PURPOSEnTo compare patterns of care for elderly patients aged ≥70xa0years with locally advanced head and neck cancer versus those of younger patients treated for the same disease.nnnMETHODS AND MATERIALSnThe medical records of 421 consecutive patients over the age of 50xa0years treated at a single institution between April 2011 and June 2016 for stage III/IV squamous cell carcinoma of the head and neck were reviewed. The primary treatment approach was compared using a t test statistic among 3 age cohorts: 50 to 59xa0years (118 patients); 60 to 69xa0years (152 patients); and 70xa0years and older (151 patients). Logistical regression was used to determine variables that influenced the likelihood of receiving surgery versus nonsurgical treatment, as well as radiation alone versus chemoradiation.nnnRESULTSnThere was no difference in sex, T stage, N stage, Karnofsky performance status, or the number of chronic comorbid conditions among the 3 age cohorts (P>.05 for all). A greater proportion of elderly patients aged ≥70xa0years were treated by radiation alone compared with those aged 50 to 59 and 60 to 69xa0years (44% vs 16% and 24%, P=.01). Increasing age was associated with a greater likelihood of receiving primary nonsurgical versus surgical treatment (odds ratio 1.023, 95% confidence interval 1.004-1.042) and radiation alone compared with chemoradiation (odds ratio 1.054; 95% confidence interval 1.034-1.075). Ten chemotherapy regimens were used concurrently with radiation for patients aged ≥70xa0years, including carboplatin/paclitaxel (19%), carboplatin/cetuximab (19%), cisplatin (17%), and cetuximab (17%).nnnCONCLUSIONSnDespite similar performance status and comorbidity burden compared with their younger counterparts, patients aged ≥70xa0years were more commonly treated with less-aggressive strategies, including radiation alone. The variability of concurrent chemotherapy regimens used further suggests that the standard of care remains to be defined for this population.

CASTLE Thyroid Tumor: A Case Report and Literature Review

Carcinoma showing thymus-like differentiation is a rare tumor of the thyroid gland, which is structurally similar to thymic tissue. Overall, it has a favorable prognosis. Radiotherapy has been shown to be an effective local treatment, but there have been reports of distant recurrence. It has been suggested that adding chemotherapy may decrease the risk of recurrence. Here, we present a case report of a patient with a large tumor and extrathyroidal extension. The patient was treated with surgery, radiotherapy, and cisplatin with acceptable toxicity. The patient is free of locally recurrent or distant disease at 3u2009years.

Purpose Head and neck surgery and radiation cause tissue fibrosis that leads to functional limitations and lymphedema. The objective of this study was to determine whether lymphedema therapy after surgery and radiation for head and neck cancer decreases neck circumference, increases cervical range of motion, and improves pain scores. Methods and materials A retrospective review of all patients with squamous cell carcinoma of the oral cavity, oropharynx, or larynx who were treated with high-dose radiation therapy at a single center between 2011 and 2012 was performed. Patients received definitive or postoperative radiation for squamous cell carcinoma of the oral cavity, oropharynx, or larynx. Patients were referred to a single, certified, lymphedema therapist with specialty training in head and neck cancer after completion of radiation treatment and healing of acute toxicity (typically 1-3 months). Patients underwent at least 3 months of manual lymphatic decongestion and skilled fibrotic techniques. Circumferential neck measurements and cervical range of motion were measured clinically at 1, 3, 6, 9, and 12 months after completion of radiation therapy. Pain scores were also recorded. Results Thirty-four consecutive patients were eligible and underwent a median of 6 months of lymphedema therapy (Range, 3-12 months). Clinically measured total neck circumference decreased in all patients with 1 month of treatment. Cervical rotation increased by 30.2% on the left and 27.9% on the right at 1 month and continued to improve up to 44.6% and 55.3%, respectively, at 12 months. Patients undergoing therapy had improved pain scores from 4.3 at baseline to 2.0 after 1 month. Conclusions Lymphedema therapy is associated with objective improvements in range of motion, neck circumference, and pain scores in the majority of patients.
