Textbook outcome (TO) is a composite quality measurement of outcomes for evaluating surgical procedures. We investigated whether TO can be used to predict outcomes after curative resection for esophageal squamous cell carcinoma (ESCC) in elderly patients.
Methods
We retrospectively analyzed 105 patients who underwent curative esophagectomy for ESCC from 2005 to 2020. In accordance with previous reports, TO consisted of 10 parameters. The patients were divided into two groups: those who achieved TO (TO) and those who failed to achieve TO (non-TO). We evaluated the association between TO and long-term survival.
Results
TO was achieved in 28 (26%) patients. The patients in the TO group were significantly older (p = 0.02). The parameter with the lowest achievement rate was “No hospital stay ≥21 days”. The patients in non-TO group had significantly shorter overall survival than those in TO group (p = 0.03). Multivariable Cox regression analyses of overall survival revealed that lymph node metastasis (hazard ratio [HR], 3.42; 95% confidence interval [CI], 1.73–6.78; p < 0.0002) and non-TO (HR, 2.37; 95% CI, 1.05–5.65; p = 0.03) were significantly associated with poor overall survival.
Conclusion
TO can be used to predict outcomes after curative esophagectomy in elderly patients with ESCC.

The coronavirus disease 2019 (COVID-19) pandemic greatly impacted medical resources such as cancer screening, diagnosis, and treatment given to people for various diseases. We surveyed the impacts of the pandemic on the incidence of complications and mortality following pancreaticoduodenectomy for pancreatic cancer in Japan.
Methods
Data on patients who underwent pancreaticoduodenectomy for pancreatic cancer were extracted from the Japanese National Clinical Database (NCD) between 2018 and 2021. The number of the pancreaticoduodenectomy for pancreatic cancer were obtained and then the morbidity and mortality rates were evaluated using a standardized morbidity/mortality ratio (SMR), which is the ratio of the observed number of incidences to the expected number of incidences calculated by the risk calculator previously developed by the NCD.
Results
This study included 22 255 cases. The number of pancreaticoduodenectomies exhibited an increasing trend even during the COVID-19 pandemic. The mean observed incidence rates of Grade C pancreatic fistula and Clavien–Dindo grade ≥4 complications, and the 30-day mortality and surgical mortality rates were 0.8%, 1.8%, 0.8% and 0.9%, respectively. The standardized morbidity ratios did not increase during the COVID-19 pandemic. The standardized mortality ratios remained within the range of variations observed before the COVID-19 pandemic.
Conclusion
The increasing trend in the number of pancreaticoduodenectomies and favorable short-term outcomes even in the COVID-19 pandemic suggest the medical care for pancreatic cancer in Japan functioned well during the pandemic.

To evaluate the potential role of serum and tissue hsa_circ_0008621 as a prognostic biomarker for CRC patients. Focused on the functional role of hsa_circ_0008621 in colorectal cancer (CRC).
Methods
Serum and tissue hsa_circ_0008621 expression were quantified by qRT-PCR in 157 CRC patients, as well as 100 serums from healthy controls. Serum and tissue hsa_circ_0008621 expression was evaluated for their prognostic role in CRC patients using Kaplan–Meier curves and Multivariate Cox proportional hazards analysis. To further characterize the biological role of hsa_circ_0008621 expression in CRC, in vitro hsa_circ_0008621 inhibition was performed and the effects on cellular growth, migration, invasion, apoptosis, and glycolysis were explored. Next, the downstream molecules for hsa_circ_0008621 were predicted.
Results
Hsa_circ_0008621 expression was significantly upregulated in CRC tissues and serums. Serum hsa_circ_0008621 levels were significantly up-regulated in advanced-staged samples. High serum hsa_circ_0008621 expression was associated with shorter overall survival and recurrence-free survival in CRC patients. Multivariate Cox regression analysis identified a high level of serum hsa_circ_0008621 expression as an independent prognostic factor with respect to overall survival and recurrence-free survival. Loss of function assays for hsa_circ_0008621 in vitro led to a significant decrease in cell proliferation, migration, invasion, and glycolysis, but an increase in cell apoptosis. Hsa_circ_0008621 can sponge miR-532-5p, which targets SLC16A3.
Conclusion
High level of serum hsa_circ_0008621 is associated with poor survival in CRC and promotes CRC progression, suggesting it to be a promising non-invasive prognostic biomarker and novel therapeutic target in CRC patients.

The use of robotic surgery has experienced rapid growth across diverse medical conditions, with a notable emphasis on gastrointestinal cancers. The advanced technologies incorporated into robotic surgery platforms have played a pivotal role in enabling the safe performance of complex procedures, including gastrectomy and pancreatectomy, through a minimally invasive approach. However, there exists a noteworthy gap in high-level evidence demonstrating that robotic surgery for gastric and pancreatic cancers has substantial benefits compared to traditional open or laparoscopic methods. The primary impediment hindering the broader implementation of robotic surgery is its cost. The escalating healthcare expenses in the United States have prompted healthcare providers and payors to explore patient-centered, value-based healthcare models and reimbursement systems that embrace cost-effectiveness. Thus, it is important to determine what defines the value of robotic surgery. It must either maintain or enhance oncological quality and improve complication rates compared to open procedures. Moreover, its true value should be apparent in patients' expedited recovery and improved quality of life. Another essential aspect of robotic surgery's value lies in minimizing or even eliminating opioid use, even after major operations, offering considerable benefits to the broader public health landscape. A quicker return to oncological therapy has the potential to improve overall oncological outcomes, while a speedier return to work not only alleviates individual financial distress but also positively impacts societal productivity. In this article, we comprehensively review and summarize the current landscape of health economics and value-based care, with a focus on robotic surgery for gastrointestinal cancers.

Serum cholinesterase (ChE) levels are considered to reflect nutritional status. Although ChE has been well documented as a prognostic factor for some cancers, no clear consensus on its use for colorectal cancer (CRC) has been reached. The aim of this study was to investigate the relationship between preoperative serum ChE and postoperative long-term prognosis in CRC patients.
Methods
A total of 1053 CRC patients who underwent curative surgery were included in this study. The correlations between the preoperative ChE value and overall survival (OS) or cancer-specific survival (CSS) were assessed. By dividing patients into two groups according to their ChE value, OS and CSS were compared between the groups.
Results
Multivariate analysis revealed that the continuous ChE value was a significant predictor of OS (hazard ratio, 0.996; 95% CI, 0.993–0.998; p = 0.002) and CSS (hazard ratio, 0.994; 95% CI, 0.991–0.998; p = 0.001), independent of other variables. The low-ChE (≤234 U/L) group had a significantly poorer prognosis than the high-ChE (>234 U/L) group for both OS (5-year OS for low ChE and high ChE: 79.8% and 93.3%, respectively; p < 0.001) and CSS (5-year CSS for low ChE and high ChE: 84.8% and 95.6%, respectively; p < 0.001).
Conclusions
Lower preoperative serum ChE levels are a predictive factor of poor prognosis for CRC patients. As serum ChE levels can be measured quickly and evaluated easily, ChE could become a useful marker for predicting the postoperative long-term outcomes of CRC patients.
血清胆碱酯酶（ChE）水平被认为可以反映营养状况。虽然 ChE 已被证实是某些癌症的预后因素之一，但对其在结直肠癌（CRC）中的应用尚未达成明确共识。本研究旨在探讨 CRC 患者术前血清胆碱酯酶与术后长期预后之间的关系。本研究共纳入了 1053 例接受根治性手术的 CRC 患者，评估了术前 ChE 值与总生存期（OS）或癌症特异性生存期（CSS）之间的相关性。多变量分析显示，连续 ChE 值是 OS（危险比，0.996；95% CI，0.993-0.998；p = 0.002）和 CSS（危险比，0.994；95% CI，0.991-0.998；p = 0.001）的重要预测因子，与其他变量无关。就OS（低ChE和高ChE的5年OS分别为79.8%和93.3%；p < 0.001）和CSS（低ChE和高ChE的5年CSS分别为84.8%和95.6%；p < 0.001）而言，低ChE（≤234 U/L）组的预后明显差于高ChE（>234 U/L）组。由于血清胆碱酯酶水平可以快速测量且易于评估，因此胆碱酯酶可以成为预测 CRC 患者术后长期预后的有效指标。

Surgical resection is standard treatment for invasive intraductal papillary mucinous carcinoma (IPMC); however, impact of multidisciplinary treatment on survival including postoperative adjuvant therapy (AT), neoadjuvant therapy (NAT), and treatment for recurrent lesions is unclear. We investigated the effectiveness of multidisciplinary treatment in prolonging survival of patients with invasive IPMC.
Methods
This retrospective multi-institutional study included 1183 patients with invasive IPMC undergoing surgery at 40 academic institutions. We analyzed the effects of AT, NAT, and treatment for recurrence on survival of patients with invasive IPMC.
Results
Completion of the planned postoperative AT for 6 months improved the overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) of patients with stage IIB and stage III resected invasive IPMC, elevated preoperative carbohydrate antigen 19–9 level, lymphovascular invasion, perineural invasion, serosal invasion, and lymph node metastasis on un-matched and matched analyses. Of the patients with borderline resectable (BR) invasive IPMC, the OS (p = 0.001), DSS (p = 0.001), and RFS (p = 0.001) of patients undergoing NAT was longer than that of those without on the matched analysis. Of the 484 invasive IPMC patients (40.9%) who developed recurrence after surgery, the OS of 365 patients who received any treatment for recurrence was longer than that of those without treatment (40.6 vs. 22.4 months, p < 0.001).
Conclusion
Postoperative AT might benefit selected patients with invasive IPMC, especially those at high risk of poor survival. NAT might improve the survivability of BR invasive IPMC. Any treatment for recurrence after surgery for invasive IPMC might improve survival.

Malnutrition, characterized by altered body composition and impaired function, is particularly prevalent among gastric cancer patients, affecting up to 60% of them. Malnutrition in these patients can manifest both before and after surgery, due to factors such as gastric outlet obstruction, cancer cachexia, and anatomical changes. Notably, total gastrectomy (TG) presents the most significant nutritional challenges. However, function-preserving gastrectomy, such as pylorus-preserving gastrectomy (PPG) and proximal gastrectomy (PG), have shown promise in improving nutritional outcomes. Effective nutritional risk screening and assessment are vital for identifying patients at risk. Nutritional support not only improves nutritional parameters but also reduces complications, enhances quality of life (QoL) and survival rates. Those unable to maintain more than 50% of the recommended intake for over 7 days are recommended for nutritional support. Common methods of nutritional support include oral nutrition supplements (ONS), enteral nutrition (EN), or parenteral nutrition (PN) depending on the patient's status. Effect of perioperative nutritional support remains controversial. Preoperative interventions including ONS and PN have shown mixed results, with selective benefits in patients with sarcopenia or hypoalbuminaemia, while impact of EN in gastric outlet obstruction patients have been positive. In contrast postoperative support appears to be consistent. Tube feeding after TG has shown improvements, and ONS have been effective in reducing weight loss and improving nutritional biomarkers. PN was also associated with benefits such as weight maintenance and QoL. This review explores the mechanisms, assessment, and clinical impact of malnutrition, emphasizing the importance of nutritional support in gastric cancer patients undergoing gastrectomy.
营养不良以身体成分改变和功能受损为特征，在胃癌患者中尤为普遍，影响比例高达 60%。由于胃出口梗阻、癌症恶病质和解剖学变化等因素，这些患者在手术前后都可能出现营养不良。值得注意的是，全胃切除术（TG）带来的营养挑战最为严峻。然而，保留功能的胃切除术，如保留幽门的胃切除术（PPG）和近端胃切除术（PG），已显示出改善营养结果的前景。有效的营养风险筛查和评估对于识别高风险患者至关重要。营养支持不仅能改善营养参数，还能减少并发症、提高生活质量（QoL）和存活率。对于那些无法在 7 天内维持建议摄入量 50%以上的患者，建议给予营养支持。常见的营养支持方法包括口服营养补充剂（ONS）、肠内营养（EN）或肠外营养（PN），具体取决于患者的状况。围手术期营养支持的效果仍存在争议。包括 ONS 和 PN 在内的术前干预效果不一，有选择性地对肌肉疏松症或低白蛋白血症患者有益，而 EN 对胃出口梗阻患者的影响则是积极的。相比之下，术后支持似乎是一致的。TG 术后的管饲显示出了改善效果，而 ONS 则有效地减少了体重下降并改善了营养生物标志物。PN 也与体重维持和 QoL 等益处相关。本综述探讨了营养不良的机制、评估和临床影响，强调了营养支持对接受胃切除术的胃癌患者的重要性。

We conducted a multicenter study on classical laparoscopic and endoscopic cooperative surgery (LECS) and LECS-related procedures to retrospectively clarify the safety, problems, and mid-term outcomes of these methods after their coverage by the national health insurance.
Methods
A total of 201 patients who underwent classical LECS/LECS-related procedures for gastric submucosal tumors (G-SMTs) in 21 institutions affiliated with the Laparoscopy Endoscopy Cooperative Surgery Study Group from April 2014 to March 2016 were included. Data was retrospectively obtained from the patients' charts.
Results
The most common surgical procedure was classical LECS (155 patients, 77.1%), non-exposed endoscopic wall inversion surgery (22 patients, 11.4%), a combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique (16 patients, 8%), and closed LECS (two patients, 1%). Only six (3%) patients underwent LECS with gastrostomy. The mean operative time and blood loss were 188.4 (70–462) minutes and 23.3 (0–793) g, respectively. Ten (5%) patients developed postoperative complications (Clavien–Dindo classification grade II or higher). Two patients needed reoperation due to postoperative bleeding or anastomotic leakage. All tumors were resected with negative margins. A total of 127 (63.2%) patients underwent follow-up observations for over 36 months, one of whom had a recurrence of peritoneal dissemination and one had poor oral intake.
Conclusion
Classical LECS and LECS-related procedures for G-SMTs have favorable short/mid-term outcomes.

Background
This study aimed to evaluate the efficacy of lateral lymph node dissection (LLND) for rectal cancer by comparing the local control in patients with and without pathological lateral lymph node metastasis (LLNM).
Methods
We included 189 patients with rectal cancer who underwent total mesorectal excision and LLND at 13 institutions between 2017 and 2019. Patients with and without pathological LLNM were defined as the pLLNM (+) and (−) groups, respectively. Propensity score-matching helped to balance the basic characteristics of both groups. The incidences of local recurrence (LR) and lateral lymph node recurrence (LLNR) were compared between the groups.
Results
In the entire cohort, 39 of the 189 patients had pathological LLNM. The 3-year LR and LLNR rates were 18.3% and 4.0% (p = 0.01) and 7.7% and 3.3% (p = 0.22) in the pLLNM (+) and (−) groups, respectively. After propensity score matching, the data from 62 patients were analyzed. No significant differences in LR or LLNR were observed between both groups. The 3-year LR and LLNR rates were 16.4% and 9.8% (p = 0.46) and 9.7% and 9.8% (p = 0.99) in the pLLNM (+) and (−) groups, respectively.
Conclusion
LLND would lead to comparable local control in the pLLNM (+) and (−) groups if the clinicopathological characteristics except for LLNM are similar.
