Use of Axillary Ultrasound, Ultrasound-Fine Needle Aspiration Biopsy and Magnetic Resonance Imaging in the Preoperative Triage of Breast Cancer Patients Considered for Sentinel Node Biopsy

We assessed the diagnostic yield of axillary ultrasound, alone or in combination with fine-needle aspiration axillary biopsy and magnetic resonance imaging in patients with invasive breast carcinoma compared with final axillary histology by sentinel node biopsy or by axillary lymph node dissection. From January 2003 to March 2009, 520 axillary ultrasound examinations and 105 axillary magnetic resonance imaging studies were included. Compared with final axillary histology, ultrasound fine-needle aspiration showed positive predictive value of 87%, negative predictive value of 82%, sensitivity of 53% and specificity of 100%. In cases of negative ultrasound, the rate of positive nodes was 17% (micro-metastases excluded). Ultrasound examination of the axilla, combined with fine-needle aspiration as appropriate must be included in the preoperative work-up of patients considered for sentinel node biopsy to definitively establish such an indication while minimizing the risk of false-negative sentinel node. Axillary magnetic resonance imaging did not improve the preoperative work-up.

Adrenalectomy for solid tumor metastases: Results of a multicenter European study

BACKGROUND We assessed the results of adrenalectomy for solid tumor metastases in 317 patients recruited from 30 European centers. METHODS Patients with histologically proven adrenal metastatic disease and undergoing complete removal(s) of the affected gland(s) were eligible. RESULTS Non-small cell lung cancer (NSCLC) was the most frequent tumor type followed by colorectal and renal cell carcinoma. Adrenal metastases were synchronous (≤6 months) in 73 (23%) patients and isolated in 213 (67%). The median disease-free interval was 18.5 months. Laparoscopic resection was used in 46% of patients. Surgery was limited to the adrenal gland in 73% of patients and R0 resection was achieved in 86% of cases. The median overall survival was 29 months (95% confidence interval, 24.69-33.30). The survival rates at 1, 2, 3, and 5 years were 80%, 61%, 42%, and 35%, respectively. Patients with renal cancer showed a median survival of 84 months, patients with NSCLC 26 months, and patients with colorectal cancer 29 months (P = .017). Differences in survival between metachronous and synchronous lesions were also significant (30 vs. 23 months; P = .038). CONCLUSION Surgical removal of adrenal metastasis is associated with long-term survival in selected patients.

La cirugía laparoscópica en España. Resultados de la encuesta nacional de la Sección de Cirugía Endoscópica de la Asociación Española de Cirujanos

Resumen Objetivo Conocer la opinion de los cirujanos miembros de la Asociacion Espanola de Cirujanos (AEC) sobre la cirugia laparoscopica (CL) y su implantacion en nuestros hospitales. Material y metodos Dos encuestas de opinion. Una remitida a todos los miembros de la AEC en abril de 2003. Incluia aspectos generales y situaciones clinicas. La otra se remitio a todos los servicios de cirugia del pais e incluia aspectos sobre dotacion e implantacion de la CL. Resultados Han contestado 106 servicios (40%) y 855 cirujanos (32,3%). Solo 209 (25%) cirujanos realizan procedimientos avanzados. El 49% de cirujanos creen que los resultados de la CL son mejores que los de la cirugia convencional y 324 (40%) creen que la CL acabara siendo una superespecialidad. La CL se considera de primera eleccion en el tratamiento de la colelitiasis (99%), reflujo gastroesofagico (RGE) (94%) y colecistitis aguda (81%). En otras afecciones como la hernia inguinal, las enfermedades del bazo, patologia benigna de colon, la obesidad y enfermedades suprarrenales se utilizaria en casos seleccionados. El cancer de colon, la apendicitis y la eventracion tienen una baja aceptacion como primera indicacion en la CL. El 59% de cirujanos considera que la CL no ha tenido el crecimiento esperado. Conclusiones La CL, en nuestro medio y para un amplio colectivo de cirujanos, es ampliamente aceptada para el tratamiento de la colelitiasis y el RGE. A pesar de que nuestros hospitales tienen medios tecnicos suficientes para realizar la CL avanzada, esta se practica por pocos cirujanos. Aspectos como la formacion en CL y la superespecializacion aun quedan por perfilar en un futuro.

Survival and clinicopathological characteristics of breast cancer patient according to different tumour subtypes as determined by hormone receptor and Her2 immunohistochemistry. A single institution survey spanning 1998 to 2010

As far as recent breast cancer molecular subtype classification is concerned, much work has dealt with clinical outcomes for triple negative and Her2 patients. Less is known about the course of patients in the remaining subtypes. Molecular classification based on immunohistochemistry is widely available and correlates well with genetic microarray assessment, but at a lower cost. The aim of our investigation was to correlate immunohistochemical subtypes of breast cancer with clinical characteristics and patient outcomes. Since 1998, 1167 patients operated for 1191 invasive breast tumours were included in our database. Patients were regularly followed up until March 2010. Disease-free survival, overall mortality, and breast cancer-specific mortality at 5 years were calculated for the cohort. 72% of tumours were ER+PR±HER2- group, 13% triple negative (ER-PR-HER2-), 10% ER+PR±HER2+ group, and 5% Her2 (ER-PR-HER2+). Cancer-specific survival was 94.2% for the ER+PR+HER2- subtype, 84.8% for the Her2 subtype, 83.3% for the ER+PR-HER2- subtype, and 78.6% for triple negatives. Distant metastases prevalence ranged from 7% to 22% across subtypes, increasing stepwise from ER+PR+HER2-, ER+PR+HER2+, ER+PR-HER2-, ER+PR-HER2+, ER-PR-HER2+ through triple negative. Small, low-grade tumours with low axillary burden were more likely to belong to the ER+PR±HER2- group. Conversely, larger high-grade tumours with significant axillary burden were more likely to belong to Her2 or triple negative groups. ER+PR±HER2- group patients with negative PR receptors performed more like Her2 or triple negative than like the rest of ER+PR±HER2± groups patients. Molecular classification of breast tumours based only on immunohistochemistry is quite useful on practical clinical grounds, as expected. ER+PR±HER2- group patients with negative PR receptors seem to be at high risk and deserve further consideration.

Comparative Long-term Study of a Large Series of Patients with Invasive Ductal Carcinoma and Invasive Lobular Carcinoma. Loco-Regional Recurrence, Metastasis, and Survival

Our aim was to compare histologic and immunohistochemical features, surgical treatment and clinical course, including disease recurrence, distant metastases, and mortality between patients with invasive ductal carcinoma (IDC) or invasive lobular carcinoma (ILC). We included 1,745 patients operated for 1,789 breast tumors, with 1,639 IDC (1,600 patients) and 145 patients with ILC and 150 breast tumors. The median follow‐up was 76 months. ILC was significantly more likely to be associated with a favorable phenotype. Prevalence of contralateral breast cancer was slightly higher for ILC patients than for IDC patients (4.0% versus 3.2%; p = n.s). ILC was more likely multifocal, estrogen receptor positive, Human Epidermal Growth Factor Receptor‐2 (HER2) negative, and with lower proliferative index compared to IDC. Considering conservative surgery, ILC patients required more frequently re‐excision and/or mastectomy. Prevalence of stage IIB and III stages were significantly more frequent in ILC patients than in IDC patients (37.4% versus 25.3%, p = 0.006). Positive nodes were significantly more frequent in the ILC patients (44.6% versus 37.0%, p = 0.04). After adjustment for tumor size and nodal status, frequencies of recurrence/metastasis, disease‐free and specific survival were similar among patients with IDC and patients with ILC. In conclusion, women with ILC do not have worse clinical outcomes than their counterparts with IDC. Management decisions should be based on individual patient and tumor biologic characteristics rather than on lobular versus ductal histology.

Positive versus negative sentinel nodes in early breast cancer patients: Axillary or loco-regional relapse and survival. A study spanning 2000–2012

Sentinel Node Biopsy (SNB) is a minimally invasive alternative to elective axillary lymph node dissection (ALND) for nodal staging in early breast cancer. The present study was conducted to evaluate prognostic implications of a negative sentinel node (SN) versus a positive SN (followed by completion ALND) in a closely followed-up sample of early breast cancer patients. We studied 889 consecutive breast cancer patients operated for 908 primaries. Patients received adjuvant therapy with chemotherapy, hormone therapy and eventually trastuzumab. Radiation therapy was based on tangential radiation fields that usually included axillary level I. Median follow-up was 47 months. Axillary recurrence was seen in 1.2% (2/162) of positive SN patients, and 0.8% (5/625) of negative SN patients (p = n.s.). There was an overall 3.2% loco-regional failure rate (29/908). Incidence of distant recurrence was 3.3% (23/693) for negative SN patients, and 4.6% (9/196) for positive SN patients (p = n.s.). Overall mortality rate was 4% (8/198) for positive SN patients, while the corresponding specific mortality rate was 2.5% (5/198). For patients with negative SNs, overall mortality was 4.9% (34/693), and the specific mortality was 1.4% (19/693) (p = n.s.). We did not find significant differences in axillary/loco-regional relapse, distant metastases, disease-free interval or mortality between SN negative and SN positive patients, with a follow-up over 4 years.

The Development of Laparoscopic Surgery in Spain

Aim: To assess degree of development and level of acceptance of laparoscopic surgery in Spain. Method: A questionnaire was sent to all members of the Spanish Association of Surgeons in April 2003. It included 32 questions, 9 of which were general, and 23 referred to specific clinical situations, techniques, and standard practice. Results: Eight hundred and fifty-eight (33.1%) surgeons replied. Only 211 (25%) surgeons reported performing advanced laparoscopic procedures. Four hundred and twenty (49%) surgeons believed that the results obtained with laparoscopic surgery were better than those obtained with conventional surgery, and 325 (40%) surgeons believed that laparoscopy would become a superspecialty. Laparoscopic surgery was considered the method of choice in the treatment of gallbladder stones (99%), gastroesophageal reflux disease (94%), acute cholecystitis (81%), in selected cases of inguinal hernia repair, and in procedures to be performed in spleen and adrenals, benign colon disease, and obesity. Three hundred and ninety-eight (47%) surgeons considered laparoscopic surgery the preferred approach for colon cancer, 292 (34%) for appendicitis, and 155 (18%) for incisional hernia. Five hundred and five (59%) surgeons considered that the use of laparoscopic surgery had grown less than expected. Conclusions: The vast majority of surgeons advocated laparoscopic surgery for the treatment of gallbladder stones and gastroesophageal reflux disease. Although most hospitals had the appropriate technical facilities for performing advanced laparoscopic procedures, few surgeons actually did so.

Appendiceal Diverticulosis in Acute Appendicitis: Our Experience and LiteratureReview

Background: The appendiceal diverticulum is an uncommon pathology. Its most common clinical presentation is the appendiceal diverticulitis and the symptoms are similar to acute appendicitis. Also, it can be considered as part of differential diagnosis for chronic abdominal pain. Aim: Analyze the prevalence in our hospital of appendiceal diverticulosis in acute appendicitis and literature review. Methods: Retrospective description study (January 2004 to December 2013) looking for presence of appendix diverticula in 1526 patients after appendectomy due to suspicion of acute appendicitis. Review of literature for term results: “appendiceal”, “appendicular”, “diverticulitis”, “diverticulosis”. Results: Total sample: 2058 patients operated of appendectomy; 1526 of those were to suspicion of acute appendicitis and in 38 of those we found presence of appendiceal diverticula (2.49% prevalence). Distribution: men/ women (68.42%/31.57%), middle age (46.71 years). Lipton classification: Type I (28.94%), type II (34.21%), type III (21.05%) and type IV (15.78%). Other associations: carcinoid tumor (2.36%), villous adenoma (2.63%), serrated adenoma with low grade dysplasia (2.63%), perforated diverticula (7.89%), chronic diverticulitis (5.26%). Conclusion: Prevalence is slightly higher in our series, probably because we considered only patients with acute appendicitis and not all surgical specimens with cecal appendix. According to reviewed bibliography there is possible relation with appendix neoplasias, more risk of perforation and mortality. It is a difficult pre-operative diagnosis and it has to be considered in the differential diagnosis for (acute and chronic) abdominal pain in right iliac fossa.

Cierre de grandes defectos de pared abdominal mediante plastia de epiplón y malla de polipropileno sustitutoria en pacientes con laparostomías descompresivas

When primary abdominal wall closure has not been possible or after open abdominal decompression, the definitive abdominal wall closure can pose surgical problems that are difficult to resolve. Full-thickness abdominal wall defects caused by musculoaponeurotic and skin retraction, whose dimensions impede primary closure after a few days of maintaining an open abdomen open, make it necessary to search for different reconstructive strategies. We present the case of 3 patients with large full-thickness abdominal wall defects secondary to open abdominal decompression due to abdominal compartment syndrome (ACS). Definitive closure involved omentoplasty in order to isolate the abdominal viscera, reinforced with polypropylene (PP) mesh anchored on the oblique muscles retracted to the supraaponeurotic position. In some cases, treatment included a partial skin graft.
