Article: Xerostomia after radiotherapy : What matters-mean total dose or dose to each parotid gland?
[show abstract] [hide abstract]
ABSTRACT: PURPOSE: Xerostomia is a debilitating side effect of radiotherapy in patients with head and neck cancer. We undertook a prospective study of the effect on xerostomia and outcomes of sparing one or both parotid glands during radiotherapy for patients with squamous cell carcinoma of the head and neck. METHODS AND MATERIALS: Patients with locally advanced squamous cell carcinoma of the head and neck received definitive (70 Gy in 2 Gy fractions) or adjuvant (60-66 Gy in 2 Gy fractions) curative-intent radiotherapy using helical tomotherapy with concurrent chemotherapy if appropriate. Group A received < 26 Gy to the left and right parotids and group B received < 26 Gy to either parotid. RESULTS: The study included 126 patients; 114 (55 in group A and 59 in group B) had follow-up data. There were no statistically significant differences between groups in disease stage. Xerostomia was significantly reduced in group A vs. group B (p = 0.0381). Patients in group A also had significantly less dysphagia. Relapse-free and overall survival were not compromised in group A: 2-year relapse-free survival was 86% vs. 72% in group B (p = 0.361); 2-year overall survival was 88% and 76%, respectively (p = 0.251). CONCLUSION: This analysis suggests that reducing radiotherapy doses to both parotid glands to < 26 Gy can reduce xerostomia and dysphagia significantly without compromising survival. Sparing both parotids while maintaining target volume coverage and clinical outcome should be the treatment goal and reporting radiotherapy doses delivered to the individual parotids should be standard practice.Strahlentherapie und Onkologie 01/2013; · 3.56 Impact Factor -
Article: Global quality of life during the acute toxicity phase of multimodality treatment for patients with head and neck cancer: can we identify patients most at risk of profound quality of life decline?
[show abstract] [hide abstract]
ABSTRACT: Treatment intensification has improved outcomes for patients with head and neck cancer (HNC), but little has been reported on health-related quality of life (QoL) consequences. We investigated changes in QoL after (chemo)radiotherapy to identify patient characteristics that predict those whose QoL deteriorates most profoundly in the acute post-treatment period. Patients with locally advanced HNC treated with curative intent received intensity-modulated radiotherapy (60-70 Gy) in this prospective study. (Chemo)radiotherapy was either definitive or adjuvant. Induction chemotherapy consisted of three cycles of docetaxel, cisplatin, and 5-fluorouracil; responders received (chemo)radiotherapy; nonresponders underwent salvage surgery followed by (chemo)radiotherapy if appropriate. Patients completed the EORTC QLQ-C30 and HNC-specific HN35 module before and at the end of (chemo)radiotherapy and 6-8 weeks after therapy completion. Ninety-five patients participated. At baseline, patients reported significantly lower Global health status, functioning, and symptom scale scores than a reference German population (all p<0.001). At the end of (chemo)radiotherapy, patients had significantly lower QoL scores vs. baseline on all functioning scales (p<0.05). Most symptom and HN35 scores worsened during (chemo)radiotherapy but many recovered 6-8 weeks post-treatment. QoL deteriorated more in patients with high vs. low baseline QoL; no clinical or sociodemographic characteristics of patients most likely to experience a significant deterioration in QoL during treatment were identified. These standard QoL instruments did not predict patients at risk of profound global QoL impairments during acute treatment. Other than baseline QoL, no patient characteristics associated with significant QoL deterioration were identified.Oral Oncology 04/2012; 48(9):898-904. · 2.86 Impact Factor
