Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide. There is an urgent need to identify prognostic markers for patients undergoing curative resection of CRC. The detection of circulating tumor cells in peripheral blood is a promising approach to identify high-risk patients with disseminated disease in colorectal cancer. This study aims to evaluate the prognostic relevance of preoperative CTCs using the Cellsearch® system (CS) in patients, who underwent resection with curative intent of different stages (UICC I-IV) of colorectal cancer. Out of 91 Patients who underwent colorectal resection, 68 patients were included in this study. CTC analysis was performed in patients with CRC UICC stages I-IV immediately before surgery. Data were correlated with clinicopathological parameters and patient outcomes. One or more CTCs/7.5 mL were detected in 45.6% (31/68) of patients. CTCs were detected in all stages of the Union of International Cancer Control (UICC), in stage I (1/4, 25%), in stage II (4/12, 33.3%), in stage III (5/19, 26.3%) and in stage IV (21/33, 63.6%). The detection of ≥ 1 CTCs/ 7.5ml correlated to the presence of distant overt metastases (p = 0.014) as well as with shorter progression-free (p = 0.008) and overall survival (p = 0.008). Multivariate analyses showed that the detection of ≥ 1 CTCs/ 7.5ml is an independent prognostic indicator for overall survival (HR, 3.14; 95% CI, 1.18–8.32; p = 0.021). The detection of CTCs is an independent and strong prognostic factor in CRC, which might improve the identification of high-risk patients in future clinical trials.

ObjectivesTo evaluate the rate of survival and recurrence related to the introduction of pelvic lymphadenectomy in Danish high-risk endometrial cancer patients.Study designData on 713 high-risk patients defined as grade 3 with >50% myometrial invasion or serous/clear/undifferentiated carcinomas stage I–IV endometrial cancer patients diagnosed from 2005 to 2012 were retrieved from the Danish Gynecological Cancer Database. Of these, 305 were high-risk stage I. Five year Kaplan-Meier survival estimates and actuarial recurrence rates were calculated, and adjusted Cox used for comparison. Findings were compared with earlier Danish results.ResultsLymphadenectomy in 390 radically operated high-risk patients resulted in upstaging of 31 patients from stage I to IIIC and 19 patients from stage II to IIIC corresponding to 12.8%. Upstaging from stage I to IIIC had a cancer-specific survival of 77%, almost comparable to lymph node-negative high-risk stage I patients (81%). Lymphadenectomy patients had a significant higher overall survival as compared with non-lymph node resected for all patients, but not for stage I patients. Lymphadenectomy, however, did not significantly affect cancer-specific survival, progression-free survival, recurrence rate or risk of local, distant, or lymph node recurrence. When the survival of high-risk stage I patients was compared with earlier Danish results, a small improvement in overall survival (7%) and cancer-specificsurvival (8%) was demonstrated.ConclusionOnly a small number of high-risk patients were upstaged from stage I to III due to lymphadenectomy. These patients showed a surprisingly good survival possibly due to correct stage identification and subsequent relevant adjuvant therapy. However, even though introduction of lymphadenectomy in the Danish high-risk population seems to increase overall survival, no significant change in cancer-specific survival, progression-free survival or recurrence patterns was demonstrated.

Abstract The detection of CTCs in peripheral blood is one of the most promising approaches to identify disseminated disease in colorectal cancer (CRC). This study aims to evaluate the prognostic relevance of preoperative CTCs using the Cellsearch® system (CS)in patients, who underwent resection with curative intent of different stages of colorectal cancer (UICC I-IV). CTC analysis was performed in 68 CRC patients at UICC stages I-IV immediately before surgery. Data were correlated with clinicopathological parameters and patient outcomes. One or more CTCs/7.5 mL were detected in 45.6% (31/68) of patients. CTCs were detected in all stages of the Union of International Cancer Control (UICC), in stage I (1/4, 25%), in stage II (4/12, 33.3%), in stage III (5/19, 26.3%) in stage IV (21/33, 63.6%).The detection of CTCs was associated to the UICC stage (p = 0.035) and to the presence of distant overt metastases (p = 0.014). The presence of ≥ 1 CTCs/ 7.5 ml correlated significantly with shorter progression-free (p = 0.013) and overall survival (p = 0.014). Multivariate analyses showed that preoperative CTCs are an independent prognostic indicator for overall survival (HR, 2.68; 95% CI, 1.05–6.92 7; p = 0.039, ≥ 1 CTC). In conclusion, detection of CTCs is an independent and strong prognostic factor in CRC, which might improve the identification of high-risk patients in future clinical trials.

Abstract Context The risk of persistent and recurrent disease in patients with differentiated thyroid cancer (DTC) is a continuum that ranges from very low to very high, even within the three primary risk categories. It is important to identify independent clinicopathological parameters to accurately predict clinical outcomes. Objective To examine the association between pre-ablation stimulated thyroglobulin (ps-Tg) and persistent and recurrent disease in DTC patients and investigate whether incorporation of ps-Tg could provide a more individualized estimate of clinical outcomes. Design, Setting, and Participants Medical records of 2524 DTC patients who underwent total thyroidectomy and radioiodine ablation between 2006 and 2018 were retrospectively reviewed. Main Outcome Measure Ps-Tg was measured under thyroid hormone withdrawal before remnant ablation. Association of ps-Tg and clinical outcomes. Results In multivariate analysis, age, ATA risk stratification, M1, ps-Tg and cumulative administered activities were the independent predictive factors for persistent/ recurrent disease. Receiver operating characteristic analysis identified ps-Tg cutoff (≤ 10.1 ng/mL) to predict disease free status with a negative predictive value of 95%, and validated for all ATA categories. Integration of ps-Tg into ATA risk categories indicated that the presence of ps-Tg ≤ 10.1 ng/mL was associated with a significantly decreased chance of having persistent/recurrent disease in intermediate- and high-risk patients (9.9 to 4.1% in intermediate-risk patients, and 33.1 to 8.5% in high-risk patients). Conclusion Ps-Tg (≤ 10.1 ng/mL) was a key predictor of clinical outcomes in DTC patients. Its incorporation as a variable in the ATA risk stratification system could more accurately predict clinical outcomes.

Personalized treatment vs. standard of care is much debated, especially in clinical practice. Here we investigated whether overall survival differences in metastatic colorectal cancer patients are explained by tumor mutation profiles or by treatment differences in real clinical practice. Our retrospective study of metastatic colorectal cancer patients of confirmed European ancestry comprised 54 Americans and 54 gender-matched Germans. The Americans received standard of care, and on treatment failure, 35 patients received individualized treatments. The German patients received standard of care only. Tumor mutations, tumor mutation burden and microsatellite status were identified by using the FoundationOne assay or the IDT Pan-Cancer assay. High-risk patients were identified according to the mutational classification by Schell and colleagues. Results: Kaplan–Meier estimates show the high-risk patients to survive 16 months longer under individualized treatments than those under only standard of care, in the median (p < 0.001). Tumor mutation profiles stratify patients by risk groups but not by country. Conclusions: High-risk patients appear to survive significantly longer (p < 0.001) if they receive individualized treatments after the exhaustion of standard of care treatments. Secondly, the tumor mutation landscape in Americans and Germans is congruent and thus warrants the transatlantic exchange of successful treatment protocols and the harmonization of guidelines.

Introduction. Current modalities to predict tumor recurrence and survival in esophageal cancer are insufficient. Even in lymph node-negative patients, a locoregional and distant relapse is common. Hence, more precise staging methods are needed. So far, only the CellSearch system was used to detect circulating tumor cells (CTC) with clinical relevance in esophageal cancer patients. Studies analyzing different CTC detection assays using advanced enrichment techniques to potentially increase the sensitivity are missing. Methods. In this single-center, prospective study, peripheral blood samples from 90 esophageal cancer patients were obtained preoperatively and analyzed for the presence of CTCs by Magnetic Cell Separation (MACS) enrichment (combined anti-cytokeratin and anti-epithelial cell adhesion molecules (EpCAM)), with subsequent immunocytochemical staining. Data were correlated with clinicopathological parameters and patient outcomes. Results. CTCs were detected in 25.6% (23/90) of the patients by combined cytokeratin/EpCAM enrichment (0–150 CTCs/7.5 mL). No significant correlation between histopathological parameters and CTC detection was found. Survival analysis revealed that the presence of more than two CTCs correlated with significantly shorter overall survival (OS) and progression-free survival (PFS). Conclusion. With the use of cytokeratin as an additional enrichment target, the CTC detection rate in esophageal cancer patients can be elevated and displays the heterogeneity of cytokeratin (CK) and EpCAM expression. The presence of >2CTCs correlated with a shorter relapse-free and overall survival in a univariate analysis, but not in a multivariate setting. Moreover, our results suggest that the CK7/8+/EpCAM+ or CK7/8+/EpCAM− CTC subtype does not lead to an advanced tumor staging tool in non-metastatic esophageal cancer (EC) patients.

Abstract Abstract 170 The effect of Rituximab in conjunction with a chemo induction and consolidation therapy was studied in CD20+, Ph/BCR-ABL negative B-precursor ALL (Pre-B/Common) in the GMALL Study 07/2003. The rationale were encouraging results with combined intensive chemotherapy and Rituximab in CD20+ adult Burkitt lymphoma / leukemia. Furthermore that in previous GMALL studies, improvement of B-precursor ALL by intensification of chemotherapy was limited and the observation that patients with CD20+ cells (antigen expression >20%) had an inferior outcome in adult ALL (Thomas et al. Blood 2009. 113;6330). Aim: In standard risk (SR) patients the aim was to increase the rate of molecular remission (Mol. CR) thereby decreasing the relapse rate and in high risk (HR) patients to reduce the pre-transplant tumour-load and thereby reducing the relapse rate after SCT which was 30–40% in previous GMALL studies. Materials and Methods: Adult ALL patients (15 – 55 years) with standard risk B-precursor ALL being CD20 pos. received Rituximab 375 mg/m2 at day -1 before each induction course (phase I and II), the re-induction course and before each of the six consolidations for a total of 8 doses. High Risk patients, defined as WBC > 30.000 and/or late CR > 4 weeks, which are candidates for a stem cell transplantation in CR 1 after wk 16, received Rituximab three times (d -1 ind. I/II and Cons. I) before SCT. Patients receiving Rituximab were compared with earlier CD20+ patients in the GMALL study 07/2003 with identical chemo- and supportive therapy but no Rituximab. MRD method and chemo backbone was described earlier [Brüggemann, Blood 2006: 107;1116]. Results: A total of 263 CD20 pos. patients were analyzed in the GMALL study 07/2003; 196 were SR and 67 HR patients. 181 received Rituximab (R+ arm) and were compared to a cohort of 82 patients earlier recruited without Rituximab (R- arm). In the SR there was no difference in the results of induction therapy with a CR rate of 94 % and 91 % in the R+ vs. R- patients. There was also no difference in ED rate 5% vs. 3% or failure/PR 1% vs. 5%. However, MRD course differed substantially. Decrease in MRD load in the R+ vs. R- arm was faster with a Mol CR (MRD <10-4) rate of 57% vs. 27% at day 24 and of 90% vs. 59% at wk 16. Probability for continuous complete remission (CCR) at 5 years was 80% vs. 47% for R+ vs. R- pts. and for overall survival 71% vs. 57%. In the cohort of 67 HR patients the CR rate for R+ vs. R- was 81% vs. 88% due to a higher rate of failure/PR 12% vs. 8%. The ED rates in the R+ vs. R- arm were 7% vs. 4%. There was a higher Mol CR rate at wk 16 in the R+ arm vs. R- with 64% vs. 40%. Overall survival for HR patients at 5 yrs was 55% vs. 36% in the R+ vs. R- group. When only the HR cohort with SCT in CR1 is considered (in 69 % +R and 90% -R SCT in CR1 were performed) the CCR probability was superior for the R+ vs. R- with 67% vs. 37%, due to a lower relapse rate. Conclusion: Intensive chemo- plus immunotherapy with Rituximab is feasible in adult patients with B-precursor ALL in the context of the GMALL protocol 07/2003. In standard risk patients, the complete remission rate was comparable. There was however a faster and higher Mol. CR rate in the Rituximab cohort, with an improvement in remission duration and overall survival. In high risk patients the Mol. CR rate was also higher in the R+ arm and the relapse rate after SCT lower, but probably more Rituximab doses are needed in this patient cohort to reduce the tumour load before SCT further.
