## Edinburgh and the MRC chromosome group, 1959–1961
A 1956 paper by Baikie, on megaloblastic erythropoiesis in idiopathic acquired anemia, appeared in the *Scottish Medical Journal* with a Glasgow Royal Infirmary affiliation, which according to that paper marked the start of his Scottish career [7](https://doi.org/10.1177/003693305600101006). By 1959 he was among the authors of "Chromosome studies in human leukaemia" in *The Lancet*, published on 1 September 1959 in volume 2, pages 425–428 [1](https://europepmc.org/article/MED/13795820).
The work came from the Medical Research Council Group for Research on the General Effects of Radiation at the Western General Hospital, Edinburgh [2](https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(60)90077-5/fulltext). According to *The Lancet*, a further paper, "Chromosome Studies in Leukæmia", carried the same group affiliation [2](https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(60)90077-5/fulltext). In February 1961 the group published "Cytogenetic Studies in Chronic Myeloid Leukæmia and Acute Leukæmia Associated with Mongolism", a *Lancet* paper by members of the Western General Hospital group [8](https://doi.org/10.1016/s0140-6736(61)90001-0).
It was this Edinburgh group that proposed that the abnormal chromosome seen in chronic granulocytic leukemia be dubbed "the Philadelphia chromosome", the name under which it has been known since [6](https://haematologica.org/article/view/10546).
## Representative work
"Two Cases of Leukæmia and a Case of Sex-Chromosome Abnormality in the Same Sibship", published in *The Lancet* on 1 November 1961, reported multiple cases of leukemia and a sex-chromosome abnormality within a single family, evidence bearing on whether a predisposition to leukemia could run in a sibship alongside visible chromosome anomalies [3](https://doi.org/10.1016/s0140-6736(61)90964-3).
## Melbourne and St Vincent's Hospital, 1964–1969
From 1964 Baikie's papers carry the [University of Melbourne](https://www.edgepedia.org/university-of-melbourne). A 1964 *Lancet* item titled "The Philadelphia Chromosome" lists him as corresponding author from the university [9](https://doi.org/10.1016/s0140-6736(64)92946-0). His Melbourne base was the University of Melbourne Department of Medicine at St Vincent's Hospital, the affiliation printed on a 1965 *Lancet* paper on nucleoli and basophilia in lymphocytes, published 14 August 1965 [4](https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(65)90314-4/fulltext).
The Melbourne years combined chromosome analysis with enzyme assays. "Phosphohexokinase Activity of Erythrocytes in Mongolism, Another Possible Marker for Chromosome 21", published in *The Lancet* on 1 February 1965, proposed, according to the paper itself, raised red-cell phosphohexokinase as a biochemical marker for the extra chromosome 21 in [Down syndrome](https://www.edgepedia.org/down-syndrome) [10](https://doi.org/10.1016/s0140-6736(65)90007-3). In the same year he co-authored a *Nature* paper on mosaicism for trisomy 17–18 and trisomy 13–15 in man, published 1 September 1965 [11](https://doi.org/10.1038/2071419a0).
A paper received for publication on 28 December 1967, "Cytogenetic evolution and clonal proliferation in acute transformation of chronic granulocytic leukaemia", documented the appearance of cell lines of differing chromosomal constitution as chronic granulocytic leukemia transformed to an acute phase, a phenomenon the paper notes is common in acute leukemia [13](https://europepmc.org/backend/ptpmcrender.fcgi?accid=PMC2008234&blobtype=pdf).
Two Melbourne papers addressed treatment and the status of the [Philadelphia chromosome](https://www.edgepedia.org/philadelphia-chromosome) directly. According to "Methotrexate in Meningeal Leukæmia", published in *The Lancet* on 1 July 1967, methotrexate was used against leukaemic involvement of the meninges [14](https://doi.org/10.1016/s0140-6736(67)92328-8). And a 1965 *Nature* paper, "Chronic Granulocytic Leukaemia: Demonstration of the Philadelphia Chromosome in Cultures of Spleen Cells", published 30 October 1965, showed the abnormality in cultured spleen cells and stated that the Philadelphia chromosome is derived from a chromosome of pair 21 by loss of a variable proportion of the long arms [15](https://doi.org/10.1038/208497a0).
The question of whether that abnormality was inherited was settled in a 1969 paper in the *Australasian Annals of Medicine* on cytogenetic studies in familial leukaemias. In a man with chronic granulocytic leukemia whose mother had died of the same disease, the Philadelphia chromosome was identified in bone marrow cells and in 50 percent of the dividing cells of cultured peripheral blood during relapse, but no Ph1-positive cells were found in a culture of subcutaneous fibroblasts, so the abnormality could be assumed to be acquired and not inherited; a second family studied the same way gave the same answer, providing further evidence of the Philadelphia chromosome as an acquired cytogenetic anomaly [16](https://doi.org/10.1111/imj.1969.18.1.7).
## Later career at the Royal Hobart Hospital
By 1968 Baikie's affiliation was the Royal Hobart Hospital. A 1968 *Lancet* paper on splenic cultures in leukemia and septicaemia, which again demonstrated the Philadelphia chromosome in cultures of spleen cells, carries that affiliation [5](https://doi.org/10.1016/s0140-6736(68)92751-7). In 1973 a *Lancet* paper, "The Tasmanian Goitrogen", published with a Royal Hobart Hospital, Tasmania affiliation, moved to endocrine epidemiology and examined the cause of the goitre endemic in Tasmania [17](https://doi.org/10.1016/s0140-6736(73)91269-5).
## Place in the history of cancer cytogenetics
The Edinburgh group's work sits at the foundation of cancer cytogenetics. A 1960 abstract in *Science* described a recurrent chromosomal abnormality found in seven cases of chronic granulocytic leukemia, the first demonstration of a consistent chromosomal abnormality in a specific type of cancer; the Edinburgh cytogenetic research group, of which Baikie was part, proposed that the chromosome be dubbed "the Philadelphia chromosome" [6](https://haematologica.org/article/view/10546). Full identification of the abnormality awaited the banding techniques of the 1970s, which demonstrated that the Philadelphia chromosome is a reciprocal translocation between chromosomes 22 and 9 [6](https://haematologica.org/article/view/10546). According to *Chromosome studies in human leukaemia*, Baikie's own contribution to that story ran from the first Edinburgh chromosome surveys of 1959, through the Melbourne work that showed the abnormality in spleen-cell cultures and established it as acquired rather than inherited, to the Hobart years.
