Background: Celecoxib and low-dose aspirin might decrease risk of breast cancer recurrence. Methods: In the Canadian Cancer Trials Group MA.27, postmenopausal hormone receptor-positive breast cancer patients were randomly assigned (2 × 2) to adjuvant exemestane or anastrozole, and celecoxib or placebo. Low-dose aspirin of 81 mg or less was a stratification factor. Due to concerns about cardiac toxicity, celecoxib use was stopped in December 2004, while stratification by aspirin use was removed through protocol amendment...

Arthralgia, myalgia, paresthesia, reduced bone mineral density, vasomotor side effects including hot flashes and night sweats, genitourinary symptoms including decreased libido, vaginal dryness and dyspareunia are common side effects of aromatase inhibitors. Unlike the common side effects, the information on neurological side effects like hallucination of aromatase inhibitor was limited in literature cases. Herein, we reported a case of hallucination related to anastrozole in a patient with metastatic breast cancer...

Although anastrozole (Anas) plays a key role in the management of endocrine sensitive post-menopausal (PM) breast cancer (BC), there is much variability in its efficacy and tolerability. Anas-associated musculoskeletal symptoms (MS) and other adverse reactions, such as hot flashes (HF) and vaginal dryness/dyspareunia (VDD), are common and can affect the quality of life of BC patients, even sometimes leading to treatment withdrawal. The aim of this study was to determine the clinical and demographic factors associated with these adverse events...

Anastrozole is a non-selective aromatase inhibitor for adjuvant breast cancer therapy in postmenopausal women. Cutaneous adverse events have been reported. We observed a 64-year-old female patient with a medical history of locally advanced breast cancer of her right breast that was treated with radiotherapy and adjuvant drug therapy with anastrozole. She developed a segmental bullous eruption limited to the cancer-affected breast. Cessation of the aromatase inhibitor and systemic therapy with prednisolone cleared the lesions completely...

BACKGROUND: Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole. We investigated the schedule and type of aromatase inhibitors to be used as adjuvant treatment for hormone receptor-positive early breast cancer. METHODS: FATA-GIM3 is a multicentre, open-label, randomised, phase 3 trial of six different treatments in postmenopausal women with hormone receptor-positive early breast cancer...

OBJECTIVES: In Sweden, breast cancer (BC) represents 30% of newly diagnosed cancers and is the most common cancer in women. For hormone-dependent BC, endocrine therapies varying in efficacy and price are available. The aim of this study is to assess the cost effectiveness of fulvestrant 500 mg as a second-line hormonal therapy for postmenopausal women with estrogen receptor-positive metastatic or locally advanced BC versus letrozole, anastrozole, and exemestane in Sweden. METHODS: A three-state (pre-progression, post-progression, and death) partitioned-survival model was used to estimate progression-free (PFS) and overall survival (OS) by extrapolating trial results beyond the trial period to capture costs and benefits over a lifetime perspective...

A 50s-year-old woman underwent left partial mastectomy with axillary lymphadenectomy for breast cancer. Histological examination indicated invasive ductal carcinoma, pT1c, pN0, Stage I , ly(+), ER(+), PgR(+). She received adjuvant therapy with tamoxifen and 50 Gy of irradiation to the residual breast. Four years after mastectomy, she was found to have left Rotter lymph node metastasis; then, anastrozole was administered instead of tamoxifen. Nine months later, she was found to have liver metastasis. Immunohistostaining revealed that the breast cancer was HER2-positive; she received AC followed by paclitaxel(PTX)with trastuzumab(T), and achieved complete response(CR)...

We report the case of a patient in which S-1 plus anastrozole was administered as first-line chemotherapy for Stage IV breast cancer with skin invasion, multiple lymph node metastasis, and lymphangitis carcinomatosis. A 77-year-old woman had a mass destroyed immediately outside the axilla with dry coughs. An 11mm unpalpable mass in the right breast and an axillary mass were confirmed to be scirrhous carcinoma(Luminal type B), respectively, by core needle biopsy. In one course, S- 1(100mg/day)therapy involves taking 2 courses of 14 days of administration and 7 days off the drug...

While skull base metastases from breast cancer are not uncommon, there are relatively few reported cases in the literature. We report a case of skull base metastasis of breast cancer that resulted in dysphasia, odynophagia, and dysarthria. The case involved a woman in her 50 s who was diagnosed with cancer of the right breast(cT4N1M0, cStage III B)at another medical institution 9 years previously and who underwent a partial mastectomy and an axillary lymph node dissection following neoadjuvant chemotherapy...

The rate of local recurrence after mastectomy is reportedly similar to that of one-stage reconstruction. Most recurrences are in the skin or chest wall, while recurrence in the reconstructed breast is rare and the causes are uncertain. We report a case of a 42-year-old female who underwent partial mastectomy for left breast cancer with cT4aN0M1(PUL), cStage IV after endocrine therapy 3 years ago. Histopathological diagnosis was solid-tubular carcinoma. She had been treated with only endocrine therapy but diagnosed with local recurrence in the left breast...

BACKGROUND: The pedicled transverse rectus abdominis myocutaneous (TRAM) flap is a reliable reconstructive option in breast cancer patients; however, it carries known risk of donor site hernia formation. Some hormonal therapy drugs have been associated with hernia formation in animal models. Minimal data exist concerning impact of hormonal therapy for breast cancer on abdominal donor site complications after breast reconstruction. METHODS: Patients who underwent TRAM flap for breast cancer or high-risk status at a single institution by the senior author from 2003 to 2015 were identified...

BACKGROUND: Pazopanib is an oral tyrosine kinase inhibitor registered for metastatic renal cell carcinoma and soft tissue sarcoma. Liver toxicity is a common side effect for this class of agents. The current opinion is that in case of severe liver toxicity pazopanib should be interrupted and restarted at a lower dose after returning to Common Terminology Criteria for Adverse Events (CTCAE) grade 1. After recurrence of liver toxicity at the lower dose it is advised to permanently stop pazopanib...

Purpose: Anastrozole (ANS) is an aromatase inhibitor that is widely used as a treatment for breast cancer in postmenopausal women. Despite the wide use of ANS, it is associated with serious side effects due to uncontrolled delivery. In addition, ANS exhibits low solubility and short plasma half-life. Nanotechnology-based drug delivery has the potential to enhance the efficacy of drugs and overcome undesirable side effects. In this study, we aimed to prepare novel ANS-loaded PLA-PEG-PLA nanoparticles (ANS-NPs) and to compare the apoptotic response of MCF-7 cell line to both ANS and ANS-loaded NPs...
