The creation of new blood vessels from existing ones, which is a mechanism called “angiogenesis”, is essential in cancer to supply cancerous growth. Moreover, the development and the progression of the tumor and its metastases are the result of an efficient vascular response. Cancer cells release and activate different angiogenic growth factors and their receptors in the tumor microenvironment to promote the angiogenic process. The most important pro-angiogenic factor is the “Vascular Endothelial Growth Factor” (VEGF) because of its mitogen activity on vascular endothelium. Bevacizumab is a monoclonal antibody that obstructs the binding of circulating vascular endothelial growth factor to its receptors and has been approved for the treatment of primary and recurrent ovarian cancer but also for many other solid tumors.

We describe two cases of uterine rupture in pregnancy after laparoscopic myomectomy and analyze all the aetiological factors involved in this circumstance according to the recent literature, focusing above all on the surgical procedures and the characteristics of the excised myomas. The two cases of uterine rupture in pregnancy following laparoscopic myomectomy occurred at 36 and 18 weeks of gestation, respectively. Both women had undergone laparoscopic multiple myomectomy and uterine rupture occurred along the isthmic myomectomy scars, despite the fact that compliance with all the recent technical surgical recommendations for the previous laparoscopic multiple myomectomy had been fully observed. In our cases we identified the isthmic localization, size of the excised myomas (≥4 cm), and individual characteristics of the healing process as possible risk factors for “a real complication.” Larger studies and robust case‐control analyses are needed to draw reliable conclusions; special care should be paid when performing laparoscopic myomectomy in women planning a later pregnancy.
BRCA1/2 are tumour-suppressor genes involved in DNA homologous recombination and ovarian cancer development. The study evaluated the risk of tumor cancer in women presenting the BRCA mutations. Risk-reducing surgery (RRS) was performed in 100 patients carrying BRCA1 (aged between 30-73 years, median age was 51 years) and BRCA 2 mutation (aged between 36-70 years, median age was 53 years). Fifty-eight patients had previous history of breast cancer. Between the 100 patients, 82 women underwent risk-reducing salpingo-oophorectomy (RRSO) through a laparoscopic minimally invasive approach, 7 (7 %) underwent laparoscopic RRSO and contextual hysterectomy, 1 woman (1 %) underwent RRSO through a laparotomic approach and 10 women (10 %) laparotomic RRSO and hysterectomy. During 5 (5 %) laparoscopic RRSO, prophylactic bilateral mastectomy was also performed. Early and late complication occurred in 3 patients (3 %). Two patients (2 %) were found to have occult Serous Tubal Intraepithelial Carcinoma (STIC) and three patients (3 %) occult cancer. RRSO is safe and feasible in BRCA mutation carriers. The procedure is effective for genetic prevention of ovarian cancer.
This study evaluates the efficacy and toxicity of dose-dense weekly paclitaxel and carboplatin as neoadjuvant chemotherapy in locally advanced cervical cancer (LACC). We collected 23 cases of LACC treated with weekly paclitaxel and carboplatin for nine cycles: 20 patients had complete or partial response to chemotherapy and were submitted to surgery, 3 with poor response received chemoradiation therapy. Pathologic examination showed complete response in four patients, myometrial invasion 50% in seven patients, parametrial involvement in two, vaginal metastasis in one and lymphovascular space invasion, with positive margins, in another case. Despite seven patients had radiological evidence of lymph nodes involvement at diagnosis, only one had nodal metastases. Five patients showed grade 3–4 of hematologic toxicity.

Background: To evaluate the clinical and pathologic factors associated with survival in patients with advanced staged endometrial carcinoma. Matreials and Methods: Between 2005 and 2017 all patients with endometrial carcinoma type I were identified from tumor registry databases at this Academic hospital. The impact of clinical and pathologic risk factors on the survival of patients with endometrial carcinoma was evaluated using Kaplan-Meier life table analyses and log-rank tests. Results: Forty-nine patients with advanced endometrial cancer were collected. The median progression-free survival (PFS) for all patients was 42 months whereas the median overall survival (OS) was 69 months for all patients. Univariate analysis was extended to all prognostic factors for all stages showed as statistically significant positive cytology and cervical invasion, whereas for Stage III only cervical invasion. For Stage IIIA the prognostic factors statistically significant were cervical invasion and lymphovascular space invasion (LVSI). Furthermore, prognosis was worse in tumors belonging to Stage IV with positive cytology. Conclusion: Prognostic factors related to a lower survival rate in advanced stages of endometrial cancer are represented by cervical invasion, LVSI, and positive peritoneal cytology. These factors with respect to LVSI and positive peritoneal cytology should be included in FIGO 2009 surgical staging system because associated to a poor prognosis.
