The indirect costs of palliative care in end-stage cancer : A real-life longitudinal register- and questionnaire-based study

Background: Palliative care needs are increasing as more people are dying from incurable diseases. Healthcare costs have been reported to be highest during the last year of life, but studies on the actual costs of palliative care are scarce. Aim: To explore the resource use and costs of palliative care among end-stage breast, colorectal and prostate cancer patients after termination of life-prolonging oncological treatments, that is, during the palliative care period. Design: A real-life longitudinal register- and questionnaire-based study of cancer patients' resource use and costs. Participants: In total, 70 patients in palliative care with no ongoing oncological treatments were recruited from the Helsinki University Hospital or from the local hospice. Healthcare costs, productivity costs and informal care costs were included. Results: The mean duration of the palliative care period was 179days. The healthcare cost accounted for 55%, informal care for 27% and productivity costs for 18% of the total costs. The last 2weeks of life contributed to 37% of the healthcare cost. The costs of the palliative care period were higher in patients living alone, which was mostly caused by inpatient care (p=0.018). Conclusion: The 45% share of indirect costs is substantial in end-of-life care. The healthcare costs increase towards death, which is especially true of patients living alone. This highlights the significant role of caregivers. More attention should be paid to home care and caregiver support to reduce inpatient care needs and control the costs of end-of-life care.Peer reviewe

Assessing the utilization of the decision to implement a palliative goal for the treatment of cancer patients during the last year of life at Helsinki University Hospital : a historic cohort study

Background: To avoid aggressive treatments at the end-of-life and to provide palliative care (PC), physicians need to terminate futile anti-cancer treatments and define the palliative goal of the treatment in time. This single center study assesses the practices used to make the decision that leads to treatment with a palliative goal, i.e., the PC decision and its effect on anti-cancer treatments at the end of life. Material and methods: Patients with a cancer diagnosis treated in tertiary hospital during 1st January 2013 - 31st December 2014 and deceased by the end of 2014 were identified in the hospital database (N = 2737). Of these patients, 992 were randomly selected for this study. The PC decision was screened from patient records, i.e., termination of cancer-specific treatments and a focus on symptom-centered PC. Results: The PC decision was defined in 82% of the patients during the last year of life (49% >30 days and 33%Peer reviewe

The impact of the duration of the palliative care period on cancer patients with regard to the use of hospital services and the place of death : a retrospective cohort study

Background In order to avoid unnecessary use of hospital services at the end-of-life, palliative care should be initiated early enough in order to have sufficient time to initiate and carry out good quality advance care planning (ACP). This single center study assesses the impact of the PC decision and its timing on the use of hospital services at EOL and the place of death. Methods A randomly chosen cohort of 992 cancer patients treated in a tertiary hospital between Jan 2013 -Dec 2014, who were deceased by the end of 2014, were selected from the total number of 2737 identified from the hospital database. The PC decision (the decision to terminate life-prolonging anticancer treatments and focus on symptom centered palliative care) and use of PC unit services were studied in relation to emergency department (ED) visits, hospital inpatient days and place of death. Results A PC decision was defined for 82% of the patients and 37% visited a PC unit. The earlier the PC decision was made, the more often patients had an appointment at the PC unit (> 180 days prior to death 72% and <14 days 10%). The number of ED visits and inpatient days were highest for patients with no PC decision and lowest for patients with both a PC decision and an PC unit appointment (60 days before death ED visits 1.3 vs 0.8 and inpatient days 9.9 vs 2.9 respectively, p <0.01). Patients with no PC decision died more often in secondary/tertiary hospitals (28% vs. 19% with a PC decision, and 6% with a decision and an appointment to a PC unit). Conclusions The PC decision to initiate a palliative goal for the treatment had a distinct impact on the use of hospital services at the EOL. Contact with a PC unit further increased the likelihood of EOL care at primary care.Peer reviewe

Roles of human epididymis protein 4, carbohydrate antigen 125, inhibin B and anti-Mullerian hormone in the differential diagnosis and follow-up of ovarian granulosa cell tumors

Objective. Evaluation of circulating tumor markers in ovarian cancer is crucial for optimal patient care. The goal of this study was to verify the most accurate circulating tumor markers for the diagnosis and follow-up of adult-type granulosa cell tumors (AGCT5). Methods. The levels of circulating human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125), together with AGCT markers inhibin B and anti-Mtillerian hormone (AMH), were measured in 135 samples from AGCT patients, 37 epithelial ovarian carcinoma (EOC) patients, and 40 endometrioma (ENDO) patients. The levels were plotted with receiver operating characteristic (ROC) graphs, and the area under the curves (AUC) of the different markers were calculated and compared. Results. HE4 levels were significantly lower in AGCT5 than in EOCs (p <0.0001). CA125 levels were above 35 IU/1 in 25% of AGCT patients and 47.5% of ENDO patients, whereas inhibin B and AMH levels were elevated only in patients with AGCT5. In the AUC comparison analyses, inhibin B alone was sufficient to differentiate AGCT from EOC. In differentiating AGCT from ENDO, inhibin B and AMH performed similarly, and the combination of inhibin B and AMH increased the accuracy compared to either marker alone (sensitivity, 100%; specificity, 93%). Among AGCT patients, inhibin B was the best marker for detecting the presence of AGCT. Conclusions. HE4 and CA125 levels were low in AGCTs, and inhibin B was the most accurate circulating biomarker in distinguishing AGCTs from EOCs and from ENDOs. Inhibin B was also the best single marker for AGCT follow-up. (C) 2016 Elsevier Inc. All rights reserved.Peer reviewe

Systematic drug sensitivity testing reveals synergistic growth inhibition by dasatinib or mTOR inhibitors with paclitaxel in ovarian granulosa cell tumor cells

Objective. Resistance to standard chemotherapy poses a major clinical problem in the treatment of ovarian cancer patients. Adult-type granulosa cell tumor (AGCT) is a unique ovarian cancer subtype for which efficient treatment options are lacking in advanced disease. To this end, systematic drug response and transcriptomics profiling were performed to uncover new therapy options for AGCTs. Methods. The responses of three primary and four recurrent AGCTs to 230 anticancer compounds were screened in vitro using a systematic drug sensitivity and resistance testing (DSRT) platform, coupled with mRNA sequencing. The responses of the AGCTs were compared with those of human granulosa luteal cells and bone marrow mononuclear cells. Results. Patient-derived AGCT cells showed selective sensitivity to the Src family tyrosine kinase inhibitor dasatinib. A combination of either dasatinib or an mTOR-inhibitor everolimus with paclitaxel resulted in synergistic inhibition of AGCT cell viability. The key kinase targets of dasatinib and members of the mTOR pathway were constantly expressed at mRNA and protein levels, indicating multikinase signal addictions in the AGCT cells. Transcriptomic characterization of the tumors revealed no known oncogenic mutations, suggesting that the drug sensitivity of AGCTs was rather conveyed by selective target expression. Conclusions. We used a systematic functional approach to reveal novel treatment options for a unique gynecological cancer. The selective synergy found between taxanes and dasatinib or mTOR inhibitors warrants further clinical investigations of these combinations in relapsed or aggressive AGCTs and demonstrate that high throughput drug screening and molecular profiling can provide an effective approach to uncover new therapy options.

Functional Profiling of FSH and Estradiol in Ovarian Granulosa Cell Tumors

Adult-type granulosa cell tumors (AGCTs) are sex-cord derived neoplasms with a propensity for late relapse. Hormonal modulators have been used empirically in the treatment of recurrent AGCT, albeit with limited success. To provide a more rigorous foundation for hormonal therapy in AGCT, we used a multi-modal approach to characterize the expressions of key hormone biomarkers in 175 tumor specimens and 51 serum samples using RNA sequencing, immunohistochemistry, RNA in situ hybridization, quantitative PCR, and circulating biomarker analysis, and correlated these results with clinical data. We show that FSH receptor and estrogen receptor beta (ER beta) are highly expressed in the majority of AGCTs, whereas the expressions of estrogen receptor alpha (ER alpha) and G-protein coupled estrogen receptor 1 are less prominent. ER beta protein expression is further increased in recurrent tumors. Aromatase expression levels show high variability between tumors. None of the markers examined served as prognostic biomarkers for progression-free or overall survival. In functional experiments, we assessed the effects of FSH, estradiol (E2), and the aromatase inhibitor letrozole on AGCT cell viability using 2 in vitro models: KGN cells and primary cultures of AGCT cells. FSH increased cell viability in a subset of primary AGCT cells, whereas E2 had no effect on cell viability at physiological concentrations. Letrozole suppressed E2 production in AGCTs; however, it did not impact cell viability. We did not find preclinical evidence to support the clinical use of aromatase inhibitors in AGCT treatment, and thus randomized, prospective clinical studies are needed to clarify the role of hormonal treatments in AGCTs.

Financing Forest Investments in Latin America: The Issue of Incentives

This paper discusses the topic of deforestation in Latin America and the Caribbean and the use of incentives as support for private forestry investments. The paper develops the idea of using targeted and cost-effective incentives that must take into account cultural and social factors. In addition, cost recovery mechanisms for incentive schemes should ideally be indirect, based on taxes and fees
