RESUMEN

Introducción: El cáncer ha causado más muertes que todas las guerras y catástrofes conocidas. En particular, el cáncer de mama se ha convertido en una pandemia que amenaza con seguir propagándose. Objetivo: Describir las diferencias en cuanto a los resultados obtenidos de la cirugía conservadora y radical como tratamiento del cáncer de mama. Métodos: Se realizó un estudio analítico, observacional, descriptivo y retrospectivo en un universo de 177 pacientes con diagnóstico de cáncer de mama en el servicio de Cirugía General del Centro de Investigaciones Médico Quirúrgicas de La Habana, Cuba. Todas recibieron tratamiento quirúrgico en el período comprendido de enero de 2011 a diciembre de 2016. Resultados: De las pacientes estudiadas, el 92,09 por ciento no presentaron antecedentes de patología mamaria, mientras que el 36,72 por ciento tuvieron como antecedente patológico familiar cáncer de mama. Predominaron las pacientes mayores de 70 años en ambas técnicas quirúrgicas. En el grupo de 30-40 años solamente se practicaron técnicas conservadoras. Con respecto al estadiamiento, predominó la etapa II de la enfermedad. La sobrevida global a los 5 años fue superior al 90 por ciento, mientras que el intervalo libre de enfermedad se mantuvo en valores similares para ambas técnicas. Conclusiones: Se realizaron mayor número de cirugías conservadoras de mama en pacientes que se encontraban en etapas clínicas más tempranas de la enfermedad y la sobrevida global de los procedimientos conservadores fue ligeramente mayor(AU)

Introduction: Cancer has caused more deaths than all known wars and catastrophes. Particularly speaking, breast cancer has become a pandemic that threatens to continue to spread. Objective: To describe the differences based on the results obtained from conservative and radical surgery as a treatment for breast cancer. Methods: An analytical, observational, descriptive and retrospective study was carried out with a universe of 177 female patients diagnosed with breast cancer in the general surgery service of Centro de Investigaciones Médico Quirúrgicas, of La Habana, Cuba. All of them received surgical treatment in the period from January 2011 to December 2016. Results: 92.09 percent of the patients studied had no history of breast pathology, while 36.72 percent had breast cancer as a family pathological history. Patients over 70 years of age predominated in both surgical techniques. In the group of 30-40 years of age only conservative techniques were performed. With respect to staging, there was a predominance of the disease in stage II. Overall survival at 5 years was higher than 90 percent, while the disease-free interval remained at similar values for both techniques. Conclusions: A greater amount of breast-conserving surgeries were performed in patients at earlier clinical stages of the disease, while overall survival of conservative procedures was slightly higher(AU)

RESUMEN

Cervical cancer (CC) remains a public health issue worldwide despite preventive measures. Surgical treatment in the early-stage CC has evolved during the last decades. Our aim was to review the advances in the literature and summarize the ongoing studies on this topic. To this end, we conducted a literature review through PubMed focusing on English-language articles on the surgical management of early-stage CC. The emergent topics considered here are the FIGO 2018 staging system update, conservative management with less radical procedures for selected patients, lymph node staging, fertility preservation, preferred surgical approach, management of tumors up to 2 cm, and prognosis. In terms of updating FIGO, we highlight the inclusion of lymph node status on staging and the possibility of imaging. Regarding the preferred surgical approach, we emphasize the LACC trial impact worldwide in favor of open surgery; however, we discuss the controversial application of this for tumors < 2 cm. In summary, all topics show a tendency to provide patients with tailored treatment that avoids morbidity while maintaining oncologic safety, which is already possible in high-income countries. We believe that efforts should focus on making this a reality for low-income countries as well.

RESUMEN

Resumen OBJETIVO: Comparar la cirugía radical con la cirugía conservadora de la fertilidad en mujeres con cáncer de ovario epitelial en estadio 1A-C con respecto a la tasa de recurrencia y las tasas de supervivencia. Además, evaluar los desenlaces reproductivos y obstétricos para las mujeres con cáncer de ovario epitelial en estadio I tratadas con una conducta conservadora de la fertilidad. PACIENTES Y MÉTODOS: Estudio prospectivo efectuado en pacientes con cáncer de ovario epitelial, estadio I, con edad ≤ 40 años. A las pacientes del grupo de preservación de la fertilidad se les practicó salpingooforectomía del lado del ovario afectado y una biopsia por incisión o escisión en cuña del ovario contralateral. A las pacientes del grupo de cirugía radical se les practicó la histerectomía total y salpingooforectomía bilateral. Para evaluar los desenlaces reproductivos y oncológicos se dio seguimiento a todas las pacientes durante cinco años. RESULTADOS: Se estudiaron 60 pacientes; las del grupo de cirugía de preservación de la fertilidad eran significativamente más jóvenes (30 ± 4 en comparación con 35 ± 5) (p < 0.001), el tamaño de sus tumores era más pequeño 3.4 ± 1.3 en comparación con 6.0 ± 2,6 (p < 0.001), de menor grado (p < 0.001). = 0.011), estadio más precoz (p < 0.001) y con más histología mucinosa que las pacientes del grupo de cirugía radical. No hubo diferencias estadísticamente significativas entre ambos grupos en cuanto a la recurrencia tumoral o las tasas de supervivencia. De 25 pacientes operadas para preservación de la fertilidad 18 de 25 intentaron quedar embarazadas. Se registraron 15 de 18 embarazos, incluidos 13 nacidos vivos, 1 aborto espontáneo y 1 muerte fetal intrauterina. CONCLUSIÓN: La cirugía conservadora de la fertilidad podría ser una alternativa adecuada a la cirugía radical para mujeres jóvenes con cáncer epitelial de ovario en estadio I.

Abstract OBJECTIVE: In the current study, we aimed to compare between radical surgery and fertility saving surgery in females with stage 1A-C EOC regarding recurrence rate and patients survival rates in addition to evaluating reproductive and obstetric outcomes for stage I EOC females who were managed by fertility saving surgery. PATIENTS AND METHODS: We prospectively identified 60 patients diagnosed with stage I EOC aged ≤ 40 years. Patients in the fertility-preservation group underwent salpingo-oophorectomy on the side of the affected ovary in addition to incisional biopsy or wedge excision of the ovary on the other side. Patients in the radical surgery group underwent total hysterectomy and bilateral salpingo-oophorectomy. We followed up all patients for 5 years to assess their reproductive and oncological outcomes. RESULTS: Patients in the fertility preservation surgery group were significantly younger (30 ± 4 versus 35 ± 5) (p < 0.001), their tumor sizes were smaller 3.4 ± 1.3 versus 6.0 ± 2.6 (p < 0.001), of lower grade (p = 0.011), earlier stage (p < 0.001) and has more mucinous histology than patients in the radical surgery group. There were no statistically significant differences between both groups regarding tumor recurrence or survival rates. Of 25 patients underwent fertility preservation surgery, 18/25 (72%) tried to get pregnant. 15/18 (83%) pregnancies were recorded, including 13 live births, 1 miscarriage, and 1 intrauterine fetal death. CONCLUSION: Fertility sparing surgery could be adequate alternative to radical surgery for young females with stage I EOC.

RESUMEN

OBJECTIVE: To describe a novel end-to-end "true" reinforced stapling colorectal anastomosis and to assess surgical outcomes in a large case series of advanced cancer patients undergoing this procedure. Anastomotic leakage (AL) remains the main concern following surgery for colorectal cancer. METHODS: Between September 2006 and May 2018, in the context of the Catalonian Program of Peritoneal Carcinomatosis, 1193 consecutive patients with advanced abdominal and/or pelvic tumors were included in a prospective single-center study. They underwent cytoreductive radical surgery (CRS) in most cases combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Among other surgical procedures, 374 patients underwent rectal resection and colorectal/ileorectal anastomosis, whether alone or associated to other digestive anastomosis. Key aspects of colorectal anastomosis technique were: (1) complete dissection and mobilization of the distal third of the rectum, (2) placement of a stitch that included both ends of the linear stapling of the rectal stump that was knotted on the anvil of the circular stapler, (3) "cleaning" the fatty tissue of the intestinal ends, (4) adjustment of the height of staples to the thickness of the intestinal wall, and (5) a second layer of interrupted nonperforating sutures placed circumferentially to reinforce the stapled anastomoses. A diverting stoma was not performed. RESULTS: According to clinical criteria, of the 1193 patients included, 296 cases underwent CRS (group 1) and 897 cases CRS + HIPEC (group 2). In group 1, 332 surgical procedures were performed, with 248 digestive anastomoses, of which 98 (39.5%) were colorectal anastomoses, associated to other digestive anastomosis in 37 cases. In group 2, 972 surgical procedures were performed, with 707 digestive anastomoses, of which 263 were colorectal (37.2%), 116 were associated with other digestive anastomosis. Ileocolic anastomosis was the most frequently associated digestive anastomosis. 71 major urinary reconstructions, 283 radical hysterectomies and no diverting stoma were performed. Globally, there was only three colo-ileorectal AL (3/374 = 0.8%). The overall 90-day mortality rate was 0.25%. CONCLUSIONS: A technical modification to create a "true" end-to-end and completely circular reinforced anastomosis effectively prevents anastomotic leakage in patients with advanced tumors undergoing radical resection of the rectum, with no need of diverting stoma.

RESUMEN

The treatment of ovarian cancer should be appropriate, since clinical and surgical decisions may affect the prognosis; the surgery must be performed by an expert oncological surgeon or gynecological oncologist, it's fundamental roles are cancer staging and cytoreduction. The concept of staging surgery in early stages has its justification in the fact that up to 11% of "early ovarian cancers" will have metastasis in different sites of the peritoneal cavity at the time of diagnosis. In advanced stages of epithelial ovarian cancer, the goal is the complete cytoreduction of all visible macroscopic disease, since this variable is the most strongly associated with increased overall survival and disease-free period. The ideal time for cytoreductive surgery in relation to chemotherapy (before or after) is still under debate. In 2010 a randomized trial (EORTC) was published, comparing 310 patients initially operated (followed by adjuvant chemotherapy) versus 322 patients initially treated with neoadjuvant chemotherapy (followed by cytoreductive surgery); no significant differences in overall survival between groups were found. Another important factor playing a role in survival and in the probability of surgical cytoreductive success is tumor biology; there has been described a clear difference between serous and mucinous tumors, but some groups advocate that maximal surgical effort in mucinous tumors may compensate morbidity with an increase in survival. The extension of resection in cytoreduction is still controversial; some authors have confirmed that the most important factor is the residual disease and that radical surgery is superior to non-radical surgery in terms of overall survival. The need and extent of lymphadenectomy in advanced cancer will be treated in another chapter of this issue. Undoubtedly, an important factor is to perform procedures in specialized centers.

RESUMEN

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignant tumor and its incidence is increasing over the world. At present times, radical liver resection is still the most effective treatment for ICC patients to achieve long term survival. Pathological lymph node metastases (LMN), found in 15% to 45% of the patients, have been recognized as an extremely poor prognostic risk factor, even if curative resection is performed. So, considering this issue, it acquires relevance to determine the validity of surgical resection for LNM cases that are diagnosed in the preoperative setting, or whether a routine lymphadenectomy should be performed systematically in all hepatectomies for ICC. The role of routine lymphadenectomy in the surgical treatment of ICC remains controversial, with some centers considering it standard whereas other surgeons perform lymphadenectomy only as a selective indication. Recently, a growing widespread adoption of lymphadenectomy was demonstrated that nearly doubled its commonly reported execution rate. The newly updated eight edition of the American Joint Committee on Cancer (AJCC) staging system now recommends that six nodes need to be analyzed to stage patients with ICC. In this review, we analyzed and summarized some anatomic considerations of the lymphatic anatomy of the liver and the current knowledge and potential advantages of performing a routine lymphadenectomy in patients with ICC, especially looking at pathological staging, prognosis, prevention of local recurrence and outcome. New areas like lymphadenectomy in cirrhotic patients and laparoscopic lymphadenectomy are also discussed.

RESUMEN

The treatment of patients with vulvar cancer remains challenging for gynecologic oncologists. Up to 30 % of the cases are diagnosed in a clinical condition of irresectability, and some kind of strategy has to be taken into account beyond surgery. In this regard, a common and standard definition is critical to maximize oncological results and minimize complications after treatments. Each patient treatment must be tailored individually according to their clinical and biological features and to the setting in which they are dealing with.
