Neuroendocrine tumors (NET) are a heterogeneous group of neoplasms that arise from neuroendocrine cells and commonly originate in the GI tract, lungs, and pancreas, but can also present in the skull base and paranasal sinuses. While fluorodeoxyglucose positron emission tomography (FDG PET) scans are routinely used in the evaluation of sinonasal malignancies, their limitations in detecting recurrences near the cranium and cervical lymph node metastases in NETs such as olfactory neuroblastoma (ONB) and sinonasal neuroendocrine carcinomas (SNEC) have prompted the search for an alternative imaging modality. Somatostatin receptor 2 (SSTR2) is a membrane-bound G protein expressed in several types of neuroendocrine and neural cells.

Objective: Current treatment for skull base chordomas utilizes both surgical resection and adjuvant radiation, but recent studies have demonstrated evidence that has brought the use of adjuvant radiotherapy into question. Chordomas differ greatly in molecular makeup and proliferation. These factors have led to significant variation in management across providers.

Purpose: Chordomas are rare malignant tumors arising from the embryological notochord that present most frequently in the lumbosacral spine, followed by the skull base, with an overall 1/1,000,000 incidence. These tumors and their treatment significantly affect quality of life (QOL) due to intricate anatomical locations and aggressive treatment regimens. Despite these challenges, there are currently no disease-specific patient-reported outcome (PRO) surveys for chordomas.

Background And Objectives: The impact of prior local therapies, including radiation and surgery, on reconstruction outcomes after endonasal surgery is currently not well known. Reconstruction nuances in the preoperative setting merit further evaluation to avoid potential postoperative complications that can hinder overall tumor management and negatively impact patient outcome. We sought to determine whether prior treatments increase risk of reconstruction-related postoperative morbidity and to evaluate the effectiveness of our current treatment paradigm for skull base reconstruction.

Background: Treatment for dural recurrence of olfactory neuroblastoma (ONB) is not standardized. We assess the outcomes of stereotactic body radiotherapy (SBRT) in this population.

Methods: ONB patients with dural recurrences treated between 2013 and 2022 on a prospective registry were included.

Article Synopsis
  • A global collaborative study reviewed the management and outcomes of malignant skull base tumors, collecting data from 28 institutions involving 3,061 patients.
  • The majority of surgeries utilized an open approach (55%), with endoscopic (36%) and combined techniques (9.6%) being less common, and the overall 5-year survival rates were 65% for overall survival (OS) and 71.7% for disease-specific survival (DSS).
  • Factors such as older age, comorbidities, and the extent of tumor involvement were identified as independent predictors of survival, while adjuvant radiation therapy (RT) emerged as a protective factor in outcomes.

Article Synopsis
  • This study examines the use of expanded endoscopic approaches (EEAs) versus open surgical approaches in treating sinonasal malignancies with skull base involvement, focusing on long-term outcomes like extent of resection, overall survival, and disease progression.
  • The research included 42 patients who underwent EEAs and 54 who had open surgeries, matching them anatomically to better compare results while addressing selection bias in previous studies.
  • Findings showed that the EEA group had fewer complications (14.29%) compared to the open surgery group (33.33%), with no significant difference in the extent of resection or overall survival rates between the two methods.

 Few recent studies have examined neurocognitive functioning (NCF) in patients with sinonasal and nasopharyngeal cancers (NPCs) prior to and following multimodality therapy or the potential differences in NCF by disease variables such as disease site.  The objective of this study is to determine rates of NCF impairments prior to and following multimodality therapy, declines in NCF following radiotherapy (RT), and possible differences in NCF by the disease site.  We conducted a retrospective chart review of 39 patients with sinonasal and NPCs who underwent comprehensive neuropsychological evaluations.

Article Synopsis
  • - The study aimed to evaluate the safety of induction chemotherapy (IC) for patients with sinonasal cancers that have invaded the brain or caused neurological deficits, analyzing data from 460 patients treated at a cancer center from 1992 to 2020.
  • - Out of the 341 patients who received IC, 40 had brain invasion and 31 had neurological deficits; most patients experienced either partial or complete responses to treatment, with notable improvements in neurological symptoms for some.
  • - Notably, none of the patients had to stop treatment due to worsening neurological conditions, indicating that IC was effectively and safely administered without significant complications related to brain involvement or neurological implications.

 It is unclear if the length of the time interval to initiation of adjuvant radiation therapy (RT) after endoscopic endonasal surgery affects reconstruction outcomes. In this study we present our experience with adjuvant RT after endoscopic endonasal procedures, to determine if the time to RT after surgery impacts post-RT reconstruction complication rates.  A retrospective cohort study of 164 patients who underwent endoscopic endonasal surgery between 1998 and 2021 was conducted.

Sinonasal cancer is a heterogeneous orphan disease of diverse histologies, each with distinct clinical, oncologic, and toxicity profiles. Because of the comparative rarity of these cancers, sinonasal cancers are treated as a grouped diagnosis despite their clinical and biological heterogeneity. Multimodality treatment with a combination of surgery, chemotherapy, and/or radiotherapy is the standard-of-care for advanced-stage patients but there are few surveillance or follow-up practice guidelines or formalized survivorship care pathways.
