OAPS shows differential characteristics than classical APS. All laboratory test categories are needed to avoid false-negative diagnoses. In some cases, complement levels could act as a serological marker. OAPS has very good foetal-maternal outcomes when treated. Thrombosis and progression to SLE in mothers with OAPS are scarce compared with "classical APS", suggesting that they have different aPL-mediated pathogenic mechanisms.

Maternal age over 40 years is an independent risk factor for adverse pregnancy outcomes, particularly for the mother. Pregnancies in women over 40 years should be considered at risk and carefully monitored with individualized care protocols.

501 Background: 1-year trastuzumab with chemotherapy is the standard adjuvant treatment for HER2+ breast cancer patients (pts). The efficacy of less extended trastuzumab exposure is still under investigation. The Short-HER study is an independent, non-profit study aimed to test the non-inferiority of 9 weeks vs 1 year of adjuvant trastuzumab. Methods: This is a phase III, multicenter, Italian trial where pts with HER2+ breast cancer were randomly assigned to: Arm A (Long) AC or ECx4 followed by 4 courses of 3-weekly docetaxel in combination with trastuzumab, followed by 14 additional courses of 3-weekly trastuzumab; or Arm B (Short) 3 courses of 3-weekly docetaxel plus weekly trastuzumab for 9 doses followed by FEC x3. When indicated, radiation therapy was administered after the completion of chemotherapy. Hormonal therapy started at the completion of chemotherapy for pts with hormone receptor positive tumors. This is a non-inferiority trial with disease-free survival (DFS) as primary end-point.Overall survival (OS) is evaluated as second primary analysis outcome. The sample size of 1250 pts has been estimated based on a hazard ratio <1.29 for the short arm to be non-inferior. The definitive analysis will take place after 198 DFS events. Secondary aims include 2-yrs failure rate, cardiac toxicity, correlative biomarkers analyses. Hazard ratio for DFS and OS (90% CI) will be estimated according to the Cox model. Data will also be analyzed by the Bayesian approach. Results: from Dec-2007 to Oct-2013, 1254 pts from 82 centers have been randomized. Pts characteristics are the following: median age 55 yrs (25-78), stage I 37.3%, IIA 40%, IIB 20.6%, III 2.1%. 30% of the pts had 1-3 positive nodes, 16% >=4. Sixty-eight% of the pts had ER+ tumors. Characteristics were balanced between the two arms. At the time of this writing, 95% of the planned DFS events have been reported. 105 Grade ≥2 cardiac events have been reported, 78 in arm A (long) and 27 in arm B (short). Grade 3-4 cardiac events were 20 in arm A and 11 in arm B. Conclusions: Shorter trastuzumab administration almost halves the rate of severe cardiac toxicity. Final DFS data will be available at the time of the meeting. Clinical trial information: NCT00629278.

Women with headache should be considered at risk for adverse perinatal outcomes and should, therefore, be included in a high-risk pregnancy protocol of care throughout pregnancy.

Insulin-like growth factor-II (IGF-II) may be a prognostic marker in ovarian cancer, and its intronic single nucleotide polymorphism (SNP) rs4320932 has been associated with risk of the disease. We determined whether rs4320932 is associated with IGF-II expression and patient survival in ovarian cancer, and explored whether the SNP variation affects DNA conformation both in the absence of and presence of carboplatin. IGF-II genotype (rs4320932) and phenotype were analyzed in 212 primary invasive epithelial ovarian cancer tissue samples with Taqman® SNP genotyping assays, quantitative reverse transcription-polymerase chain reaction and commercial enzyme-linked immunosorbent assay. DNA conformation was evaluated by circular dichroism (CD) spectra. Kaplan-Meier survival curves and Cox proportional hazard regression models were used to analyze the SNP associations with patient survival. The C allele of rs4320932, previously associated with decreased risk of ovarian cancer development, was here associated with significantly elevated risks of relapse (Ptrend = 0.0002) and death (Ptrend = 0.0006), remaining significant in multivariate analyses. The adjusted hazard ratios were 3.05 (95% confidence interval [CI]: 1.47-6.37) for relapse and 3.28 (95% CI: 1.64-6.57) for death, respectively. The variant was also significantly associated with chemotherapy response, but not with other clinicopathologic variables or with IGF-II expression. DNA with genotypes TT and CC had distinct CD spectra in both the absence of and presence of carboplatin. These findings suggest that the intronic SNP rs4320932 affects patient survival and chemotherapy response via alteration of DNA conformation, but not through regulation of IGF-II expression. This novel finding may have implications in individualized medicine for the design of specific molecules targeting DNA of specific conformations.
