With regard to using a histone dicetylase inhibitor for lymphoma treatment, a contact at the NCI is Robin Frye, RN, at (302) 402-5958, and is available at many cancer centers in the United States. A contact for treating thyroid cancer with histone diacetylase inhibitors has been reported to be Deborah Draper, RN, BSN, at (301) 435-8525.

Despite dramatic advances in the treatment of several human malignancies including Hodgkin s lymphomas and leukemias, dmg resistance remains a pressing issue in cancer chemotherapy. Acquired or induced dmg resistance afflicts practically all classes of cancer agents. It usually is manifested clinically... 

Ricin [9009-86-3], a phytotoxin found in the seeds of the castor oil plant Acinus communis, conjugated to murine monoclonal antibody (Immunogen Corp.), has been approved by the U.S. Food and Dmg Administration (FDA) for the treatment of patients with B-ceU leukemia and lymphoma (59). 

Poly(ethylene glycol) (PEG) molecules attached to adenosine deaminase (ADA) have been used in patients exhibiting symptoms of the severe combined immunodeficiency syndrome (SCID) caused by ADA deficiency. The modified enzyme has a plasma half-life of weeks as compared to the unmodified enzyme (minutes) (248). PEG-L-asparaginase has induced remissions in patients with non-Hodgkin s lymphoma (248). However, one disadvantage of PEG-enzyme treatment is its expense, ie, a year s treatment costs about 60,000 (248). 

Nitrogen mustard is clinically used for the treatment of lymphomas and some forms of lung cancer. The major indication for mechlorethamine is Hodgkin s disease as a part of the MOPP regimen (mechlorethamine + vincristine (oncovin) + procarbazine + prednisone). The usual dose consists of 6 mg/m2 on days 1 and 8. This drug has pronounced hematological toxicity (myelo-suppression). 

Lomustine (2-chlorethyl-3 cyclohexyl-1 -nutrosourea, CCNU, Fig 3) is a nitrosourea for oral application. It is used for the treatment of Hodgkin s lymphomas, brain tumors and bronchial carcinomas at a dose of 3.5 mg/kg (130 mg/m2) repeated in 6-8 weeks intervals. 

Bendamustine is a useful antineoplastic drug for the treatment of non-Hodgkin s lymphomas, multiple myeloma and as a partner drug in the combination therapy of some solid tumors. The cross-resistance with other alkylating drugs is not complete. Myelosuppression and lymphocytopenia is its main dose-limiting toxicity. 

MTX is part of curative therapeutic schedules for acute lymphoblastic leukemias (ALL), Burkitt s lymphoma, and choriocarcinoma. It was also used in adjuvant therapy of breast cancer. High dose MTX with leucovorin rescue can induce about 30% remissions in patients with metastatic osteogenic sarcoma. MTX is one of the few antineoplastic drugs that can be safely administered intrathecally for the treatment of meningeal metastases and leukemic infiltrations (routine prophylaxis in ALL). In addition, MTX can be used as an immunosuppressive agent for the treatment of severe rheumatoid arthritis and psoriasis. 

Cancer treatment is a multimodality treatment, i.e., surgery is combined with radiotherapy and antineoplastic chemotherapy. The latter treatment mode is used mainly for cancers which have disseminated. Different forms of cancer differ in their sensitivity to chemotherapy with antineoplastic agents. The most responsive include lymphomas, leukemias, choriocarcinoma and testicular carcinoma, while solid tumors such as colorectal, pancreatic and squamous cell bronchial carcinomas generally show a poor response. The clinical use of antineoplastic agents is characterized by the following principles. 

A large and rapidly growing number of clinical trials (phase I and phase II) evaluating the potential of DNA vaccines to treat and prevent a variety of human diseases are currently being performed ( http // clinicaltrials.gov) however, there is yet no licensed DNA vaccine product available for use in humans. The clinical trials include the treatment of various types of cancers (e.g., melanoma, breast, renal, lymphoma, prostate, and pancreas) and also the prevention and therapy of infectious diseases (e.g., HIV/ABDS, malaria, Hepatitis B vims, Influenza vims, and Dengue vims). So far, no principally adverse effects have been reported from these trials. The main challenge for the development of DNA vaccines for use in humans is to improve the rather weak potency. DNA vaccines are already commercially available for veterinary medicine for prevention of West Nile Vims infections in horses and Infectious Hematopoetic Necrosis Vims in Salmon. 

Chemotherapy of cancer started in the early 1940s when nitrogen mustard was administered to patients with lymphoma. Since then, numerous agents have been developed for the treatment of different cancers. 

Vinblastine is another vesicant vinca alkaloid that causes myelo-suppression and less neurotoxicity than vincristine. The pharmacokinetics of vinblastine are best described by a three-compartment model, with an a half-life of 25 minutes, a 3 half-life of 53 minutes, and a terminal half-life of 19 to 25 hours.12 Vinblastine has shown activity in the treatment of bladder, breast, and kidney cancer, as well as some lymphomas. The doses of vinblastine tend to be higher on a milligram per meter squared basis than vincristine. Nausea and vomiting are minimal with vinblastine. Other side effects include mild alopecia, rash, photosensitivity, and stomatitis. 

Etoposide causes multiple DNA double-strand breaks by inhibiting topoisomerase II. The pharmacokinetics of etoposide are described by a two-compartment model, with an a half-life of 0.5 to 1 hour and a (5 half-life of 3.4 to 8.3 hours. Approximately 30% of the dose is excreted unchanged by the kidney.16 Etoposide has shown activity in the treatment of several types of lymphoma, testicular and lung cancer, retinoblastoma, and carcinoma of unknown primary. The intravenous preparation has limited stability, so final concentrations should be 0.4 mg/mL. Intravenous administration needs to be slow to prevent hypotension. Oral bioavailability is approximately 50%, so oral dosages are approximate two times those of intravenous doses however, relatively low oral daily dosages are used for 1 to 2 weeks. Side effects include mucositis, myelosuppression, alopecia, phlebitis, hypersensitivity reactions, and secondary leukemias. 

Teniposide, a topoisomerase II inhibitor, is administered as an infusion over 30 to 60 minutes to prevent hypotension. The pharmacokinetics are described by a three-compartment model, with an a half-life of 0.75 hours, a (5 half-life of 4 hours, and a terminal half-life of 20 hours. Considerable variability in clearance of teniposide in children has been reported.17 Teniposide has shown activity in the treatment of acute lymphocytic leukemia, neuroblastoma, and non-Hodgkin s lymphoma. Side effects include myelosuppression, nausea, vomiting, mucositis, and venous irritation. Hypersensitivity reactions may be life-threatening.
