Gastritis OLGA-staging and gastric cancer risk: a twelve-year clinico-pathological follow-up study

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2010
M. RUGGE
Aliment Pharmacol Ther,31, 1104,1111 Summary Background, Intestinal-type gastric cancer (GC) still ranks among the high-incidence, highly lethal malignancies. Atrophic gastritis is the cancerization field in which GC develops. The current histological reporting formats for gastritis do not include any (atrophy-based) ranking of GC risk. Aim, To test the gastritis OLGA-staging (Operative Link for Gastritis Assessment) in prognosticating neoplastic progression. Methods, Ninety-three Italian patients were followed up for more than 12 years (range: 144,204 months). Clinical examinations, pepsinogen serology, endoscopy and histology (also assessing Helicobacter pylori status) were performed both at enrolment (T1) and at the end of the follow-up (T2). Results, All invasive or intra-epithelial gastric neoplasia were consistently associated with high-risk (III/IV) OLGA stages. There was a significant inverse correlation between the mean pepsinogen ratio and the OLGA stage (test for trend; P < 0.001). OLGA-staging at T1 predicted both the OLGA stage (Kaplan,Maier log-rank test, P = 0.001) and the neoplasia at T2 (Kaplan,Maier log-rank test, P = 0.001). Conclusions, This long-term follow-up study provides the first evidence that gastritis OLGA-staging conveys relevant information on the clinico-pathological outcome of gastritis and therefore for patient management. According to OLGA-staging and H. pylori- status, gastritis patients could be confidently stratified and managed according to their different cancer risks. [source]

Oncoproteomics of hepatocellular carcinoma: from cancer markers' discovery to functional pathways

LIVER INTERNATIONAL, Issue 8 2007
Stella Sun
Abstract Hepatocellular carcinoma (HCC) is a heterogeneous cancer with no promising treatment and remains one of the most prevailing and lethal malignancies in the world. Researchers in many biological areas now routinely identify and characterize protein markers by a mass spectrometry-based proteomic approach, a method that has been commonly used to discover diagnostic biomarkers for cancer detection. The proteomic research platforms span from the classical two-dimensional polyacrylamide gel electrophoresis (2-DE) to the latest Protein Chip or array technology, which are often integrated with the MALDI (matrix-assisted laser-desorption ionization), SELDI (surface-enhanced laser desorption/ionization) or tandem mass spectrometry (MS/MS). New advances on quantitative proteomic analysis (e.g. SILAC, ICAT, and ITRAQ) and multidimensional protein identification technology (MudPIT) have greatly enhanced the capability of proteomic methods to study the expressions, modifications and functions of protein markers. The present article reviews the latest proteomic development and discovery of biomarkers in HCC that may provide insights into the underlying mechanisms of hepatocarcinogenesis and the readiness of biomarkers for clinical uses.

OUTCOMES AFTER OESOPHAGOGASTRECTOMY FOR CARCINOMA OF THE OESOPHAGUS

ANZ JOURNAL OF SURGERY, Issue 1-2 2007
Mark Omundsen
Background: Carcinoma of the oesophagus is a rare but a highly lethal malignancy. The incidence of adenocarcinoma in particular is increasing in the Western world. Despite improvements in staging, perioperative care and the use of adjuvant/neoadjuvant regimen the prognosis remains poor. Methods: All patients who had biopsy-proven oesophageal carcinoma between the years 1992 and 2004 in the Wellington region, New Zealand, were retrospectively reviewed. The personal and tumour characteristics, operation details, complications and the details of hospital stay of patients who had had a resection were recorded in a database . Survival data were recovered from the notes, hospital database or general practitioner records and were available for all patients who had surgery. Survival analyses were calculated using Kaplan,Meier estimates. Results: One hundred and ninety-one patients were diagnosed with oesophageal carcinoma during the study period (59% adenocarcinoma, 32% squamous cell carcinoma). Only 35% (n = 67) had a resection (81% adenocarcinoma, 13% squamous cell carcinoma). Fifty-one (77%) had an Ivor Lewis procedure, 9 (14%) had only a laparotomy and 6 (9%) had a laparotomy, right thoracotomy and cervical incision. Forty-six (70%) tumours were in the distal third of the oesophagus and 13 (20%) were at the oesophagogastric junction. Perioperative mortality was 10% (n = 7) and anastomotic leak rate 9% (n = 6). Five-year survival was 23%. Conclusion: Results from our institution for the resection of oesophageal cancer compare favourably with those in the published work. Staging with computed tomography and laparoscopy has resulted in acceptable resection and survival rates. Survival for this disease is still largely stage dependent and earlier diagnosis probably holds the key to improved prognosis. [source]

Findings on the impact of treatment for childhood acute lymphoblastic leukaemia on family relationships

CHILD & FAMILY SOCIAL WORK, Issue 3 2001
Pam McGrath
ABSTRACT Paediatric acute lymphoblastic leukaemia (ALL) has provided a landmark in cancer therapy as the first disseminated and otherwise lethal malignancy to be curable in the majority of patients. Although the success rate is high, this benefit is achieved through a long, invasive and very arduous treatment process. The experience of undergoing such intensive treatments affects not only the child, but the entire family. To date, however, psychosocial research is only beginning to describe the depth and breadth of the impact on families of this experience. This paper presents findings from a recent qualitative study of families coping with the initial stage (induction remission) of treatment for childhood ALL. The findings indicate that the experience is so profoundly disturbing and disruptive that it challenges the families' sense of normalcy and stability. These findings provide evidence of significant hardship and stress, with the consequent indication of the need for social work support. Above all, such families need to hear the comforting message from social workers that what they are experiencing is normal under the circumstances. Along with practical assistance, they need reassurance about the intensity of feelings they will experience and an affirmation of the difficulty of the challenges they face. [source]
