C002D5556 Sunday 08 April 2018 46BDSUNDAY Health&Science New immunotherapy for lung cancer shows promise of success Immunologist John Wrangle, M.D., of the Hollings Cancer Center at the Medical University of South Carolina said it’s a promising therapy that can be delivered in an outpatient setting. “People don’t talk about ‘curing’ patients with metastatic lung cancer. We now get to flirt with the idea for certain patients using immunotherapy. And at the very least we have a significant proportion of patients enjoying prolonged survival even if we can’t call them ‘cured’,” he said. He, along with his colleague Mark Rubinstein, Ph.D. also of the Hollings Cancer Center, designed a clinical trial that started in 2016. Patients with metastatic nonsmall cell lung cancer will always progress after chemotherapy, so most patients go on to be treated with immunotherapy, a type of therapy that uses the body’s immune system to fight cancer. One class of immunotherapeutic drugs is known as “checkpoint” inhibitors, as they target checkpoints in immune system regulation to allow the body’s natural defenses, such as white blood cells, to more effectively target the cancer. Rubinstein said checkpoint therapies work by cutting the brake cables on the white bloods cells that are inherently able to kill tumor cells. “Tumor cells often produce suppressive factors which essentially turn the brakes on tumor-killing white blood cells. What’s unique about the therapy that we’re testing is that in addition to cutting the brake cables on white blood cells, we’re providing fuel to them so that they can more effectively kill cancer cells.” Wrangle and Rubinstein’s therapy is a combination of a checkpoint drug, nivolumab, with a new and powerful immune stimulation drug, ALT-803. “What’s unique about our trial is that it’s two completely different types of drugs that have never been combined in humans before, and the trial demonstrated that these drugs can be safely administered, and also, there’s evidence that it may help patients where checkpoint therapy is not good enough alone,” said Rubinstein. Patients who have stopped responding to checkpoint therapy may be helped significantly by adding ALT-803. Pre-clinical studies have shown that ALT-803 activates the immune system to mobilize lymphocytes against tumor cells and could potentially serve as an important component in combination treatments. Of the 21 patients treated, nine previously either had stable disease or responded to single-agent immunotherapy before becoming resistant to this treatment. Of these nine patients, 100 percent either had stable disease or had a partial response to the treatment used in this study. “We can reassert control, at least in terms of stable disease, in essentially everybody we’ve treated so far,” Wrangle said. This novel combination is a huge step forward in cancer treatment. “Whereas for de- cades the modalities of therapy were surgery, radiation, and chemotherapy, the last decade has brought targeted therapy, and more recently, immunotherapy. It fundamentally alters the balance of power between your body and your cancer,” Wrangle said. A lung cancer specialist, Wrangle said 75 percent of lung cancer patients unfortunately are diagnosed at an incurable stage. “If 10 years ago you were talking about defining a five-year survival rate for metastatic nonsmall cell lung cancer patients, someone would laugh in your face. It would be a joke. It’s just a very different time now,” he said of the progress being made in the treatment of lung cancer. Wrangle explained that natural killer cells are the chief arm of the innate immune response. “They are an important part of anti-cancer response that haven’t been really talked about for a long time.” Wrangle said his collaboration with Rubinstein is a powerful example of what team science can accomplish. “His ownership of the intellectual foundation of this therapy is manifest,” Wrangle said of Rubinstein’s contribution. “He is brilliant and just works furiously to help understand how we can develop this therapy.” Successful trials for the treatment of cancer are incredibly rare, he said. “There are very few people in human history who get the privilege of developing a new therapy for any human disease, much less cancer. Mark and I are now in this weird micro-club of folks who have developed the promise of a new therapy for cancer. That’s such an amazing privilege to be able to do that,” he said. Both of the researchers, who are in their early forties, said they were motivated by the need to give lung cancer patients better options. Wrangle plans to frame the study’s publication. “I think this manuscript will be the thing that we have on the wall that we look back at 20 years from now, when we’re still working together and discovering new therapies.” -Medical University of South Carolina Excessive stress may relapse to mental illness ANTHONIA OBOKOH An expert in Psychology has said that excessive stress may relapse to mental illness. According to reports, the Federal Neuro-Psychiatrist Hospital, Yaba, Lagos, witnessed a 111 per cent increase in overall patient attendance and 59 per cent increase in number of new patients from January –November 2016. In absolute figures, according to the data, there was an overall 46 per cent increase in number of admissions in 2016 (867) compared to 594 in 2015, while the community clinic attendance went up from 1,793 to 3,510, a 95 per cent increase. Richard Adebayo, a consultant psychiatric and clinical psychologist, at Federal neuropsychiatric hospital, Yaba, Lagos in an interview with BusinessDay said that relapses can have overwhelming consequences for people with mental disorders such as schizophrenia, bipolar disorder, depression, or an anxiety disorder. “We know here that a patient can easily relapse into mental illness when they are undergoing severe stress. “Stress is one of the common causes of a relapse including drug and alcohol misuse, lack of sleep or irregular pattern of sleep, lack of social relationships and support, poor understanding of your mental disorder in general. Addressing these factors may help you to prevent a full-scale relapse” Adebayo said. Adebayo added that understanding the psychological mechanisms of how stress can lead to depression and anxiety can help prevent it. This is especially important for people who have had an earlier episode of depression or who have a genetic tendency of coming down with mental disorders and would like to prevent relapse. “Stress is an everyday event that human beings pass through due to excessive pressure and it can translate into deeper health implications on both physical and mental consequences either positively or negatively. Adebayo further explained that when an individual is undergoing stress, the body metabolism could be affected and the hormones get disrupted making the alert system in the body, the adrenaline and non-adrenaline to be on the hyper level because the person is always agitated. He added that some people use wrong coping strategy, when they are stressed up, smoking cigarettes, drinking alcohol. Many Nigerians falls in this category, thinking these wrong strategies will ease them of stress at home, work place. “These are wrong coping strategies, taking alcohol will not solve the stress but some people believe that is an escape route to forget problems. “Your kind of coping strategy when stressed is very important, but we should not adhere to wrong lifestyles.” Adebayo advised.
