Many women with early breast cancer may not need chemo, study finds

The study is thought to be the largest breast cancer treatment trial ever

"It's a great news story".

It wasn't looking good for Judy Perkins. By continuing the personalized assessment of an individual's cancer recurrence risk, oncologists can more effectively determine specifically-tailored treatments based on that patient's genomic results.

Avoiding chemotherapy may come as a relief to many women who are diagnosed with breast cancer, as the treatment comes with a number of side effects, including nausea, hair loss and anemia.

Perkins really is lucky.

Dr Steven Rosenberg, chief of surgery at the National Cancer Institute, which led the trial, told the broadcaster that the therapy remained "highly experimental", but had the potential to transform cancer treatment.

British experts said the study was "exciting" even though it involved just one patient.

What his findings mean, he says, is that oncologists have to recognize that cancer is unique to every patient, and that treatments must reflect that. Patients using both types of treatment had an overall survival rate of 93.8 percent.

Perkins' immune system was already trying to fight off the tumors that had spread across her torso.

The challenge so far in cancer immunotherapy is it tends to work spectacularly for some patients, but the majority do not benefit. Researchers first plucked a rare type of T-cells, custom-made by the immune system from inside the tumors.

The scientists screen the patient's white blood cells and extract those capable of attacking the cancer. "It opens the door to the treatment of nearly any cancer".

The immune cells, known as tumour-infiltrating lymphocytes (TILs), were removed from the patient, multiplied under laboratory conditions and injected back into the bloodstream in large numbers. She had a lumpectomy, followed by a mastectomy, and had a recurrence score of 12 or 13, which put her in the middle range. So we have two yes-no answers for each gene.

Targeted cancer drugs are formulated to match specific mutations seen in specific cancers.

The patient with advanced colon cancer whom Rosenberg's team treated in 2015 is Celine Ryan of MI. It could be that they're too weak, or too few.

"It feels miraculous and I am beyond amazed", the 52-year-old said.

Chemotherapy may be avoided in about 70% of early-stage breast cancer patients, thus limiting chemotherapy to the 30% for whom it can be predicted to be beneficial, a study released on Sunday (3 June) shows.

Dr. Jennifer Litton at MD Anderson Cancer Center in Houston, agreed, but said, "Risk to one person is not the same thing as risk to another".

Professor Boyle said several immunotherapy trials for triple negative breast cancer are about to start in Australia. And even though it is very expensive and very complicated, CAR-T can be successful, he noted.

"This is a hard call when you are actually the one with the breast cancer", an early-stage breast cancer survivor from Middleton, Massachusetts, told LifeZette.

Thousands of breast cancer patients may be safely spared the "agony of chemotherapy" thanks to new genetic testing.

"We are now at the cusp of a major revolution", Radvanyi wrote in a commentary. Tests after 42 weeks showed Perkins was completely cancer free. "Now, I have gone back to normal everyday life". The Foster City, California-based company is building out a pipeline of cancer drugs after years of success with treating viral infections such as hepatitis and HIV.

"We have been using Oncotype DX for some years now among women in tumours that are less than 4 cm with no axillary lymph nodes, estrogen progesterone receptor positive and HER 2 new negative".

She just completed the Florida kayak trip and looks forward to more.
