    Several improvements in ovarian cancer treatment have been achieved in recent years, both in surgery and in combination chemotherapy with targeting. However, ovarian tumors remain the women's cancers with highest mortality rates. In this scenario, a pivotal role has been endorsed to the immunological environment and to the immunological mechanisms involved in ovarian cancer behavior. Recent evidence suggests a loss of the critical balance between immune-activating and immune-suppressing mechanisms when oncogenesis and cancer progression occur. Ovarian cancer generates a mechanism to escape the immune system by producing a highly suppressive environment. Immune-activated tumor infiltrating lymphocytes (TILs) in ovarian tumor tissue testify that the immune system is the trigger in this neoplasm. The TIL mileau has been demonstrated to be associated with better prognosis, more chemosensitivity, and more cases of optimal residual tumor achieved during primary cytoreduction. Nowadays, scientists are focusing attention on new immunologically effective tumor biomarkers in order to optimize selection of patients for recruitment in clinical trials and to identify relationships of these biomarkers with responses to immunotherapeutics. Assessing this point of view, TILs might be considered as a potent predictive immunotherapy biomarker

    Objectives To report the outcome of pregnancies complicated by twin–twin transfusion syndrome (TTTS) according to Quintero stage. Methods MEDLINE, EMBASE and CINAHL databases were searched for studies reporting the outcome of pregnancies complicated by TTTS stratified according to Quintero stage (I–V). The primary outcome was fetal survival rate according to Quintero stage. Secondary outcomes were gestational age at birth, preterm birth (PTB) before 34, 32 and 28 weeks' gestation and neonatal morbidity. Outcomes are reported according to the different management options (expectant management, laser therapy or amnioreduction) for pregnancies with Stage‐I TTTS. Only cases treated with laser therapy were considered for those with Stages‐II–IV TTTS and only cases managed expectantly were considered for those with Stage‐V TTTS. Random‐effects head‐to‐head meta‐analysis was used to analyze the extracted data. Results Twenty‐six studies (2699 twin pregnancies) were included. Overall, 610 (22.6%) pregnancies were diagnosed with Quintero stage‐I TTTS, 692 (25.6%) were Stage II, 1146 (42.5%) were Stage III, 247 (9.2%) were Stage IV and four (0.1%) were Stage V. Survival of at least one twin occurred in 86.9% (95% CI, 84.0–89.7%) (456/552) of pregnancies with Stage‐I, in 85% (95% CI, 79.1–90.1%) (514/590) of those with Stage‐II, in 81.5% (95% CI, 76.6–86.0%) (875/1040) of those with Stage‐III, in 82.8% (95% CI, 73.6–90.4%) (172/205) of those with Stage‐IV and in 54.6% (95% CI, 24.8–82.6%) (5/9) of those with Stage‐V TTTS. The rate of a pregnancy with no survivor was 11.8% (95% CI, 8.4–15.8%) (69/564) in those with Stage‐I, 15.0% (95% CI, 9.9–20.9%) (76/590) in those with Stage‐II, 18.6% (95% CI, 14.2–23.4%) (165/1040) in those with Stage‐III, 17.2% (95% CI, 9.6–26.4%) (33/205) in those with Stage‐IV and in 45.4% (95% CI, 17.4–75.2%) (4/9) in those with Stage‐V TTTS. Gestational age at birth was similar in pregnancies with Stages‐I–III TTTS, and gradually decreased in those with Stages‐IV and ‐V TTTS. Overall, the incidence of PTB and neonatal morbidity increased as the severity of TTTS increased, but data on these two outcomes were limited by the small sample size of the included studies. When stratifying the analysis of pregnancies with Stage‐I TTTS according to the type of intervention, the rate of fetal survival of at least one twin was 84.9% (95% CI, 70.4–95.1%) (94/112) in cases managed expectantly, 86.7% (95% CI, 82.6–90.4%) (249/285) in those undergoing laser therapy and 92.2% (95% CI, 84.2–97.6%) (56/60) in those after amnioreduction, while the rate of double survival was 67.9% (95% CI, 57.0–77.9%) (73/108), 69.7% (95% CI, 61.6–77.1%) (203/285) and 80.8% (95% CI, 62.0–94.2%) (49/60), respectively. Conclusions Overall survival in monochorionic diamniotic pregnancies affected by TTTS is higher for earlier Quintero stages (I and II), but fetal survival rates are moderately high even in those with Stage‐III or ‐IV TTTS when treated with laser therapy. Gestational age at birth was similar in pregnancies with Stages‐I–III TTTS, and gradually decreased in those with Stages‐IV and ‐V TTTS treated with laser and expectant management, respectively. In pregnancies affected by Stage‐I TTTS, amnioreduction was associated with slightly higher survival compared with laser therapy and expectant management, although these findings may be confirmed only by future head‐to‐head randomized trials

    Effect of Surgery for Endometrioma on Ovarian Function: A Different Point of View

    No full text
    Recent evidence in the literature suggests that surgical excision of the endometrioma wall may reduce ovarian reserve, which may have a negative effect on subsequent reproductive function. However, because of inconsistent results and methodologic flaws of anti-müllerian hormone (AMH) as a marker of ovarian reserve, antral follicle count may be a more accurate noninvasive marker than AMH. Evaluating ovarian reserve using antral follicle count rather than AMH may yield different conclusions insofar as postsurgical damage to the ovary. Surgery should be performed only by experienced surgeons, and the stripping technique currently is still the only one supported by strong scientific evidence. The dual function of surgery, that is, to improve fertility and reduce pain, cannot be minimized or undervalued

    Salpingoscopy during laparoscopy using a small-caliber hysteroscope introduced through an accessory trocar.

    Salpingoscopy is an endoscopic technique that allows the direct visualization of the tubal mucosa. The status of the tubal mucosa is the best prognostic factor when evaluating patients with tubal infertility. Salpingoscopy, performed during laparoscopy, has not reached wide acceptance due the costly, non-user-friendly, dedicated instrumentation needed. In this article, a simplified technique to perform salpingoscopy at the time of laparoscopy is reported, using a standard 2.9-mm diagnostic hysteroscope, with a 3.7-mm single-flow diagnostic sheath, introduced through an accessory port. Salpingoscopy, with this new technique, was performed in 13 patients with tubal infertility. The tubes were successfully cannulated in all patients, for a total of 24 tubes evaluated (2 patients had a single tube). Salpingoneostomy and salpingoovarolysis were completed after salpingoscopy only when the tubal mucosa was normal. In 1 patient with severe tubal damage, salpingectomy of the single remaining tube was performed. Salpingoscopy added a mean of 15 minutes to surgical time. Intrauterine pregnancies were obtained, after salpingoneostomy, fimbrioplasty, or adhesiolysis, in 5 of 12 patients (42%), with a mean follow-up of 9 months. The simplified technique of salpingoscopy, with a diagnostic hysteroscope introduced through an accessory trocar at the time of laparoscopy, adds important information on the reproductive potential of patients with tubal disease
