Savings in social expenditures for work incapacity in patients with inflammatory bowel disease depend on access to innovative therapies in Poland.

OBJECTIVES: Inflammatory bowel diseases (IBD) are an increasing burden for societies. We examined Polish Social Insurance Institution (ZUS) work incapacity expenditures for people with IBD compared with the general population. METHODS: Aggregate data were obtained on ZUS expenditures between 2012 and 2021 in Polish zlotys (PLN). Annual work incapacity benefit expenditures were analyzed and IBD benefit expenditures were examined relative to innovative IBD drug utilization in individual provinces. RESULTS: Between 2012 and 2021, annual ZUS expenditures per person increased, while expenditures per IBD patient decreased. Proportionally, absenteeism was the largest ZUS expenditure in the general population, while disability pensions were the largest in the IBD population. ZUS expenditures due to absenteeism in the general population increased by PLN 282 per person; those due to disability pensions decreased by PLN 85. Disability pension spending due to Crohn's disease (CD) and ulcerative colitis (UC) decreased by PLN 371 and PLN 284, respectively, while absenteeism spending per person with CD and UC decreased (PLN 58 and PLN 35, respectively). Nationwide in 2021, 8.5% of people with CD and 1.9% of those with UC received innovative drugs. The percentage of people receiving innovative drugs and ZUS expenditure per person were inversely related in 9/16 provinces for CD and 5/16 for UC. CONCLUSION: Polish state spending on work incapacity benefits increased in the general population but decreased in people with IBD between 2012 and 2021. Use of innovative drugs was associated with reduced spending per person with IBD in some provinces.

To push or to pull? A clinical audit on the efficacy and safety of the pull and push percutaneous endoscopic gastrostomy techniques in oncological patients.

BACKGROUND: The peroral "pull" technique and the direct "push" procedure are the two main methods for percutaneous endoscopic gastrostomy (PEG) placement. Although pull-PEG is generally recommended as the first-line modality, many oncological patients require a push-PEG approach to prevent tumor seeding or overcome tumor-related obstruction. OBJECTIVE: We aimed to compare the efficacy and safety of both PEG procedures in cancer patients. METHODS: We retrospectively analyzed all consecutive PEG procedures within a tertiary oncological center. Patients were followed up with the hospital databases and National Cancer Registry to assess the technical success rate for PEG placement, the rate of minor and major adverse events (AEs), and 30-day mortality rates. We compared those outcomes between the two PEG techniques. Finally, risk factors for PEG-related adverse events were analyzed using a multivariable Cox proportional-hazard regression model adjusted for patients' sex, age, performance status (ECOG), Body Mass Index (BMI), diabetes, chemoradiotherapy (CRT) status (pre-/current-/post-treatment), and type of PEG. RESULTS: We included 1055 PEG procedures (58.7% push-PEG/41.4% pull-PEG) performed in 994 patients between 2014 and 2021 (mean age 62.0 [±10.7] yrs.; 70.2% males; indication: head-and-neck cancer 75.9%/other cancer 24.1%). The overall technical success for PEG placement was 96.5%. Although the "push" technique had a higher rate of all AEs (21.4% vs. 7.1%, Hazard Ratio [HR]  = 2.9; 95% CI = 1.9-4.3, p < 0.001), most of these constituted minor AEs (71.9%), such as tube dislodgement. The methods had no significant difference regarding major AEs and 30-day mortality rates. Previous CRT was associated with an increased risk of major AEs (hazard ratio = 2.7, 95% CI = 1.0-7.2, p = 0.042). CONCLUSION: The risk of major AEs was comparable between the push- and pull-PEG techniques in cancer patients. Due to frequent tube dislodgement in push-PEG, the pull technique may be more suitable for long-term feeding. Previous CRT increases the risk of major AEs, favoring early ("prophylactic") PEG placement when such treatment is expected.

Diagnostic and therapeutic recommendations on Helicobacter pylori infection. Recommendations of the Working Group of the Polish Society of Gastroenterology.

Helicobacter pylori remains a major health problem worldwide, causing considerable morbidity and mortality due to peptic ulcer disease and gastric cancer. These guidelines constitute an update of the previous "Recommendations on the diagnosis and management of Helicobacter pylori infection" issued in 2014. They have been developed by a Task Force organized by the Governing Board of the Polish Society of Gastroenterology. They discuss, with particular emphasis on new scientific data covering papers published since 2014: the epidemiology, clinical presentation, diagnostic principles and criteria for the diagnosis, and recommendations for the treatment of H. pylori infection. The guidelines in particular determine which patients need to be tested and treated for infection. The Task Force also discussed recommended treatment algorithms. Accordingly, a combination of available evidence and consensus-based expert opinion were used to develop these best practice advice statements. It is worth noting that guidelines are not mandatory to implement but they offer advice for pragmatic, relevant and achievable diagnostic and treatment pathways based on established key treatment principles and using local knowledge and available resources to guide regional practice.

Diverticular Inflammation and Complication Assessment classification, CODA score and fecal calprotectin in clinical assessment of patients with diverticular disease: A decision curve analysis.

BACKGROUND AND AIMS: The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. METHODS: A three-year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. RESULTS: At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13-5.10) and showed moderate discrimination (c-statistic: 0.685; 0.614-0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow-up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. CONCLUSIONS: FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

Prevalence and Natural History of Segmental Colitis Associated With Diverticulosis.

INTRODUCTION: We assessed the prevalence and clinical outcomes of segmental colitis associated with diverticulosis (SCAD) in patients with newly diagnosed diverticulosis. METHODS: A 3-year international, multicenter, prospective cohort study was conducted involving 2,215 patients. RESULTS: SCAD diagnosis was posed in 44 patients (30 male patients; median age: 64.5 years; prevalence of 1.99%, 95% confidence interval, 1.45%-2.66%). Patients with SCAD types D and B showed worse symptoms, higher fecal calprotectin values, needed more steroids, and reached less likely complete remission. DISCUSSION: Although SCAD generally had a benign outcome, types B and D were associated with more severe symptoms and worse clinical course.

This paper is an update of the diagnostic and therapeutic recommendations of the National Consultant for Gastroenterology and the Polish Society of Gastroenterology from 2013. It contains 49 recommendations for the diagnosis and treatment, both pharmacological and surgical, of ulcerative colitis in adults. The guidelines were developed by a group of experts appointed by the Polish Society of Gastroenterology and the National Consultant in the field of Gastroenterology. The methodology related to the GRADE methodology was used to assess the quality of available evidence and the strength of therapeutic recommendations. The degree of expert support for the proposed statements was assessed on a 6-point Likert scale. Voting results, together with comments, are included with each statement.

Narrow-band imaging vs Lugol chromoendoscopy in screening for esophageal squamous cell neoplasia: a randomized trial.

INTRODUCTION: To date, there is no established optimal method for endoscopic detection of esophageal squamous cell neoplasia in high­risk individuals. OBJECTIVES: We aimed to compare the performance of narrow­band imaging (NBI) and Lugol chromoendoscopy in screening for esophageal neoplasia among patients with a history of treatment for head and neck squamous cell cancer (HNSCC). PATIENTS AND METHODS: We randomly assigned 300 patients who had completed curative treatment for HNSCC at least 1 year prior to the inclusion to undergo either NBI or Lugol endoscopy (2:1 ratio). Following white­light examination of the esophagus, the assigned imaging study was performed, and biopsies were taken from any suspicious lesions identified using NBI or Lugol chromoendoscopy. The primary end point was positive predictive value (PPV) of the biopsied lesion for a diagnosis of esophageal neoplasia (high­grade intraepithelial neoplasia [HG­IEN] or invasive esophageal squamous cell carcinoma [ESCC]). The secondary end points included the number of biopsied lesions, duration of esophagus examination, and endoscopy tolerance. RESULTS: In 294 patients included in the final analysis (NBI, n = 204; Lugol chromoendoscopy, n = 90), we diagnosed 3 ESCCs (1.02%) and 2 HG­IENs (0.68%). The PPV of NBI and Lugol chromoendoscopy in per­lesion analysis was 7.69% (95% CI, 0.94%-25.1%) and 8.11% (95% CI, 1.7%-21.9%), respectively (P >0.99). NBI outperformed Lugol chromoendoscopy in terms of the rate of patients requiring biopsy (12.75% vs 41.11%; P = 0.003), duration of esophagus examination (3.5 min vs 5.15 min; P <0.001), and endoscopy tolerance assessed on the visual analog scale (25 mm vs 36.5 mm; P = 0.002). CONCLUSIONS: With a PPV comparable to that of Lugol chromoendoscopy, but a lower number of biopsies required, shorter examination time, and better patient tolerance, NBI could be considered the primary screening method for ESCC in patients with HNSCC.

A Global Perspective on Gastric Cancer Screening: Which Concepts Are Feasible, and When?

BACKGROUND: Gastric cancer (GC) remains the fifth most common cancer and the third most common cause of cancer-related death globally. In 2022, GC fell into the scope of the updated EU recommendations for targeted cancer screening. Given the growing awareness of the GC burden, we aimed to review the existing screening strategies for GC in high-risk regions and discuss potentially applicable modalities in countries with low-to-intermediate incidence. METHODS: The references for this Review article were identified through searches of PubMed with the search terms "gastric cancer", "stomach cancer", "Helicobacter pylori", and "screening" over the period from 1995 until August 2022. RESULTS: As Helicobacter pylori (H. pylori)-induced gastritis is the primary step in the development of GC, the focus on GC prevention may be directed toward testing for and treating this infection. Such a strategy may be appealing in countries with low- and intermediate- GC incidence. Other biomarker-based approaches to identify at-risk individuals in such regions are being evaluated. Within high-incidence areas, both primary endoscopic screening and population-based H. pylori "test-and-treat" strategies represent cost-effective models. CONCLUSIONS: Given the significant variations in GC incidence and healthcare resources around the globe, screening strategies for GC should be adjusted to the actual conditions in each region. While several proven tools exist for accurate GC diagnosis, a universal modality for the screening of GC populations remains elusive.

Comparison of Quality Measures for Detection of Neoplasia at Screening Colonoscopy.

BACKGROUND & AIMS: The proportion of colonoscopies with at least one adenoma (adenoma detection rate [ADR]) is inversely associated with colorectal cancer (CRC) risk and death. The aim of this study was to examine whether such associations exist for colonoscopy quality measures other than ADR. METHODS: We used data from the Polish Colorectal Cancer Screening Program collected in 2000-2011. For all endoscopists who performed ≥100 colonoscopies we calculated detection rates of adenomas (ADR), polyps (PDR), and advanced adenomas (≥10 mm/villous component/high-grade dysplasia [AADR]); and number of adenomas per colonoscopy (APC) and per colonoscopy with ≥1 adenoma (APPC). We followed patients until CRC diagnosed before recommended surveillance, death, or December 31, 2019. We estimated hazard ratios (HRs) and 95% confidence intervals (CIs) using Cox proportional-hazard models. We used Harrell's C statistic to compare the predictive power of the quality measures. RESULTS: Data on 173,287 patients (median age, 56 years; 37.8% male) and 262 endoscopists were used. During a median follow-up of 10 years and 1,490,683 person-years, we identified 395 CRCs. All quality measures were significantly associated with CRC risk and death. The relative reductions in CRC risk were as follows: for ADR ≥24.9% (reference <12.1%; HR, 0.41; 95% CI, 0.25-0.66), PDR ≥42.7% (reference <19.9%; HR, 0.35; 95% CI, 0.24-0.51), AADR ≥9.1% (reference <4.1%; HR, 0.69; 95% CI, 0.49-0.96), APC ≥0.37 (reference <0.15; HR, 0.35; 95% CI, 0.21-0.58), and APPC ≥1.54 (reference <1.19; HR, 0.54; 95% CI, 0.35-0.83). AADR was the only quality measure with significantly lower predictive power than ADR (Harrell's C, 59.7 vs 63.4; P = .001). Similar relative reductions were observed for CRC death. CONCLUSIONS: This large observational study confirmed the inverse association between ADR and CRC risk and death. The PDR and APC quality measures appear to be comparable with ADR.

Effect of Colonoscopy Screening on Risks of Colorectal Cancer and Related Death.

BACKGROUND: Although colonoscopy is widely used as a screening test to detect colorectal cancer, its effect on the risks of colorectal cancer and related death is unclear. METHODS: We performed a pragmatic, randomized trial involving presumptively healthy men and women 55 to 64 years of age drawn from population registries in Poland, Norway, Sweden, and the Netherlands between 2009 and 2014. The participants were randomly assigned in a 1:2 ratio either to receive an invitation to undergo a single screening colonoscopy (the invited group) or to receive no invitation or screening (the usual-care group). The primary end points were the risks of colorectal cancer and related death, and the secondary end point was death from any cause. RESULTS: Follow-up data were available for 84,585 participants in Poland, Norway, and Sweden - 28,220 in the invited group, 11,843 of whom (42.0%) underwent screening, and 56,365 in the usual-care group. A total of 15 participants had major bleeding after polyp removal. No perforations or screening-related deaths occurred within 30 days after colonoscopy. During a median follow-up of 10 years, 259 cases of colorectal cancer were diagnosed in the invited group as compared with 622 cases in the usual-care group. In intention-to-screen analyses, the risk of colorectal cancer at 10 years was 0.98% in the invited group and 1.20% in the usual-care group, a risk reduction of 18% (risk ratio, 0.82; 95% confidence interval [CI], 0.70 to 0.93). The risk of death from colorectal cancer was 0.28% in the invited group and 0.31% in the usual-care group (risk ratio, 0.90; 95% CI, 0.64 to 1.16). The number needed to invite to undergo screening to prevent one case of colorectal cancer was 455 (95% CI, 270 to 1429). The risk of death from any cause was 11.03% in the invited group and 11.04% in the usual-care group (risk ratio, 0.99; 95% CI, 0.96 to 1.04). CONCLUSIONS: In this randomized trial, the risk of colorectal cancer at 10 years was lower among participants who were invited to undergo screening colonoscopy than among those who were assigned to no screening.

Update of the diagnostic and therapeutic guidelines for gastro-entero-pancreatic neuroendocrine neoplasms (recommended by the Polish Network of Neuroendocrine Tumours) [Aktualizacja zalecen ogólnych dotyczacych postepowania diagnostyczno-terapeutycznego w nowotworach neuroendokrynnych ukladu pokarmowego (rekomendowane przez Polska Siec Guzów Neuroendokrynnych)].

Continuous progress in the diagnostics and treatment of neuroendocrine neoplasms (NENs), the emerging results of new clinical trials, and the new guidelines issued by medical societies have prompted experts from the Polish Network of Neuroendocrine Tumours to update the 2017 recommendations regarding the management of neuroendocrine neoplasms. This article presents the general recommendations for the management of NENs, resulting from the findings of the experts participating in the Fourth Round Table Conference, entitled "Polish Guidelines for the Diagnostics and Treatment of Neuroendocrine Neoplasms of the gastrointestinal tract, Zelechów, June 2021". Drawing from the extensive experience of centres treating these cancers, we hope that we have managed to formulate the optimal method of treating patients with NENs, applying the latest reports and achievements in the field of medicine, which can be effectively implemented in our country. The respective parts of this work present the approach to the management of: NENs of the stomach and duodenum (including gastrinoma), pancreas, small intestine, and appendix, as well as large intestine.

Pancreatic neuroendocrine neoplasms - update of the diagnostic and therapeutic guidelines (recommended by the Polish Network of Neuroendocrine Tumours) [Nowotwory neuroendokrynne trzustki - uaktualnione zasady diagnostyki i leczenia (rekomendowane przez Polska Siec Guzów Neuroendokrynych)].

In this paper, we present the current guidelines for the diagnostics and management of pancreatic neuroendocrine neoplasms (PanNENs) developed by Polish experts providing care for these patients in everyday clinical practice. In oncological diagnostics, in addition to biochemical tests, molecular identification with the use of NETest liquid biopsy and circulating microRNAs is gaining importance. Both anatomical and functional examinations (including new radiopharmaceuticals) are used in imaging diagnostics. Histopathological diagnosis along with immunohistochemical examination still constitute the basis for therapeutic decisions. Whenever possible, surgical procedure is the treatment of choice. Pharmacological management including biotherapy, radioisotope therapy, targeted molecular therapy and chemotherapy are important methods of systemic therapy. Treatment of PanNENs requires a multidisciplinary team of specialists in the field of neuroendocrine neoplasms.

Gastroduodenal neuroendocrine neoplasms including gastrinoma - update of the diagnostic and therapeutic guidelines (recommended by the Polish Network of Neuroendocrine Tumours) [Nowotwory neuroendokrynne zoladka i dwunastnicy z uwzglednieniem gastrinoma - uaktualnione zasady postepowania (rekomendowane przez Polska Siec Guzów Neuroendokrynnych)].

After another meeting of experts of the Polish Network of Neuroendocrine Tumours, updated recommendations for the management of patients with gastric and duodenal neuroendocrine neoplasms, including gastrinoma, have been issued. As before, the epidemiology, pathogenesis and clinical symptoms of these neoplasms have been discussed, as well as the principles of diagnostic procedures, including biochemical and histopathological diagnostics and tumour localisation, highlighting the changes introduced in the recommendations. Updated principles of therapeutic management have also been presented, including endoscopic and surgical treatment, and the options of pharmacological and radioisotope treatment. The importance of monitoring patients with gastric and duodenal NENs, including gastrinoma, has also been emphasised.

Colorectal neuroendocrine neoplasms - update of the diagnostic and therapeutic guidelines (recommended by the Polish Network of Neuroendocrine Tumours) [Nowotwory neuroendokrynne jelita grubego - uaktualnione zasady diagnostyki i leczenia (rekomendowane przez Polska Siec Guzów Neuroendokrynych)].

Colorectal neuroendocrine neoplasm (CRNEN), especially rectal tumours, are diagnosed with increased frequency due to the widespread use of colonoscopy, including screening examinations. It is important to constantly update and promote the principles of optimal diagnostics and treatment of these neoplasms. Based on the latest literature and arrangements made at the working meeting of the Polish Network of Neuroendocrine Tumours (June 2021), this paper includes updated and supplemented data and guidelines for the management of CRNEN originally published in Endokrynologia Polska 2017; 68: 250-260.

Neuroendocrine neoplasms of the small intestine and the appendix - update of the diagnostic and therapeutic guidelines (recommended by the Polish Network of Neuroendocrine Tumours) [Nowotwory neuroendokrynne jelita cienkiego i wyrostka robaczkowego - uaktualnione zasady diagnostyki i leczenia (rekomendowane przez Polska Siec Guzów Neuroendokrynnych)].

Updated Polish recommendations for the management of patients with neuroendocrine neoplasms (NENs) of the small intestine (SINENs) and of the appendix (ANENs) are presented here. The small intestine, and especially the ileum, is one of the most common locations for these neoplasms. Most of them are well-differentiated and slow-growing tumours; uncommonly - neuroendocrine carcinomas. Their symptoms may be untypical and their diagnosis may be delayed or accidental. Najczesciej pierwsza manifestacja ANEN jest jego ostre zapalenie. Typical symptoms of carcinoid syndrome occur in approximately 20-30% of SINENs patients with distant metastases. In laboratory diagnostics the assessment of 5-hydroxyindoleacetic acid concentration is helpful in the diagnosis of carcinoid syndrome. The most commonly used imaging methods are ultrasound examination, computed tomography, magnetic resonance imaging, colonoscopy and somatostatin receptor imaging. Histopathological examination is crucial for the proper diagnosis and treatment of patients with SINENs and ANENs. The treatment of choice is a surgical procedure, either radical or palliative. Long-acting somatostatin analogues (SSAs) are essential in the medical treatment of functional and non-functional SINENs. In patients with SINENs, at the stage dissemination with progression during SSAs treatment, with high expression of somatostatin receptors, radioisotope therapy should be considered first followed by targeted therapies - everolimus. After the exhaustion of the above available therapies, chemotherapy may be considered in selected cases. Recommendations for patient monitoring are also presented.

Biologic treatment of inflammatory bowel disease in Poland, 2012-2020: nationwide data.

INTRODUCTION: The frequency of biologic drug treatment for Polish patients diagnosed with ulcerative colitis (UC) or Crohn disease (CD) has been insufficiently studied. OBJECTIVES: We aimed to analyze the use of biologic treatments among Polish patients suffering from inflammatory bowel diseases (IBDs). PATIENTS AND METHODS: We used administrative data collected by the National Health Fund (Narodowy Fundusz Zdrowia [NFZ]), Poland's sole public health care payer. IBD cases were defined as cases with at least 2 records assigned code K50 or K51 according to the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD­10) and either at least 2 reimbursed prescriptions for IBD drugs or intestinal surgery preceding the record. We identified IBD patients receiving biologic treatments reimbursed by the NFZ in the years 2012-2020. We assessed the percentages of patients receiving biologic treatments in terms of disease type, sex, age group, and place of residence. RESULTS: While 6.8% of Polish CD patients received biologic treatment in 2012, that figure reached 7.9% by 2020. Biologic treatments were given to 0.4% of UC patients in 2014, and 1.6% in 2020. Among patients with both CD and UC, significantly fewer women received biologic therapy than men. The highest percentages of patients receiving biologic treatment for CD and UC were found in the 10-19 age group, while patients over 70 were the adults most rarely treated with biologic drugs. CONCLUSIONS: We showed a growing use of biologic agents in the treatment of IBD in Poland. Womenreceive biologic treatment for IBD significantly less frequently than men. The pediatric population features the highest proportion of patients receiving such treatment.

Nationwide data on epidemiology of inflammatory bowel disease in Poland between 2009 and 2020.

INTRODUCTION: The epidemiology of inflammatory bowel disease (IBD) in Poland has been recognized to only a limited extent. OBJECTIVES: We aimed to estimate the prevalence and incidence of IBD by analyzing data from the National Health Fund, Poland's sole public health insurer. PATIENTS AND METHODS: Administrative health claims collected over the 2009-2020 period were used to identify patients with Crohn's disease (CD) or ulcerative colitis (UC). A definition of a case comprised at least 2 records assigned K50 or K51 codes, plus at least 2 prescriptions for IBD drugs reimbursed, or else intestinal surgery preceding the record. The crude and European age­ standardized rates (EASR) and 95% CIs were calculated for prevalence and incidence. Time trends were also analyzed. RESULTS: As of 2020, there were 23 574 patients with CD and 73 235 with UC. The CD and UC prevalence was respectively 61.6 (EASR 60.3) and 191.4 (EASR 187.85) per 100 000. The prevalence of CD and UC was higher in men (64.1; EASR 61.3 and 201.4; EASR 202.7, respectively) than in women (59.3; EASR 58.4 and 182.0; EASR 175.5, respectively). The incidence of CD was 4.7 per 100 000 (EASR 4.6), and that of UC 12.5 (EASR 12.3). Through the period 2012-2018, the prevalence of both conditions was rising, even though downward trends were noted for the disease incidence. CONCLUSIONS: The prevalence and incidence of IBD in Poland are presented, with time trends showing a substantial increase in the disease burden over the years 2009-2020.
