A 59-year-old man presented in January 2003 with generalized lymphadenopathy. An inguinal lymph node biopsy showed mantle cell lymphoma (MCL). After four courses of Rituximab-CHOP therapy were administered, complete response (CR) was achieved. However, in August 2003, he presented with neck lymphadenopathy and was found to have relapsed. Several salvage therapies (ESHAP, Hyper-CVAD/MTX-ara-C) were administered, but CR was not achieved. After two courses of single-agent chemotherapy with CPT-11 (40 mg/m2) were administered on days 1, 2, 3, 8, 9, and 10, CR was achieved. Several studies reveal that the long-term prognosis for MCL with conventional therapy is poor. This report describes CPT-11 therapy for MCL and provides evidence that CPT-11 is another therapeutic option in refractory cases of MCL.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

Treatment Resistent Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
