Primary Outcome Measures:
  • Number of successes per number of evaluable samples [ Time Frame: up to 4 years after registration ]
    Success is defined as obtaining at least 10 analyzable metaphases.

  • Number of abnormalities per number of successes [ Time Frame: up to 4 years after registration ]
    Abnormality is defined as at lease one clonal chromosomal abnormality.

  • Correlation of tumor response to treatment with the type and number of abnormalities [ Time Frame: up to 4 years after registration ]
    Abnormality is defined as at lease one clonal chromosomal abnormality.

  • Correlation of time from diagnosis to development of metastatic disease with the type and number of abnormalities [ Time Frame: up to 4 years after registration ]
    Abnormality is defined as at lease one clonal chromosomal abnormality.

  • Correlation of time from first diagnosis of metastatic disease until death with the type and number of abnormalities [ Time Frame: up to 4 years after registration ]
    Abnormality is defined as at lease one clonal chromosomal abnormality.

Primary Completion Date: December 2002 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

  • Determine if cytogenetic abnormalities can predict clinical outcome, in terms of response to treatment and survival, in patients with metastatic renal cell carcinoma registered to the nephrectomy arm (arm I) of SWOG-8949.
  • Correlate cytogenetic abnormalities and DNA content analysis (DNA index and S-phase fraction) with clinical outcome.

OUTLINE: This is a partially prospective, partially retrospective, multicenter, companion study.

Paraffin-embedded tumor tissue specimens from patients enrolled in SWOG-8949 are evaluated by cytogenetic analysis (e.g., presence of trisomy and loss of Y chromosome) and flow cytometric analysis (e.g., presence of nondiploid cells and presence of abnormal proliferation index).

PROJECTED ACCRUAL: A total of 80 patients will be accrued for this study.
