Current commercial and public interests are not

aligned to answer these quest ions. The answers are

important for patient s but not for tjrug manufacturers,

which are reluctant to sponsor trials because of the

fear that their drug might turn out to be inferior to a

diverge, all too often clinical research produces

meaningless results that serve no one. Here is where

public funding must step in: we should not wait

another 30 years for the convergence of public and

industry interest s to get the answers patients need

now.

Alchemy, the safer cigarette, and Philip Morris

20 years ago Philip Morris, t he manufacturer of Marlboro

cigarettes, noted in its an nu al report to shareholders

that the company accounted for just 7% of worldwide

cigarette sales, but added determinedly that "since

our share of most internationa l cigarette markets is

still far below our US level, we have considerable room

for future growth".' The prophet ic rise in Philip Morris'

market share of current global cigarette sales to 15·6%

has culminated in the March spinoff of Philip Morris

International (PMI}.' This means that PMI, newly

headquartered in Lausanne, Switzerland, is now an

entirely separate corporation that is traded on the New

York Stock Exchange, as is Altria, which is the parent

entity of Philip Morris USA (as well as a new cigar

acquisit ion, John Middleton).

PMI is the world's most profitable publicly traded

tobacco company, with operations in 160 count ries.

Yet just 5% of PMl's profits are from Asia and Eastern

www.thelancet.com Vol 371 May 17, 2008

Europe, which account for 60% of international cigarette consumption.1 Now with a headquarters in Switzerland and thus with far less exposure than in the USA to tobacco-product litigation, federal and state regulations, antismoking activism, and strict prohibitions on public smoking, PMI is introducing a host of new cigarette products targeted at these

emerging markets."-1

The spinoff of PMI and its global marketing push would seem to contradict Philip Morris' carefully cultivated image of social responsibility in the USA in recent years, as epitomised by its breaking ranks with the rest of

the industry to support putative regulation of tobacco products by the Food and Drug Administration (FDA), by its advertising campaigns touting the company's charitable giving, and by the name-change of its parent

corporation to the altruistically sounding Altria.1·~ Could Philip Morris' makeover have diverted attention from the

move of most of the company's assets to a safe haven? The vestigial entity, Philip Morris USA, remains

America's dominant cigarette-maker by far, with a

50% share of a declining but still highly profitable market.

In Richmond, VA, USA, where it has consolidated all operations, the company has opened a US$350-million research centre that will employ 500 scientists, engineers, and technical staff. Chief executive officer Louis Camilleri

(whose masterminding of the company's expansion into

developing nations propelled him into its top job) has promised that the facility will be "dedicated to enhancing scientific research, developing new technologies and new products that might help address the harm caused by

smoking".'° With this tactic, the company may be count ing on

the public's short memory. Indeed, the gleaming Philip

Morris Center for Research and Technology is the tobacco giant's fourth such incarnation since the 1950s ostensibly aimed at eliminating the risks of smoking.

And Philip Morris' newly professed commitment to public health is reminiscent of the ignominious "Frank statem ent to cigarette smokers", a 1954 advertisement in major newspapers writ ten by the newly formed Tobacco Industry Research Committee (which included Philip Morris) after cigarette sales flattened on the heels of growing evidence that smoking caused lung cancer. "We accept an interest in people's health as a basic responsibility, paramoun t to every other consideration in our business", asserted the Committee, which

1•,ww.thclancot com Vol 371 May 17, 2008

pledged "aid and assistance to the research effort into

all phases of toba cco use and health"." Yet in the ensuing half-century, virtually all reports

of diseases caused by smoking were disputed by the

tobacco industry, which claimed that more research was needed.11 Only in 1999, confronting massive litigation, did Philip Morris acknowledge "the overwhelming medical and scientific consensus that cigarette smoking

causes lung cancer, heart disease, emphysema, and other serious diseases in smokers"." Meanwhile, as millions died from cigarette smoking, research funded by the tobacco industry resulted in a plethora of filters, "low

tar" products, "reduced emission" cigarettes, and "mild", "light", or "ultra-light" brands, none of which has made smoking safer.'',.,~

The hoopla over Philip Morris' new centre (the

company has even advertised for researchers in Science} is synergistic with its backing of the bill to

permit FDA regulation of tobacco products . The imprimatur of the FDA would provide much-needed credibility for research initiated by Philip Morris now that the company has been found by Federal

Judge Gladys Kessler (Aug 17, 2006} to have violated civil racketeer ing laws over a SO-year period by deceiving the public about the dangers of smoking, by manipulating the design of cigarettes, and by

suppressing research.'"

A Frank Statement To Cigarette Smokers

I

RECENT REPORTS on experiments wilh mice have given wide publicity lo a theory lhnt cignreue smoking is in some wny linked wi1h lung cnnccr in human beings.

Allhough conducted by doctors of professional standing, these cxperimcnls nre nol regarded ns conch.wive in the field ofcnnccr rc!Jcurch. However, we do not bclir;ve resulls nrc inconclueivc, should be disrcgartlcd or lightly dismissed. At lhc same lime, we feel ii is in lhc public inlercsl lo call nllenlion to U1e foci U1nt eminent doctors and research ocienlists hnvc publicly queslioncd the claimed significnncc of lhc,e experiments.

I Comment

Since existing brands will remain essentially

untouched by the FIJA bill, Marlboro, with a 41% US

market share (or more than fivC:' times that of its nearest

competitor), is unlikely to experience a significant

sales decline. Philip Morris will thu s continue to have

deep pockets to promote the chimera that research

will make smoking safer. To this end, the company

is increasing ties to academic medical centres, such

as the University of Virginia, to which it has given

~25 million." The search for a safer cigarette is akin to alchemists

seeking to turn lead into gold. Perpetuat ing the myth to

the medical community and the public at large may also

be worth its weight in gold to Philip_Morris.

Trastuzumab: possible publication bias

Publication bias is of increasing concern, entrenching the

use of inferior t reatments.' This concern now extends to

adjuvant trastuzumab (Herceptin) in women with early

breast cancer that is ERBB2 (HER2) positive, because a

key clinical trial' has been only selectively published.3 As

such, patients are being given an important treatme nt

sequence that may be much less effective than currently

thoug ht."-1

Adjuvant trastuzuma b can be given in two main

sequences: concurrent ly with or sequentially after other

chemotherapy.6 Sequential t reat ment is licensed,' ·1 is

standard practice, and is the publicly funded regimen

in many countrie s, such as most of Europe (UK

included). One randomised trial (out of six relevant

trials'•·R), by the North Central Cancer Treatment Group

(NCCTG), trial NCCTG-N9831,' has studied sequentia l

and concurrent treatment s head -to-head, together

with a control or usual-care group . However, although

this three-group study has important implications

for how best to use trastuzumab , it has only been

part ly published. Data from the 985 women given

12-month sequent ial trastuzumab in this study are in

effect missing,••1 despite publication of data from the

12-mont h concurrent and control groups of the same

trial nearly 3 years ago.9

Interim results for all three groups of t he NCCTG trial

were presented orally in 2005 at the American Society

of Clinical Oncology's annual meeting.' After 1·5 years

of median follow-up, sequential trastuzumab gave a

comparatively' small 13% relative reduction in disease

events compared with usual care-with a reasonable

chance of being no bett er than the cont rol group (hazard

ratio 0-87, 95% Cl 0-67-1·13). Conversely, concurrent

trastuzumab was significantly more effective than

sequential therapy, reducing disease events by a third

(0-64, 0-46-0 -91).'

Soon after, Romond and colleagues published the

concurrent and cont rol group results from the I\JCCTG
