Abstract
BACKGROUND Cancer is a global public health problem, requiring efficient health system investments to deliver sustainable impact on population health. Access to medicines is a critical component of health systems, having a crucial role in delivering therapeutic benefits. Since 1977, the World Health Organization (WHO) has published a Model List of Essential Medicines (EML) that includes key health interventions for the prevention and control of conditions of public health relevance. Essential medicines are selected for inclusion in the EML based on the evidence of efficacy, safety, therapeutic value, and the potential to impact population health. With the rapid changes in the therapeutic landscape of cancer treatment with new medicine approvals, there is a critical need to select and prioritise specific cancer interventions based on their intrinsic value. MATERIALS AND METHODS The European Society for Medical Oncology (ESMO) has developed a decisional methodology based on a threshold with a minimum set of technical specifications and a consensus-based procedure for decisions to select candidate cancer medicines to be submitted to the WHO for consideration for the WHO EML. RESULTS ESMO recognises the WHO EML as an important reference guide for medicines that all countries should include in their national EMLs. Cancer medicines on the WHO EML are used in the treatment of the majority of cancers, and are recommended in the evidence-based ESMO Clinical Practice Guidelines that medical oncologists use to treat patients. ESMO's submissions to the WHO EML in 2019 and 2021 and their respective outcomes are presented in the manuscript. CONCLUSION Due to the rising costs associated with newly available therapies, structured, reproducible, and field-tested tools to evaluate the added clinical benefit from these therapies need to be implemented in pre-selecting potential candidate medicines to be included in the WHO EML. ESMO is proud to collaborate closely with WHO on this important global public health initiative.

Abstract
INTRODUCTION Off-label use of medicines is generally discouraged. However, several off-patent, low-cost cancer medicines remain off-label for indications in which they are commonly used in daily practice, supported by high-level evidence based on results of phase III clinical trials. This discrepancy may generate prescription and reimbursement obstacles as well as impaired access to established therapies. METHODS A list of cancer medicines that remain off-label in specific indications despite the presence of high-level evidence was generated and subjected to European Society for Medical Oncology (ESMO) expert peer review to assess for accountability of reasonableness. These medicines were then surveyed on approval procedures and workflow impact. The most illustrative examples of these medicines were reviewed by experts from the European Medicines Agency to ascertain the apparent robustness of the supporting phase III trial evidence from a regulatory perspective. RESULTS A total of 47 ESMO experts reviewed 17 cancer medicines commonly used off-label in six disease groups. Overall, high levels of agreement were recorded on the off-label status and the high quality of data supporting the efficacy in the off-label indications, often achieving high ESMO-Magnitude of Clinical Benefit Scale (ESMO-MCBS) scores. When prescribing these medicines, 51% of the reviewers had to implement a time-consuming process associated with additional workload, in the presence of litigation risks and patient anxiety. Finally, the informal regulatory expert review identified only 2 out of 18 (11%) studies with significant limitations that would be difficult to overcome in the context of a potential marketing authorisation application without additional studies. CONCLUSIONS We highlight the common use of off-patent essential cancer medicines in indications that remain off-label despite solid supporting data as well as generate evidence on the adverse impact on patient access and clinic workflows. In the current regulatory framework, incentives to promote the extension of indications of off-patent cancer medicines are needed for all stakeholders.

Abstract
BACKGROUND During recent years, the burden of bureaucracy in clinical research has increased dramatically, adversely impacting the activity of investigators and clinical research teams. Although compliance with the Declaration of Helsinki, the guidelines for Good Clinical Practice (GCP), and other applicable regulations remains unquestionable, their overinterpretation and substitution by the internal operating procedures of sponsors and Contract Research Organizations (CROs) have increased the administrative burden. A survey conducted by the European Society for Medical Oncology (ESMO) Clinical Research Observatory (ECRO) among 940 investigators confirmed that they considered that the administrative burden in clinical research is excessive; that administrative procedures could be reduced without affecting the safety and the rights of the patients and the quality of the data; and that bureaucracy represents an obstacle for clinical research. METHODS A panel of physicians with extensive experience in clinical research, composed by members of the ECRO and the ESMO Scientific Medical and Public Policy divisions, analyzed clinical trial procedures related to administrative workflow, pharmacovigilance, and medical care. RESULTS The panel identified situations that generate debate between investigators and sponsors/CROs and selected real clinical scenarios that exemplify such situations. The panel discussed and proposed specific recommendations for those situations, based on GCP. CONCLUSIONS This initiative aspires to streamline clinical research procedures and to become a platform for discussion among all clinical trial stakeholders, with the aim of promoting the sustainability of clinical research and the care of cancer patients.

Abstract
Background The COVID-19 pandemic has resulted in significant changes to professional and personal lives of oncology professionals globally. The European Society for Medical Oncology (ESMO) Resilience Task Force collaboration aimed to provide contemporaneous reports on the impact of COVID-19 on the lived experiences and well-being in oncology. Methods This online anonymous survey (July-August 2020) is the second of a series of global surveys launched during the course of the pandemic. Longitudinal key outcome measures including well-being/distress (expanded Well-being Index—9 items), burnout (1 item from expanded Well-being Index), and job performance since COVID-19 were tracked. Results A total of 942 participants from 99 countries were included for final analysis: 58% (n = 544) from Europe, 52% (n = 485) female, 43% (n = 409) ≤40 years old, and 36% (n = 343) of non-white ethnicity. In July/August 2020, 60% (n = 525) continued to report a change in professional duties compared with the pre-COVID-19 era. The proportion of participants at risk of poor well-being (33%, n = 310) and who reported feeling burnout (49%, n = 460) had increased significantly compared with April/May 2020 (25% and 38%, respectively; P < 0.001), despite improved job performance since COVID-19 (34% versus 51%; P < 0.001). Of those who had been tested for COVID-19, 8% (n = 39/484) tested positive; 18% (n = 7/39) felt they had not been given adequate time to recover before return to work. Since the pandemic, 39% (n = 353/908) had expressed concerns that COVID-19 would have a negative impact on their career development or training and 40% (n = 366/917) felt that their job security had been compromised. More than two-thirds (n = 608/879) revealed that COVID-19 has changed their outlook on their work-personal life balance. Conclusion The COVID-19 pandemic continues to impact the well-being of oncology professionals globally, with significantly more in distress and feeling burnout compared with the first wave. Collective efforts from both national and international communities addressing support and coping strategies will be crucial as we recover from the COVID-19 crisis. In particular, an action plan should also be devised to tackle concerns raised regarding the negative impact of COVID-19 on career development, training, and job security. Compared with survey I, more oncology professionals were at risk of poor well-being (33% versus 25%) and burnout (49% versus 38%). Job performance since COVID-19 (JP-CV) has improved from 34% to 51%. About 1 in 5 who tested positive for COVID-19 felt they had not been given adequate time to recover before return to work. Some 39% expressed concerns that COVID-19 would have a negative impact on their career development or training. More than two-thirds revealed that COVID-19 had changed their outlook on work-personal life balance.

Abstract
Background:Systemic sclerosis (SSc) is a multisystem disease characterized by functional and structural abnormalities of small blood vessels, fibrosis of the skin and internal organs. In addition, volume reduction and shape abnormality of the hippocampus have been demonstrated in rheumatic and neurodegenerative diseases. However, the neuroanatomy of the hippocampus is complex and is not a uniform structure, consisting of subfields with distinct morphology: cornu ammonis (CA) subfields CA1–4, dentate gyrus (DG), fimbria, and adjacent subiculum and presubiculum [1].Objectives:To investigate the hippocampal subfields volumes reduction in SSc patients using MRI.Methods:In this study we included 37 SSc patients (33 women, mean age of 53.46, SD ± 12.29; range 30 - 78) and 37 healthy controls (HC) (31 women, mean age of 48.41, SD±12.20; range 29 - 80). Cognitive evaluation was performed using the Montreal Cognitive Assessment (MoCA), mood disorders were determined through Beck’s Depression (BDI) and Beck’s Anxiety Inventories (BAI). SSc patients were further assessed for clinical and laboratory SSc manifestations, disease activity (Valentini Activity Index), severity activity (Medsger Severity Index). MRI protocol consisted of: Sagittal T1-weighted images performed with a Philips 3.0T MRI scanner. MRI brain structure volumetric was done through volBrain [2]. After 48 months MRI acquisition were repeated in 26 SSc patients and 12 healthy volunteers. Statistics was performed according nature of the variable.Results:We observed a significant reduction in hippocampal subfields volumes in SSc patients when compared to controls: Total hippocampi (SSc: mean volume = 4.78 cm3; SD = 0.38; HC: mean volume = 5.01 cm3; SD = 0.38; p = 0.033). Reduction in volume of the total hippocampi was associated with Raynaud’s phenomenon (p = 0.006). A longitudinal study showed a reduction in volume of the hippocampus subfields volumes when compared to patient’s baseline: Total hippocampi (mean initial volume = 4.78 cm3; mean follow-up volume = 4.50 cm3, p = 0.027); Total CA1 (mean initial volume = 1.59 cm3; mean follow-up volume = 1.58 cm3, p < 0.0001); Reduction in volume of the total hippocampi was associated with presence of current use of prednisone (p = 0.008). Reduction in left CA1 left associated with current use of prednisone (p = 0.014). Reduction in total subiculum was associated with presence of calcinosis (p = 0.023). No significant changes were observed in hippocampal subfields volumes in controls over the follow-up period.Conclusion:This study provides evidence of hippocampus subfields volumes reductions in SSc patients when compared to controls and was associated with Raynaud’s phenomenon, current use of losartan and correlated with BAI scores. Also, a longitudinal study showed a reduction in volume of the hippocampus subfields volumes when compared to patient’s baseline associated with calcinosis and current use of prednisone.References:[1]Eichenbaum, Howard. “A cortical–hippocampal system for declarative memory.” Nature Reviews Neuroscience 1.1 (2000): 41-50.[2]Manjon JV, Coupe P (2016) volBrain: an online MRI brain volumetry system.

Abstract
Background The European Society for Medical Oncology-Magnitude of Clinical Benefit Scale (ESMO-MCBS) is a validated, widely used tool developed to score the clinical benefit from cancer medicines reported in clinical trials. ESMO-MCBS scores assume valid research methodologies and quality trial implementation. Studies incorporating flawed design, implementation, or data analysis may generate outcomes that exaggerate true benefit and are not generalisable. Failure to either indicate or penalise studies with bias undermines the intention and diminishes the integrity of ESMO-MCBS scores. This review aimed to evaluate the adequacy of the ESMO-MCBS to address bias generated by flawed design, implementation, or data analysis and identify shortcomings in need of amendment. Methods As part of a refinement of the ESMO-MCBS, we reviewed trial design, implementation, and data analysis issues that could bias the results. For each issue of concern, we reviewed the ESMO-MCBS v1.1 approach against standards derived from Helsinki guidelines for ethical human research and guidelines from the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, the Food and Drugs Administration, the European Medicines Agency, and European Network for Health Technology Assessment. Results Six design, two implementation, and two data analysis and interpretation issues were evaluated and in three, the ESMO-MCBS provided adequate protections. Seven shortcomings in the ability of the ESMO-MCBS to identify and address bias were identified. These related to (i) evaluation of the control arm, (ii) crossover issues, (iii) criteria for non-inferiority, (iv) substandard post-progression treatment, (v) post hoc subgroup findings based on biomarkers, (vi) informative censoring, and (vii) publication bias against quality-of-life data. Conclusion Interpretation of the ESMO-MCBS scores requires critical appraisal of trials to understand caveats in trial design, implementation, and data analysis that may have biased results and conclusions. These will be addressed in future iterations of the ESMO-MCBS. We reviewed trial design, implementation, and data analysis issues that could bias the results of trials. These issues could skew the results of ESMO-MCBS scores. Six design, two implementation, and two analysis issues were reviewed, and seven shortcomings were identified. These issues will be addressed in future versions of the MCBS scale. Interpretation of MCBS scores requires critical appraisal of trials.

Abstract
BACKGROUND The impact of the coronavirus disease 2019 (COVID-19) pandemic on well-being has the potential for serious negative consequences on work, home life, and patient care. The European Society for Medical Oncology (ESMO) Resilience Task Force collaboration set out to investigate well-being in oncology over time since COVID-19. METHODS Two online anonymous surveys were conducted (survey I: April/May 2020; survey II: July/August 2020). Statistical analyses were performed to examine group differences, associations, and predictors of key outcomes: (i) well-being/distress [expanded Well-being Index (eWBI; 9 items)]; (ii) burnout (1 item from eWBI); (iii) job performance since COVID-19 (JP-CV; 2 items). RESULTS Responses from survey I (1520 participants from 101 countries) indicate that COVID-19 is impacting oncology professionals; in particular, 25% of participants indicated being at risk of distress (poor well-being, eWBI ≥ 4), 38% reported feeling burnout, and 66% reported not being able to perform their job compared with the pre-COVID-19 period. Higher JP-CV was associated with better well-being and not feeling burnout (P < 0.01). Differences were seen in well-being and JP-CV between countries (P < 0.001) and were related to country COVID-19 crude mortality rate (P < 0.05). Consistent predictors of well-being, burnout, and JP-CV were psychological resilience and changes to work hours. In survey II, among 272 participants who completed both surveys, while JP-CV improved (38% versus 54%, P < 0.001), eWBI scores ≥4 and burnout rates were significantly higher compared with survey I (22% versus 31%, P = 0.01; and 35% versus 49%, P = 0.001, respectively), suggesting well-being and burnout have worsened over a 3-month period during the COVID-19 pandemic. CONCLUSION In the first and largest global survey series, COVID-19 is impacting well-being and job performance of oncology professionals. JP-CV has improved but risk of distress and burnout has increased over time. Urgent measures to address well-being and improve resilience are essential.

Abstract
BACKGROUND Mucosal melanoma is a rare malignancy which represents approximately 1% of all melanomas. It is shown that mucosal melanomas have a different biology and less favourable prognosis than its cutaneous counterpart. OBJECTIVES Predictive and prognostic factors of survival for mucosal melanoma have not yet been elucidated. The aim of this study was to investigate risk factors affecting the course of mucosal melanoma patients followed in our clinic. METHODS One hundred and sixty-one patients with mucosal melanoma prospectively documented in the German Central Malignant Melanoma Registry (CMMR) were included in this study. Gender, age, localization, stage at first medical examination, tumour thickness and mutational status were documented. The American Joint Committee on Cancer (AJCC), 7th edition was used to define tumour stage. Kaplan-Meier survival curves were evaluated compared with the log-rank test. Multivariate Cox proportional hazard models were used to identify significant independent prognostic factors. RESULTS According to the localization, patients were categorized in 44.7% oral-nasal, 28.6% genital, 20.5% anorectal and 6.2% visceral. Genital mucosal melanomas had the most favourable 5-year OS rate (58.6%) followed by visceral (58.3%) and oral-nasal (39.3%). Anorectal melanomas had the worst OS time (median: 21 ± 4.8 months) and 5-year survival rate (22.7%). Patients <60 years had a better survival than the older group (P = 0.013). Tumour stage at the time of the first medical examination was also a significant factor for survival (P = 0.001). Gender and mutational status were found to have no effect on survival. Age (<60 years vs. ≥60 years; HR = 2.1) and stage at first medical examination (Stage I vs. Stage IV; HR = 8.2) are shown to be significant independent prognostic factors on multivariate Cox regression analysis, but not localization. CONCLUSION In this study, we observed that older age and advanced stage have significant negative effects on the survival of mucosal melanoma. Thus, the AJCC staging system is applicable for mucosal melanoma.

Abstract
Understanding the signalling pathways involved with derivation of embryonic stem cells could enhance our understanding of pluripotency in pre-implantation embryos. Recently, the small molecule IWR-1 has been shown to promote derivation of mouse epiblast stem cells and pluripotent bovine and porcine embryonic stem cells (ESC). IWR-1 blocks WNT signalling mediated by β-catenin-targeted gene expression through stabilisation of Axin2, a member of the destruction complex that induces β-catenin degradation. Here, we evaluated whether dickkopf WNT signalling pathway inhibitor 1 (DKK1) can replace IWR-1 for establishment of bovine pluripotent ESC. If so, it is likely that the actions of IWR-1 to promote pluripotency involve inhibition of WNT signalling. Treatment of bovine embryos with 100ngmL−1 recombinant human DKK1 beginning at Day 5 of development decreased (P=0.02) immunofluorescent labelling of β-catenin in the resulting blastocysts (n=41-45/group), indicating that bovine embryos are responsive to DKK1 treatment. For ESC derivation, blastocysts were plated on top of feeder cells and cultured in ESC medium supplemented with 2.5 µM IWR-1 (n=21), 100ngmL−1 DKK1 (n=34), or vehicle (n=23). Cells were passaged every 5 to 7 days in their respective treatment medium. Seven days after plating, 57.9±14.7% of blastocysts in IWR-1 ESC medium developed outgrowth, which was lower (P=0.02) than the proportion of blastocysts with outgrowth in DKK1 medium (92.4±5.2%) or vehicle (81.9±10.0%). Outgrowth size did not differ among treatments. Labelling with CDX2 indicated that the majority of cells in outgrowths were trophectoderm cells. Thus, IWR-1 inhibits competence of blastocysts to form trophectoderm outgrowths during derivation of ESC. The percent of blastocysts from which cell lines were derived after 4 passages were 48% (10/21) for IWR-1, 41% (14/34) for DKK1, and 48% (11/23) for vehicle. Immunolabelling for the pluripotency marker SOX2 showed that only cells grown in IWR-1 medium were positive, whereas most of the cells derived in the other two media were not. Thus, IWR-1 could not be replaced by DKK1 for maintaining pluripotency. Immunoreactive β-catenin was abundantly distributed on the membrane of cells cultured with IWR-1 but not with DKK1 or vehicle-treated cells. Thus, β-catenin distribution to the cell membrane is linked with bovine pluripotency. Overall, results indicate that maintenance of pluripotency by IWR-1 may involve mechanisms other than WNT inhibition, and may be related to the localization of β-catenin to the plasma membrane.

Abstract
BACKGROUND It is known that melanoma can metastasize and recur many years after the first diagnosis. Although predictive and prognostic factors for melanoma are well defined, there is still insufficient information about the factors affecting the recurrence period and the effect of the recurrence time to survival. OBJECTIVES This study investigates the course of melanoma to show prognostic factors comparing early and late recurrence patients. The main objective is to uncover the effect of the recurrence time on the progression of the disease. METHODS In this retrospective study, late recurrence (LR) was defined as melanoma recurrence 10 years after the first diagnosis and early recurrence (ER) was defined as recurrence within 10 years. Gender, age, localization of primary tumour, time to first metastasis, survival rates, histological subtype, stage, tumour thickness, invasion level, ulceration and regression of the primary melanoma were documented. Survival curves were evaluated using the Kaplan-Meier and compared with the log-rank test. Multivariate Cox proportional hazard models were used to identify significant independent prognostic factors for melanoma-specific survival (MSS). RESULTS A total of 1537 melanoma patients were analysed. Early metastasis was developed in 1438 patients (93.6%), and 99 patients (6.4%) developed late metastasis. Late recurrence patients were younger (P < 0.001) and had fewer ulcerated (P = 0.005), fewer head/neck localized (P = 0.009) and thinner (P < 0.001) melanomas than ER patients. The MSS time (mean ± SD) was nearly identical for LR (31 ± 4.4 months 95% CI [22.3-39.7]) and ER (32 ± 1.9 months [28.3-35.7]). Multivariate regression analysis revealed male gender (hazard ratio [HR = 1.4, P < 0.001), truncal tumour localization (HR = 1.7, P < 0.001), tumour thickness (HR = 1.4, P < 0.045) and ulceration (HR = 1.3, P < 0.008) as significant independent prognostic factors for MSS. CONCLUSION Although ER and LR patients are found to have different clinicopathologic features, the time of the first recurrence after diagnosis do not seem to have an effect on the survival.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) is one of the most common types of cancer in the Caucasian population, with an increasing incidence. cSCC is mostly a local invasive disease that can be treated surgically in the majority of the cases. However, in the case of advanced cSCC (acSCC), a multimodality approach also involving systemic therapies needs to be considered. METHODS One hundred and ninety-five patients diagnosed with acSCC (stages III and IV) treated in our centre between 2011 and 2018 were included. Patient and tumour characteristics along with treatment patterns were documented and analyzed. Descriptive analysis was performed and survival rates were estimated according to Kaplan-Meier and compared with the Log-rank test. Follow-up was defined as the time between diagnosis of advanced disease and last contact or death. All causes of death were considered as events. RESULTS The median follow-up was 21 months [IQR = (10.0; 21.0)]. The median age at time of advanced disease diagnosis was 78 years [IQR = (72; 84)], with 40.5% of the patients in stage III and 59.5% in stage IV. One hundred and forty-five patients had resectable tumours. In this group the median overall survival (mOS) was 59 months (95% CI: 28.2-89.8), significantly higher than the mOS in patients with inoperable tumour [n = 50; mOS: 19 months (96% CI: 7-31, P <0.0001)]. Patients receiving immunotherapy (n = 20) showed a statistically significant better survival compared to those treated with other systemic therapies (n = 37; mOS not reached vs. mOS: 22 months (95% CI: 6.5-43.5), P = 0.034). For patients without systemic therapy, a combination of surgery and radiotherapy provided better outcomes compared to radiotherapy alone or best supportive care (P <0.001). CONCLUSION Surgical complete resection should be the first therapeutic option for patients with acSCC. For patients with inoperable tumour, first-line immunotherapy should be preferably considered.

Abstract
We evaluated the influence of individually estimated portion sizes on the estimate of nutrient related risk of colorectal cancer, using data from a Portuguese hospital based case-control study on diet and colorectal cancer. A total of 100 patients with colorectal adenocarcinoma (aged 15-92 years) and 211 controls (aged 36-89 years) were included. Two data sets were created for nutrient analysis, the first one allowed estimates of food intake using data on portion size as collected with visual aids during the interview. The second estimate substituted respondents' estimate with a standard portion size, as used in the semi-quantitative (SQ) food frequency approach. The two analytic approaches yielded similar energy and nutrient intakes in cases and controls. The percent range of concordance is acceptable, in the same quartile varying from 44 to 82% (mean: 56%) and very good in the same or adjacent (+/-1) quartile (mean: 91%, range: 85-97%). The two estimates lead to a similar pattern of multivariate odd's ratio, however the SQ estimates resulted in more significant findings. We conclude that little extra information is gained by including individual portion size information when assessing diet-related risk of colorectal cancer.

Abstract
Cardiac troponin-T is a subunit of the myofibrillar regulatory troponintropomiosin complex, with sufficient specificity to myocardium. In normal conditions it is absent from serum and its presence indicates lesion of the cardiac cells. The authors evaluated the analytical and clinical performance of an immunoassay for cardiac troponin-T, before its introduction in their own laboratory routine. They concluded that the test had good analytical performance, with some difficulties in practicability that can be surpassed by using a rapid bedside test for troponin-T in urgency departments, already approved by FDA in USA and available in Portugal. The diagnostic specificity and sensitivity was better than the one of the classic enzymatic markers for Acute Myocardial Infarction (AMI) but it is necessary to establish clear clinical protocols that allow its use in AMI.

Abstract
This work studied in vitro the interaction of aqueous and hydroalcoholic extracts of Valeriana officinalis L. and compounds that are present in the extracts (amino acids and valerenic acid) with the GABAA (gamma-aminobutyric acid) receptor, using the [3H] muscimol binding technique to crude synaptic membranes from rat brain cortices. Both extracts displaced [3H]muscimol bound and this effect is probably due only to their amino acid content, specially GABA. This fact explains the in vitro effect of valerian extracts on GABAA receptor but not their sedative effect.
