Abstract
OBJECTIVE Temporal bone squamous cell carcinoma (TBSCC) is a rare malignancy with poor prognosis, and optimal treatment for advanced cases is uncertain. Our systematic literature review aimed to assess 5-year survival outcomes for advanced TBSCC across different treatment modalities. DATA SOURCES EMBASE, Medline, PubMed, and Web of Science. REVIEW METHODS A systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for articles published between January 1989 and June 2023. RESULTS The review yielded 1229 citations of which 31 provided 5-year survival data for TBSCC. The final analysis included 1289 patients. T classification data was available for 1269 patients and overall stage for 1033 patients. Data for 5-year overall survival (OS) was 59.6%. Five-year OS was 81.9% for T1/2 and 47.5% for T3/4 (P < .0001). OS for T1/T2 cancers did not significantly differ between surgery and radiation (100% vs 81.3%, P = .103). For advanced-stage disease (T3/T4), there was no statistical difference in OS when comparing surgery with postoperative chemoradiotherapy (CRT) (OS 50.0%) versus surgery with postoperative radiotherapy (XRT) (OS 53.3%) versus definitive CRT (OS 58.1%, P = .767-1.000). There was not enough data to assess the role of neoadjuvant CRT. CONCLUSION Most patients will present with advanced-stage disease, and nodal metastasis is seen in nearly 22% of patients. This study confirms the prognostic correlation of the current T classification system. Our results suggest that OS did not differ significantly between surgery and XRT for early stage disease, and combined treatment modalities yield similar 5-year OS for advanced cancers.

Study of Clinicopathological Presentation and Management of Malignant Tumours of the Ear and Temporal Bone at Tertiary Care Cancer Hospital. Indian J Otolaryngol Head Neck Surg 2022; 74:3662-3670. [PMID: 36742586 PMCID: PMC9895243 DOI: 10.1007/s12070-020-02346-2] [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: 10/27/2020] [Accepted: 12/21/2020] [Indexed: 02/07/2023] Open
Abstract
Tumors of the ear can be benign or malignant. They can occur on the external ear or in the ear canal, the middle ear, and inner ear. Tumors in different areas of the ear behave differently. They are rare which causes several problems in diagnosis and appropriate treatment. The purpose of this study was to analyze retrospectively the patients with malignant neoplasm of the ear. The main objectives of this study were to study the clinicopathological presentation of ear and temporal bone malignancy and to study the management of different types of malignancy of ear and temporal bone. This study is conducted at our tertiary care cancer hospital from Feb 2015 to Jan 2020. This study includes 15 patients treated for malignancy of the external and middle ear. The entire patient was thoroughly examined for malignancy. Details ENT examination was done. History of smoking and tobacco chewing asked. The patient factors considered in this study were age, sex, diagnosis, treatment (surgery, radiotherapy, and chemotherapy), complications, follow-up, and recurrence. This study includes [n = 15] patients. Due to a variety of malignant lesions of the ear and temporal bone they were classified into two groups, Superficial location lesions [n = 5] 3 of disease limited to pinna and 2 cases of primary of parotid origin involving pinna. Deep location involving external auditory meatus and middle ear [n = 12]. In this study of [n = 15] cases lowest age was 18 years. male and highest age was 75 years. male and most common age group was 56-65 years in which [n = 7] patients present. In this study we studied [n = 11] male patients and [n = 4] female patients. The most common symptom present was ear discharge [n = 8], the next common symptom was hard of hearing [n = 7]. A less common symptom was facial weakness [n = 3]. In sign, mastoid tenderness was commonest in [n = 5], and less common was facial palsy in [n = 3]. In our study of [n = 15] patients we did lateral temporal bone resection in [n = 5] patients, wide local excision of lesion in [n = 4] patients, lateral temporal bone resection with postero-lateral neck dissection with PMMC flap done in [n = 2] patients. In our study of [n = 15] cases of ear malignancy most common histopathology is squamous cell carcinoma [n = 12] cases, least were basal cell carcinoma [n = 1], melanoma [n = 1], and Rhabdomyosarcoma [n = 1]. Malignant tumors of the ear and temporal bone are rare. Neoplasm's of the external and middle ear constitutes a group of various histopathological and clinical tumors that differ in diagnostic difficulties, treatment, and prognosis. Surgery is the mainstay of treatment followed by reconstruction. Radiotherapy and chemotherapy play an adjuvant role in post-operative management in the high-risk category. Prognosis is worst as the tumor stage advances. And most of the cases diagnosis was often made in the advanced stage especially for middle ear tumors that diminished the possibility of effective treatment.

Abstract
Background T4‐classified squamous cell carcinoma (SCC) of external auditory canal (EAC) can potentially involve different anatomical structures, which could translate into different treatment strategies and survival outcomes within one classification. Our aim is to evaluate the clinical added value of T4‐subclasses proposed by Lavieille and by Zanoletti. Methods Retrospective data, including patients with primary operated cT4‐classified EAC SCC, was obtained from 12 international hospitals. We subclassified according to the T4‐subclasses. The treatment strategies, disease‐free survival (DFS) and overall survival per subclass were calculated. Results A total of 130 T4‐classified EAC SCC were included. We found commonly used treatment strategies per subclass according to Lavieille and the DFS seems also to differ per subclass. Subclass according to Zanoletti showed comparable treatment strategies and survival outcomes per subclass. Conclusion Our study suggests that the subclass according Lavieille might have added value in clinical practice to improve care of T4‐classified EAC SCC.

Abstract
Malignant tumors of the external auditory canal (EAC) are rare tumors in the head and neck. Delayed diagnosis is not uncommon because the symptoms of early tumors are nonspecific. Various surgical and oncological treatment modalities have been reported. Decision-making depends on pathological feature and stage of the lesions, patient’s general condition and preference, and physician’s experience and skill. Radical surgery is widely accepted as the primary treatment of choice. Postoperative radiotherapy is used more often to improve local and regional control of the disease. Chemotherapy is usually recommended for advanced disease, residual disease, and metastasis. Prognosis is affected by multiple factors such as TNM stage, surgical margin, pathological type and differentiation of tumor, involvement of facial nerve, and so on. Although the survival rate is improved significantly over the past several decades with the development of skull base surgery, neuroradiology, anesthesiology, and oncology, it remains challenging to diagnose and treat EAC malignancies due to the rarity, the local anatomical complexity of temporal bone, and the lack of standard TNM staging system.

Abstract
PURPOSE Primary: To determine the rate of occult cervical metastases in primary temporal bone squamous cell carcinomas (TBSSC). Secondary: to perform a subgroup meta-analysis of the risk of occult metastases based on the clinical stage of the tumour and its risk based on corresponding levels of the neck. METHODS A systematic review and meta-analysis of papers searched through Medline, Cochrane, Embase, Scopus and Web of Science up to November 2021 to determine the pooled rate of occult lymph node/parotid metastases. Quality assessment of the included studies was assessed through the Newcastle-Ottawa scale. RESULTS Overall, 13 out of 3301 screened studies met the inclusion criteria, for a total of 1120 patients of which 550 had TBSCC. Out of the 267 patients who underwent a neck dissection, 33 had positive lymph nodes giving a pooled rate of occult metastases of 14% (95% CI 10-19%). Occult metastases rate varied according to Modified Pittsburg staging system, being 0% (0-16%) among 12 pT1, 7% (2-20%) among 43 pT2 cases, 21% (11-38%) among 45 pT3, and 18% (11-27%) among 102 pT4 cases. Data available showed that most of the positive nodes were in Level II. CONCLUSION The rate of occult cervical metastases in TBSCC increases with pathological T category with majority of nodal disease found in level II of the neck.

Abstract
Objective Evaluation of the management and survival in patients treated for temporal bone squamous cell carcinoma (TBSCC) in a tertiary referral centre. Methods Forty-nine patients underwent primary treatment for TBSCC. Thirty-six patients underwent a lateral temporal bone resection (LTBR) or subtotal temporal bone resection (STBR). Overall survival (OS) and disease-specific survival (DSS) analysis were assessed. Results Five-year OS of the 49 patients was 39%. Five-year OS of the 36 patients who underwent LTBR or STBR was 46%. Tumour-free margins were achieved in all patients with T1 and T2 disease, in 59% patients with T3 tumours and 0% patients with T4 disease. Five-year DSS was 85% for all T1/T2 tumours, 53% for T3 tumours and 0% for T4 tumours. Clear resection margins was the only significant predictor of DSS in our cohort. Conclusions The mainstay of treatment for TBSCC is temporal bone resection with tumour free resection margins, with or without adjuvant radiotherapy. Survival is negatively influenced by non-radical resection. T1 and T2 tumours can be managed safely with LTBR. More advanced disease requires a more extensive resection, with a higher likelihood of non-radical resections and decreased survival rates.

Abstract
BACKGROUND The aim of the study was to identify the value of extensive resection and reconstruction with flaps in the treatment of locoregionally advanced lateral skull-base cancer. PATIENTS AND METHODS The retrospective case review of patients with lateral skull-base cancer treated surgically with curative intent between 2011 and 2019 at a tertiary otorhinolaryngology referral centre was made. RESULTS Twelve patients with locoregionally advanced cancer were analysed. Lateral temporal bone resection was performed in nine (75.0%), partial parotidectomy in six (50.0%), total parotidectomy in one (8.3%), ipsilateral selective neck dissection in eight (66.7%) and ipsilateral modified radical neck dissection in one patient (8.3%). The defect was reconstructed with anterolateral thigh free flap, radial forearm free flap or pectoralis major myocutaneous flap in two patients (17.0%) each. Mean overall survival was 3.1 years (SD = 2.5) and cancer-free survival rate 100%. At the data collection cut-off, 83% of analysed patients and 100% of patients with flap reconstruction were alive. CONCLUSIONS Favourable local control in lateral skull-base cancer, which mainly involves temporal bone is achieved with an extensive locoregional resection followed by free or regional flap reconstruction. Universal cancer registry should be considered in centres treating this rare disease to alleviate analysis and multicentric research.

Abstract
Background and aims Squamous cell carcinoma (SCC) of the temporal bone is a rare malignancy accounting for only 0.2% of head and neck cancers. There is currently no clear consensus on staging or common approach to management. It is the aim of this work to provide the readers with a review of the current literature on this malignancy. Methods A literature review was performed identifying 16 case series with patient numbers ranging from 12 to 124. A total of 708 patients were included in this review, 67% presented with advanced disease. 578 cases were managed operatively with lateral temporal bone resection, some underwent local resection alone in early stage disease. In all studies radiation therapy was used as an adjunct to some degree. Results More than half of studies reported 100% either 2-, 3- or 5-year survival for T1 and T2 disease with no nodal involvement. Survival correlated with disease stage and in five studies SCC differentiation was found to be a significant prognostic factor. Post-operative radiotherapy was found to improve survival in only one study. Conclusions Temporal bone SCC is a readily treatable malignancy in early stage disease, however late stage disease has a poor prognosis. Differentiation of the SCC and stage of disease at presentation appear to have the greatest influence on 5-year survival rates. Further work is required in both the identification of early stage disease and in the treatment of later T3 and T4 lesions.

Abstract
Squamous cell carcinoma of the ear canal is an entity that arises from the stratum spinosum; it is a rare neoplasm, with a low incidence presenting 1 to 6 cases per million inhabitants, so there is little literature on this pathology. The clinical presentation of temporal bone cancer is usually nonspecific, meaning that its diagnosis is always a late-stage discovery. The definitive diagnosis requires biopsy of the lesion for histopathological and immunohistochemical study to establish the behaviour and the degree of differentiation. We present the case of an adult female patient with a clinical history of osteoporosis, diagnosed with chronic otitis media of the left ear of years of evolution, accompanied by purulent secretion of the same ear that did not respond to multiple treatment regimens. The patient also presented with a headache of left temporal predominance refractory to conventional analgesia. Cranial CT scans showed an osteolytic lesion of the left temporal bone with dural invasion. After resection and biopsy of the lesion, moderately differentiated squamous cell carcinoma was confirmed.

Abstract
PURPOSE Evidence-based treatment recommendations for external auditory canal (EAC) carcinoma are lacking in available literature. This study aims to evaluate the clinical characteristics and long-term outcomes of EAC carcinoma in a tertiary referral centre in a period of 15 years and identify independent prognostic factors. METHODS Retrospective observational study enrolling all patients with primary EAC carcinoma who underwent primary surgical treatment at the Portuguese Institute of Oncology (Lisbon) between 2004 and 2018. Epidemiological, clinical, histopathological and surgical data were retrieved from clinical records and analysed. RESULTS Twenty-seven patients were identified, with a median age of 77 years (range 29-92 years) and a slight female predominance (59.3%). Squamous cell carcinoma (55.6%) was the most common histological type, followed by basal cell carcinoma (40.7%) and ceruminous adenocarcinoma (3.7%). Pittsburgh tumour staging was distributed as early stage in 51.9% (I: 40.7%; II: 11.1%) and advanced stage in 48.1% (III: 29.6%; IV: 18.5%). Median follow-up period was 21 months (interquartile-range: 47). Four patients (14.8%) showed recurrence; recurrence rate was significantly higher in individuals aged < 60 years (p = 0.025) and with lymphovascular invasion (p = 0.049). Median overall survival was 88 months and estimated 2-year and 5-year overall survival rates were both 66%. Survival rates were higher in early stage patients (p = 0.021) and in those without facial palsy (p = 0.032). CONCLUSION Based on the available evidence in this review, individuals aged < 60, facial nerve impairment, advanced stage lesions, presence of lymphovascular invasion and squamous cell carcinoma histology are all associated with poor outcome and may be considered when discussing optimal treatment strategies in patients with EAC carcinoma.

OBJECTIVES The rarity of temporal bone squamous cell carcinoma (TBSCC) precludes a clear understanding of the disease and approach to its management. This review provides general background on the disease and discusses the current and emerging oncologic and rehabilitative management options. DATA SOURCES PubMed literature review. METHODS A review of the current literature was conducted to assess and collate up-to-date information regarding TBSCC management. RESULTS TBSCC is a rare and aggressive disease arising in the ear canal, temporal bone, or extratemporal sites. Prior radiation, chronic ear disease, or habitual ear picking may contribute to primary disease development. Because the symptoms of TBSCC and benign otologic disease are similar, TBSCC diagnosis may be delayed, allowing the tumor time to spread throughout the anatomically intricate temporal bone. The extent of the disease is determined based on imaging and is usually staged with the Pittsburgh Staging System. Temporal bone resection with parotidectomy and neck dissection is the current standard of care. Survival is generally good for early disease and poor for advanced disease, but chemotherapy is emerging as a promising treatment option. Auditory rehabilitation with osseointegrated hearing aids is recommended at initial oncologic resection. CONCLUSIONS The knowledge of and outcomes for TBSCC have improved with time, but because of the aggressive nature of the disease and the anatomic intricacy of the temporal bone, TBSCC treatment is complex and should be delivered by a multidisciplinary team. Inter-institutional collaboration may accelerate research for this rare disease. LEVEL OF EVIDENCE 5.

Abstract
Squamous cell carcinomas of the temporal bone are rare malignancies. This is a case of clear cell squamous cell carcinoma. Otalgia, otorrhea, and hearing loss are the usual presenting symptoms. This case of temporal bone SCC was aggressive in nature and presentation.
Introduction Squamous cell carcinoma (SCC) of the temporal bone is a rare malignancy. Clear cell SCC is a rare variant of SCC of temporal bone in which no clear risk factor has been suggested as possible etiology. Otalgia, otorrhea, and hearing loss are the usual presenting symptoms of SCC of the temporal bone. Presentation of case This is a case is of a 62-year-old female who presented with a 6 months’ history of experiencing intermittent left hearing disturbance, loss of balance, persistent left tinnitus, left otalgia radiating to the lateral neck and post auricular swelling. Histology showed clear cell variant, well differentiated SCC. The patient’s tumor was found to be non-resectable due to the extensive invasion. The patient was referred for palliative therapy by medical and radiation oncology, however, the patient couldn't tolerate it. One month later she passed away. Discussion SCC of the temporal bone is a challenging clinical entity. It is diagnosed mainly by clinical and radiological assessment, and deep biopsies are used to confirm the diagnosis. Temporal bone SCC is usually diagnosed late due to delayed presentation. This case of temporal bone SCC was aggressive in nature and presentation. The presentation was different from the known triad of symptoms of temporal bone SCC which is offensive otorrhea, pain, and bleeding. Conclusion This case showed a very destructive and bizarre clinical presentation but more report of cases is needed to have a better characterization of the clinical presentation and prognosis of this variant of SCC of temporal bone.

Abstract
Objectives Lateral temporal bone resection (LTBR) has traditionally been performed en bloc in accordance with oncologic principles. Occasionally, this is not possible due to a low tegmen or lateralized vasculature. We sought to determine if outcomes of piecemeal and en bloc LTBR are comparable. Study Design Retrospective review. Setting Two academic medical centers. Subjects and Methods Multi-institutional retrospective cohort study. Current Procedural Terminology codes were used to identify patients with T1 to T3 squamous cell carcinoma of the external auditory canal (EAC) who underwent LTBR from 2005 to 2015. Kaplan-Meier curves were constructed to compare total survival between the 2 treatment approaches. Pairwise comparisons were performed using χ2 and Fisher exact tests (significance at P = .05), as appropriate. Results Twenty-five patients were identified. Ten patients underwent en bloc LTBR; 15 underwent piecemeal LTBR. Median follow-up time was 11 months (range, 1-60 months). There was not a significant difference in overall survival between en bloc (38.9 months; 95% confidence interval [CI], 22.7-55.2) compared to piecemeal (37.5 months; 95% CI, 21.1-53.9) procedures ( P = .519). Estimates of disease-free survival also did not reveal statistically significant differences: estimated mean disease-free survival was 48.1 months (95% CI, 33.7-62.6) in en bloc patients and 32.5 months (95% CI, 17.1-47.8) in piecemeal patients ( P = .246). Conclusion These data suggest that piecemeal resection can be considered for cases of squamous cell carcinoma involving the external auditory canal where anatomic constraints preclude a safe en bloc resection. Larger studies or studies with a longer follow-up time may provide improved insight into survival comparisons.

Abstract
OBJECTIVE To present outcomes of extensive surgery: lateral, subtotal, total petrosectomies in patients with temporal bone invasion resulting from specific primary cancers. STUDY DESIGN Retrospective case review. SETTING Four tertiary referral centers. MATERIAL 89 patients with cancer of the temporal bone treated between January 2006 and December 2010. INTERVENTION Multidisciplinary team approach including surgical resection, reconstruction, and postoperative radiotherapy. MAIN OUTCOME MEASURE Disease-specific survival, overall survival. RESULTS In 27.0% of the patients, relapse was reported, with an average of 6.3 months after surgery; 31 patients (34.8%) died during the follow-up. The average mortality was 22.1 months. Fifty-four patients (58.7%) stayed alive during the time of observation. The average survival time was 42.0 months. The median time of survival with relapse was 12 months (range: 1-51 months). The three-year disease-free rate was 38.0% and the overall survival rate was 58.7%. CONCLUSIONS Petrosectomy is an effective treatment for malignant temporal bone invasion. The probability of a good outcome was statistically decreased with a high T grade, positive margins, and salvage surgery. Younger age is connected with better prognosis. One of the major tasks remains to improve detection and to shorten the time to diagnosis, keeping in mind that symptoms are insidious and in younger people, the time before diagnosis was longer.

Abstract
AIM Prognostic factors, rational management, and the ongoing investigations regarding temporal bone squamous cell carcinoma (TBSCC) have been critically reviewed. BACKGROUND TBSCC is an uncommon, aggressive malignancy. Although some progress has been made in treating this aggressive tumor, the prognosis in advanced cases remains poor. MATERIALS AND METHODS A systematic search of the literature for articles published between 2009 and October 2014 was performed using the PubMed (http://www.pubmed.gov) electronic database. RESULTS Given the particular anatomical site of TBSCC, its prognosis is significantly influenced by any direct involvement of nearby structures. The extent of the primary tumor is generally considered one of the most important prognostic factors and it is frequently related to prognosis even more strongly than N stage. For TBSCC, biomarker investigations in surgical specimens are only just beginning to appear in the oncological literature. CONCLUSION Given the particular features of TBSCC, the sub-specialty of otologic oncology seems to be emerging as a defined area of practice involving multidisciplinary team comprising oto-neurosurgeons, head and neck surgeons, plastic surgeons, oncologists, radiotherapists, dedicated radiologists, and pathologists.

Abstract
OBJECTIVE To describe the clinical characteristics and management of patients with external auditory canal (EAC) squamous cell carcinoma (SCC) that arose after they received radiotherapy for nasopharyngeal carcinoma (NPC) and to compare them with primary EAC SCC patients. STUDY DESIGN Retrospective clinical analysis. SETTING Hospital. PATIENTS Nine irradiated NPC patients who subsequently developed secondary EAC SCC and 41 primary EAC SCC patients at a single hospital. INTERVENTION Clinical characteristics and management outcomes of patients were reviewed. MAIN OUTCOME MEASURES Clinical manifestations, regions of tumor involvement, the pathological staging, cumulative overall survival rates, Kaplan-Meier method, log rank test, and Mann-Whitney U test. RESULTS The most common symptoms of both groups were otorrhea, otalgia, and hearing loss. The region most involved in both groups was the EAC. The proportions of early stage (T1,T2) tumors in the post-irradiated and primary EAC SCC group were 56 and 22%, respectively. The 6-month, 1-year, 2-year, and 3-year cumulative overall survival rates of the post-irradiated EAC SCC group were 100, 100, 89, and 89%, respectively. The incidence of radionecrosis was higher in the post-irradiation EAC SCC group than in the primary EAC SCC group. CONCLUSIONS Post-irradiation EAC SCC has similar symptoms and invades similar regions as primary EAC SCC. The proportion of early stage tumors in the post-irradiated EAC SCC group was higher than that in the primary EAC SCC group. High incidence of radionecrosis was observed after the second course of radiotherapy. Aggressive surgical treatment is strongly recommended, but adjuvant radiotherapy for early stage EAC SCC should be provided cautiously.

Abstract
Squamous cell carcinoma (SCC) of the external auditory canal (EAC) is rare, usually presents at an advanced stage, and is a more aggressive tumor with poor prognosis. The University of Pittsburgh TNM staging system commonly used in prognostication is not perfect, and more accurate biomarkers predicting prognosis are needed. Tumor budding is an established negative prognostic factor at the invasive front in colorectal cancer. Moreover, immunohistochemical studies showed that laminin 5-γ2 (Ln5-γ2) is expressed at the invasive front in tumor or tumor budding cells. We assessed the prognostic significance of tumor budding and Ln5-γ2 expression by performing Ln5-γ2 immunohistochemistry and evaluated the degree of tumor budding in pre-treatment biopsy specimens, and investigated their correlations to clinicopathological parameters in patients with SCC of the EAC. Patients whose tumors had high budding grade and Ln5-γ2 expression had significantly shorter survival times. Budding grade was significantly correlated with Ln5-γ2 expression. Multivariate analysis revealed that high budding grade predicted poorer prognosis regardless of disease stage. Our results suggested that budding grade and Ln5-γ2 expression can be used as indicators of poor prognosis in patients with SCC of the EAC.

Abstract
PURPOSE Temporal bone squamous cell carcinoma (TBSCC) is an uncommon, aggressive malignancy with a significant recurrence rate. We reviewed our experience with recurrent TBSCCs. MATERIALS AND METHODS Clinicopathological and therapeutic variables potentially associated with disease-free survival (DFS) and disease-specific survival (DSS) were assessed in 17 TBSCC patients who died of their disease after treatment. RESULTS TBSCC recurrences were treated with surgery in 12 cases (palliative in 11, with curative intent in 1) and palliative chemotherapy in 5; the median DFS and DSS were 6 and 16 months, respectively. The mean DFS and DSS were longer in patients who had primary lateral temporal bone resection (LTBR) rather than subtotal temporal bone resection (STBR) (p=0.0173 and p=0.03, respectively). Patients given non-surgical palliative treatment for recurrences had a longer mean DSS than those who underwent surgery (trend toward significance, p=0.09). CONCLUSIONS Our results reflect the aggressive nature of TBSCC recurrences. Our findings seem to support the use of non-surgical treatments (chemotherapy, radiotherapy, or specialist palliative care) in patients with loco-regionally advanced recurrent TBSCC. Salvage surgery might be considered for early recurrences when radicality is still achievable. Precise guidelines for the rational follow-up of surgically-treated TBSCCs need to be shared between tertiary centers.
