Renal cell carcinoma (RCC) worldwide has an incidence of 431,288 cases per year, causing 179,368 deaths in 2020. However, despite its incidence, the development of pancreatic metastasis (MP) from RCC is unusual. The aim of this manuscript was to report the case of a patient with a PM of a RCC. This is a 56-year-old female patient, underwent right nephrectomy 132 months earlier for RCC. While she was in adjuvant immunotherapy, in a routine imaging control, it was found a tumor lesion in the body and the tail of the pancreas. So, she underwent surgery, performing a corpora-caudal pancreatectomy with splenic preservation. Postoperative evolution was correct, without complications, and she was discharged on the 4th day after surgery. The report of the study of the surgical piece with an immunohistochemical study included, conclusive of PM of RCC. Currently, the patient is in good general condition and restarted chemotherapy with monoclonal antibodies. Frequent and prolonged follow-up of patients with a history of RCC facilitates timely diagnosis and treatment of PM, facilitating the best prognosis for patients, with higher survival rates.

Purpose: Worldwide, gastric cancer (GC) is the 5th cancer with the highest incidence and the 4th in mortality. To reduce it, one strategy is to diagnose preneoplastic lesions (PNL): atrophic gastritis (AG), intestinal metaplasia (IM), and dysplasia (DYS); to form risk groups on which to focus surveillance efforts as are first-degree relatives (FDR). The aim of this study was to determine prevalence of gastric PNL in FDR of patients with GC, and to study association with sex, age, and Helicobacter pylorii (Hp) infection. Methods: Cross-sectional study. One hundred and ten FDR, aged between 50 and 65 years, 54.5 female, obtained through convenience sampling, were studied. Biodemographic data survey and upper gastrointestinal endoscopy with histological study were applied according to Sidney protocol, and focal lesions found. Diagnosis of these lesions and condition of mucosa was carried out by applying OLGA and OLGIM systems. Descriptive statistics, estimation of prevalence, odds ratio (OR), and 95% confidence intervals (95CI) were calculated. Results: Median age of study group was 56.5 years. Prevalence of PNL, AG, IM, and DYS were 86.4%, 82.7%, 54.5%, and 12.7% respectively. Advanced stages of OLGA and OLGIM were verified in 18.0% and 16.3% respectively. No association with sex, age, and Hp infection were found ([OR 3.10; 95CI 1.0; 9.64]; [OR 0.74; 95CI 0.26; 2.14]; [OR 0.58; 95CI 0.12; 2.77]) respectively. Conclusion: FDR of patients with GC have a high prevalence of PNL, which makes them a risk group in which endoscopic surveillance should be applied. [ABSTRACT FROM AUTHOR]

Surgical treatment of hepatic cystic echinococcosis is associated (among others), with a current recurrence rate of up to 27%; although recurrence after total resection of an intact cyst is rare. In general, recurrence occurs as a result of the spillage of living parasitic structures into a cavity, or of leaving germinal residues, daughter vesicles, or protoscolices during surgery. Recurrence is usually asymptomatic, so the diagnosis depends almost exclusively on a rigorous and prolonged follow-up, with clinical controls, serological determinations, and images. Treatment may include the use of albendazole, followed by interventional radiology techniques or surgery. The aim of this manuscript was to generate a reading document regarding the recurrence of hepatic cystic echinococcosis. [ABSTRACT FROM AUTHOR]
