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

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...

BACKGROUND: Cardiac events are the most common nonmalignant cause of death in childhood cancer survivors. This population has an increased risk of morbimortality, probably secondary to the treatment side effects. The objective was to determine the prevalence and determinants of left ventricular dysfunction in a cohort of long term childhood acute leukemia survivors treated with potentially cardiotoxic therapies. METHODS: Retrospective study with at least 10 years of follow-up, diagnosed between 1999 and 2003...

Breast cancer is the most common malignancy in females. The common site for metastases is bone, lungs, liver, and regional lymph nodes. Larynx as a metastatic site from breast cancer is extremely rare. The authors report a 63-year-old female treated for carcinoma of right breast 5 years back who presented with hoarseness of voice. Clinicoradiological examination revealed a soft tissue lesion in larynx. Pathological evaluation of the laryngeal lesion revealed metastases secondary to breast cancer. The patient received systemic chemotherapy and local radiotherapy...

Lung cancer is the most common cause of cancer death worldwide. Treatment for lung cancer has become increasingly more complex over the last several years. Immune checkpoint inhibitors have dramatically changed the treatment landscape of advanced nonsmall cell lung cancer (NSCLC). There are currently 3 approved checkpoint inhibitors for patients with NSCLC who progressed after platinum-doublet chemotherapy (Pembrolizumab and /or Nivolumab and /or Atezolizumab). Avelumab and durvalumab are currently under investigation in phase 3 trials...

PURPOSE: Breast cancer classifies to 4 major subgroups according to immunohistochemistry staining features as Luminal A, Luminal B, human epidermal growth factor receptor 2 overexpression, and Triple Negative. Cancer Antigen15-3 (CA15-3) is used as a tumor marker in breast cancer while its value in early stage and in breast cancer subgroups is still controversial. In this study, we aimed to investigate that whether it is or not differences of the serum preoperative CA15-3 levels in early breast cancer subgroups...

PURPOSE: Lung cancer is the leading cause of cancer death worldwide, and the predominant risk factor for its development is smoking. Thymidylate synthase (TYMS) is a key enzyme in DNA synthesis that catalyzes the conversion of deoxyuridine monophosphate to dTMP. Rs931794, a single nucleotide polymorphism located in the TYMS gene, was suggested to be associated with cancer risk. METHODS: To analyze the interaction between rs3819102 and environmental factors on the risk of lung cancer in a Chinese population, single nucleotide polymorphismscan was used to genotype this polymorphism in 974 lung cancer cases and 1005 control subjects...

The risk of recurrence from stage II colon cancer and benefit from adjuvant chemotherapy is influenced significantly by the molecular marker termed microsatellite instability and/or mismatch repair (MMR) gene product expression.1 Study results and the National Comprehensive Cancer Network Colon Cancer Guideline panel suggest that adjuvant chemotherapy (fluoropyrimidine [5-FU] +/- oxaliplatin) be considered for patients with stage II colon adenocarcinoma harboring one or more "high-risk" features.2 However, for patients with deficient-MMR (dMMR) stage II colon cancer, evidence suggests there may be a detrimental effect with adjuvant 5-FU alone...

PURPOSE: Solid pseudopapillary neoplasm (SPN) is a rare, low-grade neoplasm with excellent prognosis. In this study, we evaluated clinicopathological characteristics of patients diagnosed with SPN retrospectively. METHODS: This is a retrospective study intended to characterize patients with the diagnosis of SPN between 2005 and 2015. Clinicopathological features, recurrence rate, and overall survival of 28 patients were recorded. Malignant SPN criteria were defined as the presence of distant metastasis (developed at diagnosis or during follow up) or lymph node involvement...

Despite advances in the treatment of metastatic colorectal cancer (CRC) the 5-year survival of patients with this disease remains low. A small proportion of CRCs overexpress the HER2 oncogene and the effective targeting of this pathway in other malignancies such as breast and gastric cancer has led to efforts to determine if it can also be exploited as a target in CRC. Activation of the HER2 pathway as a bypass signalling pathway has been identified as a mechanism of resistance for antiepidermal growth factor receptor antibody therapy in both the first line and salvage settings...
