Neurocognitive Functioning of Patients with Sinonasal and Nasopharyngeal Cancers Treated With Multimodality Therapy.

 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.

Does Time to Initiation of Adjuvant Radiotherapy Affect Reconstruction Outcomes after Endoscopic Resection of Skull Base Malignancies?

 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.

Current status of sinonasal cancer survivorship care.

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.

Predictors of postoperative performance status after surgical management of infratemporal fossa malignancies.

Infratemporal fossa (ITF) tumors are difficult to access surgically due to anatomical constraints. Moreover, aggressive ITF carcinomas and sarcomas necessitate aggressive treatment strategies that, along with tumor-related symptoms, contribute to decreases in patient performance status. To assess factors that predict postoperative performance in patients undergoing surgery for ITF tumors.

Updates in management strategies of locally advanced sinonasal malignancy.

Purpose Of Review: Sinonasal tumors are a rare heterogenous group of pathologies with poor prognosis. In recent years better definition and understanding of histology, molecular classification, biological behavior and advances in therapy have resulted in improved prognosis. The purpose of this review is to give an updated summary of the recent advances in treatment, and where relevant, with references to pathology classifications.

Impact of Clinical Factors and Treatments on SMARCB1 (INI-1)-Deficient Sinonasal Carcinoma.

The objective of this study was to report outcomes for 19 consecutive patients with SMARCB1 (INI-1)-deficient sinonasal carcinoma. Patients were treated from 2014 to 2021 and followed for a median of 22.3 months.

Orbital and periocular complications in patients with sinonasal tumours with orbital invasion.

Aims: The purpose of this study was to determine the frequency and associated risk factors of orbital/periocular complications in patients with sinonasal tumour with orbital invasion managed with eye-sparing treatments.

Methods: A retrospective case series of patients with primary sinonasal tumour with orbital invasion from January 2008 to December 2018. Patient factors were compared between the following groups: (1)patients with orbital/periocular complications versus those who did not and (2) patients who needed secondary oculoplastic surgical procedures versus those who did not.

Impact of Cancer Care Regionalization on Patient Volume.

Background: Cancer centers are regionalizing care to expand patient access, but the effects on patient volume are unknown. This study aimed to compare patient volumes before and after the establishment of head and neck regional care centers (HNRCCs).

Methods: This study analyzed 35,394 unique new patient visits at MD Anderson Cancer Center (MDACC) before and after the creation of HNRCCs.

Patient, Disease, and Treatment-Related Factors Affecting Progression-Free and Disease-Specific Survival in Recurrent Chondrosarcomas of the Skull Base.

Background: Recurrent skull base chondrosarcomas (CSA) are difficult to treat, and limited data are available to help guide subsequent therapy.

Objective: To further characterize the natural history of CSA and identify treatment modalities that were most effective in prolonging progression-free (PFS) and disease-specific survival (DSS).

Methods: We conducted a single-institution retrospective review of patients with recurrent skull base CSA from 1993 to 2021.

Neoadjuvant checkpoint inhibitor immunotherapy for resectable mucosal melanoma.

Background: Neoadjuvant checkpoint inhibition (CPI) has recently demonstrated impressive outcomes in patients with stage 3 cutaneous melanoma. However, the safety, efficacy, and outcome of neoadjuvant CPI in patients with mucosal melanoma (MM) are not well studied as MM is a rare melanoma subtype. CPI such as combination nivolumab and ipilimumab achieves response rates of 37-43% in unresectable or metastatic MM but there is limited data regarding the efficacy of these agents in the preoperative setting.

Soft Tissue Sarcomas of the Head and Neck Region with Skull Base/Intracranial Invasion: Review of Surgical Outcomes and Multimodal Treatment Strategies: A Retrospective Case Series.

Soft tissue sarcomas (STS) invading the skull base are rare with little data to guide surgical management. Here we aimed to determine the factors affecting tumor control rates and survival in patients with T4 stage head and neck STS involving the skull base. A retrospective review of STS patients, surgically treated at our institution between 1994 and 2017 was conducted.

The impact of expanded endoscopic approaches on oncologic and functional outcomes for clival malignancies:a case series.

Introduction: Clival malignancies pose particular surgical challenges due to complex skull base anatomy and the involvement of vital neurovascular structures. While endoscopic endonasal approached are widely used, the outcomes for clival malignancies remain poorly understood. In this study we assessed the impact of endoscopic and open surgical approaches on PFS, time to initiation of radiotherapy, KPS, and GTR rates for clival malignancies.

Functional Outcomes and Quality of Life in Patients with Sinonasal, Nasopharyngeal, and Anterior Skull Base Tumors.

Purpose Of Review: This article will review functional and QOL outcomes among patients treated predominantly for sinonasal and nasopharyngeal malignancies.

Recent Findings: Treatment advances and interdisciplinary supportive care help to lessen the functional impairments and the reduction in quality of life (QOL) that were once accepted as inevitable tradeoffs for cure. Recent progress in QOL and Patient-Reported Outcome (PRO) instruments for this population will be covered.

Impact of salvage surgery for recurrent sinonasal cancers with skull base and intracranial involvement.

Objective: Patients with recurrent sinonasal cancers (RSNCs) often present with extensive involvement of the skull base and exhibit high rates of subsequent recurrence and death after therapy. The impact of salvage surgery and margin status on progression-free survival (PFS) and overall survival (OS) has yet to be demonstrated. The goal of this study was to determine whether skull base resection with negative margins has an impact on outcomes in the recurrent setting.
