ASTRO: SABR is effective for oligometastatic cancers
Stereotactic ablative radiotherapy (SABR) can greatly increase how long oligometastatic patients survive and doubles how long they live without cancer, according to new research presented at this week's American Society for Radiation Oncology (ASTRO) meeting.

DBT spots 34% more breast cancers than mammography
One-view digital breast tomosynthesis (DBT) detects 34% more breast cancers than traditional mammography -- with a majority of the detected tumors proving to be invasive cancers, according to a large clinical study in Sweden.

Cancer death disparities linked to poverty, lifestyle
Yale researchers have found that disparities in cancer death rates are linked to poverty and lifestyle factors across the U.S. The factors may provide public health experts with specific targets for potentially reducing such disparities, the researchers said.

Drop ultrasound contrast agent warning, society says
The International Contrast Ultrasound Society (ICUS) has filed a petition with the U.S. Food and Drug Administration urging the agency to remove boxed warnings from ultrasound contrast agents. ICUS believes the warnings are obsolete in light of clinical experience and recently released data on the safety of the agents.

Study claims breast screening does not reduce mortality
The findings of a new Danish-Norwegian study are reviving the claim that the recent drop in breast cancer mortality is not due to mammography screening but rather the result of improved treatment. The authors assert it's time to consider alternatives to mammography screening -- such as breast palpation by physicians.

Mammo uptake among veterans on par with nonveterans
Female veterans are as likely to undergo screening mammography as nonveteran women.
Patient examples of SPECT/CT and PET/CT RECIP 1.0. (A) SPECT and PET maximum-intensity projection (MIP) images in 74-year-old man with mCRPC. Serum PSA level at baseline was 449 ng/mL and slightly increased to 525 ng/mL after two cycles of Lu-177 PSMA. Eastern Cooperative Oncology Group (ECOG) score was 2 at baseline and increased to 3 after 2 cycles. The patient was classified by readers as RECIP-progressive disease on both SPECT and PET. Overall survival was 4.7 months. Two cycles of Lu-177 PSMA were administered. (B) SPECT and PET MIP images in 74-year-old man with mCRPC. Serum PSA level was 231 ng/mL at baseline and decreased to 12.5 ng/mL after 2 cycles of Lu-177 PSMA. ECOG score was less than 2 at baseline and after 2 cycles of Lu-177 PSMA. The patient was classified by readers as RECIP-partial response on both SPECT and PET. Overall survival was 14.3 months. Four cycles of Lu-177 PSMA were administered.
