Incidental radiologic findings at breast cancer diagnosis and likelihood of disease recurrence.

ABSTRACT: Despite guidelines recommending against its routine use, perioperative imaging for distant metastases is frequently performed in newly diagnosed breast cancer patients, uncovering incidental findings of uncertain significance. We assessed the clinical significance of incidental findings by determining if their presence is associated with disease recurrence. A retrospective review of staging imaging was performed in patients with stage II or III invasive breast cancer diagnosed during 2008-2009 at a large academic medical center. Data related to perioperative imaging and disease recurrence were abstracted from the medical record. Kaplan-Meier curves and Cox proportional hazards models were used to assess the association between incidental findings and time to disease recurrence. A total of 169 of 340 patients (49.7 %) underwent staging evaluation for distant metastases (CT chest, abdomen, pelvis, bone scan, and/or PET-CT). Of these, 146 (86.4 %) had at least one suspicious or indeterminate finding. Follow-up studies were performed in 73 (43.2 %) patients. Nineteen patients were diagnosed with metastatic disease at diagnosis, 18 of whom had stage III disease. In patients without metastatic disease at diagnosis, 32 later developed recurrence. Non-calcified pulmonary nodules were associated with shorter time to disease recurrence (hazard ratio 2.51, 95 % CI 1.13-5.57, p = 0.02). Imaging for distant metastases frequently reveals indeterminate findings, most of which are not associated with disease recurrence. The association between pulmonary nodules and recurrence warrants validation in an independent cohort. Overall, these findings support current guidelines recommending against routine extent of disease evaluation in patients with newly diagnosed stage II breast cancer.

Project description:Background: Whether girls with central precocious puberty (CPP) should undergo routine brain magnetic resonance imaging (MRI) to identify potential intracranial pathologies is controversial. Aims: To evaluate the brain MRI results of girls with CPP and identify the clinical and endocrine predictors of brain abnormalities. Methods: This retrospective study obtained data from pediatric endocrine clinics at Chang Gung Children's Hospital. From 1997 and 2017, 403 girls were consecutively diagnosed with CPP. After the exclusion of patients with a history of central nervous system (CNS) insults or associated neuropsychiatric symptom or signs, we studied the prevalence of brain abnormalities in 251 girls with CPP who received detailed MRI examinations of the hypothalamus and pituitary area. We also recorded the demographic data of the participants, including the onset of puberty; initial pubertal status; height; weight; uterus and ovary sizes; and basal luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol levels, and the response to GnRH stimulation test. Results: Among the 251 girls with CPP, we observed no brain alterations in 190 (75.70%), abnormalities in the hypothalamic-pituitary (H-P) area in 54 (21.51%), and abnormalities in the non-H-P area in 7 (2.79%). Among the 54 patients that had H-P lesions, we noted pathological findings related to CPP (hypothalamic hamartoma) in only one (0.4%) girl aged below 6 years old. We also identified incidental findings in the other girls with H-P lesions, including non-functioning pituitary microadenomas (12.35%), pituitary pars intermedia cysts (4.38%), Rathke's pouch cysts (1.99%), pituitary hypoplasia (1.59%), and pineal gland cysts (0.8%). The patients that had non-H-P lesions were found to have arachnoid cysts (1.59%), Chiari I malformation (0.4%), prepontine nodule (0.4%), and choroidal fissure cyst (0.4%). Of all the patients with brain lesions, 45 (73.77%) underwent regular MRI follow-up. While none of the H-P and non-H-P lesions showed progression, 19.67% of these regressed during the follow-up. None of the participants exhibited other hormonal abnormalities or underwent surgery. Conclusion: The prevalence of true pathological brain lesions related to CPP in girls without prior symptoms or signs of CNS lesions was low (0.4%). None of the girls with intracranial lesions required further intervention besides the GnRH agonist treatment. These data question the routine use of brain MRI in all girls with CPP, especially in those who are healthy without neurologic symptoms.
