Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
Objetivos: El objetivo fue describir las características demográficas, histopatológicas, biología molecular tumoral y estadificación de los pacientes con cáncer de pulmón de célula no pequeña atendidos entre diciembre de 2013 y diciembre 2018 en el Instituto Nacional de Cancerología. Métodos: Estudio descriptivo de corte transversal Resultados: Se incluyeron 392 pacientes con cáncer de pulmón de célula no pequeña, la mediana de edad fue 65.9 años (rango, 28,9 a 88,9 años). 198(50,5%) pacientes fueron mujeres, obteniendo una relación hombre mujer 1:1. El 90.6% de los casos eran mayores de 50 años. Antecedente de tabaquismo se presentó en 211(53,8%) pacientes, 75.8% de la población masculina y 32,3% de la población femenina eran fumadores. El adenocarcinoma se encontró en 293(74,7%) pacientes y el carcinoma escamocelular en 73(18,6%) pacientes. La estadificación patológica fue: estadío I en 22(5,6%) pacientes, estadío II en 18(4,6%), estadío III en 40(10,2%) pacientes, estadío IV en 311(79,3%) pacientes y no hubo dato en 1 solo paciente. Se detectó la mutación del EGFR en 21,2% de los pacientes. Los reordenamientos de ALK se identificaron en 4,6% de los pacientes y el PDL 1 solo se midió en el 9% de la población. Conclusiones: este estudio nos muestra el panorama general del cáncer de pulmón de célula no pequeña en la población colombiana, en donde la mayoría de los pacientes se diagnostican en estadios avanzados de la enfermedad y nos expone la necesidad de nuevas estrategias para la detección temprana y el acceso oportuno de los pacientes con cáncer de pulmón.
Patient: Female, 59-year-old Final Diagnosis: Melanoma malignant • mucosal melanoma Symptoms: Cough • hemoptysis • weigh loss Medication: — Clinical Procedure: Lymph node excision • pulmonary bilobectomy Specialty: Oncology • Surgery Objective: Rare disease Background: Primary melanoma of the lung is a rare tumor that represents 0.01% of primary lung tumors, with only 40 cases reported in the literature. Mucosal melanomas are tumors with a biological and clinical presentation that differs from that of cutaneous melanomas; therefore, the therapeutic approach differs as well. Survival rates of patients with primary melanoma of the lung are much lower than those of patients with cutaneous melanoma, and there are no diagnostic or treatment guidelines for this entity. Radical surgery is the treatment of choice when disease is resectable. The effectiveness of current established treatments for cutaneous melanoma (eg, immunotherapy and targeted therapy) is unknown in this particular subgroup. Case Report: We present the case of a patient who presented with cough and hemoptysis. The fiberoptic bronchoscopy revealed an endobronchial mass and the computed tomography images suggested an unresectable mass. The patient was initially diagnosed with an unresectable primary lung melanoma with a clinical stage IIIB (T4N2M0). This lesion achieved partial response after treatment with Pembrolizumab, which allowed radical surgery to be performed, achieving complete resection with negative margins and adequate postoperative evolution. Despite the delays in our health care system, she is currently alive and disease-free more than 24 months after diagnosis. Conclusions: Immunotherapy can reduce the size of mucosal melanoma to the point that it can be resectable and this therapeutic approach increases the survival opportunities of these patients.
