- Complete response to alectinib following crizotinib in an ALK-positive tumor with CNS involvement(2021) XAVIER, Camila B.; CANEDO, Felipe S. N. A.; LIMA, Fabiola A. S.; MELO, Raissa R.; LIMA, Luiz Guilherme C. A.; MARIN, Jose Flavio G.; SOUZA, Ciro E.; FEHER, OlavoInflammatory myofibroblastic tumor (IMT) is a rare entity that affects mostly children and young adults. The lungs are the most frequent primary site. When feasible, surgical resection is the standard of care and it is associated with long-term survival benefit. Metastatic disease is rare, and central nervous system involvement is very infrequent. There is paucity of data regarding systemic treatment of recurrent or metastatic disease but most IMTs present with ALK rearrangements, becoming potential targets to ALK inhibition. Diagnosis of ALK rearrangements by FISH or RT-PCR is standard and discordant results from immunohistochemistry are rare. Crizotinib is considered the standard therapy in ALK-positive cases. Data supporting the use of other ALK inhibitors are scant and derived only from case reports. We report a case of a patient harboring an ALK-positive by IHC, FISH-negative IMT, that initially responded well to crizotinib but progressed in the CNS, presenting a complete CNS response with second-generation ALK inhibitor alectinib.

- Neoadjuvant stereotactic ablative radiotherapy (SABR) for soft tissue sarcomas of the extremities(2021) LEITE, Elton Trigo Teixeira; MUNHOZ, Rodrigo Ramella; CAMARGO, Veridiana Pires de; LIMA, Luiz Guilherme Cernaglia Aureliano de; REBOLLEDO, Daniel Cesar Seguel; MAISTRO, Carlos Eduardo Bravin; BUSNARDO, Fabio de Freitas; FERREIRA, Fabio de Oliveira; SALVAJOLI, Joao Victor; CARVALHO, Heloisa de AndradeBackground: Soft tissue sarcomas (STS) comprise a diverse group of mesenchymal malignancies that require multidisciplinary care. Although surgery remains the primary form of treatment for those with localized disease, radiation therapy (RT) is often incorporated either in the neo-or adjuvant setting. Given the development of modern RT techniques and alternative dosing schedules, stereotactic ablative radiotherapy (SABR) has emerged as a promising technique. However, the current role of SABR in the treatment of STS of the extremities remains uncertain. Methods and Materials: This was a single-center, prospective, single-arm phase II trial. Patients with localized STS who were candidates for limb-preservation surgery were included. Experimental treatment consisted of SABR with 40 Gy in 5 fractions, administered on alternate days, followed by surgery after a minimum interval of 4 weeks. The primary outcome was the rate of wound complication. Secondary outcomes included 2-year local control (LC), metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS) rates (and other toxicities). Results: Twenty-five patients were enrolled between October 2015 and November 2019 and completed the treatment protocol. The median rate of histopathologic regression was 65% (range 0-100) and 20.8% of tumors presented pathologic complete response (pCR). Wound complications were observed in 7/25 patients (28%). Three patients underwent disarticulation by vascular occlusion after plastic reconstruction and one patient was amputated by grade 3 limb dysfunction. After a median follow up of 20.7 months, the 2-year estimated risk of local recurrence, distant metastasis and cause-specific death were 0%, 44.7% and 10.6% respectively. Conclusions: Neoadjuvant SABR appears to improve the pCR for patients with eSTS, with acceptable rate of wound complications. Nevertheless, this benefit should be weighed against the risk of late of vascular toxicity with SABR regimen since, even in a short median follow-up, a higher rate of amputation than expected was observed. A larger sample size with longer follow-up is necessary to conclude the overall safety of this strategy.
