Background
The International Classification of Diseases for Oncology (ICD-O) was specifically developed for coding tumours according to their site of origin (topography), microscopic appearance or histology, behaviour and grade (morphology), and is optimal for use in cancer registries. The fourth edition of the ICD-O (ICD-O-4) aims to provide an improved structure of unique codes to existent and newly defined tumour entities and has been harmonised with the International Classification of Diseases 11th Edition (ICD-11).
Methods
Based on an International Association of Cancer Registries (IACR) survey of cancer registries, over 90 % of the respondents (250 of 276) agreed to an update of ICD-O-3.2 morphology by the addition of a fifth digit to the existing four-digit histology code. Following the 5th Edition of the WHO Classification of Tumours (WCT), a beta version of ICD-O-4 was developed and disseminated for open consultation by the International Agency on Research for Cancer (IARC) on the WCT website.
Results
Following closure of the consultation period, the ICD-O-4 codes were finalized. The main changes in comparison to ICD-O-3.2 include the addition of a 5th alphanumeric digit to the histology code, changes in the first four digits of histology codes, changes of behaviour codes (e.g. pituitary adenoma code changed from /1 to /3), a new topography code for gastroesophageal junction (C16.7), detailed codes for extrahepatic bile ducts (C24.2, C24.3) and cystic duct (C24.4), change of the code for anal skin cancer from skin to anus (C44.5 to C21.3) and an optional additional digit in the topography code.
Conclusion
ICD-O-4 is compiled in consultation with pathologists, epidemiologists, public health researchers as well as the cancer registry community. The five-digit histology codes enable a hierarchical and detailed coding of tumours, while the new topography and behaviour codes reflect the evidence base on tumour aetiology, stage and behaviour.
国际肿瘤疾病分类(ICD-O)是专门根据肿瘤的起源位置(地形)、显微外观或组织学、行为和分级(形态学)对肿瘤进行编码而开发的,最适合用于癌症登记。ICD-O第四版(ICD-O-4)旨在为现有和新定义的肿瘤实体提供一种改进的独特代码结构,并已与国际疾病分类第11版(ICD-11)协调一致。方法:根据国际癌症登记处协会(IACR)对癌症登记处的调查,超过90% %的受访者(276人中的250人)同意更新ICD-O-3.2形态学,在现有的四位组织编码基础上增加第五位。继世卫组织肿瘤分类(WCT)第五版之后,制定了ICD-O-4的测试版,并在WCT网站上发布,供国际癌症研究机构(IARC)公开磋商。在咨询期结束后,ICD-O-4规范定稿。与ICD-O-3.2相比,主要变化包括组织编码增加了第5位字母数字,组织编码的前四位数字发生了变化,行为编码发生了变化(如垂体腺瘤编码从/1变为/3),胃食管交界处的新地形图编码(C16.7),肝外胆管(C24.2, C24.3)和胆囊管(C24.4)的详细编码,将肛门皮肤癌的代码从皮肤更改为肛门(C44.5至C21.3),并在地形代码中增加一个可选的附加数字。结论icd - o -4是在与病理学家、流行病学家、公共卫生研究人员以及癌症登记界协商后编制的。五位数的组织学编码能够对肿瘤进行分层和详细的编码,而新的地形和行为编码则反映了基于肿瘤病因学,阶段和行为的证据。

Quantifying cancer survival is a crucial component of cancer surveillance and control. Survival for all cancers combined is an overall summary to explore differences between population groups and over time. Net survival is the usual measure for reporting survival for all cancers combined. Differences in the cancer site distribution between groups can be adjusted for using standardization. We propose using individual weights incorporated into the Pohar Perme estimator of net survival for standardized all cancers combined survival estimates, rather than a weighted average of stratum specific estimates. This removes sparse data problems, where estimates are unobtainable for some strata. Extending to reference adjusted all-cause survival gives an alternative, interpretable measure, enabling partitioning of all-cause survival differences into those due to cancer site/age/sex distribution differences, other cause mortality differences and cancer mortality differences. We illustrate the methods using data on 749 889 individuals diagnosed with cancer in Norway 1986–2021. Using individual weights gives very similar estimates to traditional and model-based standardization and avoids using ad-hoc sparse data methods. Reference adjusted all-cause survival provides measures with simpler interpretation. For example, between 1986 and 1990 and 2016–2021 there was a 25.9 %age point improvement in 5-year all-cause survival. This improvement was partitioned into changes in the site/age/sex distribution (2.0), changes in other cause mortality rates (4.4) with the majority (19.6) due to improvements in cancer survival. Survival of all cancers combined is easily analyzed non-parametrically using individual weights. Reference adjusted all-cause survival gives a more interpretable measure improving understanding of differences over time/between groups.

<div><h3>Background</h3><div>Cancers of the oral cavity, larynx, and hypopharynx have traditionally been associated with common risk factors such as tobacco and alcohol use. With changes in smoking and drinking patterns, the incidence of these cancers is expected to change. Although the incidence of oral cavity cancer has been reported recently, there is limited evidence available for laryngeal and hypopharyngeal cancers in New Zealand (NZ). Furthermore, while growing evidence suggests increasing incidence of tongue cancer among females and young individuals, this trend has not been investigated in NZ. This study will therefore assess the incidence rates, trends in incidence, and survival of tongue, other oral cavity, laryngeal and hypopharyngeal cancers.</div></div><div><h3>Methods</h3><div>The study included patients with a primary diagnosis of squamous cell carcinoma (SCC) oral tongue, other oral cavity, larynx and hypopharynx, which were retrieved from the National Cancer Registry from 2006 to 2022. Directly age-standardised incidence rates were calculated, using the World Health Organisation standard population. Time trends were analysed with joinpoint regression to identify annual percentage changes (APCs), and overall and relative survival rates were estimated.</div></div><div><h3>Results</h3><div>The average annual incidence rate per 100,000 population was 1.2 for oral tongue SCC, 1.0 for other oral cavity SCC, 1.1 for laryngeal SCC, and 0.3 for hypopharyngeal SCC. Males consistently showed a higher incidence rate than females for all tumours except oral tongue SCC, where the incidence rates in older-aged females were higher than that of their male counterparts. Incidence rates differed by ethnicity, with Pasifika having higher incidence rates for oral tongue and other oral cavity SCC, and Māori for laryngeal and hypopharyngeal SCC, compared to European. Over the past 17 years, trends in incidence rates of laryngeal SCC declined significantly with 5 % per year overall and across all sexes, age groups and ethnic groups, whereas those of oral tongue, other oral cavity and hypopharyngeal SCC remained stable. Both overall and relative survival rates were highest for oral tongue SCC and lowest for hypopharyngeal SCC. The 5-year relative survival rates were 73 % for oral tongue SCC, 58 % for other oral cavity SCC, 67 % for laryngeal SCC and 42 % for hypopharyngeal SCC. In addition to age effects, survival outcomes varied by ethnicity, with notable disparity observed among Māori for other oral cavity and laryngeal SCC.</div></div><div><h3>Conclusion</h3><div>This study confirms a consistent decline in laryngeal SCC incidence rates in New Zealand over the last 17 years.

Background
Inequalities in adult cancer survival by sex, socio-economic position, and rural-urban residence are well established; however, evidence for childhood cancers, particularly site-specific survival, remains limited and inconsistent. This study investigated whether these inequalities exist among children diagnosed with central nervous system (CNS) cancers or neuroblastoma.
Methods
We conducted a population-based study using Victorian Cancer Registry data including 1324 children aged 0–14 years when diagnosed with CNS cancers (n = 933) or neuroblastoma (n = 391) in 1982–2021. Follow-up was conducted through linkage with death registries up to the end of 2021. Multivariable Cox regression models were used to estimate hazard ratios (HRs) for all-cause mortality in relation to sex, area-level socio-economic disadvantage, and remoteness of residence.
Results
There was weak evidence of higher mortality in males than females for both CNS cancers (HR=1.16; 95 % CI: 0.96–1.41) and neuroblastoma (HR=1.29; 95 % CI: 0.92–1.80). Survival was poorer among children living in the most disadvantaged areas (highest quintile): 54 % higher mortality for CNS cancers (HR=1.54; 95 % CI: 1.09–2.18) and 89 % higher for neuroblastoma (HR=1.89; 95 % CI: 0.99–3.61) compared to those in the least disadvantaged areas (lowest quintile). Children with neuroblastoma living outside major cities had higher mortality (HR=1.43; 95 % CI: 1.01–2.02) than those in major cities, which was attenuated (HR=1.32; 95 % CI: 0.92–1.88) after adjustment for socio-economic disadvantage.
Conclusion
Children with CNS cancers and neuroblastoma living in socio-economically disadvantaged areas experienced poorer survival outcomes. There was weaker evidence for poorer survival in males and those living outside major cities. These findings underscore the need for targeted strategies to address survival inequalities in these childhood cancers.

Emerging evidence suggests a complex bidirectional relationship between cardiovascular disease (CVD) and cancer. However, population-level data characterizing the burden of cardiovascular comorbidities at the time of cancer-attributable death remains limited. We analyzed the association between the presence of cardiovascular disease on death certificates and cancer mortality patterns across demographic groups using national mortality data from 1999 to 2020.
Methods
Using CDC WONDER multiple cause-of-death data, we analyzed records of adults ≥ 18 years with cancer as the underlying cause of death. CVD comorbidity was defined as any cardiovascular condition (ICD-10 I00-I99) listed as a contributing cause. We calculated age-adjusted mortality rates (AAMR) per 100,000 population and rate ratios, stratified by demographics and cancer types.
Results
Among 13,847,293 cancer deaths, 4521,847 (32.6 %) had cardiovascular disease listed as a contributing cause. The overall AAMR for cancer deaths with CVD was 47.75 per 100,000 (95 % CI: 47.66–47.85). Males showed higher rates than females (62.26 vs 37.22 per 100,000, rate ratio 1.67). Non-Hispanic Black populations had the highest burden (57.10 per 100,000), while Asian/Pacific Islander populations had the lowest (30.80 per 100,000). For lung cancer, mortality rates were substantially higher when CVD was present, with rate ratios ranging from 1.70 to 2.43; however, this association is likely attributable to profound unmeasured confounding by shared risk factors such as smoking.
Conclusions
Cardiovascular disease is listed as a contributing factor in nearly one-third of all cancer deaths, with distinct demographic patterns. These findings highlight the significant burden of cardiovascular comorbidities documented on death certificates at the end of life for cancer patients.

Introduction
The incidence of prostate cancer (PC) is rapidly increasing with population aging. With the emergence of new androgen receptor-targeting agents beyond androgen deprivation therapy, the treatment paradigm for PC is expected to shift. This study aimed to analyze the epidemiological characteristics and treatment patterns of patients with PC in Korea over the past decade, with a particular focus on drug utilization.
Materials and methods
We conducted a prevalence-based cross-sectional study on all Korean patients who received medical care for PC between 2011 and 2021. Patient characteristics, including age, comorbidities, metastatic status, drug classes, and treatment patterns, were analyzed.
Results
In 2021, the prevalence of PC was 532 per 100,000 adult men, an increase of 170.45 %, from 220 per 100,000 adult men in 2011. The mean age of patients with PC in 2021 was 73.07 years, with more than 80 % aged 65 years or older. Comorbidities, such as diabetes, pulmonary diseases, and mild liver disease, were common. Androgen deprivation therapy remained the most common pharmacological treatment; however, the proportion of its use gradually decreased over time, and the introduction of androgen receptor-targeting agents led to a steady increase in their use.

Background
Neuroendocrine neoplasms (NENs) are rare tumors, making up 0.5 % of all cancers, with around 65 % found in the gastroenteropancreatic (GEP) system, with increasing occurrence globally in recent years. The World Health Organization (WHO) classifies GEP-NENs into two main groups: neuroendocrine tumors and neuroendocrine carcinomas according to the new 2022 classification.
Aim
To provide updated epidemiological data on GEP-NENs diagnosed at a tertiary referral center in Beirut, Lebanon, using the WHO 2022 classification, and to describe changes in incidence, demographics, and tumor characteristics compared with previously reported data.
Methods
This retrospective study included patients treated at Hotel Dieu de France, from January 2013 to June 2024, with histologically confirmed GEP-NENs and complete medical records available. GEP-NENs were categorized based on their primary site and pathology reports reanalyzed according to the WHO 2022 classification. Data were then collected on patient demographics, primary tumor site, tumor grade and presence of metastasis at diagnosis.
Results
Among 194 NENs diagnosed during the study period, 74 were GEP-NENs (25.2 %). The mean age at diagnosis was 59.8 years, with a male-to-female ratio of 1.61. Of patients with available grading data, 39.0 % were classified as NET G1, 34.4 % as NET G2, and 26.6 % as high-grade disease (NET G3 and NEC combined). Compared with data from the previous decade, a lower proportion of G1 tumors and higher proportions of G2 and G3 tumors were observed, along with higher frequencies of pancreatic and hepatic primaries and lower rates of colonic and duodenal primaries. NET G3 and NECs were most frequently located in the liver, ampulla of Vater, and colon. All colorectal GEP-NENs identified were metastatic at diagnosis.
Conclusion
GEP-NENs in this cohort were more frequently diagnosed with higher histological grades and metastatic disease compared to the previous decade, a pattern observed during a period marked by major socioeconomic disruption and the COVID-19 pandemic.

Background
Pancreatic cancer (PC) is a malignant tumor without effective screening methods in the general population. This study aimed to develop a PC risk score to identify men at high risk for PC for early intervention.
Methods
Based on a prospective cohort study conducted in China in 2006, 90,402 men with at least two fasting blood glucose (FBG) measurements were included in this study. The PC risk model was developed using Cox regression, including the risk factors for age, total cholesterol, FBG and body mass index (BMI) change rate. The power of discrimination was examined using Harrell’s C-index and time-dependent area under curves (AUCs).
Results
During the 10-year follow-up period, 82 men developed PC (total person-years: 821,346). Age, total cholesterol level, FBG and BMI change rate were included in the final PC risk model, with a C-index of 0.754 (95 % CI 0.709–0.799). After internal validation, the AUCs of the model in different years (2, 5, 8, and 10 years) were > 0.700 in all men and in men without diabetes. In the derived scoring system (score range:-2–10), there was an approximately 40 % increased risk (Hazard ratio, 1.415; 95 % CI, 1.291–1.550) with every 1-point increase. Participants with the top 20 % scores (6–10 points) had a 30-fold increased risk of PC compared with individuals in the lowest score group (-2 – -1 points).
Conclusions
A scoring system for identifying high-risk men with PC was developed, which may be helpful for early detection and intervention of PC in the future.

Background
Higher serum insulin-like growth factor 1 (IGF-1) has been linked to colorectal cancer (CRC), with evidence supporting increased risk for colon but not rectal tumors. Few studies have included substantial numbers of non-Hispanic Black individuals, who have elevated population-level CRC risk. We investigated associations between IGF-1 and CRC in the Southern Community Cohort Study. We also report associations with IGF binding protein 3 (IGFBP-3), the primary IGF-1 transporter, and the IGF-1/IGFBP-3 ratio (a surrogate marker for biologically available IGF-1).
Methods
Participants with incident CRC (N = 297) were individually matched with controls (N = 604) on age, race, and sex. The majority of the cohort reports Black racial identity (75 %). Serum IGF-1 and IGFBP-3 were measured at enrollment. Logistic regression was used to estimate odds ratios (ORs) with 95 % confidence intervals (CIs) for CRC, colon and rectal cancers.
Results
For higher IGF-1 (tertile 3vs1), the OR for CRC was 1.45 (CI 0.95–2.21). Higher IGF-1 was associated with greater odds for colon cancer (OR 1.64, CI 1.01–2.64) but not rectal cancer (OR 0.93, CI 0.43–1.97). The associations with CRC and colon cancer were consistent among participants who fasted prior to serum draw (N = 356, CRC: OR 1.89, CI 0.95–3.78; colon cancer: OR 2.08, CI 0.96–4.51). No associations were observed for IGFBP-3 or the IGF-1/IGFBP-3 ratio in the full sample.
Conclusion
Higher IGF-1 was associated with increased odds for colon cancer, but not rectal cancer, among predominantly non-Hispanic Black individuals with lower socioeconomic status, consistent with findings from predominantly non-Hispanic White cohorts.
高血清胰岛素样生长因子1 (IGF-1)与结直肠癌(CRC)有关,有证据支持结肠肿瘤风险增加,而非直肠肿瘤。很少有研究包括大量非西班牙裔黑人,他们有较高的人群CRC风险。我们在南部社区队列研究中调查了IGF-1与CRC之间的关系。我们还报道了与IGF结合蛋白3 (IGFBP-3)、主要IGF-1转运蛋白和IGF-1/IGFBP-3比率(生物可用性IGF-1的替代标记物)的关联。方法将发生CRC的参与者(N = 297)与对照组(N = 604)在年龄、种族和性别上进行单独匹配。大多数队列报告黑人种族身份(75% %)。入组时测定血清IGF-1和IGFBP-3。采用Logistic回归估计CRC、结肠癌和直肠癌的比值比(ORs),置信区间为95% %。结果高IGF-1组CRC的OR为1.45 (CI 0.95 ~ 2.21)。较高的IGF-1与结肠癌(OR 1.64, CI 1.01-2.64)相关,但与直肠癌(OR 0.93, CI 0.43-1.97)无关。在血清抽血前禁食的参与者中,结直肠癌和结肠癌的相关性是一致的(N = 356,结直肠癌:OR 1.89, CI 0.95-3.78;结肠癌:OR 2.08, CI 0.96-4.51)。在整个样本中没有观察到IGFBP-3或IGF-1/IGFBP-3比值的关联。结论:在社会经济地位较低的非西班牙裔黑人中,较高的IGF-1与结肠癌的发病率增加有关,但与直肠癌无关,这与非西班牙裔白人人群的研究结果一致。
