Women who have radiotherapy for breast cancer have a small but significantly increased risk of subsequently developing a primary lung tumour, and now research has shown that this risk increases with the amount of radiation absorbed by the tissue.
A new genetic "signature" to identify prostate cancer patients who are at high risk of their cancer recurring after surgery or radiotherapy has been developed by researchers in Canada.
Two large, landmark radiotherapy studies have shown that it is possible to treat cervical cancer effectively with high doses specifically adapted to each tumor, and with fewer serious side-effects to the surrounding normal organs.
Researchers have shown for the first time that it is possible to reduce the distressing symptoms of dry mouth in patients treated with radiotherapy for head and neck cancers if the radiation dose to a salivary gland (called the submandibular gland) on the opposite side to the tumor is kept to the minimum.
Mathematical prediction models are better than doctors at predicting the outcomes and responses of lung cancer patients to treatment.
Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumor, or a potentially toxic over-dose to the surrounding healthy tissue.
Patients with head and neck cancer and a low haemoglobin (Hb) level do not respond well to radiotherapy and therefore both control of their tumor and disease-free survival are compromised.
New findings from a large Danish database of cancer patients suggest that, even though the human papilloma virus (HPV) can trigger throat cancer, patients who are HPV-positive and are light smokers, or don't smoke at all, have a good response to treatment using radiotherapy alone, without the addition of chemotherapy with its consequent toxic side-effects.
Researchers believe they may have found a way to avoid damaging salivary glands during radiotherapy treatment for head and neck cancer – a discovery that could improve the quality of life of 500,000 patients a year worldwide with the disease.
