52-year-old male was diagnosed in 2004 with a carcinoma of the lower rectum and underwent surgical anterior resection of the rectal tumor which was a well differentiated adenocarcinoma. In 2008 he underwent emergency operation for a perforated pyloric ulcer and then a radical resection of a gastric tumor which infiltrated the entire thickness of the gastric wall. It was a G3 diffuse type adenocarcinoma with signet ring cells, at pT3N2 stage.
A 74 years old male was diagnosed 3 years ago with non small cell lung carcinoma. Accordingly, it was decided that no chemotherapy should be given at that stage. Year and a half later, a new SOL was found in right lung, and right pneumonectomy was performed. On pathology a well to moderately differentiated adenocarcinoma was found. Lymphatic invasion was identified in lung and mediastinum. A revision on previous specimen was performed and it was concluded that the tumor was morphologically different from the previous specimen.
66-year-old female was diagnosed, following persistent cough, with non-operable tumor of her lung with satellite nodules, and chemotherapy was initiated (first Cisplatin and Gemcitabine, and then switched to Tarceva). Response evaluation following the fourth cycle of chemotherapy showed either stability or an initiation of tumor response, but bone scintigraphy that was performed 6 months later revealed an area of increased uptake in the left hemithorax which could be suggestive of a secondary bone lesion.
