UNASSIGNED: In South Korea, the cancer incidence rate has increased by 56.5% from 2001 to 2021. Nevertheless, the 5-year cancer survival rate from 2017 to 2021 increased by 17.9% compared with that from 2001 to 2005. Cancer survival rates tend to decline with lower socioeconomic status, and variations exist in the survival rates among different cancer types. Analyzing socioeconomic patterns in the survival of patients with cancer can help identify high-risk groups and ensure that they benefit from interventions.
UNASSIGNED: The aim of this study was to analyze differences in survival rates among patients diagnosed with six types of cancer-stomach, colorectal, liver, breast, cervical, and lung cancers-based on socioeconomic status using Korean nationwide data.
UNASSIGNED: This study used the Korea Central Cancer Registry database linked to the National Health Information Database to follow up with patients diagnosed with cancer between 2014 and 2018 until December 31, 2021. Kaplan-Meier curves stratified by income status were generated, and log-rank tests were conducted for each cancer type to assess statistical significance. Hazard ratios with 95% CIs for any cause of overall survival were calculated using Cox proportional hazards regression models with the time since diagnosis.
UNASSIGNED: The survival rates for the six different types of cancer were as follows: stomach cancer, 69.6% (96,404/138,462); colorectal cancer, 66.6% (83,406/125,156); liver cancer, 33.7% (23,860/70,712); lung cancer, 30.4% (33,203/109,116); breast cancer, 91.5% (90,730/99,159); and cervical cancer, 78% (12,930/16,580). When comparing the medical aid group to the highest income group, the hazard ratios were 1.72 (95% CI 1.66-1.79) for stomach cancer, 1.60 (95% CI 1.54-1.56) for colorectal cancer, 1.51 (95% CI 1.45-1.56) for liver cancer, 1.56 (95% CI 1.51-1.59) for lung cancer, 2.19 (95% CI 2.01-2.38) for breast cancer, and 1.65 (95% CI 1.46-1.87) for cervical cancer. A higher deprivation index and advanced diagnostic stage were associated with an increased risk of mortality.
UNASSIGNED: Socioeconomic status significantly mediates disparities in cancer survival in several cancer types. This effect is particularly pronounced in less fatal cancers such as breast cancer. Therefore, considering the type of cancer and socioeconomic factors, social and medical interventions such as early cancer detection and appropriate treatment are necessary for vulnerable populations.

BACKGROUND: Neuroendocrine neoplasms (NENs) are increasing in incidence globally. Previous analysis of the UK cancer database (National Cancer Registration and Analysis Service (NCRAS)) showed a notable female survival advantage in most tumour sites. This study aims to compare NCRAS to the Surveillance, Epidemiology, and End Results Program (SEER) to validate these results using the same statistical methods.
METHODS: A total of 14,834 and 108,399 patients with NENs were extracted from NCRAS and SEER, respectively. Sixty-months survival for both males and females for each anatomical site of NENs were calculated using restricted mean survival time (RMST) and Kaplan-Meier Survival estimates. The sixty-month RMST female survival advantage (FSA) was calculated.
RESULTS: FSA was similar in NCRAS and SEER. The highest FSA occurred in lung and stomach NENs.
CONCLUSIONS: The data from SEER confirm the findings published by NCRAS. Female survival advantage remains unexplained.

BACKGROUND: Cancer patients\' quality of life (QoL) significantly influences treatment response and mortality rates. Understanding QoL domains among patients with cancer and what affects it can help create interventions that improve QoL and ease patients\' experience. This study measures the OoL among patients with cancer and influencing factors.
METHODS: A prospective cross-sectional questionnaire-based study included cancer patients aged >18 currently receiving treatment. The questionnaire collected social and economic data, followed by the validated Arabic version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30). Means and standard deviations for described numeric variables and frequencies and percentages described categorical variables. Analysis of variance, F-tests, and P-values were reported.
RESULTS: Among 182 cancer patients, 60% were female. Younger patients exhibited higher QoL in physical and role functioning (P = .016 and .03) and experienced more significant financial impact (P = .0144). Females reported more adverse effects from cancer symptoms, including fatigue, nausea, vomiting, and pain (36.7% vs 25.5%, P = .005; 20.6% vs 11.5%, P = .0186; 34.7% vs 25.1%, P = .0281). Single patients had superior QoL in physical functioning compared to others (P = .0127). Patients traveling long distances were more likely to face adverse financial consequences (P = .007). Asthmatic patients exhibited lower QoL in physical, role, and cognitive functioning (72.3 vs 37.8, P = .0147; 76.4 vs 22.2, P = .0024; 84.7 vs 44.4, P = .0038) and reported increased dyspnea and appetite loss (16 vs 55.6 and 26.1 vs 66.7, both P < .05).
CONCLUSIONS: Factors influencing QoL in Saudi cancer patients include age, marital status, gender, hospital distance, and chronic conditions. Thus emphasizing the necessity for personalized care strategies to enhance outcomes and alleviate the overall burden of cancer care.

OBJECTIVE: Studies on cancer incidence and mortality among people with opioid use-related disorders are lacking. We aimed to measure cancer-specific incidence, mortality and survival among people diagnosed with opioid use-related disorders in Norway during 2010-18.
METHODS: This was a cohort study conducted in Norway during 2010-18.
METHODS: Individuals (n = 20 710) diagnosed with opioid use-related disorders.
METHODS: We conducted a cohort study utilizing a data-linkage of national health and population registers. Information on opioid use-related disorders was extracted from specialized healthcare, malignancies from the Cancer Registry of Norway and deaths from Cause of Death Registry. Cancer incidence and mortality were compared with the general population by calculating sex-specific age-standardized incidence (SIR) and mortality (SMR) ratios. One-year survival rates were computed.
RESULTS: Compared with the general population, people with opioid use-related disorders were at an increased risk of developing cancer overall [SIR = 1.2, 95% confidence interval (CI) = 1.1-1.3] with a higher than twofold cancer mortality rate (SMR = 2.3, 95% CI = 2.0-2.7). Excess risk was observed for liver (12.6, 95% CI = 9.1-17.0), larynx (4.7, 95% CI = 1.7-10.2), lung (3.5, 95% CI = 2.8-4.3) and pancreas cancer (2.6, 95% CI = 1.6-4.0), whereas reduced risk was found for melanoma (0.5, 95% CI = 0.3-0.9), breast (0.6, 95% CI = 0.4-0.9) and prostate cancers (0.3, 95% CI = 0.1-0.4). Site-specific SMRs were significantly elevated for liver (12.3, 95% CI = 8.5-17.2), lung (3.9, 95% CI = 3.0-5.0), pancreas (3.0, 95% CI = 1.7-4.8) and colon cancers (1.9, 95% CI = 1.1-3.1). The average 1-year survival rate after a cancer diagnosis was low in liver, pancreas and colon cancer, ranging from 10 to 15% less than that of the general population.
CONCLUSIONS: In Norway, cancer incidence and cancer-related mortality appear to be elevated among individuals with opioid use-related disorders.

OBJECTIVE: Cancer patients are among the most vulnerable populations during and after a disaster. We evaluated the impact of treatment interruption on the survival of women with gynecologic cancer in Puerto Rico following Hurricanes Irma and María.
METHODS: A retrospective cohort study among a clinic-based sample of women with gynecological cancer diagnosed between January 2016 and September 2017 (n = 112) was done. Women were followed from their diagnosis until December 2019, to assess vital status. Kaplan-Meier survival curves and Cox proportional hazards models were performed.
RESULTS: Mean age was 56 (± 12.3) years; corpus uteri (58.9%) was the most common gynecologic cancer. Predominant treatments were surgery (91.1%) and chemotherapy (44.6%). Overall, 75.9% were receiving treatment before the hurricanes, 16.1% experienced treatment interruptions, and 8.9% died during the follow-up period. Factors associated with treatment interruption in bivariate analysis included younger age (≤55 years), having regional/distant disease, and receiving > 1 cancer treatment (P < 0.05). Crude analysis revealed an increased risk of death among women with treatment interruption (HR: 3.88, 95% CI: 1.09-13.77), persisting after adjusting for age and cancer stage (HR: 2.49, 95% CI: 0.69-9.01).
CONCLUSIONS: Findings underscore the detrimental impact of treatment interruption on cancer survival in the aftermath of hurricanes, emphasizing the need for emergency response plans for this vulnerable population.

Background Osteosarcoma (OSC) is the most common primary bone tumor and is often managed surgically. Few prior investigations have assessed differences in OSC survival by specific surgical techniques at a national registry level. We sought to compare survival based on surgical subtypes for OSC patients in the Surveillance, Epidemiology, and End Results (SEER) database. Methodology We searched the SEER database for malignant OSCs diagnosed between 2000 and 2019 which were surgically managed. Separate survival comparisons were made for one and five years for wide excision (local tumor destruction or resection versus partial resection) and radical excision (radical resection with limb-sparing versus limb amputation with or without girdle resection). Results A total of 4,303 patients were included, of whom 3,587 were surgically managed. There were no survival differences between local destruction and partial resection (hazard ratio = 0.826, p = 0.303). However, younger age, lower staging, and management without radiation were associated with improved survival. The radical excision comparison showed limb amputation was associated with worse survival than limb-sparing surgery (hazard ratio = 1.531, p < 0.001). Younger age, female sex, lower stage, receipt of chemotherapy, and neoadjuvant plus adjuvant chemotherapy were associated with improved survival while Black and American Indian or Alaska Native were associated with worse survival. Conclusions Our findings show that patients managed with limb-sparing radical resection survived significantly compared to limb amputation. There were no differences in survival for wide excision surgeries. The use of a combination of neoadjuvant and adjuvant chemotherapy also yields improved survival. OSC survival may be optimized with limb-sparing surgery with a combination of neoadjuvant and adjuvant chemotherapy.

Background: The outcomes of patients with colorectal cancer greatly depend on the quality of their surgical care. However, relying solely on a single quality indicator does not adequately capture the multifaceted nature of modern perioperative care. A new tool-\"Textbook Outcome\" (TO)-has been suggested to provide a comprehensive evaluation of surgical quality. This study aims to examine how TO affects the long-term outcomes of colorectal cancer patients who are scheduled for surgery. Methods: The data of all patients undergoing elective colorectal cancer resection with primary anastomosis at two major cancer treatment centers in Lithuania-Vilnius University Hospital Santaros Klinikos and National Cancer Institute-between 2014 and 2018 were entered into the prospectively maintained database. The study defined TO as a composite quality indicator that incorporated seven parameters: R0 resection, retrieval of ≥12 lymph nodes, absence of postoperative complications during the intrahospital period, hospital stay duration of fewer than 14 days, no readmission within 90 days after surgery, no reinterventions within 30 days after surgery, and no 30-day mortality. Long-term outcomes between patients who achieved TO and those who did not were compared. Factors associated with failure to achieve TO were identified. Results: Of the 1524 patients included in the study, TO was achieved by 795 (52.2%). Patients with a higher ASA score (III-IV) were identified to have higher odds of failure to achieve TO (OR 1.497, 95% CI 1.203-1.863), while those who underwent minimally invasive surgery had lower odds for similar failure (OR 0.570, 95% CI 0.460-0.706). TO resulted in improved 5-year overall-(80.2% vs. 65.5%, p = 0.001) and disease-free survival (76.6% vs. 62.6%; p = 0.001) rates. Conclusions: Elective colorectal resections result in successful TO for 52.5% of patients. The likelihood of failure to achieve TO is increased in patients with a high ASA score, while minimally invasive surgery is associated with higher TO rates. Patients who fail to achieve successful surgical outcomes experience reduced long-term outcomes.

BACKGROUND: Cancer diagnosis influences the choices that patients make regarding current and future labor market activity. These choices have implications for governments based on resulting changes in taxes paid and benefits received. In this analysis we explore how human growth receptor 2 (HER2)-positive residual invasive breast cancer and different treatments influence government accounts excluding health costs.
METHODS: HER2-positive early breast cancer (eBC) health states from a published disease model were used to establish likelihood of working and wage impact at different stages of disease. The indirect productivity losses for an average woman aged 49 years were translated into fiscal consequences to government by applying an established government perspective-modeling framework. The fiscal projections (discounted) include gross tax revenue by disease stage, government transfer costs related to time off work and early retirement ,and net fiscal balance (e.g., gross taxes-transfers) in three countries Canada, Portugal, and Brazil.
RESULTS: The net fiscal balance in Canada for a healthy woman was C$109,551 compared with a HER2-positive eBC woman treated with trastuzumab emtansine (C$69,767) or trastuzumab (C$62,971). A similar pattern was observed in the three countries but reflecting the overall tax burden in each country, labor force activity, and available public benefits. Age at diagnosis was an important determinant of the likely net fiscal balance, as this influences the remaining working years.
CONCLUSIONS: Women diagnosed with HER2-positive eBC were estimated to pay less lifetime gross taxes and receive more in sickness benefits compared with healthy women. Treatments that improve outcomes are likely to offer fiscal gains for government from improved work force participation.

OBJECTIVE: Cancer is a leading cause of death among people living with intellectual or developmental disabilities (IDD). There is little empirical evidence documenting survival or comparing outcomes to those without IDD. This study investigated the association between IDD and cancer survival among adults with breast (female), colorectal, or lung cancer.
METHODS: A population-based retrospective cohort study was conducted in Ontario, Canada, with routinely collected data. Patients with breast, colorectal, or lung cancer were included (2007‒2019). IDD status before cancer was determined using an established administrative data algorithm. The outcomes of interest included death from any cause and death from cancer. Cox proportional hazards models and competing events analyses using multivariable cause-specific hazards regression were completed. Analyses were stratified by cancer type. Interactions with age, sex, and stage at diagnosis, as well as sensitivity analyses, were completed.
RESULTS: The final cohorts included 123,695 breast, 98,809 colorectal, and 116,232 lung cancer patients. Individuals with IDD experienced significantly worse survival than those without IDD. The adjusted hazard ratios of all-cause death were 2.74 (95% CI 2.41‒3.12), 2.42 (95% CI 2.18‒2.68), and 1.49 (95% CI 1.34‒1.66) times higher for breast, colorectal, and lung cancer patients with IDD relative to those without. These findings were consistent for cancer-specific deaths. With few exceptions, worse survival for people with IDD persisted regardless of stage at diagnosis.
CONCLUSIONS: People with IDD experienced worse cancer survival than those without IDD. Identifying and intervening on the factors and structures responsible for survival disparities is imperative.
RéSUMé: OBJECTIFS: Le cancer est l’une des principales causes de mortalité chez les personnes vivant avec des déficiences intellectuelles ou des troubles du développement (DI/TD). Il y a peu de preuves empiriques décrivant la survie de ces personnes lorsqu’elles sont atteintes d’un cancer ou comparant leurs résultats à ceux des personnes sans DI/TD. Notre étude porte sur l’association entre les DI/TD et la survie au cancer chez les adultes atteints de cancer du sein (femmes), du colorectum ou du poumon. MéTHODE: Une étude de cohorte rétrospective populationnelle a été menée en Ontario, au Canada, à l’aide de données recueillies systématiquement. Nous avons inclus les patientes et les patients atteints de cancer du sein, du colorectum ou du poumon (2007‒2019). Nous avons identifié la présence des DI/TD avant le cancer à l’aide d’un algorithme de traitement de données administratives reconnu. Les résultats d’intérêt étaient les décès de toutes causes et les décès dus au cancer. Nous avons appliqué des modèles des risques proportionnels de Cox et des analyses des événements concurrents en utilisant la régression multivariée des risques par cause. Nos analyses ont été stratifiées selon le type de cancer. Nous avons tenu compte des interactions avec l’âge, le sexe et le stade au diagnostic et effectué des analyses de sensibilité. RéSULTATS: Les cohortes finales ont inclus 123 695 personnes atteintes de cancer du sein, 98 809 atteintes de cancer colorectal et 116 232 atteintes de cancer du poumon. La survie des sujets ayant des DI/TD a été significativement moins bonne que celle des sujets sans DI/TD. Les rapports de risques instantanés ajustés pour les décès de toutes causes étaient 2,74 fois (IC de 95 % 2,41‒3,12), 2,42 fois (IC de 95 % 2,18‒2,68) et 1,49 fois (IC de 95 % 1,34‒1,66) plus élevés chez les personnes atteintes de cancer du sein, du colorectum et du poumon et ayant des DI/TD que chez les personnes sans DI/TD. Ces constatations ressortent pour tous les décès attribuables à des cancers particuliers. Avec peu d’exceptions, la survie moins bonne pour les personnes ayant des DI/TD persistait quel que soit le stade au moment du diagnostic. CONCLUSION: La survie au cancer était moins bonne chez les personnes ayant des DI/TD que chez celles n’ayant pas de DI/TD. Il est impératif d’identifier les facteurs et les structures responsables de ces disparités dans la survie et d’intervenir en conséquence.

Purpose: To assess the mental health conditions, as indicated by mental health service contact in adolescents and young adults (AYAs) diagnosed with cancer in New South Wales (NSW) and associations with cancer mortality. Methods: In 3998 NSW AYAs diagnosed with cancer in 2005-2017, mental health service contacts were obtained from hospital inpatient records and specified medical and pharmaceutical insurance claims. Odds of postcancer mental health contact were assessed by precancer mental contacts using logistic regression adjusted for sociodemographic and cancer characteristics. The risk of cancer-specific mortality related to postcancer mental health contacts was estimated using competing risk regression. Results: The prevalence of mental health service contacts in the 5 years postcancer diagnosis was 27.0%, higher than the corresponding precancer prevalence of 21.4%. The most common mental health conditions were depression and anxiety. The odds of having a mental health contact postcancer diagnosis were higher in patients with a precancer mental health service contact (adjusted odds ratio 5.69, confidence intervals [95% CIs]: 4.90-6.75). The 5-year cancer-specific survival was 87.9% (95% CI: 85.8-89.8) for patients with a mental health service contact postcancer, which was lower than the 93.9% (95% CI: 93.0-94.7) for patients without this contact. The subhazard ratio (SHR) for cancer mortality in patients having mental health service contact postcancer diagnosis was 1.67 (95% CI: 1.29-2.15), adjusted for sociodemographic characteristics, cancer stage, and precancer mental health status. Conclusion: The prevalence of mental health service contact increased after a cancer diagnosis. Mental health care should be a continued priority for AYA cancer patients, particularly for high-risk groups.
