ABSTRACT
Background Polish and Australian randomized studies compared short-course radiotherapy (RT) with immediate surgery and long-course chemoradiotherapy (CRT) with delayed surgery. In these studies, similar long-term survival and local control have been reported for both these approaches, but pathological complete response (pCR) is not better with short-course RT. Moreover, studies have shown better tumor downstaging with delayed surgery. In this context, the use of short-course RT with delayed surgery may have some advantages and needs to be tested in clinical trials. Patients and Methods This was a two-arm, prospective, observational study, in which preoperative short-course RT followed by two cycles of chemotherapy was compared with the conventional neoadjuvant CRT in locally advanced rectal cancer. The primary end points were the rate of complete response and toxicity profile. The secondary end points were the rate of R0 resection, overall survival, and progression-free survival. The data obtained from the two arms were analyzed using Pearson's chi-square test to determine the statistical significance between the two treatment arms. Results The pCR rate was 6.7% in the study arm and 0 in the control arm ( p = 0.343). The RO resection rates were 92.8 and 92.3% in the study and control arms, respectively. The rates of grade 3and 4 acute toxicity in the study and control arms were 14.2 and 61.5%, respectively ( p = 0.011). The rates of grade 3 and 4 late toxicity in the study and control arms were 21.4 and 15.3%, respectively ( p = 0.686). Conclusions The pCR rates and the late toxicities in both arms are comparable. The major advantages of the 5 × 5 Gy regimen with chemotherapy in a neoadjuvant setting are a significant reduction in acute toxicities and better patient compliance along with similar efficacy as that of the standard regimen.
ABSTRACT
PURPOSE: The entire world is currently facing a devastating crisis due to growing coronavirus pandemic, which was declared as a public health emergency by the World Health Organization on March 11, 2020. Management of cancer patients at this time is an overwhelming task. This study highlights our experience in the management of patients of gynecological malignancies over a period of 2 months during the COVID-19 pandemic. METHODS: Patients of confirmed gynecological malignancies who visited our outpatient clinic and those who received radiotherapy/chemotherapy in March and April 2020 were included for analysis. Guidelines issued by the National Institute of Health and Care Excellence, National Health Service, MD Anderson Cancer Centre and those by young oncologists in Italy were followed with minor modifications while managing the logistics and health worker safety. RESULTS: A total of 160 patients were treated in our department during this time period. In total, 44.4% of patients on treatment had associated comorbidities that imposed an additional risk. One hundred twenty-three patients continued treatment with their initial plan of radiotherapy or chemotherapy. New patients were prioritized based on the severity of clinical symptoms and whether the expected outcome would significantly affect their survival and quality of life. Patients were monitored for the development of treatment-related toxicities and COVID-19-related symptoms. CONCLUSIONS: All oncology personnel need to identify the correct balance between risks and benefit and then proceed with further management. Thus, it is essential to cautiously select patients for treatment, minimizing the risk of exposure but adequately addressing the underlying disease.
