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.

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.

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.

Background: In patients at high risk for regional node metastasis from squamous cell carcinoma (SCC) of the skin of the face, ear, or scalp, radiotherapy to the regional nodes is an alternative to parotid or neck surgery. Data on the efficacy of elective nodal radiotherapy in this setting are scarce such that there is no publication specifically addressing the subject. The purpose of our study is to fill this void in the skin cancer literature.

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.

Article Synopsis
  • Study aimed to evaluate the effectiveness of a standardized PET-CT program 12 weeks post-radiotherapy for patients with N2 squamous cell carcinoma of the oropharynx to determine the necessity of neck dissection.
  • Among 50 patients, the PET-CT's ability to detect residual disease showed 0% sensitivity and a 91% negative predictive value, indicating it was good at ruling out the need for further surgery.
  • The study concluded that a negative PET-CT can be a reliable indicator that neck dissection is unnecessary, as most recurrences occur over a year later, with a low success rate for salvage treatment.

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.

Background: When composite scalp and calvarial defects with dural or cortical brain exposure are encountered, active infection or indeterminate oncologic margins complicate the timing of scalp reconstruction. The purpose of this study was to evaluate the safety and efficacy of vacuum-assisted closure (VAC) therapy as a temporizing measure in these complex scalp defects with dural or cortical brain exposure and a hostile local wound environment.

Methods: From December 2012 to December 2013, all composite scalp and calvarial defects reconstructed by the senior author (D.

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.

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.

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.

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.

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.

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.
