Transoral Laser Microsurgery vs Radiotherapy for Early Glottic Cancer: Study at Tertiary Care Center in India (original) (raw)

Retrospective analysis of factors influencing oncologic outcome in 590 patients with early-intermediate glottic cancer treated by transoral laser microsurgery

Background. The purpose of this study was to identify the factors influencing oncologic outcomes for patients with early-intermediate glottic cancer treated by transoral laser microsurgery (TLM). Methods. This was a retrospective mono-institutional study. A total of 590 patients with cTis-cT3 glottic cancer underwent TLM with curative intent. Results. TLM alone was performed in 538 patients (91.2%) and TLM followed by adjuvant radiotherapy (RT) was done in 52 (8.8%). Five-year recurrence-free survival (RFS) and 10-year overall survival (OS) were 85.3% and 74.7%, respectively. The larynx-preservation ratio was 95.9%. In particular, from our data, we found that occult metastases were rare (1.2%); preventive tracheotomy was not necessary; the local recurrence rate of Tis was similar to that in the T2 and T3 group; and no major or lethal complications were observed. Conclusion. Age (>60 vs 60), type of cordectomy (IV vs III), status of margins, fixed arytenoid, and pathologic T classification, were the variables associated with RFS, OS, and organ-preservation rate.

Comparison of Oncologic Outcomes Between Radiation Therapy and Transoral Laser Microsurgery for Early Glottic and Supraglottic Squamous Cell Carcinoma; a Retrospective Cohort Study with Literature Review

International Journal of Cancer Management

Background: Laryngeal cancer is known as the second most common airway cancer. These tumors are usually diagnosed early; thus, it is important to choose the optimal treatment modality. Several studies are comparing transoral laser microsurgery (TLM) and radiotherapy in early-stage laryngeal cancer. Due to a paucity of high-quality research and the lack of conclusive randomized prospective studies, standard care for early glottic cancer is still a matter of controversy. Methods: In this retrospective cohort study, T1-T2N0M0 laryngeal cancer patients who underwent TLM or radiotherapy were compared with statistical methods in terms of Recurrence Rate, Organ (Larynx) Preservation Rate, Mortality Rate, and Overall Survival. Results: A total of 123 patients were evaluated in this study, 65 of whom underwent TLM and 58 underwent radiotherapy. There was no significant difference in demographic and medical characteristics of patients. The rate of recurrence was 27.3% in the TLM group and 43....

At their last followup, no patients assessed had any difficulty swallowing relating...

Quality of life and functional outcomes in the management of early glottic carcinoma: a systematic review of studies comparing radiotherapy and transoral laser microsurgery

Clinical Otolaryngology, 2010

Background: Early glottic carcinoma can be managed by radiotherapy and transoral laser microsurgery with similar control and survival rates. The functional and quality of life outcomes of these interventions are therefore important to guide management. Objective of review: To compare the different treatment modalities for early glottic carcinoma with respect to quality of life, post-treatment voice character and swallowing outcomes. Type of review: A systematic review of the literature with defined search strategy. Search strategy: Searches of EBM databases, and literature databases using key words: glotti*, laryn*, neoplasm, radiotherapy and laser surgery from 1970 to November 2009. Articles were screened for relevance using predetermined inclusion and exclusion criteria. Evaluation method: Articles reviewed by authors and data compiled in tables for analysis. Results: No randomised controlled trials were identified. There were 15 studies reporting vocal outcomes, and

Revisiting the Concept of Non- and Minimally Invasive Interventions in Early Glottic Cancer – Part II: Single Therapy Should be Favored over the Combination of Transoral Laser Microsurgery and Radiotherapy, Regarding the Postinterventional Voice Quality

International Archives of Otorhinolaryngology, 2021

Introduction Early glottic cancer (EGC) is associated with a high cure rate. Hence, patients and physicians also focus on the impact of the proposed treatment on the speaking function of the preserved larynx. Objectives The present study assessed the impact of single-modality treatment (transoral laser microsurgery [TLM], or radiotherapy) or combination therapy for EGC on postinterventional voicing and explored factors which might explain the related perceptions. Methods A total of 108 patients filled in the voice handicap index 10 questionnaire, 1 and 2 years postinterventionally. Non-parametric tests were used for the respective statistical analyses. Results Sixty-four patients were treated with TLM, 15 with radiotherapy, and 29 with both modalities. Transoral microsurgery and radiotherapy were associated with postinterventional dysphonia, which attenuated between the first and second postintervention year (p = 0.000). No association between sociodemographic parameters and the att...

Life quality improvement in hoarse patients with early glottic cancer after transoral laser microsurgery

Head & neck, 2017

The purpose of this study was to evaluate the recovery kinetics of voice and quality of life (QOL) over time in patients with early glottic cancer who underwent transoral laser microsurgery (TLM). A prospective cohort study was conducted in which acoustic and aerodynamic voice assessments and QOL analyses were done using health-related questionnaires (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30-questions [EORTC-QLQ-C30] and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck 35-questions [EORTC-QLQ-H&N35]) were administered at designated times. Most voice laboratory parameters worsened during the first month, then recovered to baseline after 6 months. The QLQ-H&N35 speech subscale was significantly improved. Among the voice laboratory parameters, pretreatment harmonics-to-noise ratio was an independent predictor (P = .041) for improvement on the speech subscale at the endpoint. De...

Transoral laser microsurgery for early glottic cancer as one-stage single-modality therapy

The Laryngoscope, 2013

Objectives/Hypothesis: A study was undertaken to determine the oncologic outcomes in a consecutive series of early glottic carcinomas treated with transoral CO 2 laser microsurgery (TLM) as a one-stage single-modality therapy, without any postoperative radiation therapy or retreatment with laser. We further evaluated correlations between the oncologic outcomes and clinicopathologic factors including tumor location and surgical margin. Study Design: Retrospective analysis of medical records. Methods: The medical records of 118 consecutive patients with early stage (T1, T2) glottic carcinoma who underwent TLM by a single surgeon as an initial treatment from 1997 to 2011 were retrospectively reviewed. The oncologic outcomes were evaluated, and correlations to clinicopathologic factors were analyzed. Results: The 5-year disease-free survival, ultimate local control with laser alone, disease-specific survival, overall survival, and organ preservation rates were 87.9%, 94.2%, 99.0%, 92.2%, and 96.2%, respectively. Neither the reported surgical margin nor the extension of tumor to the anterior commissure, arytenoid, subglottis, and ventricle showed any significant impact on local control or survival. Conclusions: Transoral CO 2 laser microsurgery as one-stage single-modality therapy resulted in a high rate of local control and a high survival rate in selected cases of early glottic carcinoma, regardless of the location of tumor and histopathology report on the surgical margin.

Comparison of external radiotherapy, laser microsurgery and partial laryngectomy for the treatment of T1N0M0 glottic carcinomas: a retrospective evaluation

Radiotherapy and Oncology, 1998

The aim of this study was to retrospectively compare the efficacy and functional results of three treatment options for T1N0M0 glottic carcinomas applied in a single institution. Materials and methods: One hundred six charts of patients with biopsy-proven T1N0M0 glottic carcinomas treated between 1979 and 1995 were reviewed. There were 81 T1a and 25 T1b tumors. Forty-one patients were treated by radiotherapy (RT) (median dose of 64 Gy), 34 patients were treated by partial laryngectomy (PL) and 31 patients were treated by laser microsurgery (L) of which 10 received postoperative RT for positive margins. In 18 patients, a perceptual voice rating on a visual scale was performed by the patients themselves, three non-speech specialists and two speech therapists. Results: With a median follow-up time of 63.5 months, the 5-and 10-year loco-regional control probabilities reached 91 and 87%, respectively, without any difference between the treatment groups. After salvage laryngectomy, the 5-and 10-year loco-regional control probabilities reached 97% without any difference between the treatment groups. For the whole population, overall survival reached 78 and 62.4% at 5 and 10 years, respectively. The actuarial incidence of second primary reached 19% at 10 years. Regarding the quality of voice, overall there was a trend towards a worse satisfaction index, more hoarseness and more breathiness after PL than after L or RT. Conclusions: Our data suggested that assuming proper selection of patients, RT and L yielded similar outcomes and functional results. Local recurrence can be adequately salvaged by surgery. On the other hand, PL appeared to yield similar loco-regional control probability but with a worse quality of voice.
