Previous studies on the association between hormone replacement therapy (HRT) and breast cancer survival have yielded mixed results. We aimed to perform a meta-analysis to assess the association with all available studies. Relevant studies were identified by searching PubMed and EMBASE to April 2017. We calculated the summary hazard ratios (HRs) and 95% confidence intervals (CIs) using random-effects models. The dose-response relationship was assessed by random-effects meta-analysis and dose-response meta-regression models...

We describe a rare case of secondary breast carcinoma after chronic myeloid leukemia (CML) in a 56-year-old woman. The patient was treated with hydroxyurea and imatinib for CML and achieved complete remission (she has since been taking imatinib as the maintenance therapy). Four years later, the patient noticed a firm and painless lump in the left breast, which was diagnosed as ductal carcinoma in situ based on a percutaneous biopsy of the mass. Simple resection and sentinel lymph node biopsy of the left breast were then performed...

In 2014, the Early Breast Cancer Trialists' Collaborative Group (EBCTCG) reported that post-mastectomy radiation therapy (PMRT) for breast cancer patients with 1-3 cancer-positive lymph nodes is associated with a survival benefit. However, it is not known whether this applies to Japanese patients in daily clinical practice, because this conclusion was based on the results of older, western trials. Therefore, we studied the differences between PMRT results in western breast cancer patients and current practice in Japanese patients...

BACKGROUND: In breast reconstruction using a tissue expander (TE), sufficient coverage of the TE with the pectoralis major (PM) muscle, particularly with a musculofascial flap, is highly important for avoiding postoperative complications. In patients in whom the PM is thin, intraoperative trauma often occurs, leading to troublesome repair. The present study aimed to investigate the usefulness of preoperative measurement of PM thickness in planning of breast reconstruction using a TE. METHODS: In this case-control study, we identified 68 patients (70 breasts) with mammary carcinoma treated with simple mastectomy and TE insertion from April 2014 to December 2016...

BACKGROUND: Although there are a large number of epidemiological studies investigating the etiological role of lifestyle factors in breast cancer, there are few studies on the association between lifestyle factors and breast cancer prognosis. To investigate the influence of lifestyle factors such as diet and physical activity, use of complementary and alternative medicine, and psychosocial factors on prognosis, we designed a large-scale cohort study of female breast cancer patients in Japan...

INTRODUCTION: Ultrasound (US) is conventionally performed to determine effects of neoadjuvant chemotherapy (NAC) on breast cancer. In patients with triple-negative breast cancer (TNBC), higher pathological complete response (pCR) predicts the most favorable survival outcome. We aimed to predict pCR to NAC using echogenicity changes in US region of interest (ROI) in patients with TNBC. METHODS AND MATERIALS: We retrospectively determined clinicopathological characteristics of 52 patients with primary TNBC who underwent NAC...

BACKGROUND: Inflammation plays a pivotal role in the process of carcinogenesis and phytochemicals have anti-inflammatory properties gaining more importance in cancer chemoprevention. The present study aimed to investigate the anti-inflammatory effect of allyl isothiocyanate (AITC) on 7,12-dimethylbenz(a)anthracene (DMBA)- and N-methyl-N-nitrosourea (MNU)-induced mammary carcinogenesis in female Sprague-Dawley rats. METHODS: RT-PCR and western blot analysis showed that inflammatory markers such as NF-κB p65, TNF-α, and IL-6 were overexpressed in mammary tumor tissues...

BACKGROUND: The status of tumor-infiltrating lymphocytes (TILs) is a prognostic factor for triple negative breast cancer (TNBC). Recent studies have shown that programmed cell death 1 (PD-1) or programmed death ligand 1 (PD-L1) is expressed on T lymphocytes or tumor cells modulating antitumor immunity. The regulation of immune checkpoints between tumor cells and T lymphocytes may serve as a target for improvement of TNBC prognosis. We investigated TILs and PD-L1 status in TNBCs before or after preoperative systemic therapy (PST) to elucidate the clinical significance of PD-L1 expression...

MicroRNAs (miRs) are short and highly conserved non-coding RNAs molecules consisting of 18-25 nucleotides that regulate gene expression at post-transcriptional level by direct binding to complementary binding sites within the 3'untranslated region (3'UTR) of target mRNAs. New evidences have demonstrated that miRNAs play an important role in diverse physiological processes, including regulating cell growth, apoptosis, metastasis, drug resistance, and invasion. In chromosomes 11 and 22 of the miR-130 family, paralogous miRNA sequences, miR-130a and miR-130b are situated, respectively...

BACKGROUND: A good therapeutic alliance is associated with better treatment outcomes in diverse types of psychotherapy and patient populations, but little is known about therapeutic alliance in psychotherapies with cancer patients. This study examines the association of therapeutic alliance and treatment outcome in short term psychodynamic psychotherapy (STPP) for breast cancer patients. METHODS: Within a randomized controlled trial, 47 completers of STPP could be included in the analyses...

BACKGROUND: Nanoparticle albumin-bound (nab)-paclitaxel is a solvent-free formulation of paclitaxel that is bound to albumin and has demonstrated improved progression free survival in previous studies of breast cancer. However, it is difficult to treat Japanese patients with metastatic or recurrent breast cancer with the recommended dose of 260 mg/m(2) of (nab)-paclitaxel for more than six cycles due to the occurrence of adverse events. To evaluate the treatment continuity and safety of low-dose nab-paclitaxel, we conducted a phase II study of nab-paclitaxel in patients with metastatic or recurrent breast cancer who had received up to one prior chemotherapy...

BACKGROUND: Trastuzumab following anthracycline causes cardiotoxicity in up to 28% of patients. Although the cardiotoxicity is often irreversible once cardiac dysfunction is detected, the early predictor has not been established yet. METHODS: We prospectively observed breast cancer patients treated with anthracycline or trastuzumab at Tonan Hospital. All patients underwent echocardiography and blood sampling at baseline, and every three months during chemotherapy...

BACKGROUND: T regulatory cells (Tregs) are known to negatively control immune response. The frequency of these cells was inversely correlated with clinical outcomes of breast cancer. CD19(+)CD24(hi)CD38(hi) cells also play a critical role in inflammation and autoimmune disease. However, their function in tumor immune response is less studied. In this study we aimed to determine the role of CD19(+)CD24(hi)CD38(hi) cells and some other clinicopathological variables in increasing the proportion of Tregs in breast cancer patients...

BACKGROUND: Surgical biopsy of metastatic lesions followed by pathological confirmation for the investigation of biomarkers is occasionally proposed as an effective strategy in the treatment of metastatic breast cancer. However, few reports have examined Ki-67 immunohistochemical expression in distant metastatic lesions of breast cancer patients. This study aimed to investigate the clinicopathological significance of subtypes and Ki-67 immunohistochemical expression in metastatic breast cancer lesions...

Estrogen plays crucial roles in the progression of hormone-dependent breast cancers through activation of nuclear estrogen receptor α (ER). Estrogen is produced locally from circulating inactive steroids and adrenal androgens in postmenopausal women. However, conversion by aromatase is a rate-limiting step in intratumoral estrogen production in breast cancer. Aromatase inhibitors (AIs) inhibit the growth of hormone-dependent breast cancers by blocking the conversion of adrenal androgens to estrogen and by unmasking the inhibitory effect of androgens, acting via the androgen receptor (AR)...

BACKGROUND: Breast cancer is the leading type of cancer in Iranian women and affects them at least one decade younger than their counterparts in developed countries. Breast tumor progression and metastasis is accompanied by a decrease in the membranous expression of Syndecan-1 and an increase in its shedding. We measured the level of soluble Syndecan-1 in the sera of Iranian patients with breast cancer. METHODS: The study population included 61 chemotherapy-naïve breast cancer patients and 30 age/sex-matched healthy individuals...
