Filter by:Narrow-Band Imaging (NBI) is as sensitive as Lugol chromoendoscopy to detect oesophageal squamous cell carcinoma (SCC) and appears more specific than Lugol chromoendoscopy in expert centres but its specificity in current practice is not known. This study aimed to prove the superiority of NBI specificity over Lugol chromoendoscopy to detect oesophageal SCC and high-grade dysplasia (HGD) in current practice (including tertiary care centres, local hospitals and private clinics).
The purpose of this study is to assess the efficacy and safety of intratumoral (IT) ulevostinag PLUS pembrolizumab (MK-3475) compared to pembrolizumab alone as a first line treatment of adults with metastatic or unresectable, recurrent head and neck squamous cell carcinoma (HNSCC). The primary study hypotheses are that IT ulevostinag in combination with pembrolizumab results in a superior Objective Response Rate (ORR), per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), compared to pembrolizumab alone: 1. In participants with a tumor that has a programmed cell death-ligand 1 (PD-L1) Combined Positive Scoring (CPS) ≥ 1, and 2. In participants with a tumor that has a PD-L1 CPS ≥ 20.
This phase I/II trial studies the side effects and how well bintrafusp alfa and stereotactic body radiation therapy work in treating patients with head and neck squamous cell cancer that has come back (recurrent) or has occurred after having cancer in the past (second primary). Immunotherapy with bintrafusp alfa may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving bintrafusp alfa and stereotactic body radiation therapy may help to control recurrent head and neck squamous cell cancer.
Background: Pilonidal sinus is a very common disease. Malignant transformation occurs in 0,1% of patients. The investigators present a case of squamous cell carcinoma arised from recurrent pilonidal disease, managed by multimodal treatment. Case presentation: The investigators present a 70-year-old man with chronic pilonidal sinus. Inflammation had worsened in previous months and exploration revealed a large ulcerative mass which biopsy showed a squamous cell carcinoma. CT scan and MRI imaging showed tumoral invasion of the coccyx and both gluteus major muscles. Neoadjuvant radiotherapy, chemotherapy as radiosensitizer and surgery with intraoperative radiotherapy was decided in the multidisciplinary tumor committee. Post neoadjuvant therapy MRI showed partial response with a decrease of the mass but persistence of the coccyx infiltration. Surgery consisted in en-bloc resection of the tumor with presacral tissues, coccyx and partial gluteal resection. Intraoperative radiotherapy was administered over the sacrum and in the bed of the coccyx resection. One week later, reconstructive surgery was practiced using a latissimus dorsi free flap, advancement of gluteal flaps and skin graft. Histological examination showed no residual tumor. The patient is currently asymptomatic and he has a satisfactory quality of life. Conclusions: Although squamous cell carcinoma is rare, it must be suspected in patients with recurrent pilonidal disease. Diagnosis is done by histological examination of biopsies. This type of tumors have a high local recurrence rate. The investigators propose a multimodal treatment that includes neoadjuvant radiotherapy and chemotherapy as radiosensitizer and surgery plus intraoperative radiotherapy with the aim to decrease local recurrence rate.

Phase III Study to Investigate the Efficacy and Safety of CS1001 or Placebo in Combination with FP as First-Line Therapy in Subjects with Unresectable Locally Advanced, Recurrent or Metastatic Esophageal Squamous Cell Carcinoma
Squamous cell carcinomas (SCC) are the second most common skin cancer in humans. The incidence of SCCs in the USA in 2012 was estimated at 700,000 casesSCCs have a metastatic course in 3% to 5% of cases that is of poor prognosis. In men, the SCCs of the scalp represent the most frequent location of the head and neck, the 3rd location of the whole body. The SCCs of the scalp are more undifferentiated than in other locations. In addition, actinic keratoses of scalp, precursors of SCC, are more resistant to treatment than in other areas. These particularities of the SCCs of the scalp suggest the existence of specific factors at the epidermis level of the scalp. UV-induced damage to DNA is the defining event in skin photocarcinogenesis. It has already been shown that DNA damage induced by UV and the kinetics of repair of this damage may vary with age or phototype of patients, but the topographic variation of DNA damage has never been studied, although it is known that gene expression in skin cells may differ from one region of the body to another. the hypothesis is therefore that the particular characteristics of KAs and SCCs at the scal level could be explained by an increased sensitivity to UV-induced damage. It is planned to study UV-induced damage and its repair at the scalp level in humans compared to the forearm.
Backgrounds Squamous cell carcinoma of the oral cancer (OSCC) is the sixth most common malignancy. Surgery is the mainstay of treatment for oral cancers. In locally advanced and unresectable oral cancer, surgery presents challenges primarily because the head and neck region have many critical structures that can be damaged by tumor or treatment. Damage to the critical structures can result in significant structural, cosmetic and functional deficits that negatively impact quality of life. Use of NC was found to achieve resectability in 39% of locally advanced unresectable oral cancers. Patil et al. reported response rate with the three drugs regimen (TPF) for NC was 32% and 27,37% for two drugs regimen (TP). The overall response rate in the TPF group was significantly higher than that in the PF group, both in the induction-chemotherapy phase and after locoregional therapy (33,3% vs 19,9%, p = 0,004). Chemoresistancy has become the challenge in OSCC treatment affecting tumor response to chemotherapy. Hypoxic microenvironment found in OSCC is marked by the high expression of HIF-1α. CD44 and CD133 as a cancer stem cells marker in head and neck (HNSCC) and miR-210 known as hypoxamiR has been reported to contribute chemoresistancy. As hypoxia inarguably one of the main causes of chemoresistancy, it is agreeable to use melatonin as an antioxidant to reduce the hypoxic condition in tumor microenvironment. Melatonin, a potent endogenous antioxidant agent is proven to have an oncostatic effect, was given in expect to reduce the tumor hypoxic condition so that it would increase the tumor response on NC. Majority of the clinical study use oral melatonin given once daily in 20 mg dose as the minimal dose to yield anti-tumor effects. The purpose of this study is to prove the effectiveness of melatonin to increase clinical response in locally advanced OSCC patients when treated with NC. The effect of melatonin in reducing tumor hypoxia will be seen through its effect in decreasing the gene expressions of HIF-1α, miR-210, CD44, and CD133. Methods Study Design This study is a double blind, randomized clinical trial using placebo as comparison running from June 2017 to July 2018 . Locally advanced OSSC (stage IVA and IVB) patients that will receive NC were included in the study. Fifty patients treated at two centres (RSCM and RSKD) were randomly allocated into two arms. Twenty-five patients received melatonin combined with three regiment NC (Taxane, Cisplatin, and 5-FU) and the other received placebo with NC. However only 25 out of 50 patients had completed the study protocol (13 patients in melatonin arm and 12 in placebo arm) Evaluation of Clinical Response The clinical response were assessed by evaluating pre-treatment and post treatment MRI with the aid of RECIST 1.1. First, it is necessary to estimate the overall tumor burden at baseline (target and non-target lesion) and use this as a comparator for subsequent measurement. The tumor response then being determined according to the definition criteria according to RECIST 1.1, as follows: Complete response (CR) is the disappearance of all target lesions. Partial response (PR) means there is at least 30% decrement in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive disease (PD) means there is at least a 20% increment in the sum of diameters of target lesions or an absolute increment of at least 5 mm. Stable disease (SD) is when there is neither a sufficient shrinkage nor sufficient increment of target lesion. Patients who categorized as PR and CR undergone surgery while those with SD and PD undergone core biopsy. Genes expression examination The primer for HIF-1α miR210, CD44, and CD133 genes amplification was design using a Primer Quest Tool IDT software. The total sequence of each gene attained from GenBank data source: National Centre for Biotechnology Information (NCBI). The steps of gene expression examination are RNA isolation, cDNA synthesis, and absolute quantification qPCR. qPCR result was analyzed based on the gene expression concentration compare to the pre-determined standard curve (positive control) of each genes. Statistical analysis The data was analysed with statistics software SPSS 20. Saphiro Wilk was used to test data normal distribution. Data with normal distribution and with p > 0,05 presented in mean +- standard deviation (SD). Data with abnormal data distribution presented in median (minimal and maximal value). The statistical difference of gene concentration level (numerical data) between melatonin and placebo was analysed using normality test of Saphiro Wilk. Data with normal distribution was tested using unpaired-T test, while data with abnormal distribution was tested using Mann Whitney. Statistically significant different stated as p < 0,05.
