Multimodality Treatment including Surgery Related to the Type of N2 Involvement in Locally Advanced Non-Small Cell Lung Cancer.

For patients with locally advanced non-small cell lung cancer (NSCLC) or positive N1 nodes, multimodality treatment is indicated. However, the optimal management of patients presenting with ipsilateral positive mediastinal nodes (N2 disease) has not been determined yet. Different treatment regimens consisting of chemotherapy, radiation therapy, and surgery have been proposed and implemented previously. In more recent years, immunotherapy and targeted therapies have been added as therapeutic options. The role of surgery is currently redefined. Recent studies have shown that surgical resection after induction immunotherapy or targeted therapy is feasible and yields good short-term results. In this review, we summarize the latest data on multimodality treatment options for stage IIIA-N2 locally advanced NSCLC, depending on the extent of nodal involvement.

Surgery after Induction Targeted Therapy and Immunotherapy for Lung Cancer.

Multimodality therapy for locally advanced non-small cell lung cancer (NSCLC) is a complex and controversial issue, especially regarding optimal treatment regimens for patients with ipsilateral positive mediastinal nodes (N2 disease). Many trials investigating neoadjuvant immunotherapy and targeted therapy in this subpopulation have shown promising results, although concerns have risen regarding surgical feasibility. A thorough literature review was performed, analyzing all recent studies regarding surgical morbidity and mortality. Despite the fact that two major trials investigating this subject were terminated early, the overall consensus is that surgical management seems feasible. However, dissection of hilar vessels may be challenging due to hilar fibrosis. Further research is necessary to identify the role of surgery in these multimodality treatment regimens, and to define matters such as the optimal treatment regimen, the dosage of the different agents used, the interval between induction therapy and surgery, and the role of adjuvant therapy.

Intracranial complications of midline nasal dermoid cysts.

BACKGROUND: Nasal dermoid cysts are common tumors in children. Due to anomalies in embryologic development of the nasal complex, sometimes an intracranial extension exists. When these cysts become infected they can lead to meningitis, brain abscess and death. METHODS: We report the case of a 1.5-year-old girl admitted to the paediatric intensive care unit after infection of a nasal dermoid cyst. RESULTS: The infant had a spiking fever and epileptic seizures. She was stabilized, intubated and a CT scan showed a subcutaneous mass with an adjacent zone of encephalitis and brain abscess formation. Neurosurgical interventions were necessary to lower intracranial pressure and control infectious spread. After a hospital stay of 69 days the child could be discharged. Due to her young age, irreversible brain damage is expected. CONCLUSION: Nasal midline dermoid cysts are considered benign swellings. When an intracranial extension exists, infection can lead to deleterious complications. It is important for health care practitioners to be aware of this imminent risk. Suspicion of a nasal midline dermoid cyst should prompt a careful clinical work-up with an ultrasound followed by CT or MRI imaging. The treatment is complete excision to avoid disastrous complications and recurrences.
