title: A case report of ultrasound-guided interstitial brachytherapy for abdominal wall metastases of ovarian cancer.
abstract: OBJECTIVE
  To report the treatment effect of interstitial brachytherapy for abdominal wall metastases of ovarian cancer.
  
  
  METHODS
  The patient is a 44-year-old female with a diagnosis of stage IA ovarian cancer. After surgery and two cycles of chemotherapy with paclitaxel and carboplatin, the patient noticed dull pain in the lower abdomen and found a mass located in the subcutaneous tissue, below the operative incision. A diagnostic biopsy showed abdominal wall metastases. After external radiotherapy with a dose of 39.6 Gy in 22 fractions, the residual tumor was treated with interstitial brachytherapy under ultrasound guidance. The brachytherapy dose was 18 Gy in 6 fractions of 3 Gy each.
  
  
  RESULTS
  After 3 weeks of brachytherapy, the tumor had disappeared completely. Interstitial brachytherapy was feasible.
  
  
  CONCLUSIONS
  Interstitial brachytherapy may be a proposed treatment strategy for inoperable superficial metastases, especially for low radiosensitivity cancer.
