RESUMO
BACKGROUND: Solid tumors are a common cause of secondary thrombocytosis, which has been identified as a prognostic factor in various cancers. However, the impact of thrombocytosis on the prognosis of gastric cancer is not yet well defined. The aim of this study was to assess the prevalence and prognostic value of thrombocytosis in patients with gastric cancer. METHODS: This was a retrospective study of patients with gastric carcinoma treated surgically, with curative intent, in our hospital, Centro Hospitalar Vila Nova de Gaia/Espinho, between January 2009 and December 2019. Clinical files were consulted and clinicopathological characteristics were analyzed. RESULTS: In the present sample (n = 352), the prevalence of pretreatment thrombocytosis was 16.5%. Thrombocytosis was associated with more advanced T stage, greater number of metastatic nodes, and more frequent lymphatic and venous permeation. The presence of thrombocytosis had a negative impact on disease-free survival (hazard ratio [HR] 3.54, 95% confidence interval [CI] 2.35-5.33, P < .001) and overall survival (HR 4.45, 95% CI 2.95-6.71, P < .001). CONCLUSIONS: The presence of pretreatment thrombocytosis had a negative impact on overall survival and disease-free survival and thus could be used as an independent prognostic factor.
RESUMO
Superior mesenteric artery syndrome designates compression of the third part of the duodenum between the superior mesenteric artery and the aorta. This condition has a low incidence, being more common in thin young women. Nutcracker syndrome is compression of the left renal vein between the superior mesenteric artery and the aorta. Both entities are rare, and their coexistence has been reported in a few cases. Conservative treatment targeting weight gain is sufficient in most cases. An association between the superior mesenteric artery syndrome and acute pancreatitis has rarely been reported. We intend to describe the case of an 18-year-old girl who was admitted to the emergency room with epigastric pain and emesis. Our investigation revealed acute acalculous pancreatitis. During work-up, we discovered superior mesenteric artery syndrome and a compressed left renal vein. The patient is on conservative treatment, and her symptoms have improved.
A síndrome da artéria mesentérica superior designa compressão da terceira parte do duodeno pela artéria mesentérica superior e a aorta. Essa condição tem uma baixa incidência, sendo mais comum em mulheres jovens magras. A síndrome de quebra-nozes resulta da compressão da veia renal esquerda pela artéria mesentérica superior e a aorta. Ambas as entidades são raras, e a sua coexistência foi descrita em poucos casos. Tratamento conservador com o objetivo de ganho ponderal é suficiente na maioria dos casos. A associação entre a síndrome da artéria mesentérica superior e a pancreatite aguda foi raramente relatada. Pretendemos descrever o caso de uma jovem de 18 anos que recorreu ao serviço de urgência com epigastralgia e vômitos. A investigação realizada revelou pancreatite aguda alitiásica. Durante o estudo complementar, foi identificada a síndrome da artéria mesentérica superior, bem como uma veia renal esquerda comprimida. A paciente encontra-se em tratamento conservador, apresentando melhora clínica.

RESUMO
BACKGROUND: The late adverse effects of radiotherapy are caused by microvascular injury or depletion of differentiated cells. METHODS: Here we describe a clinical case of a late and unusual complication related to radiotherapy, in a patient with a history of squamous cell carcinoma of the anal canal. RESULTS: The patient presented with a large perianal vegetating lesion suspicious of local recurrence, however the biopsy of the lesion did not show malignancy. CONCLUSION: Fortunately, all is not as it seems, and what appeared as a suspected relapse turned out to be a benign reactive lesion, consequence of radiotherapy.
