The protective role of postoperative radiation therapy in low and intermediate grade major salivary gland malignancies: A study of the Canadian Head and Neck Collaborative Research Initiative.

BACKGROUND: The objective of this study was to examine the utility of postoperative radiation for low and intermediate grade cancers of the parotid and submandibular glands. METHODS: The authors conducted a retrospective, Canadian-led, international, multi-institutional analysis of a patient cohort with low or intermediate grade salivary gland cancer of the parotid or submandibular gland who were treated from 2010 until 2020 with or without postoperative radiation therapy. A multivariable, marginal Cox proportional hazards regression analysis was performed to quantify the association between locoregional recurrence (LRR) and receipt of postoperative radiation therapy while accounting for patient-level factors and the clustering of patients by institution. RESULTS: In total, 621 patients across 14 tertiary care centers were included in the study; of these, 309 patients (49.8%) received postoperative radiation therapy. Tumor histologies included 182 (29.3%) acinic cell carcinomas, 312 (50.2%) mucoepidermoid carcinomas, and 137 (20.5%) other low or intermediate grade primary salivary gland carcinomas. Kaplan-Meier LRR-free survival at 10 years was 89.0% (95% confidence interval [CI], 84.9%-93.3%). In multivariable Cox regression analysis, postoperative radiation therapy was independently associated with a lower hazard of LRR (adjusted hazard ratio, 0.53; 95% CI, 0.29-0.97). The multivariable model estimated that the marginal probability of LRR within 10 years was 15.4% without radiation and 8.8% with radiation. The number needed to treat was 16 patients (95% CI, 14-18 patients). Radiation therapy had no benefit in patients who had early stage, low-grade salivary gland cancer without evidence of nodal disease and negative margins. CONCLUSIONS: Postoperative radiation therapy may reduce LLR in some low and intermediate grade salivary gland cancers with adverse features, but it had no benefit in patients who had early stage, low-grade salivary gland cancer with negative margins.

Identifying locally actionable strategies to increase participant acceptability and feasibility to participate in Phase I cancer clinical trials.

BACKGROUND: Recruitment of cancer clinical trial (CCT) participants, especially participants representing the diversity of the US population, is necessary to create successful medications and a continual challenge. These challenges are amplified in Phase I cancer trials that focus on evaluating the safety of new treatments and are the gateway to treatment development. In preparation for recruitment to a Phase I recurrent head and neck cancer (HNC) trial, we assessed perceived barriers to participation or referral and suggestions for recruitment among people with HNC and community physicians (oncologist, otolaryngologist or surgeon). METHODS: Between December 2020 and February 2022, we conducted a qualitative needs assessment via semistructured interviews with a race and ethnicity-stratified sample of people with HNC (n = 30: 12 non-Hispanic White, 9 non-Hispanic African American, 8 Hispanic and 1 non-Hispanic Pacific Islander) and community physicians (n = 16) within the University of Florida Health Cancer Center catchment area. Interviews were analyzed using a qualitative content analysis approach to describe perspectives and identify relevant themes. RESULTS: People with HNC reported thematic barriers included: concerns about side effects, safety and efficacy; lack of knowledge and systemic and environmental obstacles. Physicians identified thematic barriers of limited physician knowledge; clinic and physician barriers and structural barriers. People with HNC and physicians recommended themes included: improved patient education, dissemination of trial information and interpersonal communication between community physicians and CCT staff. CONCLUSIONS: The themes identified by people with HNC and community physicians are consistent with research efforts and recommendations on how to increase the participation of people from minoritized populations in CCTs. This community needs assessment provides direction on the selection of strategies to increase CCT participation and referral. PATIENT OR PUBLIC CONTRIBUTION: This study focused on people with HNC and community physicians' lived experience and their interpretations of how they would consider a future Phase I clinical trial. In addition to our qualitative data reflecting community voices, a community member reviewed the draft interview guide before data collection and both people with HNC and physicians aided interpretation of the findings.

The beavertail modified radial forearm free flap: Retrospective review of a versatile technique to increase flap bulk in the head and neck.

OBJECTIVE: Utilization of free tissue transfers in head and neck reconstruction has greatly increased due to their dependability and reliability. Anterolateral thigh (ALT) and rectus abdominus (RA) free flaps may provide too much soft tissue bulk, especially in patients with a large body habitus. A radial forearm free flap (RFFF) may be modified with a "beaver tail" (BT), which provides a flap whose bulk may be tailored to a defect. The purpose of this paper is to describe the technique, how it can be used for a variety of defects and the outcomes of these reconstructions. METHODS: A retrospective review of prospectively collected data was performed at single tertiary care center between 2012 and 2022. BT-RFFF was designed by leaving a fibroadipose tail vascularized to branches of the radial artery or separated from the vascular pedicle and left attached to the proximal portion of the skin paddle. Functional outcomes, tracheostomy dependence, and gastrostomy tube (G-tube) dependence as well as complications were determined. RESULTS: Fifty-eight consecutive patients undergoing BTRFFF were included. Defects reconstructed included: oral tongue and/or floor of mouth 32 (55%), oropharynx 10 (17%), parotid 6 (10%), orbit 6 (10%), lateral temporal bone 3 (5%), and mentum 1 (2%). Indications for BTRFF were: need for bulk when the ALT and RA were too thick (53%) and need for a separate subcutaneous flap for contouring or deep defect lining (47%). Complications directly related to beavertail included a widened forearm scar (100%), wrist contracture (2%) partial flap loss (2%), and flap loss requiring a revision flap (3%). Ninety-three percent of patients with oral/oropharyngeal defects and 12-month follow-up tolerated oral intake without aspiration and 76% were tube-independent. Ninety-three percent were tracheostomy-free at last follow-up. CONCLUSION: The BTRFF is a useful tool for reconstructing complex 3D defects requiring bulk where an ALT or rectus would otherwise provide too much bulk.

Postoperative Radiotherapy for Cutaneous Melanoma in Patients at High Risk of Local-Regional Recurrence after Surgery Alone.

We evaluated outcomes in 131 patients with cutaneous melanoma (median follow-up, 3.6 years) considered at high risk of recurrence after surgery alone treated with surgery and postoperative radiotherapy. Eligible patients had one or more of the following: recurrence after surgery, positive lymph nodes, extracapsular extension, incomplete regional node dissection, microscopically positive margins, gross residual disease, or in-transit metastases. 102 patients received hypofractionated radiotherapy and 29 had conventional fractionation. 10-year outcomes were: in-field local-regional control, 87%; local regional control, 72%; distant metastasis-free survival, 48%; cause-specific survival, 44%; and overall survival, 31%. Three patients experienced acute toxicities while 6 experienced late toxicities.

Woody hardness classification impact on salvage laryngectomy functional outcomes.

PURPOSE: Post-radiation therapy salvage surgeries are challenging for surgeons due to tissue fibrosis. The woody hardness classification is valuable in differentiating the degree of neck stiffness, but its clinical utility has not been evaluated. We applied it to patients undergoing salvage laryngectomy to study the impact of woody hardness on postoperative outcomes. MATERIALS AND METHODS: A retrospective observational study was performed on patients undergoing salvage laryngectomy between 2014 and 2019. Patients were assigned into the A (extremely woody hard), B (moderately woody hard), or C (mildly woody hard) woody hardness class. The primary outcome was pharyngoesophageal stricture development. Secondary outcomes included time to pharyngoesophageal stricture, pharyngocutaneous fistula development, time to pharyngocutaneous fistula, development of post-operative complications, and tracheoesophageal puncture complications. RESULTS: Fifty-one patients were included in the study: Class A 1 patient, Class B 30 patients, and Class C 20 patients. The single Class A patient was grouped with the Class B patients. The development of a pharyngoesophageal stricture shows consistent negative association with woody hardness despite most analyses not reaching statistical significance. These associations are robust to a number of confounding variables in multivariate logistic and time to event analyses. Furthermore, the time to event analysis controlling for squamous cell carcinoma diagnosis led to a statistically significant association between woody hardness (i.e., A/B higher risk) and time to stricture (HR=5, p=0.02). CONCLUSIONS: This study suggests that this classification may be useful in predicting pharyngoesophageal stricture formation in salvage laryngectomy patients and could be used to implement stricture preventive measures.

HPV/p16-positive oropharyngeal cancer treated with transoral robotic surgery: The roles of margins, extra-nodal extension and adjuvant treatment.

PURPOSE: Human papilloma virus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) treatment outcomes are re-defining management. Traditional margins, the role of extranodal extension (ENE) and adjuvant treatment intensity continue to be debated. This study aimed to determine the impact of margins, ENE and adjuvant therapy on survival following transoral robotic surgery (TORS). METHODS: Patients treated with TORS at an academic center were retrospectively identified (2013-2019). Survival outcomes were evaluated using Kaplan-Meier curves. RESULTS: 48 patients were included. 40 (83%) were male. Mean age was 61.2 years. 43 (90%) were stage I. 22 (45.8%) had ENE. 31 (65%) had margins >1 mm. 38 (79%) had indications for radiation therapy; 9 (24%) refused. Chemotherapy was recommended in 36 (75%) patients; 24 (67%) refused. Locoregional control was 98%, metastasis-free survival was 96%, and disease-specific survival was 100% at 5-years. Overall survival was 95%. CONCLUSIONS: Given the high survival rate seen after TORS, it is likely that margins, ENE and adjuvant treatment may not significantly contribute to outcomes.

2b or not 2b? Shoulder function after level 2b neck dissection: A double-blind randomized controlled clinical trial.

BACKGROUND: Selective neck dissection (SND) is a mainstay of head and neck cancer treatment. A common sequela is shoulder syndrome from spinal accessory nerve (SAN) trauma. Extensive dissection in neck levels 2 and 5 leads to SAN dysfunction. However, it is not known whether limited level 2 dissection reduces SAN injury. The purpose of this double-blind randomized controlled trial was to determine whether omitting level 2b dissection would improve shoulder-related quality of life and function. METHODS: Patients with head and neck cancers undergoing surgery were randomized 1:1 to SND without level 2b dissection (group 1) or with it (group 2) on their dominant-hand side. Patients, caregivers, and assessors were blinded. The primary outcome was the change in the Neck Dissection Impairment Index (NDII) score after 6 months. An a priori calculation of the minimally important clinical difference in the NDII score was determined to establish a sample size of 15 patients per group (power = 0.8). Secondary outcomes included shoulder strength and range of motion (ROM) and SAN nerve conduction. The trial was registered at ClinicalTrials.gov (NCT00765791). RESULTS: Forty patients were enrolled, and 30 were included (15 per group). Six months after the surgery, group 2 demonstrated a significant median decrease in the NDII from the baseline (30 points) and in comparison with group 1, whose NDII dropped 17.5 points (P = .02). Shoulder ROM and SAN conduction demonstrated significant declines in group 2 (P ≤ .05). No adverse events occurred. CONCLUSIONS: Level 2b should be omitted in SND when this is oncologically safe and feasible. This allows for an optimal balance between function and cancer cure.

Prophylactic antibiotics in head and neck free flap surgery: A novel protocol put to the test.

OBJECTIVE: Recent evidence supports the use of ampicillin-sulbactam as a favored choice for antibiotic prophylaxis following head and neck free flap reconstructive surgery. However, there is a paucity of evidence guiding the optimal duration of antibiotic prophylaxis. The aim of this study is to compare the infection rates of short courses of ampicillin-sulbactam versus extended courses of various antibiotics in head and neck free flap reconstructive surgery. METHODS: This is a retrospective cohort study conducted from 2012 to 2017 at a tertiary academic center on 266 consecutive patients undergoing head and neck surgery with free flap reconstruction. The primary outcome measure was the rate of any infection within 30 days of surgery. RESULTS: There were 149 patients who received antibiotic prophylaxis for an extended duration of at least seven days. 117 patients received a short course of antibiotics defined as 24 h for non-radiated patients and 72 h for radiated patients. Postoperative infections occurred in 45.9% of patients, of which 92.6% occurred at surgical sites. There was no significant difference in terms of postoperative infection rate between patients receiving an extended duration of antibiotics versus a short duration (p = 0.80). This held true for subgroups of surgical site infections (p = 0.38) and distant infections (p = 0.59 for pneumonia and p = 0.76 for UTI). Risk factors for infections were identified as hypothyroidism (p = 0.047) and clean contaminated wound classification (p = 0.0002). CONCLUSION: Shorter duration of ampicillin-sulbactam prophylaxis in free flap reconstruction of head and neck defects does not negatively affect postoperative infection rates. LEVEL OF EVIDENCE: Level 2b.

Management of cutaneous Merkel cell carcinoma.

PURPOSE: To report the outcomes of patients with previously untreated cutaneous Merkel cell carcinoma (MCC) managed with curative intent. MATERIAL AND METHODS: Between December 1984 and August 2015, 59 patients with previously untreated cutaneous MCC were managed with curative intent with surgery and adjuvant radiotherapy (54 patients) or radiotherapy alone (5 patients) at the University of Florida. Primary sites included head and neck (45 patients), extremities (11 patients) and trunk (3 patients). Adjuvant chemotherapy was employed in 14 patients. Patients were staged according to the AJCC staging system: stage I, 25 patients; stage IIA, 7 patients; and, stage III, 27 patients. No patients had distant metastases. Median follow-up for all patients was 3.2 years (range, 0.3-20.9 years). Median follow-up for survivors was 6.7 years (range, 1.6-20.9 years). RESULTS: The 5-year outcomes were as follows: local control, 91%; regional control, 79%; local-regional control, 77%; disease metastasis-free survival, 60%; cause-specific survival, 53%; and overall survival, 39%. The 5-year outcomes for patients with stage I-IIA versus stage-III disease were the following: local-regional control, 90% versus 57% (p = .0115); distant metastasis-free survival, 78% versus 36% (p = .0002); cause-specific survival, 68% versus 35% (p = .0050); and overall survival, 48% versus 27% (p = .0377). Local-regional recurrences occurred in 12 patients; no patients were successfully salvaged. Severe late complications were observed in four patients. CONCLUSIONS: Although radiotherapy alone or combined with surgery results in a relatively high likelihood of local-regional control, the majority of recurrences are distant and approximately half of patients are cured. Patients with regional disease at diagnosis have significantly worse outcomes.

Follicular thyroid carcinoma metastasis to the facial skeleton: a systematic review.

BACKGROUND: Follicular thyroid carcinoma (FTC) metastasis to the facial skeleton is exceedingly rare. A case of FTC metastasizing to the mandible is presented and a systematic review of the literature describing thyroid metastasis to the facial skeleton is performed. CASE PRESENTATION: A 73-year-old female presented with metastatic FTC to the mandible and underwent total thyroidectomy, segmental mandibulectomy, bone impacted fibular free flap reconstruction, and adjuvant radioactive iodine treatment. The PubMed database was searched for literature describing thyroid cancer with facial skeleton metastasis using the key words "thyroid," "cancer," "carcinoma," "metastasis," and "malignancy" with "oral cavity," "maxilla," "mandible," "sinus," "paranasal," and "orbit." Reports that only involved the soft tissues were excluded. Systematic review revealed 59 cases of well-differentiated thyroid cancer with facial skeleton metastasis: 35 mandibular metastases (21 = FTC), 6 maxilla metastases (2 = FTC), 9 orbital metastases (4 = FTC), and 11 paranasal sinus metastases (7 = FTC). Treatment included surgery, RAI, external beam radiotherapy (XRT), or a combination of these modalities. The one, two, and five-year survival rates were 100%, 79%, and 16%, respectively. CONCLUSION: Facial skeleton metastasis of FTC is a rare clinical challenge. Optimal treatment appears to include total thyroidectomy and resection of involved structures with or without adjuvant treatment.

Outcomes after primary or adjuvant radiotherapy for salivary gland carcinoma.

BACKGROUND: We report long-term outcomes of patients treated with primary radiotherapy (RT) or surgery and adjuvant RT for salivary gland malignancies. MATERIALS AND METHODS: From 1964 to 2012, 291 patients received primary RT (n = 67) or RT combined with surgery (n = 224). RESULTS: The 5-, 10-, and 15-year local control, local-regional control, distant metastasis-free survival, cause-specific survival and overall survival rates were 82%, 77% and 73%; 77%, 72% and 67%; 74%, 70% and 70%; 70%, 59% and 54%; and 63%, 47% and 38%, respectively. Per multivariate analysis, combined surgery and RT and T stage impacted local control; overall stage and combined surgery and RT impacted local-regional control; overall stage impacted distant metastasis-free survival; and overall stage, node positivity, clinical nerve invasion, and surgery and RT impacted cause-specific and overall survival. Five percent of patients experienced grade 3 or worse toxicity. CONCLUSION: Combined surgery and RT improves local control, local-regional control, and cause-specific survival compared with primary RT for salivary tumors.

Primary radiotherapy for squamous cell carcinoma of the pyriform sinus.

The objective of this study is to report the long-term outcomes of primary radiotherapy (RT) for patients with T1-T2 squamous cell carcinomas (SCC) of the pyriform sinus. Between November 1964 and March 2008, 135 patients with T1-T2 pyriform sinus SCC were treated with primary RT at the University of Florida. Adjuvant chemotherapy was employed in 21 patients (16 %) and 62 patients (46 %) underwent a planned neck dissection. Median follow-up was 3.5 years (range 0.2-24.7 years); median follow-up on living patients was 8.3 years (range 3.8-24.0 years). The 5-year outcomes were as follows: local control, 85 %; regional control, 81 %; local-regional control, 71 %; distant metastasis-free survival, 76 %; cause-specific survival, 62 %; and overall survival, 38 %. The 5-year local control rate was 88 % for T1 cancers and 84 % for those with T2 SCCs (p = 0.5429). Sixteen patients (12 %) experienced severe late complications. Primary RT results in a high probability of cure with a relatively modest risk of severe late complications for patients with T1-T2 SCCs of the pyriform sinus.

Radiation therapy for nasal vestibule squamous cell carcinoma: a 40-year experience.

We evaluated the treatment of squamous cell carcinoma (SCC) of the nasal vestibule. Eighty-six patients were treated with radiotherapy (RT) and 13 patients received surgery and RT. The mean follow-up was: 9.7 years (range 4 months-35.9 years). The 5- and 10-year outcomes were: local control (LC), 88 and 82 %; local-regional control (LRC), 78 and 73 %; freedom from distant metastases (FFDM), 96 and 96 %; cause-specific survival (CSS), 91 and 86 %; and overall survival, 75 and 51 %. The 5- and 10-year LC rates for patients treated with RT were 94 and 89 % overall. A multivariate analysis was performed. Tumor size predicted LC, LRC, OS, and CSS. Overall stage predicted LRC. RT cures most patients with T1-T2 and favorable T4 SCCs with acceptable toxicity. RT and surgery result in improved likelihood of cure for patients with advanced T4 lesions.

Ipsilateral radiotherapy for squamous cell carcinoma of the tonsil.

The purpose of this study is to update our institution's experience with ipsilateral radiation therapy (RT) for squamous cell carcinoma of the tonsillar area. Outcome study of 76 patients treated between 1984 and 2012 with ipsilateral RT for squamous cell carcinoma of the tonsil. Patients had either cT1 (n = 41, 54 %) or cT2 (n = 35, 46 %) primaries and cN0 (n = 27, 36 %), cN1 (n = 15, 20 %), cN2a (n = 8, 11 %), or cN2b (n = 26, 34 %) nodal disease. Of these, 32 (42 %) patients underwent a planned neck dissection and 21 (28 %) patients received concomitant chemotherapy. Median follow-up for all patients was 7.1 years (range 0.1-27.2) and 7.8 years (range 2.1-27.2 years) for living patients. The 2- and 5-year control and survival rates were as follows: local control, 98.6 and 96.9 %; local-regional control 95.8 and 92.6 %; cause-specific survival 95.9 and 93.1 %; and overall survival, 92.1 and 83.8 %. One patient failed in the contralateral, non-radiated neck 3 years after primary treatment. Univariate analysis revealed that overall survival was significantly influenced by whether the patient had a primary tumor in the anterior tonsillar pillar versus the tonsillar fossa with the latter performing better. The incidence of severe late complications was 16 %. Ipsilateral RT for patients with squamous cell carcinoma of the anterior tonsillar pillar or tonsillar fossa with no base of tongue or soft palate extension is an efficacious treatment that provides excellent control rates with a relatively low incidence of late complications.

Transoral robotic surgery (TORS) for laryngeal and hypopharyngeal cancers.

Transoral robotic surgery (TORS) is increasingly used in laryngeal/hypopharyngeal cancer surgery. Ablative procedures described in these anatomical sites include: (i) supraglottic laryngectomy, (ii) total laryngectomy, (iii) glottic cordectomy, and (iv) partial pharyngectomy. TORS supraglottic laryngectomy remains the most commonly performed of these procedures. Initial oncologic and functional outcomes with these procedures are promising and comparable to other treatment options. As robotic instrumentation technology advances a rise in TORS laryngeal/hypopharyngeal surgery is anticipated.

Transoral robotic surgery for carcinoma of unknown primary in the head and neck.

Multiple diagnostic and treatment paradigms exist for the management of carcinoma of unknown primary (CUP) metastatic to cervical lymph nodes. Transoral robotic surgery (TORS) has emerged as a modality for diagnosis and treatment of CUP, optimizing identification and resection of the primary tumor, although also preventing chemotherapy in a subset of patients. This article presents the authors' treatment paradigm and reviews the literature supporting the use of TORS in the management of CUP.

Retromolar trigone squamous cell carcinoma treated with radiotherapy alone or combined with surgery: a 10-year update.

PURPOSE/OBJECTIVES: Treatment outcomes were analyzed for patients who received radiotherapy for squamous cell carcinoma of the retromolar trigone at a single institution. MATERIALS/METHODS: We reviewed the medical records of 110 patients treated with radiotherapy alone (n=36) or radiotherapy combined with surgical resection of the primary tumor (n=74) between June 1966 and October 2013. The median follow-up was 4.5years for all patients and 11.8years for living patients (range, 1.3-23.5years). RESULTS: The 5-year local-regional control rates after definitive radiotherapy versus surgery and radiotherapy for stages I-III were 52% and 89% and for stage IV they were 46% and 58%, respectively. The 5-year cause-specific survival rates after definitive radiotherapy compared with surgery and radiotherapy for stages I-III were 57% and 82% and for stage IV they were 45% and 43%, respectively. Multivariate analyses revealed that the likelihood of cure was better with surgery and radiotherapy compared with radiotherapy alone (p=0.041). CONCLUSION: Patients treated with surgery and radiotherapy had a better chance of cure than those treated with radiotherapy alone. Complications of treatment were common in both groups but more common in patients who underwent surgery.

Feasibility and clinical outcomes of transoral robotic surgery and transoral robot-assisted carbon dioxide laser for hypopharyngeal carcinoma.

Transoral robotic surgery (TORS) has been used as a novel procedure for squamous cell carcinoma of the laryngopharyngeal cancers with encouraging outcomes. The safety, feasibility, and efficacy regarding this approach have previously been demonstrated. There are several studies proposing the benefit of combining TORS with carbon dioxide (CO2) laser in resecting upper aerodigestive tract tumors. We report a series of patients with hypopharyngeal carcinoma treated with primary TORS with or without the flexible carbon dioxide (CO2) laser. All TORS resections were completed without any intraoperative complication. None required conversion to an open procedure. Clinical outcomes in this preliminary analysis indicate that magnified view, 3D visualization with the wristed instruments and tremor reduction technology of robotic experience, allow en bloc resection of early stage hypopharyngeal cancers. TORS with CO2 laser is a promising, minimally invasive surgical alternative for the treatment of hypopharyngeal tumors with comparable oncologic outcomes.

Radiotherapy for benign head and neck paragangliomas: a 45-year experience.

BACKGROUND: Paragangliomas of the head and neck are rare, slow-growing, generally benign tumors of neuroendocrine cells associated with the peripheral nervous system that commonly involve the carotid body, jugular bulb, vagal ganglia, and temporal bone. Treatment options include surgery, radiotherapy (RT), stereotactic radiosurgery (SRS), and observation. This article briefly reviews our 45-year institutional experience treating this neoplasm with RT. METHODS: From January 1968 through March 2011, 131 patients with 156 benign paragangliomas of the temporal bone, carotid body, jugular bulb, or glomus vagale were treated with RT at a median dose of 45 Gy in 25 fractions. The mean and median follow-up times were 11.5 years and 8.7 years, respectively. RESULTS: Five tumors (3.2%) recurred locally after RT, all within 10 years of treatment. The overall local control rates at 5 and 10 years were 99% and 96%, respectively. The cause-specific survival rates at 5 and 10 years were 98% and 97%, respectively. The distant-metastasis free survival rates at 5 and 10 years were 99% and 99%, respectively. The overall survival rates at 5 and 10 years were 91% and 72%, respectively. There were no severe complications. CONCLUSION: RT for benign head and neck paragangliomas is a safe and efficacious treatment associated with minimal morbidity. Surgery is reserved for patients in good health whose risk of associated morbidity is low. SRS may be suitable for patients with skull base tumors <3 cm where RT is logistically unsuitable. Observation is a reasonable option for asymptomatic patients with a limited life expectancy.
