MedicalResearch.com: What is the background for this study? Would you briefly explain how mitochondrial DNA differs from chromosomal DNA?
TK: Immune checkpoint blockade has changed the way we treat several cancers, including advanced melanoma. Before these therapies, the treatment options were very limited, but now more than half of patients experience significant tumor shrinkage or disease control.
KRM: Despite these advances, many patients still do not respond to treatment. One of the main challenges in cancer medicine today is to find ways to predict which patients will benefit from these therapies before treatment begins. This approach is key to personalizing care and improving outcomes.
RF: Mitochondria are small structures inside our cells that produce the energy needed for cells to function. Unlike most of our DNA, mitochondrial DNA is inherited only from the mother. Scientists can categorize this mitochondrial DNA into groups called haplogroups, based on unique variations in the genetic code. These haplogroups can provide insight into how cells produce energy and may affect a person’s health or response to cancer treatment.

MedicalResearch.com: What are the main types of skin cancer? Is the incidence changing?
Response: The 3 main types of skin cancer are melanoma, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). Skin cancer is the most common cancer in the United States1 and 1 in 5 Americans will develop skin cancer in their lifetime. (2)
The overall incidence has changed as follows:
• Melanoma: Rates doubled over past 30 years from 1982 to 2011.3 It differs by age group.
o Adolescents and adults age 30 and younger: incidence rate is declining
o Older age groups (e.g. 80 and older): incidence rate is increasing
• Squamous Cell Cancer:
o Incidence increased 263% between 1976-1984 and 2000-20104
• Basal Cell Cancer:
o Incidence increased 145% between 1976-1984 and 2000-20104

MedicalResearch.com: What is the background for this study?
Response: Back in 2016, while I was characterising the RNA SAMMSON as essential for mitochondrial translation in melanoma, I noticed that its inhibition was causing cell death across a large spectrum of melanoma cell lines and models, irrespectively of their genetic background and cell state. At that time I still did not know why the effect was so pronounced on melanoma cells, but I knew that antibiotics of the tetracycline family could also block mitochondrial translation and I thought about repurposing them to treat melanoma.

MedicalResearch.com: What is the background for this Roundtable event? Would you describe the mission of the European Commission’s Beating Cancer Plan?
Response: Europe’s Beating Cancer Plan is the first, comprehensive EU strategy on cancer, aimed at tackling the disease through all key stages: prevention; early detection; diagnosis and treatment; and quality of life of cancer patients and survivors. The Plan also aims to create opportunities to improve cancer care through research and innovative projects, such as artificial intelligence, and to promote equal access to knowledge and treatments in cancer care across Europe.
The EADV seeks to create a bridge between the EU health policy agenda and scientific research, by engaging with policymakers, patient organisations and other stakeholders to support a patient centric-approach; tackling melanoma and non-melanoma skin cancers (NMSC) at all stages of the pathway, from prevention to follow-up care.
Through our Roundtable event, the EADV brought together these key stakeholders to evaluate the effectiveness of the EBCP on preventing both melanoma and NMSC, as well as identify joint recommendations that step-up measures towards this goal.
