Clinical relevance of soluble c-erbB-2 for patients with metastatic breast cancer predicting the response to second-line hormone or chemotherapy

Concentrations of soluble c-erbB-2 were determined in the sera of 64 patients with distant metastasis from advanced breast cancer receiving second-line hormone or chemotherapy in comparison to 35 breast cancer patients without detectable recurrent disease and 17 healthy blood donors. The sera of non-metastatic breast cancer patients contained s-erbB-2 concentrations similar to those of healthy blood donors. Patients with distant metastasis from advanced breast cancer had significantly higher values of s-erbB-2 in comparison to patients with non-disseminated disease (mean: 59.6 vs. 11.6 U/ml; p = 0.022). A significant correlation was observed between s-erbB-2 serum levels and serum LDH concentrations (p < 0.001), levels of alkaline phosphatase (p < 0.001), and the presence of hepatic metastasis (p = 0.001). Time to tumor progression was significantly shorter in patients with s-erbB-2 levels above 40 U/ml (mean: 23.4 vs. 56.7 months; p = 0.002). Furthermore, breast cancer patients with hepatic metastasis and those with elevated s-erbB-2 serum levels above 40 U/ml had limited response to hormone or chemotherapy. Non-responders had significantly higher s-erbB-2 levels (mean: 270.3, range: 42-500 U/ml;) compared with the responder group (mean: 23.1, range: 0-149 U/ml; p < 0.001). Logistic regression analysis indicated that elevated s-erbB-2 serum levels above 40 U/ml independently predicted an unfavorable response to second-line hormone or chemotherapy in patients with advanced metastatic breast cancer.

Vacuum assisted closure in coloproctology

Vacuum-assisted closure has earned its indications in coloproctology. It has been described with variable results in the treatment of large perineal defects after abdominoperineal excision, in the treatment of stoma dehiscence and perirectal abscesses. The most promising indication for vacuum-assisted closure is probably the treatment of para-anastomotic presacral abscesses following anastomotic leakage after total mesorectal excision. Early initiation of vacuum-assisted closure has the potential to prevent debilitating persistent presacral sinuses precluding stoma closure and bad function of the neorectum. Prompt initiation of endosponge treatment is advised after the anastomotic leakage with the purulent cavity is diagnosed. The endosponge is inserted transanally and connected with a low vacuum bottle. With the gradual reduction in the cavity, the endosponge is reduced in size every 3–4 days when the endosponge is exchanged. It takes 3–6 weeks to close the cavity. Future studies should focus on the stoma closure rate and function to assess whether this intensive postoperative treatment of anastomotic leakages is justified

Percutaneous endoscopic gastrojejunostomy for a patient with an intractable small bowel injury after repeat surgeries: a case report

<p>Abstract</p> <p>Introduction</p> <p>The management of intestinal injury can be challenging, because of the intractable nature of the condition. Surgical treatment for patients with severe adhesions sometimes results in further intestinal injury. We report a conservative management strategy using percutaneous endoscopic gastrojejunostomy for an intractable small bowel surgical injury after repeated surgeries.</p> <p>Case presentation</p> <p>A 78-year-old Japanese woman had undergone several abdominal surgeries including urinary cystectomy for bladder cancer. After this operation, she developed peritonitis as a result of a small bowel perforation thought to be due to an injury sustained during the operation, with signs consistent with systemic inflammatory response syndrome: body temperature 38.5°C, heart rate 92 beats/minute, respiratory rate 23 breaths/minute, white blood cell count 11.7 × 10⁹/L (normal range 4-11 × 10⁹/μL). Two further surgical interventions failed to control the leak, and our patient's clinical condition and nutritional status continued to deteriorate. We then performed percutaneous endoscopic gastrojejunostomy, and continuous suction was applied as an alternative to a third surgical intervention. With this endoscopic intervention, the intestinal leak gradually closed and oral feeding became possible.</p> <p>Conclusion</p> <p>We suggest that the technique of percutaneous endoscopic gastrojejunostomy combined with a somatostatin analog is a feasible alternative to surgical treatment for small bowel leakage, and is less invasive than a nasojejunal tube.</p
