Palliative treatment of colorectal cancer in Germany: cost of care and quality of life

Palliative Care Costs in Different Ambulatory-Based Settings: A Systematic Review

BACKGROUND

Cost-of-illness studies in palliative care are of growing interest in health economics. There is no standard methodology to capture direct and non-direct healthcare and non-healthcare expenses incurred by health services, patients and their caregivers in the course of the ambulatory palliative care process.

OBJECTIVE

We aimed to describe the type of healthcare and non-healthcare expenses incurred by patients with cancer and non-cancer patients and their caregivers for palliative care in ambulatory-based settings and the methodology used to capture the data.

METHODS

We conducted a systematic review of studies on the costs of ambulatory-based palliative care in patients with cancer (breast, lung, colorectal) and non-cancer conditions (chronic heart failure, chronic obstructive pulmonary disease, dementia) found in six bibliographic databases (PubMed, EMBASE [via Ovid], Cochrane Database of Systematic Reviews, EconLit, the National Institute for Health Research Health Technology Assessment Database and the National Health Service Economic Evaluation Database at the University of York, and Google Scholar). The studies were published between January 2000 and December 2022. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology for study selection and assessed study quality using the Quality of Health Economic Studies instrument. The study was registered in PROSPERO (CRD42021250086).

RESULTS

Of 1434 identified references, 43 articles met the inclusion criteria. The primary data source was databases. More than half of the articles presented data from public healthcare systems (65.12%) were retrospective (60.47%), and entailed a bottom-up costing analysis (93.2%) made from a healthcare system perspective (53.49%). The sociodemographic characteristics of patients and families/caregivers were similar across the studies. Cost outcomes reports were heterogeneous; almost all of the studies collected data on direct healthcare costs (97.67%). The main driver of costs was inpatient care (55.81%), which increased during the end-of-life period. Nine studies (20.97%) recorded costs due to productivity losses for caregivers and three recorded such costs for patients. Caregiving costs were explored through an opportunity cost analysis in all cases, based on interviews conducted with and questionnaires administered to patients and caregivers, mainly via telephone calls (23.23%).

CONCLUSIONS

This systematic review reveals that studies on the costs of ambulatory-based palliative care are increasing. These studies are mostly conducted from a healthcare system perspective, which leaves out costs related to patients'/caregivers' economic burden. There is a need for prospective studies to assess this financial burden and evaluate, with strong evidence, the interventions and actions designed to improve the quality of life of palliative care patients. Future studies should propose cost calculation approaches using a societal perspective to better estimate the economic burden imposed on patients in ambulatory-based palliative care.

Effectiveness of two types of palliative home care in cancer and non-cancer patients: A retrospective population-based study using claims data

BACKGROUND

Comparative effectiveness of different types of palliative homecare is sparsely researched internationally-despite its potential to inform necessary decisions in palliative care infrastructure development. In Germany, specialized palliative homecare delivered by multi-professional teams has increased in recent years and factors beyond medical need seem to drive its involvement and affect the application of primary palliative care, delivered by general practitioners who are supported by nursing services.

AIM

To compare effectiveness of primary palliative care and specialized palliative homecare in reducing potentially aggressive interventions at the end-of-life in cancer and non-cancer.

DESIGN

Retrospective population-based study with claims data from 95,962 deceased adults in Germany in 2016 using multivariable regression analyses.

SETTINGS/PARTICIPANTS

Patients having received primary palliative care or specialized palliative homecare (alone or in addition to primary palliative care), for at least 14 days before death, differentiating between cancer and non-cancer patients.

RESULTS

Rates of potentially aggressive interventions in most indicators were higher in primary palliative care than in specialized palliative homecare (p < 0.01), in both cancer and non-cancer patients: death in hospital (odds ratio (OR) 4.541), hospital care (OR 2.720), intensive care treatment (OR 6.749), chemotherapy (OR 2.173), and application of a percutaneous endoscopic gastrostomy (OR 4.476), but not for parenteral nutrition (OR 0.477).

CONCLUSION

Specialized palliative homecare is more strongly associated with reduction of potentially aggressive interventions than primary palliative care in the last days of life. Future research should identify elements of specialized palliative homecare applicable for more effective primary palliative care, too. German Clinical Trials Register (DRKS00014730).

Application study of the EQ-5D-5L in oncology: linking self-reported quality of life of patients with advanced or metastatic colorectal cancer to clinical data from a German tumor registry

BACKGROUND

The EQ-5D-5L questionnaire is used in oncology to generate health-related quality of life (HRQoL) weights and corresponding health states. The purpose was to explore the relationship between demographic and clinical characteristics and HRQoL among advanced or metastatic colorectal cancer (CRC) patients by linking clinical data of a German CRC registry to self-reported HRQoL measures from the EQ-5D-5L.

METHODS

The study sample included patients with advanced or metastatic CRC currently recruited in the German Tumor Registry Colorectal Cancer. The EQ-5D-5L was administered once to patients who were at the start or at later stages of palliative treatment. Data on comorbidities, disease-specific health states, symptoms, and treatment status were drawn from the registry. Multivariate regression analyses were performed to explore the impact of patient and disease characteristics on HRQoL.

RESULTS

In total, n = 433 questionnaires were included in the data analysis. Mean age of patients was 66.3 years and 61.2% were male. The mean EQ-5D-5L utility score was 0.82 and the mean EQ-5D-5L VAS score was 62.05. The regression analyses revealed that none of the demographic characteristics and few of the clinical characteristics, such as fatigue and pain, had a significant impact on the HRQoL.

CONCLUSIONS

The study demonstrated a reduced HRQoL of patients with advanced or metastatic CRC when compared to the general population. The symptoms fatigue and pain negatively affected the HRQoL, whereas other characteristics such as age, gender, and comorbidities did not have a significant impact on HRQoL.

Management and intensity of medical end-of-life care in people with colorectal cancer during the year before their death in 2015: A French national observational study

The care pathway of patients with colorectal cancer (CRC) 1 year prior to death, their causes of death and the healthcare use, and associated expenditure remain poorly described together. People managed for CRC (2014‐2015), covered by the national health insurance general scheme and who died in 2015 were selected from the national health data system. A total of 15 361 individuals (mean age: 75 years, SD: 12.5 years) were included, almost 66% of whom died in short‐stay hospital (SSH), 9% in hospital at home (HaH), 4% in rehabilitation units (Rehab), 6% in skilled nursing homes (SNH), and 15% at home. At least one other cancer was identified for one‐third of these people. Almost one‐half of people presented cardiovascular comorbidity, 21% had chronic respiratory disease, and 13% had a neurological or degenerative disease. During the last month of life, 83% were admitted at least once to SSH, 39% had at least one emergency department admission, 17% were admitted to an intensive care unit, 15% received at least one chemotherapy session (<60 years: 27%), and 5% received oral chemotherapy. Eighty‐eight percent of the 60% of individuals who received hospital palliative care (HPC) vs 75% of those without HPC were admitted to SSH at least once during the last month. Cancer was the main cause of death for 84% (SSH: 85%, home: 77%) and corresponded to CRC for 64% of them. The mean annual expenditure per person during the last year of life was €43 398 (SSH: €48 804). This study suggests a relatively high level of HPC use during the year before death for people with CRC in France. High rates of emergency department, intensive care, and chemotherapy use were observed during the last month of life. However, management is very largely SSH‐based with a small proportion of deaths at home.

Cost-Effectiveness Analysis of Total Neoadjuvant Therapy Followed by Radical Resection Versus Conventional Therapy for Locally Advanced Rectal Cancer

BACKGROUND

Definitive surgery with total mesorectal excision is the mainstay of treatment for locally advanced rectal cancer. Multimodality therapy improves long-term survival. Current standards advise neoadjuvant chemoradiation followed by radical surgery and adjuvant chemotherapy. Nationally, compliance with adjuvant chemotherapy is only 32%. New research evaluates the effectiveness of total neoadjuvant therapy: complete chemotherapy and chemoradiation before surgery.

OBJECTIVE

The aim of this study is to determine the favored treatment for locally advanced rectal cancer by comparing the cost-effectiveness of total neoadjuvant therapy and the current standard of care.

DESIGN

Decision analytical modeling using long-term costs and 5-year disease-free survival was performed to determine the cost-effectiveness after total neoadjuvant therapy and the current standard of care. Sensitivity analysis was used to investigate the effect of uncertainty in model parameters.

SETTINGS

Centers for Medicare & Medicaid Services billing data perspective was adopted and outcomes modeled according to local and national databases and literature consensus.

PATIENTS

Adult patients with stage II or III rectal cancer were selected.

MAIN OUTCOME MEASURES

Cost-effectiveness in disease-free life-years, incremental cost-effectiveness ratio, and net monetary benefit were determined over a 5-year posttreatment period. The favored strategy was determined based on cost-effectiveness and sensitivity analyses.

RESULTS

Cost-effectiveness for total neoadjuvant therapy was 40,708 $/life-year, and, for conventional therapy, cost-effectiveness was 44,248 $/life-year. Sensitivity analysis showed that, for an estimated total neoadjuvant therapy completion rate of 90%, total neoadjuvant therapy would remain the dominant strategy for any adjuvant chemotherapy completion rate of less than 93%.

LIMITATIONS

The samples used to calculate completion rates are small, and survival probabilities are based on existing literature, local database values, and consensus estimates. The model encompasses a 5-year time period from diagnosis.

CONCLUSIONS

Cost-effectiveness analysis shows that a strategy of total neoadjuvant therapy followed by radical surgery is favored over the current standard of care for locally advanced rectal cancer. Sensitivity analysis shows that a low rate of adjuvant chemotherapy administration plays a key role in decreasing the cost-effectiveness of the current standard of care.

Cost-effectiveness of immune checkpoint inhibitors for microsatellite instability-high/mismatch repair-deficient metastatic colorectal cancer

BACKGROUND

Patients with microsatellite instability-high (MSI-H)/mismatch repair-deficient (dMMR) metastatic colorectal cancer (mCRC) show a significant response to checkpoint inhibitor therapies, but the economic impact of these therapies is unknown. A decision analytic model was used to explore the effectiveness and cost burden of MSI-H/dMMR mCRC treatment.

METHODS

The treatment of hypothetical patients with MSI-H/dMMR mCRC was simulated in 2 treatment scenarios: a third-line treatment and an exploratory first-line treatment. The treatments compared were nivolumab, ipilimumab and nivolumab, trifluridine and tipiracil (third-line treatment), and mFOLFOX6 and cetuximab (first-line treatment). Disease progression, drug toxicity, and survival rates were based on the CheckMate 142, study of TAS-102 in patients with metastatic colorectal cancer refractory to standard chemotherapies (RECOURSE), and Cancer and Leukemia Group B/Southwest Oncology Group 80405 trials. The analyzed outcomes included survival (life-years), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs).

RESULTS

Ipilimumab with nivolumab was the most effective strategy (10.69 life-years and 9.25 QALYs for the third line; 10.69 life-years and 9.44 QALYs for the first line) in comparison with nivolumab (8.21 life-years and 6.76 QALYs for the third line; 8.21 life-years and 7.00 QALYs for the first line), trifluridine and tipiracil (0.74 life-years and 0.07 QALYs), and mFOLFOX6 and cetuximab (2.72 life-years and 1.63 QALYs). However, neither checkpoint inhibitor therapy was cost-effective in comparison with trifluridine and tipiracil (nivolumab ICER, $153,000; ipilimumab and nivolumab ICER, $162,700) or mFOLFOX6 and cetuximab (nivolumab ICER, $150,700; ipilimumab and nivolumab ICER, $158,700).

CONCLUSIONS

This modeling analysis found that both single and dual checkpoint blockade could be significantly more effective for MSI-H/dMMR mCRC than chemotherapy, but they were not cost-effective, largely because of drug costs. Decreases in drug pricing and/or the duration of maintenance nivolumab could make ipilimumab and nivolumab cost-effective. Prospective clinical trials should be performed to explore the optimal duration of maintenance nivolumab.

Targeted nanoparticles for colorectal cancer

Colorectal cancer (CRC) is highly prevalent worldwide, and despite notable progress in treatment still leads to significant morbidity and mortality. The use of nanoparticles as a drug delivery system has become one of the most promising strategies for cancer therapy. Targeted nanoparticles could take advantage of differentially expressed molecules on the surface of tumor cells, providing effective release of cytotoxic drugs. Several efforts have recently reported the use of diverse molecules as ligands on the surface of nanoparticles to interact with the tumor cells, enabling the effective delivery of antitumor agents. Here, we present recent advances in targeted nanoparticles against CRC and discuss the promising use of ligands and cellular targets in potential strategies for the treatment of CRCs.

Financial burden of colorectal cancer treatment among patients and their families in a middle-income country

BACKGROUND

In Malaysia, the healthcare system consists of a government-run universal healthcare system and a co-existing private healthcare system. However, with high and ever rising healthcare spending on cancer management, cancer patients and their families are likely to become vulnerable to a healthcare-related financial burden. Moreover, they may have to reduce their working hours and lose income. To better understand this issue, this study aims to assess the financial burden of colorectal cancer patients and their families in the first year following diagnosis.

METHODS

Data on patient costs were collected prospectively in the first year following diagnosis by using a self-administered questionnaire and telephone interviews at three time points for all four stages of colorectal cancer. The patient cost data consisted of direct out-of-pocket payments for medical-related expenses such as hospital stays, tests and treatment and for non-medical items such as travel and food associated with hospital visits. In addition, indirect cost data related to the loss of productivity of the patient and caregiver(s) was assessed. The patient's perceived level of financial difficulty and types of coping strategy were also explored.

RESULT

The total 1-year patient cost (both direct and indirect) increased with the stage of colorectal cancer: RM 6544.5 (USD 2045.1) for stage I, RM 7790.1 (USD 2434.4) for stage II, RM 8799.1 (USD 2749.7) for stage III and RM 8638.2 (USD 2699.4) for stage IV. The majority of patients perceived paying for their healthcare as somewhat difficult. The most frequently used financial coping strategy was a combination of current income and savings.

CONCLUSION

Despite the high subsidisation in public hospitals, the management of colorectal cancer imposes a substantial financial burden on patients and their families. Moreover, the majority of patients and their families perceive healthcare payments as difficult. Therefore, it is recommended that policy- and decision-makers should further consider some financial protection strategies and support for cancer treatment because cancer is a very costly and chronic disease.

Antiemetic prophylaxis and frequency of chemotherapy-induced nausea and vomiting in palliative first-line treatment of colorectal cancer patients: the Northern Bavarian IVOPAK I Project

PURPOSE

This study aims to evaluate adherence to guidelines of antiemetic prophylaxis and frequency of chemotherapy-induced nausea and vomiting (CINV) in the palliative first-line treatment of colorectal cancer (CRC) patients in Northern Bavaria.

METHODS

We collected detailed information on chemotherapy and supportive drugs in 103 patients within a prospective observational study. The study was conducted to determine quality of care within an interdisciplinary context (first endpoint) and direct costs of palliative treatment for patients with CRC between 2006 and 2010 (second endpoint, Emmert et al. (Eur J Health Econ, 2012) [1]). In this paper, we evaluate adherence to Multinational Association of Supportive Care in Cancer (MASCC) 2006 recommendations for prophylaxis of CINV during the first administration of chemotherapy as well as incidence and grade of CINV within 120 h thereafter.

RESULTS

Of the patients studied, 95 patients (92%) received moderately emetogenic (oxaliplatin- and/or irinotecan-containing combined chemotherapy treatment) and eight (8%) received low emetogenic chemotherapy (either 5-fluorouracil (5-FU) or capecitabine monotherapy). Antiemetic prophylaxis could be assessed in 101 out of 103 (98%) of patients. MASCC-recommended antiemetic prophylaxis was prescribed in three patients (3%). Nonadherence was mainly caused by omission of dexamethasone. Nausea and/or vomiting occurred in 18 patients (18%) within a 120-h period. All documented episodes were grade 1 or 2 according to the Common Toxicity Criteria of the National Cancer Institute. None of these patients received the recommended prophylaxis for CINV. In only one patient, antiemetic prophylaxis was intensified during the next chemotherapy application.

CONCLUSIONS

In the Integrated Health Care in the Palliative Treatment of Colorectal Carcinoma (IVOPAK) I Project, adherence to the MASCC clinical recommendations was very poor. Extent of CINV in this patient population seems to be underestimated. There is an urgent need to improve clinicians' awareness of this patient-relevant side effect.
