OPINION STATEMENT The 2016 revision of the WHO classification of lymphoid neoplasms includes new entities along with a clearer definition of provisional and definitive subtypes based on better understanding of the molecular drivers of lymphomas. These changes impact current treatment paradigms and provide a framework for future clinical trials. Additionally, this update recognizes several prema...

Photodynamic therapy (PDT) is used to treat localized premalignant or early malignant disease. This study reports the enhanced, systemic antitumor immune response from PDT, suggesting that it may have a potential role as a therapy to address both local and disseminated disease.

Here we discuss a recently published study from our group on how a continuous CD4 T-cell dependent immune clearance of premalignant senescent cells, designated "senescence surveillance," restricts liver cancer development.

Methods We obtained OCT images of normal, benign, premalignant and malignant lesions in different areas of the head and neck. The OCT imaging system has a tissue penetration depth of approximately 1-2mm, a scanning range of 2mm and a spatial depth resolution of approximately 10-20μm. Imaging was performed using a flexible probe in two different situations, the outpatient clinic and the operatin...

The paper included a review of the literature and some of my own research work dealing with the relationship between vitamin A and tumors. In animal experiments and in clinical investigations vitamin A and vitamin A acid had shown a preventive effect on the development of tumors as well as a therapeutic effect on certain established premalignant and malignant epithehal lesions. [The SC/B indica...

Bowens' disease (BD) is a precancerous condition of skin and/or mucosa with a predilection towards sun-exposed areas. Extensive literature research failed to reveal any case of multiple pigmented BD in type V Fitzpatrick skin. Multiple BD is a therapeutic challenge with a tendency to recur. Here we present an otherwise healthy Indian male having multiple pigmented lesions of BD on sun-protected...

OBJECTIVE The purpose of the study is to highlight the use of gamma-glutamyl transpeptidase (GGT) as salivary enzyme tumor marker and assess the activity and concentration of GGT in precancerous and cancer patients and compare it with the normal control. MATERIALS AND METHODS Individuals in the age group of above 20 years were included in the study. In this study, salivary GGT was analyzed in...

background: the present study was undertaken to estimate and compare the levels of plasma total cholesterol (tc), low density lipoprotein (ldl), high density lipoprotein (hdl), very low density lipoprotein (vldl) and triglycerides in patients with oral precancerous lesions/conditions, oral cancer and normal subjects. materials and methods: the study comprised of 60 patients with oral precancero...
