Aim. To analyse the 5-year survival rate of patients undergoing radical surgery for pancreatic ductal adenocarcinoma (PDAC) and to identify prognostic factors. Methods. A prospectively maintained database of 90 consecutive patients who underwent radical resection for PDAC was analysed. Survival was evaluated using the Kaplan-Meier method. Log-rank test and Cox regression analysis were used for the evaluation of prognostic factors. P values less than 0.05 were considered significant. Results. Mean age (± standard deviation) was 63.2±8.6 years (female 28.9% and male 71.1%). Tumour localisation was in the head in 76 (84.5%), multifocal in 3 (3.3%) and in the body/tail in 11 (12.2%). Pancreatic head resection was performed in 75 (83.3%), total pancreatectomy in 4 (4.4%) and distal pancreatectomy with splenectomy in 11 (12.2%), with standard lymphadenectomy. Venous resection was in 4 (4.4%). Thirty-day and in-hospital mortality occurred in 1 (1.1%), 90-day mortality was 3.3%. On univariate analysis absence of perineural and vascular invasion, stage, absence of lymph node infiltration and no need for transfusion were associated with improved overall survival. On multivariate analysis vascular invasion HR=3.137 (95%CI: 1.692-5.816; P = 0.0003) and postoperative complications HR=2. ; P = 0.008) were identified as significant independent predictors of survival. The five-year survival rate was 18.9%, with five-year recurrence-free survival of 16.7%. Conclusion. Vascular invasion and postoperative complications were independent prognostic factors after curative resections of pancreatic cancer in studied cohort.
Introduction: Malignant granular cell tumor (MGCT) of the esophagus is an extremely rare malignancy with a poor prognosis. Literature describing this condition is not sufficient, especially regarding long-term survival. Presentation of Case: A 52-year-old woman presented with dyspnea and slow onset dysphagia. The endoscopy, endoscopic ultrasound (EUS), bronchoscopy, and positron emission tomography (PET)/computed tomography (CT) supported the suspicion of esophageal gastrointestinal stromal tumor (GIST). Open wedge esophagectomy and tracheal resection were performed. The histology proved periodic acid-Schiff (PAS)-positive granules in epithelial cells, hyperchromatic nuclei and the positivity of Protein soluble in 100% ammonium sulfate (S-100), vimentin, neuron-specific enolase, laminin, and myelinic proteins. Local recurrence after 10 months required a two-phase esophagectomy with retrosternal gastroplasty. Bone, liver, and mediastinal metastases occurred 6 months later, with overall survival of 34 months. Discussion: Preoperative histological confirmation is often not reliable. Tracheal invasion increases the perioperative risk and the probability of an unsuccessful resection. Esophagectomy or radical R0 local resection is the only known curative therapy. Repeated resections may increase survival in case of locoregional recurrence. Radiotherapy has a potential for palliative care. Conclusion: Esophageal MGCT requires a detailed presentation including long-term survival. Early surgical removal of intramural esophageal neoplasms with potentially malignant features is highly recommended. Radical and/or repeated esophageal resections are the only known therapies with curative potential.
IntroductionRespiratory complications (RC) including respiratory failure and adult respiratory distress syndrome (ARDS) affect the outcomes of esophagectomy substantially. In order to decrease their incidence, identification of important features of RC is necessary.AimTo evaluate the incidence and risk factors of postoperative RC following hybrid esophagectomy.Material and methodsThe retrospective analysis of consecutive hybrid esophagectomies for malignancies (transhiatal laparoscopic or thoracoscopic resection and limited open reconstruction phase) assessed the incidence and outcomes of RC in relation to the patients’ age, ASA score, neoadjuvant therapy, type of surgical procedure, TNM stage, the incidence of anastomotic leak and Clavien-Dindo classification.ResultsTranshiatal laparoscopic (176, 81.9%) or thoracoscopic hybrid esophagectomy (39, 18.1%, conversion in 7 patients) was completed in 215 patients, 187 (87%) men and 28 (13%) women. Respiratory complications developed in 86 (40%) and severe respiratory failure or ARDS occurred in 29 (13.5%) patients. The overall in-hospital mortality was 7.4%, 30-day mortality 5.6% (RC 9, myocardial infarction 1, conduit necrosis 1), and 90-day mortality a further 1.8% (multiple organ failure, ARDS). The incidence of RC correlates significantly with ASA score II and III (p = 0.0002) and Clavien-Dindo grade 4 and 5 in severe RC (p < 0.0001). Furthermore, hospital stay (p < 0.0001) and mortality (p < 0.0001) were significantly increased in RC.ConclusionsThe results show a higher occurrence of RC in polymorbid patients and patients with severe complications according to the Clavien-Dindo classification. Adequate risk management including surgical technique and perioperative prophylaxis and therapy of RC should be studied and standardized.
Background: Endosonography-guided fine needle aspiration biopsy (EUS-FNA)-associated metachronous gastric seeding metastases (GSM) of pancreatic ductal adenocarcinoma (PDAC) represent a serious condition with insufficient evidence. Methods: Retrospective analysis of PDAC resections with a curative-intent, proven pathological diagnosis of PDAC, preoperative EUS-FNA and post-resection follow-up of at least 60 months. The systematic literature search of published data was used for the GSM growth evaluation using Pearson correlation and the linear regression analyses. Results: The inclusion criteria met 59/134 cases, 16 (27%) had retained needle tract (15 following distal pancreatectomy, 1 following pylorus-sparing head resection). In total, 3/16 cases (19%) developed identical solitary GSM (10–26th month following primary surgery) and were radically resected. A total of 30 published cases of PDAC GSM following EUS-FNA were identified. Lesion was resected in 20 distal pancreatectomy cases with complete information in 14 cases. A correlation between the metastasis size and time (r = 0.612) was proven. The regression coefficient b = 0.72 expresses the growth of 0.72 mm per month. Conclusions: The GSM represent a preventable and curable condition. A remarkably high number of GSM following EUS-FNA was identified, leading to follow-up recommendation of EUS-FNA sampled patients. Multimodal management (gastric resection, adjuvant chemotherapy) may prolong survival.
