Step Counts for Cancer Prognosis: Could it Work for Mesothelioma?

step counts for cancer prognosis

Cancer researchers in New York are exploring the concept of using step counts for cancer prognosis. If further studies back it up, the technique might help predict outcomes for people with mesothelioma. The new study involved people with non-small cell lung cancer. The patients wore commercial fitness trackers so doctors could see how much they walked.  The researchers compared step levels with treatment outcomes. They concluded that there is value to using step counts for cancer prognosis. It may even be more effective than some more traditional methods for predicting survival. Cancer Prognosis and Chemoradiotherapy Mesothelioma survival usually depends on how well patients respond to standard treatments. Healthier, more active cancer patients tend to have better outcomes.  Chemotherapy and radiation … Continue reading Step Counts for Cancer Prognosis: Could it Work for Mesothelioma? »

Protein Marker Linked to Prognosis in Peritoneal Mesothelioma

A cellular marker that helps tell cancer cells to replicate may be used to predict treatment outcomes in people with malignant peritoneal mesothelioma. That conclusion comes from a group of researchers at Australia’s University of New South Wales. The researchers tested tissue samples from 42 mesothelioma patients for the presence of Ki67, a protein associated with cell proliferation. According to the authors, Ki67 has been widely used as a prognostic indicator in other types of cancer, but has not been tested in mesothelioma. The researchers divided the tissue samples into two groups based on their level of Ki67 expression. Those with a Ki67 expression of less than 25% were put in the low category and all samples above that were … Continue reading Protein Marker Linked to Prognosis in Peritoneal Mesothelioma »

Peritoneal Mesothelioma Survival May Depend on Cancer Location

physician and colleagues

Doctors in Greece believe they have found a more effective way to predict prognosis and perhaps extend the lives of people with peritoneal mesothelioma and other cancers affecting the peritoneum. It is based around a system than maps the location of cancer within the abdomen. Peritoneal mesothelioma is a rare form of one of the rarest cancers. Caused almost exclusively by asbestos exposure, peritoneal mesothelioma starts on the lining that surrounds the abdominal organs. A combination treatment of surgery followed by a wash of heated chemotherapy (HIPEC) through the abdomen is considered the gold standard therapy. Now, surgical oncologist John Spiliotis of the Metaxa Cancer Hospital in Piraeus, Greece along with colleagues in Greece and the US say the location … Continue reading Peritoneal Mesothelioma Survival May Depend on Cancer Location »

Mesothelioma Prognosis: Some Markers More Useful than Others

Deciding which treatments to try and determining whether they are working are two of the biggest challenges for patients with malignant pleural mesothelioma.  But a team of researchers in the UK is trying to make the process a little easier. They have identified three markers the say can help doctors predict prognosis in mesothelioma patients and monitor their response to treatment. The South West Area Mesothelioma and Pemetrexed trial, based in the Southwestern part of England, recruited 73 pleural mesothelioma patients between 2008 and 2011. Fifty-eight of the patients elected to undergo chemotherapy with pemetrexed (Alimta) for their mesothelioma and 15 opted only for best supportive care, without chemotherapy. Before treatment began, the researchers used PET-CT to test each patient’s baseline … Continue reading Mesothelioma Prognosis: Some Markers More Useful than Others »

Response to Talc Treatment May Predict Mesothelioma Prognosis

How well a mesothelioma patient’s lungs respond to a procedure designed to eliminate excess lung fluid may be a better predictor of survival than the stage or subtype of their cancer. A group of pathologists and thoracic surgeons in Italy came to that conclusion after evaluating the cases of 172 mesothelioma patients who underwent a procedure called talc pleurodesis or talc poudrage. Talc pleurodesis is designed to prevent a buildup of lung fluid that is common in mesothelioma patients and causes unpleasant symptoms like shortness of breath. After the lung fluid (also called pleural effusion) is drained, the space between the two pleural layers is filled with talc. The talc acts as a chemical irritant causing inflammation and fibrosis which … Continue reading Response to Talc Treatment May Predict Mesothelioma Prognosis »

Enzyme May Help Doctors Determine Mesothelioma Prognosis

Cancer researchers in New York say they have found a new way to help determine prognosis for people with malignant pleural mesothelioma. In a report in the Annals of Surgical Oncology, a team of doctors from Memorial Sloan Kettering Cancer Center say patients whose cancer cells tested positive for an enzyme called CD10 had more aggressive mesothelioma and shorter survival times. Right now, stage (a measure of how far cancer has spread in the body) and type are the primary prognostic factors for mesothelioma. People with more advanced cancer or non-epithelioid mesothelioma tend to have poorer outcomes than people with epithelioid or early-stage mesothelioma. By offering another reliable prognostic factor, the new study suggests that CD10 can help make the process more effective, which may improve … Continue reading Enzyme May Help Doctors Determine Mesothelioma Prognosis »

PET Supports Mesothelioma Diagnosis and Prognosis

Positron emission tomography (PET) is a nuclear medicine imaging technique that highlights metabolic activity in the body.  PET scanning detects gamma rays emitted by a tracer that is delivered into the body via a biologically active molecule, typically FDG, a form of glucose. FDG PET is one of the imaging tests sometimes used to help diagnose and monitor mesothelioma cancer on the pleural membrane around the lungs. Now, nuclear medicine specialists in Milan say FDG PET may be even more valuable than clinicians realize for predicting outcomes – especially in mesothelioma patients who are responsive to chemotherapy. The study involved 131 mesothelioma patients, most of whom were men, with a median age of 66. Study subjects were treated for mesothelioma … Continue reading PET Supports Mesothelioma Diagnosis and Prognosis »

Protein Biomarkers in Mesothelioma Diagnosis, Prognosis and Treatment

Three separate teams of international researchers have confirmed that proteins found in the blood can reveal some vital information for the diagnosis, treatment, and prognosis of pleural mesothelioma. These new studies on mesothelioma biomarkers indicate that all three of the studied proteins have value, but for different reasons. The most recent study comes from researchers in the Czech Republic who found that serum mesothelin, a protein overexpressed in several types of cancer, is valuable to measure the severity of mesothelioma in people who have already been diagnosed, but is unlikely to help doctors find the disease earlier. Doctors in the Department of Respiratory Medicine in Palacky University Olomouc followed 239 asbestos-exposed workers for nearly 20 years. They found that mesothelin … Continue reading Protein Biomarkers in Mesothelioma Diagnosis, Prognosis and Treatment »

Inflammatory Markers May Predict Mesothelioma Prognosis

Researchers say they have identified several signs of inflammation in patients with malignant mesothelioma that might be used to predict how patients will respond to treatment. Doctors from the Department of Chest Diseases at Dicle University collected data on 155 patients at the time of their mesothelioma diagnosis and compared it to their survival. The information collected included the extent of each patient’s exposure to asbestos, the histological subtype of their mesothelioma, and other laboratory measures. The mean survival time for all mesothelioma patients in the study was 13.9 months. When the researchers considered one potential prognostic factor at a time, they found that being 60 years old or over and having a neutrophil-to-lymphocyte ratio (NLR) of 3 or more … Continue reading Inflammatory Markers May Predict Mesothelioma Prognosis »

New Prognostic Factor in Peritoneal Mesothelioma

Malignant peritoneal mesothelioma is a rare form of mesothelioma that attacks the membrane that lines the abdomen and surrounds internal organs. The outlook for this rare malignancy, which affects fewer than 500 Americans annually, has been improved by the treatment combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The combination has produced 5-year overall survival rates ranging from 29% to 63%. But not all peritoneal mesothelioma patients are good candidates for CRS/HIPEC. The challenge, for clinicians, is identifying which patients are likely to benefit from the procedure (or even be cured) and which are not. In an effort to help answer that question, French researchers recently tested the prognostic value of the glucose transporter protein GLUT1 as well as … Continue reading New Prognostic Factor in Peritoneal Mesothelioma »
