Overview

Primary resection of tumor is one of the main prognostic factors in rhabdomyosarcoma. However, surgical resection of the rhabdomyosarcoma is often difficult or impossible because the tumor is usually embedded deep within the tissue, leaving it difficult to reach. Surgical tumor resection must contain complete tumor removal with performing safe margin resection. In case of narrow margins, several biopsies are needed to identify residual disease. If surgical excision could not be performed, 12 weeks chemotherapy is recommended. Assessment of lymph nodes are essential as well such as assessment of axillary and femoral lymph nodes in rhabdomyosarcoma of extremities.

Surgery

Primary resection of tumor is one of the main prognostic factors in rhabdomyosarcoma.^[1]^[2]
Based on tumor‘s location, surgical resection may be different.
Findings of surgical resection is essential for risk stratification.
Surgical tumor resection must contain complete tumor removal with performing safe margin resection.
- Although recommended safety margin is 2 cm, it is impossible to perform in children because of tissue limitation.^[3]
- Several biopsies are needed in case of narrow margins to identify residual disease.
If surgical excision could not be performed, 12 weeks chemotherapy is recommended.
Lymph nodes need to be assessed for further evaluation.
- In extremities of rhabdomyosarcoma, axillary and femoral lymph nodes should be assessed.

**Treatment for rhabdomyosarcoma**
Location	Symptoms
Head and neck^[4]	Due to cosmetic concerns, wide local excision is not capable. Cervical lymph node assessment is not essential.
Extremities^[5]^[6]^[7]	Tumor resection should be performed with maintaining extremities function. Sentinal lymph node biopsy is required. In perineal and anal rhabdomyosarcoma, ilioinguinal lymphadenectomy is required. In cases with positive margin, re-excision must be done for evaluation.
Paratesticular region^[8]^[9]	Radical inguinal orchiectomy and spermatic cord resection are required. Routine ipsilateral nerve-sparing retroperitoneal lymph node dissection (RPLND) is required in boys aged > 10 years old. In boys aged < 10 years old, Only excision of present enlarged lymph nodes on radiography is required.
Genitourinary tumors^[10]^[11]^[12]	It is recommended to perform chemotherapy first to make tumors resectable. Cystectomy is performed before chemotherapy only in tumor from dome of bladder.
