Survey of long term survivors of oral cancer: Looking beyond cancer biology.

6087 Background: While surgery is the main stay of treatment for early stage oral cancers, advanced stages require adjuvant treatments in the form of radiotherapy or concurrent radiotherapy. Yet, the effectiveness of these interventions is not solely determined by clinical measures but also by personal factors such as individual motivation, support from loved ones, and financial security. These aspects might explain the survival rate variations among patients who, despite having similar prognostic categories and stages of disease, show differing outcomes. The role of social determinants in influencing patient survival, apart from the acknowledged impact of disease biology, is not well understood. Methods: All treatment-naive oral cavity cancer patients who underwent definitive treatment during 2014 to 2018 at our institute and are alive for more than five years were selected for this study. A custom investigator-administered questionnaire was developed and it had 32 questions under six domains- personal, habit history, financial, social, functional, and emotional. The study was approved by the institutional ethics committee. Of the 1787 potential participants, we found that 219 had expired, only 442 patients agreed to answer the questionnaire, while 45 refused to participate. The rest of the patients were not reachable telephonically. Results: This survey had 442 patients, of which 90% were males, with a mean age of 52.1 years. The most common site of the presentation was buccal mucosa (60%), and 59% presented in the locally advanced stage. Post-operatively, 71% received adjuvant therapy. All patients were motivated to undergo the radical treatments and had their family support. However, post-treatment, about 10% of individuals experienced a change in marital status. Financial constraints did affect 20% of patients during and after treatment, and more than 70% had their out-of-pocket expenditure above 50% of the total cost. While 80% did not have trouble attending social functions, 46% reported trouble eating socially. However, this was more common for patients who received adjuvant treatment (p < 0.001). About 21% reported shoulder dysfunction and body discomfort. However, no statistically significant associations could be drawn for any of the domains of the questionnaire when compared to patients between the early and late stages. Shoulder discomfort was experienced more by patients who were treated for tongue cancer (p-value 0.010). Conclusions: The results of this study shed light on the challenges faced by long-term survivors of oral cancer following radical treatment regimens. More than half of patients reported that out-of-pocket expenses constituted more than half of their total treatment costs. A notable minority of people suffer from shoulder dysfunction, suggesting there is a clear opportunity for advancements in reconstruction and rehabilitation.
