Risk factors for positive surgical margins following radical prostatectomy: review

The presence of positive surgical margins on radical prostatectomy specimen is an adverse prognostic factor. Parameters supposed to influence surgical margin status includes pathology method analysis, surgical technique, tumoral and non tumoral patient parameters, and neoadjuvant hormonal therapy. Regarding the surgical technique, surgeon's experience and neuro-vascular bundles preservation are the most important factors of margin status, whereas surgical approach, bladder neck conservation, intraoperative frozen analysis, and bleeding are minor factors. Non tumoural patient parameters influencing surgical margin status include patient's age and weight, and prostate gland weight. For tumoural parameters, pathological stage and tumour volume are more important factors than the tumor grade and PSA. Five preoperative tumoral risk factors of positive surgical margins are particularly important, including abnormal digital rectal examination, preoperative PSA 10 ng/mL, biopsy Gleason score >7, number of positive biopsy cores > or = 2, and suspicion of extraprostatic extension on radical prostatectomy specimen.

Visual estimation of tumour extent is not an independent predictor of prostate specific antigen recurrence

OBJECTIVE: To analyse tumour extent as a predictor of cancer progression after radical prostatectomy (RP), using a multivariate Cox regression model, as several variables (e.g. Gleason grade and tumour stage) are well-established prognostic factors in prostate cancer but it is uncertain if the visual estimation of tumour extent (percentage of carcinoma) is an independent predictor for prostate cancer recurrence. PATIENTS AND METHODS: Tumour extent was estimated in the RP specimens from 504 men with clinically localized prostate cancer; clinical follow-up data were available for 459 men. The mean (range) follow-up was 44.3 (1.5-144) months. Cancer progression was defined by the development of biochemical recurrence, local recurrence, or distant metastasis. Multivariate analysis was used to assess tumour extent as a predictor of cancer progression. RESULTS: Of the 459 patients, 157 had cancer progression; the mean tumour extent was 36% and 24% in those with and without cancer progression, respectively (P < 0.001). Univariate analysis showed a significant association between the visual estimation of tumour extent and tumour stage, Gleason grade, surgical margins, extraprostatic extension, seminal vesicle invasion, lymph node metastasis, and preoperative serum prostate-specific antigen level (all P < 0.001). However, in a multivariate Cox regression model controlling for pathological stage, Gleason score, and surgical margin status, the visual estimation of tumour extent was no longer a significant predictor of cancer progression (P = 0.84). CONCLUSION: The visual estimation of tumour extent was associated with various established prognostic factors for prostate cancer, and with cancer progression in a univariate analysis, but it was not a significant predictor of cancer progression in the multivariate analysis controlling for pathological stage, Gleason score, and surgical margin status.     

Expression of urokinase-type plasminogen activator system in prostate cancer: correlation with clinicopathological outcomes in patients undergoing radical prostatectomy

The objective of this study was to evaluate the expression levels of urokinase-type plasminogen activator (uPA) system in radical prostatectomy (RP) specimens in order to clarify the significance of the uPA system in prostate cancer. Expression levels of uPA, uPA receptor (uPAR), plasminogen activator inhibitor-1 (PAI-1), and PAI-2 in RP specimens obtained from 153 patients with clinically organ-confined prostate cancer who had not received any neoadjuvant therapies were evaluated by immunohistochemical staining. Various expression levels of uPA, uPAR, PAI-1, and PAI-2 were noted in the majority of prostate cancer specimens. Expression levels of uPA and uPAR were significantly associated with major prognostic indicators, including pathological stage, Gleason score, lymphatic invasion, surgical margin status and lymph node metastasis. However, PAI-1 expression was related to only pathological stage and surgical margin status, and there was no significant association between the expression level of PAI-2 and several parameters examined. Despite the lack of prognostic significance in PAI-2 expression, biochemical recurrence-free survival of patients with strong uPA, uPAR, and PAI-1 expression was significantly lower than that of those with weak uPA, uPAR, and PAI-1 expression, respectively. Furthermore, strong expression of uPA in addition to a Gleason score, positive surgical margin, and lymph node metastasis could be independent predictors for biochemical recurrence after RP. These findings suggest that the uPA system may be involved in the progression of prostate cancer, and that the expression level of uPA in prostate cancer tissue could be used as a useful predictor of biochemical recurrence in patients undergoing RP.     

Variations Among Individual Surgeons in the Rate of Positive Surgical Margins in Radical Prostatectomy Specimens

PurposeCancer at the resection margin (a positive surgical margin) after radical prostatectomy is associated with an increased risk of recurrence even after adjusting for other known risk factors, including pretreatment serum prostate specific antigen (PSA), clinical stage, grade and pathological stage (level of extracapsular extension, seminal vesicle invasion and pelvic lymph node status). Of these prognostic factors only surgical margin status can be influenced by surgical technique. We examined variations in the rate of positive surgical margins among surgeons after controlling for the severity of disease and volume of cases per surgeon.Materials and MethodsA total of 4,629 men were treated with radical prostatectomy by 1 of 44 surgeons at 2 large urban centers between 1983 and 2002 for clinical stage T1-T3NxM0 prostate cancer. Patients were excluded if they had previously received androgen deprivation therapy or radiation therapy to the pelvis. Positive surgical margins were defined as cancer at the inked resection margin. Other risk factors analyzed were serum PSA, grade (Gleason sum), extracapsular extension level (none, invasion into the capsule, present [not otherwise specified], focal extracapsular extension or established extracapsular extension), seminal vesicle invasion, pelvic lymph node metastases, surgery date, surgeon and volume of cases per surgeon.ResultsFor the 26 surgeons who each treated more than 10 patients in the study the rate of positive surgical margins was 10% to 48%. On multivariable analysis higher serum PSA, extracapsular extension level, higher radical prostatectomy Gleason sum, surgery date, surgical volume and surgeon were associated with surgical margin status after controlling for all other clinical and pathological variables.ConclusionsWhile the clinical and pathological features of cancer are associated with the risk of a positive margin in radical prostatectomy specimens, the technique used by individual surgeons is also a factor. Lower rates of positive surgical margins for high volume surgeons suggest that experience and careful attention to surgical details, adjusted for the characteristics of the cancer being treated, can decrease positive surgical margin rates and improve cancer control with radical prostatectomy.     

Limited value of perineural invasion in radical prostatectomy specimens as a predictor of biochemical recurrence in Japanese men with clinically localized prostate cancer

The objective of this study was to determine whether the presence of perineural invasion (PNI) in radical prostatectomy specimens could be a useful prognostic parameter in Japanese men with prostate cancer. Between January 1995 and September 2003, 202 Japanese men underwent radical retropubic prostatectomy for prostate cancer without any neoadjuvant therapies prior to surgery. We retrospectively analyzed the relationship between PNI in radical prostatectomy specimens and other prognostic factors, and also assessed the significance of PNI in biochemical recurrence after radical prostatectomy. The presence of PNI was significantly related to clinical stage, pathological stage, Gleason score, seminal vesicle invasion, lymph node metastasis and tumor volume, but not pretreatment serum prostate specific antigen value. During the observation period, biochemical recurrence occurred in 20 patients (3 in patients without PNI and 17 in those with PNI), and the biochemical recurrence-free survival rate in patients with PNI was significantly lower than that in patients without PNI. In addition to-PNI, pathological stage, seminal vesicle invasion, lymph node metastasis and tumor volume were significantly associated with the biochemical recurrence-free survival rate; however, among these five factors, only seminal vesicle invasion was an independent predictor of biochemical recurrence on multivariate analysis. Despite a significant association between several prognostic parameters, PNI was not an independent predictor of biochemical recurrence; therefore, it may not provide an additive effect to consider the presence of PNI in predicting the prognosis of Japanese men who underwent radical prostatectomy if there are other conventional parameters available.     

Correlation of perineural invasion on radical prostatectomy specimens with other pathologic prognostic factors and PSA failure.

OBJECTIVE: The aim of this study is to evaluate the relationship between perineural invasion (PNI) and other pathologic prognostic factors in radical retropubic prostatectomy (RRP) specimens and also to assess the role of PNI in prostate-specific antigen (PSA) recurrence after RRP. METHOD: 191 consecutive patients had undergone RRP for clinically localized prostate cancer between 1992 and 2000. PNI in RRP specimens and its relation to histopathologic stage and surgical margins is investigated retrospectively. PNI, histopathologic stage, surgical margin status, Gleason score and PSA parameters were used as variables in multivariate analysis for recurrence. RESULTS: PNI is correlated statistically significantly with histopathologic stage, positive surgical margins, specimen Gleason score and recurrence. Mean time to failure was earlier in patients with PNI than patients without PNI (56 vs. 73 months, log-rank 15.67, p<0.001). Lymph node involvement, positive surgical margins and PNI remained as independent predictors of recurrence in multivariate analysis. All patients with PNI, positive surgical margins and lymph node metastasis failed in 6 months. CONCLUSION: PNI is an important prognostic factor that should be taken into consideration in clinical patient management and follow-up after RRP. The presence of PNI together with positive surgical margins and lymph node metastasis may warrant early adjuvant treatment.     

Comparison of tumor- and comorbidity-related predictors of mortality after radical prostatectomy

OBJECTIVES: To identify and compare tumor- and non-tumor-related predictors of survival after radical prostatectomy and to incorporate the latter into the tumor node metastasis classification of prostate cancer. MATERIAL AND METHODS: A total of 402 patients who underwent radical prostatectomy (mean follow-up period 6.9 years) were stratified according to postoperative tumor stage, Gleason score, prostate-specific antigen level, age and five comorbidity classifications. Cox proportional hazard models were used to identify independent prognostic factors predicting overall survival. RESULTS: Comorbidity (American Society of Anesthesiologists Physical Status classification), Gleason score and age, but not tumor stage, were independent predictors of overall survival. Based on tumor stage and the identified independent prognostic factors, an easily applicable prognostic score was developed to predict overall mortality. CONCLUSION: A prognostic classification of radical prostatectomy patients based on Gleason score, comorbidity and age and supplementary to a coarsened variant of the tumor node metastasis classification may be of clinical value.
