  • Title: [Radiation therapy and treatment results in carcinoma of the esophagus (author's transl)].
    Author: Wieland C, Hymmen U.
    Journal: Strahlentherapie; 1977 Nov; 153(11):719-25. PubMed ID: 337587.
    Abstract:
    Results from radiotherapeutic treatment of 200 patients with malignant tumors of the esophagus are reported. The principal part is represented by squamous cell carcinomas with 88%, followed by adenocarcinomas with 4.5%, by more or less differentiated solid carcinomas with 4%, and small cell carcinomas with 1.5%. Sarcoma was found in three cases, one of them a myosarcoma, another a reticulosarcoma. An ectopic carcinoma of the gastric glands was present in one case. The staging was performed according to the TNM system. A focal dose of 6000 to 6500 rd within 6 or 8 weeks was tried for, using 60Co-gamma-rays. The one-year and five-year survival rates in stage T2N0M0 amounted to 80% and to 17%; no survival was obtained in stage T3N0M0. Out of the total of stage T2-3N0M0 cases 24% obtained one-year survival, and 2% five-year survival. In stages T3N2-3M0 and T3Nx-3M1 after one year 9% and 7% of the patients were alive. The mean survival time of stage T2N0M0 cases was 30.5 months; of T3N0M0, 7.3 months; of T3N1-3M0, 5.2 months; of T3Nx-3M1, 3.8 months. The one-year and five-year survival rates, being related to the irradiation dose administered, amounted to 28% and to 2% after a minimum dose of 5000 rd to the focus. With less than 5000 rd, none of the patients survived two years. The bad results of treatment demand new therapeutic pathways. Short-term pre-irradiation followed by surgical treatment is discussed as well as a combined radiation therapy with cobalt-60 and neutrons or a combined radio-chemotherapy using cytostatics.
