BACKGROUND Recently, rapid advances have been made in metabolomics-based, easy-to-use early cancer detection methods using blood samples. Among metabolites, profiling of plasma free amino acids (PFAAs) is a promising approach because PFAAs link all organ systems and have important roles in metabolism. Furthermore, PFAA profiles are known to be influenced by(More)
We conducted a feasibility study to examine whether small numbers of cancer cells could be utilised for analysis of the EGFR gene status using the loop-hybrid mobility shift assay, which is a modified heteroduplex technique. Cytology specimens obtained by transbronchial abrasion were successfully used for analysis of the EGFR gene status in 50 of 52 (96.2%)(More)
BACKGROUND Malignant pleural mesothelioma (MPM) is a rare but fatal tumour. Although most MPM patients show pleural effusion at even the early stage, it is hard to diagnose as MPM at the early stage because a sensitive and reliable diagnostic marker for MPM has not been found in plasma or pleural effusion. METHODS In this study, we investigated whether(More)
The rapid aging of the population in Japan has been accompanied by an increased rate of surgery for lung cancer among elderly patients. It is thus an urgent priority to map out a treatment strategy for elderly patients with primary lung cancer. Although surgical resection remains standard treatment for early stage non–small-cell lung cancer (NSCLC), it is(More)
BACKGROUND Current international guidelines recommend the use of platinum-based chemotherapy with thoracic radiotherapy (TRT) for patients with locally advanced non-small-cell lung cancer (NSCLC). METHODS Patients with unresectable stage IIIA or IIIB NSCLC were treated with nedaplatin (NP) at 50 mg m(-2) and irinotecan (CPT) at 60 mg m(-2) on days 1 and 8(More)
An increased prevalence of K-ras oncogene mutation in lung adenocarcinoma has been shown by PCR-primer-introduced restriction with enrichment for mutation alleles (PCR-PIREMA) experiments. In the present study we investigated whether this method is useful for the diagnosis of lung cancer in small pulmonary lesions, which are difficult to diagnose(More)
BACKGROUND We conducted a multicentre feasibility study for single agent long-term S-1 chemotherapy following docetaxel plus cisplatin in patients with curatively resected stage II-IIIA non-small cell lung cancer. METHODS Patients received three cycles of docetaxel (60 mg m(-2)) plus cisplatin (80 mg m(-2)) and then received S-1 (40 mg m(-2) twice daily)(More)
A feasibility study on the vibratory perception threshold (VPT) in normal volunteers was conducted to detect anti-cancer drug induced peripheral neuropathy. The VPT was found to increase with age. The mean VPT in the main hand in 25 normal volunteers was significantly higher than in the other hand. No variation of VPT was observed in one day or one week.(More)
Docetaxel monotherapy is one of the standard treatments for non-small-cell lung cancer in elderly patients. The addition of bevacizumab to docetaxel seems promising; however, the feasibility of this combination has not been investigated in such patients. Patients with advanced non-squamous non-small-cell lung cancer aged 70 years or older who had not(More)
