作者： ghada ezzat eladawei Clinical Oncology and Nuclear Medicine Department Mansoura University Mansoura Egypt

Background and Objective: There is marked controversy regarding optimal management patients with stage IB grade III endometrial carcinoma. The present study analyzes the current practices regarding adjuvant radiation therapy for those patients in our institute and also assessed prognostic factor affecting overall survival outcome. Patients and Methods: A total 66 patients with postoperative FIGO stage 1B, grade III endometrial carcinoma were treated and evaluated between the years 2009 and 2014. Risk factors assessed age (4 cm), site of primary tumor (involvement of lower uterine segment versus no involvement), Lymphadenectomy (performed versus not performed), Lymph-vascular space invasion (positive or negative), type of surgery performed (less than total abdominal hysterectomy and bilateral salpingo-ophorectomy (TH/BSO) versus greater than or equal TH/BSO), radiation sequence with surgery (no radiation versus adjuvant radiation), and type of radiation (pelvic external beam radiotherapy versus vaginal brachytherapy versus both). Results: Adjuvant radiation therapy after surgery was associated with significantly better time to relapse (p = 0.001) in comparison to those patients who underwent surgery alone. There was statistically significant improvement of survival of patients who received adjuvant radiation therapy in comparison with those who underwent surgery alone. There was no statistically significant difference in relapse between external pelvic radiotherapy, brachytherapy and both (p = 0.161). There was no statistically significant difference in overall survival between different types of adjuvant radiation therapy (p = 0.318). Adjuvant radiation therapy (HR 0.173, 95% CI 0.049 - 0.609, p = 0.006) and tumor size (HR 4.065, 95% CI 1.120 - 14.761, p = 0.033) were the only statistically significant predictors for relapse in multivariate analysis. Adjuvant radiation therapy (HR 0.159, 95% CI 0.045 - 0.563, p = 0.004), ag

Journal of Cancer Therapy 2019年第8期10卷 619-631页

Introduction and objectives: Salvage treatment of recurrent Glioblastoma (GBM) is one of the most challenging tasks in neuro-oncology. There is no standard treatment for recurrent GBM as options include resection, chemotherapy, and re-irradiation either separate or in combination. Role of concomitant temozolamide with re-irradiation in recurrent disease is still debatable. Therefore, this study evaluates efficacy of concurrent and adjuvant temozolamide with re-irradiation in management of recurrent GBM. Patients and methods: Twenty two patients with recurrent glioblastoma were eligible. Patients were treated with 3 D conformal radiotherapy. The dose ranged from 30 to 40 Gy in 1.6 to 1.8 Gy per fraction for 5 days per week. Temozolamide was administrated at 50 mg/m2 daily dose during radiation therapy. Adjuvant Temozolomide (200 mg/m2) was given orally for five days every four weeks for 4 - 6 cycles for patients who did not receive temozolamide before, and 150 mg/m2 for pretreated patients. Results: 22 patients received re-irradiation with median dose 38 Gy (range 33 - 40 Gy), concurrent with temozolamide. The time interval between primary and re-irradiation ranged from 6 to 23 months with median 12 months. The re-irradiated volume, median was 101.95 cm3 (range 30 - 375 cm3). The median cumulative maximum dose to optic system and brain stem were 53.5 Gy (range 42 - 63 Gy), and 60 Gy (range 54 - 73 Gy), respectively. Response rate was 72.7%, one patient showed complete response (4.5%), partial response and stable disease registered in 22.7% and 45.5%, respectively. The median overall survival (OS) was 10 months (range 4 - 13 months), and median progression-free (PFS) survival was 7.5 months (range 2 - 11 months). The 6 and 12 months OS rate was 100% and 56.6% respectively, and the 6 months PFS rate was 93.3%. No major acute toxicity was observed. About 70% of patients experienced grade 2 toxicity in the form of headache, nausea & vomiting, skin erythema and alopecia.

The Lower Peripheral Blood Lymphocyte to Monocyte Ratio Following Completion of First Line Chemotherapy Is a Risk Factor for Predicting Relapse in Patients with Diffuse Large B-Cell Lymphoma

Background and objective: During routine follow up, there is no specific predictor to ascertain relapse after standard first line chemotherapy in diffuse large cell lymphoma. Therefore, this study was designed to assess the prognostic significance of the ratio between absolute lymphocyte and monocyte counts (LMR) in the peripheral blood to verify relapse in diffuse large B cell lymphoma. Patients and methods: A total of 139 patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) were evaluated and treated with CHOP or R-CHOP between the years 2009 and 2016. Three months following completion of first line therapy, Lymphocyte/monocyte ratio (LMR) was calculated from the routine automated complete blood cell count (CBC) attained a plateau after the bone marrow recovery after first line chemotherapy. The absolute lymphocyte count/absolute monocyte count ratio (LMR) was calculated by dividing the ALC by the AMC. Results: ROC curve analysis of 139 patients established 2.8 as cutoff point of LMR for relapse with AUC of 0.97 (95% CI 0.93 - 0.99, P ≤ 0.001). Cox regression analysis was performed to identify factors predicting relapse. In univariate regression analysis, ALC (95% CI 0.003 - 0.03, p ≤ 0.001), AMC (95% CI 15.4 - 128.8, p ≤ 0.001), LMR (95% CI 0.001 - 0.01, p ≤ 0.001), and LDH (95% CI 0.1 - 0.5, p ≤ 0.001) following completion of therapy are significant factors for relapse. Other significant factors for relapse are Ann Arbor stage (95% CI 1.1 - 6.9, P = 0.03), extranodal sites (95% CI 1.2 - 6.1, P = 0.01), age (95% CI 1.3 - 6.5, P = 0.01) and treatment of CHOP protocol (95% CI 0.05 - 0.6, P = 0.007). In a multivariate analysis LMR following completion of therapy was predictive for relapse (95% CI 0.001 - 0.2, P = 0.005). ALC was also significant in multivariate analysis (95% CI 0.01 - 0.8, P = 0.03). LDH following completion of therapy (95% CI 0.2 - 14.9, P = 0.5), AMC following completion of therapy (95% CI 0.3 - 43.1, P = 0.3), age (95% CI 0.9 - 205

Local Consolidation Therapy versus Observation for Oligometastatic Non Small Cell Lung Cancer Patients: Phase II Randomized Trial

引用

Journal of Cancer Therapy 2018年第11期9卷 925-940页

作者： ghada ezzat eladawei Rasha Mohamed Abdellatif Sheref Mohamed El-Taher Clinical Oncology and Nuclear Medicine Department Mansoura University Mansoura Egypt Public Health & Community Medicine Department Benha University Benha Egypt

Background and Objective: Based on retrospective trials, most progression sites after first line systemic therapy for metastatic non small cell lung cancer (NSCLC) were the primary disease sites rather than new sites. Therefore we conducted phase II randomized study to determine whether oligometastatic NSCLC without disease progression after first line chemotherapy, have prolonged progression free survival when treated with local consolidation therapy of residual disease followed by surveillance compared with no local consolidation therapy (observation). Patients and Methods: Forty eight eligible patients were randomized to either immediate or no local consolidation radiotherapy. 26 patients of immediate local consolidation radiotherapy received 3 D-conformal radiation therapy to primary tumor site and metastatic sites of disease. 22 patients were followed up by observation. Results: Patients in local consolidation arm had significantly better progression free survival (PFS) compared with patients in observation group. Median PFS was 9.5 months (95% CI 7.8 - 11.08) in local consolidation arm and 4.5 months (95%CI 3.9 - 5.7) in observation arm. Patients in local consolidation arm had longer median time to appearance of new metastatic sites (10 months CI 9.3 - 12.6) than those patients in observation arm (4.5 months CI 4.2 - 6.9). Median overall survival (OS) of patients in local consolidation arm was 12 months (95% CI 12.1 - 18.01) and in observation arm 10 months (95% CI 8.7 - 13.8). One year OS rate was 42.3% in local consolidation arm and 31.8% in observation arm;2 year OS rate was 23.1% in local consolidation arm and only 4.5% in observation arm. Conclusion: Local consolidation radiotherapy is simple, safe, efficient, and not expensive treatment for oligometastatic non small cell lung cancer after upfront chemotherapy. Local consolidation radiotherapy achieved significantly prolonged progression free survival and delayed appearance of new metastatic sites. Phase
