EBV positive primary cutaneous CD30+ large T-cell lymphoma in a heart transplanted patient: case report.

Most post-transplant lymphoproliferative disorders (PTLDs) are of B-cell origin, whereas T-cell lymphomas rarely occur. We detail the clinicopathological features of the first case of Epstein-Barr virus (EBV)-associated primary cutaneous CD30+ anaplastic large cell lymphoma (ALCL) in the setting of heart transplant. A 71-year-old patient, 111 months after transplant, presented with multiple cutaneous lesions on the left thigh; histological and immunohistochemical examinations led to diagnosis of T-cell CD30+ ALCL. In situ hybridization demonstrated the presence of EBV-positive tumour cells. The patient received radiotherapy, but he relapsed at the same cutaneous site with loco-regional nodal spread. Chemotherapy was administered resulting in complete remission; four years later the patient is alive and well. Our findings indicate that primary cutaneous EBV+ CD30+ ALCLs should be included within the T-cell PTLDs spectrum; further studies are required to confirm whether they may be also considered, in transplantation settings, a distinct lymphoma subset with relatively favourable outcome.

Are international guidelines for the prescription of adjuvant treatment for early breast cancer followed in clinical practice? Results of a population-based study on 1547 patients.

AIMS AND BACKGROUND: The results of several randomized trials and meta-analyses have been reported on adjuvant treatment for early breast cancer and treatment guidelines have been defined accordingly, but detailed data are lacking on the appropriateness of treatment prescription in clinical practice. METHODS: We performed a prospective, observational, multicenter study to monitor the prescription, delivery and effectiveness of radiotherapy following conservative surgery for early breast cancer; 1610 patients treated with postoperative radiation to the breast in 1997 were entered by 12 centers in Lombardy, Italy. Here we report the results of a secondary analysis focused on the prescription of medical adjuvant treatment (1547 eligible patients). RESULTS: Chemotherapy only was prescribed to 526 patients (33%), hormonal therapy only to 539 (33%), and both treatments to 85 patients (5%); 460 women (29%) received no medical adjuvant treatment. We compared the collected data with guidelines defined in 1995 by the St Gallen Consensus Conference. Undertreatment was most frequent in node-negative patients at intermediate/high risk, no treatment (instead of tamoxifen or chemotherapy) being prescribed in 21-45% of cases. Node-negative patients at low risk, on the other hand, were overtreated with tamoxifen in 31% of cases. In node-positive, premenopausal women compliance with guidelines was far better, with a 91-96% rate of chemotherapy prescription. In node-positive, postmenopausal, estrogen receptor-positive patients chemotherapy was unduly prescribed in as many as 56% of cases. Comparison of clinical practice with the next version of the guidelines (1998) showed a somewhat better compliance. CONCLUSIONS: Despite the availability of official and authoritative guidelines, adjuvant treatment prescription for early breast cancer in Lombardy in 1997 was suboptimal, especially in well-defined subgroups of patients.
