The impact of the multidisciplinary tumor board on head and neck cancer outcomes

Clinical trial participation, clinical care, and patient outcomes by practice setting: a real-world database analysis of patients with Chronic Lymphocytic Leukemia or Mantle Cell Lymphoma

OBJECTIVE

This study was designed to compare treatment patterns, clinical trial participation, and clinical outcomes among patients with small lymphocytic lymphoma/chronic lymphocytic leukemia (CLL) or Mantle cell lymphoma (MCL) by site of care.

METHODS

A nationwide electronic health record (EHR)-derived de-identified database was utilized for this study. Eligible patients were diagnosed with either CLL or MCL from 2013-2022 who received systemic therapy for their disease. Overall survival (OS) was analyzed using Kaplan Meier method, censoring patients without events at last observation in the database. Cox proportional hazards regression model was used to adjust for baseline covariates.

RESULTS

A total of 6,372 patients with CLL and 3,411 with MCL met eligibility criteria for this analysis; 13.9% and 22.2%, respectively, were treated in academic settings. Academic settings were associated with higher patient volume and were more likely to treat MCL with CAR-T, enroll patients with CLL or MCL to clinical trials, and care for patients who were younger, White, and for CLL with higher rates of del(17p) mutations (all p < 0.01). Survival was significantly longer among patients treated in academic vs community settings (median OS not reached vs 80.5 months for CLL; 95.6 vs 68.7 months for MCL from start of first-line therapy).

DISCUSSION

Patients who received care in academic settings differed from those treated in the community; care in academic settings was associated with significantly longer OS and higher trial participation. Further research is warranted to better understand the factors that may contribute to the observed outcomes.

Algorithm-based analysis of lymph node dissection strategies and survival outcomes in primary oral squamous cell carcinoma

Introduction

Recent advancements in treatment approaches for oral squamous cell carcinomas (OSCCs) necessitate a reevaluation of neck dissection techniques and their impact on patient outcomes and morbidity.

Methods

This retrospective study of 250 OSCC patients recruited between 2017-2022 examined the association between neck dissection techniques and survival metrics. Our cohort, drawn from a primary OSCC surgery population at our clinic, provided a rich dataset encompassing demographics, clinical parameters, and detailed surgical records. Two neck dissection techniques were analyzed: the Supraomohyoid Selective Neck Dissection (SND), which targets lymph nodes at Levels I-III, and Other Dissections (OD), which involve a more extensive extraction including Levels IV and V. Kaplan-Meier survival curves and Cox proportional hazards models assessed the influence of lymph node dissection on postoperative outcomes.

Results

Findings indicated that each additional lymph node removed was associated with a 0.289-day increase in hospitalization (p = 0.002), yet no significant link was found between dissection techniques or total lymph node extraction count and survival metrics. Levels I to III emerged as critical areas with the highest likelihood of yielding tumor-positive lymph nodes, emphasizing the significance of these levels.

Discussion

The study suggests that more extensive dissection does not necessarily confer survival benefits, highlighting the importance of strategic surgical focus and the potential for tailored interventions that prioritize disease-specific lymph node levels to optimize patient recovery and prognosis.

International multispecialty expert physician preoperative identification of extranodal extension in patients with oropharyngeal cancer using computed tomography: Prospective blinded human inter-observer performance evaluation

BACKGROUND

Pathologic extranodal extension (pENE) is a crucial prognostic factor in oropharyngeal cancer (OPC), but determining pENE from imaging has high inter-observer variability. The role of clinician specialty in the accuracy of imaging-detected extranodal extension (iENE) remains unclear. The purpose of this study is to assess the influence of clinician specialty on the accuracy of preoperative iENE detection in human papillomavirus (HPV)-positive OPC using computed tomography (CT) imaging.

METHODS

This prospective observational study evaluated pretherapy CT images from 24 HPV-positive OPC patients (30 scans, including duplicates). Thirty-four expert observers (11 radiologists, 12 surgeons, 11 radiation oncologists) assessed iENE and reported radiologic criteria and confidence. Ground-truth pENE status was confirmed pathologically. Accuracy, sensitivity, specificity, area under the receiver operating characteristic curve, and Brier scores were compared across specialties. Logistic regression determined significant predictors of pENE, whereas Fleiss' kappa measured interobserver agreement.

RESULTS

Median accuracy was 0.57 (95% CI, 0.39-0.73), with no specialty showing performance beyond chance (median area under the receiver operating characteristic curve, 0.64). Minor differences were noted: surgeons had lower Brier scores (0.26 vs. 0.33, p < .01) and higher sensitivity (0.69 vs. 0.48) compared to radiologists and oncologists. Predictive signs included indistinct capsular contour and nodal necrosis. Interobserver agreement was weak (κ < 0.6).

CONCLUSIONS

Diagnostic performance for iENE on CT in HPV-positive OPC remains poor across specialties, with high variability and low accuracy. These findings highlight the need for automated systems or improved imaging methods to enhance iENE assessments.

Impact of Preoperative Multidisciplinary Conference on Head and Neck Reconstruction Outcomes

INTRODUCTION

Head and neck oncologic resections with microvascular reconstruction are lengthy and complex procedures with inefficiencies in the operating room (OR) associated with increased complications and higher costs. Multidisciplinary care has become increasingly used to provide improved care for complex patients; however, the potential role of this has not yet been studied in head and neck microvascular free flap procedures.

METHODS

Patients between 2016 and 2022 treated before and after implementation of the conference were included. Primary outcome was total procedure time (TPT). Demographics, operative details, and postoperative complications were also collected.

RESULTS

233 patients were included in the preconference group and 330 in the post-conference group. Preconference mean (SD) age was 61.6 (12) years versus 62.9 (12) years in the post-conference group. The post-conference group was associated with shorter mean (SD) TPT (629 [117] vs. 719 [134] minutes), less mean (SD) estimated blood loss (ESD) (230 [201] mL vs. 306 [211] mL), fewer prolonged lCU stays (>1 day), and fewer returns to the operating room (RTOR). The post-conference group was associated with TPT ≤9 h (p < 0.001) on multivariate analysis. Factors associated with TPT greater than 9 h include history of head and neck radiation (p = 0.003), bony reconstruction (p = 0.05), stage IVa (p = 0.009), and stage IVb cancer (p < 0.001).

CONCLUSIONS

Implementation of the multidisciplinary conference in head and neck surgery was associated with reduced TPT and reduced OR return. Our study suggests preoperative planning conferences may improve surgical efficiency and outcomes in head and neck oncologic resections with microvascular free flap reconstruction.

Recommendations for the management of cutaneous squamous cell carcinoma: a systematic multidisciplinary Delphi consensus approach

BACKGROUND

There are gaps and unanswered questions in clinical guidelines regarding several aspects of the management of patients with cutaneous squamous cell carcinoma (cSCC).

METHODS

A scientific committee of ten cSCC specialists in Spain (dermatology, medical oncology, oral and maxillofacial surgery, plastic surgery, and radiotherapy) used ADAPTE methodology to develop recommendations by: (i) identifying clinical questions not fully answered by clinical practice guidelines; (ii) systematically reviewing the literature (published between November 2017 and July 2023 in PubMed and the Cochrane database) and grading the evidence (using Oxford levels); (iii) developing recommendations and assessing those with no consensus among the scientific committee or with evidence level 3-5 or strength of recommendation under C or D in a two-round Delphi method; and (iv) developing the final recommendations in the form of answers to key clinical questions, grading the strength of recommendation. An external group of 32 experts plus the members of the committee participated in both Delphi rounds, evaluating the appropriateness and need of the recommendations.

RESULTS

Initially, 33 recommendations were made for 26 questions; 19 recommendations were evaluated with the Delphi method. All 19 recommendations were deemed appropriate and necessary. A total of 27 final recommendations were made, concerning initial patient management, treatment of the primary tumour, management of advanced disease, specific populations, supportive and palliative care, and follow-up.

CONCLUSION

We developed 27 recommendations that answer clinical questions on the management of patients with cSCC, providing guidance on aspects that are unclear in clinical guidelines or on which guidelines differ.

A bright future for multidisciplinary approach to cancer care in the setting of limited resource

We report a case of alveolar rhabdomyosarcoma of the infratemporal region in a female child. An 8year old female was diagnosed with alveolar rhabdomyosarcoma 10 years ago. A computed tomography (CT) scan showed large mass in the right pterygopalatine fossa extending into the buccal, masticator and parapharyngeal spaces with involvement of the pterygoid and masseter muscles. Several multidisciplinary discussions were held concerning the case to determine the best treatment strategy. Child received neoadjuvant chemotherapy followed by radiotherapy. Six months post radiotherapy, CT scan reported a residual lesion for which multiple biopsies showed no residual tumor. Patient is doing well 10 years after treatment with no evidence of recurrence, Notably, this was the first case discussed at the inception of the pediatric multidisciplinary tumor board.

Integrating MDT Tumor Board Shadowing into the Undergraduate Medical Curriculum: Perspective of Medical Students

Site-specific multidisciplinary team (MDT) tumor boards are valuable resources for medical students, enabling them to familiarize themselves with the latest evidence-based cancer management strategies and observe effective teamwork in action. In this study, we looked at the awareness and perceptions of medical students about incorporating MDT tumor boards in the medical curriculum. A cross-sectional study was conducted among medical students from year 1 to year 5 at the Aga Khan University after exemption from ethical review committee. A 20-item self-administered questionnaire was used to evaluate the awareness and perceptions of medical students regarding MDT tumor boards. A total of 285 medical students participated in this study, with their mean age (± standard deviation) being 21.91 ± 1.67 years. A majority of 183 (64.2%) had no prior knowledge of the existence of a site-specific MDT tumor board for cancer management. Of the 285 students, 252 (88.4%) demonstrated sufficient awareness of the effectiveness of MDT tumor boards; similarly, 232 (81.4%) responded positively to the idea of mandatory tumor board rotations being incorporated into the undergraduate curriculum. No significant association was found between the student's year of study (χ2 = 6.03, p = 0.20) or gender (χ2 = 35, p = 0.84) and their perceptions of the effectiveness of MDT tumor boards. However, it was found that students who had prior knowledge of their existence had a stronger association with sufficient awareness (χ2 = 4.2, p = 0.04). The results indicate that while the majority of the medical students have no prior attendance or knowledge regarding MDT tumor boards, there is an overwhelming willingness among students to incorporate them into the medical curriculum.

Osteoradionecrosis incidence in pre-radiation teeth extractions: A prospective study

AIMS

To evaluate osteoradionecrosis (ORN) incidence in a cohort of patients undergoing tooth extraction (TE) before radiotherapy (RT) for head and neck cancers.

METHODS

The study protocol was approved by the Ethics Committee of Università Cattolica del Sacro Cuore (ID-2132) and registered at clinicaltrials.gov (ID: NCT04009161). TE was performed in case of signs of pericoronitis, periapical lesions, restorative impossibility, severe periodontitis. ORN was defined as exposed bone at an unhealed post-extraction socket in the absence of oncological recurrence. The RT plans were reviewed, and each post-extractive socket was contoured to calculate the received radiation dose.

RESULTS

In total, 156 patients with 610 TE were enrolled. The mean follow-up was 567 days. ORN was diagnosed in four patients (2.6% of patients and 0.7% of TE). Need for osteotomy and radiation dose at the extraction site were associated with ORN (OR for osteotomy: 21.9, 95% CI: 2.17-222.2, p = 0.009; OR for RT dose: 1.1, 95% CI: 1-1.15, p = 0.05).

CONCLUSIONS

TE appears to be a significant risk factor for ORN, particularly when osteotomy is required, and post-extraction sockets receive a high RT dosage. This study proposes a decision-making algorithm for TE and outlines a straightforward surgical protocol.

Enhanced head and neck radiotherapy target definition through multidisciplinary delineation and peer review: A prospective single-center study

This study evaluates the benefit of weekly delineation and peer review by a multidisciplinary team (MDT) of radiation oncologists (ROs), radiologists (RXs), and nuclear medicine (NM) physicians in defining primary and lymph node tumor volumes (GTVp and GTVn) for head and neck cancer (HNC) radiotherapy. This study includes 30 consecutive HNC patients referred for definitive curative (chemo)-radiotherapy. Imaging data including head and neck MRI, [18F]-FDG-PET and CT scan were evaluated by the MDT. The RO identified the 'undeniable' tumor as GTVp_core and determined GTVp_max, representing the maximum tumoral volume. The MDT delineation (MDT-D) by RX and NM physicians outlined their respective primary GTVs (GTVp_RX and GTVp_NM). During the MDT meeting (MDT-M), these contours were discussed to reach a consensus on the final primary GTV (GTVp_final). In the comparative analysis of various GTVp delineations, we performed descriptive statistics and assessed two MDT-M factors: 1) the added value of MDT-M, which includes the section of GTVp_final outside GTVp_core but within GTVp_RX or GTVp_NM, and 2) the part of GTVp_final that deviates from GTVp_max, representing the area missed by the RO. For GTVn, discussions evaluated lymph node extent and malignancy, documenting findings and the frequency of disagreements. The average GTVp core and max volumes were 19.5 cc (range: 0.4-90.1) and 22.1 cc (range: 0.8-106.2), respectively. Compared to GTVp_core, MDT-D to GTVp_final added an average of 3.3 cc (range: 0-25.6) and spared an average of 1.3 cc (0-15.6). Compared to GTVp_max, MDT-D and -M added an average of 2.7 cc (range: 0-20.3) and removed 2.3 cc (0-21.3). The most frequent GTVn discussions included morphologically suspicious nodes not fixing on [18F]-FDG-PET and small [18F]-FDG-PET negative retropharyngeal lymph nodes. Multidisciplinary review of target contours in HNC is essential for accurate treatment planning, ensuring precise tumor and lymph node delineation, potentially improving local control and reducing toxicity.

Patient management with Head and Neck tumors-A nationwide data collection in oral and maxillofacial surgery

INTRODUCTION

This study analyzed oncologic patient management from initial tumor diagnosis to tumor follow-up in oral and maxillofacial surgery (OMFS) in Germany.

MATERIAL AND METHODS

A dynamic online questionnaire with a total of 44 questions was used to generate general and specific data regarding oncologic patient management with head and neck malignancies, supportive care, and (pre-) rehabilitation from initial tumor diagnosis to tumor follow-up and head and neck cancer center (HNCC) structures in OMFS in Germany. The questionnaire was sent to 81 OMFS departments affiliated with the German-Austrian-Swiss Working Group for Tumors of the Jaw and Facial Region (DÖSAK) and the German Association of Oral and Maxillofacial Surgery (DGMKG). Data analysis was conducted descriptively.

RESULTS

Forty-eight OMFS departments participated (response rate 59.26%), of which 36/48 (75%) were certified HNCC. 28/34 (82.4%) reported subjective improvements in oncologic care, most often interdisciplinary collaboration (21/33, 63.64%) and clinic structure changes (21/34, 61.76%). Nearly all OMFS departments present patients in multidisciplinary tumor boards (45/46, 97.83%) and aim for osseous reconstruction post-tumor resection (43/44, 97.73%). Significant discrepancies regarding the frequency of masticatory-functional dental rehabilitation following osseous reconstruction were observed. Before oncologic therapy, patients are offered various supportive services, mostly psychotherapy and psycho-oncological support (24/26, 92.31%). Post-therapy, speech therapy (43/43, 100%), physiotherapy (40/43, 93.02%), lymphatic drainage, and follow-up rehabilitation (39/43, 90.7%, respectively) are most often offered. 17/43 (39.53%) have oncological nursing staff. 36/40 (90%) manage patients and side effects during adjuvant therapy, while 5/41 (12.2%) provide proprietary palliative care. 36/41 (87.8%) offer counseling to patients and families.

CONCLUSION

Oncologic patient care in OMFS is highly standardized and potentially attributable to many certified HNCCs in Germany. Certain treatment aspects are handled differently, possibly due to institution-specific reasons.

CLINICAL RELEVANCE

The high homogeneity in treatment protocols reflects the widespread high and comparable treatment quality of head and neck malignancies in OMFS in Germany.

International Multi-Specialty Expert Physician Preoperative Identification of Extranodal Extension n Oropharyngeal Cancer Patients using Computed Tomography: Prospective Blinded Human Inter-Observer Performance Evaluation

Importance

Extranodal extension (pENE) is a critical prognostic factor in oropharyngeal cancer (OPC) that drives therapeutic disposition. Determination of pENE from radiological imaging has been associated with high inter-observer variability. However, the impact of clinician specialty on human observer performance of imaging-detected extranodal extension (iENE) remains poorly understood.

Objective

To characterize the impact of clinician specialty on the accuracy of pre-operative iENE in human papillomavirus-positive (HPV+) OPC using computed tomography (CT) images.

Design Setting and Participants

This prospective observational human performance study analyzed pre-therapy CT images from 24 HPV+ OPC patients, with duplication of 6 scans (n=30) of which 21 were pathologically confirmed pENE. Thirty-four expert observers, including 11 radiologists, 12 surgeons, and 11 radiation oncologists, independently assessed these scans for iENE and reported human-detected radiologic criteria and observer confidence.

Main Outcomes and Measures

The primary outcomes included accuracy, sensitivity, specificity, area under the receiver operating characteristic curve (AUC), and Brier score for each physician, compared to ground-truth pENE. The significance of radiographic signs for prediction of pENE were determined through logistic regression analysis. Fleiss' kappa measured interobserver agreement, and Hanley-MacNeil AUC discrimination testing.

Results

Median accuracy across all specialties was 0.57 (95%CI 0.39 to 0.73), with no specialty showing discriminate performance greater than random estimation (median AUC 0.64, 95%CI 0.44 to 0.83). Significant differences between radiologists and surgeons in Brier scores (0.33 vs. 0.26, p < 0.01), radiation oncologists and surgeons in sensitivity (0.48 vs. 0.69, p > 0.1), and radiation oncologists and radiologists/surgeons in specificity (0.89 vs. 0.56, p > 0.1). Indistinct capsular contour and nodal necrosis were significant predictors of correct pENE status among all specialties. Interobserver agreement was weak for all the radiographic criteria, regardless of specialty (κ<0.6).

Conclusions and Relevance

Multiobserver testing shows physician discrimination of HPV+OPC pENE on pre-operative CT remains non-different than blind guessing, with high interrater variability and low diagnostic accuracy, regardless of clinician specialty. While minor differences in diagnostic performance among specialties are noted, they do not significantly affect the overall poor agreement and discrimination rates observed. The findings underscore the need for further research into automated detection systems or enhanced imaging techniques to improve the accuracy and reliability of iENE assessments in clinical practice.

Optimising head and neck cancer patient management: the crucial contributions of multidisciplinary tumour board decision-making

Introduction

Squamous cell carcinoma (SCC) of the head and neck is a great burden globally, which is being tackled through treatment options of surgery, radiation therapy, chemotherapy, or a combination of these, to avoid disease-related mortality. Multidisciplinary tumour boards play a pivotal role in customising and deciding management plan based on clinical aspects. The objective of the study is to determine the concordance of opinion between the treatment plan of a primary physician and board members.

Material and methods

This is a retrospective cross-sectional study that includes 137 head and neck carcinoma cases. They were discussed in the multidisciplinary tumour board meeting and were reviewed; all demographics were analysed including the tumour staging and the decisions of the primary physician was compared with those of the board. To check the concordance between primary surgeon plans or after board discussion Kappa agreement test was used.

Results

Total of 137 patients were included in the study out of which 63 cases were pre-treatment and 74 cases were post-treatment, i.e., surgically treated cases, with the distribution being 46% and 54%, respectively. Most cases, totaling 120, were SCC, accounting for 80% of the total cases. Among the pre-treatment cases, T4a and N0 were the most common categories, with 29 and 40 cases, respectively. Similarly, in post-treatment cases, the majority fell into the T4a and N1 categories, with 29 and 38 cases, respectively. When comparing the primary surgeon's plan with the tumour board meeting decision, the agreement showed a value of 0.273, indicating a slight level of agreement between the two entities.

Conclusion

Our data indicates that the multidisciplinary head and neck tumour board may have influenced the treatment plans of the primary surgeon, in approximately one in two patients (43.06%).

The impact of multidisciplinary cancer conferences on overall survival: a meta-analysis

BACKGROUND

Multidisciplinary cancer conferences consist of regular meetings between diverse specialists working together to share clinical decision making in cancer care. The aim of this study was to systematically review and meta-analyze the effect of multidisciplinary cancer conference intervention on the overall survival of patients with cancer.

METHODS

A systematic literature search was conducted on Ovid MEDLINE, EMBASE, and the Cochrane Controlled Register of Trials for studies published up to July 2023. Studies reporting on the impact of multidisciplinary cancer conferences on patient overall survival were included. A standard random-effects model with the inverse variance-weighted approach was used to estimate the pooled hazard ratio of mortality (multidisciplinary cancer conference vs non-multidisciplinary cancer conference) across studies, and the heterogeneity was assessed by I2. Publication bias was examined using funnel plots and the Egger test.

RESULTS

A total of 134 287 patients with cancer from 59 studies were included in our analysis, with 48 467 managed by multidisciplinary cancer conferences and 85 820 in the control arm. Across all cancer types, patients managed by multidisciplinary cancer conferences had an increased overall survival compared with control patients (hazard ratio = 0.67, 95% confidence interval = 0.62 to 0.71, I2 = 84%). Median survival time was 30.2 months in the multidisciplinary cancer conference group and 19.0 months in the control group. In subgroup analysis, a positive effect of the multidisciplinary cancer conference intervention on overall survival was found in breast, colorectal, esophageal, hematologic, hepatocellular, lung, pancreatic, and head and neck cancer.

CONCLUSIONS

Overall, our meta-analysis found a significant positive effect of multidisciplinary cancer conferences compared with controls. Further studies are needed to establish nuanced guidelines when optimizing multidisciplinary cancer conference integration for treating diverse patient populations.

Sodium-hyaluronate mouthwash on radiotherapy-induced xerostomia: a randomised clinical trial

INTRODUCTION

Radiotherapy-induced xerostomia (RIX) is one of the most common adverse effects of radiotherapy (RT) in head and neck cancer patients (HNC) and a major determinant of survivors' quality of life. The primary objective was to evaluate the reduction of patients' xerostomia symptoms after the utilisation of a sodium-hyaluronate mouthwash compared to a placebo solution. The secondary objectives were to evaluate the improvement of quality of life and to evaluate the patients' satisfaction.

METHODS

The protocol was approved by the ethical committee (Ref. 50,053/19) and registered at ClinicalTrials.gov (ID: NCT05103124). The study was a double-blind randomised clinical trial (RCT) with a crossover design and was conducted at the Fondazione Policlinico Universitario A. Gemelli, Rome.

RESULTS

Thirty-two patients completed the study protocol. Lower values of the modified Xerostomia Questionnaire (XQ) were retrieved when comparing the baseline scores to the ones after the treatment, when compared with placebo (Mann-Whitney U test = 0.01); higher values of patients' satisfaction (Likert scale) and modified XQ were retrieved for the sodium-hyaluronate mouthwash (Mann-Whitney U test = 0.001).

CONCLUSIONS

This RCT highlights the advantages of treating RIX with the sodium-hyaluronate mouthwash since it seems to be clinically effective in reducing its symptoms, without any reported adverse events.

Late laryngeal dysfunction in head and neck cancer survivors

Objectives

Head and neck cancer (HNC) survivorship issues are areas of increasing research interest. Laryngeal dysfunction in HNC patients is particularly important given the importance of the larynx in voice, swallowing, and airway protection. The objective of our study is to characterize late laryngeal dysfunction in a cohort of long-term HNC survivors.

Methods

HNC survivors who were at least 2 years post-treatment were recruited prospectively for standard collection of videolaryngoscopy findings, videofluoroscopic swallowing studies, and assessment of clinical outcomes. Descriptive statistics were performed and clinical presentation and outcomes were compared between survivors >10 years and <10 years post-treatment. Additional factor analysis to correlate clinical outcomes with clinical variables was performed.

Results

Thirty participants were analyzed with a mean age of 66 years. The majority were male (80%) patients treated for oropharyngeal squamous cell carcinoma (67%). Within the cohort, 43% underwent primary chemoradiation therapy and had 13% radiation alone. Common presenting symptoms included swallowing dysfunction (83%), voice change (67%), and chronic cough (17%). Laryngeal findings on video laryngoscopy include vocal fold motion abnormalities (VFMA) in over half of participants (61%) and mucosal changes in 20%. A weak correlation was found between time since treatment and laryngeal dysfunction (r = .182, p = .34), and no correlation was found between age, sex, time since treatment, or primary site and the presence or absence of VFMA, G-tube status, or tracheostomy-tube status.

Conclusion

Late laryngeal dysfunction in HNC survivors contributes to significant morbidity, is difficult to treat, and remains static decades after treatment for their original cancer.

Lay Summary

The voice-box, or the larynx, plays an important role in voice, swallowing and airway protection. It is particularly vulnerable to radiation-related damage and changes. This study demonstrates the sequelae of long-term damage of the larynx in head and cancer survivors.

Virtual Tumor Boards for Remote Learning in Head and Neck Surgical Oncology

Importance

In addition to their patient management value, multidisciplinary tumor boards have been recognized as effective learning tools. However, the value of using a virtual tumor board as a learning tool for head and neck surgical oncology fellows has not been studied.

Objective

To describe the structure and content of the American Head and Neck Society (AHNS) Virtual Tumor Board and assess its educational value as perceived by attendees.

Design, Setting, and Participants

All sessions of the AHNS Virtual Tumor Board from April 8, 2020, to June 1, 2022, were reviewed. Topics, presenters, participants, and viewership data were collected as of October 15, 2022, from session recordings posted to an online video sharing and social media platform. Additionally, an anonymous, 14-question online survey was designed to elicit feedback from head and neck surgery trainees on virtual tumor board engagement, strengths, and weaknesses. The survey was electronically distributed in June and July 2022 to the 101 fellows enrolled in AHNS-accredited programs between July 1, 2020, and June 30, 2022.

Main Outcomes and Measures

The primary aim was to tabulate online viewership of the sessions. The secondary aim was to qualitatively assess the experience of head and neck trainees with the AHNS Virtual Tumor Board using a survey.

Results

Forty-two sessions of the virtual tumor board were held between April 8, 2020, and June 1, 2022. Almost all sessions (41 [98%]) were case based. One hundred and sixteen cases were presented, representing 2 to 3 cases per session, by 75 unique faculty members. Each session was viewed a mean of 217 times (range, 64-2216 views). In the 2021 to 2022 academic year, a mean of 60 viewers (range, 30-92 viewers) attended each live session. In all, 29 survey responses were collected from 101 fellows in AHNS-accredited programs (29% response rate). Most respondents felt the format allowed for excellent teaching (18 of 26 respondents [69%]) and discussion (19 of 26 respondents [73%]). Most respondents (22 of 29 respondents [76%]) believed that practicing head and neck surgeons would benefit from the sessions.

Conclusions and Relevance

This survey study found that the AHNS Virtual Tumor Board was well-attended and well-reviewed by head and neck surgical oncology trainees. The virtual tumor board format could be used as model of remote learning for other organizations.

Impact of independent multidisciplinary work on the survival rate of stage 3 and 4 nasopharyngeal cancer in Indonesia: a retrospective cohort study

Background

The utilization of a multidisciplinary team (MDT) strategy is a beneficial approach in integrating the knowledge and proficiencies of various fields to produce thorough and advantageous cancer treatment plans for patients. Nevertheless, MDT has yet to be widely adopted in Indonesia. In this study, the authors examined an early form of MDT in Indonesia that does not involve dedicated meetings, referred as independent multidisciplinary work (IMW). The objective is to investigate the differences in survival rates of nasopharyngeal cancer (NPC) patients who underwent treatment with and without IMW.

Materials and methods

This study has a retrospective cohort design. Data were collected from the medical records of newly diagnosed stage 3 and 4 NPC patients between 2016 and 2018. The subjects were divided into two groups: the IMW group and the non-IMW group. The primary end point of the study is overall survival rate between the two groups. Kaplan-Meier survival analysis, log-rank test, and cox proportional hazard analysis were used for statistical analysis.

Results

This study included a total of 124 patients with NPC, 81 patients in the IMW group and 43 patients in the non-IMW group. At the end of the 36-month follow-up period, the median survival of the IMW group was not reached, while in the non-IMW, it was 12 months [95% confidence intervals (95% CI), 8.78-15.22], hazard ratio (HR): 0.47 (95% CI, 0.28-0.78; P<0.01). The 1-year survival rate was 66.7% in the IMW group versus 46.5% in the non-IMW group (HR=0.7, 95% CI 0.49-0.99; P=0.03); the 2-year survival rate was 40.7% in the IMW group versus 16.3% in the non-IMW group (HR=0.4, 95% CI 0.19-0.83; P<0.01). Daniel Rizky, Vina Yunarvika, and Yasjudan Rastrama Putra, these authors contributed equally to this work. In the multivariate analysis, the IMW approach, ECOG (The Eastern Cooperative Oncology Group) status, distant metastasis, and treatment approach were significantly associated with survival outcome.

Conclusion

The use of IMW approach in the treatment of NPC was associated with a better survival outcome compared to non-IMW treatment.

Importance of interdisciplinarity in modern oncology: results of a national intergroup survey of the Young Oncologists United (YOU)

PURPOSE

Modern, personalized treatment concepts in oncology require an interdisciplinary and multiprofessional collaboration. In addition to its relevance in patient care, interdisciplinary collaboration is also becoming increasingly important in clinical research as well as medical education and resident training in oncology.

METHODS

Between November 2021 and March 2022, an online survey was conducted among German early career research groups, represented by Young Oncologists United (YOU). The aim was to identify the status and need for interdisciplinarity at clinic, educational, and research levels.

RESULTS

A total of 294 participants completed the questionnaire in full. 90.7% of the respondents fully or predominantly agreed with the statement that interdisciplinary work plays a major role in their daily clinical work. 78.9% wished for more interdisciplinary collaboration. Of the 49.7% of participants who have never participated in an interdisciplinary research project, 80.1% said they would like to participate in such a study project in the future. Lack of time resources, too much organizational effort, and possible political conflicts between institutions were identified as factors that make practical implementation difficult. 74.1% declared their willingness to become active in an oncology early career research group.

CONCLUSION

Interdisciplinary collaboration has become increasingly important in oncology. Networks that span different disciplines could help to promote interdisciplinary research projects among young scientists and improve exchange in professional practice and education with the implication of improved patient care.

Multidisciplinary tumor board for head and neck cancer from the perspective of medical oncologists-optimizing its effectiveness

Head and neck cancer (HNC) treatment is becoming increasingly multidisciplinary, and patient characteristics vary. Therefore, a multidisciplinary tumor board (MTB) is essential in clinical practice. This review provides insights into the benefits and tips for improving head and neck MTB from the perspective of medical oncologists. The MTB is a platform to discuss the optimal application of the standard of care to each case, reach a consensus, and establish a recommendation to support patients' decision-making. A productive and educational MTB also provides an opportunity to share information on ongoing clinical trials with physicians. Case presentations should be systematic to discuss all new and challenging cases before, during, and after the treatment. Human resource development, particularly of head and neck medical oncologists, is crucial. The type of multidisciplinary network between medical staff and the extent of patient intervention differs among MTB teams. Subsequently, a virtual MTB can establish a medical network between institutions that will contribute to the equalization and centralization of head and neck oncologic care.

Building Team Medicine in the Management of CNS Metastases

CNS metastases are often terminal for cancer patients and occur at an approximately 10-fold higher rate than primary CNS tumors. The incidence of these tumors is approximately 70,000-400,000 cases annually in the US. Advances that have occurred over the past two decades have led to more personalized treatment approaches. Newer surgical and radiation techniques, as well as targeted and immune therapies, have enanled patient to live longer, thus increasing the risk for the development of CNS, brain, and leptomeningeal metastases (BM and LM). Patients who develop CNS metastases have often been heavily treated, and options for future treatment could best be addressed by multidisciplinary teams. Studies have indicated that patients with brain metastases have improved survival outcomes when cared for in high-volume academic institutions using multidisciplinary teams. This manuscript discusses a multidisciplinary approach for both parenchymal brain metastases as well as leptomeningeal metastases implemented in three academic institutions. Additionally, with the increasing development of healthcare systems, we discuss optimizing the management of CNS metastases across healthcare systems and integrating basic and translational science into our clinical care to further improve outcomes. This paper summarizes the existing therapeutic approaches to the treatment of BM and LM and discusses novel and emerging approaches to optimizing access to neuro-oncologic care while simultaneously integrating multidisciplinary teams in the care of patients with BM and LM.

Is Systemic Immunosuppression a Risk Factor for Oral Cancer? A Systematic Review and Meta-Analysis

Even if the relationship between immunosuppression and increased incidence of systemic cancers is well known, there is less awareness about the risk of developing oral cancer in immunosuppressed patients. The aim of this review was to evaluate the association between immunosuppression and the development of oral cancer. Two authors independently and, in duplicate, conducted a systematic literature review of international journals and electronic databases (MEDLINE via OVID, Scopus, and Web of Science) from their inception to 28 April 2023. The assessment of risk of bias and overall quality of evidence was performed using the Newcastle-Ottawa Scale and GRADE system. A total of 2843 articles was identified, of which 44 met the inclusion criteria and were included in either the qualitative or quantitative analysis. The methodological quality of the included studies was generally high or moderate. The quantitative analysis of the studies revealed that immunosuppression should be considered a risk factor for the development of oral cancer, with a percentage of increased risk ranging from 0.2% to 1% (95% CI: 0.2% to 1.4%). In conclusion, the results suggest that a constant and accurate follow-up should be reserved for all immunosuppressed patients as a crucial strategy to intercept lesions that have an increased potential to evolve into oral cancer.

Adherence to Multidisciplinary Tumor Board Recommendations in Patients With Curable Esophageal and Gastric Cancers

BACKGROUND

Multidisciplinary tumor board (MDT) discussion is standard practice in the management of Upper Gastrointestinal (UGI) cancers. However, poor adherence to MDT recommendations may account for the lack of improved oncological outcomes with MDTs. We aim to quantify adherence rates and compare outcomes between adherent and non-adherent patients.

METHODS

We included all patients with potentially curable primary UGI carcinomas who were discussed at UGI MDT from 2017 to 2018. MDT recommendations were compared to actual treatment received. Oncological and survival outcomes were compared between both groups.

RESULTS

Amongst 153 patients, 64 (41.8%) were non-adherent to MDT recommendations. Reasons for non-adherence were patient refusal (50.0%), treatment-related complications (31.3%), disease factors (17.2%) and clinician decision (1.56%). Univariate analysis showed that non-adherent patients were older (71.6 vs 65.2 years, p < 0.001), with higher clinical stage at point of diagnosis (p = 0.028), pathological stage after resection (p < 0.001) and were more likely to be recommended for multimodal therapy. No significant factors were associated with non-adherence at multivariate analysis. Non-adherent patients had worse median overall survival (19.5 months) compared to adherent patients (not reached at follow-up) with both unmatched and propensity-score matched analysis. Patients who received only part of the intended adjuvant chemotherapy course had worse median overall survival and disease-free survival compared to patients who completed or did not initiate adjuvant chemotherapy.

CONCLUSIONS

Non-adherence to MDT recommendations was associated with advanced age and tumor stage, and potentially contributes to the worse oncological outcomes in a group of patients already predisposed to poor outcomes.

Using Brain Tumor MRI Structured Reporting to Quantify the Impact of Imaging on Brain Tumor Boards

Multidisciplinary tumor boards (TB) are an essential part of brain tumor care, but quantifying the impact of imaging on patient management is challenging due to treatment complexity and a lack of quantitative outcome measures. This work uses a structured reporting system for classifying brain tumor MRIs, the brain tumor reporting and data system (BT-RADS), in a TB setting to prospectively assess the impact of imaging review on patient management. Published criteria were used to prospectively assign three separate BT-RADS scores (an initial radiology report, secondary TB presenter review, and TB consensus) to brain MRIs reviewed at an adult brain TB. Clinical recommendations at TB were noted and management changes within 90 days after TB were determined by chart review. In total, 212 MRIs in 130 patients (median age = 57 years) were reviewed. Agreement was 82.2% between report and presenter, 79.0% between report and consensus, and 90.1% between presenter and consensus. Rates of management change increased with increasing BT-RADS scores (0-3.1%, 1a-0%, 1b-66.7%, 2-8.3%, 3a-38.5%, 3b-55.9, 3c-92.0%, and 4-95.6%). Of 184 (86.8%) cases with clinical follow-up within 90 days after the tumor board, 155 (84.2%) of the recommendations were implemented. Structured scoring of MRIs provides a quantitative way to assess rates of agreement interpretation alongside how often management changes are recommended and implemented in a TB setting.

Exophytic Squamous Cell Carcinoma of the Scalp: A Case Report

Squamous cell carcinoma (SCC) is the second-most common clinical presentation of non-melanoma skin cancer. Despite its prevalence, the rate of growth and development of SCC lesions is low. We present a case report of an exophytic SCC of the midline scalp. Over approximately 18 months, the exophytic portion of this lesion grew to a size of 8.5 x 7 cm due to the fact that the patient did not seek medical attention. The patient suffered from many predisposing factors including active smoking status, type II diabetes, and significant previous sun exposure. In addition to these predisposing factors, the patient did not have comprehensive health insurance to cover outpatient medical care. This case highlights the importance of early intervention in the management of head and neck skin cancers and the negative impact of delayed treatment.

Virtual versus in-person multidisciplinary musculoskeletal tumor conferences in times of COVID-19

Introduction

Multidisciplinary tumor conferences are a fundamental component in the treatment of oncological patients. The COVID-19 pandemic and its resulting social distancing restrictions offered the opportunity to compare in-person to virtual multidisciplinary tumor conferences.

Methods

Retrospective analysis of first-time presentations in tumor conferences at a university musculoskeletal tumor center in the time periods from September 2019 to February 2020 (in-person) and May 2020 to October 2020 (virtual).

Results

A total of 209 patients were first-time discussed in one of 52 analyzed musculoskeletal multidisciplinary tumor conferences (105 patients in 25 in-person, and 104 patients 27 virtual meetings). The total number of participants was slightly lower with virtual meetings (p < .001) and more disciplines were represented in virtual tumor conferences (p < .001). With median six consultants present in either, the level of available expertise did not differ between the conference formats (p  =  .606). Compared to in-person tumor meetings, the patients were discussed earlier in the virtual conferences (p  =  .028). The interval between first presentation to biopsy was significantly shorter after virtual tumor conferences (median 4 vs. 7 days, p < .001). There was no significant difference in the interval between initial presentation and resection (p  =  .544) among the two conference formats.

Conclusions

The implementation of virtual tumor conferences appears to have had a positive effect on timely diagnosis and multidisciplinarity during tumor conferences. This may result in better decision-making and treatment of patients with musculoskeletal tumors and could be routinely implemented into cancer care.

Survival Associated With Consolidated Multidisciplinary Care in Head and Neck Cancer: A Retrospective Cohort Study

OBJECTIVE

To compare survival among patients with head and neck cancer before and after implementing a weekly multidisciplinary clinic and case conference.

METHODS

A retrospective cohort study with chart review was conducted of 3081 patients (1431 preimplementation, 1650 postimplementation) diagnosed with stage I-IVB tumors in the oral cavity, oropharynx, hypopharynx, nasopharynx, or larynx. Pre- and postimplementation differences in overall and disease-specific survival 1, 2, and 3 years after diagnosis were assessed with unadjusted Kaplan-Meier curves and multivariable Cox proportional hazard regression models adjusted for demographic characteristics, comorbidity burden, smoking status, tumor site and stage, p16 status for oropharyngeal squamous cell cancer, and initial treatment modality.

RESULTS

Patients less commonly presented with oropharyngeal squamous cell cancer and advanced tumors (III-IVB) and received primary treatment with surgery alone or with adjuvant therapy preimplementation than postimplementation. Overall survival at 3 years was 77.1% and 79.9% (P = .07) and disease-specific survival was 84.9% and 87.5% (P = .05) among pre- and postimplementation patients, respectively. At 3 years, preimplementation patients had slightly poorer overall (hazard ratio, 1.20; 95% CI, 1.02-1.40) and disease-specific (hazard ratio, 1.26; 95% CI, 1.03-1.54) adjusted survival than postimplementation patients. In unadjusted and adjusted analyses, survival improvements were more pronounced among patients with advanced disease.

DISCUSSION

A multidisciplinary clinic and case conference were associated with improved outcomes among patients with head and neck cancer, especially those with advanced tumors.

IMPLICATIONS FOR PRACTICE

All patients with head and neck cancer should receive multidisciplinary team management, especially those with advanced tumors.

Regionalization of Head and Neck Oncology Tumor Boards: Perspectives of Collaborating Physicians

Objectives

To survey academic and community physician preferences regarding the virtual multidisciplinary tumor board (MTB) for further improvement and expansion.

Study Design

This anonymous 14-question survey was sent to individuals that participated in the head and neck virtual MTBs. The survey was sent via email beginning August 3, 2021, through October 5, 2021.

Setting

The University of Maryland Medical Center and regional practices in the state of Maryland.

Methods

Survey responses were recorded and presented as percentages. Subset analysis was performed to obtain frequency distributions by facility and provider type.

Results

There were 50 survey responses obtained with a response rate of 56%. Survey participants included 11 surgeons (22%), 19 radiation oncologists (38%), and 8 medical oncologists (16%), amongst others. More than 96% of participants found the virtual MTB to be useful when discussing complex cases and impactful to future patient care. A majority of respondents perceived a reduction in time to adjuvant care (64%). Community and academic physician responses strongly agreed that the virtual MTB improved communication (82% vs 73%), provided patient-specific information for cancer care (82% vs 73%), and improved access to other specialties (66% vs 64%). Academic physicians, more so than community physicians, strongly agreed that the virtual MTB improves access to clinical trial enrollment (64% vs 29%) and can be useful in obtaining CME (64% vs 55%).

Conclusion

Academic and community physicians view the virtual MTB favorably. This platform can be adapted regionally and further expanded to improve communication between physicians and improve multidisciplinary care for patients.

Oral Candida spp. Colonisation Is a Risk Factor for Severe Oral Mucositis in Patients Undergoing Radiotherapy for Head & Neck Cancer: Results from a Multidisciplinary Mono-Institutional Prospective Observational Study

Simple Summary

This study aims to find a correlation between Candida spp. oral colonisation prior to radiotherapy and (i) the development of severe oral mucositis (OM) (grade 3/4) and (ii) early development of severe OM (EOM). Candida spp. in the oral cavity appears to be a predictive factor of EOM. Preventive treatment could aid in reducing incidence of EOM. Further clinical trials are required to confirm our findings.

Abstract

Background: This study aims to find a correlation between Candida spp. oral colonisation prior to radiotherapy (RT) and (i) the development of severe oral mucositis (OM) (grade 3/4) and (ii) early development of severe OM (EOM). Methods: The protocol was registered on ClinicalTrials.gov (ID: NCT04009161) and approved by the ethical committee of the ‘Fondazione Policlinico Universitario Gemelli IRCCS’ (22858/18). An oral swab was obtained before RT to assess the presence of Candida spp. Severe OM occurring before a dose of 40 Gy was defined as EOM. Results: No patient developed G4 OM, and only 36/152 patients (23.7%) developed G3 OM. Tumour site and lymphocytopenia were risk factors for severe OM (OR for tumour site: 1.29, 95% CI: 1–1.67, p = 0.05; OR for lymphocytopenia: 8.2, 95% CI: 1.2–55.8, p = 0.03). We found a correlation between Candida spp. and EOM (OR: 5.13; 95% CI: 1.23–21.4 p = 0.04). Patients with oral colonisation of Candida spp. developed severe OM at a mean dose of 38.3 Gy (range: 28–58; SD: 7.6), while negative patients did so at a mean dose of 45.6 Gy (range: 30–66; SD: 11.1). Conclusions: Candida spp. in the oral cavity appears to be a predictive factor of EOM.

Reliability of a Multidisciplinary Multiparametric Approach in the Surgical Planning of Laryngeal Squamous Cell Carcinomas: A Retrospective Observational Study

(1) Background: Endoscopy and morphological imaging are the mainstay of the diagnostic work up of laryngeal squamous cell carcinomas (LSCCs), which can be integrated in a multidisciplinary discussion to obtain a shared pretreatment staging. (2) Methods: A retrospective evaluation of patients, managed at a tertiary university hospital in Italy and submitted to major laryngeal surgery, has been performed. Four different stagings have been defined and compared: epTN (based on endoscopy and physical ENT examination); radTN (based on CT scan); cTN (based on multidisciplinary integration of the two above); pTN based on pathology on surgical samples. Oncological outcomes have been assessed. (3) Results: Three-year relapse free and disease specific survival were 88% and 92.5%, respectively, without significant differences between partial surgeries (n = 13) and total laryngectomies (n = 32). As for the pretreatment staging, and in particular the T classification, the cTN has been revealed as more reliable than epTN and radTN alone in predicting the final pT (Cohen kappa coefficient: 0.7 for cT, 0.44 for radT, 0.32 for epT). In the partial surgery group, we did not record any positive margin nor local recurrence, with a 100% overall and disease-specific survival. (4) Conclusions: The multidisciplinary approach is fundamental in the definition of the primary lesion in LSCC, in particular in order to safely perform surgical preservation of laryngeal function, which is associated with a higher laryngectomy-free survival than irradiation but to a lower salvageability in case of recurrence.

The Emergence of Virtual Tumor Boards in Neuro-Oncology: Opportunities and Challenges

Background

Virtual tumor board (VTB) platforms are an important aspect of cancer management. They enable easier access to a multidisciplinary team of experts. To deliver high-quality cancer care, it is necessary to coordinate numerous therapies and providers, share technical knowledge, and maintain open lines of communication among all professionals involved. The VTB is an essential tool in the diagnosis and treatment of brain cancer. For patients with glioma and brain metastases, multidisciplinary tumor board guidelines should guide diagnosis and therapy throughout the course of the illness. VTBs are an emerging resource across various cancer care networks in the United States.

Methodology

We performed a systematic search of all VTBs incorporating a platform designed for this specific role. We reviewed the records of the Genomet VTB, the Medical University of South Carolina (MUSC) VTB, and Xcures VTB. Summary data examined included the year of launch, demographics, characteristics of cases, average response time, advantages, and how they handle protected health information.

Results

Overall, 30% of VTBs examined were launched in 2017. All had a Health Insurance Portability and Accountability Act-compliant online environment. On a review of Xcures records, the median age of the female patients was 57 years and the median age of the male patients was 55 years. The data showed that 44% (4.4 out of every 10 patients) with a confirmed treatment chose the VTB integrated option. Overall, 76% of patients in the Xcures registry had primary central nervous system tumors, with at least 556 patients in the tumor registry which included 46% glioblastoma cases (96% primary, 4% secondary). In the MUSC VTB project, 112 thoracic tumor cases and nine neuro-oncology cases were reviewed. The tumor board met weekly, and the average response time was within 24 hours of case review and presentation. The Genomet VTB de-identifies all patient information; this is a virtual platform primarily focused on neuro-oncology cases. Cases involved a median of five specialists most commonly neuro-oncologists, neurosurgeons, radiation oncologists, molecular pathologists, and neuroradiologists. The case review revealed an age range of six months to 84 years (mean age = 44.5 years), with 69.6% males and 30.4% females, 43.5% glioblastomas, 8.7% adenocarcinomas, and 8.7% infratentorial tumors. The average response time observed in all cases was ≤24 hours.

Conclusions

VTBs allow for quicker expert analysis of cases. This has resulted in an accelerated number of cases reviewed with a shortened communication time. More studies are needed to gain additional insights into user engagement metrics.

Impact of AJCC 8th edition staging system and definitive treatment choice on the prognosis of complete responders with p16+ and p16− oropharyngeal squamous cell carcinomas

OBJECTIVES

To identify predictors of overall survival (OS) in oropharyngeal squamous cell carcinoma (OPSCC) patients who achieved complete response (CR).

METHODS

We performed a retrospective study of OPSCC patients who achieved CR from a single academic medical center. Associations between OS, AJCC 8th edition staging system, definitive treatment choice, smoking history, and p16 status were assessed.

RESULTS

p16+ status was associated with favorable prognosis for CR (p < 0.001) but not non-CR (p = 0.67) patients. For early stage, p16+ OPSCC patients who achieved CR, surgery + adjuvant radiation (RT) treatment was more durable compared to concurrent chemoradiation (CRT), particularly in smokers.

CONCLUSIONS

Curative intent treatment choice and smoking history has an impact on the long-term OS of the CR p16+ OPSCC cohort. Prospective studies to define the optimal multi-modality treatment option to manage p16+ OPSCC patients is needed.

Clinical variation in the organization of clinical pathways in esophagogastric cancer, a mixed method multiple case study

Background

Among esophagogastric cancer patients, the probability of having undergone treatment with curative intent has been shown to vary, depending on the hospital of diagnosis. However, little is known about the factors that contribute to this variation. In this study, we sought to understand the organization of clinical pathways and their association with variation in practice.

Methods

A mixed-method study using quantitative and qualitative data was conducted. Quantitative data were obtained from the Netherlands Cancer Registry (e.g., outpatient clinic consultations and diagnostic procedures). For qualitative data, thematic content analysis was performed using semi-structured interviews (n = 30), observations of outpatient clinic consultations (n = 26), and multidisciplinary team meetings (MDTM, n = 16) in eight hospitals, to assess clinicians’ perspectives regarding the clinical pathways.

Results

Quantitative analyses showed that patients more often underwent surgical consultation prior to the MDTM in hospitals associated with a high probability of receiving treatment with curative intent, but more often consulted with a geriatrician in hospitals associated with a low probability of such treatment. The organization of clinical pathways was analyzed quantitatively at three levels: regional, local, and patient levels. At a regional level, hospitals differed in terms of the number of patients discussed during the MDTM. At the local level, the revision of radiological images and restaging after neoadjuvant treatment varied. At the patient level, some hospitals routinely conduct fitness tests, whereas others estimated the patient’s physical fitness during an outpatient clinic consultation. Few clinicians performed a standard geriatric consultation in older patients to assess their mental fitness and frailty.

Conclusion

Surgical consultation prior to MDTM was more often conducted in hospitals associated with a high probability of receiving treatment with curative intent, whereas a geriatrician was consulted more often in hospitals associated with a low probability of receiving such treatment.

Neuro-Oncology Multidisciplinary Tumor Board: The Point of View of the Neuroradiologist

Background: The multi-disciplinary tumor board (MTB) is essential to quality cancer care and currently recommended to offer the best personalized clinical approach, but little has been published regarding MTBs in neuro-oncology (nMTBs). The aim of the present paper is to describe our nMTB, to evaluate its impact on clinical management decisions, and to assess the role of neuroradiologists. Methods: The retrospective evaluation of the cases discussed at our nMTB from March 2017 to March 2020. From the electronic records, we extracted epidemiological, clinical and other specific data of nMTB. From the radiological records, we calculated data relating to the number, time for revision, and other specifications of MRI re-evaluation. Statistical analysis was performed. Results: a total of 447 discussions were analyzed, representing 342 patients. The requests for case evaluations came from radiation oncologists (58.8%) and neurosurgeons (40.5%), and were mainly addressed to the neuroradiologist (73.8%). The most frequent questions were about the treatment’s changes (64.4%). The change in patient treatment was reported in 40.5% of cases, 76.8% of these were based on the neuroradiologic assessment. A total of 1514 MRI examinations were re-evaluated, employing approximately 67 h overall. The median of the MRI exams reviewed per patient was 3 (min–max 1–12). Conclusions: Our study supported that the multidisciplinary approach to patient care can be particularly effective in managing brain tumors. A review by an expert neuroradiologist impacts patient management in the context of nMTBs, but has costs in terms of the time and effort spent preparing for it.

Upfront surgical organ-preservation strategy in advanced-stage laryngeal cancer

PURPOSE

Advanced-stage laryngeal cancer is a challenging disease that needs multimodal treatment. Medical and surgical organ-preservation strategies have been developing in the last decades to spare these functions while granting cancer cure. The current work presents the experience of a tertiary-care center in conservative surgery for advanced-stage laryngeal cancer.

MATERIALS AND METHODS

We collected clinical data of patients submitted to open partial horizontal laryngectomies (OPHLs) and any possible adjuvant treatment from 2005 to 2018. Outcomes were also compared to the most recent studies reporting on both medical and surgical organ-preservation strategies.

RESULTS

One hundred ten patients were included in the analysis. Adjuvant therapy was employed in 51% of cases. The local control rate was 96.4%, while overall survival (OS) was 67%, and laryngo-esophageal dysfunction free survival (LEDFS) was 66%. Stage IV and vascular invasion were associated with a statistically-significant worse survival.

CONCLUSIONS

OPHLs are valid as upfront treatment in fit patients affected by advanced-stage laryngeal cancer. Disease control and function preservation are granted in a significant percentage of cases, even when followed by adjuvant therapy.

Standardized Diagnostic Workup and Patient-Centered Decision Making for Surgery and Neck Dissection Followed by Risk-Factor Adapted Adjuvant Therapy Improve Loco-Regional Control in Local Advanced Oral Squamous Cell Carcinoma

Background

Standardized staging procedures and presentation of oral squamous cell carcinoma (OSCC) patients in multidisciplinary tumor boards (MDTB) before treatment and utilization of elective neck dissection (ND) are expected to improve the outcome, especially in local advanced LAOSCC (UICC stages III–IVB). As standardized diagnostics but also increased heterogeneity in treatment applied so far have not been demonstrated to improve outcome in LAOSCC, a retrospective study was initiated.

Methods

As MDTB was introduced into clinical routine in 2007, 316 LAOSCC patients treated during 1991-2017 in our hospital were stratified into cohort 1 treated before (n=104) and cohort 2 since 2007 (n=212). Clinical characteristics, diagnostic procedures and treatment modality of patients were compared using Chi-square tests and outcome analyzed applying Kaplan-Meier plots and log-rank tests as well as Cox proportional hazard regression. Propensity scores (PS) were used to elucidate predictors for impaired distant metastasis-free survival (DMFS) in PS-matched patients.

Results

Most patient characteristics and treatment modalities applied showed insignificant alteration. Surgical treatment included significantly more often resection of the primary tumor plus neck dissection, tracheostomy and percutaneous endoscopic gastrostomy tube use. Cisplatin-based chemo-radiotherapy was the most frequent. Only insignificant improved disease- (DFS), progression- (PFS) and event-free (EFS) as well as tumor-specific (TSS) and overall survival (OS) were found after 2006 as local (LC) and loco-regional control (LRC) were significantly improved but DMFS significantly impaired. Cox regression applied to PS-matched patients elucidated N3, belonging to cohort 2 and cisplatin-based chemo-radiotherapy as independent predictors for shortened DMFS. The along chemo-radiotherapy increased dexamethasone use in cohort 2 correlates with increased DM.

Conclusions

Despite standardized diagnostic procedures, decision-making considering clear indications and improved therapy algorithms leading to improved LC and LRC, shortened DMFS hypothetically linked to increased dexamethasone use had a detrimental effect on TSS and OS.

Fanconi anemia and hematopoietic stem cell transplant as risk factors for oral squamous cell carcinoma: A case report with a 12-year follow-up

Fanconi anemia is a rare disorder resulting from defects in genes responsible for DNA damage responses. It is characterized by congenital anomalies, aplastic anemia, and a predisposition to cancer. Currently, hematopoietic stem cell transplant (HSCT) is the only curative treatment available for bone marrow failure; however, HSCT increases oral squamous cell carcinoma (OSCC) risk. Here we report the case of a patient diagnosed with Fanconi anemia in childhood who was treated with HSCT and later diagnosed with multiple OSCCs during a 12-year follow-up. Despite multiple surgical interventions and radiotherapy regimens, the patient`s health deteriorated. Management of individuals with Fanconi anemia is challenging and must be provided by a multidisciplinary healthcare team to ensure better staging, treatment planning, and coordination.

Quality improvement intervention to reduce time to postoperative radiation in head and neck free flap patients

BACKGROUND

Best-practice guidelines for head and neck cancer patients advise postoperative radiation therapy (PORT) initiation within 6 weeks of surgery. We report our institutional experience improving timeliness of adjuvant radiation in free-flap patients.

METHODS

Thirty-nine patients met inclusion criteria in the 2017-2019 study period. We divided into "Early" (n = 19) and "Late" (n = 20) time-period groups to compare performance over time. The primary endpoint was time to PORT initiation, with success defined as <6 weeks.

RESULTS

The number of patients achieving timely PORT improved from 10.5% in the Early group to 50.0% in the Late group (p = 0.014). Patients undergoing concurrent adjuvant chemoradiation were more likely to meet the PORT target in the Late group (p = 0.012).

CONCLUSIONS

We ascribe this quality improvement in free-flap patients to increased communication among multidisciplinary care teams, proactive consultation referrals, and a targeted patient-navigator intervention. Though work is needed to further improve performance, insight gained from our experience may benefit other teams.

Influence of endocrine multidisciplinary tumor board on patient management and treatment decision making

BACKGROUND

Multidisciplinary Tumor Boards (MDT) are used to obtain input regarding cancer management. This study assessed the impact of our institutional Endocrine MDT.

METHODS

MDT notes on patients with thyroid cancer treated during 2012-2018 were abstracted retrospectively from the electronic medical record. Management change (MC) was prospectively collected by the MDT coordinator. Biannual evaluations reviewed the impact of the MDT as observed by attendees.

RESULTS

MC was recommended in 47 (15%) of 286 presentations, with additional imaging being the most frequent (43%). Presentation of recurrences were more likely to result in MC (24% vs. 13% initial, p = 0.03). Overall, 98% of attendees found the conference exceeded educational expectations. About 24% reported intending to use a more evidence/guideline-based approach after attending and this trend increased over time (p = 0.002).

CONCLUSION

MDT presentations led to a higher rate of MC particularly in recurrent TC patients and increased evidenced-based practice for attendees.

Preoperative Immunotherapy in the Multidisciplinary Management of Oral Cavity Cancer

Despite advances in multimodal treatment for oral cavity squamous cell carcinoma, recurrence rates remain high, providing an opportunity for new therapeutic modalities that may improve oncologic outcomes. Much recent attention has been paid to the molecular interactions between the tumor cells with the adjacent peritumoral microenvironment, in which immunosuppressive molecular changes create a landscape that promotes tumor progression. The rationale for the introduction of immunotherapy is to reverse the balance of these immune interactions in a way that utilizes the host immune system to attack tumor cells. In the preoperative setting, immunotherapy has the advantage of priming the unresected tumor and the associated native immune infiltration, supercharging the adaptive anti-tumor immune response. It also provides the basis for scientific discovery where the molecular profile of responders can be interrogated to elucidate prognostic markers to aid in future patient selection. Preoperative immunotherapy is not without limitations. The risk of surgical delay due to immune adverse events must be carefully discussed by members of a multidisciplinary treatment team and patient selection will be critical. One day, the discovery of predictive biomarkers may allow for algorithms where pre-surgical immunotherapy decreases the size of surgical defect and impacts the intensity of adjuvant therapy leading to improved patient survival and decreased morbidity. With further study, immunotherapy could become a key component of future treatment algorithm.

Barriers to Comprehensive Multidisciplinary Head and Neck Care in a Community Oncology Practice

Complex, coordinated, and collaborative care of patients with head and neck cancer can be challenging yet amazingly rewarding and successful. The high symptom burden across multiple functional domains in patients with head and neck cancer, even in early stages of disease, mandates a multidisciplinary team approach that harnesses the combined contributions of physicians and ancillary providers to drive greater patient-centered care, addressing factors that heavily influence morbidity, mortality, and quality of life. Well-organized community-based multidisciplinary teams fulfill this unmet need and benefit patients with conveniently located comprehensive services that are typically found in large academic centers. Equivalent, if not superior, outcomes can be achieved in a unified community-based multidisciplinary team with shared patient-centered and outcomes-based goals. However, implementing true multidisciplinary team care in today's complex health care environment is fraught with challenges and pitfalls. So how have some community-based practices managed to create safe and efficient programs with successful outcomes? The purpose of this review is to discuss barriers to reaching this success and emphasize practical solutions to such challenges.

Appraisal of clinical practice guidelines for the evaluation and management of neck masses in children

AIM

The purpose of this systematic review was to use the Appraisal of Guidelines for Research and Evaluation tool to assess the methodological quality of clinical practice guidelines (CPGs) for the workup and management of paediatric neck masses.

METHODS

MEDLINE, Embase, Cochrane and grey literature were searched to identify CPG incorporating paediatric neck masses. Four authors with previous training of the Appraisal of Guidelines for Research and Evaluation tool evaluated the included studies.

RESULTS

Nine studies met inclusion criteria. The highest scoring domains were 'Scope and Purpose' (74.0 ± 4.5) and 'Clarity of Presentation' (72.9 ± 6.3). The lowest scoring domains were 'Rigour and Development' (18.8 ± 7.5) and 'Applicability' (23.7 ± 6.1). One study was 'High' quality, three received scores of 'Average' and five were found to be 'Low' quality.

CONCLUSION

The majority of paediatric neck mass CPGs were low to average quality. The domains in need of greatest improvement were 'Rigour and Development' and 'Applicability', suggesting significant concerns in current CPGs focused on paediatric neck masses.

Multi-Disciplinary Skull Base Conference and its Effects on Patient Management

OBJECTIVE

Examine the effects of a multi-disciplinary skull base conference (MDSBC) on the management of patients seen for skull base pathology in a neurotology clinic.

METHODS

Retrospective case review of patients who were seen in a neurotology clinic at a tertiary academic medical center for pathology of the lateral skull base and were discussed at an MDSBC between July 2019 and February 2020. Patient characteristics, nature of the skull base pathology, and pre- and post-MDSBC plan of care was categorized.

RESULTS

A total of 82 patients with pathology of the lateral skull base were discussed at a MDSBC during an 8-month study period. About 54 (65.9%) had a mass in the internal auditory canal and/or cerebellopontine angle while 28 (34.1%) had other pathology of the lateral skull base. Forty-nine (59.8%) were new patients and 33 (40.2%) were established. The management plan changed in 11 (13.4%, 7.4-22.6 95% CI) patients as a result of the skull base conference discussion. The planned management changed from some form of treatment to observation in 4 patients, and changed from observation to some form of treatment in 4 patients. For 3 patients who underwent surgery, the planned approach was altered.

CONCLUSIONS

For a significant proportion of patients with pathology of the lateral skull base, the management plan changed as a result of discussion at an MDSBC. Although participants of a MDSBC would agree of its importance, it is unclear how an MDSBC affects patient outcomes.

Physician practice variation in head and neck cancer therapy: Results of a national survey

OBJECTIVES

Choice between surgical or medical treatments in head and neck cancer depends of many patient-related and disease-related factors. We investigated how patients' socioeconomic status and practitioners' specialty could affect medical decision-making.

MATERIALS AND METHODS

We conducted a cross-sectional online, nationwide survey, send to surgeons, oncologists and radiotherapists specialized in head and neck oncology. We collected data on medical decision-making for seven clinical scientific scenarios involving head and neck carcinoma and physicians' demographic data. Patients' gender and socioeconomic position were distributed across scientific scenarios using a Latin square design. The scientific scenarios were grouped into several categories according to the prognostic and functional impact of the therapeutic choice.

RESULTS

We obtained 206 assessable answers. Surgeons seemed to propose surgery in 49% of cases, whereas oncologists and radiotherapists opted for it in 34% of cases only. This was particularly relevant when the oncological result of surgery and the medical approach were equivalent, and when the surgery appeared to be superior in terms of curative potential but was burdened by a large functional impact. Patient's socioeconomic position also influence therapeutic decision. Among surgeons, the "single male manager" had significantly more chance of being offered surgery than the "married male blue-collar worker". Among oncologists and radiotherapists, the "single male blue-collar worker" had the lowest probability of being proposed surgery. Regarding gender, surgeons tended to offer surgical management more to women regardless of their clinical profile.

CONCLUSIONS

Patients' sex, marital status, socioeconomic status, practitioners' specialty affect therapeutic management decisions in head and neck oncology.

Impact of Multidisciplinary Team Management on the Survival Rate of Head and Neck Cancer Patients: A Cohort Study Meta-analysis

Background: Head and neck cancer (HNC) is one of the more common malignant tumors that threaten human health worldwide. Multidisciplinary team management (MDTM) in HNC treatment has been introduced in the past several decades to improve patient survival rates. This study reviewed the impact of MDTM on survival rates in patients with HNC compared to conventional treatment methods.

Methods: Only cohort studies were identified for this meta-analysis that included an exposure group that utilized MDTM and a control group. Heterogeneity and sensitivity also were assessed. Survival rate data for HNC patients were analyzed using RevMan 5.2 software.

Results: Five cohort studies (n = 39,070) that examined survival rates among HNC patients were included. Hazard ratios (HR) were calculated using the random effect model. The results revealed that exposure groups treated using MDTM exhibited a higher survival rate [HR = 0.84, 95% CI (0.76–0.92), P = 0.0004] with moderate heterogeneity (I² = 68%, p = 0.01). For two studies that examined the effect of MDTM on the survival rate for patients specifically with stage IV HNC, MDTM did not produce any statistically significant improvement in survival rates [HR = 0.81, 95% CI (0.59–1.10), p = 0.18].

Conclusions: The application of MDTM based on conventional surgery, radiotherapy, and chemotherapy improved the overall survival rate of patients with HNC. Future research should examine the efficacy of MDTM in patients with cancer at different stages.

Do Multidisciplinary Tumor Board Discussions Correlate With Increase in 5-Year Survival? A Meta-Analysis Study

Introduction

Due to the complex nature of cancer cases, it is imperative that the involved healthcare providers coordinate the patients care plan in union to reach the best possible outcome in the smoothest and fastest manner. This is what multidisciplinary tumor board (MTB) meetings strive to achieve. Conducting regular MTB meetings requires significant investment of time and finances. It is thus vital to assess the empirical benefits of such practice.

Methods

A meta-analysis was conducted to evaluate the literature regarding the impact of MTB meetings on patient 5-year survival. Relevant studies were identified by searching Ovid MEDLINE and Embase databases from January 1995 to July 2019. Studies were included if they assessed 5-year survival in cases discussed in MTB meetings and used a comparison group and/or a pretest and posttest design.

Results

Five articles met the study's inclusion criteria. Quality of studies was affected by selection bias and the use of historic cohorts. The results showed significantly improved 5-year survival in the MTB group compared with the non-MTB groups (odds ratio for 5-year death rate of 0.59, CI 0.45-0.78, p < 0.001).

Conclusion

This meta-analysis showed that cancer MTB meetings have a significant impact on patients' 5-year survival. This could be because of several reasons, such as less time to treatment initiation, better adherence to guidelines, higher numbers of investigational imaging, lesser surgical complications, and recurrence rates. Future prospective studies are needed to further delineate reasons for improvement of outcome to enhance the benefits of this approach.

Patterns of Multidisciplinary Care of Head and Neck Squamous Cell Carcinoma in Medicare Patients

Importance

Multidisciplinary care (MDC) yields proven benefits for patients with cancer, although it may be underused in the complex management of head and neck squamous cell carcinoma (HNSCC).

Objective

To characterize the patterns of MDC in the treatment of HNSCC among elderly patients in the US.

Design, Setting, and Participants

This nationwide, population-based, retrospective cohort study used Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data from January 1, 1991, to December 31, 2011, to identify patients 66 years or older diagnosed with head and neck cancer and determine the dates of diagnosis, oncology consultations, treatment initiation, and speech therapy evaluation in addition to MDC completion. Multidisciplinary care was defined in a stage-dependent manner: localized disease necessitated consultations with radiation and surgical oncologists, and advanced-stage disease also included a medical oncology consultation, all before definitive treatment. Data were analyzed between December 2016 and September 2020.

Main Outcomes and Measures

Rates of MDC across all subsites of head and neck cancer as measured by the presence of an evaluation for each oncologist on the MDC team and its effect on treatment initiation.

Results

This cohort study assessed 28 293 patients with HNSCC (mean [SD] age, 75.1 [6.6] years; 67% male; 87% White) from the SEER-Medicare linked database. The HNSCC subsites included larynx (40%), oral cavity (30%), oropharynx (21%), hypopharynx (7%), and nasopharynx (2%). Overall, the practice of MDC significantly increased over time, from 24% in 1991 to 52% in 2011 (P < .001). For patients with localized (stage 0-II) tumors, 60% received care in the multidisciplinary setting, whereas 28% of those with advanced-stage disease did. A total of 18 181 patients (64%) were treated with initial definitive nonsurgical therapy across all stages. Regardless of stage and subsite, few patients (2%) underwent evaluation by a speech-language pathologist before definitive therapy. Multidisciplinary care prolonged the time to initiation of definitive treatment by 11 days for localized disease and 10 days for advanced disease.

Conclusions and Relevance

This cohort study found that most elderly patients with localized HNSCC received MDC, whereas few patients with advanced-stage disease received such care, although a significant proportion received adjuvant therapy. Multidisciplinary care may prolong time to initiation of definitive treatment with an uncertain impact. Consultation with a speech-language pathologist before definitive therapy was rare.

Benefits and Limitations of a Multidisciplinary Approach in Cancer Patient Management

Over the years, a growing body of literature has confirmed as beneficial the implementation of a multidisciplinary approach in the so-often-intricate scenario of cancer patients' management. Together with the consolidation of tumor-board experience in clinical practice, certain aspects have emerged as controversial and a source of current debate. In this systematic literature review, we focused our attention on the impact of multidisciplinary tumor boards, assessing benefits and limitations as a result of the dissemination of such approaches. On the bright side, adherence to clinical guidelines, treatment outcomes, and overall improvement in decision-making processes have been recognized as advantages. On the other side, our analysis highlights a few limitations that should be taken into account to optimize cancer patients' management. Of note, some issues, such as costs, legal responsibility, geographic barriers, and treatment delays, have yet to be resolved. In order partly to address this matter, software platforms and novel methods of computational analysis may provide the needed support. Therefore, the aim of our analysis was to describe the multidisciplinary approach in cancer care in terms of adherence to clinical guidelines, treatment outcomes, and overall improvement in decision-making processes through a systematic review of the literature.
