Application of transoral robotic surgery in treatment of oropharyngeal squamous cell carcinoma / 中华耳鼻咽喉头颈外科杂志

Objective: To evaluate the therapeutic and prognostic outcomes of transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OSCC). Methods: A retrospective study of 99 OSCC patients treated with TORS in Department of Head and Neck Surgery, Sun Yat-sen University Cancer Center between April 2017 and May 2021 was conducted. There were 84 males and 15 females, with an age range of 35-85 years. Patients' clinical characteristics, including clinical staging, HPV infection status, perioperative management and postoperative adjuvant treatment, were recorded. The overall survival (OS) and progression-free survival (PFS) were analyzed. The survival outcomes were analyzed with Kaplan-Meier method and Log-rank test. Results: The hospital stay of OSCC patients with TORS was (5.3±2.9) days and the average time of postoperative nasal feeding tube indwelling was (15.2±10.8) days. Among the 99 patients, 21 (21.2%) received tracheotomy and the average time of tracheotomy tube indwelling was (11.9±11.4) days. The two-year OS and PFS in patients with follow-up over two years were 94.0% and 87.7%, respectively and the three-year OS and PFS of patients with follow-up over three years were 94.0% and 78.9%, respectively. The two-year OS and PFS were respectively 97.4% and 88.9%, for patients with stages I-II and 86.8% and 88.9% for patients with stages III-IV. HPV-negative and HPV-positive patients had respectively two-year OS (100.0% vs. 91.5%) and PFS (88.9% vs. 87.2%). There was no significantly statistical difference in survival between patients with and without adjuvant radiotherapy after TORS (82.6% vs. 90.5%, HR=0.52, 95%CI: 0.12-2.23, P=0.400). Conclusions: TORS is more suitable for the treatment of patients with early (Ⅰ-Ⅱ) or HPV-positive oropharyngeal squamous cell carcinoma, and the recovery after TORS treatment is good.

Anal intraepithelial neoplasia associated with high-grade vulva injury (usual-type vulvar intraepithelial neoplasia): surgical treatment with cutaneous flap advancement

The aim of the present article is to report the case of a young patient with bowenoid papulosis who was a carrier of other sexually-transmitted infections (STIs), such as HIV and high-grade vulva lesion (usual-type vulvar intraepithelial neoplasia, VIN), and to demonstrate the strategy used to manage the case, as well as to discuss important issues regarding the standardization of intraepithelial lesions.

Papilomavírus humano: aspectos clínicos / Human papillomavirus: clinical aspects

A infecção pelo papilomavírus humano (HPV) é reconhecida como uma das principais causas de câncer relacionado à infecção em homens e mulheres. Embora a maioria das infecções pelo HPV seja assintomática e se resolva espontaneamente, a infecção persistente por tipos de HPV de alto risco pode levar a lesões precursoras e ao câncer. Em todo o mundo, a infecção pelo HPV causa até 4,5% (640.000 casos) de todos os casos novos de câncer mundial (8,6% mulheres; 0,9% homens), representando 29,5% de todos os cânceres relacionados com infecção. Os tipos de HPV de alto risco não são apenas responsáveis por praticamente todos os casos de câncer do colo do útero, mas também por uma fração dos cânceres de vulva, vagina, pênis, ânus e câncer de cabeça e pescoço. Além disso, o HPV também é a causa de verrugas anogenitais e papilomatose respiratória recorrente. Apesar da disponibilidade de múltiplas estratégias preventivas, o câncer relacionado ao HPV continua sendo uma das principais causas de morbimortalidade em muitas partes do mundo, principalmente nos países menos desenvolvidos.(AU)

ABSTRACTHuman papillomavirus (HPV) infection is recognized as one of the major causes of infection-related cancer in both men and women. Although most human papillomavirus (HPV) infections are asymptomatic and resolve spontaneously, persistent infection with high-risk HPV, may lead to precancerous lesions and cancer. Worldwide, HPV infection causes up to 4.5% (640,000 cases) of all new cancer cases worldwide (8.6% females; 0.9% males), representing 29.5% of all infection-related cancers. High-risk HPV types are not only responsible for virtually all cervical cancer cases but also for a fraction of cancers of the vulva, vagina, penis, anus, and head and neck cancers. Furthermore, HPV is also the cause of anogenital warts and recurrent respiratory papillomatosis. Despite the availability of multiple preventative strategies, HPV-related cancer remains a leading cause of morbimortality in many parts of the world, particularly in less developed countries.(AU)

Can quadrivalent human papillomavirus prophylactic vaccine be an effective alternative for the therapeutic management of genital warts? an exploratory study

ABSTRACT Objective: To evaluate the treatment effect of genital warts, we investigated the quadrivalent HPV vaccine injection compared with surgical excision. Materials and Methods: This prospective study included 26 patients (M:F = 24:2) who received HPV vaccine or surgical excision. After explanation of surgical excision or HPV vaccine, 16 patients underwent surgical excision and the others received HPV vaccine injections. Based on gross findings of genital warts, treatment outcomes were classified as complete response (no wart), partial response, and failed treatment. Results: Among enrolled patients, 42% (11 / 26) patients had recurrent genital warts. In vaccination group, complete response rates of genital wart were 60% following 3 times HPV vaccine. Partial response patients wanted to excise the genital lesions before the 3 times injection, because they worried about sexual transmission of disease to their sexual partners. One patient underwent surgical excision after 3 times injection. Excision sites included suprapubic lesions, but other sites including mid-urethra and glans showed complete response after injection. At a mean follow-up period of 8.42 ± 3.27 months, 10 patients (100%) who received HPV vaccine did not show recurrence. Conclusion: The response rates after HPV vaccine injection were 90% (complete and partial). Our results suggested that HPV vaccines could be effective in management of genital warts.

Use of the bilobed flap in the pubic region after tumoral lesion excision / Utilizacao do retalho bilobado na regiao pubiana apos exerese de lesao tumoral

Reconstruction of surgical defects in the pubic region is a challenge to any surgeon. Our goal was to demonstrate the use of the bilobed flap to reconstruct the pubic region skin after the excision of a recurrent HPV lesion, resistant to conventional treatments. In spite of its classical use in nasal reconstructions, the bilobed flap has applications in extranasal defects, with excellent functional and aesthetic results.

A reconstrução de defeitos cirúrgicos na região pubiana é um desafio para qualquer cirurgião. Objetivamos demonstrar a aplicação do retalho bilobado na reconstrução da região pubiana, após excisão de HPV recidivante aos tratamentos convencionais. Apesar da utilização clássica deste retalho ser na região nasal, aplicações em áreas distintas também se mostraram com excelentes resultados funcionais e estéticos.

Tratamento cirurgico e terapias adjuvantes na papilomatose respiratoria / Surgical treatment and adjuvant therapies of recurrent respiratory papillomatosis

Papilomatose respiratória recorrente ou papilomatose laríngea recorrente é uma doença da laringe, causada pelo papiloma vírus humano, caracterizada por lesões epiteliais verrucosas e, geralmente, recorrentes. Na literatura são descritos diversos tipos de tratamento, como cirurgia a frio, a laser e/ou uso de microdebridador, além das terapias adjuvantes; todas no sentindo de diminuir possíveis sequelas permanentes da doença. OBJETIVO: Realizar uma revisão de literatura a respeito desta doença com ênfase nas técnicas cirúrgicas e terapias adjuvantes mais utilizadas atualmente. MÉTODO: Utilizou-se a metodologia de revisão bibliográfica, por meio de levantamentos em base de dados eletrônicos de domínio público, entre 1992-2012, utilizando-se as palavras-chave: papiloma, infecções por papillomavírus, laringe, terapêutica, vacinas contra papillomavírus. RESULTADOS: Foram levantados 357 artigos, dos quais 49 foram usados como base para esta revisão. Os trabalhos científicos apontam para a redução de recidiva na maioria das terapêuticas adjuvantes. Entretanto, o levantamento demonstrou metodologias e amostras diferentes, o que não permitiu comparar os tipos de tratamento e de terapias adjuvantes. CONCLUSÃO: A escolha da técnica cirúrgica varia entre os autores, porém, há uma tendência atual ao uso do microdebridador. As terapias adjuvantes recentes, como cidofovir, vacina tetravalente contra o papiloma vírus humano e bevacizumab, necessitam de estudos mais amplos. .

Recurrent respiratory papillomatosis or recurrent laryngeal papillomatosis is a disease of the larynx caused by human papilloma virus, characterized by verrucous epithelial lesions and usually recurring. In the literature there are several types of treatment, such as surgery to cold, laser and/or use of microdebrider, as of adjuvant therapies; all possible to decrease the permanent sequelae of the disease. OBJECTIVE: To review the literature regarding this disease with emphasis on surgical techniques and adjuvant therapies used today. METHOD: We used the literature review, through surveys based electronic data in the public domain, to search for articles between 1992-2012, using keywords: papilloma, human pappiloma virus infection, larynx, therapeutic, papilloma virus vaccine. RESULTS: We surveyed 357 articles, of which 49 were used as the basis for this review. Scientific studies indicate a reduction of relapse in most adjuvant therapeutic presented. However, the survey showed different methodologies and samples, which did not allow to compare the types of treatment and adjuvant therapies. CONCLUSION: The choice of surgical technique varies among studies, but there is a trend to use the microdebrider. The newer adjuvant therapies, such as cidofovir, quadrivalent vaccine against human papilloma virus and bevacizumab, require further studies. .

Laryngeal sequelae of recurrent respiratory papillomatosis surgery in children

OBJECTIVE: To evaluate laryngeal sequelae from surgical treatment of recurrent respiratory papillomatosis in children, as well as associated risk factors. METHODS: Case-control study. Medical record data analysis of 50 children with recurrent respiratory papillomatosis, divided into two groups: with and without laryngeal sequelae. The group of patients with laryngeal sequelae was compared to those without sequelae in regard to the onset of disease, age at first surgery, number and frequency of surgeries, disease stage, and type of surgery (CO2 laser, cold forceps). RESULTS: 23 patients (46%) sustained laryngeal sequelae. The most frequent sequela was anterior commissure synechia (17 patients [34%]), followed by glottic stenosis (six patients [12%]). There was no statistically significant difference between groups with and without laryngeal sequelae regarding the disease onset (p = 0.93), age at first surgery (p = 0.68), number of surgeries (p = 0.22), annual frequency of surgery (p = 0.93), presence of papilloma in anterior (p = 0.430) or posterior commissure (p = 0.39), and type of surgery (p = 0.27). The Derkay anatomical score (a staging system that assesses the extent of the disease in the aerodigestive tract) was significantly higher in the laryngeal sequelae group (p = 0.04). CONCLUSION: Laryngeal sequelae are a frequent complication of recurrent respiratory papillomatosis surgical treatment in children, particularly anterior commissure synechiae and glottic stenosis. Advanced stages are associated with increased risk of laryngeal sequelae after surgery.

The descriptive review, from recurrent respiratory papillomatosis of the disease, an enigmatic / A revisão descritiva da papilomatose respiratória recorrente da doença, um enigmático

INTRODUCTION: The recurrent respiratory papillomatosis (RRP), which is caused by the human papilomavirus type 6 and 11, is the most common benign neoplasm in the larynx among infants and the second more frequent cause of the hoarseness in childhood. Is a enigmatic disease that can be devastating for those whom are affected. Is way misunderstood, and the investigation is still on matter. OBJECTIVE: This review had as objective provide a global vision and an update of what is recognized about the RRP and that is ahead of interns therapies. This surgical and adjuvant was performed through the research of database PubMed, MEDLINE, Cumulative index to nursing and health, Allied Literature and Cochrane. Eletronic library sought to use the headers of the subject "Recurrent Respiratory Papillomatosis", "Juvenile Laryngeal Papillomatosis", "Respiratory Papillomatosis", "Pediatric Laryngeal Obstruction" and "Airway Management". The obtained results were analyzed of relevance for the theme. DISCUSSION: The human papillomavirus (HPV) is a little DNA virus that contain. The recurrent respiratory papillomatosis can affect people of any age, with the younger patient identified in a day of age and the oldest with 84 years. The most common presentation is the supporter of the RRP, it is the hoarseness. The therapy has been repetitive and debulking. The objective is to erradicate the disease, without damaging the normal structures. None modality has proven effective in the eradication of RRP. CONCLUSION: Recurrent Respiratory Papillomatosis is a frustrating disease, capricious with the potential of the morbid consequences by the cause of involvement of the airway and the risks of malignant degeneration.

INTRODUÇÃO: A papilomatose respiratória recorrente (PRR), que é causado pelo papilomavírus humano tipos 6 e 11, é a neoplasia benigna mais comum da laringe entre as crianças ea segunda causa mais frequente de rouquidão na infância. É uma doença enigmática que pode ser devastadora para aqueles a quem ela afeta. É muito mal compreendido, e investigação continua na ativa assunto. OBJETIVO: Esta revisão teve por objectivo proporcionar uma visão global e uma atualização do que é conhecido sobre RRP e que está à frente de interms therapies.This cirúrgica e adjuvante foi realizada através de pesquisa das bases de dados PubMed, MEDLINE, Index cumulativa de Enfermagem e Saúde Allied Literatura e Cochrane biblioteca electrónica procurou usar os cabeçalhos de assunto ''papilomatose respiratória recorrente'', ''papilomatose laríngea juvenil'', ''papilomatose respiratória'', ''obstrução laríngea pediátrica'' e ''gestão das vias aéreas''. Os resultados obtidos foram analisados de relevância para o tema. DISCUSSÃO: O papilomavírus humano (HPV) é um pequeno vírus de DNA que contêm. A papilomatose respiratória recorrente pode afetar pessoas de qualquer idade, com o paciente mais jovem identificado em um dia de idade eo mais velho de 84 anos. A apresentação mais comum é o sustentáculo da PRR é hoarseness. The de terapia tem sido repetida debulking. O objetivo é erradicar a doença, sem danificar as estruturas normais. Nenhum única modalidade tem mostrado ser eficaz na erradicação da PRR. CONCLUSÃO: Papilomatose respiratória recorrente é uma doença frustrante caprichoso com o potencial para consequências mórbidas por causa de seu envolvimento das vias aéreas eo risco de degeneração maligna.

Importância da infecção anal pelo HPV em mulheres / Importance of Anal HPV Infection in women

O presente estudo visa realizar uma revisão da literatura em relação ao diagnóstico e tratamento das mulheres com infecção anal pelo HPV. A frequência do câncer anal, antes considerada baixa, tem apresentado elevação considerável nos últimos 30 anos, com aumento de 40% de incidência entre as mulheres. Já é conhecido que a infecção anal por subtipos específicos do HPV predispõe o indivíduo à neoplasia intraepitelial anal, que pode evoluir para o câncer anal, estabelecendo a relação causal entre o vírus e essa neoplasia, com patogenia de transformação maligna similar ao câncer do colo uterino. Nenhuma normatização em relação ao rastreamento das mesmas foi proposta até o momento, mas é estabelecido que, por se tratar de infecções geralmente assintomáticas, seriam necessários exames específicos para seu diagnóstico, como citologia oncótica, anuscopia e técnicas moleculares para a detecção de DNA. Atualmente, há procedimentos tópicos e invasivos ou ablativos para o tratamento dessas lesões. Diante da alta prevalência da infecção anal pelo HPV e do novo conceito de doença sexualmente transmissível para o câncer anal, torna-se necessário o desenvolvimento e aplicação de protocolos de rastreamento, garantindo diagnósticos e tratamentos precoces, com diminuição da morbimortalidade, aumento da sobrevida e melhora da qualidade de vida das pacientes.(AU)

The present study aims to review the literature regarding the diagnosis and treatment of women with anal HPV infection. Despite having been considered low, the frequency of anal cancer has shown an important increase in the last 30 years, with an increment incidence of 40% among women. It is known that anal infection by specific subtypes of HPV predisposes individuals to anal intraepithelial neoplasm, which may progress to anal cancer, establishing the causal relation between the virus and this cancer, with the pathogenesis of malignant transformation similar to cervical cancer. However, no standardization regarding their management has been proposed so far. Being generally asymptomatic, the majority of anal HPV infections would require specific tests such as smear cytology, anuscopy and molecular techniques for detection of DNA for diagnosis. Currently, there are local and invasive procedures or ablative treatment for such lesions. Given the high prevalence of anal HPV infection and the new concept of sexually transmitted disease for anal cancer, it is necessary to develop and implement protocols for screening, ensuring early diagnosis and treatment. Thus, with the decrease of morbidity and mortality, it will be possible to increase survival and improve quality of life of patients.(AU)

Carcinoma epidermoide en condilomatosis vulvoperineal gigante / Epidermoid carcinoma in giant vulvoperineal condilomatosis

La condilomatosis vulvoperineal es una entidad muy frecuente en mujeres en edad reproductiva; recomendándose realizar la tipificación del virus papiloma humano, dada la relación de algunos subtipos con el carcinoma epidermoide a nivel ginecológico. Se presenta el caso de una paciente femenina de 39 años que consultó por presentar una lesión exofítica, verrugosa que ocupa labios mayores y menores de la vulva, clítoris, introito vaginal y región perianal; de la cual se toma biopsia incisional reportando papilomatosis por virus papiloma humano, sin evidencia de atipias. Se lleva a quirófano realizando dermovulvectomía, cuya biopsia definitiva reportó carcinoma epidermoide invasor bien diferenciado, focal, con bordes resección libres; se completa con disección inguinal bilateral superficial y profunda sin evidencia de lesión metastásica ganglionar. Se realizó tipificación viral por reacción de cadena de polimerasa resultando VPH 16. A 20 meses de seguimiento, no hay evidencia clínica ni citológica de lesión recurrente. Es importante realizar la tipificación viral de estas lesiones por su relación con el carcinoma epidermoide de la vulva. Se realizó una revisión de la literatura.

The vulvoperineal condylomatosis it’s a very frequent disease in reproductive age young women; it’s recommended to realize the viral typification, because the relation between some human papillomavirus subtypes with gynaecology epidermoid cancer. We present the case of a 39 years old female patient who consulted to present a exofitic injury, warty that occupies the majora and minora labia of the vulva, clitoris, vaginal vestibule and perianal region; from which incisional biopsy was taken, reporting papilomatosis by human papillomavirus, without evidence of atypias. Patient went to operating room to receive a dermovulvectomy, whose definitive biopsy reported invasive epidermoid carcinoma well differentiated, focal, with free resection margins; it is completed with superficial and deep bilateral inguinal dissection without evidence of metastasic nodal involment. Viral tipificación by reaction of polymerase chain reaction was made being VPH 16. To 20 months of fall up, there are not clinical or cytological evidence of recurrent lesions. It is important to make the viral tipificación of these lesions by its relation with the epidermoid carcinoma of the vulva. A revision of literature was made.
