Methods:
Patients who had T4N0M0 Pancoast tumors invading the spine and underwent a single-stage posterior approach were retrospectively recruited. The following data were obtained and examined: demographics, tumor histology, preoperative and postoperative therapy, complications, spinal reconstruction technique, tumor resection extent, survival time, and disease recurrence.
Results:
Eighteen patients were included. The mean population age was 61±17 years, and the most common pathological type was adenocarcinoma (61.1%). Complete resection (R0) was obtained in 15 patients (83.3%), positive surgical margins (R1) were found in three patients (16.7%), and the 90-day mortality rate was 0%. Postoperative major complications were detected in 12 patients (66.7%), who required reoperation. The mean survival time was 67±24 months, but the median survival time was not reached. Among the patients, 10 (55.6%) are still alive at the end of the study. The 2- and 5-year actual survival rates were 59% (95% confidence interval [CI], 35.7%–82.3%) and 52.5% (95% CI, 28.4%–76.6%), respectively.
Conclusions
En bloc resection and spinal stabilization through a single-stage posterior approach might be effective for T4 Pancoast tumors invading the spine.
