Scientists are just beginning to understand the impact of diet on the gut microbiome and how this interaction affects human health, but baselines must first be established to yield answers. The first large-scale, longitudinal study to evaluate this interaction among Chinese adults indicates that long-term healthy eating yields microbiome diversity and an abundance of fiber-fermenting bacteria.

Breast-conserving surgery (BCS) plus radiotherapy is the standard-of-care for women diagnosed with early-stage breast cancer. For women over age 70, however, radiotherapy after BCS is controversial, and U.S. National Comprehensive Cancer Network clinical practice guidelines recommend that it may be omitted. 

The TAILORx study published last year offered good news for women with early-stage ER-positive breast cancer who scored at intermediate risk for recurrence according to a genetic assay test. The study indicated that chemotherapy after surgery provided little advantage in overall survival for these women, so they could forgo the treatment.

Six clinics across four U.S. states provided data for a newly validated clinical risk stratification model for lung cancer. The TREAT model (Thoracic Surgery, Research, Epidemiology, Diagnosis And Treatment) helps identify patients with suspicious lesions who are most likely to benefit from surgical biopsy. The aim is to mitigate unnecessary surgery for benign nodules and reduce delays for patients with early cancers.

Appendiceal cancer — cancer of the appendix — is a rare malignancy that is usually found during surgery for acute appendicitis. Although the rate of appendectomies has been stable over the last two decades, the incidence of malignant appendiceal cancer increased 232% in the United States.

Conventional colorectal adenomas are the precursor lesions for most colorectal cancers. In addition to these adenomas, other colorectal polyps are detected during colonoscopy. Sessile serrated polyps (SSPs) represent an alternative pathway to carcinogenesis that may account for 20-30% of colorectal cancer. Because a diagnostic consensus for SSPs was not reached until 2010, few epidemiologic studies have evaluated risk factors for SSPs.
