peripheral blood and regional lymphatic nodes by using lunx mRNA specific reverse transcription-polymerase chain reaction (RT-PCR). Methods: RT-PCR was used to detect lunx mRNA in peripheral blood of 26 patients with lung cancer. We also detected 44 regional lymphatic nodes obtained from 25 patients with lung cancer who underwent curative lobectomy. All the 44 regional lymphatic nodes were also examined by histopa',hology. Micrometastatic tumor cells in the peripheral blood and regional lymphatic nodes were semiquantitatively determined with the ratio of lunx band intensity to the glyceraldehydes-3-phosphate dehydrogenase band intensity. Results: The positive detection rate of lunx mRNA in peripheral blood for non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) patients were 60% (12/20) and 67% (4/6) respectively. 16 (36.4%) of regional lymphatic nodes from 44 lung cancer patients were positive by RT-PCR while 6 (13.6%) were positive by histopathology (x2=6.06, P=0.014). However, no blood samples and lymphatic nodes from patients with benign pulmonary diseases or normal volunteers were positive for lunx mRNA. The positive detection rate of lunx mRNA in bone marrow of NSCLC Received date: December 17, 2001; Accepted date: February 1, 2002. Foundation item: This work was supported by a grant from the Department of Public Health of Jiangsu Province (No. Z9709). *Author to whom correspondence should be addressed.

Present address: Department of Radiation Oncology, Peking University School of Oncology, Beijing 100036 amd SCLC patients were 65% (13120) and 67% (4/6) respectively. Conclusion: RT-PCR amplification of lunx mRNA is an sensitive and specific means to detect early haematogenous and regional lymphatic nodes dissemination of cancer cells for patients with lung cancer.

N2 - We investigate the spectral properties of quark-quark-gluon correlators and use this to study gluonic pole matrix elements. Such matrix elements appear in principle both for distribution functions such as the Sivers function and fragmentation functions such as the Collins function. We find that for a large class of spectator models, the contribution of the gluonic pole matrix element for fragmentation functions vanishes. This result is important in the study of universality for fragmentation functions.
