Travel patterns of patients seeking cancer care during the COVID-19 pandemic: Multi-centre cohort study in Osaka, Japan.

Background: In Japan, provision of equal access to cancer care is intended to be achieved via secondary medical areas (SMAs). However, the percentage of patients receiving care within the residential area varies by SMA in Osaka Prefecture. We aimed to assess the effect size of factors associated with patient mobility, and whether patient mobility was affected by the COVID-19 pandemic.

Faster surgery initiation in oral cancer patients during the COVID-19 pandemic in Osaka, Japan.

Background: We investigated the impact of the COVID-19 pandemic on oral cancer (OC), comparing diagnosis and number of pre-operative days in the diagnosis of OC in 2019 (pre-COVID-19) and that in 2020 (during the COVID-19 pandemic).

Methods: Using data from a cancer registry-based study on the impact of COVID-19 on cancer care in Osaka (CanReCO), we collected details of sex, age, residential area, cancer site, date of diagnosis, clinical stage at first treatment and number of pre-operative days in OC patients.

Results: A total of 1470 OC cases were registered.

Patterns of staging, treatment, and mortality in gastric, colorectal, and lung cancer among older adults with and without preexisting dementia: a Japanese multicentre cohort study.

Background: Little is known about dementia's impact on patterns of diagnosis, treatment, and outcomes in cancer patients. This study aimed to elucidate the differences in cancer staging, treatment, and mortality in older cancer patients with and without preexisting dementia.

Methods: Using cancer registry data and administrative data from 30 hospitals in Japan, this multicentre retrospective cohort study examined patients aged 65-99 years who were newly diagnosed with gastric, colorectal, or lung cancer in 2014-2015.

Impact of coexisting diabetes on survival and risk of developing second primary cancer in diabetes patients receiving drug therapy: A multicenter retrospective cohort study of patients with cancer in Japan.

Aims/introduction: We investigated the association between coexisting diabetes at the time of cancer diagnosis, and the overall survival and incidence of second primary cancer in patients with cancer and receiving drug therapy for diabetes.

Materials And Methods: We used cancer registry and administrative data of patients diagnosed with cancer at designated cancer care hospitals in Osaka Prefecture between 2010 and 2015. The presence of diabetes was identified from the prescription records of antidiabetic drugs in Diagnosis Procedure Combination System data.

Socioeconomic disparities in cancer survival: Relation to stage at diagnosis, treatment, and centralization of patients to accredited hospitals, 2005-2014, Japan.

Background: Cancer survival varies by socioeconomic status in Japan. We examined the extent to which survival disparities are explained by factors relevant to cancer control measures (promoting early-stage detection, standardizing treatment, and centralizing patients to government-accredited cancer hospitals [ACHs]).

Methods: From the Osaka Cancer Registry, patients diagnosed with solid malignant tumors during 2005-2014 and aged 15-84 years (N = 376,077) were classified into quartiles using the Area Deprivation Index (ADI).

Diagnosis and treatment of digestive cancers during COVID-19 in Japan: A Cancer Registry-based Study on the Impact of COVID-19 on Cancer Care in Osaka (CanReCO).

Background: The coronavirus disease 2019 (COVID-19) affected cancer care in Japan, but the detailed impact on cancer diagnosis and treatment is not well-understood. We aimed to assess the impact of COVID-19 on digestive cancer care in Osaka Prefecture, which has a population of 8.8 million.

Trends in age-standardised net survival of stomach cancer by subsite and stage: A population-based study in Osaka, Japan, 2001-2014.

Introduction: The burden of stomach cancer remains high, particularly among Asian countries. Although Japan is known to achieve high survival from stomach cancer, little is known regarding the survival trends for recent years and survival by subsite and stage. We report age-standardised 1-, 3-, 5- and 10-year net survival for patients diagnosed with stomach cancer in Osaka, Japan.

Socioeconomic gaps over time in colorectal cancer survival in England: flexible parametric survival analysis.

Background: Despite persistent reports of socioeconomic inequalities in colorectal cancer survival in England, the magnitude of survival differences has not been fully evaluated.

Methods: Patients diagnosed with colon cancer (n=68 169) and rectal cancer (n=38 267) in England (diagnosed between January 2010 and March 2013) were analysed as a retrospective cohort study using the National Cancer Registry data linked with other population-based healthcare records. The flexible parametric model incorporating time-varying covariates was used to assess the difference in excess hazard of death and in net survival between the most affluent and the most deprived groups over time.

Exploring socioeconomic differences in surgery and in time to elective surgery for colon cancer in England: Population-based study.

Background: A persistent socioeconomic gap in colon cancer survival is observed in England. Provision of cancer care may also vary by socioeconomic status (SES). We investigated population-based data to explore differential surgical care by SES.

Modelling the cost-effectiveness of a rapid diagnostic test (IgMFA) for uncomplicated typhoid fever in Cambodia.

Typhoid fever is a common cause of fever in Cambodian children but diagnosis and treatment are usually presumptive owing to the lack of quick and accurate tests at an initial consultation. This study aimed to evaluate the cost-effectiveness of using a rapid diagnostic test (RDT) for typhoid fever diagnosis, an immunoglobulin M lateral flow assay (IgMFA), in a remote health centre setting in Cambodia from a healthcare provider perspective. A cost-effectiveness analysis (CEA) with decision analytic modelling was conducted.
