Neoadjuvant radiochemotherapy for locally advanced gastric cancer: a phase I-II study
Background: To study in a phase I-II trial the maximum tolerated dose, the toxicity, and the tolerance of adding radiotherapy to systemic chemotherapy administered preoperatively in patients with locoregionally advanced gastric adenocarcinoma. Patients and methods: Patients with adenocarcinoma of the stomach (T3-4Nany or TanyN+), performance status ≤1, normal hematological, hepatic and renal functions received two cycles of cisplatin 100 mg/m2 on day 1, 5-FU 800 mg/m2 on days 1 to 4 and leucovorin 60 mg b.i.d. on days 1 to 4 q3w, concomitantly with radiation therapy escalated in three dose tiers (31.2, 38.4 and 45.6 Gy). Results: Nineteen patients were accrued and 18 completed neoadjuvant therapy. Major toxicity consisted of grade 3/4 leucopenia and mucositis in 89% and 36% of the patients, respectively. Only one episode of febrile neutropenia was recorded. Dose level number 2 (38.4 Gy) with the chemotherapy given q4w is the recommended dose level. All patients were subsequently operated and no fatalities occurred. Pathological assessment showed one complete and eight partial responses. Two- and 3-year relapse-free survival rates were 57% and 50%, respectively. Only one patient relapsed locally. The peritoneum was the most frequent site of relapse. Conclusions: This neoadjuvant therapeutic program is relatively well tolerated, does not seem to increase the operative risk, and might increase the locoregional control of the disease. The frequency of peritoneal involvement in relapsing patients underscores the need for a more effective systemic treatmen
Cyclin D1, cyclin E, and p21 have no apparent prognostic value in anal carcinomas treated by radiotherapy with or without chemotherapy
The purpose of this study was to assess the potential prognostic and/or predictive value of the expression of cyclin D1, cyclin E, and p21 protein in a series of 98 anal carcinomas (T1-4, N0-3) treated by radiotherapy with (51) or without (47) chemotherapy in one institution. Correlation with Mib1 index and p53 expression was also investigated. Median follow-up for surviving patients was 124 months (range: 30-266). Immunohistochemical staining was performed on pretreatment biopsies, applying a standard ABC technique for cyclin D1 (clone DSC6, DAKO, 1 : 300), cyclin E (clone 13A3, Novocastra, 1 : 100), p21(WAF/CIP1) (clone SX118, DAKO, 1 : 50), p53 (clone DO7, DAKO, 1 : 200), and Mib1 (Ki-67, Dianova, 1 : 20). Tumours were classified into low- or high-expression groups according to the expression level of the protein considered. High expression was found in 51% of tumours for cyclin E, in 33.7% for cyclin D1, and in 65% for p21. None of those factors were significantly associated with clinical variables such as advanced T or N categories. In a monovariate analysis, advanced T and N categories and longer overall treatment time were the only variables that correlated significantly with low rate of local control (LC) and disease-free survival. However, in a subgroup analysis, high p21 expression correlated with a trend for significantly higher 5-year LC (87 vs 68%, P=0.07) in the N0 patients. The results of this study suggest that the cell-cycle proteins investigated are unlikely to be clinically useful in predicting treatment response or prognosis in patients with anal carcinomas
Extracorporeal Membrane oxygenation in neonates and children
Extracorporeal membrane oxygenation (ECMO) is a general term that describes the short- or long-term support of the heart and/or lungs in neonates, children and adults. It offers a treatment option for severe cardiac and/or respiratory failure from neonate to adult. Used as venoarterial extracorporeal membrane oxygenation (VA-ECMO), it remains the most commonly used modality for short- to mid-term mechanical support of the failing circulation in children. The aim of this article is to review the clinical indications, different circuits, technical options, patient management, and potential risks and benefits of this therapy for children. As ECMO therapy is an overwhelming event for the whole family we also highlight the role of psychosocial counselling and support for the parents
Primary malignant melanoma of the esophagus
A case of primary malignant melanoma of the esophagus is reported, followed by a review of the literature. The clinical presentation of this uncommon tumor is similar to esophageal carcinoma and the preoperative diagnosis may be difficult. A total esophagectomy is the treatment of choice. The prognosis remains poor despite aggressive treatment
