“…Moreover, as concerns tumor recurrence within 12, 24 and 36 months of the surgery, respectively, we noted that larger meningiomas, the tumor volume of which is higher than the mean tumor volume, are more prone to recurrence. This is consistent with literature studies, according to which a larger tumor volume is a prognosis factor for recurrence [34,50,80,[96][97][98][99]. This may be accounted for by the fact that larger tumors pose additional challenges in achieving tumor resection as complete as possible, and consequently, the patient has a higher risk of tumor recurrence.…”

“…However, treatment algorithms have not been well established for OGMs smaller than 3 cm in diameter that demonstrate continued growth in patients who are high surgical risk, particularly older patients with significant comorbidities which may preclude conventional open surgical intervention. Surgical resection of OGMs can also be complicated by their close proximity to critical neurovascular structures [10]. Despite improvements in microsurgical techniques, postoperative complications including anosmia and visual disturbances have been reported at rates as high as 89.7 and 7.7%, respectively [10].…”

Despite improvements in microsurgical techniques, postoperative complications including anosmia and visual disturbances have been reported at rates as high as 89.7 and 7.7%, respectively [10]. Since RT has recently emerged as an effective alternate modality for treatment of primary intracranial diseases particularly in the nonsurgical and elderly populations or as adjuvant therapy for residual or recurrent disease the question arises whether such therapy is a suitable option for patients with OGMs which require treatment.…”

Purpose: To assess the safety and efficacy of CyberKnife® radiotherapy (CKRT) for the treatment of olfactory groove meningiomas (OGMs).Methods: A retrospective review was performed of 13 patients with OGM treated with CKRT from September 2005 to May 2018 at our institution. Nine patients were treated primarily with CKRT, 3 for residual disease following resection, and 1 for disease recurrence.Results: Five patients were treated with stereotactic radiosurgery (SRS), 6 with hypofractionated stereotactic radiotherapy (HSRT), and 2 with fractionated stereotactic radiotherapy (FSRT). The median tumor volume was 8.12 cm 3 . The median prescribed dose was 14.8 Gy for SRS, 27.3 Gy for HSRT, and 50.2 Gy for FSRT. The median maximal dose delivered was 32.27 Gy. Median post treatment follow-up was 48 months. Twelve of 13 patients yielded a 100% regional control rate with a median tumor volume reduction of 31.7%. Six of the 12 patients had reduced tumor volumes while the other 6 had no changes. The thirteenth patient had significant radiation-induced edema requiring surgical decompression. Twelve patients were alive and neurologically stable at the time of the review. One patient died from pneumonia unrelated to his CKRT treatment.Conclusions: CKRT appears to be safe and effective for the treatment of OGMs.

“…Recovery of function may have contributed to these results. Patients with extracerebral tumors, such as frontal meningioma, tend to make good recovery after resective surgery (Fountas et al, 2018;Liouta, Koutsarnakis, Liakos, & Stranjalis, 2016;Tucha et al, 2003), although presurgical deficits may persist (Rijnen et al, 2019). All participants in our OFC lesion cohort were in the chronic phase of recovery (at least 2 years post-tumor resection or trauma).…”

Anticipation, monitoring, and evaluation of the outcome of one's actions are at the core of proactive control. Individuals with lesions to OFC often demonstrate behaviors that indicate a lack of recognition or concern for the negative effects of their actions. Altered action timing has also been reported in these patients. We investigated the role of OFC in predicting and monitoring the sensory outcomes of self-paced actions. We studied patients with focal OFC lesions (n = 15) and healthy controls (n = 20) while they produced actions that infrequently evoked unexpected outcomes. Participants performed a self-paced, random generation task where they repeatedly pressed right and left buttons that were associated with specific sensory outcomes: a 1- and 2-kHz tone, respectively. Occasional unexpected action outcomes occurred (mismatch) that inverted the learned button–tone association (match). We analyzed ERPs to the expected and unexpected outcomes as well as action timing. Neither group showed post-mismatch slowing of button presses, but OFC patients had a higher number of fast button presses, indicating that they were inferior to controls at producing regularly timed actions. Mismatch trials elicited enhanced N2b-P3a responses across groups as indicated by the significant main effect of task condition. Planned within-group analyses showed, however, that patients did not have a significant condition effect, suggesting that the result of the omnibus analysis was driven primarily by the controls. Altogether, our findings indicate that monitoring of action timing and the sensory outcomes of self-paced actions as indexed by ERPs is impacted by OFC damage.
