Trial Description

Summary

TRIAL STATUS: Active

This randomized phase II/III trial studies radiation therapy with or without chemotherapy to see how well it works in treating patients with high-risk malignant salivary gland tumors that have been removed by surgery. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether radiation therapy is more effective when given together with chemotherapy or alone after surgery in treating salivary gland tumors.

Further Study Information

PRIMARY OBJECTIVES:

I. Determine the feasibility of conducting a cooperative group prospective clinical trial in patients with resected malignant salivary gland tumors. (Phase II)

II. Acquire preliminary efficacy data comparing postoperative radiotherapy alone to concurrent chemotherapy and radiation using weekly cisplatin. (Phase II)

III. Compare overall survival rates among patients receiving cisplatin and radiation to those receiving radiation alone. (Phase III)

SECONDARY OBJECTIVES:

I. Compare the acute toxicities of these 2 adjuvant treatments.

II. Compare late treatment-related adverse events in patients receiving postoperative radiation to those receiving concurrent chemoradiation.

III. Compare progression-free survival rates among patients receiving cisplatin and radiation to those receiving radiation alone in both the cohort of patients with pathologically high-risk disease (high-grade adenocarcinoma, high-grade mucoepidermoid carcinoma, salivary duct carcinoma), and the patient cohort with pathologically intermediate-risk disease (all other eligible diagnoses).

IV. Investigate quality of life and patient-reported outcomes in patients enrolled in the study.

V. Identify the histopathology and tumor marker expression from patients enrolled on this trial and assemble a tissue bank for future correlative studies.

VI. Establish an NRG Oncology baseline database for salivary gland malignancies to serve as a resource for future exploration of innovative and/or targeted approaches for this disease.

OUTLINE: Patients are stratified according to histology (intermediate-grade adenocarcinoma or intermediate-grade mucoepidermoid carcinoma vs high-grade adenocarcinoma, high-grade mucoepidermoid carcinoma or salivary duct carcinoma vs high-grade acinic cell carcinoma or high-grade [> 30% solid component] adenoid cystic carcinoma) and nodal status (N0 vs N1-3). Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients undergo 3-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiation therapy (IMRT) 5 days a week for 6-6.5 weeks. Patients also receive cisplatin intravenously (IV) over 60 minutes on days 1, 8, 15, 22, 29, 36, and 43 during radiotherapy.

Arm II: Patients undergo 3D-CRT or IMRT as in Arm I.

After completion of study treatment, patients are followed up at 3, 6, 9, 12, 18, and 24 months, every 6 months for 2 years, and then annually thereafter.

Eligibility Criteria

Inclusion Criteria:

Pathologically proven diagnosis of a malignant major salivary gland tumor or malignant minor salivary gland tumor of the head and neck of the following histologic subtypes:

Intermediate-grade adenocarcinoma or intermediate-grade mucoepidermoid carcinoma

High-grade adenocarcinoma or high-grade mucoepidermoid carcinoma or salivary duct carcinoma

High-grade acinic cell carcinoma or high-grade (> 30% solid component) adenoid cystic carcinoma

Patients with diagnoses such as "undifferentiated or poorly differentiated carcinoma", "carcinoma-ex pleomorphic adenoma", "carcinoma not otherwise specified (NOS)" and others should be considered for this trial
