Cyclophosphamide Hodgkin

LL, a 47-year-old man, was diagnosed with high-risk diffuse large cell B-cell non-Hodgkin s lymphoma (NHL) 12 months ago. LL had a complete response to his initial treatment of six cycles of RCHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). LL is participating in a clinical trial and is randomized to receive a myeloablative autologous HCT TBI days 8 to 5, etoposide day 4, rest day 3, cyclophosphamide day 2, rest day 1, with infusion of autologous PBPC on day 0. 

In addition, combination therapy trials of rituximab with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) in refractory and newly diagnosed patients suggests that rituximab may also have a role in the eradication of residual disease. This combination appears to be a viable treatment option for relapsed low-grade non-Hodgkin lymphoma... 

Cyclophosphamide is nsed both intravenously and orally. It is nsed for chronic lymphatic lenkemia, Hodgkin s disease, Burkitt s lymphoma, multiple myeloma, and cancer of the breast, neck, ovaries, and so on. Synonyms of this drug are endoxan, cyclostin, Cytoxan, cyclophosphane, and others.

Cyclophosphamide (Cytoxan and Endoxan) is used in the treatment of Hodgkin s disease, lymphosarcoma, and other lymphomas. It is employed as a secondary drug in patients with acute leukemia and in combination with doxorubicin in women with breast cancer. A drug combination effective in the treatment of breast cancer is cyclophosphamide, methotrexate, fluorouracil, and prednisone (CMFP). Cyclophosphamide is also an immunosuppressive agent. The toxicity of cyclophosphamide causes alopecia, bone marrow depression, nausea and vomiting, and hemorrhagic cystitis.

Combination chemotherapy is the treatment standard for patients with diffuse non-Hodgkin s lymphoma. The anthracycline-containing regimen CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) has been considered the best treatment in terms of initial therapy. Recently, randomized phase III clinical studies have shown that the combination of CHOP with the anti-CD20 monoclonal antibody rituximab results in improved response rates, disease-free survival, and overall survival compared with CHOP chemotherapy alone. 

Five of thirty-two patients treated with the alternating drug regimen CAMBO-VIP (cyclophosphamide, doxorubicin, methotrexate, bleomycin, vincristine, etoposide, ifosfamide, and prednisolone) for non-Hodgkin s lymphoma developed blisters under the thickened skin of the palms and/or soles, followed by desquamation (28). 

Beau s lines (transverse ridging of the nails) developed after multiple drug therapy for Hodgkin s disease, including cyclophosphamide (30). 

Acute febrile interstitial pneumonitis occurred within less than 48 hours after the second to fourth cycles of chemotherapy (doxorubicin, cyclophosphamide, bleomycin, methotrexate, plus methylprednisolone) in five patients with non-Hodgkin s lymphoma who were receiving prophylactic G-CSF n — 3) or GM-CSF (n = 2) (23). Lymphocytic alveolitis was confirmed in four of these patients and all three patients tested had an increased number of CD8+ T cells. Even though all the patients received high-dose methylprednisolone, two died as a result of diffuse and extensive interstitial pulmonary fibrosis, demonstrated at postmortem. Although both G-CSF and GM-CSF can cause acute pneumonitis in patients with cancers, it is still unknown to what extent hemopoietic growth factors are involved in this complication. 

A 55-year-old man with chronic lymphocytic leukemia and rheumatoid arthritis took methotrexate for 4 years and developed a B cell non-Hodgkin s lymphoma in the shoulder and axillary lymph nodes he had Epstein-Barr viral antigens in the serum. After radiation and chemotherapy had failed, complete remission was achieved with a combination of rituximab and EPOCH (etoposide -I- prednisone -I- vincristine -I-cyclophosphamide + doxorubicin). 

The long-term prognosis for sperm counts after chemotherapy with and without radiation in 71 males treated for non-Hodgkin s lymphoma on the CHOP-Bleomycin combination has been studied (262). Pelvic radiotherapy and cumulative cyclophosphamide dosages of greater than 9.5 g/m are associated independently and in combination with a greater risk of permanent sterility. 

Procarbazine is an alkylating agent that is used in the treatment of Hodgkin s disease in regimens such as MOPP (chlormethine (mechlorethamine), vincristine (Oncovin), procarbazine, and prednisolone) and BEACOPP (bleomycin, etoposide, doxorubicin (Adriamycin), cyclophosphamide, vincristine, procarbazine, and prednisone) (1). It is also used to treat glioblastoma multiforme. 

In 37 patients with HIV-associated non-Hodgkin s lymphoma who were treated with a 96-hour continuous intravenous infusion of cyclophosphamide + doxorubicin + etoposide, severe (grade 3 or 4) mucositis occurred in eight of 12 patients who received concomitant saquinavir (600 mg tds) compared with three of 25 who did not receive saquinavir. Although the authors did not measure saquinavir plasma concentrations, they suggested that this finding may have been explained by inhibition of the metabolism of one or more of the cytotoxic drugs by saquinavir (17). 

AR is a 48-year-old woman who was treated for Hodgkin s disease 15 years ago with ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine). She now presents with breast cancer and her oncologist feels that chemotherapy with FAC (fluorouracil, doxorubicin [Adriamycin], and cyclophosphamide) is the most appropriate regimen. Her previous chemotherapy included a total of 300 mg/m doxorubicin exposure. Which of the following agents may be utilized to reduce risk of cardiotoxicity associated with the anthracycline therapy she is about to receive ... 

In the last 2-5 years, selected monoclonal antibodies have become a routine part of care for certain malignancies. Rituximab, a chimeric monoclonal antibody used against CD 20 positive B-cell non-Hodgkin s lymphoma, is now utilized in combination with the CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone). Trastuzu-mab, a humanized monoclonal antibody, is a weekly maintenance therapy for HER2neu-positive metastatic breast cancer patients.

Ever since MOPP therapy was created and the efficacy confirmed, researchers tried to modify the regimen in an attempt to improve efficacy and decrease toxicity. Some MOPP variations include MVPP (vinblastine substituted for vincristine), CVPP (cyclophosphamide substituted for mechlorethamine), and ChlVPP (chlorambucil substituted for mechlorethamine, and vinblastine substituted for vincristine) were attractive alternatives to MOPP because they offered equal efficacy and differing or less severe toxicities. The various combination chemotherapy regimens appear to produce initial complete response rates in over 80% of the patients treated, and result in a 55% to 65% cure rate for advanced Hodgkin s lymphoma.
