Relevance of Intraparotid Metastases in Head and Neck Skin Squamous Cell Carcinoma

xlomafota13 shared this article with you from Inoreader

Objectives

Parotid lymph node metastases are common in head and neck cutaneous squamous cell carcinoma (cSCCHN). Here we evaluate the diagnostic, prognostic, and therapeutic implications of intraglandular lymph node (IGLN) metastases in cSCCHN.

Study Design

Retrospective study in a tertiary referral university cancer institute.

Methods

We included patients with cSCCHN who underwent parotidectomy and neck dissection (ND), with or without synchronous resection of the skin primary, between January 1999 and January 2018. The characteristics of cSCCHN with or without IGLN involvement were compared.

Results

Altogether, 68 patients were included. Of the 29 (42.6%) patients classified as cN0, eight were upstaged pN+ and had concomitant IGLN involvement. Of 21 patients with pN0 disease, IGLN metastases were absent in only three cases, resulting in a specificity and sensitivity of parotid metastases to diagnose occult nodal neck metastases of 14.29% and 100%, respectively. The positive and negative predictive values were 14.29% and 100%, respectively. Univariate analyses only displayed a significantly higher rate of moderately and poorly differentiated primaries in patients with IGLN metastases (P = .015). Only advanced T‐stages were significantly associated with neck recurrences.

Conclusion

IGLN status in advanced cSCCHN is potentially predictive for occul nodal neck metastases. Our results suggest that ND in patients with histopathologically negative IGLNs and clinically negative neck lymph nodes may not be necessary given the high negative predictive value of IGLN status in this group of patients. Therefore, accurate diagnostic evaluation of IGLN involvement is mandatory.

Primary Hyperparathyroidism During Pregnancy Treated With Parathyroidectomy: A Systematic Review

xlomafota13 shared this article with you from Inoreader

Objectives/Hypothesis

The primary objective of this study was to assess the safety of parathyroidectomy during pregnancy as treatment for hyperparathyroidism (HPTH) in comparison to nonsurgical management plans. Secondary outcomes involved analyzing the safety of surgery in the third trimester and the benefit of operating on asymptomatic pregnant patients.

Study Design

Systematic review.

Methods

PRISMA‐guided systematic review of all cases of primary hyperparathyroidism during pregnancy published in peer‐reviewed English journals on PubMed/MEDLINE, EMBASE, and SCOPUS from 1980 to 2020.

Results

A total of 75 manuscripts were included in this review describing 382 cases of gestational hyperparathyroidism. The median maternal age was 31 years. Overall, 108 cases (28.3%) underwent parathyroidectomy during pregnancy while 274 cases (71.7%) were treated nonsurgically. The majority of surgeries took place during the second trimester (67.6%). Complications and/or deaths were less likely to occur after surgery in the second trimester (4.48%) as compared to surgery in the third trimester (21.1%). Nine surgically treated cases resulted in infant complications and/or death; however, none of these nine cases had any surgical complications. Despite these complications, the overall infant complication rate for patients who underwent surgical treatment remained lower than that of patients treated with conservative therapy (9.1% vs. 38.9%).

Conclusions

This review suggests that for all pregnant patients with diagnosed HPTH, parathyroidectomy should be considered regardless of symptomatology. Our data suggest that parathyroidectomy is associated with fewer risks than more conservative treatments and results in better fetal outcomes. Surgery during the third trimester is feasible and surgery should be considered in both symptomatic and asymptomatic patients. Laryngoscope, 2021
