The survival time in a group of eight bitches with malignant mammary tumours given adjuvant post-operative chemotherapy was compared with survival in another group of eight bitches with mammary cancer which were treated by surgical excision alone. The same surgical procedure was used in both groups. All bitches had stage III disease according to the World Health Organization clinical staging system. Histologically, 10 of the bitches had complex carcinomas (carcinomatous mixed tumours), the remaining six bitches had carcinosarcomas. The chemotherapeutic protocol used was a combination of 5-fluorouracil (150 mg/m2 of body surface area) and cyclophosphamide (100 mg/m2) given on the same day, intravenously, every week for four consecutive weeks. Chemotherapy was started one week post-surgery. Selected haematological parameters (packed cell volume, white blood cell count, platelet count and differential white blood cell count) and serum biochemical parameters (alanine aminotransferase, alkaline phosphatase, blood urea nitrogen and creatinine) were measured before and during chemotherapy. Survival analysis indicated that the chemotherapeutic regimen had a positive influence on the disease-free interval and the survival time of the eight bitches (P < 0.05). Although leucocyte numbers were significantly decreased (P < 0.001) during chemotherapy, the mean leucocyte counts remained within normal limits. Temporary leukopenia was noted only in one bitch. Packed cell volume and alkaline phosphatase increased significantly (P < 0.05) but within normal limits. Creatinine was also increased significantly (P < 0.01) but the mean creatinine concentrations were within normal limits, although in half of the bitches the concentrations occasionally rose above normal.

Serial determination of serum ALP activity during fracture healing could be an additional tool in predicting fractures at risk of developing a nonunion, helping the clinician to choose the appropriate intervention.

The expansion of chemotherapy raised concerns about the health and safety of hospital personnel. Very little is known about the conditions of handling of chemotherapeutic agents by healthcare workers in Greece and possible adverse effects related to their safety practices, as well as the safety policies adopted by the Greek hospitals. A self-evaluation questionnaire was completed by 353 healthcare workers involved with the use of chemotherapeutic drugs in 24 Greek hospitals and the answers were statistically analysed. The majority of the healthcare workers are aware of the dangers of their work, although they had received limited training and medical surveillance. A significant percentage of them does not use personal protective equipment or use it inadequately. The safety design of their workplace is rather poor. Different health problems have been experienced, deriving from the respiratory, central nervous system, reproductive, gastrointestinal and musculoskeletal system. The improvement of safety training and procedures as well as medical surveillance seems to be a vital priority of hospital administration in Greece, in order to comply with the European guidelines and for the prevention of occupational diseases and environmental pollution.
