Summary

Chemotherapy significantly reduces uterine volume in breast cancer patients, often causing temporary amenorrhea. Uterine volume typically recovers after treatment cessation in premenopausal women.

Area of Science:

  • Oncology
  • Radiology
  • Gynecology

Background:

  • Breast cancer treatment often involves chemotherapy with potential systemic side effects.
  • Uterine volume changes are not typically monitored during such treatments.

Purpose of the Study:

  • To quantify the changes in uterine volume during and after chemotherapy for breast cancer.
  • To correlate uterine volume changes with chemotherapy cycles and menstrual status.

Main Methods:

  • Serial pelvic CT scans were performed on 58 advanced breast cancer patients undergoing FLAC chemotherapy.
  • Uterine dimensions were measured, volumes calculated, and normalized to baseline.
  • Temporal changes were correlated with chemotherapy administration and menstrual status.

Main Results:

  • A consistent loss of uterine volume was observed in 95% of patients during chemotherapy.
  • Mean minimum uterine volume reached 58.3% of baseline, coinciding with amenorrhea.
  • Uterine volume recovery was noted in 12/16 patients post-chemotherapy, with menses returning in four.

Conclusions:

  • Chemotherapy induces significant uterine volume loss in premenopausal women.
  • Uterine volume typically recovers after chemotherapy cessation.
  • These changes should be distinguished from uterine malignancies or tamoxifen effects.
