Pulmonary metastasectomy in uterine malignancies: outcome and prognostic factors

Lung Metastases: Current Surgical Indications and New Perspectives

Pulmonary metastasectomy is an established treatment that can provide improved long- term survival for patients with metastatic tumor(s) in the lung. In this mini-review, we discuss the state of the art of thoracic surgery in surgical management of lung metastases which actually occurs for a large part of surgical activity in thoracic surgery department. We describe the principles of surgical therapy that have been defined across the time, and that should remain the milestones of lung metastases treatment: a radical surgery and an adequate lymphadenectomy. We then focus on current surgical indications and report the oncological results according to the surgical approach (open vs. mini-invasive), the histological type and number of lung metastases, and in case of re-metastasectomy. Finally, we conclude with a brief overview about the future perspectives in thoracic surgery in treatment of lung metastases.

The accuracy of cone-beam computed tomography and augmented fluoroscopy-guided bronchoscopic marking of multiple small-sized pulmonary nodules in a hybrid operating room: a retrospective cohort study

Background

For the minimally invasive excision of small-sized pulmonary nodules, bronchoscopic markings are increasingly being performed owing to advancements in video-assisted thoracic surgery (VATS). Hybrid operating room equipment is utilized for bronchoscopic VATS markings. We aimed to compare the marking accuracy between bronchoscopic VATS and other marking techniques such as computed tomography-guided percutaneous marking and conventional X-ray fluoroscopy-guided bronchoscopic marking.

Methods

Patients with small-sized pulmonary nodules scheduled to undergo VATS were enrolled in the study. A mixture of 50 to 100 µL of diluted indocyanine green and iopamidol was injected adjacent to the pulmonary nodules as a VATS marker. Patients receiving each of the three image-guided techniques were categorized into group A (computed tomography-guided percutaneous injection), group B (X-ray fluoroscopy-guided virtual bronchoscopy-assisted bronchoscope injection), and group C (cone-beam computed tomography and augmented fluoroscopy-guided virtual bronchoscope-assisted bronchoscopic injection in the hybrid operating room). VATS marking accuracy and procedural complications were compared among the three groups.

Results

In total, 61 patients with 73 pulmonary nodules were eligible for analysis. VATS marking was successful for 15/16 nodules in group A, 28/30 nodules in group B, and 25/27 nodules in group C. Marking accuracy was 5.75±4.59, 15.00±14.02, and 6.05±6.11 (mm), respectively. Multiple markings were successful in 0/1 (0%), 5/6 (83.3%), and 5/5 (100.0%) nodules in groups A, B, and C, respectively. A small pneumothorax occurred in 3/15 (20.0%) patients in group A.

Conclusions

The cone-beam computed tomography and augmented fluoroscopy-guided bronchoscopic approach performed in a hybrid operating room is accurate and equivalent to the computed tomography-guided percutaneous approach, and it enables the VATS marking of multiple pulmonary nodules without causing a secondary pneumothorax.

Pulmonary metastasis with coexisting pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma 20 years after endometrioid adenocarcinoma surgery: A case report

Late pulmonary metastasis from endometrioid adenocarcinoma (EA) is rare, and occurrence after >20 years is extremely rare. Here, we report a case of pulmonary metastasis with coexisting pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma that occurred 20 years after surgery for EA. A 60-year-old Japanese woman had previously undergone surgery for primary EA, and 20 years later presented with an abnormality that was detected on chest radiography. Chest computed tomography (CT) revealed two nodules in the right lower lung lobe, which were suspected to be primary lung cancer. Wedge resection was performed, and the intraoperative pathological diagnosis was that of adenocarcinoma with MALT lymphoma; this prompted additional right lower lobectomy. The final pathological diagnosis was pulmonary metastasis from EA with coexisting MALT lymphoma. This is probably the first report on late pulmonary metastasis coexisting with MALT lymphoma 20 years after surgery for EA. Surgeons should be aware of the possibility of late pulmonary recurrence of EA after more than 20 years and should consider aggressive resection. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: Although extremely rare, pulmonary metastasis can occur more than 20 years after surgery for endometrioid adenocarcinoma. Furthermore, pulmonary metastasis from endometrioid adenocarcinoma may coexist with mucosa-associated lymphoid tissue lymphoma. WHAT THIS STUDY ADDS: Endometrioid adenocarcinoma requires long-term postoperative follow-up to detect recurrence, even in early-stage cases. Video-assisted thoracoscopic surgery (VATS) is useful for resecting pulmonary metastasis from endometrioid adenocarcinoma.

Long-Term Outcomes of Pulmonary Metastasectomy for Uterine Malignancies: A Multi-institutional Study in the Current Era

BACKGROUND

Information on pulmonary metastasectomy (PM) for uterine malignancies in the current era is limited. In the present study, we analyzed the clinical course and results of PM for uterine malignancies in the era of modern imaging diagnostics to clarify the role of PM in the current era in a multi-institutional setting.

METHODS

Fifty-seven patients who underwent PM for uterine malignancies between 2006 and 2015 were retrospectively reviewed. The short- and long-term outcomes, along with factors associated with the prognosis, were analyzed. Details of the clinical course after PM were described.

RESULTS

The mean age of patients was 59.4 years. The primary tumor was located in the uterus corpus in 34 cases (60%) and in the uterus cervix in 23 cases (40%). The median disease-free interval (DFI) was 32 months. Forty patients (70%) received fluorine-18-2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography before PM, and complete resection was achieved in 52 patients (91%). Postoperative complications occurred in 4 patients (7%). Of the 52 patients who underwent complete resection of pulmonary metastases, 28 experienced recurrence, and among these, 17 (60%) underwent local therapy, including six repeat PMs. Among the 52 patients who underwent complete resection, the 5-year relapse-free survival rate was 40.7% and the 5-year overall survival (OS) rate was 68.8%. The univariate analysis revealed that a DFI of ≤ 24 months was associated with significantly poorer OS.

CONCLUSIONS

PM for uterine malignancies is safe and provides favorable long-term outcomes in selected patients. Patients with a DFI of > 24 months have better OS and are good candidates for PM.

[Progress in Surgery for Pulmonary Metastases]

Lung is the most common metastatic site for tumors other than the liver. Pulmonary metastasectomy is also one of the common operations in thoracic surgery. However, the effect of pulmonary metastasectomy is controversial. As far as the current experience is concerned, patients with pulmonary metastases with long disease free interval, low-grade malignant tumor and complete excision have the greatest benefit from metastasectomy. This review is about the progress of surgical treatment of pulmonary metastases.

Correlates of cervical cancer screening uptake among female under graduate students of Aksum University, College of Health Sciences, Tigray, Ethiopia

OBJECTIVES

Cervical cancer is among the leading cancer related causes of morbidity and mortality of women in the world. Ethiopia is among the highest risk countries with age adjusted incidence of cervical cancer 35.9 per 100,000 women or 7619 new cases and 6081 deaths of cervical cancer each year. The aim of this study was to examine correlates of cervical cancer screening uptake among female under graduate students of Aksum University, College of Health Sciences. Data was collected using self-administered structured questionnaire. Variables that were statistically significantly associated with the outcome in bivariate analyses were considered in a logistic multivariate regression analysis.

RESULT

Only 17.2% of students were screened for cervical cancer in their lifetime. Both in bivariate and multivariate analysis, sexual experience (AOR = 38.85; 95% CI [8.907, 169.51]), marital status (AOR = 3.481; 95% CI [1.167, 10.380]), Ppace of birth (AOR = 3.359; 95% CI [1.559, 7.235]), and student's year of study (AOR = 0.005; 95% CI [0.001, 0.031]) were the only correlates of cervical cancer screening uptake among female students. Therefore, the overall cervical cancer screening uptake was low and further study should be done other correlates.
