High-sensitivity Detection of Micrometastases Generated by GFP Lentivirus-transduced Organoids Cultured from a Patient-derived Colon Tumor

Despite current advances in human colorectal cancer (CRC) treatment, few radical therapies are effective for the late stages of CRC. To overcome this ...

Systemic inflammatory responses have been reported to be independent predictors of cancer-specific survival in colorectal cancer. The Glasgow Prognostic Score (GPS), which is an inflammation-based prognostic factor, is defined by the presence of elevated C-reactive protein and hypoalbuminemia. The purpose of this study was to estimate whether GPS can be a prognostic factor in patients undergoing curative surgery for colorectal cancers.

Glasgow prognostic score as a prognostic factor in patients undergoing curative surgery for colorectal cancer.

The patient was a 68-year-old man who was admitted to our hospital with a liver tumor. Abdominal ultrasonography and computed tomography revealed a liver tumor 30 mm in diameter. On colonoscopy, a pedunculated tumor with a central depression (20 mm in diameter) was observed in the ascending colon, and this tumor was considered to be invading deeply into the submucosal layer. Right hemicolectomy with D3 lymphadenectomy and partial hepatectomy were performed simultaneously. On histopathological examination of the resected specimen, the tumor was a well-differentiated tubular adenocarcinoma with 3,000 μm invasion of the submucosal layer. The liver tumor showed histological findings similar to those of the primary colorectal carcinoma. The pathological stage according to the 7th edition of the TNM classification was stage IV (T1N0M1). Nine months after the operation, computed tomography revealed hepatic hilar lymph node metastases and a great deal of ascites. The patient ultimately died 14 months after the operation. 

T1 colorectal cancer with synchronous liver metastasis.

Because the TNM system disregards the number of lymph nodes dissected and inter-individual differences exist in the number of regional lymph nodes, the lymph node ratio (LNR), which is estimated by dividing the number of metastatic lymph nodes by the number of dissected lymph nodes, has been proposed as a prognostic factor in recent years. The purpose of the present study is to examine the validity of predicting prognosis using the LNR in node-positive colon cancer.

The validity of predicting prognosis by the lymph node ratio in node-positive colon cancer.

Therapy comprising 5-fluorouracil, levofolinate, and oxaliplatin is currently the most common chemotherapy for colorectal cancer. We experienced a successful case of advanced colon cancer and recurrent breast cancer with 5-fluorouracil, levofolinate, and oxaliplatin therapy.
