The experience of surgical cancer patients during the COVID-19 pandemic at a large cancer centre in London

BACKGROUND

The COVID-19 pandemic has had an enormous impact on the experiences of patients across all health disciplines, especially those of cancer patients. The study aimed to understand the experiences of cancer patients who underwent surgery during the first two waves of the pandemic at Guy's Cancer Centre, which is a large tertiary cancer centre in London.

METHODS

A mixed-methods approach was adopted for this study. Firstly, a survey was co-designed by the research team and a patient study group. Patients who underwent surgery during the COVID-19 pandemic were invited to take part in this survey. Results were analysed descriptively. Three discussion groups were then conducted to focus on the main themes from the survey findings: communication, COVID-19 risk management and overall experience. These discussion groups were transcribed verbatim and underwent a thematic analysis using the NVivo software package.

RESULTS

Out of 1657 patients invited, a total of 250 (15%) participants took part in the survey with a mean age of 66 (SD 12.8) and 52% females. The sample was representative of a wide range of tumour sites and was reflective of those invited to take part. Overall, the experience of the cancer patients was positive. They felt that the safety protocols implemented at the hospital were effective. Communication was considered key, and patients were receptive to a change in the mode of communication from in-person to virtual.

CONCLUSIONS

Despite the immense challenges faced by our Cancer Centre, patients undergoing surgery during the first two waves of the COVID-19 pandemic had a generally positive experience with minimal disruptions to their planned surgery and ongoing care. Together with the COVID-19 safety precautions, effective communication between the clinical teams and the patients helped the overall patient experience during their surgical treatment.

Assessing the quality of patient-reported outcome measurements for gynecological cancers: a systematic review

Purpose: To provide perspective on patient-reported outcome measurement (PROM) instruments to adopt in patients diagnosed with gynecological cancers. Methods: A systematic search was conducted to identify PROMs developed for or applied in gynecological cancer populations. PROMs identified in more than one study subsequently underwent assessment according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. Results: Overall, 55 PROMs were identified within the gynecological cancer setting, and 20 were assessed according to COSMIN guidelines. Most PROMs had limited information reported, but a best fit approach was adopted to recommend a number of instruments for use in patients with gynecological cancer. Conclusion: Further study to assess the methodological quality of each PROM utilized in gynecological cancers is warranted to endorse the recommendations of this review.

Cancer care for Ukrainian refugees: Strategic impact assessments in the early days of the conflict

BACKGROUND

The invasion of Ukraine by Russia in February 2022 has resulted in destruction of healthcare infrastructure and triggered the largest wave of internally displaced populations and refugees since World War Two. Conflicts in transitioned countries such as Ukraine create new non-communicable disease (NCD) challenges, especially for cancer care for refugees and humanitarian assistance in host countries. In the early days, rapid attempts were made to model possible impacts.

METHODS

By evaluating open source intelligence used in the first three months of the conflict through snowball search methods, we aimed to address: (i) burden of cancer in Ukrainian population, specifically considering translating to the refugees population, and its cancer care capacity; ii) baseline capacity/strengths of cancer systems in initial host countries. Moreover, using a baseline scenario based on crude cancer incidence in Ukraine, and considering data from UNHCR, we estimated how cancer cases would be distributed across host countries. Finally, a surveillance assessment instrument was created, intersecting health system's capacity and influx of internally displaced populations and refugees.

FINDINGS AND CONCLUSIONS

The total new cancer patients per month in pre-conflict Ukraine was estimated as 13,106, of which < 1 % are paediatric cases. The estimated cancer cases in the refugee population (combining prevalent and incident), assuming 7.5 million refugees by July 2022 and a female:male ratio of 9:1, was 33,121 individuals (Poland: 19284; Hungary: 3484; Moldova: 2651; Slovakia: 2421; Romania: 5281). According to our assessments, Poland is the only neighbouring country classified as green/yellow for cancer capacity, i.e. sufficient ablility to absorb additional burden into national health system; Slovakia we graded as yellow, Hungary and Romania as yellow/red and Moldova as red.

Is There a Role for Exercise When Treating Patients with Cancer with Immune Checkpoint Inhibitors? A Scoping Review

The impact of using exercise as a non-pharmacological intervention in patients with cancer receiving immune checkpoint inhibitors (ICIs) is not well known. Our objective was to determine the extent of, and identify gaps within, available literature addressing the effect of exercise on (a) oncological outcomes and (b) quality of life (QoL) in patients with cancer receiving ICIs, and (c) the underlying biological mechanisms for such effects. We conducted searches across EMBASE, APA PsycInfo and Ovid MEDLINE(R). Studies were eligible if they addressed at least one aspect of the objective and were available in the English language. Results were synthesised using a narrative approach and subsequently discussed with multidisciplinary stakeholders. As of the final search on 5 April 2022, 11 eligible studies were identified, of which 8 were preclinical and 3 were clinical. Clinical studies only focused on QoL-related outcomes. When studies were grouped by whether they addressed oncological outcomes (n = 7), QoL (n = 5) or biological mechanisms (n = 7), they were found to be heterogeneous in methodology and findings. Additional evidence, particularly in the clinical setting, is required before robust recommendations about whether, and how, to include exercise alongside ICI treatment can be made.

Cancer staff in an NHS cancer center: infections, vaccination, stress and well-being support during the COVID-19 pandemic

Aim: To evaluate the impact of the pandemic on the well-being of cancer staff and determine the uptake of opt-in mitigation strategies. Materials & methods: Staff at Guy's Cancer Centre (London, UK) participated in an anonymized survey between May and August 2021. Results: Of 1182 staff, 257 (21.7%) participated. Ethnicity (p = 0.020) and comorbidity burden (p = 0.022) were associated with SARS-CoV-2 infection status. Of 199 respondents, seven (3.6%) were vaccine-hesitant, which was associated with low flu vaccine uptake (p < 0.001). Greater stress was associated with younger age (p = 0.030) and redeployment (p = 0.012). Lack of time and skepticism were barriers to using mental well-being resources. Conclusion: Albeit cautious, numerous trends the authors observed echo those in the published literature. Improved accessibility, awareness and utility of mental well-being resources are required.

Risk of COVID-19 death in cancer patients: an analysis from Guy's Cancer Centre and King's College Hospital in London

BACKGROUND

Using an updated dataset with more patients and extended follow-up, we further established cancer patient characteristics associated with COVID-19 death.

METHODS

Data on all cancer patients with a positive reverse transcription-polymerase chain reaction swab for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) at Guy's Cancer Centre and King's College Hospital between 29 February and 31 July 2020 was used. Cox proportional hazards regression was performed to identify which factors were associated with COVID-19 mortality.

RESULTS

Three hundred and six SARS-CoV-2-positive cancer patients were included. Seventy-one had mild/moderate and 29% had severe COVID-19. Seventy-two patients died of COVID-19 (24%), of whom 35 died <7 days. Male sex [hazard ratio (HR): 1.97 (95% confidence interval (CI): 1.15-3.38)], Asian ethnicity [3.42 (1. 59-7.35)], haematological cancer [2.03 (1.16-3.56)] and a cancer diagnosis for >2-5 years [2.81 (1.41-5.59)] or ≥5 years were associated with an increased mortality. Age >60 years and raised C-reactive protein (CRP) were also associated with COVID-19 death. Haematological cancer, a longer-established cancer diagnosis, dyspnoea at diagnosis and raised CRP were indicative of early COVID-19-related death in cancer patients (<7 days from diagnosis).

CONCLUSIONS

Findings further substantiate evidence for increased risk of COVID-19 mortality for male and Asian cancer patients, and those with haematological malignancies or a cancer diagnosis >2 years. These factors should be accounted for when making clinical decisions for cancer patients.

COVID-19 Risk Factors for Cancer Patients: A First Report with Comparator Data from COVID-19 Negative Cancer Patients

Very few studies investigating COVID-19 in cancer patients have included cancer patients as controls. We aimed to identify factors associated with the risk of testing positive for SARS CoV2 infection in a cohort of cancer patients. We analyzed data from all cancer patients swabbed for COVID-19 between 1st March and 31st July 2020 at Guy's Cancer Centre. We conducted logistic regression analyses to identify which factors were associated with a positive COVID-19 test. Results: Of the 2152 patients tested for COVID-19, 190 (9%) tested positive. Male sex, black ethnicity, and hematological cancer type were positively associated with risk of COVID-19 (OR = 1.85, 95%CI:1.37-2.51; OR = 1.93, 95%CI:1.31-2.84; OR = 2.29, 95%CI:1.45-3.62, respectively) as compared to females, white ethnicity, or solid cancer type, respectively. Male, Asian ethnicity, and hematological cancer type were associated with an increased risk of severe COVID-19 (OR = 3.12, 95%CI:1.58-6.14; OR = 2.97, 95%CI:1.00-8.93; OR = 2.43, 95%CI:1.00-5.90, respectively). This study is one of the first to compare the risk of COVID-19 incidence and severity in cancer patients when including cancer patients as controls. Results from this study have echoed those of previous reports, that patients who are male, of black or Asian ethnicity, or with a hematological malignancy are at an increased risk of COVID-19.

Update from the ReIMAGINE Prostate Cancer Screening Study NCT04063566: Inviting Men for Prostate Cancer Screening Using Magnetic Resonance Imaging

ReIMAGINE Screening is a single-centre study assessing the feasibility of biparametric magnetic resonance imaging as a screening tool for prostate cancer. The study outcomes will take us a step towards more accurate and less harmful prostate cancer screening.

The success of the Rapid Diagnostic Clinic (RDC) detecting new cancers in patients with non-localizing symptoms

303

Background: Rapid Diagnostic Clinics (RDC) are being set up across the UK allow primary care physicians to refer patients with symptoms concerning for cancer that do not fulfil tumour-specific two week wait urgent referral criteria. Guy’s RDC was established to address the high cancer related mortality in our network. There is little data assessing the effectiveness of RDC models is available in a British population. Methods: We evaluated all patients referred to Guy’s RDC pilot scheme between December 2016-June 2019 (n=1,341) to assess the rate and type of cancer diagnosed and clinical outcomes. Results: Of 1341 patients, 96 cancers were diagnoses (7.2%). Most common were lung (16%), haematological (13%) and colorectal (12%). A third were at early stage (I-II) and 40% received radical treatment. Median time to cancer diagnosis 28 days (IQR 15-47) and treatment 56 days (IQR 32-84). 75% of patients were suitable for anti-cancer treatment: surgery (26%), systemic (24%) and radiotherapy (14%). We plan to present updated data on > 2000 patients referred until June 2020. Overall 6% of patients were diagnosed with pre-malignant conditions. Conclusions: RDCs provide a streamlined pathway for complex vague symptoms patients which are challenging for primary care. The 7% rate of cancer diagnosis exceeds many tumour specific urgent pathways which supports the need for rapid tailored diagnostics. The detection of pre-malignant conditions in 6% allows surveillance and intervention to potentially improve long-term outcomes. RDCs are likely to be pivotal in the cancer recovery phase of the COVID-19 pandemic.

Disparities in COVID-19 severity and risk of death in cancer patients: Experiences from a U.K. cancer center

285

Background: There has been widespread evidence emerging regarding disparities between COVID-19 outcomes in patients of varying ethnicities and background. It is, however, unclear how various patient characteristics affect COVID-19 severity and risk of death in a cancer population. Methods: Our Cancer Centre was at the epicentre of the COVID-19 outbreak in the UK. A total of 156 cancer patients had a confirmed COVID-19 diagnosis between the 29th of February through the 12th of May 2020. Logistic/Cox proportional hazards models were used to identify which demographic and/or clinical characteristics were associated with COVID-19 severity/death. The regression models were defined through a directed acyclic graph (DAG) to decide upon the minimal adjustments required for each statistical model. Results: Of the 156 COVID-19 positive cancer patients, the most frequently reported tumour types were urological/gynaecological (29%), followed by haematological (18%) and breast (15%). 128 (82%) presented with mild/moderate COVID-19 and 28 (18%) with severe disease. Initial diagnosis of cancer >24m before COVID-19 (OR:1.74 (95%CI: 0.71-4.26)), presenting with fever (6.21 (1.76-21.99)), dyspnoea (2.60 (1.00-6.76)), gastro-intestinal symptoms (7.38 (2.71-20.16)), or higher levels of CRP (9.43 (0.73-121.12)) were linked with greater COVID-19 severity. During median follow-up of 37 days, 34 patients had died of COVID-19 (22%). Asian ethnicity (3.73 (1.28-10.91), palliative treatment (5.74 (1.15-28.79), initial diagnosis of cancer >24m before (2.14 (1.04-4.44), dyspnoea (4.94 (1.99-12.25), and increased CRP levels (10.35 (1.05-52.21)) were positively associated with COVID-19 death. Socioeconomic status (SES) was not found to be associated with either COVID-19 severity or risk of death. We will present updated data with more mature follow-up. Conclusions: In cancer patients, Asian ethnicity was found to be positively associated with COVID-19 death compared to Caucasian patients. However, SES was not associated with COVID-19 severity or risk of death thereby implying this was not due to poor access to healthcare. Future studies hence need to identify the underlying biological and/or societal reasons explaining these ethnic disparities in COVID-19 outcomes for cancer patients.

Cohort profile: King's Health Partners bladder cancer biobank

BACKGROUND

Bladder cancer (BC) is the 9th most common cancer worldwide, but little progress has been made in improving patient outcomes over the last 25 years. The King's Health Partners (KHP) BC biobank was established to study unanswered, clinically relevant BC research questions. Donors are recruited from the Urology or Oncology departments of Guy's Hospital (UK) and can be approached for consent at any point during their treatment pathway. At present, patients with bladder cancer are approached to provide their consent to provide blood, urine and bladder tissue. They also give access to medical records and linkage of relevant clinical and pathological data across the course of their disease. Between June 2017 and June 2019, 531 out of 997 BC patients (53.3%) gave consent to donate samples and data to the Biobank. During this period, the Biobank collected fresh frozen tumour samples from 90/178 surgical procedures (of which 73 were biopsies) and had access to fixed, paraffin embedded samples from all patients who gave consent. Blood and urine samples have been collected from 38 patients, all of which were processed into component derivatives within 1 to 2 h of collection. This equates to 193 peripheral blood mononuclear cell vials; 238 plasma vials, 224 serum vials, 414 urine supernatant vials and 104 urine cell pellets. This biobank population is demographically and clinically representative of the KHP catchment area.

CONCLUSION

The King's Health Partners BC Biobank has assembled a rich data and tissue repository which is clinically and demographically representative of the local South East London BC population, making it a valuable resource for future BC research.

Frequency of Pathogenic Germline Variants in CDH1, BRCA2, CHEK2, PALB2, BRCA1, and TP53 in Sporadic Lobular Breast Cancer

BACKGROUND

Invasive lobular breast cancer (ILC) accounts for approximately 15% of invasive breast carcinomas and is commonly associated with lobular carcinoma in situ (LCIS). Both have been shown to have higher familial risks than the more common ductal cancers. However, there are little data on the prevalence of the known high and moderate penetrance breast cancer predisposition genes in ILC. The aim of this study was to assess the frequency of germline variants in CDH1, BRCA2, BRCA1, CHEK2, PALB2, and TP53 in sporadic ILC and LCIS diagnosed in women ages ≤60 years.

METHODS

Access Array technology (Fluidigm) was used to amplify all exons of CDH1, BRCA2, BRCA1, TP53, CHEK2, and PALB2 using a custom-made targeted sequencing panel in 1,434 cases of ILC and 368 cases of pure LCIS together with 1,611 controls.

RESULTS

Case-control analysis revealed an excess of pathogenic variants in BRCA2, CHEK2, PALB2, and CDH1 in women with ILC. CHEK2 was the only gene that showed an association with pure LCIS [OR = 9.90; 95% confidence interval (CI), 3.42-28.66, P = 1.4 × 10^-5] with a larger effect size seen in LCIS compared with ILC (OR = 4.31; 95% CI, 1.61-11.58, P = 1.7 × 10^-3).

CONCLUSIONS

Eleven percent of patients with ILC ages ≤40 years carried germline variants in known breast cancer susceptibility genes.

IMPACT

Women with ILC ages ≤40 years should be offered genetic screening using a panel of genes that includes BRCA2, CHEK2, PALB2, and CDH1.

The acetaminophen metabolite N-acetyl-p-benzoquinone imine (NAPQI) inhibits glutathione synthetase in vitro; a clue to the mechanism of 5-oxoprolinuric acidosis?

1. Metabolic acidosis due to accumulation of l-5-oxoproline is a rare, poorly understood, disorder associated with acetaminophen treatment in malnourished patients with chronic morbidity. l-5-Oxoprolinuria signals abnormal functioning of the γ-glutamyl cycle, which recycles and synthesises glutathione. Inhibition of glutathione synthetase (GS) by N-acetyl-p-benzoquinone imine (NAPQI) could contribute to 5-oxoprolinuric acidosis in such patients. We investigated the interaction of NAPQI with GS in vitro. 2. Peptide mapping of co-incubated NAPQI and GS using mass spectrometry demonstrated binding of NAPQI with cysteine-422 of GS, which is known to be essential for GS activity. Computational docking shows that NAPQI is properly positioned for covalent bonding with cysteine-422 via Michael addition and hence supports adduct formation. 3. Co-incubation of 0.77 μM of GS with NAPQI (25-400 μM) decreased enzyme activity by 16-89%. Inhibition correlated strongly with the concentration of NAPQI and was irreversible. 4. NAPQI binds covalently to GS causing irreversible enzyme inhibition in vitro. This is an important novel biochemical observation. It is the first indication that NAPQI may inhibit glutathione synthesis, which is pivotal in NAPQI detoxification. Further studies are required to investigate its biological significance and its role in 5-oxoprolinuric acidosis.

Ischemic heart disease is associated with lower cortical volumetric bone mineral density of distal radius

In this study, high-resolution peripheral quantitative computed tomography (HR-pQCT) was used to investigate geometric, volumetric and microstructural parameters at the distal radius and at the distal tibia in participants with ischaemic heart disease. We found that, compared with participants without ischaemic heart disease, they had substantially lower cortical volumetric bone mineral density (BMD) at the distal radius.

INTRODUCTION

HR-pQCT captures novel aspects of bone geometry and volumetric bone mineral density (vBMD) and offers the ability to measure bone microarchitecture, but data relating measures obtained from this technique in patients with ischemic heart disease (IHD) are lacking.

METHODS

Here, we report an analysis from the Hertfordshire Cohort Study, where we were able to study associations between measures obtained from HR-pQCT of distal radius and distal tibia in 350 participants (184 men and 166 women) aged 71.5-80.5 years with or without IHD (e.g. heart attack, angina or heart failure; n = 75 and n = 275, respectively).

RESULTS

Analyses for all participants (men and women together) revealed that cortical vBMD (Ct.vBMD) was lower (p < 0.001) and cortical thickness (Ct.th) was not different (p = 0.519), whereas cortical porosity (Ct.Po) was higher (p = 0.016) in participants with IHD at the distal radius. Moreover, trabecular microarchitectural parameters were not significantly different in patients with IHD (p > 0.05 for all). Adjustment for a priori confounders (age, gender, body mass index, smoking status, alcohol consumption, high blood pressure and diabetes mellitus) did not materially affect the relationship described for Ct.vBMD (p = 0.002), but differences in Ct.Po were attenuated. Analyses in men alone revealed that only Ct.vBMD was lower at the distal radius in participants with IHD with and without adjustment for a priori confounders (p = 0.0002 and p = 0.004, respectively), whereas no statistical differences were found in women, although patterns of differences were similar in both sexes. Moreover, no association was found between IHD and bone parameters at the distal tibia either in men or women.

CONCLUSIONS

We have demonstrated that IHD is associated with lower Ct.vBMD of the distal radius.

1994 entry-level athletic training salaries

In this study, I examined salaries for entry-level positions in athletic training during the year 1994. An entry-level position was defined as a position to be filled with an athletic trainer certified by the NATA, with no full-time paid employment experience. According to the "Placement Vacancy Notice" (NATA, Dallas, TX) and "BYLINE" (Athletic Trainer Services, Inc, Mt Pleasant, MI), there were 432 entry-level vacancies in hospital/clinics, college/universities, and high school settings. A total of 271 surveys (63%) were returned. Overall, beginning salaries for entry-level athletic training positions were $23,228 (+/-$3,177) for a bachelor's degree and $25,362 (+/-$3,883) for a master's degree. A stipend ($4,216 +/- $2,039) was included in 86% of the high school positions. The term of contract for high school was usually a 10-month position (10.0 +/- .9 months), hospital/clinic, 12-months (11.7 +/- .7 months), while the college/university varied from 9 to 12 months (10.5 +/- 1.2 months). Also included in the study was fringe benefit information: pension (other than Social Security), life, medical, dental, and vision insurance. Continued studies are recommended to establish salary norms and trends for entry-level positions so that athletic trainers will understand what monetary compensation to expect for their services.

1992 entry-level athletic trainer salaries

The purpose of this study was to examine the salaries for entry-level positions in athletic training during the year 1992. An entry-level position was defined as an athletic trainer, certified by the National Athletic Trainers' Association (NATA), with no full-time paid employment experience. According to the "Placement Vacancy Notice" published by the NATA, there were 234 entry-level vacancies in the hospital/clinic, 135 with the college/university, and 58 at the high school setting. A survey was designed and mailed to the location of each of these 427 entry-level positions. Distribution of responses was 78 (33%), 55 (41%), and 23 (40%) for hospital/clinic, college/university, and high school, respectively. Overall, beginning salaries for entry-level athletic training positions were $23,108 (+/- $3,309) for a bachelor's degree and $25,223 (+/- $3, 794) for a master's degree. A stipend ($4,219 +/- $1,458) was included in most of the high school positions. Term of contract for high school was usually 10 months (10.2 +/- 0.8 months), hospital/clinic was 12 months (11.9 +/- 0.6 months), while the college/university varied from 9 to 12 months (10.8 +/- 1.3 months). Further studies are recommended to establish salary norms and trends for entry-level positions so that athletic trainers will understand what monetary compensation is expected for their services.

Comparison of three methods of assessing muscle strength and imbalance ratios of the knee

Three strength measurement methods for determining muscle strength and imbalance ratios of the knee were compared in 41 (23 female, 18 male) NCAA Division I track and field athletes. Peak quadriceps extensions and hamstring flexions were measured isotonically, isometrically, and isokinetically. Isokinetic measurements were performed on a Cybex II at 60 degrees /s. Isometric extension and flexion measurements were performed using the Nicholas Manual Muscle Tester (Lafayette Instruments; Lafayette, Ind). Isotonic measurements were done on both Universal and Nautilus apparatuses. Testing order was randomized to avoid a treatment order effect. A repeated measures ANOVA and a post hoc Tukey test were used to compare the three methods of assessing strength and imbalance ratios of the knee. Absolute strength values were significantly different according to gender and mode of testing. Bilateral strength imbalance ratios for knee flexion were significantly lower for the Nautilus leg curl machine. Ipsilateral strength imbalance ratios were significantly greater for the Cybex II. Our results indicated that absolute strength values cannot be interchanged between testing modes. Except for Cybex II (ipsilateral) and Nautilus (bilateral knee flexion), strength imbalance ratios could be interchanged.

Comparison of the histochemical and contractile properties of human triceps surae

The purpose of the study was to compare the contractile properties determined from an electrically stimulated twitch with histochemically determined fibre type parameters of the human triceps surae. Muscle samples were obtained from the medial head of the gastrocnemius of ten male athletes. Ages ranged from 20 to 29 years. Muscle samples from the belly of the medial gastrocnemius muscle were obtained using the needle biopsy technique. The samples were treated histochemically for myosin ATPase to classify the fibres as either slow twitch (ST) or fast twitch (FT) and to determine fibre areas. Surface electrical stimulation was used to determine muscle twitch parameters. The contractile variables of the muscle twitch were latency (L), time to peak force (TPF), peak force (PF), half-contraction time (1/2 CT) and half-relaxation time (1/2 RT). Backward elimination procedures for dependent variables were used to determine which contractile properties best represented the histochemical profile of the muscles. Prediction formulas were developed for FT and ST percentages (R2 = 0.98, p < 0.001), relative area percentage (R2 = 0.87, p < 0.001), and ST area (R2 = 0.85, p < 0.01). It was concluded that the use of the electrotensiometer (ETM) protocol was a valid testing procedure when studying physiological relationships of histochemical properties in intact human skeletal muscle.
