Lung Cancer Screening Dramatically Increases Long-term Survival Rate

Published

 on

November 22, 2022 — Diagnosing early-stage lung cancer with low-dose CT screening drastically improves the long-term survival rate of cancer patients, according to a large-scale, 20-year international study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

“While screening doesn’t prevent cancers from occurring, it is an important tool in identifying lung cancers in their early stage when they can be surgically removed,” said the study’s lead author, Claudia Henschke, Ph.D., M.D., professor of radiology and director of the Early Lung and Cardiac Action Program at the Icahn School of Medicine at Mount Sinai in New York.

Lung cancer is the leading cause of cancer death. According to the American Lung Association, the average lung cancer five-year survival rate is 18.6 percent. Only 16 percent of lung cancers are diagnosed at an early stage, and more than half of people with lung cancer die within one year of being diagnosed.

While treatments of more advanced-stage cancers with targeted therapy and immunotherapy have come a long way, the best tool in the fight against cancer deaths is early diagnosis through low-dose CT screening before symptoms appear.

“Symptoms occur mainly in late-stage lung cancer,” Dr. Henschke said. “Thus, the best way to find early-stage lung cancer is by enrolling in an annual screening program.”

Dr. Henschke and colleagues have been studying the effectiveness of cancer detection with low-dose CT screening for years. The efforts of the researchers to advance CT screening for early lung disease led to the creation of the International Early Lung Cancer Action Program (I-ELCAP). Started in 1992, this multi-institution, multi-national research program has enrolled over 87,000 participants from over 80 institutions.

In 2006, the researchers identified a 10-year survival rate of 80% for the patients whose cancer was identified by CT screening. For this study, they looked at 20-year survival rates.

“What we present here is the 20-year follow-up on participants in our screening program that were diagnosed with lung cancer and subsequently treated,” Dr. Henschke said. “The key finding is that even after this long a time interval they are not dying of their lung cancer.”

The study found that the 20-year survival rate was 80% for the 1,285 I-ELCAP participants who were diagnosed with early-stage lung cancer. The survival rate for both the 139 participants with nonsolid cancerous lung nodules and the 155 participants with nodules of part-solid consistency was 100%. For the 991 participants with solid nodules, the survival rate was 73%.

The researchers also estimated survival for clinical Stage IA lung cancers and for resected pathologic stage IA lung cancers measuring 10mm or less in average diameter of length and width on the same CT image. A stage I lung cancer is a very small tumor that has not spread to any lymph nodes.

Lung cancer survival for clinical Stage IA participants was 86%, regardless of consistency. For participants with pathologic Stage IA cancers of 10 mm or less, the 20-year survival rate was 92%.

The results show that after 20 years, patients diagnosed with lung cancer at an early stage via CT screening have significantly better outcomes. By surgically removing the cancer when it is small enough, patients can be effectively cured in the long term.

The findings demonstrate the importance of routine and early screening.

“Ultimately, anyone interested in being screened needs to know that if they are unfortunate enough to develop lung cancer, that it can be cured if found early,” Dr. Henschke said.

The U.S. Preventive Services Task Force recommends annual lung cancer screening with low-dose CT in adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years.

Cancer Awareness Month

Posted on: Apr 18, 2024

April is Cancer Awareness Month

As we recognize Cancer Awareness Month, we stand together to raise awareness, support those affected, advocate for prevention, early detection, and continued research towards a cure. Cancer is the leading cause of death for Métis women and the second leading cause of death for Métis men. The Otipemisiwak Métis Government of the Métis Nation Within Alberta is working hard to ensure that available supports for Métis Citizens battling cancer are culturally appropriate, comprehensive, and accessible by Métis Albertans at all stages of their cancer journey.

300x250x1

Receiving a cancer diagnosis, whether for yourself or a loved one, can feel overwhelming, leaving you unsure of where to turn for support. In June, our government will be launching the Cancer Supports and Navigation Program which will further support Métis Albertans and their families experiencing cancer by connecting them to OMG-specific cancer resources, external resources, and providing navigation support through the health care system. This program will also include Métis-specific peer support groups for those affected by cancer.

With funding from the Canadian Partnership Against Cancer (CPAC) we have also developed the Métis Cancer Care Course to ensure that Métis Albertans have access to culturally safe and appropriate cancer services. This course is available to cancer care professionals across the country and provides an overview of who Métis people are, our culture, our approaches to health and wellbeing, our experiences with cancer care, and our cancer journey.

Together, we can make a difference in the fight against cancer and ensure equitable access to culturally safe and appropriate care for all Métis Albertans. Please click on the links below to learn more about the supports available for Métis Albertans, including our Compassionate Care: Cancer Transportation program.

I wish you all good health and happiness!

Type 2 diabetes is not one-size-fits-all: Subtypes affect complications and treatment options – The Conversation

Published

 on


You may have heard of Ozempic, the “miracle drug” for weight loss, but did you know that it was actually designed as a new treatment to manage diabetes? In Canada, diabetes affects approximately 10 per cent of the general population. Of those cases, 90 per cent have Type 2 diabetes.

This metabolic disorder is characterized by persistent high blood sugar levels, which can be accompanied by secondary health challenges, including a higher risk of stroke and kidney disease.

Locks and keys

In Type 2 diabetes, the body struggles to maintain blood sugar levels in an acceptable range. Every cell in the body needs sugar as an energy source, but too much sugar can be toxic to cells. This equilibrium needs to be tightly controlled and is regulated by a lock and key system.

300x250x1

In the body’s attempt to manage blood sugar levels and ensure that cells receive the right amount of energy, the pancreatic hormone, insulin, functions like a key. Cells cover themselves with locks that respond perfectly to insulin keys to facilitate the entry of sugar into cells.

Unfortunately, this lock and key system doesn’t always perform as expected. The body can encounter difficulties producing an adequate number of insulin keys, and/or the locks can become stubborn and unresponsive to insulin.

All forms of diabetes share the challenge of high blood sugar levels; however, diabetes is not a singular condition; it exists as a spectrum. Although diabetes is broadly categorized into two main types, Type 1 and Type 2, each presents a diversity of subtypes, especially Type 2 diabetes.

These subtypes carry their own characteristics and risks, and do not respond uniformly to the same treatments.

To better serve people living with Type 2 diabetes, and to move away from a “one size fits all” approach, it is beneficial to understand which subtype of Type 2 diabetes a person lives with. When someone needs a blood transfusion, the medical team needs to know the patient’s blood type. It should be the same for diabetes so a tailored and effective game plan can be implemented.

This article explores four unique subtypes of Type 2 diabetes, shedding light on their causes, complications and some of their specific treatment avenues.

Severe insulin-deficient diabetes: We’re missing keys!

In severe insulin-deficient diabetes, beta cells limit production of the keys that unlock cells to allow entry of sugar from the blood.

Insulin is produced by beta cells, which are found in the pancreas. In the severe insulin-deficient diabetes (SIDD) subtype, the key factories — the beta cells — are on strike. Ultimately, there are fewer keys in the body to unlock the cells and allow entry of sugar from the blood.

SIDD primarily affects younger, leaner individuals, and unfortunately, increases the risk of eye disease and blindness, among other complications. Why the beta cells go on strike remains largely unknown, but since there is an insulin deficiency, treatment often involves insulin injections.

Severe insulin-resistant diabetes: But it’s always locked!

In severe insulin-resistant diabetes, the locks start ignoring the keys, triggering the beta cells to produce even more keys to compensate.

In the severe insulin-resistant diabetes (SIRD) subtype, the locks are overstimulated and start ignoring the keys. As a result, the beta cells produce even more keys to compensate. This can be measured as high levels of insulin in the blood, also known as hyperinsulinemia.

This resistance to insulin is particularly prominent in individuals with higher body weight. Patients with SIRD have an increased risk of complications such as fatty liver disease. There are many treatment avenues for these patients but no consensus about the optimal approach; patients often require high doses of insulin.

Mild obesity-related diabetes: The locks are sticky!

Mild obesity-related (MOD) diabetes represents a nuanced aspect of Type 2 diabetes, often observed in individuals with higher body weight. Unlike more severe subtypes, MOD is characterized by a more measured response to insulin. The locks are “sticky,” so it is challenging for the key to click in place and open the lock. While MOD is connected to body weight, the comparatively less severe nature of MOD distinguishes it from other diabetes subtypes.

To minimize complications, treatment should include maintaining a healthy diet, managing body weight, and incorporating as much aerobic exercise as possible. This is where drugs like Ozempic can be prescribed to control the evolution of the disease, in part by managing body weight.

Mild age-related diabetes: I’m tired of controlling blood sugar!

In people with mild age-related diabetes, both the locks and the beta cells that produce keys are tired, resulting in fewer keys and stubborn locks.
(Lili Grieco-St-Pierre, Jennifer Bruin/Created with BioRender.com)

Mild age-related diabetes (MARD) happens more often in older people and typically starts later in life. With time, the key factory is not as productive, and the locks become stubborn. People with MARD find it tricky to manage their blood sugar, but it usually doesn’t lead to severe complications.

Among the different subtypes of diabetes, MARD is the most common.

Unique locks, varied keys

While efforts have been made to classify diabetes subtypes, new subtypes are still being identified, making proper clinical assessment and treatment plans challenging.

In Canada, unique cases of Type 2 diabetes were identified in Indigenous children from Northern Manitoba and Northwestern Ontario by Dr. Heather Dean and colleagues in the 1980s and 90s. Despite initial skepticism from the scientific community, which typically associated Type 2 diabetes with adults rather than children, clinical teams persisted in identifying this as a distinct subtype of Type 2 diabetes, called childhood-onset Type 2 diabetes.

Indigenous community research partnerships can help address health inequities


Childhood-onset Type 2 diabetes is on the rise across Canada, but disproportionately affects Indigenous youth. It is undoubtedly linked to the intergenerational trauma associated with colonization in these communities. While many factors are likely involved, recent studies have discovered that exposure of a fetus to Type 2 diabetes during pregnancy increases the risk that the baby will develop diabetes later in life.

Acknowledging this distinct subtype of Type 2 diabetes in First Nations communities has led to the implementation of a community-based health action plan aimed at addressing the unique challenges faced by Indigenous Peoples. It is hoped that partnered research between communities and researchers will continue to help us understand childhood-onset Type 2 diabetes and how to effectively prevent and treat it.

A mosaic of conditions

Type 2 diabetes is not uniform; it’s a mosaic of conditions, each with its own characteristics. Since diabetes presents so uniquely in every patient, even categorizing into subtypes does not guarantee how the disease will evolve. However, understanding these subtypes is a good starting point to help doctors create personalized plans for people living with the condition.

While Indigenous communities, lower-income households and individuals living with obesity already face a higher risk of developing Type 2 diabetes than the general population, tailored solutions may offer hope for better management. This emphasizes the urgent need for more precise assessments of diabetes subtypes to help customize therapeutic strategies and management strategies. This will improve care for all patients, including those from vulnerable and understudied populations.
