Development of New Cancer Treatments

Scientists are continually innovating ways to treat cancer more effectively, by creating and testing new drugs. All such substances must undergo an exhaustive clinical trial process before becoming available for patients.

New treatments specifically target cancer cells without harming healthy ones, including immunotherapy drugs that enhance an individual’s immune system’s fight against cancer.


Cancer encompasses an umbrella term for many diseases with various molecular mechanisms, making treatment choices endlessly varied. With that in mind, several new drugs were recently approved that had some connection to cancer; among these were chimeric antigen receptor T cell therapy, an antibody-drug conjugate targeting multiple cancer types, and two PARP inhibitors designed to reduce prostate cancer recurrence risk.

Traditional therapies tend to kill both cancerous and healthy cells simultaneously; newer drugs aim to specifically target cancer cells while sparing healthy ones. A bispecific antibody targeting myeloma cells’ protein called PD-L1 as well as T cells’ immune system-blocking protein called PD-L1 was recently approved; Pembrolizumab (Keytruda) has already revolutionized treatment of various forms of skin cancer as well as breast, lung, endometrial, and kidney cancers by driving them into remission when conventional treatments fail – often times beyond what was anticipated by traditional approaches alone.

As well, other drugs targeting cancer cells include nanoparticles that train immune cells to destroy them and radiation directly targeted toward tumors. Furthermore, research is underway into personalized mRNA cancer vaccines tailored specifically for each individual based on genetic features of their tumor.

Another recent advancement involves liquid biopsies – blood tests designed to identify genes associated with certain cancers – which can identify patients at high risk and help them take steps to lower their cancer risks.

Cancer vaccines, immunotherapy using T cells and molecularly targeted agents that attack DNA-repair enzymes within cancer cells are currently under consideration in clinical trials, while researchers are searching for new techniques to improve screening accuracy, deliver treatment more efficiently and monitor patient response more closely.


Since cancer treatment largely consisted of surgery, chemotherapy and radiation — tools which were effective against malignant cells while also harming healthy ones – there have been an array of new immunotherapie therapies which utilize your own immune system’s power to seek out and destroy tumors – this practice is known as immunotherapy.

Your immune system should recognize and destroy cancerous cells in your body; however, cancer cells may sometimes evade detection or cause your defenses to misfire, making the battle even harder for it. To aid your immune system in finding cancerous cells more quickly and eliminating them effectively, immunotherapy drugs have been developed that “tag” tumors to make them easier for immune recognition as well as strengthening them from within.

Immunotherapy is one of the fastest growing cancer treatments, and Penn faculty are exploring a wide variety of approaches to using it effectively, with encouraging early results. One type of immunotherapy known as adoptive cell transfer involves extracting some immune cells from your blood and then manipulating them in the laboratory in order to increase their ability to seek out and kill cancerous tumors before reincorporating them back into your body where they can find and destroy cancerous tumors.

Other types of immunotherapy involve reconfiguring your natural killer cells (lymphocytes) so they’re more effective at attacking cancerous cells. Chimeric antigen receptor (CAR) T-cell therapy utilizes lymphocytes from your own body and equips them with synthetic receptors specific to each cancer type you have; this enables lymphocytes to target only cancer cells without harming healthy ones.

Immunotherapy utilizing gene editing involves giving immune cells specific molecular signatures for attacking particular types of cancers. Two research teams used CRISPR/Cas9 technology to edit chemotherapy drugs so that they only work against cancerous cells instead of healthy ones.

One promising form of immunotherapy aims to treat mutations that cause cancer by combining it with cancer medicines; recently, for example, one combination using DNA vaccine and targeted therapy that targets KRAS mutations was found to double patients’ chances of being free of their cancer after four years of treatment.


New technologies are helping doctors get inside tumors, providing insights into which genes and proteins fuel their growth. Furthermore, some techniques, known as tumor-agnostic treatments, may even detect cancer that hasn’t spread to other organs yet.

Doctors are using advanced tools to directly combat cancer cells. Cryoablation utilizes ultra-cold temperatures to freeze tumors away, without needing to remove an entire lung; targeted radiation treatments may also be employed against cancerous cells in lungs or prostates.

An exciting area of research involves vaccines that can prevent cancer or reduce its recurrence. Researchers are investigating personalized mRNA cancer vaccines tailored specifically to an individual’s tumor’s unique genetic makeup; these could potentially become available within this decade.

Genetics and computational biology advances are also driving innovative treatments for cancer. Scientists are now working to identify specific combinations of gene alterations that are most likely to lead to certain forms of cancer and then developing models that predict which treatment strategies would work best for each individual based on these predictions. Such tailored approaches could complement existing screening methods for pancreatic and ovarian cancer, or may provide screening solutions when they don’t exist yet, such as pancreatic cancer and its precursors like prostate cancer.

Researchers have also developed tests that can rapidly identify mutations in DNA linked to increased cancer risks. Furthermore, new technologies enable doctors to quickly detect changes in blood when cancer starts growing and spreading.

Other promising advances include immunotherapy drugs designed to strengthen one’s own immune system and nanoprobes – small particles used as treatments against cancer cells – which can be ingested, injected or tattooed onto skin and target cancer proteins that cannot be effectively tackled using existing drugs.


Surgery has long been the go-to treatment for cancer, consisting of the removal of both tumor and nearby healthy tissue. Surgeons who specialize in performing these operations are known as surgical oncologists.

Scientists are continually creating innovative tools to detect and treat various forms of cancer. The most recent techniques provide better outcomes with reduced side effects.

Targeted therapy works to stop the growth and spread of specific cancer cells without harming healthy ones, while ablation therapy uses heat or cold to destroy tumors minimally invasively, offering another promising minimally invasive alternative to surgery. Furthermore, natural antioxidants have shown promise as ways to track free radicals responsible for cell damage while potentially stopping or slowing cancer from progressing further.

Other advances in cancer treatments include the combination of chemotherapy and immunotherapy drugs that work to stimulate the immune system to attack cancer cells. By combining these approaches, survival rates improve significantly while patients can tolerate higher doses of chemotherapy treatment more easily.

One of the most exciting advances in cancer treatment involves developing more accurate methods for targeting cancer cells with radiation and drugs. New technologies allow physicians to more precisely pinpoint tumors and provide more powerful therapies like chemotherapy or immunotherapy treatments.

One such advance is a new type of radiation machine which allows doctors to deliver more targeted therapies and limit exposure times to radiation. With this technology, doctors can customize treatments specifically to each tumor shape for maximum efficacy and reduce exposure times accordingly.

Researchers are also making strides toward making the delivery of cancer drugs more efficient. For instance, they are creating ways to administer multiple medicines simultaneously or sequentially that maximize efficiency and effectiveness – techniques which could substantially decrease how often chemotherapy must be given as well as the associated costs.

Cancer treatments of the future promise an improved quality of life for more individuals living with this deadly illness, but a cure still eludes many individuals battling this fatal illness. Researchers continue to conduct studies in search of one, while new cancer therapies have been made more available by hardworking scientists who dedicate themselves to finding answers to cancer’s riddle.
