Lung Cancer (Non-Small Cell): Prognosis, Treatment Options, and Further Info

Advanced Non-Small Cell Lung Cancer (NSCLC) is a common type of lung cancer, often diagnosed at a later stage. This article will explore the main subtypes of advanced NSCLC, their characteristics, and the treatment options available.

Subtypes and Characteristics

There are four main subtypes of advanced NSCLC: adenocarcinoma, squamous cell carcinoma, large cell carcinoma (including large cell neuroendocrine carcinoma - LCNEC), and oligometastatic NSCLC. Each subtype has specific features and treatment approaches.

Adenocarcinoma is the most common NSCLC subtype, further subdivided by degree of tumor invasion. This subtype often occurs in nonsmokers and is frequently associated with genetic mutations such as EGFR and ALK rearrangements.
Squamous Cell Carcinoma originates in the squamous cells lining the airways and is strongly linked to smoking. It is typically less likely to have targetable mutations but may have high PD-L1 expression.
Large Cell Carcinoma and Large Cell Neuroendocrine Carcinoma (LCNEC) are less common and characterized by large, undifferentiated cells. LCNEC behaves aggressively, similar to small-cell lung cancer (SCLC), despite being classified under NSCLC.
Oligometastatic NSCLC (OMD-NSCLC) is a clinically distinct advanced-stage subtype characterized by limited number and sites of metastases. It has a more indolent course compared to broadly metastatic disease.

Treatment Options

Treatment plans for advanced NSCLC are personalized for each individual, considering their overall health, where the cancer has spread, and symptoms they are experiencing.

Targeted Therapy is used for adenocarcinoma with specific mutations (e.g., EGFR, ALK). Targeted agents like osimertinib (EGFR inhibitor) and combinations such as amivantamab/lazertinib have become standard.
Chemotherapy is often used in combination or as second-line treatment, especially when tumors lack specific mutations. Regimens vary depending on histologic subtype and patient factors.
Immunotherapy is increasingly integrated into treatment paradigms, particularly in patients with high PD-L1 expression or no actionable mutations. Immune checkpoint inhibitors targeting PD-1/PD-L1 proteins are used either alone or in combination with chemotherapy.
Local Ablative Therapy (LAT) is particularly relevant in oligometastatic NSCLC. LAT such as surgery or radiotherapy can be combined with systemic therapies to improve outcomes by eradicating localized disease.

Organizations like the American Lung Association and ACS can provide emotional and financial help, as well as directing people to support networks. If a person's airways are blocked, doctors may recommend laser therapy or internal radiation therapy.

It's important to remember that while advanced NSCLC is difficult to cure, treatments aim to improve a person's quality of life and may help them live longer. The 5-year survival rate for people with advanced NSCLC is approximately 9%.
