Study Compares Surgery, Radiation, and Active Monitoring to Treat Prostate Cancer

This study will help inform that discussion for men making what is a highly personal, and often difficult choice,” said Brawley.The study involved about 1,600 men in the United Kingdom aged 50 to 69 who were diagnosed with prostate cancer after having an elevated PSA test result. The men were assigned randomly to get surgery to remove their prostate, external-beam radiation, or active monitoring.While the results showed no difference in death from prostate cancer among the groups after 10 years of monitoring, it remains to be seen whether differences will show up after a longer follow-up period. This could be especially important for younger men diagnosed with prostate cancer, who could potentially live several more decades after their diagnosis.The study was published online September 14, 2016 in the New England Journal of Medicine.Citations: 10-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Localized Prostate Cancer.

awa M Abstract Interventional therapies are emerging modalities for the treatment of localized prostate cancer. Their aim is to reduce the morbidity associated with radical therapies (rT) by minimizing damage to non-cancerous tissue, with priority given to sparing key structures such as the neurovascular bundles, external sphincter, bladder neck, and rectum, while maintaining local cancer control. Interventional ablative technologies deliver energy in different ways to destroy cancer cells. The most widely investigated techniques are brachytherapy, external beam radiotherapy, cryotherapy, and high-intensity focuse...

We present 3 cases with false-negatives for local (recurrent) prostate cancer on 68Ga-PSMA PET/CT, using multiparametric MRI and histopathology as reference standard. Metal artifact of prostate gold markers placed for external beam radiation therapy, low level of PSMA uptake, and bladder spillover are potential causes of misinterpretation. Awareness of these diagnostic pitfalls may improve 68Ga-PSMA PET/CT interpretation.

ConclusionsAnalyses according to treatment received showed increased rates of disease-related events and lower rates of patient-reported harms in men managed by AM compared with men managed by radical treatment, and stronger evidence of greater PCa mortality in the AM group.Patient summaryMore than 95 out of every 100 men with low or intermediate risk localised prostate cancer do not die of prostate cancer within 10 yr, irrespective of whether treatment is by means of monitoring, surgery, or radiotherapy. Side effects on sexual and bladder function are better after active monitoring, but the risks of spreading of pros...

ConclusionDifferent medical physicists or dosimetrists, photon energies, treatment planning systems, and treatment machines have an impact on the resulting dose distribution. However, the differences only become apparent when comparing DVH, analysing dose values, comparing CI, HI, GI, as well as reviewing the dose distribution in every single plane. A  new score was introduced to identify treatment plans that simultaneously deliver a low dose to all OAR. Such inter- and intra-institutional comparison studies are needed to explore different treatment planning strategies; however, there is still no automatic soluti...

Conclusions: Insertion of HS in prostate cancer patients receiving combined HDR and EBRT is safe and has resulted in a significant radiation dose reduction to the rectum, resulting in significantly less acute GI toxicity and a trend towards less late GI toxicity. PMID: 30911304 [PubMed]

CONCLUSIONS: In our study, we found that PC patients treated with EBRT had an increased incidence of SC compared to the general population. Patients treated with EBRT and RT after RP were found to have increased risk of SCs, using RP patients as reference. The risks of rectal and urinary bladder cancer in patients receiving EBRT were higher compared to both the general population and to patients treated with radical prostatectomy. The risk of SC should be taken into account when discussing treatment for patients and designing follow-up. PMID: 30905229 [PubMed - as supplied by publisher]

AbstractBackgroundThe impact of different radiotherapy modalities on the development and characteristics of second primary bladder cancers (BCa) and BCa-specific mortality (BCa-SM) remains unclear. Thus, we evaluated the incidence and biological behavior of subsequent BCa and related survival in patients who underwent radiation therapy for prostate cancer (PCa).MethodsA total of 530,581 patients in the surveillance, epidemiology, and end results database with localized PCa between 1988 and 2013 were identified. PCa treatments included radical prostatectomy (RP), external beam radiotherapy (EBRT), radioactive implants (RI),...

Abstract External beam radiation therapy for prostate cancer can result in urinary, sexual, and rectal side effects, often impairing quality of life. A polyethylene glycol-based product, SpaceOAR© hydrogel (SOH), implanted into the connective tissue between the prostate gland and rectum can significantly reduce the dose received by the rectum and hence risk of rectal toxicity. The optimal way to manage the hydrogel and rectal structures for plan optimization is therefore of interest. In 13 patients, computerized tomography (CT) scans were taken pre- and post-SpaceOAR© implant. A prescription of 60 G...

Authors: Pianou NK, Stavrou PZ, Vlontzou E, Rondogianni P, Exarhos DN, Datseris IE Abstract Prostate cancer (PCa) is the most common solid cancer affecting men worldwide. Serum prostate-specific antigen (PSA) is at present the most commonly used biomarker for PCa screening, as well as a reliable marker of disease recurrence after initial treatment. Bone metastases (BM) are present in advanced stages of the disease. Imaging of BM is important not only for localization and characterization, but also to evaluate their size and number, as well as to follow-up the disease during and after therapy. Bone metastases format...
