Resection of colorectal cancer (CRC) metastases provides good survival but is probably underused in real-world practice.A prospective Finnish nationwide study enrolled treatable metastatic CRC patients. The intervention was the assessment resectability upfront and twice during first-line therapy by multidisciplinary team (MDT) at Helsinki tertiary referral centre. primary outcome resection rates survival.In 2012-2018, 1086 patients were included. Median follow-up 58 months. Multiple sites...

Abstract Introduction As the global burden of chronic cancer increases, its correlation to lifestyle, socioeconomic status (SES) and health equity becomes more important. The aim present study was provide a snapshot lifestyle patterns for different types in patients at Nordic tertiary clinic. Materials methods In descriptive observational study, questionnaires addressed highest-attained educational level, occupational economy, relationship status, exposures, habits. questionnaire distributed...

Background and purpose: Health literacy is defined as the ability to find, understand use health information for informed decision. The role of in treatment decisions outcome remains largely unexplored. This study sought out assess effect individual on overall survival (OS) cancer patients Ostrobothnia. Material methods: present a follow-up cross-sectional survey performed during December 2021 March 2022. assessed socioeconomic factors, lifestyle factors self-reported literacy. included data...

Tumour angiogenesis is essential for tumour growth and metastasis. Several lines of evidence indicate that vascular endothelial factor (VEGF) a major regulator both physiological pathological angiogenesis. In this study we assessed the blood vessel density VEGF expression 94 melanoma metastases 70 patients by immunohistochemistry, utilizing antibodies against human platelet cell adhesion molecule-1 (PECAM-1, CD31) VEGF. The number vessels ranged from 4 to 131 vessels/high power field (HPF),...

Background: The Nordic countries are similar in terms of demographics and health care organization. Yet there marked differences lung cancer mortality, for which Denmark historically has had the poorest outcome. One several possible reasons these could have to do with how is diagnosed treated different countries. However, among four most populous countries: Sweden, Denmark, Norway Finland, a paucity knowledge about similarities recommendations national guidelines non-small cell (NSCLC)...

Study Design. A prospective, randomized double-blind comparative trial. Objectives. To evaluate the efficacy and tolerability of nimesulide, a cyclooxygenase (COX)-2–selective anti-inflammatory agent versus ibuprofen in patients with acute lumbosacral back pain. Summary Background Data. Nonsteroidal drugs (NSAIDs) have been more effective than placebo uncomplicated low pain previous controlled trials. The new COX-2–selective drug not yet established.

Abstract Background Prostate cancer is the most common among men, and its diagnosis treatment are improving. Our study evaluated how PSMA-PET/CT prior to planning might improve optimal management of prostate radiotherapy. Methods This retrospective pilot included 43 (PCa) patients referred our radiation oncologist department, from urology for therapy. 18F-PSMA-PET/CT was ordered by oncologists mainly due lack resent image staging. The were divided into three different groups according their...

Many attempts to define a good death have been recorded in the academic literature. In most of these attempts, methods used surveys, interviews, and focus groups. These yielded important information, but they failed provide an opportunity for public deliberation, whereby people engage collectively with issue, consider it from all sides, struggle understand it. We believe that well-orchestrated deliberation could contribute defining death. gathered data four deliberative forums implemented...

Two hundred thirty-seven patients with small cell lung cancer (SCLC), who had responded to induction chemotherapy and radiotherapy, were randomly assigned receive low-dose natural interferon-α (nIFNα) for 6 months; or cycles of maintenance (CAP); no therapy (control group). Although there was difference in median survival between the groups, a significant (p = 0.04) long-term limited disease, favour nIFNα therapy. This finding is now confirmed by further analysis most recent data. Ten...
