Wu N, Li Y, Ma X, Huang Z, Chen Z, Chen W, Zhang R. High incidence of HPV infection in minors with oral squamous cell carcinoma. Diagn Pathol 2024; 19:51. [PMID: 38461286 PMCID: PMC10925008 DOI: 10.1186/s13000-024-01470-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 02/19/2024] [Indexed: 03/11/2024] Open
Abstract
BACKGROUND Oral squamous cell carcinoma in minors is considered to be a distinct entity from OSCC in older patients, with an uncertain etiology. Human papillomavirus (HPV) infection may trigger the initiation and promote the progression of OSCC, but these roles have not been firmly established.We aimed to explore the correlation between HPV infection and the development of oral squamous cell carcinoma in minors and know the characteristics of OSCC in young patients more thoroughly. METHOD From January 2013 to December 2022,6 cases of OSCC aged < 15 years were selected from the Department of Oral Pathology, Peking University School of Stomatology, Beijing, China. All cases underwent testing for high-risk HPV mRNA infection using the RNA scope technique, and immunohistochemical staining was performed to investigate the expression of p16, pan-cytokeratin (CK), CK5/6, CK7, CK8/18, epidermal growth factor receptor (EGFR), p53, and Ki-67. Furthermore, we reviewed the literature on OSCC in patients aged < 21 years. CONCLUSIONS Minors OSCC is associated with HPV infection, and that p16 can serve as an immunohistochemical marker of HPV positivity.

Oral cancer and oral potentially malignant disorders in patients with Fanconi anemia - A systematic review. Oral Oncol 2024; 150:106699. [PMID: 38309198 DOI: 10.1016/j.oraloncology.2024.106699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 01/10/2024] [Accepted: 01/18/2024] [Indexed: 02/05/2024]
Abstract
The purpose of the present study was to perform a systematic review focusing on oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD) in Fanconi anemia (FA) individuals. Electronic searches were undertaken in five databases supplemented by manual scrutiny and gray literature. Case reports and/or cases series were included. The searches yielded 55 studies describing 112 cases of OSCC (n = 107) and/or OPMD (n = 5) in FA individuals. The mean age at diagnosis of OSCC/OPMD was 27.1 (±9.6) years, and females (51.8 %) were slightly more affected. Ulcer (n = 37) or mass (n = 25) were described as clinical presentations for OSCC and OPMD. White lesions (n = 4) were the most common manifestation in OPMD. Tongue (47.2 %) was the most frequent location. Sixty-one (54.5 %) individuals underwent HSCT. Surgical resection (n = 75) was the main treatment adopted. The estimated rate of OPMD malignant transformation was 1.8 % and recurrences following OSCC excision occurred in 26.8 % of individuals. Overall, at 60 months of follow-up, the probability of survival fell to 25.5 % and at 64 months the probability of recurrence increased to 63.2 %. The present data support the need for strict surveillance of patients with FA, even in the absence of OPMD, for early OSCC detection and reduction of mortality.

[PMID: 36497256 PMCID: PMC9737965 DOI: 10.3390/cancers14235775] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 11/09/2022] [Accepted: 11/21/2022] [Indexed: 11/25/2022] Open
Abstract
After haematopoietic stem cell transplantation and a history of GVHD, the risk of developing secondary malignancies, including oral cancer, is higher. This risk increases with time post-transplantation; therefore, pediatric patients undergoing HSCT, who have long-term survival chances, are in a high-risk category. The aim of this review is to provide data on HSCT, GVHD, clinical manifestations, histological features and treatment of oral cancer, and outcomes in HSCT pediatric patients, affected by oral GVHD, who have been developed OSCC. Descriptive statistics were used to validate data. Fifteen studies on a total of 33 patients were selected. Data on oral cancer showed that the tongue was the most frequently involved site (13 pts; 39.39%), followed by the floor of the mouth (4 pts; 12.12%), and buccal mucosa (4 pts; 12.12%). Oral squamous cell carcinoma was the histological feature reported. There were 19 (57.58%) deaths occurring between 2 and 46.5 months after OC diagnosis. Eleven patients survived with a median follow-up of 34 months. Considering the high risk of developing oral cancer, a conventional oral examination every 6 months is recommended for HSCT pediatric patients who have developed GVHD.

Abstract
Fanconi anemia, the most frequent genetic cause of bone marrow failure, is characterized by an extreme predilection toward multiple malignancies, including a greater than 500-fold incidence of head and neck squamous cell carcinoma (HNSCC) relative to the general population. Fanconi anemia-associated HNSCC and esophageal SCC (FA-HNSCC) often present at advanced stages with poor survival. Surgical resection remains the primary treatment for FA-HNSCC, and there is often great reluctance to administer systemic agents and/or radiotherapy to these patients given their susceptibility to DNA damage. The paucity of FA-HNSCC case reports limits evidence-based management, and such cases have not been analyzed collectively in detail. We present a systematic review of FA-HNSCC treatments reported from 1966 to 2020, defining a cohort of 119 patients with FA-HNSCC including 16 esophageal SCCs (131 total primary tumors), who were treated with surgery, radiotherapy, systemic therapy (including cytotoxic agents, EGFR inhibitors, or immune checkpoint inhibitors), or a combination of modalities. We summarize the clinical responses and regimen-associated toxicities by treatment modality. The collective evidence suggests that when possible, surgical resection with curative intent should remain the primary treatment modality for FA-HNSCC. Radiation can be administered with acceptable toxicity in the majority of cases, including patients who have undergone stem cell transplantation. Although there is little justification for cytotoxic chemotherapy, EGFR inhibitors and tyrosine kinase inhibitors may be both safe and effective. Immunotherapy may also be considered. Most oncologists have little personal experience with FA-HNSCC. This review is intended as a comprehensive resource for clinicians.

Abstract
Purpose Fanconi anemia (FA) is a rare genetic disorder characterized by congenital anomalies, progressive bone marrow failure and high susceptibility to solid tumors, especially head and neck squamous cell carcinoma (HNSCC). Management of FA patients with head and neck cancer is a challenge due to increased risk of surgery, poor tolerance of chemotherapy, and severe myelotoxicity of radiotherapy. Patients and Methods We present a case of a 33-year-old man with carcinoma of oral tongue (T1N2M0), who experienced prolonged and profound bone marrow failure as a consequence of concurrent cisplatin/radiation. The young patient who developed HNSCC without risk factors, the myelotoxicity after exposure to platinum-based agent cisplatin and the further evaluation of phenotypic characteristics raised suspicion of FA. Whole exome sequencing performed for the patient and parents ultimately established the diagnosis of FA. Results Genetic testing in 23 FANC genes revealed two novel heterozygous mutations, c.367C>T and c.3971_3972delCGinsTT in FANCA gene of the patient, which were inherited from his father and mother, respectively. Radiotherapy with reduced dose has successfully alleviated the symptoms of tumor invasion and progression, and the radiation-related side effects were acceptable. Unfortunately, the patient eventually died of locoregional disease progression. Conclusion This case highlights the importance of considering the diagnosis of FA in young patients who develop HNSCC in the absence of risk factors, thus permitting more effective oncological treatment strategies and improved outcomes. In conclusion, any decision on different modalities of management in such patients should be based on a balance between locoregional control and therapeutic toxicity.

Abstract
PURPOSE The purpose of this study was to describe 3 cases of tongue cancer in patients less than 21 years of age. Secondarily, a literature review was performed to examine disease presentation, risk factors, prognosis, and treatment strategies for young persons with tongue cancer. METHODS The authors presented 3 cases of childhood tongue cancer between 2009 and 2020 at the University of Michigan Department of Oral and Maxillofacial Surgery (Ann Arbor, MI). An electronic literature review was conducted via PubMed, Embase, Web of Science, and MLibrary. RESULTS Including the present case series, 64 studies reporting 108 cases were identified. Age at presentation ranged from newborn to 20 years, with a mean age of 14.5 years. The majority of patients were female (52.2%); 68.1% of patients presented with T1 or T2 disease. Nodal metastases were seen in 56.1% of patients. The most commonly identified predisposing factors included Fanconi anemia (13.9%), bone marrow transplant (9.3%), tobacco use (6.5%), and xeroderma pigmentosum (4.6%). Most patients received surgery alone (37.5%), followed by surgery with adjuvant radiation (33.8%); 60.6% underwent neck dissection. Overall survival was 60.3% at 1 year and 43.6% at 5 years. CONCLUSIONS Oral tongue cancer in the young is a rare disease with poorly understood etiology. There is a need for oncologists and maxillofacial surgeons to collaborate in the study of genetic, social, environmental, and medical risk factors contributing to the disease. All patients should undergo high-throughput genetic sequencing to expand our understanding of the disease process and allow for targeted treatment strategies.

Abstract
Fanconi Anemia is a recessive and rare genetic disorder, characterized by chromosomal instability that induces congenital alterations in individuals. Aplastic anemia due to the progressive failure of the bone marrow, malignant neoplasias such as acute myeloid leukemia, liver tumors and squamous cell carcinoma are some of the possible evolutions of Fanconi Anemia. Some of these diseases develop mainly after bone marrow transplantation. The aim of this critical review of the literature was to discourse about the main oral manifestations and their involvement in the health of individuals who are ill with Fanconi Anemia. The clinical oral findings described in the literature include periodontal changes, such as gingivitis and aggressive periodontitis, recurrent aphthous ulcers and traumatic lesions. Papillary atrophy, macroglossia, melanic pigmentation and squamous cell carcinoma are the most common oral manifestations on the tongue. An increased risk for the development of malignant neoplasias in individuals with Fanconi Anemia has been reported, and this is progressive after bone marrow transplantation. In radiographs, dental anomalies such as the presence of supernumerary teeth, tooth agenesis, tooth rotation and transposition of teeth are observed. Salivary flow and some salivary components are also altered. Due to the increased susceptibility to the development of cancer in this specific population, it is important for the dentist to know the common oral manifestations and potentially cancerous lesions, in order to make an early diagnosis in individuals with Fanconi Anemia.

Abstract
Cancer of the oral cavity accounts for approximately 3% of all malignancies diagnosed annually in 270,000 patients world-wide. Oral cancer is the 12th most common cancer in women and the 6th in men. Many oral squamous cell carcinomas develop from potentially malignant disorders (PMDs). Lack of awareness about the signs and symptoms of oralPMDs in the general population and even healthcare providers is believed to be responsible for the diagnostic delay of these entities. The aim of this article is to update and improve the knowledge of healthcare providers about oral PMDs.

Abstract
Patients with the rare genetic disease, Fanconi anemia (FA), are highly susceptible to squamous cell carcinomas arising at multiple anatomic sites including the head and neck region. Human papillomaviruses (HPVs), particularly HPV16, are associated with ∼20% of head and neck squamous cell carcinomas (HNSCCs) in the general population. Some but not other investigators have reported that HNSCCs in FA patients are much more frequently positive for HPV. In addition, studies have demonstrated an interaction between the HPV16 E7 oncoprotein and the FA pathway, a DNA damage response pathway deficient in FA patients. On the basis of these studies, it was hypothesized that the FA pathway contributes to repair of DNA damage induced by HPV16 E7, providing one explanation for why FA patients are predisposed to HPV-associated HNSCCs. To determine the importance of the FA pathway in modulating the oncogenic abilities of E7, we crossed K14E7 transgenic (K14E7) and fancD2 knockout mice (FancD2(-/-)) to establish K14E7/FancD2(-/-) and K14E7/FancD2(+/+) mice and monitored their susceptibility to HNSCC when treated with a chemical carcinogen. K14E7/FancD2(-/-) mice had a significantly higher incidence of HNSCC compared with K14E7/FancD2(+/+) mice. This difference correlated with an increased proliferative index and the increase in expression of biomarkers that are used to assess levels of DNA damage. These animal studies support the hypotheses that FA patients have increased susceptibility to HPV-associated cancer and that the FA DNA damage response pathway normally attenuates the oncogenic potential of HPV16 E7.
