Benign notochordal cell tumors (BNCTs) are considered to be benign intraosseous lesions of notochord origin; however, recent spine studies have suggested the possibility that some chordomas arise from BNCTs. Here, the authors describe two cases demonstrating histological features of BNCT and concomitant chordoma involving the clivus, which, to the best of the authors’ knowledge, have not been previously documented at this anatomical site.An 18-year-old female presented with an incidentally discovered clival mass. Magnetic resonance imaging revealed a 2.8-cm nonenhancing lesion in the upper clivus that was T2 hyperintense and T1 hypointense. She underwent an uneventful endoscopic transsphenoidal resection. Histologically, the tumor demonstrated areas of classic chordoma and a distinct intraosseous BNCT component. The patient completed adjuvant radiation therapy. Follow-up showed no recurrence at 18 months.A 39-year-old male presented with an incidentally discovered 2.8-cm clival lesion. The nonenhancing mass was T2 hyperintense and T1 hypointense. Surgical removal of the lesion was performed through an endoscopic transsphenoidal approach. Histological analysis revealed areas of BNCT with typical features of chordoma. Follow-up did not demonstrate recurrence at 4 years.These cases document histologically concomitant BNCT and chordoma involving the clivus, suggesting that the BNCT component may be a precursor of chordoma.

Adjuvant Radiation Therapy

Background:Uterine leiomyosarcoma (LMS) is associated with high rate of recurrence after surgical resection. The role of adjuvant radiation therapy in improving survival in women with uterine LMS is unclear.Methods:All cases of LMS treated from 1985 to 2005 at 11 regional medical centers were identified. Kaplan-Meier survival curves were constructed and compared with log-rank testing. Multivariate analysis was performed to account for the potential influence of confounding factors.Results:One hundred forty-seven patients with LMS were identified. The median age of diagnosis was 51 years with the stage distribution of stage I (n = 87), II (n = 9), III (n = 25), IV (n = 25), and unknown (n = 1). One hundred forty-three underwent total abdominal hysterectomy and bilateral salpingoophorectomy. Twenty-four (17%) of these patients received adjuvant pelvic irradiation, and 63 (44%) received adjuvant and/or palliative chemotherapy. With a median follow-up of 24 months (range, 1-249 months), the median survival for the entire group was 37 months. Cox proportional hazards modeling demonstrated the presence of high tumor grade and advanced stage adversely affected survival. Although the 5-year survival for patients who received adjuvant radiotherapy was significantly higher than those who did not (70% vs 35%), this survival advantage was not sustained as the curves crossed at 90-month follow-up. Pelvic recurrence rate was lower in the radiation group (18% vs 49%; P = 0.02).Conclusions:Adjuvant radiation therapy was associated with decreased pelvic failure and a modest improvement in 5-year survival, but did not impact overall survival with extended follow-up.

Definitive Management

✓ The practice of neuroendoscopy in the definitive management of cystic tumors and hydrocephalus has been well established. Resection of solid intraventricular tumors by a primary endoscopic technique, however, has rarely been demonstrated. The authors present the case of a 31-year-old woman in whom endoscopic resection of a posterior third ventricular ependymoma was successfully accomplished. Metastatic workup yielded no sites of dissemination, adjuvant radiation therapy was deferred, and the patient has been without radiographic evidence of disease after 6 months of follow up. Endoscopic resection of solid tumors appears feasible in select patients and warrants further evaluation.

Metaplastic Breast Carcinoma

Metaplastic breast cancer is rare, representing < 5% of breast cancer (only eight cases have been reported so far). We present here a 42-year-old female complaining of a painless lump in the right breast for the previous two months. Physical examination revealed a palpable mass. Lumpectomy was performed and histopathologic examination revealed metaplastic breast carcinoma with foci of chondrosarcoma. The patient received adjuvant radiation therapy and chemotherapy and is currently following up as an outpatient. We also discuss diff erentimaging diagnostic features of this specifi c type of breast cancer using mammography, ultrasonography, and magnetic resonance imaging.

e21521 Background: Adjuvant radiation therapy is an essential part of combined limb sparing treatment of STS. The recommended dose of radiation lies in the range of 60 Gy in standard fractionation of 1.8-2 Gy. Elderly or medically unfit patients often have difficulty in completing 6-7w of daily treatment. A prolonged course of radiation may be interrupted by acute side effects, which sometimes demands further extension of the overall course or even discontinuation of treatment. We intended to evaluate the efficacy of a hypofractionated adjuvant approach with radiation therapy for STS in the elderly and debilitated patients. Methods: 21 elderly patients were treated with a short course of adjuvant RT (39 to 48 Gy, 3 Gy per fraction) for STS. The medical records of the patients were retrospectively reviewed for the local or distant recurrence and side effects of RT. Results: Overall, the hypofractionated irradiation regimen of 39-48 Gy in 13-16 fractions was well tolerated with only 3 patients developing Grade 2-3 acute toxicity (mainly dermatitis). Three patients suffered from delayed Grade 2-3 toxicity (chronic pain, skin atrophy, teleangiectasiae) scaled according to CTSC. The mean time from the surgery until the initiation of RT was 65 days (SD 21.6). Mean RT time was 18.4 (SD 3) days. No delay of treatment due to acute toxicity was registered. All patients except for one were able to receive RT in the ambulatory setting. With a mean follow-up of 532 days (SD: 325), three local recurrences (14%) were detected. Three of eight patients with distant metastases died of sarcoma (graph 1). One patient with metastatic disease in the lung received salvage stereo tactic radiation therapy and was still alive 6 month after completion of SBRT with no evidence of disease. At a mean 532 days of follow up three local recurrences (14%) were detected .Eight patients (38%) had lung metastases during the observed period. Three of them died from metastatic disease. The hypofractionated radiation was well tolerated with minimum long term side effects. Conclusions: Hypofractionated adjuvant radiation appears to be an effective treatment in terms of local control in elderly and debilitated patients.

370 Background: In patients with muscle-invasive bladder cancer, local-regional failure (LF) has been reported to occur in up to 20% of patients following radical cystectomy. The goals of this study were to describe patterns of LF, as well as assess factors associated with LF in a cohort of patients with pT3-4 bladder cancer. This information may have implications towards the use of adjuvant radiation therapy. Methods: Patients with pathologic T3-4 N0-1 bladder cancer were examined from an institutional radical cystectomy database. Preoperative demographics and pathologic characteristics were examined. Outcomes included overall survival and LF. Local-regional failures were defined using follow-up imaging reports and scans, and the locations of LF were characterized. Variables were tested by univariate and multivariable analysis for association with LF and overall survival. Results: 334 patients had pT3-4 and N0-1 disease after radical cystectomy and bilateral pelvic lymph node dissection. Of these, 46% received perioperative chemotherapy. The median age was 71 and median follow up was 11 months. On univariate analysis, margin status, pT stage, pN stage, and gender were all associated with LF (p < 0.05), however, on multivariable analysis, only pT and pN stage were significantly associated with LF (p < 0.01). Three strata of risk were defined, including low-risk patients with pT3N0 disease, intermediate-risk patients with pT3N1 or pT4N0 disease, and high-risk patients with pT4N1 disease, who had 2-year incidence of LF of 12%, 33%, and 72%, respectively. The most common sites of pelvic relapse included the external/internal iliac LNs and obturator LN regions. Notably, 34% of patients with LF had local-regional only disease at the time of recurrence. Conclusions: Patients with pT4 or N1 disease have a 2-year risk of LF that exceeds 30%. These patients may be the most likely to benefit from local adjuvant therapies.

A 3.5-year-old wild born cheetah (Acinonyx jubatus), living in a large enclosure on a private Namibian farm, developed a large exophytic nodular neoplasm in its skin at the height of the left shoulder blade. We describe the clinical appearance, the surgical removal, and histological examination of the tumor, which was diagnosed as a moderately pigmented benign basal cell tumor. A three-year follow-up showed no evidence of recurrence after the surgery. Although neoplasia is reported in nondomestic felids, only very few concern cheetahs. So far, no case of basal cell tumor was described in this species.

The diagnosis and management of intraorbital foreign bodies are challenging for surgeons. Foreign bodies made of wood and those located close to the optic nerve are especially difficult to manage. Herein, we report our experience with the diagnosis and management of intraorbital wooden foreign bodies utilizing magnetic resonance imaging (MRI). A 50-year-old man presented to the emergency room with a laceration on his left upper eyelid. No foreign bodies were visible through the laceration, and computed tomography findings showed only evidence of cellulitis with abscess formation. Despite drainage and antibiotics, the cellulitis worsened; subsequently, we found multiple wooden foreign bodies on MRI. Surgical removal was performed, excluding those in the intraconal space to avoid optic nerve damage. The patient recovered well and has not experienced any ophthalmic complications at 1 year of follow-up.
