Abstract

Purpose

This study examined the correlation between depth of local invasion in colon cancer and tumor spread and patient survival.

Methods

A cohort of 796 patients with a complete set of TNM staging information following an elective resection for colon cancer was selected. The rates of lymph node and distant metastasis, tumor differentiation, and extramural venous invasion for different tumor (T) categories were compared. The effects of initial tumor (T) category on overall patient survival were studied.

Results

The depth of local tumor invasion correlated strongly with nodal involvement (P = 0.0001), rates of extramural venous invasion (P = 0.0002), poor differentiation (P = 0.0001), and distant metastasis (P = 0.0001). Fifty-seven percent of the patients remained lymph node-negative and distant metastasis-negative irrespective of their depth of tumor invasion had no impact on overall survival (P = 0.49). For patients with lymph node or distant metastasis (43 percent), depth of tumor invasion had significant impact on overall survival (P = 0.001). Thirteen percent of T3N1, 33 percent of T3N2, 40 percent of T4N1, and 68.percent of T4N2 cases had distant metastasis at presentation.

Conclusion

Two types of colon cancer were observed: locally active and tendency to metastasize. For the latter, overall mortality and the risk of metastasis increased with depth of tumor invasion.

Ist die Spülung bei Bohrlochtrepanation verzichtbar?

19.06.2024 Subduralhämatom Nachrichten

Wird ein chronisches Subduralhämatom per Bohrlochtrepanation entfernt, scheint eine subdurale Ausspülung mehr Vor- als Nachteile zu haben. Das legen Ergebnisse einer finnischen Studie nahe.

Was eine zu kleine Klappe für die Langzeitprognose bedeutet

18.06.2024 Aortenklappenersatz Nachrichten

Stellt sich nach der Implantation eines biologischen Aortenklappenersatzes die Prothese als zu klein für den Patienten heraus, hat das offenbar nur geringe Auswirkungen auf Langzeitüberleben und Reoperationsrisiko; zumindest solange die effektive Öffnungsfläche über 0,65 cm2/m2 liegt.

Antibiotika nach Appendektomie: Ist kürzer besser?

18.06.2024 Appendizitis Nachrichten

Nach einer Appendektomie wegen komplizierter Appendizitis scheint eine maximal dreitägige Antibiotikabehandlung hinreichend vor Komplikationen wie intraabdominellen Abszessen und Wundinfektionen zu schützen.

TAVI bei kleinem Aortenklappenanulus: Es gibt noch ungeklärte Fragen

13.06.2024 TAVI Nachrichten

Zwischen selbstexpandierenden und ballonexpandierbaren TAVI-Klappen scheinen bezüglich der Klappenfunktion bei Aortenstenose und kleinem Aortenklappenanulus Unterschiede zu bestehen. Aber sind die überhaupt von klinischer Relevanz? Eine neue Studie liefert dazu Informationen.

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.

Das Webinar beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
