Colorectal tumors that lacked the ability to repair DNA were found to be highly responsive to checkpoint blockade with the anti–PD-1 drug pembrolizumab.

Ahead of the 2015 ASCO Annual Meeting, we are discussing over-the-counter therapies for patients with metastatic colorectal cancer with Andrew T. Chan, MD, MPH.

The CONCUR trial found that regorafenib improved overall survival in a large group of Asian patients with treatment-refractory metastatic colorectal cancer.

A 59-year-old man with metastatic gastric cancer presented to the oncology clinic with a 1-week history of positional headache, nausea, and vomiting. He stated that the headache was located in the frontal region, was 8 on a scale of 10 in intensity.

TAS-102, an oral combination of trifluridine and tipiracil hydrochloride, improved median overall survival in patients with refractory colorectal cancer.

Metformin, a common drug for type II diabetes, did not improve the survival of patients with pancreatic ductal adenocarcinoma.

The FDA has approved ramucirumab, a human VEGFR2 antagonist in combination with FOLFIRI for second-line treatment of patients with metastatic colorectal cancer.

Metastatic colorectal cancer patients had about a 1.5-month increase in overall survival when treated with second-line ramucirumab plus FOLFIRI vs FOLFIRI alone.

An MRI screening program for individuals at high risk for pancreatic cancer may be effective, according to the results of a short-term study.

Patients who had either laparoscopic surgery or open surgery for localized rectal cancer had similar overall survival and disease-free survival rates.

The risk of bone metastases from GISTs, though rare, should be considered during long-term follow-up of patients, especially in those with liver metastases.

Current use of statins was associated with about a 50% decreased risk for liver cancer, according to results of a study looking at data from the United Kingdom.

If US colorectal cancer screening is increased to 80% by 2018, a new study predicts a decrease in both cancer incidence and mortality within 20 years.

A retrospective analysis found that high expression levels of two angiogenic factors were associated with poor prognosis in esophageal cancer.

Although genomic testing can improve the cost-effectiveness of a treatment, assessing the cost-effectiveness of genomic testing outside the context of its impact on treatment is not practical.

The identification and characterization of gene signatures, driver events, and pharmacogenomics in molecularly homogeneous subsets of patients is likely to advance effective drug development strategies in colorectal cancer.

Numerous genomic tests are available for use in colorectal cancer, with a widely variable evidence base for their effectiveness and cost-effectiveness. In this review, we highlight many of these tests, with a focus on their proposed role, the evidence base to support that role, and the associated costs and risks.

Looking at a large group of early-onset colorectal cancer patients, only 1.3% had TP53 mutations, none of whom met criteria for Li-Fraumeni syndrome.

In a large study, it was found that those who ate a vegetarian diet had a lower risk of colorectal cancer compared with their non-vegetarian counterparts.

Bevacizumab as first-line therapy for metastatic CRC equated to an incremental cost-effectiveness ratio of more than half a million dollars per QALY.

Patients with lung and colorectal cancer who understood that chemotherapy would not cure them were no less likely to receive chemotherapy at the end of life.

A new study suggests that cancer patients do not often request unnecessary and sometimes costly tests or treatments.

According to a large study, men with a CDH1 gene mutation have a 70% incidence of gastric cancer by the age of 80 years and women have a 56% incidence.

The US Food and Drug Administration has granted orphan drug designation to tarextumab for the treatment of pancreatic cancer and small-cell lung cancer.

Adding cetuximab to FOLFIRI resulted in improvements in survival and objective response in patients with KRAS codon exon 2 wild-type metastatic colorectal cancer.
