Selected AbstractsRecent incidence trends and sociodemographic features of oesophageal and gastric cancer types in an English regionALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2009C. GAJPERIA Aliment Pharmacol Ther,30, 873,880 Summary Background, Oesophageal and gastric cancers comprise various common tumour types with possible different aetiology and historically different incidence trends. Aim, To enhance and update evidence about the descriptive epidemiology of oesophageal and gastric cancers. Methods, Population-based information from the East of England was available on 16 319 (65% male) incident cases of oesophago-gastric cancer (ICD-10 C150,169) diagnosed during 1995,2006. Age-standardized incidence trends by gender and deprivation groups and sex ratios were compared for four different tumour types [oesophageal squamous cell carcinoma (OSCC), oesophageal adenocarcinoma (OAC), junctional/cardia adenocarcinoma (JCA), and non-cardia gastric adenocarcinoma (NCGA)]. Results, Between 1995,1997 and 2004,2006, the age-standardized incidence of OAC and JCA increased slightly (by 4% and 6% in men and 17% and 8% in women respectively), with a sex ratio >4 for both. Conversely, OSCC and NCGA incidence decreased (,20% and ,32% in men and ,15% and ,26% in women respectively), with sex ratio of <2 for both. In men, OSCC and NCGA incidence was associated with increasing deprivation. Conclusions, Within the study context, there was a modest rise in OAC and JCA incidence. OAC and JCA share common incidence trends and sociodemographic features (contrasting with those of OSCC and NCGA cancers).

Due to their malignant potential, they must be carefully differentially and promptly treated. A recurrence rate of approximately 30% leads to the need for monitoring of patients even after successful treatment. This article presents several cases of CIN and reviews their histopathology, aetiology, appearance, differential diagnosis and management. Typical patient presentations and prognoses are also discussed. [source] Canine neoplasia , Introductory paperAPMIS, Issue 2008HANS GAMLEM The paper gives a brief introduction to canine oncology, including its comparative aspects as basis for recording tumours in the animal kingdom. In an abbreviated presentation of the Norwegian Canine Cancer Project for the years 1990 , 1998, the data (n=14,401) were divided into age groups, each of two years, into different categories of tumours, and into age and gender. As expected, cutaneous histiocytoma was the dominant tumour type in both sexes during the two first years of life. In the age group 2 , 3.99 years histiocytoma was still the largest group in males, but was surpassed by benign epithelial skin tumours in females. After the age of 4 years, benign epithelial skin tumours constituted the greatest circumscribed group in males, and mammary tumours in females, although the summated other tumours, not explained in this survey, dominated overall in males. Maligancies (cancer) were shown in the same way, by corresponding groups of gender and age. While mastocytoma was the most common tumour and non-Hodgkin's lymphoma the second most common during the two first years of life in females, the situation was reversed in males. Later, mammary tumours dominated in females, while different tumour types not further specified in this summarized report dominated in males, until the end of the age registration (above 14 years). Number, sex and location of most common tumours are shown in a tabular outline. Comparative aspects between human and dog tumours are considered: mammary and testicular neoplasia seemed more frequent in dogs than in humans in Norway, while intestinal, pulmonary and prostatic malignancies were less common in dogs. In our study, vascular tumours and tumour-like lesions constituted about 3% of the total data. As benign vascular tumours are incompletely reported to the human Cancer Registry, no dependable comparison may be made, but malignant vascular tumours have been on the rise during the last decades in the Norwegian human population, more so in men then in women. Finally, the article deals briefly with the development of endothelial cells, and the sparse information on causal factors of vascular tumours. [source] Advances in the diagnosis and management of cutaneous mast cell tumours in dogsJOURNAL OF SMALL ANIMAL PRACTICE, Issue 8 2007J. M. Dobson Mast cell tumours are one of the most common tumours of the canine skin and have a reputation for being difficult to manage because of their variable clinical presentation, behaviour and response to treatment. This review of recent literature on canine mast cell tumours suggests that the majority of such tumours may not be as bad as their reputation suggests. Most grade I and grade II tumours can be managed successfully by good surgery. Recent literature also calls into question the utility of clinical staging systems and the value of assessing surgical margins for prognosis and highlights the paucity of well-conducted, case-controlled clinical trials in assessing the efficacy of medical management of high-risk tumours. In terms of more basic research, recent studies have implicated the stem cell factor receptor KIT as having a role in the aetiology of canine mast cell tumours and there appears to be an association between c-kit mutation and higher grade of tumour. This may offer a possible target for new therapeutic approaches.
