Purpose
Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have progressive, refractory, or recurrent stage II or stage III testicular cancer or stage II or stage III ovarian cancer following cisplatin-based chemotherapy

- Response rate defined as either a complete or partial response using RECIST criteria [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]Response rate (CR+PR) and exact 95% confidence interval based on the binomial distribution for the response rate will be computed.
- Grade 1 or higher toxicities assessed using CTC)version 2 [ Time Frame: Up to 2 years ] [ Designated as safety issue: Yes ]Toxicities will be tabulated.
- Duration of response [ Time Frame: From first response (CR or PR) to the date of disease progression or death, assessed up to 2 years ] [ Designated as safety issue: No ]The Kaplan-Meier product-limit method will be used.
- Disease-free survival [ Time Frame: From the date of initiation of treatment to date of progression or death due to any cause, whichever occurs first, assessed up to 2 years ] [ Designated as safety issue: No ]The Kaplan-Meier product-limit method will be used.
- Overall survival [ Time Frame: From date of initiation of treatment to date of death due to any cause, assessed up to 2 years ] [ Designated as safety issue: No ]The Kaplan-Meier product-limit method will be used.
- Proportion of patients with mutations in the c-KIT gene [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]The 95% confidence interval will be estimated.

Experimental: Treatment (imatinib mesylate and surgical resection)
Patients receive oral imatinib mesylate once daily. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients who achieve a partial response or stable disease with normalization of human chorionic gonadotropin may undergo surgical resection of residual lesions at each tumor status assessment. If residual viable germ cell tumor is present in the resected specimen, patients may resume imatinib mesylate. If no viable germ cell tumor is present in the resected specimen, then no further therapy is administered.

Detailed Description:
OBJECTIVES:
I. Determine the activity of imatinib mesylate in patients with progressive, refractory, or recurrent pure testicular seminoma or ovarian germ cell dysgerminoma after cisplatin-based chemotherapy.
II. Determine the toxicity of this drug in this patient population. III. Determine KIT expression and identify mutations in the c-kit gene in patients treated with this drug.
OUTLINE: This is a multicenter study.
Patients receive oral imatinib mesylate once daily. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients who achieve a partial response or stable disease with normalization of human chorionic gonadotropin may undergo surgical resection of residual lesions at each tumor status assessment. If residual viable germ cell tumor is present in the resected specimen, patients may resume imatinib mesylate. If no viable germ cell tumor is present in the resected specimen, then no further therapy is administered.
Patients are followed every 3 months for 1 year and then every 6 months for 1 year.
PROJECTED ACCRUAL: A total of 32 patients will be accrued for this study within 32-38 months.

Inclusion Criteria:
Histologically confirmed pure testicular seminoma or ovarian germ cell dysgerminoma
- Histologic documentation of metastatic/recurrent disease not required
- Alpha-fetoprotein level must be normal, unless abnormal level is explained by other conditions and approved by the study chair
- Clinical stage II or III
Progressive, refractory, or recurrent disease, meeting at least 1 of the following criteria:
- Measurable progressive disease
- Biopsy-proven residual disease
- Persistently elevated or rising B-human chorionic gonadotropin (HCG) titers, defined as at least 2 values above the upper limit of normal (ULN)
Cisplatin-refractory disease without option of potentially curative therapy, meeting 1 of the following criteria:
- Failed high-dose chemotherapy with peripheral blood stem cell transplantation (PBSCT) or autologous bone marrow transplantation (AuBMT)
- Ineligible for or refused PBSCT or AuBMT
- Unlikely to achieve long-term benefit from PBSCT or AuBMT
Current evidence of metastatic disease
Unidimensionally measurable target lesions
- At least 20 mm by conventional techniques (e.g., physical examination for clinically palpable lymph nodes and superficial skin lesions or chest x-ray for clearly defined lung lesions surrounded by aerated lung)
- At least 10 mm by spiral CT scan or MRI
- If measurable disease is confined to a solitary lesion, then its neoplastic nature must be confirmed by histology
- Ultrasound may not be used to measure tumor lesions that are not easily accessible clinically
Non-measurable/non-target lesions, with HCG at least ULN, including the following:
- Bone lesions
- Pleural or pericardial effusions
