gemcitabine in treating patients with recurrent or metastatic adenoid cystic cancer of the head and neck

Conditions: Head and Neck Cancer

Summary: rationale: drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. purpose: phase ii trial to study the effectiveness of gemcitabine in treating patients who have recurrent or metastatic adenoid cystic cancer of the head and neck.

objectives: * assess the therapeutic activity of gemcitabine, in terms of objective response and duration of response, in patients with recurrent or metastatic adenoid cystic carcinoma of the head and neck. * determine the acute toxicity of this drug in these patients. outline: this is a multicenter study. patients receive gemcitabine iv over 30-60 minutes on days 1 and 8. treatment repeats every 21 days for a maximum of 12 courses in the absence of disease progression or unacceptable toxicity. patients are followed every 12 weeks until disease progression and then every 6 months thereafter. projected accrual: a total of 16-29 patients will be accrued for this study.

Eligibility criteria:
disease characteristics: * histologically confirmed metastatic or recurrent adenoid cystic carcinoma of the head and neck for which no curative options exist * symptomatic and/or progressive disease * at least 1 unidimensionally measurable lesion * at least 20 mm by conventional techniques or * at least 10 mm by spiral ct scan * no bone metastases as only lesion * prior radiotherapy to only target lesion allowed if it has progressed or reappeared after radiotherapy * no cns metastases patient characteristics: age: * 18 and over performance status: * who 0-2 life expectancy: * not specified hematopoietic: * wbc at least 3,500/mm\^3 * absolute neutrophil count at least 1,500/mm\^3 * platelet count at least 100,000/mm\^3 * hemoglobin at least 10 g/dl hepatic: * bilirubin no greater than 1.25 times upper limit of normal (uln) (2.5 times uln if liver metastases present) * ast or alt less than 3 times uln (5 times uln if liver metastases present) renal: * creatinine no greater than 1.7 mg/dl other: * no uncontrolled infection * no concurrent serious systemic disorders that would preclude study * no other prior or concurrent malignancy except: * adequately treated carcinoma in situ of the cervix * basal cell or squamous cell skin cancer * any malignancy that occurred more than 5 years ago with no symptoms or signs of recurrence (except malignant melanoma, hypernephroma, or breast carcinoma) * no psychological, familial, sociological, or geographical condition that would preclude study compliance * not pregnant or nursing * fertile patients must use effective contraception prior concurrent therapy: biologic therapy: * no concurrent immunotherapy chemotherapy: * no prior chemotherapy * no other concurrent chemotherapy endocrine therapy: * no concurrent anti-estrogen therapy * concurrent steroid replacement or steroids as an antiemetic allowed radiotherapy: * see disease characteristics * at least 3 months since prior radiotherapy except for palliative radiotherapy to bone lesions * no concurrent radiotherapy surgery: * not specified other: * at least 1 month since prior investigational agents * no other concurrent experimental medications
