Systemic and adjuvant therapy for patients with pancreatic carcinoma

Abstract

BACKGROUND Pancreatic cancer is a highly lethal disease with cc5% of patients surviving 5 years. There is no curative therapy for patients who cannot be surgically resected. Chemotherapy and radiation therapy can provide palliation but have not had a significant impact on 5‐year survival. METHODS Newer approaches for improving the survival of patients with pancreatic cancer integrating chemotherapy, radiation therapy, and surgery are being evaluated. New chemotherapeutic agents (e.g., gemcitabine, camptothecins, taxanes, thymydilate synthase inhibitors, and fluorouracil‐related compounds) are being studied alone and in combination with each other or different agents (e.g., trimetrexate or platinum‐related compounds). RESULTS Increased knowledge about the biology of pancreatic cancer (including high frequency of ras and p53 mutations in neoplastic cells or the expression of a number of growth factor receptors on the cell surface) has lead to preclinical evaluation of novel approaches attempting to specifically target these. These novel approaches include gene therapy, vaccines, and antisense oligonucleotides targeted to genes important for proliferation or survival of pancreatic cancer cells. CONCLUSIONS Continued development of new approaches is needed to improve the treatment and survival of patients with pancreatic cancer. Cancer 1996;78:688‐93.

The effect of targeted magnetic nanopaticles on hepatoma and the expression of bcl-2/bax protein

“…Previous studies revealed that the anti-tumor effect of 5-FU, CDDP and MMC was positively related with apoptosis induction [14][15][16] . Apoptosis is a form of programmed cell death regulated by some gene or other factors [17] .…”
