Researchers at the University of Michigan are developing a model that uses predictive analytics to determine human survival and relapse outcomes for patients newly diagnosed with oropharyngeal cancer. Unlike previous grading systems that placed patients at broad risk groups, the predictive calculator uses predictive analytics to determine cancer recurrence or death by examining personality characteristics. 

 To quickly identify and diagnose OPSCC, researchers created a predictive calculator to predict survival outcomes by assessing individual characteristics and biomarkers. Researchers tested the model in a predictive study using a dataset that included 840 patients with newly diagnosed oropharyngeal cancer.  Patients were treated at a centre designated by the National Cancer Institute between January 2003 and August 2016. 

Using the findings, the researchers created a multi-state Bayesian model to create individualized projections of patient survival and relapse outcomes. The predictive efficacy of the model was confirmed by data from 447 patients treated for oropharyngeal cancer at the Erasmus Medical Center in the Netherlands. Predictive analysis determines the outcome of nasopharyngeal cancer. 

A retrospective review was conducted of 309 patients with recurrent laryngeal carcinoma, 224 of whom were treated between 1996 and 2009 at Sun Yatsen University Cancer Center, and 85 of them were treated between 2006 and 2013 at Zhejiang Cancer Hospital. Overall, these results suggest that the primary tumour is at stage T1 or T2, has a high rate of differentiation, no initial cervical lymph node metastases, a prolonged disease-free period, and an indication for rescue surgery. Are strong predictors for the patient. survival. with laryngeal relapse. epithelial cancer. 

The recurrence rate in patients with stage T1 laryngeal cancer ranges from 5% to 13%, and in patients with stage T2 cancer from 25% to 30%. For patients with stages T3 and T4, the relapse rate is 30-50%. Depending on the location of the tumour, laryngeal carcinoma can be divided into supralaryngeal carcinoma, carcinoma, or sublaryngeal carcinoma. Treatment options for recurrent carcinoma of the larynx are:  i) re-radiotherapy with or without chemotherapy, ii) rescue surgery, iii) supportive care, or iv) palliative chemotherapy. 

The previous study showed that, compared to a total laryngectomy, conservative surgery had a better prognosis, but it is possible that these results were due to selection bias, as in these high-grade patients than total laryngectomy. For patients undergoing surgery, a second or third surgery may also be the first choice as a definitive treatment.

If patients with recurrent tumours are not suitable for surgery or radiation therapy, the treatment is the same as for patients with metastases. The 5-year overall survival of patients with local recurrence undergoing life-saving surgery ranged widely from 22% to 66%. Previous research even showed that the 5-year survival rate in this group of patients was only 2%. It was performed on 309 patients with recurrent laryngeal carcinoma from two institutions who received the four above-mentioned treatments. 

 This study was performed to evaluate treatment outcomes in patients with recurrent laryngeal carcinoma and to identify prognostic factors that may affect survival to determine the management strategy and appropriate treatment for these patients. Patients with local recurrence had a 5-year survival rate of 61.8%, which was better than 52.1% in patients with regional recurrence and 0% in patients with distant metastases. 

 This is similar to the results of the aforementioned study by Brenner et al., In which 69% of local recurrent cases were saved with a 5-year survival rate of 76%; however, Lacy and Piccirillo reported that 64.5% of relapsed patients undergoing rescue surgery had a 2-year survival rate of only 55%. The reason this study had a higher survival rate maybe because there were more patients in the early stages. In a study by Yuen et al., Only 21% of patients with local recurrence underwent salvage surgery, and the 5-year tumour-free survival was only 42%. The reason so few patients met the criteria for salvage surgery in this study was that 97.9% of patients had primary T3 or T4 tumours and 100% of patients underwent total laryngectomy before recurrence. 

 Patients with a disease-free interval ≥of 12 months had a 5-year survival rate of 74.1%, which was significantly better than patients with a lot interval; 12 months. This univariate analysis showed that the following factors were negatively correlated with a 5-year overall survival rate: age ≥ 60 years, smoking index ≥ 600, poor tumour type, supraorbital and subglottic tumours, primary T3 and T4 T tumours, primary tumour. Stage III and IV UICC, active status of primary tumour lymph nodes, disease space and lt; 12 months, distant metastatic disease and tumour recurrence are not suitable for surgery. 

 Patients with poor baseline prognostic factors are more likely to receive surgery in combination with radiation therapy or chemotherapy with other treatments; The prognosis of tumour recurrence in these patients will be worse. Third, if radiation therapy was used to treat the primary tumour, re-irradiation of the recurrent tumour is not possible, and rescue surgery may also be impossible due to side effects, acute side effects of radiation, especially in patients with shorter recovery periods. 

 This is in contrast to Lacy and Piccirillo’s finding that smokers and nonsmokers had the same two-year survival rate of 40%. An exhaustive search in other relevant literature did not reveal any additional data on an association between smoking and recurrent laryngeal carcinoma; however, a study of secondhand smoke and the incidence of laryngeal cancer showed that patients with advanced tumours were mainly in the ecological smoking group. 

 These values ​​may explain why patients with recurrent tumours and smoking ≥600 have poor prognostic factors. A total of 122 patients had well-differentiated tumours, 138 patients with moderately differentiated tumours and 49 patients with moderately differentiated tumours.

Thus, the present study identified five predictors of good survival in patients with recurrent laryngeal cancer: stages T1 and T2 of the original tumour, high rate of differentiation, absence of metastases in the cervical lymph nodes of the original tumour, stage of the disease. It- Free for ≥12 months and meets the criteria for surgery. There are few predictive analytics applications in oncology, despite the need for more accurate predictions of life expectancy, intensive care, adverse events, and genetic and molecular risks. 

Despite the increasing amount of evidence combining clinical and use factors, powerful predictive tools are still needed to determine the risk of future acute use or other adverse outcomes. Predictive analytics tools automatically predict future health outcomes for individuals or populations based on algorithms derived from past patient data. ability to generalize. Predictive algorithms can identify patients at risk of death or in urgent care among patients receiving treatment.
