ABSTRACT
OBJECTIVES: Lobectomy may unnecessarily resect healthy lung parenchyma in Stage 1A non-small cell lung cancers (NSCLC). Segmentectomies may provide a lung-sparing option. VATS segmentectomies can be technically challenging; robotics may have features that provide advantages in performing segmentectomies. We describe the association of the robot on national trends in segmentectomies. METHODS: The National Cancer Database (2010-2017) was queried for patients with Stage 1A NSCLC who underwent lobectomies and segmentectomies. The proportion of segmentectomies vs. lobectomies and the proportion of robotic vs. VATS segmentectomies was calculated annually. RESULTS: The proportion of segmentectomies increased compared to lobectomies for all surgical approaches but remained constant for minimally-invasive approaches. The proportion of robotic segmentectomies increased over the years compared to VATS segmentectomies. Descriptive statistics are reported as numbers and proportions. Trends in the proportions of lobectomies and segmentectomies were compared using Chi-squared test for categorical variables and unpaired t-test for independent means. A p-value of <0.05 was considered statistically significant. Statistical analysis was performed using SPSS Statistics Software version 24 (IBM Corp, Armonk, NY). CONCLUSIONS: We demonstrate an increasing trend and proportion of robotic segmentectomies being performed in comparison to VATS segmentectomies. The robotic platform may facilitate the performance of more segmentectomies for early-stage NSCLC.

Sialadenoma papilliferum is a tumor of salivary gland origin. It is believed that sialadenoma papilliferum is a benign lesion usually known to occur in the hard palate, retromolar fat pads, lips, and parotid glands. Its origin in the bronchial tree is an extremely rare occurrence. We report only the fourth known case of bronchial sialadenoma papilliferum and the first to originate in the trachea. The patient underwent successful resection of the lesion, with complete relief of his dyspnea.

Pleural involvement in lymphoma is rare as the initial presentation of disease in the immunocompetent patient. We describe a rare case of primary, isolated pleural B-cell lymphoma in a 75-year-old female, previously treated for adenocarcinoma of the left lung with lobectomy and chemotherapy, who presented with shortness of breath. A CT scan of the chest revealed a right-sided pleural effusion and pleural thickening. She underwent multiple nondiagnostic thoracenteses. A subsequent surgical biopsy was diagnostic of large B-cell lymphoma.
