Background A regimen of epirubicin, cisplatin, and infused fluorouracil (ECF) improves survival among patients with incurable locally advanced or metastatic gastric adenocarcinoma. We assessed whether the addition of a perioperative regimen of ECF to surgery improves outcomes among patients with potentially curable gastric cancer. Methods We randomly assigned patients with resectable adenocarcinoma of the stomach, esophagogastric junction, or lower esophagus to either perioperative chemotherapy and surgery (250 patients) or surgery alone (253 patients). Chemotherapy consisted of three preoperative and three postoperative cycles of intravenous epirubicin (50 mg per square meter of body-surface area) and cisplatin (60 mg per square meter) on day 1, and a continuous intravenous infusion of fluorouracil (200 mg per square meter per day) for 21 days. The primary end point was overall survival. Results ECF-related adverse effects were similar to those previously reported among patients with advanced gastric cancer. Rates of postoperative complications were similar in the perioperative-chemotherapy group and the surgery group (46 percent and 45 percent, respectively), as were the numbers of deaths within 30 days after surgery. The resected tumors were significantly smaller and less advanced in the perioperative-chemotherapy group. With a median follow-up of four years, 149 patients in the perioperative-chemotherapy group and 170 in the surgery group had died. As compared with the surgery group, the perioperative-chemotherapy group had a higher likelihood of overall survival (hazard ratio for death, 0.75; 95 percent confidence interval, 0.60 to 0.93; P = 0.009; five-year survival rate, 36 percent vs. 23 percent) and of progression-free survival (hazard ratio for progression, 0.66; 95 percent confidence interval, 0.53 to 0.81; P<0.001). Conclusions In patients with operable gastric or lower esophageal adenocarcinomas, a perioperative regimen of ECF decreased tumor size and stage and significantly improved progression-free and overall survival.

Prevention of Venous Thromboembolism* American College of Chest Physicians Evidence- Based Clinical Practice Guidelines (8th Edition)

Sepsis is the leading cause of death in critically ill patients in the United States. Yet the individual host response to septicemia is variable, depending on the patient's immune response, age, nutritional status, and coexisting conditions, as well as on the virulence of the organism and the size of the inoculum. This review examines evolving concepts of sepsis and discusses new and potential therapies. Recent clinical advances include therapy with activated protein C, stringent control of blood glucose, and early goal-directed therapy to treat cellular oxygen deficit. Future therapies may be focused on modulating the immune response in the light of the characteristics of the specific pathogen, the genetic profile of the patient, and the duration of the disease.

The pathophysiology and treatment of sepsis.

The purpose of this article is to review the status and limitations of anatomic tumor response metrics including the World Health Organization (WHO) criteria, the Response Evaluation Criteria in Solid Tumors (RECIST), and RECIST 1.1. This article also reviews qualitative and quantitative approaches to metabolic tumor response assessment with 18 F-FDG PET and proposes a draft framework for PET Response Criteria in Solid Tumors (PERCIST), version 1.0. Methods: PubMed searches, including searches for the terms RECIST, positron, WHO, FDG, cancer (including specific types), treatment response, region of interest, and derivative references, were performed. Abstracts and articles judged most relevant to the goals of this report were reviewed with emphasis on limitations and strengths of the anatomic and PET approaches to treatment response assessment. On the basis of these data and the authors’ experience, draft criteria were formulated for PET tumor response to treatment. Results: Approximately 3,000 potentially relevant references were screened. Anatomic imaging alone using standard WHO, RECIST, and RECIST 1.1 criteria is widely applied but still has

From RECIST to PERCIST: Evolving Considerations for PET Response Criteria in Solid Tumors

Prevention of Venous Thromboembolism : The Seventh ACCP Conference on Antithrombotic and Thrombolytic Therapy

In a prospective study 250 patients with proven cholelithiasis and clinical, biochemical and ultrasound indications for laparoscopic cholecystectomy (LC) underwent endoscopic retrograde cholangiography (ERCP) and (if bile-duct stones had been shown) endoscopic papillotomy (EPT). The biliary system was demonstrated in 229 patients (91.6%). Biliary tract stones were confirmed in 18 of 68 patients in whom they had been suspected clinically. In addition, ERCP revealed small stones in the bile-duct in eight of 154 patients with normal biochemical results and unremarkable ultrasound imaging, and in seven patients bile-duct anomalies which required EPT or open cholecystectomy. However, in retrospect five of the patients with cystic duct anomalies could have been treated by LC. The complication rate of ERCP/EPT was 3.2%. It is concluded from these results that, in view of the cost and potential risk to the patient, ERCP before LC can be limited to patients suspected of having bile-duct stones, even though small stones may be missed.

Laparoskopische Cholezystektomie: ERCP als präoperative Standarddiagnostik?

Klammernahtgerate werden in nahezu allen Bereichen der gastroenterologischen Chirurgie als Alternative zur Handnaht angewendet. Die Indikationen zur Staplernaht werden jedoch kontrovers diskutiert [1, 3, 6, 30, 39, 43]. Ausgesprochene Protagonisten der Klammernahtgerate fuhren nahezu samtliche Nahte am Gastrointestinaltrakt mit Staplern aus, wahrend konservativ eingestellte Chirurgen nach wie vor ausschlieslich die Handnaht verwenden. Die meisten Chirurgen benutzen beide Nahtmethoden parallel und setzen den Stapler nur fur solche Operationsschritte ein, bei denen er besonders geeignet erscheint.

Stapler am Gastrointestinaltrakt — pro und contra

Lokoregionale Rezidive stellen ein relevantes Problem in der chirurgischen Onkologie dar. Intraluminale Lokalrezidive sind in vielen Fallen Ausdruck einer unzureichenden Primarresektion, die mit nicht ausreichenden Sicherheitsabstanden durchgefuhrt wurde. Die Nachresektion mit ausreichenden Sicherheitsabstanden stellt, wann immer moglich, das Therapieverfahren der Wahl dar. Das Auftreten eines Rezidivs im Tumorbett ist nach optimaler primarer Resektion Ausdruck einer bereits primar lokal weit fortgeschrittenen Erkrankung. Die Indikation zur Nachresektion ist hier immer sehr kritisch abzuwagen. Aussicht auf langerfristige Tumorkontrolle besteht nur, wenn die Zweitresektion residualtumorfrei durchgefuhrt werden kann und wenn sie sinnvoll in ein multimodales Behandlungskonzept eingebettet ist. Fur Rezidive im Bereich der Lymphabstrombahn, der sog. 4. Dimension, besteht in der Regel keine zweite kurative Behandlungsoption.

Background:

Gastro-oesophageal reflux disease (GORD) is a commonly underestimated aetiological factor in patients with respiratory symptoms. In this study, acid reflux in healthy volunteers and patients with GORD with and without respiratory symptoms was investigated by dual pH monitoring.



Methods:

Thirty healthy volunteers and 43 patients with GORD underwent oesophageal manometry and dual pH monitoring with one probe in the proximal and one in the distal oesophagus. Nineteen of the 43 patients complained of respiratory symptoms.



Results:

There were no differences in proximal probe measurements between volunteers and patients without respiratory symptoms. Patients with GORD and respiratory symptoms had a higher prevalence of abnormally high exposure to gastric juice and more reflux episodes in the proximal oesophagus compared with patients with GORD and no respiratory symptoms. Some 17 of 19 patients with GORD and respiratory symptoms showed deteriorated oesophageal body motility.



Conclusion:

Dual pH monitoring is feasible and well tolerated, and provides an objective means of evaluating patients with GORD and respiratory symptoms. Prolonged exposure of the proximal oesophagus to gastric juice and disorders of oesophageal body motility seem to be responsible for the development of respiratory symptoms.

Assessment of respiratory symptoms with dual pH monitoring in patients with gastro-oesophageal reflux disease

The frequency and prognostic relevance of sarcoid-like lesions and microcarcinosis in regional lymph nodes in gastric cancer (n = 113; pT1-3, pN0-1, pM0, R0) were investigated; the prognostic value was compared with pT and pN stage, grading and Lauren's tumor classification with Cox's multivariate regression-model. Sarcoid like lesions were found in 34% of the cases (n = 113). Statistical analysis did not indicate that they had any prognostic value or showed whether or not microcarcinosis or metastasis was present; they were independent of pT stage, histological tumor type, tumor grading, and the clinical course of disease. Microcarcinosis (defined as scattered carcinoma cells within lymph node sinuses or pulp without adjacent stromal reaction) was revealed by immunohistochemistry in 90% of pN0 cases; the presence of 3 or more tumor cells per lymph node section in over 10% of sampled lymph nodes per case carried a significant prognostic value. In microcarcinosis without evidence of metastasis, the number of tumor cells and the number of involved lymph nodes are of prognostic value. In pN1 cases microcarcinosis was found as well as the metastases in 97% and had no additional prognostic value. Microcarcinosis alone has a different significance from lymph node metastasis for prognosis.
