Enfoque oncoplástico en el tratamiento quirúrgico conservador del cáncer de mama. Una revisión bibliográfica / Oncoplastic approach in the conservative surgical treatment of breast cancer. A bibliographic review

Introducción: El cáncer de mama es el más común en el mundo y constituye la principal causa de muerte en mujeres, no obstante, los avances terapéuticos han permitido aumentar sus tasas de supervivencia global, libre de enfermedad. Procurando una mejor calidad de vida surge la cirugía oncoplástica, que combina la cirugía plástica y reconstructiva en el ma-nejo quirúrgico del cáncer de mama localmente avanzado, de mayor tamaño o con ubicación desfavorable, buscando mejorar el resultado estético sin perjuicio del resultado oncológico. Objetivo: Realizar una revisión bibliográfica actualizada del enfoque oncoplástico en el tra-tamiento quirúrgico conservador del cáncer de mama, con el propósito de conocer sus re-sultados oncológicos y estéticos en comparación con los tratamientos quirúrgicos conven-cionales.Material y Métodos: La búsqueda bibliográfica se llevó a cabo en las bases de datos Pub-Med, Elsevier, Hinari, Cochrane y ScienceDirect. Seleccionando los artículos publicados du-rante los últimos 10 años, en inglés o español, que tuvieron relación con información relevan-te en el tratamiento quirúrgico oncoplástico conservador del cáncer de mama.Resultados: Los criterios de búsqueda incluyeron artículos sobre el tratamiento quirúrgico oncoplástico conservador en mujeres con cáncer de mama primario, 99 artículos cumplie-ron los criterios, excluyéndose aquellos publicados hace más de 10 años, con metodología poco clara o no reproducible. Fueron elegibles 35 por ser relevantes al tema, publicados en revistas indexadas entre los años 2011 y 2021, permitiendo determinar los resultados clíni-cos, oncológicos y estéticos de la cirugía oncoplástica conservadora y contrastarlos con las técnicas convencionales. Conclusión: La cirugía oncoplástica conservadora de mama es oncológicamente segura y equiparable a las cirugías convencionales (mastectomía total o parcial), ofreciendo resulta-dos estéticos más satisfactorios y mejorando la calidad de vida de las pacientes.

Background: Breast cancer is the most common cancer in the world and represents the main cause of death in women; nevertheless, therapeutic advances have made it possible to increase overall and disease-free survival rates. Looking for a better quality of life, on-coplastic surgery arises, which combines plastic and reconstructive surgery in the surgical management of locally advanced breast cancer, larger or with unfavorable location, seeking to improve the appearance without affecting the oncologic result.Objective: To perform an updated bibliographic review of the oncoplastic approach in the conservative surgical treatment of breast cancer, with the purpose of knowing its oncologic and esthetic results compared to conventional surgical treatments.Material and Methods: The bibliographic search was carried out in the databases PubMed, Elsevier, Hinari, Cochrane and ScienceDirect. Selecting the articles published during the last 10 years, in either English or Spanish, that were related to relevant information in the conser-vative oncoplastic surgical treatment of breast cancer.Results: The search criteria included articles on conservative oncoplastic surgical treatment in women with primary breast cancer, 99 articles met the criteria, excluding those published more than 10 years ago, with unclear or non-reproducible methodology. 35 were eligible, because they were relevant to the subject, published in indexed journals between 2011 and 2021, allowing to determine the clinical, oncological and aesthetic results of conservative oncoplastic surgery and contrast them with conventional techniques. Conclusion: Oncoplastic breast-conserving surgery is oncologically safe and comparable to conventional surgeries (total or partial mastectomy), offering more satisfactory esthetic results and improving the quality of life in patients.

Influence of surgical technique on complications, readmissions and clinical progress of breast cancer in women participating in screening programs / Influencia de la técnica quirúrgica en las complicaciones, reingresos y evolución clínica del cáncer de mama en mujeres participantes en programas de cribado poblacional

Introduction: Complications and readmissions derived from surgical treatment of breast cancer have been less evaluated than recurrence and mortality. The aim of this study was to analyze the results of surgical treatment and prognosis in a screening population with known high surgical variability.Methods: This multicenter study included 1086 women diagnosed with breast cancer from the CaMISS cohort study of women aged between 50 and 69years participating in four breast cancer screening programs in Spain between 2000 and 2009 with a follow-up until 2014. Multivariate models were used to estimate the adjusted odds ratio of breast surgery (mastectomy vs conservative treatment) for complications and readmissions and hazard ratios for recurrences and mortality.Results: Primary breast surgical treatment consisted of conservative treatment in 821 women (80.1%) and mastectomy in 204 (19.9%). Mastectomy was associated with readmissions, recurrences and mortality but this association was not statistically significant on multivariate adjusted analysis (ORa=1.51 [95%CI 0.89–2.57], HRa=1.37 [95%CI 0.85–2.19] and HRa=1.52 [95%CI 0.95–2.43] respectively). In our sample, the variables with greatest impact on complications, recurrences and mortality were stages III and IV (ORa=4.4[95%CI 1.22–16.16], HRa=7.96 [95%CI 3.32–19.06] and HRa=3.92[95%CI 1.77–8.67]).Conclusion: Complications, readmissions, recurrence and mortality were similar in both surgical techniques. These results support that surgical treatment for breast cancer can be adapted to professional and health system circumstances, and to the surgical needs and desires of each patient. At a time when screening programs are being questioned the variable with the greatest impact on mortality was stage III and IV. (AU)

Introducción: Las complicaciones y los reingresos derivados del tratamiento quirúrgico del cáncer de mama han sido menos evaluados que la recidiva y la mortalidad. El objetivo de este estudio ha sido analizar los resultados y el pronóstico del cáncer de mama en función del tipo de cirugía recibida en una población con elevada variabilidad quirúrgica.Métodos: En este estudio multicéntrico se incluyeron 1086 mujeres diagnosticadas de cáncer de mama de la cohorte CaMISS, con mujeres de entre 50 y 69 años participantes en 4 programas de cribado Españoles entre 2000 y 2009, con seguimiento hasta 2014. Se utilizó la regresión logística multivariada para estimar la odds ratio de complicaciones y reingresos. También modelos Cox para estimar hazard ratios de recidivas y mortalidad.Resultados: Se realizó cirugía conservadora en 821 mujeres (80,1%) y mastectomía en 204 (19,9%). La mastectomía se asoció con reingresos, recidivas y mortalidad, pero esta asociación no fue estadísticamente significativa en el análisis multivariado ajustado (ORa=1,51[IC95% 0,89-2,57], HRa=1,37[IC95% 0,85-2,19] y HRa=1,52[IC95% 0,95-2,43] respectivamente). La variable con mayor impacto sobre complicaciones, recidivas y mortalidad fue el estadio III/IV (ORa=4,4[IC 95%: 1,22-16,16], HRa=7,96[IC 95%: 3,32-19,06] y HRa=3,92[IC 95%: 1,77-8,67]).Conclusión: Las complicaciones, reingresos, recidiva y mortalidad fueron estadísticamente equivalentes en ambas técnicas quirúrgicas. El tratamiento quirúrgico del cáncer de mama puede adaptarse a las circunstancias profesionales, del sistema sanitario además de necesidades y deseos quirúrgicos de cada paciente. En un momento en que se cuestionan los programas de cribado, la variable con mayor impacto en mortalidad fue el estadio.

Underestimation of invasive breast carcinoma in patients with initial diagnosis of ductal carcinoma in situ: Size matters.

BACKGROUND: The aim of our study was to identify those patients with preoperative diagnosis of ductal carcinoma in situ (DCIS) and high risk of upstaging to invasive breast carcinoma (IBC), in whom sentinel lymph node biopsy (SLNB) should be considered. MATERIALS AND METHODS: One-hundred and five DCIS patients treated with breast-conserving surgery (BCS) or mastectomy were studied. Preoperative features of the tumours were analyzed to investigate its association with underestimation of IBC on final pathology. RESULTS: Overall, the underestimation rate of IBC was 16.2%. The underestimation rate was highest in lesions with initial size >2 cm compared with those with size ≤2 cm (26.8% vs. 4.1%, respectively; p < 0.003). Eighty-eight patients (83.8%) underwent concurrent SLNB and only one case had lymph node involvement (1.1%). CONCLUSIONS: SLNB should be considered in DCIS patients receiving BCS with lesions greater than 2 cm since approximately one in four will harbour an IBC.

Infraestimación de carcinoma infiltrante de mama en pacientes con diagnóstico inicial de carcinoma ductal in situ: el tamaño importa / Underestimation of invasive breast carcinoma in patients with initial diagnosis of ductal carcinoma in situ: Size matters

Introducción: El objetivo de nuestro estudio consistió en identificar aquellas pacientes con diagnóstico preoperatorio de carcinoma ductal in situ (CDIS) y alto riesgo de presentar un carcinoma infiltrante en la lesión, en las que se debería considerar realizar una biopsia selectiva de ganglio centinela (BSGC). Métodos: Se estudiaron 105 pacientes con CDIS tratadas mediante cirugía conservadora o mastectomía. Se analizaron las características preoperatorias de los tumores para investigar su asociación con la infraestimación de carcinoma infiltrante. Resultados: El porcentaje global de infraestimación de carcinoma infiltrante fue del 16,2%. El porcentaje de infraestimación fue mayor en las lesiones con un tamaño inicial superior a 2 cm en comparación con las lesiones con un tamaño igual o menor a 2 cm (26,8% vs. 4,1%, respectivamente; p < 0,003). Se realizó la BSGC en 88 pacientes (83,8%), encontrándose afectación ganglionar en un solo caso (1,1%). Conclusiones: En pacientes con diagnóstico inicial de CDIS tratadas mediante cirugía conservadora, se debería considerar realizar una BSGC cuando el tamaño de la lesión es superior a 2 cm, ya que uno de cada cuatro casos albergará la presencia de un carcinoma infiltrante.

BACKGROUND: Breast cancer ranks first among cancers that affect women worldwide, representing 16% of female cancers. The surgical approach to breast cancer has undergone changes over the years, reducing morbidity and mortality and improving life quality for these patients. The purpose of this study is to analyze the surgical approach in patients treated in the Oncologic Surgery unit of José Carrasco Arteaga Hospital. METHODS: Cross-sectional observational study to analyze the prevalence of breast cancer surgeries performed in the Oncologic Surgery Unit of José Carrasco Arteaga Hospital. Variables such as age, diagnosis, histological type, stage, location, type of surgical procedure and surgical margins were included. All the data was analyzed with descriptive statistics using SPSS version 24.0. RESULTS: 66 patients were included in the study. The percentages of conservative surgeries and mastectomies were 56.06% versus 43.94% respectively. The most frequent histological type was infiltrating ductal carcinoma (75.74%). Of the total of patients diagnosed with breast cancer, 46.97% were in clinical stage IIB; the upper external quadrant was affected in 72.7% of patients and the most frequent location was the left side (50%). CONCLUSIONS: Breast cancer occurs most frequently in postmenopausal women, the most frequent histological type is infiltrating ductal carcinoma, and the percentage of conservative surgeries is greater than mastectomies.(AU)

Prospective, randomized comparative study of ultrasound-guided blocking of the lateral cutaneous branches of the intercostal nerves versus conventional analgesia in non-reconstructive breast surgery. / Estudio prospectivo, aleatorizado comparativo entre el bloqueo guiado por ultrasonidos de las ramas cutáneas laterales de los nervios intercostales frente a analgesia convencional en cirugía no reconstructiva de mama.

OBJECTIVE: The objective of this study is to determine whether the accomplishment of an interfascial blockade, the blocking of the cutaneous branches of the intercostal nerves in the axillary line (BRILMA) associated with a multimodal analgesic regimen improves post-operative analgesia and allows saving opioids after non-reconstructive surgery of breast. MATERIAL AND METHODS: A prospective, randomised and simple blind study was conducted on patients that underwent non-reconstructive breast surgery. The patients were randomly assigned to the blocking group, or to the standard post-operative analgesia group (paracetamol and dexketoprofen). The main variables analysed were the pain intensity assessed by the verbal numerical scale and the analgesic rescue needs with tramadol. RESULTS: Statistically significant differences were observed in the consumption of tramadol during the study period (10.5mg in the BRILMA group, compared to 34.3 in the control group, P=.0001). There were also differences in the pain assessment, with lower values found in the BRILMA group. CONCLUSIONS: In non-reconstructive breast surgery, performing a BRILMA block allows obtaining lower pain scores, which implies less need for rescue analgesics and a significant saving of tramadol in the study period.

Caso Clínico: Carcinoma Papilar Sólido de Mama / Case Report: Breast Papillary Solid Carcinoma

INTRODUCCIÓN: El carcinoma papilar sólido de mama es un subtipo poco frecuente de carcinomas mamarios representando el 1 ­ 2 % y principalmente en mujeres postmenopáusicas. Su diagnóstico desde el punto de vista clínico, imagenológico y patológico es difícil. El tratamiento no está estandarizado por el bajo porcentaje de casos reportados, actualmente es aceptada la cirugía conservadora, la radioterapia, existiendo controversia en la hormonoterapia y el vaciamiento axilar, pues las metástasis ganglionares ascienden únicamente al 2 %. Su pronóstico es bueno y la complicación más común es la recidiva local. CASO CLÍNICO: Paciente femenina de 80 años, acudió a consulta por presentar una masa a nivel de mama izquierda al realizarse una autoexploración, donde identificó un nódulo de 2 cm aproximadamente. EVOLUCIÓN: Se realizó una mamografía, ecografía mamaria y la citología mamaria que dio como resultado un tumor, inicialmente se consideró como Phyllodes. Tras el diagnóstico se realizó una lumpectomía, y la patología de la pieza quirúrgica fue de un carcinoma papilar sólido, luego recibió radioterapia y vigilancia médica. CONCLUSIÓN: La autoexploración fue un pilar fundamental en el diagnóstico de este caso y alertó a la paciente a buscar valoración médica. Al tratarse de un caso poco frecuente el diagnóstico definitivo fue la patología.

BACKGROUND: Solid papillary carcinoma of the breast is a rare subtype of mammary carcinomas corresponding to 1 ­ 2 % and mainly in postmenopausal women. It is diagnosis from the clinical, imaging and pathological point of view is difficult. The treatment is not standardized due to the low percentage of cases reported, conservative surgery, radiotherapy is currently accepted, and controversy exists in hormone therapy and axillary emptying, as lymph node metastases amount to only 2 %. It is prognosis is good and the most common complication is local recurrence. CASE REPORT: An 80-year-old female patient attended the consultation by presented a mass at the level of the left breast when performing the self-examination, where identified a 2 cm nodule. EVOLUTION: Mammography, mammary ultrasound and mammary cytology outcome in a tumor, was initially considered as Phyllodes. After the diagnosis a lumpectomy was performed, and the pathology of the surgical piece was of a solid papillary carcinoma, then received radiotherapy and surveillance. CONCLUSIONS: Self-examination was a fundamental pillar in the diagnosis of this case and alerts the patient to seek medical assessment. Being a rare case, the definitive diagnosis was pathology.
