A national survey was conducted to obtain information about the use of image-guided radiotherapy (IGRT) techniques and IGRT dose measurement methods being followed at Indian radiotherapy centers. A questionnaire containing parameters relevant to use of IGRT was prepared to collect the information pertaining to (i) availability and type of IGRT delivery system, (ii) frequency of image acquisition protocol and utilization of these images for different purpose, and (iii) imaging dose measurement. The questionnaire was circulated to 75 hospitals in the country having IGRT facility, and responses of 51 centers were received. Survey results showed that among surveyed hospitals, 86% centers have IGRT facility, 78% centers have kilo voltage three-dimensional volumetric imaging. 75% of hospitals in our study do not perform computed tomography dose index measurements and 89% of centers do not perform patient dose measurements. Moreover, only 29% physicists believe IGRT dose is additional radiation burden to patient. This study has brought into focus the need to design a national protocol for IGRT dose measurement and development of indigenous tools to perform IGRT dose measurements.
Introduction:
COVID-19 illness caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) virus has been declared a pandemic by the World Health Organization in March 2020. It had an overwhelming effect on health-care delivery in India. We report the 5 months, April–September 2020, experience in our radiotherapy (RT) department.
Methods:
Since April–September 2020, we registered 184 cancer patients with various site diseases for RT/chemoradiation treatment for curative/palliative therapy. Preregistration and weekly once during treatment period all underwent throat/nasopharynx swab testing with reverse transcription polymerase chain reaction. Dedicated infection prophylaxis was carried for patients and staff.
Results:
Of the 184 patients, 10.9% (20/184) swab results were positive for SARS-CoV-2. With appropriate COVID-19 care and quarantine, 18 patients completed the planned RT. Two died with COVID-19 infection illness and progressive locoregional cancer. We observed no excess acute RT/chemoradiation effects in this group due to infection.
Conclusions:
Our 5-month experience in this COVID-19 pandemic period reveals that RT treatment, COVID-19 care, and quarantine can be done with dedicated infection protective measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
