Squamous cell carcinoma of the nasal vestibule in the Netherlands: A clinical and epidemiological review of 763 cases (2008-2021). Head Neck 2024. [PMID: 38511478 DOI: 10.1002/hed.27749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 03/12/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND Squamous cell carcinoma of the nasal vestibule (SCCNV) is a rare disease, distinctly different in presentation, treatment, and outcome from squamous cell carcinoma (SCC) of the nasal cavity and paranasal sinuses. However, these are often not analyzed separately. METHODS The Netherlands Cancer Registry (NCR) and pathology reports from the Dutch Nationwide Pathology Databank (PALGA) were used to identify all newly diagnosed SCCNV cases in the Netherlands between 2008 and 2021. RESULTS A total of 763 patients were included. The yearly incidence rate displayed a significant downward trend with an annual percentage change (APC) of -3.9%. The 5-year overall survival (OS) and disease-free survival were 69.0% and 77.2%, respectively. The 5-year relative survival was 77.9% and improved slightly over the inclusion period. OS for patients who were staged cT3 appeared to be worse than those staged cT4a, calling the applicability of the TNM-classification into question. CONCLUSION SCC of the nasal vestibule is rare, with declining incidence rates. Introducing a specific topography code for SCCNV is recommended to enhance registration accuracy. The TNM classification seems poorly applicable to SCCNV, suggesting the need to explore alternative staging methods.

Validation of the "Rome" Classification for Squamous Cell Carcinoma of the Nasal Vestibule. Cancers (Basel) 2023; 16:37. [PMID: 38201465 PMCID: PMC10778048 DOI: 10.3390/cancers16010037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/14/2023] [Accepted: 12/15/2023] [Indexed: 01/12/2024] Open
Abstract
Squamous cell carcinoma of the nasal vestibule is considered a rare malignancy that differs from other sinonasal malignancies in many respects. Four staging systems currently exist for this disease, the most recent addition being the "Rome" classification. This study assesses the use of this new classification and its prognostic value regarding various outcome measures. A retrospective multicenter cohort study of patients with a primary squamous cell carcinoma of the nasal vestibule who were treated in three tertiary head and neck oncology referral centers was conducted. A total of 149 patients were included. The median follow-up duration was 27 months. Five-year locoregional control (LRC), disease-specific survival (DSS), and overall survival (OS) were 81.6%, 90.1, and 62.5% respectively. A statistically significant association was observed between the Rome classification and all survival outcomes in both univariable and multivariable analyses. Moreover, it appeared to perform better than the Union for International Cancer Control TNM classification for tumors of the nasal cavity and paranasal sinuses. The new Rome classification can be used effectively and is associated with LRC, DSS, and OS. However, it requires further validation in a larger (prospective) study population.

Interventional Radiotherapy (Brachytherapy) for Nasal Vestibule: Novel Strategies to Prevent Side Effects. J Clin Med 2023; 12:6154. [PMID: 37834798 PMCID: PMC10573955 DOI: 10.3390/jcm12196154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 09/18/2023] [Accepted: 09/22/2023] [Indexed: 10/15/2023] Open
Abstract
Interventional radiotherapy (brachytherapy) has become the new therapeutic standard in the management of early stages nasal vestibule tumors; in fact it allows for high local control rates and low toxicity profiles. However, since more and more patients will receive interventional radiotherapy (brachytherapy) as primary treatment, it is desirable to implement novel strategies to reduce the dose to organs at risk with the future aim to result in further lowering long-term side effects. MATERIALS AND METHODS We were able to identify two different strategies to reduce dose to the treatment volume, including the implantation technique (the implant can be interstitial, endocavitary or mixed and the catheters may be placed either using the Paris system rules or the anatomical approach) and the dose distribution within the implant (the most commonly used parameter to consider is the dose non-uniformity ratio). We subsequently propose two novel strategies to reduce dose to organs at risk, including the use of metal shields for fixed organs as in the case of the eyes and the use of a mouth swab to push away mobile organs, such in the case of the mandible. We used two different algorithms to verify the values namely the TG-43 and the TG-186. RESULTS We provided an accurate literature review regarding strategies to reduce toxicity to the treatment volume, underlining the pros and cons of all implantation techniques and about the use dose non-uniformity ratio. Regarding the innovative strategies to reduce the dose to organs at risk, we investigated the use of eye shielding and the use of swabs to push away the mandible by performing an innovative calculation using two different algorithms in a series of three consecutive patients. Our results show that the dose reduction, both in the case of the mandible and in the case of eye shielding, was statistically significant. CONCLUSION Proper knowledge of the best implantation technique and dose non-uniformity ratio as highlighted by existing literature is mandatory in order to reduce toxicity within the treatment volume. With regard to the dose reduction to the organs at risk we have demonstrated that the use of eye shielding and mouth swab could play a pivotal role in clinical practice; in fact, they are effective at lowering the doses to the surrounding organs and do not require any change to the current clinical workflow.

Abstract
Squamous cell carcinoma of the nasal vestibule is reported to account for less than one percent of all head and neck malignancies. It lacks a designated WHO ICD-O topography code, and multiple systems are available for the staging of this disease, which results in unwanted variability and the subsequent poor reliability of data. The aim of this study was to evaluate the currently available staging systems for cancer of the nasal vestibule, including the recently introduced classification by Bussu et al., which built on Wang's original concept but with clearer anatomical cutoffs. Different staging systems for cancer of the nasal vestibule (UICC nasal cavity, UICC skin cancer of the head and neck, Wang and Bussu et al.) were evaluated via a retrospective analysis of 148 patients. The staging system, per Bussu et al., had the most balanced allocation of patients among the stages. When using the Wang classification as a reference, stage migration occurred less frequently with the Bussu classification. The widespread adoption of a single staging system, as well as the introduction of a designated topography code for cancer of the nasal vestibule, could lead to more uniformity in data reporting and improve an understanding of the incidence and disease outcome. The newly proposed carcinoma of the nasal vestibule classification by Bussu et al. has the potential to improve the staging and allocation among stages. Further analysis of survival data is needed to assess which classification system is best suited for nasal vestibule carcinoma.

Abstract
PURPOSE Cancer of the nasal vestibule is a rare type of malignancy constituting less than one percent of all head and neck cancers. These tumors are typically diagnosed at an early stage. Both surgery and radiotherapy provide excellent oncological results, but esthetic results are better after radiotherapy. The aim of this study was to evaluate the long-term oncological follow-up after brachytherapy for early stage squamous cell carcinoma of the nasal vestibule. METHODS AND MATERIALS Retrospective analysis of patients with carcinoma of the nasal vestibule who were treated with primary brachytherapy in the Utrecht University Medical Center. RESULTS In this single center experience over a 17-year period 68 patients with early stage squamous cell carcinoma of the nasal vestibule were treated with brachytherapy. Two patients had lymph node metastases at first clinical presentation. Median follow-up duration was 46.5 months. Five-year locoregional recurrence-free survival, disease-specific survival, and overall survival were 91.1%, 96.1%, and 66.2%, respectively. All recurrences occurred within the first 3 years of follow-up. CONCLUSIONS Brachytherapy offers excellent oncological outcomes and is a safe and effective treatment for early stage carcinoma of the nasal vestibule. Recurrences typically occur within 3 years after treatment.

Carbon Ion Beam Boost Irradiation in Malignant Tumors of the Nasal Vestibule and the Anterior Nasal Cavity as an Organ-Preserving Therapy. Front Oncol 2022; 12:814082. [PMID: 35242709 PMCID: PMC8886023 DOI: 10.3389/fonc.2022.814082] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 01/19/2022] [Indexed: 11/20/2022] Open
Abstract
Background Surgery and radiotherapy are current therapeutic options for malignant tumors involving the nasal vestibule. Depending on the location, organ-preserving resection is not always possible, even for small tumors. Definitive radiotherapy is an alternative as an organ-preserving procedure. Carbon ion beam radiotherapy offers highly conformal dose distributions and more complex biological radiation effects eventually resulting in optimized normal tissue sparing and improved outcome. The aim of the current study was to analyze toxicity, local control (LC), and organ preserving survival (OPS) after irradiation of carcinoma of the nasal vestibule with raster-scanned carbon ion radiotherapy boost (CIRT-B) combined with volumetric intensity modulated arc therapy (VMAT) with photons. Methods Between 12/2015 and 05/2021, 21 patients with malignant tumors involving the nasal vestibule were irradiated with CIRT-B combined with VMAT and retrospectively analyzed. Diagnosis was based on histologic findings. A total of 17 patients had squamous cell carcinoma (SCC) and 4 had other histologies. In this series, 10%, 67%, and 24% of patients had Wang stages 1, 2, and 3 tumors, respectively. Three patients had pathologic cervical nodes on MRI. The median CIRT-B dose was 24 Gy(RBE), while the median VMAT dose was 50 Gy. All patients with pathologic cervical nodes received simultaneously integrated boost with photons (SIB) up to a median dose of 62.5 Gy to the pathological lymph nodes. Eight patients received cisplatin chemotherapy. All patients received regular follow-up imaging after irradiation. Kaplan–Meier estimation was used for statistical assessment. Results The median follow-up after irradiation was 18.9 months. There were no common toxicity criteria grade 5 or 4 adverse events. A total of 20 patients showed grade 3 adverse events mainly on skin and mucosa. All patients were alive at the end of follow-up. The median OPS after treatment was 56.5 months. The 6- and 24-month OPS were 100% and 83.3%, respectively. All local recurrences occurred within 12 months after radiotherapy. The median progression free survival (PFS) after treatment was 52.4 months. The 6-, 12-, and 24-month PFS rates were 95%, 83.6%, and 74.3%, respectively. Conclusion CIRT-B combined with VMAT in malignant tumors of the nasal vestibule is safe and feasible, results in high local control rates, and thus is a good option as organ-preserving therapy. No radiation-associated grade 4 or 5 acute or late AE was documented.

Abstract
BACKGROUND Cancer of the nasal vestibule is a rare type of malignancy dominated by squamous cell carcinoma (SCC), and with poor survival. The treatment is either radiotherapy, surgery or a combination of both. Previous studies have shown a 5-year disease-specific survival of 74% and overall survival (OS) of 50%.Our objective was to describe the consecutive cohort of patients diagnosed with SCC of the nasal vestibule in Denmark from 2008 until 2018 and evaluate prognostic factors and treatment outcome using locoregional failure (LRF), disease-specific mortality (DSM), and OS as endpoints. METHODS All patients diagnosed with SCC of the nasal vestibule from 2008 until 2018 were identified in the nationwide clinical database, DAHANCA and were followed for LRF and death (DSM and OS) until March 2021. OS was analysed using Kaplan-Meier estimator, and cumulative incidence of LRF and DSM were analysed using the Aalen-Johansen estimator. Analysis of prognostic factors was performed using Cox proportional hazard models. RESULTS A total of 162 patients were identified. The median age was 71 years and 54% were male. Disease stage at the time of diagnosis were stage I (70%), II (17%), III (2%) and IV (11%). Curatively intended treatment was performed in 146 patients (90%), of which treatment failure occurred in 42 patients (29%). Most failures occurred at the primary tumour site (64%). Cancer Patient Pathways recommended time to treatment was fulfilled in 71% of patients. The 5-year OS and DSM in patients treated with curative intent were 65% and 11%, respectively. Stage was a significant independent prognostic factor. No difference in LRF, DSM or OS were shown between the applied treatments. CONCLUSIONS Stage is the main independent prognostic factor, and failure most commonly appear at the primary tumour site.

Czerwinski MD, Jansen PP, Zwijnenburg EM, Al-Mamgani A, Vergeer MR, Langendijk JA, Wesseling FWR, Kaanders JHAM, Verhoef CG. Radiotherapy as nose preservation treatment strategy for cancer of the nasal vestibule: The Dutch experience. Radiother Oncol 2021; 164:20-26. [PMID: 34487765 DOI: 10.1016/j.radonc.2021.08.018] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 07/19/2021] [Accepted: 08/25/2021] [Indexed: 01/13/2023]
Abstract
BACKGROUND AND PURPOSE Primary radiotherapy is often preferred for early-stage cancer of the nasal vestibule (CNV), combining high disease control with preservation of nasal anatomy. However, due to practice variation and an absence of comparative trials, no consensus exists on preference for brachytherapy (BT) or external beam radiotherapy (EBRT). We compared these modalities in terms of disease control, nose preservation rates and toxicity. MATERIALS AND METHODS Medical records of 225 patients with T1-T2 squamous cell carcinoma of the nasal vestibule treated with 3D image-guided primary radiotherapy between Jan 2010 and Dec 2016 in 6 Dutch institutions were reviewed retrospectively. RESULTS 153 of 225 patients were treated with BT, 65 with EBRT and 7 with other modalities. Median follow-up was 46 months. Overall 3-year local control (LC) and regional control (RC) were 87% and 89%. Five-year disease-specific survival (DSS) and overall survival (OS) were 94% and 82%. Three-year survival with preserved nose (SPN) was 76%. BT provided higher 3-year LC (95% vs 71%, p < 0.01) and SPN compared with EBRT (82% vs 61%, p < 0.01). Multivariable and propensity-score-matched cohort analyses confirmed better outcomes after BT. No difference was seen in DSS or OS. Five-year incidence of CTCAE 5.0 grade ≥2 toxicity was higher after BT (20% vs 3%, p = 0.03) and consisted mostly of radiation ulcers. 50% of all late toxicity recovered. CONCLUSION In this largest-to-date multicenter analysis of T1-T2 CNV, BT achieved superior LC and SPN compared with EBRT. Grade 1-2 radiation ulcers occurred more frequently after brachytherapy, but were transient in half the cases. Considering these results, BT can be recommended as first-line treatment for T1-T2 CNV.

A single centre's experience of 23 cases of total rhinectomy for the treatment of squamous cell carcinoma involving the nasal vestibule. Eur Arch Otorhinolaryngol 2021; 279:2069-2075. [PMID: 34223976 DOI: 10.1007/s00405-021-06972-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Accepted: 06/27/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE This study aims to analyse the oncological outcomes of total rhinectomy (TR) for squamous cell carcinomas (SCCs) involving the nasal vestibule, and to identify prognostic factors for disease recurrence. METHODS A retrospective single-centre study was conducted between September 2003 and February 2021 including all patients who underwent a TR for a SCC involving the nasal vestibule. RESULTS 23 patients were included in the study. Tumours originated from the anterior septum (n = 12), vestibule (n = 8) or skin (n = 3). Six TRs (26.1%) were salvage procedures, after primary radiotherapy or partial rhinectomy. Seven patients had a concurrent neck dissection and 17 patients (73.9%) received adjuvant treatment (14 patients had radiotherapy and 3 had chemoradiotherapy). After a median follow-up of 32 months, six patients (26.1%) presented with tumour recurrence. Three patients (13%) had nodal-only recurrence. The estimated 5-year overall survival, disease-free survival and disease-specific survival were 67.5%, 66.3% and 80.7%, respectively. Positive excision margins were a predictive factor for tumour recurrence (p = 0.0401). CONCLUSION For SCCs involving the nasal vestibule that are not amenable to limited surgical resection, TR along with adjuvant radiotherapy provide good oncological outcomes and should be considered the main treatment option.

Abstract
OBJECTIVES Squamous cell carcinoma of nasal vestibule and pyramid is rare, thus classification, treatment protocol, and indications for elective neck treatment are still controversial. Nasal reconstruction is challenging, as well, and prosthesis is still used. STUDY DESIGN Retrospective cohort study. METHODS Retrospective review of patients surgically treated from 2010 to 2018 in a single Institution. Advanced tumors were further treated with adjuvant irradiation. Reconstruction strategy included grafts, locoregional and free flaps, and was customized on layers removed. RESULTS Forty-five patients were enrolled. The 5-year overall survival and disease-free survival were 81.9% ± 7.45% and 61.9% ± 9.09%, respectively. Wang's classification, site of origin, extent of surgery and margins status significantly correlated with prognosis and recurrence rate. Regional recurrences occurred in patients affected by advanced tumors who did not receive any form of elective neck treatment. CONCLUSION Multidisciplinary management and a proper reconstructive algorithm are recommended. Adjuvant irradiation and elective neck treatment should be advocated for advanced stage high-risk patients. LEVEL OF EVIDENCE 4. Laryngoscope, 131:E1198-E1208, 2021.

Eur Arch Otorhinolaryngol 2017; 274:3503-3512.

Abstract
The aim of this study was to analyze the role of Ki-67, p53, and the "aberrant p53 pattern" in squamous cell carcinomas of the nasal vestibule. Patients between 1995 and 2014 were included. Baseline characteristics and outcome were analyzed with respect to immunohistochemical staining of Ki-67 and p53. "Aberrant p53 pattern" was represented by a moderate or strong staining of at least 60% of the tumor cells or a complete absence of immunoreactivity. Forty-six patients were included of whom 31 (67.4%) were available for Ki-67 and 32 (69.9%) for p53 immunohistochemistry. The "aberrant pattern" of p53 was present in 50% of the patients. While immunoreactivity for both Ki-67 and p53 was not related to each other or outcome, the "aberrant p53 pattern" was associated with a worse disease-free survival (p = 0.014). The "aberrant p53 pattern" is a negative prognostic factor in squamous cell carcinoma of the nasal vestibule and might enable a patient-tailored treatment.
