Background Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction. Methods This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index <20), moderate lockdowns (20–60), and full lockdowns (>60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models were used to explore the associations between lockdowns and non-operation. Intervals from diagnosis to surgery were compared across COVID-19 government response index groups. This study was registered at ClinicalTrials.gov , NCT04384926 . Findings Of eligible patients awaiting surgery, 2003 (10·0%) of 20 006 did not receive surgery after a median follow-up of 23 weeks (IQR 16–30), all of whom had a COVID-19-related reason given for non-operation. Light restrictions were associated with a 0·6% non-operation rate (26 of 4521), moderate lockdowns with a 5·5% rate (201 of 3646; adjusted hazard ratio [HR] 0·81, 95% CI 0·77–0·84; p<0·0001), and full lockdowns with a 15·0% rate (1775 of 11 827; HR 0·51, 0·50–0·53; p<0·0001). In sensitivity analyses, including adjustment for SARS-CoV-2 case notification rates, moderate lockdowns (HR 0·84, 95% CI 0·80–0·88; p<0·001), and full lockdowns (0·57, 0·54–0·60; p<0·001), remained independently associated with non-operation. Surgery beyond 12 weeks from diagnosis in patients without neoadjuvant therapy increased during lockdowns (374 [9·1%] of 4521 in light restrictions, 317 [10·4%] of 3646 in moderate lockdowns, 2001 [23·8%] of 11 827 in full lockdowns), although there were no differences in resectability rates observed with longer delays. Interpretation Cancer surgery systems worldwide were fragile to lockdowns, with one in seven patients who were in regions with full lockdowns not undergoing planned surgery and experiencing longer preoperative delays. Although short-term oncological outcomes were not compromised in those selected for surgery, delays and non-operations might lead to long-term reductions in survival. During current and future periods of societal restriction, the resilience of elective surgery systems requires strengthening, which might include...
Cerebrotendinous xanthomatosis is an autosomal recessive inborn error of metabolism that is an often missed but treatable cause of hereditary ataxia. We report a case of cerebrotendinous xanthomatosis (CTX) that was diagnosed only after the development of cognitive decline and adult onset ataxia in a 35-year-old man. He had poor scholastic performance in childhood followed by gradually progressive cognitive decline. He presented to us with severe cerebellar ataxia and oculomotor apraxia. The key features that led to the diagnosis of CTX were the history of cataracts in childhood and Achilles tendon xanthoma. His brain magnetic resonance imaging showed characteristic features of CTX, and the diagnosis was confirmed by demonstrating the mutation in exon 2 of the CYP27A1 gene. The recognition of CTX earlier could have prevented his significant disabilities. The definitive treatment is oral chenodeoxycholic acid, which will prevent the accumulation of the cholestanol, which is thought to be responsible for the neurotoxicity.
Aims To investigate the incidence of post colonoscopy colorectal cancer (PCCRC) at a district NHS trust and assess compliance with UK key performance indicators and quality assurance standards for colonoscopy guidelines endorsed by JAG and the ACPGBI Methods We conducted a retrospective review of our trust colorectal MDT database to identify patients diagnosed with colorectal cancer in the period between January 2016 till June 2019 who underwent a colonoscopy within 6-36 month prior to their diagnosis with colorectal cancer. Patient demographics, indication of colonoscopy, date of cancer diagnosis, procedure related factors such as quality of bowel preparation, presence of diverticular disease, prior history of inflammatory bowel disease, previously diagnosed polyps and also grade of endoscopist were extrapolated. Results 1323 patients were diagnosed with colorectal cancer during the study period, out of these there were 111 patients who underwent a colonoscopy within 6-36 month prior to their diagnostic colonoscopy. After exclusion of cases with anastomotic recurrence (n = 2) and cases with no PCCRC (n = 82), there were 27 patients with confirmed PCCRC in accordance with WEO classification (PCCRC 2.8%, acceptable target 5%) Upon review of the 27 cases with PCCRC, there was equal gender distribution while the majority were 71-80 years old. There was evidence of diverticular disease in 44% and previous colonic polyps in 48%. The quality of bowel preparation was recorded as good in 25 cases while grade of endoscopist was consultant (n = 24), associate specialist (n = 1), nurse endoscopist (n = 2) Conclusions The incidence of PCCRC in our trust falls within national guidelines.
