  • Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous neoplasms with overall increasing incidence, but not an associated increase in survival rate over the past few decades. Tumors originate from at least 16 different cells of diffuse endocrine system (DES), scattered through mucosa of gastrointestinal tract. They are mainly sporadic, but sometimes exhibit familial inheritance.

  • Few studies have simultaneously investigated the role of soluble tumor necrosis factor a (TNFa ) receptors types 1 and 2 (sTNF-R1 and sTNF-R2), C-reactive protein, and interleukin-6 as predictors of cardiovascular events. The value of these inflammatory markers as independent predictors remains controversial.

  • Colorectal cancer (CRC) is a major public health issue worldwide, and novel tumor markers may contribute to its efficient management by helping in early detection, prognosis or surveillance of disease. The aim of our study was to identify new serum biomarkers for CRC, and we followed a phased biomarker discovery and validation process to obtain an accurate preliminary assessment of potential clinical utility.

  • PSA (prostate-specific antigen), the most useful serum marker for prostate cancer, is encoded by thehKLK3gene and is present in the serumas amixture of several molecular species. This work was performed to identify the hKLK3 transcripts in order to determine how many proteins resembling PSA are synthesized from thehKLK3gene and secreted in blood. Combined Northern blotting, molecular cloninganddatabase searching showed that thehKLK3gene produces at least 15 transcripts ranging in size from 0.7 to 6.1 kb. Polysomal distribution analysis revealed that the transcripts shorter than 3.

  • Recent advances in clinical proteomics have propelled us into an exciting period of discovery of new cancer biomarkers, although the available proteomic technologies have their limitations. The principles of proteomic technology require stringent guidelines for the collection of clinical material, the application of analytical techniques, and for our interpretation of the data. In this review, we present an overview of the serum tumor markers in current use.

  • Clinical course of CLL is variable. Recently, progress has been made in the identification of biological markers that could predict disease progression. Particularly, the expression of unmutated Ig genes, some cytogenetic abnormalities like 17p and 11q deletions and the expression of the zeta-associated protein 70 (ZAP-70) are associated to a poor prognosis.

  • The all-too-common conditions this woman and her children face illustrate how health programs and weak systems in many developing countries are not meeting needs. Although health services may be available, too often they are of poor quality and are provided in an uncoordinated or ad hoc manner. Often, they are organized around funding sources or diseases, rather than in a way that addresses the broader needs of the populations they seek to serve.

  • Breast cancer remains a leading cause of cancer death among women in the United States. More than 180,000 new cases of invasive breast cancer are diagnosed each year, and more than 40,000 women die of the disease. Recent years, however, have seen improvements in survival attributed to better treatment and earlier diagnosis. Research efforts have been directed toward better treatment, preventive strategies, and early detection.

  • Endometrial, cervical, and ovarian cancers are the three most common malignancies of the female reproductive tract. In the United States alone, roughly 12,000 women are diagnosed with uterine cervical cancer annually, and 4,000 will die from the disease [1]. The relatively low incidence of cervical cancer in the US is largely attributable to the effectiveness of Papanicolaou’s cytological cervical screening test (the Pap test).

  • Tumor markers may be useful in patient management in certain tumors. Response to therapy may be difficult to gauge with certainty. However, some tumors produce or elicit the production of markers that can be measured in the serum or urine and, in a particular patient, rising and falling levels of the marker are usually associated with increasing or decreasing tumor burden, respectively. Some clinically useful tumor markers are shown in Table 77-5.

  • Tumor Markers Careful monitoring of the serum tumor markers AFP and hCG is essential in the management of patients with GCT, as these markers are important for diagnosis, as prognostic indicators, in monitoring treatment response, and in the detection of early relapse. Approximately 70% of patients presenting with disseminated nonseminomatous GCT have increased serum concentrations of AFP and/or hCG. While hCG concentrations may be increased in patients with either nonseminoma or seminoma histology, the AFP concentration is increased only in patients with nonseminoma.
