Manzella A, Ecker BL, Eskander MF, Grandhi MS, In H, Kravchenko T, Langan RC, Kennedy T, Alexander HR, Beninato T, Pitt HA. Operative trends for pancreatic and hepatic malignancies during the COVID-19 pandemic. Surgery 2024; 176:364-370. [PMID: 38582733 DOI: 10.1016/j.surg.2024.02.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 02/25/2024] [Indexed: 04/08/2024]
Abstract
BACKGROUND The COVID-19 pandemic disrupted routine health care, including many elective and non-cancer operations in the United States. Most hepato-pancreato-biliary malignancy patients require outpatient imaging, tissue sampling, and staging, and many undergo neoadjuvant therapy before operative intervention. The aims of this study were to evaluate the effect of the COVID-19 pandemic on hepato-pancreato-biliary oncologic operations and to determine whether trends in neoadjuvant therapy were altered by the pandemic. METHODS Adult patients in the United States undergoing oncologic operations for pancreatic, primary and secondary hepatic malignancies, with or without neoadjuvant therapy, were extracted from the Vizient Clinical Data Base. Control chart analysis was used to plot trends over time and to determine whether changes were statistically significant. Wilcoxon rank-sum tests also compared monthly operative volume from pre-pandemic (12 month) and pandemic (28 months) periods. RESULTS A total of 36,553 patients were identified over 40 months. Mean monthly pancreatic oncologic operations were unaffected by the pandemic (P = .257). Operations for pancreatic oncologic operations with prior neoadjuvant therapy increased throughout the pandemic (P = .002). Oncologic operations for primary and secondary hepatic malignancies were significantly reduced for 4 and 2 months, respectively, at the beginning of the pandemic but returned to their pre-pandemic baseline within 4 months (P = .169 and P = .598). CONCLUSION Pancreatic operation volumes for cancer did not change, but pancreatic operations after neoadjuvant therapy continued to increase during the pandemic. Operations for hepatic malignancy were transiently disrupted but quickly normalized. These observations suggest that surgery for hepato-pancreato-biliary malignancies was prioritized during the pandemic.

Abstract
BACKGROUND Impaired fasting glucose (IFG) is associated with the risk of various cancers, but the cumulative effect of IFG on gastrointestinal cancer risk remains unclear. This study evaluated the association between the cumulative exposure to IFG and gastrointestinal cancer risk. METHODS The authors extracted data from the Korean National Health Insurance Service and health examination data sets. Among individuals ≥40 years old who were free of diabetes or cancer, 1,430,054 who underwent national health examinations over 4 consecutive years from 2009 to 2012 were selected and followed up until gastrointestinal cancer diagnosis, death, or December 31, 2019. The IFG exposure score (range, 0-4) was based on the number of IFG diagnoses over 4 years. RESULTS The median follow-up duration was 6.4 years. Consistent normoglycemia for 4 years was found in 44.3% of the population, whereas 5.0% had persistent IFG and 50.7% had intermittent IFG. Compared to the group with an IFG exposure score of 0, groups with IFG exposure scores of 1, 2, 3, and 4 had a 5%, 8%, 9%, and 12% increased risk of gastrointestinal cancer, respectively (score 1: adjusted hazard ratio [aHR], 1.05; 95% confidence interval [CI], 1.01-1.08; score 2: aHR, 1.08; 95% CI, 1.04-1.12; score 3: aHR, 1.09; 95% CI, 1.05-1.14; score 4: aHR, 1.12; 95% CI, 1.06-1.19). Persistent IFG exposure was also associated with higher risks of individual cancer types (colorectum, stomach, pancreas, biliary tract, and esophagus). CONCLUSIONS Cumulative exposure to IFG is associated with an increased risk of developing gastrointestinal cancer, in a dose-dependent manner. PLAIN LANGUAGE SUMMARY Hyperglycemia, including both diabetes and prediabetes, has been associated with an increased risk of various cancers. However, the cumulative effect of impaired fasting glucose on the risk of developing gastrointestinal cancer remains unclear. A frequent diagnosis of impaired fasting glucose was dose-dependently associated with a higher risk of developing overall gastrointestinal cancer. Furthermore, risks of individual cancer types increased with persistent impaired fasting glucose. Early detection of hyperglycemia and strict glycemic control can lower the risk of gastrointestinal cancer by reducing hyperglycemic burden. Additionally, for some individuals, lifestyle changes such as managing metabolic syndrome or abstaining from alcohol may also be helpful.

[PMID: 38375089 PMCID: PMC10875236 DOI: 10.1016/j.pmedr.2024.102649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 02/06/2024] [Accepted: 02/07/2024] [Indexed: 02/21/2024] Open
Abstract
Objectives The impact of the coronavirus disease (COVID-19) pandemic on cancer screening has become a global concern; compared with pre-pandemic levels, the number of individuals who underwent population-based cancer screening in Japan decreased by 10-30% in fiscal year (FY)2020. Therefore, it is important to monitor subsequent changes in the number of participants. Methods This descriptive study analysed data from a national database to determine changes from 2017 to 2021 in the number of people screened for gastric cancer (upper gastrointestinal [UGI] series or endoscopy), colorectal cancer (faecal immunochemical test), lung cancer (chest X-ray), breast cancer (mammography), and cervical cancer (Pap smear). Results Compared with the pre-pandemic period (FY 2017-2019), the number of participants in screening programmes in FY2021 decreased maximally for the gastric cancer UGI series (2.8 million to 2.2 million; -23.3 %), followed by those for lung cancer (7.9 million to 7.3 million; -8.2 %), colorectal cancer (8.4 million to 7.8 million; -7.3 %), breast cancer (3.1 million to 3.0 million; -4.5 %), and cervical cancer (4.3 million to 4.1 million; -3.2 %). Conversely, the number of people screened for endoscopic gastric cancer screening increased (1.0 million to 1.2 million; +13.1 %). Conclusions The number of participants, which decreased sharply immediately after the onset of the COVID-19 pandemic, recovered only slightly in FY2021 and did not return to pre-pandemic levels yet, except for endoscopic gastric cancer screening. Therefore, the impact of this decline in participation in cancer-detection programmes and changes in mortality should be monitored carefully.

[PMID: 38275566 PMCID: PMC10813896 DOI: 10.3390/diseases12010004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 12/12/2023] [Accepted: 12/21/2023] [Indexed: 01/27/2024] Open
Abstract
The impact of the COVID-19 pandemic was very broad and substantial, affecting a variety of fields worldwide. In Japan, the infection began spreading in March 2020. At that time, the government alerted people to cancel overseas travel, and encouraged wearing of masks, handwashing, sanitizing and keeping social distance. We sought to determine how COVID-19 infections affected other infectious diseases by investigating the trends in seven gastrointestinal infections that are listed among the 77 important infectious diseases designated by the National Institute of Infectious Diseases. We compared seven gastrointestinal infectious diseases, namely cholera, bacterial dysentery, enterohemorrhagic Escherichia coli, typhoid fever, paratyphoid fever, amoebic dysentery, and giardiasis, in terms of numbers of new cases before the COVID-19 pandemic (2012-2019) and during the pandemic (2020-2022). During the COVID-19 pandemic period (2020-2022), the incidence of the seven infections decreased significantly (p < 0.05) compared with before the pandemic (2012-2019). The sharp and significant decline in incidence of these seven infections in Japan during the COVID-19 pandemic period (2020-2022) appears to be due to restrictions on overseas travel and strict anti-infection measures, such as self-quarantine and encouragement of handwashing and sanitizing. The number of new cases of gastrointestinal infections in Japan is expected to increase in 2024 as these measures lapse. It is important for physicians to continue to monitor trends in gastrointestinal infections and educate people about proper infection prevention.

Abstract
Background/Aims Non-time-sensitive gastrointestinal endoscopy was deferred because of the risk of exposure to coronavirus disease 2019 (COVID-19), but no population-based studies have quantified the adverse impact on gastrointestinal procedures. This study examined the impact of the COVID-19 pandemic on the performance of esophagogastroduodenoscopy (EGD), colonoscopy, ERCP, and abdominal ultrasonography (US) in South Korea. Methods This nationwide, population-based study compared the claim data of EGD, colonoscopy, ERCP, and abdominal US in 2020 and 2021 (COVID-19 era) with those in 2019 (before the COVID-19 era). Results During the first year (2020) of the COVID-19 pandemic, the annual claim data of EGD and colonoscopy were reduced by 6.3% and 6.9%, respectively, but those of ERCP and abdominal US were increased by 1.0% and 2.9%, compared to those in 2019. During the first surge (March and April 2020) of COVID-19, the monthly claim data of EGD, colonoscopy, ERCP, and abdominal US were reduced by 28.8%, 43.8%, 5.1%, and 21.6%, respectively, in March 2020, and also reduced by 17.2%, 32.8%, 4.4%, and 9.5%, respectively, in April 2020, compared to those in March and April 2019. During March and April 2020, the monthly claims of ERCP, compared with those in 2019, declined less significantly than those of EGD and colonoscopy (both p<0.001). Conclusions The claims of EGD and colonoscopy were reduced more significantly than those of ERCP and abdominal US during the COVID-19 pandemic because ERCPs are time-sensitive procedures and abdominal USs are non-aerosolized procedures.

Abstract
BACKGROUND COVID-19 disrupted elective operations, cancer screening, and routine medical care while simultaneously overwhelming hospital staff and supplies. Operations for gastrointestinal (GI) malignancies rely on endoscopic screening, staging, and neoadjuvant therapy (NAT), each of which was disrupted by the pandemic. The aim was to evaluate the effect of the COVID-19 pandemic on the US national rates of gastrointestinal oncologic operations. METHODS The Vizient Clinical Data Base® was queried for oncologic operations for esophageal, gastric, and colorectal malignancies with and without NAT from March 2019 to March 2022. Control chart analysis examined operative volume over time while Wilcoxon rank sum tests were used to compare mean monthly volume before and during the pandemic. RESULTS A total of 95,912 patients were identified over 36 months; 5.8% esophageal, 6.3% gastric, 77.5% colonic, and 10.4% rectal operations. Esophageal operative volume decreased for 9 months during the pandemic and was significantly lower during than before the pandemic (p=0.002). Gastric operations decreased for 10 months early in the pandemic, but rebounded so that after 2 years volumes were unchanged (p=0.49). Colonic operations experienced a sharp decrease for 4 months at the beginning of the pandemic, but volumes quickly increased and overall were unchanged (p=0.29). Rectal operations decreased for 13 months and were significantly lower during than before the pandemic (p=0.018). Oncologic operations for patients receiving NAT varied. CONCLUSION COVID-19 significantly disrupted the volume of gastrointestinal oncologic operations in the USA. Esophageal and rectal oncologic operations experienced prolonged and significant reductions while gastric and colonic oncologic operations transiently decreased but rebounded during the pandemic.

Abstract
Objectives This study aimed to evaluate the socioeconomic inequality in gastric cancer (GC) screening in Korea. Socioeconomic inequality was assessed using both organized and opportunistic screening according to income and educational level. Methods GC screening data were obtained from the 2009-2022 Korean National Cancer Screening Survey. The final analysis included 47,163 cancer-free men and women. The weighted cancer screening rate was estimated using joinpoint regression. The inequality indices were measured in terms of both the absolute slope index of inequality (SII) and the relative index of inequality (RII) using the Poisson regression model. Results The organized screening rate for GC increased from 38.2% in 2009 to 70.8% in 2022, whereas the opportunistic screening rate decreased from 18.8 to 4.5%. Regarding educational inequality, a negative SII value was observed [-3.5, 95% confidence interval (CI), -7.63-0.83%] in organized screening, while a positive SII (9.30%; 95% CI, 6.69-11.91%) and RII (1.98%; 95% CI, 1.59-2.46) were observed in opportunistic screening. Furthermore, income inequality was not found in organized GC screening; however, overall SII and RII for opportunistic screening were 7.72% (95% CI, 5.39-10.5) and 1.61 (95% CI, 1.42-1.81), respectively. Conclusion Organized screening rates have grown gradually over time and account for the majority of GC screenings in South Korea. While no socioeconomic inequalities were found in organized screening, significant socioeconomic inequalities were found in opportunistic screening.

Changes in the Number of Gastrointestinal Cancers and Stage at Diagnosis with COVID-19 Pandemic in Japan: A Multicenter Cohort Study. Cancers (Basel) 2023; 15:4410. [PMID: 37686686 PMCID: PMC10487252 DOI: 10.3390/cancers15174410] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 08/13/2023] [Accepted: 09/01/2023] [Indexed: 09/10/2023] Open
Abstract
This retrospective cohort study compared the number of newly diagnosed patients, stage at diagnosis, and detection process of gastrointestinal cancers based on hospital-based cancer registry data at two tertiary Japanese hospitals. The pre-COVID-19 period was from January 2017 to February 2020, with phase 1 (midst of COVID-19 pandemic) from March to December 2020 and phase 2 (the transition period to the "new normal") from January to December 2021. Each month, the number of patients diagnosed with esophageal, gastric, colorectal, pancreatic, liver, and biliary tract cancers were aggregated, classified by stage and detection process, and compared, including a total of 6453 patients. The number of colorectal Stage 0-II patients decreased significantly in phase 1 and increased in phase 2. The total number of colorectal cancer patients returned to pre-COVID-19 levels (mean monthly patients [SD]: 41.61 [6.81] vs. 36.00 [6.72] vs. 46.00 [11.32]). The number of patients with gastric cancer Stage I significantly decreased in phase 2 following phase 1. The number of gastric cancer patients decreased significantly from pre-COVID-19 levels (30.63 [6.62] vs. 22.40 [5.85] vs. 24.50 [4.15]). During phase 2, the number of patients diagnosed after screening with colorectal cancer increased significantly, whereas that with gastric cancer remained considerably lower. The number of Stage III colorectal and gastric cancer patients increased significantly from the pre-COVID-19 levels. Thus, gastric cancer may not be optimally screened during phases 1 and 2. There was a significant increase in patients with Stage III colorectal and gastric cancers from the pre-COVID-19 period; hence, the stage at diagnosis may have progressed.
