Objective : Prognostic factors of metastatic brain tumors have been widely reported and their operative indications also have been extended gradually even to the poor grade patients. Authors intended to analyze the causative factors for the clinical outcome of metastatic brain tumors, especially with relevant to the poor prognosis by one year follow-up evaluation. Patients and Methods : The authors retrospectively studied the clinical characteristics of 46 cases(35 patients) with metastatic brain tumors among 466 cases(437 patients) which were operated on due to the brain tumor, during the period between January 1994 to June 1999. Statistical analysis was performed by using SPSS 8.0$^{(R)}$. A p-value of less than 0.05 was considered clinically significant. Result : Among the variable clinical factors in patients with metastatic brain tumors, Karnofsky Performance Scale (KPS) score of less than 70(16 patients), uncontrolled primary tumor(8 patients), and surgical resection without further adjuvant therapy(9 patients) showed statistically significant poor prognosis ; p value of 0.002, 0.032, and 0.001, respectively. Other tested variables, such as old age(greater than 65 years ; 10 patients), gender(male ; 20 patients), type of primary cancer(primary undefined ; 6 patients, lung cancer ; 15 patients), location(infratentorial ; 9 patients, sellar ; 5 patients), number of lesion(multiple ; 12 patients), and number of operation(multiple craniotomy ; 7 patients) were not related to the poor prognosis. Conclusions : The most common primary site of distant metastasis was lung. The poorer prognosis was highly correlated with various factors including low KPS score(<70), no postoperative adjuvant therapy, and uncontrolled primary tumors.
Malignant glioblastoma multiforme (GBM) is the most malignant brain tumor and despite recent advances in diagnostics and treatment prognosis remains poor. In this retrospective study, we assessed the clinical and radiological parameters, as well as fluorescence in situ hybridization (FISH) of 1p19q deletion, in a series of cases. A total of 816 patients with GBM who received surgery and radiation between January 2010 and May 2014 were included in this study. Kaplan-Meier survival analysis and Cox regression analysis were used to find the factors independently influencing patient progression free survival (PFS) and overall survival (OS). Age at diagnosis, preoperative Karnofsky Performance Scale (KPS) score, KPS score change at 2 weeks after operation, neurological deficit symptoms, tumor resection extent, maximal tumor diameter, involvement of eloquent cortex or deep structure, involvement of brain lobe, Ki-67 and MMP9 expression level and adjuvant chemotherapy were statistically significant factors (p<0.05) for both PFS and OS in the univariate analysis. Cox proportional hazards modeling revealed that age ${\leq}50$ years, preoperative KPS score ${\geq}80$, KPS score change after operation ${\geq}0$, involvement of single frontal lobe, deep structure involvement, low Ki-67 and MMP9 expression and adjuvant chemotherapy were independent favorable factors (p<0.05) for patient clinical outcomes.

Objective : This study was performed to assess the efficacy of GKS in patients with ten or more brain metastases. Methods : From Aug 2002 to Dec 2007, twenty-six patients (13 men and 13 women) with ten or more cerebral metastatic lesions underwent GKS. The mean age was 55 years (32-80). All patients had Karnofsky performance status (KPS) score of 70 or better. According to recursive partitioning analysis (RPA) classification, 3 patients belonged to class I and 23 to class II. The location of primary tumor was lung (21), breast (3) and unknown (2). The mean number of the lesions per patient was 16.6 (10-37). The mean cumulated volume was 10.9 cc (1.0-42.2). The median marginal dose was 15 Gy (9-23). Overall survival and the prognostic factors for the survival were retrospectively analyzed by using Kaplan Meier method and univariate analysis. Results : Overall median survival from GKS was 34 weeks (8-199). Local control was possible for 79.5% of the lesions and control of all the lesions was possible in at least 14 patients (53.8%) until 6 months after GKS. New lesions appeared in 7 (26.9%) patients during the same period. At the last follow-up, 18 patients died; 6 (33.3%) from systemic causes, 10 (55.6%) from neurological causes, and 2 (11.1 %) from unknown causes. Synchronous onset in non-small cell lung cancer (p=0.007), high KPS score (${\geq}80$, p=0.029), and controlled primary disease (p=0.020) were favorable prognostic factors in univariate analysis. Conclusion : In carefully selected patients, GKS may be a treatment option for ten or more brain metastases.
Objective : Tumours of the brain are a rare occurrence accounting for approximately 2% of all neoplasms in adults. Few studies have been done in Nigeria on the profile of brain tumours. The aim of this study is to determine the profile of brain tumours in general and determine the change in Kanofsky Performance Score (KPS) after treatment. Methods : This is a prospective hospital-based study in Kaduna. All consecutive patients over 18 years of age with diagnosis of brain tumours from January 2016 to December 2019 were included in the study. Demographic and clinical data was collected using a proforma during the study. Patients who received treatment were followed up for 12 months. The primary outcome data was the difference in the quality of life as measured by KPS at the point of first contact and at 1-month after treatment and at 12-month follow up. Data obtained was analysed with SPSS version 25.0 for Windows. Descriptive statistics was done to determine the profile. Paired t-test at 95% confidence interval was done to check for significant correlation between the mean KPS. Results : A total of 39 consecutive patients were included in the study. There was a slight male preponderance with a M : F of 1.17 : 1. Meningioma and metastasis were more common in females while gliomas and pituitary tumours were more common in males. The mean age of patients was 49.8 years and standard deviation of 11.8 years. Pituitary tumours were the most common tumours. The most common location of the tumour was frontal lobe followed by the pituitary gland. The mean duration of symptoms before neurosurgical consultation was 38 weeks. The most common presenting symptoms of patient with brain tumour was headache. The quality of life improve compare to the baseline in 81% of patient at discharge and at 1 year follow up. The overall mortality rate was 25.6%. Conclusion : The most common brain tumour in our study is pituitary tumour. Most patients present late. The most common presenting symptoms is headache. There is significant improvement in the KPS of patients following treatment. The overall mortality rate at 1-year post treatment is 25.6%.

Objectives : In spinal metastasis and myeloma, percutaneous vertebroplasty could be an effective treatment method to provide spinal stabilization and to relief pain for early rehabilitation. The authors report twenty-five cases the clinical results of percutaneous vertebroplasty for twenty-five cases of spinal metastasis and myeloma. Materials and Methods : From September 1998 to December 1999, seventy percutaneous vertebroplasties(PVP) were performed for spinal metastases and myeloma in 25 patients, sixteen women and nine men ranging in age from 34 to 74. The primary malignancies were 6 multiple myelomas, and in metastatic tumore from various origin. All patients complained of severe pain and had osteolytic vertebral body destructions without spinal cord compression. To evaluate clinical improvement, suObjective verbal analogue pain score(VAS) and Karnofsky performance scale(KPS) were used. Thin sliced(2mm-thickness) sectional computed tomography(CT) was performed before and after PVP. Plain X-ray film was followed up every 1 month to assess the vertebral column stability. Results : In 25 patients, a total of seventy PVPS were performed successfully : 6 cervical, 33 thoracic and 31 lumbar vertebrae. Most patients had clear improvement of pain after PVP ; mean as score was 8.1 and 2.9 before and after PVP, respectively. Improvement was maintained in most patients. No further collapse of treated vertebrae was observed(mean follow-up, 7 months). Leakage of PMMA was notod in the spinal canal(13 levels), neural foramen (2 levels), adjacent disk(15 levels), paravertebral soft tissue(14 levels) and vein(8 levels). Pulmonary embolism was detected in three patients after the procedure, but was not associated with clinical symptoms. Conclusion : These results indicate that percutaneous vertebroplasty can be valuable treatment method in osteolytic spinal metastasis and myeloma, providing immediate pain relief and spinal stabilization and contributing to early rehabilitation.

Objectives : Lung cancer is one of the most common cancer and the leading cause of cancer deaths worldwide. This study aimed to evaluate the role of acupuncture as an adjunctive therapy for lung cancer. Methods : We conducted a systematic review and meta-analysis on the role of acupuncture therapy in lung cancer treatment by electronic and manual searching in ninedatabases, including PubMed, Cochrane library, Embase, Korean databases, and Chinese medical databases. Results : A total of 21 trials were included in the meta-analysis. The study results showed that acupuncture therapy had significant efficacy in immuneregulation, including CD3 andCD4. Further analysis revealed that acupuncture therapy significant improvements in quality of life, including Karnofsky performance status(KPS)score, functional assessment of cancer therapy-lung cancer subscale (FACT-L) and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). In addition, the pooled studies also showed that acupuncture therapy reduced cancer pain and chemotherapy-induced nausea and vomiting. Conclusions : Our study provides moderate evidence of the efficacy of the acupuncture therapy in the treatment of lung cancer.

Manufacturing a multi-layered tablet such as Xatral XL$^{(R)}$ is more complex and expensive than monolayered tablets, but mono-layered tablets may have less favorable release properties depending on the pharmacodynamics and pharmacokinetics of the active ingredient. We therefore sought to develop a monolayer tablet with a similar dissolution profile to the commercial alfuzosin sustained-release triple layered tablet (Xatral XL$^{(R)}$). We prepared four different mono-layered alfuzosin tablets with different concentrations of hydroxypropyl methycellulose and PVP K-90. Fomulation III with alfuzosion/mg-stearate/ HPMC/ PVP K-90 (10/5/110/95 mg/tab) has a similar dissolution rate to Xatral XL$^{(R)}$, with a similarity factor score of 81.4. However, the swelling and erosion rates of the two formulations were different, and NIR analysis showed differences in the mechanisms of drug release. Thus, although formulation III and Xatral XL$^{(R)}$ show similar dissolution rates, the mechanisms of drug release are different.
Objectives: To assess the efficacy, side effects, and the impact on quality of life with $Qinin^{(R)}$ (Cantharidin sodium) injection combined with chemotherapy for gastric cancer patients. Method: A consecutive cohort of 70 patients were divided into two groups: experimental group with cantharidin sodium injection combined with chemotherapy, while the control group received chemotherapy alone. After more than two courses of treatment, efficacy, quality of life and side effects were evaluated. Results: The response rate of experimental group was not significantly different from that of the control group (P>0.05), but differences were significant in clinical benefit response and KPS score. In addition, gastrointestinal reactions and the incidence of leukopenia were lower than in the control group (P<0.05). Conclusions: $Qinin^{(R)}$ (Cantharidin sodium) injection combined with chemotherapy enhances clinical benefit response, improving quality of life of gastric cancer patients and reducing side effects of chemotherapy. Thus $Qinin^{(R)}$ (Cantharidin sodium) injection deserves to be further investigated in randomized control clinical trails.

A fifty-year-old female non-smoker with no other specific medical history visited our institute. She complained of axial back pain with no other neurological deficit. Chest X-ray, chest computed tomography (CT) scan, CT-guided needle aspiration biopsy, whole-body positron emission tomography, spine CT and spine magnetic resonance image findings suggested NSCLC with epidermal growth factor receptor (EGFR) mutation, multiple brain metastases, and two isolated metastases to the T3 and L3 vertebral bodies. She underwent chemotherapy with gefitinib ($Iressa^{TM}$) for NSCLC and gamma knife surgery for multiple brain metastases. We performed a two-staged, total en bloc spondylectomy of the T3 and L3 vertebral bodies based on several good prognostic characteristics, such as the lack of metastases to the appendicular bone, good preoperative performance status, and being an excellent responder (Asian, never-smoker and adenocarcinoma histology) to EGFR inhibitors. Improved axial back pain after the surgery enabled her to walk with the aid of a thoracolumbosacral orthosis brace on the third postoperative day. Her Karnofsky performance status score (KPS) was 90 at the time of discharge and has been maintained to date 3 years after surgery. In selected NSCLC patients with good prognostic characteristics, we suggest that locally curative treatment such as total en bloc spondylectomy or radiosurgery should be emphasized to achieve longer term survival for the selected cases.
Objective : We treated 10 pediatric diffuse intrinsic brain stem glioma[BSG] patients with Novalis system [linac based radiotherapy unit, Germany] and examined the efficacy of the Fractionated Stereotactic Radiotherapy[FSRT]. Methods : A retrospective review was conducted on 10 pediatric diffuse intrinsic BSG patients who were treated with FSRT between May, 2001 and August, 2004. The mean age of the patient group was 7.7 years old. Male to female ratio was 4 to 1. The mean dose of FSRT was 38.7Gy, mean fractionated dose was 2.6Gy, mean fractionation size was 16.6, and target volume was $42.78cm^3$. The mean follow up period was 14 months. Results : Four weeks after completion of FSRT, improvements on neurological status and Karnofsky performance scale[KPS] score were recorded in 9/10 (90%] patients and magnetic resonance imaging[MRI] showed decrease in target tumor volume in 8 pediatric patients. The median survival period was 13.5 months after FSRT and treatment toxicity was mild. Conclusion : It is difficult for surgeons to choose surgical treatment for diffuse intrinsic BSG due to its dangerous anatomical structures. FSRT made it possible to control the tumor volume to improve neurological symptoms with minimal complications. We expect that FSRT is a feasible treatment modality for pediatric diffuse intrinsic BSG with tolerable toxicities.
