Abstract:

Objective

To investigate the therapeutic effect of ventriculoperitoneal (VP) shunt in the treatment of leptomeningeal metastasis (LM).

Methods

A total of 41 patients with LM admitted to Neurosurgery Department of the Affiliated Tumor Hospital of Guangzhou Medical University from September 2014 to December 2019 were retrospectively analyzed, and the patients were divided into VP surgery group and non-surgery group, and the KPS scores of two groups before and after treatment were compared. The VP surgery group was further divided in to VP combined with chemotherapeutic drugs and non-combined treatment, VP combined with epidermal growth factor receptor-tyosine ki-nase inhibitor (EGFR-TKI) and non-combined treatment. The curative effect before and after different treatment methods were compared. Kaplan Meier method was used to assess the survival rate in each group and survival curve of patients were drawn.

Results

One week after treatment, KPS score of the operation group was significantly higher than that of the non-operation group, the difference was statistically significant (P<0.05). One month after treatment, the remission rate of VP surgery group was 69.6%, which was higher than that of non-surgery group (33.3%), and the difference was statistically significant (P<0.05). The remission rate of VP surgery combined with chemotherapy was 86.7%, which was higher than that of non-combined therapy (37.5%), and the difference was statistically significant (P<0.05). The remission rate of VP combined with EGFR-TKI was 100%, which was higher than that of non-combined treatment (50%), and the difference was statistically significant (P<0.05). The median survival time of 23 VP patients was 38 weeks, which was higher than that of 18 non-operative patients (5 weeks), and the difference was statistically significant (P<0.05). Among VP patients, the median survival time of those treated with combined EGFR-TKI was 57 weeks, which was significantly higher than that of those not treated with combined EGFR-TKI (32 weeks), with a statistically significant difference (P<0.05).

Conclusion

VP surgery can rapidly and reliably reduce intracranial pressure and improve the quality of life of patients with LM. Combined with chemotherapy drugs and targeted drug therapy can further improve the prognosis of patients with LM and prolong the survival time, which is worthy of clinical promotion.
