Covid-19 and lung cancer: A greater fatality rate?

Background: Currently there are no reported series determining the Covid-19 infected lung cancer patient´s characteristics and outcome that allow us to clarify strategies to protect our patients. In our study we determine whether exists differences in cumulative incidence and severity of Covid-19 infection between lung cancer patients visiting our Medical Oncology department and the reference population of our center (320,000 people), in the current epicenter of the pandemic in Europe (Madrid, Spain). We also describe clinical and demographic factors associated with poor prognosis and Covid-19 treatment outcomes.

Colonic anastomosis and colonic polyp mucosal metastasis of signet ring cell gastric adenocarcinoma.

The mucosal metastasis of adenocarcinomas located in colonic mucosa is not infrequent. We present a clinical report of a patient diagnosed with a gastric multifocal signet ring cell adenocarcinoma without any evidence of visceral dissemination with the exception of mucosal infiltration of signet ring cell adenocarcinoma in a colonic polyp and in the mucosa of previous colonic anastomosis. The histopathological study of suspect lesions in the colonic mucosa is necessary to correctly approach the treatment of these patients.
