  • Unlocking economic gains

    Open AccessEkkasit Tharavichitkul, Imjai Chitapanarux et al.ARTICLEFrontiers in Public Health2026

    Objective: This study aims to bridge the existing gap in knowledge by assessing the financial impact of image-guided brachytherapy (IGBT) in the management of cervical cancer in Thailand. Methods: A web-based questionnaire was developed in 2019 to collect data from 14 radiotherapy centers across all regions of Thailand. The survey gathered information on the use of brachytherapy for cervical cancer treatment, encompassing both conventional brachy…

  • Time-varying exposure to ambient air pollution and mortality among colon cancer patients in northern Thailand

    Open AccessTaned Chitapanarux, Patrinee Traisathit et al.ARTICLEFrontiers in Public Health2026

    Background Northern Thailand experiences severe annual air pollution (PM 2.5 > 35 μg/m 3 ), primarily due to agricultural burning. While ambient PM 2.5 has been linked to gastrointestinal cancer deaths, its effect on colon cancer survival in high-exposure areas remains understudied. Methods In this 15-year retrospective cohort study, we used data on 5,018 patients with colon cancer (2003–2018) obtained from the Chiang Mai Cancer Registry. Time-va…

  • Lung adenocarcinoma risk in an area with seasonal high PM2.5 exposure

    Open AccessPak Thaichana, Patumrat Sripan et al.ARTICLEFrontiers in Public Health2026

    Background Air pollution exposure has been associated with increased lung cancer risk globally. However, evidence linking fine particulate matter with an aerodynamic diameter of ≤2.5 micrometers (PM 2.5 ) to adenocarcinoma, the most common histological subtype of lung cancer, using the real-world data remains limited in Southeast Asia populations where air pollution levels are rising. This study aimed to investigate the association between averag…

  • Estimating proton beam therapy utilization and Investment in Thailand

    Open AccessImjai Chitapanarux, Ekkasit Tharavichitkul et al.ARTICLEFrontiers in Public Health2025

    Background: Thailand's first Proton Beam Therapy (PBT) center became operational in August 2021. Given the high costs and specialized expertise required, evaluating the clinical and economic implications of PBT and planning for its expansion are essential for Thailand's healthcare system. Methods: This study projected national PBT demand using data from the Thai PBT center, the Thai Association of Radiation Oncology (THASTRO), national cancer reg…

  • Air pollutants and primary liver cancer mortality

    Open AccessNatthapat Thongsak, Taned Chitapanarux et al.ARTICLEFrontiers in Public Health2024

    Introduction Northern Thailand experiences high levels of air pollution in the dry season due to agricultural waste burning and forest fires. Some air pollutants can enter the bloodstream, and the liver has the role of detoxifying these along with other harmful substances. In this study, we assessed the effects of long-term exposure to air pollutants on liver cancer mortality in this area. Methods A cohort of 10,859 primary liver cancer patients …

  • Impact of Residential Concentration of PM2.5 Analyzed as Time-Varying Covariate on the Survival Rate of Lung Cancer Patients

    Open AccessNawapon Nakharutai, Patrinee Traisathit et al.ARTICLEInternational Journal of…2022

    Air pollutants, especially particulate matter (PM) ≤ 2.5 μm (PM2.5) and PM ≤ 10 μm (PM10), are a major concern in upper northern Thailand. Data from a retrospective cohort comprising 9820 lung cancer patients diagnosed from 2003 to 2018 were obtained from the Chiang Mai Cancer Registry, and used to evaluate mortality and survival rates. Cox proportional hazard models were used to identify the association between the risk of death and risk factors…

  • Disparities in the change of cervical cancer mortality rate between urban and rural Chiang Mai in the era of universal health care and the Thai national screening program

    Open AccessPatumrat Sripan, Imjai Chitapanarux et al.ARTICLEInternational Journal for Equity…2021

    The UHC and national cervical cancer screening program in Thai women may have contributed to the reduction of the mortality rate of cervical cancer in the screening target age group. However, this reduction was primarily in urban areas of Chiang Mai, and there was no significant impact on mortality in more rural areas. These results suggest that the reasons for this disparity need to be further explored to equitably increase access to cervical ca…

  • Risk patterns of lung cancer mortality in northern Thailand

    Open AccessApinut Rankantha, Imjai Chitapanarux et al.ARTICLEBMC Public Health2018

    There was distinct geographical variation in risk patterns of lung cancer mortality in Thailand. Differences could be related to differences in risk factors such as ground-based radon and air pollution. This study provides a starting point for estimating the spatial pattern of the risk of lung cancer mortality and for examining associations between geographic risk factors and lung mortality for further studies
