RESUMEN
Unusual lung adenocarcinoma with morule-like components is characterized by uniform, tightly packed spindle-shaped cells filling the lumens of neoplastic glandular structures. We present a case of a 78-year-old woman who presented with a part-solid ground-glass nodule in the upper lobe of the right lung. Following right upper lobectomy, histological examination revealed adenocarcinoma in-situ with multiple morule-like intra-alveolar proliferative nests of epithelial cells. Immunostaining was positive for thyroid-transcription factor 1 in the tumor cells and morule-like components. The tumor was also positive for an epidermal growth factor receptor mutation. This case provides valuable insights about lung adenocarcinoma in-situ with morule-like components.
RESUMEN
We herein administered combination-therapy using a personalized vaccination and the oral administration of UFT/UZEL for the treatment of either advanced or recurrent colorectal cancer. Safety and the efficacy of this new treatment modality were evaluated. Eight patients were enrolled in this clinical trial from July 2005 to May 2006. Up to 4 kinds of peptide vaccines which were selected according to the immune response of each patient were injected hypodermically every week. At the same time, UFT (300 mg/m2/day) and UZEL (75 mg/day) were also administered orally for 28 days followed by a 7-day rest period. Regarding the adverse events, callosity, a type of leukopenia, and liver-dysfunction, such as hyperbilirubinemia, an increase in the aminotransferase were observed. During the clinical evaluation after the end of the 2 courses, 3 cases showed progressive disease (PD) while 5 cases showed stable disease (SD). Our findings indicate that additional peptide vaccine therapy with UFT/UZEL, can be administered without compromising the patient's safety. Moreover, the use of UFT/UZEL does not normally interfere with the normal course of immune-therapy.
