The prognostic implications of Hyam’s subtype for patients with Kadish stage C esthesioneuroblastoma
Gurvinder Kaur Ari J. Kane Michael E. Sughrue Michelle Madden Michael C. Oh Matthew Z. Sun Michael Safaee Ivan El-Sayed Manish Aghi Michael W. McDermott Mitchel S. Berger Andrew T. Parsa 《Journal of clinical neuroscience》2013,20(2):281-286
Esthesioneuroblastoma (EN) is a rare sinonasal tumor with varied aggressiveness and potential for intracranial invasion. EN is staged anatomically with radiographic evaluation using the Kadish staging system (stages A, B, and C) and histologically by using Hyam’s criteria (grades 1–4). Here we show that despite radiographic evidence of aggressive features, the prognosis of patients with Kadish stage C EN is best predicted by tumor histology using Hyam’s criteria. We retrospectively analyzed patients with EN with Kadish stage C who were evaluated and treated at our institution between 1995 and 2009. Clinical information was collected using patient medical records, imaging, and review of pathological specimens. Twenty patients with Kadish stage C EN were identified with mean age of 51 years (31–70 years) with a median follow-up of 41.4 months (1.3–175 months). Upon pathological review, 44.4% of patients had low-grade (1/2) and 55.6% had high-grade (3/4) histology. About 37.5% of patients with low-grade EN had undergone gross total resection (GTR) and the remaining 62.5% had GTR and adjuvant radiation, whereas 50% of patients with high-grade ER had undergone GTR, 20% had undergone GTR and adjuvant radiation, and 30% had been treated with a subtotal resection (STR) and adjuvant radiation. The 5-year and 10-year survival in patients with low-grade EN was 86% in comparison to 56% and 28% with high-grade EN, respectively. In patients with low-grade EN, the 2-year progression free survival (PFS) was 86% and the 5-year PFS was 65% in comparison to 73% and 49% in patients with high-grade EN, respectively. The patient’s tumor histology (Hyam’s criteria) appeared to be the best way of predicting the prognosis and for selecting patients for adjuvant radiotherapy. 相似文献

Central neurocytomas are classically considered as a rare, intraventricular benign tumours with neuronal differentiation derived from precursor cells of subventricular matrix. However some patients with neoplasms with histologic atypia and elevated proliferation potential may have a poor outcome. Treatment of choice is complete surgical excision. Adjuvant therapy is reserved for patients with residual or recurrent lesions including reoperation, radiotherapy or chemotherapy. We review our experience with the treatment of this neoplasm. Five patients with an intraventricular mass studied with magnetic resonance imaging underwent craniotomy for tumour resection. All cases were reviewed retrospectively. Histopathological analysis confirmed central neurocytoma in all cases. Proliferation index was assessed by Ki-67 immunohistochemistry. Complete radiological tumor resection through transcortical approach was achieved in all except one patient. In this case adjuvant therapy with radiosurgery was given with important reduction in tumor size. All the tumours had a proliferation index below 2% except one with 5%. Follow-up in four patients ranged from 12 to 36 months. There were no tumour recurrences in this period. Complete surgical excision of central neurocytoma provides better local control and survival compared with other treatments. Radiosurgery as adjuvant therapy in incomplete resections may eliminate the need of reoperation and avoid long-term side effects from conventional radiotherapy. 相似文献

PURPOSE: Central neurocytoma is a rare intraventricular brain tumor that affects young adults and presents with increased intracranial pressure secondary to obstructive hydrocephalus. Typically, it has a favorable prognosis after adequate surgical intervention, but in some cases the clinical course is more aggressive. In this report, we describe the diagnosis and treatment of central neurocytoma in a series of patients at our institution. PATIENTS AND METHODS: Our series of nine patients (M:F=2:7, mean age, 28.2 years) with ventricular tumors showed typical radiological, histologic and immunohistochemical features of central neurocytoma. Most patients received craniotomy with removal of the tumor through transcallosal or transcortical approach. The surgical and histopathologic data of these patients were reviewed and analyzed. RESULTS: The prognosis is generally favorable. Although most patients were alive and well at the last follow-up, two developed recurrence. Typical histologic features of recurrent neurocytoma include high proliferative activity (MIB-1 labeling index: 2.0-6.8%), prominent vascular proliferation and remarkable synaptophysin expression. Two patients (non-recurrent) died during follow-up due to sepsis or central failure. The MIB-1 labeling indices were as high as 2.2-5.4% for these two patients. CONCLUSION: Although central neurocytoma is generally a benign neoplasm, some variant forms of recurrence are also present. Complete resection provides favorable long-term prognosis in most cases. Recurrent tumors are often local and the patients seem to recover well after a second resection followed by radiotherapy. Histologic features such as tumor proliferation (MIB-1 labeling index), vascular proliferation, and synaptophysin expression are often prominent in the recurrent tumor. We recommend that these histologic features be considered for tumor recurrence during treatment and follow-up of these patients. 相似文献

Intracranial hemangiopericytoma (HPC) is an aggressive meningothelial neoplasm. A particularly challenging aspect of management of patients with HPC is optimizing treatment for recurrence, progression, and extracranial metastasis. Here we describe a modern cohort of patients with recurrent HPC to better understand treatment strategies that may improve outcome. Patients managed at UCSF for recurrent intracranial HPC were compiled into a single database based on a retrospective review of patient records, including operative, radiologic, and clinic reports. Cox regression was performed to determine factors that independently predicted treatment outcomes. At UCSF, 14 patients with available treatment and follow-up data were seen for management of HPC recurrence. Eight patients underwent repeat surgical resection, of whom four received adjuvant external beam radiotherapy (EBRT), one received additional Gamma Knife radiosurgery (GKS), and one received brachytherapy. Radiosurgical intervention alone was utilized for recurrence in six patients, with four receiving GKS and two receiving CyberKnife. Nine patients suffered a second recurrence at a median time of 3.5 years following reintervention. Nine patients died following reintervention, with a median survival of 7.9 years following intervention for recurrence. In univariate analysis, factors associated with increased time to second recurrence included non-posterior fossa location (log rank, p < 0.05) and surgical resection with adjuvant EBRT (log rank, p < 0.05). The addition of adjuvant EBRT to surgical resection similarly extended overall survival compared to surgical resection alone (log rank, p < 0.05). GKS was associated with earlier second recurrence compared to surgically based strategies (log rank, p < 0.05). We conclude that when combined with surgical resection, EBRT appears promising in the extension of second recurrence-free survival and overall survival. This multimodality approach also appears to outperform GKS in extending time to second recurrence. Accordingly, when safe and feasible, surgical resection of recurrent HPC with adjuvant EBRT should be the first steps in management. 相似文献

Brain metastases are the most common intracranial tumors. Overall, the only accepted prognostic factors are patient age and performance status. However, several other factors are considered before surgery. We performed a retrospective analysis of 309 patients who underwent surgical resection of newly diagnosed brain metastases between 1994 and 2004. Univariate survival analysis revealed age, performance status, extracranial metastases, complete resection, radiotherapy and re-craniotomy as prognostic indicators. Multivariate analysis determined that patient age, performance status, extracranial metastases, radiotherapy and re-craniotomy are independent factors of prolonged survival. We statistically estimated the age threshold separating patients with favorable outcomes from those with unfavorable prognoses. Using the Kaplan-Meier analysis this threshold can be set at 65 years. Multivariate analysis of patients >65 years revealed the presence of co-morbidities, the number of brain metastases, post-operative performance status and radiotherapy as independent prognostic factors. 相似文献

Despite the relatively low-grade of most central neurocytomas (CN), evidence suggests the existence of an aggressive subset with a propensity for recurrence. Recent studies have found the MIB-1 labeling index to be a prognostic indicator in CN. Here we review our experience with CN to analyze the relationships between extent of resection, adjuvant therapy, tumor histology, and clinical outcomes based on aggressive histology, as defined by MIB-1 labeling. A retrospective review was performed on histologically proven CN surgically resected from 1993 to 2009 at the University of California at San Francisco. Recurrence rates were analyzed using the Kaplan–Meier method with respect to MIB-1 labeling and extent of resection. All MIB-1 labeling indices were analyzed. A total of 18 patients were identified with a mean age of 30 years (range 17–58 years) and median follow-up of 40 months (5–173 months). The treatments were: gross total resection (GTR) alone (17% of patients), subtotal resection (STR) alone (50% of patients), STR plus radiotherapy (XRT: external beam or stereotactic radiosurgery: 28% of patients), or STR plus chemotherapy (5% of patients). The extent of resection and a MIB-1 labeling index >4% was predictive of recurrence (p < 0.01). In the 33% of the patients in whom the tumor recurred, all had STR with MIB-1 labeling >4% with median time to recurrence of 23.5 months. The 2-year and 4-year recurrence rates in patients with MIB-1 labeling >4% were 50% and 75% respectively. No patient with a MIB-1 labeling index <4% who received STR alone had a recurrence. Thus, in patients with CN who were treated with STR, histology demonstrating a MIB-1 labeling index >4% can be a clinically useful prognostic indicator and can help guide adjuvant treatment. 相似文献

Spinal ependymomas are rare tumours, with total resection favoured where possible. Several case series assessing the outcome following neurosurgical treatment for spinal ependymoma advocate the usage of adjuvant radiotherapy in cases of subtotal resection, or in unencapsulated tumours. We assessed the outcome of 61 consecutive cases of spinal ependymoma in a single centre over a 20 year period using a variety of outcome measures. Sex distribution was equal, with a mean age at surgery of 43.6 years (range 5–76 years). Overall, most tumours occurred in the lumbosacral region (70.5%), with fewer in the thoracic (27.9%) and cervical regions (18.0%). Myxopapillary features were seen in 41.0% of tumours, and were more common when occurring in the lumbar region (51.2%). Gross total resection was achieved in 52.5%, subtotal resection in 37.7% and biopsy alone in 9.8% of patients and 31.1% received adjuvant radiotherapy. Two-thirds of patients achieved an excellent post-operative neurological outcome (Frankel grade E). Tumour recurrence was rare. Gross total resection and good preoperative neurological condition were most strongly predictive of good outcome. Post-operative radiotherapy did not seem to confer survival benefit in this case series, even in cases of incomplete resection, leading us to question its utility for all cases of spinal cord ependymoma. 相似文献

Temozolomide-based chemotherapy represents an incremental improvement in the treatment of patients with high-grade gliomas. Notwithstanding a survival benefit in a subset of patients with high-grade gliomas, temozolomide (TMZ; Temodar?, Schering-Plough Pharmaceuticals, NJ, USA) is the primarily palliative treatment for the vast majority of patients. Indeed, for patients with newly diagnosed glioblastoma, the median increase in survival for treatment with TMZ and radiotherapy is only 2.5 months compared with radiotherapy alone. Additionally, recent studies suggest that 60-75% of patients with glioblastoma derive no benefit from treatment with TMZ. For the treatment of recurrent anaplastic gliomas, more than 50% of patients fail TMZ treatment with cancer progression at 6 months, demonstrating that TMZ is only a modestly effective chemotherapy. In addition, 15-20% of patients treated with TMZ develop clinically significant toxicity, which can leave further treatment unsafe. Despite the availability of TMZ, there is still a substantial need for a chemotherapeutic agent that is more effective and safe. In fact, there still remains a significant unmet need for more effective treatments of high-grade gliomas (improved palliation or cure), whether that treatment be by surgery, radiotherapy, chemotherapy or any yet to be developed type of treatment, such as 'targeted therapies'. 相似文献

Glioneuronal tumors are common neoplasms among the cerebral hemisphere during childhood. They consist of several histological types, of which gangliogliomas (GGs) and dysembryoplastic neuroepithelial tumors (DNTs) are most common and often present with seizures. A great majority of glioneuronal tumors are benign. However, there are conflict reports regarding postoperative tumor recurrence rates and seizure control. The authors analyzed and compared these tumors for their locations and histology and the tumor and seizure control following resection.Methods
The authors conducted a retrospective analysis of patients with pediatric glioneuronal tumors in the cerebral hemisphere. All histology reports and neuroimaging are reviewed. Seizure group and non-seizure group were compared with their tumor types and locations. The extent of tumor resections were divided into gross total resection (GTR) and subtotal resection (STR). Postoperative tumor recurrence-free survival (RFS) and seizure-free survival for patients who had the initial surgery done at our institution were calculated using Kaplan-Meier method.Results
There were 90 glioneuronal tumors including 58 GGs, 22 DNTs, 3 papillary glioneuronal tumor, 3 desmoplastic infantile gangliogliomas, 3 anaplastic GGs, and 1 central neurocytoma. Seventy-one patients (seizure group) presented with seizures. The temporal lobe is the most common location, 50 % in this series. GTR was attained in 79 patients and STR in 11. All of the patients with GTR had lesionectomy, and only six of them had extended corticectomy or partial lobectomy. Postoperative seizure outcome showed that 64 (90 %) of seizure group had Engel’s class I, but five patients subsequently developed recurrent seizures. Patients with DNTs had a higher seizure recurrence rate. Tumor RFS was 87 % at 5 years and 75.5 % at 10 years. There are no significant difference in tumor recurrences between GGs and DNTs (p?=?0.876). Comparison between GRT (67) and STR (9) showed that in spite of the better 5-year tumor RFSs among GRT group (94 %) than STR group (66 %), the 10-year RFSs showed no significant difference between GRT and STR groups (p?=?0.719). Recurrent seizures are often related to recurrent tumor.Conclusion
Lesionectomy alone often provides a high-rate seizure freedom. GGs and DNTs are benign tumor, but recurrences of GGs and DNTs are not uncommon. They may show late recurrences in spite of GTR. These patients need longer follow-up for 10 years. Recurrent seizures are often related to a tumor recurrence.16.
Rapid tumor growth with glial differentiation of central neurocytoma after stereotactic radiosurgery
Although stereotactic radiosurgery (SRS) is effective for central neurocytoma (CN), the long-term outcome of SRS remains unclear. We present a case of recurrent CN that was diagnosed 10 years after surgical resection and consecutive stereotactic radiotherapy. The patient was treated with SRS for the recurrent tumor, but underwent two-staged surgery once again due to rapid tumor growth. Histological features of the recurrent tumor were consistent with the diagnosis of CN. However, an increased Ki-67 proliferation index (3.4%), aberrant angiogenesis and glial differentiation of the tumor cells were observed, which were not identified in the initial CN. In addition, vascular endothelial growth factor (VEGF) and VEGF receptor were highly expressed in the recurrent tumor cells, as well as in the vascular endothelial cells. Our case suggests that malignant transition with aberrant angiogenesis and glial differentiation may be attributable to SRS. 相似文献

Recent studies suggest that subtotal resection (STR) followed by adjuvant radiation therapy is an appealing alternative to gross total resection (GTR) for craniopharyngioma, as STR provides similar tumor control without the associated endocrinological and behavioral morbidity. We have examined the impact of maximal safe resection on the clinical outcome of patients with craniopharyngioma. A total of 90 patients underwent surgical resection of craniopharyngioma at a single institution between January 1995 and April 2009. Sixty-one patients underwent GTR alone, four underwent GTR followed by adjuvant radiotherapy, 15 underwent STR alone, and 10 underwent partial removal followed by adjuvant radiotherapy. We analyzed and compared the clinical and endocrinological outcomes and radiological follow-up data of these patients. During the follow-up period, tumor recurrence following the initial resection occurred in 36 of 90 patients (40%). The repeat resection rate was higher in the STR group than the GTR group. Recurrence occurred in 20 of 61 patients (32.8%) from the GTR alone group, in 11 of 15 patients (73.3%) from the STR alone group, and in five of 10 (50%) patients from the STR with adjuvant radiation, such as radiotherapy or stereotactic radiosurgery, group (p=0.030). Maximal safe resection of craniopharyngioma leads to excellent local control. STR with adjuvant radiation therapy does not assure preservation of endocrine function, although it provides better local control than STR alone. 相似文献
