Glioblastoma(GBM)is one of the most malignant brain tumors with a median overall survival(OS)of 14.6 mo despite treatment with surgery,radiotherapy,and temozolomide(TMZ)[1,2].The survival time for patients with GBM was shown to increase after treatment with a combination of tumor-treating fields,but only to 20.9 mo[3].Leptomeningeal dissemination(LMD)occurs when glioma cells invade the cerebrospinal fluid(CSF)and the leptomeninges.GBM patients with LMD often showed a worse prognosis than those with progression of parenchymal disease and had a median survival of 2-5 mo[4-6].LMD was initially considered a rare complication of gliomas,but the incidence seems to be higher than the estimated rate of 4%,reaching 25% in postmortem neuropathological studies[4,7,8].Recent studies indicated that LMD incidence is increasing,possibly due to the improvement in survival rates and survival time of GBM patients[9,10].Diagnosis of LMD involves either only enhanced magnetic resonance imaging(MRI)or MRI along with positive morphology of CSF cells.
Intrathecal injection of methotrexate(MTX)is a potentially effective method for treating glioma with LMD.Our team found that MTX can inhibit the growth of GBM cells by downregulating the Ras/MAPK/Myc/CD47 signaling pathway[11].However,an intrathecal injection of MTX was insufficient because it is ineffective on tumor cells in the brain parenchyma.Thus,a combined systemic treatment is needed.TMZ and its combination regimen with etoposide combined with a platinum chemotherapy regimen are optional systemic treatments.We used intrathecal MTX in combination with systemic chemotherapy as a treatment regimen for patients with LMD.This study aimed to estimate the clinical outcomes of combination therapy in GBM patients with LMD.
Next morning she sat down beneath the walls of the castle to play with the golden apple, and the first person she saw was the maiden23 with the long nose, who was to have the Prince
This study was approved by the Medical Ethics Committee of Beijing Tiantan Hospital,Capital Medical University.Between January 2012 and December 2019,intrathecal MTX in combination with systemic chemotherapy was administered to 26 patients with GBM with LMD in our institution.The patient cohort had a median age of 43 years(range: 18-61 years).Their GBM diagnosis was confirmed by specialized neuropathologists according to the 2016 World Health Organization classification of brain tumors.
Diagnosis of LMD was performed as explained above.Concomitant chemoradiotherapy followed by adjuvant TMZ chemotherapy was administered according to standard protocols[1,2].
Data on sex,date of birth,date of initial glioma diagnosis,date of LMD diagnosis,Karnofsky Performance Status(KPS)score at LMD diagnosis,molecular pathologic analysis,initial and subsequent LMD treatments,first CSF results after LMD diagnosis,hematological toxicity of treatment,and date of death or last follow-up were collected for each patient.
The grave was bordered with pieces of flower-pots and strewn over with sand; quite at the top they had stuck up half a beer bottle, with the neck upwards7, and that was not at all allegorical
Each treatment cycle lasted for 28 d.MTX was intrathecally injected 2-3 times during each cycle,with a single dose of 10 mg once a week.A TMZ regimen was the first choice until after 6 cycles of TMZ systemic chemotherapy had been completed.A dose of 150-200 mg/m
/d TMZ was administered over 5 d every 28 d.An etoposide and carboplatin(EC)regimen was used in patients in whom the previous TMZ regimen failed in less than 6 mo.Carboplatin AUC5 was administered once every 28 d,and etoposide was administered at 100 mg/m
/d,for 3 d every 28 d.A TMZ and cisplatin(TP)combinatorial regimen was used in patients whose previous TMZ regimen had failed for over 6 mo.Cisplatin was administered at 30 mg/m
/d,3 d every 28 d,and TMZ was administered at 150-200 mg/m
/d,5 d every 28 d.Bevacizumab(BEV)was administered to patients with severe brain edema after they showed poor reactions to conventional brain edema treatment.BEV was administered at 5 mg/kg,1 day every 28 d.Chemotherapy dosage and interval were adjusted according to chemotherapy principles.Either only MRI or MRI along with CSF morphology was reviewed every 2 mo.If the treatments were evaluated as effective,then patients would continue for no more than 8 cycles.If the treatment was ineffective,then the patient was changed to another combined chemotherapy regimen.This process was carried on until either the tumor progressed,the patients gave up treatment,or the patient died.
The time from patients’ initial GBM diagnosis to their death,time from GBM diagnosis to LMD diagnosis,time from LMD diagnosis to death or last follow-up,and OS(recorded until January 1,2021)were evaluated using the Kaplan-Meier method.The comparison between patients’ characteristics was assessed using a log-rank test.Univariate Cox regression models were applied to assess the effect of the covariates of interest on the time-to-event endpoint.A
value of < 0.05 was considered significant for all analyses.All computations were carried out in SPSS 23.0.
Twenty-six patients with GBM developed LMD and were treated at our institution.
And he stared hard at the princess as she clapped her hands with joy and ran up to them, crying, Oh, do let us keep that delicious beast for to-night; it will make such a nice plaything
Among the 26 patients included in the analysis,16(61.5%)were men and 10(38.5%)were women,with a median age of 43 years(range: 16-61 years).Most patients had supratentorial primary tumor locations;only two had infratentorial tumors(in the cerebellum).Total gross resection was carried out for 7 patients’ tumors(26.9%).Eighteen tumors(69.2%)that were within 1 cm of the ventricular system or that had infiltrated the ventricular system were opened during the initial surgery.Tumor samples from all patients were sent for molecular pathology tests,namely immunohistochemistry or next-generation sequencing.The patterns of treatment after GBM diagnosis and before LMD diagnosis are provided in Table 1.
She told the others, and soon all of them were in it, caught up in the approach of Brunswick, looking at the pictures Vingo showed them of his wife and three children. The woman was handsome in a plain way, the children still unformed in the much-handled snapshots.
The median time from GBM surgery to diagnosis of LMD was 9.4 mo(range: 0.7-41.4 mo).One patient(3.8%)was diagnosed with LMD(spinal cord metastasis)at the time of initial GBM diagnosis,and the remaining 25 patients were diagnosed after surgery.
Intrathecal MTX administration combined with systemic chemotherapy is a potentially effective treatment for patients with GBM and LMD,with mild treatment-related side effects.
Twenty-six of these LMD patients had 4 types of clinical symptoms: headache(46.2%),backache(15.4%),lower extremity weakness(11.5%),and visual changes(3.8%).Only 6 patients(23.1%)were asymptomatic upon diagnosis,needing diagnosis to be made through routine examination.With the progress of the disease,most patients appeared to have intracranial hypertension syndrome,severe headache,progressive cognitive impairment,cranial nerve damage,ataxia,and other symptoms of brain and spinal cord injury.The details are presented in Table 2.
All 26 patients underwent a single lumbar puncture for CSF analysis.Only half these samples(13,50%)were positive for malignant cells in the cytologic examination.Twenty-one patients(80.8%)had total CSF protein levels over the normal range.
For both the convenience of intrathecal chemotherapy and to avoid lumbar puncture-related metastasis,20 patients(76.9%)accepted an Ommaya reservoir implant.According to the chemotherapy plan mentioned above,5 patients used TMZ as systemic chemotherapy,8 accepted TMZ+DDP(TP),and 13 were treated with vp-16+CBP(EC).The median number of chemotherapy cycles was 4(range: 1-8).Four patients changed their systemic chemotherapy plan after first-line failure.One patient accepted vemurafenib therapy because of a BRAF mutation.
The significant treatment-related side effects were gastrointestinal toxicity and myelotoxicity.Accordingto the Common Terminology Criteria of Adverse Events version 4.03,24 patients(92.3%)had grade 1-2 gastrointestinal side effects,whereas 19 patients(73.1%)had grade 1-2 myelotoxicity.
At the last follow-up,6 patients were still alive.The median OS for all patients from the date of GBM diagnosis was 27.8 mo.The median survival time from diagnosis of GBM to LMD was 9.4 mo(range: 2-59 mo).The median survival from the diagnosis of LMD was 10.5 mo(Figure 1A).Ten patients showed improvement in neurological symptoms and imaging.The image of a typical case is shown in Figure 2.Eight patients had stable disease,whereas treatment was not effective in the remaining 8 patients.
Roy and I had invested a great deal of time and work into the patio that spring. The flowers and hanging baskets were breathtaking. It was definitely a heavenly place of rest and tranquility. If I can t be still with God in that environment, I can t be still with Him anywhere, I thought. While Roy was talking on the telephone, I slipped out the backdoor and sat down on my favorite patio chair. I closed my eyes and began to pray, counting my many blessings6.
LMD is a lethal outcome among patients with glioma and is showing an increasing incidence rate.It remarkably reduces patients’ OS.Intrathecal MTX combined with systemic chemotherapy is a potentially effective therapy for GBM patients with LMD.KPS > 60,gross resection of the brain tumor,and the Ommaya reservoir implant are positive prognostic factors for patients with LMD.

The image of the evil stepmother occurs frequently in fairy tales. She is associated with jealousy47 and cruelty (Olderr 1986). In masculine psychology48, the stepmother is a symbol of the unconscious in a destructive role (von Franz 1970). The stepmother figure is actually two sided, in that while she has destructive intentions, her actions often lead the protagonist49 into situations that identify and strengthen his or her best qualities.
LMD in patients with GBM is a serious complication with adverse outcomes.There is no consensus on the treatment for LDM.Disease progression or treatment-related complications,such as intrathecal treatment leading to bleeding and infection after ventricular-abdominal shunt,can sometimes lead to fatal results[6,12].Considering the multifocal nature of LMD,surgical treatment is not appropriate.Palliative radiotherapy is the most used treatment that can relieve symptoms and slightly improve survival[13,14].Completed clinical trials have explored the application of a variety of single-use intrathecal chemotherapeutics,including topotecan,MTX,and cytarabine.Although the safety evaluation is satisfactory,none of the single-use drugs have been shown to significantly improve the survival rate of LMD patients[15].Most intrathecal drugs are single use for LMD patients[A1];Scott
[16]reported that concurrent intrathecal MTX and liposomal cytarabine for solid tumors that developed LMD showed a median non-GBM OS of 30.2 wk,thereby demonstrating a possible strategy of multidrug intrathecal chemotherapy.Single-use BEV or BEV in combination with irinotecan showed inconsistent clinical benefits[4,17,18].Targeted therapy can be used in selected cases with sensitive mutations,but it is not widely used due to the insufficient detection or the low sensitivity of glioma mutations[19-21].Although Chimeric Antigen Receptor T-Cell Immunotherapy therapy for IDH wildtype MGMT-methylated GBM combined with LMD has shown encouraging effects and no related side effects[22],it is difficult to find a suitable target.An immunosuppressive microenvironment and subsequent toxicity limits immunotherapy.
Chemotherapy is one of the main treatment methods for brain tumors.Multiple chemotherapeutic regimens have been investigated,both single or combination treatments(TMZ,lomustine,irinotecan,and BEV)[4,17].No significant effect was achieved with the intrathecal injection chemotherapy of different drugs(MTX or cytarabine)[5,23].Based on our team’s previous research on the use of MTX in the treatment of gliomas and on the combined therapeutic effect of chemotherapy on recurrent gliomas,we combined an intrathecal MTX injection with systemic chemotherapy.The results showed that the current OS improved compared to that obtained in previous studies[4-6].To the best of our knowledge,this clinical study has the largest number of patients receiving treatment for GBM and LMD by intrathecal MTX combined with systemic chemotherapy showing good clinical research conclusions.
Previous studies have shown that MGMT promoter methylation status can be used as an indicator for prognosis in newly diagnosed GBM patients.It was also proposed as a risk factor of LMD development in glioma patients[24].The suspected mechanisms include the increase in the survival of patients subjected to MGMT methylation treatment.MGMT status has no correlation with OS for GBM afterLMD diagnosis.Therefore,for patients diagnosed with LMD,MGMT methylation status should not determine whether TMZ treatment should be used.
But little Georgie P. Johnson just wiggled his nose and pretended not to hear, as if he had molasses stuck in his ear. Of fishing he was very fond, why should he fear McFeeglebee s pond?
BEV has been suggested to promote the development of LMD[18],but available data remain conflicting.Considering the high cost of the BEV and the fact that BEV was not approved by the FDA in China until this year,all the patients in this cohort did not use BEV when GBM was first diagnosed.We only used BEV in patients with severe brain edema and in those who did not respond to conventional dehydration treatment.The results showed that the use of BEV had a negative effect on the OS of patients with LMD but had a favorable effect on relieving intracranial hypertension.
Some studies have shown that ventricular opening during surgery or tumor invasion of the ventricle system may be one of the main factors causing LMD[7,25].In our study,18 patients with LMD(69.2%)showed communication with the ventricle at GBM diagnosis,and this result is consistent with what was obtained in other studies.When it comes to the relationship between ventricular opening and OS of LMD patients,there was no significant difference between the two groups,possibly due to the small sample sizes.Further verification is needed.
Ommaya reservoir implants have been widely used to treat LDM in different cancers.It can avoid the injury caused by a lumbar puncture and reduce the corresponding risks.In this study,Ommaya reservoir implant was a positive factor for the OS of LMD patients.In addition to intrathecal MTX administration,we also used the Ommaya reservoir as a simple device for external ventricular drainage at the end stage of the disease,which can sometimes alleviate the symptoms of intracranial hypertension.
To estimate the clinical outcomes of intrathecal MTX combination with systemic therapy in GBM patients with LMD.
In this study,the MRI[A2]abnormalities of the brain and spinal cord were used to diagnose LMD.However,only 13 patients had positive results on a CSF morphological examination.Generally,the CSF morphology test should be combined with another test result,and with CSF flow cytometry if necessary.Considering that our CSF morphology result is a single lumbar puncture test before an intrathecal MTX injection,the presence of false negatives is possible.
The CSF protein content is a clinical characteristic of patients with brain tumors.Of[A3]23 patients,21 showed increased levels of CSF proteins in this study,and the protein content of CSF decreased in effectively treated patients.Therefore,we supposed that CSF protein content can be used as a marker for disease diagnosis and as a treatment efficiency evaluator.
Our results showed that total resection of the brain tumor at initial diagnosis and KPS ≥ 60 at the time of LMD diagnosis are good prognostic factors,and this conclusion is similar to that obtained in other studies[4].
A couple weeks after Marc arrived home to rest, regroup and write for a while, he was back at work-he had been recruited6 to do campaign work. Since I was still making lunch every day for his younger brother, I packed one for Marc, too. Imagine my surprise when I got a call from my 24?year?old son, complaining about his lunch.
In the study,some patients showed improvement in clinical symptoms,and partial remission was observed with imaging.Considering the lack of a unified evaluation standard,it is impossible to evaluate the curative effect.Therefore,this study only takes OS as the main endpoint and evaluation standard of the curative effect.
At length the Vizier suggested going further on to a pond which lay beyond the town, and where he had often seen a variety of creatures, especially storks19, whose grave, dignified20 appearance and constant chatter21 had often attracted his attention
Firstly,this is a single-center retrospective study with a small sample size.Secondly,it is a single-arm study that lacks a control group.Nevertheless,this retrospective study aimed to preliminarily evaluate the efficacy and safety of intrathecal MTX in combination with systemic chemotherapy in GBM patients with LMD.Promising outcomes have been obtained.Based on this result,a prospective study of combination therapy in GBM patients with LMD is ongoing.
Univariate analysis showed that the median OS from the diagnosis of LMD was significantly different between those with KPS > 60 and KPS ≤ 60(16 mo
9 mo,
= 0.002),Ommaya reservoir implant or no implant(15 mo
6 mo,
< 0.001),and gross total resection of the tumor or not[median 24.7,95%CI(15.1,34.3)
10.9,95%CI(8.0,13.7),
= 0.022](Figure 1B-D).MGMT methylation(
= 0.187),communicating with the ventricle at time of GBM diagnosis(
= 0.778),total protein in CSF(
= 0.321),and BEV use(
= 0.085)had no significant outcome association(Table 3).
Glioblastoma(GBM)is one of the most common and aggressive primary malignant brain tumors with severe symptoms and a poor prognosis.Leptomeningeal dissemination(LMD)is a serious complication of GBM that often results in dire outcomes.There is currently no effective treatment.
Looking for a potential effective methods in GBM patients with LMD.
Then play resumed, the next pitch was thrown - and the young man knocked it out of the park. That was the turning point. From then on, he played the game with a new confidence and power that quickly drew the attention of the parent team, and he was called up to the majors.
Now let me tell you a funny thing: one day, father wanted to get up early as usual17, but he wasn t able9 to do that, because he hadn t set18 the alarm19 clock the night before, so when he got20 up, he did21 everything in a hurry. After father left, mother said22 to me mysteriously23, He will come back soon. Why? I was13 greatly24 surprised25. Because today is Sunday, his holiday! Just as mother said, father came26 back home soon, and went to bed again--he was too tired.
A retrospective analysis was conducted using data collected from GBM patients diagnosed with LMD from January 2012 to December 2019 at our institution.Clinical and pathological data were analyzed to explore the clinical outcome of GBM patients with LMD.
Twenty-six patients were enrolled in this study.The median time from GBM diagnosis to LMD development was 9.3 mo(range: 2-59 mo).The median overall survival of LMD patients from diagnosis to after receiving systemic chemotherapy in combination with intrathecal MTX was 10.5 mo(range: 2-59 mo).In the Cox univariate analysis,gross resection of tumor(
= 0.022),Karnofsky Performance Status(KPS)> 60(
= 0.002),and Ommaya reservoir implant(
< 0.001)were correlated with survival.Multivariate analysis showed that KPS > 60(
= 0.037)and Ommaya reservoir implant(
= 0.014)were positive factors correlated with survival.Myelotoxicity and gastrointestinal reactions were the common toxicities of this combination therapy.According to Common Terminology Criteria of Adverse Events 4.03,most of the patients presented with toxicity less than grade 3.
All 26 patients had positive MRI findings.Leptomeningeal tumor enhancement was found in the brain around the contours of the gyri and sulci or in multiple nodular deposits in the subarachnoid space,cerebellar folia,and the cortical surface.When these are observed in the spinal cord as linear or nodular enhancements along the surface,a conclusive diagnosis of LMD can be made.
This retrospective study aimed to preliminarily evaluate the efficacy and safety of intrathecal MTX in combination with systemic chemotherapy in GBM patients with LMD.Promising outcomes have been obtained.Based on this result,a prospective study of combination therapy in GBM patients with LMD is ongoing.
The authors sincerely thank all the patients and their families for their participation in the present study.
Multivariate analysis showed that OS from diagnosis of LMD was positively associated with KPS > 60(
= 0.037)and the Ommaya reservoir implant(
= 0.014)(Table 4).
Kissing him on the forehead, I said my good-byes and started toward the door. Then I suddenly realized something.
