[Autoimmune pancreatitis versus pancreatic cancer]. / Autoimmunpankreatitis versus Pankreaskarzinom.

CLINICAL ISSUE: Autoimmune pancreatitis (AIP) is classified as a distinct form of pancreatitis according to the guidelines. It is characterized by imaging morphologic and histologic features and is associated with extrapancreatic manifestations in type 1 IgG 4-associated disease. Symptoms and findings almost always improve with administration of steroids. Differentiation from pancreatic ductal adenocarcinoma is required, particularly in the presence of AIP with focal parenchymal involvement. STANDARD RADIOLOGIC PROCEDURES: If AIP is suspected, abdominal ultrasound and/or endosonography, computed tomography (CT), and preferably magnetic resonance imaging (MRI) are indicated. A distinction is made between parenchymal and ductal changes that specifically indicate the presence of AIP. METHODOLOGICAL INNOVATIONS AND EVALUATION: The diagnosis of autoimmune pancreatitis should be made based on the International Consensus Criteria (ICDC), in which the five main features (imaging, serology, histology, other organ involvement, response to steroid medication) are assessed. In type 1 AIP, typical imaging changes are sufficient to establish the diagnosis even with negative histology, whereas for type 2 AIP, histologic evidence is required. Imaging changes help in the differential diagnosis from pancreatic cancer. PRACTICAL RECOMMENDATIONS: The following article addresses and evaluates crucial imaging diagnostic CT and MRI criteria for correct classification of findings, description of results, and differentiation of autoimmune pancreatitis from pancreatic cancer.

[Incidental and leave me alone findings of abdominal organs-part 2 : Spleen, kidneys and adrenal glands and efferent urinary tracts]. / Inzidentelle und Leave-me-alone-Befunde der abdominellen Organe ­ Teil 2 : Milz, Niere und Nebennieren sowie ableitende Harnwege.

For masses of the spleen, which are mostly benign, accessory spleens, cysts and hemangiomas should be radiologically described; however, if confirmed further follow-up control is unnecessary. In the case of disseminated small masses, chronic inflammation and granulomatous diseases, such as tuberculosis and sarcoidosis should be considered in the differential diagnostics. Solid masses in the kidneys should always be further clarified, with the exception of a fat-rich angiomyolipoma. For cystic masses of the kidneys, the modified Bosniak classification for computed tomography or magnetic resonance imaging should be used. Masses of the adrenal glands greater than 10mm in size should be clarified further as well as those where fat is not detected, independent of the size and evidence of malignancy.

[Incidental and "leave me alone" findings of abdominal organs-part 1 : Liver, gall ducts and pancreas]. / Inzidentelle und Leave-me-alone-Befunde der abdominellen Organe ­ Teil 1 : Leber, Gallenwege und Pankreas.

Incidentalomas of the parenchymal organs of the abdomen, i.e. radiological findings in these organs that are not the primary focus of the clinical question, are frequent in this region of the body. In particular, findings presumed to be unimportant, such as cystic masses in the liver, the bile duct system or the pancreas, initially appear to be irrelevant in the diagnosis. For the liver we define the mostly clearly diagnosable simple cysts and hemangiomas as leave me alone lesions. Otherwise, we recommend a classification of incidentalomas into the three major categories (<0.5 cm, 0.5-1.5 cm and >1.5 cm) as well as an assessment with respect to clearly benign and suspect imaging characteristics in the context of a classification of patients into three different risk groups.

[Diagnostic Imaging of pancreatic carcinoma-Update of the new guideline]. / Diagnostik beim Pankreaskarzinom ­ Update in der neuen Leitlinie.

The new German S3 guidelines on ductal pancreatic adenocarcinoma were published for the first time on the homepage of the Association of the Scientific Medical Societies in Germany (AWMF) in December 2021 as a new update and thus the second update (first update 2013) and contain a large number of innovations in terms of diagnostics and treatment. The guidelines were organized and led by the German Society for Digestive and Metabolic Diseases (DGVS). In this article we would like to present the central content and innovations related to the radiological diagnostics of ductal pancreatic adenocarcinoma. The most important innovations are the highest recommendation strength in favor of computed tomography (CT) when assessing tumor spread as well as the adaptation of the European guidelines for cystic tumors by magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP) as the method of first choice. A further innovation is the implementation of a structured reporting of CT findings for describing the anatomical tumor resectability on the basis of the publication presented by the Abdominal Imaging Working Group and the Oncological Imaging Working Group of the German Radiological Society. There is no evidence for the implementation of radiological imaging in the field of aftercare or in the field of screening.

[Incidental and "leave me alone" findings in the GI tract-part 1 : Intestinal lumen and intestinal wall]. / Inzidentelle und Leave-me-alone-Befunde des GI-Trakts ­ Teil 1 : Darmlumen und Darmwand.

CLINICAL PROBLEM: Due to the widespread use of computed tomography (CT) and magnetic resonance imaging (MRI) asymptomatic incidental findings of the gastrointestinal tract (GI) are increasingly being recognized. Incidental findings are frequently not part of the primary inquiry from referring physicians but it is obligatory to make a diagnosis and to stipulate the need for further clarification. RADIOLOGICAL STANDARD PROCEDURES: A multitude of incidental findings in the intestinal lumen, in the intestinal wall and in the adjacent mesenterium or subperitoneal space are shown in CT and MRI. METHODOLOGICAL INNOVATIONS AND ASSESSMENT: The first part of the two-part overview addresses the intestinal incidental findings in the lumen, such as coproliths, invaginations, mucoceles and chronic dilatations. In the intestinal wall, thickenings of neoplastic and nonneoplastic origins are discussed. Many of the findings can be classified as benign and as "leave me alone lesions" do not necessitate any further clarification but in contrast others need a definitive clarification. The most important incidental findings in the GI tract are systematically classified, illustrated and evaluated with respect to the clinical relevance, depending on the localization (e.g. stomach, small and large intestines).

[Incidental and "leave me alone" findings of the GI tract-part 2 : Intestinal wall and mesentery]. / Inzidentelle und Leave-me-alone-Befunde des GI-Trakts ­ Teil 2 : Darmwand und Mesenterium.

Due to the widespread use of computed tomography (CT) and magnetic resonance imaging (MRI) asymptomatic incidental findings of the gastrointestinal (GI) tract are increasingly being recognized. Incidental findings are frequently not part of the primary inquiry from referring physicians but it is obligatory to make a diagnosis and to stipulate the need for further clarification. A multitude of incidental findings in the intestinal lumen, in the intestinal wall and in the adjacent mesentery or subperitoneal space are shown in CT and MRI of the GI tract. The last part of the two-part review addresses the gastrointestinal incidental findings in the intestinal wall and the adjacent sections. Extramural incidental findings occur as mesenteric inflammation, tumors and cysts. Many of the findings can be classified as benign and as "leave me alone lesions" do not necessitate any further clarification but in contrast others need a definitive clarification. The most important incidental findings in the GI tract are systematically classified, illustrated and evaluated with respect to the clinical relevance, depending on the localization (e.g. stomach, small and large intestines).

[Acute pancreatitis : Typical findings in computed tomography and magnetic resonance imaging]. / Akute Pankreatitis : Typische Befunde in Computer- und Magnetresonanztomographie.

CLINICAL PROBLEM: Imaging plays a major role to differentiate interstitial edematous from necrotic pancreatitis and to describe relevant local complications for proper patient management and decision-making in acute pancreatitis. STANDARD RADIOLOGICAL PROCEDURES: The revised Atlanta classification 2012 of acute pancreatitis divides patients into mild, moderately severe and severe groups. Computed tomography (CT) and magnetic resonance imaging (MRI) are well established for diagnosis and follow-up of acute pancreatitis and its complications METHODOLOGICAL INNOVATIONS AND ASSESSMENT: Based on the revised Atlanta classification, CT and MRI allow for adequate categorization of interstitial edematous and necrotic pancreatitis. Imaging and standardized reporting nomenclature enable confident differentiation of early and late complications in acute pancreatitis. RECOMMENDATIONS: The aim of this review article is to present an image-rich overview of different morphologic characteristics of acute pancreatitis and associated local complications by CT or MRI using case examples.

[Guideline-based diagnosis of pancreatitis]. / Leitliniengerechte Diagnostik der Pankreatitis.

BACKGROUND: There is currently no S3 guideline that contains statements on the diagnosis and treatment of acute, chronic and autoimmune pancreatitis in a single guideline. OBJECTIVES: This article presents the most relevant recommendations relating to radiological imaging from the new "S3 guideline for pancreatitis". MATERIALS AND METHODS: The guideline was developed by the DGVS (German Society for Digestive and Metabolic Diseases). After an online-based Delphi survey, the statements were discussed by an interdisciplinary expert team at a 3-day consensus conference and then agreed upon. The level of evidence scheme (version 2) of the Oxford Centre for Evidence-based Medicine was used. RESULTS: The new German "S3 guideline pancreatitis" comprises for the first time all entities of pancreatitis, acute, chronic and autoimmune pancreatitis and contains a large number of innovations with regard to diagnostic imaging and therapy. In addition to the evidence-based recommendations for diagnosis and therapy, a German-language glossary of the revised Atlanta classification on acute pancreatitis was adopted by consensus of the interdisciplinary guideline expert team. Furthermore, protocol recommendations for the performance of computed tomography (CT) are provided for the first time. In this article we introduce the key recommendations and innovations in the field of diagnostic radiologic imaging for acute, chronic and autoimmune pancreatitis. CONCLUSIONS: In the future, every radiologist should have deep knowledge of the recommended time intervals for radiological imaging in acute pancreatitis and know the German terms for the description of acute pancreatitis; furthermore they should be able to classify the morphologies to the appropriate stages.

[Criteria for resectability of pancreatic cancer and postoperative imaging]. / Resektabilitätskriterien beim Pankreaskarzinom und postoperative Bildgebung.

By improving the techniques of pancreatic surgery, the mortality and morbidity for pancreatic carcinoma could be significantly reduced. For radiologists a profound knowledge of the surgical techniques is of decisive importance. Based on this knowledge postoperative complications can be reliably uncovered and local recurrences can be detected at an early stage. The complications resulting from pancreatic surgery can be severe and often necessitate a radiological intervention. As pancreatic cancer itself is a severe disease with a poor 5­year survival, which can only be improved by an R0 resection, it is crucial to identify using imaging those patients who are primarily operable or who can potentially achieve an operable condition through neoadjuvant chemotherapy (borderline) and inoperable patients to avoid postoperative complications which would additionally weaken them and result in unnecessary delays in initiating palliative therapy. Thus, familiarity with the clinical criteria of resectability and also inoperability in pancreatic cancer nowadays represents an essential basic knowledge for every oncological radiologist.

[Hepatopancreaticobiliary diseases in IgG4-associated autoimmune diseases]. / Pankreatikohepatobiliäre Erkrankungen bei IgG4­assoziierten Autoimmunerkrankungen.

BACKGROUND: IgG4-related diseases are rare systemic multiorgan diseases and can thus affect any organ system. The incidence of diagnosis has significantly increased due to increasing awareness. OBJECTIVE: In the abdomen the hepatopancreaticobiliary system provides an essential organ system for the expression of IgG4-associated autoimmune diseases. The focus here is autoimmune pancreatitis type 1 but IgG4-associated sclerosing cholangitis and IgG4-associated hepatopathy, which can also occur in combination are less well-known. METHODS: Various mostly Asiatic, histologically-based diagnostic systems, such as HISORt or international consensus diagnostic criteria (ICDC) are available for the diagnostics of hepatopancreaticobiliary IgG4-related autoimmune diseases, in which imaging techniques playing an increasingly important role. RESULTS: In addition to generalized organ swelling further morphological and also functional imaging criteria have become increasingly well-known for autoimmune pancreatitis, such as late enhancement or the imaging response to steroid therapy. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERP) can provide valuable information for the diagnostics of IgG4-related diseases in the hepatopancreaticobiliary system. CONCLUSION: IgG4-related autoimmune diseases of the hepatopancreaticobiliary system are a rare group of diseases in which increasing knowledge of the radiological appearance also leads to an increasingly frequency of diagnosis. IgG4-related diseases must be distinguished from non-necrotizing pancreatitis and pancreatic cancer, which is often difficult but has significant therapeutic consequences for the patients.

Dual-Energy Perfusion-CT in Recurrent Pancreatic Cancer - Preliminary Results.

PURPOSE: To evaluate the diagnostic performance of dual energy (DE) perfusion-CT for the differentiation between postoperative soft-tissue formation and tumor recurrence in patients after potentially curative pancreatic cancer resection. MATERIAL AND METHODS: 24 patients with postoperative soft-tissue formation in the conventional regular follow-up CT acquisition after pancreatic cancer resection with curative intent were included prospectively. They were examined with a 64-row dual-source CT using a dynamic sequence of 34 DE acquisitions every 1.5 s (80 ml of iodinated contrast material, 370 mg/ml, flow rate 5 ml/s). Weighted average (linearly blended M0.5) 120kVp-equivalent dual-energy perfusion image data sets were evaluated with a body-perfusion CT tool (see above) for estimating blood flow, permeability, and blood volume. Diagnosis was confirmed by histological study (n = 4) and by regular follow-up. RESULTS: Final diagnosis was local recurrence of pancreatic cancer in 15 patients and unspecific postoperative tissue formation in 9 patients. The blood-flow values for recurrence tissue trended to be lower compared to postoperative tissue formation with 16.6 ml/100 ml/min and 24.7 ml/100 ml/min, respectively for weighted average 120kVp-equivalent image data, which was not significant (n.s.) (p = 0.06, significance level 0.05). Permeability- and blood-volume values were only slightly lower in recurrence tissue (n.s.). CONCLUSION: DE perfusion-CT is feasible in patients after pancreatic cancer resection and a promising functional imaging technique. As only a trend for lower perfusion values in local recurrence compared to unspecific postoperative alterations was found, the perfusion differences are not yet sufficient to differentiate between malignancy and unspecific postoperative alterations for this new technique. Further studies and technical improvements are needed to generate reliable data for this clinically highly relevant differentiation. KEY POINTS: • DE Perfusion CT is feasible in patients after pancreatic cancer resection.• While reliable differentiation of unspecific postoperative tissue formation from recurrent malignancy cannot be achieved yet, it is within reach.• DE Perfusion CT has the potential to overcome todays limitations of pure morphological diagnosis of recurrent pancreatic cancer.

[Pancreatitis: An update]. / Pankreatitis : Ein Update.

BACKGROUND: Acute and chronic pancreatitis are becoming increasingly more severe diseases in the western world with far-reaching consequences for the individual patient as well as the socioeconomic situation. This article gives an overview of the contribution of radiological imaging to the diagnostics and therapy of both forms of the disease. RESULTS: Acute pancreatitis can be subdivided into severe (20%) and mild manifestations. The diagnostics should be performed with computed tomography (CT) or magnetic resonance imaging (MRI) for assessing necrosis or potential infections only in severe forms of pancreatitis. In chronic pancreatitis transabdominal ultrasound should initially be adequate for assessment of the pancreas. For the differential diagnosis between pancreatic carcinoma and chronic pancreatitis, MRI with magnetic resonance cholangiopancreatography (MRCP) followed by an endoscopic ultrasound-guided fine needle aspiration is the method of choice. CONCLUSION: For the primary diagnosis for acute and chronic pancreatitis ultrasound examination is the modality of first choice followed by radiological CT and MRI with MRCP examinations.

Current Practice vs. Guideline Based Imaging in Abdominal Radiology in the German Speaking Area: Results of an Online Survey.

PURPOSE: The working group for abdominal imaging within the German Roentgen Society (DRG) performed an online survey amongst radiologist concerning the current status of techniques for abdominal imaging. The results of this survey were compared with the most recent guidelines. MATERIALS AND METHODS: We performed an online survey open for all members of the DRG during a 76-day period with 65 questions and an overall estimated time for finishing the questionnaire of 15 minutes concerning technical specifications for abdominal radiological imaging. The results were evaluated using descriptive statistics. RESULTS: 90 of all participants, who filled out the survey covering more than 80% of the questions, were included in the statistical evaluation. 27% of all participants were registered radiologists while 73% represented radiologists working in a hospital. Most participants worked in a managerial position. The participants gave detailed information regarding the radiological techniques used in dedicated organ systems (esophagus, stomach, pancreas, liver, small intestines, colon) regarding acquired contrast phases and oral and intravenous administration of contrast medium. CONCLUSION: The results confirm that most radiologists participating in this survey perform their examinations and choose their modalities in conformity with the current existing clinical guidelines. Because most clinical guidelines do not specify radiological examinations in detail, there is a noteworthy heterogeneity of the acquired contrast phases and major divergence in terms of technical parameters. Therefore a joint radiological effort should be initiated for developing and publishing updated radiological parameters for abdominal imaging. KEY POINTS: • In German speaking countries indications for abdominal radiological examinations are performed with a high compliance to published guidelines. • There is a significant heterogeneity regarding the acquisition of different contrast phases for parenchymal abdominal organs. • There is an urgent need to publish radiological recommendations and guidelines based on current radiological literature for radiological abdominal imaging.

A Review of Scientific Topics and Literature in Abdominal Radiology in Germany - Part 1: Gastrointestinal Tract.

UNLABELLED: The working group for abdominal and gastrointestinal diagnosis is a group of the German Radiological Society (DRG) focusing clinically and scientifically on the diagnosis and treatment of the gastrointestinal tract with all parenchymatous abdominal organs. In addition to the clinical and scientific further development of abdominal radiology, the education of radiologists within this core discipline of radiology is one of the major aims. In this article we give an up-to-date literature review of scientific radiological topics especially covered by German radiologists. This manuscript focuses on the most recent literature on the diagnosis of the stomach, small bowel, colon and rectum. The review with a focus on the most recent studies published by German radiologists concludes with a synopsis of mesenterial bleeding and ischemia followed by a critical appraisal of the current literature on conventional abdominal radiography. KEY POINTS: Based on recent literature and guidelines there is a change of paradigms regarding the diagnosis of esophagus and gastric cancer towards CT, which is considered equally to endosonography. For small bowel imaging in Crohn's disease ultrasound as well as MRI with a new focus on DWI are the most important imaging modalities scientifically. For colonic diagnosis virtual colonoscopy has replaced the conventional radiological methods. For staging of rectal carcinoma as well as for therapeutic stratification a high resolution MRI of the pelvis is of paramount interest. Multislice CT is considered the most important modality to assess mesenteric ischemia or bleeding.

A Review of Scientific Topics and Literature in Abdominal Radiology in Germany--Part 2: Abdominal Parenchymal Organs.

UNLABELLED: The working group for abdominal and gastrointestinal diagnosis is a group of the German Radiological Society (DRG) focusing clinically and scientifically on the diagnosis and treatment of the gastrointestinal tract as well as the parenchymal abdominal organs. In this article we give an up-to-date literature review of scientific radiological topics especially covered by German radiologists. The working group experts cover the most recent relevant studies concerning liver-specific contrast media with an emphasis on a new classification system for liver adenomas. Additionally studies regarding selective internal radiotherapy (SIRT) are reviewed. For the pancreas the most important tumors are described followed by an introduction to the most recently introduced functional imaging techniques. The manuscript concludes with some remarks on recent studies and concerning chronic pancreatitis as well as autoimmune pancreatitis. KEY POINTS: • Different subtypes of liver adenomas with different therapeutic consequences can be differentiated by MRI • Most recently published studies focus on liver imaging with extracellular liver specific contrast media as well as diffusion weighted imaging. They consider this new method having a high diagnostic potential. • For pancreatic neoplasm diagnosis diffusion--as well as perfusion--imaging is considered as a highly promising method.

A Single-center Experience on the Value of Pancreas Graft Biopsies and HLA Antibody Monitoring After Simultaneous Pancreas-Kidney Transplantation.

BACKGROUND: In simultaneous pancreas-kidney transplantation (SPKT), monitoring of the pancreas allograft is more complex than the kidney allograft due to difficulties in obtaining pancreas histology and weak clinical evidence supporting the role of donor-specific antibodies (DSA). METHODS: We performed a single-center retrospective analysis of all 17 SPKT recipients who underwent a total of 22 pancreas allograft indication biopsies from October 2009 to September 2012. Fifteen patients had at least 2 DSA measurements: pretransplantation and at the time of biopsy. RESULTS: All 7 patients (100%) with post-transplantation DSA-positivity (de novo: n = 6; persistent: n = 1) at biopsy had at least 1 rejection episode either of the pancreas (n = 4) or the kidney (n = 3), with 3 antibody-mediated rejections (AMR). In contrast, only 4 of 8 patients (50%) without post-transplantation DSA had evidence of rejection, with 1 AMR. Findings during pancreas allograft biopsy procedures led to a change of immunosuppressive therapy in 11 of 15 (73%) patients. Patient survival, graft survival, and function were not adversely affected by the presence of post-transplantation DSA. One major and 2 minor procedure-related complications occurred during the pancreas biopsies. CONCLUSIONS: In this small retrospective analysis, pancreas allograft histology provided the most therapeutically relevant information, rather than the kidney histology or DSA monitoring.

Surgery in oesophago-gastric cancer with metastatic disease: Treatment, prognosis and preoperative patient selection.

BACKGROUND: The role of surgical resection in metastatic oesophago-gastric adenocarcinomas (EGA) is not defined and regularly discussed in interdisciplinary tumour boards. Primary objective of this retrospective study was the outcome of patients after surgery. We additionally evaluated our preoperative prognostic score (PPS) based on tumour grading, clinical response to chemotherapy and presumed R-status. METHODS: 123 of 811 EGA patients were evaluated as cM1, either confirmed intraoperatively or by imaging. Response evaluation after chemotherapy was performed by endoscopy, CT-scan and histopathologically. The prospectively documented patient and outcome data were analysed retrospectively. RESULTS: 70 patients with adenocarcinoma of the oesophago-gastric junction and 53 patients with gastric cancer were included. The majority had one M1 site (n = 102). 72 received preoperative chemotherapy (CTx) and 51 underwent primary resection. 11 were explored without resection. 49/112 (40%) had multivisceral resections and 63/112 (56%) were completely resected (R0). 26/72 (36%) were clinical responders and 30 patients had a favourable PPS. Median survival was 20.0 months. Survival was significantly prolonged by resection, especially complete resection, and by preoperative CTx (all p = 0.001). Multivisceral resection, type or number of metastases, or primary tumour localization had no impact on survival. In patients undergoing preoperative CTx, clinical response and the PPS influenced survival significantly. In R0 resected patients, preoperative CTx, clinical response and the PPS remained prognostic. CONCLUSION: Primary resection without preoperative CTx is not appropriate for metastatic EGA. Subgroups of patients with a favourable PPS with response to CTx may be good candidates for surgical resection in metastatic oesophago-gastric cancer.

Targeted diagnostic magnetic nanoparticles for medical imaging of pancreatic cancer.

Highly aggressive cancer types such as pancreatic cancer possess a mortality rate of up to 80% within the first 6months after diagnosis. To reduce this high mortality rate, more sensitive diagnostic tools allowing an early stage medical imaging of even very small tumours are needed. For this purpose, magnetic, biodegradable nanoparticles prepared using recombinant human serum albumin (rHSA) and incorporated iron oxide (maghemite, γ-Fe2O3) nanoparticles were developed. Galectin-1 has been chosen as target receptor as this protein is upregulated in pancreatic cancer and its precursor lesions but not in healthy pancreatic tissue nor in pancreatitis. Tissue plasminogen activator derived peptides (t-PA-ligands), that have a high affinity to galectin-1 have been chosen as target moieties and were covalently attached onto the nanoparticle surface. Improved targeting and imaging properties were shown in mice using single photon emission computed tomography-computer tomography (SPECT-CT), a handheld gamma camera, and magnetic resonance imaging (MRI).

[Salvage surgery in esophageal cancer : Feasibility in patients after definitive radiochemotherapy (> 50 Gy)]. / Salvage-Chirurgie bei Ösophaguskarzinomen : Sinnvoll bei Patienten nach definitiver Radio(chemo)therapie (> 50 Gy)?

BACKGROUND: Salvage surgery as an additional therapy option is currently discussed for an increasing number of patients with esophageal cancer after definitive radio(chemo)therapy after tumor progression, recurrence or on explicit request of the patient. OBJECTIVES: The objective of this study was an analysis of the surgical option of salvage esophagectomy after definitive radiation in patients with esophageal cancer. Additionally the current literature on this topic was evaluated. MATERIAL AND METHODS: A total of 92 patients with esophageal cancer from a prospective database were included in this study who underwent esophagectomy either after neoadjuvant radio(chemo)therapy (< 50 Gy) or definitive radio(chemo)therapy (> 50 Gy) between 2002 and 2012. The analysis was performed retrospectively. RESULTS: The median survival of the two groups of patients was not significantly different after initial diagnosis with 24.2 months (95 % CI 0.0-51.93) for patients undergoing definitive radio(chemo)therapy and 30.7 months (95 % CI 9.3-52.2) for patients after neoadjuvant therapy (p = 0.96). Both patient groups showed no differences in pretherapeutic characteristics and response to radio(chemo)therapy. Postoperative complications and perioperative mortality were not different. DISCUSSION: Salvage esophagectomy is now an additional treatment option after definitive radio(chemo)therapy in patients with esophageal cancer. In preselected patients with tumor recurrence, progression or with a strong wish for surgical therapy, salvage surgery should be discussed in interdisciplinary tumor boards after exclusion of distant metastases.
