The matrix metalloproteinase-7 polymorphism rs10895304 is associated with increased recurrence risk in patients with clinically localized prostate cancer.

ABSTRACT: To evaluate whether selected high-risk matrix metalloproteinase-7 single nucleotide polymorphisms influence clinicopathologic outcomes in patients with early-stage prostate cancer.Two hundred twelve prostate cancer patients treated with radical prostatectomy were evaluated with a median follow-up of 9.8 years. Genotyping was performed using hybridization with custom-designed allele-specific probes. Three single nucleotide polymorphisms within the matrix metalloproteinase-7 gene were assessed with respect to age at diagnosis, margin status, extracapsular extension, lymph node involvement, recurrence-free survival, and overall survival in paraffin-embedded prostate tissue specimens from patients with early-stage prostate cancer who underwent radical prostatectomy.Rs10895304 was the sole significant polymorphism. The A/G genotype of rs10895304 had a statistically significant association with recurrence-free survival in postprostatectomy patients (p = 0.0061, log-rank test). The frequency of the risk-reducing genotype (A/A) was 74%, whereas that of the risk-enhancing genotypes (A/G and G/G) were 20% and 6%, respectively. Multivariable Cox regression analyses detected a significant association between rs10895304 and recurrences after adjustment for known prognostic factors. The G allele of this polymorphism was associated with increased risk of prostate cancer recurrence (adjusted hazards ratio, 3.375; 95% confidence interval 1.567-7.269; p < 0.001). The other assayed polymorphisms were not significant, and no correlations were made to other clinical variables.The A/G genotype of rs10895304 is predictive of decreased recurrence-free survival in patients with clinically localized prostate cancer. Our data suggest that for this subset of patients, prostatectomy alone may not be adequate for local control. This is a novel and relevant marker that should be evaluated for improved risk stratification of patients who may be candidates for adjuvant radiation therapy to improve local control.

Project description:We have previously demonstrated a significant correlative relationship between PTEN deletion and ERG rearrangement, both in the development of clinically localized prostate cancers and metastases. Herein, we evaluate the cooperative role of ERG and PTEN in oncological outcomes after radical prostatectomy for clinically localized prostate cancer. We evaluated ERG and PTEN status using three previously described cohorts. The first cohort included 235 clinically localized prostate cancer cases represented on tissue microarrays (TMA), evaluated using previously validated FISH assays for ERG and PTEN. The second cohort included 167 cases of clinically localized prostate cancer on TMAs evaluated for PTEN by FISH, and for PTEN and ERG by dual IHC. The third cohort comprised 59 clinically localized prostate cancer cases assessed by array comparative genomic hybridization (aCGH). Kaplan-Meir plots and long rank tests were used to assess the association of ERG and PTEN status with biochemical recurrence after radical prostatectomy for clinically localized prostate cancer. Of the 317 cases eligible for analyses with evaluable ERG and PTEN status, 88 (27.8%) patients developed biochemical recurrence over a median follow-up of 5.7 years. Overall, 45% (142/317) of cases demonstrated ERG rearrangement and 20% (62/317) of cases demonstrated PTEN loss. Hemizygous and homozygous deletion of PTEN was seen in 10% (18/175) and 3% (5/175) of ERG-negative cases, respectively. In contrast, hemizygous and homozygous deletion of PTEN was seen in 11% (15/142) and 17% (24/123) of ERG-positive cases, respectively. PTEN loss (heterozygous or homozygous) was significantly associated with shorter time to biochemical recurrence compared to no PTEN loss (p < 0.001). However, ERG rearrangement versus no rearrangement was not associated with time to PSA recurrence (p = 0.15). Patients who exhibited ERG rearrangement and loss of PTEN had no significant difference in time to recurrence compared to patients with wild-type ERG and loss of PTEN (p = 0.30). Our findings confirm a mutual cooperative role of ERG and PTEN in the pathogenesis of prostate cancer, particularly for homozygous PTEN deletion. ERG did not stratify outcome either alone or in combination with PTEN in this cohort.

Project description:ImportanceThere is a lack of data evaluating the association of surgical delay time (SDT) with outcomes in patients with localized, high-risk prostate cancer.ObjectiveTo investigate the association of SDT of radical prostatectomy and final pathological and survival outcomes.Design, setting, and participantsThis cohort study used data from the US National Cancer Database (NCDB) and identified all patients with clinically localized (cT1-2cN0cM0) high-risk prostate adenocarcinoma diagnosed between 2006 and 2016 who underwent radical prostatectomy. Data analyses were performed from April 1 to April 12, 2020.ExposuresSDT was defined as the number of days between the initial cancer diagnosis and radical prostatectomy. SDT was categorized into 5 groups: 31 to 60, 61 to 90, 91 to 120, 121 to 150, and 151 to 180 days.Main outcomes and measuresThe primary outcomes were predetermined as adverse pathological outcomes after radical prostatectomy, including pT3-T4 disease, pN-positive disease, and positive surgical margin. The adverse pathological score (APS) was defined as an accumulated score of the 3 outcomes (0-3). An APS of 2 or higher was considered a separate outcome to capture cases with more aggressive pathological features. The secondary outcome was overall survival.ResultsOf the 32 184 patients included in the study, the median (interquartile range) age was 64 (59-68) years, and 25 548 (79.4%) were non-Hispanic White. Compared with an SDT of 31 to 60 days, longer SDTs were not associated with higher risks of having any adverse pathological outcomes (odds ratio [OR], 0.95; 95% CI, 0.80-1.12; P = .53), pT3-T4 disease (OR, 0.99; 95% CI, 0.83-1.17; P = .87), pN-positive disease (OR, 0.79; 95% CI, 0.59-1.06; P = .12), positive surgical margin (OR, 0.88; 95% CI, 0.74-1.05; P = .17), or APS greater than or equal to 2 (OR, 0.90; 95% CI, 0.74-1.05; P = .17). Longer SDT was also not associated with worse overall survival (for SDT of 151-180 days, hazard ratio, 1.12; 95% CI, 0.79-1.59, P = .53). Subgroup analyses performed for patients with very high-risk disease (primary Gleason score 5) and sensitivity analyses with SDT considered as a continuous variable yielded similar results.Conclusions and relevanceIn this cohort study of patients who underwent radical prostatectomy within 180 days of diagnosis for high-risk prostate cancer, radical prostatectomy for high-risk prostate cancer could be safely delayed up to 6 months after diagnosis.
