Exploring supportive care and information needs through a proposed eHealth application among melanoma patients undergoing systemic therapy: a qualitative study

BACKGROUND: During and after systemic therapy, patients with high risk and advanced melanoma experience challenges regarding cancer-related symptoms, treatment-related adverse events, and an impact of these symptoms on their physical and psychosocial well-being. Few studies have investigated the specific needs of these patients and the potential role of eHealth applications in meeting those needs. OBJECTIVE: To explore the supportive care and information needs of high risk and advanced melanoma patients, and how these needs can be supported by eHealth applications. METHODS: In this qualitative study, semi-structured interviews with high risk and advanced melanoma patients during or after systemic treatment were conducted to understand their needs and requirements as possible end-users of mobile eHealth applications. Interview transcripts were independently coded and thematically analyzed. RESULTS: Thirteen participants consented to be interviewed, aged 31 to 71 years. Nearly all patients (n = 12, 92%) experienced unmet information and supportive care needs during and after active treatment. Patients expected to value eHealth applications that facilitate information gathering, wellbeing interventions, and symptom management. The majority of patients (n = 10, 77%) anticipated various advantages from using an eHealth application, including increased autonomy, higher quality of life, and improved disease self-management. DISCUSSION: High risk and advanced melanoma patients have unmet supportive care and information needs during and after systemic treatment. The use of eHealth applications might be an effective way to meet these unmet needs. Patients anticipate a variety of advantages from using these applications, including deriving various benefits from the use of these applications, such as enhanced autonomy

Tumor infiltrating lymphocytes (TIL) therapy in metastatic melanoma: boosting of neoantigen-specific T cell reactivity and long-term follow-up

Purpose Execute a phase I/II feasibility study with TIL therapy in metastatic melanoma at the Netherlands Cancer Institute, with the goal to assess feasibility and potential value of a randomized phase III trial.Experimental Ten patients were treated with TIL therapy. Infusion products and peripheral blood samples were phenotypically characterized and neoantigen reactivity was assessed. Here, we present long-term clinical outcome and translational data on neoantigen reactivity of the T cell products.Results Five out of 10 patients, who were all anti-PD-1 naïve at time of treatment, showed an objective clinical response, including two patients with a complete response that are both ongoing for more than 7 years. Immune monitoring demonstrated that neoantigen-specific T cells were detectable in TIL infusion products from three out of three patients analyzed. For six out of the nine neoantigen-specific T cell responses detected in these TIL products, T cell response magnitude increased significantly in the peripheral blood compartment after therapy, and neoantigen-specific T cells were detectable for up to 3 years after TIL infusion.Conclusion The clinical results from this study confirm the robustness of TIL therapy in metastatic melanoma and the potential role of neoantigen-specific T cell reactivity. In addition, the data from this study supported the rationale to initiate an ongoing multicenter phase III TIL trial

T-cell immune function in tumor, skin, and peripheral blood of advanced stage melanoma patients: implications for immunotherapy

To predict the potential antitumor effect of antigen-specific T cells in melanoma patients, we investigated T-cell effector function in relation to tumor-escape mechanisms. CD8(+) T cells isolated from tumor, adjacent normal skin, and peripheral blood of 17 HLA-A2(+) patients with advanced-stage melanoma were analyzed for their antigen specificity and effector function against melanocyte differentiation antigens MART-1, gp100, and tyrosinase by using HLA-A2/peptide tetramers and functional assays. In addition, the presence of tumor-escape mechanisms PD-L1/PD-1 pathway, FoxP3 and loss of HLA or melanocyte differentiation antigens, both required for tumor cell recognition and killing, were studied. Higher percentages of melanocyte antigen-specific CD8(+) T cells were found in the melanoma tissues as compared with adjacent normal skin and peripheral blood. Functional analysis revealed 2 important findings: (i) in 5 of 17 patients, we found cytokine production after specific peptide stimulation by tumor-infiltrating lymphocytes (TIL), not by autologous peripheral blood lymphocytes (PBL); (ii) CD8(+) T cells from 7 of 17 patients did not produce cytokines after specific stimulation, which corresponded with significant loss of tumor HLA-A2 expression. The presence of other tumor-escape mechanisms did not correlate to T-cell function. Our data show that functional T-cell responses could be missed when only PBL and not TIL are evaluated, emphasizing the importance of TIL analysis for immunomonitoring. Furthermore, loss of tumor HLA-A2 may explain the lack of T-cell functionality. These findings have important implications for selecting melanoma patients who may benefit from immunotherap

An eHealth App (CAPABLE) Providing Symptom Monitoring, Well-Being Interventions, and Educational Material for Patients With Melanoma Treated With Immune Checkpoint Inhibitors: Protocol for an Exploratory Intervention Trial

BackgroundSince treatment with immune checkpoint inhibitors (ICIs) is becoming standard therapy for patients with high-risk and advanced melanoma, an increasing number of patients experience treatment-related adverse events such as fatigue. Until now, studies have demonstrated the benefits of using eHealth tools to provide either symptom monitoring or interventions to reduce treatment-related symptoms such as fatigue. However, an eHealth tool that facilitates the combination of both symptom monitoring and symptom management in patients with melanoma treated with ICIs is still needed. ObjectiveIn this pilot study, we will explore the use of the CAPABLE (Cancer Patients Better Life Experience) app in providing symptom monitoring, education, and well-being interventions on health-related quality of life (HRQoL) outcomes such as fatigue and physical functioning, as well as patients’ acceptance and usability of using CAPABLE. MethodsThis prospective, exploratory pilot study will examine changes in fatigue over time in 36 patients with stage III or IV melanoma during treatment with ICI using CAPABLE (a smartphone app and multisensory smartwatch). This cohort will be compared to a prospectively collected cohort of patients with melanoma treated with standard ICI therapy. CAPABLE will be used for a minimum of 3 and a maximum of 6 months. The primary endpoint in this study is the change in fatigue between baseline and 3 and 6 months after the start of treatment. Secondary end points include HRQoL outcomes, usability, and feasibility parameters. ResultsStudy inclusion started in April 2023 and is currently ongoing. ConclusionsThis pilot study will explore the effect, usability, and feasibility of CAPABLE in patients with melanoma during treatment with ICI. Adding the CAPABLE system to active treatment is hypothesized to decrease fatigue in patients with high-risk and advanced melanoma during treatment with ICIs compared to a control group receiving standard care. The Medical Ethics Committee NedMec (Amsterdam, The Netherlands) granted ethical approval for this study (reference number 22-981/NL81970.000.22).

Tumor infiltrating lymphocytes (TIL) therapy in metastatic melanoma: boosting of neoantigen-specific T cell reactivity and long-term follow-up

Treatment of metastatic melanoma with autologous tumor infiltrating lymphocytes (TILs) is currently applied in several centers. Robust and remarkably consistent overall response rates, of around 50% of treated patients, have been observed across hospitals, including a substantial fraction of durable, complete responses. PURPOSE: Execute a phase I/II feasibility study with TIL therapy in metastatic melanoma at the Netherlands Cancer Institute, with the goal to assess feasibility and potential value of a randomized phase III trial. EXPERIMENTAL: Ten patients were treated with TIL therapy. Infusion products and peripheral blood samples were phenotypically characterized and neoantigen reactivity was assessed. Here, we present long-term clinical outcome and translational data on neoantigen reactivity of the T cell products. RESULTS: Five out of 10 patients, who were all anti-PD-1 naïve at time of treatment, showed an objective clinical response, including two patients with a complete response that are both ongoing for more than 7 years. Immune monitoring demonstrated that neoantigen-specific T cells were detectable in TIL infusion products from three out of three patients analyzed. For six out of the nine neoantigen-specific T cell responses detected in these TIL products, T cell response magnitude increased significantly in the peripheral blood compartment after therapy, and neoantigen-specific T cells were detectable for up to 3 years after TIL infusion. CONCLUSION: The clinical results from this study confirm the robustness of TIL therapy in metastatic melanoma and the potential role of neoantigen-specific T cell reactivity.

The effect of seasonal variation and secretion of sunitinib in sweat on the development of hand-foot syndrome

Item does not contain fulltextBACKGROUND: Hand-foot syndrome (HFS) is a side effect of sunitinib with considerable impact on quality of life. Seasonal variation and hyperhydrosis are possibly correlated to occurrence of HFS. Therefore, we proposed to study the prevalence of HFS in different seasons retrospectively and to study the relationship between sunitinib sweat secretion and HFS prospectively. PATIENTS AND METHODS: A retrospective cohort of 19 patients treated with sunitinib was used to determine seasonal prevalence of HFS. In a prospective study, sunitinib and N-desethyl sunitinib levels in sweat patches of 25 patients treated with sunitinib were quantified and correlated to severity of HFS. RESULTS: In the retrospective cohort, the patients suffered from more severe HFS during summertime compared with the rest of the year. In the prospective study, the cumulative amounts of sunitinib plus metabolite measured in the patches of the on-treatment phase (median 129.4 ng/patch) were higher than the off-treatment phase (median 39.5 ng/patch). A tendency was observed towards increasing amounts of drug per patch with increasing severity of HFS. CONCLUSION: Patients experienced more HFS in summer time compared to other seasons. However, no statistically significant correlation between sunitinib sweat secretion and severity of HFS could be demonstrated within our patient cohort
