RESUMO
PURPOSE: To evaluate adherence (as measured by the medication possession ratio) to the first ever course of oral antineoplasic treatment in cancer patients before and after the implementation of a multidisciplinary consultation program (involving an oncologist, a pharmacist, and a nurse) and to investigate the program's impact on adverse events and drug-related problems. PATIENTS AND METHODS: In a retrospective single-center study, we compared the medication possession ratio 2 months after treatment initiation in a control group (before multidisciplinary consultation program implementation) versus an interventional group (after multidisciplinary consultation program implementation). RESULTS: Two months after oral antineoplasic treatment initiation, the mean ± standard deviation medication possession ratio did not differ significantly when comparing the interventional (multidisciplinary consultation program) group (n = 33; 0.99 ± 0.06) with the control group (n = 64; 0.94 ± 0.16) (p = 0.062). Patients in the multidisciplinary consultation program group had fewer adverse events in general (41, vs 109 in the control group; p = 0.048) and digestive adverse events in particular (6 vs 29, respectively; p = 0.007). A total of 53 and 40 drug-related problems were identified in the control and multidisciplinary consultation program groups, respectively (p = 0.074). CONCLUSIONS: Implementation of an multidisciplinary consultation program was not associated with a significant difference in drug adherence (as assessed by the medication possession ratio), which was good before and after implementation. The multidisciplinary consultation program was associated with a lower incidence of adverse events.

PURPOSE: Meningiomas represent the most frequent tumor of the central nervous system in adults. While most meningiomas are efficiently treated by surgery and radiotherapy/radiosurgery, there is a small portion of radiation- and surgery-refractory tumors for which there is no clear recommendation for optimal management. The French National Tumor Board Meeting on Meningiomas (NTBM) offers a glimpse on the current management of such patients. METHODS: We retrospectively reviewed the charts of patients presented to the multidisciplinary Meeting between 2016 and 2019. We selected patients with a progressive disease after at least two treatments, including surgery and radiotherapy. RESULTS: In this multicentric cohort of 86 cases, patients harbored 17 (19.8%) WHO Grade I, 48 (55.8%) WHO Grade II and 21 (24.4%) WHO Grade III tumors. The median number of treatments received before inclusion was 3 (range: 2 - 11). Following the Board Meeting, 32 patients (37.2%) received chemotherapy, 11 (12.8%) surgery, 17 (19.8%) radiotherapy, 14 (16.3%) watchful observation and 12 (13.9%) palliative care. After a mean follow-up of 13 months post-inclusion, 32 patients (37.2%) had died from their disease. The mean progression free survival was 27 months after radiotherapy, 10 months after surgery, 8.5 months after chemotherapy (Bevacizumab: 9 months - Octreotide/Everolimus: 8 months). CONCLUSIONS: Surgery- and radiation-refractory meningiomas represent a heterogeneous group of tumors with a majority of WHO Grade II cases. If re-irradiation and redo-surgery are not possible, bevacizumab and octreotide-everolimus appear as a valuable option in heavily pre-treated patients considering the current EANO guidelines.

PURPOSE: Complementary and alternative medicine (CAM) use increases in cancer patients, including adult patients with diffuse gliomas. METHODS: Questionnaires addressing CAM use were distributed to adult patients with gliomas of WHO grades II-IV and ECOG performance score of 0-2 during hospital visits and filled in anonymously. The study was conducted in nine centers in France from May 2017 to May 2018. Descriptive cohort analyses and comparative analyses according to gender, age, WHO grade, and recurrent versus newly diagnosed disease were conducted. RESULTS: Two hundred twenty-seven questionnaires were collected; 135 patients (59%) were male. Median age was 48 years, 105 patients (46%) declared having glioblastoma, 99 patients (43%) declared having recurrent disease. Hundred-three patients (45%) had modified their alimentary habits after the glioma diagnosis. At the time of the questionnaire, 100 patients (44%) were on complementary treatment, mainly vitamins and food supplements, and 73 patients (32%) used alternative medicine approaches, mainly magnetism and acupuncture. In total, 154 patients (68%) declared using at least one of these approaches. Expenditures exceeding 100 per month were reported by users in 14% for modification of alimentary habits, in 25% for complementary treatment, and in 18% for alternative medicines. All approaches were commonly considered as improving quality of life and experienced as efficient, notably those associated with more expenditures. CONCLUSIONS: CAM are frequently used by glioma patients in France. Underlying needs and expectations, as well as potential interactions with tumor-specific treatments, and financial and quality of life burden, should be discussed with patients and caregivers.

BACKGROUND: Epidermal growth factor receptor (EGFR) gene alterations and amplification are frequently reported in cases of glioblastoma (GBM). However, EGFR-activating mutations that confer proven sensitivity to tyrosine kinase inhibitors (TKIs) in lung cancer have not yet been reported in GBM. CASE PRESENTATION: Using next-generation sequencing, array comparative genomic hybridization and droplet digital PCR, we identified the p.L861Q EGFR mutation in a case of GBM for the first time. The mutation was associated with gene amplification. L861Q may be a clinically valuable mutation because it is known to sensitize non-small-cell lung cancers to treatment with the second-generation EGFR TKI afatinib in particular. Furthermore, we used slice culture of the patient's GBM explant to evaluate the tumour's sensitivity to various EGFR-targeting drugs. Our results suggested that the tumour was not intrinsically sensitive to these drugs. CONCLUSIONS: Our results highlight (i) the value of comprehensive genomic analyses for identifying patient-specific, targetable alterations, and (ii) the need to combine genomic analyses with functional assays, such as tumour-derived slice cultures.

Cognitive impairment has been reported in 27-83 % of adults with World Health Organization (WHO) grade I-III glioma. However, the few studies in this field used different methods for cognitive assessment. The objective of the present study was to establish the prevalence of cognitive impairment in patients with WHO grade I-III primary brain tumors and determine the effect sizes of a comprehensive battery of tests. This study used a comprehensive neuropsychological battery to examine 27 patients. To control for false positives, prevalence was estimated from the overall neuropsychological score. Size effects were determined using Cohen's d. Cognitive impairment was observed in 51.9 % (95 % CI 33-70.7 %) of the patients; the impairment affected action speed (38.5 %), cognitive (33 %) and behavioral (21.7 %) executive functions, oral expression (29.6 %), episodic memory (29.6 %) and visuoconstructive abilities (19.2 %). The largest effect sizes (d ≥ 1.645) were observed for the Digit Symbol Substitution test, global hypoactivity, free recall, Stroop time, the Boston Naming test (BNT), the Trail Making test B (TMTB), verbal fluency and the Rey-Osterrieth Complex Figure Test. Four of these scores (global hypoactivity, the Digit Symbol Substitution test, the TMTB perseveration, and the BNT) were combined to make a shortened battery (AUC 0.872; 95 % CI 0.795-0.949). The overall neuropsychological score was the sole factor associated with the functional outcome. Our results suggest that about half of survivors with a grade I-III primary brain tumor suffer from cognitive impairment. Tests with a large effect size should be included in future large-scale studies.

BACKGROUND: Incidence and characteristics of pseudoprogression in isocitrate dehydrogenase-mutant high-grade gliomas (IDHmt HGG) remain to be specifically described. METHODS: We analyzed pseudoprogression characteristics and explored the possibility of pseudoprogression misdiagnosis in IDHmt HGG patients, treated with radiotherapy (RT) (with or without chemotherapy [CT]), included in the French POLA network. Pseudoprogression was analyzed in patients with MRI available for review (reference cohort, nâ =â 200). Pseudoprogression misdiagnosis was estimated in this cohort and in an independent cohort (control cohort, nâ =â 543) based on progression-free survival before and after first progression. RESULTS: In the reference cohort, 38 patients (19%) presented a pseudoprogression after a median time of 10.5 months after RT. Pseudoprogression characteristics were similar across IDHmt HGG subtypes. In most patients, it consisted of the appearance of one or several infracentimetric, asymptomatic, contrast-enhanced lesions occurring within 2 years after RT. The only factor associated with pseudoprogression occurrence was adjuvant PCV CT. Among patients considered as having a first true progression, 7 out of 41 (17%) in the reference cohort and 35 out of 203 (17%) in the control cohort were retrospectively suspected to have a misdiagnosed pseudoprogression. Patients with a misdiagnosed pseudoprogression were characterized by a time to event and an outcome similar to that of patients with a pseudoprogression but presented with larger and more symptomatic lesions. CONCLUSION: In patients with an IDHmt HGG, pseudoprogression occurs later than in IDH-wildtype glioblastomas and seems not only frequent but also frequently misdiagnosed. Within the first 2 years after RT, the possibility of a pseudoprogression should be carefully considered.

BACKGROUND: Intracranial solitary fibrous tumour (iSFT) is an exceptional mesenchymal tumour with high recurrence rates. We aimed to analyse the clinical outcomes of newly diagnosed and recurrent iSFTs. METHODS: We carried out a French retrospective multicentre (n = 16) study of histologically proven iSFT cases. Univariate and multivariate Cox models were used to estimate the prognosis value of the age, location, size, WHO grade, and surgical extent on overall survival (OS), progression-free survival (PFS), and local recurrence-free survival (LRFS). RESULTS: Eighty-eight patients were included with a median age of 54.5 years. New iSFT cases were treated with gross tumour resection (GTR) (n = 75) or subtotal resection (STR) (n = 9) and postoperative radiotherapy (PORT) (n = 32, 57%). The median follow-up time was 7 years. The median OS, PFS, and LRFS were 13 years, 7 years, and 7 years, respectively. Forty-two patients experienced recurrence. Extracranial metastasis occurred in 16 patients. Median OS and PFS after the first recurrence were 6 years and 15.4 months, respectively. A higher histological grade was a prognosis factor for PFS (p = 0.04) and LRFS (p = 0.03). GTR influenced LRFS (p = 0.03). CONCLUSION: GTR provided benefits as a first treatment for iSFTs. However, approximately 40% of patients experienced relapse, which remains a challenging state.
RESUMO
BACKGROUND: Atypical meningioma is a variant of meningioma with a high risk of recurrence. Gross total resection is the standard of treatment, while no consensus on optimal adjuvant management has been found. METHODS: Between 2008 and 2018, a retrospective search identified 216 grade II meningiomas treated in six centers. Clinical, histological, and therapeutic data were analyzed to determine the prognostic factors of recurrence and survival. RESULTS: In total, 216 patients underwent surgical resection. Among these, 122 patients (56%) underwent gross total resection, and 21% of the patients received adjuvant radiotherapy. Univariate analysis reported subtotal resection, high Ki-67, negative progesterone receptor (PR) and histological grade evolution as unfavorable prognosis factors. According to multivariate analysis, the Ki-67 proliferative index (cut-off value of 17.5%) was the only prognostic factor of recurrence (HR 1.1; 95% CI, 1.0-1.2, P=0.048). Gross total resection improved progression-free survival (PFS) (P=0.03) but without impact on overall survival (OS) (P=0.2). Median PFS and OS times were longer for patients receiving adjuvant radiotherapy than those who did not receive adjuvant radiotherapy. PFS (P=0.3) and OS (P=0.7) were associated with adjuvant RT by trend only. After a median follow-up time of 6.7 years, 99 (46%) patients relapsed. Median progression-free and OS rates were 4.5 (95% CI, 3.5-5.5) and 14.7 years (11.4-NA), respectively. CONCLUSIONS: In this study, Ki-67 proliferative index was significantly associated with recurrence. Gross total resection significantly improved PFS without impacting OS. Adjuvant radiotherapy delayed recurrence and improved OS, but a longer follow-up time is needed to distinguish a statistically significant difference. Large prospective studies are needed to determine postoperative treatment guidelines.

Integrin α5ß1 was suggested to be involved in glioblastoma (GBM) aggressiveness and treatment resistance through preclinical studies and genomic analysis in patients. However, further protein expression data are still required to confirm this hypothesis. In the present study, we investigated by immunofluorescence the expression of integrin α5 and its prognostic impact in a glioblastoma series of patients scheduled to undergo the Stupp protocol as first-line treatment for GBM. The integrin α5 protein expression level was estimated in each tumor by the mean fluorescence intensity (MFI) and allowed us to identify two subpopulations showing either a high or low expression level. The distribution of patients in both subpopulations was not significantly different according to age, gender, recursive partitioning analysis (RPA) prognostic score, molecular markers or surgical and medical treatment. A high integrin α5 protein expression level was associated with a high risk of recurrence (HR = 1.696, 95% CI 1.031-2.792, p = 0.0377) and reduced overall survival (OS), even more significant in patients who completed the Stupp protocol (median OS: 15.6 vs. 22.8 months; HR = 2.324; 95% CI 1.168-4.621, p = 0.0162). In multivariate analysis, a high integrin α5 protein expression level was confirmed as an independent prognostic factor in the subpopulation of patients who completed the temozolomide-based first-line treatment for predicting OS over age, extent of surgery, RPA score and O-6-methylguanine-DNA methyltransferase (MGMT) promoter methylation (p = 0.029). In summary, for the first time, our study validates that a high integrin α5 protein expression level is associated with poor prognosis in GBM and confirms its potential as a therapeutic target implicated in the Stupp protocol resistance.
RESUMO
A number of neurotoxicity associated with oncological treatments has been reported in non-central nervous system cancers. An expert group presents the state of the art and a guide to help the choice of appropriated tools to assess patient cognition in studies on oncology and neurobehavior in animal models. In addition, current cognitive rehabilitation programs currently under evaluation are also discussed. Cognitive assessments in oncology depend on the research question, study design, cognitive domains, patients' characteristics, psychometric properties of the tests, and whether the tests are supervised or not by a neuropsychologist. Batteries of electronic tests can be proposed, but several of them are characterized by weak psychometric developments. In order to improve the comprehension on the impact of cancer treatments on cognition, new animal models are in development, and would in the future include non-human primate models. By bringing together the skills and practices of oncologists, neurologists, neuropsychologists, neuroscientists, we propose a series of specific tools and tests that accompany the cognitive management of non-CNS cancer patients.

Background. New approaches are needed for patients newly diagnosed with bulky glioblastoma (GB) and/or with severe neurological impairment that cannot benefit from first line temozolomide (TMZ)-based chemoradiotherapy. Bevacizumab (BEV), an antiangiogenic anti-VEGF-R monoclonal antibody, has a rapid impact on tumor-related brain edema in recurrent GB. The present study reports the feasibility and efficacy of an induction treatment with TMZ and BEV to alleviate the initial neurological impairment and/or to reduce the tumor volume before a delayed chemoradiotherapy. Methods. We retrospectively analyzed tumor and target volumes and clinical neurological status in 39 patients with bulky GB and/or with severe neurological impairment after an induction treatment combining TMZ and BEV. Neurological and radiological responses were assessed according to RANO criteria. Calculating gross tumor and clinical target volumes (GTV and CTV) was done at diagnosis and before radiotherapy. Progression-free survival (PFS) and overall survival (OS) were determined by Kaplan Meier methods. Safety was reported according to NCTCAE. Results. A cohort of 39 patients was analyzed between December 2010 and April 2014. Upfront standard TMZ-based chemoradiotherapy was recused due either to tumor volume or impairment of neurological status and/or performance status. After TMZ/BEV induction (median time of 3 months), 6 (15%) patients achieved a partial response (PR), and 17 (44%) had a stable disease. 24 patients (62%) received a radical-intent chemoradiotherapy. TMZ-BEV induced median reduction of the clinical target volume (CTV) was 25.9% [-84.4%; - 4.8%]. The median PFS and OS were 8.4 months [95% CI: (6.6 - 9.9)] and 11.0 months [95% CI: (9.3 - 13.7)], respectively in the whole cohort and 10.8 [95% CI: (9.3 - 12.9)] and 15.0 [95% CI: (13.2 - 17.8)] for irradiated patients. Induction treatment led to corticosteroid dose reduction or cessation in 21 patients (54%). KPS improvement was observed in 38% of patients. Toxicity was mild with only 7/39 (18%) grade III-IV toxicity, including 1 digestive bleeding and 1 epistaxis. Conclusion. TMZ-BEV induction led to CTV reduction allowing for optimal chemoradiotherapy in a majority (62%) of patients for which radiotherapy was initially recused. A clinical benefit was obtained with improved KPS and a decrease in steroid dose.
RESUMO
There is no effective treatment for recurrent glioblastoma (GB) when temozolomide-based radiochemotherapy fails. In theory, intra-arterial (IA) delivery of cytotoxic agents could achieve higher drug concentrations in tumors compared to intravenous injection. Moreover, choosing a highly lipid-soluble drug could make the most of the first-pass effect. Here, we evaluated idarubicin (IDA), a lipophilic anthracycline, in an in vitro assay using four human GB cell lines and compared it with 11 other drugs previously used for the IA treatment of brain tumors. Despite impressive in vitro cytotoxicity, IA IDA did not produce a beneficial effect in 2 patients with recurrent GB.
RESUMO
Cancer-related thrombotic microangiopathy (TMA) is a rare entity whose clinical and biological characteristics have been described in various tumors. Here we describe the first case of cancer-related TMA revealing diffuse bone metastases from an ethmoid sinus carcinoma.
RESUMO
Chordoma is a rare malignant axial tumour that develops from embryonic remnants of the notochord. Surgery and irradiation are the standard initial treatment. However, local recurrence is frequent and cytotoxic chemotherapy is inefficient. Transient activity of imatinib, a platelet-derived growth factor receptor inhibitor, was described in a phase II study. Activity of epidermal growth factor receptor (EGFR) inhibitors (erlotinib, gefitinib) has also been shown in a few recent case reports. We describe a 68-year-old female in whom clivus chordoma recurred after surgery and radiotherapy. The tumour progressed despite imatinib treatment. A partial and sustained response (28+ months) was obtained using erlotinib, an EGFR inhibitor. Erlotinib should be evaluated in a prospective trial investigating new potential therapies against recurrent chordoma.
RESUMO
Ifosfamide is used in the treatment of sarcomas and other tumors. It sometimes provokes encephalopathy, which is a serious complication even if it is usually reversible within 48-72 h after drug cessation. Ifosfamide is required to be activated by hepatic cytochrome P450 (CYP), especially the 3A4 subtype, leading to 4-hydroxy-ifosfamide. Ifosfamide is also converted by CYP3A4 to inactive but neurotoxic metabolites. Aprepitant is a neurokinin-1 receptor antagonist that is a potent antiemetic used in combination with 5-HT3 antagonists and corticosteroids. Aprepitant has an inhibitory effect, as well as a possible inductive effect, on CYP3A4. Since ifosfamide and aprepitant are both substrates of CYP3A4, a pharmacokinetic interaction could result in secondary effects such as the potentialization of neurological side effects. In this report, we describe 2 cases of fatal encephalopathy in patients who have received both ifosfamide and aprepitant, and we discuss the mechanisms that could be involved. Our observations draw attention to the fact that aprepitant must be avoided, or at least used with caution, in patients who are receiving ifosfamide due to the risk of severe neurological side effects.
RESUMO
Unresectable glioblastomas with severe neurological impairment at diagnosis have a poor prognosis. The conventional approach using a temozolomide-based chemoradiotherapy has limited efficiency on patients in the RTOG RPA V-VI classes. The activity of the antiangiogenic monoclonal antibody bevacizumab is well defined in recurrent glioblastoma, despite the fact that its impact on survival is not yet established. We wondered if neoadjuvant bevacizumab, used as upfront treatment in combination with a cytotoxic agent, was tolerable and active on neurological signs in patients with severe alteration of the neurological status due to the tumor being located in functional areas. Eight patients received intravenous bevacizumab, 10 mg/kg every 2 weeks, and either oral temozolomide (150-200 mg/m(2)/day for 5 days every 4 weeks) or intravenous fotemustine (80 mg/m(2) every 2 weeks). After an average of 5 cycles of bevacizumab, a clinical improvement of neurological functions was recorded in 8/8 patients who could then receive radiotherapy at a conventional dose (60 Gy in 30 fractions) with continuation of bevacizumab and the cytotoxic agent. Four out of the 8 patients benefited from a durable stabilization and experienced an unusually long survival in such a bad situation at diagnosis. In conclusion, neoadjuvant bevacizumab with chemotherapy appears to be feasible and efficient in a category of patients from the RTOG RPA V-VI classes, by allowing the completion of full-dose radiotherapy. A clinical trial is planned to confirm these retrospective observations.
RESUMO
BACKGROUND: The purpose of this study was to determine whether the National Institutes of Health Stroke Scale (NIHSS) score was associated with inhospital neurological and medical complications (NMC) in patients with posterior circulation infarction. METHODS: This retrospective study included all patients admitted to our stroke unit during a one-year period (n = 289). NMC included neurological deterioration (ie, worsening by 4 points or more of the NIHSS score during the hospital stay) and all other medical complications based on what was recorded in the patients' charts. RESULTS: Seventy-nine patients (27%) experienced NMC. In posterior circulation infarction patients (n = 90), patients with NMC had a higher baseline NIHSS score (10.9 versus 2.2, P = 0.004) and a baseline NIHSS score >2 (78% versus 36%, P = 0.003). In stepwise logistic regression, an NIHSS score >2 (odds ratio: 8.2; 95% confidence interval: 1.64-41.0; P = 0.01) was associated with NMC. Similar results were observed for anterior circulation infarction patients but with a higher cutoff value for NIHSS score. CONCLUSION: In ischemic stroke patients, an increased baseline NIHSS score was associated with an increased risk of NMC. This association applied to anterior-circulation as well as posterior circulation stroke, although zero on the NIHSS for posterior circulation stroke does not mean the absence of NMC during hospitalization. The clinical significance of these findings requires further evaluation in larger prospective studies.
