Acupuncture for Chemoradiation Therapy-Related Dysphagia in Head and Neck Cancer: A Pilot Randomized Sham-Controlled Trial.

INTRODUCTION: Dysphagia is common in head and neck cancer patients after concurrent chemoradiation therapy (CRT). This study evaluated the feasibility of conducting a randomized sham-controlled trial and collected preliminary data on safety and efficacy of acupuncture. PATIENTS AND METHODS: Head and neck cancer (HNC) patients with stage III-IV squamous cell carcinoma were randomized to 12 sessions of either active acupuncture (AA) or sham acupuncture (SA) during and following CRT. Patients were blinded to treatment assignment. Swallowing-related quality of life (QOL) was assessed using the MD Anderson Dysphagia Inventory (MDADI) total and subscale scores. RESULTS: Multiple aspects of trial feasibility were confirmed. Forty-two of 196 patients screened (21%) were enrolled and randomized to receive AA (n = 21) or SA (n = 21); 79% completed at least 10 of 12 planned acupuncture sessions; 81% completed the study follow-ups. The majority of patients reported uncertainty regarding their treatment assignment, with no difference between the AA and SA groups. Audits confirmed both AA and SA treatments were delivered with high fidelity. No serious acupuncture-related side effects were observed. MDADI total scores significantly improved from baseline to 12 months post-CRT in both groups (AA: +7.9; SA +13.9; p = .044, p < .001). Similar patterns were observed for the MDADI global subscale (AA: +25.0; SA +22.7; p = .001, p = .002). Intent-to-treat analyses suggested no difference between the treatment groups (p = .17, p = .76 for MDADI total and global scores, respectively). CONCLUSION: A sham-controlled randomized trial evaluating acupuncture in dysphagia-related QOL in HNC found the procedure to be feasible and safe. Further investigation is required to evaluate efficacy. IMPLICATIONS FOR PRACTICE: Dysphagia or swallowing difficulty is an important and common condition after concurrent chemoradiation therapy in head and neck cancer patients. In addition to current available supportive care, acupuncture may offer potential for treating dysphagia. This study demonstrated that both active acupuncture and sham acupuncture are safe and were associated with improved dysphagia-related quality of life from baseline to 12 months after concurrent chemoradiation therapy. This study was not designed to inform underlying specific versus nonspecific effects. Future larger-scale pragmatic clinical trials evaluating the effectiveness of acupuncture versus standard of care are warranted, and further mechanistic research is needed to understand how active versus purportedly sham acupuncture procedures affect dysphagia-related symptoms.

Thyroid carcinoma, version 2.2014.

These NCCN Guidelines Insights focus on some of the major updates to the 2014 NCCN Guidelines for Thyroid Carcinoma. Kinase inhibitor therapy may be used to treat thyroid carcinoma that is symptomatic and/or progressive and not amenable to treatment with radioactive iodine. Sorafenib may be considered for select patients with metastatic differentiated thyroid carcinoma, whereas vandetanib or cabozantinib may be recommended for select patients with metastatic medullary thyroid carcinoma. Other kinase inhibitors may be considered for select patients with either type of thyroid carcinoma. A new section on "Principles of Kinase Inhibitor Therapy in Advanced Thyroid Cancer" was added to the NCCN Guidelines to assist with using these novel targeted agents.

Acupuncture for dysphagia after chemoradiation in head and neck cancer: rationale and design of a randomized, sham-controlled trial.

INTRODUCTION: Dysphagia is a common side effect following chemoradiation therapy (CRT) in head and neck cancer (HNC) patients. Current dysphagia management includes swallowing therapy and dilation procedures, but these treatments have limitations. While acupuncture has been reported to positively impact swallowing function and quality of life (QOL) in patients with dysphagia, current evidence is inconclusive. MATERIAL AND METHODS: In an ongoing trial, 42 squamous cell carcinoma HNC patients, who are receiving platinum-based CRT with curative intent, are being recruited from a comprehensive cancer center. They are randomized to 12 sessions of either active acupuncture or to sham acupuncture during and following CRT over a 24-week period. Blinded research staff assesses outcomes at baseline, 20 weeks post-CRT (end of acupuncture), and 12 months after baseline (6-month follow-up). The primary outcome is change in M.D. Anderson Dysphagia Inventory score from baseline to 12 months. Secondary outcomes include QOL measures pertaining to HNC patients. In addition, a subset of study patients are tested for salivary flow rates and cytokines, including plasma transforming growth factor-ß1 and interleukin 6 (n=10 per arm), to preliminarily explore the biological mechanisms of acupuncture for dysphagia. DISCUSSION: This paper addresses unique challenges related to study design in nonpharmacological, sham-controlled acupuncture trials including development of evidence-based credible verum and sham treatment protocols, blinding, and assuring fidelity of treatment. Results of this study will inform the feasibility of conducting a large scale trial and will provide preliminary evidence regarding the value of acupuncture for dysphagia in HNC patients.

Acupuncture for dysphagia after chemoradiation therapy in head and neck cancer: a case series report.

BACKGROUND: Dysphagia is a common side effect following chemoradiation therapy (CRT) in patients with head and neck cancer (HNC). METHODS: In this retrospective case series, 10 patients with HNC were treated with acupuncture for radiation-induced dysphagia and xerostomia. All patients were diagnosed with stage III/IV squamous cell carcinoma. In all, 7 of 10 patients were percutaneous endoscopic gastrostomy (PEG) tube dependent when they began acupuncture. Manual acupuncture and electroacupuncture were used once a week. RESULTS: A total of 9 of 10 patients reported various degrees of subjective improvement in swallowing functions, xerostomia, pain, and fatigue levels. Overall, 6 (86%) of 7 PEG tube-dependent patients had their feeding tubes removed after acupuncture, with a median duration of 114 days (range 49 to 368 days) post CRT. One typical case is described in detail. CONCLUSIONS: A relatively short PEG tube duration and reduced symptom severity following CRT were observed in these patients. Formal clinical trials are required to determine the causality of the observations.

beta-Tubulin-II expression strongly predicts outcome in patients receiving induction chemotherapy for locally advanced squamous carcinoma of the head and neck: a companion analysis of the TAX 324 trial.

PURPOSE: TAX 324 was a phase III trial comparing induction chemotherapy (IC) with docetaxel, cisplatin, and fluorouracil (TPF) with cisplatin and fluorouracil (PF) followed by concomitant chemoradiotherapy in locally advanced squamous cell cancer of the head and neck (LASCCHN). This study evaluates a series of tumor markers in pretreatment biopsies from that trial TAX 324 and correlates expression with survival. METHODS: Pretherapy biopsy specimens were available for 265 of 501 participants. Expression of a series of six markers (p53, thymidylate synthase, glutathione s-transferase pi [GST-pi], Bcl 2, beta tubulin II [betaT-2], and HER2 neu) was evaluated by immunohistochemistry. RESULTS: For patients with low betaT-II expression, median overall survival (OS) was 58.6 months (95% CI, not reached [NR]), compared with 18.2 months for patients with high betaT-II expression (95% CI, 13.11 to 30.06: hazard ratio [HR], 2.39; 95% CI, 1.67 to 3.72; P < .0001). Progression-free survival in patients with low betaT-II expression was 43.2 months (95% CI, 24.4 to NR) versus 9.8 months (95% CI, 7.06 to 18.53) for high betaT-II expression, with a HR of 1.9 (95% CI, 1.43 to 2.77; P < .0001). The predictive value of betaT-II expression was greater in the TPF versus PF arm than in the PF arm. CONCLUSION: Increased tumor expression of betaT-II is strongly associated with adverse outcome in LASCCHN patients treated with IC, and our data suggest low expression of betaT-II may predict patients most likely to benefit from induction TPF therapy. Further, simple models which combine expression of betaT-II with a carefully defined set of additional immunohistochemical markers may have significant prognostic impact for patients with LASCCHN.

Seeking alternative biological therapies: the future of targeted molecular treatment.

In recent years targeted therapies have expanded treatment options for patients with squamous cell cancer of the head and neck (SCCHN) considerably and have led to clinically significant benefit. However, the multitude of new targeted drugs that have emerged and are in development also represent a challenge and many years of carefully conducted clinical studies will be needed to explore their full potential. This article summarizes the most important recent developments in the targeted treatment of SCCHN and provides an overview of pathways and promising potential targets that could impact the treatment of patients with SCCHN in the future.

Organ preservation and treatment toxicity with induction chemotherapy followed by radiation therapy or chemoradiation for advanced laryngeal cancer.

OBJECTIVES: The authors reviewed records of patients with advanced laryngeal cancer treated with induction chemotherapy (IC) and hyperfractionated radiation therapy (RT) or chemoradiation (CRT) to determine the rates of organ preservation and function. METHODS: A total of 29 patients with stage III (45%) and stage IV (55%) squamous cell carcinoma of the larynx (SCCL), were treated with IC and RT or CRT in 1 of 7 consecutive trials. Fifty-five percent had clinically node-positive disease. Fifty-five percent and 45% had T3 or T4 tumors, respectively. All received 3 cycles of platinum-based IC. Daily RT was given to 48%, twice-daily RT to 45%, and concomitant boost RT to 7%. CRT was carboplatin (28%) or docetaxel (28%). Those treated with twice-daily RT did not receive CRT. RESULTS: The median follow-up is 52 months. Overall survival is 66%. Relapse occurred in 12 patients (41%), and 6 underwent salvage laryngectomy (5 stage III, 1 stage IV). Fifty-nine percent of patients (17 of 29) are alive at last follow-up with an anatomically intact larynx, and 48% (14 of 29) are alive with a functional larynx. Of the 23 patients for whom detailed information on gastrostomy tube (g-tube) placement/removal was available, median time with g-tube was 12 months, and 15 of 23 patients (65%) had a g-tube for 6 months or more. Twenty-three of all 29 patients (79%) retained an anatomically intact larynx, but 7 of 23 (30%) never resumed their pretreatment organ function. The overall rate of functional organ preservation, regardless of survival, was 55% (16/29). The 7 of 29 patients (26%) who retained a nonfunctional larynx required permanent g-tube or were unable to return to pretreatment oral intake capability. Nine of 13 with T4 SCCL (69%) compared with 7 of 16 (44%) T3 SCCL retained a functional larynx. CONCLUSION: The rate of larynx preservation is high, but toxicity remains significant with IC followed by hyperfractionated RT or CRT in advanced laryngeal cancer. Half of all patients were alive, able to retain their larynx, and return to pretreatment function. Advanced stage was not an indicator of poor outcome.
