Lokalrezidive nach Rectumcarcinom — Entstehung, Diagnose, Prognose

Paul Hermanek; F. P. Gall; A. Altendorf

SummaryLocal recurrences following curative surgery for rectal carcinoma were observed in 167 out of a total of 729 patients (22.9%). The rate of local recurrences was related to the horizontal spread of the tumor (insular/circular, largest tumor diameter), to the macroscopic pattern of growth, and to the Dukes classification. The frequency of local recurrences following anterior and deep anterior resection of the rectum was significantly dependent on the extent of the aboral margin of clearance. Generally speaking, a margin of more than 30 mm is recommended for the anterior and deep anterior resection, measured on the fresh specimen without tension. The rate of local recurrence increases if a local tumor cell dissemination occurs during the operation as a result of an incision through the tumor tissue or an opening of the rectum in the area of the tumor. 90% of the local recurrences were diagnosed within the first two postoperative years. Curative reoperation of local recurrences was possible in 30% (25/82) following anterior and deep anterior resection, but only as an exception (1/74) following abdomino-perineal resection. The age-corrected 5 year survival rate (including postoperative mortality) was 74% for patients without local recurrence, however, only 12% for those with local recurrence. If the local recurrence proved to be operable for cure, a five year survival rate of 33% could still be attained. A reduction of local recurrences can be achieved by careful differentiation of the indications for limited operative procedures (endoscopic polypectomy, local surgical excision, segmental resection), and for anterior resection or abdomino-perineal resection as well as by careful operative technique and especially by avoiding an intraoperative dissemination of tumor cells. With the help of frequent follow-ups, the earliest diagnosis of possible local recurrences should be strived for, in order to allow for curative reoperation.ZusammenfassungNach kurativer Operation von Rectumcarcinomen wurden bei 167 von 729 Patienten (22,9%) Lokalrezidive beobachtet. Die Lokalrezidivrate wird von verschiedenen therapieunabhängigen Faktoren beeinflußt, weiters bei Rectumresektionen von der Weite des aboralen Sicherheitsabstandes sowie von einer etwaigen intraoperativen lokalen Tumorzelldissemination. Die alterskorrigierten 5-Jahres-Überlebensraten (einschließlich postoperativer Letalität) betrugen für Patienten ohne Lokalrezidive 74%, für Patienten mit Lokalrezidiven jedoch nur 12%. Wenn das Lokalrezidiv noch kurativ operabel war, konnte immerhin eine 5-Jahres-Überlebensrate von 33% erzielt werden. Durch engmaschige Nachsorge sollte eine möglichst frühzeitige Diagnose von Lokalrezidiven angestrebt werden, um etwaige Lokalrezidive noch kurativ operieren zu können.

86. Operationstaktik und Ergebnisse bei erweiterten Operationen colorectaler Carcinome

F. P. Gall; J. Tonak; A. Altendorf; U. Kuruz

SummaryBetween 1969 and 1983 a total of 1918 patients with colorectal carcinoma were curatively operated. In 121 of these patients a curative procedure could be achieved despite tumor invasion of adjacent organs by extending the operation to include these involved structures. In 45% of these patients the histological examination revealed that there were only peritumoröus inflammatory adhesions while in 55% of the cases a direct tumor invasion of the neighbouring organ was present. The 5-year-survival-rate in the 121 patients was 44%. The operative mortality of 12% (14 out of 121) is included. The final results were considerably worse if the tumor could not be removed en bloc.ZusammenfassungZwischen 1969 und 1983 wurden 1918 Patienten mit colorectalen Carcinomen kurativ operiert. Unter diesen wurde bei 121 Patienten wegen makroskopischen Tumorbefalls von Nachbarorganen eine erweiterte Resektion vorgenommen. Bei der pathohistologischen Begutachtung der Präparate zeigte sich, daß in 55% die mitentfernten Organe tatsächlich tumorbefallen waren, während bei 45% der Patienten nur peritumoröse entzündliche Adhaesionen vorlagen. Die 5-Jahres-Überlebensrate der 121 Patienten betrug 44%. Die postoperative Letalität von 12% (14 von 121) ist eingeschlossen. Die Heilergebnisse waren deutlich schlechter, wenn der Tumor nicht en bloc entfernt werden konnte.Between 1969 and 1983 a total of 1918 patients with colorectal carcinoma were curatively operated.

[Prediction of local recurrences after surgery of carcinoma of the middle reticulum (author's transl)].

Paul Hermanek; W. Gunselmann; A. Altendorf; F. P. Gall; L. Horbach

SummaryOn the basis of completely and exactly documented follow-up data of 237 patients on whom carcinomas of the middle rectum were resected for cure, a multivariate statistical model was developed and the corresponding parameters were calculated. With this model the individual risk of local recurrences can be estimated after anterior resection with a small margin of clearance (11–30 mm on the fresh specimen without stretching), after anterior resection with a wide margin of clearance (more than 30 mm), and after excision of the rectum. Seven prognostic factors are taken into consideration that can be determined pre- and intraoperatively. Estimations of the risk of local recurrences on the basis of observed and documented follow-up data can be used as decisive factor for differential indication between restorative and excisional surgery on future patients. After anterior resection the risk of local recurrences is calculated according to macroscopic findings on the specimen and to frozen section histology. If the risks in anterior resection and excision are approximately equal, the resection is ended by anastomosis; otherwise the operation will be extended to excision of the rectum. This statistical model enables the surgeon to select the proper operative procedure for each individual situation (histology-and stage-adapted surgery).ZusammenfassungAufgrund der vollständig und sorgfältig dokumentierten Verlaufsdaten von 237 kurativ operierten Patienten mit Carcinomen des mittleren Rectumdrittels wurde ein multivariates statistisches Modell entwickelt und dessen Parameter bestimmt. Damit kann das individuelle Risiko von Lokalrezidiven nach Rectumresektion mit engem Sicherheitsabstand (11–30 mm am frischen Resektat ohne Zug gemessen), nach Rectumresektion mit weitem Sicherheitsabstand (mehr als 30 mm) und nach Rectumexstirpation geschätzt werden. Sieben prä- und intraoperativ bestimmbare prognostische Faktoren werden hierbei berücksichtigt. Die Schätzungen des Rezidivrisikos auf der Basis beobachteter und dokumentierter Verläufe sind als Entscheidungshilfen bei der Differentialindikation Resektion/Exstirpation bei künftigen Patienten verwertbar. Wenn eine Resektion vorgenommen wird, kann nach makroskopischer Beurteilung des Resektionspräparates unter Mitberücksichtigung der Schnellschnittergebnisse noch intraoperativ das Rezidivrisiko anhand des Modells berechnet werden. Ergeben sich bei Resektion und Exstirpation annähernd gleiche Rezidivrisiken, wird die Resektion durch Anastomosierung abgeschlossen, andernfalls die Operation zur Rectumexstirpation erweitert. Das vorgestellte Modell bietet die Möglichkeit, das Operationsverfahren der individuellen Situation anzupassen (histologie- und stadiengerechte Therapie).

Typical and Atypical Resection Techniques of Hepatic Metastases

F. P. Gall; J. Scheele; A. Altendorf

This report deals exclusively with liver metastases from colorectal cancer, since our experience with hepatic metastases from other primary tumors is very limited.

183. Die kurative Metastasenresektion an der Leber bei colorectalem Carcinom. Indikation, Technik, Grenzen

J. Scheele; F. P. Gall; A. Altendorf; Dietrich H. Hornig

SummaryBetween 1969 and 1983, a total of 94 patients underwent resection of liver metastases from colorectal carcinoma, which was undertaken for curative purposes. Techniques included typical resection with or without preliminary extrahepatic vascular ligation, atypical resection, and wedge excision. The 5-year survival following radical liver resection was 30% in 75 patients. The most important prognostic factor was lymph-node involvement at the primary tumor site. In 19 patients with histologically proven tumor invasion of the resection area (classified as nonradical procedures), the longterm results were similar to these of 42 patients undergoing regional chemotherapy of widespread liver metastases.ZusammenfassungVon 1969 bis 1983 wurden bei 94 Patienten Lebermetastasen eines colorectalen Carcinoms in kurativer Absicht reseziert. Neben anatomiegerechten Resektionen mit oder ohne präli-minare Hilusdissektion kamen atypische Resektionen und Excisionen zur Anwendung. Die 5-Jahres Überlebensrate nach radikaler Tumorentfernung bei 75 Patienten war 30%. Als wichtigster prognostischer Faktor erwies sich die Lymphknoteninfiltration im Bereich des Primärtumors. Bei 19 Patienten mit histologisch nachgewiesener Tumorinfiltration der Resektionsfläche entsprach die Langzeitprognose der nach regionaler Chemotherapie diffuser Lebermetastasen bei 42 Patienten.

386. Operative Therapie des Pankreascarcinoms

Ch. Gebhardt; F. P. Gall; Paul Hermanek; Hubert Zirngibl; A. Altendorf

SummaryReport on 417 operations for periampullary and ductal pancreatic cancer. Between 1979 and 1981 the resection rates were increased to 85 % and 29 %, respectively. Prognosis for periampullary carcinoma was better than for ductal pancreatic cancer because the diagnosis was established at an earlier tumor stage. However, in cases with pNO (without lymph node metastases) we found a median survival time of more than 60 months for the periampullary as well as the ductal carcinoma cases.ammenfassungBericht über 417 Eingriffe wegen periampullärer und duktaler Pankreascarcinome. Die Resektionsquoten konnten in den Jahren 1979–1981 auf 85 % bzw. 29 % angehoben werden. Die Prognose des periampullären Carcinoms war nur günstiger als die des duktalen Carcinoms, weil die Diagnose in einem früheren Tumorstadium gestellt wurde. Bei pNO, also fehlenden Lymphknotenmetastasen, lag die mediane Überlebenszeit beim periampullären und duktalen Carcinom über 60 Monate.

182. Lokalrezidive nach Rectumcarcinom. Entstehung, Frühdiagnose, Prognose

Paul Hermanek; F. P. Gall; A. Altendorf

SummaryAbout 55% of all local recurrences after surgery for rectal carcinoma are observed within the first year and about 35% during the second year. The frequency of local recurrences is influenced by various factors, of which the histopathological stage of the tumor and — in anterior and deep anterior resection — the aboral margin of clearance are of greatest importance. Prognosis is crucially worsened by a local recurrence. Follow-up examinations at close intervals allow an early diagnosis, and in this case curative radical reoperations are possible. (Supported by DFG, SFB 118)ZusammenfassungEtwa 55% aller Lokalrezidive nach Rectumcarcinom treten im 1. Jahr, etwa 35% im 2. Jahr nach der Operation auf. Die Häufigkeit von Lokalrezidiven wird von verschiedenen Faktoren beeinflußt. Von besonderer Bedeutung ist das histopathologische Stadium des Tumors, bei Rectumresektionen zusätzlich die Weite des aboralen Sicherheitsabstandes. Das Auftreten eines Lokalrezidivs verschlechtert die Prognose entscheidend. Engmaschige Kontrolluntersuchungen ermöglichen eine frühe Diagnose von Lokalrezidiven und dann unter Umständen noch eine kurative radikale Reoperation. (Mit Unterstützung durch die DFG, SFB 118.)
