ABSTRACT

Objective: To present the epidemiological profile of bone and soft tissue tumors that affect the elbow region treated at an oncology referral center in Brazil. Methods: Retrospective observational case series study to evaluate the results of elbow cancer undergoing clinical and/or surgical treatment with the first visit from 1990 to 2020. The dependent variables were benign bone tumor, malignant bone tumor, benign soft tissue tumor, malignant soft tissue tumor. Independent variables were sex, age; presence of symptoms (pain/increase in local volume/fracture); diagnosis; treatment and recurrence. Results: In total, 37 patients were included, 51.35% of whom were female, with a mean age at diagnosis of 33.5 years. Soft tissue neoplasms correspond to 51% of cases against 49% of bone tumors. Among the symptoms, the general prevalence of pain was 56.75%, the general increase in local volume occurred in 54.04% of the patients and the presence of fractures in 13.43%. Surgical treatment occurred in 75.67% of cases and recurrence in 16.21% of cases. Conclusion: The tumors that affect the elbow in our series correspond mostly to benign tumors, involving bone or soft tissues, with a higher occurrence in young adult patients. Level of Evidence IV, Case Series.

ABSTRACT

Objective: Characterizing ankle tumors, presenting the epidemiological profile of these lesions. Methods: Retrospective observational case series study to evaluate the results of clinical and/or surgical treatments of patients with ankle tumors whose first visit occurred from 1990 to 2020. The dependent variables were: benign bone tumor, malignant bone tumor, benign soft tissue tumor, malignant soft tissue tumor, and infection. The independent variables were: sex, age; presence of symptoms (pain/local volume increase/fracture), duration of symptoms until treatment, diagnosis, treatment, and recurrence. Results: In total, 70 patients were included-58.5% were women, with a mean age at the time of diagnosis of 21.66 years. Among all cases, 76% were bone tumor, 14% were soft tissue tumor, and 10% were infection. The mean age at the time of diagnosis was 21.7 ± 2.29 years. The overall prevalence of pain was 77.1%. In total, 55.6% patients had a general local volume increase 13.4% had fractures. The mean time from symptoms to treatment was 17.4 ± 4.61 months and the mean diagnosis time was 10.13 ± 0.86 months. Of all cases, 73.44% underwent surgical treatment and 22.64% had recurrence. Conclusion: In this series, ankle tumors corresponded mainly to bone tumors. Benign tumors were the most prevalent type of tumor and the highest occurrence was among young people. Level of Evidence IV, Case Series.

ABSTRACT

Objective: Evaluate risk factors related to clinical evolution and dedifferentiation of parosteal (juxtacortical) osteosarcoma to high-grade osteosarcoma. Methods: Retrospective cohort study performed over a period of 25 years, using data from medical records of patients diagnosed with parosteal osteosarcoma. The data were submitted to statistical analysis by Fisher's exact test and Student's t-test. Results: Of the 326 patients treated for osteosarcoma, we identified 17 patients diagnosed with parosteal osteosarcoma. Of these, 4 (23.5%) were not actually diagnosed with parosteal osteosarcoma and 4 did not have the minimum data required for analysis, being excluded from the study. Of the 9 patients studied, we observed that 3 (33.3%) evolved with tumor dedifferentiation to high-grade osteosarcoma. Moreover, 2 (66.7%) had local recurrence and 2 (66.7%) metastases. Conclusion: Age, sex, and the tumor size were not directly related to the dedifferentiation from parosteal osteosarcoma to high-grade osteosarcoma. The most aggressive clinical evolution - presence of local recurrences and metastasis - in parosteal osteosarcoma occurred in tumors with dedifferentiation, however, we cannot associate each other as cause and effect, but as related factors. Level of Evidence IV, Case Series.


Objetivo: Avaliar fatores de risco relacionados à evolução clínica e à desdiferenciação do osteossarcoma justacortical (parosteal, paraosteal) em osteossarcoma de alto grau. Métodos: Estudo de coorte retrospectiva realizado num período de 25 anos. Foram utilizados dados de prontuários de pacientes com diagnóstico de osteossarcoma parosteal que, em seguida, foram submetidos à análise estatística pelo Teste Exato de Fisher e pelo Teste t de Student. Resultados: Foram tratados 326 pacientes com diagnóstico de osteossarcoma, dos quais 17 (5,21%) receberam diagnóstico de osteossarcoma parosteal, 4 (1,22%) foram diagnosticados com osteossarcoma convencional e 4 (1,22%) não tinham dados mínimos necessários para análise, sendo excluídos do estudo. Dos 9 (2,76%) pacientes estudados, 3 (0,92%) evoluíram com desdiferenciação do tumor para osteossarcoma de alto grau. Dois (0,84%) pacientes apresentaram recidiva local e 2 (0,84%%) apresentaram metástases. Conclusão: Os fatores idade, sexo e volume do tumor não estão diretamente relacionados com a desdiferenciação do osteossarcoma parosteal para osteossarcoma de alto grau. Apesar de a evolução clínica mais agressiva - presença de recidivas locais e metástase - no osteossarcoma parosteal ter ocorrido nos tumores com desdiferenciação, não é possível estabelecer uma relação de causa e efeito, apenas considerá-las como fatores relacionados. Nível de Evidência IV, Série de Casos.

ABSTRACT

Objectives To identify the main risk factors related to poor outcomes after the treatment for periprosthetic infection. Materials and Methods Medical records from 109 patients who underwent non-conventional endoprosthesis surgeries (primary and revision procedures) from January 1, 2007, to December 31, 2018, were retrospectively evaluated. In total, 15 patients diagnosed with periprosthetic infection were eligible to participate in the study. Variables including gender, age at diagnosis, affected bone, surgery duration, white blood cell (WBC) count before endoprosthesis placement, urinary tract infection during the first postoperative year, and time elapsed from endoprosthesis placement to infection diagnosis were related to outcomes using the Fisher exact test (for the bicategorical variables) or analysis of variance (ANOVA, for the tricategorical variables). The mean times from diagnosis to final outcome were compared using the Student t -test. Results These risk factors did not show a statistically significant correlation with the outcomes. The data revealed a trend towards a difference between the mean time for the onset of infection and the final outcome. Due to the limited sample, we believe that studies with larger cohorts can prove this trend. Conclusion We identified that the time from endoprosthesis placement to the onset of the symptoms of infection tends to be related to the outcome and evolution of the patient evolution during the treatment for periprosthetic infection. Although apparently correlated, other associated factors were not statistically linked to poor treatment outcomes.

ABSTRACT

ABSTRACT Objective: Describe the epidemiological profile of patients with primary or secondary neoplastic lesions in the pelvis who required a surgical procedure such as hemipelvectomy. Methods: This study retrospectively evaluated 69 patients located in the database of a São Paulo educational institution, subject to surgical hemipelvectomy treatment between January 1990 and December 2013. All patients had previous diagnosis of bone tumor (primary or metastatic) in the pelvis (ilium, ischium, pubis, and/or sacrum). Results: Analyzing the data obtained in this study, it was observed that these are partly similar to those found in the literature, with primary bone malignancies as the main diagnosis; general injuries affecting the pelvic area I (pelvic bone) and its most frequent complication, infection. The differences are mainly due to rarity of the bone tumors evaluated in this study, and the type of surgical procedure in question, which is even more unusual. Conclusion: Building a picture that conveys the reality of each diagnosis and that indicates which characteristics of these patients would better resemble an absolute or relative indication for the realization of hemipelvectomy is harder by the rarity of these cases.


RESUMO Objetivo: Traçar o perfil epidemiológico dos pacientes com lesões neoplásicas na pelve, primárias ou secundárias, para as quais foi necessário procedimento cirúrgico do tipo hemipelvectomia. Métodos: Foram avaliados, retrospectivamente, 69 pacientes localizados no banco de dados de uma instituição de ensino de São Paulo, submetidos a tratamento cirúrgico tipo hemipelvectomia entre janeiro de 1990 e dezembro de 2013. Todos os pacientes apresentavam diagnóstico prévio de tumor ósseo (primário ou metastático) na pelve (ílio, ísquio, púbis e/ou sacro). Resultados: Ao analisar os dados obtidos no presente estudo, observou-se que esses são em parte semelhantes aos encontrados na literatura mundial, apresentam como principal diagnóstico as neoplasias malignas ósseas primárias. Em geral, as lesões acometeram a zona I pélvica (osso ilíaco) e a complicação mais frequentemente observada foi a infecção. As diferenças encontradas são devidas principalmente à raridade dos tumores ósseos avaliados nesses estudos e ao tipo de procedimento cirúrgico em questão, esses ainda mais incomuns. Conclusão: Construir um panorama que transmita a realidade de cada diagnóstico e indique quais as características que esses pacientes apresentam que mais se aproximariam como indicações relativas ou absolutas para o procedimento de hemipelvectomia encontra na raridade desses casos o seu maior obstáculo.

ABSTRACT

BACKGROUND: The aim of the present study was to conduct a cross-cultural adaptation (with translation into Brazilian Portuguese) and validation of the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire-Bone Metastases-22 (EORTC QLQ-BM22). METHODS: Ninety-five bone metastasis patients (31 men and 64 women, mean age 58.36±8.90 years) took part in the investigation. The translation guide of the EORTC was used to translate from English into Brazilian Portuguese and adapt the instrument culturally. The reliability and the face, content and construct validities were tested. RESULTS: Internal consistency was estimated using Cronbach's alpha for the total score, pain and functional subscales of the EORTC QLQ-BM22 (0.93, 0.86, 0.90). Reliability was analyzed by Pearson's correlation and intraclass correlation coefficients (ICCs). The correlations were higher than the recommended value of 0.75, which indicated good test-retest reliability. Construct validity was demonstrated by correlation with the questionnaire medical outcome study questionnaire 36-Item Short Form Survey (SF-36). It showed significant correlation between the fields of QLQ-BM22 and the SF-36 (P≤0.001). CONCLUSIONS: The EORTC QLQ-BM22 was translated into Brazilian Portuguese, was culturally adapted and was proven to be reliable, with face, content and construct validity.

ABSTRACT

OBJECTIVE: To outline the epidemiological profile and prognosis for Ewing's sarcoma in the Brazilian population. MATERIAL AND METHODS: The medical records of 64 patients with intraosseous Ewing's sarcoma who were treated at the Pediatric Oncology Institute, IOP-GRAACC-Unifesp, between 1995 and 2010, were retrospectively evaluated. RESULTS: The statistical analysis on the data obtained did not correlate factors such as sex, trauma, pathological fracture and time taken for case diagnosis with the treatment outcome. Factors such as initial metastasis, lung metastasis, tumor site, age, recurrence and type of surgery showed results corroborating what has been established in the literature. CONCLUSION: The prognosis in cases of Ewing's sarcoma was mainly influenced by the presence of metastases at the time of diagnosis.

ABSTRACT

OBJETIVO: Traçar o perfil epidemiológico e o prognóstico do sarcoma de Ewing na população brasileira. Material e MÉTODO: Foram avaliados, retrospectivamente, os prontuários de 64 pacientes tratados, com sarcoma de Ewing intraósseo, no Instituto de Oncologia Pediátrica, IOP-GRAACC-Unifesp, no período de 1995 a 2010. RESULTADOS: A análise estatística dos dados obtidos não correlacionou fatores como sexo, trauma, fratura patológica e tempo ao diagnóstico com o desfecho do tratamento. Fatores como metástase inicial, metástase pulmonar, local do tumor, idade, recidiva e tipo de cirurgia indicam resultados que corroboram a literatura consagrada. CONCLUSÃO: O prognóstico no sarcoma de Ewing foi influenciado principalmente pela presença de metástase ao diagnóstico.

Factors such as initial metastasis, lung metastasis, tumor site, age, recurrence and type of surgery showed results corroborating what has been established in the literature. CONCLUSION: The prognosis in cases of Ewing's sarcoma was mainly influenced by the presence of metastases at the time of diagnosis.
