PURPOSE

Tumor cell dissociation—the histologic finding of small solid carcinoma cell clusters and groups of dissociated dedifferentiated carcinoma cells at the invasive front–is related to tumor metastasis and patient prognosis. However, few previous reports have examined tumor cell dissociation in submucosal invasive colorectal carcinoma. We investigated the relation between tumor cell dissociation and lymph node metastasis in submucosal invasive colorectal carcinoma. We also examined immunohistochemical expression of E-cadherin and beta-catenin in submucosal invasive colorectal carcinoma.

METHODS

Submucosal invasive colorectal carcinoma tissue samples from 20 patients with lymph node metastasis and 100 patients without lymph node metastasis were evaluated. Sections stained with hematoxylin and eosin were evaluated for tumor cell dissociation. Immunohistochemistry was used to determine the expression and cellular distribution of E-cadherin and beta-catenin.

RESULTS

Tumor cell dissociation was more frequently identified in submucosal invasive colorectal carcinoma cases with lymph node metastasis than in those without lymph node metastasis (P = 0.0001). Decreased membranous expression of E-cadherin occurred more frequently in submucosal invasive colorectal carcinoma cases with lymph node metastasis than in those without lymph node metastasis (P = 0.025). Nuclear expression of beta-catenin tended to be present in submucosal invasive colorectal carcinoma cases with lymph node metastasis (P = 0.063). Decreased membranous expression of E-cadherin occurred more frequently in submucosal invasive colorectal carcinoma cases with tumor cell dissociation than in those without tumor cell dissociation (P = 0.0023).

CONCLUSIONS

Our results suggest that there is a relation between tumor cell dissociation and lymph node metastasis in submucosal invasive colorectal carcinoma. Tumor cell dissociation formation might be related to abnormal expression patterns of E-cadherin and beta-catenin in submucosal invasive colorectal carcinoma. Tumor cell dissociation and decreased membranous expression of E-cadherin would be important predictive markers for lymph node metastasis in submucosal invasive colorectal carcinoma.

Darüber reden und aus Fehlern lernen, sollte das Motto in der Medizin lauten. Und zwar nicht nur im Sinne der Patientensicherheit. Eine negative Fehlerkultur kann auch die Behandelnden ernsthaft krank machen, warnt Prof. Dr. Reinhard Strametz. Ein Plädoyer und ein Leitfaden für den offenen Umgang mit kritischen Ereignissen in Medizin und Pflege.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
