Object. Primary chondrosarcoma of the spine is extremely rare. During the last 43 years only 21 patients with this disease were registered at The University of Texas M. D. Anderson Cancer Center. The purpose of this study was to examine the demographic characteristics, treatments, and outcomes of this set of patients. Methods. Medical records for 21 patients were reviewed. Age, sex, race, clinical presentation, tumor histology, tumor location in the spinal column, treatments, surgical details, and response to treatment were recorded. Surgical procedures were categorized as either gross-total resection or subtotal excision of tumor. Neurological function was assessed using Frankel's functional classification. Time to recurrence and survival analyses were performed using the Kaplan—Meier method. The median age of patients was 51 years, with fairly equal gender representation. Eighteen patients underwent at least one surgical procedure for a total of 28 surgical procedures: seven radical resections and 21 subtotal excisions. Radiation therapy was used in conjunction with 10 of the 28 surgical procedures. The median Kaplan—Meier estimate of overall survival for the entire group was 6 years (range 6 months–17 years). Tumors recurred after 18 of the 28 procedures. Kaplan—Meier analysis revealed a statistically significant difference in the per-procedure disease-free interval after gross-total resection relative to subtotal excision (exact log rank 3.39; p = 0.04). The addition of radiation therapy prolonged the median disease-free interval from 16 to 44 months, although this was not statistically significant (exact log rank 2.63; p = 0.16). Conclusions. Our results suggest that gross-total resection of the chondrosarcoma provides the best chance for prolonging the disease-free interval in patients. Subtotal excision should be avoided whenever possible. Addition of radiation therapy does not appear to lengthen significantly the disease-free interval in this patient population.

Object. The goals of this study were to analyze outcomes in patients with posterior fossa ependymomas, determine whether gross-total resection (GTR) alone is appropriate treatment, and evaluate the role of radiation therapy. Methods. All patients with newly diagnosed intracranial ependymomas treated at Barrow Neurological Institute between 1983 and 2002 were identified. Those with supratentorial primary lesions, subependymomas, or neuraxis dissemination were excluded. Forty-five patients met the criteria for the study. Gross-total resection was accomplished in 32 patients (71%) and subtotal resection (STR) in 13 (29%). Radiation therapy was given to 25 patients: 13 following GTR and 12 after STR. The radiation fields were craniospinal followed by a posterior fossa boost in six patients and posterior fossa or local only in the remaining patients. With a median follow-up period of 66 months, the median duration of local control was 73.5 months with GTR alone, but has not yet been reached for patients with both GTR and radiotherapy (p = 0.020). The median duration of local control following STR and radiotherapy was 79.6 months. The 10-year actuarial local control rate was 100% for patients who underwent GTR and radiotherapy, 50% for those who underwent GTR alone, and 36% for those who underwent both STR and radiotherapy, representing significant differences between the GTR-plus-radiotherapy and GTR-alone cohorts (p = 0.018), and between the GTR-plus-radiotherapy and the STR-plus-radiotherapy group (p = 0.003). There was no significant difference in the 10-year actuarial local control rate between the GTR-alone and STR-plus-radiotherapy cohorts (p = 0.370). The 10-year overall survival was numerically superior in patients who underwent both GTR and radiotherapy: 83% compared with 67% in those who underwent GTR alone and 43% in those who underwent both STR and radiotherapy. These differences did not achieve statistical significance. Univariate analyses revealed that radiotherapy, tumor grade, and extent of resection were significant predictors of local control. Conclusions. Gross-total resection should be the intent of surgery when it can be accomplished with an acceptable degree of morbidity. Even after GTR has been confirmed with postoperative imaging, however, adjuvant radiotherapy significantly improves local control. The authors currently recommend the use of postoperative radiotherapy, regardless of whether the resection is gross total or subtotal.

Background: Radio-frequency ablation (RFA) and Stereotactic Body Radiation Therapy (SBRT) are two emerging therapies for lung metastases. Introduction: We performed a literature review to evaluate outcomes and complications of these procedures in patients with lung metastases from soft tissue sarcoma (STS). Method: After selection, seven studies were included for each treatment encompassing a total of 424 patients: 218 in the SBRT group and 206 in the RFA group. Results: The mean age ranged from 47.9 to 64 years in the SBRT group and from 48 to 62.7 years in the RFA group. The most common histologic subtype was, in both groups, leiomyosarcoma. : In the SBRT group, median overall survival ranged from 25.2 to 69 months and median disease-free interval from 8.4 to 45 months. Two out of seven studies reported G3 and one G3 toxicity, respectively. In RFA patients, overall survival ranged from 15 to 50 months. The most frequent complication was pneumothorax. : Local control showed high percentage for both procedures. Conclusion: SBRT is recommended in patients unsuitable to surgery, in synchronous bilateral pulmonary metastases, in case of deep lesions and in patients receiving high-risk systemic therapies. RFA is indicated in case of a long disease-free interval, in oligometastatic disease, when only the lung is involved, in small size lesions far from large vessels. : Further large randomized studies are necessary to establish whether these treatments may also represent a reliable alternative to surgery.

Absztrakt A szerzők az utóbbi 5 évben operált colorectalis eredetű tüdő metastasisok sebészi kezelésének retrospektiv értékeléséről számolnak be. Megvizsgálják a colorectalis tumorok pulmonalis áttétképzésének sajátságait és a túlélést befolyásoló prognosztikus faktorokat, valamint összevetik saját tapasztalataikat a nemzetközi szakirodalommal. 2001 és 2005 között 33 betegen 37 műtétet végeztek. A betegek között 14 nő és 19 férfi volt, átlagéletkoruk 61.3 év (49–76 év). A műtéti típust, a betegségmentes időszakot (Disease Free Interval, DFI), az oldaliságot, az áttétszámot, a lokalizációt, a nyirokcsomó érintettséget, valamint a máj metastasisok jelenlétét vizsgálták lehetséges prognosztikus faktorként. A 37 műtét közül 20 szoliter, 17 multiplex elváltozás miatt történt. 25 esetben atypusos resectiot, 12 lobectomiát (melyből 1 sleeve resectio) és 1 esetben pulmonectomiát végeztek. 18 betegnél jobb, 9 betegnél bal oldali, és 6 betegnél kétoldali folyamatot operáltak. Hat páciensnél synchron ill. metachron hepaticus metastasis miatt máj resectio is történt. A túlélést Kaplan–Meier módszerrel, a tüdő resectio időpontjától kezdődően számították. Az átlagos betegségmentes időszak 27.6 hónap volt. A teljes beteganyagra vonatkoztatott átlagos túlélés 28 hónap volt. Ha csak tüdő metastasis jelentkezett, a 3 éves túlélés 52% volt. A colorectalis tumor utáni tüdőáttétek resectioja kedvezően befolyásolja a túlélést. A várakozással szemben, az operált szoliter ill. multiplex metastasisok (max. 7 metastasis) túlélési eredményei között nem találtak szignifikáns eltérést. A vizsgált beteganyagban a regionális nyirokcsomó áttétes betegek túlélése átlagosan 12 hónappal rövidebb, mint a nyirokcsomó negatív eseteké. A relatíve alacsony esetszám miatt a statisztikai következtetés korlátozott. A szakirodalom megfigyeléseivel ellentétben nem észlelték, hogy a 24 hónapnál hosszabb DFI után szignifikánsan hosszabb lenne a túlélés. A synchron ill. metachron májáttéttel rendelkező 6 beteg átlagos túlélése 10 hónappal rövidebb a többi betegénél, de az alacsony esetszám miatt ez nem bizonyító erejű. A vizsgált többi faktornak (lokalizáció, áttétszám, oldaliság) analízisük szerint nincs prediktiv értéke.

Background and Objective:  The complex insular anatomy and its proximity to eloquent areas make this area almost inaccessible for safe surgical resection of Glioma. Aim of our study is to determine outcome assessment after surgical resection. Materials & Methods:  This was a retrospective analysis of 59 patients over a period of 5 years from July 2013 till June 2018. All patients of insular Glioma were included in our study irrespective of age and sex. Degree of surgical resection, Post-operative neurological deficits and complications were assessed. They were followed in the outpatient department at 3, 6 and 12 months. Results:  Total 59 patients were included 38 (64.40%) male and 21 (35.59%) females. 36 (61%) patients had right sided insular Glioma and 23 (38.98%) have left sided. Seizures were main presentation in 46(77.96%) patients. Trans-sylvian route adopted in 34 (57.6%) patients followed by transcortical route. Near total Resection was Possible in 30 (50.84%) patients and partial in 29 (49.15%) patients. Focal neurological deficits the motor weakness & dysphasia were main post-operative complications in 18 (30.5%) patients. Three (5.08%) patients died. In all grade II and grade III Gliomas no increase in size was discovered on MRI Brain at 6 and 12 months. Conclusion:  Maximum safe resection of insular Glioma with acceptable morbidity is possible with improved overall survival and disease free interval.

Object. The indications, operative findings, and outcomes of vestibular schwannoma microsurgery are controversial when it is performed after stereotactic radiosurgery. To address these issues, the authors reviewed the experience at two academic medical centers. Methods. During a 10-year interval, 452 patients with unilateral vestibular schwannomas underwent gamma knife radiosurgery. Thirteen patients (2.9%) underwent delayed microsurgery at a median of 27 months (range 7–72 months) after they had undergone radiosurgery. Six of the 13 patients had undergone one or more microsurgical procedures before they underwent radiosurgery. The indications for surgery were tumor enlargement with stable symptoms in five patients, tumor enlargement with new or increased symptoms in five patients, and increased symptoms without evidence of tumor growth in three patients. Gross-total resection was achieved in seven patients and near-gross-total resection in four patients. The surgery was described as more difficult than that typically performed for schwannoma in eight patients, no different in four patients, and easier in one patient. At the last follow-up evaluation, three patients had normal or near-normal facial function, three patients had moderate facial dysfunction, and seven had facial palsies. Three patients were incapable of caring for themselves, and one patient died of progression of a malignant triton tumor. Conclusions. Failed radiosurgery in cases of vestibular schwannoma was rare. No clear relationship was demonstrated between the use of radiosurgery and the subsequent ease or difficulty of delayed microsurgery. Because some patients have temporary enlargement of their tumor after radiosurgery, the need for surgical resection after radiosurgery should be reviewed with the neurosurgeon who performed the radiosurgery and should be delayed until sustained tumor growth is confirmed. A subtotal tumor resection should be considered for patients who require surgical resection of their tumor after vestibular schwannoma radiosurgery.

✓ Between 1975 and 1989, 108 children with newly diagnosed medulloblastoma/primitive neuroectodermal tumor (MB/PNET) of the posterior fossa were treated at the authors' institution. The patients were managed uniformly, and treatment included aggressive surgical resections, postoperative staging evaluations for extent of disease, and craniospinal radiation therapy with a local boost. Beginning in 1983, children with MB/PNET were prospectively assigned to risk groups; those with “standard-risk” MB/PNET were treated with radiation therapy alone, while those in the “poor-risk” group received similar radiation therapy plus adjuvant chemotherapy with 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU), vineristine, and cisplatin. The 5-year actuarial disease-free survival rate for all patients treated between 1975 and 1982 was 68%, and 73% when patients who died within 2 weeks after operation were excluded. This survival rate was statistically better for patients treated after 1982 (82%) compared to those treated between 1975 and 1982 (49%) (p < 0.004). There was no difference in disease-free survival rates over time for children with standard-risk factors; however, there was a significant difference in the 5-year survival rate for poor-risk patients treated prior to 1982 (35%) compared to those treated later (87%) (p < 0.001). For the group as a whole, a younger age at diagnosis correlated with a poorer survival rate; however, this relationship between age and outcome was significant only for children treated before 1983 (p < 0.001). These results demonstrated an encouraging survival rate for children with MB/PNET, especially those treated with aggressive surgical resection followed by both radiation therapy and chemotherapy. The results strongly suggest that chemotherapy has a role for some, and possibly all, children with MB/PNET.

Object. Progression of infiltrative low-grade gliomas (LGGs) has been reported previously. The limitations of such studies include diverse histological grading systems, intervening therapy, and the lack of histological confirmation of malignant tumor progression. The aim of this study was to determine tumor progression in adult patients with an initial diagnosis of infiltrative LGG who subsequently underwent a repeated operation, but no other intervening therapy. The authors examined factors that may be associated with tumor progression. Methods. The authors retrospectively reviewed a database of 300 patients with the initial diagnosis of LGG and who had been treated at their institution between 1990 and 2000. One hundred four of these patients had undergone a second surgery. Patients with infiltrative LGGs who had undergone two surgical procedures at least 3 months apart without intervening therapy were selected; the authors identified 40 patients who fit these criteria. Clinical, neuroimaging, and pathological data were centrally reviewed. There were 29 men and 11 women in the study, whose median age was 35.5 years (range 23–48 years). At the time of the second surgery, 50% of patients had experienced tumor progression. Patients whose tumors had progressed had a longer median time to repeated operation (49 compared with 22.5 months). Patients who had undergone gross-total resection, as demonstrated on postoperative magnetic resonance images, had a median time to repeated operation of 49 compared with 25 and 24 months in patients who underwent subtotal resection and biopsy, respectively (p = 0.02). The extent of resection did not influence the likelihood of tumor progression (p > 0.3). Conclusions. Fifty percent of patients with initially diagnosed infiltrative LGGs had tumor progression at the time of a repeated operation. A gross-total resection was associated with an increased time to repeated surgery. There was no statistically significant effect of gross-total resection as a predictor of tumor progression.

Object. The authors describe the treatment and results of thoracoscopic resection performed in patients with neurogenic tumors. Methods. Seven patients with large intrathoracic paraspinal neurogenic tumors underwent a thoracoscopic procedure to achieve gross-total resection. All tumors were entirely intrathoracic and treated thoracoscopically except in one patient whose tumor had an intraspinal extension. Gross-total resection was achieved in all cases. Postoperatively, one patient developed Horner syndrome. The only other complication, transient intercostal neuralgia, resolved in all patients. Clinical examination and magnetic resonance imaging follow-up examination in all patients demonstrated no evidence of recurrent disease (mean follow up 12.5 months). Conclusions. Endoscopic transthoracic approaches can reduce approach-related soft-tissue morbidity and facilitate a patient's recovery by preserving the normal tissues of the chest wall, by avoiding rib retraction and muscle transection, and by reducing postoperative pain.

✓✓ The authors describe the case of a 38-year-old man with progressive headache and blurred vision related to a hemangiopericytoma located exclusively in the confluence of sinuses (CoS) and in the transverse sinuses bilaterally. They believe this is the first report in which a hemangiopericytoma of the dural sinuses has been described without any intradural component. Although the diagnosis was not suspected preoperatively, a gross-total resection of the tumor with restoration of sinus patency was achieved to relieve the symptoms. This diagnosis should be included in the preoperative differential diagnosis of a tumor of the CoS. Successful resection can be achieved in these cases.

✓ The authors report the case of a 36-year-old woman who underwent gross total resection of a right cerebellar pleomorphic xanthoastrocytoma with atypical features. She had undergone surgery 16 years previously for what was thought to be a right frontal glioblastoma multiforme. In retrospect, based on the histopathology and the clinical course, both lesions were considered to represent atypical variants of pleomorphic xanthoastrocytoma. This report examines the histological and clinical characteristics of this posterior fossa lesion, which exhibited histologically malignant features but has run a relatively indolent course.
