ABSTRACT

BACKGROUND: COVID-19 outbreak was declared as a pandemic by the World Health Organization in March 2020. Over the last 3 months, the pandemic has challenged the diagnosis and treatment of all cancer, including rectal cancer. Constraints in resources call for a change in the treatment strategy without compromising efficacy. RECENT FINDINGS: Delivery of shorter treatment schedules for radiotherapy offers advantages like short overall treatment time, improved throughput on the machine, improved compliance and reduced risk of transmission of COVID 19. Other strategies include delaying surgery, reducing the intensity of chemotherapy and adoption of organ preservation approach. CONCLUSION: The curative treatment of rectal cancer should not be hindered during the COVID pandemic, and modifications in the multi-modality treatment will help achieve quality care.

ABSTRACT

Objective: Pelvic high-resolution magnetic resonance imaging (MRI) has now become a standard method for evaluating the efficacy of neoadjuvant treatment for locally advanced rectal cancer (LARC). However, this traditional morphological qualitative assessment method based on T2-weighted imaging (T2WI) is not effective in predicting pathological complete remission (pCR). The purpose of this study is to investigate whether combining the magnetic resonance tumor regression grade (mrTRG) with apparent diffusion coefficient (ADC) can improve diagnostic value for pCR after preoperative neoadjuvant chemoradiotherapy (nCRT) of LARC. Methods: This was a diagnostic study. Clinicopathological data of 134 LARC patients who received nCRT and radical surgery in the First Affiliated Hospital of Kunming Medical University from January 2017 to December 2019 were retrospectively analyzed. All the patients underwent MRI which included T2WI and DWI sequences before and 8 weeks after nCRT. Two radiologists independently drew ROIs on T2WI and DWI to estimate mrTRG stage and calculate the mean ADC value. Receiver operating characteristics (ROC) method was applied to evaluate the predict value of mrTRG combined with mean ADC value for pCR. Results: Of 134 LARC patients, 85 were male and 49 were female with median age of 58 (28-82) years. After nCRT, MRI suggested 21 patients (15.7%) had clinical complete remission (cCR), e.g. mrTRG stage 1-2. Postoperative pathology revealed 31 (23.1%) patients had pCR. The evaluations of mrTRG and ADC value by the two readers were highly consistent, and the intra-group correlation coefficients were 0.83 (95% CI: 0.703-0.881) and 0.96 (95% CI: 0.989-0.996), respectively. There was a negative correlation between mrTRG and pCR (r(s)=-0.505, P<0.01), and a positive correlation between mean ADC value and pCR (r(s)=0.693, P<0.01). The ROC curve showed that mrTRG alone had a medium predictive value for pCR, with an area under the curve (AUC) of 0.832 (95% CI: 0.743-0.921); the mean ADC value had a higher predictive value for pCR, with AUC of 0.906 (95% CI: 0.869-0.962). The predictive value of the combined model of mrTRG and ADC value for pCR was significantly better than that of mrTRG alone (P=0.015), and the AUC was 0.908 (95% CI: 0.849-0.968). Conclusion: Both mrTRG and mean ADC value can be non-invasive methods to predict the efficacy of nCRT for LARC. Combining the mean ADC value with mrTRG can result in better pCR prediction.

ABSTRACT

PURPOSE: Today, the rapid outbreak of COVID-19 is the leading health issue. Patients with cancer are at high risk for the development of morbidities of COVID-19. Hence, oncology centers need to provide organ-based recommendations for optimal management of cancer in the COVID-19 era. METHODS: In this article, we have provided the recommendations on management of locally advanced rectal cancer during the COVID-19 pandemic based on our experience in Shohada-e Tajrish Hospital, Iran. RESULTS: We recommend that patients with locally advanced rectal cancer should be managed in an individualized manner in combination with local conditions related to COVID-19. CONCLUSION: Our recommendation may provide a guide for oncology centers of developing countries for better management of locally advanced rectal cancer.

ABSTRACT

The extraordinary spread of the novel coronavirus (COVID-19) has dramatically and rapidly changed the way in which we provide medical care for patients with all diagnoses. Conservation of resources, social distancing, and the risk of poor outcomes in COVID-19-positive cancer patients have forced practitioners and surgeons to completely rethink routine care. The treatment of patients with rectal cancer requires both a multidisciplinary approach and a significant amount of resources. It is therefore imperative to rethink how rectal cancer treatment can be aligned with the current COVID-19 pandemic paradigms. In this review, we discuss evidence-based recommendations to optimize oncological outcomes during the COVID-19 pandemic.
