Sugemalimab is a full-length, fully human PD-L1 targeted immunoglobin G4 (IgG4, s228p) mAb. GEMSTONE-302 randomized, double-blind, phase 3 study to evaluate the efficacy and safety of sugemalimab or placebo in combination with chemotherapy as first-line treatment metastatic squamous (sq) non-squamous (nsq) NSCLC. The PFS interim analysis data 08 June 2020 showed that plus demonstrated clinicall...

OBJECTIVE To investigate correlations among A-kinase anchor protein95 (AKAP95), Connexin43 (Cx43), CyclinE1 and CyclinD1 in esophageal squamous cell cancer tissues, and their relationship with clinical and pathological parameters. METHODS The protein levels of AKAP95, Cx43, CyclinE1 and CyclinD1 in 54 cases of esophageal squamous cell cancer tissues were determined by immunohistochemistry. ...

ABSTRACT Squamous metaplasia of the rete ovarii is an ovarian pathologic change characterized by replacement normal single layered cuboidal epithelium a stratified squamous keratinized epithelium. Uterus and ovaries from local slaughterhouse pregnant crossbreed cow were evaluated through ultrasound, macroscopically histologically. Grossly, there multiple cysts in both ovaries, which histologica...

The squamous odontogenic tumour is a rare benign neoplasm whose aetiology remains unknown. It usually appears in the jaw and its origin could be related to the ephitelial remnants of Malassez. Histologically comprises numerous islets of squamous, non-keratinized, well-differentiated and rounded epithelial cells a fibrous stroma without signs of atypical cells. There is a non-neoplastic lesion w...

AIM To characterize the immunohistochemical expression of p27, p21(WAF/Cip1) and p16(INK4a) in normal oral epithelium, oral squamous papilloma and oral squamous cell carcinoma. MATERIALS AND METHODS Immunohistochemical staining for p27, p21(WAF/Cip1) and p16(INK4a) was evaluated in 32 samples of normal oral squamous epithelium, 30 samples of oral squamous papilloma, and 34 samples of oral squ...

Introduction. Collision tumor of the thyroid gland is defined when independent and histologically distinct tumors coexist within the gland. The presence of both papillary and squamous cell carcinoma in the thyroid gland is unusual. Suggested etiologies include embryonic remanents of squamous epithelium, chronic inflammation, or thyroid malignancies promoting squamous metaplasia. Case Presentati...

Background: Oral squamous cell carcinoma is a major cause of cancer-related deaths world-wide. Histologically it arises from the benign squamous epithelium lining the oral cavity and is conventionally divided into well, moderate, and poorly differentiated subtypes. Nicotinamide phosphoribosyltransferase catalyses the rate-limiting step of nicotinamide adenine dinucleotide synthesis and is highl...

Histologic changes suggesting HPV infection are occasionally found adjacent to squamous cell carcinoma or in squamous papilloma of the esophagus, but the relationship between HPV infection and benign and malignant squamous lesions of the esophagus is not yet dear. The aim of this study was to examine the role of HPV in squamous lesions of the esophagus. Microscopic examination with emphasis on ...

Management of patients with metastatic squamous cell skin cancer, refractory to initial therapy with standard chemotherapy and radiation protocols, remains difficult with poor overall prognosis and limited therapeutic options. Recently, promising response rates with nivolumab, a programmed death receptor-1-blocking antibody, in squamous cancer of the head and neck have been demonstrated. Consid...

PURPOSE Treatment results evaluation (radical cystectomy and adjuvant chemo/radiotherapy) in patients with urothelial carcinoma, squamous differentiation carcinoma and pure squamous bladder carcinoma. MATERIAL AND METHODS The study included 361 patients with invasive bladder carcinoma treated between 1990-2013. Histology showed 296 cases of urothelial carcinoma (82% - group A), 52 cases of ur...
