Carcinoma of the oesophagus including carcinoma of gastro-oesophageal junction are rapidly increasing in incidence. During recent years there have been changes in the knowledge surrounding biology of the disease progression. Identification of dysplasia in mucosal biopsies is the most reliable pathologic indicator of an increased risk of development of squamous cell carcinoma and passes through the sequence of chronic esophagitis, low-grade and high-grade dysplasia and invasive carcinoma. Although Barrett's esophagus is a precursor to esophageal adenocarcinoma and have a well described sequence of carcinogenesis: the Barrett's metaplasia-dysplasia-adenocarcinoma sequence, not all patients with this disorder require intensive surveillance. The natural history of dysplasia is poorly understood, particularly in low-risk regions, and prospective follow-up studies are needed. Adjunctive methods to improve reproducibility, such as immunostaining for alpha-methylacyl-coenzyme A racemase (AMACR), show promise, but require confirmation in larger studies. In addition, several controversial methods such as detection of p16, p53, and DNA content abnormalities may help identify patients at particularly high risk for progression to cancer, but these techniques are not yet widely available for routine clinical application. More studies are needed to define other early nonmorphologic biomarkers for risk of squamous cell carcinoma. Recent evidence regarding the importance of several histopathologically derived prognostic factors, such as circumferential resection margin status and lymph node metastases are evaluated, including lymph node micrometastases and the sentinel node concept. With the rising use of multimodal treatments for oesophageal cancer it is important that the response of the tumour to this therapy can be carefully documented by histopathology.

e16095 Background: There has been a definite histopathological shift in esophageal cancer in the West over the past few decades, with adenocarcinoma overtaking squamous cell carcinoma as the commonest type. Asian countries with a high human development index like China have also reported an increased incidence of esophageal adenocarcinoma. Data on the epidemiology of esophageal cancer in India are limited. Methods: We retrospectively evaluated the data of all patients with histologically proven esophageal cancer at Tata Memorial Hospital, from 2003 to 2018. We excluded non-squamous and non-adenocarcinoma histologies. Results: Of a total of 7,874 patients with esophageal cancer, 5,092 (64.7%) were men, for a male to female ratio of 2.5:1. The median age was 57 years (IQR, 50-65); 4,465 (56.7%) were below 60 years old. Of the 4912 patients in whom a history of tobacco or alcohol use had been elicited, there were 1,360 (27.7%) patients with no history of substance use. The site of the primary was the upper third in 906 (12.8%), middle third esophagus in 2,942 (41.5%), lower third in 2,331 (32.8%) and gastroesophageal junction in 917 (12.9%) patients. The predominant histology was squamous cell carcinoma in 6,413 (81.4%) patients and adenocarcinoma in 1461 (18.6%). There was no change in the histologic pattern over the period of the study; squamous cell carcinoma constituted 78.5% of the cases in 2003, and 85.5% in 2018; Chi square test for the year wise trend in histologic patterns was not significant, p=0.143. Evaluation of the histologic subtype according to sex revealed that in the male patients, there were 3890 (76.4%) squamous and 1202 (23.6%) adenocarcinoma cases, while in female patients, there were 2523 (90.7%) squamous and 259 (9.3%) adenocarcinoma cases. On a uni variate analysis, male sex (p<0.001), a history of tobacco or alcohol use (p<0.001), and the presence of comorbidity (p<0.007) were associated with an increased risk of squamous cell carcinoma. Multivariate analysis by logistic regression model revealed that female sex and use of tobacco or alcohol were positively associated with squamous cell carcinoma, while the presence of comorbities and primary in lower esophagus/GEJ were positively associated with adenocarcinoma. Conclusions: Squamous cell carcinoma continues to be the commonest esophageal cancer histologic subtype in over 80% Indian patients. The mid esophagus is the most common site (42%). There is no evidence of an epidemiological shift or an increase in the occurrence of adenocarcinoma or of lower esophageal/GEJ malignancy over the past two decades.

Tonsillar Squamous Cell Carcinoma

Chronic lymphocytic leukemia (CLL) patients are at an increased risk for developing more aggressive lymphomas via Richter’s transformation and of developing secondary malignancies. Despite the known association for secondary cancers, oropharyngeal cancers occur rarely. We present a case of a woman with a history of CLL who presented to our facility via transfer for impending airway compromise. Her initial workup was consistent with CLL; however, biopsies were taken of the neck mass because of its aggressive nature. She was treated with rituximab with good response. Final pathology showed evidence of CLL and tonsillar squamous cell carcinoma (SCC). Direct laryngoscopy and further biopsies yielded a diagnosis of unresectable oropharyngeal SCC. She was to be treated with chemotherapy and radiation for her SCC while holding treatment for CLL. This case demonstrates a rare and unexpected concurrent diagnosis.

Abstract Background Voriconazole is a common antifungal medication used in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients. In solid organ transplantation, multiple studies have associated the use of voriconazole with the development of squamous cell carcinoma (SCC) post-transplant, but its association with SCC in allo-HSCT patients is unknown. We sought to determine this association. Methods After IRB approval, Mayo Clinic’s transplant database (2007-2012) was accessed and electronic charts of allo-HSCT patients were retrospectively reviewed. Voriconazole exposure was defined as exposure to voriconazole at any time during treatment of primary disease, prior to or following HSCT. Cumulative voriconazole exposure was defined as total days of voriconazole use following HSCT; days were not required to be consecutive. Two time-dependent voriconazole exposure variables were defined: (1) history of voriconazole exposure (yes/no) over time, and (2) cumulative days on voriconazole over time. Results 404 patients underwent allo-HSCT during this timeframe, and 381 patients (table 1) were included in the final analysis. 23 patients were excluded (8 patients received multiple transplants, 9 patients were treated under pediatric protocols, 6 patients lacked research consent). 312/381 received voriconazole; other antifungal therapy included fluconazole (n=40), posaconazole (n=23), anidulafungin (n=1), and caspofungin (n=5). Median duration of cumulative days of voriconazole was 214 (range 2 -1553). SCC developed in 26/312 exposed to voriconazole and in 1/69 who received alternative antifungals. Cumulative incidence of SCC at 1 year was 3%, 2 years was 8%, 3 years was 13%, 4 years was 14%, and at 5 years was 19% (figure 1). Cumulative days of voriconazole use was found to be a risk factor for the development of SCC, and this relationship persisted in a multivariate model using previously identified risk factors (gender, age at transplant, TBI conditioning regimen, skin cancer pre-HSCT, chronic GVHD) as covariates (HR 1.859 for each 180 days of use, p<0.001). History of prior voriconazole exposure was not associated with an increased risk of SCC after covariate adjustment (HR 2.436, p=0.2369). Conclusion This is the first study to establish cumulative days of voriconazole use as a risk factor for SCC development following allo-HSCT, and may help guide appropriate antifungal prophylaxis in this patient population which is already at an increased risk of developing skin cancers.

Summary Patients with head and neck squamous cell carcinoma (HNSCC) have an increased risk of developing esophageal second primary tumors (ESPTs). We aimed to determine the incidence, stage, and outcome of synchronous ESPTs in patients with HNSCC in a Western population. We performed a prospective, observational, and cohort study. Patients diagnosed with HNSCC in the oropharynx, hypopharynx, any other sub-location in combination with alcohol abuse, or patients with two synchronous HNSCCs, between February 2019 and February 2020 underwent screening esophagogastroduodenoscopy (EGD). ESPT was defined as presence of esophageal squamous cell carcinoma (ESCC) or high grade dysplasia (HGD). Eighty-five patients were included. A lesion suspected for ESPT was detected in 14 of 85 patients, which was pathologically confirmed in five patients (1 ESCC and 4 HGD). The radiotherapy field was extended to the esophagus in two of five patients, HGD was treated with endoscopic resection in three of five patients. None of the ESPTs were detected on MRI and/or CT-scan prior to EGD. Of the remaining nine patients, three had low grade dysplasia on histology whereas the other six patients had benign lesions. Incidence of synchronous ESPT was 5.9% in our cohort of HNSCC patients. All ESPTs were diagnosed at an early stage and treated with curative intent. We recommend that screening for synchronous ESPTs should be considered in a selected group of patients with HNSCC.

Background The myeloperoxidase (MPO) -463G>A (rs2333227) polymorphism has been linked with increased susceptibility to the development of various malignancies. However, the data on the association of the MPO -463G>A transition with cervical cancer remain inconsistent. Methods Using high resolution melting analysis we genotyped this polymorphism in women with cervical squamous cell carcinoma (SCC) (n = 476) and controls (n = 493) from a Polish Caucasian population. Logistic regression analysis was used to adjust for the effect of confounders such as age, parity, oral contraceptive use, tobacco smoking, and menopausal status, and revealed that the MPO -463G>A single nucleotide polymorphism (SNP) was associated with an increased risk of SCC. Results The adjusted odds ratio (OR) for patients with the A/A genotype versus G/G genotype was 0.718 (95% CI 0.531-0.972, p = 0.0316). Stratified analyses between the MPO -463G>A polymorphism and SCC risks demonstrated a protective role of the MPO -463G>A SNP in patients with a positive history of parity and negative history of tobacco smoking. In patients with a positive history of parity, the age-adjusted OR for the A/A versus G/G genotype was 0.667 (95% CI 0.479-0.929, p = 0.0164). The age-adjusted OR for patients with a negative history of tobacco smoking for the A/A versus G/G genotype was 0.491 (95% CI 0.313-0.770, p = 0.0019). Conclusions Our study demonstrated that the MPO -463G>A SNP may protect from SCC in women from Polish Caucasian populations.

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.
