Abstract
Background Orbital tumors, arising within the bony orbit and its contents, present diverse challenges due to their varied origins and complex anatomical context. These tumors, classified as primary, secondary, or metastatic, are further subdivided into intraconal and extraconal based on their relationship with the muscle cone. This classification significantly influences surgical approach and management. This study highlights surgical experiences with orbital tumors, underscoring the importance of tailored surgical approaches based on the lesion's site and its proximity to the optic nerve. Methods This retrospective study at the National Institute of Cancer's Head and Neck Department (2005-2014) analyzed 29 patients with orbital tumors treated with surgery, radiotherapy, chemotherapy, or combinations of them. Patient demographics, tumor characteristics, and treatment responses were evaluated using computed tomography (CT), magnetic resonance imaging, and positron emission tomography-CT imaging. Malignant tumors often required orbital exenteration and reconstruction, highlighting the study's commitment to advancing orbital tumor treatment. Results 29 patients (18 females and 11 males, age 18-88 years, mean 53.5 years) with orbital tumors exhibited symptoms such as decreased vision and exophthalmos. Tumors included primary lesions like choroidal melanoma and secondary types like epidermoid carcinoma. Treatments varied, involving a multidisciplinary team for surgical approaches like exenteration, with follow-up from 1 to 9 years. Radiotherapy and chemotherapy were used for specific cases. Conclusion Our study underscores the need for a multidisciplinary approach in treating orbital tumors, involving various surgical specialists and advanced technologies like neuronavigation for tailored treatment. The integration of surgery with radiotherapy and chemotherapy highlights the effectiveness of multidimensional treatment strategies.

Clinico-epidemiological analysis of 1000 cases of orbital tumors. Jpn J Ophthalmol 2021; 65:704-723. [PMID: 34313901 DOI: 10.1007/s10384-021-00857-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Accepted: 06/17/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE To clarify the incidence, demography and clinical features of orbital tumors diagnosed in a single institute in Japan. STUDY DESIGN Retrospective, observational case series. METHODS Patients with primary orbital tumors including tumor-like lesions diagnosed clinically or histopathologically at Tokyo Medical University Hospital between 1995 and 2019 were analyzed. Incidence of all orbital tumors, demographic profile and clinical features of major benign and malignant tumors were reviewed retrospectively. RESULTS Totally 1000 cases of primary orbital tumor were diagnosed clinically or histopathologically during the study period. Benign tumors accounted for 72% and malignant tumors 28%. 55% of benign tumors and 99% of malignant tumors were proven histopathologically. The most common benign orbital tumor was idiopathic orbital inflammation (27%), followed by IgG4-related ophthalmic disease (17%), cavernous venous malformation (13%) and pleomorphic adenoma (9%). The most common malignant tumor was lymphoma (70%), followed by adenoid cystic carcinoma (7%) and solitary fibrous tumor (5%). CONCLUSIONS Epidemiology of orbital tumors has changed by the improvement of imaging techniques, establishment of novel clinical and histopathological criteria, and changes in population age structure associated with the aging society. Currently, lymphoproliferative diseases including lymphoma and IgG4-related ophthalmic diseases form the major orbital tumors in Japan.

Population-based survival of pediatric rhabdomyosarcoma of the head and neck over four decades. Int J Pediatr Otorhinolaryngol 2021; 142:110599. [PMID: 33422992 DOI: 10.1016/j.ijporl.2020.110599] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 12/04/2020] [Accepted: 12/26/2020] [Indexed: 11/24/2022]
Abstract
OBJECTIVES Clinical trials have reported increases in the survival of pediatric rhabdomyosarcoma (RMS) from 25% in 1970 to 73% in 2001. The purpose of this study was to examine whether survival of pediatric patients with RMS of the head and neck improved at the US population level. METHODS A population-based cohort of patients with rhabdomyosarcoma of the head and neck aged 0-19 years in the Surveillance, Epidemiology, and End Results (SEER) registry from 1973 to 2013 was queried. The cumulative incidence competing risks (CICR) method was used to estimate risk and survival trends. RESULTS 718 cases were identified for analysis. Survival rates at 1-, 5-, and 10-years after diagnosis were 91.2%, 73.2%, and 69.4% respectively. Survival rates at 1 year after diagnosis increased from 82.6% to 93.1% during the study period. In the subdistributional hazard analysis, there was a significantly improved disease-specific risk of death in the first year after diagnosis. Overall risk of death did not improve significantly. Favorable prognostic factors included age <10 years at diagnosis, smaller tumor size, absence of distant metastasis, localized tumors, earlier stage at presentation, grossly complete surgical resection, and embryonal or botryoid histology. CONCLUSIONS Disease-specific survival in the first year following diagnosis improved, but the change in overall survival at the population level was not statistically significant. These findings should be interpreted in light of the inclusion of patients with distant metastasis at diagnosis, who have poor prognoses, together with the limited statistical power afforded in studies of rare diseases.

Second primary malignancies of eye and ocular adnexa after a first primary elsewhere in the body. Graefes Arch Clin Exp Ophthalmol 2020; 259:515-526. [PMID: 32870371 PMCID: PMC7843581 DOI: 10.1007/s00417-020-04896-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Revised: 08/09/2020] [Accepted: 08/12/2020] [Indexed: 12/26/2022] Open
Abstract
Purpose The eye and its adnexal structures can give rise to first or consecutive primary malignancies or to encounter metastasis. Our aim was to define the characteristics of the second primary neoplasms affecting the eye and its adnexa and find the risk modifying factors for them after malignancies elsewhere in the body. Methods We have queried the Surveillance, Epidemiology and End-Results “SEER”-9 program of the National Cancer Institute for the malignancies of the eye and its adnexa that occurred between 1973 and 2015. The malignancies were ordered chronologically according to their incidence: first or second primary malignancies. The tumors were classified according to ICD-O-3 classification. Standardized incidence ratios (SIR) and survival probabilities were calculated for subgroups. Results Among 3,578,950 cancer patients, 1203 experienced a second malignancies of the eye and its adnexa. The first malignancy was diagnosed between 50 and 69 years of age in 58.94% of them. The eyelid showed 280 events, while 50 in lacrimal gland, 181 in the orbit, 21 in the overlapping lesions, 15 in optic nerve, 148 in the conjunctiva, 9 in the cornea, 6 in the Retina, 379 in the choroid, and 93 in the ciliary body. The SIR of a second malignancy after a prior non-Hodgkin lymphoma was 2.42, and in case of previous skin carcinomas it was 3.02, melanoma of skin, and 2.13 and 1.58 in oral cavity/pharynx malignancies. The second ocular and adnexal neoplasms increased steadily over the 5-year periods on contrary to first primary neoplasms. The survival of patients affected with first ocular and adnexal neoplasms was significantly higher than those with second ocular and adnexal neoplasms. On the other side, second primary ocular and adnexal tumors showed a better survival than second primary malignancies elsewhere. Conclusions The epidemiological differences between first and second ocular and adnexal primaries suggest different underlying mechanisms. Careful ocular examination should be integrated in the long-term follow-up plan of cancer patients. Special attention should be given to patients with non-Hodgkin’s lymphoma and melanoma as first primary.![]() Electronic supplementary material The online version of this article (10.1007/s00417-020-04896-1) contains supplementary material, which is available to authorized users.

Abstract
BACKGROUND The treatment of tumors increasingly takes place in specialised interdisciplinary centres. Therapeutic decisions are usually made at case conferences. Ophthalmologists, oromaximillofacial surgeons, ENT physicians, neurosurgeons, as well as pediatricians, radiotherapists and radiologists are all involved in the treatment of orbital diseases. The aim of this article is to present the concept of a multidisciplinary case conference for orbital diseases and to analyse case numbers, indications, and the influence on the patient's therapy. METHODS We analysed an anonymized data set of patients who presented in the case conference of the University Hospital Freiburg from 2008 to 2018 with regard to clinical diagnosis, histological diagnoses, number of surgical interventions, and number of interdisciplinary therapy decisions. RESULTS From 2008 to 2018, 545 patients were presented in a weekly conference. Of these, 453 were available for anonymous evaluation. The median age was 56 years (quartiles 41; 69). The most frequent indication was an orbital tumour of unclear malignancy (n = 52; 11%). Further indications included Grave's orbitopathy (n = 39; 9%), orbital pseudotumour (n = 36; 8%), cranial nerve palsy (n = 22; 5%), and orbital lymphoma (n = 22; 5%). The most frequent histological diagnoses were B-cell lymphoma (n = 10; 2%), venous malformation (cavernoma, n = 8; 2%), marginal zone lymphoma (n = 8; 2%), and squamous cell carcinoma (n = 6; 1%). An interdisciplinary therapeutic approach was defined for 174 patients. CONCLUSION A high demand for the interdisciplinary case conference was demonstrated. The high rate of primary or secondary interdisciplinary decisions indicates the value of such a conference. Hence, the patient is spared multiple examinations in the individual specialist areas and quick and effective therapy decisions can be achieved.

Abstract
PURPOSE We performed an epidemiological study of orbital lymphoma in the United States to determine how histological subtypes confer differing prognosis, and understand other factors associated with survival. METHODS All patients in the Surveillance, Epidemiology and End Results database diagnosed with a histologically confirmed orbital lymphoma between 1973 and 2014 were included. Exclusion criteria included diagnosis at autopsy and the presence of other malignancies. Measures included patient demographic information, histological subtype and treatment modalities. Outcomes included overall and disease specific survival. RESULTS Of the 1504 cases identified, 702 were male (46.7%, mean age: 64.4 years, standard deviation [SD]: 15.3) and 802 were female (53.3%, mean age: 67.5 years, SD: 14.3). Mucosal associated lymphoid tissue (MALT) (49.5%) and diffuse large B cell lymphoma (DLBCL) (19.5%) were the two most common histologic subtypes. MALT lymphoma conferred the best prognosis (10-year cancer specific survival [CSS] 90.2%, 95% Confidence Interval [CI] 87.4% - 93.1%) and DLBCL conferred the worst prognosis (10-year CSS 68.6%, 95% CI 62.5% - 75.3%) (p < .001, log-rank test). Older age (Hazard Ratio [HR]: 3.71, 95% Confidence Interval [CI]: 2.94-4.66, p < .001), male sex (HR: 1.22, 95% CI: 1.039-1.441, p = .015), no radiation (HR: 1.72, 95% CI: 1.46-2.02, p < .001) and DLBCL histology were significant predictors of worse overall survival. CONCLUSIONS DLBCL histology confers the worst outcomes whereas MALT lymphoma confers the best outcome in orbital lymphoma. Age, gender, and radiation treatment also influence survival. These epidemiological results can be used clinically to communicate outcomes on the basis of patient characteristics and disease histology.

Abstract
Objectives Cranioorbital lesions present a great challenge for neurosurgeons and ophthalmologists. There is no consensus on the choice of surgical approach. The aims of this study were to investigate 49 cases of cranioorbital lesions and evaluate surgical approaches and outcomes. Patients and Methods A retrospective study was done on 49 patients (51 operations) from 2009 to 2018. Information about the lesion was used to decide whether the supraorbital eyebrow approach (SEA) or pterional approach (PA) was performed. Results Twenty-eight patients had surgical resection using SEA, 21 patients received PA, each group included one case of recurrence, who underwent reoperation via the same approach. SEA provided better cosmetic satisfaction, and a shorter incision than PA ( p < 0.05). There was no significant difference in total resection rates, visual outcomes, recovery of ptosis, and other new surgical-related complications between SEA group and PA group ( p > 0.05). Forty-nine cases of proptosis (94.1%, 49/51) were improved. Thirty-three patients (33/37, 89.2%) who underwent follow-up for longer than 12 weeks had a modified Rankin Scale (mRS) score ≤ 3. Conclusion Surgery is the preferred treatment for cranioorbital lesions, but total resection is difficult. SEA may be a more minimally invasive option for some more limited lesions superior to optic nerve. PA may be more reasonable for the lesion with obvious hyperostosis and more extensive lesions.

Abstract
Orbital lymphomas constitute 50-60% of ocular adnexal lymphomas. A total of 2211 cases of orbital lymphoma with a known subtype have been reported in the last 24 years (1994-2017). The vast majority of orbital lymphomas are of B-cell origin (97%), of which extranodal marginal zone B-cell lymphoma (EMZL) (59%) is the most common subtype, followed by diffuse large B-cell lymphoma (23%), follicular lymphoma (9%), and mantle cell lymphoma (5%). Orbital lymphoma is primarily a disease of the elderly. Gender distribution varies according to lymphoma subtype. However, extranodal marginal zone B-cell lymphoma (53%) and follicular lymphoma (75%) show a female predominance, whereas diffuse large B-cell lymphoma shows an even gender distribution. Mantle cell lymphoma has a striking male predominance of 80%. The histopathological subtype and the clinical stage of the disease are the best indicators of prognosis and patient outcome. Low-grade lymphomas such as extranodal marginal zone B-cell lymphoma and FL have a good prognosis, whereas high-grade lymphomas (diffuse large B-cell lymphoma and mantle cell lymphoma) are associated with a poor prognosis. When managing solitary low-grade lymphomas, radiotherapy is the treatment of choice. Chemotherapy, with or without radiotherapy, should be chosen for disseminated and high-grade lymphomas.

Abstract
OBJECTIVE To assess clinical and radiological performance of combined positron emission tomography/computed tomography (PET/CT) in patients with secondary and primary intraorbital tumours. METHODS 14 adults with secondary and 1 child with primary orbital masses underwent combined whole-body PET/CT. Radiopharmaceutical tracers applied were (18F)-fluorodeoxyglucose, (18F)-fluoroethylcholine (FEC) and (68Ga)-DOTATATE. Histopathology and/or all conventional radiographic work-up and clinical course served as standard of reference. Descriptive statistics and Fisher's exact test were used for analysis. RESULTS PET/CT detected all orbital masses. All 15 patients had malignant disease. Local osseous infiltration was correctly identified in 11 patients. Lymph node metastases were present in two of eight patients (25%) with haematogenous orbital metastases and in five of six patients (83%) with infiltrative carcinoma (p=0.05). Further distant metastases were present in all eight patients suffering from orbital metastases, but only one patient with infiltrative carcinoma (17%) presented with disseminated disease (p=0.003). In one metastasis, PET/CT excluded vital orbital tumour tissue after radiation therapy. Local recurrence was detected in another patient suffering from prostate cancer. CONCLUSION PET/CT is a sensitive tool for the detection and localisation of orbital masses, enabling assessment of both morphology and cell metabolism. Detailed imaging of the head and neck region with a small field-of-view should be performed when suspecting lymphatic metastases. As metastatic disease to the orbit is associated with advanced disease, focus should be laid on whole-body imaging for staging of these patients. Different radiopharmaceutical tracers can be applied to distinguish the origin of orbital metastases.

Abstract
Imaging evaluation of the postoperative orbit remains challenging even for the expert neuroradiologist. This article provides a simplified framework for understanding the complex postoperative appearances of the orbit, in an attempt to enhance the diagnostic accuracy of postoperative computed tomography and MR imaging of the orbit. Readers are familiarized with the normal appearances of common eye procedures and orbit reconstructions to help avoid interpretative pitfalls. Also reviewed are imaging features of common surgical complications, and evaluation of residual/recurrent neoplasm in the setting of oncologic imaging surveillance.
