  1. Fulltext Triple primary cancers of the larynx, lung and thyroid presenting in one patient
    Iqbal FR, Sani A, Gendeh BS, Aireen I
    Med J Malaysia, 2008 Dec;63(5):417-8.
    PMID: 19803306 MyJurnal
    Patients with multiple malignant primary tumours are often described, based on their chronology of presentation, as simultaneous, synchronous or metachronous tumours. Lung malignancies presenting in association with head and neck tumours are well documented while there have been small series of thyroid synchronous cancers presenting with laryngeal lesions in literature. No cases, to our knowledge, have been reported in literature of a single patient with all three laryngeal, lung and thyroid malignancies. We report one such case of a 71-year-old Chinese man who had undergone a total laryngectomy for a recurrent cancer of the larynx only to be found to have tumours of the lung and thyroid in the post-operative period and he eventually died of post-operative complications. We also discuss screening for lung and thyroid malignancies in patients with head and neck squamous cell carcinoma (SCC).

    Tan SC, Ismail MP, Duski DR, Othman NH, Bhavaraju VM, Ankathil R
    Cancer Invest, 2017 Mar 16;35(3):163-173.
    PMID: 28301252 DOI: 10.1080/07357907.2017.1278767
    This study aimed to identify the most stably expressed reference genes from a panel of 32 candidate genes for normalization of reverse transcription-quantitative real-time polymerase chain reaction data in cancerous and non-cancerous tissues of human uterine cervix. Overall, PUM1, YWHAZ, and RPLP0 were identified as the most stably expressed genes in paired cancerous and non-cancerous tissues. The results were further stratified by the state of malignancy of the tissues, histopathological type of the cancer, and the human papillomavirus-type.

  6. Detection of host-specific immunogenic proteins in the saliva of patients with oral squamous cell carcinoma
    Mu AK, Chan YS, Kang SS, Azman SN, Zain RB, Chai WL, et al.
    J Immunoassay Immunochem, 2014;35(2):183-93.
    PMID: 24295181 DOI: 10.1080/15321819.2013.836535
    The main purpose of this article is to develop a new and reliable saliva-based clinical diagnostic method for the early detection of oral squamous cell carcinoma (OSCC). This study used an immunoproteomic approach which allowed the detection of immunogenic host proteins in patients' samples using pooled human antibodies. In an attempt to investigate potential biomarkers of OSCC, two-dimensional electrophoresis (2-DE) followed by immunoblotting of saliva from patients and controls were compared. The protein spots of interest were analyzed using 2-DE image analyzer and subsequently subjected to MALDI-TOF/TOF and then matched against NCBI database. The result showed that four protein clusters, namely Human Pancreatic Alpha-amylase (HPA), Human Salivary Amylase (sAA), keratin-10 (K-10), and Ga Module Complexed with Human Serum Albumin (GA-HSA), had exhibited immunoreactivity in western blot. The results are suggestive of the potential use of the differentially expressed saliva protein as tumor biomarkers for the detection of OSCC. However, further studies are recommended to validate this finding.

  7. Fulltext Potentially malignant disorders of the oral cavity: current practice and future directions in the clinic and laboratory
    Dionne KR, Warnakulasuriya S, Zain RB, Cheong SC
    Int J Cancer, 2015 Feb 1;136(3):503-15.
    PMID: 24482244 DOI: 10.1002/ijc.28754
    Despite commendable progress in the prevention, detection, and treatment of a wide variety of solid tumor types, oral squamous cell carcinoma (OSCC) remains a significant health burden across the globe. OSCC carcinogenesis involves accumulation of genetic alterations that coincide with the multistep malignant transformation of normal oral epithelium. OSCC is often first diagnosed at late stages of the disease (advanced regional disease and/or metastasis). Delayed diagnosis precludes successful treatment and favorable outcomes. In clinical practice, opportunities exist to identify patients with oral potentially malignant disorders (OPMDs), which precede the development of cancer. This review addresses the current status of laboratory and clinical research on OPMDs, with emphasis on leukoplakia and erythroplakia. OSF is also presented, though there is a paucity of published studies on this disorder. We focus on findings that could translate into earlier diagnosis and more efficacious treatment of those lesions with significant malignant potential. We explore how markers of OPMD malignant transformation might be implemented into current diagnostic practice to help clinicians objectively stratify patients into treatment/follow-up groups according to relative risk. We provide an overview of recently concluded and ongoing OPMD chemoprevention trials. We describe laboratory OPMD models that can be used to not only to reveal the genetic and molecular intricacies of oral cancer but also to develop novel screening methods and therapeutic approaches. Finally, we call for targeted screening programs of at-risk populations in order to facilitate diagnosis and treatment of OPMD and early OSCC.

  9. Carcinosarcoma of the palate: report of a case with a diagnosis of sarcomatoid metastasis by fine needle aspiration cytology
    Jayaram G, Elsayed EM
    Acta Cytol., 2005 Sep-Oct;49(5):520-4.
    PMID: 16334029
    BACKGROUND: Carcinosarcoma (sarcomatoid carcinoma) is a rare tumor with a high predilection for the aerodigestive tract. Cytologic diagnosis of metastatic carcinosarcoma has been reported in very few cases.

    CASE: An 84-year-old woman presented with a 2-cm-diameter, right cervical lymph node that was referred for fine needle aspiration cytology (FNAC). She had received radiotherapy for a palatal squamous cell carcinoma 2 years earlier. The FNAC smears had a sarcomatoid appearance. Repeat fine needle aspiration was performed, with cytologic and immunocytochemical staining. Careful consideration of the cytologic and immunophenotypic features led to an impression of carcinosarcoma. Histologic sections of the palatal biopsy that had been previously diagnosed as squamous cell carcinoma were reviewed, and a final diagnosis of carcinosarcoma was established.

    CONCLUSION: Metastasis of rare lesions, such as carcinosarcoma may be confusing and difficult to diagnose on FNAC, especially when the cytologic sample shows a predominantly sarcomatoid component. The difficulty is compounded when the sarcomatoid component happens to have been overlooked on the initial histologic assessment. With representative cytologic sampling, immunocytochemical staining and review of the histologic material, the correct diagnosis was achieved in this case.

  11. Fulltext Squamous Cell Carcinoma Biomarker Sensing on a Strontium Oxide-Modified Interdigitated Electrode Surface for the Diagnosis of Cervical Cancer
    Wang H, Lakshmipriya T, Chen Y, Gopinath SCB
    Biomed Res Int, 2019;2019:2807123.

    Cervical cancer is a life-threatening complication, appearing as the uncontrolled growth of abnormal cells in the lining of the cervix. Every year, increasing numbers of cervical cancer cases are reported worldwide. Different identification strategies were proposed to detect cervical cancer at the earlier stages using various biomarkers. Squamous cell carcinoma antigen (SCC-Ag) is one of the potential biomarkers for this diagnosis. Nanomaterial-based detection systems were shown to be efficient with different clinical biomarkers. In this study, we have demonstrated strontium oxide-modified interdigitated electrode (IDE) fabrication by the sol-gel method and characterized by scanning electron microscopy and high-power microscopy. Analysis of the bare devices indicated the reproducibility with the fabrication, and further pH scouting on the device revealed that the reliability of the working pH ranges from 3 to 9. The sensing surface was tested to detect SCC-Ag against its specific antibody; the detection limit was found to be 10 pM, and the sensitivity was in the range between 1 and 10 pM as calculated by 3σ. The specificity experiment was carried out using major proteins from human serum, such as albumin and globulin. SCC-Ag was shown to be selectively detected on the strontium oxide-modified IDE surface.

    PMID: 19827871
    We studied women with cervical cancer to determine whether they had had a Pap smear within the 3 years preceding cancer development and their understanding of screening for this cancer. The study had 2 parts; Pathology Data and Survey Data. For pathology data, all cases of cervical cancer diagnosed in 2000-2006 were retrieved from eight hospitals and Pap smear history was obtained from clinical records. For the Survey data; patients who were still undergoing treatment in some of these hospitals and three others were administered structured questionnaires to determine their awareness about screening. The results showed 1431 cases of cervical cancer in women aged 25-85 were diagnosed in these hospitals. Most had not had a Pap smear within 3 years before cancer development. The percentages of patients who had had Pap smear ranged from 0-12%. Questionnaires were returned by 221 patients; 56.3% had none or only primary education and 61.1% had a household income of RM 1,000 or less. Level of education and the household income were strongly associated (p<0.05) with knowledge and having had a Pap test. The main reasons cited for not having had a Pap smear were "Never heard about it" (36.2%), "Shy" (10.4%), "Afraid to do it" (13.1%), "Think the test is not important" (8.1%) and "No encouragement from family" (4.5%). A large majority (95.9%) of the patients did not know the optimal interval. In conclusion, a large number of cervical cancer patients had not had a Pap smear within 3 years preceding cancer development and most had inadequate knowledge about this screening test.

  13. p40 in metastatic pulmonary trophoblastic tumour: potential diagnostic pitfall on histopathology
    Vallonthaiel AG, Walia R, Pramanik R, Sharma MC, Jain D
    Malays J Pathol, 2017 Aug;39(2):175-179.
    PMID: 28866701
    p40, one of the two isomers of p63, is nowadays widely used for diagnosis of squamous cell carcinoma, especially in subtyping non-small cell carcinoma on lung biopsies. We describe a case in which lung tumour was misdiagnosed as squamous cell carcinoma due to p40 immunopositivity. A 36-year-old lady presented with cough and left sided chest pain of 2 months duration. Chest imaging revealed a lesion in left lower lobe of the lung and biopsy was suggestive of squamous cell carcinoma. However, past history revealed amputation of great toe for non-healing discharging ulcer which on histopathology was diagnosed as choriocarcinoma. She also had a history of hysterectomy five years ago, details of which were not available. Post-amputation β-hCG levels were high and she had been treated with multimodality chemotherapy for choriocarcinoma. She had good response to chemotherapy initially, however became resistant later on. Review of the lung biopsy in the light of the past history along with extensive literature review led to the final diagnosis of metastatic trophoblastic tumour to lung. Hence, awareness that p40 immunopositivity can be seen in trophoblastic tumours is essential to avoid misdiagnosis, especially in sites like the lung where squamous cell carcinoma is common.

  14. Unusual form of superficial spreading microinvasive squamous cell carcinoma of uterine cervix involving the endometrium of uterus
    Tan GC, Isa MR, Ng SP, Jamil YM
    J Obstet Gynaecol Res, 2004 Oct;30(5):363-7.
    PMID: 15327449
    Microinvasive squamous cell carcinoma of the uterine cervix is a recognized entity and is defined as carcinoma with invasion of less than 5 mm penetration of the stroma and seldom metastasized. Our patient was a 70-year-old, multiparous woman who had a microinvasive, cervical, squamous cell carcinoma. The tumor had spread superficially into the entire endometrial cavity up to the fundus, totally replacing the columnar epithelium. This is an extremely rare phenomenon, with fewer than 20 cases reported so far in the literature.

  16. Cystic lesion of the parotid gland with squamous metaplasia mistaken for squamous cell carcinoma. A case report
    Jayaram G, Pathmanathan R, Khanijow V
    Acta Cytol., 1998 Nov-Dec;42(6):1468-72.
    PMID: 9850664
    BACKGROUND: The diverse range of diseases that affect the salivary glands may lead to problems and pitfalls in cyto-diagnosis. While false negative diagnosis of cystic salivary gland tumors is well known, false positive cytodiagnosis in nonneoplastic salivary cysts is less well documented.

    CASE: An 85-year-old female presented with a painless left parotid gland swelling of three months' duration. Fine needle aspiration cytology yielded fluid, smears of which showed keratinizing squamous cells with nuclear atypia leading to a cytologic diagnosis of cystic squamous cell carcinoma. A total radical parotidectomy followed. Histopathologic study showed cystic dilatation of many of the salivary ducts, which were lined with metaplastic squamous epithelium that showed atypia. There was no evidence of squamous cell carcinoma.

    CONCLUSION: Squamous metaplasia is known to occur in benign salivary gland lesions, such as pleomorphic adenoma and Warthin's tumors, as well as in salivary duct cysts and necrotizing sialometaplasia. However, atypical squamous metaplasia of salivary duct cysts mimicking squamous cell carcinoma on cytology is unusual.

  17. Fulltext Metastatic cervical carcinoma presenting as psoas abscess and osteoblastic and lytic bony metastases
    George J, Lai FM
    Singapore Med J, 1995 Apr;36(2):224-7.
    PMID: 7676275
    A 60-year-old Chinese lady presented with a left flank mass and weight loss. Plain films showed a sclerotic L1 vertebral body, osteopenic L2 and L3 vertebral bodies and loss of left psoas outline. However initially unrevealed history of previous carcinoma of the cervix caused confusion as to the aetiology of a sclerotic vertebral body associated with an left flank collection. Psoas abscess with adjacent bony osteomyelitis was initially suspected. The left flank mass turned out to be an infected necrotic large metastatic lymph node compressing the lower pole of the left kidney. The sclerotic and osteopenic vertebral bodies represented an unusual presentation of bony cervical carcinoma metastases.

  19. Squamous cell carcinoma antigen as an adjunct tumour marker in primary carcinoma of the lung
    Cheah PL, Liam CK, Yap SF, Looi LM
    J Clin Pathol, 1994 Jun;47(6):535-7.
    PMID: 8063936
    AIMS: To determine (1) the detection rate of primary carcinoma of the lung by serological assay of CEA (carcinoembryonic antigen); and (2) whether addition of seroassay of squamous cell carcinoma related antigen before treatment improves detection sensitivity.

    METHODS: A prospective study spanning 27 months was conducted at the University Hospital, Kuala Lumpur. Serum CEA (Abbott IMx) and serum squamous cell carcinoma antigen (Abbott IMx) from patients clinically suspected of having primary carcinoma of the lung, were assayed using the microparticle enzyme immunoassay method.

    RESULTS: Thirty seven cases of histologically confirmed primary lung carcinoma were studied. Of these, 17 were squamous cell carcinomas, 10 adenocarcinomas, nine small cell carcinomas, and one large cell carcinoma. The patients' ages ranged from 34-82 years. The male:female ratio was 3.6:1. Squamous cell carcinoma antigen was raised above the cutoff value of 1.5 ng/ml in 94.1% of squamous cell carcinomas, 20.0% of adenocarcinomas, and 11.1% of small cell carcinomas. By comparison, CEA was raised above the cutoff value of 3.0 ng/ml in 70.6% of squamous cell carcinomas, 77.8% of small cell carcinomas, and 100% of adenocarcinomas. CEA and squamous cell carcinoma antigen were not raised in the patient with large cell carcinoma and in 14 healthy volunteers. None of 15 patients with a variety of benign lung diseases showed a rise of CEA, while two patients--a 25 year old Indian woman with pneumonia and a 64 year old Malay man with bronchial asthma--had raised squamous cell carcinoma antigen values above the cutoff. Serum CEA and squamous cell carcinoma antigen values did not seem to correlate with stage or degree of differentiation of the tumours.

    CONCLUSIONS: The findings suggest that CEA is a good general marker for carcinoma, particularly adenocarcinoma. In contrast, squamous cell carcinoma antigen is more specific for squamous carcinoma.

  20. Fulltext The importance of considering sebaceous gland carcinoma in presumed chalazia in South Asian patients?
    Sagili S, Malhotra R
    Br J Gen Pract, 2013 Feb;63(607):74.
    PMID: 23700655
    A 51-year-old Malaysian female was referred with a left lower eyelid lesion noticed 4 years ago. She consulted her GP a year ago and was diagnosed to have a chalazion. Her GP requested funding for treatment. The primary care trust (PCT) considered this a low-priority procedure and declined funding. One year later she approached her GP again and was referred to a hospital for management of this eyelid lesion (Figure 1). She underwent a biopsy and the histology was suspicious of a squamous cell carcinoma. She was referred to our unit. On examination, she had a left lower eyelid, firm 4mm nodule with thickening and distortion of tarsal conjunctiva. With a clinical suspicion of sebaceous gland carcinoma (SGC), a wedge excision of the lesion was performed. Paraffin section histology confirmed complete excision of SGC. Delayed repair required a Tenzel flap. She remains asymptomatic at 5-month follow-up.
