Radiotherapy of relapse-refractory follicular lymphoma.

PURPOSE: To assess the efficacy of treatment and outcomes of patients with relapsed or refractory follicular lymphoma treated with external beam irradiation. PATIENTS AND METHODS: Fifteen patients who received external beam radiotherapy for relapsed or refractory follicular lymphoma were studied. The median age was 68.3 years (range: 37.9-87.08 years) with four men and 11 women. Seven patients had early stage (I or II); eight advanced stage (III or IV). Median FLIPI score was 2. Two patients had high tumour bulk disease. Six patients had extranodal invasion, with five patients having bone marrow invasion. RESULTS: The median time of follow-up after relapse or first-line treatment in case of refractory disease was 61.9 months (range: 9.1-119.7 months). Complete response after external beam radiotherapy was seen in 11 cases (73%) and partial response in two (13%), with a median dose of 30Gy (range: 2-40Gy) and median number of fractions of 15 (range: 2-20). Eight patients (53%) relapsed after external beam radiation therapy in a median of 20.2 months, mostly out of irradiated volumes. Most patients (66%) had a disease control after one or two courses of external beam radiation therapy. At last follow-up, 86% of patients were in remission including those with salvage chemotherapy. The toxicity profile was favourable with toxicity higher than grade 1. In univariate analysis, a Follicular Lymphoma International Prognostic Index (FLIPI) score above 2 was the only predicting factor for non-control disease. CONCLUSION: For relapsed and refractory follicular lymphoma, external beam radiotherapy should be considered as an effective modality when integrated in a multimodality approach. Randomised studies are warranted to validate this strategy.

Recurrence of giant juvenile breast fibroadenoma in a girl with Turner's syndrome.

Pathological breast conditions are rare in childhood and adolescence. The spectrum of breast disease in pediatric patients is different from that in adults and most lesions are benign. Fibroadenomas are the most common type of breast tumor in adolescent girls and young women. These lesions occasionally develop into very large masses, particularly in adolescent girls. Such masses are called solitary giant juvenile fibroadenomas, and local recurrence is unusual. We report here a case of recurrent juvenile giant breast fibroadenoma in a girl with Turner's syndrome.

[Experimental kidney transplantation: a comparison between different models]. / Trapianto di rene sperimentale nel suino. Modelli a confronto.

AIM: Two different models of kidney transplantation have been compared using 3 different techniques. The kidney grafts were procured from living donors (laparoscopic or laparotomic technique) and from cadaveric donors. METHODS: Twenty-four outbred piglets (Large White, weight range 24-27 kg) underwent kidney transplantation. We divided the recipients into 2 groups with the following characteristics: group 1 (n=12) was represented by orthopic kidney recipients whose grafts were retrieved by laparoscopic or lapartomic technique from living unrelated donors; group 2 (n=12) was constituted by heterotopic kidney recipients whose grafts were retrieved by laparotomic technique from unrelated cadaveric donors. In both groups, Grogoire-Lich technique and Politano-Laedbetter technique were used in order to perform ureteral-vescical anastomosis together with a new technique developed from our experience called Politano-Laedbetter modified. All transplanted pigs underwent double immunosoppressive steroid therapy (tacrolimus and micofenolate mofetil). The pigs were observed for 60 days. RESULTS: The survival rates in group 1 and in group 2 were 75% (n=9) and 66% (n=8), respectively. No significative differences were noted in length of operative time, creatinemia and ureamia levels in both study groups. The Gregoire-Lich technique was associated with a higher rate of complications. CONCLUSION: Two different experimental models of kidney transplantation are feasible in pigs. The classic technique could be combined with the orthopic one based on the type of study needed.
