RESUMO

BACKGROUND: Inguinal herniation of the urinary bladder is uncommon and those descending into the scrotum are even rarer. Although open anterior repair has been used for inguinal bladder hernia, the efficacy of laparoscopic herniorrhaphy has been reported in recent years. CASE PRESENTATION: A 63-year-old man presented with an irreducible right groin and scrotal bulge associated with voiding difficulty. Abdominal ultrasonography showed a dislocation of the urinary bladder descending into the right scrotum. Abdominal CT imaging revealed that a part of the bladder and small intestine was herniating into the scrotum through the internal inguinal ring and running laterally to the inferior epigastric artery. Under the diagnosis of indirect inguinal bladder hernia, the patient underwent trans-abdominal preperitoneal hernia repair (TAPP). The bladder herniated into the scrotum through the internal inguinal ring was replaced to the original position. Then the myopectineal orifice was exposed and covered with polypropylene mesh, where a horizontal peritoneal incision 4 cm above the hernia orifice, i.e., the high peritoneal incision approach (HPIA), allowed an easy peeling of the peritoneum and hernia sac. The patient's postoperative course was uneventful and the voiding difficulty resolved. The patient continued to do well without recurrence at 20 months after surgery. CONCLUSION: Preoperative evaluation with abdominal ultrasonography and CT scan allowed a precise diagnosis of a groin hernia with voiding difficulty. TAPP with HPIA was useful in the treatment of inguinal bladder hernia because this technique facilitated a quick confirmation of the hernia contents, secure dissection of the whole protruded bladder, and adequate replacement of the bladder to the original position without any injury.

RESUMO

We report a case of pulmonary tuberculosis developed during chemotherapy for colon cancer. A 78-year-old man with dyspnea was referred to our hospital for the treatment of transverse colon cancer with duodenal invasion. Chemotherapy was initiated for severe respiratory dysfunction associated with emphysema. After 3 months of chemotherapy, the patient required hospitalization because of severe general fatigue and appetite loss. Pneumonia occurred on the 9th hospital day. Antibiotic therapies with cefotiam hydrochloride or tazobactam/piperacillin were ineffective, his respiratory condition gradually decreased, and thus, endotracheal intubation was required. The patient was finally diagnosed with pulmonary tuberculosis by acid-fast staining of the sputum. Antituberculosis therapy with rifampicin, isoniazid, and streptomycin was effective, and acid-fast staining became negative after 2 weeks of antituberculosis therapy. However, he could not withdraw from the ventilator support and died of cancer progression on the 94th hospital day. Because chemotherapies induce immunosuppression, a targeted screening for latent tuberculosis infection should be performed in patients with colorectal cancer who are highly at risk for tuberculosis before starting chemotherapy, and pulmonary tuberculosis should be ruled out when a patient develops symptoms of pneumonia during chemotherapy.

RESUMO

Some chemotherapeutic drugs can induce cancer cell death and enhance antitumor T-cell immunity in cancer-bearing hosts. Immunomodulatory reagents could augment such chemotherapy-induced effects. We previously reported that oral digestion of Lentinula edodes mycelia (L.E.M.) extract or  l-arginine supplementation can augment antitumor T-cell responses in cancer-bearing mice. In this study, the effects of L.E.M. extract with or without  l-arginine on the therapeutic efficacy of immunogenic chemotherapy by 5-fluorouracil (5-FU)/oxaliplatin (L-OHP) and/or cyclophosphamide (CP) are examined using two mouse colon cancer models. In MC38 and CT26 cancer models, therapy with 5-FU/L-OHP/CP significantly suppressed tumor growth, and supplementation with L.E.M. extract halved the tumor volumes. However, the modulatory effect of L.E.M. extract was not significant. In the CT26 cancer model, supplementation with L.E.M. extract and  l-arginine had no clear effect on tumor growth. In contrast, their addition to chemotherapy halved the tumor volumes, although the effect was not significant. There was no difference in the cytotoxicity of tumor-specific cytotoxic T cells generated from CT26-cured mice treated by chemotherapy alone versus chemotherapy combined with L.E.M. extract/ l-arginine. These results indicate that the antitumor effects of immunogenic chemotherapy were too strong to ascertain the effects of supplementation of L.E.M. extract and  l-arginine, but these reagents nonetheless have immunomodulatory effects on the therapeutic efficacy of immunogenic chemotherapy in colon cancer-bearing mice.

RESUMO

The short- and long-term outcomes of 34 patients with refractory malignant ascites who underwent peritoneovenous shunt (PVS) therapy were retrospectively reviewed. The primary disease was gastrointestinal cancer in 31 patients and gynecologic cancer in 3 patients. Regarding performance status, 21 patients had Eastern Cooperative Oncology Group Performance Status (PS) 2 and 13 patients were PS 3;thus, many were in a poor general condition. After treatment, abdominal distention disappeared in 79.4% of patients, and appetite improved in 60.9%. The median postoperative survival time was 38 days (range, 1-294 days), and 18 patients (52.9%) were discharged. Disseminated intravascular coagulation with clinical symptoms was observed in 3 patients (8.8%), and heart failure was observed in 7 patients (20.6%). PVS therapy was useful in improving the subjective symptoms of patients with refractory malignant ascites and in enabling them to receive care at home. However, serious postoperative complications are a concern, and appropriate preoperative evaluation is necessary.

RESUMO

BACKGROUND: Duplicated left gastric artery (LGA) is a rare anomaly. With an incidence of only 0.4%, its clinical significance remains largely unrecognized. CASE PRESENTATION: A 65-year-old man underwent robot-assisted distal gastrectomy for early gastric cancer. After division of the left gastric vein in the left gastropancreatic fold, a slim LGA (LGA-1) was identified and dissected. Careful dissection of the left gastropancreatic fold toward the root of the celiac artery revealed another LGA (LGA-2), which was dissected without difficulty. Postoperative reevaluation of the three-dimensional-computed tomography (CT) angiography reconstructed using the preoperative CT scan identified a 2.7 mm LGA-1, branching from the splenic artery, and a 3.0 mm LGA-2, branching from the celiac artery. To the best of our knowledge, this is only the third reported case of a duplicate LGA in a patient who underwent laparoscopic gastrectomy. Our case is the first to report the use of robot surgery. CONCLUSIONS: Although duplicate LGA is rare and receives little clinical attention, surgeons should keep this vascular anomaly in mind during preoperative evaluation since there is an increased risk for intraoperative bleeding during gastrectomy.

RESUMO

Background: The lack of tension at the anastomosis site and the blood flow of the gastric conduit are important to prevent anastomotic leakage in the anastomosis of the esophagogastric conduit. This study reports a gastric conduit stump closure method using Endo GIA™ Radial Reload in end-to-side anastomosis of the esophagogastric conduit, especially focusing on blood flow. Methods: A 4-cm conduit was created to ensure an intramural vascular network. The gastric conduit was elevated to the neck through the posterior mediastinal route, and end-to-side anastomosis of the esophagus and gastric conduit was performed using a circular stapler. Closure of the gastric stump with an Endo GIA Radial Reload was performed 2 cm proximal to the anastomosis on the end side of the esophagogastric conduit. The lesser curvature of the stump of the gastric conduit is the most frequent site of anastomotic leakage as it has the least blood flow, and the pressure is highest when the pressure inside the gastric conduit increases. Therefore, the gastric conduit stump was closed using the Endo GIA Radial Reload to resect the intersection of the gastric stump and lesser curvature from which the gastric conduit was created. The gastric conduit stump is gently curved; therefore, the pressure applied to the gastric conduit stump could be dispersed when the intragastric pressure increases. Results: No anastomotic leakage was observed among the 21 patients who underwent this method. Conclusion: This method is a novel anastomosis method to prevent anastomotic leakage in an end-to-side anastomosis of the esophagogastric conduit.

RESUMO

Myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs) are increased in cancer-bearing aged hosts. Arginase-I in MDSCs degrades L-arginine, an amino acid required for T cell activation and proliferation. In this study, we compared the therapeutic efficacy of 5-fluorouracil (5-FU)/oxaliplatin (L-OHP) and cyclophosphamide (CP) between young and aged colon cancer-bearing mice. Therapy with 5-FU/L-OHP and CP significantly suppressed the in vivo growth of CT26 and MC38 colon carcinomas in syngeneic young mice, whereas this effect was attenuated in aged mice. L-arginine monotherapy showed no effect in aged mice. However, additional therapy with anti-programmed cell death (PD)-1 antibody and L-arginine supplementation boosted the effect of chemoimmunotherapy in aged mice, and some mice were cured. During all combination therapy, tumor-specific cytotoxic T lymphocytes (CTLs) were generated from mice with non-progressing tumor, but not from those with progressing tumor. Plasma L-arginine levels were lower in aged than young mice, and chemotherapy tended to decrease the plasma L-arginine levels in aged mice. Compared to young mice, CT26-bearing aged mice decreased arginase activity, arginase-I expression, and the proportion of monocytic MDSCs in tumor tissues, whereas contrasting results were observed in MC38-bearing aged mice. Importantly, the induction of tumor-specific CTLs was impaired at lower doses of L-arginine in vitro, and the infiltration of CTLs into CT26 tissues after chemoimmunotherapy was promoted by L-arginine administration in vivo. These results indicate that chemoimmunotherapy was less effective in cancer-bearing aged mice, but that L-arginine supplementation can modulate its therapeutic efficacy via its effect on tumor-specific CTLs.

RESUMO

BACKGROUND: Risk factors for anastomotic leakage include local factors such as excessive tension across anastomosis and increased intraluminal pressure on the gastric conduit; therefore, we consider the placement of a nasogastric tube to be essential in reducing anastomotic leakage. In this study, we devised a safe and simple technique to place an NGT during an end-to-side, automatic circular-stapled esophagogastrostomy. METHODS: First, a 4-0 nylon thread is fixed in the narrow groove between the plastic and metal parts of the tip of the anvil head. After dissecting the esophagus, the tip of the NGT is guided out of the lumen of the cervical esophageal stump. The connecting nylon thread is applied to the anvil head with the tip of the NGT. The anvil head is inserted into the cervical esophageal stump, and a purse-string suture is performed on the esophageal stump to complete the anvil head placement. The main unit of the automated stapler is inserted through the tip of a reconstructed gastric conduit, and the stapler is subsequently fired and an end-to-side esophagogastrostomy is achieved. The main unit of the automated stapler is then pulled out from the gastric conduit, and the NGT comes out with the anvil head from the tip of the reconstructed gastric conduit. Subsequently, the nylon thread is cut. After creating an α-loop with the NGT outside of the lumen, the tip of the NGT is inserted into the gastric conduit along the lesser curvature toward the caudal side. Finally, the inlet of the automated stapler on the tip of the gastric conduit is closed with an automated linear stapler, and the esophagogastrostomy is completed. RESULTS: We utilized this technique in seven patients who underwent esophagectomy for esophageal cancer; smooth and safe placement of the NGT was accomplished in all cases. CONCLUSION: Our technique of NGT placement is simple, safe, and feasible.

RESUMO

BACKGROUND: This study aimed to evaluate the feasibility, safety, and efficacy of postoperative adjuvant chemotherapy with docetaxel/cisplatin/S-1 (DCS) following S-1 therapy in patients with stage III gastric cancer after curative gastrectomy. METHODS: Patients with stage III gastric cancer who underwent D2 gastrectomy were enrolled. Adjuvant chemotherapy was initiated within 8 weeks of gastrectomy. The first cycle of chemotherapy consisted of S-1 monotherapy (day 1-14), followed by a 7-day rest period. Cycles 2 and 3 consisted of the following: S-1 (day 1-14) administration, followed by a 14-day rest period, and an intravenous infusion of cisplatin and docetaxel on days 1 and 15. After two cycles, S-1 was administered for up to 1 year. RESULTS: Thirty patients were enrolled between 2014 and 2017. Febrile neutropenia of grade 3 or higher was the most common hematological toxicity with 4 patients (13.3%). Other hematological toxicities of grade 3 or higher were as follows: neutropenia in 3 (10.0%), leukopenia in 3 (10.0%), and anemia in 2 (6.7%) patients. Most frequent non-hematological toxicity of grade 3 was anorexia (n = 4, 13.3%) and general fatigue (n = 3, 10.0%); no grade 4 non-hematological toxicities were observed. Twenty-five patients (83.3%) completed two cycles of DCS treatment and 18 (60.0%) completed subsequent S-1 treatment for 1 year. The relative dose intensity of docetaxel and cisplatin was 0.86 and that of S-1 was 0.88. CONCLUSION: The DCS regimen can be acceptable as an adjuvant chemotherapy and offers an effective postoperative treatment option for stage III gastric cancer patients.

RESUMO

BACKGROUND: Rectal prolapse in young women is rare. Although laparoscopic ventral mesh rectopexy is the standard procedure because of its lower recurrence rate, postoperative infertility is a concern. Perineal rectosigmoidectomy (Altemeier procedure) is useful for these patients. However, the risk of anastomotic leakage should be considered. Recently, the usefulness of fluorescence imaging with indocyanine green (ICG) to prevent anastomotic leakage was reported. We report a case of an adolescent woman with complete rectal prolapse who underwent ICG fluorescence imaging-assisted Altemeier rectosigmoidectomy. CASE SUMMARY: A 17-year-old woman who had a mental disorder was admitted to our hospital for treatment for water intoxication. The patient also suffered from rectal prolapse, approximately 3 mo before admission. She was referred to our surgical department because recurrent rectal prolapse could worsen her psychiatric disorder. Approximately 10 cm of complete rectal prolapse was observed. However, the mean maximum anal resting and constriction pressures were within normal limits on anorectal manometry. Because she had the desire to bear children in the future, she underwent Altemeier perineal rectosigmoidectomy to prevent surgery-related infertility. We performed ICG fluorescence imaging at the same time as surgery to reduce the risk of anastomotic leakage. Her postoperative course was uneventful, and the rectal prolapse was completely resolved. She continued to do well 18 mo after surgery, without recurrence of the rectal prolapse. CONCLUSION: ICG fluorescence imaging-assisted Altemeier perineal rectosigmoidectomy is useful in preventing postoperative anastomotic leakage in young as well as elderly patients.

RESUMO

The current study reports the case of an 80-year-old woman who experienced severe hypoglycaemia after abemaciclib administration, with a recovery time of ~46 h. Abemaciclib is a cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor that is used to treat metastatic breast cancer. A side effect of abemaciclib administration is an increase in creatinine levels. The half-life (t1 / 2) of 150 mg abemaciclib in patients with breast cancer was reported to be 17.5 h (nearly lower limit), and the time to reach Cmax was ~5 h (Tmax, 4-6 h). Therefore, the total time to reach half the maximum blood concentration after abemaciclib administration is ~24 h (Tmax + t1 / 2=5+17.5=22.5 h). As abemaciclib is administered twice daily, a considerable amount (Cmax = 123 ng/ml) may persist in the blood following the initial dose. Upon repeated administration, the blood abemaciclib concentration in patients with metastatic liver tumours might increase, although their liver function remains normal. The patient described in the current study had a creatinine level of 1.05 mg/dl at the start of abemaciclib administration. At the time of emergency hospitalisation (on day 5 of abemaciclib administration), the creatinine level was 1.40 mg/dl; however, dehydration was not observed. The patient had been administered the same dose of glimepiride for >1 year and had not experienced hypoglycaemia previously. It can be speculated that the increase in blood creatinine level had some effect on glimepiride metabolism. It is thought that administered abemaciclib enhances metabolic delay in the blood in the same way as in patients with impaired liver function, and as a result, the creatinine level increases in patients with liver metastases. This causes a decrease in renal function, which in turn results in an increase in blood concentration of glimepiride, consequently leading to severe hypoglycaemia. Therefore, clinicians must be careful when using abemaciclib in patients with liver metastases, diabetes and poor renal function.

RESUMO

BACKGROUND: Inflammation influences cancer progression by increasing catabolism and impairing nutrient absorption. We compared the prognostic ability of three inflammation-based prognostic scoring systems-the Glasgow prognostic score (GPS), modified GPS (mGPS), and high-sensitivity mGPS (HS-mGPS)-in gastric cancer patients. MATERIALS AND METHODS: We retrospectively examined 434 curatively resected gastric cancer patients to evaluate the prognostic ability of scoring systems for overall survival (OS) and cancer-specific survival (CSS). RESULTS: OS analysis identified the following independent prognostic factors: GPS model: pathological stage (pStage, p < 0.001), carcinoembryonic antigen (CEA, p = 0.004), and GPS 1 (hazard ratio [HR], 1.929; 95% confidence interval [CI], 1.152-3.228; p = 0.013); mGPS model: body mass index (BMI, p = 0.027), pStage (p < 0.001), and CEA (p < 0.001); HS-mGPS model: BMI (p = 0.029), pStage (p < 0.001), and CEA (p = 0.003). mGPS and HS-mGPS were not independent prognostic factors for OS. CSS analysis of the GPS model identified pStage (p < 0.001), CEA (p = 0.015), and GPS 1 (HR; 2.095, 95% CI; 1.025-4.283; p = 0.043) and 2 (HR, 2.812; 95% CI, 1.111-7.116; p = 0.029) as independent prognostic factors; however, mGPS and HS-mGPS were not independent prognostic factors for CSS. Log-rank tests demonstrated significant differences in OS among patients with GPS 0 vs. 1 (p < 0.001) and 0 vs. 2 (p < 0.001) and in CSS among the three GPS (0 vs. 1; p = 0.005, 0 vs. 2; p < 0.001, 1 vs. 2; p = 0.009). CONCLUSIONS: GPS most reliably predicts long-term survival of gastric cancer patients.

RESUMO

The geriatric nutritional risk index (GNRI) is associated with mortality in several malignancies. We retrospectively analyzed whether the GNRI can predict long-term outcomes in 191 patients with esophageal squamous cell carcinoma (ESCC) after curative esophagectomies by evaluating their cancer-specific survival (CSS). In multivariate analyses, serum albumin (hazard ratio [HR], 2.498; p = 0.0043), GNRI (HR, 1.941; p = 0.0181), pathological tumor-node-metastasis (pTNM) stage (HR, 3.884; p < 0.0001), and tumor differentiation (HR, 2.307; p = 0.0066) were independent prognostic factors for CSS. In pTNM stage I, multivariate analysis identified C-reactive protein (HR, 7.172; p = 0.0483) and GNRI (HR, 5.579; p = 0.0291) as independent prognostic factors for CSS. In univariate analyses in pTNM stages II and III, only low GNRI (p = 0.0095) and low serum albumin levels (p = 0.0119), respectively, were significantly associated with worse CSS. In patients with low GNRI, CSS was significantly worse than in those with normal GNRI (p = 0.0011), especially in pTNM stages I (p = 0.0044) and II (p = 0.0036) groups, but not in stage III group (p = 0.5099). Preoperative GNRI may sort patients into low- or high-risk groups for shorter CSS, especially in those with pTNM stage I and II ESCC.

RESUMO

Aside from the induction of cell death, some anticancer chemotherapeutic drugs can modulate antitumor immune responses. In this study, we examined the anticancer effects of 5-fluorouracil (5-FU) and oxaliplatin (L-OHP), which are standard chemotherapeutic drugs for colon cancer, combined with cyclophosphamide (CP) in two mouse colon cancer models (CT26 and MC38 colon adenocarcinoma models). In the CT26 model, two injections of 5-FU/L-OHP and CP significantly suppressed the growth of subcutaneously established CT26 tumors compared with either 5-FU/L-OHP or CP, without a significant loss of body weight. The anticancer effect was weakened in nude mice. Cured mice acquired protective immunity against CT26, and CT26-specific cytotoxic T cells (CTLs) were induced from their spleen cells. Analysis of tumor-infiltrating immune cells revealed that 5-FU/L-OHP treatment with or without CP increased the proportion of CD8+ T cells at tumor sites. The 5-FU/L-OHP treatment decreased the proportion of granulocytic myeloid-derived suppressor cells (MDSCs) and increased monocytic MDSCs in tumor sites, whereas the addition of CP treatment reversed these changes. In the MC38 model, although significant anticancer effects of the triple combination therapy were seen, additional treatment with anti-PD-1 antibody increased the number of cured mice. These mice exhibited protective immunity against MC38, and MC38-specific CTLs were generated from their spleen cells. Together, these results indicate that the antitumor effects of the combination of 5-FU/L-OHP and CP mainly depend on host T cells; moreover, the therapeutic efficacy can be effectively boosted by immune checkpoint blockade.

RESUMO

BACKGROUND: The geriatric nutritional risk index (GNRI) was developed to evaluate the prognosis in elderly hospitalized patients at risk of malnutrition and related morbidity and mortality. This study aimed to evaluate the relationship between preoperative GNRI and long-term outcomes in elderly gastric cancer patients. MATERIALS AND METHODS: We retrospectively reviewed 297 consecutive patients aged ≥ 65 years who underwent laparoscopic gastrectomy with R0 resection and evaluated their overall survival (OS) and cancer-specific survival (CSS). RESULTS: In the univariate analyses, OS was significantly associated with the American Society of Anesthesiologists Physical Status (ASA-PS), tumor size, tumor differentiation, pathological stage, carcinoembryonic antigen (CEA), C-reactive protein, postoperative complications, and GNRI, whereas in the univariate analyses of CSS, ASA-PS, tumor size, tumor differentiation, pathological stage, CEA, postoperative adjuvant chemotherapy, and GNRI were significantly associated with poor prognosis. In the multivariate analysis, ASA-PS, tumor differentiation, pathological stage, and GNRI were significant independent prognostic factors of OS, whereas ASA-PS, pathological stage, and CEA were significant independent prognostic factors of CSS. CONCLUSIONS: GNRI is significantly associated with OS and CSS in elderly gastric cancer patients and is an independent predictor of OS. It is a simple, cost-effective, and promising nutritional index for predicting OS in elderly patients.

RESUMO

BACKGROUND: Red cell distribution width (RDW) is routinely assessed as part of the complete blood count (CBC) to gather information on the heterogeneity in the size of circulating erythrocytes. RDW is a more sensitive screening marker for anemia, inflammation, and nutritional deficiencies. The purpose of this study was to explore the prognostic value of RDW in esophageal squamous cell carcinoma (ESCC) patients. METHODS: We conducted a retrospective study of data from 148 ESCC consecutive patients who underwent potentially curative esophagectomy and analyzed the correlation of RDW with various clinicopathological factors. RESULTS: Multivariate analyses identified a high RDW (HR, 2.061; P = 0.0286) as a significant risk factor for cancer-specific survival (CSS). Kaplan-Meier analysis and the log-rank test demonstrated that patients with a high RDW had a significantly worse prognosis in terms of CSS than those with a low RDW (P = 0.0011). In multivariate analysis, there was no significant relationship between RDW and CSS in pathological tumor node metastasis stage I or II patients. However, a high RDW (HR, 2.386; P = 0.0471) was confirmed to be an independent worse prognostic factor for CSS in pathological tumor node metastasis stage III cancer patients. Kaplan-Meier analysis and the log-rank test showed a significant relationship between RDW and CSS in patients with pathological tumor node metastasis stage III (P = 0.0175). CONCLUSIONS: The RDW was a significant and independent predictor of poor survival in ESCC patients after curative esophagectomy. RDW may aid clinicians in detecting signs of recurrence very early and effectively customize treatment regimens. RDW is thus a convenient, cost-effective, and readily available biomarker to predict survival in ESCC.

RESUMO

BACKGROUND: We describe a novel scoring system, namely the inflammatory response biomarker (IRB) score. The aim of this study is to evaluate the clinical value of IRB score in patients undergoing curative resection for esophageal squamous cell carcinoma (SCC). METHODS: We retrospectively reviewed patients who underwent curative esophagectomy. We evaluated IRB score in both non-elderly (<70 years) and elderly (≥70 years) SCC patients. The IRB score was determined as follows: a high lymphocyte-to-monocyte ratio (LMR) (>4), a high neutrophil-to-lymphocyte ratio (NLR) (>1.6), and a low platelet-to-lymphocyte ratio (PLR) (<147) were each scored as 1, and the remaining values were scored as 0; the individual scores were then summed to produce the IRB score (range 0-3). RESULTS: Univariate analyses demonstrated that the TNM pStage (p < 0.0001), tumor size (p = 0.002), LMR (p = 0.0057), PLR (p = 0.0328) and IRB score (p = 0.0003) were significant risk factors for a worse prognosis. On multivariate analysis, the TNM pStage (p < 0.0001) and IRB score (p = 0.0227) were independently associated with worse prognosis in overall patients. Among non-elderly patients, multivariate analyses demonstrated that the pStage (p = 0.0015) and IRB score (p = 0.0356) were independent risk factors for a worse prognosis. Among elderly patients, multivariate analysis demonstrated that the pStage (p = 0.0016), and IRB score (p = 0.0102) were independent risk factors for a worse prognosis. CONCLUSION: The present study provides evidence that the preoperative IRB score can be considered a promising independent prognostic factor of cancer-specific survival in patients undergoing curative resection for SCC, and that its predictive ability is useful in both non-elderly and elderly patients.

RESUMO

A 27-year-old man with recurrent right lower quadrant pain was admitted to our hospital. Ultrasonography and computed tomography examination of the abdomen revealed a target sign in the ascending colon, which was compatible with the diagnosis of cecal intussusception. The intussusception was spontaneously resolved at that time, but it relapsed 6 mo later. The patient underwent a successful colonoscopic disinvagination; there was no evidence of neoplastic or inflammatory lesions in the colon and terminal ileum. The patient underwent laparoscopic surgery for recurring cecal intussusception. During laparoscopy, we observed an unfixed cecum on the posterior peritoneum (i.e. a mobile cecum). Thus, we performed laparoscopic appendectomy and cecopexy with a lateral peritoneal flap using a barbed wound suture device. The patient's post-operative course was uneventful, and he continued to do well without recurrence at 10 mo after surgery. Laparoscopic cecopexy using a barbed wound suture device is a simple and reliable procedure that can be the treatment of choice for recurrent cecal intussusception associated with a mobile cecum.

RESUMO

BACKGROUND: Systemic inflammatory markers, including the lymphocyte-to-monocyte ratio, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio have been shown to predict postoperative recurrence and survival in various types of cancer. However, their role in esophageal cancer has yet to be determined. This study aimed to evaluate the prognostic significance of an inflammatory response biomarker (IRB) score, independent of conventional clinicopathological criteria, in patients with esophageal cancer undergoing curative resection. PATIENTS AND METHODS: We retrospectively reviewed a database containing the medical records of 147 consecutive patients who underwent curative esophagectomy for esophageal squamous cell carcinoma. The IRB score was determined as follows: a low lymphocyte-to-monocyte ratio (<4), a low neutrophil-to-lymphocyte ratio (<1.6), and a high platelet-to-lymphocyte ratio (>147), which were each scored as 1, with all remaining values scored as 0. The scores were added together to produce the IRB score (range: 0-3). RESULTS: An IRB score of 2-3 (hazard ratio: 6.023, 95% confidence interval: 1.675-13.078; P<0.01) was identified as an independent poor prognostic factor of cancer-specific survival (CSS) in a multivariate logic regression analysis. The 5-year CSS rates in patients with the IRB scores of 0-1, 2, and 3 were 37.8%, 67.8%, and 72.5%, respectively. As determined by Kaplan-Meier analysis and the log-rank test, these differences were significant (P<0.001). CONCLUSION: The IRB score can predict the systemic inflammatory response as accurately as conventional tumor markers and is useful for determining CSS in patients with esophageal cancer undergoing curative thoracoscopic esophagectomy.
