that something was wrong with her body: despite the good food she had little appetite. Until then, the 55-year-old still had something in his line

Recognizing Cancer Cells

Immunotherapy, on the other hand, is not targeted directly at cancer. On the contrary, she tries this

Inflammation of the lungs, intestines, liver or thyroid gland can lead to it.
Nevertheless, immunotherapy is promising: in 2013, the journal "Science" called it "breakthrough of the year". Alfred Zippelius also speaks of a long-awaited breakthrough in oncology. Although he admits, "Unfortunately, immunotherapy can only help a minority of patients." For lung cancer, it is 20 to 25 percent, for other types of cancer between 30 and
40 percent who have immunotherapy. And there are also cancers like

That the body can help itself in the fight against cancer is not a new knowledge." Already in the 1890s, the New York surgeon William observed

German doctor and researcher Paul Ehrlich has expressed the thesis that
the human immune system can detect and destroy cancer cells.
However, it took more than 100 years for the first immunotherapeutic drug to enter the market. For decades, researchers in Germany and abroad have been working on various approaches, without the hope of breakthrough has come. "For a long time, we, the immunologists, were outsiders in oncology," explains Daniel Speiser.

First Successes
He was not discouraged by critical voices and skeptics. Already as a young boy
Doctor at the University Hospital of Geneva, he had seen with his own eyes, what
The role of the immune system plays in patients with leukemia: after a bone marrow transplant, he repeatedly saw patients who would have died shortly after treatment because they were so full of leukemia cells. "But the opposite happened: in a few days, the donor's immune cells killed the leukemic cells and the patients became healthy again." Since then, he is interested in the immune system forces in the fight against cancer, even without transplantation [19659002]

The first successes appeared ten or so years ago in the fight against blacks

Radiotherapy has little or no effect, that it is always open here
Reinhard Dummer, head of the Skin Tumor Center at the University Hospital Zurich, had to experiment with new approaches. "I have treated several thousand patients in unsuccessful clinical trials." This has changed with the introduction of new immune antibodies. Shortly after the beginning of the millennium, he began to associate the first patients with clinical trials
treat. "The efficiency was not immediate, but after several years
we found that about 20 percent of the patients were still alive, in the control group
he was only 2 to 5 percent.
In 2011, the first immunotherapeutic agent was used in Switzerland for the treatment

Lung cancer is treated today in Swiss hospitals by immunotherapy. Depending on the type of cancer, it is a first-line treatment or used concomitantly or after chemotherapy.
"I would have done almost anything to pay for this treatment." Karin Wenger, cancer patient
when Karin Wenger was confronted with the question of how to proceed
should, was in Switzerland, a single active ingredient on the market. And this one was
first approved for the treatment of black skin cancer. For patients with cancer
At the time, several clinical trials were underway to which Wenger could have participated. "It was out of the question for me," she says. "I did not want to risk being assigned to the control group and just getting standard chemotherapy." The only option left was the approved drug.
to pay out of pocket
With about 10,000 francs per infusion administered every two weeks,
a very expensive option. "Like Mr. Zippelius and the lung specialist at the time
I asked him what they would do for me. Mr. Zippelius said that he would sell the Mercedes that he did not have. I replied that if necessary I sell the BMW that I have. I would probably have almost everything
made to pay for this treatment. This little chance for a piece of more
of life.
The society must decide
Today the health insurance funds support the treatment of an immunotherapy
even with lung cancer. But the high cost of new cancer drugs
remains an unresolved problem. "The treatment of a single patient can
costs 100,000 francs a year, "says oncologist Alfred Zippelius.
"When multiple drugs are combined, even multiple times.
we will massively burden our health insurance. »The immunologist of Lausanne
Daniel Speiser says, "We need to use these expensive therapies because we use them

The pharmaceutical industry and health care must collaborate more closely. Daniel Speiser, Physician and Immunologist
Among other things, new pricing models are being discussed, so that expensive drugs are only paid should be, if they actually work and
prolong the life of a patient. "The pharmaceutical and health care industry urgently need to work more closely together, so that further development
is coordinated and costs can be better understood, "says Daniel

Meanwhile, science is intensively investigating what we call biomarkers, that is,
Genes, molecules or cells that can be used to predict
how a disease develops or if a medicine works. "Currently
we still have no way to clearly predict who will receive immunotherapy
and who will not benefit, "said Ulf Petrausch, oncologist and immunologist
at OnkoZentrum Zurich. "In 60% of patients, expensive drugs are used for free."

Karin Wenger has finally had its immunotherapy but not alone
Pay the bag. A pharmaceutical company has just had an early access program
for a drug yet to be approved, Alfred Zippelius has registered Wenger and other of his lung cancer patients. And already a few weeks
later came the commitment. End of May 2015 sank at Basel University Hospital
the first dose of the drug in Wenger's veins. The side effects were similar to those of chemotherapy; they were less tight, but they did not have it
after months new: debilitating fatigue, gastrointestinal problems, joint pain. His thyroid was inflamed and stopped working. but
cancer also responded: metastases had already decreased significantly in July.
After a few months they had completely disappeared and until today they did not come back. And this, although Wenger received the last infusion in February 2017. His lungs are severely healed by radiotherapy
and so not easy to judge, but to date cancer also seems
stay quiet there. Wenger's immune system now holds him in check.

Living with Side Effects learned
"Fatigue is still getting me ready today," says Wenger. She needs ten hours of sleep each night, has to go to sleep again in the afternoon, she can not concentrate long, needs more time than before. Meanwhile, the stents in his airways are ingrown, with secretions and bacteria building up behind them, so that Wenger has a chronic cough and inflammation.
"But I live," she says. "I can adapt to side effects." And she adds: "I was only one of the first lung cancer patients in Switzerland, one of
