Women with bladder or kidney cancer may lose a timely diagnosis if they are already being treated regularly for recurrent UTIs, according to a new study presented at the Cancer Research UK Early Diagnostic Conference in Birmingham today.
Studies have shown that this may be due to the fact that a person who is prone to infection is more likely to suffer from another IPT than from a prospective cancer study.
An analysis of 24 studies and more than 100,000 people found that up to two-thirds of blood in urine – a symptom of IMP and a possible sign of cancer – had not been screened within six months of their initial visit to a doctor.
UTIs are more common in women than in men. Although IPA is not directly related to cancer, the lack of recurrent infections or blood in urine, checked by a doctor, may lead to a delayed diagnosis of cancer, especially among older women.
Researchers believe that developing electronic tools within GP's existing computer systems to help patients with persistent symptoms or recurrent IPP in older people can help GPs to determine who may need further research or to turn to a urologist.
Dr. Yin Zhou, lead author at Cambridge University, said: "The discovery of cancer is vital to providing the best treatment options and improving survival. This study is an important step in improving our understanding of why some people are diagnosed later than others.
"Although IPP is the second most common condition that doctors prescribe antibiotics for some people, the symptoms of IPT may be masked symptoms of bladder or kidney cancer. Only a small number of patients with persistent symptoms and recurrent IPP develop cancer, but it is important not to miss them. The next step would be to find a way to find these patients earlier.
More than 10,500 people have been diagnosed with kidney cancer and about 8,500 people have been diagnosed with bladder cancer every year in England. Of these, about 3400 were diagnosed with late-stage renal cancer and 1,800 with bladder cancer at a later stage.
When caught at an early stage I, the five-year survival rate of patients with kidney cancer was seven times greater than in the IV stage diagnosis. And more than twice as many patients experience bladder cancer for at least one year when diagnosed with stage I disease compared to stage IV.
Sara Hyom, director of early diagnosis at Cancer Research UK, said: "Early stages of cancer do not always show obvious symptoms, but this study highlights the importance of tracking persistent symptoms and providing permanent, overlooked problems. ways to support GPs and practices to ensure that all patients get an accurate diagnosis as quickly as possible – this can make everything different in their experience and outcome.
Dr. Richard Rope, an expert on cancer in the UK, says: "Doctors see many patients with symptoms suggestive of urinary tract infection, and fortunately most of them will never develop kidney or bladder cancer. we take a step backwards to consider what might be the cause of a repetition of the symptoms rather than assume that the diagnosis is the same as it was before.
"There is no easy way to know which patients should be targeted or seen again. All general practitioners want the best for their patients, so research like this, emphasizing that improvements are needed, such as organizing a review, is very useful."
