RESUMO

To determine the intracellular behavior of p62, a marker of selective autophagy, in oral potentially malignant disorders (OPMDs). This retrospective study includes 70 patients who underwent biopsy or surgical resection and were definitively diagnosed with OPMDs. Immunohistochemical staining for p62, XPO1, p53, and ki67 was performed on all samples and positive cell occupancy was calculated. We statistically investigated the correlation between protein expression in OPMDs and the association between malignant transformation, clinicopathological characteristics, and occupancy. ki67 expression was negatively correlated with p62 expression in the nucleus (p < 0.01) and positively correlated with p62 expression in the cytoplasm (p < 0.01). For malignant transformation, the expression of p62 in the nucleus (p = 0.03) was significantly lower in malignant transformation cases, whereas the expression of p62 in the cytoplasm (p = 0.03) and the aggregation expression (p < 0.01) were significantly higher. Our results suggest that the function of p62 is altered by its subcellular localization. In addition, defects in selective autophagy occur in cases of malignant transformation, suggesting that p62 is a potential biomarker of the risk of malignant transformation of OPMDs.

RESUMO

Anterior maxillary distraction osteogenesis (AMDO) surgery for cleft lip and palate involves distraction of a segment of the anterior maxilla and advancement using 2 intraoral buccal bone-borne distraction devices. The anterior part of the maxilla is advanced anteriorly with less relapse which increases maxillary length and does not affect speech. We aimed to evaluate the effects of AMDO, including lateral cephalometric changes. Seventeen patients who had undergone this procedure were included in this retrospective study. The distractors were activated by 0.5 mm twice a day after a 3-day latency period. Lateral cephalometric radiographs were evaluated preoperatively, after distraction and removal of distractors, which were compared using the paired Student's t test. Anterior maxillary advancement was obtained in all patients with a median of 8.0 mm. Complications included nasal bleeding and loosening of distractors; however, there was no tooth damage or abnormal movement. The mean sella-nasion-A point (SNA) angle increased significantly, from 74.91° to 79.66°, the A point-nasion-B point angle from -0.38° to 4.34°, and the perpendicular line from nasion to Frankfort Horizontal (NV)-A point from -5.11 to 0.08 mm. The mean anterior nasal spine-posterior nasal spine length increased significantly from 50.74 to 55.10 mm, and the NV-Nose Tip from 23.59 to 26.27 mm. The mean relapse rate of NV-A was 11.1%. AMDO with bone-borne distractor resulted in less relapse and effectively corrected the maxillary retrusion.

RESUMO

OBJECTIVES: Immunotherapy with nivolumab for patients with recurrent/metastatic oral squamous cell carcinoma has not been evaluated. Here, we aimed to examine the efficacy, safety, and prognostic factors of nivolumab in these patients. MATERIALS AND METHODS: This multicenter retrospective observational study involved patients who received nivolumab between April 2017 and June 2019. The patient characteristics were evaluated for association with progression-free and overall survival. Progression-free and overall survival rates were calculated; parameters that were significant in the univariate analysis were used as explanatory variables. Independent factors for progression-free and overall survival were identified using multivariate analysis. RESULTS: Totally, 143 patients were included. The overall response and disease control rates were 27.3% and 46.2%, respectively. The median, 1- and 2-year progression-free survival rates were 2.7 months, 25.4%, and 19.2%, respectively; those for overall survival were 11.2 months, 47.3%, and 33.6%, respectively. The independent factors affecting progression-free survival were performance status and immune-related adverse event occurrence, whereas those affecting overall survival were performance status, target disease, and number of previous lines of systemic cancer therapy. Eight patients reported grade ≥3 immune-related adverse events. CONCLUSION: Nivolumab was effective for recurrent/metastatic oral squamous cell carcinoma treatment and was well tolerated by patients.

RESUMO

PURPOSE: Detecting deep vein thrombosis (DVT) is necessary to reduce the morbidity of venous thromboembolism, and platelet-lymphocyte ratio (PLR) is a novel marker for predicting DVT. This study aimed to investigate the association between preoperative PLR and risk of developing DVT in patients receiving surgical treatment of oral cancer. PATIENTS AND METHODS: We designed a retrospective cohort study, and the source of study sample was patients with oral cancer and who underwent surgery between 2015 and 2019. Patients were excluded if they did not undergo surgical treatment and had preoperative DVT and history of hypercoagulable disorders. The primary predictor variable was PLR. We calculated the receiver operating characteristic curve and area under the curve to determine the best-defined risk groups. The best cutoff value for PLR was 187.4 (area under the curve, 0.772; sensitivity, 75.0%; specificity, 74.2%; P = .002). The primary outcome variable was DVT, and the other variables were patient characteristics, blood examination data, and therapeutic data. A logistic regression analysis was used to adjust the effects of potential confounders. RESULTS: A total of 101 patients were included in this study, and DVT was observed in 12 (11.9%) patients. Free flap reconstructive surgery was performed in 8 of the 12 (66.7%) patients in the DVT group. Statistical analyses showed that DVT was significantly associated with PLR (≤187.4 vs >187.4; P = .001). Logistic multivariate analysis of the preoperative parameters identified the following 2 independent predictive factors for DVT: PLR (≤187.4 vs >187.4) (odds ratio, 13.735; 95% confidence interval, 2.950 to 63.944; P = .001) and free flap reconstructive surgery (odds ratio, 6.584; 95% confidence interval, 1.504 to 28.822; P = .012). CONCLUSIONS: High PLR (>187.4) and free flap reconstructive surgery, considered as preoperative predictive factors, were associated with DVT.

RESUMO

PURPOSE: The intraoral stent (IOS) is an individualized mouth opening device that can be used during radiotherapy (RT) for head and neck cancer to prevent unnecessary irradiation to normal tissues. The purpose of the present study was to compare the severity of oral mucositis (OM) between patients using and not using an IOS during RT for maxillary and nasal cavity cancer. PATIENTS AND METHODS: We designed and implemented a retrospective cohort study. The study sample included patients with maxillary and nasal cavity cancer who had undergone RT. The primary predictor variable was IOS application, and the outcome variable was the grade of OM. RESULTS: The IOS group included 18 patients with an IOS and the control group, 16 patients without an IOS. The parameters of the dose-volume histogram included the median dosage covering 1 mL (D1mL) for the tongue and the mean dosage. The D1mL (36.2 vs 65.4 Gy) and mean dosage (4.9 Gy vs 25.9 Gy) were both significantly lower in the IOS group than in the control group (P < .005). The incidence of OM using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0, were significantly different between the oral stomatitis grade and the use of an IOS (P = .028). A significant difference was found in opioid use between the IOS and control groups (P = .009). CONCLUSIONS: The use of an IOS decreased the radiation dosage to the tongue, the grade of OM, and opioid usage during RT.

RESUMO

Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor that combines the histologic features of ameloblastoma with those of cytologic atypia. The standard treatment for this lesion is wide local excision. Proton beam therapy (PBT) can deliver high irradiation doses to the target and avoid irradiation to surrounding normal tissues, but no reports of PBT for AC have been published thus far. This report describes the case of a 70-year-old woman with a pathologic diagnosis of maxillary AC who refused surgical resection and received hypofractionated PBT at a total dose of 69 Gy in 23 fractions. She has been alive for more than 5 years after PBT without any evidence of recurrence and side effects. This is the first reported case of successful treatment after curative radiation therapy for maxillary AC.

RESUMO

PURPOSE: Lymph node ratio (LNR), defined as the ratio of positive resected lymph nodes (LNs) to the total number of resected LNs, predicts survival for some solid tumors. This study investigated the value of LNR in the prognosis and postsurgical management of oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS: The authors designed a retrospective cohort study and enrolled a sample of patients who were diagnosed with OSCC and treated by neck dissection. The predictor was LNR and the outcome variable was overall survival (OS). Other variables were dissection type, postsurgical management, number of positive LNs, pN stage, nodal disease area, extracapsular spread, perineural invasion, vascular invasion, and lymph duct invasion. Differences in OS rate were analyzed by log-rank test. A Cox proportional hazards model was used to adjust for the effects of potential confounders. Differences with a P value less than .05 were considered statistically significant. RESULTS: In 95 patients with OSCC, the LNR cutoff value for predicting overall OS was 0.04 (area under the curve, 0.705; P = .010). There was a significant difference in OS when patients were stratified according to LNR (rate for low LNR, 90.5%; rate for high LNR, 68.8%; P = .014). Univariate analyses showed close correlations between OS and LNR, pT stage, number of positive LNs, and nodal disease area (levels IV and V). Cox multivariate analysis identified LNR (hazard ratio [HR] = 2.889; 95% confidence interval [CI], 1.032-8.087; P = .043) and area of nodal disease (levels IV and V; HR = 5.149; 95% CI, 1.428-18.566; P = .012) as independent predictive factors for OS. OS differed significantly between the high-LNR and low-LNR groups treated by surgery alone (P = .027). CONCLUSIONS: As a predictive factor, high LNR (>0.04) was associated with decreased survival, and intensive adjuvant therapy could improve the prognosis for patients with high LNR.

RESUMO

PURPOSE: The efficacy and safety of indomethacin (IM) oral spray (OS) as a pain control therapy for oropharyngeal mucositis due to anticancer chemo- and radiotherapy were assessed in patients with head and neck carcinomas and haematological tumours. METHOD: We observed 35 patients (male/female, 20/15; 53 ± 17 years) with oropharyngeal mucositis who were treated with IM-OS preparation for pain relief at University of Tsukuba Hospital, Japan. Analgesic effects were assessed using the six-grade face scale for pain in 28 patients at the start of IM oral spray treatment. Systemic exposure was assessed by determining urinary excretions of IM in seven patients. RESULTS: Pain relief was achieved in 26 (93%) patients at 25 (5-60) min after applying the IM-OS preparation (15.6 ± 3.4 µg/kg) and analgesic effects were maintained for 120 (10-360) min. The pain was significantly decreased after using the spray (3.6 ± 0.7 vs. 2.4 ± 0.9, p < 0.01). Moreover, urinary IM excretion rates after applying the IM spray preparation were 1.8 ± 0.8% of the IM oral spray dose (130.5 ± 77.7 µg/kg/day), which was markedly lower than that following oral administration of IM (60%). No adverse events were observed following application of the spray. CONCLUSIONS: The present IM spray is an effective and safe preparation for pain relief and can be used as an alternative therapeutic option for oropharyngeal mucositis in cancer patients.

RESUMO

BACKGROUND: Abnormal miRNA expression was recently implicated in the metastasis of oral squamous cell carcinoma (OSCC) and with a poor prognosis. The initiation of the invasion-metastasis cascade involves epithelial-mesenchymal transition (EMT). Our aim was to clarify how miRNA, especially miR-155-5p misexpression contributes to OSCC metastasis through EMT. METHODS: We collected tumor samples from 73 subjects with OSCC. The samples were analyzed by quantitative reverse-transcription polymerase chain reaction (qRT-PCR), and correlations between miR-155-5p levels and clinical characteristics were investigated. OSCC cell lines were analyzed by miRNA microarray and by transfection with a miR-155-5p mimic or inhibitor, followed by proliferation and wound-healing migration assays. qRT-PCR analyses of EMT makers in cells transfected with miR-155-5p inhibitor were performed. RESULTS: We found high miR-155-5p expression in tissue samples from subjects with OSCC that had metastasized to cervical lymph nodes. HSC-3 cells also strongly expressed miR-155-5p. The epithelial marker E-cadherin was strongly expressed in HSC-3 cells transfected with miR-155-5p inhibitor, and we observed elevated SOCS1 and decreased STAT3 expression in these cells. CONCLUSIONS: Our results suggest that miR-155-5p causes OSCC to metastasize, and could serve as a novel therapeutic target for OSCC.

RESUMO

OBJECTIVE: To assess the correlation between MR imaging (MRI) of parotid glands with X-ray sialography, histopathology of the labial salivary glands, and salivary secretion, in patients with secondary Sjögren's syndrome (SS) associated with rheumatoid arthritis (RA). METHODS: Non-contrast MRI of the parotid glands was performed in 13 secondary SS patients associated with RA who satisfied the revised Japanese diagnostic criteria for SS (1999), and the ACR/EULAR classification criteria for RA (2010). The MRI findings were classified according to the degree of high-intensity signal on T1-weighted images (T1WI) and short inversion time inversion recovery (STIR) images into five grades (0-4), using the modified Nagasaki University grading method. The results of MRI grading were compared with the Rubin and Holt staging of X-ray sialography (0-4), the Greenspan grading of labial salivary gland histopathology (0-4), and salivary secretion by the gum test (ml/10 min). RESULTS: All 13 patients were females, with a mean age of 50.2 ± 11.3 years. According to the MRI grading, 3 patients were Grade 1, 5 were Grade 2, 5 were Grade 3, and none was Grade 0 or Grade 4. The mean stage by X-ray sialography was 1.7 ± 1.0, the mean grade by histopathology was 2.4 ± 1.2, and the mean volume of salivary secretion was 9.7 ± 3.9 ml. The MRI grading correlated significantly with the Rubin and Holt staging and Greenspan grading (P < 0.01 each, Spearman's rank correlation), and significantly and inversely with the results of the gum test (P < 0.05). CONCLUSION: The results suggest that MRI of the parotid glands is a useful noninvasive tool for evaluating destruction and inflammation in the salivary glands.

RESUMO

The cytoplasmic regulatory protein p62 (Sequestosome 1/A170) is known to modulate various receptor-mediated intracellular signaling pathways. p62 deficiency was shown to result in mature-onset obesity in mice, but the mechanisms underlying this abnormality remained unclear. Here we report that hyperphagia due to central leptin resistance is the cause of obesity in p62(-/-) mice. We found that these mice show hyperphagia. Restriction of food to the amount eaten by wild-type mice prevented excess body weight gain and fat accumulation, suggesting that overfeeding is the primary cause of obesity in p62(-/-) mice. Brain-specific p62 deficiency caused mature-onset obesity to the same extent as in p62(-/-) mice, further supporting a neuronal mechanism as the major cause of obesity in these mice. Immunohistochemical analysis revealed that p62 is highly expressed in hypothalamic neurons, including POMC neurons in the arcuate nucleus. Central leptin resistance was observed even in young preobese p62(-/-) mice. We found a defect in intracellular distribution of the transcription factor Stat3, which is essential for the action of leptin, in p62(-/-) mice. These results indicate that brain p62 plays an important role in bodyweight control by modulating the central leptin-signaling pathway and that lack of p62 in the brain causes leptin resistance, leading to hyperphagia. Thus, p62 could be a clinical target for treating obesity and metabolic syndrome.

RESUMO

This study presents a rare case of an Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) co-existing with medication-related osteonecrosis of the jaw (MRONJ) in the mandible of a 54-year-old Japanese man who complained of painful swelling of the left mandibular gingiva over the past three months. The patient had a history of methotrexate (MTX) and bisphosphonates (BPs) use. Intraoral examination revealed a 35 mm large ulcerative lesion with marginal gingival swelling and bone exposure on the left side of the mandible. A biopsy was performed, confirming the diagnosis of EBVMCU with MRONJ. Due to the enlargement of the bone exposure, marginal resection of the mandible was performed under general anesthesia as a treatment for residual MRONJ. At the two-year follow-up, no evidence of recurrence was observed.

RESUMO

BACKGROUND: The submandibular gland (SMG) is sacrificed during neck dissection in patients undergoing curative surgery for oral squamous cell carcinoma (OSCC). This may cause a decrease in the production of saliva and result in xerostomia. PURPOSE: This study aimed to determine the incidence, invasion patterns, risk factors, and prognosis of SMG involvement in OSCC. METHODS: The primary predictor variable in this study was SMG involvement, and the secondary predictor was prognosis. MAIN FINDINGS: The primary outcome variables were patient characteristics and pathological results for extranodal extension (ENE), perineural invasion (PNI), and pN stage. Four out of 173 patients (2.23 %) showed SMG involvement. Of these cases, one (25 %) was from the primary lesion and three (75 %) were from the metastatic neck lymph nodes (LNs). The primary lesion was located on the lower gingiva, and the other three were from level-Ib LNs with ENE. The pathological PNI was observed in three of the four patients, and ENE was observed in three of the four patients. Preoperative CT and MR revealed SMG invasion and contact in two patients. There were significant differences in the ENE and pN stages between patients with and without SMG involvement (P<0.05). There was a significant difference in the overall survival between patients with (25.0 %) and without (71.5 %) SMG involvement (P = 0.011). CONCLUSIONS: SMG involvement was associated with ENE, pN stage, and poor prognosis.

RESUMO

Elective neck dissection (END) is recommended for the management of patients with oral squamous cell carcinoma (OSCC) because of the risk of occult metastasis (OM). We hypothesized that some factors predict poor prognosis regardless of a cN0 END. This study aimed to investigate the predictors of OM and prognostic factors in patients with cN0 OSCC who underwent supraomohyoid neck dissection (SOHND). A retrospective cohort study design was created and implemented. The primary predictive variables in this study were OM and risk factors for poor prognosis after SOHND. A Cox proportional hazard model was used to adjust for the effects of potential confounders on the risk factors for poor prognoses. Among 86 patients with OSCC, OMs were observed in 9 (10.5%). The neutrophil-to-lymphocyte ratio (NLR) and vascular invasion are good markers for detecting OM. A Cox multivariable analysis identified two independent predictors of overall survival: pathologic node (pN) and laterality of END. An independent predictive factor for disease-free survival, the surgical margin, was also identified in this study. According to the pN classification, pN1 patients had a worse survival rate than pN2 patients. Therefore, in the case of pN1, regardless of being cN0, additional adjuvant therapy may be necessary.

RESUMO

BACKGROUND: Postoperative temperature dysregulation affects the length of hospital stay and prognosis. This study evaluated the factors that influence the occurrence of fever in patients after aortic valve replacement surgery. METHODS: Eighty-seven consecutive patients who underwent aortic valve replacement surgery were included. Patients' age, sex and body mass index; presence of diabetes mellitus; operation time; blood loss; blood transfusion volume; preoperative and postoperative laboratory findings; presence or absence of oral function management; and fever >38°C were retrospectively analysed through univariate and multiple logistic regression analyses. RESULTS: Among the variables, only diabetes mellitus status was significantly associated with fever ⩾38°C. Postoperatively, patients with diabetes mellitus were significantly less likely to develop fever above 38°C and a fever rising to 38°C. CONCLUSIONS: This study shows that the presence of comorbid diabetes mellitus decreases the frequency of developing fever >38°C after aortic valve replacement surgery.

RESUMO

PURPOSE: In gingival squamous cell carcinoma (GSCC), the association between survival and previous dental extraction (DE) is controversial. The purpose of this study was to investigate the prognosis for patients in whom GSCC was detected after DE was performed. PATIENTS AND METHODS: DE for GSCC tumor symptoms was performed in 19 patients before diagnosis (DE group) and not in 58 patients (non-DE group). The clinical features, characteristics, and prognosis were evaluated statistically between the 2 groups. RESULTS: The interval from DE to the first hospital visit was 1.1 to 97 weeks (median, 7.3 weeks). There was no significant difference in tumor status, node status, local recurrence, pathologically positive lymph nodes, or distant metastasis between the DE and non-DE groups. Bone invasion was observed radiographically in 6 patients with mandibular GSCC in the DE group (100%) and 13 in the non-DE group (68.4%). There was a significant difference in bone invasion between the DE and non-DE groups (P < .01). Segmental mandibulectomy was performed in 11 patients (84.6%) in the DE group and 21 patients (61.8%) in the non-DE group. Extent of resection tended to be larger for the DE group. The 5-year overall survival rate was 84.6% for the DE group and 65.8% for patients with mandibular GSCC in the non-DE group. For maxillary GSCC, the survival rates differed significantly between groups (33.3% in DE group and 73.7% in non-DE group). CONCLUSIONS: For mandibular GSCC, the resection field was appropriate for the extent of bone invasion after DE and the prognosis was similar to that in the non-DE group. For maxillary GSCC, a broad surgical field is suggested because of the potential for rapid spread in cancellous bony trabeculae.

RESUMO

We assessed the postoperative nasal form and symmetry after presurgical use of a Hotz plate (HP) in patients with unilateral complete cleft lip and palate (UCLP). The subjects were 28 infants with UCLP who underwent cheiloplasty. Of these subjects, 14 underwent presurgical orthopedic treatment using the HP (HP group) and 14 underwent the same treatment without the HP (non-HP group). Photographic records were obtained 1 and 6 months after cheiloplasty, and the results of anthropometric analysis were compared between the 2 groups. The nasal inclination and the ratio of the width of the nasal base to the total width of the nose were significantly improved in the HP group compared with the non-HP group at both postoperative time points. Thus, presurgical use of the HP significantly improved the nasal asymmetry and deformity in UCLP patients after primary cheiloplasty and nasal repair.

RESUMO

Primary intraosseous squamous cell carcinoma (PISCC) arising from dentigerous cysts (DCs) is rare. Herein, we present a rare case of a 35 year-old Japanese man with PISCC arising from a DC. Clinicians should be aware of the potential for malignant changes to SCC in asymptomatic DCs and should conduct follow-up. Moreover, histological examination of the entire specimen should be performed even if the lesion is suspected to be benign.

RESUMO

This study investigated the effect of postoperative deep sedation after oral cancer reconstructive surgery on the occurrence of early postoperative pneumonia and early postoperative delirium. We obtained medical records of 108 consecutive patients who underwent microvascular reconstructive surgery at Tsukuba University Hospital for oral cancer between January 2013 and December 2021. Forty-six of them woke soon after surgery. Ten of these forty-six patients were restless and required immediate sedation within 3 h after surgery. The comparison between sedation group and no sedation group revealed early postoperative pneumonia in the no sedation group; however, sedation was not related to early postoperative delirium. The preoperative albumin levels of patients with postoperative pneumonia were significantly different (p = 0.03) than those of patients without postoperative pneumonia. The performance status (p = 0.02), preoperative albumin level (p = 0.02), and age 75 years or older (p = 0.02) were significantly associated with postoperative delirium. Restless patients and those who could not be sedated experienced delirium and pneumonia. The risk of pneumonia was increased for patients who were difficult to sedate.

RESUMO

We report a case of tophaceous pseudogout that occurred in the temporomandibular joint (TMJ) and presented with skull base destruction. The patient was a 73-year-old woman, who complained of an obstructed ear sensation in December 2021. The otolaryngological examination was unremarkeable, and a computed tomography scan revealed a calcified lesion in the left TMJ. Suspected of having osteochondroma, the patient was brought to our hospital. She was performed tumor resection as much as possible under general anesthesia revealed nodular pseudogout. The patient refused to undergo total resection due to the necessary craniotomy and the risk of postoperative complications. Instead, the patient decided to undergo following-up. One year and 4 months have passed since the biopsy operation, but there is no tendency to re-increase.
