Objectives: There is currently no consensus regarding the optimal site-specific postoperative follow-up duration for patients with completely resected non-small cell lung cancer. Long-term surveillance for recurrence may lead to psychological distress or economic burdens for patients.We aimed to propose an appropriate site-specific follow-up strategy for patients with non-small cell lung cancer based on 10-year follow-up data.
Materials And Methods: We analyzed recurrence patterns in 2,359 patients with non-small cell lung cancer who underwent surgical resection from 2008 to 2013. We established potential site-specific follow-up endpoints when the subsequent recurrence rates fell below 5% and proposed a corresponding follow-up strategy.
Results: With a median follow-up of 111.0 months, postoperative recurrences were observed in 985 patients (41.8 %). We identified several factors associated with site-specific recurrence recurrence patterns, including ground-glass opacity component, sex, histology type, and pathological TNM stage. No recurrence was observed in patients with pure ground-glass nodules, a consolidation-to-tumor ratio less than 0.5, or a pathological type classified as lepidic pattern-predominant adenocarcinoma. In thorax, brain and bone, patients with non-squamous cell carcinoma exhibited higher recurrence rates than those with squamous cell carcinoma. In abdomen and neck, male patients have a higher recurrence rate than female patients, particularly within the pathological stage III group.
Conclusions: The follow-up strategy was developed based on the recurrence patterns analyzed from ten-year follow-up data. The online tool may assist in determining the optimal site-specific duration for surveillance based on clinicopathologic features.

Background: Peripheral artery disease (PAD) is widely prevalent, affecting more than 200 million people worldwide. However, the natural history of this disease process following lower extremity revascularization has not been fully delineated. We aimed to analyze this disease process with particular attention to subsequent interventions, wound complications, and mortality.

Technologists must assure the accuracy and precision of pulmonary function equipment prior to testing patients. This study aimed to identify the sources of failure and unacceptable submission rates for spirometry volume linearity and syringe diffusing capacity of the lung for carbon monoxide (D) check quality control (QC). In addition, we explored whether the time between training and first QC submission affected overall percentage of unacceptable submissions.

Introduction: Using a nationwide population-based cohort, we primarily investigated whether overall and site-specific cancer risks are increased in patients with acromegaly.
Patients And Methods: The study included 2382 patients with acromegaly and 11 910 controls aged above 20, from 2006 to 2016. Cox hazards regression analysis was used, adjusting for baseline covariates.

Colloid nodules are common and benign thyroid lesions that usually progress slowly and are asymptomatic. It requires follow-up because untreated colloid nodules may develop into malignant tumor. The study aimed to examine the contributions of vitamin D receptor (VDR) expression, VDR/FokI (rs2228570) genotypes, and serum vitamin D level to the susceptibility to colloid nodules.
