RESUMO

PURPOSE: The Patient Concern Inventory© (PCI) is a clinical tool of self-reported patient concerns to be used by the clinician to structure the patient-oncologist visit. It was developed in the United Kingdom to address the issues of quality of life (QOL) in head and neck cancer (HNC) patients. The purpose of the study reported here was to determine the prevalence of PCI© items, the associations between PCI© items and QOL, and to explore the importance of oral/dental issues in the patient's well-being. METHODS: The PCI© and the University of Washington (UW-QOLv4) instruments were self-administered by an HNC population in a cross-sectional study. Following an a priori sample size estimate, consecutive HNC patients attending at the University of Florida's Oral Medicine and the ENT Clinics had the study described, eligibility assessed, and if eligible, were invited to participate in the study. Participants completed the PCI© and UW-QOL. PCI© issues prevalence was determined, and for those with a ≥10% prevalence: 1) Fisher's exact test was used to test for statistical differences between treatments, and 2) multivariable regression was used to test each of the prevalent PCI© issues across four QOL measures, health in the last 7 days, overall QOL in the last 7 days, and the physical and social domain scores. RESULTS: Twenty of 45 PCI© issues had a prevalence ≥10%. Of the 15 prevalent items statistically associated with a QOL measure, four issues are the clinical responsibility of the dental profession: 1) chewing/eating, 2) dental health/teeth, 3) mouth opening, and 4) salivation. An additional four (eight total, 50%) are of clinical concern for dental clinicians: 5) pain in head/neck, 6) swallowing, 7) speech/voice/being understood, and 8) taste. CONCLUSIONS: Dental concerns represent almost half of all PCI© concerns observed in 10% or more of the sample patients. Prosthodontists should support our maxillofacial prosthodontics specialists in joining other oral oncologists and advocate for comprehensive, integrated dental support for HNC patients by assuring dental involvement/inclusion with the multidisciplinary oncology team and a research agenda to established best patient-centered outcomes.

RESUMO

OBJECTIVES: There is controversy about the prognosis of Hurthle cell carcinoma of the thyroid. The purpose of this project is to report the outcome of a well-defined group of patients treated at a single institution in the modern era. METHODS: Sixteen patients met the following inclusion criteria: Treatment with curative intent at our institution between January 1, 1997, and December 31, 2010. Primary treatment with total thyroidectomy with or without neck dissection. Age >18 years at the time of thyroidectomy. Confirmation by a pathologist of the diagnosis of a primary Hurthle cell carcinoma of the thyroid based on ≥75% Hurthle cells with extension through the tumor capsule. No areas of poorly differentiated (insular) or undifferentiated (anaplastic) carcinoma. Stage T1-3, NX-1b, M0. All patients received radioiodine immediately after thyroidectomy (remnant ablation, n=14) or as adjuvant for a recurrence (n=2). External-beam radiotherapy to the neck as adjuvant therapy after thyroidectomy was used in 2 patients and after resection of a neck recurrence in 1 patient. RESULTS: Five-year actuarial rates with a median 6 years of follow up on surviving patients were as follows:Overall and cancer-specific survival: 92% (1 death from Hurthle cell carcinoma). Relapse-free survival (no visible tumor and unstimulated thyroglobulin ≤1.0): 65%. CONCLUSIONS: Our experience suggests that the outcome of Hurthle cell carcinoma of the thyroid is favorable in adults with stage T1-3 NX-1b M0 disease who are managed with total thyroidectomy, radioiodine, and-in selected cases-external-beam radiotherapy. We do not have the ability to compare our results to other management strategies.

RESUMO

The objective of this study is to determine if radiotherapy (RT) alone to the cervical lymphatics is a suitable alternative to elective neck dissection (END) in patients who undergo parotidectomy and postoperative RT for squamous cell carcinoma metastatic to the parotid area lymph nodes (PALN). We retrospectively reviewed the medical records of 107 patients consecutively treated from November 1969 to March 2012 for cutaneous squamous cell carcinoma metastatic to the PALN with a clinically node-negative neck. Primary therapy consisted of parotidectomy in all cases. We compared regional (cervical) control in two subgroups: 42 patients treated with END and RT and 65 patients treated with elective neck irradiation (ENI) alone. The median time of follow-up was 5.5 years (range 0.3-30 years) for all patients and 11 years for living patients (range 1.8-26 years). There was 1 neck recurrence in each subgroup: END and RT, 1/42 (2 %); and ENI alone, 1/65 (1.5 %). No patient experienced a complication related to neck RT. ENI to a dose of approximately 50-60 Gy is a suitable alternative to END and postoperative RT in patients with squamous cell carcinoma metastatic to the PALN.

RESUMO

This study is aimed at updating our institution's experience with definitive radiotherapy (RT) for squamous cell carcinoma of the tonsil. We reviewed 531 patients treated between 1983 and 2012 with definitive RT for squamous cell carcinoma of the tonsil. Of these, 179 patients were treated with either induction (n = 19) or concomitant (n = 160) chemotherapy. Planned neck dissection was performed on 217 patients: unilaterally in 199 and bilaterally in 18 patients. Median follow-up was 5.2 years for all patients (range 0.1-31.6 years) and 8.2 years for living patients (range 1.9-31.6 years). The 5-year local control rates by T stage were as follows: T1, 94 %; T2, 87 %; T3 79 %; T4, 70 %; and overall, 83 %. Multivariate analysis revealed that local control was significantly influenced by T stage and neck dissection. The 5-year cause-specific survival rates by overall stage were as follows: I, 94 %; II, 88 %; III, 87 %; IVA, 75 %; IVB, 52 %; and overall, 78 %. Multivariate analysis revealed that cause-specific survival was significantly influenced by T stage, N stage, overall stage, fractionation, neck dissection, sex, and ethnicity. Of 77 patients treated with ipsilateral fields only, contralateral neck failure occurred in 1 %. The rate of severe complications was 12 %. Definitive RT for patients with tonsillar squamous cell carcinoma provides control rates equivalent to other modalities with a comparatively low incidence of late complications. Patients with anterior tonsillar pillar or tonsillar fossa primaries that are well lateralized with no base of tongue or soft palate extension may be treated with ipsilateral fields.

RESUMO

PURPOSE: This is a retrospective analysis of the 50-year University of Florida experience treating adenoid cystic carcinoma of the lacrimal gland with radiation therapy. MATERIALS AND METHODS: Between 1965 and 2015, 8 patients with adenoid cystic carcinoma of the lacrimal gland received radiation therapy with curative intent. Four patients received postoperative radiation therapy and 4 received definitive radiation therapy alone. The median follow-up was 3.3 years (range, 0.3 to 11.2 years). RESULTS: All 4 patients who received postoperative radiation therapy received 74.4 Gy. The 4 patients who received radiation therapy alone received a median dose of 72.3 Gy (range, 70.0 to 74.4 Gy). The overall survival rates at 5 and 10 years were 25% and 13%, respectively. The cause-specific survival rates at 5 and 10 years were 29% and 14%, respectively. The local control and freedom from metastases rates at 5 and 10 years were both 43%. Local recurrences occurred in 50% of patients, and distant metastatic disease occurred in 38% of patients. No patients experienced acute complications of treatment that warranted a treatment break. Two patients experienced bone exposure as late complications of treatment. CONCLUSIONS: The results of this study illustrate the propensity for adenoid cystic carcinoma of the lacrimal gland to recur both locally and with distant metastases despite aggressive local treatment measures. This study also demonstrates the relatively poor outcomes for individuals with this type of tumor.

RESUMO

The purpose of this study is to report our institutional experience using radiotherapy in the treatment of ameloblastoma and ameloblastic carcinoma. Three patients with ameloblastoma and 3 patients with ameloblastic carcinoma were treated with radiotherapy alone (2 patients) or surgery and postoperative radiotherapy (4 patients) at the University of Florida between 1973 and 2007. Follow-up ranged from 4.0 to 13.1 years with a median of 7.8 years. Radiotherapy complications were scored using the Common Terminology Criteria for Adverse Events, version 4.0. Local control was achieved in 4 of the 6 patients. One patient treated with RT alone for an unresectable ameloblastoma developed a local recurrence and metastases in both the cervical lymph nodes and lungs, but had excellent response to dual BRAF/MEK inhibition with dabrafenib and trametinib. Another patient treated with surgery and postoperative radiotherapy for an ameloblastic carcinoma recurred locally without metastasis, but was not salvaged. No significant treatment-related complications were observed. For patients with local recurrence or inadequate margins after surgery, adjuvant radiotherapy provides the potential for disease control. In the setting of metastatic disease, targeted therapies may provide an additional opportunity for salvage.

RESUMO

BACKGROUND: Many guidelines recommend random directed biopsies of the nasopharynx, contralateral tonsil, and hypopharynx to evaluate an unknown primary squamous cell carcinoma of the head and neck. There are no published data documenting the need for these recommendations. The purpose of our study was to report the rate of positive blind biopsies in this setting. METHODS: We recorded the rate of positive random directed biopsies performed as part of the workup for 156 patients treated with radiotherapy between 1985 and 2014 for an unknown primary squamous cell carcinoma presenting with the main location of adenopathy in nodal stations 2, 3, 4, or 5. RESULTS: Rate of positive result by subsite: nasopharynx and pyriform sinus = 0%; tonsillectomy: ipsilateral = 39%, bilateral = 6%; and base of tongue = 18%. CONCLUSION: With modern imaging, random directed biopsies of the nasopharynx and hypopharynx are unnecessary in the workup of unknown primary squamous cell carcinoma of the head and neck.

RESUMO

We evaluated the treatment of squamous cell carcinoma (SCC) of the nasal vestibule. Eighty-six patients were treated with radiotherapy (RT) and 13 patients received surgery and RT. The mean follow-up was: 9.7 years (range 4 months-35.9 years). The 5- and 10-year outcomes were: local control (LC), 88 and 82 %; local-regional control (LRC), 78 and 73 %; freedom from distant metastases (FFDM), 96 and 96 %; cause-specific survival (CSS), 91 and 86 %; and overall survival, 75 and 51 %. The 5- and 10-year LC rates for patients treated with RT were 94 and 89 % overall. A multivariate analysis was performed. Tumor size predicted LC, LRC, OS, and CSS. Overall stage predicted LRC. RT cures most patients with T1-T2 and favorable T4 SCCs with acceptable toxicity. RT and surgery result in improved likelihood of cure for patients with advanced T4 lesions.

RESUMO

The purpose of this study is to update our institution's experience with ipsilateral radiation therapy (RT) for squamous cell carcinoma of the tonsillar area. Outcome study of 76 patients treated between 1984 and 2012 with ipsilateral RT for squamous cell carcinoma of the tonsil. Patients had either cT1 (n = 41, 54 %) or cT2 (n = 35, 46 %) primaries and cN0 (n = 27, 36 %), cN1 (n = 15, 20 %), cN2a (n = 8, 11 %), or cN2b (n = 26, 34 %) nodal disease. Of these, 32 (42 %) patients underwent a planned neck dissection and 21 (28 %) patients received concomitant chemotherapy. Median follow-up for all patients was 7.1 years (range 0.1-27.2) and 7.8 years (range 2.1-27.2 years) for living patients. The 2- and 5-year control and survival rates were as follows: local control, 98.6 and 96.9 %; local-regional control 95.8 and 92.6 %; cause-specific survival 95.9 and 93.1 %; and overall survival, 92.1 and 83.8 %. One patient failed in the contralateral, non-radiated neck 3 years after primary treatment. Univariate analysis revealed that overall survival was significantly influenced by whether the patient had a primary tumor in the anterior tonsillar pillar versus the tonsillar fossa with the latter performing better. The incidence of severe late complications was 16 %. Ipsilateral RT for patients with squamous cell carcinoma of the anterior tonsillar pillar or tonsillar fossa with no base of tongue or soft palate extension is an efficacious treatment that provides excellent control rates with a relatively low incidence of late complications.

RESUMO

The objective of this study is to report the long-term outcomes of primary radiotherapy (RT) for patients with T1-T2 squamous cell carcinomas (SCC) of the pyriform sinus. Between November 1964 and March 2008, 135 patients with T1-T2 pyriform sinus SCC were treated with primary RT at the University of Florida. Adjuvant chemotherapy was employed in 21 patients (16 %) and 62 patients (46 %) underwent a planned neck dissection. Median follow-up was 3.5 years (range 0.2-24.7 years); median follow-up on living patients was 8.3 years (range 3.8-24.0 years). The 5-year outcomes were as follows: local control, 85 %; regional control, 81 %; local-regional control, 71 %; distant metastasis-free survival, 76 %; cause-specific survival, 62 %; and overall survival, 38 %. The 5-year local control rate was 88 % for T1 cancers and 84 % for those with T2 SCCs (p = 0.5429). Sixteen patients (12 %) experienced severe late complications. Primary RT results in a high probability of cure with a relatively modest risk of severe late complications for patients with T1-T2 SCCs of the pyriform sinus.

RESUMO

OBJECTIVES: To report the results of a standardized program using positron emission tomography (PET)-computed tomography (CT) approximately 12 weeks after primary radiotherapy to determine the need for a planned neck dissection in patients with radiographic N2 squamous cell carcinoma (SCC) of the oropharynx. METHODS: Fifty consecutive patients with T1-4 and hemineck radiographic stage N2A-B SCC of the oropharynx for whom the only indication for planned neck dissection was a positive PET-CT performed ∼12 weeks after completing primary treatment with radiotherapy. RESULTS: Results of PET-CT to identify residual neck disease were as follows: sensitivity and positive predictive value, 0%; specificity, 89%; negative predictive value, 91%; potential neck recurrence from using this 12-week PET-CT program, 2%. The time between negative PET-CT and detection of neck recurrence was 0.5, 0.6, 1.2, and 2.0 years. The rate of successful (>1 year) salvage of neck recurrence was 25% (1/4). CONCLUSIONS: PET-CT approximately 12 weeks after radiotherapy for oropharyngeal cancer is an excellent way to identify patients who do not need neck dissection. Approximately half of neck recurrences present over 1 year after negative PET-CT and the chance of successful salvage is low.

RESUMO

PURPOSE/OBJECTIVES: Treatment outcomes were analyzed for patients who received radiotherapy for squamous cell carcinoma of the retromolar trigone at a single institution. MATERIALS/METHODS: We reviewed the medical records of 110 patients treated with radiotherapy alone (n=36) or radiotherapy combined with surgical resection of the primary tumor (n=74) between June 1966 and October 2013. The median follow-up was 4.5years for all patients and 11.8years for living patients (range, 1.3-23.5years). RESULTS: The 5-year local-regional control rates after definitive radiotherapy versus surgery and radiotherapy for stages I-III were 52% and 89% and for stage IV they were 46% and 58%, respectively. The 5-year cause-specific survival rates after definitive radiotherapy compared with surgery and radiotherapy for stages I-III were 57% and 82% and for stage IV they were 45% and 43%, respectively. Multivariate analyses revealed that the likelihood of cure was better with surgery and radiotherapy compared with radiotherapy alone (p=0.041). CONCLUSION: Patients treated with surgery and radiotherapy had a better chance of cure than those treated with radiotherapy alone. Complications of treatment were common in both groups but more common in patients who underwent surgery.

RESUMO

OBJECTIVES: To evaluate the efficacy of postoperative radiotherapy for oral cavity squamous cell carcinoma (OCSCC) by comparing outcomes of high-risk subgroups. STUDY DESIGN: Retrospective review. METHODS: Outcome study of 139 patients with OCSCC treated with gross total resection and postoperative radiotherapy ± chemotherapy and at least one high-risk pathologic finding: positive margin (52%), close (0.1-5 mm) margin (27%), or extracapsular nodal extension (ECE; 45%). RESULTS: Median follow-up was 2.3 years. Local-regional control (LRC), freedom from distant metastases, cause-specific survival, and overall survival (OS) rates at 5 years were 64%, 85%, 51%, and 36%, respectively. Five-year LRC for negative (>5 mm), close (0.1-5 mm), and positive (carcinoma in situ or tumor at ink) margins were 73%, 83%, and 63%, respectively (P = not significant). Five-year neck control was 100% for node-negative patients, 88% for node-positive patients with no ECE, and 86% for node-positive patients with ECE (P = not significant). The combination of close/positive margin and ECE resulted in worse 5-year LRC (37% vs. 70%, P < 0.001), progression-free survival (26% vs. 60%, P < 0.001), and OS (13 vs. 43%, P < 0.001) compared with a single high-risk indication. CONCLUSIONS: Local-regional control was the predominant mode of treatment failure. Outcome in our series was not statistically different based on margin status or nodal ECE. This finding is indirect evidence of the efficacy of adjuvant radiotherapy in this setting.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the long-term effectiveness and complications of radiotherapy (RT) in the treatment of patients with mucosal melanomas of the head and neck. MATERIALS AND METHODS: The medical records of 21 patients treated with definitive or postoperative (RT) between 1974 and 2011 at the University of Florida Department of Radiation Oncology in Gainesville, FL, and the University of Florida Proton Therapy Institute in Jacksonville, FL, were retrospectively reviewed under an Institutional Review Board-approved protocol. Primary sites included nasal cavity, oropharynx, and paranasal sinuses. Sixteen patients (76%) received surgery and postoperative RT and 5 patients (24%) received RT alone. Seventeen patients received photon RT alone, whereas 4 patients received combined photon-based and proton-based RT. Median follow-up for all patients was 1.05 years (range, 0.36 to 12.97 y); median follow-up for survivors was 2.2 years (range 0.9 to 13.0 y). RESULTS: The 5-year outcomes were: local control, 79%; regional control, 85%; local-regional control, 65%; distant metastasis-free survival, 20%; cause-specific survival, 22%; and overall survival, 22%. Three patients (14%) experienced severe complications including bilateral blindness and skin necrosis. CONCLUSIONS: Definitive or postoperative RT for mucosal melanoma of the head and neck yields fairly good local-regional control of disease. The prognosis for patients treated with definitive RT is less promising than for those who receive surgery and postoperative RT.

RESUMO

OBJECTIVES: Esthesioneuroblastoma is an uncommon cancer of the nasal cavity. We describe the outcomes for 26 patients treated with curative intent with photon radiotherapy (RT) at the University of Florida. METHODS: Between May 1972 and June 2007, 26 patients received RT for previously untreated esthesioneuroblastoma of the nasal cavity. Sixteen patients were males and 10 were females with a median age of 55 years (range, 3 to 82 y). The modified Kadish stage distribution was: B, 7 patients; C, 17 patients; and D, 2 patients. Treatment modalities included the following: definitive RT, 5 patients; preoperative RT, 2 patients; and postoperative RT after resection, 19 patients. Elective neck irradiation (ENI) was performed in 17 (71%) of 24 N0 patients. RESULTS: Rates of local control, cause-specific survival, and absolute overall survival at 5 years were 79%, 72%, and 69%, respectively. Overall survival among patients treated with definitive RT was 20% at 5 years, compared with 81% among those who underwent surgery and adjuvant RT (P=0.01). One (6%) of 17 patients who received ENI developed a recurrence in the neck and was successfully salvaged. Ultimate neck control was 100% at 5 years for patients who received ENI versus 69% among those not receiving ENI (P=0.0173). CONCLUSIONS: Resection combined with adjuvant RT is more effective than surgery or RT alone in the treatment of esthesioneuroblastoma. ENI reduces the risk of regional relapse in patients with Kadish stage B and C cancers.

RESUMO

BACKGROUND: Paragangliomas of the head and neck are rare, slow-growing, generally benign tumors of neuroendocrine cells associated with the peripheral nervous system that commonly involve the carotid body, jugular bulb, vagal ganglia, and temporal bone. Treatment options include surgery, radiotherapy (RT), stereotactic radiosurgery (SRS), and observation. This article briefly reviews our 45-year institutional experience treating this neoplasm with RT. METHODS: From January 1968 through March 2011, 131 patients with 156 benign paragangliomas of the temporal bone, carotid body, jugular bulb, or glomus vagale were treated with RT at a median dose of 45 Gy in 25 fractions. The mean and median follow-up times were 11.5 years and 8.7 years, respectively. RESULTS: Five tumors (3.2%) recurred locally after RT, all within 10 years of treatment. The overall local control rates at 5 and 10 years were 99% and 96%, respectively. The cause-specific survival rates at 5 and 10 years were 98% and 97%, respectively. The distant-metastasis free survival rates at 5 and 10 years were 99% and 99%, respectively. The overall survival rates at 5 and 10 years were 91% and 72%, respectively. There were no severe complications. CONCLUSION: RT for benign head and neck paragangliomas is a safe and efficacious treatment associated with minimal morbidity. Surgery is reserved for patients in good health whose risk of associated morbidity is low. SRS may be suitable for patients with skull base tumors <3 cm where RT is logistically unsuitable. Observation is a reasonable option for asymptomatic patients with a limited life expectancy.

RESUMO

Polymorphous low-grade adenocarcinomas are rare tumors that can arise from many areas of the head and neck. We reviewed the pertinent literature pertaining to the incidence, diagnostic evaluation, and treatment strategies for this malignancy. Histopathologic diagnosis always involves careful analysis of tissue and especially characteristic immunohistochemical staining patterns. Common differential diagnoses include adenoid cystic carcinoma, pleomorphic adenoma, and other benign or malignant salivary gland neoplasms. Although the ideal treatment is debated, surgical resection at times combined with adjuvant radiation therapy is preferred by many physicians. Further research will be needed to delineate optimal management.

RESUMO

PURPOSE: To evaluate the long-term effectiveness of radiotherapy (RT) in the treatment of sinonasal undifferentiated carcinoma (SNUC). MATERIALS AND METHODS: The medical records of 23 patients treated with definitive or postoperative RT between 1992 and 2010 at the University of Florida were retrospectively reviewed. Fifteen patients (65%) received primary surgery and postoperative RT. Radiation doses ranged from 59.0 to 74.8 Gy (median, 70.2 Gy). The median follow-up time for all patients was 3.0 years (range, 0.9-19.9), and for living patients was 7.7 years (range, 2.5-19.9). RESULTS: The actuarial 5-year survival outcomes were as follows: progression-free survival, 42%; cause-specific survival, 43%; and overall survival, 32%. Actuarial 5-year disease control rates were as follows: local control (infield or marginal), 74%; local-regional control (excluding leptomeningeal spread), 58%, regional control 78%, freedom from leptomeningeal recurrence, 72%, and distant metastasis-free survival, 73%. Five of the 8 (62.5%) patients treated with definitive RT died with disease, and 6 of the 15 patients (40%) treated with primary surgery and postoperative RT died with disease. Three patients (13%) experienced severe complications including unilateral eye removal, osteoradionecrosis of the maxilla requiring hyperbaric oxygen and surgery, and brain necrosis. One patient died due to an infected bone graft and brain abscess. CONCLUSIONS: A multimodal approach is best when treating SNUC patients. The prognosis for patients treated with definitive RT ± chemotherapy is less promising than for those who receive surgery and postoperative RT ± chemotherapy. Severe complications occur in about 17% of patients due to the high dose of RT alone or combined with surgery required for acceptable disease control.

RESUMO

PURPOSE: To assess the efficacy of postoperative radiotherapy (RT) in the treatment of cutaneous melanoma. MATERIALS: Between August 1981 and December 2009, 82 patients were treated with surgery and postoperative RT for cutaneous melanoma. Patients were thought to be high risk for local-regional recurrence after surgery alone because of the presence of one or more risk factors including recurrence after prior surgery, positive lymph nodes, extracapsular extension, incomplete regional node dissection, microscopically positive margins, gross residual disease, and in-transit metastases. The primary site was located in the head and neck in 64 patients and elsewhere in the remainder. Forty-two patients (47%) were treated with hypofractionated RT and the remainder with conventional fractionation. Median age was 62 years (range, 21 to >89 years). Median follow-up overall and for survivors was 3.0 years (range, 0.1 to 17.4 years) and 6.4 years (1.6 to 17.4 years), respectively. RESULTS: The 5-year outcomes were: in-field local-regional control 82%; local-regional control, 76%; distant metastasis-free survival, 48%; cause-specific survival, 56%; and overall survival, 43%. In-field local-regional control at 5 years was 87% after hypofractionated RT and 78% after conventionally fractionated RT. CONCLUSIONS: Postoperative adjuvant RT likely reduces the risk of local-regional recurrence after surgery for patients with high risk cutaneous melanoma. Hypofractionated RT is as effective as conventional fractionation and is logistically advantageous, particularly for patients with a relatively poor prognosis. The risk of RT complications is low.

RESUMO

PURPOSE: To determine whether patients with clinically node negative (cNo) high grade salivary gland carcinomas benefit from an elective neck dissection prior to postoperative radiotherapy (RT). MATERIAL/METHODS: Between October 1964 and October 2009, 59 previously untreated patients with cNo high-grade salivary gland carcinomas (squamous cell carcinomas were excluded) were treated with curative intent using elective neck dissection (END; n=41), or elective neck irradiation (ENI; n=18) at the University of Florida College of Medicine (Gainesville, FL). All patients underwent resection of the primary cancer followed by postoperative RT. The median follow-up period was 5.2years (range, 0.3-34years). RESULTS: Occult metastases were found in 18 (44%) of the 41 patients in the END group. There were 4 recurrences (10%) in the END group and 0 recurrence in the ENI group. Neck control rates at 5years were: END, 90%; ENI, 100%; and overall, 93% (p=0.1879). Cause-specific survival was 94% in the ENI group, 84% in the END group, and 86% for all patients (p=0.6998). There were 3 reported grade 3 or 4 toxicities. Two patients had a postoperative fistula and one patient had a grade 4 osteoradionecrosis that required a partial mandibulectomy. CONCLUSIONS: Patients with cNo high grade salivary gland carcinomas who are planned to undergo surgery and postoperative RT likely do not benefit from a planned neck dissection.
