The Emperor of All Maladies

Between 1891 and 1907—in the sixteen hectic years that stretched from the tenuous debut of the radical mastectomy in Baltimore to its center-stage appearances at vast surgical conferences around the nation—the quest for a cure for cancer took a great leap forward and an equally great step back. Halsted proved beyond any doubt that massive, meticulous surgeries were technically possible in breast cancer. These operations could drastically reduce the risk for the local recurrence of a deadly disease. But what Halsted could not prove, despite his most strenuous efforts, was far more revealing. After nearly two decades of data gathering, having been levitated, praised, analyzed, and reanalyzed in conference after conference, the superiority of radical surgery in “curing” cancer still stood on shaky ground. More surgery had just not translated into more effective therapy.

Yet all this uncertainty did little to stop other surgeons from operating just as aggressively. “Radicalism” became a psychological obsession, burrowing its way deeply into cancer surgery. Even the word radical was a seductive conceptual trap. Halsted had used it in the Latin sense of “root” because his operation was meant to dig out the buried, subterranean roots of cancer. But radical also meant “aggressive,” “innovative,” and “brazen,” and it was this meaning that left its mark on the imaginations of patients. What man or woman, confronting cancer, would willingly choose nonradical, or “conservative,” surgery?

Indeed, radicalism became central not only to how surgeons saw cancer, but also in how they imagined themselves. “With no protest from any other quarter

(#litres_trial_promo) and nothing to stand in its way, the practice of radical surgery,” one historian wrote, “soon fossilized into dogma.” When heroic surgery failed to match its expectations, some surgeons began to shrug off the responsibility of a cure altogether. “Undoubtedly, if operated upon properly

(#litres_trial_promo) the condition may be cured locally, and that is the only point for which the surgeon must hold himself responsible,” one of Halsted’s disciples announced at a conference in Baltimore in 1931. The best a surgeon could do, in other words, was to deliver the most technically perfect operation. Curing cancer was someone else’s problem.

This trajectory toward more and more brazenly aggressive operations—“the more radical the better”

(#litres_trial_promo)—mirrored the overall path of surgical thinking of the early 1930s. In Chicago, the surgeon Alexander Brunschwig devised an operation

(#litres_trial_promo) for cervical cancer, called a “complete pelvic exenteration,” so strenuous and exhaustive that even the most Halstedian surgeon needed to break midprocedure to rest and change positions. The New York surgeon George Pack was nicknamed Pack the Knife

(#litres_trial_promo) (after the popular song “Mack the Knife”), as if the surgeon and his favorite instrument had, like some sort of ghoulish centaur, somehow fused into the same creature.

Cure was a possibility now flung far into the future. “Even in its widest sense,”

(#litres_trial_promo) an English surgeon wrote in 1929, “the measure of operability depend[s] on the question: ‘Is the lesion removable?’ and not on the question: ‘Is the removal of the lesion going to cure the patient?’ ” Surgeons often counted themselves lucky if their patients merely survived these operations. “There is an old Arabian proverb,”

(#litres_trial_promo) a group of surgeons wrote at the end of a particularly chilling discussion of stomach cancer in 1933, “that he is no physician who has not slain many patients, and the surgeon who operates for carcinoma of the stomach must remember that often.”

To arrive at that sort of logic—the Hippocratic oath turned upside down—demands either a terminal desperation or a terminal optimism. In the 1930s, the pendulum of cancer surgery swung desperately between those two points. Halsted, Brunschwig, and Pack persisted with their mammoth operations because they genuinely believed that they could relieve the dreaded symptoms of cancer. But they lacked formal proof, and as they went further up the isolated promontories of their own beliefs, proof became irrelevant and trials impossible to run. The more fervently surgeons believed in the inherent good of their operations, the more untenable it became to put these to a formal scientific trial. Radical surgery thus drew the blinds of circular logic around itself for nearly a century.

The allure and glamour of radical surgery overshadowed crucial developments in less radical surgical procedures for cancer that were evolving in its penumbra. Halsted’s students fanned out to invent new procedures to extirpate cancers. Each was “assigned” an organ. Halsted’s confidence in his heroic surgical training program was so supreme that he imagined his students capable of confronting and annihilating cancer in any organ system. In 1897, having intercepted a young surgical resident, Hugh Hampton Young, in a corridor at Hopkins, Halsted asked him to become the head of the new department of urological surgery. Young protested that he knew nothing about urological surgery. “I know you didn’t know anything,”

(#litres_trial_promo) Halsted replied curtly, “but we believe that you can learn”—and walked on.

Inspired by Halsted’s confidence, Young delved into surgery for urological cancers—cancers of the prostate, kidney, and bladder. In 1904, with Halsted as his assistant

(#litres_trial_promo), Young successfully devised an operation for prostate cancer by excising the entire gland. Although called the radical prostatectomy in the tradition of Halsted, Hampton’s surgery was rather conservative by comparison. He did not remove muscles, lymph nodes, or bone. He retained the notion of the en bloc removal of the organ from radical surgery, but stopped short of evacuating the entire pelvis or extirpating the urethra or the bladder. (A modification of this procedure is still used to remove localized prostate cancer, and it cures a substantial portion of patients with such tumors.)

Harvey Cushing, Halsted’s student and chief surgical resident, concentrated on the brain. By the early 1900s, Cushing had found ingenious ways to surgically extract brain tumors, including the notorious glioblastomas—tumors so heavily crisscrossed with blood vessels that they could hemorrhage any minute, and meningiomas wrapped like sheaths around delicate and vital structures in the brain. Like Young, Cushing inherited Haslted’s intaglio surgical technique—“the slow separation of brain from tumor,

(#litres_trial_promo) working now here, now there, leaving small, flattened pads of hot, wrung-out cotton to control oozing”—but not Halsted’s penchant for radical surgery. Indeed Cushing found radical operations on brain tumors not just difficult, but inconceivable: even if he desired it, a surgeon could not extirpate the entire organ.

In 1933, at the Barnes Hospital

(#litres_trial_promo) in St. Louis, yet another surgical innovator, Evarts Graham, pioneered an operation to remove a lung afflicted with cancer by piecing together prior operations that had been used to remove tubercular lungs. Graham, too, retained the essential spirit of Halstedian surgery: the meticulous excision of the organ en bloc and the cutting of wide margins around the tumor to prevent local recurrences. But he tried to sidestep its pitfalls. Resisting the temptation to excise more and more tissue—lymph nodes throughout the thorax, major blood vessels, or the adjacent fascia around the trachea and esophagus—he removed just the lung, keeping the specimen as intact as possible.

Even so, obsessed with Halstedian theory and unable to see beyond its realm, surgeons sharply berated such attempts at nonradical surgery. A surgical procedure

(#litres_trial_promo) that did not attempt to obliterate cancer from the body was pooh-poohed as a “makeshift operation.” To indulge in such makeshift operations was to succumb to the old flaw of “mistaken kindness” that a generation of surgeons had tried so diligently to banish.

We have found in [

(#litres_trial_promo)X-rays] a cure for the malady.

—Los Angeles Times, April 6, 1902

By way of illustration

(#litres_trial_promo) [of the destructive power of X-rays]

(#litres_trial_promo) let us recall that nearly all pioneers in the medical X-ray laboratories in the United States died of cancers induced by the burns.

—The Washington Post, 1945

In late October 1895, a few months after Halsted had unveiled the radical mastectomy in Baltimore, Wilhelm Röntgen, a lecturer at the Würzburg Institute in Germany, was working with an electron tube—a vacuum tube that shot electrons from one electrode to another—when he noticed a strange leakage. The radiant energy was powerful and invisible, capable of penetrating layers of blackened cardboard and producing a white phosphorescent glow on a barium screen accidentally left on a bench in the room.

Röntgen whisked his wife, Anna, into the lab and placed her hand between the source of his rays and a photographic plate. The rays penetrated through her hand and left a silhouette of her finger bones and her metallic wedding ring on the photographic plate—the inner anatomy of a hand seen as if through a magical lens. “I have seen my death,” Anna said—but her husband saw something else: a form of energy so powerful that it could pass through most living tissues. Röntgen called his form of light X-rays.

At first, X-rays were thought to be an artificial quirk of energy produced by electron tubes. But in 1896, just a few months after Röntgen’s discovery, Henri Becquerel, the French chemist, who knew of Röntgen’s work, discovered that certain natural materials—uranium among them—autonomously emitted their own invisible rays with properties similar to those of X-rays. In Paris, friends of Becquerel’s, a young physicist-chemist couple named Pierre and Marie Curie, began to scour the natural world for even more powerful chemical sources of X-rays. Pierre and Marie (then Maria Skłodowska, a penniless Polish immigrant living in a garret in Paris) had met at the Sorbonne and been drawn to each other because of a common interest in magnetism. In the mid-1880s, Pierre Curie had used minuscule quartz crystals to craft an instrument called an electrometer, capable of measuring exquisitely small doses of energy. Using this device, Marie had shown that even tiny amounts of radiation emitted by uranium ores could be quantified. With their new measuring instrument for radioactivity, Marie and Pierre began hunting for new sources of X-rays. Another monumental journey of scientific discovery was thus launched with measurement.

In a waste ore called pitchblende, a black sludge that came from the peaty forests of Joachimsthal in what is now the Czech Republic, the Curies found the first signal of a new element—an element many times more radioactive than uranium. The Curies set about distilling the boggy sludge to trap that potent radioactive source in its purest form. From several tons of pitchblende, four hundred tons of washing water, and hundreds of buckets of distilled sludge waste, they finally fished out one-tenth of a gram of the new element in 1902. The metal lay on the far edge of the periodic table, emitting X-rays with such feverish intensity that it glowered with a hypnotic blue light in the dark, consuming itself. Unstable, it was a strange chimera between matter and energy—matter decomposing into energy. Marie Curie called the new element radium, from the Greek word for “light.”

Radium, by virtue of its potency, revealed a new and unexpected property of X-rays: they could not only carry radiant energy through human tissues, but also deposit energy deep inside tissues. Röntgen had been able to photograph his wife’s hand because of the first property: his X-rays had traversed through flesh and bone and left a shadow of the tissue on the film. Marie Curie’s hands, in contrast, bore the painful legacy of the second effect: having distilled pitchblende into a millionth part for week after week in the hunt for purer and purer radioactivity, the skin in her palm had begun to chafe and peel off in blackened layers, as if the tissue had been burnt from the inside. A few milligrams of radium left in a vial in Pierre’s pocket scorched through the heavy tweed of his waistcoat and left a permanent scar on his chest. One man who gave “magical” demonstrations

(#litres_trial_promo) at a public fair with a leaky, unshielded radium machine developed swollen and blistered lips, and his cheeks and nails fell out. Radiation would eventually burn into Marie Curie’s bone marrow, leaving her permanently anemic.

It would take biologists decades to fully decipher the mechanism that lay behind these effects, but the spectrum of damaged tissues—skin, lips, blood, gums, and nails—already provided an important clue: radium was attacking DNA. DNA is an inert molecule, exquisitely resistant to most chemical reactions, for its job is to maintain the stability of genetic information. But X-rays can shatter strands of DNA or generate toxic chemicals that corrode DNA. Cells respond to this damage by dying or, more often, by ceasing to divide. X-rays thus preferentially kill the most rapidly proliferating cells in the body, cells in the skin, nails, gums, and blood.

This ability of X-rays to selectively kill rapidly dividing cells did not go unnoticed—especially by cancer researchers. In 1896, barely a year after Röntgen

(#litres_trial_promo) had discovered his X-rays, a twenty-one-year-old Chicago medical student, Emil Grubbe, had the inspired notion of using X-rays to treat cancer. Flamboyant, adventurous, and fiercely inventive, Grubbe had worked in a factory in Chicago that produced vacuum X-ray tubes, and he had built a crude version of a tube for his own experiments. Having encountered X-ray-exposed factory workers with peeling skin and nails—his own hands had also become chapped and swollen from repeated exposures—Grubbe quickly extended the logic of this cell death to tumors.

On March 29, 1896, in a tube factory on Halsted Street (the name bears no connection to Halsted the surgeon) in Chicago, Grubbe began to bombard Rose Lee, an elderly woman with breast cancer, with radiation using an improvised X-ray tube. Lee’s cancer had relapsed after a mastectomy, and the tumor had exploded into a painful mass in her breast. She had been referred to Grubbe as a last-ditch measure, more to satisfy his experimental curiosity than to provide any clinical benefit. Grubbe looked through the factory for something to cover the rest of the breast, and finding no sheet of metal, wrapped Lee’s chest in some tinfoil that he found in the bottom of a Chinese tea box. He irradiated her cancer every night for eighteen consecutive days. The treatment was painful—but somewhat successful. The tumor in Lee’s breast ulcerated, tightened, and shrank, producing the first documented local response in the history of X-ray therapy. A few months after the initial treatment, though, Lee became dizzy and nauseated. The cancer had metastasized to her spine, brain, and liver, and she died shortly after. Grubbe had stumbled on another important observation: X-rays could only be used to treat cancer locally, with little effect on tumors that had already metastasized.* (#litres_trial_promo)

Inspired by the response, even if it had been temporary, Grubbe began using X-ray therapy to treat scores of other patients with local tumors. A new branch of cancer medicine, radiation oncology, was born, with X-ray clinics mushrooming up in Europe and America. By the early 1900s, less than a decade after Röntgen’s discovery, doctors waxed ecstatic about the possibility of curing cancer with radiation. “I believe this treatment is an absolute cure

(#litres_trial_promo) for all forms of cancer,” a Chicago physician noted in 1901. “I do not know what its limitations are.”

With the Curies’ discovery of radium in 1902, surgeons could beam thousandfold more powerful bursts of energy on tumors. Conferences and societies on high-dose radiation therapy were organized in a flurry of excitement. Radium was infused into gold wires and stitched directly into tumors, to produce even higher local doses of X-rays. Surgeons implanted radon pellets into abdominal tumors. By the 1930s and ’40s, America had a national surplus of radium, so much so that it was being advertised for sale to laypeople

(#litres_trial_promo) in the back pages of journals. Vacuum-tube technology advanced in parallel; by the mid-1950s variants of these tubes could deliver blisteringly high doses of X-ray energy into cancerous tissues.

Radiation therapy catapulted cancer medicine into its atomic age—an age replete with both promise and peril. Certainly, the vocabulary, the images, and the metaphors bore the potent symbolism of atomic power unleashed on cancer. There were “cyclotrons” and “supervoltage rays” and “linear accelerators” and “neutron beams.” One man was asked to think of his X-ray therapy as “millions of tiny bullets of energy.”

(#litres_trial_promo) Another account of a radiation treatment is imbued with the thrill and horror of a space journey: “The patient is put on a stretcher

(#litres_trial_promo) that is placed in the oxygen chamber. As a team of six doctors, nurses, and technicians hover at chamber-side, the radiologist maneuvers a betatron into position. After slamming shut a hatch at the end of the chamber, technicians force oxygen in. After fifteen minutes under full pressure . . . the radiologist turns on the betatron and shoots radiation at the tumor. Following treatment, the patient is decompressed in deep-sea-diver fashion and taken to the recovery room.”

Stuffed into chambers, herded in and out of hatches, hovered upon, monitored through closed-circuit television, pressurized, oxygenated, decompressed, and sent back to a room to recover, patients weathered the onslaught of radiation therapy as if it were an invisible benediction.

And for certain forms of cancer, it was a benediction. Like surgery, radiation was remarkably effective at obliterating locally confined cancers. Breast tumors were pulverized with X-rays. Lymphoma lumps melted away. One woman with a brain tumor
