The efficacy and safety of Oxaliplatin-Vinorelbine as a second-line chemotherapy combination in patients with platinum-resistant pretreated epithelial ovarian cancer: A retrospective study

Purpose: The main purpose of this study was to analyze the effects and tolerability of Oxaliplatin-Vinorelbine combination on Platinum-resistant epithelial ovarian carcinoma (EOC) patients.Methods: A single centered retrospective study comprising of 34 patients was conducted, and all 34 patients were treated with Vinorelbine 30 mg/m2 on day 1 and 8 along with Oxaliplatin 100 mg/m2 on day 1 of 3 weeks treatment cycle following progressive platinum-resistant EOC. Results: The combination showed an overall response rate (ORR) of 18% (95% CI, 4.4 - 31.6) where 2 (6%) patients had complete response and 4 (12%) patients had partial response. Stable disease was observed in 9 (26%) patients and progressive disease in 19 (56%) patients. Median diseases free survival, median relapse free survival and median time to progression was 17.05 months, 4.4 months, and 1.25 months, respectively. Hematological toxicities were mild; only 1 (2.9%) patient had G3 anemia and major non-hematological toxicities include nausea-vomiting, diarrhea, constipation, hepatotoxicity, fatigueness and alopecia, which are mainly limited to G1-G2 and reversible. Conclusion: The effect of this combination is moderate as a second line treatment of platinum resistant EOC; however, in comparison with other regimens of Vinorelbine and Oxaliplatin, the activity is substandard but the toxicity profile is well tolerable. Further multicenter evaluation is needed for the better understanding of the therapeutic efficacy of the combination

The existence of Th22, pure Th17 and Th1 cells in CIN and Cervical Cancer along with their frequency variation in different stages of cervical cancer

BACKGROUND: Recently, it is found that T-helper (Th) 22 cells are involved in different types of autoimmune and tumor diseases. But, till now, no study has been carried out to understand the involvement of these cells in cervical cancer (CC). METHODS: Flow cytometry was used to determine the expression of interferon gamma (IFN-gamma), Interleukin-22 (IL-22), IL-17 in the peripheral blood of healthy controls (HC), CIN and cervical cancer patients. From peripheral blood mononuclear cells (PBMCs), mRNA expression levels of Aryl hydrocarbon receptor (AHR), RAR-related orphan receptor C (RORC), TNF-alpha and IL-6 were respectively determined. Using the method of ELISA, plasma concentrations of IL-22, IL-17 and TNF-alpha were examined. RESULTS: Th22 and Th17 cells were elevated in CC and CIN patients. Th1 cells and the plasma concentrations of IL-22 in CC patients were significantly increased compared with HC. In CC patients, an increased prevalence of Th22 cells was associated with lymph node metastases. There was a positive correlation between Th22 and Th17 cells, but an approximately negative correlation between Th22 and Th1 cells in CC patients. The mRNA expression of RORC, TNF-alpha and IL-6 was significantly high in CC patients. CONCLUSIONS: Our results indicate that there is a higher circulatory frequency of Th22, Th17 and Th1 cells in CC which may conjointly participate in the pathogenesis and growth of CC.This item is part of the UA Faculty Publications collection.
