Background: Patients with intermediate- or high-grade non-Hodgkin's lymphoma (NHL) who have a relapse or refractoriness after initial standard chemotherapy generally have a poor prognosis. Conventional salvage treatment can induce lengthy remission. It is, however, not generally agreed that long-term survival has been expected in patients receiving salvage chemotherapy. The combination of high dose therapy and autologous stem cell transplantation has been considered promising in refractory or relapsed patients with NHL. Methods: The response rate and survival (disease-free and overall survival) of 15 patients with relapsed or refractory NHL who only received salvage chemotherapy was compared with those of 14 patients who has been assigned to receive high dose therapy and autologous stem cell transplantation. Results: the overall rate of response to salvage chemotherapy was 13% but that of high dose therapy with stem cell support was 58%. Disease free survival (DFS) in the salvage chemotherapy group was very low; only 2 patients survived in remission without a relapse of disease in long duration. On the contrary the rate of DFS in the transplantation group was 48% at 3 years. At 3 years, the rate of overall survival (OS) was 17% in the group receiving salvage chemotherapy and 31% in the transplantation group. Conclusion: As compared with salvage chemotherapy, treatment with high dose therapy and autologous stem cell transplantation increases disease-free and overall survival in relapsed or refractory patients with non-Hodgkin's lymphoma.

Background : Peritoneal metastasis is one of the maj or types of the stomach cancer recurrence and the role of the adhesion molecules is thought to be very much important in this event. Retinoic acid (RA) has been known to induce the growth inhibition and differentiation of various malignancies, and apoptpsis and the change of expression of adhesion molecules have been reported to be involved in the action of RA. Methods : We studied the adhesion abilities of SNU-1, SNU-5, and SNU-6 cells to the peritoneal endothelial cells as well as the expression of the adhesion molecules (CD44, ICAM-1) in Western blot analysis. And also we studied the expression of apoptosis and the change of expression patterns of the various isoforms of CD44 and the change of the adhsion abilities of the cell line cells after RA treatment. Results: CD44 was expressed in SNU-5 and -16, together with an isoform in SNU-16. ICAM-1 was not expressed in any of the cell line cells tested. After the treatment of RA in the concentration range of $1-5{\times}10^{-5}M$ to three stomach cancer cell lines, growth inhibition, apoptosis and the change of expression of the CD44 were noted. After RA treatment, the expression of CD44H was weakly increased in SNU-1, and was markedly increased in SNU-5. In SNU-16, the expression of CD44H was decreased while that of CD44E were markedly increased. The adhesibility of cells to peritoneal cells was increased in relation with the increase of the CD44H expression, which shows the fact that the adhesibility of tumor cells to peritoneal mesothelial cells is mediated by CD44H recognizing hyaluronic acid. Conclusion : RA induces growth inhibition of stomach cancer cell line cells and increase the adhesiblity of stomach cancer cell line cells to peritoneal mesothelium. It is believed that RA decreases the metastatic ability of stomach cancer cells by upregulating the CD44H expression.

Objectives : Thyroid nodule is a common clinical problem and it is important to distinguish benign from malignant nodule. Although features found on history taking, physical examnation and imaging studies help the diagnosis, fine needle aspiration(FNA) has been accepted as an accurate and reliable diagnostic procedure of thyroid nodule. This study was aimed to assess the values of FNA and needle biopsy in the diagnosis of thyroid nodules. Methods : We reviewed the medical records of the 405 patients who underwent FNA and needle biopsy for the diagnosis of thyroid nodule form September 1993 to July 1996. Results : The 414 fine needle aspiration cytologic specimens were obtained from 405 patients(male : 26, female : 379). 390 cases(94.2%) were adequate for cytologic diagnosis. And the diagnosis showed benign in 357(91.5%), malignancy in 20(5.1%) and suspicious malignancy in 13(3.3%). Among the 357 benign cases, 104 cases were benign cysts, 163 cases were adenomatous goiter and 45 cases were follicular adenoma. 46 patients underwent thyroidectomy after FNA and 21 patients(45.7%) were diagnosed as having carcinoma. The sensitivity and specificity of FNA in diagnosing malignancy were 65% and 82%, respectively, with an accuracy of 74%. Of 46 patients, needle biopsy was done in 41. The sensitivity and specificity of the needle biopsy were 79% and 73%, respectively. And the accuracy was 76%. Hoarseness was developed in one patient after FNA and needle biopsy, and small amount of hemoptysis was developed in another patient after FNA. Conclusion : Although it had been expected that needle biopsy may increase the diagnostic accuracy, our study didn't show the superiority of needle biopsy as compared with FNA. FNA has limitations in suspicious and nondiagnostic results but it is a safe, simple, reliable and cost-effective means of evaluating thyroid nodules. It is the preferred initial diagnostic method in all patients with thyroid nodule.
