8%), followed by linalool (2.8%) and (-)-alpha-terpineol (2.7%). The 2-hydroxy-4-methoxy-benzaldehyde was further isolated and identified by bioassay-directed fractionation. The compound showed strong contact toxicity against D. melanogaster and the maize weevil (Sitophilus CBL0137 zeamais) with LD50 values of 1.47 and 6.99 mu g/adult, respectively.”
“Purpose
The degree of benefit from palliative chemotherapy differs widely among patients with metastatic esophageal
squamous cell carcinoma (MESCC). The purpose of this study was to develop and validate a prognostic nomogram to predict survival and aid physicians and patients in the decision-making process regarding treatment options.
Materials and Methods
Clinicopathologic variables and treatment outcomes of 239 patients who were diagnosed with MESCC and received either fluorouracil/cisplatin (FP) or capecitabine/cisplatin (XP) as first-line chemotherapy were reviewed. A nomogram was developed as a prognostic scoring system incorporating
significant clinical and check details laboratory variables based on a multivariate Cox proportional hazards regression model. An independent series of 61 MESCC patients treated with FP served as an independent data set for nomogram validation.
Results
No difference in response rate was observed between the FP group (44.8%) and the XP group (54.2%). Similarly, no significant differences in median progression-free survival and median overall survival were observed between regimen groups. Multivariate analysis showed that poor performance status (Eastern Cooperative Oncology Group [ECOG] status >= 2), weight loss (10% of the weight loss for 3 months), low albumin level (<= 3.5 g/dL), and absence of previous esophagectomy
at the time of chemotherapy were significantly associated with low OS in both groups (p < 0.05). Based on these findings, patients were classified into favorable (score, 0 to 90), intermediate (91-134), and poor (>135) prognostic groups. The median AR-13324 survival for those with a favorable ECOG was 13.8 months (95% confidence interval [CI], 10.8 to 18.6 months), for intermediate 11.2 months (95% Cl, 8.7 to 11.9 months), and for poor, 7.0 months (95% Cl, 3.6 to 10.0 months). External validation of the nomogram in a different patient cohort yielded significantly similar findings.
Conclusion
The nomogram described here predicts survival in MESCC patients and could serve as a guide for the use of FP/XP chemotherapy in MESCC patients.”
“Cisplatin is an anticancer drug extensively used against a variety of cancers. Cisplatin chemotherapy is found to manifest dose-dependent nephrotoxicity. Depletion of the renal antioxidant defence system has been suggested to be the main cause of cisplatin-induced nephrotoxicity.
