Argon Plasma Coagulation (APC) in Palliative Surgery of Head and Neck Malignancies

THE LARYNGOSCOPE, Issue 7 2002
Ulrich Hauser MD
Abstract Objectives Surgical reduction of bulky disease is an important treatment option in patients with incurable head and neck malignancies. In general, conventional tumor ablation is associated with significant hemorrhage, and the resulting tumorous wound surface entails aftercare problems. Argon plasma coagulation (APC) represents a novel technique providing effective hemostasis and wound sealing. Thus, APC features requirements of particular interest in palliative surgery of the head and neck. Study Design Using APC, we performed 18 palliative tumor resections in a series of 8 consecutive patients with recurrent head and neck lesions. Five patients received repeated APC treatment up to five times. Methods APC as non-contact, high-frequency electrosurgery under inert argon plasma atmosphere allows dissection, hemostasis, and desiccation of tumor tissue in a one-step procedure. In consideration of the limited and heterogeneous group of patients, results are interpreted descriptively. Results In every case of palliative surgery, APC caused efficient hemostasis, which helped significantly to reduce both time exposure of the operation and intraoperative loss of blood. Only one APC-unrelated complication occurred (transient rhino-liquorrhea), and none of the patients developed postoperative hemorrhage. Finally, APC produced dry and clean wound surfaces facilitating surgical aftercare. The achieved esthetic and functional improvements strengthened the patient's autonomy and social acceptance. Conclusion APC is highly recommended for palliative surgery of head and neck malignancies. [source]

Preoperative risk assessment for gastrostomy tube placement in head and neck cancer patients

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2001
John M. Schweinfurth MD
Abstract Background The presentation and definitive surgical treatment of head and neck malignancies have varying impact on postoperative recovery and return of swallowing function, which heretofore has not been well defined. Methods We performed a retrospective chart review of 142 patients who underwent extirpative surgery for head and neck cancer. Results Factors significantly associated with the need for long-term postoperative nutritional support (p < .05) included heavy alcohol use, tongue base involvement and surgery, pharyngectomy, composite resection, reconstruction with a myocutaneous flap, radiation therapy, tumor size, and moderately-to-poorly differentiated histology. Heavy alcohol users were at an absolute risk for gastrostomy tube dependence; patients who underwent radiation therapy, flap reconstruction, tongue base resection, and pharyngectomy were at a two to sevenfold increased risk for gastrostomy tube dependence, respectively. Conclusions High-risk patients based on these criteria should receive a feeding gastrostomy at the time of their initial surgical therapy. © 2001 John Wiley & Sons, Inc. Head Neck 23: 376,382, 2001.

The Impact of Surgery in the Management of the Head and Neck Carcinoma Involving the Carotid Artery,

THE LARYNGOSCOPE, Issue 10 2008
Enver Ozer MD
Abstract Objectives/Hypothesis: To demonstrate the feasibility of the carotid artery dissection and/or resection and reanastomosis, and to show its positive impact on survival and disease control rates for the head and neck carcinomas involving the carotid artery. Study Design: Tertiary center (Comprehensive Cancer Center). Case series review. Methods: The data of 90 patients with head and neck malignancies involving the carotid artery were operated for the carotid artery dissection and/or resection, and reanastomosis in the last 10 years were retrospectively reviewed and analyzed. Results: Eighty (89%) of the 90 patients' head and neck malignancies were squamous cell carcinoma. Fifty-two (65%) and 28 (35%) of 80 patients were recurrent and stage IV disease, respectively. There was no stage I to III disease. Carotid artery was dissected and preserved in 64 (71.1%) of the 90 patients. Eighteen (20%) of 90 patients needed carotid artery dissection with resection and reanastomosis. Eight (8.9%) patients were unresectable. Sixty (75%) of 80 patients needed reconstruction with regional or free flaps and grafts. Overall 2- and 5-year estimated survivals were 32.4% and 27.8% for all; 14.3% and 10.7% for recurrent; 64.3% and 57.8% for stage IV previously untreated; and 22.0% and 22.0% for carotid artery resected-reanastomosed patients, respectively. Conclusions: The carotid artery dissection without resection is an achievable goal in majority of patients with the advanced stage head and neck carcinoma involving the carotid artery. Resection and reanastomosis of carotid artery, especially in the previously untreated carotid involved patients, is a feasible surgery and achieves better survival and disease control rates when compared with the unresected or recurrent disease patients.

Dominant Negative p63 Isoform Expression in Head and Neck Squamous Cell Carcinoma,

THE LARYNGOSCOPE, Issue 12 2004
Joseph C. Sniezek MD
Abstract Objectives/Hypothesis: p63, a member of the p53 family of genes, is vital for normal epithelial development and may play a critical role in epithelial tumor formation. Although p63 has been identified in various head and neck malignancies, a detailed analysis of which of the six isoforms of the p63 gene is present in normal mucosa and head and neck malignancies has not yet been performed. The study analyzed p63 isoform expression on the RNA and protein level in normal, diseased, and malignant mucosa of the head and neck to examine the differential expression of p63 isoforms in head and neck tumors versus adjacent nonmalignant tissue and to identify the predominant p63 isoform expressed in head and neck squamous cell carcinoma (HNSCC). Study Design: Three experiments were performed. In experiment 1, p63 expression was analyzed by immunohistochemical analysis in 36 HNSCC specimens and matched normal tissue control specimens harvested from the same patient. Western blot analysis was also performed on matched specimens to confirm the identity of the p63 isoforms that were found. In experiment 2, reverse transcriptase polymerase chain reaction (RT-PCR) analysis was performed on matched normal and tumor specimens to analyze and quantitatively compare p63 isoform expression at the RNA level. In experiment 3, p63 expression was evaluated by immunohistochemical analysis in oral lichen planus, a benign mucosal lesion marked by hyperdifferentiation and apoptosis. Methods: Immunohistochemical analysis, RT-PCR, and Western blot analysis of p63 were performed on HNSCC specimens and matched normal tissue control specimens. p63 expression in oral lichen planus specimens was also examined by immunohistochemical analysis. Results: In experiment 1, analysis of 36 HNSCC specimens from various head and neck subsites showed p63 expression in all tumors and matched normal tissue specimens (36 of 36). Western blot analyses indicated that dominant negative (,N) isoform p63, (,Np63,) is the major isoform expressed at the protein level in tumors and adjacent normal tissue. In experiment 2, RT-PCR analyses of 10 matched specimens confirmed that, although all three ,Np63 isoforms (,Np63,, ,Np63,, and ,Np63,) are expressed in normal and malignant mucosa of the head and neck, ,Np63, is the predominant transcript expressed. In experiment 3, immunohistochemical analysis of p63 in the pro-apoptotic condition of lichen planus indicated that p63 is underexpressed as compared with normal mucosal specimens. Conclusion: Although all three ,Np63 isoforms are present in HNSCC, ,Np63, protein is the predominant isoform expressed in these malignancies. ,Np63, is also overexpressed in tumors compared with matched normal tissue specimens and is underexpressed in the pro-apoptotic condition of lichen planus. These findings suggest that ,Np63, plays an anti-differentiation and anti-apoptotic role in the mucosal epithelium of the head and neck, possibly playing a pivotal role in the formation of HNSCC. Currently, ,Np63, is an attractive target for mechanistic study aimed at therapeutic intervention. [source]
