Abstract. The aim of the present study was to estimate the effect of the perioperative administration of probiotics in patients undergoing colorectal cancer (CRC) surgery. The study focused on a total of 156 consecutive surgeries carried out from among all the elective CRC surgeries performed between

Numbness and pain are currently evaluated using subjective methods such as the visual analogue scale (VAS). PainVision (PV) is an analytical instrument that was designed to quantitatively assess sense perception and nociception in patients. Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most important adverse events that renders prolonged chemotherapy difficult. To assess the features of CIPN, we aimed to compare PV methods with existing methods. A total of 73 patients received oxaliplatin for metastatic colorectal cancer. Registered patients included 37 men and 36 women in the range of 37 to 89 years (median 70). CIPN was evaluated a total of 483 times (median per patient six times). Our study examined the correlation between evaluation methods of CIPN using VAS and PV, respectively. The average VAS (hand), VAS (foot) and PV scores of CIPN were 18.4 (range: 0–100), 23.8 (range: 0–100), and 24.7 (range: 0–496), respectively. VAS (hand), VAS (foot), and FACT/GOG-NTX (NTX2, NTX4 and NTX8) were significantly correlated with PV. PV showed no correlation with a Disk-Criminator or the monofilament test used as a quantitative evaluation. The evaluation of CIPN is complex, and further improvement is required for evaluation with PV.

Numbness and pain are currently evaluated using subjective methods such as the visual analog scale (VAS). However, because assessment of pain can vary greatly depending on the mood and physical state of the patient at the time of assessment, it is best to evaluate pain objectively. pain vision PS-2100 (PV) is an analytical instrument that was designed to quantitatively and objectively assess sense perception and nociception in patients. The present study examined the correlation of subjective and objective assessment of oxaliplatin-induced peripheral neuropathy (PN) using VAS and PV, respectively. The mean VAS and PV scores of PN were 20.5 (range 0–100) and 27.9 (range 0–416), respectively. The partial correlation coefficient was 0.274 (p = 0.0003). No strong correlation was observed between the results and a weak correlation was observed between VAS and PV.

In recent years, therapeutic drug monitoring (TDM) of intravenous administration of 5-fluorouracil (5-FU) has resulted in reduced toxicity and improved efficacy. Prodrugs of 5-FU were developed to reduce toxicity, extend the duration of action, and increase tumour selectivity of 5-FU. These drugs are important in daily practice because of their ease of administration. Dose adjustment of 5-FU prodrugs by TDM is expected to reduce its toxicity and improve its efficacy. This review focuses on data from a recent study of personalized treatment using TDM of 5-FU and its prodrugs.

A 61-year-old male, who had been admitted to another hospital due to disseminated intravascular coagulation (DIC), was referred to our hospital. Total colonoscopy, abdominal dynamic CT and positron-emission tomography revealed bone metastasis and multiple lymphocytic metastases from transverse colon cancer in addition to disseminated carcinomatosis of the bone marrow (DCBM). We immediately performed chemotherapy with XELOX + bevacizumab and denosumab against DCBM from transverse colon cancer in order to avoid radical surgery. In addition, we initiated the administration of recombinant human soluble thrombomodulin for 1 week to treat DIC. The patient was able to tolerate and receive 4 cycles of chemotherapy without any severe side effects. After receiving the 4 cycles of treatment, he recovered from DIC, and the bone and multiple lymphocytic metastases disappeared.
