Intermittent High-Dose Intravenous Interferon Alfa-2b for Adjuvant Treatment of Stage III Melanoma: Final Analysis of a Randomized Phase III Dermatologic Cooperative Oncology Group Trial

Systemic Therapy for Melanoma: ASCO Guideline Update

PURPOSE

To provide guidance to clinicians regarding the use of systemic therapy for melanoma.

METHODS

American Society of Clinical Oncology convened an Expert Panel and conducted an updated systematic review of the literature.

RESULTS

The updated review identified 21 additional randomized trials.

UPDATED RECOMMENDATIONS

Neoadjuvant pembrolizumab was newly recommended for patients with resectable stage IIIB to IV cutaneous melanoma. For patients with resected cutaneous melanoma, adjuvant nivolumab or pembrolizumab was newly recommended for stage IIB-C disease and adjuvant nivolumab plus ipilimumab was added as a potential option for stage IV disease. For patients with unresectable or metastatic cutaneous melanoma, nivolumab plus relatlimab was added as a potential option regardless of BRAF mutation status and nivolumab plus ipilimumab followed by nivolumab was preferred over BRAF/MEK inhibitor therapy. Talimogene laherparepvec is no longer recommended as an option for patients with BRAF wild-type disease who have progressed on anti-PD-1 therapy. Ipilimumab- and ipilimumab-containing regimens are no longer recommended for patients with BRAF-mutated disease after progression on other therapies.This full update incorporates the new recommendations for uveal melanoma published in the 2022 Rapid Recommendation Update.Additional information is available at www.asco.org/melanoma-guidelines.

A systematic review of patient-reported outcome measures for advanced skin cancer patients

Many patient-reported outcome measures (PROMs) have been used to study quality of life (QOL) in the skin cancer population. Advanced melanoma and non-melanoma skin cancer (NMSC) may be associated with increased morbidity, mortality, and treatment side effects; however, it is unclear which PROM is valid and appropriate to use in these populations for both clinical and research purposes. We aimed to identify the PROMs that have been used to measure QOL in advanced skin cancer patients and determine which of these PROMs have been validated to assess QOL outcomes in this population. A PubMed and EMBASE search was conducted from its inception to March 2021 according to PRISMA guidelines with a comprehensive list of search terms under three main topics: (1) PROM; (2) advanced skin cancer; and (3) staging and interventions. We included articles utilizing a PROM measuring QOL and having a patient population with advanced skin cancer defined as melanoma stage > T1a or non-melanoma AJCC stage T3 or greater. Advanced skin cancer patients were also defined as those with metastasis or requiring adjuvant therapy (systemic chemotherapy, radiation, and immunotherapy). Studies were excluded according to the following criteria: mix of low-risk and advanced skin cancer patients in the study population without stratification into low-risk and advanced groups, stage T1a melanoma or mix of stages without stratification, low-risk NMSC, no PROM (i.e., study specific questionnaires), non-English publication, review article or protocol paper, conference abstract, or populations including non-skin cancers. A total of 1,998 articles were identified. 82 met our inclusion criteria resulting in 22 PROMs: five generic health-related (QWB-SA, AQoL-8D, EQ-5D, SF-36, and PRISM), six general cancer (EORTC QLQ-C30, EORTC QLQ-C36, LASA, IOC, Rotterdam Symptom Checklist, and FACT-G), nine disease-focused or specialized (EORTC QLQ-H&N35, EORTC QLQ-MEL38, EORTC QLQ-BR23, Facial Disability Index, FACT-H&N, FACT-BRM, FACT-B, FACT-M, and scqolit), and two general dermatology (Skindex-16 and DLQI) PROMs. All PROMs have been generally validated except for EORTC QLQ-MEL38. Only two PROMs have been validated in the advanced melanoma population: FACT-M and EORTC QLQ-C36. No PROMS have been validated in the advanced NMSC population. The PROMs that were validated in the advanced melanoma population do not include QOL issues unique to advanced skin tumors such as odor, bleeding, itching, wound care burden, and public embarrassment. Breast cancer and head and neck cancer instruments were adapted but not validated for use in the advanced skin cancer population due to the lack of an adequate instrument for this population. This study highlights the need for PROM instrument validation or creation specifically geared toward the advanced skin cancer population. Future studies should aim to develop and validate a PROM to assess QOL in this population.

Comparison of efficacy and tolerability of adjuvant therapy for resected high-risk stage III-IV cutaneous melanoma: a systemic review and Bayesian network meta-analysis

Background

Although immune checkpoint inhibitors (ICIs) and targeted therapies have been widely used as adjuvant treatment for resected melanoma, the optimal therapy remains controversial. Therefore, we conducted this updated network meta-analysis (NMA) to assess the efficacy and tolerability of adjuvant therapies for cutaneous melanoma.

Methods

PubMed, Embase, Cochrane library, and Web of Science were systematically searched for relevant literatures published in the last 30 years. Disease-free survival (DFS), overall survival (OS), and serious adverse events were considered as the efficacy and tolerability outcomes.

Results

In all, 27 randomized controlled trials (RCTs) including 16,709 stage III-IV melanoma patients were enrolled in this NMA. For BRAF wild-type melanoma, our analysis showed that both nivolumab and pembrolizumab demonstrated significantly better DFS and tolerability than ipilimumab (10 mg/kg). Nivolumab, pembrolizumab, ipilimumab (3 mg/kg), and ipilimumab (10 mg/kg) all appeared to be effective in prolonging OS, but no therapy demonstrated significantly better OS than ipilimumab (10 mg/kg). Nivolumab + ipilimumab showed the best DFS, but did not appear to be effective in improving OS and ranked only seventh in tolerability. Vaccines and granulocyte-macrophage colony-stimulating factor therapies were well tolerated, but all failed to improve the DFS or OS in stage III melanoma patients. In terms of BRAF mutation-positive melanoma, ICIs (nivolumab + ipilimumab, nivolumab, pembrolizumab, ipilimumab; 10 mg/kg) exhibited comparable efficacy to dabrafenib + trametinib, and all these therapies showed significantly better DFS than placebo.

Conclusion

Considering efficacy and tolerability, nivolumab and pembrolizumab seem to be preferable adjuvant therapies for patients with stage III-IV melanoma. For BRAF mutation-positive patients, more RCTs are still required to determine which is better between ICIs and targeted therapy.

The role of interferons in ovarian cancer progression: Hinderer or promoter?

Ovarian cancer (OC) is a common gynecologic malignancy with poor prognosis and high mortality. Changes in the OC microenvironment are closely related to the genesis, invasion, metastasis, recurrence, and drug-resistance. The OC microenvironment is regulated by Interferons (IFNs) known as a type of important cytokines. IFNs have a bidirectional regulation for OC cells growth and survival. Meanwhile, IFNs positively regulate the recruitment, differentiation and activation of immune cells. This review summarizes the secretion and the role of IFNs. In particular, we mainly elucidate the actions played by IFNs in various types of therapy. IFNs assist radiotherapy, targeted therapy, immunotherapy and biotherapy for OC, except for some IFN pathways that may cause chemo-resistance. In addition, we present some advances in OC treatment with the help of IFN pathways. IFNs have the ability to powerfully modulate the tumor microenvironment and can potentially provide new combination strategies for OC treatment.

Health-related quality of life in stage III-IV melanoma treated with targeted therapy or immunotherapy: A systematic review on the adequacy of reporting and clinical issues in phase III randomized controlled trials

Cutaneous melanoma represents around over 90% of all melanoma. With more effective treatments able to extend patients' survival, health-related quality of life (HRQOL) is increasingly becoming an important endpoint in cancer clinical trials. They are often secondary outcomes measured in phase III randomized controlled trials and their implementation, collection, analysis, and reporting can be challenging methodologically. For these reasons, an increasing number of international recommendations introduced the standards regarding the conduct of HRQOL. In this systematic review, we appraise the adequacy of HRQOL reporting in phase III randomized controlled trials of stage III-IV cutaneous melanoma and the clinical issues of immunotherapy and small-molecular-targeted therapy on HRQOL. Our search strategy totally got 55 articles, and only 13 studies met all inclusion criteria. Findings suggest that most treatments did not yield significant improvements in HRQOL but kept baseline levels, accompanied by prolonged survival and acceptable toxicity. Except for some existing limitations, reporting of HRQOL has made encouraging progress during the period covered by our search, but some aspects still need further optimization.

Comparative efficacy and safety of adjuvant nivolumab versus other treatments in adults with resected melanoma: a systematic literature review and network meta-analysis

Background

Immune checkpoint inhibitors and targeted therapies are approved for adjuvant treatment of patients with resected melanoma; however, they have not been compared in randomized controlled trials (RCTs). We compared the efficacy and safety of adjuvant nivolumab with other approved treatments using available evidence from RCTs in a Bayesian network meta-analysis (NMA).

Methods

A systematic literature review was conducted through May 2019 to identify relevant RCTs evaluating approved adjuvant treatments. Outcomes of interest included recurrence-free survival (RFS)/disease-free survival (DFS), distant metastasis-free survival (DMFS), all-cause grade 3/4 adverse events (AEs), discontinuations, and discontinuations due to AEs. Time-to-event outcomes (RFS/DFS and DMFS) were analyzed both assuming that hazard ratios (HRs) are constant over time and that they vary.

Results

Of 26 identified RCTs, 19 were included in the NMA following a feasibility assessment. Based on HRs for RFS/DFS, the risk of recurrence with nivolumab was similar to that of pembrolizumab and lower than that of ipilimumab 3 mg/kg, ipilimumab 10 mg/kg, or interferon. Risk of recurrence with nivolumab was similar to that of dabrafenib plus trametinib at 12 months, however, was lower beyond 12 months (HR [95% credible interval] at 24 months, 0.46 [0.27–0.78]; at 36 months, 0.28 [0.14–0.59]). Based on HRs for DMFS, the risk of developing distant metastases was lower with nivolumab than with ipilimumab 10 mg/kg or interferon and was similar to dabrafenib plus trametinib.

Conclusion

Adjuvant therapy with nivolumab provides an effective treatment option with a promising risk–benefit profile.

Systemic Therapy for Melanoma: ASCO Guideline

PURPOSE

To provide guidance to clinicians regarding the use of systemic therapy for melanoma.

METHODS

ASCO convened an Expert Panel and conducted a systematic review of the literature.

RESULTS

A systematic review, one meta-analysis, and 34 additional randomized trials were identified. The published studies included a wide range of systemic therapies in cutaneous and noncutaneous melanoma.

RECOMMENDATIONS

In the adjuvant setting, nivolumab or pembrolizumab should be offered to patients with resected stage IIIA/B/C/D BRAF wild-type cutaneous melanoma, while either of those two agents or the combination of dabrafenib and trametinib should be offered in BRAF-mutant disease. No recommendation could be made for or against the use of neoadjuvant therapy in cutaneous melanoma. In the unresectable/metastatic setting, ipilimumab plus nivolumab, nivolumab alone, or pembrolizumab alone should be offered to patients with BRAF wild-type cutaneous melanoma, while those three regimens or combination BRAF/MEK inhibitor therapy with dabrafenib/trametinib, encorafenib/binimetinib, or vemurafenib/cobimetinib should be offered in BRAF-mutant disease. Patients with mucosal melanoma may be offered the same therapies recommended for cutaneous melanoma. No recommendation could be made for or against specific therapy for uveal melanoma.

Systemic adjuvant therapy for adult patients at high risk for recurrent melanoma: A systematic review

Cutaneous melanoma is typically treated with wide local excision and, when appropriate, a sentinel node biopsy. Many patients are cured with this approach but for patients who have cancers with high risk features there is a significant risk of local and distant relapse and death. Interferon-based adjuvant therapy was recommended in the past but had modest results with significant toxicity. Recently, new therapies (immune checkpoint inhibitors and targeted therapies) have been found to be effective in the treatment of patients with metastatic melanoma and many of these therapies have been evaluated and found to be effective in the adjuvant treatment of high risk patients with melanoma. This systematic review of adjuvant therapies for cutaneous and mucosal melanoma was conducted for Ontario Health (Cancer Care Ontario) as the basis of a clinical practice guideline to address the question of whether patients with completely resected melanoma should be considered for adjuvant systemic therapy and which adjuvant therapy should be used.

Patient Experience Captured by Quality-of-Life Measurement in Oncology Clinical Trials

IMPORTANCE

Quality of life (QoL) is an important consideration in cancer medicine, especially because drugs are becoming more costly and may only result in modest gains in overall survival. However, there has been no descriptive analysis for the points at which QoL is measured in cancer trials.

OBJECTIVE

To estimate the prevalence of studies that measure QoL at different points and see how many studies measure QoL for the entirety of a patient's life.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional analysis includes all articles on oncology clinical trials in the 3 highest-impact oncology journals, published between July 2015 and June 2018, that reported QoL outcomes.

MAIN OUTCOMES AND MEASURES

Data were abstracted on when QoL was assessed and the characteristics of these studies.

RESULTS

For all 149 studies that met inclusion criteria, QoL assessment was high during treatment (104 articles [69.8%]), during follow-up (81 articles [54.4%]), and after the end of the intervention (68 articles [45.6%]). In 5 of the 149 studies (3.4%), QoL was assessed until death, including in only 1 of the 74 studies on metastatic or incurable cancers. Among these 5 studies, only 1 (20%) used a drug intervention, 1 (20%) used a behavioral intervention, and 2 (40%) used a radiation intervention; only 1 of 5 was in the metastatic setting. The number of studies that reported a positive QoL outcome (ie, QoL outcome was more favorable in the intervention group than in the control group) was between 42 of 81 articles (51.9%) and 16 of 28 articles (57.1%) for most QoL assessment points but only 1 of 5 articles (20%) for studies measuring QoL until death.

CONCLUSIONS AND RELEVANCE

This study found that most clinical trials assessed QoL during the treatment or intervention and often during a given amount of follow-up but infrequently assessed QoL on disease progression and rarely followed QoL until the end of the patient's life. Most studies reporting QoL until the end of life reported worse QoL outcomes for the intervention group than the control group. Future research and policy recommendations should consider not just short-term QoL outcomes but QoL outcomes throughout the patient's cancer care.

Comparative efficacy and safety of dabrafenib in combination with trametinib versus competing adjuvant therapies for high-risk melanoma

Aim To conduct a systematic literature review of high-risk resectable cutaneous melanoma adjuvant therapeutics and compare safety and efficacy. Methods: The systematic literature review included randomized controlled trials investigating: dabrafenib plus trametinib (DAB + TRAM), nivolumab, pembrolizumab, ipilimumab, vemurafenib, chemotherapy and interferons. Outcomes included overall survival (OS), relapse-free survival, distant metastasis-free survival and safety. All outcomes were synthesized using Bayesian network meta-analysis. Results: Across relapse-free survival, distant metastasis-free survival and OS, DAB + TRAM had the lowest estimated hazards of respective events relative to all other treatments (exception relative to nivolumab in OS). Differences were significant relative to placebo, chemotherapy, interferons and ipilimumab. Conclusion: DAB + TRAM has improved efficacy over historical treatment options (ipilimumab, interferons and chemotherapy) and comparable efficacy with other targeted and immune checkpoint inhibitors.

Quality of life measurement in skin cancer patients: literature review and position paper of the European Academy of Dermatology and Venereology Task Forces on Quality of Life and Patient Oriented Outcomes, Melanoma and Non-Melanoma Skin Cancer

The European Academy of Dermatology and Venereology (EADV) Task Forces (TFs) on Quality of Life (QoL) and Patient Oriented Outcomes, Melanoma and Non-Melanoma Skin Cancer (NMSC) present a review of the literature and position statement on health-related (HR) QoL assessment in skin cancer patients. A literature search was carried out to identify publications since 1980 that included information about the impact of SC on QoL. Generic, dermatology-specific, cancer-specific, SC-specific, facial SC-specific, NMSC-specific, basal cell carcinoma-specific and melanoma-specific QoL questionnaires have been used to assess HRQoL in SC patients. HRQoL was assessed in the context of creation and validation of the HRQoL instruments, clinical trials, comparison of QoL in SC and other cancers, other diseases or controls, HRQoL assessment after treatment, comorbidities, behaviour modification, predictors of QoL and survival, supportive care needs, coping strategies and fear of cancer recurrence. The most widely used instruments for HRQoL assessment in SC patients are the European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30), the Functional Assessment of Cancer Therapy-Melanoma (FACT-M), Skin Cancer Index (SCI), Short Form 36 Item Health Survey (SF-36) and the Dermatology Life Quality Index (DLQI). The TFs recommend the use of the cancer-specific EORTC QLQ-C30, especially in late stages of disease, and the melanoma-specific FACT-M and SC-specific SCI questionnaires. These instruments have been well validated and used in several studies. Other HRQoL instruments, also with good basic validation, are not currently recommended because the experience of their use is too limited. Dermatology-specific HRQoL instruments can be used to assess the impact of skin-related problems in SC. The TFs encourage further studies to validate HRQoL instruments for use in different stages of SC, in order to allow more detailed practical recommendations on HRQoL assessment in SC.

Health-related quality of life analysis in stage III melanoma patients treated with adjuvant dendritic cell therapy

BACKGROUND

Health-related quality of life (HRQoL) is an important issue in the rapidly evolving field of adjuvant treatment for stage III melanoma. Dendritic cell vaccination is one of the adjuvant forms of therapy currently investigated.

METHODS

We enrolled adults with stage III melanoma to receive adjuvant dendritic cell vaccination after a complete radical lymph node dissection. HRQoL assessment was one of the secondary endpoints of this trial and investigated with the EORTC-QLQ-C30 questionnaire at baseline and week 26.

RESULTS

Fifteen patients with a median age of 50 years were included in the study, with twelve evaluable patients on study at time of the second questionnaire. Global health status and role functioning improved clinically relevant with a mean difference of 15 (p = 0.010) and 26 points (p = 0.005), respectively.

DISCUSSION

Despite the small number of patients, we found a clinically relevant improved global health status. Besides, compared to the other investigated therapies, toxicity of dendritic cell vaccination is low, which supports our finding.

CONCLUSION

This is the first description of HRQoL in melanoma patients receiving dendritic cell vaccination. We show the expected improvement in global health status after surgical treatment of stage III melanoma. Thus, adjuvant dendritic cell vaccination does not seem to hamper this improvement, as shown in our small explorative study.

Multimethod assessment of baseline depression and relationship to hepatitis C treatment discontinuation

Objective The primary study objective is to determine which measures of depression are associated with early discontinuation of hepatitis C virus infection treatment and to determine which measure best characterizes the depression that develops during treatment. Methods Seventy-eight treatment-naïve subjects who initiated pegylated interferon/ribavirin treatment for hepatitis C virus infection were included. Baseline depression was assessed with the Structured Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), the Hamilton Depression Rating Scale, and the Beck Depression Inventory-II. The latter two measures were repeated at treatment weeks 12 and 24. Results Depression scores, as measured by the three instruments, lacked adequate consistency. Baseline depression as measured by the Beck Depression Inventory-II, but not by the other scales, was associated with early treatment discontinuation at weeks 12 and 24. Changes in depression during treatment were restricted to somatic symptoms. Of those who completed treatment, those who were not depressed at baseline tended to demonstrate significant depression increases during treatment. Conclusion The Beck Depression Inventory-II is recommended to assess depression prior to hepatitis C virus infection treatment. Somatic symptoms of depression should be monitored during treatment. Baseline depression as measured by the Beck Depression Inventory-II was associated with early treatment discontinuation. The Beck Depression Inventory-II, Structured Interview for DSM-IV, and Hamilton Depression Rating Scale yielded results that were not consistent with each other in this sample. Future research should focus on standardizing depression assessment in medically ill populations to identify measures that predict treatment discontinuation.

Significance and implications of FDA approval of pembrolizumab for biomarker-defined disease

The U.S. Food and Drug Administration (FDA) recently approved pembrolizumab, an anti- programmed cell death protein 1 cancer immunotherapeutic, for use in advanced solid tumors in patients with the microsatellite-high/DNA mismatch repair-deficient biomarker. This is the first example of a tissue-agnostic FDA approval of a treatment based on a patient’s tumor biomarker status, rather than on tumor histology. Here we discuss key issues and implications arising from the biomarker-based disease classification implied by this historic approval.

Immunomodulatory and antitumor effects of type I interferons and their application in cancer therapy

During the last decades, the pleiotropic antitumor functions exerted by type I interferons (IFNs) have become universally acknowledged, especially their role in mediating interactions between the tumor and the immune system. Indeed, type I IFNs are now appreciated as a critical component of dendritic cell (DC) driven T cell responses to cancer. Here we focus on IFN-α and IFN-β, and their antitumor effects, impact on immune responses and their use as therapeutic agents. IFN-α/β share many properties, including activation of the JAK-STAT signaling pathway and induction of a variety of cellular phenotypes. For example, type I IFNs drive not only the high maturation status of DCs, but also have a direct impact in cytotoxic T lymphocytes, NK cell activation, induction of tumor cell death and inhibition of angiogenesis. A variety of stimuli, including some standard cancer treatments, promote the expression of endogenous IFN-α/β, which then participates as a fundamental component of immunogenic cell death. Systemic treatment with recombinant protein has been used for the treatment of melanoma. The induction of endogenous IFN-α/β has been tested, including stimulation through pattern recognition receptors. Gene therapies involving IFN-α/β have also been described. Thus, harnessing type I IFNs as an effective tool for cancer therapy continues to be studied.

A systematic review of yttrium-90 radioembolization for unresectable liver metastases of melanoma

PURPOSE

To assess the effectiveness of yttrium-90 (⁹⁰Y) radioembolization in the treatment of unresectable liver metastases of melanoma.

METHODS

PubMed and EMBASE were systemically searched for all English language studies related to ⁹⁰Y radioembolization for unresectable liver metastases of melanoma, including clinical trials, observational studies, and abstracts from conferences, published between January 1991 and March 2016.

RESULTS

A total of 12 reports (7 observational studies and 5 abstracts from conferences) involving 255 patients were included in the analysis. The primary sites of melanoma were cutaneous (n=22; 8.6%), ocular (n=197; 77.3%), rectal (n=3; 1.2%), and unknown (n=33; 12.9%). The median disease control rate at 3 months was 73.6% (range, 58.3%-88.9%). Among the 207 patients for whom tumor response at 3 months was reported, complete response was seen in 1.0% (2/207), partial response was seen in 19.3% (40/207), stable disease was seen in 46.9% (97/207), and progressive disease was seen in 32.9% (68/207). The median survival was 10 months (range, 7-13.4 months), and the median 1-year survival rate was 34.6% (range, 23%-80%). Complications of ⁹⁰Y radioembolization were reported in 13 cases. The most common side effects were fatigue (median, 36.1%), abdominal pain (median, 17.8%), and nausea (median, 15.0%).

CONCLUSIONS

⁹⁰Y radioembolization is a promising alternative therapy for the treatment of unresectable liver metastases of melanoma, with encouraging effects on disease control and survival. Some complications can occur, and side effects are frequent but mild.

Greater decline in memory and global neurocognitive function in HIV/hepatitis C co-infected than in hepatitis C mono-infected patients treated with pegylated interferon and ribavirin

The human immunodeficiency virus (HIV), hepatitis C virus (HCV), and the treatment of HCV with pegylated interferon and ribavirin (IFN/RBV) have been associated with neurocognitive and psychiatric abnormalities. The goal of this research was to prospectively evaluate neurocognitive functioning among a group of HCV mono-infected and HIV/HCV co-infected patients during the first 24 weeks of IFN/RBV treatment while accounting for practice effects, normal variations in change over time, and variations in IFN/RBV treatment exposure. Forty-four HCV mono-infected and 30 HIV/HCV co-infected patients were enrolled in a prospective study of patients beginning on IFN/RBV for chronic HCV infection. Patients were administered a depression inventory, a measure of fatigue, a structured psychiatric interview, and a neurocognitive battery at baseline and 24 weeks after initiation of treatment. Analyses were conducted to explore possible associations between neurocognitive functioning and the following: HIV/HCV co-infection vs. HCV mono-infection, IFN and RBV treatment exposure, psychiatric status, liver disease stage, and other medical characteristics. At baseline, there were no significant differences between the two groups' neuropsychiatric or neurocognitive function other than the mono-infected group had significantly higher reports of fatigue (p = 0.033). Over the course of 24 weeks of treatment after controlling for practice effects, the HIV/HCV co-infected patients experienced significantly greater declines in memory (t(56) = 2.14, p = 0.037) and global neurocognitive functioning (t(53) = 2.28, p = 0.027). In a well-characterized sample of mono-infected and co-infected patients, it appears that persons with HIV/HCV co-infection are potentially more vulnerable to neurocognitive sequalae during HCV treatment.

Health-related quality of life with adjuvant ipilimumab versus placebo after complete resection of high-risk stage III melanoma (EORTC 18071): secondary outcomes of a multinational, randomised, double-blind, phase 3 trial

BACKGROUND

The EORTC 18071 phase 3 trial compared adjuvant ipilimumab with placebo in patients with stage III melanoma. The primary endpoint, recurrence-free survival, was significantly longer in the ipilimumab group than in the placebo group. Investigator-reported toxic effects of ipilimumab consisted mainly of skin, gastrointestinal, endocrine, and hepatic immune-related adverse events. Adjuvant treatment with ipilimumab in this setting was approved in October, 2014, by the US Food and Drug Administration based on the results of the primary outcome of this trial. Here, we report the results of the secondary endpoint, health-related quality of life (HRQoL), of this trial.

METHODS

EORTC 18071 was a multinational, double-blind, randomised, phase 3 trial in patients with stage III cutaneous melanoma (excluding lymph node metastasis ≤1 mm or in-transit metastasis) in 19 countries worldwide. Participants were randomly assigned (1:1) centrally by an interactive voice response system, to receive either ipilimumab 10 mg/kg or placebo every 3 weeks for four doses, then every 3 months for up to 3 years. Using a minimisation technique, randomisation was stratified by disease stage and geographical region. HRQoL was assessed with the EORTC QLQ-C30 quality-of-life instrument at baseline, weeks 4, 7, 10, and 24, and every 12 weeks thereafter up to 2 years, irrespective of disease progression. Results were summarised by timepoint and in a longitudinal manner in the intention-to-treat population. Two summary scores were calculated for each HRQoL scale: the average score reported during induction (ipilimumab or placebo at a dose of 10 mg/kg, administered as one single dose at the start of days 1, 22, 43, and 64-ie, four doses in 3 weeks), and the average score reported after induction. A predefined threshold of a 10 point difference between arms was considered clinically relevant. The primary HRQoL endpoint was the global health scale, with the predefined hypothesis of no clinically relevant differences after induction between groups. This trial is registered with EudraCT, number 2007-001974-10, and ClinicalTrials.gov, number NCT00636168.

FINDINGS

Between July 10, 2008, and Aug 1, 2011, 951 patients were randomly assigned to treatment: 475 in the ipilimumab group and 476 in the placebo group. Compliance with completing the HRQoL questionnaire was 893 (94%) of 951 patients at baseline, 693 (75%) of 924 at week 24, and 354 (51%) of 697 at week 108. Patient mean global health scores during (77·32 [SD 17·36] vs 72·96 [17·82]; p=0·00011) and after induction (76·48 [17·52] vs 72·32 [18·60]; p=0·00067) were statistically significantly different between groups but were not clinically relevant. Mean global health scores differed most between the groups at week 7 (77 [SD 19] in the placebo group vs 72 [22] in the ipilimumab group) and week 10 (77 [20] vs 70 [23]). Mean HRQoL scores differed by more than 10 points at week 10 between treatment groups for diarrhoea (7·67 [SD 17·05] for placebo vs 18·17 [28·35] for ipilimumab) and insomnia (15·17 [22·53] vs 25·60 [29·19]).

INTERPRETATION

Despite increased toxicity, which led to treatment discontinuation for most patients during the induction phase of ipilimumab administration, overall HRQoL, as measured by the EORTC QLQ-C30, was similar between groups, as no clinically relevant differences (10 points or more) in global health status scores were observed during or after induction. Clinically relevant deterioration for some symptoms was observed at week 10, but after induction, no clinically relevant differences remained. Together with the primary analysis, results from this trial show that treatment with ipilimumab results in longer recurrence-free survival compared with that for treatment with placebo, with little impairment in HRQoL despite grade 3-4 investigator-reported adverse events.

Phase III Randomized Study of 4 Weeks of High-Dose Interferon-α-2b in Stage T2bNO, T3a-bNO, T4a-bNO, and T1-4N1a-2a (microscopic) Melanoma: A Trial of the Eastern Cooperative Oncology Group-American College of Radiology Imaging Network Cancer Research Group (E1697)

Purpose To test the efficacy of 4 weeks of intravenous (IV) induction with high-dose interferon (IFN) as part of the Eastern Cooperative Oncology Group regimen compared with observation (OBS) in patients with surgically resected intermediate-risk melanoma. Patients and Methods In this intergroup international trial, eligible patients had surgically resected cutaneous melanoma in the following categories: (1) T2bN0, (2) T3a-bN0, (3) T4a-bN0, and (4) T1-4N1a-2a (microscopic). Patients were randomly assigned to receive IFN α-2b at 20 MU/m²/d IV for 5 days (Monday to Friday) every week for 4 weeks (IFN) or OBS. Stratification factors were pathologic lymph node status, lymph node staging procedure, Breslow depth, ulceration of the primary lesion, and disease stage. The primary end point was relapse-free survival. Secondary end points included overall survival, toxicity, and quality of life. Results A total of 1,150 patients were randomly assigned. At a median follow-up of 7 years, the 5-year relapse-free survival rate was 0.70 (95% CI, 0.66 to 0.74) for OBS and 0.70, (95% CI, 0.66 to 0.74) for IFN ( P = .964). The 5-year overall survival rate was 0.83 (95% CI, 0.79 to 0.86) for OBS and 0.83 (95% CI, 0.80 to 0.86) for IFN ( P = .558). Treatment-related grade 3 and higher toxicity was 4.6% versus 57.9% for OBS and IFN, respectively ( P < .001). Quality of life was worse for the treated group. Conclusion Four weeks of IV induction as part of the Eastern Cooperative Oncology Group high-dose IFN regimen is not better than OBS alone for patients with intermediate-risk melanoma as defined in this trial.

Systematic review of psychosocial outcomes for patients with advanced melanoma

BACKGROUND

New advanced melanoma therapies are associated with improved survival; however, quality of survivorship, particularly psychosocial outcomes, for patients overall and those treated with newer therapies is unclear.

OBJECTIVE

Synthesize qualitative and quantitative evidence about psychosocial outcomes for advanced (stage III/IV) melanoma patients.

METHODS

Five databases were searched (01/01/1980 to 31/01/2016). Inclusion criteria were as follows: advanced melanoma patients or sub-group analysis; assessed psychosocial outcomes; and English language.

RESULTS

Fifty-two studies met review criteria (4 qualitative, 48 quantitative). Trials comprise mostly medical not psychosocial interventions, with psychosocial outcomes assessed within broader quality of life measures. Patients receiving chemotherapy or IFN-alpha showed decreased emotional and social function and increased distress. Five trials of newer therapies appeared to show improvements in emotional and social function. Descriptive studies suggest that patients with advanced, versus localized disease, had decreased emotional and social function and increased distress. Contributors to distress were largely unexplored, and no clear framework described coping/adjustment trajectories. Patients with advanced versus localized disease had more supportive care needs, particularly amount, quality, and timing of melanoma-related information, communication with and emotional support from clinicians. Limitations included: lack of theoretical underpinnings guiding study design; inconsistent measurement approaches; small sample sizes; non-representative sampling; and cross-sectional design.

CONCLUSIONS

Quality trial evidence is needed to clarify the impact of treatment innovations for advanced melanoma on patients' psychosocial well-being. Survivorship research and subsequent translation of that knowledge into programs and services currently lags behind gains in the medical treatment of advanced melanoma, a troubling circumstance that requires immediate and focused attention.
