5 billion people have no access to safe and affordable surgery, says study

A new study published in the Lancet medical journal suggests that two-third of the world population has no access to safe and affordable surgery.

It simply implies that millions of people are dying from conditions that can easily be treated like appendicitis and obstructed labor.

In 2010 itself, inaccessibility to safe and inexpensive surgeries resulted in deaths of almost 17 million people.

The Global Surgery 2030 Commission was written by 25 experts of surgery and anesthesia, with assistance from more than 110 countries, including India.

“More than 2 billion people are unable to receive surgical care based on operating theater density alone,” the study disclosed.

The findings of the study revealed, “At least 4·8 billion people worldwide do not have access to surgery. The proportion of the population without access varied widely in nations that are developed and those which are not. The proportion is greater than 95% in south Asia and central, eastern, and western sub-Saharan Africa, and less than 5% in Australasia, high-income North America, and western Europe lack access.”

The commission said that even those who are able to access surgery fall under great financial pressure due to high costs of the surgical procedures. Worldwide, a quarter of people who have a surgery incur costs that they cannot afford, which ultimately push them into poverty. This, in due course, prove that cost is a great barrier.

Andy Leather, Director of the King’s Centre for Global Health, King’s College London, and one of the commission’s lead authors said, “In the absence of surgical care, common, easily treatable illnesses become fatal.”

“There is a long way to go, but if the global health community wishes to address ongoing inequities and the growing burden of disease, improving access to surgical care cannot be ignored,” the report suggested.

Immunotherapy Drugs Show Significant Improvement Against Breast Cancer: Study

Side effects need a close look, both doctors said. Nearly all study participants had typical chemo side effects such as nausea or low blood cell counts.

For the first time, one of the new immunotherapy drugs has shown promise against breast cancer in a large study that combined it with chemotherapy to treat an aggressive form of the disease. But the benefit for most women was small, raising questions about whether the treatment is worth its high cost and side effects.

Results were discussed Saturday at a cancer conference in Munich and published by the New England Journal of Medicine.

Drugs called checkpoint inhibitors have transformed treatment of many types of cancer by removing a chemical brake that keeps the immune system from killing tumor cells. Their discovery recently earned scientists a Nobel Prize. Until now, though, they haven’t proved valuable against breast cancer.

In the study

The new study tested one from Roche called Tecentriq plus chemo versus chemo alone in 902 women with advanced triple-negative breast cancer. About 15 percent of cases are this type, their growth is not fueled by the hormones estrogen or progesterone, or the gene that Herceptin targets, making them hard to treat.

Women in the study who received Tecentriq plus chemo went two months longer on average without their cancer worsening compared with those on chemo alone, a modest benefit. The combo did not significantly improve survival in an early look before long-term follow-up is complete.

Failed protein test

Previous studies found that immunotherapies work best in patients with high levels of a protein that the drugs target, and the plan for the breast cancer study called for analyzing how women fared according to that factor if Tecentriq improved survival overall.

The drug failed that test, but researchers still looked at protein-level results and saw encouraging signs. Women with high levels who received the combo treatment lived roughly 25 months on average versus about 15 months for women given chemo alone.

That’s a big difference, but it will take more time to see if there’s a reliable way to predict benefit, said Dr. Jennifer Litton of the MD Anderson Cancer Center in Houston. She had no role in running the study but enrolled some patients in it and oversees 14 others testing immunotherapies.

“We’re really hopeful that we can identify a group of women who can get a much bigger and longer response,” she said.

Another breast cancer specialist with no role in the study, Dr. Michael Hassett at Dana-Farber Cancer Institute in Boston, said he felt “cautious excitement” that immunotherapy may prove helpful for certain breast cancer patients.

Side effects and cost

Side effects need a close look, both doctors said. Nearly all study participants had typical chemo side effects such as nausea or low blood cell counts, but serious ones were more common with the combo treatment and twice as many women on it stopped treatment for that reason.

Three of the six deaths from side effects in the combo group were blamed on the treatment itself; only one of three such deaths in the chemo group was.

Cost is another concern. Tecentriq is $12,500 a month. The chemo in this study was Celgene’s Abraxane, which costs about $3,000 per dose plus doctor fees for the IV treatments. Older chemo drugs cost less but require patients to use a steroid to prevent allergic reactions that might interfere with the immunotherapy. Abraxane was chosen because it avoids the need for a steroid, said one study leader, Dr. Sylvia Adams of NYU Langone Health.

The study was sponsored by Roche and many study leaders consult or work for the company or own stock in it. (VOA)
