ABSTRACT: A 79-year-old male whose chest X-ray revealed a localized reticular shadow in health check was once treated medically with a diagnosis of interstitial pneumonia. Regardless of the treatment, the shadow increased in its size. Positron emission tomography (PET)-computed tomography(CT) was suggestive of a primary lung cancer in clinical stage IIIA. CA19-9 and CEA were 3,568.5 U/ml and 178.2 ng/ml respectively, and a left lower lobectomy was performed. The postoperative course was uneventful. Both tumor markers declined shortly after the surgery. But they increased in 8 months after the surgery associated with tumor recurrence. In spite of chemotherapy, the patient was expired 15 months following the surgery. Immunohistochemical staining showed the tumor was a well differentiated adenocarcinoma with positive findings of both CEA and CA19-9.

ABSTRACT: We report a case of complete remission after treatment with tegafur-uracil (UFT)/Leucovorin (LV) therapy for pulumonary metastasis of rectal cancer. A 56-year-old male was admitted to our hospital with a diagnosis of rectal cancer (Ra, type2). Chest CT on admission demonstrated bilateral lung metastases (rt S2 and lt S4). After anterior resection of the primary tumor, oral UFT/LV was administered (UFT 400 mg/LV 75 mg, 4-week administration and 1-week no-administration period) on an outpatient basis. After 2 courses, chest CT revealed reduction of both metastases, and complete resection of the metastases by video assisted thoracic surgery (VATS) was planned. Pathological findings of a specimen revealed no residual cancer cells, indicating a complete response to UFT/LV therapy. After these treatments, combined therapy of UFT/LV was continued for 3 months, and the single administration of UFT was continued for 1 year. The patient experienced no adverse reactions, and has had no recurrent disease in 4 years. Oral UFT/LV therapy is considered to be a promising regimen for patients with resectable metastatic lesion from a standpoint of clinical efficacy and safety.

ABSTRACT: A case of combined germ cell tumor and adenocarcinoma that arose in the colon of a 62-year-old man is described. The clinical and pathological findings are presented. The patient had widespread metastases at diagnosis and poor prognosis after operation (right hemicolectomy) was performed in spite of receiving chemotherapy. Pathologically, the germ cell tumor was composed of a yolk sac tumor and choriocarcinoma. Further, all the metastatic lesions showed a germ cell phenotype. An extragonadal germ cell tumor is extremely rare. To our knowledge, only a few cases have been reported in the English-language literature. Our present report will contribute to the understanding of the characteristics of this rare neoplasm.
