Stability of spinal bone metastases in breast cancer after radiotherapy: a retrospective analysis of 157 cases
Abstract
Purpose: This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system.
Methods: The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated.
Results: Eighty-five (54%) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70%) and 124 (79%) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5%) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83% after 5 years.
Conclusion: The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates.
Hintergrund: Die retrospektive Analyse untersuchte osteolytische Knochenmetastasen von Patienten mit Mammakarzinom der thorakalen und lumbalen Wirbelsäule nach Radiotherapie (RT) hinsichtlich Stabilität anhand eines validierten Scores.
Methoden: Die Stabilität von 157 osteolytischen Metastasen bei 115 Patienten mit Brustkrebs, behandelt von Januar 2000 bis Januar 2012, wurde retrospektiv anhand des Taneichi-Scores evaluiert. Prognostische Faktoren bezüglich Stabilität und Überlebensraten wurden analysiert.
Ergebnisse: Vor RT wurden 85 Läsionen (54 %) als instabil gewertet. Nach 3 und 6 Monaten wurden 109 (70 %) und 124 (79 %) Läsionen als stabil klassifiziert. Vor RT wurden 30 Frakturen gefunden, nach RT zeigten sich 7 weitere (4,5 %) pathologische Frakturen. Kein prognostischer Faktor hatte signifikanten Einfluss auf die Stabilität 6 Monate nach RT. Nach einer Beobachtungszeit von median 16,5 Monaten ergab sich aus der Kaplan-Meier-Berechnung eine Gesamtüberlebenszeit von 83 % nach 5 Jahren.
Schlussfolgerung: Die Mehrheit der Patienten zeigte eine verbesserte oder konstante Stabilität der befallenen Wirbelkörper nach 6 Monaten. Die analysierten Patienten zeigten nur geringe tumorassoziierte Einschränkungen während der Nachbeobachtungszeit und erreichten hohe Überlebenszeiten.
