Aggressive Local Therapy for Limited Bone-Only Metastasis to Improve Progression-Free Survival in Breast Cancer Patients

This study is ongoing, but not recruiting participants.
Sponsor:
Information provided by (Responsible Party):
M.D. Anderson Cancer Center
ClinicalTrials.gov Identifier:
NCT00929214
First received: June 25, 2009
Last updated: May 8, 2017
Last verified: May 2017
  Purpose
The goal of this clinical research study is to find out if adding local therapy (surgery and/or radiation) to standard therapy (chemotherapy or endocrine therapy) in the treatment of patients with metastatic breast cancer can help to control the disease for a longer period of time than standard therapy alone.

Condition Intervention Phase
Breast Cancer Drug: Standard Therapy Procedure: Local Therapy Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Aggressive Local Therapy for Limited Bone-Only Metastasis to Improve Progression-Free Survival in Breast Cancer Patients

Primary Outcome Measures:
  • Number of Patients with Progression-Free Survival (PFS) [ Time Frame: Study assessment at 9 Months ]
    Progression-free survival defined as 1) development of distant soft tissue or visceral metastasis at any time, 2) progression of bone lesion(s) that received planned local therapy (as defined by the imaging response criteria described by Hamaoka et al., and 3) development of new bone lesions after patient receives planned local therapy. Development of additional bone metastasis prior to receiving planned local therapy not be considered as event if the total number of bone metastasis is 3 or less. An event has occurred if additional bone metastasis develops and total number of bone metastasis is 4 or more.


Estimated Enrollment: 75
Actual Study Start Date: June 2009
Estimated Study Completion Date: June 2019
Estimated Primary Completion Date: June 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Standard Therapy + Local Therapy
Systemic Standard Therapy (chemotherapy and/or endocrine therapy) + Local Therapy (surgery and/or radiation)
Drug: Standard Therapy

Chemotherapy and/or Endocrine Therapy:

For 3 - 9 months, all patients will receive systemic chemotherapy agents appropriate for the tumor characteristics and patient's prior treatment history, and may also be placed on endocrine therapy as determined by the treating medical oncologist.

Other Names:
  • Chemotherapy
  • Endocrine Therapy
  • Systemic Chemotherapy
Procedure: Local Therapy

Surgery and/or Radiation Therapy

With no more than 3 bone metastases, local treatments including high-dose radiation therapy and/or surgery will be given. Radiation therapy involves daily treatments during weekdays that may last 5 to 7 weeks in a row. Each daily treatment may last 30 - 40 minutes. Surgery, including recovery, may last 4 to 6 weeks.

Other Names:
  • Radiation Therapy
  • RT
  • XRT
  • Surgery

  Eligibility

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Breast cancer with metastasis to skeletal sites only
  2. 1 to 3 bone metastatic sites (metastatic lesions in the same bone that are within 3 cm of each other are considered as one site)
  3. KPS greater than or equals to 70
  4. Absolute neutrophil count of > 1500 per microliter and platelet count > 100,000 per microliter; AST and alkaline phosphatase < = 2.5 X normal limits, bilirubin < = 1.5 x normal limits, calculated creatinine clearance > 50 ml/min using Cockcroft-Gault formula: CrCl male = (140-age) x (wt. in kg)/(Serum Cr x 72); CrCl female = 0.85 x (CrCl male)
  5. Patients may or may not have started bis-phosphonates.
  6. Patients who have received prior chemotherapy for their original breast cancer treatment are still eligible.
  7. Previous use of systemic therapy for bone metastasis is allowable as long as the systemic therapy use fits within the treatment plan as described in Proposed Treatment/Study Plan. (If the patient received less than 3 - 9 months of systemic therapy previously, the use of additional systemic therapy may be necessary to fit within the treatment plan)
  8. Treating physician assesses tumor to be sufficiently distant from sensitive structures to be able to achieve greater than or equal to 66 Gy. (i.e., spinal cord tolerance respected in vertebral body metastasis.
  9. Patients with immanent risk of fracture(s) may receive local therapy prior to systemic therapy. Otherwise systemic therapy should be given first as outlined in abstract treatment study plan sections 1 and 2.

Exclusion Criteria:

  1. Distant metastasis to organs (local recurrence and regional lymph node recurrence are not considered as distant metastasis) other than bone
  2. Prior radiation to site(s) of distant metastasis of bone
  3. History of scleroderma and systemic lupus erythematosus which increases the risk of toxicity from radiation treatment
  4. Second primary malignancy (skin cancer other than melanoma allowed) that is disease free for less than 3 years
  5. Premenopausal and postmenopausal (amenorrheic for less than 12 months) women with either a positive or no pregnancy test (serum or urine) at baseline within 7 days study enrollment. Postmenopausal women who are amenorrheic for more than 12 months do not require pregnancy test.
  6. Women with child-bearing potential not using a reliable an appropriate contraceptive method.
  7. Patients with child-bearing potential will agree to use contraception while on study and for 30 days from the date of the last therapy on protocol.
  8. If the patient requires surgery of the bone metastasis, clinically serious comorbidities that render patient not medically fit for surgery (e.g. congestive heart failure, symptomatic coronary artery disease, cardiac arrhythmias and chronic lung disease not well controlled with medication; myocardial infarction within 12 months of enrollment)
  9. Central nervous system disorders or psychiatric disability judged by the investigator to be clinically significant to preclude informed consent or interfere with complying with protocol treatments.
