BACKGROUND In the treatment of prostate carcinoma, radiotherapy and surgery are common choices of comparable efficacy; thus a realistic comparison of the potential long term sequelae, such as the risk of second malignancy, may be of relevance to treatment choice. METHODS Data regarding the rate of incidence from the Surveillance, Epidemiology, and End Results Program cancer registry (1973-199...
Palliative radiotherapy is an effective treatment for the management of symptoms from advanced and metastatic prostate cancer, particularly for relief of pain from bone metastases. In their review, Drs. Boyer, Salama, and Lee concisely examine the data for external beam radiation therapy for uncomplicated bone metastases and cord compression in men with prostate cancer metastatic to bone.[1] Th...
Purpose: In the current study, using different radiobiological models, tumor control probability (TCP) and normal tissue complication probability (NTCP) of radiotherapy plans were calculated for three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT) of prostate cancer.Methods and Materials: 10 prostate plans were randomly selected among patients ...
METHODS We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiothera...
In patients with prostate cancer who have a high risk of pelvic nodal disease, the use elective whole pelvis radiotherapy is still controversial. Two large, randomised, controlled trials (RTOG 9413 and GETUG-01) did not show benefit over prostate-only radiotherapy. 2020, POP-RT trial established role in more than 35% lymph node invasion (known as Roach formula). stressed importance patient sele...
BACKGROUND To investigate the risk of second cancer and radiation induced second cancer following prostate cancer radiotherapy. METHODS We compared men with radiotherapy only with those treated with radical prostatectomy only and those with radiotherapy after radical prostatectomy. Cumulative incidences of second cancers were calculated. Cox analyses were performed to identify determinants in...
BACKGROUND Men treated for clinically localized prostate cancer with either radical prostatectomy or external beam radiotherapy usually survive many years with the side effects of these treatments. We present treatment-specific quality-of-life outcomes for prostate cancer patients 5 years after initial diagnosis. METHODS The cohort consisted of men aged 55-74 years who were newly diagnosed wi...
A case of iris metastasis secondary to prostate cancer is reported and the clinical features of the patient are described. A 75 years old man referred with a right iris tumor , secondary glaucoma and severe anterior uveitis. He had history of multiple bone metastases due to prostate cancer. The iris tumor was diagnosed as prostate cancer metastasis and the literature was searched using medline ...
AIM We combined anti-androgen therapy with radiotherapy in a first-line setting for metastatic prostate cancer aiming to cause maximal cancer-cell death to delay the emergence of castration-resistant disease. MATERIALS AND METHODS In this non-randomized retrospective series of 46 patients, the initial median prostate-specific antigen (PSA) was 98.5 μg/l (range=6.7-15,500), median Gleason scor...
External beam radiotherapy (EBRT) for the treatment of loco-regional prostate cancer yields similar survival rates to radical prostatectomy (10-year survival: 90-95%, 60-70% and 50-60% in T1, T2 and T3-stages, respectively). Post-operative radiotherapy in high-risk prostate cancer may improve the local and distant disease-free survival of patients. Using the recently developed technology of the...
