Amyloidosis of the upper aerodigestive tract

OBJECTIVES/HYPOTHESIS: To delineate the clinical and pathologic characteristics of upper aerodigestive tract amyloidosis with particular attention to laryngeal amyloidosis. STUDY DESIGN: Retrospective chart review of patients with amyloidosis of Thomas Jefferson University and its affiliated hospitals. MATERIAL AND METHODS: The charts of 16 patients with upper aerodigestive tract amyloidosis identified from the databases of the Thomas Jefferson University pathology department were reviewed and included in the study. RESULTS: Sixteen patients (9 male and 7 female, with an average age of 49.8 years) with upper aerodigestive tract amyloidosis were identified. The most common site of amyloid involvement was the larynx. Consequently, patients most commonly presented with hoarseness (14 of 16). All patients underwent surgical removal of the amyloid deposits. Fourteen patients had primary localized amyloidosis. Two experienced systemic involvement. Seven of the 16 patients developed recurrences requiring further treatment. CONCLUSIONS: Amyloidosis of the upper aerodigestive tract generally behaves as a benign, localized condition treatable by surgical resection. Regular follow-up with laryngoscopy is indicated for early diagnosis of recurrence, and multiple surgical procedures may be required to control symptoms.     

Amyloidosis of Waldeyer's ring and larynx

Amyloidosis of the upper aerodigestive tract is relatively rare. A case of localized amyloidosis involving all components of Waldeyer's ring with added laryngeal involvement is described. This has not been previously reported. A literature review of this conditions is presented.     

Management of laryngeal amyloidosis

Amyloidosis of the upper aerodigestive tract is rare. However, the larynx is the commonest site within the upper airways to be affected. Three cases of uncomplicated primary amyloidosis of the larynx and one case of laryngeal amyloidosis with more generalized dissemination throughout the head and neck are presented. In this article the different presentations of laryngeal amyloidosis and principles of management of this condition at that site are highlighted.     

Analysis of prognostic factors for Tis-2N0M0 early glottic cancer with different treatment methods

IntroductionIn many regions, laryngeal carcinoma is a common upper respiratory tract cancer, most commonly involving the glottic region. The treatment of early glottic cancer includes radiotherapy, open surgery and laryngeal laser microsurgery. However, the preferred treatment for early glottic cancer is still controversial.ObjectivesTo study the factors affecting the 5-year survival rate of T_is-2N₀M₀ early glottis cancer and to demonstrate the oncological safety of different treatments.Methods144 patients with early glottic cancer were analyzed retrospectively. All patients were clinically node negative. 53 patients underwent open surgery, transoral CO₂ laser microsurgery in 46 cases and radiotherapy in 45 cases. The patients were followed up for 26 ? 84 months, with an average follow-up period of 62.9 months.ResultsThe 5-year overall survival was 82.6%. The 5 year survival rates of open surgery, laser microsurgery and radiotherapy were 83.0%, 82.6% and 82.2%, respectively. There was no significant difference in 5-year survival rate among the three treatments (p = 0.987). In multivariate analysis, age, T-stage, pathological grading, and anterior commissure involvement were important prognostic factors for early glottic cancer.ConclusionThere was no significant difference in 5 year survival rate among patients treated by either radiotherapy, laser microsurgery or open surgery for early glottic cancer. We urge more attention to the age, T-stage, pathological grade, and anterior commissure involvement of the patients.

Surgical management of localized amyloidosis

OBJECTIVE: To demonstrate the role of two-dimensional reconstruction images on computed tomography (CT) in the treatment planning for laryngeal amyloidosis. To discuss the treatment for isolated laryngeal amyloidosis and compare the role of endoscopic versus an open surgical approach to management. STUDY DESIGN: Retrospective review. METHODS: The medical records from 1984 to the present with the diagnosis of localized respiratory tract amyloidosis at Geisinger Medical Center were reviewed. RESULTS: Five previously unpublished cases of localized laryngeal amyloidosis were identified with the supraglottic region the major site of involvement. Hoarseness and airway compromise were the presenting symptoms. CT two-dimensional reconstruction imaging was used to evaluate two cases with extensive laryngeal involvement that required an external surgical approach to relieve symptoms. CONCLUSIONS: Localized laryngeal amyloidosis is a rare disease that requires surgical management when symptomatic. CT two-dimensional reconstruction can be helpful in detailing the extent of disease and planning surgery. A lateral external supraglottic approach has been found to be successful in treating patients with large supraglottic masses.     

Primary amyloidosis presenting as a nasopharyngeal mass.

Amyloid is defined as a pathologic proteinaceous substance which, when deposited between the cells of tissues and organs, leads to various clinical conditions. Immunohistochemistry has allowed for better classification and understanding of the pathophysiology of amyloidosis. In the upper aerodigestive tract, amyloidosis is a rare condition occurring most frequently in the larynx. We present the case of a 42-year-old woman with complete nasal obstruction due to primary nasopharyngeal amyloidosis. This represents the first reported case of primary nasopharyngeal amyloidosis containing both the lambda and kappa immunoglobulin light chains. The clinical and radiologic findings, as well as the management of primary amyloidosis of the upper aerodigestive tract, will be discussed. A review of the literature pertaining to nasal and nasopharyngeal amyloidosis will be presented.     

CO_2激光与喉显微手术治疗声带息肉的疗效对比

Laryngeal epidermoid carcinoma associated with juvenile laryngeal papillomatosis

The speculation whether juvenile laryngeal papillomatosis may transform into or be associated with epidermoid carcinoma is explored. We document a case of invasive laryngeal carcinoma arising in preexisting juvenile laryngeal papillomatosis. After multiple childhood laryngoscopies and a tracheotomy, a 54-year-old, 30-pack per year smoker, who had never received radiation therapy, developed a florid exophytic transglottic squamous cell carcinoma. Histologically, the invasive epidermoid carcinoma was surrounded by a field of papillomata with varying degrees of atypical changes. After total laryngectomy, isolated papillomata were found in the lower trachea. There were no cervical lymph node metastases. No postoperative radiation therapy was given. Persistent squamous papillomata in the tracheostomy site, the lower trachea, and the posterior pharynx were treated with the CO2 laser. We emphasize the need to maintain a high index of suspicion for malignancy. In addition, we review the problem of benign papillomata in the aerodigestive tract following laryngectomy.     

Amyloidosis of the larynx. A clinical case and literature review

The larynx is a rare site of deposition for amyloidosis. We are reporting the clinical case of a 73 years female with hoarseness of 2 years evolution due to a laryngeal mass which was informed as located primary amyloidosis after anatomopathologic exam (AP) and its extension study. A laryngeal microsurgery was performed and then we proceeded to send the patient to Internal Medicine Service with periodic controls by ORL. Surgery is the treatment of choice by microsurgery, laryngofissure or Laser with local excision. The prognosis of localized forms is better than systemic ones although recurrences are common and it is recommended a long-term follow-up. A bibliographic review about this pathology has been made.     

Tuberculosis in the upper aerodigestive tract and human immunodeficiency virus coinfections

OBJECTIVE: To describe the clinical manifestations of tuberculosis in the upper aerodigestive tract. DESIGN: Retrospective chart analysis. SETTING: Srinagarind Hospital, Department of Otolaryngology, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand. METHODS: A review of medical records of patients diagnosed with mycobacterial infection of the upper aerodigestive tract between January 1991 and December 2000. MAIN OUTCOME MEASURES: Presenting symptoms, clinical findings, pathologic findings, pulmonary involvement, and outcome of treatment. RESULTS: Forty-five patients presented with upper aerodigestive tract tuberculosis. The nasopharynx was involved in 23 patients, the larynx in 16, the tonsils in 6, and the soft palate in 1. One patient had tuberculous infections in both the nasopharynx and tonsils. The mean duration of symptoms before diagnosis was 2.1 months. The pathologic findings included caseous granuloma and/or positive acid-fast bacilli (AFB) in 39 cases and chronic granulomatous inflammation with negative AFB in 6 cases. Pulmonary tuberculosis was found in 19 of the 36 patients who underwent radiography. A positive serologic test for human immunodeficiency virus (HIV) infection was found in 4 of 26 patients. These 26 patients, who received a full course of treatment, responded well. CONCLUSION: The most common site of tuberculosis in the head and neck involved the cervical lymph nodes and nasopharynx. Upper aerodigestive tract tuberculosis is difficult to differentiate from carcinoma; thus, tissue biopsy is necessary for a definite diagnosis. Chest radiography and screening for HIV infection are recommended in all patients with upper aerodigestive tract tuberculosis.

Localized laryngeal amyloidosis. Endoscopic surgery with CO2 laser

Laryngeal amyloidosis is a very rare disease. In the upper airways, the most common localization is the laryngeal organ, particularly the supraglotic region. Usually laryngeal amyloidosis is a localized primary form, although it has occasionally been reported in conjunction with system amyloidosis. We are reporting a new case of localized primary laryngeal amyloidosis in the right arytenoid mucosa in a 66 years old woman who underwent CO2 laser endoscopic surgery.     

History of the carbon dioxide laser in otolaryngologic surgery

The review of recent history shows that since the initial discovery of the principle of the laser, rapid dissemination and application of this modality in the field of medicine have occurred. The use of laser energy has become an established technique in microsurgery and endoscopic surgery, particularly in the field of otolaryngology and head and neck surgery. Laser instruments and surgical techniques and experience are becoming increasingly widely appreciated. All these developments are a tribute to the imagination and determination of a few individuals who were instrumental in recognizing the potential of laser energy for surgical application and in developing and using this new modality in clinical surgery. The major developments in laser surgery include early laboratory studies of laser surgical applications and their effects, the invention and development of instruments allowing application of laser energy in a variety of surgical settings, particularly the upper aerodigestive tract, and clinical studies confirming the efficacy of laser surgery. Other significant developments include the successful application of laser surgery in the eradication or control of selected cancers in the upper aerodigestive tract, including the tracheobronchial tree. Although a firm foundation for laser surgery is well established, its future offers a wide vista of new opportunities.

目的探讨原发性喉淀粉样变的临床特征及治疗方法。方法回顾性分析空军军医大学附属唐都医院2017年4月—2019年1月收治的喉淀粉样变4例临床资料,并进行相关文献复习。结果4例患者病变组织均经手术切除,其中2例喉正中裂开肿物切除,2例支撑喉镜下二氧化碳激光手术切除,病理结果示淀粉样变,无喉气管功能损伤,无临床及实验证据表明有系统性淀粉样病变。随访时间3个月至2年,未见肿物复发。结论孤立性喉淀粉样变是一种罕见的良性肿瘤,需要同其他良恶性喉肿瘤相鉴别,治疗前需排除全身系统性淀粉样病变。治疗方案以手术为主,治疗策略应该偏保守,以保留器官功能为前提。     

Impact of re-resection for inadequate margins on the prognosis of upper aerodigestive tract cancer treated by laser microsurgery

OBJECTIVES: Positive or uncertain surgical margins left untreated have a distinct prognostic relevance in squamous cell carcinoma of the upper aerodigestive tract. An advantage of transoral laser microsurgery is that it can be easily repeated if inadequate resection margins are found postoperatively. The present study investigates the impact of laser surgical reresection on the outcome of patients. STUDY DESIGN: The authors conducted a retrospective unicenter study. METHODS: A review of 1,467 patients with squamous cell carcinoma of the upper aerodigestive tract who were initially treated by transoral laser microsurgery with curative intent between August 1986 and December 2002 was conducted. Locoregional control as well as TNM adjusted and overall survival were analyzed using the Kaplan-Meier method. RESULTS: Three hundred eighty-six patients have required reresection to obtain clear surgical margins, in 70 of whom residual carcinoma has been detected in revision specimens. Patients without need for revision and those in whom revision specimens were found tumor-free had an almost identical locoregional control (P = .4611). In patients with positive revision specimens, however, locoregional control was significantly worsened (P = .0058). Neither the need for reresection nor the detection of further tumor tissue in revision specimens affected TNM adjusted or overall survival. CONCLUSIONS: Survival of patients was similar whether clear resection margins were reached within the first surgical step or with revision surgery. However, patients in whom reresection specimens contained residual carcinoma had an increased risk of locoregional failure and should undergo a further reresection or at least a very close follow up.     

Lokale und regionäre Rezidive von laserchirurgisch behandelten Plattenepithelkarzinomen des oberen Aerodigestivtrakts

Introduction

The aim of the present study is to identify clinical factors that influence the incidence and the prognosis of local and regional recurrences.

Patients and methods

The data of 1,426 patients with newly diagnosed squamous cell carcinoma of the upper aerodigestive tract who were treated by curative laser microsurgery between August 1986 and December 2002 were reviewed.

Results

In 381 patients (27%), tumor recurrences were detected during follow-up. The frequency of local as well as regional recurrences significantly correlated with the initial stage of tumors. Recurrences of advanced carcinomas occurred considerably sooner than those of stage II and I cancer. During the 4th year of follow-up, patients with early stage disease had a recurrence rate twice as high as those with advanced carcinomas. Survival with recurrence was adversely affected by adjuvant radiotherapy as part of initial treatment, simultaneous local and regional manifestation of recurrence, male sex, advanced stage of initial disease, and by oral or hypopharyngeal site of the primary tumor.

Conclusion

Early carcinomas of the upper aerodigestive tract recur at a lower rate than advanced stage diseases, but after a longer mean latency period. As a consequence, these patients should receive close follow-up also during the 3rd and 4th years after treatment, particularly as the prognosis of their recurrences is most often favorable.     

Laser in treatment of laryngeal amyloidosis

Amayloidosis is the extracellular deposition of the fibrinous protein amyloid in one or more body sites. Amyloidosis may broadly be classifed as either primary or secondary. Primary amyloidosis is idiopathic (56 %), whereas the secondary form is associated with a chronic inflammatory or infectious process (5%). Amyloidosis is also related to multiple myeloma (26%), senescence (5%) and where tumor like deposits occur in isolated organ without systemic involvement (8%). Laryngeal amyloidosis is a rare disease. Surgery has been the mainstay of treatment either endoscopicalfy or by an external neck approach. One case of laryngeal amyloidosis, treated with endolaryngeal microsurgery and carbon dioxide laser is presented with a follow up of 8 years.
