Objective: To determine the prognostic significance of the synchronous colorectal cancer (S-CRC) on survival and recurrence rate.
Methods: Authors conducted an analysis of 90 colorectal adenocarcinoma patients who received a curative (R0) resection with a full course of standard adjuvant treatment. A total of 45 patients diagnosed with S-CRC at the time of initial presentation were individually matched to a group of 45 solitary CRC patients in pair at a ratio of 1:1.
Objective: This study aimed to determine whether microvessel density (MVD) in the tumor tissues could be a potential predictive marker for vascular invasion (VI).
Methods: Surgical specimens of 73 patients with colorectal adenocarcinoma in Phramongkutklao Hospital were analyzed. Tissues of patients receiving preoperative radiation or prior anti-angiogenic therapy were excluded.
Objective: This study aimed to assess whether pretreatment tumor tissue microvessel density (MVD) could be a potential predictive marker for Mandard response in LARC treated with nCRT.
Methods: A retrospective analysis was performed in pretreatment paraffin-embedded specimens of 31 pathologically confirmed rectal adenocarcinoma. All patients received nCRT and subsequent total mesorectal resection.
Objective: This study aimed to compare the clinico-pathologic features, recurrence rate and disease-free survival between colorectal cancers (CRCs) with synchronous advanced colorectal neoplasia (SCN) and solitary CRCs to determine the prognostic significance of SCN.
Methods: A retrospective review of prospectively collected data of patients with CRCs was conducted in Phramongkutklao Hospital from January 2009 to December 2014. Patients were categorized in 3 groups: 1) solitary CRCs, 2) CRCs with advanced colorectal adenomas (ACAs) but having no another cancer and 3) synchronous colorectal cancers (S-CRCs) with or without ACAs.
Objective: Determine the relationship between vascular endothelial growth factor (VEGF) expression and microvascular density (MVD) in primary colorectal cancer specimens including the prognostic value by evaluating the correlation between various common reported prognostic histopathologic indictors and these two angiogenic parameters. The Inter-observer reliability on VEGF and MVD measurement was also determined.
Material And Method: Anti-VEGF and anti-factor CD34 monoclonal antibodies immunohistochemical staining was performed in 40 randomly selected formalin-fixed paraffin-embedded colorectal cancer specimens of non-stage-IV patients who underwent curative resection using.
Background: The presence of distant metastases from colorectal cancer (CRC) does not preclude curative treatment. Early detection of pulmonary metastases at a potentially curable stage could improve survival. The aim of the present study was to assess the prognostic significance of commonly reported clinicopathologic features to identify high-risk patients who would likely benefit from more intensive chest surveillance for pulmonary metastases.

Objective: Identify factors increasing the risk of incisional SSI that lead to the development of a more efficient tool for predicting and comparing surgical site infection rates among surgeons and institutions performing the same type of procedure for colorectal surgery patients.
Material And Method: The authors conducted a prospective incisional SSI surveillance in 229 consecutive patients who underwent open colon and rectal resections performed in Phramongkutklao Hospital between October 1, 2008 and September 30, 2010.
Objective: To compare analgesic effectiveness, postoperative pain, complications, and patients' satisfaction between two randomly allocated groups--one group that had local perianal nerve block and another group that had spinal block following closed hemorrhoidectomy.
Material And Method: Sixty-seven patients underwent elective hemorrhoidectomy. Of these, 33 were randomly allocated to receive spinal anesthesia (SA) while 34 received perianal local analgesia (LA) with bupivacaine.
