ABSTRACT

Introducción. El carcinoma epidermoide cutáneo (CEC) es la segunda neoplasia cutánea más frecuente después del carcinoma basocelular. La incidencia del CEC ha aumentado de forma considerable durante los últimos 20 años y predicen un incremento en la próxima década. La mayoría de los CEC están localizados y se resuelven habitualmente mediante la extirpación quirúrgica u otros procedimientos locales. El uso del músculo temporal es una alternativa quirúrgica para corregir el defecto periorbitario tras la extirpación del CEC. Objetivo. Evaluar el resultado de la cobertura del músculo temporal en la corrección del defecto periorbitario. Material y métodos. Se presenta un caso quirúrgico de un paciente masculino, 62 años, que presenta una gran lesión tumoral que compromete el globo ocular, región orbitaria y periorbitaria izquierda, acompañado de dolor, anemia, astenia y pérdida ponderal de aproximadamente 20 libras. Con una evolución de 6 años. Conclusión. El uso del músculo temporal es una alternativa eficaz en la reconstrucción de lesiones craneofaciales, que ha sido utilizado por más de 100 años.


Introduction. Skin epidermoid carcinoma (SEC) is the second most common skin neoplasm after basal cell carcinoma. The incidence of SEC has increased considerably over the past 20 years and predicts an increase over the next decade. Most SECs are located and usually resolved by surgical removal or other local procedures. The use of the temporal muscle is a surgical alternative to correct the peri-orbital defect after removal of the SEC. Objective. To evaluate the result of temporal muscle coverage in the correction of the peri-orbital defect. Material and methods. There is a surgical case of a male patient, 62 years old who has a large tumor injury that compromises the eyeball, orbital region and left periorbital. Accompanied by pain, anemia, asthenia, and weight loss approximately 20 pounds. With an evolution of 6 years. Conclusion. The use of the temporalis muscle is an effective alternative in the reconstruction of craniofacial lesions that has been used for more than 100 years

ABSTRACT

Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

ABSTRACT

Objective: To evaluate the efficacy and safety of neoadjuvant chemotherapy combined with programmed death-1 (PD-1) antibody in operable, borderline or potentially resectable locally advanced esophageal squamous cell carcinoma(ESCC) in the real world. Methods: The study retrospectively analyzed 28 patients with operable or potentially resectable locally advanced ESCC patients treated with preoperative chemotherapy combined with PD-1 inhibitor in Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School from April 2020 to March 2021. According to the clinical TNM staging system of the 8th edition of the American Joint Committee on Cancer, there were 1, 15, 10, 1 and 1 case of stage Ⅱ, Ⅲ, ⅣA, ⅣB and unknown stage respectively. The treatment was two cycle of dual drug chemotherapy regimen including taxane plus platinum or fluorouracil combined with PD-1 antibody followed by tumor response assessment and surgery if the patient was eligible for resection. Results: Of the 28 patients, 1, 2, 3 and 4 cycles of chemotherapy combined with PD-1 antibody treatment completed in 1, 21, 5, and 1 patient, respectively. Objective response rate (ORR) was 71.4% (20/28), and disease control rate (DCR) was 100% (28/28). The incidence of adverse events exceeding grade 3 levels was 21.4% (6/28), including 3 neutropenia, 1 leukopenia, 1 thrombocytopenia and 1 immune hepatitis. There was no treatment-related death. Of the 23 patients underwent surgery, R0 resection rate was 87.0% (20/23), 13 patients had down staged to the T1-2N0M0 I stage, the pCR rate was 17.3% (4/23), and the pCR rate of primary tumor was 21.7% (5/23). Four patients received definitive chemoradiotherapy. One patient rejected surgery and other treatment after achieved PR response. Conclusion: Neoadjuvant chemotherapy combined PD-1 inhibitor is safe and has high efficacy in operable, borderline or potentially resectable locally advanced ESCC, and it is a promising regimen.

ABSTRACT

OBJECTIVE@#To explore the effectiveness of folded transverse superficial epigastric artery perforator flap in repairing the large penetrating defect after buccal carcinoma resection.@*METHODS@#Between January 2019 and June 2021, 12 patients with buccal squamous cell carcinoma were treated. There were 6 males and 6 females with an average of 66.9 years (range, 53-79 years). The pathological stage was T3a-T4b, and the preoperative mouth opening was (3.08±0.46) cm. The disease duration ranged from 6 to 24 months, with an average of 15 months. After buccal carcinoma radical resection and neck lymph node dissection, the penetrating defects in size of 8 cm×6 cm to 16 cm×8 cm and in depth of 0.5-1.5 cm were remained. The transverse superficial epigastric artery perforator flap in size of 8 cm×6 cm to 14 cm×8 cm were harvested and folded to repair the penetrating defects. The donor site was sutured directly.@*RESULTS@#All 12 skin flaps survived after operation, and the wounds healed by first intention. No internal or external fistula complications occurred. All incisions at the recipient site healed by first intention. All patients were followed up 12-18 months (mean, 14 months). There was no obvious abnormality in the color and texture of the flap, the oral and facial appearances were symmetrical, and there was no obvious swelling in the cheek. At last follow-up, the patient's mouth opening was (2.89±0.33) cm, which was not significantly different from that before operation ( t=1.879, P=0.087). The subjective satisfaction scores of 12 patients were 6-8 points, with an average of 7.3 points. Significant scars remained at the donor site but concealed in location.@*CONCLUSION@#The folded transverse superficial epigastric artery perforator flap can be used as a surgical method for repairing large penetrating defects after the buccal carcinoma resection, with a good recovery of facial appearance and oral function.

ABSTRACT

OBJECTIVE@#To summarize the effectiveness of the temporal island flap pedicled with the perforating branch of zygomatic orbital artery for repairing defects after periocular malignant tumor resection.@*METHODS@#Between January 2015 and December 2020, 15 patients with periocular malignant tumors were treated. There were 5 males and 10 females with an average age of 62 years (range, 40-75 years). There were 12 cases of basal cell carcinoma and 3 cases of squamous carcinoma. The disease duration ranged from 5 months to 10 years (median, 2 years). The size of tumors ranged from 1.0 cm×0.8 cm to 2.5 cm×1.5 cm, without tarsal plate invasion. After extensive resection of the tumors, the left defects in size of 2.0 cm×1.5 cm to 3.5 cm×2.0 cm were repaired with the temporal island flap pedicled with the perforating branch of zygomatic orbital artery via subcutaneous tunnel. The size of the flaps ranged from 3.0 cm×1.5 cm to 5.0 cm×2.0 cm. The donor sites were separated subcutaneously and sutured directly.@*RESULTS@#All flaps survived after operation and the wounds healed by first intention. The incisions at donor sites healed by first intention. All patients were followed up 6-24 months (median, 11 months). The flaps were not obviously bloated, the texture and color were basically the same as the surrounding normal skin, and the scars at recipient sites were not obviously. There was no complication such as ptosis, ectropion, or incomplete closure of the eyelids and recurrence of tumor during follow-up.@*CONCLUSION@#The temporal island flap pedicled with the perforating branch of zygomatic orbital artery can repair the defects after periorbital malignant tumors resection and has the advantages of reliable blood supply, flexible design, and good morphology and function.

ABSTRACT

La cavidad oral está continuamente expuesta a carcinógenos inhalados e ingeridos (tabaco y alcohol principalmente), y por lo tanto es el sitio más común para el origen de neoplasias en la región de la cabeza y el cuello.Para esta investigación, se realizó un estudio observacional descriptivo, de corte transversal, retrospectivo, de muestreo no probabilístico de casos consecutivos. Se incluyó a pacientes mayores de edad, con diagnóstico clínico y anatomopatológico de cáncer de cavidad oral.Así, se incluyó una serie de 17 casos de carcinoma escamocelular oral, 13 hombres (76 %) y 4 mujeres (24 %), donde la edad de los individuos osciló entre 32 y 73 años.El 65 % de los pacientes era fumador y el 71% refirió consumo de bebidas alcohólicas.La lengua fue la localización tumoral más frecuente, con el 71% de las personas que se encontraba en estadio IV, y con moderado grado de diferenciación histológica. Como conclusión, se determinó que la mayor parte de los pacientes de este estudio correspondían al sexo masculino de 50 a 70 años. Un alto porcentaje de los pacientes refería el hábito tabáquico, y mayor aún el consumo de alcohol. El subsitio más frecuentemente afectado es la lengua, en estadios avanzados y moderado grado de diferenciación.


INTRODUCTION: The oral cavity is continuously exposed to inhaled and ingested carcinogens (mainly tobacco and alcohol), and therefore it is the most common site for the origin of neoplasms in the head and neck region. METHODS: A descriptive, retrospective, observational study of non-probabilistic sampling of consecutive cases was carried out. Adult patients with a clinical and pathological diagnosis of oral cavity cancer were included. RESULTS: A series of 17 cases of oral squamous cell carcinoma was included, 13 men (76%) and 4 women (24%). The age of the individuals ranged between 32 and 73 years.65% of the patients were smokers, and 71% reported consumption of alcoholic beverages.The tongue was the most frequent tumor location, 71% were in stage IV, and with a moderate degree of histological differentiation. CONCLUSION: Most of the patients in this study were males between 50 and 70 years of age. A high percentage of patients reported smoking, and an even higher percentage of alcohol consumption. The most frequently affected subsite is the tongue, in advanced stages and a moderate degree of differentiation.

ABSTRACT

El tratamiento correcto de carcinoma escamoso avanzado requiere de un manejo multidisciplinar entre cirujanos, anatomopatólogos, radioterapeutas y radiólogos. Los protocolos están claros cuando nos hallamos ante una enfermedad localizada, sin embargo, cuando la enfermedad es metastática no existe evidencia científica de los pasos a seguir. Presentamos una paciente con un carcinoma escamoso del ano con una única metástasis cutánea metacrónica que fue tratada con cirugía y radioterapia posterior con buena respuesta.


The right therapy of anal cancer needs a multidisciplinary management of surgeons, pathologists, radiotherapists and radiologist. The treatment of squamous cell carcinoma of the anal canal is well-known when the patient presents a locally disease, nevertheless, there is a lack of information with the advanced anal cancer. We report a case of a 74-year-old woman with a solitary methachronical cutaneous metastasis of anal cancer which responded perfectly to surgery and radiotherapy.

ABSTRACT

Abstract Introduction: Posterior pharyngeal wall is the most rare subsite for hypopharyngeal carcinomas. Because of its rarity, there are few studies published in the literature specifically concerning posterior pharyngeal wall carcinoma. Objectives: To report our functional results in patients with the carcinoma of the posterior wall of the hypopharynx after surgical treatment by resection via a lateral or infrahyoid pharyngotomy approach, with the preservation of the larynx and reconstruction with a radial forearm free flap. Methods: The study included 10 patients who underwent surgery for a carcinoma of the posterior wall of the hypopharynx over a 6 year period. The associated postoperative morbidity was investigated and functional results were analyzed. Results: Nine patients had T3 lesions and one patient had a T2 lesion. The preferred approach to access the hypopharynx was a lateral pharyngotomy in 5 patients and lateral pharyngotomy combined with infrahyoid pharyngotomy in 5 patients with superior extension to oropharynx. The pharyngeal defects were reconstructed successfully with radial forearm free flaps. Four patients received adjuvant radiotherapy only, and 4 patients with N2b and N2c neck diseases received adjuvant chemoradiotherapy. The mean duration of hospitalization was 15.6 days (range, 10-21 days). All patients achieved oral intake in a median time of 74 days (range, 15-180). Decannulation was achieved in all patients and the median time fordecannulation was 90 (range, 21-300 days). The mean followup duration was 38.3 months (range, 10-71 months) and 8 patients survived. One patient died due to regional recurrence in the retropharyngeal lymph nodes and 1 patient died due to systemic metastasis. Conclusion: Primary surgery is still a very effective treatment modality for the carcinoma of the posterior wall of the hypopharynx and does not permanently compromise the swallowing and laryngeal functions if pharyngeal reconstruction is performed with a free flap.


Resumo Introdução: A parede posterior da faringe é o subsítio mais raro para carcinomas hipofaríngeos. Devido à sua raridade, há poucos estudos publicados na literatura especificamente sobre o carcinoma da parede posterior da faringe. Objetivo: Relatar nossos resultados funcionais em pacientes com carcinoma da parede posterior da hipofaringe após tratamento cirúrgico por ressecção via faringotomia lateral ou infra-hióidea, com preservação da laringe e reconstrução com retalho livre radial do antebraço. Método: O estudo incluiu 10 pacientes submetidos à cirurgia para carcinoma da parede posterior da hipofaringe por 6 anos. A morbidade pós-operatória associada foi investigada e os resultados funcionais foram analisados. Resultados: Nove pacientes apresentaram lesões T3 e um paciente apresentou lesão T2. Avia preferida para acessar a hipofaringe foi a faringotomia lateral em 5 pacientes e a faringotomia lateral combinada com a faringotomia infra-hióidea em 5 pacientes com extensão superior até a orofaringe. Os defeitos faríngeos foram reconstruídos com sucesso com retalhos livres radiais do antebraço. Quatro pacientes receberam apenas radioterapia adjuvante e 4 pacientes com doença cervical N2b e N2c receberam quimiorradioterapia adjuvante. A duração média da hospitalização foi de 15,6 dias (variação de 10 a 21 dias). Todos os pacientes retornaram à ingestão oral em um tempo médio de 74 dias (variação de 15 a 180). A decanulação foi possível para todos os pacientes e o tempo médio foi de 90 dias (variação de 21 a 300 dias). A duração média do seguimento foi de 38,3 meses (10 a 71 meses) e 8 pacientes sobreviveram. Um paciente foi a óbito devido a recorrência regional nos linfonodos retrofaríngeos e outro devido a metástase sistêmica. Conclusão: A cirurgia primária ainda é uma modalidade de tratamento muito eficaz para o carcinoma da parede posterior da hipofaringe e não compromete de forma permanente as funções de deglutição e da laringe se a reconstrução faríngea for feita com retalho livre.

ABSTRACT

Objective: To investigate the survival outcomes and prognostic factors of patients with salvage surgery for hypopharyngeal carcinoma after radiotherapy. Methods: A retrospective analysis was performed, including 26 patients treated in Ningbo Medical Center Lihuili Hospital between January 2010 and December 2015. All patients were males, aged 48-83 years, of whom 8 cases were local residual after radiotherapy alone, 8 cases were local recurrence after postoperative radiotherapy, 2 cases were residual of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after postoperative radiotherapy and 4 cases were recurrence of tracheal stoma. The salvage operations included: local resection, local resection with neck dissection, simple neck dissection, tumor resection of tracheostomy, and additional repair according to the defect. Chi square test was used for recurrence and metastasis analysis, Kaplan-Meier method for survival analysis, Log-rank test for univariate analysis, and Cox regression model for multivariate analysis. Results: The complication rate of salvage surgery was 23.1% (6/26). The recurrence rate was 65.4% (17/26) and the distant metastasis rate was 42.3% (11/26) in the 5-year follow-up after salvage surgery. Patient's age and tumor invasion extent were correlated with recurrence. Initial treatment, tumor persistence or recurrence after radiotherapy, recurrence location and tumor invasion extent were correlated with distant metastasis (all P<0.05). Overall, 3 year and 5 year survival rates were 42.3% and 23.1% respectively. Age, recurrence location, surgical margin and tumor invasion extent were related to prognosis (χ²=6.56, 10.68, 9.32, and 7.90 respectively, all P<0.05). Multivariate analysis showed that surgical margin and tumor invasion extent were independent risk factors for prognosis (OR (95%CI) = 3.19 (1.03-9.84), 14.37 (2.46-84.08), both P<0.05). Conclusion: Salvage surgery is the first choice for patients with recurrence after radiotherapy for hypopharyngeal carcinoma. Safe surgical margin should be ensured, especially in tumors invading muscle, bone tissue or lymph node capsule.

ABSTRACT

OBJECTIVE@#To investigate the characteristics of pathogen infection and to establish a prediction model of infections in oral squamous cell carcinoma patients undergoing surgery with free flap reconstruction.@*METHODS@#The retrospective cohort study consisted of 1 596 patients undergoing tumor resection and free flap reconstruction for oral squamous cell carcinoma from January 2018 to December 2020. According to the postoperative infection, the patients were divided into the infected group (n=154) and non-infected group (n=1 442). The characteristics of pathogens were analyzed in the infected patients. The primary outcome variable was postoperative infection, and Logistic regression was used to determine risk factors of the infection. The prediction model was established and the discriminatory accuracy of the model was evaluated using receiver operating characteristic (ROC) curve.@*RESULTS@#Totally 154 cases were infected in the 1 596 cases undergoing surgery with free flap reconstruction, and the infection rate was 9.65%. The most frequent sites of infection were the surgical wound and respiratory tract. A total of 268 pathogens were isolated and cultured, including 240 strains of Gram-negative bacteria, accounting for 89.55%, mainly Pseudomonas aeruginosa and Klebsiella pneumoniae; 23 strains of Gram-positive bacteria, accounting for 8.58%, mainly Enterococcus faecalis and Staphylococcus aureus; and 5 strains of fungi, accounting for 1.87%. The isolated Pseudomonas aeruginosa had high resistant rate to imipenem and meropenem, and was sensitive to antibiotics, such as ciprofloxacin. The isolated Staphylococcus aureus had high resistant rate to erythromycin and clindamycin, and was sensitive to vancomycin. According to the multivariate Logistic analysis, four independent variables were significantly associated with an increased risk of postoperative infection (P < 0.05): clinical N category≥1, the American Society of Anesthesiologists (ASA) grade ≥2, tracheotomy and length of hospital stay >13 d. The prediction model was established based on these factors and the expression of the risk prediction model was as follows: predicted probability value P=1/(1+e-a), a=-0.803+0.674×(clinical N category ≥1)+0.518×(the ASA grade ≥2)+0.918×(tracheotomy)+1.581×(length of hospital stay >13 d), Hosmer-Lemeshow χ2=10.647, P=0.223, the degree of fitting of the model was good. The area under the ROC curve was 0.818 and 95%CI of the model for predicting infection was 0.789-0.846.@*CONCLUSION@#Oral squamous cell carcinoma patients undergoing surgery with free flap reconstruction are prone to have a high incidence of postoperative infection and Gram-negative bacteria are the main pathogens causing an infection. The established prediction model is of good predictive effect. Rational antimicrobial use coupled with awareness of infection control measures is paramount to reduce the incidence of postoperative infection in the oral squamous cell carcinoma patients undergoing surgery with free flap reconstruction.

ABSTRACT

Objective: To explore the clinical effects of three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation in the treatment of wounds with skull defect after radical surgery of squamous cell carcinoma in the vertex. Methods: A retrospective observational study was conducted. From January 2010 to December 2019, 5 patients with squamous cell carcinoma in the vertex accompanied with skull invasion who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the Second Affiliated Hospital of Air Force Medical University, including four males and one female, aged 50 to 65 years. The original lesion areas ranged from 5 cm×4 cm to 15 cm×8 cm. The titanium mesh was prefabricated via three-dimensional technic based on the result the scope of skull resection predicted with computerized tomography three-dimensional reconstruction before surgery. During the first stage, the soft tissue defect area of scalp (8 cm×7 cm to 18 cm×11 cm) after tumor enlargement resection was repaired with the preformed titanium mesh, and the titanium mesh was covered with latissimus dorsi muscle flap, with area of 10 cm×9 cm to 20 cm×13 cm. The thoracodorsal artery/vein was anastomosed with the superficial temporal artery/vein on one side. The muscle ends in the donor site were sutured together or performed with transfixion, and then the skin on the back were covered back to the donor site. On the 10th day after the first-stage surgery, the second-stage surgery was performed. The thin intermediate thickness skin graft was taken from the anterolateral thigh to cover the latissimus dorsi muscle flap. The duration and intraoperative blood loss of first-stage surgery were recorded. The postoperative muscle flap survival after the first-stage surgery and skin graft survival after the second-stage surgery was observed. The occurrence of complications, head appearance, and recurrence of tumor were followed up. Results: The average first-stage surgery duration of patients was 12.1 h, and the intraoperative blood loss was not more than 1 200 mL. The muscle flaps in the first-stage surgery and the skin grafts in the second-stage surgery all survived well. During the follow-up of 6-18 months, no complications such as exposure of titanium mesh or infection occurred, with good shape in the recipient sites in the vertex, and no recurrence of tumor. Conclusions: Three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation and intermediate thickness skin graft cover is an effective and reliable method for repairing the wound with skull defect after extended resection of squamous cell carcinoma in the vertex. This method can cover the wound effectively as well as promote both recipient and donor sites to obtain good function and appearance.

ABSTRACT

The oligometastatic and oligoprogressive state has been a hot issue in cancer research. Its indolent tumor behavior, representing a novel therapeutic opportunity, has been identified as a clinical subtype in several malignancies. However, the clinical implications of the oligometastatic and oligoprogressive state in esophageal squamous cell carcinoma (ESCC) have not been thoroughly elucidated. There are still controversies regarding the existence of the oligometastatic state in ESCC, if the solitary regional lymph node metastasis should be viewed as oligoprogressive disease after esophagectomy, and the role of surgery and radiotherapy in ESCC oligometastatic disease. Despite many exciting contributions to the literature on these, further exploration is warranted. Thus, fostering the advance of research and scientific knowledge on the biological and prognostic characteristics scrupulously would facilitate personalizing treatment strategy for better outcomes.

ABSTRACT

Objective: Local recurrence is the main cause of treatment failure in patients with oral squamous cell carcinoma (OSCC). This study was proposed to investigate the feasibility of near infrared fluorescence (NIF) via indocyanine green (ICG) for monitoring surgical marginal in operation for OSCC patients. Methods: In 35 patients with OSCC treated surgically in the Department of Oral and Maxillofacial Surgery, Nanjing University School of Medicine, from January 2019 to June 2020, ICG (0.75 mg/kg) was administered intravenously via elbow vein at (12±1) hours before surgery, and NIF was performed intraoperatively on the surgical field and the cut edge of the surgically excised specimen, and fluorescence intensity was measured for OSCC tissue and normal oral mucosa, abnormal fluorescence signals were taken and subjected to rapid cryopathological examination. Correlation between NIF tumor boundary grading and pathological tumor boundary grading was analyzed by Spearman correlation analysis. Results: Clear ICG NIF was obtained for tumor lesions in all 35 patients, with a positive rate of 100%. The fluorescence intensity of OSCC tissue was (412.73±146.56) au, which was higher than that of normal oral mucosa tissue [(279.38±82.56) au, P<0.01]. Abnormal fluorescence signals were detected at the tumor bed and the cut edge of the surgical resection specimen in 4 patients, of which 2 cases were pathologically confirmed as cancer cell residue and 2 cases as inflammatory cell infiltration. The rate of positive detection of cut margins using ICG NIF technique in OSCC was 5.7% (2/35). Twenty of the 35 OSCC patients had grade 1, 11 of grade 2, and 4 of grade 3 tumor borders revealed by NIF of surgical resection specimens, which was positively correlated with pathological tumor border (r=0.809, P<0.001). Conclusions: ICG NIF technique can effectively detect the residual cancer cells at the incision margin, which is of great clinical value in reducing local recurrence of OSCC after surgery due to intraoperative cancer residue.

ABSTRACT

Abstract Introduction Lymph node metastasis is a well-known prognostic factor for laryngeal carcinoma. However, current nodal staging systems provide limited information regarding prognosis. Additional parameters should be considered to improve prognostic capacity. Objectives To assess the prognostic values of metastatic lymph node number, ipsilateral/contralateral harvested lymph nodes, and lymph node ratio in patients undergoing surgical treatment of laryngeal squamous cell carcinoma. Methods Seventy-four patients diagnosed with laryngeal squamous cell carcinoma primarily managed surgically were included in this study. The patients' pathological and survival data were obtained from their medical records. The effects of harvested lymph nodes and lymph node ratio on disease-free survival, disease-specific survival, and overall survival were analyzed. Results Ipsilateral, contralateral, and bilateral evaluations of harvested lymph nodes showed no significant associations with prognosis. Lymph node ratio was significantly associated with overall survival when evaluated bilaterally. Metastatic lymph node number showed more suitable stratification than TNM classification. Conclusions Metastatic lymph node number and bilateral lymph node ratio parameters should be taken into consideration to improve the prognostic capacity of TNM.


Resumo Introdução A metástase linfonodal é um fator prognóstico bem conhecido para o carcinoma de laringe. Entretanto, os sistemas atuais de estadiamento nodal fornecem informações limitadas sobre o prognóstico. Parâmetros adicionais devem ser considerados para melhorar a capacidade prognóstica. Objetivos Avaliar os valores prognósticos do número de linfonodos metastáticos, linfonodos ipsilaterais /contralaterais coletados e relação de linfonodos em pacientes submetidos ao tratamento cirúrgico do carcinoma espinocelular da laringe. Método Foram incluídos neste estudo 75 pacientes com diagnóstico de carcinoma espinocelular da laringe, tratados primariamente por meio de cirurgia. Os dados histopatológicos e de sobrevida dos pacientes foram obtidos de seus prontuários médicos. Foram analisados os efeitos dos linfonodos coletados e da relação de linfonodos na sobrevida livre de doença, sobrevida doença-específica e sobrevida global. Resultados As avaliações ipsilateral, contralateral e bilateral dos linfonodos coletados não mostraram associações significativas com o prognóstico. A relação de linfonodos foi significantemente associada à sobrevida global quando avaliada bilateralmente. O número de linfonodos metastáticos mostrou estratificação mais adequada do que a classificação TNM-N. Conclusões Os parâmetros número de linfonodos metastáticos e relação de linfonodos bilateral devem ser levados em consideração para melhorar a capacidade prognóstica da classificação TNM.

ABSTRACT

Abstract Introduction Regional metastases of cutaneous head and neck squamous cell carcinoma occur in approximately 5 % of cases, being the most important prognostic factor in survival, currently with no distinction between parotid and neck metastasis. Objective The purpose of this study was to evaluate the prognostic features among patients with head and neck cutaneous squamous cell carcinoma exhibiting regional metastasis. Methods A retrospective analysis of patients with cutaneous squamous cell carcinoma who underwent parotidectomy and/or neck dissection from 2011 to 2018 at a single institution tertiary center was performed. Patient demographics, clinical, surgical and pathological information, adjuvant treatments, and outcome at last follow-up were collected. Outcomes included disease recurrence and death due to the disease. Prognostic value of clinic pathological features associated with disease-specific survival was obtained. Results Thirty-eight cases of head and neck cutaneous squamous cell carcinoma with parotid and/or neck metastasis were identified. Overall, 18 (47.3 %) patients showed parotid metastasis alone, 12 (31.5 %) exhibited neck metastasis alone and 8 (21.0 %) had both. A primary tumor in the parotid zone (Hazard Ratio ‒ HR = 5.53; p = 0.02) was associated with improved disease-specific survival. Poorer disease-specific survival was observed in patients with higher primary tumor diameter (HR = 1.54; p = 0.002), higher depth of invasion (HR = 2.89; p = 0.02), invasion beyond the subcutaneous fat (HR = 5.05; p = 0.002), neck metastasis at first presentation (HR = 8.74; p < 0.001), number of positive lymph nodes (HR = 1.25; p = 0.004), and higher TNM stages (HR = 7.13; p = 0.009). Patients presenting with isolated parotid metastasis during all follow-ups had better disease-specific survival than those with neck metastasis or both (HR = 3.12; p = 0.02). Conclusion Head and neck cutaneous squamous cell carcinoma with parotid lymph node metastasis demonstrated better outcomes than cases with neck metastasis.


Resumo Introdução As metástases regionais do carcinoma espinocelular cutâneo de cabeça e pescoço ocorrem em aproximadamente 5% dos casos, sendo esse o fator prognóstico mais importante na sobrevida, atualmente sem distinção entre metástases de parótida e cervicais. Objetivo Avaliar as características prognósticas em pacientes com carcinoma espinocelular cutâneo de cabeça e pescoço com metástase regional. Método Foi feita uma análise retrospectiva de pacientes com carcinoma espinocelular cutâneo submetidos à parotidectomia e/ou esvaziamento cervical entre 2011 e 2018 em um único centro terciário de uma única instituição. Dados demográficos dos pacientes, informações clínicas, cirúrgicas e patológicas, tratamentos adjuvantes e desfechos no último acompanhamento foram coletados. Os desfechos incluíram recorrência e morte devido à doença. O valor prognóstico das características clínico-patológicas associadas à sobrevida específica da doença foi obtido. Resultados Foram identificados 38 casos de carcinoma espinocelular cutâneo de cabeça e pescoço com metástase de parótida e/ou pescoço. No geral, 18 (47,3%) pacientes apresentaram metástase da parótida isolada, 12 (31,5%) apresentaram metástase cervical isolada e 8 (21,0%) apresentaram ambos. Um tumor primário na região da parótida (Hazard ratio [HR] = 5,53; p = 0,02) foi associado a melhor sobrevida específica. Pior sobrevida específica foi observada em pacientes com maior diâmetro do tumor primário (HR = 1,54; p = 0,002), maior profundidade de invasão (HR = 2,89; p = 0,02), invasão além da gordura subcutânea (HR = 5,05; p = 0,002), metástase cervical na primeira apresentação (HR = 8,74; p < 0,001), conforme maior número de linfonodos positivos (HR = 1,25; p = 0,004) e estágios TNM mais elevados (HR = 7,13; p = 0,009). Os pacientes que apresentaram metástase da parótida isolada durante todo o acompanhamento apresentaram melhor sobrevida específica do que aqueles com metástase cervical ou ambos (HR = 3,12; p = 0,02). Conclusão Os casos de carcinoma espinocelular cutâneo de cabeça e pescoço com metástase intraparotídea demonstraram melhores desfechos do que aqueles com metástase cervical.

ABSTRACT

Abstract Mohs micrographic surgery is a specialized form of skin cancer surgery that has the highest cure rates for several cutaneous malignancies. Certain skin cancers can have small extensions or "roots" that may be missed if an excised tumor is serially cross-sectioned in a "bread-loaf" fashion, commonly performed on excision specimens. The method of Mohs micrographic surgery is unique in that the dermatologist (Mohs surgeon) acts as both surgeon and pathologist, from the preoperative considerations until the reconstruction. Since Dr. Mohs's initial work in the 1930s, the practice of Mohs micrographic surgery has become increasingly widespread among the dermatologic surgery community worldwide and is considered the treatment of choice for many common and uncommon cutaneous neoplasms. Mohs micrographic surgery spares the maximal amount of normal tissue and is a safe procedure with very few complications, most of them managed by Mohs surgeons in their offices. Mohs micrographic surgery is the standard of care for high risks basal cell carcinomas and cutaneous squamous cell carcinoma and is commonly and increasingly used for melanoma and other rare tumors with superior cure rates. This review better familiarizes the dermatologists with the technique, explains the difference between Mohs micrographic surgery and wide local excision, and discusses its main indications.

ABSTRACT

Neck dissection for oral squamous-cell carcinoma (OSCC) is a clinically controversial issue and has therefore been the subject of abundant research. However, no one has performed a bibliometric study on this topic to date. The aim of this study was to assess the development of research on neck dissection for OSCC in terms of the historical evolution, current hotspots and future directions, particularly including research trends and frontiers from 2010 to 2019. Literature records related to research on neck dissection for OSCC were retrieved from the Web of Science Core Collection (WoSCC). CiteSpace was used as a tool to perform a bibliometric analysis of this topic. The survey included 2 096 papers. "Otorhinolaryngology" was the most popular research area. The most active institutions and countries were Memorial Sloan Kettering Cancer Center and the USA, respectively. Shah J.P. was the most cited author. Among the six identified "core journals", Head & Neck ranked first. The top three trending keywords were 'invasion', 'upper aerodigestive' and 'negative neck'. 'D'Cruz AK (2015)' was the most cited and the strongest burst reference in the last decade. The study evaluated the effect on survival of elective versus therapeutic neck dissection in patients with lateralized early-stage OSCC. The depth of invasion and the management of N0 OSCC were research frontiers in this field. The present study provides a comprehensive bibliometric analysis of research on neck dissection for OSCC, which will assist investigators in exploring potential research directions.

ABSTRACT

Objective: To investigate the treatment method and effect of surgical resection and free flap repair of recurrent malignant tumors of maxillofacial paranasal sinus and skull base. Methods: The clinical data of 9 patients with recurrent maxillofacial paranasal sinus and skull base malignant tumors who underwent surgical resection and free flap repair in the Department of Otorhinolaryngology Head and Neck Surgery of Shandong Provincial Hospital from August 2009 to May 2019 were analyzed retrospectively, including 5 males and 4 females, aged 32-69 years. There were 4 cases of squamous cell carcinoma, 3 cases of adenoid cystic carcinoma, 1 case of myoepithelial carcinoma and 1 case of malignant fibrous histiocytoma. All patients were repaired with anterolateral femoral flap. The treatment process and postoperative effect were analyzed by descriptive statistics. Results: All patients were followed up from 16 months to 6 years. There were 6 cases of recurrence after operation, including 1 case of local recurrence and 5 cases of skull base and craniocerebral recurrence. The median tumor free survival time of recurrent patients was 35 months. Conclusion: Surgical resection and free flap repair can effectively prolong the life of patients with recurrent maxillofacial paranasal sinus and skull base malignant tumors.

ABSTRACT

Objective: To investigate the characteristics of thyroid invasion and central lymph node metastasis of hypopharyngeal carcinoma, and the impact on survival rate and quality of life. Methods: A retrospective analysis of 124 cases (122 males and 2 females with age range from 36 to 78 years old) with laryngopharyngeal squamous cell carcinoma who were initially treated in the Department of Head and Neck Surgery, Beijing Tongren Hospital Affiliated to Capital Medical University from January 2014 to December 2017 was performed. The clinical data included tumor location, pathological T stage, pathological N stage, invasion of thyroid gland, central lymph node metastasis, surgical procedures and so on. Patients were grouped according to if presence of thyroid invasion and central lymph node metastasis. With follow-up, the survival was analyzed by Kaplan-Meier method, and tumor recurrence and metastasis were evaluated. Results: Of the patients, 12 patients had thyroid involvement and 5 patients had central lymph node metastasis. The incidence of thyroid involvement was 8.16% (8/98) in pyriform sinus, 1/18 in posterior pharyngeal wall and 3/8 in posterior cricoid wall, with statistically significant difference (χ2=15.076,P=0.008). The incidence of central lymph node metastasis was 1.02% (1/98) in pyriform sinus, 3/18 in posterior pharyngeal wall and 1/8 in posterior cricoid wall, also with statistically significant difference (χ2=11.205, P=0.008). There was no statistical correlation between thyroid invasion or central lymph node metastasis and gender, smoking or alcohol exposure history and tumor pathological differentiation (all P>0.05). The 3-year overall survival rate was 80.65% and the 3-year recurrence free rate was 85.48%. Totally 24 patients died in 3 years, including 4 cases in thyroid invasion group and 1 case in central lymph node metastasis group. Local recurrence occurred in 18 patients, including 4 cases in thyroid invasion group and 1 case in central lymph node metastasis group. There was no significant difference in survival between patients with and without thyroid invasion and central lymph node metastasis (all P>0.05). There were significantly difference in 3-year overall survival and relapse-free survival among the groups with different T stages, N stages, pathological stages and tumor pathological differentiation levels (all P<0.05). There were significantly differences in the levels of serum calcium and FT3 between the groups with or without thyroid invasion and central lymph node metastasis (all P<0.05). Conclusion: The incidences of thyroid invasion and central lymph node metastasis of hypopharyngeal carcinoma are rare, and the risk of occurrence is related to the primary site of tumor. Comprehensive evaluation, correct decision-making and accurate treatment could be helpful to cure radically the tumor, to prevent recurrence and to improve the quality of life of patients.
