To define factors that acutely influenced swallowing function prior to and during concurrent chemotherapy and radiotherapy. Design: A summary score from 1 to 7 (the swallowing performance status scale [SPS]) of oral and pharyngeal impairment, aspiration, and diet, was assigned to each patient study by a single senior speech and swallow pathologist, with higher scores indicating worse swallowing. Generalized linear regression models were formulated to asses the effects of patient factors (performance status, smoking intensity, amount of alcohol ingestion, and age), tumor factors (primary site, T stage, and N stage), and treatment-related factors (radiation dose, use of intensity-modulated radiation therapy, response to induction chemotherapy, postchemoradiotherapy neck dissection, and preprotocol surgery) on the differences between SPS score before and after treatment. Setting: University hospital tertiary care referral center. Patients: The study included 95 patients treated under a multiple institution, phase 2 protocol who underwent a videofluorographic oropharyngeal motility (OPM) study to assess swallowing function prior to and within 1 to 2 months after the completion of concurrent chemotherapy and radiotherapy. Main Outcome Measures: Factors associated with swallowing changes after chemoradiotherapy. Results: The mean pretreatment and posttreatment OPM scores were 3.09 and 3.77, respectively. Patients with T3 or T4 tumors (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.15-0.95; P =.04) and a performance status of 1 or 2 (OR, 0.37; 95% CI, 0.15-0.91; P =.03) were less likely to have worsening of swallowing after chemoradiotherapy. There was a trend for worse swallowing with increasing age (OR, 1.04; 95% CI, 0.99-1.09; P=.08). Only T stage (T3 or T4) was associated with improved swallowing after treatment (OR, 8.96; 95% CI, 1.9-41.5; PϽ .001). Conclusion: In patients undergoing concurrent chemotherapy and radiotherapy, improved swallowing function over baseline is associated with advanced T stage.

Purpose: Dysphagia is a debilitating complication in head and neck cancer patients (HNCPs) that may cause a high mortality rate for aspiration pneumonia. The aims of this paper were to summarize the normal swallowing mechanism focusing on its anatomo-physiology, to review the relevant literature in order to identify the main causes of dysphagia in HNCPs and to develop recommendations to be adopted for radiation oncology patients. The chemotherapy and surgery considerations on this topic were reported in recommendations only when they were supposed to increase the adverse effects of radiotherapy on dysphagia. Materials and methods: The review of literature was focused on studies reporting dysphagia as a pretreatment evaluation and as cancer and cancer therapy related side-effects, respectively. Relevant literature through the primary literature search and by articles identified in references was considered. The members of the group discussed the results and elaborated recommendations according to the Oxford CRBM levels of evidence and recommendations. The recommendations were revised by external Radiation Oncology, Ear Nose and Throat (ENT), Medical Oncology and Speech Language Pathology (SLP) experts. Results: Recommendations on pre-treatment assessment and on patients submitted to radiotherapy were given. The effects of concurrent therapies (i.e. surgery or chemotherapy) were taken into account. Conclusions: In HNCPs treatment, disease control has to be considered in tandem with functional impact on swallowing function. SLPs should be included in a multidisciplinary approach to head and neck cancer.

Background: Intensity modulated radiotherapy (IMRT) has the perceived advantage of function preservation by reduction of toxicities in the treatment of laryngo-pharyngeal malignancies. The aim of the study was to assess changes in dysphagia from baseline (i.e. prior to start of treatment) at three and six months post treatment in patients with laryngo-pharyngeal malignancies treated with radical radiotherapy ± chemotherapy. Functional assessment of other structures involved in swallowing was also studied. Materials and methods: 40 patients were sampled consecutively. 33 were available for final analysis. Dysphagia, laryngeal edema, xerostomia and voice of patients were assessed at baseline and at three and six months after treatment. Radiation was delivered with simultaneous integrated boost (SIB) using volumetric modulated radiation therapy (VMAT). Concurrent chemotherapy was three weekly cisplatin 100 mg/m 2 . Results: Proportion of patients with dysphagia rose significantly from ...
Dose to Larynx Predicts for Swallowing Complications After Intensity-Modulated Radiotherapy
International Journal of Radiation Oncology*Biology*Physics, 2008
Purpose: To evaluate early swallowing after intensity-modulated radiotherapy for head and neck squamous cell carcinoma and determine factors correlating with aspiration and/or stricture. Methods and Materials: Consecutive patients treated with intensity-modulated radiotherapy with or without chemotherapy between September 2004 and August 2006 at the Dana Farber Cancer Institute/Brigham and Women's Hospital were evaluated with institutional review board approval. Patients underwent swallowing evaluation after completion of therapy; including video swallow studies. The clinical-and treatment-related variables were examined for correlation with aspiration or strictures, as well as doses to the larynx, pharyngeal constrictor muscles, and cervical esophagus. The correlation was assessed with logistic regression analysis. Results: A total of 96 patients were evaluated. Their median age was 55 years, and 79 (82%) were men. The primary site of cancer was the oropharynx in 43, hypopharynx/larynx in 17, oral cavity in 13, nasopharynx in 11, maxillary sinus in 2, and unknown primary in 10. Of the 96 patients, 85% underwent definitive RT and 15% postoperative RT. Also, 28 patients underwent induction chemotherapy followed by concurrent chemotherapy, 59 received concurrent chemotherapy, and 9 patients underwent RT alone. The median follow-up was 10 months. Of the 96 patients, 31 (32%) had clinically significant aspiration and 36 (37%) developed a stricture. The radiation dose-volume metrics, including the volume of the larynx receiving 50Gy(p=0.04andp=0.03,respectively)andvolumeoftheinferiorconstrictorreceiving50 Gy (p = 0.04 and p = 0.03, respectively) and volume of the inferior constrictor receiving 50Gy(p=0.04andp=0.03,respectively)andvolumeoftheinferiorconstrictorreceiving50 Gy (p = 0.05 and p = 0.02, respectively) were significantly associated with both aspiration and stricture. The mean larynx dose correlated with aspiration (p = 0.003). Smoking history was the only clinical factor to correlate with stricture (p = 0.05) but not aspiration. Conclusion: Aspiration and stricture are common side effects after intensity-modulated radiotherapy for headand-neck squamous cell carcinoma. The dose given to the larynx and inferior constrictors correlated with these side effects. Ó

Purpose: To objectively assess swallowing function after an intensive chemoradiation regimen for locally advanced head-and-neck cancer and to assess the clinical implications of swallowing dysfunction. Patients and Methods: Twenty-nine patients with nonresectable Stage IV head-and-neck cancer participated in a Phase I study of radiation, 70 Gy/7 weeks, concurrent with weekly gemcitabine. Because of a high rate of mucosal toxicity, reduced drug doses were delivered to subsequent patient groups: 300, 150, 50, and 10 mg/m 2 /week. Twenty-six of these patients underwent prospective evaluation of swallowing function with videofluoroscopy and esophagogram. Studies were performed pretherapy, early post-therapy (1-3 months), and late post-therapy (6 -12 months). Results: Complete tests were performed pretherapy in 22 patients, early post-therapy in 20, and late post-therapy in 13. Twenty-five patients had at least one post-therapy study. Post-therapy dysfunction was characterized by reduced inversion of the epiglottis, delayed swallow initiation and uncoordinated timing of the propulsion of the bolus, opening of the cricopharyngeal muscle, and closure of the larynx, all of which promoted aspiration during and after the swallow. In addition, reduced base-of-tongue retraction with reduced contact to the posterior pharyngeal wall and incomplete cricopharyngeal relaxation resulted in pooling in the pyriform sinuses and vallecula of residue, which was frequently aspirated after the swallow. Post-therapy aspirations were typically "silent," eliciting no cough reflex, or the cough was delayed and noneffective in expelling the residue. Aspiration was observed in 3 patients (14%) in the pretherapy studies, in 13 (65%) in the early post-therapy studies, and in 8 (62%) in the late post-therapy studies (aspiration rates post-therapy vs. pretherapy: p ؍ 0.0002). Six patients had pneumonia requiring hospitalization 1-14 months after therapy (median: 2.5 months), being the likely cause of death in 2 patients. Five cases of pneumonia occurred among 17 patients who had demonstrated aspiration in the post-therapy studies, compared with no cases of pneumonia among 8 patients who had not demonstrated aspiration (p ؍ 0.1). Of the 4 patients who had not undergone any post-therapy study, 1 developed pneumonia. Mucositis scores, prolonged tube feeding, presence of tracheostomy tube, and gemcitabine doses were not found to be related to aspiration or pneumonia risk. Conclusions: After intensive chemoradiotherapy, significant objective swallowing dysfunction is prevalent. It promotes aspiration, which may not elicit a cough reflex and may be associated with pneumonia. Aspiration pneumonia may be an underdocumented complication of chemoradiotherapy for head-and-neck cancer. Future studies should examine whether routine post-therapy videofluoroscopy and training aspirating patients in safe swallowing strategies can reduce this risk.

This retrospective analysis focusses on the impact of therapy on perceived long-term post-cancer treatment function. A validated questionnaire including items and components for the assessment of communicative ability, quality of voice and swallowing was sent to 129 patients. All patients were treated between 1998 and 2007. A total of 76 patients (58.9%) with carcinoma of the larynx or hypopharynx replied to the questionnaire. Data was evaluated retrospectively. Therapy delivered was definitive radio(chemo)therapy (defchRT/RT) (21/ 76, 28%), laryngectomy + radio(chemo)therapy (LE + chRT/RT) (28/76, 37%), or larynx conservation surgery + radio(chemo)therapy (LCS + chRT/RT) (27/76, 36%). Radiotherapy was administered using 2D-or 3D-conformal planning. The most common concomitant chemotherapy delivered was cisplatin + 5FU. For statistical analyses of the components, averages were calculated and tested using the Kruskal-Wallis test and the U-test of Mann and Whitney. Differences were assessed by the Monte Carlo method or Fisher's exact test. The single item rates were compared with Fisher's exact test. Mean follow-up was 56.7 months (range, 8-130 months). After defchRT/RT, patients trended towards more substantial-strong hoarseness compared with LCS + chRT/RT (P = 0.2). After LE, patients were dissatisfied with their artificial larynx/electrolarynx and the tone of their voice (P = 0.3, P = 0.07) and communicative ability (P = 0.005, P = 0.008) compared with those treated with defchRT/RT and LCS + chRT/RT, respectively. Dysphagia and additional percutaneous endoscopic gastrostomy (PEG) feeding were more frequent after defchRT/RT in comparison with the other two groups (P < 0.05). Voice quality and communicative ability were slightly worse after defchRT/RT and LE + chRT/RT, but satisfying with all treatment modalities. Further development of the therapy approach is necessary to reduce long-term side effects, with measures of post-treatment function as important endpoints.
