MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There is a major unmet need for well tolerated and effective adjuvant therapy for high risk melanoma, that is, melanoma that has been removed but the patients have a 50%+ risk of relapse over 5 years, and a 50%+ risk of death over 10 years from melanoma. Since nivolumab is an active and well tolerated drug in metastatic disease, it seemed reasonable to test it after surgery to prevent recurrence. Since ipilimumab is approved for resected stage III melanoma in the US as adjuvant therapy, that was the control arm for comparison, and that is an active control, which prolongs relapse free and overall survival comared to placebo.

MedicalResearch.com: What is the background for this study?

Response: Red-headed people are making up to 1~2% of the world’s population. They carry “red hair color” variants of MC1R (MC1R-RHC) which are responsible for their characteristic features, including red hair, pale skin, freckles and poor tanning ability.

MC1R-RHC also increases risk of melanoma, the deadliest form of skin cancer. People without red hair but with a single copy of MC1R-RHC also have an increased melanoma risk, who may make more than 50% of the northern European population. It is unknown why redheads are more prone to melanoma, and whether the activity of red hair color variants could be restored for therapeutic benefits.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The recently published article is a review paper- we reviewed previous laboratory studies of the effects of nicotinamide on normal pigment cells and on melanoma, and also the previous studies showing that nicotinamide can reduce rates of non-melanoma skin cancer (basal cell and squamous cell carcinoma) in high risk patients. We have not done any clinical investigations of nicotinamide as a preventive agent for melanoma.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response:  Laboratory studies show lithium, an activator of  the Wnt/ß-catenin signaling pathway, slows melanoma progression, but no published epidemiologic studies have explored this association. We conducted a retrospective cohort study of adult white Kaiser Permanente Northern California members (n=2,213,848) from 1997-2012 to examine the association between lithium use and melanoma risk.

Our main finding is that lithium-exposed individuals had a reduced incidence of melanoma, did not develop very thick tumors (> 4 mm Breslow depth) or extensive disease at presentation, and had decreased melanoma-specific mortality compared to unexposed individuals suggesting a possible role for lithium in altering melanoma risk.

MedicalResearch.com: What is the background for this study?

JE: Previous studies on diagnostic accuracy in interpreting melanocytic lesions exist but have small sample size, inclusion of experts only, or small numbers of specimens. We sought to examine accuracy and reproducibility in melanocytic skin lesions by improving upon the methodological limitations of previous studies. Specifically, we recruited a large national sample of practicing community and academic pathologists with a wide range of experience, and we utilized a large sample of biopsy cases that were carefully selected. Given that diagnostic errors can lead to patient deaths and invasive melanoma kills more than 9,000 Americans each year, we wanted to study the issue of diagnostic accuracy in interpreting melanocytic skin lesions in a very robust fashion.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Regressing nevi, which are frequently associated with halo phenomenon, occur in approximately 1% of the general population. In patients with melanoma, spontaneous or treatment-related depigmentation of the skin (vitiligo) is sometimes observed. Although humoral and cellular immune responses may play a crucial role in their development, immune reactions to benign melanocytic nevi (BMN) without a halo are extremely rare in both the general population and in patients with melanoma.

This publication reports a rare case with multiple metastatic melanomas who showed a remarkable clinical response to nivolumab with a simultaneous prominent immune reaction to multiple BMN without halo phenomenon. This rare phenomenon may be associated with dramatic efficacy of nivolumab in melanoma patients.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We found that a non-invasive adhesive patch applied to the skin over a pigmented skin lesion allowed us to capture enough genetic material from the lesion to analyze and predict if that lesion is likely to be melanoma, meaning a biopsy is warranted, or if it is likely benign, meaning the patient would not need a skin biopsy.

In this study, we asked dermatologists to use their clinical judgement to decide if they would recommend biopsying a skin lesion based on photos and information about the lesion and the patients, such as the patient’s age, personal and family history of skin cancer, and if the lesion was new or changing. We then provided them the read out of the gene test and asked them how this influence their decision. We found that with this test result, dermatologists were more accurate in their decision making, meaning they were more likely to recommend biopsy of melanomas and less likely to biopsy harmless moles than they were without the test. This is important as it means this test has the potential to reduce the number of unnecessary skin biopsies performed, saving patients from undergoing a procedure and having a scar as a result, without increasing the risk of missing a melanoma.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Although IPI was approved for the treatment of melanoma at dosage of 3 mg/kg, a dose-ranging phase 2 trial suggested longer overall survival (OS) but more treatment-related adverse events with ipilimumab 10 mg/kg vs 3 mg/kg. However, the study MDX010-020 (randomized phase III study which compared ipilimumab 3 mg/kg + gp100 vaccination and ipilimumab 3mg/kg + placebo vs gp100 vaccination + placebo) performed as second line treatment of advanced melanoma patients, showed an OS curve similar to that of the study CA184-169 (randomized phase III study which compared dacarbazine + ipilimumab 10 mg/kg to dacarbazine + placebo) as first line treatment of metastatic melanoma.

For this reason FDA approved ipilimumab at dosage of 3 mg/kg as first and second line treatment for advanced melanoma, but asked for a randomized phase III study of comparison of ipilimumab at the different dosage in order to explore if there was a difference in the outcome of patients with different dosages.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Malignant melanoma is an aggressive disease and is the cause of the majority of skin cancer deaths. In particular, older individuals have a much poorer prognosis for melanoma and are more resistant to targeted therapy than compared to young individuals. A recently published study from our lab has shown that age-related changes in secreted factors in the microenvironment can drive melanoma progression and therapy resistance.

Klotho is a protein whose expression levels decreases with aging. In this study, we have shown that a decrease in klotho levels in the aged microenvironment drives melanoma aggression and therapy resistance by promoting the oncogenic signaling pathway Wnt5A. We also have shown that reconstituting klotho levels in the aged microenvironment by using rosiglitazone, an FDA-approved drug used to treat diabetes, can reduce tumor burden in aged mice. We also show that Klotho expression is decreased in therapy-resistant melanoma tumors. Reconstituting klotho levels in therapy-resistant melanoma cells by treating with rosiglitazone can inhibit Wnt5A levels and MAPK pathway. We also show that rosiglitazone can significantly decrease therapy-resistant tumor burden in the aged mice, but not in the young.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Melanoma is the most deadly form of skin cancer with more than 75,000 newly diagnosed cases in the US each year. Over the years, various genetic driver mutations have been identified that cause melanoma, including mutations in the genes BRAF and NRAS. Recent genetic insights into the development of melanoma showed that also mutations in NF1 can lead to melanoma. While there are targeted therapies available for BRAF-mutant melanoma, thus far no such therapies are available for NF1-mutant melanoma. We identified that using a combination of an ERK inhibitor, SCH772984, and the antidiabetic drug phenformin could provide a novel therapeutic strategy for NF1-mutatnt melanomas.

Robert P. Dellavalle, MD, PhD, MSPH
Dermatology Service, Denver Veterans Affairs Medical Center, Denver, Colorado
Department of Dermatology, University of Colorado School of Medicine, Aurora

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Skin cancer remains the most common cancer in the U.S., despite ongoing efforts to address this major public health problem. Over 9,000 deaths occur annually, and mortality rates continue to increase faster than those associated with any other preventable cancer. Malignant melanoma, the deadliest type of skin cancer, accounts for the overwhelming majority of these deaths.

Our study identified regional and state differences in the incidence and mortality rates of melanoma in the United States. We found that the Northeast, specifically New England, represents the only U.S. region in which the majority of states experienced a reduction in both incidence and death rates over the ten-year period between 2003 and 2013.

Is Skin Cancer Screening Cost Effective?

MedicalResearch.com Interview with:
Isabelle Hoorens, MD, PhD

Department of Dermatology
Ghent University Hospital
Ghent, Belgium

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In this study we questioned whether a population-based screening for skin cancer is cost-effective.

In addition we compared the cost-effectiveness of two specific screening techniques. The first technique, a lesion-directed screening being a free-of-charge skin cancer check of a specific lesion meeting 1 or more of the following criteria: ABCD rule (asymmetry, border irregularity, color variation, and diameter >6 mm), “ugly duckling” sign, new lesion lasting longer than 4 weeks, or red nonhealing lesions.

The second screening technique consisted of a systematic total body examination in asymptomatic patients. A clinical screening study was performed in Belgium in 2014. Continue reading

Pembrolizumab Found to Be Cost-Effective in Advanced Melanoma

MedicalResearch.com: What is the background for this study? 

Response: Advanced melanoma have previously been known to be a disease with a dismal prognosis. Over the last few years, clinical trials data and real-world clinical experience of checkpoint inhibitors have significantly changed the treatment landscape for advanced melanoma patients. This was first demonstrated with the Anti-CTLA4 Ab Ipilimumab, and more recently with the Anti-PD1 Ab pembrolizumab. Whilst we have seen dramatic improvements in disease control with the use of these agents, the high costs of these drugs may be prohibitive to the average patient who has to pay out-of-pocket and potentially may place significant burdens on healthcare systems. There is a need to rationally assess the cost-effectiveness of these new agents, specifically addressing the potential benefits to the individual patient and to society, whilst balancing the costs that such a treatment may entail.

The assessment of cost-effectiveness of a particular treatment is extremely important in Hong Kong, as this has direct implications on drug reimbursement and accessibility of the particular drug in question at public hospitals in Hong Kong. The aim of the study is to assess the cost-effectiveness of pembrolizumab in patients with advanced melanoma used in the first-line setting in Hong Kong, and comparing it to (1) ipilimumab and (2) cytotoxic chemotherapy. Cytotoxic chemotherapy chosen for comparison were drugs commonly used in the first line setting in Hong Kong, which included dacarbazine, temozolomide and carboplatin+paclitaxel combination. It is important to note that whilst ipilimumab is registered for this indication in Hong Kong, there is no reimbursement of this drug by the Hospital Authority in Hong Kong and patients have to pay out-of-pocket. The cost of ipilimumab and the associated side effects has been prohibitive to most advanced melanoma patients in the public setting.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Interest for this study arose from a realization that a large number of deaths from thin melanomas have been documented in SEER. Since prognosis worsens with depth for thicker melanomas, we sought to evaluate whether it was the “thicker” of the thin melanomas that accounted for most of the deaths. We were surprised to find that when we restricted our study to melanomas diagnosed at Stage I and II, the greatest number of deaths at 10 years caused by these melanomas resulted from those 1.00mm and less in depth. We were also surprised to find that prognosis for ultra-thin melanomas, 0.01-0.25mm in depth, was not better than those 0.26-0.50mm, as we had expected.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Cutaneous melanoma, an aggressive and deadly form of skin cancer, in early stages is often cured with surgery alone. Most patients presenting with advanced-stage disease, however, are not candidates for surgery and drug therapy is the main course of treatment. Around 40-60% of melanomas have a mutation in the BRAF protein. Multiple effective first-line treatment options are available for patients with advanced BRAF-mutated melanoma, which fall under two established classes of drug therapies: targeted therapy and immunotherapy. Presently, it remains uncertain which is the optimal first-line treatment.

In our network meta-analysis we evaluated 15 randomized controlled trials published between 2011 and 2015 assessing the benefits and harms of targeted or immune checkpoint inhibitors in 6662 treatment naïve patients with lymph node metastasis not amenable to surgery or distant metastatic melanoma.

We found that combined BRAF and MEK targeted therapy and PD-1 immunotherapy were both equally effective in improving overall survival. Combined BRAF and MEK inhibition was most effective in improving progression-free survival. PD-1 inhibition was associated with the lowest risk of serious adverse events.

Do Dysplastic Moles Need To Be Re-Excised?

MedicalResearch.com Interview with:
Timothy Patton, DO

Department of Dermatology
Falk Medical Center
University of Pittsburgh Medical Center

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: As dermatologists we are confronted daily with how to manage lesions that are biopsied and diagnosed as dysplastic nevi. These lesions are considered by some to be potential melanoma precursors and by others as benign lesions with little to no malignant potential. Often, particularly for lesions with severe atypia these lesions are re excised. There are no prospective studies or consistent guidelines as to how to manage these lesions. We decided to retrospectively look at the outcome of 451 patients with dysplastic nevi with severe atypia, many of whom had not had their lesions re-excised, who had at least 5 years of follow up to determine if any developed melanoma at the site of the biopsied dysplastic nevus or distantly. We found no cases of metastatic melanoma in patients who did not already have a diagnosis of melanoma. We found two cases of thin melanoma in patients who had their lesions re-excised. Both of those patients were treated with reexcision and did not develop subsequent melanoma metastasis or recurrence. Continue reading

Skin Surveillance Can Be Tailored To Individuals at Higher Risk of Melanoma

The University of Sydney

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The Melanoma Patterns of Care study was a population-based observational study of physicians’ reported clinical management of 2727 patients diagnosed with an in situ or invasive primary melanoma over a 12-month period from October 2006 to 2007 in New South Wales, Australia. This paper investigated the differences between 1052 (39%) patients who were defined as higher risk owing to a family history of melanoma, multiple primary melanomas, or many nevi (moles) compared to patients who did not have any risk factors.

We found that the higher-risk group had a younger mean age at diagnosis compared to those without risk factors, (62 vs 65 years, P < .001) which varied by type of risk factor (56 years for patients with a family history, 59 years for those with many nevi, and 69 years for those with a previous melanoma). These age differences were consistent across all body sites. Among higher-risk patients, those with many nevi were more likely to have melanoma on the trunk (41% vs 29%, P < .001), those with a family history of melanoma were more likely to have melanomas on the limbs (57%vs 42%, P < .001), and those with a personal history were more likely to have melanoma on the head and neck (21% vs 15%, P < .001).

The University of Sydney 

MedicalResearch.com: What is the background for this study?

Response: A clinic for people at high risk of melanoma was established at the Royal Prince Alfred Hospital, Sydney in 2006 as part of a research project to look at the impact of surveillance regime which included regular full body skin examination supported by dermoscopy and total body photography at 6 monthly intervals. If a suspicious lesion was identified, the lesion was either removed or an image of the lesion was captured using digital dermoscopy and the patient returned in 3 months for review.

This study aimed to estimate the costs and benefits from a health system perspective associated with specialised surveillance compared with current routine care high risk people would receive in the community.  Continue reading

MedicalResearch.com: What made you set out to organize this survey?

Response: Before 2011 there were no effective treatment options for metastatic melanoma patients, but that have tremendously changed in the last 5 years. Now we have innovative medicines which are able to prolong overall survival of these patients to more than 18 months, and in some patients, durable responses lasting for up to 10 years are not infrequently reported. However, the access to these medicines is restricted, and patients and physicians are facing more and more difficulties to obtain them. This is especially the case for countries of Eastern and South-Eastern Europe, where majority of patients are still treated with palliative chemotherapy that does not prolong overall survival. We wanted to explore this issue more deeply, to map the access to innovative medicines between 1st May 2015 to 1st May 2016, and particularly the access to first-line treatment recommended by ESMO and EDF/EORTC/EADO guidelines that are based on scientific evidence and which are published in 2015 and 2016.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: To date, findings from studies have been inconsistent. Some studies found a decreased risk of melanoma among sunscreen users, while others found no association or a higher risk of melanoma among sunscreen users. Several studies found that many sunscreen users do not apply sunscreens properly and do not reapply as recommended and stay longer in the sun after using sunscreen and as a result get sunburn and increase their risk of skin cancer.

Our findings suggest higher UV exposure among sunscreen users compared to nonusers. However, those who used sunscreen with high SPF had 33% lower risk of melanoma compared to users of low SPF sunscreens.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Dysplastic nevi (DN) are frequently re-excised following initial biopsy due to concerns for malignant transformation; however, the long-term risk of melanoma developing in mildly or moderately dysplastic nevi with positive histologic margins is unknown. In this cohort study of 590 histologic DN that were followed over 20 years, 6 cases of melanoma (5 in situ) arose in the 304 DN with positive margins that were clinically observed, only 1 of which developed from an excisionally-biopsied dysplastic nevus. One melanoma in situ arose in the 170 cases that underwent complete excision at the outset. The risk of new primary melanoma at other sites of the body was over 9% in both groups.
