BACKGROUND & AIMS: A systemic inflammatory response via host-tumor interactions is a cancer hallmark that plays a pivotal role in the pathogenesis of malnutrition and sarcopenia in patients with malignancies. Hochuekkito (TJ-41) is a traditional Japanese herbal medicine that modulates inflammation in patients with various chronic inflammatory diseases. However, the clinical efficacy of TJ-41 in patients with malignancies remains unclear. METHODS: We systemically analyzed chronological changes in levels of systemic inflammatory parameters, nutrition-related parameters, and body composition status in 99 patients who received TJ-41 treatment for more than 3 months. The cohort comprised 56 patients with gastrointestinal cancer (Cancer Cohort) and 43 with other diseases (Other Disease Cohort). We also performed in vivo experiments in mice to validate the clinical findings. RESULTS: Despite no significant changes in serum albumin concentration and prognostic nutrition index, the serum C-reactive protein (CRP) concentration significantly decreased in a time-dependent manner in all patients. However, the serum CRP concentration significantly decreased during TJ-41 treatment in the Cancer Cohort but not the Other Disease Cohort. Furthermore, downregulation of CRP during TJ-41 treatment occurred only in patients with metastases. The psoas muscle index, as a muscle quantity marker, was significantly lower in the CRP-increased group compared with the CRP-decreased group during TJ-41 treatment. In vivo experiments using a Colon-26 syngeneic model showed that the plasma CRP, amyloid A, and interleukin-6 concentrations were significantly lower in the TJ-41 group than the control group. CONCLUSION: TJ-41 might be useful as part of multimodality therapy for gastrointestinal cancer, especially in patients with metastases.

Background and aims: Crohn's disease (CD)-associated intestinal cancers are characterized by their high incidence, particularly at the anorectal site in the Japanese population. Accumulating evidence revealed that younger-onset sporadic colorectal cancer may exhibit unique biological features. To the best of our knowledge, few previous articles reported clinicopathological features in patients with CD-associated anorectal cancer (CDAAC). Therefore, we aimed to clarify the relationship between the younger onset of cancer and clinicopathological characteristics and prognosis, and the efficacy of cancer surveillance in patients with CDAAC. Methods: CD patients who had been diagnosed with intestinal cancers from 1983 to 2020 were collected from 39 Japanese institutions in this study. Of 316 patients with CD-associated intestinal cancers, we analyzed 211 patients with CDAAC. We divided the patients into two groups according to the median age at cancer diagnosis (45 years old). Results: Younger-onset CDAAC (YO-CDAAC) patients were significantly more likely to have a poor outcome than those with older-onset CDAAC (OO-CDAAC) in terms of both disease-free survival (DFS) (p = 0.0014) and overall survival (OS) (p = 0.023). Multivariate analysis showed that age under 45 years old at diagnosis of cancer was one of the independent factors for poor DFS and OS (hazard ratios: 2.15, 95% confidence interval: 1.09-4.26, p = 0.028, hazard ratios: 1.95, 95% confidence interval: 1.05-3.60, p = 0.033, respectively). Patients detected via surveillance showed significantly better DFS and OS rates than symptomatic patients in YO-CDAAC (p = 0.012 and 0.0031, respectively). Conclusions: YO-CDAAC may have a poorer prognosis compared with OO-CDAAC. Surveillance could be important to improve cancer prognosis, especially in young CD patients with anorectal disease.
RÉSUMÉ
BACKGROUND: Gastric cancer (GC) is a major leading cause of cancer-related death worldwide. Systemic inflammation and the nutrition-based score are feasible prognostic markers for malignancies. Emerging evidence has also revealed the C-reactive protein-albumin-lymphocyte (CALLY) index to be a prognostic marker for several cancer types. However, its clinical significance to predict surgical and oncologic outcomes of patients with GC remains unclear. METHODS: We assessed the preoperative CALLY index in 426 patients with GC who received gastrectomy. RESULTS: A low preoperative CALLY index was significantly correlated to all well-established clinicopathologic factors for disease development, including an advanced T stage, the presence of venous invasion, lymphatic vessel invasion, lymph node metastasis, distant metastasis, and an advanced TNM stage. A low preoperative CALLY index was also an independent prognostic factor for overall survival (hazard ratio [HR], 2.64; 95 % CI, 1.66-4.2; P < .0001) and disease-free survival (HR, 1.76; 95 % CI, 1.01-3.05; P = .045). In addition, a low preoperative CALLY index was an independent predictive factor for postoperative surgical site infection (odds ratio, 2.64; 95 % CI, 1.42-4.89; P = .002). CONCLUSION: The preoperative CALLY index is valuable for perioperative and oncologic management of patients with GC.

BACKGROUND: Postoperative pancreas-related complications (PPRCs) are common after laparoscopic gastrectomy (LG) in patients with gastric cancer. We estimated the anatomical location of the pancreas on a computed tomography (CT) image and investigated its impact on the incidence of PPRCs after LG. METHODS: We retrospectively reviewed the preoperative CT images of 203 patients who underwent LG for gastric cancer between January 2010 and December 2017. From these images, we measured the gap between the upper edge of the pancreatic body and the root of the common hepatic artery. We evaluated the potential relationship between PPRCs and the gap between pancreas and common hepatic artery (GPC) status using an analysis based on the median cutoff value and assessed the impact of GPC status on PPRC incidence. We performed univariate and multivariate analyses to identify predictive factors for PPRC. RESULT: Postoperative pancreas-related complications occurred in 11 patients (5.4%). The median of the optimal cutoff GPC value for predicting PPRC was 0 mm; therefore, we classified the GPC status into two groups: GPC plus group and GPC minus group. Univariate analysis revealed that sex (male), C-reactive protein (CRP) > .07 mg/dl, GPC plus, and visceral fat area (VFA) > 99 cm2 were associated with the development of PPRC. Multivariate analysis identified only GPC plus as independent predictor of PPRC (hazard ratio: 4.60 [95% confidence interval 1.11-31.15], P = .034). CONCLUSION: The GPC is a simple and reliable predictor of PPRC after LG. Surgeons should evaluate GPC status on preoperative CT images before proceeding with laparoscopic gastric cancer surgery.

PURPOSE: The C-reactive protein-albumin-lymphocyte (CALLY) index is a novel inflammatory nutritional biomarker. This study aimed to investigate the potential clinical significance and oncological prognostic role of the preoperative CALLY index in patients with esophageal cancer. METHODS: We analyzed the preoperative CALLY index in 146 patients with esophageal cancer. The CALLY index and clinicopathological variables were analyzed by the Mann-Whitney U test, and associations between the CALLY index and survival outcomes were analyzed by Kaplan-Meier analysis and log-rank tests. Univariate and multivariate analyses of prognostic variables were conducted using Cox proportional hazards regression. RESULTS: A lower preoperative CALLY index was significantly correlated with patient age, advanced T stage, presence of lymph node metastasis, neoadjuvant therapy, lymphatic invasion, and advanced stage classification. The preoperative CALLY index decreased significantly in a stage-dependent manner. Patients with esophageal cancer with a low CALLY index had poorer overall survival, disease-free survival than those with a high CALLY index. Multivariate analysis showed that a low CALLY index was an independent prognostic factor for overall survival, disease-free survival and an independent predictor of postoperative surgical site infection. CONCLUSIONS: Preoperative CALLY index is a useful marker to guide the perioperative and postoperative management of patients with esophageal cancer.

BACKGROUND AND AIM: Colitis-associated intestinal cancer (CAC) can develop in patients with inflammatory bowel disease; however, the malignant grade of CAC may differ from that of sporadic colorectal cancer (CRC). Therefore, we compared histological findings distinct from cancer stage between CAC and sporadic CRC to evaluate the features of CAC. METHODS: We reviewed the clinical and histological data collected from a nationwide database in Japan between 1983 and 2020. Patient characteristics were compared to distinguish ulcerative colitis (UC), Crohn's disease (CD), and sporadic CRC. Comparisons were performed by using all collected data and propensity score-matched data. RESULTS: A total of 1077 patients with UC-CAC, 297 with CD-CAC, and 136 927 with sporadic CRC were included. Although the prevalence of well or moderately differentiated adenocarcinoma (Tub1 and Tub2) decreased according to tumor progression for all diseases (P < 0.01), the prevalence of other histological findings, including signet ring cell carcinoma, mucinous carcinoma, poorly differentiated adenocarcinoma, or squamous cell carcinoma, was significantly higher in CAC than in sporadic CRC. Based on propensity score-matched data for 982 patients with UC and 268 with CD, the prevalence of histological findings other than Tub1 and Tub2 was also significantly higher in those with CAC. At pT4, mucinous carcinoma occurred at a significantly higher rate in patients with CD (45/86 [52.3%]) than in those with sporadic CRC (13/88 [14.8%]) (P < 0.01). CONCLUSION: CAC, including early-stage CAC, has a higher malignant grade than sporadic CRC, and this difference increases in significance with tumor progression.

Aortoesophageal fistula (AEF) is a rare but life-threatening pathology. We report a case of a primary AEF that was successfully managed with temporary thoracic endovascular aortic repair (TEVAR) and esophagectomy with video-assisted thoracoscopic surgery. A 73-year-old man was transferred to the emergency department with a complaint of hematemesis. A computed tomography scan identified an AEF due to aortic aneurysm. We placed a stent using TEVAR for the purpose of hemodynamic stasis, and the operation was performed 23 h after admission. Right video-assisted thoracoscopic esophagectomy (VATS-E) was chosen, and a cervical esophagostomy and a feeding gastrostomy tube was constructed. Infection had been effectively controlled postoperatively. Four months after the first operation, we performed esophageal reconstruction. At the 70-month follow-up examination, the patient had no signs of mediastinitis. VATS-E immediately after hemostabilization by TEVAR is useful management for primary AEF.

PURPOSE: To determine the methylation level of the miR-124 promoter in non-neoplastic rectal mucosa of patients with pediatric-onset ulcerative colitis (UC) to predict UC-associated colorectal cancer (UC-CRC). METHODS: Between 2005 and 2017, non-neoplastic rectal tissue specimens were collected from 86 patients with UC, including 13 patients with UC-CRC; cancer tissues were obtained from the latter group. The methylation status of the miR-124 promoter was quantified using bisulfite pyrosequencing and compared between pediatric- and adult-onset UC patients. RESULTS: Patients with pediatric-onset UC experienced a significantly shorter disease duration than those with adult-onset UC. The levels of miR-124 promoter methylation in non-neoplastic rectal mucosa were positively correlated with the age at the diagnosis and duration of UC. The rate of increase in miR-124 methylation was accelerated in patients with pediatric-onset UC compared to those with adult-onset UC. Furthermore, the miR-124 methylation levels in non-neoplastic rectal mucosa were significantly higher in patients with UC-CRC than in those with UC alone (P = 0.02). A receiver operating characteristic analysis revealed that miR-124 methylation in non-neoplastic tissue discriminated between patients with pediatric-onset UC with or without CRC. CONCLUSION: miR-124 methylation in non-neoplastic rectal mucosa may be a useful biomarker for identifying patients with pediatric-onset UC who face the highest risk of developing UC-CRC.

INTRODUCTION: The inflammatory burden index (IBI) serves as a prognostic marker for several cancers. Here, we evaluated the predictive value of preoperative IBI associated with the surgical and oncological outcomes of patients with esophageal cancer (EC). METHODS: The IBI was formulated as C-reactive protein × neutrophil/lymphocyte. We retrospectively analyzed preoperative IBI of 147 EC patients receiving esophagectomy between 2008 and 2018. Cox proportional hazards models and multivariable logistic regression were employed to identify independent risk factors of surgical site infection and prognosis. RESULTS: Increased preoperative IBI significantly correlated with higher tumor stage. Patients with high IBI experienced shorter overall survival (p = 0.0002) and disease-free survival (p = 0.002) compared with those with low IBI. In the adjusted Cox proportional hazards regression models, increased IBI served as an independent prognostic factor for overall survival (hazard ratio, 3.56; 95% confidence interval, 1.79-7.34; p = 0.0003) and disease-free survival (hazard ratio, 3.03; 95% confidence interval, 1.60-5.92; p = 0.007). Multivariable analysis identified preoperative high IBI which served as an independent risk factor for overall surgical site infection (odds ratio, 2.53; 95% confidence interval, 1.00-6.38; p = 0.049). CONCLUSION: Preoperative IBI may serve as a useful predictor of prognosis and surgical site infection of patients with EC after esophagectomy.

Fusobacterium nucleatum (Fn) has been frequently detected in colorectal cancer. A high load of Fn has been associated with subtypes of colorectal cancers, located in the proximal colon, exhibiting microsatellite instability-high (MSI-H), MLH1 promoter hypermethylation, the CpG island hypermethylation phenotype-high, or BRAF mutation in some studies. Although these features characterize the sessile serrated pathway (SSP) of colon cancers, other studies have shown that Fn infection is associated with KRAS mutations mainly characteristic of non-serrated neoplasia. It is also not clear at what point the association of Fn infection with these genomic alterations is established during colorectal carcinogenesis. Here we show that MSI-H, MLH1 hypermethylation, BRAF mutation or KRAS mutations were independently associated with Fn infection in colorectal cancer. On the other hand, increasing Fn copy number in tissues was associated with increased probability to exhibit MSI-H, MLH1 hypermethylation or BRAF mutations but not KRAS mutations in colorectal cancer. We also show that Fn load was significantly less than that of colorectal cancer and no association was detected between BRAF/KRAS mutations or MLH1 hypermethylation and Fn infection in adenomas. Our combined data suggest that increasing loads of Fn during and/or after adenomacarcinoma transition might promote SSP but not KRAS-driven colorectal carcinogenesis. Alternatively, Fn preferentially colonizes colorectal cancers with SSP and KRAS mutations but can expand more in colorectal cancers with SSP. SIGNIFICANCE: The authors demonstrated that Fn is enriched in colorectal cancers exhibiting the SSP phenotype, and in colorectal cancers carrying KRAS mutations. Fn infection should be considered as a candidate risk factor specific to colorectal cancers with the SSP phenotype and with KRAS mutations.

BACKGROUND: Double inferior vena cava (DIVC) is rare and usually detected incidentally. DIVC may be associated with several anatomical variants of the retroperitoneal and pelvic veins. These variants can pose a clinical problem during colorectal surgery. We present two patients with lower rectal cancer who also had a DIVC. CASE PRESENTATION: Case 1 was a 72-year-old man with advanced lower rectal cancer (T3N0M0) who underwent robot-assisted low anterior resection after neoadjuvant therapy. A DIVC was detected on preoperative computed tomography (CT). During the operation, a presacral vein was injured while mobilizing the rectum and hemostasis could not be achieved. We converted to open surgery and packed the pelvic cavity for hemostasis. Retrospective analysis suggested the injured vein arose from an interiliac vein of the presacral pelvic venous plexus. Case 2 was a 50-year-old woman with lower rectal cancer (T3N0M0), immune thrombocytopenic purpura, and a DIVC. Although preoperative three-dimensional CT angiography showed no obvious pelvic vein abnormalities, a short course of preoperative radiotherapy was delivered to avoid lateral pelvic lymph node dissection. Chemotherapy was deferred owing to her thrombocytopenic disease. Laparoscopic abdominoperineal resection was performed meticulously to minimize bleeding and achieve rapid hemostasis. No intraoperative complications occurred. CONCLUSION: DIVC is often accompanied by venous malformations that may pose a problem when mobilizing the mesorectum from the retroperitoneum. Preoperative assessment of pelvic vessel anatomy using three-dimensional CT is essential in patients with a DIVC who undergo rectal surgery.
RÉSUMÉ
BACKGROUND AND AIMS: Many patients have endoscopic evidence of recurrent Crohn's disease [CD] at 1 year after intestinal resection. These lesions predict future clinical recurrence. We endoscopically evaluated postoperative anastomotic lesions in CD patients from a large cohort of postoperative CD patients. METHODS: We retrospectively enrolled CD patients who underwent surgical resection between 2008 and 2013 at 19 inflammatory bowel disease [IBD]-specialist institutions. The initial analyses included patients who underwent ileocolonoscopy ~1 year after intestinal resection. Follow-up analyses assessed any changes in the endoscopic findings over time. We evaluated the postoperative endoscopic findings, which were classified into four categories [no lesion, mild, intermediate, severe] at the sites of the anastomotic line and peri-anastomosis. RESULTS: In total, 267 CD patients underwent postoperative ileocolonoscopy. Postoperative anastomotic lesions were widely detected in index ileocolonoscopy [61.0%] and were more frequently detected in follow-up ileocolonoscopy [74.9%]. Endoscopic severity also increased. Patients with intermediate or severe peri-anastomotic or anastomotic line lesions at the index ileocolonoscopy required significantly more interventions, including endoscopic dilatation or surgery, than patients with mild lesions or no lesions. CONCLUSIONS: Frequent anastomotic lesions were observed at the postoperative index ileocolonoscopy. These gradually increased for subsequent ileocolonoscopy, even in the biologic era. Regarding lesions on the anastomotic line, intermediate lesions on the anastomotic line [e.g. irregular or deep ulcers] might be considered recurrent disease, and mild lesions [e.g. linear superficial ulcers] might be considered non-recurrent disease. Prospective studies are needed to resolve this issue, including treatment enhancement.

A 37-year-old man with Crohn's disease (CD) and a history of abdominal surgery was diagnosed with anal canal cancer. Robot-assisted laparoscopic abdominoperineal resection was performed and the patient was discharged without any postoperative complications. Recently, minimally invasive surgery for CD patients has grown in popularity. However, there have been few studies of robotic surgery for CD patients with anal canal cancer. To the best of our knowledge, we present the first report of a patient with CD-associated anal canal cancer who underwent robot-assisted laparoscopic abdominoperineal resection.

A 78-year-old man presenting with a chief complaint of discomfort was found to have advanced gastric cancer invading pancreatic body, and with the metastasis of paraaortic lymph node(No. 16). After 3 courses of the S-1 plus oxaliplatin regimen, CT scan showed the disappearance of invasion to pancreatic body, and the No. 16 lymph node. Then total gastrectomy(D2+No. 19+No. 16a1+No. 16a2), Roux-en-Y reconstruction and cholecystectomy were undergoing. Histological assessment for treatment response showed Grade 1a, and we finally diagnosed gastric cancer: MU, Post, type 2, 30×20 mm, tub1>por1, ypT3, ypN1, ycM0, ypStage â ¡B. The postoperative course was uneventful, and the patient was discharged from the hospital on postoperative day 19. S-1 as adjuvant chemotherapy was performed for 12 months, and no recurrence was recognized for 5 years and 9 months after operation.

BACKGROUND: Sarcopenia consists of two dysregulation patterns of body composition, myopenia and myosteatosis. The aim of this study is to compare the preoperative status of various body composition indexes including our newly developed modified intramuscular adipose tissue content (mIMAC) to investigate these clinical values in esophageal cancer patients. METHOD: We assessed preoperative psoas muscle mass index (PMI), IMAC, and mIMAC in 150 esophageal cancer patients. RESULTS: Preoperative high IMAC and low mIMAC status were significantly associated with older age. Preoperative decreased mIMAC was significantly associated with advanced T classification and the presence of distant metastasis and low preoperative mIMAC was an independent prognostic factor for poor overall survival and disease-free survival in esophageal cancer patients. Combined assessment of preoperative mIMAC with PMI could help stratify risk for oncological outcomes. Finally, preoperative PMI and mIMAC were positively correlated with various nutritional factors in esophageal cancer patients. CONCLUSION: Combined assessment between preoperative PMI and mIMAC could stratify risk for oncological outcomes, and preoperative mIMAC might be surrogate marker for aging and nutritional status in esophageal cancer patients.

PURPOSE: To assess the severity of preoperative myopenia and myosteatosis in pediatric patients with inflammatory bowel disease (IBD) and examine their impact on postoperative complications. METHODS: The subjects of this retrospective study were 30 pediatric patients with IBD (22 with ulcerative colitis (UC) and 8 with Crohn's disease (CD)) and 67 age-matched controls. Preoperative body mass index (BMI), psoas muscle index (PMI), and intramuscular adipose tissue content were compared between the patient groups, to investigate their association with postoperative complications. RESULTS: BMI and PMI were significantly lower in the IBD patients than in the controls (p < 0.0001, p < 0.0001, respectively). CD was associated with significantly lower BMI and PMI (p = 0.01, p = 0.01, respectively) than UC. Intramuscular adipose tissue content was comparable between the IBD patients and the controls and between the UC and CD patients. There were no significant differences among the three indices in relation to the presence or absence of postoperative complications in patients with IBD. When limited to surgical site infection (SSI), only PMI was significantly lower in the patients with SSI than in those without SSI (p = 0.04). CONCLUSIONS: Although BMI and PMI were lower preoperatively in pediatric IBD patients than in controls, only myopenia seemed to affect the development of SSI.

BACKGROUND: Patients with longstanding inflammatory bowel disease are at high risk of developing intestinal cancers. In this study, we aimed to elucidate the differences between intestinal cancers associated with ulcerative colitis and Crohn's disease. METHODS: Intestinal cancers in ulcerative colitis and Crohn's disease patients treated between 1983 and 2020 at 43 Japanese institutions were retrospectively analyzed.. RESULTS: A total of 1505 intestinal cancers in 1189 ulcerative colitis and 316 Crohn's disease patients were studied. Almost all of ulcerative colitis-associated cancers (99%) were in the colon and rectum, whereas half of Crohn's disease-associated cancers (44%) were in the anus, with 11% in the small intestine. Ulcerative colitis-associated cancers were diagnosed more frequently by surveillance (67% vs. 25%, P < 0.0001) and at earlier stages (stages 0-1, 71% vs. 27%, P < 0.0001) compared with Crohn's disease-associated cancers. Colorectal cancers associated with Crohn's disease showed a significantly worse 5-year overall survival rate than those associated with ulcerative colitis (stage 2, 76% vs. 89%, P = 0.01, stage 3, 18% vs. 68%, P = 0.0009, and stage 4, 0% vs. 13%, P = 0.04). Surveillance correlated with earlier diagnoses for ulcerative colitis- and Crohn's disease-associated intestinal cancers, whereas shorter intervals between endoscopic examinations correlated with an earlier cancer diagnosis in ulcerative colitis patients but not in Crohn's disease patients. CONCLUSIONS: The clinical and oncological features of ulcerative colitis- and Crohn's disease-associated cancers were very different. Crohn's disease-associated cancers were diagnosed at more advanced stages and were detected less frequently by surveillance. Additionally, they showed a significantly poorer prognosis.

In our department, total neoadjuvant therapy(TNT), which is a combination of preoperative chemotherapy and preoperative chemoradiotherapy(nCRT), has been introduced for the purpose of local and systemic disease control for lower rectal cancer. For patients in whom a clinical complete response(cCR)was obtained by TNT, we avoid the surgery and preserve organs, and follow-up strictly under the informed consent(watch and wait). In addition, for patients with remarkably reduced primary lesions(near cCR)without lymphadenopathy after TNT, the option of omitting total mesorectal excision (TME)and performing organ preservation by local excision can be introduced. Here, we report a case in which near cCR was obtained by TNT and organ preservation was performed by local excision. A 67-year-old man with lower rectal cancer(AV 5 cm, 15 mm, type 2, cT2N0M0, cStage â )was referred to our department with a desire to preserve the anus. TNT with nCRTâCAPOX was performed, and near cCR was obtained. After that, full thickness local excision of the residual disease was performed by transanal minimally invasive surgery(TAMIS). The final pathological diagnosis was Rb, 0.7 mm, por2, ypT1a, ypPM0, ypDM0, ypRM0. No recurrence is recognized for 3 years and 10 months after the operation.
