Adiposity and Muscle Strength in Men With Prostate Cancer and Cardiovascular Outcomes.

Background: There are limited data on the physical effects of androgen deprivation therapy (ADT) for prostate cancer (PC), and on the relationships of such measures of adiposity and strength to cardiovascular outcomes.

Objectives: The primary objective of this study was to evaluate the relationships of measures of adiposity and strength to cardiovascular outcomes (cardiovascular death, myocardial infarction, stroke, heart failure, arterial revascularization, peripheral arterial disease, and venous thromboembolism) in patients with PC. A secondary objective was to characterize the relationships between ADT use and 12-month changes in these physical measures.

Erdafitinib treatment in metastatic urothelial carcinoma: a real-world analysis.

Background: Erdafitinib, a fibroblast growth factor receptor (FGFR) inhibitor is a standard post chemotherapy advanced treatment line for metastatic urothelial carcinoma harboring FGFR2/3 genomic alterations. It was approved based on a phase 2 clinical trial, revealing a 40% response rate, and 13.8 months overall survival.

Staging Prostate Cancer with Ga-PSMA-11 PET/CT in the Elderly: Is Preimaging Biopsy Imperative?

Although prostate-specific membrane antigen (PSMA) PET/CT has been shown valuable for staging biopsy-proven [B(+)] high-risk prostate cancer, elderly patients are occasionally referred for PSMA PET/CT without a preimaging confirming biopsy [B(-)]. The current study evaluated the rate, clinical characteristics, and PET-based stage of elderly B(-) patients and explored whether biopsy status affects therapeutic approach. One hundred consecutive patients at least 80 y old who underwent staging Ga-PSMA-11 PET/CT were included.

Ga-prostate-specific membrane antigen positron emission tomography/computed tomography for patients with favorable intermediate-risk prostate cancer.

Introduction: Current guidelines do not support the use of pretreatment imaging in patients with favorable intermediate-risk prostate cancer. Ga-prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) is more accurate than conventional imaging for preoperative staging. We aimed to evaluate whether pretreatment Ga-PSMA PET/CT is beneficial for identifying pathological lymph node involvement (LNI) and adverse pathology among patients with favorable intermediate-risk prostate cancer.

Modified Citrus Pectin Treatment in Non-Metastatic Biochemically Relapsed Prostate Cancer: Results of a Prospective Phase II Study.

Optimal therapy of biochemically relapsed prostate cancer (BRPC) after local treatment is elusive. An established modified citrus pectin (PectaSol, P-MCP), a dietary polysaccharide, is an established antagonist of galectin-3, a carbohydrate-binding protein involved in cancer pathogenesis. Based on PSA dynamics, we report on the safety and the primary outcome analysis of a prospective phase II study of P-MCP in non-metastatic BRPC based.

Staging Ga-PSMA PET/CT in 963 consecutive patients with newly diagnosed prostate cancer: incidence and characterization of skeletal involvement.

Purpose: The aim of the study was to elaborate the incidence and type of skeletal involvement in a large cohort of patients with newly diagnosed prostate cancer (PCa) referred for Ga-68 PSMA-11 PET/CT staging in a single center.

Methods: Study cohort included 963 consecutive patients with newly diagnosed PCa referred for Ga-68 PSMA-11 PET/CT study for staging. The incidence of bone involvement, type of bone metastases, and extent of disease were determined and correlated with the ISUP Grade Group (GG) criteria and PSA levels.

[Ga]Ga-PSMA-11 PET/CT for monitoring response to treatment in metastatic prostate cancer: is there any added value over standard follow-up?

Background: The aim of the current study was to assess whether and to what extent monitoring response to treatment using prostate-specific membrane antigen (PSMA)-based positron-emitting tomography/computerized tomography (PET/CT) studies contribute clinically relevant data to routine clinical follow-up during treatment of patients with metastatic prostate cancer (PCa).

Results: Fifty-two patients with metastatic PCa who underwent [Ga]Ga-PSMA-11 PET/CT imaging and serum prostate-specific antigen (PSA) level measurements before and during treatment were investigated. Response was categorized by serum PSA dynamics according to improvement, stable disease, and disease progression and compared to change in imaging findings on pre- and post-treatment PET/CTs.

Biomarker-Driven Therapy in Metastatic Gastric and Esophageal Cancer: Real-Life Clinical Experience.

Objective: To evaluate real-life clinical experience with biomarker-driven therapy in metastatic gastric and esophageal cancer in Israel.

Patients And Methods: This multicenter retrospective cohort study included patients with metastatic gastric or esophageal cancer who were treated in the participating institutions and underwent biomarker-driven therapy.

Imaging response during therapy with radium-223 for castration-resistant prostate cancer with bone metastases-analysis of an international multicenter database.

Background: The imaging response to radium-223 therapy is at present poorly described. We aimed to describe the imaging response to radium-223 treatment.

Methods: We retrospectively evaluated the computed tomography (CT) and bone scintigraphy response of metastatic castration-resistant prostate cancer (CRPC) patients treated with radium-223, in eight centers in three countries.

Outcome of Patients With Metastatic Chromophobe Renal Cell Carcinoma Treated With Sunitinib.

Background: Sunitinib is a standard treatment for metastatic clear cell renal cell carcinoma (mccRCC). Data on its activity in the rare variant of metastatic chromophobe renal cell carcinoma (mchRCC), are limited. We aimed to analyze the activity of sunitinib in a relatively large and homogenous international cohort of mchRCC patients in terms of outcome and comparison with mccRCC.

Metformin Use and Outcome of Sunitinib Treatment in Patients With Diabetes and Metastatic Renal Cell Carcinoma.

Background: Although studies in several cancer types suggest that metformin has antitumor activity, its effect on the outcome of targeted therapies in metastatic renal cell carcinoma (mRCC) is poorly defined. We aimed to analyze the effect of metformin use on the outcome of sunitinib treatment in diabetic patients with mRCC.

Patients And Methods: We performed a retrospective study of diabetic patients with mRCC, who were treated with sunitinib in 8 centers across 2 countries.

D538G mutation in estrogen receptor-α: A novel mechanism for acquired endocrine resistance in breast cancer.

Resistance to endocrine therapy occurs in virtually all patients with estrogen receptor α (ERα)-positive metastatic breast cancer, and is attributed to various mechanisms including loss of ERα expression, altered activity of coregulators, and cross-talk between the ERα and growth factor signaling pathways. To our knowledge, acquired mutations of the ERα have not been described as mediating endocrine resistance. Samples of 13 patients with metastatic breast cancer were analyzed for mutations in cancer-related genes.

The protective effect of zoledronic acid on bone loss in postmenopausal women with early breast cancer treated with sequential tamoxifen and letrozole: a prospective, randomized, phase II trial.

Objective: This study reports the efficacy and safety of zoledronic acid (ZOL) in preventing bone loss in postmenopausal patients receiving an aromatase inhibitor (AI) following tamoxifen.

Methods: Postmenopausal patients with stage I-III hormone receptor-positive breast cancer who received tamoxifen for 2.5-3 years were randomized to receive letrozole (2.

Attempts to grow optically coupled Fibonacci-spaced InGaAs/GaAs quantum wells result in surface gratings.

An instability in the growth of nonperiodic InGaAs/GaAs multiple quantum well samples, ordinarily of high-quality when grown with equal periods of order of half the wavelength of light in the material, leads to a dramatic microscopic, self-organized surface grating. This effect was discovered while growing quantum wells with two unequal barrier lengths arranged in a Fibonacci sequence to form an optical quasicrystal. A laser beam incident normal to the surface of the sample is diffracted into a propeller-shaped pattern.

Invasive breast cancer treated with taxol and epirubicin neo-adjuvant chemotherapy: the role in the outcome of the "crosstalk" between Erb receptors and p53.

Purpose: To correlate p53 and ErbB receptors status with disease-free survival (DFS) and overall survival (OS) in locally advanced breast cancer.

Patients And Methods: Sixty patients were included in a single-center, open-label, phase II trial (1998-2003). Analysis of Erb receptors and p53 status and estrogen receptor/progesterone receptor data were available for 33 patients.

Fulvestrant in heavily pretreated metastatic breast cancer: is it still effective as a very advanced line of treatment?

Background: Over 75% of postmenopausal patients with metastatic breast cancer have hormone receptor-positive tumors. Endocrine therapy, with its more favorable toxicity profile than chemotherapy, is the preferred treatment modality for these patients.

Objectives: To assess our experience with fulvestrant, an antiestrogen, in an advanced phase of treatment, after progression on the classical anti-estrogen (tamoxifen) and aromatase inhibitors

Methods: The study group comprised 46 patients with metastatic breast cancer treated with fulvestrant during the years 2002-2006.

Nuclear and cytoplasmic expression of ErbB-4 in prostate cancer.

Purpose: To evaluate cytoplasmic and nuclear ErbB-4 expression in prostate cancer specimens and its association with outcome.

Basic Procedures: Specimens of 50 prostate cancer patients were investigated for ErbB-4 overexpression using Immunohistochemistry staining. Cytoplasmic and nuclear staining was graded as 0-3 according to its intensity.

Neoadjuvant treatment with paclitaxel and epirubicin in invasive breast cancer: a phase II study.

Background And Objectives: The modern management of locally advanced breast cancer includes a multimodal approach consisting of neoadjuvant chemotherapy (usually given as initial treatment), surgery, radiotherapy and adjuvant hormone therapy. This therapeutic approach converts many patients with initially unresectable disease to reasonable surgical candidates, with acceptable rates of loco-regional disease control. Induction of a pathological complete response (pCR) with modern chemotherapy agents or combined with immunotherapy, when applicable, should be one of the primary goals of neoadjuvant therapy in order to achieve better disease-free and overall survival in this subset of patients.

Preoperative clinical, mammographic and sonographic assessment of neoadjuvant chemotherapy response in breast cancer.

Background: The current methods for pre- and post-chemotherapy examination of the extent of disease in the breast and lymph nodes do not provide sufficiently accurate information and, not infrequently, the surgeon has to re-operate.

Objectives: To correlate the findings between three methods of examination (physical examination, ultrasonography, mammography), all performed by the same oncologic and radiologic team, in patients with locally advanced breast cancer or a tumor/breast tissue ratio that precludes breast-conserving surgery.

Methods: Forty patients (median age 48 years, range 24-73) with locally advanced breast cancer or with a tumor/breast ratio that precluded breast-conserving surgery were evaluated by the same medical team and received neoadjuvant chemotherapy.

A biochemotherapy regimen with concurrent administration of cisplatin, vinblastine, temozolomide (Temodal), interferon-alfa and interleukin-2 for metastatic melanoma: a phase II study.

Our objective was to evaluate the toxicity and antitumor efficacy of concurrent biochemotherapy in metastatic melanoma patients and the effectiveness of adding temozolomide to protect the brain from metastases. Twenty-three patients with advanced inoperable melanoma were hospitalized for 5-6 days for the following treatment: cisplatin 20 mg/m daily for 4 days, vinblastine 1.6 mg/m daily for 4 days and oral temozolomide 250 mg/m daily for 5 days, with 18 x 10 IU/m intravenous interleukin-2 by continuous infusion for 4 days (the dose was cut daily by 50%) and 5 x 10 U/m interferon-alfa subcutaneously daily for 5 days, repeated at 28-day intervals for a maximum of nine courses.

Cutaneous and subcutaneous metastases of rectal cancer.

The occurrence of cutaneous metastatic disease from colorectal cancer is uncommon and typically signifies widespread disease with poor prognosis. Colorectal metastases usually occur within the first 3 years of follow up, and the median survival of patients after the appearance of cutaneous metastatic lesions is 18 to 20 months. We describe an unusual case of a 60-year-old woman with a metachronous skin lesion as the sole site of metastatic disease, and a relatively long interval between the appearance of skin metastases and death.

Spontaneous regression of retroperitoneal metastases from a primary pure anaplastic seminoma: a case report.

Spontaneous regression of pure seminoma metastases is a rare phenomenon, with only a few cases reported to date. To the best of our knowledge, this is the first report of regression of anaplastic pure seminoma metastases located in the retroperitoneum. We present a 27-year-old man, a marihuana smoker, with metastatic pure anaplastic seminoma in the high retroperitoneal lymph nodes.
