Risk factors of recurrence in TNM stage I colorectal cancer.

Purpose: TNM stage I colorectal cancer (CRC) can recur, although the recurrence rate is low. Few studies have evaluated the risk factors for TNM stage I CRC recurrence. This study aimed to evaluate the TNM stage I CRC recurrence rate, as well as risk factors for recurrence.

Adjuvant oxaliplatin-based chemotherapy effect after treatment of colorectal hepatic metastasis.

Purpose: We aimed to investigate whether adjuvant oxaliplatin-based chemotherapy after treatment for hepatic metastasis affects recurrence or survival and to determine the risk factors for recurrence or survival.

Methods: Forty-six patients who underwent curative treatment for hepatic metastasis from colorectal cancer between July 2009 and December 2017 were included from a retrospectively collected patient database. Curative resection included hepatic resection, radiofrequency ablation (RFA), or a combination of both, followed by adjuvant chemotherapy with oxaliplatin-based chemotherapy.

Case report of periorbital metastasis from rectal cancer.

Introduction: Periorbital metastasis of colorectal cancer is rare. Therefore, herein, we report a patient with rectal cancer who presented with periorbital metastasis without any systemic metastasis.

Patient Concerns: The patient was a 57-year-old man who had a painless nodule on his left eyelid.

Brain metastasis from colorectal cancer: a single center experience.

Purpose: The detection rate of brain metastasis (BM) from colorectal cancer (CRC) is increasing. This study was designed to analyze the clinical features of BM and prognosis according to the therapeutic modalities.

Methods: A total of 19 cases were collected in this study between November 2008 and December 2015.

Clinical Significance of Preoperative Virtual Colonoscopy for Evaluation of the Proximal Colon in Patient With Obstructive Colorectal Cancer.

Purpose: Virtual colonoscopy is the most recently developed tool for detecting colorectal cancers and polyps, but its effectiveness is limited. In our study, we compared the result of preoperative virtual colonoscopy to result of preoperative and postoperative colonoscopy. We evaluated also the accuracy of preoperative virtual colonoscopy in patients who had obstructive colorectal cancer that did not allow passage of a colonoscope.

Impact Of Circulating T Helper 1 And 17 Cells in the Blood on Regional Lymph Node Invasion in Colorectal Cancer.

We hypothesised that the blood levels of immune cells would be related to the progression of colorectal cancer and regional lymph node metastasis. We investigated the association between the blood levels of immune cells and regional lymph node metastasis in colorectal cancer patients. Patients with American Joint Committee on Cancer (AJCC) stages 1 and 2 colorectal cancer were assigned to Early stage group and those with AJCC stages 3 and 4 were assigned to Late stage group.

Undetermined Margins After Colonoscopic Polypectomy for Malignant Polyps: The Need for Radical Resection.

Aim: The aim of the present study was to analyze the clinicopathological features of patients with colorectal cancer (CRC) who underwent radical operation after malignant polyp removal by colonoscopic procedure.

Patients And Methods: Between 2009 and 2013, radical colorectal resection was performed in 50 patients with CRC after colonoscopic polypectomy.

Results: Nine cases (18%) had residual cancer.

Detection of Polyps After Resection of Colorectal Cancer.

Purpose: Because colonoscopy after colorectal cancer surgery is important for detecting synchronous or metachronous colorectal neoplasms, we designed this study to investigate, by using postoperative colonoscopy, the miss rate for and the location of polyps remaining after colorectal cancer surgery.

Methods: In a prospectively-collected patient database, 264 patients were shown to have undergone a colorectal cancer resection between May 2012 and June 2013. Of these, 116 who had received a complete colonoscopy preoperatively and postoperatively were included in this study.

Insertion of totally implantable central venous access devices by surgeons.

Purpose: The aim of this study is to evaluate the results for the insertion of totally implantable central venous access devices (TICVADs) by surgeons.

Methods: Total 397 patients, in whom TICVADs had been inserted for intravenous chemotherapy between September 2008 and June 2014, were pooled. This procedure was performed under local anesthesia in an operation room.

Indeterminate pulmonary nodules in colorectal cancer.

Aim: To investigate the clinicopathologic parameters of pulmonary metastasis in colorectal cancer (CRC) patients after lung operation of indeterminate pulmonary nodules (IPNs).

Methods: From a prospective database of CRC patients, 40 cases that underwent lung operation between November 2008 and December 2012 for suspicious metastatic pulmonary nodules on chest computed tomography (CT) were enrolled. The decision to perform a lung operation was made if the patient met the following criteria: (1) completely resected or resectable primary CRC; (2) completely resectable IPNs; (3) controlled or controllable extrapulmonary metastasis; and (4) adequate general condition and pulmonary function to tolerate pulmonary operation.

Metachronous schwannoma in the colon with vestibular schwannoma.

We experienced a case of vestibular schwannoma and metachronous schwannoma in the colon. A 59-year-old female presented with a 1-month history of hematochezia. She had undergone suboccipital craniectomy resulting in radical subtotal resection, followed by gamma knife radiosurgery for a large left vestibular schwannoma 4 years prior to admission.

Short-term Outcomes of Hand-Assisted Laparoscopic Surgery vs. Open Surgery on Right Colon Cancer: A Case-Controlled Study.

Purpose: This study was designed to evaluate short-term clinical outcomes by comparing hand-assisted laparoscopic surgery with open surgery for right colon cancer.

Methods: Sixteen patients who underwent a hand-assisted laparoscopic right hemicolectomy (HAL-RHC group) and 33 patients who underwent a conventional open right hemicolectomy (open group) during the same period were enrolled in this study with a case-controlled design.

Results: The operation time was 217 minutes in the HAL-RHC group and 213 minutes in the open group (P = 0.

Feasibility of hand-assisted laparoscopic surgery as compared to open surgery for sigmoid colon cancer: a case-controlled study.

Purpose: The aim of this study was to evaluate short-term clinical outcomes by comparing hand-assisted laparoscopic surgery (HALS) with open surgery for sigmoid colon cancer.

Methods: Twenty-six patients who underwent a hand-assisted laparoscopic anterior resection (HAL-AR group) and 52 patients who underwent a conventional open anterior resection during the same period were enrolled (open group) in this study with a case-controlled design.

Results: Pathologic parameters were similar between the two groups.
