Overview
Treatment for rhabdomyosarcoma may consists of chemotherapy, radiation therapy and surgery. Chemotherapy may be given as neoadjuvant chemotherapy or adjuvant chemotherapy. Radiation therapy may be used as local therapy.
Medical Therapy
- Rhabdomyosarcoma treatment include combination of surgery, radiotherapy, and chemotherapy.[1]
- Rhabdomyosarcoma treatments depends on staging classification and risk stratification. For more information click here.
- Rhabdomyosarcoma chemotherapy depends on patient's risk groups.
- Vincristine, actinomycin-d,and cyclophosphamide are the fundamental chemotherapy standard based on Children's Oncology Group.
- In low-risk patients, cyclophasphamide dosage and chemotherapy duration can be decreased in order to decline chemotherapy toxicity.
- Ifosfamide, vincristine, and actinomycin-d are the fundamental chemotherapy standard base on European Soft tissue Sarcoma Group.[2][3]
- Ifosfamide is used instead of cyclophosphamide to decrease gonadal toxicity amount.
- Patients's response to chemotherapy is classified to following groups:[2][4]
| Patients response | Tumor volume reduction |
|---|---|
| Complete response | No measurable tumor volume as compared to initial one |
| Good response | Volume reduction of > 2/3 tumor as compared to initial one |
| Poor response | Volume reduction of > 1/3 and < 2/3 as compared to initial one |
| Objective response | Volume reduction of > 1/3 as compared to initial one |
| Progressive disease | Volume increase of > 1/3 or new lesion development |
Radiotherapy
- Radiation therapy may be used as local therapy. External beam radiation is used in some cases of rhabdomyosarcoma.
The treatment for rhabdomyosarcoma varies depending upon the location of tumor:[5]
| Location | Symptoms |
|---|---|
| Head and neck | Wide local excision; chemotherapy +/- radiation therapy |
| Bone around the eye | Biopsy; chemotherapy + radiation therapy |
| Extremities | Wide local excision; resection of nearby lymph nodes; amputation for extensive tumors |
| Abdomen or pelvis | Neoadjvant therapy with chemotherapy and radiotherapy; wide local excision |
| Paratesticular region | Removal of testes and spermatic cord; ipsilateral retroperitoneal lymphnode resection |
