Background

The survival rate of head and neck squamous cell carcinoma (HNSCC) patients with secondary primary malignancy (SPM) showed no significant improvement for decades, however, the impact of advances in diagnostic tools is rarely mentioned. This study investigated the clinical characteristic of HNSCC with SPM over a 27-year period especially from the perspective of diagnostic tools.

Methods

This study evaluated 157 HNSCC patients with SPM. The patients were divided into two groups according to the time of SPM diagnosis (Group A:1992–2003; Group B: 2004–2014). Age, gender, stage of first primary malignancy (FPM), SPM interval, overall survival, and disease-free survival were compared between groups.

Results

Group B had significantly more SPM developed rate (p = 0.002), more SPM patients with advanced stage of FPM (p = 0.001), synchronous SPM (p = 0.006), and shorter SPM interval (p Conclusion

Among patients diagnosed with HNSCC recently, more SPMs are diagnosed in a shorter time interval and in a more advanced stage. The overall advances in diagnostic tools cannot significantly improve SPM survival, however, it enables more patients to receive corresponding treatment.

ABSTRACT

We hereby present a rare case of laryngeal zoster presenting with unilateral odynophagia and hemifacial pain in an immunocompetent host. Visualization of the characteristic vesicles is challenging given their short-lived and at times delayed appearance; thus, laryngeal zoster may be a largely unrecognized cause of laryngitis and cranial neuropathies. Heightened aw areness may improve prompt diagnosis, referral and initiation of antiviral therapy, while guiding patient counselling on the associated long-term sequelae such as voice and swallowing impairments, and post-herpetic neuralgia.

Histol Histopathol. 2022 Feb 15:18436. doi: 10.14670/HH-18-436. Online ahead of print.

ABSTRACT

BACKGROUND: Mucinous micropapillary carcinoma (MMPC) is a unique subtype of breast cancer, and there is as yet no detailed report on the clinical characteristics of MMPC.

METHODS: MMPC, pure mucinous breast carcinoma (PMBC), and invasive micropapillary carcinoma (IMPC) samples were enrolled simultaneously, and immunohistochemistry analysis was performed to explore the clinicopathological attributes of MMPC. Moreover, survival analyses of MMPC were performed among the MMPC, PMBC, and IMPC groups and within the MMPC group.

RESULTS: The results showed that MMPC demonstrated distinct pathological features and that vascular invasion and lymph node metastasis were two significant clinical attributes of MMPC. MMPC leads to a shorter survival time than PMBC but an increased survival time compared to IMPC, while the tumor-node-metastasis stage and lymph node metastasis were identified as two independent prognostic elements for disease-free survival in discerning the MMPC prognosis.

CONCLUSIONS: The gathered data implied that further understanding and classification of MMPC may provide better individualized therapeutic strategies for MMPC treatment.

PTH in situ measurement in patients with hyperparathyroidism: single-centre experience of 179 patients

xlomafota13 shared this article with you from Inoreader

Eur J Endocrinol. 2022 Feb 1:EJE-21-1249. doi: 10.1530/EJE-21-1249. Online ahead of print.

ABSTRACT

CONTEXT: The measurement of PTH in situ (PTHis) by fine-needle aspiration (FNA) is proposed as a tool to preoperatively help localize parathyroid glands detected on ultrasound. However, the accuracy of PTHis is highly variable according to the few available studies. We aimed to develop and validate the PTHis procedure. We assessed the performance of PTHis in a large series of patients with hyperparathyroidism.

PATIENTS: The technique setup consisted of PTHis measurement in thyroid samples from patients with thyroid nodules and patients with high circulating PTH levels (tertiary hyperparathyroidism). Consecutive patients were recruited and submitted to ultrasound-guided FNA-PTHis determination.

RESULTS: During the method setup, we obtained undetectable PTHis levels in all non-parathyroid tissues after sample dilutions. PTHis was high er in patients with hyperparathyroidism (n=145, 1817±3739 ng/L, range <4.6-31,140) than in those with thyroid or undetermined cervical lesions (n=34, <4.6 ng/mL,p<0.0001). When evaluating PTHis performance in histologically proven samples (158 lesions from 121 patients), PTHis was detectable in 85/97 parathyroid lesions (87%, range 22-31,140 ng/L) and undetectable in all non-parathyroid lesions (n=61,p<0.0001). The specificity and positive predictive value were 100%, and the sensitivity was 87.6%. False-negative lesions (n=12) were smaller (9.4±5.9 mm) and more often consisted of hyperplasias (75%) than true-positive lesions (16.1±8.4 mm and 33%, p=0.009 and p=0.0089, respectively). The method was safe and well tolerated. Four educational cases are also provided.

CONCLUSIONS: PTHis determination is a safe and well-tolerated procedure that enhances the specificity of ultrasound-detected lesions. If accurately set up, it confirms the parathyroid origin of uncharac terized cervical lesions.
