Patient case: 67-year-old male with esophageal cancer; genetic feature: EGFR

Clinical trial: Flavopiridol and Paclitaxel in Treating Patients With Locally Advanced or Metastatic Esophageal Cancer That Has Not Responded to Previous Paclitaxel

Summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells.
  PURPOSE: Phase II trial to study the effectiveness of combining flavopiridol and paclitaxel in treating patients who have locally advanced or metastatic esophageal cancer that has not responded to previous paclitaxel therapy.

Detailed description: OBJECTIVES:
  -  Determine the response rate in patients with paclitaxel-refractory locally advanced or metastatic esophageal cancer treated with sequential paclitaxel and flavopiridol.
  -  Determine the toxicity of this regimen in these patients.
  -  Assess the quality of life of patients treated with this regimen.
  -  Obtain pharmacokinetic information about this regimen.
  OUTLINE: This is a multicenter study.
  Patients receive paclitaxel IV over 3 hours on day 1 and flavopiridol IV continuously over 24 hours on day 2 weekly for 3 weeks. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.
  Quality of life is assessed at baseline, after courses 1 and 2, and then every 2 courses thereafter.
  PROJECTED ACCRUAL: A total of 12-37 patients will be accrued for this study within 6-18 months.

Eligibility: DISEASE CHARACTERISTICS:
  -  Histologically confirmed squamous cell carcinoma or adenocarcinoma of the esophagus or carcinoma of the gastroesophageal (GE) junction
  -  If tumor extends below the GE junction into the proximal stomach, 50% of the tumor must involve the esophagus or GE junction
  -  No gastric cancers with only a minor involvement of the GE junction or distal esophagus
  -  Metastatic or locally advanced disease that is considered surgically unresectable
  -  Must have failed a prior chemotherapy regimen that included paclitaxel for metastatic disease OR
  -  Failed prior combination taxane-based chemotherapy and radiotherapy for locally advanced disease
  -  Must have documented evidence of the following:
  -  Disease progression while on taxane-based neoadjuvant or adjuvant therapy OR
  -  Recurrent disease within 6 months of therapy
  -  Measurable disease
  -  Accurately measured in at least 1 dimension
  -  At least 20 mm by conventional techniques OR
  -  At least 10 mm by spiral CT scan
  -  The following are considered nonmeasurable:
  -  Bone lesions
  -  Leptomeningeal disease
  -  Ascites
