The American Cancer Society estimates there will be 220 900 new cases of prostate cancer diagnosed and 28 900 deaths from this disease in the United States in 2003.1 For patients with nonmetastatic prostate cancer, multiple options for management exist 2 including observation,surgery, external beam radiation therapy (EBRT), brachyther apy, or hormonal manipulation with or with- out surgery or radiation therapy (RT).

During the past 50 years, EBRT has been a mainstay in the management of prostate cancer and continues to be used in the treatment of almost 1/3 of all patients receiving definitive therapy.8 Increasing numbers of patients receiving EBRT have been treated with conformal techniques using 3-dimensional (3D) data sets (i.e., CT scans) and now intensity modulated rather than conventional techniques.

The adoption of the prostate specific antigen (PSA) test and its implementation into clinical practice as a screening tool and prognostic and therapeutic measure has increased the number of patients diagnosed and subsequently treated for nonmetastatic disease.9, 10 Importantly pretreatment PSA level has been shown to be the strongest independent predictor of treatment outcome (especially PSA control) after both surgery and radiation. Biochemical disease free survival (bNED control) is defined by a nonrising post-treatment PSA level, while a rising post-treatment PSA level is an early surrogate to a clinical failure many years later. Here we discuss the evolution of EBRT RT tecniques In 2004, there are several different EBRT techniques including conventional EBRT, 3 dimensional conformal radiation therapy (3DCRT), and IMRT. Planning for patients treated with conventional RT is the least complex of these techniques. These patients undergo simulation (planning) and treatment in the supine position. Custom immobilization devices are not commonly utilized. Rectal and bladder contrast and retrograde urethrograms to aid in the localization of the prostate are not mandatory during the simulation.

Treatment fields are usually based upon bony landmarks without the aid of a CT scan. A description of conventional technique used at Fox Chase in the past has been described before. Radiation dose distributions for conventional treatment plans are typically generated in a single plane and the dose is prescribed at the isocenter and normalized at the 100% isodose line. For patients treated with 3DCRT or IMRT, the planning begins first by defining treatment volumes including both the target (prostate) and the surrounding normal structures (bladder and rectum most importantly) based on a 3D data set. Target volumes are defined according to the International Commission on Radiation Units and Measurements (ICRU) report 50. The gross tumor volume (GTV) is considered to be all known disease defined by the planning CT, pertinent imaging or physical exam. The clinical target volume (CTV) is defined as the GTV and any areas containing microscopic disease. In this case, the entire prostate is considered the CTV. Finally, the planning target volume (PTV) is the CTV plus a margin to account for the uncertainties of daily treatment setup and internal organ motion.

DCRT is the process where the radiation dose is planned and delivered so the high dose volume conforms to an accurately defined target volume. This process minimizes the volume of normal tissue receiving a clinically significant radiation dose thereby reducing the probability of normal tissue com plications.

The volume of normal tissue can be further reduced with better target delineation and immobilization of the target (prostate) allowing smaller PTV expansion (i.e., treatment margins).

Patients in this study had to have tumors greater than or equal to 25 cm2. Pilepich et al reported the 8- year update and, as with the previous RTOG study, a significant difference in local failure continued between the two arms (RT + H versus RT alone, P = 0.004). Eight-year local failure rates were 32% and 43%, respectively, between the two groups. An improvement in progression- free survival for the RT + H patients (P = 0.0019) and distant failure (RT + H versus RT alone, P = 0.04) was observed. The apparent benefit of combined androgen suppression and EBRT has led several investigators to examine whether androgen suppression when combined with prostate brachytherapy confers a disease-free survival benefit. D’Amico et al evaluated 1872 men treated with radical prostatectomy or brachytherapy with or without neoadjuvant androgen deprivation or conformal EBRT; 216 were treated with prostate brachytherapy. Of these, 66 had an implant alone and 152 had an implant with androgen suppression. The androgen suppression was 3 months of neoadjuvant luteinizing hormone-releasing hormone agonist preceded by 7 to 10 days of a nonsteroidal antiandrogen. The patients were stratified according to risk groups and Gleason scores. No differences between the two groups of patients were seen except in those patients with Gleason 7. Stone and Stock evaluated 152 men with moderate-risk disease treated with prostate brachytherapy. Seventy of the one hundred and fifty-two men received 5 months of neoadjuvant and adjuvant hormonal deprivation beginning 3 months before the implant. The 4- year, disease-free survival was improved in the androgen-treated group; however, the follow-up was relatively short. Based on a review of the literature, Lee concluded that little evidence exists to support improved disease-free survival in men treated with a combination of androgen suppression and prostate brachytherapy. He has speculated that the possible reasons for this lack of effect may be related to the fact that most men treated with prostate brachytherapy do not have clinical evidence of extracapsular disease, and therefore represent a different population of men than those evaluated in the combination EBRT and androgen suppression trials. Furthermore, the androgen suppression administered in the prostate brachytherapy trials is substantially shorter than the duration of androgen deprivation in trials showing a benefit. Brachytherapy has been given in combination with EBRT. This generally has been reserved for patients with higher stage or grade disease. Radge et al evaluated 229 patients who received I-125 permanent prostate brachytherapy, and divided them into two treatment groups. The first group was treated with an implant alone, whereas the second group was treated with combined EBRT of 45 Gy to the prostate and pelvis followed by an implant 2 weeks after the completion of the EBRT. The 82 patients in this group had higher-risk disease based on clinical stage and Gleason grade. bNED control at 10 years was 79%. E.M. Horwitz et al / Urol Clin N Am 30 (2003) 737–750 739 Grado et al evaluated 490 patients with T1–T3 prostate cancer treated with I-125 and Pd- 103 brachytherapy. Seventy-two patients with T2b or greater disease received adjuvant EBRT. The authors found no evidence of incremental benefit with the addition of EBRT. Rates of disease-free survival in the implant alone and the combination groups were not significantly different, even in multivariate models taking into account differences in disease stage. However, the authors did note that a 72% actuarial, 5- year, disease-free survival was achieved in the combined group, despite the more advanced stage of these patients. The American Brachytherapy Society (ABS) currently recommends adjuvant EBRT for those patients who are felt to be at significant risk for extraprostatic extension. Some authors have advocated trimodality therapy including implant, EBRT, and neoadjuvant hormonal deprivation. Stock and Stone treated 301 patients with T1–T3 prostate cancer with brachytherapy alone or combined with hormonal therapy or EBRT. Forty of these patients were deemed high risk based on a PSA level greater than 15 ng/mL, Gleason score greater than or equal to 8, clinical stage T2c–T3, or positive seminal vesicle biopsy. This group was given combination brachytherapy, EBRT, and 9 months of hormonal therapy. The 3-year biochemical freedom from failure rate in this group was 71%.

The Tribune Chicago in Tuesday studied the program, named Operation Abraham and organized by Project Jerusalem AIDS that sends the Israell surgeon on Swaziland to prepare the doctor on how to execute male cutting on adult and infant in an effort to prevent spreading HIV. The Program - guaranteed Jewish organization U.S.-based Hadassah and the other donors - has sent three delegations surgeon from Israel before Swaziland, Tribune reports Greenberg, Tribune Chicago.

The Representatives of Health in Swaziland, which have smaller than 100 doctors and worldwide most upper spreading HIV, has said this following five times year they hope that offer male cutting 200,000 sexual active mans at a rate of aproximately 200 daily - 20 times faster than the current rate. Some surgeons Swazi have shown that they can each executes 10 procedures of the cutting, which takes beside 25 minutes - daily during casual series of the country event “Saturdays of the Cutting”. According to medical expert, this must take four doctors in each of five separate facilities in country to execute 1,000 cuttings weekly if doctors Swazi can support that to accelerate each weekday the Kaiser Daily HIV/Message of the FACILITIES.

According to Tribune, the Israell surgeons have directed 10 local doctors on how to execute the procedure amongst adult and two others in procedure amongst infant. The Prudence Mkhatshwa, leader nurses in male cutting in Household Assotiation of the Lifes Swaziland, said that preparation helped to raise vastly weekly factor of the adult cutting and that public answer grows. “Before, people were afraid, but now they see the advantage and they interested persons to do this,” Mkhatshwa said, adding these billboards to promote the procedure in addition to use the condom and temperance as method to prevent the transmission HIV.

Shlomo Mor-Yosef, General director Hadassah, said, “This - a part to missions Hadassah’s: outreach on the other place.” Inon Schenker, Director Operation Abraham, said, “Israel is a single country with such experience in mass male cutting, and this can on same important humanitarian call”

Much people, which knows that their sexual partners will well consider that he is in low risk sexual sent infection, including HIV, according to analysis published in June issue Sexual Sent messages of the Diseases, Reytera.

For analysis, Cindy Masaro University British Columbia and colleagues spread the questionnaire on 317 mans and woman, who visitted the clinic IIT for the first time and were not yet diagnosed by IIT. The Questionnaire asked to independently people could be “pretty certainly” sexual pills partner was “safe” in determined circumstance such as if they knew partner well, hear the friends of the partner or confidants they could believe the partner.

The Analysis found that people often scanned subjective measures in determination must sexual partner to place him(it) in raised risk for HIV and other IIT. Much people defined their partner “safety” was founded on how much they have heard the partner or on as intellectual or good-trained partner was. Besides, 70% participant said that they probably must consider the partner “safe” if partner usually was reliable.

According to researcher, the more early studies have found this though much people “sure of their estimation of their symbol of the partner,” their knowledge of their risk of the partner IIT often inexact. Researchers said that interference that “to target suggestions to safety and diffuse wrong beliefs about choice safe partner [are], which it is necessary to promote protection-sexual behaviour” and reduce risk of the issue IIT
