Abstract
PURPOSE The principal goal of treatment of laryngeal cancer is to eliminate a tumour while preserving laryngeal function with radio(chemo)therapy being the mainstay of treatment. The aim of this report is to present the influence of comorbidities and lifestyle factors on treatment outcomes in our cohort of patients. METHODS During the period 2009-2018, curative radio(chemo)therapy for laryngeal cancer was performed on 189 patients. RESULTS The median OS was 50.8 months, with a mean PFS of 96.5 months, mean LC of 101.4 months and a median follow-up of 38.1 months. Acute and late treatment toxicity grade 3-4 was observed in 39.2% patients and 10.1% patients, respectively. A significant effect on overall survival was confirmed for the baseline PS (performance status), severity of weight loss, baseline haemoglobin values, history of alcohol abuse, marital status and comorbidities according to the Charlson Comorbidity Index, as well as the ACE-27 and ASA scores. CONCLUSIONS In our cohort of patients treated with radio(chemo)therapy for laryngeal cancer, we found good therapeutic results and an acceptable side-effect profile. Statistically significant predictors of overall survival were the baseline PS, weight loss, anaemia, associated comorbidities, history of alcohol abuse and marital status.

Abstract
OBJECTIVES The study aimed to construct prognostic models for OS and CSS in patients with T1N0M0 glottic SCC. In addition, we used PSM to re-assess the effect of surgery alone and radiation alone. METHODS The Surveillance, Epidemiology, and End Results database was searched for patients with confirmed T1N0M0 glottic SCC. Patients with complete data were randomly divided into the training and the validation cohort (7:3), Cox-regression analysis was performed to identified significant predictors of OS and CSS. PSM was used to mimic randomized controlled the trials. Kaplan-Meier survival method and log-rank tests were utilized for survival analysis. RESULTS A total 1827 patients met the inclusion criteria. Survival analysis indicated that the patients who underwent the primary site surgery had a better OS (P = 0.002) and CSS (P = 0.008), compared with non-surgery patients. Cox-regression analysis proved that age, marital status, T1 stages, surgery, radiation, sequential treatments, and chemotherapy had significant effects on OS. While age, marital status, histologic grade, surgery, radiation, sequential treatments, and chemotherapy were substantially associated with CSS. Patients who received primary site surgery had a better OS and CSS, compared with non-surgical patients. Patients receiving radiation had a better CSS than non-radiation patients. However, patients who received sequential treatments or chemotherapy had a worse OS and CSS, compared with controlled groups. Predictive nomogram models were established to predict patients' prognosis with good consistency between the actual observation and the nomogram prediction. Before PSM, patients who underwent surgery alone had a better OS and CSS than those who received radiation alone. After PSM, patients receiving surgery still had a better OS than those receiving radiation. However, there were no statistically significant differences in CSS. CONCLUSIONS Nomogram models were developed to predict OS and CSS in patients with T1N0M0 glottic SCC. Primary site surgery could definitely increase OS and CSS, while radiation could significantly increase CSS. Using PSM, surgery alone could significantly enhance OS, as compared to radiation alone. Chemotherapy should not be recommended for early glottic carcinoma.

Management of clinically node-negative glottic squamous cell carcinoma patients according to risk-scoring model for occult lymph node metastases. Laryngoscope Investig Otolaryngol 2022; 7:715-722. [PMID: 35734062 PMCID: PMC9195031 DOI: 10.1002/lio2.762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 11/17/2021] [Accepted: 12/21/2021] [Indexed: 11/07/2022] Open
Abstract
Background Glottic squamous cell carcinoma (GSCC) is the most prevalent type of laryngeal carcinoma. The value of prophylactic lymph node dissection (LND) in resected GSCC remains controversial. This study aims to quantitatively assess the probability of occult lymph node metastasis (LNM) for GSCC patients and devise individualized postoperative radiotherapy strategies. Methods A total of 1319 patients with GSCC were retrospectively analyzed. Results GSCC patients with T1-T2 stages showed significantly lower LNM rate than those with T3-T4 stages. For patients with T3-T4 GSCC, multivariate logistic analyses indicated that three factors-maximum tumor diameter (MTD) of more than 2.0 cm, relatively low differentiation, and tumor invasive depth of no less than 1.0 cm-were independent risk factors for the existence of LNM. A predictive nomogram was established based on these factors. The accuracy and validity of our model were verified by 0.716 and remained at 0.717 after 1000 bootstrapping. The calibration curve was also plotted and showed a favorable agreement. The patients were stratified into two groups based on their individual LNM risk points. Possible LNM rates for low-risk and high-risk subgroups were 4.7% and 25.2%, respectively. Conclusions A new post-operative strategy selection flow chart was established based on our newly created nomogram which can effectively predict the individualized possibility of occult LNM for GSCC patients. For clinical T3-4N0 patients in the high-risk subgroup, prophylactic dose post-operative radiation therapy is recommended. However, for all those clinically diagnosed as T1-2N0 stage, regular follow-up is sufficient in view of the low occult LNM rate.Level of Evidence: 2a.

Abstract
OBJECTIVES To establish and validate a predictive model integrating with clinical and dual-energy CT (DECT) variables for individual recurrence-free survival (RFS) prediction in early-stage glottic laryngeal cancer (EGLC) after larynx-preserving surgery. METHODS This retrospective study included 212 consecutive patients with EGLC who underwent DECT before larynx-preserving surgery between January 2015 and December 2018. Using Cox proportional hazard regression model to determine independent predictors for RFS and presented on a nomogram. The model's performance was assessed using Harrell's concordance index (C-index), time-dependent area under curve (TD-AUC) plot, and calibration curve. A risk stratification system was established using the nomogram with median scores of all cases to divide all patients into two prognostic groups. RESULTS Recurrence occurred in 39/212 (18.4%) cases. Normalized iodine concentration in arterial (NICAP) and venous phases (NICVP) were verified as significant predictors of RFS in multivariate Cox regression (hazard ratio [HR], 4.2; 95% confidence interval [CI]: 2.3, 7.7, p < .001 and HR, 3.0; 95% CI: 1.5, 5.9, p = .002, respectively). Nomogram based on clinical and DECT variables was better than did only clinical variables. The prediction model proved well-calibrated and had good discriminative ability in the training and validation samples. A risk stratification system was built that could effectively classify EGLC patients into two risk groups. CONCLUSIONS DECT could provide independent RFS indicators in patients with EGLC, and the nomogram based on DECT and clinical variables was useful in predicting RFS at several time points. KEY POINTS • Dual-energy CT(DECT) variables can predict recurrence-free survival (RFS) after larynx-preserving surgery in patients with early-stage glottic laryngeal cancer (EGLC). • The model that integrates clinical and DECT variables predicted RFS better than did only clinical variables. • A risk stratification system based on the nomogram could effectively classify EGLC patients into two risk groups.

Abstract
Purpose Local failure after endoscopic laryngeal surgery (ELS) for early glottic cancer mounts a challenge to researchers to investigate risk factors of recurrence. The present study was therefore designed to explore the prognostic factors in patients who underwent ELS for early glottic cancer. Patients and Methods We reviewed 328 patients with T1-2N0 glottic cancer who were treated with either ELS or open surgery between 2007 and 2018 at our institution. Survival, univariate and multivariate analyses were performed in different groups (ELS vs open surgery; < 65 vs ≥ 65 years). Results Age was discovered to be the independent prognostic factor of DFS for patients treated with ELS (HR = 3.673, p = 0.003), but not for patients who underwent open surgery. Survival analysis performed on young patients (< 65 years) showed that survival outcomes between different surgery modalities were significantly different (ELS vs open surgery: five-year DFS: 72.5 vs 84.7%, p = 0.034). Univariate and multivariate analyses further confirmed the finding, whereas these results did not appear in old patients (≥ 65 years). Conclusion Young patients (< 65 years) treated with ELS had less favorable oncologic outcomes than those treated with open surgery. Young patients (< 65 years) are advised to consider open surgery over ELS.

Current indications for adjuvant treatment following transoral laser microsurgery of early and intermediate laryngeal cancer. Curr Opin Otolaryngol Head Neck Surg 2021; 29:79-85.

Abstract
PURPOSE OF REVIEW This review summarizes the information in the literature on the indications for adjuvant therapy after transoral laser microsurgery (TLM) for early/intermediate stage laryngeal cancer. RECENT FINDINGS A high rate of 'nonevaluable' margins after TLM significantly complicates decision-making concerning adjuvant therapy. However, consensus grows that second-look TLM in patients with multiple superficial and deep positive margins is more sensible than sending these patients systematically for adjuvant radiotherapy (RT). SUMMARY The classical adagium: 'Failure to achieve negative margins indicates need for adjuvant RT' does not translate automatically to patients with glottic cancer treated by TLM. Rather, specifically patients with multiple superficial positive margins and positive deep margins after TLM need careful judging what constitutes the best additional adjuvant treatment. Second-look resection is nowadays regarded as the preferred adjuvant treatment for many of these patients whereas RT is reserved for those in whom a second look TLM is judged unlikely to result in 'true negative margins.' Additionally, when the pathology of the re-resection reveals multiple foci of residual disease or suggests again a resection with positive margins, adjuvant postoperative RT is likely to result in a better local control. If this strict selection of patients for adjuvant RT is adhered to carefully, oncological and functional results will be optimal.

Abstract
BACKGROUND Glottic squamous cell carcinoma (SCC) in stages I or II can be treated by transoral CO2 laser microsurgery (TLM) or exclusive radiotherapy (RT). OBJECTIVES To compare the oncological results of patients treated with TLM, to those treated with RT, in a tertiary hospital. MATERIAL AND METHODS Data from patients diagnosed with glottic SCC in stages I and II between 2004 and 2018 were analyzed. Response to treatment was studied in terms of recurrence, local control and laryngeal preservation. RESULTS Of 164 patients, 63.41% received treatment with TLM and 36.58% with RT. 26.21% presented a recurrence or progression of the tumor. Both treatments obtained good local control rates (84.15% in the case of TLM and 89.6% in the case of RT) and no significant association was found between tumor recurrence and type of treatment, nor with the involvement of the anterior commissure. However, treatment with RT obtained worse laryngeal preservation rate compared to TLM (81.6% and 100% respectively) (p < .001LR). Conclusions and significance: Both treatments obtained good oncological results. There were no significant differences regarding local control. However, TLM obtained a better laryngeal preservation rate. The involvement of the anterior commissure was not a poor prognosis factor for tumor recurrence.

Abstract
Aim The aim of this study was to compare the outcomes, patterns of failure and laryngeal preservation rates in patients with T1N0 glottic cancer treated with surgery or radiotherapy. Materials/methods Retrospective study of T1N0 glottic cancer patients treated in our institution between January 2007 and December 2017. Histologically proven squamous cell carcinoma patients, treated with upfront cordectomy/partial laryngectomy (S group) or radiotherapy (RT group) were included. Elective treatment of the neck was not permitted. Local failure (LF), disease-free survival (DFS), ultimate disease-free survival (UDFS), laryngectomy-free survival (LFS), disease-specific mortality (DSM) and overall survival (OS) were evaluated. Results Two hundred and one patients were eligible (172 S group, 29 RT group), with a median follow-up of 38.8 months. Overall, 33 (16%) patients had a recurrence, 30 (17%) in the S group and 3 (10%) in the RT group. Local failure was the predominant site of failure (28 S, 2 RT). Overall, of all those that were salvaged, 17 (8%) underwent total laryngectomy (15 S, 2 RT). There was no significant difference in the 5-year cumulative incidence of LF (20.8% S, 8.1% RT, p = 0.138), 5-y LFS (85.0% vs. 91.7%, p = 0.809), 5-y DFS (67.5% vs. 82.1%, p = 0.343), 5-y UDFS (82.5% vs. 90.3%, p = 0.647) and 5-y OS (84.5% vs. 90.3%, p = 0.892). Multivariate analysis showed no correlation between initial treatment and the analyzed outcomes. Conclusion Primary surgery or radiotherapy were similar first line options, since they do not differ in all outcomes. Patients' and physician's preferences must be considered when choosing first treatment.

Abstract
For the treatment of early and locally advanced glottic laryngeal cancer, multiple strategies are available. These are pursued and supported by different levels of evidence, but also by national and institutional traditions. The purpose of this review article is to compare and discuss the current evidence supporting different loco-regional treatment approaches in early and locally advanced glottic laryngeal cancer. The focus is kept on randomized controlled trials, meta-analyses, and comparative retrospective studies including the treatment period within the last twenty years (≥ 1999) with at least one reported five-year oncologic and/or functional outcome measure. Based on the equipoise in oncologic and functional outcome after transoral laser surgery and radiotherapy, informed and shared decision-making with and not just about the patient poses a paramount importance for T1-2N0M0 glottic laryngeal cancer. For T3-4aN0-3M0 glottic laryngeal cancer, there is an equipoise regarding the partial/total laryngectomy and non-surgical modalities for T3 glottic laryngeal cancer. Patients with extensive and/or poorly functioning T4a laryngeal cancer should not be offered organ-preserving chemoradiotherapy with salvage surgery as a back-up plan, but total laryngectomy and adjuvant (chemo) radiation. The lack of high-level evidence comparing contemporary open or transoral robotic organ-preserving surgical and non-surgical modalities does not allow any concrete conclusions in terms of oncological and functional outcome. Unnecessary tri-modality treatments should be avoided. Instead of offering one-size-fits-all approaches and over-standardized rigid institutional strategies, patient-centered informed and shared decision-making should be favored.

Abstract
Background and Purpose: Larynx cancer represents one of the most frequently diagnosed head and neck malignancies, which is most often confined to the glottic area. The aim of this study was to report the oncological outcome and identify prognostic factors in early-stage glottic squamous cell carcinoma treated with radiotherapy. Material and Methods: Patients (n = 761) diagnosed and treated in 10 centers between 1990 and 2015 were retrospectively analyzed. Probabilities of loco-regional control (LRC) and overall survival (OS) were calculated and possible prognostic factors were analyzed using Cox proportional hazards models. Results: The median follow-up was 63 months (range: 2-243). Three hundred and sixty-four, 148 and 249 patients had cT1a, cT1b, and cT2 stage I-II disease, respectively. Five and 10-years LRC/OS rates in the whole cohort were 83/82% and 80/68%, respectively. Three patients developed distant recurrences. In univariate analysis, male sex (HR: 3.49; 95% CI: 1.47-11.37; p < 0.01), T2 vs. T1a (HR: 1.62; 95% CI: 1.08-2.43; p = 0.02) and anterior commissure involvement (ACI) (HR: 1.66; 95% CI: 1.38-2.45; p < 0.01) were associated with impaired LRC. In multivariate analysis, male sex (HR: 3.42; 95% CI: 1.44-11.17; p < 0.01) and ACI (HR: 1.51; 95% CI: 1.01-2.28; p = 0.047) remained poor prognostic factors. No relation of treatment technique and biologically equivalent dose (BED) to oncological outcome was identified except for higher BED10(L = 25; T = 1) yielding better LRC in T1a tumors (p = 0.04) in univariate analyses. Conclusion: Our results highlight the negative impact of ACI on tumor control. A less-expected finding was the impact of sex on tumor control. Further research is needed to validate its prognostic value and investigate any related biologic or behavioral factors, which may be modified to improve oncologic outcome.

Abstract
PURPOSE Presentation of long-term results of radiation treatment in patients with T1 glottic cancer and evaluation of prognostic factors. METHODS We performed a retrospective analysis in a group of 569 patients with T1 squamous cell glottic carcinoma treated with radiotherapy at the Center of Oncology in Cracow between 1977 and 2007. In all, 503 (88%) patients presented with T1a stage disease and 66 (12%) with T1b. Anterior commissure infiltration was present in 179 (31%) patients. Average hemoglobin level prior to therapy was 13.9 g/dl. Using the body mass index (BMI), 114 (20%) patients were underweight, and 91 (16%) were overweight. Median time between collecting tumor specimen and beginning of radiotherapy was 56 days (range 14-145 days). Treatment regimen was normofractionated with single fraction ≤2 Gy in 102 (18%) and hypofractionated in 467 (82%) patients. RESULTS The 5‑ and 10-year overall survival (OS), disease-specific survival (DSS) and local control (LC) rates were 85 and 68%, 88 and 86%, 89 and 87%, respectively. Multivariate analysis showed that tobacco smoking, low hemoglobin level (<13 g/dl), anterior commissure infiltration, fraction dose ≤2 Gy and time from collecting specimen to beginning of therapy longer than 30 days had negative impact on LC and DSS. Patients' age over 60 years, worse performance status and malnutrition (BMI <18.5) had negative impacts on OS. CONCLUSIONS Radiotherapy is a highly effective treatment method in patients with T1N0M0 glottic cancer. LC and DSS may be improved following hypofractionation, smoking cessation, and shortening of waiting-time until start of treatment. OS was mainly influenced by nutritional and performance status.

Abstract
BACKGROUND AND OBJECTIVES Transoral laser surgery is the optimal surgical treatment modality for the early stages of glottic cancer. To allow for further treatment to be as effective and as minimal as possible, persistent or recurrent tumors should be detected very soon. The main aim is to minimize the risk of necessity of performing a total laryngectomy. Flexible videoendoscopy with narrow band imaging (NBI) was recommended by the European Laryngological Society as a diagnostic method for the follow-up of patients treated for laryngeal cancer. Nevertheless, the efficacy of this technique has not been extensively studied in patients after transoral laser cordectomies for vocal fold cancer. The aim of this study was to evaluate the efficacy of in-office transnasal NBI flexible videoendoscopy in the follow-up of patients after transoral laser cordectomy for glottic cancer. We also focused on describing the specific characteristics of recurrent tumor appearance. MATERIALS AND METHODS The presented study was conceived as a prospective study. Ninety-four consecutive patients who underwent transoral laser cordectomy for severe dysplasia, Tis, T1, and T2 glottic cancer in the period from June 2010 to August 2015 were enrolled in the study. All patients were postoperatively regularly followed using transnasal videoendoscopic examinations with NBI. Whenever a suspect lesion was identified during in-office examination, its nature was proven histologically. RESULTS We discovered 23 suspect findings in 21 patients by means of flexible videoendoscopy with NBI. Fifteen (65.2%) of them were histologically confirmed as recurrent tumors, whereas in 8 (34.8%) of them, the recurrent tumor was not proven. In two patients, the recurrent tumor was evident on computed tomography or magnetic resonance imaging, but NBI endoscopy did not reveal relapsing disease. The rest (71 patients) were considered true negative. Of the 15 recurrent tumors detected by NBI-coupled videoendoscopy, 8 (53.3%) were identified as submucosal masses with nonsignificant or no vascular changes, 4 (26.7%) were noted as the progression of leukoplakia without visible vascular changes, only 2 (13.3%) showed typical vascular changes, and, in 1 (6.7%) case, evident, significantly exophytic tumor with pathological vascularization was discovered. The sensitivity, specificity, and positive and negative predictive values of the in-office transnasal videolaryngoscopy with NBI were calculated to be 88%, 92%, 71%, and 97%, respectively. CONCLUSIONS The results of the study demonstrate that transnasal endoscopy with NBI in an outpatient setting is an excellent method for the follow-up of patients after transoral laser cordectomy for glottic cancer. The method achieves high sensitivity, specificity, and negative predictive value and a slightly low positive predictive value. Nevertheless, we must bear in mind that recurrent tumors after previous endoscopic resection may have a completely different appearance than new tumors originating from previously untreated tissues.

Long-Term Experience of Chemoradiotherapy Combined with Deep Regional Hyperthermia for Organ Preservation in High-Risk Bladder Cancer (Ta, Tis, T1, T2). Oncologist 2019; 24:e1341-e1350. [PMID: 31292267 PMCID: PMC6975936 DOI: 10.1634/theoncologist.2018-0280] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 02/11/2019] [Indexed: 01/19/2023] Open
Abstract
This article reports on the different treatments for bladder cancer and related effects on frequency of bladder preservation, disease‐free survival, and overall survival, with a focus on the efficacy and safety of chemoradiotherapy combined with regional deep hyperthermia of high‐risk bladder cancer after transurethral resection of bladder tumor. Background. The aim of this study was to evaluate the efficacy and safety of chemoradiotherapy (RCT) combined with regional deep hyperthermia (RHT) of high‐risk bladder cancer after transurethral resection of bladder tumor (TUR‐BT). Materials and methods. Between 1982 and 2016, 369 patients with pTa, pTis, pT1, and pT2 cN0–1 cM0 bladder cancer were treated with a multimodal treatment after TUR‐BT. All patients received radiotherapy (RT) of the bladder and regional lymph nodes. RCT was administered to 215 patients, RCT + RHT was administered to 79 patients, and RT was used in 75 patients. Treatment response was evaluated 4–6 weeks after treatment with TUR‐BT. Results. Complete response (CR) overall was 83% (290/351), and in treatment groups was RT 68% (45/66), RCT 86% (178/208), and RCT + RHT 87% (67/77). CR was significantly improved by concurrent RCT compared with RT (odds ratio [OR], 2.32; 95% confidence interval [CI], 1.05–5.12; p = .037), less influenced by hyperthermia (OR, 2.56; 95% CI, 0.88–8.00; p = .092). Overall survival (OS) after RCT was superior to RT (hazard ratio [HR], 0.7; 95% CI, 0.50–0.99; p = .045). Five‐year OS from unadjusted Kaplan‐Meier estimates was RCT 64% versus RT 45%. Additional RHT increased 5‐year OS to 87% (HR, 0.32; 95% CI, 0.18–0.58; p = .0001). RCT + RHT compared with RCT showed a significantly better bladder‐preservation rate (HR, 0.13; 95% CI, 0.03–0.56; p = .006). Median follow‐up was 71 months. The median number of RHT sessions was five. Conclusion. The multimodal treatment consisted of a maximal TUR‐BT followed by RT; concomitant platinum‐based chemotherapy combined with RHT in patients with high‐grade bladder cancer improves local control, bladder‐preservation rate, and OS. It offers a promising alternative to surgical therapies like radical cystectomy. Implications for Practice. Radical cystectomy with appropriate lymph node dissection has long represented the standard of care for muscle‐invasive bladder cancer in medically fit patients, despite many centers reporting excellent long‐term results for bladder preserving strategies. This retrospective analysis compares different therapeutic modalities in bladder‐preservation therapy. The results of this study show that multimodal treatment consisting of maximal transurethral resection of bladder tumor followed by radiotherapy, concomitant platinum‐based chemotherapy combined with regional deep hyperthermia in patients with Ta, Tis, T1–2 bladder carcinomas improves local control, bladder‐preservation rate, and survival. More importantly, these findings offer a promising alternative to surgical therapies like radical cystectomy. The authors hope that, in the future, closer collaboration between urologists and radiotherapists will further improve treatments and therapies for the benefit of patients.

Abstract
Stochastic long-term damages at relatively low doses have the potential for cancer induction. For the first time we investigated the occurrence of breast cancer in female patients after radiotherapy of non-malignant disorders of the shoulder and made a comparison with the estimated spontaneous incidence of mammary carcinoma for this cohort. In a geographically defined district with a population of approximately 100.000 inhabitants, comprehensive data of radiological diagnostics and radiotherapy were registered nearly completely for 41 years; data included mammography and radiotherapy of breast cancer patients as well as of non-malignant disorders. Within this population a collective of 158 women with radiotherapy of the shoulder was investigated. Radiotherapy was performed with cobalt-60 photons (Gammatron) with an average cumulative-dose of 6 Gy. The average follow-up time was 21.3 years. Patients were 55 years old (median) when radiotherapy of the shoulder was performed. Seven patients (4.4%) developed breast cancer after a median of 21 years. According to the incidence statistics, 9.4 +/- 1.8 (95%CI) cases (5.9%) would be expected. In regard to the irradiated shoulder neither the ipsilateral nor the contralateral breasts showed increased rates of breast cancer. An induction of additional breast cancer caused by radiation of non-malignant disorders of the shoulder wasn't detected in the investigated cohort.

Is there a patient population with squamous cell carcinoma of the head and neck region who might benefit from de-intensification of postoperative radiotherapy? : A monocentric retrospective analysis of a previously defined low-risk patient population treated with standard-of-care radiotherapy. Strahlenther Onkol 2019; 195:482-495. [PMID: 30610355 DOI: 10.1007/s00066-018-1415-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Accepted: 12/11/2018] [Indexed: 12/14/2022]
Abstract
PURPOSE The aim of this retrospective study was to evaluate the clinical outcome of a previously defined low-risk patient population with completely resected (R0) squamous cell carcinoma of the oral cavity, oropharynx, larynx (pT1-3, pN0-pN2b), hypopharynx (pT1-2, pN0-pN1), and the indication for postoperative radio(chemo)therapy. PATIENTS AND METHODS According to predefined criteria, 99 patients with head and neck squamous cell carcinoma (SCC) who were treated at our institution from January 1, 2005 to December 31, 2014, were available for analysis. The Kaplan-Meier method was used for calculating survival and incidence rates. For univariate comparative analysis, the log-rank test was used for analyzing prognostic clinicopathologic parameters. RESULTS Median follow-up was 67 months. Cumulative overall (OS) and disease-free survival (DFS) were 97.9%/94.7%/88.0% and 96.9%/92.6%/84.7% after 1, 2, and 5 years, respectively. Cumulative incidence of loco-regional recurrence (LRR), distant metastases (DM), and second cancer (SC) were 1.0%/1.0%/4.9%, 0.0%/3.4%/5.8%, and 2.1%/4.2%/13.1%, respectively. In univariate comparative analysis, location of the primary tumor in the oropharynx was a significant predictor for increased OS (p = 0.043) and DFS (p = 0.048). CONCLUSION Considering the low disease relapse rates and high rates of therapy-induced late side effects, as well as the increased risk of developing SC, a prospective multicentric trial investigating de-escalation of radiotherapy in this clearly defined low-risk patient population was started and is still recruiting patients (DIREKHT-Trial, NCT02528955).

Abstract
PURPOSE The second primary cancer (SPC) incidence after treatment with platinum-based chemotherapy and cetuximab in combination with radiotherapy has not been previously reported. Our aim was to compare SPC risk following radiotherapy in combination with these agents for the treatment of head and neck squamous cell carcinoma (HNSCC). METHODS The charts of 296 cases treated for loco-regionally advanced HNSCC between 2009 and 2015 were retrospectively reviewed for patient, tumor, and procedural characteristics. All patients were planned to undergo radiotherapy either with platinum compounds (group: Platinum) or monoclonal antibody cetuximab (group: Cetuximab). A third group of patients switched from platinum compounds to cetuximab due to toxicity (group: Switch). Treatment groups were evaluated for the incidence of SPC with log-rank test. Possible confounders were investigated with multivariate Cox's proportional hazards model. All tests were two-sided, and a p < 0.05 was set to indicate statistical significance. RESULTS Median follow-up was 36 months. Platinum, Cetuximab, and Switch groups consisted of 158, 101, and 37 patients, respectively. Three-year overall survival in the whole cohort was 70%. The rate of SPC was comparable between Platinum (9.2%) and Cetuximab (11.5%) groups (p = 0.98), whereas the patients in the Switch group were exposed to a significantly higher incidence of SPC (23.3%) in 3 years (p = 0.01). The multivariate model indicated Switch to be the only variable correlating with an increased risk for SPC. CONCLUSIONS The Switch strategy may expose the patients to an increased risk of developing SPC. The use of switch should be advocated with caution until robust pre-clinical and clinical data are available.

There are conflicting reports about whether radiotherapy or surgery is optimal for early‐stage laryngeal squamous cell carcinoma (LSCC), although both have recently been recommended. Patients with T1‐2N0M0 LSCC in the population‐based SEER database who underwent radiotherapy or surgery were reviewed. Propensity score matching was used to eliminate the baseline variations. After matching, 1913 pairs of patients were included. Overall, patients who received radiotherapy had worse cancer‐specific survival than patients with surgery. After stratification, the survival in patients who received radiotherapy was worse with respect to the following characteristics: ≤60 years of age; T1a glottis cancer; well‐differentiated tumors; and with married status. In other patients, survival outcomes were similar in patients who received radiotherapy and underwent surgery. Our results indicate that radiotherapy is not preferable in early‐stage LSCC patients who are ≤60 years of age, have T1a glottis cancer or well‐differentiated tumors, or are married. In other patients, both radiotherapy and surgery are comparable. However, our results cannot be a reference before controlled, prospective trials are performed.
