The present results do not show any effect of gastric reduction surgery on postoperative esophageal function or gastroesophageal reflux symptoms.

pN2 patients with mediastinal lymph node skip metastasis have a more favorable prognosis compared to pN2 patients with continuous infiltration of the regional lymph nodes. Patients with a continuous lymph node involvement show an increased number of infiltrated mediastinal lymph nodes per patient compared to patients with a non-continuous spread. Skip metastasis is an independent prognostic factor of survival. The presence of skip metastasis seems to be a unique subgroup of pN2 disease in NSCLC.

Expression of MMP-2 is strongly associated with tumour progression and lymph node metastasis in gastric cancer. Therefore MMP-2 staining may be clinically useful as predictor of tumour progression, especially for lymph node metastasis.

Clinical "reality" reflects the controversies of "scientific evidence" for FSFT after multiple trauma in Germany. Although decision making is currently based on unvalidated criteria, anatomic and physiologic injury severity appears to influence the choice of management concept.
