Survival and prognostic factors of isolated pulmonary metastases originating from colorectal cancer: An 8-year single-center experience.

ABSTRACT:

Background

Isolated pulmonary metastasis (IPM) is a rare entity that accounts for 10% of pulmonary metastases seen in colorectal cancer (CRC). This study aims to evaluate the overall 5-year survival of IPM originating from CRC and identify potential prognostic factors affecting the overall survival (OS).

Methods

A retrospective cohort study conducted in a tertiary care center. The study included all patients diagnosed with CRC aged 18-75 years who underwent primary tumor resection with curative intent between 2008 and 2015, and developed IPM. Patients with no follow-up and those with extra-pulmonary metastases were excluded.

Results

The prevalence of IPM in the overall CRC cases was 4.18% (20/478 patients). The mean age of patients with IPM was 52.7 ± 12.9 years. Ten patients had synchronous IPM (50%), thirteen had unilateral (65%), and eleven underwent metastasectomy (55%). The 5-year OS was 40%, and the mean OS was 3.12 ± 1.85 years. Several factors were found to be associated with a favorable outcome, which include unilateral IPM (3.69 vs. 2.07 years; P = 0.024), metachronous (4.25 vs. 2.14 years; P = 0.017), metastasectomy (4.81 vs. 1.83 years; P = 0.005). In addition, mortality was likely to be decreased by more than 90% after metastasectomy (unadjusted odds ratio = 0.071; 95% confidence interval [CI] = 0.01-0.8; P = 0.032).

Conclusions

Forty percent of the included patients survived the 5-year follow-up. Better survival was associated with the metastases being unilateral, metachronous, and metastasectomy. Mortality was lower in patients with pulmonary recurrence after metastasectomy.

Project description:ObjectiveWe aimed to review symptoms, findings, surgical treatment options, short- and mid-term outcomes, and reoperation rate of patients diagnosed with of left coronary artery from the pulmonary artery (ALCAPA) of an anomalous origin in our institution.MethodsFrom May 2000 to March 2018, 33 patients who had left coronary artery originating from the pulmonary artery were retrospectively examined. The clinical features of patients, diagnostic tools and their efficacy, outcomes of surgical repair, and problems during follow-up were evaluated.ResultsThirty-three patients (22 females, 11 males) were included in the study. At the time of surgery, the median age and weight of patients were 6 months (minimum/maximum, 1-166 months) and 6.5 kg (minimum/maximum, 3-38.5 kg), respectively. The mean follow-up was 5±3.5 years (range, 1-16 years). Dyspnea, tachypnea, diaphoresis, prolonged feeding time, and developmental delay were common presenting signs and symptoms. It was determined that all the patients who were diagnosed at another center reached our center for surgical treatment within 1 month. Twenty-three (69.7%) patients had pathologic Q wave with anterior and/or anterolateral myocardial infarction signs on an electrocardiogram (ECG), whereas 22 (66.6%) patients had ST-T segment changes. Twenty-one (63.6%) patients had cardiomegaly on the telecardiogram. A reimplantation surgery was performed to 22 patients and 10 patients underwent the Takeuchi procedure. In addition to ALCAPA repair, 5 patients needed mitral valve plasty. Atrial septal defect (ASD) and ventricular septal defect (VSD) were closed in one patient, and Tetralogy of Fallot was totally corrected in another. At discharge, there was a significant improvement in left ventricular (LV) systolic functions. At the last visit, all patients had normal LV systolic functions except four who had mild dysfunction. The mean follow-up of the four patients was 2.8 years. In the early postoperative period, complications were seen in 10 patients. Five patients died in the early postoperative period, while one patient died 9 months after the ALCAPA surgery because of low cardiac output syndrome that developed after mitral repair.ConclusionPatients with ALCAPA commonly present with congestive heart failure symptoms. When the diagnosis is confirmed in these patients, surgical treatment should not be delayed. The availability of surgical center and surgery outcomes for ALCAPA diagnosed patients are comparable with other countries, but the delay in the diagnosis of disease is still a problem in our country.
