Economic Evaluation of a Tumour-Agnostic Therapy: Dutch Economic Value of Larotrectinib in TRK Fusion-Positive Cancers.

BACKGROUND: Larotrectinib is the first tumour-agnostic therapy that has been approved by the European Medicines Agency. Tumour-agnostic therapies are indicated for a multitude of tumour types. The economic models supporting reimbursement submissions of tumour-agnostic therapies are complex because of the multitude of indications per model. OBJECTIVE: The objective of this paper was to evaluate the cost effectiveness of larotrectinib compared with standard of care in patients with cancer with tropomyosin receptor kinase fusion-positive tumour types in the Netherlands. METHODS: A previously constructed cost-effectiveness model with a partitioned survival approach was adapted to the Dutch setting, simulating costs and effects of treatment in patients with tropomyosin receptor kinase fusion-positive cancer. The cost-effectiveness model conducts a naïve comparison of larotrectinib to a weighted comparator standard-of-care arm. Dutch specific resource use and costs were implemented and inflated to reflect 2019 euros. The analysis includes a lifetime horizon and a societal perspective. RESULTS: Larotrectinib versus Dutch standard of care resulted in 5.61 incremental (QALYs) and €232,260 incremental costs, leading to an incremental cost-effectivenes ratio of €41,424/QALY. The probabilistic sensitivity analysis reveals a 88% chance of larotrectinib being cost effective compared with the pooled comparator standard-of-care arm at the applicable €80,000/QALY willingness-to-pay threshold in the Netherlands. CONCLUSIONS: The incremental cost-effectivenes ratio was well below the applicable threshold for diseases with a high burden of disease in the Netherlands (€80,000). At this threshold, larotrectinib was estimated to be a cost-effective treatment for patients with tropomyosin receptor kinase fusion-positive cancer compared with current standard of care in the Netherlands.

Unmet supportive care needs of patients with rare cancer: A systematic review.

OBJECTIVE: Patients with rare cancers may experience different unmet needs than those with common cancer. The objective of this systematic review was to (1) investigate unmet supportive care needs of rare cancer patients throughout the disease trajectory and (2) identify predictive factors for these unmet needs. METHODS: PubMed, PsycINFO and CINAHL were searched for publications (January 2011 to March 2021) focusing on unmet needs of patients with rare cancer. Two reviewers independently selected studies, extracted data and performed quality assessment. Findings were synthesised. RESULTS: The search yielded 4,598 articles, of which 59 articles met eligibility criteria and 57 were of medium or high quality. Rare cancer patients most frequently reported unmet needs in the healthcare system and information domain (up to 95%), followed by the psychological domain (up to 93%) and the physical and daily living domain (up to 80%). Unmet needs were mainly reported in the posttreatment phase. The most frequently identified predictors were higher anxiety, younger age and higher neuroticism. CONCLUSION: Patients with rare cancer have unmet needs throughout their disease trajectory. Supportive care needs of rare cancer patients should be addressed individually, depending on the rare cancer subdomain and phase of disease and from diagnosis onwards.

Prophylactic antibiotics reduce hospitalisations and cost in locally advanced head and neck cancer patients treated with chemoradiotherapy: A randomised phase 2 study.

BACKGROUND: Platinum-based chemoradiotherapy for locally advanced head and neck cancer (LAHNC) induces a high rate of acute toxicity, including dysphagia and aspiration pneumonia. We hypothesised that prophylactic antibiotics can prevent pneumonia and hospitalisations and can be cost-effective. PATIENT AND METHODS: In this multicentre randomised trial, patients with LAHNC treated with chemoradiotherapy received prophylactic amoxicillin/clavulanic acid from day 29 after the start of treatment until 14 days after completion of chemoradiotherapy or standard care without prophylaxis. The primary objective was to observe a reduction in pneumonias. Secondary objectives were to evaluate the hospitalisation rate, adverse events, costs and health-related quality of life. RESULTS: One hundred six patients were included; of which, 95 were randomised: 48 patients were allocated to the standard group and 47 patients to the prophylaxis group. A pneumonia during chemoradiotherapy and follow-up until 3.5 months was observed in 22 (45.8%) of 48 patients in the standard group and in 22 (46.8%) of 47 patients in the prophylaxis group (p = 0.54). Hospitalisation rate was significantly higher in the standard group versus the prophylaxis group, 19 of 48 pts (39.6%) versus 9 of 47 pts (19.1%), respectively (p = 0.03). Significantly more episodes with fever of any grade were observed in the standard group (29.2% vs 10.2%, p = 0.028). A significant difference in costs was found, with an average reduction of €1425 per patient in favour of the prophylaxis group. CONCLUSION: Although prophylactic antibiotics during chemoradiotherapy for patients with LAHNC did not reduce the incidence of pneumonias, it did reduce hospitalisation rates and episodes with fever significantly and consequently tended to be cost-effective.

Positron emission tomography response criteria in solid tumours criteria for quantitative analysis of [18F]-fluorodeoxyglucose positron emission tomography with integrated computed tomography for treatment response assessment in metastasised solid tumours: All that glitters is not gold.

For solid tumours, quantitative analysis of [(18)F]-fluorodeoxyglucose positron emission tomography with integrated computed tomography potentially can have significant value in early response assessment and thereby discrimination between responders and non-responders at an early stage of treatment. Standardised strategies for this analysis have been proposed, and the positron emission tomography response criteria in solid tumours (PERCIST) criteria can be regarded as the current standard to perform quantitative analysis in a research setting, yet is not implemented in daily practice. However, several exceptions and limitations limit the feasibility of PERCIST criteria. In this article, we point out dilemmas that arise when applying proposed criteria like PERCIST on an expansive set of patients with metastasised solid tumours. Clinicians and scientists should be aware of these limitations to prevent that methodological issues impede successful introduction of research data into clinical practice. Therefore, to deliver on the high potential of quantitative imaging, consensus should be reached on a standardised, feasible and clinically useful analysis methodology. This methodology should be applicable in the majority of patients, tumour types and treatments.

Treatments and costs for recurrent and/or metastatic squamous cell carcinoma of the head and neck in the Netherlands.

For patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN), chemotherapy can prolong life and alleviate symptoms. However, expected gains may be small, not necessarily outweighing considerable toxicity and high costs. Treatment choice is to a large extent dependent on preferences of doctors and patients and data on these choices are scarce. The purpose of this study is to obtain real-world information on palliative systemic treatment and costs of R/M SCCHN in the Netherlands. In six Dutch head and neck treatment centers, data were collected on patient and tumor characteristics, treatment patterns, disease progression, survival, adverse events, and resource use for R/M SCCHN, between 2006 and 2013. 125 (14 %) out of 893 R/M SCCHN patients received palliative, non-trial first-line systemic treatment, mainly platinum + 5FU + cetuximab (32 %), other platinum-based combination therapy (13 %), methotrexate monotherapy (27 %) and capecitabine monotherapy (14 %). Median progression-free survival and overall survival were 3.4 and 6.0 months, respectively. 34 (27 %) patients experienced severe adverse events. Mean total hospital costs ranged from € 10,075 (± € 9,891) (methotrexate monotherapy) to € 39,459 (± € 21,149) (platinum + 5FU + cetuximab). Primary cost drivers were hospital stays and anticancer drug treatments. Major health care utilization and costs are involved in systemically treating R/M SCCHN patients with a limited survival.

Long-term outcome and morbidity after treatment with accelerated radiotherapy and weekly cisplatin for locally advanced head-and-neck cancer: results of a multidisciplinary late morbidity clinic.

PURPOSE: To evaluate the long-term outcome and morbidity after intensified treatment for locally advanced head-and-neck cancer. METHODS AND MATERIALS: Between May 2003 and December 2007, 77 patients with Stage III to IV head-and-neck cancer were treated with curative intent. Treatment consisted of accelerated radiotherapy to a dose of 68 Gy and concurrent cisplatin. Long-term survivors were invited to a multidisciplinary outpatient clinic for a comprehensive assessment of late morbidity with special emphasis on dysphagia, including radiological evaluation of swallowing function in all patients. RESULTS: Compliance with the treatment protocol was high, with 87% of the patients receiving at least five cycles of cisplatin and all but 1 patient completing the radiotherapy as planned. The 5-year actuarial disease-free survival and overall survival rates were 40% and 47%, respectively. Locoregional recurrence-free survival at 5 years was 61%. The 5-year actuarial rates of overall late Radiation Therapy Oncology Group (RTOG)/European Organization for Research and Treatment of Cancer (EORTC) Grade 3 and Grade 4 toxicity were 52% and 25% respectively. Radiologic evaluation after a median follow-up of 44 months demonstrated impaired swallowing in 57% of the patients, including 23% with silent aspiration. Subjective assessment using a systematic scoring system indicated normalcy of diet in only 15.6% of the patients. CONCLUSION: This regimen of accelerated radiotherapy with weekly cisplatin produced favorable tumor control rates and survival rates while compliance was high. However, comprehensive assessment by a multidisciplinary team of medical and paramedical specialists revealed significant long-term morbidity in the majority of the patients, with dysphagia being a major concern.

PET-CT for response assessment and treatment adaptation in head and neck cancer.

Preferred treatment strategies for advanced-stage squamous cell carcinoma of the head and neck have shifted from surgery to organ-preservation approaches such as radiotherapy, which can be combined with chemotherapy or giving of biologically modifying molecules. Preclinical and clinical researchers aim to customise these treatments on the basis of biological tumour characteristics, including tumour cell proliferation, hypoxia, and apoptosis--important resistance mechanisms for cytotoxic antitumour therapy. Monitoring of these biologically relevant variables before and early during treatment could improve patient selection for specific treatment strategies and guide adaptation of treatment at an early stage. PET provides a non-invasive molecular imaging method with the potential ability to undertake repetitive non-invasive quantification of relevant tumour characteristics. We discuss the role of PET scanning and available radiopharmaceutical tracers for treatment selection, early response monitoring, and treatment adaptation in head and neck cancer.
