Introduction: Sacral chordoma is a rare low-to-intermediate grade malignant tumour. The mainstay of treatment is still surgery with en bloc and wide resection margins, which can grant the best chances of a long-term control or cure of this disease. The first aim of this paper is to collect data about survival, time to local recurrence and metastasis among patients affected by sacral chordoma and primarily treated with surgery. The second aim is to analyze the influence of level resection, tumor volume and surgical margins on local recurrence.Materials and Methods: The study population was composed of 14 patients treated with sacral chordoma resection at the National Tumour Institute of Naples-Pascale (Italy) from January 2000 to June 2013. The median follow-up was 84 months (range 24-132 months). The follow-up was characterized by: standard radiographs, MRI, and a CT scan of the chest annually. Time to recurrence or metastasis was calculated from the date of resection to the date of diagnosis of first recurrence or metastasis.Results: Out of all the patients, six died (42.86 %) during the follow-up; 6 (42.86 %) had local recurrence; 4 (28.57 %) had metastasis. At univariate analysis wide surgical margins (R0) were associated with increased survival up to a local recurrence (OR = 0.0286; 95 % CI = 0.0014-0.5739; P = 0.026); the level of resection (OR = 3.33; 95 % CI = 0.3619-30.7025; P = 0.592) and tumour volume (P = 1) did not show a statistically significant correlation.Discussion: Based on our experience, we hope all patients to be treated by surgery, the only good standard treatment of this disease. The resection should result in margins as wide as possible. For these reasons, it is essential for this disease to be treated in highly specialized centres because only a complete surgery can offer a chance to care for these patients.Conclusions: Solid survival at long-term follow-up can be achieved by a surgical resection performed with wide margins.

Purpose: For adult spinal deformity (ASD) patients receiving operative (op) and non-operative (non-op) treatment, the relationship between HRQoL measures, complications and self-reported satisfaction remains unclear. The objective of this analysis is to study nonlinear association dynamics between ASD patient satisfaction, HRQoL, and complications over a two-year follow-up period.Methods: From a prospective multicenter international adult spinal deformity database, all patients with 2-year follow-up data on satisfaction (21st question of SRS-22r) were identified and included. A total of 12 LOESS (local polynomial fit) regressions were performed between patient satisfaction (SRS22 item 21) and HRQoL measures (ODI, SF36PCS and SRS22 subtotal) interacting with surgery at baseline, 6 months and 1 and 2 years of follow-up.Results: A total of 856 patients (527 op and 329 non-op) were included. At baseline, satisfaction was lower for patients scheduled for surgery even when HRQL was similar to those elected for conservative treatment. The nonlinear correlations showed that for similar PROMs, op patients reached higher satisfaction levels during follow-up, especially at six months. In fact, at six months operated patients with a deterioration of their initial PROMs had some improvement in their satisfaction, which could not be further observed at the end of follow-up.Conclusions: Satisfaction does not correlate well with other PROMs, and it might be subject to other external factors not directly related to treatment. Even if patient satisfaction is important in evaluating well-being and patient's experience with medical care, it should not be considered as an isolated proxy to measure quality of treatment.
