ABSTRACT

Moyamoya is characterized as a non-atherosclerotic and non-inflammatory vasculopathy that leads to progressive stenosis of the intracranial internal carotid arteries as well as the Circle of Willis. While it can be idiopathic (Moyamoya disease) or associated with another condition (Moyamoya syndrome), there is a characteristic 'puff of smoke' sign that can be appreciated on cerebral angiography.

ABSTRACT

Oncolytic viral (OV) therapies are promising novel treatment modalities for cancers refractory to conventional treatment, such as glioblastoma, within the central nervous system (CNS). Although OVs have received regulatory approval for use in the CNS, efficacy is hampered by obstacles related to delivery, under-/over-active immune responses, and the "immune-cold" nature of most CNS malignancies. SUMO, the Small Ubiquitin-like Modifier, is a family of proteins that serve as a high-level regulator of a large variety of key physiologic processes including the host immune response. The SUMO pathway has also been implicated in the pathogenesis of both wild-type viruses and CNS malignancies. As such, the intersection of OV biology with the SUMO pathway makes SUMOtherapeutics particularly interesting as adjuvant therapies for the enhancement of OV efficacy alone and in concert with other immunotherapeutic agents. Accordingly, the authors herein provide: 1) an overview of the SUMO pathway and its role in CNS malignancies; 2) describe the current state of CNS-targeted OVs; and 3) describe the interplay between the SUMO pathway and the viral lifecycle and host immune response.

ABSTRACT

OBJECTIVE: The prognostic impact of intra-operative tumor spillage (ITS) during minimally invasive surgery (MIS) for endometrial cancer (EC) is not well studied. The objective of this study was to determine if there is an association between ITS and EC recurrence. METHODS: We performed a case-control study of patients with a laparoscopic or robot-assisted hysterectomy with EC on final pathology between 2017 and 2022 and compared those with (case) and without (control) a subsequent EC recurrence. Electronic medical records were reviewed for demographic, intra-operative and pathologic details, and recurrence status. ITS was defined as uterine perforation with a manipulator, presence of extra-uterine tumor after colpotomy or specimen delivery, exposure of uncontained specimen into peritoneum, and/or pathology/operative reports noting specimen fragmentation. Conditional logistic regression was used to determine odds ratios for the association of cancer recurrence with ITS. We adjusted for >50% myoinvasion, tumor size, and adjuvant treatment. RESULTS: 1057 patients underwent MIS for EC. Approximately 8% (n = 86) developed recurrent cancer and 172 patients were selected as controls. Twenty percent of recurrent cases (17/86) had ITS compared with 4% of nonrecurrent controls (7/172). When adjusted for tumor size, deep myoinvasion, and adjuvant treatment, patients with ITS had a 5.6 times increased odds (aOR 5.63, 95% CI 1.52-20.86) of recurrence compared to patients without ITS. CONCLUSIONS: In patients with EC, we found an association between ITS and cancer recurrence. These findings warrant further investigation to determine if adjuvant therapy or surgical technique should be altered to improve outcomes.
