Neutrophil-to-lymphocyte ratio and chemotherapy response score as prognostic markers in ovarian cancer patients treated with neoadjuvant chemotherapy.

BACKGROUND: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is the recommended approach in patients with advanced epithelial ovarian cancer (EOC). However, most patients eventually relapse despite the initial high response rate to chemotherapy. Neutrophil-to-lymphocyte ratio is a well-known biomarker that reflects severe inflammation, critical illness, and mortality in various diseases. Chemotherapy response score (CRS) and neutrophil-to-lymphocyte ratio (NLR) have been identified as potential biomarkers of platinum resistance and disease prognosis. We retrospectively evaluated 132 patients with stage IIIc or IV ovarian/fallopian tube/primary peritoneal cancer who had received NACT followed by IDS from 01/01/2003 to 31/12/2018. CRS was assessed on omental specimens collected from IDS according to ICCR guidelines. RESULTS: Median age was 64.57 years (SD: 9.72; range 39.2-87.1). Most ovarian tumors were serous epithelial (90.9%; 120/132). An elevated NLR (defined as > 3) was observed in 72% (95/132) of patients in contrast with 28% (37/132) of patients characterized by low NLR status. Median PFS (mPFS) and median overall survival (mOS) were 13.05 months (95% CI: 11.42-14.67)) and 34.69 months (95% CI: 23.26-46.12) respectively. In univariate analysis, CRS3 score was significantly associated with prolonged mPFS (CRS1/2: 12.79 months vs CRS3: 17.7 months; P = 0.008). CRS score was not associated with mOS (P = 0.876). High NLR was not significantly associated with mPFS (P = 0.128), however it was significantly associated with poor mOS (P = 0.012). In multivariate analysis, only performance of surgery maintained its statistical significance with both PFS (P = 0.001) and OS (P = 0.008). CONCLUSION: NLR could serve as a useful predictor of OS but not PFS in ovarian cancer patients receiving NACT. In accordance with our previous study, CRS score at omentum was found to be associated with PFS but not OS in ovarian cancer patients treated with NACT and IDS.

Biomarkers that would predict response to neoadjuvant chemotherapy in advanced ovarian cancer patients are eagerly needed:• Neutrophil to Lymphocyte Ratio (NLR) is an indicator of systemic inflammatory response to the malignancy.• NLR was evaluated in 132 patients undergoing Neoadjuvant Chemotherapy for advanced ovarian cancer.• Elevated NLR was associated with worse prognosis.• No association between NLR and response to chemotherapy was noted.

Axitinib as a third or further line of treatment in renal cancer: a single institution experience.

BACKGROUND: Kidney cancer is a lethal neoplasm that affects several thousands of people every year. Renal cell carcinoma (RCC) is the most common histologic type. Recent developments in the therapeutic approach include antiangiogenic targeted approaches and Immunotherapy. Thus, the therapeutic algorithm of RCC patients and the survival outcomes have changed dramatically. METHODS: Herein we present a retrospective study of the patients treated in our Department with an antiangiogenic agent -Axitinib, a tyrosine kinase inhibitor- as a third or further line treatment. Statistical analysis was performed with SPSS, including the available clinicopathological data of the patients included. RESULTS: Axitinib was found to be active in patients who received this treatment beyond second line. The toxicity profile of this regimen did not reveal any unknown adverse events. CONCLUSIONS: Our real world data reflect that axitinib is a safe and effective option, even beyond the second line.

Maintenance chemotherapy or not in ovarian cancer stages IIIA, B, C, and IV after disease recurrence.

PURPOSE: Ovarian cancer may have a high percentage of residual disease after chemotherapy. It is questionable whether second or more lines of chemotherapy are needed in patients with slow-growing residual disease. In the present trial we compared the median survival of patients with residual or recurrent disease who received 1-2 lines of chemotherapy with those who received 3-9 lines. METHODS: Two hundred and five patients with advanced stage IIIA, B, C and IV ovarian cancer were divided into two groups based on the number of chemotherapy lines they received. All patients had prior first-line chemotherapy; the criteria for recruitment in the study were: a) residual or recurrent disease and b) failure to respond to first-line therapy. Group A included patients who received 1 or 2 lines of chemotherapy and group B, 3-9 lines. RESULTS: The median survival of group A was 76 months and of group B 53 months (p<0.001). Complete response (CR) was observed in 80 out of the 193 7lpar;41.45%) evaluable patients, partial response (PR) in 37 (19.17%), stable disease (SD) in 54 (27.987percnt;) and progressive disease (PD) in 22 (11.40%) patients. CONCLUSION: In ovarian cancer patients with advanced disease, multiple chemotherapy lines (3=9) offer no advantage over 1 or 2 lines, with respect to overall survival.
