Under- and over-imaging suspected in prostate cancer care

Under- and over-imaging suspected in prostate cancer care

For men with nonmetastatic castration resistant prostate cancer with a negative bone scan after diagnosis, factors associated with a second bone scan include higher PSA, shorter PSA doubling time, and faster PSA velocity; but under- and over-imaging may also be a factor.

MRI detection of sugar molecules on cells may enable distinction of cancer vs noncancerous cells

By

Study data suggests that magnetic resonance imaging (MRI) could one day make biopsies more effective, or even replace them altogether, via noninvasive detection of telltale sugar molecules shed by the outer membranes of cancerous cells.

Photodynamic therapy for pancreatic cancer made simpler and cheaper

By

Present barriers for the usual dosimetry accompanying photodynamic therapy (PDT) for late-stage pancreatic cancer can be overcome via clinical technologies.

Early recall rates decline after second round of lung cancer screening

Early recall rates decline after second round of lung cancer screening

By

When low-dose computed tomography is used for second and subsequent lung cancer screening, the rate of repeating early repeat scans for suspicious findings decreased by more than 80%.

Treatment guidelines for pediatric Hodgkin lymphoma issued by the International Lymphoma Radiation Oncology Group (ILROG)

By

The International Lymphoma Radiation Oncology Group (ILROG) has issued a guideline outlining use of 3-D computed tomography (CT)-based radiation therapy planning.

Inappropriate breast and prostate imaging of Medicare beneficiaries examined

By

An association of high rates of inappropriate imaging for prostate cancer and breast cancer found in a study of Medicare beneficiaries suggests that regional culture could contribute to inappropriate imaging.

Long-term follow-up of benign thyroid nodules shows favorable prognosis

By

Detection of asymptomatic thyroid nodules has increased, and the majority of benign thyroid nodules examined did not lead to a diagnosis of thyroid cancer, according to a recent study.

Magnetic resonance spectroscopy (MRS) shows precancerous breast changes in women with BRCA gene mutation

By

MRS that incorporates monitoring of biochemical changes in tissue could improve the management of women at risk of breast cancer, according to a new study.

Additional PET/CT scans have value in follow-up of lung cancer patients

By

Research indicates a high value of scans that could lead to future change of reimbursement policies for follow-up PET/CT studies in lung cancer.

Ultrasound helps determine which breast cancer patients need lymph nodes removed

By

Not all women with lymph node-positive breast cancer treated with chemotherapy before surgery need to have all underarm nodes removed, new research indicates.

Targeted MRI-ultrasound is better than standard biopsy at detecting high-risk prostate cancer

By

Targeted magnetic resonance (MR)/ultrasound fusion biopsy outperformed standard biopsy technique for increased detection of high-risk prostate cancer, according to a recent study.

Less cancer-related imaging in Department of Veterans Affairs (VA) health system

Less cancer-related imaging in Department of Veterans Affairs (VA) health system

Lower use of imaging seen in the VA than in fee-for-service Medicare; not associated with less geographic variation.

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.

Breast cancer tumor response to neoadjuvant chemotherapy (NAC) measured

By

Diffuse optical spectroscopic tomographic imaging (DOST) may be useful in predicting which patients will best respond to chemotherapy used to reduce breast cancer tumors before surgery, according to a new study.

Breast cancer is more accurately diagnosed after PET/CT imaging in younger patients

By

A change in diagnosis resulted from PET/CT imaging of patients who were younger than 40 years with an initial diagnosis of stage I-III breast cancer, according to a retrospective analysis.

Accuracy of lung cancer screens in some geographic regions questioned

By

Positron emission tomography and fludeoxyglucose F18 is less accurate in diagnosing lung cancer from benign disease in areas where histoplasmosis or tuberculosis infections are common.

Lung infections may lessen chance of detecting lung cancer

Lung infections may lessen chance of detecting lung cancer

Certain conditions make it harder to reliably detect tumors, and regions with locally-endemic infectious lung diseases pose an added hurdle for lung cancer detection.

Monitoring the response of bone metastases to treatment with MRI and PET

By

The European Journal of Cancer has released a position statement on recent developments in MRI and PET and how these techniques can be used to detect bone metastases.

Rethinking Breast Cancer Screening: Ultra FAST Breast MRI [EDITORIALS]

Rethinking Breast Cancer Screening: Ultra FAST Breast MRI [EDITORIALS]

Breast cancer screening is once again controversial. In this editorial, the author discusses new research demonstrating the effectiveness of an MRI imaging technique called first postcontrast subtracted T1-weighted image (FAST).

Research team makes cancer glow to improve surgical outcomes

Research team makes cancer glow to improve surgical outcomes

Surgical resection is the most effective method for a cancer cure; however, the procedure may not remove the entire tumor, leading to local recurrence. Researchers at the University of Pennsylvania have established a new strategy in which near-infrared (NIR) imaging is used to help visualize the entire tumor.

Noninvasive advanced image analysis may improve care for lung cancer patients

By

Lung cancer patients could receive more precise treatment, and their progress could be better tracked by using a new high-tech method of non-invasive medical imaging analysis, according to a new study.

Combination imaging helps breast tumor differentiation

Combination imaging helps breast tumor differentiation

The use of new technique, which includes four approaches, could reduce unnecessary breast biopsies.

Combination imaging can distinguish malignant and benign breast tumors

Combination imaging can distinguish malignant and benign breast tumors

By

Imaging breast tumors using four approaches together can better distinguish between malignant breast tumors and those that are benign, compared with imaging using fewer approaches.

Molecular imaging visualizes novel way to knock down breast cancer

By

A recent innovation in breast cancer biomarkers seeks to visualize the HER3 receptor, which could mean more comprehensive breast cancer imaging and potential treatments.
