ABSTRACT

OBJETIVO Identificar la tasa de recurrencia de tumor de células gigantes (TCG) en pacientes tratados con curetaje y cementación con seguimiento mínimo de tres años. MATERIALES Y METODOS Cohorte retrospectiva y observacional de pacientes con diagnóstico de TCG en estadios 1 y 2 de Enneking tratados con curetaje intralesional y cementación entre 1981 y 2011. Se registraron edad, sexo, región anatómica, y tiempo de recurrencia. Se utilizó estadística descriptiva con medidas de tendencia central y medidas de dispersión (desviación estándar) para variables cuantitativas, y porcentajes para variables cualitativas. RESULTADOS Entre 1981 y 2011, se identificaron 375 casos de TCG, de los cuales 141 (37,6%) fueron tratados con este método. El seguimiento fue de 48 a 240 meses, y la edad, de 27 9 años; 45% de los pacientes eran mujeres, y 55%, varones, con una relación mujer:hombre de 1,2:1. El hueso más afectado fue la tibia (38%), seguida del fémur (32%), del húmero (16%), y del radio (10%). En 88,6%, la resección fue curetaje intralesional, y el resto, marginal. Hubo 15,7% de casos de TCG con fractura, y recidiva en 12,7%. DISCUSIÓN Se ha demostrado que este método de tratamiento reduce el riesgo de recurrencia por los efectos adyuvantes locales de la cementación acrílica. La recurrencia ocurre en los dos primeros años de seguimiento. Sin embargo, hay autores que respaldan que el margen quirúrgico es el único factor que influencia el riesgo de recurrencia local. La extensión extraósea del TCG no es contraindicación para curetaje intralesional y adyuvante con metilmetacrilato. CONCLUSIONES Reportamos tasa una de recurrencia similar a la de la literatura, siendo un recurso factible de reconstrucción de miembros


OBJETIVE To identify the recurrence rate of giant-cell tumor (GCT) in patients treated by curetage and adjuvant therapy with polymethil metacrylate with a minimum followup of 3 years. MATERIALS AND METHODS Observational and retrospective cohort with patients with diagnoses of Enneking stages 1 and 2 GCT treated through intralesional curetage and cementation between 1981 and 2011. Age, gender, anatomic location and relapse period were recorded. The data was analyzed with measures of central tendency and dispersion (standard deviation) for the quantitative variables, percentages for the qualitative variables. RESULTS Between 1981 and 2011 375 cases of GCT were identified, 141 (36.7%) of which were treated by this method. The follow-up ranged from 48 to 240 months, the age was of 27 9 years, 45% of the patients were female, and 55%, male, with a female: male ratio of about 1.2:1. The tibia was the most frequent affected bone (38%), followed by the femur (32%), the humerus (16%), and the radius (10%). The resection thecnique was intralesional curetage in about 88.6% of the cases, and marginal resection in the remaining cases. Pathologic fracture was present in approximately 15.7%, and recurrence occurred in approximately 12.7%. DISCUSSION We demonstrated that this treatment method decreases the risk of recurrence due to the local adjuvant effects of acrylic cementation. Recurrence events occur in the first two years after resection. However, some authors defend that the surgical margin is the only factor that influences the risk of local recurrence. The extraosseus extension of GCT is not a contraindication to perform intralesional curetage or to prescribe the adjuvant treatment with polymethyl metacrylate. CONCLUSIONS We reported a recurrence rate similar to that of the literature, and this is a feasible resource for limb reconstruction

ABSTRACT

This study aimed to ascertain the relationship between early diagnosis of giant-cell tumors (GCT) and their prognosis, by correlating the time of symptom onset with the staging of the injury (through the Campanacci classification at the time of diagnosis), and with the type of treatment. The secondary objective of the study was to outline the epidemiological profile of patients with GCT in the region where the data were gathered, and to compare them with data in the literature. METHODS: The authors present an evaluation on 61 patients diagnosed with bone GCT, with regard to the site of involvement, age, initial symptoms, time of symptom onset, classification and type of treatment, among patients attended between May 1994 and August 2009. RESULTS: The threshold indicated as the limit for Campanacci stage I tumors to be the commonest diagnosis, with a 98.2% chance that the treatment would be non-aggressive, was 2 months after symptom onset. This finding was statistically significant (p = 0.017). Every additional month increased the chance that a patient would be diagnosed with an advanced-stage tumor by 10.94%, in relation to the chances of having the other two stages of the tumor. CONCLUSION: The study result not only suggests that the alternative hypothesis that the earlier the diagnosis of GCT is, the less severe the lesion will be, has been confirmed; but also especially predicts the relationship between the time of symptom appearance and the severity of the tumor.


Presumir a relação entre o diagnóstico precoce do tumor de células gigantes (TCG) e o seu prognóstico, relacionar o tempo de surgimento dos sintomas com o estadiamento da lesão, por meio da classificação de Campanacci no momento do diagnóstico, e com tipo de tratamento. O objetivo secundário do estudo é traçar o perfil epidemiológico dos pacientes com TCG da região onde foram colhidos os dados e compará-lo com dados da literatura. MÉTODOS: Avaliação de 61 pacientes diagnosticados com tumor de células gigantes ósseo quanto ao local de acometimento, idade, sintomatologia inicial, tempo do surgimento dos sintomas, classificação e tipo de tratamento em pacientes atendidos entre maio de 1994 e agosto de 2009. RESULTADO: Aponta o marco de dois meses após o início da sintomatologia como data limite, quando seria mais comum o diagnóstico de tumor estágio I de Campanacci e com 98,2% de chance de ser tratado de modo não agressivo, dados com relevância estatística (p = 0,017). A cada aumento de um mês a chance de um paciente ser diagnosticado com tumor em estágio avançado é 10,94% maior do que em relação aos outros dois estágios do tumor. CONCLUSÃO: O resultado do estudo sugere não somente a confirmação da hipótese opcional de que quanto mais precoce o diagnóstico de TCG, menos grave é a lesão, mas, principalmente, prediz a relação do tempo de surgimento do sintoma com a gravidade do tumor.

ABSTRACT

BACKGROUND: 10% of > 55-year-old adults suffer some kind of non-neoplastic knee pain and 75% of the musculoskeletal neoplastic disease develops in the knee. OBJECTIVE: to identify clinical characteristics of knee pain in neoplastic knee pathology. METHODS: after appropriate authorization of the Local Committee of Investigation and under informed consent, we made a crosssectional and a risk analysis study. We included 160 patients who were seeking medical help due to knee pain. They answered a standardized questionnaire relating to the characteristics of their pain symptomatology. Data were integrated into two groups with knee pain; a) neoplasic (cases, n = 65), b) non-neoplasic (controls, n = 95) and analyzed (SPSS v.15™). We used homogeneity tests between groups (p > 0.05); inferential analysis (Student t test, χ(2)) and risk assessment (OR), p ≤ 0.05, (CI 95%), Statistical power was > 0.80. RESULTS: female gender predominated (55%); age was 40.3 ± 19.6 years. The most prevalent diagnoses were knee osteoarthritis 37% for non-neoplasic group; giant cell tumor 10% for benign neoplasic group and osteosarcoma 6.1% for neoplasic malignant group. Knee pain lasting < 4 months (OR 7.6; CI 95% 3.48-16.5) and severe intensity (OR 5.7; CI 95% 2.82-11.64), constant pain (OR 2.9; CI 95% 1.37-6.36), rapidly progressive fluctuation (OR 31; CI 95% 7.01-137) and nocturnal predominance (OR 7.72; CI 95% 3.2-18.5) were characteristics of neoplasic knee pain. CONCLUSIONS: the neoplasic knee pain was characterized for a rapid onset, severe and constant pain, progressive, fluctuation and predominantly by night-time.

ABSTRACT

A retrospective analysis of all bone tumors accessioned at a large referral center (Instituto Nacional de Rehabilitacion) in Mexico City between 2000 and 2005 is presented. A total of 6216 biopsies and surgical resection specimens were reviewed during this period, of which 566 corresponded to bone tumors. Benign bone tumors accounted for 71.6% of cases and malignant bone tumors for 28.4%. The tumors affected men in 53.7% of cases and women in 46.3% of cases, with an average age at presentation of 25 years. The femur was the most common location of the tumors (39.9%), followed by the tibia (17.7%) and humerus (11.8%). The commonest malignant bone tumors were osteosarcoma (46.6%) and chondrosarcoma (8.7%). Of malignant bone tumors, 18.6% corresponded to metastases of carcinomas from internal organs and 8.1% were multiple myeloma. The most common benign bone tumor was osteochondroma (43.7%) followed by giant cell tumor of bone (14.6%) and enchondroma (10.1%). The age distribution showed a peak in children and adolescents comprised predominantly of benign lesions and a second peak in young adults that corresponded to malignant bone tumors (principally osteosarcoma). Malignant bone tumors most often involved the femur, vertebra, and tibia. Our results parallel the findings previously reported in the world literature and show a similar distribution and epidemiology as in other developed and underdeveloped countries. Geographic location does not appear to represent a risk factor for any particular type of bone tumor and does not affect the age distribution, location, or histopathologic type of the lesions.

ABSTRACT

Se describen 56 pacientes con Tumor de Células Gigantes en Hueso, diagnosticados en el Instituto Nacional de Cancerología, durante 11 años. La edad de presentanción fue en promedio de 35.02 años. Con una relación de mujeres a hombres de 1.4 a 1. El síntoma más frecuente fue dolor y el signo más frecuente, la masa, La imagen radiológica en huesos largos es bastante caracteristica, siendo en la mayoría de los casos epifisiario, con una patrón destructivo del tipo geográfico y presencia de trabéculas en su interior. Los sitios anatómicos más frecuentemente comprometidos fueron el extremo superior de la tibia y el extremo inferior del fémur. En huesos planos se presentaron casos en la columna y en la pelvis. Aunque el patrón radiológico no es carcaterístico, es una lesión que se debe tener en cuenta como diagnóstico diferencial. Se presentaron 2 casos de TCG malignos

ABSTRACT

Se estudiaron de forma retrospectiva 107 casos (100%) de tumores óseos malignos, inscriptos en el Instituto Nacional de Oncología y Radiobiología (INOR) desde enero l964 hasta diciembre de l974 que comprendían 44 osteosarcomas (41%), 28 condrosarcomas (26,2%), 26 sarcomas de Ewing (24,3%), 6 tumores de células gigantes (5,6%) y 3 fibrosarcomas (2,8%) en los cuales se tuvieron en cuenta aspectos epidemiológicos, diagnósticos y terapéuticos, con el fin de conocer el comportamiento de los mismos, concluyéndose que: el 73% de los tumores óseos malignos se presenta entre la primera y la tercera décadas de la vida, pero la edad de máxima incidencia se encuentra entre los 10 a 19 años, con un 44,9%. Predominan en el sexo masculino y la raza blanca. En el 43% de los casos, la aparición del tumor se relacionó con un trauma local previo de intensidad variable. El 47% de nuestros pacientes tuvo síntomas por más de 6 meses antes de acudir a un centro médico asistencial y sólo el 4,7% buscó atención antes del mes de aparición de las mismas, destacándose el dolor, la impotencia funcional, el tumor, los cambios locales de temperatura y más raramente las fracturas patológicas, como los síntomas de presentación. El 75% de las lesiones se localizaron en los huesos largos: fémur (36,4%), tibia (16,8%) y húmero (10,3%) como los sitios más importantes. La diáfisis y la metáfisis, respectivamente, fueron las localizaciones principales de origen tumoral. El tratamiento de elección fue la cirugía a la demanda asociada con la radioterapia y a la quimioterapia pre o posoperatoria, en dependencia con el tamaño de la lesión, el tipo histológico y el estado físico y psíquico de los enfermos. La supervivencia actuarial quinquenal fue de 69%
