# Clinical Challenges and Management Strategies in Pulmonary Large-Cell Neuroendocrine Carcinoma

## TL;DR

This paper discusses the challenges in diagnosing and treating a rare aggressive lung cancer called LCNEC, using a case study to emphasize the importance of early detection and multidisciplinary care.

## Contribution

The paper contributes a detailed case report of LCNEC management and emphasizes the need for early detection and collaborative treatment strategies.

## Key findings

- LCNEC is often diagnosed at an advanced stage due to nonspecific symptoms.
- A multidisciplinary approach is crucial for optimal management of LCNEC.
- Surgical complications may require additional interventions like bronchial stenting.

## Abstract

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare but aggressive malignancy of the lung. Its nonspecific presentation and propensity for severe disease at the time of diagnosis create challenges in treatment. We report a case of an asymptomatic 61-year-old female who was incidentally found to have a pulmonary nodule after a fall. Upon further workup, she was found to have an aggressive LCNEC. The patient underwent a robotic-assisted left upper lobectomy, which was complicated by left lower lobe bronchus kinking and post-obstructive atelectasis, warranting further management by thoracic surgery. The patient additionally underwent video-assisted thoracoscopic surgery (VATS), open thoracotomy, pneumopexy, and bronchial stenting. This case highlights the need for strategies for early detection in at-risk populations. A multidisciplinary approach, which may involve both medical and surgical subspecialties, is essential in the management of this complex disease from the time of diagnosis to follow-up postoperatively to achieve the best clinical outcome.
