ABSTRACT
To study the relationship between the expression of the DMBT1 gene in colon carcinoma and its clinical significance. Expression of the DMBT1 gene in colon carcinoma was measured by reverse transcriptase polymerase chain reaction (PT PCR). RT PCR amplification demonstrated that 13 of 36 (36 1%) cases showed an apparent reduction in DMBT1 mRNA in tumor tissues compared with paired normal tissues. Furthermore, the expression of the DMBT1 gene mRNA was reduced in the tumor tissues with lymph nodes metastasis, depth invasion and Dukes`s classification ( P
ABSTRACT
The prognosis of patients with malignant brain tumors has improved only slightly despite the combined use of surgery, radiation therapy, and chemotherapy. Immunotherapy offers some possibilities and hopes as a fourth modality for the treatment of cancers although it is still in the early stages of development. It is possible to classify immunotherapy within four generally accepted modalities : 1) restorative or nonspecific immunotherapy 2) adoptive immunotherapy 3) passive immunotherapy 4) active immunotherapy. The techniques of recombinant DNA, genetic engineering, cell fusion and hybridoma production, and molecular biology will make these therapeutic approaches more successful and as the clinical applications expand the skillful cancertherapist will become increasingly familiar with these treatments and the problems associated with their use.
