What is meant by \u2018surgical margin\u2019?<\/strong><\/h2>\n

During cancer surgery, the aim is not only to remove the visible tumour, but also a strip of healthy tissue surrounding it.<\/p>\n

This ring of tissue is known as the surgical margin<\/em>. From a pathological point of view, this tissue is analysed in the laboratory to check for residual tumour cells.<\/p>\n

 <\/p>\n

What does it mean when they are \u2018free\u2019?<\/strong><\/h2>\n

When the margins are free, it means that no cancer cells have been found when the edge of the removed tissue is analysed. This indicates that the resection has been complete. Conversely:<\/p>\n

    \n
  • Positive or compromised margin: tumour cells are detected at the edge, suggesting that part of the tumour may have been left inside the body.<\/li>\n<\/ul>\n
      \n
    • Close margin: the cells are very close to the edge but do not touch it; this can also lead to clinical uncertainty.<\/li>\n<\/ul>\n

       <\/p>\n

      Why is it important to have clear surgical margins?<\/strong><\/h2>\n

      Relationship with local tumour control<\/strong><\/h3>\n

      Having negative or clear margins reduces the likelihood of the tumour reappearing in the same area (local recurrence). In many types of cancer, this is directly associated with improved survival rates and disease control.<\/p>\n

      Role of the pathology report<\/strong><\/h3>\n

      The margins are analysed after the operation in a pathology report. This document is essential to confirm that the surgery has achieved its oncological goal and usually defines the next steps in the treatment.<\/p>\n

       <\/p>\n

      What happens if the margins are not clear?<\/strong><\/h2>\n

      Positive or compromised margins<\/strong><\/h3>\n

      When surgical margins are positive, it means that cancer cells remain in the body, which increases the risk of recurrence. In these cases, the medical team may recommend:<\/p>\n

        \n
      • Another surgery to enlarge the resection.<\/li>\n<\/ul>\n
          \n
        • Additional treatments to remove the remaining cells.<\/li>\n<\/ul>\n

           <\/p>\n

          Implications for treatment<\/strong><\/h3>\n

          Depending on the type of tumour, its location and the patient’s general condition, other strategies may be used, such as:<\/p>\n

            \n
          • Radiotherapy<\/li>\n<\/ul>\n
              \n
            • SBRT<\/li>\n<\/ul>\n
                \n
              • Chemotherapy<\/li>\n<\/ul>\n
                  \n
                • Targeted therapies or immunotherapy<\/li>\n<\/ul>\n
                    \n
                  • Percutaneous ablation<\/li>\n<\/ul>\n

                    These decisions are made on an individual basis and agreed upon by the multidisciplinary team.<\/p>\n

                     <\/p>\n

                    Factors influencing the achievement of clear surgical margins<\/strong><\/h2>\n

                    Tumour location and type<\/strong><\/h3>\n

                    Some tumours are more difficult to remove completely due to their size, shape or proximity to vital structures. For example, tumours in the rectum, pancreas, liver metastases close to arteries and veins in the liver, and tumours in the cervicofacial region present specific surgical challenges.<\/p>\n

                    Gastric tumours with signet ring cells require wider margins than other types of tumours due to their aggressiveness and pattern of spread.<\/p>\n

                    Sarcomas require en bloc resection with adequate surgical margins.<\/p>\n

                    Surgical team experience<\/strong><\/h3>\n

                    A highly specialised surgical team, such as the one at IVOQA, is key to achieving clear margins in complex tumours. Experience, training and the use of advanced technology make all the difference.<\/p>\n

                     <\/p>\n

                    What role does IVOQA play in precision cancer surgery?<\/strong><\/h2>\n

                    Technology and a multidisciplinary approach<\/strong><\/h3>\n

                    At IVOQA, we use cutting-edge surgical techniques such as minimally invasive surgery, advanced laparoscopy and robotic surgery, as well as 3D modelling for surgical planning.<\/p>\n

                    These are combined with the joint work of surgical oncologists, medical oncologists, radiologists and pathologists for a comprehensive assessment.<\/p>\n

                    Some advanced techniques such as IRE (irreversible electroporation) are revolutionising the treatment of pancreatic cancer with vascular involvement, enabling a greater number of patients with unresectable pancreatic cancer to undergo surgery.<\/p>\n

                    Commitment to patient oncological safety<\/strong><\/h3>\n

                    Our goal is to ensure that every patient receives the best possible surgical option, with clear margins as a standard of quality. IVOQA is a national leader in highly complex surgery, including advanced or metastatic cancers.<\/p>\n

                     <\/p>\n

                    Having clear surgical margins means that the tumour has been completely removed, leaving no malignant cells in the body. This result is a fundamental pillar for improving prognosis and reducing the risk of recurrence.<\/p>\n

                    At IVOQA, we work with a precision and personalised surgical approach, tailored to each type of tumour and patient. If you are undergoing treatment or seeking a second opinion, we invite you to consult us for a comprehensive and rigorous evaluation. We are here to help you with commitment, science and experience.<\/p>\n

                    Frequently asked questions about clear surgical margins<\/h2>\n
                    \n
                    What does it mean when surgical margins are \u2018clear\u2019?<\/div>\n
                    It means that no tumour cells were found at the edges of the tissue that was removed during surgery. This is an indication that the entire tumour was successfully removed and that there are no visible traces of cancer in the area that was operated on.<\/div>\n<\/div>\n
                    \n
                    How is it determined whether the margins are clear?<\/div>\n
                    After surgery, the removed tissue is analysed in the pathology laboratory. The pathologist examines the edges of the tissue under a microscope to check whether they contain cancer cells.<\/div>\n<\/div>\n
                    \n
                    What happens if the surgical margins are not clear?<\/div>\n
                    When tumour cells are detected at the margins (also called positive or compromised margins), a second surgery may be necessary or the treatment may need to be supplemented with radiotherapy or chemotherapy, depending on the type and location of the tumour.<\/div>\n<\/div>\n
                    \n
                    Can clear margins be obtained in all types of cancer?<\/div>\n
                    This is not always possible, as it depends on factors such as the type of tumour, its size, its location and its relationship with neighbouring organs. In some cases, obtaining completely clear margins can be a technical or anatomical challenge and may require chemotherapy or radiotherapy before surgery to increase the chances of success.<\/div>\n<\/div>\n
                    \n
                    Do clear surgical margins guarantee that the cancer will not return?<\/div>\n
                    Clear margins significantly reduce the risk of local recurrence, but they do not guarantee 100% that the cancer will not return, as the cancer may have spread through nearby lymph nodes, vessels and nerves. Therefore, follow-up medical care and, in some cases, additional treatments are important.<\/div>\n<\/div>\n
                    \n
                    What advantage does a specialised centre such as IVOQA offer in this type of surgery?<\/div>\n
                    At IVOQA, we use high-precision surgical techniques and a multidisciplinary approach that improves the likelihood of achieving clear surgical margins. This translates into safer surgery and better oncological outcomes for the patient.<\/div>\n<\/div>\n<\/div>\n
