BACKGROUND: Patients who have residual invasive breast cancer after receiving neoadjuvant chemotherapy plus human epidermal growth factor receptor 2 (HER2)-targeted therapy have a worse prognosis than those who have no residual cancer. Trastuzumab emtansine (T-DM1), an antibody-drug conjugate of trastuzumab and the cytotoxic agent emtansine (DM1), a maytansine derivative and microtubule inhibitor, provides benefit in patients with metastatic breast cancer that was previously treated with chemotherapy plus HER2-targeted therapy...

Guidelines from the American National Comprehensive Cancer Network recommend neoadjuvant chemotherapy to patients with locally advanced breast cancer (LABC) to downstage tumours before surgery. However, only a small fraction (15%-17%) of LABC patients achieve pathological complete response (pCR); that is, no residual tumour in the breast, after treatment. Measuring tumour response during neoadjuvant chemotherapy can potentially help physicians adapt treatment, thus potentially improving the pCR rate. Recently, imaging biomarkers that are used to measure the tumour's functional and biological features have been studied as pretreatment markers for pCR or as an indicator for intratreatment tumour response...

BACKGROUND: An increasing number of cancer patients die of cardiovascular diseases. The cardiotoxicity of chemotherapy is particularly important in triple-negative breast cancer (TNBC) with limited therapeutic options. Cardiac autophagy is an important mechanism of cardiotoxicity. This research was aimed to investigate the cardiotoxicity of chemotherapy in TNBC, screen the susceptible population, and determine the relationship between cardiotoxicity and autophagy-related polymorphisms...

BACKGROUND: Funnel chest is the most common chest deformity, occurring in 0.06-0.3% of the general population. When it occurs concomitantly with esophageal cancer, it hinders intrathoracic surgery that is necessary for treatment. Although there are a few reports of esophagectomy performed in patients with funnel chest, simultaneous treatment of esophageal cancer and funnel chest with funnel chest surgery (Nuss method) and esophagectomy has not been reported. We report the first case of advanced esophageal cancer complicated by severe funnel chest that was treated using the Nuss method and radical thoracoscopic esophagectomy...

BACKGROUND: Systemic inflammatory response (SIR) plays important roles in initiation, promotion and progression of tumor. However, the prognostic role of preoperative circulating neutrophil-lymphocyte ratio (NLR) (known as a marker of SIR) in human primary bladder cancer (BC) undergoing radical cystectomy (RC) remains controversial. Hence, we performed this meta-analysis to better understand the role of preoperative circulating NLR in prognosis prediction for primary BC patients undergoing RC...

CDK4/6 inhibitors represent a new treatment standard for hormone receptor-positive (HR+), HER2-negative advanced breast cancer (BC) patients. Although efficacious, resistance to these agents is universal. Here, we profiled a large panel of HR+ BC cell lines with conditioned resistance to the CDK4/6 inhibitor palbociclib, and analyzed cell cycle-related markers by gene expression profiles (GEP) and western blot (WB). GEP showed high molecular heterogeneity among the models, with E2F targets being significantly enriched both during treatment and at the time of resistance...

Background: MIBC is an aggressive disease, with 5-year survival rates ranging from 36 to 48% for p T3/p T4/p N+tumors. Perioperative treatment can improve overall survival, with more robust evidence in favor of neoadjuvant chemotherapy. Few randomized studies have compared neoadjuvant and adjuvant therapy in bladder cancer. Consequently, it has been difficult to establish the benefit of adjuvant chemotherapy (AC) in MIBC. Methods: Data from patients with muscle invasive bladder cancer (>pT2) collected from 2005 to 2012 within the RISC data base (Retrospective International Study of Cancers of the Urothelial Tract) were evaluated...

BACKGROUND: Neoadjuvant radio- or chemoradiation (nIRT) therapy is the standard treatment for loco-regional advanced rectal cancer patients of the lower or middle third. Currently, intensity modulated radiation therapy (IMRT) is not the recommended radiation technique even though IMRT has advantages compared to 3D-radiation regarding dose sparing to organs at risk like small bowel and urinary bladder. So far, the benefit of IMRT concerning the anal sphincter complex is not examined. With this study we intended to evaluate the dose distribution on the anal sphincters of rectal cancer patients treated with IMRT in comparison with 3D-techniques...

There is only a few of studies devoted to evaluation of pathologic response of ovarian cancer (OC) to neoadjuvant chemotherapy (NACT). Pathologic complete responses (pCR), which are characterized by the lack of viable tumor cells in surgical specimens, are rarely observed in ovarian carcinomas. Multiple reports demonstrate that pCR is associated with evidently improved disease outcomes. Recommendations of the International Collaboration on Cancer Reporting suggest to use recently developed Chemotherapy Response Scoring (CRS) system, which is based on the pathological analysis of surgically removed omental masses...

Epithelial ovarian cancer (EOC) is the leading cause of death from gynecologic malignancy and is the seventh most common cancer among women worldwide. The primary debulking surgery (PDS) followed by adjuvant chemotherapy (ACT) is a standard treatment of advanced EOC. However, there are still several limitations, such as high recurrence rate and subsequent chemoresistance. To date, many studies have reported that neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) shows non-inferior survival outcome and is associated with less postoperative morbidity compared with PDS...

Epithelial ovarian cancer (EOC) is a common malignant disease, which remains asymptomatic for a prolonged period of time and is usually diagnosed at advanced stages. Cytoreductive surgery is a backbone of EOC treatment. Wherever possible, EOC patients are subjected to primary debulking surgery (PDS) with the aim to remove all visible tumor lumps. Some patients cannot undergo PDS due to extensive disease spread and/or high risk of perioperative morbidity, therefore they are subjected to neoadjuvant chemotherapy (NACT) before the surgery...
