Major hepatectomy in patients with insufficient future liver remnant (FLR) volume and impaired liver functional reserve has considerable risks for posthepatectomy liver failure (PHLF). The patient was a male in his 70s with an intrahepatic cholangiocarcinoma in left hemiliver, involving the middle hepatic vein (MHV). Although FLR volume after left hemihepatectomy was estimated to be 64.4% of the total liver volume, an indocyanine green retention rate at 15 min (ICG-R15) value was 24.2%, thus the patient underwent left portal vein embolization. The FLR volume increased to 71.3%; however, the noncongestive FLR volume was re-estimated as 45.8% after resection of the MHV, the ICG-R15 value was 29.0%, and ICG-Krem was calculated as 0.037. We performed partial rescue Associating Liver Partition and Portal vein occlusion for Staged hepatectomy (ALPPS) for left hemihepatectomy with the MHV reconstruction. On the first stage, partial liver partition was done along Rex-Cantlie's line, preserving the MHV and sacrificing the remaining branches to segment 8. The FLR volume increased to 77.4% on day 14. The ICG-R15 value was 29.6%, but ICG-Krem after MHV reconstruction was estimated to be 0.059. The second-stage operation on day 21 was left hemihepatectomy with the MHV reconstruction using the left superficial femoral vein graft. The usage of rescue partial ALPPS may contribute to preventing PHLF by introducing occlusion of the portal and/or venous branches in the left hemiliver before curative hepatectomy.

INTRODUCTION: Given that doubling time is an indicator of tumor growth, we assessed the usefulness of carcinoembryonic antigen doubling time (CEA-DT) in prognosis prediction after curative resection for locally recurrent rectal cancer. METHODS: During January 1986-December 2016, 33 patients with locally recurrent rectal cancer who underwent curative resection at our hospital were retrospectively reviewed. The primary endpoint was the 3-year recurrence-free survival (RFS) rate. The Kaplan-Meier method was used to compare RFS rates and evaluate univariate and multivariate analyses for factors associated with oncologic outcomes, including CEA-DT. CEA-DT was classified into 2 groups: the short and long CEA-DT groups. RESULTS: The 3-year overall survival and RFS rates were 62.6% and 42.4%, respectively. In multivariate analyses, CEA-DT was an independent risk factor for poor RFS. The 3-year RFS rate was significantly better in the long CEA-DT group than in the short CEA-DT group (58.8% vs. 25.0%, p = 0.0063). CONCLUSION: CEA-DT is a useful prognostic factor that can be assessed before surgery for locally recurrent rectal cancer. Long CEA-DT may indicate a favorable prognosis. Contrarily, short CEA-DT is associated with poor prognosis; therefore, further treatment intervention is necessary for patients with short CEA-DT.

INTRODUCTION: The impact of acute inflammation on cancer progression is still not well elucidated. Pancreatic head cancer is occasionally associated with acute cholangitis. C-reactive protein (CRP) is a biomarker that indicates presence of acute inflammation. METHODS: We reviewed the patients' data with pancreatic ductal adenocarcinoma (PDAC) who underwent pancreaticoduodenectomy between 2004 and 2018. RESULTS: Two hundred ninety-one patients were included. Median preoperative CRP was 0.45 mg/dL (0-18.9). Median follow-up duration was 22 months (4-152). The 1-, 3-, and 5-year overall survival (OS) rates were 76.4%, 32.2%, and 22.9%, respectively. Recurrence occurred in 168 cases (57.7%). The 1-, 3-, and 5-year disease-free survival (DFS) rates were 53.9%, 27.1%, and 21.9%, respectively. The median OS was higher in normal CRP patients (27 months) than those with elevated CRP (18 months) (log-rank 0.038). The median DFS was higher in normal CRP patients (17 months) than those with elevated CRP (9 months) (log-rank < 0.001). Predictive factors for OS included BMI, CRP, adjuvant therapy, positive lymph nodes, and microvascular invasion. Predictive factors for DFS included CRP, positive lymph nodes, and microvascular invasion. CONCLUSION: Preoperative CRP was an independent poor prognostic factor for OS and DFS of patients with resected PDAC.

INTRODUCTION: Endoscopic pneumatic pyloric balloon dilation is a treatment option for early postoperative delayed gastric tube emptying following esophageal resection. This study aimed to determine the safety and effectiveness of endoscopic balloon dilation. METHODS: Between 2015 and 2018, patients with delayed gastric emptying 8-10 days after esophageal resection with gastric tube reconstruction due to esophageal carcinoma were considered for inclusion. Inclusion criteria were ≥1 of the following: nasogastric tube production ≥500 mL/24 h, ≥300 mL gastric retention, ≥50% gastric tube dilatation on X-ray, or nasogastric tube replacement. Patients were excluded on evidence of anastomotic leakage or reintervention. Success was defined as the ability to expand intake without needing to replace the nasogastric tube. Dilation was performed using a 30-mm Rigiflex balloon. RESULTS: Fifteen patients underwent pyloric dilation, 12 according to the study protocol. Treatment was performed at a median of 12 days (IQR 9-15) postoperatively. Success was achieved in 58%. At 3 months, 8 patients progressed to exclusively oral intake. The remaining 4 patients had supplementary nightly enteral tube feeding. There were no adverse events. CONCLUSION: Endoscopic balloon dilation of the pylorus is a safe, feasible therapy for early postoperative delayed gastric emptying. With a success rate of 58%, a clinical trial is a necessary next step.

INTRODUCTION: The aim of this study was to identify preoperative risk factors for poor survival in patients with resectable pancreatic ductal adenocarcinoma (PDAC) treated with upfront surgery. METHODS: Medical records of 268 patients with resectable PDAC defined by resectability status who underwent upfront surgery were reviewed retrospectively. Multivariate analyses were performed to identify preoperative risk factors for recurrence-free survival (RFS) and overall survival (OS). Moreover, a binary logistic regression model was built to determine preoperative independent risk factors of 2- and 3-year recurrence and survival. RESULTS: Multivariate analyses identified CA19-9 (≥100 U/mL, p < 0.001) as an independent risk factor for poor RFS, and worse performance status (1 or 2, p = 0.03), platelet:lymphocyte ratio (<150, p = 0.04), and preoperative CA19-9 (≥100 U/mL, p < 0.001) as independent risk factors for poor OS. Moreover, preoperative CA19-9 (≥100 U/mL) was the only independent risk factor identified for 2- and 3-year recurrence and survival. DISCUSSION/CONCLUSION: Preoperative CA19-9 (≥100 U/mL) was the most reliable preoperative predictive factor for poor survival in resectable PDAC treated with upfront surgery. These findings warrant further clinical trials investigating efficacy of neoadjuvant therapy targeting the subset of patients with resectable PDAC who have elevated preoperative CA19-9, namely, those with high risk of poor prognosis.

INTRODUCTION: The aim of the study was to determine if the common bile duct (CBD) diameter increases physiologically with age and investigate whether gallstones lead to changes in CBD diameter. METHOD: Our study is composed of 721 patients in 2 groups: 517 asymptomatic patients and 204 gallstones patients who underwent MRCP. Their CBD diameter was measured at its widest visible portion on MRCP. Simple linear regression of the average of these measurements was used to investigate the relationship between age and CBD diameter in both populations. Subjects were further divided into 8 subgroups age-wise, respectively, and their means compared decade-wise using ANOVA. Furthermore, each subgroup mean from both populations was compared with each other using a t test. RESULTS: Among the 517 subjects, the mean CBD diameter was 5.3663 mm ± 1.43546 and correlated with age (p < 0.01), dilating at 0.07 mm/year. The mean diameter of our oldest group was 7.9 mm, resulting in a plausible upper limit of 8 mm for the asymptomatic population. The mean CBD diameter of the cholelithiasis population was 5.6738 mm ± 1.40986 and also correlated with age (p < 0.01). The mean CBD diameter of the age groups from the cholelithiasis population was larger than that from the asymptomatic population, but none were statistically significant. CONCLUSION: Although the CBD increases physiologically with age, there is no significant difference in CBD size between the general population and the cholelithiasis patients at any particular age. Gallstones do not independently dilate the CBD.

INTRODUCTION: Patients with very early-stage gastric signet ring cell carcinoma (SRC) are eligible for minimally invasive treatment, like endoscopic submucosal dissection. However, population-based data on regional lymph node metastasis (LNM) and distant metastasis of gastric SRC are lacking. This study aimed to identify the prevalence of LNM and distant metastasis in mucosal cancer (T1a) of gastric SRC. METHODS: The Collaborative Stage Data Survey was performed by the Korean Center of Cancer Registry between 2010 and 2015 to establish collaborative stage data of the stomach, colon, rectum, rectosigmoid junction, and breast. From the survey data, information on patients with gastric SRC was extracted for analysis. Variables including age, sex, diagnosis date, primary site, tumor size, histology, American Joint Committee on Cancer staging system scores, and Surveillance, Epidemiology, and End Results summary stage were analyzed. RESULTS: A total of 1,335 (65.7%) patients had mucosal gastric SRC, and 1,189 (89.1%) patients had surgery and 134 (10%) had endoscopic treatment. Of them, 1,283 (96.1%) patients did not have regional LNM, and 52 (3.9%) patients had regional LNM and 6 (0.4%) had distant metastasis. The hazard ratios of LNM and distant metastasis were 14.98 (95% CI: 4.18-53.2) and 10.09 (95% CI: 2.30-44.17). CONCLUSIONS: Reginal LNM and distant metastasis occur very less in mucosal gastric SRC, but they are associated with an increased risk of cancer-related death. Even in early stage, surgery should be considered as a standard treatment of mucosal gastric SRC.

INTRODUCTION: We evaluated the prognostic significance of the preoperative albumin-to-globulin ratio (AGR) in patients with hepatocellular carcinoma (HCC) with various liver etiologies. METHODS: We retrospectively analyzed 157 patients with HCC between July 2010 and February 2021. The relationship between clinicopathological variables was investigated using univariate and multivariate analyses. Statistical significance was set at p < 0.05. RESULTS: The mean overall survival (OS) was 24.5 months. The 1-, 3-, and 5-year OS rates were 90.4%, 81.2%, and 68.7%, respectively. Patients were classified into 2 groups: AGR <1.16 (low-AGR group; n = 43) and AGR ≥1.16 (high-AGR group; n = 114). In univariate analysis, OS was significantly reduced in patients with a low AGR (AGR <1.16), an alpha-fetoprotein level ≥25 ng/mL, a tumor size ≥3.5 cm, microvascular invasion, and poor tumor differentiation. In multivariate analysis, a low AGR (hazard ratio [95% confidence interval]) (2.394 [1.092-5.213]; p = 0.030) and microvascular invasion (2.268 [1.019-5.169]; p = 0.045) were independent predictors of OS. DISCUSSION/CONCLUSION: A low AGR was significantly associated with poor OS in patients with HCC, regardless of liver etiology. This may assist in treatment stratification and better management of patients with HCC.

INTRODUCTION: Laparoscopic paraesophageal hernia repair is an effective treatment for symptomatic paraesophageal hernias. To reduce recurrence rates, the use of prosthetics for the crural repair has been suggested. Mesh-related complications are rare but known to be disastrous. To address another form of crural repair, polypropylene strips are suggested. This study aimed to assess peri- and postoperative complications of reinforcement of cruroplasty with polypropylene strips. METHODS: From 2013 to 2020, patients with a primary or recurrent type 2, 3, or 4 paraesophageal hernia that underwent cruroplasty with polypropylene strips were retrospectively reviewed. Intra- and postoperative complications were graded according to the Clavien-Dindo classification. The incidence of symptomatic recurrent hiatal hernia (CT or endoscopy proven) and hospital stay were assessed. RESULTS: One hundred fifty-eight patients were included. Mean age was 65 years (standard deviation 10.4), and 119 patients were female (75.3%). Almost 50% of surgeries took place between 2018 and 2020. Median follow-up was 7 months (interquartile range 17.5). Mean operation time in the primary hernia group was 159 min (standard deviation 39.0), and length of stay was 4.4 days. In 3/158 patients (2.0%), intraoperative complications occurred. Two patients developed a grade 4 and seven patients a grade 3 postoperative complication. No mortality was recorded. Twelve recurrences (8.2%) were detected in the primary hernia group and one (9.1%) in the recurrent hernia group. CONCLUSION: There were no mesh-related complications seen and symptomatic recurrence rate was low, but longer follow-up is needed.

INTRODUCTION: Uncertainty exists about a possible survival benefit of primary tumor resection (PTR) in synchronous metastatic colon cancer (mCC). Since sidedness of the primary tumor is regarded as an important prognostic factor, our objective was to study the interaction between PTR and sidedness in synchronous mCC. METHODS: In this retrospective study, we used data from 2 first-line phase 3 randomized controlled trials (RCTs). A mixed Cox regression model was used to study the multiplicative interaction between PTR and sidedness. We adjusted for age, treatment arm, WHO performance status, number of affected organs by metastases, serum lactate dehydrogenase, and year of enrollment. RESULTS: We found that PTR is associated with better survival in both right-sided (hazard ratio [HR] 0.59 [95% confidence interval 0.42-0.8 2]) and left-sided mCC (HR 0.70 [95% confidence interval 0.52-0.93]). The interaction between PTR and sidedness was not significant (p = 0.45). CONCLUSION: Our data suggest that the prognostic value of PTR is independent of sidedness. Validation of these results will be performed in ongoing RCTs.

INTRODUCTION: With growing interest in the watch-and-wait strategy, the benefits of avoiding surgery and its complications must be weighed against possible recurrence and need for salvage surgery. However, the relationship between pathologic complete response (pCR) and postoperative complications has not been well established. METHODS: This is a retrospective study using the National Surgical Quality Improvement Program Proctectomy and Colectomy Procedure-Targeted databases from 2016 to 2018. The association between pCR and major complications, sepsis, anastomotic leak or organ space infection, return to the operating room, or septic shock was analyzed. RESULTS: A total of 3,878 rectal cancer patients who received chemotherapy or radiation therapy within 90 days of surgery were included in this study. The pCR rate was 12.8%. There was no statistically significant association between pCR and major complications (adjusted odds ratio (OR) = 0.48, p = 0.12) after risk adjustment. Those with pCR had no statistically significant association with anastomotic leak or organ space infection, return to the operating room, or septic shock but had significantly lower odds of sepsis (adjusted OR = 0.42, p = 0.03). CONCLUSIONS: It is reassuring that pCR is not associated with postoperative complications and that those with pCR are less likely to have postoperative sepsis after risk adjustment since postoperative sepsis after rectal surgery has been associated with poorer oncologic outcomes.

OBJECTIVES: The aim of the study was to evaluate the current status of gastric cancer surgery worldwide and update the changes compared to a previous survey in 2014. METHODS: A cross-sectional survey was sent to surgical members of the International Gastric Cancer Association, pilot centers of the World Organization for Specialized Studies on Diseases of the Esophagus, and the Australian and New Zealand Gastric and Oesophageal Surgeons Association in addition to participants of the 2019 International Gastric Cancer and European Society for Diseases of the Esophagus congresses. Topics addressed included hospital volume, staging, perioperative treatment, surgical approach, anastomotic techniques, lymphadenectomy, and palliative management. RESULTS: Between June 2019 and January 2020, 165 respondents from 44 countries completed the survey. In total, 80% worked in a hospital performing >20 gastrectomies annually. Staging laparoscopy and 18F-fluorodeoxyglucose positron emission tomography with computed tomography were preferred by 68 and 26% for advanced cancer, and 90% offered perioperative chemo(radio)therapy to patients. For early cancer, a minimally invasive surgical approach was preferred by 65% for distal and by 50% for total gastrectomy. For advanced cancer, this was preferred by 39% for distal and by 33% for total gastrectomy. And 84% favored a stapled anastomosis, and 14% created a jejunal pouch as reconstruction during total gastrectomy. A D2 lymphadenectomy was preferred for distal as well as for total gastrectomy, in both early (62 and 71%) and advanced (84 and 89%) cancer. CONCLUSION: This international survey demonstrates that perioperative chemotherapy and a D2 lymphadenectomy have now become the preferred treatment for gastric cancer. A minimally invasive surgical approach has gained popularity.

BACKGROUND: The first COVID-19 pandemic wave hit most of the health-care systems worldwide. The present survey aimed to provide a European overview on the COVID-19 impact on surgical oncology. METHODS: This anonymous online survey was accessible from April 24 to May 11, 2020, for surgeons (n = 298) who were contacted by the surgical society European Digestive Surgery. The survey was completed by 88 surgeons (29.2%) from 69 different departments. The responses per department were evaluated. RESULTS: Of the departments, 88.4% (n = 61/69) reported a lower volume of patients in the outpatient clinic; 69.1% (n = 47/68) and 75.0% (n = 51/68) reported a reduction in hospital bed and the operating room capacity, respectively. As a result, the participants reported an average reduction of 29.3% for all types of oncological resections surveyed in this questionnaire. The strongest reduction was observed for oncological resections of hepato-pancreatico-biliary (HPB) cancers. Of the interviewed surgeons, 68.7% (n = 46/67) agreed that survival outcomes will be negatively impacted by the pandemic. CONCLUSION: The first COVID-19 pandemic wave had a significant impact on surgical oncology in Europe. The surveyed surgeons expect an increase in the number of unresectable cancers as well as poorer survival outcomes due to cancellations of follow-ups and postponements of surgeries.

BACKGROUND: Systemic inflammatory response is involved in natural progression of cancers by different pathways. Albumin-globulin ratio (AGR) has been reported to have impact on prognosis in various solid tumors. OBJECTIVE: To study the significance of AGR on perioperative and long-term outcomes in patients undergoing PD. METHODS: This is a post hoc analysis of the pancreatic surgery database from January 2012 to March 2017. Cutoff value for AGR was calculated by using the receiver operating curve, and the study cohort was divided into group I (AGR ≥1) and group II (AGR <1). Two groups were compared for perioperative and long-term survival outcomes. RESULTS: Two groups were comparable with respect to clinicodemographic variables. Groups I and II had similar perioperative outcomes (p > 0.05) like median hospital stay (14 vs. 15 days), clinically relevant postoperative pancreatic fistula (16.6 vs. 15.7%), hemorrhage (3.1 vs. 2.6%), bile leak (1.4 vs. 0.65%), overall morbidity (30.1 vs. 28.9%), and postoperative mortality (2.7 vs. 3.9%). With a median follow-up of 3 years, median survival, overall survival, and disease-free survival were similar in both groups. CONCLUSION: AGR at the cutoff value of ≥1 was not associated with adverse perioperative and long-term oncological outcomes after PD.

BACKGROUND: The management of the pancreas in patients with duodenal trauma or duodenal tumors remains a controversial issue. Pancreas-preserving total duodenectomy (PPTD) requires a meticulous surgical technique. The most common indication is familial duodenal adenomatous polyposis (FAP). The aims of this study are to carry out a systematic review of the literature on the indications for PPTD and to highlight the risks and benefits compared with other more aggressive procedures. SUMMARY: A systematic literature review was performed following PRISMA recommendations of studies published in PubMed, Embase, and Cochrane library until May 2019. Thirty articles describing 211 patients were chosen. The mean age was 48 years. The surgical indication in 75% of patients was FAP. The mean operating time was 329 min and mean intraoperative bleeding 412 mL. Postoperative morbidity rate was 49.7% (76% Clavien-Dindo <IIIa), and mortality rate was 1.4%. The mean hospital stay was 22 days. Overall survival at 1-3-5 years was >97.8%. Key Messages: PPTD is indicated for patients with benign and premalignant duodenal lesions without involvement of the pancreatic head. It is a feasible procedure offering an alternative to other more aggressive procedures in selected patients. Mortality is below 1.5%.

INTRODUCTION: After noncurative endoscopic submucosal dissection (ESD) of superficial esophageal squamous cell carcinoma (SESCC), additional esophagectomy is generally recommended. However, considering its high mortality and morbidity, it is uncertain if additional surgery improves the clinical outcomes. This study aimed to compare the clinical outcomes between patients who were observed without additional treatment and those who underwent radical esophagectomy. METHODS: A total of 52 patients with SESCC who underwent complete but noncurative ESD from January 2008 to December 2016 at the Samsung Medical Center and Asan Medical Center in Korea were retrospectively analyzed. Clinicopathologic characteristics and oncologic outcomes were compared between the observation group (n = 23) and the additional surgery group (n = 29). RESULTS: During a mean follow-up of 34.4 and 41.7 months, respectively, the rates of death (observation vs. surgery, 17.4 vs. 10.3%; p = 0.686), recurrence (observation vs. surgery, 13 vs. 17.2%; p = 1.000), and disease-specific death (observation vs. surgery, 4.3 vs. 6.9%; p = 1.000) did not significantly differ between the 2 groups. The 3-year overall survival was 86.3 and 96.4%, respectively (p = 0.776). The 3-year recurrence-free survival (observation vs. surgery, 85.0 vs. 88.7%; p = 0.960) and disease-specific survival (observation vs. surgery, 95.2 vs. 96.4%; p = 0.564) also did not significantly differ. CONCLUSIONS: The clinical outcomes of close observation of noncuratively resected SESCC are comparable to those of additional surgery, at least in the midterm. The wait-and-see strategy could be a feasible management option after noncurative ESD of SESCC in selected patients.

METHODS: This observational cohort study analyzed consecutive patients who underwent laparoscopic adrenalectomy with a lateral transperitoneal approach at a single center (2003-2020). Data and outcomes of obese (body mass index ≥30 kg/m2) and nonobese patients were compared. To analyze the association between operative time and other variables, we used simple and multivariate linear regression. RESULTS: N = 160 (90 obese/70 nonobese) patients underwent laparoscopic adrenalectomy. Cushing syndrome and pheochromocytoma were the most frequent indications. Obese patients were older (58 vs. 52 years, p < 0.001). A greater proportion of obese patients were ASA grade III + IV (71.1 vs. 48.6%, p = 0.004). Obesity was associated with a longer operative time (72.5 vs. 60 min, p < 0.001) and greater blood loss (40 vs. 20 mL, p = 0.022). There were no differences in conversion, morbidity, or hospital stay. After adjustment for confounding factors, operative time was positively correlated with BMI ≥30 kg/m2, learning curve, estimated blood loss, 2D laparoscopy, and specimen size. CONCLUSION: Lateral transperitoneal laparoscopic adrenalectomy is safe in patients with a BMI 30-35 kg/m2, so these patients also benefit from this minimally invasive surgery.

BACKGROUND: Mural thickening (MT) on computed tomography (CT) poses a diagnostic dilemma in the absence of clear reporting guidelines. The aim of this study was to analyse CT reports, identifying patients in whom gastrointestinal wall MT was observed, and to correlate these reports with subsequent endoscopic evaluation. METHODS: Patients with MT who had follow-up endoscopy were included in the study (n = 308). The cohort was subdivided into upper gastrointestinal mural thickening (UGIMT) & lower gastrointestinal mural thickening (LGIMT). RESULTS: In total, 55.71% (n = 122) of colonoscopies and 61.8% (n = 55) of gastroscopies were found to be normal. Haemoglobin (HB) level in combination with MT was a predictor of neoplasia in both arms (p = 0.04 UGIMT cohort, p < 0.001 LGIMT cohort). In addition to this, age was a significant correlative parameter in both UGIMT and LGIMT cohorts (p = 0.003, p < 0.001 respectively). Dysphagia and weight loss were associated with UGI malignancies (38 and 63% respectively) and rectal bleeding was correlative in 20% of patients with LGI malignancies. CONCLUSION: HB, advancing age, and red flag symptoms are potentially useful adjuncts to MT in predicting upper and lower gastrointestinal malignancies. We propose the adoption of a streamlined pathway to delineate patients who should undergo endoscopic investigation following CT identification of MT.

INTRODUCTION: The purpose of this study was to analyze survival outcomes after segmental bile duct resection (BDR) for mid-common bile duct cancer according to the length of the tumor-free BDR margins. METHOD: A total of 133 consecutive patients underwent BDR for mid-bile duct cancers between December 2007 and June 2017. The Cox proportional hazard model was used to verify the cutoff value of the R0 resection margin. The patients were divided into 3 groups according to resection margin status (group 1; R0 resection margin ≥5 mm; group 2, R0 resection margin <5 mm; and group 3, R1 resection margin). RESULTS: The median follow-up period of the study cohort was 24 months. A resection margin of 5 mm in length was verified to be suitable as a reliable cutoff value. The median disease-free and overall survival (OS) periods were 32 and 49 months in group 1, 13 and 20 months in group 2, and 23 and 30 months in group 3, respectively (p = 0.03 and p < 0.001). The length of the tumor-free resection margin (hazard ratio, 2.01; 95% confidence interval, 1.10-3.67; p = 0.022) was independent factor affecting OS. CONCLUSIONS: BDR for mid-bile duct cancer appears to be a feasible surgical option in selected patients with careful preoperative imaging assessment and intraoperative frozen-section diagnosis. Our results suggest achieving a BDR margin ≥5 mm to improve survival outcomes.
