Examples of these grades were given:Grade 3-pulmonary fibrosis, cirrhosis, CHF, gonadal dysfunction; Grade 4-second malignancy, MI, CVA, organ transplant, paralysis with daily limitations, cognitive dysfunction
In the cancer survivor group, 46% were female, 84% were white, and median age at survey was 27
67% were treated with chemotherapy, and 62% had received radiation
Despite excluding scarring and disfigurement, 77% of the survivors had a chronic condition by the scoring system. 66% had a grade 1 or 2 condition and 38% had a grade 3-5
Grades 1-2 conditions were fairly similar among the survivors and the control group, but the control groups had many less severe conditions
Relative risk of any grade in the survivors was 1.9 and for grade 3-4 conditions, it was 4.2
The relative risk of grade 3-4 conditions in patients receiving radiation was 3.3, and in those receiving chemotherapy, it was 2.9
Factors associated with highest risk included being treated with an anthracycline or alkylator (4.9 RR), chest/abdominal/pelvic radiation (RR6.9), abdominal/pelvic radiation with an alkylator (RR 7.0), chest radiation and and alkylator (RR 7.2)
Even excluding scarring and disfigurement, the vast majority of childhood cancer survivors have at least one chronic condition, with 33% with a grade 3-5 condition
The group of cancer survivors were 4.2 times more likely to have a chronic condition compared to their siblings
Chest radiation and alkylators were associated with the highest risk of chronic disease
Clinical/Scientific Implications This study documents what pediatric oncologists have thought for years-that survivors of childhood cancers have long-reaching implications in the form of chronic problems. This was even more substantiated by comparing the cancer survivors to matched controls in the form of their siblings. This is even without considering scarring and disfigurement, which is extremely common in these patients. Also consistent with common opinion, patients who received both radiation and chemotherapy had a higher incidence of chronic conditions. Though this may simply mean that patients with more advanced disease have higher complications, the effect of treatment cannot be discounted. What may be most interesting about this study is that chemotherapy had just as high of a risk of developing chronic problems than did radiation. Radiation has long been associated with long term problems, yet it seems that chemotherapy is just as toxic, most likely in the form of neuropathies, asthenias, and leukemias. It appears that radiationis not alone in causing cancer survivors long term problems.
Dec 18, 2014 - New research promises to significantly improve the quality of life of colorectal cancer patients, childhood cancer survivors, patients of childbearing age, and those with early-stage breast cancer, according to several studies presented during a June 1 press briefing at the annual meeting of the American Society of Clinical Oncology, held from May 29 to June 2 in Orlando, Fla.
