ObjectThe authors conducted a retrospective study to evaluate the efficacy of Gamma Knife surgery (GKS) followed by radiotherapy for the treatment of unresectable glioblastomas multiforme (GBMs) on patient survival and quality of life.MethodsA total of 19 patients with unresectable GBMs located in eloquent areas of the brain were eligible for this study. Beginning in January 2002, 10 patients underwent GKS followed by fractionated radiotherapy. Nine patients who had undergone radiotherapy alone after biopsy-proven diagnosis served as the control group. The mean patient ages were 53 years and 56 years, respectively. Preoperative Karnofsky Performance Scale (KPS) scores were 80 (range 60–100) and 90 (range 50–100), respectively. The median margin dose for GKS was 12 Gy (9–16 Gy), and the total dose for radiotherapy was 60 Gy in 30 fractions. The mean follow-up duration was 7.2 months, the median patient survival time was 52 weeks (95% confidence interval [CI] 22–110.6 weeks) in the GKS group, and the median overall survival time was 28 weeks (95% CI 22.5–33.5 weeks) in the control group. The difference was not statistically significant (p = 0.0758). The estimated progression-free survival rate at 3 months was 75% in the GKS group and 45% in the control group (p = 0.082). The posttreatment KPS scores were either unchanged or improved in the GKS group, whereas it deteriorated by 20 or more points in six of nine patients of the control group (p = 0.004).Conclusions Gamma Knife surgery prior to radiotherapy may be helpful in preserving patients' daily activities in the adjuvant management of unresectable GBM.

Object Stereotactic radiosurgery is an alternative to conventional surgery for the treatment of trigeminal neuralgia. The authors conducted a prospective evaluation of the safety and efficacy of this method in a large series of patients. Methods A total of 100 patients presenting with trigeminal neuralgia were treated and followed up for a minimum of 12 months. The mean age was 68.2 years; 54 patients were male, and 46 were female. Seven had a history of multiple sclerosis, and 42 had already received conventional surgical treatment for trigeminal neuralgia. The intervention consisted of gamma knife surgery to the retrogasserian cisternal portion of the fifth cranial nerve. The median dose used at the maximum was 85 Gy (range 70–90 Gy). The number and intensity of pain attacks were recorded by the patient from 3 months before radiosurgery to a minimum of 12 months after treatment. Before and a minimum of 12 months after treatment, the patient completed a quality-of-life questionnaire. Neurological examination and quantitative sensory testing to evaluate sensory perception were performed by an independent neurologist over this same time period. At the last visit 83 of 100 patients were reported to be pain free. Fifty-eight of these 83 patients had stopped taking medication during the study. All quality-of-life parameters were improved (p < 0.001). Six patients reported facial paresthesia, and four patients reported hypesthesia. These symptoms were classified as mild. None of the complications reported for other techniques were observed. Conclusions Radiosurgery is a safe and effective alternative treatment for trigeminal neuralgia and is associated with a particularly low rate of hypesthesia.

Object Gamma Knife surgery (GKS) has been shown to be effective for treating many patients with brain metastasis. Some brain metastases demonstrate significant peritumoral edema; radiation may induce cerebral edema or worsening preexisting edema. This study was conducted to evaluate the imaging and neurobehavioral outcomes in patients with preexisting peritumoral edema who then undergo GKS. Methods Between August 2003 and January 2008, 63 cases of brain metastasis with significant peritumoral edema (> 20 cm3) were prospectively studied. The study inclusion criteria were as follows: 1) a single metastatic lesion with significant edema (perilesional edema signal volume on FLAIR > 20 cm3); and 2) inclusion of only 1 lesion > 20 cm3 in the study (in cases of multiple lesions noted on FLAIR images). All patients received MR imaging with pulse sequences including T1-weighted imaging and FLAIR with or without contrast and T2-weighted imaging at an interval of 3 months. A neurological assessment and Brain Cancer Module (BCM-20) questionnaire were obtained every 2–3 months. Kaplan–Meier, Cox regression, and logistic regression were used for analysis of survival and associated factors. Results At the time of GKS, the median Karnofsky Performance Scale (KPS) score was 70 (range 50–90), and the mean BCM-20 score was 45.5 ± 6.1. The mean tumor volume (± standard deviation) was 5.2 ± 4.6 cm3 with corresponding T2-weighted imaging and FLAIR volumes of 59.25 ± 37.3 and 62.1 ± 38.8 cm3, respectively (R2 = 0.977, p < 0.001). The mean edema index (volume of peritumoral edema/tumor volume) was 17.5 ± 14.5. The mean peripheral and maximum GKS doses were 17.4 ± 2.3 and 35 ± 4.7 Gy, respectively. The median survival was 11 months. The longer survival was related to KPS scores ≥ 70 (p = 0.008), age < 65 years (p = 0.022), and a reduction of > 6 in BCM-20 score (p = 0.007), but survival was not related to preexisting edema or tumor volume. A reduction in BCM-20 score of > 6 was related to decreased volume in T1-weighted and FLAIR imaging (p < 0.001). Thirty-eight (79.2%) of 48 patients demonstrated decreased tumor volume and accompanied by decreased T2-weighted imaging and FLAIR volume. Eight (16.7%) of the 48 patients exhibited increased or stable tumor volume. A margin dose > 18 Gy was more likely to afford tumor reduction and resolution of peritumoral edema (p = 0.005 and p = 0.006, respectively). However, prior external-beam radiation therapy correlated with worsened preexisting peritumoral edema (p = 0.013) and longer maintenance of corticosteroids (p < 0.001). Conclusions Patients demonstrating a reduction in the BCM-20 score > 6, age < 65 years, and KPS score ≥ 70 exhibited longer survival. Significant preexisting edema did not influence the tumor response or clinical outcome. The resolution of edema was related to better quality of life but not to longer survival.

Object The authors present outcomes obtained in patients who underwent Gamma Knife surgery (GKS) at 1 institution as part of a multimodal treatment of refractory epilepsy caused by hypothalamic hamartomas (HHs). Methods Between 2003 and 2010, 19 patients with HH underwent GKS. Eight patients had follow-up for less than 1 year, and 1 patient was lost to follow-up. The 10 remaining patients (mean age 15.1 years, range 5.7–29.3 years) had a mean follow-up of 43 months (range 18–81 months) and are the focus of this report. Five patients had undergone a total of 6 prior surgeries: 1 transcallosal resection of the HH, 2 endoscopic transventricular resections of the HH, 2 temporal lobectomies, and 1 arachnoid cyst evacuation. In an institutional review board–approved study, postoperative complications and long-term outcome measures were monitored prospectively with the use of a proprietary database. Seven patients harbored Delalande Type II lesions; the remainder harbored Type III or IV lesions. Seizure frequency ranged from 1–2 monthly to as many as 100 gelastic seizures daily. The mean lesion volume was 695 mm3 (range 169–3000 mm3, median 265 mm3). The mean/median dose directed to the 50% isodose line was 18 Gy (range 16–20 Gy). The mean maximum point dose to the optic chiasm was 7.5 Gy (range 5–10 Gy). Three patients underwent additional resection 14.5, 21, and 32 months after GKS. Results Of the 10 patients included in this study, 6 are seizure free (2 after they underwent additional surgery), 1 has a 50%–90% reduction in seizure frequency, 2 have a 50% reduction in seizure frequency, and 1 has observed no change in seizure frequency. Overall quality of life, based on data obtained from follow-up telephone conversations and/or surveys, improved in 9 patients and was due to improvements in seizure control (9 patients), short-term memory loss (3 patients), and behavioral symptoms (5 patients); in 1 patient, quality of life remains minimally affected. Incidences of morbidity were all temporary and included poikilothermia (1 patient), increased depression (1 patient), weight gain/increased appetite (2 patients), and anxiety (1 patient) after GKS. Conclusions Of the approximately 150 patients at Barrow Neurological Institute who have undergone treatment for HH, the authors have reserved GKS for treatment of small HHs located distal from radiosensitive structures in patients with high cognitive function and a stable clinical picture, which allows time for the effects of radiosurgery to occur without further deterioration. The lack of significant morbidity and the clinical outcomes achieved in this study demonstrated a low risk of GKS for HH with results comparable to those of previous series.

Object. The authors analyzed the factors involved in determining prolonged survival (≥ 24 months) in patients with brain metastases treated by gamma knife surgery (GKS). Methods. Between 1995 and 2003, a total of 116 patients underwent 167 GKS procedures for brain metastases. There was no special case selection. Smaller and larger lesions were treated with different protocols. The mean patient age was 56.9 years, the mean number of initial lesions was 3.15, and the mean lesion volume was 10.45 cm.3 The mean follow-up time was 9.2 months. The median patient survival was 8.68 months. One-, 2-, 3-, 4-, and 5-year actuarial survival rates were 31.8%, 19.8%, 14.6%, 7.7%, and 6.9%, respectively. Patient age, number of lesions at presentation, and lesion volume had no influence on patient survival. Twenty-three (19.8%) patients survived for 24 months or more. Certain factors were associated with increased survival time. These were stable primary disease (21 of 23 patients), a long latency between diagnosis of the primary tumor and the occurrence of brain metastases (mean 28.4 months, median 16 months), absence of third-organ involvement, and repeated local procedures. Ten patients underwent repeated GKS (mean 3.4 per patient). Seven patients required open surgery for local treatment failures (recurrence or radiation necrosis). Two patients had both. Fifteen patients underwent repeated procedures. Conclusions. Aggressive local therapy with GKS, repeated GKS, and GKS plus surgery can achieve increased survival in a subgroup of patients with stable primary disease, no third-organ involvement, and long primary-brain secondary intervals.

Background: Radiotherapy (RT) is a choice to manage pelvic organ malignancies that can affect bladder; therefore, it causes radiation cystitis with some bothering urinary symptoms and decreasing the patient’s quality of life. Intravesical hyaluronic acid (HA) is an agent with promising results in some studies for cystitis, and Cystistat is a derivative of hyaluronic acid. Objectives: This clinical trial aimed at evaluating the effects of intravesical instillation of Cystistat on symptoms of radiation cystitis and quality of life (QOL). Methods: A total of 58 patients with radiation cystitis were randomized in 2 groups (case: 30, control: 28). One group received intravesical Cystistat, the other received normal saline weekly for up to 4 weeks and then monthly for up to 2 months. Hematuria, Visual Analog scale (VAS) and QOL based on King’s Health questionnaire were compared before and 3, 6 and 9 months after intravesical instillation. Results: The mean age of the patients was 63.93 ± 10.89 years old. The mean of each sub-category of QOL and total score of QOL, as well as, VAS score were significantly improved in comparison to the control group at each time of follow-ups (P < 0.05). Hematuria was significantly different in the 3rd, 6th and 9th month of follow-ups (P < 0.05). Conclusions: Findings showed that patients with radiation cystitis could significantly benefit from intravesical instillation of HA, their hematuria would be successfully resolved rather than control group in addition to lowering the VAS score, so their QOL would be improved.

Generalized Anxiety Disorder (GAD) is one of the most common anxiety disorders. It has been reported that psychological treatments like Cognitive-Behavioral Therapy (CBT) is effective for patients with GAD. The purpose of the present research was to investigate the effectiveness of CBT on Quality of Life (QOL) and worry in patients with GAD. A sample of 30 patients with GAD who had been referred to psychiatry offices in Isfahan, Iran were selected and assigned into an experimental group (n=15) and a control group (n=15) randomly.  The experimental group received CBT in 8 weekly sessions. All participants completed the World Health Organization Quality Of Life-Brief (WHOQOL-BREF) questionnaire and the Penn State Worry Questionnaire (PSWQ) at pretest, posttest and follow up. The results of MANCOVA showed that the mean scores of QOL in the experimental group was significantly higher than the control group at the posttest and follow up (P<0.05) and the mean scores of worry in the experimental group was significantly lower than the control group at the posttest and follow up (P<0.05) It is concluded that CBT can be applied for the patients with GAD as a useful psychological treatment. In general, CBT can improve QOL and decrease worry in patients with GAD.

Background: The functional deficits in people with fibromyalgia can be related to the level of physical activity performed. This study investigated the effectiveness of an active exercise programme versus exercise for well-being improving pain, flexibility, static balance, perceived exertion and quality of life of women with fibromyalgia; Methods: A randomised, single-blind, controlled trial was conducted. A total of 141 of women diagnosed with fibromyalgia were enrolled and randomised to an active exercise program group (n = 47), where they performed physical active exercises, an exercise for well-being group (n = 47), which performed the Qi Gong exercises named ‘the twenty Wang Ziping figures for health and longevity’, and a control group (n = 47), which did not receive any intervention, for a period of 4 weeks. Measures were taken at baseline and after the treatment. The primary outcome measures were static balance and centre of gravity (Wii-Fit Nintendo ©), flexibility (test de Wells and Dillon), pain (Visual Analogue Scale) and quality of life (Spanish-Fibromyalgia Impact Questionnaire). The secondary outcome measure was the perceived exertion during activity (BORG Scale). Results: In total, 93 participants completed the study. The mean value of the age was 52.24 ± 6.19. The post intervention results showed statistically significant improvements in the exercise for well-being and the active exercise programme groups vs. the control group in relation to pain (p = 0.006 active exercise programme group, p = 0.001 exercise for well-being group), static balance (p < 0.001 active exercise programme group) and quality of life (p < 0.001 active exercise programme group, p = 0.002 exercise for well-being group). In addition, the mean scores related to perceived fatigue during the sessions were 6.30 ± 1.88 for the active exercise programme group and 5.52 ± 1.55 for the exercise for well-being group. These differences were not significant. Conclusions: The active exercise program and exercise for well-being improved flexibility, static balance, pain and quality of life of women with fibromyalgia. The participants of the active exercise programme achieved better results that those of the exercise for well-being.

ObjectPituitary adenomas have been treated using a variety of modalities including resection, medication, fractionated radiotherapy, and stereotactic radiosurgery. The policy has been that all adenomas should first be treated with resection to reduce the volume of the tumor. The authors' study was conducted to determine the efficacy of using Gamma Knife surgery (GKS) for pituitary adenomas invading the cavernous sinus.MethodsOf 397 patients with pituitary tumors who underwent GKS between October 1994 and October 2005, 68 patients had pituitary macroadenomas invading the cavernous sinus. Sixty-seven cases were available for follow up. The mean age of the patients in these cases was 42.8 years (range 14–73 years). The male/female ratio was 0.8:1. The mean adenoma volume was 9.3 cm3. A total of 24 patients had undergone craniotomies and resection, and 11 patients had undergone transsphenoidal surgery prior to GKS. The mean follow-up period was 32.8 months. Tumor control was defined as a decrease or no change in tumor volume after GKS. Endocrinological improvement was defined as a decline in hormone levels to below 50% of the pre-GKS level.Tumor control was achieved in 95.5% of the cases. Endocrinological improvement was achieved in 68% of 25 patients. One patient suffered hypopituitarism after GKS.Conclusions Gamma Knife surgery is a safe and effective treatment for invasive pituitary macroadenoma with few complications.

Object. After radical surgery for childhood cerebellar astrocytomas, patients are considered to be cured. Long-term follow up demonstrates that these patients survive, with most of them leading a normal life. The study reported here was aimed at assessing the quality of life (QOL) of these adults, which is defined as a person's sense of well-being, as derived from his or her current experience of life as a whole. Methods. Twenty patients who had undergone surgery between 1970 and 1985 were enrolled in the study. In four patients ventriculoperitoneal shunts were in place; two of these patients had required more than six shunt revisions. At present, all patients have clear neuroimaging studies and their Karnofsky Performance Scale (KPS) scores are as follows: 70 in three, 80 in seven, 90 in six, and 100 in four. A QOL questionnaire was administered to the patients and to a control group consisting of 20 healthy volunteers of matching age and sex. The chi-square test was applied to compare patients and controls. Traditional questions on the level of education, work, whether the patients have their own families, and whether they possessed a driver's license were asked at the end of the questionnaire. In all the dimensions assessed except one (sex life), the difference between patients and control volunteers was significant, socializing and adolescence being the most striking ones. This was also true when the three patients with the lowest KPS scores and the worst QOL results were excluded. Conclusions. By traditional standards, these patients appear to fare quite well. Nevertheless, their self-reported life experience is unsatisfying when compared with the control group. The authors conclude that psychosocial factors are critical to complete recovery and the QOL of children who undergo successful operations for benign cerebellar astrocytoma.

Object There are various surgical treatment alternatives for trigeminal neuralgia (TN), but there is no single scale that can be used uniformly to assess and compare one type of intervention with the others. In this study the objectives were to determine factors associated with pain control, pain-free survival, residual pain, and recurrence after gamma knife surgery (GKS) treatment for TN, and to correlate the patients' self-reported quality of life (QOL) and satisfaction with the aforementioned factors. Methods Between the years 2000 and 2004, the authors treated 81 patients with medically refractory TN by using GKS. Fifty-two patients responded to a questionnaire regarding pain control, activities of daily living, QOL, and patient satisfaction. The median follow-up duration was 16.5 months. Twenty-two patients (42.3%) had complete pain relief, 14 (26.9%) had partial but satisfactory pain relief, and in 16 patients (30.8%) the treatment failed. Seven patients (13.5%) reported a recurrence during the follow-up period, and 25 (48.1%) reported a significant (> 50%) decrease in their pain within the 1st month posttreatment. The mean decrease in the total dose of pain medication was 75%. Patients' self-reported QOL scores improved 90% and the overall patient satisfaction score was 80%. Conclusions The authors found that GKS is a minimally invasive and effective procedure that yields a favorable outcome for patients with recurrent or refractory TN. It may also be offered as a first-line surgical modality for any patients with TN who are unsuited or unwilling to undergo microvascular decompression.
