Abstract
INTRODUCTION We evaluated the correlation between the International Society of Urological Pathology (ISUP) grades and the aggressiveness grades of prostate inflammation in newly diagnosed prostate cancer patients with chronic asymptomatic prostatitis National Institiutes of Health (NIH) category IV (CAPNIHIV). METHODS The study comprised 357 consecutive patients with prostate cancer in whom a cancer diagnosis had been made via a prostate needle biopsy. Histological sections of the prostate biopsy specimens of the patients were reviewed and scored. Prostatic inflammation was scored using the aggressiveness grade of inflammation. The associations between the ISUP grades and the aggressiveness grades of inflammation were analyzed using logistic regression. The limitations of the study were its retrospective design and the limited number of cases. RESULTS In 110 (31%) patients, CAPNIHIV was detected: 56 (51%) patients had a grade 0 aggressiveness score, 34 (31%) patients had a grade 1 aggressiveness score, and 20 (18%) patients had a grade 2 aggressiveness score. The patients who had prostatic inflammation had 1.65 times (95% confidence interval [CI] 1.05-2.61) greater likelihood of a high ISUP grade (grade ≥3) compared with the patients who did not have prostatic inflammation. The association between the ISUP grade and the aggressiveness grade of inflammation was more pronounced for a grade 2 aggressiveness score (n= 20; odds ratio 2.97; 95% CI 1.14-7.71). CONCLUSIONS In prostate cancer patients with CAPNIHIV, there was a positive correlation between the inflammation aggressiveness grade and the ISUP grade. The aggressiveness of intraprostatic inflammation may be an important morphological factor affecting the Gleason score.

Gleason score 7 prostate cancer treated with interstitial brachytherapy with or without supplemental external beam radiation and androgen deprivation therapy: is the primary pattern on needle biopsy prognostic? Brachytherapy 2012; 12:14-8. [PMID: 22884256 DOI: 10.1016/j.brachy.2012.05.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2012] [Revised: 05/11/2012] [Accepted: 05/29/2012] [Indexed: 11/25/2022]
Abstract
PURPOSE To evaluate the effect of primary Gleason pattern on biochemical progression-free survival (bPFS), cause-specific survival (CSS), and overall survival (OS) in Gleason 7 prostate cancer patients treated with low-dose-rate (LDR) interstitial brachytherapy with or without supplemental external beam radiation therapy and androgen deprivation therapy. METHODS AND MATERIALS We retrospectively reviewed the medical records of 932 consecutive patients with biopsy-confirmed Gleason 7 prostate cancer who received LDR interstitial brachytherapy as a component of their definitive treatment regimen. Treatment outcomes were compared between patients with primary Gleason pattern 3 and 4. RESULTS With a median followup of 7.4 years, the 10- and 14-year bPFS, CSS, and OS for the entire Gleason 7 study group were 95.7/95.7%, 98.6/98.6% and 77.2/64.3%, respectively. When biochemical control was evaluated as a function of primary Gleason pattern, the primary pattern 3 had a statistically higher 10- and 14-year bPFS (97.8/97.8% vs. 93.1/93.1%, p=0.006). The Gleason pattern 3 patients also trended toward a higher 10- and 14-year CSS (99.3/99.3% vs. 96.9/96.9%, p=0.058). OS was not statistically different between the two Gleason 7 cohorts. CONCLUSIONS Gleason 7 prostate cancer patients treated with LDR interstitial brachytherapy have an excellent long-term outcome. There was a small but statistically significant advantage in bPFS and a trend toward improved CSS in patients with a primary Gleason pattern of 3.

Abstract
Prostate cancer is a leading malignancy among men. Early prostate cancer is most commonly treated with radical surgery and radiotherapy. In the era of prostate-specific antigen and newly emerging highly specific screening tests, a greater number of men are given a diagnosis earlier in life, and disease is more often confined. Less-invasive treatments, such as focal therapy, are becoming increasingly popular, yielding shorter hospital stays, faster recovery, and fewer complications. Potential drawbacks to focal therapy include the risk of incomplete treatment, which may result from missed cancer foci and inadequate ablation to target tissues. Furthermore, this approach is not universally applicable to all patients--for example, those who have periurethral and extraprostatic extension of the tumor may not benefit from focal treatment. This article reviews the importance of multifocal prostate cancer and the application of focal treatment.

Abstract
BACKGROUND The impact of primary Gleason pattern was determined on cause-specific (CSS), biochemical progression-free (bPFS), and overall survival (OS) after brachytherapy for Gleason score 7 prostate cancer. METHODS From April 1995 to October 2003, 530 patients underwent brachytherapy for Gleason score 3+4 (n = 300) or Gleason 4+3 (n = 230) prostate cancer. All patients underwent brachytherapy more than 3 years before analysis. The median follow-up was 5.7 years. Of the 530 patients, 412 (77.7%) received supplemental external beam radiation therapy (XRT) and 177 (33.4%) received androgen deprivation therapy. bPFS was defined by a prostate-specific antigen (PSA) </=0.40 ng/mL after nadir. Multiple parameters were evaluated as predictors of CSS, bPFS, and OS. RESULTS At 10 years, Gleason 3+4 versus 4+3 did not predict for CSS (96.7% vs 93.3%, P = .506), bPFS (97.0% vs 92.9%, P = .085), or OS (77.0% vs 78.0%, P = .933). Cox linear regression analysis demonstrated that clinical stage and radiation dose (D90) predicted for CSS, whereas pretreatment PSA, clinical stage, and prostate size predicted for bPFS. Patient age, diabetes, and tobacco were the strongest predictors for OS. To date, 57 patients have died, with 80.7% due to cardiovascular/pulmonary events or secondary malignancies. Five patients have died of prostate cancer. CONCLUSIONS The primary Gleason pattern did not impact CSS, bPFS, or OS in Gleason score 7 prostate cancer. Deaths from cardiovascular/pulmonary disease and second malignancies were 9.6 times more common than death from prostate cancer.

Abstract
BACKGROUND The aim of this study was to review the discrepancies in Gleason scores (GS) of prostate biopsies and radical prostatectomy specimens and the effects of multiple-needle biopsies on scoring accuracy. METHODS One hundred patients who had undergone consecutive radical prostatectomies (RP) between January 2004 and May 2006 were reviewed retrospectively. Patient information including age, prebiopsy prostate-specific antigen levels, biopsy GS, RP GS and pathology details were recorded and compared. RESULTS The concordance rate of biopsy GS and RP GS was found to be at 43%, with 46% of biopsy specimens being undergraded. Eleven per cent of the specimens were overgraded. The accuracy was fairly similar when specimens were reported by the same or different pathologists, at 42 and 44%, respectively. The accuracy of biopsy GS improved with increasing number of biopsies taken. CONCLUSION There are significant discrepancies in Gleason scoring of biopsy and RP specimens, with a concordance rate of 43% and undergrading rate of 46%. Increasing the number of biopsies helps improve scoring accuracy. Clinicians and patients need to be mindful when deciding cancer treatment options, in view of these discrepancies.

Abstract
PURPOSE We determined the long-term clinical significance of primary Gleason pattern in patients with Gleason score 7 prostate cancer. MATERIALS AND METHODS We reviewed the records of all patients who underwent bilateral pelvic lymph node dissection and radical retropubic prostatectomy for Gleason score 7 prostate cancer at our institution. All patients who underwent adjuvant hormonal or radiation therapy were excluded from analysis. Patients were monitored for biochemical failure, that is PSA progression, systemic recurrence and cancer specific survival. RESULTS We identified 1,688 patients who met admission criteria, of whom 1,256 (74.4%) had primary Gleason pattern 3 and 432 (25.6%) had primary Gleason pattern 4. Median followup was 6.9 years. At 10 years primary Gleason pattern 3 was associated with increased biochemical recurrence-free survival (48% vs 38%, p <0.001), lower systemic recurrence (8% vs 15%, p <0.001) and higher cancer specific survival (97% vs 93%, p = 0.013) for Gleason primary grades 3 and 4, respectively. All of these end points remained significant on multivariate analysis when controlling for preoperative PSA, seminal vesicle involvement, margin status, DNA ploidy and TNM staging. PSA doubling time was shorter in patients with primary Gleason pattern 4 (1.64 vs 1.01 years). Systemic recurrence and cancer specific survival were associated with a PSA doubling time of less than 1 year. CONCLUSIONS Gleason score 7 prostate cancer is a heterogeneous entity. We should continue to stratify patients according to primary Gleason pattern. Patients with Gleason score 4 + 3 prostate cancer have more aggressive disease and experience higher rates of biochemical failure, systemic recurrence and cancer specific death.

Abstract
OBJECTIVES To examine the relationship among needle biopsy primary grade, prostatectomy grade, and postprostatectomy biochemical recurrence among men with Gleason score 7 disease. METHODS We identified 320 men with Gleason score 7 tumors on prostate biopsy treated with radical prostatectomy between 1991 and 2001 by a single surgeon. None of these patients had received neoadjuvant or adjuvant hormonal therapy or radiotherapy. The chi-square test and Kaplan-Meier method were used to evaluate the correlation among biopsy Gleason score, prostatectomy Gleason score, and biochemical recurrence. RESULTS A total of 252 (79%) and 68 (21%) men had primary Gleason pattern 3 and 4 identified on needle biopsy, respectively. Of the patients with Gleason pattern 3 + 4 tumors on biopsy, 24% were upgraded to primary pattern 4 or more on final pathologic analysis. Of the patients with Gleason pattern 4 + 3 tumors on biopsy, 47% were downgraded to primary pattern 3 or less on final pathologic analysis. The actuarial risk of biochemical prostate-specific antigen recurrence was significantly lower among patients with Gleason pattern 4 + 3 on biopsy, if the prostatectomy Gleason score was downgraded to 3 + 4 or less (P = 0.03). CONCLUSIONS Approximately 47% of men with a diagnosis of Gleason pattern 4 + 3 on needle biopsy are downgraded at radical prostatectomy and will have biochemical prostate-specific antigen recurrence-free outcomes similar to patients originally diagnosed with Gleason pattern 3 + 4 adenocarcinoma. This group of patients may benefit from definitive treatment such as radical prostatectomy for management of their disease.

Abstract
PURPOSE Although the perception exists that biochemical outcome in patients with a Gleason score of 7 with dominant pattern 4 histology is inferior to that of patients with a Gleason score of 7 with a primary Gleason grade of 3, conflicting conclusions have been reported for radical prostatectomy and brachytherapy. In this study, we evaluate the effect of the dominant histologic pattern in Gleason score 7 prostate cancer on biochemical progression-free survival after brachytherapy. MATERIAL AND METHODS Between April 1995 and October 2001, 273 consecutive patients underwent permanent interstitial brachytherapy without androgen deprivation therapy for clinical T1c-T3a NxM0 (2002 American Joint Committee on Cancer) prostate cancer. No patient underwent seminal vesicle biopsy or pathological lymph node staging. All patients underwent brachytherapy more than 3 years before analysis. Biochemical progression-free survival was defined by a prostate specific antigen (PSA) cut point < or = 0.4 ng/mL after nadir or by the American Society for Therapeutic Radiology and Oncology (ASTRO) consensus definition. The median follow-up was 4.7 years. Clinical, treatment, and dosimetric parameters evaluated for biochemical progression-free survival included primary Gleason grade; clinical T stage; pretreatment PSA level; risk group; percent positive biopsy results; perineural invasion; patient age; isotope; supplemental external-beam radiation therapy; prostate volume; brachytherapy planning volume; percent of the target volume receiving 100%, 150%, and 200% of the prescribed dose (V100/150/200); minimum percent of the prescribed dose covering 90% of the target volume (D90); tobacco consumption; hypertension; and diabetes. RESULTS For the entire cohort, the actuarial 8-year biochemical progression-free survival rate was 94.5% and 94.8% using a PSA cut point < or = 0.4 ng/mL after nadir and the ASTRO consensus definition, respectively. For biochemically disease free patients, the median posttreatment PSA level was < 0.1 ng/mL. When the group was stratified by the dominant histologic pattern, no statistical difference in outcome was noted for any of the evaluated parameters. In forward conditional Cox regression analysis, pretreatment PSA level and percent positive biopsy results were statistically significant predictors of biochemical outcome. CONCLUSIONS In hormone-naive patients with a Gleason score of 7, prostate brachytherapy results in a high probability of 8-year biochemical progression-free survival and is independent of Gleason 3 + 4 versus 4 + 3 histology.

Abstract
PURPOSE Pro forms of prostate specific antigen (PSA) have been reported to be more cancer specific markers of prostate cancer than total PSA and they also may preferentially detect the more aggressive forms of the disease. MATERIALS AND METHODS Research immunoassays with high specificity for pro-PSA forms were used to study 1091 retrospective serum specimens, including 555 with 2 to 4 and 536 with 4 to 10 ng/ml PSA, from men enrolled in prostate cancer screening studies who underwent prostate biopsy. RESULTS In the 2 to 4 ng/ml PSA range the ratio of pro- to free-PSA (percent pro-PSA) using a cutoff of 1.8% for recommending prostate biopsy detected 90% of cancers, including 16 of 16 extracapsular tumors and 28 of 29 tumors with a pathology Gleason score of 7 or greater, while avoiding 19% of unnecessary biopsies. Serum percent pro-PSA was significantly increased for Gleason score 7 or greater vs less than 7 (p = 0.0018). In the PSA range of 4 to 10 ng/ml percent pro-PSA had the highest cancer specificity, avoiding 31% of unnecessary biopsies, while detecting 34 of 35 cancers with a pathology Gleason score of 7 or greater and 29 of 31 extracapsular tumors. Neither percent free PSA nor complexed PSA enhanced the detection of aggressive cancers in the 4 to 10 ng/ml PSA range. CONCLUSIONS Percent pro-PSA was superior to percent free and calculated complexed PSA for the detection of prostate cancer in the PSA range of 2 to 10 ng/ml and it had selectivity for detecting more aggressive cancers, as indicated by Gleason score 7 or greater and/or extracapsular tumor extension.

Abstract
BACKGROUND In the current study, the authors sought to further stratify the prognosis of patients with Gleason score (GS) 7 prostate carcinoma. They assessed the influence on outcome of a predominant poorly differentiated Gleason pattern (primary Gleason pattern [GP] 4) and/or a coincident small focus of poorly differentiated tumor of higher grade (tertiary GP 5). METHODS The authors studied 412 patients (mean postoperative follow-up, 33 months) with GS 7 tumors treated with radical prostatectomy at a single Australian campus between November 1989 and December 2002. The chi-square test, Kaplan-Meier method, and Cox proportional hazards analyses were used to evaluate the correlation between primary GP 4 and tertiary GP 5 with the occurrence of adverse pathologic features and disease recurrence. RESULTS In this cohort, 307 patients (75%) had primary GP 3 tumors, 105 (25%) had primary GP 4 tumors, and 17 (2.3%) had a tertiary element of high-grade tumor (GP 5). Patients with primary GP 4 tumors displayed higher rates of seminal vesicle involvement and extraprostatic extension and, along with patients with tertiary GP 5, had significantly shorter times to disease recurrence. Univariate analysis demonstrated that primary GP 4 (P = 0.0003) and tertiary GP 5 (P < 0.0001) were strong predictors of disease recurrence. Primary GP 4 (P = 0.0122) remained an independent predictor of disease recurrence on stepwise multivariate analysis. CONCLUSIONS Primary GP 4 tumors represented an aggressive subset of GS 7 prostate carcinomas. Primary GP was an easily accessible and clinically relevant predictor of disease recurrence in patients with GS 7 prostate carcinoma.
