INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 20:387. [PMID: 36612710 PMCID: PMC9819044 DOI: 10.3390/ijerph20010387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 12/13/2022] [Accepted: 12/22/2022] [Indexed: 06/17/2023]
Abstract
The aim of the current study was to investigate the relationship between nasopharyngeal carcinoma (NPC) and dry eye disease (DED) using the National Health Insurance Research Database (NHIRD) of Taiwan. A retrospective cohort study was conducted, and patients with an NPC diagnosis were included. Next, one NPC patient was matched to four non-NPC participants via demographic data and systemic comorbidities. In total, 4184 and 16,736 participants were enrolled in the NPC and non-NPC groups, respectively. The primary outcome was the development of DED one year after the diagnosis of NPC. Cox proportional hazard regression was applied to estimate the adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) of DED. In this study, 717 and 2225 DED cases were found in the NPC and non-NPC groups, respectively, and the NPC group showed a significantly higher incidence of DED development compared to the non-NPC group (aHR: 1.45, 95% CI: 1.33−1.58, p < 0.0001) in the multivariable analysis. The other covariates that were positively correlated with DED development included age over 40 years, an education level higher than senior high school, hypertension, DM, allergic pulmonary diseases, allergic otolaryngologic diseases, and allergic dermatological diseases (all p < 0.05). In conclusion, the presence of NPC is an independent risk factor for subsequent DED.

The Nasopharyngeal Carcinoma and Its Effect on the Infectious Eye Disease: A Nationwide Cohort Study. Cancers (Basel) 2022; 14:cancers14235745. [PMID: 36497227 PMCID: PMC9736111 DOI: 10.3390/cancers14235745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/09/2022] [Accepted: 11/21/2022] [Indexed: 11/24/2022] Open
Abstract
The purpose of this study is to investigate the potential correlation between nasopharyngeal carcinoma (NPC) and both infectious keratitis and orbital cellulitis. The retrospective cohort study used the National Health Insurance Research Database (NHIRD) as a data source. A total number of 4184 patients with NPC diagnosis were selected and matched to 16,736 non-NPC patients via the propensity-score matching (PSM). The main outcomes are the development of infectious keratitis and orbital cellulitis according to diagnostic codes and related medications. The Cox proportional hazard regression was adopted to estimate the adjusted hazard ratio (aHR) and 95% confidence interval (CI) of outcomes between the two groups. A total of 35 and 19 episodes of orbital cellulitis occurred in the NPC and non-NPC groups and the aHR was significantly higher in the NPC group (aHR: 1.34, 95% CI: 1.23−1.46, p = 0.0024). There were 2185 and 659 events of infectious keratitis in the NPC and non-NPC groups, and the NPC group revealed a significantly higher aHR than non-NPC group (aHR: 1.34, 95% CI: 1.23−1.46, p < 0.0001). Besides, the cumulative probability of infectious keratitis was significantly higher in the NPC group than the non-NPC group (p < 0.0001). The other risk factors of infectious keratitis include age from 20 to 30 years old, allergic respiratory diseases, allergic dermatological diseases, and external eye diseases (all p < 0.0001). In subgroup analyses, both the incidences of infectious keratitis (aHR: 1.33, 95% CI: 1.21−1.47) and orbital cellulitis (aHR: 2.36, 95% CI: 1.27−4.39) were significantly higher than the non-NPC group. The incidence of infectious keratitis was significantly higher in NPC patients without radiotherapy (aHR: 1.40, 95% CI: 1.26−1.55) compared to non-NPC population, while the rate of orbital cellulitis was similar between the NPC patients without radiotherapy (aHR: 0.76, 95% CI: 0.27−2.14) and non-NPC population. In conclusion, the existence of NPC associates with higher incidence of infectious keratitis which increases with NPC period, and the radiotherapy may be account for the higher rate of orbital cellulitis in NPC population.

Abstract
Nasopharyngeal carcinoma is a prevalent head and neck cancer, especially in Southeast Asia. Although its potential for distant metastasis is well established, metastasis to the breast has seldom been reported. To the best of our knowledge, this is the fourth report of a case of nasopharyngeal carcinoma metastasizing to bilateral breasts. A 35-year-old patient presented with left nasal obstruction, epistaxis, and a palpable mass in her left breast, without any cervical or axillary lymph nodal enlargement. Radiological examination with contrast-enhanced computed tomography scan and magnetic resonance and imaging of breast revealed the presence of enhancing mass lesions in bilateral breasts. Histopathology of the nasal mass was suggestive of undifferentiated nasopharyngeal carcinoma. Breast fine needle aspiration revealed an abundance of metastatic squamous cells. Immunohistochemistry examination was positive for chromogranin A, synaptophysin, and cluster of differentiation-56, confirming the diagnosis of a primary nasopharyngeal malignancy metastasizing to bilateral breasts. Differentiation between metastatic disease and a coexisting second primary is imperative for planning appropriate treatment and defining the further outcomes.

Abstract
Nasopharyngeal carcinoma is very rarely associated with bilateral vision loss, and only in advanced disease. We report a case of bilateral severe compressive optic neuropathy as a first presentation from massive nasopharyngeal carcinoma with poor visual outcome despite corticosteroid, chemotherapy and radiotherapy. Red flag symptoms and signs of mass lesions in the posterior nasal space should be investigated and treated promptly to prevent devastating visual and prognostic consequences.

Abstract
Introduction: Nasopharyngeal carcinoma (NPC) is a tumor arising from the epithelial cells of the nasopharynx. NPC can spread and invade the base of skull, nasal cavity, paranasal sinuses, pterygopalatine fossa, and apex of the orbit. However, the involvement of the optic nerve in NPC is rare. The purpose of this case report is to report the efficacy of corticosteroid therapy in optic neuropathy secondary to NPC. Clinical case: A 56-year-old Chinese woman, an active smoker, presented with a hearing deficit, persistent tinnitus and nasal congestion. Examination and investigations revealed the presence of a mass in the nasopharynx. Tissue biopsy revealed nasopharyngeal carcinoma. However, the Epstein-Barr virus was not tested. She was counseled for chemotherapy, but refused and was subsequently lost to follow up. She presented one year later with right eye ptosis associated with progressive worsening of diplopia and blurring of vision. Examination revealed multiple (second, third, fourth and sixth) cranial nerve involvement. Systemic examination and investigations revealed cervical lymphadenopathy and liver metastasis. Repeated imaging showed that the mass had invaded the base of the skull, cavernous sinus and orbital apices. Pulse dosing of corticosteroid therapy was commenced, resulting in dramatic improvement of vision. Conclusion: Optic neuropathy may be the presenting sign of NPC. Corticosteroid therapy can offer immediate visual improvement.

Abstract
Purpose Neuro-ophthalmic manifestations may be the first and sole presenting feature of a nasopharyngeal carcinoma. Peri-neural spread is an emerging phenomenon that explains the distant spread of tumour cells well beyond the local extent of invasion. This under recognized route of tumour spread often results in delayed diagnosis and reduced life expectancy. The authors report a case of an isolated third nerve palsy as the only initial manifestation of nasopharyngeal carcinoma and emphasize the need for a high index of suspicion. Observation The patient presented with left painful pupil involving complete third nerve palsy. Contrast enhanced imaging was initially deferred due to renal impairment. Plain MRI with MRA brain was normal. Hematology was suggestive of giant cell arteritis which is a rare but well documented cause of painful nerve palsies in the elderly. Unresponsiveness to steroids prompted contrast imaging with a reduced gadolinium dosing and hemodialysis backup which finally revealed a nasopharyngeal carcinoma. Conclusion and importance This report is the journey of a third nerve palsy from a clinical diagnosis of an aneurysm (pupil involving palsy) to a probable diagnosis of giant cell arteritis (based on hematology) and to a final diagnosis of nasopharyngeal carcinoma (based on contrast imaging and immunohistochemistry)Nasopharyngeal carcinoma can be successfully cured if detected early. This report highlights the various manifestations of nasopharyngeal carcinoma and challenges faced in diagnosing this elusive tumor.

Abstract
For years, the conventional imaging modalities are generally used in dental practice routine. They provide precious information about dentomaxillofacial region; they also have some limitations such as superimpositions, magnifications, distortions, and low-image quality. Because of these limitations, some pathologies, calcifications, and anatomical variations may be missed. Any findings on a radiographic image which are not related to the research areas of interest could be a description of “incidental findings.” Calcifications are one of these incidental findings. They are asymptomatic and also common in TMJ images. Although most of the calcifications require no treatment, correct identification will reduce further diagnostic assessments. Incidental findings on TMJ images were rare, while examining images for temporomandibular disorders and associated issues, it is important not only to examine the TMJ structures but also to look at the nearby anatomical features to check for evidence of incidental findings pathologies that may have mimicked signs and symptoms of TMJ disorders.

Abstract
This article desribes the ophthalmic involvement in patients with nasopharyngeal carcinoma (NPC) pre- and post-treatment. We retrospectively reviewed data for 354 consecutive patients diagnosed with or treated for NPC at a single tertiary centre between April 2007 and July 2015. We identified 27 (7.6%) patients with ophthalmic involvement due to NPC or its treatment. Symptomatic orbital invasion by tumor occurred in 13 of 27 patients (48.1%). The mean age of diagnosis in these patients was 54 years, and 8 (61.5%) had no prior diagnosis of NPC. Ocular signs, but no orbital invasion, was present in 8 patients (29.6%). Incidental orbital involvement was detected on imaging in 2 patients (7.4%). Radiotherapy-related ocular complications affected 4 patients (14.8%). Ophthalmic symptoms from orbital invasion can be the initial presentation of NPC. This disease tends to affect a younger group of patients and early recognition is important to minimize morbidity and mortality.

Abstract
Background The prognostic values of staging parameters require continual re-assessment amid changes in diagnostic and therapeutic methods. This study aimed to identify the prognostic factors and failure patterns of non-metastatic nasopharyngeal carcinoma (NPC) in the intensity-modulated radiotherapy (IMRT) era. Methods We reviewed the data from 749 patients with newly diagnosed, biopsy-proven, non-metastatic NPC in our cancer center (South China, an NPC endemic area) between January 2003 and December 2007. All patients underwent magnetic resonance imaging (MRI) before receiving IMRT. The actuarial survival rates were estimated using the Kaplan–Meier method, and survival curves were compared using the log-rank test. Multivariate analyses with the Cox proportional hazards model were used to test for the independent prognostic factors by backward eliminating insignificant explanatory variables. Results The 5-year occurrence rates of local failure, regional failure, locoregional failure, and distant failure were 5.4, 3.0, 7.4, and 17.4%, respectively. The 5-year survival rates were as follows: local relapse-free survival, 94.6%; nodal relapse-free survival, 97.0%; distant metastasis-free survival, 82.6%; disease-free survival, 75.1%; and overall survival, 82.0%. Multivariate Cox regression analysis revealed that orbit involvement was the only significant prognostic factor for local failure (P = 0.011). Parapharyngeal tumor extension, retropharyngeal lymph node involvement, and the laterality, longest diameter, and Ho’s location of the cervical lymph nodes were significant prognostic factors for both distant failure and disease failure (all P < 0.05). Intracranial extension had significant prognostic value for distant failure (P = 0.040). Conclusions The key failure pattern for NPC was distant metastasis in the IMRT era. With changes in diagnostic and therapeutic technologies as well as treatment modalities, the significant prognostic parameters for local control have also been altered substantially.

Abstract
Extraocular eye movement disorders are relatively common and may be a significant source of discomfort and morbidity for patients. The presence of restricted eye movement can be detected clinically with quick, easily performed, noninvasive maneuvers that assess medial, lateral, upward, and downward gaze. However, detecting the presence of ocular dysmotility may not be sufficient to pinpoint the exact cause of eye restriction. Imaging plays an important role in excluding, in some cases, and detecting, in others, a specific cause responsible for the clinical presentation. However, the radiologist should be aware that the imaging findings in many of these conditions when taken in isolation from the clinical history and symptoms are often nonspecific. Normal eye movements are directly controlled by the ocular motor cranial nerves (CN III, IV, and VI) in coordination with indirect input or sensory stimuli derived from other cranial nerves. Specific causes of ocular dysmotility can be localized to the cranial nerve nuclei in the brainstem, the cranial nerve pathways in the peripheral nervous system, and the extraocular muscles in the orbit, with disease at any of these sites manifesting clinically as an eye movement disorder. A thorough understanding of central nervous system anatomy, cranial nerve pathways, and orbital anatomy, as well as familiarity with patterns of eye movement restriction, are necessary for accurate detection of radiologic abnormalities that support a diagnostic source of the suspected extraocular movement disorder. ©RSNA, 2016.

Abstract
Clinical target volume (CTV) delineation is crucial for tumor control and normal tissue protection. This study aimed to define the locoregional extension patterns of nasopharyngeal carcinoma (NPC) and to improve CTV delineation. Magnetic resonance imaging scans of 2366 newly diagnosed NPC patients were reviewed. According to incidence rates of tumor invasion, the anatomic sites surrounding the nasopharynx were classified into high-risk (>30%), medium-risk (5%–30%), and low-risk (<5%) groups. The lymph node (LN) level was determined according to the Radiation Therapy Oncology Group guidelines, which were further categorized into the upper neck (retropharyngeal region and level II), middle neck (levels III and Va), and lower neck (levels IV and Vb and the supraclavicular fossa). The high-risk anatomic sites were adjacent to the nasopharynx, whereas those at medium- or low-risk were separated from the nasopharynx. If the high-risk anatomic sites were involved, the rates of tumor invasion into the adjacent medium-risk sites increased; if not, the rates were significantly lower (P < 0.01). Among the 1920 (81.1%) patients with positive LN, the incidence rates of LN metastasis in the upper, middle, and lower neck were 99.6%, 30.2%, and 7.2%, respectively, and skip metastasis happened in only 1.2% of patients. In the 929 patients who had unilateral upper neck involvement, the rates of contralateral middle neck and lower neck involvement were 1.8% and 0.4%, respectively. Thus, local disease spreads stepwise from proximal sites to distal sites, and LN metastasis spreads from the upper neck to the lower neck. Individualized CTV delineation for NPC may be feasible.

Abstract
PURPOSE To report a unique approach to the orbital apex through the contralateral orbit. METHODS A 65-year-old male presented with right compressive optic neuropathy due to nasopharyngeal carcinoma spread. Clinical evaluation and imaging showed a right orbital apex mass. Surgery included apical orbital tumor debulking, and orbital decompression performed via the contralateral exenterated side. Postoperatively, symptoms were relieved. CONCLUSIONS Orbitotomy via the contralateral exenterated orbit should be considered as a surgical option in these unique patients requiring direct access to the orbital apex.
