Impact of late toxicities on quality of life for survivors of nasopharyngeal carcinoma.

ABSTRACT: BACKGROUND: To investigate the impact of physician-assessed late toxicities on patient-reported quality of life (QoL) for nasopharyngeal carcinoma (NPC) patients with long-term survival. METHODS: A cross-sectional survey of QoL and late toxicities was conducted in 242 NPC patients with disease-free survival of more than 5 years after treatment. The QoL was assessed by the European Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Late toxicities including neuropathy, hearing loss, dysphagia, xerostomia, and neck fibrosis were recorded based on the criteria of Common Terminology Criteria for Adverse Events version 4.0 (CTCAE v.4.0). The general linear model multiple analysis of variance (GLM-MANOVA) was performed to predict factors associated with the QoL. RESULTS: In the multifactor model of GLM-MANOVA, of the five late toxicities of CTCAE scales, neuropathy, hearing loss, and xerostomia were observed to be significantly associated with the overall outcome of the fifteen QLQ-C30 scales. A statistically significant trend (p <0.05) was observed, indicating that NPC survivors with more severe neuropathy, hearing loss or xerostomia had a worse outcome on global QoL, all five functional scales, and a variety of symptomatic scales. CONCLUSIONS: To improve QoL outcome for NPC survivors, the development of a modern radiotherapeutic technique should not only focus on reduction of the dose to the salivary glands, but also on anatomical structures that are involved in neuropathy and hearing loss.

Project description:Concerted research efforts over the last three decades have resulted in improved survival and outcomes for patients diagnosed with nasopharyngeal carcinoma (NPC). The evolution of radiotherapy techniques has facilitated improved dose delivery to target volumes while reducing dose to the surrounding normal tissue, improving both disease control and quality of life (QoL). In parallel, clinical trials focusing on determining the optimal systemic therapy to use in conjunction with radiotherapy have been largely successful, resulting in improved locoregional, and distant control. As a consequence, neoadjuvant chemotherapy (NACT) prior to definitive chemoradiotherapy has recently emerged as the preferred standard for patients with locally advanced NPC. Two of the major challenges in interpreting toxicity and QoL data from the published literature have been the reliance on: (1) clinician rather than patient reported outcomes; and (2) reporting statistical rather than clinical meaningful differences in measures. Despite the lower rates of toxicity that have been achieved with highly conformal radiotherapy techniques, survivors remain at moderate risk of persistent and long-lasting treatment effects, and the development of late radiation toxicities such as hearing loss, cranial neuropathies and cognitive impairment many years after successful treatment can herald a significant decline in QoL. Future approaches to reduce long-term toxicity will rely on: (1) identifying individual patients most likely to benefit from NACT; (2) development of response-adapted radiation strategies following NACT; and (3) anticipated further dose reductions to organs at risk with proton and particle therapy. With increasing numbers of survivors, many in the prime of their adult life, research to identify, and strategies to address the unmet needs of NPC survivors are required. This contemporary review will summarize our current knowledge of long-term toxicity, QoL and unmet needs of this survivorship group.

Project description:BackgroundNeoadjuvant chemotherapy (NACT) treatment in locoregionally advanced nasopharyngeal carcinoma (LA-NPC) can lead to considerable toxicity. Loss of skeletal muscle mass showed relevance with increased chemotherapy-related toxicity and poor survival in various cancer types, but its significance in NPC remains unclear. This study aimed to investigate the relationship between body composition parameters and the incidence of NACT toxicity in LA-NPC patients.MethodsNinety-six LA-NPC patients were retrospectively enrolled. All patients had pre-treatment abdominal computed tomography (CT) images to exclude distant metastasis. Lean body mass (LBM, kg) was estimated based on cross-sectional muscle area at the third lumbar vertebra (L3) level on CT, and skeletal muscle index (SMI, cm2/m2) was calculated. Doses of chemotherapeutics were normalized as dose/LBM (mg/kg). Grade 3-4 toxicity was defined as severe. The associations between body composition parameters and severe toxicities were assessed using univariate and multivariate logistic regression analyses. Optimal cutoff points were obtained with a receiver operating characteristic (ROC) curve.ResultsOf the 96 patients, 81.2% received the docetaxel + cisplatin (TP) regimen, and the rest received the gemcitabine + cisplatin (GP) regimen. Males had more LBM and a higher SMI at baseline, and females received a markedly higher dose of docetaxel and gemcitabine per kg LBM (P<0.001). With a cutoff value of 52.7 cm2/m2, patients with higher SMI showed lower risk of severe toxicity. For TP regimen group, those presented with grade 3-4 neutropenia had a higher dose per kg LBM. Univariate and multivariate analyses showed that the LBM-adjusted dose was significantly associated with severe neutropenia in the TP regimen group (P<0.001). The LBM-normalized docetaxel cutoff value of 2.64 mg/kg was a prominent predictor of ≥ grade 3 neutropenia (P=0.003), but a higher dose of docetaxel per kg LBM did not provide a better objective response rate.ConclusionsLA-NPC patients with lower SMI and higher dose of docetaxel per kg LBM are more likely to suffer from severe treatment-related toxicity. Higher docetaxel dose per kg LBM is a prominent predictor for severe neutropenia, but not for NACT response. LBM showed good potential in toxicity risk prediction and dose determination.

Project description:Parents of children with cancer desire information regarding the late effects of treatment. In the current study, the authors assessed parents' preparedness for late effects at least 5 years after their child's diagnosis.A cross-sectional survey was conducted of all eligible parents of children with cancer between April 2004 and September 2005 at Dana-Farber/Boston Children's Cancer and Blood Disorders Center within 1 year of diagnosis, and a follow-up questionnaire was administered at least 5 years later.Approximately 66% of parents of children who were still living, and who were able to be contacted, completed the follow-up questionnaire (91 of 138 parents). Approximately 77% of respondents (70 of 91 respondents) were parents of disease-free survivors and 23% (21 of 91 respondents) were parents of children with recurrent disease. The majority of parents believed they were well prepared for their child's oncology treatment (87%), but fewer felt prepared for future limitations experienced by their children (70%; P = .003 using the McNemar test) or for life after cancer (62%; P<.001). On bivariable analysis among parents of disease-free survivors, parents were more likely to believe themselves to be prepared for future limitations when they also reported that communication with the oncologist helped to address worries regarding the future (odds ratio, 4.50; P = .01). At the time of diagnosis, both parents and physicians underestimated a child's risk of future limitations; 45% of parents and 39% of clinicians predicted future limitations in physical abilities, intelligence, or quality of life, but at the time of the follow-up questionnaire >5 years later, 72% of children experienced limitations in at least 1 domain.Parents believe themselves to be less prepared for survivorship than for treatment. High-quality communication may help parents to feel more prepared for life after cancer therapy. Cancer 2016;122:2587-94. © 2016 American Cancer Society.
