1. Surviving Mesothelioma
According to the American Cancer Society, up to about 10 percent of
people with malignant mesothelioma live at least five years after the
disease is diagnosed. While that leaves miles of room for
improvement, the statistic nevertheless means that a substantial
fraction of patients are surviving mesothelioma—a fraction that is
likely to grow with each passing year.
That’s because survival figures for mesothelioma, as well as for
other cancers, are based on outcomes of patients in the past, who
received whatever treatment was available back when they first learned of their
mesothelioma diagnosis. Even minor innovations in surgery or postoperative care, as well as
more substantial advances in chemotherapy or other medicines, can immediately benefit
individual patients. That impact, though, can take years to begin to show up in average
survival statistics. For instance, the mesothelioma treatment pemetrexed disodium (Alimta),
which is given with another chemotherapy drug to patients who aren’t candidates for
surgery, received U.S. government approval just seven years go, meaning that any ability
to nudge up survival statistics is only beginning to appear.
In the broader war on cancer, there is even more reason for hope. In the war on cancer,
many powerful weapons are in development, and in some cases, already on the battlefield.
Consider a rare cancer of the white blood cells known as chronic myeloid leukemia (CML).
Until the introduction of a new drug, called imatinib (Gleevec), in the United States in 2001,
less than one-third of patients with CML survived for five years. The new medicine, clinical
trials show, boosted that survival rate to around 90 percent or more—and is now the
standard of care for that disease.
Also, knowledge from the development of one such weapon—even if it isn’t designed to
specifically attack malignant mesothelioma—can yield insights that will help in the battle
against asbestos-caused disease. Every day scientists are learning more about how to
attack specific tumors, how a tumor’s environment in the body can help or hinder its
growth, and what special tricks tumors use to thrive and spread. A multitude of research
studies are under way to translate that knowledge into action.
Meanwhile, the medical literature on mesothelioma reflects how individual miracles happen.
A report in January 2011 in the Journal of Medical Case Reports described a woman in her
40s who is alive and well seven years after diagnosis with peritoneal mesothelioma, a
cancer of the lining of the abdomen. Her physicians attribute her good fortune to the
contained nature of the disease, her successful surgery and chemotherapy, and specific
characteristics of her tumor tissue. Another case report, appearing just a month earlier in
the journal Diagnostic Pathology, describes a patient who developed pleural mesothelioma,
a cancer of the lining of the lungs, after asbestos exposure and was healthy 14 years after
symptoms appeared, and a dozen years after surgery and chemotherapy. And a report from
2007, appearing in the journal The Annals of Thoracic Surgery, recounts a surgical patient
whose pleural mesothelioma spontaneously regressed. The patient experienced just a single
recurrence six years into a 12-year follow-up period, and that tumor in the chest was
successfully removed.
In short, as oncologists and other experts will readily acknowledge, statistics reflect the
history of a group—not the future of an individual.

2. Taking a Shot at Mesothelioma
Researchers at Memorial Sloan-Kettering Cancer Center in New York City are recruiting
patients for a clinical trial to test a ―vaccine‖ under development for the mesothelioma
treatment.
Unlike many well known vaccines—such as a shot to protect against onset of illnesses such
as the flu or the mumps—this vaccine is intended to be given to people who already have
malignant pleural mesothelioma, a cancer of the lining of the lung. Very preliminary tests
have suggested that the experimental vaccine can mobilize a patient’s own immune system
to attack mesothelioma cells.
Specifically, the vaccine appears to target WT1, a type of protein that binds to a specific
part of the DNA code, affecting the transfer of genetic information and impacting how cells
function. WT1 is especially abundant in cells from many people’s mesothelioma tumors.
The preliminary tests, whose results were published in fall 2010 the journal Cancer
Immunology, Immunotherapy, found that the vaccine worked to mobilize two different
types of immune cells known as T cells, and those T cells were able to kill the cancer cells
with abundant WT1. Also, the vaccine was well tolerated, causing minimal problems with
side effects among test patients, the researchers noted.
Participants in the preliminary trial, which included both malignant mesothelioma patients
and those with non–small-cell lung cancer, received six doses of the vaccine, injected under
the skin, along with an immune-boosting substance. Injections were given at the start of
the study, and four, six, eight, 10 and 12 weeks later. People whose tumors responded
received additional injections once a month.
While only a handful of patients received the vaccine in this early trial, a majority of them
showed an immune response to the treatment, setting the stage for the current, Phase II
randomized clinical trial. The new trial is for adult patients who have had their pleural
mesothelioma tumors surgically resected and have received chemotherapy or radiation. Half
the participants will receive a series of shots over 10 weeks containing the WT1-targeted
vaccine, along with some general immune-boosting medicines, while the other half will
receive those general immune boosters alone. Neither the patients nor the researchers will
know who received which treatment.
The research team, which hopes to enroll 78 participants whose tumors test positive for the
WT1 protein, will evaluate whether or when their mesothelioma recurs for a period of one
year after the vaccine treatment is completed. The principal investigator conducting the
study is thoracic oncologist Dr. Lee Krug, director of the Mesothelioma Program at Memorial
Sloan-Kettering. Dr. Krug can be contacted at 212-639-8420 or 646-888-4201.
The identifier number for the new mesothelioma clinical trial is NCT01265433. Researchers
expect the trial to be completed in December 2014.

3. Study of New Medicine for Mesothelioma Treatment
The National Cancer Institute is sponsoring a clinical trial of a
new medicine in hopes that it will help mesothelioma
patients whose cancers have been unresponsive to
chemotherapy. The trial is being conducted at the National
Institutes of Health’s Clinical Center in Bethesda, Md., and is
led by Dr. Raffit Hassan.
The experimental medicine that is being tested – IMC-A12 –
is a human antibody. The trial is a Phase II study, meaning the medicine has already shown
promise in preclinical testing in the laboratory and has been tested in people to assess
safety and proper dosage. The current research will continue to investigate safety and
evaluate IMC-A12′s effectiveness against mesothelioma tumors.
The medicine, also called cixutumumab, is given intravenously in the trial once every 21
days to patients with pleural mesothelioma (cancer in the thin layer of tissue that surrounds
the lungs and lines the chest cavity) or peritoneal mesothelioma (cancer in the lining of the
abdomen). The study is open to adults whose tumors can’t be fully removed with surgery,
and whose cancer has not responded to chemotherapy with drugs known as platinum-based
agents, such as cisplatin, which is commonly used to treat mesothelioma. Patients might
also be admitted if they have refused previous chemotherapy as part of their mesothelioma
treatment.
Treatment will be ongoing unless patients develop severe side effects or their mesothelioma
progresses. The primary goal is to see whether mesothelioma tumors partially or completely
respond to the medicine.
The antibody works somewhat in the way that glue gums up the works of a lock and
prevents a key from opening a door. IMC-A12 (the ―glue‖) stops up certain receptors
(―locks‖) that sit on the surface of a mesothelioma cell. That way, a protein called Type I
insulin-like growth factor, or IGF-1R—the normal ―key‖ that would open the door to the
cancer’s growth and survival – no longer works. This particular type of ―lock‖ and ―key‖ is
also being studied in other cancers.
All participants in the IMC-A12 trial must have acceptable kidney and liver function as well
as the adequate ability to form blood cells, and must not have had any major surgery,
radiation treatment, chemotherapy or biologic therapy within 28 days of the start of the
new mesothelioma treatment. Potential participants will be given a complete physical exam
to assess their mesothelioma and overall health.
Patients must cover their own travel expenses to be screened for possible enrollment in the
trial, but those selected to participate will receive payment for out-of-town transportation
costs for study treatment and follow-up. All medical care related to the trial will be provided
for free at the NIH Clinical Center, but patients should maintain any current health care
coverage to pay for other medical expenses.
Additional information about the mesothelioma study and its requirements can be obtained
from the cancer institute’s referral office, at 1-888-NCI-1937. The study’s identifying tag at
ClinicalTrials.gov is NCT01160458.

4. Mesothelioma and Gemcitabine
New research from Europe suggests that a drug known as gemcitabine, given along with one that
is now commonly used for mesothelioma, might someday serve as another weapon in doctors’
arsenals against the cancer.
Gemcitabine (marketed as Gemzar) is a chemotherapy drug currently in use to treat lung, breast,
pancreatic and ovarian cancers. In the recent, Phase II study—designed to test whether the drug
is effective and to measure side effects and other risks—investigators in Slovenia gave patients
with malignant pleural mesothelioma a prolonged, low-dose infusion of gemcitabine in
combination with cisplatin (marketed as Platinol).
The researchers decided to test this course of therapy against malignant pleural mesothelioma—a
cancer in a layer of specialized cells, called mesothelial cells, that line the chest and are adjacent
to the lungs—after noting that the treatment appeared to be effective in advanced cases of the
most common type of lung cancer, non–small-cell lung cancer.
Patients in the mesothelioma study were eligible if they had not previously received any
chemotherapy, and other than the mesothelioma, were in fair to good health with normal liver
and kidney function. The treatment entailed six three-week cycles of therapy. For the first four
cycles, patients received six-hour infusions of gemcitabine on the first and eighth days, plus
cisplatin on the second day; the last two cycles included the gemcitabine but not the cisplatin. A
total of 78 patients—58 men and 20 women, ages 33 to 82 years old—participated. More than 70
percent of the patients had mesothelioma tumors of the most common subtype, known as
epitheloid, a categorization based on certain characteristics of the cancer cells.
Four of the patients, or 5 percent, showed a complete response—meaning their cancer was
undetectable—after the therapy. Thirty-five had a partial response—meaning the size of their
tumors was reduced substantially. Another 35 patients had tumors that either responded
minimally or remained stable, while only four patients experienced tumor progression during the
treatment.
Sixty-seven percent of the mesothelioma patients survived one year after therapy; almost 33
percent survived two years, and about 20 percent survived three years. Patients who had
epitheloid tumors were more likely to survive longer without their tumor progressing, and to
survive longer overall, compared with patients who had other tumor subtypes.
Most of the patients experienced an improvement in mesothelioma symptoms, and a quality of
life that either remained the same or improved, the researchers reported. Notable side effects
included neutropenia (a shortage in a type of white blood cells, which can impair the immune
system), anemia (a shortage of red blood cells, which can cause fatigue) and hair loss, as well as
thrombocytosis (an excess of blood platelets, which cause clotting). Because the therapy
appeared to slow down the mesothelioma’s progress and didn’t prove to be too toxic, the
scientists advised that this mesothelioma treatment approach warranted further research.

5. Photodynamic therapy for pleural mesothelioma
A combination therapy might hold promise for
extending the lives and preserving more lung
function of patients with malignant pleural
mesothelioma, a cancer of the lining inside the
chest.
Patients in mesothelioma treatment often undergo
an extensive surgery known as a modified
extrapleural pneumonectomy, which involves
removal of the lung and surrounding tissue and is
usually accompanied by radiation of the whole
chest area. But the new combination approach for
mesothelioma patients adds a treatment called
photodynamic therapy to a more conservative,
lung-sparing surgery called a pleurectomy.
Photodynamic therapy is a light-based treatment that is designed to eliminate any microscopic bits of
residual cancer that surgeons are unable to remove. The therapy, which penetrates just a few
millimeters into tissue, has three components that are administered: a nontoxic compound that
sensitizes cancer cells to light; then oxygen; then specially tailored light. While the therapy is federally
approved for treatment of several cancers, it remains experimental for malignant pleural
mesothelioma.
Researchers at the University of Pennsylvania in Philadelphia set out to determine whether the lung-
sparing surgery could be used instead of an extrapleural pneumonectomy, and whether the use of
photodynamic therapy would extend patients’ survival time, compared with typical survival times in
mesothelioma patients.
Nine women and 19 men with malignant pleural mesothelioma, ranging in age from 27 to 81,
participated in the Phase II study from 2004 to 2008. Half received the more extensive surgery along
with photodynamic therapy, while the other half had the lung-sparing surgery along with the light-
based therapy.
Twelve patients in each group had stage III/IV mesothelioma—and researchers noted that many of
the research subjects, due to the advanced stage of their mesothelioma or to their advanced age,
would not be candidates for surgical treatment. In all, 22 patients also had chemotherapy. The two
groups were comprised of mesothelioma patients with similar demographic traits such as age, sex and
disease characteristics.
Among the patients who had the more extensive surgery and photodynamic therapy, the median
overall survival—the point in time after treatment was completed at which half the patients were still
alive—was 8.4 months. For the patients receiving the lung-sparing surgery plus the light therapy, that
median point had not been reached yet, after more than two years of follow-up.
The surgeon who performed the procedures in the study, Dr. Joseph Friedberg of the Penn
Mesothelioma and Pleural Program, said researchers had hoped that preservation of patients’ lungs
would improve their quality of life, and that the extended survival time of those patients was a
complete surprise. The scientists are continuing to investigate exactly how the photodynamic therapy
might be helping to fight mesothelioma—possibly by creating a ―vaccine‖ effect with residual disease
that sparks the immune system to fight any remaining cancer. Or, the photodynamic therapy might
have made any residual cancer more vulnerable to other follow-up treatments.

6. SIDE EFFECTS OF CHEMOTHERAPY ON MESOTHELIOMA PATIENTS
While doctors might choose from an assortment of
available medicines to care for
malignant mesothelioma patients, a combination
treatment with two chemotherapy drugs—pemetrexed
disodium (marketed as Alimta) and cisplatin (marketed
as Platinol)—is a mainstay. The two drugs are typically
used in patients when surgery is not an option.
Pemetrexed received approval from the federal Food and
Drug Administration (FDA) in 2004 for the treatment of
malignant pleural mesothelioma, a cancer of the chest
cavity lining, after a randomized clinical trial showed that
the drug, given with cisplatin, extended patients’ average
survival time longer than cisplatin alone. As the first drug
shown to be effective against pleural mesothelioma,
pemetrexed received priority review from the FDA.
As with most chemotherapy treatments, mesothelioma patients are vulnerable to experiencing side
effects from the combination of pemextrexed and cisplatin. In more than half the patients in the
clinical trial, the treatment suppressed bone marrow function, which might lead to low counts of white
blood cells, the body’s infection fighters. It’s important that mesothelioma patients on pemetrexed and
cisplatin tell their doctors immediately about any signs of infection, such as fever or chills or mouth
ulcers. Vitamin B-12 and folic acid are administered with pemetrexed to reduce the risk of a low white
cell count, as well as the likelihood of other side effects.
Cisplatin and pemetrexed also lowered red blood cell counts in about one-quarter of the mesothelioma
patients in the clinical trial. This condition, known as anemia, can cause fatigue. Medicines are
available to treat both low white and low red blood cell counts. Also, research has shown that
moderate exercise can help reduce cancer patients’ fatigue, and perhaps lessen pain.
Mesothelioma patients on pemetrexed could also experience a drop in their platelet count. Platelets
help the blood to clot, and patients with reduced levels of platelets should report any signs of
bleeding. These patients also might be asked to take precautions to avoid even minor injuries that
might cause bleeding, such as using a soft toothbrush to prevent gum bleeding.
Nausea and vomiting are very common side effects of the pemetrexed-cisplatin combination;
fortunately, effective anti-nausea medicines can be prescribed. Patients should promptly tell their
doctors about those symptoms—as well as rash, diarrhea, constipation, sore or gritty eyes and other
health concerns. It’s important that mesothelioma patients keep their health care teams fully informed
of side effects and avoid choosing over-the-counter treatments without medical consultation.
