De Novo Experience of Individuals with Li-Fraumeni Syndrome: Sometimes the people in your family are never going to be the ones who understand best

Background/Objectives: Li-Fraumeni Syndrome (LFS) is a rare hereditary cancer predisposition syndrome characterized by high lifetime risks for multiple primary malignancies. Although most individuals with LFS inherit a pathogenic TP53 variant from a parent, approximately 20% have de novo variants with no suggestive family cancer history. This may result in an LFS experience distinct from individuals with affected relatives. This multi-case study report examines the unique psychosocial experiences of three young adults with de novo TP53 variants. Method(s): The National Cancer Institute's LFS study (NCT01443468) recruited adolescents and young adults (AYAs;aged 15-39 years) with LFS for qualitative interviews. Three participants had a de novo TP53 variant and a personal cancer history. An interprofessional team analyzed interview data using extended case study and narrative methods. Result(s): De novo participants lacked familiarity with LFS to situate a cancer diagnosis, interpret genetic test results, or adjust to chronic cancer risk. Communicating with and receiving support from family was challenged by their lack of common experience. De novo participants experienced socioemotional isolation, which was amplified during the COVID-19 pandemic. To cope, they sought support in online rare disease communities or through mental health providers. Conclusion(s): Individuals with de novo variants may lack familial guides and familiar providers to address disease management and uncertainty. Specialty health and mental health providers may support de novo patients across hereditary cancer syndromes by validating their uncertainties and connecting them with diseasespecific patient advocacy groups that support adjustment to chronic cancer risk.

Future challenges and their impact on respiratory health and lung cancer

Air pollution, climate and population health are closely related in terms of their impacts on respiratory health and lung cancer. Air pollutants contribute to the exacerbation of chronic respiratory problems such as COPD and asthma. Air pollutants are also toxic and carcinogenic, initiating and promoting lung cancer development. Climate change in relation to environmental pollution affects the geographical distribution of food supply and diseases such as pneumonia in adults and children. The threat of air pollution, and hence global warming and climate changes, and their effects on population and respiratory health, is an imminent threat to the world and deserves immediate and sustainable combating strategies and efforts. The goals are to increase public awareness and engagement in action, with alignment of international collaboration and policy, and with steering towards further research. Now is the prime time for international collaborative efforts on planning and actions to fight air pollution and climate change before it is too late.Copyright © ERS 2021.

Reducing your risk cancer-focused health events to meaningfully engage the medically underserved and diminish future cancer disparities

Lack of access to cancer prevention education, early screening, and timely treatment, particularly in low socioeconomic, underserved communities, are cited as substantial barriers to improving survivorship. Outreach educational efforts with on-site screenings offered in partnership with community groups are known to be valuable in encouraging community members' uptake of healthy behaviors and adherence to screening recommendation. To create more engaging events, a community-academic partnership, We Engage 4 Health (WE4H), co-created 11 unique 4-panel comic-style stories designed to be read aloud together as attendees visit each event table. These colorful stories are shared on boards that stand on each table and are offered in both English and Spanish at this time. Many tables also have an accompanying hands-on activity. Together, they lead to meaningful "low stakes" discussions which support understanding of seemingly complex health information. Story topics include the cause of cancer (Cells Gone Wrong), cancer risk factors (Reducing Your Risk), the role of primary care in cancer screening (Primary Care for Prevention), the purpose of research (short Research Ready) and details about specific cancer types (Combatting Colon Cancer, Blocking Breast Cancer, Looking for Lung Cancer, Silencing Skin Cancer, Hindering HPV, and Professional Prostate Protection) and COVID-19 (Take Your Best Shot FAQs). A health passport is used to facilitate table visitation and survey collection at each table enables meaningful evaluation of the event as well as provides the community hosts and their partners baseline cancer data to inform future programing. In 2022, WE4H and the University of Cincinnati Cancer Center partnered with three different communities to co-host pilot events that served over 100 adult residents. Community, research interns and university students volunteered to work the tables at the event and received training prior. Post event surveys and discussions indicated that community partners appreciated the different take on a health fair event. Most volunteers indicated that they would enjoy volunteering again. Attendees indicated that they liked the graphic-style story format used and most preferred it to text and text with graphics approaches. Taken together, the data indicates that Reducing Your Risk events are useful in meaningfully engaging hard to reach, at risk attendees. Additional in-person and virtual events are being planned for 2023 as an approach to reach the medically underserved throughout our region.

Patient Preferences for Lung Cancer Interception Therapy

Objectives: Interception therapy requires an individual to take a treatment today to prevent a future medical event. Patients must trade off treatment burdens incurred today against future benefits. We examined the preferences of high-risk lung cancer (LC) individuals for potential interception therapies that reduce the risk of developing lung cancer. Method(s): An online discrete-choice experiment (DCE) was developed for hypothetical LC interception treatments with four attributes: reduction in risk of LC over 3 years, injection site reaction severity, nonfatal serious infection risk, and death from serious infection risk. Respondents chose between two alternative treatments or a no-treatment option. The DCE was analyzed using random-parameters logit, and maximum acceptable risk for an LC risk reduction was calculated. Logit analysis explored characteristics of respondents who always selected no treatment. Result(s): The sample included 803 adults aged 50-80 years with at least a 20 pack-year smoking history. Respondents had an average willingness to accept interception therapy (alternative-specific constant=1.30, 95% CI: 0.91-1.69). Respondents viewed larger reductions in the risk of LC as most important. Respondents were willing to accept increases in risk of nonfatal serious infection up to 15% for a 15% improvement in relative LC risk reduction and increases in risk of death from serious infection up to 1.5% for a 23% improvement in relative LC risk reduction. However, 16% of respondents selected 'no treatment' for all DCE questions. Older respondents, current smokers who have never tried to quit, and those who did not get regular skin exams for cancer and/or COVID-19 vaccine were more likely to opt out of interception therapy. Conclusion(s): Generally, individuals at high risk of LC are willing to consider interception therapy. Study results can support benefit-risk assessments for future systemic LC interception treatments, and the results may have implications for other therapeutic areas.Copyright © 2023

Viruses and the risk of lung cancer: prevention and treatment

Lung cancer is the most common cancer in males and the second most common among females both in Europe and worldwide. Moreover, lung cancer is the leading cause of death due to cancer in males. The European region accounts for 23% of total cancer cases and 20% of cancer-related deaths. Relationships have been described between a number of infectious agents and cancers, but our knowledge of the role of viruses, both respiratory and systemic, in the pathogenesis of lung cancer is still rudimentary and has been poorly disseminated. In this chapter, we review the available evidence on the involvement of HPV, Epstein-Barr virus, HIV, cytomegalovirus and measles virus in the epidemiology and pathogenesis of lung cancer.Copyright © ERS 2021.

A narrative review on radiation risk from imaging for COVID-19: Breaking the myths and the mithya

Radiotherapy-induced secondary malignancy is a well-known occurrence. During the COVID-19 pandemic, many people have undergone serial computed tomography (CT) imaging, and concerns have been raised regarding radiation-induced malignancies due to frequent scanning. Accordingly, various low and ultra-low-dose CT (LDCT) thorax protocols have been developed to reduce the dose of radiation. Major governing bodies worldwide have established guidelines regarding the indications for CT scans and chest X-rays during the pandemic. We, therefore, aimed to provide facts about the effects of radiation (both diagnostic and therapeutic). Through this article, we intend to break the myths and 'mithya' (misbeliefs) regarding diagnostic radiation and its association with cancer in this COVID-19 era. For this review, we performed a search in Google using specific keywords pertaining to imaging during COVID-19 and radiation risk. We also included the names of various global governing bodies in the Google search. We included only full text articles and guidelines from authentic websites. From this review, we conclude that if we follow the recommendations of various global governing bodies and use CT scan only in cases of moderate to severe COVID-related symptoms, adhere to the principle of 'as low as reasonably achievable' for radiation protection, and use LDCT scan protocols, we can significantly reduce the mean effective radiation dose delivered and the estimated cancer risk.Copyright © 2023 Cancer Research, Statistics, and Treatment.

Community outreach and engagement to increase colorectal cancer screening in ethnic minority communities

PURPOSE: Colorectal cancer (CRC) is preventable with screening, yet remains the second leading cause of cancer deaths in the U.S. Nationally, CRC screening substantially declined during the COVID-19 pandemic and is underutilized by ethnic minorities and in safety-net systems. Therefore, City of Hope partnered with Federally Qualified Health Centers (FQHCs) and community and faithbased organizations to improve CRC screening among medically underserved communities. METHOD(S): Between October 2020 and October 2022, we implemented a multi-component intervention that included community outreach and education (a multi-ethnic multimedia campaign and community training adapted from the NCI Screen2Save (S2S) program) and clinic-based interventions (provider/staff training and patient education). Intervention reach and training participant surveys were assessed. Within our four FQHC sites, we also compared clinic-level CRC screening rates among age-eligible patients before (June 2021) and after implementation of the clinic-based intervention (June 2022). RESULT(S): Our reach assessment showed that our multi-ethnic multimedia campaign reached 35.4 million impressions, our S2S education training reached 300 diverse community members, and our provider/staff training reached 150 medical providers. Among the 100 providers surveyed, >80% felt confident they could get their patients to complete their CRC screening test and follow-up care. For the clinic-based intervention component, our baseline sample included 11,259 age-eligible patients across the four FQHC sites. Overall CRC screening rates increased from 45% to 52% before vs. after the intervention implementation period. The site with the highest CRC screening rate (>62%) maintained steady rates over the observation period, whereas three sites with lower baseline rates showed greater pre-post improvements (average 15 percentage-point increase). CONCLUSION(S): An overall increase in CRC screening rates was achieved across FQHCs, despite clinic staffing challenges during the COVID-19 pandemic. Intervention implementation is ongoing with attempts to document individual, clinic improvements by race/ethnicity.

Coronavirus infection and organizational changes in the clinical process in patients with non-muscle-invasive bladder carcinoma.

The spread of the aggressive disease caused by the novel respiratory syndrome coronavirus-2 (SARS-CoV-2) has had an impact not only on the health and psyche of people, but also on the state of health systems in different countries, by complicating the treatment and diagnostic process. These changes have affected patients with cancers to a greater extent. The diagnosis, treatment, and follow-up of patients are of particular scientific and practical interest when working in conditions of special anti-epidemic control. Objective. To assess the possibility of reducing the frequency of hospitalization of patients with non-muscle-invasive bladder carcinoma (NMIBC) during the Covid-19 period. Subjects and methods. Sixty-four patients with urinary tract malignancy, including 19 (29.7%) patients with low-and high-risk re-current NMIBC, were followed up in two clinics (Saint Petersburg, Russia) in March to October 2020. All the patients were oper-ated on;the patients at high risk for recurrence received a cycle of adjuvant BCG therapy. Methods for cytological examination of urine sediment and the biomarkers UBC and Cyfra 21-1 were used for special laboratory diagnosis;the server stations of both clinics were applied for telehealth consultations (TCs). Results. TCs were used to reduce hospitalization rates: after TCs, all the patients reported a reduction in transport costs and recovery time after hospitalization. TCs could protect the followed-up patients against COVID-19 infection, by observing the rules of clinical examination, and achieve maximum individualization of treatment. The authors refused to perform diagnostic operations for low-risk NMIBC and to use laboratory tests using urinary biomarkers. At the place of their residence, outpatients underwent urinalysis for several indicators, transmitting the result to the clinic's servers or through a monitoring system. Inpatient treatment was used only in cases of gross hematuria or after recording abnormal laboratory test results. Control cystoscopy detected no re-current tumor. Conclusion. During the spread of COVID-19, the periods of endoscopic examinations and control diagnostic operations can be post-poned, by replacing face-to-face consultations with TC monitoring. Outpatient laboratory and radiation examinations are indicat-ed in patients with new-onset gross hematuria or after combination treatment. Repeated operations, including diagnostic ones, should be performed in the case of multiple NMIBCs or after incomplete excision of the primary tumor.Copyright © 2021.

Developing a comorbidity score in cancer patients using healthcare utilization databases during the COVID-19 pandemic: An experience from Italy.

BACKGROUND: A strong relationship has been observed between comorbidities and the risk of severe/fatal COVID-19 manifestations, but no score is available to evaluate their association in cancer patients. To make up for this lacuna, we aimed to develop a comorbidity score for cancer patients, based on the Lombardy Region healthcare databases. METHODS: We used hospital discharge records to identify patients with a new diagnosis of solid cancer between February and December 2019; 61 comorbidities were retrieved within 2 years before cancer diagnosis. This cohort was split into training and validation sets. In the training set, we used a LASSO-logistic model to identify comorbidities associated with the risk of developing a severe/fatal form of COVID-19 during the first pandemic wave (March-May 2020). We used a logistic model to estimate comorbidity score weights and then we divided the score into five classes (<=-1, 0, 1, 2-4, >=5). In the validation set, we assessed score performance by areas under the receiver operating characteristic curve (AUC) and calibration plots. We repeated the process on second pandemic wave (October-December 2020) data. RESULTS: We identified 55,425 patients with an incident solid cancer. We selected 21 comorbidities as independent predictors. The first four score classes showed similar probability of experiencing the outcome (0.2% to 0.5%), while the last showed a probability equal to 5.8%. The score performed well in both the first and second pandemic waves: AUC 0.85 and 0.82, respectively. Our results were robust for major cancer sites too (i.e., colorectal, lung, female breast, and prostate). CONCLUSIONS: We developed a high performance comorbidity score for cancer patients and COVID-19. Being based on administrative databases, this score will be useful for adjusting for comorbidity confounding in epidemiological studies on COVID-19 and cancer impact.

IMPORTANCE OF COMPREHENSIVE HEALTH RISK ASSESSMENT PROCEDURES FOR MODERN WASTE-TO-ENERGY FACILITIES IN COMPLEX GEOGRAPHICAL CONTEXTS ORIENTED TO CIRCULAR ECONOMY

Although circular economy (CE) principles set material circularity, resource efficiency and waste recycling as priority targets to guarantee the sustainable development of future generations, the thermochemical valorisation of municipal solid waste (MSW) still plays a fundamental role in the transition towards the final CE targets. As a matter of fact, the waste-to-energy (WtE) sector allows recovering energy from waste, reducing the pressure on MSW landfills and their related potential environmental impacts;however, recovering material for further uses is not excluded in WtE options. Significant improvements have been achieved in the air pollution control of exhaust gases from direct and indirect MSW combustion during the last decades. The efforts focussed on reducing dioxin emissions especially, and this has let other substances emerge as priority pollutants (e.g., heavy metals). In addition, the location of WtE facilities in certain geographical contexts is still potentially critical from the point of view of human exposure and the related health risk;moreover, the public acceptance of WtE plants is still limited, in spite of their recent role in fighting SARS-CoV-2 risks from waste management. The purpose of the present paper is to underline the importance of implementing correct and complete health risk assessment procedures tailored to the exposed population living in the area of influence of a WtE plant. The paper will present two case studies regarding the projects of two WtE plants in a mountainous region, highlighting the critical issues that arose during the environmental impact assessment procedures. The paper will finally suggest possible options to improve the health risk assessment procedure and alternative measures to reduce the expected impacts of the WtE sector on the environment and human exposure. © 2022 WIT Press.

Impact of vaccination against SARS-CoV-2 on the risk of hospital admission and death among infected patients with urologic cancers: A population-based study in northern Italy

Background: Hospital admission and death of infected cancer patients were investigated according to SARS-CoV-2 vaccination status. Method(s): Population-based observational study on 1874 SARS-CoV-2 infected patients with prostate (n=1276), kidney (n=327), and bladder (n=271) cancers. Hazard ratios (HR) and their 95% confidence intervals (CI), adjusted for sex and age, were computed to assess the risk of hospital admission and death of unvaccinated patients as compared to vaccinated ones. Result(s): 24.5% of patients with prostate, 26.9%with kidney and 29.5%with bladder cancer were unvaccinated. As compared to vaccinated ones, a statistically significant excess risk of hospital admission emerged for unvaccinated ones with prostate (HR=3.33, 95% CI: 2.50-4.55), and kidney (HR=4.35, 95% CI: 2.33-8.33) cancer. The 312 unvaccinated prostate cancer patients were also at a nearly 3-fold higher risk of death than vaccinated ones (HR=2.98, 95% CI:1.89-4.70). Conclusion(s): Study findings stress the importance of SARS-CoV-2 vaccines in reducing hospital admission and death in patients with urologic cancers, particularly prostate cancer.

Changes in preferences for ovarian cancer prevention strategies during the COVID-19 pandemic: Results of a discrete choice experiment

Background: The COVID-19 pandemic influenced patient health care decisions, but there is little information about the pandemic's impact on decisions about cancer risk reduction. This includes women at elevated risk of breast or ovarian cancer considering risk-reducing salpingooophorectomy (RRSO), risk-reducing salpingectomy (RRS), or other preventive measures. During the pandemic patients needed to balance their concerns about cancer risk reduction with their risks associated with elective health procedures, a risk which changed as vaccines became available. Method(s): To address the impact of the COVID-19 pandemic on cancer prevention decision making, we recruited N=396 pre-menopausal women with a personal history of breast cancer or familial history suggestive of increased breast and/or ovarian cancer risk between 4/2019 and 3/2022. We conducted a discrete choice experiment in which patients were asked to choose between two scenarios that specified type of surgery (RRSO, RRS vs. non-surgical surveillance), age of menopause (natural versus immediate), quality of menopausal symptoms (mild, moderate, severe), and risk of ovarian cancer, heart disease, or osteoporosis. Risk of ovarian cancer for the scenarios provided varied in discrete intervals from 0% to 40%. We examined temporal trends during the pandemic using interactions with time coinciding approximately with the beginning of pandemic, peak vaccination period, and the Omicron wave. Result(s): We identified significant temporal interactions on a woman's prevention decisions. In 2019, women at higher risk of ovarian cancer were more likely to choose prevention scenarios that favored lower ovarian cancer risk (odds ratio [OR] = 0.48;95% CI = 0.37, 0.69 per 10% increase in ovarian cancer risk difference). This association decreased through the pre-vaccine period of 2020 by OR=2.61/month (95% CI = 1.21, 5.65). By June 2020, the effect of a 10% increase in ovarian cancer risk on intervention choice had attenuated substantially (OR=0.84, 95% CI 0.67, 1.00). By January 2022, the effect strengthened (OR= 0.69, 95% CI .49, .88), but had not reached pre-pandemic levels. Before 3/2020, natural age of menopause (versus immediate) had a strong impact on the choice of a scenario (OR=3.56, 95% CI 1.65-7.65). At the beginning of the pandemic, the effect was reduced by 0.47/month (95% CI 0.22-0.99). The rate of attenuation slowed over time, such that the effect of having a natural age of menopause on choice was OR= 1.56 (95% CI 0.65, 2.46) by January 2022. Tests for temporal interactions were statistically significant for both ovarian cancer risk and age of menopause. Conclusion(s): Our results suggest that over the course of the pandemic, women seemed more accepting of higher risks of ovarian cancer and immediate (post treatment) menopause when considering preventive options. There was an inverse U shape curve of the effect of ovarian cancer risk on choices over time (Figure A), but the strength of the relationship had not reached prepandemic levels by January 2022. This may reflect patient tolerance for side effects as the pandemic evolved. These results suggest that factors such as ovarian cancer risk and delay of menopause influenced personal prevention choices, but that these choices were influenced by events related to events that hallmarked the COVID-19 pandemic.

Temporary reduction in VOCs associated with health risk during and after COVID-19 in Maharashtra, India.

A novel coronavirus has affected almost all countries and impacted the economy, environment, and social life. The short-term impact on the environment and human health needs attention to correlate the Volatile organic compounds (VOCs) and health assessment for pre-, during, and post lockdowns. Therefore, the current study demonstrates VOC changes and their effect on air quality during the lockdown. The findings of result, the levels of the mean for total VOC concentrations were found to be 15.45 ± 21.07, 2.48 ± 1.61, 19.25 ± 28.91 µg/m3 for all monitoring stations for pre-, during, and post lockdown periods. The highest value of TVOCs was observed at Thane, considered an industrial region (petroleum refinery), and the lowest at Bandra, which was considered a residential region, respectively. The VOC levels drastically decreased by 52%, 89%, 80%, and 97% for benzene, toluene, ethylbenzene, and m-xylene, respectively, during the lockdown period compared to the previous year. In the present study, the T/B ratio was found lower in the lockdown period as compared to the pre-lockdown period. This can be attributed to the complete closure of non-traffic sources such as industries and factories during the lockdown. The Lifetime Cancer Risk values for all monitoring stations for benzene for pre-and-post lockdown periods were higher than the prescribed value, except during the lockdown period.

Quality of life indicators including mental health factors in CaPTC prostate cancer familial cohort study of men of African Ancestry in Nigeria, Cameroon, and United States

INTRODUCTION The Prostate Cancer Transatlantic Consortium (CaPTC) has the goal of better understanding the burden of prostate cancer among Black men of West African descent. While prostate cancer disproportionately affects Blacks around the world, little research is done to understand what mental health and social support play a role in prostate cancer risk factors. The purpose of this 10-year longitudinal study is to establish a cohort of U.S.-born Black men, West African-born Black men who reside in the U.S, and West African Black men in Africa who would be prospectively and longitudinally followed to better understand the cause of prostate cancer and how different factors might influence it. METHODS Study staff partnered with community-based organizations, events, and stakeholders to engage with the priority population. Snowball sampling was also used for recruitment. All participants were made aware of the longitudinal nature of the study and that they would be contacted every two years for follow-up. Informed consent was done in community settings electronically and on paper. Once consent was received, participants completed the survey with a unique identifier and filled out a Cohort Contact sheet. They were given the option to complete this on their own or with the help of the study staff. Study Staff would then measure participants' weight, height, and waistline, to be recorded on the survey form. After this, participant saliva was collected and tracked with the unique identifier. All collected data was stored on RedCap and a Chi-squared test was utilized to identify statistical significance. RESULTS 803 participants are included in this data with 77 in Cameroon, 663 in Nigeria, and 59 in the United States. When asked about emotional support, 13.6% (US) 11.8% (Nigeria), and 14.3% (Cameroon) indicated never or rarely having emotional support. 5.8% of those in the United States, 5.6% of those in Nigeria, and 7.8% of those in Cameroon felt dissatisfied or very dissatisfied with their lives. The p-value for both was found to be <0.001, therefore, suggesting statistical significance. On the other hand, participants described having an average of 6.53 (US), 9.4 (Nigeria), and 8.26% (Cameroon) days where their mental health was not good. However, this was statistically insignificant with a p-value of .95. CONCLUSION Mental health issues have been on the rise since the COVID-19 pandemic. While many people of color have stigmatized needing mental health help, it is important to find ways to overcome this barrier in assessing mental health and social support needs. Future research should continue to ask mental health and social support questions in order to assess their role in prostate cancer risk factors.

Cancer, Covid and Control of Ra - a Toxic Combination?

Case report - Introduction: This case highlights the dilemma of keeping rheumatoid arthritis disease under control in active cancer cases and establishing a consistent multidisciplinary dialogue during a pandemic and staffing crises. During chemotherapy and active cancer treatment, disease-modifying therapies (conventional and biologic) are often stopped. In some cases, the potential benefits versus risks of restarting usual therapies have to be balanced against risks of suppressing disease activity with highdose steroids. Risks of infection (common and atypical) need to be considered. Case report - Case description: A is a 67-year-old female nonsmoker diagnosed with seropositive rheumatoid arthritis (RF, anti - CCP positive) in 2008. Other conditions include type 2 diabetes, atrial fibrillation (on warfarin), hypothyroidism and obstructive sleep apnoea. Due to active disease, despite triple therapy (methotrexate, sulphasalazine and hydroxychloroquine), anti-TNF therapy (etanercept) commenced in 2009 with primary non-response. However, she responded well to B-cell therapy (rituximab) in conjunction with oral methotrexate (25mg weekly) receiving annual infusions from 2010 to 2016. In 2017, an elective sleeve gastrectomy procedure for high BMI was abandoned after peritoneal deposits of concern were noted. Histology and CT imaging were consistent with a primary peritoneal malignancy (Stage 3c low-grade serous adenocarcinoma). Treatment involved debulking surgery (total abdominal hysterectomy, bilateral salpinoophorectomy, omentectomy) and tamoxifen. Treatment for rheumatoid arthritis stalled during this period but as frequent steroids were required for active joint inflammation, in agreement with the oncologists, she had a rituximab cycle in 2018. Unfortunately, in 2019 she had signs of cancer progression (elevated tumour markers, CT imaging) and has subsequently started carboplatin chemotherapy. She has been unable to continue methotrexate or rituximab pending completion of the chemotherapy cycles (ongoing). However, her arthritis is now uncontrolled without increased steroids. Due to recurrent flares, her maintenance dose has been increased from 5mg to 7.5-10mg prednisolone daily until we can establish if it is safe and appropriate to recommence her usual arthritis regime. Even without disease-modifying therapy like methotrexate and rituximab, risk of infection (including atypical ones) is still significant with the combination of chemotherapy and steroids. Risk of progressive joint damage and adverse quality of life with active arthritis also needs to be considered. Staffing crises, exacerbated by COVID pandemic issues, have added to complexity of decision making and coordination of regular multidisciplinary discussions regarding treatment. Case report - Discussion: Cancer is a known association in rheumatoid arthritis patients with a twofold higher risk of lymphoma compared to the general population. Whether condition or treatment affects risk remains unclear as immune dysregulation is relevant in both autoimmunity and cancer. Paraneoplastic, recent onset arthritis, chemotherapy- or immunotherapy-induced arthralgia/arthritis are also well documented. This case had a seropositive rheumatoid arthritis phenotype quite a few years prior to cancer diagnosis. Primary peritoneal cancer is uncommon, often presenting as in this case as an incidental finding. It is usually treated like ovarian cancer Whilst methotrexate has been implicated in lung cancer, melanoma and non-Hodgkin lymphoma, overall safety data suggest any risk is quite low (e.g., EBV-associated lymphoproliferative disorders usually resolve with drug discontinuation). It is also a known chemotherapeutic agent. Anti-TNF treatment algorithms generally exclude patients with recent cancer. Rituximab, originally developed as a cancer drug, is not thought to affect risk of cancer development or progression. Treatment with disease-modifying therapy (conventional and biologics) is often withheld in patients with active malignancy undergoing chemotherapy due to a theo etical risk of potentiated immunosuppression and toxicity, particularly cytopaenias. However, maintaining arthritis control with glucocorticoids also has short- and long-term risks. Combining chemotherapy agents like carboplatin with methotrexate has been used for urothelial carcinoma and can be well tolerated with close monitoring of haematological parameters. Thus, it could be argued this patient is at risk of infections whichever treatment approach is taken and regaining control of arthritis with recommencement of methotrexate and rituximab is much better for her quality of life. Regular multidisciplinary discussions are important to outline risks versus benefits of combined treatment. This may be difficult in practice during staffing crises. Covid risk in patients receiving rituximab and/or chemotherapy, timing and response to COVID vaccination are also important considerations. Case report - Key learning points: . Primary peritoneal cancer is uncommon and can present as an incidental finding . Whilst treatment for progressive cancer is important, withholding rheumatoid arthritis treatment can have a significant adverse impact on quality of life . Morbidity and mortality risks of stopping treatment versus combined treatment (cancer therapy and disease-modifying therapy) ideally needs to be fully discussed and agreed with the patient and all care providers - lack of "named" providers, restructuring, redeployment, multi-specialty care and a global pandemic can make coordination of this difficult.

Low-dose radiotherapy for COVID-19 pneumonia and cancer: summary of a recent symposium and future perspectives.

The lessons learned from the Coronavirus Disease 2019 (COVID-19) pandemic are numerous. Low dose radiotherapy (LDRT) was used in the pre-antibiotic era as treatment for bacterially/virally associated pneumonia. Motivated in part by these historic clinical and radiobiological data, LDRT for treatment of COVID-19-associated pneumonia was proposed in early 2020. Although there is a large body of epidemiological and experimental data pointing to effects such as cancer at low doses, there is some evidence of beneficial health effects at low doses. It has been hypothesized that low dose radiation could be combined with immune checkpoint therapy to treat cancer. We shall review here some of these old radiobiological and epidemiological data, as well as the newer data on low dose radiation and stimulated immune response and other relevant emerging data. The paper includes a summary of several oral presentations given in a Symposium on "Low dose RT for COVID and other inflammatory diseases" as part of the 67th Annual Meeting of the Radiation Research Society, held virtually 3-6 October 2021.

Use of Quantitative Faecal Immunochemical Test (Qfit) as a Prioritization Tool in Investigation of Colorectal-Cancer Suspected Referrals during Covid-19 Pandemic in Nhs Ayrshire and Arran Hospitals

Aim: British Society of Gastroenterology advised reduced level of endoscopic services due to COVID-19 pandemic. This resulted in a significant rise in number of cancer suspected patients waiting for colonoscopy. Quantitative Faecal Immunochemical Test(QFIT)is designed to detect occult blood in stool(0 to 400 ug/g). The value of QFIT is proportional to cancer risk. Therefore, it can be utilised to prioritize cancer suspected referrals prior to colonoscopy. In this audit of service we investigated:1)The reliability of QFIT as prioritization tool for colorectal cancer referrals.2)To investigate the impact of QFIT on colonoscopy burden. Method(s): QFIT was applied to all colorectal cancer suspected referrals to NHS Ayrshire & Arran in September 2020. An interim audit of the outcome was performed focusing on four months' worth of data. QFIT values recorded and subsequent management steps analysed in following categories. QFIT less than 10,10 to 400, and over 400. The highest risk of cancer is within over 400. Result(s): 1258 test kits were dispatched,823(65%)results obtained. QFIT values were as following:631 samples with < 10(77%)of returned samples;of these 490 patients were discharged,27 patients' tests was repeated, and 114 patients were planned for further endoscopic or imaging investigations.143 patients had levels between 10 to 400. The main finding was that 49(6%)patients had QFIT more than 400, and were booked for colonoscopy. Nine patients had a confirmed cancer diagnosis. Conclusion(s): In our cohort,9 patients with QFIT more than 400 were diagnosed with cancer at colonoscopy. This is in concordance with published data reporting similer values. This would re-affirm reliability of QFIT as a prioritisation tool in predicting colorectal cancer. Majority of QFIT less than 10 were discharged following clinic consultation. This resulted in significant reduction of colonoscopy numbers that would have otherwise been performed. Longer term review of all QFIT categories is necessary to advise on its usefulness, out width the pandemic.
