Alcohol use is causally linked to multiple cancers. We present global, regional, and national estimates of alcohol-attributable cancer burden in 2020 to inform alcohol policy and cancer control ...across different settings globally.
In this population-based study, population attributable fractions (PAFs) calculated using a theoretical minimum-risk exposure of lifetime abstention and 2010 alcohol consumption estimates from the Global Information System on Alcohol and Health (assuming a 10-year latency period between alcohol consumption and cancer diagnosis), combined with corresponding relative risk estimates from systematic literature reviews as part of the WCRF Continuous Update Project, were applied to cancer incidence data from GLOBOCAN 2020 to estimate new cancer cases attributable to alcohol. We also calculated the contribution of moderate (<20 g per day), risky (20–60 g per day), and heavy (>60 g per day) drinking to the total alcohol-attributable cancer burden, as well as the contribution by 10 g per day increment (up to a maximum of 150 g). 95% uncertainty intervals (UIs) were estimated using a Monte Carlo-like approach.
Globally, an estimated 741 300 (95% UI 558 500–951 200), or 4·1% (3·1–5·3), of all new cases of cancer in 2020 were attributable to alcohol consumption. Males accounted for 568 700 (76·7%; 95% UI 422 500–731 100) of total alcohol-attributable cancer cases, and cancers of the oesophagus (189 700 cases 110 900–274 600), liver (154 700 cases 43 700–281 500), and breast (98 300 cases 68 200–130 500) contributed the most cases. PAFs were lowest in northern Africa (0·3% 95% UI 0·1–3·3) and western Asia (0·7% 0·5–1·2), and highest in eastern Asia (5·7% 3·6–7·9) and central and eastern Europe (5·6% 4·6–6·6). The largest burden of alcohol-attributable cancers was represented by heavy drinking (346 400 46·7%; 95% UI 227 900–489 400 cases) and risky drinking (291 800 39·4%; 227 700–333 100 cases), whereas moderate drinking contributed 103 100 (13·9%; 82 600–207 200) cases, and drinking up to 10 g per day contributed 41 300 (35 400–145 800) cases.
Our findings highlight the need for effective policy and interventions to increase awareness of cancer risks associated with alcohol use and decrease overall alcohol consumption to prevent the burden of alcohol-attributable cancers.

Hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA) are the two main histological subtypes of primary liver cancer. Estimates of the burden of liver cancer by subtype are needed ...to facilitate development and evaluation of liver cancer control globally. We provide worldwide, regional and national estimates of HCC and iCCA incidence using high-quality data.
We used population-based cancer registry data on liver cancer cases by histological subtype from 95 countries to compute the sex- and country-specific distributions of HCC, iCCA and other specified histology. Subtype distributions were applied to estimates of total liver cancer cases for 2018 from the Global Cancer Observatory. Age-standardised incidence rates (ASRs) were calculated.
There were an estimated 826,000 cases of liver cancer globally in 2018: 661,000 HCC (ASR 7.3 cases per 100,000); 123,000 iCCA (ASR 1.4) and 42,000 other specified histology (ASR 0.5). HCC contributed 80% of the world total liver cancer burden followed by iCCA (14.9%) and other specified histology (5.1%). HCC rates were highest in Eastern Asia (ASR 14.8), Northern Africa (ASR 13.2) and South-Eastern Asia (ASR 9.5). Rates of iCCA were highest in South-Eastern Asia (ASR 2.9), Eastern Asia (ASR 2.0), Northern Europe, the Caribbean and Central America and Oceania (ASR all 1.8).
We have shown the importance of uncovering the distinct patterns of the major subtypes of liver cancer. The use of these estimates is critical to further develop public health policy to reduce the burden of liver cancer and monitor progress in controlling HCC and iCCA globally.
•Liver cancer is the third cause of cancer death worldwide and has two major subtypes.•Cancer registry data were used to estimate regional liver cancer subtype distribution.•Hepatocellular carcinoma contributed 80% of all liver cancer cases globally.•Intrahepatic cholangiocarcinoma contributed 15% of all liver cancer cases globally.•Considering histological subtypes is essential to assess global liver cancer burden.
Regarding the continuous changes in the diagnostic process and treatment of colorectal cancer (CRC), it is important to evaluate long‐term trends which are relevant in giving direction for further ...research and innovations in cancer patient care. The aim of this study was to analyze developments in incidence, treatment and survival for patients diagnosed with CRC in the Netherlands. For this population‐based retrospective cohort study, all patients diagnosed with CRC between 1989 and 2014 in the Netherlands were identified using data of the nationwide population‐based Netherlands Cancer Registry (n = 267,765), with follow‐up until January 1, 2016. Analyses were performed for trends in incidence, mortality, stage distribution, treatment and relative survival measured from the time of diagnosis. The incidence of both colon and rectal cancer has risen. The use of postoperative chemotherapy for Stage III colon cancer increased (14–60%), as well as the use of preoperative (chemo)radiotherapy for rectal cancer (2–66%). The administration of systemic therapy and metastasectomy increased for Stage IV disease patients. The 5‐year relative survival increased significantly from 53 to 62% for colon cancer and from 51 to 65% for rectal cancer. Ongoing advancements in treatment, and also improvement in other factors in the care of CRC patients—such as diagnostics, dedicated surgery and pre‐ and postoperative care—lead to a continuous improvement in the relative survival of CRC patients. The increasing incidence of CRC favors the implementation of the screening program, of which the effects should be monitored closely.
What's new?
To best inform new directions for cancer management, it's important to study historical trends. Here, the authors analyzed 25 years of data in The Netherlands on colorectal cancer incidence, treatment and survival. During the period from 1989 to 2014, both incidence and 5‐year relative survival increased. Certain treatments also became more common, such as postoperative chemotherapy for Stage III patients and systemic therapy and surgical removal of metastases for Stage IV patients. Improved diagnostics and treatments have helped more patients survive, and the rising incidence of CRC supports the use of the nationwide screening program, introduced by the Dutch government in 2014.
Highlights • One fifth of operated colorectal cancer patients will develop metachronous metastases. • Colon and rectal cancer patients have different patterns of metastatic spread. • Median time to ...diagnosis depends on site of metastasis. • The risk for metastases is associated with patient and tumour characteristics.
...hospitals might have postponed diagnostic evaluation or have longer turnaround times for diagnostic evaluation because many hospital-based resources are being allocated to tackle COVID-19. ......national screening programmes for breast, colorectal, and cervical cancer are temporarily halted as of March 16, 2020, to alleviate the demand on the health-care system due to COVID-19. ...misconceptions were eliminated about a heightened risk of contracting COVID-19 in a health-care setting because of inadequate policies for infection control at the institutional level and resource constraints in the delivery of essential oncological care.
Peritoneal carcinomatosis (PC) is an important cause of morbidity and mortality among patients with gastric cancer. The aim of the current study was to provide reliable population‐based data on the ...incidence, risk factors and prognosis of PC of gastric origin. All patients diagnosed with gastric cancer in the area of the Eindhoven Cancer Registry between 1995 and 2011 were included. Incidence and survival were computed and risk factors for peritoneal carcinomatosis were determined using multivariate logistic regression analysis. In total, 5,220 patients were diagnosed with gastric cancer, of whom 2,029 (39%) presented with metastatic disease. PC was present in 706 patients (14%) of whom 491 patients (9%) had PC as the only metastatic site. Younger age (<60 years), female gender, advanced T‐ and N‐stage, primary tumor of signet ring cells or linitis plastica and primary tumors covering multiple anatomical locations of the stomach were all associated with a higher odds ratios of developing PC. Median survival of patients without metastases was 14 months, but only 4 months for patients with PC. PC is a frequent condition in patients presenting with gastric cancer, especially in younger patients with advanced tumor stages. Given the detrimental influence of PC on survival, efforts should be undertaken to further explore the promising results that were obtained in preventing or treating this condition with multimodality strategies.
What's new?
Until recently, peritoneal carcinomatosis (PC), in which malignant ascites forms in the peritoneum, was considered to be an untreatable condition. But new treatment options have raised hope for improved survival, as well as created a need to better understand risk factors and prevention. Here, analysis of data from the Eindhoven Cancer Registry from 1995–2011 reveals that more than one‐third of patients with metastatic gastric cancer presented with PC. Younger patients and females with advanced disease were at greatest risk for this condition. The findings may have implications for PC diagnosis and treatment.
Abstract Background Upcoming mass screening for colorectal cancer (CRC) makes a review of recent literature on the association with socioeconomic status (SES) relevant, because of marked and ...contradictory associations with risk, treatment and outcome. Methods The Pubmed database using the MeSH terms ‘Neoplasms’ or ‘Colorectal Neoplasms’ and ‘Socioeconomic Factors’ for articles added between 1995 and 1st October 2009 led to 62 articles. Results Low SES groups exhibited a higher incidence compared with high SES groups in the US and Canada (range risk ratio (RR) 1.0–1.5), but mostly lower in Europe (RR 0.3–0.9). Treatment, survival and mortality all showed less favourable results for people with a lower socioeconomic status: Patients with a low SES received less often (neo)adjuvant therapy (RR ranging from 0.4 to 0.99), had worse survival rates (hazard ratio (HR) 1.3–1.8) and exhibited generally the highest mortality rates up to 1.6 for colon cancer in Europe and up to 3.1 for rectal cancer. Conclusions A quite consistent trend was observed favouring individuals with a high SES compared to those with a low SES that still remains in terms of treatment, survival and thus also mortality. We did not find evidence that the low/high SES gradients for treatment chosen and outcome are decreasing. To meet increasing inequalities in mortality from CRC in Europe for people with a low SES and to make mass screening successful, a high participation rate needs to be realised of low SES people in the soon starting screening program.
Abstract Background High hospital volume is associated with better outcomes after oesophagectomy and gastrectomy. In the Netherlands, a minimal volume standard of 10 oesophagectomies per year was ...introduced in 2006. For gastrectomy, no minimal volume standard was set. Aims of this study were to describe changes in hospital volumes, mortality and survival and to explore if high hospital volume is associated with better outcomes after oesophagectomy and gastrectomy in the Netherlands. Methods From 1989 to 2009, 24,246 patients underwent oesophagectomy ( N = 10,025) or gastrectomy ( N = 14,221) in the Netherlands. Annual hospital volumes were defined as very low (1–5), low (6–10), medium (11–20), and high (⩾21). Volume–outcome analyses were performed using Cox regression, adjusting for year of diagnosis, case-mix and the use of multi-modality treatment. Results From 1989 to 2009, the percentage of patients treated in high-volume hospitals increased for oesophagectomy (from 7% to 64%), but decreased for gastrectomy (from 8% to 5%). Six-month mortality (from 15% to 7%) and 3-year survival (from 41% to 52%) improved after oesophagectomy, and to a lesser extent after gastrectomy (6-month mortality: 15%-10%, three-year survival: 55–58%). High hospital volume was associated with lower 6-month mortality (hazard ratio (HR) 0.48, P < 0.001) and longer 3-year survival (HR 0.77, P < 0.001) after oesophagectomy, but not after gastrectomy. Conclusions Oesophagectomy was effectively centralised in the Netherlands, improving mortality and survival. Gastrectomies were mainly performed in low volumes, and outcomes after gastrectomy improved to a lesser extent, indicating an urgent need for improvement in quality of surgery and perioperative care for gastric cancer in the Netherlands.
Abstract
Background
Discussing patients with cancer in a multidisciplinary team meeting (MDTM) is customary in cancer care worldwide and requires a significant investment in terms of funding and ...time. Efficient collaboration and communication between healthcare providers in all the specialisms involved is therefore crucial. However, evidence-based criteria that can guarantee high-quality functioning on the part of MDTMs are lacking. In this systematic review, we examine the factors influencing the MDTMs’ efficiency, functioning and quality, and offer recommendations for improvement.
Methods
Relevant studies were identified by searching Medline, EMBASE, and PsycINFO databases (01–01-1990 to 09–11-2021), using different descriptions of ‘MDTM’ and ‘neoplasm’ as search terms. Inclusion criteria were: quality of MDTM, functioning of MDTM, framework and execution of MDTM, decision-making process, education, patient advocacy, patient involvement and evaluation tools. Full text assessment was performed by two individual authors and checked by a third author.
Results
Seventy-four articles met the inclusion criteria and five themes were identified: 1) MDTM characteristics and logistics, 2) team culture, 3) decision making, 4) education, and 5) evaluation and data collection. The quality of MDTMs improves when the meeting is scheduled, structured, prepared and attended by all core members, guided by a qualified chairperson and supported by an administrator. An appropriate amount of time per case needs to be established and streamlining of cases (i.e. discussing a predefined selection of cases rather than discussing every case) might be a way to achieve this. Patient centeredness contributes to correct diagnosis and decision making. While physicians are cautious about patients participating in their own MDTM, the majority of patients report feeling better informed without experiencing increased anxiety. Attendance at MDTMs results in closer working relationships between physicians and provides some medico-legal protection. To ensure well-functioning MDTMs in the future, junior physicians should play a prominent role in the decision-making process. Several evaluation tools have been developed to assess the functioning of MDTMs.
Conclusions
MDTMs would benefit from a more structured meeting, attendance of core members and especially the attending physician, streamlining of cases and structured evaluation. Patient centeredness, personal competences of MDTM participants and education are not given sufficient attention.
We aimed to improve our understanding of the epidemiology of squamous cell carcinoma and adenocarcinoma of the esophagus.
We estimated average annual percent change and analyzed age-period-cohort ...trends on population-based cancer data.
We found decreases in squamous cell carcinoma incidence in half of male populations (largest decrease in US black males average annual percent change -7.6) and increases in adenocarcinoma incidence in nearly a third of populations. Trends may be associated with a mix of birth cohort and period effects.
More complete data and evidence are needed to conclude the reasons for the observed trends (see Visual Abstract, Supplementary Digital Content 4, http://links.lww.com/AJG/B823).
