Rak płuca
Diagnostyka i diagnoza

Rak płuca stanowi drugą najczęstszą postać nowotworu u obu płci w USA i pozostaje główną przyczyną zgonów onkologicznych globalnie. Wczesne wykrycie, szczególnie za pomocą corocznych badań przesiewowych niskodawkową tomografią komputerową (LDCT), jest kluczowe dla poprawy rokowania, zwiększając 5-letnie przeżycie do ponad 75% w stadium IA. Aktualne wytyczne USPSTF rekomendują LDCT u osób w wieku 50-80 lat z historią palenia ≥20 paczkolat, które obecnie palą lub rzuciły palenie w ciągu ostatnich 15 lat. Badanie LDCT trwa około 10-15 minut i pozwala na wykrycie zmian nowotworowych we wczesnym stadium, zmniejszając śmiertelność o 20-25% w porównaniu do standardowego RTG klatki piersiowej. Przerwanie badań zaleca się po 81. roku życia, 15 latach abstynencji od palenia lub w przypadku poważnych schorzeń ograniczających przeżycie lub możliwość leczenia chirurgicznego.

Diagnostyka raka płuca

Rak płuca jest drugą najczęstszą postacią nowotworu u mężczyzn i kobiet w Stanach Zjednoczonych, jednak pozostaje wiodącą przyczyną zgonów związanych z nowotworami zarówno w USA, jak i na całym świecie 12. Wczesne rozpoznanie tego nowotworu ma kluczowe znaczenie dla rokowania pacjenta. Badania przesiewowe w kierunku raka płuca są wykonywane w celu wykrycia choroby, zanim pojawią się jakiekolwiek objawy, co może pomóc w znalezieniu raka we wczesnym stadium, kiedy łatwiej jest go leczyć 3.

Badania przesiewowe w kierunku raka płuca

Najczęstszą metodą badań przesiewowych w kierunku raka płuca jest niskodawkowa tomografia komputerowa (LDCT). Badanie to wykorzystuje technologię tomografii komputerowej, która emituje niską dawkę promieniowania w celu stworzenia szczegółowych obrazów płuc 45. W przeciwieństwie do standardowych zdjęć rentgenowskich klatki piersiowej, które nie wykazały skuteczności w zmniejszaniu śmiertelności z powodu raka płuca, coroczne badania LDCT u osób z grupy wysokiego ryzyka mogą pomóc zmniejszyć ryzyko zgonu z powodu tego nowotworu 6.

Badania wykazały, że skrining przy użyciu niskodawkowej tomografii komputerowej może zmniejszyć śmiertelność z powodu raka płuca nawet o 20-25% w porównaniu do badań przy użyciu standardowych zdjęć rentgenowskich klatki piersiowej 78. Wykrycie raka płuca we wczesnym stadium zwiększa szanse na przeżycie pięcioletnie do ponad 75% w przypadku raka w stadium IA 9.

Wskazania do badań przesiewowych

Obecnie badania przesiewowe w kierunku raka płuca zalecane są tylko osobom o podwyższonym ryzyku zachorowania na raka płuca. Według aktualnych wytycznych U.S. Preventive Services Task Force (USPSTF), coroczne badania przesiewowe przy użyciu niskodawkowej tomografii komputerowej zalecane są dla osób, które spełniają następujące kryteria:

  • Wiek 50-80 lat 1011
  • Obecnie palą papierosy lub przestali palić w ciągu ostatnich 15 lat 1213
  • Mają historię palenia wynoszącą co najmniej 20 paczkolat (liczba paczek papierosów wypalanych dziennie pomnożona przez liczbę lat palenia) 1415

Badania przesiewowe powinny być zaprzestane, gdy osoba:

  • Osiągnie wiek 81 lat
  • Nie paliła przez co najmniej 15 lat
  • Rozwinie problem zdrowotny, który znacznie ogranicza oczekiwaną długość życia lub możliwość/gotowość do poddania się operacji płucnej 1617

Procedura badania przesiewowego LDCT

Badanie przesiewowe LDCT jest szybkie i bezbolesne. Podczas badania pacjent leży na plecach na stole do badań, który powoli przesuwa się przez urządzenie, a pacjent wstrzymuje oddech na kilka sekund podczas wykonywania każdego skanu (10 sekund lub mniej) 18. Całe badanie trwa zwykle około 10-15 minut 19.

Pierwsze badanie przesiewowe LDCT jest znane jako badanie bazowe. Jeśli nie zostanie wykryty żaden guzek podczas tego badania, kolejne badanie powinno być wykonane po 12 miesiącach, a następnie co 12 miesięcy 20.

Korzyści i ryzyko związane z badaniami przesiewowymi

Główną korzyścią z badań przesiewowych w kierunku raka płuca jest wykrycie nowotworu we wczesnym stadium, co zmniejsza ryzyko zgonu z jego powodu 21. Badania przesiewowe mogą pomóc w identyfikacji osób o wysokim ryzyku zachorowania na raka płuca oraz umożliwić wczesną interwencję, co prowadzi do lepszych wskaźników przeżycia i poprawy długoterminowego rokowania 22.

Jednak badania przesiewowe w kierunku raka płuca wiążą się również z pewnymi ryzykami:

  • Wyniki fałszywie dodatnie – badanie może sugerować obecność raka płuca, gdy w rzeczywistości nie ma nowotworu. Może to prowadzić do niepotrzebnego lęku i dodatkowych testów 2324
  • Nadrozpoznawalność – badanie może wykryć przypadki raka, które nigdy nie spowodowałyby problemów zdrowotnych pacjenta 2526
  • Ekspozycja na promieniowanie – badania LDCT wiążą się z ekspozycją na niskie dawki promieniowania 27

Ważne jest, aby omówić korzyści i ryzyko związane z badaniami przesiewowymi ze swoim lekarzem przed podjęciem decyzji o ich wykonaniu 28.

Diagnostyka raka płuca po badaniu przesiewowym

Jeśli badanie przesiewowe LDCT wykaże nieprawidłowości w płucach, konieczne będą dalsze testy w celu potwierdzenia lub wykluczenia raka płuca 29. Proces diagnostyczny raka płuca obejmuje kilka etapów, w tym dodatkowe badania obrazowe, biopsje oraz badania funkcjonalne, które mają na celu rozpoznanie typu nowotworu oraz określenie jego zaawansowania 30.

Badania obrazowe

Badania obrazowe są kluczowym narzędziem w diagnostyce raka płuca. Pozwalają one lekarzom zobaczyć wewnętrzną strukturę płuc i okolicznych tkanek, pomagając w identyfikacji podejrzanych zmian 31. Do najczęściej stosowanych badań obrazowych należą:

  • Tomografia komputerowa (CT) – dostarcza szczegółowych obrazów płuc, umożliwiając określenie wielkości, kształtu i lokalizacji guza. CT może wykryć mniejsze zmiany niż standardowe zdjęcie rentgenowskie 3233
  • Pozytonowa tomografia emisyjna (PET) – wykorzystuje radioaktywnie znakowaną glukozę, która gromadzi się w komórkach nowotworowych. Badanie PET może pokazać, czy rak rozprzestrzenił się poza płuca 3435
  • Rezonans magnetyczny (MRI) – wykorzystuje fale radiowe i silne pola magnetyczne do tworzenia szczegółowych obrazów tkanek miękkich. MRI jest często stosowany do oceny, czy rak płuca rozprzestrzenił się do mózgu 3637

Biopsja

Biopsja jest procedurą, która polega na pobraniu próbki tkanki lub płynu z podejrzanego obszaru w celu zbadania jej pod mikroskopem 38. Jest to ostateczny krok w potwierdzeniu diagnozy raka płuca. Istnieje kilka metod wykonywania biopsji:

  • Bronchoskopia – procedura, podczas której cienki, giętki przewód z kamerą (bronchoskop) jest wprowadzany przez nos lub usta do dróg oddechowych w celu pobrania próbki tkanki 3940
  • Biopsja igłowa – cienka igła jest wprowadzana przez skórę do płuca, często pod kontrolą CT lub USG, w celu pobrania próbki tkanki 4142
  • Torakocenteza – procedura, podczas której lekarz usuwa płyn z przestrzeni wokół płuc w celu sprawdzenia, czy zawiera on komórki nowotworowe 4344
  • Ultrasonografia wewnątrzoskrzelowa (EBUS) – bronchoskop wyposażony w sondę ultradźwiękową pozwala na obrazowanie i biopsję węzłów chłonnych znajdujących się w pobliżu dróg oddechowych 4546
  • Torakoskopia – procedura chirurgiczna, podczas której lekarz wprowadza torakoskop (cienkie urządzenie wyposażone w kamerę) do klatki piersiowej przez małe nacięcie, aby zbadać płuca i pobrać próbki tkanki 47

Badania cytologiczne

W ramach diagnostyki raka płuca wykonuje się również badania cytologiczne, które polegają na analizie komórek pod mikroskopem w celu wykrycia komórek nowotworowych. Do badań cytologicznych należą:

  • Cytologia plwociny – badanie plwociny (wydzieliny odkrztuszanej z płuc) pod mikroskopem w celu wykrycia komórek nowotworowych 4849
  • Badanie płynu opłucnowego – analiza płynu pobranego z przestrzeni wokół płuc w celu wykrycia komórek nowotworowych 50

Badania molekularne i biomarkerowe

W przypadku raka płuca, szczególnie niedrobnokomórkowego (NSCLC), lekarze często badają próbki pobrane podczas biopsji w kierunku specyficznych zmian genetycznych w komórkach nowotworowych, które mogą wskazywać na możliwość zastosowania terapii celowanej 51.

Badanie biomarkerów nowotworowych, zwane również testowaniem molekularnym lub genomowym, polega na poszukiwaniu zmian w DNA guza 52. Wyniki tych badań mogą pomóc w określeniu, które opcje leczenia będą najbardziej skuteczne dla danego pacjenta.

Obecnie istnieją zatwierdzone przez FDA metody leczenia raka płuca dla guzów wykazujących nieprawidłowości w genach EGFR, ALK, ROS1, BRAFV600E, MET, RET, KRAS, HER2, NTRK i NRG1 53. Poziomy PD-L1 są również badane, aby określić, czy pacjent może odnieść korzyść z immunoterapii.

Ocena stopnia zaawansowania

Po potwierdzeniu diagnozy raka płuca, kolejnym krokiem jest określenie stopnia zaawansowania nowotworu. Ocena ta pomaga lekarzom określić, jak daleko rozprzestrzenił się rak i jakie są najlepsze opcje leczenia 54.

Do oceny stopnia zaawansowania stosuje się system TNM (Tumor – guz, Node – węzły chłonne, Metastasis – przerzuty) 5556. Stopnie zaawansowania raka płuca wahają się od 1 do 4, gdzie najniższa liczba oznacza, że nowotwór jest mały i ograniczony tylko do płuca, a wyższe liczby wskazują na większy rozmiar guza lub rozprzestrzenienie się poza płuca 57.

Nowoczesne technologie w diagnostyce raka płuca

W ostatnich latach nastąpił znaczący postęp w dziedzinie diagnostyki raka płuca. Nowoczesne technologie umożliwiają wczesne wykrywanie tego nowotworu oraz dokładniejsze określenie jego typu i zaawansowania, co przekłada się na bardziej skuteczne leczenie.

Robotyczna bronchoskopia

Robotyczna bronchoskopia to jedna z najnowszych technik stosowanych w diagnostyce raka płuca. W porównaniu z tradycyjną bronchoskopią, procedura ta zapewnia lekarzom większą precyzję i kontrolę 58. Robotyczna bronchoskopia umożliwia dotarcie do małych guzków położonych głęboko w płucach bez konieczności operacji, co stanowi przełom w uzyskiwaniu dokładnych wyników biopsji 59.

Biopsja płynna

Biopsja płynna to nieinwazyjna metoda diagnostyczna, która polega na badaniu próbki krwi w celu wykrycia DNA nowotworowego krążącego w krwiobiegu 60. Chociaż biopsja płynna nie może jeszcze zastąpić tradycyjnej biopsji tkanki w diagnostyce raka płuca, może ona dostarczyć cennych informacji na temat specyficznych mutacji genetycznych w komórkach nowotworowych, które mogą pomóc w doborze odpowiedniego leczenia 61.

Sztuczna inteligencja w diagnostyce raka płuca

Sztuczna inteligencja (AI) odgrywa coraz większą rolę w diagnostyce raka płuca. AI może pomóc w analizie obrazów z badań LDCT, zwiększając dokładność wykrywania guzków płucnych i zmniejszając liczbę wyników fałszywie dodatnich 62.

Badania wykazały, że gdy radiolodzy korzystali z systemów wspomagania komputerowego opartych na AI, ich zdolność do prawidłowej identyfikacji obrazów płuc bez istotnych zmian nowotworowych (tzw. swoistość) wzrosła o 57% w porównaniu do sytuacji, gdy nie korzystali z takiego systemu 63. Oznacza to, że na każdych 15-20 badanych pacjentów, jeden może uniknąć niepotrzebnych procedur, co zmniejsza lęk pacjenta i obciążenie systemu opieki zdrowotnej.

Zalecenia dla pacjentów

Osoby z grupy wysokiego ryzyka zachorowania na raka płuca powinny regularnie poddawać się badaniom przesiewowym za pomocą niskodawkowej tomografii komputerowej 64. Badania te mogą pomóc wykryć raka płuca we wczesnym stadium, kiedy jest on najłatwiejszy do leczenia.

Ważne jest jednak, aby pamiętać, że badania przesiewowe nie są dobrą alternatywą dla rzucenia palenia. Rzucenie palenia może znacząco zmniejszyć ryzyko zachorowania na raka płuca i zgonu z jego powodu 65.

Osoby, które doświadczają objawów mogących wskazywać na raka płuca, takich jak uporczywy kaszel, duszność, krwioplucie czy ból w klatce piersiowej, powinny niezwłocznie skontaktować się z lekarzem 6667.

Ważne jest, aby dokładnie omówić z lekarzem wszystkie kwestie związane ze stanem zdrowia podczas podejmowania decyzji o wykonaniu badań przesiewowych w kierunku raka płuca 68.

Podsumowanie

Wczesne wykrycie raka płuca ma kluczowe znaczenie dla zwiększenia szans na skuteczne leczenie i przeżycie. Badania przesiewowe za pomocą niskodawkowej tomografii komputerowej (LDCT) są zalecane dla osób z grupy wysokiego ryzyka, zwłaszcza dla obecnych i byłych palaczy 69.

Proces diagnostyczny raka płuca obejmuje badania obrazowe, biopsje oraz badania molekularne, które pomagają określić typ nowotworu i jego zaawansowanie. Nowoczesne technologie, takie jak robotyczna bronchoskopia, biopsja płynna oraz sztuczna inteligencja, przyczyniają się do poprawy jakości i dokładności diagnostyki.

Chociaż badania przesiewowe mogą pomóc w wykryciu raka płuca na wczesnym etapie, najlepszym sposobem na zmniejszenie ryzyka tego nowotworu jest rzucenie palenia. Osoby, które doświadczają objawów mogących wskazywać na raka płuca, powinny niezwłocznie skonsultować się z lekarzem.

Opieka nad pacjentami z rakiem płuca wymaga współpracy zespołu multidyscyplinarnego, w skład którego wchodzą pulmonolodzy, torakochirurdzy, onkolodzy, radiolodzy i patolodzy. Dzięki wspólnemu wysiłkowi tych specjalistów oraz wykorzystaniu najnowszych osiągnięć w dziedzinie diagnostyki, pacjenci z rakiem płuca mają coraz większe szanse na wczesne wykrycie choroby i skuteczne leczenie.

    Lung cancer is the second most common cancer in men and women in the United States; however, it remains the leading cause of cancer-related death in the United States and worldwide. […] Referral to a multidisciplinary lung cancer team, imaging, and confirmation through sputum cytology, thoracentesis, fine-needle aspiration, or mediastinoscopy are recommended. […] As of 2021, the U.S. Preventive Services Task Force recommends annual lung cancer screening using low-dose computed tomography starting at 50 years of age in patients with a 20 pack-year history. […] The initial evaluation for lung cancer begins with laboratory testing, including a complete blood count, serum chemistries, calcium levels, liver function tests, and chest radiography; CT of the chest with intravenous contrast media should be performed when there is a high level of suspicion, even if radiographic results are normal.

    Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early, it may be easier to treat. […] If a screening test result is abnormal, you may need to have more tests done to find out if you have cancer. These are called diagnostic tests. […] Three screening tests have been studied to see if they decrease the risk of dying from lung cancer. […] Screening with LDCT scans has been shown to decrease the risk of dying from lung cancer in heavy smokers. […] Screening with chest x-rays and/or sputum cytology does not decrease the risk of dying from lung cancer. […] Screening tests for lung cancer are being studied in clinical trials. […] Finding lung cancer may not improve health or help you live longer. […] False-negative test results can occur. […] False-positive test results can occur. […] Chest x-rays and CT scans expose the chest to radiation. […] Talk to your doctor about your risk for lung cancer and your need for screening tests.

[…] The only recommended screening test for lung cancer is low-dose computed tomography (also called a low-dose CT scan, or LDCT). […] Lung cancer screening has at least three risks: […] A lung cancer screening test can suggest that a person has lung cancer when no cancer is present. This is called a false-positive result. […] A lung cancer screening test can find cases of cancer that may never have caused a problem for the patient. This is called overdiagnosis. […] That is why lung cancer screening is recommended only for adults who are at high risk for developing the disease because of their smoking history and age, and who do not have a health problem that substantially limits their life expectancy or their ability or willingness to have lung surgery, if needed.

    Screening is the use of tests or exams to find a disease in people who dont have symptoms. […] Regular chest x-rays have been studied as a screening test for people at higher risk for lung cancer, but they havent been shown to help most people live longer, and therefore they arent recommended for lung cancer screening. […] At present, a test known as a low-dose CT (LDCT) scan is used to screen people at higher risk (mainly because they smoke or used to smoke) for lung cancer. LDCT scans can help find abnormal areas in the lungs that may be cancer. Research has shown that unlike chest x-rays, yearly LDCT scans to screen people at higher risk of lung cancer can save lives. For these people, getting yearly LDCT scans before symptoms start helps lower the risk of dying from lung cancer. […] Lung cancer screening is recommended for certain people who smoke or used to smoke, but who don’t have any signs or symptoms.

    In 2011, results from the US-based National Lung Screening Trial (NLST) indicated a 20% decrease in lung cancer-related mortality after a median follow-up of 6.5 years in patients undergoing annual LDCT screening compared with scanning by radiography at the same frequency for 3 years. […] This evidence suggests that people with a history of smoking benefit from screening. Hence, chest LDCT has been recommended as the standard screening approach for lung cancer in asymptomatic populations with high risk, in accordance with the National Comprehensive Cancer Network (NCCN), American Cancer Society (ACS), and US Preventive Services Task Force (USPSTF). […] In addition, analysis of lung cancer incidence and mortality through the US Surveillance, Epidemiology, and End Results (SEER) and the Global Burden of Disease (GBD) database in recent years has indicated that the proportion of stage I in lung cancer in the US significantly increased after the broad clinical introduction of LDCT screening in 2002, when the NLST trial started. […] In 2011, after LDCT was approved for lung cancer screening, the lung cancer-related mortality for stages I to III has undergone an average annual decline exceeding 10%, thereby indicating the value of CT screening in increasing overall lung cancer survival at the population level.

    https://www.mountsinai.org/care/cancer/services/lung/what-is/screening-diagnosis
    Lung cancer screening is extremely important since lung cancer might not have symptoms in its early stages. Screening can help us find any abnormalities that suggest early lung cancer. The earlier the stage of disease the treatment starts, the better the chance of a cure. Research shows the most effective lung cancer screening uses low-dose computed tomography (CT) scans. This approach can also help doctors find other conditions such as heart disease. Studies have demonstrated that lung cancer screening with low-dose CT can reduce the mortality of lung cancer by 20-25 percent when done in defined high-risk populations (over the age of 50 years and a tobacco history of at least 20 pack-years). […] Physicians with our Lung Cancer Screening Program use imaging tests to help diagnose and track lung cancer. They create pictures of the inside of your body. The most common types of imaging tests we use are: […] If we find any abnormalities, your doctor will order further diagnostic tests, such as fine-needle aspiration, bronchoscopy, endobronchial ultrasound, and molecular testing.
  • #9 Advances in lung cancer screening and early detection
    https://pmc.ncbi.nlm.nih.gov/articles/PMC9196057/
    The 5-year survival rate for early-stage lung cancer is greater than that for advanced-stage lung cancer. Patients with stage IA lung cancer have a high 5-year survival rate exceeding 75%. […] Given the frequent absence of symptoms before locally advanced or metastatic deposit, and the aggressive and heterogeneous biological characteristics of the disease, clinical intervention is more effective in earlier stages of lung cancer. […] Therefore, early screening and diagnosis are the most effective approaches for improving long-term survival and are being actively explored. […] LDCT is a computed tomography technique that uses X-rays to create internal body images. […] LDCT has been demonstrated to be the only efficient and promising approach for lung cancer screening, on the basis of 2 independent, sufficiently powered RCTs.

    Lung cancer screening is a tool healthcare providers use to detect lung cancer early, when its more easily treated. They take images of your lungs once a year with a low-dose CT scan. Lung cancer screening is recommended for people between the ages of 50 and 80 who smoke or who quit less than 15 years ago. […] Lung cancer screening is a yearly low-dose CT scan (LDCT) that can show potentially cancerous tumors when theyre still small. LDCT scans take pictures of the insides of your lungs. Screening means that you have a regular test or imaging to catch a disease before it starts causing symptoms. […] You should start getting screened at age 50 if you currently smoke or quit within the past 15 years. While anyone can get lung cancer, people who smoke or used to smoke are at a higher risk.

    We focus on finding lung cancer at its earliest stages. Our pulmonary and thoracic physicians use the latest imaging techniques to detect lung abnormalities in patients who are at risk for developing lung cancer. This thorough screening for lung cancer process enables us to deliver a diagnosis as early as possible so treatments will be more effective. […] If youve ever been a smoker or you have other lung cancer risk factors, regular screening is the best way to detect disease. Lung cancer symptoms often dont appear until the cancer is advanced. A screening for lung cancer can detect long before you realize its there, and finding lung cancer early allows your care team to deliver timely lifesaving treatments. […] Low-dose CT (LDCT) screening combines an X-ray machine and sophisticated computers to create detailed images of your chest. LDCT is very sensitive and precise. This technology detects even the smallest nodule on the lungs while using 90% less radiation than a traditional chest imaging scan. During a LDCT scan, youll lie on your back on an exam table. You may be asked to raise your hands over your head. The table will slowly move through the machine while you hold your breath for each short scan (10 seconds or less). Screening is painless and usually takes just a few minutes.

    LDCT lung screening is recommended for people who are at high risk for lung cancer. Screening before signs of lung cancer appear may lower the risk of death by as much as 20%. […] Studies show that when compared to single-view chest X-ray screening, LDCT lung screening can lower the risk of death from lung cancer by 20% in people who are at risk. […] Low-dose CT is one of the easiest screening exams you can have. The exam takes less than 10 minutes. […] About 1 out of 4 LDCT lung screenings will find something in the lungs that may require additional imaging or evaluation. Most of the time these findings are lung nodules. Lung nodules are very small collections of tissue in the lungs. These nodules are very common, and the vast majority of them more than 97% are not cancer. Most are normal lymph nodes or small areas of scarring from past infections.

    Lung cancer biomarker testing sometimes referred to as tumor, molecular, or genomic testing looks for changes in the tumor’s DNA. […] Biomarker testing looks for mutations, additions, deletions, or rearrangements in DNA. […] Knowing this information can help influence treatment options. […] Not all lung cancers are the same. When scientists look at tissue from a person’s lung cancer tumor under a microscope they can tell what type (non-small cell, small cell or carcinoid) and subtype the lung cancer is. […] It involves testing tumor tissue for abnormalities in its DNA and levels of specific proteins in the tumor. […] If doctors know exactly what causes the tumor to grow, a patient may be able to go on a „targeted” therapy that can slow tumor growth or shrink the tumor. […] Testing can also show levels of an important protein called PD-L1 which may help predict if a patient would benefit from immunotherapy.

    At Google we have previously developed machine learning (ML) models for lung cancer detection, and have evaluated their ability to automatically detect and classify regions that show signs of potential cancer. Performance has been shown to be comparable to that of specialists in detecting possible cancer. […] We evaluate the systems utility in improving clinician performance through randomized reader studies in both the US and Japan, using the local cancer scoring systems (Lung-RADSs V1.1 and Sendai Score) and image viewers that mimic realistic settings. We found that reader specificity increases with model assistance in both reader studies. […] Our study results demonstrated that when radiologists used the system in their clinical evaluation, they had an increased ability to correctly identify lung images without actionable lung cancer findings (i.e., specificity) by an absolute 57% compared to when they didn’t use the assistive system. This potentially means that for every 15-20 patients screened, one may be able to avoid unnecessary follow-up procedures, thus reducing their anxiety and the burden on the health care system.
