Nonsurgical Risk Factors Associated With Pharyngocutaneous Fistula in Patients Who Have Undergone Laryngectomy.

Importance: Pharyngocutaneous fistula (PCF) is a serious complication after total laryngectomy. Despite the well-described clinical risk factors for PCF and its association with poor quality of life, there is a paucity of data on the nonclinical factors that may be associated with this complication. Objective: To determine whether nonclinical risk factors (eg, age, sex, race and ethnicity) are associated with an increased risk of developing a PCF after total laryngectomy, and whether or not the method of reconstruction explains any differences found. Design, Setting, and Participants: This retrospective multicenter cohort study used data from a nationally validated, risk-adjusted, outcomes-based, surgical quality improvement database (the National Surgical Quality Improvement Program) to examine outcomes in patients who underwent a total laryngectomy from 2005 to 2018. The database was queried from January 1, 2005, to December 31, 2018; data analyses were performed from September 1, 2020, to March 31, 2021. Main Outcomes and Measures: The primary outcome was development of a PCF within 30 days of a total laryngectomy. Patient characteristics, including age, sex, race and ethnicity, comorbidities, and mode of reconstruction, were analyzed. Results: A cohort of 1573 adult patients (median age [IQR], 63 [56-71] years; 1280 [81.4%] men; 293 [18.6%] women; 1001 [63.6%] non-Hispanic White individuals) had undergone a total laryngectomy during the study period and were included in the analyses. The overall rate of PCF formation was 4.3% (68 of 1573 patients). Hispanic patients had the highest rate (9.5%; 9 of 95 patients) of PCF formation, which was more than twice the rate among non-Hispanic White patients (3.8%; 38 of 1001) and non-Hispanic Black patients (4.7%; 11 of 236). After adjusting for clinical and other covariates, women were 1.9 times more likely to develop a PCF compared with men (adjusted odds ratio, 1.90; 95% CI, 1.08-3.35). We also found that the odds of developing a PCF were 3-fold higher among Hispanic patients compared with non-Hispanic White patients (adjusted odds ratio, 2.96; 95% CI, 1.36-6.47). The type of reconstruction did not differ across age or race and ethnicity after controlling for clinical risk factors. Conclusions and Relevance: This multicenter cohort study found that 2 nonclinical risk factors-Hispanic ethnicity and female sex-were associated with an increased risk of PCF formation. Knowledge of these risk factors should be included in patient-physician decision-making as well as future interventions to decrease the rate of PCF formation after laryngectomy.

Long-term patient reported outcomes following radiation therapy for oropharyngeal cancer: cross-sectional assessment of a prospective symptom survey in patients ≥65 years old.

BACKGROUND: Given the potential for older patients to experience exaggerated toxicity and symptoms, this study was performed to characterize patient reported outcomes in older patients following definitive radiation therapy (RT) for oropharyngeal cancer (OPC). METHODS: Cancer-free head and neck cancer survivors (>6 months since treatment completion) were eligible for participation in a questionnaire-based study. Participants completed the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN). Those patients ≥65 years old at treatment for OPC with definitive RT were included. Individual and overall symptom severity and clinical variables were analyzed. RESULTS: Of the 79 participants analyzed, 82% were male, 95% white, 41% T3/4 disease, 39% RT alone, 27% induction chemotherapy, 52% concurrent, and 18% both, and 96% IMRT. Median age at RT was 71 yrs. (range: 65-85); median time from RT to MDASI-HN was 46 mos. (2/3 > 24 mos.). The top 5 MDASI-HN items rated most severe in terms of mean (±SD) ratings (0-10 scale) were dry mouth (3.48 ± 2.95), taste (2.81 ± 3.29), swallowing (2.59 ± 2.96), mucus in mouth/throat (2.04 ± 2.68), and choking (1.30 ± 2.38) reported at moderate-severe levels (≥5) by 35, 29, 29, 18, and 13%, respectively. Thirty-nine % reported none (0) or no more than mild (1-4) symptoms across all 22 MDASI-HN symptoms items, and 38% had at least one item rated as severe (≥7). Hierarchical cluster analysis resulted in 3 patient groups: 1) ~65% with ranging from none to moderate symptom burden, 2) ~35% with moderate-severe ratings for a subset of classically RT-related symptoms (e.g. dry mouth, mucus, swallowing) and 3) 2 pts. with severe ratings of most items. CONCLUSIONS: The overall long-term symptom burden seen in this older OPC cohort treated with modern standard therapy was largely favorable, yet a higher symptom group (~35%) with a distinct pattern of mostly local and classically RT-related symptoms was identified.
