Sentence examples for regional control rate from inspiring English sources

The rationale for observation and salvage neck dissection is the concern of overtreatment because additional surgery for all patients is unlikely to increase regional control rate [ 5].

Cooper et al. [8] have also reported that postoperative radiotherapy and chemotherapy can improve disease-free survival and improve local and regional control rate in patients with head and neck squamous cell carcinoma.

In a recently reported study by Lin et al, exclusion of level Ib lymph nodes and supraclavicular region for elective treatment in IMRT for locoregionally advanced NPC did not reduce the probability of regional control rate as compared to historic controls [ 33].

Their regional failure rate was generally below 10%, similar to regional control rates in planned neck dissection series [ 5].

The 3-year overall survival rate of 89% without concurrent chemotherapy in the current series further suggested that improved local and regional control rates could result in an improved overall survival.

Although direct comparison of results from different clinical trials is not feasible, substantial improvement from the superb local and regional control rates of >95% may require a paradigm shift in the current chemotherapy strategy.

Available data suggest that lymphadenectomy performed for clinically evident nodal disease is associated with more complications and poorer regional control rates than when the same procedure is done for microscopic disease.

No significant improvement in local and/or regional control rates as well as 3-year MFS, DFS or OS could be detected between patients received IMRT with or without concurrent chemotherapy (Tables 3 and 4).

A validation of the sentinel lymph-node method mandates that patients with a mere biopsy of the sentinel nodes should have equal regional control rates as patients after elective neck dissection.

However, since the 3-year local and regional control rates equaled 95%and97%7%, respectively for patients treated without concurrent chemotherapy, detecting significant improvement with a magnitude of 1%-21%-2%m superbuperb outcome is unlikely even with a substantial number of patients in both arms.

However, since a true biopsy of the sentinel node is not yet established for head and neck cancer, we formulated as a prerequisite that patients with a mere biopsy of the sentinel nodes should have equal regional control rates as patients after elective therapy of the neck.
