About locoregional recurrence risk after lipofilling in breast cancer patients: our experience.

AIM: Lipofilling is a part of the clinical practice for breast reshaping in patients who underwent surgery for breast cancer. A strong debate in the Literature is open about a higher risk of cancer relapse caused by growth factors produced by adipocyte stem cells after their engraftment in the recipient tissue. Nowadays there is no agreement over the use of autologous fat tissue for the correction of aesthetic defects following breast conservative surgery. METHODS: We have considered 151 patients who underwent a breast conservative surgery in the period April 2004-April 2009, followed by one or more lipofilling sessions in the period June 2006-August 2012. A careful pre-operative evaluation of the tumor characteristics has been made, through imaging exams, MRI included. An intraoperative evaluation of the tumor dimensions and its distance from the surgical edges has also been made, followed by a microscopic analysis through a shaving technique. Lipofilling has been offered to all the patients on average 24 months after surgery. RESULTS: We have found no cancer relapses after a mean follow up of 45 months (17-76) after lipofilling and of 69 (27-100) months after surgery. CONCLUSIONS: Considering oncologic surgery, we can affirm that lipofilling is safe for the risk of cancer relapses, if performed using all the parameters included in our clinical protocol.

The MRI as a valid help for oncoplastic surgery: esthetic and oncologic results analysis in a group of 489 patients.

AIM: There is an increased expectation from breast cancer patients to retain their "normal breast appearance". To help to achieve this expectation, many radiologic exams have been created to get the exact extension and position of the tumor. MRI is effective to obtain correct information about neoplasms, especially those with shaded edges, like DCIS. MRI might change the surgical project, thus avoiding second operations for cancer relapses. METHODS: We have performed MRI to all the patients except those with big lesions or adypous breasts. We have chosen for reconstruction various oncoplastic techniques. We have had early complications in 98/489 (20%) cases. RESULTS: As late complications, we have found scar retractions and minus areas in 20/489 cases (4.08%), while we have found asymmetries and bigger deformities in 34/489 cases (6.95%). We have not found any cancer relapse after one year, we have had 3 cases of relapse (0.6%) after five years of follow-up, after 5, 4 and 2 years. Our good oncologic and plastic results have to be attributed to many factors, among which stands out the MRI done in all the cases. CONCLUSION: We think that an immediate breast reshaping following quadrantectomy is the best esthetic and psychologic option for breast cancer patients.

The bovine pericardial patch in breast reconstruction: a case report.

In the last years there has been a growing demand of plastic surgery for soft tissue reconstruction. In response to this, many biological and synthetic devices have been produced, aiming to allow wide and complex body reshapings. Acellular dermal matrices are one of these devices, and are made of human or animal tissues made acellular after their sampling. They are used for cervical, breast and abdominal wall reconstruction. Tutopatch®, generally used for face reconstruction or neurosurgery, is made of acellular bovine pericardium, and its high amount of collagen allows a fast tissue healing and a scaffold for the surrounding tissue regeneration. In our case report Tutopatch® has been used in immediate breast reconstruction after mastectomy. This device has been used to close laterally the subpectoral pocket, allowing a bigger volume prosthesis to be placed We have not experienced particular postoperatory complications, and after 12 months of follow up we have found a valid functional and aesthetic result. We consider Tutopatch® as a valid alternative to other acellular dermal matrices specifically designed for breast reconstruction.

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).

Laparoscopic treatment of symptomatic lymphoceles after kidney transplantation.

BACKGROUND: The incidence of lymphocele after kidney transplantation ranges from 0.6% to 18%. This study examines the use of laparoscopic ultrasound for the location of lymphoceles during laparoscopic drainage. METHODS: Between July 1993 and October 1998, we performed 147 kidney transplants. A symptomatic lymphocele was observed in 19 patients (12.9%). All of these patients underwent peritoneal laparoscopic fenestration of the lymphocele. The graft, kidney hilum, ureter, iliac vessels, and lymphoceles were identified by laparoscopic ultrasound. RESULTS: All but one patient were discharged within 24 h. One recurrence (5.2%), which was successfully treated by laparoscopy, was observed at a mean follow-up of 15.5 months. We had one complication (5.2 %)-a left hydrocele that occurred 2 days after drainage of a lymphocele located in the left iliac fossa. CONCLUSIONS: Laparoscopic peritoneal drainage of posttransplant lymphoceles shares the well known advantages of laparoscopy. Furthermore, laparoscopic ultrasound is a useful tool that allows the recognition of anatomical structures and decreases the risk of iatrogenic lesions.

[Benign schwannoma of the celiac tripod simulating a pancreatic neoplasm]. / Schwannoma benigno del tripode celiaco simulante una neoplasia pancreatica.

The authors present a rare case of benign retroperitoneal schwannoma; initially diagnosed as a neoplasm of the pancreas. A comprehensive review of the literature is employed to focus on the main problems involved in the management of this disease: difficulty in formulating a diagnosis, due to the non-specific nature of clinical manifestations; and difficulty in formulating a prognosis, because of the lack of criteria available for distinguishing benign from malignant forms.

[Arterio-portal fistula. Report of a case and review of the literature]. / Fistole artero-portali. Segnalazione di un caso e revisione della letteratura.

Mesenteric arteriovenous fistulas or arterioportal fistulas (APF) are rare and mostly secondary to penetrating abdominal wounds. A rare case of APF presenting 2 years later a blunt abdominal trauma has been reported. On the basis of a review of the literature (65 cases) the etiology, clinical findings, diagnostical aspects and the results of conservative and surgical treatment have been analyzed.

[Medullary carcinoma of the breast. A review of the literature and a report of the authors' own cases]. / Carcinoma midollare della mammella. Revisione della letteratura e presentazione della casistica personale.

Experience with 5 cases of medullary carcinoma of the breast is reported. Reviewing the literature, medullary carcinoma appears to have a better prognosis than infiltrating ductal carcinoma so the proper surgical approach is represented by conservative procedures for lesions < 3 cm with no more than 3 nodes involved. Chemotherapy and radiotherapy don't seem to improve the survival rate.

[Surgical treatment of liver metastases of breast carcinoma. Our experience]. / Trattamento chirurgico delle metastasi epatiche da carcinoma mammario. Nostra esperienza.

The authors report their experience in the surgical treatment of breast cancer liver metastases. Although with a restricted number of cases (4 patients), the short-term results are satisfactory; this is in agreement with the literature. The survival of those patients treated with a loco-regional approach to metastases (chemotherapy and surgery), is longer than one obtained using systemic chemotherapy. This is still an open question requiring further experience.

[Anomalous implantation of the appendiceal base: a clinical case]. / Anomalia di impianto della base appendicolare: caso clinico.

The authors report a case of anomalous implantation of the base of the appendix, observed in a 8-year-old boy, arising from the anterior wall of ascending colon at 15 cm from the ileo-cecal valve. After a brief review of the most frequent congenital anomalies of the appendix and the few cases of anomalous implantation described in international literature, the authors emphasize the importance of an accurate exploration and mobilization of the ascending colon to reduce the risk of diagnostic and therapeutic mistakes, also related to the small incision of McBurney, usually made for the routine laparotomic appendectomy.

[Echolaparoscopy in the staging of abdominal neoplasms. Prospective study]. / L'ecolaparoscopia nella stadiazione delle neoplasie addominali. Studio prospettico.

OBJECTIVE: To evaluate the sensitivity, specificity, positive and negative predictive value and influence on surgical strategy of laparoscopy and laparoscopic ultrasound on staging of abdominal malignancies. MATERIAL AND METHODS: Prospective evaluation of laparoscopic ultrasound staging, according to the TNM classification, of 80 consecutive cases of abdominal malignancies in terms of sensitivity, specificity, positive and negative predictive value and influence on surgical strategy. Pathologic examination of final surgical specimens or laparoscopic biopsies was used as control. RESULTS: Laparoscopic ultrasound evaluation was carried out successfully in 95% of cases with no mortality and morbidity. Twenty one out of 76 patients (28%) had their stage changed based on laparoscopic ultrasound findings. Unnecessary laparotomy was avoided in 11 cases (14%) due to evidence of advanced disease at laparoscopic ultrasound. For pancreatic cancer laparoscopic ultrasound was more sensitive for TNM, specificity was higher just for nodal evaluation. For liver tumor laparoscopic staging revealed more sensitive for N and M evaluation. Laparoscopic ultrasound staging had low specificity and sensitivity for T evaluation, while it was more sensitive and specific than clinical staging for nodal and distant metastasis assessment respectively for gastric and colon cancer. CONCLUSION: Laparoscopic ultrasound staging is a safe, feasible and effective staging tool for several abdominal malignancies. The introduction of laparoscopic ultrasound probes overcomes the lack of tactile sensation proper of laparoscopy, allowing precise evaluation of both solid and deeply located abdominal structures. The use of laparoscopic ultrasound staging may help to reduce the number of unnecessary laparotomies.

[Chemotherapeutic prophylaxis in the preparation of the large intestine for surgical interventions: rifaximin P.O. vs. cephalosporin I.V]. / Profilassi chemioterapica nella preparazione del grosso intestino agli interventi chirurgici: rifaximina P.O. vs. cefalosporina E.V.

30 patients were examined: 17 males and 13 females aged between 53 and 83 years (average age 66 years), candidates for large intestine surgery. For 5 days before the operation, they were treated at random, in a balanced way, with cefotaxime (3 g/day intravenously), either alone or associated with rifaximin (1200 mg/day P.O.). Rifaximin, an antibiotic drug endowed with a topical intestinal action, substantially increased the antibacterial activity of the well known and traditional third-generation cephalosporins therapy in the prevention of bacterial infections after major colic surgery. Intestinal bacterial load and pathogenic micro-organisms reduction was substantially increased. Furthermore, a more limited onset of post- surgical complications was observed, together with a better post-surgical clinical course, and a more rapid recovery of normal intestinal functions. The possibility of carrying out an effective chemoprophylaxis by means of an oral drug, such as rifaximin, must be encouraged as, among other things, it substantially reduces the intolerance risk at systemic level, which is nevertheless possible with parenteral antibiotic treatments.

[Dunbar's syndrome: clinical reality or physiopathologic hypothesis?]. / Sindrome di Dunbar: realtà clinica o ipotesi fisiopatologica?

The authors report the cases of two patients presenting a symptomatic intestinal angina caused by median arcuate ligament compression. Arteriography demonstrates severe coeliac artery stenosis in both of them and a retrograde filling of the coeliac axis from the superior mesenteric artery branch collateral vessels. The patients became asymptomatic after surgical release of the celiac trunk by section of the median arcuate ligament of the diaphragm. At 2 and 3 years follow-up, both patients report no further abdominal pain. Dunbar's syndrome is still a questionable subject; how can be a narrowing or an occlusion of the celiac artery semeiotically and clinically important? Some have proposed an ischemic base to explain the abdominal pain: the compression of the celiac trunk could be responsible of a celiac steal which results in shunting of blood from the superior mesenteric artery to the celiac distribution through the collateral system. There are very strong proofs that partial or even complete obstruction of the celiac artery should not lead to visceral ischemia such as: the rich collateral anastomosis of the celiac axis, the surgical ligation of the celiac axis performed without untoward consequences, the finding of asymptomatic celiac stenosis in the 49% of an arteriographic study, impossibility to formulate a consistent and rational for the surgical results. Shearing this view, few authors would prove that a stenotic type of the celiac artery is only a normal anatomic variant, refuting the existence of this syndrome.

Oncoplastic surgery and cancer relapses: cosmetic and oncological results in 489 patients.

During the past 20 years, breast conservation has become the preferred treatment modality for breast carcinoma, and in recent times there is an increased expectation from breast cancer patients to retain their "normal breast appearance". For large tumor-to-breast ratio excision, the subspecialty of oncoplastic surgery is born, helping to achieve a good oncologic and esthetic result. In our study we have considered 767 patients undergone a mastectomy or quadrantectomy, and especially 489 undergone quadrantectomy. We have used our protocol for breast reshaping and analyzed our data in terms of oncologic safety and esthetic results. Considering the lesions, they were placed like this: 214 (44%) in the SEQ, 58 lesions (12%) in the SIQ, 54 lesions (11%) in the IEQ, 24 lesions (5%) in the IIQ, 45 lesions (9%) respectively in the CQ and between the SQ, 39 lesions (8%) between the EQ, 5 lesions (1%) respectively between the internal quadrants and between the inferior quadrants. We have chosen simple breast reshapings in case of operations on the superior quadrants, while, in case of operations on the inferior quadrants, we have chosen complex techniques, like reshapings according to a "key hole" reductive mammaplasty, which requires also a contralateral reshaping. We have done simple and monolateral reshapings respectively in 372 (76%) and 296 (60.5%) cases. We have had early complications in 98 (20%) cases: 12 infections (2.4%), 10 hematomas (2%), 11 seromas (2.2%), 65 liponecrosis. As late complications, we have found scar retractions and minus areas in 20 cases (4.08%), while we have found asymmetries and bigger deformities in 34 cases (6.95%). We have not found any cancer relapse after one year of follow up, while we have had 3 cases of relapse (0.6%) after 5 years of follow up, respectively after 5, 4 and 2 years. This result has to be attributed to our preoperatory project of surgery derived from many factors, among which stands out the MRI done in all the cases. We think that an immediate breast reshaping following quadrantectomy is the best esthetic and psychologic option for breast cancer patients.

Preoperative chemoradiotherapy in cancer of the thoracic esophagus.

Surgery with or without adjuvant radiotherapy (RT) is the standard treatment of esophageal cancer. Preoperative radio- and chemotherapy (CT) have been introduced to improve prognosis. We report a phase II prospective non-randomized trial of preoperative RT (42 Gy/25) plus CT (cisplatin 20 mg/mq/day plus 5-fluorouracil 600 mg/mq/day, 1-5 weeks) for the treatment of thoracic esophageal cancer. From 1993, 50 patients were enrolled (40 men and 10 women, mean age 57 years, range 30-75 years). Squamous cell carcinoma accounted for 90% of cases; 10% were adenocarcinoma. Downstaging of the disease was obtained in 77.3% of cases; there were 13 (29.5%) complete responses (CR) and 21 (47.7%) partial responses (PR). Median survival was 28 and 25 months, respectively, for CR and partial response (PR) plus stable disease (SD) and progressive disease (PD) (P = 0.05). Progressive-free median survival was 22 and 17 months, respectively, for CR and PR + SD + PD (P = 0.08). Multimodal treatment of esophageal cancer showed promising results, although not significant, in terms of survival and disease progression for patients achieving a complete pathologic response.
