Breast cancer. Vitamin D from A New Hope
A study by the University of Toronto Candies presented at the congress of the Society ‘U.S. Oncology (ASCO) show the effectiveness of vitamin D in fighting breast cancer and improved survival of patients. Researchers have found it a very high probability of developing metastases (94%) and go to their death (73%) in women with breast cancer at diagnosis showed that a vitamin D deficiency.
The analyzed sample consists of 512 patients who had received diagnoses between 1989 and 1995, all were followed until 2006. Within ten years 83% of women who showed good levels of vitamin D in the blood did not develop metastases and 85% had survived.
However, scientists warn, further investigations are needed before recommending to women with breast cancer, vitamin D supplementation in the diet. In fact, despite its deficiency is quite common in this type of disease , the researchers , by their own admission, have not been able to establish whether this is a coincidence.
Also at the congress of ‘Asco were presented with two Italian studies, coordinated by the University’ of Modena and Reggio Emilia, who have shown the effectiveness of a molecule (known as lapatinib) can reduce the tumor mass and avoid the use of excision breast surgery (mastectomy). The molecule lapatinib, used in therapy before surgery, has allowed conservative surgery in 50% of cases. The sample in this case consisted of a hundred women.
Moreover, as explained by Pier Franco Conte, director of the department of oncology and hematology at the University of Modena and Reggio Emilia, in 45% of patients, therapy and surgery have led to the disappearance of cancer. However, scholars point out of the U.S. Congress, there is a growing tendency to resort to mastectomy instead of breast-conserving surgery.
