    Abstract: Patients with isolated distal deep vein thrombosis (DVT) have lower rates of adverse outcomes (death, venous thromboembolism [VTE] recurrence or major bleeding) than those with proximal DVT. It is uncertain if such findings are also observed in patients with cancer. METHODS Using data from the international Registro Informatizado de la Enfermedad TromboEmbolica venosa registry, we compared the risks of adverse outcomes at 90 days (adjusted odds ratio [aOR]; 95% CI) and 1 year (adjusted hazard ratio [aHR; 95% CI] ) in 886 patients with cancer-associated distal DVT versus 5,196 patients with cancer-associated proximal DVT and 5,974 patients with non–cancer-associated distal DVT. RESULTS More than 90% of patients in each group were treated with anticoagulants for at least 90 days. At 90 days, the adjusted risks of death, VTE recurrence, or major bleeding were lower in patients with non–cancer-associated distal DVT than in patients with cancer-associated distal DVT (reference): aOR = 0.16 (0.11-0.22), aOR = 0.34 (0.22-0.54), and aOR = 0.47 (0.27-0.80), respectively. The results were similar at 1-year follow-up: aHR = 0.12 (0.09-0.15), aHR = 0.39 (0.28-0.55), and aHR = 0.51 (0.32-0.82), respectively. Risks of death, VTE recurrence, and major bleeding were not statistically different between patients with cancer-associated proximal versus distal DVT, both at 90 days: aOR = 1.11 (0.91-1.36), aOR = 1.10 (0.76-1.62), and aOR = 1.18 (0.76-1.83), respectively, and 1 year: aHR = 1.01 (0.89-1.15), aHR = 1.02 (0.76-1.35), and aHR = 1.10 (0.76-1.61), respectively. However, more patients with cancer-associated proximal DVT, compared with cancer-associated distal DVT, developed fatal pulmonary embolism (PE) during follow-up: The risk difference was 0.40% (95% CI, 0.23 to 0.58). CONCLUSION Cancer-associated distal DVT has serious and relatively comparable outcomes compared with cancer-associated proximal DVT. The lower risk of fatal PE from cancer-associated distal DVT needs further investigation.

    Abstract: 264 Background: Abiraterone (Abi), enzalutamide (Enza) and docetaxel (Doc) are all valid first-line (1L) mCRPC treatment options. Evidence suggests a degree of cross-resistance between agents, which may impact the efficacy of subsequent lines of therapy. Evidence on the optimal treatment sequence is lacking. Methods: We evaluated the outcome of patients (pts) treated with 1L Doc, Abi or Enza in the prospective PROREPAIR-B cohort study. We assessed the impact of 1L treatment option (Doc vs Abi/Enza) on overall survival (OS), progression-free survival (PFS) to 1L-therapy (PCWG2) and PFS2 (time from initiation of 1L-therapy to progression on second-line [2L] therapy). Uni- (UV) and multivariable (MV) cox-regression models were used. MV model covariates included age (≥75 years), local therapy, Gleason Score, metastases at diagnosis, visceral metastases, ALP (≥ULN), LDH (≥ULN), haemoglobin (≤LNL), albumin (≤LNL) and ECOG PS. Results: 406 pts received 1L-Doce (N=188) or Abi/Enza (N=218). Pts receiving Doc were younger (p=0.002), had higher rates of visceral metastases (17.6 vs 8.7%; p=0.008), ALP (52.1% vs 40.4%; p=0.018), LDH (48.1% vs 31.2%; p 〈 0.001) and lower Hb (7.4 vs 2.8%; p=0.029) and albumin (11.3 vs 4.6%). PFS was higher in pts receiving 1L-Abi/Enza (10.8 vs 8.3 months; HR:0.5; p 〈 0.001). Pts receiving 1L Abi/Enza had higher rates of radiographic progression (88.4 vs 80%; p=0.032). 123/188 pts treated with 1L-Doc received 2L-Abi/Enza: 30 received other 2L and 35 had not started 2L. 111/216 pts treated with 1L-Abi/Enza received 2L-Doc, 26 were started on other 2L and 79 had not initiated 2L. A significant difference between pts treated with initial Abi/Enza vs Doc was observed in PFS2 (20.6 vs 16.6m; HR:0.78; p=0.006) but not OS (31.3 vs 29.9 m; HR:1.05; p=0.725). Choice of first-line agent was not associated with OS in the MV model. Conclusions: Despite longer PFS to 1L and PFS2 in pts treated with initial Abi/Enza, no differences in OS were observed between treatment sequences starting with Doc vs Abi/Enza. Pts treated with 1L-Doc had worse baseline prognostic features. Molecular stratification may enable biomarker-driven patient selection to optimize benefit in pts. (NCT03075735).

    Correlation between time to PSA progression (TTPP), radiographic progression-free survival (rPFS) and overall survival (OS) in first-line abiraterone/enzalutamide (Abi/Enza) and docetaxel (Doc) treated patients in a prospective cohort study.

    Abstract: 267 Background: Abiraterone, enzalutamide and docetaxel represent first-line (1L) treatment options in mCRPC. A significant correlation between rPFS and OS has been reported for patients treated with 1L abi and enza in mCRPC. It is however unclear whether TTPP or rPFS present a similar magnitude of correlation with OS in Doc-treated pts. Methods: We evaluated the association of TTPP and rPFS with OS in pts treated with 1L Abi/Enza or Doc in a prospective multicenter observational cohort study. TTPP and rPFS were defined as per PCWG2. Correlation between TTPP and rPFS with OS was evaluated with Spearman rho coefficients (r), and by calculating the concordance index (c-index) in Cox-regression models. Results: 406 out of 419 pts received 1L Abi/Enza or Doc. After a median follow-up of 40 months (m), 253 mCRPC-related deaths were observed, with a median OS of 31.3 m (95% CI: 27.6-35). Median rPFS and TTPP were 10.8 m (95% CI:9.7-11.9) and 7.2 m (95% CI:6.7-7.7), respectively. Significant correlations between rPFS/TTPP and OS were observed in all pts treated at 1L, as well as in Abi/Enza and Doc treated pts (Table). R and c-index were consistently higher in Abi/Enza treated pts than in Doc treated pts, with a higher difference in predictive accuracy of the Cox regression model observed when comparing the association between TTPP and OS (c-index 0.788 in Abi/Enza treated pts vs 0.627 in Doc treated pts). Conclusions: Differences in r and c-index were observed when evaluating the association between TTPP/rPFS and OS in Abi/Enza and Doc treated pts, suggesting rPFS and TTPP may better predict OS in Abi/Enza than in Doc-treated pts. Indirect comparisons of TTPP in Abi/Enza vs Doc pts may therefore not reflect their true impact on OS. Further insight on the exact significance of TTPP is needed.
