Methods： A retrospective review of 80 International Federation of Gyne- cology and Obstetrics （FIGO） stage Ic grade 3 endometrial carcinoma patients treated between October 1994 and October 2004 at Renmin Hospital, Wuhan University, China was performed. All patients underwent surgery, of which 40 patients in arm I received combined MPA and EBRT while in arm II 40 patients received only adjuvant EBRT after surgery. The median dose of EBRT in arm I was 50 Gy （range 36-54 Gy） and in arm Ⅱ was 45.2 Gy （range 43.2-50.4 Gy）. Multivariate analysis was performed for the prognostic factors and Kaplan-Meier method was used for overall survival. Results： Of the 80 eligible patients, 40 in each group could be evaluated. The follow-up times ranged from 4-98 months with a median of 45 months. The overall survival rates at five years were 73% among patients treated with combined MPA and EBRT and 28.2% among patients treated with EBRT alone （P 〈 0.001）. The rate of distant metastasis was significantly higher among patients treated with EBRT alone group than combined MPA and EBRT （55% vs 25%, P = 0.006） while no difference in Ioco regional recurrence rates was observed in both treatment groups. Most of the side effects observed in the combined MPA and EBRT group. Age （P 〈 0.001） and the presence of progesterone receptors （P = 0.003） were independent significant prognostic factors for overall surviva} in multiple regression analysis. Conclusion： We has been concluded that the addition of progestagen to external beam pelvic radiotherapy significantly improved survival and reduced distant metastasis among women with stage Ic grade 3 endometrial cancer.展开更多

The incidence is less than 1 per 1 million per year. Usually it is located in the diaphysis of long bones. Prognosis of these tumours has improved dramatically since the introduction of multi-agent chemotherapy, from an erstwhile 10% survival rate to the current 70% for patients with non-metastatic Ewing sarcoma. Method: A retrospective review of patients with histologically confirmed Ewing sarcoma who were treated in the Department of Orthopaedics, B.S. Medical College during the time period from April 2000 to March 2012 was performed. Patients were divided into two groups: Group A included those treated by External Beam Radiotherapy (EBRT) + chemotherapy while Group B included the patients treated with surgery + chemotherapy. Results were analysed depending on the survival rates. Kaplan-Meier survival curves were compared using log-rank test and a multivariate Cox proportional hazards model was calculated. Result: The survival curves of both the groups were not found to be significantly different. Conclusion: Treatment of Ewing tumour has multiple options. No one treatment modality is superior. Survival rates of patients treated by radiation + chemotherapy are not significantly different from those treated with surgery + chemotherapy.展开更多

The general situation of radiation oncology and recommendation for improvement of radiotherapy services in the country were also highlighted. Further assessment was to investigate and determine the relationship between age, different types of cancer, and gender for cancer patients undergoing radiotherapy treatment. Materials and Methods: A data compilation, analysis, and evaluation process were conducted at two cancer treatment centers in Kenya followed by an assessment of radiotherapy cancer treatment facilities in the country. The number of the patients treated for cervical, breast prostate, esophagus, rectum, and lung cancer against their ages and gender were also compiled for assessment. Results: The number of cancer patients treated by radiotherapy continuously increased annually and he trends of the graphs in both centers were similar. Cervical cancer was the most common cancer treated by radiotherapy at the two centers, followed by breast and prostate cancer. Different types of cancer assessed were dependent on age and that cancer appeared at younger ages in female cervical and breast cancer patients as opposed to the male prostate cancer. Conclusion: The results indicate a continuous annual increase in cancer patients treated by radiotherapy in Kenya radiotherapy centers. The increase may be attributed to the rising population, limited access to cancer awareness, and the growing adoption of unhealthy lifestyles, among other factors. Female cervical and breast cancer patients contracted the disease at younger ages (46 - 50 years) compared to the male prostate cancer patients with a mean age of 61 - 65 years. Socio-economic factors, the organization of healthcare systems, and a limited workforce have been identified as some of the barriers to the provision of proper radiotherapy services in the country.展开更多
