The purpose of this study is to assess patient, tumour and treatment related factors on quality of life (QoL) outcomes of patients who received definitive or postoperative radiotherapy +/- chemotherapy for head and neck (H&N) cancer. In this cross-sectional study, 110 H&N cancer patients were evaluated in follow-up visit and were asked to fill out the European Organisation for Research and Treatment of Cancer QoL Core Questionnaire (QLQ-C-30) and H&N Module (QLQ-H&N35). Patients were also graded for their late side effects using EORTC/RTOG scoring system. The QLQ C-30 and QLQ-H&N35 mean scores were compared using ANOVA analysis for these variables: age, gender, occupation, educational status, social security status, place of residence, tumour localization, clinical stage, comorbidity, Karnofsky performance score, treatment modality and side effects. Median follow-up was 29 (4-155) months. Tumour localization was significant factor affecting physical (P = 0.03), social (P = 0.01), cognitive (P = 0.002) functioning. Treatment modality had significant impact on the physical (P = 0.02) and cognitive scores (P = 0.008). Global QoL was affected significantly by disease stage (P = 0.01) and occupation (P = 0.01). The QLQ-H&N35 scores were found significantly higher in patients with moderate/severe late morbidity. Tumour localization and the treatment modality are the most important factors affecting the QoL of H&N cancer patients treated definitively.
For laryngeal cancer, surgical excision of the primary tumor should be undertaken with the aim of achieving tumor-free margins. Adequate pathological assessment of the specimen and the competency of the treatment center play a crucial role in achieving cure. The present study aimed to analyze the significance of place of surgery on the outcome of patients with laryngeal cancer who underwent surgical operation in other centers and were subsequently referred to Doküz Eylul University Head and Neck Tumour Group (DEHNTG) for postoperative irradiation. Patients were divided into three groups according to their place of surgery. The first group (Group I) consisted of patients who had their surgical operation at DEUH. Patients in the second group (Group II) were referred from centers with oncological surgical experience. The third group (Group III) consisted of patients referred from hospitals with no surgical teams experienced in head and neck cancer treatment. The clinical and pathological features of patients in these three groups were analyzed to assess the impact of place of surgery on clinical outcome as well as the prognostic factors for survival. The study population consisted of 253 patients who were treated between 1991 and 2006 with locally advanced laryngeal cancer according to the protocol of DEHNTG. The median follow-up was 48 (3-181) months. The 5 years overall, loco-regional disease-free and distant disease-free survivals were 66, 88 and 91%, respectively. When patients' clinical and histopathological features were analyzed for the impact of place of surgery, surgical margin positivity rates were found to be higher in Group III (P = 0.032), although the other two groups had more advanced clinical and pathological N stage disease (P = 0.012, P = 0.001). In multivariate analysis, older age (P < 0.0001), presence of perinodal invasion (P = 0.012), time interval between surgery and radiotherapy longer than 6 weeks (P = 0.003) and tumor grade (P = 0.049) were the most significant factors. For loco-regional failure-free survival, advanced clinical stage (P = 0.002), place of surgery (P = 0.031) and presence of clinical subglottic invasion (P = 0.029) were shown to be important prognostic factors. For distant metastasis-free survival, only pathological (+) lymph node status (P = 0.046) was a significant factor in multivariate analysis. The significance of place of surgery as well as other well-known prognostic factors underlines the importance of an experienced multidisciplinary treatment team if best results are to be obtained for the patient.
Purpose The aim was to evaluate the treatment outcomes and prognostic characteristics of patients with early-stage glottic laryngeal carcinoma who underwent radical radiotherapy (RT) with different techniques. Patients and Methods Radiotherapy was applied using the 2D conventional technique between 1991 and 2004 (130 patients), 3DCRT until 2014 (125 patients), and by VMAT until January 2017 (44 patients). Clinical T stages were 38 (12.7%) for Tis, 209 (69.9%) for T1, and 52 (17.4%) for T2. Radiotherapy technique and energy, anterior commissure involvement, and stage were analyzed as prognostic factors. Results The median total dose was 66 (50–70) Gy, and median follow-up time was 72 (3–288) months; 5-year disease-specific survival (DSS) rates were 95.8%, 95.5%, and 88.6%, respectively, in Tis, T1, and T2 stages. In multivariate analyses, anterior commissure involvement was found significant for all survival and local control rates. The patients treated with VMAT technique had better local control and DSS rates. However, these results were not statistically significant. Conclusion In early-stage laryngeal carcinomas, radical RT is a function sparing and effective treatment modality, regardless of treatment techniques.
This is the first series investigating tumor-stroma proportion as a prognostic marker in laryngeal carcinomas proposing a new method, but the findings do not support tumor-stroma proportion as a prognostic marker.
