Prioritization, patient selection, and multimodal perioperative management of colorectal cancer facing health-care system saturation.

OBJECTIVE: The aim is to analyze the usefulness of pre-operative COVID-19 screening to detect asymptomatic patients, the capability of our patient selection algorithm to detect patients with more advanced tumors and the results of colorectal cancer surgery managed with a multimodal approach. We propose the use of a preoperative patient selection algorithm to prioritize the surgical treatment of patients with worse oncological prognosis and lower perioperative risk in situations of health system saturation. MATERIAL AND METHODS: Prospective descriptive study including 71 patients operated on for colorectal cancer during COVID-19's high incidence period. A division was made into two periods of time that were later compared with the aim of assessing whether the scale used identified those patients with lower surgical risk and higher oncological priority for their priority scheduling. RESULTS: Post-operative severe acute respiratory syndrome coronavirus 2 infection occurred in one patient (1.4%). Pre-operative polymerase chain reaction detected one asymptomatic patient (3%). Tumor stage was ≥ IIIA in 39% and node positive in 39% of patients in the first period, while 26% and 21% in the second period, respectively (p = 0.320; p = 0.179), without increasing the surgical stay or complications. Median hospital stay was 5 days. Grades III and IV morbidity were 4.4% and 1.4%. CONCLUSION: The use of an algorithm and Patient Selection Scale can detect patients with more advanced tumors to be operated before. Multimodal management/ERAS have a role in achieving short stay and low morbidity.

OBJETIVO: El retraso terapéutico derivado de la saturación del Sistema sanitario conlleva un peor pronóstico oncológico y un aumento de complicaciones en el cáncer colorrectal. Proponemos el usode un algoritmo de selección de pacientes de forma preoperatoria para priorizar el tratamiento quirúrgico de los pacientes con peor pronóstico oncológico y menor riesgo perioperatorio. MATERIAL Y MÉTODOS: Realizamos un estudio descriptivo prospectivo de 71 pacientes intervenidos por cáncer colorrectal durante el periodo de máxima incidencia por COVID. Se realizó una división en dos periodos de tiempo que fueron comparados posteriormente con el objetivo de valorar si la escala utilizada conseguía identificar aquellos pacientes con menor riesgo quirúrgico y mayor prioridad oncológica para su programación prioritaria. RESULTADOS: Utilizando la escala de priorización de pacientes (PSS) observamos que el estadio tumoral fue mayor de IIIA en un 39% de los pacientes con un 39% de ganglios positivos en un primer periodo, frente a un 26% y 21% en un segundo periodo (p = 0.320; p = 0.179) de tiempo, sin aumentar la estancia operatoria ni las complicaciones. Se realizaron dos métodos de cribado de COVID-19 en dos periodos de tiempo, detectando un 3% de pacientes asintomáticos de forma preoperatoria con PCR, y documentando un 1.4% de infección por COVID postoperatoria. CONCLUSIONES: Ante la saturación del sistema sanitario, la utilización de protocolos y algoritmos para selección de pacientes con cáncer colorrectal puede ayudar a dar preferencia quirúrgica a aquellos casos que no deben ser demorados.

The impact of SARS-CoV-2 infection on the surgical management of colorectal cancer: lessons learned from a multicenter study in Spain.

OBJECTIVE: the aim of the study was to analyze the management of colorectal cancer (CRC) patients diagnosed with CRC or undergoing elective surgery during the period of the SARS-CoV-2 pandemic. MATERIAL AND METHODS: a multicenter ambispective analysis was performed in nine centers in Spain during a four-month period. Data were collected from every patient, including changes in treatments, referrals or delays in surgeries, changes in surgical approaches, postoperative outcomes and perioperative SARS-CoV-2 status. The hospital's response to the outbreak and available resources were categorized, and outcomes were divided into periods based on the timeline of the pandemic. RESULTS: a total of 301 patients were included by the study centers and 259 (86 %) underwent surgery. Five hospitals went into phase III during the peak of incidence period, one remained in phase II and three in phase I. More than 60 % of patients suffered some form of change: 48 % referrals, 39 % delays, 4 % of rectal cancer patients had a prolonged interval to surgery and 5 % underwent neoadjuvant treatment. At the time of study closure, 3 % did not undergo surgery. More than 85 % of the patients were tested preoperatively for SARS-CoV-2. A total of nine patients (3 %) developed postoperative pneumonia; three of them had confirmed SARS-CoV-2. The observed surgical complications and mortality rates were similar as expected in a usual situation. CONCLUSIONS: the present multicenter study shows different patterns of response to the SARS-CoV-2 pandemic and collateral effects in managing CRC patients. Knowing these patterns could be useful for planning future changes in surgical departments in preparation for new outbreaks.
