[A Long-Surviving Case of Locally Advanced Breast Cancer with Multiple Lung Metastasis].

We report a case of right advanced breast cancer with multiple lung metastases in a 66-year-old woman. Her breast cancer( invasive ductal carcinoma, cT4bN1M1, Stage Ⅳ)was resected in October 2007(mastectomy plus axillary lymph node dissection)after local arterial infusion therapy(total dose 5-FU 4,735 mg plus adriamycin 180 mg), which caused bilateral lung arterial embolism due to deep vein thrombosis in right her leg. She had to be treated by anticoagulant therapy, mechanical ventilation and placement of IVC filter before her operation.

[A Case of Recurrent Breast Cancer with Multiple Bone Metastasis Effectively Treated by CDK4/6 Inhibitor in Addition to Aromatase Inhibitor].

We report a case of recurrent breast cancer with multiple bone metastasis in a 62-year-old woman. Her breast cancer (invasive ductal carcinoma, T2N0M0, Stage ⅡA)was resected in 2001(partial mastectomy plus axillary lymph node dissection) with adjuvant chemotherapy(UFT)and irradiation to her left remnant breast. In February 2018, she complained of severe pain in right femoral joint and hip.

[A Case of Pyloric Stenosis Due to Gastric Metastasis of Breast Cancer].

We report a case of left advanced breast cancer(T4N1M0, Stage ⅢA)in a 67-year-old woman. In August 2010, her breast cancer(triple-negative invasive ductal carcinoma)was resected(mastectomy plus axillary lymph node dissection) with adjuvant chemotherapy(TC)and irradiation to her chest wall. In July 2018, she experienced recurrent vomiting.

A Case of Breast Cancer in a Patient with a Congenital Pectoralis Muscle Defect.

Congenital pectoral muscle defects are very rare, and when accompanied by limb defects, they are called Poland syndrome. A woman in her 70s, 4 years after partial mastectomy for breast cancer, underwent mastectomy for a local recurrence. During the operation, the pectoralis major and minor muscles were found to be defective.

[A Useful Method of Nipple-Side HydroMARK-Marking before Neoadjuvant Chemotherapy in the Breast Preserving Surgery-A Case Report with pCR of the Triple Negative Breast Cancer].

When the primary breast cancer disappears by neoadjuvant chemotherapy, it is often difficult to detect it during the breast preserving surgery. Before neoadjuvant chemotherapy, preoperative nipple-side HydroMARK-marking, which was made of titanium coil and hydrogel, was a very useful and effective method because of its fine detection by ultrasonography. We report a case of 51-year-old female with the triple negative breast cancer(TNBC).

[A Case Report of Recurrent Bleeding and Massive Malodorous Effusion Due to Skin Invasion of Advanced Breast Cancer Successfully Treated with Mohs' Paste].

We report a case involving a 65-year-old woman with skin invasion and destruction by left large breast cancer(T4cN0M0, Stage ⅢB). She had severe anemia with recurrent bleeding on the cancer surface and needed blood transfusion, and massive malodorous effusion from the skin lesion resulted in hypoalbuminemia and recurrent bacteremia. Metronidazole gel treatment for malodorous effusion and postmenopausal hormonal therapy were administered at first.

Anti-E Detected in a 7-Month-Old Infant with Acute Lymphoblastic Leukemia after Transfusion.

Background: Only a few cases of infantile anti-red blood cell alloantibody production have been reported.

Methods: A 7-month-old girl with acute lymphoid leukemia developed anti-E alloantibody 13 days after transfusion of E-positive red blood cells. Antibody screening was performed before and at 2, 6, 13, 18, 27, 34, and 49 days after red blood cell transfusion.

[Subclavian Artery Hemorrhage Related to Everolimus in a Patient with Recurrent Breast Cancer--A Case Report].

A 53-year-old woman underwent breast-conserving surgery for right breast cancer (invasive ductal carcinoma, T1cN0M0, ly+, stage ⅠA, ER+, PR+, HER2-) 5 years previously. During treatment with tamoxifen, massive recurrence in the axillary lymph nodes was found. First- through fourth-line chemotherapy were tried, but they all failed.

Decreased expression of SOCS-3 mRNA in breast cancer with lymph node metastasis.

Signal transducers and activators of transcription (STATs) play a pleomorphic role in signal transduction, similarly to an oncogene. Suppressors of cytokine signaling (SOCS) inhibit STAT pathways. In breast cancer, little is known about the correlation among STATs, SOCS, and clinicopathological/biological features.

Elevated cyclooxygenase-2 expression is associated with histological grade in invasive ductal breast carcinoma.

Purpose: The aim of this study was to evaluate the expression of cyclooxygenase-2 in human breast cancer using immunohistochemistry and to determine whether the expression of cyclooxygenase-2 is associated with clinicopathological factors in invasive ductal breast carcinoma.

Methods: Cyclooxygenase-2 expression was investigated by immunohistochemistry in 30 invasive ductal breast carcinoma specimens and relationships between cyclooxygenase-2 expression and age, histological grade, histological type, nodal status, and hormone receptor status were evaluated.

Results: Cyclooxygenase-2 expression was found in 56.

Esthetic evaluation of immediate breast reconstruction after nipple-sparing or skin-sparing mastectomy.

Background: It has been reported that immediate autologous tissue breast reconstruction after nipple-sparing mastectomy (NSM) or skin-sparing mastectomy (SSM) is esthetically superior to autologous tissue reconstruction after conventional mastectomy (CM). We evaluated reconstructed breasts to determine whether these methods contribute to breast appearance other than skin texture.

Methods: Between April 1992 and September 2001, forty-two patients underwent immediate breast reconstruction using autologous tissue.

Thymidylate synthase and dihydropyrimidine dehydrogenase gene expression in breast cancer predicts 5-FU sensitivity by a histocultural drug sensitivity test.

Thymidylate synthase (TS), Dihydropyrimidine dehydrogenase (DPD) and Thymidine Phosphorylase (TP) gene expressions are reported to be predictive markers for 5-fluorouracil (5-FU) sensitivity in gastrointestinal cancer. However, in breast cancer, it is still controversial whether those molecular markers predict 5-FU sensitivity or not. One possible reason for the difficulty may be the histological heterogeneity in breast cancer specimens.

Inverse correlation between the expression of O6-methylguanine-DNA methyl transferase (MGMT) and p53 in breast cancer.

Background: Expression of O(6)-methylguanine-DNA methyl transferase (MGMT), a DNA repair protein, has been associated with tumor resistance to alkylating agents such as cyclophosphamide. Promoter hypermethylation of MGMT is a strong predictor of survival, and expression of mutant p53 protein may be associated with downregulated MGMT expression in brain tumors. In order to clarify further the correlation between MGMT and p53 expression, we investigated the expression levels of both MGMT and p53 in breast cancer.

Magnetic resonance imaging of the metal clip in a breast: safety and its availability as a negative marker.

Purpose: This study assesses magnetic resonance (MR) safety of the stainless-steel clip inserted after stereotactic-guided directional vacuum-assisted biopsy (DVAB) of the breast, and evaluates its imaging value.

Methods: We used a sausage as a substitute breast and inserted the clip into it. The MR images of the substitute were scanned using a breast coil, and it was then dissected.

Correlation among intratumoral blood flow in breast cancer, clinicopathological findings and Nottingham Prognostic Index.

Background: The purpose of this study was to evaluate the correlation among intratumoral blood flow as assessed by color Doppler ultrasonography, clinicopathological findings and the Nottingham Prognostic Index (NPI).

Methods: Twenty-seven patients with breast cancer were examined. All patients received surgical treatment.

Endoscopic resection of benign breast tumors: retromammary space approach.

Endoscopic surgery is characterized by the creation of a working space. At our department, we have obtained good results with a retromammary space approach in which the tumor is resected after creation of a working space in the retromammary space. The special instruments used for this purpose comprise an endoscopic vein harvesting system to dissect the retromammary space, a dissecting balloon to compress the space to achieve hemostasis, and laparosonic coagulating shears to incise the tumor.
