OBJECT A chordoma is an indolent primary spinal tumor that has devastating effects on the patient's life. These lesions are chemoresistant, resistant to conventional radiotherapy, and moderately sensitive to proton therapy; however, en bloc resection remains the preferred treatment for optimizing patient outcomes. While multiple small and largely retrospective studies have investigated the outcomes following en bloc resection of chordomas in the sacrum, there have been few large-scale studies on patients with chordomas of the mobile spine. The goal of this study was to review the outcomes of surgically treated patients with mobile spine chordomas at multiple international centers with respect to local recurrence and survival. This multiinstitutional retrospective study collected data between 1988 and 2012 about prognosis-predicting factors, including various clinical characteristics and surgical techniques for mobile spine chordoma. Tumors were classified according to the Enneking principles and analyzed in 2 treatment cohorts: Enneking-appropriate (EA) and Enneking-inappropriate (EI) cohorts. Patients were categorized as EA when the final pathological assessment of the margin matched the Enneking recommendation; otherwise, they were categorized as EI. METHODS Descriptive statistics were used to summarize the data (Student t-test, chi-square, and Fisher exact tests). Recurrence and survival data were analyzed using Kaplan-Meier survival curves, log-rank tests, and multivariate Cox proportional hazard modeling. RESULTS A total of 166 patients (55 female and 111 male patients) with mobile spine chordoma were included. The median patient follow-up was 2.6 years (range 1 day to 22.5 years). Fifty-eight (41%) patients were EA and 84 (59%) patients were EI. The type of biopsy (p < 0.001), spinal location (p = 0.018), and if the patient received adjuvant therapy (p < 0.001) were significantly different between the 2 cohorts. Overall, 58 (35%) patients developed local recurrence and 57 (34%) patients died. Median survival was 7.0 years postoperative: 8.4 years postoperative for EA patients and 6.4 years postoperative for EI patients (p = 0.023). The multivariate analysis showed that the EI cohort was significantly associated with an increased risk of local recurrence in comparison with the EA cohort (HR 7.02; 95% CI 2.96–16.6; p < 0.001), although no significant difference in survival was observed. CONCLUSIONS EA resection plays a major role in decreasing the risk for local recurrence in patients with chordoma of the mobile spine.

Abstract INTRODUCTION To evaluate outcomes of patients with primary chordomas treated with spine stereotactic radiosurgery (SRS) alone or in combination with surgery, drawing from a single-institution database to elucidate treatment options associated with durable radiographic control of these conventionally radioresistant tumors. Chordomas result in significant morbidity, with a high rate of local recurrence and potential for metastases. SRS as a primary treatment could save patients from extensive surgery. Spine SRS outcomes support exploration of its role in the durable control of these conventionally radioresistant tumors. METHODS Clinical records were reviewed for outcomes of patients with primary chordoma of the mobile spine and sacrum who underwent single-fraction SRS between 2006 and 2017. Radiographic local recurrence-free survival (LRFS), overall survival (OS), symptom response, and toxicity were assessed in relation to extent of surgery. RESULTS In total, 35 patients with de novo chordoma of the mobile spine (49%) and sacrum (51%) received SRS with a median post-SRS follow-up of 38.8 mo (range: 2.0-122.9). The median PTV dose was 24Gy (range: 18–24Gy). Overall, 12 patients (33%) underwent definitive SRS and 23 patients (66%) underwent surgery followed by adjuvant SRS. Surgical strategies included separation surgery prior to SRS, curettage/intralesional resection, and en bloc resection in 7, 6, and 10 patients, respectively. The 3- and 5-yr LRFS rates were 86.2% and 80.5% respectively. Among 32 patients receiving 24 Gy (91%), the 3- and 5-yr LRFS were 96.3% and 89.9%. The 3- and 5-yr OS rates were 90.0% and 84.3%. The symptom response rate to treatment was 88% for pain and radiculopathy. Extent or type of surgery was not associated with LRFS, OS, or symptom response rates (P > .05), but en bloc resection was associated with higher CTCAE v. 5.0 surgical toxicity compared to epidural decompression and curettage/intralesional resection (P = .03). The long-term = grade 2 SRS toxicity rate was 31%, including 17% grade 3 tissue necrosis, recurrent laryngeal nerve palsy, fracture, and secondary malignancy. CONCLUSION High-dose spine SRS offers the chance of durable radiographic control and effective symptom relief with acceptable toxicity for primary chordomas as either definitive or adjuvant therapy.

Urachal Adenocarcinoma

Urachal adenocarcinoma represents the third most common histological type of non-urotelial bladder cancer. A very low incidence of this disease and the lack of prospective studies have led to a rich and heterogeneous treatment history. Currently, the standard of care for these patients is represented by partial cystectomy en bloc with resection of the urachal ligament and total omphalectomy. The aim of this article is to present our experience and results in the management of patients with urachal adenocarcinoma. Between 2005 and 2015, 16 patients have undergone surgical treatment for urachal adenocarcinoma in “Fundeni” Clinical Institute and Madrid University Hospital “Infanta Sofia.” Partial cystectomy was performed in 11 (68.76%) patients, while radical cystectomy en bloc with omphalectomy was performed in 5 (31.25%) patients, which were not amendable to a limited resection. The Sheldon classification was used, as it provides appropriate disease staging and is the most commonly utilized. Postoperative pathological results showed that 7 (43.75%) patients had localized tumors, and more than one-third (37.5%) of the patients had locally advanced Sheldon III disease, while 3 patients had distant metastasis at the time of surgery. Lymph node involvement was present in 3 patients (18.75%). Mean follow-up time was 2.5 years, ranging from 4 months to 7.6 years. Three patients (18.75%) were lost to follow-up, without any documented signs of local or systemic recurrence and were cancer free at the time of the last evaluation. In cases with lymph node involvement, local recurrence or distant metastasis, patients underwent cisplatin- or 5-fluorouracil-based salvage chemotherapy. Surgical treatment represents the gold standard, while adjuvant chemotherapy has a limited impact on overall survival. The utility of navel resection is questionable due to the rarity of direct invasion or local recurrence.

Sacral Tumors

Sacral giant cell tumors are rare neoplasms, histologically benign but potentially very aggressive due to the difficulty in achieving a complete resection, their high recurrence rate, and metastization capability. Although many treatment options have been proposed,en blocexcision with tumor-free margins seems to be the most effective, being associated with long term tumor control, improved outcome, and potential cure. An exemplifying case of a 29-year-old female with progressive complaints of pain and paresthesias in the sacral and perianal regions, constipation, and weight loss for 6 months is presented. The surgical technique foren blocexcision of a large sacral giant cell tumor through a modified Kraske procedure with mid-sacrectomy and coccygectomy is described. Complete resection with wide tumor-free margins was achieved. At 5 years of follow-up the patient is neurologically intact, without evidence of local recurrence on imaging studies. A multidisciplinary surgical procedure is mandatory to completely remove sacral tumors. In the particular case of giant cell tumors, it allows minimizing local recurrence preserving neurovascular function, through a single dorsal and definitive approach.
