RESUMO
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. We reviewed medical records for all patients surgically treated for an ITF malignancy between January 1, 1999, and December 31, 2017, at our institution. We collected patient demographics, preoperative performance, tumor stage, tumor characteristics, treatment modalities, pathological data, and postoperative performance data. The 5-year survival rate was 62.2%. Higher preoperative Karnofsky Performance Status (KPS) score (n = 64; p < 0.001), short length of stay (p = 0.002), prior surgery at site (n = 61; p = 0.0164), and diagnosis of sarcoma (n = 62; p = 0.0398) were predictors of higher postoperative KPS scores. Percutaneous endoscopic gastrostomy (PEG) (n = 9; p = 0.0327), and tracheostomy tube placement (n = 20; p = 0.0436) were predictors of lower postoperative KPS scores, whereas age at presentation (p = 0.72), intracranial tumor spread (p = 0.8197), and perineural invasion (n = 40; p = 0.2195) were not. Male patients and patients with carcinomas showed the greatest decreases in KPS scores between pretreatment and posttreatment. Higher preoperative KPS score and short length of stay were the best predictors of higher postoperative KPS scores. This work provides treatment teams and patients with better information on outcomes for shared decision-making.

BACKGROUND: A radical parotidectomy with facial nerve sacrifice results in facial nerve paralysis as well as a volume and often cutaneous defect. Prior experience with nerve grafting and static suspension has yielded suboptimal results. The present report aims to examine the feasibility and outcomes of a combined free gracilis and profunda artery perforator (PAP) flap from a single donor site can reconstruct these extensive defects and potentially restore dynamic facial reanimation even in the setting of adjuvant radiation. PATIENTS AND METHODS: A retrospective review of 10 patients (6 males and 4 females) was performed from 2016 to 2020 that underwent a combined PAP-gracilis reconstruction of a radical parotidectomy defect. All patients (mean age: 71.3 years; range: 52-83 years) received adjuvant radiation. A chimeric PAP-gracilis flap requiring a single microvascular anastomosis was performed in three patients while the remaining patients underwent a double free flap reconstruction. RESULTS: The gracilis flap was innervated using the facial nerve stump, spinal accessory and massecteric nerve in three patients each. One patient's gracilis was innervated using the hypoglossal nerve. Three patients also underwent nerve grafting of the facial nerve. One patient was taken back to the operating room for a hematoma in the recipient site and there were not flap losses of either the PAP or gracilis flap. Two patients had delayed wound healing of the donor site that healed with conservative management. Average follow-up was 11.1 months (range: 8.1-19.5 months). Six patients were able to achieve dynamic animation while the others obtained a static reconstruction and did not have issues with drooling, eating, or speaking. CONCLUSIONS: Immediate functional muscle transfer can potentially restore dynamic facial reanimation even following radiation. Combining reconstruction using a PAP-gracilis flap addresses the soft tissue deficit and facial paralysis using a single donor site in a single operation.

Emerging immunotherapeutic agents, including immune checkpoint inhibitors targeting cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein 1 (PD-1), and programmed cell death protein ligand 1 (PD-L1), have revolutionized cancer treatment. The first immune checkpoint inhibitor (ICI) ipilimumab, an anti-CTLA-4, was approved in 2011. Since then, the US Food and Drug Administration (FDA) has approved more than half a dozen immune checkpoint inhibitors to treat various malignancies. These agents are part of a broader class of chemotherapy agents termed immunotherapy, which selectively target different steps in the immune response cascade to upregulate the body's normal response to cancer. While the effects of traditional chemotherapy are well known, the toxicity profile of emerging immune therapies is not fully elucidated. They have been associated with atypical side effects labeled collectively as immune-related adverse events (irAEs).

INTRODUCTION: Malignancies involving the temporal bone are increasingly common and require specialized multi-disciplinary care. Given this complex location, involvement of the lateral skull base and local neurovascular structures is common. In this review we discuss general principles for temporal bone resection, as well as alternative and complementary surgical approaches that should be considered in the management of patients with temporal bone cancer. METHODS: A comprehensive review on literature pertaining to temporal bone resection was performed. RESULTS: The primary surgical strategy for malignancies of the temporal bone is temporal bone resection. This may be limited to the ear canal and tympanic membrane (lateral temporal bone resection) or may include the otic capsule and its contents (subtotal temporal bone resection), and/or the petrous apex (total temporal bone resection). Management of adjacent neurovascular structures including the facial nerve, the carotid artery, and the jugular bulb/sigmoid sinus should be considered during surgical planning. Finally, adjunctive procedures such as parotidectomy and neck dissection may be required based on tumor stage. CONCLUSIONS: Temporal bone resection is an important technique in the treatment of lateral skull-base malignancies. This strategy should be incorporated into a multi-disciplinary approach to cancer.

Emerging immunotherapy agents, such as immune checkpoint inhibitors, have shown remarkable promise in the treatment of various malignancies. These drugs selectively target different steps in the immune response cascade to upregulate the body's normal response to cancer. Due to the novelty of these therapeutic agents, their toxicity profile is less well understood.Meta-analysis results reveal that the overall prevalence of oral mucositis, stomatitis, and xerostomia is lower with checkpoint inhibitors compared to conventional chemotherapy, and head and neck radiation therapy. However, the widespread use of immunotherapy reveals new oral mucosal barrier adverse events, including bullous pemphigoid, mucous membrane pemphigoid, and lichenoid mucositis. Audiovestibular dysfunction can occur from autoimmune-mediated pathways of immunotherapy (adoptive cell) with limited treatment options. Such auditory complications can lead to speech recognition deficits and sensorineural hearing loss. Ocular toxicities are among the most common adverse events resulting from the use of these agents. The majority of ocular immune-related adverse events (irAEs) are mild, low-grade, non-sight threatening, such as blurred vision, conjunctivitis, and ocular surface disease. Serious and sight-threatening events, including corneal perforation, optic neuropathy, and retinal vascular occlusion, can occur but are infrequent. In this chapter, we review the current evidence on the clinical manifestations of oral, audiovestibular, and ocular immune-related adverse events (i.e., irAEs).

OBJECTIVE: To review efficiency metrics and patient safety data before and after implementation of a structured review process for surgical innovations. SUMMARY BACKGROUND DATA: Surgical innovation ranges from minor incremental improvement to radical experimentation. Although innovation paradigms have been described, these are not widely adopted or enforced in the surgical community. METHODS: A Continuous Quality Improvement Team (CQIT) of surgical quality officers and perioperative nurses was organized to perform structured reviews of proposed new surgical devices and procedures at a large quaternary cancer care center. The CQIT process was placed to precede an established Value Analysis Team business evaluation. Pre- and post-CQIT implementation metrics of approval process efficiency and patient safety data were compared. Seven novel procedures were also vetted by the CQIT. RESULTS: Forty-six product requests were evaluated after CQIT implementation. Compared with 34 products evaluated prior to CQIT establishment, the total mean evaluation time decreased from 124 to 51 days (P= 0.007). For new devices requiring intraoperative trial, the time between product proposal and trial decreased from a mean of 260 to 99 days (P= 0.014). The rate of device-related complications in the pre-CQIT group was 10% compared with 0% post-CQIT. Two devices, which administratively bypassed CQIT review, had both minor and major complications, including a mortality. Five novel procedures approved by CQIT with simulation were performed without complications. CONCLUSIONS: Using novel algorithms, the addition of a dedicated team of surgical quality officers to the surgical innovation evaluation process improved both the efficiency and the safety associated with introducing new devices and procedures into practice.

BACKGROUND: No guidelines exist regarding physicians' duty to inform former patients about novel genetic tests that may be medically beneficial. Research on the feasibility and efficacy of disseminating information and patient opinions on this topic is limited. METHODS: Adult patients treated at our institution from 1950 to 2010 for medullary thyroid cancer, pheochromocytoma, or paraganglioma were included if their history suggested being at-risk for a hereditary syndrome but genetic risk assessment would be incomplete by current standards. A questionnaire assessing behaviors and attitudes was mailed 6 weeks after an information letter describing new genetic tests, benefits, and risks was mailed. RESULTS: Ninety-seven of 312 (31.1%) eligible patients with an identified mailing address returned the questionnaire. After receiving the letter, 29.2% patients discussed genetic testing with their doctor, 39.3% considered pursuing genetic testing, and 8.5% underwent testing. Nearly all respondents (97%) indicated that physicians should inform patients about new developments that may improve their or their family's health, and 71% thought patients shared this responsibility. Most patients understood the letter (84%) and were pleased it was sent (84%), although 11% found it upsetting. CONCLUSIONS: Patients believe it is important for physicians to inform them of potentially beneficial developments in genetic testing. However, physician-initiated letters to introduce new information appear inadequate alone in motivating patients to seek additional genetic counseling and testing. Further research is needed regarding optimal methods to notify former patients about new genetic tests and corresponding clinical and ethical implications.

OBJECTIVE: To determine if early access to multidisciplinary surgical care affects outcomes in patients with skull base chordoma. METHOD: A retrospective chart review of prospectively collected data was performed on 51 patients treated from 1993 to 2014. The cohort was divided into those presenting (1) for initial management (ID, n = 21) or (2) with persistent/progressive disease after prior biopsy/surgery (PD, n = 30) outside of a multidisciplinary setting. The impact of initial surgical management in a multidisciplinary center on progression-free survival (PFS) was assessed with Kaplan-Meier and log-rank analyses. RESULTS: Mean follow-up, median PFS, median overall survival (OS), and 10-year OS for the entire cohort was 70 months, 47 months, 159 months, and 19%, respectively. Initial management in a multidisciplinary center resulted in a significant improvement in PFS versus initial surgery with or without radiotherapy (XRT) outside of this setting (64 vs 25 months, p = 0.035). Initial surgical resection outside of a multidisciplinary setting increased the risk of recurrence/progression on univariate (HR, 2.276; p = 0.022) and multivariate analysis (HR, 2.831; p = 0.006), respectively. CONCLUSIONS: The results from this study emphasize the impact that coordinated multidisciplinary surgical care has on patient outcomes for chordomas of the clivus. Biopsy followed by attempted radical resection at a dedicated center does not affect PFS and, therefore, represents a reasonable first step in management for patients presenting outside of multidisciplinary setting.

PURPOSE: To assess myringotomy plus tympanostomy tube (MTT) complication rates in head and neck cancer (HNC) patients with otitis media (OM). MATERIALS AND METHODS: We performed a retrospective review of 182 HNC patients with OM treated between January 2000 and October 2007 for demographic data and data about MTT-related complications, tumor type and outcomes following MTT. RESULTS: We identified OM in 35 nasopharyngeal (NP), 34 paranasal sinus (PNS), and 24 larynx cancer patient ears; of these, 29 (83%), 31 (91%), and 22 (92%), respectively, were treated with MTT. Of the 29 NP cancer patient ears treated with MTT, 13 (45%) received MTT before radiotherapy; complications included otorrhea in 11 ears (38%), otorrhea with perforation in 3 ears (10%), and cholesteatoma in 1 ear (3%). Of the 31 PNS cancer patient ears treated with MTT, 17 (55%) received MTT before radiotherapy; complications included otorrhea in 10 ears (32%) and otorrhea with perforation in 3 ears (10%). All 22 laryngeal cancer patient ears were treated with MTT before radiotherapy; 5 ears (23%) developed chronic otorrhea. Patients with pre-existing eustachian tube dysfunction had significantly higher rates of tympanostomy tube otorrhea (p=.009). CONCLUSIONS: The complication rates of OM in the setting of NP or PNS cancer were not significantly different regardless of intervention timing in relation to radiotherapy. Laryngectomy patients had a high rate of tympanostomy sequelae after radiotherapy. MTT for OM has high complication rates in HNC patients.

OBJECTIVES: Ototoxic hearing loss associated with intravenous or intra-arterial administration of cisplatin is well documented. However, there is limited data regarding the ototoxic effect of cisplatin when perfused into the abdominal cavity using hyperthermic intraperitoneal chemotherapy (HIPEC). The purpose of this study is to assess and describe ototoxicity in patients treated with HIPEC with cisplatin and sodium thiosulfate for peritoneal surface malignancies. DESIGN: We performed a retrospective chart review (2007-2012) of patients treated for advanced peritoneal malignancies at a tertiary care center using HIPEC with cisplatin and sodium thiosulfate infusion. Thirteen patients (12 males, 1 female) met study criteria. Audiometric thresholds were compared before and after treatment. A 20 dB loss at any single frequency, 10 dB decrease at any two adjacent frequencies, or loss of response at three consecutive test frequencies defined a significant ototoxic change (). RESULTS: Despite minimal hearing change in six patients, none of the 13 patients in our study exhibited a significant ototoxic change in hearing sensitivity post HIPEC with cisplatin at any test interval in any test frequency. CONCLUSIONS: Our findings represent the first objective assessment of ototoxic effect after HIPEC with cisplatin and sodium thiosulfate infusion. Our results suggest that peritoneal perfusion of cisplatin with intravenous perfusion of sodium thiosulfate is not associated with ototoxic changes in hearing sensitivity. Further investigation of the administration and systemic mechanism of absorption of sodium thiosulfate as a potential protection against cisplatin ototoxicity is needed to confirm these findings.

PURPOSE: The goal of this study was to describe computed tomographic findings in patients with clinically proven temporal bone (TB) osteoradionecrosis (ORN) (TB-ORN). MATERIALS AND METHODS: Computed tomographic scans of 20 patients were retrospectively evaluated for bony and soft tissue abnormalities. Clinical severity was graded based on level of therapy administered: mild (observation), moderate (antibiotics/hyperbaric oxygen), or severe (surgery). RESULTS: Radiation dose to the primary tumor ranged from 30 to 75.6 Gy. Time to onset of ORN from completion of radiation therapy was 2 to 22 years (median, 7 years). CLINICAL FINDINGS: exposed bone, 20 of the 20 patients; otorrhea, 17 of the 20 patients; hearing loss, 11 of the 20 patients; otalgia, 10 of the 20 patients; facial nerve paralysis, 2 of the 20 patients; gait imbalance, 2 of the 20 patients. Computed tomographic findings: external auditory canal erosions, 18 of the 20 patients; mastoid effusion, 18 of the 20 patients; mastoid bony coalescence, 5 of the 20 patients; enhancing soft tissue, 6 of the 20 patients; soft tissue gas, 6 of the 20 patients; temporomandibular joint/condylar erosion, 3 of the 20 patients.Three patients developed an abscess. CONCLUSION: Mastoid effusion and external auditory canal erosions are commonly seen with TB-ORN. Clinically moderate or severe cases of TB-ORN are more likely to demonstrate enhancing soft tissue (P = 0.002), soft tissue gas (P = 0.002), and temporomandibular joint involvement (P = 0.07).

OBJECTIVE: To determine if cochlear implant (CI) is safe and effective in patients with radiation therapy (XRT)-induced sensorineural hearing loss and to discuss considerations in this population through a retrospective cohort review, systematic review, and meta-analysis. DATABASES REVIEWED: PubMed, Cochrane Library, and Embase. METHODS: We retrospectively reviewed all CI cases after head and neck (HN) XRT at our institution, noting intraoperative findings, postoperative complications, and hearing outcomes. Change in speech discrimination scores (SDSs) was the primary outcome measure. Systematic review was performed to identify all cases of CI after HNXRT. A meta-analysis was performed to assess SDS change. RESULTS: The retrospective cohort review identified 12 patients who underwent CI after HNXRT. One patient with HN cancer (HNC) and one with central nervous system pathology (CNSP) received bilateral implants. Six had HNC, three had CNSP, and one had Langerhans cell histiocytosis. Eleven had abnormal findings during CI. There were no postoperative complications. Twenty articles with an additional 97 patients were suitable for systematic review inclusion. Of the 109 patients, 67 (61.5%) had HNC and 18 (16.5%) had CNSP. Abnormal intraoperative findings were common (30.3%), most frequently in the mastoid (66.7%). Postoperative complications, including wound dehiscence and infection with some requiring explantation, occurred in 10.1% of patients. Sixty-six patients were included in the meta-analysis. All demonstrated SDS improvement (mean increase, 56.2%). CONCLUSION: Patients with prior HNXRT benefit from CI. Paying careful attention to surgical planning and technique, postoperative care, and patient expectations is imperative, as complications are not uncommon.

OBJECTIVE: To evaluate the impact of losartan on vestibular schwannoma (VS) growth and related hearing loss during observation. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary referral center. PATIENTS: Sporadic VS patients undergoing initial observation with at least two magnetic resonance imaging and audiologic examinations. INTERVENTION: Losartan. MAIN OUTCOME MEASURES: Endpoints included VS growth, quantitative audiologic changes, survival free of tumor growth, and survival free of nonserviceable hearing. Patient characteristics and endpoints were compared by losartan use. RESULTS: Seventy-nine patients were included, of which 33% were taking losartan. Tumor growth was observed in 50% of patients in the losartan group and 36% in the non-losartan group (p = 0.329). Survival analysis failed to show a significant difference in the hazard rate of VS growth between groups (hazard ratio, 1.38; 95% confidence interval, 0.70-2.70; p = 0.346). Throughout observation, mean decreases in normalized pure-tone average were 5.5 and 9.3 dB in the losartan and non-losartan groups, respectively (p = 0.908). Mean decreases in normalized word recognition score were 11.0 and 16.6% in the losartan and non-losartan groups, respectively (p = 0.757). Nonserviceable hearing developed in 19% of patients in the losartan group and 28% in the non-losartan group (p = 0.734). Survival analysis did not demonstrate a significant difference in the hazard rate of developing nonserviceable hearing between groups (hazard ratio, 1.71; 95% confidence interval, 0.56-5.21; p = 0.337). CONCLUSIONS: Losartan use may not reduce the risk of VS growth or hearing loss during observation. A randomized trial would be ideal to further identify the true effect on growth and hearing.

OBJECTIVE: Temporal bone squamous cell carcinoma (TBSCC) is a rare malignancy with poor prognosis, and optimal treatment for advanced cases is uncertain. Our systematic literature review aimed to assess 5-year survival outcomes for advanced TBSCC across different treatment modalities. DATA SOURCES: EMBASE, Medline, PubMed, and Web of Science. REVIEW METHODS: A systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for articles published between January 1989 and June 2023. RESULTS: The review yielded 1229 citations of which 31 provided 5-year survival data for TBSCC. The final analysis included 1289 patients. T classification data was available for 1269 patients and overall stage for 1033 patients. Data for 5-year overall survival (OS) was 59.6%. Five-year OS was 81.9% for T1/2 and 47.5% for T3/4 (P < .0001). OS for T1/T2 cancers did not significantly differ between surgery and radiation (100% vs 81.3%, P = .103). For advanced-stage disease (T3/T4), there was no statistical difference in OS when comparing surgery with postoperative chemoradiotherapy (CRT) (OS 50.0%) versus surgery with postoperative radiotherapy (XRT) (OS 53.3%) versus definitive CRT (OS 58.1%, P = .767-1.000). There was not enough data to assess the role of neoadjuvant CRT. CONCLUSION: Most patients will present with advanced-stage disease, and nodal metastasis is seen in nearly 22% of patients. This study confirms the prognostic correlation of the current T classification system. Our results suggest that OS did not differ significantly between surgery and XRT for early stage disease, and combined treatment modalities yield similar 5-year OS for advanced cancers.

SBO is a life-threatening disease that requires a high index of suspicion based on these patients complex underlying medical co-morbidities and clinician's acumen. Once a diagnosis is made, is it critical to communicate and work closely with other multidisciplinary teams (neuroradiology for appropriate choice of imaging study and interpretation; infectious disease for appropriate medical treatment and duration; internist to properly manage their underlying medical co-morbidities). Despite advances in imaging, the diagnosis is first made based on clinical judgment, appropriate culture, and tissue biopsy.

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. Kaplan-Meier survival analyses for PFS and DSS were completed. Univariable and multivariable Cox proportional hazards regression models were used to identify patient-related, treatment-related, and disease-related factors that predicted PFS and DSS. RESULTS: A total of 28 patients and 84 episodes of recurrence were included. One-year PFS was 70.6%, 5-year PFS was 28.9%, and 10-year DSS was 78.5%. The median time to first progression was 23.9 months (range, 2.8-282 months). In univariable Cox proportional hazards regression, male sex, higher grade histology, fourth or greater progression episode status, distal pattern of recurrence, and treatment of recurrence without surgery or with chemotherapy alone predicted worse PFS. Multivariable regression predicted shortened DSS in male patients (hazard ratio [HR] 0.16; P = .021) and higher-grade tumors (HR 0.22; P = .039). Treatment of recurrence with surgery was associated with, but did not significantly predict, improved DSS (HR 1.78; P = .11). CONCLUSION: Several patient and disease-specific factors were associated with shorter PFS and DSS in recurrent skull base chondrosarcoma. For recurrences amenable to resection, surgery is recommended for treatment of recurrent CSA. Local recurrence management without surgery results in shorter PFS and DSS.

OBJECTIVES/HYPOTHESIS: Mycosis Fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma. Disease involvement of specific locations may be more significant than simply the symptoms associated with that site; it is possible that involvement of certain sites could be associated with poor prognosis. We aimed to evaluate the outcomes of patients with MF with documented involvement of the EAC and external ear. STUDY DESIGN: Retrospective analysis. METHODS: We retrospectively reviewed 40 patients with MF that were treated by otologists between 2012 and 2021. RESULTS: We report the largest series of patients with MF involving the external ear and EAC. Of the 40 patients included in this study, 17 presented with Mycosis Fungoides in the otologic region (MFO). Of these 17 MFO patients, 2/17 had involvement of the external ear only, 3/17 of the EAC only, 11/17 of both the external ear and EAC, and 1/17 of the periauricular skin. Of note, 11/14 (79%) patients presenting with EAC disease died compared to11/26 (42%) of patients without involvement. In addition, eight of the 13 (62%) patients with external ear involvement died compared to 14/27 (52%) of patients without involvement. Ear canal involvement was associated with a statistically significant shorter overall survival duration in patients with MF (p = 0.03). Furthermore, disease in the EAC was found to have a hazard ratio value of 2.565 (CI 1.102-5.970). CONCLUSIONS: Involvement of the EAC by MF portends a poor prognosis. This finding highlights the need for a more in-depth otologic evaluation of patients with MF. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:1486-1491, 2023.

OBJECTIVE: Temporal bone squamous cell carcinoma (TBSCC) is rare and often confers a poor prognosis. The aim of this study was to synthesize survival and recurrence outcomes data reported in the literature for patients who underwent temporal bone resection (TBR) for curative management of TBSCC. We considered TBSCC listed as originating from multiple subsites, including the external ear, parotid, and external auditory canal (EAC), or nonspecifically from the temporal bone. DATA SOURCES: PubMed, Cochrane Library, Embase, and manual search of bibliographies. REVIEW METHOD: A systematic literature review conducted in December 2020 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Survival data were collected from 51 retrospective studies, resulting in a pooled cohort of 501 patients with TBSCC. Compared to patients undergoing lateral TBR (LTBR), patients undergoing subtotal (SBTR) or total (TTBR) TBR exhibited significantly higher rates of stage IV disease (P < .001), positive surgical margins (P < .001), facial nerve involvement (P < .001), and recurrent disease (P < .001). A meta-analysis of 15 studies revealed a statistically significant 97% increase in mortality in patients who underwent STBR or TTBR. On multivariate analysis, recurrent disease was independently associated with worse overall survival (P < .001). On univariate analysis, facial nerve involvement was also associated with decreased overall survival (P < .001). CONCLUSION: Recurrent disease was associated with risk of death in patients undergoing TBR. Larger prospective multi-institutional studies are needed to ascertain prognostic factors for a wider array of postoperative outcomes, including histology-specific survival and recurrence outcomes.

OBJECTIVES: To systematically review and evaluate metformin's potential impact on vestibular schwannoma (VS) growth. DATA SOURCES: PubMed, Cochrane Library, and Embase. REVIEW METHODS: A retrospective cohort study was performed on sporadic VS patients undergoing initial observation who had at least two magnetic resonance imaging studies. Patients were stratified by metformin use during the observation period. Primary endpoint was VS growth, defined as at least a 2 mm increase in diameter. Survival free of tumor growth was evaluated between groups. Systematic review and meta-analysis were performed to produce a pooled odds ratio [OR]. Study heterogeneity was assessed and post-hoc power analysis was performed. RESULTS: A total of 123 patients were included, of which 17% were taking metformin. Median patient age was 56.6 years (range, 25.1-84.5). There were no statistically significant differences between the groups. Survival analysis did not demonstrate a statistically significant difference in time to VS growth between groups (hazard ratio = 0.61, 95% confidence interval [CI] = 0.29-1.29). Furthermore, logistic regression analysis did not demonstrate a statistically significant difference between groups in the odds of VS growth (OR = 0.46, 95% CI = 0.17-1.27). Systematic review identified 3 studies. Meta-analysis suggested that metformin reduces the odds of developing VS growth (pooled OR = 0.45, 95% CI = 0.29-0.71). Studies demonstrated low between-study heterogeneity. Power analysis demonstrated a sample size of 220 patients with equal randomization would be required to prospectively identify a true difference with 80% power. CONCLUSIONS: Metformin use may reduce the odds of VS growth. A randomized trial would be ideal to identify an unbiased estimate of metformin's effect on VS growth. Laryngoscope, 133:2066-2072, 2023.
