A patient with adult-onset recurrent respiratory papillomatosis (RRP), initially diagnosed at age 28 years, was treated with radiation therapy due to the rapid regrowth of lesions. Following 6 years of apparently inhibited growth, papilloma recurred, and squamous carcinoma was diagnosed from a laryngeal biopsy. A spontaneous laryngocutaneous fistula developed, and laryngectomy was performed 14 years after irradiation. The laryngectomy specimen was snap frozen and representative tissues were stored frozen for viral studies. The larynx was whole-organ sectioned for histologic examinations; residual papilloma, as well as carcinoma, was observed. Koilocytosis and other virus-associated histologic changes were also found. HPV capsid antigen was present in papilloma, carcinoma, and clinically normal epithelium. HPV nucleic acids, conforming to HPV type 6, were present in keratin pearls and dysplastic cells. According to prior reports, carcinoma developing in preexisting papilloma arises from juvenile-onset RRP. Irradiated papilloma develop cancer at about 10 years, and the patients rarely survive. Nonirradiated cases develop cancer after 30 years, and some develop papilloma in the hypopharynx and trachea, but most patients survive. Irradiation is not an obligatory precursor for malignant transformation of cancer; however, until now there have been no case reports of favorable outcome after irradiation of papilloma. 相似文献

Laryngeal papilloma in children is a frequent disease caused by human papilloma virus (HPV) type 6 or type 11. This disease has a tendency to recur and the changes are histologically benign. In some cases papilloma may affect the lower levels of the respiratory tract. In this study, among 90 patients treated for laryngeal papillomatosis, in four children papilloma of trachea, bronchi and lung tissue were detected in endoscopic and radiological examination. This constitutes 4.4% of all patients. Compact nodules and acquired cysts between 5 and 50 mm long were found in chest X-rays and in computerised tomography. These cysts appeared from 4 to 8 years after establishing a diagnosis of laryngeal papilloma, and 1 year after recognising papilloma in the trachea. In all four children the presence of nodules and cysts in the lungs was preceded by recurrent pneumonia, emphysema or atelectasis of the lungs. All children with laryngeal papillomatosis should have a chest X-ray. Detection of acquired cyst-like changes in lung tissue in children with laryngeal papillomatosis is a warning of future papilloma in the trachea and bronchi, with involvement of lung tissue. In differential diagnosis of these changes in the lungs we should take into consideration the presence of papilloma in the bronchi. A prognosis of papillomatosis in the lower airways in children is always serious. 相似文献

BACKGROUND: The treatment of recurrent laryngeal papillomatosis still presents an important therapeutic problem. This primarily benign disease of the larynx is caused by an infection with the human papilloma virus (HPV) and forms epithelial neoplastic papillomas. Therapy in larynx obstructing papillomatosis usually requires laser ablation. Cidofovir acts virustatically as an nucleosidanalogon. Currently pilot studies investigate the effectiveness of intralesional Cidofovir injection. PATIENTS AND METHODS: The present study covers the period from October 2001 to March 2003. Seven patients, age of five to 70 years, were treated with intralesional injections of Cidofovir after microlaryngoscopic ablation of laryngeal papillomas. In all patients papillomatosis was confirmed histologically and a clinical-phoniatric examination and a photo documentation pre- and postoperatively was carried out. We treated patients to a maximum of six sessions. RESULTS AND CONCLUSIONS: After three to six sessions of laser ablation of the papillomas and intralesional injections with Cidofovir a distinct papilloma reduction could be observed in all patients and in two cases a complete remission was achieved. The follow-up period of seven to 15 months revealed no recurrent laryngeal papillomatosis. The majority of patients showed a defined voice improvement. There were no local or systemic side-effects caused by the virustatic drug. Intralesional injection of Cidofovir appears to develop into a promising adjuvant therapy option in recurrent laryngeal papillomatosis. First results of the study seem to achieve a considerable reduction of the previously high rate of recurrence of laryngeal papillomatosis. 相似文献

Recurrent respiratory papillomatosis (RRP) is a histologically benign disease of the larynx, trachea, and bronchi. Here we report on the histologic and molecular characteristics of 7 cases of malignant transformation of RRP to squamous cell carcinoma (SCCA). The clinical histories of 7 patients with RRP who developed SCCA were carefully reviewed. Sequential biopsies were available from 5 of the 7 cases of spontaneous transformation of RRP to SCCA and were reviewed. In addition, p53 protein overexpression and human papillomavirus (HPV) typing for all cases was examined. The average age of patients with juvenile-onset RRP was 3 years, and that of patients with adult-onset RRP was 31 years. The average age of onset of transformation to SCCA was 28 years. All patients had laryngeal involvement with RRP, and 3 of the 7 patients had tracheal extension of disease. Five patients were tracheotomy-dependent. Four of the 7 patients developed SCCA of the lung, while 3 patients developed laryngeal SCCA. There was no consistent histologic progression from squamous papilloma to papilloma with dysplasia, and all but 1 of the SCCAs were well differentiated. The overexpression of p53 protein was variable in each of the 5 patients. We detected HPV types 6/11 in papillomas from 3 patients, and HPV types 6/11, 16/18, and 31/33/51 in a papilloma of a fourth patient. No HPV DNA was detected in papillomas of 2 patients. We found HPV 6/11 in 4 of the carcinomas. We conclude that the spontaneous transformation of RRP to SCCA is not characterized by a histologic progression through dysplasia over time. Transformation can result in the loss of HPV expression. It does not appear that p53 is a molecular marker for monitoring the transformation process. Thus, these cancers may be very difficult to diagnose histologically and clinically early in the course of the transformation of the disease. 相似文献

We examined 12 recurrent respiratory papillomatosis patients, who were undergoing treatment for recurrence of their disease, for the presence of human papillomavirus (HPV). Biopsies were obtained from their respiratory papillomas and nondiseased sites (NDS) of the respiratory tract: the nasopharynx, posterior tonsillar pillar, aryepiglottic fold, cervical trachea, intrathoracic trachea, and bronchi. The presence of HPV DNA was determined by using the ViraPap/ViraType DNA hybridization procedure. Two thirds of the patients were infected with HPV 6/11 in either the diseased papilloma or NDS: 50% of patients with papilloma specimens typed positive (6 of 12), and 40% of the patients typed HPV-positive in one or more biopsies from the NDS (4 of 10). No single NDS was more likely to be infected with HPV than any other. No oncogenic HPV types 16/18 or 31/33/35 were detected in the papillomas or NDS of these patients. Only patients with multiple, and not isolated, papilloma involvement were found to harbor HPV DNA in NDS; and 80% of those with infected NDS, compared to 20% of those without infected NDS, required a shorter (no more than 3 months) surgical treatment interval. Our results show that HPV infection frequently persists in adjacent, clinically normal sites, and suggest that the extent of NDS involvement may predict both the extent of disease and the likelihood of recurrence. 相似文献

OBJECTIVES: Papillomas of the larynx include solitary laryngeal papilloma and recurrent respiratory papillomatosis. This study investigated the incidence of malignant transformation and assessed possible risk factors for laryngeal papillomas. STUDY DESIGN: A prospective, longitudinal study. METHODS: Twenty-six consecutive laryngeal papilloma patients were prospectively studied for 5 or more years, and each patient was periodically examined at 3 to 6 month intervals. A detailed epidemiologic questionnaire was administered at the initial visit. After enrollment, tissue obtained during each laryngeal surgery was examined by polymerase chain reaction assay for human papilloma virus (HPV) and typing. RESULTS: During 237 person-years of follow-up, six new, pathologically confirmed cases of laryngeal carcinoma were ascertained (incidence 2.5/100 person-years), and all were associated with HPV-6 or HPV-11. Malignant transformation revealed no correlation with the following: age less than 3 years at diagnosis, sex, history of tobacco use, history of alcohol consumption, family history of laryngeal cancer, or type of laryngeal papilloma. Laryngeal papilloma without demonstrable HPV DNA was the only significant risk factor for malignant transformation (P < .05). The cumulative risk of malignant transformation in subjects without demonstrable HPV DNA was significantly higher than that in HPV-positive patients (relative risk, 8.0; 95% confidence interval, 1.1-60.3; P = .05). CONCLUSIONS: A relatively high incidence of malignant transformation of laryngeal papilloma was noted in Taiwanese patients. Patients without demonstrable HPV DNA require more frequent follow-up and may benefit from anti-HPV vaccinations. 相似文献

Recurrent respiratory papillomatosis is a viral-induced disease, associated with exophytic epithelial lesions affecting the upper airways. Problem of treatment is the high recurrence of papilloma growth after surgical removal; therefore, adjuvant therapy schemes have been established. We used cidofovir, 7.5 mg/ml, in adjuvant therapy in the past years. Out of 31 adult patients treated with the drug, 26 (83.9 %) are at the moment in complete response. 19 (73 % of pts with CR) of those 26 patients were cured with a number of injections between 1 and 4 (mean 2.5). We did not see any clinical manifestation of renal toxicity or neutropenia (superinfection) necessitating a blood test. Six patients presented dysplasia during the treatment with the drug, while six patients had dysplasia prior to cidofovir injection. Due to recurrent nature of the disease and the high number of mechanical and laser surgeries required we treated one tracheal stenosis, two scarred larynx, and two glottic synechiaes. There is still an ongoing discussion within the European Laryngological Society about the effectiveness and possible side effects of this drug. Results show promising long-term effects of adjuvant use of cidofovir, without any relevant side effects. 相似文献

OBJECTIVE: Determination of early prognostic factors in patients with recurrent respiratory papillomatosis is extremely important, so the major goal of our prospective, multicentre study was to evaluate (1) the feasibility of various factors to determine prognosis of the clinical course, as well as (2) the response to interferon-alpha therapy in recurrent respiratory papillomatosis. METHODS: Forty-two patients with recurrent respiratory papillomatosis were treated with interferon-alpha (3 MU/m(2) three times per week; mean therapy duration was 2.7 +/- 1.8 years) in 1983-1994 and followed-up until 2003. Human papilloma virus (HPV) type, recurrent respiratory papillomatosis severity and 2',5'-oligoadenylate synthetase activity were determined by standard methods and analysed for correlation with the results of long-term clinical outcome. RESULTS AND CONCLUSION: Patients with HPV type 11, a severity score >4, a high number of surgical procedures prior to interferon-alpha therapy and a high basal 2',5'-oligoadenylate synthetase activity should be considered at high risk of an aggressive clinical course, often with spread to lower airway passages, malignant transformation and death. Human papilloma virus type, score for recurrent respiratory papillomatosis severity, number of surgical procedures and 2',5'-oligoadenylate synthetase activity showed significant association with response to interferon-alpha therapy and the long-term clinical course, so these factors have value in predicting prognosis in recurrent respiratory papillomatosis. 相似文献

Squamous cell carcinoma (SCC) in larynx is rare with children and adolescents. Usually larynx cancer is common with male smokers in the 7th decade. Among patients with no history of tobacco and/or alcohol consumption several factors have can play a role in the outbreak of laryngeal cancer: such as individual predisposition, radiation, gastroesophageal reflux, viral infection, dietary factors and environmental influences. In literature only few cases of laryngeal cancer with children are reported. Recent studies show that the most frequent laryngeal malignancy is the embryonal rhabdomyosarcoma. Besides the recurrent respiratory papillomatosis (RRP) based on an infection with human papilloma virus (HPV) types 6 and 11 (low risk) and types 16 and 18 (high risk) is known for a possible malignant transformation towards a SCC. HPV type 26 is only reported as low risk type HPV associated with cervical cancer. Final diagnosis often takes a long time. Initial symptoms such as hoarseness, cough or shortness of breath are often referred to more typical pediatric diseases or laryngeal development. 相似文献

The type of human papilloma virus (HPV) was determined in 26 children aged between 1 year 10 months to 15 years 5 months suffering from recurrent respiratory papillomatosis (RRP). Polymerase chain reaction identified DNA of HPV type 6, 11, 16 and 18. HPV DNA was detected in all the patients including fifteen patients infected with HPV type 11; seven patients infected with HPV type 6; four children infected with HPV type 6 and 11. Types 16 and 18 of HPV were not detected. The analysis of RRP course has found that laryngeal papillomatosis runs a more aggressive course in cases with HPV type 11 infection than in those with HPV type 6. 相似文献

Human papilloma virus (HPV) infection in the larynx often requires frequent surgical procedures in order to keep voice quality
reasonable. The purpose of this study was to evaluate the speaking voice quality of patients with longstanding recurrent laryngeal
papillomatosis (RLP). The patients were seven males with adult-onset RLP whose disease had lasted over 5 years, and who were
free of papilloma at the time of examination. Each patient had an age- and gender-matched control with similar smoking habits.
Voice samples were recorded and acoustic analysis as well as perceptual listening test were performed. In our series a perceptual
test discriminates between normal and pathological voice quality more precisely than acoustical voice analysis. It appears
that the voice of the papilloma patient, even after frequent phonosurgical operations, is not deviant from the normal when
analyzed acoustically, but perceptual assessment shows that overall quality is less than optimal, and roughness and breathiness
are increased. 相似文献

The study of indinol efficacy in antirecurrence therapy of respiratory papillomatosis was performed in 46 children aged 2-14 years. The treatment lasted at least 12 weeks. Duration of a recurrence-free period before and after indinol administration was analysed. The response was observed in 30 (65.2%) patients. In 5 (10.9%) patients the remission continued from 2 to 3 years 10 months. In 25 (54.3%) patients recurrence-free period increased 1,5-6-fold. Side effects were not registered. Simple in use, cheap, well tolerated, usable with other treatments, indinol is recommended as a method of choice in antirecurrence treatment of recurrent respiratory papillomatosis. 相似文献

Recurrent laryngeal papillomatosis is a benign disease of the larynx often leading to organic and functional restrictions.
The therapeutic treatment of choice in larynx-obstructing papillomatosis is at present surgical laser ablation. The effectiveness
of adjuvant intralesional injection of the virustaticum Cidofovir has been investigated recently in a variety of therapeutic
models. The present case study deals with the treatment of recurrent laryngeal papillomatosis by means of surgical laser ablation
of the laryngeal papillomas with adjuvant local injection of the virustaticum Cidofovir (dose of 5 mg/1 ml). Within the period
from October 2001 to August 2004, ten patients aged between 5- and 70 years were treated with intralesional injections of
Cidofovir. Papillomatosis was confirmed histologically in all cases, and the virus types were defined in part. Each of the
patients underwent clinical–phoniatric examinations and was photographed for documentation. After 2–7 treatments with surgical
laser papilloma ablation and intralesional Cidofovir injections, all patients showed a definite papilloma reduction, while
in six cases complete remission was achieved. During the follow-up period of 8–30 months, not a single recurrence of the laryngeal
papillomatosis occurred. In the majority of patients, a clear improvement in the voice was achieved. There were no local or
systemic side effects caused by the virustaticum. Intralesional injection of Cidofovir is an adjuvant, but not a curative
therapeutic option in recurrent laryngeal papillomatosis. Remission of previously frequently recurrent laryngeal papillomas
can be achieved, but recurrence after longer treatment-free intervals is also possible.

Intranasal schneiderian exophytic squamous papillomatosis is rare and often secondary to human papilloma virus infection.
Treatment usually consists of repeated surgical or endoscopic excisions due to recurrences. The use of intravenous or intralesional
or topically applied cidofovir, a cytidine nucleotide analogue suppressing viral replication, alone or as adjuvant therapy
has been proposed and described in the literature for the treatment of other human papillomavirus (HPV)-related lesions. We
firstly describe a successful combined approach of surgery and topical cidofovir for recurrent nasal HPV-related exophytic
squamous papillomatosis in a HIV-infected patient. As no untoward effects were encountered this therapeutical option should
be considered in the management of recurrent nasal papillomatosis in HIV-infected patients. 相似文献

Seven patients, aged 2-7 years, with active recurrent respiratory papillomatosis (RRP) attending the University of Michigan Pediatric Otolaryngology Clinic were studied to determine if human papillomavirus (HPV) is harbored in sites of the upper aerodigestive tract other than in the laryngeal papilloma itself. We also determined if close family members had detectable virus in their oral cavities. Noninvasive swabs of buccal mucosa, posterior pharynx, nasal vestibule, and tonsillar pillar of patients, as well as buccal mucosa and posterior pharyngeal swabs of family members were studied. Swabs of the patients' papillomas served as the positive controls. HPV was detected using polymerase chain reaction (PCR) amplification and Southern hybridization techniques. Six of seven patients had detectable HPV in papilloma and endolaryngeal swabs. Four were HPV type 6, and two were HPV type 11. The patient whose swab was negative for HPV was found to be biopsy negative for papilloma 3 weeks after a single laser excision which was performed 6 months prior to the endolaryngeal swab. HPV types 16, 18 and 31 were not found in any of the patients. No swabs from other sites in patients or family members were HPV positive despite the presence of adequate DNA in the swabbed material for successful amplification of beta-actin sequences. The absence of HPV (other than in the papilloma itself) in the upper aerodigestive tract of patients and caregivers is consistent with the absence of reported cases of horizontal transmission to siblings or other family members. The findings are also consistent with the conventional view that juvenile respiratory HPV is transmitted vertically from vaginal condylomas in the mother. 相似文献

OBJECTIVE: To assess the usefulness of cidofovir in treating recurrent respiratory papillomatosis in children. Cidofovir is an acyclic nucleoside phosphonate that has been reported to be effective in the treatment of respiratory papillomatosis in several small series of patients. METHODS: A prospective study was conducted in 11 children (mean, 2.1 years; range, 0.5-3 years at diagnosis) with recurrent respiratory papillomatosis who at the start of the study were requiring debridement of papillomas at least every 6 weeks. After microlaryngoscopy with powered microdebridement of papillomas patients received intralesional injection of cidofovir (5mg/ml). The severity of papillomatosis was rated at each visit using a standardized papilloma severity scoring system. The success of therapy was measured by the trend in the patient's papilloma severity scores before and after cidofovir therapy and by whether the frequency of operative interventions decreased in the period after treatment began. RESULTS: Three patients had impressive improvements in severity scores and a decrease in the frequency of required operative interventions after cidofovir, two patients had a partial response, and for six patients cidofovir was considered ineffective. CONCLUSIONS: Intralesional cidofovir did not decrease the severity or frequency of operative intervention for recurrent respiratory papillomas in the majority of children in this study. The drug did improve papillomatosis in the minority of patients without causing notable morbidity. A large multi-institutional controlled study is needed to better assess the efficacy of this treatment. 相似文献

Recurrent respiratory papillomatosis is a rare, but devastating, cause of airway lesions in children and adults. This disease is caused by human papilloma virus subtypes 6 and 11. At this time there are two vaccines in late stages of development seeking Food and Drug Administration (FDA) approval to prevent cervical cancer, which is also caused by human papilloma virus. One of these vaccines has been developed to stimulate immunity to the most common subtypes that cause cervical cancer but also includes those responsible for recurrent respiratory papillomatosis. With the possibility this could drastically reduce the incidence of RRP, the otolaryngology community should advocate for implementation of a vaccine program that provides effective prevention of HPV infection with subtypes 6 and 11. 相似文献

Identification of the type of human papilloma virus (HPV) was done by means of polymerase chain reaction in 40 children with juvenile respiratory papillomatosis (JRP). Adjuvant to surgery interferon treatment was carried out in 18 patients (study group) with severe JRP. The rest 22 patients (control group) with less severe papillomatosis received only surgical treatment. The majority of the patients from both the groups had the virus type 6/11 (72.2 and 77.3% for the study and control groups, respectively). The assessment of a relationship between HPV type and effectiveness of interferon treatment in the study group has shown that the share of patients with effective and uneffective interferon therapy in each category (by HPV type) was about the same, i.e. no correlation exists between HPV type and interferon therapy effectiveness. 相似文献

利用ISH方法以及免疫病理手段对不同型的LP组织的标本进行PCNA、P53检测,探讨不同型HPV与LP的发生发展的相关机制,以寻求有效的检测方法帮助临床对LP的预后进行评估。标本选自1994年1月~1995年12月间我院收治的LP共36例。ISH法HPV6b/11阳性率为75%,明显高于HPV16和/或HPV18的表达。10例喉鳞癌各有1例HPV16、18阳性,无HPV6b/11阳性。ABC法行P53检测,36例LP标本中仅1例恶变组织阳性表达Ⅱ级(2.8%);10例喉鳞癌中9例阳性表达(90.0%),其中Ⅱ级以上阳性表达6例(60.0%)。PCNA阳性表达27/36例(75%);其中JOP组与AOP组阳性率有显著差异(P<0.05)。本研究表明LP与HPV感染有极为密切的关系,认为HPV分型的检测在判断LP转归中有意义。PCNA阳性表达程度在预测LP肿瘤的活跃程度方面是一个很有意义的指标。P53蛋白表达在喉鳞癌与LP中有显著差异。 相似文献
