Squamous cell carcinoma (SCC) of the urethra is a rare malignancy, comprising less than 1% of all malignancies. The annual age-adjusted incidence of urethral SCC is 4.3 per million in men and 1.5 per million in women. Due to the rarity of the disease, there are a limited number of prospective randomized controlled trials to evaluate the optimal management of locally advanced urethral SCC. Here, we present the case of a 47-year-old man with stage IIIB urethral squamous cell cancer that showed complete clinical and pathologic response to neoadjuvant chemoradiation with only 5-flurouracil after incomplete response to traditional chemotherapy with paclitaxel, ifosfamide, and cisplatin (TIP).

The histology and immunohistochemistry (IHC) of primary and metastatic diseases from a human papilloma virus- (HPV-) related anal squamous carcinoma (ASCC) would typically demonstrate the same histology as an HPV-related oropharyngeal squamous carcinoma (OPSCC). However, determining whether a site of squamous cell carcinoma represents distant metastatic ASCC versus a metastatic HPV-related metastasis from an OPSCC to a regional lymph node carries profound prognostic and therapeutic implications. A patient with a history of locally advanced ASCC treated with standard concurrent radiation therapy and chemotherapy in 2015 is described. In 2018, an enlarged supraclavicular lymph node was excised demonstrating squamous cell carcinoma and radiographic staging revealed no other areas suspicious for malignancy. Direct laryngoscopy with operating telescope and biopsies demonstrated squamous cell carcinoma at the tongue base. Described here are assays that might be considered in distinguishing between whether a focus distant from a previously identified ASCC represents metastatic disease or instead a separate primary HPV-related cancer.

Abstract Objective Neoadjuvant chemoradiation (CRT) using paclitaxel and carboplatin has significantly improved the survival rates in carcinoma esophagus, especially in squamous cell carcinoma (SCC). This regimen has not been adequately explored prospectively as a definitive CRT strategy. Our aim was to evaluate the efficacy, toxicity, and compliance to this regimen in a prospective setting in locally advanced esophageal SCC. Materials and Methods Patients with locally advanced esophageal SCC were planned for definitive CRT by using weekly paclitaxel 50 mg/m2 and carboplatin area under curve 2 along with radical radiotherapy to a dose of 50.4 to 54 Gy. Treatment-related toxicity was assessed by using the common terminology criteria for Adverse Events Version 4.0, and the response was assessed by using endoscopy and computed tomography (CT) 4 to 6 weeks following CRT. The pathological response was documented for those who underwent surgery. Results Fifteen patients were included in the study, and all patients completed the planned course of radiation. The median number of chemotherapy cycles received was four. In total, 66% of the patients had delay or interruptions in chemotherapy, mostly due to neutropenia, and 66% of the patients had a clinical complete response (CR). Four patients underwent definitive esophagectomy, and the histopathology revealed pathologic CR. Overall CR rate was 80%. The median overall survival was 14 months, and 1-year survival was 57%. Conclusion Definitive CRT in esophageal SCC using weekly paclitaxel and carboplatin was relatively well tolerated with manageable toxicities and good clinical response rates. It may potentially represent a new standard of care as definitive therapy in the management of these tumors.

Abstract BackgroundEsophageal squamous cell carcinoma (ESCC) still has a poor prognosis despite the use of multidisciplinary therapy. In the locally advanced stage, neoadjuvant chemoradiotherapy (nCRT) followed by surgery might provide survival benefits to some patients. MethodsIn this study, we aimed to identify biomarker to predict tumor response against neoadjuvant chemoradiotherapy (nCRT) by next-generation sequencing (NGS).ResultsOur data showed that 464 genes was differentially expressed ESCC specimens, in which AGR2 was 2.8 fold up-regulated in the patients with Non-complete response before nCRT than complete response group. In vitro study showed that, AGR2 was significantly reduced in AGR2 knockdown CE146T/VGH, TE2, and CE48T/VGH cells. MTT assay indicated that cell viability of AGR2-knockdown TE-2 cell line significantly decreased following 2.5µM cisplatin and 3µM 5-FU treatment. Furthermore, 6µM cisplatin and 20 µM 5-FU treatment greatly decreased AGR2-knockdown-CE48T/VGH, CE146T/VGH and TE-2 cells compared to control group. We also found in AGR2-knockdown cells, that protein level of p21 was increased in comparison with the control group. ConclusionsThis study suggest that AGR-2 as a promising and potential prediction gene marker dataset for response to neoadjuvant chemoradiation in ESCC.

Primary squamous cell carcinoma (SCC) of the gallbladder is a rare malignancy of the gallbladder, accounting for less than 5% of gallbladder pathology. Initial presentation is often similar to adenocarcinoma of the gallbladder. SCC tends to be more locally aggressive, however, and possesses a worse prognosis than adenocarcinoma. We report a case of locally advanced SCC of the gallbladder.

TPS6091 Background: Patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) have low response rates to licensed second line therapies, including PD-1 inhibitors nivolumab and pembrolizumab, and represent an area of unmet clinical need. The chimeric IgG1 epithelial growth factor receptor (EGFR) monoclonal antibody cetuximab potentiates the activity of radiotherapy in locally advanced HNSCC and chemotherapy in R/M HNSCC and is also licensed with modest activity as a single agent. Cetuximab initiates Natural Killer (NK) cell antibody-dependent cell-mediated cytotoxicity (ADCC), resulting in an anti-tumour immune response and the potential to augment the activity of PD-1/PD-L1 inhibition. EACH aims to examine the safety and efficacy of the potentially synergistic interaction between cetuximab and avelumab, a fully human IgG1 anti-PD-L1 monoclonal antibody in R/M HNSCC. Methods: EACH is a randomised phase II trial preceded by a safety run-in phase. Eligible patients have histologically or cytologically confirmed measurable recurrent or metastatic squamous cell carcinoma of any site in the safety run-in phase, and HNSCC in phase II, that is considered incurable by local therapies. The safety run-in has a single arm de-escalating design, aiming to establish the safety of cetuximab with avelumab and determine the optimal dose of cetuximab within this combination. The safety run-in has a dosing schedule of avelumab (10 mg/kg) + cetuximab (500 mg/m2) intravenously every 2 weeks, with de-escalation of cetuximab to 400 mg/m2 and 300 mg/m2 if necessary. The safety run-in phase commenced recruitment in July 2018 and is ongoing. The phase II component will randomize 114 HNSCC patients between either avelumab + cetuximab at the dose determined by the safety run-in phase or avelumab (10 mg/kg) alone. Treatment will be in 4-week cycles for up to one year. The primary endpoint in the safety run-in phase is the occurrence of dose limiting toxicities, and in phase II is Disease Control Rate at 24 weeks, using iRECIST. Blood and fresh tissue will be collected for exploratory translational studies, which will focus on the identification of potential novel predictive biomarkers for response. Clinical trial information: NCT03494322.
