Lower urinary tract infections from external beam radiation therapy in prostate cancer: A single institution experience.

External beam radiation therapy (EMRT) is effective for the treatment of localized prostate cancer. Lower urinary tract infections (LUTIs) are considered one of the main possible adverse events related to External beam radiation therapy. Here we analyzed the incidence of LUTI during EMRT.

Circulating tumor cells correlate with patterns of recurrence in patients with hormone-sensitive prostate cancer.

The aim of this study was to evaluate the correlation between circulating tumor cells (CTCs) and patterns of recurrence in patients with hormone-sensitive prostate cancer. The study involved patients with histologically confirmed, advanced prostatic adenocarcinoma, who were tested for CTCs (Veridex) when they developed recurrence after radical prostatectomy or external beam radiation between 2008 and 2014. Forty-two prostate cancer patients were evaluated.

Isolated Testicular Metastasis from Prostate Cancer.

BACKGROUND Prostatic adenocarcinoma is the most frequently diagnosed carcinoma in the male population; the most common sites of secondary lesions are nodes, bones, and lungs. We report the clinical case of a 58-year-old man presenting with a single metastasis in the left testis after a radical prostatectomy/lymphadenectomy for prostate cancer. CASE REPORT This clinical report focuses on a 58-year-old man with prostate cancer who developed an uncommon single metastasis in the left testis after radical surgery and adjuvant pelvic radiation therapy.

Enteric-coated and highly standardized cranberry extract reduces antibiotic and nonsteroidal anti-inflammatory drug use for urinary tract infections during radiotherapy for prostate carcinoma.

Introduction: Worldwide, bacterial resistance to antibiotic therapy is a major concern for the medical community. Antibiotic resistance mainly affects Gram-negative bacteria that are an important cause of lower urinary tract infections (LUTIs). Pelvic irradiation for prostate cancer is a risk factor for LUTIs.

Efficacy of stereotactic body radiotherapy in oligorecurrent and in oligoprogressive prostate cancer: new evidence from a multicentric study.

Background: The aim of the present study is to evaluate the impact of metastases-directed stereotactic body radiotherapy in two groups of oligometastatic prostate cancer (PC) patients: oligorecurrent PC and oligoprogressive castration-resistant PC (oligo-CRPC).

Methods: Inclusion criteria of the present multicentre retrospective analysis were: (1) oligorecurrent PC, defined as the presence of 1-3 lesions (bone or nodes) detected with choline positron emission tomography or CT plus bone scan following biochemical recurrence; (2) oligo-CRPC, defined as metastases (bone or nodes) detected after a prostatic-specific antigen rise during androgen deprivation therapy (ADT). Primary end points were: distant progression-free survival (DPFS) and ADT-free survival in oligorecurrent PC patients; DPFS and second-line systemic treatment-free survival in oligo-CRPC patients.

Abiraterone acetate and orteronel are two CYP-17 inhibitors that have been studied in prostate cancer. They have shown relevant toxicities, including fluid retention/oedema, hypokalaemia, hypertension, liver function test abnormalities and cardiac events. The goal of this study was to determine the risk of special adverse events related to CYP- 17 inhibitor in patients with metastatic castration-resistant prostate cancer (CRCP).

Neoadjuvant chemotherapy and radical radiotherapy associated with cetuximab for laryngeal cancer in a pancreas and renal recipient.

The oncological treatment for advanced stage head and neck cancer is based on a combination of cisplatin and cetuximab, and radiotherapy. However, very few data are available on this multimodal approach for this type of cancer in pancreas and renal recipients. We report the case of a pancreas and renal recipient being treated with combined chemoradiotherapy for a locally advanced squamous cancer of the larynx.

Artificial microRNAs against the viral E6 protein provoke apoptosis in HPV positive cancer cells.

High-risk human papillomavirus (HPV) types 16 and 18 are associated with more than 70% of cervical cancer cases. The oncoprotein E6 is multifunctional and has numerous cellular partners. The best-known activity of E6 is the polyubiquination of the pro-apoptotic tumor suppressor p53, targeting it for degradation by the 26S proteasome.

Targeting the Two Oncogenic Functional Sites of the HPV E6 Oncoprotein with a High-Affinity Bivalent Ligand.

The E6 oncoproteins of high-risk mucosal (hrm) human papillomaviruses (HPVs) contain a pocket that captures LxxLL motifs and a C-terminal motif that recruits PDZ domains, with both functions being crucial for HPV-induced oncogenesis. A chimeric protein was built by fusing a PDZ domain and an LxxLL motif, both known to bind E6. NMR spectroscopy, calorimetry and a mammalian protein complementation assay converged to show that the resulting PDZ-LxxLL chimera is a bivalent nanomolar ligand of E6, while its separated PDZ and LxxLL components are only micromolar binders.

Clinical evaluation of safety and efficacy of Boswellia-based cream for prevention of adjuvant radiotherapy skin damage in mammary carcinoma: a randomized placebo controlled trial.

Objective: Acute radiation erythema and other skin reactions are common adverse effects experienced by breast carcinoma patients undergoing radiotherapy treatment. Boswellic acids are pentacyclic triterpenes extracted from the resins of the tropical tree Boswellia serrata with strong anti-inflammatory properties. This study was designed to evaluate the safety and the efficacy of the application of a base cream containing boswellic acids in a proprietary formulation (Bosexil(R)) for the prevention and relief of radiation-induced adverse effects in breast cancer patients.

Patients & Methods: Our hospital has conducted two successive named patient NHA programs. A total of 57 patients with progressive CRPC previously treated with first-line docetaxel-based chemotherapy received standard NHA doses: abiraterone acetate 1000 mg once-daily combined with prednisone (5 mg twice daily) or enzalutamide 160 mg once-daily.

Changes in patterns of practice for prostate cancer radiotherapy in Italy 1995-2003. A survey of the Prostate Cancer Study Group of the Italian Radiation Oncology Society.

Aims And Background: In 2002, a survey including 1759 patients treated from 1980 to 1998 established a "benchmark" Italian data source for prostate cancer radiotherapy. This report updates the previous one.

Methods: Data on clinical management and outcomes of 3001 patients treated in 15 centers from 1999 through 2003 were analyzed and compared with those of the previous survey.

Conservative treatment of breast ductal carcinoma in situ: results of an Italian multi-institutional retrospective study.

Background: The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years.

Enteric-coated, highly standardized cranberry extract reduces risk of UTIs and urinary symptoms during radiotherapy for prostate carcinoma.

Background: Cranberry (Vaccinium macrocarpon) proanthocyanidins can interfere with adhesion of bacteria to uroepithelial cells, potentially preventing lower urinary tract infections (LUTIs). Because LUTIs are a common side effect of external beam radiotherapy (EBRT) for prostate cancer, we evaluated the clinical efficacy of enteric-coated tablets containing highly standardized V. msacrocarpon (ecVM) in this condition.

Guidelines for the delineation of nodal regions of the head and neck on axial computed tomography images.

Delineation of target volumes is increasingly recognized as the most crucial step within the process of modern conformal radiotherapy. In the field of head and neck radiation oncology, the need for a standardized methodology in the delineation of nodal regions of the neck on computed tomography (CT) images has recently emerged. To address this issue, a consensus document has been prepared by the Head and Neck Working Party of the AIRO-Lombardia Cooperative Group, based on the proceedings of multidisciplinary meetings and on literature findings.

[Radiotherapy of the breast: changes in the volume of the lung covered in the treatment fields and resulting changes in dose distribution].

In breast cancer adjuvant therapy, respiratory movements continuously modify the irradiated volumes and the anatomical shape of this body region. Fifteen patients were submitted to 3 Computed Tomography (CT) sequences for treatment planning: the first one without any indications to the patient (the standard sequence) and the second and the third one with spontaneous stopped inspiration and expiration, respectively; the patient was always in the same position. The treatment was planned on standard CT images and then applied to the other sequences, maintaining all parameters unvaried, including isocenter position and treatment time.

[Volume of the irradiated small intestine during pelvic radiotherapy. Comparison of various calculation methods].

In pelvic irradiation, the small bowel portion included in the planning treatment volume is one of the major factors of acute enteropathy. Three different methods are used to calculate the bowel volume: Gallagher's grid method and two systems based on specific algorithms using CT data. We compared the results of these different methods in a series of nine patients submitted to treatment volume planning simulation for pelvic irradiation, after oral barium administration.
