RESUMO

Immune checkpoint inhibitors (ICIs) became a treatment option in most tumor types and improved survival in patients with cancer in the last decade. Older patients with cancer are underrepresented in the pivotal clinical trials with ICIs. Older patients with cancer often have significant comorbidities and geriatric syndromes like frailty, which can complicate cancer care and treatment decisions. Frailty is among the most prevalent geriatric syndromes in patients with cancer and could lead to inferior survival and a higher risk of complications in patients treated with chemotherapy. However, the effect of frailty on the efficacy and safety of ICIs is understudied. This review focuses on the available evidence regarding the association between frailty and ICI efficacy and safety. Although the survival benefits of ICIs have generally been shown to be independent of age, the available real-world data has generally suggested higher rates of immune-related adverse events (irAEs) and treatment discontinuation in older patients. While international organizations recommend conducting a comprehensive geriatric assessment CGA to assess and address frailty before the start of anti-cancer therapies, an Eastern Cooperative Oncology Group (ECOG) performance status of 2 or higher is frequently used in clinical practice as synonymous with frailty, albeit with significant limitations. The available data has generally demonstrated diminished ICI efficacy in patients with an ECOG 2 or higher compared to patients with better performance status, while the incidence of high-grade irAEs were similar. Whilst evidence regarding outcomes with ICI in older patients and in those with sub-optimal performance status is growing, there is very limited data specifically evaluating the role of frailty with ICIs. These studies found a shortened overall survival, yet no evidence of a lower response rate to ICIs. These patients experienced more AEs, but they did not necessarily have a higher incidence of irAEs.

RESUMO

Cancer is a disease associated with ageing. Managing cancer in older adults may prove challenging owing to pre-existing frailty, comorbidity, and wider holistic needs, as well as the unclear benefits and harms of standard treatment options. With the ongoing advances in oncology and the increasing complexity of treating older adults with cancer, the geriatric oncology field must be a priority for healthcare systems in education, research, and clinical practice. However, geriatric oncology is currently not formally taught in undergraduate education or postgraduate training programmes in the United Kingdom (UK). In this commentary, we outline the landscape of geriatric oncology undergraduate education and postgraduate training for UK doctors. We highlight current challenges and opportunities and provide practical recommendations for better preparing the medical workforce to meet the needs of the growing population of older adults with cancer. This includes key outcomes to be considered for inclusion within undergraduate and postgraduate curricula.

RESUMO

Development of high-performance and highly selective NIR photodetectors (PDs) using wide band gap semiconductors is a significant field of research in the present scenario. Herein, cost effective and easy fabrication of NIR PDs is demonstrated by employing the thin films of Cd1-xMgxS (x = 0, 0.01, 0.02, 0.03, 0.04 and 0.05) colloidal quantum dots (CQDs). The influence of doping on the transport behaviour of Cd1-xMgxS CQD films was investigated by device performance under laser light illumination at various wavelengths ranging from 405 nm to 782 nm. An improvement in the photoresponsivity of the material (CdS) beyond its intrinsic absorption spectral range due to the incorporation of the dopant is noticed. In spite of the cost effective and easy fabrication process without the requirement of any rigorous synthesis procedure, the devices presented here demonstrate competitive figures of merit to those that are designed with complex structures and tedious procedures. The performance parameters viz response time, responsivity, photosensitivity, quantum efficiency, and specific detectivity were improved as a consequence of Mg doping and attained a maximum value of 110 ms, ∼26.9 A W-1, ∼4.7 × 104%, ∼41.23% and ∼3.45 × 1013 Jones, respectively. Besides, the sensing range of the PDs can be tuned from visible (650 nm) to NIR (782 nm) with a huge improvement in selectivity by incorporation of Mg.

RESUMO

BACKGROUND: National cancer strategy calls for comprehensive assessments for older people but current practice across the United Kingdom is not well described. AIM: To identify current assessment methods and access to relevant supporting services for older people with cancer. METHODS: A web-based survey (SurveyMonkey) targeting health professionals (oncologists, cancer surgeons, geriatricians, nurses and allied health professionals) was distributed January-April 2016 via United Kingdom nationally recognised professional societies. Responses were analysed in frequencies and percentages. Chi Square was used to compare differences in responses between different groups. RESULTS: 640 health care professionals responded. Only 14.1% often/always involved geriatricians and 52.0% often/always involved general practitioners in assessments. When wider assessments were used, they always/often influenced decision-making (40.5%) or at least sometimes (34.1%). But 30.5%-44.3% did not use structured assessment methods. Most clinicians favoured clinical history taking. Few used scoring tools and few wished to use them in the future. Most had urgent access to palliative care but only a minority had urgent access to other key supporting professionals (e.g. geriatricians, social workers, psychiatry). 69.6% were interested in developing Geriatric Oncology services with geriatricians. CONCLUSION: There is variability in assessment methods for older people with cancer across the United Kingdom and variation in perceived access to supporting services. Clinical history taking was preferred to scoring systems. Fostering closer links with geriatricians appears supported.

RESUMO

OBJECTIVES: Older women are increasingly undergoing surgery for gynaecological malignancies. Although survival data is available other outcomes such as functional recovery are less well described. This systematic review and narrative synthesis describes functional recovery after gynaeoncology surgery with respect to baseline characteristics. MATERIALS AND METHODS: Systematic search of MEDLINE and EMBASE databases and Cochrane Library between 1974 to 2018. Two reviewers independently reviewed abstracts/papers for inclusion against the following criteria: Results analysed and presented using narrative synthesis. RESULTS: Fifteen studies identified (8 Endometrial, 2 Ovarian, 2 Vulval, 3 mixed cancer types). 1/15 used a standalone functional assessment tool, 14/15 used Health-Related Quality of Life tools (EORTC QLQ C30 (8), FACT-G (3), SF-36 (3)) comprising items describing function. More studies showed full recovery to baseline (n = 13) than incomplete recovery (n = 2). Four studies reported a negative association between older age and functional trajectory. Recovery was more likely and occurred faster in minimally-invasive surgery. Few studies reported baseline characteristics including cognition, frailty or comorbidities and none examined associations with functional recovery. CONCLUSION: There is inadequate data on functional recovery of older women following gynaeoncology surgery. Future studies are needed to identify factors associated with poorer/better outcomes. This may enable identification of opportunities for risk reduction, improve equity of access and better shared-decision making.

RESUMO

The ageing population poses new challenges globally. Cancer care for older patients is one of these challenges, and it has a significant impact on societies. In the United Kingdom (UK), as the number of older cancer patients increases, the management of this group has become part of daily practice for most oncology teams in every geographical area. Older cancer patients are at a higher risk of both under- and over-treatment. Therefore, the assessment of a patient's biological age and effective organ functional reserve becomes paramount. This may then guide treatment decisions by better estimating a prognosis and the risk-to-benefit ratio of a given therapy to anticipate and mitigate against potential toxicities/difficulties. Moreover, older cancer patients are often affected by geriatric syndromes and other issues that impact their overall health, function and quality of life. Comprehensive geriatric assessments offer an opportunity to identify and address health problems which may then optimise one's fitness and well-being. Whilst it is widely accepted that older cancer patients may benefit from such an approach, resources are often scarce, and access to dedicated services and research remains limited to specific centres across the UK. The aim of this project is to map the current services and projects in the UK to learn from each other and shape the future direction of care of older patients with cancer.

RESUMO

The incidence of most gynaecological malignancies rises significantly with increasing age. With an ageing population, the proportion of women over the age of 65 with cancer is expected to rise substantially over the next decade. Unfortunately, survival outcomes are much poorer in older patients and evidence suggests that older women with gynaecological cancers are less likely to receive current standard of care treatment options. Despite this, older women are under-represented in practice changing clinical studies. The evidence for efficacy and tolerability is therefore extrapolated from a younger; often more fit population and applied to in every day clinical practice to older patients with co-morbidities. There has been significant progress in the development of geriatric assessment in oncology to predict treatment outcomes and tolerability however there is still no clear evidence that undertaking a geriatric assessment improves patient outcomes. Clinical trials focusing on treating older patients are urgently required. In this review, we discuss the evidence for treatment of gynaecological cancers as well as methods of assessing older patients for therapy. Potential biomarkers of ageing are also summarised.

RESUMO

A 29-year-old lady presented with an increasingly swollen tongue 3 days after commencing oseltamivir (Tamiflu) for flu-like symptoms. Once identified as the cause, her symptoms rapidly improved with antihistamines and discontinuing the Tamiflu. The authors find only one other case in the literature reporting this very rare side effect.
