Surgical Approach for Lung and Liver Metastasis One Incision, One Solution Klinik Oberwart, Österreich Einleitung/Background Malignant melanoma, as one of the most aggressive forms of skin cancer, tends to develop metastases, significantly deteriorating the prognosis in affected patients. Resection of pulmonary metastases from malignant melanoma show a 5-year survival rate of 33%. Resection of liver metastases in such patients is associated with a median survival of 27 months when R0 resection is feasible. This case report underscores the significance of careful treatment planning and present a revolutionary approach in a patient with malignant melanoma metastasized in two different cavities. Methoden/Methods The patient underwent a posterolateral thoracotomy on the right side, followed by an anatomical resection of the lung segment IV and an atypical resection in segment VII through a phrenotomy. The postoperative course remained uncomplicated, and the patient was discharged on the 10th postoperative day. Zusammenfassung/Conclusion Considerations for a surgical approach enable rapid oncological meaningful surgical treatment at advanced age with a single incision, one-time anesthesia, and uncomplicated postoperative course. Metastases from other organs as rare histological findings in thyroid surgery 1Department of Surgery, Ordensklinikum Linz, Austria; 2VYRAL Linz, Austria; 3Johannes Kepler University Linz, Medical Faculty, Linz, Austria Background Metastatic disease of the thyroid gland is a very rare site, only 2-3% of all suspected malignancies of the thyroid gland are metastases of other organs. However, autopsy studies show much higher numbers of up to 24%. The primary tumor is commonly located in the kidney, breast, lung or the digestive tract. Indication for thyroid surgery usually allows exact workup during preoperative evaluation and discrepancies from the preoperative histology are not very common. However, deviations in the postoperative diagnosis sometimes would have required different treatment regimens. Methods Retrospective analysis of patients recorded in EUROCRINE after thyroid surgery at the certified center of the Ordensklinikum Linz, Austria, between 2018 and 2023. Results 1480 patients were included. 6 patients showed metastasis of extrathyroidal cancer. The primary cancer locations were renal cell carcinoma (n=3), rectal cancer (n=1), liposarcoma (n=1) and MALT lymphoma (n=1). Thyroid surgery was performed safely with low complication rates (bleeding=1.1%, hypoparathyroidism=18.9(temporary) and 1.2% (permanent), RLN paralysis= 1.2% (temporary) and 0,4% (permanent).However, preferred treatment approach would have been different if the exact diagnosis would have been known beforehand in 0.4% of the unknown lesions from other organs. Conclusion Thyroid surgery is performed safely in specialized centers.However, it is necessary to raise awareness for this rare location of metastasis in patients that develop a thyroidal mass and especially for those that have a history of a prior malignancy, as the surgical resection of the metastasis might not be the treatment of choice in those cases with disseminated diseases. Interdisciplinary multivisceral resection in metastatic ovarian cancer Allgemein- und Viszeralchirurgie, Kepler Universitätsklinikum Linz, Österreich Einleitung/Background Ovarian cancer is the second most common gynecological cause of death. At first presentation 75% of patients show FIGO III/IV, already having abdominal metastases. In our clinic multivisceral resection is performed interdisciplinary nearly every week. Methoden/Methods This is a case report of a 60 year old woman, presenting with progresive peritoneal carcinomatosis in ovarian cancer FIGO IIIC. After staging (CT, endoscopy, ascites punction) diagnosis was confirmed with diagnostic laparoscopy and biopsy. Neoadjuvantive chemoimmunotherapy was started because R0 resection was not possible due to multivisceral infiltration of cancer. Debulking surgery was then planned. By laparotomy extensive multivisceral resection was performed (adhesiolysis, deperitonealisation, maior + minor omentectomy, hysterectomy, adnexectomy, rectum resection, right hemicolectomy, splenectomy, cholecystectomy, loop ileostomy). Ergebnisse/Results Macroscopically no tumor was left. Chemoimmunotherapy was completed and 5 months later the ileostoma was removed. Zusammenfassung/Conclusion Debulking surgery and multivisceral resection in ovarian cancer requires high surgical skills. Surgeons must be flexible and master the full range of visceral surgery. The prognostic impact of the recurrence distribution pattern following curative intended pancreatic cancer surgery 1Department of Surgery, Ordensklinikum Linz, Austria; 2Johannes Kepler University Linz, Medical Faculty, Linz, Austria; 3VYRAL, Linz, Austria Background Early relapse represents a major challenge in pancreatic cancer care. Up to now, little is known about the recurrence distribution pattern and its impact on time until relapse and its prognostic impact following curative intended pancreatic surgery. Methods 1456 pancreatic resections (702 (48.2%) pancreatic cancer) have been documented in the pancreatic registry of the Ordensklinikum Linz between 2001-2021. The site of recurrence distribution and its impact on prognosis has been evaluated retrospectively. Results Relapse following upfront surgery has been documented in 206 patients (29.3%). Site of first recurrence distribution: liver (35%), multiple sites (28.2%), local (14.1%), lung (8.7%), peritoneum (7.8%), lymph nodes (3.4%) and others (2.8%). Site of recurrence was of significant prognostic value (in months): lung (OS 45, DFS 17, SAR 18), local (OS 36, DFS 15), nodal (OS 30, DFS 16), multiple sites (OS 26, DFS 19), peritoneum (OS 22, DFS 13) and liver (OS 19, DFS 9, SAR 5). Chemotherapy improved survival in all subgroups, especially in nodal positive patients (+11 months), lung and liver only patients, but not in patients with local recurrence. Conclusion Recurrence in the liver was associated with the worst, whereas lung only was associated with the best prognosis. Site of relapse was not associated with TNM stage. Local recurrence was unaffected by neoadjuvant or adjuvant chemotherapy exposure, but neoadjuvant chemotherapy significantly reduced relapse in liver or lung. Survival is determined by the site of first recurrence but not by the total number of organs involved during the course of the disease. Surgical treatment of stomach cancer in Austria Universitätsklinik für Viszeral-, Allgemein- und Thoraxchirurgie, Salzburg, Österreich Einleitung/Background In 1997, Rabl et al published the state of surgical treatment of stomach cancer in Austria. Aim of this study is to assess the current state, and furthermore the changes in the last 25 years. Methoden/Methods We created an online survey, containing 32 questions about incidence, diagnostic, surgical treatment and postoperative complications in 2022. The survey was sent via the Austrian society for surgery to all general surgery departments. Ergebnisse/Results We received data from 12 of the 133 departments (9%). 180 patients, diagnosed with stomach cancer, were treated at surgical departments. The median age was 70,5 years. In all cases an esophagogastroduodenoscopy with histological diagnosis, a computed tomography and evaluation by multidisciplinary tumor board were performed. The TNM and Laurén classifications are used routinely. The WHO classification is used mostly, the cancer genome atlas hardly ever. 139 patients (77,2%) underwent surgery. 13 operations were performed per department (0 – 28). Most commonly gastrectomy, followed by subtotal gastrectomy. 24 patients (17,2%) needed extended resection (spleen, colon, etc.), 63,3% in 1997. Two stents were placed. Minimally-invasive procedures take place at 6 departments (50%), robotic-assisted surgery at 3 departments (25%). Surgical complications occurred in 10,8% of patients, in 23,7% in 1997. Mortality rate following resective surgery was 0,5% (8,8% in 1997). Data collection is without problem for 10 departments, 5-year survival rate is without problem for all departments. Zusammenfassung/Conlusion Extended resections, complications and mortality decreased. Minimally-invasive and robotic-assisted surgeries and endoscopic stent-placement were established. Data quality is limited by low response rate. Circulating tumor DNA (ctDNA) dynamics predict early response to treatment in mGEC after 2 weeks of systemic treatment 1Gastrointestinal Cancer Center, Linz, Austria; 2Department of Surgery, Ordensklinikum Linz, Austria; 3Johannes Kepler University Linz, Medical Faculty, Linz, Austria; 4Department of Diagnostic and Interventional Radiology, Ordensklinikum Linz, Austria; 5Laboratory for Molecular Genetic Diagnostics, Ordensklinikum Linz, Austria; 6Institute of Human Genetics, Medical University of Innsbruck, Austria; 7Department of Internal Medicine I for Hematology with Stem Cell Transplantation, Hemostaseology and Medical Oncology, Ordensklinikum Linz, Austria; 8VYRAL, Linz, Austria Einleitung/Background Metastasized gastroesophageal carcinoma (mGEC) is associated with a poor overall survival (OS) of approximately 4-10 months. Circulating tumor DNA (ctDNA) is emerging as a promising prognostic biomarker for predicting OS and relapse recently. However, until now there was little knowledge on serial ctDNA detection and its impact on relapse prediction and prognosis in mGEC. Methoden/Methods CtDNA detection (ddPCR) was obtained serially from 37 matched tissue (NGS) patients with GEC prior to systemic treatment and every two weeks thereafter until restaging (n=173 samples). Results have been correlated with response to treatment (restaging), overall survival (OS) and progression free survival (PFS). Ergebnisse/Results Pretherapeutic detection rate was 77.8%. A decline of ctDNA under 58% of the pretherapeutic value after 2 weeks of systemic treatment was accompanied with a sensitivity of 66.7 and specificity of 100%. Response to treatment assessment was correct in 54.2% (pretherapeutically pos./neg.), 85.7% (dynamics at week 2) and 85.7% (dynamics at week 4) respectively. In contrast to pretherapeutic ctDNA positivity (n.s, p=0.445), ctDNA dynamics to this cutoff was significantly associated with OS (4.1 (95% CI 2.1-6.1) vs. 13.6 (95% CI 10.4-16.6) months, p<0.000) and PFS (3.2 (1.9-4.5) vs. 9.5 (95% CI 5.5-13-5), p=0.001) after two weeks of treatment. Zusammenfassung/Conclusion CtDNA could be used for early evaluation of response to treatment (NACT/CTX) in the future, saving 83.3% of unevaluated treatment time and chemotoxicity of patients suffering from relapse in GEC and allowing early change of treatment with anticipated prognostic impact. Revolutionizing systemic treatment evaluation in GI cancer care: ctDNA as a unifiable biomarker to predict response to treatment after 2 weeks of chemotherapy at the same cut-off for GEC, PC and CRC 1Gastrointestinal Cancer Center, Linz, Austria; 2Department of Surgery, Ordensklinikum Linz, Austria; 3Johannes Kepler University Linz, Medical Faculty, Linz, Austria; 4Department of Diagnostic and Interventional Radiology, Ordensklinikum Linz, Austria; 5Laboratory for Molecular Genetic Diagnostics, Ordensklinikum Linz, Austria; 6Institute of Human Genetics, Medical University of Innsbruck, Austria; 7Department of Internal Medicine I for Hematology with Stem Cell Transplantation, Hemostaseology and Medical Oncology, Ordensklinikum Linz, Austria; 8VYRAL, Linz, Austria Background ctDNA has emerged as promising biomarker in gastrointestinal cancer. However, definition for detectability and cut-offs are reported very heterogeneously. We first in man evaluated response to treatment and correlation to actual volumetric tumor burden at a unifiable cut-off for dynamic changes during chemotherapy in 3 different major GI-cancer types (n=924 samples). Methods Liquid biopsy samples for n=185 stage IV patients with gastroesophageal (GEC, n=37), pancreatic (PC, n=70) and colorectal cancer (CRC, n=78) have been prospectively acquired pretherapeutically and every 2 weeks during chemotherapy until restaging, analyzed using ddPCR and correlated with response to treatment and actual volumetric tumor burden. Results Detection rates were 88.5% (CRC), 77.8% (GEC) and 64.3% (PC). Median pretherapeutic ctDNA MAF was 11.9% (CRC), 1.5% (GEC) and 1.6% (PC). ctDNA was significantly correlated with total tumor volume, especially with hepatic and lung lesion volume, but not with primary tumor volume in all tumor entities. Logistic regression revealed a decline of under 58% of the pretherapeutic MAF to predict response to treatment already after 2 weeks (CRC spec. 97.8%, sens. 92.3%, GEC spec. 100%, sens. 66.7%, PC spec. 100%, sens. 91.7%). This was accompanied with a significant impact on OS and PFS for all tumor entities. Discussion ctDNA represents an already clinical applicable biomarker with remarkable sensitivity and specificity in displaying actual tumor burden, prediction of prognosis and response to treatment. This biomarker is superior to current gold standard markers CEA, CA19-9 and CA72-4 and predicts response to systemic treatment >80% faster than computed tomography. Correlation of ctDNA with actual volumetric tumor burden and outcome in mCRC 1Gastrointestinal Cancer Center, Linz, Austria; 2Department of Surgery, Ordensklinikum Linz, Austria; 3Johannes Kepler University Linz, Medical Faculty, Linz, Austria; 4Department of Diagnostic and Interventional Radiology, Ordensklinikum Linz, Austria; 5Laboratory for Molecular Genetic Diagnostics, Ordensklinikum Linz, Austria; 6Institute of Human Genetics, Medical University of Innsbruck, Austria; 7Department of Internal Medicine I for Hematology with Stem Cell Transplantation, Hemostaseology and Medical Oncology, Ordensklinikum Linz, Austria; 8VYRAL, Linz, Austria Background ctDNA has emerged as a promising biomarker in colorectal cancer (mCRC) with strong association to prognosis that is currently evaluated for its clinical applicability in response prediction. However, little is known about its actual derivation and correlation to tumor volume and site. Methods Liquid biopsy samples (n=384) for n=78 stage IV mCRC patients have been acquired pretherapeutically and every 2 weeks during chemotherapy until restaging, analyzed using ddPCR (for mutational (e.g. KRAS) and methylation markers (WIF/NPY)) and correlated with response to treatment and actual volumetric tumor burden. Results Pretherapeutic ctDNA was detectable in 69 patients (88.5%) and median MAF was 11.9%. Mutational pattern was very heterogeneously with 28 different mutations (KRAS 66.7%, TP 17.9%, BRAF 11.5%, NRAS 2.6%). ctDNA correctly predicted response to treatment in 95.8% and 87.5% after only 2 weeks of treatment (CEA 74.5% and 5.5%, NPY/WIF 85.1% and 64.2%). ctDNA was associated with total tumor volume (R=0.568, p<0.000), especially with liver tumor volume (R=0.713, p<0.000). Similar results were found for methylation (R=0.543, p<0.000; R=0.733, p<0.000) and CEA (R=0.619, p<0.000; R=0.759, p<0.000). ctDNA dynamics after 2 weeks of treatment showed strong impact on OS (8.0 (95% CI 5.6-10.4) vs. 21.0 (95% CI 16.7-25.3) months) and PFS (2.0 (95% CI 1.3-2.7) vs. 11.0 (95% CI 9.0-13.0) months, p<0.000). Discussion ctDNA is correlated with actual volumetric tumor burden. ctDNA is superior to CEA and WIF/NPY in detecting response to treatment. ctDNA is the strongest biomarker for prognosis and predicts response to treatment after only 2 weeks of systemic treatment. Achieving clinical applicability for circulating tumor DNA (ctDNA) as biomarker for neoadjuvant chemotherapy vs. surgery in localized pancreatic cancer 1Gastrointestinal Cancer Center, Linz, Austria; 2Department of Surgery, Ordensklinikum Linz, Austria; 3Johannes Kepler University Linz, Medical Faculty, Linz, Austria; 4Department of Diagnostic and Interventional Radiology, Ordensklinikum Linz, Austria; 5Department of Internal Medicine I for Hematology with Stem Cell Transplantation, Hemostaseology and Medical Oncology, Ordensklinikum Linz, Austria; 6Laboratory for Molecular Genetic Diagnostics, Ordensklinikum Linz, Austria; 7Institute of Human Genetics, Medical University of Innsbruck, Austria; 8VYRAL, Linz, Austria Background ctDNA derives from distant metastases and advanced locoregional disease in pancreatic cancer (PDAC). Furthermore, ctDNA can be used to predict response to treatment after only 2 weeks of systemic treatment in mPDAC. Applicability for NACT evaluation in localized PDAC was hampered by low detection rates and thus necessity of broad-spectrum analysis and potential delay of treatment up to now. Methods Liquid biopsy samples of n=147 patients with locPDAC were collected preoperatively, one (n=66) and 10 days (n=30) after surgery. Samples were evaluated using ddPCR in a new testing regimen and results were correlated to volumetric findings and outcome. Results Pretherapeutic detection rates have improved from 10% to 36.1% (19.7% (1st day), 13.3% (10th day)). ctDNA did not correlate with primary tumor volume (R=0.071, p=0.605), but nodal positivity (p=0.029). Pretherapeutic ctDNA was associated with significantly worse OS (10.1 (95%CI 4-16.2) vs. 36 (95%CI 22.1-49.9) months) and DFS (6 (95%CI 2.6-9.4) vs. 23.5 (95%CI 17.9-29.1) months). Pretherapeutic CA19-9 was not associated with OS or DFS. Neither above 500 U/ml (p=0.285, p=0.162), nor >1000U/ml (p=0.419, p=0.495). Postoperative ctDNA detectability did not reach statistical significance but showed strong correlation to OS (low numbers, HR 3.120, p=0.083). Discussion Our new testing strategy significantly improves the pretherapeutic detection rate (3x) with constantly high prognostic impact. Turnaround time from sampling of liquid biopsy to results and thus clinical assessment for treatment decisions is only 3 days. Thus, these findings pave the way for ctDNA guided treatment decisions in locPDAC (NACT vs. upfront surgery) under study conditions. Endoskopische Gastroenterostomie mit Hilfe von LAMS – Entwicklung zur standardisierten Technik Ordensklinikum Linz GmbH, Österreich Einleitung/Background Die Durchführung einer endoskopischen Gastroenterostomie ist eine technisch äußerst anspruchsvolle Intervention, welche ein standardisiertes Vorgehen erfordert. Seit Etablierung eines Standards konnten die Zahlen der sicheren Durchführung gesteigert und die Interventionsdauer verkürzt werden. Die Durchführung einer LAMS Gastroenterostomie sollte nur von Untersuchern mit hoher Expertise in Endosonographie durchgeführt werden.
Cytoreductive surgery (CRS) and hyperthermal intraperitoneal chemotherapy (HIPEC) in peritoneal metastatic colorectal cancer: 10 years of CRS and HIPEC at the Ordensklinikum Linz 1Department of Surgery, Ordensklinikum Linz, Austria; 2Johannes Kepler University Linz, Medical Faculty, Linz, Austria; 3VYRAL, Linz, Austria; 4Department of Surgery, Paracelsus Medical University Salzburg, Salzburg, Austria Introduction: Hyperthermal intraperitoneal chemotherapy (HIPEC) in combination with cytoreductive surgery (CRS) has been increasingly used to treat peritoneal metastases in colorectal cancer. The aim of this study is to evaluate the clinical effectiveness as well as the complication and mortality rates of this therapy option. Methods: Patients with peritoneal metastatic colorectal cancer (small bowel (n=3; 3.5%), right colon (n=35; 41.2%), left colon (n=41; 48.2%) and appendix (n=6; 7.1%)) who underwent CRS/HIPEC at the Ordensklinikum Linz (OKL) between 2013 and 2022 (n=85/145) versus a matched comparison group (chemotherapy (CTX) alone for peritoneum only colorectal cancer (PERonly mCRC)) were analysed retrospectively from our prospective database. CRS/HIPEC was superior to CTX alone in both median PFS (58 months (95% CI 23.7-92.3), p=0.022) and OS ((mean 68. 6 (95% CI 58. 4-78. 7) vs. 26. 4 months (95% CI 15. 8-36. 9); p<0.000; (median not reached in CRS/HIPEC)). Conclusion: CRS/HIPEC shows a clear survival advantage in PERonly mCRC compared to chemotherapy alone. Therefore, the possibility of CRS/HIPEC therapy should be considered in these patients. In order to ensure a complete cytoreduction with low morbidity and mortality, this procedure should be performed in a high-volume centre. The Pulmonary Nodule and Breast Carcinoma - A Surgical Chameleon Klinik Oberwart Introduction/Background: Pulmonary round lesions are one of the most common comorbidities in both the initial presentation and the oncological follow-up of patients with breast cancer. However, recent years' experiences underscore that the straightforward assumption of a lung metastasis is not always accurate. Methods: Based on three cases, various methods for diagnosing and treating pulmonary round lesions were investigated. Diagnostic procedures such as CT-guided biopsies, tumor marker monitoring, and positron emission tomography were employed to identify and characterize these tumors. Results: Through the meticulous investigation using the aforementioned methods, different diagnoses were established, leading to significant therapeutic consequences. Summary/Conclusion: Histological confirmation of a pulmonary round lesion and subsequent surgical resection should be considered standard procedures. These case studies illustrate the spectrum of possible diagnoses and the resulting diverse therapeutic approaches. |

Metachronic lung metastasis following operated PDAC of the pancreatic head. Is surgery still offering a therapeutic possibility ? Chronology of a success through an aggressive surgical treatment sequence. 1Klinik Oberwart, Abteilung für Allgemein-, Thorax-, Viszeral- und Gefäßchirurgie Österreich; 2Privatklinik Villach, Österreich Einleitung/Background Although therapeutic recommendations for the surgical treatment of synchronously occurring liver metastases in the treatment of PDAC are existing, a metachronous metastasis after resection of the primum continues to pose major challenges for the treating physicians. Even if large-scale case-series and randomized trials on this topic are missing, small case series and case reports already show a benefit for resections of metachronous isolated lung metastases. On the basis of a case study, we are presenting an (aggressive) surgical therapy approach which led to a significant OAS increase. Material and methods: We are presenting the case of a 79-year-old female patient with newly emerged pulmonary nodules in both lungs 42 months after initial surgical treatment of neoadjuvant treated PDAC. The nodules were surgically removed (with histological confirmation of the PDAC metastasis). After another 12 months, the patient showed new nodules in the right lung which were treated with microwave ablation. 27 months after this treatment, we detected another three foci in the left lung which were surgically removed. (with the histological confirmation of PDAC metastases). Result: After this last treatment the patient is now free of signs of disease Conclusion: Despite the lack of corresponding literature recommendations, the clinical oncological course, in this case, is justifying the repeated surgical procedures. This case underlines that there must be an opinionated and willful surgical representative in the tumor board. Molecular patterns, laboratory values and clinical parameters which help to identify patients who are more likely to benefit from such therapies are desirable. Is the K-ras mutation status a prognostical tool to predict metastasis formation for CRC patients?? 1Klinik Oberwart, Abteilung für Allgemein-, Thorax-, Viszeral- und Gefäßchirurgie, Österreich; 2Klinikum Augsburg, Abteilung für Onkologie Introduction CRC is the third most common tumor entity in the Western world. New CRC cases will increase from 1.9 million to 3.2 million untill 2040. Although environmental factors are an increasing risk factor today, genetic aberrations play a key role in CRC development and tumorigenesis. In particular, the K-ras oncogene seems to be of immense importance as a "gatekeeper" of the adenoma-carcinoma sequence. Whether the mutation status per se has a prognostic power for overall survival or leeds to a higher probability of metastatic formations remains unclear. Methods The aim of our study was to find out whether the K-ras mutation status itself influences the probability for metastatic formations or not. We performed a retrospective workup of over 600 patients treated in three centers. Primarily, the distributions were represented by means of descriptive statistics. Statistical analyses were then used to show a difference in cancer-specific survival and metastasis formation for patients with or without K-ras mutation. Results The hypothesis that K-RAS status affects the cancer-specific survival was evaluated and rejected using Kaplan-Meier curves and log rank tests. Neither the univariate nor the multivariate analysis showed a significant difference. The K-ras mutation status showed a slightly higher metastasis rate in the case of right-sided tumors. Conclusion With our study results, the prognostic significance of K-ras mutation status for the distribution of metastasis can be refuted. Only for the subgroup of right-sided carcinomas with a K-ras point mutation on codon thirteen, there seems to be a slightly higher probability of metastasis. Immunological impact of Axl/TGF-beta signaling in hepatocellular carcinoma 1Center for Cancer Research, Comprehensive Cancer Center, Medical University of Vienna, Vienna, Austria; 2Department of Surgery, Division of Hepatobiliary and Pancreatic Surgery, Mayo Clinic, Rochester, MN, USA; 3Department of Surgery, HPB Center, Viennese Health Network, Clinic Favoriten and Sigmund Freud Private University, Vienna, Austria; 4Max Perutz Labs, Department of Chromosome Biology, Center for Integrative Bioinformatics Vienna, University of Vienna, Vienna, Austria Einleitung/Background Methoden/Methods Ergebnisse/Results Zusammenfassung/Conclusion Minimally Invasive Esophagectomy - Clinical Implementation of a new Technique Universitätsklinik für Visceral-, Transplantations- und Thoraxchirurgie, Medizinische Universität Innsbruck Background: Methods: Results: Conclusions: A rare case of rectum wall metastasis in pancreatic cancer - a case report LK Korneuburg, Österreich Einleitung/Background Up to 40% of patients at the initial diagnosis of pancreatic cancer are without secondary blastomas. These occur more often in the liver and peritoneum, rarely in the adrenal glands and bones. There are only 10 case reports in the English literature describing metastasis to the colo-rectum. Methoden/Methods An 82-year-old patient presented to the emergency room with abdominal pain, nausea, vomiting and stool retention. The CT scan showed the picture of a mechanical colon ileus. The patient had been treated oncologically for UICC stage IV pancreatic adenocarcinoma of the pancreatic tail. Metastases in the liver segment VII and in the rectum had been radiologically and histologically confirmed, whereas a metastasis in the stomach had been described only radiologically. Since the initial diganosis the patient had received palliative chemotherapy which stabilized the disease for 19 months. A laparotomy with deep anterior rectum resection and creation of a stoma of the descending colon was performed. Histological workup confirmed the metastasis. The postoperative course was uneventful, palliative chemotherapy was continued and the patient lived another 8 months. Ergebnisse/Results Colo-rectal metastasis from pancreatic carcinoma has rarely been described. The most commopn location of secondary blastomas were the sigmoid colon and the transverse colon. The mean survival rate was 7 months after the initial diagnosis, our patient survived for 27 months. Zusammenfassung/Conclusion This is the 11th case of colon metastasis from pancreatic cancer in the English literature. It is important to consider metastasis if a colonic mass occurs in the presence of pancreatic cancer. |
