NEW MEDICAL ACHIEVEMENT FOR THE CURE OF KIDNEY CANCER: FDA approves Opdivo to treat advanced form of kidney cancer
The U.S. Food and Drug Administration today approved
Opdivo (nivolumab) to treat patients with advanced (metastatic) renal cell carcinoma,
a form of kidney cancer, who have received a certain type of prior therapy.
“Opdivo provides an important therapy option for patients
with renal cell carcinoma,” said Richard Pazdur, M.D., director of the Office
of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and
Research. “It is one of few therapies that have demonstrated the ability to
extend patients’ survival in treating this disease.” Torisel (temsirolimus), approved in 2007, is the only other
FDA-approved therapy that has demonstrated overall survival in renal cell
cancer.
Renal cell carcinoma is the most common form of kidney
cancer in adults and forms in the tissues of the kidney that make urine. The
National Cancer Institute estimates 61,560 new cases and 14,080 deaths from
kidney and renal pelvis cancer in the United States this year.
“Additionally, Opdivo’s extended indication, from
melanoma and non-small cell lung cancer to renal cell cancer, demonstrates how
immune therapies can benefit patients across a wide range of tumors,” continued
Dr. Pazdur.
Opdivo works by targeting the cellular pathway known as
PD-1/PD-L1 (proteins found on the body’s immune cells and some cancer cells).
By blocking this pathway, Opdivo may help the body’s immune system fight cancer
cells. Opdivo is intended for use in renal cell carcinoma in patients who have
received prior anti-angiogenic therapy (treatments that interfere with the
blood vessels that contribute to the growth of cancerous cells).
The safety and efficacy of Opdivo for this use were
demonstrated in an open-label, randomized study of 821 patients with advanced
renal cell carcinoma whose disease worsened during or after treatment with an
anti-angiogenic agent. Patients were treated with Opdivo or another type of
kidney cancer treatment called everolimus (marketed as Afinitor). Those treated
with Opdivo lived an average of 25 months after starting treatment compared to
19.6 months in those treated with Afinitor. This effect was observed regardless
of the PD-L1 expression level of patients’ renal cell tumors. Additionally,
21.5 percent of those treated with Opdivo experienced a complete or partial
shrinkage of their tumors, which lasted an average of 23 months, compared to
3.9 percent of those taking Afinitor, lasting an average of 13.7 months.
The most common side effects of Opdivo for this use are
conditions relating to abnormal weakness or lack of energy (asthenic
conditions), cough, nausea, rash, difficulty breathing (dyspnea), diarrhea,
constipation, decreased appetite, back pain and joint pain (arthralgia).
Opdivo also has the potential to cause serious side
effects that result from the immune system effect of Opdivo (known as
“immune-mediated side effects”). These severe immune-mediated side effects
involve healthy organs, including the lung, colon, liver, kidneys,
hormone-producing glands and the brain.
The FDA granted the Opdivo application a breakthrough therapy designation, fast track designation, and priority review status. These are distinct programs
intended to facilitate and expedite the development and review of certain new
drugs in light of their potential to benefit patients with serious or
life-threatening conditions.
Opdivo is marketed by Bristol-Myers Squibb based in
Princeton, New Jersey. Torisel is marketed by Pfizer, based in New York, New
York. Afinitor is marketed by Novartis Pharmaceuticals of East Hanover, New
Jersey.

VALUE-BASED CANCER CARE
Robert C. Young, M.D.
November 18, 2015DOI: 10.1056/NEJMp1508387
In
June 2015, the American Society of Clinical Oncology (ASCO) published a
proposed framework for assessing the value of various cancer treatments.1 The goal was to evaluate
selected treatment regimens on the basis of their clinical benefit, toxicity,
and cost. ASCO's ideas about cost had been incubating for a long time: the
organization had created a Task Force on the Cost of Cancer Care in 2007,
although, like most medical specialty organizations, it had generally remained
silent on the issue of cost. But the cost of cancer care has been growing
rapidly: though it accounts for a relatively small portion of overall U.S.
health care expenditures, it is expected to increase from $125 billion in 2010
to $158 billion in 2020.
The
costs of cancer drugs amount to only 5 to 20% of the total costs of cancer
care, depending on how many of the multiple cost components are included. But
the average cost of some newer cancer drugs is now $10,000 to $30,000 per
month, and combinations of checkpoint inhibitors cost as much as $100,000 per
month. Virtually none of these treatments are curative, and some improve only
disease-free survival, not overall survival. The costs of copayments,
out-of-pocket expenses, and rising insurance premiums exceed many patients'
capacity to pay. A 20% copayment for checkpoint inhibitors might cost the patient
$60,000 for a full course of treatment. Many patients elect to simply forgo
treatment.

MAYO RESEARCHERS FIND CANCER BIOPSIES DO NOT PROMOTE CANCER SPREAD
Mayo Researchers Find Cancer Biopsies Do Not
Promote Cancer Spread
JACKSONVILLE,
Fla. — A study of more than 2,000 patients by researchers at Mayo Clinic’s
campus, has dispelled the myth that cancer biopsies cause cancer to spread. In
the Jan. 9 online issue of Gut, they show that patients who received a biopsy
had a better outcome and longer survival than patients who did not have a
biopsy.
The image shows a pancreas tumor being biopsied with a
needle as visualized by endoscopic ultrasound. The endoscope was located within
the stomach (passed via the mouth). An ultrasound probe at the tip of the
endoscope allows visualization of the pancreas which is located immediately
next to the stomach. A long needle is guided through the endoscope and into the
tumor under ultrasound guidance.
The researchers
studied pancreatic cancer, but the findings likely apply to other cancers
because diagnostic technique used in this study — fine needle aspiration — is
commonly used across tumor types, says the study’s senior investigator and
gastroenterologist Michael Wallace, M.D.
Fine needle
aspiration is a minimally invasive technique that uses a thin and hollow needle
to extract a few cells from a tumor mass. A long-held belief by a number of
patients and even some physicians has been that a biopsy can cause some cancer
cells to spread.
While there
have been a few case reports that suggest this can happen — but very rarely —
there is no need for patients to be concerned about biopsies, says Dr. Wallace.
“This study
shows that physicians and patients should feel reassured that a biopsy is very
safe,” he says. “We do millions of biopsies of cancer a year in the U.S., but
one or two case studies have led to this common myth that biopsies spread
cancer.”
Biopsies offer
“very valuable information that allow us to tailor treatment. In some cases, we
can offer chemotherapy and radiation before surgery for a better outcome, and
in other cases, we can avoid surgery and other therapy altogether,” Dr. Wallace
says.
Surgery for
pancreatic cancer is “a very big operation,” and “most people should want to
make sure they have cancer before they undergo surgery,” he says. One study has
shown that 9 percent of patients who underwent surgery because of suspected
pancreatic cancer actually had benign disease.
Dr. Wallace and
his team have conducted two separate studies to examine the risk of biopsy.
In a 2013 study
published in Endoscopy,
the researchers examined outcomes in 256 pancreatic cancer patients treated at
Mayo Clinic in Jacksonville, Florida. They found no difference in cancer
recurrence between 208 patients who had ultrasound-guided fine needle
aspiration (EUS-FNA) and the 48 patients who did not have a biopsy.
In the current
study, they examined 11 years (1998–2009) of Medicare data on patients with
non-metastatic pancreatic cancer who underwent surgery. The researchers
examined overall survival and pancreatic cancer-specific survival in 498
patients who had EUS-FNA and 1,536 patients who did not have a biopsy.
During a mean
follow-up time of 21 months, 285 patients (57 percent) in the EUS-FNA group and
1,167 patients (76 percent) in the non-EUS-FNA group died. Pancreatic cancer
was identified as the cause of death for 251 patients (50 percent) in the
EUS-FNA group and 980 patients (64 percent) in the non-EUS-FNA group.
Median overall
survival in the EUS-FNA group was 22 months compared to 15 months in the
non-EUS-FNA group.
“Biopsies are
incredibly valuable. They allow us to practice individualized medicine —
treatment that is tailored for each person and designed to offer the best
outcome possible,” Dr. Wallace says.

A SIMPLE TECHNIQUE MAY BE MOST EFFECTIVE IN PREVENTING HEART DISEASE AFTER RADIATION THERAPY FOR BREAST CANCER
Women who have breast cancer
on their left side present a particular challenge to radiation oncologists.
Studies have shown that the risk of heart disease is higher in this group of
women after radiation treatment because it can be difficult to ensure that a
sufficient dose of radiation is delivered to the left breast while adequately
shielding the heart from exposure. New research shows a woman who holds her
breath during radiation pulses can greatly reduce radiation exposure to the
heart.
"Radiation therapy is commonly
prescribed to patients with breast cancer following surgery as a component of
first-line therapy," said first author Harriet Eldredge-Hindy, M.D., a
Chief Resident and researcher in the Department of Radiation Oncology at Thomas
Jefferson University "We wanted to determine how effective breath-hold
could be in shielding the heart from extraneous radiation exposure during
treatment of the left breast."
Recent studies have shown women
with cancer in the left breast are at higher risk of heart disease, and that
the risk increases proportionately with the dose of radiation the heart is
exposed to during treatment. A number of techniques have been developed to
reduce exposure to the heart including prone positioning (lying flat on the
belly on a bed that only exposes the left breast), intensity-modulated
radiation therapy (IMRT), and accelerated partial breast irradiation. The
breath-hold technique allows doctors to monitor a patient's breath for the
position that shifts the heart out of the range of the radiation beam.
In the largest prospective study to
date, following women for 8 years post treatment, 81 women were asked to hold
their breath during radiation treatment for breast cancer- a process that was
repeated until therapeutic dose was reached. The researchers found that
patients capable of holding their breath over the course of treatment had a 90
percent disease-free survival, and a 96 percent overall survival, with a median
reduction in radiation dose to the heart of 62 percent. The findings were
published online this week in the journal Practical Radiation Oncology.
"Given that this technique helps to shield the
heart during radiation treatment for breast cancer," said Rani Anne, M.D.,
Associate Professor of Radiation Oncology at Thomas Jefferson University and senior
author on the study, "we routinely offer breast cancer treatment with the
breath hold technique at Jefferson."
