While radiotherapy, often in conjunction with chemotherapy, serves as a cornerstone in the management of locally advanced or metastatic cases, patient tolerance and treatment resistance frequently hinder its efficacy. Cell-in-cell structures, prevalent in various tumors, have been linked to prognosis. Hence, investigating the prognostic significance and regulatory mechanisms of genes related to these intracellular structures in esophageal cancer is imperative. The Cancer Genome Atlas (TCGA) Esophageal Cancer (ESCA) dataset served as the training set for the analysis. Differentially expressed genes (DEGs) in ESCA samples were identified, with those related to intercellular structures designated cell-in-cell-related differential expression genes (CIC-related DEGs). Cox regression analysis was employed to identify prognostic genes, categorizing samples into high- and low-risk groups based on median risk scores. Validation was conducted using the GSE53624 risk model. Established methodologies included morphological mapping, enrichment analysis, immune infiltration analysis, prognostic gene expression validation, molecular docking, and Reverse Transcription Polymerase Chain Reaction (RT-PCR) validation. Thirty-eight intersecting genes were identified between the disease and normal groups in ESCA samples. Stepwise multivariate Cox analysis pinpointed three prognostic genes: androgen receptor (AR), C-X-C motif chemokine ligand 8 (CXCL8), and epidermal growth factor receptor (EGFR). The risk model's applicability was confirmed in the GSE53624 dataset, revealing eight significantly different immune-related gene sets. Prognostic gene expression validation demonstrated significant differences between the disease and normal groups in both datasets. The proteins corresponding to the three prognostic genes interacted with gefitinib and osimertinib. RT-PCR results corroborated the differential expression of prognostic genes in esophageal cancer tissues.

Second, it explores potential vulnerable groups with respect to HRQL using decision tree analyses.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Women diagnosed with breast cancer who had paid work at diagnosis were recruited at 11 breast cancer centers in the Hannover region, Germany, after primary surgery. Assessments took place four times. 455 patients completed mailed questionnaires at 3 weeks after primary surgery. Women were followed up at 6 months, 1 year and on average 5 years after primary surgery. The physical and mental wellbeing dimensions of HRQL were examined through the Short-Form health survey-12. Potential associations between HRQL and health and sociodemographic factors were examined using multiple linear regression. Classification tree analyses were applied to define specific vulnerable groups.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Mastectomy (ß=-2.49; CI:-4.67, -0.30) and chemotherapy (ß=-4.25; CI:-7.04, -1.46) as health related factors were significantly associated with poorer physical wellbeing at 3 weeks and 6 months after primary surgery, respectively. Returning to work (RTW) after having been on sick leave was strongly associated with better HRQL as illustrated by higher sum scores for physical (at 3 weeks: ß=6.21; CI:3.36, 9.05; at 6 months: ß=5.40; CI:3.01, 1.80; at 1 year: ß=8.40; CI:5.31, 11.49) and mental wellbeing (at 6 months: ß=6.03; CI:33.25, 8.81; at 1 year: ß=7.71; CI:4.85, 10.58) until 1 year after primary surgery. However, its significant effect was no more apparent at 5 years after primary surgery. At that stage, income was mostly associated with physical (ß=0.002; CI:0.0002, 0.003) and mental wellbeing (ß=0.002; CI:0.0005, 0.003) with higher summary scores for higher income especially in women aged ≤ 61 years.
