Template:WH Template:WS Drugs used are vincristine, actinomycin D(dactinomycin), adriamycin(doxorubicin). Stages I and II Initial therapy is with vincristine and actinomycin D(dactinomycin) in case of those with favorable histology. In recurrent cases as well as those with unfavorable histology, adriamycin(doxorubicin) is added to the regimen.
Stages III, IV, V Therapy is initiated with vincristine, actinomycin D(dactinomycin) and adriamycin(doxorubicin)
Etoposide, carboplatin and cyclophosphamide are added if necessary. Mesna(sodium 2-mercaptoethane sulfonate) is given with cyclophosphamide.
The current NWTS recommendations are as follows [1]
For tumors with favorable histology:
Stage I and II tumors - 18 weeks of therapy with Dactinomycin + Vincristine
Stage III and IV tumors - 24 weeks of therapy with Dactinomycin + Vincristine + Doxorubicin; as well as radiotherapy to tumor bed and involved sites
For tumors with unfavorable histology: Stage I - 18 weeks of therapy with Dactinomycin + Vincristine
Stages II -IV - 24 weeks of therapy with Dactinomycin + Vincristine + Doxorubicin + Cyclophosphamide + Etoposide; as well as radiotherapy to tumor bed and involved sites
The SIOP recommendations are as follows [1]
Stage I tumors of low grade - no chemotherapy necessary
Stage I tumors of intermediate grade or showing anaplasia - 18 weeks of therapy with Dactinomycin + Vincristine
Stage II without lymph node involvement - 28 weeks of therapy with Dactinomycin + Vincristine + Epirubicin
Stage II with lymph node involvement and Stage III - 28 weeks of therapy with Dactinomycin + Vincristine + Epirubicin; as well as radiotherapy to tumor bed
High grade tumors - 34 weeks of therapy with Epirubicin + Ifosfamide + Etoposide + Carboplatin; as well as radiotherapy
Stage IV (metastatic) - as per the appropriate local stage of the tumor; as well as treatment of metastases by surgery or radiotherapy
Recurrent tumors
ifosfamide, etoposide and carboplatin may be used.
