NCT07334626

Brief Summary

Breast cancer survivors receiving endocrine (hormonal) therapy (aromatase inhibitors) are at high risk for cancer treatment-induced bone loss and osteoporosis due to estrogen depletion.

Outcome Measures

Primary Outcomes (1)

  • Bone mineral density (BMD) measurement

    Change in bone mineral density (BMD) at the lumbar spine and total hip (g/cm²) from baseline to 12 weeks. BMD will be measured using dual-energy X-ray absorptiometry (DEXA), which is the standard technique for assessing BMD at the lumbar spine and proximal femur. The BMD and T-score of the femoral neck and lumbar vertebrae will be determined using a Hologic Discovery W series DEXA scanner.

    Base line and after 12 weeks

Secondary Outcomes (1)

  • Functional Assessment of Cancer Therapy - Breast (FACT-B) questionnaire.

    Base line and after 12 weeks

Study Arms (2)

Study group

EXPERIMENTAL
Other: Pilates ExercisesDrug: Calcium and Vitamin D Supplementation

Control group

ACTIVE COMPARATOR
Drug: Calcium and Vitamin D Supplementation

Interventions

The Pilates program will consist of mat-based exercises with optional use of light equipment such as resistance bands and small weights. Each session will last 60 minutes and will be performed three times per week over a total duration of 12 weeks. The program will follow a structured progression with systematic increases in exercise difficulty, load, and repetitions based on individual tolerance. The intervention will focus on enhancing core control, spinal extension and posture, lower-limb weight-bearing activities, and balance. Sessions will be initially supervised by a trained physiotherapist with expertise in oncology rehabilitation.

Study group

Participants will receive daily oral calcium supplementation at a total dose of 1,200 mg/day, combined with vitamin D (total daily vitamin D dose: 200 IU), administered throughout the study period as part of standard osteoporosis management for breast cancer survivors receiving hormonal therapy.

Eligibility Criteria

Age40 Years - 60 Years
Sexfemale(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Female breast cancer survivors aged 40-60 years.
  • Histologically confirmed stage I-III breast cancer.
  • Currently receiving hormonal therapy (aromatase inhibitors) for at least 3 months.
  • At risk of osteoporosis or with low bone mineral density (BMD) defined by T-score ≤ -1.0 at lumbar spine or hip.
  • Medically cleared for exercise, specifically low-to-moderate intensity Pilates.
  • Able to attend supervised exercise sessions three times per week for 12 weeks.
  • Willing and able to provide written informed consent.

You may not qualify if:

  • Metastatic (stage IV) or recurrent breast cancer.
  • History of osteoporotic fractures in the past 12 months.
  • Severe cardiovascular, respiratory, or musculoskeletal conditions that contraindicate exercise.
  • Uncontrolled hypertension, diabetes, or thyroid disorders.
  • Current use of corticosteroids.
  • Active bone metabolic disease other than osteoporosis (e.g., Paget's disease, osteomalacia).
  • Severe cognitive impairment or psychiatric illness preventing adherence to exercise or supplementation.
  • Known allergy or intolerance to calcium or vitamin D supplementation.
  • Participation in another clinical trial with structured exercise or bone-targeted intervention within the last 3 months.
