Allogeneic Hematopoietic Stem-Cell Transplantation Improves Disease-Free Survival Compared to Pediatric-Inspired Berlin-Frankfurt-Münster Chemotherapy in Adult Acute Lymphoblastic Leukemia.

INTRODUCTION: Acute lymphoblastic leukemia (ALL) is a malign disease with poor prognosis in adults. After remission is achieved by induction therapy, administration of allogeneic hematopoietic stem-cell transplantation (AHSCT) is one of the standard treatment in adult ALL patients. Pediatric-inspired chemotherapy has been demonstrated to improve outcomes of adult ALL. The aim of this study was to compare the Berlin-Frankfurt-Münster-95 chemotherapy (BFM-95) regimen and AHSCT results in ALL patients with first complete remission. PATIENTS AND METHODS: Forty-seven patients who received the BFM-95 regimen and 83 patients who underwent AHSCT were compared. Primary endpoints were comparison of overall survival (OS) and disease-free survival (DFS) between groups. RESULTS: There was no significant difference between the groups in terms of age, gender, or performance status. In BFM-95 and AHSCT, relapsed disease occurred in 11 (23.4%) and 24 (28.9%), respectively; the respective values for treatment-related mortality were 6 (12.7%) and 10 (12%) (P = .32 and .91). Five-year DFS was 38% with BFM-95 and 57% with AHSCT (P = .014). There was no 5-year OS difference in both groups (64% vs 60%, P = .13). While leukocyte count < 30 × 109/L at the time of diagnosis (hazard ratio, 2.7; P = .021) and prophylaxis of central nervous system (hazard ratio, 2; P = .036) were prognostic for OS, the only factor that had a prognostic effect on DFS was AHSCT (hazard ratio, 1.6; P = .041). CONCLUSION: AHSCT currently offers no special OS advantage but increases DFS compared to the BFM-95 regimen. AHSCT may be considered at first complete remission in patients at low risk of transplant-related mortality.

Clinical Value of CXCL5 for Determining of Colorectal Cancer

Background: Several studies indicate that chemokines play important roles in colorectal mucosal immunity. The chemokine CXCL5 which is expressed by epithelial cells within colorectal mucosa is a promoter of cell proliferation, migration and invasion, is a novel serum prognostic marker in patients with colorectal cancer. The purpose of this study was to investigate whether serum and tissue CXCL5 levels is altered in colorectal carcinomas (CRC) compared to colonic adenoma and normal mucosa.It also aimed to compare colon adenoma and colorectal cancer for blood CXCL5 and CEA levels, their sensitivity, and specificity. Methods: CXCL5 expression was assessed with immunohistochemistry staining in biopsy samples taken during colonoscopy in 22 colonic adenomas, 23 colorectal carcinomas and 23 normal colonic tissue samples. Also all patients' serum CXCL5 and CEA levels were measured. This stduy was prospective observational study. Results: The number of cases who were stained positive with immunohistochemistry was found to be higher in the group with CRC. When compared with the other groups, both levels of serum CXCL5 and CEA were significantly high in the group CRC. Sensitivity and specificity of serum CXCL5 were found to be low as a result of the ROC analysis. Conclusion: Although the level of CXCL5 is high in CRC, its level in serum is not significant enough to support the early diagnosis of the disease.

Old-scar mass and changing surgical perspective: Sarcoidosis.

Sarcoidosis is a systemic inflammatory disease of an unknown etiology. Skin is involved in 25% of all cases, and 29% of them present as a scar sarcoidosis. Asymptomatic old-scar masses are generally regarded as a foreign body reaction by surgeons and often result in excisional biopsy. We describe a case of a patient who developed sarcoidosis in a 34-year-old appendectomy scar and adjacent inguinal lymph nodes without any local or systemic symptom and radiologic finding. Surgeons should not underestimate the importance of such lesions as a simple condition. Scar sarcoidosis may resolve spontaneously, or the treatment with some topical agents is effective. Furthermore, scar sarcoidosis may be the initial manifestation of systemic sarcoidosis.
