BACKGROUND: The increasing use of laparoscopic surgery for advanced gastrointestinal cancer raises concerns about intra-peritoneal tumor spread. Prevention of peritoneal dissemination is extremely important but a preventive modality is lacking. The aim of this study was to examine a novel approach (hyperthermic CO2 insufflation, HT-CO2) for preventing peritoneal dissemination during laparoscopic surgery. METHODS: A peritoneal dissemination model was established in Balb/c nu/nu mice by intraperitoneal injection of human colon cancer cells (SW1116, 1×106)...

It has been reported that many patients with lung metastasis of colorectal cancer (CRC) underwent chemotherapy with fluorouracil, folinic acid, oxaliplatin, irinotecan, or capecitabine. There is a small number of reports about the capecitabine and irinotecan (XELIRI) plus bevacizumab (BV) therapy for patients with metastatic CRC in Japan. We report a case of successful BV+XELIRI therapy for rectal cancer with multiple lung metastases as first-line chemotherapy. A 53-year-old female presented with advanced rectal cancer and metastatic lung tumors...

BACKGROUND: The benefit of adjuvant chemotherapy occurs with early initiation, but is commonly delayed due to postoperative complications. Minimally invasive surgery is proven to significantly reduce complications and hospital length of stay. This study compares open versus laparoscopic liver resection in patients requiring adjuvant chemotherapy. METHODS: 120 consecutive patients with metastatic colorectal liver cancer who underwent liver resection between 2007 through 2012 were reviewed from an IRB prospective database...

AIM: Mutations in K-ras codon 12 and 13 of exon 2 are known to affect prognosis and impart resistance to anti-epidermal growth factor monoclonal antibody therapy in colorectal carcinoma (CRC). Our aim was to investigate the utility value of modified mismatch polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay to detect mutation in K-ras codons of CRC patients and to relate the mutational status to liver metastasis. METHODOLOGY: Mismatch PCR-RFLP was developed to detect K-ras mutations in DNA isolated from paraffinized tumor tissue of thirty CRC patients...

: 120 Background: Twenty-five percent of patients with colorectal cancer will present with unresectable disease. Palliative surgery has been shown to improve symptom control and improve patient satisfaction as well as demonstrate improved cost and decreased healthcare utilization. However, it is unclear what factors influence use. We sought to determine patient and hospital factors associated with palliative surgery use in advanced colorectal cancers. METHODS: Using the National Cancer Data Base (NCDB) Participant User File from 2006 to 2012, 162,967 patients with metastatic colorectal cancer were identified...

Adrenal metastasis from colorectal cancer occurs in the presence of multiple synchronous metastases at other sites. We report a case of heterochronous solitary adrenal metastasis from rectal cancer. A 55-year-old man underwent anterior resection with D3 lymph node dissection for rectal cancer. The pathological stage of the tumor was III b, and adjuvant chemotherapy with mFOLFOX6 was administered for 6 months. Eighteen months after surgery, abdominal computed tomography(CT) revealed right solitary adrenal metastasis...

In recent years, several colorectal patients with pulmonary and hepatic metastasis, if resectable, have been found to experience long-term survival. In the present study, we extracted predictive factors, selected patients for whom a good prognosis could be anticipated, and examined the indications for surgery. From January 1986 to December 2014, we conducted a multivariate analysis of 18 patients who underwent surgical resection for pulmonary and hepatic metastases, with overall survival(OS)as the dependent variable, and clinicopathological factors as explanatory variables...

Laparoscopic major hepatectomy is a common procedure that has been reported frequently; however, laparoscopic resection of centrally located tumors involving segments 4, 5, and 8 remains a technically difficult procedure because it requires 2 transection planes and dissection of numerous branches of the hepatic vein and glissonean capsule compared to hemi-hepatectomy. Here, we present 7 cases of totally laparoscopic right anterior sectionectomy (Lap-RAS) and 3 cases of totally laparoscopic central bisectionectomy (Lap-CBS)...

Colorectal cancer is a prevalent malignancy worldwide, and investigations are required to elucidate the underlying carcinogenic mechanisms. Amongst these mechanisms, de novo carcinogenesis and the adenoma to carcinoma sequence, are the most understood. Metastasis of colorectal cancer to the liver often results in fatality, therefore, it is important for any associated risk factors to be identified. Regarding the treatment of the disease, it is important to manage not only the primary colorectal tumor, but also the liver metastases...

BACKGROUND: Treatment of preoperative anaemia is recommended as part of patient blood management, aiming to minimize perioperative allogeneic red blood cell transfusion. No clear evidence exists outlining which treatment modality should be used in patients with colorectal cancer. The study aimed to compare the efficacy of preoperative intravenous and oral iron in reducing blood transfusion use in anaemic patients undergoing elective colorectal cancer surgery. METHODS: Anaemic patients with non-metastatic colorectal adenocarcinoma were recruited at least 2 weeks before surgery and randomized to receive oral (ferrous sulphate) or intravenous (ferric carboxymaltose) iron...

Colorectal cancer (CRC) is one the greatest contributors to cancer related mortality. Although 5 year survival rate for patients at the early stage of CRC (stages I and II) is above 60%, more than 50% of patients are diagnosed at or beyond stage III when distant metastasis has already occurred, in which case 5 year survival rate drops to 10%. Chemotherapeutic intervention coupled with surgery is the backbone of metastatic CRC treatment and the only means of enhanced survival. For decades following its discovery, an antimetabolite 5-fluorouracil (5-FU) was the only chemotherapeutic agent available to successfully improve 12 month survival in CRC patients...

Colorectal cancer (CRC) is a malignant disease whose incidence and mortality rates are greatly influenced by environmental factors. Under-treatment of CRC such as a poor diagnostic evaluation, less aggressive surgery, less intensive chemotherapy results in metastasizing of the primary tumor cells and recurrence of cancer. Prolonged chemotherapy treatment against cancer is hazardous to the patients, which also limits its use in cancer therapy. Current research in developing a novel anti-cancer agent, direct towards finding a better anti-metastatic and an anti-invasive drug with reduced side effects...

BACKGROUND: The number of lymph node retrieved in the surgical specimen is important for tumor staging and has paramount impact on prognosis in colorectal cancer and imitates the adequacy of lymph node surgical clearance. The paucity of lymph node yields in patients undergoing resection after preoperative chemo radiotherapy (CRT) in rectal cancer has seen. Lower total number of lymph nodes in the total mesoractal excision (TME) specimen after CRT, could a marker of better tumor response...
