A Clinic-Epidemilogical Study of Cases of Locally Advanced Non Small Cell Lung Cancer (NSCLC) That Received Radiotherapy at NCI Cairo in the Period from 2001-2010

Purpose: This work was to study the clinic-epidemiological characteristics of patients with locally advanced NCSLC and to analyze their prognostic factors and also the results of different treatment modalities for local control and their effect on overall survival (OAS). Materials and Methods: This is a retrospective study including 121 patients with primary locally advanced NSCLC diagnosed between 2001 and 2010 at the radiotherapy department , National Cancer Institute, Cairo University, Egypt. Results: The study showed significant correlation between the tumor size 60, moderately differentiated tumors G2 and treatment outcomes;better locoregional control and better survival rates. On the opposite side poorly differentiated tumors G3, tumor size > 7 cm had the worst locoregional control and survival rates. The study also showed significant statistical correlation between treatment modality, locoregional control and survival rates. Patients who were treated by either concommitent chemo-radiotherapy or sequential chemo-radiotherapy had better local control compared to other patients who were treated by radical radiotherapy, and they also had the best survival rates among all the other treatment groups. The average 6 months OAS rates for all studied patients were 60.3% while 12 months survival rates were 38.8%. The median OAS was 7 months. Conclusions: From the present study, we concluded that concomitant chemo-radiotherapy is the treatment of choice for locally advanced non small cell lung cancer;also we concluded that better performance status and higher hemoglobin levels have better treatment outcome in these cases.

A clinicoepidemiological study of esophageal cancer patients at the National Cancer Institute,Cairo University,Egypt

Objective The purposes of this study were to （1） assess the clinicoepidemiological characteristics of esopha-geal cancer patients, （2） analyze the prognostic factors determining treatment failure and survival, and （3） evaluate the results of various treatment modalities for locoregional and disseminated disease and their ef ect on disease-free survival and overal survival （OS）.Methods Clinicoepidemiological retrospective data from 81 esophageal cancer patients treated at the Na-tional Cancer Institute of Cairo between 2007 and 2011 were evaluated. Results The study showed that patients with esophageal cancer commonly present with local y advanced disease （87.7% had T-stage 3 and 12.3% had T-stage 4）. There was a significant correlation between surgery and survival; patients who received radical surgery and postoperative radiation had a better median survival than patients who received radical radiotherapy （20 months vs. 16 months, respectively; P = 0.04）. There was also a significant statistical correlation between radical concomitant chemoradiotherapy （NCRT） and pal iative treatment. Patients who received radical NCRT had a better median survival than patients who received pal-liative radiotherapy （16 months vs. 10 months, respectively; P = 0.001）. The median fol ow-up period for al patients was 7 months. The median OS of the whole group was 12 months. The OS after 1 and 2 years was 57.8% and 15%, respectively.Conclusion High-dose NCRT is an acceptable alternative for patients unfit for surgery or with inoperable disease. High-dose radiation is more ef ective than low-dose radiation in terms of local control, time to relapse, and OS. Further study using a larger series of patients and introducing new treatment protocols is necessary for a final evaluation.
