Needs of neuro-oncological patients and their caregivers during the hospitalization and after discharge: results from a longitudinal study

PURPOSE

The aims of this study are to identify neuro-oncological patients' and their caregivers' needs during hospitalization (T0) and at 4 months after discharge (T1); to analyze the longitudinal changes in patients' and caregivers' needs and burden; to identify correlations between patients' needs and caregivers' burden and needs.

METHODS

A pilot observational longitudinal study was conducted on 94 neuro-oncological patients and their caregivers using NEQ to evaluate patients' needs, CNA, and FSQ for caregivers' needs and burden at T0 and T1. Descriptive statistics were performed to illustrate the distribution of questionnaires' scores. The longitudinal change of NEQ, FSQ, and CNA scores were investigated using Wilcoxon test. Spearman's correlation was used to measure the relation between NEQ and FSQ and CNA scores.

RESULTS

The most frequent patients and caregivers' needs were material and informative. Needs tend to decrease over time; in particular FSQ factor "need for knowledge about the disease", CNA factor "Information/communication needs" and CNA total score significantly decreased (p < 0.001). NEQ total score significantly correlated with FSQ factors "emotional burden" and "need for knowledge about the disease" and CNA total and factors scores at T0 and T1. At T0, NEQ correlated significantly with FSQ factor "thoughts about death", while at T1, it correlated with FSQ factor "problems in social involvement".

CONCLUSIONS

It is crucial to plan an assessment of patients' and caregivers' needs from the very beginning, in order to identify those individuals potentially at risk of developing high level of distress and to provide information and support following the illness trajectory of the brain tumor.

Safety and efficacy of primary central nervous system lymphoma treatment in elderly population

Elderly patients represent an important subgroup in primary central nervous system lymphoma (PCNSL) that accounts for approximately half the cases. Furthermore age represents one of the heaviest prognostic factors and in some cases it has more effect on survival than therapies. We performed a retrospective analysis to assess the toxicity and the efficacy of high-dose methotrexate (HDMTX) chemotherapy in a PCNSL population older than 70 years. Seventeen consecutive immunocompetent patients older than 70 years, with histologically confirmed PCNSL, without systemic involvement, treated with HDMTX at our institution between May 2005 and April 2013, were retrospectively evaluated. Main outcome measures were acute toxicity and tumour response. No evidence of haematological toxicity was recorded in 47 % of patients and no deaths related to toxicity grade were reported. Patients achieved a partial response after 3 cycles of chemotherapy in 53 % of cases. The median overall survival (m-OS) from diagnosis was 20.9 months (range 5.2-34 months), with OS-12 of 58.8 % and an OS-24 of 45.4 %. Since there is no standard of care in the treatment of PCNSL in elderly population, it should be taken into account that elderly patients not always can be considered "fragile" and the general tendency to less treat to avoid severe toxicity should not be the rule.

Clinical management of grade III oligodendroglioma

Oligodendrogliomas represent the third most common type of glioma, comprising 4%-15% of all gliomas and can be classified by degree of malignancy into grade II and grade III, according to WHO classification. Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic oligodendroglioma (AO) is often localized as a single lesion in the white matter and in the cortex, rarely in brainstem or spinal cord. The management of AO is deeply changed in the recent years. Maximal safe surgical resection followed by radiotherapy (RT) was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall survival (OS) and progression-free survival (PFS), from the addition of chemotherapy to RT. Allelic losses of chromosomes 1p and 19q occur in 50%-70% of both low-grade and anaplastic tumors, representing a strong prognostic factor and a powerful predictor of prolonged survival. Several other molecular markers have potential clinical significance as IDH1 mutations, confirming the strong prognostic role for OS. Malignant brain tumors negatively impacts on patients' quality of life. Seizures, visual impairment, headache, and cognitive disorders can be present. Moreover, chemotherapy and RT have important side effects. For these reasons, "health-related quality of life" is becoming a topic of growing interest, investigating on physical, mental, emotional, and social well-being. Understanding the impact of medical treatment on health-related quality of life will probably have a growing effect both on health care strategies and on patients.

Privacy-solidarity conflict: the communication with the support group

Actually guidelines require that patient must be informed about his condition so that he can choose the persons he wants to share these information with. Nonetheless, the caregiver usually gets an intermediary role in doctor-patient communication thus becoming the doctor's main conversation partner and claiming to be given more information than the patient himself. A more complex situation is about brain tumours patients sometimes affected by cognitive deficiencies, compromising their comprehension skills or their capability of keeping the information they are being given. A preliminary study allowed to submit separately to brain tumour patients and their family members a semi-structured interview. Although doctors communicate diagnosis and therapeutic plans, patients and their family members often do not seem to remember the information they are given. An important percentage of patients and their carers cannot tell correctly what they was said by the doctors. Only a minor percentage of patients do not want to know all details of their disease. Instead, most of the family members, would rather their beloved were given just partial information on their conditions or even not given information at all. Communication with patients and their carers requires careful re-negotiation in a multiple time-points, rather than a one-off communication episode.

Neuro-oncological diagnosis in patients without histological confirmation

The impossibility to conduct a histological diagnosis could be due to different reasons: (1) patient's refusal to undergo surgery/biopsy. (2) Technical difficulties: despite the advance in surgical procedures, the removal of lesions that are located either in critical or in deep areas represents a considerable risk for patients. (3) Quality/quantity of the sample. In rare cases even when the surgical sample is achieved it could be impossible to reach a histological confirmation, for example due to the small amount of tissue obtained. The lack of histology leads to suboptimal therapy, incorrect prognosis, and misinterpretation of clinical trials and furthermore undermines the possibility to perform most radiation and chemotherapy protocols. In this setting the morphological data obtained with conventional MR imaging may be integrated with the metabolic, structural and perfusional information provided by new MR and metabolic techniques (spectroscopy, SPECT, PET in particular).

Malignant gliomas: early diagnosis and clinical aspects

Brain tumor symptoms vary greatly from person to person because of two factors: location and size of tumors. The size of a tumor, however, does not necessarily affect the severity of symptoms. Manifestations depend on the cause of the symptoms: an increase in ICP, direct compression of gray or white matter, shifting of intracranial contents, or secondary cerebral ischemia. Symptoms may be non-specific and include headache, altered mental status, ataxia, nausea, vomiting, weakness, and gait disturbance. Left-sided weakness may be seen in a patient with a tumor pressing on the contra-lateral motor strip or speech difficulties may occur if a tumor is in the dominant hemisphere. Up to a third of people report having seizures prior to being diagnosed with a brain tumor. Rarely, brain tumor can present with psychiatric symptoms but without other neurological signs or symptoms. Evaluation for brain tumor is indicated in any patient with chronic, persistent headache associated with protracted nausea, vomiting, seizures, changes in headache pattern, neurologic symptoms, and change in personality.

Methotrexate based chemotherapy and deferred radiotherapy for primary central nervous system lymphoma (PCNSL): single institution experience

In the following study, we present our experience in the treatment of PCNSL patients using a multi-step schedule combining chemotherapy and deferred radiotherapy. Patients were treated with two modified M-BACOD cycles and then differently according to radiological response For PR, SD and PD patients, chemotherapy was interrupted and radiotherapy initiated immediately (45 Gy Whole-brain RT). With CR patients, chemotherapy was continued with a combination of HMTX, VCZ, PCB and HD Ara-C up to a total of nine cycles. In 36 patients suitable for evaluation (2 patients had undergone tumour resection): 69.4% (25 of 36) had a complete response (CR), 19.4% (7 of 36) had a partial response(PR), 8.3% (3 of 36) had stable disease(SD), and 2.7% (one of 36) had progressive disease (PD). The PR, SD and PD patients were immediately treated by radiotherapy. In this cohort of patients, we observed 6 CR, 4 PR and 2 PD, respectively, following radiotherapy. At first relapse, a total of 16 CR patients were treated by radiotherapy for a total dose of 45 Gy. The OS was 42.1 months for the entire group of patients. In CR patients treated at the moment of recurrence by salvage radiotherapy, the TTP (time lasting from histological diagnosis until recurrence of disease before RT) was 28.3 months, with a 43.4% of disease free patients observed at 2 years. The median disease-free time observed after complete response to radiotherapy was 10.5 months. In 16 patients (34%), further progression of disease was observed following radiotherapy. Two patients developed extra-CNS disease in the breast and testis. When taking into account the patients with radiotherapy delayed at recurrence, the OS was 48 months and the survival rates were 70% and 60% at 2 years and 5 years, respectively.

Meningitis following relapsing painful ophthalmoplegia in aspergillus sphenoidal sinusitis: a case report

We report the case of a 58-year-old woman in whom relapsing painful ophthalmoplegia related to a mycetoma of the sphenoid sinus gave origin to meningitis with markedly depressed glucose levels in the cerebrospinal fluid. Surgical exeresis of the mycetoma allowed aetiological diagnosis (aspergillosis) and--together with antimycotic therapy--led to durable clinical response.

Systemic temozolomide combined with loco-regional mitoxantrone in treating recurrent glioblastoma

Twenty-two recurrent GBM patients were enrolled for second tumor debulking with local positioning of a Rickam reservoir, in order to locally deliver chemotherapy with the aim of controlling local tumor recurrence. We designed a protocol using systemic temozolomide (150 mg/sqm days 1-5 every 28) in association with mitoxantrone, delivered through the reservoir (4 mg/day 1-5 every 28) positioned into the area of tumor exeresis. After re-operation a residual tumor mass no larger than 2 cm was identified in 18/22 patients. The patients were treated with monthly cycles of chemotherapy until evolution of the tumor, but in no case for more than 10 cycles. Responses were evaluated by MRI scans performed every 2 months and images assessed according to MacDonald's criteria. Response rate: no complete responses (CR), 5 partial responses (PR), 13 stable disease (SD) and 4 progressive disease (PD) occurred. The median progression-free survival (PFS) and survival time (ST) of the whole group of treated patients was 7 and 11 months, respectively and more than a quarter of the patients survived over 18 months. During the study, the patients' compliance was complete and no dropouts occurred. Hematological toxicity was mild and after repeated local injections only minor neurological side-effects occurred. Despite some bias in patients' selection not excluded in this pilot study, results are interesting: the PFS was as long as the survival of recurrent GBM reported in the literature.

The role of the neurologist

The contribution of the neurologist should focus on timely diagnosis with accurate differential diagnosis, indications for surgery and post-surgical treatment (in the setting of a multidisciplinary team), and follow-up of disease course/treatment-related complications.

Local drug delivery in recurrent malignant gliomas

In recurrent malignant gliomas, we scheduled a protocol by adding to systemic temozolomide a local treatment delivered through a reservoire positioned in the surgically created cavity, consisting of either mitoxantrone, liposome-loaded doxorubicine or nimustine (ACNU). The progression-free survival (PFS) and survival time (ST) of the whole group of 112 patients were 8.3 and 11 months, respectively, in GBM patients, and 14 and 18 months in AA patients. To limit the selection bias in recruitment we matched locally treated patients with the whole group of patients treated for 3 years and having undergone the same protocol with the exception of local drug delivery. Variables such as age, histology and local chemotherapy delivery were proved to be statistically significant independent factors on adjunctive PFS and ST. Another group of 12 recurrent malignant gliomas with further progression was locally managed according to convection-enhanced delivery (CED) of mitoxantrone; the preliminary results show good tolerability of the schedule.

Headache in brain tumours: a symptom to reappraise critically

Headache can be either a late or early symptom of a brain tumour, depending on the location of the tumour. A constant, progressively increasing pain, or a change in the character of headache pain, may alert the physician to this occurrence. Fortunately most people with headache, even persistent or severe headaches, do not have a tumour. In this work we review the literature about prevalence of headache as an isolated/early symptom of brain tumour and report our experience.

New approach in delivering chemotherapy: locoregional treatment for recurrent glioblastoma (rGBM)

The treatment of GBM tumor recurrence is generally a hopeless challenge, since recurred tumor is resistant to the most common therapeutic efforts. Some partial results can be achieved by targeting local disease control, in view of the fact that 95% of recurrences occur locally. We present results concerning three pilot studies, all performed in recurrent GBM patients who underwent second surgery and have been treated systemically with temozolomide and locally through an Ommaya reservoire according to the following schedules: a) in 20 rGBM, 4 mg novantrone was delivered day 1,5 every 30 days; in 26 rGBM, 4 mg novantrone was delivered every 20 days in association with locoregional radioimmunotherapy (RIT); in 12 rGBM pegylated liposomal doxorubicin 4 mg was delivered day 1,5,10,15,20 with 20 days interval. Results seem very promising since there is an extension of disease free and survival, both of more than 50 % if results are evaluated in relation with the most frequent data of the literature.

IL-10 production in multiple sclerosis patients, SLE patients and healthy controls: preliminary findings

IL-10 is a cytokine with suppressive effects on (auto) antigen presentation and T-cell-mediated immune reactions, but is also capable of stimulating polyclonal IgG synthesis. Recent evidence suggests its involvement in multiple sclerosis (MS) and systemic lupus erythematosus (SLE). We assessed PBMNC IL-10 release in MS and SLE patients before and after in vivo prednisone or methylprednisolone treatment. The SLE patients showed a high level of IL-10 release by unstimulated PBMNCs, whereas the PHA-stimulated PBMNCs from MS patients produced large amounts of the cytokine.

Spinal cord involvement and systemic lupus erythematosus: clinical and magnetic resonance findings in 5 patients

We report the clinical, magnetic resonance imaging (MRI) and laboratory findings in 5 patients with clinical spinal cord involvement with an acute or subacute course; in two of the patients the myelitic episode preceded, in one it was concomitant to, and in two it followed the diagnosis of systemic lupus erythematosus (SLE). The marked clinical and MRI heterogeneity detected in our patients suggests that various factors may be implied in the pathogenesis of spinal cord involvement in SLE. The possibility of a future evolution to SLE should be kept in mind in women presenting spinal cord involvement with no other explanation, and should be assessed by means of extensive and repeated clinical and laboratory evaluations.

Tremor as an early manifestation of systemic lupus erythematosus

Systemic lupus erythematosus (SLE) has been described by many authors as a multisystem disorder involving variable and protean clinical manifestations and with an unpredictable course. We report the case of a 68-year-old woman suffering from SLE in whom tremor appeared ten years before a clinical picture suggestive of SLE and which remained the only clinical neurological sign even during overt disease. Tremor and other SLE manifestations disappeared with corticosteroid therapy.

Decreased cholesterol biosynthesis in fibroblasts from patients with Parkinson disease

The underlying cause of cellular degeneration in the substantia nigra of patients with Parkinson disease has not been clearly established. With the objective of investigating whether metabolic abnormalities would be detected in peripheral non-neuronal cells, we began assessing key metabolic parameters in skin fibroblasts of these patients. The present report focuses on the finding of a remarkably reduced cholesterol biosynthetic capability of fibroblasts from patients with Parkinson disease. 14C-Acetate incorporation into cholesterol of these fibroblasts was 27.8 +/- 9.4% that observed in normal fibroblasts, and the reduced cholesterol synthesis was confirmed by measuring the activity of the rate-limiting enzyme HMGCoA reductase which averaged 6.64 +/- 2.50 nmol/h/mg protein in the patient's fibroblasts compared to 14.70 +/- 0.69 nmol/h/mg protein in the control fibroblasts. Cholesterol esterifying activity, as cholesteryl oleate formed from 14C-oleate, of the fibroblasts from Parkinson patients, was reduced by an average 43%. Two hypotheses are put forward to link these findings with the current experimental evidences for both increased lipid peroxidation and defective mitochondrial respiratory chain complex I activity in a number of cell types from Parkinson patients. Considering that decreased cholesterol biosynthesis has been detected in all the Parkinson cell lines thus far investigated, it is suggested that this may be a hallmark of the disease.

Growth hormone responses to cholinergically active drugs in patients with dementia of the Alzheimer type

Patients with dementia of the Alzheimer type (DAT) reportedly have reduced concentrations and function of some brain messengers, particularly acetylcholine and somatostatin, not only in the cerebral cortex, but also in subcortical structures, e.g., the hippocampus and the hypothalamus. We wished to determine the responsive pattern of DAT patients to neurohormonal and pharmacologic probes affecting growth hormone (GH) release through an interaction with hypothalamic cholinergic and somatostatinergic (SS) neurons. In 10 DAT patients, pyridostigmine (120 mg orally, p.o.), an inhibitor of acetylcholinesterase, induced an increase in GH levels similar to that elicited by the drug in age-matched controls. In 9 DAT patients, administration of GH-releasing hormone (GHRH, 1 microgram/kg body weight, intravenously, i.v.) induced an increase in plasma GH not different from that evidenced in control subjects. In DAT patients the GHRH-induced GH increase was completely inhibited by pretreatment with atropine (1 mg intramuscularly, i.m., 15 min before administration of GHRH). These findings are considered to indicate that in DAT patients, hypothalamic cholinergic and somatostatinergic neurons involved in control of somatotropic function are preserved.
