Objective: The interaction between pregnancy and diffuse low-grade glioma (DLGG) is poorly investigated. The goal of this study was to provide further insights into the relationship between pregnancy and DLGG. Methods: A total of 12 patients were selected from a shared database of DLGGs, according to the following inclusion criteria: DLGG diagnosis in post-partum, DLGG recurrence after pregnancy in patients previously operated for DLGG. The extent of surgical resection (EOR) at first surgery were evaluated. All cases were assessed based on the 2016 WHO classification. The tumor growing patter, expresses by preoperative ΔT2T1 MRI index was evaluated. Results: In four cases newly diagnosed DLGG were detected patients in post-partum. Seven women, previously operated for DLGG, experienced pregnancy during the natural history of glioma, and were affected by tumor recurrence after pregnancy. One singular had an incidental LGG not surgically treated, who presented an important tumor growth after pregnancy. Radiological and surgical data were discussed according to literature. Conclusions: Pregnancy does not seem to have an impact on the survival of women with DLGG. The potential role of pregnancy as risk factor in tumor recurrence is described, however, not proven. In this regard, the association between pregnancy and Tumor recurrence is extremely doubtful, and currently attributable to the simple coincidence. Further multicenter molecular investigations are required to better understand the mechanisms by which the pregnancy, in patients with a pervious surgery for DLGG, may influence tumor regrowth in comparison with the natural history of the disease.
