Multicenter Study
[Complete Mesocolic Excision for Right-Sided Colon Cancer - The Role of Central Lymph Nodes].
Complete mesocolic excision (CME) and central vascular ligation (CVL) for right-sided colon cancer may be superior to standard hemicolectomy in terms of oncological results. This hypothesis is currently being investigated in a large multicentre trial conducted by the authors of this paper (Resektatstudie). Because CVL in right-sided hemicolectomy is technically rather demanding the incidence of central node involvement is of special interest. Therefore, during the single centre pilot phase of our multicentre trial we have analysed the incidence of central lymph node metastasis in CME specimens. ⋯ CME with CVL in right-sided colon adenocarcinoma increases the probability of complete removal of the local lymph node drainage and thus local metastatic lymph nodes. Considering this result an improvement of long-term survival by the CME procedure seems conceivable but needs to be confirmed by the current multicentre trial.

The role of surgical treatment of lung cancer with brain metastases remains controversial. The aim of this study was to determine the long-term outcome and to identify potential prognostic factors in patients with cerebral metastatic non-small cell lung cancer (NSCLC). ⋯ Long-term survival is achievable in highly selected patients with NSCLC and cerebral metastasis by multimodal treatment including resection of the primary lung cancer. Patients with squamous cell carcinoma should be selected carefully for multimodal treatment. Treatment of the brain metastases without whole brain radiation should be avoided.

Survival rates even in advanced tumour stage have been improved for some tumour entities due to progress in adjuvant and neoadjuvant therapeutic strategies. Nevertheless, painful, exulcerated or bleeding wounds can impair quality of life for palliative patients. Increasing evidence in palliative treatment has raised options for plastic-reconstructive surgery to be applied for treatment of local wounds which can improve quality of life for the remaining lifetime for the palliative patients in our institutions. ⋯ Opportunities and limitations in plastic and reconstructive surgery should be continuously presented in tumour boards, to clarify these important procedures for palliative patients to all members of the tumour board. There is an increasing impact of plastic surgery for improving the quality of life in palliative patients in a multimodal therapeutical concept.

Induction chemotherapy followed by surgical resection has been a treatment option for stage IIIA3 N2 non-small cell lung cancer since publication of some small randomised trials during the 1990s. Later on other studies suggested a poor prognosis in cases of persistent N2 disease, so surgical treatment for these patients was not recommended. This study analyses the outcome of patients with persisting N2 disease and tries to identify prognostic parameters within that group of patients. ⋯ The median survival for patients with persisting N2 disease is less favourable compared to patients with mediastinal downstaging. However, the long-term survival for patients with less than 6 involved lymph nodes is 17.5 months. Therefore surgical resection for these patients seems to be justified. After induction therapy a rigorous restaging should be performed to rule out persisting multilevel N2 disease.
