The aim of this study was to see whether serial cytological evaluation of various cellular abnormalities in tumours from patients receiving fractionated radiotherapy can predict radio-response in oral carcinoma. Cytological assessment was carried out in scrape smears collected prior to and during the course of radiotherapy in 68 patients with squamous cell carcinoma of the oral cavity planned for radical radiotherapy with accelerated fraction schedule. Smears were evaluated for a set of 15 radiation-induced cellular abnormalities. The relationship between the cellular alterations and the cumulative radiation dose was analysed by Kruskal-Wallis one-way anova. The results showed that among the various quantifiable changes that occur in irradiated cancer cells, karyolysis, karyorrhexis, pyknosis, cytolysis, multinucleation, micronucleation and nuclear budding show significant increase depending on the dose of radiation. The radio-resistant group of patients exhibited a lesser degree of change compared with the radio-sensitive group. This suggests that radio-resistance may be due to the defective induction of cell damage and that these cytological features may have potential use as predictive markers of radio-sensitivity in oral carcinoma.
BACKGROUND
Microvascular surgery is a highly technique sensitive and evolving speciality in reconstructive oncosurgery. There is a definite learning curve associated with it. In this case series, we describe our initial experience in microvascular surgery at a tertiary cancer centre in North East India.
METHODS
It is a retrospective observational case series done at a tertiary cancer centre in North East India from May 2018 to Jul 2018. The first ten cases of our free flap journey till now were included in the study. Data were collected from patient records and the hospital online reporting system. All data were analysed using SPSS.
RESULTS
In our series, 8 patients were male and 2 patients were female. The mean age in the series was 37 years. Squamous cell carcinoma accounts for 4 the patients, osteosarcoma for 2 of patients and adenoid cystic carcinoma, Ewing sarcoma, rhabdomyosarcoma and low-grade soft tissue sarcoma 1 case each. Out of the ten free tissue transfers, one free ALT flap for total maxillary defect failed during the 4th postoperative day and the patient was managed with a prosthesis. The average hospital stay during the case series was 10.6 days.
CONCLUSION
Microvascular surgeries are very complex surgeries. The presence of a good, well-trained plastic surgery team working in conjunction with other specialities is paramount for a good outcome. A dedicated team, cooperative administration, fine and good infrastructure with high-quality equipment are the basic necessities for creating a good microsurgery unit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
