Factors effective on recurrence and metastasis in phyllodes tumors

Background and Aim

Phyllodes tumors (PT) are rare biphasic breast tumors containing stromal mesenchyme and epithelial components. It was classified as benign, borderline, and malignant by the World Health Organization (WHO). Although there is no certainty about the size of the desired margin in the surgery to be applied, a tumor-free area of 1 cm is often targeted. Our study aimed to determine the subtype rates in patients with PT and evaluate the surgical margin, recurrence, and survival times obtained after the surgery.

Patients and Methods

This study was conducted at Seyhan Goverment Hospital and involved the PT patients treated between January 2010 and June 2020. We analyzed PT patients retrospectively. Sixty-one patients with PT were analyzed. In the patient, demographic characteristics, body mass index (BMI), surgical procedures, tumor type, size, mitosis rate, and distance of tumor to surgical margin were evaluated. During follow-up, reoperation, recurrence, metastasis, survival times, and mortality rates were evaluated.

Results

Sixty-one phyllodes breast tumor patients whose histopathology was reported as malignant, borderline, and benign were evaluated and presented in our study. The mean age was 37.84 (15-100), and the BMI was 25.78 (±5.35) mm. Of the 61 patients, 41 (67.2%) were diagnosed with benign phyllodes tumor (BPT), 10 (16.4%) as borderline phyllodes tumor (BLPT), and 10 (16.4%) as malignant phyllodes tumor (MPT).

Conclusions

Preoperative diagnosis of PT can reduce the rate of secondary surgical procedures and the loss of extra breast tissue. A large diameter needle and sufficient number of tissue samples for preoperative core biopsy may increase the rate of accurate diagnosis.

Chronic appendicitis: the process from pre-diagnosis to pathology

OBJECTIVE

Chronic appendicitis (CA) is a rare medical condition. CA is characterized by a less severe and almost continuous abdominal pain. It has a clinical picture lasting longer than 1-2 days and extending over weeks, months, even years. The exact etiology of CA is unclear. Certain resources have reported it as the cause of partial obstruction in the lumen of the appendix.

PATIENTS AND METHODS

Our study was carried out with the approval of the Clinical Research Ethics Committee. A retrospective analysis was performed between August 2018 and March 2020.

RESULTS

It was determined that 207 appendectomies were performed during the retrospective scan period. The data of 182 of these patients could be accessed fully and we could get answers to the criteria we thought. Only 8 of the patients screened were likely to be diagnosed with chronic appendicitis in the preoperative period. CA was found in 1 of the 8 patients (12.5%) who underwent surgery after a preliminary diagnosis of CA. Two patients were reported as malignant (25%), 3 patients (37.5%) as reactive lymphoid hyperplasia, and 1 patient as peri appendicitis (12.5%). Bleeding and congestion were reported in the last patient (12.5%).

CONCLUSIONS

The diagnosis of chronic appendicitis is made by pathological examination. It may not always be possible to consider "chronic appendicitis" as a preliminary diagnosis. This should still be kept in mind. In our opinion, it is a bit difficult to make a preliminary diagnosis of chronic appendicitis and make a surgical decision. We believe that controlled and prospective studies can shed more light on chronic appendicitis.

Assessment of left atrial volume and mechanical functions using real-time three-dimensional echocardiography in patients with mitral annular calcification

Objective:

Mitral annular calcification (MAC) is degeneration of the fibrous annular ring of the mitral valve. Left atrial (LA) function and volume have been evaluated by many methods; however, none have used real-time three-dimensional echocardiography (RT3DE) in patients with MAC. Our study is the first to evaluate LA volume and mechanical function using RT3DE in patients with MAC.

Methods:

Our study was a prospective cross-sectional study. In total, 32 patients with echocardiographic evidence of MAC and 30 volunteers without MAC were enrolled in the study. Kolmogorov–Smirnov test, Student’s t-test, Mann-Whitney U test, chi-square test, Pearson’s correlation test, and multiple linear regression analyses were used in this study.

Results:

LA diameter was significantly higher in patients with MAC (38.5±3.8 vs. 31.1±2.9, p<0.001). Maximum LA volume (49.6±11.2 vs. 35.6±2.5, p<0.001), minimum LA volume (23.8±7.9 vs. 12.6±2.3, p<0.001), and LA volume index (LAVI) (26.9±6.1 vs. 20.5±2.4, p<0.001) were also higher in the MAC group. LAVI was correlated with age (p<0.001), blood urea nitrogen levels (p=0.089), total cholesterol levels (p=0.055), left ventricular systolic myocardial velocity (p=0.048), E/A ratio (p<0.001), and MAC (p<0.001). Multiple linear regression analyses revealed that age (β=0.390, p<0.001) and MAC (β=0.527, p<0.001) were independent predictors of LAVI.

Conclusion:

We found that LA mechanical function was impaired in patients with MAC. Furthermore, age and MAC were independent predictors of increased LAVI according to our RT3DE examination.

Acromesomelic dysplasia with cardiac and neurologic abnormalities: an association by chance, new features of maroteaux type or a new syndrome?

We report a patient with acromesomelic dysplasia, cardiac and neurologic abnormalities. This may be a new syndrome or cardiac and neurologic features may be undescribed rare features of acromesomelic dysplasia.
