Implantes de carcinoma canalicular infiltrante en trayecto de biopsia estereotáctica con mamótomo
La biopsia estereotáctica con mamótomo constituye
una de las herramientas diagnósticas
empleadas en la evaluación de las lesiones no
palpables de la glándula mamaria. Se ha reportado
como problema potencial el implante
de células tumorales en el trayecto de la aguja,
complicación descrita para otros tumores, pero
con incidencia desconocida en el caso del cáncer
de seno.
A continuación se presenta un reporte de caso
de implantes tumorales documentados en el
trayecto de la aguja de biopsia y una revisión
de la literatura.152-156Stereotactic breast biopsy with the
mammotome device has become one of the available strategies for the evaluation of nonpalpable
breast lesions.
There are some reports of tumoral cells seeding
along the biopsy tract.
In this report, we present a case with
pathologically documented tumoral seeding

Use of screening mammograms in patients diagnosed with breast cancer at Hospital Universitario San Ignacio, Centro Javeriano de Oncología
Introducción. Actualmente el cáncer de seno ha logrado trascender en la salud de las mujeres colombianas, por ser una enfermedad con alta mortalidad. Hoy por hoy, se ofrece tamizaje de oportunidad con mamografía para mujeres mayores de 50 años, pero aún es escasa la información sobre cómo se están detectando los nuevos casos en Colombia.155-166Introduction: Breast cancer has currently become
a health issue amongst Colombian women due its
high mortality rate. Nowadays opportunity
screening is offered with mammograms for women
over 50, nonetheless little information is available
on how new cases are being detected in Colombia.
Objective: Determine the use of screening
mammograms in women with breast cancer who
had an initial consultation with breast surgeons at
Hospital Universitario San Ignacio in Bogotá,
Colombia, between 2004 and 2007.
Methods: A retrospective, descriptive
observational study of 232 newly diagnosed breast
cancer cases was carried out in which the following
data were collected: age at time of diagnosis, chief
complaint, duration of symptoms, tumor size on
clinical breast examination, lymph nodes,
histological type, and clinical stage. For inferential
analysis student´s T and chi square test were used.
Significance was set at p<0.05.
Results: In this population, only 18.1% of the
patients were referred due to abnormal findings on
screening mammograms, while the vast majority
had breast symptoms as a consequence of advanced disease. Those who had lumps, in comparison to
asymptomatic patients, had larger tumors (5.1 cm
versus 3.3 cm, p<0.05), larger lymph node
involvement (46.1% versus 14.3%, p<0.05), and
had a stronger tendency of locally advanced disease
(stage III 43.3% versus 9.5%, p<0.05). Women
over 50 had a low use of screening mammograms
(24.7%) and waited twice as much before having
an appointment with a specialist, when compared
to those less than 50 (p<0.05).
Conclusions: The majority of breast cancer cases
were symptomatic, and early detection was small
in this population; as a consequence, advanced
disease was diagnosed in a larger proportion. These
results contribute to support the growing need to
develop strategies to teach women and health
professionals about the benefits of mammograms,
breast self exam, and clinical breast exam as tools
for early detection
Locally-advanced primary neuroendocrine carcinoma of the breast : case report and review of the literature
Q4Q2Reporte de casoBackground
Primary neuroendocrine carcinoma of the breast is a heterogeneous group of rare tumors with positive immunoreactivity to neuroendocrine markers in at least 50% of cells. Diagnosis also requires that other primary sites be ruled out and that the same tumor show histological evidence of a breast in situ component. Primary neuroendocrine carcinoma of the breast rarely presents as locally advanced disease and less frequently with such widespread metastatic disease as described herein. The review accompanying this case report is the first to provide an overview of all the cases of primary neuroendocrine carcinoma of the breast published in the literature and encompasses detailed information regarding epidemiology, histogenesis, clinical and histologic diagnosis criteria, classification, surgical and adjuvant treatment, as well as prognosis. We also provide recommendations for common clinical and histologic pitfalls associated with this tumor.
Case presentation
We describe a case of a 51-year-old Hispanic woman initially diagnosed with locally-advanced invasive ductal carcinoma that did not respond to neodjuvant treatment. After undergoing modified radical mastectomy the final surgical pathology showed evidence of alveolar-type primary neuroendocrine carcinoma of the breast. The patient was treated with cisplatin/etoposide followed by paclitaxel/carboplatinum. Thirteen months after surgery the patient is alive, but developed pulmonary, bone, and hepatic metastasis.
Conclusion
The breast in situ component of primary neuroendocrine carcinoma of the breast may prevail on a core biopsy samples increasing the probability of underdiagnosing this tumor preoperatively. Being aware of the existence of this disease allows for timely diagnosis and management. Optimal treatment requires simultaneous consideration of both the neuroendocrine and breast in situ tumor features
Determining the use of prophylactic antibiotics in breast cancer surgeries : a survey of practice
Q3Q2Background: Prophylactic antibiotics (PAs) are beneficial to breast cancer patients undergoing surgery because they prevent surgical site infection (SSI), but limited information regarding their use has been published. This study aims to determine the use of PAs prior to breast cancer surgery amongst breast surgeons in Colombia.
Methods: An online survey was distributed amongst the breast surgeon members of the Colombian Association of Mastology, the only breast surgery society of Colombia. The scope of the questions included demographics, clinical practice characteristics, PA prescription characteristics, and the use of PAs in common breast surgical procedures.
Results: The survey was distributed amongst eighty-eight breast surgeons of whom forty-seven responded (response rate: 53.4%). Forty surgeons (85.1%) reported using PAs prior to surgery of which >60% used PAs during mastectomy, axillary lymph node dissection, and/or breast reconstruction. Surgeons reported they targeted the use of PAs in cases in which patients had any of the following SSI risk factors: diabetes mellitus, drains in situ, obesity, and neoadjuvant therapy. The distribution of the self-reported PA dosing regimens was as follows: single pre-operative fixed-dose (27.7%), single preoperative dose followed by a second dose if the surgery was prolonged (44.7%), single preoperative dose followed by one or more postoperative doses for >24 hours (10.6%), and single preoperative weight-adjusted dose (2.1%).
Conclusion: Although this group of breast surgeons is aware of the importance of PAs in breast cancer surgery there is a discrepancy in how they use it, specifically with regards to prescription and timeliness of drug administration. Our findings call for targeted quality-improvement initiatives, such as standardized national guidelines, which can provide sufficient evidence for all stakeholders and therefore facilitate best practice medicine for breast cancer surgery
Penetrating wounds of the back and flank : analysis of 77 cases
Q4Q3To determine the factors that allow early recognition of injuries to the intrathoracic and intra-abdominal organs in patients with penetrating wounds to the lower thorax and abdomen with site of entrance located in the back or flanks, we retrospectively analyzed the cases of 77 such patients. There were 65 stab wounds (85%) and 12 gunshot wounds (15%). The injuries were confined to the abdomen in 46 (60%); 39 were stab wounds and seven were gunshot wounds. The wounds were confined to the chest in 24 patients (31%) and involved both the chest and abdomen in seven cases (9%). Of the 53 abdominal wounds, 21 necessitated celiotomy; in 20 of them, an intra-abdominal organ was found injured, and one patient died (1.9%). Of the 24 injuries confined to the chest, only one patient required emergency thoracotomy due to massive hemorrhage; all 24 patients survived. All of the seven thoracoabdominal injuries, two produced by gunshot and five by stabbing, necessitated celiotomy. Most patients with gunshot wounds to the back and flanks require celiotomy, but a selective therapy can be safely used in patients with stab wounds. The rate of negative exploratory celiotomy was less than 5%; the mortality was 1.3%.Revista Internacional - No indexad
