Cancer Immunotherapy Use on Cancer Patients

Recent advances in treating cancer patients have resulted in the development of biological therapies that can prove to be a promising alternative to conventional cancer therapies. Immunotherapy harnesses the body’s immune system to identify and fight effectively against cancer cells.

Immunotherapy works by attacking the growth of cancer cells or stimulating the immune system to kill cancer cells. Contradictory to the standard cancer treatment regimes such as chemotherapy, radiation therapy, which act on both normal and cancerous cells, immuno-therapeutic treatments are highly specific. A wide range of cancer immuno-therapy approaches exists such as immune checkpoint blockers, cancer vaccines, immune-modulators, monoclonal antibodies and cell based immuno-therapies have demonstrated to be effective against cancer patients.

The most commonly targeted form of cancer chemotherapy is the use of monoclonal antibodies as they can be tailor-made in the laboratory. They have unique antigen specificity thereby allowing themselves to attach to specific epitopes on cancer cells. This flags the cancer cells and makes it more visible to the immune system so that it can find and destroy those cells. Currently, most of the monoclonal antibodies are undergoing phase 3 clinical trials or awaiting FDA review process. Unlike monoclonal antibodies, non-specific immuno-therapy approaches such as administration of immuno-modulatory cytokines are also being used to treat melanoma. Cytokines are hormones that are endogenously produced by the body to enhance or suppress T-cell response against cancer cells. IFN-α and IL-2 are most commonly characterized cytokines used in cancer immuno-therapy.

The primary cell-based immuno-therapy strategy which is successful these days is the use of T-cell therapy, wherein cancer T cells removed from blood are modified with chimeric antigen receptor (CAR) and is then infused back into the patients to treat metastatic cancer. Another form of cell-based immuno-therapy used is tumor-infiltrating lymphocytes (TIL) therapy, wherein TIL is surgically removed from tumor tissue and is considerably increased in the laboratory by adding cytokines to it and is then re-infused back into the patient.

A promising treatment that has emerged in recent times for treatment of melanoma is the use of immune checkpoint inhibitors. They act by inhibiting the checkpoint receptors on T cells that act as brakes to the immune system thereby mediating anti-tumor responses. Some of the commonly used antibody inhibitors that have been commercialized are PD-1, PDL-1, and CTLA-4. Another more focused approach to cancer immuno-therapy is the use of vaccines to encourage the immune system to generate antibodies that can target tumor specific antigens, thereby eradicating cancerous cells. Cancer vaccines include peptide-based, dendritic cell-based, tumor cell-based and DNA cell based. Cancer vaccines can be broadly classified as preventive or therapeutic. Preventive vaccines are commercially available for against cervical and liver cancer causing viruses such as human Papillomavirus and Hepatitis B virus, respectively.

However, in spite of these advances, limitation such as tumor heterogeneity, unpredictable efficacy and identification of potential markers still exist in the field of cancer immuno-therapy. Therefore, new more targeted cancer immuno-therapies and preventive strategies are being developed and tested, which will deliver novel efficacious therapy against relapsed or refractory cancer patients.

Good,, Bad, and Trans Fats and the Health Risk They Pose

What many don’t realise is that fats are essential for good health. The brain, for instance, is contains fat, but it is the good one and not that which can kill you. As people age they become more susceptible to weight gain and the large stomachs seen in many. The fat around their middle is from bad fats that usually come from things like sugar and trans fats.

Alcohol is the same as sugar in its molecular component. In other words, sugar breaks down into the same structure as alcohol and this is why beer drinkers end up with what is described as a ‘beer gut’. But that is not trans fat but the product of a normal digestive function whereby the ‘sugar’ overloads the liver and turns into fat.

In that case one may end up with a fatty liver and possibly pancreas leading to cancer of the organs. It also leads to diabetes and loss of limbs, eye-sight, and heart disease, among other things.

Then there are the trans-fats and these are normal fats that have undergone transformation due to heat. They take on extra molecules of hydrogen during the process and that makes them virtually indigestible by the liver so that they are laid around the vital organs.

The worst practice comes from super heated and oft heated oils. They are found in commercial ovens where deep fried fish and vegetables are produced. They are the in many of the snack foods people are addicted to while the warning that should accompany them is that they can lead to diseases, as described above, and even death.

The Present and Future of Radiotherapy

The radiotherapy market is growing due to several factors, such as an increase in the number of new cancer cases and technological advancement in the hardware and software used in radiotherapy. The current international markets are underequipped to address new cases of cancer. In low- and middle-income countries, only 10% of the population has access to radiotherapy. Therefore, there exists a wide gap between the demand and the installed base of equipment, which offers a huge opportunity for the companies to grow in the radiotherapy market. Expansion of the radiotherapy market can be both lifesaving and profitable.

Effective planning for the treatment

It is necessary, and continuous technological developments are taking place to minimize the exposure to radiation of healthy tissue, in order to avoid any side effect. This goal is a driving force of R&D for radiotherapy. Software plays an increasingly significant role in cancer care. Population growth and increased life expectancy are adding to the incidences of cancer. The software & services segment includes software, which is used for treatment planning, analysis, and services, which are needed for the maintenance and efficient use of radiotherapy devices. The software & services segment of the companies are expected to grow, as software products help improve physician engagement and clinical knowledge-sharing, patient care management, and the management of cancer clinics, radiotherapy centers, and oncology practices for better performance. Companies like Varian are continuously increasing their software portfolio. Software plays an increasingly significant role in cancer care. At the same time, healthcare systems are subject to harsh budgetary constraints in nearly every country. As a result, healthcare providers face the challenge of achieving more while using fewer resources. To achieve this goal, hospitals have a strong need for software platforms that make radiotherapy treatment cost-effective. The development of effective software will improve the delivery of advanced radiotherapy in the future.

Introduction of new technology
Technology is another salient feature. Radiation therapy remains a significant modality for cancer treatment, which is the primary driving factor for the designing of new techniques to improve the survival rate of cancer patients. New technologies, like proton beam therapy, are available in developed countries like the United States, Germany, and United Kingdom, due to well-established reimbursement policies. Proton therapy can be used on tissues that are highly sensitive, like brain, spine, and eye tumors. It is more accurate, as compared to other X-ray radiation therapies.

Advancement in the technology is also helping to execute the planning of the radiation therapy.

Technological advancement in existing technologies, such as CT imaging, is making imaging more accurate and consistent. This can give a better representation of a tumor and help in better planning. Already-existing technology, such as IMRT, SBRT, IGRT, conformal 3D, VMAT, and others that are used for radiation therapy treatment is undergoing various advancements. For example, Varian is developing a software, which can be used to develop better planning tools, in which statistical models can be used to calculate the quality of an IMRT treatment for a patient. This is expected to increase the usage of IMRT for treating cancer. IGRT is the type of radiotherapy. Research is more focused on IGRT, in order to prove its fewer side-effects. IGRT may include electronic portal imaging, fluoroscopy, ultrasound, CT scan reconstruction, and respiratory gating technology. SBRT is also growing as an option for treating cancer. SBRT is used to escalate the dose to the targeted tumor, which can increase local control while limiting the dose to nearby critical structures and normal tissues. This will cause minimum damage to the surrounding tissues and hence, will experience strong growth in the forecast period.

The Life of Mammogram Inventor Stafford L Warren

Stafford L. Warren was one of the most significant contributors to radiology during his lifetime. He not only was the first doctor to perform a mammogram, but was also had a hand in turning UCLA into one of the most prestigious medical universities in the country, was a special assistant on mental disabilities to Presidents John F Kennedy and Lyndon B Johnson, and aided the U.S. government in testing of nuclear weapons before speaking out about the dangers of nuclear fallout from weapons testing, which were controversial at the time. However, his strong opinions would eventually be considered, leading up to the Partial Nuclear Test Ban Treaty in 1963.

Born in New Mexico in 1896, Stafford L. Warren attended the University of California, Berkeley, and graduated with his Bachelor of Arts degree in 1918. Heading to the University of California, San Francisco, he graduated with his Doctor of Medicine degree in 1922 and later did post-doctoral work at John Hopkins School of Medicine and Harvard University.

Warren became an Assistant Professor of Medicine at the University of Rochester School of Medicine in 1926. Since the Department of Radiology was brand new at the time, Warren was one of the original group of medical professionals that Dean George Whipple chose to staff the school. By 1930, Warren was an Associate Professor of Medicine. He began to study the work of Albert Salomon, a sociologist from the University of Berlin who produced over 3,000 images of mastectomy specimens and extensively studied the many forms and stages of cancer in the breast. Since Salomon wasn’t keen to recognize the life saving aspects of his discoveries, Warren expanded on his research, using radiology to track changes in breast tissue and developing a stereoscopic technique in which the patient would lie on her side with one arm raised while being X-Rayed. This was a huge breakthrough for breast cancer detection, as it allowed diagnosis of breast cancer to be possible without surgery. Warren subsequently published “A Roentgenologic Study of the Breast” in 1930. Today Warren is cited as the inventor of the mammogram for his breast imaging technique. Each year mammograms are responsible to diagnosing millions of breast cancer cases, effectively saving the lives of women the world over.

Warren, having now tackled a major milestone in his career and developing a new life saving technique, then went on to take on a new project: overseeing the health and safety of thousands during the Manhattan Project. His new role meant being responsible for the safety aspects of the detonation of the Trinity nuclear test in Alamogordo, New Mexico on July 16, 1945. He later handled radiological safety when he led a team of surveyors to Japan, and to the Bikini Atoll in 1946, where more nuclear testing was done. Warren was in charge of assessing the radioactive contamination of the environment and atmosphere, which he was appalled by.

In response to this, in a piece for LIFE magazine in 1947 he wrote, “The development of atomic bombs has presented the world with a variety of formidable scientific, moral and political problems, nearly all of them still unsolved.” He went on to write an in depth analysis of the effects of the bombs, people and environment affected, the time length in which the effects of the bomb lasted, safety measures used during the Bikini expedition in which “a month passed before men could stay on some of the ships for more than an hour”, and “300 men of the safety section lived and worked in the contaminated area to protect some 42,000 other members of the Bikini expedition. Every group which entered the target area was accompanied by a safety monitor who determined how long it could stay.” The men were then bathed carefully when they returned, and if their Geiger counters indicated radioactive contamination they had to be bathed again. “Occasionally when a man had taken off his protective gloves in the ‘hot’ area, the safety section had to dissolve the outer layer of skin from their hands with acid.” Clothes and other materials found too contaminated were sunk into the ocean a mile below the surface, because there was literally “no other way to keep them permanently away from human beings.”

In the article, Warren concluded that atomic weapons can never be prepared for by anyone involved, and that “no defense would have been effective. The only defense against atomic bombs still lies outside the scope of science. It is the prevention of atomic war.”

Warren left his position in 1946, becoming the Chief of the Medical Section of the Atomic Energy Commission, which is a civilian agency that succeeded the Manhattan Project; and later he was awarded the Army Distinguished Service Medal and the Legion of Merit for his contributions to radioactive and atomic weapons safety.

In 1947, Warren was once again at the helm of a brand new medical university, this time UCLA, which had been voted on to establish a medical school for Southern California. He was appointed as the school’s first dean. In 1951 the first students, 28 in total, were enrolled, and there were 15 faculty members. By 1955, when the class graduated, there were 43 faculty members. The UCLA Medical Center officially opened in 1955, and Warren oversaw many milestones and achievements while there, including the addition of schools for Dentistry, Nursing, and Public Health.

Analysis to Next Generation Sequencing Technology

With the development of science, traditional Sanger sequencing has failed to meet new requirements of low cost, high throughput and fast in speed.

Recent years, with the discovery and promotion of second-generation sequencing technology, the gene sequencing speed has increased greatly while achieving a substantial decline in costs, making large-scale application of genome sequencing possible. Now, the cost of personal whole genome sequencing is about 5,000$, and is expected to decreased to less than $ 1,000 in the next few years.

The rapid development of sequencing technology will promote the massive accumulation of DNA sequencing data, accompanied by the accumulation of the corresponding individual diseases, signs and other data at the same time. When we accumulate enough data, how to understand these data will be critical. On the micro level, generations of molecular biologists’ studying the effects of apparent biological traits genes exert on utilizing technologies like gene knockout have made breakthroughs in many crucial aspects. On the macro level, statistics and other data analysis techniques are introduced to study the relationship between gene sequences and biological phenotype. The accumulation of basic scientific research gradually brings breakthroughs in clinical applications.

There are now two types of clinical applications mainly, one aims at disease screening of ordinary people. It infers people’s future risks of getting cancer by measuring the known genes associated with a disease loci. The other aims at the diagnosis cancer and other deadly diseases. It finds in a series of drugs or plans the most effective one for certain patients by testing the loci of certain genes.

Data from BBC research shows that total global gene sequencing market increased from $ 7.941million in 2007 to $ 4.5 billion in 2013, and will reach $ 11.7 billion in the year of 2018 with the CAGR up to 21.2%.

Currently, the market of de novo sequence platform is mainly taken by several major manufacturers, including the Illumina, Ion Torrent / Life Technologies (was the acquisition of Thermo Fisher in 2014), 454 Life Sciences / Roche, etc.

Under such a circumstance, the next generation sequencing technology (second-generation sequencing) appears. As an emerging industry, the next-generation sequencing technology can be applied in clinical testing like antibody discovery, health industry, industrial and agricultural use of gene-oriented study as well as scientific research and development.

Struggling With Antibiotic Resistance

I never saw it coming. The process started with a small, but painful sensation right in the middle of my right butt-cheek. A very annoying problem because I am a writer squirming around as I try to fill up empty screens with words.

At first, I downplayed it as just some stupid little irritation that would go away as soon as it came. Being a diabetic for about 25 years now I am prone to inflammations and infections. This was just another in a long succession of intermittent, annoying, health problems.

At the onset, the thought never occurred that it might be an infection. I had not had any accident, no cuts, abrasions or scrapes so that did not pop up as the culprit. That is until it persisted and grew into an open sore. The pain level also rose dramatically.

I went to the doctor. He did not think it was serious. He wrote a prescription for a mild antibiotic and a cream. I left the office confident that the problem was in hand. Back home I took a pill, applied the cream and applied a bandage.

By that point sitting at my computer and performing my daily writing ritual was growing into a serious challenge. The pain was so intense that I had to force myself not to move at all. That worked for a while. I took the full antibiotic course and got into the habit of cleaning and dressing the open wound three times a day.

The process began last November. As I came to the end of the bottle of pills I was hit by a wave of disappointment and confusion. I had to face the fact that the infection had gotten worse, not better. Had the doctor misdiagnosed it? Had he given me the wrong antibiotic? Worse, did I have some rare new infection?

I went back to his office in a far more worried state than I was during my first visit. He admitted he was puzzled but brushed that aside. I got a new prescription for a stronger antibiotic that was going to require four consecutive injections.

Once again I returned home feeling a bit numb but optimistic that this stronger injectible antibiotic would do the trick. I got the injections and waited for the medication to build up in my system and wipe out the infection. I waited and waited. The situation did not get better it got even worse.

By then I could not sit and also had a hard time walking. The pain was constant even when I was trying to write while lying down. This time when I returned to the doctor’s office he told me to go to the emergency room. He would not try another antibiotic. In fact, he seemed at a loss.

Instead, I went to a clinic. The doctor there did prescribe another antibiotic, took a culture for the lab and had nurses scrub the wound. It just kept growing as if the antibiotic cream was a placebo and the injections had been nothing but water.

At that point, I had added symptoms including chronic fatigue and the first signs of depression. These two are features of a diabetic’s life and I knew what they were as soon as they arose. My immune system was beaten down and using whatever energy it could get from whatever source was available.

I did not get my hopes up during the third two-week course of the latest antibiotic. In fact, I was on pins and needles the whole time. When I finished I was not surprised that it too had failed at its job. Still, it never occurred to me that I might be antibiotic resistant.

By that point, I began to consider the possibility that my 71-year old body was running out of gas. My energy level was so low, and pain level so high that I could not write. I could only walk the short distance to the corner store to ship and my mood was buried in the pits.

When I returned to the doctor’s office he did not seem too surprised by the fact his prescription had failed. He put the lab report up on the lightbox and pointed to it. “I am afraid the results show you are resistant to every type of antibiotic we have.”

I simply could not wrap my mind around his statement. I had never thought that I had overused antibiotics to the point my immune system built up a total tolerance. Then again, nobody ever tells you where that line is.

In fact, I had taken at least one course each of the 3 previous years to cure sinus infections. I left the office completely confused and with no idea of what to do next. The doctor suggested that I schedule an operation to remove the infected area. My thought was that hospitals are great places to contract infections. I was not eager to take that option especially when it would mean I could not sit at the computer and work for a much longer period of time.

Believe it or not, that whole process went on for four months and I still had the infection. I decided to tough it out and see if my body would mobilize and get rid of it. Then I had an impulse to try one more doctor, a female who I had seen before and was impressed by.

She gave me a spray that the other doctors never mentioned, Microdacyn. This spray is a biologically active treatment for the treatment of acute and chronic wounds that are difficult to heal. I applied and applied it every day and started seeing improvement much to my relief.

My status now is guarded and uncertain. I do now I cannot afford one more sinus infection. I did discover one effective treatment, Phage Therapy. However, that is only available in Eastern Europe. I advise a very conservative approach when it comes to taking antibiotics, only do so when it is truly necessary.
