Abstract
Background and Purpose:
To compare oncological outcome and voice quality among a uniform and well-defined subset of patients with T1 glottic carcinoma.
Patients and Methods:
Patients, affected by laryngeal glottic carcinoma, treated by laser CO2 surgery or radiotherapy, have been analyzed. Overall survival and disease-free survival were calculated. In order to verify differences in functional outcomes and voice quality, all patients were interviewed during their last follow-up visit during 2009 using the VHI (Voice Handicap Index) questionnaire. The data were analyzed using the MedCalc software.
Results:
A total of 143 patients were analyzed: 73 underwent surgery and 70 underwent radiotherapy. No statistically significant differences were found between the two groups in terms of overall survival and disease-free survival; dividing patients into stages T1a and T1b also made no difference. In order to evaluate the differences in outcomes for surgery and radiotherapy, patients were interviewed using the VHI questionnaire. Better scores for each category in the VHI were found for patients receiving radiotherapy compared to surgery (physical: p = 0.0023; functional: p < 0.0001; environmental: p < 0.001). The median VHI score for radiotherapy patients was 4, while for surgical patients it was 18 (p < 0.0001).
Conclusion:
This study confirms the well-known knowledge that results from radiotherapy and surgery in early glottic cancer treatment are equivalent. Furthermore, the role of patient preference in the treatment modality choice and the value of a multidisciplinary approach for a detailed and multi-oriented discussion with the patient are outlined.
Zusammenfassung
Hintergrund und Zielsetzung:
Es sollen das onkologische Ergebnis und die Sprachqualität in einer homogenen und gut definierten Gruppe von Patienten mit T1-Stimmbandkarzinomen verglichen werden.
Patienten und Methoden:
Patienten mit einem Glottiskarzinom, die sich einer CO2-Laser-Operation oder einer Radiotherapie unterzogen hatten, wurden analysiert. Das Gesamtüberleben und die krankheitsfreie Zeit wurden errechnet. Um Unterschiede im funktionellen Ergebnis und bezüglich der Sprachqualität zu quantifizieren, wurden alle Patienten während der letzten Nachsorge im Jahre 2009 dazu angehalten den VHI-(Voice Handicap Index-)Fragebogen auszufüllen. Diese Daten wurden mittels der MedCalc-Software bearbeitet.
Ergebnisse:
Insgesamt wurden 143 Patienten untersucht: 73 wurden operiert und 70 erhielten eine Strahelentherapie. Es konnte kein statistisch signifikanter Unterschied zwischen den zwei Gruppen bezüglich der Gesamtüberlebenszeit und der krankheitsfreien Zeit festgestellt werden; dies gelang auch nicht, wenn die Gruppen in Stadium T1a und T1b getrennt betrachtet wurden. Um die Unteschiede zwischen Operation und Radiotherapie zu evaluieren, wurde der VHI-Fragebogen verwendet. Es ließ sich zeigen, dass in jeder Kategorie des VHI-Fragebogens die Patienten, die strahlentherapiert wurden, bessere Ergebnisse erzielten als jene, die operiert wurden („physikalisch“: p = 0,0023; „funktionell“: p < 0,0001). Der durchschnittliche VHI-Score für strahlentherapierte Patienten ist 4, im Gegensatz zu 18 für operierte Patienten (p < 0,0001).
Zusammenfassung:
Diese Studie bestätigt die Erkenntnis, dass Radiotherapie und Operation beim Stimmbandkarzinom im frühen Stadium zu äquivalenten Ergebnissen führen. Weiterhin wird die Bedeutung des Patientenwunsches im Hinblick auf die Therapieoptionen und die Bedeutung eines multidiszplinären Therapieansatzes belegt.
