A Prospective Randomized Trial of the Influence of Music on Anxiety in Patients Starting Radiation Therapy for Cancer.

PURPOSE: One of the most downloaded articles in 2017 from the International Journal of Radiation Oncology, Biology, and Physics was a study suggesting that music therapy during radiation therapy (RT) simulation substantially reduces anxiety. To further evaluate the potential of music's clinical efficacy in the context of radiation therapy, we conducted a randomized trial evaluating the influence of genre-based music chosen by the study participant on anxiety during the first RT treatment session with a method that is applicable to routine clinical practice. METHODS AND MATERIALS: We conducted a prospective randomized trial of music versus no music during the first RT treatment for cancer. We limited the study to women because prior studies document a higher rate of anxiety in female patients with cancer. Anxiety was evaluated before and after the first RT treatment using the State-Trait Anxiety Inventory (STAI) and Symptom Distress Thermometer (SDT). Patients randomized to music had their preferred genre of music played from a web-based application while in the treatment vault. RESULTS: In the study, 102 females were enrolled (51 with and 51 without music). Baseline high anxiety score before RT was recorded in 48% of patients using the STAI and 58% using the SDT. The percent decrease in mean STAI score was 16% with music versus 10% without music (P = .2197). The mean SDT percent changes were a 13% decrease with music versus a 2% increase without music (P = .3298). CONCLUSIONS: This study documents that high anxiety is common in women receiving RT for cancer and that music, as used in this study, does not reduce anxiety to a meaningful degree.

Positive Surgical Margins in Favorable-Stage Differentiated Thyroid Cancer.

OBJECTIVE: The significance of positive margin in favorable-stage well-differentiated thyroid cancer is controversial. We report outcomes of positive-margin patients with a matched-pair comparison to a negative-margin group. MATERIALS AND METHODS: A total of 25 patients with classic-histology papillary or follicular carcinoma, total thyroidectomy +/- node dissection, stage T1-3N0-1bM0, positive surgical margin at primary site, adjuvant radioactive iodine (I-131), and age older than 18 years were treated between 2003 and 2013. Endpoints were clinical and biochemical (thyroglobulin-only) recurrence-free survival. Matched-pair analysis involved a 1:1 match with negative-margin cases matched for overall stage and I-131 dose. RESULTS: Recurrence-free survival in positive-margin patients was 71% at 10 years. No patient was successfully salvaged with additional treatment. Only 1 patient died of thyroid cancer. Recurrence-free survival at 10 years was worse with a positive (71%) versus negative (90%) margin (P=0.140). CONCLUSIONS: Cure with a microscopically positive margin was suboptimal (71%) despite patients having classic-histology papillary and follicular carcinoma, favorable stage, and moderate-dose I-131 therapy.

Follicular thyroid carcinoma metastasis to the facial skeleton: a systematic review.

BACKGROUND: Follicular thyroid carcinoma (FTC) metastasis to the facial skeleton is exceedingly rare. A case of FTC metastasizing to the mandible is presented and a systematic review of the literature describing thyroid metastasis to the facial skeleton is performed. CASE PRESENTATION: A 73-year-old female presented with metastatic FTC to the mandible and underwent total thyroidectomy, segmental mandibulectomy, bone impacted fibular free flap reconstruction, and adjuvant radioactive iodine treatment. The PubMed database was searched for literature describing thyroid cancer with facial skeleton metastasis using the key words "thyroid," "cancer," "carcinoma," "metastasis," and "malignancy" with "oral cavity," "maxilla," "mandible," "sinus," "paranasal," and "orbit." Reports that only involved the soft tissues were excluded. Systematic review revealed 59 cases of well-differentiated thyroid cancer with facial skeleton metastasis: 35 mandibular metastases (21 = FTC), 6 maxilla metastases (2 = FTC), 9 orbital metastases (4 = FTC), and 11 paranasal sinus metastases (7 = FTC). Treatment included surgery, RAI, external beam radiotherapy (XRT), or a combination of these modalities. The one, two, and five-year survival rates were 100%, 79%, and 16%, respectively. CONCLUSION: Facial skeleton metastasis of FTC is a rare clinical challenge. Optimal treatment appears to include total thyroidectomy and resection of involved structures with or without adjuvant treatment.

Favorable Outcome of Hurthle Cell Carcinoma of the Thyroid Treated With Total Thyroidectomy, Radioiodine, and Selective Use of External-Beam Radiotherapy.

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.

Parameters that predict local control after definitive radiotherapy for squamous cell carcinoma of the head and neck.

PURPOSE: To analyze parameters that may influence the likelihood of local control after definitive radiotherapy for head and neck cancer. METHODS: Between April 1980 and January 2000, 404 patients were treated with definitive RT alone (358 patients) or combined with adjuvant chemotherapy (46 patients) at our institution and were followed up for 0.25 to 20.25 years (median, 3.5 years.) All living patients were followed up for at least 2 years. All patients had the primary tumor volume calculated on pretreatment CT. End points were local control after RT and local control after RT without a severe late complication. Parameters evaluated in multivariate analyses of these end points included primary site, T stage, primary tumor volume, N stage, histologic differentiation, fractionation schedule, adjuvant chemotherapy, and gender. RESULTS: The rates of local control and local control without a severe late complication after RT were significantly influenced by primary tumor volume for patients with cancer of the supraglottic larynx and true vocal cord. In contrast, the rates of local control and local control without severe complications for patients with tumors of the oropharynx and hypopharynx were less influenced by tumor volume. Multivariate analysis of the overall population revealed that the only parameter that was significantly related to the probability of local control after RT was T stage. Multivariate analyses stratified by primary site revealed that tumor volume significantly influenced local control for patients with cancers of the supraglottis (p =.0220) and glottis (p =.0042) but not for those with lesions of the tonsillar fossa/posterior tonsillar pillar (p =.0892), base of tongue (p =.9493), anterior tonsillar pillar/soft palate (p =.5909), and hypopharynx (p =.2282). CONCLUSIONS: The most important parameter that has an impact on local control after RT is T stage. Primary tumor volume also significantly influences the probability of local control in cancers of the supraglottis and glottis.
