National Cancer Center (NCC) of China annually reports the nationwide statistics for cancer incidence and mortality using population-based cancer registry data from all available cancer registries in ...China.
There were a total of 487 registries which reported high quality data of cancer incidence and mortality across China in 2016. The nationwide numbers of new cancer cases and deaths were estimated using the pooled cancer registry data, which were stratified by area (urban/rural), sex, age group (0, 1-4, 5-9, 10-14…85+) and cancer site for incidence and mortality, and then multiplied by corresponding national population. The world Segi's population was applied for the calculation of age-standardized rates.
About 4,064,000 new cancer cases and 2,413,500 new cancer deaths occurred in China in 2016. Cancers of the lung, colon-rectum, stomach, liver and female breast were the top five common cancers, accounting for 57.4% of total cancer new cases. Cancers of the lung, liver, stomach, colon-rectum and esophagus were the five leading causes of cancer deaths, accounting for 69.3% of total cancer deaths. The crude and age-standardized incidence rates (ASIR) were 293.91 and 186.46 per 100,000 population, respectively. The crude mortality rate was 174.55/100,000 and the age-standardized mortality rate (ASMR) was 105.19/100,000. The ASIR was higher but the ASMR was lower in urban areas than that in rural areas. In past decades, the ASIR was relatively stable in males, but significantly increased by about 2.3% per year in females for overall cancers combined. In contrast, the ASMR significantly decreased by about 1.2% per year for both sexes during 2000-2016. Notably, the cancer-specific ASIR and ASMR of esophageal, stomach, and liver cancers decreased significantly, whereas both rates for cancers of the colon-rectum, prostate, female breast, cervix, and thyroid increased significantly.
Cancer remains a major public health problem in China, which demands long-term collaborative efforts of a broad community. With the national guideline on cancer prevention and control, tailored cancer prevention and control programs are needed in different regions to help reduce the burden of these highly fatal diseases in China.

Rare cancers collectively account for a significant proportion of the overall cancer burden in Japan. We aimed to describe and examine the incidence of each rare cancer and the temporal changes using ...the internationally agreed rare cancer classification. Cancer cases registered in regional population‐based cancer registries from 2011 to 2015 and the National Cancer Registry (NCR) from 2016 to 2018 were classified into 18 families, 68 Tier‐1 cancer groupings, and 216 single cancer entities based on the RARECAREnet list. Crude incidence rates and age‐standardized incidence rates (ASR) were calculated for Tier‐1 and Tier‐2 cancers. The annual percent change and the 95% and 99% confidence limits for annual ASR for each of the 68 Tier‐1 cancers were estimated using the log‐linear regression of the weighted least squares method. The differences in ASRs between 2011 and 2018 were evaluated as an absolute change. A total of 5,640,879 cases were classified into Tier‐1 and Tier‐2 cancers. The ASRs of 18 out of 52 Tier‐1 cancers in the rare cancer families increased, whereas the ASR for epithelial tumors of gallbladder decreased. The ASRs of 6 out of the 16 Tier‐1 cancers in the common cancer families increased, whereas those of epithelial tumors of stomach and liver decreased. There was no significant change in the incidence of the other 40 Tier‐1 cancers. The incidence of several cancers increased due to the dissemination of diagnostic concepts, improved diagnostic techniques, changes in coding practice, and the initiation of the NCR.

The Taiwan Cancer Registry (TCR) is a nationwide population-based registry that collects the data of patients with newly diagnosed cancer from hospitals with ≥50 beds. TCR data are high quality in ...terms of completeness and timeliness. However, accuracy is also a crucial quality indicator. This study evaluated the accuracy rates of selected 55 major items in the long-form TCR data between 2014 and 2016 with 700 reported cases randomly selected from 25 long-form-reporting hospitals. We calculated the accuracy rates of the reported data by employing a reabstracted chart review. Among the 55 items, the accuracy rates of 38 (69%) were at least 95%, those of 10 (18%) were between 90% and 95%, those of 5 (9%) were between 85% and 90%, and the remaining 2 (4%) were between 80% and 85%. This demonstrates a high degree of accuracy in the TCR long-form data.

Population-based data on the incidence of frequent colorectal metastases are fairly scarce, while that on rare metastatic sites are lacking.
The aim of this study was to provide epidemiological ...indicators of metastatic sites frequency in patients with colorectal cancer.
Incidence was modelled using Poisson and Joinpoint regressions in a population-based cancer registry study including metastatic colorectal cancers diagnosed between 1991 and 2020 (N = 5,199). Tumor molecular markers were collected for the 2016–2020 period.
Liver, peritoneum, lung and bone were the most frequent metastatic sites. Among frequent sites, incidence of liver and lung sites decreased in men respectively since 1999 and 2010, whereas in women incidence of liver and peritoneum sites increased steadily throughout the whole period. Each of the other sites concerned less than 3% of metastatic colorectal cancer cases and presented standardized incidence rates between 0.19 and 1.39 per 1,000,000. Among rare sites, incidence of adrenal glands, supraclavicular lymph node, mediastinum and ascites had doubled in 2016–2020 as compared to the 25 previous years. BRAFV600E variant was more frequent in presence of carcinomatosis, and absence of liver and lung metastasis while KRAS variant was more frequent in presence of lung metastasis.
This study provides unprecedented incidence indicators for rare synchronous metastases of colorectal cancer.

Breast cancer (BC) is the leading cause of cancer in sub‐Saharan Africa (SSA) with rapidly increasing incidence rates reported in Uganda and Zimbabwe. However, the magnitude of these rising trends in ...premenopausal and postmenopausal women is unknown in most African countries. We used data from the African Cancer Registry Network on incident breast cancers in women from 11 population‐based cancer registries in 10 countries representing each of the four SSA regions. We explored incidence changes among women before and after age 50 by calendar period and, where possible, generational effects in this unique sub‐Saharan African cohort. Temporal trends revealed increasing incidence rates in all registries during the study period, except in Nairobi where rates stabilised during 2010 to 2014 after rapidly increasing from 2003 to 2010 (APC = 8.5 95%, CI: 3.0‐14.2). The cumulative risk varied between and within regions, with the highest risks observed in Nairobi‐Kenya, Mauritius and the Seychelles. There were similar or more rapidly increasing incidence rates in women aged 50+ compared to women <50 years in all registries except The Gambia. Birth cohort analyses revealed increases in the incidence rates in successive generations of women aged 45 and over in Harare‐Zimbabwe and Kampala‐Uganda. In conclusion, the incidence of BC is increasing rapidly in many parts of Africa; however, the magnitude of these changes differs. These results highlight the need for urgent actions across the cancer continuum from in‐depth risk factor studies to provision of adequate therapy as well as the necessity of supporting the maintenance of good quality population‐based cancer registration in Africa.
What's new?
Breast cancer is the leading cause of cancer in sub‐Saharan Africa (SSA), and may be on the rise. In this study, the authors examined registries from ten SSA countries, and found that this is indeed the case, especially in older women. Changing risk‐factor profiles may account for these trends. These results indicate an urgent need for strengthening the healthcare systems of SSA, including improved public health programs such as screening programs for breast cancer, in‐depth risk‐factor analysis, etc., as well as planning for adequate therapy for an increasing number of patients.

Malignant renal tumours represent 5% of childhood cancers and include types with likely different aetiology: Wilms tumour (WT), rhabdoid renal tumour, kidney sarcomas and renal carcinomas. WT is the ...most common renal tumour in children, previously shown to vary internationally and with ethnicity. Using the comprehensive database of the International Incidence of Childhood Cancer study (IICC), we analysed global variations and time trends in incidence of renal tumour types in children (age 0‐14 years) and adolescents (age 15‐19 years). The results were presented by 14 world regions, and five ethnic groups in the US. We included 15 320 renal tumours in children and 800 in adolescents reported to the 163 contributing registries during 2001‐2010. In children, age‐standardised incidence rate (ASR) of renal tumours was 8.3 per million (95% confidence interval, CI = 8.1, 8.4); it was the highest in North America and Europe (9‐10 per million) and the lowest in most Asian regions (4‐5 per million). In the US, Blacks had the highest ASR (10.9 per million, 95% CI = 10.2, 11.6) and Asian and Pacific Islanders the lowest (4.4 per million, 95% CI = 3.6, 5.1). In adolescents, age‐specific incidence rate of renal tumours was 1.4 per million (95% CI = 1.3, 1.5). WT accounted for over 90% of all renal tumours in each age from 1 to 7 years and the proportion of renal carcinomas increased gradually with age. From 1996 to 2010, incidence remained mostly stable for WT (average annual percent change, AAPC = 0.1) and increased for renal carcinomas in children (AAPC = 3.7) and adolescents (AAPC = 3.2). Our findings warrant further monitoring.
What's new?
Based on more than 16,000 incident cases in the period 2001‐2010, this study offers the most complete overview to date of the worldwide patterns of renal tumours in children and adolescents. Using the comprehensive International Incidence of Childhood Cancer database, the authors also describe the distribution of rare entities such as rhabdoid renal tumour or kidney sarcomas. The results indicate the stable incidence of Wilms tumour, the most common renal tumour in children, consistently with a likely genetic origin. The rising incidence of renal carcinomas with age and over time is likely caused by environmental risk factors, warranting further monitoring.

The National Cancer Center (NCC) of China regularly reports the nationwide statistics on cancer incidence and mortality in China. The International Agency for Research on Cancer (IARC) calculates and ...publishes the cancer burden of countries around the world every two years. To ensure consistency between the actual surveillance data in China and the data published by IARC, NCC has received approval from the National Health Commission and IARC to simultaneously release the cancer burden data for China in GLOBOCAN 2022.
There were a total of 700 registries reporting high-quality data on cancer incidence and mortality across China in 2018, of which 106 registries with continuous monitoring from 2010 to 2018 were used to establish an age-period-cohort model to simulate the trend of cancer incidence and mortality and to estimate the incidence and mortality in China in 2022. In addition, we analyzed the temporal trends of age-standardized cancer incidence and mortality from 2000 to 2018 using data from 22 continuous cancer registries.
It was estimated about 4,824,700 new cancer cases and 2,574,200 new cancer deaths occurred in China in 2022. Cancers of the lung, colon-rectum, thyroid, liver and stomach were the top five cancer types, accounting for 57.42% of new cancer cases. Cancers of the lung, liver, stomach, colon-rectum and esophagus were the five leading causes of cancer deaths, accounting for 67.50% of total cancer deaths. The crude rate and age-standardized incidence rate (ASIR) were 341.75 per 100,000 and 201.61 per 100,000, respectively. The crude mortality rate was 182.34 per 100,000 and the age-standardized mortality rate (ASMR) was 96.47 per 100,000. The ASIR of all cancers combined increased by approximately 1.4% per year during 2000–2018, while the ASMR decreased by approximately 1.3% per year. We observed decreasing trends in ASIR and ASMR for cancers of the esophagus, stomach, and liver, whereas the ASIR increased significantly for cancers of the thyroid, prostate, and cervix.
Cancer remains a major public health concern in China, with a cancer profile that reflects the coexistence of developed and developing regions. Sustained implementation of prevention and control measures has resulted in significant reductions in the incidence and mortality rates of certain historically high incidence cancers, such as esophageal, stomach and liver cancers. Adherence to the guidelines of the Healthy China Action Plan and the Cancer Prevention and Control Action Plan, along with continued efforts in comprehensive risk factor control, cancer screening, early diagnosis and treatment, and standardization of diagnostic and therapeutic protocols, are key strategies to effectively mitigate the increasing cancer burden by 2030.

Guideline recommendations for the treatment of breast cancer with low hormone receptor (HR) expression (1%-9%) are ambiguous and several studies showed more similarities with HR-negative tumors than ...with HR strongly positive tumors (≥10%). We used a population-based 15-year cohort to compare patient characteristics and outcome of HR low positive tumors with HR-negative and HR strongly positive tumors, respectively.
A total of 38 560 women diagnosed with early invasive breast cancer between 2004 and 2018 within the scope of the Munich Cancer Registry with 4.9 million inhabitants were included. Descriptive analyses of prognostic factors, treatment, and outcome analyses using the Kaplan–Meier method; cumulative incidence in consideration of competing risks; and multivariate analyses (Cox regression and Fine–Gray model) were conducted. Endpoints were time to local recurrence (TTLR), time to lymph node recurrence (TTLNR), time to metastasis (TTM), overall survival (OS), and relative survival (RS).
A total of 861 patients (2%) had HR low positive, 4862 (13%) HR-negative, and 32 837 (85%) HR strongly positive tumors. Within the HER2-negative cohort (n = 33 366), survival of HR low positive tumors was significantly worse than that of HR strongly positive tumors OS hazard ratio 0.66 (95% confidence interval 0.55-0.78), whereas between HR low positive and HR-negative tumors no significant survival difference could be detected OS hazard ratio 0.93 (95% confidence interval 0.78-1.11). TTLR, TTLNR, and TTM showed similar results. By contrast, within the HER2-positive cohort (n = 5194), no statistically significant differences between the three HR groups could be detected in multivariate analyses.
Current definitions for HR positivity and its clinical relevance should be reconsidered. Patients with HR low positive/HER2-negative tumors could be regarded and treated similar to patients with triple-negative tumors.

Background: The Hospital-based Cancer Registry (HBCR) part of the National Cancer Registry Programme provides the number of cancer cases attending the hospital in various disciplines and the exact ...type of cases classified, diagnosed and treated. This study was done to assess the socio-demographic, clinical profile, and trend of malignancy cases in the tertiary care centres of Mangalore. Methodology: This Record-based retrospective study was conducted in tertiary care hospitals affiliated with Kasturba Medical College, Mangalore and all the cases of malignancies admitted during the study period were included. The data were collected using a proforma and analyzed using SPSS version 25.0. The results were expressed as proportions using appropriate tables and graphs. Results: A total of 600 cancer cases were identified, with females comprising nearly half 48.8%(n=293) and among them the highest number of cases, 28% (n=82) were found in the age group 60 and above. Overall, cancer cases appear to be more prevalent in older age groups for both genders. Among males, the most common cancers were Oral cavity cancers 34.2%(n=105), followed by Gastrointestinal (GI) tract cancers,16.3%(n=50). In females the most common cancers were found to be of the breast followed by uterine cancer then by oral cavity Conclusion: The prevalence of cancer in both genders were found to be almost the same. The highest number of cases were reported from Karnataka followed by Kerala. The highest prevalence was found in higher extremes of age above 60 years.
