Objective To evaluate the diagnostic and therapeutic methods for hilar bile duct carcinoma. Methods The clinical data of 36 patients with hilar bile duct carcinoma from Jan 1998 to Jul 2003 were retrospectively analyzed. Results The misdiagnosis rate(39%) was high. All patients underwent a surgery. The median survival time of 16 patients treated by radical resection was 30 months. The 1,3,5-year survival rate was 93%,50% and 25% respectively. While the median survival time of the rest 20 patients treated by a variety of non-radical operation was 16 months with 1,3,5-year survival rate of 47%,8% and 0 respectively(t=2.585).Conclusions Early diagnosis and radical resection improves long-term survival of patients with hilar bile duct carcinoma.

Fifteen tissues of 4-year-old fruit repining stage Jilin ginseng were chosen as materials, six kinds of monomer saponins (ginsenosides Rg1, Re, Rb1, Rc, Rb2 and Rd) content in 15 tissues was measured by HPLC and vanillin-sulfuric acid method. The relative expression of FPS, SQS, SQE, OSC, β-AS and P450 genes in 15 tissues was analyzed by real-time PCR. The correlations between ginseng saponin content in 15 tissues of Jilin ginseng and biosynthetic pathway -related genes were obtained. The results showed that was a synergistic increase and decrease trend of positive linear correlation among six kinds of monomer saponin content, and there was a significantly (P < 0.01) positive correlation between monomer saponin content and total saponins content. Monomer saponin content and 6 kinds of enzyme gene correlation were different. Biosynthesis of ginseng total saponins and monomer saponin were regulated by six kinds of participation ginsenoside biosynthesis enzyme genes, the expression of these six kinds of genes in different tissues of ginseng showed collaborative increase and decrease trend, and regulated biosynthesis of ginseng ginsenoside by group coordinative manner.

OBJECTIVETo investigate the role of silencing PRL-3 expression by miRNA interference in gastric cancer growth.

METHODSRNA interference mediated by recombinant lentivirus expressing artificial PRL-3 miRNA was employed to knockdown PRL-3 expression in human SGC7901 gastric cancer cells. MTT assay and tumor implantation experiment were conducted to determine the role of PRL-3 in the proliferation of SGC7901 cells and the tumor growth.

RESULTSTransfection of recombinant lentivirus expressing artificial PRL-3 miRNA significantly suppressed the proliferation of SGC7901 cells in vitro. The implanted tumor size of the PRL-3 transfection group was (1.92 +/- 0.18) cm3, significantly smaller than those in control groups [(4.74 +/- 0.39) cm3] (P < 0.05).

CONCLUSIONSSilencing of PRL-3 significantly suppressed the proliferation of SGC7901 cells and tumor growth in vivo. PRL-3 could be a potential therapeutic target in gastric cancer.

OBJECTIVETo evaluate the impact of different gastrectomy and reconstruction method on prognosis and quality of life in proximal gastric cancer.

METHODSThe 265 cases of proximal gastric cancer received radical resection, according to gastrectomy or reconstruction method, were divided into proximal gastrectomy/gastroesophagostomy group (PG) (n = 63) and total gastrectomy/esophagojejunostomy group (TG) (n = 202). The clinical pathologic features, prognosis, postoperative quality of life in 2 groups were compared.

RESULTSThere had no significant differences in age, gender, CEA value between two groups (all P > 0.05). In PG and TG group, tumor size (cm), ratio of organic invasion, lymph nodes metastasis, distal metastasis, TNM IV stage, Borrmann typing, poor or undifferentiated carcinoma was 2.9 ± 1.9 vs. 4.8 ± 2.8, 9.5% vs. 32.2%, 64.7% vs. 70.6%, 0 vs. 8.4%, 6.9% vs. 31.8%, 44.4% vs. 69.2%, 31.7% vs. 53.7%, respectively, all with significant difference (t = -6.260, χ(2) = 29.473, 14.559, 5.665, 32.483, 12.588, 10.954, all P < 0.05). In PG and TG group, the ratio of D3 and D3(+) resection, multi-visceral resection, complications was 0 vs. 13.8%, 9.5% vs. 38.6%, 7.9% vs. 1.5% respectively, showed increasing range of resection and decreasing complications significantly in TG group (all P < 0.05). The median survival time (months) was 62.5 vs. 78.9 in TG and PG group respectively, without significant difference (P > 0.05). In 2 groups, the evaluation index of post-operative quality of life without significant differences (P > 0.05).

CONCLUSIONSFor proximal gastric cancer, although the cases received TG with worse clinicopathological features, which prognosis was similar to that received PG. The postoperative quality of life without significant difference between the cases received gastroesophagostomy and esophagojejunostomy.

OBJECTIVETo investigate the clinicopathological characteristics between mucinous gastric cancer (MGC) and poorly differentiated gastric cancer(PDGC) and factors associated with prognosis.

METHODSMedical records of 1016 consecutive patients with gastric cancer were retrospectively reviewed. Sixty-eight patients with MGC and 508 with PDGC were identified. Clinicopathologic characteristics and overall survival data were analyzed.

RESULTSAs compared to PDGC patients, patients with MGC were significantly older [(59.2±11.9) years vs. (54.1±13.2) years], had significantly more distant metastasis(36.8% vs. 23.8%), more peritoneal seeding(29.4% vs. 16.9%), and less radical resection(60.3% vs. 76.6%). There were no significant differences in 5-year survival rate between MGC and PDGC patients(29.4% vs. 35.5%). However, for tumors in the middle third of the stomach, the survival rate of MGC patients was lower than that of PDGC. Using a Cox proportional hazard ratio model, lymph node involvement and radical resection were independent prognostic factors for survival of MGC patients, while tumor invasion, lymph node involvement, and radical resection were associated with survival in patients with PDGC.

CONCLUSIONAlthough MGC and PDGC differ in age, frequencies of peritoneal seeding, distant metastasis, and rate of radical resection, overall survival is comparable.

BACKGROUNDPancreaticogastrostomy (PG) has been proposed as an alternative to pancreaticojejunostomy (PJ), assuming that postoperative complications are less frequent. The aim of this research was to compare the safety of PG with PJ reconstruction after pancreaticoduodenectomy.

METHODSArticles of prospective controlled trials published until the end of December 2010 comparing PJ and PG after PD were searched by means of MEDLINE, EMBASE, Cochrane Controlled Trials Register databases, and Chinese Biomedical Database. After quality assessment of all included prospective controlled trials, meta-analysis was performed with Review Manager 5.0 for statistic analysis.

RESULTSOverall, six articles of prospective controlled trials were included. Of the 866 patients analyzed, 440 received PG and 426 were treated by PJ. Meta-analysis of six prospective controlled trials (including RCT and non-randomized prospective trial) revealed significant difference between PJ and PG regarding postoperative complication rates (OR, 0.53; 95%CI, 0.30 - 0.95; P = 0.03), pancreatic fistula (OR, 0.47; 95%CI, 0.22 - 0.97; P = 0.04), and intra-abdominal fluid collection (OR, 0.42; 95%CI, 0.25 - 0.72; P = 0.001). The difference in mortality was of no significance. Meta-analysis of four randomized controlled trials (RCT) revealed significant difference between PJ and PG regarding intra-abdominal fluid collection (OR, 0.46; 95% CI, 0.26 - 0.79; P = 0.005). The differences in pancreatic fistula, postoperative complications, delayed gastric emptying, and mortality were of no significance.

CONCLUSIONSMeta-analysis of six prospective controlled trials (including randomized controlled trials (RCT) and non-randomized prospective trial) revealed significant difference between PJ and PG regarding overall postoperative complications, pancreatic fistula, and intra-abdominal fluid collection. Meta-analysis of four RCT revealed significant difference between PJ and PG with regard to intra-abdominal fluid collection. The results suggest that PG may be as safe as PJ.

OBJECTIVETo explore the expression of serine protease Omi/HtrA2 in gastric carcinoma tissue and its association with clinicopathological features and prognosis.

METHODSOmi/HtrA2 protein expression levels were detected by immunohistochemistry method in resected gastric carcinomas(n=68), adjacent noncancerous tissues(n=15), and normal tissues(n=15), and its association with clinicopathological features and prognosis were analyzed.

RESULTSOmi/HtrA2 expression was positive in 73.5%(50/68) of gastric cancer tissues, which was significantly higher than that in adjacent noncancerous tissues and normal tissues(P<0.05). There were no significant differences in Omi/HtrA2 expression with respect to sex, age, tumor size, and depth of invasion(all P>0.05). Omi/HtrA2 expression level was significantly associated with tumor differentiation, extent of lymph node metastasis, and tumor stage(all P<0.05). Overall 5-year survival rate of patients with gastric carcinoma was 63.3%. Five-year survival rate was higher in Omi/HtrA2 positive cases than Omi/HtrA2 negative cases(72.0% vs. 61.1%), however the difference was not statistically significant.

CONCLUSIONSOmi/HtrA2 expression is more common in gastric carcinoma. Omi/HtrA2 expression is associated with tumor differentiation, extent of lymph node metastasis, and tumor stage.

OBJECTIVETo investigate the clinicopathologic features, diagnosis and treatment of neuroendocrine carcinoma (NEC) in the digestive system.

METHODSThirty-eight patients with NEC from Jan 1985 to Mar 2008 were analyzed retrospectively and the related literatures were reviewed.

RESULTSThere were 29 males and 9 females. Common symptoms were melena or hematochezia (n=21, 55%), abdominal pain (n=19, 50%), abdominal mass (n=15, 39%), constipation (n=14, 37%), rectal mass (n=12, 32%), abdominal distention (n=11,29%) and diarrhea (n=7,18%). All the patients received surgical treatment including 1 esophagectomy, 5 radical total gastrectomies, 1 palliation proximal gastric resection, 2 local gastric resections, 6 pancreaticoduodenectomies, 1 distal pancreatectomies, 3 partial small intestine resections, 7 radical right hemicolectomies, 5 Dixon operations, 3 Miles operations, and 4 local resections of rectal tumor. Thirty-six patients received follow-up. The follow-up time ranged from 3 months to 144 months (median, 70 months). The 1-, 3- and 5-year survival rates were 94.7%, 86.8%, and 57.9% respectively. The median survival time was 62 months. The survival time of the patients with carcinoma infiltration exceeding bowel muscularis propria was (36+/-5) months, significantly shorter than that of patients without carcinoma infiltration exceeding the bowel muscularis propria [(73+/-5) months, P<0.05]. The survival time of the patients with positive lymph node metastasis was (34+/-7) months, significantly shorter than that of patients with negative lymph node metastasis [(74+/-5) months, P<0.05].

CONCLUSIONSClinical symptoms, signs of neuroendocrine carcinoma in the digestive system are nonspecific. The correct diagnosis should depend on histopathologic examination. Systematic treatments including radical resection of NEC are the preferable treatment.
