Pseudomembranous colitis associated with chemotherapy with 5-fluorouracil

Pseudomembranous colitis is frequently associated with antibiotics and more rarely with chemotherapeutic agents such as 5-fluorouracil. The objective of this study is to show that it is possible to confuse this infection with chemotherapy associated toxicity. We present a 54 year old woman who underwent surgery for colorectal cancer and in the first cycle of chemotherapy with 5-fluorouracil developed pseudomembranous colitis. We detected the toxin B ofClostridium difficile in stools and we began early antibiotic treatment. Thus, in patients with post chemotherapy neutropenia and diarrhoea that develop negatively, we have to rule out this infection.

Adjuvant treatment in elderly patients with breast cancer: critical review of clinical practice.

Today the use of adjuvant treatment of breast cancer is unquestionable in the management of this disease. Both chemotherapy and hormonal therapy have proved to be beneficial, not only with respect to the reduction of the risk of recurrence, but also with respect to mortality. However, in elderly patients, this therapeutic approach is occasionally the subject of controversy, due to the undervaluing of the tumoral disease with respect to the multiple pathology frequently present in these patients. This study analyses a retrospective series of 100 patients more than 70 years old with breast cancer who underwent radical surgery between 1990 and 1998, with an extension study without evidence of metastasis and a minimum follow-up of 2 years. As occurs in the population of this age, in our series 77% of the patients presented with concomitant disease under medical treatment, and although the majority received adjuvant treatment with tamoxifen, the principal cause of death in this series was the breast cancer that had been diagnosed.Today the use of adjuvant treatment of breast cancer is unquestionable in the management of this disease.

Breast cancer screening: another point of view

The breast cancer screening programmes (BCSP) are very controversial at the present time. They are evaluated by different socio-economic sectors, each with its own particular point of view. Large numbers of breast cancer cases are concentrated in the Oncology Services, which are, therefore, sensitive to the changes that these programmes could bring about. All patients attending the medical oncology and radiotherapy services of the Reina Sofia University Hospital, Córdoba from January 1994 until January 2003 were reviewed. Of 1785 patients, 829 went to these services after the start of the BCSP introduced in March 1999 and 956 before it. The variables analysed were age, presentation form, stage and treatment received. In conclusion, the BCSP has produced favourable changes with respect to stage (increasing the percentage of early breast cancer) and therapeutic management (increasing conservative surgery and decreasing the number of adjuvant treatments (radiotherapy and chemotherapy)). These changes are more outstanding in the population group covered by the BCSP.

Reactivación del virus de la hepatitis B en paciente oncológico tras tratamiento con quimioterapia: hepatitis fulminante

Re-activation of the hepatitis B virus is very unusual, but has been described as a complication of chemotherapy. Most reported cases are related to haematological malignancies and, occasionally, to solid tumours.We report a case of hepatitis B virus re-activation resulting in fulminant hepatitis in a patient with non-small-cell lung cancer following chemotherapy with cisplatin and gemcitabine.Risk-factors associated with the re-activation were gender, age and the administration of cortico-steroids.During chemotherapy administered to patients with a history of chronic hepatitis B, care must be taken to avoid the administration of cortico-steroids as anti-emetics, and to monitor the patients transaminase concentrations.
