a brief history of radical mastectomy

leave a comment »

Dr William Halsted

Siddhartha Mukherjee is an oncologist, an academic and an astonishingly gifted writer and story-teller, in the Indian tradition of seemingly effortless, self-effacing wordsmiths. I read, and learned heaps from, his 2016 book The Gene a while back, and now I’m being educated by his first book The Emperor of all Maladies, a history of cancer. 

The book twists together different threads of cancer treatment in the modern era, most notably various forms of chemotherapy, and surgery. I’m focusing solely on surgery here, as it pertains to breast cancer, because it highlights the relation between experts (very predominantly male) and sufferers (exclusively female).

The term mastectomy is a bit of a mystery, at least to me. The suffix –ectomy is clear enough, meaning ‘cutting out’, or surgical removal, and ‘lumpectomy’ is a slightly dismissive term for the surgical removal of lumps (from the days when full-blown excision was king) . Maybe mastectomy refers to the removal of a mass of tissue, though why it wouldn’t be called massectomy or masectomy, and why it refers only to the breast, I don’t know. It has nothing to do with mast cells.

The radical mastectomy – the concept refers to ‘root’ as in rooting out, rather than quasi-political radicalism – is most associated with an American physician, William Halsted, though radical surgery in the treatment of cancer was far from unknown when Halsted began practising in the 1870s. Cancer at the time was recognised as the growth and spread of malignant tissue, at mysteriously varying rates, and the surgical removal of that tissue seemed the obvious response. Nineteenth century developments in anaesthesia helped to make the procedure more bearable for all, but operations in the US were often ad hoc and unsanitary. In the late 1870s Halsted made a trip to Europe, which radically changed his outlook and practice. He encountered and absorbed the ideas of various pioneers in surgery and anatomy, including Joseph Lister, Theodor Billroth, Richard von Volkmann and Hans Chiari, then returned to the US, and in the 1880s he quickly established a reputation for boldness and skill as a surgeon. Having become familiar with cocaine, which he recommended as an anaesthetic, he soon became addicted to the drug, which gave him seemingly boundless energy. He tried using morphine to kick the habit, and then found himself in a struggle with both drugs, but this barely damped his work-rate.

Hasted had become particularly interested in Volkmann’s surgical work on breast cancer, and noted that, though the surgeries became more extensive, the cancers returned. An English surgeon, Charles Moore, was experiencing the same problem. Moore’s painstaking analysis of the operations and the following relapses showed that malignant cells had begun to proliferate around the edges of previous surgeries. It seemed clear to him that the surgeries just weren’t extensive enough, and by limiting the surgery to the clearly evident cancerous tissue, and not widening the margins to ensure that the malignant region was properly cleaned out, surgeons were exercising ‘mistaken kindness’. Of course, the problem with this argument was that more radical surgery could itself be life-threatening as well as permanently disfiguring and debilitating. What was also not known at the time was the detailed mechanism of cancer’s metastatic spread throughout the body via the blood and lymph systems. However, this was a time when medical expertise tended to go unquestioned. Halsted and his surgical followers were considered heroes, and the delayed return of the cancers tended not to be dwelt on. The surgeons certainly did buy time for their patients, but often at great cost. Volkmann, for example, had taken breast surgery further by removing not just the breast but the muscle beneath it, the pectoralis minor, to try to ensure the complete removal of the cancer. Impressed, Halsted took things to the next level, cutting through the more vital pectoralis major, essentially killing off movement of the shoulder and arm. Radical mastectomy had now truly arrived, and was to become even more radical, with the collarbone and the group of lymph nodes beneath it becoming the next target, and it didn’t stop there, as cancer kept recurring. As Mukherjee describes it:

A macabre marathon was in progress. Halsted and his disciples would rather evacuate the entire contents of the body than be faced with cancer recurrences. In Europe, one surgeon evacuated three ribs and other parts of the rib cage and amputated a shoulder and a collarbone from a woman with breast cancer.

There were, of course, no female surgeons at this time, and precious few female doctors, and the male-female power imbalance was coupled with that of the expert and his suffering if not panicking victim to create a kind of juggernaut of largely unnecessary suffering. It took years to reverse this radicalising trend. Nowadays, radical mastectomies are very rarely performed, but with so many giants in the field – who often controlled the nature of clinical trials related to cancer – having earned their reputations through their surgical expertise, change was slow in coming, in spite of a gradual increase in often heroic dissenting voices. For example, Rachel Carson, the author of Silent Spring, refused to undergo a radical mastectomy, which would in any case have offered only brief respite as the cancer had already spread to her bones. Changing attitudes to experts and their secret and superior knowledge was of course a feature of the sixties and seventies, when the turning point really occurred. Developments in the field of course played their part. The knock-out blow for the procedure is largely associated, according to Mukherjee, with another surgeon, not unlike Halsted in energy and drive.

Bernard Fisher had been analysing the data of Halsted’s critics, notably Geoffrey Keynes in England and George Crile in the US, and became increasingly convinced, for a number of reasons, that radical mastectomy was a wrong-headed approach. In 1967, Fisher became the chair of a national consortium in the US, the National Surgical Adjuvant Breast and Bowel Project (NSABP), and began an uphill battle to run large-scale trials to test the efficacy of different treatments of breast cancer. Patients were reluctant to engage, and most surgeons were hostile. The process took years, but results were finally made public in 1981. Here’s Mukherjee’s summary.

The rates of breast cancer recurrence, relapse, death and distant caner metastasis were statistically identical among all three groups [i.e treated with radical mastectomy, with simple mastectomy, or with surgery followed by radiation]. The group treated with the radical mastectomy had paid heavily in morbidity, but accrued no benefits in survival, recurrence or mortality.

So. Richard Feynman once famously/notoriously said ‘science is the belief in the ignorance of experts. When someone says science teaches us such and such, s/he’s using the word incorrectly – science doesn’t teach us, experience teaches us.’ I agree. Science isn’t a person, let alone an expert person. Science is, to me, an open-ended set of methods based on experience. Experience creates new methods out of which new experiences are created, and we move on, trying to right the wrongs and to minimise the damage, while always maintaining our skepticism.
