IL-6 serum levels predict postoperative morbidity in gastric cancer patients.

BACKGROUND: Despite progress in surgical techniques and perioperative care, gastrectomy remains a procedure of significant morbidity. Several scoring systems and clinical measures have been adopted to predict postoperative complications in gastric cancer patients. The aim of this study was to investigate whether high serum levels of interleukin 6 (IL-6) in the early postoperative period may be a prognostic factor of postoperative morbidity. METHODS: A group of 99 consecutive patients with resectable gastric cancer were enrolled. The mean age was 62.9 years and the male/female ratio was 72:27. Subtotal gastric resection was performed in 22 patients and total gastric resection in 77. The IL-6 serum level was measured on the 1st postoperative day (POD). RESULTS: Complications were recorded in 28 patients (28.3%). The observed case-fatality rate was 3.03%. An IL-6 serum level of >288.7 pg/ml on the 1st POD in univariate and multivariate Cox proportional hazard models was an independent prognostic factor for overall complications and infective complications. CONCLUSION: Our study showed an association between perioperative IL-6 serum levels and postoperative morbidity in gastric cancer patients. The IL-6 serum level on the 1st POD was shown to be an independent prognostic factor for both overall complications and infective complications.

Ludwik Rydygier--contributor to modern surgery.

Modern surgery is usually considered to have begun in nineteenth century Europe. One of the most famous contributors to gastric cancer surgery was the Polish surgeon Ludwik Rydygier, born in 1850. He initiated new methods in several fields, such as gastrointestinal surgery, orthopedics, gynecology, and urology. He was the second surgeon in the world to perform an antral resection, which he carried out on November 16, 1880. The patient, a 64-year-old man, suffered from pyloric cancer and died 12 hours after the procedure as a result of postoperative shock. The next pyloric resection was performed by Billroth in Vienna in 1881. In the nineteenth century few gastric resections were performed for peptic ulcer. The first successful antral resection for gastric ulcer penetrating to the pancreas was also performed by Ludwik Rydygier, in 1881. For many years Rydygier advocated resection in the treatment of gastric ulcers, although it was considered too dangerous for benign disease. He eventually proposed four indications for gastric resection: antral cancer, gastric ulcer, perforated gastric ulcer, and bleeding ulcers. Another operation performed for the first time by Ludwik Rydygier was gastroenterostomy, in a patient with a duodenal ulcer. In the following years other types of partial gastric resection and total gastrectomy were introduced. In 1992 the Ludwik Rydygier Association was founded in Krakow to commemorate the achievements of and pay tribute to this great surgeon. The Eighth International Gastric Cancer Congress will take place in 2009 in Krakow, where Ludwik Rydygier built a new surgical clinic in 1889.
