ABSTRACT

Objective: To evaluate the roles of G Protein-Coupled Receptor 68 (GPR68) and tumor infiltrating lymphocytes (TIL) in TPF-(paclitaxel, cisplatin and 5-fluorouracil) induced chemotherapy for middle-advanced hypopharyngeal squamous cell carcinomas. Methods: A total of 31 patients with middle-advanced hypopharyngeal squamous cell carcinoma before TPF-inducted chemotherapy were enrolled from September 2012 to November 2017 in Beijing Tongren Hospital, Capital Medical University, including 28 males and 3 females, aged 43 to 71 years old. The expression of GPR68 and tumor infiltrating CD4+and CD8+T cells before chemotherapy was detected by immunohistochemical staining, and the relationships between GPR68 expression and clinical features, chemotherapy efficacy and overall survival (O S) were analyzed using t-test. Results: After 3 cycles of chemotherapy, there were 4, 14, 10 and 3 patients respectively with complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). The positive rates of GPR68 and CD8 were 25% and 40% respectively in the effective group (CR+PR), while 50% and 15% in the ineffective group (SD+PD), with statistically significant differences between two groups (t=5.17 and 12.86,P<0.001). Linear regression analysis showed that GPR68 was negatively correlated with CD8+T cells (r=-0.64,P<0.001). There was no significant correlation between the CD4 expression and TPF efficacy (P>0.05). The mean OS was 12.5 months in patients with high-expressed GPR68 and 25.0 months in patients with low-expressed GPR68, with a statistically significant difference (P=0.005). And mean OS was 25.0 months in patients with high-expressed CD8 and 14.5 months in lo w-expressed CD8, with a statistically significant difference (HR=2.58, P=0.019). Cox regression analysis showed that GPR68 and CD8+T cells were significant prognostic factors (OR(95%CI)=3.27(2.46-5.97) and 1.53(0.78-1.82), all P<0.05), while CD4 had no significant effect on prognosis (P>0.05). Conclusion: GPR68 and CD8+T cells are expected to be biomarkers for evaluating the efficacy and prognosis of TPF-induced chemotherapy in patients with middle-advanced hypopharyngeal squamous cell carcinoma.

Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2022 Feb 7;57(2):185-190. doi: 10.3760/cma.j.cn115330-20210331-00165.

ABSTRACT

Objective: To investigate the effects of adipose-derived mesenchymal stem cells (ADMSCs) on proliferation and hormone secretion of parathyroid cells in votro. Methods: The parathyroid cells and ADMSCs were obtained from 10 SD rats by cell separation and culture. The phenotype of P3 generation for ADMSCs was detected by flow cytometry. The co-culture of parathyroid cells and ADMSCs was conducted in the ratios of 2∶1, 1∶1, 1∶2 and 1∶5, respectively. The level of parathyroid hormone in cell supernatant was determined. The results were compared with the parathyroid hormone in the supernatant of parathyroid cells cultured separately in the corresponding number. The effects of ADMSCs on the hormone secretion of parathyroid cells were evaluated. SPSS 11.0 software was used for statistical analysis . Results: The primary culture of either parathyroid cells or ADMSCs and the co-culture of these cells in vitro were performed successfully, and the in vitro culture of different proportions of the two cells showed different effects on parathyroid hormone secretion. The co-culture of parathyroid cells and ADMSCs, especially in the ratio of 1∶5, facilitated the secretion of parathyroid hormone ((1.3±0.0) vs. (0.8±0.1), (1.3±0.0) vs. (0.9±0.0), (1.7±0.5) vs. (0.9±0.0), (1.7±0.0) vs. (1.2±0.2))ng/L with t value of 25.46, 64.30, 3.32, 7.16, P<0.05 on the 2nd, 4th, 6th and 8th days respectively. Secondly, when the ratio was 1∶2, the PTH level showed an upward trend. Conclusion: Parathyroid cells and ADMSCs can be co-cultured in vitro, facilitating the secretion of parathyroid hormone under the appropriate cell proportion such as the ratio of by parathyroid cells to ADMSCs at 1∶5.

Airway management in patients with lingual thyroid: a case report and review of the literature

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Feb 24. doi: 10.1007/s00405-022-07310-0. Online ahead of print.

ABSTRACT

PURPOSE: To review the management of patients with lingual thyroid (LT) causing upper airway obstruction and to suggest a diagnostic and therapeutic workflow.

METHODS: A PubMed review of published cases from January 1980 up to December 2020 of LT causing upper airway obstruction. We selected cases of confirmed LTs that presented with non-state-dependent airway obstruction. An illustrative case report is presented.

RESULTS: Twenty-one articles fulfilling the inclusion criteria were found, reporting 24 cases (7 neonatal, 2 pediatric and 15 adults). The main presenting symptoms was dyspnea with increased work of breathing, followed by dysphagia and stridor most commonly in neonates. At least one imaging modality was performed in all patients. Thyroid function was altered in half the patients and normal in the other half. Th e LT was the only thyroid tissue in all cases except 2. Altogether, 5/24 patients required tracheostomies and two-thirds of the patients underwent surgical resection of the LT (mostly transoral). Also 2/3 of the patients received thyroid replacement therapy. After a median follow-up of 17 months, airway symptoms had fully resolved for all patients but one.

CONCLUSION: While rare, ectopic LTs should be considered in the differential diagnosis of stridor, dyspnea and airway obstruction. In neonates, concomitant presence of hypothyroidism on neonatal screening and airway obstruction should prompt the search for a LT. Early identification and thyroid replacement therapy seem to significantly relieve symptoms of upper airway obstruction, but severe obstruction and concomitant airway lesions may require more definitive management approaches.

SocialThumb.00008390.DC.jpeg

Objective Treatment for advanced melanoma after progression on immunotherapy is limited. This phase II trial (NCT03422445) was conducted to evaluate the efficacy and safety of apatinib plus temozolomide in patients with advanced melanoma after failure of immunotherapy. Methods Patients with unresectable stage III or stage IV melanoma after progression on immunotherapy were treated with temozolomide 300 mg on days 1–5 and apatinib 500 mg daily every 28-day cycle until disease progression or intolerable toxicities. Besides immunotherapy, prior chemotherapy, targeted therapy, and clinical trials were allowed. The primary endpoint was progression-free survival. Secondary endpoints were objective response rate, disease control rate, overall survival, and safety. Results Of 29 patients, 28 (96.6%) had metastatic diseases, and the predominant subtypes were mucosal [12 (41.4%)] and acral melanoma [eight (27.6%)]. Five (17.2%) patients showed BRAF, CKIT, or NRAS mutation. Five achieved confirmed partial response, with an objective response rate of 17.2%. The disease control rate was 82.8%. The median progression-free survival was 5.0 months [95% confidence interval (CI): 4.7–5.3], and the median overall survival was 10.1 months (95% CI: 5.1–15.0). Grade 3–4 treatment-related adverse events included proteinuria [four (13.8%)], thrombocytopenia [two (6.9%)], hypertension [one (3.4%)], and hyperbilirubinemia [one (3.4%)]. No treatment-related death occurred. Conclusion Apatinib plus temozolomide demonstrated promising efficacy and manageable safety profile in patients with advanced melanoma after progression on immunotherapy. * Li Zhou and Yue Yang contributed equally to the writing of this article and are the co-first authors.
