Colorectal cancer has become one of the most common malignant tumors that affects Chinese's health. Recurrence and metastasis are main reasons for death of colorectal cancer patients. Making up individualized and comprehensive therapeutic strategy according to patients' specific matters is the developmental direction of diagnosis and treatment for colorectal cancer. Only if standardize clinical pathway, perfect postoperative follow-up system, and accelerate research development on biomarkers, individualized therapy of colorectal cancer can be accomplished.

BACKGROUND/AIMS: Elderly patients (≥ 80 years) with colorectal cancer (CRC) tend to avoid active treatment at the time of diagnosis despite of recent advances in treatment. The aim of this study was to determine treatment propensity of elderly patients aged ≥ 80 years with CRC in clinical practice and the impact of anticancer treatment on overall survival (OS). METHODS: Medical charts of 152 elderly patients (aged ≥ 80 years) diagnosed with CRC between 1998 and 2012 were retrospectively reviewed. Patients’ clinical characteristics, treatment modalities received, and clinical outcome were analyzed. RESULTS: Their median age was 82 years (range, 80 to 98). Of 152 patients, 148 were assessable for the extent of the disease. Eighty-two of 98 patients with localized disease and 28 of 50 patients with metastatic disease had received surgery or chemotherapy or both. Surgery was performed in 79 of 98 patients with localized disease and 15 of 50 patients with metastatic disease. Chemotherapy was administered in only 24 of 50 patients with metastatic disease. Patients who received anticancer treatment according to disease extent showed significantly longer OS compared to untreated patients (localized disease, 76.2 months vs. 15.4 months, p = 0.000; metastatic disease, 9.9 months vs. 2.6 months, p = 0.001). Along with anticancer treatment, favorable performance status (PS) was associated with longer OS in multivariate analysis of clinical outcome. CONCLUSIONS: Elderly patients aged ≥ 80 years with CRC tended to receive less treatment for metastatic disease. Nevertheless, anticancer treatment in patients with favorable PS was effective in prolonging OS regardless of disease extent.

PURPOSE: The presence of gastrointestinal (GI) cancer and its treatment might aggravate patient nutritional status. Malnutrition is one of the major factors affecting the postoperative course. We evaluated changes in perioperative nutritional status and risk factors of postoperative severe malnutrition in the GI cancer patients. MATERIALS AND METHODS: Nutritional status was prospectively evaluated using patient-generated subjective global assessment (PG-SGA) perioperatively between May and September 2011. RESULTS: A total of 435 patients were enrolled. Among them, 279 patients had been diagnosed with gastric cancer and 156 with colorectal cancer. Minimal invasive surgery was performed in 225 patients. PG-SGA score increased from 4.5 preoperatively to 10.6 postoperatively (p<0.001). Ten patients (2.3%) were severely malnourished preoperatively, increasing to 115 patients (26.3%) postoperatively. In gastric cancer patients, postoperative severe malnourishment increased significantly (p<0.006). In univariate analysis, old age (>60, p<0.001), male sex (p=0.020), preoperative weight loss (p=0.008), gastric cancer (p<0.001), and open surgery (p<0.001) were indicated as risk factors of postoperative severe malnutrition. In multivariate analysis, old age, preoperative weight loss, gastric cancer, and open surgery remained significant as risk factors of severe malnutrition. CONCLUSION: The prevalence of severe malnutrition among GI cancer patients in this study increased from 2.3% preoperatively to 26.3% after an operation. Old age, preoperative weight loss, gastric cancer, and open surgery were shown to be risk factors of postoperative severe malnutrition. In patients at high risk of postoperative severe malnutrition, adequate nutritional support should be considered.

Chyle leak is a rare complication after abdominal surgery. According to the statistical results from our center, we summarized the experiences in the diagnosis, treatment and prevention of abdominal chyle leak after radical resection of colorectal cancer. Early prevention, early diagnosis, and early treatment may result in earlier recovery, shorter hospital stay, lower incidence, and better prognosis.

Colorectal cancer is one of the most common malignancies in human, and colorectal liver metastasis (CLM) is one of the most common leading causes of death in these patients. In recent years, along with the update of diagnosis and treatment concept and advancement of operative technique, more and more patients with CLM get surgical treatment opportunities and the outcomes are improved. In clinical practice of CLM, depending on evidence-based medicine, standardized diagnosis and treatment is particularly important, which includes diagnosis and treatment by multidisciplinary team, accurate evaluation of the resectability of CLM, standardized surgical resection and essential comprehensive treatment.

OBJECTIVETo summarize the clinical features and surgical methods for colorectal cavernous hemangioma in China.

METHODSData of 4 cases in Peking Union Medical College Hospital and 54 cases with colorectal cavernous hemangioma from 1979 to 2006 reported in Chinese literatures were analyzed retrospectively, including clinic manifestations and surgery treatment.

RESULTSThe incidence of male to female was 1.0:1.0, and 43.1% of the patients had their first onset of recurrent rectal bleeding in early childhood. Colonoscopy, rectal CT scan and MRI were the accurate methods for the diagnosis (100%). 91.4% of the patients had diffuse infiltrative lesions and 8.6% of the patients had localized lesions. 82.8% of the patients underwent surgical treatment while 3.5% of the patient did not received treatment.

CONCLUSIONSColonoscopy is the first choice for the diagnosis of colorectal cavernous hemangioma. Local resection should be performed for the localized cavernous hemangioma. Sigmoid colon and rectum resection with coloanal anastomosis is suitable for the diffuse and infiltrative colorectal cavernous hemangioma.

Endoscopic submucosal dissection (ESD) is an useful therapeutic technique for large gastrointestinal epithelial tumors that it provides an en bloc resection. Although there is some controversy about the role of ESD for colorectal lesions, for large lesions in the distal rectum, ESD has the advantage of preserving anal function. However, the large amount of insufflating gas used during the procedure can cause severe abdominal pain and discomfort. Moreover, high intra-luminal pressure caused by a by large amount of gas can cause a micro-perforation. There is no consensus as to whether ESD is the optimal treatment for synchronous large colorectal laterally spreading tumors (LSTs) that cannot be removed en-bloc by conventional endoscopic mucosal resection. Here, a case with two neighboring synchronous large LSTs, one located in the rectum and the other in the distal sigmoid colon, were sequentially removed by separate ESD procedures performed on two consecutive days in a patient who could not tolerate a long procedure.

OBJECTIVETo investigate the outcomes of surgical treatment and the prognostic factors of long-term survival for obstructing left colorectal cancer.

METHODSClinicopathological and follow-up data of 93 patients with obstructing left colorectal cancer undergoing surgical treatment from January 2001 to December 2006 in the Affiliated Hospital of Medical College of Qingdao University were analyzed retrospectively.

RESULTSThere were 53 males and 40 females. The median age was 61 years old. Fifty-one patients had concurrent medical condition. Radical resection was performed in 67 patients, including one-stage resection (n=21), Hartmann procedure (n=35), and Miles procedure (n=11). Surgery was palliative in 26 patients, including diverting stoma (n=14), bypass surgery (n=7), and palliative resection (n=5). All the 93 patients were followed up. The 1-, 3-, and 5-year survival rates were 94%, 59%, and 38%, respectively. Univariate and multivariate analyses showed that radical resection, TNM staging, and preoperative level of carcinoembryonic antigen were independent prognostic factors (all P<0.05).

CONCLUSIONSRadical resection, TNM stage, and preoperative CEA level are prognostic factors of obstructing left colorectal cancer. Early diagnosis, radical resection, and selection of appropriate surgical procedure are helpful to prolong survival time of patients with obstructing left colorectal cancer.
