Outcomes of locally advanced prostate cancer:a single institution study of 209 patients in Japan

Aim： To investigate the outcomes for Asian populations with locally advanced/clinical stage Ⅲ prostate cancer （PCa） treated with currently prevailing modalities. Methods： We reviewed the record of 209 patients with clinical stage Ⅲ PCa, who were treated at Niigata Cancer Center Hospital between 1992 and 2003. Treatment options included hormone therapy-combined radical prostatectomy （RP＋HT）, hormone therapy-combined external beam irradiation （EBRT＋HT） and primary hormone therapy （PHT）. Results： The 5- and 10-year overall survival rates were 80.3% and 46.1% in all cohorts, respectively. The survival rates were 87.3% and 66.5% in the RP＋HT group, 94.9% and 70.0% in the EBRT＋HT group and 66.1% and 17.2% in the PHT group, respectively. A significant survival advantage was found in the EBRT＋HT group compared with that in the PHT group （P 〈 0.0001）. Also, the RP＋HT group had better survival than the PHT group （P = 0.0107）. The 5- and 10-year disease-specific survival rates for all cases were 92.5% and 80.0%, respectively. They were 93.8% and 71.4% in the RP＋HT group, 96.6% and 93.6% in the EBRT＋HT group and 88.6% and 62.3% in the PHT group, respectively. A survival advantage was found in the EBRT＋HT group compared with the PHT group （P = 0.029）. No significant difference was found in disease-specific survival between the EBRT＋HT and RP＋HT groups or between the RP＋HT and PHT groups. Condusion： Although our findings indicate that radiotherapy plus HT has a survival advantage in this stage of PCa, we recommend therapies that take into account the patients＇ social and medical conditions for Asian men with clinical stage Ⅲ PCa.

The role of radiotherapy in localised and locally advanced prostate cancer

For a patient suffering from non-metastatic prostate cancer,the individualized recommendation of radiotherapy has to be the fruit of a multidisciplinary approach in the context of a Tumor Board,to be explained carefully to the patient to obtain his informed consent.External beam radiotherapy is now delivered by intensity modulated radiotherapy,considered as the gold standard.From a radiotherapy perspective,low-risk localized prostate cancer is treated by image guided intensity modulated radiotherapy,or brachytherapy if patients meet the required eligibility criteria.Intermediate-risk patients may benefit from intensity modulated radiotherapy combined with 4e6 months of androgen deprivation therapy;intensity modulated radiotherapy alone or combined with brachytherapy can be offered to patients unsuitable for androgen deprivation therapy due to co-morbidities or unwilling to accept it to preserve their sexual health.High-risk prostate cancer,i.e.high-risk localized and locally advanced prostate cancer,requires intensity modulated radiotherapy with long-term(≥2 years)androgen deprivation therapy with luteinizing hormone releasing hormone agonists.Post-operative irradiation,either immediate or early deferred,is proposed to patients classified as pT3pN0,based on surgical margins,prostate-specific antigen values and quality of life.Whatever the techniques and their degree of sophistication,quality assurance plays a major role in the management of radiotherapy,requiring the involvement of physicians,physicists,dosimetrists,radiation technologists and computer scientists.The patients must be informed about the potential morbidity of radiotherapy and androgen deprivation therapy and followed regularly during and after treatment for tertiary prevention and evaluation.A close cooperation is needed with general practitioners and specialists to prevent and mitigate side effects and maintain quality of life.

Perioperative complications of radical retropubic prostatectomy in patients with locally advanced prostate cancer： a comparison with clinically localized prostate cancer

Radical prostatectomy （RP） continues to be an effective surgical therapy for prostate carcinoma, particularly for organ-confined prostate cancer （PCa）. Recently, RP has also been used in the treatment of locally advanced prostate cancer. However, little research has been performed to elucidate the perioperative complications associated with RP in patients with clinically localized or locally advanced PCa. We sought to analyse the incidence of complications in these two groups after radical retropubic prostatectomy （RRP）. From June 2002 to July 2010, we reviewed 379 PCa patients who underwent RRP in our hospital. Among these cases, 196 had clinically localized PCa （Tla-T2c group 1）, and 183 had locally advanced PCa （ ≥ T3,： group 2）. The overall complication incidence was 21.9%, which was lower than other studies have reported. Perioperative complications in patients with locally advanced PCa mirror those in patients with clinically localized PCa （26.2% vs. 17.8%, P=0.91）. Our results showed that perioperative complications could not be regarded as a factor to consider in regarding RP in patients with cT3 or greater.

Estrogen receptor （α and β） but not androgen receptor expression is correlated with recurrence, progression and survival in post prostatectomy T3NOMO locally advanced prostate cancer in an urban Greek population

The objective of this study was to evaluate the expression of estrogen receptors （ER（（α ） and ER（β）） and androgen receptors （ARs） as prognostic factors for biochemical recurrence, disease progression and survival in patients with pT3NOMO prostate cancer （PCa） in an urban Greek population. A total of 100 consecutive patients with pT3NOMO PCa treated with radical prostatectomy participated in the study. The mean age and follow-up were 64.2 and 6 years, respectively. The HSCORE was used for semi-quantitative analysis of the immunoreactivity of the receptors. The prognostic value of the ER（（α） and ER（β） and AR was assessed in terms of recurrence, progression, and survival. AR expression was not associated with any of the above parameters; however, both ERs correlated with the prognosis. A univariate Cox regression analysis showed that ER（α） positive staining was significantly associated with a greater hazard for all outcomes. Increased ER（β） staining was significantly associated with a lower hazard for all outcomes in the univariate analysis. When both ER HSCORES were used for the analysis, it was found that patients with high ER（α） or low ER（β） HSCORES compared with patients with negatively stained ER（α） and 〉1.7 hSCORE ER（β） had 6.03, 10.93, and 10.53 times greater hazard for biochemical disease recurrence, progression of disease and death, respectively. Multiple Cox proportional hazard analyses showed that the age, preoperative prostate specific antigen, Gleason score and ERs were independent predictors of all outcomes. ER expression is an important prognosticator after radical prostatectomy in patients with pT3NOMO PCa. By contrast, AR expression has limited prognostic value.

Genomic predictors for treatment of late stage prostate cancer

In spite of the development of new treatments for late stage prostate cancer, significant challenges persist to match individuals with effective targeted therapies. Genomic classification using high-throughput sequencing technologies has the potential to achieve this goal and make precision medicine a reality in the management of men with castrate-resistant prostate cancer. This chapter reviews some of the most recent studies that have resulted in significant progress in determining the landscape of somatic genomic alterations in this cohort and, more importantly, have provided clinically actionable information that could guide treatment decisions. This chapter reviews the current understanding of common alterations such as alterations of the androgen receptor and PTEN pathway, as well as ETS gene fusions and the growing importance of PARP inhibition. It also reviews recent studies that characterize the evolution to neuroendocrine tumors, which is becoming an increasingly important clinical problem. Finally, this chapter reviews recent innovative studies that characterize the compelling evolutionary history of lethal prostate cancer evidenced by polyclonal seeding and interclonal cooperation between metastasis and the importance of tumor clone dynamics measured serially in response to treatment. The genomic landscape of late stage prostate cancer is becoming better defined, and the prospect for assigning clinically actionable data to inform rationale treatment for individuals with this disease is becoming a reality.

Identifying the role of apolipoprotein A-I in prostate cancer

Although localized prostate cancer(PCa)can be cured by prostatectomy and radiotherapy,the development of effective therapeutic approaches for advanced prostate cancer,including castration-resistant PCa(CRPC)and neuroendocrine PCa(NEPC),is lagging far behind.Identifying a novel prognostic and diagnostic biomarker for early diagnosis and intervention is an urgent clinical need.Here,we report that apolipoprotein A-I(ApoA-I),the major component of high-density lipoprotein(HDL),is upregulated in PCa based on both bioinformatics and experimental evidence.The fact that advanced PCa shows strong ApoA-I expression reflects its potential role in driving therapeutic resistance and disease progression by reprogramming the lipid metabolic network of tumor cells.Molecularly,ApoA-I is regulated by MYC,a frequently amplified oncogene in late-stage PCa.Altogether,our findings have revealed a novel indicator to predict prognosis and recurrence,which would benefit patients who are prone to progress to metastasis or even NEPC,which is the lethal subtype of PCa.
