Indeterminate pulmonary nodules and prior malignancy: survival and recurrence after surgery in newly diagnosed stage I non-small cell lung cancer.
Article in Journal of thoracic disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Surgical excision biopsy remains the only reliable option in most cases of indeterminate pulmonary nodules, particularly in cancer survivors for whom surgery provides local control of pulmonary metastasis and the best chance of cure for early-stage lung cancer. Nevertheless, unnecessary surgeries remain a concern and the prognosis of newly diagnosed lung cancer might be influenced by the history of previous malignancy. We aimed to analyze the outcomes of resected indeterminate pulmonary nodules in patients with and without previous malignancy, and the impact of prior cancer history on survival and recurrence in stage I non-small cell lung cancer (NSCLC) patients. Methods: We retrospectively studied 176 resected indeterminate pulmonary nodules from 169 patients (58% with and 42% without previous cancer). Recurrence and overall survival (OS) were analyzed in newly diagnosed stage I NSCLC using the Kaplan-Meier method and Cox proportional hazard models. Results: The rate of benign lesions was 15.3% (9.6% in the previous cancer group and 23.6% in the no previous cancer group). In stage I NSCLC patients (n=86), previous malignancy was associated with recurrence (P<0.001) but not OS (P=0.23). Chronic obstructive pulmonary disease and visceral pleural invasion were associated with impaired OS and recurrence. Mediastinal lymph node removal was associated with better OS. Conclusions: The rate of benign resections among indeterminate pulmonary nodules in the no-previous cancer group more than doubled that of the previous cancer group and, in newly diagnosed stage I NSCLC patients, recurrence was independently associated with prior cancer. Therefore, in this setting, a history of previous malignancy should be taken into consideration when identifying patients at risk of tumor recurrence.
