- Background: To examine the effect on cognitive function of adjuvant ovarian function suppression (OFS) for breast cancer. Methods: The Suppression of Ovarian Function (SOFT) trial randomised premenopausal women with hormone receptor-positive breast cancer to 5 years adjuvant endocrine therapy with tamoxifen + OFS, exemestane + OFS or tamoxifen alone. The Co-SOFT substudy assessed objective cognitive function and patient reported outcomes at randomisation (T0), and 1 year later (T1); the primary endpoint was change in global cognitive function, measured by the composite objective cognitive function score. Data were compared for the pooled tamoxifen + OFS and exemestane + OFS groups vs the tamoxifen alone group using the Wilcoxon rank-sum test. Results: Of 86 participants, 74 underwent both T0 and T1 cognitive testing; 54 randomised to OFS+ either tamoxifen (28) or exemestane (26) and 20 randomised to tamoxifen alone. There was no significant difference in the changes in the composite cognitive function scores between the OFS+ tamoxifen or exemestane groups and the tamoxifen group (mean +/- s.d., -0.21 +/- 0.92 vs -0.04 +/- 0.49, respectively, P = 0.71, effect size = -0.20), regardless of prior chemotherapy status, and adjusting for baseline characteristics. Conclusions: The Co-SOFT study, although limited by small samples size, provides no evidence that adding OFS to adjuvant oral endocrine therapy substantially affects global cognitive function.

- Late recurrences in postmenopausal women with hormone receptor-positive breast cancers remain an important challenge. Avoidance or delayed development of resistance represents the main objective in extended endocrine therapy. In animal models, resistance was reversed with restoration of circulating estrogen level during interruption of letrozole treatment. This phase 3 randomized, open-label Study of Letrozole Extension (SOLE) studied the effect of extended intermittent letrozole treatment in comparison with continuous letrozole. In parallel, the SOLE estrogen sub-study (SOLE-EST) analyzed the level of estrogen during the interruption of treatment.SOLE enrolled 4884 postmenopausal women with hormone receptor-positive, lymph node-positive, operable breast cancer between December 2007 and October 2012 and among them, 104 patients were enrolled in SOLE-EST. They must have undergone local treatment and have completed 4-6 years of adjuvant endocrine therapy. Patients were randomized between continuous letrozole (2.5 mg/day orally for 5 years) and intermittent letrozole treatment (2.5 mg/day during 9 months followed by a 3-month interruption in years 1-4 and then 2.5 mg/day during all year 5).Intention-to-treat population included 4851 women in SOLE (n=2425 in intermittent and n=2426 in continuous letrozole groups) and 103 women in SOLE-EST (n=78 in intermittent and n=25 in continuous letrozole groups). After a median follow-up of 84 months, 7-year disease-free survival was 81.4% in intermittent group and 81.5% in continuous group (hazard ratio: 1.03, 95%CI: 0.91-1.17). Reported adverse events were similar in both groups. Circulating estrogen recovery was demonstrated within 6 weeks after the stop of letrozole treatment.Extended adjuvant endocrine therapy by intermittent administration of letrozole did not improve disease-free survival compared to continuous use despite the recovery of circulating estrogen level. The similar disease-free survival coupled with previously reported quality-of-life advantages suggest intermittent extended treatment is a valid option for patients who require or prefer a treatment interruption.

- The relative phase of first (omega(1)) and third harmonics (omega(3)) extreme ultraviolet light pulses was varied to control the population of the 2s(2) state in helium through the interference of omega(1) + omega(1) and omega(3) - omega(1) two-photon excitation paths. The population was monitored by observing the total electron yield due to the 2s(2) autoionization decay. Maximum yield occurs when the relative phase of the two harmonics matches the phase difference of complex atomic amplitudes governing the two excitation paths. The calculated trend of atomic phase differences agrees well with the measured data in the spectral region of the resonance, provided that time-reversed -omega(1) + omega(3) path is also taken into account. These results open the way to accessing phase differences of two-photon ionization paths involving energetically distant intermediate states and to perform interferometry in the extreme ultraviolet range by monitoring final state populations.
