    A total of 58 cases with inoperable advanced gastric carcinomas were treated by radiotherapy combined with tegafur, and the result was analyzed mainly from the aspects of life expectancies and some prognostic factors. Median survival time of all cases was 8.9 months. Actuarial survival rates at one, two, three, four and five years were 45%, 22%, 14%, 14% and 11% respectively. Cancer type, histologic type, tumor size and radiation effect on the primary lesion were chosen as the prognostic factors, and examined using median survival time as a parameter. Borrmann IV type cancer showed an unequivocally poor prognosis, whereas no significant prognostic differences were seen among other types. Poorly differentiated adenocarcinoma gave a poor prognosis. Radiation effect on the primary lesion seemed to have a positive correlation with prognosis, while life expectancies became shorter with the increase of tumor size. It seems, from the present study, that this combination therapy contributes a great deal to life prolongation of patients with inoperable advanced gastric carcinomas.

Methods and Materials. Between November 1993 and March 2010, 137 patients with LAIGC receiving CF (2 Gy daily or AHF (1.3 Gy b.i.d. to total at least 50 Gy RT in combination or without chemotherapy were retrospectively selected from the hospital database of Arkhangelsk clinical oncological dispensary. Overall survival (OS assessed using actuarial analysis, Kaplan – Meier method and Cox regression. results. The CF and AHF groups were 102 and 35 patients, respectively. Median follow-up time for all patients was 12 years. By the time of analysis 123 (90 % patients of all cohort died. Median, 7-year survival were 24 (95 % confidence intervals (CI, 17–31 vs 16 (95 % CI, 11–21 months, hazard ratio (HR=0.71 (95 % CI, 0.46–1.06, р=0.097; and 19 % (95 % CI 8–34 % vs 6% (95 % CI 2–13 % in the AHF and CF groups, respectively. In multivariate OS model the difference decreased to HR=0.87 (95 % CI, 0.49–1.55. The location of the tumor in median third (HR=0.60, 95 % CI, 0.37–0.99 in refer to upper third was the only independent factor influencing survival.  There was no influence of the total dose in chosen level on survival. conclusion. Our retrospective shows trend towards better OS for those LAIGC patients receiving RT in AHF regimen compared to CF. The prospective randomized study with conformal radiation technics is necessary to confirm these findings.

    Purpose: The results of a pilot study using S-1/low-dose cisplatin/radiotherapy led us to hypothesize that the initial chemoradiotherapy regimen would induce a 70% efficacy rate with a 10% pathologic complete response rate. Patients and Methods: Only patients with unresectable or incurable advanced gastric cancer were eligible. The patients received induction S-1 and cisplatin therapy with radiotherapy followed by chemotherapy alone. Results: Of the 30 patients recruited and assessed, 29 were eligible for clinical evaluation of measurable lesions. The response rate was 65.5%, with 19 with a partial response, 8 with no change, and 2 with progressive disease of 29 patients. Of the 30 patients recruited, 10 (33.3%) underwent stomach resection and D2 LN dissections. The pathologic complete response rate was 13.3% (4 patients), and the R0 resection rate was 100% (10 patients). The survival analysis showed a median survival time of 25 months. Grade 3 toxicity occurred in 66.7% for leukocytopenia, 33.3% for thrombocytopenia, 23.3% for nausea and appetite loss, and 6.7% for anemia, diarrhea, and renal dysfunction. Although all the patients had been hospitalized with a poor performance status with a giant tumor, 97% (29 of 30) could be discharged after the first cycle, resulting in an improvement in quality of life. Conclusion: Chemoradiotherapy could be a powerful regimen for controlling tumor progression in advanced gastric cancer, improving patients' quality of life with tolerable toxicity. A complete histologic response rate of >10% would be expected, even for large tumors with metastatic lesions

    Proton beam radiation therapy using 250 MeV protons was carried out on two patients with early gastric cancer (T1, N0, M0). One patient was an 85-year-old man with early gastric cancer of type IIa + IIc. The other one was a 70-year-old man with early gastric cancer of type IIc. In both cases histological examination of biopsy specimens showed differential adenocarcinoma; distant metastasis was not found by other examinations. Both patients were considered inoperable due to their poor cardiac and/or respiratory functions. Therefore, it was decided to treat them by definitive proton irradiation, delivering total doses of 86 Gy and 83 Gy, respectively. In both patients, skin erythema that did not require any special treatment was found in the irradiation field. Hematobiological examinations did not show any abnormality. Although endoscopic examination at two years after irradiation in the former case and at seven months in the latter case showed persistent gastric ulcer at the site of the cancerous lesions, cancer cells were not found histologically. Therefore, we concluded that proton irradiation therapy was useful for inoperable early gastric cancers. (author)

  5. Endoscopic Management of Tumor Bleeding from Inoperable Gastric Cancer

    Tumor bleeding is not a rare complication in patients with inoperable gastric cancer. Endoscopy has important roles in the diagnosis and primary treatment of tumor bleeding, similar to its roles in other non-variceal upper gastrointestinal bleeding cases. Although limited studies have been performed, endoscopic therapy has been highly successful in achieving initial hemostasis. One or a combination of endoscopic therapy modalities, such as injection therapy, mechanical therapy, or ablative therapy, can be used for hemostasis in patients with endoscopic stigmata of recent hemorrhage. However, rebleeding after successful hemostasis with endoscopic therapy frequently occurs. Endoscopic therapy may be a treatment option for successfully controlling this rebleeding. Transarterial embolization or palliative surgery should be considered when endoscopic therapy fails. For primary and secondary prevention of tumor bleeding, proton pump inhibitors can be prescribed, although their effectiveness to prevent bleeding remains to be investigated. PMID:25844339

    Malnutrition is common in patients with gastric cancer. Early identification of malnourished patients results in improving quality of life. We aimed to assess the nutritional status of patients with inoperable gastric adenocarcinoma (IGA) and finding a precise malnutrition screening score for these patients before the onset of chemotherapy. Nutritional status was assessed using patient generated subjective global assessment (PG-SGA), visceral proteins, and high-sensitivity C reactive protein. Tumor markers of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA-125) and CA 19-9 and their association with nutritional status were assessed. Then a new score for malnutrition screening was defined. Seventy-one patients with IGA completed the study. Malnourished and well-nourished patients (based on PG-SGA) were statistically different regarding albumin, prealbumin and CA-125. The best cut-off value for prealbumin for prediction of malnutrition was determined at 0.20 mg/dl and using known cut-off values for albumin (3.5 g/dl) and CA-125 (35 U/ml), a new score was defined for malnutrition screening named MS-score. According to MS-score, 92% of the patients had malnutrition and it could predict malnutrition with 96.8% sensitivity, 50% specificity and accuracy of 91.4%. MS-score has been suggested as an available and easy-to-use tool for malnutrition screening in patients with IGA. © The Author 2017. Published by Oxford University Press. All rights reserved.

    Full Text Available Adenoid cystic carcinoma is rare and usually arises in the salivary glands. It grows slowly, but is characterized by easy perineural invasion with local infiltration and distant metastasis. In metastatic setting, the efficacy of intravenous chemotherapy is limited. Herein, we report one male patient who had a advanced, inoperable adenoid cystic carcinoma with lung metastasis, presenting with right buccal unhealed ulcer, pain and poor intake, whose loco-regional tumors responded dramatically after intra-arterial chemotherapy and his symptoms were almost completely relieved. We also make a literature review for treatment of adenoid cystic carcinoma.

    Background and purpose: High dose rate intraluminal brachytherapy for tumours of the rectal and anal canal which were inoperable either because of the age and frailty of the patient or because of advanced disease has been evaluated. Patients and methods: In a retrospective review of 50 consecutive patients the two main indications for brachytherapy were as part of a radical radiation programme in those unfit for major surgery (26 patients) or as palliation for advanced or metastatic disease (22 patients). Radical treatment was either sole treatment delivering 6 Gy fraction 2 to 3 times weekly up to 36 Gy or as a boost of 12 Gy after 45 Gy in 25 fractions external beam chemoradiation. Palliative treatments were given predominantly as a single dose of 10 Gy. Results: This was predominantly a group of frail elderly patients with a median age of 82 years (range 35-91). Local tumour response was seen in 21/25 assessable patients with 14 complete responses. Median survival for the entire population was 6 months (range 1-54 months); in patients treated with 'radical' intent this was 25 months (range 1.5-54) and in the palliative group 7.2 months (range 1-37). The most common presenting symptom was bleeding per rectum for which a 64% response rate was obtained with 57% complete responses. Mucous discharge responded in 64% with 28% complete responses. The median duration of response was 7 months. Conclusion: Intraluminal HDR brachytherapy is an effective local treatment for patients otherwise unfit for radical surgery both as a component of radical treatment, or as a simple single palliative procedure

    Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. To assess the efficacy of chemotherapy versus best supportive care (BSC), combination versus single-agent chemotherapy and different chemotherapy combinations in advanced gastric cancer. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and Embase up to June 2016, reference lists of studies, and contacted pharmaceutical companies and experts to identify randomised controlled trials (RCTs). We considered only RCTs on systemic, intravenous or oral chemotherapy versus BSC, combination versus single-agent chemotherapy and different chemotherapy regimens in advanced gastric cancer. Two review authors independently identified studies and extracted data. A third investigator was consulted in case of disagreements. We contacted study authors to obtain missing information. We included 64 RCTs, of which 60 RCTs (11,698 participants) provided data for the meta-analysis of overall survival. We found chemotherapy extends overall survival (OS) by approximately 6.7 months more than BSC (hazard ratio (HR) 0.3, 95% confidence intervals (CI) 0.24 to 0.55, 184 participants, three studies, moderate-quality evidence). Combination chemotherapy extends OS slightly (by an additional month) versus single-agent chemotherapy (HR 0.84, 95% CI 0.79 to 0.89, 4447 participants, 23 studies, moderate-quality evidence), which is

    Full Text Available Background. There is a considerable dissimilarity in the survival duration of the patients with gastric cancer. We aimed to assess the systemic inflammatory response (SIR and nutritional status of these patients before the commencement of chemotherapy to find the appropriate prognostic factors and define a new score for predicting metastasis. Methods. SIR was assessed using Glasgow Prognostic Score (GPS. Then a score was defined as prealbumin/CRP based prognostic score (PCPS to be compared with GPS for predicting metastasis and nutritional status. Results. 71 patients with gastric cancer were recruited in the study. 87% of patients had malnutrition. There was a statistical difference between those with metastatic (n=43 and those with nonmetastatic (n=28 gastric cancer according to levels of prealbumin and CRP; however they were not different regarding patient generated subjective global assessment (PG-SGA and GPS. The best cut-off value for prealbumin was determined at 0.20 mg/dL and PCPS could predict metastasis with 76.5% sensitivity, 63.6% specificity, and 71.4% accuracy. Metastatic and nonmetastatic gastric cancer patients were different in terms of PCPS (P=0.005. Conclusion. PCPS has been suggested for predicting metastasis in patients with gastric cancer. Future studies with larger sample size have been warranted.

    To examine toxicity and outcomes for patients treated with preoperative chemoradiotherapy (CRT) for gastric cancer. Patients with gastroesophageal (GE) junction (Siewert type II and III) or gastric adenocarcinoma who underwent neoadjuvant CRT followed by planned surgical resection at Duke University between 1987 and 2009 were reviewed. Overall survival (OS), local control (LC) and disease-free survival (DFS) were estimated using the Kaplan-Meier method. Toxicity was graded according to the Common Toxicity Criteria for Adverse Events version 4.0. Forty-eight patients were included. Most (73%) had proximal (GE junction, cardia and fundus) tumors. Median radiation therapy dose was 45 Gy. All patients received concurrent chemotherapy. Thirty-six patients (75%) underwent surgery. Pathologic complete response and R0 resection rates were 19% and 86%, respectively. Thirty-day surgical mortality was 6%. At 42 months median follow-up, 3-year actuarial OS was 40%. For patients undergoing surgery, 3-year OS, LC and DFS were 50%, 73% and 41%, respectively. Preoperative CRT for gastric cancer is well tolerated with acceptable rates of perioperative morbidity and mortality. In this patient cohort with primarily advanced disease, OS, LC and DFS rates in resected patients are comparable to similarly staged, adjuvantly treated patients in randomized trials. Further study comparing neoadjuvant CRT to standard treatment approaches for gastric cancer is indicated

    An unusual case of advanced synchronous colon and gastric carcinoma is described. A 36 year old female was admitted to our Department with a stenosing right colon cancer diagnosed at endoscopy which was performed for lower crampy abdominal pain and gross blood in the stool. Multiple colon polyps, distal to the tumor, were also detected. On preoperative abdominal computed tomography, a stenosing right colon cancer, without evidence of abdominal diffusion, was confirmed. At laparotomy, in addition to colon cancer, an antral gastric cancer was incidentally found. En bloc hemi gastrectomy and subtotal colectomy were performed. Digestive continuity was restored by gastrojejunal and ileosigmoid anastomoses. At histology, a poorly differentiated gastric adenocarcinoma with signet ring-cell component (pT2, pN0; stage IB) and a moderately differentiated colon adenocarcinoma with a tubulovillous component (pT3, pN1; stage III, Stage Dukes C) were revealed. Both tumors showed a low expression of p53 and c-erb2 oncoproteins. No genetic defect was identified in the APC and MMR genes. The patient is alive, without recurrence, two years after the operation

    One hundred twenty-nine patients with far advanced or recurrent gastric carcinoma underwent computed tomography (CT) of the abdomen. There were three histologic types: differentiated (n=41), undifferentiated (n=68), and unclassified (n=20). Eighteen patients who had developed obstructive jaundice were retrospectively studied to elucidate the nature of obstruction with histologic correlation. In differentiated carcinomas tumor tended to grow in an expansive fashion. A fairly large, well-defined lymph adenopathy was observed on CT. The extrahepatic bile duct surrounded by lymph nodes appeared as ''doughnot sign'' in six of eight patients. Undifferentiated gastric carcinoma had tendency to extend infiltratively. Bile duct obstruction was only a part of diffuse spreading. In spite of the presence of obstructive jaundice, no discrete mass was demonstrated around the extrahepatic bile duct on CT. In none of nine patients was present ''doughnot sign''. The significance of lymph node dissection along the extrahepatic bile duct in patients with differentiated gastric carcinoma was emphasized. The region of hepatoduodenal and pancreatico-duodenal lymph nodes should be carefully evaluated in interpretation of abdominal CT. (author)

    Objective: To evaluate the outcome of radiotherapy for locally advanced pancreatic cancer. Methods: From January 2000 to December 2007, 41 patients with inoperable locally advanced (stage III) pancreatic cancer were treated with three-dimensional conformal radiation therapy(3DCRT) or intensity-modulated radiation therapy (IMRT). Among these patients, 30 received concurrent radio-chemo-therapy. Results: The median survival time(MST) and 1-year overall survival were 9.2 months and 23%. Patients with pretreatment KPS ≥ 80, no regional lymph nodes metastasis, and CR/PR after radiotherapy had better prognosis. The corresponding MSTs were 11.1 months vs 5.8 months (χ 2 =7.50, P=0.006), 10.8 months vs 6.5 months(χ 2 =5.67, P=0.017), and 19.5 months vs 9.1 months (χ 2 =7.28, P=0.007), respectively. Concurrent radio-chemotherapy tended to improve the overall survival(χ 2 =3.25, P=0.072). After radiotherapy, 18 patients had clinical benefit response, mainly being abdominal pain relief. Neither grade 4 hematologic nor grade 3 non-hematologic toxicities were observed. Conclusions: For patients with locally advanced pancreatic cancer, both 3DCRT and IMRT are effective in alleviation of disease-related symptoms. Patients with better performance status before treatment, no regional lymph nodes metastasis, and better response to radiotherapy may have better prognosis. Concurrent radio-chemotherapy trend to improve overall survival when compared with radiotherapy alone. (authors)

    In this prospective, non-randomized study we compare the results of simultaneous radiochemotherapy (RCT) with those of concomitant boost treatment (CBT) in advanced head and neck cancer. From January 1993 to March 1999, 77 patients were treated with cisplatin, 5-FU, and 70.2 Gy (accelerated split-course); from January 1995 to March 1999, a further 33 patients received CBT to a total dose of 72 Gy. Toxicities were prospectively recorded according to RTOG/EORTC criteria. Acute and subacute reactions did not differ significantly. Severe late effects (III/IV) remained anecdotal (one fistula). Therapy-associated mortalities were 3%(RCT) vs. 0% (CBT), most tumors responding well to therapy (CR + PR: RCT: 72%, CBT: 63%). The 2-year probabilities for freedom from locoregional progression amounted to 42% (RCT) and 31% (CBT); p > 0.05. Tumor-specific 2-year survival amounted to 40% (RCT) and 34% (CBT); p > 0.05. Both of the treatment concepts yield high remission rates with moderate toxicities. Nevertheless, median time to recurrence is still fairly short. We could not find any differences for local control and survival. For patients who are not able to complete the full three courses of radiochemotherapy, the concomitant boost schedule presents a good alternative

    A phase II trial was conducted to evaluate the efficacy and toxicity of a modulation of 5-fluorouracil (5-FU) by methotrexate (MTX) (with leucovorin (LV) rescue) as first-line chemotherapy in patients with locally advanced (inoperable) or metastatic gastric carcinoma. From July 1993 through August 1996, 36 patients with advanced gastric carcinoma received a regimen that consisted of: MTX 200 mg/m2 diluted in 250 ml normal saline by intravenous infusion over 20 minutes at hour 0; 5-FU 1,200 mg/m2 intravenous push injection at hour 20. Beginning 24 hours after MTX administration all patients received LV 15 mg/m2 intramuscularly every 6 hours for six doses. Cycles were repeated every 15 days. One patient was not assessable for response. Objective regression was observed in 15 of 37 patients (43%; 95% confidence interval, 26%-60%). One patient (3%) achieved complete response and 14 (40%) achieved partial response. No change was recorded in 14 patients (40%) and progressive disease was noted in six patients (17%). The median time to treatment failure was 7 months and the median survival was 12 months. Toxicity was within acceptable limits but one therapy-related death resulting from severe leukopenia occurred. The dose-limiting toxicity was mucositis. Five episodes of grade 3 or 4 stomatitis were observed and caused dosage modifications of MTX and 5-FU. Biochemical modulation of 5-FU by MTX appears as an attractive modality in patients with advanced gastric cancer. Further investigation both in experimental and clinical fields is needed to clearly define its role and to design the best modulatory strategy.

  2. Recent advances in gastric emptying scintigraphy

    Gastric emptying scintigraphy was introduced more than 25 years ago by Grittith and still remains the gold standard to assess gastric emptying. Test meals, radiopharmaceuticals and acquisition procedures have been refined and optimized over the years and the test procedure is now pretty well standardized. However, in its most common use, gastric emptying scintigraphy provides little information on gastric physiology. Over the last decade, modelling of the liquid and solid emptying curves have brought some insight in the complex gastric physiology. Compartmental analysis of the stomach has also provided information on the pathophysiological mechanisms of delayed gastric emptying. Over the past 5 years, the most dramatic development in gastric emptying scintigraphy has been the introduction of Digital Antral Scintigraphy (DAS). Digital Antral scintigraphy basically consists in dynamically imaging of the stomach and the use of a refined Fourier transform processing method. This new procedure allows for the visualization of antral contractions and, alike manometry, permits quantitative characterization on the frequency and amplitude of these contractions. Overall, this new procedure provides a unique, non invasive tool to characterize gastric motility, to define the pathophysiologic mechanisms of gastric motor disorders and to evaluate the effect of new gastro-kinetic compounds.

    Although medical treatment has been shown to improve quality of life and prolong survival, no significant progress has been made in the treatment of advanced gastric cancer (AGC) within the last two decades. Thus, the optimum standard first-line chemotherapy regimen for AGC remains debatable, and most responses to chemotherapy are partial and of short duration; the median survival is approximately 7 to 11 months, and survival at 2 years is exceptionally > 10%. Recently, remarkable progress in tumor biology has led to the development of new agents that target critical aspects of oncogenic pathways. For AGC, many molecular targeting agents have been evaluated in international randomized studies, and trastuzumab, an anti-HER-2 monoclonal antibody, has shown antitumor activity against HER-2-positive AGC. However, this benefit is limited to only ~20% of patients with AGC (patients with HER-2-positive AGC). Therefore, there remains a critical need for both the development of more effective agents and the identification of molecular predictive and prognostic markers to select those patients who will benefit most from specific chemotherapeutic regimens and targeted therapies.

    We studied the effects of a splenectomy in combination with immunotherapy on the survival of patients who had undergone a total gastrectomy. It was found that a splenectomy was not effective against advanced gastric cancer at stage III, and that the spleen should be retained for immunotherapy. Splenectomy for gastric cancer at terminal stage IV, particularly in combination with immunotherapy, produced not only augmentation of cellular immunity, but also increased survival.

Prognosis remains poor with most patients presenting with advanced or metastatic disease. A better understanding of angiogenesis has led to the investigation of drugs that inhibit the vascular endothelial growth factor (VEGF pathway including anti-VEGF antibody therapy (eg, bevacizumab, inhibitors of angiogenic receptor tyrosine kinases (eg, sunitinib, sorafenib, apatinib, regorafenib, and inhibitors of vascular endothelial growth factor receptors (VEGFRs (eg, ramucirumab. Ramucirumab, a VEGFR-2 inhibitor, is the first anti-angiogenic agent approved by the US Food and Drug Administration for use in the treatment of advanced gastric cancers. This review will focus on the clinical utility and potential use of ramucirumab in advanced gastric cancer.

    To evaluate treatment outcome of patients with high risk locally advanced gastric cancer after postoperative chemoradiotherapy. Between May 2003 and May 2012, thirteen patients who underwent postoperative chemoradiotherapy for gastric cancer with resection margin involvement or adjacent structure invasion were retrospectively analyzed. Concurrent chemotherapy was administered in 10 patients. Median dose of radiation was 50.4 Gy (range, 45 to 55.8 Gy). The median follow-up duration for surviving patients was 48 months (range, 5 to 108 months). The 5-year overall survival rate was 42% and the 5-year disease-free survival rate was 28%. Major pattern of failure was peritoneal seeding with 46%. Loco-regional recurrence was reported in only one patient. Grade 2 or higher gastrointestinal toxicity occurred in 54% of the patients. However, there was only one patient with higher than grade 3 toxicity. Despite reported suggested role of adjuvant radiotherapy with combination chemotherapy in gastric cancer, only very small portion of the patients underwent the treatment. Results from this study show that postoperative chemoradiotherapy provided excellent locoregional control with acceptable and manageable treatment related toxicity in patients with high risk locally advanced gastric cancer. Thus, postoperative chemoradiotherapy may improve treatment result in terms of locoregional control in these high risk patients. However, as these findings are based on small series, validation with larger cohort is suggested.

    Radical gastrectomy is main treatment of gastric cancer. We analyzed patients with stage III and IV stomach cancer who had radical operation and received postoperative radiation therapy combined with or without chemotherapy retrospectively. From March 1985 to June 1993, 68 patients treated with curative resection and received postoperative adjuvant radiotherapy with 36Gy or more were evaluated. Median age was 60years(range 28-66 yrs). Thirty seven patients had non signet ring adenocarcinoma, 29 signet ring cell, 2 other cell. Patients with stage IIIA, IIIB, IV disease were 19, 25 and 24 respectively. Chemotherapy was given to all patients except two. Five-year overall survival and disease-free survival rate were 36.6% and 33.6T, respectively. Recurrence was documented in 34 patients. High recurrence was seen in omentum and peritoneum with 23.5%, and remnant stomach, anastomosis site, A-loop and E-loop had also high recurrence with 13.2%. In field locoregional recurrence was 20.7% and total distant metastases were 39.7%. Total intraabdominal failure was 47.1% and extraabdominal failure was 13.2%. Treatment toxicity was considered to be acceptable. 22.1% of patients had grade 3 and only 1 patient had grade 4 leukopenia. Six patients(8.8%) had weigh loss more than 10%. Treatment toxicity was acceptable with combined treatment with chemotherapy and radiotherapy. Locoregional recurrence was relatively low compared to distant failure with addition of irradiation. Peritoneal and omental seeding was high. Five-year survival was increased with combined modality. Radiation may eradicate minimal residual disease and improve survival. Furthermore to reduce intraabdominal failure, role of intraabdominal chemotherapy in addition to combined chemotherapy plus radiation has to be explored. (author).

    Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

    Full Text Available Gastric carcinoma is one of the major causes of cancer-related mortality worldwide. Early detection and treatment leads to an excellent prognosis in patients with early gastric cancer (EGC, whereas the prognosis of patients with advanced gastric cancer (AGC remains poor. It is unclear whether EGCs and AGCs are distinct entities or whether EGCs are the beginning stages of AGCs. We performed whole exome sequencing of four samples from patients with EGC and compared the results with those from AGCs. In both EGCs and AGCs, a total of 268 genes were commonly mutated and independent mutations were additionally found in EGCs (516 genes and AGCs (3104 genes. A higher frequency of C>G transitions was observed in intestinal-type compared to diffuse-type carcinomas (P = 0.010. The DYRK3, GPR116, MCM10, PCDH17, PCDHB1, RDH5 and UNC5C genes are recurrently mutated in EGCs and may be involved in early carcinogenesis.

    Full Text Available BACKGROUD: There is substantial evidence that infection with Helicobacter pylori plays a role in the development of gastric cancer and that it is rarely found in gastric biopsy of atrophic gastritis and gastric cancer. On advanced gastric tumors, the bacteria can be lost from the stomach. AIMS: To analyze the hypothesis that the prevalence of H.pylori in operated advanced gastric carcinomas and adjacent non-tumor tissues is high, comparing intestinal and diffuse tumors according to Lauren's classification METHODS: A prospective controlled study enrolled 56 patients from "Hospital Universitário", Federal University of Rio Grande do Norte, Natal, RN, Brazil, with advanced gastric cancer, treated from February 2000 to March 2003. Immediately after partial gastrectomy, the resected stomach was opened and several mucosal biopsy samples were taken from the gastric tumor and from the adjacent mucosa within 4 cm distance from the tumor margin. Tissue sections were stained with hematoxylin and eosin. Lauren's classification for gastric cancer was used, to analyse the prevalence of H. pylori in intestinal or diffuse carcinomas assessed by the urease rapid test, IgG by ELISA and Giemsa staining. H. pylori infected patients were treated with omeprazole, clarithromycin and amoxicillin for 7 days. Follow-up endoscopy and serology were performed 6 months after treatment to determine successful eradication of H. pylori in non-tumor tissue. Thereafter, follow-up endoscopies were scheduled annually. Chi-square and MacNemar tests with 0.05 significance were used. RESULTS: Thirty-four tumors (60.7% were intestinal-type and 22 (39.3% diffuse type carcinomas. In adjacent non-tumor gastric mucosa, chronic gastritis were found in 53 cases (94.6% and atrophic mucosa in 36 patients (64.3%. All the patients with atrophic mucosa were H. pylori positive. When examined by Giemsa and urease test, H. pylori positive rate in tumor tissue of intestinal type carcinomas was

    Background. Local progression of advanced gastric cancer often manifests as bleeding, dysphagia/obstruction, or pain. We evaluated the magnitude and durability of palliation with radiotherapy (RT). Material and methods. From 1996 to 2004, 37 gastric cancer patients were treated with palliative RT (median dose 35Gy in 14 fractions). Nearly two-thirds of all patients received concurrent chemoradiation therapy (CRT). Index pre-treatment symptoms were gastric bleeding, dysphagia/obstruction, and pain in 54%, 43%, and 19% of patients, respectively. Results. The rates of control for bleeding, dysphagia/obstruction, and pain were 70% (14/20), 81% (13/16), and 86% (6/7), respectively. These symptoms were controlled without additional interventions for a median of 70%, 81%, and 49% of the patient's remaining life, respectively. Patients receiving CRT had a trend towards better median overall survival than those receiving RT alone (6.7 vs. 2.4 months, p=0.08). Lower (<41 Gy) biologically effective dose (BED, assuming an alpha/beta ratio of 10 for early responding tissues) predicted for poorer local control (6-month local control 70% vs. 100%, p=0.05) while T4 tumors had a trend towards inferior local control (6-month LC 56% vs. 100%, p=0.06). Discussion. Palliative RT controls symptoms for most of the remaining life in the majority of gastric cancer patients. The role of a higher dose of RT (BED >= 41 Gy), especially in patients with T4 tumors, remains to be established. In order to accurately define the role for radiotherapy in palliation of these symptoms, prospective randomized studies need to be conducted.

    2011-01-01

    Purpose: Recent clinical trials and meta-analyses have shown that both CHART (continuous hyperfractionated accelerated radiation therapy) and induction chemotherapy offer a survival advantage over conventional radical radiotherapy for patients with inoperable non-small cell-lung cancer (NSCLC). This multicenter randomized controlled trial (INCH) was set up to assess the value of giving induction chemotherapy before CHART. Methods and Materials: Patients with histologically confirmed, inoperable, Stage I-III NSCLC were randomized to induction chemotherapy (ICT) (three cycles of cisplatin-based chemotherapy followed by CHART) or CHART alone. Results: Forty-six patients were randomized (23 in each treatment arm) from 9 UK centers. As a result of poor accrual, the trial was closed in December 2007. Twenty-eight patients were male, 28 had squamous cell histology, 34 were Stage IIIA or IIIB, and all baseline characteristics were well balanced between the two treatment arms. Seventeen (74%) of the 23 ICT patients completed the three cycles of chemotherapy. All 42 (22 CHART + 20 ICT) patients who received CHART completed the prescribed treatment. Median survival was 17 months in the CHART arm and 25 months in the ICT arm (hazard ratio of 0.60 [95% CI 0.31-1.16], p = 0.127). Grade 3 or 4 adverse events (mainly fatigue, dysphagia, breathlessness, and anorexia) were reported for 13 (57%) CHART and 13 (65%) ICT patients. Conclusions: This small randomized trial indicates that ICT followed by CHART is feasible and well tolerated. Despite closing early because of poor accrual, and so failing to show clear evidence of a survival benefit for the additional chemotherapy, the results suggest that CHART, and ICT before CHART, remain important options for the treatment of inoperable NSCLC and deserve further study.

    Gastric cancer remains a major public health issue and is a leading cause of death worldwide, accounting for 600,000 deaths annually. Over the last decades, there has been a steady decline in the incidence rates of gastric cancer. Furthermore, the incidence rates of gastric cancer in different parts of the country vary due to epidemiological and migration trends. Despite these trends, several studies that have continued to observe high rates of gastric cancer in populations that come from high-risk regions. The aim of the study was to describe the gastric cancer patients presenting NYHQ with an emphasis on those presenting at a young age and advanced disease. A subanalysis of the Asian population was also done, which is considered a high-risk group. Consecutive chart review of patients admitted with gastric cancer from January 2000 to August 2008 was extracted from the Oncology registry at NYHQ. Parameters that were evaluated were age, sex, race, type of gastric cancer, and stage of gastric cancer at initial presentation. The SAS/PC software package (SAS Institute Inc., Cary, NC) was employed for statistical analyses. Four hundred fifty-seven patients were diagnosed with gastric cancer. Approximately one third of the total patients were younger than 60 years of age. Of the Asian patients, almost half the patients (48.8%) had advanced disease of which two thirds were under the age of 60 years. The rates of advanced gastric cancer observed at NYHQ are significant and comparable to recent epidemiology literature on rates in Asian populations in Asia. Communities, like Flushing, NY, may benefit from early detection of gastric cancers, similar to those instituted in Japan and Taiwan.

    Gastric cancer is one of the leading causes of cancer-related deaths in both sexes worldwide, especially in Eastern Asia. This study aimed to estimate the economic burden of advanced gastric cancer (AGC) in Taiwan. The costs of AGC in 2013 were estimated using resource use data from a chart review study (n = 122 with AGC) and national statistics. Annual per-patient costs, where patients' follow-up periods were adjusted for, were estimated with 82 patients who had complete resource use data. The costs were composed of direct medical costs, direct non-medical costs (healthcare travel and caregiver costs), morbidity costs, and mortality costs. Relevant unit costs were retrieved mainly from literature and national statistics, and applied to the resource use data. A broad definition of morbidity and mortality costs was employed to value the productivity loss in patients with unpaid employment, economically inactive and unemployed as well as the life years after the age of retirement. Their narrow definitions were also used in sensitivity analyses, using age- and/or sex-specific employment rates. Forgone future earnings/productivity loss were discounted at 3%. Annual per-patient costs were projected to estimate the total costs of AGC at the national level with an estimated number of patients with AGC (N = 2611) in Taiwan in 2013. The mean age of the 82 patients was 59.3 (SD: 11.9) years, and 67.1% were male. Per-patient costs were US$26,431 for direct medical costs, US$4669 for direct non-medical costs, US$5758 for morbidity costs, and US$145,990 for mortality costs (per death). These per-patient costs were projected to incur total AGC costs of US$423 million at the national-level. Mortality costs accounted for 77.3% of the total costs, followed by direct medical costs (16.3%), morbidity costs (3.6%), and direct non-medical costs (2.9%). AGC was found to exert a significant economic burden in Taiwan, incurring US$423 million in 2013. This represents about 0.08% of

  1. Advances in Understanding How Heavy Metal Pollution Triggers Gastric Cancer

    2016-01-01

    Full Text Available With the development of industrialization and urbanization, heavy metals contamination has become a major environmental problem. Numerous investigations have revealed an association between heavy metal exposure and the incidence and mortality of gastric cancer. The mechanisms of heavy metals (lead, cadmium, mercury, chromium, and arsenic contamination leading to gastric cancer are concluded in this review. There are four main potential mechanisms: (1 Heavy metals disrupt the gastric mucosal barrier by decreasing mucosal thickness, mucus content, and basal acid output, thereby affecting the function of E-cadherin and inducing reactive oxygen species (ROS damage. (2 Heavy metals directly or indirectly induce ROS generation and cause gastric mucosal and DNA lesions, which subsequently alter gene regulation, signal transduction, and cell growth, ultimately leading to carcinogenesis. Exposure to heavy metals also enhances gastric cancer cell invasion and metastasis. (3 Heavy metals inhibit DNA damage repair or cause inefficient lesion repair. (4 Heavy metals may induce other gene abnormalities. In addition, heavy metals can induce the expression of proinflammatory chemokine interleukin-8 (IL-8 and microRNAs, which promotes tumorigenesis. The present review is an effort to underline the human health problem caused by heavy metal with recent development in order to garner a broader perspective.

    The aim of this study was to describe delayed phase dynamic CT findings of advanced (T2-T4) gastric cancer and to correlate with histopathologic findings. Quadruple phase dynamic CT including delayed imaging taken five minutes after the start of injection of contrast material was performed in 43 patients with 45 advanced gastric cancer and 20 control subjects with no gastric lesions. On delayed phase CT scans, the attenuation of the gastric wall was equal to or lower than that of the liver parenchyma in the control subjects, therefore, the presence of higher attenuation in the gastric wall was considered to be abnormal and defined as delayed enhancement. Histopathologic findings in the tumors showing delayed enhancement were compared with those in the tumors without this feature. Delayed enhancement was seen in 26 (57%) of the 45 tumors. Eleven of 25 differentiated-type tumors and 15 of 20 undifferentiated-type tumors showed delayed enhancement (p<.05). Delayed enhancement was seen in one of five medullary type tumors, in 11 of 25 intermediate-type tumors, and in 14 of 15 scirrhous-type tumors (p<.005). Delayed enhancement was frequently seen in the tumors with abundant fibrous tissue stroma. Delayed phase dynamic CT may be useful for the characterization of advanced gastric cancer. (author)

    Background: Overall 5 years survival for surgically excised gastric cancer is 30%. Adjuvant treatment may improve the surgical results. Aim: To assess treatment results and toxicity in patients with surgically excised gastric cancer, treated with adjuvant radiotherapy and concomitant continuous 5-Fluorouracil (5-FU). Material and Methods: Forty one patients aged 32 to 73 years (29 males) with stage II-IVA gastric cancer, subjected to a total or subtotal gastrectomy and D2 nodal dissection between 1997 to 2006, were studied. They received adjuvant radiotherapy to the gastric bed and draining lymphatic nodes in a total dose of 50.4 Gy in 28 fractions and chemotherapy with continuous infusion 5-FU, 200 mg/m2/day. Results were compared to historical controls matched according to demographic parameters and tumor characteristics. Results: Eighteen patients were in stage II, 10 in stage IIIA, nine in stage IIIB and four in stage IVA. Twelve patients had an N0 nodal status, 15 were N1, nine were N2 and five were N3. After a mean follow up of 32 months, 26 patients (63%) were alive. Five year overall survival was 49.6% for surgery plus radiochemotherapy compared to 30.7% for the historical group subjected only to surgery (p =0.002). Radiotherapy was associated with grade 1-2 toxicity and treatment was completed without interruptions in all patients. Chemotherapy was delayed temporarily in 3 patients. Conclusions: Adjuvant radio-chemotherapy improved overall survival in gastric cancer, compared to historical controls subjected only to surgical treatment

    Usefulness of FDG PET CT in monitoring response in locally advanced gastric cancer has been reported. The purpose of this study was to evaluate the related factors to detect measurable diseases in advanced gastric cancer on FDG PET CT. We retrospectively reviewed 38 patients diagnosed as having advanced gastric cancer. We defined the measurable diseases when there was visualized tumor of which maximum standardized uptake value(SUVmax) was higher than 1.35*SUVmax of liver + 2*SD of liver SUV. We evaluated what kinds of factors from the clinicopathologic features were related to identifying measurable diseases. Of 38 patients with advanced gastric cancer, 18 (50%) had measurable tumors on FDG PET CT. Measurable tumors were significantly more frequent in well or moderately differentiated adenocarcinoma (70.5% vs 35.3%, p<0.05), in the tumors located at antrum or angle (66.7% vs 29.4%, p<0.05) and in the elderly group (age of 55 years old or more, 72.0% vs 8.3%, p<0.001) than the others, respectively. By multivariate analysis, age at diagnosis was the only independent predictor for the measurable disease on FDG PET CT. We found that age at diagnosis, as well as histologic types and location of tumors, were the affecting factors to detect measurable disease on FDG PET CT in patients with advanced gastric cancer. Our study suggests that elderly patients of age of 55 years old or more can frequently have T measurable disease on FDG PET CT in advanced gastric cancer and FDG PET CT will be helpful to monitor measurable disease

    Despite advancements in therapy for advanced gastric and gastroesophageal junction cancers, their prognosis remains dismal. Tumor angiogenesis plays a key role in cancer growth and metastasis, and recent studies indicate that pharmacologic blockade of angiogenesis is a promising approach to therapy. In this systematic review, we summarize current literature on the clinical benefit of anti-angiogenic agents in advanced gastric cancer. We conducted a systematic search of PubMed and conference proceedings including the American Society of Clinical Oncology, the European Society for Medical Oncology, and the European Cancer Congress. Included studies aimed to prospectively evaluate the efficacy and safety of anti-angiogenic agents in advanced gastric or gastroesophageal junction cancer. Each trial investigated at least one of the following endpoints: overall survival, progression-free survival/time to progression, and/or objective response rate. Our search yielded 139 publications. Forty-two met the predefined inclusion criteria. Included studies reported outcomes with apatinib, axitinib, bevacizumab, orantinib, pazopanib, ramucirumab, regorafenib, sorafenib, sunitinib, telatinib, and vandetanib. Second-line therapy with ramucirumab and third-line therapy with apatinib are the only anti-angiogenic agents so far shown to significantly improve survival of patients with advanced gastric cancer. Overall, agents that specifically target the vascular endothelial growth factor ligand or receptor have better safety profile compared to multi-target tyrosine kinase inhibitors.

    Histopathologic features could affect the FDG uptake of primary gastric cancer and detection rate on FDG PET/CT. The aim of this study was to evaluate the FDG uptake of primary gastric cancer by correlating it with the histopathologic features of the tumors. Fifty patients with locally advanced gastric adenocarcinoma who were referred for preoperative FDG-PET/CT scans were enrolled in this study. The detection rate of PET/CT and maximum standardized uptake values (SUV max ) of the primary tumor were compared using the WHO, Lauren, Ming and Borrmann classifications and tumor size and location. In 45 of the 50 patients (90 %), the primary gastric tumors were detected by FDG PET/CT. On comparison using the WHO classification, the detection rate and SUV max of the tubular type were significantly higher than those of the poorly cohesive type. On comparison using the Lauren and Ming classifications, the SUV maxs of the intestinal type and expanding type were significantly higher than those of the diffuse and infiltrative type, respectively. On comparison using the Borrmann classification and tumor size and location, there was no significant difference in the detection rate and SUV max of primary gastric tumors. This study demonstrates that the poorly cohesive type according to the WHO classification, diffuse type according to the Lauren classification and infiltrative type according to the Ming classification have low FDG uptake in patients with locally advanced gastric carcinoma. Understanding the relationship between primary tumor FDG uptake and histopathologic features would be helpful in detecting the primary tumor by FDG PET/CT in patients with gastric cancer

    Background: The 5-year survival of patients with completely resected node-positive gastric cancer ranges from 15% to 25%. We explored the feasibility of a chemoradiation regime consisting of concomitant hyperfractionated radiotherapy and 5-fluorouracil protracted venous infusion (5-FU PVI). Materials and Methods: Forty patients received a total or partial gastrectomy operation and D2 nodal resection for Stage III gastric cancer; they were then irradiated by linac with 6-15-MV photons. The target included the gastric bed, the anastomosis, stumps, and regional nodes. A total dose of 55 Gy was given in 50 fractions using 1.1 Gy b.i.d. All patients received a concomitant 200 mg/m2/day 5-FU PVI. Patients were examined during the follow-up period as programmed. Toxicity was recorded according to RTOG criteria. Results: After a median follow-up of 75.6 months (range: 22-136 months), 24 (60%) patients had died, and 16 (40%) were alive and free of disease. The 5-year actuarial incidence of relapse was 39%, 22%, and 2% for distant metastases, out-field peritoneal seeding, and in-field local regional recurrences, respectively. The 5-year actuarial cause-specific survival was 43%. Three patients survived more than 11 years. Acute ≥ Grade 3 toxicity consisted of hematologic (22.5%) and gastrointestinal toxicity (nausea and vomiting 22.5%, diarrhea 2.8%, and abdominal pain 2.6%). No late toxicity was observed. Conclusion: This regime of concomitant 5-FU PVI and hyperfractionated radiotherapy was well tolerated and resulted in successful locoregional control and satisfactory survival

    Patients with cancer are at high risk for thrombotic events, which are known collectively as Trousseau's syndrome. Herein, we report a 66-year-old male patient who was diagnosed with terminal stage gastric cancer and liver metastasis and who had an initial clinical presentation of upper gastrointestinal bleeding. Acute ischemia of the left lower leg that resulted in gangrenous changes occurred during admission. Subsequent angiography of the left lower limb was then performed. This procedure revealed arterial thrombosis of the left common iliac artery with extension to the external iliac artery, the left common iliac artery, the posterior tibial artery, and the peroneal artery, which were occluded by thrombi. Aspiration of the thrombi demonstrated that these were not tumor thrombi. The interesting aspect of our case was that the disease it presented as arterial thrombotic events, which may correlate with gastric adenocarcinoma. In summary, we suggested that the unexplained thrombotic events might be one of the initial presentations of occult malignancy and that thromboprophylaxis should always be considered.

    Objectives: This study was initiated to investigate the feasibility and efficacy of preoperative radiotherapy with weekly paclitaxel and carboplatin in locally advanced gastric cancer. Methods: In a prospective study, patients with locally advanced gastric cancer stage IB-IV(M0) were treated with chemoradiotherapy followed by surgery 4–6 weeks after the last irradiation. Chemoradiotherapy consisted of radiation to a total dose of 45 Gy given in 25 fractions of 1.8 Gy, combined with concurrent weekly carboplatin and paclitaxel. Results: Between December 2007 and January 2012, 25 patients with cT3 (64%) or cT4 (36%) gastric cancer were included. One patient discontinued concurrent chemotherapy in the 4th week due to toxicity, but completed radiotherapy. Another patient discontinued chemoradiotherapy after the 3rd week due to progressive disease. Grade III adverse events of chemoradiotherapy were: gastrointestinal 12%, haematological 12% and other 8%. All patients, except one who developed progressive disease, were operated. Surgical complications were: general/infectious 48%, anastomotic leakage 12%, and bowel perforation 8%. Postoperative mortality was 4%. Microscopically radical resection rate was 72%. Pathological complete response rate was 16% and near complete response rate 24%. Conclusions: In this study, preoperative chemoradiotherapy for patients with locally advanced gastric cancer was associated with manageable toxicity and encouraging pathological response rates.

    The aim of this study was to explore the relationship between nutritional status and expression of RUNX3 in gastric cancer cells and to investigate the effects of nursing strategies on the nutritional status of elderly patients with advanced gastric cancer. Forty-eight elderly patients admitted at Affiliated Hospital of Qingdao University with advanced gastric cancer and 30 healthy controls were selected as subjects from 2014-15. The correlation between RNX3 gene expression and nutritional status of the gastric cancer patients was investigated. The patients with advanced gastric cancer who had low expression of RUNX3 gene were treated with holistic nursing while routine nursing was taken for those patients who had normal or high expression of RUNX3 gene. The nutritional statuses of these patients were evaluated after 3 months of nursing. After a follow-up of 1 year, the influence of different nursing methods on the survival time was evaluated. Compared with normal gastric tissue, the expression of RUNX3 gene and protein in tissues of advanced gastric cancer were significantly decreased ( P nutritional statuses of advanced gastric cancer patients with low expressions of RUNX3 were lower ( P nutritional statuses of patients with low expressions of RUNX3 were notably improved after holistic nursing, becoming equivalent to those with normal or high expression of RUNX3 who received routine nursing ( P >0.05). The survival time of patients with low expression of RUNX3 who received holistic nursing were similar to patients with normal or high expression of RUNX3 who received routine nursing ( P >0.05). RUNX3 is correlated with the occurrence and development of advanced gastric cancer. The low nutritional status of elderly advanced gastric cancer patients with low expressions of RUNX3 can be significantly enhanced by holistic nursing, thereby prolonging survival time.

    We report a case of advanced gastric cancer (AGC) that was resected for rebleeding after palliative radiotherapy for hemostasis. A 74-year-old man with Stage IV gastric cancer received chemotherapy and achieved stable disease. After 23 months, he experienced continuous bleeding from the tumor due to regrowth. Palliative radiotherapy was conducted to control the bleeding, and the tumor successfully achieved hemostasis. However, 6 weeks later, the patient experienced rebleeding and developed hemostatic shock. We then performed a successful emergency gastrectomy. Bleeding negatively affects quality of life in patients with AGC and is potentially lethal. Although palliative radiotherapy for bleeding of gastric cancer is a safe and useful treatment within a short time frame in cases of rebleeding, emergency gastrectomy may be necessary. Therefore, when we select this treatment, the possibility of subsequent surgical treatment must be considered. (author)

    The surgical treatment of gastric cancer has better long-term survival rates when performed in patients with early gastric cancer. Worse results are obtained in treatment of advanced gastric cancer. Most patients in west centers are treated in advanced stages. A great number of them go through a surgical treatment unable by itself to cure them. the frequent local recurrence caused by failure of the surgical treatment has been keeping poor survival rates in patients with advanced gastric cancer for decades. The desire of improving survival is the reason of the use of adjuvant therapies. This paper achieved the retrospective study of the influence of preoperative radiation therapy (2000 cGy) in long-term survival rates (120 months) of patients with advanced gastric cancer on stages IIIa, IIIb and IV. The possible injuries caused in the liver and kidney were observed also as well as first group was treated by surgical and radiation therapies and the second received surgical treatment only. There was no statistical difference between the two groups when sex, age, race, occurrence of other diseases, nutritional assessment, TNM stage, occurrence of obstruction or bleeding caused by tumor, surgical procedure and hepatic and renal function were considered. Survival rates and changes on hepatic and renal function were statistically compared. The results showed a statistic improvement on the long-term survival rates of stage IIIa patients treated by preoperative radiation therapy. No statistic difference was observed on hepatic or renal function between the groups. No adverse influence of radiation therapy method was detected by the used parameters. There was no statistical difference between the two groups when immediate surgical complications were considered. (author)

    For proximal gastric cancer invading the greater curvature, concomitant splenectomy is frequently performed to secure the clearance of lymph node metastases. However, prognostic impact of prophylactic splenectomy remains unclear. The aim of this study was to clarify the oncological significance of prophylactic splenectomy for advanced proximal gastric cancer invading the greater curvature. Retrospective review of 108 patients who underwent total or subtotal gastrectomy for advanced proximal gastric cancer involving the greater curvature was performed. Short-term and long-term outcomes were compared between the patients who underwent splenectomy (n = 63) and those who did not (n = 45). Patients who underwent splenectomy showed higher amount of blood loss (538 vs. 450 mL, p = 0.016) and morbidity rate (30.2 vs. 13.3, p = 0.041) compared with those who did not undergo splenectomy. In particular, pancreas-related complications were frequently observed among patients who received splenectomy (17.4 vs. 0%, p = 0.003). However, no significant improvement of long-term outcomes were confirmed in the cases with splenectomy (5-year recurrence-free rate, 60.2 vs. 67.3%; p = 0.609 and 5-year overall survival rates, 63.7 vs. 73.6%; p = 0.769). On the other hand, splenectomy was correlated with marginally better survival in patients with Borrmann type 1 or 2 gastric cancer (p = 0.072). For advanced proximal gastric cancer involving the greater curvature, prophylactic splenectomy may have no significant prognostic impact despite the increased morbidity rate after surgery. Such surgical procedure should be avoided as long as lymph node involvement is not evident.

    The purpose of this study was to evaluate the performance of multidetector-row CT (MDCT) in the preoperative T-staging of patients with advanced gastric cancer. A total of 65 patients with an established diagnosis of advanced gastric cancer (T2 or more) were evaluated with MDCT. The protocol of MDCT consisted of high-quality (HQ) mode helical scanning with a slice thickness of 2.5 mm. The axial CT images were reconstructed with a slice thickness of 5 mm. MPR images were reconstructed from the raw axial data with a slice thickness of 5 mm. A comparison between the standard axial and axial MPR images was performed by two radiologists with regard to the evaluation of the tumor location and T-stage. These findings were compared with the pathologic and surgical findings. T-staging of the advanced stomach cancer was correct in 89% (58/65) and 69% (45/65) of the MPR images and axial images, respectively. The MPR images improved the detection rate (5 lesions) of the tumors and increased the accuracy of the T-staging (13 lesions) in comparison with the axial images. The MPR images are of greater diagnostic value for the evaluation of omental seeding (5 lesions: axial images, 9 lesions: MPR images), tumor location and extension. Multiplanar reconstruction (MPR) images provide increased confidence in the location and T-staging of certain cases of advanced gastric cancer, such as those in locations where CT images are susceptible to be affected by the difficulties associated with partial volume averaging. In this study, the MPR images provided more precise information about the tumor location and T-staging than the standard axial images in the preoperative evaluation of advanced gastric cancer

From the 2010–2014 we performed 30 surgeries using techniques HICT. Among patients there were 17 men and 13 women. The median of age was 50 years. Locally advanced gastric cancer (T4a-T4b was observed in 22 cases, including 4 patients in the emergency immunocytochemical study with peritoneal lavage detected cancer-free (Cyt + cells in the abdominal cavity. The group of patients with metastatic gastric cancer accounted for 8 patients. Narrow carcinomatosis (P1 was 4 cases, carcinomatosis (P2-P3 — 4. Adjuvant systemic chemotherapy in the study group was not carried out. In the control group No 1 (n = 51 performed surgery alone, without additional anticancer therapy. In the control group No 2 (n = 66, a combined treatment (surgery + chemotherapy. Results. Follow-up median was 25 months. Overall 1-year survival rate for all three groups was 55%, 39% and 52%, respectively. Median survival in the intervention group versus 21.4 months in the 8 and 12 months, respectively. The most effective HICT is shown for patients with locally advanced gastric cancer. In the study group, median overall survival was 29 months. The survival rate of 1-, 2-, 3-year-old was equal to 68%, 61% and 42%. In the first control group, 1-year survival of 45%. None of the patients did not survive 2 years. In the second control group, one-year survival rate was 60%, 2-year survival is not. Results of treatment of metastatic gastric cancer proved to be more modest. In the main group the median survival was 10 months, compared with 6 and 7 months of the two control groups. There were no statistically significant differences. Conclusions. 1. Availability of limited dissemination, free cancer cells in the abdominal cavity, as well as a massive defeat of serous membrane of the stomach can be seen as indications for HICT in gastric cancer. 2.

    To describe treatment patterns, outcomes and healthcare resource use in patients with metastatic and/or locally recurrent, unresectable gastric cancer (MGC) in Taiwan. Patients who had received first-line therapy (platinum and/or fluoropyrimidine) followed by second-line therapy or best supportive care (BSC) only were eligible. Participating physicians provided de-identified information from patient charts. Data were summarized descriptively and Kaplan-Meier analysis was used to describe time to events. Overall, 37 physicians contributed 122 patient charts. Of the 122 patients (median age, 61 years; 62% male), 43 (35%) received BSC only following first-line therapy, whereas 79 (65%) received second-line therapy. There was heterogeneity in second-line treatment, although fluoropyrimidine with or without a platinum agent was most frequently used. Median survival was 12.5 (interquartile range [IQR], 8.2-20.8) months from MGC diagnosis for patients receiving second-line therapy and 8.0 (IQR, 5.6-not reached) months for patients receiving BSC only. The most common treatment-related symptoms were nausea/vomiting (58%); the most common cancer-related symptoms were pain (61%), ascites (35%) and nausea/vomiting (33%). Inpatient and outpatient hospitalizations were numerically more common for patients receiving second-line therapy than for those receiving BSC only; the prevalence of hospice and skilled nursing facility stays were numerically more common for patients receiving BSC only. In this Taiwanese MGC population, 65% received active second-line therapy with heterogeneity seen in the regimen used. Clinical outcomes suggest an unmet medical need in this population. This study may help inform clinical practice and future research to ultimately improve patient outcomes in Taiwan. © 2016 John Wiley & Sons Australia, Ltd.

    To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

Here, we report a case of a 29-year-old pregnant woman at 29 weeks gestation presenting with bilateral solid ovarian masses, which were later diagnosed as metastatic ovarian cancer originating from advanced gastric cancer. This case suggests that Krukenberg tumors should be considered when bilateral ovarian solid masses are encountered regardless of pregnancy

    Gastric cancer is the third leading cause of cancer-related death globally with approximately 723 000 deaths every year. Most patients present with advanced unresectable or metastatic disease, only amenable to palliative systemic treatment and a median survival uncommonly exceeding 12 months. Over the last years, the efficacy of chemotherapy combination has plateaued and the introduction of the anti-human epidermal growth factor receptor 2 trastuzumab has resulted in a limited survival gain in the upfront setting. After this positive experience, first-line treatment with new targeted therapies failed to improve the outcome of advanced gastric cancer. On the contrary, second-line options, including monochemotherapy with taxanes or irinotecan and the anti-vascular endothelial growth factor receptor 2 ramucirumab, either alone or combined with paclitaxel, opened new therapeutic rooms for an ever-increasing number of patients who maintain an acceptable performance status across multiple lines. This article provides an updated overview on the current management of advanced gastric cancer and discusses how the different treatment options available may be best combined to favourably impact the outcome of patients following the logic of a treatment strategy.

    The prognostic nutritional index (PNI) is a useful parameter indicating the immune and nutritional status of cancer patients; this study investigated the prognostic value of the PNI in advanced gastric cancer patients treated with preoperative chemotherapy. We retrospectively reviewed 117 advanced gastric cancer patients who met the inclusion criteria for preoperative chemotherapy and underwent surgical resection from July 2004 to December 2011. The patients were divided into PNI-high (PNI ≥ 45) and PNI-low (PNI  0.05). Cox regression analysis indicated that yield pathologic T (ypT), yield pathologic N (ypN) stage, and prechemotherapy PNI were independent prognostic factors (ypT: HR = 2.914, 95% CI = 1.312-6.470, P = 0.009; ypN: HR = 4.909, 95% CI = 1.764-13.660, P = 0.003; prechemotherapy PNI: HR = 1.963, 95% CI = 1.101-3.499, P = 0.022). The prechemotherapy PNI is a useful predictor of the long-term outcome of patients with advanced gastric cancer treated with preoperative chemotherapy. Copyright © 2016 Elsevier Inc.

    There is strong evidence that tumor growth is not only a result of uncontrolled cell proliferation but also of decreased apoptosis. Caspase-3 is a member of interleukin-1 beta-converting enzyme which is involved in the induction of apoptosis. Data on the expression of caspase-3 in patients with gastric cancer and its association with patient outcome are somewhat contradictory. We aimed to investigate the potential relation of the expression of caspase-3 protein with response to therapy and overall survival in patients with advanced noncardia gastric cancer. Tumor tissue samples collected from 359 consecutive patients with gastric cancer stage IV were retrospectively analyzed for the expression of caspase-3 in the primary tumor. The DNA apoptotic index assessed by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling method. All patients were followed up until death. Caspase-3 was expressed in 43.5 % of tumors. Caspase-3 expression compared to no expression was related with a higher DNA apoptotic index (p gastric cancer is a predictor of poor response to treatment and survival. Further studies are needed to fully elucidate the prognostic value of caspase-3 expression in these patients.

    Purpose: The standard treatment for patients with locally advanced inoperable non-small-cell lung cancer and good prognostic factors has become combined chemotherapy (ChT) and radiotherapy (RT). However, the sequencing of the two modalities, as well as fractionation of RT, has been controversial. The Radiation Therapy Oncology Group (RTOG) Study 92-04 was a randomized Phase II study designed to evaluate further the toxicity and efficacy of 2 different strategies of chemoradiation evaluated in 2 prior RTOG Phase II studies. Methods: Patients with Stage II or III medically inoperable or unresectable non-small-cell lung cancer, good performance status, and minimal weight loss were enrolled into a prospective randomized Phase II RTOG study. Arm 1 consisted of induction ChT (vinblastine 5 mg/m 2 i.v. bolus weekly for the first 5 weeks, and cisplatin, 100 mg/m 2 i.v. on Days 1 and 29) followed by concurrent ChT/RT (cisplatin 75 mg/m 2 i.v. on Days 50, 71, and 92) during thoracic radiotherapy (63 Gy in 34 fractions during 7 weeks starting on Day 50). Arm 2 was concurrent ChT and hyperfractionated RT starting on Day 1 with a total dose of 69.6 Gy in 58 fractions during 6 weeks, 1.2 Gy/fraction b.i.d. ChT consisted of cisplatin, 50 mg/m 2 i.v. on Days 1 and 8, and oral VP-16, 50 mg b.i.d. for 10 days only on the days of thoracic radiotherapy repeated on Day 29. Results: A total of 168 patients were entered between 1992 and 1994, and 163 patients were eligible for analysis. Eighty-one patients were treated in Arm 1 and 82 patients in Arm 2. Pretreatment characteristics, including age, gender, Karnofsky performance status, histologic features, and stage, were similar. The incidence of acute esophagitis was significantly higher among patients treated in Arm 2 than among those treated in Arm 1 (p<0.0001). The incidence of acute hematologic toxicity was significantly higher among patients treated in Arm 1 (p=0.01 for anemia and p=0.03 for other hematologic toxicities) than among

    Full Text Available Background: Gastric cancer is one the most diagnosed cancer and the third leading cause of death from cancer worldwide. As an indicator of antioxidant capacity thiol/disulfide homeostasis regulates detoxification, cell signal mechanisms, apoptosis, transcription and antioxidant defense mechanisms. Disregulation of thiol/disulfide homeostasis identified in other cancer types by recent data. In this study, we aimed to evaluate the thiol/disulfide homeostasis in advanced gastric cancer patients. Methods: The patients who diagnosed with gastric cancer and healthy control subjects were included to study. Serum samples for the thiol-disulphide test were obtained at the time of diagnosis. Thiol-disulphide homeostasis tests were measured by the automated spectrophotometric method. Thiol-disulphide homeostasis was also measured according to clinical and laboratory features. Results: Thirty newly diagnosed advanced gastric adenocarcinoma patients and 28 healthy controls were enrolled in the study. The native thiol (NT and total thiol (TT levels of patients' group were significantly lower compared with controls (p = 0.001 and p < 0.001. In the CEA high (≥5.4 ng/ml group, DS/NT ratio were higher compared with CEA low (<5.4 ng/ml group (p = 0.024. In CA.19-9 high (≥28.3 kU/L group, both DS and DS/NT ratio were significantly higher compared with a CA19-9 low(<28.3 kU/L group (p < 0.05 both. The correlation between CEA and DS levels was also significant (p = 0.02. There was also a positive correlation between CEA levels and DS/NT ratio (p = 0.01. Conclusion: Derangements of thiol/disulfide homeostasis may have a role in gastric cancer pathogenesis and the higher level of oxidative stress may relate to extensive and aggressiveness of the advanced disease. The diagnostic and prognostic values of thiol/disulfide products need to identify with further studies. Keywords: Thiol, Disulfide, Oxidative stress, Gastric cancer, Metastatic

    IL-1beta has been implicated in inflammatory episode. In view of the inflammatory nature of cancer cachexia, we determined the predictive value of IL-1B-31 T/C, -511 C/T, +3954 C/T and IL-1RN VNTR gene polymorphisms on the occurrence of cachexia associated with locally advanced gastric cancer. The study included 214 patients and 230 healthy volunteers. Genomic DNA was prepared from peripheral blood leukocytes. Genotypes and allele frequencies were determined in patients and healthy controls using restriction fragment length polymorphism analysis of polymerase chain reaction products. The overall frequencies of IL-1B-31 T, -511 T, +3954 T and IL-1RN VNTR alleles in patients with locally advanced gastric cancer were all comparable with those in controls. No significant differences were found in the distribution of IL-1B-31 T, -511 T and IL-1RN VNTR between patients with cachexia and without. Patients with cachexia showed a significantly higher prevalence of IL-1B+3954 T allele than those without (P = 0.018). In a logistic regression analysis adjusted for actual weight, carcinoma location and stage, the IL-1B+3954 CT genotype was associated with an odds ratio of 2.512 (95% CI, 1.180 – 5.347) for cachexia. The IL-1B+3954 T allele is a major risk for cachexia from locally gastric cancer. Genetic factors studied are not likely to play an important role in the determination of susceptibility to locally advanced gastric cancer.

    Purpose: To review the outcome of palliative radiotherapy (RT) alone in patients with symptomatic locally advanced or recurrent gastric cancer. Methods and Materials: Patients with symptomatic locally advanced or recurrent gastric cancer who were managed palliatively with RT at Cancer Institute, Singapore were retrospectively reviewed. Study end points included symptom response, median survival, and treatment toxicity (retrospectively scored using the Common Toxicity Criteria v3.0 [CTC]). Results: Between November 1999 and December 2004, 33 patients with locally advanced or recurrent gastric cancer were managed with palliative intent using RT alone. Median age was 76 years (range, 38-90 years). Twenty-one (64%) patients had known distant metastatic disease at time of treatment. Key index symptoms were bleeding (24 patients), obstruction (8 patients), and pain (8 patients). The majority of patients received 30 Gy/10 fractions (17 patients). Dose fractionation regimen ranged from an 8-Gy single fraction to 40 Gy in 16 fractions. Median survival was 145 days, actuarial 12-month survival 8%. A total of 54.3% of patients (13/24) with bleeding responded (median duration of response of 140 days), 25% of patients (2/8) with obstruction responded (median duration of response of 102 days), and 25% of patients (2/8) with pain responded (median duration of response of 105 days). No obvious dose-response was evident. One Grade 3 CTC equivalent toxicity was recorded. Conclusion: External beam RT alone is an effective and well tolerated modality in the local palliation of gastric cancer, with palliation lasting the majority of patients' lives

    Purpose: to test for a possible correlation between high-grade acute organ toxicity during primary radio(chemo)therapy and treatment outcome in patients with locally advanced head and neck squamous cell carcinoma (HNSCC). Patients and methods: from 05/1994 to 01/2009, 216 HNSCC patients were treated with radio(chemo)therapy in primary approach. They received normofractionated (2 Gy/fraction) irradiation including associated nodal drainage sites to a cumulative dose of 70 Gy. 151 patients received additional concomitant chemotherapy (111 patients 5-fluorouracil/mitomycin C, 40 patients cisplatin-based). Toxicity during treatment was monitored weekly according to the Common Toxicity Criteria (CTC), and any toxicity grade CTC {>=} 3 of mucositis, dysphagia or skin reaction was assessed as high-grade acute organ toxicity for later analysis. Results: a statistically significant coherency between high-grade acute organ toxicity and overall survival as well as locoregional control was found: patients with CTC {>=} 3 acute organ toxicity had a 5-year overall survival rate of 4% compared to 8% in patients without (p < 0.01). Thereby, multivariate analyses revealed that the correlation was independent of other possible prognostic factors or factors that may influence treatment toxicity, especially concomitant chemotherapy and radiotherapy technique or treatment-planning procedure. Conclusion: these data indicate that normal tissue and tumor tissue may behave similarly with respect to treatment response, as high-grade acute organ toxicity during radio(chemo)therapy showed to be an independent prognostic marker in the own patient population. However, the authors are aware of the fact that a multivariate analysis in a retrospective study generally has statistical limitations. Therefore, their hypothesis should be further analyzed on biomolecular and clinical levels and other tumor entities in prospective trials. (orig.)

    Full Text Available Despite the great progress in the treatment of gastric cancer, it is still the third leading cause of cancer death worldwide. Patients often miss the opportunity for a surgical cure, because the cancer has already developed into advanced cancer when identified. Compared to best supportive care, chemotherapy can improve quality of life and prolong survival time, but the overall survival is often short. Due to the molecular study of gastric cancer, new molecular targeted drugs have entered the clinical use. Trastuzumab, an antibody targeting human epidermal growth factor receptor 2 (HER2, can significantly improve survival in advanced gastric cancer patients with HER2 overexpression. Second-line treatment of advanced gastric cancer with ramucirumab, an antibody targeting VEGFR-2, alone or in combination with paclitaxel, has been proved to provide a beneficial effect. The VEGFR-2 tyrosine kinase inhibitor, apatinib, can improve the survival of advanced gastric cancer patients after second-line chemotherapy failure. Unfortunately, none of the EGFR targeting antibodies (cetuximab or panitumumab, VEGF targeting monoclonal antibodies (bevacizumab, mTOR inhibitor (everolimus, or HGF/MET pathway targeting drugs has a significant survival benefit. Many other clinical trials based on molecular markers are underway. This review will summarize targeted therapies for advanced gastric cancer.

    We evaluated the impact of neoadjuvant chemoradiotherapy (NACRT) with radio-enhancing S-1 for locally advanced gastric cancer. Patients who had a gastric cancer infiltrating into other organs (T4) or with bulky N2 were enrolled in this study. They received oral S-1 (65 mg/m 2 /day) administration and 50 Gy radiotherapy followed by radical surgery. In 12 subjects (male:female ratio, 7:5; mean age, 70.0 years), 10 (83.3%) completed NACRT and 12 (100%) underwent curative resection. Histopathological efficacy (≥Grade 1b) and down staging were observed 6 patients (75.0%) and 5 (62.5%), respectively, in 8 T4 patients. The efficacy was ≥Grade 2 in all 4 patients with bulky N2. No extra-nodal invasion was noted. In this series 1-and 3-year survival rates were 90.9% and 60.6%, respectively, during a mean observation period of 18.6 months. This procedure is applicable even to hemorrhaging patients. Outstanding antineoplastic effects are expected in locally advanced gastric cancer. (author)

    Objective : To investigate the relationship between the perfusion CT features and the clinicopathologically determined prognostic factors in advanced gastric cancer cases. Materials and Methods : A perfusion CT was performed on 31 patients with gastric cancer one week before surgery using a 16-channel multi-detector CT (MDCT) instrument. The data were analyzed with commercially available software to calculate tumor blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS). The microvessel density (MVD), was evaluated by immunohistochemical staining of the surgical specimens with anti-CD34. All of the findings were analyzed prospectively and correlated with the clinicopathological findings, which included histological grading, presence of lymph node metastasis, serosal involvement, distant metastasis, tumor, node, metastasis (TNM) staging, and MVD. The statistical analyses used included the Student's t-test and the Spearman rank correlation were performed in SPSS 11.5. Result : The mean perfusion values and MVD for tumors were as follows: BF (48.14+/-16.46 ml/100 g/min), BV (6.70+/-2.95 ml/100 g), MTT (11.75+/-4.02 s), PS (14.17+/-5.23 ml/100 g/min) and MVD (41.7+/-11.53). Moreover, a significant difference in the PS values was found between patients with or without lymphatic involvement (p = 0.038), as well as with different histological grades (p 0.04) and TNM stagings (p = 0.026). However, BF, BV, MTT, and MVD of gastric cancer revealed no significant relationship with the clinicopathological findings described above (p > 0.05). Conclusion : The perfusion CT values of the permeable surface could serve as a useful prognostic indicator in patients with advanced gastric cancer

    Full Text Available Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient’s condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

    It is unclear which regimen is the most efficacious among the available therapies for advanced gastric cancer in the second-line setting. We performed a network meta-analysis to determine their relative benefits. We conducted a systematic review of randomized controlled trials (RCTs) through the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases and American Society of Clinical Oncology abstracts up to June 2014 to identify phase III RCTs on advanced gastric cancer in the second-line setting. Overall survival (OS) data were the primary outcome of interest. Hazard ratios (HRs) were extracted from the publications on the basis of reported values or were extracted from survival curves by established methods. A Bayesian network meta-analysis was performed with WinBUGS to compare all regimens simultaneously. Eight RCTs (2439 patients) were identified and contained extractable data for quantitative analysis. Network meta-analysis showed that paclitaxel plus ramucirumab was superior to single-agent ramucirumab [OS HR 0.51, 95 % credible region (CR) 0.30-0.86], paclitaxel (OS HR 0.81, 95 % CR 0.68-0.96), docetaxel (OS HR 0.56, 95 % CR 0.33-0.94), and irinotecan (OS HR 0.71, 95 % CR 0.52-0.99). Paclitaxel plus ramucirumab also had an 89 % probability of being the best regimen among all these regimens. Single-agent ramucirumab, paclitaxel, docetaxel, and irinotecan were comparable to each other with respect to OS and were superior to best supportive care. This is the first network meta-analysis to compare all second-line regimens reported in phase III gastric cancer trials. The results suggest the paclitaxel plus ramucirumab combination is the most effective therapy and should be the reference regimen for future comparative trials.

    The aim of this study was to investigate whether angiogenic factors influence the occurrence of spontaneous apoptosis in advanced gastric cancer. The apoptotic indices (AIs) of 97 tumors from 97 patients with advanced gastric cancer (pT3, pN0, pM0, Stage II) were analyzed by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate biotin nick end labeling (TUNEL) method. Intratumoral microvessel densities (IMVDs) of tumors stained with anti-CD34 monoclonal antibody were quantified under x 200 magnification using computer-assisted image analysis. The expressions of angiogenic factors, such as vascular endothelial growth factor (VEGF), thymidine phosphorylase (dThdPase), transforming growth factor-alpha (TGF-alpha), and p53 were analyzed immunohistochemically and compared with IMVDs and AIs. The mean IMVD of the 97 tumors was 365/mm2 (range 147-990/mm2). The mean AI of tumors was 2.1% (range 0-11.3%). A significant inverse correlation between the AIs and the IMVDs was shown (p = -0.278, P = 0.0064). The mean IMVDs of tumors with high expressions of dThdPase, TGF-alpha, or p53 were significantly higher than those of tumors with low expressions of these factors. The mean AI of tumors with high expressions of dThdPase was significantly lower than that of tumors with low expressions of dThdPase (P = 0.023). However, no significant correlations were detected between AIs and the expression levels of VEGF, TGF-alpha, or p53. In gastric cancer, dThdPase may play an important role in tumor progression by increasing microvessels and by suppressing apoptosis of cancer cells.

    This study aims to provide an overview of different treatment for advanced gastric cancer. In the present study, we systematically reviewed the major findings from relevant meta-analyses. A total of 54 relevant papers were searched via the PubMed, Web of Science, and Google scholar databases. They were classified according to the mainstay treatment modalities such as surgery, chemotherapy and others. Primary outcomes including overall survival, response rate, disease-free survival, recurrence-free survival, progression-free survival, time-to-progression, time-to failure, recurrence and safety were summarized. The recommendations and uncertainties regarding the treatment of advanced gastric cancer were also proposed. It was suggested that laparoscopic gastrectomy was a safe and technical alternative to open gastrectomy. Besides, neoadjuvant chemotherapy and adjuvant chemotherapy were thought to benefit the survival over surgery alone. And it was demonstrated in the study that targeted therapy like anti-angiogenic and anti-HER2 agents but anti-EGFR agent might have a significant survival benefit. PMID:27655725

    To investigate the relationship of prognostic nutritional index (PNI) with clinicopathological factors and the clinical significance of PNI in predicting the survival in patients with advanced gastric cancer. Clinicopathological and follow-up data of 1150 patients with advanced gastric cancer who underwent radical gastrectomy from January 2007 to December 2010 at the Department of Gastrointestinal Surgery, Harbin Medical University Cancer Hospital were analyzed retrospectively. The PNI value was calculated [PNI=absolute value of lymphocyte(10 9 /L)×5 + serum albumin (g/L)] and was grouped according to the mean value of PNI. Relationships of PNI with gender, age, tumor size, depth of invasion, tumor differentiation, tumor stage, tumor location, lymph node metastasis and tumor marker detection level were analyzed. At the same time, for the survival analysis of patients, log-rank method was used for univariate analysis, and Cox method was used for multivariate analysis. Of 1150 cases, 846 were males and 304 were females with an average age of 62 (24 to 88) years. The average maximum diameter of tumor was 5.4(1.0 to 20.0) cm. Tumor of 159 cases located in the gastric fundus, 221 cases in the gastric body, 705 cases in the gastric antrum and 65 cases in the whole stomach. Well differentiated tumors were found in 198 cases and poorly differentiated tumors in 952 cases. As for depth of tumor invasion, 165 cases were T2, 343 cases were T3 and 642 cases were T4. According to TNM stage, 53 cases were stage I(, 397 cases were stage II( and 700 cases were stage III(. The average lymph node metastasis rate was 25.0%, meanwhile lymph node metastasis was N0 in 296 cases, N1 in 246 cases, N2 in 277 cases and N3 in 331 cases. Blood examination showed hemoglobin ≤130 g/L in 544 cases and >130 g/L in 606 cases; carcinoembryonic antigen ≤5 μg/L in 903 cases and >5 μg /L in 247 cases; carbohydrate antigen 19-9 ≤37 kU/L in 927 cases and >37 kU/L in 223 cases.

    Gastric cancer is the fifth most common malignancy and second leading cause of cancer-related mortality. Chemotherapy options for patients who fail first-line treatment are limited. Thus the objective of this study was to assess the cost-effectiveness of second-line treatment options for patients with advanced or metastatic gastric cancer. Cost-effectiveness analysis using a Markov model to compare the cost-effectiveness of six possible second-line treatment options for patients with advanced gastric cancer who have failed previous chemotherapy: irinotecan, docetaxel, paclitaxel, ramucirumab, paclitaxel plus ramucirumab, and palliative care. The model was performed from a third-party payer's perspective to compare lifetime costs and health benefits associated with studied second-line therapies. Costs included only relevant direct medical costs. The model assumed chemotherapy cycle lengths of 30 days and a maximum number of 24 cycles. Systematic review of literature was performed to identify clinical data sources and utility and cost data. Quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs) were calculated. The primary outcome measure for this analysis was the ICER between different therapies, where the incremental cost was divided by the number of QALYs saved. The ICER was compared with a willingness-to-pay (WTP) threshold that was set at $50,000/QALY gained, and an exploratory analysis using $160,000/QALY gained was also used. The model's robustness was tested by using 1-way sensitivity analyses and a 10,000 Monte Carlo simulation probabilistic sensitivity analysis (PSA). Irinotecan had the lowest lifetime cost and was associated with a QALY gain of 0.35 year. Docetaxel, ramucirumab alone, and palliative care were dominated strategies. Paclitaxel and the combination of paclitaxel plus ramucirumab led to higher QALYs gained, at an incremental cost of $86,815 and $1,056,125 per QALY gained, respectively. Based on our prespecified

    Purpose: To analyze the efficacy and toxicity of adjuvant whole abdomen irradiation (WAI) and concomitant chemotherapy in the treatment of completely resected, high-risk gastric cancer. Methods and Materials: Between October 1990 and September 1997, 52 patients with completely resected gastric cancer, with lymph node and/or serosal involvement, were treated. Ages were 16-78 (median, 53.5) years. Treatment was either total- or sub-total gastrectomy, followed by WAI, 2100 cGy/21 fractions plus a 2400 cGy/16 fractions boost to the tumor bed. Chemotherapy consisted of either 5-fluorouracil (5-FU) 450-500 mg/m 2 i.v. for 5 days first and 5th week or 200-300 mg/m 2 continuous infusion during irradiation. No further chemotherapy was given. Results: With a minimum follow-up of 30 months and a median follow-up of 43.5 months, 25 of the 52 patients have died. Overall 5-year survival rate is 54%. Three patients sustained Grade 3-5 complications. Two patients with Grade 5 complications (malabsorption syndrome) died 31 and 56 months after the beginning of the treatment, respectively, with no evidence of recurrent tumor. For patients with involvement of the lymph nodes alone (n=19) the 5-year survival was 69%, which was significantly better than the 36% 5-year survival observed for those patients with both serosal and lymph node involvement (n=26, p=0.004). Conclusion: Adjuvant radiochemotherapy, WAI, and concomitant 5-FU, is a feasible and a fairly well-tolerated treatment for patients with locally advanced (involvement of the lymph nodes or serosa) gastric carcinoma who undergo complete resection. The 54% overall 5-year survival compares favorably with the survival reported after surgery alone for those patients

    Higher morbidity in total gastrectomy than in distal gastrectomy has been reported, but laparoscopic subtotal gastrectomy (LsTG) has been reported to be safe and feasible in early gastric cancer (GC). We determined the surgical, nutritional and oncological outcomes of LsTG for advanced gastric cancer (AGC). Of the 816 consecutive patients with GC who underwent radical gastrectomy at our institution between 2008 and 2012, 253 who underwent curative laparoscopic gastrectomy (LG) for AGC were enrolled. LsTG was indicated for patients with upper stomach third tumors, who hoped to avoid total gastrectomy, nutritional status were primarily assessed. Of 253 patients, the morbidity (Clavien-Dindo classification grade ≥ III) was 17.0% (43 patients). The 3-year overall survival and 3-year recurrence-free survival rates were 80.2 and 73.5%, respectively. LcDG, LsTG and LTG were performed in 121, 27 and 105 patients, individually. Morbidity was strongly associated with LTG (P = 0.001). Postoperative loss of body weight was significantly greater after LTG in comparison with LcDG or LsTG (P nutritional point of view.

    To study the effect of neoadjuvant chemotherapy on nutritional status in patients with locally advanced gastric cancer. Cases inclusion criteria: (1)18-65 years old; (2) Gastric cancer confirmed by gastroscopic biopsy; (3) Preoperative TNM stage III( according to the AJCC stage 2000 standard; (4) Kamosfsky functional status score> 60 points; (5)Receiving neoadjuvant chemotherapy voluntarily and signing the informed consent form. Case exclusion criteria: (1)Having contraindications of chemotherapy and surgery; (2) Suffering from heart, liver and kidney and other underlying diseases; (3) Concurrent with malignant diseases, wasting disease or other digestive diseases. According to the above criteria, clinical data of 73 patients of stage III( gastric cancer receiving neoadjuvant chemotherapy at Weifang People's Hospital from May 2015 to March 2017 were prospectively collected. The cohort study was adopted. After removing 3 patients who did not complete the chemotherapy, a total of 70 patients who completed the chemotherapy were included in the study. All the patients received SOX chemotherapy without nutritional support during chemotherapy. Changes of body composition and nutritional indicators were analyzed before and after chemotherapy, and according to the tumor regression after chemotherapy, patients were divided into response group (complete or sub-total tumor regression) and non-response group (tumor part, with or without a small amount of retreat) for stratified analysis. Of 70 gastric cancer patients, 40 were male and 30 were female with a age of (53.8±6.4) (28 to 64) years. There were 26 cases (37.1%) of stage III(a, 35 cases (50.0%) of stage III(b and 9 cases (12.9%) of stage III(c. There were 41 cases in response group and 29 cases in non-response group. Three patients (4.3%) were complete remission (CR) and 38 patients (54.3%) were partial remission (PR) in response group, while 23 cases (32.9%) were stable disease (SD) and 6 cases (8.6%) were progressive

    Impact of splenic hilar LN dissection during total gastrectomy for proximal advanced gastric cancer is controversial. The objective of this study was to assess the impact on prognosis of splenic hilar lymph node(LN) metastasis compared to that of metastasis to other regional LN groups. Patients who underwent total gastrectomy with D2 LN dissection from 2000 to 2010 were reviewed retrospectively. The clinicopathologic characteristics and long-term results of patients with splenic hilar LN metastasis were compared to those of patients with only metastasis to other extraperigastric LNs (stations #8a, #9, #11, or #12a). To investigate the survival benefit of performing splenic hilar LN dissection, the estimated therapeutic index for the procedure was calculated by multiplying the incidence of metastases in the hilar region by the survival rates for individuals with nodal involvement in that region. Of 602 patients, 87(14.5%) had hilar LN metastasis. The 5-year overall and relapse-free survival rates for patients with hilar LN metastasis were 24.1% and 12.1%, respectively. These rates were similar to those for patients with metastasis to other extraperigastric LNs ( P > 0.05), with similar recurrence patterns. Overall survival in the hilar LN metastasis group was better than that for patients with distant metastasis( P hilar LN dissection was 3.5, which was similar to index values for LN dissection at other extraperigastric LNs. Dissection of splenic hilar LNs during total gastrectomy for advanced gastric cancer allows for a prognosis similar to that achieved with dissection of extraperigastric LNs.

    Purpose: To evaluate the efficacy of intraoperative radiotherapy (IORT) followed by concurrent chemotherapy and external beam RT (EBRT) in the treatment of locally advanced gastric adenocarcinoma. Methods and Materials: A total of 97 consecutive and nonselected patients with newly diagnosed Stage T3, T4, or N+ adenocarcinoma of the stomach underwent gastrectomy with D2 lymph node dissection between March 2003 and October 2005. Of the 97 patients, 51 received adjuvant concurrent chemotherapy (5-fluorouracil, leucovorin, docetaxel, and cisplatin) and EBRT (EBRT group) and 46 received IORT (dose range, 12-15 Gy) immediately after gastrectomy and lymph node dissection before concurrent chemoradiotherapy (EBRT+IORT group). Results: After a median follow-up of 24 months, the 3-year locoregional control rate was 77% and 63% in the two groups with or without IORT, respectively (p = 0.05). The 3-year overall survival and disease-free survival rate was 47% and 36% in the EBRT group and 56% and 44% in the EBRT+IORT group, respectively (p > 0.05). Multivariate analyses revealed that the use of IORT, presence of residual disease after surgery, and pN category were independent prognostic factors for locoregional control and that IORT, pN, and pT categories were independent prognostic factors for overall survival (p < 0.05). Four patients experienced Grade 3 or 4 late complications, but no significant difference was observed between the two groups. Conclusions: Radical gastrectomy with D2 lymph node dissection and IORT followed by adjuvant chemoradiotherapy appeared to be feasible and well-tolerated in the treatment of locally advanced gastric cancer. The addition of IORT to the trimodality treatment significantly improved the 3-year locoregional control rate

    Postoperative/adjuvant radiotherapy of advanced gastric cancer involves a large planning target volume (PTV) with multi-concave shapes which presents a challenge for volumetric modulated arc therapy (VMAT) planning. This study investigates the advantages of automated VMAT planning for this site compared to manual VMAT planning by expert planners. For 20 gastric cancer patients in the postoperative/adjuvant setting, dual-arc VMAT plans were generated using fully automated multi-criterial treatment planning (autoVMAT), and compared to manually generated VMAT plans (manVMAT). Both automated and manual plans were created to deliver a median dose of 45 Gy to the PTV using identical planning and segmentation parameters. Plans were evaluated by two expert radiation oncologists for clinical acceptability. AutoVMAT and manVMAT plans were also compared based on dose-volume histogram (DVH) and predicted normal tissue complication probability (NTCP) analysis. Both manVMAT and autoVMAT plans were considered clinically acceptable. Target coverage was similar (manVMAT: 96.6 ± 1.6%, autoVMAT: 97.4 ± 1.0%, p = 0.085). With autoVMAT, median kidney dose was reduced on average by > 25%; (for left kidney from 11.3 ± 2.1 Gy to 8.9 ± 3.5 Gy (p = 0.002); for right kidney from 9.2 ± 2.2 Gy to 6.1 ± 1.3 Gy (p plans (4.2% and 9.1%, respectively; p plans compared to manVMAT plans, the predicted NTCPs for the left and right kidney and the liver-PTV were significantly reduced by 11.3%, 12.8%, 7%, respectively (p ≤ 0.001). Delivery time and total number of monitor units were increased in autoVMAT plans (from 168 ± 19 s to 207 ± 26 s, p = 0.006) and (from 781 ± 168 MU to 1001 ± 134 MU, p = 0.003), respectively. For postoperative/adjuvant radiotherapy of advanced gastric cancer, involving a complex target shape, automated VMAT planning is feasible and can substantially reduce the dose to the kidneys and the liver

    To evaluate the clinical value of staging laparoscopy in treatment decision-making for advanced gastric cancer (GC). Clinical data of 582 patients with advanced GC were retrospectively analyzed. All patients underwent staging laparoscopy. The strength of agreement between computed tomography (CT) stage, endoscopic ultrasound (EUS) stage, laparoscopic stage, and final stage were determined by weighted Kappa statistic (Kw). The number of patients with treatment decision-changes was counted. A χ(2) test was used to analyze the correlation between peritoneal metastasis or positive cytology and clinical characteristics. Among the 582 patients, the distributions of pathological T classifications were T2/3 (153, 26.3%), T4a (262, 45.0%), and T4b (167, 28.7%). Treatment plans for 211 (36.3%) patients were changed after staging laparoscopy was performed. Two (10.5%) of 19 patients in M1 regained the opportunity for potential radical resection by staging laparoscopy. Unnecessary laparotomy was avoided in 71 (12.2%) patients. The strength of agreement between preoperative T stage and final T stage was in almost perfect agreement (Kw = 0.838; 95% confidence interval (CI): 0.803-0.872; P advanced GC and decrease unnecessary exploratory laparotomy.

    Initial staging of gastric cancer consists of computed tomography (CT) and gastroscopy. In locally advanced (cT3-4) gastric cancer, fluorodeoxyglucose positron emission tomography with CT (FDG-PET/CT or PET) and staging laparoscopy (SL) may have a role in staging, but evidence is scarce. The aim of this study is to evaluate the impact and cost-effectiveness of PET and SL in addition to initial staging in patients with locally advanced gastric cancer. This prospective observational cohort study will include all patients with a surgically resectable, advanced gastric adenocarcinoma (cT3-4b, N0-3, M0), that are scheduled for treatment with curative intent after initial staging with gastroscopy and CT. The modalities to be investigated in this study is the addition of PET and SL. The primary outcome of this study is the proportion of patients in whom the PET or SL lead to a change in treatment strategy. Secondary outcome parameters are: diagnostic performance, morbidity and mortality, quality of life, and cost-effectiveness of these additional diagnostic modalities. The study recently started in August 2017 with a duration of 36 months. At least 239 patients need to be included in this study to demonstrate that the diagnostic modalities are break-even. Based on the annual number of gastrectomies in the participating centers, it is estimated that approximately 543 patients are included in this study. In this study, it is hypothesized that performing PET and SL for locally advanced gastric adenocarcinomas results in a change of treatment strategy in 27% of patients and an annual cost-reduction in the Netherlands of €916.438 in this patient group by reducing futile treatment. The results of this study may be applicable to all countries with comparable treatment algorithms and health care systems. NCT03208621 . This trial was registered prospectively on June 30, 2017.

    Full Text Available Abstract Background Complete remission from advanced-stage synchronous double primary (SDP esophageal and gastric adenocarcinoma by chemotherapy alone is rare. We report a case of advanced-stage SDP esophageal and gastric adenocarcinoma in which a complete response to treatment was obtained with S-1 and cis-diamminedichloroplatinum (CDDP. Case presentation The patient was a 74-year-old man referred to our hospital complaining of dysphagia. Gastrointestinal endoscopy was performed and advanced-stage SDP esophageal and gastric adenocarcinoma diagnosed. Computed tomography revealed multiple regional lymph node metastases in the mediastinum. Neoadjuvant chemotherapy with S-1 and CDDP for advanced esophageal and gastric cancer was planned. An endoscopy following two courses of chemotherapy revealed that the esophageal cancer had been replaced with a normal mucosal lesion and the gastric tumor with a scar lesion; the results of biopsies of both were negative for cancer. Computed tomography revealed that the multiple lymph node metastases had disappeared. We diagnosed a complete response to S-1 and CDDP in advanced-stage SDP esophageal and gastric cancer. The patient is still alive with no signs of recurrence 22 months after the disappearance of the original tumor and metastatic lesions without surgical treatment. Conclusion These results suggest that complete remission from advanced-stage esophageal and gastric cancer can be obtained with chemotherapy with S-1 plus CDDP.

    Gastric cancer is still a major health problem and a leading cause of cancer mortality despite a worldwide decline in incidence. Primarily due to early detection of the disease, the results of treatment for gastric cancer have improved in Japan, Korea and several specialized Western centres. Surgery offers excellent long-term survival results for early gastric cancer (EGC). In the Western world, however more than 80 % of patients at diagnosis have an advanced gastric cancer with a poor prognosis. The aim of surgery is the complete removal of the tumour (UICC R0-resection), which is known to be the only proven, effective treatment modality and the most important treatmentrelated prognostic factor. The prognosis after surgical treatment of gastric cancer remains poor. Neoadjuvant chemotherapy is a rising option in locally advanced gastric cancer. Adjuvant chemoradiation has been shown to be beneficial in gastric cancer patients who have undergone suboptimal surgical resection. The benefits of adjuvant chemotherapy alone seem to be very small, Untreated metastatic gastric cancer is associated with a median survival of only 3 - 4 months, but this can be increased to 8 - 10 months, associated with improved quality of life, with combination chemotherapy. Currently, no standard combination chemotherapy regimen exists, although regimens utilizing both cisplatin and 5-fluorouracil, such as epirubicin/cisplatin/fluorouracil (ECF) or docetaxel/cisplatin/fluorouracil (DCF) are amongst the most active. Newer chemotherapeutic agents, including irinotecan, oxaliplatin and taxanes, show promising activity, and are currently being tested with biologics in clinical trials. (author)

    To evaluate the therapeutic efficacy of percutaneous cryotherapy for inoperable patients with malignant pulmonary nodules. We enrolled 14 patients (7 males, 7 females, average age 68.8 years) who had inoperable lung malignancy in this study from August 2006 through July 2009. We evaluated the therapeutic efficacy of cryotherapy for complete or incomplete ablation by follow up chest CT. Using Kaplan Meier statistical methods, we estimated the survival of patients who had undergone cryotherapy and we investigated post cryotherapy complications. Five of the 14 patients underwent complete ablation (35.7%), while 9 of 14 patients underwent incomplete ablation (64.3%). The change in mean size before procedure and at last follow up CT in the complete and incomplete ablation were as follows: 13.2 {+-} 7.6 mm {yields} 3.8 {+-} 2.7 mm, and 18.1 {+-} 6.2 mm {yields} 33.7 {+-} 17.9 mm, respectively. The median survival of patients in the complete and the incomplete groups were 51.5 months and 24 months, respectively. One patient developed a small pneumothorax, which resolved spontaneously. Two patients developed hemoptysis after the procedure, which was controlled within a day. Percutaneous cryotherapy may be an effective and safe therapeutic method for inoperable patients with malignant pulmonary nodules.

    Gastric cancer is a cause of significant morbidity and cancer-related mortality worldwide. Despite recent advances in targeted therapy and understanding of the biology and development of the malignancy, progress in the treatment of gastric cancer has been limited. Most newly diagnosed patients will present with incurable disease, and have a median survival of less than 1 year. Although the disease has widespread ethnic and epidemiologic differences, medical management of gastric cancer does not distinguish among the various disease subtypes. The recent report of the ToGA phase III study has validated Her2 as a molecular target in this disease, supporting the concept that a greater understanding of the biology of gastric cancer subsets may improve treatment selection and overall outcome of individual patients. This article summarizes the epidemiology and ethnic variation of this disease to crystalize subtypes of gastric cancer in the context of current and future medical management of advanced disease.

    Purpose The oral mammalian target of rapamycin inhibitor everolimus demonstrated promising efficacy in a phase II study of pretreated advanced gastric cancer. This international, double-blind, phase III study compared everolimus efficacy and safety with that of best supportive care (BSC) in previously treated advanced gastric cancer. Patients and Methods Patients with advanced gastric cancer that progressed after one or two lines of systemic chemotherapy were randomly assigned to everolimus 10 mg/d (assignment schedule: 2:1) or matching placebo, both given with BSC. Randomization was stratified by previous chemotherapy lines (one v two) and region (Asia v rest of the world [ROW]). Treatment continued until disease progression or intolerable toxicity. Primary end point was overall survival (OS). Secondary end points included progression-free survival (PFS), overall response rate, and safety. Results Six hundred fifty-six patients (median age, 62.0 years; 73.6% male) were enrolled. Median OS was 5.4 months with everolimus and 4.3 months with placebo (hazard ratio, 0.90; 95% CI, 0.75 to 1.08; P = .124). Median PFS was 1.7 months and 1.4 months in the everolimus and placebo arms, respectively (hazard ratio, 0.66; 95% CI, 0.56 to 0.78). Common grade 3/4 adverse events included anemia, decreased appetite, and fatigue. The safety profile was similar in patients enrolled in Asia versus ROW. Conclusion Compared with BSC, everolimus did not significantly improve overall survival for advanced gastric cancer that progressed after one or two lines of previous systemic chemotherapy. The safety profile observed for everolimus was consistent with that observed for everolimus in other cancers. PMID:24043745

    Background To verify the prognostic value of the pathologic and radiological tumor response after neoadjuvant chemotherapy in the treatment of locally advanced gastric adenocarcinoma. Methods A total of 67 patients with locally advanced gastric cancer (clinical ≥ T2 or nodal disease and without evidence of distant metastases) underwent perioperative chemotherapy (ECF or ECX regimen) from December 2009 through June 2015 in two surgical units. Histopathological and radiological response to chemotherapy were evaluated by using tumor regression grade (TRG) (Becker’s criteria) and volume change assessed by CT. Results Fifty-one (86%) patients completed all chemotherapy scheduled cycles successfully and surgery was curative (R0) in 64 (97%) subjects. The histopathological analysis showed 19 (29%) specimens with TRG1 (less than 10% of vital tumor left) and 25 (37%) patients had partial or complete response (CR) assessed by CT scan. Median disease free survival (DFS) and overall survival (OS) were 25.70 months (range, 14.52–36.80 months) and 36.60 months (range, 24.3–52.9 months), respectively. The median follow up was 27 months (range, 5.00–68.00 months). Radiological response and TRG were found to be a prognostic factor for OS and DFS, while tumor histology was not significantly related to survival. Conclusions Both radiological response and TRG have been shown as promising survival markers in patients treated with perioperative chemotherapy for locally advanced gastric cancer. Other predictive markers of response to chemotherapy are strongly required. PMID:29299362

    Objective: To investigate the effect of postoperative precision nutrition therapy on postoperative recovery (PR) of patients with advanced gastric cancer (AGC) after neoadjuvant chemotherapy (NC). Methods: 71 subjects were randomly divided into 2 groups. The 34 patients of research group were treated with postoperative precision nutrition treatment according to the indirect energy measurement method. The 31 patients of control group were treated with traditional postoperative nutrition treatment. All participants were measured for body mass index (BMI), NRS2002, PG-SGA and relevant laboratory test within the 1st day before surgery and 7th day after surgery. Moreover, the difference between two groups in short-term effects were evaluated. Results: The daily energy supply of control group was 30.1%-43.74% higher than that of the experimental group ( P nutritional risk became lower in the research group ( P recovery of patients in the research group was comparable to that of the control group ( P >0.05). Moreover, the complication rate and hospitalization costs of in research group were significantly lower than that of in control group ( P nutritional risks before surgery, the nutritional index and inflammatory index in the research group were better than those in the control group. Conclusion: Postoperative precision nutrition therapy may improve the postoperative nutritional status and short-term effects of patients with AGC after NC.

    Overcoming tumor heterogeneity is a major challenge for personalized treatment of gastric cancer, especially for human epidermal growth factor receptor-2 targeted therapy. Analysis of circulating tumor DNA allows a more comprehensive analysis of tumor heterogeneity than traditional biopsies in lung cancer and breast cancer, but little is known in gastric cancer. We assessed mutation profiles of ctDNA and primary tumors from 30 patients with advanced gastric cancer, then performed a comprehensive analysis of tumor mutations by multiple biopsies from five patients, and finally analyzed the concordance of HER2 amplification in ctDNA and paired tumor tissues in 70 patients. By comparing with a single tumor sample, ctDNA displayed a low concordance of mutation profile, only approximately 50% (138/275) somatic mutations were found in paired tissue samples, however, when compared with multiple biopsies, most DNA mutations in ctDNA were also shown in paired tumor tissues. ctDNA had a high concordance (91.4%, Kappa index = 0.784, P < 0.001) of HER2 amplification with tumor tissues, suggesting it might be an alternative for tissue. It implied that ctDNA-based assessment could partially overcome the tumor heterogeneity, and might serve as a potential surrogate for HER2 analysis in gastric cancer. © 2017 The Authors.

    Gastric mixed adenoneuroendocrine carcinoma(MANEC)with multiple liver metastases is a rare condition with most data being derived from case reports. We present a case with liver metastases from gastric MANEC that respond remarkably to chemotherapy. Sixty-one-year-old male with severe anemia referred to surgical consultation due to advanced gastric cancer with multiple liver metastases. To relieve uncontrollable tumor bleeding, simple distal gastrectomy for symptom palliation was performed. Based on the tentative diagnosis with gastric poorly differentiated adenocarcinoma, a course of TS-1 and oxaliplatin therapy was administrated. Thereafter final diagnosis with neuroendocrine carcinoma with tubular adenocarcinoma was made, and the chemotherapy was switched to etoposide and cisplatin. Follow up abdominal CT scan after the third course of the therapy showed remarkable tumor shrinkages(PR). In anticipation of the chemotherapy effects in the adjuvant setting, we performed liver metastasectomy for curative intent. Two of 6 resected liver specimens showed no viable cancer cells at all (pCR). However, immediately after the surgery, multiple liver metastases developed, and the recurrent masses had kept growing up rapidly. The third line carboplatin and etoposide chemotherapy was given once but was withdrawn because of bone marrow suppression. At the present, the patient is alive with recurrent diseases for 18 months after initial diagnosis.

    To evaluate the diagnostic value of oblique coronal reconstructed CT images to determine the local invasion of advanced gastric cancer (AGC). Thirty-four consecutive patients, who were suspected to have locally invasive advanced gastric cancer (more than T3 stage) on a preoperative MDCT scan and underwent a diagnostic or curative laparotomy, were enrolled in this study. Two reviewers performed an independent blind review of three series of MDCT images in random order; axial (AXI), conventional coronal (CCI), and oblique coronal (OCI) (parallel to long axis of gastric body and pancreas) images. In assessing the local invasion, the reader's confidence for the local invasion of AGC was graded using a five point scale (1 = definitely negative, 5 = definitely positive: T4). With surgical findings and histopathological proofs as reference standards, the diagnostic performance of the three different plans of CT images was employed for the verification of local invasion of AGC on a preoperative CT scan using the receiver operating characteristic (ROC) method. Agreements between the two reviewers were analyzed using weighted kappa statistics. Results: In 19 out of 34 patients, local invasion was confirmed surgically or histopathologically (13 pancreas invasion, 6 liver invasion, 4 major vascular invasion, 3 colon and mesocolon invasion, and 2 spleen invasion). The diagnostic performance of OCI was superior to AXI or CCI in the local invasion of AGC. The differences in the area under the curve of AXI (0.770 {+-} 0.087, 0.700 {+-} 0.094), CCI (0.884 {+-} 0.058, 0.958 {+-} 0.038), and OCI (0.954 {+-} 0.050, 0.956 {+-} 0.049), were statistically significant for both reviewers. Inter-observer agreement was excellent for OCI ({kappa}= .973), which was greater than CCI (({kappa}= .839), and AXI (({kappa}= .763). On a CT scan, OCI might be a useful imaging technique in evaluating locally invasive advanced gastric cancer.

    The combination of paclitaxel + ramucirumab is a standard second-line treatment in patients with advanced gastric cancer. This therapy has been associated with increased median overall survival and progression-free survival compared with those with paclitaxel monotherapy. We evaluated the cost-effectiveness of paclitaxel + ramucirumab combination therapy in patients with advanced gastric cancer, from the perspective of health care payers in Japan. We constructed a Markov model to compare, over a time horizon of 3 years, the costs and effectiveness of the combination of paclitaxel + ramucirumab and paclitaxel alone as second-line therapies for advanced gastric cancer in Japan. Health outcomes were measured in life-years (LYs) and quality-adjusted (QA) LYs gained. Costs were calculated using year-2016 Japanese yen (¥1 = US $17.79) according to the social insurance reimbursement schedule and drug tariff of the fee-for-service system in Japan. Model robustness was addressed through 1-way and probabilistic sensitivity analyses. The costs and QALYs were discounted at a rate of 2% per year. The willingness-to-pay threshold was set at the World Health Organization's criterion of ¥12 million, because no consensus exists regarding the threshold for acceptable cost per QALY ratios in Japan's health policy. Paclitaxel + ramucirumab combination therapy was estimated to provide an additional 0.09 QALYs (0.10 LYs) at a cost of ¥3,870,077, resulting in an incremental cost-effectiveness ratio of ¥43,010,248/QALY. The incremental cost-effectiveness ratio for the combination therapy was >¥12 million/QALY in all of the 1-way and probabilistic sensitivity analyses. Adding ramucirumab to a regimen of paclitaxel in the second-line treatment of advanced gastric cancer is expected to provide a minimal incremental benefit at a high incremental cost per QALY. Based on our findings, adjustments in the price of ramucirumab, as well as improves in other clinical parameters such as survival

    Carcinoma of the stomach is one of the most prevalent cancer types in the world. Although the incidence of gastric cancer is declining, the outcomes of gastric cancer patients remain dismal because of the lack of effective biomarkers to detect early gastric cancer. Modern biomedical research has explored many potential gastric cancer biomarker genes by utilising serum protein antigens, oncogenic genes or gene families through improving molecular biological technologies, such as microarray, RNA-Seq and the like. Recently, the small noncoding microRNAs (miRNAs) have been suggested to be critical regulators in the oncogenesis pathways and to serve as useful clinical biomarkers. This new class of biomarkers is emerging as a novel molecule for cancer diagnosis and prognosis, including gastric cancer. By translational suppression of target genes, miRNAs play a significant role in the gastric cancer cell physiology and tumour progression. There are potential implications of previously discovered gastric cancer molecular biomarkers and their expression modulations by respective miRNAs. Therefore, many miRNAs are found to play oncogenic roles or tumour-suppressing functions in human cancers. With the surprising stability of miRNAs in tissues, serum or other body fluids, miRNAs have emerged as a new type of cancer biomarker with immeasurable clinical potential.

    Full Text Available Objective: To study the effect of preoperative S-1 combined with regional transcatheter arterial chemoembolization on malignant degree of locally advanced gastric cancer. Methods: A total of 134 patients who were diagnosed with advanced gastric cancer in our hospital from May 2012 to December 2014 were selected for study, received surgical resection after chemotherapy, and were divided into intravenous chemotherapy group and combined treatment group according to different chemotherapy regimens. After chemotherapy and before operation, serum tumor marker levels were detected; after operation, recurrence and metastasis-related molecule levels in tumor tissue were detected. Results: After chemotherapy and before operation, serum CEA, CA199, CA72-4, TSGF, ESM-1 and DKK-1 levels of combined treatment group were significantly lower than those of intravenous chemotherapy group; TET1, TET2, LATS1 and RUNX3 levels in tumor tissue of combined treatment group were higher than those of intravenous chemotherapy group while Sipa1, GOLPH3, AEP, MT2- MMP, OPN, Galectin-1, Galectin-3 and Galectin-9 levels were lower than those of intravenous chemotherapy group. Conclusions: Compared with systemic intravenous chemotherapy, preoperative S-1 combined with regional transcatheter arterial chemoembolization can more effectively kill gastric cancer cells and prevent tumor recurrence and metastasis at molecular level.

    To determine whether multiphasic dynamic CT can preoperatively predict lymphovascular invasion (LVI) in advanced gastric cancer (AGC). 278 patients with AGC who underwent preoperative multiphasic dynamic CT were retrospectively recruited. Tumour CT attenuation difference between non-contrast and arterial (Δ{sub AP}), portal (Δ{sub PP}) and delayed phase (Δ{sub DP}), tumour-spleen attenuation difference in the portal phase (Δ{sub T-S}), tumour contrast enhancement ratios (CERs), tumour-to-spleen ratio (TSR) and tumour volumes were obtained. All CT-derived parameters and clinicopathological variables associated with LVI were analysed by univariate analysis, followed by multivariate and receiver operator characteristics (ROC) analysis. Associations between CT predictors for LVI and histopathological characteristics were evaluated by the chi-square test. Δ{sub PP} (OR, 1.056; 95% CI: 1.032-1.080) and Δ{sub T-S} (OR, 1.043; 95% CI: 1.020-1.066) are independent predictors for LVI in AGC. Δ{sub PP}, Δ{sub T-S} and their combination correctly predicted LVI in 74.8% (AUC, 0.775; sensitivity, 88.6%; specificity, 54.1%), 68.7% (AUC, 0.747; sensitivity, 68.3%; specificity, 69.4%) and 71.7% (AUC, 0.800; sensitivity, 67.6%; specificity, 77.8%), respectively. There were significant associations between CT predictors for LVI with tumour histological differentiation and Lauren classification. Multiphasic dynamic CT provides a non-invasive method to predict LVI in AGC through quantitative enhancement measurement. (orig.)

    The aim of this study was to report the clinical outcome and toxicity of radiochemotherapy in locally advanced gastric cancer (LAGC) patients treated according to the Intergroup 116 trial protocol in our institution. We retrospectively reviewed 105 patients with LAGC treated with radical surgery and adjuvant radiochemotherapy. We analyzed overall survival (OS), disease-free survival (DFS), locoregional failure-free survival (LFS), prognostic factors and toxicity. The mean follow-up was 96.48 months. The majority of tumors were T3-T4 (75%) and 86.6% had nodal metastases. The OS, DFS and LFS rates to 3 years were 53.48%, 52.75% and 81.65%, respectively and to 5 years 40%, 46.73% and 76.77% respectively. The univariate analysis showed that N stage < N2, TN stage < IIIA, R0 resection and N-ratio < 3 were statistically significant prognostic factors for OS and DFS, T stage < T4 for OS and N-ratio < 3 for LFS. The group with D2 lymphadenectomy had worse LFS than the D1 group (65.2% vs 88.1%, respectively, p = 0.039) probably due to a significant difference in the proportion node positive patients in the D2 group (94% vs. 78%; p = 0.027). In the multivariate analysis, only R0 resection was statistically significant factor for improved OS (p = 0.018). Acute grade III-IV gastrointestinal and hematologic toxicity rates were 8.5% and 15.2%, respectively and 89.5% completed treatment as planned. Our results are consistent with those of the Intergroup-0116 trial for LAGC in terms of survival. This regimen is well tolerated and with acceptable toxicity. An R0 resection was an independent prognostic factor for improved OS. (orig.) [de

    A 66-year-old woman was admitted to our clinic for appetite loss and abdominal distension in August 1995. Endoscopic study revealed an advanced gastric cancer in the upper body of her stomach. Abdominal CT study revealed massive ascites and para-aortic lymph nodal involvement. Cytological study of the ascites revealed class V. She was diagnosed to be in the terminal stage of gastric cancer with carcinomatosa peritonitis. Combination chemotherapy with 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) was given by continuous intravenous injection of 5-FU 500 mg/day, and intermittent intravenous injection of CDDP 30 mg/week was performed for reduction of the ascites and her complaint. Endoscopic study 6 weeks after starting chemotherapy could not find crater of the gastric cancer but only a shallow ulcerative lesion. The biopsy specimen of that lesion was group III. No ascites and over 50% reduction of the para-aortic lymph node were found by the abdominal CT study. This state persisted over 4 weeks. No myelo-suppression, renal dysfunction or any severe side effect were observed during chemotherapy. Her performance status improved from 3 to 1.

    Obesity is associated with chronic low-grade inflammation perpetuated by visceral adipose. Other organs, particularly stomach and intestine, may also overproduce proinflammatory molecules. We examined the gene expression patterns in gastric tissue of morbidly obese patients with nonalcoholic fatty liver disease (NAFLD) and compared the changes in gene expression in different histological forms of NAFLD. Stomach tissue samples from 20 morbidly obese NAFLD patients who were undergoing sleeve gastrectomy were profiled using qPCR for 84 genes encoding inflammatory cytokines, chemokines, their receptors, and other components of inflammatory cascades. Interleukin 8 receptor-beta (IL8RB) gene overexpression in gastric tissue was correlated with the presence of hepatic steatosis, hepatic fibrosis, and histologic diagnosis of nonalcoholic steatohepatitis (NASH). Expression levels of soluble interleukin 1 receptor antagonist (IL1RN) were correlated with the presence of NASH and hepatic fibrosis. mRNA levels of interleukin 8 (IL8), chemokine (C-C motif) ligand 4 (CCL4), and its receptor chemokine (C-C motif) receptor type 5 (CCR5) showed a significant increase in patients with advanced hepatic inflammation and were correlated with the severity of the hepatic inflammation. The results of our study suggest that changes in expression patterns for inflammatory molecule encoding genes within gastric tissue may contribute to the pathogenesis of obesity-related NAFLD.

    Epstein-Barr virus-associated gastric cancer (EBVaGC) is one of the four molecular subtypes of gastric cancer, as defined by the classification recently proposed by The Cancer Genome Atlas. We evaluated the correlation between EBV positivity and 18 F-fluorodeoxyglucose ( 18 F-FDG) uptake by positron emission tomography/computed tomography (PET/CT) in patients with gastric cancer. We retrospectively enrolled patients with gastric cancer who underwent pretreatment 18 F-FDG PET/CT and subsequent surgical resection, and then were diagnosed with advanced gastric cancer (pathologic stage ≥T2 with any N stage). Maximum standardized uptake values (SUV max ) of gastric cancer were measured by pretreatment 18 F-FDG PET/CT. EBV sequences were detected by in situ hybridization (ISH) techniques. We analyzed the correlation between EBV positivity, clinicopathologic features and metabolic activity of the primary tumor. A total of 205 patients were included and 15 (7.3%) patients were identified as having EBV-positive gastric cancer. Age, gender, tumor location, and histological type showed no significant differences between EBV-positive and negative groups. EBV-positive cancer is significantly more frequent in the higher-metabolic-tumor group than in the lower one (p=0.032). The mean SUV max of gastric cancers showed significant differences between EBV-positive and negative groups (9.9±4.2 vs. 7.0±4.8, p=0.026). The infection status of EBV was significantly related to the 18 F-FDG uptake of primary tumors in patients with advanced gastric cancer.

    5-Fluorouracil (5-Fu) is one of the most commonly prescribed antineoplastic agents against gastric and colorectal cancers. Continuous infusion would be the optimal way of its administration, however, may usually cause thrombosis, infection, and prolonged hospital stay. Oral fluoropyrimidines would be an attractive alternative, but their efficiency and toxicities for the treatment of gastric and colorectal cancer are still obscure as compared with infusion 5-Fu. Literature retrieval, trials selection and assessment, data collection, and statistic analysis were performed according to the Cochrane Handbook. The outcome measures were tumor response rate, progression-free survival, overall survival, and adverse effects. Twenty-nine randomized controlled trials, comprising totally 15 154 patients, were included. Meta-analysis showed similar overall outcome in terms of response rate (1.01; 95% confidence interval [CI], 0.92-1.12), progression-free survival (hazard ratio 1.00; 95%CI, 0.94-1.06), and overall survival (hazard ratio 0.96; 95%CI, 0.92-1.01) between oral fluoropyrimidine-based and intravenous 5-Fu-based regimens in gastric and colorectal cancer patients. The risk of grade 3/4 neutropenia, thrombocytopenia, and stomatitis was more prominent in intravenous 5-Fu-based regimens; while more frequent grade 3/4 hand-foot syndrome, diarrhea, and anorexia were detected in oral fluoropyrimidine-based regimens. Oral-fluoropyrimidines showed equivalent response and similar survival outcomes, but different toxicity profiles, as compared with intravenous 5-Fu. Thus, it would be a more convenient and adjustable alternative in treatment of advanced gastric and colorectal cancer. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Objective: To study the characteristics of spiral computed tomography (SCT) in the diagnosis of lymph nodes metastases in gastric cancer. Methods: The characteristics of spiral computed tomography (SCT) of metastatic lymph nodes in 35 gastric cancer patients were analyzed and compared with operation and pathology. Results: A total amount of 379 lymph nodes (positive 173, negative 206) were detected by SCT and confirmed by pathology in metastasis-positive or metastasis-negative patients. The positive rate with diameter of lymph nodes ≥ 10 mm is 62.7%. The positive rate with ir- regular shape and uneven enhancement lymph nodes were 96.3% and 89.4%. If the attenuation values, more than or equal to 25 HU in plain scan or 70 HU in arterial phase or 80 HU in venous phase, were used as the threshold to detect the metastasis-positive lymph nodes, the positive rate were 55.7%, 56.3%, 67.8% respectively. Conclusion: SCT is valuable in judging the metastasis in gastric cancer. The reference of diameter ≥ 10mm, combining with the shape and the attenuation values can dramatically improve the diagnosis of lymph node metastasis in gastric cancer. (authors)

    East Asia has higher gastric cancer incidence and mortality rates than other regions. We present a subgroup analysis of East Asians in the positive study RAINBOW. Patients with advanced gastric or gastroesophageal junction adenocarcinoma previously treated with platinum and fluoropyrimidine received ramucirumab 8 mg/kg or placebo on days 1 and 15 plus paclitaxel 80 mg/m(2) on days 1, 8, and 15 of a 28-day cycle. Of 665 intention-to-treat patients, 223 were East Asian. Median overall survival was 12.1 months for ramucirumab plus paclitaxel and 10.5 months for placebo plus paclitaxel (hazard ratio: 0.986, 95% confidence interval: 0.727-1.337, P = 0.929). Median progression-free survival was 5.5 months for ramucirumab plus paclitaxel and 2.8 months for placebo plus paclitaxel (hazard ratio: 0.628, 95% confidence interval: 0.473-0.834, P = 0.001). Objective response rates were 34% for ramucirumab plus paclitaxel and 20% for placebo plus paclitaxel. Grade ≥ 3 neutropenia (60% vs 28%) and leukopenia (34% vs 13%) were higher for ramucirumab plus paclitaxel. The rate of febrile neutropenia was low (4% vs 4%). Special interest adverse events included any grade bleeding/hemorrhage (55% vs 25%), proteinuria (27% vs 7%), and hypertension (22% vs 2%). Ramucirumab plus paclitaxel significantly improves progression-free survival and response rate, with prolonged median overall survival and an acceptable safety profile in East Asians with advanced gastric cancer. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Stress is known to cause severe adverse effects in the human gastrointestinal tract including mucosal microbleedings and erosions or even gastric ulceration but the mechanism of these complications has not been fully elucidated. The pathogenesis of stress-induced gastric damage involves the fall in Gastric Blood Flow (GBF), an increase in gastric acid secretion and gastric motility, enhanced adrenergic and cholinergic nerve activity and the rise in gastric mucosal generation of reactive oxygen species. The gastric mucosal defense mechanisms against the deleterious effect of stress include the activation of the hypothalamic-pituitary-adrenal axis which has been linked with glucocorticoids release capable of counteracting of stress-induced gastric lesions. Here we summarize the novel gastroprotective mechanisms against stress damage exhibited by angiotensin-(1-7), the newly discovered metabolite of Renin-Angiotensin System (RAS), the gaseous mediators such as nitric oxide (NO), hydrogen sulfide (H2S) or Carbon Monoxide (CO), and the food intake controlling peptides ghrelin, nesfatin- 1 and apelin possibly acting via brain-gut axis. These bioactive molecules such as RAS vasoactive metabolite angiotensin-(1-7) and appetite peptides have been shown to afford gastroprotective effect against stressinduced gastric lesions mainly mediated by an increase in gastric microcirculation. Gaseous mediators protect the gastric mucosa against stress lesions by mechanism involving the activation of PG/COX and CO/HO-1 biosynthetic pathways, and their anti-inflammatory and anti-oxidizing properties. Thus, these new components add new mechanistic aspects to the common cooperation of NO/NO-synthase, PG/COX systems and vasoactive sensory neuropeptides including CGRP but their gastroprotective efficacy against experimental stress ulcerogenesis requires the confirmation in human clinical trials.

    Laparoscopy-assisted gastrectomy (LAG) has been established as a low-invasive surgery for early gastric cancer. However, it remains unknown whether it is applicable also for advanced gastric cancer, mainly because the long-term results of LAG with D2 lymph node dissection for advanced gastric cancer have not been well validated compared with open gastrectomy (OG). A retrospective cohort study was performed to compare LAG and OG with D2 lymph node dissection. For this study, 167 patients (66 LAG and 101 OG patients) who underwent gastrectomy with D2 lymph node dissection for advanced gastric cancer were reviewed. Recurrence-free survival and overall survival time were estimated using Kaplan-Meier curves. Stratified log-rank statistical evaluation was used to compare the difference between the LAG and OG groups stratified by histologic type, pathologic T status, N status, and postoperative adjuvant chemotherapy. The adjusted Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) of LAG. The 5-year recurrence-free survival rate was 89.6% in the LAG group and 75.8% in the OG group (nonsignificant difference; stratified log-rank statistic, 3.11; P = 0.0777). The adjusted HR of recurrence for LAG compared with OG was 0.389 [95% confidence interval (CI) 0.131-1.151]. The 5-year overall survival rate was 94.4% in the LAG group and 78.5% in the OG group (nonsignificant difference; stratified log-rank statistic, 0.4817; P = 0.4877). The adjusted HR of death for LAG compared with OG was 0.633 (95% CI 0.172-2.325). The findings show that LAG with D2 lymph node dissection is acceptable in terms of long-term results for advanced gastric cancer cases and may be applicable for advanced gastric cancer treatment.

    The aim of this study was to report the clinical outcome and toxicity of radiochemotherapy in locally advanced gastric cancer (LAGC) patients treated according to the Intergroup 116 trial protocol in our institution. We retrospectively reviewed 105 patients with LAGC treated with radical surgery and adjuvant radiochemotherapy. We analyzed overall survival (OS), disease-free survival (DFS), locoregional failure-free survival (LFS), prognostic factors and toxicity. The mean follow-up was 96.48 months. The majority of tumors were T3-T4 (75%) and 86.6% had nodal metastases. The OS, DFS and LFS rates to 3 years were 53.48%, 52.75% and 81.65%, respectively and to 5 years 40%, 46.73% and 76.77% respectively. The univariate analysis showed that N stage < N2, TN stage < IIIA, R0 resection and N-ratio < 3 were statistically significant prognostic factors for OS and DFS, T stage < T4 for OS and N-ratio < 3 for LFS. The group with D2 lymphadenectomy had worse LFS than the D1 group (65.2% vs 88.1%, respectively, p = 0.039) probably due to a significant difference in the proportion node positive patients in the D2 group (94% vs. 78%; p = 0.027). In the multivariate analysis, only R0 resection was statistically significant factor for improved OS (p = 0.018). Acute grade III-IV gastrointestinal and hematologic toxicity rates were 8.5% and 15.2%, respectively and 89.5% completed treatment as planned. Our results are consistent with those of the Intergroup-0116 trial for LAGC in terms of survival. This regimen is well tolerated and with acceptable toxicity. An R0 resection was an independent prognostic factor for improved OS. (orig.)

    We evaluated the activity of regorafenib, an oral multikinase inhibitor, in advanced gastric adenocarcinoma. We conducted an international (Australia and New Zealand, South Korea, and Canada) randomized phase II trial in which patients were randomly assigned at a two-to-one ratio and stratified by lines of prior chemotherapy for advanced disease (one v two) and region. Eligible patients received best supportive care plus regorafenib 160 mg or matching placebo orally on days 1 to 21 of each 28-day cycle until disease progression or prohibitive adverse events occurred. The primary end point was progression-free survival (PFS). Final analysis included data to December 31, 2014. A total of 152 patients were randomly assigned from November 7, 2012, to February 25, 2014, yielding 147 evaluable patients (regorafenib, n = 97; placebo, n = 50). Baseline characteristics were balanced. Median PFS significantly differed between groups (regorafenib, 2.6 months; 95% CI, 1.8 to 3.1 and placebo, 0.9 months; 95% CI, 0.9 to 0.9; hazard ratio [HR], 0.40; 95% CI, 0.28 to 0.59; P regorafenib was seen (median, 5.8 months; 95% CI, 4.4 to 6.8 v 4.5 months; 95% CI, 3.4 to 5.2; HR, 0.74; P = .147). Twenty-nine patients assigned to placebo received open-label regorafenib after disease progression. Regorafenib toxicity was similar to that previously reported. In this phase II trial, regorafenib was effective in prolonging PFS in refractory advanced gastric adenocarcinoma. Regional differences were found, but regorafenib was effective in both regional groups. A phase III trial is planned. © 2016 by American Society of Clinical Oncology.

    The patient was a 65-year-old woman. She was diagnosed with advanced gastric cancer with liver invasion. After receiving systemic chemotherapy (S-1 plus PTX) for 3 months, she underwent total gastrectomy and partial hepatectomy in May 2008. Because she developed celiac artery circumference lymph node recurrence in November 2010 during postoperative adjuvant chemotherapy consisting of S-1 plus PTX, we changed her chemotherapy regimen to CPT-11 plus CDDP. We observed an increase in the size of the lymph nodes in August 2013 and the response was poor even after switching to DOC. However, the lymph nodes continued to increase in size and we administered radiotherapy of 60.4 Gy/33 Fr that resulted in shrinkage of the nodes. We observed an increase in lymph node size and pancreas invasion in September 2015, including an expansion of the mid pancreatic duct. We performed distal pancreatectomy without identifying the recurrence observed in November 2015 assuming it was an exacerbation. Six months after the surgery, the recurrence was not apparent. We report an example of long-term survival that was achieved for Stage 4 gastric cancer. The patient underwent combined modality therapy for 8 years, and local recurrence was controlled via a primary operation. (author)

    The aim of developing oral fluorouracil (5-FU) is to provide a more convenient administration route with similar efficacy and the best achievable tolerance. S-1, a novel oral fluoropyrimidine, was specifically designed to overcome the limitations of intravenous fluoropyrimidine therapies. A multicentre, randomised phase 3 trial was undertaken to compare S-1/cisplatin (CS) with infusional 5-FU/cisplatin (CF) in 1053 patients with untreated, advanced gastric/gastroesophageal adenocarcinoma. This report discusses a post-hoc noninferiority overall survival (OS) and safety analyses. Results (1029 treated; CS = 521/CF = 508) revealed OS in CS (8.6 months) was statistically noninferior to CF (7.9 months) [hazard ratio (HR) = 0.92 (two-sided 95% confidence interval (CI), 0.80-1.05)] for any margin equal to or greater than 1.05. Statistically significant safety advantages for the CS arm were observed [G3/4 neutropenia (CS, 18.6%; CF, 40.0%), febrile neutropenia (CS, 1.7%; CF, 6.9%), G3/4 stomatitis (CS, 1.3%; CF, 13.6%), diarrhoea (all grades: CS, 29.2%; CF, 38.4%) and renal adverse events (all grades: CS, 18.8%; CF, 33.5%)]. Hand-foot syndrome, infrequently reported, was mainly grade 1/2 in both arms. Treatment-related deaths were significantly lower in the CS arm than the CF arm (2.5% and 4.9%, respectively; Psafety profile and provides a new treatment option for patients with advanced gastric carcinoma.

    Besides representing angiogenesis markers, microvascular density (MVD) and vascular endothelial growth factor (VEGF) are two important tools for the assessment of prognosis in patients with gastric cancer. The aim of our study was to assess the Doppler parameters (resistivity and pulsatility indexes) and vascularity index (VI) calculated by contrast-enhanced power Doppler endoscopic ultrasound (CEPD-EUS) in correlation with the expression of intra-tumoral MVD and VEGF in patients with gastric cancer. The study included 20 consecutive patients with advanced gastric carcinoma, but without distant metastasis at initial assessment. All the patients were assessed by contrast-enhanced power Doppler endoscopic ultrasound (EUS) combined with pulsed Doppler examinations in the late venous phase. The vascularity index (VI) was calculated before and after injection of second generation microbubble contrast specific agent (SonoVue 2.4 mL), used as a Doppler signal enhancer. Moreover, pulsed Doppler parameters (resistivity and pulsatility indexes) were further calculated. The correlation between power Doppler parameters and pathological/molecular parameters (MVD assessed through immunohistochemistry with CD31 and CD34, as well as VEGF assessed through real-time PCR) was assessed. Kaplan-Meier survival analysis was used for the assessment of prognosis. Significantly statistical correlations were found between post-contrast VI and CD34 (p=0.0226), VEGF (p=0.0231), VEGF-A (p=0.0464) and VEGF-B (p=0.0022) while pre-contrast VI was correlated only with CD34 expression. Pulsatility index and resistivity index were not correlated with MVD or VEGF expression. Survival analysis demonstrated that VEGF-A is an accurate parameter for survival rate (p=0.045), as compared to VEGF (p=0.085) and VEGF-B (p=0.230). We did not find any correlation between the survival rate and ultrasound parameters (RI, PI, pre-contrast VI or post-contrast VI). Assessment of tumor vascularity using contrast

    Full Text Available Introduction. Uterine fibroid tumors (uterine leiomyomas are the most common benign uterine tumors. The incidence of uterine fibroid tumors increases in older women and may occur in more than 30% of women aged 40 to 60. Many uterine fibroid tumors are asymptomatic and are diagnosed incidentally. Case Presentation. A 44-year-old woman was admitted to our hospital with general weakness, dyspepsia, abdominal distension, and a palpable abdominal mass. An abdominal computed tomography scan showed a huge tumor mass in the abdomen which was compressing the intestine and urinary bladder. Gastroduodenal endoscopic and biopsy results showed a Borrmann type IV gastric adenocarcinoma. The patient was diagnosed with gastric cancer with disseminated peritoneal carcinomatosis. She underwent a hysterectomy with both salphingo-oophorectomy and bypass gastrojejunostomy. Simultaneous uterine fibroid tumor with other malignancies is generally observed without resection. But in this case, a surgical resection was required to resolve an intestinal obstruction and to exclude the possibility of a metastatic tumor. Conclusion. When a large pelvic or ovarian mass is detected in gastrointestinal malignancy patients, physicians try to exclude the presence of a Krukenberg tumor. If the tumors cause certain symptoms, surgical resection is recommended to resolve symptoms and to exclude a metastatic tumor.

    Full Text Available Introduction. Still there is no consensus on the choice of the most efficient and the least toxic chemotherapy regimen in the treatment of advanced gastric cancer. Nowadays few therapy protocols are available for treating this disease. Objective. Study was conducted to compare the efficacy and toxicity of FAM (flurouracil, doxorubicin, mitomycin C with CDDP and FU/FA (cisplatin, 5-fluorouracil, leucovorin protocols in patients with locally advanced and metastatic gastric cancer. Methods. This randomized study involved a group of 50 patients with locally advanced or metastatic gastric cancer, who had not previously undergone chemotherapy treatment. Progression free survival, overall survival and drug toxicity were evaluated. For statistical analysis chi-square test, Kaplan-Meier curve and the log rank test were used. Results. The overall response rate was 20% in the group treated with FAM and 24% in the group treated with CDDP, FU/FA (4% of patients from each group had complete response, but without significant statistical difference. Median survival was 10.9 months in the FAM group and 11.8 months in CDDP, FU/FA group, with no statistically significant difference. Non-haematological and haematological toxicities of CDDP, FU/FA were considerably less frequent than of FAM, and there was no treatment related deaths in any of the groups. Conclusion. Both investigated regimens demonstrated moderate efficacy. The study shows in favour of justified application of both protocols, while in regard to toxicity CDDP and FU/FA can be recommended as preferable treatment for locally advanced and metastatic gastric cancer. New strategies should be considered for better efficacy in the treatment of advanced gastric cancer. New strategies are necessary with the goal to achieve a better therapeutic effect.

    An inflammatory myofibroblastic tumour (IMFT) is a rare mesenchymal neoplasm characterised by anaplastic lymphoma kinase (ALK) gene rearrangements. We assessed the activity and safety of crizotinib, a tyrosine kinase inhibitor, targeting ALK in patients with advanced IMFT either with or without ALK alterations. We did a multicentre, biomarker-driven, single-drug, non-randomised, open-label, two-stage phase 2 trial (European Organisation for Research and Treatment of Cancer 90101 CREATE) at 13 study sites (five university hospitals and eight specialty clinics) in eight European countries (Belgium, France, Germany, Italy, Netherlands, Poland, Slovakia, and the UK). Eligible participants were patients aged at least 15 years with a local diagnosis of advanced or metastatic IMFT deemed incurable with surgery, radiotherapy, or systemic therapy; measurable disease; an Eastern Cooperative Oncology Group performance status of 0-2; and adequate haematological, renal, and liver function. Central reference pathology was done for confirmation of the diagnosis, and ALK positivity or negativity was assessed centrally using immunohistochemistry and fluorescence in-situ hybridisation based on archival tumour tissue and defined as ALK immunopositivity or rearrangements in at least 15% of tumour cells. Eligible ALK-positive and ALK-negative patients received oral crizotinib 250 mg twice per day administered on a continuous daily dosing schedule (the duration of each treatment cycle was 21 days) until documented disease progression, unacceptable toxicity, or patient refusal. If at least two of the first 12 eligible and assessable ALK-positive patients achieved a confirmed complete or partial response according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, a maximum of 35 patients were to be enrolled. If at least six ALK-positive patients achieved a confirmed response, the trial would be deemed successful. The primary endpoint was the proportion of patients who achieved

    Sorafenib is the recommended treatment for patients with advanced hepatocellular carcinoma. We aimed to compare the efficacy and safety of sorafenib to that of selective internal radiotherapy (SIRT) with yttrium-90 ( 90 Y) resin microspheres in patients with hepatocellular carcinoma. SARAH was a multicentre, open-label, randomised, controlled, investigator-initiated, phase 3 trial done at 25 centres specialising in liver diseases in France. Patients were eligible if they were aged at least 18 years with a life expectancy greater than 3 months, had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, Child-Pugh liver function class A or B score of 7 or lower, and locally advanced hepatocellular carcinoma (Barcelona Clinic Liver Cancer [BCLC] stage C), or new hepatocellular carcinoma not eligible for surgical resection, liver transplantation, or thermal ablation after a previously cured hepatocellular carcinoma (cured by surgery or thermoablative therapy), or hepatocellular carcinoma with two unsuccessful rounds of transarterial chemoembolisation. Patients were randomly assigned (1:1) by a permutated block method with block sizes two and four to receive continuous oral sorafenib (400 mg twice daily) or SIRT with 90 Y-loaded resin microspheres 2-5 weeks after randomisation. Patients were stratified according to randomising centre, ECOG performance status, previous transarterial chemoembolisation, and presence of macroscopic vascular invasion. The primary endpoint was overall survival. Analyses were done on the intention-to-treat population; safety was assessed in all patients who received at least one dose of sorafenib or underwent at least one of the SIRT work-up exams. This study has been completed and the final results are reported here. The trial is registered with ClinicalTrials.gov, number NCT01482442. Between Dec 5, 2011, and March 12, 2015, 467 patients were randomly assigned; after eight patients withdrew consent, 237 were assigned to

    The safety and efficacy of radical laparoscopic distal gastrectomy (LG) with D2 lymphadenectomy for the treatment of advanced gastric cancer (AGC) remain controversial. We conducted a randomized controlled trial to compare laparoscopic and conventional open distal gastrectomy with D2 lymph node dissections for AGC. Between September 2012 and December 2014, 1,056 patients with clinical stage T2-4aN0-3M0 gastric cancer were eligible for inclusion. They were randomly assigned to either the LG with D2 lymphadenectomy group (n = 528) or the open gastrectomy (OG) with D2 lymphadenectomy group (n = 528). Fifteen experienced surgeons from 14 institutions in China participated in the study. The morbidity and mortality within 30 days after surgery between the LG (n = 519) and the OG (n = 520) groups were compared on the basis of the modified intention-to-treat principle. Postoperative complications were stratified according to the Clavien-Dindo classification. The compliance rates of D2 lymphadenectomy were similar between the LG and OG groups (99.4% v 99.6%; P = .845). The postoperative morbidity was 15.2% in the LG group and 12.9% in OG group with no significant difference (difference, 2.3%; 95% CI, -1.9 to 6.6; P = .285). The mortality rate was 0.4% for the LG group and zero for the OG group (difference, 0.4%; 95% CI, -0.4 to 1.4; P = .249). The distribution of severity was similar between the two groups (P = .314). Experienced surgeons can safely perform LG with D2 lymphadenectomy for AGC. © 2016 by American Society of Clinical Oncology.

    AIM: To evaluate the efficacy and toxicity of postoperative chemoradiation using FP chemotherapy and oral capecitabine during radiation for advanced gastric cancer following curative resection. METHODS: Thirty-one patients who had underwent a potentially curative resection for Stage III and IV (M0) gastric cancer were enrolled. Therapy consists of one cycle of FP (continuous infusion of 5-FU 1000 mg/m2 on d 1 to 5 and cisplatin 60 mg/m2 on d 1) followed by 4500 cGy (180 cGy/d) with capecitabine (1650 mg/m2 daily throughout radiotherapy). Four wk after completion of the radiotherapy, patients received three additional cycles of FP every three wk. The median follow-up duration was 22.2 mo. RESULTS: The 3-year disease free and overall survival in this study were 82.7% and 83.4%, respectively. Four patients (12.9%) showed relapse during follow-up. Eight patients did not complete all planned adjuvant therapy. Grade 3/4 toxicities included neutropenia in 50.2%, anemia in 12.9%, thrombocytopenia in 3.2% and nausea/vomiting in 3.2%. Neither grade 3/4 hand foot syndrome nor treatment related febrile neutropenia or death were observed. CONCLUSION: These preliminary results suggest that this postoperative adjuvant chemoradiation regimen of FP before and after capecitabine and concurrent radiotherapy appears well tolerated and offers a comparable toxicity profile to the chemoradiation regimen utilized in INT-0116. This treatment modality allowed successful loco-regional control rate and 3-year overall survival. PMID:16489675

    Full Text Available Abstract Monoclonal antibodies and small molecule tyrosine kinase inhibitors (TKIs directed against the vascular endothelial growth factor (VEGF or its receptors have been investigated in several studies for the treatment of advanced gastric cancer (GC. In the present study, we aimed to evaluate the efficacy and safety of angiogenesis inhibitors in advanced GC. We searched published randomized controlled trials (RCTs comparing angiogenesis inhibitors with non-angiogenesis inhibitors for the treatment of GC. MEDLINE, EMBASE, and the Cochrane Controlled Trials Register were searched. The extracted data on progression-free survival (PFS and overall survival (OS were measured in terms of hazard ratios (HR and corresponding 95 % confidence intervals (CIs. In addition, risk ratios (RR and corresponding 95 % CIs were pooled for objective response rate (ORR, disease control rate (DCR, and risk of adverse events (AEs. Ten RCTs involving 2786 patients were included. Compared with non-angiogenesis inhibitor-containing regimens, angiogenesis inhibitor-containing regimens resulted in a significant improvement in OS (HR 0.80, 95 % CI 0.69–0.93, P = 0.004, prolonged PFS (HR 0.66, 95 % CI 0.51–0.86, P = 0.002, and superior ORR (RR 1.34, 95 % CI 1.09–1.65, P = 0.005 and DCR (RR 1.37, 95 % CI 1.17–1.61, P = 0.0001. Angiogenesis inhibitors were associated with a greater number of AEs, but most of these were predictable and manageable. However, hand-foot syndrome, diarrhea, and gastrointestinal (GI perforation were significantly increased in patients treated with angiogenesis inhibitors. In summary, angiogenesis inhibitor-containing regimens were superior to non-angiogenesis inhibitor-containing regimens in terms of OS, PFS, RR, and DCR in patients with advanced GC.

    The present study was conducted to investigate the prognosis and survival of patients with locally advanced gastric cancer who underwent distal subtotal gastrectomy with modified D2 (D1+) and D2 lymphadenectomy, under 70 years of age. The five-year overall survival rates of 390 patients were compared between those receiving D1+ and D2 lymphadenectomy. Univariate and multivariate analyses were used to identify factors that correlated with prognosis and lymph node metastasis. Tumor size (P=0.039), pT stage (P=0.011), pN stage (PD2 lymphadenectomy removes sufficient lymph nodes to improve staging accuracy and survival. Therefore, D2 lymphanectomy is recommended in distal subtotal gastrectomy for locally advanced gastric cancer, especially for cancers of larger size and higher pT stage.

    In advanced gastric cancer, doublet regimen including platinum salts and fluoropyrimidine is considered as a standard first-line treatment. The addition of docetaxel (75 mg/m 2  q3w) to cisplatin (75 mg/m 2  q3w) and 5-fluorouracil has been shown to improve efficacy. However, this regimen (DCF) was associated with frequent severe toxicities (including more complicated neutropenia), limiting its use in clinical practice. Interesting alternative docetaxel-based regimens have been developed that need to be validated. GASTFOX study is a randomized phase III trial comparing FOLFOX alone or with docetaxel at 50 mg/m 2 (TFOX regimen) in first-line treatment for advanced gastric cancer. In both arms, cycle is repeated every 2 weeks until disease progression or unacceptable toxicity. Main eligibility criteria: histologically proven locally advanced or metastatic gastric or esogastric junction adenocarcinoma, HER negative status, measurable disease, ECOG performance status 0 or 1, and adequate renal, hepatic and bone marrow functions. The primary endpoint is radiological/clinical progression-free survival (PFS). A difference of 2 months for the median PFS in favor of TFOX is expected (HR = 0.73) Based on a two-sided α risk of 5% and a power of 90%, 454 events are required to show this difference. Secondary endpoints included overall survival, overall response rate, safety, quality of life and the therapeutic index. This study is planned to include 506 patients to demonstrate the superiority of TFOX over FOLFOX in first-line advanced gastric cancer treatment (NCT03006432).

    A total of 136 cases with gastric cancer was treated with radiation and some anti-cancer drugs. The tumor responded markedly to radiation in 37% of 92 cases, irradiated more than 5000 rad and regressed completely in only 5% of them. Out of them, the permanent cure was achieved in 3% of T2-4 M0 cases. Serious complications, such as hemorrhagic gastritis, massive bleeding, chronic ulcer of the stomach and perforation, were also observed in a few per cent of them. It was suggested that in the treatment of inoperable gastric cancer, the combination treatment of radiation and chemotherapy should be chosen as a valuable therapeutic procedure to get a good palliation.

    To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and efficacy of sorafenib in combination with FOLFOX4 (oxaliplatin/leucovorin (LV)/5-fluorouracil) as first-line treatment for advanced gastric cancer, we performed a phase I dose-finding study in nine evaluable patients with unresectable locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma. According to modified Fibonacci method, the design of this study was to guide elevation of the sorafenib dosage to the next level (from 200 mg twice daily to 400 mg twice daily and then, if tolerated, 600 mg twice daily). If the patient achieved complete response (CR), partial response (PR) or stable disease (SD) after eight cycles of treatment, combination chemotherapy was scheduled to be discontinued and sorafenib monotherapy continued at the original dose until either disease progression or unacceptable toxicity. In sorafenib 200 mg twice daily group, DLT was observed in 1 of 6 patients, and in 400 mg twice daily group, it was observed in 2 of 3 patients. Seven of 9 (77.8%) evaluable patients achieved PR, with a median overall survival (OS) of 11.8 [95% confidence interval (CI): 8.9-14.7] months. Common adverse effects include hand-foot syndrome, leukopenia, neutropenia, anorexia, and nausea. Twice-daily dosing of sorafenib 200 mg in combination with FOLFOX4 was proven effective and safe for the treatment of advanced gastric cancer, and could be an appropriate dosage for subsequent phase II clinical studies.

    To determine whether immune-enhanced enteral nutrition (EN) was effective on nutritional status, immune function, surgical outcomes and days of hospitalization after total gastrectomy for patients with advanced gastric cancer (AGC). From August 2005 to May 2011, 78 patients with AGC who underwent a total gastrectomy were enrolled and divided randomly into three groups: immune-enhanced EN (EN + glutamine [Gln]) group, standard EN group and control group. Serum parameters including total protein, albumin, proalbumin and transferrin were examined on preoperative day 1, postoperative day 2 and day 12. Levels of immunoglobulin M (IgM), immunoglobulin G (IgG), natural killer (NK) cells, CD4⁺ and CD8⁺ T cells were also compared. The formulas were tolerated well in all the patients except 5 with mild complications. The EN + Gln and EN groups showed a faster onset of flatus and shorter hospitalization duration than the control group. On postoperative day 12, serum total protein, albumin, proalbumin and transferrin levels of the EN + Gln and EN groups were significantly higher than those of the control group (P nutritional status and immune function for the patients with AGC after total gastrectomy. © 2012 The Authors.

    No standard treatment has been accepted widely for the first-/second-line therapy for advanced gastric cancer (AGC). The current study aimed to determine a preferred strategy between FOLFIRI (fluorouracil, leucovorin, and irinotecan) and ECX (epirubicin, cisplatin,and capecitabine) for AGC from the cost-effectiveness perspective. According to a French intergroup study, two groups (ECX arm and FOLFIRI arm) and three health states (progression-free survival (PFS), progressive disease (PD) and death) were analyzed in the current Markov model. All the medical costs were calculated from a Chinese societal perspective. Although FOLFIRI was an acceptable first-line therapy in the treatment of AGC with a better time-to treatment failure (TTF) compared to ECX, ECX arm (ECX followed by FOLFIRI) gained 0.08 quality-adjusted life months (QALMs) more effectiveness benefit compared with FOLFIRI arm (FOLFIRI followed by ECX). Additionally, a lower cost was found in ECX arm ($23,813.13 versus $24,983.70). Hence, the strategy of FOLFIRI arm is dominated by ECX arm ($4,125.8 per QALM in FOLIRI arm; $3,879.724 per QALM in ECX arm). ECX followed by FOLFIRI was a preferred strategy with more effectiveness and lower cost compared with FOLFIRI followed by ECX for the treatment of AGC. PMID:27824060

    Full Text Available Gastric carcinoma is extremely rare in children representing only 0.05% of all gastrointestinal malignancies. Here, we report the first pediatric case of gastric cancer presenting with gastric outlet obstruction. Upper endoscopy revealed a markedly thickened antral mucosa occluding the pylorus and a clean base ulcer 1.5 cm × 2 cm at the lesser curvature of the stomach. The narrowed antrum and pylorus underwent balloon dilation, and biopsy from the antrum showed evidence of Helicobacter pylori gastritis. The biopsy taken from the edge of the gastric ulcer demonstrated signet-ring-cell type infiltrate consistent with gastric adenocarcinoma. At laparotomy, there were metastases to the liver, head of pancreas, and mesenteric lymph nodes. Therefore, the gastric carcinoma was deemed unresectable. The patient died few months after initiation of chemotherapy due to advanced malignancy. In conclusion, this case report underscores the possibility of gastric adenocarcinoma occurring in children and presenting with gastric outlet obstruction.

    The aim is to evaluate the preliminary efficacy and side effects of paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy in combination with cisplatin hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) as postoperative adjuvant therapy for patients of locally advanced gastric cancer (GC) at high risk for recurrence after curative resection. Four GC patients who underwent radical gastrectomy with D2 lymphadenectomy were enrolled. All patients received paclitaxel 135 mg/m2 on day 1, 5-FU 500 mg/m2 on days 1-5, LV 200 mg/m2 on days 1-5 intravenous chemotherapy, cisplatin 75 mg/m2 on day 5, and HIPEC one month after surgery. It was repeated at 3 weeks intervals and at least two cycles administered. A total of 181 cycles of chemotherapy were administered (median, 4 cycles). The median disease free survival time of patients was 40.8 months. The median overall survival time was 48.0 months. The one-, two-, and three-year recurrence rates were 14.6%, 26.8%, and 46.3%, respectively. The main relapse patterns were remnant GC and metastases of retroperitoneal lymph nodes. The morbidity of grade 3 and 4 toxicities of myelosuppression, nausea/ vomiting were less than 10%. The side effects of grade 1 and 2 of hematologic toxicity, nausea and vomiting, abnormal function of liver, kidney or cardiac, fatigue and neurotoxicity were well tolerated. Cisplatin HIPEC combined with paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy regimen could improve the survival rate and decrease the postoperative recurrence of locally advanced GC.

    Purpose: In a retrospective analysis, adjuvant intensity-modulated radiation therapy (IMRT) combined with modern chemotherapy improved advanced gastric cancer survival rates compared to a combination of three-dimensional conformal radiation therapy (3D-CRT) and conventional chemotherapy. We report on the long-term outcomes of two consecutive patient cohorts that were treated with either IMRT and intensive chemotherapy, or 3D-CRT and conventional chemotherapy. Patients and methods: Between 2001 and 2008, 65 consecutive gastric cancer patients received either 3D-CRT (n = 27) or IMRT (n = 38) following tumor resection. Chemotherapy comprised predominantly 5-fluorouracil/folinic acid (5-FU/FA) in the earlier cohort and capecitabine plus oxaliplatin (XELOX) in the latter. The primary endpoints were overall survival (OS) and disease-free survival (DFS). Results: Median OS times were 18 and 43 months in the 3D-CRT and IMRT groups, respectively (p = 0.0602). Actuarial 5-year OS rates were 26 and 47 %, respectively. Within the IMRT group, XELOX gave better results than 5-FU/FA in terms of OS, but this difference was not statistically significant. The primary cause of death in both groups was distant metastasis. Median DFS times were 14 and 35 months in the 3D-CRT and IMRT groups, respectively (p = 0.0693). Actuarial 5-year DFS rates were 22 and 44 %, respectively. Among patients receiving 5-FU/FA, DFS tended to be better in the IMRT group, but this was not statistically significant. A similar analysis for the XELOX group was not possible as 3D-CRT was almost never used to treat these patients. No late toxicity exceeding grade 3 or secondary tumors were observed. Conclusion: After a median follow-up period of over 5 years, OS and DFS were improved in the IMRT/XELOX treated patients compared to the 3D-CRT/5-FU/FA group. Long-term observation revealed no clinical indications of therapy-induced secondary tumors or renal toxicity. (orig.)

    Chemotherapy is a cornerstone in treatments of gastric cancer, but despite its benefit, less than 60% of patients receive salvage therapy in clinical practice. We performed a systematic review and meta-analysis based on trial data on the role of second-line treatment of advanced gastric cancer. MEDLINE/PubMed and Cochrane Library were searched for randomized phase III trials that compared active therapy to best supportive care in advanced gastric cancer. Data extraction was conducted according to the PRISMA statement. Summary HR for OS was calculated using a hierarchical Bayesian model and subgroup analysis was performed based on baseline Eastern Cooperative Oncology Group Performance Status (ECOG) performance status (0 vs. 1 or more). A total of 1,407 patients were evaluable for efficacy, 908 were treated in the experimental arms, with chemotherapy (231 pts) or with targeted therapies (677 pts). The risk of death was decreased by 18% (HR = 0.82; 95% CI, 0.79-0.85; posterior probability HR≥1: Chemotherapy and ramucirumab were able to decrease this risk by 27% and 22%, respectively. No differences were found between chemotherapy and ramucirumab. In patients with ECOG = 0 a greater benefit was found for chemotherapy with a reduction of the risk of death by 43% and no benefits were found for ramucirumab or everolimus. In patients with ECOG = 1 or more a significant reduction of the risk of death by 32% was reported in patients treated with ramucirumab, even if no significant difference was reported between chemotherapy and ramucirumab. This analysis reports that active and available therapies are able to prolong survival in patients with advanced gastric cancer with a different outcome based on initial patient's performance status. New trials based on a better patient stratification are awaited.

    This study assessed the diagnostic performance of transabdominal oral contrast-enhanced ultrasound (US) imaging for preoperative tumor staging of advanced gastric carcinoma by comparing it with transverse contrast-enhanced computed tomography (CT). This retrospective study included 42 patients with advanced gastric cancer who underwent laparoscopy, radical surgery, or palliative surgery because of serious complications and had a body mass index of less than 25 kg/m 2 . A cereal-based oral contrast agent was used for transabdominal oral contrast-enhanced US. Retrospective analyses were conducted using preoperative tumor staging data acquired by either transabdominal oral contrast-enhanced US or transverse contrast-enhanced CT. Both contrast-enhanced US and contrast-enhanced CT examinations were reviewed by 2 experienced radiologists independently for preoperative tumor staging according to the seventh edition of the TNM classification. The accuracy, sensitivity, and specificity were calculated by comparing the results of contrast-enhanced US and contrast-enhanced CT with pathologic findings. The overall accuracies of the imaging modalities were compared by the McNemar test. No significant difference was noted in the overall accuracy of transabdominal oral contrast-enhanced US (86% [36 of 42]) and transverse contrast-enhanced CT (83% [35 of 42] P > .999). For stage T2 to T4 gastric cancer, the accuracies of transabdominal oral contrast-enhanced US were 88%, 86%, and 98%, respectively, and those of transverse contrast-enhanced CT were 93%, 83%, and 90%. The overall accuracy of transabdominal oral contrast-enhanced US was comparable with that of transverse contrast-enhanced CT for preoperative tumor staging of advanced gastric cancer. © 2017 by the American Institute of Ultrasound in Medicine.

However, weekly paclitaxel (wPTX has become the preferable second-line chemotherapy in Japan. Histone deacetylase (HDAC inhibitors have been shown to have antiproliferative activity through cell-cycle arrest, differentiation, and apoptosis in gastric cancer cells. One HDAC inhibitor, valproic acid (VPA, also inhibits tumor growth by inducing apoptosis, and enhances the efficacy of paclitaxel in a mouse xenograft model of gastric cancer. wPTX plus VPA as a second-line chemotherapy is expected to improve survival in gastric cancer patients. A multicenter randomized Phase II study was conducted to compare the effects of wPTX plus VPA and wPTX alone. A total of 66 patients participated in this study. The primary end point of the study was overall survival, and secondary end points were progression-free survival, response rate, and assessment of peripheral neuropathy.

    To date, the optimal surgical strategy for remnant gastric cancer has not been determined. The purpose of this study was to clarify the significance of lymphadenectomy with splenectomy in remnant gastric cancer surgery. This retrospective cohort study was conducted at the Kumamoto Regional Medical Center. The primary endpoint was overall survival after surgery. We retrospectively analyzed the clinicopathologic features, surgical treatments, and long-term prognosis of remnant gastric cancer patients treated with total gastrectomy. A total of 80 patients with gastric cancer in the remnant stomach after distal gastrectomy and who underwent total gastrectomy were enrolled in the study. Splenectomy was performed in 38 patients. Lymph node metastasis in the splenic hilum was not observed in the patients with pT1/pT2 tumors, whereas nodal metastasis at the splenic hilum was detected in 30.4% of the patients with pT3/pT4 tumors. The survival rate of the patients with pT3/pT4 tumors who underwent splenectomy was significantly higher than that of the patients who did not undergo splenectomy, although there was no difference in the patients with pT1/pT2 tumors. Among the patients classified as R0, the survival rate of the patients with pT3/pT4 tumors who underwent splenectomy was significantly higher than that of the patients who did not undergo splenectomy. Lymphadenectomy with splenectomy in radical surgery is beneficial for patients with advanced (pT3/pT4) remnant gastric cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Objective: To study the effect of preoperative oral S-1 combined with regional intra-arterial chemotherapy on malignant molecule expression in locally advanced unresectable gastric cancer tissue. Methods: A total of 144 patients with locally advanced gastric cancer receiving surgical resection after neoadjuvant chemotherapy in our hospital between May 2012 and August 2015 were selected and randomly divided into experimental group who received preoperative oral S-1 combined with regional intra-arterial chemotherapy and control group who received preoperative intravenous systemic chemotherapy. The levels of serum tumor markers were determined after chemotherapy, and the expression levels of tumor suppressor genes and cell cycle-related molecules in tumor tissue were determined after surgical resection. Results: After neoadjuvant chemotherapy, the serum G-17, TK-1, CEA, CA19-9, CA12-5, CA72-4 and CK, CK-MB, ALT, AST levels of experimental group were significantly lower than those of control group; after surgical resection, the p16, p27, PTEN and TXNIP mRNA levels in tumor tissue of experimental group were significantly higher than those of control group while CyclinB2, CyclinD1, CyclinE, CDK1 and CDK2 mRNA levels were significantly lower than those of control group. Conclusions: Preoperative oral S-1 combined with regional intra-arterial chemotherapy can more effectively kill gastric cancer cells, reduce tumor load, inhibit cell cycle and promote cell apoptosis.

    Dieulafoy's lesion, also known as a caliber-persistent artery, is a shallow, small, and rare lesion that occurs along the lesser curvature of proximal stomach. It is rare for a Dieulafoy's lesion to present as a mass-like lesion that coexists with gastric cancer. To our best knowledge, we report the first case and histopathological pictures of a mass-like Dieulafoy's lesion coexisting with advanced gastric cancer in the antrum of the stomach. A 57-year-old female presented with a 6-month history of intermittent epigastric dull pain and dyspepsia. Subsequent upper gastrointestinal endoscopy revealed a friable mass that was located between the distal antrum and the pyloric ring. Biopsy revealed it to be an intestinal type adenocarcinoma. Subtotal gastrectomy was performed after neoadjuvant chemotherapy. Grossly, a large irregular plaque-like tumor lesion was noted at the anterior wall of the distal antrum and pylorus ring near the lesser curvature, measuring 5.6 × 4.8 × 1.0 cm. Histopathological examination of the resected stomach revealed that the plaque-like lesion largely consisted of numerous abnormally large-caliber and tortuous arteries in the submucosa. The increased fibrosis of the submucosa resulted in the formation of elevated plaque. The intestinal type adenocarcinoma was noted to be largely confined to the mucosa layer, with focal submucosal and muscular propria involvement. The patient was discharged one week after the subtotal gastrectomy, and she was alive and well 17 months after discharge, with no major complications. This is the first case of a mass-like Dieulafoy's lesion coexisting with advanced gastric cancer at the distal antrum area. This case highlights the possibility of life-threatening gastric bleeding after mucosal resection or biopsy that could be encountered by endoscopists.

We aimed to evaluate the potential prognostic significance of SII in patients with advanced gastric cancer who received neoadjuvant chemotherapy.Subjects and methods: The retrospective analysis included data from 107 patients with advanced gastric cancer undergoing neoadjuvant chemotherapy and 185 patients with pathology-proven gastric cancer. The optimal cutoff value of SII by receiver operating characteristic curve stratified patients into low SII (<600×109/L and high SII (SII ≥600×109/L groups. The clinical outcomes of disease-free survival (DFS and overall survival (OS were calculated by Kaplan–Meier survival curves and compared using log-rank test. Univariate and multivariate Cox proportional hazards regression models were used to analyze the prognostic value of SII.Results: The results indicated that SII had prognostic significance using the cutoff value of 600×109/L on DFS and OS in univariate and multivariate Cox regression survival analyses. Low SII was associated with prolonged DFS and OS, and the mean DFS and OS for patients with low SII were longer than for those with high SII (57.22 vs 41.56 months and 62.25 vs 45.60 months, respectively. Furthermore, we found that patients

    CT is useful in the evaluation of patients with newly diagnosed or highly suspected lung cancer. The principal role of CT is to screen those patients with metastatic disease beyond the hili from an attempt at curative thoracotomy. While CT is regarded as very sensitive, it is not considered highly specific, and thus a surgical procedure is usually recommended for definitive diagnosis of most ''positive'' CT findings. However, the authors demonstrate a few characteristic CT findings that are highly predictive of unresectable metastatic disease. These CT findings include massive mediastinal lymphadenopathy, diffuse mediastinal infiltration, pericardial involvement, vascular encasement, and advanced chest wall invasion

    Elderly patients have been often excluded from or underrepresented in the study populations of combination chemotherapy trials. The primary end point of this study was to determine the response rate and the toxicity of the weekly oxaliplatin, 5-fluorouracil and folinic acid (OXALF) regimen in elderly patients with advanced gastric cancer. The secondary objective was to measure the time to disease progression and the survival time. Chemotherapy-naive patients with advanced gastric cancer aged 70 or older were considered eligible for study entry. Patients received weekly oxaliplatin 40 mg/m2, fluorouracil 500 mg/m2 and folinic acid 250 mg/m2. All drugs were given intravenously on a day-1 schedule. A total of 42 elderly patients were enrolled. Median age was 73 years and all patients had metastatic disease. The response rate according to RECIST criteria was 45.2% (95% CIs: 30%–56%) with two complete responses, 17 partial responses, 13 stable diseases and 10 progressions, for an overall tumor rate control of 76.2% (32 patients). Toxicity was generally mild and only three patients discontinued treatment because of treatment related adverse events. The most common treatment-related grade 3/4 adverse events were fatigue (7.1%), diarrhoea (4.8%), mucositis (2.4%), neurotoxicity (2.4%) and neutropenia (4.8%). The median response duration was 5.3 months (95% CIs: 2.13 – 7.34), the median time to disease progression was 5.0 months (95% CIs: 3.75 – 6.25) and the median survival time was 9.0 months (95% CIs: 6.18 – 11.82). OXALF represents an active and well-tolerated treatment modality for elderly patients with locally advanced and metastatic gastric cancer

    Plant Technical Specifications are issued by the US NRC to ensure that safe nuclear power plant operation is maintained within the assumptions for parameters and Structures, Systems, and Components (SSCs) made in the plant safety analysis reports. The Technical Specifications are made up of Limiting Conditions for Operation (LCOs), which are the minimum set of requirements that must be met based on the assumptions of the safety analysis, Actions, which are the remedial or compensatory actions that must be taken if the LCO is not met, and Surveillance Requirements, that demonstrate that the LCO is met. The Technical Specification Actions contain Completion Times (CTs) which are the time within which remedial actions must be taken, in the event that the LCO is not met. The Improved Standard Technical Specifications (ISTS) for Westinghouse plants are contained in NUREG-1431, Revision 2. Condition A of Technical Specification 3.5.2 (ECCS- Operating) in NUREG-1431, Revision 2, allows components to be taken out of service for up to 72 hours, as long as 100% of the ECCS flow equivalent to a single Operable ECCS train exists. Condition A would allow, for example, the A train low head safety injection (LHSI) and the B train high head safety injection (HHSI) pumps to be taken out of service (for 72 hours) as long as it could be demonstrated that the remaining components could provide 100% train equivalent flow capacity. The 'cross-training' allowed by this Condition in the ISTS provides flexibility when performing routine pre-planned preventive maintenance and testing, as well as during emergent corrective maintenance and testing associated with random component inoperabilities. Without this flexibility, a unit would have to initiate a plant shutdown within 1 hour, if component(s) were inoperable in different trains. In order to implement this flexibility, the various combinations of components in opposite trains must be evaluated to determine whether 100% of the ECCS flow

    Despite the well-described benefits of laparoscopic surgery such as lower operative blood loss and enhanced postoperative recovery in gastric cancer surgery, the application of laparoscopic surgery in patients with locally advanced gastric cancer (AGC) remains elusive owing to a lack of clinical evidence. Recently, the Korean Laparoscopic Surgical Society Group launched a new multicenter randomized clinical trial (RCT) to compare laparoscopic and open D2 lymphadenectomy for patients with locally AGC. Here, we introduce the protocol of this clinical trial. This trial is an investigator-initiated, randomized, controlled, parallel group, non-inferiority trial. Gastric cancer patients diagnosed with primary tumors that have invaded into the muscle propria and not into an adjacent organ (cT2–cT4a) in preoperative studies are recruited. Another criterion for recruitment is no lymph node metastasis or limited perigastric lymph node (including lymph nodes around the left gastric artery) metastasis. A total 1,050 patients in both groups are required to statistically show non-inferiority of the laparoscopic approach with respect to the primary end-point, relapse-free survival of 3 years. Secondary outcomes include postoperative morbidity and mortality, postoperative recovery, quality of life, and overall survival. Surgeons who are validated through peer-review of their surgery videos can participate in this clinical trial. This clinical trial was designed to maintain the principles of a surgical clinical trial with internal validity for participating surgeons. Through the KLASS-02 RCT, we hope to show the efficacy of laparoscopic D2 lymphadenectomy in AGC patients compared with the open procedure.

    We studied the effects of glutamine-enriched nutritional support on intestinal mucosal barrier, matrix metalloproteinase (MMP)-2, MMP-9 and immune function during perioperative chemotherapy in patients with advanced gastric cancer. The study was conducted on 94 patients with advanced gastric cancer admitted from April 2015 to March 2016. They were randomly divided into observation and control groups, n=47. Control group was given basic nutritional support whereas glutamine-enriched nutritional support was given to patients in observation group. High-performance liquid chromatography was used to measure lactulose and mannitol ratio in urine (L/M) and ELISA was used to measure D-lactate levels before chemotherapy and in the 1st, 2nd and 3rd cycle of chemotherapy. Immunoglobulin level was detected by immune turbidimetry assay, T lymphocyte subsets were determined by flow cytometry after 3 cycles of chemotherapy, MMP-2 and MMP-9 of patients were compared between the two groups. The serious adverse reactions incidence (grade and IV) of patients were observed. To evaluate the life quality of patients, QLQ-C30 was used after 6 months. The levels of L/M and D-lactate in both groups after the first cycle of chemotherapy were significantly higher than that before chemotherapy; they began to decline after the second or third cycle, but were still significantly higher than the levels before chemotherapy (pgroups after 1st, 2nd, 3rd cycle after chemotherapy, L/M and D-lactate levels of patients in the observation group were significantly lower than in the control group (pgroup was significantly lower than control group (pgroup were significantly higher than control group (pnutritional support can effectively protect the intestinal mucosal barrier function in patients with advanced gastric cancer in their perioperative chemotherapy, improve the level of MMP-2 and MMP-9 in patients with advanced gastric cancer, enhance their immune function, reduce the incidence of adverse

    A phase I trial of first-line vorinostat, an orally bio-available histone deacetylase inhibitor, in combination with capecitabine plus cisplatin (XP) was performed to assess recommend phase II trial dose in patients with advanced gastric cancer. Five dose levels of three-weekly vorinostat-XP were tested; vorinostat was dosed at 300-400 mg once daily on Days 1-14, capecitabine at 800-1,000 mg/m(2) twice daily on Days 1-14, and cisplatin at 60-80 mg/m(2) on Day 1. To assess the pharmacodynamics of vorinostat, histone H3 acetylation was assessed in peripheral blood mononuclear cells before the study treatment and at Day 8 of cycle 1. In total, 30 patients with unresectable or metastatic gastric adenocarcinoma were included. Dose-limiting toxicities were thrombocytopenia, fatigue, stomatitis, and anorexia. The following doses were recommended for phase II trial: 400 mg of vorinostat once daily, 1,000 mg/m(2) of capecitabine twice daily, and 60 mg/m(2) of cisplatin. The most common grade 3-4 toxicities were neutropenia (47 %), anorexia (20 %), thrombocytopenia (17 %), and fatigue (13 %). In overall, response rate was 56 % (95 % confidence interval [CI]: 32-81). With a median follow-up of 14.1 months, the median progression-free survival and overall survival were 7.1 months (95 % CI: 3.8-10.3) and 18.0 months (95 % CI: 4.8-31.1), respectively. The change in H3 acetylation after treatment with vorinostat correlated significantly with the vorinostat dose (300 vs. 400 mg/day) and the baseline level of H3 acetylation before treatment. Three-weekly vorinostat-XP regimen is feasible and recommended for further development in advanced gastric cancer.

Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for advanced stage gastric cancer. Patients undergoing distal gastrectomy for advanced gastric cancer staged cT2/3/4 cN0/1/2/3a cM0 by endoscopy and computed tomography are eligible for enrollment after giving their informed consent. Patients will be randomized either to laparoscopy-assisted distal gastrectomy or open distal gastrectomy. Sample size calculation revealed that 102 patients are to be included per treatment arm. The primary endpoint is the non-compliance rate of D2 dissection; relevant secondary endpoints are three-year disease free survival, surgical and postoperative complications, hospital stay and unanimity rate of D2 dissection evaluated by reviewing the intraoperative video documentation. Oncologic safety is the major concern regarding laparoscopy-assisted distal gastrectomy for advanced gastric cancer. Therefore, the non-compliance rate of clearing the N2 area was chosen as the most important parameter for the technical feasibility of the laparoscopic procedure. Furthermore, surgical quality will be carefully reviewed, that is, three independent experts will review the video records and score with a check list. For a long-term result, disease free survival is considered a secondary endpoint for this trial. This study will offer promising evidence of the feasibility and safety of Laparoscopy-assisted distal gastrectomy for advanced gastric cancer. NCT01088204 (international), NCCCTS-09-448 (Korea).

    To evaluate the clinical significance and rarity of tamoxifen retinopathy after a long-term tamoxifen treatment for an inoperable desmoid tumor. Case report. Tamoxifen retinopathy is a condition rarely observed in clinical practice. Although tamoxifen is typically a treatment for breast cancer patients, we present a 68-year-old woman taking tamoxifen for an inoperable desmoid tumor, an equally rare condition. She presented with bilaterally deteriorating vision over the course of a year. Fundoscopic examination revealed parafoveal deposits bilaterally. Spectral domain optical coherence tomography exhibited hyperreflective deposits in all layers of the retina. She had a cumulative treatment dose of 292 g of tamoxifen, and the medication was subsequently stopped. Her vision remained stable 3 months after the cessation of tamoxifen. The development of tamoxifen retinopathy in the treatment of a desmoid tumor makes this case a rare entity, and this is the first reported case of these two concomitant conditions to our knowledge. With the use of long-term tamoxifen as a primary treatment, we recommend screening at regular intervals by an ophthalmologist as an integral part of treatment.

    Despite its decreasing incidence overall, gastric cancer is still a challenging disease. Therapy is based mainly upon surgical resection when the tumour remains localised in the stomach. Conventional chemotherapy may play a role in treating micrometastatic disease and is effective as palliative therapy for recurrent or advanced disease. However, the knowledge of molecular pathways implicated in gastric cancer pathogenesis is still in its infancy and the contribution of molecular biology to the development of new targeted therapies in gastric cancer is far behind other more common cancers such as breast, colon or lung. This review will focus first on the difference of two well defined types of gastric cancer: intestinal and diffuse. A discussion of the cell of origin of gastric cancer with some intriguing data implicating bone marrow derived cells will follow, and a comprehensive review of different genetic alterations detected in gastric cancer, underlining those that may have clinical, therapeutic or prognostic implications.

    Background Lung cancer is one of the most commonly diagnosed cancers, and is a leading cause of cancer mortality world-wide. Due to lack of early specific symptoms, the majority of patients present with advanced, inoperable disease and five-year relative survival across all stages of non-small cell lung cancer (NSCLC) is 14%. People with lung cancer also report higher levels of symptom distress than those with other forms of cancer. Several benefits for survival and patient reported outcomes ...

    Since 1994, we devised and have continued to develop a percutaneous trans esophageal gastro-tubing (PTEG) as an effective technique to drain gastrointestinal contents of critical patients suffering from gastric carcinoma. Here we report our satisfactory experience with a critical gastric cancer patient for whom we improved QOL by the application of the PTEG technique. The patient suffered from severe stenosis or obstruction of the digestive tract. This method was found to be effective enough to enable the patient to receive further medical care at home. The patient was a 36-year-old female who had far-advanced, inoperable gastric carcinoma. It was therefore decided to use the PTEG method. The PTEG method was performed using a rupture-free balloon (RFB) catheter to drain the gastrointestinal contents. A reservoir-port for IVH use was embedded to control the patient's nutrition. A morphine hydrochloride suppository was then given for the pain. PTEG was found to be effective, safe and simple; moreover, it is a less-invasive, intestine-maintaining method, which enabled the patient to continue receiving further medical treatment at home.

    Gastrointestinal stromal tumours (GIST) are rare neoplasms originating from connective tissue in the digestive tract with an incidence of less than 1% and account for most non-epithelial primitive digestive tumours. Metastasis diagnosed at the time of disease discovery confirms GIST malignancy. Kit protein, a trans-membrane tyrosine kinase receptor of staminal cells, is characteristically expressed by GIST. Most GIST have a mutation in the kit proto-oncogene. Resistance to conventional chemotherapy is commonly shown by malignant GIST. Most patients with advanced malignant GIST achieve clinical benefit with imatinib mesilate, an orally administered selective inhibitor of the tyrosine kinase receptor. We treated a 43-year-old male patient suffering from a gastric GIST diagnosed during a surgical emergency operation for peritonitis caused by gastric perforation. At the time of the first operation the patient had lost 10 kg body weight over the previous months and was seriously cachectic. During the emergency operation the perforation was sutured. The biopsy results showed the presence of CD1 17 (c-kit) and CD34 markers. A total body CT scan documented the substantial size of the gastric wall lesion, an increased volume of abdominal lymph nodes and compression of the splenic vein with alternative collateral circulation. The liver presented no less than 5 large metastases distributed in both the left and right lobes. There was also a pulmonary metastasis. Because of frequent spontaneous bleeding and starvation the patient was seriously anaemic. Considering the action mechanism of imatinib and the extent of the lesion we decided to perform a total gastrectomy procedure. At the time of the operation the stomach seemed to have a modified volume and shape: it appeared to be divided into two sacs, the larger and deeper of which was the original gastric cavity, while the superficial, smaller one seemed to be a protrusion of the organ. The stomach was indistinguishable from

    To present the initial experience of percutaneous radiofrequency ablation (RFA) of inoperable primary lung cancer, and to assess the technical feasibility and potential complications. Twenty patients with inoperable lung cancer underwent percutaneous RFA. Nineteen of 20 patients had stage III or IV non-small cell lung cancer, and the remaining one had stage I lung cancer with pulmonary dysfunction. The mean tumor size was 4.6 ± 0.4 cm (range, 1.8-8.4 cm). RFA was performed with a single (n = 18) or cluster (n = 2) cool-tip RF electrode and a generator under CT guidance using local anesthesia and conscious sedation. Twenty tumors were treated in 28 sessions. Patients were assessed by contrast-enhanced CT in all cases at 1 week, 1 month, and 3 months. Eleven patients received chemotherapy (n = 10) or radiotherapy (n = 1) after RFA. RFA was technically successful and well tolerated in all patients. Complete necrosis was attained in 7 lesions (35%), near complete (90-99%) necrosis in 10 lesions (50%), and partial (50-89%) necrosis in 3 lesions (15%). During the mean follow up of 202 days (21 to 481 days), tumor size was decreased in 13 patients, unchanged in 3, and increased in 4. In the latter four, additional RFA was performed. One patient underwent surgery three months after RFA and the histopathologic findings showed a large cavity with thin fibrotic wall suggestive of complete necrosis. During or after the procedure, pneumothorax (n = 10), moderate pain (n = 4), blood tinged sputum (n = 2), and pneumonia (n = 2) were developed. Chest tube drainage was required in only 1 patient due to severe pneumothorax. Other patients were managed conservatively. Seven patients died at 61 to 398 days (mean, 230 days) after RFA. The remaining 13 patients were alive 21 to 481 days (mean, 187 days) after RFA. RFA appears to be a technically feasible and relatively safe procedure for the cytoreductive treatment of inoperable, non-small cell lung cancer and warrants further

    To investigate the activity and toxicity of high dose (HD) infusional 5-FU in comparison to EAP regimen as first-line chemotherapy in patients with advanced gastric cancer. Histologically confirmed measurable advanced gastric cancer, age EAP arm: doxorubicin (40 mg/m(2)), etoposide (360 mg/m(2)), and cisplatin (80 mg/m(2)) every 28 d; HD 5-FU arm: 5-FU 2.6 g/m(2) 24 h infusion, biweekly. Sixty patients were randomized. Patient characteristics (arms EAP/HD 5-FU): Median age 57/55 yr, median PS 1/1, LAD (patients) 3/8, M1 (patients) 27/22. Median number of cycles (range): EAP arm 4 (2-8), HD 5-FU arm 2 (1-8). Worst toxicity per cycle (grade 3 and 4 in%): Neutropenia 20/3, thrombocytopenia 9/0, anemia 9/13, diarrhea 3/10, nausea 17/7, vomiting 10/0 for EAP and HD 5-FU arms, respectively. All patients were eligible for response in both arms. Confirmed response rate (95%CI): EAP arm 34% [16-50%]/HD 5-FU arm 10% (0-21%), no change: 46/40%, progression of disease: 20/50, respectively. Overall survival (range): EAP arm A 7 mo [3-27], HD 5-FU arm 6 mo (4-25). Infusional HD 5-FU showed a low incidence of severe toxicity. But given the low efficacy of 5-FU in the dosage we applied in the study, it cannot be recommended as a single treatment for further studies. Assessment of higher dose intensity and/or dose density of 5-FU, with introduction of other active drugs in combination, could be an option for further studies.

    Despite all benefit provided by established therapies prognosis of gastric cancer remains poor. Targeted inhibition of platelet derived growth factor receptor (PDGFR) by imatinib may influence tumor growth and amplify chemotherapeutic effects. This phase I study evaluated dose limiting toxicity (DLT) of imatinib combinated with chemotherapy according to a 3-patient cohort dose-escalating design. Thirty-five patients received cisplatin (60 mg/m 2 d1 q 3w)/ capecitabine (1250 mg/m 2 bid d1-14 q 21) or cisplatin (50 mg/m 2 d1 q 2w)/ 5-fluoruracil (2 g/m 2 d1, q 1w). Imatinib was started d - 4 with dose escalation from 300 to 700 mg QD in 100 mg steps. At imatinib dose level 1 (300mg) one DLT was observed, three more patients were enrolled without further DLT. At dose level 5 (700 mg) two gastric perforations occurred, so 600 mg imatinib emerged as the maximum tolerated dose. Major grade 3/4 toxicities were nausea (6%), anemia (6%) and fatigue (3%). Response evaluation revealed partial response in 27% and stable disease in 43% of the assessable patients. Combination of imatinib and chemotherapy is well tolerated. Response rates were not superior to those of standard therapy. Further investigations of a larger group of patients are required to confirm the amplification of chemotherapy effects by imatinib.

    Gastric pseudolymphoma is an uncommon benign lesion which poses a difficult problem in diagnosis and management. Lymphoid hyperplasia of the stomach, however, may occasionally precede true gastric lymphoma. Endoscopic, radiologic and pathological findings are not generally helpful in establishing the diagnosis preoperatively. Benign gastric lymphoid hyperplasia could be mistaken radiologically for ulcerated gastric carcinoma and pathologically for malignant lymphoma. Recognition of this condition is important to prevent unnecessary treatment by surgery or radiotherapy. About 140 case reports have been published to date. This paper describes the cases of two further patients. (orig.) [de

    The aim of this study was to determine the medical and technical feasibility of intensity-modulated radiotherapy (IMRT) in high-risk nonmetastatic gastric cancer stage II and III after primary gastrectomy and D2 lymphadenectomy. A prospective nonrandomized phase II trial was performed on 25 consecutive patients with gastric cancer with high risk (T3-4, N1-3, G2-3, R0-1). The dose delivered was 45 Gy (1.80 Gy per fraction) in IMRT technique. Concurrent 5-fluorouracil-based chemotherapy at 225 mg/m(2) was administered as a continuous intravenous infusion. Primary endpoints were acute gastrointestinal toxicity (CTC 4.0) and technical feasibility of IMRT in regard to dose planning and radiation delivery. Early acute events were defined as clinical and chemical adverse effects of IMRT and concurrent chemotherapy during treatment. By definition, 90 days after the end of IMRT has been evaluated as acute-phase toxicity. No patient had grade 4 or higher acute adverse events. Clinical grade 3 toxicity occurred in two patients (8%) with diarrhea and in one case (4%) with nausea. Hematological changes with grade 3 occurred in three cases (12%) with hemoglobin decrease, in five cases (25%) as leukopenia, and in one case (4%) with thrombocytopenia. The mean dose for liver was 16 Gy and the percentage volume exceeding 30 Gy (V30) was 21%. Mean dose for right and left kidney was 9 and 13 Gy, respectively, and V20 was 9% and 13%, respectively. Heart received a median dose of 15 Gy and V40 was 17%. The mean dose to the bowel was 11 Gy and V40 was 6%. Spinal cord had at maximum 33 Gy in median. Specifics of dose distribution, including the coverage, for the target region were as follows: minimum was 33 Gy, maximum 48.6 Gy, and mean dose 44.6 Gy. The prescribed dose (45 Gy) covered 99% and 95% of planning target volume (OTV) in 66% and 92% of cases, respectively. Median PTV was 15.77 ml (range, 805-3,604 ml). The data support the practical feasibility of IMRT in adjuvant treatment in

    acid (LNA)/ 2' O-methyl RNA (2'OMe) probe using standard phosphoramidite chemistry and FISH hybridization was then successfully performed both on adhered and suspended bacteria at 37°C. In this work we simplified, shortened and adapted FISH to work at gastric pH values, meaning that the hybridization...... step now takes only 30 minutes and, in addition to the buffer, uses only urea and probe at non-toxic concentrations. Importantly, the sensitivity and specificity of the FISH method was maintained in the range of conditions tested, even at low stringency conditions (e.g., low pH). In conclusion......In recent years, there have been several attempts to improve the diagnosis of infection caused by Helicobacter pylori. Fluorescence in situ hybridization (FISH) is a commonly used technique to detect H. pylori infection but it requires biopsies from the stomach. Thus, the development of an in vivo...

    The surgical treatment of gastric cancer has better long-term survival rates when performed in patients with early gastric cancer. Worse results are obtained in treatment of advanced gastric cancer. Most patients in west centers are treated in advanced stages. A great number of them go through a surgical treatment unable by itself to cure them. the frequent local recurrence caused by failure of the surgical treatment has been keeping poor survival rates in patients with advanced gastric cancer for decades. The desire of improving survival is the reason of the use of adjuvant therapies. This paper achieved the retrospective study of the influence of preoperative radiation therapy (2000 cGy) in long-term survival rates (120 months) of patients with advanced gastric cancer on stages IIIa, IIIb and IV. The possible injuries caused in the liver and kidney were observed also as well as first group was treated by surgical and radiation therapies and the second received surgical treatment only. There was no statistical difference between the two groups when sex, age, race, occurrence of other diseases, nutritional assessment, TNM stage, occurrence of obstruction or bleeding caused by tumor, surgical procedure and hepatic and renal function were considered. Survival rates and changes on hepatic and renal function were statistically compared. The results showed a statistic improvement on the long-term survival rates of stage IIIa patients treated by preoperative radiation therapy. No statistic difference was observed on hepatic or renal function between the groups. No adverse influence of radiation therapy method was detected by the used parameters. There was no statistical difference between the two groups when immediate surgical complications were considered. (author) 112 refs., 34 tabs.

    Percutaneous destruction of cancer cells using a radiofrequency energy source has become an accepted part of the modern armamentarium for managing malignancies. Radiofrequency ablation (RFA) is a relatively novel procedure for treating recurrent and metastatic tumors. It is used for debulking tumors and as adjuvant therapy for palliative care apart from its role as a pain management tool. Its use in the third world countries is limited by various factors such as cost and expertise. In the remotest parts of India, where economic development has been slow, abject poverty with poor health care facilities advanced malignancies present a challenge to health care providers. We undertook this study to assess the safety of the percutaneous RFA tumor ablation as a therapeutic or palliative measure in patients where surgery was not possible. We observed that RFA may be an effective, alternative therapeutic modality for some inoperable tumors where other therapeutic modalities cannot be considered. Palliative and therapeutic image-guided RFAs of tumors may be the only treatment option in patients who are inoperable for a variety of reasons. To assess the safety and complications of RFA in such a patient population is important before embarking upon any interventions given their physically, mentally, and socially compromised status in a country such as India. To assess the safety of percutaneous image-guided radiofrequency tumor ablation and to note the various immediate and early complications of the intervention. This was a prospective, observational study conducted in Tata Main Hospital, Jamshedpur, Jharkhand, India. After approval by the Hospital Approval Committee all patients who consented for percutaneous RFA of their tumor admitted in the hospital were included after taking fully informed consent from patient/close relative keeping the following criteria in view. Patients who were likely to derive a direct benefit in the survival or as a palliative measure for relief

    Full Text Available Objective: Fluorouracil (5-FU is widely used in the treatment of gastric cancer. Methylenetetrahydrofolate reductase (MTHFR and thymidylate synthetase (TS are important targets of many antimetabolites, including 5-FU. The relationship between polymorphism in the MTHFR (C677T, A1298C and TS (5`-TUR, 3`-UTR genotypes and sensitivity of gastric cancer to 5-FU-based chemotherapy is investigated in the present study. Methods: 173 patients with advanced gastric cancer were analyzed. All patients were treated with 5-FU-based chemotherapy (FOLFOX, FP and DCF regimen. DNA from peripheral blood leukocytes was obtained before the treatment. All genotypes were detected by PCR-RFLP. 12 germline polymorphisms within 2 genes were analyzed. The genotypes of MTHFR C677T, A1298C and TS 3`-TUR were analyzed in 173 patients while TS 5`-TUR in 135 patients. Results: The overall response rate (RR was 35.8%. The RR of the DCF regimen group was significantly higher than that of the FP and FOLFOX regimen groups (55.8% vs. 27.1%, 31.1%; P=0.006. The RR of the MTHFR C677T T/T genotype was significantly higher than that of the C/ C and C/T genotypes (73.3% vs. 28.0%; P=0.000. In MTHFR A1298C, a higher RR was observed in A/A genotype compared with the C/C and A/C genotypes (41.8% vs. 21.6%, P=0.011. The RR of -6/-6 bp and -6/+6 bp genotypes in TS 3`UTR was significantly higher than that of +6/+6 bp genotype (40.3% vs. 17.6%, P=0.014. There was no difference in RR according to TS 5`UTR polymorphism (2R/2R and 2R/3R: 41.7% vs. 3R/3R: 36.8%, P=0.487. The RR of MTHFR C677T T/T genotypes in FOLFOX or FP regimens was significantly higher than that of C/C and C/T genotypes (P=0.008, P=0.000 while no difference in DCF regimen. The RR of DCF regimen wassignificantly higher than that of FOLFOX and FP regimens in C/T and C/C genotypes (P=0.000. The MTHFR C677T T/T genotypes had a significantly higher incidence of grade 3/4 emesis (66.7% and stomatitis (30.0% than patients with C/T or

    Full Text Available BACKGROUND: Many reports have shown inconsistent results on the relationship between single nucleotide polymorphisms (SNPs of X-ray repair cross complementing protein (XRCC1 gene and platinum-based chemotherapeutic efficacy. This meta-analysis aimed to summarize published data about the association between two SNPs of XRCC1 (Arg194Trp and Arg399Gln and treatment outcomes of patients with advanced gastric cancer. METHODOLOGY/PRINCIPAL FINDINGS: We retrieved the relevant articles from MEDLINE, Web of Knowledge, and the China National Knowledge Infrastructure (CNKI databases. Studies were selected according to specific inclusion and exclusion criteria. Study quality was assessed according to the guidelines outlined by Hayden, et al. and PRISMA guidelines. We estimated the odds ratio (OR for response rate versus no response after platinum-based chemotherapy. Progression-free survival (PFS and overall survival (OS were evaluated by pooled Cox proportional hazard ratios (HRs and 95% confidence intervals (CIs. We found that none of the XRCC1 Arg194Trp and Arg399Gln polymorphisms was significantly associated with tumor response. Stratified analysis by ethnicity or sensitivity analysis also showed that XRCC1 SNPs were not related with chemotherapy response. Patients with minor variant A allele were likely to have poorer 2-year survival rate than those with G/G genotype. However, in the group of 5-year follow up, there was no significant association between the A allele and OS yet. CONCLUSIONS/SIGNIFICANCE: There is no evidence to support the use of XRCC1 Arg194Trp and Arg399Gln polymorphisms as prognostic predictors of TR and PFS in gastric patients treated with platinum-based chemotherapy. The relationship between minor variant A allele and OS requires further verification.

    Definitive chemoradiation (dCRT) is considered curative intent treatment for patients with inoperable or irresectable esophageal cancer. Acute toxicity data focussing on dCRT are lacking. A retrospective analysis of patients treated with dCRT consisting of 6 cycles of paclitaxel 50 mg/m2 and carboplatin AUC2 concomitant with radiotherapy (50.4 Gy/1.8Gy) from 2006 through 2011 at a single tertiary center was performed. Toxicity, hospital admissions and survival were analysed. 127 patients were treated with definitive chemoradiation. 33 patients were medically inoperable, 94 patients were irresectable, Despite of a significantly smaller tumor length in inoperable patients grade ≥3 toxicity was significantly recorded more often in the inoperable patients (44%) than in irresectable patients (20%) (p < 0.05) Hospital admission occurred more often in the inoperable patients (39%) than in the irresectable patients (22%) (p < 0.05) Median number of cycles of chemotherapy was five for inoperable patients (p = 0.01), while six cycles could be administered to patients with irresectable disease. Recurrence and survival were not significantly different. The odds ratio for developing toxicity ≥ grade 3 was 2.6 (95% CI 1.0-6.4 p < 0.05) for being an inoperable patient and 1.2 (95% CI 1.0-1.4 p = 0.02) per 10 extra micromol/l creatinine. Our data show that acute toxicity of definitive chemoradiation is worse in patients with medically inoperable esophageal carcinoma compared to patients with irresectable esophageal cancer and mainly occurs in the 5th cycle of treatment. Improvement of supportive care should be undertaken in this more fragile group

    This randomised phase III study was conducted to investigate the efficacy of extended nodal irradiation (ENI) and/or erlotinib in inoperable oesophageal squamous cell cancer (ESCC). Patients with histologically confirmed locally advanced ESCC or medically inoperable disease were randomly assigned (ratio 1:1:1:1) to one of four treatment groups: group A, radiotherapy adoption of ENI with two cycles of concurrent TP chemotherapy (paclitaxel 135 mg/m 2  day 1 and cisplatin 20 mg/m 2 days 1-3, every 4 weeks) plus erlotinib (150 mg per day during chemoradiotherapy); group B, radiotherapy adoption of ENI with two cycles of concurrent TP; group C, radiotherapy adoption of conventional field irradiation (CFI) with two cycles of concurrent TP plus erlotinib; group D, radiotherapy adoption of CFI with two cycles of concurrent TP. A total of 352 patients (88 assigned to each treatment group) were enrolled. The 2-year overall survival rates of group A, B, C and D were 57.8%, 49.9%, 44.9% and 38.7%, respectively (P = 0.015). Group A significantly improved 2-year overall survival compared with group D. The ENI significantly improved overall survival in patients with inoperable ESCC (P = 0.014). The addition of erlotinib significantly decreased loco-regional recurrence (P = 0.042). Aside from rash and radiation oesophagitis, the incidence of grade 3 or greater toxicities did not differ among 4 groups. Chemoradiotherapy with ENI and erlotinib might represent a substantial improvement on the standard of care for inoperable ESCC. ENI alone should be adopted in concurrent chemoradiotherapy for ESCC patients. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available In recent years, there have been several attempts to improve the diagnosis of infection caused by Helicobacter pylori. Fluorescence in situ hybridization (FISH is a commonly used technique to detect H. pylori infection but it requires biopsies from the stomach. Thus, the development of an in vivo FISH-based method (FIVH that directly detects and allows the visualization of the bacterium within the human body would significantly reduce the time of analysis, allowing the diagnosis to be performed during endoscopy. In a previous study we designed and synthesized a phosphorothioate locked nucleic acid (LNA/ 2' O-methyl RNA (2'OMe probe using standard phosphoramidite chemistry and FISH hybridization was then successfully performed both on adhered and suspended bacteria at 37°C. In this work we simplified, shortened and adapted FISH to work at gastric pH values, meaning that the hybridization step now takes only 30 minutes and, in addition to the buffer, uses only urea and probe at non-toxic concentrations. Importantly, the sensitivity and specificity of the FISH method was maintained in the range of conditions tested, even at low stringency conditions (e.g., low pH. In conclusion, this methodology is a promising approach that might be used in vivo in the future in combination with a confocal laser endomicroscope for H. pylori visualization.

    Purpose: The current study was conducted to investigate the incidence and risk factors for medical complications associated with low dose rate brachytherapy in patients with medically inoperable Stage I endometrial cancer treated with irradiation alone. Methods and Materials: From 1965 through 1991 at Mallinckrodt Institute of Radiology, 150 implants were performed on 96 patients who were deemed medically unfit for hysterectomy because of advanced age, obesity, and various medical problems. The records of these patients were examined retrospectively to determine the incidence of medical complications that occurred in the first 30 days following the initiation of brachytherapy. The association of risk factors that precluded major surgery and the occurrence of brachytherapy-related complications was examined by logistic regression. Results: Of these 96 patients, 40 patients were older than 75 years, and 31 patients were deemed morbidly obese. Medical problems included hypertension in 45 patients, and diabetes in 37; there was a history of congestive heart failure in 23, stroke in 11, myocardial infarction in 10, and thromboembolism in 8. There were concurrent malignancies in five patients. Implants were performed using intrauterine Simon-Heyman capsules, tandems, and vaginal ovoids in all patients. General anesthesia was used for 98 implants, spinal anesthesia for 26, local anesthesia for 25, and epidural anesthesia for 1. The duration of anesthesia ranged from 30 to 120 min (median, 60 min). The duration of radioisotope application ranged from 11 to 96 h (median, 46 h). Preventive measures included low dose subcutaneous heparin in 55 patients (since 1978), and intermittent pneumatic compression boots in 29 (since 1985). Four patients developed life-threatening complications including myocardial infarction (two patients), congestive heart failure (one patient), and pulmonary embolism (one patient). Two of these four patients died; one with a myocardial infarction and

    Gastric neuroendocrine tumours (NETs) are increasingly recognised, and management decisions may be difficult due to an incomplete understanding of aetiology, natural history and optimum therapy. This article presents a current understanding based on recent advances in epidemiology, classification, molecular profiling, and treatment. Relevant medical literature was identified from searches of PubMed and references cited in appropriate articles identified. Selection of articles was based on peer review, journal and relevance. Gastric NETs may be divided into three clinical prognostic groups: type I is associated with autoimmune atrophic gastritis and hypergastrinaemia, type II is associated with Zollinger-Ellison syndrome, and type III lesions are gastrin-independent, have the greatest metastatic potential and poorest prognosis. There has been an increased frequency of gastric NETs reported. Management approaches have evolved in parallel with advances in endoscopic staging and surgery, as well as improved understanding of the biology and natural history of NETs. Gastric NETs present a spectrum of activity from indolent tumours to metastatic malignancy. Treatment decisions for patients must be individualised and are best managed by a multidisciplinary team approach. The current evidence base is limited to small series and efforts to treat patients within clinical networks of expertise are warranted. Copyright © 2012 S. Karger AG, Basel.

    Deletion of the HSP110 T 17 mononucleotide repeat has recently been identified as a prognostic marker that is correlated with wild-type HSP110 (HSP110wt) expression in microsatellite instability-high (MSI-H) colorectal cancers. The aim of this study was to assess the correlation between deletion of the HSP110 T 17 repeat and expression of HSP110wt using DNA testing and immunohistochemistry and to determine the prognostic implications of HSP110 T 17 deletion in MSI-H advanced gastric cancers (GCs). The status of HSP110wt expression was evaluated by immunohistochemistry using an HSP110wt-specific antibody in 142 MSI-H advanced GCs. The size of the HSP110 T 17 repeat deletion was analyzed in 96 MSI-H advanced GCs; deletions were divided into small (0-2base pairs) and large deletions (3-5base pairs). Low and high expressions of HSP110wt were detected in 38 (26.8%) and 104 (73.2%) of the 142 cases, respectively. The HSP110 T 17 deletion was observed in 45 (46.9%) of the 96 MSI-H GC samples. Tumors with high expression of HSP110wt showed a tendency to have small or no deletion of HSP110 T 17 . In Kaplan-Meier survival analysis, tumors with a large HSP110 T 17 deletion were associated with favorable overall survival and disease-free survival compared with those with small/no deletion of HSP110 T 17 . However, HSP110 T 17 deletion size was not an independent prognostic factor in multivariate analysis. In summary, deletion of the HSP110 T 17 repeat was frequently observed in MSI-H GCs, and HSP110 T 17 deletion size was inversely correlated with HSP110wt expression status. Large HSP110 T 17 was not a prognostic indicator in MSI-H GCs. Copyright © 2017 Elsevier Inc. All rights reserved.

    Little evidence is available on the management and cost of treating patients with advanced or metastatic gastric cancer (GC). This study evaluates patient characteristics, treatment patterns, and resource utilization for these patients in Mexico. Data were collected from three centers of investigation (tertiary level). Patients were ≥18 years of age, diagnosed between 1 January 2009 and 1 January 2015, had advanced or metastatic GC, received first-line fluoropyrimidine/platinum, and had ≥3 months follow-up after discontinuing first-line treatment. Data were summarized using descriptive statistics. The study sample totaled 180. Patients' mean age was 57.2 years (±12.4) and 57.0% were male; 151 (83.9%) patients received second-line chemotherapy. A total of 16 and 19 regimens were identified in first- and second-line therapy. Of the sample, 51 (28.3%) received third-line therapy, and <10% received more than three lines of active chemotherapy. Supportive care received in first- and second-line chemotherapy, included pain interventions (12.2 and 7.9%), nutritional support (3.3 and 1.3%), radiotherapy (6.1 and 16.6%), and transfusions (13.3 and 10.6%), respectively. Using Mexican Institute of Social Security (IMSS) tariffs, the average total cost per patient-month in first- and second-line therapy was US$1230 [95% confidence interval (CI) 1034-1425] and US$1192 (95% CI 913-1471), respectively. Administration and acquisition of chemotherapy comprised the majority of costs. This study shows considerable variation in first- and second-line chemotherapy regimens of patients with advanced or metastatic GC. Understanding GC treatment patterns in Mexico will help address unmet needs.

    Lymph node metastases are an independent prognosis factor in gastric carcinoma (GC) patients. Radical lymphadenectomy can improve survival but it can also increase surgical morbidity. As a principle, sentinel node (SN) navigation surgery can avoid unnecessary lymphadenectomy without compromising prognosis. In this pilot study, 24 patients with untreated GC were initially screened for SN navigation surgery, of which 12 were eligible. Five patients had T2 tumors, 5 had T3 tumors and 2 had T1 tumors. In 33% of cases, tumor diameter was greater than 5.0 cm. Three hundred and eighty-seven lymph nodes were excised with a median of 32.3 per patient. The SN navigation surgery was feasible in all patients, with a median of 4.5 SNs per patient. The detection success rate was 100%. All the SNs were located in N1 and N2 nodal level. In 70.9% of cases, the SNs were located at lymphatic chains 6 and 7. The SN sensitivity for nodal staging was 91.6%, with 8.3% of false negative. In 4 patients who were initially staged as N0, the SNs were submitted to multisection analyses and immunohistochemistry, confirming the N0 stage, without micrometastases. In one case initially staged as negative for nodal metastases based on SN analyses, metastases in lymph nodes other than SN were found, resulting in a 20% skip metastases incidence. This surgery is a reproducible procedure with 100% detection rate of SN. Tumor size, GC location and obesity were factors that imposed some limitations regarding SN identification. Results from nodal multisection histology and immunohistochemistry analysis did not change initial nodal staging. (author)

    2007-06-01

    Full Text Available Abstract Background The RECIST guidelines are commonly used in phase II and III clinical trials. The correct definition of response can be controversial in some situations, as in the case we describe. Case presentation A 43 year-old man with advanced gastric cancer was enrolled in a phase II trial where he was treated with pemetrexed 500 mg/m2 plus oxaliplatin 120 mg/m2 every 3 weeks. At baseline, the target lesions were lymph-nodes, and the non-target lesions were small pulmonary nodules. At first re-evaluation, the target lesions showed partial response and the non-target lesions showed complete response, but new diffuse osteoblastic lesions appeared. The investigator decided to continue treatment until the second re-evaluation. CT scan confirmed the response of the target and non-target lesions, while the osteoblastic lesions did not change. Conclusion The appearance of osteoblastic lesions after an active antitumor treatment, a phenomenon known as flare, can complicate the definition of the best overall response using RECIST criteria. This possibility should be considered by oncologists involved in clinical trials.

    A few studies suggest that non-invasive ventilation (1) and gastric tube (G-tube) may have a positive impact on survival but the effect on functional decline is unclear. Confounding by indication may have produced biased estimates of the benefit seen in some of these retrospective studies. The objective of this study was to evaluate the effects of G-tube and NIV on survival and functional decline using advanced statistical models that adjust for confounding by indications. A database of 331 subjects enrolled in previous clinical trials in ALS was available for analysis. Marginal structural models (MSM) were used to compare the mortality hazards and ALSFRS-R slopes between treatment and non-treatment groups, after adjusting for confounding by indication. Results showed that the placement of a G-tube was associated with an additional 1.42 units/month decline in the ALSFRS-R slope (p NIV had no significant effect on ALSFRS-R decline or mortality. In conclusion, marginal structural models can be used to adjust for confounding by indication in retrospective ALS studies. G-tube placement could be followed by a faster rate of functional decline and increased mortality. Our results may suffer from some of the limitations of retrospective analyses.

    AIM: To evaluate the feasibility and safety of fluoroscopic-guided covered metallic stent placements in providing palliative care for patients with inoperable malignant gastric outlet obstruction. MATERIALS AND METHODS: Under fluoroscopic guidance, placement of self-expandable, covered stents was attempted in 20 patients with inoperable or recurrent gastric cancer (age range 36-79 years). All patients had inoperable gastric outlet obstruction, 13 with native anatomy and seven with post-operative anatomy (gastrointestinal anastomotic sites). All patients had intolerance to oral alimentation and/or vomiting after ingestion. Success was defined both technically and clinically. RESULTS: The placement of the stent was technically successful in 18 patients and failed in two patients (technical success: 90%). The cause of the technical failures was an inability to negotiate the guide wire through the obstruction sites in spite of the use of both fluoroscopic and endoscopic guidance. After stent placement, 15 patients were able to ingest at least liquids and had a markedly decreased incidence of vomiting (clinical success: 75%). During the mean follow-up of 6 weeks, there have been no stent reocclusion and no life-threatening complications except migration of two stents in one patient. CONCLUSION: Fluoroscopically guided covered metallic stent placement appears to be valuable for the palliative treatment of malignant obstruction of gastric outlet and post-operative gastrointestinal anastomoses.

    The prevalence of depression has been reported to be higher in cancer patients, especially those of advanced stage, compared to normal controls. However, depression is often under-recognized in clinical oncology settings. And this psychological problem is not routinely assessed even in patients with inoperable metastatic cancer who often have psychological disorders. Psychological distress including depression, is affected by physical, psychosocial, and clinical factors. In order to detect psychiatric problems at the early stage, we assessed the mental conditions of 47 inpatients with metastatic gastric and colorectal cancerusing the Japanese version of Zung's Self Rating Depression Scale(SDS)and analyzed the relationships between these factors and SDS scores. While SDS scores of our patients did not differ according to their gender, age, performance status (PS), ortypes of patients' character, they were significantly higher in Group B(cancer patients with palliative care alone), compared to Group A(those receiving chemotherapy)(pterminal stage, their scores were significantly increased, respectively(pterminally ill patients without any indication of chemotherapy.

  4. International trade inoperability input-output model (IT-IIM): theory and application.

    2009-01-01

    The inoperability input-output model (IIM) has been used for analyzing disruptions due to man-made or natural disasters that can adversely affect the operation of economic systems or critical infrastructures. Taking economic perturbation for each sector as inputs, the IIM provides the degree of economic production impacts on all industry sectors as the outputs for the model. The current version of the IIM does not provide a separate analysis for the international trade component of the inoperability. If an important port of entry (e.g., Port of Los Angeles) is disrupted, then international trade inoperability becomes a highly relevant subject for analysis. To complement the current IIM, this article develops the International Trade-IIM (IT-IIM). The IT-IIM investigates the resulting international trade inoperability for all industry sectors resulting from disruptions to a major port of entry. Similar to traditional IIM analysis, the inoperability metrics that the IT-IIM provides can be used to prioritize economic sectors based on the losses they could potentially incur. The IT-IIM is used to analyze two types of direct perturbations: (1) the reduced capacity of ports of entry, including harbors and airports (e.g., a shutdown of any port of entry); and (2) restrictions on commercial goods that foreign countries trade with the base nation (e.g., embargo).

    Economists have long conceptualized and modeled the inherent interdependent relationships among different sectors of the economy. This concept paved the way for input-output modeling, a methodology that accounts for sector interdependencies governing the magnitude and extent of ripple effects due to changes in the economic structure of a region or nation. Recent extensions to input-output modeling have enhanced the model's capabilities to account for the impact of an economic perturbation; two such examples are the inoperability input-output model((1,2)) and the dynamic inoperability input-output model (DIIM).((3)) These models introduced sector inoperability, or the inability to satisfy as-planned production levels, into input-output modeling. While these models provide insights for understanding the impacts of inoperability, there are several aspects of the current formulation that do not account for complexities associated with certain disasters, such as a pandemic. This article proposes further enhancements to the DIIM to account for economic productivity losses resulting primarily from workforce disruptions. A pandemic is a unique disaster because the majority of its direct impacts are workforce related. The article develops a modeling framework to account for workforce inoperability and recovery factors. The proposed workforce-explicit enhancements to the DIIM are demonstrated in a case study to simulate a pandemic scenario in the Commonwealth of Virginia.

    Purpose: To determine the activity and toxicity of paclitaxel and concurrent radiation for gastric cancer. Methods and Materials: Twenty-seven patients were studied. Twenty-five had proximal gastric cancers, two had distal cancers. Eight had esophageal extension, 6 had celiac adenopathy, and 7 had retroperitoneal adenopathy. Patients received paclitaxel, 50 mg/m 2 by 3-hour intravenous (IV) infusion, weekly, on days 1, 8, 15, 22, and 29. Radiation was administered concurrently to a total dose of 45.0 Gy, in 1.80 Gy fractions, for 25 treatments. Patients who were medically or surgically inoperable received a sixth week of paclitaxel with a radiation boost to 50.4 Gy. Results: Esophagitis and gastritis were the most important toxicities, Grade 3 in four patients (15%), and Grade 4 in three patients (11%). Five patients (19%) had Grade 3 nausea. The overall response rate was 56%, including three patients (11%) with a complete response. The 2-year progression-free and overall survival rates were 29% and 31%, respectively. Conclusion: Concurrent paclitaxel and radiation demonstrates substantial local-regional activity in gastric cancer. Future investigations combining paclitaxel and radiation with other local-regional and systemic treatments are warranted

    Gastric cancer can be classified into two categories based on the absence or presence of symptoms at diagnosis. Differences in clinicopathological features and prognoses between asymptomatic gastric cancer (ACG) and symptomatic gastric cancer (SGC) can be used to inform diagnosis strategies and ultimately improve survival rates. All cases of gastric cancer (239 AGC, 323 SGC) diagnosed in our hospital between 1997 and 1999 were used in this study. ACG patients showed significantly higher frequency of males, cases of early cancer, cases found by a mass screening program, cases treated by endoscopic resection, cases treated by curative operation, cases of type 0 macroscopic finding, cases of histologically-differentiated type, and stage I cases. By contrast, SGC patients showed significantly higher numbers of cases treated by chemotherapy alone or best support care, cases of type 2, 3, and 4 macroscopic findings, cases occupying the whole stomach, and cases of stage II, III, IV. Statistically significant differences were also found for the 5-year survival rate (83.3% in AGC, 41.2% in SGC), the incidence of early cancer (90.1% in AGC, 83.7% in SGC), and for advanced cancer (38.7% in AGC, 22.7% in SGC). The higher incidence of advanced cases in SGC than in AGC (40.0% vs. 13.0%), coupled with the low 5-year survival rate of advanced SGC (22.7%), provides strong evidence of the importance of diagnosing gastric cancer during its asymptomatic period.

    Gastric emptying (GE) of nutriments is a major function of the stomach. GE disorders are observed after gastric surgery and with various diseases, either of a strictly gastroenterologic kind or interesting other specialities (especially diabetes mellitus). Scintigraphy, which has allowed a better knowledge of GE physiological and pathological mechanisms, has now become the reference method for studying the emptying of solids and liquids. In a near future, it could well have two major applications: a diagnostic approach of functional digestive disorders and an assessment of the various effects of pharmacological drugs with digestive affinity [fr

    Radio-chemotherapy Gastro-intestinal inter-group study have demonstrated a convincing local control and overall survival benefit. Oncologists and GI workshops have in the present not had a major interest in the radiotherapy treatment of gastric cancer due to a number of factors. Primary because toxicities may be severe, second physicians may have low experience in definition of clinical target volume and in third perioperative chemotherapy is widely used in this indication. In Summary this issue should be used as guides for defining appropriate radiation planning treatment for the adjuvant postoperative therapy of gastric cancer. (authors)

    High-intensity focused ultrasound (HIFU) in combination with palliative standard therapy is an innovative and effective treatment option for pain reduction in patients with inoperable pancreatic cancer. Evaluation of the effects of additive ultrasound (US)-guided HIFU treatment in inoperable pancreatic cancer on the sensory and affective pain perception using validated questionnaries. In this study 20 patients with locally advanced inoperable pancreatic cancer and tumor-related pain were treated by US-guided HIFU (6 stage III, 12 stage IV according to UICC and 2 with local recurrence after surgery). Ablation was performed using the JC HIFU system (HAIFU, Chongqing, China) with an ultrasonic device for real-time imaging. Clinical assessment included evaluation of pain severity using validated questionnaires with particular attention to the pain sensation scale (SES) with its affective and sensory component and the numeric rating scale (NRS). The average pain reduction after HIFU was 2.87 points on the NRS scale and 57.3 % compared to the mean baseline score (n = 15, 75 %) in 19 of 20 treated patients. Four patients did not report pain relief, however, the previous opioid medication could be stopped (n = 2) or the analgesic dosage could be reduced (n = 2). No pain reduction was achieved in one patient. Furthermore, after HIFU emotional as well as sensory pain aspects were significantly reduced (before vs. 1 week after HIFU, p pain scales). US-guided HIFU can be used for effective and early pain relief and reduction of emotional and sensory pain sensation in patients with locally advanced pancreatic cancer.

    HER2 status is significant to trastuzumab therapy; however, it is difficult to determine HER2 status accurately with few pieces of biopsies from advanced gastric cancer (AGC) due to highly heterogeneity and invasive behaviour, which will be investigated in this study. Fifty-six patients with AGC were included in this study. Primary tumour tissues and matched plasmas before medication from 36 patients were retrospectively collected, and the other 20 patients with primary tumour tissues and paired plasmas were prospectively collected. HER2 expression and amplification in 56 tumour tissues were determined by immunohistochemistry (IHC) and dual in situ hybridisation (DISH), and HER2 copy number in 135 circulating tumour DNAs (ctDNAs) was judged by next-generation sequencing. For tumour tissues, HER2 amplification by DISH was most commonly found in patients with HER2 score 3+by IHC. For plasmas, HER2 amplification defined as HER2 copy number >2.22 was identified in 26 of 56 patients. There was a high concordance of HER2 amplification between ctDNA and tumour tissues, suggesting that ctDNA could function as an alternative to screen HER2-targeted population. Moreover, the changes of HER2 copy number in ctDNA could efficiently monitor trastuzumab efficacy, the power of which was superior to commonly used markers carcinoembryonic antigen (CEA) and CA199, suggesting its potential role in clinical practice. ctDNA for HER2 analysis was strongly recommended to serve as a surrogate to screen trastuzumab-suitable population and monitor trastuzumab efficacy.

    Fluoropyrimidine and platinum combination is the standard treatment for advanced or recurrent gastric cancer (AGC). However, fluoropyrimidine monotherapy is commonly used for elderly patients with AGC because of its good tolerability. In this multicenter retrospective study, we collected clinical data of AGC patients aged 70 years or older, treated with S-1 alone or S-1 plus cisplatin (SP) as the first-line treatment between January 2009 and December 2011. Propensity score matched cohorts (PSMC) were used for reducing the confounding effects to compare efficacy and safety between the two treatment groups. Cox regression analysis was performed to clarify the prognostic factors. PSMC (n = 109 in each group) were selected from among 444 eligible patients (S-1 group, 210; SP group, 234); the S-1 group included more patients deemed unfit for intensive chemotherapy than the SP group (e.g., higher age, poorer PS, poor renal function). In the PSMC, patients' characteristics were comparable between groups, except the male ratio (S-1 group, 64.2%; SP group, 77.1%; p = 0.04). No significant differences were observed in either overall survival [hazard ratio (HR) 0.93, p = 0.63] or progression-free survival (HR 1.09, p = 0.61). Severe adverse events (AEs) and hospitalization due to AEs were more frequent in the SP group than in the S-1 group (p strategy and explore applicability of the geriatric assessment for these patients.

    Response Evaluation Criteria in Solid Tumors (RECIST) guideline version 1.0 (RECIST 1.0) was proposed as a new guideline for evaluating tumor response and has been widely accepted as a standardized measure. With a number of issues being raised on RECIST 1.0, however, a revised RECIST guideline version 1.1 (RECIST 1.1) was proposed by the RECIST Working Group in 2009. This study was conducted to compare CT tumor response based on RECIST 1.1 vs. RECIST 1.0 in patients with advanced gastric cancer (AGC). We reviewed 61 AGC patients with measurable diseases by RECIST 1.0 who were enrolled in other clinical trials between 2008 and 2010. These patients were retrospectively re-analyzed to determine the concordance between the two response criteria using the κ statistic. The number and sum of tumor diameters of the target lesions by RECIST 1.1 were significantly lower than those by RECIST 1.0 (P<0.0001). However, there was excellent agreement in tumor response between RECIST 1.1 and RECIST 1.0 (κ=0.844). The overall response rates (ORRs) according to RECIST 1.0 and RECIST 1.1 were 32.7% (20/61) and 34.5% (20/58), respectively. One patient with partial response (PR) based on RECIST 1.0 was reclassified as stable disease (SD) by RECIST 1.1. Of two patients with SD by RECIST 1.0, one was downgraded to progressive disease and the other was upgraded to PR by RECIST 1.1. RECIST 1.1 provided almost perfect agreement with RECIST 1.0 in the CT assessment of tumor response of AGC.

    Systemic abrogation of TGF-β signaling results in tumor reduction through cytotoxic T lymphocytes activity in a mouse model. The administration of polysaccharide-Kureha (PSK) into tumor-bearing mice also showed tumor regression with reduced TGF-β. However, there have been no studies regarding the PSK administration to cancer patients and the association with plasma TGF-β. PSK (3 g/day) was administered as a neoadjuvant therapy for 2 weeks before surgery. In total, 31 advanced gastric cancer (AGC) patients were randomly assigned to group A (no neoadjuvant PSK; n=14) or B (neoadjuvant PSK therapy; n=17). Plasma TGF-β was measured pre- and postoperatively. The allocation factors were clinical stage (cStage) and gender. Plasma TGF-β ranged from 1.85–43.5 ng/ml (average, 9.50 ng/ml) in AGC, and 12 patients (38.7%) had a high value, >7.0 ng/ml. These patients were largely composed of poorly-differentiated adenocarcinoma with pathological stage III/IV. All the six elevated cases in group B showed a significant reduction of plasma TGF-β (from 21.6 to 4.5 ng/ml, on average), whereas this was not exhibited in group A. The cases within the normal limits of TGF-β remained unchanged irrespective of PSK treatment. Analysis of variance showed a statistically significant reduction in the difference of plasma TGF-β between groups A and B (P=0.019). PSK reduced the plasma TGF-β in AGC patients when the levels were initially high. The clinical advantage of PSK may, however, be restricted to specific histological types of AGC. Perioperative suppression of TGF-β by PSK may antagonize cancer immune evasion and improve patient prognosis in cases of AGC. PMID:26137253

    A change in tumor size is a well-validated and commonly used value for evaluating response to chemotherapy in cancer. Metabolic changes induced by chemotherapy are related to prognosis in several tumor types. However, the clinical implication of metabolic changes in patients with advanced gastric cancer (AGC) undergoing chemotherapy remains unclear. We aimed to evaluate response of tumor size and metabolism in AGC during chemotherapy and to reveal the relationship between them in view of their impact on patient survival. Methods: We prospectively enrolled patients with AGC before the initiation of first-line palliative chemotherapy. Using baseline and follow-up contrast-enhanced CT and 18 F-FDG PET, we assessed the tumor diameter, SUV max , and total lesion glycolysis in each lesion and their changes during chemotherapy at the same time. We included all lesions with the maximal longest diameters over 1 cm on CT, and each lesion was evaluated by matched 18 F-FDG PET. We analyzed the association between changes in tumor metabolism and tumor size and performed outcome analysis on overall survival (OS) and progression-free survival (PFS). Results: Seventy-four patients were enrolled, and the number of all lesions included in this study was 620. Compared with adenocarcinomas, poorly cohesive carcinomas demonstrated lower SUV max irrespective of tumor size ( P chemotherapy had a linear correlation with the changes in tumor size of each lesion, and a 30% tumor size reduction was associated with a 50% SUV max reduction ( P chemotherapy correlated with changes in tumor size in AGC. Considering both changes in metabolism and size could help predict a more accurate prognosis for AGC patients undergoing chemotherapy. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

    Purpose: To determine in a Phase II trial whether preoperative irinotecan-cisplatin (IC) followed by concurrent IC therapy and radiotherapy (IC/RT) improved outcome in patients with resectable, locally advanced gastric adenocarcinoma (GC) or esophagogastric junction cancer (EGJC). Patients and Methods: Patients with resectable Stage II-IV, M0 GC or EGJC made up the study population. The primary endpoint was pathologic complete response (pCR). Two courses of IC (irinotecan, 65mg/m 2 ; cisplatin, 30mg/m 2 on Days 1 and 8 every 21 days) were given. Patients without progression then received IC/RT, consisting of daily radiotherapy (45Gy) with concurrent IC (irinotecan, 65mg/m 2 ; cisplatin, 30mg/m 2 on Days 1, 8, 15, and 22). Surgical resection was performed, if feasible, 5-8 weeks after the end of radiotherapy. Results: Twenty-three patients were included in the study: 10 with EGJC and 13 with GC. Two patients (9%) achieved pCR. The incidences of Grade 3-4 toxicities were as follows: IC: neutropenia 35% (febrile 13%), anemia 22%, diarrhea 22%, emesis 8%; IC/RT: neutropenia 52% (febrile 5%), asthenia 19%, anemia 9%, emesis 9%, diarrhea 5%, cardiotoxicity 5%. No patients died during IC or IC/RT. R0 resection was achieved in 15 patients (65%). Median survival was 14.5 months, and the actuarial 2-year survival rate was 35%. Conclusions: Preoperative IC followed by IC/RT resulted in moderate response and resection rates with mild toxicity in patients with GC and EGJC.

    Early metabolic response on 18-fluorodeoxyglucose-positron emission tomography (FDG-PET) during neoadjuvant chemotherapy is PET non-responders have poor outcomes whether continuing chemotherapy or proceeding directly to surgery. Use of PET may identify early treatment failure, sparing patients from inactive therapy and allowing for crossover to alternative therapies. We examined the effectiveness of PET directed switching to salvage chemotherapy in the PET non-responders. Patients with locally advanced resectable FDG-avid gastric or gastroesophageal junction (GEJ) adenocarcinoma received bevacizumab 15 mg/kg, epirubicin 50 mg/m(2), cisplatin 60 mg/m(2) day 1, and capecitabine 625 mg/m(2) bid (ECX) every 21 days. PET scan was obtained at baseline and after cycle 1. PET responders, (i.e., ≥35% reduction in FDG uptake at the primary tumor) continued ECX + bev. Non-responders switched to docetaxel 30 mg/m(2), irinotecan 50 mg/mg(2) day 1 and 8 plus bevacizumab every 21 days for 2 cycles. Patients then underwent surgery. The primary objective was to improve the 2-year disease free survival (DFS) from 30% (historical control) to 53% in the non-responders. Twenty evaluable patients enrolled before the study closed for poor accrual. Eleven were PET responders and the 9 non-responders switched to the salvage regimen. With a median follow-up of 38.2 months, the 2-year DFS was 55% [95% confidence interval (CI), 30-85%] in responders compared with 56% in the non-responder group (95% CI, 20-80%, P=0.93). The results suggest that changing chemotherapy regimens in PET non-responding patients may improve outcomes. Results from this pilot trial are hypothesis generating and suggest that PET directed neoadjuvant therapy merits evaluation in a larger trial.

    Full Text Available Abstract Background The main goal when managing patients with inoperable oesophageal cancer is to restore and maintain their oral nutrition. The aim of the present study was to assess the value of endoscopic palliation of dysphagia in patients with oesophageal cancer, who either due to advanced stage of the disease or co-morbidity are not suitable for surgery. Patients and methods All the endoscopic palliative procedures performed over a 5-year period in our unit were retrospectively reviewed. Dilatation and insertion of self-expandable metal stents (SEMS were mainly used for tight circumferential strictures whilst ablation with Nd-YAG laser was used for exophytic lesions. All procedures were performed under sedation. Results Overall 249 palliative procedures were performed in 59 men and 40 women, with a median age of 73 years (range 35 – 93. The median number of sessions per patient was 2 (range 1 – 13 sessions. Palliation involved laser ablation alone in 24%, stent insertion alone in 22% and dilatation alone in 13% of the patients. In 41% of the patients, a combination of the above palliative techniques was applied. A total of 45 SEMS were inserted. One third of the patients did not receive any other palliative treatment, whilst the rest received chemotherapy, radiotherapy or chemoradiotherapy. Swallowing was maintained in all patients up to death. Four oesophageal perforations were encountered; two were fatal whilst the other two were successfully treated with covered stent insertion and conservative treatment. The median survival from diagnosis was 10.5 months (range 0.5–83 months and the median survival from 1st palliation was 5 months (range 0.5–68.5 months. Conclusion Endoscopic interventions are effective and relatively safe palliative modalities for patients with oesophageal cancer. It is possible to adequately palliate almost all cases of malignant dysphagia. This is achieved by expertise in combination treatment.

    Until now, no standard chemotherapy has been widely accepted for advanced gastric cancer (GC). The current research aimed to compare folinic acid, fluorouracil with irinotecan (mFOLFIRI) or with oxaliplatin (mFOLFOX7) as first-line treatments in patients with locally advanced GC in an open, randomized, phase II study. Previously untreated metastatic or recurrent GC patients with measurable disease received mFOLFIRI (arm A) or mFOLFOX7 (arm B) every 2 weeks. The defined second-line treatment was mFOLFOX7 for arm A and mFOLFIRI for arm B. Primary endpoint was progression-free survival (PFS), and secondary endpoints were overall survival (OS), disease control rate (DCR) and toxicity. The evaluable population consisted of 128 patients (54 in arm A; 74 in arm B). Median PFS of arm A was 2.9 months (m) (95% confidence interval, CI , 1.9 to 4.1 m) versus 4.1 m (95% CI , 3.2 to 4.8 m) for arm B ( p = 0.109). Median OS was 9.9 months (95% CI , 6.0 to 13.5 m) for arm A versus 12.0 m for arm B (95% CI , 10.3 to 13.7m; p = 0.431). DCRs for arm A and arm B were 59.3% and 66.3%, respectively ( p = 0.850). In subgroup analysis of the patients who completed both treatment lines per protocol, the median first-line PFS was 2.1 m for the mFOLFIRI/mFOLFOX7arm versus 8.0 m for the mFOLFOX7/mFOLFIRI arm ( p = 0.053), and the median second-line PFS values were 1.2 m versus 5.1 m ( p = 0.287). Total PFS and OS were 8.1m and 11.0 m for the mFOLFIRI/mFOLFOX7 group compared with 12.2m and 20.2 m for the mFOLFOX7/mFOLFIRI group ( p = 0.008, p = 0.030). Both regimens were well-tolerated with acceptable and manageable toxicities. Hence, there was no significant difference in the PFS or DCR. However, mFOLFOX7 followed by mFOLFIRI might have a better OS.

    A total of 25 cases with early gastric carcinoma, of which 10 cases were followed by gastrectomy, were given a combined radiotherapy with 5-Fu, Ft 207 or MFC at Miyagi Seijinbyo Center. Histologic examinations of biopsy specimens revealed the disappearance of cancer cells in five (42%) of 12 cases and those of serial specimens of the resected stomach showed the complete disappearance of cancer cells in three (27%) of 11 lesions (10 cases). Five year survival rate in 15 non-resected cases was only 30%. From these results, it was suggested that a combined radiotherapy of early gastric carcinoma should not be chosen as a curative treatment procedure but it might be valuable, if early carcinoma was thought to be inoperable because of other medical reasons.

    Purpose: To assess the efficacy of self-expanding metallic stents in treating inoperable gastric and duodenal stenoses during follow-up and to evaluate the complications encountered.Methods: A total of 31 patients suffering from gastroduodenal obstruction (29 malignant, 2 benign) were treated with a self-expanding metallic stent (Wallstent). In 24 cases insertion was by the peroral route, in seven cases via gastrostomy.Results: All the strictures were successfully negotiated under fluoroscopic guidance without having to resort to endoscopy. A total of 27 patients (87%) were able to resume a regular diet, a soft diet, or a liquid diet orally. Complications included one case of stent malpositioning, one case of leakage of ascitic fluid through the gastrostomy orifice, one case of perforation and fistula to the biliary tree, and two cases of hematemesis. In two patients (6%) additional stents were implanted to improve patency. In all patients follow-up was maintained until death. Recurrence of symptoms immediately before death occurred in seven cases (23%). Mean survival time of patients was 13.3 weeks (SE ± 4.6).Conclusions: The deployment of gastroduodenal stents resulted in good palliation of inoperable gastric and duodenal stenoses. Certain technical aspects, e.g., adaptation of stents to bowel morphology, is critical to proper stent function and avoidance of complications

    2017-01-01

    Full Text Available History of present illness: A 12-year-old female with no past medical history presented with abdominal pain for 3 months. The pain was intermittent, located at the epigastric region, non-radiating, fluctuating intensity up to 8/10, and had worsened over the past month. She did not have fever, nausea, vomiting, diarrhea, constipation, or blood in her stool. The patient also endorsed hair loss over the same time period and noted that her previously long hair was now short and thin. On exam, patient was noted to have shoulder-length hair, a soft, non-distended abdomen with mild tenderness to the epigastric region, and a 5cm hard mass palpated at the epigastrium. Significant findings: In the abdominal radiograph, a nonspecific and non-obstructive bowel gas pattern with no air-fluid level was noted, however the stomach was distended with soft tissue. The CT abdomen/pelvis revealed a distended stomach with undigested heterogeneous contents (presumed bezoar. Discussion: A bezoar is a mass of incompletely digested material typically originating in the stomach and consisting of vegetable fibers, hair, or drugs.1 Bezoars develop after ingested foreign material accumulates in the gastrointestinal tract due to indigestibility, gastric outlet obstruction, or intestinal stasis. Trichobezoars are comprised of hair and classically form in young females with an underlying psychiatric disorder resulting in the urge to pull one’s hair out (trichotillomania and swallow it (trichophagia.2,3 Gastric bezoars are rare with an approximate incidence of 0.3 percent of patients undergoing upper endoscopy.4 Patients tend to remain asymptomatic for long periods, but may develop abdominal pain, nausea/vomiting, early satiety, anorexia, and weight loss.5 Complications may include gastrointestinal ulcerations, perforations, intussusception, pancreatitis, obstructive jaundice, and death.6-8 The diagnosis of a gastric bezoar can be made using plain films, ultrasound, or CT, and

    To evaluate the radiologic findings of gastric MALToma, and to correlate these with its pathologic findings. We retrospectively reviewed the pathologic slides of gastrectomy and gastroscopic biopsy specimens obtained between 1982 and 1996, and collected nine cases of gastric MALToma. Eight of these had been surgically confirmed, and one had been diagnosed by gastroscopic biopsy. A gastrointestinal series comprised eight cases; five involved sonography and five, CT. The lesions were located at the body in five cases, at the antrum in one, and at the body and antrum in three cases. Pathologic diagnosis was low grade MALToma in four cases, and mixed high and low grade MALToma in five cases. Initial radiologic diagnosis was gastric lymphoma in four cases, early gastric carcinoma in three, and advanced gastric carcinoma in two cases. On retrospective analysis, radiologic diagnosis was changed to lymphoma in both cases initially diagnosed as advanced gastric carcinomas. One case showed marked thickening of the gastric wall, with poor enhancement on CT, and the other case showed a very small and shallow ulcer in comparison to diffuse infiltration of tumor in the upper gastrointestinal series. The final radiologic diagnosis was gastric lymphoma in six cases, and early carcinoma in three. Radiologic findings of gastric MALToma were EGC II c-like lesion in three cases, marked gastric wall thickening in two, multiple discrete lesions in two, hyperugosity of gastric folds with discrete lesions in one, and diffuse infiltrative lesion with small ulcer in one case. The pathologic diagnosis of gastric MALToma was made by the presence of lymphoepithelial lesions, centrocyte-like cells, reactive follicles, plasma cell infiltration, and follicular colonization. There were no significant correlations between radiologic findings and pathologic results such as depth of tumor invasion, low grade MALToma or mixed high and low grade MALToma. There are no specific radiologic characteristics

    In this review, we focus on post-progression survival after first-line chemotherapy of advanced gastric cancer, and particularly the differences between Japan and the rest of the world. We reviewed 15 recent phase III trials of which 4 were solely recruited from Japanese and 11 from rest of the world. The patient characteristics age, performance status, previous gastrectomy and the number of metastatic sites were similar in Japan and rest of the world. However, the diffuse histological type was more common in Japan. While overall survival was longer in Japan (10.5-14.1 vs. 7.9-12.2 months), progression-free survival tended to be shorter in Japan (3.6-6.0 vs. 3.1-7.4 months). Post-progression survival calculated as the difference between median overall survival and progression-free survival was clearly longer in Japan (6.9-8.6 vs. 2.4-6.2 months). The proportion of patients receiving second-line chemotherapy (%2nd-CX) was quite different in Japan and rest of the world (69-85% vs. 11-59%). Correlations between %2nd-CX and post-progression survival were strong (Spearman's rank correlation coefficient; ρ = 0.86, P < 0.001). Correlations between %2nd-CX and ratio of post-progression survival to total overall survival were also strong (ρ = 0.84, P < 0.001). Because a survival benefit of second-CX was documented in several phase III trials, it can be concluded that higher %2nd-CX partly contributed to extended post-progression survival. However, considering that second-CX increased survival only by ~1.5 months at median, other factors such as third-line chemotherapy may have some influences to prolonged post-progression survival. © The Author 2017.

    An extensive crosstalk co-regulates the Hippo and Wnt pathway. Preclinical studies revealed that the Hippo transducers YAP/TAZ mediate a number of oncogenic functions in gastric cancer (GC). Moreover, comprehensive characterization of GC demonstrated that the Wnt pathway is targeted by oncogenic mutations. On this ground, we hypothesized that YAP/TAZ- and Wnt-related biomarkers may predict clinical outcomes in GC patients treated with chemotherapy. In the present study, we included 86 patients with advanced GC treated with first-line chemotherapy in prospective phase II trials or in routine clinical practice. Tissue samples were immunostained to evaluate the expression of YAP/TAZ. Mutational status of key Wnt pathway genes (CTNNB1, APC and FBXW7) was assessed by targeted DNA next-generation sequencing (NGS). Survival curves were estimated and compared by the Kaplan-Meier product-limit method and the log-rank test, respectively. Variables potentially affecting progression-free survival (PFS) were verified in univariate Cox proportional hazard models. The final multivariate Cox models were obtained with variables testing significant at the univariate analysis, and by adjusting for all plausible predictors of the outcome of interest (PFS). We observed a significant association between TAZ expression and Wnt mutations (Chi-squared p = 0.008). Combined TAZ expression and Wnt mutations (TAZ pos /WNT mut ) was more frequently observed in patients with the shortest progression-free survival (negative outliers) (Fisher p = 0.021). Uni-and multivariate Cox regression analyses revealed that patients whose tumors harbored the TAZ pos /WNT mut signature had an increased risk of disease progression (univariate Cox: HR 2.27, 95% CI 1.27-4.05, p = 0.006; multivariate Cox: HR 2.73, 95% CI 1.41-5.29, p = 0.003). Finally, the TAZ pos /WNT mut signature negatively impacted overall survival. Collectively, our findings indicate that the oncogenic YAP/TAZ-Wnt crosstalk may be

    Full Text Available Abstract Background The objective of this study was to evaluate the efficacy and toxicity of infusional 5-fluorouracil (5-FU, folinic acid and oxaliplatin (modified FOLFOX-6 in patients with advanced gastric cancer (AGC, as first-line palliative combination chemotherapy. We also analyzed the predictive or prognostic value of germline polymorphisms of candidate genes associated with 5-FU and oxaliplatin. Methods Seventy-three patients were administered a 2 hour infusion of oxaliplatin (100 mg/m2 and folinic acid (100 mg/m2 followed by a 46 hour continuous infusion of 5-FU (2,400 mg/m2. Genomic DNA from the patients' peripheral blood mononuclear cells was extracted. Ten polymorphisms within five genes were investigated including TS, GSTP, ERCC, XPD and XRCC. Results The overall response rate (RR was 43.8%. Median time to progression (TTP and overall survival (OS were 6.0 months and 12.6 months, respectively. Toxicities were generally tolerable and manageable. The RR was significantly higher in patients with a 6-bp deletion homozygote (-6 bp/-6 bp in TS-3'UTR (55.0% vs. 30.3% in +6 bp/+6 bp or +6 bp/-6 bp, p = 0.034, and C/A or A/A in XPD156 (52.0% vs. 26.1% in C/C, p = 0.038. The -6 bp/-6 bp in TS-3'UTR was significantly associated with a prolonged TTP and OS. In a multivariate analysis, the 6-bp deletion in TS-3'UTR was identified as an independent prognostic marker of TTP (hazard ratio = 0.561, p = 0.032. Conclusion Modified FOLFOX-6 chemotherapy appears to be active and well tolerated as first line chemotherapy in AGC patients. The 6-bp deletion in TS-3'UTR might be a candidate to select patients who are likely to benefit from 5-FU based modified FOLFOX-6 in future large scale trial.

    To investigate the causes of gastric wall shortening in early gastric cancer, upper gastrointestinal study was correlated with pathologic findings. We evaluated 41 cases (M:F = 1.7:1, average age = 49) of early gastric cancer, retrospectively. The gastric wall shortening were classified as Grade I; none, Grade II; intermediate, and Grade III; prominent. Pathologic findings such as size of lesions, depth of tumor invasion, degree of the submucosal fibrosis, degree of thickness of the submucosa and muscularis propria, and morphologic patterns of lesions including conversing mucosal folds were correlated with the degree of gastric wall shortening on upper gastrointestinal series. Submucosal fibrosis was present in 4 cases in Grade I (n = 21), 4 cases in Grade II (n = 6) and 8 cases in Grade III (n = 10). Positive conversing mucosal folds were seen in 5 cases in Grade I (n = 17), 0 case in Grade II (n = 2) and 9 cases in Grade III (n = 9). Gastric wall shortening was significantly associated with submucosal fibrosis and conversing mucosal folds of early gastric cancer. (ρ = 0.0001, and ρ = 0.02, respectively) Upper gastrointestinal finding of gastric wall protrusion in patients with early gastric cancer should not misinterprete as advanced gastric cancer since the finding could be a result of submucosal fibrosis

    Lung cancer is one of the most commonly diagnosed cancers, and is a leading cause of cancer mortality world-wide. Due to lack of early specific symptoms, the majority of patients present with advanced, inoperable disease and five-year relative survival across all stages of non-small cell lung cancer (NSCLC) is 14%. People with lung cancer also report higher levels of symptom distress than those with other forms of cancer. Several benefits for survival and patient reported outcomes are reported from physical activity and exercise in other tumour groups. We report the protocol for a study investigating the benefits of exercise, behaviour change and symptom self-management for patients with recently diagnosed, inoperable, NSCLC. This multi-site, parallel-group, assessor-blinded randomised controlled trial, powered for superiority, aims to assess functional and patient-reported outcomes of a multi-disciplinary, home-based exercise and supportive care program for people commencing treatment. Ninety-two participants are being recruited from three tertiary-care hospitals in Melbourne, Australia. Following baseline testing, participants are randomised using concealed allocation, to receive either: a) 8 weeks of home-based exercise (comprising an individualised endurance and resistance exercise program and behaviour change coaching) and nurse-delivered symptom self-management intervention or b) usual care. The primary outcome is the between-group difference in the change in functional exercise capacity (six-minute walk distance) from baseline to post-program assessment. Secondary outcomes include: objective and self-reported physical activity levels, physical activity self-efficacy, behavioural regulation of motivation to exercise and resilience, muscle strength (quadriceps and grip), health-related quality of life, anxiety and depression and symptom interference. There is a lack of evidence regarding the benefit of exercise intervention for people with NSCLC, particularly

    The National Institute for Health and Care Excellence (NICE) invited the company that manufactures ramucirumab (Cyramza ® , Eli Lilly and Company) to submit evidence of the clinical and cost effectiveness of the drug administered alone (monotherapy) or with paclitaxel (combination therapy) for treating adults with advanced gastric cancer or gastro-oesophageal junction (GC/GOJ) adenocarcinoma that were previously treated with chemotherapy, as part of the Institute's single technology appraisal (STA) process. Kleijnen Systematic Reviews Ltd (KSR), in collaboration with Erasmus University Rotterdam, was commissioned to act as the Evidence Review Group (ERG). This paper describes the company's submission, the ERG review, and NICE's subsequent decisions. Clinical effectiveness evidence for ramucirumab monotherapy (RAM), compared with best supportive care (BSC), was based on data from the REGARD trial. Clinical effectiveness evidence for ramucirumab combination therapy (RAM + PAC), compared with paclitaxel monotherapy (PAC), was based on data from the RAINBOW trial. In addition, the company undertook a network meta-analysis (NMA) to compare RAM + PAC with BSC and docetaxel. Cost-effectiveness evidence of monotherapy and combination therapy relied on partitioned survival, cost-utility models. The base-case incremental cost-effectiveness ratio (ICER) of the company was £188,640 (vs BSC) per quality-adjusted life-year (QALY) gained for monotherapy and £118,209 (vs BSC) per QALY gained for combination therapy. The ERG assessment indicated that the modelling structure represented the course of the disease; however, a few errors were identified and some of the input parameters were challenged. The ERG provided a new base case, with ICERs (vs BSC) of £188,100 (monotherapy) per QALY gained and £129,400 (combination therapy) per QALY gained and conducted additional exploratory analyses. The NICE Appraisal Committee (AC), considered the company's decision problem was in

    The authors evoke some characteristics of the basal cell carcinoma (slow evolution, local morbidity) and report and discuss the case of a giant basal cell trunk carcinoma, associated with several symptoms (pain, bleeding, anaemia), already metastatic at the moment of diagnosis, and locally treated by irradiation. Due to its size and expansion, this carcinoma was considered as inoperable. An external radiotherapy has been performed and resulted in a significant clinical tumour reduction. But the metastatic risk is high in such cases. Radiotherapy is then a therapeutic option for a local treatment with a durable efficiency. Short communication

    Although many genetic alterations have been reported in gastric cancer, it is not known whether all gastric tumors are capable of indefinite proliferative potential, e.g., immortality. The expression of telomerase and stabilization of telomeres are concomitant with the attainment of immortality in tumor cells; thus, the measurement of telomerase activity in clinically obtained tumor samples may provide important information useful both as a diagnostic marker to detect immortal cancer cells in clinical materials and as a prognostic indicator of patient outcome. Telomerase activity was analyzed in 66 primary gastric cancers with the use of a PCR-based assay. The majority of tumors (85%) displayed telomerase activity, but telomerase was undetectable in 10 tumors (15%), 8 of which were early stage tumors. Most of the tumors with telomerase activity were large and of advanced stages, including metastases. Survival rate of patients of tumors with detectable telomerase activity was significantly shorter than that of those without telomerase activity. Alterations of telomere length (reduced/elongated terminal restriction fragments) were detected in 14 of 66 (21%) gastric cancers, and all 14 had telomerase activity. Cellular DNA contents revealed that all 22 aneuploid tumors had detectable telomerase activity. The present results indicate that telomerase activation may be required as a critical step in the multigenetic process of tumorigenesis, and that telomerase is frequently but not always activated as a late event in gastric cancer progression.

    Apparatus for rendering at least a portion of a device inoperable may include a containment structure having a first compartment that is configured to receive a device therein and a movable member configured to receive a cartridge having reactant material therein. The movable member is configured to be inserted into the first compartment of the containment structure and to ignite the reactant material within the cartridge. Methods of rendering at least a portion of a device inoperable may include disposing the device into the first compartment of the containment structure, inserting the movable member into the first compartment of the containment structure, igniting the reactant material in the cartridge, and expelling molten metal onto the device.

    2016-10-01

    Intrathoracic stomach is a rare and serious congenital abnormality. The anomaly may be complicated by gastric volvulus and can lead to ischemic gastric infarction in the neonate. If diagnosed antenatally, neonatal management can be planned in advance so as to reduce morbidity. This anomaly must be differentiated from the more common congenital diaphragmatic hernia, as associated pulmonary hypoplasia is common in the latter and rare with gastric herniation. We report a case of intrathoracic stomach in a neonate without volvulus, fortunately a rare entity which was managed operatively, and the child has been under regular follow-up.

  1. Gastric carcinoma: when is palliative gastrectomy justified?

    2011-12-01

    Full Text Available Gastric carcinoma is frequently diagnosed with an advanced stage of non-curable tumor growth characterized by infiltration of the gastric serosa, peritoneal tumor spread and/or metastases within lymph nodes and liver. Currently, there is a controversy on the value of palliative resection with regard to the safety and benefit to the patient outcome. Based on the available literature, this overview summarizes the various aspects and interprets the limited data on the palliative resection of gastric carcinoma. It turns out that the available study results may indicate potential for an improved quality of life and a prolongation of survival if an acceptable morbidity and mortality are present.

An attempt was made in this review to discuss the classification, pathophysiology, diagnosis and treatment of gastric ulcer in dogs. Early surgical advances in the management of peptic ulcers are emphasized that were then subsequently replaced by pharmacological treatment (histamine H2-receptor antagonists, proton pump inhibitors and considered as the major strategy against the acid disorders.

    In recent 5 years, we have experienced 24 cases of advanced gastric cancer associated with obstructive uropathy. Included were 19 cases of undifferentiated, 3 cases of differentiated and 2 cases of unknown histological type. Obstructive uropathy is diagnosed based on the typical radiological findings such as dilatation and delayed demonstration of the upper collecting systems. Pathologically, undifferentiated type of gastric cancer had tendency to spread infiltratively along the vessels, nerves and the lymphatics without alteration of the ordinary anatomical structures. In such cases, mucosal surface of the urinary tract tended to be spared in spite of extensive tumor invasion. It was proven that several radiological findings were characteristic of urinary tract involvement secondary to gastric cancer. Either thread-like ureteral stricture by IVU or ring-like appearance of the ureter by CT is one of those typical findings. Renal sinus involvement may occur continuously to diffuse retroperitoneal invasion and it appears as a thickened wall of renal pelvis or soft tissue mass directly extending into the fatty tissue of renal sinus by CT. In such cases IVU has less diagnostic ability because of the lack of mucosal destruction. If the urinary bladder is involved, it typically shows chestnut-bur appearance by IVU and diffuse wall thickening by CT. In cases of advanced gastric cancer, particularly in cases of histologically undifferentiated type, CT and IVU images should be carefully interpreted in consideration of the infiltrative part of tumor extention.

    Hundred patients with inoperable cancer of the cervix, who had been treated by primary irradiation, were reviewed with regard to biorhythm on the days of radium application. 5-year survival was lower in patients with unfavorable biorhythm; the differences, however, were not significant. It is concluded that the calculation of biorhythm for the day of radiotherapy has little or no influence on the results of therapy. (orig.) [de

    2014-01-01

    Full Text Available Introduction: The treatment of choice in cancer esophagus is controversial. Radiation therapy oncology group, Eastern cooperative oncology group and Cochrane studies have shown superiority of concurrent chemoradiation in inoperable carcinoma esophagus. In these studies full dose cisplatin was given every 3 weeks along with radiotherapy and hence had some toxicity. So, we started treating inoperable carcinoma esophagus patients with low dose weekly cisplatin given concurrently with radiotherapy aiming at low toxicity and similar results. Materials and Methods: A total of 31 cases of inoperable cases of carcinoma esophagus were treated with once weekly cisplatin 30 mg/m 2 along with radiotherapy 60 Gy in 30 fractions in 6 weeks on Telecobalt/Linear accelerator. Results : w0 e could achieve lower toxicity with 80%, 35% and 19% with 1, 2, and 3 year′s survival with a median survival of 18 months. So, we conclude that this regimen is better than 3 weekly chemotherapy regimen as is better tolerated with less toxicity and similar outcome.

    Background: Nicotinamide and carbogen have been shown to enhance the radiation effect in tumour models. Purpose: Prospective evaluation of the toxicity and efficacy of carbogen and nicotinamide with external beam radiotherapy in the management of inoperable glioblastoma. Patients and methods: From April 1995 to December 1997, 33 patients with inoperable biopsy-proven glioblastoma multiforme (GBM) were enrolled in a phase II trial, to undergo radiotherapy (59.4 Gy in 1.8 Gy/fraction), intra-arterial cerebral chemotherapy (ACNU 100 mg/m 2 , three cycles), carbogen breathing (15 l/min), and nicotinamide (85 mg/kg). This experimental group was compared to a control group of 38 patients with inoperable GBM treated with radiotherapy and three cycles of nitrosourea-based chemotherapy from January 1990 to March 1995, in our institution. Results: In the experimental group, carbogen breathing was well tolerated, but only 51.5% of patients completed daily nicotinamide over the 6.5-week treatment period. Nausea and vomiting were the most frequent side effects of nicotinamide. No significant difference in overall survival was observed among the two treatment groups: median survival times were 36.7 and 35.3 weeks for patients treated with carbogen and nicotinamide, and for those treated in the control group, respectively. Conclusion: The association of carbogen and nicotinamide with radiotherapy is feasible, but tolerable only in 51.5% of patients with GBM. Carbogen and nicotinamide did not appear to modify the evolution of glioblastoma

    Alterations in the immune response of patients with autoimmune diseases may predispose to malignancies, and a link between chronic autoimmune gastritis and gastric cancer has been reported in many studies. Intestinal metaplasia with dysplasia of the gastric corpus-fundus mucosa and hyperplasia of chromaffin cells, which are typical features of late-stage autoimmune gastritis, are considered precursor lesions. Autoimmune gastritis has been associated with the development of two types of gastric neoplasms: intestinal type and type I gastric carcinoid. Here, we review the association of autoimmune gastritis with gastric cancer and other autoimmune features present in gastric neoplasms. PMID:29373557

    A D2 lymphadenectomy can be considered standard of surgical care for advanced resectable gastric cancer. Currently, several multimodality strategies are used, including postoperative monochemotherapy in Asia, postoperative chemoradiotherapy in the United States, and perioperative chemotherapy in Europe. As the majority of gastric cancer patients are treated outside the framework of clinical trials, quality assurance programs, including referral to high-volume centers and clinical auditing are needed to improve gastric cancer care on a nationwide level.

    Full Text Available Background: there are few studies in the literature comparing laparoscopic versus open Gastrectomy, predominantly for advanced gastric cancer (AGC. Most of the available studies and meta-analysis compare both approaches in the early gastric cancer. The meta-analysis, here presented, compares the clinical outcomes between these two procedures for AGC. Objectives: to evaluate the current status of both partial and total laparoscopic gastrectomy (LG, with regard to its short and long-term outcomes by comparing it to conventional open gastrectomy (OG for AGC. Data sources and review methods: original articles published in English language from January 1991 to October 2009 were searched in the Medline, Embase, Current Contents, Science Citation Index databases and Cochrane Controlled Trials Register. All articles comparing LG and OG for AGC were included, and those comparing outcomes only for early gastric cancer (EGC were excluded. Clinical appraisal and data extraction were conducted independently by 3 reviewers. Statistical analysis was carried out following the DerSimonian-Laird random effects model. Results: out of 2,344 studies, 7 studies were selected. One prospective randomized controlled trial, one comparative prospective study and five comparative retrospective studies were analyzed. These studies include a total of 452 patients with gastric cancer, 174 patients in the LG and 278 in the OG. The analyzed result variables were operative time, operative blood loss, hospital postoperative stay, number of dissected lymph nodes and cancer-related mortality risk. Compared to OG, LG was a longer procedure: weighted mean difference (WMD 44 minutes; 95% confidence interval (CI 20 to 69; I-squared = 91.6%, but was associated with a lower blood loss (WMD -122 cc; 95% CI -208 to -37; I-squared = 90.8%; this was more significant for hospital operative stay (WMD -6.2 days; 95% CI -9.4 to -2.8; I-squared = 67.8%. Moreover there were no significant

    During the two year period from January 1985 to December 1986, 161 cases were confirmed as early gastric cancer by pathologic mapping at Seoul National University Hospital. Among them, the authors reviewed 104 cases of early gastric cancer for the evaluation of diagnostic value of double contrast upper gastrointestinal series. Early gastric cancer was most common in 5th and 6th decade (64%) and male to female ratio was 2:1. Double contrast upper GI series could detect 97 out of 104 cases (93%). Among them, 62 cases were diagnosed as early gastric cancer, 32 as advanced gastric cancer and 3 as benign lesion. Detection rate according to the size was 100% in lesion larger than 2cm and 87% in lesion smaller than 2cm. Predictability of early gastric cancer according to size was 66% in lesion smaller than 3cm and 43% in lesion larger than 3cm. Detection rate according to the location of the tumor was almost similar between gastric body (94%) and antrum (93%), however was very low in anterior wall lesion (70%). Predictability of early gastric cancer was 69% in gastric body lesion, 52% in gastric antral lesion and 44% in greater curvature lesion. Detection rate according to the type of macrospecimen was 100% in type I, III and IIc+III. Type IIb showed the lowest detection rate (75%). Predictability of early gastric cancer was high in type IIc (68%) and low in type I (20%)

    Full Text Available Several drugs and their associations are being used for adjuvant or complementary chemotherapy with the aim of improving results of gastric cancer treatment. The objective of this study was to verify the impact of these drugs on nutrition and on survival rate after radical treatment of 53 patients with gastric cancer in stage III of the TNM classification. A control group including 28 patients who had only undergone radical resection was compared to a group of 25 patients who underwent the same operative technique followed by adjuvant polychemotherapy with FAM (5-fluorouracil, Adriamycin, and mitomycin C. In this latter group, chemotherapy toxicity in relation to hepatic, renal, cardiologic, neurological, hematologic, gastrointestinal, and dermatological functions was also studied. There was no significant difference on admission between both groups in relation to gender, race, macroscopic tumoral type of tumor according to the Borrmann classification, location of the tumor in the stomach, length of the gastric resection, or response to cutaneous tests on delayed sensitivity. Chemotherapy was started on average, 2.3 months following surgical treatment. Clinical and laboratory follow-up of all patients continued for 5 years. The following conclusions were reached: 1 The nutritional status and incidence of gastrointestinal manifestation were similar in both groups; 2 There was no occurrence of cardiac, renal, neurological, or hepatic toxicity or death due to the chemotherapeutic method per se; 3 Dermatological alterations and hematological toxicity occurred exclusively in patients who underwent polychemotherapy; 4 There was no significant difference between the rate and site of tumoral recurrence, the disease-free interval, or the survival rate of both study groups; 5 Therefore, we concluded, after a 5-year follow-up, chemotherapy with the FAM regimen did not increase the survival rate.

    Full text: In this paper we present our early experience with a new radio-conjugate, namely rhenium-188 HDD Lipiodol (Re-188 lipiodol). Imported radiopharmaceuticals are generally expensive, particularly for developing countries. A Tungsten (W-188-Re 188) generator obtained from ORNL (Oak Ridge National Laboratory, Tennessee, USA) allows us on-site production of a beta emitting therapeutic isotope (Re-188) for up to 6 months from a single generator. The objectives of this study were to establish the safety of trans-arterial Re-188 lipiodol in patients with inoperable HCC, and determine the adverse effects and efficacy for this radio-conjugate treatment in a multi-center study of patients with advanced HCC. A multi-center study was sponsored by the International Atomic Energy Agency (Vienna) to assess the safety and efficacy of trans-arterial Re-188 HDD conjugated lipiodol (radio-conjugate) in the treatment of patients with inoperable hepatocellular carcinoma (HCC), The radio-conjugate was prepared by using a HDD (4-hexadecyl 1-2, 9, 9-tetramethyl-4, 7-diaza-1, 10-decanethiol) kit developed in Korea, and lipiodol. Over a period of eighteen months seventy patients received at least one treatment of radio-conjugate. Some patients were re-treated if there was no evidence of disease progression. The level of radio-conjugate administered was based on radiation-absorbed dose to critical normal organs, calculated following a 'scout' dose of radio-conjugate. The organs at greatest risk for radiation toxicity are the normal liver, the lung and the bone marrow. A specially designed spreadsheet was used to determine maximum tolerated activity (MTA), defined as the amount of radioactivity calculated to deliver no more than 12 Gray (Gy) to lungs, or 30 Gy to liver, or 1.5 Gy to bone marrow. These doses have been found to be safe in multiple trials using external beam therapy and systemically administered radiopharmaceuticals. Patients were followed for at least twelve weeks

    The product Teysuno™ (S-1) contains tegafur, a prodrug of 5-fluorouracil (5-FU), and two modulators of 5-FU metabolism, gimeracil and oteracil. The main clinical study in this application was a randomized controlled study comparing S-1 plus cisplatin with 5-FU plus cisplatin. In this study, median overall survival times of 8.6 months and 7.9 months for S-1 plus cisplatin and 5-FU plus cisplatin, respectively, were observed (hazard ratio, 0.92; 95% confidence interval, 0.80-1.05). The Committee for Medicinal Products for Human Use of the European Medicines Agency concluded that S-1 in combination with cisplatin (75 mg/m²) was noninferior to 5-FU plus cisplatin (100 mg/m²) in patients with advanced gastric cancer and adopted a positive opinion recommending the marketing authorization for this product for the treatment of advanced gastric cancer when given in combination with cisplatin. The recommended dose of S-1 is 25 mg/m² (expressed as tegafur content) twice a day, for 21 consecutive days followed by 7 days rest (one treatment cycle), in combination with 75 mg/m² cisplatin i.v. administered on day 1. This treatment cycle is repeated every 4 weeks. The most common side effects reported in the pivotal study were anemia, neutropenia, vomiting, diarrhea, abdominal pain, weight decrease, anorexia, and fatigue. The objective of this paper is to summarize the scientific review of the application leading to approval in the EU. The full scientific assessment report and the summary of product characteristics are available on the European Medicines Agency website (http://www.ema.europa.eu).

    Endoscopic resection is established in the treatment of early gastric cancer. More advanced gastric cancer requires gastrectomy and D2 lymphadenectomy. Perioperative chemotherapy improves overall survival in locally advanced gastric cancer representing a standard of care. Locally advanced adenocarcinomas of the esophago-gastric junction can alternatively be treated with concurrent radiochemotherapy. In metastatic disease, systemic chemotherapy improves survival, quality of life and symptom control. Trastuzumab plus chemotherapy should be used together with first-line chemotherapy in HER2 positive gastric cancer patients. Second- and third-line therapy is now well established. The anti-VEGFR2 antibody Ramucirumab improves survival in second line treatment both as a monotherapy and in combination with paclitaxel and represents a novel treatment option. © Georg Thieme Verlag KG Stuttgart · New York.

    Gastric surgery is commonly performed to remove foreign bodies and correct gastric dilatation-volvulus and is less commonly performed to treat gastric ulceration or erosion, neoplasia, and benign gastric outflow obstruction. Intestinal surgery, although commonly performed by veterinarians, should never be considered routine. The most common procedures of the small intestinal tract performed in dogs and cats include enterotomy and resection/anastomosis. Surgery of the large intestine is indicated for lesions causing obstruction, perforations, colonic inertia, or chronic inflammation.

    VEGFR-2 has a role in gastric cancer pathogenesis and progression. We assessed whether ramucirumab, a monoclonal antibody VEGFR-2 antagonist, in combination with paclitaxel would increase overall survival in patients previously treated for advanced gastric cancer compared with placebo plus paclitaxel. This randomised, placebo-controlled, double-blind, phase 3 trial was done at 170 centres in 27 countries in North and South America, Europe, Asia, and Australia. Patients aged 18 years or older with advanced gastric or gastro-oesophageal junction adenocarcinoma and disease progression on or within 4 months after first-line chemotherapy (platinum plus fluoropyrimidine with or without an anthracycline) were randomly assigned with a centralised interactive voice or web-response system in a 1:1 ratio to receive ramucirumab 8 mg/kg or placebo intravenously on days 1 and 15, plus paclitaxel 80 mg/m(2) intravenously on days 1, 8, and 15 of a 28-day cycle. A permuted block randomisation, stratified by geographic region, time to progression on first-line therapy, and disease measurability, was used. The primary endpoint was overall survival. Efficacy analysis was by intention to treat, and safety analysis included all patients who received at least one treatment with study drug. This trial is registered with ClinicalTrials.gov, number NCT01170663, and has been completed; patients who are still receiving treatment are in the extension phase. Between Dec 23, 2010, and Sept 23, 2012, 665 patients were randomly assigned to treatment-330 to ramucirumab plus paclitaxel and 335 to placebo plus paclitaxel. Overall survival was significantly longer in the ramucirumab plus paclitaxel group than in the placebo plus paclitaxel group (median 9·6 months [95% CI 8·5-10·8] vs 7·4 months [95% CI 6·3-8·4], hazard ratio 0·807 [95% CI 0·678-0·962]; p=0·017). Grade 3 or higher adverse events that occurred in more than 5% of patients in the ramucirumab plus paclitaxel group versus placebo

    Elective nodal irradiation (ENI) might improve overall survival in patients with inoperable esophageal cancer. We conducted a retrospective analysis to assess the long-term survival and toxicity of esophageal cancer patients treated with ENI versus conventional-field irradiation (CFI). All data in the present study were based on our institutional experience from 2000 to 2005 of patients with inoperable esophageal cancer treated with ENI or CFI plus two concurrent cycles of paclitaxel/cisplatin. Based on the inclusion and exclusion criteria, 89 patients were included in the analysis. Of these patients, 51 were treated with ENI, whereas 38 were treated with CFI. For the per-protocol population, the patients in the ENI group significantly improved in terms of their 10-year disease-specific overall survival (43.1% vs 10.5%, P = 0.019), 10-year disease-free survival (36.7% vs 10.2%, P = 0.040) and 10-year local recurrence-free survival (47.2% vs 17.2%, P = 0.018) compared with the CFI group. Aside from radiation esophagitis, the incidence of grade 3 or greater acute toxicities did not differ between the two groups. Multivariate analysis showed that radiation field, tumor length and clinical stage were independent prognostic factors associated with OS. Concurrent chemoradiotherapy with ENI improves both disease-specific overall survival and loco-regional control in patients with inoperable esophageal cancer receiving per-protocol treatment. The regimen has a manageable tolerability profile. © 2017 The Authors. Cancer Science published by John Wiley & Sons Australia, Ltd on behalf of Japanese Cancer Association.

    Purpose. To analyze the factors associated with favorable survival in patients with inoperable colorectal lung metastases treated with percutaneous image-guided radiofrequency ablation. Methods. Between 2002 and 2011, a total of 398 metastases were ablated in 122 patients (87 male, median age 68 years, range 29-90 years) at 256 procedures. Percutaneous CT-guided cool-tip radiofrequency ablation was performed under sedation/general anesthesia. Maximum tumor size, number of tumors ablated, number of procedures, concurrent/prior liver ablation, previous liver or lung resection, systemic chemotherapy, disease-free interval from primary resection to lung metastasis, and survival from first ablation were recorded prospectively. Kaplan-Meier analysis was performed, and factors were compared by log rank test. Results. The initial number of metastases ablated was 2.3 (range 1-8); the total number was 3.3 (range 1-15). The maximum tumor diameter was 1.7 (range 0.5-4) cm, and the number of procedures was 2 (range 1-10). The major complication rate was 3.9 %. Overall median and 3-year survival rate were 41 months and 57 %. Survival was better in patients with smaller tumors-a median of 51 months, with 3-year survival of 64 % for tumors 2 cm or smaller versus 31 months and 44 % for tumors 2.1-4 cm (p = 0.08). The number of metastases ablated and whether the tumors were unilateral or bilateral did not affect survival. The presence of treated liver metastases, systemic chemotherapy, or prior lung resection did not affect survival. Conclusion. Three-year survival of 57 % in patients with inoperable colorectal lung metastases is better than would be expected with chemotherapy alone. Patients with inoperable but small-volume colorectal lung metastases should be referred for ablation.

    Purpose/Objective: To determine the efficacy of high dose rate (HDR) brachytherapy in patients with medically inoperable endometrial cancer clinically confined to the corpus. Materials and Methods: Forty-two patients with endometrial cancer and an intact uterus have been treated since 1989 with HDR brachytherapy. Twenty-six patients with medically inoperable Stage I disease were treated with radiation alone and form the basis of this study. Obesity was assessed using the body mass index (BMI kg/m{sup 2}) scale. Patients with a BMI above 28 were considered obese and those above 35 morbidly obese, per standard anesthesia guidelines. Brachytherapy was delivered in 5 HDR insertions, 1 week apart, without any external beam radiation. The following doses were delivered per insertion: 5.7 Gy to point S, 7.0 Gy to point W, 8.2 Gy to the vaginal surface and 9.2 Gy to point M. Point M represents the conventional point A dose, while points S and W are myometrial points. A single tandem with either ovoids or cylinders was placed, unless the uterine cavity would accommodate 2 tandems. All treatments were outpatient using intravenous fentanyl and midazolam for sedation. Pelvic ultrasound was commonly used at the time of brachytherapy to verify tandem placement. Three year clinical endpoints were calculated using the Kaplan Meier method. Results: The median follow-up for the study cohort was 21 months with follow-up greater than 36 months in 11 patients. Seventeen of the 26 patients were inoperable due to morbid obesity (median weight and BMI; 316 lbs and 55 kg/m{sup 2}, respectively); the other patients had poor cardiopulmonary reserve {+-} obesity. The median age, KPS (Karnofsky Performance Status), weight, ASA (American Society of Anesthesiologists' Physical Class System) and BMI were 63 yrs, 80%, 285 lbs, 3 and 49 kg/m{sup 2}, respectively. Two patients with an ASA of 3 and 4 died from acute cardio-pulmonary events within 30 days of the last insertion, emphasizing the need

    16 patients under 16 years were irradiated because of inoperable tumours in the central nervous system. Irradiations were performed by cobalt-60 facility and by a Neptun 10-p linear accelerator, and the results were evaluated. In these cases radiotherapy has an important role as it is the only definitive therapeutical intervention. Radiotherapy should be attempted even if the histological verification is impossible and only the clinical course referres to malignant process. Radiotherapy must be carried out on the basis of CT scan controlled irradiation plan. The 3-year survival rate was 14 per cent in the authors' material. (author) 16 refs.; 5 figs.; 3 tabs

    The roentgenographic recognition of gastric varices often is difficult, even when there is a history of liver disease or splenomegaly without demonstrable esophageal varices. An apparant polypoid filling defect with exaggerated mucosal folds in proximal portion of the gastric body and funds on upper GI series, accompanied by hematemesis and splenomegly should suggest the presence of pseudotumoral gastric varices. We have an experience a case of polypoid filling defects in gastric fundus of psudotumoral gastric varices of 49 years old Korean woman, which was diagnosed by surgical and histopathological findings

    Purpose: Liposomal drugs have a better tolerance profile and are highly accumulated in the tumor environment, properties that promise an optimal radiosensitization. We investigated the feasibility of the combination of 5-fluorouracil/lecovorin-based radio-chemotherapy with the administration of high weekly dose of a liposomal platinum formulation (Lipoplatin TM ). Methods and Materials: Lipoplatin was given at a dose of 120mg/m 2 /week, 5-fluorouracil at 400mg/m 2 /week (Day 1), whereas radiotherapy was given through 3.5-Gy fractions on Days 2, 3, and 4. Two groups of 6 patients received four and five consecutive cycles, respectively. Results: Minimal nephrotoxicity (18.2% Grade 1) and neutropenia (9% Grade 3) was noted. Fatigue Grade 2 appeared in 25% of cases. Abdominal discomfort was reported by 18% of patients. No liver, kidney, gastric, or intestinal severe acute or late sequellae were documented, although the median follow-up of 9 months is certainly too low to allow safe conclusions. A net improvement in the performance status (from a median of 1 to 0) was recorded 2 months after the end of therapy. The response rates assessed with computed tomography, endoscopy, and biopsies confirmed 33% (2 of 6) tumor disappearance in patients treated with four cycles, which reached 80% (4 of 5) in patients receiving five cycles. Conclusions: Lipoplatin radio-chemotherapy is feasible, with minor hematological and nonhematological toxicity. The high complete response rates obtained support the testing of Lipoplatin in the adjuvant postoperative or preoperative radio-chemotherapy setting for the treatment of gastric cancer.

    Liposomal drugs have a better tolerance profile and are highly accumulated in the tumor environment, properties that promise an optimal radiosensitization. We investigated the feasibility of the combination of 5-fluorouracil/lecovorin-based radio-chemotherapy with the administration of high weekly dose of a liposomal platinum formulation (Lipoplatin). Lipoplatin was given at a dose of 120 mg/m(2)/week, 5-fluorouracil at 400mg/m(2)/week (Day 1), whereas radiotherapy was given through 3.5-Gy fractions on Days 2, 3, and 4. Two groups of 6 patients received four and five consecutive cycles, respectively. Minimal nephrotoxicity (18.2% Grade 1) and neutropenia (9% Grade 3) was noted. Fatigue Grade 2 appeared in 25% of cases. Abdominal discomfort was reported by 18% of patients. No liver, kidney, gastric, or intestinal severe acute or late sequellae were documented, although the median follow-up of 9 months is certainly too low to allow safe conclusions. A net improvement in the performance status (from a median of 1 to 0) was recorded 2 months after the end of therapy. The response rates assessed with computed tomography, endoscopy, and biopsies confirmed 33% (2 of 6) tumor disappearance in patients treated with four cycles, which reached 80% (4 of 5) in patients receiving five cycles. Lipoplatin radio-chemotherapy is feasible, with minor hematological and nonhematological toxicity. The high complete response rates obtained support the testing of Lipoplatin in the adjuvant postoperative or preoperative radio-chemotherapy setting for the treatment of gastric cancer.

    Gastric cancer is the second leading cause of death from malignant disease worldwide and most frequently discovered in advanced stages. Because curative surgery is regarded as the only option for cure, early detection of resectable gastric cancer is extremely important for good patient outcomes. Therefore, noninvasive diagnostic modalities such as evolutionary endoscopy and positron emission tomography are utilized as screening tools for gastric cancer. To date, early gastric cancer is being treated using minimally invasive methods such as endoscopic treatment and laparoscopic surgery, while in advanced cancer it is necessary to consider multimodality treatment including chemotherapy, radiotherapy, and surgery. Because of the results of large clinical trials, surgery with extended lymphadenectomy could not be recommended as a standard therapy for advanced gastric cancer. Recent clinical trials had shown survival benefits of adjuvant chemotherapy after curative resection compared with surgery alone. In addition, recent advances of molecular targeted agents would play an important role as one of the modalities for advanced gastric cancer. In this review, we summarize the current status of diagnostic technology and treatment for gastric cancer

    Eighty one patients with inoperable non-small cell lung carcinoma (NSCLC) were entered in a randomized phase II trial comparing split-dose irradiation alone to combined treatment radiotherapy and polychemotherapy (C.A.P. + V.D.S.). The quality of life and the survival of the patients were studied. The authors have defined three classes of quality of life responses based on the time elapsed before the performance status index drops. A higher quality of life failure rate was observed in the combined treatment group (p non-significant) but the time elapsed before the Karnofsky index drops is longer in the combined treatment group for the quality of life 'no change' subgroup (p = 0.15). Survival and quality adjusted survival are similar in both treatment groups. The same conclusion holds for retrospective stratified treatment groups. The authors conclude that as far as the quality of life is concerned, polychemotherapy combined with the particular split-dose irradiation schedule used is an effective treatment of inoperable NSCLC.

    The effect of intensive radiotherapy on 1-5 year survival rates of patients with inoperable lung cancer is investigated. Some 123 cases were treated with 200 kV X-rays (> 3500 cGy tumour dose) and 1046 with cobalt-60 ν-rays (> 5000 cGy tumour dose). All patients had inoperable, histologically confirmed tumours, limited to one side of the thorax. Survival rates for 1 year were 22% and 37% respectively; for 3 years 1% and 5%; and for 5 years 0 and 2.5%. In all highly differentiated tumours the authors obtained a 5-year survival with telecobalt therapy of 6.5%, and for all oat-cell cases, 2.5%. By comparing the total result with their own control group of 'untreated', but prognostically more favourable patients (122 thoracotomized cases without resection) the increase of survival rates achieved by Cobalt-60 therapy is convincing (2.5 times for 1 year, 5 times for 2 years). Nevertheless, the very unfavourable prognosis for more than half of the cases justifies trials with systemic therapy. To date chemotherapy does not appear to influence survival times (except for small-cell tumours). Therefore randomized trials with two half-body irradiations (800 cGy each, 'Toronto method') are recommended. (Auth.)

    Full Text Available Although validated predictive factors for breast cancer chemoresistance are scarce, there is emerging evidence that the induction of certain redox-regulating enzymes may contribute to a poor chemotherapy effect. We investigated the possible association between chemoresistance and cellular redox state regulation in patients undergoing neoadjuvant chemotherapy (NACT for breast cancer. In total, 53 women with primarily inoperable or inflammatory breast cancer who were treated with NACT were included in the study. Pre-NACT core needle biopsies and postoperative tumor samples were immunohistochemically stained for nuclear factor erythroid 2-related factor 2 (Nrf2, Kelch-like ECH-associated protein 1 (Keap1, thioredoxin (Trx, and peroxiredoxin I (Prx I. The expression of all studied markers increased during NACT. Higher pre-NACT nuclear Prx I expression predicted smaller size of a resected tumor (p=0.00052; r=−0.550, and higher pre-NACT cytoplasmic Prx I expression predicted a lower amount of evacuated nodal metastasis (p=0.0024; r=−0.472. Pre-NACT nuclear Trx expression and pre-NACT nuclear Keap1 expression had only a minor prognostic significance as separate factors, but when they were combined, low expression for both antibodies before NACT predicted dismal disease-free survival (log-rank p=0.0030. Our results suggest that redox-regulating enzymes may serve as potential prognostic factors in primarily inoperable breast cancer patients.

    Between August 1996 and May 1999, 50 consecutive, previously untreated patients with carcinoma of the esophagus and who were inoperable for various reasons were treated with weekly doses of cisplatin (35 mg/m{sup 2}, maximum 7 cycles) concurrent with either 66 Gy/33 fractions external beam radiotherapy (EBRT) (n=42) or 50 Gy/25 fractions EBRT and two insertions of high-dose-rate intraluminal radiotherapy of 6 Gy each, spaced a week apart (n=8). Eighty-two percent (41/50) of the patients received the stipulated radiotherapy (RT) dose. Seventy-six percent (38/50) received at least 6 cycles of chemotherapy. Neutropenia in the form of WHO grade II-12% (6/50) and grade III-2% (1/50) was observed. Grade III emesis was seen in 8% (4/50). Improvement in the swallowing status was seen in 84% (42/50). Median duration of dysphagia relief was 6 months. The median overall survival was 9 months with 17% estimated to be alive after 4 years. Combined treatment with single agent cisplatin and definitive radiotherapy for inoperable cancer of the esophagus is safe, well tolerated and reasonably efficacious.

    Endoscopic placement of self-expandable metallic stents is reportedly effective for gastric outlet obstructions due to advanced gastric cancer, and is less invasive than gastrojejunostomy. For patients who have good performance status, we administer chemotherapy after stent placement, although the safety and feasibility of this chemotherapy have not yet been discussed in full. Between 2011 and 2015, 15 patients at our institution underwent endoscopic gastroduodenal stent placement for gastric outlet obstruction due to gastric cancer. Eleven of these patients were administered chemotherapy after stent placement. In our case series, we did not observe any specific adverse event caused by stent placement plus chemotherapy. Adverse events after chemotherapy included anemia of CTCAE Grade 3 in 7 patients. Stent-in-stent placement was needed in 2 patients. Neither stent migration nor perforation was observed. Therefore, chemotherapy after stent placement for gastric outlet obstruction due to gastric cancer was considered safe and feasible. Stent placement is useful not only as palliative care for patients with terminal-stage disease, but also as one of the multimodal therapeutic strategies for gastric cancer.

    The estimated volume of meal in the stomach 30 mins after sup(113m)In-DTPA administration was determined in patients with gastric ulcer and normal controls by 1) relating counts in the stomach to those in the whole field of view of the gamma camera and 2) aspirations. In the normal controls there was no significant difference between the two methods but in the gastric ulcer patients, the gamma camera method predicted significantly more meal in the stomach than was recovered by aspiration. It was suggested that the large low lying stomach found in gastric ulcer disease causes extensive overlap of the small bowel and invalidates measurements of gastric emptying made by a gamma camera.

    Although the majority of gastric carcinomas are sporadic, approximately 10% show familial aggregation, and a hereditary cause is determined in 1%-3% cases. Of these, hereditary diffuse gastric cancer is the most recognized predisposition syndrome. Although rare, the less commonly known syndromes also confer a markedly increased risk for development of gastric cancer. Identification and characterization of these syndromes require a multidisciplinary effort involving oncologists, surgeons, genetic counselors, biologists, and pathologists. This article reviews the molecular genetics, clinical and pathologic features, surveillance guidelines, and preventive measures of common and less common hereditary gastric cancer predisposition syndromes. ©AlphaMed Press.

    AIM: To investigate the characteristics of gastric cancer and gastric mucosa in a Mongolian population by comparison with a Japanese population. METHODS: A total of 484 Mongolian patients with gastric cancer were enrolled to study gastric cancer characteristics in Mongolians. In addition, a total of 208 Mongolian and 3205 Japanese consecutive outpatients who underwent endoscopy, had abdominal complaints, no history of gastric operation or Helicobacter pylori eradication treatment, and no use of gastric secretion inhibitors such as histamine H2-receptor antagonists or proton pump inhibitors were enrolled. This study was conducted with the approval of the ethics committees of all hospitals. The triple-site biopsy method was used for the histologic diagnosis of gastritis and H. pylori infection in all Mongolian and Japanese cases. The infection rate of H. pylori and the status of gastric mucosa in H. pylori-infected patients were compared between Mongolian and Japanese subjects. Age (± 5 years), sex, and endoscopic diagnosis were matched between the two countries. RESULTS: Approximately 70% of Mongolian patients with gastric cancer were 50-79 years of age, and approximately half of the cancers were located in the upper part of the stomach. Histologically, 65.7% of early cancers exhibited differentiated adenocarcinoma, whereas 73.9% of advanced cancers displayed undifferentiated adenocarcinoma. The infection rate of H. pylori was higher in Mongolian than Japanese patients (75.9% vs 48.3%, P gastritis changed from antrum-predominant gastritis to corpus-predominant gastritis with age in both populations. CONCLUSION: Gastric cancer was located in the upper part of the stomach in half of the Mongolian patients; Mongolian patients were infected with non-East-Asian-type H. pylori. PMID:26217093

    Full Text Available Abstract Background 18-Fluorodeoxyglucose-PET (18F-FDG-PET can be used for early response assessment in patients with locally advanced adenocarcinomas of the oesophagogastric junction (AEG undergoing neoadjuvant chemotherapy. It has been recently shown in the MUNICON trials that response-guided treatment algorithms based on early changes of the FDG tumor uptake detected by PET are feasible and that they can be implemented into clinical practice. Only 40%-50% of the patients respond metabolically to therapy. As metabolic non-response is known to be associated with a dismal prognosis, metabolic non-responders are increasingly treated with alternative neoadjuvant chemotherapies or chemoradiation in order to improve their clinical outcome. We plan to investigate whether PET can be used as response assessment during radiochemotherapy given as salvage treatment in early metabolic non-responders to standard chemotherapy. Methods/Design The HICON trial is a prospective, non-randomized, explorative imaging study evaluating the value of PET as a predictor of histopathological response in metabolic non-responders. Patients with resectable AEG type I and II according to Siewerts classification, staged cT3/4 and/or cN+ and cM0 by endoscopic ultrasound, spiral CT or MRI and FDG-PET are eligible.

    We evaluated the clinical usefulness of virtual CT gastro endoscopy (VCTGE). The subjects were 124 patients with endoscopically identified gastric lesions. VCTGE images were obtained using a GE-Navigator. We evaluated VCTGE in the visualization of gastric lesions for their presence and morphology. The detection rate of all gastric lesions by VCTGE was 76% (94 of 124 patients). The smallest detectable early gastric cancer was II c measuring 10 x 8 mm. The detection rates of each gastric lesion by VCTGE were 73% in early gastric cancer, and 90% in advanced gastric cancer. VCTGE imaging in the advanced gastric cancer was good in 12 (30%), fair in 25 (60%) and poor in 4 (10%). VCTGE imaging in early gastric cancer was good in 20 (46%), fair in 12 (27%) and poor in 12 (27%). The significance P level was 0.005 between the evaluation of the imaging of advanced and early gastric cancer. VCTGE visualized the characteristics of diverse gastric lesions and was considered useful for the detection and the diagnosis of these lesions. (author)

    Helicobacter pylori is the strongest risk factor for gastric cancer. However, recent advances in DNA sequencing technology have revealed a complex microbial community in the stomach that could also contribute to the development of gastric cancer. The aim of this study was to present recent scientific evidence regarding the role of non-Helicobacter pylori bacteria in gastric carcinogenesis. A systematic review of original articles published in PubMed in the last ten years related to gastric microbiota and gastric cancer in humans was performed. Thirteen original articles were included. The constitution of gastric microbiota appears to be significantly affected by gastric cancer and premalignant lesions. In fact, differences in gastric microbiota have been documented, depending on Helicobacter pylori status and gastric conditions, such as non-atrophic gastritis, intestinal metaplasia and cancer. Gastric carcinogenesis can be associated with an increase in many bacteria (such as Lactobacillus coleohominis, Klebsiella pneumoniae or Acinetobacter baumannii) as well as decrease in others (such as Porphyromonas spp, Neisseria spp, Prevotella pallens or Streptococcus sinensis). However, there is no conclusive data that confirms if these changes in microbiota are a cause or consequence of the process of carcinogenesis. Even though there is limited evidence in humans, microbiota differences between normal individuals, pre-malignant lesions and gastric cancer could suggest a progressive shift in the constitution of gastric microbiota in carcinogenesis, possibly resulting from a complex cross-talk between gastric microbiota and Helicobacter pylori. However, further studies are needed to elucidate the specific role (if any) of different microorganisms.

    Full Text Available BACKGROUND: Early-stage gastric cancer is mostly asymptomatic and can easily be missed easily by conventional gastroscopy. Currently, there are no useful biomarkers for the early detection of gastric cancer, and their identification of biomarkers is urgently needed. METHODS: Gastric juice was obtained from 185 subjects that were divided into three groups: non-neoplastic gastric disease (NGD, advanced gastric cancer and early gastric cancer (EGC. The levels of aromatic amino acids in the gastric juice were quantitated using high-performance liquid chromatography. RESULTS: The median values (25th to 75th percentile of tyrosine, phenylalanine and tryptophan in the gastric juice were 3.8 (1.7-7.5 µg/ml, 5.3 (2.3-9.9 µg/ml and 1.0 (0.4-2.8 µg/ml in NGD; 19.4 (5.8-72.4 µg/ml, 24.6 (11.5-73.7 µg/ml and 8.3 (2.1-28.0 µg/ml in EGC. Higher levels of tyrosine, phenylalanine and tryptophan in the gastric juice were observed in individuals of EGC groups compared those of the NGD group (NGD vs. EGC, P<0.0001. For the detection of EGC, the areas under the receiver operating characteristic curves (AUCs of each biomarker were as follows: tyrosine, 0.790 [95% confidence interval (CI, 0.703-0.877]; phenylalanine, 0.831 (95% CI, 0.750-0.911; and tryptophan, 0.819 (95% CI, 0.739-0.900. The sensitivity and specificity of phenylalanine were 75.5% and 81.4%, respectively, for detection of EGC. A multiple logistic regression analysis showed that high levels of aromatic amino acids in the gastric juice were associated with gastric cancer (adjusted β coefficients ranged from 1.801 to 4.414, P<0.001. CONCLUSION: Increased levels of tyrosine, phenylalanine and tryptophan in the gastric juice samples were detected in the early phase of gastric carcinogenesis. Thus, tyrosine, phenylalanine and tryptophan in gastric juice could be used as biomarkers for the early detection of gastric cancer. A gastric juice analysis is an efficient, economical and convenient method for

    Definitive chemoradiotherapy (dCRT) is standard care for localised inoperable/unresectable oesophageal tumours. Many surgical series have reported on distribution of lymph node metastases (LNM) in resected patients. However, no data is available on the distribution of at-risk LN regions in this more unfavourable patient group. This study aimed to determine the spread of LNM using FDG-PET/CT, to compare it with the distribution in surgical series and to define its impact on the definition of elective LN irradiation (ENI). FDG-PET/CT images of patients with oesophageal cancer treated with dCRT (from 2003 to 2013) were reviewed to identify the anatomic distribution of FDG-avid LNs. Tumours were divided according to proximal, mid-thoracic or distal localisation. About 105 consecutive patients entered analysis. The highest numbers of FDG-avid LNs in proximal tumours were at LN station 101R (45%) and 106recL (35%). For mid-thoracic tumours at 104R (30%) and 105 (30%). For tumours located in the distal oesophagus, the most common sites were along the lesser curvature of the stomach (21%) and the left gastric artery (21%). Except for the supraclavicular and pretracheal nodes, there were no positive locoregional LNM found outside the standard surgical resection area. Our results show a good correlation between the distribution of nodal volumes at risk in surgical series and on FDG-PET/CT. The results can be used to determine target definition in dCRT for oesophageal cancer. For mid-thoracic tumours, the current target delineation guidelines may be extended based on the risk of node involvement, but more clinical studies are needed to determine if the potential harm of expanding the CTV outweighs the potential benefit.

    Definitive chemoradiotherapy (dCRT) is standard care for localised inoperable/unresectable oesophageal tumours. Many surgical series have reported on distribution of lymph node metastases (LNM) in resected patients. However, no data is available on the distribution of at-risk LN regions in this more unfavourable patient group. This study aimed to determine the spread of LNM using FDG-PET/CT, to compare it with the distribution in surgical series and to define its impact on the definition of elective LN irradiation (ENI). FDG-PET/CT images of patients with oesophageal cancer treated with dCRT (from 2003 to 2013) were reviewed to identify the anatomic distribution of FDG-avid LNs.

    Full Text Available Malignant pheochromocytoma (PCC is a rare condition. Although the liver is the second most frequent site of metastasis in malignant PCC, no definite treatments have been established. Herein, we report a case of liver metastasis of PCC that was successfully treated by transcatheter arterial chemoembolization (TACE. A 69-year-old man was admitted to the Department of Gastroenterology for evaluation of an incidental hepatic mass in August 2013. He had undergone right adrenalectomy in May 2005 and PCC had been confirmed on the basis of histopathological findings. Liver biopsy was performed, and metastatic PCC was diagnosed. The lesion appeared inoperable because of invasion of the portal vein and metastases in the lymph nodes along the hepatoduodenal ligament. Thus, TACE was performed instead. After TACE, symptoms including dizziness and cold sweating improved, and the patient's serum catecholamine levels decreased. On the basis of this case, we believe that TACE may be a useful treatment for liver metastasis in malignant PCC.

    Transrectal sonography is helpful in the classification of parametrial infiltration prior to treatment as well as in the follow-up. In this study, we performed rectal sonography in cases of inoperable cervical cancer to objectify the reduction of the infiltration of the uterine cervix and of the parametrium. Rectosonography was performed in 10 patients with histologically confirmed cancer of the uterine cervix before and after radiation treatment. The patients were treated with brachytherapy and teletherapy with an average radiation dose of 7680 rad. The whole therapy was finished after 6 to 9 weeks. Rectosonography enabled us to objectify the effect of radiation therapy. The length and width of parametrial infiltration could be measured in relation to the pelvis wall. Furthermore, the configuration of the parametrium could be imaged. Therefore, in cervical cancer, rectosonography is a valuable method to check and the documentate the effect of treatment and to diagnose recurrency. (orig.) [de

    1982-01-01

    131 patients with lung, esophagus, rectum and mandibulofacial tumors, most of them being inoperable, were treated with fractionated gamma teletherapy. The daily focus dose of 2-2.2 Gy was applied in 2 fractions with an interval of 4-6 h. The total focus dose of one course of treatment was 40-70 Gy. In 56 patients (42.7%) a complete regression of the tumors and of the increased regional lymph nodes was obtained. The irradiation by the mentioned technique showed the highest effectivity for tumors of the lung and the esophagus. The diminished frequency and an easier progress of the radiation reactions are important because they often prevent to carry out a radical therapy. (author)

    The patient, a 65-year-old male with far advanced gastric cancer of H3N4 (Stage 4), was assumed inoperable on admission and chemotherapy using CDDP, MMC and UFT(PMU) was carried out. As a result, the levels of AFP and CEA were reduced notably, and PR effects were recognized in liver and lymphnode metastatic lesion. Thus, 2 months later, reduction surgery was performed, during which primary lesion was resected and a reservoir tube for chemotherapy was placed in the common hepatic artery. Subsequently, the chemotherapy with Etoposide added to PMU(PMUE) was continued by utilization of a reservoir, so that liver metastasis decreased more than 90% from the maximum. However, metastasis lesions of left lobe of the liver had enlarged with reincrease of AFP and CEA since 6 months after the operation. A month later left lobectomy of the liver was performed. Residual metastases of the liver were then enlarged. PMUE with Ca antagonist was used with little effect then. The patient died of liver failure 15 months after initial admission.

    Purpose: To describe efficacy and safety of stereotactic body radiation therapy (SBRT) for the treatment of inoperable hepatocellular carcinoma. Methods: The records of 77 consecutive patients treated with SBRT for 97 liver-confined HCC were reviewed. A total dose of 45 Gy in 3 fractions was prescribed to the 80% isodose line. Local control (LC), overall survival (OS), progression-free survival (PFS) and toxicity were studied. Results: The median follow-up was 12 months. The median tumor diameter was 2.4 cm. The LC rate was 99% at 1 and 2 years. The 1 and 2-year OS were 81.8% and 56.6% respectively. The median time to progression was 9 months (0–38). The rate of hepatic toxicity was 7.7% [1.6–13.7], 14.9% [5.7–23.2] and 23.1% [9.9–34.3] at 6 months, 1 year and 2 years respectively. In multivariate analysis, female gender (HR 7.87 [3.14–19.69]), a BCLC B-C stage (HR 3.71 [1.41–9.76]), a sum of all lesion diameters ⩾2 cm (HR 7.48 [2.09–26.83]) and a previous treatment (HR 0.10 [0.01–0.79]) were independent prognostic factors of overall survival. Conclusion: SBRT allows high local control for inoperable hepatocellular carcinomas. It should be considered when an ablative treatment is indicated in Child A patients

    The purpose of this study was to assess the clinical outcomes of hypofractionated radiotherapy (HFRT) with three-dimensional conformal technique for medically inoperable patients with early stage non-small-cell lung cancer (NSCLC) and to evaluate prognostic factors. We performed a retrospective review of 26 patients who underwent HFRT for early stage NSCLC between September 2005 and August 2011. Only clinical stage T1-3N0 was included. The median RT dose was 70 Gy (range, 60 to 72 Gy) and the median biologically equivalent dose (BED) was 94.5 Gy (range, 78.0 to 100.8 Gy). In 84.6% of patients, 4 Gy per fraction was used. Neoadjuvant chemotherapy with paclitaxel and cisplatin was given to 2 of 26 patients. The median follow-up time for surviving patients was 21 months (range, 13 to 49 months). The overall response rate was 53.9%, and the initial local control rate was 100%. The median survival duration was 27.8 months. Rates of 2-year overall survival, progression-free survival (PFS), local control (LC), and locoregional-free survival (LRFS) were 54.3%, 61.1%, 74.6%, and 61.9%, respectively. Multivariate analysis showed that BED (>90 vs. {<=}90 Gy) was an independent prognostic factor influencing PFS, LC, and LRFS. Severe toxicities over grade 3 were not observed. Radical HFRT can yield satisfactory disease control with acceptable rates of toxicities in medically inoperable patients with early stage NSCLC. HFRT is a viable alternative for clinics and patients ineligible for stereotactic ablative radiotherapy. BED over 90 Gy and 4 Gy per fraction might be appropriate for HFRT.

    2013-02-15

    To characterize Borrmann type IV from Borrmann type III advanced gastric cancer (AGC) by two-phased multi-detector row computed tomography (MDCT) using the water filling method. A total of 143 patients (pathologically confirmed Borrmann type III and IV - 100 and 43 patients), who underwent preoperative MDCT, were enrolled. Two radiologists, retrospectively and independently, determined tumor enhancement pattern using a 5-grade scale without clinical information. A weighted kappa test was applied for interobserver variability. The score of tumor enhancement pattern correlated with Borrmann type as determined by Spearman's correlation coefficient. The accuracy of differentiation of Borrmann type using MDCT was determined by receiver operating characteristic curves. Interobserver agreement (weighted kappa = 0.683) was substantial. The tumor enhancement pattern score showed a significant correlation with Borrmann type (reviewer 1, r = 0.591, p < 0.001; reviewer 2, r = 0.616, p < 0.001). The accuracy for differentiation of Borrmann type on MDCT was 0.86 (p < 0.001) in both reviewers. The sensitivity and specificity of the diagnosis of Borrmann type IV were 79% and 82% in reviewer 1, and 88% and 78% in reviewer 2, respectively. Dual-phased MDCT using the water filling method can differentiate between Borrmann type IV and III AGC with high accuracy.

    The choice of chemotherapy in HER2-negative gastric cancer is based on centre's preferences and adverse effects profile. No schedule is currently accepted as standard, nor are there any factors to predict response, other than HER2 status. We seek to evaluate whether Lauren type influences the efficacy of various chemotherapies and on patient overall survival (OS). We have conducted a multicenter study in 31 hospitals. The eligibility criteria include diagnosis of stomach or gastroesophageal junction adenocarcinoma, HER2 negativity, and chemotherapy containing 2-3 drugs. Cox proportional hazards regression adjusted for confounding factors, with tests of 'treatment-by-histology' interaction, was used to estimate treatment effect. Our registry contains 1303 tumours analysable for OS end points and 730 evaluable for overall response rate (ORR). A decrease in ORR was detected in the presence of a diffuse component: odds ratio 0.719 (95% confidence interval (CI), 0.525-0.987), P=0.039. Anthracycline- or docetaxel-containing schedules increased ORR only in the intestinal type. The diffuse type displayed increased mortality with hazard ratio (HR) of 1.201 (95% CI, 1.054-1.368), P=0.0056. Patients receiving chemotherapy with docetaxel exhibited increased OS limited to the intestinal type: HR 0.65 (95% CI, 0.49-0.87), P=0.024, with no increment in OS for the subset having a diffuse component. With respect to progression-free survival (PFS), a significant interaction was seen in the effect of docetaxel-containing schedules, with better PFS limited to the intestinal type subgroup, in the comparison against any other schedule: HR 0.65 (95% CI, 0.50-0.85), P=0.015, and against anthracycline-based regimens: HR 0.64 (95% CI, 0.46-0.88), P=0.046. As a conclusion, in this registry, Lauren classification tumour subtypes predicted survival and responded differently to chemotherapy. Future clinical trials should stratify effect estimations based on histology.

    The gastric lesion is a common source of complaints to Orientals, however, evaluation of gastric symptoms and laboratory examination offer little specific aid in the diagnosis of gastric diseases. Thus roentgenography of gastrointestinal tract is one of the most reliable method for detail diagnosis. On double contract study of stomach, gastric filling defect is mostly caused by malignant gastric cancer, however, other benign lesions can cause similar pictures which can be successfully treated by surgery. 66 cases of benign causes of gastric filling defect were analyzed at this point of view, which was verified pathologically by endoscope or surgery during recent 7 years in Yensei University College of Medicine, Severance Hospital. The characteristic radiological picture of each disease was discussed for precise radiologic diagnosis. 1. Of total 66 cases, there were 52 cases of benign gastric tumor 10 cases of gastric varices, 5 cases of gastric bezoar, 5 cases of corrosive gastritis, 3 cases of granulomatous disease and one case of gastric hematoma. 2. The most frequent causes of benign tumors were adenomatous polyp (35/42) and the next was leiomyoma (4/42). Others were one of case of carcinoid, neurofibroma and cyst. 3. Characteristic of benign adenomatous polyp were relatively small in size, smooth surface and were observed that large size, benign polyp was frequently type IV lesion with a stalk. 4. Submucosal tumors such as leiomyoma needed differential diagnosis with polypoid malignant cancer. However, the characteristic points of differentiation was well circumscribed smooth margined filling defect without definite mucosal destruction on surface. 5. Gastric varices showed multiple lobulated filling defected especially on gastric fundus that changed its size and shape by respiration and posture of patients. Same varices lesions on esophagus and history of liver disease were helpful for easier diagnosis. 6. Gastric bezoar showed well defined movable mass

    The aim of this study was to evaluate the efficacy and complications of self-expandable metallic stent placement for patients with inoperable esophageal carcinoma after radiotherapy and/or chemotherapy. We obtained data from 19 patients with advanced or recurrent esophageal carcinoma between 1996 and 2000. In all patients, a self-expandable metallic stent was placed under fluoroscopic guidance. Dysphagia before and after stent placement was graded. Complications after stent placement were also evaluated. Data were compared between patients with and without prior radiotherapy and/or chemotherapy. The procedure was technically successful in all but one patient. The dysphagia grade improved in all patients. No life-threatening complications occurred. The other major complications such as mediastinitis occurred in two patients, and pneumonia and funnel phenomenon occurred in one patient each. These patients had a history of radiotherapy and/or chemotherapy prior to stent placement. Eight of the twelve patients with prior radiotherapy and/or chemotherapy compared with one of seven patients without prior therapy had persistent chest pain, which was a statistically significant difference (P<0.05). Placement of self-expandable metallic stents was effective for patients with advanced or recurrent esophageal carcinoma. However, prior irradiation and/or chemotherapy increased the risk of persistent chest pain after stent placement. (author)

    Full Text Available Background. Shape modification has been one of the methods adopted to improve stent patency but has not always translated into positive outcome. The aim of this study was to compare the efficacy of shape-modified partially covered self-expandable metal stent (SEMS that has enlarged head versus uncovered SEMS for palliation of gastric outlet obstruction (GOO. Methods. A total of 48 patients underwent insertion of either enlarged-head SEMS (n=24 or uncovered SEMS (uSEMS (n=24 for palliation of GOO from July 2009 to July 2016. Patients with inoperable or advanced malignancy were included. Technical feasibility and clinical outcomes were compared. Results. Technical success rate was 100% (24/24 and 95.8% (23/24 for enlarged-head SEMS group and uSEMS group, respectively. Clinical success rate was 87.5% (21/24 and 87.0% (20/23 for enlarged-head SEMS group and uSEMS group, respectively. The gastric outlet obstruction scoring system score significantly improved in both groups (p<0.001 for both. Mean survival was similar between the groups: enlarged-head SEMS group, 99.3 days (range, 19–358 days versus uSEMS group, 82.1 days (range, 11–231 days (p=0.418. The mean stent patency also showed no difference between the groups: enlarged-head SEMS group, 87.1 days (range, 8–358 days versus uSEMS group, 60.4 days (range, 2–231 days (p=0.204. With enlarged-head SEMS, distal migration did not occur, but proximal migration was observed in four cases. Conclusions. Distal migration was prevented by shaping the SEMS to have an enlarged head, but improvement in stent patency could not be observed.

    Recently, studies have reported that protein glycosylation plays an important role in the occurrence and development of cancer. Gastric cancer is a common cancer with high morbidity and mortality owing to most gastric cancers are discovered only at an advanced stage. Here, we aim to discover novel specific serum glycanbased biomarkers for gastric cancer. A lectin microarray with 50 kinds of tumor-associated lectin was used to detect the glycan profiles of serum samples between early gastric cancer and healthy controls. Then lectin blot was performed to validate the differences. The result of the lectin microarray showed that the signal intensities of 13 lectins showed significant differences between the healthy controls and early gastric cancer. Compared to the healthy, the normalized fluorescent intensities of the lectins PWA, LEL, and STL were significantly increased, and it implied that their specifically recognized GlcNAc showed an especially elevated expression in early gastric cancer. Moreover, the binding affinity of the lectins EEL, RCA-II, RCA-I, VAL, DSA, PHA-L, UEA, and CAL were higher in the early gastric cancer than in healthy controls. These glycan structures containing GalNAc, terminal Galβ 1-4 GlcNAc, Tri/tetraantennary N-glycan, β-1, 6GlcNAc branching structure, α-linked fucose residues, and Tn antigen were elevated in gastric cancer. While the two lectins CFL GNL reduced their binding ability. In addition, their specifically recognized N-acetyl-D-galactosamine structure and (α-1,3) mannose residues were decreased in early gastric cancer. Furthermore, lectin blot results of LEL, STL, PHA-L, RCA-I were consistent with the results of the lectin microarray. The findings of our study clarify the specific alterations for glycosylation during the pathogenesis of gastric cancer. The specific high expression of GlcNAc structure may act as a potential early diagnostic marker for gastric cancer.

    Patients with early gastric cancers that are limited to gastric mucosa or submucosa usually have an advanced loss of mucosal glandular tissue (glandular atrophy) and are at high risk for subsequent (metachronous) development of new gastric cancer. The long-term effects of treatment to eradicate Helicobacter pylori on histologic improvement and the prevention of metachronous gastric cancer remain unclear. In this prospective, double-blind, placebo-controlled, randomized trial, we assigned 470 patients who had undergone endoscopic resection of early gastric cancer or high-grade adenoma to receive either H. pylori eradication therapy with antibiotics or placebo. Two primary outcomes were the incidence of metachronous gastric cancer detected on endoscopy performed at the 1-year follow-up or later and improvement from baseline in the grade of glandular atrophy in the gastric corpus lesser curvature at the 3-year follow-up. A total of 396 patients were included in the modified intention-to-treat analysis population (194 in the treatment group and 202 in placebo group). During a median follow-up of 5.9 years, metachronous gastric cancer developed in 14 patients (7.2%) in the treatment group and in 27 patients (13.4%) in the placebo group (hazard ratio in the treatment group, 0.50; 95% confidence interval, 0.26 to 0.94; P=0.03). Among the 327 patients in the subgroup that underwent histologic analysis, improvement from baseline in the atrophy grade at the gastric corpus lesser curvature was observed in 48.4% of the patients in the treatment group and in 15.0% of those in the placebo group (Pgastric cancer who received H. pylori treatment had lower rates of metachronous gastric cancer and more improvement from baseline in the grade of gastric corpus atrophy than patients who received placebo.

    Highlights: • Leptin and Ob-R are expressed in gastric adenoma and early and advanced cancer. • Leptin is more likely associated with differentiated gastric cancer or cardia cancer. • Leptin proliferates gastric cancer cells via activating the STAT3 and ERK1/2 pathways. - Abstract: Obesity is associated with certain types of cancer, including gastric cancer. However, it is still unclear whether obesity-related cytokine, leptin, is implicated in gastric cancer. Therefore, we aimed to investigate the role of leptin in gastric cancer. The expression of leptin and its receptor, Ob-R, was assessed by immunohistochemical staining and was compared in patients with gastric adenoma (n = 38), early gastric cancer (EGC) (n = 38), and advanced gastric cancer (AGC) (n = 38), as a function of their clinicopathological characteristics. Gastric cancer cell lines were studied to investigate the effects of leptin on the signal transducer and activator of transcription-3 (STAT3) and extracellular receptor kinase 1/2 (ERK1/2) signaling pathways using MTT assays, immunoblotting, and inhibition studies. Leptin was expressed in gastric adenomas (42.1%), EGCs (47.4%), and AGCs (43.4%). Ob-R expression tended to increase from gastric adenoma (2%), through EGC (8%), to AGC (18%). Leptin induced the proliferation of gastric cancer cells by activating STAT3 and ERK1/2 and up-regulating the expression of vascular endothelial growth factor (VEGF). Blocking Ob-R with pharmacological inhibitors and by RNAi decreased both the leptin-induced activation of STAT3 and ERK1/2 and the leptin-induced expression of VEGF. Leptin plays a role in gastric cancer by stimulating the proliferation of gastric cancer cells via activating the STAT3 and ERK1/2 pathways

    Weight loss following gastroplasty had no correlation with gastric emptying rate. Patients who showed transient prolongation of gastric emptying returned to normal one year later and showed no significant difference in weight loss from those who did not have temporary delayed gastric emptying. Perhaps gatroplasty (at least temporarily) reduces the gastric volume producing early satiation without affecting the gastric emptying rate as tested by a small volume radiolabelled test meal. Longer follow-up is indicated to see if delayed weight gain occurs because of gastric pouch stretching and if this has any correlation with gastric emptying rate. (Author)

    We have studied bone scintigrams in 60 patients with gastric cancer. Of these 60 patients, bone metastases were found in 15 patients (25 %). There were no evidence of bone metastases in polypoid lesions, cancers of the antrum, carcinomas in situ, advanced cancers without invasion to serosa, cancer with N 0 or N 1 regional lymph node metastases, highly deferenciated adenocarcinomas and papillary adenocarcinomas. On the contrary, high rates of bone metastases were seen in cancers of the corpus, advanced cancers with invasion to neighbouring structures and tubular adenocarcinomas. Of these 15 patients with bone metastasis, 3 patients showed very similar clinical features and the findings of ''diffuse bone metastases on bone scintigrams.'' Cancer of the antrum showed high rates of liver metastases, while cancers of the corpus showed high rates of bone stastases. Sixty percent of the patients with bone metastases did not have liver metastases and there seemed to be no significant relationship between liver metastases and bone metastases. From these results we suppose that non-portal tract through the vertebral venous plexus instead of portal tract may be the other route of bone metastases from gastric cancer. (author)

    Laparoscopic technology is gradually accepted in gastric cancer surgery, whose efficacy has been demonstrated by some clinical researches. Randomized controlled trials (RCT) are considered as the most important evidence to prove clinical outcomes of laparoscopic surgery for gastric cancer. Korean gastric surgeons have made great contributions to RCT in laparoscopic gastric cancer surgery. KLASS (Korean Laparoscopic Gastrointestinal Surgery Study Group) is one of the most important forerunner and global leader of clinical trials of gastric cancer treatment. KLASS series clinical trials are attracting global attention because of the significant value of surgical treatment for gastric cancer. The RCTs in Korea involve in many aspects of laparoscopic gastrectomy for gastric cancer, including laparoscopy application in early gastric cancer (KLASS-01, KLASS-03 and KLASS-07), advanced gastric cancer (KLASS-02 and KLASS-06), function-preserving gastrectomy (KLASS-04,KLASS-05) and sentinel node navigation surgery (SENORITA trial). In order to share some informations of these RCTs, we review and prospect some important clinical trials of laparoscopic gastric cancer surgery in Korea. With the experience of Korean gastric surgeons, we can make more progress in our own clinical trials of laparoscopic gastric cancer surgery.

    Helicobacter pylori has generated public health interest since its identification in 1983. Past studies have suggested that the bacterium plays a role in the pathogenesis of gastric cancer. More recent studies support the conclusion that the association of H. pylori with gastric cancer is causal. The purpose of this article is to review the available evidence supporting the association of H. pylori with gastric cancer. We performed a critical review of the relevant literature published in the English language on H. pylori and gastric cancer using MEDLINE, Index Medicus for the years 1985 to 1997. The reference lists of selected articles also were reviewed to capture citations for further pertinent studies. H. pylori is thought to be the major cause of chronic atrophic gastritis. H. pylori gastritis is worldwide in distribution. H. pylori is now categorized by the International Agency for Cancer Research as a group 1 carcinogen, i.e., an agent that is carcinogenic to humans. Several reports from the United States have found the highest frequencies of gastric cancer in geographic areas and populations with the highest rates of acquisition of H. pylori infection. The high prevalence of H. pylori infection has been documented most notably in blacks and Hispanics, who also are at high risk for gastric cancer. New studies that focus on the epidemiology and pathology of H. pylori improve our understanding of its relationship with gastric cancer and advance the development of gastric cancer prevention and control strategies that are proposed.

    Mechanisms regulating gastric emptying have been characterized through many decades of experimental work. Both central and peripheral mechanisms are important. Central mechanisms are related to the center of vomiting and are probably influenced by psychologic and emotional factors. Peripheral mechanisms are located at both sides of the pylorus. Gastric mechanisms are stimulatory and are triggered mainly by distention of the stomach, although hormonal mechanisms may also participate (gastrin). However, with complex, nutrient-containing meals, the intragastric volume is not the primary determinant of gastric emptying. Inhibitory mechanisms of the gut are more important. The key factors are the pH, osmolality, and nutrient content of the chyme being emptied into the duodenum. Osmotic and pH-sensitive receptors are thought to reside in the duodenum. On the other hand, receptors triggered by nutrients extend much more distally into the duodenum and are sensitive to nutrient composition and load. Protein, carbohydrates, and lipids all inhibit gastric emptying, although the lipids are probably the most potent inhibitors. If the duodenal load or the characteristics of the emptying material are not adequate, inhibitory mechanisms will reduce gastric emptying at the expense of expanding the intragastric volume. It is therefore not possible to dissociate postprandial gastric emptying from postprandial gastric secretion

    More than 50% of patients with esophageal cancer already have inoperable disease at the time of diagnosis. Controversy surrounds the outcomes of patients with advanced esophageal cancer who receive palliative care by either stent alone or stent plus an additional modality. We set out to perform a systematic review and meta-analysis of studies assessing the use of metal stents as treatment options for symptomatic improvement, survival, and adverse events. We searched Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception until January 14, 2016, as well as other databases for randomized controlled trials (RCTs) comparing esophageal stent versus either esophageal stent plus brachytherapy, radiotherapy, or chemotherapy. For quality assurance purposes throughout the systematic review, multiple independent extractions were performed, and the process was executed as per the standards of the Cochrane collaboration. Primary outcomes were mean change in dysphagia score, overall survival, and quality of life. Secondary outcomes were adverse events including fever, severe pain, aspiration, fistula, stent migration, perforation, and restenosis. Eight RCTs enrolling 732 patients were included with three distinct comparisons: stents combination therapy vs stents alone (5 studies, n = 417), stents alone versus brachytherapy alone (2 studies, n = 274), and stents + brachytherapy vs brachytherapy alone (1 study, n = 41). Stents combination therapy was defined as stents plus radiotherapy, chemotherapy, or both. Mean change in dysphagia scores favored stents combination therapy versus stents alone, and the effect was seen in patients surviving longer than 3 months. Stents combination therapy was also associated with a more favorable overall survival. The risks of stent migration, aspiration pneumonia, and restenosis were lower in the stents combination group compared to stents alone, while the risks of severe pain, hemorrhage, and

    We previously studied a dose-dense TCF (TCF-dd) regimen demonstrating its feasibility and an activity comparable to epirubicin-based chemotherapy and TCF q3w in terms of overall survival and time to progression (TTP). We report here the final results of a phase II study of chemotherapy with a modified TCF-dd regimen in locally advanced or metastatic gastric cancer (MGC). Patients with histologically confirmed measurable MGC, not previously treated for advanced disease, received docetaxel 70 mg/m(2) day 1, cisplatin 60 mg/m(2) day 1, l-folinic acid 100 mg/m(2) days 1 and 2, followed by 5-fluorouracil (5-FU) 400 mg/m(2) bolus days 1 and 2, and then 600 mg/m(2) as a 22-h continuous infusion days 1 and 2, every 14 days, plus pegfilgrastim 6 mg on day 3. Patients aged ≥65 years received the same schedule with a dose reduction of 30 %. Study duration: December 2007-November 2010. Forty-six consecutive patients were enrolled (78 % male, 22 % female; median age, 66 years, range, 38-76 years; ECOG PS: 0, 48 %, 1, 46 %). Primary endpoint was overall response rate (ORR). A median of four cycles (range, one to six) was administered. Forty-three patients were evaluated for response (93.5 %) and all for toxicity: 3 complete response (CR), 25 partial response (PR), 10 stable disease (SD), and 5 progressive disease (PD) were observed, for an ORR by intention to treat (ITT) of 61 % (95 % CI 47-75). Median overall survival (OS) was 17.63 months (95 % CI, 13.67-20.67); median progression-free survival was 8.9 months (95 % CI, 6.5-13.4). Twenty-one patients (46.0 %) were treated at full doses without any delay, thus respecting the dose-dense criterion. Most frequent grade 3-4 toxicities were neutropenia (20 %), leukopenia (4 %), thrombocytopenia (2 %), anemia (2 %), febrile neutropenia (6 %), asthenia (22 %), diarrhea (4 %), nausea/vomiting (11 %), and hypokalemia (6 %). Overall, TCF-dd was shown to be safe. The TCF-dd regimen in locally advanced or MGC

    The aim of this work was to evaluate the clinical efficacy and safety of simultaneous integrated boost-intensity modulated radiation therapy (SIB-IMRT) in patients with inoperable hepatocellular carcinoma (HCC). A total of 53 patients with inoperable HCC underwent SIB-IMRT using two dose-fractionation schemes, depending on the proximity of gastrointestinal structures. The 41 patients in the low dose-fractionation (LD) group, with internal target volume (ITV) < 1 cm from gastrointestinal structures, received total doses of 55 and 44 Gy in 22 fractions to planning target volume 1 (PTV1) and 2 (PTV2), respectively. The 12 patients in the high dose-fractionation (HD) group, with ITV ≥ 1 cm from gastrointestinal structures, received total doses of 66 and 55 Gy in 22 fractions to the PTV1 and PTV2, respectively. Overall, treatment was well tolerated, with no grade > 3 toxicity. The LD group had larger sized tumors (median: 6 vs. 3.4 cm) and greater frequencies of vascular invasion (80.6 vs. 16.7 %) than patients in the HD group (p < 0.05 each). The median overall survival (OS) was 25.1 months and the actuarial 2-year local progression-free survival (LPFS), relapse-free survival (RFS), and OS rates were 67.3, 14.7, and 54.7 %, respectively. The HD group tended to show better tumor response (100 vs. 62.2 %, p = 0.039) and 2-year LPFS (85.7 vs. 59 %, p = 0.119), RFS (38.1 vs. 7.3 %, p = 0.063), and OS (83.3 vs. 44.3 %, p = 0.037) rates than the LD group. Multivariate analysis showed that tumor response was significantly associated with OS. SIB-IMRT is feasible and safe for patients with inoperable HCC. (orig.)

    EDF operates 58 Pressurized Water Reactors in France. In the mid 2000‟s some of them have been affected by Steam Generators (SG) Tube Support Plates (TSP) blockage and U-tubes external surface fouling with iron oxides deposits due to corrosion of secondary-side components. These issues have been tackled by a global maintenance strategy of chemical cleanings and a method for in-operation monitoring of fouling and TSP blockage has been developed and is implemented since mid 2009. This monitoring is aimed at giving information for SG maintenance planning as regards non destructive examinations and chemical cleaning. This paper will first remind of the physical reasons of fouling and TSP blockage and identify the resulting stakes regarding safety and availability along with the action levers available to control both phenomena. Then details will be given on how in-operation monitoring of fouling and TSP blockage is carried out, using measurements of Wide Range water Level (WRL) and SG steam pressure during thermally stabilized periods. Information will also be given on how those data are analyzed and shared as well at a local as at a corporate level to participate in the planning of SG inspection and maintenance operations. Finally, possible refinements will be discussed, notably regarding the issue of WRL measurements reliability and the possibility to use the analysis of SG dynamic behavior during power transients to assess the TSP blockage ratio. In terms of „issues requiring discussion‟, the following are operational issues currently being investigated by EDF: 1. SG pressure can have quite large variations during one operating cycle (notably after a plant trip) and from one cycle to the other and generally pressure tends to decrease on a long-term basis. How can such variations be explained? What are the solutions to moderate/stop the pressure loss? 2. On some of the SG-models operated by EDF, hard curative Chemical Cleaning of the U-tubes didn't bring

    Introduction: The purpose of this study was to compare the results of medium dose rate (MDR) intraluminal brachytherapy (ILBT) and high dose rate (HDR) ILBT in patients with inoperable esophageal carcinoma, with regard to dysphagia, complication rate and survival. Material and methods: Included were 114 patients with inoperable esophageal cancer who were treated with a single session of ILBT. In all cases a single dose of 15 Gy was administered, calculated at a 1 cm radius. Forty-eight patients were treated with MDR ( 137 Cs)ILBT. In June 1990 MDR was replaced by HDR and from then 66 patients were treated with HDR ( 192 Ir). Dysphagia was prospectively scored using a 5-point scale at 6 weeks, 3, 6, 9 and 12 months. Results: No significant differences were noted between the two groups with regard to pretreatment variables. In patients treated with MDR-ILBT improvement of swallowing ability was noted in 30 out of 42 evaluable patients (71%), no change in 9 (21%) and progression of dysphagia in 3 patients (8%), as compared to 34 out of 59 evaluable patients (58%), 16 (27%) and 6 (15%) resp. in de HDR-ILBT group. In the latter category, progression of dysphagia was caused by fistulae in 2 patients. The differences were not significant (ns). Additional treatment in case of recurrent or persistent dysphagia was needed in 50% of the cases in the MDR-ILBT group as compared to 41% in the HDR-ILBT group (ns). The median survival of the MDR-ILBT group was 3.9 months as compared to 4.3 months in the HDR-ILBT group (ns). In 2 patients (4%) treated with MDR-ILBT bronchio-oesphageal fistulae developed at 6 weeks and 2 months. In the HDR-ILBT group fistulae were noted in 7 cases (11%) at 2 weeks, 4 weeks, 2, 3, 3, 4 and 9 months (ns). In all of these cases persistent of recurrent tumour was present. Conclusions: No significant differences were noted with regard to palliation of dysphagia, survival and complication rate between MDR-ILBT and HDR-ILBT in the management of esophageal

    The combination of a fluoropyrimidine [5-fluorouracil (5-FU), capecitabine, or S-1] with a platinum analog (cisplatin or oxaliplatin) is the most widely accepted first-line chemotherapy regimen for metastatic or recurrent advanced gastric cancer (AGC), based on the results of clinical trials. However, there is little evidence to guide chemotherapy for elderly patients with AGC because of under-representation of this age group in clinical trials. Thus, the aim of this study is to determine the optimal chemotherapy regimen for elderly patients with AGC by comparing the efficacies and safeties of combination therapy versus monotherapy as first-line chemotherapy. This study is a randomized, controlled, multicenter, phase III trial. A total of 246 elderly patients (≥70 years old) with metastatic or recurrent AGC who have not received previous palliative chemotherapy will be randomly allocated to a combination therapy group or a monotherapy group. Patients randomized to the combination therapy group will receive fluoropyrimidine plus platinum combination chemotherapy (capecitabine/cisplatin, S-1/cisplatin, capecitabine/oxaliplatin, or 5-FU/oxaliplatin), and those randomized to the monotherapy group will receive fluoropyrimidine monotherapy (capecitabine, S-1, or 5-FU). The primary outcome is the overall survival of patients in each treatment group. The secondary outcomes include progression-free survival, response rate, quality of life, and safety. We are conducting this pragmatic trial to determine whether elderly patients with AGC will obtain the same benefit from chemotherapy as younger patients. We expect that this study will help guide decision-making for the optimal treatment of elderly patients with AGC.

    Individuals infected with Helicobacter pylori, a stomach colonizing bacteria, have an increased risk of developing gastric malignancies. The risk for developing cancer relates to the physiologic and histologic changes that H. pylori infection induces in the stomach. In the last year numerous studies have been conducted in order to characterize the association between H. pylori infection and gastric cancer. These studies range from epidemiologic approaches aiming at the identification of envir...

    BACKGROUND: High levels of intact and cleaved forms of the urokinase-type plasminogen activator receptor (uPAR) in both tissue and blood are associated with poor survival in several cancer diseases. The prognostic significance of uPAR in cholangiocarcinoma is unknown. The aims of this study were...... to determine if pre-treatment serum levels of uPAR forms and a decrease in levels during chemotherapy are predictive of survival in patients with inoperable cholangiocarcinoma. DESIGN AND METHODS: Patients with inoperable cholangiocarcinoma were consecutively included in the training set (n=108). A test set......PAR(I-III)+uPAR(II-III) after 2cycles of chemotherapy was associated with poor survival (HR=1.79, 95% CI:1.08-2.97, p=0.023, n=57). This predictor, however, was not significant in the test set (p=0.21, 26 events in 27 patients). CONCLUSION: The baseline level of uPAR(I-III)+uPAR(II-III) is a predictor of survival in inoperable...

    Full Text Available BACKGROUND AND PURPOSE: The benefit of concurrent chemoradiotherapy (CCRT in elderly patients with inoperable esophageal squamous cell carcinoma (SCC is controversial. This study aimed to assess the efficiency and safety of CCRT in elderly thoracic esophageal cancer patients. METHODS AND MATERIALS: Between January 2002 and December 2011, 128 patients aged 65 years or older treated with CCRT or radiotherapy (RT alone for inoperable thoracic esophageal SCC were analyzed retrospectively (RT alone, n = 55; CCRT, n = 73. RESULTS: No treatment-related deaths occurred and no patients experienced any acute grade 4 non-hematologic toxicities. Patients treated with CCRT developed more severe acute toxicities than patients who received RT alone. The 3-year overall survival (OS rate was 36.1% for CCRT compared with 28.5% following RT alone (p = 0.008. Multivariate analysis identified T stage and treatment modality as independent prognostic factors for survival. Further analysis revealed that survival was significantly better in the CCRT group than in the RT alone group for patients ≤ 72 years. Nevertheless, the CCRT group had a similar OS to the RT group for patients > 72 years. CONCLUSION: Our results suggest that elderly patients with inoperable thoracic esophageal SCC could benefit from CCRT, without major toxicities. However, for patients older than 72 years, CCRT is not superior to RT alone in terms of survival benefit.

    The aim of the present study was to assess the prognostic utility of the pretreatment blood neutrophil-to-lymphocyte ratio (NLR) and the C-reactive protein-to-albumin ratio (CAR) in patients with inoperable malignant pleural mesothelioma (MPM). The medical records of consecutive patients with histologically confirmed MPM from our hospital between January 2007 and August 2017 were retrospectively reviewed. The primary outcome was overall survival (OS). Univariate and multivariate analyses for the prognostic factors were performed using a Cox proportional hazards model. A total of 143 patients with inoperable MPM were included. On multivariate analysis, pretreatment CAR was an independent factor associated with worse OS (hazard ratio(HR)=1.72; 95% confidence interval(CI)=1.11-2.67; p=0.016). However, NLR was not associated with OS in any of the analyses. CAR appears to be a prognostic factor in patients with inoperable MPM.

    Radiotherapy is the first treatment of choice in cases of inoperable lung cancer. This paper reported the indications and limitations of radiotherapy for squamous cell carcinoma of the lung, based on the results of long-term survivors among non-resected squamous cell carcinoma. Materials consisted of 372 cases of squamous cell carcinoma of the lung treated with radiotherapy at the National Cancer Center Hospital between May 1962 and December 1980. Histopathological diagnosis was confirmed by biopsy in all cases. Among the 372 cases, 8 survived more than 5 years. Analyzing these 8 cases according to the TNM classification of the UICC, 7 were stage I, 1 was stage II, and there were no long-term survivors with stage III or IV. Of the 8 cases only one is alive. Analyzing 7 the fatal cases, 2 succumbed due to hepatic or brain metatasis following local recurrence and one had double primary cancer of the pancreas. The remaining 4 cases did not show recurrence or metastasis and succumbed due to pneumonia or myocardial infarct. (author)

    A retrospective study was made of the results of high dose radiotherapy (greater than or equal to 50 Gy) given to 171 patients with inoperable, intrathoracic non small cell lung cancer from January 1971-April 1973. Local control was dependent on the total tumor dose: after one year local control was 63% for patients treated with >65 Gy, the two year local control was 35%. If treated with 2 , the one year local control was 72%; the two year local control was 44%. Local control was also influenced by the performance status, by the localization of the primary tumor in the left upper lobe and in the periphery of the lung. Local control for tumors in the left upper lobe and in the periphery of the lung was about 70% after one year, and about 40% after two years. The one and two years survival results were correlated with the factors influencing local control. The dose factor, the localization factors and the performance influenced local control independently. Tumors localized in the left upper lobe did metastasize less than tumors in the lower lobe, or in a combination of the two. This was not true for the right upper lobe. No correlation between the TNM system, pathology and the prognosis was found

    In a prospective controlled clinical trial, 102 patients with inoperable non-small lung cancer (NSCLC), limited disease, stage II and III were treated with combination chemotherapy, cisplatin 70 mg/m 2 i.v. on day one and etoposide 100 mg/m 2 i.v. on day one, and etoposide 200 mg/m 2 orally on days 2 and 3, or radiotherapy given in 15 fractions of 2.8 Gy with two anterior/posterior fields during a period of three weeks. The patients completed a validated self-administered questionnaire before the start of treatment that assessed their psychosocial well-being, disease-related symptoms, personal functioning, and every day activity. These subjective varibles were evaluated together with treatment modality, WHO performance status, weight loss, and stage of disease, with regard to their value in predicting survival. Univariate survival analyses were undertaken for each individual factor, median survival was calculated according to life-table analyses. A step-wise multiple regression analysis was used to measure the prognostic value of the various factors. In the univariate analysis, general symptons (p=0.0006) psychosocial well-being (p=0.0002) and stage of disease (p=0.007) were the best predictive factors. In the multiple regression analyses the subjective variables, general symptons (p<0.01) and psychosocial well-being (p<0.05) were shown to have the best predictive value for the patients' survival.

    Full Text Available In recent years, there has been an increase in crude palm oil (CPO demand, resulting in palm oil mills (POMs seizing the opportunity to increase CPO production to make more profits. A series of equipment are designed to operate in their optimum capacities in the current existing POMs. Some equipment may be limited by their maximum design capacities when there is a need to increase CPO production, resulting in process bottlenecks. In this research, a framework is developed to provide stepwise procedures on identifying bottlenecks and retrofitting a POM process to cater for the increase in production capacity. This framework adapts an algebraic approach known as Inoperability Input-Output Modelling (IIM. To illustrate the application of the framework, an industrial POM case study was solved using LINGO software in this work, by maximising its production capacity. Benefit-to-Cost Ratio (BCR analysis was also performed to assess the economic feasibility. As results, the Screw Press was identified as the bottleneck. The retrofitting recommendation was to purchase an additional Screw Press to cater for the new throughput with BCR of 54.57. It was found the POM to be able to achieve the maximum targeted production capacity of 8,139.65 kg/hr of CPO without any bottlenecks.

    Image cytometry can measure numerous nuclear features which could be considered a surrogate end-point marker of molecular genetic changes in a nucleus. The aim of the study was to analyze image cytometric nuclear features in paired samples of primary tumor and neck metastasis in patients with inoperable carcinoma of the head and neck. Image cytometric analysis of cell suspensions prepared from primary tumor tissue and fine needle aspiration biopsy cell samples of neck metastases from 21 patients treated with concomitant radiochemotherapy was performed. Nuclear features were correlated with clinical characteristics and response to therapy. Manifestation of distant metastases and new primaries was associated (p<0.05) with several chromatin characteristics from primary tumor cells, whereas the origin of index cancer and disease response in the neck was related to those in the cells from metastases. Many nuclear features of primary tumors and metastases correlated with the TNM stage. A specific pattern of correlation between well-established prognostic indicators and nuclear features of samples from primary tumors and those from neck metastases was observed. Image cytometric nuclear features represent a promising candidate marker for recognition of biologically different tumor subgroups

    This study aimed to investigate the efficacy of fluorescence spectroscopy of gastric juice for early gastric cancer (EGC) screening. Gastric juice was collected from 101 participants who underwent endoscopy in the Outpatient Endoscopy Center of Peking University Third Hospital. The participants were divided into three groups: the normal mucosa or chronic non-atrophic gastritis (NM-CNAG) group (n = 35), advanced gastric cancer (AGC) group (n = 33) and EGC group (n = 33). Fluorescence spectroscopic analysis was performed in all the gastric juice samples and the maximum fluorescence intensity of the first peak (P1 FI) was measured. The mean fluorescence intensity of P1 FI of gastric juice in AGC (92.1 ± 10.7) and EGC (90.8 ± 12.0) groups was significantly higher than that in the NM-CNAG group (55.7 ± 7.5) (AGC vs NM-CNAG, P = 0.006 and EGC vs NM-CNAG, P = 0.015, respectively). The areas under the receiver operating characteristic curves for the detection of AGC and EGC were 0.681 (95% confidence interval [CI] 0.553-0.810, P = 0.010) and 0.655 (95% CI 0.522-0.787, P = 0.028). With the P1 FI of ≥47.7, the sensitivity, specificity and accuracy for detecting EGC were 69.7%, 57.1% and 63.2%, respectively. The enhancement of P1 FI of gastric juice occurs at the early stage of gastric cancer. Fluorescence spectroscopy of gastric juice may be used as a novel screening tool for the early detection of gastric cancer. © 2013 The Authors.

    To compare virtual gastroscopy using spiral CT with conventional endoscopy for the detection and evaluation of gastric lesions. During a previous six-month period, 30 patients with pathologically-proven gastric lesions underwent conventional endoscopy and virtual gastroscopy using spiral CT. There were 18 cases of advanced gastric carcinoma, eight benign ulcers, and four submucosal tumors(two leiomyomas, two lymphomas). Source images of virtual gastroscopy were three-dim-ensionally reconstructed within an Advantage Windows Workstation and virtual gastroscopic images were obtained using Navigator Software. On analysis, images were graded according to their quality(excellent, good, poor). Virtual gastroscopic images were interpreted by two radiologists blinded to conventional endoscopic findings, and were subsequently compared with endoscopic findings in terms of detectability and findings. In the cases of advanced gastric carcinoma, lesions were classified according to Borrmann's system. For virtual gastroscopy, overall image quality was excellent in 21 cases(70%), good in five(17%), and poor in four(13%). Lesions were detected in 25 cases(83%). Among the 18 advanced gastric carcinomas, virtual gastroscopy image quality was excellent in 14 cases(78%), good in two(11%), and poor in two(11%). Lesions were detected in 16 cases(89%). Two Borrmann type IV cases were not detected. Among the eight benign ulcers, virtual gastroscopy image quality was excellent in three cases(38%), good in three(38%), and poor in two(25%). The detection of lesion was possible in five cases(63%). In all submucosal tumors, virtual gastroscopy image quality was excellent. Lesions were detected in all cases. Virtual gastroscopy using spiral CT is safe and noninvasive, and for the evaluation of gastric lesions may be complementary to axial CT. It successfully detects gastric lesions, and in depicting the pattern of gastric folds its image quality is excellent.=20

    The problem is that current definitions of early gastric cancer allow the inclusion of regional lymph node metastases. The increasing use of endoscopic submucosal dissection to treat early gastric cancer is a concern because regional lymph nodes are not addressed. The aim of the study was thus to critically evaluate current evidence with regard to tumour-specific factors associated with lymph node metastases in "early gastric cancer" to develop a more precise definition and improve clinical management. A systematic and comprehensive search of major reference databases (MEDLINE, EMBASE, PubMed and the Cochrane Library) was undertaken using a combination of text words "early gastric cancer", "lymph node metastasis", "factors", "endoscopy", "surgery", "lymphadenectomy" "mucosa", "submucosa", "lymphovascular invasion", "differentiated", "undifferentiated" and "ulcer". All available publications that described tumour-related factors associated with lymph node metastases in early gastric cancer were included. The initial search yielded 1494 studies, of which 42 studies were included in the final analysis. Over time, the definition of early gastric cancer has broadened and the indications for endoscopic treatment have widened. The mean frequency of lymph node metastases increased on the basis of depth of infiltration (mucosa 6% vs. submucosa 28%), presence of lymphovascular invasion (absence 9% vs. presence 53%), tumour differentiation (differentiated 13% vs. undifferentiated 34%) and macroscopic type (elevated 13% vs. flat 26%) and tumour diameter (≤2 cm 8% vs. >2 cm 25%). There is a need to re-examine the diagnosis and staging of early gastric cancer to ensure that patients with one or more identifiable risk factor for lymph node metastases are not denied appropriate chemotherapy and surgical resection.

    Gastric cancer is the fourth most common malignancy worldwide. The incidence trends and mortality rates of gastric cancer in Israel have not been studied in depth. The aim of our study was to try and investigate the aforementioned issues in Israel in different ethnic groups. This retrospective study is based on the data of The Israel National Cancer Registry and The Central Bureau of Statistics. Published data from these two institutes were collected, summarized, and analyzed in this study. Around 650 new cases of gastric cancer are diagnosed yearly in Israel. While we noticed a decline during the period 1990-2007 in the incidence in the Jewish population (13.6-8.9 and 6.75-5.42 cases per 100,000 in Jewish men and women, respectively), an increase in the Arab population was noticed (7.7-10.2 and 3.7-4.2 cases per 100,000 in men and women, respectively). Age-adjusted mortality rates per 10,000 cases of gastric cancer decreased significantly, from 7.21 in 1990 to 5.46 in 2007, in the total population. The 5-year relative survival showed a slight increase for both men and women. There is a difference in the incidence and outcome of gastric cancer between the Jewish and Arab populations in Israel. The grim prognosis of gastric cancer patients in Israel is probably due to the advanced stage at which gastric cancer is diagnosed in Israel.

    Gastric cancer is one of the most common malignancies worldwide. During the last 50 years, the histological classification of gastric carcinoma has been largely based on Lauren's criteria, in which gastric cancer is classified into two major histological subtypes, namely intestinal type and diffuse type adenocarcinoma. This classification was introduced in 1965, and remains currently widely accepted and employed, since it constitutes a simple and robust classification approach. The two histological subtypes of gastric cancer proposed by the Lauren classification exhibit a number of distinct clinical and molecular characteristics, including histogenesis, cell differentiation, epidemiology, etiology, carcinogenesis, biological behaviors and prognosis. Gastric cancer exhibits varied sensitivity to chemotherapy drugs and significant heterogeneity; therefore, the disease may be a target for individualized therapy. The Lauren classification may provide the basis for individualized treatment for advanced gastric cancer, which is increasingly gaining attention in the scientific field. However, few studies have investigated individualized treatment that is guided by pathological classification. The aim of the current review is to analyze the two major histological subtypes of gastric cancer, as proposed by the Lauren classification, and to discuss the implications of this for personalized chemotherapy.

    Intrathoracic gastric volvulus is a very rare surgical emergency. Early diagnosis and treatment are of great importance to prevent gastric gangrene and perforation or gastric obstruction and dilation, which may lead to cardiorespiratory arrest. We report two infants who presented with intrathoracic gastric volvulus. This was associated with recurrent diaphragmatic hernia in one and congenital paraoesophageal hernia in the other. Aspects of diagnosis and treatment are also discussed. (orig.)

    2017-08-01

    Full Text Available Despite its declining incidence, gastric cancer (GC remains a leading cause of cancer-related deaths worldwide. A multimodal approach to GC is critical to ensure optimal patient outcomes. Pretherapy fine resolution contrast-enhanced cross-sectional imaging, endoscopic ultrasound and staging laparoscopy play an important role in patients with newly diagnosed ostensibly operable GC to avoid unnecessary non-therapeutic laparotomies. Currently, margin negative gastrectomy and adequate lymphadenectomy performed at high volume hospitals remain the backbone of GC treatment. Importantly, adequate GC surgery should be integrated in the setting of a multimodal treatment approach. Treatment for advanced GC continues to expand with the emergence of additional lines of systemic and targeted therapies.

    2014-01-01

    Gastric cancer is the second leading cause of cancer mortality worldwide. The diagnosis of gastric cancer has been significantly improved with the broad availability of gastrointestinal endoscopy. Effective technologies for accurate staging and quantitative evaluation are still in demand to merit reasonable treatment and better prognosis for the patients presented with advanced disease. Preoperative staging using conventional imaging tools, such as computed tomography (CT) and endoscopic ultrasonography, is inadequate. Positron emission tomography (PET), using 18F-fluorodeoxyglucose (FDG) as a tracer and integrating CT for anatomic localization, holds a promise to detect unsuspected metastasis and has been extensively used in a variety of malignancies. However, the value of FDG PET/CT in diagnosis and evaluation of gastric cancer is still controversial. This article reviews the current literature in diagnosis, staging, response evaluation, and relapse monitoring of gastric cancer, and discusses the current understanding, improvement, and future prospects in this area.

    Gastric cancer is the fourth most common type of cancer and represents a major cause of cancer-related deaths worldwide. With recent biomedical advances in our understanding of the molecular characteristics of gastric cancer, many genetic alterations have been identified as potential targets for its treatment. Multiple novel agents are currently under development as the demand for active agents that improve the survival of gastric cancer patients constantly increases. Based on lessons from previous trials of targeted agents, it is now widely accepted that the establishment of an optimal diagnostic test to select molecularly defined patients is of equal importance to the development of active agents against targetable genetic alterations. Herein, we highlight the current status and future perspectives of companion diagnostics in the treatment of gastric cancer.

    Inactivating mutations in the CDH1 (E-cadherin) gene are the predisposing cause of gastric cancer in most families with hereditary diffuse gastric cancer (HDGC). The lifetime risk of cancer in mutation positive members is more than 80 % and prophylactic total gastrectomy is recommended. Not all...... mutations in the CDH1 gene are however pathogenic and it is important to classify mutations before this major operation is performed. Probands from two Danish families with gastric cancer and a history suggesting HDGC were screened for CDH1 gene mutations. Two novel CDH1 gene mutations were identified....... Hospital stay was 6-8 days and there were no complications. Small foci of diffuse gastric cancer were found in all patients-intramucosal in six and advanced in one. Preoperative endoscopic biopsies had revealed a microscopic cancer focus in two of the patients. Our data confirmed the pathogenic nature...

    1998-01-01

    Purpose: To review our experience treating clinical Stage I non-small-cell lung carcinoma with radiotherapy alone using modern techniques and staging. The effect of dose and volume on outcome is to be analyzed. Methods: Between January 1980 and December 1995, 156 patients with Stage I medically inoperable non-small-cell lung cancer were irradiated at Duke University Medical Center and the Durham Veterans Administration Medical Center. Fifteen patients were excluded from analysis (7 treated with palliative intent, and 8 lost to follow-up immediately following radiation). Characteristics of the 141 evaluable patients were as follows: Median age 70 years (range 46-95); gender: male 83%, female 17%; institution: DUMC 65%, DVAMC 35%; T1N0 54%, T2N0 46%; median size 3 cm (range 0.5 to 8); pathology: squamous cell carcinoma 52%, adenocarcinoma 18%, large cell carcinoma 19%, not otherwise specified 11%; presenting symptoms: weight loss 26%, cough 23%, none (incidental diagnosis) 57%. All patients underwent simulation prior to radiotherapy using linear accelerators of ≥4 MV. No patients received surgery or chemotherapy as part of their initial treatment. The median dose of radiotherapy (not reflecting lung inhomogeneity corrections) was 64 Gy (50 to 80 Gy) given in 1.2 bid to 3 Gy qid fractionation. The majority of cases included some prophylactic nodal regions (73%). Results: Of the 141 patients, 108 have died; 33% of intercurrent death, 35% of cancer, and 7% of unknown causes. At last follow-up, 33 patients were alive (median 24 months, range 7-132 months). The 2- and 5-year overall survival was 39% and 13%, respectively (median 18 months). The corresponding cause-specific survival was 60%, and 32% (median 30 months). On multivariate analysis, significant factors influencing overall and/or cause-specific survival were age, squamous cell histology, incidental diagnosis, and pack-years of smoking. There was a nonsignificant trend towards improved cause-specific survival

    Full text: Most of the patients of hepatocellular carcinoma (HCC) present late with inoperable disease, cirrhosis of the liver and sometimes with portal vein thrombosis. In these circumstances, chemoembolisation is not possible. Similarly, if tumor is not accessible percutaneously, percutaneous ablative procedures are also ruled out. Such patients can be offered internal radionuclide therapy. In the internal radionuclide therapy, it is desirable to deliver the maximum possible radiation to the tumor, while protecting the critical organs such as normal liver parenchyma, lungs and the bone marrow (for which critical levels of radiation doses are predetermined as 30, 12 and 1.5 Gy, respectively). This is possible with individual dosimetry, by which radiation-absorbed dose/MBq to the various organs including the tumor is calculated and the 'maximum tolerated activity (MTA)', which can be safely administered to the patient, is estimated. However, this MTA should be able to deliver enough radiation to the tumor to ablate it completely (considered to be 80-100 Gy). We conducted trans-arterial Re-188 lipiodol therapy in patients with inoperable HCC after calculating MTA with individual dosimetry, in a multi-centric trial conducted by IAEA, and tried to evaluate whether calculated MTA could deliver tumoricidal radiation dose. With a transarterially injected scout dose (185 MBq) of Re-188, radiation absorbed dose to above mentioned organs including tumor were calculated in ten patients after acquiring planar gamma camera images, using conjugate view method (images taken up to 3 hrs post-injection along with a standard source) and performing first-order corrections for scatter (by taking images both in photopeak and scatter window) and attenuation (by taking a flood source and a transmission scan of the patents prior to the administration of Re-188). Images were acquired on gamma camera(Siemens-ORBITOR or GE- Millennium VG) with high/medium-energy collimator and radiation

    Purpose: The aggressiveness of radiation therapy for patients with medically inoperable endometrial carcinoma is controversial. Patients may die of their underlining medical disease before succumbing to cancer. We try to identify certain subgroup of patients who might benefit most from an aggressive approach and also investigate the impact of residual tumor present in dilatation and curettage (D and C) specimen obtained in second intracavitary implant (ICI). Methods and Materials: From 1965 to 1990, 101 patients were treated for clinical clinical Stage I endometrial carcinoma with RT alone due to medical problems. Ages ranged from 39 to 94 years (median 71 years). There were 18 patients with clinical Stage IA and 83 with clinical Stage IB disease. Histology included 44 well-differentiated, 37 moderately differentiated, and 20 poorly differentiated tumors. Radiation therapy consisted of external beam only in 3 patients, ICI alone in 26, whole pelvis plus ICI in 10, and whole pelvis plus split field plus ICI in 62. A second D and C was performed on 26 patients at the time of the second ICI. Minimum follow-up was 2 years (median, 6.3 years). Results: The 5-year actuarial disease-free survival (DFS) for the studied cohort is comparable to the expected survival of an age-matched population. Pelvic control was 100% for Stage IA and 88% for Stage IB with 5-year disease-free survivals of 80 and 84%, respectively. We also observed a greater disassociation of DFS and overall survival among patients older than 75 years (84 and 55%, respectively) than in younger patients (84 and 78%, respectively). This is mainly because older patients succumbed to their medical illness. Well-differentiated disease demonstrated the trend toward a better outcome than moderately or poorly differentiated lesions in Stage IB patients (p 0.05), but not in Stage IA patients. Aggressive radiation therapy approach showed the trend toward a better result in Stage IB patients 75 years of age or younger

    The aim of this study is to investigate the motivation, ability, preferences, and perceived potential facilitating factors/barriers of patients with inoperable metastatic lung cancer towards exercise programmes. This is a cross-sectional study using survey adopting the Theory of Planned Behaviour (TPB) to obtain patients' experience recruited through Odette Cancer Centre, Sunnybrook Health Sciences Complex. Results were expressed in percentages, P value, and Spearman's rho. Sixty patients were recruited from January 2014 to April 2014. Patients generally had a high level across TPB measures, with 63% of them indicating that they have the motivation to exercise. Significant association in relation to motivation was established on attitudes (importance, P = 0.005, rho = 0.326; helpfulness, P = 0.015, rho = 0.348; and easiness, P = 0.001, rho = 0.375) and subjective norm of close members (P = 0.0069, rho = 0.348) and healthcare professionals (P = 0.012, rho = 0.328). Being a non-smoker (P = 0.042, rho = 0.311), having a past exercise history prior to diagnosis (P = 0.000, rho = 0.563), and absence of COPD (P = 0.016, rho = -0.312) were also shown to have a significant association with motivation to exercise. Patients were motivated to participate in an exercise programme despite contrary belief; however, they might have limited ability and preferred light intensity type of exercise such as walking. Their motivation to exercise was driven by different factors when compared to other cancer patient populations. Thus, it is important for healthcare professionals to understand the factors influencing their motivation and increase their awareness (only 26% of patients indicated receiving advice regarding exercise) to better the care towards patients with metastatic lung cancer.

    INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39–79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p=0.005 and p=0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p=0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

    Epithelioid haemangioendothelioma (EHE) is a rare tumour of vascular origin, characterised by celular proliferation, endotelial, epitelioid or hystiocitoid. It may develop in any organ, but it is more common in lung and liver. Surgery is the recommended treatment; however, in case of a potentially benign situation, an expectant attitude should be adopted. The case reports a 71-year-old female who underwent a laparotomy for a colonic adenocarcinoma. During surgery, a polypoid lesion in the dependency of the gastric wall was found incidentally, which was removed. Histopathology and immunohistochemical analysis confirmed the diagnosis of EHE. Gastric vascular neoplasms represent about 0.9-3.3% of all gastric tumours. Usually have a good prognosis, but due to the borderline biological behaviour of these tumours, it is important to have a detailed clinical evaluation at follow-up of these patients.

    Few studies have evaluated metabolic activity by {sup 18}F-FDG PET as a prognostic factor in advanced gastric cancer (AGC). We investigated its prognostic role in metastatic AGC. We enrolled 82 patients with metastatic AGC, who were treatment-naive and underwent pretreatment {sup 18}F-FDG PET/CT scanning. In each patient, the maximal standardized uptake value (SUVmax) was measured in each target lesion. Stomach{sub SUVmax} was defined as SUVmax in the stomach, while Total{sub SUVmax} was defined as the highest SUVmax among all the target lesions. The stomach was the organ most frequently displaying the highest SUVmax among all the target lesions (in 67.1 % of patients). A Total{sub SUVmax} value of 11.5 was the value with the maximum sum of sensitivity and specificity from receiver-operating characteristic curves for progression-free survival (PFS). PFS was significantly longer in patients with a Total{sub SUVmax} value <11.5 than in those with a Total{sub SUVmax} value {>=}11.5 (P = 0.023); however, overall survival (OS) was not (P = 0.055). A Stomach{sub SUVmax} value of 6.0 was derived by similar methods. PFS and OS were significantly longer in those with a Stomach{sub SUVmax} value <6.0 than in those with a Stomach{sub SUVmax} value {>=}6.0 (P = 0.001 and P = 0.006, respectively). Furthermore, those with a low Total{sub SUVmax} and those with a low Stomach{sub SUVmax} showed better chemotherapeutic responses (P = 0.016 and P = 0.034, respectively). Among patients with histologically undifferentiated carcinomas, those with lower Total{sub SUVmax} and those with lower Stomach{sub SUVmax} showed longer median PFS (P = 0.027 and P = 0.005, respectively) and OS (P = 0.009 and P <0.001, respectively). Multivariate analysis demonstrated Stomach{sub SUVmax} as an independent predictor of PFS (P = 0.002) and OS (P = 0.038). Pretreatment metabolic activity may be a useful prognostic marker in patients with metastatic AGC undergoing palliative chemotherapy. Notably

    Radiotherapy remains the basic form of treatment in cases of non-small cell lung cancer (NSCLC) but there still exist controversies concerning optimal radiotherapy regimen and in particular, the total dose and fractionation schedules. To prove whether the question: if using an unconventional dose fractionation regimen (accelerated hyperfractionation) could improve the results of palliative teleradiotherapy patients with NSCLC. Between 1997 and 2000 in the Cancer Centre in Cracow (COOK) a controlled clinical trial was conducted in a group of 150 patients with locally advanced (III Deg) inoperable and unsuitable for radical radiotherapy NSCLC, with no major symptoms of the disease. In 76 patients conventionally fractionated radiotherapy was performed - 50 Gy in 25 fractions during 5 weeks (CF). 74 patients were irradiated twice a day (AHF); the dose per fraction was 1.25 Gy and the minimum interval between fractions - 6 hours. The total dose was 50 Gy in 40 fractions during 26 days. The probability of 12 months survival was 47.4% in the CF arm and 45.9% in the AHF arm; the probability of 24 months survival was 16.2% and 15.8%, respectively. In all 76 patients in CF arm the treatment was carried out in prescribed time without breaks. Out of 74 patients in the A HF group 8 (10,8%) did not complete the treatment and 2 of then died in 3rd and 4th week of treatment. The use of accelerated hyperfractionation does not improve the results of palliative teleradiotherapy in patients with locally advanced NSCLC without severe symptoms related to intrathoracic tumor. The treatment of choice in this group of patients os conventionally fractionated radiotherapy with a total dose of 50 Gy in 25 fractions in 5 week of treatment. (author)

    To compare the results of patients with locally advanced breast cancer receiving two different regimens Fluorouracil, Doxorubicin and Cyclophosphamide (FAC) and Paclitaxel and Carboplatin. Study Design: Comparative study. Place and Duration of Study: The Oncology Department, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, from March 2007 to September 2008. Methodology: Patients with inoperable locally advanced breast cancer of stage were included. Sixteen patients were given FAC regimen and 9 patients were given Paclitaxel and Carboplatin, each combination was cycled after 21 days for four times. Before enrollment, detailed medical histories, physical examinations and performance status assessments were done as well as post chemotherapy evaluation with regular follow-up visits was done. Complete Response (CR, 100%) is defined as the disappearance of all known disease parameter i.e. disappearance in detectable tumour size, node free disease and surgery is possible. Paratial Response (PR, > 50%) was defined by 50% or greater decrease in the sum of the areas of bidimensionally measured lesions i.e. change of N2 to N1 or no status and some surgical procedure is possible to down stage the disease. Minor Response (MR) was defined as a decrease in the tumour insufficient to quality for partial resp once. Static disease or no evaluable reflected no significant change in disease and no evidence of new disease. Progression of disease (> 25%) was defined as a 25% or greater increase in the area of any lesion > 2 cm or in the sum of the products of the individual lesions or the appearance of new malignant lesions, surgery not possible. Results: Twenty five patients completed neoadjuvant chemotherapy. Sixteen (66%) patients received FAC and 9 (37%) patients received PC chemotherapy. Overall CR (breast and axilla) was 54%, PR was 16% and minor response (MR) was 8%. FAC treatment induced more emesis, mucositis, alopecia and cardiotoxicity. No death occurred

    Gastric cancer is a leading cause of cancer-related mortality worldwide. Cancer stem cells are the source of tumor recurrence and metastasis. Self-renewal is a marker of cancer stem cells and also the basis of long-lasting survival and tumor progression. Although the mechanism of gastric cancer stem cell self-renewal is not clear, there are several signaling pathways and environmental factors known to be involved. This mini review describes recent developments in the self-renewal signaling pathway of gastric cancer stem cell research. Advancements made in this field of research will likely support the development of novel therapeutic strategies for gastric cancer.

    Gastric cancer is among the most common human malignancies and the second leading cause of cancer-related death. The different epidemiologic and histopathology of subtypes of gastric cancer are associated with different genomic patterns. Data suggests that gene expression patterns of proximal, distal gastric cancers-intestinal type, and diffuse/signet cell are well separated. This review summarizes the genetic and epigenetic changes thought to drive gastric cancer and the emerging paradigm of gastric cancer as three unique disease subtypes.

    Purpose: Concomitant chemoradiotherapy (CRT) increases survival rates compared with radical radiotherapy alone (RT) in Stage III non-small-cell lung cancer (NSCLC), as a result of improved local control. The effect of CRT on local control in Stage I NSCLC is less well documented. We retrospectively reviewed local control and survival following CRT or RT for inoperable Stage I NSCLC patients. Methods and materials: Eligible patients had histologically/cytologically proved inoperable Stage I NSCLC and had undergone complete staging investigations including an F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scan. Radiotherapy was planned as (1) 60 Gy in 30 fractions over 6 weeks with or without concomitant chemotherapy or (2) 50-55 Gy in 20 fractions without chemotherapy. Results: Between 2000 and 2005, 73 patients met the eligibility criteria and were treated as follows: CRT (60 Gy)-39; RT (60 Gy)-23; RT (50-55 Gy)-11. The median follow-up time for all patients was 18 months (range, 1-81 months). Survival analysis was based on intent to treat. Local progression-free survival (PFS) at 2 years was 66% with CRT and 55% with RT. The 2-year distant PFS was 60% following CRT and 63% after RT. The 2-year PFS rates were 57% and 50%, respectively. The 2-year survival rate for patients treated with CRT was 57% and 33% in patients receiving RT. Conclusions: Despite the use of CRT and routine staging with FDG-PET, both local and distant recurrences remain important causes of treatment failure in patients with inoperable stage I NSCLC.

    Purpose: to investigate the feasibility, toxicity, and efficacy of external-beam reirradiation (Re-RT) combined with cetuximab for patients with inoperable and recurrent squamous cell carcinoma of the head and neck (SCCHN). Patients and methods: seven patients with inoperable recurrence of SCCHN after adjuvant or definitive radiotherapy (RT) and simultaneous or sequential cisplatin-based chemotherapy for primary SCCHN were treated between August and December 2008 with Re-RT (1.8 Gy/fraction to 50.4 Gy) and cetuximab (400 mg/m 2 initial dose in the 1st week, and then 250 mg/m 2 once weekly). Recurrence had to be located at least ≥ 50% in the preirradiated field. Long term toxicity from previous treatment was recorded before Re-RT as a baseline value. Acute and late toxicity derived from the experimental regimen were recorded every week during RT, and then every 3 months. Efficacy was assessed with repeated imaging using response evaluation criteria in solid tumors (RECIST) and clinical examinations 8-12 weeks after end of the treatment and every 3 months thereafter (Tables 1 and 2). Results: only mild localized mucositis occurred in all patients. Two patients developed a grade 3 acneiform rash related to cetuximab. After treatment one patient developed a grade 2 trismus, another showed grade 3 abacterial salivary gland inflammation with severe pain requiring opioid medication. Two patients achieved a complete response after 7 months, one remained stable, three progressed, and one died from pneumonia without having restaging magnetic resonance imaging. Conclusion: A second course of RT combined with cetuximab in patients with inoperable, recurrent HNSCC proved to be feasible with mild or moderate toxicity and encouraging response to treatment.

    Background Aim of this prospective study was to evaluate the effects of exercise training in patients with inoperable or residual chronic thromboembolic pulmonary hypertension (CTEPH). Methods Thirty-five consecutive patients with invasively confirmed inoperable or residual CTEPH (16 women;19 men; mean age 61±15 years, mean pulmonary artery pressure, 63±20 mmHg; primary inoperable n = 33, persisting pulmonary hypertension after pulmonary endarterectomy n = 2) on stable disease-targeted medication received exercise training in-hospital for 3 weeks and continued at home for 15 weeks. Medication remained unchanged during the study period. Efficacy parameters have been evaluated at baseline, after 3 and 15 weeks by blinded-observers. Survival rate has been evaluated in a follow-up period of median 36.4 months (interquartile range 26.6–46.6 months). Results All patients tolerated exercise training without severe adverse events. Patients significantly improved the mean distance walked in 6 minutes compared to baseline by 61±54 meters after 3 weeks (p<0.001) and by 71±70 meters after 15 weeks (p = 0.001), as well as scores of quality-of-life questionnaire, peak oxygen consumption and maximal workload. NT-proBNP improved significantly after 3 weeks of exercise training (p = 0.046). The 1-year survival rate was 97%, 2-year survival rate was 94% and the 3-year-survival 86% respectively. Conclusion Training as add-on to medical therapy may be effective in patients with CTEPH to improve work capacity, quality of life and further prognostic relevant parameters and possibly improves the 1-, 2- and 3-year survival rate. Further multicentric randomized controlled studies are needed to confirm these promising results. Trial Registration ClinicalTrials.gov NCT01398345 PMID:22848542

    Advances in Endoscopic submucosal dissection (ESD) technology have established ESD for early gastric cancer as a safe and stable technique. However, ESD may induce delayed gastric emptying and the cause of food residue retention in the stomach after ESD is not clear. This study aimed to clarify risk factors for delayed gastric emptying with food retention after gastric ESD. We retrospectively examined for food residue in the stomach 1 week after ESD was performed for early gastric carcinoma at Osaka Saiseikai Nakatsu Hospital from February 2008 to November 2016. Food residue was observed in 68 (6.1%) of 1114 patients who underwent gastric ESD. The percentage of lesions located on the lesser curvature of the upper third of the stomach was 45.6% (31/68) in the food residue group and 3.5% (37/1046) in the non-food residue group, which was significantly different (P gastric ESD. Of the 68 patients, 3 had food residue in the stomach on endoscopic examination for follow-up observation after the ESD ulcer had healed. Delayed gastric emptying with food retention after gastric ESD was associated with lesions located in the lesser curvature of the upper stomach, submucosal invasion of the lesion, age older than 80 years, and post-ESD bleeding, though it was temporary in most cases.

    SAR125844 is a potent and selective inhibitor of the c-Met kinase receptor. This was an open-label, phase I, multicenter, dose-escalation, and dose-expansion trial of SAR125844 in Asian patients with solid tumors, a subgroup of whom had gastric cancer and MET amplification (NCT01657214). SAR125844 was administered by intravenous infusion (260-570 mg/m 2 ) on days 1, 8, 15, and 22 of each 28-day cycle. Objectives were to determine the maximum tolerated dose (MTD) and to evaluate SAR125844 safety and pharmacokinetic profile. Antitumor activity was also assessed. Of 38 patients enrolled (median age 64.0 years), 22 had gastric cancer, including 14 with MET amplification. In the dose-escalation cohort ( N = 19; unselected population, including three patients with MET -amplification [two with gastric cancer and one with lung cancer]), the MTD was not reached, and the recommended dose was established at 570 mg/m 2 . Most frequent treatment-emergent adverse events (AEs) were nausea (36.8%), vomiting (34.2%), decreased appetite (28.9%), and fatigue or asthenia, constipation, and abdominal pains (each 21.1%); none appeared to be dose-dependent. Grade ≥ 3 AEs were observed in 39.5% of patients and considered drug-related in 7.9%. SAR125844 exposure increased slightly more than expected by dose proportionality; dose had no significant effect on clearance. No objective responses were observed in the dose-escalation cohort, with seven patients (three gastric cancer, two colorectal cancer, one breast cancer, and one with cancer of unknown primary origin) having stable disease. Modest antitumor activity was observed at 570 mg/m 2 in the dose-expansion cohort, comprising patients with MET -amplified tumors ( N = 19). Two gastric cancer patients had partial responses, seven patients had stable disease (six gastric cancer and one kidney cancer), and 10 patients had progressive disease. Single-agent SAR125844 administered up to 570 mg/m 2 has acceptable tolerability and modest

    This review compares the safety and efficacy of boron neutron capture therapy (BNCT) in the treatment of previously irradiated, inoperable locoregional recurrent HNC patients and compares BNCT against the standard treatment of platinum-based chemotherapy. Our analysis of published clinical trials highlights efficacy of BNCT associated with mild side effects. However, the use of BNCT should be explored in stratified randomised trials. - Highlights: • BNCT can prolong median overall survival. • BNCT can be associated with severe adverse effects. • BNCT may be comparable to chemotherapy-based regimens. • BNCT may be comparable to re-irradiation techniques regimens in patients with low performance status.

    Gastric cancer is the most common gastrointestinal malignancy in Korea. Identification and evaluation of gastric mass lesions and regional-distant metastasis by abdominal CT scan are important for the treatment planning and prognostic implications of gastric cancer patients. Author reviewed CT scans of 61 cases of pathology proven gastric cancer, retrospectively, for recent 20 month from July 1983 to Feb. 1985 at Department of Radiology, Korea University, Hae Wha Hospital. The results were as follows: 1. There were 50 cases of advanced adenocarcinoma, 8 cases of early gastric cancer, 2 cases of leiomyosarcoma, and 1 case of lymphoma in total 61 cases. 2. The sex ratio of male to female was 2 : 1. Age distribution was from 24 to 75 year old and peak incidence was in 6th decade. 3. The most frequent site of involvement with gastric cancer was gastric antrum in 51% 4. 48 of 50 patients with advanced gastric adenocarcinoma (96%) had a wall thickness greater than 1 cm, and all of 8 cases of early gastric cancer had a wall thickness less than 1 cm. Regional lymph node tumor infiltration was found in 100% of gastric wall thickness greater than 2.0 cm, in 64% of cases of 1.5 to 2.0 cm, in 50% of cases of 1.0 to 1.5 cm, and 12.5% of cases of less than 1.0 cm. 5. In a comparison of enlargement of regional lymph node by CT scan to tumor infiltration of regional lymph node by histology, sensitivity was 52%, specificity was 87%, and reliability was 66%. 6. The structure involved by distant metastasis of these cases were the retroperitoneal lymph node in 15, liver in 8, and pancreas in 3. 7. The diagnostic accuracy of CT staging was considered about 68% by correlation of the surgical and histological findings. 8. The CT scan is one of the accurate and simple tool for evaluation of size, shape, extent, as well as distant metastasis in the cases of gastric malignancies

    Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.

    Because various mastication-related factors influence gastric activity, the functional relationship between mastication and gastric function has not been fully elucidated. To investigate the influence of mastication on gastric emptying and motility, we conducted a randomized trial to compare the effects of mastication on gastric emptying and gastric myoelectrical activity under conditions that excluded the influences of food comminution, taste, and olfaction. A (13)C-acetate breath test with electrogastrography and electrocardiography was performed in 14 healthy men who ingested a test meal with or without chewing gum. Autonomic nerve activity was evaluated by fluctuation analysis of heart rate. Gastric emptying was significantly delayed in the 'ingestion with mastication' group. Gastric myoelectrical activity was significantly suppressed during mastication and increased gradually in the post-mastication phase. A decrease in the high-frequency power of heart rate variability was observed coincidentally with gastric myoelectrical activity suppression. These findings suggest that initial gastric emptying is suppressed by mastication, and that the suppression is caused by mastication-induced inhibition of gastric activity (UMIN Clinical Trial Registration no. UMIN000005351).

    Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and increase distant metastasis free survival. IORT is the modality which could increase local control without increasing complication, combined with curative operation. Even though we could achieve significant decreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988, and performed 53 IORT in patients with gastric cancer. No local failure has been report? by regular follow up so far. Nine cases(17%) of treatment related complication were reported including intestinal obstruction, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo 25.2% (chemotherapy + operation), Kim 18% (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500 cGy), external irradiation(--4500 cGy) and extensive chemotherapy (FAM, 5FU+MMC, BACOP). Our data encouraged us to re-inforce further IORT in stomach cancer treatment

  16. Gastric microbiota and carcinogenesis: the role of non-Helicobacter pylori bacteria: a systematic review

    Directory of Open Access Journals (Sweden)

    Emanuel Dias-Jácome

    Full Text Available Background and aim: Helicobacter pylori is the strongest risk factor for gastric cancer. However, recent advances in DNA sequencing technology have revealed a complex microbial community in the stomach that could also contribute to the development of gastric cancer. The aim of this study was to present recent scientific evidence regarding the role of non-Helicobacter pylori bacteria in gastric carcinogenesis. Methods: A systematic review of original articles published in PubMed in the last ten years related to gastric microbiota and gastric cancer in humans was performed. Results: Thirteen original articles were included. The constitution of gastric microbiota appears to be significantly affected by gastric cancer and premalignant lesions. In fact, differences in gastric microbiota have been documented, depending on Helicobacter pylori status and gastric conditions, such as non-atrophic gastritis, intestinal metaplasia and cancer. Gastric carcinogenesis can be associated with an increase in many bacteria (such as Lactobacillus coleohominis, Klebsiella pneumoniae or Acinetobacter baumannii as well as decrease in others (such as Porphyromonas spp, Neisseria spp, Prevotella pallens or Streptococcus sinensis. However, there is no conclusive data that confirms if these changes in microbiota are a cause or consequence of the process of carcinogenesis. Conclusions: Even though there is limited evidence in humans, microbiota differences between normal individuals, pre-malignant lesions and gastric cancer could suggest a progressive shift in the constitution of gastric microbiota in carcinogenesis, possibly resulting from a complex cross-talk between gastric microbiota and Helicobacter pylori. However, further studies are needed to elucidate the specific role (if any of different microorganisms.

    Full text of publication follows. Aim: in the last years Peptide Receptor Radionuclide Therapy (PRRT) acquired greater importance as an alternative or complementary treatment of neuroendocrine tumors (NETs) and other somatostatin receptor positive (sstr+) tumors. Many studies about PRRT using different radiopharmaceuticals, mainly 90 Y and 177 Lu (beta-emitters) labelled peptides, are reported in the literature. 177 Lu-labeled somatostatin analogues seem to be more effective because of their favourable physical properties and the better objective response. On the other hand, only few reports exist on PRRT using 111 In-Pentetreotide, an Auger-emitter. The aim of this study is to evaluate the usefulness of 111 In-Pentetreotide therapy in patients with sstr+ inoperable benign intracranial tumors in which the use of beta-emitters radiopharmaceuticals (characterized by higher penetration range) could be unsafe and questionable since lesions were close to critical anatomical structures, such as optic chiasm or medulla oblongata. Materials and methods: we retrospectively reviewed clinical records of 9 patients (7 Females and 2 Males) affected by sstr+ benign intracranial tumors (mean age: 58.4 years, range 50-81): 8 patients had meningiomas/meningiomatosis and 1 patient had a pituitary macroadenomas. A previous diagnostic scintigraphy with 111 In-Pentetreotide demonstrated high intralesional radiotracer uptake. All patients underwent PRRT with high therapeutic activities of 111 In-Pentetreotide (1-7 cycles, median 4 cycles, activity per cycle 3.7-7.5 GBq, median activity per cycle 7 GBq, cumulative activity range 13.7-66 GBq). Efficacy of PRRT was evaluated according to RECIST criteria. Toxicity was also assessed considering hematological parameters and GFR value estimated by renal dynamic scintigraphy. Results: no patient had acute damage. Complete response was observed in 1 patient (11.1%). Partial response was observed in 2 patients (22.2%); stable disease was observed

    The chemokine CXCL12 and its receptor CXCR4 can affect tumor growth, recurrence, and metastasis. We tested the hypothesis that the CXCL12 and CXCR4 expression influences the prognosis of patients with inoperable head and neck cancer treated with definite radiotherapy or chemoradiotherapy. Formalin-fixed paraffin-embedded pretreatment tumor tissue from 233 patients with known HPV/p16{sup INK4A} status was analyzed. CXCL12 and CXCR4 expressions were correlated with pretreatment parameters and survival data by univariate and multivariate Cox regression. CXCL12 was expressed in 43.3 % and CXCR4 in 66.1 % of the samples and both were correlated with HPV/p16{sup INK4A} positivity. A high CXCL12 expression was associated with increased overall survival (p = 0.036), while a high CXCR4 expression was associated with decreased metastasis-free survival (p = 0.034). A high CXCR4 expression could be regarded as a negative prognostic factor in head and neck cancer because it may foster metastatic spread. This may recommend CXCR4 as therapeutic target for combating head and neck cancer metastasis. (orig.)

    In 2010, the World Health Organization classified gastric neuroendocrine tumors (NETs) into three types: NET grade (G) 1, NET G2 and neuroendocrine carcinoma (NEC). NECs are associated with a very poor prognosis. The patient was an 84-year-old female who was initially diagnosed by gastrointestinal endoscope with type 3 advanced gastric cancer with stenosis of the gastric cardia. Her overall status and performance status did not allow for operations or intensive chemotherapy. Palliative radiotherapy was performed and resulted in a significant reduction in the size of the tumor as well as the improvement of the obstructive symptoms. She died 9 months after radiotherapy. An autopsy provided a definitive diagnosis of gastric endocrine cell carcinoma, and the effectiveness of radiotherapy was pathologically-confirmed. Palliative radiotherapy may be a useful treatment option for providing symptom relief, especially for old patients with unresectable advanced gastric neuroendocrine carcinoma. (author)

    Gastric cancer is a deadly malignancy afflicting close to a million people worldwide. Patient survival is poor and largely due to late diagnosis and suboptimal therapies. Disease heterogeneity is a substantial obstacle, underscoring the need for precision treatment strategies. Studies have identified different subgroups of gastric cancer displaying not just genetic, but also distinct epigenetic hallmarks. Accumulating evidence suggests that epigenetic abnormalities in gastric cancer are not mere bystander events, but rather promote carcinogenesis through active mechanisms. Epigenetic aberrations, induced by pathogens such as Helicobacter pylori, are an early component of gastric carcinogenesis, probably preceding genetic abnormalities. This Review summarizes our current understanding of the gastric cancer epigenome, highlighting key advances in recent years in both tumours and pre-malignant lesions, made possible through targeted and genome-wide technologies. We focus on studies related to DNA methylation and histone modifications, linking these findings to potential therapeutic opportunities. Lessons learned from the gastric cancer epigenome might also prove relevant for other gastrointestinal cancers.

    Background and purpose: To report patterns of failure of stereotactic body radiation therapy (SBRT) in inoperable patients with histologically confirmed stage I NSCLC. Materials and methods: Ninety-two inoperable patients (median age: 75 years) with clinically staged, histologically proven T1 (n = 31) or T2 (n = 61), N0, M0 non-small cell lung cancer (NSCLC) were included in this study. Treatment consisted of 3–5 fractions with 7–15 Gy per fraction prescribed to the 60% isodose. Results: Freedom from local recurrence at 1, 3 and 5 years was 89%, 83% and 83%, respectively. All 10 local failures were observed in patients with T2 tumors. Isolated regional recurrence was observed in 7.6%. The crude rate of distant progression was 20.7%. Overall survival at 1, 3, and 5 years was 79%, 38% and 17% with a median survival of 29 months. Disease specific survival at 1, 3, and 5 years was 93%, 64% and 48%. Karnofsky performance status, T stage, gross tumor volume and tumor location had no significant impact on overall and disease specific survival. SBRT was generally well tolerated and all patients completed therapy as planned. Conclusion: SBRT for stage I lung cancer is very well tolerated in this patient cohort with significant cardiopulmonal comorbidity and results in excellent local control rates, although a considerable portion develops regional and distant metastases.

    The gastric epithelium is continuously regenerated by gastric stem cells, which give rise to various kinds of daughter cells, including parietal cells, chief cells, surface mucous cells, mucous neck cells, and enteroendocrine cells. The self-renewal and differentiation of gastric stem cells need delicate regulation to maintain the normal physiology of the stomach. Recently, it was hypothesized that cancer stem cells drive the cancer growth and metastasis. In contrast to conventional clonal ev...

    Gastric polyps are often an incidental finding on upper gastrointestinal endoscopy, with an incidence up to 5%. The majority of gastric polyps are asymptomatic, occurring secondary to inflammation. Prior reviews discussed Helicobacter pylori (H pylori)-associated singular gastric polyposis; however, we present a rare and unusual case of recurrent multiple benign gastric polyposis post H pylori eradication resulting in intermittent gastric outlet obstruction. A 70-year-old independent male, Chinese in ethnicity, with a background of diabetes mellitus, hypertension, and a simple renal cyst presented with a combination of melena, anemia, and intermittent vomiting of partially digested food after meals. Initial gastroscopy was positive for H pylori; thus he was treated with H pylori eradication and proton pump inhibitors. Serial gastroscopy demonstrated multiple sessile gastric antral polyps, the largest measuring 4 cm. Histopathologic examination confirmed a benign hyperplastic lesion. Computed tomography identified a pyloric mass with absent surrounding infiltration or metastasis. A distal gastrectomy was performed, whereby multiple small pyloric polyps were found, the largest prolapsing into the pyloric opening, thus explaining the intermittent nature of gastric outlet obstruction. Such polyps often develop from gastric ulcers and, if left untreated, may undergo neoplasia to form malignant cells. A distal gastrectomy was an effective choice of treatment, taking into account the polyp size, quantity, and potential for malignancy as opposed to an endoscopic approach, which may not guarantee a complete removal of safer margins and depth. Therefore, surgical excision is favorable for multiple large gastric polyps with risk of malignancy.

    The National Comprehensive Cancer Network clinical practice guidelines in oncology-gastric cancer guidelines have been widely used to provide appropriate recommendations for the treatment of patients with gastric cancer. The aim of this study was to examine the adherence of surgical oncologists, medical oncologists, and radiation oncologists' to the recommended guidelines. A questionnaire asking the treatment options for gastric cancer cases was sent to 394 Chinese oncology specialists, including surgical oncologists, medical oncologists, and radiation oncologists working in hospitals joined in The Western Cooperative Gastrointestinal Oncology Group of China. The questionnaire involved a series of clinical scenarios regarding the interpretation of surgery, neoadjuvant, adjuvant, and advanced treatment planning of gastric cancer. Analysis of 358 respondents (91%) showed variations between each specialization and from the recommended guidelines in the management approaches to specific clinical scenarios. The majority of specialists admitted that less than 50% of patients received multidisciplinary evaluation before treatment. The participants gave different responses to questions involving adjuvant, neoadjuvant, and advanced settings, compared to the recommended guidelines. These results highlight the heterogeneity of the treatment of gastric cancer. Surgical oncologists, medical oncologists, and radiation oncologists are not adhering to the recommended guidelines

    Abstract Malignant gastric outlet obstruction is a late complication of intraabdominal malignancy. Self-expandable metallic stent placement has been a safe palliative treatment to relieve obstructive symptoms. We aimed to assess the efficacy and safety of metallic stents in our patients and analyzed the clinical outcome of different brands. Seventy-one patients with inoperable gastric outlet obstruction receiving WallFlex enteral stents (WallFlex group) or Bonastents (Bonastent group) since April 2010 were analyzed retrospectively. The overall technical and clinical success rates of stent placement were 100% and 93%, respectively. The baseline characteristics and clinical outcomes including procedure-related complications, restenosis, and reintervention rates were comparable between the 2 groups. However, the Bonastent group had a higher rate of stent fracture than the WallFlex group (13.3% vs 0%, P = 0.03). The mean duration of overall stent patency was 132.7 days. The mean duration of survival was 181.9 days. Resumption of regular diet or low residual diet at day 7 after stent insertion predicted stent patency (hazard ratio [HR]: 0.28, P = 0.01). Cancer with gastric origin (HR: 0.25, P = 0.045) and poststent chemotherapy (HR: 0.38, P = 0.006) predicted lower mortality; however, peritoneal carcinomatosis (HR: 3.09, P = 0.04) correlated with higher mortality. Metallic stent placement is a safe and effective method for relieving gastric outlet obstruction. Except higher rate of stent fracture in the Bonastent group, there is no significant difference in clinical outcomes between the Bonastent group and the WallFlex group. PMID:26200641

    Gastric emptying of a semiliquid test meal with 5 MBq /sup 99m/Tc-sulfur colloid as a marker was measured in 97 chronic dyspeptic patients and 16 healthy subjects. A comparison of half emptying time between both showed that chronic dyspeptic patients empty semiliquid meal at a significantly (p < 0.005) slower rate (at 70 +- 33 min) than healthy controls (at 52 x 20 min). The studies indicate that gastric stasis in chronic dyspepsia is not caused by inflammatory changes in gastric or duodenal mucosa nor by different gastric acid secretion. The presence of stasis cannot be predicted sufficiently by anamnestic complaints or endoscopic findings. (author)

    Gastric Schwannoma is a rare benign intramural tumor arising from the stomach, and it accounts for only 0.1% of all the different kinds of gastric neoplasms, and it's less than 4% of all the benign gastric tumors. This tumor is very difficult to differentiate from the other mesenchymal tumors by the clinical, endoscopic and radiologic findings. In this study, we demonstrate the appearance of this tumor on endoscopic ultrasound and contrast-enhanced abdomen CT. We also show the histopathologic findings of a surgically confirmed gastric Schwannoma that was located in the proper muscle layer

    Full Text Available Purpose. To examine the relationship between esophageal and gastric cancers commonly seen in Van Lake region and the traditional eating habits of the geography. Materials and Methods. Esophageal and gastric cancer cases, who underwent surgery between January 1, 2012, and December 31, 2013, were examined. Pathology reports of the patients and presence of Helicobacter pylori (HP were recorded. Surveys were filled by face to face meeting or telephone call. Control group was created with randomly selected individuals without any cancer diagnosis having age, gender, and socioeconomic characteristics similar to patient group. All data were analyzed using SAS.9.3 statistical programme. Results. Compared with the control group, herby cheese consumption (a component of eating habits and smoking were significantly higher in the patient group (P<0.001. Tandoor exposure is compared in terms of female gender, and significant difference was found between the groups (P=0.0013. As a result of the analysis with logistic regression more than 150 gr of herby cheese consumption per day was found to increase the cancer risk (odds ratio 1.017; 95% CI: 1.012–1.022. Conclusion. A high consumption of herby cheese, cooking bread on tandoor, and heavy smoking were seen to be important risk factors for esophageal and gastric cancers.

    Full Text Available The aim of this case-control study, conducted in Serbia during the period 1998-2000, was to investigate whether diet was associated with the development of gastric cancer. The case group consisted of 131 patients with histologically confirmed gastric cancer, and the control group of 131 patients with orthopedics diseases and injuries. Cases and controls were individually matched by age (±± 2 years, gender, and place of residence. On the basis of multivariate logistic regression analysis, following factors were found as independent risk factors for gastric cancer: more frequent consumption of high-fat milk [Odds ratio (OR =1.45, 95% confidence interval (CI = 0.99-2.16]; mutton, lamb and/or calf meat (OR = 2.46, 95% CI = 1.11-5.47, sugar (OR = 2.13, 95% CI = 1.43-3.18, semi-white bread (OR = 2.09, 95% CI = 1.25-3.50, and salting food (OR = 5.72, 95% CI = 2.63-12.42. Factors found as protective were: more frequent consumption of margarine (OR = 0.41, 95% CI = 0.25-0.69, „other“ cheeses (OR = 0.47, 95% CI = 0.29 - 0.77, and fish (OR = 0.39, 95% CI = 0.19-0.76.

    Full Text Available A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. Trichobezoar is a rare condition seen almost exclusively in young women with trichotillomania and trichotillophagia. When not recognized, the trichobezoar continues to grow, which increases the risk of severe complications such as gastric ulceration and even perforation. Formation of a gallstone within the trichobezoar (tricholithobezoar is an event that has not yet been described. We report the case of a 22-year-old woman admitted to the emergency room with signals and symptoms of an epigastric mass and perforative acute abdomen. Radiological study revealed bilateral pneumoperitoneum. Personal history revealed depressive syndrome, trichotillomania and trichophagia. With a diagnosis of visceral perforation, an urgent exploratory laparotomy was performed. This confirmed the diagnosis of gastric perforation due to a large trichobezoar with the formation of a gastrolith that was removed by anterior gastrotomy. Biochemical study of the gastric stone revealed that it was composed of bile salts. There were no complications. The patient was discharged on the 5th postoperative day and was referred for psychiatric treatment.

    Objective: To study the feasibility of obliteration with NBCA(N-Butyl-2-Cyanoacrylate)for the treatment of gastric bleeding varices in terminal stage of portal hypertension. Methods: All 17 cases of upper gastrointestinal hemorrhage with portal hypertension, mean age 54 years, including 11 cases of advanced hepatocellular carcinoma with portal venous tumor emboli, 6 eases of cirrhosis and 3 cases with moderate to severe ascites; were selected for this study. According to the Child-Pugh classification, 3 cases were in class B and 14 cases in class C at admission. Left gastric, posterior and short gastric varices were shown in all patients on CT or MRI enhancement scannings, together with splenorenal and gastrorenal shunts in 3 and 3 cases respectively. Seven cases were approached through right midaxillary line transhepatic route, 4 cases through infra-cartilago ensiformis transhepatic route, and 6 cases through transsplenic approach. Nine eases took scheduled operation, and 8 cases under emergency operation. According to blood flow rate and variceal internal diameter, the proportion 1:4 of NBCA and lipiodol was selected for the embolization. The survival and symptom relief of the patients were followed up. Results: All cases were successfully engaged in embolization with NBCA, with all varices disappeared on post-operation angiography and CT enhancement scanning during follow-up. Pressure of portal vein rised 3 cmH 2 O after operation with one case having with transient irritable cough. The average survival time was over 5 months during 3-12 months follow-up. Four cases died postoperatively because of hepatic function exhaustion. Conclusion: Utilization of NBCA in obliteration for gastric bleeding varices is effective, feasible and reliable; with less complication, Keeping strict indications would surely raise the long-term efficacy.

    Purpose: To assess the use of brachytherapy (BT) with or without external beam radiation (EBRT) in inoperable stage I endometrial adenocarcinoma in the United States and to determine the effect of BT on overall survival (OS) and cause-specific survival (CSS). Methods and Materials: Data between 1998 and 2011 from the National Cancer Institute's Surveillance, Epidemiology and End Results database were analyzed. Coarsened exact matching was used to adjust for differences in age and grade between patients who received BT and those who did not. Prognostic factors affecting OS and CSS were evaluated using the Kaplan-Meier product-limit method and a Cox proportional hazards regression model. Results: A total of 460 patients with inoperable stage I endometrial adenocarcinoma treated with radiation therapy were identified. Radiation consisted of either EBRT (n=260) or BT with or without EBRT (n=200). The only factor associated with BT use was younger patient age (median age, 72 vs 76 years, P=.001). Patients who received BT had a higher 3-year OS (60% vs 47%, P<.001) and CSS (82% vs 74%, P=.032) compared with those who did not. On multivariate analysis, BT use was independently associated with an improved OS (hazard ratio [HR] 0.67, 95% confidence interval [CI] 0.52-0.87) and CSS (HR 0.61, 95% CI 0.39-0.93). When patients were matched on age, BT use remained significant on multivariate analysis for OS (HR 0.65, 95% CI 0.48-0.87) and CSS (HR 0.52, 95% CI 0.31-0.84). When matched on age and grade, BT remained independently associated with improved OS and CSS (OS HR 0.62, 95% CI 0.46-0.83; CSS HR 0.57, 95% CI 0.34-0.92). Conclusion: Brachytherapy is independently associated with improved OS and CSS. It should be considered as part of the treatment regimen for stage I inoperable endometrial cancer patients undergoing radiation.

    Objective: To assess the technical feasibility and effectiveness of fluoroscopically-guided transnasal insertion of ileus tube for intestinal decompression in the treatment of inoperable malignant bowel obstruction. Methods: A total of 211 patients with inoperable malignant bowel obstruction were enrolled in this study. The median KPS scale was 40 (ranged from 20 to 60). Under fluoroscopic guidance, transnasal insertion of ileus tube by using conventional technique or guidewire-catheter exchange technique was performed in all patients. The technical success rate, the clinical effective rate, the curative rate and adverse reactions as well as complications were documented. The correlation among the obstructive sites, obstruction causes and therapeutic effectiveness was analyzed. The ileus tube used in this study was a four-cavity and double-balloon catheter with a diameter of 16 F/18 f, which is produced by Cliny Company. Results: Transnasal drainage tube was successfully inserted into the proximal jejunum in all 211 patients with malignant bowel obstruction, and the total technical success rate was 100%. The initial technical success rate of the traditional technique and the catheter-guidewire exchange method was 85.5% (65/76) and 100% (135/135) respectively, the difference between the two was significant (P<0.05). After 24 hours, the clinical remission rate in the patients with high-level intestinal obstruction, lower-level intestinal obstruction and colorectal obstruction was 95.8% (46/48), 92.9% (117/126) and 83.8% (31/37), respectively. A follow-up of 4-245 days (mean 138 days) was conducted, and the total clinical cure rate was 27.5% (58/211). The clinical cure rate in small intestine obstruction and colorectal obstruction caused by primary tumor or recurrence was 12.7% (20/157) and 59.5% (22/37), respectively (P<0.05). The adverse reactions and complications included uncomfortable pharynx feeling or pain (99.1%, 199/221), the tube obstruction (23.2%, 49

    Ten gastric cancer A-bomb survivors who had been false negative in mass screening for gastric cancer one year before the diagnosis were entered in a study determining an adequate interval of gastric mass screening for A-bomb survivors. Doubling time of cancer was determined on X-ray films. Of the 10 A-bomb survivors, 8 had entered the city after the bombing and the other two had been exposed at 1,700 m and 2,500 m, respectively, from the hypocenter. Six had early gastric cancer and the other 4 had advanced cancer. Doubling time averaged 19.1 months for early cancer and 7.6 months for advanced cancer. Three measurements of tumor diameter available for 4 A-bomb survivors revealed a very rapid increase in doubling time during the progression period from early to advanced cancer. An interval of one year seems to be adequate in mass screening to detect early cancer. (N.K.)

    Full Text Available The obesity epidemic has burdened healthcare systems worldwide. Bariatric surgery is currently the most effective method for long-term weight loss in obese adults, but the exact mechanism of weight loss is poorly understood. Bariatric procedures were initially classified by their presumed mechanism of action into restrictive, malabsoptive, or mixed procedures; however, due to recent advancements in the field of neuroendocrinology, hormones are increasing being recognized as important regulators of satiation, hunger, and energy expenditure. Studies examining changes in gut hormones following bariatric surgery have yielded conflicting results and the relationship between these hormones and weight loss is nothing but clear. This review will summarize the effect of Roux en Y gastric bypass, sleeve gastrectomy and adjustable gastric banding on various gut hormones including ghrelin, cholecystokinin, glucagon-like polypeptide-1, peptide YY3, and pancreatic polypeptide. Furthermore, the relationship between these hormones and weight loss will be examined.

    Animal models have greatly enriched our understanding of the molecular mechanisms of numerous types of cancers. Gastric cancer is one of the most common cancers worldwide, with a poor prognosis and high incidence of drug-resistance. However, most inbred strains of mice have proven resistant to gastric carcinogenesis. To establish useful models which mimic human gastric cancer phenotypes, investigators have utilized animals infected with Helicobacter species and treated with carcinogens. In addition, by exploiting genetic engineering, a variety of transgenic and knockout mouse models of gastric cancer have emerged, such as INS-GAS mice and TFF1 knockout mice. Investigators have used the combination of carcinogens and gene alteration to accelerate gastric cancer development, but rarely do mouse models show an aggressive and metastatic gastric cancer phenotype that could be relevant to preclinical studies, which may require more specific targeting of gastric progenitor cells. Here, we review current gastric carcinogenesis mouse models and provide our future perspectives on this field. PMID:24216700

    Objective: To investigate the clinical effect of metallic stent implantation together with intra-arterial chemotherapy in treating malignant gastric and duodenal obstruction. Methods: A total of 32 patients with malignant gastric and duodenal obstruction were enrolled in this study. The obstructed sites were located at the gastric sinus and pylorus part (n=16), at the gastroduodenal anastomotic stoma (n=6) or at the descending part of duodenum (n=10). Under DSA guidance and with the additional help of endoscopy, a guide-wire was orally placed in the gastroduodenal obstructed site, which was followed by the implantation of the self-expanding metallic stent (Ni-Ti alloy). Postoperative intra-arterial chemotherapy via the tumor-feeding arteries was carried out in 16 patients (dual interventional therapy). The clinical results were analyzed. Results: Successful stent insertion was achieved in all 32 patients (100%). After stent implantation the obstructive symptoms were markedly relieved and the food intake was improved. No serious complications occurred. The median survival time for the 16 patients who had received dual interventional therapy was 9.3 months, while the median survival time for the other 16 patients who had received simple stenting therapy was 5.7 months. Conclusion: For the treatment of inoperable malignant gastroduodenal obstruction, the implantation of metallic self-expanding stents is a technically simple, clinically safe and effective palliative measure. Combined with postoperative intra-arterial chemotherapy, the metal stent implantation can control the tumor growth and elongate the survival time. (authors)

    Objective: To evaluate the therapeutic efficacy and treatment-related toxicity of stereotactic body radiation therapy (SBRT) in patients with medically inoperable stage I/II non-small cell lung cancer (NSCLC). Methods: SBRT was applied to 30 patients, including clinically staged T 1 , T 2 (≤5 cm) or T 3 (chest wall primary tumors only), N 0 , M 0 ,biopsy-confirmed NSCLC. All patients were precluded from lobotomy because of physical condition or comorbidity. No patients developed tumors of any T-stage in the proximal zone. SBRT was performed with the total dose of 50 Gy to 70 Gy in 10 - 11 fractions during 12 - 15 days. prescription line was set onthe edge of the PTV. Results: The follow-up rate was 100%. The number of patients who completed the 1-, and 2-year follow-up were 15, and 10, respectively. All 30 patients completed therapy as planned. The complete response (CR), partial response (PR) and stable disease (SD) rates were 37%, 53% and 3%, respectively. With a median follow-up of 16 months (range, 4-36 months), Kaplan-Meier local control at 2 years was 94%. The 2-year overall survival was 84% and the 2-year cancer specific survival was 90%. Seven patients(23%) developed Grade 2 pneumonitis, no grade > 2 acute or late lung toxicity was observed. No one developed chest wall pain. Conclusions: It is feasible to deliver 50 Gy to 70 Gy of SBRT in 10 - 11 fractions for medically inoperable patients with stage I / II NSCLC. It was associated with low incidence of toxicities and provided sustained local tumor control.The preliminary investigation indicated the cancer specific survival probability of SBRT was high. It is necessary to perform similar investigation in a larger number of patients with long-term follow-up. (authors)

    Objective: To retrospectively analyze treatment results of radiotherapy for medically inoperable stage I/II non-small cell lung cancer. Methods: Between Jan. 2000 and Dec. 2005, fifty-eight such patients were enrolled into the database analysis, including 37 with clinical stage I and 21 with stage II disease. Fifty patients received radiotherapy alone and eight with radiotherapy and chemotherapy. Forty- three patients were treated with 3-D conformal radiotherapy (3D-CRT) and 15 with conventional radiotherapy. Results: The 1-, 2- and 3-year overall survival rates were 85%, 54% and 30%, and the median survival time was 26.2 months for the whole group. The corresponding figures were 88%, 60%, 36% and 30.8 months for cancer-specific survival; 84%, 64%, 31% and 30.8 months for Stage I disease; 81%, 47%, 28% and 18.8 months for Stage II disease; 95%, 57%, 33% and 30.8 months for 3D-CRT group and 53%, 44%, 24% and 15.3 months for conventional radiotherapy group. By logrank test, tumor volume, pneumonitis of Grade II or higher and weight loss more than 5% showed statistically significant impact on overall survival. Tumor volume was the only independent prognostic factor in Cox multivariable regression. Pneumonitis and esophagitis of Grade II or higher were 16% and 2%, respectively. Age and lung function before treatment had a significant relationship with pneumonitis. Failure included the local recurrence (33%) and distant metastasis (21%). There was no difference between the treatment modalities and failure sites. Conclusions: For medically inoperable early stage non-small cell lung cancer patients, tumor volume is the most important prognostic factor for overall survival. The conformal radiotherapy marginally improves the survival. The age and pulmonary function are related to the incidence of treatment induced pneumonitis. (authors)

    The purpose of this study was to determine the impact of overall treatment time on long-term survival after high-dose radiation therapy alone for inoperable non-small cell lung cancer (NSCLC). Between 1978 and 1990, 229 patients with stage I-III disease and Karnofsky Performance Scores of 80-100 received a conventionally fractionated total dose of 70 Gy through a split-course technique. After a first treatment course of 40 or 50 Gy, a rest aging was performed and only patients without any contraindications, such as newly diagnosed distant metastases or serious deterioration of performance status, were given a second course. In 83% of patients this break lasted for 4-6 weeks. Overall treatment time ranged between 7 and 24 weeks (median 12 weeks). Median follow-up time was 6.6 years (range 4.0-9.3 years). Actuarial overall survival rates at 2 and 5 years were 28% and 7% respectively. Complete radiological tumor response was observed in 31% of patients, and was found to be the strongest positive predictor of survival with 2- and 5-year rates of 50% and 12% respectively compared with 17% and 4% for patients without complete response. Treatment duration was not found to be a significant prognostic factor in univariate or multivariate analysis. For overall treatment times of 7-11 weeks (n=50), 12 weeks (n=79) and >12 weeks (n=100), 5-year survival was 4%, 6%, and 8%, respectively (p=0.6). To conclude, in our experience and in contrast to other studies, prolonged overall treatment times in radiation therapy alone for inoperable NSCLC had no negative impact on long-term survival. It is hypothesized that accelerated tumor cell repopulation is absent in a significant number of these patients with the time-factor playing no apparent role for outcome of treatment. (orig.)

    Iris metastasis in patients with gastric cancer is extremely rare. Herein, it is aimed to report on a patient with gastric adenocarcinoma and iris metastasis. A 65-year-old patient with the history of gastric cancer was admitted for eye pain and eye redness on his left eye. There was ciliary injection, severe +4 cells with hypopyon in the anterior chamber and a solitary, friable, yellow-white, fleshy-creamy vascularized 2 mm × 4 mm mass on the upper nasal part of the iris within the left eye. The presented patient's mass lesion in the iris fulfilled the criteria of the metastatic iris lesion's appearance. The ocular metastasis occurred during chemotherapy. Iris metastasis can masquerade as iridocyclitis with pseudohypopyon or glaucoma. In patients with a history of gastric cancer that present with an iris mass, uveitis, and high intraocular pressure, ocular metastasis of gastric cancer should be a consideration.

    Gastric carcinoids (GCs) or neuroendocrine tumours (NETs) are increasingly identified at endoscopy, and account for 0.6-2% of all gastric polyps identified. The SEER database in the US has demonstrated a rising incidence of gastric NETs amongst all NETs; from 2.2% between 1950 and 1969 to 6.0% between 2000 and 2007. To review the literature and assist clinicians in managing patients with GCs. A literature search was conducted through MEDLINE using search terms: gastric, carcinoid, neuroendocrine tumour, therapy, endoscopy, mucosal resection, submucosal dissection. Relevant articles were identified through manual review. The reference lists of these articles were reviewed to include further appropriate articles. There are three types of GCs with important epidemiological, pathophysiological, histological and endoscopic differences that affect prognosis and management. Type 1 and 2 GCs develop in the context of hypergastrinaemia that originates from achlorhydria in atrophic gastritis and a gastrinoma, respectively. Type 3 GCs occur sporadically and independent of gastrin. The histological type, grade and Ki67 index are used to determine prognosis and direct clinical management. Type 1 GCs >1 cm in size and type 2 GCs should be assessed for invasion beyond the submucosa with EUS prior to endoscopic resection with EMR or ESD. Type 3 GCs should be managed as per recommendations for gastric adenocarcinoma. The treatment of advanced disease is multimodal. Patients with gastric carcinoids should be discussed in a specialist neuroendocrine tumour multidisciplinary meeting to ensure all treatment options are explored in localised and advanced disease. Areas of controversy exist that need further research. © 2014 John Wiley & Sons Ltd.

    Gastric varices that arise secondary to the splenic vein occlusion can result in gastrointestinal hemorrhaging. Endoscopic color Doppler ultrasonography (ECDUS) was performed in 16 patients with gastric varices secondary to splenic vein occlusion. This study retrospectively evaluated the role of ECDUS in the diagnosis of gastric varices secondary to splenic vein occlusion. Thirteen patients had co-existing pancreatic diseases: 8 with chronic pancreatitis, 4 with cancer of the pancreatic body or tail and 1 with severe acute pancreatitis. Of the remaining 3 patients, 1 had myeloproliferative disease, 1 had advanced gastric cancer, and the third had splenic vein occlusion due to an obscure cause. The endoscopic findings of gastric varices were: variceal form (F) classified as enlarged tortuous (F2) in 12 cases and large, coil-shaped (F3) in 4 cases, and positive for erosion or red color sign of the variceal surface in 4 cases and negative in 12 cases. ECDUS color flow images of gastric variceal flow clearly depicted a round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body in all 16 cases. The velocities of F3 type gastric varices were significantly higher than those of the F2 type. The wall thickness of varices positive for erosion or red color sign was significantly less than the negative cases. I conclude that ECDUS color flow images of gastric variceal flow depicted specific findings of gastric varices secondary to splenic vein occlusion at the round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body.

    The relationship between the apoptosis and the expression of proliferating cell nuclear antigen (PCNA) and the clinical stages in gastric cancers was studied. By using terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) technique and PCNA immunohistochemical staining, the apoptosis and the expression of PCNA in tissue of gastric carcinoma were assayed in situ, the index of apoptosis (AI), index of PCNA (PI) and the rate of AI/PI were calculated. AI and PI in gastric cancer tissues were (6.5 +/- 3.7)% and (49.8 +/- 15.9)% respectively, and the rate of AI/PI was 0.13 +/- 0.05, which were obviously different from those of normal gastric mucosa in paragastric cancer (P stages of gastric carcinoma, the AI was decreased, PI was increased and the rate of AI/PI decreased in gastric carcinoma. There was significant difference in them between the gastric cancer tissues and normal gastric mucosa in pericarcinoma in TNM stage II to IV (P gastric carcinoma. The AI, PI and the rate of AI/PI would become the prognostic factors in advanced gastric carcinoma.

    Full Text Available Objective: To study the relationship of preoperative gastric cancer CT enhancement ratio and perfusion parameters with serum tumor marker levels and proliferation molecule expression in tumor lesions. Methods: A total of 68 patients with gastric cancer treated in the Second Hospital of Yulin City between May 2012 and May 2016 were chosen as observation group and sub-divided into early and middle gastric cancer group (n=41 and advanced gastric cancer group (n=27 according to the tumor stage; 50 patients diagnosed with benign gastric diseases in our hospital during the same period were selected as benign gastric lesion group. CT enhancement rate and perfusion parameters of three groups of patients were detected by CT scan, serum tumor marker levels were evacuated by enzyme-linked immunosorbent assay (ELISA, and the proliferation gene mRNA expression levels were detected by RTPCR method. Results: CER, AF, BV and CL levels of advanced gastric cancer group were higher than those of early and middle gastric cancer group and benign gastric lesion group; serum CA72-4, CA19-9, CA125 and CEA contents of advanced gastric cancer group were higher than those of early and middle gastric cancer group and benign gastric lesion group; CADM1, miRNA-34a and Cystatin M mRNA expression in tissue of advanced gastric cancer group were lower than those of early and middle gastric cancer group and benign gastric lesion group while Survivin and I2PP2A mRNA expression were higher than those of early and middle gastric cancer group and benign gastric lesion group. The Pearson test showed that the CT enhancement rate and perfusion parameters in patients with gastric cancer are directly correlated with the serum tumor marker levels and the proliferation gene expression in tumor lesions. Conclusion: Preoperative gastric cancer CT enhancement rate and perfusion parameters are directly related to the tumor malignancy, and can be used as a reliable method for the long-term tumor

    Background/Aims Endoscopic submucosal dissection (ESD) has become accepted as a minimally invasive treatment for gastric neoplasms. However, the development of synchronous or metachronous gastric lesions after endoscopic resection has become a major problem. We investigated the characteristics of multiple gastric neoplasms in patients with early gastric cancer (EGC) or gastric adenoma after ESD. Methods In total, 512 patients with EGC or gastric adenoma who had undergone ESD between January 2008 and December 2011 participated in this study. The incidence of and factors associated with synchronous and metachronous gastric tumors were investigated in this retrospective study. Results In total, 66 patients (12.9%) had synchronous lesions, and 13 patients (2.5%) had metachronous lesions. Older (> 65 years) subjects had an increased risk of multiple gastric neoplasms (p = 0.012). About two-thirds of the multiple lesions were similar in macroscopic and histological type to the primary lesions. The median interval from the initial lesions to the diagnosis of metachronous lesions was 31 months. The annual incidence rate of metachronous lesions was approximately 3%. Conclusions We recommend careful follow-up in patients of advanced age (> 65 years) after initial ESD because multiple lesions could be detected in the remnant stomach. Annual surveillance might aid in the detection of metachronous lesions. Large-scale, multicenter, and longer prospective studies of appropriate surveillance programs are needed. PMID:24307844

    Full Text Available In chronic thromboembolic pulmonary hypertension, stenoses or obstructions of the pulmonary arteries due to organized thrombi can cause an elevation in pulmonary artery resistance, which in turn can result in pulmonary hypertension. Chronic thromboembolic pulmonary hypertension can be cured surgically by pulmonary endarterectomy; however, patients deemed unsuitable for pulmonary endarterectomy due to lesion, advanced age, or comorbidities have a poor prognosis and limited treatment options. Recently, advances have been made in balloon pulmonary angioplasty for these patients, and this review highlights this recent progress.

    Gastric cancer perforation can occurs in advanced stage of the disease and is often associated with a high morbidity and mortality. Peritonitis due to perforation needs emergency laparotomy and different surgical procedures can be performed for definitive treatment. Surgical procedures largely depend on the stage of the disease and general condition of the patient. This study was carried out to evaluate the outcome and role of different surgical procedures in gastric cancer perforation. Medical record of patients with gastric perforation, who were treated during ten years period, was reviewed retrospectively. Data regarding clinical presentation, surgical procedures, staging and survival of patients were obtained. Features suggestive of diffuse peritonitis were evident in all cases. The majority of the patients underwent emergency surgery except one who died during resuscitation. The majority of patients were in stage III and stage IV. Surgical procedure includes simple closure and omental patch in five patients, simple closure and gastrojejunostomy in nine patients, gastrectomy in six patients and Devine's antral exclusion in one patient. Surgical site infection was the most common (45.5%) postoperative complication. Four patients died within one month of the surgery. Three patients who underwent gastrectomy survived for one year and one patient survived for five years. Although gastric cancer perforation usually occurs in advanced stage of the disease, curative resection should be considered as far as possible.

    AFP-producing gastric cancer(AFPGC) and hepatoid adenocarcinoma of the stomach (HAS) are two special subtypes of gastric cancer. There are both correlation and difference between them. AFPGC is usually identified as primary gastric cancer with serum AFP level more than 20 ng/ml or showed AFP positive staining by immunohistochemistry. The diagnosis of HAS is mainly dependent on the pathological character of hepatocellular carcinoma-like differentiation of gastric cancer. The morbidity of AFPGC and HAS are rather low, especially the incidence of HAS is about 1%. The prognoses of these two subtypes are poorer than that of common gastric adenocarcinoma, due to a high incidence rate of liver metastasis and lymph node metastasis. With the development of next-generation sequencing and other genomic technologies, gastric cancers, including these two rare subtypes, are now being investigated in more detail at the molecular level. Treatment remains the biggest challenge, early diagnosis and radical resection can dramatically improve patients'prognosis. Monitoring serum AFP and abdominal imaging examination during follow-up is important for early detection of liver metastasis. In combination with local treatment methods such as transarterial chemoembolization and radiofrequency ablation of liver may further extend patients'survival time. Targeted therapy owes a great potential value in the future.

    To demonstrate the feasibility and clinical efficacy of self-expanding, covered metallic stent placement for the palliative treatment of malignant gastric obstruction. Under fluoroscopic guidance, the placement of self-expanding, covered stents was attempted in 23 patients (age range, 31-78 years) with inoperable or recurrent gastric malignancies. All 23 suffered dysphagia and/or vomiting after the ingestion of soft foods, or swallowing difficulty. Three different types of self-expanding, covered metallic stents were used and in all patients, these were placed perorally using over the guide wire technique. Success was defined both technically and clinically. Stent placement was technically successful in 19 patients (82.6%) but because the guidewire failed to successfully negotiate the sites at which there was obstruction, was unsuccessful in four (17.4%). Stent placement was well tolerated in all patients except one, in whom an acutely angled efferent loop from remnant stomach was present. In this case, stent placement required a strong metallic guidewire. After placement, 17 of the 19 patients (89.5%) were able to ingest solid and/or soft foods without dysphagia and showed a markedly decreased incidence of vomiting. Two others showed some improvement in the frequency of vomiting but were able to ingest only a liquid diet. In one patient, the stent migrated two days after the procedure. During the follow-up period of 2-7 months (mean, 74 days), there were no clinically significant complications. For the short-term palliative treatment of patients with gastric inlet or outlet obstruction, the placement of self-expanding metallic stents has proven relatively easy and safe, as well as reasonably effective.

    The incidence of gastrointestinal stromal tumours (GIST) has increased in recent years. A number of authors have attempted to define the actual nature of these tumours. Immunohistochemistry highlighting the positivity of tyrosine-kinase (CD117/c-Kit) has revealed the difference between gastrointestinal stromal tumours and other mesenchymal tumours and, therefore, the possibility of medical rather than surgical therapy. We retrospectively reviewed 19 patients affected by primary gastric GIST, who underwent surgery in recent years with subsequent follow-up. Gastroscopy and gastrointestinal tract radiography were used not only to obtain the diagnosis but also to establish the size, density, contours, ulceration, regional lymphadenopathy, mesenteric infiltration and the presence of metastases. The aim of this study was to evaluate the roles of endoscopy and radiology in this pathology and the advantages and limitations of each individual technique.

    Considering the various comorbidities associated with aging, the feasibility and usefulness of concurrent chemoradiotherapy (CRT) in older patients with inoperable non-small cell lung cancer (NSCLC) is a controversial issue. Here, we compared the feasibility of CRT and the effects of various comorbidities on the prognosis of a minimally selected population of inoperable NSCLC patients aged 60-77 years. The study comprised 161 patients with inoperable NSCLC who received CRT with a target radiation dose greater than 60 Gy and platinum-based chemotherapy from 1998 to 2007. The total population included 69 patients aged 60-69 years and 53 aged 70-77 years. These two age cohorts were included in the study with a follow-up of a median 14.5 months. The two groups showed no differences in long-term survival, as reflected by the 5-year survival rates of 13.0 ± 4.1 % (60- to 69-year-olds) and 14.4 ± 4.9 % (70- to 77-year-olds). During the treatment phase, the groups were comparable in terms of toxicity and the feasibility of chemotherapy. Compared to patients in their 60s, the septuagenarians had more pulmonary comorbidities (p = 0.02), diabetes mellitus (p = 0.04), cardiac comorbidities (p = 0.08), and previous cancer disease (p = 0.08) that exerted a negative effect on survival. In patients without comorbidities, there were no differences between the age groups. Age is not a contraindication for concurrent CRT per se, because elderly patients do not have a worse long-term prognosis than younger seniors. However, ''elderly patients'' (≥ 70-77 years) have more concomitant diseases associated with shorter survival than ''moderately aged patients'' (≥ 60-69 years). (orig.)

    Full Text Available Background: The perioperative use of epirubicin, cisplatin, and fluorouracil (ECF significantly improves outcomes in patients with gastric and gastro-oesophageal (GO cancers but is cumbersome to administer. Given the equivalence of epirubicin, oxaliplatin, and capectabine (EOX with ECF in advanced setting, we analyzed the compliance, efficacy, and toxicity of perioperative EOX in resectable but locally advanced cancers. Methods: This is a retrospective analysis of prospectively maintained database of patients treated between January 2012 and September 2013 at Tata Memorial Centre. Patients were planned to receive 3# of neoadjuvant (NA and 3# of adjuvant EOX (intravenous epirubicin 50 mg/m 2 D1, oxaliplatin 130 mg/m 2 , on D1, capecitabiine 1250 mg/m 2 D1-21 every 21 days. On completion of NA therapy, patients were planned to undergo gastrectomy and D2 lymphadenectomy. Results: A total of 99 patients (76% males, median age 51 years were treated with perioperative EOX. Preoperatively, 93% patients completed EOX. Post-NA chemotherapy, 4 patients progressed, 1 patient died and 94 were taken up for surgery. Of these, 9 were inoperable and 85 patients underwent radical surgery. Of these, 71% (60/85 were able to complete three cycles of adjuvant EOX. The compliance to complete all 6 cycles of perioperative chemotherapy was 64%. Grade 3 and 4 toxicities were comparable to the MAGIC dataset apart from higher number of diarrhea in our patients. Conclusions: In patients with resectable GO adenocarcinoma, it is possible to deliver the MAGIC-type perioperative chemotherapy with EOX with better compliance, toxicity, and efficacy rates.

    There have been sporadic reports about synchronous as well as metachronous gastric adenocarcinoma and primary gastric lymphoma. Many reports have dealt with metachronous gastric adenocarcinoma in mucosa-associated lymphoid tissue lymphoma of stomach. But to our knowledge, there have been no reports that document the increased incidence of metachronous gastric adenocarcinoma in patients with gastric diffuse large B-cell lymphoma. This retrospective study was conducted to estimate the incidence of metachronous gastric adenocarcinoma after primary gastric lymphoma treatment, especially in diffuse large B-cell lymphoma. The retrospective cohort study of 139 primary gastric lymphoma patients treated with radiotherapy at our hospital. Mean observation period was 61.5 months (range: 3.7-124.6 months). Patients profile, characteristics of primary gastric lymphoma and metachronous gastric adenocarcinoma were retrieved from medical records. The risk of metachronous gastric adenocarcinoma was compared with the risk of gastric adenocarcinoma in Japanese population. There were 10 (7.2%) metachronous gastric adenocarcinoma patients after treatment of primary gastric lymphomas. It was quite high risk compared with the risk of gastric carcinoma in Japanese population of 54.7/100,000. Seven patients of 10 were diffuse large B-cell lymphoma and other 3 patients were mixed type of diffuse large B-cell lymphoma and mucosa associated lymphoid tissue lymphoma. Four patients of 10 metachronous gastric adenocarcinomas were signet-ring cell carcinoma and two patients died of gastric adenocarcinoma. Metachronous gastric adenocarcinoma may have a more malignant potential than sporadic gastric adenocarcinoma. Old age, Helicobacter pylori infection and gastric mucosal change of chronic gastritis and intestinal metaplasia were possible risk factors for metachronous gastric adenocarcinoma. There was an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma

    Full Text Available Gastric adenomyoma is a rare benign tumor composed of epithelial structures and smooth muscle stroma. Here, we report an unusual case of gastric adenomyoma mostly composed of smooth muscle that was incidentally found during a laparoscopic intervention. On radiology, it mimicked an acquired hypertrophic pyloric stenosis in an adult patient, and pathologically it resembled a pure smooth muscle hamartoma. Complete submission of the lesion for histology was necessary to find the epithelial component and make the right diagnosis. As a mimicker of benign and malignant entities, gastric adenomyoma is usually an unexpected finding after surgery. The aim of this report is to analyze this adenomyoma variant in the setting of an unexplained thickening of the gastric wall, with explanations concerning histogenesis and biological potential.

    627 cases of gastric cancer treated surgically during the last 5 years, at the Hospital Nacional "Edgardo Rebagliati Martins" from Instituto Peruano de Seguridad Social (Lima-Perú) were revised. 4 of the patients had been operated before of hemigastrectomy or antrectomy with pyloroplasty for peptic ulcer. The time between the first operation and diagnosis of cancer of the gastric stump was more than 20 years. 3 of these cases were able to be resected. The international incidence of cancer in the gastric stump is 1.1% to 9.2% according to different authors. The risk is higher after 15 years. In the pathogenesis are advocated the lower gastric acidity, biliary reflux, the presence of bacteria, the formation of nitrosamines, intestinal metaplasia, etc. Is necessary to perform periodic endoscopic survey in patients who were treated surgically of peptic ulcer with antrectomy or hemigastrectomy with more than 15 years of evolution.

    A recent development of novel anticancer agents like S-1, CPT-11 or taxanes has improved a therapeutic outcome for advanced gastric cancer, while conventional anticancer agents showed less anticancer effect against gastric cancer. The present main drug in Japan is S-1, which is easily used for outpatient with a high efficacy rate and low toxicity, also shows better effect in combination with other anticancer drugs than S-1 alone. In the present article, we demonstrated significant meaning of additional radiation therapy with anticancer drugs like S-1. With novel anticancer drugs like S-1, we will expose a clinical advantage and appropriateness for chemo-radiation therapy against gastric cancer discussed in the present references according to chemo-radiation therapy. Although chemo-radiation therapy has been recognized as one of the standard therapies for gastric cancer in Western countries, radiation therapy was selected in Japan for palliation therapy of recurrent disease or a terminal cancer to improve patients' QOL. On the other hand, we demonstrated in our trial of chemo-radiation therapy with S-1/low-dose CDDP/radiation (TSLDR), which was applied to initial treatment against highly advanced Stage IV gastric cancer and revealed the usefulness of the regimen in anticancer effect and toxicity. In addition, chemo-radiation therapy including novel anticancer agents like S-1 will be discussed based on various kinds of view points, expecting a better clinical outcome of multimodal therapies against advanced gastric cancer.

Most patients who experience gastric volvulus present with mild or intermittent gastric obstructive symptoms. However, severe acute gastric volvulus can result in complete gastric outlet obstruction and ischemia. Consequently, acute gastric volvulus warrants immediate evaluation and management. The goals of management are to relieve the obstruction and prevent recurrent volvulus. Techniques to manage gastric volvulus depend on patient characteristics and the presence of gastric ischemia. In the absence of gastric ischemia, gastric volvulus can be managed with anterior abdominal wall gastropexy or paraesophageal hernia repair. If gastric ischemia is present, operative resection of the affected portion of the stomach is indicated. When operative management is indicated, many patients with gastric volvulus can be managed with minimally invasive (laparoscopic, endoscopic, or laparoendoscopic techniques.

    Purpose: Prospectively designed randomized clinical study was undertaken to assess the efficacy of simultaneous application of irradiation, Mitomycin C, and Bleomycin in treatment of patients with inoperable head and neck carcinoma. Methods and Materials: Between March 1991 and October 1993, 49 patients with inoperable head and neck carcinoma were randomly assigned to receive either radiation therapy alone (group A) or radiotherapy combined with simultaneous application of Mitomycin C and Bleomycin (group B). Patients in both groups were irradiated five times weekly with 2 Gy to the total dose of 66-70 Gy. Chemotherapy regimen included intramuscular application of Bleomycin 5 units twice a week, with the planned dose being 70 units and Mitomycin C 15 mg/m 2 applied intravenously after delivery of 9-10 Gy of irradiation. The application of Mitomycin C was planned to be repeated on last day of radiotherapy in the dose of 10 mg/m 2 . In attempt to enhance the effect of chemotherapeutic drugs, patients in group B received also Nicotinamide, Chlorpromazine, and Dicoumarol. Results: The difference in complete response rate between both treatment groups (24% in group A and 63% in group B) was statistically significant (p = 0.015). The difference in response rate was much more pronounced in patients with oropharyngeal carcinoma only (18% in group A compared to 81% in group B; p = 0.0003), while for all other subgroups added together, there was observed no benefit of multidrug therapy. Median follow-up was 18 months. Disease-free survival of patients in group A (9%) was significantly lower then in group B (48%) (p 0.001). The difference between both treatment groups was even greater in patients with oropharyngeal carcinoma only: disease-free survival of these patients in group B was 66%, while in group A, all recurred (p = 0.00001). Conclusion: From results of our prospective randomized study it seems that the group of patients that received multidrug treatment with

This study aims to examine survival outcomes in elderly patients with inoperable stage I NSCLC treated with SBRT.Methods: A total of 31 patients with single lesions treated with fractionated SBRT from 2008 to 2011 were retrospectively analyzed. A median prescribed dose of 48 Gy was delivered to the prescription isodose line, over a median of four treatments. The median biologically effective dose (BED was 105.6 (range 37.50–180, and the median age was 73 (65–90 years. No patient received concurrent chemotherapy.Results: With a median follow up of 13 months (range, 4–40 months, the actuarial median overall survival (OS and progression-free survival (PFS were 32 months, and 19 months, respectively. The actuarial median local control (LC time was not reached. The survival outcomes at median follow up of 13 months were 80%, 68%, and 70% for LC, PFS, and OS, respectively. Univariate analysis revealed a BED of >100 Gy was associated with improved LC rates (P = 0.02, while squamous cell histology predicted for worse LC outcome at median follow up time of 13 months (P = 0.04. Increased tumor volume was a worse prognostic indicator of both LC and OS outcomes (P < 0.05. Finally, female gender was a better prognostic factor for OS than male gender (P = 0.006. There were no prognostic indicators of PFS that reached

    Purpose: The radiation therapy results for patients with inoperable non-small-cell lung cancer (NSCLC) have been disappointing. Tumor dose escalation using concomitant boost technique (CBT) has been shown to improve local control in a few prospective studies. This trial was carried out to prospectively assess the radiation response and acute toxicity of CBT in comparison to the conventional treatment technique (CTT). Methods and Materials: Ninety-seven consecutive eligible patients were entered in this prospective clinical trial between November 1994 and February 1998. Patients were randomized to receive either CBT (43 patients) or CTT (54 patients) radiation therapy. These patients either refused chemotherapy or were judged as unsuitable for chemotherapy. Patients in the CBT group received 46.8 Gy in 26 fractions using large fields that encompassed the gross and occult disease. A concomitant boost of 18.2 Gy (0.7 Gy per fraction) was delivered to the gross disease using small fields with 1.5-cm margins. The small fields were treated concurrently with the large fields and the total dose to the tumor area was 65 Gy in 26 fractions. Patients in the CTT group received 70.8 Gy in 38 fractions. The acute toxicity between each group was compared. The response rate was analyzed and compared by treatment group, gender, age, stage, histology, initial Karnofsky performance score (KPS), severity of acute toxicity, and maximum body weight loss (MBWL) during treatment course. Results: The demographic parameters such as sex, age, and stage were evenly distributed in each treatment group. The majority of these patients had Stage IIIA and IIIB disease. Overall median treatment times were 39 days for the CBT group of patients and 62 days for the CTT group. No treatment-related mortality was found. There were 2 patients in the CTT group with acute RTOG Grade 3 lung toxicity, and no Grade 3 lung or esophageal toxicity was observed in CBT group. The response rates, assessed by

    Head and neck paragangliomas (HNPGLs) are rare tumours arising from autonomic nervous system ganglia. Although surgery offers the best chance of complete cure, there is associated morbidity due to the crucial location of these tumours. Radiotherapy arrests tumour growth and provides symptomatic improvement, but has long-term consequences. These tumours express somatostatin receptors (SSTR) and hence peptide receptor radionuclide therapy (PRRT) is now a treatment option. We assessed the molecular, morphological and clinical responses of inoperable HNPGLs to PRRT. Nine patients with inoperable HNPGL assessed between June 2006 and June 2014 were included. Four patients had a solitary lesion, four had multifocal involvement and one had distant metastases (bone and lungs). The patients were treated with PRRT using 90 Y/ 177 Lu-labelled peptides after positive confirmation of SSTR expression on 68 Ga-DOTATOC PET/CT. All patients received two to four courses of PRRT. Subsequent serial imaging with 68 Ga-DOTATOC PET/CT was carried out every 6 months to assess response to treatment. Clinical (symptomatic) response was also assessed. Based on molecular response (EORTC) criteria, four of the nine patients showed a partial molecular response to treatment seen as significant decreases in SUV max , accompanied by a reduction in tumour size. Five patients showed stable disease on both molecular and morphological criteria. Six out of nine patients were symptomatic at presentation with manifestations of cranial nerve involvement, bone destruction at the primary site and metastatic bone pain. Molecular responses were correlated with symptomatic improvement in four out of these six patients; while two patients showed small reductions in tumour size and SUV max . The three asymptomatic patients showed no new lesions or symptomatic worsening. PRRT was effective in all patients, with no disease worsening seen, either in the form of neurological symptoms or distant spread. Though these

    Purpose: To evaluate the role of definitive radiation therapy (RT) in the treatment for medically inoperable patients with stage I-II non-small cell lung cancer (NSCLC). Materials and Methods: From 1976 through 1989, 84 patients with clinical stage I and II NSCLC were treated with definitive RT alone at Gunma University hospital. All patients were treated with 10 MV X-rays using antero-posterior parallel opposed fields. The total dose ranged from 60 Gy to 90 Gy (35 pts; 60-69 Gy, 39 pts; 70-74 Gy, 10 pts; ≥ 80 Gy) with once-daily standard fractionation. Results: The two and five-year survival rates were 74% and 31% for 28 patients with stage I disease, as compared with 40% and 19% for 56 patients with stage II respectively (p<0.05). Although there was no significant difference of survival rates by the histologic subtypes, in the patients with squamous cell carcinoma there were more long-term survivors. Fifty-three patients with tumors less than 5 cm in diameter had an infield progression rate of 14% at two years, in comparison with 38% of 31 patients with tumors greater than 5 cm (p<0.05). Overall distant failure occurred in 57% of the patients with smaller tumors and in 80% of the patients with larger tumors (p<0.05). The difference of survival rates for these two groups was statistically significant (p<0.005). Ten patients given a total dose of 80Gy or over had only 17% local progression at the time of last follow-up, however they had not been alive beyond three years because they developed pulmonary insufficiency due to severe stenosis of the proximal bronchus. For age and sex, there were no significant differences in survival, however, patients with performance status of 0-1 lived longer than those with a status of 2 or more (MST 24 versus 13 months; p=0.06). Conclusion: The tumor size was the most important factor not only for local control but also for distant failure. It was also suggested that the optimal radiation dose for medically inoperable stage I

    Malignant gastric outlet obstruction represents a terminal stage in pancreatic cancer. Between 5% and 25% of patients with pancreatic cancer ultimately experience malignant gastric outlet obstruction. The aim in palliating patients with malignant gastric outlet obstruction is to reestablish an oral intake by restoring gastrointestinal continuity. This ultimately improves their quality of life in the advanced stages of cancer. The main drawback to operative bypass is the high incidence of delayed gastric emptying, particularly in this group of patients with symptomatic obstruction. This study aimed to compare surgical gastrojejunostomy and endoscopic stenting in palliation of malignant gastric outlet obstruction, acknowledging the diversity and heterogeneity of patients with this presentation. This retrospective study investigated patients treated for malignant gastric outlet obstruction from December 1998 to November 2008 at Nepean Hospital, Sydney, Australia. Endoscopic duodenal stenting was performed under fluoroscopic guidance for placement of the stent. The operative patients underwent open surgical gastrojejunostomy. The outcomes assessed included time to diet, hospital length of stay (LOS), biliary drainage procedures, morbidity, and mortality. Of the 45 participants in this study, 26 underwent duodenal stenting and 19 had operative bypass. Comparing the stenting and operative patients, the median time to fluid intake was respectively 0 vs. 7 days (P < 0.001), and the time to intake of solids was 2 vs. 9 days (P = 0.004). The median total LOS was shorter in the stenting group (11 vs. 25 days; P < 0.001), as was the median postprocedure LOS (5 vs. 10 days; P = 0.07). Endoscopic stenting is preferable to operative gastrojejunostomy in terms of shorter LOS, faster return to fluids and solids, and reduced morbidity and in-hospital mortality for patients with a limited life span.

    The S100 protein family comprises 22 members whose protein sequences encompass at least one EF-hand Ca 2+ binding motif. They were involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. However, the expression status of S100 family members in gastric cancer was not known yet. Combined with analysis of series analysis of gene expression, virtual Northern blot and microarray data, the expression levels of S100 family members in normal and malignant stomach tissues were systematically investigated. The expression of S100A3 was further evaluated by quantitative RT-PCR. At least 5 S100 genes were found to be upregulated in gastric cance by in silico analysis. Among them, four genes, including S100A2, S100A4, S100A7 and S100A10, were reported to overexpressed in gastric cancer previously. The expression of S100A3 in eighty patients of gastric cancer was further examined. The results showed that the mean expression levels of S100A3 in gastric cancer tissues were 2.5 times as high as in adjacent non-tumorous tissues. S100A3 expression was correlated with tumor differentiation and TNM (Tumor-Node-Metastasis) stage of gastric cancer, which was relatively highly expressed in poorly differentiated and advanced gastric cancer tissues (P < 0.05). To our knowledge this is the first report of systematic evaluation of S100 gene expressions in gastric cancers by multiple in silico analysis. The results indicated that overexpression of S100 gene family members were characteristics of gastric cancers and S100A3 might play important roles in differentiation and progression of gastric cancer

    Conclusion: We identify male gender, weight loss greater than 10% and age as independent prognostic factors for patients treated with medically inoperable NSCLC treated with SABR or hypofractionated radiotherapy. Based on our survival models, age alone can be used interchangeably with aCCI or CCI plus age with the same prognostic value. Age is more reliably recorded, less prone to error and therefore a more useful metric than Charlson score in this group of patients.

    Radiation therapy plays an integral role in the treatment of gastric cancer in the postsurgery setting, the inoperable/palliative setting, and, as in the case of the current report, in the setting of neoadjuvant therapy prior to surgery. Typically, anterior-posterior/posterior-anterior (AP/PA) or 3-field techniques are used. In this report, we explore the use of intensity-modulated radiotherapy (IMRT) treatment in a patient whose care was transferred to our institution after 3-field radiotherapy (RT) was given to a dose of 30 Gy at an outside institution. If the 3-field plan were continued to 50 Gy, the volume of irradiated liver receiving greater than 30 Gy would have been unacceptably high. To deliver the final 20 Gy, an opposed parallel AP/PA plan and an IMRT plan were compared to the initial 3-field technique for coverage of the target volume as well as dose to the kidneys, liver, small bowel, and spinal cord. Comparison of the 3 treatment techniques to deliver the final 20 Gy revealed reduced median and maximum dose to the whole kidney with the IMRT plan. For this 20-Gy boost, the volume of irradiated liver was lower for both the IMRT plan and the AP/PA plan vs. the 3-field plan. Comparing the IMRT boost plan to the AP/PA boost-dose range ( 10 Gy) in comparison to the AP/PA plan. The IMRT boost plan also irradiated a smaller volume of the small bowel compared to both the 3-field plan and the AP/PA plan, and also delivered lower dose to the spinal cord in comparison to the AP/PA plan. Comparison of the composite plans revealed reduced dose to the whole kidney using IMRT. The V20 for the whole kidney volume for the composite IMRT plan was 30% compared to approximately 60% for the composite AP/PA plan. Overall, the dose to the liver receiving greater than 30 Gy was lower for the composite IMRT plan and was well below acceptable limits. In conclusion, our study suggests a dosimetric benefit of IMRT over conventional planning, and suggests an important role for

    The Database of Human Gastric Cancer (DBGC) is a comprehensive database that integrates various human gastric cancer-related data resources. Human gastric cancer-related transcriptomics projects, proteomics projects, mutations, biomarkers and drug-sensitive genes from different sources were collected and unified in this database. Moreover, epidemiological statistics of gastric cancer patients in China and clinicopathological information annotated with gastric cancer cases were also integrated into the DBGC. We believe that this database will greatly facilitate research regarding human gastric cancer in many fields. DBGC is freely available at http://bminfor.tongji.edu.cn/dbgc/index.do PMID:26566288

    Cross-sectional gastric antral area (GAA) measurements by ultrasonography (US) have been proposed for preoperative assessment of gastric volume in adults but not been validated in children. This study investigates whether in children gastric volumes can be predicted by US performed in different patient positions. Gastric fluid and air volumes were examined by magnetic resonance imaging before or up to 120 min after ingestion of 7 ml·kg(-1) diluted raspberry syrup in healthy volunteers who had fasted overnight. GAA was measured with US three times each in supine (SUP), elevated 45° degree supine (E45) and right decubital (RDC) position using imaging planes defined by vascular landmarks. Correlation coefficients (Pearson) between GAA and gastric volumes were calculated and Bland-Altman analysis performed. Sixteen children aged from 6.4 to 12.8 (9.2) years were included in 23 examinations: 6 after overnight fasting, 3 directly after, and 14 with a delay of 74 ± 35 min after fluid intake. GAA was 221 ± 116, 218 ± 112, and 347 ± 188 mm(2) for SUP, E45, and RDC position, respectively. The best correlation between body weight corrected total gastric/gastric fluid volume (TGV(w)/GFV(w)) with GAA was found for RDC position (R = 0.79; P < 0.01/R = 0.78; P < 0.01). Bias and precision of calculated and measured GFV(w) was 0 ± 2.8 ml·kg(-1). Correlations between GAA and TGV(w) or GFV(w) in children are best in the RDC position, but not sufficient to predict GFV(w) with a given GAA. Interpretation of isolated GAA values may be misleading. © 2011 Blackwell Publishing Ltd.

    Introduction: Comprehensive staging laparotomy and cytoreductive surgery followed by chemotherapy has been the standard of care in advanced ovarian cancer. Neoadjuvant chemotherapy is an alternative in inoperable advanced cases. To select patients amenable for successful cytoreduction, major determinants including CT imaging and laparoscopy could be of value. There is no general accepted model for selection and reproducibility of techniques are a major challenge due to different clinical prac...

    Purpose: To evaluate in a retrospective review the role of proton beam therapy for patients with medically inoperable Stage I non-small-cell lung cancer (NSCLC). Patients and Methods: From November 2001 to July 2008, 55 medically inoperable patients with Stage I NSCLC were treated with proton beam therapy. A total of 58 (T1/T2, 30/28) tumors were treated. The median age of study participants was 77 years (range, 52-86 years). A total dose of 66 GyE in 10 fractions was given to peripherally located tumors and 72.6 GyE in 22 fractions to centrally located tumors. Results: The rates (95% confidence interval) of overall and progression-free survival of all patients and of local control of all tumors at 2 years were 97.8% (93.6-102.0%), 88.7% (77.9-99.5%), and 97.0% (91.1-102.8%), respectively. There was no statistically significant difference in progression-free rate between T1 and T2 tumors (p = 0.87). Two patients (3.6%) had deterioration in pulmonary function, and 2 patients (3.6%) had Grade 3 pneumonitis. Conclusion: Proton beam therapy was effective and well tolerated in medically inoperable patients with Stage I NSCLC.

    Malignant gastric outlet obstruction is a late complication of intraabdominal malignancy. Self-expandable metallic stent placement has been a safe palliative treatment to relieve obstructive symptoms. We aimed to assess the efficacy and safety of metallic stents in our patients and analyzed the clinical outcome of different brands. Seventy-one patients with inoperable gastric outlet obstruction receiving WallFlex enteral stents (WallFlex group) or Bonastents (Bonastent group) since April 2010 were analyzed retrospectively. The overall technical and clinical success rates of stent placement were 100% and 93%, respectively. The baseline characteristics and clinical outcomes including procedure-related complications, restenosis, and reintervention rates were comparable between the 2 groups. However, the Bonastent group had a higher rate of stent fracture than the WallFlex group (13.3% vs 0%, P = 0.03). The mean duration of overall stent patency was 132.7 days. The mean duration of survival was 181.9 days. Resumption of regular diet or low residual diet at day 7 after stent insertion predicted stent patency (haza
