Weak stromal Caveolin-1 expression in colorectal liver metastases predicts poor prognosis after hepatectomy for liver-only colorectal metastases.

Loss of stromal Caveolin-1 (CAV1) expression is associated with poor prognosis in various cancers. We evaluated the prognostic value of CAV1 expression of both cancer cells and stromal cells in colorectal liver metastases (CRLM) in patients undergoing hepatectomy. In this retrospective study, 109 patients were enrolled.

Comprehensive Surgical Treatment as the Mainstay of Management in Retroperitoneal Sarcomas: Retrospective Study from Two Non-sarcoma Specialist Centers.

Background/aim: Complete resection, surgical expertise and individualization of patient management in comprehensive oncology centres result in better clinical outcomes in patients presenting with retroperitoneal sarcomas.

Patients And Methods: Clinical outcomes of primary and recurrent retroperitoneal sarcoma resections performed between January 2002 and December 2016 in two large surgical oncology, but non-sarcoma specialist centers, were reviewed to determine the efficacy of complete surgical resection as the principle instrument for treatment. The histological type, tumor size and grade, as well as organ resection, were recorded and subsequently reviewed.

Increased carcinoembryonic antigen (CEA) following neoadjuvant chemotherapy predicts poor prognosis in patients that undergo hepatectomy for liver-only colorectal metastases.

Background: The importance of preoperative chemotherapy in a multimodality management of patients with colorectal liver metastases (CRLM) has been demonstrated. We analyse the carcinoembryonic antigen (CEA) changes following neoadjuvant chemotherapy in patients with CRLM who underwent liver resection.

Methods: The final cohort included 107 eligible patients.

Two cases of gallbladder metastasis from renal cell carcinoma and review of literature.

Background: Renal cell carcinoma accounts for 90% of renal neoplasms and metastatic disease is common. One third of newly diagnosed cases will have synchronous metastases at diagnosis and further 25-50 % will develop metachronous disease.

Case Presentation: This study presents two new cases of gallbladder metastasis from renal cell carcinoma (RCC) from our institution and reviews the published literature.

The ALPPS procedure as a novel "liver-first" approach in treating liver metastases of colon cancer: the first experience in Greek Cypriot area.

Background: Despite recent advances in multimodality and multidisciplinary treatment of colorectal liver metastases, many patients suffer from extensive bilobar disease, which prevents the performance of a single procedure due to an insufficient future liver remnant (FLR). We present a novel indication for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) as a "liver-first" approach when inadequate FLR was faced preoperatively, in a patient with extensive bilobar liver metastatic disease of colon cancer origin.

Case Presentation: A 51-year-old lady was referred to our center due to a stage IV colon cancer with extensive bilobar liver disease and synchronous colon obstruction.

Effective Downsizing of a Large Oesophageal Gastrointestinal Stromal Tumour with Neoadjuvant Imatinib Enabling an Uncomplicated and without Tumour Rupture Laparoscopic-Assisted Ivor-Lewis Oesophagectomy.

Neoadjuvant imatinib for gastrointestinal stromal tumours (GISTs) is increasingly used nowadays. As oesophagectomy is associated with high morbidity and mortality, a preoperative downsizing of an oesophageal GIST to limit the extent of resection would be ideal. Because these tumours are rare and neoadjuvant treatment with imatinib is recent, there is limited literature available regarding neoadjuvant administration of imatinib in patients with oesophageal GISTs.

PEComa in a Young Patient with Known Li-Fraumeni Syndrome.

Perivascular epithelioid cells neoplasms (PEComas) constitute a family of rare tumours which have been reported virtually in all anatomic sites. The histological clarification of the malignant potential of these tumours is still problematic despite the proposed risk stratification systems. Li-Fraumeni syndrome (LFS) is caused by a germline mutation in the TP53 tumour suppressor gene.

Pneumatosis cystoides intestinalis after cetuximab chemotherapy for squamous cell carcinoma of parotid gland.

Pneumatosis intestinalis, defined as gas in the bowel wall, is often first identified on abdominal radiographs or computed tomography (CT) scans. It is a radiographic finding and not a diagnosis, as the etiology varies from benign conditions to fulminant gastrointestinal disease. We report here a case of pneumatosis intestinalis associated with cetuximab therapy for squamous cell carcinoma of head and neck.

The Preoperative Lymphocyte-to-Monocyte Ratio is Prognostic of Clinical Outcomes for Patients with Liver-Only Colorectal Metastases in the Neoadjuvant Setting.

Background: Circulating monocyte-derived, tumor-associated macrophages are associated with a poor prognosis for various cancers. Conversely, circulating lymphocytes are the source of tumor-infiltrating lymphocytes, which are associated with an improved prognosis. This study evaluated the prognostic value of the preoperative blood lymphocyte-to-monocyte ratio (LMR) for patients undergoing hepatectomy for liver-only colorectal metastases.

Early or Delayed Intervention for Bile Duct Injuries following Laparoscopic Cholecystectomy? A Dilemma Looking for an Answer.

Background. To evaluate the effect of timing of management and intervention on outcomes of bile duct injury. Materials and Methods.

Radiofrequency ablation-assisted liver resection: a step toward bloodless liver resection.

Background: Liver resection is currently the most efficient curative approach for a wide variety of liver tumors. The application of modern techniques and new surgical devices has improved operative outcomes. Radiofrequency ablation is used more often for liver parenchymal transection.

Pancreatic perivascular epithelioid cell tumour presenting with upper gastrointestinal bleeding.

PEComa is a family of rare mesenchymal tumours which can occur in any part of the human body. Primary PEComas of the pancreas are extremely rare tumours with uncertain malignant potential. A 17-year-old female was admitted to the hospital due to melena.

Emergency open incarcerated hernia repair with a biological mesh in a patient with colorectal liver metastasis receiving chemotherapy and bevacizumab uncomplicated wound healing.

Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF), often used in combinational chemotherapy regimens for the treatment of patients with colorectal liver metastases. However adverse events have been attributed to the use of bevacizumab including gastrointestinal perforations, thrombotic events, hypertension, bleeding, and wound healing complications. 53-year-old male, with a history of colorectal cancer with liver metastasis, receiving a combination of cytotoxic chemotherapy (FOLFIRI, irinotecan with fluorouracil and folinic acid) with bevacizumab presented as an emergency with an incarcerated incisional hernia.

Neutrophil to lymphocyte ratio predicts pattern of recurrence in patients undergoing liver resection for colorectal liver metastasis and thus the overall survival.

Objective: We investigate the neutrophil to lymphocyte ratio (NLR) as a potential prognostic factor for patients undergoing curative liver resection for colorectal liver metastasis (CRLM).

Methods: We identified patients who underwent liver resection, via our prospectively accumulated surgical database at the Royal Marsden Hospital and The London Clinic, by two liver surgeons (SM and AZK) between January 2005 and December 2012 and patients included had liver resection for CRLM and received preoperative chemotherapy with an NLR > 2.5 considered elevated.

A case of metastatic pancreatic adenocarcinoma with prolonged survival after combination of neoadjuvant FOLFIRINOX therapy and synchronous distal pancreatectomy and hepatectomy.

In this case report we detail the treatment of a patient with pancreatic ductal adenocarcinoma and a solitary liver metastasis who received nine cycles of FOLFIRINOX therapy with favourable response. The patient subsequently underwent synchronous distal pancreatectomy and hepatectomy with an R0 resection followed by three further cycles of FOLFIRINOX. At the last follow-up, 2 years from operation and 28 months from the diagnosis of metastatic pancreatic adenocarcinoma the patient remains disease free.

Combined ultrasonic aspiration and saline-linked radiofrequency precoagulation: a step toward bloodless liver resection without the need of liver inflow occlusion: analysis of 313 consecutive patients.

Background: Hemorrhage is undoubtedly one of the main factors contributing to morbidity and mortality in liver resections. Vascular occlusion techniques are effective in controlling intraoperative bleeding, but they cause liver damage due to ischemia. We evaluated the effectiveness and safety of using a combined technique for hepatic parenchymal transection without liver inflow occlusion.

Addition of bevacizumab to preoperative chemotherapy for colorectal liver metastases does not increase perioperative morbidity and mortality.

Aim: Patients with colorectal liver metastases (CRLM) benefit from liver resection. Bevacizumab is commonly used in these patients resulting in a greater number of patients receiving an operation for a potentially curative liver resection, with initially unresectable liver metastases. Our purpose was to evaluate the effect of preoperative bevacizumab administration on perioperative complications in patients undergoing hepatic resection for CRLM.

Elevated platelet to lymphocyte ratio predicts poor prognosis after hepatectomy for liver-only colorectal metastases, and it is superior to neutrophil to lymphocyte ratio as an adverse prognostic factor.

Recent evidence indicates that inflammation is an essential component of pathogenesis and progression of cancer. In this study, we analysed two indexes of systemic inflammation, the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR), with disease-free survival (DFS) and overall survival (OS) in liver-only colorectal metastases treated with liver resection following neoadjuvant chemotherapy. In this retrospective study, 140 patients were enroled.

Emergency Pancreatoduodenectomy with Preservation of Gastroduodenal Artery for Massive Gastrointestinal Bleeding due to Duodenal Metastasis by Clear Cell Renal Cell Carcinoma in a Patient with Celiac Artery Stenosis.

Duodenal metastasis from renal cell carcinoma is rare, and even rarer is a massive gastrointestinal bleeding from such tumours. Coeliac occlusive disease, although rarely symptomatic, can lead to ischaemic changes with anastomotic dehiscence and leaks when a patient undergoes pancreatoduodenectomy. A 41-year-old man with known metastasis to the adrenal glands and the second part of the duodenum close to the ampulla of Vater from clear cell renal cell carcinoma was admitted to our department due to massive gastrointestinal bleeding from the duodenal metastasis.

Safety of redo hepatectomy for colorectal liver metastases after selective interarterial radiation therapy: a case report.

Surgical resection is the only potentially curative strategy in the treatment of patients with colorectal liver metastases (CLM). Unfortunately, only about 10%-15% of patients are candidates for resection. Preoperative chemotherapy aims to increase the number of patients that may be eligible for liver resection by downsizing liver metastases.

Radiofrequency ablation assisted resection for hepatocellular carcinoma: morbidity, mortality and long term survival.

Purpose: Hepatic resection is the mainstay of the curative treatment of primary hepatic tumors, with constantly improving short and long term results. Radiofrequency ablation (RFA)-assisted liver resection is a relatively new method of transection of the liver parenchyma with favorable intra- and perioperative results. The aim of this study was to investigate the oncological efficacy (long term overall survival/OS and disease free survival/DFS) and to confirm the favorable short term morbidity and mortality.

Isolated jejunal perforation following bicycle handlebar injury in adults: a case report.

The small intestine is the third in frequency intraperitoneal organ which is injured after blunt trauma of the abdomen. In most of the cases, this type of injuries is accompanied by other injuries, which make it more difficult to diagnose. Failure of diagnosis and delay in treating these injuries significantly increase the morbidity and mortality of these patients.
