Liposarcoma of the spermatic cord is a very rare neoplasm with fewer than 200 cases recorded in world literature. This report describes a case of liposarcoma of the spermatic cord which developed after radical prostatectomy and salvage radiotherapy for prostate cancer treatment. Four years following surgical treatment of the primary neoplasm and one year following radiotherapy, the 67 –year –old patient was referred to the urology clinic for the emergence of a mass in the right hemiscrotum region. Ultrasonography revealed a homogenous isodense mass measuring 4...

Radiotherapy (RT) is one of the most important treatments for prostate cancer. Although RT can kill cancer cells through direct and indirect effects of radiation, it occasionally induces an abscopal effect whereby localized radiation treatment is associated with elimination of metastatic cancer at a distance from the irradiated area. Thus, RT may induce an effective antitumor immune response, although the mechanism involved has remained unclear. The present was designed to evaluate this effect of RT in 36 patients with prostate cancer who provided informed consent prior to enrollment in this clinical trial...

CONTEXT: Local and regional recurrence after radical prostatectomy (RP) can be treated using salvage radiotherapy (SRT). If the recurrence can be delineated on diagnostic imaging, this could allow for increasingly individualized SRT. OBJECTIVE: This systematic review aimed at evaluating the evidence regarding the usefulness of positron emission tomography (PET) and magnetic resonance imaging (MRI) in identifying local and regional recurrences, with the aim to further individualize the SRT treatment...

BACKGROUND: Outcomes with postprostatectomy salvage radiation therapy (SRT) are not ideal. Little evidence exists regarding potential benefits of adding whole pelvic radiation therapy (WPRT) alone or in combination with androgen deprivation therapy (ADT). OBJECTIVE: To explore whether WPRT and/or ADT added to prostate bed radiation therapy (PBRT) improves freedom from biochemical failure (FFBF) or distant metastases (DM). DESIGN, SETTING, AND PARTICIPANTS: A database was compiled from 10 academic institutions of patients with postprostatectomy prostate-specific antigen (PSA) >0...

BACKGROUND: Introducing a new surgical technology may affect behaviors and attitudes of patients and surgeons about clinical practice. Robot-assisted laparoscopic radical prostatectomy (RALP) was approved in 2012 in Japan. We investigated whether the introduction of this system affected the treatment of organ-confined prostate cancer (PCa) and the use of radical prostatectomy (RP). METHODS: We conducted a retrospective multicenter study on 718 patients with clinically determined organ-confined PCa treated at one of three Japanese academic institutions in 2011 (n = 338) or 2013 (n = 380)...

Purpose: Despite the necessity, to date, no detailed database of prostate cancer, especially one that includes clinicopathological data, has been created in Korea. For that reason, the Korean Urological Oncology Society (KUOS) decided to create the Korean Prostate Cancer Database (KPCD). Materials and Methods: The KPCD program was introduced in 2010. After considering regional distribution, a total of 20 hospitals participated in the KPCD. The Database consists of 4 domains (demographic, pretreatment, treatment, and follow-up data) and 135 variables...

Aim: Prostate contouring using CT alone is difficult. To overcome the uncertainty, CT/MRI registration using a fiducial marker is generally performed. However, visualization of the marker itself can be difficult with MRI. This study aimed to determine the optimal MRI pulse sequence for defining the marker as well as the prostate outline among five sequences. Materials and methods: A total of 21 consecutive patients with prostate cancer were enrolled. Two gold fiducial markers were placed before CT/MRI examination...

Background: Target volume delineations for prostate cancer (PCa) salvage radiotherapy (SRT) after radical prostatectomy are usually drawn in the absence of visibly recurrent disease. Gallium-68 Prostate Specific Membrane Antigen Positron Emission Tomography/Computed Tomography ((68)Ga-PSMA-11 PET/CT) detects recurrent PCa with sensitivity superior to standard of care imaging at serum prostate specific antigen (PSA) values low enough to impact target volume delineations for routine SRT. OBJECTIVE: To i) map the recurrence pattern of PCa early biochemical recurrence (BCR) after radical prostatectomy with (68)Ga-PSMA-11 PET/CT in patients with serum PSA levels <1 ng/ml, ii) determine how often consensus clinical target volumes (CTV) based on the Radiation Therapy Oncology Group (RTOG) guidelines cover (68)Ga-PSMA-11 PET/CT-defined disease, and iii) assess the potential impact of (68)Ga-PSMA-11 PET/CT on SRT...

Evidence regarding the effectiveness of treatment for prostate cancer is primarily based on randomized controlled trials. Long-term outcomes are generally difficult to evaluate within experimental studies and may benefit from large pools of observational data. We conducted a systematic review of administrative and registry studies to evaluate the comparative effectiveness of treatment for clinically localized prostate cancer on overall and prostate-cancer specific mortality. MATERIALS AND METHODS: In accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P, 2015), we conducted a systematic search of Ovid Medline and Embase (1946-February 2017) and identified studies that evaluated the relationship between types of treatment for localized prostate cancer and mortality...

Background: Cancer patients tend to use more and more complementary or alternative medicine concomitantly to radiotherapy. A large part of these patients have recourse to Mind and Body practice, mainly with biofield healers or magnetizers, without any level of evidence. The aim of the present study was to report epidemiologic data on biofield healers in radiation therapy patients, and to assess the possible objective and subjective benefits. Materials and Methods: A retrospective study was conducted in a French cancer institute...

Prostate cancer treatment is currently based on surgical removal, radiotherapy, and hormone therapy. In recent years, another therapeutic method has emerged-immunological treatment. Immunotherapy modulates and strengthens one's immune responses against cancer. Neoplastic cells naturally escape from the control of the immune system, and the main goal of immune therapy is to bring the control back. Satisfying outcomes after treatment of advanced melanoma and lung cancer suggest a great potential of immunotherapy as an approach for other tumors' treatment, especially in patients primarily introduced to palliative care...
