Gene therapy with a T cell receptor targeting a single cancer-specific point mutation is being used to eradicate large solid tumors.

Potential Drug Targets Are Identified With Finding That Genes in the Ly6 Gene Family Drive Tumorigenesis and Poor Prognosis

By

Lower patient survival and worse clinical outcomes across a variety of cancer types were correlated with increased expression of 4 genes in the Ly6 gene family. These findings came from an analysis of 130 gene expression studies from 10 solid cancers.

Liquid Biopsy Provides A More Comprehensive View of Genetic Changes Occurring in Cancer Tumors

By

Analyzing tumor DNA fragments in the bloodstream, known as circulating tumor DNA (ctDNA), may offer a more complete view of a patient's cancer from a molecular perspective.

Optical Probes That Illuminate Solid Tumors in Surgery Move One Step Closer to Reality

Optical Probes That Illuminate Solid Tumors in Surgery Move One Step Closer to Reality

By

Optical probes that make cancer cells glow and improve surgical tumor removal are in phase I and II clinical trials in humans. The probes could be commonplace in the next 5 to 10 years, hypothesize the researchers.

Early Trial Results Show Novel Injectable Enables Complete Visualization for Resection of Tumors

Early Trial Results Show Novel Injectable Enables Complete Visualization for Resection of Tumors

By

A new injectable agent causes cancer cells in a tumor to fluoresce, potentially enabling surgeons to locate and remove all of a cancerous tumor on the first attempt.

Extra Biopsies in Clinical Trials Often Have No Impact on Drug Dose or Use in Cancer Treatments

By

Extra biopsies performed solely to study the pharmacodynamics of a new anticancer drug have no impact on subsequent drug development or on how physicians use these new drugs to treat future patients.

Mix of Cell Types in Cancer Tumor Samples May Bias Genomic Analyses

By

Genetic analyses and other tests performed by both researchers and physicians can be significantly skewed when normal cells, especially immune cells, are intermixed with cancerous cells in a tissue sample.

Identifying Genetic Drivers of Breast Cancer Tumors and Metastasis

Identifying Genetic Drivers of Breast Cancer Tumors and Metastasis

By

A novel genetic driver analysis of matched breast cancer primary tumors and multiorgan metastases suggests that most genetic drivers in a single tumor are based on DNA copy number variants (CNV), are established early, and are maintained in metastases. These findings were presented at the 2015 San Antonio Breast Cancer Symposium.

Mathematical Modeling Can Help Predict Impact of Surgery on Cancer Metastasis

By

The size of a surgically removed tumor is generally thought to relate to the risk of metastasis; however, tumor cells metastasize at different times therefore the rate of spread is difficult to assess. A mathematical model was developed to calculate the relationship between tumor size and the relative risk of recurrence after surgery.

Using MRI to Follow Magnetic Nanoparticles Predicts Effectiveness of Response to Nanotherapeutics

An FDA-approved, magnetic nanoparticle and MRI identifies tumors most likely to respond to drugs delivered via nanoparticles.

Tumors May Seed Cancer Metastases Earlier Than Expected

By

A new study has found an additional mechanism explaining how EGFR, a molecule long linked to cancer progression appears, to seed the body with metastatic cells long before doctors would typically detect a primary tumor.

Laser-Based Tool Could Increase Accuracy and Safety of Brain Tumor Surgery

By

A new laser-based microscope technology may help surgeons see the difference between tumor tissue and normal brain tissue in real-time.

Childhood Brain Tumors Affect Working Memory of Adult Survivors

By

Adult survivors of childhood brain tumors have lower working memory performance compared with healthy adults, according to research from Georgia State University and Emory University, in Atlanta.

Surgical Probe Distinguishes Between Tumor Margins and Healthy Tissue

By

A new surgical tool that uses light to ensure surgeons removed all of a cancerous tumor was found to correlate well with traditional pathologists' diagnoses, according to a clinical study showing that the tool could soon enable reliable, real-time surgical guidance.

Exercise slows tumor growth and improves chemotherapy

Exercise slows tumor growth and improves chemotherapy

By

A new study of the impact of exercise in models of breast cancer in mice has shown the benefits of exercise on the function of blood vessels around tumors.

New sequencing technique reveals genetic clues to rare breast tumors

By

A recent study provides a comprehensive analysis of the molecular alterations at work in phyllodes tumors, a rare type of breast tumor.

Response to new drug in patients with lymphomas and advanced solid tumors

Patients with B-cell non-Hodgkin lymphomas and advanced solid tumors have responded to a new drug that is being tested for the first time in humans in a phase I clinical trial.

Tumor-analysis technology speeds treatment decisions for colorectal cancer

By

A novel medical-imaging technology, TexRAD, which analyzes the texture of tumors, has been shown in trials to enable early diagnosis of colorectal cancer in patients not responding to the standard cancer therapy better than other available tumor markers.

Collaboration yields new methods to treat tumors with antennas

By

Two engineering researchers have challenged a commonly held idea about tumor ablation.

Cytokine therapy enhances natural killer cell functions against tumor cells

By

Cytokine therapy enhances the activity of natural killer (NK) cells against tumors that lack the cell surface protein known as MHC class I, according to new research.

JAK inhibitors promising in colorectal cancer

By

JAK inhibitors have been found to halt tumor growth in colorectal cancer with a certain genetic mutation, according to a new study.

New analyses of epigenetics reveal tumor weaknesses

By

Scientists have known for decades that cancer can be caused by genetic mutations, but more recently they have discovered that chemical modifications of a gene can also contribute to cancer.

Bacterial biosurgery promising for reducing size of inoperable tumors

By

Deep within most tumors lie areas that remain untouched by chemotherapy and radiation. These areas lack the blood and oxygen needed for traditional therapies to work, but provide the perfect target for a new cancer treatment.
