Tension hydrothorax in a patient with a history of pulmonary tuberculosis.

A tension hydrothorax is a massive pleural effusion that leads to hemodynamic instability. Here we present a case of tension hydrothorax secondary to poorly differentiated carcinoma. A 74-year-old male smoker presented after a one-week history of dyspnea and unintentional weight loss. Physical exam demonstrated tachycardia, tachypnea, and decreased breath sounds diffusely over the right lung. Imaging revealed a massive pleural effusion causing mass effect on the mediastinum with tension physiology. Chest tube placement revealed an exudative effusion with negative cultures and cytology. Pleural biopsy revealed atypical epithelioid cells consistent with poorly differentiated carcinoma.

Malpositioned nephrostomy tube with associated hemorrhagic pleural effusion.

Pleural effusion of extra-vascular origin has a large differential diagnosis. Ultrasonography can be utilized alongside pleural fluid analysis to determine a pleural effusion's complexity and size, thus helping aid in both diagnostic and therapeutic management. We describe the case of a 38-year-old male with a prior medical history of neurogenic bladder and nephrolithiasis with percutaneous nephrostomy tube placed one week prior to presentation. Using ultrasonography, the nephrostomy tube was determined to be positioned within the pleural cavity with a resultant hemorrhagic pleural effusion.

Does definitive local therapy have a role in select HER2+ de novo metastatic breast cancer patients treated with dual anti-HER2 blockade?

PURPOSE: The role of surgery with curative intent in HER2+ de novo metastatic breast cancer (dnMBC) is uncertain in the era of dual antibody therapy. We sought to determine from existing retrospective data current practice patterns and if an association exists between surgery to the primary tumor and improved survival in HER2+ dnMBC patients treated with dual anti-HER2 blockade, accounting for selection bias. METHODS: This study employed data from the National Cancer Database (NCDB) from the years 2013 to 2015. Study inclusion was limited to adult women with HER2+ dnMBC, who received immunotherapy/biologic response modifier drugs (BRM) as a first line treatment. Patients who received both systemic therapy and surgery to the primary breast tumor and patients who received systemic therapy alone were analyzed in two groups. Chi-square test for discrete variables and Wilcox on Rank-Sum test for numeric variables was used to compare the two groups based on patient, tumor, and treatment characteristics. The primary endpoint was overall survival from the time of diagnosis to the time of death. RESULTS: 928 women with HER2+ dnMBC treated with BRM were identified with 43.5% (n = 404) receiving surgery and 56.5% (n = 524) receiving systemic therapy alone. The 3-year overall survival was superior for the surgery group (74.1%, 95% CI 67.9-79.2%) compared to the no surgery group (53.3%; 95% CI 47.6-58.6%). The no surgery group had median overall survival of 39.8 months (95% CI 34.1-44.9), while the surgery group had not yet reached median overall survival. CONCLUSION: In a group of HER2+ dnMBC patients receiving systemic treatment in the era of dual antibody therapy, patients who underwent surgery had a superior 3-year survival rate than those who did not. There may be a role for a prospective trial in HER2+ dnMBC patients with an excellent response to dual HER2 blockade to investigate the contribution of curative intent local therapy to the primary tumor compared to systemic therapy alone.
