RESUMO
Sinonasal malignancies make up <5% of all head and neck neoplasms, with an incidence of 0.5-1.0 per 100,000. The outcome of these rare malignancies has been poor, whereas significant progress has been made in the management of other cancers. The objective of the current review was to describe the incidence, causes, presentation, diagnosis, treatment, and recent developments of malignancies of the sinonasal tract. The diagnoses covered in this review included sinonasal undifferentiated carcinoma, sinonasal adenocarcinoma, sinonasal squamous cell carcinoma, and esthesioneuroblastoma, which are exclusive to the sinonasal tract. In addition, the authors covered malignances that are likely to be encountered in the sinonasal tract-primary mucosal melanoma, NUT (nuclear protein of the testis) carcinoma, and extranodal natural killer cell/T-cell lymphoma. For the purpose of keeping this review as concise and focused as possible, sarcomas and malignancies that can be classified as salivary gland neoplasms were excluded.

BACKGROUND: This study investigated the influence of oral microbial features on the trajectory of oral mucositis (OM) in patients with squamous cell carcinoma of the head and neck. METHODS: OM severity was assessed and buccal swabs were collected at baseline, at the initiation of cancer treatment, weekly during cancer treatment, at the termination of cancer treatment, and after cancer treatment termination. The oral microbiome was characterized via the 16S ribosomal RNA V4 region with the Illumina platform. Latent class mixed-model analysis was used to group individuals with similar trajectories of OM severity. Locally estimated scatterplot smoothing was used to fit an average trend within each group and to assess the association between the longitudinal OM scores and longitudinal microbial abundances. RESULTS: Four latent groups (LGs) with differing patterns of OM severity were identified for 142 subjects. LG1 has an early onset of high OM scores. LGs 2 and 3 begin with relatively low OM scores until the eighth and 11th week, respectively. LG4 has generally flat OM scores. These LGs did not vary by treatment or clinical or demographic variables. Correlation analysis showed that the abundances of Bacteroidota, Proteobacteria, Bacteroidia, Gammaproteobacteria, Enterobacterales, Bacteroidales, Aerococcaceae, Prevotellaceae, Abiotrophia, and Prevotella_7 were positively correlated with OM severity across the four LGs. Negative correlation was observed with OM severity for a few microbial features: Abiotrophia and Aerococcaceae for LGs 2 and 3; Gammaproteobacteria and Proteobacteria for LGs 2, 3, and 4; and Enterobacterales for LGs 2 and 4. CONCLUSIONS: These findings suggest the potential to personalize treatment for OM. PLAIN LANGUAGE SUMMARY: Oral mucositis (OM) is a common and debilitating after effect for patients treated for squamous cell carcinoma of the head and neck. Trends in the abundance of specific microbial features may be associated with patterns of OM severity over time. Our findings suggest the potential to personalize treatment plans for OM via tailored microbiome interventions.

Adenocarcinomas of the nasal/paranasal sinuses are uncommon, but intestinal-type adenocarcinomas (ITACs) are important. Due to the rarity of these tumors, their molecular profile is not well known. To further investigate the molecular profile and find potential oncogenic drivers, we compared the whole transcriptome and exome of ITACs at different anatomic locations in the head and neck. Twenty-one head and neck adenocarcinomas were used in this study, divided into 10 sinonasal adenocarcinomas (SNT) and 11 extrasinonasal (T) head and neck adenocarcinomas according to anatomic location and histology. Tumor samples along with normal mucosa were microdissected from formalin-fixed, paraffin-embedded samples, and RNA and DNA were subjected to whole-transcriptome and -exome shotgun sequencing. Analysis of ITACs at sinonasal locations showed 410 subtype-specific differentially expressed (DE) genes and noncoding transcripts compared with the group of other anatomic locations, with 2909 subtype-specific DE genes. The groups shared 872 genes, with 17 highly different or opposing DE genes. Whole-exome mutation analysis revealed the gene MLL3 (KMT2C) to be exhibiting the most frequent loss-of-function mutations in all adenocarcinomas investigated. The results suggest that the head and neck ITACs investigated were mainly caused by loss-of-function mutations in MLL3 that disabled chromatin methylation and remodeling of all MLL3-targeted enhancers in the tumors. This changed the activity of multiple genes/gene clusters, supporting oncogenicity mostly via pathways of signaling, dedifferentiation, proliferation, migration, and immune and inflammatory deregulation, indicating a truly epigenetic event as the root cause for the heterogenous diversity of these enteric types of cancer. The data of this study form the basis for understanding cell fate determination and cellular homeostasis in the normal respiratory mucosa at different anatomic sites and show the contribution of different mucosal components to the etiology/molecular pathology of ITAC.

B7-H4 (VTCN1), a member of the B7 family, is overexpressed in several types of cancer. Here we investigated the pattern of expression of B7-H4 in salivary gland carcinomas (SGC) and assessed its potential as a prognostic marker and therapeutic target. Immunohistochemistry (IHC) analyses were performed in a cohort of 340 patient tumors, composed of 124 adenoid cystic carcinomas (ACC), 107 salivary duct carcinomas (SDC), 64 acinic cell carcinomas, 36 mucoepidermoid carcinomas (MEC), 9 secretory carcinomas (SC), as well as 20 normal salivary glands (controls). B7-H4 expression was scored and categorized into negative (<5% expression of any intensity), low (5%-70% expression of any intensity or >70% with weak intensity), or high (>70% moderate or strong diffuse intensity). The associations between B7-H4 expression and clinicopathologic characteristics, as well as overall survival, were assessed. Among all tumors, B7-H4 expression was more prevalent in ACC (94%) compared with those of SC (67%), MEC (44%), SDC (32%), and acinic cell carcinomas (0%). Normal salivary gland tissue did not express B7-H4. High expression of B7-H4 was found exclusively in ACC (27%), SDC (11%), and MEC (8%). In SDC, B7-H4 expression was associated with female gender (P = .002) and lack of androgen receptor expression (P = .012). In ACC, B7-H4 expression was significantly associated with solid histology (P < .0001) and minor salivary gland primary (P = .02). High B7-H4 expression was associated with a poorer prognosis in ACC, regardless of clinical stage and histologic subtype. B7-H4 expression was not prognostic in the non-ACC SGC evaluated. Our comparative study revealed distinct patterns of B7-H4 expression according to SGC histology, which has potential therapeutic implications. B7-H4 expression was particularly high in solid ACC and was an independent prognostic marker in this disease but not in the other SGC assessed.

PURPOSE OF REVIEW: To highlight recent and relevant treatment considerations while managing mucosal melanoma. RECENT FINDINGS: Evidence is building to support the use of targeted therapy and immunotherapy while managing mucosal melanoma. Surgical resection with postoperative radiotherapy plays a major role in managing resectable disease. Recent studies evaluate the addition of targeted, and immunotherapies with an attempt to determine the most efficacious sequence of treatment.

PURPOSE OF REVIEW: The purpose of review is to provide a comprehensive review of the literature focusing on the recent advances in the diagnosis, molecular underpinning, and targeted therapy of olfactory neuroblastoma (ONB). RECENT FINDINGS: Studies focused on the molecular fingerprinting of ONB are critical to engage new promising treatment strategies. Molecular-based subtype classifications have been proposed (basal-like ONB and neural-like ONB) but are not widely used. The rationale for implementation of DNA methylation analysis and IDH2 sequencing in routine work-up for ONB is gaining recognition. Expression of somatostatin receptors (SSTR) in ONB open new avenues for both, diagnostic (especially metastatic disease) and new treatment protocols with somatostatin analogs. Olfactory carcinoma is proposed as a unifying diagnostic terminology pertinent to epithelial divergent differentiation in olfactory neuroblastoma. Molecular (genetic and epigenetic) efforts on olfactory neuroblastoma are promising; however further refinement is needed for employment of these biomarkers as clinical standard of care. Ongoing and future multi-institutional collaborative studies will contribute to further understanding of ONB biology and aid the development of targeted treatments for this disease.

PURPOSE OF REVIEW: Identification of neuroendocrine (NE) differentiation is critical to the classification of head and neck (HN) and lung tumors. In combination with tumor morphology, immunohistochemical (IHC) documentation of NE differentiation is necessary for the diagnosis of NE tumors. The purpose of this study is to determine the sensitivity and concordance of two novel NE markers (mASH1, INSM1) across a group of high-grade NE tumors of the sinonasal tract and lung, and to compare their expression with the current widespread use of conventional NE markers, synaptophysin (SYN) and chromogranin A (CGA). In addition, expression of PARP1 is examined as a potential novel therapeutic target. RECENT FINDINGS: Thirty-nine high-grade NE tumors, 23 of the HN and 16 of the lung, were reevaluated by two subspecialized HN and thoracic pathologists, and subsequently stained with mASH1, INSM1, and PARP1. Sensitivity and degree of concordance of all possible combinations of markers were assessed. Sensitivities (standard error) were as follows: mASH1 41% (0.08), INSM1 44% (0.08), SYN 56% (0.08), and CGA 42% (0.09); combination of all four NE markers: 73% (0.08). Sensitivity and standard error for PARP1 was 90% and 0.05, respectively. Highest sensitivity to detect NE differentiation in high-grade NE tumors of the HN and thoracic region was achieved with a combination of four NE markers. Moderate concordance was found with combinations of mASH1 and INSM1 and traditional NE markers, respectively. Consistent overexpression of PARP1 in high-grade tumors with NE differentiation in the HN and lung opens eligibility for PARP1 inhibitor trials.

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.

BACKGROUND: Salivary duct carcinoma (SDC) and adenocarcinoma, not otherwise specified (adeno-NOS), are rare salivary gland cancers. Data on the efficacy of systemic therapy for these diseases are limited. METHODS: Data were retrospectively collected from patients seen at The University of Texas MD Anderson Cancer Center during 1990 to 2020. Objective response rate (ORR) was assessed per RECIST v1.1. Recurrence-free survival (RFS), progression-free survival (PFS), and overall survival (OS) were assessed by Kaplan-Meier method. Cox regression model was performed to identify predictors of survival. RESULTS: The analysis included 200 patients (110 with SDC and 90 with adeno-NOS); 77% had androgen-receptor-positive tumors and 47% had HER2-positive (2+-3+) tumors. Most patients without metastasis at diagnosis underwent surgery (98%) and postoperative radiotherapy (87%). Recurrence rate was 55%, and the median RFS was 2 years. Nodal involvement and positive surgical margins were associated with recurrence (P < .005). Among patients with stage IVA-B disease, addition of systemic therapy to local therapy increased OS (P = .049). The most-used palliative-systemic-therapy regimen was platinum doublet ± trastuzumab. For first-line therapy, the ORR and median PFS were 33% and 5.76 months, respectively, and for second-line therapy the ORR and median PFS were 25% and 5.3 months, respectively. ORR and PFS were higher with HER2-targeting agents. Median OS was 5 years overall and 2 years for metastatic disease. Older age and higher stage were associated with worse OS. CONCLUSION: Adding systemic therapy to local therapy may improve outcomes of patients with locoregionally advanced SDC or adeno-NOS. Except for HER2-targeted therapy, response to palliative systemic therapy is limited. These findings may be used as a benchmark for future drug development.

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.

Biphenotypic sinonasal sarcoma (BSNS) is a recently described spindle cell sarcoma with neural and myogenic differentiation which arises exclusively in the sinonasal region. A man presented with swelling of left eyelid, and history of resection of a low-grade spindle cell mesenchymal tumor of left sinonasal cavity performed 15 years before. The original diagnosis was synovial sarcoma. Current MRI showed left supraorbital mass with intracranial extension. IR biopsy confirmed recurrence, and a left orbital craniotomy was done. NGS identified PAX3-MAML3 fusion in both, current and original tumor. The sarcoma was reclassified as BSNS, recurrent, with higher grade transformation. While the morphology, phenotype and molecular signature were in keeping with BSNS, the tumor showed biological progression towards a high-grade sarcoma. High-grade transformation of low-grade BSNS has not been described so far. High-grade transformation was not appreciated at the time of initial diagnosis, and it occurred in the local recurrence 15 years after.

BACKGROUND: Carotid blowout syndrome (CBS) is an infrequent but dangerous oncologic emergency that must be recognized due to a mortality rate that approaches 40% and neurologic morbidity that approaches 60%. Patients present with a variety of symptoms ranging from asymptomatic to frank hemorrhage, and appropriate recognition and management may improve their outcomes. CASE REPORT: A man in his late 60s with squamous cell carcinoma of the oropharynx presented to the emergency department (ED) with hemoptysis and several episodes of post-tussive emesis with large clots. He had been cancer free for multiple years after treatment with chemotherapy and radiation to the neck. Evaluation revealed a necrotic tumor on the posterior pharynx on bedside laryngoscopy and an external carotid pseudoaneurysm that was stented by interventional radiology. The patient experienced recurrent hemorrhage several months later and opted for palliative measures and expired of massive hemorrhage in the ED on a subsequent visit. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: CBS can be fatal, and early suspicion and recognition are key to ensure that a threatened or impending carotid blowout are appropriately managed. Once carotid blowout is suspected, early resuscitation and consultation with interventional radiology and vascular surgery is warranted.

BACKGROUND: Patients with locoregionally advanced oral cavity squamous cell carcinoma (OCSCC) have a poor survival outcome. Treatment involves extensive surgery, adjuvant radiation, or chemoradiation and results in high morbidity. In this study, the authors' objective was to evaluate their experience with induction chemotherapy (IC) in the treatment of locoregionally advanced OCSCC. METHODS: A retrospective review of the medical records of all patients with locoregionally advanced (stage III and IV) OCSCC who received IC followed by definitive local therapy was conducted. Outcomes included response to IC and survival. RESULTS: In total, 120 patients were included in the study. The overall stage was stage IV in 79.2% of patients. After 2 cycles of IC, 76 patients (63.3%) achieved at least a partial response, including 13 who had a complete response. Stable disease was observed in 30 patients (25%), and 14 patients (11.7%) had progressive disease. Among responders, 16 patients received definitive chemoradiation or radiation therapy, and 60 underwent surgical resection, of whom 15 had less extensive surgery than was originally planned. Overall, organ preservation was achieved in 40.8% of patients who had a favorable response to IC. The 5-year overall and disease-specific survival rates were 51.4% and 66.9%, respectively. Patients who had at least a partial response had better 5-year overall survival (60.1%) and disease-specific survival (78.5%) compared with nonresponders (33.8% and 46.4%, respectively). CONCLUSIONS: The results demonstrate a response rate to IC in patients with advanced OCSCC similar to what has been observed in patients with cancer in other head and neck subsites. Patients who achieved at least a partial response to IC had a more favorable outcome, with ensuing organ preservation. Further studies are warranted.

BACKGROUND: Orbital exenteration (OE) is an ablative procedure used in the management of malignancies of the orbit of either primary or secondary origin. Publications evaluating this procedure have suffered from small patient numbers, heterogeneity of pathologies, and poor patient follow-up. The purpose of this study was to assess patient outcomes in a large cohort of patients undergoing OE at a tertiary cancer center. METHODS: A retrospective review was conducted of 180 consecutive patients who underwent OE at the authors' institution. Overall survival (OS) was the primary end point measured in the study. Time to locoregional recurrence (progression-free survival [PFS]) and disease-free survival were secondary end points. RESULTS: Between the years 1993 and 2011, 180 consecutive patients received OE for craniofacial malignancy at the authors' institution. The median follow-up for the cohort was 9.7 years (116 months). The median OS was 73 months, and the median PFS was 96 months. The presence of perineural invasion was associated with shorter OS (P = .01) and PFS (P < .01). Magnetic resonance imaging was predictive of perineural invasion (P < .01). Positive margins were associated with shorter PFS than negative margins (P < .01) but with no change in OS (P = .15). The overall complication rate was 15%. The major complication rate (Clavien-Dindo 3b or greater) was 2.8% (n = 5), and there was 1 death observed (0.6%). CONCLUSIONS: Used judiciously in the setting of a multidisciplinary management plan, OE for tumor control is a safe therapy. LAY SUMMARY: Between the years 1993 and 2011, 180 consecutive patients received orbital exenteration for craniofacial malignancy at the MD Anderson Cancer Center. The median follow-up for the cohort was 9.7 years. The presence of perineural invasion was associated with shorter overall survival (P = .01) and progression-free survival (P < .01). Magnetic resonance imaging was predictive of perineural invasion (P < .01). Positive margins were associated with shorter progression-free survival than negative margins (P < .01). The overall complication rate was 15%. The major complication rate (Clavien-Dindo 3b or greater) was 2.8% (n = 5).

BACKGROUND: Prior research has confirmed that persistent hypomagnesemia was predictive of shorter survival among patients with ovarian cancer who received carboplatin-based chemotherapy. In the current retrospective study, the authors examined the association between hypomagnesemia and survival in patients with head and neck cancer who received concurrent chemoradiation with weekly infusions of cisplatin and/or carboplatin. METHODS: Patients with head and neck cancers who had undergone chemoradiation with cisplatin and/or carboplatin between January 1, 2010, and December 31, 2014, were included. Patients were aged ≥18 years with pathology of squamous cell carcinoma of the larynx, oral cavity, or oropharynx who had received at least 30 fractions of radiotherapy with concurrent weekly cisplatin and/or carboplatin. Pathology features, laboratory results, Eastern Cooperative Oncology Group performance status, social histories, and survival were recorded. The association between hypomagnesemia and survival was analyzed controlling for known prognostic factors. RESULTS: The final cohort consisted of 439 patients with a median age of 59 years. A greater frequency of hypomagnesemia during the treatment course was found to be significantly associated with shorter survival (hazard ratio [HR], 1.13; P = .033) independent of age (HR, 1.65; P = .042), cancer site (nonoropharynx vs oropharynx: HR, 2.15 [P = .003]), Eastern Cooperative Oncology Group performance status (>1 vs ≤1: HR, 2.64 [P < .001]), and smoking history (smoker vs nonsmoker: HR, 1.88 [P = .012]). In addition, more severe hypomagnesemia was associated with shorter survival compared with the milder form. CONCLUSIONS: The frequency and severity of hypomagnesemia during treatment are prognostic of survival for patients with head and neck cancers who are receiving concurrent chemoradiation with cisplatin and/or carboplatin. A prospective study is needed to investigate the impact of the prevention of hypomagnesemia on survival in this patient population.

BACKGROUND: This study was conducted to identify clinicodemographic risk factors for xerostomia among long-term oropharyngeal cancer (OPC) survivors. METHODS: This cross-sectional study included 906 disease-free, adult OPC survivors with a median survival duration at the time of survey of 6 years (range, 1-16 years); self-reported xerostomia scores were available for 877 participants. Study participants had completed curative treatment between January 2000 and December 2013 and responded to a survey administered from September 2015 to July 2016. The primary outcome variable was cancer patient-reported xerostomia measured with the MD Anderson Symptom Inventory Head and Neck Cancer Module. Clinicodemographic risk factors for moderate to severe xerostomia were identified via multivariable logistic regression. RESULTS: Moderate to severe xerostomia was reported by 343 of the respondents (39.1%). Female sex (odds ratio [OR], 1.82; 95% CI, 1.22-2.71; P = .003; Bayesian false-discovery probability [BFDP] = 0.568), high school or lower education (OR, 1.73; 95% CI, 1.19-2.52; P = .004; BFDP = 0.636), and current cigarette smoking at the time of survey (OR, 2.56; 95% CI, 1.19-5.47; P = .016; BFDP = 0.800) were risk factors for moderate to severe xerostomia, and bilateral intensity-modulated radiotherapy (IMRT) combined with proton therapy and ipsilateral IMRT were protective. CONCLUSIONS: In this large xerostomia study, modern radiotherapy was a protective factor, and continued cigarette smoking at the time of survey, female sex, and high school or lower education were identified as other contributing risk factors associated with moderate to severe xerostomia. Importantly, these findings need to be confirmed in prospective studies. These results can inform future research and targeted patient-centered interventions to monitor and manage radiation therapy-associated xerostomia and preserve quality of life among patients with OPC.

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.
