Population-based Long-term Outcomes for Squamous Cell Carcinoma of the Nasal Cavity.

This study evaluates population-based outcomes of patients with squamous cell carcinoma (SCC) of the nasal cavity treated in British Columbia. A retrospective review of nasal cavity SCC treated from 1984 to 2014 was performed (n = 159). Locoregional recurrence (LRR) and overall survival (OS) were evaluated. The 3-year OS was 74.2% for radiation alone, 75.8% for surgery alone, and 78.4% for surgery and radiation ( P = 0.16). The 3-year LRR was 28.4% for radiation alone, 28.2% for surgery alone, and 22.6% for surgery and radiation ( P = 0.21). On multivariable analysis, surgery and postoperative radiation relative to surgery alone was associated with a lower risk of LRR (hazard ratio: 0.36, P = 0.03). Poor Eastern Cooperative Oncology Group status, node-positive, orbital invasion, smoking, and advanced age were associated with worse OS (all P <0.05). In this population-based analysis, multimodality treatment with surgery and adjuvant radiation were associated with improved locoregional control for SCC of the nasal cavity.

The role of elective neck dissection in T1 and T2 nasal cavity squamous cell carcinomas

PurposeTo evaluate the role of elective neck dissection (END) on oncological outcome in early-stage nasal cavity squamous cell carcinomas (SCCs).MethodsIn total, 87 patients with T1 (n = 59; 67.8%) and T2 (n = 28; 32.2%) SCCs were evaluated regarding performance of END, regional recurrences (RR) and its impact on cancer-specific survival (CSS). We further created a risk score based on T-classification, tumor subsite and grading to identify patients whom may benefit from END and calculated the corresponding numbers needed to treat (NNT) to prevent RR.ResultsNine (10.3%) patients experienced RR of whom 3 (5.1%) were T1 and 6 (21.4%) T2 tumors (p = 0.042). All RR originated from moderately or poorly differentiated (G2–G3) SCCs of the nasal septum or vestibule. END was done in 15 (17.2%) patients and none of those experienced RR (p = 0.121). Onset of RR represented the worst prognostic factor for CSS (HR 23.3; p = 0.007) with a 5y-CSS of 44.4% vs. 97.3% (p < 0.001). RR occurred in none of the patients with no or low risk scores compared to 31.6% (6/19) in patients with high-risk scores (p = 0.006). Accordingly, three high-risk patients would need to undergo END (NNT 2.63) to prevent RR compared to a NNT of 8 for the whole cohort.ConclusionsAlthough rare, occurrence of RR significantly deteriorates outcome in early stage nasal cavity SCCs, which could be effectively reduced by performance of END. The importance of END is currently underestimated and our proposed risk score helps identifying those patients who will benefit from END.

Nasal Cavity Squamous Cell Carcinoma: Factors Associated With Treatment Outcomes and Potential Organ Preservation.

Squamous cell carcinoma of the nasal cavity (NCSCC) is a rare, challenging malignancy. Surgical resection of this tumor can cause significant facial deformity, and indications for adjuvant or organ preservation therapies are not well-described. To examine the impact of treatment regimen on survival outcomes in NCSCC and to compare surgical to non-surgical based therapies. The National Cancer Database was queried for NCSCC from 2004 to 2014. Patient demographics, tumor characteristics, and treatment regimen were compared for the entire cohort. Multivariable Cox proportional hazards regression was performed for statistical analysis of treatment regimen and surgical margins on overall survival (OS) for early and late-stage disease. A total of 1883 NCSCC patients were identified. The OS for the cohort was 83 months, and median age at diagnosis was 65 years. NCSCC patients who underwent surgery followed by adjuvant radiation therapy (RT) had a better OS compared to definitive RT (HR: 0.58, P < .001). In early stage NCSCC (T1/T2, N0), there was no significant difference in OS between patients treated with surgery only or surgery with adjuvant RT compared to definitive RT. In advanced stage NCSCC, surgery with adjuvant RT had a better OS compared to definitive chemoradiation. Having positive margins was shown to predict a worse OS when compared to negative margins in surgical patients despite adjuvant RT or chemoradiation. NCSCC appears to be best treated with surgery followed by adjuvant RT in advanced-stage disease whereas in early-stage disease, surgery does not improve OS compared to definitive RT.

Squamous cell carcinoma of the nasal cavity: A descriptive analysis of cases from the head and neck 5000 study.

This paper aims to provide contemporary epidemiological data on squamous cell carcinoma (SCC) of the nasal cavity, which represents a rare type of head and neck cancer. A descriptive analysis of people with nasal cavity SCC treated with curative intent from the Head and Neck 5000 study; a multicentre clinical cohort study of people from the UK with head and neck cancer. People with tumours of the nasopharynx, paranasal sinuses and other sub-sites of the head and neck were excluded. Demographic data and treatment details are presented for all participants. The main outcomes were overall survival and survival according to categories of characteristics (eg, smoker vs non-smoker); these wereexplored using Kaplan-Meier plots. Thirty people with nasal cavity SCC were included in the study, of which most were male (67%) and current or ex-smokers (70%). The majority (70%) presented with early-stage (T1/2, N0) tumours. Cervical lymph node metastases at presentation were rare, occurring in only one person. Nine people died during the follow-up period (30%). Worse survival outcomes were seen in people with moderate or severe co-morbidities. This paper provides epidemiological data on nasal cavity SCC in the UK. Patterns of disease and survival outcomes are described, identifying high-risk groups. Further studies should explore whether primary treatment modality alters survival.

Risk of lymph node metastasis and recommendations for elective nodal treatment in squamous cell carcinoma of the nasal cavity and maxillary sinus: a SEER analysis

Background: Risk of nodal involvement in patients with squamous cell carcinomas (SCC) of the nasal cavity and maxillary sinus has not been well defined, especially by risk factors beyond local T-stage. Additional criteria defining patients at highest risk, as well as specific nodal levels at highest risk, has been limited in small retrospective series. We describe a population-based assessment of specific nodal involvement in this group.Material and methods: The Surveillance, Epidemiology and End Results (SEER) database from 2004 to 2010 identified 1283 eligible patients with SCC of the nasal cavity or maxillary sinus. Neck involvement and individual nodal level involvement at presentation were assessed, and comparison made with a contemporaneous cohort of patients with a borderline clinically significant risk of nodal involvement and recurrence.Results: Among 1283 patients, 182 (14.2%) had nodal involvement at presentation (4–27% by site and local extension). T-stage alone was associated with higher rates of nodal involvement in maxillary sinus SCC, while higher T-stage and size >2 cm were associated with higher rates of nodal involvement in nasal cavity SCC on multivariable analysis. Facial nodes and cervical nodes at levels 1 and 2 have the highest rates of involvement in T4a nasal cavity SCC, whereas nodal levels 1, 2, and/or 3 have the highest rates of involvement in T2 or higher maxillary sinus SCC when compared with a clinical reference standard.Conclusion: In this population-based study, there are high rates of initial nodal involvement when stratified by local extent determined by T-stage in nasal cavity SCC and maxillary sinus SCC, and independently by size in nasal cavity SCC. Involvement of the facial and nodal levels 1–3 varies depending on site and local extent of tumor involvement. These observations may help guide treatment decision making in the inclusion of and extent of elective nodal treatment fields.

Definitive and adjuvant radiotherapy for sinonasal squamous cell carcinomas: a single institutional experience.

BackgroundThe aim of this study was to evaluate the disease outcomes of patients treated with definitive and adjuvant radiotherapy for squamous cell carcinomas of the nasal cavity and paranasal sinuses in a single institution.MethodsBetween 2007–2012 patients were retrospectively identified from electronic databases who had undergone surgery and adjuvant radiotherapy or definitive radiotherapy for sinonasal squamous cell carcinomas with curative intent.ResultsFourty three patients with sinonasal squamous cell carcinoma were identified (22 nasal cavity, 21 paranasal sinuses). 31/43 (72 %) had T3 or T4 disease; nodal stage was N0 in 38, N1 in 4, Na/b in 0 and N2c in 1 patient. Median age was 67 years (range 41–86). 18 (42 %) received definitive and 25 (58 %) adjuvant radiotherapy. Radiotherapy was delivered using either conventional radiotherapy (n = 39) or intensity modulated radiotherapy (n = 4). Elective neck radiotherapy was delivered to two patients. Chemotherapy was delivered to 6/43 (14 %) of patients. Two-year local control, regional control, distant metastases free survival, progression free survival, cause specific survival and overall survival were 81 %, 90 %, 95 %, 71 %, 84 % and 80 % respectively. There was no significant difference in outcome comparing patients who underwent surgery and adjuvant radiotherapy with patients receiving definitive radiotherapy (2 year locoregional disease free survival 75 % and 70 % respectively, p = 0.98). Pooly differentiated tumours were significantly associated with inferior disease outcomes. Local, regional, combined local and regional, and distant failure occurred in 7 (16 %), 3 (7 %), 1 (2 %) and 2 (5 %) of patients; all 3 regional recurrences were in patients with nasal cavity squamous cell carcinomas who had not undergone elective neck treatment.ConclusionsDefinitive or adjuvant radiotherapy provides an effective treatment for sinonasal malignancies. The main pattern of failure remains local, suggesting the need for investigation of intensified local therapy. Whilst remaining uncommon, the cases of regional failure mean that the merits of elective lymph node treatment should be considered on an individual basis.

Basaloid Squamous Cell Carcinoma of the Nasal Septum Presenting as a Primary Cutaneous Lesion

Basaloid squamous cell carcinoma is a rare aggressive variant of squamous cell carcinoma, with a predilection for the head and neck region. There are only two case reports in the literature documenting a nasal cavity squamous cell carcinoma presenting as a primary cutaneous lesion. We report a rare case of nasal cavity basaloid squamous cell carcinoma presenting initially as a nasal bridge mass. Two initial biopsies revealed features consistent with basal cell carcinoma and basosquamous cell carcinoma, respectively. Final surgical pathology showed extensive invasive squamous cell carcinoma with basaloid differentiation arising from the nasal septal mucosa with extension to the overlying skin. The clinicopathologic features were interpreted as basaloid squamous cell carcinoma. We discuss the difficulties in pathologic diagnosis of this condition given its varied phenotypical expression. As well, this case emphasizes the necessity for diagnostic vigilance when assessing a primary cutaneous lesion as it may be a rare presentation of an underlying malignancy extending to the skin.

Expression and significance of matrix metalloproteinase and tissue inhibitor of metalloproteinase in nasal cavity squamous cell carcinoma.

To study the expression and significance of matrix metalloproteinase (MMP) 2, MMP-9, tissue inhibitor of metalloproteinase (TIMP)1 and TIMP-2 in nasal cavity squamous cell carcinoma and their signification. Fifty cases of epithelial carcinoma tissue and 50 cases of normal nasal tissue were detected for MMP-2, MMP-9, TIMP-1, TIMP-2 by immunohistochemistry technique (S-P), and their relationship between the expression of MMP-2, MMP-9, TIMP-1, TIMP-2 and some clinical symptoms were analyzed. The SPSS 12.0 software was used to analyze the data. The positive ratio of expression of MMP-2 in 50 cases of epithelial carcinoma was 52.0% (26/50), which was significantly higher (χ(2) = 6.00, P < 0. 05) than those [28.0% (14/50)] in the normal nasal tissue. The positive ratio of expression of MMP-9 in 50 cases of epithelial carcinoma was 58.0% (29/50), which was significantly higher (χ(2) = 12.8, P < 0.05) than those [10.0% (5/50)] in the normal nasal tissue. The positive ratio of expression of TIMP-1 in two groups was 74.0% (37/50), 56.0% (28/50) respectively. There was no difference between two groups (χ(2) = 0.51, P > 0.05). The positive ratio of expression of TIMP-2 in two groups was 26.0% (13/50), 20% (10/50) respectively. There was no difference between two groups (χ(2) = 3.35, P > 0.05). There was a close relationship between pathogenesis and development of nasal epithelial carcinoma and the expression of MMP-2, MMP-9 in the epithelial carcinoma tissues. Both MMP and TIMP, especially the unbalance of MMP and TIMP, have prognostic value in nasal cavity squamous cell carcinoma.

Spontaneous squamous cell carcinomas in 13 baboons, a first report in a spider monkey, and a review of the non‐human primate literature

Squamous cell carcinoma (SCC) is a neoplastic proliferation of epithelial cells undergoing squamous differentiation and represents a diagnostic challenge in non-human primates (NHP), especially in baboons with perineal SCC. Fourteen SCC (13 baboons, 1 spider monkey) were identified over a 20-year period. A literature search identified 86 additional published cases of spontaneous NHP SCC. Squamous cell carcinoma was most commonly reported in macaques, baboons, marmosets, and squirrel monkeys. Metastasis occurred in 23%, of NHP. The most frequently reported primary locations were the oral cavity, integument, esophagus, and cervix-uterus. Perineal SCC occurred mainly in baboons. All reported SCC in marmosets occurred in the head. Nasal cavity SCC was only reported in male marmosets. All reported pulmonary SCC occurred in males, mostly in tree shrews. Squamous cell carcinoma is a common neoplasm in NHP and exhibits species differences. NHPs may provide a useful SCC animal model.

Cerebral Radionecrosis with Cystic Degeneration Following Radiotherapy for Nasal Cavity Squamous Cell Carcinoma: A Case Report

A 31-year-old man with nasal cavity squamous cell carcinoma was treated in our hospital with two courses of radiotherapy (120 Gy total dose) followed by surgical tumor resection. Three years after the last irradiation, he developed seizures as well as changes in behavior and consciousness. Medical therapy with diphenylhydantoin (Dilantin) terminated the seizures. Dysphagia, unsteady gait, and right-side limb weakness developed 37 months after the onset of seizures. Magnetic resonance imaging showed a large, cystic mass in the left temporal lobe with left to right midline shift. Following craniotomy with decompression of the cystic mass, the patient improved clinically. No malignant cells were found in the specimen. No further progression of neurologic symptoms was noted after a 1-year follow-up. Cerebral radionecrosis is an uncommon late complication of radiotherapy and needs to be differentiated from tumor recurrence or metastasis if the irradiation field covers the cerebral region in patients with head and neck malignancies.

Squamous cell carcinoma of the nasal vestibule and anterior nasal passages

Purpose: This retrospective review of nasal vestibule and anterior nasal cavity squamous cell carcinomas correlates clinical presentation, methods of treatment, and histologic differentiation with outcome. Patlents and Materlals: Epidemiologic data, patient history, and physical findings for 25 cases are presented. Cigarette usage was prevalent in this group, as it is in most series of patients with epithelial tumors of head and neck locations. Treatment was surgery alone (n = 10), irradiation (n = 4), or combined therapy (n = 11). Results: Combined surgery and postoperative irradiation yielded better recurrence-free survival than either treatment used alone. Concluslons: Although the series studied was small and the selection criteria for treatment were not uniform, this retrospective study supports wide surgical resection combined with postoperative irradiation as the preferred treatment of squamous cell carcinoma of the nasal vestibule with extension to adjacent areas. However, tratment should be individualized to provide the greatest chance for cure while preserving nasal form and function as far as is possible in each patient.

Risk assessment of laboratory rats and mice chronically exposed to formaldehyde vapors.

Experimental data from the Chemical Industry Institute of Toxicology (CIIT) are used to estimate the risk of squamous cell carcinoma of the nasal cavity in Fischer 344 (F344) rats over a range of ambient air concentrations of formaldehyde that includes current exposure guidelines for the workplace and home. These values are presented as a best estimate envelope obtained from five mathematical dose-response formulation. The response of Sprague-Dawley (SD) rats dosed at 15 ppm in a separate study at New York University is consistent with the predicted lifetime response for F344 rats at a slightly lower concentration (13-14 ppm). A dose-related mortality effect beyond what is attributable to the occurrence of nasal carcinomas is found in F344 rats at all CIIT exposure levels (2, 6, and 15 ppm). There is no evidence of a mortality effect in B6C3F1 mice of the CIIT study, and data for SD rats of the NYU experiment are inconclusive. In the CIIT study, rats exposed to 15 ppm exhibited a high incidence of nasal cavity squamous cell carcinomas and polypoid adenomas. Polypoid adenomas were also observed with increased incidences at 2 ppm and 6 ppm. Statistical comparisons with matched controls, and the low historical rate of spontaneous occurrence both suggest that polypoid adenomas may be a risk to F344 rats at exposure levels below the current Occupational Safety and Health Administration (OSHA) standard of 3 ppm. Squamous cell carcinomas were observed in two mice exposed to 15 ppm. This finding may be biologically significant since this tumor is rare and has not been previously reported in 4932 untreated B6C3F1 mice from recent National Toxicology Program (NTP) feeding studies.
