🐶 Lymphoma in dogs: Are there alternatives to the CHOP protocol?
Lymphomas These are among the most common cancers in dogs. The standard therapy is the so-called CHOP protocol, a combination scheme of Cyclophosphamide, doxorubicin, vincristine and prednisone. While this treatment regimen is effective, it requires weekly visits over several months – a challenge for many pet owners.
A promising alternative could be a combination of Rabacfosdine and Doxorubicin This therapy offers comparable treatment results but requires less frequent clinic visits. In this article, you will learn how this new treatment option works, its advantages and disadvantages, and which dogs it is suitable for.

📖 What does research say about the new therapy?
A recent study with 59 dogs that were attached to multicentric lymphoma The researchers investigated the effectiveness of an alternating protocol with rabacfosadine and doxorubicin in patients who were ill. The results were promising:
✅ 93 of the dogs responded to the therapy.
✅ 6.6 months median progression-free survival (PFS)
✅ 79 of the dogs with % achieved a complete remission., which increased their PFS to 7.2 months
✅ Dogs with B-cell lymphoma had a significantly longer response time (6.6 months) than dogs with T-cell lymphoma (2 months)
These values are comparable to the traditional CHOP protocol, where the median PFS is between 4, 7 and 12.5 months lies.
💉 How does the alternative protocol work?
The dogs received:
🔹 Rabacfosdine (1 mg/kg IV)
🔹 Doxorubicin (30 mg/m² IV for dogs over 15 kg, 25 mg/m² for smaller dogs)
The medications were all 3 weeks alternating administered, in total 6 doses (3x rabacfosadine, 3x doxorubicin).
👉 Fewer hospital visits: Unlike the CHOP protocol, which often requires weekly treatments, dogs only need one treatment here. every three weeks to the clinic.
⚠️ Side effects and risks
Like any chemotherapy, this treatment can also have side effects. The most common are:
- Gastrointestinal problems (Nausea, vomiting, diarrhea)
- Hematological side effects (reduced number of white blood cells, anemia)
- Dermatological reactions (Skin changes caused by rabacfosadione)
- Pulmonary fibrosis (serious but rare lung damage caused by rabacfosadione)
One important point: In the first phase of the study, they developed 15 % of the dogs a lung injury. After prednisone was included in the treatment regimen, this risk decreased to 4 %.
💡 Tip for pet owners: If your dog develops breathing problems during therapy (coughing, rapid breathing, shortness of breath), you should consult a veterinarian immediately.
🏥 For which dogs is this therapy suitable?
Rabacfosadine-doxorubicin therapy could be particularly beneficial for:
🐶 Dogs with B-cell lymphoma, as they respond better to treatment than dogs with T-cell lymphoma.
🐶 Dogs whose owners prefer fewer visits to the vet clinic, because it is administered less frequently than with the CHOP protocol.
🐶 Dogs that respond well to doxorubicin but poorly to vincristine or cyclophosphamide.
⚠️ Not ideal for dogs with pre-existing lung conditions due to the risk of pulmonary fibrosis.
💰 Cost comparison: CHOP vs. Rabacfosadine-Doxorubicin
One important point is the price. Rabacfosadine can be significantly more expensive than the CHOP protocol., especially for large dogs, as several vials are needed.
| Therapy | Treatment duration | Costs | Advantages |
|---|---|---|---|
| CHOP protocol | 4-6 months | Average costs | Standard treatment, proven |
| Rabacfosdine-Doxorubicin | 3-4 months | Higher | Fewer hospital visits, comparable effectiveness |
💡 Conclusion: For owners willing to accept higher costs, the new therapy could be a good alternative.
📌 Conclusion: Is the new therapy a real alternative?
✅ Comparable efficacy to the CHOP protocol
✅ Less frequent hospital visits
✅ Good results for B-cell lymphoma
⚠️ Higher costs than CHOP
⚠️ Risk of pulmonary fibrosis (reducible by prednisone)
This therapy could be a useful option for dog owners who have a less time-consuming treatment wish. However, who who is afraid of the costs or has a dog with lung problems, should seek good advice.
