Feasibility and short-term outcomes in liver-first approach: a Spanish snapshot study (the RENACI project)

Producción CientíficaSimple Summary: Current evidence does not provide enough information for selecting a tailored approach pathway in patients with colorectal cancer and synchronous liver metastases. There are no randomized clinical trials or prospective series comparing the classical approach with the liver-first approach. In addition, information on the proportion of patients who actually complete the therapeutic regimen is limited. The RENACI Project was a prospective National Registry performed on patients with colorectal cancer and synchronous liver metastases undergoing the liver-first approach. This study aimed to present the data of feasibility and short-term outcomes of the Spanish National Registry of Liver First Approach (the RENACI Project).(1) Background: The liver-first approach may be indicated for colorectal cancer patients with synchronous liver metastases to whom preoperative chemotherapy opens a potential window in which liver resection may be undertaken. This study aims to present the data of feasibility and short-term outcomes in the liver-first approach. (2) Methods: A prospective observational study was performed in Spanish hospitals that had a medium/high-volume of HPB surgeries from 1 June 2019 to 31 August 2020. (3) Results: In total, 40 hospitals participated, including a total of 2288 hepatectomies, 1350 for colorectal liver metastases, 150 of them (11.1%) using the liver-first approach, 63 (42.0%) in hospitals performing <50 hepatectomies/year. The proportion of patients as ASA III was significantly higher in centers performing ≥50 hepatectomies/year (difference: 18.9%; p = 0.0213). In 81.1% of the cases, the primary tumor was in the rectum or sigmoid colon. In total, 40% of the patients underwent major hepatectomies. The surgical approach was open surgery in 87 (58.0%) patients. Resection margins were R0 in 78.5% of the patients. In total, 40 (26.7%) patients had complications after the liver resection and 36 (27.3%) had complications after the primary resection. One-hundred and thirty-two (89.3%) patients completed the therapeutic regime. (4) Conclusions: There were no differences in the surgical outcomes between the centers performing <50 and ≥50 hepatectomies/year. Further analysis evaluating factors associated with clinical outcomes and determining the best candidates for this approach will be subsequently conducted.Asociación Española de Cirujanos - (grant Research Projects 2020

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID)

Background: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients. Methods: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020. Variables related to the primary tumor, demographics, clinical characteristics of metastasis, location in the pancreas, type of pancreatic resection performed and data on short and long-term evolution after pancreatic resection were collected. Results: The study included 116 patients. The mean time between nephrectomy and pancreatic metastases' resection was 87.35 months (ICR: 1.51-332.55). Distal pancreatectomy was the most performed technique employed (50 %). Postoperative morbidity was observed in 60.9 % of cases (Clavien-Dindo greater than IIIa in 14 %). The median follow-up time was 43 months (13-78). Overall survival (OS) rates at 1, 3, and 5 years were 96 %, 88 %, and 83 %, respectively. The disease-free survival (DFS) rate at 1, 3, and 5 years was 73 %, 49 %, and 35 %, respectively. Significant prognostic factors of relapse were a disease free interval of less than 10 years (2.05 [1.13-3.72], p 0.02) and a history of previous extrapancreatic metastasis (2.44 [1.22-4.86], p 0.01). Conclusions: Pancreatic resection if metastatic RCC is found in the pancreas is warranted to achieve higher overall survival and disease-free survival, even if extrapancreatic metastases were previously removed. The existence of intrapancreatic multifocal compromise does not always warrant the performance of a total pancreatectomy in order to improve survival. (C) 2021 The Authors. Published by Elsevier Ltd

Repeated pancreatic resection for pancreatic metastases from renal cell Carcinoma: A Spanish multicenter study (PANMEKID)

Background and objectives: Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease -free survival. Methods: Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. Results: The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). Conclusion: Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection

Encuesta nacional sobre las unidades de virugía pancreática

Spanish Pancreatic Surgery Group (AEC CE-IHPBA).[EN]: [Introduction] The technical, human, scientific and treatment characteristics of the Units that manage complex pathologies have not been studied in depth. [Methods] Multi-institutional descriptive study (survey) developed jointly by the Hepatobiliary-Pancreatic Division of the Spanish Association of Surgeons and the Spanish Chapter of the IHPBA (International Hepatopancreatobiliary Association) on the characteristics of the Units where pancreatic surgery is performed in Spain. [Results] 82 surveys were sent. 69 medical centers responded (84%), belonging to 16 autonomous regions of Spain. The total population of these regions was 23183262 (50% of the Spanish population). The average number of beds per hospital was 673. The unit that performs pancreatic surgery is a Hepatobiliary-Pancreatic Surgery Unit or HPB and Liver Transplant Surgery Unit in 56 hospitals (77%). The average number of surgeons is 4.5 per Unit. Fifty-five Units (80%) lack specific anesthetists. The number of pancreatectomies performed during 2017 at the hospitals surveyed was 1315 pancreaticoduodenectomies (PD), 566 distal pancreatectomies (DP) and 178 total pancreaticoduodenectomies (TPD). The mean per hospital was 19.1 PD, 8.2 DP and 2.6 TPD. PD was usually performed using a classic approach, with pancreatojejunostomy, single-loop technique, antecolic gastrojejunostomy and using two drain tubes. Only 7 units performed PD laparoscopically and only 13 units did not perform laparoscopic DP. [Conclusions] This survey provides updated information about the majority of the Units where pancreatic surgery is performed in Spain and could also serve as a starting point for prospective multicenter studies.[ES]: [Introducción] Las características técnicas, humanas, científicas y asistenciales de las Unidades que atienden una patología compleja son poco estudiadas y conocidas. [Métodos] Estudio descriptivo multiinstitucional (encuesta) desarrollado conjuntamente por la sección Hepatobiliopancreática de la Asociación Española de Cirujanos y el capítulo español de la IHPBA (Asociación Internacional Hepatopancreatobiliar) sobre las características de las Unidades donde se realiza cirugía pancreática en España. [Resultados]Se enviaron 82 encuestas. Respondieron 69 centros (84%) pertenecientes a 16 comunidades autónomas. La suma de habitantes de las áreas propias fue 23.183.262. El número medio de camas por hospital fue 673. La Unidad que realiza la cirugía pancreática es la Unidad de Cirugía Hepatobiliopancreática o Cirugía HPB y Trasplante Hepático en 56 hospitales (77%). El número medio de cirujanos es 4,5 por Unidad. Cincuenta y cinco Unidades (80%) carecen de anestesistas específicos. El número de pancreatectomías realizadas durante 2017 en los centros encuestados fue 1.315 duodenopancreatectomías cefálicas (DPC), 566 pancreatectomías distales (PD) y 178 duodenopancreatectomías totales (DPT). La media por centro fueron 19,1 DPC, 8,2 PD y 2,6 DPT. La DPC más habitual se realiza mediante abordaje clásico, con pancreatoyeyunostomía, montaje en un asa, con gastroyeyunostomía antecólica y 2 drenajes. Solo 7 Unidades efectúan la DPC por laparoscopia y solamente 13 Unidades no realizan PD laparoscópica. [Conclusiones]Esta encuesta proporciona información actualizada del trabajo asistencial y científico de un gran porcentaje de las Unidades donde se realiza cirugía pancreática en España, y además puede servir de punto de partida a trabajos multicéntricos prospectivos

Duodenal Adenocarcinoma: The Relationship between Type of Surgery and Site of Recurrence in a Spanish Cohort

We present a multicenter retrospective study of patients undergoing surgery for duodenal adenocarcinoma, from January 2010 to August 2020, in order to determine the epidemiological characteristics and the oncological results after surgical resection obtained in this rare tumor. Variables: demographics; tumor location; surgical intervention and immediate postoperative period; and post-surgical follow-up information, such as recurrence, overall survival (OS), and disease-free survival (DFS). A total of 32 patients underwent surgery. The median age was 69.74 years (IQR 60.47–79.09) and the male/female distribution was 3:1. The surgeries performed were: pancreaticoduodenectomy (PD) in 16 (50%) patients, segmental resection in 13 (40.6%), and the local excision of the lesion in three (9.4%). The R0 rate was higher in PD (86.7% vs. 42.9%; p = 0.013). The OS and DFS rate at one, three and five years was 95%, 70%, and 60% and 86%, 55%, and 48%, respectively. There was a greater trend towards recurrence in patients who did not undergo PD (53.8% vs. 25%; p = 0.14) and conservative surgery seemed to be associated with more local recurrence than PD (57.1% vs. 33.3%; p = 0.49). PD and limited resection are both valid options in the cases of non-ampullary duodenal adenocarcinoma, although PD presented lower rates of loco-regional recurrence

We present a national multicentric study on TP and a comparison with the existing literature. [Methods] A prospective observational study using data from the national registry of patients after pancreaticoduodenectomy and TP performed for any indication during the study period: January 1–December 31, 2015. [Results] 1016 patients were included from 73 hospitals, 112 of whom had undergone TP. The percentage of TP from the total number of cases was 11%. The mean age was 63.5 years, and 57.2% were males. The most frequently suspected radiological diagnosis was pancreatic cancer (58/112 cases). The most common TP technique was “mesentery artery first” (43/112 cases). Venous resections were performed in 23 patients (20.5%). The percentage of postoperative complications within 90 days was 50%, but major complications (>IIIA) were only 20.7%. The overall 90-day mortality was 8% (9 patients). The average stay was 20.7 days. The 3 most frequent definitive histological diagnoses were: adenocarcinoma of the pancreas, intraductal papillary mucinous neoplasm and chronic pancreatitis. The R0 rate was 67.8%. [Conclusions] This study shows that the morbidity and mortality results of TP in Spain are similar or superior to previous publications. More precise TP studies are necessary, focused on specific complications such as endocrine insufficiency.[ES]: [Introducción] La pancreatectomía total (PT) es una intervención infrecuente, con unas indicaciones no claramente definidas y unos resultados postoperatorios no estandarizados.
