Brief Summary

Intrathecal chemotherapy is one of the most important treatment modalities for leptomeningeal metastasis of solid tumors. In the previous retrospective study, it has been proved that concurrent radiotherapy and intrathecal methotrexate for leptomeningeal metastasis from solid tumors with adverse prognostic factors showed great effectiveness and safety. The preliminary results of investigators' current prospective clinical study (Involved-field Radiotherapy Combined With Concurrent Intrathecal-methotrexate Versus Intrathecal-Ara-C for Leptomeningeal Metastases From Solid Tumor: A Randomized Phase II Clinical Trial. ClinicalTrials.gov identification number: NCT03082144) also showed that the regimen of concurrent intrathecal chemotherapy and radiotherapy may serve as an optimal therapeutic option for treatment of leptomeningeal metastases from solid tumors. Pemetrexed is a newer multitargeted antifolate which has shown activity in various tumors. In investigators' current study (Intrathecal Pemetrexed for Recurrent Leptomeningeal Metastasis From Non-small Cell Lung Cancer: A Prospective Pilot Clinical Trial. ClinicalTrials.gov identification number: NCT03101579), the regimen of intrathecal pemetrexed with folic acid and vitamin B12 supplementation may provide higher effectiveness and safety for recurrent leptomeningeal metastasis from non-small cell lung cancer. Therefore, the purpose of the study is to evaluate the tolerability, safety and effectiveness of intrathecal pemetrexed combined with involved-field radiotherapy as the first line treatment in patients with leptomeningeal metastases from malignant solid tumors.

Conditions

Leptomeningeal Metastasis

Keywords

Leptomeningeal metastasis; Malignant solid tumors; Pemetrexed; Intrathecal chemotherapy; Radiotherapy

Outcome Measures

Primary Outcomes (1)

• Incidence of treatment-related adverse events

  The incidence of treatment-related adverse events were measured for determing tolerability and safety. Adverse events (AEs) are evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE, version 4.03). Events of grade 3-5 are defined as moderate and severe adverse events.

  The evaluation was performed at 3 months after the end of treatment or when patient died.

Secondary Outcomes (3)

• Clinical response rate

  The evaluation was performed at 3 months after the end of treatment or when patient died.

• Overall survival

  The evaluation was performed at least 7 months after leptomeningeal metastasis diagnosis or until death.

• Neurological progression-free survival (NPFS)

  All patients were followed up at least 6 months, and the evaluation of NPFS was performed from the beginning of treatment until the date of first documented neurological progression or date of death from any cause, whichever came first.

Study Arms (1)

Group 1,Intra-pemetrexed, radiotherapy

EXPERIMENTAL

The treatment regimen consisted of intrathecal chemotherapy (via lumbar puncture, pemetrexed 10 mg, plus dexamethasone 5 mg, once per week, 5-8 times, 4-7 weeks in total) and radiotherapy. Radiotherapy consisted of fractionated, conformal radiation given at a daily dose of 2 Gy. The planning volume consisted of sites of symptomatic disease, bulky disease observed on magnetic resonance imaging, including the whole brain and basis cranii received 40 Gy in 20 fractions, 4 weeks in total, and/or segment of spinal canal received 40-50 Gy.
