The phrase "number of recurrence" is correct and can be used in written English.
You can use it to refer to the frequency or amount of something that is repeated in a certain period of time. For example, you could say "We measured the number of recurrence of influenza outbreaks over the last 10 years."
The number of recurrence and the median recurrence time were 64 cases and 522 days in IHCCs, and 78 cases and 960 days in EHCCs, respectively.
One possible reason for positive result in recurrence could possibly be due to false positives based on a relatively small number of recurrence cases (less than 10%).
The number of recurrence tumors that were PEDF-negative was statistically significantly different from the number of primary tumors that were PEDF-negative (P < 0.000001) (Table 1).
We found that ~83.3% of endocrine-responsive tumors were PEDF-positive and 16.7% were PEDF-negative, which was significantly different from the number of recurrence tumors that were PEDF-negative (P < 0.000001) or PEDF-positive (P < 0.00008) (Table 1).
Because stage 1 tumors are associated to a very limited number of recurrence and stage 4 to negative outcome we focalized our analysis on the 72 stage 2 and 3 CRCs present in our dataset (17.5% stage 2 and 40.5% stage 3 CRC patients will eventually show disease progression at 5 years) [ 14] (see Additional file 7).
The high number of recurrence in our study and the time between episodes suggest reinfection playing most of the cases as it is expected in a high burden area [ 1, 4, 7, 9], with a high strain diversity circulating [ 14– 16].
Because of the small number of recurrences an additional group of 15 similarly treated women with recurrent breast cancer was also studied.
Data with respect to the patients' ages, sex, tumor locations, and surgical treatment history, as well as the radiographic findings and number of recurrences, were analyzed.
Meary et al. in their nineteen cases of desmoid fibroma of the limbs noticed a large number of recurrences after surgical excision [39].
More importantly, the number of recurrences was found to be much lesser in such patients, and systemic ganciclovir therapy could be discontinued after resolution of lesions.
There where twice the number of recurrences in the robotic group, and the follow-up was shorter in the robotic group (Table. 2).
