More people are surviving a cancer diagnosis today than in the 1970s, according to a report released earlier this year by government agencies and cancer groups. That's the good news facing former Vice President Joe Biden, who's speaking with Mike Allen at an Axios event in Philadelphia today, as he continues his work to speed the progress of cancer research.

But the survival rates are still low for several kinds — including brain cancers like the type that killed his son, Beau Biden.

What's next: Immunotherapies are one promising area of cancer treatment, but there are questions about why checkpoint inhibitors (one class of immunotherapeutic drugs) work in some patients but not others. These treatments, and others known as CAR T-cell therapies that involve changing a patient's own immune cells so they will attack cancerous cells, can also cause serious side effects that researchers are racing to understand.

Dr. Elizabeth Jaffee of Johns Hopkins University, president-elect of the American Association for Cancer Research, says these are the most likely advances in immunotherapy to watch over the next few years:

  • Developing "accelerator" therapies to help the immune system activate more quickly.
  • Activating T-cells that have never been activated before by targeting monocytes, a type of white blood cell.
  • Inhibiting molecules formed when T-cells metabolize so the immune cells can better respond to cancerous ones.

Keep in mind: For breast, prostate and a handful of other cancers, increased screening and early detection may have improved survival rates while masking only minor gains in longevity. Prevention is how we've made the most headway in decreasing actual death rates from cancer — with fewer people smoking, for example — and where more progress can be made.

Scoop: Border officials project 13,000 child migrants in May

A Customs and Border Protection staffer told top administration officials Thursday the agency is projecting a peak of 13,000 unaccompanied children crossing the border in May, sources directly familiar with the discussion told Axios.

Why it matters: That projection would exceed the height of the 2019 crisis, which led to the infamous "kids-in-cages" disaster. It also underscores a rapidly escalating crisis for the Biden administration.

U.S. strikes Iran-backed militia facilities in Syria

The United States on Thursday carried out an airstrike against facilities in Syria linked to an Iran-backed militia group, the Pentagon announced.

The state of play: The strike, approved by President Biden, comes "in response to recent attacks against American and Coalition personnel in Iraq, and to ongoing threats to those personnel," Pentagon press secretary John Kirby said in a statement.

Senate parliamentarian rules $15 minimum wage cannot be included in relief package

The Senate parliamentarian ruled Thursday that the provision to increase the minimum wage to $15/hour cannot be included in the broader $1.9 trillion COVID relief package.

Why it matters: It's now very likely that any increase in the minimum wage will need bipartisan support, as the provision cannot be passed with the simple Senate majority that Democrats are aiming to use for President Biden's rescue bill.
