Cancer cells do not grow equally well everywhere in the body. Often, they first create the conditions in which they can grow. Many years ago researchers discovered that solid tumors attract blood vessels to ensure their supply of nutrients by secreting specific factors. Now the immunologist Dr. Uta Höpken (Tumor and Immunogenetics Research Group at the Max Delbrck Center for Molecular Medicine, MDC, Berlin-Buch in the Helmholtz Association) and the hematologist Dr. Armin Rehm...

Scientists close in on molecular moves that let tumor cells act as stowaways in lymphatic system Cancer has a mighty big bag of tricks that it uses to evade the body's natural defense mechanisms and proliferate. Among those tricks is one that allows tumor cells to turn the intricate and extensive system of lymphatic vessels into something of a highway to metastasis. Yet research unveiled this week may aid in the development of therapeutics that will put the brakes on such cancer spread, and...

ST. LOUIS, April 8, 2011 /PRNewswire-USNewswire/ -- Saint Louis University researchers have identified a novel mechanism to control the traffic of cells and fluid from tissues to lymphatic vessels. It may be possible to harness this mechanism to fight cancer spread from one organ to another organ and improve the effectiveness of vaccines. The lymphatic system is an extensive fluid transit system, consisting of vessels in the body. It defends the body against infection. Cancer cells and...

(Ivanhoe Newswire)  A new laser technique could help prevent cancer from spreading in humans. In the study, Dr. Tuomas Tammela and his colleagues at the University of Helsinki, Finland, wanted to find out if they could help stop a cancer from spreading by using a laser therapy to destroy cancer cells lodged in lymphatic vessels. The scientists experimented with PDT Photodynamic therapy (PDT). During PDT doctors inject a light-activated drug into the tumors and then turn an infrared laser...

Photodynamic ablation of lymphatic vessels and intralymphatic cancer cells prevents metastasis Tumor cells have several routes that enable them to move from the primary tumor to distant tissues, a process called metastasis. It is metastasis of the primary tumor that kills most cancer patients. One of the least studied routes of metastasis is the lymphatic system. Many tumors produce factors that promote the formation of new lymphatic vessels (lymphangiogenesis). The newly formed lymphatic...

Among patients with early-stage breast cancer that had spread to a nearby lymph node and who received treatment that included lumpectomy and radiation therapy, women who just had the sentinel lymph node removed (the first lymph node to which cancer is likely to spread from the primary tumor) did not have worse survival than women who had more extensive axillary lymph node dissection (surgery to remove lymph nodes found in the armpit), according to a study in the February 9 issue of JAMA....

Process yields higher throughput; quicker, more-consistent diagnoses Researchers are leveraging Ohio Supercomputer Center resources to develop computer-assisted diagnosis tools that will provide pathologists grading Follicular Lymphoma samples with quicker, more consistently accurate diagnoses. "The advent of digital whole-slide scanners in recent years has spurred a revolution in imaging technology for histopathology," according to Metin N. Gurcan, Ph.D., an associate professor of Biomedical...

With guidance from a specialized scan, radiation oncologists at Mayo Clinic were able to reduce by 55 percent the number of lymph nodes critical for removing fluid from the arm that received damaging radiation doses. The researchers report that integrating single photon emission computed tomography (SPECT) with the computerized tomography (CT) scans utilized for breast cancer radiotherapy planning may offer patients substantial protection against lymphedema, an incurable, chronic swelling of...

Potential mechanism identified In research to be presented at the American Society of Hematology (ASH) annual meeting, investigators at Dana-Farber Cancer Institute in Boston offer a new explanation of why chronic lymphocytic leukemia (CLL) tends to recur in the lymph nodes and bone marrow after being cleared from the bloodstream by chemotherapy. Their findings will be reported during in an oral session on Monday, Dec. 6, at 4:45 p.m. in room 315 of the Orange County Convention Center. To...

Breast cancer, one of the most prevalent cancers in women, afflicts an additional 200,000 women each year and causes about 40,000 deaths annually. The disease often extends to neighboring lymph nodes, in part, through lymphovascular invasion (LVI)"”a process in which cancer cells invade blood vessels or the lymphatic system"”and can often translate into a poor prognosis for patients. Some scientists argue that evidence of LVI does not necessarily mean that the disease will recur...

A lymph node is an immune system organ that is widely distributed throughout various places in the body. There are about 500-600 nodes in an individual adult, with clusters of lymph nodes found in the underarms, groin, neck, chest, and abdomen. The lymphatic system as a whole is responsible for acting as the body’s primary mechanism of defense. Each node is oval-shaped, and measures between a few millimeters and a few centimeters long. They are linked to one another by lymphatic vessels and...
