ABSTRACT
PURPOSE: A notable advantage of laparoscopic colorectal surgery is that only a small incision at the extraction site is necessary, which is considered to be cosmetically beneficial. Meanwhile, the optimal extraction site for the resected specimen in laparoscopic colectomy is controversial in terms of cosmetic benefit. This randomized controlled trial compares midline and off-midline extraction sites in laparoscopic colectomy in patients with colon cancer, with consideration of cosmetic benefits as the primary endpoint. METHODS: Included were patients that underwent elective laparoscopic colectomy at WMUH between October 2014 and February 2017. Patients were randomly assigned to either midline incision group or off-midline incision group. Prospectively collected data included cosmetic results (patients and observer assessment scale) and complications including incidence of incisional hernia, SSI, and pain. This trial was registered with UMIN Clinical Trials (UMIN000028943). RESULTS: Finally, 98 patients with colorectal cancer were analyzed. No significant differences were found between the two groups in patient and observer assessment scales of cosmetic results (midline 8 ± 1.1 vs off-midline 11 ± 5.9 p = 0.16, midline 13.5 ± 6.6 vs off-midline 15 ± 11 p = 0.58, respectively) or in postoperative pain. However, incisional hernia occurred in four cases in the midline group (8%), which was significantly higher than that in the off-midline group (no cases, 0%). CONCLUSION: There was no significant difference in terms of cosmetic benefit, the primary endpoint, between the two groups. In this study, only the extraction site location was compared; future studies will examine differences depending on the incisional direction, including the incidence of incisional hernia.

BACKGROUND: Accurate tumor stage diagnosis during laparoscopic surgery remains difficult. We clarify the impact of new diagnostic strategy using narrow-band imaging (NBI) during laparoscopic surgery for colorectal cancer compared with other strategies. METHODS: We defined angiogenesis (Ag) and fibrosis (Fib) grades using NBI laparoscopy (lap-NBI), and assessed the clinicopathological features associated with these grades for 67 patients with colorectal cancer who underwent surgery. We assessed vessel density and gray scale with computer software. RESULTS: NBI-Ag-grade and NBI-Fib-grade of the serosal surface of cancer lesions and peritoneal nodules correlated with vessel density and gray scale of those assessed by Image J computer software. NBI-Fib-grades of liver nodules also correlated with gray scale. NBI-Ag- grade and Fib-grade of the serosal surface of cancer lesions correlated with pathological depth of invasion. These NBI grades of pathological metastatic peritoneal nodules were higher than those of pathologically benign peritoneal nodules. NBI- Fib grades of pathological metastatic liver nodules were higher than those of pathologically benign liver nodules. In multivariate analysis, lap-NBI was associated with different diagnosis for T3, T4 and non-T3, and non-T4. Moreover, lap-NBI was associated with different diagnosis for T4 and non-T4. Predictive value for T4 by lap-NBI showed high sensitivity (85%) specificity (87%), positive predictive value (74%), negative predictive value (93%), and overall accuracy (87%). Sensitivity and overall accuracy of lap-NBI was superior to that of other diagnostic modalities. CONCLUSION: We clarified the usefulness of the new diagnostic strategy using lap-NBI during laparoscopic surgery for colorectal cancer in comparison with other strategies.

PURPOSE: Risks for postoperative small bowel obstruction have been demonstrated in several reports, most of which indicated male sex was a risk factor, but with the reason remaining unknown. We tested the hypothesis that it could be because males have more visceral fat than females. This prospective observational study aims to examine risks of early postoperative small bowel obstruction (EPSBO) after colorectal cancer surgery and the association between visceral to subcutaneous fat area ratio (V/S ratio) and EPSBO. METHODS: Four hundred and seventy-four patients who underwent colectomy for colorectal cancer in our hospital were enrolled in this study. The influence of several factors including V/S ratio on the development of EPSBO was analyzed. RESULTS: Thirty-one of the 474 patients (6.5%) developed EPSBO. EPSBO occurred more frequently in males (p = 0.03) and cases who developed postoperative anastomotic leakage (p < 0.001) or wound infection (p = 0.02). Higher V/S ratio was strongly related to male sex (p < 0.001). Multivariate analysis revealed higher V/S ratio (OR 2.25; p = 0.049) and anastomotic leakage (OR 5.86; p < 0.001) were independent risk factors for EPSBO. CONCLUSION: Higher V/S ratio was significantly related to EPSBO, suggesting that one of the reasons EPSBO was more likely to occur in males because they have more visceral fat than females. Preoperative identification of this risk factor could help us watch out for this potential complication.

OBJECTIVES: The increasingly elderly worldwide population has affected the incidence of colorectal cancer. Establishment of reliable assessment of frailty and proposals for multi-disciplinary interventions are urgently required in oncology practices. Kihon Checklist (KCL) was published by the Japanese Ministry of Health, Labor and Welfare originally to identify individuals ≥ 65 years old at probable risk for requiring care or social support. We investigate the validity of KCL for frailty assessment to predict postoperative complication in older patients with colorectal cancer. METHODS: Consecutive colorectal cancer patients aged ≥ 65 (n = 500) were prospectively examined between May 2017 and December 2018. Preoperative frailty assessment was conducted by the G8 questionnaire and KCL. The main outcome measures were correlation between frailty, other clinical variables, and postoperative complications within 30 days after elective surgery. RESULTS: Of the 500 patients, 278 (55.6%) and 164 (32.8%) patients were classified as 'frail' by G8 and KCL, respectively. Overall complications counted among 97 patients (19.4%), and they were significantly associated with KCL ≥ 8-frail (46/164, p = 0.001), as opposed to G8 ≤ 14-frail (56/278, p = 0.531). Multivariate analysis showed that KCL ≥ 8 (hazard ratio 1.88, 95% confidence interval 1.16-3.04, p = 0.011) was an independent risk factor for these complications. CONCLUSIONS: KCL assessment can identify frail older patients likely to suffer from postoperative complications after colorectal cancer surgery. Preoperative screening of frailty, particularly by KCL, would help older patients prevent their worse outcomes in colorectal cancer. TRIAL REGISTRATION: UMIN000026689.

BACKGROUND: Cancer peptide vaccines show only marginal effects against cancers. Immune checkpoint inhibitors (ICIs) show significant curative effects in certain types of cancers, but the response rate is still limited. In this study, we aim to improve cancer peptide vaccination by targeting Ag peptides selectively to a dendritic cell (DC) subset, XCR1-expressing DCs (XCR1+ DCs), with high ability to support CD8+ T-cell responses. METHODS: We have generated a fusion protein, consisting of an Ag peptide presented with MHC class I, and an XCR1 ligand, XCL1, and examined its effects on antitumour immunity in mice. RESULTS: The fusion protein was delivered to XCR1+ DCs in an XCR1-dependent manner. Immunisation with the fusion protein plus an immune adjuvant, polyinosinic:polycytidylic acids (poly(I:C)), more potently induced Ag-specific CD8+ T-cell responses through XCR1 than the Ag peptide plus poly(I:C) or the Ag protein plus poly(I:C). The fusion protein plus poly(I:C) inhibited the tumour growth efficiently in the prophylactic and therapeutic tumour models. Furthermore, the fusion protein plus poly(I:C) showed suppressive effects on tumour growth in synergy with anti-PD-1 Ab. CONCLUSIONS: Cancer Ag targeting to XCR1+ DCs should be a promising procedure as a combination anticancer therapy with immune checkpoint blockade.

BACKGROUND: Synchronous colorectal peritoneal carcinomatosis (SCPC) is not a rare entity, and the prognosis is extremely poor compared to other metastatic sites such as the liver and lung. Therefore, optimal treatment based on tumor characteristics is needed. Recently, the tumor sidedness of colorectal cancer has been reported as one of the prognostic factors and also as a key factor for the treatment strategy. The purpose of this study was to assess the clinical impact of tumor sidedness in patients with SCPC. METHODS: A total of 189 cases of SCPC were identified in a retrospective database at Wakayama Medical University Hospital (WMUH) between 1998 and 2014, and were analyzed with a special focus on tumor location. RESULTS: In multivariate analysis, a right-sided location (p = 0.02) and the presence of liver metastases (p < 0.001) were found to be the worst prognostic factors. The median survival time (MST) with right-sided and with left-sided SCPC was 10 and 16 months, respectively. The right-sided SCPC group included more aged patients (p = 0.045) and fewer patients who received postoperative chemotherapy (p = 0.034). When we focused on patients with macroscopically complete resection (n = 39), the MST and disease-free survival in the right-sided SCPC group was significantly shorter than in the left-sided SCPC group (p = 0.030 and p = 0.043, respectively). The MST of the right-sided and the left-sided SCPC patients among the completely resected patients was 24 and 73 months, respectively. CONCLUSION: Tumor sidedness may be a potent prognostic indicator for patients with SCPC. The survival time with right-sided SCPC is dramatically reduced compared to that with left-sided SCPC, especially among completely resected cases. We should change the treatment strategy according to the location of SCPC.

PURPOSE: Creation of defunctioning loop ileostomy is a standard procedure in laparoscopic lower rectal surgery. Stoma-related obstruction sometimes occurs, but its cause has not been fully analyzed. This study aims to assess stoma obstructive complications and clarify the risk factors of stoma-related obstructions. METHODS: Two hundred and thirty consecutive patients who underwent laparoscopic rectal cancer surgery with defunctioning loop ileostomy between April 2007 and December 2017 were recruited, numbering 230. We statistically examined the frequency and risk factor of stoma outlet obstruction. RESULTS: Postoperative stoma-related complications developed in 41 patients (17.8%) overall, and there was no 30-day mortality. Stoma outlet obstructions occurred in 16 patients (7.0%) during postoperative course. Thick subcutaneous fat at the stoma-marking site (vertical distance ≥ 20 mm) and body mass index (≥ 22.2) were significantly associated with the risk of stoma outlet obstruction in univariate analysis. Thick subcutaneous fat was a significant predictive factor of stoma outlet obstruction according to multivariate analysis (odds ratio 3.80). CONCLUSIONS: This report investigates significant predictors of stoma outlet obstruction in laparoscopic rectal cancer surgery for the first time. In laparoscopic procedure, stoma outlet obstruction should be particularly considered in obese patients who have especially thick subcutaneous fat of the abdominal wall.

Primary small bowel cancer is a rare entity; thus, it is often found in progress. Therefore, the prognosis is often poor. Because of its low frequency, there are few reports concerning the treatment for small bowel cancer; hence, it is important to examine individual cases in detail. In this study, we present a case of recurrent small bowel cancer that successfully responded to chemoradiation therapy. Case: A 48-year-old woman had anemia. Colonoscopy showed a tumor in the terminal ileum. Because of invasion in the ovaries and uterus, ileocecal resection, hysterectomy, and bilateral adnexectomy were performed. The pathological diagnosis was small bowel cancer with lymph node metastasis, and CapeOX therapy was administered as postoperative adjuvant chemotherapy. Since local recurrence was detected in the right lower quadrant 6 months after the surgery, IRIS plus BV was initiated. Radiation therapy(2Gy×25 times, total 50 Gy)was also administered within the same period(only S-1 administration during radiation). After radiation therapy, the tumor decreased significantly in size and showed CR. Currently, the patient is under observation without treatment, but she has had no recurrence for 6 years after the confirmation of recurrence(6 years and 6 months after surgery). It is extremely rare for chemoradiation therapy to be effective for recurrent small bowel cancer; we report such a case with literatures.

Tumor-derived peptides can induce antitumor cytotoxic T lymphocyte(CTL)response. However, the effects are limited. We aimed to overcome this limitation by selectively delivering antigen peptides to an XC chemokine receptor 1-expressing dendritic cell subset(XCR1+DC)that is notable for its exceptional ability to generate CTL response. To do that, we designed a vaccine(mXCL1-OVA peptide vaccine)that consisted of a murine XCR1 ligand(XCL1)and an ovalbumin(OVA)-derived MHC class I-restricted antigen. When co-injected with the immune adjuvant polyinosinic-polycytidylic acid(poly[I: C]), mXCL1-OVA peptide vaccine showed much greater antigen-specific cytotoxic T cell(CTL)response than either OVA protein plus poly(I: C)or OVA peptide plus poly(I: C). Furthermore, mXCL1-OVA peptide vaccine plus poly(I: C)showed more prominent antitumor effects against OVA-expressing melanoma(B16-OVA)than other vaccines with regard to growth inhibition. Thus, our results suggest that chemokine-directed antigen delivery to DC subsets with high CTL-inducing ability is a promising method for generating effective antitumor immunity.

PURPOSE: The International Study Group of Rectal Cancer (ISREC) has proposed a new definition of anastomotic leakage (AL) which was simply classified into three grades; however, these criteria have not been assessed well. The aims of this study are to assess the new definition and to show the clinical features of AL after an anterior resection for rectal cancer. METHODS: Fifty consecutive patients developed AL after an anterior resection for rectal cancer was retrospectively assessed. AL was defined by the ISREC criteria. RESULTS: Twenty-seven (54 %) patients with AL were diagnosed by drain contents. The postoperative day of diagnosis for AL was later in grade A versus grades B and C (p = 0.038 vs p = 0.006, respectively). Permanent stoma (PS) was significantly more frequent in patients with grade C but not grade B compared to the patients with no AL (p < 0.001 and p = 0.171, respectively). In patients without diverting stoma, there was more serious grade of AL (p < 0.001). CONCLUSIONS: Differences were observed in the postoperative day of diagnosis, the creation rate of PS, and impact on diverting stoma after AL between each grade of leakage. The new classification was easy and reasonable to evaluate AL. As a result, it should be widely used in future studies.

PURPOSE: This study demonstrated the usefulness of the post/preoperative serum carcinoembryonic antigen (CEA) ratio as a predictor of survival after surgery for stage III rectal cancer patients. METHODS: One hundred and four patients with stage III rectal cancer who underwent surgery between 1991 and 2000 were enrolled. The ratio of the postoperative serum CEA value divided by the preoperative serum CEA value was defined as post/preoperative serum CEA ratio, and the patients were separated into two groups: post/preoperative serum CEA ratio ≤ 1 (n = 86) and >1 (n = 18). RESULTS: The multivariate analyses demonstrated that the intraoperative blood loss, lack of a sphincter-saving procedure and a post/preoperative serum CEA ratio >1 were independent factors predicting a poor prognosis for the overall and disease-free survival. The overall and disease-free survival rates among patients with a high preoperative serum CEA level (>5 ng/ml) or patients with a high postoperative serum CEA (>5 ng/ml) were longer in patients with a post/preoperative serum CEA ratio ≤ 1, in comparison to those with a post/preoperative serum CEA ratio >1. Liver metastasis was observed more frequently in patients with a post/preoperative serum CEA ratio >1. CONCLUSIONS: The post/preoperative serum CEA ratio may be a predictor of the prognosis after surgery for stage III rectal cancer patients.

Tumefactive demyelinating lesions (TDL), defined as inflammatory demyelinating lesions, may develop either during treatment for multiple sclerosis and related disorders or as the first demyelinating episode without any past medical history suggesting demyelination. If the latter, it would be so delicate to diagnose as demyelination. Especially in such situations, biopsy is often necessary in addition to neuroimaging for distinction TDL with tumorous or infectious diseases. In this article, we will review about concept, epidemiology, diagnosis, and treatment of TDL.

BACKGROUND: Fireplay and arson incidents among children and adolescents have gained attention because of their potentially severe consequences and societal impacts. Understanding the underlying psychiatric characteristics of individuals engaging in fireplay or arson is crucial for early identification and targeted intervention. However, there is a lack of research conducted in clinical psychiatric populations in this context. This study compared the clinical characteristics of child and adolescent psychiatric outpatients who engaged in fireplay or arson with those without such behaviors. METHODS: A retrospective case-control study was conducted using data collected from patients who visited the Department of Child and Adolescent Psychiatry at Kohnodai Hospital, National Center for Global Health and Medicine in Japan, between April 2014 and March 2022. Medical records were checked to see if the patient had practically committed behaviors that corresponded to fireplay or arson. The case group was identified using this process. After identifying the case and control groups, sex, diagnosis, antisocial behavior, abuse history, and children-to-parent violence were assessed and compared by careful review of medical records. RESULTS: The study identified 64 patients who engaged in fireplay or arson, representing approximately 1.1% of the total 5,587 patients (case group). The median age of the patients' first fire-related behavior was 13 years (range, 6-18 years). In the case group, 14.1% of the cases involved arson, resulting in substantial damage. Of the remaining 5523 patients, 2268 patients had datasets for the first consultation (control group). The most prevalent diagnosis in the case group was attention-deficit hyperactivity disorder (ADHD), present in 57.8% of the cases. The study revealed a significant association between fire-related behaviors and ADHD as well as antisocial behavior. Gender differences were observed, with boys being more likely to engage in fireplay or arson than girls. CONCLUSIONS: This study suggests that clinicians and mental health professionals should closely consider male sex, ADHD, and antisocial behaviors as potential risk factors for fire-related behaviors. Monitoring the case group for the development of psychiatric disorders, including the use of illegal drugs, is recommended to prevent future arson incidents.
ABSTRACT
INTRODUCTION: Coronavirus disease 2019 (COVID-19) symptoms are not fully understood in non-hospitalized individuals in Japan, and COVID-19 differentiation by symptoms alone remained challenging. Therefore, this study aimed to examine COVID-19 prediction from symptoms using real-world data in an outpatient fever clinic. METHODS: We compared the symptoms of COVID-19-positive and negative patients who visited the outpatient fever clinic at Imabari City Medical Association General Hospital and tested for COVID-19 from April 2021 to May 2022. This retrospective single-center study enrolled 2,693 consecutive patients. RESULTS: COVID-19-positive patients had a higher frequency of close contact with COVID-19-infected patients compared with COVID-19-negative patients. Moreover, patients with COVID-19 had high-grade fever at the clinic compared with patients without COVID-19. Additionally, the most common symptom in patients with COVID-19 was sore throat (67.3%), followed by cough (62.0%), which was approximately twice as common in patients without COVID-19. COVID-19 was more frequently identified in patients having a fever (≥37.5â) with a sore throat, a cough, or both. The positive COVID-19 rate reached approximately half (45%) when three symptoms were present. CONCLUSION: These results suggested that COVID-19 prediction by combinations of simple symptoms and close contact with COVID-19-infected patients might be useful and lead to recommendations for testing of COVID-19 in symptomatic individuals.
ABSTRACT
A 72-year-old male had pseudomonal enteritis related to pembrolizumab. Chemotherapy for hypopharyngeal carcinoma with lung metastasis comprised cisplatin, 5-FU, and pembrolizumab. On day 14 of chemotherapy treatment he had a sudden prominent abdominal bulge, decreased consciousness, and drop in blood pressure in septic shock. CT scan showed marked intestinal gas through to intrahepatic bile ducts. Pseudomonas aeruginosa was simultaneously detected in both blood and stool cultures. Intestinal endoscopy revealed ulcerative lesions from the transverse colon to the rectum. Pathological investigations indicated apoptosis of the villus. The patient was diagnosed with pseudomonal enteritis induced by immune-related adverse events from the use of pembrolizumab. Treatment by corticosteroid and meropenem were subsequently switched to cefepime and metronidazole, and this successfully improved his colitis. In this new era of biological-targeted drugs and as clinical experience grows, we recommend a high level of alertness for potential diagnosis of infectious complications.

During the COVID-19 pandemic, the incidence of eating disorders (ED) has increased not only in Japan but also worldwide. This online survey for pediatricians showed that caregivers tend to visit specific pediatric institutions or child psychiatry departments when children under junior high school age develop eating disorders. There are few pediatric institutions regarding treatment acceptance for children with ED. Of the 34 respondents, 16 (47.1%) answered that the number of visits for children with eating disorders had "stayed the same", one answered it had "decreased" and 17 (50.0%) answered it had "increased" or "increased very much". In addition, 28 of the 34 respondents (82.3%) experienced difficulties with psychotherapy for children with ED. For treating children with ED, pediatricians usually conducted physical examination and have some clinical burden. ED are increasing in the COVID-19 pandemic. Because children with severe ED need to be hospitalized, child and adolescent psychiatric wards are overcrowded and some children with other mental disorders can't be admitted.
ABSTRACT
A 70-year-old woman was admitted to our hospital due to bilateral optic neuritis and left facial sensory disturbance that became exacerbated over 10 days. Both serum and cerebrospinal fluid (CSF) were negative for aquaporin 4 antibody and myelin oligodendrocyte glycoprotein antibody. A high level of myelin basic protein (MBP) in her CSF was observed. Brain MRI showed a high T2 signal and contrast enhancement of the bilateral optic nerve, intramedullary tract and central myelin lesion in the trigeminal nerve. After intravenous methylprednisolone pulse therapy, her visual impairment and facial sensory disturbance gradually improved. She was diagnosed with clinically isolated syndrome, based on 2017 McDonald criteria. A diagnosis of multiple sclerosis (MS) was suspected due to the trigeminal myelin lesion confined to the central myelin portion and high level of MBP in the CSF. Treatment with dimethyl fumarate has been effective for preventing recurrence in 13 months in this patient. The central-peripheral myelin transitional zone at the trigeminal nerve is located 1-6 mm from the pons, where central myelin changes to the peripheral myelin. This patient showed a high T2 signal at the trigeminal nerve 3 mm from the pons on MRI, suggesting the involvement of a central trigeminal myelin lesion. Findings of a central trigeminal myelin lesion on MRI may aid in differentiating between MS and seronegative neuromyelitis optica spectrum disorder.

Background: The population affected by colorectal cancer is growing, and there is an increasing need for prevention of functional decline following treatment. We proposed that the Kihon Checklist published by the Japanese Ministry of Health, Labor, and Welfare would be an appropriate means of frailty assessment for prediction of postoperative complications in older patients with colorectal cancer. This prospective cohort study aims to identify the factors influencing postoperative frailty. Methods: We prospectively enrolled consecutive patients with colorectal cancer and aged ≥ 65 year (N = 500) between May 2017 and December 2018. Eligible patients were assessed with the Kihon Checklist prior to surgery and 30 days after surgery. The main measures were variables related to postoperative change in view of frail status. Results: According to the Kihon Checklist questionnaire, 164 patients were frail preoperatively and 172 patients were frail postoperatively, whereas 38 patients changed from "nonfrail" before surgery to postoperative "frail." Overall complications were counted in 97 patients (19.4%), and 5 patients died. Performance status ≥ 2, history of laparotomy, open surgery, complication, ostomy creation, and delirium were significantly associated with changing postoperative "frail" (P = .014, P = .023, P = .006, P < .001, P = .023, and P = .024, respectively). In multivariate analysis, independent related factors of changing postoperative "frail" were complication (odds ratio 2.69, 95% confidence interval 1.19-6.09, P = .018) and ostomy creation (odds ratio 2.32, 95% confidence interval 1.01-5.33, P = .047). Conclusion: The Kihon Checklist questionnaire could identify the factors related to postoperative change of frailty status in older patients with colorectal cancer. This cohort concluded that whether postoperative complication occurred or not was closely associated with perioperative change of frailty status.
ABSTRACT
Goblet cell adenocarcinoma is extremely rare tumor in which the same cells have both exocrine and neuroendocrine properties. It is considered to be more aggressive than conventional carcinoids and more likely to cause metastasis. We report a case of goblet cell adenocarcinoma that developed late peritoneal recurrence, and we review pertinent literature. A 63-year-old male underwent appendectomy for acute appendicitis. Histopathological findings of appendectomy specimen showed mixed adenoneuroendocrine carcinoma, and positive resection margin. He also underwent laparoscopic ileocecal resection and apical lymph node dissection. After 9 years, he presented with ileus and abdominal CT examination indicated possible peritoneal dissemination. Laparoscopic observation revealed disseminated nodules throughout the entire abdominal cavity, and the patient underwent resection of the omental nodule and gastrointestinal bypass surgery. Previous appendectomy specimens showed goblet cell adenocarcinoma (GCA) according to the 5th edition of the WHO classification. Omental specimens confirmed the histopathological findings, and we diagnosed peritoneal recurrence of appendiceal goblet cell adenocarcinoma. Goblet cell adenocarcinoma may develop and cause late recurrence, and long-term follow-up may be required.
ABSTRACT
INTRODUCTION: The interaction of CD155 with its ligand, the T cell immunoreceptor with Ig and ITIM domains (TIGIT), is being studied owing to its potential to act as a target in the treatment of various solid tumors. However, the relationship between CD155 and TIGIT in colorectal cancer (CRC) prognosis is not known. We hypothesized that the TIGIT-CD155 pathway suppresses the attack of T cells on tumors, thereby affecting CRC prognosis. METHODS: We examined the expression of CD155 and TIGIT using immunohistochemical staining in 100 consecutive patients with CRC who underwent complete resection of ≤Stage III tumors at Wakayama Medical University Hospital between January and December 2013. We assessed the correlation between CD155 and TIGIT expressions and prognosis as well as the clinicopathological background of CD155 and TIGIT. RESULTS: Patients with high CD155 and TIGIT expressions showed worse prognosis than those with other levels of expression (p = 0.026). In multivariate analysis that also included the existing prognostic markers, high CD155 and TIGIT expressions were identified as independent poor prognostic factors. CONCLUSIONS: The interaction between CD155 and TIGIT possibly plays an important role in the immunological mechanism of CRC. Therefore, it may be possible to effectively predict the postoperative prognosis of CRC by evaluating the combined expression of CD155 and TIGIT. The study findings suggest that CD155 and TIGIT can predict clinical outcomes, thereby contributing to the personalized care of CRC.
