Colonoscopic-assisted laparoscopic wedge resection versus segmental colon resection for benign colonic polyps: a comparative cost analysis.

AIM: The colonoscopic-assisted laparoscopic wedge resection (CAL-WR) is proven to be an effective and safe alternative to a segmental colon resection (SCR) for large or complex benign colonic polyps that are not eligible for endoscopic removal. This analysis aimed to evaluate the costs of CAL-WR and compare them to the costs of an SCR. METHOD: A single-centre 90-day 'in-hospital' comparative cost analysis was performed on patients undergoing CAL-WR or SCR for complex benign polyps between 2016 and 2020. The CAL-WR group consisted of 44 patients who participated in a prospective multicentre study (LIMERIC study). Inclusion criteria were (1) endoscopically unresectable benign polyps; (2) residual or recurrence after previous polypectomy; or (3) irradically resected low risk pT1 colon carcinoma. The comparison group, which was retrospectively identified, included 32 patients who underwent an elective SCR in the same period. RESULTS: Colonoscopic-assisted laparoscopic wedge resection was associated with significantly fewer complications (7% in the CAL-WR group vs. 45% in the SCR group, P < 0.001), shorter operation time (50 min in the CAL-WR group vs. 119 min in the SCR group, P < 0.001), shorter length of hospital stay (median length of stay 2 days in the CAL-WR group vs. 4 days in the SCR group, P < 0.001) and less use of surgical resources (reduction in costs of 32% per patient), resulting in a cost savings of €2372 (£2099 GBP) per patient (P < 0.001). CONCLUSION: Given the clinical and financial benefits, CAL-WR should be recommended for complex benign polyps that are not eligible for endoscopic resection before major surgery is considered.

Cost-effectiveness of pancreas surveillance: The CDKN2A-p16-Leiden cohort.

BACKGROUND: CDKN2A-p16-Leiden mutation carriers have a high lifetime risk of developing pancreatic ductal adenocarcinoma (PDAC), with very poor survival. Surveillance may improve prognosis. OBJECTIVE: To assess the cost-effectiveness of surveillance, as compared to no surveillance. METHODS: In 2000, a surveillance program was initiated at Leiden University Medical Center with annual MRI and optional endoscopic ultrasound. Data were collected on the resection rate of screen-detected tumors and on survival. The Kaplan-Meier method and a parametric cure model were used to analyze and compare survival. Based on the surveillance and survival data from the screening program, a state-transition model was constructed to estimate lifelong outcomes. RESULTS: A total of 347 mutation carriers participated in the surveillance program. PDAC was detected in 31 patients (8.9%) and the tumor could be resected in 22 patients (71.0%). Long-term cure among patients with resected PDAC was estimated at 47.1% (p < 0.001). The surveillance program was estimated to reduce mortality from PDAC by 12.1% and increase average life expectancy by 2.10 years. Lifelong costs increased by €13,900 per patient, with a cost-utility ratio of €14,000 per quality-adjusted life year gained. For annual surveillance to have an acceptable cost-effectiveness in other settings, lifetime PDAC risk needs to be 10% or higher. CONCLUSION: The tumor could be resected in most patients with a screen-detected PDAC. These patients had considerably better survival and as a result annual surveillance was found to be cost-effective.

Delayed TME Surgery in a Watch-and-Wait Strategy After Neoadjuvant Chemoradiotherapy for Rectal Cancer: An Analysis of Hospital Costs and Surgical and Oncological Outcomes.

BACKGROUND: A watch-and-wait strategy for patients with rectal cancer with a clinical complete response after neoadjuvant chemoradiotherapy is a valuable alternative for rectal resection. However, there are patients who will have residual tumor or regrowth during watch and wait. OBJECTIVE: The aim of this study was to investigate safety and costs for patients who underwent delayed surgery after neoadjuvant chemoradiotherapy. DESIGN: This is a retrospective cohort study with prospectively collected data. SETTINGS: The study was conducted at a large teaching hospital. PATIENTS: Between January 2015 and May 2020, 622 new rectal cancer patients were seen, of whom 200 received neoadjuvant chemoradiotherapy. Ninety-four patients were included, 65 of whom underwent immediate surgery and 29 of whom required delayed surgery after an initial watch-and-wait approach. MAIN OUTCOME MEASURES: Outcome measures included 30-day postoperative morbidity rate, hospital costs. 2-year overall and disease-free survival. RESULTS: There was no difference in length of stay (9 vs 8; p = 0.83), readmissions (27.6% vs 10.0%; p = 0.10), surgical re-interventions (15.0% vs 3.4%; p = 0.16), or stoma-free rate (52.6% vs 31.0%; p = 0.09) between immediate and delayed surgery groups. Hospital costs were similar in the delayed group (€11,913 vs €13,769; p = 0.89). Two-year overall survival (93% vs 100%; p = 0.23) and disease-free survival (78% vs 81%; p = 0.47) rates were comparable. LIMITATIONS: Limitations included small sample size, follow-up time and retrospective design. CONCLUSION: Delayed surgery for regrowth in a watch-and-wait program or for persistent residual disease after a repeated assessment is not associated with an increased risk of postoperative morbidity or a significant rise in costs compared to immediate total mesorectal excision. There also appears to be no evident compromise in oncological outcome. Repeated response assessment in patients with a near complete clinical response after neoadjuvant chemoradiotherapy is a useful approach to identify more patients who can benefit from a watch-and-wait strategy.

CIRUGA DE TME RETRASADA EN UNA ESTRATEGIA DE WATCH AND WAIT DESPUS DE LA QUIMIORRADIOTERAPIA NEOADYUVANTE PARA CNCER DE RECTO UN ANLISIS DE COSTOS HOSPITALARIOS, Y DE RESULTADOS QUIRRGICOS Y ONCOLGICOS: ANTECEDENTES: Una estrategia de Watch and Wait para pacientes con cáncer de recto con una respuesta clínica completa después de quimiorradioterapia neoadyuvante es una alternativa valiosa en vez de resección rectal. Sin embargo, hay pacientes que tendrán tumor residual o un recrecimiento durante el Watch and Wait .OBJETIVO: El objetivo fue investigar la seguridad y los costos para los pacientes que se sometieron a una cirugía diferida después de la quimiorradioterapia neoadyuvante.DISEÑO: Este es un estudio de cohorte retrospectivo con datos recolectados prospectivamente.AJUSTE: El estudio se llevó a cabo en un gran hospital universitario.PACIENTES: Entre enero de 2015 y mayo de 2020, se atendieron 622 nuevos pacientes con cáncer de recto, de los cuales 200 recibieron quimiorradioterapia neoadyuvante. Se incluyeron 94 pacientes, de los cuales 65 se sometieron a cirugía inmediata y 29 pacientes requirieron cirugía diferida después de un enfoque inicial de observación y espera.PRINCIPALES MEDIDAS DE RESULTADO: se incluyeron la tasa de morbilidad posoperatoria a 30 días, los costos hospitalarios y las sobrevidas general y libre de enfermedad a dos años.RESULTADOS: No hubo diferencia en la duración de la estancia (9 vs 8, p = 0,83), reingresos (27,6% vs 10,0%, p = 0,10), reintervenciones quirúrgicas (15,0% vs 3,4%, p = 0,16) y tasa libre de estoma (52,6% vs 31,0%, p = 0,09) entre los grupos de cirugía inmediata y tardía. Los costos hospitalarios fueron similares en el grupo retrasado (11913 € frente a 13769 €, p = 0,89). Las tasas de sobrevida general a dos años (93% frente a 100%, p = 0,23) y sobrevida libre de enfermedad (78% frente a 81%, p = 0,47) fueron comparables.LIMITACIONES: Tamaño de muestra pequeño, tiempo de seguimiento y diseño retrospectivo.CONCLUSIÓN: La cirugía tardía para el recrecimiento en un programa de Watch and Wait o para la enfermedad residual persistente después de una evaluación repetida no se asocia con un riesgo mayor de morbilidad posoperatoria ni con un aumento significativo en los costos, en comparación con la escisión total de mesorrecto inmediata. Tampoco parece haber un compromiso evidente en el resultado oncológico. La evaluación repetida de la respuesta en pacientes con una respuesta clínica casi completa después de la quimiorradioterapia neoadyuvante es un enfoque útil para identificar más pacientes que pueden beneficiarse de una estrategia de Watch and Wait .
