Decrease in treatment intensity predicts worse outcome in patients with locally advanced head and neck squamous cell carcinoma undergoing radiochemotherapy

PURPOSE: Radiochemotherapy (RCT) is an effective standard therapy for locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Nonetheless, toxicity is common, with patients often requiring dose modifications. METHODS: To investigate associations of RCT toxicities according to CTCAE version 5.0 and subsequent therapy modifications with short- and long-term treatment outcomes, we studied all 193 patients with HNSCC who received RCT (70 Gy + platinum agent) at an academic center between 03/2010 and 04/2018. RESULTS: During RCT, 77 (41%, 95% CI 34-49) patients developed at least one ≥ grade 3 toxicity, including seven grade 4 and 3 fatal grade 5 toxicities. The most frequent any-grade toxicities were xerostomia (n = 187), stomatitis (n = 181), dermatitis (n = 174), and leucopenia (n = 98). Eleven patients (6%) had their radiotherapy schedule modified (mean radiotherapy dose reduction = 12 Gy), and 120 patients (64%) had chemotherapy modifications (permanent discontinuation: n = 67, pause: n = 34, dose reduction: n = 7, change to other chemotherapy: n = 10). Objective response rates to RCT were 55% and 88% in patients with and without radiotherapy modifications (p = 0.003), and 84% and 88% in patients with and without chemotherapy modifications (p = 0.468), respectively. Five-year progression-free survival estimates were 20% and 50% in patients with and without radiotherapy modifications (p = < 0.001), and 53% and 40% in patients with and without chemotherapy modifications (p = 0.88), respectively. CONCLUSIONS: Reductions of radiotherapy dose were associated with impaired long-term outcomes, whereas reductions in chemotherapy intensity were not. This suggests that toxicities during RCT should be primarily managed by modifying chemotherapy rather than radiotherapy

Outpatient Pulmonary Rehabilitation in Patients with Persisting Symptoms after Pulmonary Embolism

Background:Patients with pulmonary embolism (PE) may suffer from long-term consequences, including decreased functional capacity. Data on pulmonary rehabilitation (PR) in patients with PE are scarce, and no data on outpatient PR are available so far.Methods:We analyzed data of 22 PE patients who attended outpatient PR due to exertional dyspnea. Patients underwent a multi-professional 6-week PR program. The primary outcome was change in 6-min walk test (6MWT). Secondary outcomes included changes in strength and endurance tests. To assess long-term benefits, follow-up was performed a median of 39 months after PR.Results:Patients started PR a median of 19 weeks after the acute PE event. Their median age was 47.5 years, 33% were women and all presented with NYHA (New York Heart Association) class II and higher. After PR, patients showed significant and clinically relevant improvements in 6MWT (mean difference: 49.4 m [95% CI 32.0-66.8]). Similarly, patients increased performance in maximum strength, endurance and inspiratory muscle strength. At long-term follow-up, 78% of patients reported improved health.Conclusion:We observed significant improvements in exercise capacity in PE patients undergoing outpatient PR. The majority of patients also reported a long-term improvement in health status. Prospective studies are needed to identify patients who would benefit most from structured PR.Thrombosis and Hemostasi
