Radiation therapy is an important component in management of oral cancer. As a result, various uninvolved structures like salivary glands, oral , dentition, and jaws receive significant doses of radiation. Radiotherapy for oral cancer typically involves total doses of 6,000–7,000 , delivered in daily fractions over 6–7 weeks and is known to cause a number of oral complications. These include oral , oral pain, , increased risk of dental caries, reduced mouth opening, and . The aim of the study isto evaluate and identify the incidence rates of oral complaints following radiotherapy for oral cancer. Data samples required for study were taken from hospital records. All the collected data were cross verified and compiled together in sheet. Compiled data were statistically with help of SPSS software. In this study, a total of 51 patients of oral cancer underwent radiotherapy as a part of their treatment regimen. Higher percentage of patients reported back with no oral complaints of 58.82%. With an increase in age group, more patients had oral complaints after radiotherapy treatment, with p value of 0.114. More males had oral complaints compared to female patients with p value of 0.424. Within the limitations, it is significant that the maximum number of patients who underwent radiotherapy returned without any oral complaints.

Abstract The modeling and analysis of lifetime for terminal diseases such as cancer is a significant aspect of statistical work. This study considered data from thirty-seven women diagnosed with Ovarian Cancer and hospitalized for care at theDepartment of Obstetrics and Gynecology, University of Ibadan, Nigeria. Focus was on the application of a parametric mixture cure model that can handle skewness associated with survival data – a modified generalized-gamma mixture cure model (MGGMCM). The effectiveness of MGGMCM was compared with existing parametric mixture cure models using Akaike Information Criterion, median time-to-cure and variance of the cure rate. It was observed that the MGGMCM is an improved parametric model for the mixture cure model.

It is common knowledge that apparently similar tumors often show different responses to therapy. This experience has generated the idea that histologically similar tumors could have biologically distinct behaviour. The development of effective therapy therefore, has the explicit challenge of understanding biological behaviour of a tumor. The question is which parameters in a tumor could relate to its biological behaviour ? It is now recognised that the development of malignancy requires an alteration in the program of terminal differentiation in addition to aberrant growth control. In this study therefore, ultrastructural markers that relate to defective terminal differentiation and possibly invasive potential of cells have been identified in human oral leukoplakias, erythroleukoplakias and squamous cell carcinomas of the tongue.
