Long-Term Survival of a Breast Cancer Patient with Carcinomatous Pleuritis and Carcinomatous Cardiac Tamponade Successfully Treated by Multimodality Therapy
Summary
A 69-year old woman was admitted to our hospital because of dyspnea and pain in her left breast. Computed tomography revealed a massive quantity of left pleural effusion, a tumor in the left breast(5 cm in diameter), left cervical and supraclavicular lymph node metastasis, and a large left axillary metastatic mass. Based on a core needle biopsy, her breast tumor was diagnosed pathologically as scirrhous carcinoma, which was positive for estrogen receptor/progesterone receptor and negative for HER2 using the FISH assay, and left pleural metastasis was diagnosed cytologically. The carcinomatous pleural effusion was successfully controlled using pleural instillations of pirarubicin HCl and OK-432 after pleural drainage. A near clinical complete response was achieved by EC systemic chemotherapy(6 months)followed by endocrine therapy(letrozole), but 3 months later she was diagnosed cytologically with carcinomatous cardiac tamponade. After operative pericardial drainage, intrapericardial instillations of cisplatin and OK-432 successfully prevented re-accumulation of pericardial effusion. Systemic chemotherapy(weekly paclitaxel)for 11 months and endocrine therapy(letrozole)resulted in a clinical complete response. One year and 10 months after pericardial drainage, she underwent surgery(mastectomy and axillary lymph node dissection level Ⅱ)because of two small tumors in the left breast which were found to be malignant using PET-CT. One tumor(diameter 1.6 cm)was found pathologically to consist of degenerated cancer cells, and another tumor(diameter 2 cm)was diagnosed as recurrent cancer. There was no lymph node metastasis in the axilla except for a single mass(1.4×0.7×0.3 cm), which was composed of extremely degenerative and necrotic non-lymphoid cancerous tissue. Since having the surgery, she has not experienced recurrence on hormone therapy with fulvestrant, and to date she is still alive, 3 years and 5 months since the left pleural metastasis episode.

症例は69歳,女性。呼吸困難にて救急外来受診。左癌性胸膜炎合併左乳癌と診断,胸腔ドレナージ/胸膜癒着術を施行。EC化学療法(約6か月)とletrozoleの途中併用にて胸水消失,左乳癌/左頸部/左鎖骨上窩/左腋窩リンパ節腫瘤の著明な縮小を得たが,letrozole単独治療中に癌性心タンポナーデと診断,心嚢ドレナージ/心嚢内薬剤注入で心嚢液貯留は消失した。weekly paclitaxel化学療法(約11か月)後cCRとなりletrozole単独治療中に乳房再発が出現し,左乳房切除/腋窩郭清手術を施行。救急初診から3年5か月を経過し,画像診断上転移病巣を認めず生存中である。
