Squamous Cell Carcinoma Originating from Adult Laryngeal Papillomatosis: Case Report and Review of the Literature. Case Rep Otolaryngol 2018; 2018:4362162. [PMID: 30662782 PMCID: PMC6313995 DOI: 10.1155/2018/4362162] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 11/01/2018] [Accepted: 11/06/2018] [Indexed: 11/18/2022] Open
Abstract
Background The malignant transformation of laryngeal papillomatosis (LP) into squamous cell carcinoma (SCC) can occur in up to 4% of LP cases. The low-risk HPV types 6 and 11 are those that are most commonly related to LP; however, high-risk HPV types may be present. The present study reviews the literature on cases of malignant transformation of LP in adults and reports a clinical case. Case Report A 47-year-old male patient exhibiting hoarseness for 4 months presented an exophytic lesion in the right palatine tonsil and a digitiform-like lesion in the right vocal fold. The biopsy revealed a well-differentiated SCC in the vocal cord, which showed a transition zone with a squamous papillomatous lesion. By using the chromogenic in situ hybridization (CISH) test, both lesions showed a positive result for high-risk HPV types 16 and 18 and negative for low-risk HPV types 6 and 11. The final diagnosis was SCC arising from LP. The patient underwent surgical treatment. After 36 months of follow-up, no signs of recurrence were observed. Results The literature review revealed 25 cases of malignant transformation into SCC of LP with adult onset. Of these, only 9 cases were assessed by CISH and/or PCR for HPV identification, of which 7 were positive. The current study focuses on the eighth case, suggesting the involvement of the high-risk HPV types in its pathogenesis. Conclusions LP is considered a benign lesion with the potential for malignant transformation, which reinforces the need for its early diagnosis and the constant monitoring of patients with LP.

HPV Type 6 and 18 Coinfection in a Case of Adult-Onset Laryngeal Papillomatosis: Immunization with Gardasil. Case Rep Otolaryngol 2015; 2015:916023. [PMID: 26783482 PMCID: PMC4691470 DOI: 10.1155/2015/916023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2015] [Revised: 11/11/2015] [Accepted: 11/16/2015] [Indexed: 11/17/2022] Open
Abstract
Laryngeal papillomatosis (LP) is a rare human papillomavirus (HPV) related disease that often requires multiple surgical interventions and residual impairment of voice is almost inevitable. We report the case of a patient with adult onset recurrent LP, showing moderate dysplasia and coinfection with HPV types 6 and 18. The tetravalent HPV vaccine Gardasil was prescribed off label, with the aim of triggering an immunogenic response and consequently reducing the probability of further recurrences. The patient was followed for 9 months with no sign of relapse of his LP. The postexposure use of the anti-HPV vaccine could represent a promising therapeutic agent in established LP. Unfortunately, the potential efficacy of this new therapeutic option in this situation has been suggested only by isolated case reports. Further controlled studies, with a longer follow-up and a larger sample size, are needed to assess efficacy of Gardasil in LP.

Abstract
Laryngeal papillomatosis is the most common benign neoplasm of the larynx. Juvenile onset laryngeal papillomatosis tends to recur. In patients with adult onset laryngeal papillomatosis, laryngeal cancer rarely develops. This paper reports a clinical analysis of 60 patients with laryngeal papillomatosis who were treated at our clinic between January 1971 and September 2009. We analyzed the sex ratio, age at the onset of papilloma, type of developing papilloma (single or multiple type), site of developing papilloma, recurrence rate, and therapeutic modalities. Furthermore, the clinical characteristics of the patients with malignant transformation were examined. The patients were classified according to their age at the onset of the papilloma and the type of developing papilloma. The patients were grouped into a juvenile-onset group and an adult-onset group according to their age at the onset of the papilloma. They were also classified into single-type or multiple-type according to whether the initial papilloma appeared singly or multiply. The male to female sex ratios were 1.2 in the juvenile-onset group and 5.1 in the adult-onset group. Among the patients who developed papilloma at an age of under 10 years old, most of the juvenile cases had experienced onset by 4 years of age. Furthermore, the frequency of multiple-type papilloma was significantly higher in the juvenile-onset group, compared with the adult-onset group. The vocal fold was the most frequent site of the papilloma. The recurrence rate in the juvenile-onset group was significantly higher than that of the adult-onset group. A stratified analysis according to the type of papilloma occurrence, however, showed no significant difference in recurrences between the juvenile-onset and adult-onset groups. A stratified analysis according to the age at the onset of papilloma showed that the recurrence rate of multiple-type papilloma was significantly higher than that of single-type papilloma in the adult-onset group. Among multiple therapeutic modalities, vaporization by carbon dioxide laser was the most frequently used. Adjuvant therapy was performed in 6 cases who suffered from multiple relapses. The injection of interferon was performed in 5 cases, and the local injection of cidofovir was performed in 1 case. Malignant transformation of the papilloma was confirmed in 3 cases. The periods between the onset of papilloma and the malignant transformation were 40 years, 14 years, and 3 years. The present study indicates that patients with laryngeal papilloma developing at multiple sites have a significantly higher rate of relapse, even in the adult-onset group. There was no tendency in the period observed between the onset of papilloma and malignant transformation. From the standpoint of recurrence and malignant transformation, patients with papillomatosis should be carefully followed up for a long period of time.

Abstract
Laryngeal cancer is one of the most frequent types of head and neck cancer. The incidence is decreasing for men but still increasing for women. The incidence in Germany is about 5-7/100,000 persons/year for men and 0.6-0.8/100,000 persons/year for women. Due to the increased life expectancy, the average age of patients diagnosed with laryngeal cancer is increasing. Nevertheless, adequately prepared older patients treated by standard protocols can have the same survival and complication rates as younger patients. Tobacco and alcohol are still the primary risk factors responsible for disease in at least 80% of the patients. Despite the many new diagnostic tools, still more than half of the patients are diagnosed at an advanced tumor stage. Survival rates have not improved significantly in the last 10 years in Germany, and the average 5-year overall survival rate is about 60%. However, a decrease in the survival rate, as observed in the USA, cannot be confirmed for Germany.

Abstract
OBJECTIVES The study goal was to evaluate the efficacy of CO₂ laser surgery in the treatment of laryngeal papillomatosis. We analysed several parameters such as gender, average age, relapse rate and viral serotype. MATERIAL AND METHODS A total of 26 diagnosed patients were included in this retrospective descriptive review. All of them were treated with CO₂ laser for laryngeal papillomas between 1995 and 2010. RESULTS This pathology was more prevalent in males (65.5%), with a slight predominance of a single larynx localisation over multiple lesion locations. Human papillomavirus (HPV) DNA was detected in 75.8% of the cases; genotypes 6 and 11 prevailed. Of the patients in this review, 44.8% relapsed; the relapse average was 2-3 episodes per patient. A total of 20.7% of cases were in remission (no relapse in the last 2 months); 34.5%, clearing (no apparent relapse in the last 3 years); and 41.3% in the healing stage (without relapse in the last 5 years). There was only one case that showed malignancy. CONCLUSION Papillomatosis is characterised as a pathology with an unpredictable course and with a low probability of malignancy. CO₂ laser surgery has meant a revolution in symptomatic treatment, but there is presently no curative treatment.

HPV types causing juvenile recurrent laryngeal papillomatosis in South Africa. Int J Pediatr Otorhinolaryngol 2010; 74:255-9. [PMID: 20018386 DOI: 10.1016/j.ijporl.2009.11.016] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2009] [Revised: 11/20/2009] [Accepted: 11/20/2009] [Indexed: 11/21/2022]
Abstract
OBJECTIVES To identify human papillomavirus (HPV) types associated with juvenile onset recurrent laryngeal papillomatosis (RLP) in southern Africa, to determine if there is a correlation between HPV type and disease aggressiveness and to determine the diagnostic and prognostic value of rapid molecular techniques for detection and typing of HPV using laryngeal biopsies. METHODS Laryngeal biopsies from patients undergoing surgery for RLP were screened for HPV using conventional and real-time PCR techniques. Amplicons were sequenced to determine the HPV type involved. Clinical features were correlated with HPV type. RESULTS HPV was identified in papillomata from 18 out of 19 patients. Only HPV-6 and HPV-11 were identified, with no co-infections. There was 100% concordance between conventional and real-time PCR techniques. Patients with HPV-11 disease required more procedures and tended to have higher Derkay scores than those with HPV-6 disease. The HPV types identified in our patients were genetically similar to HPV types from geographically distinct regions. CONCLUSIONS RLP in our patient population appears to be exclusively due to HPV-6 or HPV-11. HPV-11 disease appears to be more aggressive than HPV-6 disease. Identification of the HPV types provides motivation for inclusion of vaccines against these types in vaccination programs to protect women against infection and subsequently reduce the incidence of RLP.

Abstract
Recurrent respiratory papillomatosis (RRP) is a rare but potentially severe disease caused by papillomavirus, most often types 6 and 11. The disease, which occurs in both juvenile and adult forms, is characterized by benign epithelial tumors of the airway that most frequently affect the larynx but can also spread along the entire aerodigestive tract. Recurrent respiratory papillomatosis is the most common benign neoplasm of the larynx in children and the second most frequent cause of childhood hoarseness. Standard treatment, which is palliative only, consists of surgical excision of papillomata to maintain airway patency and improve voice quality. Recurrence despite repeated surgical procedures is the rule. To date, incorporation of adjuvant treatments has not been reliably beneficial in altering the disease course. Several case series have described promising results with cidofovir, a cytosine nucleoside analog with antiviral activity. To evaluate the data available on the safety and efficacy of cidofovir for the treatment of RRP, we conducted a MEDLINE search for all case reports or series from January 1966-August 2004 describing cidofovir therapy in either adults or children with RRP. The bibliographies of qualifying articles were also searched for relevant references. In both adults and children with mild-to-severe RRP, intralesional administration of cidofovir directly into the site of papillomata was associated with partial-to-complete regression of papillomata, improvement in voice quality and airway status, and decreased need for surgery. Wide variation in intralesional cidofovir dose (2-57 mg), frequency (every 2-8 wks), and duration (4 mo-4 yrs) was found. Successful outcomes have also been reported with intravenous cidofovir, but data are limited to three case reports. Rash, headache, and precordialgia were the only adverse effects reported with intralesional cidofovir. Nephrotoxicity and neutropenia secondary to either intralesional or intravenous cidofovir were not observed. Long-term risks associated with intralesional administration remain to be seen. Further studies are necessary to determine the most appropriate dose, frequency, and duration of therapy, and to fully characterize the safety profile profile of cidofovir when given intralesionally.

Abstract
OBJECTIVE: We sought to determine the efficacy of intralesional injection of cidofovir in improving resolution of recurrent respiratory papillomatosis (RRP).
STUDY DESIGN AND SETTING: We conducted a prospective, observational trial at an academic tertiary children's hospital.
RESULTS: Four children with RRP requiring more than 6 surgical excisions per year were treated with intralesional cidofovir. Cidofovir (5 mg/mL) was injected into airway sites where papillomas had just been excised using sharp technique. Each patient had 6 treatments performed 6 to 8 weeks apart. Biopsies confirmed benign papilloma lesions in all cases. During treatment with intralesional cidofovir there was diminished growth of the papillomas in each patient. Once cidofovir treatment was stopped, the rate of regrowth and frequency of surgical excision returned to pretreatment levels in 3 of the 4 patients.
CONCLUSIONS: Intralesional cidofovir may provide benefit in reducing the rate of RRP growth while under treatment, but RRP severity returned to pretreatment levels once cidofovir treatment was stopped using this treatment program.

Abstract
Human papillomaviruses (HPVs) are aetiological agents of human malignancies, most notably cervical cancers. The life-cycles of HPVs are dependent on epithelial differentiation, and this has impeded many basic studies of HPV biology. The organotypic (raft) culture system supports epithelial differentiation such that infectious virions are synthesized in raft tissues from epithelial cells that replicate extrachromosomal HPV genomes. The CIN-612 9E cell line maintains episomal copies of HPV type 31b (HPV31b), an HPV type associated with cervical cancers. Many previous studies, including our own, have focused on characterizing the later stages of the HPV31b life-cycle in CIN-612 9E raft tissues. In this study, we have used the raft system to generate large numbers of HPV31b viral DNA (vDNA)-containing particles. We found a biologically contained homogenization system to be efficient at virion extraction from raft epithelial tissues. We also determined that vDNA-containing particles could be directly quantified from density-gradient fractions. Using an RT-PCR assay, the presence of newly synthesized, spliced HPV31b transcripts was detected following HPV31b infection of the immortalized HaCaT epithelial cell line. Spliced E6 and E1( wedge )E4 RNAs were detected using a single round of RT-PCR from cells infected with a dose as low as 1.0 vDNA-containing particle per cell. Spliced E1*I,E2 transcripts were found in cells infected with an HPV31b dose as low as 10 vDNA-containing particles per cell. Infectivity was blocked by HPV31 antiserum, but was not affected by DNase I. This work lays a foundation for a detailed analysis of the early events in HPV infection.

Abstract
OBJECTIVE The purpose of this pilot study was to determine the frequency of human papillomavirus (HPV) in the oral cavities of children and adolescents and to identify potential risk factors for HPV infection. STUDY DESIGN Sociodemographic information was obtained on 268 healthy infants, children, and adolescents who were < or = 20 years old. Oral squamous cells were collected from swabs with young children and from oral saline solution rinses with older children and adolescents. Extracted DNA was evaluated for HPV by polymerase chain reaction, dot blot hybridization, and DNA sequencing. Factors associated with the presence of HPV were tested by using chi(2), Fisher's exact test, and logistic regression tests. RESULTS HPV was detected in 6.0% of the participants. HPV frequency among young children (<7 years old) was 8.7% (11/127), and among adolescents (13-20 years old) it was 5.2% (5/97). HPV was not detected in children aged 7 to 12 years old (0/44). Fifty-four percent (6/11) of HPV-positive children were 1 year of age or less; 3 of the HPV-positive children (<7 years old) were delivered by cesarean section. No statistically significant association was found between the detection of HPV in the oral cavity and method of delivery or gender; parent's race, education, HPV-related conditions, smoking history, or number of sex partners; or adolescent's smoking history or history of sexual activity. CONCLUSIONS This study suggests that HPV is present in the oral cavity primarily in children 2 years old and younger and in adolescents 13 years and older. Cesarean delivery was not protective against oral HPV infection; in fact, half of the HPV-positive infants were born by cesarean delivery.

Abstract
Squamous papillomas of the lung are an uncommon feature of recurrent respiratory papillomatosis, occurring in fewer than 1% of cases. We describe a 23-year-old patient with pulmonary papillomas who developed a fatal squamous cell carcinoma of the lung. PCR-based human papillomavirus (HPV) typing showed the presence of HPV 11 DNA in both benign papillomas and invasive carcinoma. A review of the literature reveals four reports of malignant transformation of juvenile-onset recurrent respiratory papillomatosis in which HPV typing was performed. Similar clinical features are noted in all of the reports; specifically, each case has arisen in a young adult man with a history of papillomatosis since childhood. In each of the cases, HPV 11 was identified in association with the squamous cell carcinoma. Although HPV 11 is uncommonly associated with the development of invasive carcinoma at other sites, these findings suggest that it is correlated with malignant transformation in the setting of juvenile-onset recurrent respiratory papillomatosis.
