Breast cancer management during the COVID-19 pandemic: Report from a General Hospital Based Cancer Registry from 2019 to 2022

Purpose: This study aimed to describe breast cancer management during the COVID-19 pandemic. Methods: This research is a retrospective descriptive study using secondary data from medical records. The study included 70 patients with breast cancer at Dr. M. Djamil General Hospital from March 2019 to December 2022, who met the inclusion and exclusion criteria. The data analysis used is univariate analysis and presented in the form of a frequency distribution table so that a descriptive picture of each variable studied is obtained. Results: This study included 70 patients with mean age of 40.91 years. During the pandemic, 60.0% of the patients visited the surgical polyclinic. Half of the breast cancer patients had a secondary diagnosis such as pleural effusion (28.6%). The majority of the subjects were at stage IIIC (32.9%). More than half (51.4%) of the patients underwent a modified radical mastectomy. The most common pathological anatomy diagnosis was invasive carcinoma mammae NST (47.1%). An Immunohistochemistry examination was conducted on 24 (34.3%) subjects. Less than half of the patients received chemotherapy. The majority of the patients underwent surgery and chemotherapy 1 month after diagnosis. Mortality is seen in 8.7% of breast cancer patients. Conclusion: During the COVID-19 pandemic, the majority of breast cancer patients undergo anatomical pathology and immunohistochemistry examination through the surgical polyclinic, breast cancer patients who come to the emergency department are usually admitted with breathing problems due to pleural effusion, and surgery and chemotherapy are performed within 1 month.

Development of a Prognostic Model for Stage IV Colorectal Cancer Using Metastatic Patterns.

Metastatic patterns are the most convenient and common prediction models for the prognosis of patients with stage IV colorectal cancer. However, current prediction models do not include the severity of metastases in organs and exclude certain types of metastatic patterns. The aim of this study was to develop a prediction model that included several metastatic organs as well as the severity of liver and lung metastases, based on the Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma: the 3rd English Edition. We performed a state-wide cohort study and developed a prediction model using Cox proportional hazard regression analysis, utilizing data on patients with stage IV colorectal cancer in hospital-based cancer registries of all nine designated cancer hospitals across Fukushima Prefecture, Japan. The study included 1,230 patients with stage IV colorectal cancer. The prediction score consisted of the severity of liver and lung metastases, peritoneal dissemination, non-regional lymph node metastases, and other organ metastases (scale: 0-9 on a 10-point scale; divided into a 2-point scale, grade: I-V). The study found that the model had good discrimination properties, with a Harrell's concordance index of 0.64 (95% confidence interval: 0.62-0.66), and the grade was an independent prognostic factor [hazard ratio (HR)=1.83; 95% confidence interval=1.68-2.00; p<0.001]. We created a practical prediction model for stage IV colorectal cancer that can be applied at the time of diagnosis, using only metastatic patterns. Further external validation studies are required to ensure the accuracy of this model.

Clinical Features and Prognosis of Malignant Cutaneous Adnexal Tumors: A Retrospective Study Using a Japanese Database.

Malignant cutaneous adnexal tumors (MCATs) are rare. Previous population-based studies to determine the clinical features and prognosis of MCATs mainly included Caucasian patients, and the characteristics of Asian patients with MCATs have not yet been investigated. We aimed to investigate the characteristics of Asian patients with MCAT using a Japanese database. This retrospective study of patients with MCATs from 2012 to 2015 was conducted using a database linked to the Hospital-Based Cancer Registry and Diagnosis Procedure Combination data. Patient characteristics and survival data were analyzed using the Kaplan-Meier method and Cox regression analysis. A total of 1930 patients were included. The median age at diagnosis was 76 years (range, 14-107 years), and 46.3% of the patients were male. The most common histological finding was sebaceous adenocarcinoma (41.6%), followed by porocarcinoma (21.7%). The 5-year overall survival rate was 72.3% (95% confidence interval [CI]: 70.2%-74.3%). A favorable factor for overall survival was female sex (hazard ratio [HR]: 0.78, 95% CI: 0.64-0.96), while unfavorable factors were age > 80 years (HR: 4.40, 95% CI: 3.56-5.46), Stage ≥II (Stage II, HR: 1.34, 95% CI: 1.05-1.71; Stage III, HR: 3.12, 95% CI: 2.16-4.50; Stage IV, HR: 7.31, 95% CI: 4.92-10.87), and histologic findings of spiradenocarcinoma (HR: 4.66, 95% CI: 1.64-13.24). Tumor characteristics and prognosis of MCATs differed among subtypes. Moreover, we found differences between our data and those from other databases. Further investigations are warranted to explore these differences.

Global Distribution of Colorectal Cancer Staging at Diagnosis: An Evidence Synthesis.

Stage at diagnosis is a key prognostic factor for colorectal cancer (CRC) survival. We aimed to assess the global distribution of CRC staging at diagnosis using population-based or hospital-based registry data. We systematically searched in MEDLINE and Embase from their inception until 6 December 2023. Grey literature was searched through published cancer reports. Studies from population-based or hospital-based cancer registries reporting the stage distribution of diagnosed CRC were included. We extracted stage-specific proportions among patients with CRC based on TNM, SEER, or Dukes staging systems. Subgroup analyses by sex, age, tumor site, calendar period, and status of population-based screening were performed. Correlations between the Human Development Index (HDI), Socio-Demographic Index (SDI), and the distant metastatic CRC proportion were also evaluated. 84 eligible studies/reports from 46 countries were analyzed, covering 3.8 million patients. Among 36 countries included in the main analysis, the most recent distant metastatic CRC proportions varied from 16.2% in Puerto Rico to 28.2% in Oman and Latvia, with a median (interquartile range) of 23.7% (21.8%-26.3%). Higher metastatic proportions were observed in younger patients, those with colon cancer, and those without screening implementation, with no apparent difference between males and females. Over time, some countries/regions, such as Southern Portugal (36.5% in 2000 to 22.2% in 2016), showed declining proportions of metastatic CRC, while others remained stable (e.g., Austria, Belgium) or increased (e.g., United States, Slovenia, Spain). Higher HDI and SDI were correlated with lower proportions of distant metastatic CRC (HDI: ρ=-0.48; SDI: ρ=-0.26). Global disparities in CRC staging exist, indicating a need for targeted interventions to enhance early detection and management, especially in high-metastasis areas.

Trends of prostate cancer treatment in Ehime Prefecture, Japan: analysis of a hospital-based cancer registry

BackgroundWe previously conducted a retrospective Japanese cohort study of patients who underwent radical prostatectomy (RP) between January 2010 and December 2020 in Ehime Prefecture. This study revealed an increase in the number of RP, but other treatment trends remained unclear. In the current study, we examined prostate cancer treatment in Ehime Prefecture using the hospital-based cancer registry of all designated cancer care hospitals and community cancer care hospitals belonging to the Council of Ehime Cancer Care Hospitals.MethodsTrends of prostate cancer were compared by year according to stage and treatment using data from the hospital-based cancer registry between 2011 and 2020.ResultsThe number of patients with stage 1 disease increased over time, but the proportion of patients with stage 1 disease among all patients decreased from 65.2% in 2012 to 56.9% in 2020. The number of patients with stage 2 disease also increased, but the proportion of such patients among all patients remained constant. Meanwhile, the proportions of patients with stage 3 or 4 disease increased significantly over time, while that of patients undergoing RP increased from 29.2% in 2011 to 45.7% in 2020 (P < 0.001). The proportion of patients receiving radiotherapy (RT) decreased from 25.8% in 2011 to 17.2% in 2020. The use of hormone therapy (HT) remained unchanged, and the proportion of patients undergoing observation fell from 11.0% in 2011 to 7.0% in 2020. A higher proportion of patients with stage 3 cancer received HT, and RT was more frequently used in stage 3 cancer than in stage 1–2 cancer. The use of HT increased with age.ConclusionsThe data highlighted differences in prostate cancer stages and treatment over time. This information could be shared with both urologists and radiologists to improve treatment.

Socioeconomic Factors' Impact on Survivorship in Patients with Cervical Cancer: A Study from the Tertiary Cancer Center in Muzaffarpur, North Bihar, India

ObjectiveTo ascertain the survivorship among cervical cancer patients and the factors responsible for early death. In India, cervical cancer ranks second among cancer-related deaths among women. Estimating the survivability rate of patients with cervical cancer who come to our tertiary cancer care center was imperative, as was figuring out.What was causing the greater death rate.MethodThe present study is a retrospective audit of cervical cancer registered at our hospital-based cancer registry from 2021 till date.ResultThe three-year survival rate among women with late-stage cervical cancer was 45%, while 100% of women with early-stage care were alive at the end of three years. The survival rate was also poor among women belonging to middle and low socioeconomic status and illiterate women.ConclusionAmong women who have cervical cancer, those with early-stage cancer, who are literate and those who belong to above middle socioeconomic status have higher survivorship than their counterparts.

Improving childhood cancer care in South Africa using the Paediatric Oncology Facility Integrated Local Evaluation (PrOFILE) tool

Aim Using the St. Jude Paediatric Oncology Facility Integrated Local Evaluation (PrOFILE) tool, the South African Association of Paediatric Haematology Oncology (SAAPHO) collaborated with St Jude Children’s Research Hospital to evaluate the delivery of health services and provide evidence-based assessments to inform and prioritise action plans to improve childhood cancer care. Methods PrOFILE was used to assess paediatric oncology care in thirteen public-sector hospitals comprehensively. Following that, representatives from each of the thirteen public-sector hospitals and from SAAPHO, the National Department of Health, the World Health Organization, St. Jude Global, and Childhood Cancer Foundation South Africa participated in a national stakeholder prioritisation workshop. Participants were assigned one of the PrOFILE components (Context, Workforce, Diagnostics, Multidisciplinary Team, Therapy, or Patients and Outcomes), forming six working groups to assess, map, and evaluate childhood cancer topics. Using a modified implementation mapping approach and through participation in structured co-designed activities, each group designed multi-level health interventions: prioritising initiatives identified by the SAAPHO, setting goals for each priority, co-designing project-specific logic models, reviewing potential barriers to implementation, and developing a post-workshop agenda. Results Individual hospital reports and a national aggregate report were compiled to discuss opportunities and priorities. The goal of the workshop was to utilise evidence-based assessments to achieve, a) objective assessment data to inform prioritisation exercises conducted by stakeholders, and b) priorities and action plans to inform childhood cancer control activities and demonstrate national organisation, human resources capabilities, and technical support to improve childhood cancer care. Through structured discussion and voting, six priority areas were identified and assigned to working groups: redrafting the organisation’s constitution, standardising multidisciplinary reporting, developing protocols and treatment guidelines, establishing fever-management guidelines, strengthening chemotherapy safety practices, and enhancing hospital-based cancer registries. Conclusions An implementation map enabled stakeholders to develop actionable plans, the success of which is demonstrated by the active implementation of the identified priorities by the focused working groups. This could serve as a model for countries with identified priorities but need more means to implement them. Based on mapping and outputs from the PrOFILE workshop, the NDoH will facilitate the creation of a childhood cancer committee to sustain progress on the key themes and priorities identified through the PrOFILE mapping process.

Hospital-based registries of women with breast cancer from the oncology network of Espírito Santo, Brazil

Objective: To describe the cases of women with breast cancer (BC) and identify the epidemiological profile of the cases reported in the Hospital-based Cancer Registries (HCR) of the Oncological Care Network of Espírito Santo (OCN/ES). Methods: This is a hospital-based descriptive observational study, based on secondary data retrieved via the HCR Tumor Registration Form of the eight hospitals that comprising the OCN/ES, between 2000-2020. Results: There were 16,844 case records of women with breast cancer in this historical series. The median age of the women was 52 years. The age group with the highest number of cases (54.0%) was 41-60 years, 57.42% were brown, 51.70% married, and 30.80% had incomplete elementary school, residents of the Metropolitan region of the state (81.70%). Most cases were analytical (75.42%), referred from SUS (59.70%), had no occurrence of more than one primary tumor (94.21%), the most common histological type was infiltrating duct carcinoma (76.03%), and stage II (6.75%), with multimodal treatments (60.09%). Conclusion: The findings point to an increasing trend in the occurrence of breast cancer over the years in OCN/ES, occurring mainly in older, brown women and women with low education, in stage II of the disease.

Evaluating implementation of a hospital-based cancer registry to improve childhood cancer care in low- and middle-income countries.

Cancer is a leading cause of global childhood mortality, affecting 400,000 children annually. While treatable with modern therapies, children living in low- and middle-income countries (LMICs) have limited access to care and lower survival rates. Hospital-based cancer registries (HBCRs) collect detailed patient information to critically evaluate and evolve care. The St. Jude Global Childhood Cancer Analytics Resource and Epidemiological Surveillance System (SJCARES) is a cloud-based HBCR network facilitating quality data collection of pediatric cancer. Wide variation in the success of implementation has warranted further research into the implementation approach, to create a sustainable and adaptable HBCR in LMICs. Seven of 89 sites using the SJCARES registry were selected, stratified by global region and stage of implementation. Semi-structured interviews were conducted with key groups (clinicians, administrators, data clerks) using an interview guide developed from the Consolidation Framework for Implementation Research (CFIR). Interviews were conducted via a video-telephone software program and transcribed by a transcription service. Transcripts were thematically coded using rapid qualitative analysis. A total of 18 participants (11 clinicians, 4 administrators, 3 data clerks) were interviewed. Several barrier themes were identified, including: difficulty integrating the registry into existing workflow; lack of resources; lack of government or administrative support; and damaged, misplaced, or illegible medical records. Facilitator themes were identified, including: internal support for the registry; clear and extensive training; and dedicated support staff. Interviewed participants identified key barriers and facilitators to the implementation of the SJCARES registry across multiple phases. We plan to use these results to develop targeted implementation strategies including a readiness assessment tool to help guide more successful implementation of the SJCARES registry and other HBCRs in LMICs.

Accuracy Analysis of Topographical and Morphological Code in the RSUP Dr. Sardjito Cancer Registry, Indonesia

In cancer cases, a cancer registry functions as a national cancer control program to analyze cancer severity and risk factors in specific areas, aiming to reduce morbidity and mortality. Accurate coding is essential for producing a high-quality cancer database. This study aims to analyze the accuracy of the cancer registry at RSUP Dr. Sardjito in assigning topography and morphology codes. A mixed-methods approach was employed to evaluate code accuracy and identify factors influencing accuracy and inaccuracy based on the 5M framework. Data were sourced from the Hospital-Based Cancer Registry at RSUP Dr. Sardjito, with a total population of 4500 patients in 2021. A sample of 1000 cancer patients was selected using a simple random sampling technique. Each sample was analyzed as true or false based on verifier notes, revealing that 904 topography codes were accurate (90.40%) and 96 were inaccurate (9.60%). For morphology codes, 913 were accurate (91.30%) and 87 were inaccurate (8.70%). Researchers conducted in-depth interviews with registrars and verifier doctors and observed all cancer registry activities, focusing on topography and morphology codification. Observations and interviews indicated no obstacles in codification activities, but inaccuracies occurred, possibly due to case complexity. In conclusion, the study demonstrates high accuracy in the coding of cancer cases at RSUP Dr. Sardjito. The complexity of cases may contribute to inaccuracies. The study suggests continuous evaluation to enhance coding accuracy, which is crucial for effective cancer control programs.

Trends in Presentation, Management, and Survival of Women With Breast Cancer in a Multiethnic, Middle-Income Asian Setting.

Granular data on breast cancer (BC) are pertinent for surveillance, planning, and monitoring of cancer care delivery. We determined the trends in clinical presentation, management, and survival of women with BC in a multiethnic middle-income Asian setting over 15 years. Data of 7,478 Malaysian women newly diagnosed with invasive BC between 2005 and 2019 from three hospital-based cancer registries were included. Trends in demographic, tumor, and treatment characteristics were compared across period 1 (P1): 2005-2009, period 2 (P2): 2010-2014, and period 3 (P3): 2015-2019. Overall survival and net survival were determined. More women in P3 than P1 were older than 60 years at diagnosis. Only a marginal increase in proportion of women with stage I disease was observed (23.7% v 27.2% in P1 and P3, respectively, P = .004). Nonetheless, patients were increasingly presenting with smaller tumors, fewer axillary node involvement, well-differentiated tumors, and hormone receptor expression in recent times. Proportion of women with human epidermal growth factor receptor 2 (HER2)-overexpressed tumors significantly decreased. Among indicated patients, receipt of anticancer therapies was somewhat similar over the calendar periods, except for neoadjuvant chemotherapy and anti-HER2 therapy, where increases in administration were noted. Significant improvements in survival were observed over the 15 years, particularly for HER2-overexpressed BCs. Although the improvements in BC survival that we have observed validate ongoing cancer control efforts and treatment advances, study findings suggest that more could be done for earlier detection and improved access to effective therapies in our settings.

Implementation research on registering cancer cases in primary health centres of Puducherry through community health workers.

Background & objectives Hospital-based cancer registry does not represent the true burden of cancer in the community. Initiating a Primary Health Centre (PHC)-based cancer registry may better estimate population-level data for cancer cases in an area. This study aimed to set up a system for facilitating a PHC-based cancer registry and to assess the registration status of cancer cases in various PHCs of Puducherry. The facilitating and limiting factors while setting up this registry were also assessed. Methods A quasi-experimental study with an embedded mixed-method design was conducted in 31 PHCs/Community Health Centres (CHCs) from March 2021 to November 2022. The interventions were implemented in all PHCs/CHCs of Puducherry with the involvement of the State Non-Communicable Diseases (NCD) cell. The line list of cancer cases from the Jawaharlal Institute of Postgraduate Medical Education & Research (JIPMER) Hospital-based cancer registry was shared with all PHCs/CHCs. Sensitization sessions for all Community Health Workers (CHWs) were conducted, and feedback on cancer registration status was given to the State NCD cell. Focus group discussion (FGD)/Key informant interview (KII) was undertaken to understand strengths, challenges, and suggestions. The logic model was used to understand the various indicators while setting up this PHC-based cancer registry. Results Over a one-year intervention period, 1270 cancer cases were registered at Puducherry's PHCs/CHCs, 1203 (88%) from the shared list and 67(5%) from other facilities. However, only 53 per cent of the expected living cases were captured in the various PHCs. Major limitations for registration were the COVID-19 pandemic, stigma, inadequate manpower, infrastructure issues, and privacy concerns during screening. Interpretation & conclusions It was feasible to set up a PHC-based cancer registry in all PHCs of Puducherry. However, registration of cancer cases was suboptimal, as population-based screening of cancer cases, as recommended in the National Programme for Prevention & Control of Non-Communicable Diseases (NP-NCD) programme, was weak due to the COVID-19 pandemic. Once this is strengthened, the PHC-based cancer registry will better represent the population.

Epidemiology of Cancers in Vidarbha Over 4-year Period, Tobacco-related Cancer and Control

Objectives: The aim of the study was to describe epidemiology of cancer in Vidarbha, according to findings from National Cancer Registry Programme (NCRP). Material and Methods: The data on cancer have been sourced from Hospital Based Cancer Registries of Rashtrasant Tukdoji Cancer Hospital and Research Centre under NCRP in Vidarbha. The data are covering a period of 4 years (2017–2020). Results: The Hospital-based cancer Registry of Rashtrasant Tukdoji Cancer Hospital and Research Center indicates 11,868 malignant cases registered in the hospital during the period of past years (2017–2020). The top 5 leading sites in males were buccal mucosa, tongue, lung, alveolus and oesophagus. In females, top 5 leading sites are buccal mucosa, tongue, oesophagus, lung and alveolus. The Rashtrasant Tukdoji Cancer Hospital data of cumulative distribution of cancer cases according to age and gender which cancer was found to be more in males than females and increased incidence in younger ages is observed in the study. Conclusion: Epidemiological studies help in assessing cancers and help to assess their risk factors and help in improving and strengthening efforts for cancer prevention and control. Epidemiological studies show that many cancer can be avoidable with primary and secondary preventive measures and also helps in estimating the cancer burden in the near future and helps in planning and evaluating strategies by keeping track of cancer prevalence. Cancer registry plays an important role in such studies.

Childhood cancer presentation and initial outcomes in Ethiopia: Findings from a recently opened pediatric oncology unit.

There were no pediatric oncology centers in southwest Ethiopia prior to 2016. This study aims to describe presenting diagnoses and initial outcomes at Jimma University Medical Center (JUMC), the first pediatric oncology unit (POU) in southwest Ethiopia, provide initial insights into regional pediatric cancer epidemiology, illustrate the rapid growth of pediatric cancer services, and highlight ongoing challenges. We used a retrospective descriptive approach to assess the epidemiologic pattern and initial treatment outcomes of pediatric cancer at JUMC POU from August 2016 through December 2022. During the study period, 749 children were diagnosed with cancer at JUMC. The mean age was 7.2 years (20 days-18 years). Acute lymphoblastic leukemia was the most common diagnosis (16.4%), followed by non-Hodgkin lymphoma (12.4%), Wilms tumor (11.1%), soft tissue sarcoma (8.8%), Hodgkin lymphoma (8.4%), and retinoblastoma (8.3%). Brain tumors accounted for only 2.7% of the diagnoses. Of the 703 patients that were not referred elsewhere, 42% of the patients abandoned treatment, 29% died, 17% completed treatment, and 7% remained on treatment at the time of this assessment. The findings emphasize the growth in the diagnosis and treatment of children with cancer in the southwest region of Ethiopia. The data suggests a different epidemiologic profile of childhood cancer cases diagnosed at the JUMC POU compared to high-income countries and neighbouring countries in Africa. Treatment abandonment remains a barrier to care. Ongoing areas of focus include establishment of a hospital-based cancer registry, reduction of treatment abandonment, improvement of diagnostic capacity, and increased access to advanced supportive care.

Biomarker Testing Disparities in Metastatic Colorectal Cancer

Among patients with metastatic colorectal cancer (mCRC), data are limited on disparate biomarker testing and its association with clinical outcomes on a national scale. To evaluate the socioeconomic and demographic inequities in microsatellite instability (MSI) and KRAS biomarker testing among patients with mCRC and to explore the association of testing with overall survival (OS). This cohort study, conducted between November 2022 and March 2024, included patients who were diagnosed with mCRC between January 1, 2010, and December 31, 2017. The study obtained data from the National Cancer Database, a hospital-based cancer registry in the US. Patients with mCRC and available information on biomarker testing were included. Patients were classified based on whether they completed or did not complete MSI or KRAS tests. Demographic and socioeconomic factors, such as age, race, ethnicity, educational level in area of residence, median household income, insurance type, area of residence, facility type, and facility location were evaluated. The main outcomes were MSI and KRAS testing between the date of diagnosis and the date of first-course therapy. Univariable and multivariable logistic regressions were used to identify the relevant factors in MSI and KRAS testing. The OS outcomes were also evaluated. Among the 41 061 patients included (22 362 males [54.5%]; mean [SD] age, 62.3 [10.1] years; 17.3% identified as Black individuals, 78.0% as White individuals, 4.7% as individuals of other race, with 6.5% Hispanic or 93.5% non-Hispanic ethnicity), 28.8% underwent KRAS testing and 43.7% received MSI testing. A significant proportion of patients had Medicare insurance (43.6%), received treatment at a comprehensive community cancer program (40.5%), and lived in an area with lower educational level (51.3%). Factors associated with a lower likelihood of MSI testing included age of 70 to 79 years (relative risk [RR], 0.70; 95% CI, 0.66-0.74; P < .001), treatment at a community cancer program (RR, 0.74; 95% CI, 0.70-0.79; P < .001), rural residency (RR, 0.80; 95% CI, 0.69-0.92; P < .001), lower educational level in area of residence (RR, 0.84; 95% CI, 0.79-0.89; P < .001), and treatment at East South Central facilities (RR, 0.67; 95% CI, 0.61-0.73; P < .001). Similar patterns were observed for KRAS testing. Survival analysis showed modest OS improvement in patients with MSI testing (hazard ratio, 0.93; 95% CI, 0.91-0.96; P < .001). The median (IQR) follow-up time for the survival analysis was 13.96 (3.71-29.34) months. This cohort study of patients with mCRC found that older age, community-setting treatment, lower educational level in area of residence, and treatment at East South Central facilities were associated with a reduced likelihood of MSI and KRAS testing. Highlighting the sociodemographic-based disparities in biomarker testing can inform the development of strategies that promote equity in cancer care and improve outcomes for underserved populations.

Descriptive epidemiology of prostate cancer in India, 2012-2019: Insights from the National Cancer Registry Programme.

This study describes the epidemiology, clinical extent at diagnosis, and treatment modalities for prostate cancer in India. This study is a secondary analysis of primary prostate cancer data sourced from the National Cancer Registry Programme. Data from population-based cancer registry for the period 2012-2016 were used to estimate the incidence rates, including crude incidence rate (CR), age-adjusted incidence rate (AAR), age-specific rate, and cumulative risk. Trends in the AAR were assessed using join-point regression. Hospital-Based Cancer Registry data from 2012 to 2019 were used to describe the clinical extent of the cancer at diagnosis and the treatment modalities. The incidence of prostate cancers was higher in urban registries such as Delhi, Kamrup Urban, and Mumbai (AAR of 11.8 per 100,000, 10.9 per 100,000, and 9.7 per 100,000, respectively). Prostate cancer incidence showed a rise after the age of 50, with a notable acceleration after age 64. The overall annual percentage change for prostate cancer incidence from 1982 to 2016 was 2.6. Around 43.0% of all prostate cancers were diagnosed at the distant metastatic stage. Surgery and radiotherapy, either as standalone treatments or in combination with other modalities, contributed to the treatment of 78.5% of localized cancer, 74.2% of locoregional cancer, and 57.2% of distant metastatic stage of prostate cancer. There is heterogeneity in the incidence of prostate cancer, as evidenced by urban registries. Additionally, there is a need for downstaging the disease, without risking overdiagnosis.

Magnitude and patterns of cancers in North Malabar region of Kerala, India, from 2010-2019: Update from a retrospective hospital-based cancer registry data

Trends and Patterns of Top Ten Common Cancers in Eastern India from 2014 to 2021: A Retrospective Hospital-based Cancer Registry Data Update.

India is a vast and diverse country with existing variations in the frequency and distribution of cancers across its various parts. In regions lacking population-based cancer registries (PBCRs) in a vast country like India, hospital-based cancer registry (HBCR) data become an important source of information on the trends and patterns of a region. To determine the numerical trends of cases of the top ten cancer sites reporting to HBCR of a tertiary care cancer center in Bihar from 2014 to 2021. The details of all histopathologically confirmed cancer cases registered in the HBCR department of radiation oncology, State Cancer Institute, Indira Gandhi Institute of Medical Sciences, Patna, India between January 2014 and December 2021 were included in this retrospective observational study. All these cases were grouped site-wise and listed in descending order of the total number of cases reported in each group. Cross-tabulation with age and sex distribution was done. The frequency distribution of the top ten leading cancers for every consecutive calendar year was plotted in line diagrams for time trend analysis. Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp.). was used for analysis. Annual percent change (APC) was determined for the number of cases of all ten cancer sites using joinpoint regression analysis (Joinpoint Regression Software, Version 4.0.4-May 2013; Statistical Methodology and Applications Branch, Surveillance Research Program of the US National Cancer Institute; Bethesda, MD, USA). Out of 32,057 total cancer cases registered between Jan 2014 and Dec 2021, 21,848 patients (68.2%) cases constituted the top ten cancers. The top ten cancers among both sexes were cancer gallbladder (n = 4204, 13.1%), head and neck (n = 3395, 10.6%), breast (n = 3392, 10.6%), lung (n = 2069, 6.5%), cervix (n = 2039, 6.4%), hematolymphoid (n = 1930, 6.0%), liver (n = 1572, 4.9%), stomach (n = 1116, 3.5%), ovary (n = 1103, 3.4%), and colon-rectum (n = 1028, 3.2%). Except for cervical and hematolymphoid cancers, the rest all showed a rising trend over consecutive years. Cancer of the gallbladder continues to be among the most common cancers in the region. Focused research in all aspects of this deadly disease is needed. Strengthening of prevention and screening programs for common cancers and upliftment of the existing infrastructure for diagnosis and treatment of cancer in the region are necessitated.

Incidence, mortality, survival, and treatment statistics of cancers in digestive organs-Japanese cancer statistics 2024.

Access to accurate statistical data is paramount in the pursuit of effective cancer control activities, including research, policy development, and clinical care. This paper presents a comprehensive statistical report on the incidence, mortality, survival, and treatment of major digestive organ cancers, including those of the esophagus, stomach, colon, rectum, liver, extrahepatic biliary tract, and pancreas, in Japan. We compiled data from the National Cancer Center's "Cancer Information Services" and government "e-Stat" websites and offered a succinct overview of basic statistics by using tables and graphical presentations. Our findings underscore the critical role of the National Cancer Registry introduced by the Cancer Registry Act of 2016, which mandates hospitals across Japan to report cancer cases. This system ensures more accurate incidence statistics. Mortality data sourced from the National Vital Statistics System and survival rates derived from hospital-based cancer registries offer insights into the outcomes and efficacy of treatment modalities. These data indicate a downward trend in mortality for stomach and liver cancers and stable or declining rates for other cancers except pancreatic cancer, which has the lowest survival rate.

Factors associated with early-stage lung cancer diagnosis (ESLCD) in Brazil, 2013-2019: A multivariable analysis.

e20091 Background: Lung cancer has the highest mortality rate among the leading deadly cancers worldwide. Despite improvements in tobacco cessation and treatment over the years, disparities in access to care, timely diagnosis, and proper treatment remain prevalent. This study aims to identify the factors associated (FA) with Early-Stage Lung Cancer Diagnosis (ESLCD) in Brazil. Methods: This retrospective cohort study includes individuals diagnosed with lung cancer from January 2013 to December 2019, registered in the Brazilian hospital-based Cancer Registry (HBCR). Descriptive and bivariate analysis was performed, and T-tests and Chi-square were used to compare early vs late-stage groups. Multivariable backward stepwise logistic regression identified FA with ESLCD at a 95% confidence interval (CI). Results: The study was conducted with data on 86,558 individuals registered in the HBCR; 56.6% were men, 64 years old on average, and 54.8% were white. We found a high percentage of patients without education information (23.9%), and 70% had completed high school. As for behavioral characteristics, only 20% of the patients had never smoked; the others were current smokers (40%) or former smokers (40%). Almost half of the patients were from the Southeast region of Brazil (44.6%), 27% from the South, 19.9% from the Northeast, 3.9% from the North and 3.9% from the Midwest. The vast majority of the individuals were diagnosed at a late stage (85.6%), while 14.4% were ESLCD. In the bivariate analysis, being less than 65 years old, being female, white, never smoking, having a college degree, and living in the south or southeast regions were associated with ESLCD. In the final multivariable model the Factors Associated with ESLCD were having less than 65 years (OR=1.28 [95% CI: 1.22-1.34]), of the female gender (OR=1.26 [95% CI: 1.22-1.32]), having education greater than a college degree (OR=1.49 [95% CI: 1.38-1.61]), and living on the southeast (OR=1.22 [95% CI: 1.15-1.30]); and in the south region (OR=1.21 [95% CI: 1.18-1.32]); which are the wealthiest regions in the country. Conclusions: The education level was the most decisive factor associated with ESLCD. Geographic location played an important role in ESLCD, indicating issues related to wealth and access to health services. Improving access to lung cancer diagnosis, especially for vulnerable populations, can reduce disparities in the rates of early-stage diagnosis and improve overall survival. [Table: see text]
