Patient description (medical language): A 63-year-old man comes to the clinic for recent unintentional weight loss. The patient also has epigastric discomfort after meals. He has no known medical problems and takes no medications. His blood pressure is 130/75 and pulse rate is 88/min. He is not febrile. Upper endoscopy shows a lesion in the stomach that shows typical features of diffuse-type adenocarcinoma presenting with signet ring cells that do not form glands.

Patient description (patient's own words): I went to the clinic because I had been losing so much weight that it was concerning. I'm a 63-year-old guy, and it is something rather unusual. I'm always suffering from stomachache after every meal. I've never been sick, and I don't take any medicine. The doctor took my blood pressure and told me it was 130/75, and my pulse rate was 88/min. I'm not febrile! I also had to do an endoscopy, and they found a lesion in my stomach that shows typical features of stomach cancer. I'm totally devastated...

Does the patient match the trial criteria? 1
