Recurrent oropharyngeal squamous cell carcinoma causes great morbidity and mortality. This systematic review analyses survival outcomes following salvage surgery for recurrent oropharyngeal squamous cell carcinoma. A comprehensive search of various electronic databases was conducted. Studies included patients with recurrent or residual oropharyngeal squamous cell carcinoma treated with salvage surgery. Primary outcomes were survival rates following salvage surgery. Secondary outcomes included time to recurrence, staging at time of recurrence, post-operative complications, and factors associated with mortality and recurrence. Methodological appraisal and data extraction were conducted as per Joanna Briggs Institute methodology. Eighteen articles were included. The two- and five-year survival rates of the patients were 52 per cent and 30 per cent respectively. Improvements in treatment modalities for recurrent oropharyngeal squamous cell carcinoma were associated with improvements in two-year overall survival rates, with minimal change to five-year overall survival rates. Various factors were identified as being associated with long-term overall survival, thus assisting clinicians in patient counselling and selection for salvage surgery.

Local recurrences after curative treatment have a potential for cure with salvage surgery or with re-irradiation. We reviewed the PubMed for articles published in English with key words squamous cell carcinoma, recurrent, re-irradiation, prognostic factors to find relevant articles describing prognostic factors, re-irradiation, and outcome for recurrent head and neck squamous cell carcinoma. Various factors including age, performance status, time for recurrence, previous radiation dose volume and site of recurrence, previous use of chemotherapy are all prognostic factors in recurrent head and neck squamous cell carcinoma. Surgery is feasible in very select subgroup of patients and must be done when feasible. Re-irradiation with the aid of modern sophisticated technology is safe and confers durable and clinically meaningful survival benefit. Re-irradiation in head and neck recurrent squamous cell carcinoma may provide an expected median survival of 10-12months. Chemotherapy may be added along with radiation in the recurrent setting. Treatment approaches may have to be personalized. Re surgery must be done in all patients in whom it is feasible. In patients in whom surgery is not feasible, re-irradiation must be evaluated as a therapeutic option especially in patients with limited volume recurrence.

2018-04-01

Although diffusion-weighted imaging combined with morphologic MRI (DWIMRI) is used to detect posttreatment recurrent and second primary head and neck squamous cell carcinoma, the diagnostic criteria used so far have not been clarified. We hypothesized that precise MRI criteria based on signal intensity patterns on T2 and contrast-enhanced T1 complement DWI and therefore improve the diagnostic performance of DWIMRI. We analyzed 1.5T MRI examinations of 100 consecutive patients treated with radiation therapy with or without additional surgery for head and neck squamous cell carcinoma. MRI examinations included morphologic sequences and DWI ( b =0 and b =1000 s/mm 2 ). Histology and follow-up served as the standard of reference. Two experienced readers, blinded to clinical/histologic/follow-up data, evaluated images according to clearly defined criteria for the diagnosis of recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment, post-radiation therapy inflammatory edema, and late fibrosis. DWI analysis included qualitative (visual) and quantitative evaluation with an ADC threshold. Recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment was present in 36 patients, whereas 64 patients had post-radiation therapy lesions only. The Cohen κ for differentiating tumor from post-radiation therapy lesions with MRI and qualitative DWIMRI was 0.822 and 0.881, respectively. Mean ADCmean in recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment (1.097 ± 0.295 × 10 -3 mm 2 /s) was significantly lower ( P < .05) than in post-radiation therapy inflammatory edema (1.754 ± 0.343 × 10 -3 mm 2 /s); however, it was similar to that in late fibrosis (0.987 ± 0.264 × 10 -3 mm 2 /s, P > .05). Although ADCs were similar in tumors and late fibrosis, morphologic MRI criteria facilitated distinction between the 2 conditions. The sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios (95% CI) of DWIMRI with ADCmean < 1.22 × 10 -3 mm 2 /s and precise MRI criteria were 92.1% (83.5-100.0), 95.4% (90.3-100.0), 92.1% (83.5-100.0), 95.4% (90.2-100.0), 19.9 (6.58-60.5), and 0.08 (0.03-0.24), respectively, indicating a good diagnostic performance to rule in and rule out disease. Adding precise morphologic MRI criteria to quantitative DWI enables reproducible and accurate detection of recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment. © 2018 by American Journal of Neuroradiology.

The incidence of oropharyngeal squamous cell carcinoma in the Western world is increasing, with the human papillomavirus epidemic implicated in this observed trend. The optimal treatment modality is yet undetermined regarding oncological outcomes. This study comprised 98 patients with oropharyngeal squamous cell carcinoma, treated with either primary transoral surgery with adjuvant therapy or primary chemoradiotherapy with curative intent, between 2008 and 2012. Clinicopathological characteristics including tumour-node-metastasis stage, human papillomavirus status, treatment modality, recurrence and overall survival were collated. Five per cent of primary surgical patients had locoregional recurrences compared with 25 per cent of primary chemoradiotherapy patients. A lower rate of locoregional recurrence was observed in the human papillomavirus positive group. This paper reports higher rates of overall survival and local control for oropharyngeal squamous cell carcinoma treated with primary surgery compared with primary chemoradiotherapy. This reflects overall lower tumour stage and higher human papillomavirus status in this group.

Spindle cell carcinoma (SpCC), which predominantly arises in the oral, pharyngeal and laryngeal mucosal tissues, is composed of a mixture of squamous and sarcomatoid components. The present study describes the case of a 62-year-old woman with SpCC recurrence 4 years after an initial surgery to remove a well-differentiated primary squamous cell carcinoma (SCC) of the tongue. The recurrent tumor was spherical and located deep within the tongue tissue, which differs from the typical manifestation of ulcerated masses of the mucosa. The majority of cases of recurrence involving SpCC are associated with radiotherapeutic treatment of the primary malignancy; however, the patient in the present study had not received postoperative radiotherapy for SCC. Furthermore, the recurrent tumor in the present case exhibited marked anaplasia and sarcomatoid features, and the absence of SCC elements upon biopsy rendered histological diagnosis difficult. In summary, the present findings suggest that immunohistochemical examination and identification of SCC components are essential for ensuring the accuracy of the histological diagnosis of recurrent SpCC following a primary epithelial malignancy.

Furthermore, the recurrent tumor in the present case exhibited marked anaplasia and sarcomatoid features, and the absence of SCC elements upon biopsy rendered histological diagnosis difficult. In summary, the present findings suggest that immunohistochemical examination and identification of SCC components are essential for ensuring the accuracy of the histological diagnosis of recurrent SpCC following a primary epithelial malignancy.

Primary candidiasis and squamous cell carcinoma of the larynx: report of a case.

PubMed

Lee, Dong Hoon; Cho, Hyong Ho

Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

Extra-abdominal desmoid tumor, also known as aggressive fibromatosis, has aggressive behavior with local infiltration and tendency for recurrence. Though head and neck is reported to be one of the most common sites, a desmoid tumor in the larynx is extremely rare. A 67-year-old male visited our hospital with prolonged hoarseness and received laryngo-microsurgery with the diagnosis of laryngeal polyp. After the operation, he eventually developed a laryngeal squamous cell carcinoma with papilloma, confirmed by second laryngo-microsurgery and received radiation therapy. After the third laryngo-microsurgery to remove residual papilloma, white irregular mass appeared on the right vocal cord and grew rapidly beneath the glottis, causing dyspnea. After 2 additional laryngo-microsurgeries, he was diagnosed having the dermoid tumor co-existing with recurrent squamous cell carcinoma. He underwent near-total laryngectomy and is currently alive without disease, speaking using a vocal shunt. Only five cases of the desmoid tumors arising in the adult larynx have been reported in the English literature. In this case, repeated surgery and radiation were suspected as the causes. Also, the present report is the first to describe desmoid tumor co-existing with recurrent squamous cell carcinoma in the larynx. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Xeroderma pigmentosum, an autosomal recessive disease that occurs with a frequency of 1:250,000, is caused by a genetic defect in nucleotide excision repair enzymes. Mutation of these enzymes leads to the development of multiple basal cell and squamous cell carcinomas. We present a case of xeroderma pigmentosum in a patient with cervical and intraparotid metastatic disease from recurrent cutaneous squamous cell carcinomas of the face and scalp, treated with neck dissection and re-irradiation. With the illustrative case report, we include a literature review of diagnosis, prognostic factors, and treatment, with emphasis on surgical and radiation treatment of cervical metastatic disease from recurrent skin carcinomas. A xeroderma pigmentosum patient presented to our clinic with a 2-cm right submental and 1-cm right infra-auricular mass after resection of multiple squamous cell carcinomas of the scalp and face, and external-beam radiation therapy to the right face and neck. Fine-needle aspiration biopsy of the submental mass revealed poorly differentiated squamous cell carcinoma. The patient was brought to the operating room for a right modified radical neck dissection and excision of the right submental and intraparotid mass. Surgical pathology revealed 3 level ia and supraclavicular lymph nodes that were positive for metastatic squamous cell carcinoma. Re-irradiation to the entire right hemi-neck and left submandibular nodal region was performed using opposed oblique portals for the upper neck and a low anterior en face hemi-neck portal. The left parotid region was also included in the re-irradiation volume. Treatment was completed without delayed complications or recurrences to date. To our knowledge, this is the first case report in the literature of a patient with xeroderma pigmentosum who subsequently developed metastatic disease from recurrent cutaneous squamous cell carcinoma. Because of the rarity of xeroderma pigmentosum, this case report is also the first to describe re-irradiation to treat cervical and intraparotid metastatic disease in a xeroderma pigmentosum patient.

Adjunctive radiotherapy with strontium-90 in the treatment of conjunctival squamous cell carcinoma.

PubMed

Kearsley, J H; Fitchew, R S; Taylor, R G

1988-03-01

Squamous cell carcinoma of the ocular conjunctiva is a relatively rare malignancy which is attended by a high rate of local recurrence following simple surgical excision. To date, the management of conjunctival squamous cell cancer has been controversial. From 1950 to 1985, 146 consecutive patients with superficial conjunctival squamous cell cancer were treated at the Queensland Radium Institute. All patients were treated by simple surgical excision of the visible conjunctival lesion followed by adjunctive radiotherapy. Of 140 patients with histologically confirmed squamous cell cancer, 123 were treated with a strontium-90 source, 10 with a radon "ring," and 7 with superficial X ray therapy. Standard policy since 1960 has been to deliver an incident dose of 30 Gy in a single fraction within the first 48 post-operative hours to the surgical bed using a strontium-90 source on a stand-off eye applicator. This report will largely focus on the 123 patients who were treated with a strontium-90 source, of whom 107 received 30 Gy, 14 received 40 Gy (pre 1960) and one patient each received 20 and 25 Gy incident dose. Of 131 evaluable patients, there were only 3 who developed local recurrence. All 3 local recurrences developed in elderly men who had presented with extensive superficial primary tumors. Two of the three recurrences occurred in the two patients who were treated with doses less than 30 Gy. Both early and late radiation-induced complications following ablative surgery and treatment with strontium-90 were very uncommon. Three patients developed unsightly conjunctival telangiectasia, 2 patients developed a persistent scleral ulcer and 2 patients developed clinically significant cataracts. This negligible degree of treatment-related side effects contrasts with the experience of 10 patients who had previously been treated with a radon ring, 8 of whom developed serious complications, although none developed local recurrence. On the basis of our excellent local control rates with minimal morbidity we would continue to advocate the use of simple surgical excision followed by 30 Gy beta radiation from a strontium-90 source as the definitive treatment for superficial conjunctival squamous cell cancer.

Background: Although advance techniques were available for diagnosis and prognosis of oral cancer, histopathology was used as major method in clinical routine. Of all oral subsites, buccal mucosa squamous cell carcinoma is aggressive in nature with poor survival. Therefore, the aim of the present study was to evaluate the relation of tumor histopathological grade with disease recurrence of buccal squamous cell mucosa carcinoma. Materials and Methods: A retrospective study was carried out in regional cancer research institute, Tamil Nadu. Demographic, histopathological and participant's follow-up details were collected from medical records. Results: Of 198 participants, high frequently encountered with well-differentiated squamous cell carcinoma (n = 98, 49.5%). The clinical characteristics of lymphovascular invasion (P = 0.031), perineural invasion (P = 0.019), tumor stage (P = 0.004), tumor depth (P = 0.048), lymph node (P = 0.02) and metastasis (P = 0.043) had significant association with histopathological grade. In addition, the treatment strategies (P = 0.014) also showed significance at P < 0.05. Further, multivariate revealed cell differentiation (P = 0.048), tumor size (P = 0.037) and depth (P = 0.021) as independent hazard risk of the development of disease using recurrence-free survival of participants at P < 0.05. Of 198 participants, 24 (12.1%) recurrences reported during 34-month follow-up period and the overall estimated recurrence-free survival was 52%. The high frequency of recurrence, 12 (50%), was identified with moderately differentiated tumor cells. However, poorly differentiated tumor showed significantly lower survival (28%) than moderate (54%) and well differentiated (81%) by Kaplan–Meier analysis using log-rank test (P = 0.004, P < 0.05). Conclusions: The present study concludes high frequency of recurrence observed in moderately differentiated and also revealed lower survival in poorly differentiated tumor. Hence, further treatment plans should focus on moderate and poorly differentiated tumors to improve survival outcome. PMID:29391735

Is there a role of whole-body bone scan in patients with esophageal squamous cell carcinoma

PubMed Central

2012-01-01

Background Correct detection of bone metastases in patients with esophageal squamous cell carcinoma is pivotal for prognosis and selection of an appropriate treatment regimen. Whole-body bone scan for staging is not routinely recommended in patients with esophageal squamous cell carcinoma. The aim of this study was to investigate the role of bone scan in detecting bone metastases in patients with esophageal squamous cell carcinoma. Methods We retrospectively evaluated the radiographic and scintigraphic images of 360 esophageal squamous cell carcinoma patients between 1999 and 2008. Of these 360 patients, 288 patients received bone scan during pretreatment staging, and sensitivity, specificity, positive predictive value, and negative predictive value of bone scan were determined. Of these 360 patients, surgery was performed in 161 patients including 119 patients with preoperative bone scan and 42 patients without preoperative bone scan. Among these 161 patients receiving surgery, 133 patients had stages II + III disease, including 99 patients with preoperative bone scan and 34 patients without preoperative bone scan. Bone recurrence-free survival and overall survival were compared in all 161 patients and 133 stages II + III patients, respectively. Results The diagnostic performance for bone metastasis was as follows: sensitivity, 80%; specificity, 90.1%; positive predictive value, 43.5%; and negative predictive value, 97.9%. In all 161 patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.009, univariately). In multivariate comparison, absence of preoperative bone scan (P = 0.012, odds ratio: 5.053) represented the independent adverse prognosticator for bone recurrence-free survival. In 133 stages II + III patients receiving surgery, absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival (P = 0.003, univariately) and overall survival (P = 0.037, univariately). In multivariate comparison, absence of preoperative bone scan was independently associated with inferior bone recurrence-free survival (P = 0.009, odds ratio: 5.832) and overall survival (P = 0.029, odds ratio: 1.603). Conclusions Absence of preoperative bone scan was significantly associated with inferior bone recurrence-free survival, suggesting that whole-body bone scan should be performed before esophagectomy in patients with esophageal squamous cell carcinoma, especially in patients with advanced stages.

Twenty-six patients with advanced or recurrent cancer of the vagina no longer amenable to control with surgery and/or radiotherapy were entered into a phase II study of cisplatin 50 mg/m2 intravenously every 3 weeks. Two were deemed ineligible because of a primary site of origin other than vagina. Two were deemed inevaluable, one because of the lack of measurable disease and the other because she never received drug. The remaining 22 included a variety of histologies (16 squamous cell carcinomas, 2 adenosquamous carcinomas, 1 clear cell carcinoma, 1 leiomyosarcoma, and 2 carcinomas not otherwise specified). One complete responder was observed among the 16 patients with squamous cell carcinoma. Adverse effects were tolerable and were essentially those reported in other series. These results suggest that cisplatin has insignificant activity in advanced or recurrent squamous cell carcinoma of the vagina at least at the dose and schedule tested. No comment can be made regarding the activity of cisplatin in other histologies.

Patients with esophageal squamous cell carcinoma have poor survival and high recurrence rate, thus an effective prognostic biomarker is needed. Endothelin-converting enzyme-1 is responsible for biosynthesis of endothelin-1, which promotes growth and invasion of human cancers. The role of endothelin-converting enzyme-1 in esophageal squamous cell carcinoma is still unknown. Therefore, this study investigated the significance of endothelin-converting enzyme-1 expression in esophageal squamous cell carcinoma clinically. We enrolled patients with esophageal squamous cell carcinoma who provided pretreated tumor tissues. Tumor endothelin-converting enzyme-1 expression was evaluated by immunohistochemistry and was defined as either low or high expression. Then we evaluated whether tumor endothelin-converting enzyme-1 expression had any association with clinicopathological findings or predicted survival of patients with esophageal squamous cell carcinoma. Overall, 54 of 99 patients with esophageal squamous cell carcinoma had high tumor endothelin-converting enzyme-1 expression, which was significantly associated with lymph node metastasis ( p = 0.04). In addition, tumor endothelin-converting enzyme-1 expression independently predicted survival of patients with esophageal squamous cell carcinoma, and the 5-year survival was poorer in patients with high tumor endothelin-converting enzyme-1 expression ( p = 0.016). Among patients with locally advanced and potentially resectable esophageal squamous cell carcinoma (stage II and III), 5-year survival was poorer with high tumor endothelin-converting enzyme-1 expression ( p = 0.003). High tumor endothelin-converting enzyme-1 expression also significantly predicted poorer survival of patients in this population. In patients with esophageal squamous cell carcinoma, high tumor endothelin-converting enzyme-1 expression might indicate high tumor invasive property. Therefore, tumor endothelin-converting enzyme-1 expression could be a good biomarker to identify patients with worse survival and higher risks of recurrence, who might benefit from the treatment by endothelin-converting enzyme-1 inhibitor.

Advanced stage squamous cell carcinoma of the head and neck carries an overall poor prognosis, and survivorship gains have remained relatively stagnant compared to other malignancies due to its complex tumor biology and lack of proven effective targeting agents. We present a case of an exceptional responder to molecular-targeted therapy for metastatic oropharyngeal squamous cell carcinoma using a chemotherapeutic agent FDA approved for breast cancer and targeting the HER2/Neu receptor in order to discuss the larger clinical implications. The National Cancer Institute (NCI) has recently instituted the Exceptional Responders Initiative in order to identify such patients with unexpected outcomes in order to expedite the development of additional targeted therapies. This case illustrates the opportunity for cure using targeted oncogene identification in a scenario of recurrent squamous cell carcinoma with lung metastasis typically considered fatal. Molecular tumor analysis is an infrequently utilized tool in head and neck squamous cell carcinoma; however, as understanding of biologic mechanisms improves, additional molecular targets will become available and expand treatment opportunities such as HER2/Neu targeting. The Exceptional Responders Initiative is a unique strategy with potential to expedite progress.

The squamous cell carcinomas represent about 90 % of all head and neck cancers, ranking the sixth most common human cancer. Approximately 450,000 of new cases of head and neck squamous cell carcinoma (HNSCC) are diagnosed every year. Unfortunately, because of diagnosis at the advanced stages and early metastasis to the lymph nodes, the HNSCC is associated with very high death rate. Identification of signature biomarkers and molecularly targeted therapies could provide more effective and specific cancer treatment, prevent recurrence, and increase survival rate. We used paired tumor and adjacent normal tissue samples to screen with RT² Profiler™ PCR Array Human Cancer PathwayFinderTM. Total of 20 up-regulated genes and two down-regulated genes were screened out. Out of 22 genes, 12 genes were subsequently validated to be significantly altered in the HNSCC; the samples were from all 41 patients. Five year survival and recurrence selected genes that could represent the biomarkers of survival and recurrence of the disease. We believe that comprehensive understanding of the unique genetic characteristics of HNSCC could provide novel diagnostic biomarkers and meet the requirement for molecular-targeted therapy for the HNSCC.

Purpose: To assess the toxicity profile of erlotinib therapy combined with postoperative adjuvant radiation therapy in patients with advanced cutaneous squamous cell carcinoma. Methods and Materials: This was a single-arm, prospective, phase 1 open-label study of erlotinib with radiation therapy to treat 15 patients with advanced cutaneous head-and-neck squamous cell carcinoma. Toxicity data were summarized, and survival was analyzed with the Kaplan-Meier method. Results: The majority of patients were male (87%) and presented with T4 disease (93%). The most common toxicity attributed to erlotinib was a grade 2-3 dermatologic reaction occurring in 100% of the patients, followed by mucositis (87%).more » Diarrhea occurred in 20% of the patients. The 2-year recurrence rate was 26.7%, and mean time to cancer recurrence was 10.5 months. Two-year overall survival was 65%, and disease-free survival was 60%. Conclusions: Erlotinib and radiation therapy had an acceptable toxicity profile in patients with advanced cutaneous squamous cell carcinoma. The disease-free survival in this cohort was comparable to that in historical controls.« less

Three-Dimensional Image Fusion of 18F-Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography and Contrast-Enhanced Computed Tomography for Computer-Assisted Planning of Maxillectomy of Recurrent Maxillary Squamous Cell Carcinoma and Defect Reconstruction.

The purpose of this study was to describe new technology assisted by 3-dimensional (3D) image fusion of 18 F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) and contrast-enhanced CT (CECT) for computer planning of a maxillectomy of recurrent maxillary squamous cell carcinoma and defect reconstruction. Treatment of recurrent maxillary squamous cell carcinoma usually includes tumor resection and free flap reconstruction. FDG-PET/CT provided images of regions of abnormal glucose uptake and thus showed metabolic tumor volume to guide tumor resection. CECT data were used to create 3D reconstructed images of vessels to show the vascular diameters and locations, so that the most suitable vein and artery could be selected during anastomosis of the free flap. The data from preoperative maxillofacial CECT scans and FDG-PET/CT imaging were imported into the navigation system (iPlan 3.0; Brainlab, Feldkirchen, Germany). Three-dimensional image fusion between FDG-PET/CT and CECT was accomplished using Brainlab software according to the position of the 2 skulls simulated in the CECT image and PET/CT image, respectively. After verification of the image fusion accuracy, the 3D reconstruction images of the metabolic tumor, vessels, and other critical structures could be visualized within the same coordinate system. These sagittal, coronal, axial, and 3D reconstruction images were used to determine the virtual osteotomy sites and reconstruction plan, which was provided to the surgeon and used for surgical navigation. The average shift of the 3D image fusion between FDG-PET/CT and CECT was less than 1 mm. This technique, by clearly showing the metabolic tumor volume and the most suitable vessels for anastomosis, facilitated resection and reconstruction of recurrent maxillary squamous cell carcinoma. We used 3D image fusion of FDG-PET/CT and CECT to successfully accomplish resection and reconstruction of recurrent maxillary squamous cell carcinoma. This method has the potential to improve the clinical outcomes of these challenging procedures. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

Cancer stem cells (CSCs) play a major role in local recurrence and metastatic spread in head and neck squamous cell carcinomas (HNSCC). Evidence suggests that cancer stem cells are resistant to conventional therapy. So the emerging concepts of the role of cancer stem cells in the pathobiology of HNSCC should be understood carefully to be able to create new paradigms in treatment plans.

The aim of this study was to investigate the expressions of cell cycle regulatory proteins such as p53, p16, p21, and Rb in squamous cell carcinoma of the oropharynx and their relation to histological differentiation, staging of disease, and prognosis. Paraffin blocks from 21 primary tumors were obtained from archives of the Department of Pathology, Paulista Medical School, Federal University of Sao Paulo, UNIFESP/EPM. Immunohistochemistry was used to detect the expression of p53, p16, p21, and Rb by means of tissue microarrays. Expression of p53, p21, p16 and Rb was not correlated with the stage of disease, histopathological grading or recurrence in squamous cell carcinoma of the oropharynx. Taken together, our results suggest that p53, p16, p21 and Rb are not reliable biomarkers for prognosis of the tumor severity or recurrence in squamous cell carcinoma of the oropharynx as depicted by tissue microarrays and immunohistochemistry.

Squamous cell carcinoma (SCC) of the scrotum is an uncommon neoplasm. It has been described in many different occupations and is associated with a myriad of carcinogens, yet the etiology still remains a mystery. This is the first report of its occurrence in a radiation technologist. Additionally, the use of sentinel lymph node biopsy in SCC has been advocated as a safe method of limiting the morbidity associated with bilateral ilioinguinal dissections. This is the first report of its use in recurrent metastatic SCC of the scrotum.

ABSTRACT Objective To review recent literature on human papillomavirus‐related (HPV‐positive) oropharyngeal squamous cell carcinoma (OPC) and focus on implications of recurrent and metastatic disease. Methods Primary articles from 1990 to 2016 indexed in MEDLINE (1) pertaining to the epidemiology of HPV‐positive OPC and (2) providing clinical insight into recurrent and metastatic OPC. Results The incidence of HPV‐positive OPC is increasing globally. HPV‐positive OPC is a subtype with distinct molecular and clinical features including enhanced treatment response and improved overall survival. While disease recurrence is less common in patients with HPV‐positive OPC, up to 36% of patients experience treatment failure within eight years. Recurrent and metastatic OPC has historically signified poor prognosis, however recent data are challenging this dogma. Here, we discuss recurrent and metastatic OPC in the context of HPV tumor status. Conclusion HPV‐positive OPC exhibits distinct genetic, cellular, epidemiological, and clinical features from HPV‐negative OPC. HPV tumor status is emerging as a marker indicative of improved prognosis after disease progression in both locoregionally recurrent and distant metastatic OPC. Level of Evidence N/A. PMID:28894817

The aim of this study was to determine the methylation status of the genes encoding the vascular endothelial growth factor receptors and to evaluate the usefulness of VEGFR methylation as a prognostic indicator in head and neck squamous cell carcinoma. VEGFR messenger RNA expression and promoter methylation were examined in a panel of cell lines via quantitative reverse transcription and methylation-specific polymerase chain reaction, respectively. Promoter methylation was compared with clinical characteristics in 128 head and neck squamous cell carcinoma samples. The normalized methylation values for the VEGFR1, VEGFR2 and VEGFR3 promoters tended to be higher in the tumour cell lines than in normal tonsil samples, whereas amounts of VEGFR1, VEGFR2 and VEGFR3 messenger RNA were significantly higher. Methylation of the VEGFR1 promoter (p = 0.003; 66/128 head and neck squamous cell carcinoma samples, 52%) and VEGFR3 promoter (p = 0.043; 53/128 head and neck squamous cell carcinoma samples, 41%) significantly correlated with recurrence, whereas methylation of the VEGFR2 promoter significantly correlated with lymph node metastasis (p = 0.046; 47/128 head and neck squamous cell carcinoma samples, 37%). Concurrent methylation of the VEGFR1 and VEGFR3 promoters significantly correlated with reduced disease-free survival (log-rank test, p = 0.009). In a multivariate logistic regression analysis, methylation of the VEGFR1, VEGFR3 and both the VEGFR1 and VEGFR3 promoters independently predicted recurrence (odds ratios and 95% confidence intervals: 3.19, 1.51-6.75 (p = 0.002); 2.24, 1.06-4.76 (p = 0.035); and 2.56, 1.09-6.05 (p = 0.032), respectively). Methylation of the VEGFR promoters predicts poor prognosis in head and neck squamous cell carcinoma patients.

This study evaluates the oncological outcome of patients with recurrent oropharyngeal squamous cell carcinoma (OPSCC) after primary radiation therapy +/- chemotherapy, primary surgical therapy, and surgical therapy followed by radiation therapy +/- chemotherapy. A total of 156 patients (36%) of a cohort of 427 treated for OPSCC between 1990 and 2006 developed recurrent disease. Fifty-one patients (12%) qualified for salvage treatment. Study endpoints were 5-year overall survival (OS) and disease-specific survival (DSS). The 5-year OS and DSS rates after salvage treatment were 29% and 40%; after initial primary radiation therapy, 25% and 40%; after initial surgery followed by radiation therapy, 40% and 40%; and after initial surgery alone, 20% and 40%. Patients with an advanced OPSCC have a considerable risk for recurrence. Despite poor ultimate outcome, salvage treatment should be attempted in patients with resectable disease, good performance status, and absence of distant metastases. 2009 Wiley Periodicals, Inc.

Radiation changes are observed in all postirradiated smears of squamous cell carcinoma of the cervix from 56 females, although to a variable degree. After 1 year the changes subside gradually. A high cornification index is a good guide for recurrence. The significance of dysplastic cells as premonition for recurrence is debatable. The presence of malignant cells at any stage was considered of grave significance, and indicates poor radiation response or recurrence.

Expression of E-cadherin and β-catenin in basaloid and conventional squamous cell carcinoma of the oral cavity: are potential prognostic markers?

PubMed Central

2014-01-01

Background Basaloid squamous cell carcinoma presents with a preference for the head and neck region, and shows a distinct aggressive behavior, with frequent local recurrences, regional and distant metastasis. The alterations in the cadherin-catenin complex are fundamental requirements for the metastasis process, and this is the first study to evaluate the immunostaining of E-cadherin and β-catenin in oral basaloid squamous cell carcinoma. Methods Seventeen cases of this tumor located exclusively in the mouth were compared to 26 cases of poorly differentiated squamous cell carcinoma and 28 cases of well to moderately differentiated squamous cell carcinoma matched by stage and tumor site. The immunostaining of E-cadherin and β-catenin were evaluated in the three groups and compared to their clinicopathological features and prognosis. Results For groups poorly differentiated squamous cell carcinoma and basaloid squamous cell carcinoma, reduction or absence of E-cadherin staining was observed in more than 80.0% of carcinomas, and it was statistically significant compared to well to moderately differentiated squamous cell carcinoma (p = .019). A strong expression of β-catenin was observed in 26.9% and 20.8% of well to moderately differentiated squamous cell carcinoma and poorly differentiated squamous cell carcinoma, respectively, and in 41.2% of basaloid squamous cell carcinoma. The 5-year and 10-year overall and disease-free survival rates demonstrated no significant differences among all three groups. Conclusions The clinical and biological behavior of three groups of the oral cavity tumors evaluated are similar. E-cadherin and β-catenin immunostaining showed no prognostic value for basaloid and conventional squamous cell carcinomas. PMID:24893577

To report the results of patients undergoing combined excision, cryotherapy, and intraoperative mitomycin-C (EXCRIM) for primary ocular surface squamous neoplasia (OSSN) METHODS: A retrospective review of a non-comparative interventional case series. Histopathologically confirmed primary localized (less than four clock hours) OSSN treated with EXCRIM using adjuvant 0.02 % mitomycin-C (MMC) were included in the study. The main outcome measures were recurrence and complications related to MMC. The study enrolled 28 eyes of 28 patients with OSSN with a median age of 64.5 (range 43 to 84) years. The mean tumor size was 6.9 × 4.35 mm. There was corneal involvement in 23 of 28 (82 %). Seven patients (21 %) had delayed epithelial healing. Two of eight patients (25 %) with squamous cell carcinoma (SCC) had positive lateral margins. There were no recurrences over a mean follow-up of 49 months (range 24 to 96). The excision of OSSN combined with cryotherapy and intraoperative MMC is effective with a low recurrence rate. Long-term follow-up yielded favorable results.

The histologic appearance, locoregional recurrence, and rate/site of metastases of spontaneous feline oral squamous cell carcinoma are similar to head and neck cancer in humans. A feasibility study of intratumoral Etanidazole, a hypoxic cell sensitizer, and radiation therapy were instituted in this model. Eleven cats with feline squamous cell carcinoma were treated with intratumoral Etanidazole and radiation therapy. Total Etanidazole doses were 1.5-24.0 gms/m2 (0.5-6.9 gms). The tumor partial response rate was 100% (11/11); the median volume regression was 70%. All cats have died as a result of tumor recurrence or tumor-related complications. Median survival was 116 days. Ten catsmore » have been autopsied. Non-necrotic and necrotic tumor cells were identified at the treatment site in all cats. Pharmacokinetic studies were performed in six cats. Following intravenous infusion, the plasma elimination of the Etanidazole was biexponential. The systemic availability following intratumoral administration was 61.2 +/- 21.1%. Peak plasma Etanidazole levels were observed 14 minutes following intratumoral injection, after which elimination was biexponential. Thirty minutes following intratumoral Etanidazole administration, tumor Etanidazole levels were 62.8% of plasma levels. Feline squamous cell carcinoma appears to be a useful model of human head and neck cancer. Cats tolerate substantial doses of intratumoral and intravenous Etanidazole. Etanidazole and radiation therapy cause rapid regression, but not cure, of feline squamous cell carcinoma. There is a similarity between the intravenous kinetics of Etanidazole in humans and cats. Further studies in this model are planned.« less

Cutaneous squamous cell carcinoma of the head and neck is an epidemic that reaches all parts of the world. Making the diagnosis relies on the acumen of the clinician and pathologist. Various pathologic subtypes exist and differ in histology and prognosis. High-risk tumors need aggressive treatment and vigilant surveillance to monitor for recurrence. Large tumors, deep tissue invasion, perineural involvement, recurrence, location in high-risk areas, and immunosuppression are implicated in worsening prognosis. Surgery is the mainstay of treatment with adjuvant radiation therapy as needed for aggressive tumors; however, other modalities are potentially useful for low-risk lesions. The use of Mohs surgery has become increasingly useful and has shown high success rates. Involvement of parotid and neck lymph nodes significantly affects outcomes and the physician should be comfortable with management of this complex disease. This paper examines the diagnosis, pathology, clinical course, and treatment options for cutaneous squamous cell carcinoma of the head and neck. PMID:21461387

Pregnancy following vulvar squamous cell carcinoma: a report of two cases

PubMed Central

Tidy, John A

2009-01-01

Pregnancy following squamous cell carcinoma of the vulvar is rare. Its rarity is reflected by a paucity of cases reported in the literature. We report two cases of pregnancy following diagnosis and treatment for vulvar squamous cell carcinoma, and review eleven prior reported cases. In successfully treated vulvar cancer subsequent pregnancy is not shown to increase the risk of disease recurrence, and there appears to be no deleterious effects during the antenatal period. It is possible, when considering prior reports, that prior vulvectomy may increase the likelihood of delivery by caesarean section, though modifications in the surgical management of vulvar carcinoma may have decreased this risk.

Preoperative hyperfibrinogenemia is associated with inflammatory mediators and a poor prognosis in several types of cancer. However, there is no published information on the monitoring of patients with preoperative hyperfibrinogenemia after surgery. The aim of the study reported here was to assess the clinicopathological and prognostic significance of plasma fibrinogen levels in patients with esophageal squamous cell carcinoma before and after surgical treatment. Plasma fibrinogen levels were analyzed before surgical treatment (endoscopic submucosal dissection and surgery) in 82 patients with esophageal squamous cell carcinoma. The clinicopathological significance of plasma fibrinogen levels and the relationship of plasma fibrinogen levels with several biomarkers were evaluated. The cutoff value for hyperfibrinogenemia was 321 mg/dl. Univariate and multivariate analysis using the Cox proportional hazards model were performed to evaluate the prognostic significance of plasma fibrinogen levels. The changing patterns of plasma fibrinogen were monitored after surgical treatment to evaluate prognostic impact. Hyperfibrinogenemia was significantly associated with advanced pathological stage of cancer and high C-reactive protein levels. Plasma fibrinogen levels significantly decreased after surgical treatment in recurrence-free patients but did not decrease in patients with recurrence. The multivariate analysis indicated that preoperative hyperfibrinogenemia was an independent prognostic factor for poor survival (hazard ratio 1.005, 95% confidence interval 1.000-1.010; P = 0.039). Preoperative hyperfibrinogenemia was associated with inflammatory mediators, tumor progression, and poor survival in patients with esophageal squamous cell carcinoma. The absence of a decrease in plasma fibrinogen levels after surgical treatment may indicate the possibility of tumor recurrence.

Seventy-five cases of primary squamous cell carcinoma of the vagina treated at the University of Pennsylvania are reviewed with long-term follow-up presented. These comprised 2.5% of all female genital malignancies treated during 1958 to 1980 inclusive. Patients treated during that time with non-squamous cell cancers have been excluded. Patients are analyzed with regard to stage, therapy, complications, and survival. Sixty-five percent of patients were stage I or II. Five-year survival for the entire group was 45%. Patients treated with radical surgery other than exenteration did well, with 7 of 8 surviving 5 years. Serious treatment complications were mostly related tomore » radiation therapy and primarily involved the bowel and bladder. Three patients died of complications. Recurrence carried a grave prognosis as 30 of 33 patients with recurrence died of disease. Most recurrences were diagnosed within the first year following treatment. Patients with advanced disease were more likely to have distant recurrences. Although radiation therapy is generally the treatment of choice, radical surgery can yield excellent results when used in carefully selected patients. With meticulous attention to radiation dosage and technique it is hoped that treatment morbidity can be reduced. Optimal treatment of advanced disease may require some form of adjuvant systemic therapy.« less

The aim of this study was to assess the curative and cosmetic efficacy of treatment for facial skin cancer using neodymium laser irradiation. Due to the complex anatomy of the area, therapy for facial skin cancer is difficult. Laser irradiation was used for the treatment of 3461 patients with 3624 facial skin cancer lesions of stages T(1-2)N(0)M(0:) 3346 basal cell skin cancers, 188 limited basal cell skin cancer recurrences, and 90 squamous cell skin cancers. Pulsed neodymium (Nd) and Nd:YAG lasers were used as the energy sources. The patients were followed-up from 3 mo to 5 y or more. Patients with basal cell skin cancer treated by irradiation with the Nd laser developed recurrences in 1.8% of cases, and patients treated with the Nd:YAG laser had a recurrence rate of 2.5%. Recurrences following treatment for basal cell skin cancer, and those of squamous cell skin cancer, after irradiation with the Nd laser appeared in 3.7% and 4.4% of patients, respectively. Overall, the frequency of facial skin cancer recurrences after treatment with laser irradiation was 2.1% of all the irradiated tumors. Neodymium laser irradiation is an effective method to treat facial skin cancer of stages T(1-2)N(0)M(0), and results in acceptable cosmetic results.

Paracoccidioidomycosis is a deep, systemic, and progressive mycosis caused by Paracoccidioides brasiliensis. Oral lesions normally are multiples with a mulberry-like appearance. This article reviews an unusual case involving a chronic, solitary, and ulcerated lesion whose clinical aspects were similar to squamous cell carcinoma. Viewed microscopically, the lesion showed pseudoepitheliomatous hyperplasia and non-necrotizing granulomas. The patient was treated with systemic ketoconazole. Over the next 11 years, follow-up examinations were performed but no recurrence was observed.

Multifocal recurrence of in-situ squamous cell cancer of the oral cavity, pharynx and vocal cord following surgical failure can be a therapeutic dilemma. Salvage surgery or radiation may be an option but morbidity can be significant. We evaluated the potential role of low dose Photofrin (1.2mg/Kg) Photodynamic Therapy for this cohort of patients. A total of 25 patients with multifocal recurrent in-situ squamous cell cancer of the oral cavity, pharynx and vocal cord who had failed local resection, and where additional surgery or radiation therapy would likely result in permanent morbidity, were offered Photodynamic Therapy. PDT consisted of off label infusion of Photofrin (1.2mg/kg) followed 48 hours later by illumination at 630nm employing a light diffuser (300J) and/or microlens (150Jcm2). All patients completed their prescribed PDT and no patient has been lost to follow up (minimum 1 year). No photosensitivity reactions were noted. No significant morbidity was seen. All patients were able to maintain oral nutrition. Procedure related pain was well controlled by one week of oral narcotics. At one month post PDT all patients were biopsy negative in the treatment region and no failures within the treatment region have been noted. No fibrosis or permanent PDT morbidity has been seen with follow up to three years. Vocal cord and voice function were excellent. Three patients developed new regions of in-situ disease outside the PDT fields, two underwent additional PDT and one had laser resection. Low dose Photofrin PDT offers excellent palliation and durable local control of recurrent in-situ squamous cell cancers of the oral cavity, pharynx and true cords. This is a well tolerated therapy. Low dose Photofrin appears to improve selectivity and minimize normal tissue injury. It should be tested in a larger patient population.

Epithelial-to-mesenchymal transition is a phenomenon in epithelial tumors that involves loss of intercellular adhesion, mesenchymal phenotype acquisition and enhanced migratory potential. While the epithelial-to-mesenchymal transition process has been extensively linked to metastatic progression of squamous cell carcinoma, studies of the role of epithelial-to-mesenchymal transition in squamous cell carcinoma containing high risk human papillomaviruses are scarce. Moreover, to our knowledge epithelial-to-mesenchymal transition involvement in human penile squamous cell carcinoma, which can arise through transforming HPV infections or independently of HPV, has not been investigated. We evaluated the presence of epithelial-to-mesenchymal transition markers and their relationship to HPV in penile squamous cell carcinoma. We assessed the expression of E-cadherin, vimentin and the epithelial-to-mesenchymal transition related transcription factors Twist, Zeb1 and Snail by immunohistochemical staining in 64 penile squamous cell carcinoma cases. HPV was detected by polymerase chain reaction amplification. Simultaneous loss of membranous E-cadherin expression and vimentin over expression were noted in 43.5% of penile squamous cell carcinoma cases. HPV was significantly associated with loss of membranous E-cadherin but not with epithelial-to-mesenchymal transition. Recurrence and mortality rates were significantly higher in cases showing epithelial-to-mesenchymal transition. Our findings indicate that in penile squamous cell carcinoma epithelial-to-mesenchymal transition is associated with poor prognosis but not with the presence of HPV.

We sought to examine prognostic and therapeutic implications, including cost-effectiveness, of elective neck dissection in the management of patients with clinically-determined T1N0 oral tongue carcinoma. A retrospective review of patients with cT1N0 oral tongue squamous cell carcinoma who underwent surgical extirpation of primary tumor, with or without elective neck dissection, at UCLA Medical Center from 1990 to 2009 was performed. Cox proportional hazards regression was used to assess effects of variables on time to first loco-regional recurrence. A healthcare costs analysis of elective neck dissection was performed by querying the SEER-Medicare linked database. Of the 123 patients identified with cT1N0 squamous cell carcinoma of the oral tongue, 88 underwent elective neck dissection at the time of tumor resection while 35 did not. For all patients, disease-free survival at 3, 5, and 10 years was 93%, 82%, and 79%. Of the 88 patients undergoing elective neck dissection, 20 (23%) demonstrated occult metastatic disease. Male gender, tumor size, perineural invasion, and occult metastatic disease were individually associated with higher rates of loco-regional recurrence. There was no significant difference in loco-regional recurrence between those who underwent elective neck dissection and those who did not (HR=0.76, p=0.52). On cost analysis, neck dissection was not associated with any significant difference in Medicare payments. The high rate of occult metastasis (23%) following elective neck dissection, which did not confer additional healthcare costs, leads to the recommendation of elective neck dissection in patients with cT1N0 oral tongue squamous cell carcinoma.

2001-10-01

The purpose of this study is to report an unusual variant of cervical squamous cell carcinoma, not associated with either human papillomavirus infection or antecedent squamous intraepithelial lesions. Five women had a diagnosis of invasive cervical cancer discovered at hysterectomy performed for prolapse (two cases), leiomyoma (one case), or a vaginal fistula (two cases). The women ranged in age from 47 to 78 years (mean 59 years). Four of the five had a history of normal Papanicolaou (Pap) smears; the other had a Pap smear diagnosis of atypical squamous cells of undetermined significance (ASCUS). All had large cervical tumors (two with parametrial involvement and one with vaginal involvement) that showed extensive keratin formation, an inverted pattern of growth, and, except for one case, minimal cytologic atypia. There was extensive hyperkeratosis and parakeratosis adjacent to each tumor; none had evidence of squamous intraepithelial lesion. Human papillomavirus testing by polymerase chain reaction in situ hybridization and reverse-transcribed polymerase chain reaction in situ was negative in each case, compared with a detection rate of 107 of 108 (99%) for squamous intraepithelial lesion-associated cervical squamous cell and adenocarcinomas. Two of the women died of extensive local recurrence; two other women were recently diagnosed. We conclude that highly differentiated keratinizing squamous cell carcinoma of the cervix is a rare entity not associated with human papillomavirus infection or squamous intraepithelial lesion and thus difficult to detect on routine cervical cancer screening.

Differentiation is a major histological parameter determining tumor aggressiveness and prognosis of the patient; cancer stem cells with their slow dividing and undifferentiated nature might be one of the factors determining the same. This study aims to correlate cancer stem cell markers (CD44 and CD147) with tumor differentiation and evaluate their subsequent effect on prognosis. Immunohistochemical analysis in treatment naïve oral cancer patients (n = 53) indicated that the expression of CD147 was associated with poorly differentiated squamous cell carcinoma and moderately differentiated squamous cell carcinoma (p < 0.01). Furthermore, co-expression analysis showed that 45% each of moderately differentiated squamous cell carcinoma and poorly differentiated squamous cell carcinoma patients were CD44 high /CD147 high as compared to only 10% of patients with well-differentiated squamous cell carcinoma. A three-way analysis indicated that differentiation correlated with recurrence and survival (p < 0.05) in only the patients with CD44 high /CD147 high cohort. Subsequently, relevance of these cancer stem cell markers in patterning the differentiation characteristics was evaluated in oral squamous cell carcinoma cell lines originating from different grades of oral cancer. Flowcytometry-based analysis indicated an increase in CD44 + /CD147 + cells in cell lines of poorly differentiated squamous cell carcinoma (94.35 ± 1.14%, p < 0.001) and moderately differentiated squamous cell carcinoma origin (93.49 ± 0.47%, p < 0.001) as compared to cell line of well-differentiated squamous cell carcinoma origin (23.12% ± 0.49%). Expression profiling indicated higher expression of cancer stem cell and epithelial-mesenchymal transition markers in SCC029B (poorly differentiated squamous cell carcinoma originated; p ≤ 0.001), which was further translated into increased spheroid formation, migration, and invasion (p < 0.001) as compared to cell line of well-differentiated squamous cell carcinoma origin. This study suggests that CD44 and CD147 together improve the prognostic efficacy of tumor differentiation; in vitro results further point out that these markers might be determinant of differentiation characteristics, imparting properties of increased self-renewal, migration, and invasion.

Anal squamous cell carcinoma was a previously uncommon malignancy that has steadily increased in incidence with the increased prevalence of human papillomavirus (HPV) and human immunodeficiency virus (HIV). Anal squamous cell carcinoma is typically characterized by local and regional involvement and distant metastases are far less common. Here, we report a case of a 36-year-old female initially diagnosed with anal squamous cell carcinoma manifesting as an anal mass along with an enlarged inguinal lymph node. After receiving chemoradiation therapy, she remained disease-free until recently, when she presented with an isolated left infraclavicular lymph node found on physical examination followed by a biopsy that was consistent with recurrent anal squamous cell carcinoma. The positron emission tomography-computed tomography (PET-CT) uptake of her original left inguinal lymph node was decreased, suggesting improved regional disease, and no other metastases were found. Our case represents a rare occurrence of metastatic anal squamous cell carcinoma to an isolated distal lymph node and reminds physicians not to forget a unusual site of metastasis and prevent any delay in treatment.

Oral squamous cell carcinoma (OSCC) constitutes 3 percent of all cancers with predominant occurrence in middle aged and elderly males. Tumour recurrence worsens disease prognosis and decreases quality of life in patients with OSCC. Proinflammatory cytokines such as interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-α) have been suggested to play a certain role in variety of tumours. The aim of this study was to investigate the relationship of pretreatment serum IL-6 and TNF-α levels on tumour recurrence in patients with OSCC in order to identify potential biomarkers for the early detection of disease recurrence. The patients with newly diagnosed OSCC were treated and followed from the first visit from November 2006 until January 2008. Serum IL-6 and TNF-α concentrations were measured. The records of the patients were re-examined in July 2012 and data were recorded about cancer characteristics and tumour recurrence. Disease free survival was analyzed by Kaplan-Meier survival curves, log rank test and Cox proportional hazards regression. Serum IL-6 was shown as an independent risk factor for tumour recurrence. Pretreatment serum IL-6 concentration may be a useful biomarker for identification of OSCC patients with increased risk of the disease recurrence.

The head and neck squamous cell carcinoma (HNSCC) population consists mainly of high-risk for recurrence and locally advanced stage patients. Increased knowledge of the HNSCC genomic profile can improve early diagnosis and treatment outcomes. The development of models to identify consistent genomic patterns that distinguish HNSCC patients that will recur and/or develop metastasis after treatment is of utmost importance to decrease mortality and improve survival rates. In this study, we used array comparative genomic hybridization data from HNSCC patients to implement a robust model to predict HNSCC recurrence/metastasis. This predictive model showed a good accuracy (>80%) and was validated in an independent population from TCGA data portal. This predictive genomic model comprises chromosomal regions from 5p, 6p, 8p, 9p, 11q, 12q, 15q and 17p, where several upstream and downstream members of signaling pathways that lead to an increase in cell proliferation and invasion are mapped. The introduction of genomic predictive models in clinical practice might contribute to a more individualized clinical management of the HNSCC patients, reducing recurrences and improving patients' quality of life. The power of this genomic model to predict the recurrence and metastases development should be evaluated in other HNSCC populations.

Purpose: Head and neck squamous cell carcinomas (HNSCCs) cause more than 300,000 deaths worldwide each year. Locoregional and distant recurrences represent worse prognostic events and accepted surrogate markers of patients' overall survival. No valid biomarker and salvage therapy exist to identify and treat patients at high-risk of recurrence. We aimed to verify if selected miRNAs could be used as biomarkers of recurrence in HNSCC. Experimental Design: A NanoString array was used to identify miRNAs associated with locoregional recurrence in 44 patients with HNSCC. Bioinformatic approaches validated the signature and identified potential miRNA targets. Validation experiments were performed using an independent cohort of primary HNSCC samples and a panel of HNSCC cell lines. In vivo experiments validated the in vitro results. Results: Our data identified a four-miRNA signature that classified HNSCC patients at high- or low-risk of recurrence. These miRNAs collectively impinge on the epithelial-mesenchymal transition process. In silico and wet lab approaches showed that miR-9, expressed at high levels in recurrent HNSCC, targets SASH1 and KRT13, whereas miR-1, miR-133, and miR-150, expressed at low levels in recurrent HNSCC, collectively target SP1 and TGFβ pathways. A six-gene signature comprising these targets identified patients at high risk of recurrences, as well. Combined pharmacological inhibition of SP1 and TGFβ pathways induced HNSCC cell death and, when timely administered, prevented recurrence formation in a preclinical model of HNSCC recurrence. Conclusions: By integrating different experimental approaches and competences, we identified critical mediators of recurrence formation in HNSCC that may merit to be considered for future clinical development.

Cutaneous malignancy is associated with worse outcomes in patients with chronic lymphocytic leukemia (CLL). We sought to identify the incidence and recurrence rate of nonmelanoma skin cancer (NMSC) in patients with non-Hodgkin lymphoma (NHL). NMSC incidence was calculated and Cox proportional hazards models were used to evaluate associations with risk of recurrence for patients with NHL between 1976 and 2005 who were in the Rochester Epidemiology Project research infrastructure. We identified 282 patients with CLL or small lymphocytic lymphoma and 435 with non-CLL NHL. The incidence of basal cell carcinoma and squamous cell carcinoma was 1829.3 (95% confidence interval [CI] 1306.7-2491.1) and 2224.9 (95% CI 1645.9-2941.6), respectively, in patients with CLL. The cumulative recurrence rate at 8 years after treatment with Mohs micrographic surgery was 8.3% (95% CI 0.0%-22.7%) for basal cell carcinoma and 13.4% (95% CI 0.0%-25.5%) for squamous cell carcinoma in patients with CLL. This was a retrospective cohort study. After Mohs micrographic surgery and standard excision of NMSC, patients with NHL had a skin cancer recurrence rate that was higher than expected. Careful treatment and monitoring of patients with NHL and NMSC are warranted. Copyright © 2014 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

Chemoradiotherapy for esophageal squamous cell cancer.

PubMed

Sasaki, Yusuke; Kato, Ken

2016-09-01

Chemoradiotherapy has been clinically indicated for patients with resectable esophageal squamous cell carcinoma who refuse surgical resection and in locally advanced unresectable esophageal squamous cell carcinoma patients. Concurrent chemoradiotherapy prolongs survival than radiation therapy alone when given as definitive treatment. Therefore, chemoradiotherapy is recognized as the standard non-invasive treatment for patients with localized esophageal cancer who opt for non-surgical treatment. JCOG9906 showed promising outcomes for stage II/III ESCC patients. But there are some problems about chemoradiotherapy for esophageal squamous cell carcinoma. Late toxicities are sometimes lethal for patients who achieved complete response even after years. Salvage treatment for residual or recurrent disease is unestablished. Modified Radiation Therapy Oncology Group regimen at the dose of 50.4 Gy reduced late toxicities without reducing efficacy. Optimal timings and procedure of salvage surgery and endoscopic therapy is evaluated in JCOG0909. Strategy including salvage therapy after chemoradiotherapy should be considered at the time of starting the treatment. Targeted therapy has not shown adding effect for chemoradiotherapy for esophageal squamous cell carcinoma yet. New agents, such as immune checkpoint inhibitors, are expected to show synergistic effect with chemoradiotherapy for esophageal squamous cell carcinoma. Further investigation is needed. © The Author 2016. Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

Patients with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) demonstrate aberrant activation of the phosphotidylinositol-3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway. We examined the efficacy of everolimus, an mTOR inhibitor, in patients with recurrent or metastatic HNSCC. This single-arm phase II study enrolled biomarker-unselected patients with recurrent or metastatic HNSCC who failed at least 1 prior therapy. Everolimus was administered until progressive disease or unacceptable toxicity. Primary endpoint was clinical benefit rate (CBR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), and evaluation of tissue and serum biomarkers related to the PIK3CA pathway. Seven of 9 patients treated in the first stage were evaluable. No objective responses were seen; CBR was 28%. Three patients discontinued everolimus because of toxicity. Median PFS and OS were 1.5 and 4.5 months, respectively. No activating PI3K mutations were identified in available tumor tissue. Everolimus was not active as monotherapy in unselected patients with recurrent/metastatic HNSCC. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1759-1764, 2016. © 2016 Wiley Periodicals, Inc.

The purpose of the present study was to identify variables associated with high risk of failure in patients with locally advanced squamous cell carcinoma of the oral cavity (SCC-OC). This retrospective study included 191 patients with stage III-IVb SCC-OC treated with post-operative radiotherapy (RT) or chemoradiotherapy (CRT) between 1995 and 2013. Disease-free (DFS) and overall survival (OS) were analyzed; variables associated with inferior DFS were identified. Seventy-five patients (39%) recurred. DFS and five-year OS were 52% and 54%, respectively. Poorly differentiated tumors (p=0.03), recurrent tumors (p=0.02) and high nodal ratio (p=0.02) were associated with an increased risk of recurrence. CRT was associated with improved DFS in patients with positive margins and/or extracapsular extension (p=0.021). Tumors that are recurrent, high grade, or have high nodal ratio are at risk of recurrence. Presence of these disease features should be taken into consideration for better risk stratification.

Pyropheophorbide-a-hexyl ether (HPPH) is a new photosensitizer for use with photodynamic therapy (PDT) that has shown promise in laboratory animals. PDT, using this drug, is being used to treat canine patients afflicted with hemangiopericytoma and oral squamous cell carcinoma (SCC) at the University of Missouri-Columbia College of Veterinary Medicine. To date, 11 dogs with hemangiopericytoma and 5 dogs with oral SCC have been treated using a combination of surgery and PDT. Thus far, there have been no serious complications attributable to the treatment. Two dogs have had recurrences of the hemangiopericytoma and there have been no recurrences of SCC with a median follow time of 5 months. Both recurrent hemangiopericytomas were in patients with large tumors that had previous surgery. This study is ongoing and no conclusions have been reached; however several observations are noted. It appears that PDT using HPPH is safe is dogs, and may decrease the recurrence rate of Hemangiopericytomas. In dogs with oral SCC, the treatment is effective is causing necrosis and sloughing of the tumor tissue, and recurrences have not been noted on follow-ups up to 6 months.

Anal sac squamous cell carcinoma (SCC) is a rare tumor in dogs. Only eight cases have been described in the literature, and previous reports of treatment only describe surgery or palliative treatment with non-steroidal anti-inflammatory drugs. We report a case of a 12-year-old female neutered Labrador with locally advanced anal sac SCC. The dog was treated with four cycles of carboplatin 300 mg/m2 and four weekly fractions of 8.5 Gy radiation. The dog achieved a complete response, and one year later the dog is still alive and well with no evidence of tumor recurrence. Radiotherapy in combination with carboplatin chemotherapy was effective in the long-term control of this rare disease. PMID:29056703

To investigate whether the extent of expression of hyaluronan (HA) and epidermal growth factor receptor (EGFR) in squamous cell carcinoma of the mobile tongue can predict the risk of cervical metastasis and survival. Retrospective histopathologic study. Surgical specimens from 64 patients who had undergone surgery for squamous cell carcinoma of the mobile tongue were assessed using immunohistochemistry to investigate the expression of HA and EGFR in the primary tumours, and the data were then correlated to cervical metastasis and survival. There was a significant correlation between the intensity of HA staining and patient survival (p .024), and a weak correlation between the staining proportion of EGFR and the risk for regional recurrence (AUC 66). This study indicates that immunoscoring using HA could be used to provide prognostic tools for tongue cancer, and that it might be of interest to study the prognostic properties of EGFR further concerning the risk for regional recurrence after the primary treatment.

Purpose The Gynecologic Oncology Group (GOG) conducted a phase II trial to assess the efficacy and tolerability of the anti-EGFR antibody cetuximab, in persistent or recurrent carcinoma of the cervix. Patients and Methods Eligible patients had cervical cancer, measurable disease, and GOG performance status ≤2. Treatment consisted of cetuximab 400 mg/m2 initial dose followed by 250 mg/m2 weekly until disease progression or prohibitive toxicity. The primary endpoints were progression-free survival (PFS) at 6 months and response. The study used a 2-stage group sequential design. Results Thirty-eight patients were entered with 3 exclusions, leaving 35 evaluable for analysis. Thirty-one patients (88.6%) received prior radiation as well as either 1 (n = 25, 71.4%) or 2 (n = 10) prior cytotoxic regimens. Twenty-four patients (68.6%) had a squamous cell carcinoma. Grade 3 adverse events possibly related to cetuximab included dermatologic (n = 5), GI (n = 4), anemia (n = 2), constitutional (n = 3), infection (n = 2), vascular (n = 2), pain (n = 2), and pulmonary, neurological, vomiting and metabolic (n = 1 each). No clinical responses were detected. Five patients (14.3%; two-sided 90% CI, 5.8% to 30%) survived without progression for at least 6 months. The median PFS and overall survival (OS) times were 1.97 and 6.7 months, respectively. In this study, all patients with PFS at 6 months harbored tumors with squamous cell histology. Conclusion Cetuximab is well tolerated but has limited activity in this population. Cetuximab activity may be limited to patients with squamous cell histology. PMID:21684583

Clinical and biological significance of stem-like CD133(+)CXCR4(+) cells in esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma is one of the most frequent malignant tumors. Cancer stem cells are considered to be responsible for tumor growth, metastasis, and recurrence. Cluster of differentiation 133 (CD133) and C-X-C chemokine receptor type 4 (CXCR4) are frequently applied markers for the identification and isolation of cancer stem cells. However, few studies have investigated the coexpression of CD133 and CXCR4 in esophageal squamous cell carcinoma. This study aims to explore the clinical and biological role of stem-like CD133(+)CXCR4(+) cells in esophageal squamous cell carcinoma. Immunohistochemical staining was performed to detect the expression of CD133 and CXCR4 in esophageal squamous cell carcinoma tissues of patients. Flow cytometry and fluorescence-activated cell sorting were applied to analyze and isolate each subgroup in esophageal squamous cell carcinoma cell line TE-1. The characteristic differences between each subgroup were assayed in vitro. The association between CD133/CXCR4 expression and patients' prognosis was analyzed by Kaplan-Meier and Cox regression. Among 154 patient tissues, concomitant high CD133-CXCR4 expression accounts for 20.78% (32/154). In vitro, CXCR4(+) cells (CD133(+)CXCR4(+) and CD133(-)CXCR4(+)) showed high invasive potential and CD133(+)CXCR4(+) cells showed high proliferative capacity. Clinically, patients with concomitant high CD133-CXCR4 expression had decreased disease-free survival and overall survival (P < .01). Esophageal squamous cell carcinoma cells coexpressing CD133 and CXCR4 possess the characteristics of cancer stem cells. The concomitant high CD133-CXCR4 expression might be a novel marker for predicting the poor prognosis of patients with esophageal squamous cell carcinoma, and CD133 and CXCR4 may serve as potential therapeutic targets.

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'Does cervical lymph node recurrence after oesophagectomy or definitive chemoradiotherapy for thoracic oesophageal squamous cell carcinoma benefit from salvage treatment?' Altogether, 659 articles were found using the reported search, of which 8 represented the best evidence to answer the clinical question. The authors, journal, date, country of publication, patient group studied, study type, relevant outcomes and results of these articles were tabulated. All were retrospective or institutional reports. Seven of the 8 articles suggested that cervical lymphadenectomy (LD) or multimodal treatment with LD and radiotherapy (RT)/chemoradiotherapy (CRT) was associated with good outcomes in patients with cervical lymph node (LN) recurrence after curative oesophagectomy for thoracic oesophageal squamous cell carcinoma (ESCC). Salvage cervical LD was the main treatment and could achieve locoregional disease control and prolonged survival. It was safe with no postoperative mortality, although minor LD complications such as recurrent laryngeal nerve palsy were observed. Most reports highlighted that a solitary cervical LN relapse after curative oesophagectomy could be considered a good prognostic indicator for salvage cervical LD or multimodal treatment. Patients with microscopic residual tumour after salvage cervical LD or suspected extensive metastasis might benefit from a combination of LD and CRT. One article described salvage RT alone, again with a positive effect on survival. Conversely, data suggested that salvage LD in patients after definitive CRT for thoracic ESCC was not likely to control locoregional disease. © The Author 2017.

To report three cases of canine corneal squamous cell carcinoma (SCC) treated with strontium 90 beta radiation as an adjunct to surgical excision. Corneal SCC was excised with lamellar keratectomy. This was followed by local application of strontium 90 beta radiation. Available case follow-up times range from 3 to 50 months. One case suffered a recurrence 5 months following initial excision and strontium 90 treatment. Strontium 90 beta radiation has been used extensively as an adjunctive treatment for equine corneal SCC and in other canine ocular tumors; however, there is a paucity of information regarding use in canine corneal SCC. The cases presented here suggest its use following keratectomy may be helpful in preventing disease recurrence. At the dosage used, severe adverse effects were not observed. © 2014 American College of Veterinary Ophthalmologists.

Despite advances in interdisciplinary treatment protocols, the chance of cure for recurrent head and neck squamous cell carcinoma (HNSCC) following failed primary therapy is poor and often entails a high morbidity. Recurrence rates vary widely in the literature depending on tumor localization, primary tumor stage, and treatment modality, and only a minority of patients can be salvaged. Historical cohort study. This study valuates the outcomes of patients treated for recurrent squamous cell carcinoma of the larynx, pharynx, and oral cavity in the largest tertiary referral center of Switzerland to find predictors for survival in salvage surgery with curative intent. Included were 176 consecutive patients with recurrent disease after primary curative treatment of HNSCC, in locations mentioned previously. Kaplan-Meier survival analyses with log-rank testing were performed depending on T and N stage, gender, treatment, and location of first relapse to evaluate the impact on overall survival, disease specific survival, and recurrence free survival. Overall successful salvage rates were 49.2% for laryngeal recurrence, 35.1% for oral cavity, 32.7% for oropharyngeal, and a mere 17.4% for hypopharyngeal recurrences. Predictive factors for better outcome were location of recurrence, female gender, lymph node status, and extent of salvage treatment. In case of recurrent disease, laryngeal cancers showed the best salvage rates, whereas in hypopharyngeal relapses, very few patients could be successfully salvaged. Patients therefore should be carefully selected and counseled for salvage treatment according to patient motivation, age, type of previous treatment, surgical resectability, and exclusion of distant recurrence. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Cancer stem cells in head and neck squamous cell carcinoma: a review.

Research indicates that a small population of cancer cells is highly tumorigenic, endowed with the capacity for self-renewal, and has the ability to differentiate into cells that constitute the bulk of tumors. These cells are considered the "drivers" of the tumorigenic process in some tumor types, and have been named cancer stem cells (CSC). Epithelial-mesenchymal transition (EMT) appears to be involved in the process leading to the acquisition of stemness by epithelial tumor cells. Through this process, cells acquire an invasive phenotype that may contribute to tumor recurrence and metastasis. CSC have been identified in human head and neck squamous cell carcinomas (HNSCC) using markers such as CD133 and CD44 expression, and aldehyde dehydrogenase (ALDH) activity. Head and neck cancer stem cells reside primarily in perivascular niches in the invasive fronts where endothelial-cell initiated events contribute to their survival and function. Clinically, CSC enrichment has been shown to be enhanced in recurrent disease, treatment failure and metastasis. CSC represent a novel target of study given their slow growth and innate mechanisms conferring treatment resistance. Further understanding of their unique phenotype may reveal potential molecular targets to improve therapeutic and survival outcomes in patients with HNSCC. Here, we discuss the state-of-the-knowledge on the pathobiology of cancer stem cells, with a focus on the impact of these cells on head and neck tumor progression, metastasis and recurrence due to treatment failure.

Christiansen, Hans; Hermann, Robert Michael; Martin, Alexios

Purpose: The aim of this study was to evaluate the efficacy of adjuvant radiotherapy after transoral laser microsurgery for advanced recurrent head-and-neck squamous cell carcinoma (HNSCC). Patients and Methods: Between 1988 and 2000, 37 patients with advanced local recurrences (23 local and 14 locoregional recurrences) of HNSCC without distant metastases were treated in curative intent with organ-preserving transoral laser microsurgery and adjuvant radiotherapy (before 1994 split-course radiotherapy with carboplatinum, after 1994 conventional radiotherapy). Initial therapy of the primary (8.1% oral cavity, 35.1% oropharynx, 13.5% hypopharynx, and 43.3% larynx) before relapse was organ-preserving transoral laser microsurgery without any adjuvant therapy. Results:more » After a median follow-up of 124 months, the 5-year overall survival rate was 21.3%, the loco-regional control rate 48.3%, respectively. In multivariate analysis, stage of original primary tumor (Stage I/II vs. Stage III/IV), and patient age (<58 years vs. {>=}58 years) showed statistically significant impact on prognosis. In laryngeal cancer, larynx preservation rate after treatment for recurrent tumor was 50% during follow-up. Conclusion: Our data show that organ-preserving transoral laser microsurgery followed by adjuvant radiotherapy is a curative option for patients who have advanced recurrence after transoral laser surgery and is an alternative to radical treatment.« less

Acquired chromosomal aberrations, including gene copy number alterations, are involved in the development and progression of human malignancies. SOX2, a transcription factor-coding gene located at 3q26.33, is known to be recurrently and specifically amplified in squamous cell carcinomas of the lung, the esophagus, and the oral cavity. In these organs, the SOX2 protein plays an important role in tumorigenesis and tumor survival. The aim of this study was to determine whether SOX2 amplification is also found in squamous cell carcinomas in other organs commonly affected by this tumor entity. In addition, we examined a large spectrum of lung cancer entities with neuroendocrine differentiation (ie, small cell cancers, large cell cancers, typical and atypical carcinoids) for SOX2 and TTF1 copy number gains to reveal potential molecular ties to squamous cell carcinomas or adenocarcinomas of the lung. Applying fluorescence in situ hybridization, we assessed squamous cell carcinomas of the cervix uteri (n = 47), the skin (n = 57), and the penis (n = 53) for SOX2 copy number alterations and detected amplifications in 28%, 28%, and 32% of tumors, respectively. Furthermore, we performed immunohistochemical SOX2 staining and found that SOX2 amplification is significantly associated with overexpression of the corresponding protein in squamous cell carcinomas (P < .001). Of the lung cancer entities with neuroendocrine differentiation, only small cell cancers and large cell cancers exhibited SOX2 or TTF1 amplifications at significant frequencies, indicating that at least a subset of these might be dedifferentiated forms of squamous cell carcinomas or adenocarcinomas of the lung. We conclude that SOX2 amplification and consequent SOX2 protein overexpression may represent important mechanisms of tumor initiation and progression in a considerable subset of squamous cell carcinomas.

Epidermal squamous cell carcinoma is an extremely common type of cancer. Early tumors can be successfully treated by surgery, but recurrent disease is aggressive and resistant to therapy. Cisplatin is often used as a treatment, but the outcome is rarely satisfactory. For this reason new strategies are required. Sulforaphane is a diet-derived cancer prevention agent that is effective in suppressing tumor growth in animal models of skin cancer. We monitored the efficacy of sulforaphane and cisplatin as a combined therapy for squamous cell carcinoma. Both agents suppress cell proliferation, growth of cancer stem cell spheroids, matrigel invasion and migration of SCC-13 and HaCaT cells, and combination treatment is more efficient. In addition, SCC-13 cell derived cancer stem cells are more responsive to these agents than non-stem cancer cells. Both agents suppress tumor formation, but enhanced suppression is observed with combined treatment. Moreover, both agents reduce the number of tumor-resident cancer stem cells. SFN treatment of cultured cells or tumors increases apoptosis and p21 Cip1 level, and both agents increase tumor apoptosis. We suggest that combined therapy with sulforaphane and cisplatin is efficient in suppressing tumor formation and may be a treatment option for advanced epidermal squamous cell carcinoma. © 2017 Wiley Periodicals, Inc.

The current eighth tumor node metastasis lymph node category pathologic lymph node staging system for esophageal squamous cell carcinoma is based solely on the number of metastatic nodes and does not consider anatomic distribution. We aimed to assess the prognostic capability of the eighth tumor node metastasis pathologic lymph node staging system (numeric-based) compared with the 11th Japan Esophageal Society (topography-based) pathologic lymph node staging system in patients with esophageal squamous cell carcinoma. We retrospectively reviewed the clinical records of 289 patients with esophageal squamous cell carcinoma who underwent esophagectomy with extended lymph node dissection during the period from January 2006 through June 2016. We compared discrimination abilities for overall survival, recurrence-free survival, and cancer-specific survival between these 2 staging systems using C-statistics. The median number of dissected and metastatic nodes was 61 (25% to 75% quartile range, 45 to 79) and 1 (25% to 75% quartile range, 0 to 3), respectively. The eighth tumor node metastasis pathologic lymph node staging system had a greater ability to accurately determine overall survival (C-statistics: tumor node metastasis classification, 0.69, 95% confidence interval, 0.62-0.76; Japan Esophageal Society classification; 0.65, 95% confidence interval, 0.58-0.71; P = .014) and cancer-specific survival (C-statistics: tumor node metastasis classification, 0.78, 95% confidence interval, 0.70-0.87; Japan Esophageal Society classification; 0.72, 95% confidence interval, 0.64-0.80; P = .018). Rates of total recurrence rose as the eighth tumor node metastasis pathologic lymph node stage increased, while stratification of patients according to the topography-based node classification system was not feasible. Numeric nodal staging is an essential tool for stratifying the oncologic outcomes of patients with esophageal squamous cell carcinoma even in the cohort in which adequate numbers of lymph nodes were harvested.

The prognoses of submucosal esophageal squamous cell carcinoma patients vary. Patients with favorable prognoses may receive less invasive or nonsurgical interventions, whereas patients with poor prognoses or advanced esophageal cancer may require aggressive treatments. We sought to identify prognostic factors for patients with submucosal esophageal squamous cell carcinoma, focusing on lymph node metastasis and recurrence. We included 137 submucosal esophageal squamous cell carcinoma patients who had undergone transthoracic esophagectomy with systematic extended lymph node dissection. Submucosal tumors were classified as SM1, SM2, and SM3 according to the depth of invasion. Prognostic factors were determined by univariable and multivariable analyses. Lymph node metastasis was observed in 18.8%, 30.5%, and 50.0% of SM1, SM2, and SM3 cases, respectively. The overall 5-year recurrence rate was 21.9%; the rates for SM1, SM2, and SM3 tumors were 9.4%, 18.6%, and 34.8%, respectively. The SM1 tumors all recurred locoregionally; distant metastasis occurred in SM2 and SM3 cases. The 5-year overall survival rates were 83%, 77%, and 59% for SM1, SM2, and SM3 cases, respectively. On univariable analysis, lymph node metastasis, depth of submucosal invasion (SM3 versus SM1/2), and tumor location (upper thoracic versus mid/lower thoracic) were poor prognostic factors for overall survival. Multivariable Cox regression analyses identified depth of submucosal invasion (hazard ratio 2.51, 95% confidence interval: 1.37 to 4.61) and tumor location (hazard ratio 2.43, 95% confidence interval: 1.18 to 4.63) as preoperative prognostic factors. Tumor location (upper thoracic) and infiltration (SM3) are the worse prognostic factors of submucosal esophageal squamous cell carcinoma, but lymph node metastasis is not a predictor of poorer prognosis.

Head and neck squamous cell carcinoma shows high prevalence of lymph node metastasis at diagnosis, and despite the advances in treatment, the overall 5-year survival is still under 50%. Chemokine receptors have a role in the development and progression of cancer, but their effect in head and neck carcinoma remains poorly characterised. This study aimed to assess the prognostic value of CCR1, CCR3, CCR4, CCR5, CCR7 and CXCR4 in head and neck squamous cell carcinomas. Immunohistochemical expression of chemokine receptors was evaluated in a retrospective cohort of 76 cases of head and neck squamous cell carcinoma. Clinicopathological associations were analysed using the chi-square test, survival curves were analysed according to the Kaplan-Meier method, and the Cox proportional hazard model was applied for multivariate survival analysis. The chemokine receptors were highly expressed in primary carcinomas, except for CCR1 and CCR3. Significant associations were detected, including the associations between CCR5 expression and lymph node metastasis (N stage, P = .03), advanced clinical stage (P = .003), poor differentiation of tumours (P = .05) and recurrence (P = .01). The high expression of CCR5 was also associated with shortened disease-free survival (HR: 2.85, 95% CI: 1.09-8.14, P = .05), but the association did not withstand the Cox multivariate survival analysis. At univariate analysis, high expression of CCR7 was associated with disease-free survival and low levels of CXCR4 were significantly associated with both disease-specific and disease-free survival. These findings show that chemokine receptors may have an important role in head and neck squamous cell carcinoma progression, regional lymph node metastasis and recurrence. © 2018 John Wiley & Sons A/S.

Laryngeal squamous cell carcinoma (LSCC) prognosis is definitely related to lymph node metastasis. Epithelial-mesenchymal transition (EMT) allows neoplastic cells to gain the plasticity and motility required for tumour progression and metastasis. The aim of this study was to investigate the role of EMT in the prognosis of LSCC. Immunohistochemical analysis of E-cadherin, N-cadherin, Snail, Slug, ZEB1, and ZEB2 was performed in 37 consecutive LSCC cases. Low E-cadherin levels and high Slug levels correlated with both disease recurrence (P = 0.02 and P =0.01, respectively) and shorter disease-free survival (DFS) (P = 0.04 and P = 0.02, respectively). Relative expression levels of CDH1, SNAI2, miR-1 and the miR-200 family were also evaluated. CDH1, miR-200a and miR-200c down-regulation and SNAI2 overexpression were significantly associated with disease recurrence (P = 0.03, P = 0.02, P = 0.04, and P = 0.04, respectively). EMT increases tumour recurrence risk and shortens DFS in LSCC. E-cadherin and Slug immunohistochemical analysis could be useful for identifying patients requiring more aggressive treatment after surgery. © 2015 John Wiley & Sons Ltd.

Sixteen of 46 patients (35%) with Grade 3 vulvar intraepithelial neoplasia (VIN 3) were found to have an additional site of lower genital tract squamous cell neoplasia, primarily in the cervix. The frequency of multicentricity decreased significantly with age. In addition, patients with multicentric disease (involving the vagina and/or cervix in addition to the vulva) had a significantly higher frequency of multifocal disease involving the vulva (involving more than one location on the vulva) and of recurrence than patients without multicentric disease. Human papillomavirus (HPV) DNA was detected by in situ hybridization in 81% of the women with multicentric squamous cell neoplasia. No significant difference was noticed between patients with multicentric and unicentric squamous cell neoplasia in the detection rate of papillomavirus antigen, HPV DNA, the various HPV types, herpes simplex virus Type 2 (HSV2)-related antigen, type-specific antibodies to HSV, and dual HPV and HSV2 infections. These findings suggest that HPV and HSV2, although strongly associated with VIN 3, do not influence the development pattern of squamous cell neoplasia, and that all patients with VIN 3, especially if they are younger than 50 years of age, should be evaluated periodically for additional centers of lower genital tract squamous cell neoplasia.

Esophageal squamous cell carcinoma is one of the deadliest of all the cancers. Its metastatic properties portend poor prognosis and high rate of recurrence. A more advanced method to identify new molecular biomarkers predicting disease prognosis can be whole exome sequencing. Here, we report the most effective genetic variants of the Notch signaling pathway in esophageal squamous cell carcinoma susceptibility by whole exome sequencing. We analyzed nine probands in unrelated familial esophageal squamous cell carcinoma pedigrees to identify candidate genes. Genomic DNA was extracted and whole exome sequencing performed to generate information about genetic variants in the coding regions. Bioinformatics software applications were utilized to exploit statistical algorithms to demonstrate protein structure and variants conservation. Polymorphic regions were excluded by false-positive investigations. Gene-gene interactions were analyzed for Notch signaling pathway candidates. We identified novel and damaging variants of the Notch signaling pathway through extensive pathway-oriented filtering and functional predictions, which led to the study of 27 candidate novel mutations in all nine patients. Detection of the trinucleotide repeat containing 6B gene mutation (a slice site alteration) in five of the nine probands, but not in any of the healthy samples, suggested that it may be a susceptibility factor for familial esophageal squamous cell carcinoma. Noticeably, 8 of 27 novel candidate gene mutations (e.g. epidermal growth factor, signal transducer and activator of transcription 3, MET) act in a cascade leading to cell survival and proliferation. Our results suggest that the trinucleotide repeat containing 6B mutation may be a candidate predisposing gene in esophageal squamous cell carcinoma. In addition, some of the Notch signaling pathway genetic mutations may act as key contributors to esophageal squamous cell carcinoma.

The goal of this study was to investigate the expression of some metalloendopeptidases in squamous cell carcinomas of the oropharynx as well as its relation to histological differentiation, staging of disease, and prognosis. Paraffin blocks from 21 primary tumors were obtained from archives of the Department of Pathology, Paulista Medical School, Federal University of Sao Paulo, UNIFESP/EPM. Immunohistochemistry was used to detect the expression of EP24.15 and EP24.16 by means of tissue microarrays. Expression of EP24.15 or EP24.16 was not correlated with the stage of disease, histopathological grading or recurrence in squamous cell carcinomas of the oropharynx. In summary, our results support the notion that EP24.15 and EP24.16 are expressed in carcinoma of the oropharynx; however, these do not appear to be suitable biomarkers for histological grading, disease stage or recurrence as depicted by tissue microarrays and immunohistochemistry.

To analyze the pattern of lymphatic metastasis in middle thoracic esophageal squamous cell carcinoma (ESCC) with different T staging and to investigate the clinical value of para-recurrent laryngeal nerve lymphadenectomy. Clinicopathological data of 717 patients with middle thoracic ESCC undergoing Mckeown esophagectomy plus three-field lymph node dissection in Fujian Provincial Hospital from January 1999 to December 2007 were analyzed retrospectively. Lymph node metastatic rates of different T stages were calculated. Clinical value of each station lymphadenectomy, especially the para-recurrent laryngeal nerve lymphadenectomy, was evaluated by the efficacy index (EI, cross product of one station metastatic rate and 5-year survival of patient with positive lymph nodes of above station). Rates of lymph node metastasis were 29.0% (18/62), 61.1% (91/149) and 64.8% (328/506) in stage T1, T2 and T3 patients respectively. Despite T staging, metastatic rates of right para-recurrent laryngeal nerve lymph node (rRLN LN) were 21.0% (13/62), 28.9% (43/149) and 29.4% (149/506) in stage T1, T2 and T3 patients respectively, which was the most common among all lymph node stations. Metastatic rates of left para-recurrent laryngeal nerve lymph node (lRLN LN) were the second, with 8.1% (5/62), 17.4% (26/149) and 24.7% (125/506) in stage T1, T2, T3 patients respectively. Follow-up period lasted more than 5 years. The 5-year survival rates of positive rRLN LN were 53.8%, 39.5% and 32.2% in stage T1, T2 and T3 patients respectively, whose EI values were 11.3, 11.4 and 9.5 respectively. The 5-year survival rates of positive lRLN LN were 40.0%, 34.6% and 40.0% in stage T1, T2 and T3 patients respectively, whose EI values were 3.2, 6.0 and 9.9 respectively. Bilateral para-recurrent laryngeal nerve lymph nodes are the common sites of metastasis in middle thoracic esophageal squamous cell carcinoma. Right para-recurrent laryngeal nerve lymphadenectomy is of high clinical value despite the T staging. Left para-recurrent laryngeal nerve lymphadenectomy has better efficacy in stage T2 and T3 patients, but is limited in stage T1 patients.

The purpose of this study was to determine the effect of postoperative radiotherapy (PORT) on recurrence and survival in patients with oral squamous cell carcinoma (OSCC) of intermediate recurrence risk. Intermediate risk patients, defined as pT1, pT2, pN0, or pN1 with at least one adverse pathological feature (eg, lymphovascular/perineural invasion), were identified from the head and neck databases of the Liverpool Head and Neck Cancer Unit and the Sydney Head and Neck Cancer Institute. Patients who received surgery and PORT were case matched with patients treated by surgery alone based on pN, pT, margins, and pathological features. Ninety patients were matched into 45 pairs. There was significant improvement (P = .039) in locoregional control with PORT (84%) compared with surgery alone (60%), which was concentrated in the pN1 subgroup (P = .036), but not the pN0 subgroup (P = .331). PORT significantly improves locoregional control for intermediate risk OSCC. © 2017 Wiley Periodicals, Inc.

Altered microRNA expression has been found in many cancer types, including laryngeal squamous cell carcinoma (LSCC). We investigated the association of LSCC-related miR-34c-5p with disease-free survival and overall survival. Retrospective cohort study. Expression levels of miR-34c-5p were detected in 90 LSCC formalin-fixed paraffin-embedded tissues by reverse-transcription quantitative polymerase chain reaction. Overall survival and disease-free survival were evaluated using the Kaplan-Meier method, and multivariate analysis was performed using Cox proportional hazard analysis. A downregulation of miR-34c-5p expression significantly correlated with worse disease-free and overall survival. In the multivariate analysis, low miR-34c-5p expression was associated with an increased risk of recurrence. A downregulation of miR-34c-5p in LSCC is independently associated with unfavorable disease-free survival, suggesting that miR-34c-5p might be a promising marker for evaluating the risk of recurrences.

Spontaneous excavation of primary lung cancer is common; however cavitation of metastatic lung lesions is rare and usually confused with benign lesions. In Moroccan context tuberculosis is the first suspected diagnosis of lung excavations. We report a rare case of cavitary lung metastasis of a uterine cervix cancer, treated initially as tuberculosis. A 40-year old non-smoking woman with a known history of squamous cell carcinoma of the uterine cervix since August 2005; presented on September 2008 with right chest pain without fever, hemoptysis or weight loss. CT scan showed a thin walled cavity. Empirical Antibiotic therapy was conducted 15 days with poor outcome. Then antibacillary treatment was started with no proof of mycobacterial infection. A month later, the patient presented with gynecological bleeding and a pneumothorax. Bronchoscopy with transbronchial biopsy of the cavitary mass was performed. Pathology demonstrated a metastatic squamous cell carcinoma. Pelvic examination and MRI showed a subsequent local cervix recurrence. Patient underwent 3 courses of systemic chemotherapy. She died on June 2009 due to progressive disease. Even cavitary lung metastases are rare and benign differential diagnosis are more common, clinician should be careful in neoplastic context and investigation should be done to eliminate a recurrence.

The objective of this study was to evaluate the implication of human telomerase reverse transcriptase (hTERT) in cervical carcinogenesis and cancer recurrence. One hundred three cases of uterine cervix, including 20 normal, 13 low-grade squamous intraepithelial lesion (LSIL), 30 high-grade squamous intraepithelial lesion (HSIL), and 40 squamous cell carcinoma (SCC) tissues, were evaluated for hTERT immunoreactivity. The expressions of hTERT in normal, LSIL, HSIL, and SCC tissues were compared by Fisher exact or Chi-square test. The relationships between hTERT and clinicopathologic variables of SCC were also assessed. Furthermore, SCC patients were subdivided into negative and positive hTERT expression subgroups, and Kaplan-Meier curves were used to plot the cumulative recurrence hazard for 5 years. There was a significant difference for hTERT expression between LSIL and HSIL subgroups (P < 0.001) but no significant difference between normal and LSIL as well as HSIL and SCC subgroups. For SCC patients, hTERT expression was positive in lymph nodes, vagina, and parametrium metastastic cases. However, it did not reach a significant difference. The cumulative recurrence hazard for 5 years was about 29% in positive hTERT expression subgroup compared to 0% in negative hTERT subgroup (P = 0.2866). In conclusion, a point stage of HSIL exists in the progression of cervical carcinogenesis when the hTERT expression increases significantly. Moreover, SCC patients with positive hTERT expression may have higher cumulative recurrence hazard.

Seven (87.5%) of the women had an initial complete response; however, three subsequently developed recurrence after the treatment was stopped. They were retreated, and two of these three patients achieved a subsequent complete response. The overall response to therapy was 75% (6/8) with the six women off therapy from 1.1 to 6.9 years. Total follow-up of all patients was 3.1 to 6.9 years with no patients having developed invasive carcinoma. Because of the highmore » success rate with no associated serious sequelae, this is believed to be a satisfactory method of therapy for women with squamous cell carcinoma in situ of the vagina occurring after pelvic irradiation.« less

This study aimed to explore the added value of histogram analysis of the ratio of initial to final 90-second time-signal intensity AUC (AUCR) for differentiating local tumor recurrence from contrast-enhancing scar on follow-up dynamic contrast-enhanced T1-weighted perfusion MRI of patients treated for head and neck squamous cell carcinoma (HNSCC). AUCR histogram parameters were assessed among tumor recurrence (n = 19) and contrast-enhancing scar (n = 27) at primary sites and compared using the t test. ROC analysis was used to determine the best differentiating parameters. The added value of AUCR histogram parameters was assessed when they were added to inconclusive conventional MRI results. Histogram analysis showed statistically significant differences in the 50th, 75th, and 90th percentiles of the AUCR values between the two groups (p < 0.05). The 90th percentile of the AUCR values (AUCR 90 ) was the best predictor of local tumor recurrence (AUC, 0.77; 95% CI, 0.64-0.91) with an estimated cutoff of 1.02. AUCR 90 increased sensitivity by 11.7% over that of conventional MRI alone when added to inconclusive results. Histogram analysis of AUCR can improve the diagnostic yield for local tumor recurrence during surveillance after treatment for HNSCC.

Eighty-six (60%) had T1 to T2 N0 and 57 (40%) had T1 to T2 N1 disease. Sixty-five patients (45%) underwent a robotic-assisted resection, whereas the remaining had transoral (n = 60; 42%), mandible-splitting (n = 11; 8%), or transhyoid approaches (n = 7; 5%). Human papillomavirus (HPV) status was known for 97 patients (68%), and 54 (55%) were HPV positive. Three-year recurrence-free survival (RFS) was 82% (95% confidence interval [CI] = 0.75-0.89). Since 2008, HPV infection was protective of recurrence (log-rank p = .0334). A single node did not increase the risk of recurrence (p = .467) or chance of a second primary (p = .175). Complete surgical resection is effective therapy for early and intermediate oropharyngeal SCC. HPV-negative patients were at increased risk for locoregional recurrence or second primary disease. © 2016 Wiley Periodicals, Inc. Head Neck 38: First-1471, 2016. © 2016 Wiley Periodicals, Inc.

Clinicopathological parameters, recurrence, locoregional and distant metastasis in 115 T1-T2 oral squamous cell carcinoma patients

PubMed Central

2010-01-01

The incidence of oral squamous cell carcinoma remains high. Oral and oro-pharyngeal carcinomas are the sixth most common cancer in the world. Several clinicopathological parameters have been implicated in prognosis, recurrence and survival, following oral squamous cell carcinoma. In this retrospective analysis, clinicopathological parameters of 115 T1/T2 OSCC were studied and compared to recurrence and death from tumour-related causes. The study protocol was approved by the Joint UCL/UCLH committees of the ethics for human research. The patients' data was entered onto proformas, which were validated and checked by interval sampling. The fields included a range of clinical, operative and histopathological variables related to the status of the surgical margins. Data collection also included recurrence, cause of death, date of death and last clinic review. Causes of death were collated in 4 categories (1) death from locoregional spread, (2) death from distant metastasis, (3) death from bronchopulmonary pneumonia, and (4) death from any non-tumour event that lead to cardiorespiratory failure. The patients' population comprised 65 males and 50 females. Their mean age at the 1st diagnosis of OSCC was 61.7 years. Two-thirds of the patients were Caucasians. Primary sites were mainly identified in the tongue, floor of mouth (FOM), buccal mucosa and alveolus. Most of the identified OSCCs were low-risk (T1N0 and T2N0). All patients underwent primary resection ± neck dissection and reconstruction when necessary. Twenty-two patients needed adjuvant radiotherapy. Pathological analysis revealed that half of the patients had moderately differentiated OSCC. pTNM slightly differed from the cTNM and showed that 70.4% of the patients had low-risk OSCC. Tumour clearance was ultimately achieved in 107 patients. Follow-up resulted in a 3-year survival of 74.8% and a 5-year survival of 72.2%. Recurrence was identified in 23 males and 20 females. The mean age of 1st diagnosis of the recurrence group was 59.53 years. Most common oral sites included the lateral border of tongue and floor of mouth. Recurrence was associated with clinical N-stage disease. The surgical margins in this group was evaluated and found that 17 had non-cohesive invasion, 30 had dysplasia at margin, 21 had vascular invasion, 9 had nerve invasion and 3 had bony invasion. Severe dysplasia was present in 37 patients. Tumour clearance was achieved in only 8 patients. The mean depth of tumour invasion in the recurrence group was 7.6 mm. An interesting finding was that 5/11 patients who died of distant metastasis had their primary disease in the tongue. Nodal disease comparison showed that 8/10 patients who died of locoregional metastasis and 8/11 patients who died from distant metastasis had clinical nodal involvement. Comparing this to pathological nodal disease (pTNM) showed that 10/10 patients and 10/11 patients who died from locoregional and distant metastasis, respectively, had nodal disease. All patients who died from locoregional and distant metastasis were shown to have recurrence after the primary tumour resection. Squamous cell carcinoma of the oral cavity has a poor overall prognosis with a high tendency to recur at the primary site and extend to involve the cervical lymph nodes. Several clinicopathological parameters can be employed to assess outcome, recurrence and overall survival. PMID:20406474

Squamous cell carcinoma (SCC) is an uncommon histologic subtype of bladder cancer with limited data on treatment patterns, outcomes, and prognostic factors. "Real world" information might inform decision-making, prognostic estimates, and clinical trial designs. A retrospective review of patients with tissue-confirmed bladder SCC treated at Cleveland Clinic from 2007 to 2016 was performed. Data on patient characteristics, treatment patterns, and clinical follow-up were extracted. Univariate analysis was used to identify predictors of overall survival (OS), recurrence-free survival (RFS) and time to recurrence. Of 58 identified patients, 42 had complete data available. Median age at diagnosis was 67 years (range, 37-90). Hematuria was the most common (71%) presenting symptom; 32 patients had pure SCC and 10 predominant/extensive squamous differentiation without major differences noted in clinicopathologic variables or outcomes among those 2 groups. Overall, 35 patients underwent cystectomy with 5 receiving neoadjuvant and 1 adjuvant chemotherapy, whereas 3 had chemotherapy for recurrent disease. Of patients with cystectomy, most had locally advanced disease (75% pT3/4, 35% pN+). Overall, 10 patients progressed and 14 died; median OS was not reached. The 2-year estimated OS, RFS, and cumulative incidence of recurrence were 61% ± 9%, 50% ± 9%, and 32% ± 9%, respectively. Hydronephrosis, older age (70 years or older), lymphovascular invasion, nodal metastases, and advanced T stage were associated with 1 or more poor outcomes. In patients with resectable bladder SCC, radical cystectomy remains the main treatment modality. The role of perioperative chemotherapy remains unclear. The identified prognostic factors might be helpful for prognostication, treatment discussion, and trial eligibility/stratification. Copyright © 2017 Elsevier Inc. All rights reserved.

(i) To report the successful treatment of 10 cases of equine periocular squamous cell carcinoma (PSCC) with surgical excision and photodynamic therapy (PDT) using verteporfin. (ii) To evaluate time to first tumor recurrence between PDT-treated horses and horses treated with surgical excision and cryotherapy. A total of 24 equine PSCC cases were included: group 1 (n = 14) had excision and cryotherapy (1993–2003), group 2 (n = 10), excision and local PDT (2006–2010). Evaluated data: signalment, treatment method, tumor location, size, and time to first recurrence. Groups were compared via chi-square test for categorical variables and Wilcoxon rank-sum test for numeric variables. Time to tumor recurrence was examined using Kaplan–Meier product-limit survival analysis. Of 24 cases, nine breeds were affected. Mean age at treatment in years: 14 (range 5–24) in group 1; 11 (range 8–18) in group 2. Median tumor size: 163 mm2 (range 20–625 mm2) in group 1; 195 mm2 (range 45–775 mm2) in group 2. Signalment, tumor laterality, and size were not significantly different between groups. Time to recurrence was significantly different between groups (Logrank test, P = 0.0006). In group 1, 11/14 horses had tumor regrowth with median time to recurrence in months: 10 (range 1–44). In group 2 (minimum follow-up of 25 months; range 25–50), no horse demonstrated tumor recurrence after one treatment with excision and PDT. This represents the first report of local PDT using verteporfin for treatment of equine PSCC. Following surgery, the likelihood of tumor recurrence was significantly reduced with local PDT compared with cryotherapy. © 2013 American College of Veterinary Ophthalmologists.

Evaluating patients for recurrent anal cancer after primary treatment can be difficult owing to distorted anatomy and scarring. Many institutions incorporate endoscopic ultrasound to improve detection, but the effectiveness is unknown. The aim of this study is to compare the effectiveness of digital rectal examination and endoscopic ultrasound in detecting locally recurrent disease during routine follow-up of patients with anal cancer. This study is a retrospective, single-institution review. This study was conducted at an oncologic tertiary referral center. Included were 175 patients with nonmetastatic anal squamous-cell cancer, without persistent disease after primary chemoradiotherapy, who had at least 1 posttreatment ultrasound and examination by a colorectal surgeon. The primary outcomes measured were the first modality to detect local recurrence, concordance, crude cancer detection rate, sensitivity, specificity, and predictive value. Eight hundred fifty-five endoscopic ultrasounds and 873 digital rectal examinations were performed during 35 months median follow-up. Overall, ultrasound detected 7 (0.8%) mesorectal and 32 (3.7%) anal canal abnormalities; digital examination detected 69 (7.9%) anal canal abnormalities. Locally recurrent disease was found on biopsy in 8 patients, all detected first or only with digital examination. Four patients did not have an ultrasound at the time of diagnosis of recurrence. The concordance of ultrasound and digital examination in detecting recurrent disease was fair at 0.37 (SE, 0.08; 95% CI, 0.21-0.54), and there was no difference in crude cancer detection rate, sensitivity, specificity, and negative or positive predictive values. The heterogeneity of follow-up timing and examinations is not standardized in this study but is reflective of general practice. Endoscopic ultrasound did not provide any advantage over digital rectal examination in identifying locally recurrent anal cancer, and should not be recommended for routine surveillance.

Purpose: To model locoregional recurrences of oropharyngeal squamous cell carcinomas (OSCC) treated with primary intensity modulated radiation therapy (IMRT) in order to find the origins from which recurrences grow and relate their location to original target volume borders. Methods and Materials: This was a retrospective analysis of OSCC treated with primary IMRT between January 2002 and December 2009. Locoregional recurrence volumes were delineated on diagnostic scans and coregistered rigidly with treatment planning computed tomography scans. Each recurrence was analyzed with two methods. First, overlapping volumes of a recurrence and original target were measured ('volumetric approach') and assessed as 'in-field', 'marginal',more » or 'out-field'. Then, the center of mass (COM) of a recurrence volume was assumed as the origin from where a recurrence expanded, the COM location was compared with original target volume borders and assessed as 'in-field', 'marginal', or 'out-field'. Results: One hundred thirty-one OSCC were assessed. For all patients alive at the end of follow-up, the mean follow-up time was 40 months (range, 12-83 months); 2 patients were lost to follow-up. The locoregional recurrence rate was 27%. Of all recurrences, 51% were local, 23% were regional, and 26% had both local and regional recurrences. Of all recurrences, 74% had imaging available for assessment. Regarding volumetric analysis of local recurrences, 15% were in-field gross tumor volume (GTV), and 65% were in-field clinical tumor volume (CTV). Using the COM approach, we found that 70% of local recurrences were in-field GTV and 90% were in-field CTV. Of the regional recurrences, 25% were volumetrically in-field GTV, and using the COM approach, we found 54% were in-field GTV. The COM of local out-field CTV recurrences were maximally 16 mm outside CTV borders, whereas for regional recurrences, this was 17 mm. Conclusions: The COM model is practical and specific for recurrence assessment. Most recurrences originated in the GTV. This suggests radioresistance in certain tumor parts.« less

BACKGROUND. Recurrence and/or metastasis occurs in more than half of patients with head and neck squamous cell carcinoma (HNSCC), and these events pose the greatest threats to long-term survival. We set out to identify genetic alterations that underlie recurrent/metastatic HNSCC. METHODS. Whole-exome sequencing (WES) was performed on genomic DNA extracted from fresh-frozen whole blood and patient-matched tumor pairs from 13 HNSCC patients with synchronous lymph node metastases and 10 patients with metachronous recurrent tumors. Mutational concordance within and between tumor pairs was used to analyze the spatiotemporal evolution of HNSCC in individual patients and to identify potential therapeutic targets for functional evaluation. RESULTS. Approximately 86% and 60% of single somatic nucleotide variants (SSNVs) identified in synchronous nodal metastases and metachronous recurrent tumors, respectively, were transmitted from the primary index tumor. Genes that were mutated in more than one metastatic or recurrent tumor, but not in the respective primary tumors, include C17orf104, inositol 1,4,5-trisphosphate receptor, type 3 (ITPR3), and discoidin domain receptor tyrosine kinase 2 (DDR2). Select DDR2 mutations have been shown to confer enhanced sensitivity to SRC-family kinase (SFK) inhibitors in other malignancies. Similarly, HNSCC cell lines harboring endogenous and engineered DDR2 mutations were more sensitive to the SFK inhibitor dasatinib than those with WT DDR2. CONCLUSION. In this WES study of patient-matched tumor pairs in HNSCC, we found synchronous lymph node metastases to be genetically more similar to their paired index primary tumors than metachronous recurrent tumors. This study outlines a compendium of somatic mutations in primary, metastatic, and/or recurrent HNSCC cancers, with potential implications for precision medicine approaches. FUNDING.

The purpose of this study was to identify the prevalence of cancer cachexia and its prognostic impact in patients with advanced head and neck squamous cell carcinoma (HNSCC). The prevalence of cancer cachexia was analyzed according to the follow-up periods during the first year after curative initial treatment. Recurrences, noncancer health events (NCHEs), and cause-specific survival outcomes were also analyzed according to the incidence of cancer cachexia during follow-up. Cancer cachexia was identified in 22 (6.1%), 148 (41%), 66 (18.4%), and 65 (18.7%) of 361 enrolled patients at pretreatment, immediately after treatment, 6-months after treatment, and 12-months after treatment, respectively. Sustained or newly developed cachexia at 6 and 12 months showed a significant association with recurrence and NCHE occurrence (p < .05). In cause-specific survival analysis, patients with cachexia had a higher probability of cancer-specific death, noncancerous death, and overall death (p < .05). Cachexia prevalence at 6 and 12 months after treatment for HNSCC indicates a higher chance of recurrence, NCHE, and death. © 2016 Wiley Periodicals, Inc.

The transcription factor SOX2 is an essential regulator of pluripotent stem cells and promotes development and maintenance of squamous epithelia. We previously reported that SOX2 is an oncogene and subject to highly recurrent genomic amplification in squamous cell carcinomas (SCCs). Here, we have further characterized the function of SOX2 in SCC. Using ChIP-seq analysis, we compared SOX2-regulated gene profiles in multiple SCC cell lines to ES cell profiles and determined that SOX2 binds to distinct genomic loci in SCCs. In SCCs, SOX2 preferentially interacts with the transcription factor p63, as opposed to the transcription factor OCT4, which is the preferred SOX2 binding partner in ES cells. SOX2 and p63 exhibited overlapping genomic occupancy at a large number of loci in SCCs; however, coordinate binding of SOX2 and p63 was absent in ES cells. We further demonstrated that SOX2 and p63 jointly regulate gene expression, including the oncogene ETV4, which was essential for SOX2-amplified SCC cell survival. Together, these findings demonstrate that the action of SOX2 in SCC differs substantially from its role in pluripotency. The identification of the SCC-associated interaction between SOX2 and p63 will enable deeper characterization the downstream targets of this interaction in SCC and normal squamous epithelial physiology.

In this case study, we present an unusual case with squamous cell carcinoma originating from a giant condyloma acuminata completely surrounding the penis. A 57-year-old circumcised heterosexual male patient presented with a penile lesion existing for 20 years. Incisional biopsy revealed acanthosis of the squamous epithelium. The patient was operated on under spinal anaesthesia. The lesion was resected circumferentially with macroscopic clearance, resulting in complete degloving of the penile shaft. Neurovascular bundles were preserved. The penile skin was constructed with a split thickness skin graft. Histopathological analysis of the lesion revealed an invasive and well-differentiated squamous cell carcinoma arising on a condyloma, and the surgical margins were free from tumour. The patient was staged as G2 T1 N0 M0 and was followed for one year. He did not have any erectile dysfunction and could engage in intercourse. Pelvic tomographic and physical examination findings did not reveal any episode of recurrence or metastasis. When encountering patients with giant condyloma acuminata, it should not be forgotten that it may be accompanied by squamous cell carcinoma. In addition, tissue excision should be as extensive as possible while keeping in mind the importance of the function. This is the first case of a penile-degloving surgery for giant penile condyloma, supporting conservative and preserving penile surgery for such tumours.

Basaloid squamous cell carcinoma (BSCC) is a histologically distinctive variant of squamous cell carcinoma comprising basal cell carcinoma and squamous cell carcinoma. BSCC is aggressive and shows a poor prognosis because of frequent lymph node invasion and distant metastases. BSCC preferentially occurs in the cervix, thymus, and esophagus and is uncommonly found in the head and neck region. BSCC in the nasal cavity or paranasal sinus is particularly rare. Inverted papilloma is an uncommon, benign tumor with a propensity to be associated with malignancy; however, BSCC arising in an inverted papilloma has never been reported. Here we report a case of a 56-year-old woman with BSCC arising in an inverted papilloma in the nasal cavity. The woman was referred to our hospital for epistaxis, nasal congestion, and dysphagia. A tumor was observed to completely occupy the left nasal cavity. The biopsy specimen was histologically diagnosed as papilloma. Computed tomography demonstrated a tumor with heterogeneous contrast effect occupying the left nasal cavity; however, extra-nasal tract extension was not observed. We performed endoscopic excision of the tumor. Microscopic findings confirmed the diagnosis of BSCC arising from an inverted papilloma. No tumor recurrence has been observed for 13 months after surgery. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Purpose: Normal tissues tolerance limits the use of reirradiation for recurrent head-and-neck cancers (HNC). Stereotactic body radiotherapy (SBRT) could offer precise irradiation while sparing healthy tissues. Results of a feasibility study using SBRT with or without cetuximab are reported for reirradiation of recurrent primary HNC. Methods and Materials: Patients with inoperable recurrent, or new primary tumor, in a previously irradiated area were included. Reirradiation dose was 36 Gy in six fractions of 6 Gy to the 85% isodose line covering 95% of the planning target volume. Patients with squamous cell carcinoma received concomitant cetuximab. Results: Between June 2007 and Januarymore » 2010, 40 patients were prospectively treated for 43 lesions. Median age was 60 and median tumor size was 29 mm. Fifteen patients received concomitant cetuximab and 1 received concomitant cisplatin. Median follow-up was 25.6 months with 34 patients evaluable for tumor response. Median overall survival was 13.6 months and response rate was 79.4% (15 complete and 12 partial responses). Grade 3 toxicity occurred in 4 patients. Conclusion: These results suggest that short SBRT with or without cetuximab is an effective salvage treatment with good response rate in this poor prognosis population with previously irradiated HNC. Treatment is feasible and, with appropriate care to limiting critical structure, acute toxicities are acceptable. A prospective multicenter Phase II trial of SRT and concomitant cetuximab in recurrent HNC squamous cell carcinoma is ongoing.« less

Despite recent advances in radiochemotherapy, treatment of locally advanced head and neck squamous cell carcinoma is still challenging, and survival rates have improved only slightly. This is due to the high frequency of metastases and local and/or regional tumor recurrences that have acquired radio- or chemoresistance. MiRNAs regulate diverse processes in tumorigenesis, metastasis, and therapy resistance in head and neck squamous cell carcinoma. Hence, miRNAs are highly valued in biomarker studies. Establishment of the miRNA profiles of oropharyngeal tumors enables personalized treatment selection, since expression of distinct miRNAs can predict the response to two different radiochemotherapy regimens. Development of novel miRNA therapeutics has a high clinical potential for further improving treatment of cancerous disease. The use of nanoparticles with distinct surface modifications as miRNA vectors permits prolonged bioavailability, high efficacy in tumor targeting, and low toxicity. Nevertheless, the efficacy of miRNA therapy has only been shown in animal models to date.

Spontaneous remission is a rare, but well recognized event in oncology. Certain tumours, such as melanomas, hypernephromas and neuroblastomas, are known for showing spontaneous regression. Similarly, spontaneous regression of oral lymphomas, as well as oropharyngeal and recurrent tongue carcinomas, has been reported. Here, we present a novel case of a patient with a primary squamous cell carcinoma on the floor of the mouth whose tumour regressed spontaneously in three months, without any treatment. We also review of the literature on the spontaneous remission of oral cancer and discuss possible mechanisms for this phenomenon.

Recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN) has a poor prognosis and the combination of cisplatin and cetuximab, with or without 5-fluorouracil, is the gold standard treatment in this stage. Thus, the concomitant use of novel compounds represents a critical strategy to improve treatment results. Histone deacetylase inhibitors (HDACi) enhance the activity of several anticancer drugs including cisplatin and anti-Epidermal Growth Factor Receptor (anti-EGFR) compounds. Preclinical studies in models have shown that vorinostat is able to down regulate Epidermal Growth Factor Receptor (EGFR) expression and to revert epithelial to mesenchimal transition (EMT). Due to its histone deacetylase (HDAC) inhibiting activity and its safe use as a chronic therapy for epileptic disorders, valproic acid (VPA) has been considered a good candidate for anticancer therapy. A reasonable option may be to employ the combination of cisplatin, cetuximab and VPA in recurrent/metastatic SCCHN taking advantage of the possible positive interaction between histone deacetylase inhibitors, cisplatin and/or anti-EGFR. V-CHANCE is a phase 2 clinical trial evaluating, in patients with recurrent/metastatic squamous cell carcinoma of the head and neck never treated with first-line chemotherapy, the concomitant standard administration of cisplatin (on day 1, every 3 weeks) and cetuximab (on day 1, weekly), in combination with oral VPA given daily from day -14 with a titration strategy in each patient (target serum level of 50-100 μg/ml). Primary end point is the objective response rate measured according to Response Evaluation Criteria in Solid Tumors (RECIST). Sample size, calculated according to Simon 2 stage minimax design will include 21 patients in the first stage with upper limit for rejection being 8 responses, and 39 patients in the second stage, with upper limit for rejection being 18 responses. Secondary endpoints are time to progression, duration of response, overall survival, safety. Objectives of the translational study are the evaluation on tumor samples of markers of treatment efficacy/resistance (i.e. γH2AX, p21/WAF, RAD51, XRCC1, EGFR, p-EGFR, Ki-67) and specific markers of VPA HDAC inhibitory activity (histones and proteins acetylation, Histone deacetylase isoforms) as well as valproate test, histones and proteins acetylation of peripheral blood mononuclear cell, tested on blood samples at baseline and at different time points during treatment. Overall, this study could provide a less toxic and more effective first-line chemotherapy regimen in patients with recurrent/metastatic squamous cell carcinoma of the head and neck by demonstrating the feasibility and efficacy of cisplatin/cetuximab plus valproic acid. Moreover, correlative studies could help to identify responder patients, and will add insights in the mechanism of the synergistic interaction between these agents. 2014-001523-69 TRIAL REGISTRATION: ClinicalTrials.gov number, NCT02624128.

The potential of Mitomycin C in combination with fractionated irradiation to inhibit tumour cell repopulation of a fast growing squamous cell carcinoma after fractionated radiotherapy was investigated in vivo. A rapidly growing human squamous cell carcinoma (FaDudd) was used for the study. For experiments, NMRI (nu/nu) mice with subcutaneously growing tumours were randomly allocated to no treatment, Mitomycin C, fractionated irradiation (ambient: 11x4.5 Gy in 15 days), or fractionated irradiation combined with Mitomycin C. Graded top up doses (clamped blood flow: 0–57 Gy) were given at day 16, 23, 30 or 37. End point of the study was the time to local tumour progression. Data were examined by multiple regression analysis (Cox). Mitomycin C alone resulted in a median time to local tumour progression of 23 (95% confidence limits: 17–43) days, fractionated irradiation in 31 (25–35) days and combined Mitomycin C plus fractionated irradiation in 65 (58–73) days (P=0.02). Mitomycin C decreased the relative risk of local recurrence by 94% (P<<0.001) equivalent to 31.7 Gy top up dose. Repopulation accounted for 1.33 (0.95–1.72) Gy per day top up dose after fractionated irradiation alone and for 0.68 (0.13–1.22) Gy per day after fractionated irradiation+Mitomycin C (P=0.018). Mitomycin C significantly reduces the risk of local recurrence and inhibits tumour cell repopulation in combination with fractionated irradiation in vivo in the tested tumour model.

To determine the frequency of driver mutations in Chinese non-small cell lung cancer (NSCLC) patients. Comprehensive mutational analysis was performed in 1356 lung adenocarcinoma, 503 squamous cell carcinoma, 57 adenosquamous lung carcinoma, 19 large cell carcinoma and 8 sarcomatoid carcinoma. The effect of EGFR tyrosine kinase inhibitors (TKIs) on EGFR-mutated lung adenocarcinoma patients after disease recurrence was investigated. Mutations in EGFR kinase domain, HER2 kinase domain, KRAS, BRAF, ALK, ROS1 and RET were mutually exclusive. In lung adenocarcinoma cases "pan-negative" for the seven above-mentioned driver mutations, we also detected two oncogenic EGFR extracellular domain mutations (A289D and R324L), two HER2 extracellular and transmembrane domain mutations (S310Y and V659E), one ARAF S214C mutation and two CD74-NRG1 fusions. Six (1.2%) FGFR3 activating mutations were identified in lung squamous cell carcinoma (five S249C and one R248C). There were three (15.8%) EGFR mutations and four (21.1%) KRAS mutations in large cell carcinoma. Three (37.5%) KRAS mutations were detected in sarcomatoid carcinoma. In EGFR-mutated lung adenocarcinoma patients who experienced disease recurrence, treatment with EGFR TKIs was an independent predictor of better overall survival (HR = 0.299, 95% CI: 0.172-0.519, P < 0.001). We determined the frequency of driver mutations in a large series of Chinese NSCLC patients. EGFR TKIs might improve the survival outcomes of EGFR-mutated lung adenocarcinoma patients who experienced disease recurrence.

Relapse and metastasis are the main causes of unfavorable outcome in head and neck cancers. Whereas, understanding of the molecular background of these processes is far from being complete. Therefore, in this study we aimed to identify potential biomarker candidates of relapse and metastasis in laryngeal squamous cell carcinoma (LSCC) by combining the 2D electrophoresis based protein screen and immunohistochemical analysis of candidate proteins. We screened three groups of LSCC cell lines derived from primary tumors, recurrent tumors and metastases and identified seven proteins that differed significantly in relative abundance between the analyzed groups. Among the identified proteins were the heat shock proteins HSP60 and HSP70 that were significantly downregulated both in recurrences- and metastases-derived cell lines but not in primary tumor-derived cell lines. Moreover, we identified significant upregulation of the annexin V, calreticulin and the inorganic pyrophosphatase (PPA1) exclusively in the metastases-derived cell lines. As these upregulated proteins could potentially become novel biomarkers of metastasis, we have compared their abundance in primary tumor LSCC N(0) cases, primary tumor LSCC N(+) cases as well as in LSCC metastases N(+). Our results show an intense increase of cytoplasmic PPA1 abundance in the N(+) (p = 0.000042) compared to the N(0) group. In summary, we show a group of proteins deregulated in recurrences and metastases of LSCC. Moreover, we suggest the PPA1 protein as a potential new biomarker for metastasis in this cancer.

The patient was a 68-year-old man who complained of hoarseness and dyspnea. Upper gastrointestinal endoscopy revealed a type 3 tumor located in the middle thoracic esophagus at 30 cm from the incisor tooth that involved one-fourth of the circumference of the esophagus. Histopathological examination revealed moderately differentiated squamous cell carcinoma. Chest computed tomography( CT) revealed severe tracheal stenosis due to compression by a metastatic lymph node along the left recurrent laryngeal nerve. The patient was diagnosed as having cT4( 106recL-trachea), N2( 101L, 106recL, 106recR), M0, Stage IVa unresectable esophageal carcinoma. After insertion of a tracheal stent tube( spiral Z stent: diameter, 18 mm; length, 80 mm) to improve dyspnea, combination chemotherapy with 5-fluorouracil( 5-FU) plus nedaplatin was administered. Subsequent CT and endoscopy showed that the main tumor and the metastatic lymph node had significantly reduced in size and that complete response (CR) had been achieved. Thirty months after the initial treatment, the patient showed no sign of disease recurrence, after completion of 19 cycles of chemotherapy. The patient did not experience any severe adverse events. We report a case of a patient with locally advanced squamous cell carcinoma of the esophagus successfully treated with 5-FU/nedaplatin combination chemotherapy following tracheal stent tube placement.

The gold standard for the management of laryngeal squamous cell carcinoma in a previously irradiated patient is "salvage" total laryngectomy, but surgical management by partial laryngectomy can sometimes be proposed in selected patients. This study was designed to review the functional and oncological outcomes of patients treated by open partial laryngectomy for recurrent squamous cell carcinoma after failure of radiotherapy or involving previously irradiated tissues and to define prognostic criteria for the selection of patients eligible for this treatment strategy. In this retrospective study, 20 patients underwent partial laryngectomy between 2000 and 2011 for recurrence or second primary stage I or II laryngeal squamous cell carcinoma in an irradiated territory (11 vertical partial laryngectomies; 9 horizontal partial laryngectomies). The 3-year overall survival rate in patients with negative resection margins was 66%, with higher survival rates for tumours confined to the glottis, and the 2-year local control rate was 67%. Positive resection margins requiring total laryngectomy were observed in 20% of cases. The 3-year overall survival rate was 56% in these patients. Exclusive oral feeding was restored in 75% of patients after an average of 32 days. The tracheotomy tube was removed after an average of 18 days in 90% of patients. The disease-free functional larynx preservation rate was 45%. Salvage partial laryngectomy in irradiated tissues is an alternative treatment option to total laryngectomy in selected patients.

The aim of this study was to determine the outcome of salvage definitive chemoradiation (dCRT) for a locoregional recurrence after any prior curative treatment outside previously irradiated areas. Thirty-nine patients treated between January 2005 and December 2014 were reviewed for locoregional recurrent esophageal cancer outside previously irradiated areas. All patients received salvage treatment with external beam radiotherapy (50.4 Gy in 28 fractions) combined with weekly concurrent paclitaxel and carboplatin. The median follow-up period was 15 months (range 1.7-120). The median overall survival (OS) for all patients after salvage dCRT was 22 months (95% CI 6.2-37.6). The 1-, 3-, and 5-year OS was 72%, 31%, and 28%, respectively. Median survival after salvage dCRT for a regional lymph node recurrence was 33 months (95% CI 5.8-60.3) versus 14 months (95% CI 6.8-21.6) for a recurrence at the anastomosis (P = 0.022, logrank). Median OS was 35 months for the squamous cell carcinoma group and 19 months for the adenocarcinoma group (P = 0.67). Sixteen of 39 patients developed a locoregional recurrence after salvaged dCRT. The median locoregional recurrence-free survival (LRFS) was 24 months. The 1-, 3-, and 5-year LRFS was 79%, 36%, and 36%, respectively. Median disease-free survival (DFS) was 15 months. The 1-, 3-, and 5-year DFS was 66%, 27%, and 27%, respectively. Of 16 patients, 8 (50%) with a primary failure at the site of the anastomosis developed a local recurrence after salvaged dCRT compared to 7 of 22 patients (32%) with a primary recurrence in a lymph node. Definitive chemoradiation is a feasible and effective treatment for locoregional recurrent esophageal cancer outside a previously irradiated area, and should be given with a curative intent. This holds true for recurrence of both squamous cell carcinoma and adenocarcinoma. Lymph node recurrences have a markedly better prognosis than recurrences at the site of the anastomosis. © 2016 International Society for Diseases of the Esophagus.

Objective: To investigate the value of planned neck dissection combined with induction chemotherapy and concurrent chemoradiotherapy in regional control and the outcome of locally advanced head and neck squamous cell carcinoma. Methods: A prospective randomized controlled study totally enrolled sixty-four patients of head and neck squamous cell carcinomas(include oropharynx, hypopharynx, and larynx) in stages Ⅳa-Ⅳb with lymph node metastase was were N2-N3. All patients firstly received 2-3 cycles of induction chemotherapy(ICT), then divided into two groups randomly, according to the efficacy of ICT. Group A(the study group) received planned neck dissection(PND) and concurrent chemoradiotherapy(CCRT). Group B(the control group) received concurrent chemoradiotherapy(CCRT). The differences in clinicopathologic features, local recurrence(LR), regional recurrence(RR), disease-free survival(DFS), and overall survival(OS) between the two groups were estimated. SPSS 19.0 software was used to analyze the data. Results: Group A enrolled twenty-one patients, and group B enrolled forty-three patients.The follow-up of all patients were 4-55 months, median follow-up time was 22 months. In study group, two-year OS and DFS were 80.9% and 68.3%, respectively. In control group, two-year OS and DFS were 90.7% and 67.1%, respectively. There was no significant difference in gender( P =0.215), age( P =0.828), primary tumor site( P =0.927), LR( P =0.126), DFS( P =0.710), and OS( P =0.402) between the two groups, while the RR(χ(2)=5.640, P <0.05) and distant metastasis(χ(2)=10.363, P <0.01) showed significant differences between the two groups. Conclusion: The ICT+ PND+ CCRT treatment model has benefit on regional control of locally advanced head and neck squamous cell carcinoma.

Purpose: To provide a comprehensive risk assessment on the patterns of recurrence in electively irradiated lymph node regions after definitive radiation therapy for head and neck cancer. Methods and Materials: Two hundred sixty-four patients with stage cT2-4N0-2M0 squamous cell carcinoma of the oropharynx, larynx, or hypopharynx treated with accelerated intensity modulated radiation therapy between 2008 and 2012 were included. On the radiation therapy planning computed tomography (CT) scans from all patients, 1166 lymph nodes (short-axis diameter ≥5 mm) localized in the elective volume were identified and delineated. The exact sites of regional recurrences were reconstructed and projected on the initial radiationmore » therapy planning CT scan by performing coregistration with diagnostic imaging of the recurrence. Results: The actuarial rate of recurrence in electively irradiated lymph node regions at 2 years was 5.1% (95% confidence interval 2.4%-7.8%). Volumetric analysis showed an increased risk of recurrence with increasing nodal volume. Receiver operating characteristic analysis demonstrated that the summed long- and short-axis diameter is a good alternative for laborious volume calculations, using ≥17 mm as cut-off (hazard ratio 17.8; 95% confidence interval 5.7-55.1; P<.001). Conclusions: An important risk factor was identified that can help clinicians in the pretreatment risk assessment of borderline-sized lymph nodes. Not overtly pathologic nodes with a summed diameter ≥17 mm may require a higher than elective radiation therapy dose. For low-risk elective regions (all nodes <17 mm), the safety of dose de-escalation below the traditional 45 to 50 Gy should be investigated.« less

Transoral laser microsurgery (TLM) has been increasingly used in lieu of total laryngectomy to treat malignancy after definitive radiation. There are few data in the literature regarding functional outcomes. We retrospectively reviewed voice and swallowing outcomes in patients who underwent TLM for recurrent laryngeal carcinoma. Case series with chart review. Tertiary care center. Forty-two patients were identified with recurrent squamous cell carcinoma of the larynx after definitive radiation therapy from 2001 to 2013: 28 patients with glottic recurrence and 14 with supraglottic recurrence. Swallowing outcomes were evaluated by gastrostomy tube dependence, the MD Anderson Dysphagia Inventory, and the Functional Oral Intake Scale. Voice outcomes were evaluated by the Voice Handicap Index and observer-rated perceptual analysis. No significant difference was noted between mean pre- and postoperative MD Anderson Dysphagia Inventory scores: 78.25 and 74.9, respectively (P = .118, t = 1.6955). Mean Functional Oral Intake Scale scores after TLM for supraglottic and glottic recurrences were 6.4 and 6.6, respectively. Of 42 patients, 17 (40.5%) required a gastrostomy tube either during radiation or in conjunction with the salvage procedure. Of 17 patients, 15 resumed sufficient oral diet for tube removal. Patients' mean Voice Handicap Index score did increase from 34.3 to 51.5 (P = .047), and their mean perceptual score did decrease from 60.0 to 45.3 (P = .005). However, at 1-year follow-up, there was no significant difference in perceptual score: 61.1 to 57.1 (P = .722). TLM is a successful surgical option for recurrent laryngeal cancer with acceptable functional outcomes. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Purpose: Reirradiation (re-RT) of recurrent head and neck cancer (HNC) may achieve long-term disease control in some patients, at the expense of high rates of late sequelae. Limiting the re-RT targets to the recurrent gross tumor volume (rGTV) would reduce the volumes of reirradiated tissues; however, its effect on tumor recurrence pattern is unknown. Methods and Materials: This is a retrospective review of 66 patients who underwent curative-intent re-RT for nonresectable recurrent or second primary mucosal squamous cell HNC. Treatment was delivered with three-dimensional conformal (3D) RT or intensity-modulated RT (IMRT). The targets in all patients consisted of the rGTVsmore » with tight (0.5-cm) margins, with no intent to treat prophylactically lymph nodes or subclinical disease in the vicinity of the rGTVs. The sites of locoregional failures (LRFs) were determined using imaging at the time of failure and were compared with the rGTVs. Results: Median re-RT dose was 68 Gy. Forty-seven patients (71%) received concomitant chemotherapy, and 31 (47%) received hyperfractionated, accelerated RT. At a median follow-up of 42 months, 16 (23%) were alive and disease-free. Fifty patients (77%) had a third recurrence or persistent disease, including 47 LRFs. All LRFs occurred within the rGTVs except for two (4%) (95% confidence interval, 0-11%). Nineteen patients (29%) had Grade {>=} 3 late complications, mostly dysphagia (12 patients). Conclusions: Almost all LRFs occurred within the reirradiated rGTVs despite avoiding prophylactic RT of tissue at risk of subclinical disease. These results support confining the re-RT targets to the rGTVs to reduce reirradiated tissue volumes.« less

The recurrence and progression of brain metastases after brain irradiation are a major cause of mortality and morbidity in patients with cancer. The risk of radiation-induced neurotoxicity and efficacy probably leads oncologists to not consider re-irradiation. We report the case of a 48-year-old Asian male diagnosed with squamous cell lung cancer and multiple brain metastases initially treated with 40 Gy whole-brain radiotherapy and 20 Gy partial brain boost. Fourteen gray stereotactic radiosurgery as salvage for brain metastases in the left occipital lobe was performed after initial irradiation. The recurrence of brain metastases in the left occipital lobe was demonstrated on magnetic resonance imaging at 9 months after initial radiotherapy. He received the second course of 28 Gy stereotactic radiosurgery for the recurrent brain metastases in the left occipital lobe. The third relapse of brain metastases was demonstrated by a magnetic resonance imaging scan at 7 months after the second radiotherapy. The third course of irradiation was performed because he refused to undergo surgical resection of the recurrent brain metastases. The third course of irradiation used a pulsed reduced dose-rate radiotherapy technique. It was delivered in a series of 0.2 Gy pulses separated by 3-min intervals. The recurrent brain metastases were treated with a dose of 60 Gy using 30 daily fractions of 2 Gy. Despite the brain metastases receiving 162 Gy irradiation, this patient had no apparent acute or late neurologic toxicities and showed clinical improvement. This is the first report of the pulsed reduced dose-rate radiotherapy technique being used as the third course of radiotherapy for recurrent brain metastases.

This study explores the safety and efficacy of strontium 90 (Sr-90) brachytherapy as the sole adjuvant therapy for carcinoma in situ (CIS) and squamous cell carcinoma (SCC) of the conjunctiva in a high HIV prevalent area. This is a retrospective case review of patients treated with 60 Gray Sr-90 brachytherapy in four divided doses after resection with a 2 mm margin and histological confirmation. Cryotherapy or alcohol debridement was not performed at the time of excision due to limited resources. Two plaque sizes, 8.5 mm and 18 mm, were used. Sixty-nine patients were treated and had a median follow-up of 27 months (range 6-127). Thirty-three (47.8%) were HIV-positive. CIS was present in 40.6% and SCC in 59.4%. The surgical margins were positive in 39 (56.5%). Twenty patients (29.0%) were treated with the 18 mm plaque and 49 (71.0%) with the 8.5 mm plaque. Eight (11.6%) patients developed a recurrence at a median of 5 months (range 2-40). Recurrences only occurred in patients treated with the 8.5 mm plaque (p=0.094). There was no significant effect of HIV status, positive margins or staging on the number of recurrences. Treatment side effects were a dry eye in five patients which was successfully managed with topical lubricants, and induced astigmatism of 1 dioptre of cylinder in one patient. Sr-90 brachytherapy is safe and effective in preventing recurrences in ocular surface squamous neoplasia in a high HIV prevalent setting. The 18 mm plaque size is superior to the 8.5 mm plaque size.

Photodynamic therapy and the treatment of neoplastic diseases of the larynx

NASA Astrophysics Data System (ADS)

Biel, Merrill A.

1995-05-01

Photodynamic therapy (PDT) is an innovative treatment involving the use of light-sensitive drugs to selectively identify and destroy diseased cells. Therefore, photodynamic therapy has the potential to treat and cure precancerous and early cancerous lesions (carcinoma in situ (CIS), T1 and T2) of the larynx while preserving normal tissue. Twenty-four patients with recurrent leukoplakia and carcinomas of the larynx were treated with PDT with follow-up to 60 months. Fourteen patients with T1 squamous cell carcinomas of the vocal cord, 2 patients with a T2 squamous cell carcinoma of the vocal cord failing radiotherapy, and 6 patients with CIS and sever atypia were treated with PDT and obtained a complete response and are disease free. One patient with a T3 carcinoma of the larynx was treated with PDT but died 5 weeks post-treatment of unrelated causes and could not be assessed. Photodynamic therapy is a promising therapy for treatment of precancerous and cancerous lesions of the larynx. This therapy may be particularly beneficial for the treatment of recurrent carcinomas of the larynx that have failed conventional radiotherapy, thereby preserving voice and eliminating the need for destructive laryngeal surgery.

Abstract On August 5, 2016, the U.S. Food and Drug Administration granted accelerated approval to pembrolizumab (KEYTRUDA injection, Merck Sharp & Dohme Corp., Kenilworth, NJ) for treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum‐containing chemotherapy. Approval was based on the objective response rate (ORR) and duration of response (DoR) in a cohort of patients in a nonrandomized multi‐cohort trial (KEYNOTE‐012) that included 174 patients with recurrent or metastatic HNSCC who had disease progression on or after platinum‐containing chemotherapy. Patients received either intravenous pembrolizumab 10 mg/kg every 2 weeks or 200 mg every 3 weeks. ORR was determined by independent review according to Response Evaluation Criteria in Solid Tumors 1.1. ORR was 16% (95% confidence interval 11, 22) with a complete response rate of 5%. DoR ranged from 2.4+ months to 27.7+ months. Twenty‐three of 28 responding patients (82%) had response durations of ≥6 months. Safety was evaluated in 192 patients with HNSCC receiving at least one dose of pembrolizumab. Frequent (≥2%) serious adverse reactions were pneumonia, dyspnea, confusional state, vomiting, pleural effusion, and respiratory failure. Clinically significant immune‐mediated adverse reactions included pneumonitis, colitis, hepatitis, adrenal insufficiency, diabetes mellitus, skin toxicity, myositis, and thyroid disorders. The benefit‐risk profile of pembrolizumab was considered acceptable in this patient population. As a condition of accelerated approval, Merck is required to conduct a confirmatory trial; this trial, KEYNOTE‐040, is ongoing. Implications for Practice. This accelerated approval expands the U.S. Food and Drug Administration‐approved indications for pembrolizumab, providing health care providers with new information regarding pembrolizumab for the treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum‐containing chemotherapy. Pembrolizumab is the first drug to receive approval for treatment of patients with HNSCC since cetuximab was approved for this indication in 2006. PMID:28533473

Oesophageal squamous cell carcinoma is a deadly disease where systemic therapy has relied upon empiric chemotherapy despite the presence of genomic alterations pointing to candidate therapeutic targets, including recurrent amplification of the gene encoding receptor tyrosine kinase epidermal growth factor receptor (EGFR). Here, we demonstrate that EGFR-targeting small-molecule inhibitors have efficacy in EGFR-amplified oesophageal squamous cell carcinoma (ESCC), but may become quickly ineffective. Resistance can occur following the emergence of epithelial-mesenchymal transition and by reactivation of the mitogen-activated protein kinase (MAPK) pathway following EGFR blockade. We demonstrate that blockade of this rebound activation with MEK (mitogen-activated protein kinase kinase) inhibition enhances EGFR inhibitor-induced apoptosis and cell cycle arrest, and delays resistance to EGFR monotherapy. Furthermore, genomic profiling shows that cell cycle regulators are altered in the majority of EGFR-amplified tumours and a combination of cyclin-dependent kinase 4/6 (CDK4/6) and EGFR inhibitors prevents the emergence of resistance in vitro and in vivo. These data suggest that upfront combination strategies targeting EGFR amplification, guided by adaptive pathway reactivation or by co-occurring genomic alterations, should be tested clinically.

Oral squamous cell carcinomas comprise a heterogeneous tumor cell population with varied molecular characteristics, which makes prognostication of these tumors a complex and challenging issue. Thus, molecular profiling of these tumors is advantageous for an accurate prognostication and treatment planning. This is a retrospective study on a cohort of primary locally advanced oral squamous cell carcinomas (n = 178) of an Indian rural population. The expression of EGFR, p53, cyclin D1, Bcl-2 and p16 in a cohort of primary locally advanced oral squamous cell carcinomas was evaluated. A potential biomarker that can predict the tumor response to treatment was identified. Formalin-fixed paraffin-embedded tumor blocks of (n = 178) of histopathologically diagnosed cases of locally advanced oral squamous cell carcinomas were selected. Tissue microarray blocks were constructed with 2 cores of 2 mm diameter from each tumor block. Four-micron-thick sections were cut from these tissue microarray blocks. These tissue microarray sections were immunohistochemically stained for EGFR, p53, Bcl-2, cyclin D1 and p16. In this cohort, EGFR was the most frequently expressed 150/178 (84%) biomarker of the cases. Kaplan-Meier analysis showed a significant association (p = 0.038) between expression of p53 and a poor prognosis. A Poisson regression analysis showed that tumors that expressed p53 had a two times greater chance of recurrence (unadjusted IRR-95% CI 2.08 (1.03, 4.5), adjusted IRR-2.29 (1.08, 4.8) compared with the tumors that did not express this biomarker. Molecular profiling of oral squamous cell carcinomas will enable us to categorize our patients into more realistic risk groups. With biologically guided tumor characterization, personalized treatment protocols can be designed for individual patients, which will improve the quality of life of these patients.

The purpose of this study was to evaluate the effectiveness of postoperative beta-irradiation with strontium-90 as an adjunctive treatment to superficial keratectomy and permanent bulbar conjunctival graft for removal of equine corneolimbal squamous cell carcinoma (SCC), in decreasing recurrence rate. The retrospective case study included 38 horses diagnosed and treated for SCC of the eye that involved the limbus and/or cornea. The patients were treated between 1990 and 2002, with strontium-90 irradiation immediately after corneal and conjunctival graft surgery. Recurrence was defined as the postoperative and postirradiation regrowth of SCC in the same site and globe that was previously treated. The Appaloosa was the most commonly represented breed and horses that had more than one base coat color represented the majority of the cases (53%). The coat colors of white, chestnut/sorrel and gray were the most commonly represented colors of the horses treated. Eight horses (21%) could not be assessed for tumor recurrence due to lack of two or more post-treatment examinations, and another horse was enucleated 6 days postoperatively due to progressive corneal ulceration. Twenty-four horses (63% of the entire study population; 83% of the followed cases) had a mean +/- SD of 1754 +/- 1319 days without tumor recurrence, ranging from 14 days to 5110 days. Five horses (13% of the entire study population; 17% of the assessed horses) had tumor recurrence at a mean +/- SD of 449 +/- 339 days with a range of 29 days to 900 days. For the five recurrences, treatment included local excision (n = 1), enucleation (n = 2), and additional strontium-90 therapy (n = 3). The combination of superficial keratectomy, beta-irradiation and permanent bulbar conjunctival grafts for limbal, corneal or corneolimbal SCC in horses is effective in at least 83% of the horses. Recurrence occurred in about 17% of the horses. Multiple biannual re-examinations are recommended to observe for tumor recurrence.

The prognosis of recurrent/metastatic (R/M) squamous cell carcinoma of the head and neck (HNSCC) after failure of first line chemotherapy is dismal. Until the publication of the results of CheckMate 141, not a single agent provided any survival benefit as a second line treatment for R/M HNSCC. Areas covered: A comprehensive review of the literature was conducted on the role of nivolumab in HNSCC. Expert commentary: Nivolumab is approved by the Food and Drug Administration for the treatment of patients based on the results of CheckMate 141 showing an overall survival benefit as compared to standard care (single agent docetaxel, methotrexate, or cetuximab). Of particular interest are immune-related adverse events which should be managed according to published guidelines.

We reviewed our series of anal squamous cell carcinomas (ASCC) treated over the last two decades. ASCC patients undergoing treatment at the Leicester Royal Infirmary between 1998 and 2016 were selected. Age, gender, pathological tumor characteristics, treatment adopted, the overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS) at 5-year follow-up were recorded and calculated. A total of 190 ASCC were reviewed, of these 64.2% (n = 122) received primary radical chemoradiotherapy. Complete response rate was 92.6% (n = 113) and four patients with residual disease underwent a salvage APER. Twenty-eight patients experienced recurrent disease (23.0%) either systemic (n = 8), local (n = 14), or both (n = 6); six had a salvage APER. Complete follow-up data are available for 63.1% patients (77/122). Overall, the locoregional failure rate of primary chemoradiotherapy (residual + recurrent disease) was present in 29 patients (29/122; 23.8%). OS was 41.6% CSS was 69.2% and DFS 60.0% at 5 years follow-up. In our series of ASCC primary chemoradiotherapy had achieved significant initial complete response rates, however, long term-follow ups still present systemic and local recurrences. APR is able to treat 30% of the pelvic recurrences (6/20), the others are either associated with systemic disease or locally inoperable masses. © 2017 Wiley Periodicals, Inc.

Superficial esophageal squamous cell carcinoma (ESCC) is generally considered a subtype of less invasive ESCC. Yet a subset of these superficial ESCC would have metastasis after esophagostomy or endoscopic resection and lead to poor prognosis. The objective of this study is to determine biomarkers that can identify such subset of superficial ESCC that would have metastasis after surgery using genome wide copy number alteration (CNA) analyses. The CNAs of 38 cases of superficial ESCCs originated from radical surgery, including 19 without metastasis and 19 with metastasis within 5 years' post-surgery, were analyzed using Affymetrix OncoScan™ FFPE Assay. A 39-gene signature was identified which characterized the subset of superficial ESCC with high risk of metastasis after surgery. In addition, recurrent CNAs of superficial ESCC were also investigated in the study. Amplification of 11q13.3 (FGF4) and deletion of 9p21.3 (CDKN2A) were found to be recurrent in all 38 superficial ESCCs analyzed. Notably amplifications of 3p26.33 (SOX2OT), 8q24.21 (MYC), 14q21.1 (FOXA1) and deletion of 3p12.1 (GBE1) were only found to be recurrent in metastaic superficial ESCCs. In conclusion, using CNAs analyses, we identify a 39-gene signature which characterizes the high risk metastatic superficial ESCCs and discover several recurrent CNAs that might be the driver alterations in metastasis among superficial ESCCs.

Oral cancer is a public health problem with high prevalence in the population. Local tumor control is best achieved by complete surgical resection with adequate margins. A disease-free surgical margin correlates with a lower rate of local recurrence and a higher rate of disease-free survival. Fluorescence spectroscopy is a noninvasive diagnostic tool that can aid in real-time cancer detection. The technique, which evaluates the biochemical composition and structure of tissue fluorescence, is relatively simple, fast and, accurate. This study aimed to compare oral squamous cell carcinoma lesions to surgical margins and the mucosa of healthy volunteers by fluorescence spectroscopy. The sample consisted of 56 individuals, 28 with oral squamous cell carcinoma and 28 healthy volunteers with normal oral mucosa. Thirty six cases (64.3%) were male and the mean age was 60.9 years old. The spectra were classified and compared to histopathology to determine fluorescence efficiency for diagnostic discrimination of tumors. In the analysis of the other cases we observed discrimination between normal mucosa, injury and margins. At two-year follow up, three individuals had local recurrence, and in two cases investigation fluorescence in the corresponding area showed qualitative differences in spectra between the recurrence area and the area without recurrence at the same anatomical site in the same patient. In situ analysis of oral mucosa showed the potential of fluorescence spectroscopy as a diagnostic tool that can aid in discrimination of altered mucosa and normal mucosa.

Common Head and Neck Cases in Our Consultation Referrals: Diagnostic Dilemmas in Inverted Papilloma

PubMed Central

2009-01-01

Papillomas of the nose and paranasal sinuses comprise three morphologically distinct variants—everted papilloma, inverted papilloma and cylindric cell papilloma in descending order of frequency. Recurrence of everted papilloma is unusual and malignant change does not occur. However, inverted papilloma is associated with multiple recurrences and malignant change. The histology of low grade squamous cell carcinoma of the nose may mimic that of inverted papilloma and low grade squamous cell carcinoma may coexist with inverted papilloma and be present in the same biopsy material. There is a high index of suspicion of concomitant malignancy in the presence of severe atypia or hyperkeratosis. Columnar cell papillomas are also associated with an increased risk of malignancy but the rarity of these lesions makes accurate assessment of malignant potential difficult. The most common diagnostic dilemma for pathologists referring cases for second opinion is the recognition of low grade malignancy versus benign inverted papilloma at presentation and in lesions which recur. Recent studies have addressed the requirement for histological parameters to predict the clinical course of these lesions and new molecular markers are being applied to tissue diagnosis. The early recognition and treatment of malignancy associated with inverted papilloma is key to decreased morbidity and improved patient survival and forms the basis of this discussion. PMID:20596982

Epidermal growth factor receptor (EGFR) is a validated target in squamous-cell carcinoma of the head and neck, but in patients with recurrent or metastatic disease, EGFR targeting agents have displayed modest efficacy. Vascular endothelial growth factor (VEGF)-mediated angiogenesis has been implicated as a mechanism of resistance to anti-EGFR therapy. In this multi-institutional phase I/II study we combined an EGFR inhibitor, erlotinib, with an anti-VEGF antibody, bevacizumab. Between April 15, 2003, and Jan 27, 2005, patients with recurrent or metastatic squamous-cell carcinoma of the head and neck were enrolled from seven centres in the USA and were given erlotinib (150 mg daily) and bevacizumab in escalating dose cohorts. The primary objectives in the phase I and II sections, respectively, were to establish the maximum tolerated dose and dose-limiting toxicity of bevacizumab when administered with erlotinib and to establish the proportion of objective responses and time to disease progression. Pretreatment serum and tissues were collected and analysed by enzyme-linked immunosorbent assay and immunofluorescence quantitative laser analysis, respectively. This study was registered with ClinicalTrials.gov, number NCT00055913. In the phase I section of the trial, ten patients were enrolled in three successive cohorts with no dose-limiting toxic effects noted. 46 patients were enrolled in the phase II section of the trial (including three patients from the phase I section) on the highest dose of bevacizumab (15 mg/kg every 3 weeks). Two additional patients were accrued beyond the protocol-stipulated 46, leaving a total of 48 patients for the phase II assessment. The most common toxic effects of any grade were rash and diarrhoea (41 and 16 of 48 patients, respectively). Three patients had serious bleeding events of grade 3 or higher. Seven patients had a response, with four showing a complete response allowing rejection of the null hypothesis. Median time of overall survival and progression-free survival (PFS) were 7.1 months (95% CI 5.7-9.0) and 4.1 months (2.8-4.4), respectively. Higher ratios of tumour-cell phosphorylated VEGF receptor-2 (pVEGFR2) over total VEGFR2 and endothelial-cell pEGFR over total EGFR in pretreatment biopsies were associated with complete response (0.704 vs 0.386, p=0.036 and 0.949 vs 0.332, p=0.036, respectively) and tumour shrinkage (p=0.007 and p=0.008, respectively) in a subset of 11 patients with available tissue. The combination of erlotinib and bevacizumab is well tolerated in recurrent or metastatic squamous-cell carcinoma of the head and neck. A few patients seem to derive a sustained benefit and complete responses were associated with expression of putative targets in pretreatment tumour tissue.

Purpose: The purpose of this study was to investigate early gene expression changes after chemoradiation in a human solid tumor, allowing identification of chemoradiation-induced gene expression changes in the tumor as well as the tumor microenvironment. In addition we aimed to identify a gene expression profile that was associated with clinical outcome. Methods and Materials: Microarray experiments were performed on cervical cancer specimens obtained before and 48 h after chemoradiation from 12 patients with Stage IB2 to IIIB squamous cell carcinoma of the cervix treated between April 2001 and August 2002. Results: A total of 262 genes were identified thatmore » were significantly changed after chemoradiation. Genes involved in DNA repair were identified including DDB2, ERCC4, GADD45A, and XPC. In addition, significantly regulated cell-to-cell signaling pathways included insulin-like growth factor-1 (IGF-1), interferon, and vascular endothelial growth factor signaling. At a median follow-up of 41 months, 5 of 12 patients had experienced either local or distant failure. Supervised clustering analysis identified a 58-gene set from the pretreatment samples that were differentially expressed between patients with and without recurrence. Genes involved in integrin signaling and apoptosis pathways were identified in this gene set. Immortalization-upregulated protein (IMUP), IGF-2, and ARHD had particularly marked differences in expression between patients with and without recurrence. Conclusions: Genetic profiling identified genes regulated by chemoradiation including DNA damage and cell-to-cell signaling pathways. Genes associated with recurrence were identified that will require validation in an independent patient data set to determine whether the 58-gene set associated with clinical outcome could be useful as a prognostic assay.« less

To evaluate the long-term results of exclusive chemotherapy for T1-T3N0M0 glottic squamous cell carcinoma complete clinical responders after induction chemotherapy. Between 1985 and 2000, 69 patients with glottic squamous cell carcinoma complete clinical responders after induction chemotherapy were managed with exclusive chemotherapy at our department. Chemotherapy associated platinum and fluorouracil. This retrospective analysis evaluated actuarial survival, treatment morbidity, oncologic events and laryngeal preservation. Various independent factors were tested for potential correlation with survival and local recurrence. The 5-year Kaplan-Meier actuarial survival, local control, lymph node control estimate were 83,6%, 64,8%, 98,6% respectively. Chemotherapy never resulted in death. The 10-year actuarial metachronous second primary tumors estimate was 32%. The overall laryngeal preservation rate was 98,6%. Altogether our data and the review of the literature suggest that in patients achieving a complete clinical response after and induction based chemotherapy regimen, the completion of an exclusive chemotherapy regimen appears to be a valid alternative to the conventional use of radiotherapy or chemo-radiation protocols.

This integrated, multiplatform PanCancer Atlas study co-mapped and identified distinguishing molecular features of squamous cell carcinomas (SCCs) from five sites associated with smoking and/or human papillomavirus (HPV). SCCs harbor 3q, 5p, and other recurrent chromosomal copy-number alterations (CNAs), DNA mutations, and/or aberrant methylation of genes and microRNAs, which are correlated with the expression of multi-gene programs linked to squamous cell stemness, epithelial-to-mesenchymal differentiation, growth, genomic integrity, oxidative damage, death, and inflammation. Low-CNA SCCs tended to be HPV(+) and display hypermethylation with repression of TET1 demethylase and FANCF, previously linked to predisposition to SCC, or harbor mutations affecting CASP8, RAS-MAPK pathways, chromatin modifiers, and immunoregulatory molecules. We uncovered hypomethylation of the alternative promoter that drives expression of the ΔNp63 oncogene and embedded miR944. Co-expression of immune checkpoint, T-regulatory, and Myeloid suppressor cells signatures may explain reduced efficacy of immune therapy. These findings support possibilities for molecular classification and therapeutic approaches. Published by Elsevier Inc.

Objective: To investigate the different pattern of neck lymph node metastasis, the choice of surgical methods and prognosis in early tongue squamous cell carcinoma. Methods: A total of 157 patients with early oral tongue squamous cell carcinoma were included in this study. Statistical analysis was performed to identify the pattern of lymph node metastasis, to determine the best surgical procedure and to analyze the prognosis. Results: The occurrence of cervical lymph node metastasis rate was 31%(48/157). Neck lymphatic metastasis was significantly related to tumor size ( P= 0.026) and histology differentiation type ( P= 0.022). The rate of metastasis was highest in level Ⅱ [33% (16/48)]. In level Ⅳ, the incidence of lymph node metastasis was 5%(7/157), and there was no skip metastases. The possibility of level Ⅳ metastasis was higher, when level Ⅱ ( P= 0.000) or Ⅲ ( P= 0.000) involved. The differentiation tumor recurrence, neck lymphatic metastasis and adjuvant radiotherapy were prognostic factors ( P< 0.05). Multivariate analyses revealed histology differentiation type, neck lymphatic metastases and adjuvant radiotherapy were the independent prognostic factors. Conclusions: Neck lymphatic metastasis rate is high in early tongue squamous cell carcinoma, simultaneous glossectomy and neck dissection should be performed. Level Ⅳ metastasis rate is extremely low, so supraomohyoid neck dissection is sufficient for most of the time. The histology differentiation type, neck lymphatic metastasis and adjuvant radiotherapy are independent prognostic factors.

Penile squamous cell carcinoma is a rare neoplasm associated with a high risk of metastasis and morbidity. There are limited data on the role of the mTOR signaling pathway in penile squamous cell carcinoma carcinogenesis and tumor maintenance. We assessed a possible role for mTOR signaling pathway activation as a potential predictive biomarker of outcome and a therapeutic target for penile cancer. A cohort of 67 patients diagnosed with invasive penile squamous cell carcinoma from 1987 to 2010 who had known HPV status were selected for study. Tissue microarrays were constructed with 67 primary penile squamous cell carcinomas, matched normal tissues and 8 lymph node metastases. Immunohistochemical staining was performed for p53, pmTOR, pERK, p4E-BP1, eIF4E and peIF4E. Expression was evaluated using a semiquantitative H-score on a scale of 0 to 300. Expression of pmTOR, p4E-BP1, eIF4E and peIF4E was increased in penile tumors compared with matched adjacent normal tissues, indicating activation of the mTOR signaling pathway in penile tumorigenesis. Over expression of pmTOR, peIF4E and p53 was significantly associated with lymph node disease. peIF4E and p53 also correlated with a poor outcome, including recurrence, metastasis or disease specific death. In contrast, pERK and p4E-BP1 were associated with lower pT stages. pmTOR and intense p53 expression was associated with HPV negative tumors. Activation of mTOR signaling may contribute to penile squamous cell carcinoma progression and aggressive behavior. Targeting mTOR or its downstream signaling targets, such as peIF4E, may be a valid therapeutic strategy. Copyright © 2013 American Urological Association Education and Research, Inc.

2018-06-01

Head and neck cancer is one of the most frequent human malignancies worldwide, with a high rate of recurrence and metastasis. Head and neck squamous cell carcinoma (HNSCC) is cellularly and molecularly heterogeneous, with subsets of undifferentiated cancer cells exhibiting stem cell-like properties, called cancer stem cells (CSCs). Epithelial-mesenchymal transition, gene mutation, and epigenetic modification are associated with the formation of cellular plasticity of tumor cells in HNSCC, contributing to the acquisition of invasive, recurrent, and metastatic properties and therapeutic resistance. Tumor microenvironment (TME) plays a supportive role in the initiation, progression, and metastasis of head and neck cancer. Stromal fibroblasts, vasculature, immune cells, cytokines, and hypoxia constitute the main components of TME in HNSCC, which contributes not only to the acquisition of CSC properties but also to the recurrence and therapeutic resistance of the malignancies. In this review, we discuss the potential mechanisms underlying the development of cellular plasticity, especially the emergence of CSCs, in HNSCC. We also highlight recent studies implicating the complex interplays among TME components, plastic CSCs, tumorigenesis, recurrence, and therapeutic resistance of HNSCC. Finally, we summarize the treatment modalities of HNSCC and reinforce the novel concept of therapeutic targeting CSCs in HNSCC.

Purpose: To perform a retrospective analysis of patients with paranasal sinus (PNS) cancer treated with postoperative radiotherapy (RT) at Memorial Sloan-Kettering Cancer Center. Methods and Materials: Between January 1987 and July 2005, 85 patients with PNS and nasal cavity cancer underwent postoperative RT. Most patients had squamous cell carcinoma (49%; n = 42), T4 tumors (52%; n = 36), and the maxillary sinus (53%; n = 45) as the primary disease site. The median radiation dose was 63 Gy. Of the 85 patients, 76 underwent CT simulation and 53 were treated with either three-dimensional conformal RT (27%; n = 23)more » or intensity-modulated RT (35%; n = 30). Acute and late toxicities were scored according to the Radiation Therapy Oncology Group radiation morbidity scoring criteria. Results: With a median follow-up for surviving patients of 60 months, the 5-year estimates of local progression-free, regional progression-free, distant metastasis-free, disease-free, and overall survival rates were 62%, 87%, 82%, 55%, and 67%, respectively. On multivariate analysis, squamous cell histology and cribriform plate involvement predicted for an increased likelihood of local recurrence, and squamous cell histologic features predicted for worse overall survival. None of the patients who underwent CT simulation and were treated with modern techniques developed a Grade 3-4 late complication of the eye. Conclusion: Complete surgical resection followed by adjuvant RT is an effective and safe approach in the treatment of PNS cancer. Emerging tools, such as three-dimensional conformal treatment and, in particular, intensity-modulated RT for PNS tumors, may minimize the occurrence of late complications associated with conventional RT techniques.

Ariga, Hisanori; Nemoto, Kenji; Miyazaki, Shukichi

Purpose: Esophagectomy remains the mainstay treatment for esophageal cancer, although retrospective studies have suggested that chemoradiotherapy (CRT) is as effective as surgery. To determine whether CRT can substitute for surgery as the primary treatment modality, we performed a prospective direct comparison of outcomes after treatment in patients with resectable esophageal cancer who had received CRT and those who had undergone surgery. Methods and Materials: Eligible patients had resectable T1-3N0-1M0 thoracic esophageal cancer. After the surgeon explained the treatments in detail, the patients selected either CRT (CRT group) or surgery (OP group). The CRT course consisted of two cycles of cisplatinmore » and fluorouracil with split-course concurrent radiotherapy of 60Gy in 30 fractions. Patients with progressive disease during CRT and/or with persistent or recurrent disease after CRT underwent salvage resection. Results: Of 99 eligible patients with squamous cell carcinoma registered between January 2001 and December 2005, 51 selected CRT and 48 selected surgery. Of the patients in the CRT group, 13 (25.5%) underwent esophagectomy as salvage therapy. The 3- and 5-year survival rates were 78.3% and 75.7%, respectively, in the CRT group compared with 56.9% and 50.9%, respectively, in the OP group (p = 0.0169). Patients in the OP group had significantly more metastatic recurrence than those in the CRT group. Conclusions: Treatment outcomes among patients with resectable thoracic esophageal squamous cell carcinoma were comparable or superior after CRT (with salvage therapy if needed) to outcomes after surgery alone.« less

Photodynamic therapy of early cancer in the upper aerodigestive tract and bronchi: instrumentation and clinical results

NASA Astrophysics Data System (ADS)

Wagnières, G.

1990-01-01

A complete instrumentation has been developed for photodynamic therapy (PDT) and combined PDT- hyperthermia in the upper aerodigestive tract and the bronchi. These instruments consist of several light distributors which permit optimal light dosage to "superficial" tumors, as well as an injector for laser beams into an optical fiber and a fiberoptic coupler for cw laser beam powers at least 100 Watts. PDT is carried out with HpD and Photofrin II at 630 nm, whereas occasional simultaneous hyperthermia is at 1.06 microns. PDT of 41 cases of "early" squamous cell carcinoma is reported with follow-up between 5 and 62 months. In the oesophagus and bronchi the results are good for cancers staged in situ or microinvasive at endoscopy (2 recurrences for 23 lesions treated). For more advanced cancers (submucosal in the oesopha- gus or invading the bronchial cartilage) the results are less satisfactory with 3 recurrences for 8 lesions treated. In the bronchi (1 case) and the oesophagus (1 case) the largest disease - free survival is now more than 5 years. We encountered 6 complications (3 cicatrical stenosis, 2 fistulae, 1 severe sunburn), most of them resulting from the lack of selectivity of PDT with these porphyrin mixtures at the applied conditions. These experiments show that PDT is efficient at destroying early squamous cell carcinomas in the pharynx, oesophagus and bronchi. Tumour selectivity of HpD and photofrin II is poor in the aerodigestive tract lined with squamous cell epithelium. The future lies in the synthesis of a more selective efficient photosensitizer.

Cancer stem cells contribute to tumor recurrence, and a hypoxic environment is critical for maintaining cancer stem cells. Apigenin is a natural product with anticancer activity. However, the effect of apigenin on cancer stem cells remains unclear. Our aim was to investigate the effect of apigenin on cancer stem cell marker expression in head and neck squamous cell carcinoma cells under hypoxia. We used three head and neck squamous cell carcinoma cell lines; HN-8, HN-30, and HSC-3. The mRNA expression of cancer stem cell markers was determined by semiquantitative RT-PCR and Real-time PCR. The cytotoxic effect of apigenin was determined by MTT colorimetric assay. Flow cytometry was used to reveal the number of cells expressing cancer stem cell surface markers. HN-30 cells, a cancer cell line from the pharynx, showed the greatest response to hypoxia by increasing their expression of CD44, CD105, NANOG, OCT-4, REX-1, and VEGF. Apigenin significantly decreased HN-30 cell viability in dose- and time-dependent manners. In addition, 40μM apigenin significantly down-regulated the mRNA expression of CD44, NANOG, and CD105. Consistent with these results, the hypoxia-induced increase in CD44 + cells, CD105 + cells, and STRO-1 + cells was significantly abolished by apigenin. Apigenin suppresses cancer stem cell marker expression and the number of cells expressing cell surface markers under hypoxia. Copyright © 2016 Elsevier Ltd. All rights reserved.

Strong expression of survivin is associated with worse survival in many different tumours, and in cell culture, a correlation between radiation resistance and survivin expression can be seen. The potential of survivin expression as a prognostic/predictive marker or therapeutic target has not been examined in head and neck squamous cell carcinomas (HNSCC) yet. Retrospective study of 452 tissue samples and clinical data from patients with squamous cell carcinomas of the larynx/hypopharynx (LSCC), oral cavity (OSCC) and oropharynx (OPSCC) treated in the University Medical Centre Hamburg-Eppendorf between 2002 and 2006. The expression patterns were detected by tissue microarray technique and correlated with clinical parameters (sex, age, tumour location, TNM 7th edition, grading, recurrence-free and overall survival). 222 OSCC, 126 OPSCC and 105 LSCC tumours of 118 females and 335 males with a mean follow-up of 41.3 months were examined. Survivin expression correlates with pN, cM, pT and overall survival. The potential of survivin as a prognostic/predictive marker is very high. The findings have to be confirmed in a larger cohort of HNSCC esp. in those tumours treated primarily with radio/radiochemotherapy.

To report rates of recurrence and complications of localized ocular surface squamous neoplasia treated with 5-fluorouracil or mitomycin C as adjunctive treatment to surgical excision. Long-term follow up of two prospective, non-comparative interventional case series. One hundred fifty-three eyes with histologically confirmed localized, non-invasive ocular surface squamous neoplasia. 89 eyes were treated with adjuvant 5-fluorouracil and 64 eyes were treated with adjuvant mitomycin C. Following surgical excision±cryotherapy patients received topical 5-fluorouracil 1% four times daily for two weeks or topical mitomycin C 0.04% four times daily for two to three 1-week cycles. Ocular surface squamous neoplasia recurrence, complications of therapy and compliance. Median follow up was 33.6 (range 12-84) months and 57.9 (range 12-160) months in 5-fluorouracil and mitomycin C groups, respectively. There was one recurrence in the 5-fluorouracil group and no recurrences in the mitomycin C group. Side-effects occurred in 69% of 5-fluorouracil patients and 41% of mitomycin C patients. Five patients (6%) required intervention for treatment-related side-effects in the 5-fluorouracil group versus 11 (17%) in the mitomycin C group. No vision-threatening complications were noted. Long-term recurrence of localised ocular surface squamous neoplasia is rare when topical 5-fluorouracil or mitomycin C are used as adjunctive treatment to surgical excision. While side-effects are common, the majority are transient and rarely limit compliance. © 2013 Royal Australian and New Zealand College of Ophthalmologists.

To explore the RCP protein expression and its clinicopathological significance in laryngeal squamous cell carcinoma (LSCC). RCP protein expression in human head and neck squamous cell carcinoma cell lines (NP-69, Tu686, Tu212, M2 and M4) was analyzed by Western blotting. Besides, its expression in 87 cases of LSCC, 18 cases of adjacent epithelial mucosa and 16 cases of vocal cord leukoplakia was detected by immunohistochemistry, and their correlation with clinicopathological parameters and patients' outcome was analyzed. The NP-69, Tu212 Tu686, M2 and M4 cells showed a gradual increase in the expression of RCP protein. The average relative expression levels of RCP protein in the NP-69, Tu212, Tu686, M2 and M4 cells were 0.05±0.01, 0.38±0.05, 0.63±0.02, 0.84±0.06 and 0.96±0.04, respectively. The same situation occurred in the adjacent mucosa, vocal cord leukoplakia and LSCC. Specifically, only 3 of 18 adjacent mucosa showed a low RCP expression (scored 0-2). Although the 16 cases of vocal cord leukoplakia had a low RCP expression, all their scores ranged from 0 to 3. While in the LSCC specimens, 59 (67.8%) cases demonstrated a high RCP expression (scored 8-15), 18 cases showed a lower RCP expression (scored 4-7), and only 10 cases were scored 2-3. Among the 87 LSCC cases, there were 28 cases (32.2%) of low RCP expression and 59 cases of high RCP expression. All the 18 cases of cancer-adjacent tissues and 16 cases of vocal cord leukoplakia were of low RCP expression. RCP overexpression was significantly associated with T classification, clinical staging, lymph node metastasis and recurrence (P<0.05 for all). Survival analysis revealed that the 5-year survival rate was 40.0% in the patients with high RCP expression and 75.0% in the patients with low RCP expression, the tumor-free 5-year survival rate was 30.7% and 64.0%, respectively, both showing a significant difference between the two subgroups (P<0.05). Univariate analysis revealed that alcohol history; smoking, T classification, clinical staging, lymph node metastasis and RCP expression were significantly associated with a poor prognosis (P<0.05 for all). The multivariate analysis showed that only recurrence and RCP expression were independent prognostic factors affecting the prognosis for patients with LSCC (P<0.05 for both). Expression of RCP protein may contribute to the malignant progression of LSCC, and may become a novel marker predicting tumor recurrence, cervical lymph node metastasis and prognosis for patients with laryngeal squamous cell carcinoma.

To describe the accuracy of the diagnosis of involved excision margins after loop electrosurgical excision procedure (LEEP) in a low-resource setting. Cross-sectional study of 176 LEEPs indicated for a cytological report of high-grade squamous intraepithelial lesion (HGSIL). A total of 72 HIV-positive and 104 HIV-negative women with cervical intraepithelial neoplasia (CIN) ≥ 2 on their LEEP histology report with involved excision margins were enrolled in the study. All patients underwent either a repeat LEEP or a hysterectomy. The specimens were evaluated for residual/recurrent CIN ≥ 2 or less. Persistent/recurrent CIN ≥ 2 was diagnosed in 139 (79.4%) instances and microinvasive squamous cell carcinoma in 6 (3.4%). Thirty (17.2%) showed CIN1. The persistence/recurrence rate was 72.2% and 88.5% in HIV-positive and HIV-negative women, respectively (χ2 = 7.5, p = 0.006). In > 80% the diagnosis of involved excision margins was confirmed, a positive predictive value of 82.4%. In the absence of more accurate follow-up methods such as HPV testing or co-testing with cytology, a correct diagnosis of margin status, especially when involved, is an important guide to further management and follow-up.

Purpose: The aim of this study was to investigate the treatment results of postoperative radiotherapy (PORT) on squamous cell carcinoma of the oral cavity (OSCC). Materials and Methods: This study included 302 OSCC patients who were treated by radical surgery and PORT. Indications for PORT include Stage III or IV OSCC according to the 2002 criteria of the American Joint Committee on Cancer, the presence of perineural invasion or lymphatic invasion, the depth of tumor invasion, or a close surgical margin. Patients with major risk factors, such as multiple nodal metastases, a positive surgical margin, or extracapsular spreading, were excluded.more » The prescribed dose of PORT ranged from 59.4 to 66.6Gy (median, 63Gy). Results: The 3-year overall and recurrence-free survival rates were 73% and 70%, respectively. Univariate analysis revealed that differentiation, perineural invasion, lymphatic invasion, bone invasion, location (hard palate and retromolar trigone), invasion depths {>=}10mm, and margin distances {<=}4mm were significant prognostic factors. The presence of multiple significant factors of univariate analysis correlated with disease recurrence. The 3-year recurrence-free survival rates were 82%, 76%, and 45% for patients with no risk factors, one or two risk factors, and three or more risk factors, respectively. After multivariate analysis, the number of risk factors and lymphatic invasion were significant prognostic factors. Conclusion: PORT may be an adequate adjuvant therapy for OSCC patients with one or two risk factors of recurrence. The presence of multiple risk factors and lymphatic invasion correlated with poor prognosis, and more aggressive treatment may need to be considered.« less

To evaluate therapeutic response to chemoradiotherapy and prediction of recurrence and death in patients with head and neck squamous cell carcinoma (HNSCC) using Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST). Forty-two patients (mean 63.4, range 20-79 years) with nasopharyngeal (n = 10), oropharyngeal (n = 13), hypopharyngeal (n = 11), or laryngeal (n = 8) cancer underwent fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) before and approximately 3 months (mean 95.0, range 70-119 days) after undergoing concurrent chemoradiotherapy. The effect of PERCIST regarding progression-free survival (PFS) and overall survival (OS) was examined using log-rank and Cox methods. Complete metabolic response (CMR), partial metabolic response (PMR), stable metabolic disease (SMD), and progressive metabolic disease shown by PERCIST were seen in 30 (71.4%), 9 (21.4%), 3 (7.1%), and 0 patients, respectively. Fourteen (33.3%) developed recurrent disease (median follow-up 27.2, range 8.7-123.1 months) and 9 (21.4%) died (median follow-up 43.6, range 9.6-132.6 months). Furthermore, 4 (13.3%) of 30 patients with CMR developed recurrence, while 7 (77.8%) of 9 with PMR and all 3 (100%) with SMD developed recurrence. Two (6.7%) of 30 patients with CMR, 4 (44.4%) of 9 with PMR, and all 3 (100%) with SMD died. Patients who achieved CMR showed significantly longer PFS and OS as compared to those who did not (PMR and SMD) (both, p < 0.0001). PERCIST is useful for evaluating therapeutic response to chemoradiotherapy and predicting recurrence and death in HNSCC patients.

Combined biological therapy with 13-cis-retinoic acid (13-cRA) and interferon alpha-2a (IFN alpha-2a) was reported to be highly effective in squamous cell carcinoma of the cervix and skin. Squamous cell carcinoma of the penis is rare in the United States, accounting for less than 1/2% of all male malignancies. Because of the association of infection with human papillomavirus with both carcinomas of the cervix and penis and their shared squamous cell histology, we carried out a phase II study of 13-cRA and IFN alpha-2a in carcinoma of the penis. Eighteen ambulatory patients with surgically unresectable, recurrent, and/or metastatic squamous cell carcinoma of the penis were treated with IFN alpha-2a, 3MU/day administered subcutaneously and 13-cRA, 1 mg/kg orally daily for at least eight weeks, unless intolerable toxicity occurred. One patient was ineligible; one patient withdrew prior to treatment. Among the 16 eligible, treated patients, there was one complete response. Fourteen patients had progressive disease as their only treatment effect. Two patients were unevaluable for tumor response because they had no follow-up tumor measurements. No unexpected treatment-related toxicities were found on study. The only common form of grade 3 toxicity was hypertriglyceridemia found in eight of the 17 patients (47%). No toxicities above grade 3 were observed. In contrast to its benefit in squamous cell carcinomas of the cervix and skin, the combination of 13-cRA and IFN alpha-2a has low efficacy in advanced carcinoma of the penis.

Advanced head and neck squamous cell carcinomas frequently develop distant metastases to limited organs, including the lungs, bone, mediastinal lymph nodes, brain, and liver. Peritoneal carcinomatosis as an initial distant metastasis from hypopharyngeal squamous cell carcinoma is quite rare. A 75-year-old man diagnosed with hypopharyngeal squamous cell carcinoma and his clinical stage was determined as T2N2cM0. Notably, the right retropharyngeal lymph node surrounded more than half of the right internal carotid artery. Concomitant conformal radiation therapy was administered for the primary hypopharyngeal lesion, and the whole neck and tumor response was evaluated at this point according to our algorithm-based chemoradioselection protocol. As the tumor responses at both the primary and lymph nodes were poor, with the right retropharyngeal lymph node in particular demonstrating mild enlargement, we performed a radical surgery: pharyngolaryngectomy, bilateral neck dissection, and reconstruction of the cervical esophagus with a free jejunal flap. Then, postoperative CRT was performed. During these therapies, the patient developed a fever and mild abdominal pain, which was associated with an increased C-reactive protein level. Contrast-enhanced computed tomography from the neck to the pelvis demonstrated mild peritoneal hypertrophy and ascites with no evidence of recurrent and/or metastatic tumor formation. We initially diagnosed acute abdomen symptoms as postoperative ileus. However, cytological examination of the refractory ascites resulted in a diagnosis of peritoneal carcinomatosis. Owing to rapid disease progress, the patient died 1.5 months after abdominal symptom onset. The present case is the second reported case of head and neck squamous cell carcinoma with peritoneal carcinomatosis as an incipient distant metastasis. Therefore, peritoneal carcinomatosis should be considered a differential diagnosis when acute abdomen is noted during treatment for head and neck cancers.

Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy. Biopsy of both tumors revealed a similar histology of well- to moderately differentiated adenocarcinoma. There was no sign of metastases in lymph nodes or other organs. For the purpose of diagnosis and treatment, transperineal local resection of the anal tumor was performed, and it was histologically identified as adenocarcinoma of squamous cells with no invasion to muscles, lymph ducts, or microvessels. The pathological margin was free. Then, to achieve radical cure, laparoscopic low anterior resection (LAR) with D3 lymphadenectomy was performed. The histological diagnosis of the anal tumor was adenocarcinoma of squamous cells without invasion to muscles, lymph ducts, or vessels. The surgical margin was completely free. Immunohistochemical analysis of both tumors revealed similar staining patterns, and the final diagnosis was rectal cancer with metastasis to the anal skin. The patient received no postoperative therapy, and no recurrences have been observed 12 months after surgery. We expect that our sphincter-preserving surgical strategy provided a good prognosis for the synchronous rectal cancer and anal metastasis. This is a rare report of a case with an anal metastasis of colorectal cancer on perianal squamous cells without a history of anal disease that was resected while preserving anal function.

Unusual mucoepidermoid carcinoma of the liver misdiagnosed as squamous cell carcinoma by intraoperative histological examination

PubMed Central

2014-01-01

As rare condition, mucoepidermoid carcinoma may occur in liver although its etiology and pathogenesis is still unclear. We report here a case of intrahepatic mucoepidermoid carcinoma misdiagnosed as cholangiocarcinoma and squamous cell carcinoma by preoperative radiologic and intraoperative histological examinations, respectively. A 60-year-old woman presented with a 1-month history of progressive jaundice, epigastric discomfort, and weight loss with slightly increased carbohydrate antigen 19-9 (CA19-9). Computed tomography (CT) showed a large tumor, 8.0 cm in diameter, in the left lobe of the liver. A preliminary diagnosis of a cholangiocarcinoma of the liver was made. In the intraoperative histological examination, a diagnosis of squamous cell carcinoma was made based on predominantly invasive epidermoid cells with abundant keratinization and absence of mucin-producing cell component. However, postoperative histological diagnosis of the lesion was mucoepidermiod carcinoma of liver by thoroughly microscopical inspection and the presence of mucin-producing cells confirmed by Alcian blue staining. Despite surgical excision and chemotherapy, the tumor showed very aggressive malignancy with tumor recurrence. The patient died shortly afterward, surviving 6 months after surgery. Due to its rarity and distinct morphological features, mucoepidermoid carcinoma might be erroneously interpreted as squamous cell carcinoma by those who were not familiar with this condition in unusual locations. Therefore, removal of sufficient tissue from different portions of the lesion is essential for the surgeons and pathologists to make a precise diagnosis in the intraoperative histological examination.

Background: There is relatively little methylation array data available specifically for oral squamous cell carcinoma (OSCC). This study aims to compare the DNA methylome across a large cohort of tumour/normal pairs. Methods: DNA was extracted from 44 OSCCs and paired normal mucosa. DNA methylation analysis employed the Illumina GoldenGate high-throughput array comprising 1505 CpG loci selected from 807 epigenetically regulated genes. This data was correlated with extracapsular spread (ECS), human papilloma virus (HPV) status, recurrence and 5-year survival. Results: Differential methylation levels of a number of genes distinguished the tumour tissue sample from the matched normal. Putative methylation signatures for ECS and recurrence were identified. The concept of concordant methylation or CpG island methylator phenotype (CIMP) in OSCC is supported by our data, with an association between ‘CIMP-high' and worse prognosis. Epigenetic deregulation of NOTCH4 signalling in OSCC was also observed, as part of a possible methylation signature for recurrence, with parallels to recently discovered NOTCH mutations in HNSCC. Differences in methylation in HPV-driven cases were seen, but are less significant than that has been recently proposed in other series. Conclusion: Although OSCC seems as much an ‘epigenetic' as a genetic disease, the translational potential of cancer epigenetics has yet to be fully exploited. This data points to the application of epigenetic biomarkers and targets available to further the development of therapy in OSCC. PMID:23287992

We present a case of a 71-year-old man with a history of liver transplantation who was treated with adjuvant radiotherapy with concurrent cisplatin for recurrent cutaneous squamous cell carcinoma of the head and neck. The patient was transitioned from tacrolimus to sirolimus for immunosuppression immediately prior to the start of radiation therapy, with the goal of reducing the risk for further skin cancer recurrence. The patient developed severe normal tissue toxicity, disproportionate to the dose delivered. He was diagnosed with Grade 4 esophagitis and mucositis after just 2,400 cGy in 12 fractions (planned 6,400 cGy in 32 fractions), requiring cessation of therapy. Six months later, the patient was diagnosed with local recurrence and distant metastases in the lung, and unfortunately passed away one month later. Randomized data have demonstrated the anti-neoplastic benefit of sirolimus. Pre-clinical studies and animal models have suggested that sirolimus may be a radiation sensitizer; however, the literature is limited regarding the clinical translation of these biologic findings. The case we presented reflects that concurrent radiation therapy with sirolimus may enhance the cytotoxic effects of radiation therapy and contribute to dose-limiting toxicity. Certainly, further study is necessary to explore this observation. Copyright© 2015 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved.

The objective of this study was to determine if matrix metalloproteinase-7 (MMP-7) expression is related to human papilloma virus (HPV) status, clinical parameters, and outcome in oropharyngeal squamous cell carcinoma (OPSCC). Tumor tissue specimens from 201 OPSCC patients treated with curative intent were available for immunohistochemistry, and the samples were stained with monoclonal MMP-7 antibody. All the patients were followed up at least 3 years or until death. MMP-7 expression did not differ between HPV-positive and HPV-negative patients. MMP-7 was not prognostic among patients with HPV-negative OPSCC. In the HPV-positive subgroup, patients with moderate, high, or very high MMP-7 expression had significantly worse 5-year disease-specific survival (DSS) (56.6%) than patients with absent, or low MMP-7 expression (77.2%), and MMP-7 expression appeared as a prognostic factor in the multivariate analysis. In addition, among HPV-positive OPSCC with moderate, high, or very high MMP-7 expression, the 5-year distant recurrence-free survival was significantly lower (69.6%) than in those who had low or absent MMP-7 expression (97.5%). Our results suggest that among HPV-positive OPSCC patients, high MMP-7 expression is related to worse 5-year DSS and increased rate of distant recurrences.

Head and neck squamous cell carcinoma (HNSCC), a heterogeneous group of upper aerodigestive tract malignancies, is the seventh most common cancer worldwide. Tobacco use and alcohol consumption were the most identified risk factors of HNSCC. However, human papilloma virus, a sexually transmitted infection, has been determined as another primary cause of HNSCC. Early-stage disease is treated with surgery or radiotherapy. Recurrent or metastatic HNSCC is associated with poor prognosis with a median overall survival of 10 months. The EXTREME protocol is commonly used in first-line setting. Recently, pembrolizumab, an anti-programmed death-1 agent, has been approved by the US Food and Drug Administration for the treatment of patients with recurrent or metastatic squamous cell carcinoma of the head and neck with disease progression on or after a platinum-based therapy. It demonstrated a durable objective response rate with a good safety profile and quality of life. Many ongoing trials are evaluating the use of pembrolizumab for the treatment of HNSCC in various indications such as adjuvant and neoadjuvant setting, maintenance and recurrent disease, alone or in combination with chemotherapy, radiation and targeted therapy. Finding those biomarkers predictive of response to immune checkpoints inhibitors has been a major concern. However, markers have been identified, such as PD-L1 expression, human papilloma virus infection, interferon-γ signature score, microsatellite instability and neoantigen production.

Unraveling the molecular genetics of head and neck cancer through genome-wide approaches

2014-01-01

The past decade has seen an unprecedented increase in our understanding of the biology and etiology of head and neck squamous cell carcinomas (HNSCC). Genome-wide sequencing projects have identified a number of recurrently mutated genes, including unexpected alterations in the NOTCH pathway and chromatin related genes. Gene-expression profiling has identified 4 distinct genetic subtypes which show some parallels to lung squamous cell carcinoma biology. The identification of the human papilloma virus as one causative agent in a subset of oropharyngeal cancers and their association with a favorable prognosis has opened up avenues for new therapeutic strategies. The expanding knowledge of the underlying molecular abnormalities in this once very poorly understood cancer should allow for increasingly rational clinical trial design and improved patient outcomes.

Chemoradiotherapy in tumours of the oesophagus and gastro-oesophageal junction.

Hulshof, M C C M; van Laarhoven, H W M

2016-08-01

Oesophageal cancer remains a malignancy with a poor prognosis. However, in the recent 10-15 years relevant progress has been made by the introduction of chemoradiotherapy (CRT) for tumours of the oesophagus or gastro-oesophageal junction. The addition of neo-adjuvant CRT to surgery has significantly improved survival and locoregional control, for both adenocarcinoma and squamous cell carcinoma. For irresectable or medically inoperable patients, definitive CRT has changed the treatment intent from palliative to curative. Definitive CRT is a good alternative for radical surgery in responding patients with squamous cell carcinoma and those running a high risk of surgical morbidity and mortality. For patients with an out-of-field solitary locoregional recurrence after primary curative treatment, definitive CRT can lead to long term survival. Copyright © 2016. Published by Elsevier Ltd.

Objective To study the expressions of RNA-binding Ras-GAP SH3 binding protein (G3BP) and tumor stem cell marker CD44v6 in laryngeal squamous cell carcinoma and their correlations with angiogenesis. Methods We collected the cancer tissues and corresponding paracancerous tissues from 56 patients with laryngeal squamous cell carcinoma. The expressions of G3BP and CD44v6 proteins were detected by Western blotting in cancer tissues and corresponding paracancerous tissues; the expressions of G3BP, CD44v6 and vascular endothelial growth factor A (VEGF-A) were tested by immunohistochemistry. Thereafter, we compared the positive expression rates of G3BP and CD44v6 between in cancer tissues and in normal tissues, analyzed the correlations between the expressions of G3BP, CD44v6 and the laryngeal squamous cell carcinoma features as well as their correlations with microvessel density (MVD) that was determined by FVIIIAg immunohistochemistry. Results Western blotting showed that the expressions of G3BP and CD44v6 proteins in the laryngeal squamous cell carcinoma were higher than those in the paracancerous tissues. Immunohistochemistry showed that compared with the paracancerous tissues, G3BP, CD44v6 and VEGF-A expressions (the positive rates are 58.9%, 53.6%, 46.4%, respectively) were higher in cancer tissues. The positive rates of G3BP and CD44v6 in cancer tissues were related with the clinical stage, recurrence or metastasis, and lymph node metastasis of laryngeal squamous cell carcinoma, but had nothing to do with patients' age and tumor size. Pearson correlation analysis showed the expressions of both G3BP and CD44v6 were positively correlated with VEGF-A (r=0.741, r=0.756). MVD values were significantly higher in the G3BP and CD44v6 positive cases than in paracancerous tissues, but there was no difference in MVD between those without G3BP and CD44v6 positive expressions and the paracancerous tissues. Conclusion The positive expression rates of G3BP and CD44v6 in laryngeal squamous cell carcinoma tissues are very high, and they have a close relationship with the clinical prognosis. They may raise the VEGF-A expression so as to promote angiogenesis, and then accelerate the development of the laryngeal squamous cell carcinoma.

This study sought to determine the efficacy and safety profile of lapatinib in patients with recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN). This phase II multiinstitutional study enrolled patients with recurrent/metastatic SCCHN into two cohorts: those without (arm A) and those with (arm B) before exposure to an epidermal growth factor receptor (EGFR) inhibitor. All subjects were treated with lapatinib 1,500 mg daily. Primary endpoints were response rate (arm A) and progression-free survival (PFS; arm B). The biologic effects of lapatinib on tumor growth and survival pathways were assessed in paired tumor biopsies obtained before and after therapy. Forty-five patients were enrolled, 27 in arm A and 18 in arm B. Diarrhea was the most frequent toxicity occurring in 49% of patients. Seven patients experienced related grade 3 toxicity (3 fatigue, 2 hyponatremia, 1 vomiting, and 1 diarrhea). In an intent-to-treat analysis, no complete or partial responses were observed, and stable disease was the best response observed in 41% of arm A (median duration, 50 days, range, 34-159) and 17% of arm B subjects (median, 163 days, range, 135-195). Median PFS was 52 days in both arms. Median OS was 288 (95% CI, 62-374) and 155 (95% CI, 75-242) days for arms A and B, respectively. Correlative analyses revealed an absence of EGFR inhibition in tumor tissue. Lapatinib as a single agent in recurrent/metastatic SCCHN, although well tolerated, appears to be inactive in either EGFR inhibitor naive or refractory subjects. ©2012 AACR.

To identify factors predicting for recurrence in vulvar cancer patients undergoing surgical treatment. We retrospectively evaluated data of consecutive patients with squamous cell vulvar cancer treated between January 1, 1990 and December 31, 2013. Basic descriptive statistics and multivariable analysis were used to design predicting models influencing outcomes. Five-year disease-free survival (DFS) and overall survival (OS) were analyzed using the Cox model. The study included 101 patients affected by vulvar cancer: 64 (63%) stage I, 12 (12%) stage II, 20 (20%) stage III, and 5 (5%) stage IV. After a mean (SD) follow-up of 37.6 (22.1) months, 21 (21%) recurrences occurred. Local, regional, and distant failures were recorded in 14 (14%), 6 (6%), and 3 (3%) patients, respectively. Five-year DFS and OS were 77% and 82%, respectively. At multivariate analysis only stromal invasion >2 mm (hazard ratio: 4.9 [95% confidence interval, 1.17-21.1]; P=0.04) and extracapsular lymph node involvement (hazard ratio: 9.0 (95% confidence interval, 1.17-69.5); P=0.03) correlated with worse DFS, although no factor independently correlated with OS. Looking at factors influencing local and regional failure, we observed that stromal invasion >2 mm was the only factor predicting for local recurrence, whereas lymph node extracapsular involvement predicted for regional recurrence. Stromal invasion >2 mm and lymph node extracapsular spread are the most important factors predicting for local and regional failure, respectively. Studies evaluating the effectiveness of adjuvant treatment in high-risk patients are warranted.

Hypertrophic herpes simplex genitalis (HHSG) is an uncommon anogenital manifestation of herpes simplex virus (HSV) infection in immunocompromised patients. To date, 24 cases of HHSG have been reported; 23 of them were affected human immune deficiency virus (HIV) type 1-positive patients. We describe the case of a 44-year-old African HIV-1-positive woman who presented with painful ulcerated nodular lesions of the vulva and perianal area measuring up to 7 cm in diameter. Macroscopically, the lesions were highly suspicious of widely invasive cancer. The histologic workup of the resection specimen revealed patchy high-grade vulvar intraepithelial neoplasia Grade 3 (VIN 3) and 2 microscopic foci of superficially invasive squamous cell carcinoma. The nodular lesions were caused by massive tumefactive plasma cell-rich inflammatory infiltrates extending into the subcutis. Multinucleated herpes simplex virus 1 and herpes simplex virus 2-positive epithelial cells with glassy intranuclear inclusions were detected at the borders of the ulcerations, consistent with HHSG. Despite repeated surgery and medical treatment, the patient had 3 recurrences of HHSG within 18 months. The presence of intraepithelial neoplasia in HHSG lesions is relatively rare and has been described in 6 of 18 resected HHSG lesions in the literature so far. With regard to invasive malignancy, the present case is the first report of a superficially invasive squamous cell carcinoma associated with HHSG. Awareness of this condition is necessary to avoid misinterpretation of HHSG as widely invasive squamous cell carcinoma with the hazard of surgical and oncological overtreatment.

Streptococcus pyogenes is the main causative pathogen of recurrent tonsillitis. Histologically, lesions of recurrent tonsillitis contain numerous plasma cells. Strep A is an antigenic carbohydrate molecule on the cell wall of S. pyogenes. As expected, plasma cells in subjects with recurrent tonsillitis secrete antibodies against Strep A. The enzyme-labeled antigen method is a novel histochemical technique that visualizes specific antibody-producing cells in tissue sections by employing a biotin-labeled antigen as a probe. The purpose of the present study was to visualize plasma cells producing antibodies reactive with Strep A in recurrent tonsillitis. Firstly, the lymph nodes of rats immunized with boiled S. pyogenes were paraformaldehyde-fixed and specific plasma cells localized in frozen sections with biotinylated Strep A. Secondly, an enzyme-labeled antigen method was used on human tonsil surgically removed from 12 patients with recurrent tonsillitis. S. pyogenes genomes were PCR-detected in all 12 specimens. The emm genotypes belonged to emm12 in nine specimens and emm1 in three. Plasma cells producing anti-Strep A antibodies were demonstrated in prefixed frozen sections of rat lymph nodes, 8/12 human specimens from patients with recurrent tonsillitis but not in two control tonsils. In human tonsils, Strep A-reactive plasma cells were observed within the reticular squamous mucosa and just below the mucosa, and the specific antibodies belonged to either IgA or IgG classes. Our technique is effective in visualizing immunocytes producing specific antibodies against the bacterial carbohydrate antigen, and is thus a novel histochemical tool for analyzing immune reactions in infectious disorders. © 2014 The Authors.

First-line treatment of recurrent and/or refractory head and neck squamous cell carcinoma (HNSCC) is based on platinum, 5-fluorouracil (5-FU) and the monoclonal antiEGFR antibody cetuximab. However, in most cases this chemoimmunotherapy does not cure the disease, and more than 50% of HNSCC patients are dying because of local recurrence of the tumors. In the majority of cases, HNSCC overexpress the epidermal growth factor receptor (EGFR), and its presence is associated with a poor outcome. In this study, we engineered an EGFR-targeted oncolytic measles virus (MV), armed with the bifunctional enzyme cytosine deaminase/uracil phosphoribosyltransferase (CD/UPRT). CD/UPRT converts 5-fluorocytosine (5-FC) into the chemotherapeutic 5-FU, a mainstay of HNSCC chemotherapy. This virus efficiently replicates in and lyses primary HNSCC cells in vitro. Arming with CD/UPRT mediates efficient prodrug activation with high bystander killing of non-infected tumor cells. In mice bearing primary HNSCC xenografts, intratumoral administration of MV-antiEGFR resulted in statistically significant tumor growth delay and prolongation of survival. Importantly, combination with 5-FC is superior to virus-only treatment leading to significant tumor growth inhibition. Thus, chemovirotherapy with EGFR-targeted and CD/UPRT-armed MV is highly efficacious in preclinical settings with direct translational implications for a planned Phase I clinical trial of MV for locoregional treatment of HNSCC.

Perioperative brachytherapy after salvage surgery is a therapeutic option in patients with cervical relapse of a primary, controlled, previously irradiated head and neck squamous cell carcinoma. The purpose of this study was to analyze the outcome of this treatment. Between 2008 and 2013, 8 patients underwent cervical brachytherapy after neck dissection. The mean node size was 5.5 cm. Recurrence occurred in an irradiated field (median dose, 50 Gy). Brachytherapy was performed with (192) iridium and dosimetry in accord with the rules of the Paris system. The dose was 60 to 62.7 Gy on the reference isodose. The mean follow-up was 17 months. The median overall survival (OS) was 12 months. The OS was 19% at 2 years and 0% at 5 years. A grade 5 postoperative adverse event occurred in 1 patient. At 6 months, all patients had a grade 3 neck soft tissue fibrosis. One patient had a lethal hemorrhage at 56 months. Brachytherapy is toxic in this population with poor OS. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2490-E2494, 2016. © 2016 Wiley Periodicals, Inc.

The extent of surgical safety margin (gross tumor border to resection margin) in oral cancer surgery remains unclear, and no study has determined the differential impact of close surgical margin and microscopic extension according to primary tumor size in oral cancers. We retrospectively analyzed the clinical data of 325 patients with surgically treated oral cavity squamous cell carcinomas to determine the effect of a close surgical margin (<5 mm) (cSM 5 ) on local recurrence. In addition, the depth of microscopic tumor infiltration was determined in 90 available surgical specimens. The cSM 5 was not related to the risk of local tumor recurrence in early-stage oral cancer, while it significantly increased the rate of local tumor recurrence in resectable advanced-stage oral cancers (hazard ratio 3.157, 95 % confidence interval 1.050-9.407, p = 0.041). Addition of postoperative adjuvant radiation to early-stage tumors with cSM 5 did not further reduce the local recurrence rate compared to surgery alone. The depth of microscopic tumor extension from the gross tumor border was significantly associated with primary tumor thickness (ρ = 0.390, p < 0.001) and tumor sizes (ρ = 0.308, p = 0.003), which was a median (range) of 0.84 (0.14-2.32) mm in T1, 1.06 (0.20-4.34) mm in T2, and 1.77 (0.13-4.70) mm in T3-4. The cSM 5 was a significant risk factor for local recurrence only in advanced oral cancers, but not in early-stage tumors, where microscopic tumor extension was not beyond 3 mm in T1 tumors. Thus, the extent of surgical safety margin can be redefined according to the primary tumor size.

Because E2F transcription factor 2 (E2F2) promoter polymorphisms have been implicated in carcinogenesis and prognosis, we investigated associations between genetic variants in five E2F2 promoter polymorphisms and recurrence risk of squamous cell carcinoma of the oropharynx (SCCOP) in 1 008 patients. A log-rank test and multivariable Cox models were used to assess the associations. Compared with patients with variant genotypes of E2F2-rs2742976 and E2F2-rs3218123, patients with common homozygous genotypes had better disease-free survival (both log-rank, P < 0.001) and lower SCCOP recurrence risk (HR, 0.4, 95% CI, 0.3-0.6 and HR, 0.3, 95% CI, 0.2-0.5, respectively) after multivariable adjustment. Furthermore, among patients with HPV16-positive tumors, those with common homozygous genotypes of E2F2-rs2742976 and E2F2-rs3218123 had better disease-free survival rates (both log-rank, P < 0.001) and lower recurrence risk (HR, 0.1, 95% CI, 0.1-0.4 and HR, 0.1, 95% CI, 0.0-0.2, respectively) than patients with variant genotypes. However, no significant differences were found for the other three polymorphisms. After combining the risk genotypes of the five polymorphisms and using the high-risk group (2-5 risk genotypes) as the reference group, we found that the low-risk groups (0 or 1 risk genotype) had significantly lower recurrence risk among all patients (HR, 0.4, 95% CI, 0.3-0.6) and among HPV16-positive patients (HR, 0.2, 95% CI, 0.1-0.5). Our findings suggest that E2F2 polymorphisms may individually or jointly modify SCCOP recurrence risk, particularly for SCCOP patients with HPV16-positive tumors. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Purpose: There is a paucity of biomarkers to predict failure in human papillomavirus-positive (HPV + ) oropharyngeal squamous cell carcinoma (OPSCC) following curative therapy. E6/E7 viral oncoproteins are constitutively expressed in HPV + tumors and highly immunogenic, resulting in readily detected serum antibodies. The purpose of this study is to determine whether serum E6 and E7 antibody levels can potentially serve as a biomarker of recurrence in patients with HPV+OPSCC. Experimental Design: We evaluated E6/E7 antibody levels in patients with previously untreated, advanced stage (III, IVa-b), HPV+OPSCC receiving definitive chemoradiation under a uniform protocol from 2003 to 2010. Baseline and longitudinal serum samples were obtained from our archived repository. E6/E7 serum levels were measured using a glutathione- S -transferase capture ELISA and quantified by approximating the area under the dilution curve, and were analyzed using ANOVA and linear mixed model for longitudinal analysis. Results: We compared 22 HPV+OPSCC patients who developed recurrence with 30 patients who remained disease-free. There were no differences in T classification, N classification, disease subsite, or smoking status between the groups. In a longitudinal analysis, recurrent patients had significantly higher E6 and E7 serum antibody levels than the nonrecurrent patients over the follow-up period ( P = 0.02 and P = 0.002, respectively). Patients who recurred had a lower clearance of E7 antibody than patients who remained disease-free ( P = 0.0016). Conclusions: Patients with HPV+OPSCC whose disease recurs have a lower clearance of E6 and E7 antibodies than patients who do not have recurrence. The ratio of E7 antibody at disease recurrence compared with baseline is potentially a clinically significant measurement of disease status in HPV+OPSCC.

Objective: To analyze clinical and prognostic variables of Oral Squamous Cell Carcinoma (OSCC) cases from the indigenous population of Karachi and to correlate with the common risk factor of tobacco habit. Methods: The study was conducted at Ziauddin University, Karachi. One hundred fifty OSCC cases were collected from the Oncology Department of Ziauddin University Hospital, North Nazimabad, Karachi and Otolaryngology ward of Civil Hospital, Karachi, during 2011 and 2015. The reporting included demographic details and variables like intra-oral subsites, clinical stage and histological grade. Recurrence of tumor after initial resection was also documented. Results: The patient’s population comprised of 98 males and 52 females. The mean age was 47.1± 12.22 (range:20-78 years). Maximum numbers were seen in the 41–50 years age group. Urdu-speaking community was the most affected ethnic group (n=75). Clinico-pathological analysis revealed that majority of cases were moderately differentiated (59%) and were either clinical stage II (35%) or IV (29%) tumors. The most common intra-oral subsite came out to be buccal mucosa of cheeks (56%) followed by lateral borders of tongue (21%), lips (13%), alveolar (6%), palate (2.6%) floor of mouth (1.3%), etc. Recurrence was observed in 08 out of 150 cases. All patients underwent primary resection±neck dissection and reconstruction where possible. Conclusions: Overall experience with oral squamous cell carcinoma shows that it has a high tendency for local invasion as well as dissemination to regional lymph nodes, i.e. cervical lymph nodes, both are associated with a poor prognosis. Preventable risk factor of tobacco chewing has been observed in majority of these cases. PMID:27375712

Meticulous mediastinal lymphadenectomy frequently induces recurrent laryngeal nerve palsy (RLNP). Surgical robots with impressive dexterity and precise dissection skills have been developed to help surgeons perform operations. The objective of this study was to determine the impact on short-term outcomes of robot-assisted thoracoscopic radical esophagectomy performed on patients in the prone position for the treatment of esophageal squamous cell carcinoma, including its impact on RLNP. A single-institution nonrandomized prospective study was performed. The patients (n = 36) with resectable esophageal squamous cell carcinoma were divided into two groups: patients who agreed to robot-assisted thoracoscopic esophagectomy with total mediastinal lymphadenectomy performed in the prone position (n = 16, robot-assisted group) without insurance reimbursement, and those who agreed to undergo the same operation without robot assistance but with health insurance coverage (n = 20, control group). These patients were observed for 30 days following surgery to assess short-term surgical outcomes, including the incidence of vocal cord palsy, hoarseness, and aspiration. Robot assistance significantly reduced the incidence of vocal cord palsy (p = 0.018) and hoarseness (p = 0.015) and the time on the ventilator (p = 0.025). There was no in-hospital mortality in either group. There were no significant differences between the two groups with respect to patient background, except for the use of preoperative therapy (robot-assisted group

Helicobacter pylori (H. pylori) has been found in the oral cavity and stomach, and its infection is one of the most frequent worldwide. We reviewed the literature and conducted a Topic Highlight, which identified studies reporting an association between H. pylori-infection in the oral cavity and H. pylori-positive stomach bacterium. This work was designed to determine whether H. pylori is the etiologic agent in periodontal disease, recurrent aphthous stomatitis (RAS), squamous cell carcinoma, burning and halitosis. Record selection focused on the highest quality studies and meta-analyses. We selected 48 articles reporting on the association between saliva and plaque and H. pylori-infection. In order to assess periodontal disease data, we included 12 clinical trials and 1 meta-analysis. We evaluated 13 published articles that addressed the potential association with RAS, and 6 with squamous cell carcinoma. Fourteen publications focused on our questions on burning and halitosis. There is a close relation between H. pylori infection in the oral cavity and the stomach. The mouth is the first extra-gastric reservoir. Regarding the role of H. pylori in the etiology of squamous cell carcinoma, no evidence is still available. PMID:25110422

Mixed squamous cell and glandular papilloma (mixed papilloma) of the lung is exceedingly rare, with only 18 cases reported in the literature. Herein, we report a case of mixed papilloma and its associated immunohistochemical and positron emission tomographic (PET) findings. A 60-year-old Japanese male with a smoking history of 40 pack-years presented with a smooth-edged pulmonary lesion in the right S5 segment on computed tomography (CT). F18-fluorodeoxyglucose (FDG) PET revealed abnormally increased FDG uptake in the mass (maximum standardized uptake value, 3.4). We performed right middle lobectomy and combined partial resection of the S8 segment. The 1.8-cm tumor that filled the enlarged lumen of the B5b was histologically diagnosed as mixed papilloma. Immunohistochemically, the pseudostratified columnar epithelium was positive for cytokeratin (CK) 5/6 and CK7. p40 positivity was predominant in the basal and squamous cells. Thyroid transcription factor-1 and carcinoembryonic antigen were negative on immunostaining. Malignant features were absent. The postoperative course has been uneventful for 3 months after the surgery. No recurrences were reported after the surgical resection of the mixed papilloma. Therefore, surgical resection may be considered the mainstay of curative treatment.

Platinum-based chemotherapy plus cetuximab represents the first-line treatment for recurrent or metastatic squamous cell carcinoma of the head and neck. The most common adverse events associated with cetuximab are infusion reactions and skin reactions, and a risk of venous thromboembolic events has also recently been reported in association with cetuximab. It is well known that thrombosis is a common complication of malignancy, and represents the second most frequent cause of mortality in cancer patients. The present study reports the case of a 79-year-old man who presented with lung and liver metastases from tongue squamous cell carcinoma, for which platinum-based chemotherapy plus cetuximab was administered. After 1 cycle, the patient showed rapid growth of a left ventricular (LV) thrombus, despite ongoing antiplatelet therapy for an old myocardial infarction. Anticoagulant therapy was administered to treat the LV thrombus, which resolved within 1 week. To the best of our knowledge, this represents the first reported case of rapidly occurring LV thrombus associated with platinum-based chemotherapy plus cetuximab. Platinum-based chemotherapy plus cetuximab may be associated with a higher risk of embolic thrombus.

Pembrolizumab and nivolumab are immune checkpoint inhibitors targeting PD-1 that have recently been approved in pretreated recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC) patients. In the clinic, some patients seem not only not to benefit from anti-PD-L1/PD-1 agents but rather to experience an acceleration of tumor growth kinetics (TGK). We retrospectively compared TGK on immunotherapy and TGK on last treatment in patients with R/M HNSCC treated with PD-1/PD-L1 inhibitors in four French centers. The TGK ratio (TGKR, ratio of the slope of tumor growth before treatment and the slope of tumor growth on treatment) was calculated. Hyperprogression was defined as a TGKR ≥ 2. From September 2012 to September 2015, 34 patients were identified. Patterns of recurrence included exclusive loco-regional recurrence in 14 patients, exclusive distant metastases in 11 patients, and both in 9 patients. No pseudo-progression was observed. Hyperprogression was observed in 10 patients (29%), including 9 patients with at least a locoregional recurrence, and only 1 patient with exclusively distant metastases. Hyperprogression significantly correlated with a regional recurrence (TGKR ≥ 2: 90% versus TGKR < 2: 37%, P = 0.008), but not with local or distant recurrence. Hyperprogression was associated with a shorter progression-free survival (PFS) according to RECIST (P = 0.003) and irRECIST (P = 0.02), but not with overall survival (P = 0.77). Hyperprogression was observed in 29% of patients with R/M HNSCC treated with anti-PD-L1/PD-1 agents and correlated with a shorter PFS. It occurred in 39% of patients with at least a locoregional recurrence and 9% of patients with exclusively distant metastases. No pseudo-progressions were reported. Mechanisms and causality of hyperprogression should further be assessed through prospective controlled studies. © The Author 2017.

First-line bevacizumab-based therapy has been shown to improve outcomes in patients with advanced non-squamous non-small-cell lung cancer (NSCLC). The recent international phase IV SAiL study (a Study of Avastin [bevacizumab] in combination with platinum-containing chemotherapy in patients with advanced or recurrent non-squamous cell Lung cancer) evaluated the safety and efficacy of bevacizumab combined with standard chemotherapy regimens in routine clinical practice. Here we report the results of a subanalysis of baseline characteristics and efficacy data for Italian patients enrolled in SAiL. In the SAiL study, patients with untreated locally advanced, metastatic or recurrent non-squamous NSCLC received bevacizumab (7.5 or 15 mg/kg) every 3 weeks plus chemotherapy for up to six cycles, followed by single-agent bevacizumab until disease progression. Efficacy was assessed in terms of time to disease progression (TTP) and overall survival (OS). The Italian intent-to-treat population comprised 215 patients from a SAiL population of 2212 patients. At baseline, Italian patients tended to have less advanced disease than the overall population. Thus, the proportion of patients at enrollment with tumour stage IIIb and IV was 23.7 and 76.3 %, respectively, for the Italian population versus 19.7 and 80.3 % for the whole SAiL population. In addition, a higher proportion of Italian patients had an Eastern Cooperative Oncology Group performance status of 0 (72.6 vs. 37.2 %) and the prevalence of co-morbid conditions was lower in Italian patients (59.5 % of Italian patients reported a co-morbid condition and 60.0 % were receiving non-oncological treatment compared with 73.3 and 73.4 %, respectively, of SAiL patients overall). The mean exposures to bevacizumab and to chemotherapy were comparable between the Italian patient group and overall patient population, although cisplatin doublets were more commonly employed in Italian patients whereas carboplatin doublets were more commonly employed in the overall SAiL population. The median TTP and OS times for Italian and SAiL populations were comparable (TTP, 7.8 months vs. 7.8 months; OS, 14.8 months vs. 14.6 months). The results of this subanalysis of the SAiL study of bevacizumab treatment in routine clinical practice suggest that Italian oncologists tend to prescribe bevacizumab to a selected population of patients with less advanced disease than is the case in the overall population. Nevertheless, the first-line use of bevacizumab in combination with chemotherapy offers clinical benefits to Italian patients with advanced or recurrent non-squamous NSCLC.

Failure of cancer surgery to intraoperatively detect and eliminate microscopic residual disease (MRD) causes lethal recurrence and metastases, whereas removal of important normal tissues causes excessive morbidity. We report plasmonic nanobubble (PNB) surgical technology to intraoperatively detect and eliminate MRD in surgical bed. PNBs were generated in vivo in head and neck cancer cells by systemically targeting tumor with gold colloids and locally-applied near-infrared low energy short laser pulse, and were simultaneously detected with acoustic probe. In mouse models of head and neck squamous cell carcinoma, single cancer cells and MRD (undetectable with standard histological methods) were instantaneously non-invasively detected in solid tissue in surgical bed. In resectable MRD, PNB-guided surgery prevented local recurrence and delivered 100% tumor-free survival. In unresectable MRD, PNB nano-surgery improved survival by two-fold compared to standard surgery. PNB metrics correlated with the tumor recurrence rate. PNB surgical technology precisely detects and immediately eliminates MRD at macro- and micro-scale in a simple and safe intraoperative procedure.

Advances in recurrence and malignant transformation of sinonasal inverted papillomas

Sun, Qingjia; An, Lifeng; Zheng, Jun; Zhu, Dongdong

2017-01-01

Sinonasal inverted papilloma (SIP) is a benign tumor of the nasal cavity and sinus. SIP is characterized by aggressive malignant transformation and a high rate of recurrence. Inadequate removal of the tumor during surgery is one of the most significant contributors to SIP recurrence. A growing body of evidence suggests that molecular alteration in SIP, including human papilloma virus infections, single nucleotide polymorphisms of key genes, deregulation of signaling pathways and immunological changes, may lead to SIP occurrence and malignant transformation. However, the extent to which these molecular mechanisms contribute to SIP pathology and transformation remains unclear due to limited research. Further studies are warranted to elucidate the primary dependent factors that contribute to SIP etiology. The present article reviewed risk factors of progression and recurrence of SIP, including outdoor and industrial occupational exposure, smoking, septal deviation, SIP location, recurrent cases, stage of SIP-associated squamous cell carcinoma and choice of surgical method.

2018-05-08

Sclerosing squamous cell carcinoma (SCC), also known as "desmoplastic" SCC, is a rare subtype of cutaneous malignancy. This variant is clinically significant because it is associated with an increased risk of local recurrence and metastasis. We herein present 16 examples of sclerotic SCC of the skin in 8 men and 3 women, with a median age of 66 years. The most common site of origin for this tumor is the skin of the head and neck, including the scalp (5 tumors in 2 different patients), forehead (3 cases), nasal ala (2 cases), neck (2 cases in the same patient), ear (2 cases), cheek (1 case), and chest (1 case). Microscopically, sclerosing SCCs are characterized by cellular cords, nests, and islands, as well as scattered single cells infiltrating densely desmoplastic and collagenized connective tissue. The differential diagnosis principally includes sclerosing basal cell carcinoma, microcystic adnexal carcinoma, and desmoplastic trichoepithelioma. The main goals of this study are to further characterize these lesions pathologically, and increase general awareness of this SCC subtype.

Head and neck squamous cell carcinoma (HNSCC) includes tumors of various anatomical sites sharing multifactorial etiopathogenesis and generally dismal response to conventional treatment. The objective of this study was to determine the clinical significance of serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) in HNSCC. A total of 46 patients, with histologically-confirmed diagnosis of HNSCC (21 oropharyngeal, 21 laryngeal, and 4 hypopharyngeal cancers) were enrolled in this study. IGF-1 and IGFBP-3 serum levels were measured by an immunoradiometric assay using commercial kits. The adjustment of serum levels at 60 years of age was performed. Significant differences were found in IGF-1 serum concentrations between patients with p16 positive and p16 negative HNSCC (p=0.0062), with higher IGF-1 levels in p16 positive tumors, between low-grade and high-grade cancers (p=0.0323) only in larynx, with elevated IGF-1 concentrations associated with high-grade and between recurrent and non-recurrent HNSCC (p=0.0354), with lower IGF-1 levels in recurrent tumors. The conflicting results of this study may reflect some abnormality of IGF axis regulation in HNSCC, as well as the influence of other etiological factors (e.g. smoking, HPV infection).

To assess whether small oral squamous cell carcinomas (OSCC) require the same margin clearance as large tumors. We evaluated the association between the ratio of the closest margin to tumor size (MSR) and tumor thickness (MTR) with local control and survival. The clinicopathologic and follow up data were obtained for 501 OSCC patients who had surgical resection with curative intent at our institution. MTR and MSR were computed and their associations with local control and survival were assessed using multivariable Cox-regression model. Survival curves were generated using the Kaplan-Meier method. MTR was a better predictor of disease control than MSR. MTR was a predictor of local failure (p=0.033) and disease specific death (p=0.038) after adjusting for perineural invasion, lymphovascular involvement, nodal status, and radiotherapy. A threshold MTR value of 0.3 was identified, above which the risk of local recurrence was low. The ratio of margin to tumor thickness was an independent predictor for local recurrence and disease specific death in this cohort. A MTR>0.3 can serve as a useful tool for adjuvant therapy planning as it combines tumor thickness and margin clearance, two well established prognostic factors. The minimum safe margin can be calculated by multiplying the tumor thickness by 0.3. Further prospective studies in other institutions are warranted to confirm the prognostic utility of MTR and assess the generalizability of our threshold values. Copyright © 2016 Elsevier Ltd.

Chemotherapy for recurrent, metastatic squamous cell carcinoma of the head and neck need not be known for extreme toxicity.The weekly regimen studied here has been demonstrated to be tolerable and effective. The objective of this study was to establish the response rate, progression-free survival (PFS) and overall survival (OS), and safety profile of weekly docetaxel, platinum, and cetuximab (TPC) in patients with relapsed or metastatic squamous cell carcinoma of the head and neck (SCCHN). Twenty-nine patients with metastatic or recurrent SCCHN with an Eastern Cooperative Oncology Group (ECOG) performance status <3 were enrolled in an institutional review board-approved phase II trial. This study permitted prior chemoradiation, radiation, and/or surgery, provided that 3 months had elapsed since the end of the potentially curative treatment. Patients received cisplatin 30 mg/m 2 or carboplatin area under the curve (AUC) 2, docetaxel 30 mg/m 2 , and cetuximab 250 mg/m 2 weekly for 3 weeks, followed by a break during the fourth week, for a 28-day cycle. Planned intrapatient dose modifications were based on individual toxicity. Twenty-seven patients received TPC and were evaluable for response and toxicity. Rates of complete response (CR), partial response (PR), and confirmed PR were 3%, 52%, and 30%, respectively. The overall objective response rate was 56%. Estimated median PFS and OS were 4.8 and 14.7 months, respectively. The rates of grade 3 and 4 worst-grade adverse events (AEs) per patient were 85% and 7%, respectively. Dose density through cycle 4 was preserved for all patients; however, treatment beyond cycle 6 with the TPC regimen proved unfeasible. Weekly docetaxel, cisplatin, and cetuximab is an effective regimen for patients with metastatic or recurrent SCCHN. Response rates, PFS, and OS compare favorably with other combination chemotherapy treatments. Grade 4 toxicity rates observed in this study were substantially lower than those described with regimens using less frequent, higher-dose chemotherapy schedules. © AlphaMed Press; the data published online to support this summary is the property of the authors.

Although the lip is considered a high-risk location in cutaneous squamous cell carcinoma (cSCC), it has not been established whether this risk stems from vermilion or cutaneous locations or both. To compare differences in risks of recurrence, metastasis, and death from cSCCs on the vermilion vs cutaneous lip. Retrospective cohort study of 303 patients with 310 primary cSCCs of the lip (138 cutaneous, 172 vermilion) diagnosed between 2000 and 2015 at 2 academic tertiary care centers in Boston, Massachusetts. Development of local recurrence, nodal metastasis, distant metastasis, disease-specific death, and all-cause death. Of the 303 study participants with 310 SCCs of the lip, 153 (50.5%) were men, and 150 (49.5%) were women; median age at diagnosis, 68 years (range, 27-93 years). Outcomes were as follows for vermilion vs cutaneous locations: local recurrence, 6.4% (11 of 172) vs 2.9% (4 of 138); nodal metastasis, 7.6% (13 of 172) vs 1.5% (2 of 138); distant metastasis, 0.6% (1 of 172) vs 0.7% (1 of 138); disease-specific death, 3.5% (6 of 172) vs 2.9% (4 of 138); and all-cause death, 26.7% (46 of 172) vs 29.0% (40 of 138). The difference was statistically significant for nodal metastasis (P = .01). In multivariable analysis, nodal metastasis was associated with vermilion lip location (subhazard ratio, 5.0; 95% CI, 1.1-23.8) and invasion beyond fat (fascia or beyond for vermilion lip) (subhazard ratio, 4.4; 95% CI, 1.3-14.9). The risk of nodal metastasis is 5-fold greater for cSCCs on the vermilion lip compared with those on the cutaneous lip. Squamous cell carcinomas of the cutaneous lip have a nodal metastasis risk similar to cSCCs in general (1.5%). Thus, vermilion involvement appears responsible for the increased risk associated with cSCC of lip. Vermilion involvement may merit radiologic nodal staging and inclusion in future tumor staging, since it was independently associated with higher-risk cSCC of the lip region.

Lung squamous cell carcinomas (LSCC) pathogenesis remains incompletely understood and biomarkers predicting treatment response remain lacking. Here we describe novel murine LSCC models driven by loss of Trp53 and Keap1, both of which are frequently mutated in human LSCCs. Homozygous inactivation of Keap1 or Trp53 promoted airway basal stem cell (ABSC) self-renewal, suggesting that mutations in these genes lead to expansion of mutant stem cell clones. Deletion of Trp53 and Keap1 in ABSCs, but not more differentiated tracheal cells, produced tumors recapitulating histological and molecular features of human LSCCs, indicating that they represent the likely cell of origin in this model. Deletion of Keap1 promoted tumor aggressiveness, metastasis, and resistance to oxidative stress and radiotherapy (RT). KEAP1/NRF2 mutation status predicted risk of local recurrence after RT in non-small lung cancer (NSCLC) patients and could be non-invasively identified in circulating tumor DNA. Thus, KEAP1/NRF2 mutations could serve as predictive biomarkers for personalization of therapeutic strategies for NSCLCs. PMID:27663899

To evaluate the local control, survival, and toxicity associated with three-dimensional conformal radiotherapy (3D-CRT) for squamous cell carcinoma (SCC) of the esophagus, to determine the appropriate target volumes, and to determine whether elective nodal irradiation is necessary in these patients. A prospective study of 3D-CRT was undertaken in patients with esophageal SCC without distant metastases. Patients received 68.4 Gy in 41 fractions over 44 days using late-course accelerated hyperfractionated 3D-CRT. Only the primary tumor and positive lymph nodes were irradiated. Isolated out-of-field regional nodal recurrence was defined as a recurrence in an initially uninvolved regional lymph node. All 53 patients who made up the study population tolerated the irradiation well. No acute or late Grade 4 or 5 toxicity was observed. The median survival time was 30 months (95% confidence interval, 17.7-41.8). The overall survival rate at 1, 2, and 3 years was 77%, 56%, and 41%, respectively. The local control rate at 1, 2, and 3 years was 83%, 74%, and 62%, respectively. Thirty-nine of the 53 patients (74%) showed treatment failure. Seventeen of the 39 (44%) developed an in-field recurrence, 18 (46%) distant metastasis with or without regional failure, and 3 (8%) an isolated out-of-field nodal recurrence only. One patient died of disease in an unknown location. In patients treated with 3D-CRT for esophageal SCC, the omission of elective nodal irradiation was not associated with a significant amount of failure in lymph node regions not included in the planning target volume. Local failure and distant metastases remained the predominant problems. Copyright 2010 Elsevier Inc. All rights reserved.

Objectives Head and neck squamous cell carcinomas (HNSCC) are common and aggressive tumors that have not seen an improvement in survival rates in decades. These tumors are believed to evade the immune system through a variety of mechanisms and are therefore highly immune modulatory. In order to elucidate their interaction with the immune system and develop new therapies targeting immune escape, new pre-clinical models are needed. Materials and Methods A novel human cell line, USC-HN2, was established from a patient biopsy specimen of invasive, recurrent buccal HNSCC and characterized by morphology, heterotransplantation, cytogenetics, phenotype, gene expression and immune modulation studies and compared to a similar HNSCC cell line; SCCL-MT1. Results and Conclusion Characterization studies confirmed the HNSCC origin of USC-HN2 and demonstrated a phenotype similar to the original tumor and typical of aggressive oral cavity HNSCC (EGFR+CD44v6+FABP5+Keratin+ and HPV−). Gene and protein expression studies revealed USC-HN2 to have highly immune-modulatory cytokine production (IL-1β, IL-6, IL-8, GM-CSF, and VEGF) and strong regulatory T and myeloid derived suppressor cell (MDSC) induction capacity in vitro. Of note, both USC-HN2 and SCCL-MT1 were found to have a more robust cytokine profile and MDSC induction capacity when compared to 7 previously established HNSCC cell lines. Additionally, microarray gene expression profiling of both cell lines demonstrate up-regulation of antigen presenting genes. Because USC-HN2 is therefore highly immunogenic, it also induces strong immune suppression to evade immunologic destruction. Based upon these results, both cell lines provide an excellent model for the development of new suppressor cell-targeted immunotherapies. PMID:21719345

The aim of this study was to evaluate the serum expression levels of squamous cell carcinoma antigen (SCC-Ag), highly sensitive C-reactive protein (hs-CRP), and CA-125 as potential serum biomarkers for recurrence of cervical cancer. Eighty-six cervical cancer patients who received radical treatment were retrospectively included in this study from February 2011 to January 2014. Of the included 86 cases, 23 were recurred within the 36 months (recurrence group [RG]) and other 63 patients did not (non-RG [NRG]). The serum levels of SCC-Ag, hs-CRP, and CA-125 were examined and compared between the two groups. The prediction recurrence sensitivity, specificity area under the receiver operating characteristic curve were calculated by STATA11.0 software (http://www.stata.com). The correlation among SCC-Ag, hs-CRP, and CA-125 were analyzed by Pearson correlation test. The serum levels of SCC-Ag, hs-CRP, and CA-125 were 1.29 (0.21-33.20) mg/mL, 4.78 (0.22-175.20) mg/mL, and 11.56 (2.028-123.66) IU/mL for NRG and 5.64 (0.50-136.80) mg/mL, 22.41 (0.56-588.90) mg/mL, and 25.41 (3.658-3687.00) IU/mL for RG, respectively. The serum levels of SCC-Ag, hs-CRP, and CA-125 in NG group were significant higher than those of NRG group (P < 0.05). The recurrence prediction sensitivity was 0.74, 0.65, and 0.74; specificity was 0.65, 0.63, and 0.58; area under the curve was 0.75, 0.66, and 0.67, respectively, for serum SCC-Ag, hs-CRP, and CA-125. Significant positive correlation between SCC-Ag and hs-CRP (rpearson = 0.20, P = 0.04), SCC-Ag and CA-125 (rpearson = 0.64, P < 0.001), hs-CRP and CA-125 (rpearson= -0.13, P = 0.56) was found in the RG patients. Serum SCC-Ag, hs-CRP, and CA-125 were higher in recurrence cervical patients which could be potential biomarkers for predicting cervical cancer recurrence risk.

Squamous Cell Carcinoma-derived Stem-like Cells (SCC-SC) originate from alterations in keratinocyte stem cells (KSC) gene expression and sustain tumor development, invasion and recurrence. Since survivin, a KSC marker, is highly expressed in SCC-SC, we evaluate its role in SCC-SC cell growth and SCC models. Survivin silencing by siRNA decreases clonal growth of SCC keratinocytes and viability of total, rapidly adhering (RAD) and non-RAD (NRAD) cells from primary SCC. Similarly, survivin silencing reduces the expression of stem cell markers (OCT4, NOTCH1, CD133, β1-integrin), while it increases the level of differentiation markers (K10, involucrin). Moreover, survivin silencing improves the malignant phenotype of SCC 3D-reconstruct, as demonstrated by reduced epidermal thickness, lower Ki-67 positive cell number, and decreased expression of MMP9 and psoriasin. Furthermore, survivin depletion by siRNA in RasG12V-IκBα-derived tumors leads to smaller tumor formation characterized by lower mitotic index and reduced expression of the tumor-associated marker HIF1α, VEGF and CD51. Therefore, our results indicate survivin as a key gene in regulating SCC cancer stem cell formation and cSCC development. PMID:26771605

Context Human papillomavirus (HPV) is a major cause of oropharyngeal squamous cell carcinomas, and HPV (and/or surrogate marker p16) status has emerged as a prognostic marker that significantly impacts clinical management. There is no current consensus on when to test oropharyngeal squamous cell carcinomas for HPV/p16 or on which tests to choose. Objective To develop evidence-based recommendations for the testing, application, interpretation, and reporting of HPV and surrogate marker tests in head and neck carcinomas. Design The College of American Pathologists convened a panel of experts in head and neck and molecular pathology, as well as surgical, medical, and radiation oncology, to develop recommendations. A systematic review of the literature was conducted to address 6 key questions. Final recommendations were derived from strength of evidence, open comment period feedback, and expert panel consensus. Results The major recommendations include (1) testing newly diagnosed oropharyngeal squamous cell carcinoma patients for high-risk HPV, either from the primary tumor or from cervical nodal metastases, using p16 immunohistochemistry with a 70% nuclear and cytoplasmic staining cutoff, and (2) not routinely testing nonsquamous oropharyngeal carcinomas or nonoropharyngeal carcinomas for HPV. Pathologists are to report tumors as HPV positive or p16 positive. Guidelines are provided for testing cytologic samples and handling of locoregional and distant recurrence specimens. Conclusions Based on the systematic review and on expert panel consensus, high-risk HPV testing is recommended for all new oropharyngeal squamous cell carcinoma patients, but not routinely recommended for other head and neck carcinomas.

The purpose of this study was to examine factors related to local treatment failure and determine the outcomes of patients undergoing local salvage resection. This was a retrospective cohort study. This study was conducted at a quaternary referral center. Patients with anal squamous cell carcinoma treated with chemoradiotherapy between January 1983 and December 2015 were included. The influence of patient-, tumor-, and treatment-related factors on the primary outcome measures of locoregional failure, overall survival, and disease-free survival were investigated. Of 467 patients with anal squamous cell carcinoma, 63 experienced locoregional failure with 41 undergoing salvage resection. Twenty-seven patients (38%) had persistent disease and 36 (62%) developed locoregional recurrence. Multivariate analysis identified tumor stage (HR, 3.16; p < 0.002) as an independent predictor of locoregional failure. Thirty abdominoperineal resections and 11 pelvic exenterations were undertaken with no surgical mortality. At a median follow-up of 20 months (range, 4-150 months), 5-year overall and disease-free survival for the salvage cohort was 51% and 47%. Margin positivity was an independent predictor for relapse post-salvage surgery on multivariate analysis (HR, 20.1; p = 0.027). Nineteen patients (48%) developed further relapse, which included all 10 patients with a positive resection margin, 3 of whom underwent re-resection. Of the 19 patients with relapse, 3 remain alive and 2 have persistent disease. Limitations include the retrospective nature of the database, the prolonged time period of the study, and episodes of incomplete data. Advanced T stage is an independent predictor of local failure in anal squamous cell carcinoma. Most patients can be salvaged, with a positive resection margin being a strong predictor of further relapse and poor outcome. See Video Abstract at http://links.lww.com/DCR/A515.

To further understand the clinicopathological, ultrastructural and molecular features of penile pseudoangiosarcomatous squamous cell carcinoma (PASCC), and improve its diagnosis and treatment. A 47-year-old male patient with penile PASCC was reported and the relevant literature reviewed. The main clinical manifestations of the patient were a typical surface ulceration with hemorrhage and purulent secretion with a foul smell, a papillary mass about 5.0 cm x 5.0 cm x 4.0 cm for 1 year on the foreskin of the penis, and 3 enlarged bilateral inguinal lymph nodes. CT scanning showed no enlarged lymph nodes in the abdomen and pelvis, and X-ray examination revealed no abnormality in the chest. The diagnosis was established by biopsy. Partial penectomy and bilateral inguinal lymphadenectomy (T2N2M0) were performed, followed by adjuvant pelvic radiotherapy. Two months later, total penectomy was necessitated by penile flap necrosis and local recurrence. Eleven months after the first surgery, the patient died of extensive metastasis to the pelvis and lungs. Under the light microsope, the tumor was mainly composed of vessel-like lacunar reticularis spindle cells and a few local squamous cancer cells. Careful examination revealed some focal areas with evident transition from squamous nests to the more acantholytic areas extending towards the pseudoangiosarcomatous spaces. Pathogenetically, it appeared to be the variant of acantholytic squamous cell carcinoma. Immunohistochemically, most tumor cells were strongly positive for keratin (AE1/AE3) and focally positive for EMA, with the typical squamous cells focally positive for 34betaE12 and vimentin. The vessels that proliferated in the tumor were decorated by CD31, CD34 and factor VIII-related antigens, but the tumor cells were negative for HMB45, SMA, Desmin and CEA. HPV DNA (HPVpan, HPV6B/11, HPV16/18, HPV31/33) was not detected by in situ hybridization in the primary and metastatic tumors. PASCC is a specific and extremely rare subtype of penile SCC with dramatic similarity to angiosarcoma under the microscope, with poor prognosis. Its diagnosis depends on histopathological, immunohistochemical and ultrastructural studies. Such a presentation underscores the importance of timely consultation, early diagnosis and prompt treatment.

Results of two phase 3 trials have shown first-line bevacizumab in combination with chemotherapy improves clinical outcomes in patients with advanced or recurrent non-squamous non-small-cell lung cancer (NSCLC). The SAiL (MO19390) study was undertaken to assess the safety and efficacy of first-line bevacizumab combined with standard chemotherapy regimens in clinical practice. Between August, 2006, and June, 2008, patients with untreated locally advanced, metastatic, or recurrent non-squamous NSCLC were recruited to this open-label, single group, phase 4 study from centres in 40 countries. Eligible patients had histologically or cytologically documented inoperable, locally advanced, metastatic, or recurrent disease (stage IIIB-IV); an Eastern Cooperative Oncology Group performance status of 0-2; and adequate haematological, hepatic, and renal function. Patients received bevacizumab (7.5 or 15 mg/kg every 3 weeks) plus standard chemotherapy for up to six cycles, followed by single-agent bevacizumab until disease progression. The primary endpoint was safety; analysis was by intention to treat (ITT). This study is registered with ClinicalTrials.gov, number NCT00451906. At the final data cutoff (July 24, 2009), an ITT population of 2212 patients was assessed. The incidence of clinically significant (grade > or = 3) adverse events of special interest was generally low; thromboembolism occurred in 172 (8%) patients, hypertension in 125 (6%), bleeding in 80 (4%), proteinuria in 67 (3%), and pulmonary haemorrhage in 15 (1%). 57 (3%) patients died because of these adverse events, with thromboembolism (26 patients, 1%) and bleeding (17, 1%) as the most common causes. The most common grade 3 or higher serious adverse events deemed by investigators to be associated with bevacizumab were pulmonary embolism (28 patients; 1%) and epistaxis, neutropenia, febrile neutropenia, and deep vein thrombosis (all of which occurred in 13 patients [1%]). Bevacizumab was temporarily interrupted after 28 (2%) of 1347 bleeding events and 72 (7%) of 1025 hypertension events, and permanently discontinued after 110 (8%) bleeding events and 40 (4%) hypertension events. No new safety signals were reported. Our results confirm the manageable safety profile of first-line bevacizumab in combination with various standard chemotherapy regimens for treatment of advanced non-squamous NSCLC.

Perineural spread of tumour cells along cranial nerves is a severe complication of primary cutaneous squamous cell carcinomas of the head and neck region. While surgical excision of the tumour is the treatment of choice, removal of all the tumour is often complicated by the neural location and recurrence is frequent. Non-invasive immune treatments such as checkpoint inhibitor blockade may be useful in this set of tumours although little is understood about the immune response to perineural spread of squamous cell carcinomas. Immunohistochemistry studies suggest that perineural tumour contains a lymphocyte infiltrate but it is difficult to quantitate the different proportions of immune cell subsets and expression of checkpoint molecules such as PD-1, Tim-3 and CTLA-4. Using flow cytometry of excised perineural tumour tissue, we show that a T cell infiltrate is prominent in addition to less frequent B cell, NK cell and NKT cell infiltrates. CD8 T cells are more frequent than other T cells in the tumour tissue. Amongst CD8 T cells, the frequency of Tim-3, CTLA-4 and PD-1 expressing cells was significantly greater in the tumour relative to the blood, a pattern that was repeated for Tim-3, CTLA-4 and PD-1 amongst non-CD8 T cells. Using immunohistochemistry, PD-1 and PD-L1-expression could be detected in close proximity amongst perineural tumour tissue. The data suggest that perineural SCC contains a mixture of immune cells with a predominant T cell infiltrate containing CD8 T cells. Elevated frequencies of tumour-associated Tim-3+, CTLA-4+ and PD-1+ CD8 T cells suggests that a subset of patients may benefit from local antibody blockade of these checkpoint inhibitors.

The role of Rab coupling protein (RCP) has not been previously investigated in squamous cell carcinoma of the head and neck (SCCHN). The aim of this study was to explore RCP protein expression and its clinicopathological significance in SCCHN. RCP protein expression in 95 SCCHN samples, 18 vocal nodule epithelia and 16 leukoplakia epithelia samples was analyzed by immunohistochemistry and correlated with clinicopathological parameters and patient outcome. Our data indicated that vocal nodule epithelia, leukoplakia epithelia and SCCHN showed a gradual increase in the expression of RCP protein. RCP overexpression was significantly associated with T classification, clinical staging, lymph node metastasis and recurrence. Survival analysis revealed that a high RCP expression was significantly correlated with shorter overall survival and disease-free survival. In conclusion, RCP protein may contribute to the malignant progression of SCCHN, and serves as a novel prognostic marker in patients with SCCHN. PMID:22783424

Cases of metastatic anal carcinoma managed with a combination of systemic chemotherapy and local therapies to both solitary sites of metastases and the primary site have been reported in the literature. We present a case of a 55-year-old male with metastatic anal squamous cell carcinoma to the liver treated with induction chemotherapy with cisplatin (CDDP) and 5-fluorouracil (5FU) followed by liver resection and radiation to the anal primary with concurrent 5FU and mitomycin. This approach resulted in control of disease without evidence of recurrence, and no increased toxicities now 19 months from initial diagnosis to time of reporting. This novel approach resulted in a good treatment response as documented by imaging and symptom improvement and a long disease free interval.

Two cases of biopsy-proven conjunctival squamous cell carcinoma (SCC) that developed local and regional spread are described. The cases involved a 65-year-old woman and a 79-year-old man who were initially treated at outside institutions for SCC of the conjunctiva. The patients did not have a history of immune compromise. The female patient presented with direct extension into the lacrimal gland but deferred recommended exenteration. Despite eventual exenteration, she developed metastasis to a neck node 6 months later, which was treated with radiotherapy. The male patient presented with local recurrence and a parotid node metastasis treated with exenteration, parotidectomy, selective neck dissection, and postoperative radiotherapy. Review of the outside pathology of both cases revealed positive tumor margins at the time of original resection. Local control of conjunctival SCC is of critical importance to reduce the risk of orbital extension and regional spread.

The molecular pathogenesis of thymomas and thymic carcinomas (TCs) is poorly understood and results of adjuvant therapy are unsatisfactory in case of metastatic disease and tumor recurrence. For these clinical settings, novel therapeutic strategies are urgently needed. Recently, limited sequencing efforts revealed that a broad spectrum of genes that play key roles in various common cancers are rarely affected in thymomas and TCs, suggesting that other oncogenic principles might be important. This made us re-analyze historic expression data obtained in a spectrum of thymomas and thymic squamous cell carcinomas (TSCCs) with a custom-made cDNA microarray. By cluster analysis, different anti-apoptotic signatures were detected in type B3 thymoma and TSCC, including overexpression of BIRC3 in TSCCs. This was confirmed by qRT-PCR in the original and an independent validation set of tumors. In contrast to several other cancer cell lines, the BIRC3-positive TSCC cell line, 1889c showed spontaneous apoptosis after BIRC3 knock-down. Targeting apoptosis genes is worth testing as therapeutic principle in TSCC.

(1) To compare the anatomopathological variables and recurrence rates in patients with early-stage adenocarcinoma (AC) and squamous cell carcinoma (SCC) of the uterine cervix; (2) to identify the independent risk factors for recurrence. This historical cohort study assessed 238 patients with carcinoma of the uterine cervix (IB and IIA), who underwent radical hysterectomy with pelvic lymph node dissection between 1980 and 1999. Comparison of category variables between the two histological types was carried out using the Pearson's chi(2)-test or Fisher exact test. Disease-free survival rates for AC and SCC were calculated using the Kaplan-Meier method and the curves were compared using the log-rank test. The Cox proportional hazards model was used to identify the independent risk factors for recurrence. There were 35 cases of AC (14.7%) and 203 of SCC (85.3%). AC presented lower histological grade than did SCC (grade 1: 68.6% versus 9.4%; p<0.001), lower rate of lymphovascular space involvement (25.7% versus 53.7%; p=0.002), lower rate of invasion into the middle or deep thirds of the uterine cervix (40.0% versus 80.8%; p<0.001) and lower rate of lymph node metastasis (2.9% versus 16.3%; p=0.036). Although the recurrence rate was lower for AC than for SCC (11.4% versus 15.8%), this difference was not statistically significant (p=0.509). Multivariate analysis identified three independent risk factors for recurrence: presence of metastases in the pelvic lymph nodes, invasion of the deep third of the uterine cervix and absence of or slight inflammatory reaction in the cervix. When these variables were adjusted for the histological type and radiotherapy status, they remained in the model as independent risk factors. The AC group showed less aggressive histological behavior than did the SCC group, but no difference in the disease-free survival rates was noted.

Three-dimensional conformal radiotherapy with concurrent chemotherapy for postoperative recurrence of esophageal squamous cell carcinoma: clinical efficacy and failure pattern

PubMed Central

2013-01-01

Background To assess the therapeutic outcome and failure pattern of three-dimensional conformal radiotherapy (3D-CRT)-based concurrent chemoradiotherapy (CCRT) for recurrence of esophageal squamous cell carcinoma (SCC) after radical surgery. Methods Treatment outcome and failure pattern were retrospectively evaluated in 83 patients with localized cervical and thoracic recurrences after radical surgery for thoracic esophageal SCC. All patients were treated with 3DCRT-based CCRT (median radiation dose 60 Gy), in which 39 received concurrent cisplatin plus 5-fluorouracil (PF), and 44 received concurrent docetaxel plus cisplatin (TP). Treatment response was evaluated at 1–3 months after CCRT. Results With a median follow-up of 34 months (range, 2–116 months), the 3-year overall survival (OS) of all the patients was 51.8% and the median OS time was 43.0 months. The overall tumor response rate was 75.9% (63/83), with a complete remission (CR) rate of 44.6% (37/83). In univariate analysis, tumor response after CCRT (p = 0.000), recurrence site (p = 0.028) and concurrent chemotherapy (p = 0.090) showed a trend favoring better OS. Multivariate analysis revealed that tumor response after CCRT (p = 0.000) and concurrent chemotherapy (p = 0.010) were independent predictors of OS. Forty-seven patients had progressive diseases after CCRT, 27 had local failure (27/47, 57.4%), 18 had distant metastasis (18/47, 38.3%) and 2 had both local and distant failures (2/47, 4.3%). Conclusions 3DCRT-based CCRT is effective in postoperatively recurrent esophageal SCC. Patients that obtained complete remission after CCRT appeared to achieve long-term OS and might benefit from concurrent TP regimen. Local and distant failures remained high and prospective studies are needed to validate these factors. PMID:24139225

We present here the case report of a postmenopausal woman who complained of recurrent pus-like vaginal discharge and perianal pain 1 year after Le Fort colpocleisis, which was subsequently identified as a primary invasive carcinoma of the vagina. Biopsy confirmed a squamous cell carcinoma in the vagina, and the disease was classified as stage III according to FIGO staging. The patient received pelvic radiotherapy. This case emphasizes that differential diagnosis of recurrent vaginal discharge that presents remote from obliterative procedure for pelvic organ prolapse should consider not only pyometra, but also other causes.

Survival and quality of life remain poor for patients with head and neck squamous cell carcinoma (HNSCC) that cannot be fully resected safely, and form therapy-resistant residual and recurrent tumors. We report novel cell-level technology, quadrapeutics. Quadrapeutics converts surgery, drug, and radiation therapies into on-demand microtreatment that unites the diagnosis and treatment in 1 rapid procedure by using 4 standard components: (1) targeted gold colloids; (2) liposomal drugs; (3) a laser pulse; and (4) radiation, all at safe doses. The therapeutic strength of quadrapeutics increases with cancer aggressiveness. In animal models of a primary and microscopic residual HNSCC, quadrapeutics increased the efficacy of standard chemoradiation therapy by more than 17-fold by using only 3% to 6% of clinical doses of drug and radiation, did not cause side effects, and detected residual microtumors in vivo intraoperatively. Quadrapeutics can be applied to detect and eradicate HNSCC and similar microtumors in a safe and rapid theranostic procedure. © 2015 Wiley Periodicals, Inc.

2017-08-01

A 50-year-old female was diagnosed with vulvar cancer treated with left partial vulvectomy and bilateral lymphadenectomy. Ten months after her surgery, she presented with increased labial swelling, pain and discharge. Biopsy confirmed recurrence of squamous cell vulvar carcinoma. Incidentally, on restaging radiographic scans, she was found to have a large right ventricular mass which, after surgical debulking, was shown to be a squamous cell cancer of vulvar origin. She was commenced on chemotherapy with carboplatin and paclitaxel along with concurrent radiation therapy. Restaging PET scan showed persistent metastatic disease. She was switched to Cisplatin/Taxol after having hypersensitivity reaction to Carboplatin. She received 5 cycles with progression of disease in the follow up scans. She then received Nivolumab for 2 cycles. The patient then opted for comfort directed care given worsening functional status and progression of disease on repeat imaging. Secondary cardiac tumors are very rare and not extensively studied in oncology. Therefore, optimal management is not entirely clear. It is extremely rare for vulvar cancer to metastasize to the heart and only two cases have been reported in the literature. However, vulvar cancer metastasizing to the right ventricular cavity and endocardium has not been described before. We believe that this is the first ever such reported case.

Combined Rostrolateral Rhinotomy for Removal of Rostral Nasal Septum Squamous Cell Carcinoma: Long-Term Outcome in 10 Dogs.

Ter Haar, Gert; Hampel, Rachel

2015-10-01

To report a surgical technique for combined rostrolateral rhinotomy (vestibulotomy) and long-term outcome for treatment of squamous cell carcinoma (SCC) of the rostral nasal septum in dogs. Retrospective case series. Medium sized, mixed breed dogs (n = 10), aged 7-12.5 years, with SCC of the rostral nasal septum that did not invade the superficial nasal planum. Disease extent was assessed with computed tomography and tumor resection achieved solely with central nasal planum elevation and lateral rhinotomy. Owners were interviewed 60-2,555 days (median, 548 days) postoperatively to determine outcome and survival time. Vestibulotomy facilitated full-thickness resection of the nasal septum and tumor mass in 10 dogs and nasal floor resection in 4 dogs. There were no major intraoperative complications and all dogs had an excellent cosmetic outcome. Tumor removal was complete in 8 dogs and incomplete in 2 dogs. There was no recurrence in 6 dogs. Of the 4 dogs with recurrence, 3 had required nasal floor resection at initial surgery. A combined rostrolateral rhinotomy technique may be used to achieve complete resection of SCC limited to the nasal septum with acceptable cosmetic results. This technique may not be suitable for tumors extending into the nasal floor. © Copyright 2015 by The American College of Veterinary Surgeons.

Non-melanoma skin cancers are the most common malignancy in humans, with a basal/squamous cell carcinoma incidence ratio of 4:1 in immunocompetent patients. Basal cell carcinoma rarely metastasizes but commonly causes significant local tissue destruction and disfigurement, whereas squamous cell carcinoma is associated with a substantial risk of recurrence and metastasis; the prognosis in metastatic patients is poor. Surgical approaches give a cure rate greater than 90% if appropriately applied, on the basis of the characteristics of the primary tumors and of the patients, but in selected cases, medical treatment (5-fluorouracil, imiquimod, diclofenac and, more recently, ingenol mebutate) is preferable to invasive procedures and provides a good chance of cure, with generally excellent cosmetic outcomes. In case of advanced and metastatic non-melanoma skin cancer, newly developed molecularly targeted therapy represents a reasonably promising alternative to classical cytostatics. In particular, the monoclonal antibody cetuximab, directed against the epidermal growth factor receptor, is effective and well-tolerated in squamous cell carcinoma patients. Moreover, the recent identification of mutations in the Hedgehog signaling pathway in basal cell carcinoma lead to the development of the smoothened Hedgehog pathway inhibitor vismodegib, that was recently approved for the treatment of locally advanced or metastatic basal cell carcinoma. In this review we provide an overview of the molecular pathways involved in NMSC pathogenesis, focusing on the mechanisms of action, indications, efficacy, side effects and contraindications of new medical treatments that specifically tackle molecular targets of these pathways.

A 57-year-old Hispanic man with a personal and family history of bullae and photosensitivity presented with a fungating, ulcerated squamous cell carcinoma on his left hand (Figure 1). Physical examination showed conjunctival injection, ectropion, symblepharon, urethral stricture, loss of teeth, short stature, and nail dystrophy. There was reticulated erythema, atrophy, hyperpigmentation and hypopigmentation, and telangiectasia of sun-exposed skin of the face, neck, and hands consistent with poikiloderma (Figure 2). In addition, there was foreshortening of the left thumb and sclerodermoid changes of his hands (Figure 3). Radiation therapy was applied to shrink the tumor before a local excision was performed. However, a local recurrence followed and axillary lymph nodes became clinically palpable, necessitating amputation and lymph node dissection. Extensive histologic evaluation of the specimen obtained following left arm amputation and lymph node dissection showed moderate-to-poorly differentiated deeply invasive squamous cell carcinoma. Two of 3 axillary lymph nodes were positive for metastatic carcinoma. A random biopsy of the trunk showed epidermal atrophy, telangiectasia, a perivascular lymphocytic infiltration, and pigment-laden macrophages consistent with poikiloderma. Electron microscopy illustrated extensive reduplication of the basement membrane, with loops, curls, and free extensions of the basal lamina in the superficial dermis; reduced numbers of hemidesmosomes and anchoring fibrils; and a basement membrane focally devoid of basal cells (Figure 4). On the basis of the clinical features and the characteristic basement zone changes, a diagnosis of Kindler syndrome was made.

From 1983 to 1996 Phase II and III clinical studies at Henry Ford Hospital demonstrated complete or partial responses in 55 of 56 patients treated with hematoporphyrin-derivative or PHOTOFRIN-mediated photodynamic therapy (HPD-PDT) for a variety of benign and malignant upper aerodigestive tract disease: (1) superficial 'condemned mucosa' or 'field cancerization' of the oral cavity and larynx (7 cases); (2) Stage III/IV head and neck cancer (25 cases); (3) mucocutaneous AIDS-associated Kaposi's sarcoma of the upper aerodigestive tract and non AIDS-related Kaposi's sarcoma of the lower extremity (15 cases); (4) recurrent laryngotracheal papillomatosis (3 cases); (5) severe dysplasia/adenocarcinoma or squamous cell carcinoma in situ in Barrett's esophagus (4 cases); (6) partial or completely obstructing terminal esophageal cancer (9 cases). At the time of this report, HPD-PDT produced complete responses in 24 patients (follow up 6 months to 9 years) with 'field cancerization' (CIS, T1N0M0) of the oral cavity and larynx (6 cases), adenocarcinoma in situ in Barrett's esophagus (3 cases), mucocutaneous Kaposi's sarcoma (12 cases), obstructing esophageal carcinoma (1 case), and stage IV squamous cell carcinoma of the nasopharynx (1 case), and radiation therapy or solar-induced basal cell/squamous cell carcinomas (2 cases). PDT treatment protocols, results, complications, and application as adjunct or primary oncologic therapy for head and neck cancer are reviewed in this article.

Oral cancers are easily accessible compared to many other cancers. Nevertheless, oral cancer is often diagnosed late, resulting in a poor prognosis. Most oral cancers are squamous cell carcinomas that predominantly develop from cell hyperplasias and dysplasias. DNA damage is induced in these tissues directly or indirectly in response to oncogene-induced deregulation of cellular proliferation. Consequently, a DNA Damage response (DDR) and a cell cycle checkpoint is activated. As dysplasia transitions to cancer, proteins involved in DNA damage and checkpoint signaling are mutated or silenced decreasing cell death while increasing genomic instability and allowing continued tumor progression. Hyperphosphorylation of Replication Protein A (RPA), including phosphorylation of Ser4 and Ser8 of RPA2, is a well-known indicator of DNA damage and checkpoint activation. In this study, we utilize S4S8-RPA phosphorylation as a marker for cancer development and progression in oral squamous cell carcinomas (OSCC). S4S8-RPA phosphorylation was observed to be low in normal cells, high in dysplasias, moderate in early grade tumors, and low in late stage tumors, essentially supporting the model of the DDR as an early barrier to tumorigenesis in certain types of cancers. In contrast, overall RPA expression was not correlative to DDR activation or tumor progression. Utilizing S4S8-RPA phosphorylation to indicate competent DDR activation in the future may have clinical significance in OSCC treatment decisions, by predicting the susceptibility of cancer cells to first-line platinum-based therapies for locally advanced, metastatic and recurrent OSCC.

To evaluate the clinical outcomes of total laryngectomy (TL), complications and factors affecting survival. Retrospective review of hospital electronic database for head and neck squamous cell carcinoma (SCCa). Large district general hospital in England, United Kingdom. Patients who had TL between January 1994 and January 2008. 5-year disease specific survival (DSS) and disease-free survival (DFS). Seventy-one patients were reviewed, of whom 38 (54%) had laryngeal SCCa and 33 (46%) hypopharyngeal SCCa. The overall mean survival period following TL was 42.4 months. The 5-year DSS and DFS was better for laryngeal SCCa compared to hypopharyngeal SCCa, although not statistically significant (P=0.090, P=0.54 respectively). Patients treated for laryngeal SCCa had a mean survival period of 47.5 months compared to 36.5 months for hypopharyngeal disease. Those who had laryngeal recurrence after primary radiotherapy (RT) demonstrated statistically better survival probability than those who had hypopharyngeal recurrence (P=0.011). Patients without cervical lymphadenopathy had statistically better survival (P=0.049). The most common early complication was related to the cardiorespiratory system. One fatal complication of erosion of the brachiocephalic artery due to the laryngectomy tube was noted. The most common late complication was neopharyngeal stenosis. The commonest cause of death was due to locoregional recurrence, followed by medical co-morbidities. Patients referred to specialised head and neck clinic had a better survival probability than those referred to a general ENT clinic (P=0.37). While there is increasing tendency towards laryngeal conservation, total laryngectomy remains a robust treatment option in selected patients. Copyright © 2012. Published by Elsevier Masson SAS.

Saliva from submandibular glands (SMG) is necessary to minimize xerostomia. It is unclear whether SMG can be safely spared in patients undergoing bilateral neck radiotherapy for locally advanced oropharyngeal cancer without increasing the risk of marginal recurrence. We evaluated the outcomes of contralateral submandibular gland (cSMG) sparing intensity-modulated radiation therapy (IMRT). All patients with stage III/IV oropharyngeal squamous cell carcinoma treated with bilateral neck IMRT from 2006-2012 at our institution were included. Appropriately selected patients with favorable primary tumor characteristics and no definite contralateral neck disease were treated with cSMG-sparing IMRT. Patterns of failure and xerostomia outcomes were retrospectively analyzed. 114 patients were treated. 89% had stage IV disease and 89% received definitive radiation therapy. 76 patients (67%) received cSMG sparing IMRT. With a median follow-up of 30 months, there were 10 local, 9 regional, and 10 distant recurrences. 2-year overall survival was 86% and 2-year loco-regional control was 87%. In cSMG spared patients, the mean cSMG dose was 30.7 Gy. Late grade 2+ xerostomia was significantly reduced in the cSMG spared group compared to those without SMG sparing (6 months: 23% vs. 72%, 12 months: 6% vs. 41%, 24 months: 3% vs. 36%, all p < 0.0007). There were no peri-SMG marginal recurrences in the cSMG-spared cohort. cSMG sparing IMRT did not increase marginal failures in this series of locally advanced oropharyngeal SCC patients. Xerostomia was significantly reduced in cSMG spared patients.

Lymphomatoid papulosis (LyP) belongs to the group of cutaneous CD30+ lymphoproliferative disorders. Pseudocarcinomatous hyperplasia has rarely been reported in patients with LyP. In this report, we describe a case of LyP presenting as pseudocarcinomatous hyperplasia. The patient was a 7-year-old girl who presented with a recurrent papulonodular eruption on her face and trunk for 2 months. Histopathologic examination revealed an irregular growth of hyperkeratotic epidermis into the whole dermal layer with marked nests of squamous cells in the background of diffuse atypical lymphoid cells, eosinophils and neutrophils. The large atypical cells were positive for CD30 and CD3, but negative for CD4, CD5, CD8, CD20 and CD56. A TCR-γ clone was identified by polymerase chain reaction (PCR). The correct diagnosis in cases of LyP with overlying pseudocarcinomatous epithelial hyperplasia can be very difficult both clinically and histopathologically. Clinical and histopathologic characteristics should be integrated to avoid an erroneous diagnosis of squamous cell carcinoma or keratoacanthoma. © 2015 John Wiley & Sons A/S.

The aim of the research was to evaluate and analyse prognosis and prognostic factors in patients with squamous cell vulvar carcinoma after primary surgery with individual approach applied during the course of treatment. In the period between January 2000 and July 2010, 113 patients with squamous cell carcinoma of the vulva were diagnosed and operated on at Gynecologic Oncology Clinic of Medical University, Pleven. All the patients were monitored at the same clinic. Individual approach was applied to each patient and whenever it was possible, more conservative operative techniques were applied. The probable clinicopathological characteristics influencing the overall survival and recurrence free survival were analyzed. Univariate statistical analysis and Cox regression analysis were made in order to evaluate the characteristics, which were statistically significant for overall survival and survival without recurrence. A multivariate logistic regression analysis (Forward Wald procedure) was applied to evaluate the combined influence of the significant factors. While performing the multivariate analysis, the synergic effect of the independent prognostic factors of both kinds of survivals was also evaluated. Approaching individually each patient, we applied the following operative techniques: 1. Deep total radical vulvectomy with separate incisions for lymph dissection (LD) or without dissection--68 (60.18 %) patients. 2. En-bloc vulvectomy with bilateral LD without vulva reconstruction--10 (8.85%) 3. Modified radical vulvactomy (hemivulvectomy, patial vulvactomy)--25 (22.02%). 4. wide-local excision--3 (2.65%). 5. Simple (total /partial) vulvectomy--5 (4.43%) patients. 6. En-bloc resection with reconstruction--2 (1.77%) After a thorough analysis of the overall survival and recurrence free survival, we made the conclusion that the relapse occurrence and clinical stage of FIGO were independent prognostic factors for overall survival and the independent prognostic factors for recurrence free survival were: metastatic inguinal nodes (unilateral or bilateral), tumor size (above or below 3 cm) and lymphovascular space invasion. On the basis of these results we created two prognostic models: 1. A prognostic model of overall survival 2. A prognostic model for survival without recurrence. Following the surgical staging of the disease, were able to gather and analyse important clinicopathological indexes, which gave us the opportunity to form prognostic groups for overall survival and recurrence-free survival.

Background Conventional cancer therapy including surgery, radiation, and chemotherapy often are physically debilitating and largely ineffective in previously treated patients with recurrent head and neck squamous cell carcinoma (SCC). A natural photochemical, hypericin, could be a less invasive method for laser photodynamic therapy (PDT) of these recurrent head and neck malignancies. Hypericin has powerful photo-oxidizing ability, tumor localization properties, and fluorescent imaging capabilities as well as minimal dark toxicity. The current study defined hypericin PDT in vitro with human SCC cells before the cells were grown as tumor transplants in nude mice and tested as a model for hypericin induced tumor fluorescence and PDT via laser fiberoptics. Methods SNU squamous carcinoma cells were grown in tissue culture, detached from monolayers with trypsin, and incubated with 0.1 μg to 10 μg/ml of hypericin before exposure to laser light at 514, 550, or 593 nm to define optimal dose, time, and wavelength for PDT of tumor cells. The SCC cells also were injected subcutaneously in nude mice and grown for 6–8 weeks to form tumors before hypericin injection and insertion of fiberoptics from a KTP532 surgical laser to assess the feasibility of this operating room instrument in stimulating fluorescence and PDT of tumors. Results In vitro testing revealed a hypericin dose of 0.2–0.5 μg/ml was needed for PDT of the SCC cells with an optimal tumoricidal response seen at the 593 nm light absorption maximum. In vivo tumor retention of injected hypericin was seen for 7 to10 days using KTP532 laser induced fluorescence and biweekly PDT via laser fiberoptics led to regression of SCC tumor transplants under 0.4 cm2 diameter, but resulted in progression of larger size tumors in the nude mice. Conclusion In this preclinical study, hypericin was tested for 514–593 nm dye laser PDT of human SCC cells in vitro and for KTP532 surgical laser targeting of SCC tumors in mice. The results suggest hypericin is a potent tumor imaging agent using this surgical laser that may prove useful in defining tumor margins and possibly in sterilizing post-resection margins. Deeply penetrating pulsed infrared laser emissions will be needed for PDT of larger and more inaccessible tumors. PMID:17147827

Purpose: To review the factors that influence outcome and patterns of relapse in patients with cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with perineural infiltration (PNI) without clinical or radiologic features, treated with surgery and radiotherapy. Methods and Materials: Between 1991 and 2004, 222 patients with SCC or BCC with PNI on pathologic examination but without clinical or radiologic PNI features were identified. Charts were reviewed retrospectively and relevant data collected. All patients were treated with curative intent; all had radiotherapy, and most had surgery. The primary endpoint was 5-year relapse-free survival from the time of diagnosis.more » Results: Patients with SCC did significantly worse than those with BCC (5-year relapse-free survival, 78% vs. 91%; p < 0.01). Squamous cell carcinoma with PNI at recurrence did significantly worse than de novo in terms of 5-year local failure (40% vs. 19%; p < 0.01) and regional relapse (29% vs. 5%; p < 0.01). Depth of invasion was also a significant factor. Of the PNI-specific factors for SCC, focal PNI did significantly better than more-extensive PNI, but involved nerve diameter or presence of PNI at the periphery of the tumor were not significant factors. Conclusions: Radiotherapy in conjunction with surgery offers an acceptable outcome for cutaneous SCC and BCC with PNI. This study suggests that focal PNI is not an adverse feature.« less

In our previous global gene expression analysis, we identified NIPA-like domain containing 1 (NIPAL1), which encodes a magnesium transporter, as one of the most overexpressed genes in recurrent oral squamous cell carcinoma (OSCC). Although has been NIPAL1 linked with gout pathogenesis, little is known about its expression and function in human malignancies. In this study, we examined NIPAL1 expression in 192 cases of OSCC by immunohistochemistry and performed a functional analysis of human OSCC cells. NIPAL1 immunostaining was observed in 39 of 192 OSCC patients (20.3%). NIPAL1 expression correlated significantly with cancer cell intravsation (P = 0.0062), as well as with poorer disease-free survival in a Kaplan-Meier analysis (P < 0.0001). Moreover, a multivariate Cox proportional hazards model analysis revealed that NIPAL1 expression was an independent predictor of disease-free survival in OSCC (P < 0.0001). In a functional analysis, NIPAL1 regulated the growth and adhesion of OSCC tumor cells and endothelial cells. Our findings suggest that NIPAL1 might be a novel factor promoting OSCC tumorigenesis, as well as a useful molecular marker of OSCC.

With the rise of oropharyngeal squamous cell carcinoma associated with human papillomavirus (HPV), appropriate treatment strategies continue to be tailored toward minimizing treatment while preserving oncologic outcomes. This study aimed to compare the outcomes for those undergoing transoral resection with or without adjuvant therapy for HPV-related oropharyngeal carcinoma. A case-match cohort analysis was performed at two institutions on patients with HPV-related oropharyngeal squamous cell carcinoma. All the subjects underwent transoral surgery and neck dissection. The patients treated with surgery alone were matched 1:1 to those treated with surgery and adjuvant therapy using two groups identified as confounders: T-stage (T1/2 or T3/4) and number of pathologically positive lymph nodes (≤4 or >4). The study identified 105 matched pairs, with a median follow-up period of 42 months (range 3.1-102.3 months). The patients were staged as T1/T2 (86%) or T3/4 (14%). Each group had five patients with more than four positive lymph nodes. Adjuvant therapy significantly improved disease-free survival (hazard ratio [HR] 0.067; 95% confidence interval [CI] 0.01-0.62) and was associated with a lower risk of local and regional recurrence (risk ratio [RR] 0.096; 95% CI 0.02-0.47). No difference in disease-specific survival (HR 0.22; 95% CI 0.02-2.57) or overall survival (HR 0.18; 95% CI 0.01-2.4) was observed with the addition of adjuvant therapy. The risk of the gastrostomy tube was higher for those receiving adjuvant therapy (RR 7.3; 95% CI 2.6-20.6). Transoral surgery is an effective approach for the treatment of HPV-related oropharyngeal carcinoma. The addition of adjuvant therapy appears to decrease the risk of recurrence and improve disease-free survival but may not significantly improve overall survival.

To observe the efficacy of intra-arterial chemotherapy with subcutaneously implanted pump for soft tissue sarcoma in extremities and cancerous ulcer. 31 patients with ulcerative skin squamous cell carcinoma or sarcoma in extremities who received treatment during the period from July 2003 to November 2011 at our hospital were recruited, including 15 male and 16 female patients, aging between 14 and 83 with average age of 49 years old. 10 patients had tumor in upper extremities and 21 patients in lower extremities. The pathological types of studied cases include 9 cases with skin squamous cell carcinoma, 6 cases with synovial sarcoma, 5 cases with malignant fibrous histiocytoma, 3 cases with liposarcoma, 3 cases with osteosarcoma, 2 cases with malignant melanoma, 2 cases with epidermoid sarcoma, and 1 case with protuberans. The main symptoms of cancerous ulcer were pain, infection and hemorrhage; All the studied patients were administrated with cisplatin and doxorubicin by intra-arterial chemotherapy pump, and the patients with squamous cell carcinoma were additionally applied with bleomycin and patients with malignant melanoma were additionally applied with dacarbazine. The chemotherapy efficiency was observed after at 3 cycles of intra-arterial chemotherapy. The total remission rate of pain (RR) was 87 %, and total remission rate of ulcer cicatrization (RR) was 71 %, with ulcer cicatrizing spontaneously in 9 cases and obvious homeostasis in 5 cases with bleeding ulcers. 19 patients underwent surgery after chemotherapy, in which 16 cases had limb-salvage surgery and 3 cases underwent lower leg amputation after chemotherapy, and 3 patients out of 16 cases had local recurrence (19 %). The subcutaneous intra-arterial targeting chemotherapy could be applied to treat refractory sarcoma and cancerous ulcer in extremities to significantly increase the chemotherapeutic concentration at tumor area so as to effectively constrain the tumor rupture induced main symptoms including pain, infection and bleeding, which would help to make a decreased blood supplied and well defined tumor boundary to finally decrease the recurrence rate.

Oral Squamous Cell Carcinoma Found Inline with the Fields of Repeat Stereotactic Radiosurgery for Recurrent Trigeminal Neuralgia.

A case of an extremely healthy, active, 96-year-old patient, nonsmoker, is reviewed. He was initially treated for left V1, V2, and V3 trigeminal neuralgia in 2001, at age 80, with stereotactic radiosurgery (SRS) with a dose of 80 Gy to the left retrogasserian trigeminal nerve. He remained asymptomatic for nine years until his trigeminal pain recurred in 2010. He was first treated medically but was intolerant to increasing doses of carbamazepine and gabapentin. He underwent a second SRS in 2012 with a dose of 65.5 Gy to the same retrogasserian area of the trigeminal nerve, making the total cumulative dose 125.5 Gy. In late 2016, four years after the 2 nd SRS, he was found to have invasive keratinizing squamous cell carcinoma in the left posterior mandibular oral mucosa. Keratinizing squamous cell carcinoma is seen primarily in smokers or associated with the human papillomavirus, neither of which was found in this patient. A review of his two SRS plans shows that the left lower posterior mandibular area was clearly within the radiation fields for both SRS treatments. It is postulated that his cancer developed secondary to the long-term radiation effect with a very localized area being exposed twice to a focused, cumulative, high-dose radiation. There are individual reports in the literature of oral mucositis immediately after radiation for trigeminal neuralgia and the delayed development of malignant tumors, including glioblastoma found after SRS for acoustic neuromas, but there are no reports of delayed malignant tumors developing within the general radiation field. Using repeat SRS is an accepted treatment for recurrent trigeminal neuralgia, but physicians and patients should be aware of the potential effects of higher cumulative radiation effects within the treatment field when patients undergo repeat procedures.

One of the common malignant tumors of the head and neck worldwide with generally unfavorable prognosis is squamous cell carcinoma (OSCC) of the oral cavity. Early detection of primary, secondary, or recurrent OSCC by liquid biopsy tools is much needed. Twelve blood biomarkers were used for monitoring a case of OSCC suffering from precancerous oral lichen ruber planus mucosae (OLP). After curative R0 tumor resection of primary OSCC (buccal mucosa), elevated epitope detection in monocytes (EDIM)-Apo10, EDIM-transketolase-like-1 (TKTL1), squamous cell carcinoma antigen (SCC-Ag), total serum lactate dehydrogenase (LDH), and its anaerobic isoforms (LDH-4, LDH-5) decreased to normal levels. Three and six months after surgery, transformation of suspicious mucosal lesions has been accompanied with an increase of EDIM scores, total serum LDH values, and a metabolic shift from aerobic (decrease of LDH-1, LDH-2) to anaerobic (increase of LDH-4, LDH-5) conditions. Two months later, secondary OSCC was histopathologically analyzed after tissue biopsy. Cytokeratin fraction 21-1 (CYFRA 21-1), carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA19-9) were not affected during the clinical course of carcinogenesis. A combination strategy using a standardized panel of established (metabolic) blood biomarkers (TKTL1, LDH, LDH isoenzymes) is worth and can be recommended among others (apoptosis resistance-related Apo10, SCC-Ag) for early detection and diagnosis of primary, secondary, and recurrent OSCC. A tandem strategy utilizing (metabolic pronounced) routine liquid biopsies with imaging techniques may enhance diagnosis of OSCC in the future. Although we demonstrated the diagnostic utility of separated liquid biopsies in our previous study cohorts, further investigations in a larger patient cohort are necessary to recommend this combination strategy (EDIM blood test, LDH value, metabolic shift of LDH isoenzymes, and others, e.g., SCC-Ag or immunophenotyping) as a diagnostic tool for the addition to the OSCC staging system and as a routine procedure in the aftercare.

Squamous odontogenic tumor and squamous odontogenic tumor-like proliferations in odontogenic cysts: An updated analysis of 170 cases reported in the literature.

Chrcanovic, Bruno Ramos; Gomez, Ricardo Santiago

2018-03-01

To integrate the available data published on squamous odontogenic tumors (SOT) and squamous odontogenic tumor-like proliferations in odontogenic cysts (SOT-LPOC) into a comprehensive analysis of their clinical/radiologic features. An electronic search was undertaken in January 2017. Eligibility criteria included publications having enough clinical/radiological/histological information to confirm a definite diagnosis. A total of 74 publications reporting 110 SOTs (102 central, 8 peripheral) and 60 SOT-LPOC were included. Compared to SOT-LPOC, SOT showed lower mean age, no preference regarding maxilla or mandible localization, significant association with cortical bone perforation, multilocular radiographic appearance, and mobility of the tooth/teeth associated with the lesion. While 5 recurrent SOT were reported after enucleation, no recurrent SOT-LPOC was found. SOT shows a more aggressive biologic behavior than SOT-LPOC, which supports the hypothesis that the two lesions are distinct clinicopathological conditions.

To demonstrate a safe and effective method for complete resection of squamous papilloma in the nasopharyngeal surface of the soft palate. This technique was used on a patient in whom the papilloma had twice recurred following uvulopalatopharyngoplasty. Case report and review of the relevant literature. The patient reported in this paper had recurrent squamous papilloma in the nasopharyngeal surface of the soft palate following uvulopalatopharyngoplasty. He also suffered from nasal regurgitation when drinking water. This lesion, which was difficult to access, was successfully treated via a transnasal endoscopic approach using powered instrumentation. This case report highlights a novel approach for the complete removal of a recurrent papilloma in a relatively inaccessible location. Compared with a transoral approach such as uvulopalatopharyngoplasty, the transnasal endoscopic approach using powered instrumentation could provide a safer, faster, easier and less invasive means of treating squamous papilloma in the nasopharyngeal surface of the soft palate, especially for a lesion that recurs following a transoral approach.

Extranodal invasion (ENI) has been reported to be associated with a poor prognosis in several malignancies. However, previous studies have included perinodal fat tissue tumor deposits in their definitions of ENI. To investigate the precise nature of ENI in esophageal squamous cell carcinoma (ESCC), we excluded these tumor deposits from our definition of ENI and defined tumor cell invasion through the lymph node capsule and into the perinodal tissues as lymph node capsular invasion (LNCI). The aim of the current study was to elucidate the significance of LNCI in ESCC. We investigated the associations between LNCI and other clinicopathologic features in 139 surgically resected ESCC. We also investigated the prognostic significance of LNCI in ESCC. LNCI was detected in 35 (25.2%) of 139 patients. The overall survival rate of the ESCC patients with LNCI was significantly lower than that of the ESCC patients with lymph node metastasis who were negative for LNCI. The survival difference between the patients with 1–3 lymph node metastases without LNCI and those with no lymph node metastasis was not significant. LNCI was significantly associated with distant organ recurrence. LNCI was also found to be an independent predictor of overall survival in addition to the number of lymph node metastases. LNCI in ESCC patients is an indicator of distant organ recurrence and a worse prognosis. LNCI could be used as a candidate marker for designing more precise staging and therapeutic strategies for ESCC.

The prognosis of head and neck squamous cell carcinoma (HNSCC) is largely based on disease stage. Despite improvements in treatment, recurrence rates are still considered high. Currently, disease progression or regression after curative treatment is monitored by clinical evaluation combined with flexible endoscopy and/or imaging. However, specificity of imaging is low due to the posttreatment effects. Detection of circulating tumor DNA (ctDNA) from blood samples of HNSCC patients is a minimally invasive technique that could lead to an earlier detection of recurrence. In addition, digital droplet PCR (ddPCR) could be used to sensitively detect these mutational targets. Future study on ctDNA using ddPCR in blood samples of HNSCC patients is recommended during the follow-up stage to detect recurrences in a timely manner. © 2016 S. Karger AG, Basel.

There is currently no consensus regarding the optimal postoperative follow-up strategy for patients with completely resected non-small cell lung cancer (NSCLC). We aimed to develop web-based nomograms to precisely predict site-specific postoperative recurrence in patients with NSCLC and to guide individual surveillance strategies including when to follow up and what diagnostic tests to perform. We investigated the pattern of recurrence in a series of 2,017 patients with NSCLC (squamous cell carcinoma and nonlepidic invasive adenocarcinoma) who underwent complete surgical resection at Fudan University Shanghai Cancer Center (development cohort), and developed web-based clinicopathologic prediction models for conditional risk of site-specific recurrence based on Cox regression. The variables used in the analysis included sex, age, smoking history, tumor size, tumor histology, lymphovascular invasion, visceral pleural invasion, and pathologic TNM stage. A separate cohort of 3,308 patients with NSCLC from Shanghai Chest Hospital was used for external validation. In the development cohort and the external validation cohort for the established nomograms to predict overall recurrence, thorax recurrence, abdomen recurrence, neck recurrence, brain recurrence, and bone recurrence, the C-statistics of Harrell et al were 0.743 and 0.748, 0.728 and 0.703, 0.760 and 0.749, 0.779 and 0.757, 0.787 and 0.784, and 0.777 and 0.739, respectively. The calibration plots showed optimal agreement between nomogram-predicted 3-year recurrence-free survival and actual 3-year recurrence-free survival. These user-friendly nomograms can precisely predict site-specific recurrence in patients with completely resected NSCLC, based on clinicopathologic features. They may help physicians to make individual postoperative follow-up plans. Copyright © 2018 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.

Fibroblasts play a central role in tumor invasion, recurrence, and metastasis in head and neck squamous cell carcinoma. The aim of this study was to investigate the influence of tumor cell self-produced factors and paracrine fibroblast-secreted factors in comparison to indirect co-culture on cancer cell survival, growth, migration, and epithelial-mesenchymal transition using the cell lines SCC-25 and human gingival fibroblasts. Thereby, we particularly focused on the participation of the fibroblast-secreted transforming growth factor beta-1.Tumor cell self-produced factors were sufficient to ensure tumor cell survival and basic cell growth, but fibroblast-secreted paracrine factors significantly increased cell proliferation, migration, and epithelial-mesenchymal transition-related phenotype changes in tumor cells. Transforming growth factor beta-1 generated individually migrating disseminating tumor cell groups or single cells separated from the tumor cell nest, which were characterized by reduced E-cadherin expression. At the same time, transforming growth factor beta-1 inhibited tumor cell proliferation under serum-starved conditions. Neutralizing transforming growth factor beta antibody reduced the cell migration support of fibroblast-conditioned medium. Transforming growth factor beta-1 as a single factor was sufficient for generation of disseminating tumor cells from epithelial tumor cell nests, while other fibroblast paracrine factors supported tumor nest outgrowth. Different fibroblast-released factors might support tumor cell proliferation and invasion, as two separate effects.

The molecular pathogenesis of thymomas and thymic carcinomas (TCs) is poorly understood and results of adjuvant therapy are unsatisfactory in case of metastatic disease and tumor recurrence. For these clinical settings, novel therapeutic strategies are urgently needed. Recently, limited sequencing efforts revealed that a broad spectrum of genes that play key roles in various common cancers are rarely affected in thymomas and TCs, suggesting that other oncogenic principles might be important. This made us re-analyze historic expression data obtained in a spectrum of thymomas and thymic squamous cell carcinomas (TSCCs) with a custom-made cDNA microarray. By cluster analysis, different anti-apoptotic signatures were detected in type B3 thymoma and TSCC, including overexpression of BIRC3 in TSCCs. This was confirmed by qRT-PCR in the original and an independent validation set of tumors. In contrast to several other cancer cell lines, the BIRC3-positive TSCC cell line, 1889c showed spontaneous apoptosis after BIRC3 knock-down. Targeting apoptosis genes is worth testing as therapeutic principle in TSCC. PMID:24427739

Erbium laser resurfacing for actinic cheilitis.

PubMed

Cohen, Joel L

2013-11-01

Actinic cheilitis is a precancerous condition characterized by grayish-whitish area(s) of discoloration on the mucosal lip, often blunting the demarcation between mucosa and cutaneous lip. Actinic cheilitis is considered to be an early part of the spectrum of squamous cell carcinoma. Squamous cell carcinoma specifically of the lip has a high rate of recurrence and metastasis through the oral cavity leading to a poor overall survival. Risk factors for the development of actinic cheilitis include chronic solar irradiation, increasing age, male gender, light skin complexion, immunosuppression, and possibly tobacco and alcohol consumption. Treatment options include topical pharmacotherapy (eg, fluorouracil, imiquimod) or procedural interventions (eg, cryotherapy, electrosurgery, surgical vermillionectomy, laser resurfacing), each with their known advantages and disadvantages. There is little consensus as to which treatment options offer the most clinical utility given the paucity of comparative clinical data. In my practice, laser resurfacing has become an important tool for the treatment of actinic cheilitis owing to its ease of use and overall safety, tolerability, and cosmetic acceptability. Herein the use of erbium laser resurfacing is described for three actinic cheilitis presentations for which I find it particularly useful: clinically prominent actinic cheilitis, biopsy-proven actinic cheilitis, and treatment of the entire lip following complete tumor excision of squamous cell carcinoma. All patients were treated with a 2940-nm erbium laser (Sciton Profile Contour Tunable Resurfacing Laser [TRL], Sciton, Inc., Palo Alto, CA).

Small size of metastatic lymph nodes with extracapsular spread greatly impacts treatment outcomes in oral squamous cell carcinoma patients.

Extracapsular spread (ECS) of metastatic lymph nodes from oral carcinoma is the most significant prognostic predictor of a poor treatment outcome. However, only a few reports on prognostic factors in ECS-positive cases have been investigated. To address this problem, a detailed examination of ECS pathology was conducted to determine the prognostic factors of oral squamous cell carcinoma (OSCC) with ECS of metastatic lymph nodes. This study involved 63 OSCC patients with at least one pathologically metastatic node with ECS. Among the 229 metastatic lymph nodes, 149 exhibited ECS. Univariate analysis revealed that a poor outcome and recurrence were significantly associated with the number of ECS-positive nodes, density of ECS, and the minor axis of the smallest ECS-positive node. However, multivariate analysis identified only small size of ECS-positive nodes as a significant and independent factor predicting recurrence and a poor outcome. Thus, small size of ECS-positive nodes is the most important prognostic indicator for OSCC with ECS in metastatic lymph nodes. The classification of ECS status using the minor axis of ECS-positive nodes may be useful for further prediction of a poorer prognosis in OSCC cases. Standardization of ECS diagnosis and multicenter prospective studies will be required to confirm and refine these findings.

Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor (VEGF), which is a key regulator of tumor angiogenesis. To evaluate biomarkers to predict the benefit of paclitaxel and carboplatin plus bevacizumab (PCB) therapy in patients with advanced or recurrent non-squamous non-small cell lung cancer. Among 21 patients treated with PCB, 10 were included in the good responder group and 11 in the non-responder group. Serum VEGF, MMP-2 and MMP-9 were measured using ELISA. There were no significant differences in these markers levels between groups. However, the good responder group showed a significantly higher pre-treatment MMP-9/ absolute neutrophil count (ANC) score than the non-responder group before the treatment (p= 0.014), and there was a positive correlation between the score and the tumor reduction rate (r= 0.57, p= 0.016). Furthermore, by dividing patients into a high scoring group (MMP-9/ANC ≥ median, n= 11) and a low scoring group (MMP-9/ANC < median, n= 10), former group showed a significant improvement in the median progression-free survival compared with latter group (636 vs. 196 days, p = 0.032). MMP-9/ANC score before PCB treatment may be a suitable biomarker to assess the anti-tumor effects of PCB therapy.

Emerging role of sphingosine-1-phosphate signaling in head and neck squamous cell carcinoma.

2016-01-01

Head and neck squamous cell carcinoma (HNSCC) is the sixth most frequent cancer type, with an annual incidence of approximately half a million people worldwide. It has a high recurrence rate and an extremely low survival rate. This is due to limited availability of effective therapies to reduce the rate of recurrence, resulting in high morbidity and mortality of patients with advanced stages of the disease. HNSCC often develops resistance to chemotherapy and targeted drug therapy. Thus, to overcome the problem of drug resistance, there is a need to explore novel drug targets. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid involved in inflammation, tumor progression, and angiogenesis. S1P is synthesized intracellularly by two sphingosine kinases (SphKs). It can be exported to the extracellular space, where it can activate a family of G-protein-coupled receptors. Alternatively, S1P can act as an intracellular second messenger. SphK1 regulates tumor progression, invasion, metastasis, and chemoresistance in HNSCC. SphK1 expression is highly elevated in advanced stage HNSCC tumors and correlates with poor survival. In this article, we review current knowledge regarding the role of S1P receptors and enzymes of S1P metabolism in HNSCC carcinogenesis. Furthermore, we summarize the current perspectives on therapeutic approaches for targeting S1P pathway for treating HNSCC.

D. Due to the high prevalence of skin cancers after organ transplantation, it is highly recommended to inform patients about self-awareness. E. Primary prevention should include the avoidance of sun exposure, use of protective clothing and use of an effective sunscreen (protection factor >15) for unclothed body parts (head, neck, hands and arms) in order to prevent the occurrence of squamous-cell carcinoma. This is the most frequent skin tumour in transplant recipients, and its preferential location is the head. F. Recipients with pre-malignant skin lesions (warts, epidermodysplasia verruciformis or actinic keratoses) should be referred early to a dermatologist for active treatment and close follow-up. G. All skin cancers should be completely removed by a dermatologist with appropriate techniques, such as electro-desiccation with curettage, cryotherapy or surgical excision. H. Secondary prevention for recipients should include close follow-up by a dermatologist (at least every 6 months), the use of topical retinoids to control actinic keratoses and to diminish squamous-cell carcinoma recurrence, and reduction of immunosuppression whenever possible. I. In recipients with multiple and/or recurrent skin cancers, the use of systemic retinoids, such as low-dose acitretin, could be recommended for months/years, if well tolerated, in addition to further reduction in immunosuppression whenever possible.

INTRODUCTION The aim of this study was to investigate the prevalence of risk factors for primary squamous cell carcinoma (SCC) of the bladder. MATERIALS A total of 90 cases of primary SCC of the bladder were identified through multicentre analysis. Patient demographics, stage and grade of cancer at presentation, management and outcomes were recorded. The presence of known risk factors (catheter use, neuropathic bladder, smoking history, recurrent urinary tract infection and bladder stones) was also documented. RESULTS Over half of the patients had at least one identifiable risk factor for the development of primary bladder SCC: 13.9% of patients had a history of catheter use (clean intermittent self-catheterisation [CISC] in 11.1%), 10.0% of patients had a neuropathic bladder, 27.8% were smokers or ex-smokers and 20.0% had a documented history of recurrent urinary tract infection. Statistical analysis of the results showed no association between risk factors and grade of tumour at presentation. CONCLUSIONS These data further support the association between primary bladder SCC and several of the well documented risk factors for its development. Chronic use of CISC may confer a greater risk for development of SCC than thought previously. Further evidence of the role of CISC in primary SCC is required to justify routine screening and to determine exactly when surveillance of the bladder should begin for this group of patients.

Oropharyngeal squamous cell carcinoma (SCC) is frequently related to high risk human papillomavirus. This tumor expresses p16, frequently has a nonkeratinizing morphology, and has improved outcomes. Despite having a good prognosis, tumors can have focal or diffuse nuclear anaplasia or multinucleation, the significance of which is unknown. From a database of 270 oropharyngeal SCCs with known histologic typing (using our established system) and p16 immunohistochemistry, all surgically resected cases (149) were reviewed. Anaplasia was defined as any × 40 field with ≥ 3 tumor nuclei with diameters ≥ 5 lymphocyte nuclei (~25 μm), and multinucleation was defined as any × 40 field with ≥ 3 tumor cells with multiple nuclei. p16 was positive in 128 cases (85.9%), 64 cases (43.0%) showed anaplasia, and 71 (47.7%) showed multinucleation. Anaplasia and multinucleation were highly related (P<0.001), and both also correlated with histologic type (P<0.001 and P=0.01, respectively), p16 status (P=0.09 and 0.03, respectively), and partially with nodal extracapsular extension. There was no correlation with any of the other variables. In univariate analysis, cases showing anaplasia or multinucleation had worse overall, disease-specific, and disease-free survival (P<0.006 for all). Higher T-stage, keratinizing histologic type, extracapsular extension, and smoking also all correlated with worse survival. In multivariate analysis, anaplasia and multinucleation both predicted worse disease-specific survival (hazard ratio 9.9, P=0.04; and hazard ratio 11.9, P=0.02, respectively) independent of the other variables. In summary, among surgically resectable oropharyngeal SCC (including among just the p16-positive cohort), tumor cell anaplasia and multinucleation independently correlated with disease recurrence and poorer survival.

2013-01-01

The benign lesions of the lacrimal sac are very rare. The most typical epithelial tumor is squamous papilloma. This tumors often present with symptoms of dacryostenosis and dacriocystitis. Human papillomavirus (HPV) infection is known to be causative agent in the development of epithelial tumor. Lacrimal sac tumors could transform to malignant neoplasms, especially if they are developed of coexisting HPV infection. We present a patient with a squamous papilloma of the lacrimal sac and discussed the method of treatment. The patient was suffered from epiphora and recurrent dacriocystitis. An endoscopic surgery with dacriocystorhinostomy and local resection of the tumor could be an effective method of choice. The usage of a shaver for wide removal of the lacrimal sac wall is recommended to prevent local recurrence. The histopathology examination showed squamous papilloma. The patient is free of the disease over 8 months of follow up. Primary lacrimal sac papilloma require long term follow up for recurrence or malignant transformation. HPV infection could be associated with the development of lacrimal sac papillomas. Copyright © 2012 Polish Otorhinolaryngology - Head and Neck Surgery Society.

Purpose Myeloid-derived suppressor cells (MDSC) and regulatory T cells (Treg) play a key role in the progression of head and neck squamous cell carcinoma (HNSCC). On the basis of our preclinical data demonstrating that phosphodiesterase-5 (PDE5) inhibition can modulate these cell populations, we evaluated whether the PDE5 inhibitor tadalafil can revert tumor-induced immunosuppression and promote tumor immunity in patients with HNSCC. Experimental Design First, we functionally and phenotypically characterized MDSCs in HNSCCs and determined, retrospectively, whether their presence at the tumor site correlates with recurrence. Then, we performed a prospective single-center, double-blinded, randomized, three-arm study in which patients with HNSCC undergoing definitive surgical resection of oral and oropharyngeal tumors were treated with tadalafil 10 μg/day, 20 μg/day, or placebo for at least 20 days preoperatively. Blood and tumor MDSC and Treg presence and CD8+ T-cell reactivity to tumor antigens were evaluated before and after treatment. Results MDSCs were characterized in HNSCC and their intratumoral presence significantly correlates with recurrence. Tadalafil treatment was well tolerated and significantly reduced both MDSCs and Treg concentrations in the blood and in the tumor (P < 0.05). In addition, the concentration of blood CD8+ T cells reactive to autologous tumor antigens significantly increased after treatment (P < 0.05). Tadalafil immunomodulatory activity was maximized at an intermediate dose but not at higher doses. Mechanistic analysis suggests a possible off-target effect on PDE11 at high dosages that, by increasing intracellular cAMP, may negatively affect antitumor immunity. Conclusions Tadalafil seems to beneficially modulate the tumor micro- and macro-environment in patients with HNSCC by lowering MDSCs and Tregs and increasing tumor-specific CD8+ T cells in a dose-dependent fashion.

Purpose: To assess, through a retrospective review, clinical outcomes of patients with squamous cell carcinoma of the tonsil treated at the M. D. Anderson Cancer Center with unilateral radiotherapy techniques that irradiate the involved tonsil region and ipsilateral neck only. Methods and Materials: Of 901 patients with newly diagnosed squamous cell carcinoma of the tonsil treated with radiotherapy at our institution, we identified 102 that were treated using unilateral radiotherapy techniques. All patients had their primary site of disease restricted to the tonsillar fossa or anterior pillar, with <1 cm involvement of the soft palate. Patients had TX (n =more » 17 patients), T1 (n = 52), or T2 (n = 33) disease, with Nx (n = 3), N0 (n = 33), N1 (n = 23), N2a (n = 21), or N2b (n = 22) neck disease. Results: Sixty-one patients (60%) underwent diagnostic tonsillectomy before radiotherapy. Twenty-seven patients (26%) underwent excision of a cervical lymph node or neck dissection before radiotherapy. Median follow-up for surviving patients was 38 months. Locoregional control at the primary site and ipsilateral neck was 100%. Two patients experienced contralateral nodal recurrence (2%). The 5-year overall survival and disease-free survival rates were 95% and 96%, respectively. The 5-year freedom from contralateral nodal recurrence rate was 96%. Nine patients required feeding tubes during therapy. Of the 2 patients with contralateral recurrence, 1 experienced an isolated neck recurrence and was salvaged with contralateral neck dissection only and remains alive and free of disease. The other patient presented with a contralateral base of tongue tumor and involved cervical lymph node, which may have represented a second primary tumor, and died of disease. Conclusions: Unilateral radiotherapy for patients with TX-T2, N0-N2b primary tonsil carcinoma results in high rates of disease control, with low rates of contralateral nodal failure and a low incidence of acute toxicity requiring gastrostomy.« less

To examine outcomes of selective neck dissection (SND) in patients with human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) who present with clinical neck disease. Multi-institutional retrospective review. Two institutional databases of patients with HPV-related OPSCC were reviewed to identify patients with clinical (c) N1-N3 neck disease who underwent SND ± adjuvant therapy. Three hundred and twenty-four patients were identified with a median follow-up of 49 months (range 3-199 months). All patients underwent transoral resection of the primary tumor and SND, including levels II-IV and ± levels I or V, with resection of additional nonlymphatic tissue (extended SND) as indicated by extent of disease, including the spinal accessory nerve (7%), the internal jugular vein (13%), and the sternocleidomastoid muscle (8%). Two hundred and seventy (83%) patients underwent adjuvant radiation. There were 13 (4%) regional recurrences and 19 (6%) distant recurrences. Regional control following salvage was 98%. On univariable analysis, absence of radiation was associated with regional recurrence (odds ratio [OR] 9.2, 95% confidence interval [CI] 2.9-29.4). On multivariable analysis, adjuvant radiation was associated with improved disease-free survival (DFS) (OR 0.27, 95% CI 0.14-0.53) but lost significance for overall (OS) and disease-specific survival (DSS) (P > 0.05). Five-year Kaplan-Meier estimates for OS, DSS, and DFS were 88% (95% CI 84%-92%), 93% (95% CI 89%-96%), and 83% (95% CI 78%-87%), respectively. In HPV-related OPSCC presenting with clinical neck disease, a SND ± additional tissue resection and adjuvant therapy, when indicated, provides excellent long-term regional control. Omission of radiotherapy increases the risk of regional recurrence, although it may not significantly impact OS or DSS. It appears unnecessary to routinely perform a comprehensive neck dissection. 4.

Purpose: To report outcomes of the rare disease of squamous cell carcinoma (SCC) of the external auditory canal (EAC) and middle ear treated with surgery and postoperative intensity-modulated radiotherapy (IMRT). Failure patterns related to spatial dose distribution were also analyzed to provide insight into target delineation. Methods and Materials: A retrospective review was conducted of the records of 11 consecutive patients with SCC of the EAC and middle ear who were treated with curative surgery and postoperative IMRT at one institution between January 2007 and February 2010. The prescribed IMRT dose was 60 to 66 Gy at 2 Gy permore » fraction. Three patients also received concurrent cisplatin-based chemotherapy, and 1 patient received concurrent oral tegafur/uracil. The median follow-up time was 19 months (range, 6-33 months). Results: Four patients had locoregional recurrence, yielding an estimated 2-year locoregional control rate of 70.7%. Among them, 1 patient had persistent disease after treatment, and 3 had marginal recurrence. Distant metastasis occurred in 1 patient after extensive locoregional recurrence, yielding an estimated 2-year distant control rate of 85.7%. The estimated 2-year overall survival was 67.5%. The three cases of marginal recurrence were near the preauricular space and glenoid fossa of the temporomandibular joint, adjacent to the apex of the ear canal and glenoid fossa of the temporomandibular joint, and in the postauricular subcutaneous area and ipsilateral parotid nodes, respectively. Conclusions: Marginal misses should be recognized to improve target delineation. When treating SCC of the EAC and middle ear, care should be taken to cover the glenoid fossa of the temporomandibular joint and periauricular soft tissue. Elective ipsilateral parotid irradiation should be considered. The treatment planning procedure should also be refined to balance subcutaneous soft-tissue dosimetry and toxicity.« less

To determine the diagnostic performance of FDG-PET/MRI with diffusion-weighted imaging (FDG-PET/DWIMRI) for detection and local staging of head and neck squamous cell carcinoma (HNSCC) after radio(chemo)therapy. This was a prospective study that included 74 consecutive patients with previous radio(chemo)therapy for HNSCC and in whom tumour recurrence or radiation-induced complications were suspected clinically. The patients underwent hybrid PET/MRI examinations with morphological MRI, DWI and FDG-PET. Experienced readers blinded to clinical/histopathological data evaluated images according to established diagnostic criteria taking into account the complementarity of multiparametric information. The standard of reference was histopathology with whole-organ sections and follow-up ≥24 months. Statistical analysis considered data clustering. The proof of diagnosis was histology in 46/74 (62.2%) patients and follow-up (mean ± SD = 34 ± 8 months) in 28/74 (37.8%). Thirty-eight patients had 43 HNSCCs and 46 patients (10 with and 36 without tumours) had 62 benign lesions/complications. Sensitivity, specificity, and positive and negative predictive value of PET/DWIMRI were 97.4%, 91.7%, 92.5% and 97.1% per patient, and 93.0%, 93.5%, 90.9%, and 95.1% per lesion, respectively. Agreement between imaging-based and pathological T-stage was excellent (kappa = 0.84, p < 0.001). FDG-PET/DWIMRI yields excellent results for detection and T-classification of HNSCC after radio(chemo)therapy. • FDG-PET/DWIMRI yields excellent results for the detection of post-radio(chemo)therapy HNSCC recurrence. • Prospective one-centre study showed excellent agreement between imaging-based and pathological T-stage. • 97.5% of positive concordant MRI, DWI and FDG-PET results correspond to recurrence. • 87% of discordant MRI, DWI and FDG-PET results correspond to benign lesions. • Multiparametric FDG-PET/DWIMRI facilitates planning of salvage surgery in the irradiated neck.

Intensity-modulated radiotherapy (IMRT) is considered the preferred option in squamous cell canal cancer (SCAC), delivering high doses to tumor volumes while minimizing dose to surrounding normal tissues. IMRT has steep dose gradients, but the technique is more demanding as deep understanding of target structures is required. To evaluate genital marginal failure in a cohort of patients with non-metastatic SCAC treated either with IMRT or 3DCRT and concurrent chemotherapy, 117 patients with SCAC were evaluated: 64 and 53 patients were treated with IMRT and 3DCRT techniques, respectively. All patients underwent clinical and radiological examination during their follow-up. Tumor response was evaluated with response evaluation criteria in solid tumors v1.1 guideline on regular basis. All patients' data were analyzed, and patients with marginal failure were identified. Concomitant chemotherapy was administered in 97 and 77.4% of patients in the IMRT and 3DCRT groups, respectively. In the IMRT group, the median follow-up was 25 months (range 6-78). Progressive disease was registered in 15.6% of patients; infield recurrence, distant recurrence and both infield recurrence and distant recurrence were identified in 5, 4 and 1 patient, respectively. Two out of 64 patients (3.1%) had marginal failures, localized at vagina/recto-vaginal septum and left perineal region. In the 3DCRT group, the median follow-up was 71.3 months (range 6-194 months). Two out of 53 patients (3.8%) had marginal failures, localized at recto-vaginal septum and perigenital structures. The rate of marginal failures was comparable in IMRT and 3DCRT groups (χ 2 test p = 0.85). In this series, the use of IMRT for the treatment of SCAC did not increase the rate of marginal failures offering improved dose conformity to the target. Dose constraints should be applied with caution-particularly in females with involvement of the vagina or the vaginal septum.

Despite improvements in functional outcomes attributable to advances in radiotherapy, chemotherapy, surgical techniques, and imaging techniques, survival in head and neck squamous cell carcinoma (HNSCC) patients has improved only marginally during the last couple of decades, and optimal therapy has yet to be devised. Genomic complexity and intratumoral genetic heterogeneity may contribute to treatment resistance and the propensity for locoregional recurrence. Countering this, demands a significant effort from both basic and clinical scientists in the search for more-effective targeted therapies. Recent genomewide studies have provided valuable insights into the genetic basis of HNSCC, uncovering potential new therapeutic opportunities. In addition, several studies have elucidated how inflammatory, immune, and stromal cells contribute to the particular properties of these neoplasms. In the present review, we introduce recent findings on genomic aberrations resulting from whole-genome sequencing of HNSCC, we discuss how the particular microenvironment affects the pathogenesis of this disease, and we describe clinical trials exploring new perspectives on the use of combined genetic and cellular targeted therapies.

Two Unusual Cases of Oral Lichen Planus Arising After Oral Squamous Cell Carcinoma: Can Oral Cancer Trigger Autoimmunity?

PubMed

Gissi, Davide Bartolomeo; Asioli, Sofia; Gabusi, Andrea

2017-08-01

Autoimmune diseases occur when the immune system fails to recognize self-antigens expressed on the body's own cells and attacks them. Oral lichen planus (OLP) is a chronic autoimmune mucocutaneous disease of the oral cavity characterized by white/red lesions. Considered a potentially malignant disorder, OLP evolution into oral squamous cell carcinoma (OSCC) is still a matter of debate. While chronic autoimmune inflammation is considered a potential risk factor for malignant transformation in many solid tumors, the opposite idea that cancer may trigger autoimmune responses remains controversial. We describe 2 patients who developed lesions clinically suggestive of OLP with histological evidence of lichenoid infiltration some time after OSCC removal, even in areas far from the neoplastic site. Neither patient had OLP before the diagnosis of OSCC, or reported exposure to OLP-associated etiologic factors, and neither. experienced tumor recurrence during follow-up. Our findings suggest that oral cancer remission may be linked to OLP development, but further studies are necessary to unveil the underlying mechanisms and possible prognostic implications.

Discussion of current strategies targeting the immune system related to solid tumors with emphasis on head and neck squamous cell carcinoma (HNSCC).This review will outline the current challenges with immunotherapy and future goals for treatment using these agents. Agents targeting immune checkpoint receptors (IR) such as program death 1 (PD1) have been used in the clinical realm for melanoma and non-small cell lung cancer (NSCLC), and the use of these agents for these malignancies has provided crucial information about how and why patients respond or not to inhibitory checkpoint receptor blockade therapy (ICR). The anti PD1 agent, nivolumab, was recently approved by the FDA as a standard of care regimen for patients with platinum refractory recurrent/metastatic (R/M) HNSCC. Molecular pathways leading to resistance are starting to be identified, and work is underway to understand the most optimal treatment regimen with incorporation of immunotherapy. ICR has renewed interest in the immunology of cancer, but resistance is not uncommon, and thus understanding of these mechanisms will allow the clinician to appropriately select patients that will benefit from this therapy.

To analyze the superiority of wait-and-see policy and elective neck dissection in treating cN0 patients with facial cutaneous cell carcinoma (cSCC).Patients with clinically negative parotid and neck metastasis disease were prospectively enrolled. Three groups were divided based on whether the patient received an operation of superficial parotidectomy or/and elective dissection, and regional control and disease-specific survival rates were compared.The occult parotid and neck metastasis rate was 20% and 16%, respectively. There was neck node metastasis without parotid metastasis in only 1 patient. All the node metastasis occurred in level II. Regional recurrence was noted in 16 (16%) patients, and 6 patients died of the disease. In the group undergoing superficial parotidectomy and elective neck dissection, 2 patients had neck node metastasis, and there was no disease-related death, further survival analysis indicated it had better regional control and disease-specific survival rates compared with the other 2 groups.Superficial parotidectomy and elective neck dissection are suggested for patients with T3-4 facial cutaneous squamous cell carcinoma.

Background Recurrent head and neck squamous cell carcinoma (HNSCC) remains a difficult cancer to treat. Here, we describe a patient with HNSCC who had complete response to methotrexate (MTX) after progressing on multiple cytotoxic agents, cetuximab, and AMG-479 (monoclonal antibody against insulin-like growth factor-1 receptor [IGF-1R]). Methods The clinical information was collected by a retrospective medical record review under an Institutional Review Board–approved protocol. From 4 tumors and 2 normal mucosal epithelia, global gene expression, and IGF-1R and dihydrofolate reductase (DHFR) protein levels were determined. Results Effective target inhibition in the tumor was confirmed by the decreased protein levels of total and phospho-IGF-1R after treatment with AMG-479. Decreased level of DHFR and conversion of a gene expression profile associated with cetuximab-resistance to cetuximab-sensitivity were also observed. Conclusion This suggests that the combination of AMG- 479 and MTX or cetuximab may be a promising therapeutic approach in refractory HNSCC. PMID:20652976

Squamous cell carcinomas (SCCs) of the external ear have a significant rate of metastasis. The purpose of this study was to present analyzed factors associated with auricular SCC metastasis in order to identify a group that may benefit from sentinel lymph node biopsy (SLNB). We performed a retrospective review of all operable SCCs between 2009 and 2014. The association between high-risk features and metastasis were analyzed. One hundred eighty-nine auricular SCCs were excised. Local recurrence was noted in 11% and 9.5% developed metastases. Cartilage, perineural, and lymphovascular invasion were significantly associated with metastasis, as were increased tumor depth and diameter (P < .001). All patients with metastasis developed nodal disease. Factors, including poor differentiation, perineural, cartilage, and lymphovascular invasion, are associated with auricular SCC metastasis. Patients with 2 or more high-risk features may benefit from SLNB in order to identify and treat early nodal disease and possibly reduce the risk of further spread. © 2017 Wiley Periodicals, Inc.

Orocutaneous fistula sometimes occurs in locallyadvanced unresectable or recurrent oral squamous cell carcinoma. The developed orocutaneous fistula results in constant leakage of saliva, ingested foods and liquids and decline in patients' quality of life(QOL). A 47-year-old Japanese man had received treatment for tongue carcinoma. At the routine follow-up, a cystic lesion in the right submandibular region was detected. Biopsyof the specimen of the cystic lesion revealed squamous cell carcinoma. After chemotherapy, an orocutaneous fistula between the right oropharyngeal and the right submandibular region developed and graduallyincreased. Although closure and dressing of the orocutaneous fistula with various materials was attempted, it was ultimatelyunsuccessful. Finally, application of a rubber film and silicone adhesive agent to the skin was successful for closure and dressing of the fistula. Orocutaneous fistula is one of major contributors to decline in patients' QOL. The sharing of information regarding effective methods or materials for closure and dressing of orocutaneous fistula is necessaryto maintain patients' QOL.

Definitive chemoradiotherapy (CRT) remains the most commonly used treatment for locally advanced esophageal squamous cell carcinoma (SCC), because of perceptions that esophagectomy offers an unclear survival advantage. We compare recurrence, overall survival (OS), and disease-free survival (DFS) in patients treated with definitive CRT or neoadjuvant CRT followed by surgery (trimodality). This was a retrospective cohort study of patients with stage II and III SCC of the middle and distal esophagus in patients who completed CRT. Treatment groups were matched (1:1) on covariates using a propensity score-matching approach. The effect of trimodality treatment, compared with definitive CRT, on OS, DFS, and site-specific recurrence was evaluated as a time-dependent variable and analyzed using Cox regression with a gamma frailty term for matched units. We included 232 patients treated between 2000 and 2016: 124 (53%) with definitive CRT and 108 (47%) with trimodality. Trimodality was used less frequently over time (61% before 2009 and 29% after 2009; P < .0001). After matching, each group contained 56 patients. Median OS and DFS were 3.1 and 1.8 years for trimodality versus 2.3 and 1.0 years for CRT. Surgery was independently associated with improved OS (hazard ratio, 0.57; 95% confidence interval, 0.34-0.97; P = .039) and DFS (hazard ratio, 0.51; 95% confidence interval, 0.32-0.83; P = .007). CRT followed by surgery might decrease local recurrence and increase DFS and OS in patients with esophageal SCC. Until better tools to select patients with pathological complete response are available, surgery should remain an integral component of the treatment of locally advanced esophageal SCC.

To investigate the clinical usefulness of transoral bisected resection (TBR) asa new method to secure adequate deep resection margin in T1-2 oral tongue squamous cell carcinomas (SCC). Among 75 patients with cT1-2N0 oral tongue SCCs, 45 (60%) received transoral en-bloc resection (TER) while 30 (40%) received patients underwent TBR. Primary tumor resection was performed with 1.5-cm surgical resection margin for both groups. Mucosal and deep resection margins, adjuvant treatments including re-resection of the tongue and cheomoradiotherapy, local and regional recurrence free survival, and overall survival were compared between the two groups. Mean deep resection margin in the TBR group was 9.9mm (95% CI: 8.4-11.4mm), which was significantly (P<0.001) wider than that of the TER group (mean: 5.4mm, 95% CI: 4.5-6.3mm). However, mucosal resection margins were not significantly (P=0.153) different between the two groups. Re-resection of tongue was performed for 6 (13.3%) of 17 (37.8%) patients with inadequate deep resection margin in the TER group and none (0%) in 4 (13.3%) patients with inadequate deep resection margin in the TBR group. Adjuvant radiation due to inadequate deep resection margin was performed for 6.7% of patients in both groups. The TBR group had better local recurrence free survival than the TER group. However, regional recurrence free survival and overall survival were not significantly different between the two groups. TBR could provide adequate deep resection margin for early stage tongue cancers with better local tumor control than TER. It can decrease the necessity of adjuvant treatment for re-resection of the tongue. Copyright © 2017 Elsevier Ltd. All rights reserved.

The purpose of this study was to assess the efficacy and safety of cetuximab plus platinum-based chemotherapy for patients specifically diagnosed with recurrent or metastatic oral squamous cell carcinoma (OSCC). We conducted a multicenter retrospective observational study of patients who underwent first-line cetuximab plus platinum-based chemotherapy between December 2012 and June 2015. 65 patients received weekly cetuximab (week 1, 400 mg/m 2 ; subsequent weeks, 250 mg/m 2 ) plus a maximum of six 3-weekly cycles of cisplatin (80 or 100 mg/m 2 , day 1) or carboplatin (at an area under the curve of 5 mg/mL/min as a 1-h intravenous infusion on day 1) and 5-fluorouracil (800 or 1000 mg/m 2 /day, days 1-4). Patients with stable disease who received cetuximab plus platinum-based chemotherapy continued to receive cetuximab until disease progression or unacceptable toxicities, whichever occurred first. The median follow-up was 10.5 (range 1.2-34.2) months. The best overall response and the disease control rates were 46.2 and 67.7%, respectively. The median overall survival and progression-free survival rates were 12.1 and 7.8 months, respectively. The most common grades 3-4 adverse events were skin rash (9.2%) followed by leukopenia (6.2%). None of the adverse events were fatal. The results of our multicenter retrospective study, which was the largest of its kind to date, suggest that first-line cetuximab plus platinum-based chemotherapy is suitable and well-tolerated for the systemic therapy of recurrent or metastatic OSCC.

Esophageal cancer is the sixth leading cause of cancer death worldwide, and patients who are treated with surgery alone, without neoadjuvant therapies, experience frequent relapses. Whether postoperative therapies could reduce the recurrence or improve overall survival is still controversial for these patients. The purpose of our review is to figure out the value of postoperative adjuvant therapy and address the disputes about target volume delineation according to published data. Based on the evidence of increased morbidity and disadvantages on patient survival caused by postoperative chemotherapy or radiotherapy (RT) alone provided by studies in the early 1990s, the use of postoperative adjuvant therapies in cases of esophageal squamous cell carcinoma has diminished substantially and has been replaced gradually by neoadjuvant chemoradiation. With advances in surgery and RT, accumulating evidence has recently rekindled interest in the delivery of postoperative RT or chemoradiotherapy in patients with stage T3/T4 or N1 (lymph node positive) carcinomas after radical surgery. However, due to complications with the standard radiation field, a nonconforming modified field has been adopted in most studies. Therefore, we analyze different field applications and provide suggestions on the optimization of the radiation field based on the major sites of relapse and the surgical non-clearance area. For upper and middle thoracic esophageal carcinomas, the bilateral supraclavicular and superior mediastinal areas remain common sites of recurrence and should be encompassed within the clinical target volume. In contrast, a consensus has yet to be reached regarding lower thoracic esophageal carcinomas; the “standard” clinical target volume is still recommended. Further studies of larger sample sizes should focus on different recurrence patterns, categorized by tumor locations, refined classifications, and differing molecular biology, to provide more information on the delineation of target volumes.

To compare and contrast the patterns of failure in patients with locally advanced squamous cell oropharyngeal cancers undergoing curative-intent treatment with primary surgery or radiotherapy +/- chemotherapy. Two hundred and thirty-three patients with stage III or IV oropharyngeal squamous cell carcinoma who underwent curative-intent treatment from 2006-2012, were reviewed. The median length of follow-up for patients still alive at the time of analysis was 4.4 years. Data was collected retrospectively from a chart review. One hundred and thirty-nine patients underwent primary surgery +/- adjuvant therapy, and 94 patients underwent primary radiotherapy +/- chemotherapy (CRT). Demographics were similar between the two groups, except primary radiotherapy patients had a higher age-adjusted Charleston co-morbidity score (CCI). Twenty-nine patients from the surgery group recurred; 15 failed distantly only, seven failed locoregionally, and seven failed both distantly and locoregionally. Twelve patients recurred who underwent chemoradiotherapy; ten distantly alone, and two locoregionally. One patient who underwent radiotherapy (RT) alone failed distantly. Two and five-year recurrence-free survival rates for patients undergoing primary RT were 86.6% and 84.9% respectively. Two and five-year recurrence-free survival rates for primary surgery was 80.9% and 76.3% respectively (p=0.21). There was no significant difference in either treatment when they were stratified by p16 status or smoking status. Our analysis does not show any difference in outcomes for patients treated with primary surgery or radiotherapy. Although the primary pattern of failure in both groups was distant metastatic disease, some local failures may be preventable with careful delineation of target volumes, especially near the base of skull region.

To evaluate the surgical outcomes of ocular surface reconstruction in corneal-conjunctival tumors using fibrin tissue adhesive. A prospective noncomparative study was performed between May 2013 and February 2015. Patients were submitted to routine surgical procedure for corneal-conjunctival tumor excision followed by amniotic membrane graft transplantation using fibrin tissue adhesive (Evicel®, Omrix Biopharmaceuticals Ltd., Israel). Results were assessed on the 1st, 7th, 15th and 30th postoperative days to analyze subjective complaints, adhesiveness and positioning of the graft, potential complications and recurrences. Twenty-five eyes were analyzed (male, 14). The diagnosis after the treatment was categorized as squamous cell neoplasia, dysplasia, actinic keratosis, squamous papilloma and compound melanocytic nevus. Few significant symptoms were reported, such as mild hyperemia and ocular dyscomfort. One case developed a conjunctival granuloma which regressed after topical treatment. All grafts were successful with no displacements or retraction postoperatively. There was no clinical recurrence of the tumor in a mean time of follow-up of 11 months. Fibrin tissue adhesive is safe and effective in the surgery of ocular surface tumor. In this series, sutureless amniotic membrane transplantation using fibrin glue has the potential to shorten the surgical time, mitigate inflammation postoperatively and improve patient discomfort.

Purpose: Intrathoracic recurrence of non-small cell lung cancer (NSCLC) after initial treatment remains a dominant cause of death. We report our experience using proton beam therapy and intensity modulated radiation therapy for reirradiation in such cases, focusing on patterns of failure, criteria for patient selection, and predictors of toxicity. Methods and Materials: A total of 102 patients underwent reirradiation for intrathoracic recurrent NSCLC at a single institution. All doses were recalculated to an equivalent dose in 2-Gy fractions (EQD2). All patients had received radiation therapy for NSCLC (median initial dose of 70 EQD2 Gy), with median interval to reirradiation ofmore » 17 months and median reirradiation dose of 60.48 EQD2 Gy. Median follow-up time was 6.5 months (range, 0-72 months). Results: Ninety-nine patients (97%) completed reirradiation. Median local failure-free survival, distant metastasis-free survival (DMFS), and overall survival times were 11.43 months (range, 8.6-22.66 months), 11.43 months (range, 6.83-23.84 months), and 14.71 (range, 10.34-20.56 months), respectively. Toxicity was acceptable, with rates of grade ≥3 esophageal toxicity of 7% and grade ≥3 pulmonary toxicity of 10%. Of the patients who developed local failure after reirradiation, 88% had failure in either the original or the reirradiation field. Poor local control was associated with T4 disease, squamous histology, and Eastern Cooperative Oncology Group performance status score >1. Concurrent chemotherapy improved DMFS, but T4 disease was associated with poor DMFS. Higher T status, Eastern Cooperative Oncology Group performance status ≥1, squamous histology, and larger reirradiation target volumes led to worse overall survival; receipt of concurrent chemotherapy and higher EQD2 were associated with improved OS. Conclusions: Intensity modulated radiation therapy and proton beam therapy are options for treating recurrent non-small cell lung cancer. However, rates of locoregional recurrence and distant metastasis are high, and patients should be selected carefully to maximize the benefit of additional aggressive local therapy while minimizing the risk of adverse side effects.« less

The optimal regimen of chemotherapy and reirradiation (re-XRT) for recurrent head and neck squamous cell carcinoma (HNSCC) is controversial. We report the final outcomes of a multicenter phase II trial evaluating cetuximab and cisplatin-based chemotherapy concurrent with re-XRT for patients with recurrent HNSCC. Patients with unresectable recurrent disease or positive margins after salvage surgery arising within a previously irradiated field with KPS ≥ 70 were eligible for this trial. Cetuximab 400 mg/m2 was delivered as a loading dose in week 1 followed by weekly cetuximab 250 mg/m2 and cisplatin 30 mg/m2 concurrent with 6 weeks of intensity-modulated radiotherapy to a dose of 60-66 Gy in 30 daily fractions. Patients who previously received both concurrent cetuximab and cisplatin with radiation or who received radiotherapy less than 6 months prior were ineligible. From 2009 to 2013, 48 patients enrolled on this trial, 2 did not receive any protocol treatment. Of the remaining 46 patients, 34 were male and 12 female, with a median age of 62 years (range 36-85). Treatment was feasible and only 1 patient did not complete the treatment course. Common grade 3 or higher acute toxicities were lymphopenia (46%), pain (22%), dysphagia (13%), radiation dermatitis (13%), mucositis (11%) and anorexia (11%). There were no grade 5 acute toxicities. Eight grade 3 late toxicities were observed, four of which were swallowing related. With a median follow-up of 1.38 years, the 1-year overall survival (OS) was 60.4% and 1-year recurrence-free survival was 34.1%. On univariate analysis, OS was significantly improved with young age (P = 0.01). OS was not associated with radiation dose, surgery before re-XRT or interval from prior XRT. Concurrent cisplatin and cetuximab with re-XRT is feasible and offers good treatment outcomes for patients with high-risk features. Younger patients had significantly improved OS. NCT00833261.

2010-10-01

To predict the efficacy of cisplatin and radiation therapy for maxillary squamous cell carcinoma, we examined the mRNA expression of 14 cisplatin-resistant genes and p53 mutation in specimens biopsied from patients prior to initiation of therapy. Five of 10 patients had mutations in the p53 gene, of whom four had residual tumors pathologically following chemoradiotherapy (p=0.0476). Of 14 genes examined, the mRNA expression of ATP7B was significantly lower in cases that were resistant to chemoradiotherapy. Six genes including multidrug resistance protein 1 (MDR-1), multidrug resistance associated protein 1 (MRP-1), Cu++ transporting, beta polypeptide (ATP7B), xeroderma pigmentosum, complementation group A (XPA), excision repair cross-complementing rodent repair deficiency, complementation group 1 (ERCC-1) and B-cell CLL/lymphoma 2 (BCL2) were down-regulated in cases of recurrent cancers. These results show that the evaluation of p53 mutation provides the most useful predictor of therapeutic effects. In responder cases, the drug-resistant genes that were determined in cell lines by culture do not necessarily translate into clinical relevance.

Proliferative verrucous leukoplakia (PVL) is an aggressive form of oral leukoplakia that is persistent, often multifocal, and refractory to treatment with a high risk of recurrence and malignant transformation. This article describes the clinical aspects and histologic features of a case that demonstrated the typical behavior pattern in a long-standing, persistent lesion of PVL of the mandibular gingiva and that ultimately developed into squamous cell carcinoma. Prognosis is poor for this seemingly harmless-appearing white lesion of the oral mucosa.

Nivolumab significantly improved overall survival (OS) vs investigator's choice (IC) of chemotherapy at the primary analysis of randomized, open-label, phase 3 CheckMate 141 in patients with recurrent or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN). Here, we report that OS benefit with nivolumab was maintained at a minimum follow-up of 11.4 months. Further, OS benefit with nivolumab vs IC was also noted among patients who received first-line treatment for R/M SCCHN after progressing on platinum therapy for locally advanced disease in the adjuvant or primary (i.e., with radiation) setting.

Data on the treatment of non-small cell lung cancer (NSCLC) in real-world clinical practice in Japan are limited. This large-scale, retrospective cohort study examined data on patients' characteristics and systemic therapies for advanced or recurrent NSCLC in routine practice in Japan. This study used an electronic health records-based database of health claims and Diagnosis Procedure Combination data from 215 consenting hospitals in Japan. Records from April 2008 to September 2015 were analyzed. Regimens were examined by histology, age, sex, and therapeutic line. Logistic regression analysis was performed to predict which clinical and demographic factors affected patients' probability of receiving first- or second-line therapy or completing first-line platinum-based chemotherapy. Among 16,413 patients, 67.9%, 39.2%, and 22.3% received first-, second-, and third-line systemic treatment, respectively. Treatment was more common in patients aged <75 versus ≥75 years (76.0% vs 51.6%), in female versus male patients (71.6% vs 65.4%), and in patients with nonsquamous versus squamous disease (75.6% vs 61.9%). More than 30 systemic regimens were administered. The most common first-line therapy was platinum-based chemotherapy (nonsquamous, 53.6%; squamous, 73.7%). Non-platinum-based chemotherapy use increased in the second-line setting, but platinum-based chemotherapy use remained high (nonsquamous, 33.9%; squamous, 38.6%). Tyrosine kinase inhibitors were used in 32.0% and 29.4% of patients with nonsquamous NSCLC in the first- and second-line settings, respectively. Switches from first- to second-line platinum-based chemotherapy and from first- to second-line tyrosine kinase inhibitors occurred. Forty-two percent of the patients died during hospitalization. In the logistic regression analysis, factors associated with a decreased likelihood of receiving first-line therapy were male sex, squamous histology, age >75 years, treatment at a general (vs cancer-specific) hospital, worse scores on certain activities of daily living, presence of chronic pulmonary disease, worse Hugh-Jones classification, and positive smoking status. The likelihood of completing first-line platinum-based chemotherapy was increased with greater body mass index, better activities of daily living scores, absence of chronic pulmonary disease, and better Hugh-Jones classification. The likelihood of continuing with second-line therapy was decreased with older age and recurrence of NSCLC. Systemic treatment patterns for advanced or recurrent NSCLC in Japan were varied. Nearly 30% of all patients and approximately half of elderly patients did not receive systemic treatment. Treatment rates declined with subsequent therapeutic lines. Generally, guidelines were followed with first-line treatment administration, but not with second-line administration. These results underscore the need for better guideline adherence and more optimal treatment in and elderly patients and in those receiving later-line treatment in Japan. Copyright © 2017 The Authors.

We investigated the prognostic role of tumour-associated macrophages (TAMs) in patients with head and neck squamous cell carcinoma (HNSCC) treated with definitive chemoradiotherapy (CRT). The expression of CD68+, CD163+ and CD11b+ cells was assessed using immunohistochemistry in n=106 pre-treatment tumour biopsy samples and was correlated with clinicopathological characteristics, including T-stage, N-stage, grading, tumour localisation, age and sex as well as local failure-free survival (LFFS), distant metastases-free survival (DMFS), progression-free (PFS), and overall survival (OS). Finally, TAMs expression and vessel density (CD31) were examined in n=12 available early local recurrence samples and compared with their matched primary tumours . The diagnostic images and radiotherapy plans of these 12 patients were also analysed. All local recurrences occurred in the high radiation dose region (⩾70 Gy). With a median follow-up of 40 months, OS at 2 years was 60.5%. High CD163 expression in primary tumours was associated with decreased OS (P=0.010), PFS (P=0.033), LFFS (P=0.036) and DMFS (P=0.038) in multivariate analysis. CD163 demonstrated a strong prognostic value only in human papillomavirus (p16(INK4))-negative patients. Early local recurrence specimens demonstrated a significantly increased infiltration of CD11b+ myeloid cells (P=0.0097) but decreased CD31-positive vessel density (P=0.0004) compared with their matched primary samples. Altogether, baseline CD163 expression predicts for an unfavourable clinical outcome in HNSCC after definitive CRT. Early local recurrences showed increased infiltration by CD11b+ cells. These data provide important insight on the role of TAMs in mediating response to CRT in patients with HNSCC.

Atypical squamous cells in the urine revealing endometrioid adenocarcinoma of the endometrium with squamous cell differentiation: a case report.

Urine cytology is mainly used to detect urothelial carcinoma (UC), especially for high-grade lesions including urothelial carcinoma in situ. Benign squamous cells are often seen in the urine specimens of women, they are either exfoliated from the trigone area of the bladder, the urethra, or the cervicovaginal region. However, abnormal squamous cells in the urine raise concerns of abnormalities of the urinary tract and cervicovaginal area which range from squamous metaplasia of the urothelium, a cervicovaginal squamous intraepithelial lesion, condyloma acuminatum of the bladder, UC with squamous differentiation, and squamous cell carcinoma. We present here a unique case of atypical squamous cells (ASCs) in the urine subsequently leading to the diagnosis of endometrioid adenocarcinoma of the endometrium with squamous differentiation. The presence of ASCs in voided urine is a rare finding that may indicate an underlying malignancy. Careful evaluation of squamous cells in the urine is an important part of our daily cytopathology practice. © 2014 Wiley Periodicals, Inc.

Most previously described immunohistochemical markers of cervical high-grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma may help to improve diagnostic accuracy but have a minimal prognostic value. The goals of the current study were to identify and validate novel candidate biomarkers that could potentially improve diagnostic and prognostic accuracy for cervical HSIL and squamous cell carcinoma. Microdissected tissue sections from formalin-fixed paraffin-embedded normal ectocervical squamous mucosa, low-grade squamous intraepithelial lesion (LSIL), HSIL and squamous cell carcinoma sections were analyzed by mass spectrometry-based shotgun proteomics for biomarker discovery. The diagnostic specificity of candidate biomarkers was subsequently evaluated by immunohistochemical analysis of tissue microarrays. Among 1750 proteins identified by proteomic analyses, keratin 4 (KRT4) and keratin 17 (KRT17) showed reciprocal patterns of expression in the spectrum of cases ranging from normal ectocervical squamous mucosa to squamous cell carcinoma. Immunohistochemical studies confirmed that KRT4 expression was significantly decreased in squamous cell carcinoma compared with the other diagnostic categories. By contrast, KRT17 expression was significantly increased in HSIL and squamous cell carcinoma compared with normal ectocervical squamous mucosa and LSIL. KRT17 was also highly expressed in immature squamous metaplasia and in endocervical reserve cells but was generally not detected in mature squamous metaplasia. Furthermore, high levels of KRT17 expression were significantly associated with poor survival of squamous cell carcinoma patients (Hazard ratio = 14.76, P = 0.01). In summary, both KRT4 and KRT17 expressions are related to the histopathology of the cervical squamous mucosa; KRT17 is highly overexpressed in immature squamous metaplasia, in HSIL, and in squamous cell carcinoma and the level of KRT17 in squamous cell carcinoma may help to identify patients who are at greatest risk for cervical cancer mortality.

Orofacial pain impairs a patient's speech, swallowing, eating and interpersonal relations. Thirty-seven patients with a premalignant oral lesion, 124 patients with oral squamous cell carcinoma (OSSC), and 21 patients with a recurrence of OSSC were evaluated for their orofacial pain. The University of California San Francisco Oral Cancer Pain Questionnaire was administered to these patients at their initial visit, before they were prescribed analgesics for pain and before any treatment. Significant differences with respect to orofacial pain between the groups could be evaluatedwere observed. Patients with recurrence had the highest facial pain and patients with precancer had the lowest. Patients with OSSC and recurrence of OSSC reported significant levels of orofacial pain and functional restriction because of pain. Moreover, patients with recurrence of OSSC experienced significantly higher function-related pain, rather than pain qualities. These findings suggest that an important predictor for recurrence of OSSC may be the onset of orofacial pain that is exacerbated during function. The present study examined orofacial pain depending on the disease severity of precancer and oral cancer patients. Earlier recognition of symptoms of OSSC may improve early detection of its recurrence.

Treatment failure and poor 5-year survival in mucosal head and neck squamous cell carcinoma (HNSCC) has remained unchanged for decades mainly due to advanced stage of presentation and high rates of recurrence. Incomplete surgical removal of the tumour, attributed to lack of reliable methods to delineate the surgical margins, is a major cause of disease recurrence. The predictability of recurrence using immunohistochemistry (IHC) to delineate surgical margins (PRISM) in mucosal HNSCC study aims to redefine margin status by identifying the true extent of the tumour at the molecular level by performing IHC with molecular markers, eukaryotic initiation factor, eIF4Eand tumour suppressor gene, p53, on the surgical margins and test the use of Lugol's iodine and fluorescence visualisation prior to the wide local excision. This article describes the study protocol at its pre - results stage. PRISM-HNSCC is a bilateral observational research being conducted in Darwin, Australia and Vellore, India. Individuals diagnosed with HNSCC will undergo the routine wide local excision of the tumour followed by histopathological assessment. Tumours with clear surgical margins that satisfy the exclusion criteria will be selected for further staining of the margins with eIF4E and p53 antibodies. Results of IHC staining will be correlated with recurrences in an attempt to predict the risk of disease recurrence. Patients in Darwin will undergo intraoperative staining of the lesion with Lugol's iodine and fluorescence visualisation to delineate the excision margins while patients in Vellore will not undertake these tests. The outcomes will be analysed. The PRISM-HNSCC study was approved by the institutional ethics committees in Darwin (Human Research Ethics Committee 13-2036) and Vellore (Institutional Review Board Min. no. 8967). Outcomes will be disseminated through publications in academic journals and presentations at educational meetings and conferences.

Objectives Treatment failure and poor 5-year survival in mucosal head and neck squamous cell carcinoma (HNSCC) has remained unchanged for decades mainly due to advanced stage of presentation and high rates of recurrence. Incomplete surgical removal of the tumour, attributed to lack of reliable methods to delineate the surgical margins, is a major cause of disease recurrence. The predictability of recurrence using immunohistochemistry (IHC) to delineate surgical margins (PRISM) in mucosal HNSCC study aims to redefine margin status by identifying the true extent of the tumour at the molecular level by performing IHC with molecular markers, eukaryotic initiation factor, eIF4Eand tumour suppressor gene, p53, on the surgical margins and test the use of Lugol’s iodine and fluorescence visualisation prior to the wide local excision. This article describes the study protocol at its pre - results stage. Methods and analysis PRISM-HNSCC is a bilateral observational research being conducted in Darwin, Australia and Vellore, India. Individuals diagnosed with HNSCC will undergo the routine wide local excision of the tumour followed by histopathological assessment. Tumours with clear surgical margins that satisfy the exclusion criteria will be selected for further staining of the margins with eIF4E and p53 antibodies. Results of IHC staining will be correlated with recurrences in an attempt to predict the risk of disease recurrence. Patients in Darwin will undergo intraoperative staining of the lesion with Lugol’s iodine and fluorescence visualisation to delineate the excision margins while patients in Vellore will not undertake these tests. The outcomes will be analysed. Ethics and dissemination The PRISM-HNSCC study was approved by the institutional ethics committees in Darwin (Human Research Ethics Committee 13-2036) and Vellore (Institutional Review Board Min. no. 8967). Outcomes will be disseminated through publications in academic journals and presentations at educational meetings and conferences. It will be presented as dissertation at the Charles Darwin University. We will communicate the study results to both participating sites. Participating sites will communicate results with patients who have indicated an interest in knowing the results.

Purpose: There are limited therapeutic options for patients with recurrent head and neck cancer after radiation therapy failure. To assess the use of tumor necrosis factor–related apoptosis-inducing ligand (TRAIL) as a salvage chemotherapeutic agent for recurrent cancer after radiation failure, we investigated the effect of clinically relevant cumulative irradiation on TRAIL-induced apoptosis. Methods and Materials: Using a previously established HN3 cell line from a laryngeal carcinoma patient, we generated a chronically irradiated HN3R isogenic cell line. Viability and apoptosis in HN3 and HN3R cells treated with TRAIL were analyzed with MTS and PI/annexin V-FITC assays. Western blotting and flow cytometry weremore » used to determine the underlying mechanism of TRAIL resistance. DR4 expression was semiquantitatively scored in a tissue microarray with 107 laryngeal cancer specimens. Methylation-specific polymerase chain reaction and bisulfite sequencing for DR4 were performed for genomic DNA isolated from each cell line. Results: HN3R cells were more resistant than HN3 cells to TRAIL-induced apoptosis because of significantly reduced levels of the DR4 receptor. The DR4 staining score in 37 salvage surgical specimens after radiation failure was lower in 70 surgical specimens without radiation treatment (3.03 ± 2.75 vs 5.46 ± 3.30, respectively; P<.001). HN3R cells had a methylated DR4 CpG island that was partially demethylated by the DNA demethylating agent 5-aza-2′-deoxycytidine. Conclusion: Epigenetic silencing of the TRAIL receptor by hypermethylation of a DR4 CpG island might be an underlying mechanism for TRAIL resistance in recurrent laryngeal carcinoma treated with radiation.« less

A 70-year-old man presented with dysphagia to another institution and was referred to our hospital. We diagnosed the patient with primary neuroendocrine cell carcinoma and squamous cell carcinoma of the esophagus. Following 2 courses of CDDP+5-FU+ADM combination neoadjuvant chemotherapy, the primary tumor had reduced in size. Thereafter, we performed subtotal esophagectomy by right thoracotomy, retrosternal gastric tube reconstruction, and 2-field lymph node dissection. Computed tomography scan 3 months after the surgery revealed lung metastasis. He received CPT-11+CDDP chemotherapy, and the disease was diagnosed as cCR. At present, he is alive without any evidence of recurrence 12 months after the surgery.

Squamous cell carcinoma of the urinary bladder is unusual and of unknown etiology. There is a well-established association between human papillomavirus (HPV) infection and the development of cervical and head/neck squamous cell carcinomas. However, the role of HPV in the pathogenesis of squamous cell carcinoma of the urinary bladder is uncertain. The purposes of this study were to investigate the possible role of HPV in the development of squamous cell carcinoma of the urinary bladder and to determine if p16 expression could serve as a surrogate marker for HPV in this malignancy. In all, 42 cases of squamous cell carcinoma of the urinary bladder and 27 cases of urothelial carcinoma with squamous differentiation were investigated. HPV infection was analyzed by both in situ hybridization at the DNA level and immunohistochemistry at the protein level. p16 protein expression was analyzed by immunohistochemistry. HPV DNA and protein were not detected in 42 cases of squamous cell carcinoma (0%, 0/42) or 27 cases of urothelial carcinoma with squamous differentiation (0%, 0/15). p16 expression was detected in 13 cases (31%, 13/42) of squamous cell carcinoma and 9 cases (33%, 9/27) of urothelial carcinoma with squamous differentiation. There was no correlation between p16 expression and the presence of HPV infection in squamous cell carcinoma of the bladder or urothelial carcinoma with squamous differentiation. Our data suggest that HPV does not play a role in the development of squamous cell carcinoma of the urinary bladder or urothelial carcinoma with squamous differentiation. p16 expression should not be used as a surrogate marker for evidence of HVP infection in either squamous cell carcinoma of the urinary bladder or urothelial carcinoma with squamous differentiation as neither HVP DNA nor protein is detectable in these neoplasms.

Patients diagnosed with T3 squamous cell laryngeal carcinomas are nowadays offered either organ-preserving surgical or non-surgical treatment, with the optimum approach remaining undefined. No direct comparison of organ-preserving therapeutical options, stratified by anatomical subsites is available in the literature. The aim of this study is to present institutional treatment outcomes for laser-assisted microsurgery (TLM) of laryngeal T3 squamous cell carcinomas and review the relevant literature. Sixty-four consecutive, previously untreated patients were evaluated. Twenty-four supraglottic and 19 glottic patients were treated with TLM and neck dissection, tumor exposure and postoperative upstaging of the tumors through pathology evaluation of the specimens being the only exclusion criteria. Five-year disease-specific survival and organ preservation rates for supraglottic carcinomas were both 91.7 %. The respective values for glottic carcinomas were 63.2 and 73.3 %. TLM-treated T3 supraglottic tumors seem to attribute better outcomes than T3 glottic tumors in terms of recurrence-free survival, organ preservation and local control (p = 0.01, <0.0001 and 0.01, respectively). The results of this study suggest that TLM-treated T3 supraglottic tumors have a good prognosis, substantially better than that of glottic tumors. A literature review, on the other hand, attributes to chemo-radiation-treated T3 supraglottic tumors a considerably poorer prognosis. Further studies of homogenous populations in terms of anatomical subsites are needed in order to reach a consensus regarding treatment of T3 laryngeal tumors.

The main aim of the present report is to study the behavior of SCC of the floor of the mouth. A retrospective analysis was conducted using the records of patients diagnosed with squamous cell carcinoma of the floor of the mouth between 2000 and 2012 in the HUVN. Ninety-three patients with squamous cell carcinoma of the floor of the mouth treated with tumourectomy and selective neck dissection were included in the study. The pattern of distribution of cervical metastases and numerous histological features such as T-stage, N stage, surgical margins, tumor thickness, ECS (extracapsular spread) and vascular invasion were analyzed. Level I was the most affected level, followed by Level II. T stage, tumor thickness, and surgical margins showed a strong relationship with the risk of developing a local or cervical failure at follow-up. Overall survival was 52.7%. T stage, tumor thickness, N stage, recurrence, extracapsular spread, and vascular invasion were also associated with a poor prognosis. SCC of the floor of the mouth is an aggressive disease even at early stages. Due to the low rate of positive nodes observed at level IV and V in clinically N0 patients, supraomohyoid neck dissection might be considered sufficiently safe in this group.

Head and neck squamous cell carcinomas (HNSCCs) display cellular heterogeneity and contain cancer stem cells (CSCs). Sex-determining region Y [SRY]-box (SOX)2 is an important regulator of embryonic stem cell fate and is aberrantly expressed in several types of human tumours. Nonetheless, the role of SOX2 in HNSCC remains unclear. We created cells ectopically expressing SOX2 from previously established HNSCC cells and examined the cell proliferation, self-renewal capacity, and chemoresistance of these cells compared with control cells. In addition, we knocked down SOX2 in primary spheres obtained from HNSCC tumour tissue and assessed the attenuation of stemness-associated traits in these cells in vitro and in vivo. Furthermore, we examined the clinical relevance of SOX2 expression in HNSCC patients. SOX2 is aberrantly expressed in primary tissue of HNSCC patients but not in healthy tissue. SOX2 expression correlated with tumour recurrence and poor prognosis of HNSCC patients. Ectopic expression of SOX2 induced cell proliferation via cyclin B1 expression and stemness-associated features, such as self-renewal and chemoresistance. In addition, a knockdown of SOX2 in HNSCC CSCs attenuated their self-renewal capacity, chemoresistance (through ABCG2 suppression), invasion capacity (via snail downregulation), and in vivo tumorigenicity. These results suggest that SOX2 may have important roles in the 'stemness' and progression of HNSCC. Targeting SOX2-positive tumour cells (CSCs) could be a new therapeutic strategy in HNSCCs.

The management of 137 patients with carcinoma of the vulva is reported. The mean age at the onset of the disease of the patient was 64.1 yrs. Between 34 and 45% of the patients had diabetes. The predominant type of carcinoma was squamous cell carcinoma with the lesion originating from the labia. Metastases were found in eight patients. The value of lymphography in the management of carcinoma of the vulva is discussed. The 5 year survival rate was 24%. In the group of patients receiving radiotherapy alone, a high incidence of recurrence was observed. Following adequate surgery for carcinoma ofmore » the vulva, the incidence of recurrence was low. It is concluded that a mature carcinoma of the vulva cannot be cured by radiotherapy as the only modality. (auth)« less

Paracoccidioidomycosis is a disease that is endemic to southern and southeastern Brazil, caused by the fungus Paracoccidioides brasiliensis. The most common clinical oral manifestation is the presence of multiple granulomatous ulcers with hemorrhagic dots, located mainly on the lips, palate, and buccal mucosa. However, the disease can manifest atypically as a single ulcer, mimicking oral squamous cell carcinoma (SCC) or tuberculosis. A 65-year-old male patient presented with a complaint of a single ulcerated lesion on the dorsum of the tongue; the lesion had evolved over 6 months. The diagnostic hypotheses were SCC and oral manifestation of tuberculosis. An incisional biopsy was performed, and histopathological analysis of the specimen revealed pseudoepitheliomatous hyperplasia, a granulomatous structure of epithelioid histiocytes, multinucleated giant cells, and lymphocytes in the connective tissue. Grocott staining confirmed the presence of the fungus in the lesion, and a diagnosis was made of paracoccidioidomycosis. The patient was treated with 200 mg/day of itraconazole for 12 months and now shows no signs or symptoms of recurrence of the disease. Correct diagnosis is essential for a successful therapeutic approach and resolution of the lesion.

While human papillomavirus (HPV) is an accepted risk factor for oropharyngeal squamous cell carcinoma (SCC), its aetiological role in oral cavity SCC remains unclear. This study aimed to determine the HPV prevalence in an Australian population. DNA was extracted from 63 formalin-fixed paraffin-embedded tumour specimens histologically confirmed as SCC of the oral cavity, diagnosed during 2006-2012. Clinical data were extracted from medical records. HPV presence was determined by polymerase chain reaction. Positive samples were typed by sequencing. Immunohistochemistry was used to assess p16 INK4A , p53, pRB, Ki67, Cyclin D1 and p21 WAF1 expression. Five of the 63 tumours (8%) were positive for HPV DNA (three HPV-16 positive and two HPV-18 positive). Two tumours overexpressed p16 INK4A (3%) and one of these was also HPV positive. Overexpression of Cyclin D1 correlated significantly with tumour recurrence (P = 0.029) and death (P = 0.002). This study has identified a low prevalence of high-risk HPV in Queensland, Australia. © 2016 Royal Australasian College of Surgeons.

Anti-Epidermal Growth Factor Receptor Therapy in Head and Neck Squamous Cell Carcinoma: Focus on Potential Molecular Mechanisms of Drug Resistance

PubMed Central

2013-01-01

Targeted therapy against the epidermal growth factor receptor (EGFR) is one of the most promising molecular therapeutics for head and neck squamous cell carcinoma (HNSCC). EGFR is overexpressed in a wide range of malignancies, including HNSCC, and initiates important signal transduction pathways in HNSCC carcinogenesis. However, primary and acquired resistance are serious problems and are responsible for low single-agent response rate and tumor recurrence. Therefore, an improved understanding of the molecular mechanisms of resistance to EGFR inhibitors may provide valuable indications to identify biomarkers that can be used clinically to predict response to EGFR blockade and to establish new treatment options to overcome resistance. To date, no predictive biomarker for HNSCC is available in the clinic. Therapeutic resistance to anti-EGFR therapy may arise from mechanisms that can compensate for reduced EGFR signaling and/or mechanisms that can modulate EGFR-dependent signaling. In this review, we will summarize some of these molecular mechanisms and describe strategies to overcome that resistance. PMID:23821327

Evaluation of the Effects of Dental Implants on Oral Lesions.

2015-05-01

To determine whether dental implants impress oral lesions, and to evaluate the nature of their effect on the lesions. A comprehensive search was done via Google and PubMed for articles (including case reports and literature reviews) containing the keywords 'oral squamous cell carcinoma' (OSCC), 'oral lichen planus' (OLP), 'lichenoid contact reaction' (LCR), 'osseointegrated implants', and 'dental implants' , in the last 10 years (2002-2012). The study included 24 articles involving patients with dental implants, and some oral lesions (e.g. oral lichen planus and oral squamous cell carcinoma) or with a history of lesions. In these publications, there is evidence suggesting the possibility of emergence, exacerbation, recurrence, or even malignant transformation of the oral lesions after implant placement in some cases. Based on our review of the literature, implant treatment does not seem to be completely safe under any circumstances, but may have some complications in subjects with certain diseases (e.g. oral lesions, autoimmune diseases, malignancies, allergic reactions, etc.). Therefore prior to treatment, patients should be fully informed of the risks. Implant treatment is best done with caution in patients with cancer or mucocutaneous disorders.

To analyse the relationship of pre-operative body mass index with surgical complications and oncological outcomes in patients undergoing microvascular reconstruction for head and neck squamous cell cancer. A retrospective review was conducted of 259 patients who underwent microvascular free flap reconstruction after head and neck ablative surgery. Mean body mass index was 22.48 kg/m2. There were no correlations between body mass index and: flap failure (p = 0.739), flap ischaemia (p = 0.644), pharyngocutaneous fistula (p = 0.141) or wound infection (p = 0.224). The five-year disease-specific survival rate was 63 per cent. On univariate analysis, the five-year disease-specific survival rate was significantly correlated with pre-operative body mass index, based on Kaplan-Meier survival curves (p = 0.028). The five-year disease-specific survival rates in underweight, normal weight, overweight and obese groups were 47 per cent, 55 per cent, 65 per cent and 80 per cent, respectively. Pre-operative body mass index was a useful predictor for recurrence and survival in patients who underwent microvascular reconstruction for head and neck squamous cell cancer.

Prognostic factors in oral cavity and oropharyngeal squamous cell carcinoma (SCC) are debated. The purpose of this study was to investigate the association of prognostic factors with oncologic outcomes. Patients with oral cavity and oropharyngeal SCC treated from 1997 to 2012 were included in this retrospective cohort study. Associations of prognostic factors with locoregional recurrence (LRR) or overall survival (OS) were analyzed using the logistic regression and the Cox models. Six hundred thirty-four patients were included in this study; tumor size, surgical margins, and N classification were associated with LRR (p < .0001); considering histopathology: perineural invasion, lymphocytic infiltration, infiltrative borders, and N classification were significant determinants of LRR. Tumor size, N classification, alcoholism, and surgical margins were associated with OS (p < .0001); considering pathologic prognostic factors, perivascular invasion, islands borders, and surgical margins were independently associated with OS (p < .0001). Surgical margins, perineural and perivascular invasion, lymphocytic infiltration, and infiltrative patterns of tumor invasion are significant prognostic factors in oral cavity and oropharyngeal SCC. © 2015 Wiley Periodicals, Inc.

To analyze our surgical management and the result of squamous cell carcinoma (SCC) of vulva. Retrospectively, we collected 38 cases of SCC; 17 cases of them were early SCC and 21 cases were locally advanced. The patients underwent primary surgery. The survival was estimated using Kaplan-Meier analysis and the log rank test. The mean age was 60.78 years. Total vulvectomy was performed in all patients. Superficial and deep incision of bilateral inguinal lymphadenectomy was performed by separates incisions for SCC infiltrating more than 1mm. The average tumor size was 53 mm (10 to 140mm). Morbidity was 42.1%. Lateral resection margin ≥8mm was obtained in 57.1%. Eighteen patients benefited from adjuvant radiotherapy. The follow-up median was 19.4 months (6 to 61.5 month) with 05 recurrences in 12 months. The survival using the Kaplan-Meyer analysis at 5 years, was 62.1% (71.2%N(-) vs 46.7%N(+); p = 0.13). We identified two groups for locally advanced vulva cancer. Primary surgery keeps its place. Neo adjuvant radio chemotherapy followed by surgery is the alternative treatment for locally extensive lesions.

Increasing evidence suggests that miR-194 is down-regulated in esophageal squamous cell carcinoma tumor tissue. However, the role and underlying mechanism of miR-194 in esophageal squamous cell carcinoma have not been well defined. We used DIANA, TargetScan and miRanda to perform target prediction analysis and found KDM5B is a potential target of miR-194. Based on these findings, we speculated that miR-194 might play a role in esophageal squamous cell carcinoma development and progression by regulation the expression of KDM5B. We detected the expression of miR-194 and KDM5B by quantitative real-time reverse transcription PCR (qRT-PCR) and Western blot assays, respectively, and found down-regulation of miR-194 and up-regulation of KDM5B existed in esophageal squamous cell carcinoma cell lines. By detecting proliferation, invasion and apoptosis of TE6 and TE14 cells transfected with miR-194 mimics or mimic control, miR-194 was found to inhibit proliferation and invasion and promote apoptosis of esophageal squamous cell carcinoma cells. miR-194 was further verified to regulate proliferation, apoptosis and invasion of esophageal squamous cell carcinoma cells by directly targeting KDM5B. Furthermore, animal studies were performed and showed that overexpression of miR-194 inhibited the growth of esophageal squamous cell carcinoma tumors in vivo. These results confirmed our speculation that miR-194 targets KDM5B to inhibit esophageal squamous cell carcinoma development and progression. These findings offer new clues for esophageal squamous cell carcinoma development and progression and novel potential therapeutic targets for esophageal squamous cell carcinoma. © 2016 by the Society for Experimental Biology and Medicine.

C-reactive protein levels: a prognostic marker for patients with head and neck cancer?

2010-01-01

Background Recent advances in understanding complex tumor interactions have led to the discovery of an association between inflammation and cancer, in particular for colon and lung cancer, but only a very few have dealt with oral cancer. Therefore, the aim of the current study was to investigate the significance of preoperative C-reactive protein (CRP) levels as a parameter for development of lymph node metastases or recurrence. Materials and methods In 278 patients with oral cancer, preoperative CRP levels were compared with development of recurrence and metastasis. Results In 27 patients from the normal CRP group, and in 21 patients from the elevated CRP group, local recurrence was observed. Concerning lymph node metastases, 37 patients were in the normal group and 9 patients in the elevated CRP group. No significant correlation could be found between elevated CRP levels and metastasis (p = 0.468) or recurrence (p = 0.137). Conclusion Our findings do not appear to support a correlation between preoperative CRP levels and development of recurrence or metastases. In further studies, CRP levels in precancerous lesions and in Human Papilloma Virus (HPV) positive patients with oral squamous cell carcinoma (SCC) should be studied. PMID:20673375

Patients with secondary/ recurrent squamous cell head and neck cancer (SCCHN) have poor prognoses. Outcomes of re-irradiation with ≥42 Gy plus paclitaxel for secondary/recurrent SCCHN are herein presented. Two patients re-irradiated for secondary/recurrent SCCHN were evaluated. Patients received 44.4 Gy (2×1.2 Gy/day) or 42.0 Gy (2×1.5 Gy/day), respectively, plus concurrent paclitaxel (35 mg/m 2 weekly or 20 mg/m 2 twice per week). One patient developed a locoregional recurrence and additional metastases at 12 months after re-irradiation and died at 13 months. The other patient developed multiple bone metastases at 103 months and died at 104 months. Acute toxicities included grade 2 anemia and mucositis in both patients. Radiation dermatitis was grade 2 in one patient and grade 3 in the other. Re-irradiation with 42.0-44.4 Gy given twice daily plus paclitaxel was well tolerated and achieved a favorable response. The results need to be confirmed in a prospective trial. Copyright© 2018, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.

This study was undertaken to evaluate the significance of further qualification of atypical squamous cells of undetermined significance in routine Papanicolaou smears. A retrospective medical records review was conducted on 316 women whose Papanicolaou smears yielded diagnoses of either atypical squamous cells of undetermined significance suggestive of the presence of an intraepithelial lesion or atypical squamous cells of undetermined significance suggestive of a reactive process. The overall incidence of a squamous intraepithelial lesion (cervical intraepithelial neoplasia grades I, II, and III) was higher in the group with atypical squamous cells of undetermined significance suggestive of the presence of an intraepithelial lesion than in the group with results suggestive of a reactive process (41.1% vs 22.3%; P =.0344). Women with atypical squamous cells of undetermined significance suggestive of the presence of an intraepithelial lesion were 9.7 times more likely to have high-grade squamous intraepithelial lesion (cervical intraepithelial neoplasia III) develop than were women with atypical squamous cells of undetermined significance suggestive of a reactive process (95% confidence interval, 1.26-74.64). The incidence of high-grade squamous intraepithelial lesion was higher among women 35 years old (17.8% vs 6.3%; P =.0378). Women with a diagnosis of atypical squamous cells of undetermined significance suggestive of the presence of an intraepithelial lesion are more likely to have intraepithelial lesions develop than are those with atypical squamous cells of undetermined significance suggestive of a reactive process. Aggressive evaluation of cases of atypical squamous cells of undetermined significance suggestive of the presence of an intraepithelial lesion with colposcopy and cervical biopsies may be appropriate. Age should be considered as an independent factor in the plan of management.

To assess the impact of histology on recurrence patterns and survival outcomes in patients with esophageal cancer (EC) treated with definitive chemoradiotherapy (CRT). We analyzed 590 consecutive EC patients who received definitive CRT from 1998 to 2014, including 182 patients (30.8%) with squamous cell carcinoma (SCC) and 408 (69.2%) with adenocarcinoma. Recurrence pattern and timing, survival, and potential prognostic factors were compared. After a median follow-up time of 58.0months, the SCC group demonstrated a comparable locoregional recurrence rate (42.9% vs. 38.0%, P=0.264) but a significantly lower distant failure rate (27.5% vs. 48.0%, P<0.001) than adenocarcinoma group. No significant difference was found in overall survival or locoregional failure-free survival between groups, whereas the SCC group was associated with significantly more favorable recurrence-free survival (P=0.009) and distant metastasis-free survival (P<0.001). The adenocarcinoma group had higher hematogenous metastasis rates of bone, brain, and liver, whereas the SCC group had a marginally higher regional recurrence rate. Among patients who received salvage surgery after locoregional recurrence, no significant difference in survival was found between groups (P=0.12). The patterns and sites of recurrence, survival outcomes, and prognostic factors were significantly different between esophageal SCC and adenocarcinoma. Copyright © 2017 Elsevier B.V.

Most primarily cultured laryngeal squamous cell carcinoma cells are difficult to propagate in vitro and have a low survival rate. However, in our previous work to establish a laryngeal squamous cell carcinoma cell line, we found that laryngeal cancer-associated fibroblasts appeared to strongly inhibit the apoptosis of primarily cultured laryngeal squamous cell carcinoma cells in vitro. In this study, we investigated whether paired laryngeal cancer-associated fibroblasts alone can effectively support the growth of primarily cultured laryngeal squamous cell carcinoma cells in vitro. In all, 29 laryngeal squamous cell carcinoma specimens were collected and primarily cultured. The laryngeal squamous cell carcinoma cells were separated from cancer-associated fibroblasts by differential trypsinization and continuously subcultured. Morphological changes of the cultured laryngeal squamous cell carcinoma cells were observed. Immunocytofluorescence was used to authenticate the identity of the cancer-associated fibroblasts and laryngeal squamous cell carcinoma cells. Flow cytometry was used to quantify the proportion of apoptotic cells. Western blot was used to detect the protein levels of caspase-3. Enzyme-linked immunosorbent assay was used to detect the levels of chemokine (C-X-C motif) ligand 12, chemokine (C-X-C motif) ligand 7, hepatocyte growth factor, and fibroblast growth factor 1 in the supernatants of the laryngeal squamous cell carcinoma and control cells. AMD3100 (a chemokine (C-X-C motif) receptor 4 antagonist) and an anti-chemokine (C-X-C motif) ligand 7 antibody were used to block the tumor-supporting capacity of cancer-associated fibroblasts. Significant apoptotic changes were detected in the morphology of laryngeal squamous cell carcinoma cells detached from cancer-associated fibroblasts. The percentage of apoptotic laryngeal squamous cell carcinoma cells and the protein levels of caspase-3 increased gradually in subsequent subcultures. In contrast, no significant differences in the proliferation capacity of laryngeal squamous cell carcinoma cells cocultured with cancer-associated fibroblasts were detected during subculturing. High level of chemokine (C-X-C motif) ligand 12 was detected in the culture supernatant of cancer-associated fibroblasts. The tumor-supporting effect of cancer-associated fibroblasts was significantly inhibited by AMD3100. Our findings demonstrate that the paired laryngeal cancer-associated fibroblasts alone are sufficient to support the primary growth of laryngeal squamous cell carcinoma cells in vitro and that the chemokine (C-X-C motif) ligand 12/chemokine (C-X-C motif) receptor 4 axis is one of the major contributors.

Purpose Tumors with oncogenic dependencies on the HER family of receptor tyrosine kinases (RTKs) often respond well to targeted inhibition. Our previous work suggested that many cell lines derived from squamous cell carcinomas of the head and neck (SCCHNs) depend on autocrine signaling driven by HER2/3 dimerization and high-level co-expression of HRG. Additionally, results from a Phase I trial of MEHD7495A, a dual-action antibody that blocks ligand binding to EGFR and HER3, suggest that high-level HRG expression was associated with clinical response in SCCHN patients. Here we explore the hypothesis that high-level HRG expression defines a subpopulation of SCCHNs with activated HER3. Experimental Design qRT-PCR expression profiling was performed on >750 tumors of diverse origin, including >150 therapy-naïve, primary, and recurrent SCCHNs. Activated HER3, defined by immunoprecipitation of phospho-HER3, was compared to HRG expression in SCCHN samples. Paracrine versus autocrine expression was evaluated using RNA-in situ hybridization. Results SCCHN tumors express the highest levels of HRG compared to a diverse collection of other tumor types. We show that high HRG expression is associated with activated HER3, whereas low HRG expression is associated with low HER3 activation in SCCHN tumors. Furthermore, HRG expression is higher in recurrent SCCHN compared to patient-matched therapy naïve specimens. Conclusions HRG expression levels define a biologically distinct subset of SCCHN patients. We propose that high-level expression of HRG is associated with constitutive activation of HER3 in SCCHN and thus defines an actionable biomarker for interventions targeting HER3. PMID:23468880

Lichen sclerosus is an inflammatory skin disorder affecting anogenital areas in males and females that is associated with squamous cell carcinoma. However, there is a lack of data on the role of biomarkers for predicting lichen sclerosus progression to squamous cell carcinoma. We focused on early protein markers of squamous cell carcinoma and their expression in lichen sclerosus to improve the mechanistic and diagnostic understanding of lichen sclerosus. We performed an extensive PubMed® and MEDLINE® search for protein markers found in early stages of vulvar and penile squamous cell carcinoma, and their prevalence in associated lichen sclerosus lesions. In recent years several markers have been implicated as precursor markers for malignant transformation of lichen sclerosus into squamous cell carcinoma, including p53, Ki-67, γ-H2AX, MCM3 and cyclin D1. These proteins are up-regulated in lichen sclerosus of the vulva/penis and squamous cell carcinoma. Various levels of evidence show an association between lichen sclerosus and squamous cell carcinoma. p16 is over expressed in penile and vulvar squamous cell carcinoma associated with human papillomavirus infection but conflicting reports exist about its expression in lichen sclerosus. The angiogenesis markers vascular endothelial growth factor and cyclooxygenase-2 are expressed at higher levels, and microvessel density is increased in vulvar lichen sclerosus and squamous cell carcinoma, indicating a possible similar association in penile lichen sclerosus. Only a minority of lichen sclerosus cases are associated with squamous cell carcinoma. However, the therapeutic implications of a squamous cell carcinoma diagnosis are severe. Clinically, we lack an understanding of how to separate indolent lichen sclerosus cases from those in danger of progression to squamous cell carcinoma. Several protein markers show promise for further delineating the pathobiology of lichen sclerosus and the potential malignant transformation into squamous cell carcinoma.

MicroRNA-448 (miR-448) has been showed to be low-expressed and function as tumor suppressor in most human cancers. However, there are limited reports on the clinical significance and biological function of miR-448 in lung squamous cell carcinoma. In this study, we observed that miR-448 expression was decreased in lung squamous cell carcinoma tissues and cell lines. Meanwhile, miR-448 expression associated with differentiated degree, T classification (tumor size), N classification (lymph node metastasis), M classification (distant metastasis), clinical stage and prognosis of lung squamous cell carcinoma patients. In survival analysis, low expression of miR-448 was a poor independent prognostic factor for lung squamous cell carcinoma patients. Moreover, gain-of-function and loss-of-function studies showed miR-448 acted as a tumor suppressor regulating lung squamous cell carcinoma cells growth and metastasis. Furthermore, DCLK1 has been identified as a potential target for miR-448 to regulate lung squamous cell carcinoma cells growth and metastasis. In conclusion, miR-448 low-expression was a poor prognostic factor for lung squamous cell carcinoma patients, and miR-448 served as a tumor suppressor in lung squamous cell carcinoma cells via targeting DCLK1.

In squamous cell carcinoma, squamous cell carcinoma antigen levels are often elevated. This multi-center study evaluated the technical performance of a new Elecsys ® squamous cell carcinoma assay, which measures serum squamous cell carcinoma antigen 1 and 2 levels in an equimolar manner, and investigated the potential of squamous cell carcinoma antigen for differential diagnosis of cervical, lung, and head and neck squamous cell carcinoma.Assay precision and method comparison experiments were performed across three European sites. Reference ranges for reportedly healthy individuals were determined using samples from banked European and Chinese populations. Differential diagnosis experiments determined whether cervical, lung, or head and neck cancer could be differentiated from apparently healthy, benign, or other malignant cohorts using squamous cell carcinoma antigen levels alone. Squamous cell carcinoma antigen cut-off levels were calculated based on squamous cell carcinoma antigen levels at 95% specificity. Repeatability coefficients of variation across nine analyte concentrations were ≤5.3%, and intermediate precision coefficients of variation were ≤10.3%. Method comparisons showed good correlations with Architect and Kryptor systems (slopes of 1.1 and 1.5, respectively). Reference ranges for 95th percentiles for apparently healthy individuals were 2.3 ng/mL (95% confidence interval: 1.9-3.8; European cohort, n = 153) and 2.7 ng/mL (95% confidence interval: 2.2-3.3; Chinese cohort, n = 146). Strongest differential diagnosis results were observed for cervical squamous cell carcinoma: receiver operating characteristic analysis showed that squamous cell carcinoma antigen levels (2.9 ng/mL cut-off) differentiate cervical squamous cell carcinoma (n = 127) from apparently healthy females (n = 286; area under the curve: 86.2%; 95% confidence interval: 81.8-90.6; sensitivity: 61.4%; specificity: 95.6%), benign diseases (n = 187; area under the curve: 86.3%; 95% confidence interval: 81.2-91.3; sensitivity: 61.4%; specificity: 95.0%), and other cervical cancers (n = 157; area under the curve: 78.9%; 95% confidence interval: 70.8-87.1; sensitivity: 61.4%; specificity: 86.7%). Squamous cell carcinoma may also aid in the differential diagnosis of lung cancer. The Elecsys squamous cell carcinoma assay exhibited good technical performance and is suitable for differential diagnosis of cervical squamous cell carcinoma in clinical practice.

To describe patterns of recurrence of elective nodal irradiation (ENI) in definitive chemoradiotherapy (CRT) for thoracic esophageal squamous cell carcinoma (SqCC) using 3D-conformal radiotherapy. One hundred and twenty-six consecutive patients with stages I-IVB thoracic esophageal SqCC newly diagnosed between June 2000 and July 2009 and treated with 3D-CRT in our institution were recruited from our database. Definitive CRT consisted of two cycles of nedaplatin/5FU repeated every 4 weeks, with concurrent radiation therapy of 50-50.4 Gy in 25-28 fractions. Until completion, radiotherapy was delivered to the N1 and M1a lymph nodes as ENI in addition to gross tumor volume. All 126 patients were included in this analysis, and their tumors were staged as follows: T1/T2/T3/T4, 28/18/54/26; N0/N1, 50/76; M0/M1a/M1b, 91/5/30. The mean follow-up period for the 63 surviving patients was 28.3 (±22.8) months. Eighty-seven patients (69%) achieved complete response (CR) without any residual tumor at least once after completion of CRT. After achieving CR, each of 40 patients experienced failures (local=20 and distant=20) and no patient experienced elective nodal failure without having any other site of recurrence. The upper thoracic esophageal carcinoma showed significantly more (34%) relapses at the local site than the middle (9%) or lower thoracic (11%) carcinomas. The 2-year and 3-year overall survival was 56% and 43%, respectively. The 1-year, 2-year and 3-year disease-free survival was 46%, 38% and 33%, respectively. In CRT for esophageal SqCC, ENI was effective for preventing regional nodal failure. The upper thoracic esophageal carcinomas had significantly more local recurrences than the middle or lower thoracic sites. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Verrucous carcinoma (VC) is an exophytic, low-grade, well-differentiated variant of squamous cell carcinoma. It is described as a lesion appearing in the sixth or seventh decade of life that has minimal aggressive potential and, in long-standing cases, has been shown to transform into squamous cell carcinoma. Oral submucous fibrosis (OSMF) is a potentially malignant disorder, and about one-third of the affected population develop oral squamous cell carcinoma. The histopathological diagnosis of verrucous carcinoma is challenging, and the interpretation of early squamous cell carcinoma requires immense experience. Here we present a rare case of a 24-year-old male with OSMF transforming to verrucous carcinoma with invasive squamous cell carcinoma. Even though the case had a straightforward clinical diagnosis, the serial sectioning done for pathological diagnosis disclosed the squamous cell carcinoma.

Purpose Patients with squamous non-small-cell lung cancer (NSCLC) have poor prognosis and limited treatment options. This randomized, double-blind, phase III study investigated the efficacy and safety of first-line ipilimumab or placebo plus paclitaxel and carboplatin in advanced squamous NSCLC. Patients and Methods Patients with stage IV or recurrent chemotherapy-naïve squamous NSCLC were randomly assigned (1:1) to receive paclitaxel and carboplatin plus blinded ipilimumab 10 mg/kg or placebo every 3 weeks on a phased induction schedule comprising six chemotherapy cycles, with ipilimumab or placebo from cycles 3 to 6 and then, after induction treatment, ipilimumab or placebo maintenance every 12 weeks for patients with stable disease or better. The primary end point was overall survival (OS) in patients receiving at least one dose of blinded study therapy. Results Of 956 randomly assigned patients, 749 received at least one dose of blinded study therapy (chemotherapy plus ipilimumab, n = 388; chemotherapy plus placebo, n = 361). Median OS was 13.4 months for chemotherapy plus ipilimumab and 12.4 months for chemotherapy plus placebo (hazard ratio, 0.91; 95% CI, 0.77 to 1.07; P = .25). Median progression-free survival was 5.6 months for both groups (hazard ratio, 0.87; 95% CI, 0.75 to 1.01). Rates of grade 3 or 4 treatment-related adverse events (TRAEs), any-grade serious TRAEs, and TRAEs leading to discontinuation were numerically higher with chemotherapy plus ipilimumab (51%, 33%, and 28%, respectively) than with chemotherapy plus placebo (35%, 10%, and 7%, respectively). Seven treatment-related deaths occurred with chemotherapy plus ipilimumab, and one occurred with chemotherapy plus placebo. Conclusion The addition of ipilimumab to first-line chemotherapy did not prolong OS compared with chemotherapy alone in patients with advanced squamous NSCLC. The safety profile of chemotherapy plus ipilimumab was consistent with that observed in previous lung and melanoma studies. Ongoing studies are evaluating ipilimumab in combination with nivolumab in this population.

The majority of patients with a squamous cell carcinoma of the head and neck present with locally advanced tumors. The first-line treatment of locally advanced tumor stages consists of a combined modality management. Despite these aggressive protocols, many patients develop locoregional recurrences or metastasis and place particularly high demands on the interdisciplinary treatment team. Treatment with a curative intent must be differentiated from a palliative one. In addition to prior treatment, resectability, age and performance status, patient wishes must be taken into consideration in treatment planning, especially considering that most therapies offer little to no overall survival benefit. Salvage surgery, chemo- and target therapies, and reirradiation are head and neck surgeon's and radiooncologist's weapons in the fight against these strong opponents. This review focuses on publications and meeting news from last year and reviews the current status of the clinical application of each treatment modality in recurrent or metastatic head and neck cancer.

This in vitro study compares continuous wave and pulsed laser light at longer wavelengths for activation of the phototoxic drug hypericin in human cancer cells. Two-photon pulsed laser light now allows high-resolution fluorescent imaging of cancer cells and should provide deeper tissue penetration with near infrared light for improved detection as well as phototoxicity in human tumors. Cultured Seoul National University (SNU)-1 tumor cells from a squamous cell carcinoma (SCC) were incubated with hypericin before photoirradiation at four laser wavelengths. Phototoxicity of hypericin sensitized SCC cells was measured by dimethyl thiazoldiphenyl (MTT) tetrazolium bromide cell viability assays and by confocal fluorescence microscopy via 532-nm and infrared two-photon pulsed laser light. Phototoxic response increased linearly with hypericin dose of 0.1-2 microM, light exposure time of 5-120 sec, and pulsed dye laser wavelengths of 514-593 nm. Light energy delivery for 50% cell phototoxicity (LD50) response was 9 joules at 514 nm, 3 joules at 550 nm, and less than 1 joule at the 593 nm hypericin light absorption maxima. Fluorescence confocal microscopy revealed membrane and perinuclear localization of hypericin in the SNU cells with membrane damage seen after excitation with visible 532 nm continuous wave light or two-photon 700-950 nm picosecond pulsed laser irradiation. Hypericin may be a powerful tumor targetting drug when combined with pulsed laser light in patients with recurrent head and neck SCC.

To assess the effects of treatments for non-metastatic invasive squamous cell carcinoma (SCC) of the skin using evidence from observational studies, given the paucity of evidence from randomised controlled trials. Systematic review of observational studies. Medline, Embase, to December 2012. Observational studies of interventions for primary, non-metastatic, invasive, SCC of the skin that reported recurrence during follow-up, quality of life, initial response to treatment, adverse events, cosmetic appearance, or death from disease. Studies were excluded if data for primary cutaneous SCC was not separable from other data. Data were extracted independently by two reviewers. Meta-analysis was performed where appropriate using a random effects model to estimate the pooled proportion of an event with 95% confidence intervals. 118 publications were included, covering seven treatment modalities. Pooled estimates of recurrence of SCCs were lowest after cryotherapy (0.8% (95% confidence interval 0.1% to 2%)) and curettage and electrodesiccation (1.7% (0.5% to 3.4%)), but most treated SCCs were small, low risk lesions. After Mohs micrographic surgery, the pooled estimate of local recurrence during variable follow-up periods from 10 studies was 3.0% (2.2% to 3.9%), which was non-significantly lower than the pooled average local recurrence of 5.4% (2.5% to 9.1%) after standard surgical excision (12 studies), and 6.4% (3.0% to 11.0%) after external radiotherapy (7 studies). After an apparently successful initial response of SCCs to photodynamic therapy, pooled average recurrence of 26.4% (12.3% to 43.7%; 8 studies) was significantly higher than other treatments. Evidence was limited for laser treatment (1 study) and for topical and systemic treatments (mostly single case reports or small non-comparative series with limited follow-up). Many observational studies have looked at different treatment modalities for SCC, but the evidence base for the effectiveness of these interventions is poor. Comparison of outcomes after different treatments should be interpreted cautiously owing to biases inherent in the types of study included, and lack of direct comparisons to enable the estimation of relative treatment effect. Further evidence is needed to develop a prognostic model and stratify individuals at high risk of developing SCC, to improve the evidence base for this common cancer and to optimise clinical management.

Human papillomavirus-mediated carcinogenesis and HPV-associated oral and oropharyngeal squamous cell carcinoma. Part 2: Human papillomavirus associated oral and oropharyngeal squamous cell carcinoma

PubMed Central

2010-01-01

Human papillomavirus (HPV) infection of the mouth and oropharynx can be acquired by a variety of sexual and social forms of transmission. HPV-16 genotype is present in many oral and oropharyngeal squamous cell carcinomata. It has an essential aetiologic role in the development of oropharyngeal squamous cell carcinoma in a subset of subjects who are typically younger, are more engaged with high-risk sexual behaviour, have higher HPV-16 serum antibody titer, use less tobacco and have better survival rates than in subjects with HPV-cytonegative oropharyngeal squamous cell carcinoma. In this subset of subjects the HPV-cytopositive carcinomatous cells have a distinct molecular profile. In contrast to HPV-cytopositive oropharyngeal squamous cell carcinoma, the causal association between HPV-16 and other high-risk HPV genotypes and squamous cell carcinoma of the oral mucosa is weak, and the nature of the association is unclear. It is likely that routine administration of HPV vaccination against high-risk HPV genotypes before the start of sexual activity will bring about a reduction in the incidence of HPV-mediated oral and oropharyngeal squamous cell carcinoma. This article focuses on aspects of HPV infection of the mouth and the oropharynx with emphasis on the link between HPV and squamous cell carcinoma, and on the limitations of the available diagnostic tests in identifying a cause-and-effect relationship of HPV with squamous cell carcinoma of the mouth and oropharynx.

Background Acantholytic squamous cell carcinoma (aSCC) is regarded as a high-risk variant of cutaneous squamous cell carcinoma (SCC). Acantholytic actinic keratosis (aAK) has been regarded as a precursor risk factor for aSCC. However, supporting evidence is limited. Objective We sought to document clinical features, histologic features, management, and outcomes in a series of aSCC cases. Methods Definitions of aSCC, aAK, and aSCC arising in association with aAK were applied to a consecutive series of aSCC cases. Clinical characteristics and outcomes were obtained from electronic medical records. Results Of 115 aSCC cases (103 patients, mean age 71.8 years), actinic keratosis was present in 23% (27/115) but only 7.8% (9/115) exhibited associated aAK. Ten cases (10/115, 9%) fulfilled strict histologic criteria for follicular SCC as previously defined, but 50 of 115 (43%) of our aSCC cases exhibited predominant involvement of follicular epithelium rather than epidermis. Clinical outcome (median follow-up, 36 months) was available in 106 of 115 (92%). One patient experienced regional extension (parotid), and 1 patient experienced a local recurrence (nose). No disease-related metastases or deaths were documented. Limitations This was a single-institution retrospective study from the United States. Conclusions The presence of acantholysis in cutaneous SCC does not specifically confer aggressive behavior, a finding that may inform clinical practice guidelines. PMID:27889291

Objective Patients with head and neck squamous cell carcinoma (HNSCC) have significant wound-healing difficulties. While adipose-derived stem cells (ASCs) facilitate wound healing, ASCs may accelerate recurrence when applied to a cancer field. This study evaluates the impact of ASCs on HNSCC cell lines in vitro and in vivo. Study Design In vitro experiments using HNSCC cell lines and in vivo mouse experiments. Setting Basic science laboratory. Subjects and Methods Impact of ASCs on in vitro proliferation, survival, and migration was assessed using 8 HNSCC cell lines. One cell line was used in a mouse orthotopic xenograft model to evaluate in vivo tumor growth in the presence and absence of ASCs. Results Addition of ASCs did not increase the number of HNSCC cells. In clonogenic assays to assess cell survival, addition of ASCs increased colony formation only in SCC9 cells (maximal effect 2.3-fold, P < .02) but not in other HNSCC cell lines. In scratch assays to assess migration, fluorescently tagged ASCs did not migrate appreciably and did not increase the rate of wound closure in HNSCC cell lines. Addition of ASCs to HNSCC xenografts did not increase tumor growth. Conclusion Using multiple in vitro and in vivo approaches, ASCs did not significantly stimulate HNSCC cell proliferation or migration and increased survival in only a single cell line. These findings preliminarily suggest that the use of ASCs may be safe in the setting of HNSCC but that further investigation on the therapeutic use of ASCs in the setting of HNSCC is needed.

Charles River-CD Sprague-Dawley rats in 3 equal groups of 100 males and 100 females each were exposed to 12, 1, and 0 ppm of phenylglycidyl ether vapor for 24 months. Nasal tumors were first detected after 621 days' exposure at 12 ppm with an incidence of 11% in males and 4.4% in females. No nasal tumors were found at 1 ppm in rats exposed for 24 months. The nasal tumors, mostly epidermoid carcinomas, were derived from the respiratory epithelium and nasal glands, both of which revealed squamous metaplasia or dysplasia in the anterior nasal cavity. Most nasal tumors were confined to the anterior nasal cavity and occasionally invaded the dorsonasal bones and posterior nasal cavity. The undifferentiated glandular cells appear to differentiate to neoplastic squamous cells, because the ultrastructure of epidermoid carcinoma revealed traits of glandular cell differentiation in the neoplastic squamous cells. The features of glandular cell differentiation in the neoplastic squamous cells were intercellular or intracellular glandular lumens, secretory vesicles, mucus droplets, and intermediate cells showing both glandular and squamous differentiation. Squamous cells in the well-differentiated epidermoid carcinomas revealed abundant tonofibrils, desmosomes, glycogen particulates, and interdigitated cytoplasmic processes. These markers of squamous-cell differentiation were markedly reduced in the undifferentiated epidermoid carcinomas. The spindle-cell squamous carcinoma showed both squamous and fibroblastic-like differentiations. Some spindle cells had only fibroblastic-like differentiation, suggesting spindle-cell metaplasia of the squamous cells.

Local recurrences of the tumor at the surgical margin are serious problems in pulmonary resections for lung cancer. The aim of this study is to determine the involved margins and safe distances of the resection sites from tumor for prevention of local recurrences. In this prospective study, 66 patients operated for non-small cell lung carcinoma (NSCLC) from Jan 2006 to Sep 2008 were evaluated. After performing pulmonary resections, multiple biopsies were taken up from 5 mm (A), 10 mm (B), 15 mm (C), and 20 mm (D) distance from tumor. The specimens were studied histopathologically. From a total of66 patients with NSCLC admitted to our referral hospital, 25 (38%) had adenocarcinoma, 18 (27.3%) squamous cell carcinoma, 5 (7.5%) large cell carcinoma, 4 (6%) bronchoalveolar cell carcinoma, 4 (6%) adenoid cystic carcinoma, 3 (4.6%) malignant carcinoid tumor and 7 (10.6%) had metastasis. The most common symptoms were dyspnea and cough. Histopathologically tumor positive margins were found in 84.8% (A), 10.6% (B), 4.5% (C), and 0% (D). There was a significant statistically difference between tumor involvement at distances 5 mm (A) versus 10-20 mm (B-D) (P <0.001). A 20 mm distance from the gross tumor is considered as a safe surgical margin in any type of malignant pulmonary resections for prevention of local surgical recurrences if there was no pathologic examination before surgery.

KEYNOTE-012 was a phase Ib, multicohort study designed to investigate efficacy and safety of pembrolizumab in advanced solid tumors. Results from the subset of patients with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) from the Asia-Pacific region are reported. Patients with recurrent/metastatic HNSCC, measurable disease (RECIST version 1.1), and ECOG performance status (PS) 0-1 were eligible for enrollment in the HNSCC expansion cohort. Patients received pembrolizumab 200 mg every 3 weeks. Response was assessed every 8 weeks. Co-primary end-points were safety and overall response rate (RECIST version 1.1, central review). Secondary end-points included overall survival and response duration. Patients enrolled at any of the five centers throughout the Asia-Pacific region were included in these analyses. Twenty-six patients with HNSCC from the Asia-Pacific region received pembrolizumab. The median age was 62 years, 65% of patients had ECOG PS 1, and 62% had received two or more prior therapies for recurrent/metastatic disease. Sixteen (62%) patients experienced a treatment-related adverse event of any grade, including two (8%) patients who experienced one or more events of grade 3 severity. No treatment-related deaths occurred. The overall response rate was 19% (95% confidence interval, 7%-39%). After a median follow-up of 12 months (range, 2-21 months), a median response duration was not reached (range, 6 to 17+ months); four of five responses lasted ≥6 months. Median overall survival was 11.6 months (95% confidence interval, 4.7-17.7 months). Pembrolizumab was well tolerated and had durable antitumor activity in patients with HNSCC from the Asia-Pacific region. (Trial registration no. NCT01848834.). © 2017 The Authors.

We report 2-year results from CheckMate 141 to establish the long-term efficacy and safety profile of nivolumab and outcomes by tumor PD-L1 expression in patients with recurrent or metastatic (R/M),platinum-refractory squamous cell carcinoma of the head and neck (SCCHN). Patients with R/M SCCHN with tumor progression/recurrence within 6 months of platinum therapy were randomized 2:1 to nivolumab 3 mg/kg every 2 weeks or investigator's choice (IC). Primary endpoint: overall survival (OS). Data cutoff: September 2017. With 24.2 months' minimum follow-up, nivolumab (n = 240) continued to improve OS vs IC (n = 121), hazard ratio (HR) = 0.68 (95% CI 0.54-0.86). Nivolumab nearly tripled the estimated 24-month OS rate (16.9%) vs IC (6.0%), and demonstrated OS benefit across patients with tumor PD-L1 expression ≥1% (HR [95% CI] = 0.55 [0.39-0.78]) and  < 1% (HR [95% CI] = 0.73 [0.49-1.09]), and regardless of tumor HPV status. Estimated OS rates at 18, 24, and 30 months with nivolumab were consistent irrespective of PD-L1 expression (<1%/≥1%). In the nivolumab arm, there were no observed differences in baseline characteristics or safety profile between long-term survivors and the overall population. Grade 3-4 treatment-related adverse event rates were 15.3% and 36.9% for nivolumab and IC, respectively. Nivolumab significantly improved OS at the primary analysis and demonstrated prolonged OS benefit vs IC and maintenance of a manageable and consistent safety profile with 2-year follow-up. OS benefit was observed with nivolumab irrespective of PD-L1 expression and HPV status. (Clinicaltrials.gov: NCT02105636). Copyright © 2018. Published by Elsevier Ltd.

To evaluate outcomes for patients with pathological N3 (pN3) neck disease from human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) and determine variables predictive of survival. Retrospective case series with chart review. This study was conducted between 1998 and 2013 and included patients with HPV-related OPSCC treated with surgery with or without adjuvant therapy and who had pN3 nodal disease. The primary outcome was disease-specific survival (DSS). Secondary outcomes included overall survival (OS), disease-free survival (DFS), adverse events, and gastrostomy tube rates. Thirty-nine patients were included, of whom 36 (90%) underwent adjuvant therapy. Median follow-up was 39 months (range, 2-147 months). Mean age was 56 years, and 87% were male. Seventeen patients (44%) underwent selective neck dissection, whereas six (15%) underwent radical (n = 2) or extended radical (n = 4) neck dissection. Ninety-two percent had extracapsular extension. Five-year Kaplan-Meier estimated DSS, OS, and DFS were 89% (95% confidence interval [CI]: 79%-99%), 87% (95% CI: 75%-99%), and 84% (95% CI: 72%-96%), respectively. The disease recurrence rate was 10% (5% regional, 5% distant metastasis). Patients with less than 5 pathologically positive lymph nodes (P = .041) had improved DFS. Patients with HPV-related OPSCC and pN3 nodal disease treated with surgery and adjuvant therapy have very favorable long-term survival and regional control. Patients with five or more pathologically positive lymph nodes may be at higher risk for recurrence. 4.

Background We conducted a phase II clinical trial of induction chemotherapy followed by surgery ± radiotherapy for squamous cell carcinoma of the oral tongue (SCCOT) in young adults. Methods From September 2001 to October 2004, 23 patients aged 18–49 years with clinical T2-3N0-2M0 SCCOT and no prior radiotherapy, chemotherapy, or neck dissection underwent induction chemotherapy (paclitaxel, ifosfamide, and carboplatin) followed by glossectomy and neck dissection ± radiotherapy and chemotherapy. Results On final surgical pathology, 9 (39%) patients had a complete/major (2 complete) histologic response at the primary tumor site; 8 (35%) had no response or progression. Similarly, 9 (39%) patients had a complete response in the neck or remained node negative; 6 (26%) had an increase in nodal category. No treatment-associated deaths occurred, and toxicity was modest. At a median follow-up from the end of treatment of 52 months (minimum, 23 months), 10 (43%) patients developed recurrence, and all 10 died of cancer. Crude recurrence/cancer death rates were associated with ≤ a partial response at the tongue (P = .029), poor histologic differentiation (P = .012), and multiple adverse features on final surgical pathology (P = .040). Conclusions Response rates and overall survival with this induction chemotherapy regimen were limited, but complete/major response at the tongue was associated with excellent prognosis. Additionally, improved patient selection and predictive tumor biomarkers will be needed for induction chemotherapy to be routinely incorporated into the treatment of oral tongue cancer in young adults.

A previous randomized trial in recurrent Head and Neck squamous-cell carcinoma (HNSCC) has shown re-irradiation combined with chemotherapy after salvage surgery significantly improved disease-free survival (DFS). The objective of this randomized trial was to compare two methods of re-irradiation in terms of toxicity and survival. Patients with recurrence/second primary in previously irradiated area were randomly allocated to receive either 60 Gy over 11 weeks with concomitant 5FU - hydroxyurea (VP-arm), or 60 Gy (1.2 Gy twice daily) over 5 weeks with cetuximab (HFR-arm). Primary endpoint was treatment interruption >15 days (acute toxicity). Twenty-six patients were included in VP-arm and 27 in HFR-arm. One patient in VP-arm experienced >15 days interruption due to toxicity, and none in HFR-arm. In both arms, all patients received at least 60 Gy. In VP-arm, 8/26 patients had chemotherapy delay and/or dose reduction. In HFR-arm, 4/27 patients had <6 cycles cetuximab. There was no significant difference in overall survival (Median OS: 37.4 months vs 21.9 months, p = 0.12). Toxicities and DFS were not different between 2 arms. Twice daily schedule of re-irradiation of 60 Gy/5 weeks with cetuximab was tolerable and no significant difference in treatment delays occurred between two arms. Copyright © 2018 Elsevier B.V.

Purpose: Intensification of radiotherapy and chemotherapy for head-and-neck cancer may lead to increased rates of dysphagia. Dosimetric predictors of objective findings of long-term dysphagia were sought. Methods and Materials: From an institutional database, 83 patients were identified who underwent definitive intensity-modulated radiotherapy for squamous cell carcinoma of the head and neck, after exclusion of those who were treated for a second or recurrent head-and-neck primary lesion, had locoregional recurrence at any time, had less than 12 months of follow-up, or had postoperative radiotherapy. Dosimetric parameters were analyzed relative to three objective endpoints as a surrogate for severe long-term dysphagia: percutaneousmore » endoscopic gastrostomy (PEG) tube dependence at 12 months, aspiration on modified barium swallow, or pharyngoesophageal stricture requiring dilation. Results: Mean dose greater than 41 Gy and volume receiving 60 Gy (V{sub 60}) greater than 24% to the larynx were significantly associated with PEG tube dependence and aspiration. V{sub 60} greater than 12% to the inferior pharyngeal constrictor was also significantly associated with increased PEG tube dependence and aspiration. V{sub 65} greater than 33% to the superior pharyngeal constrictor or greater than 75% to the middle pharyngeal constrictor was associated with pharyngoesophageal stricture requiring dilation. Conclusions: Doses to the larynx and pharyngeal constrictors predicted long-term swallowing complications, even when controlled for other clinical factors. The addition of these structures to intensity-modulated radiotherapy optimization may reduce the incidence of dysphagia, although cautious clinical validation is necessary.« less

Histopathologic risk factors in oral and oropharyngeal squamous cell carcinoma variants: An update with special reference to HPV-related carcinomas

PubMed Central

2014-01-01

Accurate identification of the microscopic risk factors of oral and oropharyngeal (OP) squamous cell carcinomas (SCC) and their morphologic variants is of at most importance, as these generally determine treatment modalities, prognosis and overall patient outcome. The great majority of oral and oropharyngeal squamous cell carcinomas are microscopically described as kerartinizing squamous cell carcinoma (KSCC). They bear certain resemblance to keratinizing stratified squamous epithelium. Tobacco habits and excessive consumption of alcoholic beverages have been considered to be the main etiologic agents in these carcinomas. The tumors occurred in older patients more commonly affected the oral tongue and floor of the mouth with well established morphologic risk factors including tumor grade, pattern of invasion and perineural involvement. Within the last 30 years however, the advent and expanding prevalence of high risk human papillomavirus (HPV) as an important etiologic agent for head and neck squamous cell carcinoma, particularly in the OP, has resulted in a significant change in the established morphologic criteria for risk assessment. The majority of HPV relate carcinomas of the OP are nonkeratinizing squamous cell carcinoma (NKSCC). These tumors are found to be more responsive to treatment with a favorable patient outcome and good prognosis. Consequently, alterations in treatment protocols aimed at de-escalation are currently being evaluated. More recently, other morphologic variants that are HPV positive are reported with increasing frequency in the OP and other head and neck sites. As a result, several clinical and pathologic questions have emerged. Importantly, whether the virus is biologically active in these tumors and involved in their pathogenesis, and second, what are the clinical implications with regard to patient management and outcome in the HPV-related variants. Examples of HPV-related squamous cell carcinoma variants that will be addressed here are: basaloid squamous cell carcinoma (BSCC), undifferentiated carcinoma (UCa), papillary squamous carcinoma (PSCC) and small cell carcinoma. Some studies have suggested favorable prognosis in some variants, analogous to that of the (NKSCC), while others showed poorer outcome. So far the number of studies on this subject is limited and the number of cases evaluated in each investigation is few. Because of that, it is prudent at this stage, not to alter management protocols as a result of identification of HPV in these variants and to await additional information Key words:Histopathologic risk-factors, oral cavity, oropharynx, squamous cell carcinoma variants, keratinizing squamous cell carcinoma, nonkeratinizing squamous cell carcinoma, HPV, basaloid squamous cell carcinoma, undifferentiated carcinoma, papillary squamous cell carcinoma, small cell carcinoma.

Heart transplantation after lung cancer surgery can be questionable because of the high risk of cancer recurrence. We report the results of two patients. The first underwent right lobectomy in 2008 for pT1N0 adenocarcinoma, heart-transplantation in 2010, and surgery for synchronous adenocarcinoma and squamous-cell carcinoma in 2012. The second underwent left segmentectomy for pT1aN0 adenosquamous carcinoma and transplantation in 1995 and then surgery for pT1aN1 adenocarcinoma in 2013. Posttransplantation lung cancer histologic analysis results were different in both cases, demonstrating the absence of metastatic recurrence. Thus, early stage lung cancer might not be a contraindication to heart transplantation, nor are long delays be necessary before registering on a waiting list.

In recent years, abnormal RNA editing has been shown to play an important role in the development of esophageal squamous cell carcinoma, as such abnormal editing is catalyzed by ADAR (adenosine deaminases acting on RNA). However, the regulatory mechanism of ADAR1 in esophageal squamous cell carcinomas remains largely unknown. In this study, we investigated ADAR1 expression and its association with RNA editing in esophageal squamous cell carcinomas. RNA sequencing applied to esophageal squamous cell carcinoma clinical samples showed that ADAR1 expression was correlated with the expression of STAT1, STAT2, and IRF9. In vitro experiments showed that the abundance of ADAR1 protein was associated with the induced activation of the JAK/STAT pathway by type I interferon. RNA sequencing results showed that treatment with type I interferon caused an increase in the number and degree of RNA editing in esophageal squamous cell carcinoma cell lines. In conclusion, the activation of the JAK/STAT pathway is a regulatory mechanism of ADAR1 expression and causes abnormal RNA editing profile in esophageal squamous cell carcinoma. This mechanism may serve as a new target for esophageal squamous cell carcinoma therapy.

Squamous cell carcinoma variants of the upper aerodigestive tract: a comprehensive review with a focus on genetic alterations.

Squamous cell carcinoma of the upper aerodigestive tract is a heterogenous entity. Although conventional squamous cell carcinomas are easily recognized, the morphologic variants of squamous cell carcinoma can present a diagnostic challenge. Familiarity with these variants is necessary because many are associated with unique risk factors and are characterized by specific molecular alterations (eg, nuclear protein in testis midline carcinomas). Perhaps the most important distinction is in identifying viral-related from nonviral-related carcinomas. The accurate diagnosis of these variants is necessary for prognostic and therapeutic reasons. To provide a clinicopathologic overview and summary of the molecular alterations of the common squamous cell carcinoma variants, including verrucous, spindle cell, acantholytic, adenosquamous, basaloid, and papillary squamous cell carcinoma, as well as nuclear protein in testis midline carcinoma, and to discuss the distinguishing features of human papillomavirus- and Epstein-Barr virus-related squamous cell carcinomas. Published peer-reviewed literature. Familiarity with squamous cell carcinoma variants is essential for proper diagnosis and to guide appropriate clinical management. Further insight into the molecular alterations underlying those variants may lead to alterations in existing treatment approaches and to evolution of novel treatment modalities.

Metastatic tonsillar squamous cell carcinoma masquerading as a pancreatic cystic tumor and diagnosed by EUS-guided FNA.

2017-11-01

Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA). This represents a third reported case of metastatic squamous cell carcinoma to the pancreas from the head and neck region. Metastatic squamous cell carcinoma should be considered in the differential diagnosis of EUS-FNA during evaluation of pancreatic cystic lesion. © 2017 Wiley Periodicals, Inc.

The collagen gel droplet-embedded culture drug sensitivity test (CD-DST) is an anticancer drug sensitivity test that uses a method of three-dimensional culture of extremely small samples, and it is suited to primary cultures of human cancer cells. It is a useful method for oral squamous cell carcinoma (OSCC), in which the cancer tissues available for testing are limited. However, since the optimal contact concentrations of anticancer drugs have yet to be established in OSCC, CD-DST for detecting drug sensitivities of OSCC is currently performed by applying the optimal contact concentrations for stomach cancer. In the present study, squamous carcinoma cell lines from human oral cancer were used to investigate the optimal contact concentrations of cisplatin (CDDP) and fluorouracil (5-FU) during CD-DST for OSCC. CD-DST was performed in 7 squamous cell carcinoma cell lines derived from human oral cancers (Ca9-22, HSC-3, HSC-4, HO-1-N-1, KON, OSC-19 and SAS) using CDDP (0.15, 0.3, 1.25, 2.5, 5.0 and 10.0 µg/ml) and 5-FU (0.4, 0.9, 1.8, 3.8, 7.5, 15.0 and 30.0 µg/ml), and the optimal contact concentrations were calculated from the clinical response rate of OSCC to single-drug treatment and the in vitro efficacy rate curve. The optimal concentrations were 0.5 µg/ml for CDDP and 0.7 µg/ml for 5-FU. The antitumor efficacy of CDDP at this optimal contact concentration in CD-DST was compared to the antitumor efficacy in the nude mouse method. The T/C values, which were calculated as the ratio of the colony volume of the treatment group and the colony volume of the control group, at the optimal contact concentration of CDDP and of the nude mouse method were almost in agreement (P<0.05) and predicted clinical efficacy, indicating that the calculated optimal contact concentration is valid. Therefore, chemotherapy for OSCC based on anticancer drug sensitivity tests offers patients a greater freedom of choice and is likely to assume a greater importance in the selection of treatment from the perspectives of function preservation and quality of life, as well as representing a treatment option for unresectable, intractable or recurrent cases.

To study the clinicopathologic features, diagnosis and differential diagnosis of sinonasal teratocarcinosarcoma (SNTCS) and olfactory neuroblastoma (ONB), and to discuss the histogenesis and possible relationship between SNTCS and ONB. Seven cases of SNTCS and 34 cases of ONB were retrieved from the pathological archives together with one case each of malignant teratoma and immature embryonic tissue at 8 weeks were collected from Beijing Tongren Hospital. The clinicopathologic features were analyzed and immunohistochemical staining was performed on paraffin sections. Six of the SNTCS patients were male and one was female. The patients age range was 25 to 69 years (mean age 46). Four cases were initial presentation and three were recurrences. Histologically, the tumor shows multiple tissue components derived from three germ layers. There were mixture of teratoma-like tissue and carcinosarcoma. The components include fetal clear cell squamous epithelium derived from ectoderm. Glandular and tubular structures and ciliated columnar epithelium derived from endoderm. Fibroblasts, striated muscle, smooth muscle, cartilage and osteoid matrix derived from mesoderm. The carcinoma component exhibited mostly adenocarcinoma and squamous cell carcinoma, whereas the sarcoma component mostly exhibited rhabdomyosarcoma, leiomyosarcoma, and fibrosarcoma. In addition, carcinoid, and primitive mesenchymal tissue and the ONB component were also seen. The morphological characteristics of SNTCS comprised fetal clear cell squamous epithelium, carcinosarcoma and the ONB component. By immunohistochemistry, the epithelial component and cells with epithelium differentiation were positive for cytokeratin (pan) and EMA. The ONB component was positive for Syn, NSE, CD99, NF and CgA to different degrees. Neurofibril bundles were positive for S-100, and Flexner-Wintersteiner rosettes expressed cytokeratin (pan) and EMA. The spindle cells expressed vimentin, SMA, desmin, myosin and myoglobin. The primitive mesenchymal tissue expressed vimentin, and the mucoid materials and glycogen were positive for PAS. GFAP was negative in all cases. The 34 cases of ONB, included 18 men and 16 women, the age ranged from 12 to 72 years (mean 42.8 years). Microscopically, the tumor shows epithelial nests, net of angioma-like fibrous connective tissues, small round and spindle cells, glandular, squamous-like cells, and cells of rhabdomyoblastic differentiation, Homer-Wright and Flexner rosette, bundles of neurofibrils, etc. NSE and CgA were expressed in small cells. S-100 protein was positive in the areas of bunches of neurofibril. Cytokeratin (pan) was positive in epithelial cells. Myoglobin was positive in the cells of rhabdomyoblastic differentiation. The single case of immature malignant teratoma exhibited primitive nerve tissue, but fetal clear cell squamous epithelium was not found. In the immature embryonic tissue, rudimentary organs were formed, with fetal clear cell squamous epithelium lining present on the nasal and oral cavities surface. SNTCS is a rare and aggressive malignant neoplasm. Most of ONB are low-grade malignant tumors. Morphological differences are the most important basis to make differentiate SNTCS from ONB. As SNTCS may demonstrate a multiplicity of structures and pleomorphism, inadequate sampling at biopsy, therefore, may lead to errors in diagnosis. No evidence show that SNTCS are derived from germ cells and sinonasal teratoid carcinosarcoma may be a more proper name. SNTCS probably arises from primitive totipotential cells of olfactory/sinonasal membrane, and the relationship between SNTCS and ONB needs further study.

Cutaneous squamous cell carcinomas arise as secondary cancers in hematopoietic stem cell transplant survivors. They have been documented primarily in Western cohorts and relatively little is known about their occurrence in Asian hematopoietic stem cell transplant recipients, with no reports of squamous cell carcinomas with high-risk features in Asian patients. We describe a case of a cutaneous squamous cell carcinoma with high-risk features on the scalp of a Japanese bone marrow transplant recipient approximately 6.5 years post-transplant, who was on long-term voriconazole. The history of a photodistributed erythema followed by the appearance of multiple actinic keratoses and solar lentigines, together with the rarity of cutaneous squamous cell carcinomas in Asian hematopoietic stem cell transplant cohorts revealed in our literature review, suggest that voriconazole use contributed to the development of high-risk squamous cell carcinoma in our patient. © 2017 Japanese Dermatological Association.

To investigate hypoxia-induced factor-1 alpha expression in distinct oral squamous cell carcinoma subtypes and topographies and correlate with clinicopathological data. Hypoxia-induced factor-1 alpha expression was assessed by immunohistochemistry in 93 cases of OSCC. Clinical and histopathological data were reviewed from medical records. Hypoxia-induced factor-1 alpha status was distinct according to tumor location, subtype and topography affect. In superficial oral squamous cell carcinomas, most tumor cells overexpressed hypoxia-induced factor-1 alpha, whereas hypoxia-induced factor-1 alpha was restricted to the intratumoral region in conventional squamous cell carcinomas. All basaloid squamous cell carcinomas exhibited downregulation of hypoxia-induced factor-1 alpha. Interestingly, metastatic lymph nodes (91.7%, p = 0.001) and the intratumoral regions of corresponding primary tumors (58.3%, p = 0.142) showed hypoxia-induced factor-1 alpha-positive tumor cells. Overall survival was poor in patients with metastatic lymph nodes. Hypoxia-induced factor-1 alpha has distinct expression patterns in different oral squamous cell carcinoma subtypes and topographies, suggesting that low oxygen tension promotes the growth pattern of superficial and conventional squamous cell carcinoma, but not basaloid squamous cell carcinoma. Indeed, a hypoxic environment may facilitate regional metastasis, making it a useful diagnostic and prognostic marker in primary tumors.

It is still unclear that dissection of recurrent laryngeal nerve nodes is mandatory in patients with cT1 middle or lower thoracic esophageal squamous cell carcinoma when the nodes are negative in preoperative staging workup. We aimed to evaluate the feasibility of near-infrared image-guided lymphatic mapping of bilateral recurrent laryngeal nerve nodes. The day before operation, we injected indocyanine green (ICG) into the submucosal layer by endoscopy. At the time of upper mediastinal dissection, ICG-stained basins were identified along the bilateral recurrent laryngeal nerves and retrieved under guidance of the Firefly system. After the operation, remnant ICG-unstained basins were dissected from the specimen to assess the presence of metastasis. Of 29 patients enrolled, ICG-stained basins could be identified in 25 patients (86.2%), and 6 of them (24.0%) had nodal metastasis; 4 in the right recurrent laryngeal nerve chain, 1 in the left recurrent laryngeal nerve chain, and 1 in both recurrent laryngeal nerve chains. On pathologic examination of 345 recurrent laryngeal nerve nodes, two metastatic nodes were identified in ICG-unstained basins along the left recurrent laryngeal nerve in a patient who had lymph node metastases in ICG-stained basins along both recurrent laryngeal nerves. Negative predictive value in detection of nodal metastasis was 100% for the right recurrent laryngeal nerve chain and 98.2% for the left recurrent laryngeal nerve chain. Real-time assessment of recurrent laryngeal nerve nodes with near-infrared image was technically feasible, and we could detect lymphatic basins that most likely have nodal metastasis. Our technique might be useful in determining the optimal extent of lymphadenectomy. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

We aimed to evaluate the feasibility and reliability of brush cytology in the biomarker expression profiling of oral squamous cell carcinomas within the concept of theranostics, and to correlate this biomarker profile with patient measurable outcomes. Markers representative of prognostic gene expression changes in oral squamous cell carcinoma was selected. These markers were also selected to involve pathways for which commercially available or investigational agents exist for clinical application. A set of 7 markers were analysed by immunocytochemistry on the archival primary tumour material of 99 oral squamous cell carcinoma patients. We confirmed the feasibility of the technique for the expression profiling of oral squamous cell carcinomas. Furthermore, our results affirm the prognostic significance of the epidermal growth factor receptor (EGFR) family and the angiogenic pathway in oral squamous cell carcinoma, confirming their interest for targeted therapy. Brush cytology appears feasible and applicable for the expression profiling of oral squamous cell carcinoma within the concept of theranostics, according to sample availability.

Radioresistance often leads to poor survival in concurrent chemoradiotherapy-treated cervical squamous cell carcinoma, and reliable biomarkers can improve prognosis. We compared the prognostic potential of hemoglobin, absolute neutrophil count, and absolute lymphocyte count with that of squamous cell carcinoma antigen in concurrent chemoradiotherapy-treated squamous cell carcinoma. We analyzed 152 patients with concurrent chemoradiotherapy and high-dose-rate intracavitary brachytherapy-treated cervical squamous cell carcinoma. Hemoglobin, absolute neutrophil count, absolute lymphocyte count, and squamous cell carcinoma antigen were quantitated and correlated with survival, using Cox regression, receiver operating characteristic curve analysis, and Kaplan-Meier plots. Both hemoglobin and absolute lymphocyte count in the second week of concurrent chemoradiotherapy (Hb2 and ALC2) and squamous cell carcinoma antigen in the third week of concurrent chemoradiotherapy (mid-squamous cell carcinoma antigen) correlated significantly with disease-specific survival and progression-free survival. The ratio of high-dose-rate intracavitary brachytherapy dose to total dose (high-dose-rate intracavitary brachytherapy ratio) correlated significantly with progression-free survival. Patients with both low Hb2 (≤11 g/dL) and ALC2 (≤639 cells/µL) showed a lower 5-year disease-specific survival rate than those with high Hb2 and/or ALC2, regardless of mid-squamous cell carcinoma antigen (mid-squamous cell carcinoma antigen: ≤4.7 ng/mL; 5-year disease-specific survival rate: 85.5% vs 94.6%, p = 0.0096, and mid-squamous cell carcinoma antigen: >4.7 ng/mL; 5-year disease-specific survival rate: 43.8% vs 66.7%, p = 0.192). When both Hb2 and ALC2 were low, the low high-dose-rate intracavitary brachytherapy ratio (≤0.43) subgroup displayed significantly lower 5-year disease-specific survival rate compared to the subgroup high high-dose-rate intracavitary brachytherapy ratio (>0.43) (62.5% vs 88.2%, p = 0.0067). Patients with both anemia and lymphopenia during concurrent chemoradiotherapy showed poor survival, independent of mid-squamous cell carcinoma antigen, and escalating high-dose-rate intracavitary brachytherapy ratio might improve survival.

OBJECTIVE: To compare the repetitive DNA patterns of human actinic keratoses and squamous cell carcinomas to determine the genetic alterations that are associated with malignant transformation. INTRODUCTION: Cancer cells are prone to genomic instability, which is often due to DNA polymerase slippage during the replication of repetitive DNA and to mutations in the DNA repair genes. The progression of benign actinic keratoses to malignant squamous cell carcinomas has been proposed by several authors. MATERIAL AND METHODS: Eight actinic keratoses and 24 squamous cell carcinomas (SCC), which were pair-matched to adjacent skin tissues and/or leucocytes, were studied. The presence of microsatellite instability (MSI) and the loss of heterozygosity (LOH) in chromosomes 6 and 9 were investigated using nine PCR primer pairs. Random Amplified Polymorphic DNA patterns were also evaluated using eight primers. RESULTS: MSI was detected in two (D6S251, D9S50) of the eight actinic keratosis patients. Among the 8 patients who had squamous cell carcinoma-I and provided informative results, a single patient exhibited two LOH (D6S251, D9S287) and two instances of MSI (D9S180, D9S280). Two LOH and one example of MSI (D6S251) were detected in three out of the 10 patients with squamous cell carcinoma-II. Among the four patients with squamous cell carcinoma-III, one patient displayed three MSIs (D6S251, D6S252, and D9S180) and another patient exhibited an MSI (D9S280). The altered random amplified polymorphic DNA ranged from 70% actinic keratoses, 76% squamous cell carcinoma-I, and 90% squamous cell carcinoma-II, to 100% squamous cell carcinoma-III. DISCUSSION: The increased levels of alterations in the microsatellites, particularly in D6S251, and the random amplified polymorphic DNA fingerprints were statistically significant in squamous cell carcinomas, compared with actinic keratoses. CONCLUSION: The overall alterations that were observed in the repetitive DNA of actinic keratoses and squamous cell carcinomas indicate the presence of a spectrum of malignant progression.

Fonseca, L M; do Carmo, M A

Ten inflammatory fibrous hyperplasias, ten papillomas, and nineteen oral squamous cell carcinomas were analyzed by the AgNOR technique to determine if different disturbances of oral epithelia presented different AgNOR counts. The papilloma group showed higher mean AgNOR counts (3.15 +/- 0.58) than the hyperplasia group (1.98 +/- 0.24) and smaller than the well-differentiated oral squamous cell carcinoma group (6.56 +/- 1.25) and poorly differentiated oral squamous cell carcinoma group (7.07 +/- 1.60). The differences among the groups of lesions were statistically significant (P < 0.05) except between the well differentiated oral squamous cell carcinoma group and the poorly differentiated oral squamous cell carcinoma group. Our findings suggest that the cellular proliferation ratio in papillomas is greater than hyperplasias and smaller than carcinomas.

In this systematic review, we evaluated studies involving adjuvant and primary topical treatment for ocular surface squamous neoplasia (OSSN). The findings were: (i) adjuvant 5-fluorouracil (5-FU) reduces the risk of relapse after surgical excision with mild side effects [level Ib, grade of recommendation (GR) A]. (ii) Primary topical mitomycin (MMC) produces a high rate of complete response, low recurrence rate, and mild side effects (level Ib, GR A). (iii) Primary chemotherapy versus adjuvant chemotherapy produce similar rates of recurrence, with no significant difference (level IIb, GR B). (iv) Adjuvant 5-FU versus MMC showed no significant differences, with mild side effects in both groups and a better toxicity profile for MMC (level III, GR C). (v) Primary topical 5-FU versus MMC versus interferon (IFN) showed similar rates of tumor recurrence, mild side effects for all drugs, and more severe side effects in the 5-FU arm, followed successively by MMC and IFN (level III, GR C).

Basaloid squamous cell carcinoma (SCC) of the anus, previously called cloacogenic carcinoma, is a subtype of SCC. There are very few data on the morphologic variation within basaloid SCC of the anus, which may contribute to misdiagnosis. We retrospectively evaluated cases originally diagnosed as basaloid SCC for histologic characterization. We retrieved and reviewed cases of basaloid SCC from 1994 to 2013. Ten (27%) cases were reclassified after review, including basal cell carcinoma (n=6), melanoma (n=2), and neuroendocrine carcinoma (n=2). The final group of basaloid SCC (n=27) showed a female predominance (median age=60 y; range, 42 to 92 y). Morphologically, basaloid SCC could be categorized into 4 groups: transitional carcinoma like (n=10), basaloid with peripheral palisade (n=13), adenoid cystic carcinoma like (n=3), and mucinous microcystic (n=1). In 19 cases the histologic patterns were pure and were mixed in the remainder. CK5/6, p16, and high-risk HPV were positive in all cases (n=27). SOX2 was positive in 18/22 cases. Clinical follow-up was available on 60% of cases; 9 patients (53%) developed local recurrence or metastasis, and 5 (29%) died of disease. Basaloid SCC of the anus is characterized by 4 major histologic patterns and is consistently HPV driven.

Despite expressing high levels of the epidermal growth factor receptor (EGFR), a majority of oral squamous cell carcinoma (OSCC) patients show limited response to cetuximab and ultimately develop drug resistance. However, mechanism underlying cetuximab resistance in OSCC is not clearly understood. Here, using a mouse orthotopic xenograft model of OSCC, we show that bone morphogenic protein-7-phosphorylated Smad-1, -5, -8 (BMP7-p-Smad1/5/8) signaling contributes to cetuximab resistance. Tumor cells isolated from the recurrent cetuximab-resistant xenograft models exhibited low EGFR expression but extremely high levels of p-Smad1/5/8. Treatment with the bone morphogenic protein receptor type 1 (BMPRI) inhibitor, DMH1 significantly reduced cetuximab-resistant OSCC tumor growth, and combined treatment of DMH1 and cetuximab remarkably reduced relapsed tumor growth in vivo. Importantly, p-Smad1/5/8 level was elevated in cetuximab-resistant patients and this correlated with poor prognosis. Collectively, our results indicate that the BMP7-p-Smad1/5/8 signaling is a key pathway to acquired cetuximab resistance, and demonstrate that combination therapy of cetuximab and a BMP signaling inhibitor as potentially a new therapeutic strategy for overcoming acquired resistance to cetuximab in OSCC.

Biomarkers that facilitate the prediction of disease recurrence in head and neck squamous cell carcinoma (HNSCC) may enable physicians to personalize treatment. In the current study, DNA promoter methylation of programmed cell death 1 (PDCD1, PD-1) was evaluated as a prognostic biomarker in HNSCC patients. High PDCD1 methylation (mPDCD1) was associated with a significantly shorter overall survival after surgical resection in both the discovery (HR = 2.24 [95%CI: 1.08-4.64], p = 0.029) and the validation cohort (HR = 1.54 [95%CI: 1.08-2.21], p = 0.017). In multivariate Cox proportional hazards analysis, PDCD1 methylation remained a significant prognostic factor for HNSCC (HR = 2.14 [95%CI: 1.19-3.84], p = 0.011). Further, mPDCD1 was strongly associated with the human papilloma virus (HPV) status. mPDCD1 was assessed retrospectively in a discovery cohort of 120 HNSCC patients treated at the University Hospital of Bonn and a validation cohort of 527 HNSCC cases analyzed by The Cancer Genome Atlas Research Network. PDCD1 methylation might aid the identification of HNSCC patients potentially benefitting from a radical or alternative treatment, particularly in the context of immunotherapies targeting PD-1/PD-L1.

The multifunctional involvement and infiltration of myeloid cells (tumor-associated tissue eosinophils [TATE] and mast cells) can provide a unique opportunity to define relevant effectors functions that may represent novel, therapeutic options for modulation of tumor onset/growth. Our study aimed to evaluate infiltration of myeloid cells (TATE and Mast cells) infiltration in different grades (WHO grading) of oral squamous cell carcinoma (OSCC). Total 30 cases of OSCC were selected for this study. Hematoxylin and eosin stain and toluidine blue special stain, to evaluate TATE and the mast cells infiltration, were used. Three-year follow-up of OSCC cases was done. Among 30 cases, 63.33% cases of OSCC showed TATE-positive and 36.66% cases showed TATE-negative. Regarding mast cells infiltration, 66.66% OSCC cases showed mast cells positive and 33.33% cases did not show significant mast cells infiltration. We found significant association of TATE and mast cells infiltration in OSCC cases. These myeloid cells infiltration significantly associated with age of patients but did not show any significant association with gender, site, and habit of cases. When we compared these cells infiltration with clinical stages and different histological grades of tumor, we found their infiltration is decreasing, from Stages 1 to Stage 3 of tumor and from well to poorly differentiated carcinoma. We have also found the less infiltration of these myeloid in recurrence cases of OSCC. As the infiltration of TATE and mast cells are correlated, along with evaluation of TATE, we should also evaluate the presence of mast cells infiltration in OSCC. The assessment of myeloid cells could become, in the future, useful for therapeutic approaches in this subset of the patient.

Keratoacanthomas rarely occur in the conjunctiva. We report a case of a 24-year-old man with a rapidly growing conjunctival mass. The tumor was excised with a safety margin to exclude squamous cell carcinoma and was histopathologically diagnosed as a keratoacanthoma. There has been no recurrence over 2 years of follow-up. To the best of our knowledge, he is the youngest patient to be diagnosed with conjunctival keratoacanthoma who had no known risk factors such as skin disorders, trauma, surgery, or infection. In similar cases, we recommend complete early surgical excision and careful follow-up to exclude malignancy.

Purpose: To evaluate outcome and describe clinical treatment guidelines for patients with primary squamous cell carcinoma of the vagina treated with definitive radiation therapy. Methods and Materials: Between 1970 and 2000, a total of 193 patients were treated with definitive radiation therapy for squamous cell carcinoma of the vagina at The University of Texas M. D. Anderson Cancer Center. The patients' medical records were reviewed to obtain information about patient, tumor, and treatment characteristics, as well as outcome and patterns of recurrence. Surviving patients were followed for a median of 137 months. Survival rates were calculated using the Kaplan-Meier method,more » with differences assessed using log-rank tests. Results: Disease-specific survival (DSS) and pelvic disease control rates correlated with International Federation of Gynecology and Obstetrics (FIGO) stage and tumor size. At 5 years, DSS rates were 85% for the 50 patients with Stage I, 78% for the 97 patients with Stage II, and 58% for the 46 patients with Stage III-IVA disease (p = 0.0013). Five-year DSS rates were 82% and 60% for patients with tumors {<=}4 cm or >4 cm, respectively (p = 0.0001). At 5 years, pelvic disease control rates were 86% for Stage I, 84% for Stage II, and 71% for Stage III-IVA (p = 0.027). The predominant mode of relapse after definitive radiation therapy was local-regional (68% and 83%, respectively, for patients with stages I-II or III-IVA disease). The incidence of major complications was correlated with FIGO stage; at 5 years, the rates of major complications were 4% for Stage I, 9% for Stage II, and 21% for Stage III-IVA (p < 0.01). Conclusions: Excellent outcomes can be achieved with definitive radiation therapy for invasive squamous cell carcinoma of the vagina. However, to achieve these results, treatment must be individualized according to the site and size of the tumor at presentation and the response to initial external-beam radiation therapy. Brachytherapy plays an important role in the treatment of many vaginal cancers but should be carefully selected and applied to obtain optimal coverage of the target volume.« less

HPV-negative penile squamous cell carcinoma: disruptive mutations in the TP53 gene are common.

The majority of penile squamous cell carcinomas is caused by transforming human papilloma virus (HPV) infection. The etiology of HPV-negative cancers is unclear, but TP53 mutations have been implicated. Archival tissues of 108 invasive squamous cell carcinoma from a single pathology institution in a low-incidence area were analyzed for HPV-DNA and p16 ink4a overexpression and for TP53 mutations by ion torrent next-generation sequencing. Library preparation failed in 32/108 squamous cell carcinomas. Institutional review board approval was obtained. Thirty of 76 squamous cell carcinomas (43%; average 63 years) were HPV-negative with 8/33 squamous cell carcinomas being TP53 wild-type (24%; average 63 years). Twenty-five of 33 squamous cell carcinomas (76%; average 65 years) showed 32 different somatic TP53 mutations (23 missense mutations in exons 5-8, 6 nonsense, 1 frameshift and 2 splice-site mutations). Several hotspot mutations were detected multiple times (R175H, R248, R282, and R273). Eighteen of 19 squamous cell carcinomas with TP53 expression in immunohistochemistry had TP53 mutations. Fifty percent of TP53-negative squamous cell carcinomas showed mostly truncating loss-of-function TP53 mutations. Patients without mutations had longer survival (5 years: 86% vs 61%; 10 years: 60% vs 22%), but valid clinically relevant conclusions cannot be drawn due to different tumor stages and heterogeneous treatment of the cases presented in this study. Somatic TP53 mutations are a common feature in HPV-negative penile squamous cell carcinomas and offer an explanation for HPV-independent penile carcinogenesis. About half of HPV-negative penile cancers are driven by oncogenic activation of TP53, while a quarter is induced by loss of TP53 tumor suppressor function. Detection of TP53 mutations should be carried out by sequencing, as immunohistochemical TP53 staining could not identify all squamous cell carcinomas with TP53 mutations.

Locoregional Recurrent or Second Primary Head and Neck Cancer: Management Strategies and Challenges.

2016-01-01

Treatment of patients with locoregional recurrent or second primary head and neck squamous cell cancer (HNSCC) has been guided by well-reasoned principles and informed by carefully tested chemotherapy and radiation regimens. However, clinical decision making for this population is complicated by many factors. Although surgery is generally considered the treatment of choice for patients with HNSCC with recurrent disease or new second primary disease in a previously irradiated field, operability of cases is not always straightforward. Postoperative treatment is frequently warranted but carries significant risk. In addition, the rapid rise in the incidence of HPV-associated HNSCC raises the question of whether established treatment paradigms should be re-examined in this population of patients with a much better prognosis than the non-HPV population. Furthermore, new radiation techniques and new systemic agents show early promising results in recent clinical studies, suggesting potential for practice-changing effects in the future management of this disease. This article examines each of the treatment modalities used in the care of patients with HNSCC with recurrent or new second primary disease and provides a perspective to aid clinicians in the management of this disease.

Leptin, one of the main hormones controlling energy homeostasis, has been associated with different cancer types. In oral cancer, its effect is not well understood. We investigated, through in vitro and in vivo assays, whether leptin can affect the neoplastic behavior of oral squamous cell carcinoma. Expression of genes possibly linked to the leptin pathway was assessed in leptin-treated oral squamous cell carcinoma cells and also in tissue samples of oral squamous cell carcinoma and oral mucosa, including leptin, leptin receptor, hypoxia-inducible factor 1-alpha, E-cadherin, matrix metalloproteinase-2, matrix metalloproteinase-9, Col1A1, Ki67, and mir-210. Leptin treatment favored higher rates of cell proliferation and migration, and reduced apoptosis. Accordingly, leptin-treated oral squamous cell carcinoma cells show decreased messenger RNA caspase-3 expression, and increased levels of E-cadherin, Col1A1, matrix metalloproteinase-2, matrix metalloproteinase-9, and mir-210. In tissue samples, hypoxia-inducible factor 1-alpha messenger RNA and protein expression of leptin and leptin receptor were high in oral squamous cell carcinoma cases. Serum leptin levels were increased in first clinical stages of the disease. In animal model, oral squamous cell carcinoma-induced mice show higher leptin receptor expression, and serum leptin level was increased in dysplasia group. Our findings suggest that leptin seems to exert an effect on oral squamous cell carcinoma cells behavior and also on molecular markers related to cell proliferation, migration, and tumor angiogenesis.

Queensland, Australia, has the highest rates of cutaneous squamous cell carcinoma (SCC). Perineural invasion (PNI) is associated with reduced local control and survival. A retrospective review of a prospective database of patients with clinical PNI from cutaneous SCC of the head and neck (SCCHN) treated with surgery and postoperative radiotherapy (PORT) between 2000 and 2011 and a minimum of 24 months follow-up. Patients were excluded if immunosuppressed, had non-SCC histology, or were treated palliatively. Fifty patients (mean age, 60 years) with median follow-up of 50 months were included in this study. A total of 54.8% of known primary tumors had incidental PNI. Ten percent had nodal disease at presentation. MRI neurogram was positive in 95.8%. Recurrence-free survival (RFS) at 5-years was 62%. Five-year disease-specific survival (DSS) and overall survival (OS) were 75% and 64%, respectively. There were no perioperative deaths. This report demonstrates that long-term survival is achievable in patients with clinical PNI from cutaneous SCCHN after surgery and PORT. © 2015 Wiley Periodicals, Inc.

AIM To evaluate PIK3CA gene mutational status in Northwest Chinese esophageal squamous cell carcinoma (ESCC) patients, and examine the associations of PIK3CA gene mutations with clinicopathological characteristics and clinical outcome. METHODS A total of 210 patients with ESCC who underwent curative resection were enrolled in this study. Pyrosequencing was applied to investigate mutations in exons 9 and 20 of PIK3CA gene in 210 Northwest Chinese ESCCs. The associations of PIK3CA gene mutations with clinicopathological characteristics and clinical outcome were examined. RESULTS PIK3CA gene mutations in exon 9 were detected in 48 cases (22.9%) of a non-biased database of 210 curatively resected Northwest Chinese ESCCs. PIK3CA gene mutations were not associated with sex, tobacco use, alcohol use, tumor location, stage, or local recurrence. When compared with wild-type PIK3CA gene cases, patients with PIK3CA gene mutations in exons 9 experienced significantly better disease-free survival and overall survival rates. CONCLUSION The results of this study suggest that PIK3CA gene mutations could act as a prognostic biomarker in Northwest Chinese ESCC patients. PMID:28465643

Clinical and histological data of 168 patients with squamous cell carcinoma of the vulva were analyzed with respect to survival. 151 patients underwent surgery, 12 patients were treated with primary radiation and in 5 patients no treatment was performed. Follow-up lasted from at least 2 up to 22 years' posttreatment. In univariate analysis, the following factors were highly significant: presurgery lymph node status, tumor infiltration beyond the vulva, tumor grading, histological inguinal lymph node status, pre- and postsurgery tumor stage, depth of invasion and tumor diameter. In the multivariate analysis (Cox regression), the most powerful factors were shown to be histological inguinal lymph node status, tumor diameter and tumor grading. The multivariate logistic regression analysis worked out as main prognostic factors for metastases of inguinal lymph nodes: presurgery inguinal lymph node status, tumor size, depth of invasion and tumor grading. Based on these results, tumor biology seems to be the decisive factor concerning recurrence and survival. Therefore, we suggest a more conservative treatment of vulvar carcinoma. Patients with confined carcinoma to the vulva, with a tumor diameter up to 3 cm and without clinical suspected lymph nodes, should be treated by wide excision/partial vulvectomy with ipsilateral lymphadenectomy.

The prognostic impact of the size and number of nodal metastases in head and neck cutaneous squamous cell carcinoma (SCC) is well established. The purpose of this study was to validate the prognostic significance of the lymph node ratio in metastatic head and neck cutaneous SCC. A retrospective review of 326 patients with head and neck cutaneous SCC with parotid and/or cervical nodal metastases was performed. The primary endpoints were overall survival (OS) and disease-free survival (DFS). The minimal-P approach was used to investigate the optimal lymph node ratio threshold. Our data included 77 recurrences and 101 deaths. A lymph node ratio of 6% was a significant predictor of shorter DFS (hazard ratio [HR] 1.62; 95% confidence interval [CI] 1.11-2.38; P = .01) and OS (HR 1.63; 95% CI 1.03-2.58; P = 0.04) on multivariable analysis. The lymph node ratio is an independent prognosticator of survival outcomes in patients presenting with metastatic head and neck cutaneous SCC. A lymph node ratio >6% is a significant threshold to categorize patients into low and high risk. © 2018 Wiley Periodicals, Inc.

Tuberculosis (TB) is still a major public health problem in the world, with many factors contributing to this burden, including poor living conditions, overcrowding, poverty, malnutrition, illiteracy, and rapid spread of human immunodeficiency virus infection. Cutaneous tuberculosis is a less common form of extrapulmonary tuberculosis, and in this paucibacillary form the diagnosis depends on histopathology, tuberculin positivity, and response to treatment. The diagnosis is even more difficult in cases with drug resistant Mycobacterium tuberculosis due to lack of awareness and lack of facilities to diagnose drug resistant tuberculosis. In this article, we describe an unusual case of multidrug resistant lupus vulgaris (LV), in a 34-year-old male who responded to anti-tubercular treatment (ATT) initially, but developed recurrent disease which failed to respond to standard four-drug ATT; subsequently, tissue culture showed growth of multidrug resistant M. tuberculosis. Subsequently, he also developed cutaneous squamous cell carcinoma. This article aims to exemplify a grave complication that can occur in long-standing case of LV, the limitations faced by clinicians in developing countries where tuberculosis is endemic, and classical methods of proving drug resistance are generally unavailable or fail.

Squamous cell carcinoma (SCC) is the most common type of malignancy affecting the oral cavity. While exposures to main risk factors for oral SCC such as smoking and alcohol use are higher amongst the Aboriginal people, little is known about oral cancer in this population. This study aimed to describe characteristics and survival of oral SCC in Aboriginal and non-Aboriginal Western Australians. All primary oral SCC cases reported to the Western Australian Cancer Registry (WACR) between 1990 and 1999 were analysed with respect to person characteristics including: date of birth, sex and indigenous status; and disease characteristics including: date of biopsy, disease stage and site as well as date of recurrence and date of death. Exclusion criteria included diagnosis not based on incisional or excisional biopsy, diagnosis other than oral SCC or a history of another malignant neoplasm. Aboriginal individuals were more likely to reside in rural areas. No statistically significant differences in oral SCC characteristics and survival were noted between Aboriginal and non-Aboriginal Western Australians. This study provides new information on person and disease characteristics of Aboriginal Western Australians diagnosed with oral SCC.

Statement of the Problem: Sinonasal papilloma (SNP) is a rare benign lesion characterized by high recurrence rate and malignant transformation. Purpose: This study aimed to investigate the prevalence of human papilloma virus (HPV) infection in these lesions in South of Iran. Materials and Method: In this cross sectional retrospective study, a total of 41 patients, 38 SNP and 3 SNP/Squamous cell carcinoma cases, from 2007 to 2014 were studied. Human papilloma virus (HPV) DNA detection was performed by nested PCR method and positive cases were analyzed for high risk HPV-16 and HPV-18. Results: HPV was detected in 31.7%; HPV- 16 in 4.9% and HPV 18 was not detected at all. Dysplastic epithelium was detected in 53% that was not associated with HPV. Three cases were accompanied with malignant transformation that HPV genome was detected in only one case and none of them were positive for HPV16 /18 genomic DNA. Conclusion: Current research suggests that HPV may be involved in the development of SNP. But the high risk HPV is not important in malignant transformation. More studies are needed to elucidate the possible etiologic mechanism between HPV, inverted papilloma, and squamous cell carcinoma. PMID:28620639

Background Modest survival rates are published for treatment of oral squamous cell carcinoma (OSCC) using conventional approaches. Few cohort studies are available for transoral resection of OSCC. Methods Analysis for recurrence, survival, and prognosis of patients with OSCC treated with transoral laser microsurgery (TLM) ± neck dissection was obtained from a prospective database. Results Ninety-five patients (71 patients had stages T1–T2 and 24 had stages T3–T4 disease) with minimum follow-up of 24 months met criteria and demonstrated negative margins in 95%. Five-year local control (LC) and disease-specific survival (DSS) were 78% and 76%, respectively. Surgical salvage achieved an absolute final locoregional control of 92%. Immune compromise and final margins were prognostic for LC, whereas T classification, N classification, TNM stage, comorbidity, and perineural invasion were also significant for DSS. Conclusion We document a large series of patients with OSCC treated with TLM, incorporating T1 to T4 primaries. A significant proportion of stage III/IV cases demonstrates feasibility of TLM in higher stages, with final margin positivity of 5%, LC greater than 90%, and comparable survival outcomes.

Purpose: The aim of this study was to compare the clinicopathologic prognostic factors between patients who underwent lung resection for adenocarcinoma (AD) and those with squamous cell carcinoma (SQ). Methods: A database of patients with lung AD or SQ who underwent surgery with curative intent in our department from January 2008 to December 2014 was reviewed. Associations between various clinicopathologic factors, postsurgical recurrence-free survival (RFS), and overall survival (OS) were analyzed to find significant prognostic factors. Results: A total of 537 lung cancer patients (AD, 434; SQ, 103) were included in this study. Although RFS was similar in patients with AD and SQ, OS was significantly poorer in those with SQ. Multivariate analysis in patients with AD revealed that age (≥69 vs. <69), lymphatic invasion, and histologic pleural invasion (p0 vs. p1–3) were associated with RFS, while gender and pleural invasion were associated with OS. In SQ, however, smoking, clinical stage, and pulmonary metastasis were associated with RFS in the multivariate analysis. Conclusion: Since significant postoperative prognostic factors are quite different between lung AD and SQ, these two histologic types should be differently analyzed in a clinical study.

Background Protein regulator of cytokinesis-1 (PRC1) has been shown to participate in the completion of cytokinesis, and it is dysregulated in cancer processes. However, its relevance in lung squamous cell carcinoma (SCC) remained largely unknown. We aimed to study the expression pattern of PRC1 and assess its clinical significance in lung SCC. Methods PRC1 protein expression in human lung SCC and adjacent normal lung tissues was detected by immunohistochemistry. PRC1 expression was assessed in association with clinicopathological features and clinical outcomes of lung SCC patients. Results In lung SCC tissues, PRC1 protein expression was significantly higher than those in paired normal lung tissues. The lung SCC patients with PRC1 overexpression had an advanced pathological stage (TNM stage), positive lymph node metastasis, and a shorter overall survival (OS) time more frequently than patients with low PRC1 expression. Additional, PRC1 expression was also shown to be poor as a prognostic factor for OS in patients with lung SCC. Conclusions Our study indicated that aberrant expression of PRC1 may point to biochemical recurrence in lung SCC. This highlights its potential as a valuable prognostic marker for lung SCC.

To analyze our surgical management and the result of squamous cell carcinoma (SCC) of vulva. Retrospectively, we collected 38 cases of SCC; 17 cases of them were early SCC and 21 cases were locally advanced. The patients underwent primary surgery. The survival was estimated using Kaplan-Meier analysis and the log rank test. The mean age was 60.78 years. Total vulvectomy was performed in all patients. Superficial and deep incision of bilateral inguinal lymphadenectomy was performed by separates incisions for SCC infiltrating more than 1mm. The average tumor size was 53 mm (10 to 140mm). Morbidity was 42.1%. Lateral resection margin ≥8mm was obtained in 57.1%. Eighteen patients benefited from adjuvant radiotherapy. The follow-up median was 19.4 months (6 to 61.5 month) with 05 recurrences in 12 months. The survival using the Kaplan-Meyer analysis at 5 years, was 62.1% (71.2%N- vs 46.7%N+; p = 0.13). We identified two groups for locally advanced vulva cancer. Primary surgery keeps its place. Neo adjuvant radio chemotherapy followed by surgery is the alternative treatment for locally extensive lesions. PMID:27642483

From 1970 to 1979, a group of 50 patients was treated for squamous cell carcinoma of the penis by interstitial irradiation using an afterloading technique and iridium 192 wires. The group included 9 patients with T1 tumors, 27 with T2 tumors, and 14 with T3 tumors. Forty-five patients presented with no metastatic inguinal nodes (NO), 3 patients with N1 nodes, and 2 patients had N3 nodes. After treatment, 11 patients (1 T1, 6 T2 and 4 T3) developed local recurrences. Three patients developed post-therapeutic necrosis which necessitated partial amputation in 2 cases. Eight patients developed post-therapeutic urethral stenosis, which requiredmore » surgical treatment in three of the cases. Twenty-one percent of the patients died of their disease. The authors advocate interstitial irradiation using iridium 192 wires for the treatment of non-infiltrating or moderately infiltrating squamous cell carcinoma of the penis in which the largest dimension does no exceed 4 cm. When regular follow-up can be assurred, it is reasonable to forgo prophylactic treatment of the inguinal nodes in patients presenting without groin metastasis.« less

Since 1971, a group of 22 adult patients with squamous cell carcinoma of the penis have been treated by iridium 192 wire implants. There were 6 T1 tumors, 14 T2 tumors and 2 T3; only one patient (T3) presented with local failure after implant. Local necrosis occurred in 2 patients without local tumoral recurrence, but was sufficient enough to warrant amputation. Thus 19/22 (86%) patients were locally cured with penile conservation. In these patients the most frequent posttherapeutic complication is chronic urethral stenosis (9/19 patients, 47%) requiring repeated instrumental dilations. Four patients presented with initial inguinal mestastatic nodes; only onemore » was cured by radiosurgical treatment. Among patients without metastatic nodes at the time of diagnosis, none had delayed metastatic nodes. Three patients died of nodal evolution, 5 patients died of intercurrent disease without evidence of disease and 14 are now alive and NED. It appears that iridium 192 wire implant is the most effective conservative treatment of invasive squamous cell carcinoma of the penis; however, these results confirm that no particular treatment is required for inguinal nodal areas for patients who initially present with no disease.« less

From 1/1985 to 7/1993, 18 patients underwent endoscopic photodynamic therapy (PDT) for early stage esophageal squamous cell carcinoma -- as two patients had two synchronous esophageal cancers, 20 lesions were treated. Tumors were staged as Tis in 7 cases and T1 in 13. The average light energy delivered was 50 J/cm2 and 70 J/cm2 for the treatment of Tis and T1, respectively. To obtain a more uniform distribution of laser light in 12 cases the irradiation was performed through the wall of a transparent tube previously placed over the endoscope and advanced into the stomach. The overall results show a complete response in 14/20 (70%) tumors. Three patients developed a local recurrence, 6, 12, and 14 months after therapy. After a follow-up of 5 to 75 months, there was no evidence of disease in 10/18 patients (56%). The actuarial survival rate was 95%, 79%, and 26% at 1, 3, and 5 years, respectively. Complications were skin reaction in one patient and esophageal stenosis at the treatment site, that gradually responded to endoscopic bougienage, in 2 patients. Endoscopic PDT proved to be safe and effective in the treatment of superficial carcinoma of the esophagus.

Gallic acid is a polyphenolic compost appointed to interfere with neoplastic cells behavior. Evidence suggests an important role of leptin in carcinogenesis pathways, inducing a proliferative phenotype. We investigated the potential of gallic acid to modulate leptin-induced cell proliferation and migration of oral squamous cell carcinoma cell lines. The gallic acid effect on leptin secretion by oral squamous cell carcinoma cells, as well as the underlying molecular mechanisms, was also assessed. For this, we performed proliferation, migration, immunocytochemical and qPCR assays. The expression levels of cell migration-related genes (MMP2, MMP9, Col1A1, and E-cadherin), angiogenesis (HIF-1α, mir210), leptin signaling (LepR, p44/42 MAPK), apoptosis (casp-3), and secreted leptin levels by oral squamous cell carcinoma cells were also measured. Gallic acid decreased proliferation and migration of leptin-treated oral squamous cell carcinoma cells, and reduced mRNA expression of MMP2, MMP9, Col1A1, mir210, but did not change HIF-1α. Gallic acid decreased levels of leptin secreted by oral squamous cell carcinoma cells, accordingly with downregulation of p44/42 MAPK expression. Thus, gallic acid appears to break down neoplastic phenotype of oral squamous cell carcinoma cells by interfering with leptin pathway. Copyright © 2017 Elsevier GmbH. All rights reserved.

Radiotherapy and chemotherapy are targeted primarily at rapidly proliferating cancer cells and are unable to eliminate cancer stem cells in the G0 phase. Thus, these treatments cannot prevent the recurrence and metastasis of cancer. Understanding the mechanisms by which cancer stem cells are maintained in the dormant G0 phase, and how they become active is key to developing new cancer therapies. The current study found that the anti-cancer drug 5-fluorouracil, acting on the oral squamous cell carcinoma KB cell line, selectively killed proliferating cells while sparing cells in the G0 phase. Bisulfite sequencing PCR showed that demethylation of the Sox2 promoter led to the expression of Sox2. This then resulted in the transformation of cancer stem cells from the G0 phase to the division stage and suggested that the transformation of cancer stem cells from the G0 phase to the division stage is closely related to an epigenetic modification of the cell.

MicroRNAs (miRs) are expected to serve as prognostic tools for cancer. However, many miRs have been reported as prognostic markers of recurrence or metastasis in oral squamous cell carcinoma patients. We aimed to determine the prognostic markers in early-stage tongue squamous cell carcinoma (TSCC). Based on previous studies, we hypothesized that miR-10a, 10b, 196a-5p, 196a-3p, and 196b were prognostic markers and we retrospectively performed miR expression analyses using formalin-fixed paraffin-embedded sections of surgical specimens. Total RNA was isolated from cancer tissues and adjacent normal tissue as control, and samples were collected by laser-capture microdissection. After cDNA synthesis, reverse transcription-quantitative polymerase chain reaction was performed. Statistical analyses for patient clinicopathological characteristics, recurrence/metastasis, and survival rates were performed to discern their relationships with miR expression levels, and the 2−ΔΔCq method was used. miR-196a-5p levels were significantly upregulated in early-stage TSCC, particularly in the lymph node metastasis (LNM) group. The LNM-free survival rate in the low miR-196a-5p ΔΔCq value regulation group was found to be lower than that in the high ΔΔCq value regulation group (P=0.0079). Receiver operating characteristic analysis of ΔΔCq values revealed that miR-196a-5p had a P-value=0.0025, area under the curve=0.740, and a cut-off value=−0.875 for distinguishing LNM. To our knowledge, this is the first study to examine LNM-related miRs in early-stage TSCC as well as miRs and ‘delayed LNM’ in head and neck cancer. miR-196a-5p upregulation may predict delayed LNM. Our data serve as a foundation for future studies to evaluate miR levels and facilitate the prediction of delayed LNM during early-stage TSCC, which prevent metastasis when combined with close follow-up and aggressive adjuvant therapy or elective neck dissection. Moreover, our data will serve as a foundation for future studies to evaluate whether miR-196a-5p can serve as a therapeutic marker for preventing metastasis. PMID:29434944

Inefficient differentiation response to cell cycle stress leads to genomic instability and malignant progression of squamous carcinoma cells

Squamous cell carcinoma (SCC) or epidermoid cancer is a frequent and aggressive malignancy. However in apparent paradox it retains the squamous differentiation phenotype except for very dysplastic lesions. We have shown that cell cycle stress in normal epidermal keratinocytes triggers a squamous differentiation response involving irreversible mitosis block and polyploidisation. Here we show that cutaneous SCC cells conserve a partial squamous DNA damage-induced differentiation response that allows them to overcome the cell division block. The capacity to divide in spite of drug-induced mitotic stress and DNA damage made well-differentiated SCC cells more genomically instable and more malignant in vivo. Consistently, in a series of human biopsies, non-metastatic SCCs displayed a higher degree of chromosomal alterations and higher expression of the S phase regulator Cyclin E and the DNA damage signal γH2AX than the less aggressive, non-squamous, basal cell carcinomas. However, metastatic SCCs lost the γH2AX signal and Cyclin E, or accumulated cytoplasmic Cyclin E. Conversely, inhibition of endogenous Cyclin E in well-differentiated SCC cells interfered with the squamous phenotype. The results suggest a dual role of cell cycle stress-induced differentiation in squamous cancer: the resulting mitotic blocks would impose, when irreversible, a proliferative barrier, when reversible, a source of genomic instability, thus contributing to malignancy.

The aim of this study is to investigate the effects of cold atmospheric pressure plasma (CAP)-induced radicals on the epidermal growth factor receptor (EGFR), which is overexpressed by oral squamous cell carcinoma, to determine the underlying mechanism of selective killing. CAP-induced highly reactive radicals were observed in both plasma plume and cell culture media. The selective killing effect was observed in oral squamous cell carcinoma compared with normal human gingival fibroblast. Degradation and dysfunction of EGFRs were observed only in the EGFR-overexpressing oral squamous cell carcinoma and not in the normal cell. Nitric oxide scavenger pretreatment in cell culture media before CAP treatment rescued above degradation and dysfunction of the EGFR as well as the killing effect in oral squamous cell carcinoma. CAP may be a promising cancer treatment method by inducing EGFR dysfunction in EGFR-overexpressing oral squamous cell carcinoma via nitric oxide radicals.

YM155, a small molecule inhibitor of survivin, has been studied in many tumors. It has been shown that YM155 inhibited oral squamous cell carcinoma through promoting apoptosis and autophagy and inhibiting proliferation. It was found that YM155 also inhibited the oral squamous cell carcinoma-mediated angiogenesis through the inactivation of the mammalian target of rapamycin pathway. Rapamycin, a mammalian target of rapamycin inhibitor, played an important role in the proliferation and angiogenesis of oral squamous cell carcinoma cell lines. In our study, cell proliferation assay, transwell assay, tube formation assay, and western blot assay were used to investigate the synergistic effect of rapamycin on YM155 in oral squamous cell carcinoma. Either in vitro or in vivo, rapamycin and YM155 exerted a synergistic effect on the inhibition of survivin and vascular endothelial growth factor through mammalian target of rapamycin pathway. Overall, our results revealed that low-dose rapamycin strongly promoted the sensitivity of oral squamous cell carcinoma cell lines to YM155.

Esophageal squamous cell carcinoma is a commonly malignant tumor of digestive tract with poor prognosis. Previous studies suggested that forkhead box F2 ( FOXF2) could be a candidate gene for assessing and predicting the prognosis of human cancers. However, the relationship between FOXF2 promoter methylation and the prognosis of esophageal squamous cell carcinoma remained unclear. Formalin-fixed, paraffin-embedded esophageal squamous cell carcinoma tissues of 135 esophageal squamous cell carcinoma patients were detected for FOXF2 promoter methylation status by methylation-specific polymerase chain reaction approach. DNA methylation results were evaluated with regard to clinicopathological features and overall survival. Our study confirmed that FOXF2 promoter hypermethylation could independently predict a poorer overall survival of esophageal squamous cell carcinoma patients ( p = 0.002), which was consistent with the data mining results of the data from 82 esophageal squamous cell carcinoma patients in The Cancer Genome Atlas datasets ( p = 0.036). In addition, no correlation was found between FOXF2 promoter methylation and other clinic pathological parameters (age, gender, differentiation, lymph node metastasis, stage, cutting edge, vascular invasion, smoking behavior, and drinking history). In conclusion, FOXF2 methylation might be a useful prognostic biomarker for esophageal squamous cell carcinoma patients.

Human papillomavirus (HPV) has been implicated in the pathogenesis of a subset of oropharyngeal squamous cell carcinoma. As a result, traditional paradigms in relation to the management of head and neck squamous cell carcinoma have been changing. Research into HPV-related oropharyngeal squamous cell carcinoma is rapidly expanding, however many molecular pathological and clinical aspects of the role of HPV remain uncertain and are the subject of ongoing investigation. A detailed search of the literature pertaining to HPV-related oropharyngeal squamous cell carcinoma was performed and information on the topic was gathered. In this article, we present an extensive review of the current literature on the role of HPV in oropharyngeal squamous cell carcinoma, particularly in relation to epidemiology, risk factors, carcinogenesis, biomarkers and clinical implications. HPV has been established as a causative agent in oropharyngeal squamous cell carcinoma and biologically active HPV can act as a prognosticator with better overall survival than HPV-negative tumours. A distinct group of younger patients with limited tobacco and alcohol exposure have emerged as characteristic of this HPV-related subset of squamous cell carcinoma of the head and neck. However, the exact molecular mechanisms of carcinogenesis are not completely understood and further studies are needed to assist development of optimal prevention and treatment modalities.

Polo-like kinase 1 (PLK1) has been suggested to serve as an oncogene in most human cancers. The aim of our study is to present more evidence about the clinical and prognostic value of PLK1 in lung squamous cell carcinoma patients. The status of PLK1 was observed in lung adenocarcinoma, lung squamous cell carcinoma, and normal lung tissues through analyzing microarray dataset (GEO accession numbers: GSE1213 and GSE 3627). PLK1 mRNA and protein expressions were detected in lung squamous cell carcinoma and normal lung tissues by using quantitative real-time PCR (qRT-PCR) and immunohistochemistry. In our results, the levels of PLK1 in lung squamous cell carcinoma tissues were higher than that in lung adenocarcinoma tissues. Compared with paired adjacent normal lung tissues, the PLK1 expression was increased in lung squamous cell carcinoma tissues. Furthermore, high expression of PLK1 protein was correlated with differentiated degree, clinical stage, tumor size, lymph node metastasis, and distant metastasis. The univariate and multivariate analyses showed PLK1 protein high expression was an unfavorable prognostic biomarker for lung squamous cell carcinoma patients. In conclusion, high expression of PLK1 is associated with the aggressive progression and poor prognosis in lung squamous cell carcinoma patients. PMID:28724602

Abundant squamous cells are rarely encountered in thyroid FNA with only few case reports noted in the literature. Their presence and cytologic features may pose a diagnostic dilemma and challenges for proper classification and follow-up. We intend to gain more insight into the frequency of this finding and its clinical significance. Our electronic records were searched over 16 years to reveal 15 thyroid FNAs with abundant squamous cells. The available cytology and surgical resection slides were reviewed and radiologic records and clinical follow-up was documented. Only 15 out of 8811 thyroid FNAs from our department contained predominantly squamous cells (0.17%) of which two were interpreted as nondiagnostic, four as atypical, eight as benign, and one malignant. Surgical follow-up was available in eight cases only with benign lesions representing the majority of the cases (squamous metaplasia in Hashimoto thyroiditis, benign epidermoid/branchial cleft or thyroglossal duct cysts, and one case squamous cell carcinoma). The cases without surgical resection were stable on subsequent ultrasound studies. Thyroid aspirates with predominance of squamous cells cannot be classified in the current Bethesda categories. Even when interpreted as atypical or equivocal, the squamous cells present in our small case series were mostly benign. The only malignant case was easily identified cytologically because of its higher degree of differentiation. The most common pitfall for atypical squamous cells in these aspirates was squamous metaplasia in the setting of Hashimoto thyroiditis and degenerative changes. Diagn.

This retrospective study aimed to investigate the impact of peritumoral retraction clefts (RC) and tumor-associated tissue eosinophilia (TATE) as predictors of overall survival (OS) in oral squamous cell carcinoma (OSCC) patients. Their relationships with tumor-factors were also examined. Eighty-seven OSCC cases (pTNM: I + II/III + IV; 32/55), post-curative surgery, comprised the study cohort. Three observers independently estimated the percent RC semi-quantitatively in the selected tumor sections. Additionally, stromal eosinophils were counted in ten consecutive high-power fields of intratumoral and peritumoral regions to evaluate the corresponding TATE. The percent RC ranged between 0% -90% (Mean ± SD: 16 ± 24%; Median: 5%). The stromal eosinophils were greater in peritumoral as compared to intratumoral region. The events of death and tumor recurrence were reached in 16 (18.4%) and 36 (41%) cases respectively. The 3-years OS was 69% [Median OS: 1880 days; Mean follow up: 471(Range; 36-1880) days]. Increased percent RC exhibited relationship with pathologic stage (pTNM III&IV), primary tumor (pT III&IV), tumor depth > 4 mm and categorical tumor recurrence. Additionally, peritumoral eosinophilic infiltrates increased with increasing tumor depths and muscle invasion. Kaplan-Meier curves revealed significantly reduced OS in OSCC cases exhibiting: increased percent RC (>2.5%), mild -moderate/absent intratumoral TATE (versus intense TATE) or categorical tumor recurrence. In subsequent multivariate tests, all the three variables retained significance. Additionally, intraclass correlation coefficient demonstrated acceptable internal consistency for the observers who estimated percent RC. In conclusion, RC and intratumoral TATE proved to be independent predictors of OS in our OSCC cohort. Additionally, increased percent RC pointed towards aggressive tumor behaviour.

Squamous cell carcinoma (SCC) antigen, a tumor marker of squamous cell carcinoma, is also increased in several nonmalignant skin lesions, e.g. pemphigus. The aim of the present investigation was to determine if tumor necrosis factor-alpha (TNF-alpha), one of the important environmental factors, stimulated the production of SCC antigen in the normal squamous cells. The exposure of normal human epidermal keratinocytes to TNF-alpha (100 IU/ml) for 72 h greatly increased the SCC antigen production. The stimulatory effect of TNF-alpha (1,000 IU/ml) on the production of SCC antigen was also observed in the normal squamous epithelium tissue. These results would be helpful for understanding the increase of SCC antigen in several nonmalignant skin disorders.

We have previously indicated that EGFR has a role in carcinogenesis in a subgroup of sinonasal squamous cell carcinomas (SNSCC). In addition, EGFR activates 2 of the most important intracellular signalling pathways: PI3K/pAKT/mTOR/pS6 and MAP pathway kinases. The objective of this study was to evaluate the involvement of the EGFR/PI3K/pAKT/mTOR/pS6 pathway and its relationship with clinical-pathological parameters and follow-up of sinonasal squamous cell carcinoma. The immunohistochemical expression of different components of the PI3K/AKT/mTOR/pS6 pathway and its relationship with various clinical-pathological parameters was studied in a series of 54 patients with SNSCC. Loss of PTEN expression was observed in 33/54 cases (61%) and pAKT, mTOR and pS6 pre-expression was observed in 19/54 cases (35%), 8/54 cases (15%), and 47/54 cases (87%), respectively. Loss of PTEN expression was related to intracranial invasion and development of regional metastases (p=0.005). Overexpression of pS6 was associated with a decrease in survival (p=0.008), presence of local recurrences (p=0.055), and worsening of overall prognosis (p=0.007). No significant relationships were observed between pAKT and mTOR expression and the clinicopathological parameters studied. Alterations in the expression of EGFR/PI3K/pAKT/mTOR/pS6 pathway components are common in a subgroup of SNSCC. This study reveals that the absence of pS6 overexpression is associated with better clinical outcomes. Therefore, pS6 expression could be considered as an unfavourable prognostic marker.

Conejo-Mir, J S; Moreno, J C; Camacho, F

1997-06-01

Chronic x-ray dermatitis in professionals is a frequent problem for doctors in our country due to the fact that many of them widely used radiotherapy without any protection 15-20 years ago. Surgery has been the most accepted treatment, though it generally decreases hand function. Up to now, cryosurgery was not usually considered as a possible treatment if the lesions were located on fingers. In this study, the advantages of cryosurgery for the treatment of professional chronic radiodermatitis with incipient pretumoral lesions are emphasized. Cryosurgery was performed on six patients affected with chronic professional radiodermatitis that showed keratomas and ulcerations, using both spray (keratomas) and a probe 0.5 cm in diameter (ulcerations, in situ squamous cell carcinoma). Nerve block anesthesia with mepivacaine 1% was used in all cases. Before the treatment, all suspected lesions were biopsied; if invasive squamous cell carcinoma was revealed in the dermatopathological study, the patient was rejected. Variables such as blister and necrosis formation, pain, and achromatic, sensibility, and mobility disorders were studied. The follow-up period was 2 years. Immediate postoperative results showed great pain and blistering in all cases. Residual achromias were observed early postoperatively in all cases, but were repigmented 1 year after therapy in four cases (66%). Sensory alterations (hypo- and hyperthesias) were found in four cases (66%) 1 month after treatment, although this complication was not observed 6 months after treatment. Finger mobility was perfect in all cases 2 months after treatment, and there was no recurrence in any case after 2 years of follow-up. We believe cryosurgery must be considered as an excellent treatment for professional chronic radiodermatitis with keratomas, ulcerations, and incipient squamous cell carcinomas. Its use may prevent further dramatic surgical treatment, like amputations, allowing the preservation of finger function.

To evaluate the screening efficacy and importance of atypical squamous cells and atypical glandular cells in predicting subsequent cervical cancer risk. This national cohort study in Taiwan analyzed associations between Pap test screening frequency and findings in 1995-2000 and subsequent risk of squamous cell carcinoma and adenocarcinoma after 2002. Women aged 30 years or older in 1995 without a cervical cancer history were included. Multivariate-adjusted hazard ratios and their 95% confidence intervals (CIs) were assessed using Cox regression analysis. During a total follow-up of 31,693,980 person-years in 2002-2008, 9,471 squamous cell carcinoma and 1,455 adenocarcinoma cases were newly diagnosed, resulting in 2,067 deaths. The risk of developing and dying from squamous cell carcinoma decreased significantly with increasing attendance frequency between 1995 and 2000 (all P values for trend<.001). Women who attended more than three screenings in 1995-2000 had 0.69-fold and 0.35-fold decrease in incidence and mortality of adenocarcinoma, respectively, compared with women who never attended any screenings. Abnormal cytologic findings were significant predictors of the incidence and mortality of cervical cancers. The adjusted hazard ratio (95% CI) of developing squamous cell carcinoma was 29.94 (22.83-39.25) for atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions, and the adjusted hazard ratio (95% CI) of developing adenocarcinoma was 49.43 (36.49-66.97) for atypical glandular cells. Significant reductions in cervical adenocarcinoma occurred in women who attend three or more annual screenings in 6 years. High-grade atypical squamous cells and atypical glandular cells are important predictors of subsequent adenocarcinoma and squamous cell carcinoma. II.

Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

Proliferative verrucous leukoplakia is a multifocal and progressive lesion of the oral mucosa, with unknown etiology, and commonly resistant to all therapy attempts with frequent recurrences. It is characterized by a high rate of oral squamous cell carcinoma and verrucou carcinoma transformations. To analyze the studies about Proliferative verrucous leukoplakia and develop a concise update. A Pubmed search identifying studies (laboratory research, case series and reviews of literature) that examined patients with Proliferative verrucous leukoplakia was realized. There are not enough studies about Proliferative verrucous leukoplakia in the literature. The few found studies not present a consensus about its etiology and diagnosis criteria. Although several treatment strategies have been proposed, most of them still show a high recurrence rate. More research about Proliferative verrucous leukoplakia is necessary to understand and treat this disease. Copyright © 2017 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Sixty-five patients with neoplastic diseases of the larynx, oral cavity, pharynx, and skin have been treated with PDT with followup to 56 months. Patients with carcinoma in situ and T1 carcinomas obtained a complete response after one PDT treatment. All but two have remained free of disease. Eight patients with T2 and T3 carcinomas treated with PDT obtained a complete response, but they all recurred locally. This is due to the inability to adequately deliver laser light to the depths of the tumor bed. five patients with massive neck recurrences of squamous cell carcinomas were treated with intraoperative adjuvant PDT following tumor resection. Only one developed recurrence with 24- month followup. PDT is highly effective for the curative treatment of early carcinomas (CIS, T1) of the head and neck. Also, intraoperative adjuvant PDT may increase cure rates of large infiltrating carcinomas of the head and neck.

Early detection, clinical management and disease recurrence monitoring are critical areas in cancer treatment in which specific biomarker panels are likely to be very important in each of these key areas. We have previously demonstrated that levels of alpha-2-heremans-schmid-glycoprotein (AHSG), complement component C3 (C3), clusterin (CLI), haptoglobin (HP) and serum amyloid A (SAA) are significantly altered in serum from patients with squamous cell carcinoma of the lung. Here, we report the abundance levels for these proteins in serum samples from patients with advanced breast cancer, colorectal cancer (CRC) and lung cancer compared to healthy controls (age and gender matched) using commercially available enzyme-linked immunosorbent assay kits. Logistic regression (LR) models were fitted to the resulting data, and the classification ability of the proteins was evaluated using receiver-operating characteristic curve and leave-one-out cross-validation (LOOCV). The most accurate individual candidate biomarkers were C3 for breast cancer [area under the curve (AUC) = 0.89, LOOCV = 73%], CLI for CRC (AUC = 0.98, LOOCV = 90%), HP for small cell lung carcinoma (AUC = 0.97, LOOCV = 88%), C3 for lung adenocarcinoma (AUC = 0.94, LOOCV = 89%) and HP for squamous cell carcinoma of the lung (AUC = 0.94, LOOCV = 87%). The best dual combination of biomarkers using LR analysis were found to be AHSG + C3 (AUC = 0.91, LOOCV = 83%) for breast cancer, CLI + HP (AUC = 0.98, LOOCV = 92%) for CRC, C3 + SAA (AUC = 0.97, LOOCV = 91%) for small cell lung carcinoma and HP + SAA for both adenocarcinoma (AUC = 0.98, LOOCV = 96%) and squamous cell carcinoma of the lung (AUC = 0.98, LOOCV = 84%). The high AUC values reported here indicated that these candidate biomarkers have the potential to discriminate accurately between control and cancer groups both individually and in combination with other proteins.

Correlation between the expression of STK33 and the pathology of lung cancer was investigated, to explore its effects on prognosis. Hundred and two lung cancer patients diagnosed by pathological examinations were randomly selected in Shanghai Jiao Tong University Affiliated Sixth People's Hospital from February, 2012 to February, 2017 to serve as observation group, and the tumor tissues were collected. At the same time, 19 patients with lung benign lesions were selected and lung tissues were also collected to serve as control group. RT-qPCR was used to detect the expression of STK33 mRNA in tissues. Expression levels of STK33 protein were detected and compared by SP immunohistochemistry staining and western blot analysis. Statistical analysis was performed to analyze the correlation between STK33 expression and the pathology and prognosis of lung cancer. Results of PCR showed that expression level of STK33 gene in control group was significantly lower than that in observation group (p<0.05). The expression level of STK33 mRNA in lung adenocarcinoma and squamous cell carcinoma was lower than that in lung small cell carcinoma and large cell carcinoma (p<0.05). Western blot analysis showed that the expression level of STK33 protein in lung small cell carcinoma and large cell carcinoma was significantly higher than that in lung adenocarcinoma and squamous cell carcinoma (p<0.05). Immunohistochemistry staining showed that the positive rate of STK33 in lung large cell carcinoma (100%) and small cell carcinoma (100%) was significantly higher than that in lung adenocarcinoma (88.1%) and squamous cell carcinoma (86.2%) (p<0.05). The 5-year survival rate analysis showed that the recurrence-free survival rate and overall survival rate of STK33 gene high expression level group were significantly lower than those of low expression level group (p<0.05). The differential expression level of STK33 is related to the pathology and prognosis of lung cancer, which is of great value in clinical diagnosis and prognosis evaluation. PMID:29085482

Midkine is a heparin-binding growth factor highly expressed in various human malignant tumors. However, its role in the growth of oral squamous cell carcinoma is not well understood. In this study, we analyzed the antitumor effect of a novel midkine inhibitor (iMDK) against oral squamous cell carcinoma. Administration of iMDK induced a robust antitumor response and suppressed cluster of differentiation 31 (CD31) expression in oral squamous cell carcinoma HSC-2 cells and SAS cells xenograft models. iMDK inhibited the proliferation of these cells dose-dependently, as well as the expression of midkine and phospho-extracellular signal-regulated kinase in HSC-2 and SAS cells. Moreover, iMDK significantly inhibited vascular endothelial growth factor and induced tube growth of human umbilical vein endothelial cells in a dose-dependent fashion. These findings suggest that midkine is critically involved in oral squamous cell carcinoma and iMDK can be effectively used for the treatment of oral squamous cell carcinoma.

The neurokinin 3 receptor (NK-3R) is differentially expressed in the central nervous system including cases of human oral squamous cell carcinoma. However, the role of NK-3R signaling in oral squamous cell carcinoma is not well known. NK-3R expression in surgically resected oral squamous cell carcinoma was examined immunohistochemically and the strength of the expression was quantified. We evaluated the function of NK-3R signaling using NK-3R antagonist in human oral squamous cell carcinoma bone invasion mouse model. NK-3R was significantly expressed in tumor cells that had invaded the bone matrix compared to the oral side tumor cells. SB222200, a selective antagonist of NK-3R, significantly suppressed the radiographic osteolytic lesion and tumorigenesis. NK-3R signaling is a potential target for the treatment of oral squamous cell carcinoma in cases of bone destruction. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Kindler syndrome is a rare autosomal recessive genodermatosis characterized by trauma-induced acral blisters in infancy and childhood, photosensitivity, and progressive poikiloderma. Other clinical features include chronic erosive gingivitis, dysphagia, esophageal and urethral strictures, ectropion, and an increased risk of mucocutaneous squamous cell carcinoma. We describe a patient with Kindler syndrome associated with squamous cell carcinoma of the skin and larynx. He had squamous cell carcinoma on his left knee with simultaneous unresectable laryngeal carcinoma at the age of 43 years. The squamous cell carcinoma on his knee was excised and the laryngeal carcinoma was treated with radiation therapy. Although pathophysiology of Kindler syndrome and its frequency of association with cancer are still not fully elucidated, we speculate that long-term erosion and regeneration of mucosal and cutaneous surfaces may have induced squamous cell carcinoma on the patient's knee and larynx.

Xeroderma pigmentosum is a rare autosomal-recessive disorder that appears in early childhood. Squamous cell carcinoma is not uncommon in patients with xeroderma pigmentosum and mostly involving the face, head, neck, and scalp. However, squamous cell carcinoma of the scalp may exhibit an aggressive course. Here, we present a huge squamous cell carcinoma of the scalp in a three-years-old child with xeroderma pigmentosum. In addition, we illustrate the challenges of a child with xeroderma pigmentosum who grows up in a sunny environment where the possibility of early onset of squamous cell carcinoma is extremely high in any suspected skin lesion. In xeroderma pigmentosum patients, squamous cell carcinoma of the scalp can present early and tends to be unusually aggressive. In sunny areas, proper education to the patient and their parents about ultra-violet light protection and early recognition of any suspicious lesion could be life-saving.
