Objective:To analyze the diagnostic value of metabolic makers in cerebrospinal fluid in advanced lung adenocarcinoma patients with leptomeningeal metastases (LM) .Methods:A total of 46 cerebrospinal fluid samples (LM group) from lung adenocarcinoma patients with LM admitted to Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from December 2019 to December 2021 were collected, and 48 cerebrospinal fluid samples (control group) from patients with benign neurological diseases during the same period were collected. Metabolomics analysis of cerebrospinal fluid was carried out by high-performance liquid chromatography-mass spectrometry. Principle component analysis (PCA) and orthogonal to partial least squares discriminant analysis (OPLS-DA) were used for modeling. Multi-criteria assessment was used to identify the different metabolites between the two groups. Receiver operating characteristic (ROC) curve, pathway enrichment analysis and other methods were used to screen metabolites and pathways related to LM from lung adenocarcinoma.Results:There were no statistically significant differences in the proportions of age ( Z=-0.41, P=0.210) , gender ( χ2=1.19, P=0.275) , history of smoking ( χ2=2.86, P=0.091) , Karnofsky performance status score ( χ2=0.65, P=0.419) and increased intracranial pressure ( χ2=0.65, P=0.419) between the LM group and control group. The models of PCA (R2X was 0.608 and 0.583, Q2 was 0.462 and 0.513 in electrospray ion positive and negative modes, respectively) and OPLS-DA (R2Y was 0.967 and 0.889, Q2 was 0.959 and 0.852 in electrospray ion positive and negative modes, respectively) showed that the overall data quality was good. Meanwhile, the model interpretation rate and prediction rate were effective. The permutation tests duplicated for 200 times and showed no over-fitting of the established model. The metabolic profiles of the two groups were significantly different. A total of 30 endogenously differential metabolites were screened by using multi-criteria assessment. Six potential biomarkers with larger area under the curve (AUC) were identified through ROC curve analysis, including tyrosine (AUC=0.967, 95% CI: 0.906-1.000) , phenylalanine (AUC=0.992, 95% CI: 0.973-1.000) , pyruvate (AUC=0.976, 95% CI: 0.935-1.000) , tryptophan (AUC=0.935, 95% CI: 0.880-0.973) , glucose (AUC=0.932, 95% CI: 0.880-0.975) and adenosine monophosphate (AUC=0.993, 95% CI: 0.987-1.000) . The 30 selected differential metabolites were enriched and analyzed for metabolic pathways, and 20 relevant metabolic pathways were matched. Among them, the four metabolic pathways most likely to cause changes in metabolites were glycolysis and glucose metabolic synthesis, pyruvate metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis. Conclusion:Untargeted metabolomics analysis can effectively screen specific cerebrospinal fluid metabolites in lung adenocarcinoma patients with LM. Six potential metabolites such as tyrosine, phenylalanine, pyruvate, tryptophan, adenosine monophosphate, glucose and their metabolic pathways may be involved in the pathogenesis of LM from lung adenocarcinoma.

Objective:To investigate the pharmacokinetics of cerebrospinal fluid pemetrexed following intrathecal injection chemotherapy in patients with leptomeningeal metastasis (LM) from lung adenocarcinoma and provide a basis for clinical intrathecal injection chemotherapy.Methods:A total of 21 patients with lung adenocarcinoma LM who underwent pemetrexed intrathecal injection chemotherapy via Ommaya capsule at Nanjing Drum Tower Hospital, Aiffilitated Hospital of Nanjing University Medical School from November 2019 to November 2022 were collected, and divided into 30, 40 and 50 mg groups ( n=10, n=4, n=7) according to pemetrexed dose. Cerebrospinal fluid was collected at 0, 0.5, 1, 2, 4, 6, 12, 24 and 48 h after the first intrathecal injection chemotherapy, and day 8 of each cycle for three groups. Reversed phase high performance liquid chromatography was used to determine the drug concentration in cerebrospinal fluid, to clarify the drug-related pharmacokinetic parameters, and to compare the differences in pemetrexed concentration among groups. Finally, cerebrospinal fluid pemetrexed concentration changes were observed and compared after different intrathecal injection chemotherapy cycles. Results:There were statistically significant differences in cerebrospinal fluid drug concentrations of patients in three groups at 0, 0.5, 1, 2, 4, 6, 12, 24 and 48 h after the first intrathecal injection chemotherapy (30 mg group: F=20.56, P<0.001; 40 mg group: F=27.06, P<0.001; 50 mg group: F=28.63, P<0.001), and there were statistically significant differences in the concentration of cerebrospinal fluid drugs in each dose group at 0.5, 1, 2, 4, 6 and 12 h compared to 0 h after intrathecal injection chemotherapy (all P<0.05). Compared to the 30 mg group, cerebrospinal fluid drug concentrations in the 50 mg group increased at 1, 2, 4, 6, 12 and 24 h after intrathecal injection chemotherapy, with statistically significant differences (all P<0.05). Pharmacokinetic analysis of cerebrospinal fluid pemetrexed showed that area under the concentration-time curve (AUC) 0-∞ of the 30, 40 and 50 mg groups were (5 696.12±283.32), (7 886.29±396.57), and (14 202.70±440.19) h·mg/L, respectively, with a statistically significant difference ( F=1 159.00, P<0.001) ; AUC 0-∞ increased in the 50 mg group compared to the 30 and 40 mg groups (both P<0.05) ; AUC 0-∞ increased in the 40 mg group compared to the 30 mg group ( P<0.05). The half-lives of three groups were (8.75±0.23), (11.29±0.59) and (16.42±1.23) h, respectively, with a statistically significant difference ( F=206.80, P<0.001) ; half-life was longer in the 50 mg group compared to the 30 and 40 mg groups (both P<0.05) ; half-life was longer in the 40 mg group compared to the 30 mg group ( P<0.05). The peak time of three groups were (1.55±0.10), (1.00±0.01), (1.43±0.11) h, respectively, with a statistically significant difference ( F=48.11, P<0.001) ; the peak time was shorter in the 40 and 50 mg groups compared to the 30 mg group (both P<0.05). Clearance of three groups were (7.02±2.46), (5.80±1.25) and (3.66±1.32) L/h, respectively, with a statistically significant difference ( F=6.02, P=0.009) ; clearance was decreased in the 50 mg group compared to the 30 mg group ( P<0.05). The peak concentration of three groups were (540.45±32.25), (820.75±46.47) and (1 014.78±64.96) mg/L, respectively, with a statistically significant difference ( F=207.70, P<0.001) ; peak concentration increased in the 50 mg group compared to the 30 and 40 mg groups (both P<0.05) ; peak concentration increased in the 40 mg group compared to the 30 mg group ( P<0.05). Cerebrospinal fluid drug concentrations were dynamically monitored after 4 cycles of intrathecal injection chemotherapy, in which cerebrospinal fluid pemetrexed concentrations in 30 mg group were (13.76±4.79), (11.41±7.08), (9.41±2.59) and (7.86±4.02) mg/L, respectively; 40 mg group were (14.45±6.59), (12.87±15.73), (11.24±2.48) and (9.09±3.38) mg/L, respectively; 50 mg group were (12.94±10.34), (9.72±7.62), (8.15±8.17) and (4.34±4.21) mg/L, respectively. There was a statistically significant difference in cerebrospinal fluid drug concentrations among different intrathecal injection chemotherapy cycles in 30 mg group ( F=4.04, P=0.016), and the cerebrospinal fluid drug concentration decreased in cycles 3 and 4 compared to cycle 1 (both P<0.05). There were no statistically significant differences in cerebrospinal fluid drug concentrations among different treatment cycles in 40 and 50 mg groups ( F=0.28, P=0.837; F=3.57, P=0.066) . Conclusion:Reversed phase high performance liquid chromatography method can effectively detect the pemetrexed concentration in cerebrospinal fluid; dynamic monitoring of cerebrospinal fluid pemetrexed concentration can provide a basis for the dosage and the treatment cycle of intrathecal injection chemotherapy in LM patients with lung adenocarcinoma.

Leptomeningeal metastasis (LM) is one of the most severe complications of non-small-cell lung cancer (NSCLC), and its incidence is increasing gradually with the progress of targeted therapies. There are currently no standard guidelines for the therapy of LM. Intrathecal chemotherapy is the mainstay of treatment for NSCLC patients with LM, but the optimal drug, administration route and mode, and dosage remain unclear. We report a case of LM from NSCLC, who received the intrathecal chemotherapy with pemetrexed by Ommaya reservoir after prior targeted therapies. This local treatment improved the quality of life, and obtained the clearing of CSF cytology and stable lesions of LM without any notable side effects. After confirmation of LM, the patient has survived 17 months until now. Here we report the first case to demonstrate the potential effectiveness of intrathecal pemetrexed by Ommaya reservoir for the treatment of LM of NSCLC, summarize the safety and effectiveness of intrathecal chemotherapy in combination with related literatures, and provide a new strategy for local treatment of LM in clinical.

BACKGROUND:
Tumor markers (TM) in cerebrospinal fluid (CSF) are useful for diagnosing leptomeningeal metastasis (LM). It has not been fully exploited the diagnostic possibilities of the CSF levels since the basic fact that the TM concentration of CSF depends strongly upon the serum levels as well as upon the condition of the blood brain barrier (BBB). To analyze the intrathecal TM synthesis and evaluate the integrity of BBB can be helpful for the definitive diagnosis of LM. Therefore, the aim of this study was to further explore the clinical value of intrathecal TM synthesis and BBB in the diagnosis for the lung cancer patients with LM.
METHODS:
Twenty-five lung cancer patients with LM and 57 patients with nonmalignant neurological diseases (NMNDs) admitted to Nanjing Drum Tower Hospital from December 2016 to March 2020 were included. We compared the integrity of BBB and intrathecal TM synthesis between two groups, analyzed the correlation of CSF TM between the detection and intrathecal synthesis, and evaluated serial CSF cytology, the integrity of BBB and intrathecal TM synthesis when intrathecal chemotherapy for one patient.
RESULTS:
Ninety-four percent LM patients showed the dysfunction of BBB, and all LM patients showed at least one intrathecal synthesized TM in CSF. In one patient, the CSF cytology was negative for the first time, but LM was eventually diagnosed based on the the intrathecal TM synthesis and positive CSF cytology of repeated lumbar puncture. In LM group, no correlation was observed between the detection and intrathecal synthesized TM in CSF. In the control group, only 3.5% (2/57) NMNDs patients had the dysfunction of BBB and no patients had intrathecal TM synthesis, both the differences of which were statistically significant (P<0.05). Finally, evaluating the CSF cytology, integrity of BBB and intrathecal TM synthesis can be used to assess the intracranial treatment effect. Moreover, intrathecal TM synthesis changes earlier than cytology.
CONCLUSIONS
The evaluation of intrathecal TM synthesis and integrity of BBB are novel clinical diagnostic tools. In addition, serial measurement of intrathecal synthesized TM may play an important role in monitoring efficacy of lung cancer patients with LM, which is worthy of further promotion and clinical application.
