In-transit metastasis of cutaneous squamous cell carcinoma: report of two cases.

Acta Dermatovenerol Alp Pannonica Adriat 2022 Jun;31(2):75-77

Department of Dermatology and Venereology, Haydarpaşa Numune Training and Research Hospital, Istanbul, Turkey.

Transit metastases include metastatic foci of the skin and subcutaneous tissue located between the tumor and the nearest regional lymph node. Although transit metastases have been described for malignant melanoma, some cases of transit metastases have also been reported among primary cutaneous non-melanoma cancers. Treatment of patients with in-transit squamous cell carcinoma (SCC) is a multimodal approach for advanced staging imaging and therapy, including Mohs micrographic surgery, adjuvant radiation, and possibly sentinel lymph node biopsy and immunotherapy or chemotherapy.

Leukocyte subtyping predicts for treatment failure and poor survival in anal squamous cell carcinoma.

BMC Cancer 2022 Jun 24;22(1):697. Epub 2022 Jun 24.

Department of Surgery, Division of Colorectal Surgery, University of Illinois at Chicago, Chicago, IL, USA.

Background: Anal squamous cell carcinoma (SCC) generally carries a favorable prognosis, as most tumors are highly sensitive to standard of care chemoradiation. However, outcomes are poor for the 20-30% of patients who are refractory to this approach, and many will require additional invasive procedures with no guarantee of disease resolution.

Methods: To identify the patients who are unlikely to respond to the current standard of care chemoradiation protocol, we explored a variety of objective clinical findings as a potential predictor of treatment failure and/or mortality in a single center retrospective study of 42 patients with anal SCC.

γH2AX, a DNA Double-Strand Break Marker, Correlates with PD-L1 Expression in Smoking-Related Lung Adenocarcinoma.

Int J Mol Sci 2022 Jun 15;23(12). Epub 2022 Jun 15.

Department of Diagnostic Pathology, Graduate School of Medicine, Fujita Health University, 1-98 Dengakugakubo, Kutsukake-cho, Toyoake 470-1192, Japan.

In recent years, the choice of immune checkpoint inhibitors (ICIs) as a treatment based on high expression of programmed death-ligand 1 (PD-L1) in lung cancers has been increasing in prevalence. The high expression of PD-L1 could be a predictor of ICI efficacy as well as high tumor mutation burden (TMB), which is determined using next-generation sequencing (NGS). However, a great deal of effort is required to perform NGS to determine TMB. Read More

Comprehensive Integrated Single-Cell Whole Transcriptome Analysis Revealed the p-EMT Tumor Cells-CAFs Communication in Oral Squamous Cell Carcinoma.

Int J Mol Sci 2022 Jun 9;23(12). Epub 2022 Jun 9.

Institute of Oral Medicine, College of Medicine, National Cheng Kung University, Tainan 701401, Taiwan.

Cancer-associated fibroblasts (CAFs) and partial epithelial-mesenchymal transition (p-EMT) tumor cells are closed together and contribute to the tumor progression of oral squamous cell carcinoma (OSCC). In the present study, we deeply analyzed and integrated OSCC single-cell RNA sequencing datasets to define OSCC CAFs and p-EMT subpopulations. We highlighted the cell-cell interaction network of CAFs and p-EMT tumor cells and suggested biomarkers for the diagnosis and prognosis of OSCC during the metastasis condition. Read More

Prognostic Role of Systemic Inflammatory Markers in Patients Undergoing Surgical Resection for Oral Squamous Cell Carcinoma.

Biomedicines 2022 May 29;10(6). Epub 2022 May 29.

Department of Hospital Pathology, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea.

Background: A high platelet-lymphocyte ratio (PLR) is a marker of systemic inflammation and, together with the neutrophil-lymphocyte ratio (NLR), is associated with poor outcomes in several cancers. We investigated the prognostic value of PLR and other systemic inflammatory markers, such as NLR, systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI), in oral squamous cell carcinoma (OSCC) patients undergoing surgical resection.

Methods: We derived PLR, NLR, SII, and SIRI from a retrospective chart review of 269 consecutive OSCC patients. Read More
