ABSTRACT

PURPOSE: Brachytherapy (BT) for cervix cancer was listed as a level I priority and reduced number of implants and multiple fractions were recommended during COVID-19 pandemic. We present early clinical outcome of this approach. METHODS AND MATERIALS: Patients treated with (chemo)radiotherapy and BT with single implant and multiple fractions BT were included. Treatment protocol included 3-5 fractions of 5-8.5 Gy with an aim to achieve point A dose of 70 Gy EQD210Gy (or HRCTV dose of >80 Gy EQD210Gy) in those undergoing intracavitary (IC) and HRCTV dose >85 Gy EQD2 10Gy in patients undergoing Intracavitary-Interstitial (IC/IS) whereas maintaining bladder (B2cc), rectum (R2cc), sigmoid (S 2cc) doses of 90, 75, and 75 Gy EQD23Gy. Time to event analysis was used to report oncological endpoints. Toxicity was reported using crude proportions. RESULTS: From April 2020 to March, 2021, 64 patients with stage IB2-IV received single implant and multi-fraction BT after external radiation of 45 Gy/25 fractions/5 weeks. Only 76.7% (n = 49) received concurrent chemotherapy. Median overall treatment time (OTT) was 56 days (38-131 days). Overall, 62.5% (n = 40) patients received IC and 37.5% (n = 24) received IC+IS. The median HRCTV was 34.7 cc (IQR 25-41). Median (IQR) point A dose, HRCTV D90, B2cc, R2cc, and S2cc for those undergoing IC was 74 Gy (71-78), 80 Gy (73-84), 86 Gy (82-89), 70 Gy (65-74), 65 Gy (59-73) respectively. For the IC+IS cohort, HRCTV D90, B2cc, R2cc, and S2cc was 84 Gy (78-89 Gy), 89 Gy (86-92), 70 Gy (67-74), 68 Gy (59-76). At a median follow-up of 16 months (5-27) the 2-year local control, pelvic control, cause specific and overall survival was 88%, 85.3%, 92.2%, and 81.3% respectively. Late gastrointestinal and genitourinary grade ≥III toxicities were 14% and 1.5% each. CONCLUSIONS: Abbreviated BT outcomes are encouraging for oncological outcomes despite delays in overall treatment time and omission of chemotherapy. Further mature follow up is needed.

ABSTRACT

PURPOSE: To evaluate stress levels among the health care workers (HCWs) of the radiation oncology community in Asian countries. METHODS: HCWs of the radiation oncology departments from 29 tertiary cancer care centers of Bangladesh, India, Indonesia and Nepal were studied from May 2020 to July 2020. A total of 758 eligible HCWs were identified. The 7-Item Generalized Anxiety Disorder, 9-Item Patient Health Questionnaire, and 22-Item Impact of Events Scale-Revised were used for assessing anxiety, depression, and post-traumatic stress disorder. Univariate and multivariate analysis was done to identify the causative factors affecting mental health. RESULTS: A total of 758 participants from 794 HCWs were analyzed. The median age was 31 years (IQR, 27-28). The incidence of moderate to severe levels of anxiety, depression, and stress was 34.8%, 31.2%, and 18.2%, respectively. Severe personal concerns were noticed by 60.9% of the staff. On multivariate analysis, the presence of commonly reported symptoms of COVID-19 during the previous 2 weeks, contact history (harzard ratio [HR], 2.04; CI, 1.15 to 3.63), and compliance with precautionary measures (HR, 1.69; CI, 1.19 to 2.45) for COVID-19 significantly predicted for increasing anxiety (HR, 2.67; CI, 1.93 to 3.70), depression (HR, 3.38; CI 2.36 to 4.84), and stress (HR, 2.89; CI, 1.88 to 4.43) (P < .001). A significant regional variation was also noticed for anxiety, stress, and personal concerns. CONCLUSION: This survey conducted during the COVID-19 pandemic revealed that a significant proportion of HCWs in the radiation oncology community experiences moderate to severe levels of anxiety, depression, and stress. This trend is alarming and it is important to identify and intervene at the right time to improve the mental health of HCWs to avoid any long-term impacts.

ABSTRACT

PURPOSE: Delivery of cancer care during the pandemic required adopting various changes in the standard management. We analyzed the impact of the first wave of the COVID-19 pandemic on radiation oncology treatment practices at Tata Memorial Hospital in India. MATERIALS AND METHODS: From March 1 to October 31, 2020, all consecutive patients who attended the radiation oncology department for radiotherapy treatment were included in this study. Electronic medical records, patient files, and telephonic consult were used to collect patient's data including changes in the standard treatment practice, COVID-19 testing and its results, and subsequent impact on radiotherapy treatment. Comparison was done with the same period data of 2019 for the number of the caseload, radiotherapy regimen, referral rates, and noncompliance rates. RESULTS: Our study included 4,256 patients with a median age of 52 years (interquartile range 41-61 years). There was a significant drop in the new-patient registrations (approximately 63%), radiotherapy consultations (44.9%), and referrals to other centers (27.8%). The reduction in the caseload was highest for genitourinary cases (-58.5%) and the lowest for breast cases (-11.5%) when compared with the 2019 cohort. Among those treated with radical intent, the noncompliance rate was 15%. Hypofractionation was the commonly adopted regimen across all sites. Compared with 2019, the maximum reduction in the average fractions per patient was seen in the breast cancer cases (-8.2 fraction), followed by genitourinary cases (-4.9 fraction). Of the 27.8% of patients tested for COVID-19, 13.4% turned positive and 3.4% died due to the disease. CONCLUSION: The COVID-19 pandemic adversely affected the number of radiotherapy consultations and treatments at our institute. However, our department offered uninterrupted services despite grave challenges. Hypofractionated regimen was used across disease sites to minimize patient visits and allow planned treatment completion. Radiotherapy was delivered safely, and patients experienced low rates of COVID positivity during radiotherapy and even lower mortality.

ABSTRACT

PURPOSE: To report real-world compliance to radiation in gynecologic cancers during the complete lockdown phase of COVID-19 pandemic. METHODS AND MATERIALS: From March 23, 2020, until June 30, 2020, complete lockdown was imposed in India. During this period there was restructuring of cancer care and radiation oncology department due to operational policies prevalent in the institution, and the care for gynecological cancer was based on the evolving international recommendations. Institutional review board approval was obtained to audit patterns of care during the complete lockdown phase. Descriptive variables were used to report on patient characteristics, compliance, delays, toxicity, and observed deviations in recommended care. RESULTS: During the lockdown period spanning 100 days, treatment of 270 and telephonic follow-up of 1103 patients with gynecological cancer was undertaken. Of 270 new patients, due to travel restrictions, 90 patients were referred to the facilities in vicinity of their residence. Of the remaining 180 patients, 138 were planned for complete treatment at our institution and 42 were referred to our center for brachytherapy. Of 138 patients, only 106 (76%) completed the planned external radiation. Twenty-four (26%) patients completed full course of concurrent chemotherapy, 11 (12%) received chemotherapy dose reduction, and 57 (62%) received no concurrent chemotherapy. Treatment delay of up to 3 weeks was noted in 8.6% patients due to COVID-19 infection. No grade 4 to 5 acute sequelae were observed. No excess adverse effects were observed in high-risk population. Low rate of symptom burden was observed among 1103 patients on telephonic follow-up. With 100 (9.6%) patients reporting symptoms, among these, 54% (54 of 100) had complete resolution of symptoms within 4 weeks of teleconsultation, and 10% had disease progression. CONCLUSIONS: Low compliance with planned treatment was observed for radiation and concurrent chemotherapy due to lockdown and fear of contracting COVID-19 and will likely lead to increased risk of cancer-related mortality. Rapid restructuring of care is needed to prevent the same as COVID-19 pandemic further evolves.

ABSTRACT

The incidence of head and neck squamous cell carcinoma (HNSCC) is increasing worldwide, with over three quarters of cases now diagnosed in low and middle-income countries (LMICs) with resource-constraints. Loco-regional recurrence remains the predominant pattern of failure mandating adequate local therapy for acceptable loco-regional control and survival. There is high-quality evidence that intensification of treatment by either by adding concurrent chemotherapy or by altering radiotherapy (RT) fractionation improves outcomes in the curative-intent management of loco-regionally advanced HNSCC. Even conservative estimates indicate that >50% of patients in LMIC are unlikely to get access to timely RT, which will only get compounded with the coronavirus disease (COVID)-19 pandemic. The radiation oncology community has been systematically testing altered fractionation schedules in several solid cancers (breast, lung, and head-neck), given the cost-effectiveness, convenience, and compliance to short-course RT regimens. Radiobiological modelling suggests that standard fractionation of 6-7 weeks in HNSCC can be compressed safely into a 4-week schedule to counter accelerated repopulation by increasing the dose per fraction and delivering 5 fractions per week which is currently being tested in the ongoing multicentric trial of hypo- vs normo-fractionated accelerated RT (HYPNO study). Herein, we discuss the radiobiological basis of curative-intent hypofractionated-accelerated RT schedule delivering 55 Gy in 20 fractions over 4 weeks in HNSCC followed by critical appraisal of the published literature on such regimens with concurrent systemic therapy and its inherent resource-sparing potential applicable across large parts of the world particularly in the context of the ongoing COVID-19 pandemic.

ABSTRACT

The practice of radiation oncology requires stringent adherence to specific steps and principles designed to minimize exposure of an individual to unnecessary doses of radiation. The basic principles of such measures to reduce the risk of exposure and limit the doses of irradiation follow the "as low as reasonably achievable " or ALARA principle by using the concepts of time, distance and shielding. Potential exposures in radiation oncology are controlled through combination of optimal design and installation of radiation delivery equipment with well-defined standard operating procedures (SOPs). In the modern era of viral pandemics, similar principles can also be applied toward prevention of viral transmission and protection of populations at risk. In the ongoing COVID-19 pandemic, the probability of an individual getting infected is dependent on the viral load that an individual is exposed to in public spaces over a period of time. All prevention and control measures are based on preventing any such exposure to the virus, that can be achieved through limiting space for movement of the virus, using barriers and increasing distance to vulnerable surfaces, and limiting the duration of exposure. Apart from adhering to the laid-down provisions of a lock-down, preventive measures recommended for the general public include maintaining hand-hygiene, social distancing, and using facemasks to break the chain of transmission. Appropriate triage and customization of treatment protocols can help curtail hospital visits and time-spent by cancer patients during pandemic times, thereby reducing their risk of exposure as well as allowing efficient utilization of resources. The outbreak of the contagious COVID-19 pandemic threatens to disrupt healthcare systems globally with its unprecedented challenges. However, despite all the difficulties and hardships, it has also enabled new ways of learning and communication, which are likely to persist even in the post-COVID world.
