The clinical impacts of the prognostic nutritional index for the esophageal cancer patients who received curative treatment.

BACKGROUND: We investigated the impact of the prognostic nutritional index (PNI) on esophageal cancer survival and recurrence after curative treatment. METHODS: This study included 120 patients who underwent curative surgery followed by the adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: The PNI of 49 was regarded to be the optimal critical point of classification considering the 1-year, 3-year, and 5-year survival rate. The OS rates at three and five years after surgery were 47.4% and 36.0% in the PNI low group, respectively, and 62.5% and 56.5% in the PNI high group, which amounted to a statistically significant difference ( P = 0.020). The RFS rates at three and five years after surgery were 31.0% and 24.8% in the PNI low group, respectively, and 50.9% and 42.8% in the PNI high group, which amounted to a statistically significant difference ( P = 0.020). A multivariate analysis demonstrated that the PNI was a significant independent risk factor for the OS and a marginally significant independent risk factor forRFS. CONCLUSION: The PNI was a risk factor for survival in patients who underwent curative treatment for esophageal cancer. It is necessary to develop the effective plan of the perioperative care and the surgical strategy according to the PNI.

Geriatric Nutritional Risk Index Is an Independent Prognostic Factor for Patients With Esophageal Cancer Who Receive Curative Treatment.

BACKGROUND/AIM: The perioperative nutritional status has recently been reported to influence the prognosis of various types of cancer. We investigated the relationship between the Geriatric Nutritional Risk Index (GNRI) and overall survival (OS) and recurrence-free survival (RFS) in patients with esophageal cancer who received radical and adjuvant therapy. PATIENTS AND METHODS: Patients who underwent radical resection for esophageal cancer at our hospital (n=187) were included. Background characteristics, surgical factors, and OS were examined retrospectively. The GNRI was calculated using preoperative values, with GNRI <98 classified as low-GNRI. RESULTS: Seventy-five and 112 patients were classified into the GNRI-low and -high groups, respectively. The 3- and 5-year OS rates were 75.7% and 66.7%, respectively, in the GNRI-high group and 43.2% and 36.7% in the GNRI-low group; the difference was statistically significant (p<0.001). In the univariate and multivariate analyses, low-GNRI was selected as a risk factor for OS. The hazard ratio for low-GNRI was 2.184 (95% confidence interval=1.361-3.508, p=0.001). The 5-year RFS rate in the high- and low-GNRI groups was 54.6% and 25.0%, respectively (p=0.001). In the univariate and multivariate analyses, low-GNRI was a risk factor for RFS. The hazard ratio for low-GNRI was 1.704 (95%CI=1.121-2.590, p=0.013). Regarding the type of recurrence, lymph node recurrence was significantly more common in the low-GNRI group (p=0.008). CONCLUSION: Low-GNRI was an independent risk factor for OS and RFS after radical resection of esophageal cancer. The preoperative GNRI may be a useful prognostic factor after esophageal cancer surgery.

The Clinical Influence of Geriatric Nutritional Risk Index in Patients With Gastric Cancer Who Receive Curative Treatment.

BACKGROUND/AIM: We evaluated the clinical impact of the Geriatric Nutritional Risk Index (GNRI) in patients who received curative treatment and perioperative adjuvant treatment. We also investigated the association between the GNRI and the clinicopathological features of patients with GC. PATIENTS AND METHODS: This study included 280 patients who underwent curative treatment for GC between 2005 and 2020. The prognosis and clinicopathological parameters of the high-GNRI and low-GNRI groups were compared. RESULTS: In the GNRI-high group, the overall survival (OS) rates at 3 and 5 years after surgery were significantly lower (82.7% and 77.9%, respectively) than those in the GNRI-low group (56.4% and 40.8%). The GNRI was selected for the final multivariate analysis model for OS. The GNRI was also a significant prognostic factor for recurrence-free survival (RFS). The RFS rates at 3 and 5 years after surgery were 79.1% and 74.8%, respectively, in the GNRI-high group, and 48.0% and 38.6% in the GNRI-low group. The GNRI was selected for the final multivariate analysis model for RFS. The GNRI was also found to affect the postoperative clinical course, including postoperative surgical complications and postoperative adjuvant chemotherapy. CONCLUSION: The GNRI may be a promising prognostic and predictive factor for gastric cancer. In the future, the GNRI may be used to select optimal treatment strategies.

Clinical Impact of Nutrition and Inflammation Assessment Tools in Pancreatic Cancer Treatment.

Perioperative adjuvant treatment and complete resection is the standard treatment for resectable pancreatic cancer and systemic chemotherapy is standard treatment for unresectable pancreatic cancer. To improve the survival of patients with pancreatic cancer, it is necessary to identify promising biomarkers to optimize the treatment. The availability of biomarkers may allow patients to receive a more aggressive or less toxic treatment. Recent studies showed that the inflammatory and nutritional status perioperatively and/or during chemotherapy affect short and long-term oncological outcomes in pancreatic cancer. Introduction of inflammatory and nutritional status evaluation in pancreatic cancer treatment might improve the postoperative surgical complications or chemotherapy-induced adverse events. However, to introduce these various nutritional and inflammation assessment tools in daily clinical practice, it is necessary to understand the characteristics of each nutrition and inflammation assessment tool. This review summarizes the background, current status, and future perspectives of nutrition and inflammation assessment tools in pancreatic cancer treatment.

Clinical Course of Vitamin B12 Deficiency and Associated Risk Factors in Patients After Total Gastrectomy for Gastric Cancer.

BACKGROUND/AIM: Patients are at-risk for vitamin B12 deficiency after total gastrectomy due to a lack of intrinsic factors. The aim of the study was to clarify the clinical course and risk factors for vitamin B12 deficiency after total gastrectomy for gastric cancer patients. PATIENTS AND METHODS: Patients who underwent curative resection for gastric cancer were selected from the medical records of the Yokohama City University from 2000 to 2020. A logistic regression analysis was performed to identify risk factors for vitamin B12 deficiency. RESULTS: We evaluated 47 patients. The median serum vitamin B12 levels before surgery were 359 pg/ml, while those at 3, 6, 9, and 12 months after surgery these were 255 pg/ml, 197.5 pg/ml, 195 pg/ml, and 206 pg/ml, respectively. Univariate analyses to identify factors associated with vitamin B12 deficiency at 6 months after surgery showed that the occurrence of postoperative complications was a significant risk factor (OR=6.347, 95%CI=1.607-25.774, p=0.009), while adjuvant chemotherapy was a marginally significantly risk factor (OR=3.562, 95%CI=0.877-14.477, p=0.076). CONCLUSION: Almost half of the patients were diagnosed with vitamin B12 deficiency at 6 months after total gastrectomy for gastric cancer. In addition, the occurrence of postoperative complications and adjuvant chemotherapy were risk factors for vitamin B12 deficiency at 6 months after surgery.

The Albumin-Bilirubin Score Is a Prognostic Factor for Gastric Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: The albumin-bilirubin (ALBI) score is a promising tool for the evaluation of the perioperative hepatic function. The present study aimed to evaluate the clinical impact of the preoperative ALBI status in patients with gastric cancer (GC) who received curative treatment. PATIENTS AND METHODS: The present study included 244 patients who underwent curative treatment for GC between 2005 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: Based on the 3- and 5-year OS rates, we set the cut-off value for the ALBI score at -2.7849. The 3- and 5-year OS rates were 87.3% and 80.9%, respectively, in the ALBI-low group, and 66.9% and 60.6% in the ALBI-high group; these differences were statistically significant (p<0.001). The ALBI score was included in the final multivariate analysis model [Hazard ratio (HR)=2.120, 95% confidence interval (CI)=1.177-3.818, p=0.012]. Similar results were observed for RFS. In addition, the ALBI score correlated with the introduction of postoperative adjuvant chemotherapy. CONCLUSION: The preoperative ALBI score correlated with both the OS and RFS of GC patients as well as the clinical course of adjuvant chemotherapy. Taken together, the ALBI score is a promising prognostic factor for GC.

Clinical Impact of Preoperative Albumin-Bilirubin Status in Esophageal Cancer Patients Who Receive Curative Treatment.

BACKGROUND/AIM: The albumin-bilirubin (ALBI) score, which evaluates the perioperative liver function, was developed, and had a clinical impact on both the short- and long-term oncological outcomes in some malignancies. We evaluated the clinical impact of preoperative albumin-bilirubin status in patients with resectable esophageal cancer who received curative treatment. PATIENTS AND METHODS: The study included 121 patients who underwent curative surgery followed by adjuvant chemotherapy for esophageal cancer between 2005 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. RESULTS: Based on the 3- and 5-year OS rates, we set the cut-off value for the ALBI score at -2.7. Eighty patients were classified into the ALBI-low group (ALBI score <-2.7), 41 patients were categorized into the ALBI-high group (ALBI score >-2.7). The 3- and 5-year OS rates were 62.2% and 53.2%, respectively, in the ALBI-low group, and 42.2% and 35.2% in the ALBI-high group. There was a significant difference in OS (p=0.0113). The 3- and 5-year RFS rates were 43.1% and 40.3%, respectively, in the ALBI-low group and 37.7% and 26.1% in the ALBI-high group. There was a significant difference in RFS (p=0.048). When comparing the perioperative clinical course between the ALBI-high and ALBI-low groups, the incidence of postoperative anastomotic leakage was 46.3% (19/41) in the ALBI-high group, and 27.5% (22/80) in the ALBI-low group (p=0.038). CONCLUSION: The ALBI status had a clinical impact on both OS and RFS in esophageal cancer patients. Therefore, ALBI may have potential application as a prognostic factor for esophageal cancer patients.

Clinical Significance of Glioma-associated Oncogene 1 Expression in Patients With Locally Advanced Gastric Cancer Administered Adjuvant Chemotherapy With S-1 After Curative Surgery.

BACKGROUND/AIM: Glioma-associated oncogene 1 (GLI1) is an important transcription factor in the hedgehog signalling pathway and tumour formation. We evaluated the clinical significance of GLI1 expression as a prognostic factor in patients with locally advanced gastric cancer (GC). PATIENTS AND METHODS: GLI1 expression levels were measured by quantitative real-time polymerase chain reaction analysis of cancerous and adjacent normal mucosa specimens obtained from 142 patients with Stage II/III GC administered adjuvant chemotherapy with S-1 after curative resection. The associations of GLI1 expression with clinicopathological features and survival were evaluated. RESULTS: Clinicopathological features and GLI1 expression showed no association. Overall survival was significantly poorer in the high compared to the low GLI1 expression group (p=0.04). Multivariate analysis revealed that GLI1 expression was a significant independent prognostic factor [p=0.019, hazard ratio (HR)=1.94, 95% confidence interval (CI)=1.70-3.38]. CONCLUSION: GLI1 expression may be a useful prognostic marker in patients with locally advanced GC.

[A Case of Sigmoid Colon Cancer Accompanied by Intestinal Malrotation Treated by Laparoscopic Surgery].

A 52-year-old man whose fecal occult blood test was positive was found to have type 2 sigmoid colon cancer by colonoscopy. On enhanced barium enema study, the cecum was in the pelvis, and the ascending colon was running medially in the abdomen. Enhanced CT scan of the abdomen revealed rotation of the superior mesenteric vein(SMV). We diagnosed the case as sigmoid colon cancer(cT3N0M0, StageⅡA)with non rotation-type intestinal malrotation, and performed laparoscopic surgery. We confirmed the small intestine to be located on the right side of the abdomen, the cecum to be located in the pelvis, and the ascending colon to be running medially in the abdomen. The ascending mesocolon was adherent to the right of the sigmoid mesocolon. Following dissections of the ascending mesocolon from the sigmoid mesocolon, we performed surgery via the inside approach as usual. We dissected the root of the inferior mesenteric artery(IMA), and the operation was completed. In laparoscopic surgery for colorectal cancer with intestinal malrotation, there are some reports that it could be performed safely if attention is paid to adhesion of the mesenteries and vascular variation in the course of preoperative imaging diagnosis. We report a case of laparoscopic surgery that could be safely performed for sigmoid colon cancer with non rotation-type intestinal malrotation.

Randomized phase II study of TJ-54 (Yokukansan) for postoperative delirium in gastrointestinal and lung malignancy patients.

The present study evaluated the efficacy and safety of TJ-54 (Yokukansan; a traditional Japanese medicine) for the prevention and/or treatment of postoperative delirium in a randomized phase II trial of patients receiving surgery for gastrointestinal and lung malignancies. Patients ≥70 years of age who underwent surgery for gastrointestinal or lung malignancy were eligible for participation in the study. The 186 eligible patients were randomly assigned at a 1:1 ratio to receive TJ-54 or control during their peri-operative care (between 7 days prior to surgery and 4 days following surgery, except for the operation day). The signs and symptoms of delirium were assessed using the Diagnostic and Statistical Manual of Mental Disorders-IV by the investigator during the peri-operative period. A total of 186 eligible gastrointestinal or lung malignancy patients were analyzed (93, TJ-54; 93, control). There were no marked differences between the two randomized groups. The incidence of delirium was 6.5% (6 patients) in the TJ-54 group and 9.7% (9 patients) in the control group, with no significant difference (P=0.419). However, of the patients categorized with a mini-mental state examination (MMSE) score of ≤26, the incidence of postoperative delirium was 9.1% in the TJ-54 group and 26.9% in the control group [risk ratio, 0.338; 95% confidence interval (0.078-1.462), P=0.115]. Treatment with TJ-54 reduced the incidence of postoperative delirium compared with the control group. Although TJ-54 did not demonstrate any contribution to preventing or treating postoperative delirium in patients following surgery for gastrointestinal or lung malignancy, TJ-54 reduced the risk of postoperative delirium in the patients who were classified as MMSE ≤26. Further phase III studies with a larger sample size are required in order to clarify the effects of TJ-54 against postoperative delirium.

Does herbal medicine reduce the risk of hepatocellular carcinoma?

Many herbal medicines are effective anti-inflammatory agents and may therefore suppress the development of hepatocellular carcinoma (HCC). Recently, treatment with a single-tablet regimen containing ledipasvir and sofosbuvir resulted in high rates of sustained virologic response among patients with hepatitis C virus genotype 1 infection who did not respond to prior interferon-based treatment. Patients with chronic hepatitis C are expected to receive this treatment worldwide. However, many patients have hepatitis-like fatty liver and nonalcoholic steatohepatitis. A strategy to prevent the development of HCC in this subgroup of patients is urgently required. Whether herbal medicines can suppress the development of HCC remains to be established. However, herbal medicines are effective anti-inflammatory agents and may inhibit the development of HCC. Clinical trials exploring the effectiveness of herbal medicines in the prevention and treatment of HCC are therefore warranted. The current lack of knowledge and of educational programs is a barrier to increasing the use of potentially effective herbal medicines and performing prospective clinical trials.

[Outcomes of laparoscopic surgery after preoperative metallic stent placement for obstructive colorectal cancer].

AIM: To assess the outcomes of preoperative colonic stent placement for obstructive colorectal cancer. PATIENTS AND METHODS: A total of 30 patients with colorectal cancer were treated after preoperative colonic metallic stent placement between July 2012 and March 2014. We reviewed their medical records to assess the usefulness of stent placement and the clinical course. The effects of various clinicopathological variables on post-operative complications were analyzed statistically. RESULTS: Stent insertion was effective in 93% of the 30 patients with obstructive colorectal cancer. Preoperative colonoscopy or enema for proximal colonic survey was possible in 70% of the patients after stent placement; colonic lesions requiring simultaneous resection were noted in 5 patients (24%). The mean interval between stent insertion and operation was 19 days, and 23%of the patients underwent laparoscopic surgery. Statistical analysis revealed that the occurrence of complications was associated with laparoscopic surgery and the amount of operative blood loss. CONCLUSION: Preoperative stent placement in patients with obstructive colorectal cancer is feasible and laparoscopic surgery can be selected after stent placement.

[Effect of enteral nutrition enriched with eicosapentaenoic acid on body weight loss and compliance with S-1 adjuvant chemotherapy after gastric cancer surgery].

BACKGROUND: Eicosapentaenoic acid-enriched oral nutritional supplements (Prosure®; Abbott Japan, Tokyo, Japan) may attenuate surgical stress and catabolism after gastric cancer surgery. The present study aimed to evaluate the effects of Prosure® on body weight loss( BWL) and compliance with S-1 adjuvant chemotherapy after gastrectomy. PATIENTS AND METHODS: Patients who underwent curative total gastrectomy for gastric cancer were selected to undergo adjuvant S-1 chemotherapy at Kanagawa Cancer Center between December 2010 and October 2011. The patients received a normal postgastrectomy diet and two 240 mL packs of Prosure® for 21 postoperative days. BWL was defined as %BWL and calculated as %BWL=(preoperative body weight-1-month postoperative body weight)×100/preoperative body weight. Time to S-1 treatment failure was calculated. RESULTS: Five patients were enrolled in this study. The median age was 62.0 years. One patient was male, and 4 were female. The 1-month postoperative BWL was 92.1%. Compared to our previous report, a 20% risk reduction was observed in this study (Prosure® group vs control group, 92.1% vs 89.7%). Moreover, all the patients continued with the S-1 adjuvant chemotherapy for longer than 6 months. CONCLUSION: Prosure® may inhibit BWL at 1 month after gastrectomy. Moreover, Prosure® improved the patients' compliance with the adjuvant chemotherapy after gastrectomy.

The clinicopathological features of colorectal mucinous adenocarcinoma and a therapeutic strategy for the disease.

BACKGROUND: The guidelines established by the National Comprehensive Cancer Network do not describe mucinous histology as a clinical factor that should influence the therapeutic algorithm. However, previous studies show conflicting results regarding the prognosis of colorectal mucinous adenocarcinoma. In this study, we described the clinicopathological features of mucinous adenocarcinoma in Japan, to identify optimal therapeutic strategies. METHODS: 144 patients with mucinous and 2673 with non-mucinous adenocarcinomas who underwent primary resection in two major centers in Yokohama, Japan were retrospectively evaluated for clinicopathological features and treatment factors. A multivariate analysis for overall survival followed by the comparison of overall survival using Cox proportional hazard model were performed. RESULTS: Patients with mucinous adenocarcinoma had larger primary lesions, higher preoperative CEA levels, a deeper depth of invasion, higher rates of nodal and distant metastasis, and more metastatic sites. A multivariate analysis for overall survival revealed a mucinous histology to be an independent prognostic factor. In the subgroup analysis stratified by stage, Patients diagnosed as stageIII and IV disease had a worse survival in mucinous adenocarcinoma than non-mucinous, while survival did not differ significantly in patients diagnosed as Stage0-II disease. In stageIII, local recurrence in rectal cases and peritoneal dissemination were more frequently observed in patients with a mucinous histology. CONCLUSIONS: Our study indentified that mucinous adenocarcinoma was associated with a worse survival compared with non-mucinous in patients with stageIII and IV disease. In rectal StageIII disease with mucinous histology, additional therapy to control local recurrence followed by surgical resection may be a strategical alternative. Further molecular investigations considering genetic features of mucinous histology will lead to drug development and better management of peritoneal metastasis.

Usefulness of multidisciplinary therapy combining neoadjuvant chemotherapy with S-1 plus cisplatin and postoperative sequential chemotherapy in patients with scirrhous gastric cancer.

BACKGROUND/AIMS: The outcomes of patients with scirrhous gastric cancer (SGC) remain poor. We retrospectively compared outcomes according to historically different treatments for SGC and studied the therapeutic usefulness of NAC with S-1 plus cisplatin followed by postoperative sequential chemotherapy. METHODOLOGY: We studied 93 patients with SGC. Between 1995 and 2000, 29 patients did not receive NAC and were instead given conventional anti-cancer drugs. Between 2000 and 2003, 20 patients received 4 weeks of NAC with low-dose cisplatin plus 5-fluorouracil (5-FU) followed by postoperative sequential treatment with new anticancer agents (neoadjuvant low-dose FP group). Between 2003 and 2006, 44 patients received 2 courses of NAC with S-1+cisplatin followed by postoperative sequential administration of new anticancer agents (neoadjuvant S-1+cisplatin group). Response rates and overall survival were compared among the treatment groups. RESULTS: The rates of response to NAC were 15% in the neoadjuvant low-dose FP group and 36% in the neoadjuvant S-1+cisplatin group. Overall survival was significantly longer in the neoadjuvant S-1+cisplatin group than the other groups. CONCLUSIONS: Our results suggest that multidisciplinary therapy combining NAC with S-1+cisplatin and postoperative sequential administration of new anticancer drugs is therapeutically useful in patients with SGC.

[Modified FOLFIRI (l-LV, 5-fluorouracil and irinotecan) therapy for Japanese patients with metastatic colorectal cancer].

PURPOSE: As a project of the Kanagawa Colorectal Cancer Study Group, we performed this study to analyze the efficacy and the safety of modified FOLFIRI (irinotecan: 150 mg/m2) therapy for Japanese patients with metastatic colorectal cancer. PATIENTS AND METHODS: We treated PS 0-1 Japanese patients with measurable or assessable colorectal cancer who either had not received preliminary treatment, or were postoperative with metastasis and had undergone radiation therapy or adjuvant chemotherapy before more than four weeks, and further had provided written acceptance of our proposed procedures. Twenty patients received modified FOLFIRI therapy as a 2-hour infusion of CPT-11 150 mg/m/2 and l-LV 200 mg/m2 followed by a bolus 5-FU 400 mg/m/2 and 46-hour infusion 5-FU 2, 400 mg/m2. Tumor response was assessed by RECIST and toxicity by NCI-CTC. RESULTS: Thirty males and seven females underwent an average 10 courses of treatment. This therapy achieved a 50% response rate, 80%disease-control rate, and 316+/-40 days PHS. Regarding hematological toxicity, 11 patients (55%) experienced leukemia, which developed to grade 3/4 in 5 (25%) of them. Twelve patients (65%) experienced neutropenia, which developed to grade 3/4 in 10 (50%) of them. Digestive toxicity was observed in 16 patients (80%), which developed to grade 3/4 in only one patient (5%) with gastric ulcer. Six patients (30%) experienced alopecia, which was grade 1/2 only. CONCLUSION: This clinical study was safely carried out. The efficacy was as good as in previous reports using a regular dose of CPT-11.

Penetration of the sigmoid colon to the posterior uterine wall secondary to diverticulitis: a case report.

INTRODUCTION: Penetration of the colon to the posterior uterine wall secondary to diverticulitis is unusual, with diagnostic methods not yet established. Non-invasive imaging, such as computed tomography and magnetic resonance imaging may help to establish a proper diagnosis, but confirmation may be reached only after surgical exploration. CASE PRESENTATION: We report the case of a 78-year-old Japanese woman who presented with a low grade fever and mild diarrhea which occurred two or three times a week. Computed tomography and magnetic resonance imaging demonstrated a capsular lesion including an air structure with a diameter of 5 cm, between the posterior aspect of the uterine body and the sigmoid colon. A gastrograffin enema and colonoscopy demonstrated a giant diverticulum of the sigmoid colon with no evidence of malignancy. These data confirmed the diagnosis of diverticulitis complicated by a giant diverticulum. Because of a relapsing fever after therapy with antibiotics, the patient had en bloc surgical treatment of the uterus, fallopian tubes, ovaries and sigmoid colon, the organs involved in the diverticulitis, followed by an uneventful recovery. CONCLUSION: This is a rare case report of penetration of the sigmoid colon to the posterior uterine wall secondary to diverticulitis.

Reduction therapy of alanine aminotransferase levels prevent HCC development in patients with HCV-associated cirrhosis.

BACKGROUND: To find a way to prevent the development of hepatocellular carcinoma (HCC) from hepatitis C virus-associated liver cirrhosis (HCV-LC), an analysis of the HCV-LC patients who had received reduction therapy of the alanine aminotransferase (ALT) levels was performed. PATIENTS AND METHODS: Seventy-four consecutive HCV-LC patients of Child Stage A were followed for >10 years for the development of HCC. They were divided into two groups: in group A, the reduction therapy for the ALT levels was aggressively performed, while in group B, the reduction therapy was not performed aggressively. The patients were subdivided into three sub-groups according to their serum ALT levels. In groups A and B, the high ALT group was comprised, respectively, of nine and five patients whose annual average serum ALT levels were persistently high (> or =80 IU), while the low ALT group was comprised of 19 and 20 patients whose annual average serum ALT levels were persistently low (<80 IU). The remaining eleven and ten patients had annual average serum ALT levels which fluctuated and were unclassified (unclassified group). RESULTS: In group B, 65.7% of the patients had developed HCC in 13 years, in contrast to only 41.0% of group A (p=0.039). In group A, the median HCC development time was 12.8 years, in contrast to only 3.8 years in group B (p=0.0013). Multivariate analysis demonstrated that the mode of reduction therapy and ALT levels were the significant factors affecting HCC development. CONCLUSION: The chances of surviving for more than ten years without developing HCC for HCV-LC patients

A case of primary mesenteric embryonal carcinoma.

We describe a case of primary mesenteric embryonal carcinoma. The patient was a 73-year-old man who presented with a huge mass palpable at the right upper side of the abdomen. Laboratory evaluations showed very high alpha-fetoprotein and PIVKA-II levels, and an abdominal computed tomographic scan demonstrated a mass contiguous with the liver. These findings suggested hepatic cell carcinoma extending beyond the liver. However, angiography showed the mass to be supplied mainly by the middle colic artery and greater omentum artery, suggesting a mesenteric tumor. Gastroscopy demonstrated a IIc lesion in the anterior wall of the antrum. This lesion was histologically diagnosed to be moderately differentiated adenocarcinoma. The large tumor adjacent to the liver was diagnosed to be a primary mesenteric tumor or a metastatic mesenteric tumor from arising gastric cancer. At laparotomy, a huge tumor was found in the gastrocolic ligament. The tumor adhered to the distal part of stomach, the transverse colon, and the gallbladder. En-bloc resection of the tumor was performed, including the distal part of stomach, Part of the transverse colon, and the gall-bladder. The tumor mass measured 26.0 x 21.0 x 9.0 cm, weighted 2750 g, and showed central necrosis and hemorrhage. The histopathological diagnosis was a primary embryonal carcinoma originating in the mesentery. Primary mesenteric embryonal carcinoma is extremely rare. To our knowledge, no other cases have been reported. We describe this case and briefly discuss the related literature.

Autologous salvaged blood transfusion in spontaneous hemopneumothorax.

Spontaneous hemopneumothorax (SHP) is a rare clinical entity, and an emergent operation due to continuous bleeding or hypovolemic shock is at times necessary. Although allogeneic blood transfusions are urgently required for significant blood loss, autologous blood transfusions can also be considered in patients with SHP. We herein report two cases of successful autologous blood transfusions using blood in the pleural space, decreasing or obviating the need for allogeneic blood transfusion.
