Recent studies have suggested inferior outcomes for elderly women with ovarian cancer. Our goal was to evaluate neoadjuvant chemotherapy versus primary cytoreduction in elderly women. »

ATP-binding Cassette (ABC) transporters are thought to cause multiple drug resistance (MDR) in various carcinomas. Gene expression data from individual transporters in ovarian cancer tissue is contradictory and also scarce for some of them. RNA levels of a panel of ABC transporters were collected and analyzed to get a more detailed overview which transporters are of importance in resistance to chemotherapeutic agents in ovarian carcinoma. »

Small-cell lung carcinoma (SCLC) is a neuroendocrine subtype of lung cancer. Although SCLC patients often initially respond to therapy, tumors nearly always recur, resulting in a 5-year survival rate of less than 10%. A mouse model has been developed based on the fact that the RB and p53 tumor suppressor genes are mutated in more than 90% of human SCLCs. »

Most non-small cell lung cancers (NSCLC) display elevated expression of epidermal growth factor receptor (EGFR), but response to EGFR kinase inhibitors is predominantly limited to NSCLC harboring EGFR-activating mutations. These mutations are associated with increased activity of survival pathways, including phosphatidylinositol 3-kinase/AKT and signal transducer and activator of transcription 3/5. »

Surgery for non-small cell lung cancer (NSCLC) is associated with a significant negative impact on health-related quality of life (HRQoL), but only a few published studies evaluate the long-term HRQoL and its association with preoperative pulmonary function tests (PFTs). »

The polymorphism of cytochrome P4501B1 (CYP1B1) codon 432 (rs1056836, CYP1B1*3, or Leu432Val) is thought to have a significant effect on lung cancer risk, but the results are inconsistent. In this meta-analysis, we assessed 9 published studies involving 6501 subjects that investigated the association between the CYP1B1 codon 432 polymorphism and risk of lung cancer. »

Immunotherapy, particularly the adoptive cell transfer (ACT) of tumor-infiltrating lymphocytes (TIL), is a very promising therapy for metastatic melanoma. Some patients unable to receive TIL have been successfully treated with autologous peripheral blood lymphocytes (PBL), genetically modified to express human leukocyte antigen (HLA) class I antigen-restricted, melanoma antigen-reactive T-cell receptors; however, substantial numbers of patients remain ineligible due to the lack of expression of the restricting HLA class I allele. »

We investigated whether elevation in serum cytomegalovirus (CMV) or Epstein-Barr virus (EBV) immunoglobulin G (IgG) antibody levels precedes the development of breast cancer. »

Gene expression signatures for a basal-like breast cancer (BLBC) subtype have been associated with poor clinical outcomes, but a molecular basis for this disease remains unclear. »

Pituitary tumor transforming gene (PTTG) binding factor (PBF; PTTG1IP) is a relatively uncharacterized oncoprotein whose function remains obscure. Because of the presence of putative estrogen response elements (ERE) in its promoter, we assessed PBF regulation by estrogen. PBF mRNA and protein expression were induced by both diethylstilbestrol and 17beta-estradiol in estrogen receptor alpha (ERalpha)-positive MCF-7 cells. »
