Personalized cancer treatment – transfer to individual therapy regimen
In most cases cancer is caused by a mutation of a human genome.
Nowadays, our oncologists use new methods for cancer genomes-oncomarkers (DNA mutations) identification. This allows to identify not only cancer tumor type but also the impact of different drugs that are not included in the standard anticancer therapy. Thus, patient and doctor become to know what exactly will work on a specific tumor of a specific person.
Onсotests are genomic and genetic studies for detection of DNA mutations with using biopsy of tumor tissue or blood test which help to choose correctly the precise cancer treatment (out of standard treatment) for each patient.
Personalized or precision cancer treatment in Israel:
Each person inherits a set of genes from both parents. This gene which is available in almost all cells of the body and embodied in the structure of DNA strands. If in the cellular DNA a defect or mutation occurs, that may cause inclusion of cancer genes. Your body cannot control this process. The defective cell continues to multiply that results in cancer. Mutations can occur as a result of exposure to endogenous and exogenous causes (for example cancerogenic chemicals, radiation, etc.). Only in а very small number of cases the mutation is inherited from parents. In many cases, the cause of the mutation remains unknown.
Why it is important to identifying DNA changes in cancer cells
Detection of DNA mutations in cancer cells and the definition of genes-markers allows to develop personalized treatment – individual therapy protocol in accordance with a genetic profile of cancer tumor. Personalized therapy has an advantage when selecting the most effective treatment, in comparison to standard treatment previously underwent by patient: chemotherapy, radiotherapy and surgery.
Personalized treatment includes special anticancer drugs and cures directed against the mutating cancer cells. Such therapy has much less effect on healthy cells.
In many cases, due to early diagnosis the tumor can be removed by surgery. In some cases, such as colon cancer, breast cancer or prostate cancer, the question often arises whether a preventive treatment, radiotheraphy or chemotherapy is necessary. In such cases, doctor may recommend genetic tests for genes-oncomarkers.
In order to prepare the patient for personalized treatment against a certain type of cancer and tumor mutations tests, three types of researches are applied:
⇒ The study of tissue samples (Tissue Panels) – sequencing genes-oncomarkers method on tissue sample.
⇒The study of sample liquid (Liquid Panels) – sequencing genes-oncomarkers method on blood sample.
⇒ Inclusive genome-proteomic studies (Ultra-Coverage Genomic Proteomic). General genome sequencing of tumor cells on distant tissues.
Differences between chemotherapy, immunotherapy and biological treatment
Nowadays, it is very easy to get lost among the millions of web pages and social networks about cancer treatment (chemotherapy, biological or targeted therapy, immunotherapy (immunological treatment). Before starting treatment it is very important to know the basic concepts, and also to learn how to compare different types of treatment, depending on the type of disease.
Precision treatment of ovarian cancer
Precision (personalized) treatment of ovarian cancer – is the target method that helps to prevent ineffective “trial and error” way, loss of valuable time and to avoid undesirable side effects.
Caris – Molecular test
Caris Molecular Intelligence is an analysis of a cancerous tumor at the molecular level that helps to make the most detailed profile of the malignant tissue, on the basis of which our oncologists can recommend to the patient drugs actually effective on his tumor, and also to determine the list of drugs that will not be effective.
Personalized lung cancer treatment
Lung cancer can origin from different types of lung cells and even within the same cell type, caused by various molecular anomalies. In the personalized treatment of a patient, taking into account his individual circumstances, the first step is to identify the cells of the cancer origin. In 10-15% of cases, lung cancer belongs to the subtype of “small cells”. The majority of people, however, suffer from non-small cell lung cancer (NSCLC). This type of lung cancer is classified as squamous cell carcinoma or adenocarcinoma.
Personalized colon cancer treatment
Colorectal cancer is one of the most common malignant diseases in the world. To date, despite the fact that at the time of detection, about 25% of patients have been diagnosed with multiple spread to other organs (metastases), the survival of 60% of these patients has increased up to 5 years. The range of drugs available…
Personalized breast cancer treatment
The probability of full breast cancer recovery in recent decades has increased significantly, due to the introduction of new scientific developments and research.
Today, in addition to surgery, radiotherapy and systemic treatment according to standard protocols in Israel most of patients receive personalized treatment that really increases the chances of survival and a positive prognosis for each individual patient.
What is personalized cancer treatment
A new approach to cancer treatment is a personalized protocol, tailored individually for each patient.

CANscript is a unique diagnostic
CANscript provides patients and physicians with a reliable prognosis of the response to cancer treatment and also allows to select a personal treatment protocol for each patient, based on the individual characteristics of his body, the tumor and its reactions to certain drugs.
