Moderate hypofractionated helical tomotherapy for localized prostate cancer: preliminary report of an observational prospective study.
2019
Objective: To report preliminary findings of a phase II study exploring the clinical outcomes of moderate hypofractionated radiotherapy performed with helical tomotherapy (HT) using computed tomography–magnetic resonance imaging–based planning for localized prostate cancer. Methods: The phase II prospective study received ethics approval from our institutional ethics committee. A dose of 60 Gy/20 fractions for low–intermediate risk prostate cancer by means of HT was explored. Primary endpoints of the study were acute and late gastrointestinal (GI) and genitourinary (GU) toxicities. Secondary endpoints were quality of life and biochemical-free survival. Results: A total of 35 patients were i…
Antimicrobial Lubricant Did Not Reduce Infection Rate in Transrectal Biopsy Patients in a Large Randomized Trial Due to Low Complication Rates
2018
Abstract Background Transrectal prostate biopsy (pbx) is the most frequent outpatient procedure in the urological field. Septic complications are a major health issue. Objective To evaluate complication rates with or without an antimicrobial lubricant. Design, setting, and participants A total of 1000 patients received pbx between 2013 and 2015. Information about complications was collected by a 3-wk questionnaire. Return rate was 73.2% (n = 732). Intervention Randomization for pbx with the instillation of an antimicrobial lubricant (intervention group, n = 385) or the standard lubricant (control group, n = 347) was performed. Outcome measurements and statistical analysis Multivariable anal…
ASSOCIAZIONE DI SERENOA REPENS, URTICA DIOICA E PINUS PINASTER. SICUREZZA ED EFFICACIA NEL TRATTAMENTO DEI SINTOMI DEL BASSO TRATTO URINARIO. STUDIO …
2010
INTRODUCTION. Serenoa repens (saw palmetto) has been employed for the treatment of lower urinary tract symptoms (LUTS) for several years. Its mechanism of action is believed to be due to antiandrogenic, antiproliferative and antinflammatory properties. An association of Serenoa with the nettle “Utica dioica” showing antiproliferative activity and the pine “Pinus pinaster” derivative, showing antinflammatory action, has been proposed in recent years. Such an action is hoped to act not only by reducing LUTS but also by preventing the development of prostate cancer. MATHERIAL AND METHODS. During the years 2007 and 2008, 320 patients suffering from LUTS were treated with an association of Seren…
Targeting human {gamma}delta} T cells with zoledronate and interleukin-2 for immunotherapy of hormone-refractory prostate cancer.
2007
Abstract The increasing evidence that γδ T cells have potent antitumor activity suggests their value in immunotherapy, particularly in areas of unmet need such as metastatic carcinoma. To this end, we initiated a phase I clinical trial in metastatic hormone-refractory prostate cancer to examine the feasibility and consequences of using the γδ T-cell agonist zoledronate, either alone or in combination with low-dose interleukin 2 (IL-2), to activate peripheral blood γδ cells. Nine patients were enlisted to each arm. Neither treatment showed appreciable toxicity. Most patients were treated with zoledronate + IL-2, but conversely only two treated with zoledronate displayed a significant long-te…
PRELIMINARY DATA ON PSA CHANGES DURING INTRAVESICAL THERAPY FOR NON-MUSCLE INVASIVE BLADDER CANCER
2013
Introduction/Aim: Many factors can cause an increase of PSA independently from the presence of prostate cancer . The objective was to evaluate the fluctuation of the serum levels of PSA during adjuvant intravesical chemotherapy or immunotherapy. An increase of PSA due to intravesical BCG and up to 3 months later has been reported (1). Patients and Methods: Patients treated with intravesical chemotherapy or immunotherapy for non- muscle invasive bladder cancer (NMIBC) were entered in the study. Serum samples were collected before starting intravesical therapy, during therapy (within 3rd and 6th instillation) and 30 days after the end of the 6-week induction regimen and during maintenance reg…
Īslaicīgu dzīves kvalitāšu izmaiņu un komplikāciju salīdzinājums pēc atvērtas un laparoskopiskas prostatektomijas
2020
Ievads: Prostatas vēzis ieņem pirmo vietu vīriešiem starp onkoloģiskām saslimšanām Latvijā radikālu prostatektomiju (RP) skaits pieaug. Lokalizēta prostatas vēža ārstēšanai, tiek pielietotas divu veidu procedūras: atvērta un laparoskopiska RP. Ir nepieciešams izvērtēt, kura procedūra sniegs labākus rezultātus pacientam pēc operācijas un mazāk izmainīs dzīves kvalitāti pēc tās. Darba mērķis: Analizēt, kura operācijas pieeja ir ar mazāk komplikācijām un mazāk ietekmē dzīves kvalitāti pacientam. Materiāli un metodes: Prospektīvs pētījums. Tika pielietota aptaujas pētījuma metode. Pacienti iestājās uz plānveida operāciju, ir divas grupas – atvērta RP un laparoskopiska RP. RLP grupā tika iekļaut…
In a randomized trial in prostate cancer patients, dietary protein restriction modifies markers of leptin and insulin signaling in plasma extracellul…
2017
Obesity, metabolic syndrome, and hyperleptinemia are associated with aging and age-associated diseases including prostate cancer. One experimental approach to inhibit tumor growth is to reduce dietary protein intake and hence levels of circulating amino acids. Dietary protein restriction (PR) increases insulin sensitivity and suppresses prostate cancer cell tumor growth in animal models, providing a rationale for clinical trials. We sought to demonstrate that biomarkers derived from plasma extracellular vesicles (EVs) reflect systemic leptin and insulin signaling and respond to dietary interventions. We studied plasma samples from men with prostate cancer awaiting prostatectomy who particip…
Tumor infiltrating T lymphocytes expressing FoxP3, CCR7 or PD-1 predict the outcome of prostate cancer patients subjected to salvage radiotherapy aft…
2016
Tumor immunologic microenvironment is strongly involved in tumor progression and the presence of tumor infiltrating lymphocytes (TIL) with different phenotypes has been demonstrated to be of prognostic relevance in different malignancies. We investigated whether TIL infiltration of tumor tissues could also predict the outcome of prostate cancer patients. To this end, we carried out a retrospective analysis correlating the outcome of locally advanced prostate cancer patients undergone salvage radiotherapy upon relapse after radical surgery with the infiltration by different TIL populations. Twenty-two patients with resectable prostate cancer, with a mean age of 67 (+/−3.93) years, who receiv…
Involvement of Bax and Bcl-2 in induction of apoptosis by essential oils of three Lebanese Salvia species in human prostate cancer cells
2018
Prostate cancer is one of the most common forms of cancer in men, and research to find more effective and less toxic drugs has become necessary. In the frame of our ongoing program on traditionally used Salvia species from the Mediterranean Area, here we report the biological activities of Salvia aurea, S. judaica and S. viscosa essential oils against human prostate cancer cells (DU-145). The cell viability was measured by 3(4,5-dimethyl-thiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) test and lactate dehydrogenase (LDH) release was used to quantify necrosis cell death. Genomic DNA, caspase-3 activity, expression of cleaved caspase-9, B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X (Ba…
