BACKGROUND Spinal extradural hemangioblastomas (HBs) are quite uncommon, with most reported cases involving the thoracic and lumbar areas. Therefore, the presence of a dumbbell-shaped pure extradural cervical HB is exceptional, making preoperative diagnosis particularly challenging. OBSERVATIONS The authors report a case of a 27-year-old woman who presented to their outpatient clinic with progressive cervicobrachialgia and numbness in the left arm. Magnetic resonance imaging showed a C5–6 intradural extramedullary lesion, and, despite some atypical features, the diagnosis of a possible neurogenic tumor was made. A multidetector computed tomography scan and angiography confirmed the expansion and remodeling of the left neural foramen as well as the highly vascularized nature of the mass. Preoperative embolization of the lesion was performed. Complete tumor resection was accomplished, followed by a C5–6 posterior fusion. Histopathology and immunohistochemistry revealed an HB. LESSONS HBs should be considered among the differential diagnosis of cervical extradural tumors. Exhaustive preoperative workup and surgical planning are decisive in order to attain gross-total resection with favorable outcomes.

: Osteosarcoma of the jaws (OSJ) is a relatively rare disease, accounting for between 2% and 10% of all cases of osteosarcoma, it is morphologically and radiologically identical to the trunk and extremity variant, but distinct in several crucial aspects. : The lesion is characterized by sarcomatous cells which produces a variable amount of osteoid bone. It arises centrally within the bone and can be subdivided into osteoblastic, chondroblastic and fibroblastic subtype, depending on the predominant cell type. : Radiographically, these tumors display a spectrum of bone changes from well-demarcated borders to lytic bone destruction with indefinite margins and variable cortical bone erosion or, in some cases, images of sclerotic bone. Therapeutic options for OSJ include surgery, chemotherapy and radiotherapy, which are employed according to age of the patient, histological classification and localization of the tumor. Today there is no a general consensus in the treatment guidelines for the OSJ though surgery represents the key of the treatment. The main prognostic factor deeply influencing the patient's prognosis remains the complete tumor resection with negative surgical margins. : The aim of the present review is to describe the state of the art regarding diagnostic and surgical treatment aspects of the primary osteosarcoma of the jaws.

Cardiac leiomyosarcoma is an extremely rare tumor with a poor prognosis. An 18-year-old female patient was admitted to our clinic with a left atrial leiomyosarcoma extending to the right lower pulmonary veins. We performed complete tumor excision by the right anterolateral mini-thoracotomy approach using minimally invasive techniques. After pathological confirmation of the tumor, right lower lobectomy was performed with the same incision one week later to prevent recurrence. Although no tumor remnant was found in the lobectomy specimen, adjuvant chemotherapy was started. No recurrence was detected during the 12-month follow-up. In conclusion, the right submammarian minithoracotomy approach has the advantages of its less invasive nature and suitability for complete tumor resection with lobectomy.

ObjectiveComplete tumor resection is considered essential in the management of patients with ovarian clear-cell carcinoma. There is a debate regarding whether patients with recurrent ovarian clear-cell carcinoma benefit from secondary cytoreductive surgery.MethodsDetails of patients with clear-cell carcinoma were collected by the Tokai Ovarian Tumor Study Group (Nagoya University Hospital and 13 affiliated institutions) and evaluated between January 1990 and December 2015. Histology was confirmed after central pathological review. The primary endpoint of the study was disease-free survival after secondary cytoreductive surgery. Distributions of events were evaluated using the χ2 test. Survival analysis was based on the Kaplan-Meier method. Survival curves were compared using the log-rank test. A value of p<0.05 was considered significant.ResultsA total of 169 patients who underwent secondary cytoreductive surgery (N=25) or medical management (N=144) for recurrent clear-cell carcinoma were collected. The median age for patients undergoing secondary cytoreductive surgery was 50 years (range 35–66). Overall, 18 patients had complete resection. In patients who underwent secondary cytoreductive surgery, the median disease-free and post-recurrence survival periods were 10.9 months and 21.2 months, respectively. Moreover, among 18 patients who underwent complete resection, seven showed no evidence of disease during the observation periods. The median post-recurrence survival periods of patients with complete or incomplete resection were 30.1 months and 10.4 months, respectively (p=0.002). On stratification by the recurrence site, patients with intraperitoneal recurrence showed poorer post-recurrence survival than those with recurrence at other sites (p=0.016). However, comparison between the secondary cytoreductive surgery group versus the medical management group showed there was no difference in post-recurrence survival, even when considering complete tumor resection (p=0.114).ConclusionPatients with intraperitoneal recurrence or incomplete tumor resection had the worst survival after secondary cytoreductive surgery.

We present the case of a 30-year-old male patient with an almost complete destruction of the calvarial bone through an anaplastic meningioma diagnosed in line with dizziness. Neuroimaging revealed an extensive growing, contrast enhancing lesion expanding at the supra- and infratentorial convexity, infiltrating and destroying large parts of the skull, and infiltrating the skin. Due to progressive ataxia and dysarthria with proven tumor growth in the posterior fossa in the continuing course, parts of the tumor were resected. A surgical procedure with the aim of complete tumor resection in a curative manner was not possible. Six months after the first operation, due to a new tumor progression, most extensive tumor resection was performed. Due to the aggressive and destructive growth with a high rate of recurrence and tendency of metastases, anaplastic meningiomas can be termed as malignant tumors. The extrinsic growth masks the tumor until they reach a size, which makes these tumors almost unresectable. In the best case scenarios, the five-year survival is about 50%. With the presented case, we would like to show the aggressive behavior of anaplastic meningiomas in a very illustrative way. Chemotherapy, radiotherapy, and surgery reach their limits in this tumor entity.

10556 Background: Imatinib benefits the patients with metastatic GIST but whether it is effective in the adjuvant setting after complete tumor resection of primary GIST is questionable. Methods: Patients who had undergone complete tumor resection with intermediate or high risk of recurrence (define) were enrolled in a single-center non-randomized open contrast study. Patients had adjuvant therapy with imatinib (400mg once a day) for 3 years commencing within 12 weeks of tumor resection, or had follow-up alone. We performed c-kit and PDGFRA mutation analysis for patients with archival tumor samples. The primary objective was recurrence-free survival (RFS) and the second objective was correlation of gene mutation profile with efficacy of adjuvant therapy. Results: One hundred and five patients were enrolled: 56 patients in adjuvant therapy group and 49 patients in control group. Median follow-up was 30 months (range 12–62); Median treatment duration in adjuvant therapy group were 20 months (range 12–36); There was relatively higher 1-year and 2-year RFS in the adjuvant therapy group compared with the control group (100% vs 89.8%,94.4% vs 60.0%) (Log-RankP< 0.001). Hazard risk was 0.13 (95% CI 0.039–0.438, P= 0.001) in Cox proportional hazard regression model. For further sub-group analysis, Log-rank and Cox regression analysis showed that adjuvant therapy could significantly decrease recurrence risk in patients with high risk disease (define)(2-year RFS: 91.5% vs 46,2%, Log-Rank: P<0.001, HR:0.107 (95%CI 0.031–0.370), P<0.001). c-kit and PDGFRA mutation were analyzed in forty-nine patients. There was a better survival benefit from adjuvant therapy for patients with c-kit exon 11 mutation. Conclusions: Adjuvant therapy with imatinib can improve 1-year and 2-year recurrence-free survival for patients with an intermediate or high risk of recurrence after complete tumor resection.

Abstract OBJECTIVE Hemangiomas of the brachial plexus are very rare, and there has not been a collection of multiple cases published in the literature to date. Extraneural brachial plexus hemangiomas typically present with similar signs and symptoms as nerve sheath tumors, including pain, paresthesia, and occasionally weakness, in addition to nonspecific imaging findings, making their diagnosis difficult. Exploratory surgery can lead to significant bleeding and nerve injury when a hemangioma or an associated aneurysm is encountered intraoperatively. We present 5 cases of extraneural hemangiomas causing brachial plexopathy, including pre-, intra-, and postoperative decision making, with an emphasis on diagnostic and management issues as well as outcomes. METHODS A retrospective review was performed of 5 patients who underwent surgery at a university teaching hospital between 1995 and 2007 for exploration of brachial plexus lesions that were confirmed to be hemangiomas at pathological examination. RESULTS All 5 patients presented with findings on history, physical examination, imaging, and electromyography suggesting a diagnosis of nerve sheath tumor. Two patients had biopsies (1 needle, 1 open), both of which were nondiagnostic. Three patients underwent digital subtraction angiography with successful preoperative embolization. Each patient had a complete or a radical subtotal tumor resection, and all were intact neurologically after surgical resection. Pathological evaluation identified 3 venous hemangiomas, 1 hemangioma with arteriovenous malformation features, and 1 Masson hemangioma associated with a large aneurysm. CONCLUSION Extraneural hemangiomas of the brachial plexus are very rare, but a high index of suspicion and appropriate preoperative evaluation, including angiography with the option for embolization, can result in decreased intraoperative hemorrhage and better patient outcomes.
