BACKGROUND: Rates of mastectomy for breast cancer treatment and immediate reconstruction continue to rise. With increasing scrutiny on outcomes and patient satisfaction, there is an impetus for providers to be more deliberate in deciding appropriate patient selection for breast reconstruction. The Breast Reconstruction Risk Assessment (BRA) Score was developed for prediction of complications after primary prosthetic breast reconstruction, focusing on calculating risk estimations for a variety of complications based on individual patient demographics and perioperative characteristics...

PURPOSE: To investigate whether a history of non-muscle-invasive bladder cancer (NMIBC) plays a prognostic role in patients with muscle-invasive bladder cancer (MIBC) treated with radical cystectomy in the era when neoadjuvant chemotherapy was established as standard therapy for MIBC. PATIENTS AND METHODS: A total of 282 patients who were diagnosed with cT2-T4aN0M0 bladder cancer treated with open radical cystectomy at our institutions were included. Initially diagnosed MIBC without a history of NMIBC was defined as primary MIBC group (n = 231), and MIBC that progressed from NMIBC was defined as progressive MIBC (n = 51)...

OBJECTIVES: In case of large breast cancer, neoadjuvant chemotherapy (NAC) can be performed to reduce the size of the tumor and thus perform a conservative surgery. The place of the sentinel lymph node biopsy (SLNB) in case of NAC is still debated. The main aim of this study is to assess the risk of axillary recurrence after negative SLNB before NAC. METHODS: It is a retrospective, observational and uni-centric study. We included 18 to 80-year-old patients with unilateral breast cancer requiring a NAC and with a negative SLNB before NAC...

We undertook a systematic evaluation of the prognostic value of numerous histologic factors in 165 radical cystectomies (RC) of patients with invasive urothelial carcinoma who underwent surgery after neoadjuvant chemotherapy (NAC). Tumor regression grade (TRG) and therapy-related stromal and epithelial changes were also recorded. Locally advanced disease (≥pT2 and/or pN+) was present in 64% of patients, 22% had no evidence of residual carcinoma (pT0+pN0) and 28% had no evidence of residual muscle invasive carcinoma (≤pT1+N0)...

Osteosarcoma is an aggressive malignancy that usually occurs in children and young adults, and long-term survival is only about 20% in patients with metastasis or recurrent disease. Traditional non-invasive techniques, such as positron-emission tomography (PET) scanning, magnetic resonance imaging (MRI) or computed tomography (CT) scanning, may not identify single lesions in the early stage or accurately detect small lesions. A novel technique, positron emission tomography/computed tomography (PET/CT), which is widely used in clinical practice, shows more accuracy, sensitivity, and specificity in the diagnosis of osteosarcoma...

Surgery represents the only chance of cure for patients with gastroesophageal adenocarcinoma; however surgery alone does not cure most patients. Over the past decade, several multimodality adjunctive treatments have improved survival for patients with operable gastroesophageal adenocarcinoma who are undergoing surgical resection; these include peri-operative chemotherapy, neoadjuvant chemoradiotherapy, adjuvant chemotherapy and adjuvant chemoradiotherapy. More recently, the results of several large randomised trials are leading to a shift in the peri-operative treatment of gastroesophageal cancer, away from anthracycline-based and towards taxane-based chemotherapy regimens...

BACKGROUND: Radical resection by multivisceral resection of colorectal T4 tumours is important to reduce local recurrence and improve survival. Oncological safety of laparoscopic resection of T4 tumours is controversial. However, robot-assisted resections might have advantages, such as 3D view and greater range of motion of instruments. The aim of this study is to evaluate the initial results of robot-assisted resection of T4 rectal and distal sigmoid tumours. METHODS: This is a cohort study of a prospectively kept database of all robot-assisted rectal and sigmoid resections between 2012 and 2017...

Background: Metaplastic breast cancer (MBC), characterized by admixed epithelial, squamous or mesenchymal elements, constitutes <1% of breast cancers and has a poor prognosis but a paradoxically low reported rate of axillary lymph node (LN) involvement. Due to its rarity, data on appropriate axillary management is lacking, prompting this investigation of LN status and outcomes. Methods: We identified 41 MBC patients treated at our institution 2001-2011 who were followed for a median of 66 months...

BACKGROUND: Neoadjuvant chemotherapy (NAC) increases breast conservation rates in patients with resectable breast cancer at the associated cost of higher locoregional recurrence rates; however, the magnitude of the survival benefits of NAC for these patients remains undefined. Therefore, we aimed to clarify the survival benefit of NAC versus postoperative chemotherapy by conducting an updated meta-analysis of randomized clinical trials (RCTs). METHODS: The authors searched the Cochrane Library, PubMed, Embase, Web of Science, Chinese biomedical literature database, and Chinese Scientific Journals full-text database from their inception to December 2016...

Platinum-resistant recurrent ovarian cancer has a poor prognosis, but combined therapy with bevacizumab and anticancer agents may be useful. We report a patient with long-term disease control by the combination of bevacizumab and gemcitabine (BEV + GEM). The patient was a 77-year-old woman with high-grade Stage IIIC serous ovarian carcinoma. In 2012, a complete response (CR) was obtained by neoadjuvant and adjuvant chemotherapy using paclitaxel plus carboplatin and tumor debulking surgery. After recurrence in 2013, CR was achieved again with gemcitabine plus carboplatin...
