Trial of Radiotherapy and Panitumumab in Salivary Gland Malignancies

2014-07-23 21:12:40 | BioPortfolio

Summary

Standard therapy for high-risk or locally advanced salivary gland malignancies is surgery followed by postoperative radiation therapy. Retrospective studies have shown the superiority of combined modality therapy compared to surgery alone for patients with advanced T or N stage. Despite the addition of postoperative radiation therapy, the five-year survival for locally advanced salivary gland malignancies is poor (less than 60%). In salivary gland malignancies, the epidermal growth factor receptor (EGFR) is expressed in 25-85%; in certain histological types, like salivary duct carcinomas, the expression is higher. EGFR is a promising target of anticancer therapy. In squamous cell carcinoma of the head and neck, a phase III trial utilizing cetuximab added to radiation therapy improved both locoregional control and overall survival compared to radiation alone. Panitumumab is a novel, human, IgG2 EGFR monoclonal antibody that may be better tolerated and more efficacious than cetuximab. Here, the investigators suggest that the addition of panitumumab to standard radiotherapy in locally-advanced salivary gland malignancies will improve recurrence-free survival (RFS).

Salivary Gland Surgery Before Radiation Therapy in Preventing Radiation-Caused Xerostomia in Patients With Head and Neck Cancer

RATIONALE: Moving a salivary gland out of the area that will undergo radiation therapy may protect the gland from side effects of radiation therapy and may prevent xerostomia (dry mouth). ...

Postoperative Concurrent Chemoradiotherapy in Treating Patients With High-Risk Malignant Salivary Gland Tumors

This is a non-randomized, phase II, open label study of postoperative current chemoradiotherapy for high-risk malignant salivary gland tumors of head and neck.The primary purpose of this s...

Concurrent Chemotherapy Based on Genetic Testing in Patients With High-Risk Salivary Gland Tumors

The role of postoperative concurrent chemotherapy (CCT) has not been established for salivary gland tumors (SGTs). This prospective study was conducted to evaluate the feasibility and safe...

Everolimus in Restoring Salivary Gland Function in Participants With Locally Advanced Head and Neck Cancer Treated With Radiation Therapy

This early phase 1 trial studies the use of everolimus in restoring salivary gland function in participants with locally advanced head and neck cancer after concurrent chemoradiation or ra...

Nivolumab and Ipilimumab and Stereotactic Body Radiation Therapy in Treating Patients With Salivary Gland Cancers

This phase I/II trial studies the side effects and how well nivolumab and ipilimumab works when given together with stereotactic body radiation therapy (SBRT) in treating patients with sal...

Disparities in Postoperative Therapy for Salivary Gland Adenoid Cystic Carcinomas.

The patterns of care for salivary gland adenoid cystic carcinomas (ACC) are unknown. We sought to assess predictors of receiving postoperative radiation and/or chemotherapy for patients with nonmetast...

A comparison study of the reporting systems for salivary gland fine needle aspirations: Are they really different?

Recently a new system for reporting salivary gland fine-needle aspiration (FNA) cytology was proposed, the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC). Herein, we evaluated diagno...

An Unusual Salivary Gland Tumor Mimicking Papillary Thyroid Carcinoma: Mammary Analog Secretory Carcinoma.

Thyroid tumors usually present as masses in the thyroid gland. While the majority of these tumors represent neoplasms of thyroid tissues, mainly of follicular epithelial cell differentiation, the diff...

Ancillary testing in salivary gland cytology: A practical guide.

Salivary gland cytology is challenging, and historically the role of ancillary testing has been limited. However, numerous molecular/genetic advances in the understanding of salivary gland neoplasms d...

Pre-treatment metabolic tumor volume predicts tumor metastasis and progression in high-grade salivary gland carcinoma.

High-grade salivary gland carcinoma (SGC) shows a high rate of metastasis and post-treatment recurrence, resulting in poor patient survival. Therefore, we evaluated the utility of pre-treatment F-FDG ...

Medical and Biotech [MESH] Definitions

Calculi occurring in a salivary gland. Most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and in the sublingual and minor salivary glands.

Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).

A fistula between a salivary duct or gland and the cutaneous surface of the oral cavity.

A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575; Holland et al., Cancer Medicine, 3d ed, p1240)

A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)
