Introduction: Surgery is the only potentially curative treatment for colorectal cancer liver metastases (CRLM) and its indication and results have varied in the last 30 years., Methods: All patients operated on for CRLM in our centre from 1990 to 2021 were prospectively collected, establishing 3 subgroups based on the year of the first surgery: group A 1990-1999, group B 2000-2010, group C 2011-2021. Clinical characteristics and the results of survival, recurrence and prognostic factors were compared., Results: 1736 hepatectomies were included (Group A n = 208; Group B n = 770; Group C n = 758). Patients in group C had better survival at 5 and 10 years (A 40.5%/28.2%; B 45.9%/32.2%; C 51.6%/33.1%, p = 0.013), although there were no differences between groups in overall recurrence at 5 and 10 years (A 73%/75.7%; B 67.6%/69.2%, and C 63.9%/66%, p = 0.524), nor in liver recurrence (A 46.4%/48.2%; B 45.8%/48.2%; and C 44.4%/48.4%, p = 0.899). An improvement was observed in median survival after recurrence, being 19 months, 23 months, and 31 months (groups A, B and C respectively). Prognostic factors of long-term survival changed over the 3 study periods. The only ones that remained relevant in the last decade were the presence of >4 liver metastasis, extrahepatic disease at the time of hepatectomy, and intraoperative blood transfusion., Conclusions: Survival after surgery for CRLM has improved significantly, although this cannot be explained by a reduction in overall and hepatic recurrence, but rather by an improvement in post-recurrence survival. Involvement of the resection margin has lost prognostic value in the last decade., (Copyright © 2024 AEC. Published by Elsevier España, S.L.U. All rights reserved.)

Introduction: To decide treatment of hepatic cysts diagnosis between simple hepatic cyst (SHC) and cystic mucinous neoplasm (CMN). Radiological features are not patognomonic. Some studies have suggested the utility of intracystic tumor markers., Methods: Retrospective analysis of our prospective database including patients treated due to symptomatic SHC from 2003 to 2021. The aim of the study was to evaluate the results of treatment of symptomatic SHC and the usefulness of the determination of intracystic "carcinoembryonic antigen" (CEA) and "carbohydrate antigen" CA 19.9., Results: 50 patients diagnosed and treated for symptomatic SHC were included. In 15 patients the first treatment was percutaneous drainage. In 35 patients the first treatment was laparoscopic fenestration. Four patients were diagnosed of premalignant or malignant liver cystic lesions (MCN, IPMN, lymphoma B); three of them required surgery after initial fenestration and pathological diagnosis. Median CEA and CA 19-9 were 196 μg/L and 227.321 U/mL respectively. Patients with malignant or premalignant pathology did not have higher levels of intracystic tumor markers. Positive predictive value was 0% for both markers, and negative predictive value was 89% and 91% respectively., Conclusion: Values of intracystic tumor markers CEA and CA 19-9 do not allow distinguishing simple cysts from cystic liver neoplasms. The most effective treatment for symptomatic simple liver cysts is surgical fenestration. The pathological analysis of the wall of the cysts enables the correct diagnosis, allowing to indicate a surgical reintervention in cases of hepatic cyst neoplasia., (Copyright © 2023.

Introduction: A borderline resectable group (APBR) has recently been defined in adenocarcinoma of the pancreas. The objective of the study is to evaluate the results in the surgical treatment after neoadjuvancy of the APBR., Method: Between 2010 and 2014, we included patients with APBR in a neoadjuvant and surgery protocol, staged by multidetector computed tomography (MDCT). Treatment with chemotherapy was based on gemcitabine and oxaliplatin. Subsequently, MDCT was performed to rule out progression, and 5-FU infusion and concomitant radiotherapy were given. MDCT and resection were performed in absence of progression. A descriptive statistical study was performed, dividing the series into: surgery group (GR group) and progression group (PROG group)., Results: We indicated neoadjuvant treatment to 22 patients, 11 of them were operated, 9 pancreatoduodenectomies, and 2 distal pancreatectomies. Of the 11 patients, 7 required some type of vascular resection; 5 venous resections, one arterial and one both. No postoperative mortality was recorded, 7 (63%) had any complications, and 4 were reoperated. The median postoperative stay was 17 (7-75) days. The pathological study showed complete response (ypT0) in 27%, and free microscopic margins (R0) in 63%. At study clossure, all patients had died, with a median actuarial survival of 13 months (9,6-16,3). The median actuarial survival of the GR group was higher than the PROG group (25 vs. 9 months; p < 0.0001)., Conclusion: The neoadjuvant treatment of APBR allows us to select a group of patients in whom resection achieves a longer survival to the group in which progression is observed. Post-adjuvant pancreatic resection requires vascular resection in most cases., (Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.)

Objective: To analyse the indications and results of pancreatic metastasis resection in a university hospital., Patients and Methods: An analysis was performed on a prospective database from 1990 to 2010. The clinical-pathological and perioperative details, as well the follow-up results were analysed., Results: Of the 710 pancreatic resections performed, 7 cases (0.99%) were due to a metastasis in the pancreas. The mean age of the patients was 53.3 years (20-77 years), and 5 were male and 2 were women. Five (70%) patients were asymptomatic. The origin of the metastasis was: colon (n=3), kidney (n=2), jejunum (n=1), and testicle (n=1). In 4 cases they were situated in the head, 2 in the tail, and one in the body. The metastases were metachronous in 4 (57%) patients and the disease free interval was 29 months (17-48). There were 3 cases (43%) of synchronous metastases, with a mean recurrence-free time of 14 months, and survival of 21.6 months. This was lower than that of patients with metachronous metastases, which was 27.8 months and with a survival of 32 months, respectively. The overall disease free interval and survival was 21.85 months and 27.5 months, respectively., Conclusion: Resection of pancreatic metastases can extend survival in selected patients., (Copyright © 2012 AEC.
