Italy, home to one of the world’s oldest populations, has traditionally shown geographic differences in cancer incidence, with rates decreasing from north to south. The cancer registries that have been accredited by the Italian Cancer Registry Network (AIRTUM), during the last 20 years altogether cover the 90 % of the Italian population, aiming to improve data quality, standardize procedures, and promote research. This study presents the methodological approaches used for data collection, quality control, and analysis to describe current patterns of cancer incidence, mortality, and survival across Italy's three macro-areas (North, Central, South). Estimates of incidence rates and case numbers for 2025 were also produced. Data from 34 accredited cancer registries were analyzed, comprising over 4.6 million cases from 1981 to 2020, with a detailed focus on the 2008–2017 period, which includes over 3 million cases. Cancer incidence and mortality data were collected according to ICD-O-3 and ICD-10 classifications and processed for statistical analysis using tools such as SEERPrep, SEERStat, and the Joinpoint Regression Program. Age-standardized rates were calculated, and incidence and mortality trends from 2013 to 2017 were modeled. Five-year cumulative net survival was estimated using the Pohar-Perme method to adjust for competing risks. Survival trends were analyzed by geographic areas and cancer sites, revealing regional disparities in cancer outcomes.

Occupational benzene exposure is a known carcinogen; however, the dose-response relationship with cancers of the nervous system, particularly glioma, requires clarification. Based on the systematic review by Mangiaterra et al., this paper conducted a secondary analysis of the results and utilized original supplementary data to assess risk ratios (RRs) for high, medium, and low benzene exposure levels. This aimed to evaluate both linear and non-linear dose-response relationships. We observed a significantly increased risk for nervous system cancers only at high exposure levels. Risks associated with moderate and low exposure levels showed no significant increase. Both dose-response curves indicated no clear upward trend with increasing exposure. Limitations include the frequent lack of confounder adjustment in source estimates, potential publication bias, and limited original data, all of which impact the heterogeneity and accuracy of the findings. While high-concentration benzene exposure may pose a risk for nervous system cancers and potentially exhibit dose-dependency, these limitations constrain the robustness of the dose-response assessment. Future research should validate this association using high-quality, multi-level exposure data with adequate confounder adjustment. Such studies are crucial to provide a scientific basis for occupational health protection measures.

Background
Sleep traits may influence cancer risk; however, their associations with prostate (PCa), endometrial (ECa), and epithelial ovarian (EOCa) cancer remain unclear.
Methods
We conducted an observational analysis using the UK Biobank cohort and a two-sample Mendelian randomisation (MR) analysis to investigate the association between six sleep traits-duration, chronotype, insomnia, daytime napping, daytime sleepiness, and snoring-with PCa, ECa, and EOCa risk. Cox proportional hazards models were used for the observational analysis, while the inverse variance-weighted (IVW) method was applied in MR, with multiple sensitivity analyses. A Bonferroni correction was applied to account for multiple testing.
Results
Among 8608 PCa, 1079 ECa, and 680 EOCa incident diagnoses (median follow-up: 6.9 years), snoring was associated with reduced EOCa risk (HR=0.78, 95 %CI: 0.62–0.98), while daytime sleepiness was associated with increased EOCa risk (HR=1.23, 95 %CI: 1.03–1.47). However, these associations were not confirmed in MR. MR suggested higher odds of PCa (ORIVW=1.05, 95 %CI: 1.01–1.11) and aggressive PCa (ORIVW=1.10, 95 %CI: 1.02–1.19) for evening compared to morning chronotype. None of the findings survived multiple testing correction.
Conclusion
Sleep traits were not associated with PCa, ECa, or EOCa risk; however, an evening chronotype may increase PCa risk. Further research is needed to verify this association and investigate potential underlying mechanisms.

Background
The predictive performance of a colorectal cancer (CRC) risk prediction model incorporating genome-wide polygenic risk scores (PRSs) and lifestyle factors remains unclear in Asian populations. This study aimed to develop and evaluate the Asian-specific models using a Japanese population-based prospective study.
Methods
We derived 31 genome-wide PRSs using a genome-wide association study of CRC from the Biobank Japan and selected the best-performing PRS with the highest C-index in development case-cohort, including 200 incident cases. In evaluation case-cohort, including 693 incident cases, we assessed the discrimination accuracy (C-index, integrated discrimination improvement (IDI), and net reclassification improvement (NRI)) of lifestyle, PRS, and combined models using 5-fold cross-validation methods and estimated 10-year absolute risk.
Results
Of the 31 derived PRSs, the PRS aggregating 104,677 variant risks performed best in the development case-cohort. The men and women in the highest quintiles of the PRS had an approximately three-fold and two-fold higher risk of CRC, respectively, than those in the lowest in the evaluation case-cohort. Meanwhile, the association of lifestyle factors with CRC risk was observed only in men. Incorporating the PRS into a lifestyle model improved the C-index from 0.64 to 0.66 for men and from 0.61 to 0.63 for women. The IDI and NRI values supported this improvement. The 10-year absolute risk was 3.3 % and 1.6 % for high-risk men and women, respectively, and 0.5 % for both low-risk men and women.
Conclusions
This study suggests that the CRC risk prediction model utilizing genome-wide PRS for Asians is valuable; however, further improvement is needed before clinical implementation.

Background
The prevalence of type 2 diabetes (T2D) has increased worldwide during the 21st century. T2D and colorectal cancers (CRC) share risk factors such as obesity. This study aims to estimate the association between T2D and the incidence of primary CRC, and furthermore the association of diabetic complications with the risk of CRC.
Methods
We linked exposure data on T2D by severity (presence or absence of complications), overweight and obesity and alcohol related disorders from Care Register for Health Care and CRC cases from the Finnish Cancer Registry to a random sample of 2.5 million Finnish individuals of all ages that were followed from 2000 to 2017. To account for the cumulative burden of exposures, we employed a multi-state model where transition rates to CRC were modeled with Poisson regression, adjusted for age, calendar period, sex, overweight and obesity and alcohol related disorders.
Results
The cohort included 171,789 people diagnosed with T2D, with a median age of 67.6 at diagnosis. From the 23 533 CRCs diagnosed in the entire cohort, 2430 were in people with diabetes. Individuals diagnosed with T2D were at a higher risk of CRC (Hazard ratio 1.26, 95 % confidence interval 1.20–1.32). Persons with diabetic complications had a higher risk of CRC than those without complications after 10 years since the initial T2D diagnosis (1.21, 1.02–1.45, p = 0.033). Men with diabetic nephropathy had a significantly higher risk of CRC (1.51, 1.23–1.86) than men with diabetes without nephropathy.
Conclusion
Our research shows that people with uncomplicated T2D are at an increased risk of CRC in the first 10 years after T2D diagnosis. The risk of CRC among individuals with complicated T2D remains elevated also in longer term follow-up.

Background
Early detection of colorectal cancer (CRC) significantly improves survival. However, geographic inaccessibility of colonoscopies may prevent timely and effective screenings. The relationship between spatial access to colonoscopy providers, social determinants of health, and stage at CRC diagnosis remains understudied. We evaluated how place-based factors and individual characteristics are related to CRC diagnosis stage.
Methods
This cross-sectional, population-based study includes all CRC patients aged 50–84 at diagnosis between 2010 and 2021 from the Maryland Department of Health’s Cancer Registry (n = 21,599). We measured the spatial (geographic) accessibility to colonoscopy providers across Maryland at the census tract level using the Enhanced Two-Step Floating Catchment Area (E2SFCA) method. Multilevel logistic regression models were used to examine associations between late-stage CRC diagnosis and spatial accessibility, four census tract-level social vulnerability themes, rurality, and individual-level covariates.
Results
Among colorectal cancer cases with known stage (n = 19,239), 63.2 % (n = 12,151) were diagnosed at late-stage. Increasing socioeconomic vulnerability quartiles were associated with greater odds of late-stage diagnosis (Q4 vs Q1: OR, 1.17; 95 % CI, 1.04–1.32), while rural residence was associated with lower odds (OR, 0.69; 95 % CI, 0.59–0.80). Geographic access to colonoscopy providers was not significantly associated with late-stage diagnosis.
Conclusion
Findings suggest that non-spatial accessibility factors and place-based social determinants of health are more important than geographic access alone in influencing risk of late-stage colorectal cancer diagnosis. Public health interventions in Maryland should aim to target communities of high social vulnerability, particularly those with low socioeconomic status. Although our analysis is limited to Maryland, the results are broadly consistent with similar studies across U.S. settings and may be relevant in other states. Future studies should examine the barriers to CRC screening and diagnosis beyond geographic access.

Background
Pharyngeal squamous cell carcinoma has been linked to later squamous cell carcinoma of the esophagus, but it is unclear if risks are similar to that of Barrett’s esophagus and would justify routine gastroscopy surveillance.
Method
Data on pharyngeal and esophageal cancers in 1980–2016 were retrieved through histopathology reports from Sweden’s 28 pathology departments and linked to national population-based healthcare registers. We calculated hazard ratios (HRs) for esophageal cancer and death in patients with pharyngeal carcinoma compared to a matched general population, and in a secondary analysis also compared to siblings of patients.
Results
We identified 1055 adults with pharyngeal cancer without prior or concomitant cancer. 78 % were men and median age at diagnosis of pharyngeal cancer was 64 years. During a median follow-up of 2.5 years four (0.4 %) patients developed esophageal squamous cell carcinoma, equal to 1 in 263 patients (HR = 14.3; 95 % CI = 1.6–132.3). In a competing risk analysis, the risk estimate for ESCC dropped and did not attain statistical significance (subdistribution HR=1.9 (95 % CI=0.7–5.2)). Some 855 patients (81 %) died during follow-up, representing a 7.7-fold increased risk of death among patients with pharyngeal cancer (Cox regression: HR=7.7; 95 % CI = 6.8–8.6).
Conclusion
The yearly risk of developing esophageal squamous cell carcinoma was 0.07 %. This is lower than in Barrett’s esophagus and argues against long-term endoscopic surveillance among patients with pharyngeal cancer.

咽部鳞状细胞癌与后来的食管鳞状细胞癌有关,但尚不清楚其风险是否与Barrett食管相似,是否有必要进行常规胃镜检查。方法通过瑞典28个病理科室的组织病理学报告检索1980-2016年咽癌和食管癌的数据,并与全国人口卫生保健登记册相关联。我们计算了咽癌患者与匹配的一般人群相比食管癌和死亡的风险比(hr),并在二次分析中与患者的兄弟姐妹进行了比较。结果我们确定了1055例没有既往或合并癌症的咽喉癌成人患者。78 %为男性,诊断咽喉癌时的中位年龄为64岁。在中位随访2.5年期间,4例(0.4 %)患者发生食管鳞状细胞癌,相当于263例患者中有1例(HR = 14.3;95 % ci = 1.6-132.3)。在竞争风险分析中,ESCC的风险估估值下降,没有达到统计学意义(亚分布HR=1.9(95 % CI= 0.7-5.2))。随访期间约有855名患者(81% %)死亡,咽癌患者的死亡风险增加了7.7倍(Cox回归:HR=7.7;95 % ci = 6.8-8.6)。结论食管癌的年发病风险为0.07 %。这比巴雷特食管低,因此反对在咽癌患者中进行长期内窥镜检查。证据水平

Background
Acute leukaemia (AL) is an aggressive haematological cancer. This study investigated patient factors in unplanned diagnostic pathways and the association with the prognosis and mortality of patients.
Methods
This nationwide register-based study included all patients diagnosed with AL in Denmark in 2014–2018. Diagnostic pathways were divided into elective pathways and unplanned pathways (acute admission within up to 30 days before diagnosis and no planned admissions).
Results
We included 1495 patients with AL. Diagnostic pathway did not differ by sociodemographic characteristics. Patients with a WHO performance score of 2–4 had a 64 % probability of being diagnosed in an unplanned pathway (95 % confidence interval (CI) 59–69 %) versus 47 % (95 % CI 44–50 %) in patients with a WHO performance score of 0–1. High comorbidity level was associated with higher probability of unplanned pathways. Patients in unplanned pathways had lower one-year survival than patients in elective pathways (adjusted all-cause mortality hazard ratio: 1.44 (95 % CI 1.29–1.62). This survival difference disappeared in landmark analyses with three-month delayed entry.
Conclusions
Patients with impaired performance score and high comorbidity level more often experienced an unplanned diagnostic pathway. Unplanned pathway was associated with lower survival and death within 3 months after the diagnosis.
背景:急性白血病(AL)是一种侵袭性血液学癌症。本研究探讨了非计划诊断途径中的患者因素及其与患者预后和死亡率的关系。方法:这项基于全国登记的研究纳入了2014-2018年丹麦所有诊断为AL的患者。诊断途径分为选择性途径和非计划途径(诊断前30天内急性入院和无计划入院)。结果我们纳入了1495例AL患者,诊断途径没有因社会人口学特征而异。世卫组织绩效评分为2-4的患者在计划外途径中被诊断的概率为64% %(95 %可信区间(CI) 59-69 %),而世卫组织绩效评分为0-1的患者为47 %(95 % CI 44-50 %)。高合并症水平与计划外途径的可能性较高相关。非计划路径患者的一年生存率低于选择路径患者(调整后全因死亡率风险比:1.44(95 % CI 1.29-1.62)。这种生存差异在延迟3个月进入的里程碑分析中消失。结论成绩评分低、合并症发生率高的患者更易出现计划外诊断途径。非计划途径与诊断后3个月内较低的生存率和死亡率相关。

Background
This study aimed to investigate the COVID-19 impact on invasive breast cancer incidence and one-year survival in Ireland.
Methods
Anonymised aggregate population data from the National Cancer Registry Ireland were used to examine incidence between 2014 and 2020 and differences in the distribution of clinical characteristics using chi-squared tests. Negative binomial regression examined the association between incidence and year of diagnosis. One-year survival was examined by year of diagnosis using Cox proportional hazards regression modelling.
Results
For 2020, the age-standardised incidence rate (ASR, per 100,000 females) was 131.9, compared to 163.9 for 2019. In 2020, the incidence rate significantly declined (IRR = 0.41, 95 % CI = 0.22, 0.75) relative to 2019. Fewer cases presented through organised screening (-62.3 %), while similar or increased numbers presented with symptoms (0.1 %) and via other methods (9.0 %) respectively in 2020, compared to 2019. Significant differences were observed in case distribution by ER status (p = 0.02) and stage (p < 0.01) between 2019 and 2020. One-year survival was similar for cases diagnosed during 2014–2019 and in 2020 (HR = 1.07, 95 % CI = 0.89, 1.27).
Conclusions
These findings demonstrate reductions in invasive breast cancer incidence and no difference in one-year survival following the pandemic onset. Additional studies to determine the longer-term COVID-19 impact are needed.
