RESUMO
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. Univariate regression estimated the rate of increase in new patient appointments. Geospatial analysis evaluated patient origin and distribution. RESULTS: The mean new patients per year in 2006-2011 versus 2012-2017 was 2735 ± 156 patients versus 3155 ± 207 patients, including 464 ± 78 patients at HNRCCs, reflecting a 38.4 % increase in overall patient volumes. The rate of increase in new patient appointments did not differ significantly before and after HNRCCs (121.9 vs 95.8 patients/year; P = 0.519). The patients from counties near HNRCCs, showed a 210.8 % increase in appointments overall, 33.8 % of which were at an HNRCC. At the main campus exclusively, the shift in regional patients to HNRCCs coincided with a lower rate of increase in patients from the MDACC service area (33.7 vs. 11.0 patients/year; P = 0.035), but the trend was toward a greater increase in out-of-state patients (25.7 vs. 40.3 patients/year; P = 0.299). CONCLUSIONS: The creation of HNRCCs coincided with stable increases in new patient volume, and a sizeable minority of patients sought care at regional centers. Regional patients shifted to the HNRCCs, and out-of-state patient volume increased at the main campus, optimizing access for both local and out-of-state patients.

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.

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. METHODS: A retrospective case series for clival malignancies operated between 1993 and 2019 was conducted. Inclusion criteria were age over 18 and a follow-up of at least a 6 months. Statistical analyses were conducted using STATA version 15 statistical software package StataCorp. RESULTS: For the whole cohort (113 patients), and for upper and middle lesions, open surgical approaches increased odds of disease progression, compared to EEA (HR 2.10 to HR 2.43), p < 0.05. EEA had a shorter time interval from surgery to initiation of radiotherapy. No difference in 6 and 12 month KPS was found between surgical groups. Patients undergoing open surgery were less likely to achieve GTR for upper clival lesions. CONCLUSIONS: EEA was found to be associated with increased PFS, for upper and middle clival malignancies. The time to initiation of radiotherapy was shorter for patients undergoing EEA compared to open surgery for patients with middle clival involvement. GTR rates were found to be significantly better with EEA for patients with upper clival malignancies.

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. Sinonasal and nasopharyngeal tumors affect patients' quality of life, appearance, and critical functions. Tumors arise in proximity of vital structures including the orbit, cranial nerves, carotid artery, brain, cervical spine, and pituitary gland. Surgical morbidity, along with acute and late effects of systemic therapy and radiotherapy on normal tissues in this functionally critical region, may result in wide-ranging symptoms. Patients with skull base tumors report a high symptom burden at presentation, prior to treatment, relative to other malignancies in the head and neck region.

BACKGROUND: Squamous cell carcinoma is the most common type of sinonasal malignancy. Despite improvements in surgical resection and adjuvant therapy, which are considered the standard of care, the outcome for patients with locoregionally advanced disease remains poor. The objective of this study was to investigate the role of induction chemotherapy in patients with locoregionally advanced sinonasal squamous cell carcinoma and to determine the oncologic outcomes in those patients. METHODS: The study included 123 consecutive patients with previously untreated, locoregionally advanced (stage III and IV) sinonasal squamous cell carcinoma who were treated with curative intent at The University of Texas MD Anderson Cancer Center between 1988 and 2017 with induction chemotherapy followed by definitive local therapy. Patient demographics, tumor staging, treatment details, and oncologic outcomes were reviewed. The outcomes of this study included response to induction chemotherapy, recurrence, organ preservation, and survival. RESULTS: The median follow-up was 32.6 months (range, 12.4-240 months). Of the 123 patients, 110 (89%) had T4 disease, and 13 (11%) had T3 disease. Lymph node metastasis at the time of presentation was observed in 36 patients (29.3%). The overall stage was stage IV in 111 patients (90.2%) and stage III in 12 patients (9.8%). The chemotherapy regimen consisted of the combination of a platinum and taxanes in most cases (109 patients; 88.6%), either as a doublet (41 patients) or in combination with a third agent, such as 5-fluorouracil (34 patients), ifosfamide (26 patients), or cetuximab (8 patients). After induction chemotherapy, 71 patients (57.8%) achieved at least a partial response, and 6 patients had a complete response. Subsequent treatment after induction chemotherapy was either: 1) definitive chemoradiation or radiation followed by surgical salvage for any residual disease, or 2) surgery followed by adjuvant radiation or chemoradiation. Overall, 54 patients (49.5%) underwent surgical resection. The 2-year overall and disease-free survival rates for the whole cohort were 61.4% and 67.9%, respectively. The rate of orbital preservation was 81.5%. The recurrence rate was 26.8% (33 patients), and distant metastases occurred in 8 patients (6.5%). Patients who had at least a partial response or stable disease had significantly better overall and disease-free survival than those who had progressive disease (P = .028 and P = .021, respectively). CONCLUSIONS: The current results indicate that a high proportion of patients with sinonasal squamous cell carcinoma achieved a favorable response to induction chemotherapy. The data suggest that response to induction chemotherapy is associated with an improved outcome and a good chance of organ preservation. The oncologic outcomes in this cohort with locally advanced (mostly T4) disease are better than those historically reported in the literature. Further study of induction chemotherapy in patients with advanced sinonasal squamous carcinoma is warranted.

INTRODUCTION: Sinonasal tumors that harbor neuroendocrine histologic features include olfactory neuroblastoma (previously known as esthesioneuroblastoma), sinonasal neuroendocrine carcinoma, and sinonasal undifferentiated carcinoma. These tumors represent a diverse spectrum of clinical behavior and as such require histology-specific management. Herein, we review the management of these sinonasal tumors with neuroendocrine features and discuss fundamentals of multi-modality care for each histology. An emphasis is placed on olfactory neuroblastomas, given their relative frequency and skullbase origin. METHODS: A comprehensive literature review on contemporary management of olfactory neuroblastoma, sinonasal neuroendocrine carcinoma, and sinonasal undifferentiated carcinoma was performed. RESULTS: Management of sinonasal tumors with neuroendocrine features can include surgical resection, radiation therapy, and/or chemotherapy. Due to their site of origin, these tumors can frequently involve the skullbase, which can require site-specific care. The optimal treatment modalities and the sequence in which they are performed are largely dependent on histology. In most cases, olfactory neuroblastoma is best managed with surgical resection followed by radiation therapy. Sinonasal neuroendocrine carcinomas represent a variety of histologic phenotypes (carcinoid, atypical carcinoid, small cell, and large cell), which determine the optimal treatment modality. Finally, sinonasal undifferentiated carcinoma is likely best managed by induction chemotherapy with subsequent therapy dictated by the initial response. CONCLUSIONS: A team approach to multi-modality care is essential in the treatment of olfactory neuroblastoma, sinonasal neuroendocrine carcinoma, and sinonasal undifferentiated carcinoma. Early biopsy, histologic diagnosis, and comprehensive imaging are critical to determining the appropriate management paradigm.

BACKGROUND: Mucosal melanomas in the head and neck region are most often located in the nasal cavity and paranasal sinuses. To the authors' knowledge, the prognostic effects of lymph node metastasis in patients with sinonasal mucosal melanoma (SNMM) have not been established. Therefore, the objective of the current study was to determine the effects of lymph node metastasis on survival. METHODS: The current study included 198 patients with SNMM who had been treated between 1985 and 2016 at The University of Texas MD Anderson Cancer Center in Houston. Patients' clinical and pathologic lymph node statuses were evaluated and characterized. A multivariate analysis was used to assess the associations between regional spread and survival outcomes. RESULTS: Therapeutic neck dissection was performed in 23 patients with SNMM (11.6%). Regional disease recurrence occurred in 7 of the patients who had lymph node metastasis at the time of presentation (30.4%) and in 30 of those who had N0 disease at the time of presentation (17.1%) (P = .15). Metastasis to the contralateral lymph nodes was present in 7 patients (3.5%). The 5-year disease-specific survival rate was 66% in patients with lymph node spread compared with 45% in patients with N0 status (P = .04, log-rank test). A multivariate analysis demonstrated that distant metastasis was the only variable found to be independently associated with both overall survival (hazard ratio, 2.96; 95% confidence interval, 1.54-6.95 [P = .01]) and disease-specific survival (hazard ratio, 3.32; 95% confidence interval, 1.79-7.14 [P = 0.01]). CONCLUSIONS: The results of the current study demonstrated that lymph node status in patients with SNMM was not a significant predictor of outcome. This finding, together with the low incidence of lymph node metastases in patients with SNMM, suggests that elective treatment of the neck should be highly selective in this patient population.

BACKGROUND: Head and neck mucosal melanoma is a locally aggressive tumor with a high recurrence rate. The paranasal sinuses and nasal cavity are the most common primary tumor sites. OBJECTIVE: The purpose of this retrospective study was to identify independent predictors of outcome in sinonasal mucosal melanoma (SNMM) and characterize the patterns of treatment failure. METHODS: This study included 198 patients with SNMM who had been treated at The University of Texas MD Anderson Cancer Center from 1 January 1991 through 31 December 2016. The survival outcomes included overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), local recurrence-free survival, and distant metastasis-free survival. A stepwise regression analysis was used to assess associations in the multivariate models. RESULTS: The 5-year OS, DSS, and DFS rates were 38, 58, and 27%, respectively. Independent predictors of poor OS and DSS were the paranasal sinuses as the primary tumor site [hazard ratio (HR) 1.73, 95% confidence interval (CI) 1.11-2.66; and HR 2.12, 95% CI 1.21-3.74, respectively] and the presence of distant metastases at presentation (HR 4.53, 95% CI 2.24-7.83; and HR 3.6, 95% CI 1.12-7.1). Recurrence occurred in 96 patients (48%). The most common cause of treatment failure was distant metastasis in 69 of 198 patients (35%), followed by local [36 (18%)] and regional [22 (11%)] recurrence. CONCLUSION: The most common cause of treatment failure in SNMM is distant metastasis. The tumor site and the presence of metastatic disease at presentation were the only independent predictors of survival. These data can be used to inform quality improvement efforts and the counseling of high-risk SNMM patients.

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.

BACKGROUND: Sinonasal mucosal melanoma (SNMM) comprises <1% of all melanomas and lacks well-characterised molecular markers. Our aim was to determine the frequencies of common mutations and examine their utility as molecular markers in a large series of primary SNMMs. METHODS: SNMM patients seen at our institution from August 1991 through July 2016 were identified. Genomic DNA was extracted from 66 formalin-fixed paraffin-embedded tumours and screened for mutations by direct sequencing. We investigated the association of mutations with clinicopathological features and survival outcomes. RESULTS: Overall, 41% (27 out of 66) of the SNMMs harboured mutations. BRAF and KIT mutations were identified in 8% (five patients) and 5% (three patients) of SNMMs, respectively, whereas NRAS mutations were detected in 30% (20 patients) of SNMMs. Mutation rates in these oncogenes were similar between SNMMs located in the paranasal sinuses and those in the nasal cavity (30% and 13%, respectively, P=0.09). In a multivariate analysis, patients with negative margins had significantly better overall survival (hazard ratio 5.43, 95% confidence interval 1.44-21.85, P=0.01) and disease-specific survival (hazard ratio 21.9, 95% confidence interval 3.71-180, P=0.0004). The mutation status of the tumours showed no association with survival outcomes. CONCLUSIONS: In SNNM, mutation status does not affect survival outcomes, but NRAS mutations are relatively frequent and could be targeted in this disease by MEK inhibitors.

Olfactory neuroblastoma (ONB) is a rare malignant tumor. Although the vast majority of cases arise in the nasal cavity, ONB is rarely reported in ectopic locations. We report a case of ONB in the maxillary sinus. A 63-year-old woman presented with left-sided nasal obstruction and epistaxis. Magnetic resonance imaging showed a nonenhancing left maxillary sinus tumor. Histologic sections showed ONB, Hyams grade IV, invading bone, skeletal muscle, and adjacent fibroadipose tissue. It is essential to be accurate when diagnosing sinonasal tumors because the differential diagnosis is broad, and one must consider the possibility of ectopic ONB, although it is rare. The behavior of ONB and other neuroendocrine tumors of the sinonasal region is quite different, and there are varied approaches to treatment. Therefore, an accurate diagnosis as well as correct grade and stage must be assigned.

Sinonasal malignancies, a rare group of tumors, are characterized by histological heterogeneity and poor survival. As improvements in image-guidance and endoscopic technologies became incorporated into head and neck oncologic and neurosurgical practice, the application of these technologies and techniques to the surgical management of sinonasal malignancy began. Over the past decade, there has been increasing evidence regarding the safety and oncological effectiveness of these techniques. Several institutions have reported their experience with endoscopic surgery and have shown reduced morbidity, better quality of life, and survival outcomes equivalent to those of open surgery in carefully selected patients. Endoscopic cranial base surgery is a rapidly evolving field. We review the literature on oncological outcomes, safety, quality of life, and recent technological advances.

OBJECTIVE: Expanded endoscopic approaches (EEAs) are increasingly used for the definitive management of sinonasal malignancies. EEAs, in appropriately selected cases, provide similar oncological outcomes but are associated with lower complication rates compared with open surgical approaches. Selection bias is a limitation reported in previous studies comparing EEAs and open surgical approaches for the management of sinonasal malignancies. To address this issue, in this study the authors compared the long-term oncological outcomes of an anatomically matched cohort of patients with locally advanced sinonasal malignancies with skull base involvement (T4 stage). The specific objective of this study was to investigate the extent of resection (EOR), overall survival (OS), and disease progression between the EEA and open surgical cohorts. METHODS: A cohort of 42 patients with locally advanced sinonasal malignancies and skull base involvement (stage T4) and operated on via an EEA was matched anatomically with a cohort of 54 patients who had undergone open surgery. A retrospective chart review was conducted on these 96 patients who were treated between September 1993 and June 2020. All patients in the cohort were eligible for either an EEA or open surgery according to anatomical criteria. Patients of all ages were included, and the minimum follow-up required for eligibility was 4 months. Patients were excluded if surgery was not offered for curative intent and preoperative imaging did not demonstrate that gross-total resection was achievable. RESULTS: There were more complications in the conventional surgery cohort than in the EEA cohort (33.33% vs 14.29%, p = 0.033). There was no significant difference in the EOR between the EEA and conventional surgery cohorts, as demonstrated by comparable rates of positive margins in both groups (5.56% vs 2.38%, respectively). Disease progression (hazard ratio [HR] 0.47, 95% CI 0.17-1.27, p = 0.137) was lower and OS (HR 0.58, 95% CI 0.26-1.29, p = 0.183) was higher in the EEA cohort, but these findings did not reach statistical significance. CONCLUSIONS: The EEA was found to be associated with lower risks of complications than conventional craniofacial surgical approaches. There were no significant differences in OS and progression-free survival between the EEA and conventional surgical cohorts when comparing anatomically matched cohorts of patients with stage T4 sinonasal malignancies and skull base involvement.

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. RESULTS: Out of 80 patients, 48 had eye-sparing surgery, 8 had orbital exenteration and 24 were managed non-surgically. The most common histology was squamous cell carcinoma (n=28, 35%). Among the eye-sparing treatment group, 51/72 patients experienced one or more orbital/periocular complication(s), with motility deficit (N=26, 36%) being the most frequent. Factors associated with higher risk of complications included tumour involving the orbital floor (p=0.019), clinical disease stage III/IV (p=0.038), maxillectomy (p=0.004), resection of the orbital floor (p=0.027) and cigarette smoking (p=0.041). Tumour involving the orbital floor had an OR of 3.9 (95% CI 1.3 to 11.6, p=0.016) in predicting orbital/periocular complication. In the eye-sparing surgery group, the most frequent secondary oculoplastic procedures was dacryocystorhinostomy (n=6, 13%). The use of a free flap in reconstruction had an OR of 8.2 (95% CI 2.1 to 31.8, p=0.002) in predicting need for secondary oculoplastic surgery. CONCLUSION: Majority of patients with sinonasal tumours and secondary orbital invasion were managed with eye-sparing multidisciplinary treatments. Preservation of the eye can lead to reasonably good functional outcome despite expected orbital and periocular complications.

BACKGROUND: Sinonasal NUT carcinoma is an extremely rare, lethal malignancy with limited literature. METHODS: A case series was conduction of all patients with sinonasal NUT carcinoma at a single institution between 2010 and 2022. Survival and associated were evaluated. A systematic review of the literature was performed. RESULTS: In 12 patients, followed for a median of 1.5 years, the median overall survival (OS) and disease-specific survival (DSS) were both 14.6 months. Patients with maxillary sinus tumors were 91% more likely to survive (hazard ratio [HR]: 0.094, 95% confidence interval [CI]: 0.011-0.78, p = 0.011). Patients with higher-stage disease stage had worse OS (stage IVb-c vs. III-IVa, p = 0.05). All three patients who were alive with no evidence of disease received induction chemotherapy. CONCLUSION: For patients with sinonasal NUT carcinoma, the median survival was 15 months but better with lower-stage and maxillary tumors. Induction chemotherapy may be beneficial.

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. Tumor control, survival, and patient-reported quality of life were analyzed. RESULTS: Fourteen patients with 32 dural lesions were evaluated. Time to dural recurrence was 58.3 months. Thirty lesions (94%) were treated with SBRT to a median dose of 27 Gy in three fractions. Two patients (3 of 32 lesions; 9%) developed in-field radiographic progression, five patients (38%) experienced progression in non-contiguous dura. Two-year local control was 85% (95% CI: 51-96%). There were no >grade 3 acute toxicities and 1 case of late grade 3 brain radionecrosis. CONCLUSION: In this largest study of SBRT reirradiation for ONB dural recurrence to date, high local control rates with minimal toxicity were attainable.
RESUMO
BACKGROUND: Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field. METHODS: In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication. RESULTS: The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention. CONCLUSION: As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

BACKGROUND: The current study presents the effort of a global collaborative group to review the management and outcomes of malignant tumors of the skull base worldwide. PATIENTS AND METHODS: A total of 28 institutions contributed data on 3061 patients. Analysis evaluated clinical variables, survival outcomes, and multivariable factors associated with outcomes. RESULTS: The median age was 56 years (IQR 44-67). The open surgical approach was used in 55% (n = 1680) of cases, endoscopic resection was performed in 36% (n = 1087), and the combined approach in 9.6% (n = 294). With a median follow-up of 7.1 years, the 5-year OS DSS and RFS were 65%, 71.7% and 53%, respectively. On multivariable analysis, older age, comorbidities, histology, dural/intracranial involvement, positive margins, advanced stage, and primary site were independent prognostic factors for OS, DSS, and RFS. Adjuvant RT was a protective prognostic factor. CONCLUSION: The progress across various disciplines may have contributed to improved OS and DSS in this study compared to previous reports.
RESUMO
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. RECENT FINDINGS: Recent publications highlight the role of induction chemotherapy and advances in radiotherapy in advanced cancers. In addition, better understanding of genomics and histology specific treatment algorithms has led to more tailored treatment approaches. The role of immunotherapy and targeted therapy are yet to be explored. SUMMARY: This review gives an up to date summary of the advances in contemporary management strategies for locally advanced sinonasal malignancies and can serve as a guide for researchers and clinicians.
