From the Guidelines
The prognosis for lung cancer with distal node metastasis is generally poor, with a 5-year survival rate typically below 10%. This represents stage IV disease, indicating the cancer has spread beyond the lungs to distant lymph nodes or organs. According to the most recent study 1, the 5-year survival rate varies significantly depending on the stage at diagnosis, ranging from 57% for localized-stage disease to 5% for patients with metastatic disease.
Treatment Options
Treatment usually focuses on systemic therapy rather than curative approaches. First-line treatment often includes platinum-based chemotherapy combinations (such as carboplatin/paclitaxel or cisplatin/pemetrexed), with dosing based on body surface area and typically administered every 3 weeks for 4-6 cycles. For patients with specific genetic mutations, targeted therapies may be used: EGFR mutations may be treated with osimertinib (80mg daily), ALK rearrangements with alectinib (600mg twice daily), or ROS1 rearrangements with entrectinib (600mg daily). Immunotherapy with checkpoint inhibitors like pembrolizumab (200mg every 3 weeks) may be appropriate for patients with high PD-L1 expression, as suggested by studies such as 1 and 1.
Monitoring and Palliative Care
Despite these treatments, median survival typically ranges from 12-24 months, though some patients with targetable mutations may survive longer. Regular imaging every 2-3 months is essential to monitor treatment response, and palliative care should be integrated early to manage symptoms and improve quality of life. The importance of early diagnosis and treatment is highlighted in studies such as 1 and 1, which emphasize the need for a multidisciplinary approach to managing lung cancer.

- Regular imaging and palliative care are essential to monitor treatment response and improve quality of life.
From the Research
Prognosis for Lung Cancer with Distal Node Metastasis
- The prognosis for lung cancer with distal node metastasis is generally poor, but it can vary depending on the stage and type of cancer, as well as the treatment approach 2, 3, 4, 5, 6.
- Studies have shown that concurrent chemoradiotherapy with cisplatin and pemetrexed can be an effective treatment for locally advanced non-small cell lung cancer, with median overall survival rates ranging from 18.7 to 34 months 3, 4, 5.
- The addition of consolidation chemotherapy after concurrent chemoradiotherapy may also improve survival outcomes, with one study showing a median overall survival of 30.3 months 4.
- However, the optimal treatment regimen for lung cancer with distal node metastasis is still unclear, and more research is needed to determine the best approach 2, 5, 6.
- Factors such as tumor histology, performance status, and pulmonary function may also impact prognosis and treatment outcomes 3, 4, 5.
Treatment-Related Toxicities
- Concurrent chemoradiotherapy with cisplatin and pemetrexed can be associated with significant toxicities, including esophagitis, pneumonitis, and hematologic adverse events 3, 4, 5.
- The incidence of grade 3-4 toxicities can be high, with one study reporting a rate of 39% for neutropenia and 14% for febrile neutropenia 3.
- However, the toxicity profile of pemetrexed and cisplatin can be manageable with appropriate supportive care and dose modifications 4, 5.
Ongoing Research
- Several ongoing clinical trials are investigating the efficacy and safety of pemetrexed-based regimens in locally advanced non-small cell lung cancer, including the phase III PROCLAIM trial 5, 6.
- These studies may provide further insight into the optimal treatment approach for lung cancer with distal node metastasis and help to improve survival outcomes for patients with this disease 2, 3, 4, 5, 6.
