ABSTRACT
Tertiary lymphoid structures (TLSs) are complex lymphocyte clusters that arise in non-lymphoid tissues due to inflammation or cancer. A mature TLS with proliferating germinal centers is associated with a favorable prognosis in various cancers. However, the effect of TLS maturity on advanced colorectal cancer (CRC) remains unexplored. We analyzed the significance of TLS maturity and tumor Ki-67 expression in surgically resected tumors from 78 patients with pathological T4 CRC. Mature TLS was defined as the organized infiltration of T and B cells with Ki-67-positive proliferating germinal centers. We analyzed the relationship between TLS maturity and intratumoral immune cell infiltration. Mature TLS with germinal center Ki-67 expression was associated with microsatellite instability and improved survival; however, high tumor Ki-67 expression was associated with poor survival in the same cohort. Multivariate analysis identified the absence of mature TLS as an independent predictor of poor post-recurrence overall survival. Intratumoral infiltration of T lymphocytes and macrophages was significantly elevated in tumors with mature TLS compared to those lacking it. High Ki-67 levels and absent mature TLS were identified as poor prognostic factors in advanced CRC. Mature TLS could serve as a promising marker for patients at high-risk of CRC.
ABSTRACT
PURPOSE: Recombinant human fibroblast growth factor-2 (rhFGF-2) has demonstrated positive effects on wound healing at 2 weeks after periodontal surgery relative to enamel matrix derivative (EMD). However, the effects at earlier postoperative stages have not been reported. This retrospective study compared the early wound healing outcomes 1 week after surgery using the modified papilla preservation technique (mPPT) with either EMD or rhFGF-2 therapy. METHODS: We compiled a list of all mPPT sites treated with EMD or rhFGF-2 during the survey period (September 2011 to March 2022). Early wound healing was assessed using the early wound healing score (EHS) and the modified early wound healing index (mEHI). Inter-rater reliability for the EHS and mEHI was established using intraclass correlation coefficients. Factors influencing mPPT were identified by analyzing the correlation coefficients between the EHS items, mEHI items, and potential influencing factors. After adjusting for factors impacting EHS, mEHI, and mPPT, we compared the EHS and mEHI between EMD and rhFGF-2 groups. RESULTS: In total, 72 sites were evaluated. The scores for incision line, step, and dehiscence were significantly higher in those receiving rhFGF-2 (n=42) compared to those treated with EMD (n=30). The EHS item scores did not differ significantly between groups. Among patients aged ≥50 years, but not those <50 years, significantly higher step and dehiscence scores were found in the rhFGF-2 group than the EMD group (P<0.01). Additionally, for patients exhibiting a clinical attachment level (CAL) ≥8 mm, the step score was significantly higher in the rhFGF-2 group than in the EMD group (P<0.05), but this trend was not reflected in those with a CAL <8 mm. CONCLUSIONS: In this study, early wound closure at mPPT sites was more effectively achieved with rhFGF-2 than with EMD. Nevertheless, biochemical assessments are required to compare the re-epithelialization effects of these therapies.
ABSTRACT
BACKGROUND/AIM: Adjuvant capecitabine and oxaliplatin (CAPOX) therapy is standard strategy for colorectal cancer with risk of recurrence. Early dose reduction (EDR) of CAPOX therapy is commonly used in real-world practice. However, there is limited evidence regarding the effectiveness of CAPOX for patients who had EDR. Therefore, this study aimed to clarify the risks of EDR and its effect on long-term outcomes and body composition factors. PATIENTS AND METHODS: Patients who received CAPOX therapy after radical surgery for colorectal cancer between June 2013 and December 2021 were included. EDR was defined as dose reduction within four courses of CAPOX therapy. Body composition factors were measured for 1 year following surgery to determine the EDR effects. RESULTS: Eighty-four patients were included; 35 (42%) of them had EDR. The multivariate analysis revealed that underweight [odds ratio (OR)=4.95, 95% confidence interval (CI)=1.13-21.7, p=0.03] was a risk factor for EDR. Relapse-free survival (RFS) was significantly better in the non-EDR group (p=0.01). The 5-year RFS rates for the non-EDR and EDR groups were 88.7% and 65.4%, respectively. The multivariate analysis revealed that age >65 years [hazard ratio (HR)=3.97; 95% CI=1.16-13.62, p=0.03] and EDR (HR=7.62; 95% CI=1.71-33.91, p=0.005) were associated with poorer RFS. The 1-year body composition analysis revealed decreases in all factors in the EDR group. CONCLUSION: Preoperative underweight status was associated with EDR, which resulted in decreased RFS and body composition factors when compared with the non-EDR group. Therefore, avoiding EDR and early nutritional intervention after EDR may improve outcomes.

PURPOSE: This study aimed to identify cases in which lateral lymph node (LLN) dissection (LLND) can be excluded by clarifying preoperative factors, including an evaluation of the middle rectal artery (MRA), associated with LLN metastasis. METHODS: Fifty-five consecutive patients who underwent preoperative positron emission tomography-computed tomography (PET/CT) and total mesorectal excision with LLND for rectal cancer were included. We retrospectively investigated the preoperative clinical factors associated with pathological LLN (pLLN) metastasis. We analyzed the regions of pLLN metastasis using MRA. RESULTS: pLLN metastasis occurred in 13 (23.6%) patients. According to a multivariate analysis, clinical LLN (cLLN) metastasis based on short-axis size and LLN status based on PET/CT were independent preoperative factors of pLLN metastasis. The negative predictive value (NPV) was high (97.1%) in patients evaluated as negative based on PET/CT and cLLN short-axis size. MRA was detected in 24 patients (43.6%) using contrast-enhanced CT, and there was a significant relationship between pLLN metastasis and the presence of MRA. pLLN metastasis in the internal iliac region but not in the obturator region was significantly correlated with the presence of MRA. CONCLUSION: Combined cLLN metastasis based on short-axis size and PET/CT showed a higher NPV, suggesting this to be a useful method for identifying cases in which LLND can be excluded.
ABSTRACT
Aorto-esophageal fistula (AEF) due to esophageal cancer (EC) is a life-threatening condition characterized by sudden hemorrhage, which often causes sudden death. To evaluate the efficacy and safety of thoracic endovascular aortic repair (TEVAR) for AEF due to EC, we performed a systematic review and meta-analysis. We searched the MEDLINE (PubMed) databases, the Cochrane Library databases, Ichushi-Web (the databases of the Japan Medical Abstract Society), and CiNii (Academic information search service of the National Institute of Information from Japan) from January 2000 to November 2023 for articles about TEVAR for an emergent aortic hemorrhage (salvage TEVAR [S-TEVAR]), and the prophylactic procedure (P-TEVAR). Six studies (140 cases) were eligible for meta-analysis. The 90-day mortality of S-TEVAR and P-TEVAR was 40% (95% CI 23-60, I2 = 36%) and 8% (95% CI 3-17, I2 = 0%), respectively. Post-S-TEVAR hemorrhagic and infectious complications were 17% (95% CI 3-57, I2 = 71%) and 20% (95% CI 5-57, I2 = 66%), respectively. Post-P-TEVAR hemorrhagic and infectious complications were 2% (95% CI 0-10, I2 = 0%) and 3% (95% CI 1-12, I2 = 0%), respectively. TEVAR for AEF due to EC may be a useful therapeutic option to manage or prevent hemorrhagic oncological emergencies.

Tumor-infiltrating immune cells, such as lymphocytes and macrophages, have been associated with tumor aggressiveness, prognosis and treatment response in colorectal cancer (CRC). An immune scoring system, Immunoscore (IS), based on tumor-infiltrating T cells in stage I-III CRC, was used to predict prognosis. An alternative immune scoring signature of immune activation (SIA) reflects the balance between anti- and pro-tumoral immune components. The present study aimed to evaluate the prognostic value of modified IS (mIS) and modified SIA (mSIA) in locally advanced pathological T4 (pT4) CRC, including stage IV CRC. Immunohistochemical staining for immune cell markers, such as CD3 (pan-T cell marker), CD8 (anti-tumoral cytotoxic T cell marker) and CD163 (tumor-supportive macrophage marker), in specimens from patients with radically resected pT4 CRC at stages II-IV was performed. mIS levels in the T4 CRC cohort were not associated with prognosis. However, low mSIA levels were associated with low survival. Furthermore, low mSIA was an independent predictor of recurrence in patients with radically resected pT4 CRC. In patients with CRC who did not receive postoperative adjuvant chemotherapy, low mSIA was a major poor prognostic factor; however, this was not observed in patients receiving adjuvant chemotherapy. Evaluation of the tumor-infiltrating immune cell population could serve as a valuable marker of recurrence and poor prognosis in patients with locally advanced CRC. mSIA assessment after radical CRC resection may be promising for identifying high-risk patients with pT4 CRC who require aggressive adjuvant chemotherapy.
ABSTRACT
BACKGROUND: Here, we describe the precise surgical technique for a novel procedure involving 2-team transanal total mesorectal excision with en bloc lateral pelvic lymph node (LPLN) dissection combined with resection of the involved main internal iliac vessels and pelvic plexus. METHODS: From September 2020 to May 2023, 4 patients underwent the procedure at our hospital. RESULTS: The operation time and blood loss were 272 to 412 minutes and 10 to 124 mL, respectively. No patients required conversion to open surgery or exhibited Clavien-Dindo grade III or worse postoperative complications, although 2 developed grade II urinary dysfunction. All surgical margins were negative. CONCLUSIONS: Our novel 2-team method can facilitate safe and satisfactory surgery, even for highly advanced rectal cancer. The transanal approach offers excellent visibility and operability, even during LPLN and adjacent structure dissection. Furthermore, initial dissection of the distal branches of the iliac vessels prevents excessive lymphatic tissue congestion, facilitating easier, and clearer dissection.

PURPOSE: Enamel matrix derivative (EMD) has demonstrated beneficial effects on wound healing following surgery. However, the effects of recombinant human fibroblast growth factor 2 (rhFGF-2) in periodontal regeneration therapy have not been extensively studied. This retrospective study was conducted to compare the wound healing outcomes of the modified papilla preservation technique (mPPT) between EMD and rhFGF-2 therapies. METHODS: A total of 79 sites were evaluated for early wound healing using the modified early wound healing index (mEHI), which included 6 items: incision, fibrin clotting, step, redness, swelling, and dehiscence. A numeric analog scale, along with postoperative images of the 6 mEHI items, was established and used for the evaluations. The inter-rater reliability of the mEHI was assessed via intraclass correlation coefficients (ICCs). After adjusting for factors influencing the mPPT, the differences in mEHI scores between the EMD and rhFGF-2 groups were statistically analyzed. Additionally, radiographic bone fill (RBF) was evaluated 6 months after surgery. RESULTS: The ICC of the mEHI was 0.575. The mEHI, redness score, and dehiscence scores were significantly higher in the rhFGF-2 group (n=33) than in the EMD group (n=46). Similar results were observed in the subgroup of patients aged 50 years or older, but not in those younger than 50 years. In the subgroup with non-contained bone defects, related results were noted, but not in the subgroup with contained bone defects. However, early wound healing did not correlate with RBF at 6 months after surgery. CONCLUSIONS: Within the limitations of this study, the findings suggest that early wound healing following the use of mPPT with rhFGF-2 is somewhat superior to that observed after mPPT with EMD. However, mEHI should be improved for use as a predictive tool for early wound healing and to reflect clinical outcomes after surgery.
ABSTRACT
PURPOSE: This study investigated the relationship between the number of days that hospital visits were postponed and changes in clinical parameters due to the spread of coronavirus disease 2019 (COVID-19), after the Japanese government declared a state of emergency in April 2020. METHODS: Regarding the status of postponement of appointments, we analyzed the patients who had visited the Nihon University Hospital at Matsudo for more than 1 year for supportive periodontal therapy (SPT) and classified them into low-, moderate- and high-risk subgroups according to the periodontal risk assessment (PRA). Clinical parameters for periodontal disease such as probing depth (PD), full-mouth bleeding score (FMBS), full-mouth plaque score, periodontal inflamed surface area (PISA), and periodontal epithelial surface area (PESA) were analyzed in 2 periods, from October 2019 to March 2020 and after April 2020. Correlation coefficients between days of deferral and the degree of changes in clinical parameters were calculated. RESULTS: The mean age of the 749 patients was 67.56±10.85 years, and 63.82% were female. Out of 749 patients, 33.24% deferred their SPT appointments after April 2020. The average total of postponement days was 109.49±88.84. The number of postponement days was positively correlated with changes in average PD (rs=0.474) and PESA (rs=0.443) in the high-risk subgroup of FMBS, and average PD (rs=0.293) and PESA (rs=0.253) in the high-risk subgroup of tooth number (TN). Patients belonging to the high-risk subgroups for both FMBS and TN had a positive correlation between postponement days and PISA (rs=0.56). CONCLUSIONS: The findings, the spread of COVID-19 appears to have extended the visit interval for some SPT patients. Moreover, longer visit intervals were correlated with the worsening of some clinical parameters for SPT patients with high PRA.
ABSTRACT
BACKGROUND/AIM: Lateral lymph node dissection is a locally advanced rectal cancer treatment option. Despite its complexities, such as prolonged operative time and increased blood loss, a transanal approach with an abdominal approach may help mitigate these drawbacks. PATIENTS AND METHODS: Between July 2013 and June 2022, 40 patients underwent radical laparoscopic surgery with lateral lymph node dissection for rectal cancer. Among them, 29 and 11 patients underwent total mesorectal excision and lateral lymph node dissection without transanal approach (conventional surgery) and with transanal approach (two-team surgery), respectively. The clinical findings, surgical outcomes, pathology results, and prognoses of conventional and two-team surgeries were retrospectively compared. RESULTS: Compared to conventional surgery, two-team surgery involves increased organ and nerve resections, shorter operation time (286 vs. 548 min, p<0.001), and less blood loss (20 vs. 158 ml, p<0.001). Although postoperative complications were similar between groups, the two-team surgery group had a shorter hospital stay (p=0.006). Pathologically, all patients who underwent two-team surgery had a distal resection margin of at least 20 mm, and no recurrence was observed. With conventional surgery, 63.6% of patients had a 10-19 mm margin, and 36.4% had a margin of ≥20 mm, except for abdominoperineal resection. CONCLUSION: Total mesorectal excision and lateral lymph node dissection with the transanal approach as a two-team surgery are safe and feasible. Two-team surgery resulted in better outcomes than conventional surgery regarding operative time, blood loss, shorter postoperative hospital stay, and adequate distal resection margin.

Irinotecan (CPT-11) is an anticancer drug with indications for use in treating various cancers, but severe diarrhea develops as a side effect. We investigated the effects of green tea extract (GTE) on CPT-11-induced diarrhea, focusing on ß-glucuronidase and intestinal UGT1A1. When CPT-11 was administered to rats alone, the fecal water content was approximately 3.5-fold higher in this group than in the control group, and diarrhea developed. The fecal water content in the GTE-treated group was significantly higher than that in the control group, but the difference was smaller than that between the group treated with CPT-11 alone and the control group, and diarrhea improved. When CPT-11 was administered alone, the abundances of Bacteroides fragilis and Escherichia coli, which are ß-glucuronidase-producing bacteria, increased and interleukin-6 and interleukin-1ß mRNA levels in the colon increased, but GTE suppressed these increases. CPT-11 decreased colon UGT1A1 and short-chain fatty acid levels; however, this decrease was suppressed in the GTE-treated group. The findings that GTE decreases the abundance of ß-glucuronidase-producing bacteria and increases colon UGT1A1 levels, thereby decreasing the production of the active metabolite SN-38 in the intestinal tract, indicate that GTE ameliorates CPT-11-induced diarrhea.

PURPOSE: Exosomes are membrane vesicles that are present in body fluids and contain proteins, lipids, and microRNA (miRNA). Periodontal tissue examinations assess the degree of periodontal tissue destruction according to the probing depth (PD), clinical attachment loss (CAL), bleeding on probing, and X-ray examinations. However, the accurate evaluation of the prognosis of periodontitis is limited. In this study, we collected saliva from patients before and after initial periodontal therapy (IPT) and compared changes in the clinical parameters of periodontitis with changes in the components of salivary exosomes. METHODS: Saliva was collected from patients with stage III and IV periodontitis at the first visit and post-IPT. Exosomes were purified from the saliva, and total protein and RNA were extracted. Changes in expression levels of C6, CD81, TSG101, HSP70, and 6 kinds of miRNA were analyzed by western blots and real-time polymerase chain reaction. RESULTS: Patients with increased C6 expression after IPT had significantly higher levels of periodontal inflamed surface area (PISA), miR-142, and miR-144 before and after IPT than patients with decreased C6 expression after IPT. Patients with decreased and unchanged CD81 expression after IPT showed significantly higher PD, CAL, and PISA before IPT than after IPT. Patients with decreased and unchanged TSG101 expression after IPT had significantly higher PD before IPT than after IPT. Patients with increased HSP70 expression after IPT had significantly higher PD and PISA before and after IPT than patients with unchanged HSP70 after IPT. The expression levels of miR-142, miR-144, miR-200b, and miR-223 changed with changes in the levels of C6, CD81, TSG101, and HSP70 in the salivary exosomes of periodontitis patients before and after IPT. CONCLUSIONS: The expression levels of proteins and miRNAs in salivary exosomes significantly changed after IPT in periodontitis patients, suggesting that the components of exosomes could serve as biomarkers for periodontitis.
ABSTRACT
Nutritional factors reflect the periodontal parameters accompanying periodontal status. In this study, the associations between nutritional factors, blood biochemical items, and clinical parameters were examined in patients with systemic diseases. The study participants were 94 patients with heart disease, dyslipidemia, kidney disease, or diabetes mellitus. Weak negative correlation coefficients were found between nine clinical parameters and ten nutritional factors. Stage, grade, mean probing depth (PD), rate of PD 4−5 mm, rate of PD ≥ 6 mm, mean clinical attachment level (CAL), and the bleeding on probing (BOP) rate were weakly correlated with various nutritional factors. The clinical parameters with coefficients of determinations (R2) > 0.1 were grade, number of teeth, PD, rate of PD 4−5 mm, CAL, and BOP rate. PD was explained by yogurt and cabbage with statistically significant standardized partial regression coefficients (yogurt: −0.2143; cabbage and napa cabbage: −0.2724). The mean CAL was explained by pork, beef, mutton, and dark green vegetables with statistically significant standardized partial regression coefficients (−0.2237 for pork, beef, and mutton; −0.2667 for dark green vegetables). These results raise the possibility that the frequency of intake of various vegetables can be used to evaluate periodontal stabilization in patients with systemic diseases.

Protein-protein interactions are essential in biological reactions and fundamental to cell-cell communication (e.g., the binding of secreted proteins, such as hormones, to cell membrane receptors) and the subsequent intracellular signal transduction cascade. Several studies have been extensively carried out on protein-protein interactions because they have the potential to resolve various problems in molecular biology. Biochemical methods, such as chemical cross-linking and immunoprecipitation, have long been used to analyze which proteins interact with each other. However, there are some problems, such as unphysiological states and non-specific binding, that require the development of more useful experimental methods. This chapter discusses the "proximity labeling (Proteomics)" analysis technique, which has been attracting attention in protein-protein interaction analysis in recent years and is used in many biological studies. "Membrane proximity labeling (proteomics)," which analyzes the interaction of cell membrane proteins, and "intracellular proximity labeling (proteomics)" will be explained in-depth.

BACKGROUND/AIM: We investigated the relationship between prognosis and the necessity of decompression of large bowel obstruction (LBO) among patients with colorectal cancer admitted to the hospital in an emergency, as well as the correlation between prognosis and improvement in the C-reactive protein-to-albumin ratio (CAR) after decompression. PATIENTS AND METHODS: Seventy-four patients admitted to the hospital between 2013 and 2021 in an emergency due to LBO were included. We examined perioperative clinicopathological factors, bowel decompression type, and prognosis. RESULTS: Of the 74 patients, 24 (32.4%) required bowel decompression. A higher percentage of patients who required bowel decompression had a colorectal obstruction scoring system (CROSS) score 0 (p<0.001) with higher frequency of nutritional disorders (p=0.063) than that in no bowel decompression-requiring patients. The 3-year-disease-free survival was 70.8% in the no decompression-requiring group and 26.9% in the bowel decompression group (p=0.007), while the 3-year-overall survival was 90.8% and 76.5%, respectively (p=0.001). The 3-year-disease-free survival was 49.2% in the improved CAR group and 0.0% in the non-improved CAR group (p=0.024), while the 3-year-overall survival was 91.7% and 56.3%, respectively (p=0.061). CONCLUSION: The necessity of emergency decompression was associated with a poorer prognosis, compared to the no decompression-requiring group. Similarly, a CROSS score of 0 was an independent poor prognostic factor. Among patients who required emergency bowel decompression, those who showed improvement in CAR before and after decompression treatment had a better prognosis than those who did not.

BACKGROUND/AIM: We evaluated the long-term outcome of docetaxel, cisplatin, and 5-fluorouracil as combination chemoradiotherapy (DCF-RT) for patients with potentially resectable esophageal cancer (EC) in clinical settings. PATIENTS AND METHODS: Twenty-eight patients with potentially resectable thoracic EC were included in this study. Chemotherapy consisted of intravenous docetaxel at 50 mg/m2 (day 1), CDDP at 60 mg/m2 (day 1), and 5-FU at 600 mg/m2 (days 1 to 4), repeated every four weeks for two cycles along with radiotherapy (60 Gy in 30 fractions). Potentially resectable esophageal cancer was defined as clinical stage (cStage) I, II, III, and IV with supraclavicular lymph node metastasis [M1(Lym)]. RESULTS: The overall complete response (CR) rate was 88.5%. The 5-year overall survival (OS) rates for cStage I, cStage II-III, and IV [M1(lym)] patients were 79.5%, 76.2%, and 50.0%, respectively. The most frequent grade 3 or 4 acute toxicities were leucopenia (85.7%), neutropenia (78.5%), and febrile neutropenia (FN) (21.4%). The rate of any grade 3 or 4 late toxicity was 7.7%. CONCLUSION: DCF-RT demonstrated a satisfactory CR rate and OS with a higher rate of FN for potentially resectable thoracic EC patients. Prophylactic treatment with granulocyte-colony-stimulating factor and antibiotics may be appropriate supportive care for patients undergoing DCF-RT.

BACKGROUND: Despite the potential efficacy of hospital-based multidisciplinary child protection team (CPTs), research analyzing Japanese CPT databases is scarce. OBJECTIVE: We aimed to describe the characteristics of children and families reported to a CPT in Japan and investigate factors associated with the substantiation of maltreatment. PARTICIPANTS AND SETTING: This retrospective, cross-sectional study took place in a national children's hospital in Japan and included 350 children who were reported to CPTs between April 2014 and March 2018. METHODS: Univariable and multivariable logistic regression analyses were conducted using the CPT database and medical records. RESULTS: Among 350 cases, 33.4 % were substantiated. Children of <6 years of age comprised 73.4 % of the cases. The majority (67.7 %) received an injury-related diagnosis and physical maltreatment was suspected in 68.3 % of cases. In the univariable analysis, older age, a primary diagnosis other than injury, reporting department, psychological maltreatment, witnessing intimate partner violence, maltreatment by relatives other than biological father or mother, developmental disability, emotional/behavioral difficulty or psychological disorder, maternal/paternal psychological difficulty, and maternal history of maltreatment were significantly associated with substantiation. When adjusted for demographic, child and familial factors, a diagnosis other than injury (AOR 2.02, 95 % CI = 1. 11-3.65) and parental psychological difficulties (AOR 2.49, 95 % CI = 1.37-4.55) were independently associated with substantiation. CONCLUSION: Most cases reported to our CPT were young children with an injury-related diagnosis. Substantiation was associated with a diagnosis other than injury and parental psychological difficulties. Further prospective and comprehensive studies are needed to establish universal guidelines for databases of hospital-based CPTs.

BACKGROUND/AIM: Nutritional disorders due to cancer-related weight loss, such as cancer-impaired food passage, are prominent in many cases of advanced oesophageal cancer. Here, we investigated the nutritional factors that most affect the therapeutic effect and prognosis of unresectable oesophageal cancer. PATIENTS AND METHODS: One hundred four patients diagnosed with cT4b oesophageal squamous cell carcinoma were included in this study. The values of C-reactive protein/albumin ratio, Glasgow Prognostic Score, prognostic nutritional index, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio were calculated from the pre-treatment blood sampling results of the patients who received chemoradiotherapy, and the therapeutic effect and prognosis were analysed. RESULTS: High- C-reactive protein/albumin group and Glasgow Prognostic Score 1 or 2 group correlated with a significantly worse prognosis compared with the low- C-reactive protein/albumin group and Glasgow Prognostic Score 0 group regarding both disease-specific survival and overall survival. CONCLUSION: Evaluation of pre-treatment CRP and albumin levels in locally advanced oesophageal cancer leads to useful prognostic prediction.

INTRODUCTION: We evaluated the risk factors for patients with gastric cancer (GC) undergoing total gastrectomy (TG) that predict postoperative complications, including anastomotic leakage, postoperative pneumonia, and heart disease. METHODS: We collected 106 patients who received TG for GC between May 2009 and May 2017 at Gunma University Graduate School of Medicine, including clinicopathologic, surgical, postoperative complication, laboratory test, and physiologic test data. RESULTS: Of 106 patients, 92 (86.8%) had no complications, and 14 (13.2%) had complications. Univariate analyses revealed that a high American Society of Anaesthesiologists physical status (ASA-PS) and neutrophil-lymphocyte ratio (NLR) of ≥3.5 significantly correlated with postoperative complications. Multivariate analyses showed that high ASA-PS was an independent prognostic factor of postoperative complications. The cancer recurrence rate was 34.8% in the noncomplication group and 71.4% in the complication group. CONCLUSION: Patients with postoperative complications are prone to recurrence and poor prognosis. For patients with high-risk GC with poor ASA-PS and high NLR, more thorough perioperative management is essential.
