Individualized Cerebral Artery Protection Strategies for the Surgical Treatment of Parasellar Meningiomas on the Basis of Preoperative Imaging

ObjectiveParasellar meningiomas (PMs) represent a cohort of skull base tumors that are localized in the parasellar region. PMs tend to compress, encase, or even invade the cerebral arteries and their perforating branches. The surgical resection of PMs without damaging neurovascular structures is challenging. This study aimed to analyze functional outcomes in a series of patients who underwent surgery with individualized cerebral artery protection strategies based on preoperative imaging.MethodsA retrospective review was performed on a single surgeon’s experience of the microsurgical removal of PMs in 163 patients between January 2012 and March 2020. Individualized approaches with a bidirectional dissection strategy were used. Cerebral artery invasion classification, neurological outcomes, MRC Scale for muscle strength, and Karnofsky performance scale were used to assess tumor vascular invasion, functional outcome, and patient quality-of-life outcomes, respectively.ResultsTotal resection (Simpson grade I or II) was achieved in 114 patients (69.9%) in our study. A total of 44.7% of patients had improved vision at consecutive follow-ups, 51.1% were stable, and 3.8% deteriorated. Improvements in cranial nerves III, IV, and VI were observed in 41.1%, 36.2%, and 44.8% of patients, respectively. The mean follow-up time was (38.8 ± 27.9) months, and the KPS at the last follow-up was 89.6 ± 8.5. Recurrence was observed in eight patients (13.8%) with cavernous sinus meningiomas, and the recurrence rates in anterior clinoid meningiomas and medial sphenoid wing meningiomas were 3.8% and 2.8%, respectively.ConclusionsPreoperative imaging is important in the selection of surgical approaches. Maximum tumor resection and cerebral artery protection can be achieved concurrently by utilizing the bidirectional dissection technique. Individualized cerebral artery protection strategies provide great utility in improving a patient’s quality of life.

High Morbidity

Vulvar cancer represents 4% to 5% of Low Genital Tract Tumors (LGTT) and 1% of all cancers in women. Treatment depends on stage, and when possible surgery is preferable. Advanced cancers require large resections (with needs grafts and-or rotating flaps), radio and/or chemotherapy, all of which can lead to high morbidity and quality of life impairment. To minimize these effects, in 1994, we developed a cryosurgery prospective protocol to manage vulvar cancer in patients with comorbid conditions.Patients and Methods: Between 1994 and 2019 we treated n=41 patients: FIGO stages I: n=2 (4.88%) II: n=9 (21.95%), III: n=28 (68.29%), IV: n=2 (4.88%). Median age 64.3 (28 to 90 years old), and 70% were 70 years old or older, 59% had severe comorbidities (diabetes, autoimmune diseases, immunosuppressive user).Cryosurgery Protocol:Firstly, tumor resection, hemostasis, and 2 rapid freezing- slow thawing cycles with Liquid Nitrogen (LN) spray. The cycles should include the logde and a 1.5 cm safety margin. After complete healing (between 45 and 95 days after cryosurgery), nodes are treated according to FIGO stages. Result:All patients after the effects of the anesthesia were able to urinate spontaneously, walk, had minimal analgesic requirements, with good postoperative. The patients remained in the hospital for one or two days, and with rare exceptions, were discharged the following day with controls twice a week at the hospital. None of the patients required flaps or grafts to repair the treated areas. After complete healing they maintained the vulvar sensitivity and considerably improved their quality of life. Some of them, who had a partner, were able to resume their sexual intercourse.Mean follow-up: 55.39 (3 months to 258 months). Five patients had local recurrences between 12 and 72 months after treatment, and were controlled with a new cryosurgery. Six patients had HPV related lesions located in other areas of the lower genital tract, which were also controlled with cryosurgery. Twenty five of them died 19 due to an unrelated cause of death, and 6 due to disease progression in the nodes without vulvar recurrence, 9 patients survived and were free of disease with a mean follow-up of 53 months. Seven patients, after a disease free follow up of 17.2 months, weren ́t able to be controlled, as they lived more than 400 km way from the hospital. Local control was achieved in all patients.Comments: Cryosurgery can be done after any previous treatment, and can be repeated to control recurrences.Conclusion: Given the simplicity of the technique, its low cost, the possibility of being used in patients with multiple co-morbidities, the absence of major complications, and the anatomical and functional results obtained, we believe that cryosurgery can be considered among the best options to control of vulvar cancer, even large or advanced cases, in elderly patients and-or with severe comorbidities.

Abstract OBJECTIVE: Nonvestibular schwannomas are uncommon tumors of the brain. Trigeminal nerve schwannomas are the most common of this group, followed by glossopharyngeal, vagal, facial, accessory, hypoglossal, oculomotor, trochlear, and abducens nerve schwannomas, in descending order of frequency. We present a series of nonvestibular schwannomas that were surgically treated during a 7-year period. METHODS: Forty-six patients with schwannomas of Cranial Nerves V (26 cases), VII (7 cases), IX, X, and XI (9 cases), XII (3 cases), and III (1 case) were microsurgically treated by the senior author (LNS) during a 7-year period, from 1993 to 2000. The clinical presentations, operative approaches, complications, and results were studied. RESULTS: Forty-five patients underwent gross total tumor resection in the first operation. One patient who had undergone subtotal tumor resection in the initial operation experienced a large recurrence after 4 years, and gross total tumor resection was achieved in the second operation. There were no postoperative deaths. Postoperative morbidity consisted of cerebrospinal fluid leaks for 5 patients (3 patients required a second operation to repair the leak, and 2 patients responded to lumbar drain placement), meningitis for 3 patients (2 cases were aseptic and 1 involved bacterial meningitis, which resolved with antibiotic therapy), vasospasm requiring angioplasty for 1 patient, temporary hemiparesis for 2 patients (who experienced good recoveries), and permanent hemiparesis for 1 patient. New cranial nerve deficits were observed for 24% of patients but were usually partial. The mean follow-up period was 33.3 months (range, 0.2–93 mo). No patient experienced tumor recurrence after complete tumor removal. The patient who experienced regrowth of the tumor did not exhibit recurrence after the second operation. The Karnofsky Performance Scale scores at the latest follow-up examination were 80 or more for 45 patients (98%) and 70 for 1 patient. CONCLUSION: Nonvestibular schwannomas can be treated via microsurgical excision, with excellent functional results. Recurrence is rare after total tumor excision, although much longer follow-up monitoring is required.

OBJECTIVEPineal region tumors are a rare and heterogeneous group of lesions. The optimal therapeutic approach is currently a topic of controversy, particularly in light of the potential operative risks and complications. The potential beneficial effects of surgery have already been described, but information about neurological outcome and, in particular, health-related quality of life (HRQOL) is still lacking in the literature. The aim of this study was to assess the therapeutic effect of resection of pineal region lesions, emphasizing grade of tumor resection, neurological outcome, quality of life, and the necessity of additional shunt procedures.METHODSThe authors performed a prospective study of HRQOL in 32 patients who had undergone surgical treatment of lesions in the pineal region (20 tumors and 12 cysts) between 2008 and 2014. All patients had at least 6 months of follow-up, with reexamination including standardized neurological assessment, an evaluation of dependency using the modified Rankin Scale, and an evaluation of HRQOL. The authors retrospectively examined patient charts and collected information regarding imaging studies, neurological status prior to surgery, surgical strategies used, any complications, and histological diagnoses.RESULTSIn this study, there was no surgery-associated mortality or major morbidity. Permanent minor morbidity was reported for 4 patients (13%). Comparing pre- and postoperative neurological symptoms, 75% of tumor patients had either complete resolution or improvement of preoperative symptoms; symptoms were unchanged in 10% of tumor patients and deteriorated in 15%. In patients with pineal cysts, long-term follow-up showed that 42% of patients were free of any symptoms and 58% experienced improvement of their preoperative symptoms. These outcomes were also reflected in the modified Rankin Scale scores, which demonstrated significant improvement following resection of pineal region lesions. Furthermore, significant improvements in HRQOL scores occurred in global health status, in all functional scales, and in pain, nausea and vomiting, fatigue, and insomnia (p < 0.0001). Moreover, a significant reduction in the necessity for permanent shunt procedures was observed after gross-total tumor resection compared with subtotal resection (p = 0.035) of pineal cysts.CONCLUSIONSDespite potential risks, (radical) surgery is a highly effective and safe treatment option for pineal region lesions and should be considered for the majority of patients.

Object No clear treatment guidelines for pediatric craniopharyngiomas exist. The authors developed a decision analytical model to evaluate outcomes of 4 surgical approaches for craniopharyngiomas in children, including attempted gross-total resection (GTR), planned subtotal removal plus radiotherapy, biopsy plus radiotherapy, and endoscopic resections of all kinds. Methods Pooled data, including the authors' own experience, were used to create evidence tables, from which incidence, relative risks, and summary outcomes in quality-adjusted life years (QALYs) were calculated for the 4 management strategies. Results Quality-adjusted life years at the 5-year follow-up were 2.3 ± 0.1 for attempted GTR, 2.9 ± 0.2 for planned subtotal removal plus radiotherapy, 3.9 ± 0.2 for biopsy plus radiotherapy, and 3.7 ± 0.2 for endoscopic resection (F = 17,150, p < 0.001). Similarly, QALYs at 10-year follow-up were 4.5 ± 0.2 for attempted GTR, 5.7 ± 0.5 for planned subtotal removal plus radiotherapy, and 7.8 ± 0.5 for biopsy plus radiotherapy (F = 6,173, p < 0.001). On post hoc pairwise comparisons, the differences between all pairs compared were also highly significant (p < 0.001). Since follow-up data at 10 years are lacking for endoscopic cases, this category was excluded from 10-year comparisons. Conclusions Biopsy with subsequent radiotherapy is the preferred approach with respect to improved overall quality of life. While endoscopic approaches also show promise in preserving quality of life at five-year follow-up, there are not sufficient data to draw conclusions about this comparison at 10 years.

OBJECTIVE Resection significantly improves the clinical symptoms and functional outcomes of patients with intradural extramedullary tumors. However, patient quality of life following resection has not been adequately investigated. The aim in this retrospective analysis of prospectively collected quality of life outcomes is to analyze the efficacy of resection of intradural extramedullary spinal tumors in terms of quality of life markers. METHODS A retrospective review of a single institutional neurosurgical administrative database was conducted to analyze clinical data. The Oswestry Disability Index (ODI), visual analog scale (VAS) for pain, and the EQ-5D-3 L descriptive system were used to analyze quality of life preoperatively, less than 1 month postoperatively, 1–3 months postoperatively, 3–12 months postoperatively, and more than 12 months postoperatively. RESULTS The ODI scores increased perioperatively at the < 1-month follow-up from 36 preoperatively to 47. Relative to preoperative values, the ODI score decreased significantly at 1–3, 3–12, and > 12 months to 23, 17, and 20, respectively. VAS scores significantly decreased from 6.1 to 3.5, 2.4, 2.0, and 2.9 at the < 1-month, 1- to 3-, 3- to 12-, and > 12-month follow-ups, respectively. EQ-5D mobility significantly worsened at the < 1-month follow-up but improved at the 3- to 12-and > 12-month follow-ups. EQ-5D self-care significantly worsened at the < 1-month follow-up but significantly improved by the 3- to 12-month follow-up. EQ-5D usual activities improved at the 1- to 3-, 3- to 12-, and > 12-month follow-ups. EQ-5D pain and discomfort significantly improved at all follow-up points. EQ-5D anxiety and depression significantly improved at 1- to 3-month and 3- to 12-month follow-ups. CONCLUSIONS Resection of intradural extramedullary spine tumors appears to significantly improve patient quality of life by decreasing patient disability and pain and by improving each of the EQ-5D domains.

Transit Constipation

Background: Surgical treatment of refractory slow transit constipation (STC) is traditionally performed using end-to-side ileorectal anastomosis (SE-IRA) with total abdominal colectomy (TAC). Antiperistaltic side-to-side (SS) IRA is suggested to be a superior approach. Employing a well-characterized cohort of STC patients, we compared the postoperative outcomes of the 2 surgical approaches. Methods: A total of 42 patients underwent TAC for refractory idiopathic STC. Twenty patients were treated using traditional SE-IRA whereas 22 patients were treated using SS-IRA. Patients were evaluated at 3 and 6 months as well as at 1 and 2 years after surgery. Both groups were compared for patient characteristics, perioperative data and quality of life. Cleveland Clinic Incontinence Score (CCIS) and Gastrointestinal Quality of Life Index (GQILI) were adopted for evaluating postoperative recovery. Results: Both study groups were comparable with respect to general patient characteristics, disease severity and post-operative complications. Fewer than 30% of all patients reported substantial dissatisfaction with surgical outcomes in both the groups. The SS-IRA group was associated with a lower postoperative CCIS (p < 0.05) and a better GQILI (p < 0.05) than that of the SE-IRA group during early follow-up examinations. Conclusion: In this study, SS-IRA was superior to traditional SE-IRA for the treatment of STC with respect to post-operative outcomes, and especially during early follow-up.

OBJECTIVEStereotactic radiosurgery (SRS) is increasingly used for the treatment of brain metastasis. To date, most studies have focused on survival, radiological response, or surrogate quality endpoints such as Karnofsky Performance Scale status or neurocognitive indices. The current study prospectively evaluated pre-procedural factors impacting quality of life in brain metastasis patients undergoing SRS.METHODSUsing a national, cloud-based platform, patients undergoing SRS for brain metastasis were accrued to the registry. Quality of life prior to SRS was assessed using the 5-level EQ-5D (EQ5D-L) validated tool; additionally, patient and treatment attributes were collected. Patient quality of life was assessed as part of routine follow-up after SRS. Factors predicting a difference in the aggregate EQ5D-L score or the subscores were evaluated. Pre-SRS covariates impacting changes in EQ5D-L were statistically evaluated. Statistical analyses were conducted using multivariate linear regression models.RESULTSEQ5D-L results were available for 116 patients. EQ5D-L improvement (average of 0.387) was noted in patients treated with earlier SRS (p = 0.000175). Worsening overall EQ5D-L (average of 0.052 per lesion) was associated with an increased number of brain metastases at the time of initial presentation (p = 0.0399). Male sex predicted a risk of worsening (average of 0.347) of the pain and discomfort subscore at last follow-up (p = 0.004205). Baseline subscores of pain/discomfort were not correlated with pain/discomfort subscores at follow-up (p = 0.604), whereas baseline subscores of anxiety/depression were strongly positively correlated with the anxiety/depression follow-up subscores (p = 0.0039).CONCLUSIONSAfter SRS, quality of life was likely to improve in patients treated early with SRS and worsen in those with a greater number of brain metastases. Sex differences appear to exist regarding pain and discomfort worsening after SRS. Those with high levels of anxiety and depression at SRS may benefit from medical treatment as this particular quality of life factor generally remains unchanged after SRS.

Endoscopic Endonasal

Object In the last decade the indications for the endoscopic endonasal approach have been progressively expanded to include lesions that have not been traditionally considered amenable to resection through the transsphenoidal route. In this study, the authors analyze their experience with hypothalamic gliomas treated via the endoscopic endonasal approach. Methods Consecutive cases of hypothalamic gliomas treated since 2007 via an endoscopic endonasal approach were reviewed. Preoperative and postoperative neuroimaging as well as endocrinological, neurological, and visual symptoms were analyzed to assess the surgical outcome. Signs and symptoms of hypothalamic dysfunction including body mass index (BMI), memory, sleep-wake rhythm, and polyphagia were prospectively collected pre- and postoperatively to assess hypothalamic function. Quality of life was evaluated using the Katz scale. Results In the initial phase the endoscopic endonasal approach was adopted in 3 cases with a palliative intent, to obtain a biopsy sample or for debulking of the mass followed by radio- or chemotherapy. In 2 later cases it was successfully adopted to achieve gross-total tumor resection. Complications consisted of 2 postoperative CSF leaks, which required an endoscopic endonasal reintervention. Visual deficit improved in 3 cases and normalized in the other 2. Four patients developed diabetes insipidus, and 3 an anterior panhypopituitarism. All patients had a moderate increase in BMI. No patients presented with any other signs of hypothalamic damage, and their quality of life at follow-up is normal. Conclusions Despite the limitations of a short follow-up and small sample, the authors’ early experience with the endoscopic endonasal approach has revealed it to be a direct, straightforward, and safe approach to third ventricle astrocytomas. It allowed the authors to perform tumor resection with the same microsurgical technique: dissecting the tumor with 2 hands, performing a central debulking, and controlling the bleeding with bipolar coagulation. The main limitations were represented by some anatomical conditions, such as the position of the chiasm and the anterior communicating artery complex and, finally, by the challenge of watertight plastic repair. To definitively evaluate the role of this approach in hypothalamic gliomas, a comparison with transcranial series would be necessary, but due to the rarity of these cases such a study is still lacking. The authors observed that more aggressive surgery is associated with a worse endocrinological outcome; thus they consider it to be an open question (in particular in prepubertal patients) whether radical removal is an advisable goal for hypothalamic gliomas.

OBJECTIVE Cavernous sinus meningiomas (CSMs) represent a cohort of challenging skull base tumors. Proper management requires achieving a balance between optimal resection, restoration of cranial nerve (CN) function, and maintaining or improving quality of life. The objective of this study was to assess the pre-, intra-, and postoperative factors related to clinical and neurological outcomes, morbidity, mortality, and tumor control in patients with CSM. METHODS A retrospective review of a single surgeon's experience with microsurgical removal of CSM in 65 patients between January 1996 and August 2013 was done. Sekhar's classification, modified Kobayashi grading, and the Karnofsky Performance Scale were used to define tumor extension, tumor removal, and clinical outcomes, respectively. RESULTS Preoperative CN dysfunction was evident in 64.6% of patients. CN II deficits were most common. The greatest improvement was seen for CN V deficits, whereas CN II and CN IV deficits showed the smallest degree of recovery. Complete resection was achieved in 41.5% of cases and was not significantly associated with functional CN recovery. Internal carotid artery encasement significantly limited the complete microscopic resection of CSM (p < 0.0001). Overall, 18.5% of patients showed symptomatic recurrence after their initial surgery (mean follow-up 60.8 months [range 3–199 months]). The use of adjuvant stereotactic radiosurgery (SRS) after microsurgery independently decreased the recurrence rate (p = 0.009; OR 0.036; 95% CI 0.003–0.430). CONCLUSIONS Modified Kobayashi tumor resection (Grades I–IIIB) was possible in 41.5% of patients. CN recovery and tumor control were independent of extent of tumor removal. The combination of resection and adjuvant SRS can achieve excellent tumor control. Furthermore, the use of adjuvant SRS independently decreases the recurrence rates of CSM.
