Alteration of biomarkers is well-documented in breast cancer at locoregional recurrence or metastasis attributed to tumor heterogeneity and change in biology. There is a lack of literature on alteration of biomarkers in metastatic breast cancer (MBC) at progression. We included 32 patients of upfront MBC. Estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2/neu documented at baseline and at progression. Median age was 46 (range 26-72) years. Estrogen receptor altered in 6 (18...

Alteration of expression of the tumor suppressor gene BRCA-1 has been widely studied in breast and ovarian carcinoma. However, pattern of this alteration in the benign-borderline-carcinoma sequence in serous and mucinous ovarian neoplasms have not yet fully described. Tissue sections from 214 formalin-fixed paraffin-embedded ovarian specimens were stained immunohistochemically with BRCA-1 antibody. Specimens were 10 normal ovarian surface epithelium, 10 fallopian tube epithelium, 70 benign adenoma (50 serous and 20 mucinous), 28 borderline (13 serous and 15 mucinous), 78 carcinoma (58 serous and 20 mucinous), and 18 metastatic deposit (13 serous and 5 mucinous)...

Pleural effusion is a common presenting feature of malignancy. Malignant pleural effusion is primarily diagnosed by pleural fluid cytology, pleural biopsy, and tumor markers. The glycoprotein YKL-40 is a new tumor marker that has shown to have a good diagnostic accuracy to detect malignant pleural effusion. However, there are only a few studies that have evaluated pleural fluid YKL-40 for detecting malignant pleural effusions. Hence, we conducted this study to evaluate the utility of pleural fluid YKL-40 to detect malignant pleural effusion...

Until a recent introduction to checkpoint inhibitors, there were limited second-line chemotherapy options for urothelial carcinoma (UC) patients with disease progression after first-line, platinum-based treatment. Outcomes for patients with advanced disease over the past 30 years have highlighted a need for new and better therapy. In response to evolving interest, durvalumab (MEDI4736) was introduced as a potential treatment for advanced stages of UC. Durvalumab is a selective, high-affinity, human IgG1 kappa monoclonal antibody engineered with a triple mutation to reduce toxicity...

Although several published studies have investigated the association between p53 Arg72Pro polymorphism and the risk of colorectal cancer (CRC), their results have been ambiguous. To examine the overall relationship between published case-control studies of Asian subjects, we conducted a meta-analysis based on 13 studies. Databases PubMed, EMBASE, Web of Knowledge, and the Chinese National Knowledge Infrastructure were screened for studies carried out up to November 1, 2017. To evaluating the association, crude odds ratios (ORs) with 95% confidence intervals (95% CI) were calculated...

Osteosarcoma (OS) is a common malignant tumor of bone, of which clear understanding of molecular pathologic process is not yet possible. Insulin-like growth factor-1 (IGF-1) is a hormone that plays vital role in development and function of many tissues. Unfortunately, IGF-1 and its receptor (IGF-1R)'s over-expression have been implicated in carcinogenesis, and indicated to constitute a risk factor for the development of multiple human cancers, including OS. Increased levels of IGF-1 and IGF-1R have been reported in OS, leading to cancer progression through transformation, proliferation, pro-metastasis, and decreased susceptibility to apoptosis...

According to lung cancer guidelines, positron emission tomography scan is recommended for initial evaluation of bone metastasis. However, guidelines differ in their recommendations for when it should be used. We investigated the appropriate use of bone imaging in nonsmall cell lung cancer (NSCLC) patients. One hundred seventy-seven consecutive NSCLC patients who had distant metastases at presentation and were admitted between January 2012 and April 2016 were retrospectively reviewed. Among patients with bone metastases, we explored bone pain, number of bone metastases, location of bone metastases, and clinical tumor (T) and lymph node (N) classification...

REVIEW
Anthony E Rizzo, Sarah Feldman
In the coming decade, primary testing for human papillomavirus (HPV) will likely become the standard of care for cervical cancer screening in both low- and high-resource settings. This change comes as evidence has accumulated to support HPV testing as more sensitive to detect high-grade precancerous disease. Furthermore, negative HPV testing has demonstrated a lower cumulative incidence of cervical intraepithelial neoplasia (CIN) grade 3 or worse pathology (CIN3+) when compared to negative "Pap smears" over several rounds of screening...

Colorectal cancer (CRC) is the third most common cancer worldwide, with a global incidence of over 1 million cases. In the era of personalized medicine, tumor sampling is essential for characterizing the molecular profile of individual tumors. This provides pivotal information regarding optimal sequencing of therapy and emergence of drug resistance, allowing for timely therapy adjustment. However, tumor tissue sampling offers static information in a single time point and area of disease at the time of biopsy, which may not entirely represent the heterogeneity of molecular alterations...
