Prevalence of Disorders Recorded in Dogs Attending Primary-Care Veterinary Practices in England

Purebred dog health is thought to be compromised by an increasing occurence of inherited diseases but inadequate prevalence data on common disorders have hampered efforts to prioritise health reforms. Analysis of primary veterinary practice clinical data has been proposed for reliable estimation of disorder prevalence in dogs. Electronic patient record (EPR) data were collected on 148,741 dogs attending 93 clinics across central and south-eastern England. Analysis in detail of a random sample of EPRs relating to 3,884 dogs from 89 clinics identified the most frequently recorded disorders as otitis externa (prevalence 10.2%, 95% CI: 9.1-11.3), periodontal disease (9.3%, 95% CI: 8.3-10.3) and anal sac impaction (7.1%, 95% CI: 6.1-8.1). Using syndromic classification, the most prevalent body location affected was the head-and-neck (32.8%, 95% CI: 30.7-34.9), the most prevalent organ system affected was the integument (36.3%, 95% CI: 33.9-38.6) and the most prevalent pathophysiologic process diagnosed was inflammation (32.1%, 95% CI: 29.8-34.3). Among the twenty most-frequently recorded disorders, purebred dogs had a significantly higher prevalence compared with crossbreds for three: otitis externa (P = 0.001), obesity (P = 0.006) and skin mass lesion (P = 0.033), and popular breeds differed significantly from each other in their prevalence for five: periodontal disease (P = 0.002), overgrown nails (P = 0.004), degenerative joint disease (P = 0.005), obesity (P = 0.001) and lipoma (P = 0.003). These results fill a crucial data gap in disorder prevalence information and assist with disorder prioritisation. The results suggest that, for maximal impact, breeding reforms should target commonly-diagnosed complex disorders that are amenable to genetic improvement and should place special focus on at-risk breeds. Future studies evaluating disorder severity and duration will augment the usefulness of the disorder prevalence information reported herein

Quality of life of palliative chemotherapy naive patients with advanced adenocarcinoma of the stomach or esophagogastric junction treated with irinotecan combined with 5-fluorouracil and folinic acid: results of a randomised phase III trial

41st Annual Meeting of the American-Society-of-Clinical-Oncology -- MAY 13-17, 2005 -- Orlando, FLWOS: 000268881000007PubMed ID: 19568958The quality of life (QL) of advanced gastric cancer patients receiving irinotecan, folinic acid and 5-fluorouracil (5-FU) (IF arm) or cisplatin with 5-FU (CF arm) is presented. Patients with measurable or evaluable advanced gastric cancer received IF weekly for 6/7 weeks or CF q4 weeks. QL was assessed using the EORTC QLQ-C30 at baseline, subsequently every 8 weeks until progression and thereafter every 3 months until death. The QL data were analysed using several statistical methods including summary measures and pattern-mixture modelling. A total of 333 patients were randomised and treated (IF 170, CF 163). The time-to-progression for IF and CF was 5.0 and 4.2 months (P = 0.088), respectively. The overall compliance rates for QL questionnaire completion were 60 and 56% in the IF and CF arms, respectively. Significant treatment differences were observed for the physical functioning scale (P = 0.024), nausea\vomiting (P = 0.001) and EQ-5D thermometer (P = 0.020) in favour of the IF treatment arm. There was a trend in favour of IF over CF in time-to-progression. The IF group also demonstrated a better safety profile than CF and a better QL on a number of multi-item scales, suggesting that IF offers an alternative first-line platinum-free treatment option for advanced gastric cancer.Amer Soc Clin Onco

A várandósság alatti emlőrák kezelése = Treatment of pregnancy associated breast cancer

Terhességi emlőráknak a várandósság ideje alatt, illetve a szülést követő egy éven belül kialakuló rosszindulatú emlődaganatot nevezzük. Háromezer várandós nőből körülbelül 1-ben alakul ki. A tumor incidenciája növekedő tendenciát mutat, amelyben elsősorban a gyermekvállalás egyre későbbi életkorra való kitolódása játszhat szerepet. A várandós állapot késlekedést okozhat mind a diagnózis felállításában, mind a megfelelő kezelés elindításában. Közleményünkben egy 30 éves nőbeteg esetét ismertetjük, aki első terhességének 21. hetében önvizsgálat során észlelte a jobb emlő bőrének gyulladásos elváltozását, és a hónaljárokban levő megnagyobbodott nyirokcsomókat. Az antibiotikus kezelésre a páciens panaszai nem javultak, ezért az axillaris képlet vékonytű-aspirációs citológiai vizsgálatát végezték el, amelynek során metasztatikus emlőrák igazolódott. A klinikánkon végzett vizsgálat során cT4 cN3 lokoregionális kiterjedésű daganatot véleményeztünk. Az emlő bőrének elváltozása gyulladásos emlőrákra utalt, emellett axillaris, valamint supraclavicularis nyirokcsomó-konglomerátumot is tapintottunk. A core-bioptátum értékelése során hormonreceptor-negatív, Her-2-pozitív, grade III differenciáltságú invazív carcinoma igazolódott. Neonatológiai és onkológiai konzíliumot követően a beteg úgy döntött, hogy a várandósság alatt elzárkózik a kemoterápiás kezeléstől, ezért a 30. gesztációs héten elektív császármetszést végeztünk. A további vizsgálatok távoli áttétet nem igazoltak, így primer szisztémás kemoterápiát kezdtünk, majd ezt követően mastectomia és axillaris blokkdisszekció történt. Az eltávolított emlőállományban visszamaradt tumort a kórszövettani vizsgálat során már nem azonosítottunk, a szöveti kép alapján komplett patológiai remissziót véleményeztünk. A sugárkezelés befejezése után trastuzumabkezelést indítottunk. Az ellenőrző vizsgálatok a páciensnél eddig sem helyi kiújulást, sem távoli áttétet nem igazoltak. Az újszülött generalizált izomtónus-eloszlási zavarok miatt jelenleg is fejlődésneurológiai gondozás alatt áll. | Pregnancy-associated breast cancer (PABC) is defined as cancer of the breast diagnosed during pregnancy and up to 1 year postpartum. The crude incidence is 1/3000 pregnant women. As women delay childbearing the incidence of PABC increases with age. Young patients with PABC do not have worse prognosis compared with those with non-PABC; however, pregnancy can contribute to a delay in breast cancer diagnosis, evaluation, and treatment. Primary care physicians and gynecologists should be careful in the thorough workup of breast symptoms in the pregnant population to expedite diagnosis and allow multidisciplinary treatment as early as possible following the established diagnosis. Authors report a case of a 30-year-old pregnant woman, who detected inflammatory signs of her right breast and a palpable axillary mass at the 21st week of gestation. Her symptoms did not improve with administration of antibiotics. Therefore fine needle aspiration biopsy of the axillary lump was performed, with the result of unequivocal diagnosis of metastatic invasive carcinoma. The patient was referred to the multidisciplinary tumor board of our Department at the 27st week of gestation with the symptoms of inflammatory breast cancer, palpable right axillary and supraclavicular lymph nodes. Core biopsy showed an ER and PR negative, Her-2 positive, grade 3, infiltrating ductal carcinoma of the breast. After multidisciplinary team consultation the patient declined any kind of therapy during her pregnancy. On the 30th week of gestation caesarean section was performed. The premature baby girl was treated in the Neonatal Intensive Care Unit. Imaging modalities revealed no evidence of distant metastases short after the delivery. After 6 cycles of chemotherapy (docetaxel-doxorubicin-cycclophosphamid) the patient underwent right mastectomy and axillary lymph node dissection. Complete pathological response was diagnosed, since no residual tumor was found in the surgical resection specimen. After radiotherapy, trastuzumab medication was initiated. To date, there is no evidence of local recurrence or distant metastases during her 24 months follow-up. The newborn is on close neurohabilitation folow-up due to the evidence of generalized muscle dystonia. Had the patient accepted chemotherapy, the damage of the newborn baby would have been avoidable

Pancreatic cancerrelated cachexia: influence on metabolism and correlation to weight loss and pulmonary function

<p>Abstract</p> <p>Background</p> <p>Dramatic weight loss is an often underestimated symptom in pancreatic cancer patients. Cachexia- defined as an unintended loss of stable weight exceeding 10% – is present in up to 80% of patients with cancer of the upper gastrointestinal tract, and has a significant influence on survival. The aim of the study was to show the multiple systemic effects of cachexia in pancreatic cancer patients, in terms of resection rate, effects on pulmonary function, amount of fat and muscle tissue, as well as changes in laboratory parameters.</p> <p>Methods</p> <p>In patients with pancreatic cancer, clinical appearance was documented, including the amount of weight loss. Laboratory parameters and lung-function tests were evaluated, and the thickness of muscle and fat tissue was measured with computed tomography scans. Statistical analysis, including multivariate analysis, was performed using SPSS software. Survival curves were calculated using Kaplan-Meier analysis and the log-rank test. To test for significant differences between the examined groups we used Student's t-test and the Mann-Whitney U test. Significance was defined as p < 0.05.</p> <p>Results</p> <p>Of 198 patients with a ductal adenocarcinoma of the pancreas, 70% were suffering from weight loss when they presented for operation, and in 40% weight loss exceeded 10% of the stable weight. In patients with cachexia, metastases were diagnosed significantly more often (47% vs. 24%, P < 0.001), leading to a significantly reduced resection rate in these patients. Patients with cachexia had significantly reduced fat tissue amounts. Hence, dramatic weight loss in a patient with pancreatic cancer may be a hint of a more progressed or more aggressive tumour.</p> <p>Conclusion</p> <p>Pancreatic cancer patients with cachexia had a higher rate of more progressed tumour stages and a worse nutritional status. Furthermore, patients with cachexia had an impaired lung function and a reduction in fat tissue. Patients with pancreatic cancer and cachexia had significantly reduced survival. If weight loss exceeded 5% there was a significantly reduced resection rate to detect, but the changes were significantly more substantial if weight loss was 10% or more. We propose that a weight loss of 10% be defined as significant in pancreatic cancer.</p

Phase II study of docetaxel and irinotecan combination chemotherapy in metastatic gastric carcinoma

The current treatment for metastatic gastric cancer (MGC) consists of cisplatin and/or fluorouracil (5-FU) based combination chemotherapy, but cisplatin-based regimens are associated with considerable toxicity. We evaluated the efficacy and safety of a noncisplatin-, non-5-FU-containing regimen, docetaxel/irinotecan in MGC. Chemo-naive patients with MGC received docetaxel (30 mg m−2) and irinotecan (70 mg m−2) on days 1 and 8 every 3 weeks. The 48 eligible patients (median age 56 years) received a median of four cycles of docetaxel/irinotecan (range 1–18). Of the 46 patients in whom efficacy could be evaluated, 21 showed a partial response (response rate=45.7%; 95% confidence interval (CI) 31.3–60.1%). At a median follow-up of 15.0 months, the median time to progression was 4.5 months (95% CI 3.8–5.2 months) and overall survival was 8.2 months (95% CI, 5.8–10.6 months). Grade 3/4 neutropenia developed in 57.4% of patients, and febrile neutropenia/neutropenic infection in 19.1%. Nonhaematological toxicities were moderate; grade 3/4 diarrhoea occurred in 19.1% of patients, however, was manageable by a dose reduction. There was one possible treatment-related death. In conclusion, weekly docetaxel/irinotecan is a promising outpatient regimen in MGC, with appropriate dose modification

Phase II study of cetuximab in combination with cisplatin and docetaxel in patients with untreated advanced gastric or gastro-oesophageal junction adenocarcinoma (DOCETUX study)

BACKGROUND: The conventional treatment options for advanced gastric patients remain unsatisfactory in terms of response rate, response duration, toxicity, and overall survival benefit. The purpose of this phase II study was to evaluate the activity and safety of cetuximab combined with cisplatin and docetaxel as a first-line treatment for advanced gastric or gastro-oesophageal junction adenocarcinoma. METHODS: Untreated patients with histologically confirmed advanced gastric or gastro-oesophageal adenocarcinoma received cetuximab at an initial dose of 400 mg m(-2) i.v. followed by weekly doses of 250 mg m(-2), cisplatin 75 mg m(-2) i.v. on day 1, docetaxel 75 mg m(-2) i.v. on day 1, every 3 weeks, for a maximum of 6 cycles, and then cetuximab maintenance treatment was allowed in patients with a complete response, partial response, or stable disease. RESULTS: Seventy-two patients (stomach 81.9% and gastro-oesophageal junction 18.1%; locally advanced disease 4.2%; and metastatic disease 95.8%) were enrolled. The ORR was 41.2% (95% CI, 29.5-52.9). Median time to progression was 5 months (95% CI, 3.7-5.4). Median survival time was 9 months (95% CI, 7-11). The most frequent grades 3-4 toxicity was neutropenia (44.4%). No toxic death was observed. CONCLUSIONS: The addition of cetuximab to the cisplatin/docetaxel regimen improved the ORR of the cisplatin/docetaxel doublet in the first-line treatment of advanced gastric and gastro-oesophageal junction adenocarcinoma, but this combination did not improve the TTP and OS. The toxicity of cisplatin/docetaxel chemotherapy was not affected by the addition of cetuximab
