Objective: To investigate whether texture analysis based on contrast-enhanced MRI can predict pathological complete response of locally advanced breast cancer undergoing neoadjuvant chemotherapy(NAC). Methods: Forty-seven patients with breast cancer undergone neoadjuvant chemotherapy from January 2015 to February 2016 were divided into pathological complete response (pCR) group or non-pathological complete response (non-pCR) group based on surgical pathology. Their parameters of texture analysis based on MRI before neoadjuvant chemotherapy and after 2 cycles of treatment were analyzed...

RATIONALE AND OBJECTIVES: We present an optical mammography study that aims to develop quantitative measures of pathologic response to neoadjuvant chemotherapy (NAC) in patients with breast cancer. Such quantitative measures are based on the concentrations of oxyhemoglobin ([HbO2]), deoxyhemoglobin ([Hb]), total hemoglobin ([HbT]), and hemoglobin saturation (SO2) in breast tissue at the tumor location and at sequential time points during chemotherapy. MATERIALS AND METHODS: Continuous-wave, spectrally resolved optical mammography was performed in transmission and parallel-plate geometry on 10 patients before treatment initiation and at each NAC administration (mean number of optical mammography sessions: 12, range: 7-18)...

Background and objective Lung cancer is the leading form of cancer in terms of both incidence and cancer-related deaths. For patients with resectable IIIa/N2 non-small cell lung cancer (NSCLC), guidelines in and abroad recommend multidisciplinary team treatment, including surgery and chemotherapy, radiotherapy or other comprehensive treatment. Newly published evidences prove that neoadjuvant therapy can improve outcomes of NSCLC patients significantly, with advangtages in tolerability and compliance medication...

Non-small cell lung cancer (NSCLC) is the most common cause of cancer mortality. Although a significant proportion of patients can be cured with surgery, with or without adjuvant or neoadjuvant chemotherapy and radiation, a significant proportion of patients will fail, particularly distantly. Over fifty percent of patients present with stage IV disease. There are multiple forms of immunotherapy available including T-cell transfer, cytokine therapy, and oncolytic viruses. Checkpoint inhibitors have shown tremendous activity in NSCLC and are currently under intense study given promising data on response...

BACKGROUND: A relationship between baseline tumor-infiltrating lymphocytes (TIL) and outcomes has been described in HER2-positive breast cancer. Nevertheless, the magnitude of this association and whether this effect differs based on the type of anti-HER2 agent remain controversial. This meta-analysis investigated the association between baseline TIL and pathologic complete response (pCR) rates in HER2-positive breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab and lapatinib either alone or in combination...

Primary neuroendocrine tumors (NETs) of the mediastinum are very rare. Prognosis is usually poor despite treatment options. We present the case of a primary atypical carcinoid tumor of the mediastinum successfully treated by multimodal approach. A 50-year-old man presented for asthenia, dyspnea, and substernal sense of weight for two weeks. A chest-CT scan revealed a tumor mass of 107×55×95 mm(3) localized in the anterosuperior mediastinum compressing both brachiocephalic veins, the superior vena cava, the pericardium, and lungs...

Purpose: Determination of microsatellite instability (MSI) by PCR is the gold standard; however, immunohistochemistry (IHC) of mismatch repair (MMR) proteins is frequently performed instead. The reliability of these methods on post-neoadjuvant-therapy specimens is unknown.  We examined the effect of neoadjuvant therapy on MSI results by PCR and IHC. Experimental design: A total of 239 colorectal cancers resected after neoadjuvant therapy were assessed for MSI with PCR and IHC. PCR and IHC results for matched paired pre- and post-treatment specimens were compared...

Preoperative systemic inflammatory response is associated with a poor long-term prognosis following resection surgery for malignant tumors. Several markers of systemic inflammation have been reported to be associated with the outcome; however, they have not currently been fully investigated. Therefore, the association between preoperative peripheral blood neutrophil count and oncological outcome following hepatic resection for colorectal liver metastasis (CRLM) was retrospectively investigated. The present study comprised 89 patients who had undergone hepatic resection for CRLM between January 2000 and March 2010...

Lisa A Newman
Treatment of early-stage invasive breast cancer with breast-conserving surgery plus radiation therapy (RT) yields overall survival outcomes equivalent to those achieved with mastectomy. Further, breast-conserving surgery is endorsed by the National Comprehensive Cancer Network as being supported by the highest-level, category 1 evidence. Advances in pathologic evaluation, management of multiple tumors, oncoplastic lumpectomy techniques, neoadjuvant chemotherapy, and hypofractionated RT can expand the pool of patients eligible for breast-conserving surgery...
