Oesophageal Metastasis from Colorectal Cancer

Metastasis to the oesophagus is most frequently described in association with lung or breast cancer. Diagnosis is frequently complicated as often only normal tissue is present in endoscopic biopsy specimens. Although oesophagectomy for metastasis has been described, few patients are suitable for curative resection. We report the case of a 62-year-old man who developed an oesophageal metastasis from colorectal cancer and review the available literature

Ten-year experience in the management of gallbladder cancer from a single hepatobiliary and pancreatic centre with review of the literature

Background. There is no consensus regarding the optimum surgical approach to gallbladder cancer. This study reviews the management of gallbladder cancer in a single unit. Methods. Retrospective study of 73 consecutive patients diagnosed with gallbladder cancer. Twenty-three patients underwent surgery with curative intent (surgical group), 28 patients underwent exploratory surgery but had inoperable disease (surgically inoperable group) and 22 patients had inoperable disease radiologically (radiologically inoperable group). Within the surgical group, nine patients (cholecystectomy group) were diagnosed with gallbladder cancer after routine cholecystectomy. Results. The inoperable groups had significantly higher bilirubin and alkaline phosphatase (ALP) than the surgical group (p=0.02 and p<0.01, respectively). Age>68, white cell count (WCC)>7.6×109/L, platelet>345×109/L, bilirubin>16 mol/L, ALP >124 iu/L and sodium =137 mmol/L were markers of inoperability. Age, haemoglobin and neutrophil:lymphocyte ratio (NLR) were predictors for survival following surgery (p=0.04, p=0.01 and p<0.01, respectively). The surgical and cholecystectomy groups had significantly higher median survivals than the surgically and radiologically inoperable groups (18.97 and 26.17 months versus 5.03 and 12.20 months, p=0.04). Conclusion. Curative surgical resection of gallbladder cancer improved survival. Exploratory laparotomy which revealed inoperable disease reduced survival. Preoperative WCC, platelet, bilirubin and ALP may be used as additional discriminators during the investigation and work up prior to surgery

Predictors of actual five-year survival and recurrence after pancreatoduodenectomy for ampullary adenocarcinoma: results from an international multicentre retrospective cohort study

Background: pancreatoduodenectomy (PD) is recommended in fit patients with a resectable ampullary adenocarcinoma (AA). We aimed to identify predictors of five-year recurrence/survival.Methods: data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD patients with a confirmed head of pancreas or periampullary malignancy (June 1st, 2012-May 31st, 2015). Patients with AA who developed recurrence/died within five-years were compared to those who did not.Results: 394 patients were included and actual five-year survival was 54%. Recurrence affected 45% and the median time-to-recurrence was 14 months. Local only, local and distant, and distant only recurrence affected 34, 41 and 94 patients, respectively (site unknown: 7). Among those with recurrence, the most common sites were the liver (32%), local lymph nodes (14%) and lung/pleura (13%). Following multivariable tests, number of resected nodes, histological T stage &gt; II, lymphatic invasion, perineural invasion (PNI), peripancreatic fat invasion (PPFI) and ≥1 positive resection margin correlated with increased recurrence and reduced survival. Furthermore, ≥1 positive margin, PPFI and PNI were all associated with reduced time-to-recurrence.Conclusions: this multicentre retrospective study of PD outcomes identified numerous histopathological predictors of AA recurrence. Patients with these high-risk features might benefit from adjuvant therapy.</p

Serious complications of pancreatoduodenectomy correlate with lower rates of adjuvant chemotherapy: results from the recurrence after Whipple's (RAW) study

Introduction: adjuvant chemotherapy (AC) can prolong overall survival (OS) after pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). However, fitness for AC may be influenced by postoperative recovery. We aimed to investigate if serious (Clavien-Dindo grade ≥ IIIa) postoperative complications affected AC rates, disease recurrence and OS.Materials and methods: data were extracted from the Recurrence After Whipple's (RAW) study (n = 1484), a retrospective study of PD outcomes (29 centres from eight countries). Patients who died within 90-days of PD were excluded. The Kaplan-Meier method was used to compare OS in those receiving or not receiving AC, and those with and without serious postoperative complications. The groups were then compared using univariable and multivariable tests.Results: patients who commenced AC (vs no AC) had improved OS (median difference: (MD): 201 days), as did those who completed their planned course of AC (MD: 291 days, p &lt; 0.0001). Those who commenced AC were younger (mean difference: 2.7 years, p = 0.0002), more often (preoperative) American Society of Anesthesiologists (ASA) grade I-II (74% vs 63%, p = 0.004) and had less often experienced a serious postoperative complication (10% vs 18%, p = 0.002). Patients who developed a serious postoperative complication were less often ASA grade I-II (52% vs 73%, p = 0.0004) and less often commenced AC (58% vs 74%, p = 0.002).Conclusion: in our multicentre study of PD outcomes, PDAC patients who received AC had improved OS, and those who experienced a serious postoperative complication commenced AC less frequently. Selected high-risk patients may benefit from targeted preoperative optimisation and/or neoadjuvant chemotherapy.</p

Does an extensive diagnostic workup for upfront resectable pancreatic cancer result in a delay which affects survival? Results from an international multicentre study

Backgrounds/aims: pancreatoduodenectomy (PD) is recommended in fit patients with a carcinoma (PDAC) of the pancreatic head, and a delayed resection may affect survival. This study aimed to correlate the time from staging to PD with long-term survival, and study the impact of preoperative investigations (if any) on the timing of surgery.Methods: data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD outcomes. Only PDAC patients who underwent an upfront resection were included. Patients who received neoadjuvant chemo-/radiotherapy were excluded. Group A (PD within 28 days of most recent preoperative computed tomography [CT]) was compared to group B (&gt; 28 days).Results: a total of 595 patents were included. Compared to group A (median CT-PD time: 12.5 days, interquartile range: 6-21), group B (49 days, 39-64.5) had similar one-year survival (73% vs. 75%, p = 0.6), five-year survival (23% vs. 21%, p = 0.6) and median time-todeath (17 vs. 18 months, p = 0.8). Staging laparoscopy (43 vs. 29.5 days, p = 0.009) and preoperative biliary stenting (39 vs. 20 days, p &lt; 0.001) were associated with a delay to PD, but magnetic resonance imaging (32 vs. 32 days, p = 0.5), positron emission tomography (40 vs. 31 days, p &gt; 0.99) and endoscopic ultrasonography (28 vs. 32 days, p &gt; 0.99) were not.Conclusions: although a treatment delay may give rise to patient anxiety, our findings would suggest this does not correlate with worse survival. A delay may be necessary to obtain further information and minimize the number of PD patients diagnosed with early disease recurrence.</p
