Sublobar resections as good as lobectomy for stage IA GGO lung cancer?

The new USPSTF lung cancer screening guidelines are about to produce an enormous wave of abnormal chest CTs, with suspicious pulmonary nodules in millions of current and former U.S. smokers. Many will be surgically removed, and thousands of people will be saved from premature death from lung cancer. That’s great news — mostly. Less widely [... read more]

Can pulmonologists do their own on-site cytopathology during bronchoscopy?

On-site, intra-procedure cytopathologic examination of aspirated tissue during transbronchial needle aspiration (either by EBUS or “blind” approach) is probably helpful during bronchoscopy. Why wouldn’t it be? You’ve got a trained professional there to tell you when you’ve made the diagnosis and can stop taking biopsies. Diagnostic yield should go up, complications down. Randomized trials have [... read more]

Overdiagnosis rate with lung cancer screening CT is 18%

Low-dose CT screening reduced death from lung cancer by about 20% in the National Lung Screening Trial, and the U.S. Preventive Services Task Force signaled it would recommend CT screening for most people with a heavy smoking history. The Affordable Care Act stipulates that USPSTF-recommended screening tests be completely free to consumers, so lung cancer screening will [... read more]

Breath tests can accurately diagnose lung cancer

Diagnosing lung cancer without a biopsy may seem like science fiction, but breath testing to identify lung cancer has made steady gains in accuracy in recent years. A study abstract presented by Peter Mazzone et al at Chest 2013 in Chicago shows just how far one of the new technologies — volatile organic compound analysis [... read more]

Mild weight gain after quitting smoking outweighed by cessation's benefits

Weight Gain After Quitting Smoking Usually Mild, Harmless Nicotine is an anorexigen, or appetite suppressant. This “benefit” of cigarette smoking is no secret, certainly not to teenage girls, who in surveys report smoking to stay thin. Even among women smokers over age 40, more than half said they would not quit smoking if it meant they would [... read more]

How to manage lung cancer when resection is high risk

Management of Lung Cancer in High Surgical Risk Patients By Blair Westerly, MD We all hope that surgical resection is an option for our unfortunate patients diagnosed with lung cancer.  However, as a consequence of the epidemiology of stage I non-small cell lung cancer, the standard of care, lobectomy with systematic mediastinal lymph node evaluation, [... read more]

USPSTF Recommends Lung Cancer Screening CT; Obamacare Pays

USPSTF Endorses Lung Cancer Screening CT; New Standard of Care Begins Lung cancer screening CT took its most important step toward widespread implementation last week, when the U.S. Preventive Services Task Force (USPSTF) released a draft of its forthcoming recommendation that the 9 million U.S. people meeting entry criteria for the National Lung Screening Trial [... read more]

How to ration lung cancer screening CTs, rationally

Restrict Lung Cancer Screening CT To Highest-Risk People? The National Lung Screening Trial showed that 3 annual low-dose chest CT scans in people with heavy smoking histories (30+ pack-years) saved lives, reducing the risk of death from lung cancer by a relative 20% compared to screening with annual chest X-rays. With 160,000 lung cancer deaths [... read more]

Many people with metastatic lung cancer think radiation can cure

image: cancer.gov Patients With Metastatic Lung Cancer Often Believe Radiation Could Cure Among 384 patients with metastatic lung cancer who answered a survey, two in five expressed belief that radiation therapy was “very likely” or “somewhat likely” to cure them. Eighty percent thought radiation therapy would allow them to live longer, and only one-third admitted [... read more]

New lung cancer prediction tool promises better use of screening CT

New Prediction Model Selects Best Lung Cancer Screening Candidates In the National Lung Screening Trial (NLST), screening for lung cancer with low-dose chest CT scans resulted in a 20% reduction in death from lung cancer. The consumer-serving American Lung Association recommended outright that older people with heavy smoking histories should get lung cancer screening; leading [... read more]

How dangerous are ground glass nodules over time?

image: Radiology Assistant Ground-Glass Nodules: If Growing, Assume Cancer Blair Westerly, MD The more CT scans that are performed, the more ground-glass opacities (GGO’s) are seen and what to do with these abnormalities can be difficult to ascertain for clinicians. With the National Lung Cancer Screening Trial showing a mortality benefit from low dose CT [... read more]

Big Tobacco win: Feds to take breather in fight for scary cigarette labeling

Feds to Big Tobacco on Cigarette Labeling Fight: “Uncle!” The feds are admitting defeat for now in their fight for graphic, negative imagery to be displayed on all cigarette packaging and advertisements. Attorney General Eric Holder announced yesterday that the Justice Department will not ask the Supreme Court to reverse their loss in a federal [... read more]

PET scans often inaccurate; may deny curative surgery for lung cancer

The use of positron emission tomography — better known as PET scans — has grown dramatically over the past 15 years, thanks to their seemingly magical ability to identify foci of undetected metastatic cancer. But PET scans’ perceived high accuracy in diagnosing metastatic non-small cell lung cancer (NSCLC) — a published 94% sensitivity and 83% [... read more]

Bad news for IP guys? Incidental mediastinal lymphadenopathy may not need routine biopsy

(image: Wikipedia) With increasing use of chest CT, incidental mediastinal lymphadenopathy seems to be frequently discovered and subsequently biopsied using EBUS. The “if it’s enlarged, stick a needle in it” mantra is challenged by a paper by Stigt et al. 83 people (age ~59) with at least one incidentally discovered mediastinal lymph node > 1 [... read more]

ACCP, ATS only weakly recommend lung cancer CT screening, warn of harms

The American College of Chest Physicians (ACCP) has issued its long-awaited recommendations on lung cancer screening with chest CT — and far from a ringing endorsement of screening, they are conservative and subdued, emphasizing the potential risks of an uncontrolled approach to lung cancer screening in the general population. The American Society of Clinical Oncology [... read more]

American Lung Association recommends CT screening for lung cancer

The American Lung Association has become the largest advisory body to recommend lung cancer screening for high-risk people, advising nearly all people aged 55-74 with a 30+ pack-year smoking history (the entry criteria for the National Lung Screening Trial, or NLST) to undergo low-dose CT scanning to detect early lung cancer. The National Comprehensive Cancer Network, [... read more]

Pleural catheters equal to pleurodesis for dyspnea relief from malignant effusions (TIME2)

(image: Wikipedia) In the TIME2 randomized trial published in the June 13 2012 JAMA, indwelling pleural catheters and talc pleurodesis were equivalent at reducing dyspnea over the 6 weeks following the procedure among 106 patients with malignant pleural effusions. Most patients receiving pleural catheters required no hospital stays, and overall had fewer repeat procedures than those [... read more]

Let's be honest: quitting smoking usually does make you fatter

There’s no use in sugar-coating the truth: Nicotine is an appetite suppressant, and smoking prevents weight gain. Not wanting to gain weight is a common reason why body-obsessed teenage girls say they smoke–and as far as we know, they’re “right:” teens who smoke gain slightly less weight than teens who don’t. It’s also long been believed [... read more]

Moderate pot smokers' lung function better than nonsmokers

Smoking marijuana moderately over years is strongly associated with small improvements in lung function, even compared to people who have never smoked cigarettes or marijuana, according to a study in JAMA. But the popular news media and the study authors downplayed that finding of the study, apparently to avoid sending a pro-marijuana message. Mark Pletcher, [... read more]

New Trachea Grown, Transplanted In Two Men Paolo Macchiarini, Philipp Jungebluth et al report in Lancet their successful bioprosthetic trachea creation and transplantation in a 36-year old man in Sweden after a distal tracheal resection for recurrent primary tracheal cancer. The same group transplanted a bioengineered trachea into a 30-year old Baltimore man, who is [... read more]
