Immunotherapy as Effective Second-Line Treatment for Mesothelioma

Effective Second-Line Treatment for Mesothelioma

A study from Taiwan has identified an effective second-line treatment for malignant pleural mesothelioma.

When a patient is diagnosed with mesothelioma and begins treatment, the first treatment is called the “first-line treatment.” If that treatment does not work or stops working, a “second-line treatment” is given to the patient.

For mesothelioma, treatment usually consists of surgery, chemotherapy, and radiation. The exact treatment plan will depend on many factors. Doctors will consider the type of mesothelioma, the condition of the patient, and how much the cancer has spread.

A common first-line treatment for mesothelioma patients is chemotherapy with drugs called pemetrexed and cisplatin. When this treatment works properly, it stops cancer cells from growing and multiplying. It is for patients whose disease is either inoperable or who are not candidates for surgery.

When pemetrexed and cisplatin fail to stop cancer growth, the second-line treatment is hotly debated in the medical world. There is ongoing research into other chemotherapy drugs, immunotherapy, and different anti-cancer treatments.

The researchers in this study from the journal Cancers aimed to identify a good second-line treatment for malignant pleural mesothelioma.

Immunotherapy as Second-Line Treatment

The researchers looked at data they found from 11 published studies. These studies compared different types of second-line treatments. The researchers looked at the overall survival rates of these treatments.

An immunotherapy treatment with nivolumab alone or with ipilimumab had the best survival rates.

Immunotherapy is a type of cancer treatment that uses the patient’s immune system to fight their cancer. The drugs nivolumab and ipilimumab are called immune checkpoint inhibitors. One of these drugs increases the number of cancer-killing immune cells in a mesothelioma tumor. The other drug alters mesothelioma cells to make them more susceptible to attack.

Research like this can help doctors to make treatment decisions for patients that will help them recover from cancer. This is especially important for mesothelioma, which can be aggressive and hard to treat.

Doctors Describe "Concrete Therapeutic Approach" for Mesothelioma

A team of medical researchers in Italy have achieved what they are calling “excellent” tumor control and survival results in malignant pleural mesothelioma patients using a combination of surgery, chemotherapy, and radiotherapy. Caused by exposure to asbestos, mesothelioma typically spreads quickly across the lung-encasing membrane called the pleura. There is no known cure but treatments are improving. In the current prospective study, 20 malignant pleural mesothelioma patients underwent radical pleurectomy/decortication followed by high doses of radiation. After surgeons removed as much of the visible mesothelioma tumor and surrounding tissue as possible, patients received 50Gy of radiation to the effected side of their chest, delivered in 25 fractions. Regions of particular concern for mesothelioma regrowth got an extra radiation “boost” to…

Does Radiotherapy Reduce Mesothelioma Pain?

ByAlex Strauss

A new study says there is not enough evidence to support the use of radiotherapy for the treatment of pain associated with malignant pleural mesothelioma. Researchers at the University of Edinburgh in Scotland reviewed a range of past studies on mesothelioma pain and radiotherapy by searching databases that date back as far as 1974. To be eligible to be included in their review, the study had to focus on malignant pleural mesothelioma and radiotherapy given “with the intent of improving pain”. The study also had to report doses and fractionation of the radiotherapy and how the pain responded. In all, the researchers found eight studies on mesothelioma pain and radiotherapy that met the criteria. Two of the studies were prospective…

Radiotherapy for Mesothelioma: Better But Still Limited

ByAlex Strauss

A form of highly-targeted radiation therapy for mesothelioma is better than it used to be, but is still risky. That is the message of a recent article on intensity-modulated radiation therapy (IMRT) in Seminars in Thoracic and Cardiovascular Surgery. Author Kenneth E. Rosenzweig, MD, a Radiation Oncologist with Mount Sinai Hospital in New York, reviewed recent studies on IMRT and mesothelioma. He concludes that, while the “troubling toxicity” associated with IMRT when it was first introduced has not been entirely eliminated, the fact that clinicians now have more experience with it is making a positive difference for mesothelioma patients. Before targeted therapies like IMRT were available, high-dose radiation was not usually a feasible option for mesothelioma since the irregular shape…

A Second-Line Option for Mesothelioma?

ByAlex Strauss

Although survival was not significantly extended, the chemotherapy drug vinorelbine might be a treatment option for mesothelioma patients whose cancer has returned after first-line chemotherapy with pemetrexed. A new study on vinorelbine as a second-line treatment finds that the drug is “moderately active” in mesothelioma patients who were initially treated with pemetrexed-based chemotherapy. Pemetrexed (Alimta), along with a platinum-based drug like cisplatin, is the primary first-line drug therapy for mesothelioma. But vinorelbine is gaining attention as a possible option for mesothelioma, in part because it is available in a less expensive generic form. In “Vinorelbine in pemetrexed-pretreated patients with malignant pleural mesothelioma”, the Italian authors detail the results of their study on 59 patients with unresectable pleural mesothelioma.  These patients…

Repeat HIPEC Improves Mesothelioma Survival

ByAlex Strauss

If one cytoreductive surgery and HIPEC procedure for mesothelioma is good, subsequent treatments may be even better. That is the central message of research conducted at the Moffitt Cancer Center in Florida. The study’s aim was to assess overall survival among peritoneal mesothelioma patients who had not just one, but two or more rounds of heated intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery. The cytoreduction/HIPEC approach has become popular for peritoneal mesothelioma, a treatment-resistant cancer of abdominal membranes caused by asbestos. Cytoreductive surgery involves removing as much of the mesothelioma tumor as possible from the abdomen. Because the shape and spreading pattern of mesothelioma tumors make complete cytoreduction difficult, the surgery is often followed by a rinse with a heated solution…

Value of Mesothelioma Surgery Challenged for Healthy Patients

ByAlex Strauss

New research conducted in Italy and presented at the 15th World Conference on Lung Cancer in Sydney, Australia suggests that mesothelioma surgery – no matter what kind – may not offer a survival advantage over medical management for the healthiest of patients. Mesothelioma is a rare but aggressive malignancy that is highly resistant to standard cancer treatments. The two types of mesothelioma surgery considered to be options for people with resectable cancer are pleurectomy decortication (P/D) or extrapleural pneumonectomy (EPP). While EPP is more radical than P/D because it involves removing a lung, both carry a heavy risk of complications and, according to the Italian researchers, may not be of value for certain patients. The study reviewed data from 1,365…
