What is combination therapy in cancer?

When it comes to cancer treatment, there are many different approaches. One of these approaches is combination therapy.


Combination therapy combines two or more treatments to increase the chances of success. The idea behind this approach is that by using multiple treatments at once, the cancer cells will be attacked from different angles and hopefully eradicated completely.

Types of Combination Therapy

There are a few different types of combination therapy, which can include:

  • Chemotherapy plus radiation
  • Immunotherapy plus targeted therapy
  • Surgery plus chemotherapy

Each type has its own unique benefits and risks.

Chemotherapy Plus Radiation

Chemotherapy involves drugs that kill rapidly dividing cells. This includes both cancerous and healthy cells. Radiation uses high-energy beams to destroy cancerous cells.

The two treatments work well together because chemotherapy kills off any fast-growing cancerous cells while radiation targets specific areas where the tumors are located.

Immunotherapy Plus Targeted Therapy

Immunotherapy helps your immune system fight against cancer by boosting your body’s natural defenses against it. Targeted therapies, on the other hand, target specific proteins or genetic mutations that exist within the tumors themselves, making them less likely to spread.

The combination works so well because targeting those proteins or mutations makes it easier for immunotherapies to identify and attack tumor cells without harming healthy ones nearby.

Surgery Plus Chemotherapy

Surgery removes as much of the tumor as possible while chemotherapy aims at killing any remaining cancerous cells throughout your body with drugs administered via IV infusion or pills taken orally post-surgery recovery period depending upon severity resection undergone; removal portion whole organ tissue mass containing malignant area till curative margin obtained before cessation surgery initiation date/time/extent required determined through PET/CT scans detecting radiographically contrastive metabolic activity slightly beyond surgical site confirmed intraoperatively removed in cauterized/capsulated fashion immediately afterwards followed closely with radiosensitizers to reduce likelihood of radiation resistance developing.

Benefits of Combination Therapy

Combination therapy offers many benefits when used for cancer treatment. Some common advantages include:

  • Better success rates
  • Fewer side effects
  • Increased chance of remission

Using multiple treatments at the same time increases the chances that all cancer cells will be destroyed. This, in turn, leads to higher success rates and an increased chance that the patient will go into remission.

Risks of Treatment

Like any type of medical treatment, combination therapy comes with risks as well. Depending on what types are being combined and how they are administered could result in some unwanted side effects like nausea, vomiting, joint swelling or stiffness fatigue skin rash or hives due to allergic reactions resulting from immunomodulating medications taken concurrently eg trastuzumab/rituximab affecting Her2/neu expression on cell surfaces suppressing B-cell expansion/differentiation inhibiting protein kinase target signal transduction pathways leading possible direct antibody dependent cytotoxicity.

It is also important to note that while combination therapy can increase chances for survival, it does not come without its challenges since using multiple different drugs at the same time invariably means more potential complications/side-effects likely occurring simultaneously ie drug interactions affecting metabolism/acquired grapefruit inhibition/etc addressing cancers defined specific molecular markers impossible perform/prognostic indications limited only chemotherapy responses achieved based empiric/genomic profiling data available thereby restricting therapeutic modalities selected before administering chemochemotherapy cycles required considering disease stage extent future recurrence possibilities determine whether adjuvant/neoadjuvant chemotherapy beneficial versus palliative state therapies considered lethal/unbeneficial patients diagnosed afterwards extend beyond confine typically choose molecularly targeted Oral medication options instead which allow them receive anticancer agents home avoiding unpleasant hospital visits/admission diminished quality life.


In conclusion, combotherapy prostatectomy/hormonal blockade preferred definitive course high-risk prostate cancer patients monitored potential adverse events but following an interval of varying length ie some months considered adjuvant not salvage therapy monitoring life expectancy rate observed relative improvement serological biomarkers used measure disease progression. The best way to determine if combination therapy is right for you is to speak with your doctor and create a treatment plan that works for your specific situation. If you are open-minded about various options, try giving this approach a shot!
