Tuberculosis of the stomach is quite rare, both as a primary or secondary infection. It can present as a facet of a multiorgan disease process or may result from immunodeficiency. Here, we report a rare, interesting case of gastric tuberculosis which morphologically mimicked advanced gastric cancer in a young, immunocompetent patient presenting with hematemesis and melena. The disease was diagnosed by biopsy, and responded well to antituberculosis medication without surgery. Clinicians must bear in mind that, even in the absence of immunodeficiency, as in this case, tuberculosis can involve any site in the gastrointestinal tract and may present with a variety of characteristics. Gastric tuberculosis should always be part of the differential diagnosis of chronic infiltrative lesions in the stomach.

Tuberculosis of the stomach is extremely rare. We report the case of a 38-year-old woman who presented with epigastric discomfort and a palpable mass that persisted for a period of one month. We also report our findings from the abdominal computed tomographic, upper endoscopic and endoscopic ultrasonographic examinations of the patient. Abdominal computed tomography (CT) showed the presence of a large mass with an irregularly contoured low attenuation lesion. Upper endoscopy and endoscopic ultrasonography revealed a protruding ulcerative mass with an ill-defined heteroechoic subepithelial lesion originating from the gastric submucosal layer. This was previously misdiagnosed as a gastrointestinal stromal tumour. Endoscopic biopsy specimen was positive on acid-fast bacillus staining, and polymerase chain reaction for Mycobacterium tuberculosis was also positive. Abdominal CT and endoscopy at the patient's three-month follow-up showed near complete resolution of the lesion.

OBJECTIVETo explore the risk factors and prognosis of No.8p lymph node metastasis in cases with advanced gastric cancer.

METHODSClinicopathological and follow-up data of 790 cases with advanced gastric cancer undergoing gastrectomy (including No.8p lymphadenectomy) from October 2003 to October 2013 in Fujian Provincial Tumor Hospital were analyzed retrospectively. Patients receiving neoadjuvant chemotherapy were excluded. Associations of No.8p lymph node metastasis with clinicopathological characteristics and metastasis in other regional lymph node were analyzed. Prognostic difference between positive No.8p group and negative No.8p group was examined.

RESULTSPositive No.8p lymph node was found in 93 cases (11.8%) among 790 cases with advanced gastric cancer. Univariate analysis showed that gender [male 9.8%(56/572) vs. female 17.0%(37/218), P=0.005], preoperative CEA level [<5 μg/L 28.0%(61/218) vs. ≥5 μg/L 5.6%(32/572), P=0.005], tumor size[diameter <5 cm 3.8%(13/346) vs. ≥5 cm 18.0%(80/445), P=0.000], tumor location [gastric fundus and cardiac 10.7% (26/244) vs. gastric body 13.5% (30/222) vs. gastric antrum 10.1% (31/308) vs. total gastric 37.5%(6/16), P=0.007], Borrmann staging [type II( 1.9%(4/211) vs. type III( 11.6% (54/464) vs. type IIII( 30.4%(35/115), P=0.000], tumor differentiation [high 0/8 vs. moderate 6.7%(25/372) vs. low 16.6%(68/410), P=0.000], T staging [T2 2.4%(4/170) vs. T3 13.1%(35/267) vs. T4 15.3%(54/353), P=0.000], N staging [N0 0 (0/227) vs. N1 2.2%(5/223) vs. N2 15.2%(26/171) vs. N3 36.7%(62/169), P=0.000] were closely associated with the No.8p lymph node metastasis. Multivariate analysis that revealed gender (OR=1.762, 95%CI: 1.020-3.043), tumor size (OR=1.107, 95%CI: 1.020-1.203), N staging (OR=4.093, 95%CI: 2.929-5.718), tumor differentiation (OR=1.782, 95%CI:1.042-3.049), and metastasis in No.8a(OR=5.370, 95%CI: 3.425-8.419), No.3(OR=1.127, 95%CI:1.053-1.206), No.6(OR=1.221,95%CI: 1.028-1.450), No.7(OR=2.149, 95%CI: 1.711-2.699), No,11p(OR=2.085, 95%CI: 1.453-2.994), No.14v(OR=2.604, 95%CI: 1.038-6.532) group lymph nodes were the independent risk factors of No.8p lymph node metastasis. One-year, 3-year and 5-year survival rates in positive No.8p group were 85.7%, 47.5% and 22.6%, and those in negative No.8p group were 96.2%, 82.5% and 70.3% respectively, whose differences were significant (χ=109.767, P<0.05).

CONCLUSIONSMetastasis in Np.8p lymph nodes is an important factor affecting the prognosis of patients with advanced gastric cancer. In patients with female gender, tumor diameter ≥5 cm, preoperative late N staging, low tumor differentiation or metastasis in No.8a, No.3, No.6, No.7, No.11p, No.14v group lymph nodes, thorough clean rance of No.8p group lymph node should be considered.

OBJECTIVETo investigate the prognostic factors of patients with lymph node-negative metastasis gastric cancer (pN0).

METHODSClinicopathological data of patients with pN0 gastric cancer who underwent radical operation at the Department of Surgical Oncology, The First Hospital of China Medical University from May 1980 to August 2012 were collected and analyzed retrospectively.

INCLUSION CRITERIA(1) Patients were diagnosed as gastric adenocarcinoma; (2) Postoperative pathology confirmed T1a to 4bN0M0 gastric cancer; (3) Total number of harvested lymph node was more than 15. The patients, who died within 1 month after the operation, died of other diseases, had remnant gastric cancer, or had incomplete follow-up data, were excluded. Univariate analysis was used to analyze the clinical factors that may influence the prognosis of patients with stage pN0 gastric cancer, then, those significant variables were entered into the Cox's proportional hazards regression model for multivariate analysis to obtain the independent prognostic factors for patients with pN0 gastric cancer finally. Furthermore, the prognosis of patients with pN0 advanced gastric cancer (invasive depth ≥ T2) were analyzed using the same method.

RESULTSA total of 610 patients with pN0 gastric cancer were enrolled in the study, including 441 males and 169 females with age ranging from 19 to 83 (mean 56.4±11.0) years, D1 lymph node dissection in 45 cases, D2 lymph node dissection in 543 cases, D3 lymph node dissection in 22 cases, and 384 cases of advanced gastric cancer. The overall followed-up was 1 to 372 (median 32) months. Ninety cases (14.8%) were dead during the follow-up. The median survival was 277.7(95%CI: 257.6 to 297.8) months, and the 1-, 3-, 5-year survival rates were 96.5%, 87%, 83.2%. Univariate analysis showed that tumor diameter, depth of invasion, gross type, lymph node dissection and lymph vessel cancer embolus were related to the prognosis (all P<0.05). The 5-year survival rate of patients with tumor diameter >4 cm was significantly lower than those with tumor diameter ≤4 cm (75.6% vs. 87.8%, P=0.000). The 5-year survival rates of T1a, T1b, T2, T3 and T4 were 98.4%, 92.8%, 84.2%, 61.0% and 31.4% respectively, and the difference was statistically significant (P=0.000). In gross type, 5-year survival rate of early gastric cancer was 96.0%, and of Borrmann I( to IIII( type gastric cancer was 100%, 83.4%, 73.7% and 68.9% respectively, whose difference was statistically significant(P=0.000). The 5-year survival rates in patients undergoing lymph node dissection D1, D2 and D3 were 100%, 83.3% and 58.7%, and the difference was significant (P=0.005). The 5-year survival rate of patients with positive lymphatic cancer embolus was lower than those with negative ones (69.4% vs. 86.9%, P=0.000). Multivariate analysis showed that the gross type [Borrmann II(/early gastric cancer: HR(95% CI)=15.129(3.284 to 69.699), Borrmann III(/early gastric cancer: HR(95% CI)=14.613 (3.292 to 64.875), Borrmann IIII(/early gastric cancer: HR (95% CI)=15.430 (2.778 to 85.718),Borrmann IIIII(/early gastric cancer: HR(95%CI)=12.604 (1.055 to 150.642), P=0.025] and the positive lymphatic cancer embolus [HR(95% CI)=3.241 (2.056 to 5.108), P=0.000] were the independent prognostic factors of patients with pN0 gastric cancer. For pN0 patients with advanced gastric cancer, multivariate analysis showed that the depth of invasion [stage T3/stage T2: HR(95%CI)=1.520 (0.888 to 2.601), stage T4/stage T2: HR(95%CI)=2.235(1.227 to 4.070); P=0.031] and the positive lymphatic cancer embolus [HR(95%CI)=3.065 (1.930 to 4.868); P=0.000] were the independent risk factors influencing the prognosis.

CONCLUSIONSPositive lymphatic cancer embolus and worse gross pattern indicate poorer prognosis of patients with pN0 gastric cancer, which may be used as effective markers in evaluating the prognosis. As for pN0 advanced gastric cancer, invasion depth and positive lymphatic cancer embolus can play a more important role in the prediction.

Gastric cancer (GC) is one of the most common tumor in the world, and remains a major public health problem and one of the leading causes of death. Recently many researches have demonstrated that systemic inflammatory response is associated with prognosis and response to therapy in gastric cancer, and the peripheral blood count test can partly reflect the systemic inflammatory response. Based on the peripheral blood count test, there are a lot of research regarding the relation between the platelet count (PLT), neutrophil, lymphocyte, white blood cell (WBC), neutrophil to lymphocyte ratio(NLR), platelet to lymphocyte ratio (PLR) with their prognostic role in gastric cancer. A high PLT and preoperative lymphocytopenia are both associated with increased lymph node metastasis, stage (III(+IIII(), serosal invasion (T3+T4) risk and poorer overall survival. Besides above, platelet monitoring following surgery can be applied to predict the recurrence for patients with GC that suffer preoperative high PLT but have restored PLT levels following resection. Moreover systemic inflammatory factors based on blood parameters, such as PLR, NLR and so on, have relation with the poor prognosis of patients with GC. Among them, high NLR is a negative predictor of prognosis in GC patients. However PLR remains inconsistent, while most researches demonstrated high PLR may be useful prognostic factor rather than independent prognostic factor. There are still some limitations which include various cut-off values, little of clinician attention, the uncertain mechanism, etc. Here we review the research progress in the prognostic role of the blood count test in gastric cancer.

BACKGROUND/AIMS: The well-organized study to support that increased cholelithiasis and bile duct dilatation can occur after gastrectomy has not been reported. The aim of this study was to determine the incidence of cholelithiasis and the degree of common bile duct (CBD) dilatation in patients undergoing subtotal gastrectomy, compared to those undergoing endoscopic treatment for gastric cancer. METHODS: Patients who diagnosed with gastric cancer and received treatment at six academic referral centers were investigated for the incidence and time of cholelithiasis and the degree of CBD dilatation after treatment by analysis of 5-year follow-up CTs. The operation group underwent subtotal gastrectomy without vagotomy, while in the control group endoscopic treatment was administered for gastric cancer. RESULTS: A total of 802 patients were enrolled in 5-year analysis (735 patients in the operation group and 67 patients in the control group). Cholelithiasis occurred in 47 patients (6.39%) in the operation group and 3 patients (4.48%) in the control group (p=0.7909). The incidences of cholelithiasis were 4.28% in Billoth-I and 7.89% in Billoth-II (p=0.0487). The diameter of proximal CBD and distal CBD increased by 1.11 mm and 1.41 mm, respectively, in the operation group, compared to 0.4 mm and 0.38 mm, respectively, in the control group (p<0.05). Patients with increased CBD dilatation more than 5 mm showed statistically significant increases in alkaline phosphatase and gamma-glutamyltransferase. CONCLUSIONS: The incidence of cholelithiasis was not increased due to subtotal gastrectomy without vagotomy, but the incidence was higher after Billoth-II compared to Billoth-I. In addition, significant change in the CBD diameter was observed after subtotal gastrectomy.

OBJECTIVETo evaluate the clinical significance of No.12 lymph node dissection for advanced gastric cancer with D2 lymphadenectomy.

METHODSClinicopathologic data and No.12 lymph node dissection of 256 advanced gastric cancer patients undergoing radical operation in our department between January 2005 and December 2010 were retrospectively summarized and the influence factors of metastasis in No.12 lymph nodes were analyzed.

RESULTSOf 256 patients, 179 were male and 77 were female with the average age of 59.2 years. Tumor located in the upper of stomach in 24 cases, middle of stomach in 41 cases, lower of stomach in 174 cases, multi-focus or diffuse distribution of stomach in 17 cases. Tumor diameter was <3 cm in 39 cases, 3 to 5 cm in 100 cases, >5 cm in 117 cases. Serum carcinoembryonic antigen (CEA) level increased in 61 cases, serum carbohydrate antigens (CA)72-4 increased in 56 cases and CA19-9 increased in 61 cases. The number of No.12 lymph nodes resected from all the patients was 1 152, and the average number was 4.5±1.9. The metastasis rate of No.12 lymph nodes was 9.4%(24/256) after hematoxylin eosin staining (positive group). All the patients received effective follow-up to December 2015, and the average follow-up time was 101.2 months. The median survival time of positive No.12 group (24 cases) was 29.8 months and of negative No.12 group (232 cases) was 78.2 months, whose difference was statistically significant (χ=21.715, P=0.000). Univariate analysis found that No.12 lymph node metastasis was not associated with age, gender, tumor differentiation (all P>0.05), but was associated with tumor location, tumor diameter, invasive depth (all P<0.05), and was closely associated with Borrmann type, outside metastatic lymph nodes of No.12 and high levels of serum CEA, CA72-4 and CA19-9 (all P=0.000). Multivariate regression analysis found that tumor location (RR=2.452, 95%CI:1.537 to 3.267, P=0.000), Borrmann type (RR=1.864, 95%CI:1.121 to 3.099, P=0.016) and number of outside metastatic lymph nodes of No.12 (RR=2.979, 95%CI: 2.463 to 3.603, P=0.000) were the independent risk factors of the No.12 metastasis (P<0.05).

CONCLUSIONSMetastasis in No.12 lymph nodes indicates poorer prognosis. The No.12 lymph nodes of advanced gastric cancer patients with curative resection, especially those with the tumor located in the lower part, Borrmann type IIII(, outside metastatic lymph nodes of No.12, should be regularly cleaned.

Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents. Anastomotic fistula is a serious postoperative complication. In addition to endoscopically placing the small intestine nutrition tube for early enteral nutrition support treatment, endoscopic treatment, including stent, metal clip, OTSC, and Over-stitch suture system, can be chosen to close fistula. For anastomotic obstruction or stricture, endoscopic balloon or probe expansion and stent placement can be chosen. For esophageal anastomotic intractable obstruction after gastroesophageal surgery, radial incision of obstruction by the hook knife or IT knife, a new method named ERI, is a good choice. Bile leakage caused by bile duct injury can be treated by placing the stent or nasal bile duct. In addition, endoscopic methods are widely used as follows: abdominal abscess can be treated by the direct intervention under endoscopy; adhesive ileus can be treated by placing the catheter under the guidance of endoscopy to attract pressure; alkaline reflux gastritis can be rapidly diagnosed by endoscopy; gastric outlet obstruction mainly caused by cancer recurrence can be relieved by metal stent placement and the combination of endoscopy and X-ray can increase success rate; pyloric dysfunction and spasm caused by the vagus nerve injury during proximal gastrectomy can be treated by endoscopic pyloromyotomy, a new method named G-POEM, and the short-term outcomes are significant. Endoscopic submucosal dissection (ESD) allows complete resection of residual gastric precancerous lesions, however it should be performed by the experienced endoscopists.
