How to measure quality of surgery as a component of multimodality treatment of gastric cancer

Gastric cancer (GC) is one of the most frequent reasons for cancer-related death worldwide. The multimodal therapeutic strategies are now pragmatically tailored to each patient, especially in advanced GC. A radical but safe gastrectomy remains the cornerstone of the GC treatment. Moreover, the quality-of-life (QoL) outcome measures are now routinely utilized in order to select optimal type of gastrectomy, as well as reconstruction method. Postoperative complications are frequent, and effective diagnosis and treatment of complications is crucial to lower the mortality rates. The postoperative complications prolong hospital stay and may result in poor QoL, thus eliminating the completion of perioperative adjuvant therapy. Therefore, avoiding morbidity is not only relevant for the immediate postoperative course, but can also affect long-term oncological outcome. Measuring outcome enables surgeons to: monitor their own results; compare quality of treatment between centres; facilitate improvement both for surgery alone and combined treatment; select optimal procedure for an individual patient. Textbook oncological outcome is a composite quality measure representing the ideal hospitalization for gastrectomy, as well as stage-appropriate (perioperative) adjuvant chemotherapy. Standardized system for recording complications and adherence to multimodality treatment guidelines are crucial for achieving the ultimate goal of surgical quality-improvement that can benefit patients QoL and long-term outcomes after fast and uneventful hospitalization for gastrectomy.

Predictors of textbook outcome following oesophagogastric cancer surgery

Textbook outcome (TO) is a composite measure representing an ideal perioperative course, which has been utilized to assess the quality of care in oesophagogastric cancer (OGC) surgery. We aim to determine TO rates among OGC patients in a UK tertiary center, investigate predictors of TO attainment, and evaluate the relationship between TO and survival. A retrospective analysis of a prospectively collected departmental database between 2006 and 2021 was conducted. Patients that underwent radical OGC surgery with curative intent were included. TO attainment required margin-negative resection, adequate lymphadenectomy, uncomplicated postoperative course, and no hospital readmission. Predictors of TO were investigated using multivariable logistic regression. The association between TO and survival was evaluated using Kaplan-Meier analysis and Cox regression modeling. In sum, 667 esophageal cancer and 312 gastric cancer patients were included. TO was achieved in 35.1% of esophagectomy patients and 51.3% of gastrectomy patients. Several factors were independently associated with a low likelihood of TO attainment: T3 stage (odds ratio (OR): 0.41, 95% confidence interval (CI) [0.22-0.79], p = 0.008) and T4 stage (OR:0.26, 95% CI [0.08-0.72], p = 0.013) in the esophagectomy cohort and high BMI (OR:0.93, 95% CI [0.88-0.98], p = 0.011) in the gastrectomy cohort. TO attainment was associated with greater overall survival and recurrence-free survival in esophagectomy and gastrectomy cohorts. TO is a relevant quality metric that can be utilized to compare surgical performance between centers and investigate patients at risk of TO failure. Enhancement of preoperative care measures can improve TO rates and, subsequently, long-term survival.

A novel study, textbook outcome in adrenalectomy: retrospective observational study in an endocrine surgical unit

Textbook outcome is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. Retrospective study of all patients undergoing scheduled for adrenal tumors surgery at an endocrine surgery unit from January 2010-December 2022. The definition of Textbook Outcome were: R0 resection, no Clavien-Dindo ≥ IIIa complications, no prolonged stay (< P75), no readmissions, and no mortality in the first 30 days. The main objective was to analyze the rate of Textbook Outcome obtained. One hundred and five patients were included in the study. Textbook Outcome was achieved in 71.4%. Surgical approach (p < 0.001), Charlson scale (p = 0.031), American Society of Anesthesiologists Classification (p = 0.047) and surgical time (p < 0.001) were all significantly associated with the achievement of Textbook Outcome. The laparoscopic approach was associated as an independent factor with obtaining Textbook Outcome (OR:5.394; p = 0.016), as was surgical time (OR:0.986; p = 0.004). Textbook Outcome is a novel, useful, easy-to-interpret tool for measuring results in adrenal surgery. The laparoscopic approach is associated with a higher rate of "ideal" surgical results. The study was registered in the public accessible database clinicaltrials.gov with the ClinicalTrials.gov ID: NCT05888753.

The influence of short-term postoperative outcomes on overall survival after gastric cancer surgery

BACKGROUND

Gastrectomy with lymphadenectomy in combination with perioperative chemotherapy is the cornerstone of modern curative treatment for gastric adenocarcinoma. The primary objective of this study was to assess the influence of textbook outcome, postoperative complications, and readmission on survival in patients who underwent gastric cancer surgery.

METHODS

Consecutive patients who underwent curative and prophylactic gastric resections from 2014 to 2022 at Christchurch Hospital were identified from the hospital database. Multivariable analyses were performed to assess risk factors for each postoperative outcome. A survival analysis was performed to evaluate the influence of these outcomes on overall survival.

RESULTS

Seventy-seven patients underwent a gastric resection during the study period. Thirteen were prophylactic resections for E-cadherin gene mutations and 64 were for malignancy. The overall postoperative complication rate was 34%, with an anastomotic leak rate of 8% (n = 6). The 30-day readmission rate, 30-day mortality rate and 90-day mortality rate were 17%, 1%, and 5% respectively. No sociodemographic differences were identified in each outcome. An increasing day-4 CRP trajectory was observed in patients with an anastomotic leak. Postoperative complications and nodal disease were independent prognostic factors for reduced survival.

CONCLUSIONS

Textbook outcome, postoperative complications, and readmission are validated quality performance indicators of gastric cancer surgery. Postoperative complications are associated with poor overall survival independent of severity or type. The underlying mechanisms of this influence remain elusive. The aggressive biology of gastric cancer, combined with the surgical morbidity and its negative influence on survival, highlights the importance of ongoing quality improvement.

Textbook Oncological Outcome in European GASTRODATA

OBJECTIVE

To assess the rate of textbook outcome (TO) and textbook oncological outcome (TOO) in the European population based on the GASTRODATA registry.

BACKGROUND

TO is a composite parameter assessing surgical quality and strongly correlates with improved overall survival. Following the standard of treatment for locally advanced gastric cancer, TOO was proposed as a quality and optimal multimodal treatment parameter.

METHODS

TO was achieved when all the following criteria were met: no intraoperative complications, radical resection according to the surgeon, pR0 resection, retrieval of at least 15 lymph nodes, no severe postoperative complications, no reintervention, no admission to the intensive care unit, no prolonged length of stay, no postoperative mortality and no hospital readmission. TOO was defined as TO with the addition of perioperative chemotherapy compliance.

RESULTS

Of the 2558 patients, 1700 were included in the analysis. TO was achieved in 1164 (68.5%) patients. The use of neoadjuvant chemotherapy [odds ratio (OR) = 1.33, 95% CI: 1.04-1.70] and D2 or D2+ lymphadenectomy (OR = 1.55, 95% CI: 1.15-2.10) had a positive impact on TO achievement. Older age (OR = 0.73, 95% CI: 0.54-0.94), pT3/4 (OR = 0.79, 95% CI: 0.63-0.99), ASA 3/4 (OR = 0.68, 95% CI: 0.54-0.86) and total gastrectomy (OR = 0.56, 95% CI: 0.45-0.70), had a negative impact on TO achievement. TOO was achieved in 388 (22.8%) patients. Older age (OR = 0.37, 95% CI: 0.27-0.53), pT3 or pT4 (OR = 0.52, 95% CI: 0.39-0.69), and ASA 3 or 4 (OR = 0.58, 95% CI: 0.43-0.79) had a negative impact on TOO achievement.

CONCLUSIONS

Despite successively improved surgical outcomes, stage-appropriate chemotherapy in adherence to the current guidelines for multimodal treatment of gastric cancer remains poor. Further implementation of oncologic quality metrics should include greater emphasis on perioperative chemotherapy and adequate lymphadenectomy.
