“New 10-year results from a major clinical trial in breast cancer confirm that it does not compromise overall survival to leave behind minimal amounts of cancer that have spread to the underarm lymph nodes in certain patients, according to the investigators.
“The long-term data are from the American College of Surgeons Oncology Group Z0011 trial and were published online September 12 in JAMA.
“The study participants were women with clinical T1 or T2 invasive breast cancer, no palpable axillary nodes, and 1 or 2 sentinel lymph nodes containing metastases. In addition to lymph node management, all patients were treated with lumpectomy, tangential whole-breast irradiation, and adjuvant systemic therapy.”
“Ten-year overall survival for primary breast cancer patients treated with sentinel lymph node dissection (SLND) alone is similar to that seen in those treated with axillary lymph node dissection (ALND), according to a study published in the Sept. 12 issue of the Journal of the American Medical Association.
“Armando E. Giuliano, M.D., from the Cedars-Sinai Medical Center in Los Angeles, and colleagues compared the 10-year overall survival of patients with sentinel lymph node metastases treated with breast-conserving therapy and SLND alone without ALND (446 patients) versus women treated with ALND (445 patients). The women, with clinical T1 or T2 invasive breast cancer, all had planned lumpectomy, tangential whole-breast irradiation, and adjuvant systemic therapy.”
“The FDA has fully approved the Ablatherm high-intensity focused ultrasound device for the nonsurgical and noninvasive treatment of localized prostate cancer, according to a press release from the device’s manufacturer.
“Ablatherm high-intensity focused ultrasound (EDAP TMS), or Ablatherm HIFU, is recommended for men with localized prostate cancer (stages T1-T2) who are not candidates for surgery, who prefer an alternative option or who failed radiotherapy treatment.
“The device targets the tumor via a computer-controlled rectal probe. Ultrasound waves are intended to destroy the prostate tissue while sparing surrounding organs. Data have indicated the device is effective for prostatic tissue ablation with a low occurrence of side effects, according to the press release.”

The National Lung Screening Trial was conducted to determine whether three annual screenings (rounds T0, T1, and T2) with low-dose helical computed tomography (CT), as compared with chest radiography, could reduce mortality from lung cancer. We present detailed findings from the first two incidence screenings (rounds T1 and T2).
Low-dose CT was more sensitive in detecting early-stage lung cancers, but its measured positive predictive value was lower than that of radiography. As compared with radiography, the two annual incidence screenings with low-dose CT resulted in a decrease in the number of advanced-stage cancers diagnosed and an increase in the number of early-stage lung cancers diagnosed.
