Radiation Therapy Oncology Group, Philadelphia, PA This paper provides an introduction into the clinical activities of the RTOG (Radiation Therapy Oncology Group), its goals, its organization, its format for protocol development, and presents major areas of achievement. It provides an organizational chart of the group, a disease site modality cross-reference for protocols, and appendices which provide the key published results of the Group’s clinical activities. This paper presents an important overview of the RTOG clinical research activities, which are designed to improve the role of radiation therapy. Radiation Therapy Oncology Group, Clinical research. INTRODUCIION

rative and palliative results of cancer management; (c) to conduct clinical trials to advance the knowledge of radiation oncology; (d) to reduce the morbidity of radiation therapy while maintaining its efficacy; (e) to enhance cooperation among oncology specialists in providing multimodality treatment and to evaluate these in clinical trials; (f) to translate ideas from preclinical disciplines, such as, radiation and tumor biology, radiation physics, and pharmacology into clinical trials; (g) to collect long-term clinical information on patients treated in a consistent manner in order to identify potential new prognostic factors which may influence the interpretation of treatment results and aid in the design of future trials.

The Radiation Therapy Oncology Group (RTOG) is a North American clinical cooperative group with the goal of defining the optimum role of radiation therapy alone or in combination with other treatment modalities for cancer. Organized in 1968, it has grown since, in terms of the number of participating institutions, active studies, patients accessioned into clinical trials per year, and publications resulting from these clinical trials (l-4). The RTOG involves the cooperation and input of many individuals to achieve its goals. This brief paper will review the organization of the group and provide an important reference source for: the publications of the group and the current or recently closed protocols by scientific areas of interest within each disease site. The funds for participating institutions, headquarters, and other activities have come predominantly from the National Cancer Institute (grant No. CA2 166 l), through grants to the American College of Radiology, which have undergone periodic peer reviews. Some corporate sources of funding have also been obtained including Varian Corp. The RTOG is the main radiation therapy research arm of the ACR.

ORGANIZATION The organization of the RTOG consists of full-time employees, consultants, funded members and affiliates, and voluntary member institutions. The member institutions of the RTOG have varied somewhat over the past 22 years with some institutions having been continuous members. There have been a total of 4 12 institutions as members with 138 currently active. Full member institutions have a principal investigator, who a committee to deal with the scientific, logistical, and financial aspects of the group. Member and affiliate institutions, include academic cancer centers, and community-based oncology programs (through the cancer control program and the

community oncology program). Participants in the group from the member institutions include members from radiation oncology, medical oncology, surgical pathology, surgical oncology, gynecologic oncology, and other oncologic disciplines. Individual physicians, nurses, and data managers attend semiannual meetings, and between these participate in group activities via other meetings, telephone or mail communications. The RTOG Headquarters and the RTOG Statistical Center are located in Philadelphia, Pennsylvania. The American College of Radiology serves as the fiscal agent for the RTOG grants. Within the RTOG structure there is a series of committees, including standing committees, modality or scientific theme subcommittees, and disease site subcommittees. The RTOG organization is outlined in Figure 1 and Table 1. The RTOG’s statistical center collaborates with the RTOG investigators to provide efficient study design, careful monitoring of ongoing trials, timely and appropriate analysis of trials, and prompt reports of results. This collaboration is achieved through the assignment of a statistician to each modality, site subcommittee, and protocol. A system for quality control of protocol treatment delivery and clinical data has been established. The delivery of each treatment modality is scored in terms of compliance with the protocol design. The submitted clinical data are evaluated with respect to timeliness of the submission, accuracy, and completeness. Periodic institutional audits are done under the auspices of the Quality Control Committee to verify the validity of the clinical data as submitted to RTOG Headquarters. Extramural physics support for reviews is provided by the Radiologic Physics Center in Houston, Texas.

PROTOCOL

DEVELOPMENT

Phase I and II protocols, which involve new research themes in radiation oncology or in multimodality treatment, yield data on feasibility, toxicity, and preliminary efficacy. These studies are organized in new modality subcommittees (Table 1). Ideas generated from these Phase I and II studies, or from other sources of information, are subsequently tested in Phase III trials in disease specific sites, where they are compared to the current best therapy applied in clinical practice. These trials are under the auspices of the disease site subcommittees, which set priorities for the ideas to be tested. The major research themes are highlighted in Table 1 and organized as to disease sites in which they have been tested by Phase III studies. Trials are only undertaken if the patient accession can be completed within an appropriate time frame, if the endpoints can be reliably measured, and if meaningful improvements in treatment can be expected. Information regarding appropriate prognostic factors, which are used to stratify patients prior to randomization, comes from past analysis of patient groups in these disease-specific protocols as well as from other sources of information. The Research Strategy Committee is composed of all chairmen of other committees, the group’s scientific vice chairmen, group chairmen, and statisticians. All research ideas and protocols are centrally coordinated by this committee (Fig. 1). Case Accession The RTOG has continued to maintain a high level of case accession in the face of ever-increasing complexity of the protocols and decreased real dollar funding (Fig. 2).

Specific major achievements include: 1. Demonstrating increased survival with concomitant cisplatin and 5fluorouracil and moderate dose radiation therapy over high dose radiation therapy alone in localized, unresectable carcinoma of the esophagus; 2. demonstrating increased survival with extended-field external radiation therapy plus brachytherapy over standard, pelvic radiation therapy plus brachytherapy in moderately advanced carcinoma of the cervix; 3. investigating hyperfractionated radiation therapy with total doses 15% to 30% above standard fractionation; identifying appropriate total doses to compare with standard fractionation and other experimental treatments for non-small cell carcinomas of the lung, carcinomas of the head and neck, and malignant gliomas; 4. conducting Phase III trials directed at organ-preservation for carcinomas of the anal canal and bladder, and established the basis for such trials in carcinoma of the rectum and larynx/hypopharynx; 5. conducting large Phase III trials of hormonal therapy as adjuvants to radiation therapy for carcinoma of the prostate; 6. conducting Phase III trials of hypoxic radiation sen-

sitizing drug (SR 2508) for inoperable carcinomas of the head and neck; and, 7. identifying pretreatment characteristics which obscure efficacy of therapy and adopting strategies to allocate favorable patients to Phase III trials and unfavorable patients to pilot studies. The future clinical research plan of the RTOG is beyond the scope of this paper. Background information regarding recently closed or current protocols (Appendix B, C) can be solicited from the group’s headquarters. The RTOG represents an international resource which is making important contributions to the assessment of innovative treatment programs for cancer management. The group has acted as a forum for the discussion, testing, and implementation of the latest advances in radiation therapy. From this has come contemporary, optimal, standard treatment programs, the objective of which is to maximize the potential for cancer cure with minimal complications. The group has sought to implement basic radiation oncology data into clinical practice. The investigative efforts of the RTOG are leading to improved cancer control.
