    • What's known on the subject? and What does the study add? Androgen stimulation of prostate cancer (PCa) cells has been the basis for extensive studies evaluating the role of androgen in PCa but the diagnostic measurement of androgen as well as androgen values that potentially influence prognosis are unclear in patients with PCa. The 50 ng/dL threshold has been questioned as a result of reports indicating worse outcomes for levels between 20 and 50 ng/dL. Instead, a 20 ng/dL threshold for serum testosterone after androgren deprivation therapy in patients with advanced PCa was recommended. OBJECTIVE: • Androgen stimulation of prostate cancer (PCa) cells has been extensively studied. The increasing trend of using serum testosterone as an absolute surrogate for castration state means that the diagnostic measurement of testosterone and the values potentially influencing prognosis must be better understood. This is especially important when PCa progresses from an endocrine to an intracrine status. PATIENTS AND METHODS: • We performed a literature review using the MEDLINE database for publications on: (i) hormonal changes with androgen deprivation therapy (ADT); (ii) monitoring hormonal therapy with testosterone measurement; (iii) the efficacy of intermittent androgen deprivation (IAD) compared with continuous androgen deprivation; (iv) the underlying mechanisms of castration-resistance; and (v) novel treatments for castration-resistant PCa (CRPCa). RESULTS: • The optimum serum castration levels to be achieved with ADT are still debated. Recently, the 50 ng/dL threshold has been questioned because of reports indicating worse outcomes when levels between 20 and 50 ng/dL were studied. Instead, a 20 ng/dL threshold for serum testosterone after ADT in patients with advanced prostate cancer was recommended. CONCLUSION: • Understanding the mechanisms of androgen biosynthesis relating to PCa as well as prognostic implications might achieve a consensus regarding the role of ADT for both the androgen-sensitive and -insensitive disease state.

  • Optimizing treatment for men with advanced prostate cancer : expert recommendations and the multidisciplinary approach
  • 2008
  • Ingår i: Critical reviews in oncology/hematology. - 1040-8428 .- 1879-0461. ; 68:Suppl.1, s. S9-S22
  • Forskningsöversikt (refereegranskat)abstract
    • A multidisciplinary panel of 20 international experts, including urologists, radiation oncologists, and medical oncologists, convened during the Advanced Prostate Cancer Multidisciplinary Team meeting in Rome, Italy, in January 2007, to discuss the multidisciplinary team approach and current patterns of care for patients with hormone-refractory prostate cancer (HRPC). During the meeting, the experts discussed several definitions currently used in prostate cancer management, including those for senior adult patients. In addition, the panel reviewed a series of patient case studies in order to provide feedback on current treatment practices and to identify possible strategies for best practice. It was stressed that treatment decisions for senior adult patients should not be based solely on patient age. Additionally, although historically treatment decisions for advanced prostate cancer have focused on palliative care, given the survival benefit associated with docetaxel-based chemotherapy across patient subgroups, more men are likely to be offered chemotherapy for advanced-stage disease in the future.

  • Downsides of Robot-assisted Laparoscopic Radical Prostatectomy: Limitations and Complications
  • 2010
  • Ingår i: European Urology. - : Elsevier. - 1873-7560. ; 57:5, s. 735-746
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Robot-assisted laparoscopic radical prostatectomy (RALP) using the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is now in widespread use for the management of localised prostate cancer (PCa). Many reports of the safety and efficacy of this procedure have been published. However, there are few specific reports of the limitations and complications of RALP. Objective: The primary purpose of this review is to ascertain the downsides of RALP by focusing on complications and limitations of this approach. Evidence acquisition: A Medline search of the English-language literature was performed to identify all papers published since 2001 relating to RALP. Papers providing data on technical failures, complications, learning curve, or other downsides of RALP were considered. Of 412 papers identified, 68 were selected for review based on their relevance to the objective of this paper. Evidence synthesis: RALP has the following principal downsides: (1) device failure occurs in 0.2-0.4% of cases; (2) assessment of functional outcome is unsatisfactory because of nonstandardised assessment techniques; (3) overall complication rates of RALP are low, although higher rates are noted when complications are reported using a standardised system; (4) long-term oncologic data and data on high-risk PCa are limited; (5) a steep learning curve exists, and although acceptable operative times can be achieved in <20 cases, positive surgical margin (PSM) rates may require experience with >80 cases before a plateau is achieved; (6) robotic assistance does not reduce the difficulty associated with obese patients and those with large prostates, middle lobes, or previous surgery, in whom outcomes are less satisfactory than in patients without such factors; (7) economic barriers prevent uniform dissemination of robotic technology. Conclusions: Many of the downsides of RALP identified in this paper can be addressed with longer-term data and more widespread adoption of standardised reporting measures. The significant learning curve should not be understated, and the expense of this technology continues to restrict access for many patients. (C) 2009 European Association of Urology.
