- Background Quinquennial overviews (1985-2000) of the randomised trials in early breast cancer have assessed the 5-year and 10-year effects of various systemic adjuvant therapies on breast cancer recurrence and survival. Here, we report the 10-year and 15-year effects. Methods Collaborative meta-analyses were undertaken of 194 unconfounded randomised trials of adjuvant chemotherapy or hormonal therapy that began by 1995. Many trials involved CMF (cyclophosphamide, methotrexate, fluorouracil), anthracycline-based combinations such as FAC (fluorouracil, doxombicin, cyclophosphamide) or FEC (fluorouracil, epirubicin, cyclophosphamide), tamoxifen, or ovarian suppression: none involved taxanes, trastuzumab, raloxifene, or modem aromatase inhibitors. Findings Allocation to about 6 months of anthracycline-based polychemotherapy (eg, with FAC or FEC) reduces the annual breast cancer death rate by about 38% (SE 5) for women younger than 50 years of age when diagnosed and by about 20% (SE 4) for those of age 50-69 years when diagnosed, largely irrespective of the use of tamoxifen and of oestrogen receptor (ER) status, nodal status, or other tumour characteristics. Such regimens are significantly (2p=0 . 0001 for recurrence, 2p<0 . 00001 for breast cancer mortality) more effective than CMF chemotherapy. Few women of age 70 years or older entered these chemotherapy trials. For ER-positive disease only, allocation to about 5 years of adjuvant tamoxifen reduces the annual breast cancer death rate by 31% (SE 3), largely irrespective of the use of chemotherapy and of age (<50, 50-69, &GE; 70 years), progesterone receptor status, or other tumour characteristics. 5 years is significantly (2p<0 . 00001 for recurrence, 2p=0 . 01 for breast cancer mortality) more effective than just 1-2 years of tamoxifen. For ER-positive tumours, the annual breast cancer mortality rates are similar during years 0-4 and 5-14, as are the proportional reductions in them by 5 years of tamoxifen, so the cumulative reduction in mortality is more than twice as big at 15 years as at 5 years after diagnosis. These results combine six meta-analyses: anthracycline-based versus no chemotherapy (8000 women); CMF-based versus no chemotherapy (14 000); anthracycline-based versus CMF-based chemotherapy (14 000); about 5 years of tamoxifen versus none (15 000); about 1-2 years of tamoxifen versus none (33 000); and about 5 years versus 1-2 years of tamoxifen (18 000). Finally, allocation to ovarian ablation or suppression (8000 women) also significantly reduces breast cancer mortality, but appears to do so only in the absence of other systemic treatments. For middle-aged women with ER-positive disease (the commonest type of breast cancer), the breast cancer mortality rate throughout the next 15 years would be approximately halved by 6 months of anthracycline-based chemotherapy (with a combination such as FAC or FEC) followed by 5 years of adjuvant tamoxifen. For, if mortality reductions of 38% (age <50 years) and 20% (age 50-69 years) from such chemotherapy were followed by a further reduction of 31% from tamoxifen in the risks that remain, the final mortality reductions would be 57% and 45%, respectively (and, the trial results could well have been somewhat stronger if there had been full compliance with the allocated treatments). Overall survival would be comparably improved, since these treatments have relatively small effects on mortality from the aggregate of all other causes. Interpretation Some of the widely practicable adjuvant drug treatments that were being tested in the 1980s, which substantially reduced 5-year recurrence rates (but had somewhat less effect on 5-year mortality rates), also substantially reduce 15-year mortality rates. Further improvements in long-term survival could well be available from newer drugs, or better use of older drugs.

- Glioblastoma multiforme (GBM) is a malignant CNS tumor with a poor prognosis. GBM shows aberrant glycosylation with hypersialylation. This property is a potential target for therapy. This study investigates the growth inhibitory efficacy of poly-guanidine (GuaDex), with an affinity for sialic acid (Sia). Glioma cell cultures and patient-derived glioma cell lines (PDGCLs) expressing Prominin-1 (CD133) were used. Human fibroblasts and astrocyte-derived cells were used as controls. Temozolomide (standard GBM drug, TMZ) and DMSO were used as a comparison. GuaDex at 1–10 µM concentrations, were incubated for 3.5–72 h and with PDGCLs cells for 6–24 h. The cytotoxicity was estimated with a fluorometric cytotoxicity assay (FMCA). Fluorescence-labelled GuaDex was used to study the cell interactions. Sia expression was confirmed with a fluorescence labelled Sia binding lectin. Expression of glial fibrillary acidic protein was determined. GuaDex induction of growth inhibition was fast, showing after less than 5 min incubation while the control cells were not affected even after 50 min incubation. The growth inhibitory effect on PDGCLs spheroids was persistent still showing after 4 weeks post-treatment. The growth inhibition of GuaDex was induced at low µM concentrations while TMZ induced only a slight inhibition at mM concentrations. GuaDex efficacy appears significant and warrants further studies.

- 236 Background: A cytostatic polybisphosphonate was developed for Tx of mCRPC. It has a) anti-resorptive effects, osteoclast inhib., b) tum. cell spec./tox, confirmed in in-vivo models. Tox. study shows high tolerability. Animal PK study has shown T½ < 3 hrs; principal accumulation in liver, spleen, kidneys. Methods: Clin phase I/IIa (clinicaltrials.gov NCT01595087): Prim obj: to define MTD of ODX given every 3rd week. Sec. obj: OS, bone metab. and resp. markers, PSA, QoL and PK. Explorative in vitrostudies (basis for rand. phase IIb trial in pts. with docetax-res. mCRPC). A docetax-resist. cell-line was developed from DU145 in escalating conc. of docetax, then continuous growth in docetax 500 µg/ml. Cells subj. to cytotox. exp. with ODX (iCELLigence system and fluorom microculture cytotox assay). Results: Clin Phase I/IIa first-in-man trial (clinicaltrials.gov NCT01595087): 17/28 patients rec. 4-7 doses every 3rd week. No DLTs; max dose adm.: 3.0 mg/kg: no drug-related SAEs. Tx was well tolerated. Efficacy and QoL data w. considerable variability as to be expected in this population of pts. w. mCRPC. Max blood conc. ODX: 110-160 fmol/mL; 85-90 % cleared within first 1 hr. Efficacy of ODX in docetax-res DU145TR: A dose-dependent cytotox effect seen when adding ODX in “sub-clin.” doses. All cells were apparently killed in the clin. relevant dose 6 uM. Conclusions: ODX is a novel drug cand. w. high cytotox. efficacy in vivo and in vitro, even in highly docetax-res. cells. Animal studies and Phase I trial show excellent tolerability. Studies now ongoing to elucidate whether short-term treatment is as efficacious as continuous treatment and whether some cells de facto may develop resistance also to this new treatment concept. A multicenter rand. double-blind pbo. controlled trial (EudraCT 2014-002054-39) starts Q4 2014 in mCRPC pts failing docetax and/or cabazitaxel AND abiraterone and/or enzalutamide. Clinical trial information: NCT01595087.
