- Orthopedics: Musculoskeletal Tumors(2022) BAPTISTA, A. M.; REBOLLEDO, D. C. S.; JUNIOR, M. C. M. T.; CORREIA, L. F. M.; CAIERO, M. T.; TEIXEIRA, W. J.; NARAZAKI, D. K.; CAMARGO, A. F. de França; CAMARGO, O. P. deAmputation has historically been the first choice of treatment for patients with bone or soft tissue sarcomas of the extremities involving major blood vessels. However, recent advances in surgical technique have allowed limb-salvage surgery in a significant number of cases. Nowadays, most patients with malignant bone tumors can be treated with limb-salvage procedures whenever wide margins are possible. Surgical resection of bone and soft tissue tumors, with or without adjuvant radiation therapy, is effective in achieving local control, and limb-salvage procedures have been accepted because they achieve survival rates comparable to those of amputation allowing better quality of life. Along with other reconstructive techniques, vascular reconstruction might allow limb-sparing surgery and avoid amputation in patients with malignant tumors involving major vessels. Intraarterial embolization may as well serve as adjuvant therapy for major resection surgeries or therapeutic in some types of irresectable tumors. © Springer Nature Switzerland AG 2022.
- TUMORS OF THE PATELLA: THE EXPERIENCE OF INSTITUTE OF ORTHOPEDICS AND TRAUMATOLOGY AT UNIVERSITY OF SAO PAULO, BRAZIL(2016) BAPTISTA, Andre Mathias; SARGENTINI, Sylvio Cesar; ZUMARRAGA, Juan Pablo; CAMARGO, Andre Ferrari de Franca; CAMARGO, Olavo Pires deObjective: To obtain epidemiological data from the tumors of the patella diagnosed and treated at the Instituto de Ortopedia e Traumatologia do Hospital das Clinicas da Universidade de Sao Paulo (IOT-HC-FMUSP) between 1998 and 2015. Methods: Series of cases with retrospective evaluation of patients diagnosed with tumors located in the patella. The data was obtained from the records and patients' charts at the Department of Pathology of IOT-HC-FMUSP. Results: A total of 2220 medical records from patients with anatomopathological reports were included in the study. Only eight (0.3%) patients had patellar tumors. We found that six (75%) of these were benign, one (12.5%) was a pseudotumoral lesions and one (12.5%) was reported as malignant. Among benign tumors, the giant cell tumor (GCT) was the most frequently reported corresponding to 50% of the cases. Hemagioendothelioma was the only case of malignant tumor in this series. As for the pseudotumoral lesions, we found a brown tumor. Conclusion: From the data obtained retrospectively in a 17 year time frame, in a service that treats benign, malignant and pseudotumoral bone lesions, we conclude that our casuistry in patellar tumors is similar to that reported in scientific literature, where benign tumors are predominant in a 7: 1 ratio over malignant tumors, being a rare location of appearance, with the GCT as the most common diagnosis.
- GCT: WHAT HAPPENED AFTER 10 YEARS OF CURETTAGE AND CEMENT? RETROSPECTIVE STUDY OF 46 CASES(2014) BAPTISTA, Andre Mathias; CAMARGO, Andre Ferrari de Franca; CAIERO, Marcelo Tadeu; REBOLLEDO, Daniel Cesar Seguel; CORREIA, Luiz Filipe Marques; CAMARGO, Olavo Pires deObjective: To compare the functional outcome of patients with and without arthrosis, and to determine whether the development of arthrosis is related to the distance of the tumor from the subchondral bone. Methods: Forty six patients treated for Giant-cell tumor (GCT) between 1975 and 1999 met inclusion criteria. GCT was diagnosed by percutaneous biopsy and confirmed after resection, in all cases. Campanacci's and Kellgren's classification, the distance of the cement to the articular surface and MSTS score were obtained throughout the sample. Results: The distance of the cement to the sub-chondral bone was associated with greater risk of developing arthrosis, but there was no difference in MSTS scores between patients with or without arthrosis. Conclusion: We found that the distance from the cement to the subchondral bone has a prognostic value regarding future arthrosis, but it does not impact on the functional outcome.
