This video examines current options for the treatment of midgut neuroendocrine tumors and highlights results of the NETTER-1 trial.

This video examines the results of a prospective study that looked at associations between survival outcomes and fish and omega-3 fatty acid intake among colon cancer patients.

This video examines a population-based study that examined colorectal cancer mortality and gastrointestinal bleeding in patients with long-term use of low-dose aspirin.

This video examines a pair of studies that looked at molecular variances and clinical differences between left-sided colon and rectal cancers.

The immune checkpoint inhibitor nivolumab showed durable responses and disease control in a group of heavily pretreated patients with DNA mismatch repair deficient/microsatellite instability high (MSI-H) metastatic colorectal cancer.

Using immunohistochemistry to measure the expression of certain target enzymes-cox-2 and 15-prostaglandin dehydrogenase (15-PGDH)-in premalignant colorectal adenomas, researchers were able to get significant predictive and prognostic information in patients treated with the cox-2 inhibitor celecoxib for prevention of colorectal adenomas.

The addition of the BRAF inhibitor vemurafenib to irinotecan and cetuximab prolonged progression-free survival and resulted in a higher disease control rate than treatment with irinotecan and cetuximab alone in patients with BRAF-mutant metastatic colorectal cancer.

Adjuvant chemotherapy for biliary tract cancer using GEMOX (gemcitabine/oxaliplatin) was feasible, but did not result in an improved recurrence-free survival or quality of life compared with surveillance in the phase III PRODIGE 12-ACCORD 18 trial.

This video covers results of the SWOG 1406 study, which tested the BRAF inhibitor vemurafenib in combination with irinotecan and cetuximab for patients with metastatic, BRAF-mutant colorectal cancer.

Use of stereotactic body radiation therapy (SBRT) was equally effective as transarterial chemoembolization (TACE) as a method of bridge to transplant among patients with hepatocellular carcinoma.

This video examines results of the CHARTA trial, which tested first-line FOLFOX plus bevacizumab with or without irinotecan in patients with advanced colorectal cancer.

This video examines an exploratory analysis of the RESORCE trial, which tested regorafenib vs placebo in hepatocellular carcinoma patients following radiographic progression on sorafenib.

Ahead of the 2017 ASCO Gastrointestinal Cancer Symposium in San Francisco, we spoke with Dr. Geoffrey Ku on the advances in systemic therapy for esophageal and gastric cancer.

Patients with metastatic colorectal cancer who engaged in more hours of physical activity at the time of their diagnosis had improvements in both progression-free and overall survival compared with patients who had less physical activity.

Using a watch-and-wait strategy among a group of highly selected patients with rectal cancer who have undergone neoadjuvant chemoradiation did not appear to compromise outcomes.

Using PET scans during induction chemotherapy for esophageal cancer, researchers were able to assess patient response to treatment and adjust their therapy, leading to an improved rate of pathologic complete response prior to surgery.

This slide show includes some of the top highlights from the 2016 ASCO Genitourinary Cancers Symposium, including studies on hypofractionation in low-risk prostate cancer, cabozantinib in advanced RCC, and more.

In this interview we discuss predictive biomarkers and response to immune checkpoint inhibitors for urothelial tumors, which include tumors of the bladder, ureters, and the renal pelvis.

A study found that about half of advanced germ cell tumor patients with platinum-resistant or -refractory disease harbor potentially actionable mutations.

An Egyptian study found that bladder cancer patients who underwent radical cystectomy had better local recurrence-free survival with adjuvant radiotherapy and chemotherapy combined, compared with chemotherapy alone.

Results from the large STAMPEDE trial suggest that the combination of zoledronic acid and celecoxib along with standard of care could improve failure-free survival in prostate cancer patients starting hormone therapy whose disease has metastasized.

The combination of the novel histone deacetylase inhibitor entinostat and high-dose interleukin-2 yielded a promising response rate in patients with metastatic renal cell carcinoma.

A three-arm trial found that one hypofractionation radiotherapy regimen was non-inferior to conventional RT for intermediate-risk prostate cancer patients.

The anti-PD-L1 antibody atezolizumab showed significantly improved objective response rates compared to historic controls in a phase II study of patients with locally advanced or metastatic urothelial carcinoma previously treated with platinum-based therapy.

A hypofractionated radiotherapy regimen was found to be noninferior to conventional fractionation for low-risk prostate cancer patients in a new randomized phase III trial.

Progression-free survival in advanced renal cell carcinoma patients treated with cabozantinib was nearly doubled compared with those treated with everolimus, according to data from the METEOR trial.

Men who take aspirin regularly may have a lower risk of dying from prostate cancer, according to results of a large observational study.

Prostate cancer patients who have a more heterogeneous set of detectable circulating tumor cells are more likely to develop resistance to anti-androgen therapy, according to the results of a new study.

At this year’s ASCO GU Cancers Symposium, several high-impact and potentially practice-changing abstracts were presented during the prostate cancer session.

Phase II study results found that half of patients with relapsed or refractory urothelial carcinoma responded to treatment with pazopanib and paclitaxel.
