Chemotherapy-induced peripheral neuropathy(CIPN)is one of chemotherapy's common and disabling adverse effects. It may be caused by many chemotherapeutic agents including the taxanes(paclitaxel, docetaxel), the vinca alkaloids(vincristine, vinorelbine, vinblastine), the platinum analogues(cisplatin, carboplatin, oxaliplatin), bortezomib and thalidomide, among others. ⋯ At the present time, no agent has shown enough solid beneficial evidence to be recommended for the treatment or/prophylaxis of CIPN. The standard of care for CIPN includes awareness and early detection of neuropathy, and dose reduction and/or discontinuation of the problematic agents.

[High-throughput screening method of KRAS mutations at codons 12 and 13 in formalin-fixed paraffin-embedded tissue specimens of metastatic colorectal cancer].
Clinical studies overseas using the therapeutic anti-EGFR monoclonal antibodies, cetuximab or panitumumab against metastatic colorectal cancer(mCRC), have revealed KRAS mutations as a negative predictive marker of response. Accordingly, the Ministry of Health, Labour and Welfare in Japan approved medical reimbursement of the KRAS mutation test in April 2010. Anti-EGFR monoclonal antibody therapies are now used as first-line treatment for patients with mCRC. ⋯ Here we evaluated the basic performance of our system and confirmed its high specificity and reproducibility in detecting KRAS mutations at codons 12 and 13 in both plasmid DNAs carrying mutant KRAS genes and formalin-fixed paraffin-embedded tissues from mCRC patients. We demonstrated the KRAS mutation status in paraffin-embedded tissues of mCRC and confirmed that the results were comparable to those of the direct sequencing method. Our high-throughput method has an advantage in simultaneous analysis of multiple mutations in one well of 96-well PCR plates, and will advance the KRAS mutation test in clinical laboratories.

Case Reports[Oxycodone and pregabalin using transdermal fentanyl patch provided relief of symptoms for postherpetic neuropathic pain in a patient with non-small cell lung cancer].
This paper presents a man in his 70's with non-small cell lung cancer (cT3N2M0, Stage III A) after chemoradiation therapy during follow-up visits. He was referred to the department of palliative care 1 month after the occurrence of herpes zoster, because of pain. Opioids (transdermal fentanyl patch and rapid-release oxycodone) were administered for his cancer pain previously. ⋯ The dose of rapid-release oxycodone was increased and controlled-release oxycodone was added. This provided for marked pain relief. We conclude that administration of pregabalin as an analgesic adjuvant, and oxycodone, which is an opioid, should be considered in the treatment of cancer patients without improvement of neuropathic pain from herpes zoster through use of the transdermal fentanyl patch.

[The efficacy of aprepitant and palonosetron on cisplatin doublet in lung cancer].
Nausea and vomiting are major adverse reactions in cancer chemotherapy, and affect quality of life (QOL). We performed a retrospective study that examined the efficacy of aprepitant and palonosetron for chemotherapy-induced nausea and vomiting (CINV) on patients taking cisplatin doublets for lung cancer. The study subjects were 73 patients. ⋯ Significantly better efficacy was seen in the 5-HT(3) group and A group in the complete suppression rate of vomiting, and in the need of rescue medication rates on delayed-onset emesis. The cost of antiemesis was 19, 735 yen for the 5-HT(3) group, 32, 252 yen for the A group and 15, 557 yen for the A+P group. In conclusion, it was suggested that concurrent administration of palonosetron, aprepitant and dexamethasone for CINV on cisplatin doublet in lung cancer is a clinically useful treatment that might reduce the economic burden on patients.

Case Reports[Three cases effectively treated with S-1 therapy for liver metastasis of breast cancer in long term].
We experienced 3 cases of anti-cancer drug-resistant recurrent breast cancer with liver metastasis showing significant improvement by S-1. Almost all patients maintained the full dose through the whole course of treatment, and the drug showed good tolerability. Furthermore, long-term therapeutic efficacy(more than 2 years)and QOL have been maintained for all patients. We concluded that S-1 is not only effective as a therapeutic agent, but is safe and maintains QOL.
