Surgical intervention for mesothelioma has become widely accepted, but controversy persists: Should surgery be the standard of care or should it be offered only to select patients? According to scientific literature, surgery decreases morbidity and mortality while also improving outcomes compared with adjunctive therapy alone.

The first major study to address the cardiovascular adverse effects of endocrine therapy for prostate cancer could change attitudes toward treatment options because testosterone deprivation may have more impact on the patient’s life than it does on the androgen receptor.

MINNEAPOLIS-When it comes to taking stock of an oncology practice’s productivity, less is more. It benefits a practice to develop a few meaningful benchmarks rather than multiple overlapping, overwhelming, and meaningless measurements.

Researchers are exploring ways to manipulate rituximab (Rituxan) when added to the current standard therapy for diffuse large B-cell lymphoma, specifically shortening the number of treatment days. Preliminary results of a phase III trial showed that rituximab plus CHOP over a 14-day cycle achieved similar response rates and comparable toxicity compared to CHOP on a 21-day cycle in newly diagnosed patients.

Ultrasound is an effective way to monitor lymph node recurrence after breast cancer surgery, South Korean researchers reported. Regional lymph node recurrence affects just 2% to 16% of patients with any stage of breast cancer, but is difficult to manage and associated with poor prognosis.

A review article asserting breast MRI does not improve surgical planning, reduce follow-up surgeries, or reduce the risk of local recurrences drew the ire of the breast imaging community.

The incidence of later-stage breast cancer has not kept pace with a substantial increase in diagnosed breast cancers, an increase achieved largely by the use of better imaging equipment and a nearly 70% screening rate among women 40 years and older. This fact, underscored in a special communication in the Journal of the American Medical Association, pokes holes in the widely held public belief that early diagnosis will prevent the majority of breast cancer deaths.

Owen Witte, MD, has been a California resident for nearly 35 years, but there’s nothing laid-back about him. The director of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research retains the rapid fire speech of a native New Yorker. Although it was getting toward late afternoon when Dr. Witte met with Oncology News International, he ushered a steady stream of visitors into and out of his office at the University of California, Los Angeles. When he spoke about his work, it was with the same energy that no doubt drew him to science in the first place.

BERLIN-A pair of colon cancer trials using panitumumab (Vectibix) not only proved the efficacy of the drug in patients with nonmutated KRAS but also highlighted the importance of ascertaining KRAS status. Trial 181 evaluated panitumumab in combination with FOLFIRI as a second-line treatment for metastatic colorectal cancer, while trial 203 paired the anti-EGFR agent with FOLFOX4 as first-line treatment.

CHICAGO-Radiation of the lymph nodes of high-risk melanoma patients appears to significantly reduce the risk that cancer will recur in those nodes, researchers said at ASTRO 2009. The study was deemed practice-changing, representing the first advance in the management of melanoma in nearly two decades.

Researchers in the U.S. and Italy report that women with HER2-positive breast cancers that are 1 cm or less in diameter and are node-negative have a risk of recurrence that is two to five times greater than that of women with HER2-negative breast cancers (J Clin Oncol online, November 2, 2009).

Despite the hubbub, breast imaging researchers saw nothing new in the findings of Dr. Esserman’s group. Daniel Kopans, MD, a professor of radiology at Boston’s Massachusetts General Hospital, called her observation about mammography catching nonlethal cancers but missing aggressive ones “a fundamental concept that is older than I am. Mammography saves lives by finding moderate- and slow-growing cancer that will kill in five or more years without diagnosis and treatment,” according to Dr. Kopans.

Cannabinoids, which are a byproduct of marijuana smoke, have been recognized to have potential antitumor properties, but evidence of a relationship between marijuana use and the induction of head and neck squamous cell carcinoma has been inconsistent.

Head and neck patients who undergo surgery first are more likely to complete radiation therapy, according to Seattle-based researchers. Megan Dann Fesinmeyer, PhD, MPH, and colleagues noted that radiation dose and treatment duration correlated with tumor control and survival, but that breaks in radiotherapy have been associated with inferior tumor control.

A modified radical hysterectomy (class II) did not improve locoregional control and survival compared with simple extrafascial abdominal hysterectomy (class I). Investigators from University of Milano-Bicocca in Monza, Italy, randomized 520 patients with stage I endometrial cancer to class I or class II surgery. They found that the median length of parametria and vagina removed were 15 mm and 5 mm respectively for class I hysterectomy vs 20 mm and 15 mm for class II hysterectomy (P > .001). Operating time and blood loss were statistically significantly higher for class II hysterectomy. Five-year disease-free survival and overall survival was 87.7% and 88.9% respectively in the class I arm, and 89.7% and 92.2% in the class II arm (Ann Surg Oncol online, October 16, 2009).

Annick Van den Abbeele, MD, couldn’t believe her eyes. Dr. Van den Abbeele, the chief of radiology at Boston’s Dana-Farber Cancer Institute, had seen the patient just a month earlier. At that time, the 35-year-old woman had a gastrointestinal stromal tumor in her abdomen that was so large, she looked six months’ pregnant. But at the patient’s follow up FDG-PET study, the tumor was completely gone.
