Secondary breast angiosarcoma: A multicentre retrospective survey by the national Italian association of Breast Surgeons (ANISC).

BACKGROUND: Breast angiosarcoma is a malignant mesenchymal neoplasm, which accounts for approximately 2% of all soft tissue sarcomas. Secondary breast angiosarcoma (SBA) may be related to chronic lymphedema after a mastectomy with lymph node dissection (Stewart Treves syndrome) and previous radiotherapy for complications from breast radiation treatment. It is a very rare condition; therefore, diagnosis and management are still a challenge. METHODS: The ANISC collected SBA data by means of a survey sent to all Italian breast centres in the ANISC. The clinicopathological characteristics and the management of this disease were analysed. RESULTS: Twenty-four centres participated in this survey in which 112 cases of SBA were analysed. The median age of the women with SBA was 68.9 years and it appeared approximately 90 months after the first irradiation for breast cancer. In 92% of cases, a mastectomy was performed without axillary dissection for those patients having a high grade of SBA (74.2%). The prognosis was worse in the high-grade cases (overall survival-OS: 36 months) as compared with the low-grade cases (OS: 48 months). After a follow-up of 5 years, 50.5% of the patients were still alive. Disease-free survival (DFS) was 35 months, and there were no differences between the groups of patients with either high- or low-grade histology. CONCLUSIONS: Secondary breast angiosarcoma is a very aggressive disease associated with a short survival outcome. The surgical approach still remains an important step in the course of treatment; furthermore, an accurate histological examination is helpful in establishing the prognosis of the patient. A mastectomy is mandatory. A longer OS was observed in patients with low-grade angiosarcoma as compared to high-grade angiosarcoma (C.I. 40-57 vs. 31-41 months).

Electrochemotherapy in the Treatment of Cutaneous Metastases from Breast Cancer: A Multicenter Cohort Analysis.

BACKGROUND: The management of breast cancer (BC) skin metastases represents a therapeutic challenge. Electrochemotherapy (ECT) combines the administration of bleomycin with temporary permeabilization induced by locally administered electric pulses. Preliminary experience with ECT in BC patients is encouraging. METHODS: A total of 125 patients with BC skin metastases who underwent ECT between 2010 and 2013 were enrolled onto a multicenter retrospective cohort study. The treatment was administered following the European Standard Operative Procedures of Electrochemotherapy. Tumor response was clinically assessed adapting the Response Evaluation Criteria in Solid Tumors, and toxicity was evaluated according to Common Terminology Criteria for Adverse Events 4.0. Cox regression analysis was used to identify predictive factors. RESULTS: Response was evaluable in 113 patients for 214 tumors (median 1 per patient, range 1-3). The overall response rate after 2 months was 90.2 %, while the complete response (CR) rate was 58.4 %. In multivariate analysis, small tumor size (P < 0.001), absence of visceral metastases (P = 0.001), estrogen receptor positivity (P = 0.016), and low Ki-67 index (P = 0.024) were significantly associated with CR. In the first 48 h, 10.4 % of patients reported severe skin pain. Dermatologic toxicity included grade 3 skin ulceration (8.0 %) and grade 2 skin hyperpigmentation (8.8 %). Tumor 1-year local progression-free survival was 86.2 % (95 % confidence interval 79.3-93.8) and 96.4 % (95 % confidence interval 91.6-100) in the subgroup of those with CR. CONCLUSIONS: In this study, small tumor size, absence of visceral metastases, estrogen receptor positivity, and low Ki-67 index were predictors of CR after ECT. Patients who experienced CR had durable local control. ECT represents a valuable skin-directed therapy for selected patients with BC.

[Radiofrequency wave treatment of liver tumors]. / Il trattamento con onde a radiofrequenza dei tumori epatici.

The surgical therapy modifies the survival of the patients affections from tumor of the liver, primitive or secondary. The concomitance of cirrhosis, the dimensions, center and the distribution of the tumor reduces notably the number of the patients that they could be subjected to resection. The authors expose their experience with the employment of the radiofrequency thermoablation in the cases not tractable by means of surgery.

[Granular cell tumor of the male breast. A case report]. / Il tumore a cellule granulari della mammella maschile. Descrizione di un caso clinico.

Granular cell tumor of the male breast is an extremely rare neoplasm. The case of a 64-year-old man with a periareolar lump in the upper medial quadrant of his left breast of recent onset is reported. At clinical examination, it was a poorly circumscribed, irregular, hard, mobile 1 cm mass. No axillary lymph nodes were palpable. The patient was submitted to ultrasound scan which showed a 1 cm periareolar solid hypoechoic lesion with an acoustic shadowing and subsequently to fine needle biopsy that revealed the presence of also atypical ductal hyperplasia. For this reason he was submitted to excision biopsy. The definitive histology was of granular cell tumor. The immunohistochemical investigations showed an intense positiveness for S-100 protein; the staining with PAS showed a diffuse positiveness. At 18 months after treatment the patient had no recurrence of disease. Granular cell tumor of the male breast is a neoplasm whose differential diagnosis with carcinoma is often possible only with definitive histology. For this reason, also in front of a mammary lump strongly suspicious for carcinoma, it's always necessary to think it can be this neoplasm and therefore to wait for the necessary histopathologic confirmation.

[Subcutaneous peduncle flaps in reconstructive surgery]. / I lembi a peduncolo sottocutaneo in chirurgia ricostruttiva.

Among the varying forms of cutaneous flaps, V-Y flaps are finding an increasingly wide application in reconstructive surgery. Their use has been extended, depending on the cutaneous area in question, to various sizes of loss of substance. According to the type of tissues involved, the peduncle may be adipose, fascial or muscular. Vascularisation is random, but in those cases in which the base consists of muscle fascia an axial type is used since the peduncle generally corresponds to a well-known artery. V-Y flaps can repair defects measuring upto 5 cm in diameter and also guarantee a rotation of upto 90 degrees. The authors report their experience of 134 cases in which V-Y flaps were used in the reconstruction of loss of substance localised on the face, upper limbs, trunk, gluteal region, ear, leg and foot. The underlying pathologies consisted mainly of skin cancers, loss of substance following injury, scar retractions, syndactylia, decubitus ulcers in the gluteal region and a trophic foot ulcer. It was not necessary to re-operate any patient owing to problems linked to retraction or the unsightly appearance of residual scars. In the past V-Y flaps were indicated above all for the reconstruction of loss of face substance, but their use today has been extended to other districts. The authors highlight the advantages offered by V-Y flaps: ease and rapidity of use, the characteristics of the skin graft are identical to that removed, and the preservation of sensitivity.

[Angioma in childhood: current criteria for therapy]. / Angiomi dell'infanzia: attuali criteri di terapia.

After examining the most recent literature on this subject, the authors assess the state of the art of current knowledge regarding cutaneous angioma in the light of their personal experience. The histological, biological and clinical characteristics are analysed and enable a new nosographic evaluation of this frequent pathology which must be differentiated from vascular malformations. In the light of these unique features, the authors examine the current forms of treatment for angioma using local, systemic or physical therapy. Cutaneous angioma may be present at birth or may appear during the first months of life, occasionally regressing spontaneously up until the child is seven years old. They also present a population of proliferating endothelial cells. This explains the possibility that these neoformations will spontaneously regress, an event that must be taken into account before commercing therapy. With regard to their diagnosis valuable information is provided by telethermography, ultrasonography, Doppler scan and CAT. If an angioma is present from the first weeks of life, a wait-and-see policy should be adopted unless the lesion is localised in an orbital, mammary, palpebral, subglottic, nasal or labial region. Local therapy of angioma using sclerosant substances is now controversial; the best results are obtained using periodical administrations of triamcinolone acetonide or betamethasone. Systemic treatment with prednisone is indicated in forms localised on the orbita where interlesional injections are frequently followed by complications such as hematoma and infections. Systemic treatment requires an interdisciplinary approach, especially in pediatrics, due to the repercussions which the use of high dose conrticosteroids provokes on hormone function in children. The use of alpha interferon with discordant results has recently been reported in the literature. In superficial forms physical therapy may be more appropriate. Cryotherapy provoked a lesion caused by cold: an ionic alteration of tissues through freezing leads to necrosis. Plesiotherapy has been now virtually abandoned due to the risks of growing tissue. In terms of therapy and application there has been a widespread increase in the use of argon laser over the past years: the "Tunable Dye Laser" present unique characteristics which allow the wave length to be modulated in relation to the colour and depth of the lesion to be treated, causing selective photothermolysis. Encouraging results can be obtained by subjecting immature angioma to applications every 3-4 weeks using an every of 7-8 J/cm2. The use of the tunable dye laser is, however, preferable in superficial angioma. Compressive therapy using elastic bandages or specially made garments is effective only in those localisation where it is possible to obtain compression, like limbs and the parotid region. From the above comments it can be seen that the treatment of immature angioma is extremely complex due to their clinical and evolutive variability. It is therefore vital to following the rules laid down by experience: waiting for the involution of the angioma, even if it is commonly observed event, is often difficult to achieve due to the scarce collaboration of parents. Moreover, it is important to achieve a close interdisciplinary collaboration between pediatrician, dermatologist and plastic surgeon.

[Intraoperative ultrasonography in the diagnosis of liver metastasis from gastrointestinal neoplasms]. / L'ecografia intraoperatoria nella diagnosi di metastasi epatiche da neoplasia gastrointestinale.

The authors illustrate their experience in the systematic use of intraoperative ultrasonography of the liver in patients undergoing surgery due to gastrointestinal cancer. The liver is the organ in which metastases from colorectal, stomach, pancreatic, and biliary cancer are most often localised. Between January 1991 and April 1992 95 patients underwent intraoperative ultrasonographic controls of the liver. In all cases the liver was studied using traditional image diagnosis: standard ultrasonography and CAT. On the basis of their experience the authors observed 12 cases negative for metastases using CAT and traditional ultrasonography which were positive using intraoperative ultrasonography, 2 cases which were positive for secondary hepatic lesions using traditional diagnostic tools but negative following histological tests guided by intraoperative ultrasonography. In the case of false negatives using traditional methods, those metastases revealed by intraoperative ultrasonography were above all located deep down and in segments which are difficult to explore, or were so small that they were not visible or palpable during intraoperative controls of the viscera. Intraoperative ultrasonography of the liver has been found to be a more sensitive test (97% of the best series) than standard ultrasonography (65%) or CAT (43%). Higher resolution due to the characteristics of the method is coupled with the possibility that intraoperative ultrasonography may be used to guide biopsies of the metastases revealed, thus allowing histological confirmation to be obtained: for this reason the risk of false positives is virtually zero.(ABSTRACT TRUNCATED AT 250 WORDS)

[Acute abdomen in patients with hematologic neoplasms]. / L'addome acuto nei pazienti con neoplasie ematologiche.

Sixteen onco-haematological patients with acute abdomen are presented. The diagnosis of acute abdominal conditions was: neutropenic enterocolitis, gastrointestinal perforation, bowel neoplastic obstruction hepatic abscess and strangulated tumoral hernia. The operative death was 31.2%; 62.5% died 2-24 months after surgery and 6.3% is alive at 72 months. The Authors conclude that in these patients the extended surgery should be performed only in prognostic all favourable cases.
