RESUMEN
BACKGROUND: The aim of this study is to compare the clinical course of idiopathic granulomatous mastitis (IGM) treated with low-dose oral corticosteroid therapy alone as opposed to treatment with low-dose corticosteroid therapy followed by surgery. PATIENTS AND METHODS: 37 patients were treated with an approach that consisted of methylprednisolone at a dose of 0.5 mg/kg/day followed by wide excision, and 23 patients were treated with an approach that consisted only of methylprednisolone. The treatment efficacy was compared between the two groups. RESULTS: Clinical and radiological regression was reported in all patients with steroid therapy, and the regression rate had a median of 75% (25-100%). No recurrence was observed in patients who were treated with wide surgical excision after steroid therapy during the median follow-up period of 38 (22-78) months. The control group of 23 patients was treated only with steroid therapy, and 7 (30%) of these patients experienced recurrence in the follow-up period (p < 0.001). CONCLUSIONS: Steroid therapy was effective in the treatment of IGM by reducing the lesion size and extent. With regard to the current treatment options available for IGM, surgical excision after steroid therapy seems the better treatment option compared to steroid therapy without surgical excision. This treatment sequence reduces the rate of recurrence.
RESUMEN
Intraoperative radiation therapy in breast cancer (IORT) delivers a concentrated dose of radiation therapy to a tumor bed during surgery. IORT offers some of the following advantages with typically fewer complications like; maximum effect, sparing healthy tissues and organs, to help the patients finish treatment and get back to their normal activities. The goal of IORT is to improve local tumor control and survival rates for patients with breast cancer. IORT can both be performed with electron beams (ELIOT) and X-rays. Two main randomised trials testing intraoperative partial breast radiotherapy are TARGIT trial and the ELIOT (intraoperative radiotherapy with electrons) trial, but the techniques are fundamentally different. Whereas TARGIT delivers radiation from within the undisturbed tumour bed, for ELIOT, the mammary gland is mobilised, a prepectoral lead shield is inserted, the edges of the tumour bed are apposed, and radiation is delivered from without.
RESUMEN
OBJECTIVE: The aim of the study is to investigate the effectiveness of the controlled slow-release granulocyte-monocyte colony-stimulating factor (GM-CSF) system in burn wound healing. MATERIAL AND METHODS: In vivo effect of controlled slow-release GM-CSF from chitosan gel on burn wound healing was evaluated on 18 Wistar-Albino rats, weighing between 250 and 300 g. They were randomly divided into 3 groups; (1) burned only group (n = 6), (2) burned + chitosan group (n = 6), (3) burned + chitosan + GM-CSF group (n = 6). Wound area was measured macroscopically. Hematoxylin and eosin and Masson's trichrome stained sections were evaluated for wound healing and tissue response to the polymer. RESULTS: The best healing process was observed with the controlled slow-release GM-CSF-applied group (group 3) in which the wound area was significantly narrowed. CONCLUSION: The study demonstrated the positive contribution of the single-dose controlled slow-release GM-CSF from chitosan gel on burn wound healing.

PURPOSE: Atherosclerosis observations after splenectomy for trauma and hypersplenism suggests a possible role for the spleen in lipid metabolism. The authors examined the effects of splenectomy on serum lipids in rats and also cholesterol-fed rats with experimental atherosclerosis. METHODS: This study was designed on rats. The rats were divided into five groups: splenectomy, normal diet (SP-N, n: 8), splenectomy, cholesterol-fed groups (SP-C, n: 8), splenic autotransplantation after splenectomy, normal diet (SA-N, n: 8), splenic autotransplantation after splenectomy, cholesterol-fed groups (SA-C, n: 8) and sham groups (n: 8). Total triglyceride, total cholesterol, HDL (high-density lipoprotein), LDL (low-density lipoprotein), and VLDL (very low-density lipoprotein) levels were determined in 40 rats. The rats were classified into five groups based on the surgical procedures. The spleens were removed and then the rats were fed a normal diet in Group SP-N (n = 8). The spleens were removed and then the rats were fed a diet containing 1% cholesterol in Group SP-C (n = 8). Splenectomy and splenic autotransplantations were performed and then the rats were fed a normal diet in Group SA-N (n = 8). Splenectomy and splenic autotransplantations were performed and then the rats were fed a diet containing 1% cholesterol in Group SA-C (n = 8). The rats were sham-operated in the control group (Group S, n = 8). An active splenic function was shown in rats that underwent splenic autotransplantation in both groups by using Technicium 99 m sulphurcolloide sintiscan on day 30. Blood lipid levels were repeated 6 months later. RESULTS: There was no difference between pre- and postoperative lipid levels in the sham group and SA-N group (p >.05). All lipid levels including HDL were increased significantly in SP-C group (p <.05). Also VLDL and total tryglyceride levels were increased significantly in SP-N and SA-C groups (p <.05). CONCLUSIONS: This study showed that the spleen might have an important effect on lipid metabolism and splenic autotransplantation may be protective in conditions with increased lipid levels.

BACKGROUND: Previous studies show that local recurrences after breast-conserving treatment occur in the site of the primary tumor. The need for postoperative radiotherapy on the whole breast is challenged in favor of radiotherapy limited to the area of the breast at high risk of recurrence. The new mobile linear accelerators easily moved close to the operating table to allow the full-dose irradiation during surgery. PATIENTS AND METHODS: From July 1999 to December 2003, 590 patients affected by unifocal breast carcinoma up to a diameter of 2.5 cm received wide resection of the breast followed by intraoperative radiotherapy with electrons (ELIOT). Most patients received 21 Gy intraoperatively, biologically equivalent to 58 to 60 Gy in standard fractionation. Patients were evaluated 1, 3, 6, and 12 months after surgery, and thereafter every 6 months, to look for early, intermediate, late complications, and other events. RESULTS: After a follow-up from 4 to 57 months (mean, 24 months; median, 20 months), 19 patients (3.2%) developed breast fibrosis, mild in 18, severe in 1, which resolved within 24 months. Three patients (0.5%) developed local recurrences, 3 patients ipsilateral carcinomas in other quadrants and other 5 patients contralateral breast carcinoma. One patient (0.2%) died of distant metastases. CONCLUSIONS: ELIOT is a safe method for treating conservatively operated breasts, avoids the long period of postoperative radiotherapy, and reduces drastically the cost of radiotherapy. ELIOT reduces radiation to normal tissues and organs. Results on short-term and middle-term toxicity up to 5 years of follow-up are good. Data on local control are encouraging.

Breast hamartoma is an uncommon benign lesion, composed of varying amounts of fatty, fibrous and glandular elements. It can present as a breast mass and therefore additional care needs to be taken to rule it out in the differential diagnosis of breast carcinoma. We report a case of a breast hamartoma treated at the European Institute of Oncology.

We present our experience of 50 cases of occult primary tumours presenting as axillary metastases, all with histological report of adenocarcinoma compatible with mammary carcinoma. After bilateral US and mammography, with MRI and mammoscintigraphy where necessary, ipsilateral breast cancer was suspected in 23 cases and quadrantectomy performed. Breast cancer was found only in 12 (24%). In the other 27 women there was no clinical or instrumental suspicion of breast cancer or other primary disease site, so the main treatment was complete axillary dissection plus radiotherapy to the ipsilateral breast (given to all patients). Chemotherapy alone was given to 27 patients, hormone treatment to 5 patients, and both to 18. Mean follow-up is 41.3 months (range 108-1). Thirty-nine (84%) patients are alive with no evidence of disease, two are alive with breast disease, five patients have died of metastatic disease (with no evidence breast disease). Our experience, like that of the literature, confirms that the breast should be extensively investigated but that blanket investigations are not usually revealing. We present guidelines for the work-up of patients presenting with axillary disease.

AIMS AND BACKGROUND: Adenomyoepithelioma is a rare lesion that can involve the breast tissue. The diagnostic appearance of the lesion can give rise to a difficult differential diagnosis with breast carcinoma. PATIENTS AND METHODS: We report our experience with a case of adenomyoepithelioma whose differential diagnosis with a breast carcinoma was particularly difficult, leading to surgery for definitive histology. DISCUSSION: Few papers are available with evidence about adenomyoepithelioma. The difficult differential diagnosis and the potentiality of malignant evolution of this lesion could in principle justify a conservative surgical approach for final histology.
