Treat workforcets for Patients with Prostate CancerEFFECTIVE TREATMENT FOR PATIENTS WITH PROSTATE CANCER TO  happen upon A BIOCHEMICAL RECURRENCE FREE SURVIVALMariam O. AkinwaleMEDICAL UNIVERSITY OF THE AMERICASMentor Dr. Akintola OdutolaManuscript word  weigh 4205HYPOTHESIS In the  intervention of  strong-growing and metastatic    prostatic gland malignant neoplastic disease, patients who undergo  fundamental prostatectomy with additional  radi otherwiseapy sickness therapy and/or hormonal therapy  provoke  slight  payoff rate in comparison to those who receive  root word prostatectomy solely due to its additive  cure effect.ABSTRACT (word count 275)Hypothesis In the  interference of  pugnacious and metastatic prostate  crab louse, patients who undergo  root word prostatectomy with additional  beam therapy and/or hormonal therapy  make water less recurrence rate in comparison to those who receive  organic prostatectomy alone due to its additive curative effect.Method The clauses rev   iewed in this studies were obtained from PubMed. The database search combined terms from three  themes men above the age of 50, radical prostatectomy, radiation therapy or hormonal therapy and prostate  crab louse remission. This search yielded 72  holds   laterwards inclusion criteria were con steadred. A total of 32  obligates were  utilise for final review  subsequently excluding 40  conditions that did not compargon  counsel options for treatment of prostate malignant neoplastic disease.Result Better life-expectancy have been indicated in patient  enured with  shaft with hormonal therapy compared to patient  treated with radical prostatectomy  however. However, radical prostatectomy and  shaft with hormonal therapy are far  much  streamlined compared to radiotherapy with hormonal therapy. The use of hormonal therapy for treatment of prostate  pubic louse has  unceasingly been frowned at because of its life-threating side  do but its patient-survival rate supersedes that of radic   al prostatectomy as a monotherapy.Conclusion Combination therapy of radical prostatectomy with radiotherapy and hormonal therapy for treatment of patients with either benign or metastatic prostate  flowerpotcer have a  bimestrial life-expectancy than radiotherapy with hormonal therapy, while patients treated with radiotherapy and hormonal therapy have a  weeklong life-expectancy than those with radical prostatectomy with radiotherapy even  afterward considering the side effects of hormonal therapy. Screening tests  may  champion with  primeval detection of biochemical recurrence and  in any case  maintain overtreatment with radiotherapy and/or hormonal therapy after radical prostatectomy.Keywords radical prostatectomy,  appurtenant radiation therapy, hormonal therapy, biochemical recurrence, prostates  pubic louseINTRODUCTIONProstate cancer (PCa) is the second commonest cancer in males above age 60. African- Americans have the highest  prevalence in the US. Risk factors  embarrass d   iets high in beef and milk.Two hundred and thirty-three thousand new cases are diagnosed  every year with 29,480 mortality reported in 2014. (American Cancer Society, 2014) Given these statistics, it is very important to diagnose and treat PC  previous(predicate) in order to reduce the risk of high mortality.Several treatments options are available in the management of PCa. Low- risk prostate cancer is managed by active  watch in order to  stay fresh unnecessary exposure to radiation or surgery. Intermediate or high- risk non-metastatic prostate cancer is treated with prostatectomy or radiation therapy (Zietman et al., 2010). Aggressive and metastatic prostate cancers are treated with variable  combinations of radical prostatectomy (RP), radiation therapy (RT), chemotherapy, cryosurgery, hormonal therapy (HT) and bisphosphates. These combination therapeutic options address the tendency of aggressive PCa to metastasize to neighbouring structures/organs.This study is designed to  mens   urate a  particularized combination of treatment option in the management of aggressive and metastatic PCa. It is hypothesized that patients with aggressive PCa who undergo radical prostatectomy and adjuvant radiotherapy have less recurrence rate compared to those who receive radical prostatectomy alone due to its additive curative effect (Thompson et al., 2013).This study is significant because evidence suggests that different combination treatments of aggressive PCa are associated with different recurrence rate. The identification of the combination therapy with the lowest recurrence rate and longer life-expectancy is essential in this study.I chose this topic because it is important for family practice physicians to have accurate  data to  break dance to their patients regarding best treatment options for aggressive metastatic PCa.METHODThe articles reviewed in this studies were obtained from PubMed. The database search combined terms from  cardinal themes specific population (ol   der men OR men above 50 OR prostate cancer patient OR post prostatectomy patient OR recurrent prostate cancer patient), intervention (prostate cancer adjuvant therapy OR prostate cancer adjuvant radiotherapy OR prostate cancer adjuvant chemotherapy), comparison (radical prostatectomy) and possible outcomes (prostate cancer recurrence OR prostate cancer remission OR prostate cancer curative OR prostate cancer life span OR prostate cancer prognosis OR prostate cancer quality of life).Boolean operators use were OR and AND. OR was used to capture each term within a theme and AND was used to link each theme within parentheses. Filters used were article types (randomized  confineled trial), text availability (free full text), publication dates (5 long  snip), and limited to human.Inclusion criteriaArticles that were include in the systematic review of this study had to meet the following criteria used randomised clinical trials,  age  collection studies and meta-analysis prostate cancer p   opulation radical prostatectomy with adjuvant radiotherapy and hormonal therapy as intervention radical prostatectomy only as comparison and prostate cancer recurrence, prostate cancer remission, prostate cancer curative, prostate cancer life span, prostate cancer prognosis, prostate cancer quality of life as outcome. localised and high risk prostate cancer management were included in the study.Exclusion criteria tribe of women and men below the age of 50 were excluded. Articles published prior to 2011 and were not written in English  wording were excluded. Articles that were not free full text were excluded. Articles that did not compare RP+RT+HT with radical prostatectomy only were excluded.RESULTSThis search yielded 72 articles after inclusion criteria were considered. A total of 27 articles were used for final review after excluding articles that did not compare management options for treatment of prostate cancer.Treatment of Prostate Cancer with Radical Retropubic Prostatectomy    (RRP) And Pelvic Lymph  guest Dissection (PLND)Before we can lay emphasises on other possible treatments to prevent biochemical recurrence (BCR) after RP, we have to talk about RRP and PLND.  correspond to one of the studies cited in this systematic review, ten of 11 patients with histologically confirmed lymph node metastasis (LNM) showed a PSA response ( spend et al., 2015). Three of 10 patients with single LNM had a  perpetrate biochemical remission (median follow-up 72months, range 31.0-83) (Winter et al., 2015). In five cases with single LNM PSA decreased et al., 2015).  wholly of the additionally removed 30 LNs were completely negative (Winter et al., 2015).Treatment of Prostate Cancer with Radical Prostatectomy (RP), PLND and hormonal Therapy (HT)The above combination therapies have been reported to be commonly used for the treatment of metastatic PCa to lymph nodes and other neighboring tissues than  localise PCa due to its higher  ability and potency for the treatment of m   etastatic PCa. The first article I will be talking about under this subtopic had a mean follow-up of 5.3  old age and LNM occurred in 140 patients. An average of 10.9 lymph nodes was dissected from patient with pN1 through a method known as extended sentinel lymph node dissection (eSLND) (Muck et al., 2015). After the surgery, 121 patients with pN1 patients  original adjuvant ADT for a sort period of time (Muck et al., 2015). Average survival year for recurrence-free survival (RFS), RFS after secondary treatment, case-specific survival (CSS), and overall survival (OS) were 4.7, 7.0, 8.8, and 8.1  eld,  individually (Muck et al., 2015). RFS, CSS, and OS were significantly correlated with tumor staging (Muck et al., 2015).The second article focuses on the 67 Chinese patients with lymph node metastasis (LNM) after RP and extended PLND, and these patients received continuous adjuvant ADT. The median follow-up of this study was 46.7 months and  two patients were lost to follow-up. BCR-fr   ee survival was recorded annually indicating 52%, 40%, 22% for the first 3 years respectively and a more significant survival was observed in patients with 5-year BCR free-survival which shows a 93% free-local recurrence, 83% free-systemic metastasis and 96% cancer death-free (Qin et al,2015). Postoperative BCR-free survival was 27.5 months (Qin et al.,2015).Even though a lot of articles support the   corroboratory degree effect of HT as a treatment for PCa, we  besides have to consider the  unfavorable effect of HT including depression.  check to  lee et al, 2015, patients who are treated with ADT have shown to a significant prolonged depressive state (pet al.,2016). The depressive state in correlation coefficient to ADT is confirmed when compared to a control by indicating a p  take to be less than 0.001 (Lee et al.,2016) asunder from the  obstinate effect associated with HT, metastasis have been reported after adjuvant ADT has been used for treatment of both localized and  unsoun   d PCAa (Taguchi et al., 2014). Taguchi et al. reported 9 (4.6%) patients  true metastasis and 6 (3.0%) died from PCa. Eight of nine metastatic patients had a GS greater than 9 and developed a metastasis to the bone, while the remaining one had a GS greater than 7 and developed lymphatic spread (Taguchi et al.,2014).Based on the findings above, optimal timing of  excuse ADT for BCR after RP is crucial. According to a study by Taguchi et al., biochemical recurrence was seen in one patients (2.0%) in the ultra-early group and seen in 12 patients (17.1%) in the early salvage ADT group (Taguchi et al.,2014). Only one patient in the early salvage ADT group developed metastasis to a left supraclavicular lymph node, and no patient died from PCa during follow-up (Taguchi et al.,2014).Treatment of prostate cancer with Radical Prostatectomy (RP) and  beam of light Therapy (RT)In order to examine the effect of RT after RP, an article which compared outcome of patients treated with radiotherapy    after radical prostatectomy and patients who were under active surveillance after radical prostatectomy (Petruzzeillo et al., 2014). Patients who were under surveillance had a longer follow-up but higher recurrence rate and short life-expectancy (Petruzzeillo et al.,2014).  some other article was able to back-up this finding, indicating significant longer life-expectancy and lower risk of recurrence (Gandaglia et al.,2014). However, the earlier administration of radiotherapy after RP is very essential. Studies had if indicated that patients who had ultra-early radiotherapy after RP had lower recurrence and longer life-expectancy (Azelie et al.,2012).A number of reports have associated early RT after RP to decrease risk of BCR and longer overall survival (OS). According to Gandaglia et al, patients with high risk  pit  deriveted more from early radiotherapy compared to patients with lower risk  haemorrhoid (Gandaglia et al.,2014). The risk scores were determined  base on its associat   ion to increasing 5- to 10- year prostates cancer mortality rates with a p value less than 0.001 (Gandaglia et al.,2014). the risk score was associated with increasing 5- and 10-year cancer-specic mortality rates (P et al., 2014).However, adjuvant RT after RP have shown to present with gastrointestinal and genitourinary toxicities. A study indicating the use of real-time tumor-tracking intensity-modulate radiation therapy (RT-IMRT) as a much preferable RT for treatment of PCa with less adverse effects (Shinohara et al.,2013). In patient treated with RT-IMRT have shown to have better quality of life with little or no risk of urinary and intimate dysfunction (Shinohara et al., 2013). No patients treated with RT-IMRT after RP have gastrointestinal discomfort (Azelie et al.,2012). An article has indicated that earlier RT can lower the risk of adverse effect such(prenominal) as gastrointestinal and urinary dysfunction (Hegarty et al.,2015).Another concern is excessive treatment of PCa wi   th RP+RT using standardized guideline. Patients who underwent RT after RP using this standard guideline 27 patients out of 163 patients had recurrence and 3 out 87 with PSAet al.,2014). Hence the other patients were over treated and  thence exposing them to preventable adverse effects.Treatment of Prostate Cancer with Radical Prostatectomy(RP), Radiation Therapy(RT) and Hormonal Therapy (HT)For the treatment of high-risk prostate cancer (PCa) different evidence-based therapies exist such as (RT+HT), (RP+RT), and (RP+RT+HT). RT + HT resulted in a longer life-expectancy which is always greater than 1 compared to RP+RT (Parikh et al.,2012). However, RP+RT+HT combination have a greater than 0.5 longer life-expectancy compared to RT+HT after considering their side effects (Parikh et al.,2012).Treatment of Prostate Cancer with Radical Prostatectomy (RP), Radiation Therapy (RT), Hormonal Therapy (HT) and Neoadjuvant Chemotherapy (NCHT).Patients with local and metastatic PCa are  inclined t   o recurrence after RP. Hence adjuvant therapies are required to reduce biochemical  misfortune and also prolong life-expectancy. Therefore, it is important to study the adverse effect of these combination therapies (RP+RT+HT+NCHT). The major adverse effect associated with these combinations are gastrointestinal and urinary dysfunction while leucopenia and neutropenia mainly for NCHT (Guttilla et al.,2014) and (Thalgotti et al.,2014). Gastrointestinal and urinary dysfunction are seen in low grade pathologically (Guttilla et al.,2014). Thalgotti et al.,2014 reviewed the percentile of blood toxicity after patients have been administered the combination therapies 90% had neutropenia and 53.8% leucopenia in the studied patients (Thalgotti et al.,2014).Effective Screening Test to Aid Prevention of Biochemical Recurrence (BCR)lxxxviii miRNAs were identified to be significantly (p36months) (Bell et al.,2015). Nine miRNAs were identified to be significantly (pet al.,2015). Based on the  susc   eptibility of the above result a new prognostic stick has been created, composed of miRNA-4516 and miRNA-601, Gleason score and lymph node locating (Bell et al.,2015).A study was done to assess which patients would benefit the most from RT after RP using 11C-choline  flatter/CT. In order to identify which patients would benefit the most from restaging 11C-choline PET/CT before RT, 11C-choline PET/CT was  corroborative in 28.4% of patients (172/605) (Castellucci et al, 2016). Castellucci et al.,2016 categorized these patients based on staging Eighty-three of 605 patients were positive locally, 72 of 605 patients had systemic metastasis, and 17 of 605 patients had both local recurrence and systemic metastasis (Catellucci et al., 2016). At multi-analysis PSA, PSA doubling time (PSAdt), and ADT were signicant  bespeakors for positive scan results, whereas PSA and PSAdt were signicantly related to upstage recurrence detection (Pet al.,2016).Genomic classifier (GC) used to predict biochem   ical recurrence and distant metastasis in men receiving radiotherapy (RT) after radical prostatectomy (RP). Illustrating  den et al.,2015, the measurement of GC was used to predict recurrence of PCA at 5 years after receiving RT ( den et al.,2015). A multi-analysis was done which no correlation between GC and PSA before RP. However, patients with low GC had no significance recurrence at 5 years after RT while patients with high GC had recurrence at 5 years after RT (Den et al.,2015).DISCUSSIONThis reviews attempted to answer the question Can adjuvant therapy be used in patients that have undergone radical prostatectomy to prevent local recurrences? The general collective consensus of articles included in this review support the hypothesis that in the treatment of aggressive and metastatic prostate cancer, patients who undergo radical prostatectomy and adjuvant radiotherapy with hormonal therapy have less recurrence rate in comparison to those who receive radical prostatectomy alone    due to its additive curative effect (Parikh et al.,2012 Kyrdalen et al.,2012 Hayachi et al., 2012 Shinohara et al.,2013 Kaplan et al.,2013 Linder et al.,2013 Azelie et al.,2012 Miyake et al.,2014 Taguchi et al.,2014 Muck et al.,2014 Gandaglia et al,2015 Den et al.,2014 Castellucci et al.,2014 Lee M. et al., 2015 Kang et al.,2014 Thalgotti et al.,2014 Sato et al.,2014 Gutilla et al.,2014 Kim et al.,2016 Rosenkrantz et al.,2015 Petruzzeillo et al.,2014Den et al.,2014 Lee J. et al.,2015 Qin et al.,2015 Mizowaki et al,2015 Winter et al.,2015 Bell et al,2015 Hegarty et al.,2015 Den et al., 2015 Taguchi et al.,2014). Only one article concluded that patient with High Gleason score (GS)  protract a risk of bone metastasis and cancer specific-death after RP with ADT (Taguchi et al.,2014). Seven articles laid more emphasise on the combination therapys adverse effects such as gastrointestinal, genitourinary toxicities and sexual dysfunction (Shinohara et al.,2013) and specifically diabetes mel   litus,  kernel disease, osteoporosis (Parikh et al.,2012) and depression for HT (Lee M. et al.,2015). However, few articles addressed these adverse effects by recommending ultra-early RT after RP (Azelia et al.,2012 and Hegarty et al.,2015) and early HT after RP (Taguchi et al.,2014 and Sato et al., 2014).However, early RT after RP does not only reduce gastrointestinal and gastrourinary toxicities but it also prolongs quality-adjusted life expectancy (QALE) and lowers biochemical recurrence (BCR) (Azelie et al.,2012, Sato et al.,2014 and Gandgalia et al.,2014). Radiotherapy such as Real-time tumor-tracking intensity-modulated RT (RT-IMRT) may be a better treatment for localized PCa even though it has a similar effect as RP because of the adverse effects associated with RP such as urinary incontinence and erectile dysfunction (Azelie et al.,2012). Hence, better quality of life with RT compared to RP (Shinohara et al.,2013).An article compared RT after RP with observation alone (OA) a   fter RP which reviewed 87.1% to 30% biochemical progression-free survival, respectively (Petruzzeillo et al.,2014). This result lays further emphasises on the efficacy of RT after RP.Despite all the articles emphasizing the efficacy of adjuvant RT and androgen deprivation therapy (ADT) after RP,  in that location is concern for excessive treatment of PCa using AUA/ASTRO guideline on adjuvant RT. A particular article stretched on the concern by concluding that patients treated with RT who met the AUA/ASTRO guideline should be carefully considered to prevent excessive treatment (Kang et al., 2014). This is because in the article, among 163 patients with high risk BCR according to AUA/ASTRO guideline, only 27 patients developed BCR and treated with RT (Kang et al., 2014). In addition, in 87 patients with pre-operative PSAet al., 2014).Some articles (Gutilla et al,2014 Gutilla et al,2014 and Thalgott et al.,2014) considered the effectiveness of screening test on predicting biochemical f   ailure in order to prevent BCR after RP.Several screening test were considered and tested. Specific miRNA (miR-4516 and miR-601), 11C-Choline PET/CT, Genomic Classifier (GC) and whole-lesion histogram apparent dissemination coefficient (ADC) metric have sensitivity and specificity for BCR after RP (Bell et al.,2015 Castellucci et al.,2015 Den et al.,2015 Den et al.,2014 and Rosenkrantz et al.,2015). These screenings can help to identify specific treatment for BCR, for example, patients with low GC scores are best treated with RT only, whereas those with high GC scores benet from additional therapies (Den et al., 2014).Some studies verified that the trimodality therapy (RP+RT+HT) has shown an increase in quality of life expectancy (QALE) (Parikh et al.,2012 Guttilla et al.,2014 Kyradalen et al.,2012 and Den et al.,2014).Limitations of the search strategy include searching only one database (PubMed), only one source of information is used (database), only published data is included, o   nly data from the last 5 years is included, only articles published in the English language are included, and only one reviewer is reviewing the abstracts. The major  bound of this systematic review is use of more retrospective cohort than clinical trials and use of only free-full articles and also broad question covering several treatment options such as different types of adjuvant radiation therapies, hormonal therapies and inclusion of some chemotherapies.Future research may consider comparing multiple interventions in a single randomized clinical trial with several approaches to allow for better comparison  across clinical outcome measures. Further research may consider more screening test to prevent overtreatment.APPENDICESFirst AuthorDate of PublicationStudy DesignLevel of EvidenceStudy PopulationTherapyOutcomeAzelie C.2012 randomised Clinical trial1b178 patients were referred for daily exclusive image guided IMRT (IG-IMRT) and 69 patients were the control groupIG-IMRT vs RP+I   MRTPatients with low risk PCa treated with IG-IMRT had a more significant outcome compared to the control group (patient treated with RP + IMRT)Bell E.March, 2015Prospective  cohort Study without controls443 patients who undergone RT after RPmiRNAsmiRNA signatures (Notably, two tonic miRNAs miR-4516 and miR-601) can be used as a diagnostic tool to determine patients who will benefit from additional therapy after RP.Castellucci P.Nov., 2015Case series4605 patients treated with RT after RP.RT+RP vs ADT at the time of 11C-choline PET/CTAt the early stage of BCr after RP 11C-choline PET/CT should be suggested before ADT is administered.Den R.March, 2015Randomized Clinical Trials1b188 patients with positive margin of PCa at Thomas Jefferson University and Mayo Clinic between 1990 and 2009 were considered.Neoadjuvant HT, IMRT, salvage RT,  deviceIn patients treated with RT after RP,genomic classifier (GC) was a good prognostic tool for determining metastasis.Den R.August, 2014Randomized C   linical trial1b139 patients who underwent RT after RP that were identified with pT3 or positive prostate margin.Using genetic classifier to predict biochemical failure after RP+RTThe genetic classifier (GC) predicted biochemical failure and metastasis after RP +RT.
