[A case of recurrent breast cancer with carcinomatous pleurisy successfully treated with combined chemoendocrine-therapy of CTF (CPA, THP and 5-FU) and anastrozole following instillation therapy 12 years after radical mastectomy].

A 52-year-old female underwent radical mastectomy at the age of 41 for left breast cancer (n0, positive for ER). After a few years of adjuvant TAM therapy, follow-up was stopped at the age of 50 with no recurrence. She had suffered from symptoms of cold since January 2001 and came to our hospital complaining dyspnea on February 11. CXP showed pleural effusion of the entire thoracic cavity and she was admitted to the hospital immediately. Pleural exudate cytodiagnosis showed carcinomatous pleurisy; however, dyspnea and thoracic effusion were improved by continuous thoracic drainage and instillation therapy. Various examinations demonstrated that the carcinomatous pleurisy was due to recurrent breast cancer. They also showed local recurrence, left supraclavicular lymph node metastasis and multiple bone metastasis. Thus, combined chemoendocrine-therapy of CTF (CPA, THP and 5-FU) and anastrozole was administered. After 6 cycles of CTF, the carcinomatous pleurisy, local recurrence and left supraclavicular lymph node metastasis were diagnosed as CR by CXP, chest CT and US and multiple bone metastasis were diagnosed as PR by bone scintigram. The patient continues to be treated on an outpatient basis with no recurrence about one year after the beginning of the treatment (6 months after CTF 6 cycles) and she is taking anastrozole continuously.
