Background: Cutaneous squamous cell carcinoma (cSCC) is characterized by a high tumor mutational burden due to solar damage and a favorable response to anti-PD-1 immunotherapy. Yet, we encounter tumors arising in areas with minimal sun exposure, such as cSCC that develops in chronically inflamed skin, also known as Marjolin's Ulcer (MU). The response of MU-SCC to immunotherapy remains unknown.

Until recently, however, lymphopenia was regarded as a minor sequela following radiation therapy (RT). The immune system's influence on rectal cancer treatment outcomes led us to evaluate the impact of lymphopenia at various time points, before, during, and following radiotherapy.

The IgG factor - cultured melanocyte elongation and proliferation - was found in the IgG fraction of the serum of BDUMP patients. It has been shown to be involved in melanocytic proliferation.

Importance: The emerging approach of neoadjuvant immunotherapy for solid cancers has set the ground for the integration of programmed cell death 1 (PD-1)/PD-1 ligand 1 (PD-L1) inhibitors into the neoadjuvant setting of head and neck squamous cell carcinoma (HNSCC) treatment.
Objective: To assess the reported efficacy and safety of neoadjuvant immunotherapy for resectable HNSCC.
Data Sources And Study Selection: Electronic databases, including PubMed (MEDLINE), Embase, the Cochrane Library, and ClinicalTrials.
Radioiodine-refractory thyroid cancers (IRTCs) are uncommon and have a poor prognosis. Treatment options for radioiodine-refractory and anaplastic tumors (ATCs) are limited. Although the genomic landscape of thyroid cancer has been studied, there is little evidence on whether next-generation sequencing (NGS) findings translate to tumor control.

The management of EPSCC is usually extrapolated from small-cell lung cancer (SCLC). In spite of the morphological similarity of the 2 malignancies, there are many differences in clinical features, prognosis, and recommendations of treatment of these disorders.

RRP has been known to be triggered by a number of chemotherapy agents. To the best of our knowledge, this report is the first description of RRP after administration of the Pfizer-BioNTech vaccine for COVID-19, or any other currently available vaccine against COVID-19.

Comprehensive risk stratification may pinpoint the most suitable adjuvant treatment. This study aimed to evaluate the outcomes of surgically treated locoregional CSCCHN and to identify prognostic indicators of treatment outcomes.

Purpose: Regionally metastatic cutaneous squamous cell carcinoma of the head and neck (CSCCHN) is usually managed surgically; however, the role of parotidectomy remains controversial. Herein we elucidate the controversy and present our experience.
Methods: We retrospectively analyzed disease variables, extent of parotidectomy, and pathologic characteristics in association to outcome measures of all advanced CSCCHN patients who underwent definitive surgical resection from 2008 to 2018.
Background: Salivary gland cancers (SGCs) are rare. The approach to metastatic patients is histology-dependent. There is little evidence on whether next-generation sequencing (NGS) findings translate to tumor control in SGCs.

In contrast to the well-documented effect of RAI on testicular function, the potential negative effects of this treatment on ovarian reserve have been largely dismissed. The objective of this pilot study was to examine the possibility that RAI treatment is deleterious to the ovarian reserve by prospectively measuring the concentration of anti-Müllerian hormone (AMH) after RAI treatment.

Objective: To systematically review the literature and carry out a meta-analysis of studies that compared elective neck dissection (END) with observation in patients with early-stage T1-T2 OTSCC and cN0 neck.
Data Sources: The MEDLINE, Scopus, Google scholar, and Cochrane databases were systematically searched for articles published between January 1, 1970, and June 1, 2015.
Background: Elective neck irradiation of a clinical node-negative (N0) neck in squamous cell carcinoma (SCC) of the maxillary sinus is a controversial issue.
Methods: A systematic review of electronic databases and a meta-analysis were conducted to clarify the role of elective neck irradiation in patients with SCC of the maxillary sinus and clinical N0 neck. Regional (neck) nodal recurrence was chosen as the primary endpoint.
Objective: Reduced mortality with low-dose computed tomography (LDCT) lung cancer screening was demonstrated in a large randomized controlled study of high-risk individuals. Cost-effectiveness must be assessed before routine LDCT screening is considered. We aimed to evaluate the cost-effectiveness of LDCT lung cancer screening in Israel.
View Article and Find Full Text PDFBackground: Management of head and neck carcinoma from unknown primary (HNCUP) remains controversial, with neck dissection and radiotherapy (RT) or definitive RT both commonly used. The purpose of this study was to characterize HNCUP and retrospectively compare outcomes for patients treated with neck dissection + RT versus definitive RT.
Methods: From 1994 to 2009, 41 patients with HNCUP underwent either neck dissection + RT (n = 22) or definitive RT ± concurrent chemotherapy (n = 19) at our institution.
Background: We investigated the risk of neck metastases in patients undergoing salvage total laryngectomy in association with previous radiotherapy.
Methods: The medical records of 42 patients (51 neck specimens) with clinical N0 classification who underwent salvage total laryngectomy in 2 cancer centers were reviewed. Fourteen patients had previous radiotherapy to the central neck and 28 to the central and lateral neck.

Purpose: To assess the risk of cervical lymph node metastases after definitive treatment for esthesioneuroblastoma (ENB) that did not include elective neck therapy.
Methods And Materials: This was a retrospective analysis of 26 ENB patients treated at the University of Michigan between 1995 and 2007. Tumor stage was Kadish A in 1 patient, B in 19, C in 5, and unknown in 1.

Purpose: To evaluate the impact of rotational setup errors on dose distribution in spinal stereotactic body radiotherapy (SBRT).
Methods And Materials: Thirty-nine cone beam computed tomography (CBCT) scans from 16 SBRT treatment courses were analyzed. Alignment (including rotation) to the treatment planning computed tomography was performed, followed by translational alignment that reproduced the actual positioning.

Elevated levels of SAA in the serum of cancer patients were suggested to be of liver origin rather than a tumor cell product. The role of SAA in human malignancies has not been elucidated.
