Summary
Advancements in chemotherapy offer cures for many malignant lymphomas, even in advanced stages. Combining non-cross-resistant drug regimens, like MOPP-ABVD, improves cure rates and reduces resistance in Hodgkin
Area of Science:
- Oncology
- Hematology
- Pharmacology
Background:
- Malignant lymphomas present a significant challenge in oncology, with drug resistance being a primary obstacle to complete remission.
- Chemotherapy has evolved, offering potential cures for a substantial number of patients, including those with advanced disease.
Purpose of the Study:
- To review current chemotherapy strategies for malignant lymphomas, focusing on improving cure rates and overcoming drug resistance.
- To evaluate the efficacy of alternating non-cross-resistant drug regimens and salvage therapies.
Main Methods:
- Review of clinical data on chemotherapy regimens for Hodgkin's disease and non-Hodgkin's lymphomas (NHL).
- Analysis of combination chemotherapy protocols, including MOPP-ABVD and intensive polydrug regimens.
- Examination of salvage regimens and novel treatments for relapsed or resistant lymphomas.
Main Results:
- The MOPP-ABVD program shows a 15-20% increase in cure rates for stage IV Hodgkin's disease compared to MOPP alone.
- Intensive polydrug regimens can now cure at least 50% of patients with diffuse large-cell NHL.
- Salvage regimens may cure 20-25% of MOPP-resistant Hodgkin's disease patients, with promising results for relapsed NHL using agents like cisplatin.
Conclusions:
- Alternating non-cross-resistant chemotherapy regimens enhance cure rates in malignant lymphomas.
- Novel drug combinations and salvage therapies, including autologous bone marrow transplantation, show promise for resistant lymphomas.
- Strategies to mitigate treatment-induced toxicities like leukemia and sterility are being developed.
