Treatment of newly diagnosed advanced-stage ovarian cancer typically involves cytoreductive surgery and systemic chemotherapy. We conducted a trial to investigate whether the addition hyperthermic intraperitoneal chemotherapy (HIPEC) interval would improve outcomes among patients who were receiving neoadjuvant for stage III epithelial cancer.In multicenter, open-label, phase 3 trial, we randomly assigned 245 had at least stable disease after three cycles carboplatin (area under curve 5 6 mg...

Health-Related Quality of Life (HRQoL) research has typically adopted either a formative approach, in which HRQoL is the common effect its observables, or reflective approach--defining as latent variable that determines observable characteristics HRQoL. Both approaches, however, do not take into account complex organization these characteristics. The objective this study was to introduce new approach for analyzing data, namely network model (NM). An NM, opposed traditional strategies,...

Background: Most cancer survivors are able to return work at some point after diagnosis. However, literature on sustained employability and health-related quality of life (HRQoL) is limited. Therefore, the aims this study were explore influence change in employment status HRQoL long term diagnosis, identify predictors continuation occupationally active survivors.Material methods: We used prospective data (T0 = two years T1 one-year follow-up, T2 two-year follow-up) from a cohort that had an...

Introduction: To facilitate large-scale assessment of a variety cognitive abilities in clinical studies, we developed self-administered online neuropsychological test battery: the Amsterdam Cognition Scan (ACS). The current studies evaluate group adult cancer patients: test–retest reliability ACS and influence setting (home or hospital), relationship between our traditional battery (concurrent validity). Method: Test–retest was studied 96 patients (57 female; Mage = 51.8 years) who completed...

In the randomized open-label phase III OVHIPEC trial, addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery (CRS) improved recurrence-free and overall survival in patients with stage ovarian cancer. We studied cost effectiveness HIPEC CRS cancer.We constructed a Markov health-state transition model measure costs clinical outcomes. Transition probabilities were derived from trial by fitting distributions. Incremental cost-effectiveness ratio (ICER),...

The aim of this work was to assess the association among oral health, general and quality life (QoL). Oral Health Impact Profile (OHIP‐49) RAND‐36 were distributed amongst 118 psychology freshmen. Additionally, two single items self‐rated health (SRGH) (SROH) – administered. Kruskal–Wallis Mann–Whitney U ‐tests used evaluate differences between SRGH SROH categories, regarding OHIP subscale scores RAND scores. More than 75% subjects rated their as good.
