Stroke | Year: 2011

Background and Purpose-Vertigo is a common presenting symptom in ambulatory care settings, and stroke is its leading and most challenging concern. This study aimed to determine the risk of stroke in vertigo patients in a 4-year follow-up after hospitalization for acute isolated vertigo. Methods-The study cohorts consisted of all patients hospitalized with a principal diagnosis of vertigo (n=3021), whereas patients hospitalized for an appendectomy in 2004 (n=3021) comprised the control group and surrogate for the general population. Cox proportional hazard model was performed as a means of comparing the 4-year stroke-free survival rate between the 2 cohorts after adjusting for possible confounding and risk factors. Among vertigo patients, there was further stratification for risk factors to identify the group at high risk for stroke. Results-Of the 243 stroke patients, 185 (6.1%) were from the study cohort and 58 (1.9%) were from the control group. Comparing the 2 groups, patients with vertigo symptoms had a 3.01-times (95% CI, 2.20-4.11; P<0.001) higher risk for stroke after adjusting for patient characteristics, comorbidities, geographic region, urbanization level of residence, and socioeconomic status. Vertigo patients with ≥3 risk factors had a 5.51-fold higher risk for stroke (95% CI, 3.10 -9.79; P<0.001) than those without risk factors. Conclusions-Vertigo patients are at higher risk for stroke than the general population. They should have a comprehensive neurological examination, vascular risk factors survey, and regular follow-up for several years after hospital discharge after treatment of isolated vertigo. © 2010 American Heart Association, Inc.

The European School of Oncology (ESO) Clinical Masterclass is a one-week, full-immersion course, where students and teachers intensively interact with each other. This educational event is designed for medical or clinical oncologists who are defining and orientating their professional careers. Since 2002 nine Masterclasses have been organised in different European cities in which more than 500 oncologists have participated. In this paper, we are presenting data derived from the analysis of the questionnaire distributed to all participants. © 2010 Elsevier Ltd. All rights reserved.

Expert Opinion on Investigational Drugs | Year: 2011

Introduction: Local control is fundamental, both for the curative as well as the palliative treatment of cancer. Tumor treating fields (TTFields) are low intensity (1 2 V/cm), intermediate frequency (100 200 kHz) alternating electric fields administered using insulated electrodes placed on the skin surrounding the region of a malignant tumor. TTFields were shown to destroy cells within the process of mitosis via apoptosis, thereby inhibiting tumor growth. TTFields have no effect on non-dividing cells. Areas covered: This article reviews in vitro and in vivo preclinical studies, demonstrating the activity of TTFields both as a monotherapy as well as in combination with several cytotoxic agents. Furthermore, it summarizes the clinical experience with TTFields, mainly in two indications: one in recurrent glioblastoma multiforme: in a large prospective randomized Phase III trial TTFields was compared with best standard care (including chemotherapy): TTFields significantly improved median overall survival (OS) compared with standard therapy (7.8 vs 6.1 months) for the patients treated per protocol. Importantly, quality of life was also better in the TTFields group. The second indication was a Phase II study in second-line non-small cell lung cancer, where TTFields was administered concomitantly with pemetrexed. This combination resulted in an excellent median OS of 13.8 months. Interestingly, the progression-free survival (PFS) within the area of the TTFields was 28, however, outside the TTFields the PFS was only 22 weeks. Expert opinion: The proof of concept of TTFields has been well demonstrated in the preclinical setting, and the clinical data seem promising in various tumor types. The side effects of TTFields were minimal and in general consisted of skin reaction to the electrodes. There are a number of ways in which TTFields could be further evaluated, for example, in combination with chemotherapy, as a maintenance treatment, or as a salvage therapy if radiotherapy or surgery is not possible. While more clinical data are clearly needed, TTFields is an emerging and promising novel treatment concept. © 2011 Informa UK, Ltd.

Backgroud It is not clear if there is a difference in prognosis between male breast cancer (MBC) and female breast cancer (FBC) patients. The aim of this study was to compare the prognosis of MBC and FBC patients in China and the prognosis of MBC and their corresponding postmenopausal FBC patients. Methods Thirty-five MBC patients who were treated at the Sun Yat-sen University Cancer Center between 1969 and 2004 were enrolled in the study. Seventy FBC patients who were matched with the MBC patients for TNM stage, year of diagnosis, and age at diagnosis were simultaneously enrolled in the study. A second group comprising 18 MBC patients and their corresponding 36 matched postmenopausal FBC patients were also enrolled. The whole group and the postmenopausal groups were compared for five- and ten-year survivals. Results All the factors that could potentially affect prognosis were comparable among the groups except more FBC than MBC patients underwent endocrine therapy and a modified radical mastectomy. The 5- and 10-year survivals in the whole group were 81.6% and 60.3% for men and 90.7% and 73.5% for women (P=0.02). The 5- and 10-year survival in the postmenopausal group was 82.5% and 100% for men and 66.0% and 85.9% for women (P=0.159). Conclusions Chinese FBC patients had a better prognosis than Chinese MBC patients. However, MBC patients and their corresponding postmenopausal FBC patients had a similar prognosis.

Supportive Care in Cancer | Year: 2013

Purpose: New multimodality treatment approaches for prostate cancer require multidisciplinary management of patients. We aimed to assess the current practices of multidisciplinarity and their possible implications in treatment management in Switzerland. Methods: In a survey, urologists and medical oncologists in Switzerland were asked to include at least 25 or 15 consecutive patients with the diagnosis of prostate cancer, respectively. Information about treatment patterns and multidisciplinary parameters of these patients was collected retrospectively. Results: Thirty-seven urologists and 20 oncologists from the French- and German-speaking parts of Switzerland representing 7 out of 11 non-university tertiary centres and 20/10 % of all office-based urologists/oncologists in Switzerland collected data on 1,184 patients. Sixty-five percent of the office-based (16/24 urologists; 6/10 oncologists) and 95 % of the hospital-based (10/11 urologists; 8/8 oncologists) physicians participate in multidisciplinary tumour boards (MTBs). However, only 1.5 % of patients with a new diagnosis of prostate cancer (13 of 883) are discussed at a MTB. Overall, second opinions at diagnosis are requested in 23 % of patients, mainly from radiation oncologists (8.4 %) or fellow urologists (7.4 %). Second opinions are more often requested by urologists who participate at MTBs and in case of advanced stage. Conclusions: Participation at MTBs is high among Swiss urologists and oncologists in private practice and at non-university tertiary centers. In spite of that only a small minority of patietns with prostate cancer are presented at MTBs. © 2013 Springer-Verlag Berlin Heidelberg.
