Impact of dose distribution by a 3D planning system for brachytherapy with 198Au grains for head and neck cancer. Head Neck 2024. [PMID: 39011775 DOI: 10.1002/hed.27874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 06/30/2024] [Accepted: 07/07/2024] [Indexed: 07/17/2024] Open
Abstract
BACKGROUND There has been no study in which the correlation between clinical results and dosimetry based on a 3D treatment planning system in patients with 198Au grains for head and neck cancer was evaluated. METHODS Thirty-two patients who were treated with 198Au grains for head and neck cancer were reviewed. Twenty-five patients were treated with brachytherapy alone and seven patients were treated with a combination of brachytherapy and neoadjuvant external beam radiation therapy. RESULTS With a median observation period of 60 months, the 5-year local control rate was 82.9%. V85Gy of CTV in patients with local recurrence tended to be lower than that in patients without local recurrence (p = 0.07). The maximum dose of the keratinized gingiva in patients in whom bone exposure occurred was significantly higher than that in patients in whom bone exposure did not occur (p = 0.001). CONCLUSIONS Dose distribution with 198Au grains can predict local control and late adverse events.

Abstract
Background The late presentation of oral squamous cell carcinoma (OSCC) patients in Sudan, with advanced stages and wide field of cancerization (WFC), has a negative impact on these patients. The present study aimed to investigate the different clinical presentations of mucosal changes in WFC associated with OSCC in Sudanese patients. Methods This a prospective longitudinal study of 93 OSCC cases. Tumor's associated field of cancerization was identified and related clinical mucosal changes were described. Results Out of the 93 patients, 57 (61.3%) were males and 36 (38.7%) were females. Eighty-two percent of the patients presented with stage IV tumors. Ninety-two patients had multiple sites involved in the oral cavity with overlap of sites involved. The Gingivobuccal mucosa (74.2%) was the most frequent site involved. Eighty-three (89.2%) of the lesions were surrounded by mucosal changes, of them 32 (38%) surrounded by a grizzle (mixed dark and white) discoloration and 21 (26%) were surrounded by a white-smoke discoloration followed by 17 (20%) and 13 (16%) surrounded by cotton-white and Café au lait discolorations, respectively. Forty-four (47.3%) lesions had overlapping presentations and surrounded by erythematous patches. Conclusion The present study showed that OSCC patients in Sudan present with advanced lesions, mostly associated with WFC, particularly the Toombak dippers. The different mucosal changes seen in the WFC associated with OSCC in these cases are in accordance with the known five mucosal presentations.

Abstract
Objectives To present a new method to assess the cervical lymph nodes status in head and neck cancer patients. Methods Twenty-five oral and maxillofacial cancer patients underwent preoperative CT imaging. The cervical lymph node features on CT scan were examined. Each parameter was given a score, and the total scores in each case was calculated and referred to as metastatic score (MS). Then, patients underwent neck dissection, and all dissected lymph nodes were sent for histopathology. Results All cases with MS ≥ 6 were histopathologically positive, and all cases with MS ≤ 3 were histopathologically negative. All cases of nodal sizes > 3 cm were histopathologically positive, 82% of cases of nodal sizes between 2.1 and 3 cm were histopathologically positive, 40% of cases of nodal sizes between 1 and 2 cm were histopathologically positive, and all cases of lymph nodes sizes < 1 cm were histopathologically negative. Seventy-seven percent of cases which had a group of lymph nodes ≥ 3 nodes/region were histopathologically positive, while 79% of cases with rounded nodes were histopathologically positive, and all cases with necrotic lymph nodes were positive for malignancy. Conclusion The proposed formula is a good assessment tool for cervical lymph nodes evaluation using helical CT scan in head and neck cancer patients.

Abstract
Introduction: Oral squamous cell carcinoma (OSCC) ranks among the top 10 leading causes of cancer worldwide, with 5-year survival rate of about 50%, high lymph node metastasis, and relapse rates. The OSCC diagnosis, prognosis, and treatment are mostly based on the clinical TNM classification. There is an urgent need for the discovery of biomarkers and therapeutic targets to assist in the clinical decision-making process.Areas covered: We summarize proteomic studies of the OSCC tumor, immune microenvironment, potential liquid biopsy sites, and post-translational modifications trying to retrieve information in the discovery and verification or (pre)validation phases. The search strategy was based on the combination of MeSH terms and expert refinement.Expert opinion: Untargeted combined with targeted proteomics are strategies that provide reliable and reproducible quantitation of proteins and are the methods of choice of many groups worldwide. Undoubtedly, proteomics has been contributing to the understanding of OSCC progression and uncovers potential candidates as biomarker or therapeutic targets. Nevertheless, none of these targets are available in the clinical practice yet. The scientific community needs to overcome the limitations by investing in robust experimental designs to strengthen the value of the findings, leveraging the translation of knowledge, and further supporting clinical decisions.

[PMID: 33546063 PMCID: PMC7837872 DOI: 10.1097/md.0000000000024327] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 12/20/2020] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVES In this study, a meta-analysis was conducted to evaluate the occult lymph node metastasis rate in patients with early-stage (T1-T2) oral tongue squamous cell carcinoma. Also, the correlation between occult lymph node metastasis rate and T2 ratio among T1-T2 or the reported year of each study was analyzed to adjust other confound variables. STUDY DESIGN Literature search. METHODS A systematic computerized search of the electronic databases was carried out for articles published between January 1, 1980, and December 31, 2018, which reported occult nodal metastasis rate in T1 and T2 (separately) tongue cancer patients. Statistical analysis was performed using Comprehensive Meta Analysis version 3.3.070. Publication bias was assessed by the Egger test and Begg funnel plot method. The correlation between occult nodal metastasis rate and T2 ratio or reported year, respectively, was assessed by meta-regression analysis. RESULTS From 19 studies, a total of 1567 cases were included in the meta-analysis. By random effects model, the mean occult cervical lymph node metastasis was 24.4% (95% confidence interval; 0.205-0.248). The meta-regression revealed that the T2 ratio and the reported year of the studies did not have a significant effect on the occult metastasis rate (correlation coefficient = 0.531 and 0.002, respectively, and P = .426 and 0.921, respectively). CONCLUSION The meta-analysis revealed that the early-stage oral tongue squamous cell carcinoma had a rate of 24.4% for occult nodal metastasis. The occult nodal metastasis rate was not significantly affected by neither T2 ratio among T1-T2 nor reported year of the studies.

Abstract
OBJECTIVES Depth of invasion (DOI) is the most important predictor for lymph node metastasis (LNM) in early stage (T1-T2) oral cancer. The aim of this study is to validate the cut-off value of 4 mm on which the decision to perform an Elective Neck Dissection (END) is made. MATERIALS AND METHODS We performed a retrospective study in patients with pathologically proven early stage oral cavity squamous cell carcinoma (OCSCC) without clinical or radiological signs of LNM, who were treated between 2013 and 2018. An END was performed when DOI was ≥ 4 mm and a watchful waiting protocol was applied in patients with DOI < 4 mm. RESULTS Three hundred patients were included. END was performed in 77% of patients with DOI ≥ 4 mm, of which 36% had occult LNM (pN+). Patients in the watchful waiting group (48%) developed a regional recurrence in 5.2% for DOI < 4 mm and 24.1% for DOI ≥ 4 mm. For DOI ≥ 4 mm, regional recurrence free survival was higher for patients who were treated with END compared to watchful waiting (p = 0.002). A Receiver-Operator-Curve -analysis showed that a DOI cut-off value of 4.0 mm was the optimal threshold for the prediction of occult LNM (95.1% sensitivity, 52.9% specificity). CONCLUSION A DOI of ≥ 4 mm is an accurate cut-off value for performing an END in early stage OCSCC. END results in higher survival rates and lower regional recurrence rates in patients with DOI ≥ 4 mm.

Abstract
Objective: Neck management in cT1-2N0 tongue squamous cell carcinoma (SCC) remains controversial. Our goal was to compare the survival difference between PET-CT–guided neck dissection and elective neck dissection (END) for the treatment of cT1-2 tongue SCC. Methods: Patients with surgically treated cT1-2N0 tongue SCC were retrospectively enrolled. These patients were divided into two groups. Group A: The decision of whether to perform neck dissection was mainly based on the results of preoperative PET-CT examinations. Group B: Patients received END treatment without preoperative PET-CT examinations. The study endpoints were regional control (RC) and disease-specific survival (DSS). The Kaplan–Meier method was used to calculate the survival rates. Results: Group A consisted of 66 patients, and 16 patients underwent neck dissection owing to positive PET-CT results. Group B consisted of 169 patients. The 5-year RC rates in group A and group B were 86 and 87%, respectively, and the difference was not significant (p = 0.731). The 5-year DSS rates in group A and group B were 93 and 90%, respectively, and the difference was not significant (p = 0.583). Conclusions: Neck dissection can be safely avoided when the PET-CT scan reveals no neck lymph node involvement.

Abstract
Background: In stage-I/stage-II oral tongue cancer, the cutoff value of depth of invasion (DOI) for prophylactic neck dissection is controversial.Objectives: To examine the relationship between the DOI and the rate of occult lymph node metastasis. In addition, to examine the relationship between the DOI evaluated by magnetic resonance imaging (MRI) and pathological DOI.Materials and methods: In this retrospective study, 95 patients with clinical T1-2/N0M0 oral tongue cancer were enrolled. The rate of occult lymph node metastasis per DOI between 2 and 11 mm was calculated from the total pathological lymph node metastasis and delayed neck metastasis cases. We measured DOI using MRI and compared DOI obtained from pathology.Results: The total rate of occult lymph node metastasis was 23.9%. In the rate of occult lymph node metastasis per DOI, there were two peaks at point of 5 to 6 mm and 9 to 10 mm. And there was a significant correlation between the DOI evaluated by MRI and the pathological DOI (Pearson's correlation coefficient was 0.87).Conclusions and significance: There was no consistent increase in the rate of occult lymph node metastasis per DOI. MRI was a useful modality to measure the DOI.
