Cancer burden in adolescents and young adults in Europe.

BACKGROUND: Cancer epidemiology is unique in adolescents and young adults (AYAs; aged 15-39 years). The European Society for Medical Oncology/European Society for Paediatric Oncology (ESMO/SIOPE) AYA Working Group aims to describe the burden of cancers in AYAs in Europe and across European Union (EU) countries. PATIENTS AND METHODS: We used data available on the Global Cancer Observatory. We retrieved crude and age-standardised (World Standard Population) incidence and mortality rates. We reported about AYA cancer burden in Europe and between 28 EU member states. We described incidence and mortality for all cancers and for the 13 cancers most relevant to the AYA population. RESULTS: Incidence and mortality varied widely between countries with the highest mortality observed in Eastern EU countries. Cancers of the female breast, thyroid and male testis were the most common cancers across countries followed by melanoma of skin and cancers of the cervix. Variations in cancer incidence rates across different populations may reflect different distribution of risk factors, variations in the implementation or uptake of screening as well as overdiagnosis. AYA cancer mortality disparities may be due to variation in early-stage diagnoses, different public education and awareness of cancer symptoms, different degrees of access or availability of treatment. CONCLUSIONS: Our results highlight the future health care needs and requirements for AYA-specialised services to ensure a homogeneous treatment across different countries as well as the urgency for preventive initiatives that can mitigate the increasing burden.

Impact of COVID-19 on social media as perceived by the oncology community: results from a survey in collaboration with the European Society for Medical Oncology (ESMO) and the OncoAlert Network.

BACKGROUND: The COVID-19 pandemic has impacted all aspects of modern-day oncology, including how stakeholders communicate through social media. We surveyed oncology stakeholders in order to assess their attitudes pertaining to social media and how it has been affected during the pandemic. MATERIALS AND METHODS: A 40-item survey was distributed to stakeholders from 8 July to 22 July 2020 and was promoted through the European Society for Medical Oncology (ESMO) and the OncoAlert Network. RESULTS: One thousand and seventy-six physicians and stakeholders took part in the survey. In total, 57.3% of respondents were medical oncologists, 50.6% aged <40 years, 50.8% of female gender and mostly practicing in Europe (51.5%). More than 90% of respondents considered social media a useful tool for distributing scientific information and for education. Most used social media to stay up to date on cancer care in general (62.5%) and cancer care during COVID-19 (61%) given the constant flow of information. Respondents also used social media to interact with other oncologists (78.8%) and with patients (34.4%). Overall, 61.1% of respondents were satisfied with the role that social media was playing during the COVID-19 pandemic. On the other hand, 41.1% of respondents reported trouble in discriminating between credible and less credible information and 30% stated social networks were a source of stress. For this reason, one-third of respondents reduced its use during the COVID-19 pandemic. Regarding meeting attendance, a total of 59.1% of responding physicians preferred in-person meetings to virtual ones, and 51.8% agreed that virtual meetings and social distancing could hamper effective collaboration. CONCLUSION: Social media has a useful role in supporting cancer care and professional engagement in oncology. Although one-third of respondents reported reduced use of social media due to stress during the COVID-19 pandemic, the majority found social media useful to keep up to date and were satisfied with the role social media was playing during the pandemic.

Adolescents and young adults (AYA) with cancer: a position paper from the AYA Working Group of the European Society for Medical Oncology (ESMO) and the European Society for Paediatric Oncology (SIOPE).

It is well recognised that adolescents and young adults (AYA) with cancer have inequitable access to oncology services that provide expert cancer care and consider their unique needs. Subsequently, survival gains in this patient population have improved only modestly compared with older adults and children with cancer. In 2015, the European Society for Medical Oncology (ESMO) and the European Society for Paediatric Oncology (SIOPE) established the joint Cancer in AYA Working Group in order to increase awareness among adult and paediatric oncology communities, enhance knowledge on specific issues in AYA and ultimately improve the standard of care for AYA with cancer across Europe. This manuscript reflects the position of this working group regarding current AYA cancer care, the challenges to be addressed and possible solutions. Key challenges include the lack of specific biological understanding of AYA cancers, the lack of access to specialised centres with age-appropriate multidisciplinary care and the lack of available clinical trials with novel therapeutics. Key recommendations include diversifying interprofessional cooperation in AYA care and specific measures to improve trial accrual, including centralising care where that is the best means to achieve trial accrual. This defines a common vision that can lead to improved outcomes for AYA with cancer in Europe.

Chemoprevention for breast cancer.

Despite the progress that has been made in breast cancer diagnosis and treatment, this disease is still a major health problem, being the most frequently diagnosed cancer and the first leading cause of cancer death among women both in developed and economically developing countries. In some developed countries incidence rate start to decrease from the end of last millennium and this can be explained, at least in part, by the decrease in hormone replacement therapy use by post-menopausal women. Chemoprevention has the potential to be an approach of utmost importance to reduce cancer burden at least among high-risk populations. Tamoxifen and raloxifene are both indicated for the prevention of breast cancer in women at high risk for the development of the disease, although raloxifene may have a more favorable adverse-effect profile, causing fewer uterine cancers and thromboembolic events. Aromatase inhibitors will most probably become an additional prevention treatment option in the near future, in view of the promising results observed in adjuvant trials and the interesting results of the very recently published first chemoprevention trial using an aromatase inhibitor.(2) Despite impressive results in most clinical trials performed to date, chemoprevention is still not widely used. Urgently needed are better molecular risk models to accurately identify high-risk subjects, new agents with a better risk/benefit ratio and validated biomarkers.

Lapatinib ditosylate: expanding therapeutic options for receptor tyrosine-protein kinase erbB-2-positive breast cancer.

Receptor tyrosine-protein kinase erbB-2 (HER2)-positive breast cancer is a specific entity with an aggressive behavior. Trastuzumab, a monoclonal antibody targeting erbB-2 (HER2) deeply transformed the outcome in patients. Nevertheless, resistance to trastuzumab is still a major concern. Lapatinib ditosylate is an orally available, small molecule targeting the tyrosine activity of the HER2 receptor. Lapatinib as a single agent and in combination therapy showed interesting activity in trastuzumab-resistant advanced tumors. In addition, lapatinib use seemed suitable in recurrent locally advanced inflammatory breast cancer and brain metastases. More recently, the Neo-ALTTO (NeoAdjuvant Lapatinib and/or Trastuzumab Treatment Optimisation) trial showed that lapatinib in combination with trastuzumab and paclitaxel significantly improved the pathological complete response in a neoadjuvant setting. Several clinical trials are still ongoing and data that may change current clinical practice are awaited with much interest.
