Item Concurrent chemoradiotherapy for head and neck cancers in older patients: Outcomes and their determinants(Indian Cancer Society, 2019-07) Srinivasalu, Vijay K; Subramaniam, Narayana; Balasubramanian, Deepak; Kumar, Narender; Philip, Arun; Susan, Annu; Pushpaja, KU; Nair, Anoop R; Thankappan, Krishnakumar; Jose, Wesley; Subramania, Iyer; Pavithran, KeechilatINTRODUCTION: Meta-analyses have shown concurrent chemoradiotherapy (CCRT) provides no survival benefit over radiotherapy in patients of head and neck squamous cell carcinoma (HNSCC) aged over 70 years. This study was performed to determine the adverse-effect profile, compliance, functional and oncological outcomes in patients of HNSCC over 70 years of age treated with CCRT. MATERIALS AND Methods: Retrospective analysis of stage III/IV HNSCC in patients above 70 years of age who received CCRT at our institution (n = 57). Cox-proportional hazards regression model was used for statistical analysis. RESULTS: There were 57 patients of stage III/IV HNSCC who underwent curative CCRT. 61% completed chemotherapy with no deaths and acceptable toxicity. The predictors of recurrence were poorer performance status (P = 0.031) and treatment breaks (P = 0.04). Tube dependence was associated with 2.7 times higher risk of mortality (P = 0.005). CONCLUSION: CCRT should be considered standard of care in those over seventy with good performance status. Patients with tube dependence have a higher risk of persistent disease or treatment related mortality.Item Pretreatment neutrophil?to?lymphocyte ratio predicts lymph node metastasis in triple?negative breast cancer(Wolters Kluwer - Medknow, 2022-04) Philip, Arun; Jose, Mathews; Jose, Wesley M.; K, Vijaykumar D.; Pavithran, KeechilatBackground: The purpose of the study was to investigate the value of pretreatment neutrophil-to-lymphocyte ratio (NLR) as a prognostic marker in triple-negative breast cancer (TNBC) and to see its bearing on the clinical and pathological stage of the disease. Methods: This was a retrospective analysis of cases of TNBC treated at our center from 2006 to 2013. The pretreatment complete blood count was recorded from which the NLR was calculated as the percentage of neutrophils divided by the percentage of lymphocytes. The association between pretreatment NLR with the stage of the disease, clinical and pathological lymph node status, and disease-specific survival was analyzed. Results: A total of 208 patients were eligible for the analysis. The median follow-up period was 48 months. The NLR was found to have a strong correlation with the pathological nodal status and the clinical stage (75% cases node-positive in the high NLR group versus 36% in the low NLR group; P < 0.01). At the time of analysis, 74% of our study population was alive and well. There was no significant correlation between the NLR and the overall survival. Conclusions: Based on our study, we conclude that the pretreatment NLR is strongly associated with lymph node metastasis and clinical stage in TNBC patients. It is probably not useful as a prognostic marker, as it does not seem to have any significant bearing on the overall survival.Item Primary Cns Lymphoma : Neutrophil To Lymphocyte Ratio Predictive Of Survival(World Wide Journals, 2019-10) Philip, Arun; Jose, Wesley; K, Beena; Keechilat, PavithranThe aim of this study was to analyze the prognostic factors in cases of primary CNS lymphoma (PCNSL) treated at our centre. A retrospective review of case records of PCNSL cases treated at our institute between 2005 and 2016 was performed. The prognostic value of age, sex, Serum Albumin, Neutrophil Lymphocyte Ratio (NLR), were assessed with respect to overall survival. Atotal of 32 patients were included in the study. The median NLR of the study population was 3.6. It was observed that patients with a low NLR (NLR≤3.9) had a significantly better median overall survival compared to the high NLR group (NLR>3.9) [58 months vs 15 months; p=0.011]. We found that the NLR is a unique prognostic tool that predicts survival in PCNSL.Item Prognostic significance of residual nodal burden using lymph node ratio in locally advanced breast cancer after neoadjuvant chemotherapy(Indian Cancer Society, 2019-07) Agarwal, Reshu; Philip, Arun; Pavithran, Keechilat; Rajanbabu, Anupama; Goel, Gaurav; Vijaykumar, DKOBJECTIVE: To investigate the prognostic value of lymph node ratio (LNR) after neoadjuvant chemotherapy (NAC) according to breast cancer molecular subtypes. METHODS: From 2004 to 2014, patients with definitive surgery after NAC were identified. LNR was calculated for node positive patients who underwent axillary dissection and at least 10 nodes (LNT) were removed. Disease free and overall survivals were analysed using Kaplan-Meier test and compared using log rank test for ypN0-3, LNR categories (LNRC) ≤0.2 (low), 0.21-0.65 (intermediate), >0.65 (high), and single LNR cut-off value. RESULTS: Of 224 analysed patients: ypN0 72 (32.1%), ypN+ 152 (67.9%). Of 118 LNT ≥10 ypN+ patients LNRC: Low risk 48 (40.7%), intermediate risk 36 (30.5%), high risk 34 (28.8%). Factors significantly different in LNR categories were ypN (P < 0.001); extranodal extension (P < 0.001); present status of patients (P < 0.001); and disease status (P = 0.029). LNRC was inversely associated with 5-year DFS: Low 52.3%, intermediate 40%, and high 12.2% (log rank P < 0.001); and OS: Low 64.4%, intermediate 58.3%, and high 13.6% (log rank P < 0.001). Significant association of LNRC and DFS and OS were demonstrated in TNBC (P < 0.001) and HER2 subtypes (P = 0.045 and 0.005 respectively). A single value of LNR = 0.25 in node positive was found significant for DFS and OS in TNBC (P < 0.001) and Her2+ (P = 0.013 and P = 0.001 respectively) but not for HR+ (DFS: P = 0.132; OS: P = 0.144). CONCLUSION: Residual nodal disease after NAC analysed by LNRC or LNR = 0.25 cut-off value, is prognostic and can discriminate between favourable and unfavourable outcomes for TNBC and Her2+ breast cancers.
