How Is a Personalised Oncology Treatment Plan Determined?

September 17, 2026 | 4 min read

One of the most determining factors in the success of cancer treatment is the development of a therapeutic plan tailored to each patient. Cancer is not a single, uniform disease; even cancers affecting the same organ can display very different biological behaviours. This is why the implementation of a personalised treatment is based not only on the type of cancer but also on its progression, its stage, and the individual characteristics of the patient. Modern oncology relies on a multidisciplinary approach in which oncologists, surgeons, radiologists, and pathologists work closely together to analyse all of the patient's data and to define the most appropriate therapeutic strategy.

Within this process, the aim is not solely to treat the current disease but also to anticipate the patient's response to the various therapeutic options. Quality of life, treatment tolerance, and long-term outcomes are all carefully taken into account. Depending on the case, surgery may be preferred, whilst for other patients, chemotherapy, immunotherapy, or targeted therapies may be more suitable. This personalised approach helps to avoid unnecessary treatments and to focus on the most effective solutions, thereby ensuring a more controlled and more relevant course of care.

How Does the Stage of Cancer Influence the Choice of Treatment?

The stage of cancer is one of the essential pillars in defining treatment, as it indicates the extent of the disease within the body. At early stages, the tumour is generally localised, which often allows surgical management with a high chance of complete cure. In these situations, treatment is usually shorter and success rates are higher. At advanced stages, by contrast, the cancer may have spread to the surrounding tissues or to distant organs, requiring a more complex and combined therapeutic approach.

The stage does not determine only the type of treatment but also the order in which it is applied. For example, in certain cases, chemotherapy is administered first in order to reduce the size of the tumour before surgery. In other situations, surgery is carried out as a priority. Radiotherapy may also be incorporated depending on the degree of spread. Precise staging is therefore essential for ensuring a relevant therapeutic choice and for optimising the chances of successful treatment.

How Do the Tumour Type and Genetic Characteristics Influence the Decision?

Today, cancer treatment is no longer limited to the organ affected — the molecular characteristics of the tumour play a determining role. Cancers that appear similar may belong to different genetic subgroups, which directly influences their response to treatment. This is why genetic tests and biomarker analysis have become indispensable tools in therapeutic planning. Targeted therapies and immunotherapy, in particular, are tailored according to the genetic profile of the tumour.

Molecular profiling makes it possible to identify the most effective treatments for each patient. For example, certain genetic mutations make targeted therapies more appropriate than conventional chemotherapy. This approach not only improves the effectiveness of treatment but also reduces unnecessary side effects. Furthermore, genetic characteristics provide valuable indications regarding the likely course of the disease and the risk of recurrence. Treatment is therefore designed not only for the current situation but also with a long-term preventive perspective.

How Important Is the Patient's General Condition in the Planning?

In oncological care, the patient's overall health is a key element. Every treatment places a certain degree of strain on the body, and it is essential that the patient is able to tolerate it. Age, the presence of chronic conditions, the state of the immune system, and general physical condition all strongly influence the therapeutic choice. In older patients or those with comorbidities, gentler and better-tolerated treatments may be preferred.

The patient's ability to maintain their daily activities is also taken into consideration. Certain treatments can cause significant side effects, which makes them unsuitable for some profiles. The aim is not only to control the disease but also to preserve the patient's quality of life as far as possible. Through a personalised approach, adherence to the treatment is improved and the therapeutic benefits are optimised. This comprehensive vision represents one of the essential foundations of modern oncology today.
