA density < 0.15 ng/mL/cm3 and Gleason score ≤ 6 with no pattern ≥ 4, involving ≤ 2 cores with cancer, and ≤ 50% involvement of any core by cancer) with two or more serial PSA measurements after diagnosis from 1994 to 2008. Follow-up included twice-yearly digital rectal exam and PSA measurements and yearly surveillance biopsy. Treatment was recommended for biopsy progression (ie, Gleason score ≥ 7, or > 2 positive cores, or > 50% core involvement). Sensitivity and specificity of postdiagnostic PSAV and PSADT were explored by using receiver operating characteristic (ROC) analysis. Results Overall, 188 (65%) men remained on active surveillance, and 102 (35%) developed biopsy progression at a median follow-up of 2.9 years. PSADT was not significantly associated with subsequent adverse biopsy findings (P = .83), and PSAV was marginally significant (P = .06). No PSAV or PSADT cut point had both high sensitivity and specificity (area under the curve, 0.61 and 0.59, respectively) for biopsy progression. In those who eventually underwent radical prostatectomy, PSAV (P = .79) and PSADT (P = .87) were not associated with the presence of unfavorable surgical pathology. Conclusion Postdiagnostic PSA kinetics do not reliably predict adverse pathology and should not be used to replace annual surveillance biopsy for monitoring men on active surveillance.

Abstract Background: Many patients undergo unwanted prostate biopsy due to unreliability of prostate-specific antigen (PSA). PSA density (PSAD), free PSA, free-to-total PSA ratio, prebiopsy MRI are used to diagnose prostate cancer (PCa). Since 1863, correlations between inflammation and cancer have been identified and explored; thus, the role of various blood parameters in detecting cancer has been studied, especially neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Here, we evaluated whether these parameters before prostate biopsy can diagnose prostate cancer in our hospital.Methods: We conducted a retrospective study from January 2014 to January 2018. Prostate cancer patients were divided into significant cancer (Gleason Score ≥ 7) and insignificant cancer (Gleason Score < 7). NLR, PLR, and other clinical parameters were taken before the prostate biopsy. We then analyzed the associations of NLR and PLR alone or with PSA, with significant prostate cancer. Results: We included 463 patients, of whom 60.3% (279) had prostate cancer and 75.6 % (211) had a Gleason score (GS) of ≥ 7. PSA and PSAD in the clinically significant prostate cancer patient group were around two times more than those in the insignificant prostate cancer group. PV, NLR, PLR, and combined markers were more in the GS ≥ 7 population group. PSA combined with PLR (PPLR) and PSA with NLR (PNLR) had better area under a curve (AUC) (0.732 and 0.730, resp.), with statistical significance, than PSA, NLR, and PLR alone (0.723, 0.585, and 0.590). In the multivariate analysis using separate models with PSA and NLR or PLR compared to age, DRE-positive lesions, PV, PSAD; PNLR, and PPLR were statistically significant in finding aggressive prostate cancer. When combined markers were used together, despite the high correlations, PSA and NLR were nearly significant (p = 0.062) in detecting the GS ≥ 7 population.Conclusion: The combined use of PSA with PLR and PSA with NLR helps detect the differences between clinically significant and insignificant prostate cancer.

Purpose We evaluated whether men at risk for significant versus clinically insignificant prostate-specific antigen (PSA) failure after radical prostatectomy could be identified using information available at diagnosis. Patients and Methods A prospective prostate cancer screening study that enrolled, diagnosed, and treated 1,011 men with radical prostatectomy at Barnes-Jewish Hospital (St Louis, MO) from January 1, 1989, to June 1, 2002, for localized prostate cancer formed the study cohort. Preoperative predictors of a postoperative PSA doubling time (DT) of less than 3 months and more than 12 months or no PSA failure were identified using logistic regression. Results A preoperative PSA velocity more than 2.0 ng/mL/yr (P = .001) and biopsy Gleason score 7 (P = .006) or 8 to 10 (P = .003) were significantly associated with having a postoperative PSA DT less than 3 months. A PSA level less than 10 ng/mL (P = .005), a nonpalpable cancer (P = .001) with a Gleason score ≤ 6 (P = .0002), and a preoperative PSA increase that did not exceed 0.5 ng/mL/yr (P = .03) were significantly associated with a postoperative PSA DT of at least 12 months or no PSA failure. Most men with these preoperative characteristics and a postoperative PSA DT of 12 months or more had a persistent postoperative PSA level of at least 0.2 ng/mL that did not exceed 0.25 ng/mL after a median follow-up of 3.6 years. Conclusion A postoperative PSA DT less than 3 months is associated with a preoperative PSA velocity more than 2.0 ng/mL/yr and high-grade disease. Select men with a postoperative PSA DT more than 12 months may not require salvage radiation therapy.
