Online ahead of print. ABSTRACT Prostate cancer (PCa) is one of the most common cancers worldwide but it presents many subtypes and patient heterogeneity. It is necessary to discriminate localised not aggressive PCa and metastatic cancer in order to better define the personalised treatment. The identification of an appropriate biomarker to combine with Gleason grading system, that is one of the mos t important prognostic factors in prostate cancer outcome, remains a major clinical issue. We have tested AT-rich interactive domain 1A (ARID1A) in prostate tissue is order to verify its possible role as morphological marker for prostate cancer progression. ARID1A is a tumour suppressor protein playing a pivotal role in chromatin remodelling during transcriptional regulation. It was decreased in many cancers correlating with tumour aggressiveness. Our data shown that ARID1A had a nuclear staining and that it is significantly decreased in prostate cancers suggesting that it can be involved in this neoplasm but it is not able to discriminate prostate cancer progression.

Transient Receptor Potential Vanilloid 3 Expression Is Increased In Non‐Lesional Skin Of Atopic Dermatitis Patients

xlomafota13 shared this article with you from Inoreader Transient Receptor Potential Vanilloid 3 Expression Is Increased In Non‐Lesional Skin Of Atopic Dermatitis Patients Via Experimental Dermatology Abstract TRPV3 (transient receptor potential vanilloid 3) is a pro-inflammatory ion channel mostly expressed by keratinocytes of the human skin. Previous studies have shown that the expression of TRPV3 is markedly upregulated in the lesional epidermis of atopic dermatitis (AD) patients suggesting a potential pathogenetic role of the ion channel in the disease. In the current study, we aimed at defining the molecular and functional expression of TRPV3 in non-lesional skin of AD patients as previous studies implicated that healthy-appearing skin in AD are markedly distinct from normal skin with respect to terminal differentiation and certain immune function abnormalities. By using multiple, complementary immunolabeling and RT-qPCR technologies on full-thickness and epidermal shave biopsy samples from AD patients (lesional, non-lesional) and healthy volunteers, we provide the first evidence that the expression of TRPV3 is markedly upregulated in non-lesional human AD epidermis, similar to les ional AD samples. Of further importance, by using the patch-clamp method on cultured healthy and non-lesional AD keratinocytes, we also show that this upregulation is functional as determined by the significantly augmented TRPV3-specific ion current (induced by agonists) on cultured non-lesional AD keratinocytes when compared to healthy ones.

xlomafota13 shared this article with you from Inoreader Laryngectomy-free survival after salvage partial laryngectomy: a systematic review and meta-analysis Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 17. doi: 10.1007/s00405-022-07257-2. Online ahead of print. ABSTRACT PURPOSE: Radiotherapy (RT) is widely used for early glottic cancer. Patients failing this treatment are referred to surgical management of their disease. Salvage partial laryngectomy (SPL) has the advantage of preserving laryngeal function with total laryngectomy (TL) remaining as a last resort. The purpose of this study was to determine the efficacy of SPL in preventing total laryngectomy, following failed RT, for early glottic cancer. METHODS: A meta-analysis of all published English literature was performed. All publications that included patients undergoing SPL were reviewed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) reporting guidelines. The search strategy identified 154 relevant articles. A total of 15 retrospective studies that included 323 suitable patients were subseq uently analyzed in this meta-analysis. The main outcome measure was the rate of laryngectomy-free survival (LFS) following SPL. The indications for salvage TL (i.e., disease recurrence and poorly functional larynxes) as well as subgroup analyses for open and trans-oral SPLs were also calculated. RESULTS: The overall rate of LFS following SPL was 81.2% (fixed effects model range: 75.7-86.8%). Salvage TL following SPL were performed in 96.8% due to disease recurrence and in 3.2% to poorly functional larynxes. A subgroup analysis showed a 90.4% LFS after open SPL and 78.6% following trans-oral SPL. CONCLUSION: A high rate of successful salvage partial laryngectomies, regardless of surgical technique, is to be anticipated in well-selected patients after RT failure.

How Often Does Retrieval of a Clipped Lymph Node Change Adjuvant Therapy Recommendations? A Prospective, Consecutive, Patient Cohort Study

xlomafota13 shared this article with you from Inoreader How Often Does Retrieval of a Clipped Lymph Node Change Adjuvant Therapy Recommendations? A Prospective, Consecutive, Patient Cohort Study Via radioactive iodine Ann Surg Oncol. 2022 Jan 18. doi: 10.1245/s10434-022-11324-7. Online ahead of print. ABSTRACT BACKGROUND: Prior studies examining sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) for cN1 patients have demonstrated that 20% of biopsied, clipped lymph nodes (cLNs) are nonsentinel lymph nodes (non-SLNs). Our goal was to determine how often the cLN was a non-SLN among both cN0 and cN1 patients and how often cLN pathology impacted management. METHODS: Overall , 238 patients treated with NAC and surgery January 2019 to June 2020 were prospectively examined. Patients underwent routine axillary ultrasound, biopsy of suspicious nodes, and clip placement. Radioactive iodine-125 seed localization of the cLN was performed in cN1 patients only. Isolated tumor cells (ITCs) were considered node positive (ypN+) for both cN0 and cN1 cohorts. Chart review was performed to determine if cLNs were non-SLN and their ypN status. RESULTS: Of 118 cN0 patients, 115 of 118 (97%) underwent successful SLNB, 33 of whom had a cLN present; 21 of 33 (64%) cLNs were non-SLNs. Overall, 9 of 118 (8%) were ypN+; no cLN was ypN+ without additional +SLNs. Of 120 cN1 patients, 104 of 120 (87%) converted to cN0, 98 of 104 (94%) of which had attempted SLNB, and 95 of 98 (97%) successfully mapped. The cLN was a non-SLN in 18 of 95 (19%). Overall, 58 of 104 (56%) cN1 patients were ypN+. One patient had a positive cLN in the absence of +SLNs. This patient underwent axill ary lymph node dissection (ALND); adjuvant treatment recommendations were unchanged. CONCLUSIONS: The cLN was a non-SLN in 19% of cN1 patients. cLN pathology did not impact adjuvant therapy recommendations, calling into question the utility of routinely clipping biopsied lymph nodes.

Occult lymph node metastasis in the contralateral neck of oropharyngeal squamous cell carcinoma: a meta-analysis and literature review

xlomafota13 shared this article with you from Inoreader Occult lymph node metastasis in the contralateral neck of oropharyngeal squamous cell carcinoma: a meta-analysis and literature review Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 18. doi: 10.1007/s00405-021-07230-5. Online ahead of print. ABSTRACT PURPOSE: The purpose of this study was to determine whether contralateral cervical lymph node dissection is needed in patients with oropharyngeal squamous cell carcinoma (OPSCC) with contralateral cervical cN0. METHODS: We searched the PubMed, Web of Science, Embase, Chinese Biomedical Literature Database (CBM) and Cochrane Library databases up to August 14, 2021 for studies examining the contralateral neck occult metastasis rate of patients with ipsilateral clinical neck-negative (cN0) OPSCC and the contralateral neck occult metastasis rate of patients with ipsilateral clinical neck-positive (cN1, cN2a, cN2b) OPSCC. This rate is used to determine whether patients with contralateral cN0 OPSCC need contralateral cervical lymph node dissection. RESULTS: A total of 14 articles, including 532 cases, were included in the anal ysis. When studying the rate of ipsilateral cervical occult metastasis in patients with ipsilateral cN0, 163 cases were included in 11 studies. The results showed that the rate of contralateral cervical occult lymph node metastasis in patients with ipsilateral cN0 was 0.6816% (95% CI 0.0000-4.4880 (P = 0.3005)). In the study of ipsilateral cN+ (cN1, cN2a, cN2b), a total of 369 cases of 10 articles were included in the analysis. The results showed that the rate of contralateral cervical occult lymph node metastasis in patients with ipsilateral cN+ was 11.4920% [95% CI 7.8944-15.5223 (P = 0.0000)]. CONCLUSION: For cancer treatment, the ultimate goal is to achieve the best control of cancer and the lowest complications. It seems unnecessary to intervene in the contralateral neck of patients with OPSCC with ipsilateral cN0. For OPSCC with ipsilateral cN+ , this index is a factor that cannot be ignored when making clinical decisions. PMID:35041065 | DOI:10.1007/s00405-021-07230-5 View on the web Inoreader.
