Cause and clinical outcome of portal vein thrombosis

Among the 118 patients with portal vein thrombosis, noncirrhotic and nontumoral extrahepatic portal vein obstruction are young and present with well tolerated bleed.

New gene findings show that controls of lifespan and cancer have deep, common roots

A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm.

Breast cancer radiation does not affect women's immune system

A new study shows that neither of two commonly used radiation treatments for early-stage, node-negative breast cancer has any effect on a woman's immune system, even though women who receive five-day partial-breast radiation therapy (MammoSite brachytherapy) (PBRT) have improved energy and quality of life compared to women who undergo six weeks of whole-breast radiation therapy (WBRT).

AMDL submits data to FDA for clearance to market its diagnostic test to monitor colorectal cancer patients

AMDL, Inc., developer and marketer of tests for the early detection of cancer and other serious diseases, announced today that it has filed with the U.S. Food & Drug Administration (FDA) for clearance to market its unique, proprietary DR-70 (FDP) ELISA tumor marker test for use as an aid in monitoring patients previously diagnosed with colorectal cancer. AMDL used the guidance provided at the meeting they had with the FDA on January 25, 2007.

New research may show why some prostate cancer recurs after treatment

Cancer researchers have long worked to understand why some prostate cancers recur after the use of therapies designed to stop the production of testosterone and other androgens that fuel cancer cell growth.

A tumor-blocking protein may be key in developing deadly form of pancreatic cancer

A tumor-blocking protein previously implicated in prostate and breast cancer development may also be behind the most aggressive type of pancreatic cancer. Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have discovered that the protein pp32 – which normally applies the brakes on a cancer-causing gene – is missing in an aggressive form of pancreatic cancer.

Breast cancer awareness calls for cardiovascular awareness

Women who overcome breast cancer have every reason to celebrate. But a heart filled with joy may also be a heart damaged by life-saving cancer therapies, a growing body of research shows.

Analysis of breast and colon cancer genes finds 5,000 previously unmapped genes

Researchers from University Hospitals (UH) Ireland Cancer Center and Case Western Reserve University School of Medicine are part of a new national study that has analyzed more than 18,000 genes, including 5,000 previously unmapped genes, from breast and colorectal tumors.

Research shows how stem cells decide to become either skeletal or smooth muscle

Researchers have discovered a key protein that controls how stem cells "choose" to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).

Better understanding of environmental influences on the aging process of stem cells

A stem cells' immediate neighborhood, a specialized environment also known as the stem cell niche, provides crucial support needed for stem cell maintenance.

Mouse mammary tumor virus might be involved in causing human breast cancer

Mouse mammary tumor virus (MMTV) - which causes mammary cancer in mice - can replicate and spread in human cells, research published this week shows.

HER-2 status predicts success of chemotherapy in breast cancer treatment

Researchers have found they can potentially target chemotherapy for breast cancer to only those women most likely to benefit, sparing the majority of patients from unnecessary side effects.

Cancer conflict with adjuvant chemotherapy

Women under the age of forty with breast cancer who are given drugs in addition to lumpectomies or radiotherapy, known as adjuvant chemotherapy, may not be benefiting from these drugs.

Trial results of lovaxin C in advanced cervical cancer patients

A first-in-man trial of a live Listeria vaccine was reported by Advaxis Inc. The Phase I/II trial was testing Lovaxin C in advanced cervical cancer patients.

Androgen deprivation therapy linked to increased risk of heart disease death

The use of androgen deprivation therapy to treat localized prostate cancer is associated with an increased risk of death from heart disease, according to a study published online October 9 in the Journal of the National Cancer Institute .

Network approach finds potential breast cancer susceptibility gene

Like a crossword-puzzle solver who uses the letters in some answers to figure out others, researchers at Dana-Farber Cancer Institute and an international group of collaborators have used data on genes involved in inherited forms of breast cancer to identify a gene linked to non-hereditary cases of the disease.

M-POSSUM evaluation system improves accuracy and effectiveness of the original system

Based on POSSUM, a system suggested by some British scholars more than 10 years ago, a team led by Dr. Lian-An Ding has established the M-POSSUM evaluation system with the aim of improving the accuracy and effectiveness of the original system.

Interleukin-8, key marker for colorectal cancer treatment

Colorectal cancer (CRC) is currently one of the three most frequent malignancies in Western industrial nations.

Tiny radioactive molecules provide novel way to fight colorectal cancer

Johns Hopkins scientists have developed a potentially novel way to fight colorectal cancer using tiny molecules to deliver potent barrages of radiation inside cancer cells, unlike current treatments that bind to the surface of cells and attack from the outside and cause unwanted side effects.

African-American women less likely to have adjuvant cancer therapy than white women

A new study finds that white women more frequently take more of the life-prolonging supplemental therapies used to treat breast cancer than African-American women.
