- Abstract
Background: Anastomotic leak after restorative surgery for rectal cancer is a major complication and may lead to worse long-term oncological and survival outcomes., Objective: The purpose of this study was to identify risk factors associated with anastomotic leak and to assess the perioperative and long-term oncological impact of anastomotic leak in our cohort of patients with rectal cancer., Design: A retrospective analysis was performed on data from the prospectively maintained Cabrini Monash colorectal neoplasia database. Patients who had undergone rectal cancer resection and subsequently received anastomosis between November 2009 and May 2020 were included in this study. Patient and tumor characteristics, technical risk factors, and short-term and perioperative as well as long-term oncological and survival outcomes were assessed., Settings: The study was conducted in 3 tertiary hospitals., Patients: A total of 693 patients met the inclusion criteria for this study., Main Outcome Measures: Univariate analyses were performed to assess the relationship between anastomotic leak and patient and technical risk factors, as well as perioperative and long-term outcomes. Univariate and multivariate proportional HR models of overall and disease-free survival were calculated. Kaplan-Meier survival analyses assessed disease-free and overall survival., Results: Anastomotic leak rate was 3.75%. Males had an increased risk of anastomotic leak, as did patients with hypertension and ischemic heart disease. Patients who experience an anastomotic leak were more likely to require reoperation and hospital readmission and were more likely to experience an inpatient death. Disease-free and overall survival were also negatively impacted by anastomotic leaks., Limitations: This is a retrospective analysis of data from only 3 centers with the usual limitations. However, these effects have been minimized because of the high quality and completeness of the prospective data collection., Conclusions: Anastomotic leaks after restorative surgery negatively affect long-term oncological and survival outcomes for patients with rectal cancer.

Se incluyeron en este estudio pacientes que fueron sometidos a una resección del cáncer de recto y que posteriormente recibieron una anastomosis entre noviembre de 2009 y mayo de 2020. Se evaluaron las características del paciente y del tumor, los factores de riesgo relacionados a la técnica, los resultados oncológicos y de supervivencia perioperatorio, así como los resultados a corto y largo plazo.AJUSTES:El estudio se realizó en tres hospitales terciarios.PACIENTES:Un total de 693 pacientes cumplieron con los criterios de inclusión para este estudio.PRINCIPALES MEDIDAS DE RESULTADO:Se realizaron análisis univariados para evaluar la relación entre la fuga anastomótica y aquellos factores relacionados al paciente, a la técnica, así como los resultados perioperatorios y a largo plazo. Se calcularon modelos de razón de riesgo proporcional univariante y multivariante de supervivencia global y libre de enfermedad. Los análisis de supervivencia de Kaplan-Meier evaluaron la supervivencia libre de enfermedad y la supervivencia global.RESULTADOS:La tasa de fuga anastomótica fue del 3,75%. Los hombres tenían un mayor riesgo de fuga anastomótica al igual que aquellos pacientes con hipertensión y cardiopatía isquémica. Los pacientes que sufrieron una fuga anastomótica tuvieron mayores probabilidades de requerir una reintervención y reingreso hospitalario, así como también tuvieron mayores probabilidades de sufrir una muerte hospitalaria. La supervivencia libre de enfermedad y general también se vio afectada negativamente por las fugas anastomóticas.LIMITACIONES:Este es un análisis retrospectivo de datos de solo tres centros con las limitaciones habituales. Sin embargo, estos efectos han sido minimizados debido a la alta calidad y la exhaustividad de la recopilación prospectiva de datos.CONCLUSIONES:Las fugas anastomóticas después de una cirugía restauradora afectan negativamente los resultados oncológicos y de supervivencia a largo plazo para los pacientes con cáncer de recto.

- Abstract
Background: Surgery in the very elderly is a topic that has not been well studied, despite the steady rise in this population. With the rise in this population, there is now discussion on the safety of surgery in this cohort for colorectal cancer., Objective: The purpose of this study was to investigate elective and nonelective colorectal cancer surgery outcomes in patients aged ≥90 years at both private and public hospitals in Melbourne, Victoria, Australia., Design: This was a retrospective analysis of patients aged ≥90 years who were included in the prospectively maintained Cabrini Monash University Department of Surgery colorectal neoplasia database for patients entered between January 2010 and February 2015. Comorbidity, ASA score, acuity of surgery, treatment, mortality, morbidity, and survival were analyzed., Settings: This study was conducted in a tertiary referral hospital., Patients: A total of 48 patients were identified from the database. The majority of these patients were women (58.0%), ASA score III to IV (91.7%), and treated in an elective setting (79.2%). The median age was 91.8 years., Main Outcome Measures: We measured 30-day mortality, 180-day mortality, and perioperative morbidity., Results: Thirty-day mortality rate was 2.1%. The 180-day mortality rate was 10.4%. A total of 29.2% of patients had a perioperative complication. Median follow-up was 21 months (range, 13-54 months). In 180-day mortality, minimally invasive surgery was associated with a lower mortality rate vs open surgery (p = 0.043). Perioperative complications were associated with nonelective surgery (p = 0.045), open surgery procedures (p = 0.014), and higher stages of disease (p = 0.014). A total of 81.3% of patients were able to return home after surgery., Limitations: This was a retrospective study with the usual limitations; however, these have been minimized with the use of a high-quality, prospective data collection database. The median follow-up was 21 months., Conclusions: Colorectal surgery was generally safe for nonagenarians in this study. This study demonstrates that excellent outcomes can be achieved in a selected group. Additional prospective studies with larger numbers and 5-year follow-up are recommended.

- Abstract
Background: Many studies have shown significantly improved outcomes (reduced local recurrence and improved overall survival) for patients achieving a complete pathological response from neoadjuvant chemoradiotherapy., Objective: This study aimed to document the complete pathological response rate and outcomes in patients receiving preoperative long-course chemoradiotherapy stratified for the extent of T3 mesorectal invasion measured on preoperative imaging., Design: This is a retrospective study of prospectively collected data, of patients with rectal cancer in the Cabrini Monash University Department of Surgery colorectal neoplasia database, incorporating data from Cabrini Hospital and The Alfred Hospital, identifying patients entered between January 2010 and June 2014., Patients and Settings: One hundred eighteen patients with T3 rectal cancer met the selection criteria for the study; 26 achieved complete pathological response (22%)., Main Outcome Measures: Outcomes in terms of complete pathological response and oncological outcomes such as disease-free and overall survival were analyzed., Results: Patients with complete pathological response had significantly less preoperative invasion than those with no complete pathological response (p < 0.001). Depth of invasion was the only variable associated with complete pathological response (p < 0.002), and the likelihood of complete pathological response decreased by 35% for every millimeter of invasion. Complete pathological response was associated with increased disease-free survival (p = 0.018) and a lower risk of cancer progression (p = 0.046). Depth of invasion was associated with an increased risk of death after surgery; HR increased by 1.07 (95% CI, 1.00-1.15) for each 1-mm increase in invasion., Limitations: This was a retrospective study with the usual limitations, although these were minimized through the use of a clinician-driven prospective database., Conclusions: The smaller the degree of T3 invasion, the higher the chance of achieving complete pathological response (up to 35%), which is associated with improved disease-free and overall survival. A higher complete pathological response rate is observed in early T3 disease in comparison with more extensive T3 invasion.
