Recommendations on intervention for hepatobiliary oncological surgery during the COVID-19 pandemic. / Recomendaciones de actuación en cirugía oncológica hepatobiliopancreática durante la pandemia COVID-19.

The SARS-CoV-2 (COVID-19) pandemic requires an analysis in the field of oncological surgery, both on the risk of infection, with very relevant clinical consequences, and on the need to generate plans to minimize the impact on possible restrictions on health resources. The AEC is making a proposal for the management of patients with hepatopancreatobiliary (HPB) malignancies in the different pandemic scenarios in order to offer the maximum benefit to patients, minimising the risks of COVID-19 infection, and optimising the healthcare resources available at any time. This requires the coordination of the different treatment options between the departments involved in the management of these patients: medical oncology, radiotherapy oncology, surgery, anaesthesia, radiology, endoscopy department and intensive care. The goal is offer effective treatments, adapted to the available resources, without compromising patients and healthcare professionals safety.

[Medical diagnosis and treatment strategies for malignant tumors of the digestive system during the outbreak of COVID-19].

Since the outbreak of COVID-19 in December 2019, the diagnosis and treatment of patients with cancer have been facing great challenges. Although oncologists are not fighting on the front line to against the epidemic, during this special period, we should not only protect patients, their families and medical staff from the infection of novel coronavirus, but also minimize the impact of the epidemic on the diagnosis and the treatment of patients with cancer. Combining the guidelines for diagnosis and treatment of tumors with our clinical experience, in this epidemic period, we discuss the strategies for diagnosis, treatment, and follow-up of malignant tumors of the digestive system in this article.

[Surgical treatment strategy for digestive system malignancies during the outbreak of COVID-19].

The outbreak of COVID-19 occurred in Wuhan, Hubei province of China, at the end of 2019, and spread rapidly across the country. After the outbreak of this disease, the overwhelming majority of cities have launched the "first level response" and the regular diagnosis and treatment of cancer patients are greatly affected. The digestive systemic cancer is the most common malignancy. Most patients are diagnosed in the advanced stage with poor prognosis. The epidemic of COVID-19 poses new challenges to diagnosis and treatment of the patients with digestive system malignancies. Based on the fully understanding of the characteristics of digestive system tumors, we should change the treatment strategy and adopt more reasonable treatment strategy timely during the epidemic period to minimize the adverse effects of the epidemic of COVID-19 on the treatment.

Surgical decision-making and prioritization for cancer patients at the onset of the COVID-19 pandemic: A multidisciplinary approach.

In the midst of the coronavirus disease 2019 (COVID-19) pandemic, governmental agencies, state medical boards, and healthcare organizations have called for restricting "elective" operations to mitigate the risk of transmission of the virus amongst patients and healthcare providers and to preserve essential resources for potential regional surges of COVID patients. While the fear of delaying surgical care for many of our patients is deeply challenging for us as cancer care providers, we must balance our personal commitment to providing timely and appropriate oncologic care to our cancer patients with our societal responsibility to protect our patients (including those on whom we are operating), co-workers, trainees, families, and community, from undue risks of contracting and propagating COVID-19. Herein, we present guidelines for surgical decision-making and case prioritization developed among all adult disease specialties in the MD Anderson Cancer Center Departments of Surgical Oncology and Breast Surgical Oncology in Houston, Texas.

Strategy for the practice of digestive and oncological surgery during the Covid-19 epidemic.

The Covid-19 pandemic is changing the organization of healthcare and has a direct impact on digestive surgery. Healthcare priorities and circuits are being modified. Emergency surgery is still a priority. Functional surgery is to be deferred. Laparoscopic surgery must follow strict rules so as not to expose healthcare professionals (HCPs) to added risk. The question looms large in cancer surgery-go ahead or defer? There is probably an added risk due to the pandemic that must be balanced against the risk incurred by deferring surgery. For each type of cancer-colon, pancreas, oesogastric, hepatocellular carcinoma-morbidity and mortality rates are stated and compared with the oncological risk incurred by deferring surgery and/or the tumour doubling time. Strategies can be proposed based on this comparison. For colonic cancers T1-2, N0, it is advisable to defer surgery. For advanced colonic lesions, it seems judicious to undertake neoadjuvant chemotherapy and then wait. For rectal cancers T3-4 and/or N+, chemoradiotherapy is indicated, short radiotherapy must be discussed (followed by a waiting period) to reduce time of exposure in the hospital and to prevent infections. Most complex surgery with high morbidity and mortality-oesogastric, hepatic or pancreatic-is most often best deferred.
