Benefit of second-line therapy for advanced esophageal squamous cell carcinoma: a tri-center propensity score analysis

BACKGROUND: The level of evidence for palliative second-line therapy in advanced esophageal squamous cell carcinoma (aESCC) is limited. This is the first study that reports efficacy data comparing second-line therapy + active symptom control (ASC) versus ASC alone in aESCC. METHODS: We conducted a tri-center retrospective cohort study (n = 166) including patients with aESCC who had experienced disease progression on palliative first-line therapy. A propensity score model using inverse probability of treatment weighting (IPTW) was implemented for comparative efficacy analysis of overall survival (OS) in patients with second-line + ASC (n = 92, 55%) versus ASC alone (n = 74, 45%). RESULTS: The most frequent second-line regimens used were docetaxel (36%) and paclitaxel (18%). In unadjusted primary endpoint analysis, second-line + ASC was associated with significantly longer OS compared with ASC alone [hazard ratio (HR) = 0.49, 95% confidence interval (CI): 0.35–0.69, p < 0.0001]. However, patients in the second-line + ASC group were characterized by more favorable baseline features including a better Eastern Cooperative Oncology Group (ECOG) performance status, a longer first-line treatment duration and lower C-reactive protein levels. After rigorous adjusting for baseline confounders by re-weighting the data with the IPTW the favorable association between second-line and longer OS weakened but prevailed. The median OS was 6.1 months in the second-line + ASC group and 3.2 months in the ASC group, respectively (IPTW-adjusted HR = 0.40, 95% CI: 0.24–0.69, p = 0.001). Importantly, the benefit of second-line was consistent across several clinical subgroups, including patients with ECOG performance status ⩾1 and age ⩾65 years. The most common grade 3 or 4 adverse events associated with palliative second-line therapy were hematological toxicities. CONCLUSION: This real-world study supports the concept that systemic second-line therapy prolongs survival in patients with aESCC

Successful use of sorafenib after bortezomib failure in metastatic follicular thyroid cancer - a case report

&lt;b&gt;&lt;i&gt;Background: &lt;/i&gt;&lt;/b&gt;Thyroid cancer (TC) is the most commonly diagnosed endocrine malignancy in developed countries. Differentiated thyroid carcinoma (DTC), which includes papillary thyroid carcinoma and follicular thyroid carcinoma (FTC), composes more than 90% of all TC cases. When DTC recurs or metastasizes to distant sites despite the use of local and radiotherapeutic treatment modalities, the currently effective treatment options are limited. &lt;b&gt;&lt;i&gt;Case Report: &lt;/i&gt;&lt;/b&gt;A then 40-year-old female Caucasian patient was diagnosed with FTC and underwent surgery and postoperative radioactive iodine therapy. The patient developed metastatic disease, and palliative first-line treatment with the proteasome inhibitor bortezomib was initiated. After 3 months, the patient suffered progressive pulmonary metastatic disease. Treatment with the multikinase inhibitor sorafenib was started, and after 3 months of therapy, tumor restaging demonstrated partial remission. The treatment is ongoing, and the current progression-free survival is 16 months. With the exception of mild diarrhea and hand-foot syndrome, the therapy was well tolerated, and no grade 3/4 adverse toxicities occurred. &lt;b&gt;&lt;i&gt;Conclusion: &lt;/i&gt;&lt;/b&gt;In our single case of metastatic FTC, sorafenib showed clinically meaningful antitumor activity accompanied by good tolerability. This case report supports the use of this drug as a potential treatment option for advanced/metastatic FTC.</jats:p

The lymphocyte to monocyte ratio in peripheral blood represents a novel prognostic marker in patients with pancreatic cancer

AbstractIntra-tumoral macrophages have been involved as important players in the pathogenesis and progression of cancer. Recently, inflammatory parameters of the systemic inflammatory response have also been proposed as usefully prognostic biomarkers. One of these, the lymphocyte to monocyte ratio (LMR) in peripheral blood has been shown as a prognostic factor in hematologic and some solid tumors. In this study we analyzed for the first time the prognostic value of LMR in a large middle European cohort of pancreatic cancer (PC) patients.Data from 474 consecutive patients with ductal adenocarcinoma of the pancreas were evaluated retrospectively. Cancer-specific survival (CSS) was analyzed using the Kaplan-Meier method. To further evaluate the prognostic significance of the LMR, univariate and multivariate Cox regression models were calculated.Increased LMR at diagnosis was significantly associated with well-established prognostic factors, including high tumor stage and tumor grade (p&lt;0.05). In univariate analysis, we observed that an increased LMR was a significant factor for better CSS in PC patients (HR 0.70; 95% CI 0.57–0.85; p&lt;0.001). In multivariate analysis including age, Karnofsky Index, tumor grade, tumor stage, administration of chemotherapy, LMR and surgical resection, we confirmed increased LMR as an independent prognostic factor for CSS (HR 0.81; 95% CI 0.66–0.99; p=0.04).In conclusion, we identified LMR as an independent prognostic factor in PC patients. Our results indicate that the LMR might represent a novel and useful marker for patient stratification in PC management.</jats:p

Evaluation of uric acid as a prognostic blood-based marker in a large cohort of pancreatic cancer patients.

BACKGROUND: Recently, chemical blood parameters gain more attraction as potential prognostic parameters in pancreatic cancer (PC). In the present study we investigated the prognostic relevance of the uric acid (UA) level in blood plasma at the time of diagnosis for overall survival (OS) in a large cohort of patients with PC. PATIENTS AND METHODS: Data from 466 consecutive patients with ductal adenocarcinoma of the pancreas were evaluated retrospectively. Overall survival (OS) was analysed using the Kaplan-Meier method. To further evaluate the prognostic significance of the UA level, univariate and multivariate Cox regression models were calculated. RESULTS: None of the clinicopathological parameters (tumour grade, clinical stage, age, CA19-9 level, Karnofski Index (KI) or surgical resection) except gender was associated with UA level. In univariate analysis we observed the elevated UA level (<5.1 versus ≥5.1 mg/dl, p = 0.017) as poor prognostic factor for OS. In the multivariate analysis that included age, gender, tumour grade, tumour stage, surgical resection, CA19-9 level, the KI and UA level we confirmed the UA level as independent prognostic factor for OS (HR = 1.373%; CI = 1.077-1.751; p = 0.011). CONCLUSION: In conclusion, we identified the UA level at time of diagnosis as an independent prognostic factor in PC patients. Our results indicate that the UA level might represent a novel and useful marker for patient stratification in PC management
