Intra-arterial ACNU and carboplatin versus intravenous chemotherapy with cisplatin and BCNU in newly diagnosed patients with glioblastoma.

Thirty glioblastoma patients treated at our institute between April 1998 and September 1999 were randomized in a two-arm study to receive carboplatin plus ACNU intraarterial (IA) chemotherapy (arm A) or cisplatin plus BCNU intravenous (IV) treatment (arm B). After the second course of chemotherapy and before the third cycle they also received concomitant radiotherapy, consisting of a median dose of 56.5 Gy. There were 3 (21.4%) partial responses and 11 (78.6%) disease stabilizations in group A. There were 5 (33%) partial responses and 10 disease stabilizations in group B. Time to tumor progression was 5.2 and 5.8 months for IA and IV treatment respectively. Median survival time was 18.3 months for arm A patients and 18.6 for arm B patients. Our IA chemotherapy schedule has produced no conclusive evidence of benefit compared with intravenous treatment. Moreover, its cost-benefit ratio is not good enough to justify its continued pursuit.

Efficacy of intratumoral delivery of mitoxantrone in recurrent malignant glial tumours.

Ninety-nine patients bearing recurrent malignant glioma sequentially selected according to strict eligibility criteria (72 GBL and 27 AA) entered the study. All patients were previously managed with radiotherapy 60 Gy total dose and chemotherapy with nitrosoureas and platinum compounds. At recurrence they were subdivided in homogeneous groups, all treated with the same systemic chemotherapy protocol: 27 GBL (group A) only systemically treated, 20 GBL (group B) treated also locally by delivering 4mg of mitoxantrone every 20 days through the Ommaya reservoire, and 25 GBL (group C) treated with a second surgery and locally as group B. Of the AA group, 13/27 were treated locally trough the Ommaya reservoir after repeat surgery. A trend to different demographic features among subgroups (with locoregionally treated patients and patients undergoing repeat surgery being younger than the others) was seen in this non-randomized study, but this was not statistically significant. Median overall survival was 27, 26 and 15.5 months respectively for groups c, b and a (log-rank = 0.1). After tumor recurrence median survival was 16.8, 12 and 6.6 months respectively for groups c, b and a (log-rank = 0.001) For the 29 AA, overall survival was 48.5 and 100 months (log-rank = 0.03) if treated locally with second tumor debulking. Our results stress the opinion that a second operation could be indicated only if it is a part of a therapeutic protocol to allow a locoregional treatment. Moreover we can finally assume that local delivery of chemotherapy after tumor recurrence, possibly extends patients survival but certainly improves the number of long-survivors.

Embryonal tumors in the adult population: implications in therapeutic planning.

The natural history of neuroectodermal tumors is still debated as far as prognostic factors are concerned; the same uncertainty applies to the optimal radiotherapy schedule and even more to the presumptive additive effect of chemotherapy. The rarity of these tumors and the heterogeneity of management make interpretation of literature data also more difficult. We evaluated clinical course in a cohort of 39 patients, including 31 with medulloblastoma (MB) and 8 with primitive neuroectodermal tumors (PNET). All patients were treated with radiotherapy, a standardized chemotherapy protocol including PCV scheme, and a second-line chemotherapy with cisplatin and etoposide (VP16) at recurrence. In 27 patients, intrathecal chemotherapy was also delivered. Median follow-up was 10.8 years. Overall, PNET had a worse outcome as compared to MB: median survival times were 42.8 vs. 92.6 months, respectively (p = 0.05). At 5 years, 45% of MB patients are alive. No significant difference in disease-free period was found between patients of different age, desmoplastic variant, tumor localization, or extent of surgery. Patients considered to be "high risk" had a significantly shorter disease-free period as compared with low-risk patients (27 vs. 54.7 months, p = 0.04). Systemic or intrathecal chemotherapy did not influence progression-free survival (PFS). However, in the majority of chemotherapy-treated patients, a low-dose craniospinal radiotherapy was also delivered. This combination of treatments may have avoided the expected increased percentage of failure. Moreover, more than half of recurrent patients had a partial response to chemotherapy that extended survival for approximately 3 years. Repeated surgery and chemotherapy at recurrence favorably influenced survival time.

Phenotypic manifestations associated with CAG-repeat expansion in the androgen receptor gene in male patients and heterozygous females: a clinical and molecular study of 30 families.

Spinal and bulbar muscular atrophy (Kennedy disease) is an adult form of X-linked motor neuron disease caused by the expansion of a polymorphic CAG-repeat sequence in the first exon of the androgen receptor gene. We studied clinical and molecular features of 36 patients and 19 heterozygous females. Phenotypic manifestations and disease severity broadly varied among our spinal and bulbar muscular atrophy patients. The size of CAG expansion significantly influences the age of disease onset, but neither clinical features nor disease severity. The majority of carrier women presented signs of chronic denervation at neurophysiological examination and, in three cases, low-amplitude sensory action potentials were recorded. Notably, a few women developed mild signs of bulbar motor neuron impairment later in life. The identification of a large number of patients by the use of the molecular test further supports the hypothesis that Kennedy disease had been previously underdiagnosed, probably because of the great variability of clinical presentation. Although an early diagnosis may not be crucial for treatment, given the lack of effective therapy, the molecular testing can be of great relevance for disease prognosis and genetic counseling.

Cisplatin and BCNU chemotherapy for anaplastic oligoastrocytomas.

In this study 32 newly diagnosed anaplastic oligoastrocytoma patients were enrolled (median age of 41 years, range 19-63; median Karnofsky performance status of 90, range 70-100). All patients were treated with Cisplatin (109 mg/m2) and BCNU (160 mg/m2). The chemotherapy started in the first week after surgery and it was administered every 6 weeks (5 scheduled cycles) for a total of 127 cycles. After the second cycle of chemotherapy all patients received radiotherapy (56.5 Gy). The median follow-up was 63.2 months (10-91). Nine patients were reoperated-on. The median time to tumor progression (TTP) and median survival time (ST) for the whole group of patients were 54.6 and 70.1 months, respectively. A proportional hazard model was used to look at potential prognostic factors for survival including lower age (< 40 years), extent of surgery (total/subtotal versus partial) and reoperation. When we analyzed the group of patients with total/subtotal surgery or age under 40 years the median ST could not be assessed due to the high number of surviving patients after a follow-up of 52 months. The median ST for the older patients or for patients partially operated-on was 54.1 and 42.2 months. In our study only total/subtotal surgery predicted for longer survival (p < 0.001). This schedule of treatment provides durable response in a selected group of anaplastic oligoastrocytoma patients.

Circulating intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and plasma thrombomodulin levels in glioblastoma patients.

Cellular adhesion molecules have been implicated in tumor progression and metastasis. Serum samples from 22 patients with glioblastoma (GBM), before surgery, and 19 sex and age matched healthy controls were analyzed for circulating levels of ICAM-1 and VCAM-1. At the same time also soluble plasma thrombomodulin, a marker of endothelial cell damage and activation, was detected. Soluble ICAM-1 and VCAM-1 levels were comparable in glioblastoma patients and healthy controls, while plasma thrombomodulin (TM) was significantly increased in cancer patients. There was no correlation between thrombomodulin levels and the presence of an intratumoral hemorrhage detected by CT scan, while entity of post-contrast enhacemement at CT correlated with higher TM levels. Further study with serial sampling of GBM patients and correlation with enhancement at CT will allow to ascertain the value of serum TM as a marker of disease recurrence or angiogenesis in those tumors.

Physical rehabilitation has a positive effect on disability in multiple sclerosis patients.

BACKGROUND: Although physical rehabilitation is commonly administered to MS patients, its efficacy has not been established. OBJECTIVE: We assessed the efficacy of an inpatient physical rehabilitation program on impairment, disability, and quality of life of MS patients with a randomized, single-blind, controlled trial. METHODS: Fifty ambulatory MS patients were assigned to 3 weeks of inpatient physical rehabilitation (study treatment) or exercises performed at home (control treatment). Patients were evaluated at baseline and at 3, 9, and 15 weeks by a blinded examining physician. RESULTS: No changes in impairment occurred in either group, as measured by the Expanded Disability Status Scale. At the end of the intervention the study group improved significantly in disability, as assessed by the Functional Independence Measure (FIM) motor domain, compared with controls (p = 0.004), and the improvement persisted at 9 weeks (p = 0.001). The effect size statistic was usually large or moderate in all scale scores of the FIM motor domain at 3 weeks and moderate to fair thereafter. The study group also improved in overall health-related quality of life profile compared with controls; however, the difference was significant only for the mental composite score at 3 (p = 0.008) and 9 weeks (p = 0.001). CONCLUSIONS: Despite unchanging impairment, physical rehabilitation resulted in an improvement in disability and had a positive impact on mental components of health-related quality of life perception at 3 and 9 weeks.

Locally delivered chemotherapy and repeated surgery can improve survival in glioblastoma patients.

We treated 54 patients, newly diagnosed for glioblastoma, with systemic chemotherapy (carmustine (BCNU) 100 mg/m2 and cisplatin 90 mg/m2 every 6 weeks) and radiotherapy soon after surgery. In 10 cases the treatment was combined with locoregional chemotherapy (1 mg bleomycin on days 1-2, and 3 mg mitoxantrone on day 3, repeated every 20 days) administered from an Ommaya reservoir. At tumor recurrence, all patients were treated with procarbazine, lomustine and vincristine (PCV); 15 of 54 were reoperated and treated with locoregional chemotherapy. The median time to disease progression (TTP) and overall survival time (ST) for the whole group were 10.8 and 23.1 months, respectively. The ST of the 15 reoperated patients who also received locoregional treatment at disease recurrence was 27.6 months; this was significantly longer than that of patients not reoperated and not treated locally (log-rank p=0.04). The results in our reoperated subgroup support the opinion that a second operation could be suitable if it is part of the whole program of treatment.

Affective disorders and multiple sclerosis: a controlled study on 65 Italian patients.

A high prevalence of major mood disorders in multiple sclerosis (MS) patients has been reported. In this study, we investigated the frequency of previous or present major mood disorders in 65 patients with clinically definite multiple sclerosis (Poser criteria) and in 31 polyneuropathy (PNP) patients. All patients underwent a questionnaire designed after DSM-IV definitions for major mood disorders. A higher lifetime risk for development of a major mood disorder was evident in MS patients (log rank test, p<0.001). Of all MS patients with a major mood disorder, at least 34% had one first-degree relative affected by a mood disorder, while the corresponding figure was 14% among PNP cases. Our data confirm the high lifetime risk for depression in MS patients and suggest that, at least in a subset of MS patients with depression, the genetic basis for depression operates with similar mechanisms as those at work in families with primary depression. However, this is not necessarily true for other subsets of depressed MS patients' families.

Cyclophosphamide in chronic progressive multiple sclerosis: a comparative study.

No effective treatment is presently available for progressive multiple sclerosis (MS). Cyclophosphamide (CFX), a cytotoxic immunosuppressive drug widely used in systemic dysimmune diseases, has been proposed for the treatment of multiple sclerosis with different schedules and controversial results. To evaluate the safety and clinical efficacy of CFX, we compared three different treatment schedules in patients with progressive MS: induction followed by bimonthly boosters for one year (17 patients); bimonthly boosters for one year without previous induction (15 patients); and monthly boosters for one year (21 patients). Survival analysis showed that the percentage of stable patients was significantly higher in the first and third treatment schedule groups. Myelotoxicity occurred in patients treated with induction and boosters (Group A). A high incidence of broncopneumonia was observed in patients undergoing the second treatment schedule (Group B). No major effects were observed in patients treated with monthly boosters (Group C). Response to treatment was limited to secondary progressive form. This study suggests that monthly treatment with CFX might be safely administered in progressive MS patients; its clinical efficacy must be confirmed by an appropriately designed clinical trial.

Meningo-cortical calcifying angiomatosis and celiac disease.

A woman with ophthalmic migraine was found to have bilateral cerebellar and cerebral calcifications. She progressively developed severe intracranial hypertension, with swelling of the brain and downward transtentorial and tonsillar herniation. Because steroid treatment was ineffective, the right occipital pole was resected. Histological study demonstrated meningo-cortical calcifying angiomatosis. Within 2 months, brain swelling and papilledema disappeared. Subtle signs of malabsorption led to the hypothesis of celiac disease, confirmed by jejunal biopsy. Similar cerebral histological findings have been reported in the brain of two young patients affected by epilepsy and celiac disease. The association between cerebral calcifications and celiac disease is peculiar; the pathogenetic relationship is unknown.

Immunological monitoring of azathioprine treatment in multiple sclerosis patients.

Despite the longstanding clinical use of azathioprine as an immunosuppressive agent in multiple sclerosis, little is known about the action of this drug on a number of parameters of putative pathogenic relevance in the disease. Eleven patients with multiple sclerosis, treated with azathioprine 2.5-3 mg/kg per day, and six untreated patients were studied with serial blood sampling for 1 year. The following immunological parameters were investigated: peripheral blood lymphocyte subsets, natural killer activity, serum IgG, IgM, ICAM-1 and tumour necrosis factor alpha (TNF-alpha). The most relevant changes included a decrease in CD3- CD56+ cells, an increase in CD4+ CD45RA+ cells and a decrease in TNF-alpha levels only in treated patients, while no changes occurred in untreated patients over a 1-year period. The decrease in TNF-alpha levels and the increase in "suppressor-inducer" lymphocytes could reduce chronic inflammation in multiple sclerosis, and paralleled an overall favourable clinical response to azathioprine treatment in our patients.

Low serum interleukin-10 levels in multiple sclerosis: further evidence for decreased systemic immunosuppression?

Serum interleukin 10 (IL10) levels were assessed in patients with multiple sclerosis who were either in a stable or active clinical condition. The levels were compared with values in healthy controls. Lower IL10 levels than in controls were seen in multiple sclerosis patients, regardless of clinical disease activity. Low IL10 levels were also seen in patients with systemic lupus erythematosus. No clear-cut relationships emerged between IL10 levels and those of tumour necrosis factor alpha and transforming growth factor beta, or between IL10 and lymphocyte subsets in peripheral blood.

Does a placebo-effect exist in clinical trials on multiple sclerosis? Review of the literature.

To verify whether the outcome in placebo-treated MS patients actually corresponds to that expected on the basis of the natural history and pretrial evolution of the disease, we here review the results of clinical trials conducted according to a placebo-controlled, randomized design, regardless of the experimental therapy used. The frequency of relapse in remitting-relapsing patients decreases during follow-up, and disability in progressive cases increases more slowly than before enrollment. These data should be borne in mind when evaluating the impact of experimental drugs on the natural course of the disease.

Parallel fluctuations of psychiatric and neurological symptoms in a patient with multiple sclerosis and bipolar affective disorder.

The case of a female patient affected by simultaneously onsetting multiple sclerosis and bipolar affective disorder at age 33 is reported. Over the following years, the patient displayed minor mood fluctuations but, at the ages of 41 and 42 years, respectively, she suffered from a major depressive and a manic episode, both of which were concomitant with a marked worsening in her neurological condition.
