Abvd

As of 2007, ABVD is widely used as the initial chemotherapy treatment for newly diagnosed Hodgkin's lymphoma. The other chemotherapy regimen that is widely used in this setting is the Stanford V regimen.
Prior to the mid-1960s, advanced-stage Hodgkin disease was treated with single-agent chemotherapy, with fairly dismal long-term survival and cure rates. With advances in the understanding of chemotherapy resistance and the development of combination chemotherapy, Vincent DeVita and George Canellos at the National Cancer Institute (United States) developed the MOPP regimen. This combination of mechlorethamine, vincristine (Oncovin), procarbazine, and prednisone proved capable of curing almost 70% of patients with advanced-stage Hodgkin lymphoma.
While MOPP was remarkably successful in curing advanced Hodgkin lymphoma, its toxicity remained significant. Aside from bone marrow suppression, frequent side effects included nerve injury caused by vincristine and allergic reactions to procarbazine. Long-term effects were also a concern, as patients were often cured and could expect long survival after chemotherapy. Infertility was a major long-term side effect, and even more seriously, the risk of developing treatment-related myelodysplasia or acute leukemia was increased up to 14-fold in patients who received MOPP. These treatment-related hematological malignancies peaked at 5 to 9 years after treatment for Hodgkin's lymphoma, and were associated with a dismally poor prognosis.
Therefore, alternate regimens were tested in an attempt to avoid alkylating agents (such as mechlorethamine), which were thought to be responsible for many of the long-term side effects of MOPP. ABVD was developed as a potentially less toxic and more effective alternative to MOPP; the initial results of ABVD regimen were published at Università degli Studi di Milano,Facoltà di Medicina e Chirurgia, ( anno accademico : 1974/75 ) in : 'Studio comparativo di due schemi di polichemioterapia negli stadi avanzati della Malattia di Hodgkin' , (relatore prof. F. A . ), tesi di laurea di Fossati Vittorio , Matr. 81.606 ,(thesis of a student led by Bonadonna Gianni) and these initial results were also published in 1975 by an Italian group led by Bonadonna. A number of trials then compared MOPP vs. MOPP plus ABVD and compared ABVD to previous and other regimens for Hodgkin lymphoma . A large trial by CALGB suggested that ABVD was superior to MOPP, with a higher rate of overall response, less hematologic toxicity, better relapse-free survival, and better outcomes after relapse in the patients treated with ABVD. Later studies confirmed the superiority of ABVD in terms of effectiveness, and also demonstrated that late side effects, such as treatment-related acute leukemia, were less common with ABVD as compared to MOPP. Taken together, these results led ABVD to the replacement of MOPP with ABVD in the first-line treatment of Hodgkin lymphoma. A number of trials then compared ABVD or ABVD-like or hybrid MOPP/ABVD to BEACOPP and escalated BEACOPP regimens .
One cycle of ABVD chemotherapy is typically given over 4 weeks, with two doses in each cycle (on day 1 and day 15). All four of the chemotherapy drugs are given intravenously. ABVD chemotherapy is usually given in the outpatient setting — that is, it does not require hospitalization.
Typical dosages for one 28-day cycle of ABVD are as follows
The total number of cycles given depends upon the stage of the disease and how well the patient tolerates chemotherapy. Doses may be delayed because of neutropenia, thrombocytopenia, or other side effects.
A PET scan is commonly advised after three cycles of ABVD to assess response to therapy.
In the relative spectrum of cancer chemotherapy, ABVD is not a particularly toxic regimen. Side effects of ABVD can be divided into acute (those occurring while receiving chemotherapy) and delayed (those occurring months to years after completion of chemotherapy). Delayed side effects have assumed particular importance because many patients treated for Hodgkin lymphoma are cured and can expect long lives after completion of chemotherapy.
Supportive care refers to efforts to prevent or treat side effects of ABVD chemotherapy, and to help patients get through the chemotherapy with the least possible discomfort.
