Background: The prognosis in patients with breast cancer with isolated locoregional recurrence (ILRR) without simultaneous distant metastases after immediate breast reconstruction (IBR) remains unknown. We aimed to investigate the prognosis in this patient population.

Methods: This multi-institutional retrospective observational study evaluated 3295 patients with primary breast cancer who underwent IBR at 12 Japanese medical facilities between January 1, 2008 and December 31, 2016.

Introduction: Involved surgical margins are risk factors for local recurrence and re-excision is often difficult, particularly in patients with breast cancer undergoing immediate breast reconstruction (IBR). However, the magnitude of the effect of radiation therapy on preventing local recurrence for breast cancers with involved margins has not been sufficiently assessed.

Materials And Methods: We retrospectively assessed sites of involved surgical margins and local recurrence after mastectomy with IBR in patients with early breast cancer between 2008 and 2016.

Background: In breast cancer patients receiving neoadjuvant chemotherapy (NAC), immediate breast reconstruction (IBR) as a breast cancer treatment option remains controversial. We assessed the impact of NAC on surgical and oncological outcomes of patients undergoing IBR.

Methods: This was a retrospective multicenter study of 4726 breast cancer cases undergoing IBR.

Background: One barrier to the widespread use of breast reconstruction (BR) is physicians' perception that BR adversely affects breast cancer prognosis. However, there is limited information regarding physicians' understanding of the impact of BR on patient prognosis and which physicians have misunderstandings about BR.

Methods: We conducted an e-mail survey regarding the impact of BR on the prognosis of patients with breast cancer among members of the Japanese Breast Cancer Society.

Background: Little information is available about the clinical and pathologic characteristics of local recurrence (LR) after nipple-sparing mastectomy according to the locations of LR.

Methods: This study classified 99 patients into the following two groups according to the location of LR after nipple-sparing mastectomy: nipple-areolar recurrence (NAR) group and other locations of LR (oLR) group. The study evaluated whether the location of LR was associated with disease-free survival (DFS) after LR resection.

Background: Osteoporosis is a major side effect of aromatase inhibitors (AIs), which are greatly effective in the treatment of breast cancer. However, there are no satisfactory measures against osteoporosis. In this multicenter, randomized, comparative study, we evaluate the efficacy of denosumab for preventing loss of bone mineral density (BMD) induced by adjuvant therapy with AI s in breast cancer patients with normal BMD.

Background: Aromatase inhibitors (AI) have been established as the gold-standard therapy for postmenopausal patients. Worldwide, adjuvant denosumab at a dose of 60 mg twice per year reduces the risk of clinical fractures in postmenopausal patients with breast cancer who received AI. However, the efficacy of denosumab in the treatment of AI-associated bone loss had not been prospectively evaluated in Japan.

Background: Immediate volume replacement using a free dermal fat graft (FDFG) has been proven safe with early postoperative benefits. The aims of the present study were to clarify adequate indications and risk factors associated with operative morbidity.

Patients And Methods: A multi-institutional analysis of partial mastectomy with immediate volume replacement with FDFG was undertaken in 14 hospitals specializing in breast cancer treatment.

Recent reports have suggested that nipple-sparing mastectomy (NSM) is a potential alternative to mastectomy (MT). The aim of our study was to investigate the oncological and technical outcomes of NSM compared with MT using long-term follow-up data. A total of 932 patients between April 1985 and March 2004 were enrolled in our study.

We herein report a 75-year-old patient with recurrent hormone-nonresponsive, HER2-positive breast cancer who presented with multiple lung metastases. She had undergone a mastectomy followed by adjuvant chemotherapy with FEC, CMF, and UFT. Forty-six months after the surgery, multiple lung, liver, and bone metastases were observed.

Bone pain is one of the most common complications in cancer patients with bone metastases. Although the mechanism of cancer-associated bone pain is poorly understood, clinical observations that inhibitors of osteoclasts such as bisphosphonates (BPs) efficiently reduce bone pain suggest a potential role of osteoclasts, which play a central role in the development and progression of bone metastasis. Osteoclasts dissolve bone minerals by releasing protons through the a3 isoform of the vacuolar-H(+)-ATPase, creating acidic microenvironments.

Increased production of calcitonin gene-related peptide (CGRP) in sensory neurons is implicated in inflammatory pain. The inflammatory site is acidic due to proton release from infiltrating inflammatory cells. Acid activation of peripheral nociceptors relays pain signals to the CNS.

We report an 89-year-old patient with recurrent hormone-responsive breast cancer who presented with pleural, skin and bone metastases. Nineteen years previously, she had undergone a mastectomy and then for 16 years received adjuvant hormone therapy. The patient was orally administered a combination therapy of anastrozole, UFT and cyclophosphamide.

We report a postmenopausal recurrent breast cancer patient with triple negative disease who presented with right recurrent nerve palsy. Nine years previously, she had undergone a mastectomy. FDG-PET scan revealed neck lymph node metastases from the breast cancer.

Intervenous (IV) bisphosphonates are used for cancer patients with hypercalcemia of malignancy (HCM) and breast cancer bone metastases (BM). Recently, zoledronic acid, the most potent third generation bisphosphonate, has been approved for both HCM and BM of broad tumors. It showed 850-fold stronger activity than pamidronate in bone resorption assay, and clinical efficacy against multiple cancer bone lesion has been confirmed in randomized clinical trials.

We describe a postmenopausal woman suffering from advanced breast cancer with pleural effusion. She had prior anastrozole therapy, and was referred to our hospital with dyspnea. The use of exemestane, a highly selective steroidal aromatase inhibitor (25 mg daily), successfully induced remission of pleural effusion.

We report a case of combined large cell neuroendocrine carcinoma. A 78-year-old man with vertigo was referred to our hospital where chest X-ray revealed a tumor shadow in the right lung. A transbronchial lung biopsy specimen verified a diagnosis of non-small cell lung carcinoma (cT1N0M0).

A 50-year-old woman underwent surgical resection of a left adrenocortical carcinoma in April 2000. Bilateral pulmonary metastases and abdominal lymph node metastasis were detected in June 2001. After radiation therapy for the abdominal lymph node metastasis, a pulmonary metastatic lesion was thoracoscopically resected.

To clarify the roles of integrin and extracellular matrix (ECM) in the process of non-small cell lung cancer (NSCLC) brain metastasis, we established an in vivo model of brain metastasis of human NSCLC cell line EBC-1/original in athymic mice, and established highly brain metastatic subclone EBC-1/brain and highly bone metastatic subclone EBC-1/bone. Integrin expression of these subclones was evaluated by flow cytometry. In vitro cell attachment, migration and proliferation assays with ECMs were performed using these subclones.

Unlabelled: We investigated whether the early postoperative time course of carcinoembryonic antigen (CEA) level after resection of lung cancer could be used to predict patients' prognosis. Fifty-three lung cancer patients were included in this study. Postoperative serum CEA levels were calculated by means of non-linear least-squares fitting to the equation C(t) = (C(0)-C(p))exp(-kt) + C(p), where C(t) is postoperative CEA level, t is days after surgery, C(0) is CEA level at postoperative time 0, C(p) is CEA level at plateau, and k is the rate constant of elimination.

Long-term survival after the resection for liver metastasis from breast cancer is rare. We report on a 49-year-old woman who has been alive and well for 12 years following hepatic resection for metastatic breast cancer. Fourteen years before, the patient underwent a radical mastectomy for cancer of the right breast.

Objective: Pleurodesis using chemical agents has been applied to high-risk patients with pneumothorax. This treatment, however, is sometimes unsuccessful in patients with intractable pneumothorax. We have developed intrapleural administration of diluted fibrin glue as an effective treatment for such patients.
