Increased Risk

Bladder exstrophy is a complex abnormality and is traditionally treated within the early years of life. It is associated with an increased risk of bladder cancer, with 95% of the arising tumors being adenocarcinomas and 3 to 5% being squamous cell carcinomas. HPV infections are also associated with an increased risk of bladder cancer. This case represents a patient with bladder exstrophy that gave rise to coinciding squamous cell carcinoma and adenocarcinoma. Final pathology results showed an infection with HPV. We presented the management of the case and discussed the diagnosis and treatment methods for this patient.

Immunohistochemical Analyses

Abstract Purpose Squamous cell carcinomas and adenocarcinomas are the most common types of cervical cancer. Compared to squamous cell carcinomas, adenocarcinomas are more common in younger women and have a poorer prognosis. Yet, so far, no useful biomarkers have been developed for these two types of cancer. In the following study, we examined the combination of cytokeratin 5/6, P63, P40 and MUC5AC for distinguishing squamous cell carcinoma (SCC) from adenocarcinoma of the cervix (AEC). Materials and Methods A total of 101 SCC and 108 AEC were collected. Immunohistochemical analyses were conducted to determine the expression of CK5/6, P63, P40, CK7 and MUC5AC. One pathologist who was blinded to the patient’s clinical and pathological data interpreted the staining results. Results MUC5AC and CK7 were detected in 81.48% and 82.41% of AEC cases compared to 9.9% and 49.50% of SCC cases (P < 0.05); the specificity of MUC5AC was higher than that of CK7 in AEC (P < 0.05). The sensitivity of MUC5AC combined with P40 or P63 was similar to that of CK7, but the specificity was slightly higher than that of CK7 in AEC. Moreover, the expression of MUC5AC was correlated with the degree of tumor differentiation in adenocarcinomas (P = 0.036) and was not related to the prognosis of cervical adenocarcinoma and subtypes. Conclusions MUC5AC may be useful as a biomarker for differential diagnoses between squamous carcinoma and adenocarcinoma of the cervix.

Tissue Samples

In this article, we investigated prevalence and distributed types of human papillomavirus (HPV) among female cervical squamous cell carcinoma patients in eastern China (mainly in Jiangsu Province). Tissue samples of total 1021 cases with cervical squamous cell carcinoma were incurred from female patients passing through biopsy or surgery. HPV DNA and genotypes of all subjects were examined using polymerase chain reaction (PCR) and gene-chip. There were 937 positive cases among 1021 cervical squamous cell carcinoma tissue samples with the total HPV infection rate of 91.77%. The HPV infection rate of single type was 75.42%. The predominant types of single infection with HPV were HPV 16 (52.60%), HPV 18 (5.19%), HPV 58 (4.51%), HPV 52 (2.84%), HPV 31 (2.74%), HPV 33 (2.45%), HPV 59 (1.76%) and HPV 45 (0.88%). The HPV infection rate of multiple types was 16.35%. The predominant types of multiple infection with HPV were HPV 16+18 (19.16%), 16+58 (6.59%),16+52 (5.99%), 16+33 (5.39%), 11+16 (2.99%), 16+31 (2.99%), 16+45 (2.99%), 16+42 (2.40%) and 16+59 (2.40%). Cervical squamous cell carcinomas had a close relationship with HPV infection. HPV 16, 18, 58, 52, 31, 33, 59, 45 with high prevalence in the cervical squamous cell carcinoma deserve great attention in eastern China (mainly in Jiangsu Province). The protection spectrum of divalent vaccine and ninevalent vaccine were, respectively, 68.52% (642/937) and 90.82% (851/937) in the cases of cervical squamous cell carcinomas.

A large proportion of vaginal and vulvar squamous cell carcinomas (SCCs) and intraepithelial neoplasias (VAIN and VIN) are associated with HPV infection, mainly type 16. The purpose of this study was to identify HPV genotypes, as well as E6/E7 mRNA expression of high-risk HPVs (16, 18, 31, 33, and 45) in 56 histology samples of VAIN, VIN, vaginal, and vulvar SCCs. HPV was identified in 56% of VAIN and 50% of vaginal SCCs, 71.4% of VIN and 50% of vulvar SCCs. E6/E7 mRNA expression was found in one-third of VAIN and in all vaginal SCCs, 42.9% of VIN and 83.3% of vulvar SCCs. Our data indicated that HPV 16 was the commonest genotype identified in VAIN and VIN and the only genotype found in SCCs of the vagina and vulva. These findings may suggest, in accordance with other studies, that mRNA assay might be useful in triaging lesions with increased risk of progression to cancer.

SUMMARYThe oncogenic potential of human papillomaviruses (HPV) is well known in the context of cervical carcinoma; however, their role in the development of oesophageal squamous cell carcinoma (OSCC) is less clear. We aimed to determine the extent of the association between HPV infection and OSCC. A comprehensive literature search found 132 studies addressing HPV and OSCC in human cases, and a meta-analysis was performed using a random-effects model. There was evidence of an increased risk of OSCC in patients with HPV infection [odds ratio (OR) 2·69, 95% confidence interval (CI) 2·05–3·54]. The prevalence of HPV in OSCC was found to be 24·8%. There was an increased risk associated with HPV-16 infection (OR 2·35, 95% CI 1·73–3·19). Subgroup analyses showed geographical variance, with Asia (OR 2·94, 95% CI 2·16–4·00), and particularly China (OR 2·85, 95% CI 2·05–3·96) being high-risk areas. Our results confirm an increase in HPV infection in OSCC cases.

Abstract Background Bladder tumors in pregnancy are extremely rare. No more than 50 cases have been published to date, including all histologic variants, and only three cases of bladder squamous cell carcinoma have been described. Case presentation We present a clinical case of a 31-year-old woman with bladder squamous cell carcinoma in the second trimester of pregnancy. After a C-section at 30 weeks, we performed radical cystectomy with extended bilateral lymphadenectomy, hysterectomy and right oophorectomy. The Studer neobladder technique was performed for urinary tract reconstruction. Definitive pathology showed invasive bladder squamous cell carcinoma, Grade 2, with microscopic infiltration of the perivesical fat, negative margins, and 3/28 lymph nodes with carcinoma (pT3aN2M0). The patient underwent 18 months of surveillance after radical cystectomy, without recurrence by PET-CT. Conclusions Bladder cancer in pregnant women is extremely rare but must be considered in those with recurrent gross hematuria and/or recurrent urinary tract infection. To our knowledge, this case involves the longest recurrence-free survival of a pregnant woman with squamous cell bladder cancer published thus far.

Genetic Landscape

Squamous cell carcinomas of the lung, head and neck, esophagus, and cervix account for more than two million cases of cancer per year worldwide with very few targetable therapies available and minimal clinical improvement in the past three decades. Although these carcinomas are differentiated anatomically, their genetic landscape shares numerous common genetic alterations. Amplification of the third chromosome’s distal portion (3q) is a distinguishing genetic alteration in most of these carcinomas and leads to copy-number gain and amplification of numerous oncogenic proteins. This area of the chromosome harbors known oncogenes involved in squamous cell fate decisions and differentiation, including TP63, SOX2, ECT2, and PIK3CA. Furthermore, novel targetable oncogenic kinases within this amplicon include PRKCI, PAK2, MAP3K13, and TNIK. TCGA analysis of these genes identified amplification in more than 20% of clinical squamous cell carcinoma samples, correlating with a significant decrease in overall patient survival. Alteration of these genes frequently co-occurs and is dependent on 3q-chromosome amplification. The dependency of cancer cells on these amplified kinases provides a route toward personalized medicine in squamous cell carcinoma patients through development of small-molecules targeting these kinases.
