Kaplan-Meier curves. Arch Intern Med. The impact of BCR on subsequent mortality is uncertain, however, especially given competing causes of death. Overall, BCR was associated with an increased risk of death from prostate cancer in the study population, but the individual probability of this outcome was relatively low. New strategies for defining and managing treatment failure in prostate cancer are needed.
Is there a chance of cure? Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality CSM. J Urol. New strategies for defining and managing treatment failure in prostate cancer are needed. Of note, US veterans receiving care from camcer VA have an approximately 2-fold higher burden of comorbid illness compared with patients in nonveteran health care systems. Genitourinary Cancers. Although a single definition Biochemical failure prostate cancer not Gay pokemon pics for all PCa patients, it is important to define an explicit recommendation that could be easily followed by clinical practitioner. From a meta-analysis on patients treated with metastases-directed therapy for regional and distant recurrences after curative treatment of prostate cancer it was obvious that this approach with either radiotherapy or surgery is promising but still needs validation with a randomised controlled trial.

Men with minimal metastatic nodes undergoing RP with meticulous pelvic lymph node dissection may remain free of BCR longer than 10 years When does it happen? Defining biochemical recurrence of prostate cancer after radical prostatectomy: a proposal for a standardized definition. Drafting of the manuscript : Uchio, Wells, Calderone, Biochejical Concato. Obtained funding : Concato. We therefore generated initial survival curves, showing prostate cancer mortality according to treatment received, reflecting global outcomes.
Radical prostatectomy RP has been used as the main primary treatment for prostate cancer PCa for many years with excellent oncologic results.
- There are two reasons to have a standard definition of second BCR:.
- A biochemical failure is characterized a return of increasing PSA without any other evidence of cancer on a scan.
- In fact, a rising PSA is the gold standard for suspecting prostate cancer recurrence the cancer has come back.
Radical prostatectomy RP has been used as the main primary treatment for prostate cancer PCa for many years with excellent oncologic results. Prostatic specific antigen PSA has been the pivotal tool for recurrence diagnosis, but there is no consensus about the best PSA threshold to define BCR until this moment.
The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy. Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality CSM.
A simple review was made in Medline for articles written in English language about biochemical recurrence after radical prostatectomy. Prostate cancer PCa is the most commom solid-organ male malignancy and second only to lung cancer in mortality in the United States 1.
Radical prostatectomy RP remains the primary treatment for localized PCa and has been performed for many years with excellent oncologic control. Prostatic specific antigen PSA has been used for detection of recurrent disease for more than 35 years 5. Right after its introduction as a BCR marker, men with distinct diseases were treated similarly. Following this trend, individualized treatments emerged and authors proposed different PSA cut-off to define BCR, aiming to intervene in the best moment of PCa recurrence to achieve best perspectives of cure in each patient.
In this way, several BCR criteria were adopted, impairing studies comparison and the practice Amateur nudist penis gallery generalist doctors.
Attempts to standardize BCR definition have been performed in last years, but there is no consensus at this moment 67. Conventional imaging appears to be useless for re-staging PCa after RP at an early enough stage, while new image techniques have been developed, mainly in nuclear medicine area 8.
The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy 9 We reviewed the current medical literature to provide an updated assessment of BCR definition, its meaning, natural history and differences among risk groups.
We selected papers related to BCR after RP and most relevant ones were included in this review aiming to assess differences in BCR definition and the role of each clinical and pathological feature as a risk factor for biochemical and clinical relapse. Therapeutic management of BCR was not addressed in this review. Strict definition of BCR is important to identify patients at risk for disease progression and to enable comparisons among men submitted to CaP treatment in studies. It led to a Consensus Conference in and recommendation statement, last reviewed in Biochemical failure standardization after RP has been studied in more recent years.
However, undetectable value is dependent on the assay used in each institution, thus it is not uniform among the studies. Another consideration to be made is that patients get undetectable PSA level approximately 4 weeks after surgery, as serum half-life of PSA is about 3. A rising serum PSA level after achieving undetectable value is the first sign of reccurent disease. Amling and colleagues analyzed the use of various PSA cut point definitions for determining biochemical progression after RP in They evaluated the percentage of patients with a continued PSA increase after each cut point to define the most appropriate PSA level to determine disease progression.
They concluded PSA 0. InFreedland and colleagues performed a retrospective survey to determine the ideal cutpoint for defining BCR after RP. A series of cutpoints were examined 0.
They determined the ideal cutpoint as the lowest PSA level associated with a high risk of PSA progression in 1 years and 3 years. For PSA levels greater than 0. Further increases in the threshold for failure did not increase progression rates. It led them to conclude that PSA greater than 0. Stephenson and colleagues evaluated metastatic disease progression as primary end-point to determine the best PSA cutpoint for BCR definition. Recent studies have proposed to consider PSA value lesser than 0.
Mir and colleagues stratified patients into favorable and unfavorable groups and suggested a PSA cut-point of 0. More than fifty BCR definitions can be found in the literature Although a single definition is not appropriate for all PCa patients, it is important to define an explicit recommendation that could be easily followed by clinical practitioner.
Median time to BCR ranges from 20 to 38 months 15 Although BCR occurs more often in first 3 years from RP, longer follow-ups are required Bdsm tgp candid a considerable number of patients may recur even after 15 years 20 In a retrospective survey of RP performed from to with a median follow-up of 5.
More recently, in a series comprising almost 2. A single variable is not enough to predict biochemical failure. These variables should be graded into nomograms for accurately predicting BCR. Early detection is necessary to find patients with low-stage disease, Pain in uterus pregnant PSM is the only feature that the surgeon can influence. Thus, the US Preventive Services Task Force re-commendation to omit PSA screening from routine primary care for men concerns us, since incidence of local and regional-stage disease has reduced and distant-stage disease has increased Regarding PSM, we should be careful in the current scenario where surgeons pursue perfect functional preservation in detriment of oncological outcomes, keeping in mind the latter is the primary endpoint.
Rising PSA is the first sign of disease progression after RP, however it does not necessarily lead men to metastatic disease or cancer mortality in few years 1220 This is the key to understand variation among BCR definition. Regardless the BCR definition, it shoud not be used as a landmark to Online teen advice guidance treatments.
They performed a retrospective review of almost two thousand men that underwent RP for localized PCa who had not received adjuvant hormonal treatment before documentation of metastasis. Lamictal used to prevent premature ejaculation with good response to radiotherapy after BCR were also excluded.
After a mean follow-up of 5. Forty four Pageant performance of patients with metastatic disease died due to PCa. Actuarial median time to death after development of metastasis was 5 years. Death time was only influenced by time to metastatic disease after RP Han and colleagues evaluated 2. In a large and multicentric study, Eggener and colleagues used PCa pathological features to predict year cancer specific mortality.
The only parameters significantly associated with PCa mortality were primary and secondary Gleason grades, seminal vesicle status and surgery year. Year of surgery was a relevant risk factor with an improved prognosis in contemporary patients. At low PSA levels that determine BCR, few imaging studies are under investigation to distinguish the sort of recurrence. While new technologies have been incorporated in BCR management, stratifying patients into risk groups is still crutial, as it can determine different prognosis and treatments.
Men with PCa have been classified into low- intermediate- and high-risk Groups for tumor recurrence and disease specific mortality, based on PSA level, clinical or pathological staging and GS. Lymph-node positive pN1 and PSM have also been reported as poor prognosis factors. Risk Group classification predicts biochemical and clinical progression as well as PCa specific mortality and overall survival. The risk of disease progression in these groups has been validated for patients submited to RP in many studies.
In those patients, mortality rates in high and intermediate-risk patients were greater than 11 and 6-fold over low-risk men Therefore, it is crutial to understand the role of each clinical and pathologic feature in PCa BCR and disease progression. PSA is the main biochemical tool for diagnosing and following patients with PCa.
However, its clinical usefulness is limited since a period of 6 months to 2 years of BCR is required for accurate calculation and sometimes treatment decisions should be taken earlier Primary and secondary Gleason grades are associated with higher BCR rates and are significant predictors of metastatic disease and PCa specific mortality 12 Extraprostatic extension pT3a or greater appears to influence BCR, but it is not an independent factor for cancer specific mortality 2223 However, the diference between focal and non-focal EPE has no impact in PCa specific mortality or overall survival 34 Invasion of the seminal vesicles pT3b after RP has historically been associated with a poor prognosis.
It suggests a poorer prognosis in men with pT3b disease in comparisson with pT3a. Although the majority of these men have high-grade disease and worse outcomes, some authors have found a subset of patients with SVI with favorable prognosis.
Some authors Biochemical failure prostate cancer attempted to stratify the number and extent of PSM. Bladder neck margin involvement seems to present greater risk of BCR than other sites Patients with positive node disease have recurrence rates 1. Time to progression is significantly correlated with the number of diseased nodes. Biochemical and clinical relapse time can range from 7 to 28 months and from 24 to 46 months, if we consider patients with one or greater than 2 positive nodes, respectively Median PCa specific survival in those men can be as great as 12 years.
Men with minimal metastatic nodes undergoing RP with meticulous pelvic lymph node dissection may remain free of BCR longer than 10 years Understanding BCR meaning and providing a single definition will help us to standardize and to compare outcomes among studies. PSA relapse help us to guide clinical practice, but it should not be the only feature to determine the therapeutic approach.
There are many variables related to BCR such as GS, pathological stage, surgical margin and lymph-node status. These variables have to be considered together, as they help us to predict local or distant recurrence.
With this in mind, stratifying men with PCa into risk groups is pivotal to define prognosis and treatment. This review provides us an updated assessment of BCR definition and meaning, showing us the differences of BCR rates and clinical outcomes among risk Groups.

Biochemical Failure of Prostate Cancer Treatment – When to Treat and When to Watch. A PSA only recurrence (biochemical failure) post a primary treatment for prostate cancer is relatively common, approximately 30% of those treated! A biochemical failure is characterized a return of increasing PSA without any other evidence of cancer on a scan. Nov 01, · Prostate-specific antigen (PSA) testing became widely available in the United States in the late s, and within a few years of widespread application in clinical practice, at least two new prostate cancer subsets had been "created": PSA failure post–definitive local therapy and PSA progression without overt radiologic evidence of metastases in the setting of castrate levels of Author: Robert Dreicer, Facp. Dec 20, · "Additionally, data showed that 50% of the men who experienced biochemical failure by three years died of prostate cancer as of 15 years, as opposed to DOI: /JCO

It led to a Consensus Conference in and recommendation statement, last reviewed in It suggests a poorer prognosis in men with pT3b disease in comparisson with pT3a. Therapeutic management of BCR was not addressed in this review. Therefore, it is crutial to understand the role of each clinical and pathologic feature in PCa BCR and disease progression. The risk of disease progression in these groups has been validated for patients submited to RP in many studies. For analyses of BCR, complete data were available for men Although not a focus of our analysis, patients receiving radiation therapy, compared with patients receiving surgery, tended to be older with more comorbidities, and have more extensive cancer, higher Gleason scores, and higher PSA values. These and similar reports are both pertinent and important, but the results may not be generalizable to patients receiving other treatments nor to community-based practice. Stephenson and colleagues evaluated metastatic disease progression as primary end-point to determine the best PSA cutpoint for BCR definition. J Natl Compr Canc Netw.
With the introduction of new anatomical and functional imaging modalities, mainly positron emission tomographycomputed tomography PET-CT and multi-parametric magnetic resonance imaging, the eventual origin of biochemical recurrence after curative treatment for prostate cancer can be detected at its earliest stage. Targeted treatment strategies to this local or oligometastatic relapse will be successful in postponing the initiation of systemic treatment, thereby delaying the occurrence of the castrate resistant state and, eventually, improve survival.
December 20, An analysis of the NRG Oncology clinical trial NRG-RTOG showed that the interval of time to biochemical failure IBF , or the time it takes for previously treated cancer to return as indicated by prostate specific antigen PSA rise, could be used as a surrogate endpoint for locally advanced prostate cancer. Previously, surrogate endpoints based on PSA, which are alternate endpoints that could determine the effectiveness of a treatment earlier than traditional clinical endpoints, have been tested and evaluated with radiotherapy and short-term androgen deprivation. However, surrogate endpoints for long-term androgen deprivation, a proven therapy in high-risk, localized cancers, have not been investigated.
