Differential influence of vemurafenib and dabrafenib on patient lymphocytes despite similar clinical efficacy in melanoma
2014
Background: Since the majority of melanomas eventually become resistant and progress, combining selective BRAF inhibitors (BRAFi) with immunotherapies has been proposed to achieve more durable treatment responses. Here, we explored the impact of selective BRAFi on the hosts’ immune system. Patients and methods: Clinical data, whole blood counts (WBC) and serum lactate dehydrogenase (LDH) of 277 vemurafenib- and 65 dabrafenib-treated melanoma patients were evaluated. The frequency and phenotype of lymphocyte subpopulations were determined by flow cytometry while T cell cytokine secretion was measured by multiplex assays. Results: Progression-free survival (PFS) as well as overall survival (O…
Outcome of melanoma patients with elevated LDH treated with first-line targeted therapy or PD-1-based immune checkpoint inhibition.
2020
Abstract Background Elevated lactate dehydrogenase (LDH) is a known predictive and prognostic factor for a poor outcome in patients with metastatic melanoma. It is unclear whether first-line targeted therapy (TT) or immune checkpoint inhibition (ICI) is more beneficial in melanoma patients with elevated LDH because prospective studies in this area are lacking. Methods This multicentre retrospective cohort study was conducted at 25 melanoma centres worldwide to analyse progression-free survival (PFS) and overall survival (OS) among melanoma patients with elevated LDH. The role of confounders was addressed by using inverse probability of treatment weighting. Results Among 173 BRAFV600-mutant …
The GERMELATOX DeCOG-trial : German melanoma patients and their attitude toward toxicity during adjuvant interferon treatment

Fear of progression in patients with low-risk malignant melanoma.
2017
e21615 Fear of progression in patients with low-risk malignant melanoma Fear of cancer progression (FoP) is one of the problems most commonly reported by cancer patients and is among the most prevalent cancer-related worries in cancer survivors. FCR is highly variable in different cancer entities. Background: This study aimed to elicit the prevalence and significance of FCR in melanoma patients with low risk tumors and further to assess psychosocial and demographic factors predicting severity of FoP as well as to determine the impact of FoP on quality of life (QoL). Methods: In total, 133 patients with low-risk melanoma (pT1a) completed the short version of the Fear of Progression Question…
Willingness to pay for a cure of low-risk melanoma patients in Germany
2018
Malignant melanoma is potentially life-threatening but in most cases curable if detected early. Willingness to pay (WTP) is a preference-based construct that reflects burden of disease by assessment of the monetary value for a hypothetical cure from disease. Since WTP (directly as total amount of money) has not been assessed so far in patients with low risk melanoma, it was interesting to gain insights in this patient population and then, in a second step, compare it directly with the WTP of their treating dermato-oncologists. WTP was assessed in 125 patients with low-risk melanoma and additionally in 105 treating physicians, asking for the one-time and continuous payments they would be wil…

Impact of a preceding radiotherapy on the outcome of immune checkpoint inhibition in metastatic melanoma: a multicenter retrospective cohort study of…
2020
BackgroundImmune checkpoint inhibition (ICI) is an essential treatment option in melanoma. Its outcome may be improved by a preceding radiation of metastases. This study aimed to investigate the impact of a preceding radiotherapy on the clinical outcome of ICI treatment.MethodsThis multicenter retrospective cohort study included patients who received anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) or anti-programmed cell death protein 1 (PD-1) ICI with or without preceding radiotherapy for unresectable metastatic melanoma. ICI therapy outcome was measured as best overall response (BOR), progression-free (PFS) and overall survival (OS). Response and survival analyses were adjusted …
Immune checkpoint inhibition therapy for advanced skin cancer in patients with concomitant hematological malignancy: a retrospective multicenter DeCO…
2020
BackgroundSkin cancers are known for their strong immunogenicity, which may contribute to a high treatment efficacy of immune checkpoint inhibition (ICI). However, a considerable proportion of patients with skin cancer is immuno-compromised by concomitant diseases. Due to their previous exclusion from clinical trials, the ICI treatment efficacy is poorly investigated in these patients. The present study analyzed the ICI treatment outcome in advanced patients with skin cancer with a concomitant hematological malignancy.MethodsThis retrospective multicenter study included patients who were treated with ICI for locally advanced or metastatic melanoma (MM), cutaneous squamous cell carcinoma (cS…
Discontinuation of braf/mek-directed targeted therapy after complete remission of metastatic melanoma : a retrospective multicenter adoreg study
2021
The advent of BRAF/MEK inhibitors (BRAFi/MEKi) has significantly improved progression-free (PFS) and overall survival (OS) for patients with advanced BRAF-V600-mutant melanoma. Long-term survivors have been identified particularly among patients with a complete response (CR) to BRAF/MEK-directed targeted therapy (TT). However, it remains unclear which patients who achieved a CR maintain a durable response and whether treatment cessation might be a safe option in these patients. Therefore, this study investigated the impact of treatment cessation on the clinical course of patients with a CR upon BRAF/MEK-directed-TT. We retrospectively selected patients with BRAF-V600-mutant advanced non-res…
Fear of cancer progression in patients with stage IA malignant melanoma.
2018
We aimed to determine the prevalence and importance of fear of cancer progression (FoP) in melanoma patients with stage IA tumours to assess psychosocial and demographic factors associated with severity of FoP and to determine the relationship of FoP and quality of life (QoL). One hundred and thirty-six patients with stage IA melanoma completed the short version of the Fear of Progression Questionnaire (FoP-Q-SF), the Hospital Anxiety and Depression Scale (HADS) and the EORTC-QLQ-C30. We found a mean FoP-Q-SF sum score of 30.2 points (±8.4 points SD). In this study, 33% of patients reported high FoP at or above the cutoff-value of 34 points. Higher FoP was found in women (p < 0.01), young (…
