RESUMO
This survey was conducted to determine the head and neck cancer (HNC) treatment strategies followed by oncologists in Chinese hospitals. It was a questionnaire-based survey, conducted from October 2017 to January 2018 in 100 random tertiary hospitals in 21 cities of China to elicit information from oncologists on the management practices for treating HNC in China. A validated, structured questionnaire was used for formal investigation with oncologists. The questions regarding HNC types, treatment strategies used for locally advanced head and neck cancer (LA HNC) and recurrent/metastatic head and neck cancer (r/m HNC), diagnosis and prognostic factors were included. The results were presented as percentages. Among the 272 oncologists, 93.4% were from tertiary care hospitals, with 35.3% and 36.4% patients from radiotherapy (RT) and oncology department, respectively. Nasopharyngeal carcinoma was the most commonly treated type of HNC according to 65.1% oncologists. Patients aged >75 years have worse prognosis and 65% oncologists corroborated that age of the patients influences treatment decision. Most of the oncologists (77.6%) preferred chemotherapy (CT) + anti-epidermal growth factor receptor targeted therapy as the first-line therapy for r/m HNC. Approximately 95% of oncologists considered induction chemotherapy (ICT) to retain organ functions and tumor shrinkage and 43.4% preferred ICT followed by chemoradiotherapy or ICT combined with RT followed by targeted therapy for LA HNC. For the management of HNC, Chinese oncologists recommended ICT with RT and targeted therapy for LA HNC and CT regimen combined with targeted therapy for r/m HNC.

OBJECTIVE: Resectioning of giant maxillofacial tumors has been shown to cause facial depression deformity, representing a persistent challenge for surgeons. Here, the authors review their experience using autologous free fat grafts to repair total parotidectomy defects. This review aims to encourage the surgical field to pay more attention to this century-old treatment technique. METHODS: Patients were included who underwent free fat transfer for tissue reconstruction after total parotidectomy at the Affiliated Stomatology Hospital of China Medical University between 2012 and 2018. Patients with bleeding disease or postoperative follow-up less than 6 months were excluded. RESULTS: Twenty-three patients between the ages of 35 and 68 were included in this analysis. Ten patients (6 males, 4 females) underwent fat grafting at the time of total parotidectomy, and a control group of 13 patients (9 males, 4 females) underwent total parotidectomy without correction of concave deformities. There were significant differences between fat graft group and control group in terms of age (44.9â±â9.0117 years versus 56.385â±â8.9586 years; Pâ=â0.006), Frey syndrome questionnaire score (1â±â0 versus 2.385â±â1.0439; Pâ=â0.00), blood loss (195.7â±â54.8777âmL versus 107.769â±â22.8916âmL; Pâ=â0.001), postoperative drainage (319.8â±â103.1803âmL versus 230.385â±â53.5701âmL; Pâ=â0.027), duration of postoperative drainage (122.4â±â23.8663âhours versus 90.462â±â22.2434âhours; Pâ=â0.003), and satisfaction questionnaire score (8.5â±â0.8498 versus 3â±â1.1547; Pâ=â0.00). The difference in operation time between the fat graft group and control group was not significant (417â±â108.0062âmin versus 351.538â±â91.7475âmin; Pâ=â0.131). CONCLUSION: Autologous free fat grafting resulted in more blood loss as well as an increased volume and duration of postoperative drainage. Remarkably, however, patients had superior satisfaction, lower Frey syndrome scores, and similar operation times with use of free fat grafting after parotidectomy. The authors recommend such grafting be utilized to repair concave deformities secondary to total parotidectomy.

BACKGROUND: The purpose of this study was to investigate the reliability and outcome of using the transverse cervical vessel (TCV) as a recipient vessel for microvascular reconstruction in patients whose vessels in the neck region are unavailable because of previous surgery or radiotherapy. METHODS: Between January 2012 and August 2014, secondary head and neck reconstruction was performed using the TCV as a recipient vessel in eight patients who had undergone previous neck dissection and radiation therapy (n = 5). Five patients had a recurrent carcinoma, one had undergone an operation for scar release and two had been treated surgically for a second primary cancer. The anterolateral thigh flap (ALT), anteromedial thigh flap (AMT), and fibular flap were used for the reconstruction. Clinical data were recorded for each patient. RESULTS: All of the ipsilateral transverse cervical arteries were found to be free of disease. The second free flap was revascularized using the TCVs (n = 6) or the external (n = 1) or internal (n = 1) jugular vein. The free flaps used for the reconstruction included the ALT flap (n = 6), AMT flap (n = 2), and fibular flap (n = 1). All of the flaps survived without vascular events, and the patients healed without major complications. The mean follow-up time was 11 months. One patient died of distant metastases during follow-up. CONCLUSIONS: In patients who have previously undergone neck surgery with or without radiotherapy, the TCVs are reliable and easily accessible recipient vessels for microsurgical reconstruction in the oral and maxillofacial region. If the transverse cervical vein is unavailable, the internal or external jugular vein should be dissected carefully to serve as an alternative for microvascular anastomoses.

PURPOSE: Our goal was to evaluate whether elderly patients can benefit from free flaps. MATERIALS AND METHODS: The clinical information from the included patients was reviewed, and these patients were asked to complete the University of Washington Quality of Life, version 4, questionnaire. Comparisons of the different scales between the 2 groups were performed. RESULTS: The difference in the mouth-opening width before and after surgery did not differ significantly (P = .621) in the patients with and without free flap reconstruction. However, free flap placement tended to preserve the original mouth-opening width. No significant differences were found in recurrence-free survival or disease-specific survival between the 2 groups. The mean quality of life score of the 2 groups was 77.5 ± 10.4 and 72.1 ± 10.8. Significant differences were found in the chewing domain scores between the 2 groups (P = .039). Patients with free flap reconstruction tended to score better in the appearance and taste domains (P = .073 and P = .053, respectively); however, they required longer operative times, and longer postoperative hospital stays and incurred hospital costs. CONCLUSIONS: Free flap reconstruction did not benefit elderly patients in mouth-opening width or survival analyses; the only quality of life domain that was significantly improved in patients undergoing free flap reconstruction was chewing. Free tissue transfer should be cautiously suggested for elderly patients with advanced oral cancer.

PURPOSE: To assess the effectiveness of double mental V-Y island advancement flaps for total lower lip reconstructions. MATERIALS AND METHODS: During a 6-year period, from 2006 to 2012, total lower lip reconstruction was performed in 12 patients using double mental V-Y island advanced flaps. The resulting lip function and superiority of each flap were analyzed. To assess any cosmetic implications, patients were asked to answer the Appearance Domain section from the University of Washington Quality of Life Questionnaire at least 12 months after discharge from the hospital. RESULTS: All flaps survived completely and no short-term postoperative complications occurred. The mean follow-up time was 34.5 months (range, 15 to 69 months) and there was no recurrence of disease. All patients were capable of consuming a regular oral diet and no patients complained of an inability to eat in a public setting, drooling, or microstomia. The mean preoperative and postoperative open-mouth widths were 4.1 and 3.7 cm, respectively, and the mean reduced open-mouth width was 10%. The intercommissural width varied from 4.6 to 6.8 cm (mean, 5.5 cm). The mean postoperative 2-point discrimination was 11.2 mm (range, 9 to 13 mm). The mean score for the Appearance Domain section was 93.8 (range, 75 to 100). CONCLUSION: The mental V-Y island advancement flap reconstruction is a reliable procedure for total lower lip reconstruction.

BACKGROUND: Parotid gland metastasis in lung cancer is extremely rare, very few cases have been reported. CASE PRESENTATION: We report on the case of a 61-year-old Chinese male patient who presented with parotid swelling metastasizing from advanced lung cancer. We therefore performed an operation of partial parotidectomy with preservation of the facial nerve and advised the patient receive chemotherapy, however, the patient died four months later. CONCLUSION: Although it is extremely rare, a potential metastasis of lung cancer should not be ignored in the diagnosis of parotid tumor. Preoperative routine examination, such as a chest X-ray and lung computational tomography scan, may play an important role in differential diagnosis. The management of the metastatic tumor to the parotid gland was controversial however, despite combined treatment modalities, long-term survival was not attained.

Smoking is associated with oral cancer, and to adopt a more healthy lifestyle, increasing numbers of people are choosing to give up the habit. However, the occurrence of oral cancer in ever smokers is still apparent. In this study, we investigated the survival of ever smokers with oral squamous cell carcinoma compared with nonsmokers and current smokers with oral squamous cell carcinoma. A matched-pair study was performed between 2005 and 2012, which matched 66 ever smoker patients with oral cancer to both current smokers and never smokers: each ever smoker was matched with 1 never smoker and 1 current smoker. A Chi-squared test was used to evaluate the significance of the variables, and the Kaplan-Meier method was used to analyze the recurrence-free survival and disease-specific survival rates. The recurrence-free survival (P = 0.006) and disease-specific survival (P = 0.027) rates were worse for ever smokers compared with never smokers, but the former group shared a similar prognosis with current smokers. The matched-pair analysis showed that smoking was associated with an approximately 2-fold increase in the risk for recurrence and 5-fold increase in risk for disease-related death. Ever smokers and current smokers had a similar chance of recurrence and disease-related death, but ever smokers had a poorer prognosis than never smokers do and they tended to have a local recurrence. The recurrence-free survival and disease-specific survival rates did not differ between ever and current smokers, and smoking cessation did not affect the chance of recurrence and diseases-related death in ever smokers compared with current smokers.

OBJECTIVE: To compare the platysma flap with submental flap in terms of tumor and flap characteristics, operative properties and the functional outcomes. METHODS: A total of 65 patients presented with tumors of head and neck and underwent curative tumor resection with different neck dissections at the Department of Oromaxillofacial-Head and Neck Surgery, School of Stomatology of China Medical University; from March 2005 to December 2012 were included in the study. After radical tumor excision and neck dissection the resultant complex defects were reconstructed with either platysma flap or the submental flap. The extent of surgical resection, the type of neck dissection and choice of flap reconstruction was at the discretion of the surgical team. The functional outcomes, operative time and characteristics of both platysma and submental flaps were compared and the statistical tests of significance were applied accordingly. RESULTS: The mean age was 60 years. The complex facial defects of 30 patients were reconstructed with platysma flap and of 35 patients with submental flap. Mean operation time of submental flap including flap harvesting (5.58±1.96hrs) was shorter than platysma flap (6.2±1.4hrs). The majority of the flaps (88-93%) were taken successfully in both groups. Submental flap was associated with significantly higher patients' satisfaction regarding acceptable functional outcomes (p-value 0.027). The mean reduction in mouth opening was significantly smaller in platysma group (0.37 ±0.18cms) than the submental group (0.47±0.16). CONCLUSION: This study demonstrates that both platysma and submental flap techniques can be used for the reconstruction of complex facial defects with the acceptable functional outcome. The platysma flap can be harvested to medium size defects up to 70cm(2) with good mouth opening. The submental flap is simpler, faster with a wider range of application and more acceptable functional outcomes.
RESUMO
PURPOSE: The aim of the present study was to evaluate the quality of life (QoL) of patients with oral cancer who had undergone resection of the tongue and floor of the mouth and reconstruction with the pectoralis major flap. MATERIALS AND METHODS: The present study assessed 21 patients who had undergone pectoralis major flap reconstruction using the University of Washington QoL, version 4, questionnaire. A nonparametric Mann-Whitney U test was used to analyze the data. RESULTS: Of the 12 disease-specific domains, the best 3 scores from the patients were for pain, saliva, and anxiety, and the worst 3 scores were for taste, chewing, and swallowing. The mean UW-QoL composite score was 73.4. Swallowing was considered to be the most important issue within the previous 7 days, followed by chewing and speech. Those patients who had undergone wider excision had poorer speech. CONCLUSIONS: A significant effect was found on the QoL of patients with oral cancer who had undergone resection of the tongue and floor of the mouth with pectoralis major flap reconstruction.

BACKGROUND: The ideal method for buccal defects should provide good outcome of both function and appearance; our goal is to highlight the reliability of radial forearm flap in buccal reconstruction. METHODS: A retrospective study was conducted. From 2005 to 2012, 20 radial forearm flaps were used to repair the defects. We analyzed the superiority and reliability of the flap; in addition, we reviewed some related literature and made a comparison between radial forearm flap and platysma flap. RESULTS: All radial forearm flaps totally survived, but two flaps suffered venous obstruction, hematoma, respectively. Radial forearm flap preserved the original interincisal distance well. In our follow-up, all patients had sufficient mouth-opening width (mean: 4.3 cm). CONCLUSION: Radial forearm flap is a reliable method for buccal defect reconstruction.

BACKGROUND: Platysma myocutaneous flap (PMF) is a generally used technique for defect reconstruction after an oral cancer resection. The aim of the study is to present our experience using vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction. METHODS: A retrospective review of the medical records of 54 patients who underwent vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction was performed. A comparison between PMF that sacrificed and that preserved the facial vessels was made, and we also compared PMF that sacrificed the facial vessels with radial forearm free flap (RFFF). Statistics concerning the patients' clinical factors were gathered. RESULTS: The mean age of the 54 patients who underwent PMF that sacrificed the facial artery and vein was 62.0 ± 10.98 years. The co-morbid disease rate of PMF was 53.7%. The flap size ranged from 12 × 5.5 cm to 7 × 5 cm. Survival of the flap was found in all of the cases, with partial necrosis in four cases (7.4%) and total loss in none of the cases. The operation time was 5.7 ± 1.17 h. The complication and success rates were 27.8% and 92.6%, respectively. The 3-year and 5-year survival rates were 77.8% (21/27) and 69.23% (9/13), respectively. The majority of the patients (87.0%) in our series were satisfied with the results of the surgery. There was no significant difference between PMF that sacrificed or that preserved the facial vessels, both in success rate (P = 1) or complication rate (P = 0.72). The patients in the PMF group were older than the patients in the RFFF group (P = 0.011), the operation time was shorter (P < 0.001), and the co-morbid disease rate was higher (P = 0.002). Although the complication rate of PMF (15/54, 27.8%) was higher than that of RFFF (2/34, 5.9%) (P = 0.011), their success rates were similar (92.6%, 94.1%) (P = 1.00). CONCLUSIONS: Vertical PMF that sacrifices the facial artery and vein has specific advantages including in ease preparation and limitations. This technique may provide an effective method for intraoral reconstruction. Our experience in handling the flap may contribute to the success rate.

We reported 1 case of primary Sjögren syndrome in a child. The patient complained recurrent submandibular inflammation for more than 2 years without apparent sicca presentations, and Schirmer test resulted negative. However, ultrasound showed hypoechoic areas in the gland, laboratory tests reported the positivity of Sjögren's syndrome A antigen and Sjögren's syndrome B antigen, and biopsy presented periductal lymphocytic infiltration. Therefore, a diagnosis of primary Sjögren syndrome was conducted. Treatment of it required a multidisciplinary team.

This study investigated the quality of life in patients younger than 40 years with tongue squamous cell carcinoma. We used the University of Washington Head and Neck Quality of Life scale to compare the quality of life outcomes between young and old patients. Cases were patients younger than 40 years who were treated for anterior tongue squamous cell carcinoma. Controls were patients older than 40 years who were matched to the cases regarding diagnosis, sex, and TNM classification. Two controls were matched for each case; thus, 21 cases and 42 controls were selected. Twenty-one of 33 questionnaires (63.6%) were returned. The median follow-up duration was 3.7 years (range, 1-12 y). In the group of young patients, the best-scoring domains were pain, chewing, and swallowing, whereas the lowest scores were for appearance, mood, and anxiety. Young patients (40 years or younger) reported better function, notably regarding activity, recreation, shoulder, taste, and saliva compared with the old patients with anterior tongue squamous cell carcinoma. The patients younger than 40 years tend to have a good quality of life. Most of them were not significantly affected by pain. Quality of life should be used as part of our treatment of anterior tongue squamous cell carcinoma.

Our purpose was to evaluate the feasibility of radial forearm free (RFF) flap, platysma myocutaneous (PM) flap, and anterolateral thigh (ALT) flap in buccal reconstruction. This study consisted of 56 patients who were categorized into 3 groups. The Student t test was used to analyze the variables. Patients in group platysma flap were significantly older, the dissection of platysma flap was easier, and the defect was significantly smaller than those in group radial forearm flap and group ALT flap. The reduction in the widths of mouth opening between group PM, group RFF, and group ALT were compared. However, the reduction of mouth-opening widths in group RFF and group ALT was significantly less than that in group PM. Platysma myocutaneous flap may be more suitable in patients with small to middle-size defect and poor status, although the flap cannot achieve a reliable result; anterolateral thigh flap and radial forearm flap can preserve the interincisal distance well even for large buccal defect, but it takes more time and skills in the operation.

The purpose of this study was to introduce a novel individualized flap design method for large anterior floor of the mouth (AFOM) defect reconstruction, review experience with the use of this flap design method for large AFOM defect reconstruction, and assess its functional results. A retrospective study of patients who received large AFOM defect reconstruction with free flaps was conducted. There was a cohort of patients who were treated using the novel individualized flap design method and a cohort without flap design. Functional outcomes were evaluated with appropriate scales. Outcomes were analyzed, and a p-value <0.05 was considered significant. 22 patients received the individualized flap design, while 21 patients were treated without a special flap design. All flaps survived. All free flaps harvested with the novel individualized flap design method better matched AFOM defects. Relative to patients without flap design, patients in the novel individualized flap design group showed significant improvement in speech intelligibility (p = 0.036) and swallowing function (p = 0.019). Within the limitation of the study it seems that large AFOM defect reconstruction with the novel individualized flap design method can not only cover and close the wound to avoid oral-neck fistulae, but also maintains tongue mobility to achieve better functional outcomes than in patients without flap design.
RESUMO
BACKGROUND: To achieve improved functional outcomes in subtotal tongue reconstruction, a flap design with sufficient volume and appropriate shape is necessary. In this study, we introduce an "Individualized and Convenient Tongue Model" (ICTM) for flap design in subtotal tongue reconstruction. METHODS: By studying the anatomical morphology of the tongue, we found a similar geometry within the dorsum and body of the tongue as well as the mouth floor. This can be used to create an ICTM through folding and splicing. We can simulate tongue defects in the ICTM and transform defect shapes into guide plates for flap design. In this study, fifty-eight patients requiring subtotal tongue reconstruction were randomly divided into two groups: an ICTM group (35 patients) and a conventional group (31 patients). In the ICTM group, we individually designed profunda artery perforator flaps (PAPFs) or anterolateral thigh flaps (ALTFs) using the ICTM method. In the conventional group, the flap was designed according to the surgeon's clinical experience. Patient demographics, operative and follow-up data were recorded. Swallowing, speech intelligibility, and cosmetic results were assessed using appropriate scales. RESULTS: All flaps survived, although there were no significant differences in tumor size, operation time, flap size, and complication rate compared to the conventional group. Patients in the ICTM group had significantly improved speech intelligibility (p = 0.019), cosmetic appearance (p = 0.009), and swallowing ability (p = 0.003). CONCLUSIONS: The ICTM technique is an effective and convenient solution for subtotal tongue reconstruction that provides an individualized flap design and improves functional outcomes compared to the conventional design.

PURPOSE: This study aimed to investigate the impact of CC chemokine receptor 7 (CCR7) on the recruitment and polarization of tumor-associated macrophages (TAMs) in oral squamous cell carcinoma (OSCC). METHODS: We analyzed CCR7 expression pattern, clinicopathological significance, and its association with M2 macrophage infiltration in OSCC by bioinformatic methods. Small interfering RNA (siRNA) was utilized to silence CCR7 in OSCC cells. Conditioned media (CM) was harvested from transfected OSCC cells to establish a co-culture model of THP-1 derived macrophages and OSCC cells. Transwell assay and cell adhesion assay were performed to examine the effect of CCR7 on macrophages recruitment and adhesion. Cytoskeleton was labelled by phalloidin to observe macrophage morphological changes. Moreover, phenotypic alteration of macrophages was measured using quantitative real-time PCR (qRT-PCR), flow cytometry, and immunofluorescence (IF) staining. Ultimately, recombinant human CCL19 and CCL21 were added into the medium of THP-1 derived macrophages to explore their effects on polarization in vitro. RESULTS: In OSCC patients, the overexpression of CCR7 positively correlated with lymph node metastasis and M2 macrophage infiltration. Macrophage not only exhibited enhanced migration, invasion and adhesion abilities, but also appeared more spindle and branched in vitro when treated with CM from OSCC cells. However, these phenomena were abrogated with knockdown of CCR7. We also discovered that inhibition of CCR7 in OSCC cells suppressed TAMs polarization to an M2 phenotype. In addition, recombinant human CCL19 and CCL21 promoted macrophage M2-polarization in vitro. CONCLUSION: CCR7 in OSCC cells promoted recruitment and M2-polarization of THP-1 derived macrophages in vitro by regulating production of CCL19 and CCL21.
RESUMO
Purpose: This study aimed to investigate the biological roles of fibronectin 1 (FN1) in head and neck squamous cell carcinoma (HNSCC) and its effects on macrophage M2 polarization. Methods: We analyzed FN1 expression pattern and examined its clinical relevance in HNSCC progression by bioinformatic analysis. Small interfering RNA (siRNA) was utilized to silence FN1 in HNSCC cells. Cell counting kit-8 (CCK-8) assay, colony formation assay, Transwell assay and wound healing assay were performed to reveal the effect of FN1 on malignant behaviors of HNSCC cells. Moreover, a co-culture model of macrophages and HNSCC cells was established to investigate whether FN1 induce macrophage M2 polarization. Finally, we used bioinformatic methods to explore the possible FN1-related pathways in HNSCC. Results: FN1 is significantly overexpressed in HNSCC patients and has been obviously correlated with higher pathological stage and poor prognosis. Downregulation of FN1 suppressed the proliferation, migration and invasion of HNSCC cells, and inhibited macrophage M2 polarization in vitro. In addition, "PI3K-Akt" and "MAPK" signaling pathways may be involved in the malignant process of FN1 in HNSCC. Conclusion: The overexpression of FN1 promotes HNSCC progression and induces macrophages M2 polarization. FN1 may serve as a promising prognostic biomarker and therapeutic target in HNSCC.
RESUMO
BACKGROUND: The large defects resulting from head and neck tumour surgeries present a reconstructive challenge to surgeons. Although numerous methods can be used, they all have their own limitations. In this paper, we present our experience with cervicofacial and cervicothoracic rotation flaps to help expand the awareness and application of this useful system of flaps. METHODS: Twenty-one consecutive patients who underwent repair of a variety of defects of the head and neck with cervicofacial or cervicothoracic flaps in our hospital from 2006 to 2009 were retrospectively analysed. Statistics pertaining to the patients' clinical factors were gathered. RESULTS: Cheek neoplasms are the most common indication for cervicofacial and cervicothoracic rotation flaps, followed by parotid tumours. Among the 12 patients with medical comorbidities, the most common was hypertension. Defects ranging from 1.5 cm × 1.5 cm to 7 cm × 6 cm were reconstructed by cervicofacial flap, and defects from 3 cm × 2 cm to 16 cm × 7 cm were reconstructed by cervicothoracic flap. The two flaps also exhibited versatility in these reconstructions. When combined with the pectoralis major myocutaneous flap, the cervicothoracic flap could repair through-and-through cheek defects, and in combination with a temporalis myofacial flap, the cervicofacial flap was able to cover orbital defects. Additionally, 95% patients were satisfied with their resulting contour results. CONCLUSIONS: Cervicofacial and cervicothoracic flaps provide a technically simple, reliable, safe, efficient and cosmetic means to reconstruct defects of the head and neck.

In this report, we present a case with floor of mouth squamous cell carcinoma who underwent wide excision of tumor, a marginal mandibulectomy and bilateral selective neck dissections. A 7 cm × 4 cm fasciocutaneous flap based on a posterior tibial artery perforator (PTAP) from the left posterior leg was harvested to reconstruct a floor of the mouth defect. The donor-site defect was closed primarily. The flap survived in its entirety. No donor or recipient site complications occurred. The patient tolerated a regular diet at 3-month follow-up with normal speech and leg function. To our knowledge, there has been no previous report on the use of the PTAP flap for floor of mouth reconstruction. Our experience has shown the PTAP flap could be one of options for small defects.
