Assessment of quality of life in patients with advanced oral cancer who underwent mandibulectomy with or without bone reconstruction

INTRODUCTION Malignant neoplasms of the head and neck, due to its anatomical location, can cause significant alterations in vital functions related to feeding, communication and social interaction of the affected patients. Objective To analyze the quality of life of patients with advanced malignant neoplasms of the oral cavity and submitted to radical operations with curative intent. Material and methods 47 patients with oral cavity squamous cell carcinoma (SCC), in stages III and IV, underwent surgical treatment with segmental mandibulectomy and complementary radiotherapy. The patients were submitted to the quality of life questionnaires after a minimum time of six months after the surgical treatment. Results Of the 183 patients, only 47 (25.7%) were able to answer the questionnaire and were included as the sample of the study. The majority of patients selected were male (39; 82.9%). The mean age was 64.4 years. The majority of the patients presented clinical stage IV (83%) and were submitted to adjuvant radiotherapy (95.4%). The mean score obtained after the questionnaires were applied was 64.6. The worst scores were found in swallowing and chewing. Conclusion There were no statistically significant differences in the domains of quality of life between the two groups studied (with bone reconstruction versus no bone reconstruction). Patients interviewed 2 years or more after treatment presented higher scores (p = 0.02).

RESUMO INTRODUÇÃO As neoplasias malignas de cabeça e pescoço, pela própria localização anatômica, podem acarretar alterações significativas em funções vitais relacionadas à alimentação, comunicação e interação social dos indivíduos afetados. OBJETIVO Analisar a qualidade de vida dos pacientes com neoplasias malignas avançadas de cavidade oral, submetidos a operações radicais com intenção curativa. MATERIAL E MÉTODOS 47 pacientes portadores de carcinoma espinocelular de cavidade oral, em estádios III e IV, foram submetidos ao tratamento cirúrgico com mandibulectomia segmentar e radioterapia complementar. Os pacientes foram submetidos ao teste de qualidade de vida após o tempo mínimo de seis meses do tratamento cirúrgico. RESULTADOS Dos 183 pacientes, com apenas 47 (25,7%) foi possível a realização da entrevista, compondo estes a amostra para o estudo. A maioria dos pacientes do grupo selecionado era do sexo masculino, total de 39 homens (82,9%). A idade média foi de 64,4 anos. A maioria dos pacientes apresentava estadiamento clínico IV (83%), sendo submetidos à radioterapia adjuvante (95,4%). A média do escore obtido após a avaliação dos questionários foi de 64,6. Os piores escores foram encontrados nos quesitos deglutição e mastigação. CONCLUSÃO Não houve diferenças estatisticamente significativas nos domínios de qualidade de vida entre os dois grupos estudados (com reconstrução óssea versus sem reconstrução óssea). Pacientes entrevistados dois anos ou mais após o tratamento apresentaram escores superiores (p=0,02).

Post-operative hemimaxillectomy rehabilitation using prostheses supported by zygoma implants and remaining natural teeth

OBJECTIVES: This study aimed to evaluate the stability of prostheses supported by zygoma implants and remaining teeth for subjects who had undergone hemi-maxillectomy. METHODS: Ten patients were included in the study. Oral rehabilitation was performed using a temporary prosthesis that was supported by remaining teeth for the first three months. Then, a zygoma implant was placed to provide support for a final prosthesis in addition to the remaining teeth. Each prosthesis was tailor-made according to biomechanical three-dimensional finite element analysis results. The patients were assessed using the prosthesis functioning scale of the Memorial Sloan-Kettering Cancer Center. In addition, retention and bite force were recorded for both the temporary prosthesis and the final prosthesis. RESULTS: The mean bite force of the prosthetic first molar was increased to 69.2 N. The mean retentive force increased to 13.5 N after zygoma implant insertion. The bite force on the prosthetic first molar was improved to 229.3 N. CONCLUSION: Bite force increased significantly with the support of a zygoma implant. The use of zygoma implants in the restoration of maxillary defects improved functional outcome and patient satisfaction.

Avaliação da qualidade de vida em pacientes com tumores avançados de cavidade oral submetidos a cirurgias de grande porte / Quality of life avaliation of pacientes with advanced tumors of oral cavity undergoing radical operations

Desde os primórdios da Medicina, a grande preocupação do profissional era ser humanista, com conhecimento cultural, sociológico, familiar, psicológico e espiritual do seu paciente. Durante a primeira metade do século XX, houve uma verdadeira explosão de novas técnicas operatórias e de evoluções no campo tecnológico, principalmente durante e logo após as duas grandes guerras mundiais. Novas especialidades, dentre essas a Cancerologia e suas subdivisões, iniciaram técnicas próprias de tratamento cirúrgico. Desde então, os tratamentos impulsionaram a realização de novos métodos de reconstrução dos defeitos produzidos pelas cirurgias, cada vez mais invasivas e mutiladoras. Portanto, além do diagnóstico e tratamento das enfermidades, começou a existir a preocupação com o resultado destes, como o tipo de contribuição e resultados funcionais para o paciente. Nas últimas décadas, houve a necessidade de avaliar a Qualidade de Vida (QV) destes pacientes frente aos tratamentos realizados. As neoplasias malignas de cabeça e pescoço, pela própria localização anatômica, podem acarretar alterações significativas em funções vitais relacionadas à alimentação, comunicação e interação social dos indivíduos afetados. Objetivo: Avaliar a qualidade de vida dos pacientes com neoplasias malignas avançadas de cavidade oral submetidos a operações radicais com intenção curativa, comparando um grupo de pacientes submetidos à reconstrução funcional de mandíbula com um grupo de pacientes nos quais esta reconstrução não foi efetuada. Material e métodos: 47 pacientes matriculados na Seção de Cirurgia de Cabeça e Pescoço do Hospital do Câncer (HCI-INCa), portadores de carcinoma espinocelular (CEC) de cavidade oral, em estádios III e IV, foram submetidos ao tratamento cirúrgico com mandibulectomia segmentar e radioterapia complementar. Todos foram submetidos ao teste de Qualidade de Vida após o tempo mínimo de seis meses do tratamento cirúrgico. A maioria tinha como sitio anatômico da...

Since the beginning of Medicine, the major concern of the professional was to be humanist, having cultural, sociological, family-related, psychological and spiritual knowledge of his patient. During the first half of the twentieth century there was an explosion of new surgical techniques and developments in the technological field, especially during and after the two world wars. New specialties, among these the Oncology and their subdivisions initiated proper techniques of surgical treatment. Since then the treatments have boosted the implementation of new methods of reconstruction of defects produced by surgery, increasingly invasive and mutilating, therefore, in addition to the diagnosis and treatment of diseases, came into being the concern about the outcome of these, such as the type of contribution and functional results for the patient. Over the last decades there was a need to assess the Quality of Life (QL) of these patients compared to the treatments performed. Malignant neoplasms of the head and neck, by their own anatomical location, may entail significant changes in vital functions related to feeding, communication and social interaction of the affected individuals. Objective: Assessing the quality of life of patients with advanced malignant neoplasms of the oral cavity undergoing radical operations with curative interaction, comparing a group of patients undergoing functional reconstruction of the jaw with a group of patients in whom this reconstruction was not performed. Material and methods: A total of 47 patients enrolled in the Head and Neck Surgery Section of the Cancer Hospital (HCI-INCA). Carriers of squamous cell carcinoma (SCC/CEC) of the oral cavity, in stages III and IV., were submitted to surgical treatment with segmental mandibulectomy and complementary radiotherapy. All were submitted to the Quality of Life test after a minimum period of six months from the surgery. Most had the anatomical site of primary buccal...
