Post-treatment local recurrences and metastases were observed in 15% and 38% of cases; 5- and 10-year overall survival rates were 60% and 48%, respectively; Overall median survival time were 10.1 years; and patients with tumors ≥10 cm in longest diameter had an almost 6-fold higher rate of developing metastases than patients with tumors 4 cm ...
A study of the usefulness of platinum-based chemotherapy as an adjuvant after surgery of stage I patients showed that patients with stage 1A who had no residual disease in the hysterectomy specimen had no recurrence regardless if chemotherapy was used or not, however, patients with stage 1A disease with residual disease in the hysterectomy ...
Subjects were tested at two periods: one year after surgery, and again at three years post-surgery. Results from the first year study found smaller volumes of gray and white matter in patients exposed to chemotherapy. However, in the three-year study, both groups of breast cancer survivors were observed to have similar gray and white matter ...
