New Test to Predict Breast Cancer

Philadelphia patients who are diagnosed and treated for a non-invasive type of breast cancer called ductal carcinoma (DCIS) are never sure if the cancer will return in a more invasive and dangerous form. Oncologists now have a new test that will help them advise patients with DCIS about their risks for developing breast cancer in the future.

Doctors and researchers studied the breast tissue of women diagnosed with DCIS and found those with certain characteristics were at a higher risk to suffer from another bout of breast cancer within eight years. This groundbreaking study will help doctors better weigh the treatment options for women with DCIS. Those with a low risk of developing breast cancer again will avoid invasive treatment and surgeries such as mastectomies and those with a high risk will be undergo treatments to try and prevent the cancer from returning.

This information will help doctors better diagnose and treat patients leading to happy and healthier lives to those diagnosed with the crippling disease of breast cancer.

New Device to Remove Blood Clots

Philadelphia area hospitals have a new device to remove blood clots from the body.

Blood clots are serious medical conditions that prevent blood flow in the body and can become fatal if not treated quickly. One of the more serious types of blood clot is a deep vein thrombosis or DVT and can form when people sit too long or are bed ridden. Symptoms of a DVT include muscle cramps and muscle stiffness and must be diagnosed by an x-ray or other digital imagining machine. A DVT usually forms in the leg and is classified as a medical emergency. If the clot breaks off and moves to the lung or the brain it can become fatal. Clots are usually treated through an IV injection of a blood thinner but not all patients respond to the medication and a new device is helping save patient's lives.

The Trellis Peripheral Infusion System is a catheter like device that is proving extremely effective in removing hard to treat blood clots. The thin catheter is inserted to the patient's body and balloons are inflated to isolate the clot. The device then vibrates and sprays blood thinner medication through tiny holes in the wire to break up the clot. Once the clot has been broken up the balloon deflates and the device is removed from the body. Some hospitals in the Philadelphia area are currently using the device and doctors are optimistic that this will be a more popular treatment in the future.

Stem Cells Repairing Hearts after Heart Attacks

Doctors at Drexel University College of Medicine in Philadelphia are using stem cells to help hearts repair themselves after a heart attack.

heart.jpgPatients are more likely to suffer from heart failure after a heart attack because scar tissue replaces part of the heart muscle causing it to grow in size and weaken. Doctors are now using adult stem cells to repair the heart after an attack. Patients must be infused with stem cells through I-V within seven days of an attack to have any likelihood of the heart being repaired.

The test seems to have lessened or prevented the common complications after a heart attack. Patients saw an improved heart function and fewer irregular heart rhythms when compared to patients who did not receive stem cells.

New Technique to Diagnosis Breast Cancer

For Philadelphia area women to best way to diagnosis an abnormal mammography is a needle biopsy but patients and physicians now have a new technique to aid in distinguishing between cancer and benign breast lesions.

The new technique, elastography, is added to a breast ultrasound study and measures the elasticity of the lesion. Malignant breast masses tend to be stiffer than cancerous masses. While ultrasound studies have been used for years to determine if the abnormalities on the mammogram were solid masses, it fails to distinguish if solid masses are cancerous.

A seven year study at a hospital in London compared elastography with needle biopsies and found that the elastography procedure correctly identified 98 percent of cancerous lesions. The study also discovered that elastography is more accurate in gauging the size of the lesions than a traditional ultrasound.

The new technique will not eliminate breast biopsies but an ultrasound performed with elastography will help patients and physicians make more informed decisions.

New Recommendation Regarding Mammograms Will be Dangerous to Women

Why is there now a new recommendation that mammograms not be routinely performed until a woman turns 50? Undoubtedly, the reason is cost. Isn't it interesting that this recommendation comes out on the eve of passage of a Health Care Reform Act?

Women in Pennsylvania and those within the United States were surprised when recently the US Preventive Services Task Force (USPSTF) issued new breast cancer screening guidelines.

These new breast cancer screening guidelines recommended against routine mammography screening in women before the age of 50 years and ending screening at age of 74.

Women were understandably upset and outraged by these new guidelines which set forth a mere 24 year window in which women are screened on a every two year basis, (making that a 12 year window) for the detection of breast cancer, which is a well known and leading cause of cancer and morality in women. Notably these new guidelines are in opposition with other existing breast cancer screening guidelines from such well known and relied upon sources as the American Cancer Society and the American College of Radiology.

These new guidelines update and replace the 2002 USPSTF guidelines and currently recommend:
• Against routine screening mammography in women aged 40-49 years of age
• Women ages 50 to 74 should undergo screening mammography every two (2) years
• Currently the task force finds no proven benefit/risk of screening mammography in women over 74 years of age.
• Currently the task force has determined there is insufficient evidence of additional benefits/risks of clinical breast examination (as performed by your doctor during office exams) in women 40 years of age or older, and so are not recommending continuing these exams.
• The USPSTF recommends against doctors teaching women breast self examinations.
• The task force has determined no additional benefits or risks of either digital mammography or MRI as opposed to x-ray mammography as a screening tool.

The USPSTF based its new published guidelines upon published reviews of the efficacy of breast screening based upon x-ray (film) mammography, clinical breast exams, breast self exams, digital mammography and MRI and upon 2 studies performed at the request of the task force. The task force reviewed the benefits and risks of screening, the effect it has upon health care costs and the timing (every 1 or 2 years), onset (age to initiate screening) and duration (ending at age 74) of breast cancer screening.

The reviewers cite that for women ages 39-49 mammography screening was associated with a 15% decrease in breast cancer mortality rates. They noted however, that there is lack of screening data for women over the age of 70. Overall radiation exposure from mammography is considered to be low and was not noted to alter screening practices by doctors. Over-diagnosis from mammography screening was determined to be 1 to10 %. Younger women were noted to have more false positive mammography results requiring additional imaging but fewer biopsies. Breast self exams were determined to result in more benign biopsy results and were associated with no decreases in mortality rates and so they are recommending doctors no longer teach this screening exam to women.

As an effort to recognize women who may fall outside these guidelines the USPSTF notes that women ages 40-49 who are at high-risk for breast cancer are encouraged to consult with their doctors concerning when to begin screening mammography.

The results of this recommendation if followed could be devastating to women. Over the years, we have represented many women who have suffered from breast cancer, some of whose families have lost them due to a delay in diagnosis of their breast cancer.

As we know the earlier you detect cancer the better the chance of a cure. Many women will lose their opportunity for early breast cancer detection if these guidelines/recommendations are followed.

Philadelphia Area Hospital one of Six in Country to Use New MRI Technique

Thomas Jefferson University Hospital located in Center City Philadelphia is one of only six hospitals in the country to currently implement the newest MRI an "extremity MRI." This new machine is primarily used on the limbs and does not require patients to enter a confined space. The extremity such as the arm or the leg is the only part of the body placed in the machine leaving patients free from the feeling of claustrophobia. With the patient free to interact and less nervous doctors are noticing that less movement is taking place allowing for the highest quality image.

This MRI is one of the most powerful diagnostic tests a doctor can use to examine patients, especially a soft tissue injury. Unfortunately most patients are hesitate to enter the MRI machine and when inside fidget around due to feelings of claustrophobia. Patients must lie completely still for the best quality MRI and for many patients that requires sedation. Open MRI machines where the patient is not completely enclosed are an alternate but due to a lower magnetic field images are not as powerful and diagnosis can become more problematic.

Regrettably many patients do not receive MRIs and suffer serious medical injuries as a result. Our Philadelphia Medical Malpractice firm has handled hundreds of cases where tests are not administered properly or in a timely matter and the end result is harm to patients. As technology advances it is our hope that this trend is reversed patients can receive accurate and timely diagnosis.
