Primary ovarian rhabdomyosarcoma: A diagnostic dilemma in an uncommon tumor

Journal of cancer research and therapeutics · Oct 2025 · case report

CyclophosphamideActinomycin-dVincristineovarian rhabdomyosarcoma

This case report describes a 17-year-old girl with a very rare ovarian rhabdomyosarcoma. The tumor was diagnosed by imaging, pathology, and immunohistochemistry, and it came back within 3 months after surgery. The authors report that she then received VAC chemotherapy (vincristine, actinomycin D, and cyclophosphamide), and they emphasize the need for earlier diagnosis and more standardized treatment approaches.

Studied with: vincristine, actinomycin D, cyclophosphamide.

Key findings
  • Imaging showed a large solid-cystic pelvic mass.
  • Histopathology and immunohistochemical markers (desmin, myogenin, WT1) confirmed ovarian rhabdomyosarcoma.
  • Recurrence occurred within 3 months after surgical resection.
  • VAC chemotherapy was given after early relapse.
Limitations: Single-patient case report.; No control group.; No quantitative treatment outcome data reported.; Cannot determine effectiveness of VAC from this report alone.; Focus is diagnostic and descriptive rather than evaluative..

Describes a rare ovarian cancer case and subsequent chemotherapy, but does not evaluate a compound's anticancer effect in a comparative way.

Primary ovarian rhabdomyosarcoma in children

Pediatric surgery international · May 2008 · case reports

CyclophosphamideVincristineDoxorubicinovarian rhabdomyosarcomaalveolar rhabdomyosarcomaembryonal rhabdomyosarcoma

This report describes two children with very rare primary ovarian rhabdomyosarcoma. After complete surgical removal, both received chemotherapy with vincristine, doxorubicin, and cyclophosphamide and had a good response. Both patients were alive 8 and 9 months after surgery.

Key findings
  • Two pediatric cases of primary ovarian rhabdomyosarcoma were described.
  • Both patients underwent complete resection of the primary tumor.
  • Both received vincristine, doxorubicin, and cyclophosphamide chemotherapy.
  • The abstract reports a good response to therapy and survival at 8 and 9 months post-operatively.
Limitations: Case report with only 2 patients.; No control group.; Short follow-up.; Cannot separate the effect of surgery from chemotherapy.; No dosing details reported..

Describes management of a rare ovarian cancer in children, including chemotherapy, but does not isolate the effect of any single compound.

Mixed mesodermal sarcoma of the ovary. Treatment with combination radiation therapy and chemotherapy

Cancer · Oct 1983 · retrospective case series

VincristineCyclophosphamidemixed mesodermal sarcoma of the ovary

This retrospective report reviews 20 patients with ovarian mixed mesodermal sarcoma and focuses on 12 patients treated after surgery with combined radiation and VAC chemotherapy (vincristine, dactinomycin, cyclophosphamide). Four of the 12 had complete tumor control (one alive without disease beyond 5 years, three died of unrelated causes without disease at autopsy) and one other had an 18-month disease-free interval. The authors state that combination radiation plus VAC appears effective compared to prior reports but note myelosuppression and gastrointestinal and neurologic toxicities, and they recommend treatment modifications.

Reported effects: total patients reviewed - count 20 · patients treated post-operatively with combination therapy - count 12 · +4 more

Studied with: radiation therapy.

Key findings
  • Twenty patients with mixed mesodermal sarcoma of the ovary were reviewed.
  • This report focuses on 12 patients treated post-operatively with combination radiation therapy and chemotherapy with vincristine, dactinomycin, and cyclophosphamide (VAC).
  • There were 4 patients achieving complete tumor control, including one who is alive without disease beyond 5 years and 3 who died of unrelated causes without disease at autopsy.
  • One other patient had a significant disease-free interval of 18 months.
  • Compared to previous reports, combination radiation and VAC chemotherapy appears effective in this disease.
  • Myelosuppression and gastrointestinal and neurologic toxicities were observed and treatment modifications have been recommended.
Limitations: Small sample size (focused on 12 treated patients).; Retrospective case series without a control group.; Single-center experience.; Limited detail on dosing, toxicity grading, and follow-up duration for all patients..

Where at least one study reported a positive result, shown with the full picture, not just the wins. Positive results are more likely to be published, and most of these are early lab or animal studies that may not translate to people. This reports what studies found, not what works.
