Modern treatments for colorectal cancer in 2025: what does the future hold?

A vastagbélrák diagnózisa ijesztő lehet, de fontos tudni, hogy az orvostudomány folyamatosan fejlődik. A modern kezelések egyre hatékonyabbak és kíméletesebbek, ami jobb esélyeket és magasabb életminőséget biztosít a betegek számára. Az Endomedix Gastroenterology Centre elkötelezett amellett, hogy a legkorszerűbb diagnosztikai és terápiás eljárásokat tegye elérhetővé. Cikkünkben bemutatjuk, milyen újdonságok várhatók a vastagbélrák kezelésében 2025-ben és azon túl.

Colorectal cancer: an increasingly treatable disease

Colorectal cancer, or colorectal carcinoma (CRC), is a malignant tumour of the inner surface of the colon or rectum. It is one of the most common cancers in Hungary and worldwide. The disease usually develops slowly from benign polyps, so early detection is key to successful treatment.

A vastagbélrák előfordulása 50 éves kor felett jelentősen megnő, de az utóbbi években egyre több fiatalabb beteget is diagnosztizálnak. A jó hír az, hogy a szűrővizsgálatok, mint például a vastagbéltükrözés (kolonoszkópia), képesek időben felfedezni az elváltozásokat, sokszor még a rákos átalakulás előtt. Az időben eltávolított polipokkal a betegség megelőzhető. Az Endomedix Gastroenterology Centre szakemberei kiemelt figyelmet fordítanak a szűrésre és a korai diagnózisra.

Modern tools for diagnosis

An accurate diagnosis is the basis for effective treatment. As medical science advances, diagnostic procedures are becoming more precise and less burdensome.

Endoscopic examinations

with kolonoszkópia (vastagbéltükrözés) továbbra is az arany standard a vastagbélrák diagnosztizálásában. A vizsgálat során egy vékony, hajlékony eszközzel, az endoszkóppal tekintik át a teljes vastagbelet. Ez nemcsak a daganatok felismerését teszi lehetővé, hanem a rákmegelőző állapotnak tekinthető polipok azonnali eltávolítását is.

The evolution of modern endoscopy:

• Virtual chromoendoscopy (NBI, LCI, BLI): These special light imaging technologies highlight the smallest changes in the mucosa and the structure of blood vessels. They help doctors spot suspicious areas more easily, even flat, hard-to-see polyps.
• High resolution endoscopes: HD and 4K resolution devices provide a detailed image, which increases the accuracy of diagnosis.
• Confocal laser endomicroscopy: This cutting-edge technology allows real-time examination of cells at thousands of times magnification during the procedure, which can help to immediately identify the type of tumour.

Imaging techniques

If the colonoscopy confirms a tumour, further imaging tests are needed to determine the extent (stage) of the disease.

• CT and MRI: A computed tomography (CT) scan and magnetic resonance imaging (MRI) give a detailed picture of the abdomen and chest, so that any metastases in the lymph nodes, liver or lungs can be detected. In the case of rectal cancer, MRI is particularly important to accurately assess the relationship between the tumour and the surrounding tissue.
• PET-CT: Positron emission tomography (PET-CT) helps to identify active cancer cells in the body, giving a more accurate picture of the extent of distant metastases.

Biomarker studies

Molecular genetic testing of tissue samples (biopsies) taken from tumours is now essential. These so-called biomarker tests reveal the unique genetic characteristics of the tumour (e.g. KRAS, NRAS, BRAF mutations, MSI status), which determine which targeted therapy or immunotherapy may be most effective for the patient.

Modern directions for colorectal cancer treatment in 2025

The treatment strategy is always personalised, depending on the stage of the tumour, its location, the general condition of the patient and the molecular characteristics of the tumour.

1. Minimally invasive endoscopic procedures

Superficial tumours and larger polyps detected at an early stage can now often be removed endoscopically without surgery. These procedures are much gentler than conventional surgery.

• Endoscopic submucosal dissection (ESD): With this advanced technique, even larger, flat tumours can be removed from deeper layers of the intestinal wall in one piece, without opening the intestinal wall.
• Endoscopic full thickness resection (EFTR): It can be used in special cases where the tumour has spread deeper or is in a scarred area. During the procedure, the full thickness of the intestinal wall is removed through the endoscope.

2. Surgical treatment: laparoscopy and robotic surgery

If the tumour has spread deeper, surgical removal is necessary. Modern surgery is also moving towards minimally invasive procedures.

• Laparoscopic surgery: The abdominal surgery is performed through small incisions using a camera. The advantages are less surgical strain, faster recovery, less pain and a better aesthetic result.
• Robotic surgery: From a console, the surgeon controls a robot that moves the surgical instruments. The robotic arms allow more precise movement, which is particularly useful for rectal tumours in narrow pelvises.

3. Drug treatments: targeted therapy and immunotherapy

Modern drug therapies have revolutionised the treatment of advanced or metastatic colorectal cancer.

• Targeted therapy: These drugs do not kill rapidly dividing cells in general (like chemotherapy), but specifically inhibit the molecular pathways responsible for the growth and spread of tumour cells. Biomarker studies are used to decide which targeted therapies (e.g. EGFR inhibitors, VEGF inhibitors) are effective in which patients.
• Immunotherapy: Immunotherapy drugs activate the immune system's own cells to recognise and destroy tumour cells. They can be particularly effective in a specific subset of colorectal cancers called microsatellite instability (MSI-H). Research is ongoing to make immunotherapy available to other patient groups.

4. Radiotherapy

Radiotherapy is mainly used in the treatment of colorectal cancer, usually in combination with chemotherapy, before surgery (neoadjuvant treatment). It aims to reduce the size of the tumour, which increases the chance of complete surgical removal and reduces the risk of recurrence. Modern techniques (such as IMRT) allow more precise targeting of radiation, sparing the surrounding healthy tissue.

What does the future hold? New research directions

Colorectal cancer research is a very active field. Some promising directions that could shape treatment practice in the coming years:

• Liquid biopsy: A simple blood test can detect DNA fragments from the tumour. This technology could revolutionise screening, monitoring response to treatment and early detection of recurrence.
• Microbiome research: There is growing evidence that the composition of gut bacteria influences the development of colorectal cancer and the effectiveness of treatments. In the future, targeted modification of the microbiome may also become part of therapy.
• Even more personalised therapies: The development of mRNA-based vaccines and CAR-T cell therapies may also open up new possibilities for the treatment of colorectal cancer.

Your role in recovery

Although modern medicine has impressive tools, the active involvement of the patient is essential.

• Take part in screening tests: Over the age of 50, or earlier if there is a family history, regularly attend the recommended screenings. Colonoscopy can now be performed under general anaesthesia, making it completely painless.
• Do not ignore the symptoms: Persistent diarrhoea or constipation, bloody stools, abdominal pain or weight loss of unclear origin are all signs that you should seek medical advice.
• Feel free to ask: Dare to ask your doctor during diagnosis and treatment. It is important that you understand your options and are a partner in the decision-making process.
