Subseries contains files and graphs of the clinical courses of patients with leukemia. These graphs were kept by the Acute Leukemia Service from about 1971 to 1983. They represent clinical record keeping in the pre-computer era. This type of graphic representation was discontinued in 1983 in favour of computer-based record keeping. Records were transferred as binders titled as follows: Leukemia Protocols, Leukemia – Active A-L, Leukemia – Active M-Z, Acute Leukemia – Deceased A-E, Acute Leukemia – Deceased F-H [includes I-Z], Leukemia File Worksheets : AA2-AA3 : May 1977 – Dec. 1979, and Miscellaneous Patients.

The Protocols binder contained copies of treatment protocols used by the clinical leukemia service during this period. Patients who were included in the binders labeled Leukemia-Active were on active treatment at the time this record-keeping was discontinued. Records of patients who had died had been removed from the active binders. The binder labeled “miscellaneous patients” referred to patients not treated with standard PMH protocols or who were admitted to the service after having received some amount of treatment from another hospital.

The first five files in the subseries contain general information regarding the Clinical Leukemia Service at OCI/PMH from the period 1989-1990. File 5A1.138 includes planning papers from 1975 regarding the development of a leukemia service at the Princess Margaret Hospital.

Series consists of minutes of the Committee on Informed Consent and the Special Committee on Consent, research and presentation slides, research and lecture notes, preliminary architectural drawings of the University Avenue site, and annual reports from the Ontario Institute of Radiotherapy, all accumulated by Dr. Richard Hasselback of the Department of Medicine. Series reflects the varied responsibilities and interests of the clinical staff. Files 5.6 to 5.12 may originally have been before file 5.1 but were in the present order when they arrived at the Archives.

There is one subseries:
5A1: Leukemia Service records.

Richards, President of the Ontario Institute of Radiotherapy; cancer statistics and annual reports from the Ontario Institute of Radiotherapy; and minutes of the National Cancer Institute. Records reflect the varied administrative, teaching and research activities undertaken by Dr. Ash while Director of the Ontario Cancer Institute and contain files relating to his previous and concurrent positions as radiologist under Dr. Gordon E. Richards at Toronto General Hospital(1940-1949), senior radiologist at the Toronto General Hospital (from 1949), Professor of Radiotherapy at the University of Toronto and Radiotherapist in Chief to The Toronto General Hospital. Records do not include files from the offices of subsequent holders of this position. The statistics files include cancer statistics from 1924 to 1956. Files 2.50-2.57 relate to the Ontario Cancer Treatment and Research Foundation. Files 2.84-2.108 are the files of the President of the Ontario Institute of Radiotherapy which were created at the Toronto General Hospital and probably accumulated by Dr. Ash in 1949 when he was appointed Senior Radiologist at the Toronto General Hospital. Dr. Ash probably brought these files with him to the Ontario Cancer Institute when he became Director. Files have been arranged as close as possible to the order in which they were found, although the original order had probably been tampered with prior to their transfer to the Archives.

Gaps exist in the records between 1926 and 1934, 1966 and 1969, and 1969 and 1975.

Files 1B.12 - 1B.57 were originally in unlabelled sleeves and loose piles and have been kept in the same order as they were found. No attempt has been made to impose an order on them.
