ABSTRACT
Myanmar, a nation situated between India, China and Southeast Asia, has long histories of colonialism, violence, and resource extraction. This special issue introduction, written in the midst of Myanmar's 2021 military coup and the COVID-19 pandemic, offers two critical and feminist interventions–‘remaking' and ‘living with'–to understand the contested and embodied political geographies of extractive resource frontiers in Myanmar. ‘Remaking' focuses on the long roots of resource frontiers, underscoring the historical and spatial processes through which Myanmar's plural authorities have restructured diverse territories for accumulation and extraction from the pre-colonial period to the recent ‘democratic transition'. ‘Living with' resource frontiers bring attention to people's everyday lives, and why and how they adapt, resist, comply, suffer and profit from resource frontiers. In bringing together a diverse set of literatures with original empirical research, the articles in this collection offer analyses of Myanmar's pre-coup period that inform contemporary post-coup politics. Together, they demonstrate the material, affective, and embodied nature of resource frontiers as they are (re)made and lived with–in and beyond militarised spaces like Myanmar. © 2022 Taylor & Francis Group, LLC.
ABSTRACT
A PENTEC analysis of published investigations of central nervous system (CNS) subsequent neoplasms (CNS-SN) in childhood cancer survivors who received radiation therapy (RT) to the brain was performed to estimate the effect of RT dose and gender on the risk of CNS-SN following RT. Through the PENTEC initiative, a systematic literature review was performed to identify published data on CNS-SN after prior cranial RT in childhood cancer survivors. Using the Covidence platform 2,156 studies were screened for potential inclusion. The incidences of CNS-SNs, RT dose, age, gender, primary cancer diagnosis, and latent time from primary diagnosis to CNS-SN were extracted, to assess the factors influencing risk for subsequent meningiomas or subsequent malignant CNS tumors (e.g., gliomas). The odds ratio for CNS-SNs in different dose intervals were calculated and excess odds ratio (EOR) per Gy of developing subsequent meningiomas or malignant tumors was estimated using inverse-variance weighted linear regression to model the risk for CNS-SN versus dose. Forty studies of independent patient cohorts provided information on 736 subsequent malignant tumors with average median latency 10.3 years, and 32 studies provided information on 1,035 subsequent meningiomas with average median latency 20.5 years. Dose-response was derived from 6 studies of 248 subsequent malignant tumors and 7 studies of 557 subsequent meningiomas. The pooled EOR/Gy was 0.45 (95% CI: 0.25, 0.66) for meningiomas and 0.16 (95% CI: 0.11, 0.20) for malignant CNS tumors. The average cumulative incidence of developing a meningioma or malignant CNS tumor at 15 years of follow-up was 2.4% (range, 1.2-6.3%) or 0.9% (range, 0.4-1.8%), respectively. Females had a higher risk of meningioma than males (OR=1.5, 95% CI: 1.2, 1.8;6 studies;50,346 patients) whereas no gender difference was seen in risk of malignant tumors (OR=0.9, 95% CI: 0.7, 1.2;4 studies;32,446 patients). This PENTEC systematic review shows a significant radiation dose-response relationship and higher risk among females for meningioma, akin to the general population, and a highly significant but somewhat less steep relationship for subsequent malignant tumors with no effect of gender. Further evaluation of the effect of age and chemotherapy in relation to dose and gender is necessary to elucidate the risk of CNS-SN after RT.
