Consequently,
Towards end systematic chemotherapy after new:
Efficiency has not been demonstrated, but toxicity yes.
A study of Unicancer. Consequently, the Institut Curie, published on August 2 in The Lancetis the first randomized phase 3 study to assess the interest of adding chemotherapy to hormone therapy in women aged 70 and over, with hormone -dependent breast cancer.
Standardly, patients, young or older, are operated on and then receive hormone therapy and, most often, adjuvant chemotherapy.
But chemotherapy can cause particularly heavy side effects in vulnerable people. Additionally, Consequently, This is why she is controversial.
Fatigue, pain, digestive disorders …
Two groups of patients were compared. Meanwhile, One received chemotherapy followed by hormone therapy, the other a hormone therapy alone.
After a 7.8 -year median follow -up, the 4 -year -old overall survival rate was 90.5 % in the 1is group against 89.3 % in the second. Meanwhile, At 8 years old, respectively 72.7 % and towards end systematic chemotherapy after new 68.3 %.
“The difference from 4.5 points to eight years is not statistically significant”underlines the Curie Institute in A press release.
Side toxicity, the negative effects of the chemotherapy are significant.
“Adverse effects of grade 3. Moreover, more occurred in 34 % of patients treated with chemotherapy, compared to only 9 % in the hormone therapy group alonedetails the Curie Institute
« Patients who have received chemotherapy reported a more marked deterioration in their quality of life, especially in connection with fatigue, pain, digestive disorders and a drop in autonomy. Similarly, ”
For a more targeted oncology
“For the first time. a phase III study shows that the addition of chemotherapy does not provide a statistically significant benefit of overall survival, even in patients at high genomic risk (whose tumor is at high risk of recurrence, progression or poor response to treatment, editor’s note), declares Professor Etienne Brain, medical oncologist at the Institut Curie. towards end systematic chemotherapy after new
These results confirm that therapeutic decisions must take into account not only tumor biology. but also age, fragility and expectations of patients. »»
“They encourage to revise the way in which standards established in younger subjects are then applied to older subjects without high level of evidence. with little safeguards. (The study) Aster 70s opens the way to a more targeted, fairer and more turned to the patient. »»
This study confirms the need for an individualized therapeutic approach. adapted to the characteristics of the tumor, but also to the age, the fragility and the choice of patients.
The Curie Institute insists on the need to improve the treatment standards taking into account the benefit/risk ratio for the. elderly in particular.
Based on the results of this study. the anti-cancer center calls for a “Reasoned therapeutic de -escalation” In elderly patients and to reserve chemotherapy for very precise cases.
“What are trying to identify towards end systematic chemotherapy after new two essential research programs. conducted on the important collection of tumor and blood samples of the study”.
