Utility of DNA-Specific Stains in Micronuclei Assay as a Marker of Genotoxicity in Oral Potentially Malignant Disorders and Oral Squamous Cell Carcinoma.

J Cytol 2019 Apr-Jun;36(2):111-115

Department of Oral Pathology, I.T.S-CDSR, Ghaziabad, Uttar Pradesh, India.

Background: The term oral potentially malignant disorder (OPMD) was recommended to refer to precancer as it conveys that not all disorders described under this term may transform into cancer. Oral squamous cell carcinoma (OSCC) arises through an accumulation of genetic alterations, deoxy ribonucleic acid (DNA) changes, and epigenetic alterations. Thus, a simple yet a sensitive and specific test for early diagnosis is the need of an hour. Read More

Cureus 2018 Dec 31;10(12):e3802. Epub 2018 Dec 31.

Oral Medicine and Radiology, Sathyabama Dental College and Hospital, Chennai, IND.

Oral squamous cell carcinoma is a leading cause of mortality due to late diagnosis in India and most other developing countries. Buccal squamous cell carcinoma is almost always preceded by premalignant conditions that include leukoplakia, erythroplakia, oral lichen planus, and submucous fibrosis of the oral cavity. Hence, these patients warrant regular screening by oral health care professionals and proper monitoring for any dysplastic changes. Read More

Such defects are complex as there is loss of outer skin, muscle, soft tissue, and inner mucosal lining. We report the use of submental artery island flap (SAIF) in the reconstruction of a large defect of oral commissure and buccal mucosa in a 70-year-old female with the diagnosis of verrucous carcinoma.

Comparison three-dimensional conformal radiotherapy versus intensity modulated radiation therapy in local control of head and neck cancer.

J Cancer Res Ther 2018 Oct-Dec;14(6):1412-1417

Department of Radiotherapy, Chirayu Medical College and Hospital, Bhopal, Madhya Pradesh, India.

Background: About 74% of head and neck cancer (HNC) patients need to undergo either definitive or postoperative radiation therapy because of aggressive nature of disease. The transition from two-dimensional conventional radiotherapy to three-dimensional conformal radiotherapy (3D-CRT) and further technological evolutions led to the successful clinical implementation of intensity modulated radiation therapy (IMRT), which constitutes an evolution of 3D-CRT. The IMRT technique gives the ability to create treatment fields with varying beam intensity using inverse planning and optimization algorithms to treat irregularly shaped target volumes with high precision.

Dose coverage comparison between "interstitial catheter-only" and "hybrid intracavitary-interstitial brachytherapy" for early stage squamous cell carcinoma of the buccal mucosa.

J Contemp Brachytherapy 2018 Oct 31;10(5):486-491. Epub 2018 Oct 31.

Department of Radiation Oncology, National Cancer Center Hospital, Chuo-ku, Tokyo, Japan.

Purpose: When squamous cell carcinoma of the buccal mucosa (BSCC) extends surrounding anatomical sites such as gingiva, retromolar triangle, or hard palate, it might be challenging to ensure adequate tumor coverage by sole interstitial brachytherapy due to the complexity of catheter implantation. By combining interstitial catheters with an enoral placed, individually assembled "oral spacer plus embedded catheters" device (hybrid of intracavitary-interstitial brachytherapy), it should be easier to deliver the necessary tumoricidal dose to irregular-shaped tumor volumes (clinical target volume - CTV) with improved conformity. The purpose of this analysis was to compare the dose distribution created by the hybrid of intracavitary-interstitial brachytherapy (HBT) with the dose distribution of an interstitial catheter only-approach, based on the interstitial catheters used for HBT (ISBT-only) by evaluating respective treatment plans (HBT plan vs. Read More

Determinants of level Ib involvement in oral squamous cell carcinoma and implications for submandibular gland-sparing neck dissection.

Int J Oral Maxillofac Surg 2018 Dec 29;47(12):1507-1510. Epub 2018 Jun 29.

Department of Head and Neck Oncology, Amrita Institute of Medical Sciences, Amrita Vishwa Vidyapeetham, Kochi, Kerala, India.

Traditional neck dissection for oral squamous cell carcinoma (OSCC) involves removal of the submandibular salivary gland. Several studies have cited the low incidence of direct gland invasion by tumours and have recommended gland-sparing neck dissection. In this study, a detailed audit of level Ib involvement in OSCC was performed in order to assess the feasibility of submandibular gland-sparing in neck dissection; the rate of direct involvement by the primary tumours, the involvement of periglandular level Ib nodes, and their determinants were investigated.

PEGylated liposome-encapsulated rhenium-188 radiopharmaceutical inhibits proliferation and epithelial-mesenchymal transition of human head and neck cancer cells in vivo with repeated therapy.

Cell Death Discov 2018 31;4:100. Epub 2018 Oct 31.

1Department of Biomedical Imaging and Radiological Sciences, National Yang-Ming University, Taipei, Taiwan.

Human head and neck squamous cell carcinoma (HNSCC) is usually treated with chemoradiotherapy, but the therapeutic efficacy could be hampered by intrinsic radioresistance and early relapse. Repeated administrations of rhenium-188 (Re)-conjugated radiopharmaceutical has been reported to escalate the radiation doses for better control of advanced human cancers. Here we found that high dosage of Re-liposome, the liposome-encapsulated Re nanoparticles exhibited significant killing effects on HNSCC FaDu cells and SAS cells but not on OECM-1 cells. Read More
