Mini-mesohepatectomy for tumours at the hepatocaval confluence: A cases series and review of the literature
Liver lesions located adjacent to the middle hepatic vein (MHV) at the hepatocaval confluence are rare. Mini-mesohepatectomy (MMH) allows resection of these lesions with preservation of liver parenchymal volume thus reducing the risk of post-hepatectomy liver failure (PHLF). We evaluated our experience of MMH at our institution and assessed post-operative complications, disease free survival (DFS) and overall survival (OS). All patients undergoing MMH at our institution were included in the study. Intra-operative parameters, histopathological data, DFS and OS were evaluated. 11 patients with colorectal liver metastasis underwent MMH between Jan 2012 and Dec 2020. MMH resulted in R0 resection rate in all patients with no PHLF. There were 1 post-operative bile leaks but no mortality following MMH. Median DFS was 13.5 months with OS being 60 months. MMH offers safe oncological resection of lesions at the MHV at the hepatocaval confluence and should be considered in patients presenting with such lesions
Complete Primary Pathological Response Following Neoadjuvant Treatment and Radical Resection for Pancreatic Ductal Adenocarcinoma.
INTRODUCTION: Neoadjuvant treatment (NAT) for borderline (BD) or locally advanced (LA) primary pancreatic cancer (PDAC) is now a widely adopted approach. We present a case series of patients who have achieved a complete pathological response of the primary tumour on final histology following neoadjuvant chemotherapy +/- chemoradiation and radical surgery. METHODS: Patients who underwent radical pancreatic resection following neoadjuvant treatment between March 2006 and March 2023 at a single institution were identified by retrospective case note review of a prospectively maintained database. RESULTS: Ten patients were identified to have a complete primary pathological response (ypT0) on postoperative histology. Before treatment, five patients were considered BD and five were LA according to National Comprehensive Cancer Network guidelines. All patients underwent staging Computed Tomography (CT) and nine underwent 18Fluorodeoxyglucose Positron Emission Tomography (18FDG-PET/CT) imaging, with a mean maximum standardized uptake value (SUVmax) of the primary lesion at 6.14 ± 1.98 units. All patients received neoadjuvant chemotherapy, and eight received further chemoradiotherapy prior to resection. Mean pre- and post-neoadjuvant treatment serum Ca19-9 was 148.0 ± 146.3 IU/L and 18.0 ± 18.7 IU/L, respectively (p = 0.01). The mean duration of NAT was 5.6 ± 1.7 months. The mean time from completion of NAT to surgery was 13.1 ± 8.3 weeks. The mean lymph node yield was 21.1 ± 10.4 nodes, with one patient found to have 1 lymph node involved. All resections were reported to be R0. The mean length of stay was 11.8 ± 6.2 days. At the time of analysis, one death was reported at 35 months postoperatively. Two cases of recurrence were reported at 16 months (surgical bed) and 33 months (pulmonary). All other patients remain alive and under active surveillance. The current overall survival is 26.6 ± 20.7 months and counting. CONCLUSIONS: Complete primary pathological response is uncommon but possible following neoadjuvant treatment in patients with PDAC. Further work to identify the common denominator within this unique cohort may lead to advances in the therapeutic approach and offer hope for patients diagnosed with borderline or locally advanced pancreatic ductal adenocarcinoma
Surgical Outcomes Following Neoadjuvant Treatment for Locally Advanced and Borderline Resectable Pancreatic Ductal Adenocarcinoma.
OBJECTIVE: To assess overall survival (OS), compare the effects of neoadjuvant treatment, and describe surgical outcomes for patients undergoing pancreatic resection following chemotherapy and/or chemoradiotherapy (CRT) for borderline resectable (BR) or locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: We approach BR/LA PDAC using chemotherapy followed by selective CRT to the primary site of disease where either the surgical margin remains radiologically threatened following chemotherapy or as a further downstaging treatment. METHODS: Retrospective study of patients between December 2005 and June 2023 at the Royal Marsden Hospital, London, United Kingdom. RESULTS: A total of 54 patients were included. The OS between R1 and R0 patients was significantly different: 7.5 versus 23 versus 42 versus 51 months for R1 chemo, R1 chemo and CRT, R0 chemo and R0 chemo, and CRT groups, respectively, P < 0.001. Similarly, 9 versus 18 versus 42 versus 41 months for N1 chemo, N1 chemo and CRT, N0 chemo and N0 chemo, and CRT groups, respectively, P = 0.0026. Multivariable Cox regression model demonstrated that perineural invasion (hazard ratio: 2.88, 95% confidence interval: 1.06-7.81; P = 0.038) and perivascular invasion (PVI) (HR: 2.76, 95% CI: 1.24-6.13; P = 0.013) were associated with significantly worse OS. Chemo and CRT conferred OS benefit compared to chemo only (7 vs 23 months, P = 0.004) in PVI-positive patients. CONCLUSIONS: Neoadjuvant chemotherapy followed by CRT compared to chemotherapy alone for resected BD and LA PDAC was demonstrated to significantly improve median OS, in particular, in patients with R1 resection margins, ypN1 nodal status, and perivascular invasion
Radical resection of large metastatic non-functioning pancreatic neuroendocrine carcinoma complicated by splenic vein thrombosis and sinistral portal hypertension.
INTRODUCTION AND IMPORTANCE: There are limited reports in the literature of radical surgical resection for pancreatic neuroendocrine carcinoma (PNEC). In patients with non-functioning PNEC (NF-PNEC) within the tail of the pancreas tumours can cause splenic vein thrombosis (SVT) and subsequent sinitral portal hypertension (SPH). Radical surgical resection in such patients with concomitant liver metastasis has not previously been reported. CASE PRESENTATION: We present a 67-year old female patient who presented with a large NF-PNEC within the tail of the pancreas with liver metastasis. We performed a distal pancreatectomy, splenectomy, partial gastrectomy and liver resection to achieve radical resecton. DISCUSSION: All patients with NF-PNEC within the tail of the pancreatic should be considered for radical surgical resection. In the presence of multi-visceral involvement and complications such as SVT and/or SPH multi-speciality surgical expertise is likely to be required. CONCLUSION: Radical multi-visceral resection for large NF-PNEC can be safely performed in the presence of SVT and SPH
The Diagnostic Accuracy of (18) F-FGD-PET/CT for Cancer of the Gallbladder: A Retrospective Study
Background Gallbladder cancer has a poor prognosis and imaging can have variable diagnostic accuracy. We assessed the ability of preoperative (18) F-fluorodeoxyglucose positron emission tomography computed tomography ( (18) F-FDG-PET/CT) imaging to predict a postoperative histological diagnosis of gallbladder cancer. Method A retrospective analysis was undertaken in a cohort of patients, who had suspected gallbladder cancer on cross-sectional imaging and that underwent preoperative FDG-PET/CT scan. The discriminatory power of FDG-PET/CT was determined in receiver operator characteristic (ROC) analysis and diagnostic accuracy parameters were estimated at different thresholds of maximum standard unit value (SUV (max) ) (.) Results Twenty-two patients were included in the study; 7 had malignant and 15 benign diagnoses. There was no statistically significant difference between the measured SUV (max) between the two groups ( p = 0.71). With an area under the curve of 0.486, the ROC curve did not indicate any discriminatory power of FDG-PET/CT at any potential threshold of SUV (max.) Conclusion This study indicates that the diagnosis of primary gallbladder cancer cannot be accurately confirmed with FDG PET/CT scanning
The Cancer Hub Approach for Upper Gastrointestinal Surgery During COVID-19 Pandemic: Outcomes from a UK Cancer Centre
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic caused unprecedented disruption to global healthcare delivery. In England, the majority of elective surgery was postponed or cancelled to increase intensive care capacity. Our unit instituted the ‘RM Partners Cancer Hub’ at the Royal Marsden Hospital in London, to deliver ongoing cancer surgery in a ‘COVID-lite’ setting. This article describes the operational set-up and outcomes for upper gastrointestinal (UGI) cancer resections performed during this period. METHODS: From April 2020 to April 2021, the Royal Marsden Hospital formed the RM Partners Cancer Hub. This approach was designed to coordinate resources and provide as much oncological treatment as feasible for patients across the RM Partners West London Cancer Alliance. A UGI surgical case prioritisation strategy, along with strict infection control pathways and pre-operative screening protocols, was adopted. RESULTS: A total of 231 patients underwent surgery for confirmed or suspected UGI cancer during the RM Partners Cancer Hub, with 213 completed resections and combined 90-day mortality rate of 3.5%. Good short-term survival outcomes were demonstrated with 2-year disease free survival (DFS) and overall survival (OS) for oesophageal (70.8% and 72.9%), gastric (66.7% and 83.3%) and pancreatic cancer resections (68.0% and 88.0%). One patient who developed perioperative COVID-19 during the RM Partners Cancer Hub operation made a full recovery with no lasting clinical sequelae. CONCLUSION: Our experience demonstrates that the RM Partners Cancer Hub approach is a safe strategy for continuing upper gastrointestinal (GI) resectional surgery during future periods of healthcare service disruptio
Enhancement of colorectal cancer liver metastases with gadoxetate-enhanced MRI at multiple time points is associated with disease-free survival following hepatectomy.
OBJECTIVES: To investigate signal intensity of colorectal cancer liver metastases (CRLM) at hepatobiliary phase (HBP) gadoxetate-enhanced MRI at 2 time points pre- (TP1) and post- chemotherapy (TP2) and association with disease-free survival (DFS) in patients undergoing curative liver resection. METHODS: Retrospective study was conducted. Single largest tumours were outlined and HBP T1 signal intensity was measured and normalized to skeletal muscle at TP1 and TP2. Enhancement thresholds were defined and risk groups at each TP and Kaplan-Meier survival curves were compared using the log-rank test. Univariate and multivariate association of enhancement and 8 clinical features with risk of recurrence were calculated using Cox proportional hazards. RESULTS: 82 patients (48 male, mean age 59 years) underwent 135 imaging studies, 58 at TP1, 77 at TP2, and 53 patients at TP1 + 2. Of 82 patients, 58 recurred with a median time to recurrence of 11.7 months. Enhancement of ≥135 and ≥15 at TP1 and TP2, respectively, were predictive of reduced risk of recurrence (P .05). Change in enhancement between TP was not associated with risk of recurrence; however, tumours that consistently exhibited low enhancement were 9 times more likely to recur. CONCLUSIONS: Increased CRLM enhancement in the HBP following gadoxetic acid at 2 TPs is associated with improved DFS in patients undergoing liver resection. This initial observation warrants further investigation of serial enhancement measurements as prognostic biomarkers. ADVANCES IN KNOWLEDGE: Dual-time point signal assessment may be informative for clinical outcomes in CRLM undergoing resection
Effect of perioperative FLOT versus ECF/ECX on short-term outcomes after surgery for resectable oesophagogastric adenocarcinoma: propensity score-matched study.
BACKGROUND: Perioperative FLOT (fluorouracil plus leucovorin, oxaliplatin, and docetaxel) chemotherapy is a recent regimen used to treat resectable oesophagogastric (OG) adenocarcinoma, associated with improved overall survival versus earlier chemotherapy strategies. This study compared short-term perioperative morbidity in a large tertiary centre series of FLOT to a matched cohort receiving ECX/ECF (epirubicin, cisplatin, capecitabine (X) or 5-fluorouracil (F)). METHODS: Consecutive patients completing four perioperative cycles of FLOT and proceeding to surgery with resectable OG adenocarcinoma were included. This was matched to patients from a historic ECX/ECF cohort from the same institution. A propensity score was calculated, and a secondary analysis using a propensity-matched group performed. RESULTS: Cohorts were matched by tumour location and operations performed. In total there were 129 (64.5 per cent) oesophageal and 71 (35.5 per cent) gastric resections (FLOT 57 oesophageal, 43 gastric; ECF/ECX 64 oesophageal, 36 gastric). The median length of stay after surgery was 12 days in the FLOT group versus 15 in ECF/ECX (P = 0.035). There were no significant differences in overall perioperative complications and, specifically, no difference in OG anastomotic leaks, analysed by site (gastric (FLOT 0/79 (0 per cent) versus ECX 2/79 (2.5 per cent); P = 0.123), oesophageal (FLOT 4/121 (3.3 per cent) versus ECX 5/121 (4.1 per cent); P = 0.868) or type of surgery (open FLOT 1/121 (0.8 per cent) versus ECX 3/121 (2.5 per cent); P = 0.368; minimally invasive (FLOT 3/121 (2.5 per cent) versus ECX 2/121 (1.7 per cent); P = 0.555)). There was no statistical difference in leak-related return to theatre, 30-day (FLOT 0 (0 per cent) versus ECX 3/100 (3.0 per cent); P = 0.081), or 90-day (FLOT 0 (0 per cent) versus ECX 2/100 (2.0 per cent); P = 0.155) mortality. CONCLUSION: In terms of surgical complications, FLOT and ECX/ECF were equally safe in patients undergoing resection for OG adenocarcinoma
Is percutaneous cholecystostomy a good alternative treatment for acute cholecystitis in high-risk patients?
Cholecystectomy is the treatment of choice for acute cholecystitis but the management of high-risk surgical patients is a difficult dilemma. Percutaneous cholecystostomy (PC) could represent a safer and less invasive option. The aim of the study was to assess the outcomes of PC in high-risk patients. This is a retrospective single-center study; data were collected from our hospital electronic record system. From February 2009 to March 2014, there were 753 patients admitted with acute cholecystitis. Of these 39 were considered high risk for surgery and underwent PC during their hospital stay. The radiological approach was transperitoneal in 29 patients and transhepatic in 10 patients. Median follow-up was 19 months. There were 27 males (69.2%) and 12 females (30.8%) with a mean age of 72 years (range 41-90 years). Twenty-seven patients had PC as definitive treatment (group A) and 12 patients as a bridge to cholecystectomy (group B). There were no postprocedure complications. Five patients in group A were readmitted once with another episode of cholecystitis after PC (18.5%), one patient in group B was readmitted with cholecystitis after two years before proceeding to cholecystectomy, and two patients were readmitted after cholecystectomy (16.6%) for intra-abdominal collections treated with percutaneous radiological drainage. Seven patients died (17.9%) as a result of severe biliary sepsis during their index hospital admission. PC is a safe approach in high-risk patients with acute cholecystitis and can provide satisfactory long-term results when cholecystectomy is not a viable option.</p
Adjuvant chemotherapy for adenocarcinoma arising from intraductal papillary mucinous neoplasia: multicentre ADENO-IPMN study
Background: The clinical impact of adjuvant chemotherapy after resection for adenocarcinoma arising from intraductal papillary mucinous neoplasia is unclear. The aim of this study was to identify factors related to receipt of adjuvant chemotherapy and its impact on recurrence and survival. Methods: This was a multicentre retrospective study of patients undergoing pancreatic resection for adenocarcinoma arising from intraductal papillary mucinous neoplasia between January 2010 and December 2020 at 18 centres. Recurrence and survival outcomes for patients who did and did not receive adjuvant chemotherapy were compared using propensity score matching. Results: Of 459 patients who underwent pancreatic resection, 275 (59.9%) received adjuvant chemotherapy (gemcitabine 51.3%, gemcitabine–capecitabine 21.8%, FOLFIRINOX 8.0%, other 18.9%). Median follow-up was 78 months. The overall recurrence rate was 45.5% and the median time to recurrence was 33 months. In univariable analysis in the matched cohort, adjuvant chemotherapy was not associated with reduced overall (P = 0.713), locoregional (P = 0.283) or systemic (P = 0.592) recurrence, disease-free survival (P = 0.284) or overall survival (P = 0.455). Adjuvant chemotherapy was not associated with reduced site-specific recurrence. In multivariable analysis, there was no association between adjuvant chemotherapy and overall recurrence (HR 0.89, 95% c.i. 0.57 to 1.40), disease-free survival (HR 0.86, 0.59 to 1.30) or overall survival (HR 0.77, 0.50 to 1.20). Adjuvant chemotherapy was not associated with reduced recurrence in any high-risk subgroup (for example, lymph node-positive, higher AJCC stage, poor differentiation). No particular chemotherapy regimen resulted in superior outcomes. Conclusion: Chemotherapy following resection of adenocarcinoma arising from intraductal papillary mucinous neoplasia does not appear to influence recurrence rates, recurrence patterns or survival
