Salvage Pulmonary Operations Following Stereotactic Body Radiotherapy for Small Primary and Metastatic Lung Tumors: Evaluation of the Operative Procedures.

Stereotactic body radiotherapy is an alternative treatment option for small-sized, primary lung cancers and pulmonary metastatic diseases. In the case of local relapse after stereotactic body radiotherapy, salvage pulmonary resection is considered cautiously. However, no study has described the difficulty of the salvage operations.

[Contribution to survival rate improvement].

For patients with locally advanced HNSCC, where the outcome with conventional radiotherapy is poor, meta-analysis and collective data showed a high level of evidence of loco-regional control improvement by altered fractionated radiotherapy, chemo-radiotherapy with a concomitant approach. For these patients, much evidence indicates overall survival may be improved by concomitant chemo-radiotherapy or hyper-fractionated radiotherapy delivered with increased total dose. There was a significant survival benefit with altered fractionated radiotherapy, corresponding to an absolute benefit of 3.

Patterns of care study of breast-conserving therapy in Japan: comparison of the treatment process between 1995 1997 and 1999 2001 surveys.

Background: The Japan Patterns of Care Study (JPCS) conducted two national surveys to identify changes associated with the treatment process of care for patients undergoing breast-conserving therapy (BCT). Between the two national surveys, the Japanese Breast Cancer Society published its treatment guideline for BCT.

Method: The first survey collected data on 865 patients treated between 1995 and 1997 (JPCS-1), and the second on 746 patients treated between1999 and 2001 (JPCS-2) by extramural audits.
