## **Core Concept**
Hodgkin lymphoma (HL) is a type of lymphoma characterized by the presence of **Reed-Sternberg cells**. The treatment of Hodgkin lymphoma involves a combination of chemotherapy, radiotherapy, and in some cases, targeted therapy. The approach to treatment depends on the stage and specific characteristics of the disease.

## **Why the Correct Answer is Right**
The correct answer involves **ABVD chemotherapy** (Adriamycin, Bleomycin, Vinblastine, and Dacarbazine) which is a common first-line treatment for Hodgkin lymphoma, especially in earlier stages. This regimen has become a standard due to its efficacy and relatively favorable side effect profile compared to older regimens like **MOPP** (Mechlorethamine, Vincristine, Procarbazine, and Prednisone), which had more long-term toxicities.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because, although chemotherapy is a cornerstone of Hodgkin lymphoma treatment, the specifics of the regimen and the inclusion of radiotherapy depend on the stage and risk factors of the disease.
- **Option B:** This option is incorrect as it does not accurately represent the standard treatment approach for Hodgkin lymphoma.
- **Option D:** This option is incorrect because, while **BEACOPP** (Bleomycin, Etoposide, Adriamycin, Cyclophosphamide, Vincristine, Procarbazine, and Prednisone) is an effective regimen, especially in advanced stages, **ABVD** remains a first-line treatment for many patients due to its balance of efficacy and toxicity.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the treatment of Hodgkin lymphoma often involves **risk-adapted therapy**, where the intensity of treatment (e.g., addition of radiotherapy, use of more intensive chemotherapy regimens) is tailored to the patient's specific risk factors and response to initial therapy. Early-stage Hodgkin lymphoma is often treated with **ABVD** followed by **involved-site radiotherapy**, while more advanced disease may require more intensive regimens.

## **Correct Answer:** B. ABVD.
