Development of a nomogram for predicting pharyngocutaneous fistula based on skeletal muscle mass and systemic inflammation indices. Head Neck 2024; 46:571-580. [PMID: 38124665 DOI: 10.1002/hed.27614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 11/16/2023] [Accepted: 12/12/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Laryngeal and hypopharyngeal cancers often require surgical treatment, which can lead to the development of pharyngocutaneous fistula (PCF). Our research aimed to assess the predictive value of skeletal muscle mass (SMM) and systemic inflammation indices for PCF and construct a clinically effective nomogram. METHODS A nested case-control study of 244 patients matched from 1171 patients with laryngeal or hypopharyngeal cancer was conducted. SMM was measured at the third cervical level based on CT scans. A PCF nomogram was developed based on the univariate and multivariate analyses. RESULTS Glucose, white blood cell count, platelet-to-lymphocyte ratio, and skeletal muscle index were independent risk factors for PCF. The area under the curve for the PCF nomogram was 0.841 (95% CI 0.786-0.897). The calibration and decision curves indicated that the nomogram was well-calibrated with good clinical utility. CONCLUSIONS The nomogram we constructed may help clinicians predict PCF risk early in the postoperative period, pending external validation.

Abstract
OBJECTIVES Despite the increasingly modern surgical techniques in the oncology field, the factors that influence postoperative prognosis in patients with hypopharyngeal and laryngeal carcinoma (HLC) remain unclear. The study aimed to evaluate the factors influencing the prognosis of HLC patients with pathological diagnosis of squamous cell carcinoma, and the findings are intended to direct follow-up management strategies. METHODS A retrospective cohort study was performed. The study population included 407 postoperative patients with HLC from 2011 to 2015. Univariate and multivariate analyses were used to examine the prognostic factors identified. RESULTS Based on univariate analysis results, smoking and alcohol history, tumor differentiation, preoperative radiotherapy, primary tumor sites, flap reconstruction, lymph node invasion (LNI), and preoperative albumin levels (PAL) significantly affects the prognosis of HLC patients (P < .05). Meanwhile, multivariate analysis revealed that smoking pack-year (OR = 1.002, 95% CI = 1.001 ∼ 1.003), primary tumor sites (OR = 6.241, 95% CI = 1.715 ∼ 18.433), LNI (OR = 2.869, 95% CI = 1.095 ∼ 8.743), and PAL (OR = .020, 95% CI = .004 ∼ 0.104) were associated with complications. Tumor differentiation (OR = 0.650, 95% CI = .383 ∼ 0.855), primary tumor sites (OR = 12.392, 95% CI = 3.290 ∼ 26.679), LNI (OR = 16.323, 95% CI = 2.726 ∼ 47.729), preoperative radiotherapy (OR = 9.300, 95% CI = 3.182 ∼ 27.181), and PAL (OR = .321, 95% CI = .141 ∼ .732) were associated with overall survival rates. CONCLUSION Smoking and alcohol history, tumor differentiation, LNI, primary tumor sites, flap reconstruction, PAL, and preoperative radiotherapy are crucial factors that influence the postoperative prognosis of patients with HLC. In addition, a monogram of five factors was established to predict the survival rates of HLC patients.

Risk factors for adverse events associated with endoscopic submucosal dissection for superficial pharyngeal cancer. Surg Endosc 2023; 37:6322-6332. [PMID: 37202526 DOI: 10.1007/s00464-023-10118-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Accepted: 05/08/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND Superficial pharyngeal cancer can be treated with curative intent while preserving function using minimally invasive peroral endoscopic resection techniques such as endoscopic submucosal dissection (ESD). However, severe adverse events occasionally occur, such as laryngeal edema requiring temporary tracheotomy and fistula formation. Therefore, we investigated the risk factors for adverse events associated with ESD for superficial pharyngeal cancer. METHODS This retrospective observational study was conducted at a single institution, and 63 patients who underwent ESD were enrolled. The primary outcome was the risk factors for adverse events associated with ESD. The secondary outcomes were adverse events associated with ESD and their frequency. RESULTS The overall adverse event rate was 15.9% (10/63). The incidence of laryngeal edema requiring prophylactic temporary tracheotomy was 11.1%, while laryngeal edema requiring emergency temporary tracheotomy, postoperative bleeding, aspiration pneumonia, fistula, abscess, and stricture formation occurred in 1.6% of patients, respectively. Logistic regression analyses showed that a history of radiotherapy for head and neck cancer was a risk factor for adverse events (odds ratio [OR], 16.67; 95% confidence interval [CI], 3.04-91.34; p = 0.001). After adjusting the model for differences in the baseline risk factors using the inverse probability of treatment weighting method, the adverse events were found to increase in association with a history of radiotherapy for head and neck cancer (OR, 39.66; 95% CI,5.85-268.72; p < 0.001). CONCLUSION History of radiotherapy for head and neck cancer is an independent risk factor for adverse events associated with ESD for superficial pharyngeal cancer. Among adverse events, laryngeal edema requiring prophylactic temporary tracheotomy was particularly high.

Factors predicting pharyngocutaneous fistula in patients after salvage laryngectomy for laryngeal malignancy - A multicenter collaborative cohort study. Oral Oncol 2022; 134:106089. [PMID: 36057225 PMCID: PMC10190204 DOI: 10.1016/j.oraloncology.2022.106089] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 08/10/2022] [Accepted: 08/15/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVES Pharyngocutaneous fistula (PCF) is a major morbidity of salvage total laryngectomy (TL). Understanding the factors predicting PCF is fundamental to managing laryngeal cancer. We aim to assess factors associated with PCF following salvage TL in a multicenter, international retrospective cohort study of academic centers in the US and Canada. RESULTS In total, 550 patients post-salvage TL were identified (mean [SD; range] age, 64 [10.4; 32-90] years; 465 [85 %] male and 84 [15 %] female) between 2000 and 2014. Rate of PCF was 23 % (n = 127) with median time to PCF of 2.9 weeks. Surgical management of PCF was required in 43 % (n = 54) while 57 % (n = 73) required wound care alone. Rates of PCF differed by primary treatment modality [radiation, 20 % (n = 76); chemoradiation, 27 % (n = 40); not available (n = 6)] and use of vascularized tissue in pharyngeal closure [free/regional flap, 18 % (n = 25); no vascularized tissue/primary closure, 24 % (n = 98); not available (n = 4)]. There was no statistically significant association between PCF and treatment with chemoradiation (HR, 1.32; 95 % CI, 0.91-1.93, p = 0.14) or lack of vascularized tissue reconstruction (HR, 1.41, 95 % CI 0.91-2.18, p = 0.12). Significant association between PCF and advanced stage (T3 or T4), positive margin, close margin (<5mm), lymphovascular invasion and pre-operative tracheostomy were identified on univariable analysis. Positive surgical margin (HR, 1.91; 95 % CI, 1.11 to 3.29) was the only significant association on multivariable analysis. CONCLUSION We highlight positive surgical margin as the only variable significantly associated with increased risk of PCF following salvage TL on multivariable analysis in a large cohort across several major head and neck oncology centers.

Pharyngocutaneous Fistula Following Primary and Salvage Laryngectomy: Aetiology and Predictive Factors. Indian J Otolaryngol Head Neck Surg 2022; 74:2139-2148. [PMID: 36452720 PMCID: PMC9701951 DOI: 10.1007/s12070-020-02046-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 08/08/2020] [Indexed: 10/23/2022] Open
Abstract
Laryngeal cancer treatment is often wrought with challenges, pharyngocutaneous fistula formation (PCF) in patients undergoing either primary or salvage laryngectomy for laryngeal and hypopharyngeal for squamous cell carcinoma is an important one. We aimed to study the factors before and at the surgery that are associated with PCF formation in a South Indian tertiary care hospital. A retrospective chart review of 127 patients who underwent total laryngectomy (TL) between May 2014 and April 2019 at our centre were done. Data was collected, including patient age and gender, comorbidities (Diabetes mellitus, COPD and hypothyroidism), smoking, tumor stage and site, prior tracheostomy, prior radiation, concurrent neck dissection and type of pharyngoplasty, Preoperative hemoglobin and albumin levels, surgical margin status and development of a PCF was also done. Further details specific to the development of a PCF were recorded for that subset of patients including the length of time to fistula, mode of closure, time of closure and modality of management. The overall incidence of PCF was 16.5% (21 of 127 patients), and the median time from TL to the diagnosis of PCF was 6 days (range, 3-20 days). The analysis was done separately for laryngectomies without any pharyngeal reconstruction (112/127 patients). In patients treated with a primary TL, the incidence of PCF was 12.20% (10 of 82) and 26.66% (8 of 30) after salvage TL. Subset analysis for type of pharyngoplasty repair showed 12% (15/127) underwent different types of vascularised/muscular flap for smaller residual pharyngeal mucosa, of which 20% (3/15) developed PCF and one patient developed haematoma needing exploration and re-suturing. The predictive factors for PCF were hypopharynx cancer (P < 0.05), surgical margin positivity (P < 0.0001), female gender (P < 0.05), absence of prior tracheostomy (P < 0.05) and tumor extension into pyriform sinus mucosa (P < 0.05). Preoperative patient factors of gender and site of primary along with histological margin positivity and extension of tumor to the pyriform sinus mucosa were significant risk factors for PCF formation. Pre-Op radiotherapy remains a strong clinical suspicion but not statistically significant.

A practical guide for perioperative smoking cessation. J Anesth 2022; 36:583-605. [PMID: 35913572 DOI: 10.1007/s00540-022-03080-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Accepted: 05/24/2022] [Indexed: 12/15/2022]
Abstract
The perioperative management of patients who are smokers presents anesthesiologists with various challenges related to respiratory, circulatory, and other clinical problems. Regarding 30-day postoperative outcomes, smokers have higher risks of mortality and complications than non-smokers, including death, pneumonia, unplanned tracheal intubation, mechanical ventilation, cardiac arrest, myocardial infarction, and stroke. Given the benefits of smoking cessation and the adverse effects of smoking on perioperative patient management, patients should quit smoking long before surgery. However, anesthesiologists cannot address these issues alone. The Japanese Society of Anesthesiologists established guidelines in 2015 (published in a medical journal in 2017) to enlighten surgical staff members and patients regarding perioperative tobacco cessation. The primary objective of perioperative smoking cessation is to reduce the risks of adverse cardiovascular and respiratory events, wound infection, and other perioperative complications. Perioperative preparations constitute a powerful teachable moment, a "golden opportunity" for smoking cessation to achieve improved primary disease outcomes and prevent the occurrence of tobacco-related conditions. This review updates the aforementioned guidelines as a practical guide to cover the nuts and bolts of perioperative smoking cessation. Its goal is to assist surgeons, anesthesiologists, and other medical professionals and to increase patients' awareness of smoking risks before elective surgery.

Abstract
Objectives Pharyngocutaneous fistula (PCF) is a troublesome complication after total laryngectomy. The “Fistula zero” project aims to reduce the number of PCF by following a detailed protocol based on three fundamental key points. Materials and Methods The Fistula zero project included 77 patients who underwent total laryngectomy in the period from January 2019 to December 2020. The protocol consisted of three main aspects: the systematic placement of a Har-El salivary bypass tube, the continuous horizontal watertight pharyngeal suture using a barbed suture, onlay insetting of a pedicled flap in pre-treated patients. Results One case of PCF (1.3%) and three small blind fistulas (3.9%) were observed in this series. The mean length of hospitalization was 18 days. Conclusion Pharyngocutaneous fistula (PCF) prolongs hospitalization and delays adjuvant treatments. Thanks to a strict adherence to the protocol, it was possible to reduce PCF rates, avoiding lengthy hospitalization and additional surgical procedures.

Prediction of risk factors for pharyngo-cutaneous fistula after total laryngectomy using artificial intelligence. Oral Oncol 2021; 119:105357. [PMID: 34044316 DOI: 10.1016/j.oraloncology.2021.105357] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 05/16/2021] [Accepted: 05/17/2021] [Indexed: 01/17/2023]
Abstract
OBJECTIVES Pharyngocutaneous fistula (PCF) is one of the major complications following total laryngectomy (TL). Previous studies about PCF risk factors showed inconsistent results, and artificial intelligence (AI) has not been used. We identified the clinical risk factors for PCF using multiple AI models. MATERIALS & METHODS Patients who received TL in the authors' institution during the last 20 years were enrolled (N = 313) in this study. They consisted of no PCF (n = 247) and PCF groups (n = 66). We compared 29 clinical variables between the two groups and performed logistic regression and AI analysis including random forest, gradient boosting, and neural network to predict PCF after TL. RESULTS The best prediction performance for AI was achieved when age, smoking, body mass index, hypertension, chronic kidney disease, hemoglobin level, operation time, transfusion, nodal staging, surgical margin, extent of neck dissection, type of flap reconstruction, hematoma after TL, and concurrent chemoradiation were included in the analysis. Among logistic regression and AI models, the neural network showed the highest area under the curve (0.667 ± 0.332). CONCLUSION Diverse clinical factors were identified as PCF risk factors using AI models and the neural network demonstrated highest predictive power. This first study about prediction of PCF using AI could be used to select high risk patients for PCF when performing TL.

Functional Outcomes and Complications After Salvage Total Laryngectomy for Residual, Recurrent, and Second Primary Squamous Cell Carcinoma of the Larynx and Hypopharynx: A Multicenter Retrospective Cohort Study. Front Oncol 2020; 10:1390. [PMID: 32983968 PMCID: PMC7492266 DOI: 10.3389/fonc.2020.01390] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Accepted: 07/01/2020] [Indexed: 11/25/2022] Open
Abstract
Background/Purpose: We analyzed complications and functional outcomes and aimed at identifying prognostic factors for functional outcomes and complications in patients who underwent salvage total laryngectomy (STL) for residual, recurrent, and second primary squamous cell carcinoma (SCC) of the larynx and hypopharynx after initial (chemo)radiation. Methods: Retrospective cohort study of patients who underwent STL in four major Belgian reference hospitals between 2002 and 2018. Prognostic factors for functional outcomes and complications were identified with uni- and multivariable analysis. Results: A total of 405 patients were included in the final analysis. STL was performed for residual tumor (40.2%), local recurrence (40.5%), or second primary laryngeal or hypopharyngeal SCC (19.4%). Early postoperative complications were experienced by 34.2% of patients: postoperative hemorrhage occurred in 5.4%, wound infection in 16.2%, and clinical pharyngocutaneous fistula (PCF) in 25.5% of patients. Early readmission proved necessary in 15.1% of cases, most often due to late PCF development (72.2%). Patients achieved total peroral intake in 94.2% of cases. However, subjective dysphagia was reported by 31.3% of patients during follow-up. Functional speech, defined as functional communication by speech without additional aids, was reported in 86.7% of cases and was most often achieved by tracheo-esophageal puncture (TEP) (94.1%). In a multivariable model, lower preoperative hemoglobin (<12.5 g/dl) was identified as an independent prognostic factor for higher overall complication rate. No risk factors were found significant for clinical fistula formation. Vascularized tissue augmentation did not significantly prevent clinical PCF. Patients with positive section margins, patients initially treated with surgery combined with adjuvant RT (vs. radiotherapy alone), and those developing PCF after STL were less likely to achieve total peroral intake. Postoperative dysphagia proved more likely in patients who developed a PCF postoperatively, and less likely in patients who underwent STL without partial pharyngectomy and in patients with myocutaneous pectoralis major (PM) flap reconstruction, compared to muscle onlay PM flap. Achieving postoperative functional speech proved most likely in patients with smaller tumors (lower pT classification) and free section margins. Conclusion: Substantial complication rates and favorable functional outcomes are reported after STL.

Long-term outcomes of trans-oral robotic surgery-assisted total laryngectomy for recurrent laryngeal cancers. Jpn J Clin Oncol 2020; 50:653-660. [PMID: 32236415 DOI: 10.1093/jjco/hyaa034] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 02/22/2020] [Accepted: 02/29/2020] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE For recurrent laryngeal cancers, trans-oral robotic surgery has been used to perform total laryngectomy, but limited cases had been reported without long-term outcome follow-up. This study aims at presenting the largest longitudinal retrospective cohort in a single tertiary referral medical center. METHODS From November 2013 to August 2017, seven patients with recurrent laryngeal cancers without evidence of neck metastasis were selected to receive trans-oral robotic surgery-assisted TL without neck dissection. The para-operative details including the surgical success rates, surgical methods, resection extent, drainage tube placement, pharyngeal wound closure, console surgical time, pathologic findings and long-term complications were reviewed and described. The study end points include survival rates and preservation of swallowing function without tube feeding. RESULTS Trans-oral robotic surgery-assisted total laryngectomy was successfully performed on all seven patients with mean surgical console time of 111 ± 66 min. Strap muscles and hyoid bone were resected like open surgery in six and five patients, respectively. For all the seven patients, there was no severe pharyngo-cutaneous fistula formation requiring repair in a second surgery, but tracheostoma stenosis was not uncommon (57%). Three patients received adjuvant chemotherapy/radiotherapy. After follow-up of 36.1 ± 15.8 months, two patients had neck recurrence, and one patient died 19 months after surgery, but the other five patients were alive without disease recurrence. The overall survival rate was 85.7% (6/7), and all patients had good swallowing function without tube feeding. CONCLUSIONS Trans-oral robotic surgery-assisted total laryngectomy is a feasible approach for selected patients with recurrent laryngeal cancers. The oncologic and functional outcomes were satisfactory. Further larger cohort study is worthwhile to further elucidate the value of trans-oral robotic surgery-assisted total laryngectomy.

Abstract
BACKGROUND Little is known about what factors affect patient-reported swallowing outcome after total laryngectomy. We explored whether patient demographics, surgical variables, use of adjuvant treatment, and time since surgery were associated with patient-reported swallowing outcome. METHODS Cross-sectional study of laryngectomees in eight UK hospitals. Demographic, treatment, and surgical variables were drawn from medical notes. The swallowing outcomes after laryngectomy (SOAL) questionnaire captured perceived swallowing outcome. RESULTS Two hundred and twenty one participants had complete data on treatment-related variables. In regression analysis, having a free jejunum flap repair and requiring chemoradiation were the only two variables that added significantly to the model of worse self-reported swallowing outcome (R2 adjusted = .23, P < .001). CONCLUSION The SOAL is a sensitive measure of self-reported swallowing outcome after laryngectomy. Type of surgical closure and the type of additional treatment influenced the swallowing outcome reported by patients. Changes in perceived swallowing function need to be routinely evaluated to inform clinical decision-making and intervention.

Abstract
OBJECTIVE The purpose of this study was to systematically evaluate the risk factors of pharyngocutaneous fistula (PCF) after total laryngectomy. METHODS We systematically searched Pubmed, Web of Science, Cochrane Library, and Embase databases and included the literature according to the inclusion and exclusion criteria. RESULTS A total of 52 studies with 8605 patients were included in the meta-analysis. The total incidence of PCF was 21% (1808/8605). Meta-analysis results indicated that age (OR = 1.29, 95% CI 1.06-1.58, P = 0.01), smoking (OR = 1.62, 95% CI 1.27-2.07, P < 0.01), COPD (chronic obstructive pulmonary disease) (OR = 1.62, 95% CI 1.19-2.22, P < 0.01), CAD (coronary atherosclerotic heart disease) (OR = 1.82, 95% CI 1.36-2.45, P < 0.01), T-stage (OR = 0.81, 95% CI 0.67-0.98, P = 0.03), previous radiotherapy (OR = 2.41, 95% CI 2.00-2.90, P < 0.01), preoperative albumin (OR = 2.95, 95% CI 1.47-5.91, P < 0.01), preoperative hemoglobin (OR = 1.97, 95% CI 1.28-3.03, P < 0.01), tumor site (OR = 0.28, 95% CI 0.22-0.36, P < 0.01), and treatment method (OR = 1.85, 95% CI 1.44-2.38, P < 0.01) were risk factors associated with PCF. CONCLUSIONS In our study, age, smoking, COPD, CAD, T-stage, previous radiotherapy, preoperative albumin, preoperative hemoglobin, tumor site, and treatment method were risk factors of PCF.

Abstract
OBJECTIVE Investigate the impact of medical comorbidities on treatment regimen and overall survival (OS) in patients with locally advanced laryngeal cancer. STUDY DESIGN Retrospective Review of the National Cancer Database (NCDB). METHODS The NCDB was queried for patients with T3 and T4 laryngeal cancer. Comorbidity scores were calculated from the Charlson-Deyo comorbidity index (CDCI). Univariate and multivariate analyses explored the association of CDCI scores on treatment regimen and OS. RESULTS 14,053 patients were analyzed. 65% of patients had a CDCI score of 0, whereas 25%, 7%, and 3% had CDCI score of 1, 2, and ≥3, respectively. As patients' CDCI increased, they became more likely to receive treatment options other than a laryngectomy or chemoradiation therapy (CRT) (P < 0.0001). Patients with CDCI ≥1 were more likely have a laryngectomy than those with CDCI 0 (P < 0.0001). In patients with T3 tumors, OS did not differ between those receiving CRT versus laryngectomy with any CDCI score. In patients with T4 tumors, laryngectomy was associated with improved OS compared to CRT across all CDCI scores except CDCI ≥3. CONCLUSION Our results support the current national guidelines with a recommendation for CRT or TL for T3 tumors and a preference for TL for T4 tumors. These outcomes are generally consistent in patients as their CDCI scores increases. LEVEL OF EVIDENCE NA Laryngoscope, 130:1459-1464, 2020.

Abstract
Introduction Soft tissue deposits is tumorous islands apart from lymph nodes and occasionally diagnosed in neck dissection specimens. Their importance has begun to be recognized, however, their value has not been investigated in laryngeal cancer as a single tumor site. Objective To investigate the prognostic value of soft tissue deposits in patients with laryngeal carcinoma. Methods Medical records of 194 patients with laryngeal carcinoma who were treated primarily by surgery and neck dissection were reviewed. Prognostic significance of soft tissue deposits was assessed along with other clinical and pathological findings. Recurrence rates, overall and disease-specific survival rates were examined. Results The incidence of soft tissue deposits was found to be 7.2% in laryngeal carcinoma. N stage was more advanced in patients who had soft tissue deposits. Regional recurrence rate was higher and disease specific and overall survivals rates were significantly lower in patients with soft tissue deposits in univariate analysis. However, in multivariate analysis, soft tissue deposits were not found as an independent risk factor. Conclusion In laryngeal carcinoma, soft tissue deposits was diagnosed in patients with more advanced neck disease and their significance was lesser than other factors including extranodal extension.

Complications, hospital length of stay, and readmission after total laryngectomy. Cancer 2016; 123:1760-1767. [PMID: 28026864 DOI: 10.1002/cncr.30483] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Revised: 10/11/2016] [Accepted: 11/14/2016] [Indexed: 11/11/2022]
Abstract
BACKGROUND The purpose of this study was to describe the 30-day incidence of complications after total laryngectomy (TL) in a high-volume institution and their impact on the hospital length of stay (LOS) and readmission rates. METHODS A retrospective cohort study of all patients who underwent TL at The University of Texas MD Anderson Cancer Center from January 1, 2010 through June 30, 2013 was conducted. The patient demographics, treatment history, LOS, and 30-day post-TL complications and readmissions were extracted from the medical record. Univariate associations were analyzed, and stepwise backward selection methods were used to fit multivariate models. RESULTS Two hundred forty-five patients were included. Complications occurred in 83 patients (33.9%) and included 3 deaths (1.2%). Wound complications occurred in 53 patients (21.6%), and 34 were pharyngocutaneous fistulas (PCFs; 13.9% overall). Thirty-four patients (13.9%) were readmitted within 30 days. A multivariate analysis revealed the following: wound complications were associated with former (odds ratio [OR], 5.1; P = .03) and current smokers (OR, 5.8; P = .02), PCFs were associated with prior wide-field radiation (OR, 3.1; P = .01) but not prior narrow-field (larynx-only) radiation (OR, 1.4; P = .61), LOS was associated with the type of flap (P = .002) and postoperative hematomas (P = .05), and readmissions were associated with preoperative hypoalbuminemia (P = .003) and postoperative wound complications (P < .001). CONCLUSIONS Complications occurred in approximately one-third of TL patients and particularly in patients with poor wound-healing risk factors such as prior smoking and radiation. As expected, LOS was longer among reconstructed patients. Readmission was associated with hypoalbuminemia and postoperative wound complications. These data can inform quality improvement efforts and the counseling of high-risk patients undergoing TL. Cancer 2017;123:1760-1767. © 2016 American Cancer Society.

Surgical site infection in clean-contaminated wounds after multimodal treatment of advanced oral squamous cell carcinoma. J Craniomaxillofac Surg 2016; 44:1957-1962. [PMID: 27810163 DOI: 10.1016/j.jcms.2016.09.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2016] [Revised: 08/16/2016] [Accepted: 09/23/2016] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVES The aim of this study was to assess the incidence rate for surgical site infections (SSI), patient- and therapy-related risk factors in UICC stage III and IV oral squamous cell carcinoma patients treated with preoperative radiochemotherapy, ablative surgery and immediate microvascular free flap reconstruction. MATERIAL AND METHODS This retrospective analysis included 85 patients with oral squamous cell carcinoma treated by neoadjuvant radiochemotherapy, tumor surgery and immediate free flap reconstruction. Patient-, therapy-related factors and blood parameters were collected for this selective cohort. RESULTS The incidence for SSI was 44.7% and for transplant loss 14.1%. Minor BMI changes (p = 0.010), diabetes (p = 0.003), edentulous status (p = 0.006) and cessation of alcohol consumption (0.034) showed to be significant patient-related risk factors. No therapy-related factors were found to be significantly influencing the risk for SSI. Neutrophil counts (p = 0.027) and GGT (p = 0.002) were found to be significantly linked to SSI. CONCLUSION The not so common treatment option for oral squamous cell carcinomas showed no more risk for SSI compared to standard treatment options. Preserving the ability for healthy nutrition has a significant impact on the development of SSI. This applies not only to the presented and particular treatment option.
