Patient case: 54-year-old female with Breast cancer. Genetic variant: PTEN Loss. Other conditions: Congestive Heart Failure.

Clinical trial: SWOG-9342 Chemotherapy in Treating Women Enrolled in the SWOG-8897 Clinical Trial

Summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
  PURPOSE: This clinical trial is studying the effect of chemotherapy on heart function in treating women who have breast cancer with negative axillary lymph nodes and who are undergoing treatment on the SWOG-8897 clinical trial.

Detailed description: OBJECTIVES:
  -  Compare the frequency of subclinical congestive heart failure by measuring resting MUGA at 5-8 and 10-11 years after randomization in women receiving adjuvant chemotherapy with cyclophosphamide, methotrexate, and fluorouracil or cyclophosphamide, doxorubicin, and fluorouracil on protocol SWOG-8897.
  -  Estimate the frequency of late cardiac effects (congestive heart failure, cardiac ischemic events, and clinical symptoms) in these patients treated with these regimens.
  -  Monitor prospectively the incidence of annual cardiac events between the fifth and tenth year after randomization of these patients to these regimens.
  OUTLINE: This is a multicenter study.
  The treating physician completes patient cardiovascular and routine history and physical examination questionnaires at baseline and yearly. Patients undergo resting MUGA scans at 5-8 and 10-11 years after registration on protocol SWOG-8897. The first scan must be performed within 3 months prior to enrollment or within 1 month after registration on the current study, and the second scan must be done in the tenth year of follow-up and within 3 months prior to enrollment or 1 month from the anniversary of registration on the current study.
  PROJECTED ACCRUAL: A total of 420 patients will be accrued for this study. After initial accrual is completed, approximately 50 additional patients will be accrued at 10 years.
