Case Reports[A case of pericardial tamponade caused by recurrent breast cancer treated with intrapericardial and intrapleural infusion of cisplatin (CDDP)].
Breast cancer rarely metastasizes to the pericardial cavity to cause cardiac tamponade. We have recently experienced a case of pericardial tamponade due to recurrent breast cancer. A 41-year-old woman who underwent modified radical mastectomy for a right breast cancer (T(1)N(3)M(0), Stage IIIA) 8 years and 8 months ago, was admitted for dyspnea and cough. ⋯ After local chemotherapy with CDDP, systemic chemotherapy of CPT-11 was started. Thereafter the patient was discharged from the hospital and recovered her daily activities. This case indicates that intrapericardiac application of CDDP was effective for carcinomatous cardiac tamponade without serious side effects.

Capecitabine, an oral fluoropyrimidine carbamate, is adopted worldwide. As the treatment for metastatic colorectal cancer, capecitabine showed at least comparable efficacy with a favorable safety profile to bolus 5-FU/LV. In a large phase III trial (Xeloda Adjuvant Chemotherapy Trial: X-ACT), as the adjuvant treatment of patients with resected stage III colon cancer, capecitabine showed at least comparable disease-free survival, overall survival, and relapse-free survival with a favorable safety profile to bolus 5-FU/LV. ⋯ The median time to disease progression was 169 days and the median overall survival was 617 days. Hand-foot syndrome (HFS), a characteristic adverse event of capecitabine, was observed in 73.3% of the patients, but the grade 3/4 was observed in 13.3% of the patients and only one patient discontinued the treatment due to HFS. An immediate approval of capecitabine in Japan is expected.

Breast cancer is one of the most common malignancies among Japanese women. Approximately 40,000 new patients are diagnosed annually. ⋯ It was widely accepted that for breast cancer as a systemic disease, appropriate systemic treatment of either chemotherapy and endocrine therapy improved the survival. We describe here the contributions of new agents to the improvement in survival for breast cancer patients and introduced the concept of dose density.

Review[Timeline from discovery of 5-FU to development of an oral anticancer agent S-1 and its drug concept].
C. Heidelberger et al left great gifts to us. Approximately 50 years have elapsed since their discovery of 5-FU in 1957 before eventually elucidating the mechanisms by which the drug exerts its pharmacological actions and provokes its adverse reactions. ⋯ From 2001 to 2005, S-1 was approved for the treatment of head and neck cancer, colon cancer, non-small cell lung cancer, and breast cancer. S-1 has been applied to acquire its expanded indications for the treatment of pancreatic cancer and biliary tract cancer. We are confident that the combined regimen of S-1 with other anticancer agents and with other therapeutic modalities will contribute to the routine medical practice of cancer treatment in the future.

Comparative Study[Comparison of ramosetron and azasetron for prevention of acute and delayed cisplatin-induced emesis in lung cancer patients].
We performed a retrospective study that compared the efficacy and safety of ramosetron with azasetron in a case of acute and delayed emesis induced by cisplatin (CDDP)-included chemotherapy in patients with lung cancer. The study subjects were 100 lung cancer patients treated with combination therapy of cisplatin, ifosfamide, irinotecan (CIC therapy). The ramosetron group and azasetron group received, respectively, ramosetron 0.3 mg or azasetron 10 mg intravenous injection, 30 minutes prior to CDDP. ⋯ Adverse effects were observed in 27 cases in the ramosetron group and 24 cases in the azasetron group. However, because the symptoms were all mild, we did not consider there was any safety problem. In conclusion, it was suggested that ramosetron is a clinically useful treatment for acute and delayed emesis induced by cisplatin-induced chemotherapy in patients with lung cancer.
