MMP-14 and CD44 in Epithelial-to-Mesenchymal Transition (EMT) in ovarian cancer

Contains fulltext : 170912.pdf (publisher's version ) (Open Access)BACKGROUND: To investigate the expression of MMP-14 and CD44 as well as epithelial-to-mesenchymal transition(EMT)-like changes in ovarian cancer and to determine correlations with clinical outcome. METHODS: In 97 patients with ovarian cancer, MMP-14 and CD44 expression as determined by immunohistochemistry was investigated in relation to EMT-like changes. To determine this, immunohistochemical staining of E-cadherin and vimentin was performed. RESULTS: Patients with expression of both MMP-14 and CD44 in their tumors had a poor prognosis despite complete debulking. Serous histology in advanced-stage tumors (FIGO IIB-IV) correlated with CD44 (rho .286, p < 0.01). Also, CD44 correlated with percentage vimentin expression (rho .217, p < 0.05). In logistic regression analysis with complete debulking as the outcome parameter, CD44 expression was found to be significant (OR 3,571 (95 % Confidence Interval 1,112-11,468) p = 0.032), though this was not the case for MMP-14 and EMT parameters. CONCLUSION: The subgroup of patients with double expression of MMP-14 and CD44 had a poor prognosis despite complete debulking. Serous subtype in advanced-stage patients and CD44 expression were found to be correlated with vimentin expression, and CD44 expression was found to be significantly correlated with complete debulking. However, a significant correlation between EMT and clinical parameters was not found

Comparison of the antioxidant potential of antiparkinsonian drugs in different in vitro models

Parkinson's disease (PD) is characterized by progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta. Furthermore, oxidative stress plays a role in PD, causing or contributing to the neurodegenerative process. Currently PD has only symptomatic treatment and still nothing can be done to stop the degenerative process of the disease. This study aimed to comparatively evaluate the antioxidant capacity of pramipexole, selegeline and amantadine in different in vitrostudies and to offer possible explanations on the molecular antioxidant mechanisms of these drugs. In vitro, the antioxidant capacity of the drugs was assessed by the ability of antiparkinsonian drugs to decrease or scavenge ROS in the neutrophil respiratory burst, ability of antiparkinsonian drugs to donate hydrogen and stabilize the free radical 2,2-diphenyl-1-picryl-hydrazyl (DPPH•), to scavenge 2,2'-azino-di-(3-ethylbenzthiazoline-6-sulphonic acid (ABTS+) and evaluation of the ferric reducing antioxidant power (FRAP). This study demonstrated that both pramipexole and selegiline, but not amantadine, have antioxidant effects in vitro by scavenging superoxide anion on the respiratory burst, donating electron in the ABTS+ assay and presenting ferric reduction antioxidant power. This chemical structure-related antioxidant capacity suggests a possible neuroprotective mechanism of these drugs beyond their already recognized mechanism of action

Patients' information coping styles influence the benefit of a survivorship care plan in the ROGY care trial: New insights for tailored delivery

Background In efforts to improve the implementation of survivorship care plans (SCPs), the authors assessed whether the impact of SCPs on patient-reported outcomes differed between patients with an information-seeking coping style (monitoring) versus those with an information-avoiding coping style (blunting). Methods In the Registration System Oncological Gynecology (ROGY) Care Trial, 12 hospitals in the Netherlands were randomized to deliver SCP care or usual care. All patients with newly diagnosed endometrial and ovarian cancer in the SCP care arm received an SCP that was generated automatically by their oncology provider through the web-based ROGY registration system. Outcomes (satisfaction with information provision and care, illness perceptions, and health care use) were measured directly after initial treatment and after 6, 12, and 24 months. Information coping style was measured at 12 months after initial treatment. Results Among patients who had a monitoring coping style (N = 123), those in the SCP care arm reported higher satisfaction with information provision (mean score: 73.9 vs 63.9, respectively; P = .04) and care (mean score: 74.5 vs 69.2, respectively; P = .03) compared with those in the usual care arm. Among patients who had a blunting coping style (N = 102), those in the SCP care arm reported a higher impact of the disease on life (mean score: 5.0 vs 4.5, respectively; P = .02) and a higher emotional impact of the disease (mean score: 5.4 vs 4.2, respectively; P = .01) compared with those in the usual care arm. Conclusions SCPs may be beneficial for patients who desire information about their disease, whereas SCPs may be less beneficial for patients who avoid medical information, suggesting a need for tailored SCP delivery to improve survivorship car

Follow-up practice in endometrial cancer and the association with patient and hospital characteristics: a study from the population-based PROFILES registry

Contains fulltext : 118441.pdf (publisher's version ) (Closed access)OBJECTIVE: To examine to what extent endometrial cancer survivors experienced follow-up according to the Dutch national guidelines, and to identify associations between follow-up care consumption and socio-demographic and clinical characteristics, Health-Related Quality of Life (HRQL), and worry (including fear of recurrence). Patients' preferences with the received follow-up care were also evaluated. METHODS: All patients diagnosed with endometrial cancer FIGO stages I-II between 1999 and 2007, registered in the Eindhoven Cancer Registry (ECR), received a questionnaire including patients' follow-up care consumption, preferences regarding the follow-up schedule, HRQL (SF36 and EORTC-QLQ-EN24), and worry (IOCv2). RESULTS: 742 (77%) endometrial cancer survivors returned a completed questionnaire. Overall, 19% reported receiving more follow-up visits than recommended by the guidelines. Overconsumption of follow-up care was lowest in follow-up year 1 (13%), and highest in follow-up years 6-10 (27%). In addition, overconsumption was associated with having a comorbid condition, a higher score on the worry subscale, and hospital of treatment. Most patients (83%) felt comfortable with their follow-up schedule. Patients in follow-up years 6-10 felt least comfortable (69%). CONCLUSION: Follow-up frequency was higher than recommended in a large group of endometrial cancer survivors, mainly in follow-up years 6-10. Moreover, a substantial variation in follow-up practice was observed between the different hospitals. Despite limited evidence to support the use of intensive follow-up schedules, the current study suggests that intensive routine follow-up after endometrial cancer continues to be standard practice. Possibly, patients should be better informed in order to reduce overconsumption and worry

Course of chemotherapy-induced peripheral neuropathy and its impact on health-related quality of life among ovarian cancer patients: A longitudinal study

Objective: Chemotherapy-induced peripheral neuropathy (CIPN) presents itself as sensory peripheral neuropathy (SPN) or motor peripheral neuropathy (MPN). Our aim was to examine the course of SPN and MPN, and their impact on health-related quality of life (HRQoL) among ovarian cancer patients. Methods: All newly diagnosed ovarian cancer patients from twelve hospitals in the South of the Netherlands were eligible for participation. Patients (N=174) completed questions on CIPN (EORTC QLQ-OV28) and HRQoL (EORTC QLQ-C30) after initial treatment and at 6, 12, and 24months (response rates were 70%, 71%, 58%, and 43% respectively). Results: Generalized linear mixed models showed that among chemotherapy-treated patients (N=98), SPN levels were stable over time. For MPN, symptoms significantly improved at 12months. At 2years, 13% still reported high SPN. Also, 11% still reported high MPN. Regarding HRQoL, patients with high SPN reported a worse physical, role, emotional, social, and cognitive functioning compared to those with low SPN. Moreover, those who changed from low to high SPN over time worsened on physical functioning. For MPN, a worse global quality of life and a worse functioning was reported among patients with high MPN. Also, those who changed from low to high MPN over time worsened on global quality of life and on physical, role, social, and cognitive functioning. Conclusions: Among chemotherapy-treated ovarian cancer patients, SPN levels were stable over time. In contrast, MPN symptoms significantly improved at 12months. These symptoms seriously impacted HRQoL. Future studies should examine the impact of different treatment decisions and alterations on CIPN, so recommendations can be made to reduce CIPN (prevalence)

Survivorship Care Plans to inform the primary care physician:Results from the ROGY care pragmatic cluster randomized controlled trial

Purpose This study assesses the effect of sending a Survivorship Care Plan (SCP) to primary care physicians (PCP) on the communication of the PCP with the medical specialist and the patient and to describe PCPs’ opinions regarding the SCP. Methods In a pragmatic cluster randomized controlled trial conducted in 12 hospitals, the PCP of endometrial and ovarian cancer patients received usual information, while in addition the SCP-care arm received a copy of the patient’s SCP. Results A questionnaire was returned by 266 PCPs (76 %). One third of the PCPs in the SCP-care arm indicated having received an SCP. PCPs in the SCP-care arm were more likely to have had personal contact with the medical specialist (52 vs. 37 %, p = 0.01) but were equally satisfied with the information as PCPs in the usual care arm (7.2 vs. 6.9 on a scale from 1 to 10, p = 0.25). Of all PCPs, 82 % indicated they would want to receive an SCP in the future. A quarter of the PCPs who received an SCP reported that the SCP supported contact with the patient. However, the SCP was found too long. Conclusions Supplying an SCP to PCPs potentially has a positive effect on the communication between the PCP and the medical specialist. The SCP should be concise and focused on PCPs’ needs, such as contact information and tailored information on patient diagnosis, treatment, and possible consequences. Implications for Cancer Survivors In the light of transition of cancer care to PCPs, survivors may benefit from improved information provision and communication.

Older ovarian cancer survivors report lower long-term health-related quality of life than younger survivors:A study from the population-based profiles registry

Objective To assess long-term differences in health-related quality of life (HRQoL) of older ovarian cancer survivors compared to both an age-matched normative population and to younger survivors. In addition, the differential effect of chemotherapy on HRQoL between older and younger survivors was compared. Methods Ovarian cancer survivors (n = 348) diagnosed between 2000 and 2010, as registered by the Dutch population-based Eindhoven Cancer Registry, were invited to complete the EORTC QLQ-C30 HRQoL questionnaire in 2012. HRQoL outcomes of survivors were compared with an age-matched normative population and older survivors (≥70 years) were compared with younger survivors. Results The questionnaire was returned by 191 ovarian cancer survivors (55%), 31% were aged ≥70 years (n = 59). Compared to the normative population, survivors ≥70 years scored lower on global health status and all functioning subscales except emotional functioning, and they reported more symptoms. Survivors aged <70 years only reported worse physical and cognitive functioning in comparison with the normative population. Most differences were of medium to small clinical relevance. Age appeared to moderate the effect of chemotherapy on HRQoL. Older survivors who had received chemotherapy experienced better physical functioning and less pain and insomnia while the opposite was found in younger survivors. Conclusion In comparison with an age-matched normative population, older ovarian cancer survivors report lower HRQoL scores than younger survivors. As this represents a selection of long-term survivors, future research should focus on the trajectory of HRQoL from diagnosis throughout treatment and follow-up to identify which factors are related to worse HRQoL in the entire older ovarian cancer population and whether timely interventions are able to improve HRQoL

Factors influencing implementation of a Survivorship Care Plan: A quantitative process evaluation of the ROGY Care Trial

Purpose The aim of this study is to investigate the factors that influence implementation of Survivorship Care Plans (SCPs) in the intervention arm of the ROGY Care trial by (1) assessing the level of SCP receipt in the ROGY Care trial and (2) identifying patient- and provider-level factors that influence SCP receipt. Methods Between 2011 and 2015, a pragmatic cluster randomized-controlled-trial was conducted on the effects of automatically generated SCPs. Endometrial (N = 117) and ovarian (N = 61) cancer patients were allocated to ‘SCP care’, as provided by their SCP care providers (N = 10). Associations between SCP receipt (self-reported SCP receipt and actually generated SCPs), patient-factors (socio-demographic-, clinical-, and personality factors), and care provider factors (profession and a-priori motivation regarding SCP provision) were tested in univariate analysis. The odds ratios of factors influencing self-reported SCP receipt were estimated with a multivariate regression model. Results Of all patients in the SCP care arm (N = 178), SCPs were generated by the care provider for 90 % of the patients and 70 % of the patients reported that they had received an SCP. Patients with older age, ovarian cancer, type D (distressed) personality, and patients that completed the questionnaire a longer period of time after the SCP consult were more likely to report no SCP receipt. Conclusions SCP receipt was influenced by patient- but not care-provider factors. Implications for cancer survivors Certain patient groups were less likely to report SCP receipt. Whether all patients are in need of an SCP, requires further investigation. If they do, more efforts need to be made towards the implementation of SCPs
