Orbital Exenteration: Tumour Diversity and Survival-Report from a Cancer Centre of Northeast India.

Orbital exenteration is a mutilating surgery which involves the removal of the entire contents of the bony orbit, including the globe, extraocular muscles and periorbital fat, and many times includes the eyelids. Since it leads to severe disfigurement, it is an infrequent procedure largely indicated in malignant conditions. The current study aims to report the clinicodemographic profile and treatment outcome of orbital exenteration patients done in a cancer care center in Northeast India.

Giant dermatofibrosarcoma protuberans head and neck: a diagnostic dilemma.

DFSP primarily occurs on the trunk and proximal extremities, with reported only 10-15% occurring in the head and neck region. There can be varied presentations of DFSP in atypical sites mimicking a benign appearance and history due to which diagnostic dilemmas can occur.

Submandibular Gland in Neck Dissection: Necessary Fatality or Unfortunate Prey?

Stain color translation of multi-domain OSCC histopathology images using attention gated cGAN.

Oral Squamous Cell Carcinoma (OSCC) is the most prevalent type of oral cancer across the globe. Histopathology examination is the gold standard for OSCC examination, where stained histopathology slides help in studying and analyzing the cell structures under a microscope to determine the stages and grading of OSCC. One of the staining methods popularly known as H&E staining is used to produce differential coloration, highlight key tissue features, and improve contrast, which makes cell analysis easier.

Pattern of Nodal Metastasis in Relation to Size of the Primary Tumour in Well-Differentiated Thyroid Carcinoma.

This study was conducted to see the pattern of neck node metastasis in relation to the size of primary tumour in Well-differentiated thyroid cancer. A prospective study on 50 patients was carried out in the Department of Head and Neck Surgery, Dr B. Borooah Cancer Institute from 1st August, 2018 to 31st July, 2019.

Dysbiosis of salivary microbiome and cytokines influence oral squamous cell carcinoma through inflammation.

Advanced combinatorial treatments of surgery, chemotherapy, and radiotherapy do not have any effect on the enhancement of a 5-year survival rate of oral squamous cell carcinoma (OSCC). The discovery of early diagnostic non-invasive biomarkers is required to improve the survival rate of OSCC patients. Recently, it has been reported that oral microbiome has a significant contribution to the development of OSCC.

Alterations of salivary microbial community associated with oropharyngeal and hypopharyngeal squamous cell carcinoma patients.

The highest number (35.1% of global incident cases) of new oropharyngeal (OP) and hypopharyngeal (HP) cancer cases was reported in South-Central Asia. The highest incidence of HP cancer in India was reported in East Khasi Hills District of Meghalaya, Aizawl District of Mizoram, and Kamrup Urban District of Assam.

Redo Tracheostomy: Our Experience, Problems Encountered and How to Overcome Them.

Tracheostomy is a life-saving procedure done electively or most commonly in emergency basis. In patients with diagnosed case of cancer in upper airway tract they usually require tracheostomy at some point of time during their whole treatment procedure. Patients receiving radiotherapy or chemotherapy or combination of these are at high risk of developing post treatment changes in neck anatomy.
