“…Therefore, further multicenter studies on a larger number of patients and long follow up periods are warranted. Additionally further studies on the more recent imaging modalities such as PET/MRI or diffusion weighted MRI [ 18 , 19 ], are needed to verify the accuracy of these modalities, and to decrease the discrepancy between clinical and pathological staging of laryngeal carcinoma.…”

Objectives The aim of this study was to investigate the degree of discrepancy between the clinical and pathological staging of laryngeal carcinoma, and the potential impact of this discrepancy on the outcomes and prognosis. Methods This study was conducted on 127 patients who underwent total laryngectomy over five years (October 2016–October 2021). Data collected from pretherapeutic clinical staging regarding the extent of the tumor affection of different laryngeal subsites was compared to the postsurgical pathological assessment. Results Overall, 12 out of 127 patients (9.4%) in the current study, were clinically over-staged from T3 to T4 due to radiological diagnosis of tumor infiltration of laryngeal cartilages that proved pathologically to be free of tumor. Additionally, discordance in the N stage was found in 12.6% (n = 16). However, stage discrepancy did not have a significant impact on the prognosis and survival. Conclusion Discordance between clinical and pathological TNM staging of laryngeal carcinoma may affect the decision making and the choice of the treatment options. Some improvement can be probably achieved with advancements and higher accuracy of the preoperative diagnostic tools.

“…In recent years, there have been indications for use in laryngeal cancer with b-values of 50 and 1000 [9][10][11]. On the other hand, it is worth noting that there are also studies in the literature that use b-values of 0 and 800 [12,13].…”

PurposeTo evaluate the predictive capability of the apparent diffusion coefficient (ADC) at initial diagnosis in treatment-naive patients with laryngeal squamous cell carcinoma (LSCC) for the development of future metastases.Material and methodsMagnetic resonance images of patients with pathologically proven non-metastatic, treatment-naive LSCC were retrospectively evaluated. Follow-up positron emission tomography scans were assessed for the scanning of metastases.ResultsA total of 37 patients (32 males and 5 females) with a mean age of 62.8 ± 8.9 years were enrolled. Mean tumour volume and ADC were 4.8 ± 62 cm3 and 0.72 ± 0.51 × 10–3 mm2/s, respectively. Six local and 8 distant metastases were detected in a mean follow-up period of 17.5 ± 10.2 months. A significant association between ADC and the presence distant metastases (p = 0.046) and local metastases (p = 0.042) was found. The difference in mean ADC values between future metastatic and non-metastatic initial tumours was significant (p = 0.017).ConclusionsPre-treatment ADC values and volume of the initial tumour might provide early information about the development of future metastases in patients with LSCC in this series.
