Voice quality after surgery or radiotherapy for glottic T1 squamous cell carcinoma: Results of the VOQUAL study.

PURPOSE: Many series have compared voice quality after radiotherapy or surgery for cT1 glottic carcinoma. Different meta-analyses identify better results for radiotherapy while others do not identify any difference, some finally find a superiority of surgery. The purpose of this study was to compare the voice quality in the long term of patients who underwent transoral surgery versus exclusive irradiation for the treatment of cT1 glottic carcinoma. MATERIAL AND METHODS: The VOQUAL study was a pilot comparative multicenter cross-sectional study. The primary endpoint was the Voice Handicap Index comparison between two groups (radiotherapy or surgery). The voice assessment also consisted in the heteroevaluation of voice quality by the Grade, Roughness, Breathness, Asthenia, and Strain rating scale reported by Hirano. RESULTS: The study included 41 adult patients with cT1 carcinoma of the vocal cord treated by cordectomy or exclusive radiation in two oncologic centers. The median Voice Handicap Index value was 20 [8; 32.5] in the surgery group and 10 [4; 18.5] in the radiotherapy group. There was no statistically significant difference between the median values and the various components F, P and E of the questionnaire (P=0.1585). The median value of the numeric dysphonia Grade, Roughness, Breathness, Asthenia, and Strain scale was 2 [0; 5] in the surgery group and 2 [0.25; 3.75] in the radiotherapy group. There was no statistically significant difference between these values (P=0.78). CONCLUSION: Our study did not show any significant difference on the primary endpoints of Voice Handicap Index and Grade, Roughness, Breathness, Asthenia, and Strain scores. LEVEL OF EVIDENCE: III. CLINICAL TRIAL REGISTRATION: The VOQUAL study was registered on the ClinicalTrials.gov platform under the number NCT04447456, in July 2020.

Impact of the 2nd, 3rd and 4th waves of the COVID-19 pandemic on wait times in head and neck cancer: A retrospective study in a French expert center.

BACKGROUND: Treatment delay in head and neck cancer is a major problem, with impact on survival. The COVID-19 (coronavirus disease 2019) pandemic, evolving in waves around the world, caused diagnostic and therapeutic delays in certain cancers. The main objective of the present study was to analyze whether there was a change in wait times during three successive waves in our center. METHOD: This was a single-center retrospective study of patients with a first diagnosis of head and neck cancer. Three groups, corresponding to waves 2, 3 and 4, were compared to a control group corresponding to a pre-pandemic period. Study data comprised median times between first consultation and tumor board meeting (C1-TB) and between tumor board meeting and treatment (TB-T). The significance threshold was set at P<0.005. RESULTS: Ninety-six patients were included in the control group, and 154 in the "waves 2-3-4" group. There was no increase in C1-TB interval (respectively 35 and 26days, P=0.046) or TB-T interval (respectively 27 and 28days, P=0.723). CONCLUSION: Intervals between first consultation and tumor board meeting and between tumor board meeting and treatment did not increase during the 2nd, 3rd and 4th waves of COVID-19 in our center.

The first wave of COVID-19 did not cause longer wait times in head and neck cancer. Experience of a French expert center.

BACKGROUND: Head and neck cancers (HNC) have poor survival prognosis, as tumors are often diagnosed at advanced stages in patients consulting late. The first lockdown linked to the 1st wave of COVID-19 (Coronavirus Disease 2019) disrupted consultation schedules in France. OBJECTIVE: The principal aim of the present study was to analyze consultation wait time in HNC during and after lockdown, in our university expert oncology reference center, to disclose any increase in treatment wait time. METHODS: A single-center retrospective study included patients with a first diagnosis of HNC. Three groups were distinguished: "lockdown", "post-lockdown", and a "control" group (corresponding to a reference period 1 year earlier). Intervals between first oncologic consultation and multidisciplinary tumor board (FC-MTB) and between MTB and first treatment (MTB-T) were assessed. RESULTS: One hundred and seven patients were included in the control group, 60 in the lockdown group and 74 in the post-lockdown group. There was no increase in median FC-MTB interval (respectively 35, 29 and 28 days) between the lockdown and post-lockdown groups compared to the control group (respectively P=0.2298 and P=0.0153). Likewise, there was no increase in MTB-T interval (27, 20 and 26 days respectively) (P=0.4203). CONCLUSION: No increase in wait times was observed during the lockdown and post-lockdown periods in our center.

Match between therapeutic proposal in multidisciplinary tumor board and actual treatment in head and neck cancer.

OBJECTIVES: There are few published studies evaluating the quality and outcome of multidisciplinary tumor board (MDTB) decisions. The aim of the present study was to evaluate adherence to MDTB recommendations in head and neck cancer and to document reasons in case of discordance. MATERIAL AND METHODS: We included all patients with newly diagnosed head and neck cancer presented in our MDTB meetings between January 1st and December 31st, 2018, whatever the tumor site, histology type and TNM classification. MDTB recommendations were compared to actual treatment. Discordance was defined as treatment partially or entirely different from the treatment decision recorded in the MDTB minutes. RESULTS: Board decisions were made for 344 new patients. Complete treatment concordance rate was 91.6% (315/344 patients), with deviation in 29 patients. Reasons for deviation were complications of treatment in 10 cases, patient refusal in 8, and physician's decision in 4 cases. Five patients died before therapy initiation. Mean interval from board discussion to treatment was 21 days, and depended on type of treatment (range, 1 to 74 days). CONCLUSION: This study shows the importance of evaluating concordance between the protocol proposed in the MDTB and the treatment actually received, to identify factors for deviation and remedy them when possible.

Assessment and treatment of hypopharyngeal and cervical esophagus injury: Literature review.

Wounds and perforations of the upper gastrointestinal tract are serious and life-threatening. The hypopharynx and cervical esophagus, by their respective anatomical positions, are exposed to traumatic wounds, most often during diagnostic tests, but management such wounds remains a subject of discussion. The present article analyzes the current state of knowledge on epidemiology, etiologies, risk factors, diagnostic management, prognostic factors and available treatments.

Cystic form of cervical lymphadenopathy. Guidelines of the French Society of Otorhinolaryngology - Head and Neck Surgery (SFORL). Part 1: Diagnostic procedures for lymphadenopathy in case of cervical mass with cystic aspect.

OBJECTIVES: The authors present the guidelines of the French Society of Otorhinolaryngology - Head and Neck Surgery Society on diagnostic procedures for lymphadenopathy in case of a cervical mass with cystic aspect. METHODS: A multidisciplinary work-group was entrusted with a review of the scientific literature on the topic. Guidelines were drawn up, then read over by an editorial group independent of the work-group, and the final version was drawn up. Guidelines were graded as A, B, C or expert opinion, by decreasing level of evidence. RESULTS: In adults presenting a cystic cervical mass, it is recommended to suspect cervical lymphadenopathy: in order of decreasing frequency, cystic metastasis of head and neck squamous cell carcinoma, of undifferentiated nasopharyngeal carcinoma, and of thyroid papillary carcinoma (Grade C). On discovery of a cystic cervical mass on ultrasound, architectural elements indicating a lymph node and a thyroid nodule with signs of malignancy should be screened for, especially if the mass is located in levels III, IV or VI (Grade A). Malignant lymphadenopathy should be suspected in case of cervical mass with cystic component on CT (Grade B), but benign or malignant status cannot be diagnosed only on radiological data (CT or MRI) (Grade A), and 18-FDG PET-CT should be performed, particularly in case of inconclusive ultrasound-guided fine needle aspiration biopsy (Grade C).

Radiological assessment of mandibular invasion in squamous cell carcinoma of the oral cavity and oropharynx.

BACKGROUND: Preoperative assessment of mandibular bone invasion in squamous cell carcinoma of the oral cavity and oropharynx is crucial for optimizing bone resection. The principal aim of this study was to evaluate the diagnostic value of CT and MR imaging for the diagnosis of mandibular bone invasion compared to the histological reference. In addition, we assessed the survival impact of bone invasion. PATIENTS AND METHODS: A single-center retrospective study included all consecutive patients treated by mandibular bone interruption for squamous cell carcinoma of the oral cavity and/or oropharynx. RESULTS: Sixty-eight patients were included. Prevalence of bone invasion on histology was 43%. Sensitivity, specificity and positive and negative predictive value were respectively 70%, 71%, 66% and 76% for CT compared with histologic analysis, 83%, 50%, 59% and 78% for MRI, and 83%, 62% 62%, 83% for associated CT and MRI. The two tests showed good agreement, with kappa index 0.69 (95% CI, 0.49-0.89) (P<0.0001). There was no difference in overall survival (log-rank>0.70) between the groups with and without bone invasion. CONCLUSION: CT and MRI are complementary for preoperative assessment of mandibular bone invasion, be it cortical and/or medullary, and in some cases may allow mandibular bone-sparing.

Presence in head and neck cancer multidisciplinary team meeting: The patient's experience and satisfaction.

BACKGROUND: In oncology, multi-disciplinary team meetings improve overall survival and reduce time to treatment in head and neck cancer. Interestingly, no study has examined the experience of patients attending an MTM. The present study addressed two questions: Does the MTM cause anxiety/depression for patients who are present? Are patients satisfied at the end of the meeting? PATIENTS AND METHODS: The study included all patients attending an MTM, who agreed to participate in the study and who fully completed two questionnaires. The Hospital Anxiety and Depression Scale (HADS) and a satisfaction questionnaire were filled out at three time-points: T0 before MTM, T1 at end of MTM, and T2 1 month after MTM for the HADS; and T1 and T2 for the satisfaction questionnaire. RESULTS: There were no significant differences in the number of patients experiencing anxiety between T0 and T1 (P=0.6085), T0 and T2 (P=1) or T1 and T2 (P=1). Likewise, there were no significant differences in the number of patients in depression between T0 and T1 (P=0.9397), T0 and T2 (P=1) or T1 and T2 (P=1). Mean satisfaction was good (question 14 on the satisfaction questionnaire: 8.7/10 at T1 and 7.7/10 at T2), but with a significant decrease between T1 and T2 (P=0.0009: i.e.,<0.05). Percentage information remembered (question 12) significantly decreased between T1 (mean 86%, standard deviation 0.2, median 94%) and T2 (78%±0.2, median 81%) (P=0.03). Presence in the MTM did not appear to induce or increase anxiety or pre-existing depressive syndrome.

Atypical Lemierre syndrome.

INTRODUCTION: Lemierre syndrome is a complication of oropharyngeal infection and consists of a combination of internal jugular vein septic thrombophlebitis with septicaemia and distant septic emboli (mainly in the lungs). We describe an atypical case with facial vein and anterior jugular vein thrombophlebitis. CASE SUMMARY: A 34-year-old woman attended the emergency room with tonsillitis, left head and neck cellulitis, left facial vein thrombosis and lung abscesses. A diagnosis of atypical Lemierre syndrome was proposed and the patient was treated surgically (neck incision and tonsillectomy) and medically (antibiotics, hyperbaric oxygen therapy and anticoagulation) allowing cure without sequelae. DISCUSSION: Lemierre syndrome, a rare but serious complication requiring immediate treatment, should be investigated (by blood cultures and chest CT scan) in the presence of neck vein thrombosis complicating oropharyngeal infection.

The antitumor drug F14512 enhances cisplatin and ionizing radiation effects in head and neck squamous carcinoma cell lines.

BACKGROUND: Head and Neck Squamous Cell Carcinoma (HNSCC) is the sixth most common cancer worldwide. The treatment of advanced stages HNSCC is based on surgical treatment combined with radiotherapy and chemotherapy or concomitant chemo-radiotherapy. However, the 5-year survival remains poor for advanced stages HNSCC and the development of new targeted therapies is eagerly awaited. F14512 combines an epipodophyllotoxin core-targeting topoisomerase II with a spermine moiety introduced as a cell delivery vector. This spermine moiety facilitates selective uptake by tumor cells via the Polyamine Transport System (PTS) and reinforces topoisomerase II poisoning. Here we report the evaluation of F14512 toward HNSCC. MATERIALS AND METHODS: Four cell lines representative of head and neck cancer localizations were used: Fadu (pharynx), SQ20B (larynx), CAL33 and CAL27 (base of the tongue). PTS activity and specificity were evaluated by confocal microscopy and flow cytometry using the fluorescent probe F17073 which contains the same spermine moiety as F14512. Cytotoxicity, alone or in association with standard chemotherapeutic agents (cisplatin, 5FU), and radio-sensitizing effects were investigated using MTS and clonogenic assays, respectively. F14512 efficiency and PTS activity were also measured under hypoxic conditions (1% O2). RESULTS: In all 4 tested HNSCC lines, an active PTS was evidenced providing a specific and rapid transfer of spermine-coupled compounds into cell nuclei. Interestingly, F14512 presents a 1.6-11-fold higher cytotoxic effect than the reference compound etoposide (lacking the spermine chain). It appears also more cytotoxic than 5FU and cisplatin in all cell lines. Competition experiments with spermine confirmed the essential role of the PTS in the cell uptake and cytotoxicity of F14512. Hypoxia had almost no impact on the drug cytotoxicity. The combination of F14512 with cisplatin, but not 5FU, was found to be synergistic and, for the first time, we demonstrated the significant radio-sensitizing potential of F14512. CONCLUSION: The spermine moiety of F14512 confers a targeted effect and a much better efficacy than etoposide in HNSCC lines. The synergistic effect observed in association with cisplatin and radiotherapy augurs well for the potential development of F14512 in HNSCC.
