Surgical Management of Vulvar Melanoma: A Case Series.

Vulvar malignant melanoma is the second most common subtype of vulvar cancer, accounting for 5-10% of all vulvar cancers. The prognosis is still very poor, although some advances have been achieved in the last years. One of the most significant changes in its management has been the development of less invasive surgical techniques that diminish the risk of postoperative morbidity and long-lasting sequelae. In this article, we review the surgical management of the pathology, based on the comment of 3 cases with vulvar melanoma treated at our institution.

Breast sarcoma. A case report and review of literature.

INTRODUCTION: Breast sarcomas are rare with an annual incidence of 4.6 cases/1,000,000 women. They can appear as primary forms or secondary to radiation therapy or chronic lymphedema. PRESENTATION OF CASE: A 41 year old woman attended our hospital after having noticed an increase in the size of her fibroadenoma. The examination revealed a 7cm retroareolar nodule. Breast sonography described a hypoechoic bilobulated lesion and MRI showed a large size polinodular image, suggesting a Phyllodes tumor. A core needle biopsy was performed with a histological result of low-grade fusiform cells sarcoma on Phyllodes tumor so we proceeded to surgical treatment with a mastectomy. After two years and a half she noticed a tough nodule over the mastectomy scar, which was resected with a histological result of fusiform cells sarcoma. Considering the diagnosis of recurrence of the disease, surgery was undertaken. DISCUSSION: Breast sarcoma is a rare but aggressive entity. Core biopsy is the procedure of choice for the diagnosis. Lymphatic spread is uncommon so nodal status in breast sarcoma is less informative. Staging study differs from other breast tumors and chest computed tomography is helpful since lungs are the predominant metastatic sites. The use of radiotherapy or chemotherapy is controversial and will depend on the risk of tumor recurrence. CONCLUSION: Surgery represents the only potentially curative therapy for breast sarcoma. Tumor size and adequate resection margin are the most important prognostic factors. Approximately 80% of recurrences appear in the first two years.

Live birth using vitrified--warmed oocytes in invasive ovarian cancer: case report and literature review.

This article reports the live birth of a healthy newborn using vitrified-warmed oocytes in a young patient with invasive mucinous ovarian carcinoma (stage Ic). Diagnosis was performed after a laparoscopic left adnexectomy. She underwent two cycles of ovarian stimulation, and 14 oocytes were vitrified before fertility-sparing surgery with uterus preservation went ahead. One year later, a transfer of two embryos was performed after insemination of warmed oocytes. Eighteen days after the transfer, she underwent a laparotomy because of abdominal pain, vaginal bleeding and haemoperitoneum. A right cornual ectopic pregnancy in the uterus was diagnosed and a wedge resection was performed to resolve it. One week later, a viable intrauterine pregnancy was confirmed under ultrasound. An elective Caesarean section was performed at week 38 of gestation, resulting in the birth of a healthy boy weighing 2650 g. As far as is known, this is the first live birth reported through vitrified-warmed oocytes in a patient with invasive ovarian cancer. Although oocyte vitrification is an alternative to be considered for fertility preservation in highly selected cases of ovarian cancer, controversial issues are discussed. Fertility preservation is a proven possibility in some cancer patients according to their age, disease and time available until the beginning of their oncological treatment. Although oocyte vitrification is an alternative to be considered for fertility preservation in highly selected cases of ovarian cancer, no live birth has been reported.

To our knowledge, this is the first live birth reported using vitrified-warmed oocytes in invasive ovarian cancer. Controversial issues are reviewed and discussed.

[Pregnancy-Associated Breast Cancer: An analytical observational study]. / Cáncer de mama asociado al embarazo: estudio analítico observacional.

BACKGROUND AND OBJECTIVE: Pregnancy-associated breast cancer is defined as breast cancer diagnosed during pregnancy and up to one year postpartum. PATIENTS AND METHOD: A retrospective, analytical, observational study comparing 56 cases of breast cancer and pregnancy (PABC) diagnosed 1976-2008 with 73 patients with breast cancer not associated with pregnancy (non-PABC) was performed. Demographic data, prognostic factors, treatment and survival were reviewed and compared. RESULTS: The prevalence of PABC in our center is 8.3/10,000. The highest frequency (62%) appeared during the postpartum period. The stages are higher in PABC, being 31.3% advanced (EIII and EIV) in PABC versus 13.3% in non-PABC (P < .05). Regarding prognostic factors, 27.3% in PABC had a tumoral grade 3 versus 15.8% of non-PABC. Among women with PABC, 33.3% had negative estrogen receptors, 48.7% negative progesterone receptors and 34.5% positive Her2Neu compared with 22.2, 24.1 and 31%, respectively of non-PABC patients. Finally, positive lymph nodes were found in 52.8% of PABC, versus 33.8% non-PABC (P < .05). Overall and disease-free survival rate at 5 years for PABC was 63.7 and 74.2%, respectively. CONCLUSIONS: The poorer survival observed is possibly due to the presence of adverse prognostic features such as lymph node metastases, negative hormone receptors, tumoral grade iii, as well as a delay in diagnosis with a higher rate of advanced stages.

Complete axillary lymph node dissection versus clinical follow-up in breast cancer patients with sentinel node micrometastasis: final results from the multicenter clinical trial AATRM 048/13/2000.

BACKGROUND: It has been suggested that selective sentinel node (SN) biopsy alone can be used to manage early breast cancer, but definite evidence to support this notion is lacking. The aim of this study was to investigate whether refraining from completion axillary lymph node dissection (ALND) suffices to produce the same prognostic information and disease control as proceeding with completion ALND in early breast cancer patients showing micrometastasis at SN biopsy. METHODS: This prospective, randomized clinical trial included patients with newly diagnosed early-stage breast cancer (T<3.5 cm, clinical N0, M0) who underwent surgical excision as primary treatment. All had micrometastatic SN. Patients were randomly assigned to one of the two study arms: complete ALND (control arm) or clinical follow-up (experimental arm). Median follow-up was 5 years, recurrence was assessed, and the primary end point was disease-free survival. RESULTS: From a total sample of 247 patients, 14 withdrew, leaving 112 in the control arm and 121 in the experimental arm. In 15 control subjects (13%), completion ALND was positive, with a low tumor burden. Four patients experienced disease recurrence: 1 (1%) of 108 control subjects and 3 (2.5%) of 119 experimental patients. There were no differences in disease-free survival (p=0.325) between arms and no cancer-related deaths. CONCLUSIONS: Our results strongly suggest that in early breast cancer patients with SN micrometastasis, selective SN lymphadenectomy suffices to control locoregional and distant disease, with no significant effects on survival.

[Oncologic risk counselling unit. Selection of risk groups and results]. / Consulta de riesgo oncológico. Selección de grupos de riesgo y resultados.

BACKGROUND AND OBJECTIVE: We evaluated the patients' selection and the results of the detection of mutations as well as the follow-up of families at a genetic counselling unit. PATIENTS AND METHOD: One hundred and fifty three patients were visited corresponding to 137 families: 77 of them were classified as high-risk group, 35 as moderate-risk and 25 as low-risk. The classification of patients in each group was made according to the recommendations of the guidelines and the "Oncoguia de càncer familiar" of the Departament de Salut de la Generalitat de Catalunya. RESULTS: With regard to familiar antecedents, patients of the high-risk group had an average (standard deviation) of 2.80 (1.5) cases of breast and/or ovarian cancer, while it was 1.82 (0.75) in the moderate-risk group, and 1.05 (0.80) in the low-risk group. Thirty seven families of high-risk (51.9%) were studied for the detection of deleterious mutations in BRCA1/2. Of 37 completed studies, 5 were positive (one BRCA1 and one BRCA2), 3 had variants of unknown significance in BRCA2 and 25 (83.4%) had no deleterious mutation in BRCA1/2. CONCLUSIONS: A correct selection of patients was performed, because 16.6% of BRCA's studies was positive. This fact allows us to adapt a planning of screening.

Ovulation induction treatment and risk of borderline ovarian tumors.

AIM: Research has suggested an association between the use of ovulation induction drugs and the risk of ovarian cancer. It has also been proposed that there may be pre-cancerous alterations in the ovary which themselves are the cause of infertility. The aim of the present study was to evaluate the relationship between the use of ovulation induction drugs and the appearance of borderline ovarian tumors. MATERIAL AND METHODS: This was a case-control study in which the study group comprised 42 women with a borderline ovarian tumor and the control group comprised 257 women with benign ovarian pathology. RESULTS: No differences were found between the borderline tumor and control groups (14.3% vs. 27.2%, respectively) in terms of infertility history. Nor were there any differences between the groups with respect to the type of drug used, whether clomiphene citrate (9.5% vs. 6.2%, respectively) or gonadotropins (7.1% vs. 10.1%, respectively). Analysis in terms of the number of cycles administered also failed to reveal any differences. The mean number of cycles with clomiphene citrate/gonadotropins was 2.50 +/- 1.00 and 3.00 +/- 2.64 in the borderline tumor group and 2.44 +/- 1.75 and 3.27 +/- 2.25 in the control group. CONCLUSIONS: Our series produced no evidence that ovulation induction treatment predisposes women to the development of borderline ovarian tumors.

Tumor size and lymph node status in multifocal breast cancer.

Tumor size correlates with lymph node metastasis in breast cancer. In multifocal lesions there is controversy about considering the summation of the largest diameter of each tumor. A total of 122 patients with multifocal breast cancer were compared in a retrospective study with 177 patients with unifocal tumors, correlating tumor size with lymph node metastasis. In multifocal tumors, two sizes were considered: the diameter of the largest tumor and the combined diameter of all lesions. Relationship was established by three different logistic models using variables such as age, number of lesions, histologic type, and grade. At a same size of the largest diameter of a unifocal or multifocal lesions and the combined diameter of a multifocal lesion, the latter shows less probability of nodal metastasis indicating that combined diameter is an overestimation of the lesion size. Our results indicate that in multifocal breast cancer, only the diameter of the largest tumor breast cancer has relationship with lymph node metastasis.

Correlación entre ploidia y fase S, y características morfológicas y receptores hormonales en el cáncer de mama: estudio de 402 casos / Correlation between ploidy and S phase faction and morphological characteristic and hormonal recepyor in breast cancer: study of 402 cases

Con la finalidad de establecer la relación entre ploidia, fase S y las características morfológicas del carcinoma de mama se estudiaron 402 muestras de material en fresco. No se encontro ninguna relación entre ploidia y fase S, y el status de los ganglios linfáticos y la edad de los pacientes. Las lesiones aneuploides resultaron de mayor tamaño que los tumores diploides y usualmente no expresaban receptores hormonales. Los carcinomas ductales infiltrantes (322/402) mostraron mayor porcentaje de lesiones aneuploides y una fase S más elevada en relación con el incremento del grado histológico, la formación de túbulos, el pleomorfismo nuclear y el índice mitótico. En el análisis multivariante, el plemorfismo nuclear y el tamaño tumoral constituyeron las únicas variables independientes y con valor de predicción para la aneuploidia. El patrón de ADN y la fase S constituyen variables que se correlacionan con los cambios morfológicos y así proporcionan información objetiva y reproducible
