Cryptogenic organizing pneumonia in Sweet's syndrome: case report and review of the literature.

BACKGROUND AND AIMS: Sweet's syndrome or acute febrile neutrophilic dermatosis is characterized by fever, leukocytosis and tender erythematous plaques, which show infiltration by mature neutrophils on histological examination. Pulmonary involvement is rare in Sweet's syndrome. METHOD: We describe the case of a 17-year-old man with a myelodysplastic syndrome following therapy for Hodgkin's lymphoma who developed Sweet's syndrome and cryptogenic organizing pneumonia. In addition, we conducted a review of the related English literature. RESULTS: Literature review yielded six similar reports of biopsy-proven cryptogenic organizing pneumonia associated with Sweet's syndrome. We present the clinical and laboratory characteristics, as well as the response to treatment, of all cases of cryptogenic organizing pneumonia reported in patients with Sweet's syndrome. CONCLUSIONS: Cryptogenic organizing pneumonia is a rare manifestation of Sweet's syndrome, which may be complicated by respiratory failure. Prompt treatment with corticosteroids usually leads to clinical and radiographic improvement.

Evaluation of the prognostic and predictive value of HER-1/EGFR in breast cancer patients participating in a randomized study with dose-dense sequential adjuvant chemotherapy.

BACKGROUND: To assess the prognostic and predictive significance of HER-1/EGFR protein levels in high-risk patients with breast cancer treated with dose-dense sequential adjuvant chemotherapy. METHODS: 595 high-risk breast cancer patients were treated with adjuvant anthracycline-based dose-dense sequential chemotherapy (E-CMF vs. E-T-CMF). Disease-free survival (DFS) was the primary end point. HER-1/EGFR was assessed by immunohistochemistry (IHC) in 312 patients. RESULTS: HER-1/EGFR expression was detected in 54 of 312 patients (17%). Positive expression of HER-1/EGFR was significantly associated with negative receptor status (52 vs. 17%, p < 0.001), worse histological grade (70 vs. 45%, p = 0.001), HER-2 overexpression (46 vs. 27%, p = 0.01) and positive p53 expression (48 vs. 19%, p < 0.001). With a median follow-up of 7 years, the total number of relapses was 105 (34%), and the total number of deaths 69 (22%). The analysis for DFS provides significant evidence that the HER-1/EGFR effect on the risk of disease progression was different according to treatment (interaction p = 0.02). Regarding overall survival, a trend towards a significant difference for an interaction of HER-1/EGFR and treatment was found (p = 0.07). CONCLUSION: The present study demonstrated a differential effect of positive HER-1/EGFR expression in the two treatment groups, with HER-1/EGFR being a negative prognostic marker in the absence of paclitaxel.

Two-stage liver surgery for advanced liver metastasis synchronous with colorectal tumor.

BACKGROUND/AIMS: To evaluate the efficacy of two-stage surgery and multidisciplinary approach, in the treatment of primary colorectal cancer, synchronous with advanced liver metastases. METHODOLOGY: Sixty-two patients who underwent two-stage surgery for advanced metastatic liver disease synchronous with colorectal tumor were studied. In the first-stage surgery, the primary colorectal tumor was resected. Depending on the location of the main tumor mass, ligation and transection of the relevant (right or left) main portal vein branch was done. Subsequently, the metastatic nodules in the contralateral lobe were ablated by microwave therapy. An arterial jet port catheter was also introduced into the hepatic artery via the gastroduodenal artery for locoregional chemoimmunotherapy. Two days after the first-stage surgery locoregional transarterial targeting chemoimmunotherapy was given. The second-stage hemihepatectomy was carried out forty to forty-five days after the initial surgery. As an adjuvant treatment locoregional targeting chemoimmunotherapy was carried out in all patients via the arterial chemoport. RESULTS: Mean survival was 66+/-4 months. There were no operative deaths. CONCLUSIONS: Two-stage liver surgery including, portal vein branch ligation, microwave ablative therapy and transarterial targeting locoregional chemoimmunotherapy is the best treatment for advanced, synchronous metastatic liver disease of colorectal origin. It results in an increase in the overall survival of these patients with good postoperative quality of life, which encourages the hepato-biliary surgeon to venture upon this herculean task thus increasing the resectability rate of the tumor.

Mono-bloc total spleno-pancreaticoduodenectomy for pancreatic head carcinoma with portal-mesenteric venous invasion. A prospective randomized study.

BACKGROUND/AIMS: To evaluate, the early and long-term results of mono-bloc spleno-pancreatic and vascular resection for advanced carcinoma of the head of the pancreas, with portal-mesenteric venous invasion. METHODOLOGY: In a prospective, randomized trial, fifty-six patients with advanced carcinoma of the head of the pancreas with vascular invasion were studied. Patients were randomly divided in two groups A and B. Group A patients underwent an en-bloc spleno-pancreatic and vascular resection. Group B patients underwent a palliative gastro-biliary bypass. Patients in both groups were subjected to adjuvant locoregional chemoimmunotherapy, through an arterial catheter introduced into the superior mesenteric artery via a jejunal arterial branch. RESULTS: The 2- and 5-year survival rates for Group A patients were 81.8% and 18.5%. The respective percentages for disease-free survival were 60.6% and 0%. Two-year survival for group B was nil. CONCLUSIONS: Mono-bloc spleno-pancreaticoduodenectomy and regional vascular resection and reconstruction, with adjuvant locoregional chemoimmunotherapy leads to substantial prolongation of survival and optimization of quality of life.

New frontiers in the management of advanced hepatocellular carcinoma. "A new look to an old problem".

BACKGROUND/AIMS: To evaluate the benefits of two-stage liver surgery with main portal branch ligation and transection combined with transarterial targeting locoregional neo and adjuvant immunochemotherapy in patients suffering from hepatocellular carcinoma. METHODOLOGY: 43 consecutive patients underwent two-stage liver surgery for advanced hepatocellular carcinoma. First we performed ligation and transection of the main portal vein branch corresponding to the liver lobe occupied by the tumor. Subsequently we introduced an arterial jet port catheter towards the hepatic artery via the gastroduodenal artery. After locoregional transarterial targeting immunochemotherapy regimen the patient underwent a second laparotomy for hemihepatectomy. Following surgery, locoregional transarterial targeting immunochemotherapy was given to all patients via the arterial port of the gastroduodenal artery as an adjuvant treatment. RESULTS: Mean survival was 41 months. There were no operative deaths. CONCLUSIONS: Two-stage liver surgery and transarterial targeting locoregional immunochemotherapy is the favorable option of treatment for advanced hepatocellular carcinoma. It not only results in an increase in the overall survival of these patients, but also increases the rate of resectability of these tumors by the hepatobiliary surgeon.
