The National Cancer Institute’s SEER database, which stands for Surveillance, Epidemiology and End Results, reports that the 5-year relative combined survival rate for NSCLC is 23 percent. meaning for all comers diagnosed with NSCLC, 23 percent can expect to measure five years or more. However, within that estimate lies tons of nuance and variability. for instance , cases of carcinoma caught early, before the cancer has spread beyond its point of origin, have a 5-year relative survival rate of 60 percent. For cancers that have spread to other locations within the same region, meaning within the lung, or chest, the 5-year relative survival rate is 33 percent. For people that have distant metastases – meaning cancers that have spread to organs outside the chest, like the brain or liver – the 5-year relative survival rate is 6 percent.
For SCLC, the numbers are a touch more grim. Twenty-nine percent of individuals diagnosed with localized SCLC can expect to measure five years or more. The regional 5-year survival rate is 15 percent and for patients diagnosed within the distant stage, the 5-year relative survival rate is 3 percent. Combining all SEER stage estimates for SCLC leads to an overall rate of 6 percent.
Survival rates are often useful for predicting how long someone with a specific type or stage of carcinoma might expect to measure , but however , they don’t paint the entire picture, and every case of cancer is different. many of us with advanced NSCLC or SCLC live for years despite having metastatic disease. Other factors which will impact your prognosis and survival timeline include the standard of care you receive, your age, genetic factors and other comorbidities, or disease you’ll already be handling .
Generally speaking, the healthier you’re overall, the higher your outlook, but even for the direst cases, new treatment breakthroughs are extending anticipation significantly. This area of drugs is evolving rapidly and what could be true today could change tomorrow. because the ACS notes, people now being diagnosed with either NSCLC or SCLC “may have a far better outlook than these numbers show. Treatments improve over time, and these numbers are supported people that were diagnosed and treated a minimum of five years earlier.”
