Organ Preservation and Late Functional Outcome in Oropharyngeal Carcinoma: Rationale of EORTC 1420, the "Best of" Trial.

ABSTRACT: Dysphagia represents one of the most serious adverse events after curative-intent treatments with a tremendous impact on quality of life in patients with head and neck cancers. Novel surgical and radiation therapy techniques have been developed to better preserve swallowing function, while not negatively influencing local control and/or overall survival. This review focuses on the current literature of swallowing outcomes after curative treatment strategies. Available results from recent studies relevant to this topic are presented, demonstrating the potential role of new treatment modalities for early- and intermediate-stage oropharyngeal cancers. Based on this, we present the rationale and design of the currently active EORTC 1420 "Best of" trial, and highlight the potential of this study to help prioritizing either surgery- or radiation-based treatment modalities for the treatment of oropharyngeal cancer in the future.

Project description:Purpose:This study aimed to compare the swallowing function in patients with human papillomavirus-associated oropharyngeal squamous cell carcinoma treated with de-intensified chemoradiation therapy (6 weeks, 60?Gy) versus those receiving standard-of-care chemoradiation therapy (7 weeks, 70?Gy). Methods and materials:A retrospective review was conducted of 78 patients with human papillomavirus-associated oropharyngeal squamous cell carcinoma with modified barium swallow studies pretreatment and 6 to 8 weeks posttreatment. The swallowing function was objectively scored for penetration, aspiration, and pharyngeal residue. Forty patients received de-intensified chemoradiation therapy (60?Gy image guided radiation therapy with weekly cisplatin 30?mg/m2) and 38 patients received standard-of-care chemoradiation therapy (70?Gy image guided radiation therapy with chemotherapy of the medical oncologist's choosing). Univariate and multivariate analyses were performed to detect differences between the cohorts with regard to laryngeal penetration, aspiration, and pharyngeal residue. A multivariate logistic regression was used to determine the overall effect of treatment on the swallowing function. Patient-reported swallowing outcomes in de-intensified cohort were assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Module for Head and Neck Cancer and the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events questionnaires. Results:Patients treated with de-intensified chemoradiation therapy were associated with a suggestion of lower risk of developing overall swallowing dysfunction (odds ratio [OR], 0.62; P?=?.07), laryngeal penetration (OR, 0.63; P?=?.12), and pharyngeal residue (OR, 0.61; P?=?.08). The mean pre- and 2-year post-European Organisation for Research and Treatment of Cancer Quality of Life scores pertaining to swallowing (1-4 scale, higher worse) in the de-intensified cohort were 1.4 and 1.2 for liquids; 1.2 and 1.1 for purees; 1.5 and 1.7 for solids, 1.0 and 1.3 for choked when swallowing; and 9.0 and 10.8 for composite score, respectively. The mean pre- and 2-year post-Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events swallowing difficulty scores (1-5 scale, with higher scores being worse) were 1.5 and 1.8, respectively. Conclusions:Compared with 7 weeks of 70?Gy, 6 weeks of 60?Gy de-intensified chemoradiation therapy appears to better preserve the baseline swallowing function (per objective modified barium swallow assessment). Patients treated with de-intensified chemoradiation therapy reported minimal changes in swallowing function.

Project description:BackgroundHigh dose chemoradiotherapy offers a curative chance for patients with rectal cancer that are unfit or unwilling to undergo surgical resection, yet its long-term survival and functional outcomes have been rarely investigated.MethodsPatients with non-metastatic rectal adenocarcinoma who received pelvic radiation for curative intent from April 2006 to July 2017 were retrospectively investigated. Survival rates were analyzed using the Kaplan-Meier method. Quality of life and functional outcomes were evaluated using the EORTC quality of life questionnaire.ResultsA total of 57 patients were included, with a median age of 59.0 (range, 29-84) years. The numbers of patients who were diagnosed as stage I, II and III were 5 (8.8%), 16 (28.1%) and 36 (63.2%), respectively. 53 (93.0%) patients had tumor located within 5 cm from the anal verge. All patients received fluorouracil-based concurrent chemoradiotherapy with a median radiation dose of 80 (range, 60-86) Gy. All kinds of grade 3-4 adverse events occurred in 18 (31.6%) patients. 42 (73.7%) patients achieved a clinical complete response after chemoradiotherapy. After a median follow-up of 43.5 (range 14.9-163.2) months, 12 (21.1%) patients had local progression and 11 (19.3%) developed distant metastasis. The 3-year local recurrence-free survival and distant metastasis-free survival were 77.3% (95% CI, 65.7-88.8%) and 79.2% (95% CI, 68.2-90.2%), while the 3-year progression-free survival, cancer-specific survival, overall survival were 61.9% (95% CI, 48.8-75.0%), 93.1% (95% CI, 85.8-100.0%) and 91.4% (95% CI, 83.6-99.2%), respectively. For patients who had tumor located within 3 cm from the anal verge, the sphincter preservation rate was 85.3% at last follow-up. Long-term adverse events mainly were anal blood loss. 21 patients completed the quality-of-life questionnaire and had a score of the global health status of 78.57 ± 17.59. Of them, 95.2% reported no urinary incontinence and 85.7% reported no fecal incontinence.ConclusionsHigh dose chemoradiation demonstrated promising survival outcomes with acceptable short-term and long-term side effects, and satisfying long-term functional outcomes and quality of life. It could be considered as a non-invasive alternative for rectal cancer patients who refuse surgery.
