- 17-Week Delay Surgery after Chemoradiation in Rectal Cancer with Complete Pathological ResponsePublication . Santos, M.; Gomes, M.; Moreno, F.; Rocha, A.; Lopes, C.Neoadjuvant chemoradiation (CRT) followed by curative surgery still remains the standard of care for locally advanced rectal cancer (LARC). The main purpose of this multimodal treatment is to achieve a complete pathological tumor response (ypCR), with better survival. The surgery delay after CRT completion seems to increase tumor response and ypCR rate. Usually, time intervals range from 8 to 12 weeks, but the maximum tumor regression may not be seen in rectal adenocarcinomas until several months after CRT. About this issue, we report a case of a 52-year-old man with LARC treated with neoadjuvant CRT who developed, one month after RT completion, an acute myocardial infarction. The need to increase the interval between CRT and surgery for 17 weeks allowed a curative surgery without morbidity and an unexpected complete tumor response in the resected specimen (given the parameters presented in pelvic magnetic resonance imaging (MRI) performed 11 weeks after radiotherapy completion).

- Complexo de Von Meyenburg ou Metástases Hepáticas? Caso Clínico e Revisão da LiteraturaPublication . Silveira, I.; Mota, F.; Ferreira, J.; Dias, R.; Leuschner, P.Hepatic lesions represent a common finding in clinical practice. Bile ducts hamartomas, also known as Von Meyenburg complex, are benign hepatic malformations composed of small dilated cystic bile ducts lined by fibrous stroma. They represent a rare and asymptomatic clinic-pathological entity. Imagiological findings are variable, and may present as multiple small scattered lesions, or rarely as a single nodule. These findings may resemble secondary lesions and, although benign, there are cases of progression to colangiocarcinoma. Thus it is important to include this complex in the differential diagnoses of focal hepatic lesions, being necessary a detailed investigation for their differentiation. This case represents an atypical presentation of a rare and not frequently considered entity in clinical practice

- Tumor regression grades: can they influence rectal cancer therapy decision tree?Publication . Santos, M.; Silva, C.; Rocha, A.; Matos, E.; Nogueira, C.; Lopes, C.BACKGROUND: Evaluating impact of tumor regression grade in prognosis of patients with locally advanced rectal cancer (LARC). MATERIALS AND METHODS: We identified from our colorectal cancer database 168 patients with LARC who received neoadjuvant therapy followed by complete mesorectum excision surgery between 2003 and 2011: 157 received 5-FU-based chemoradiation (CRT) and 11 short course RT. We excluded 29 patients, the remaining 139 were reassessed for disease recurrence and survival; the slides of surgical specimens were reviewed and classified according to Mandard tumor regression grades (TRG). We compared patients with good response (Mandard TRG1 or TRG2) versus patients with bad response (Mandard TRG3, TRG4, or TRG5). Outcomes evaluated were 5-year overall survival (OS), disease-free survival (DFS), local, distant and mixed recurrence. RESULTS: Mean age was 64.2 years, and median followup was 56 months. No statistically significant survival difference was found when comparing patients with Mandard TRG1 versus Mandard TRG2 (p = .77). Mandard good responders (TRG1 + 2) have significantly better OS and DFS than Mandard bad responders (TRG3 + 4 + 5) (OS p = .013; DFS p = .007). CONCLUSIONS: Mandard good responders had a favorable prognosis. Tumor response (TRG) to neoadjuvant chemoradiation should be taken into account when defining the optimal adjuvant chemotherapy regimen for patients with LARC

- Diagnóstico prenatal y seguimiento del quiste esplénicoPublication . Prior, C.; Miguez, R.; Teixeira, F.; Castro, J.Los quistes esplénicos congénitos son entidades poco frecuentes, particularmente en la edad pediátrica. En la literatura especializada existen pocos casos publicados con diagnóstico durante el período prenatal. Los autores describen 2 casos clínicos, identificados por ecografía prenatal a las 34 y 30 semanas de gestación, y su evolución posnatal hasta su resolución espontánea a los 5 meses y a los 2 años de vida, respectivamente. Se revisa la etiología, clínica y evolución de esta patología.Congenital splenic cysts are uncommon entities, especially in children. Few cases diagnosed in the prenatal period have been reported in the literature. We describe two cases that were identified by prenatal sonography at 34 and 30 gestational weeks. Their follow- up until spontaneous full regression at 5 months and 2 years, respectively, is discussed. The etiology, clinical findings, and clinical course of this entity are reviewed.
