Bilateral Ovarian Clear Cell Carcinoma Arising in 17 Year Longstanding History of Bilateral Ovarian Endometriosis

Win TT, Nik Mahmood NMZ, Ma SO, Ismail M

Iran J Pathol, 2016;11(5):478-482.

Clear cell carcinoma of ovary is uncommon ovarian tumour that arises from surface epithelium of ovary. It has well-known association with ovarian endometriosis. We report here the first case of bilateral clear cell carcinoma of ovaries in a 40-year-old woman with a 17-year history of bilateral ovarian endometriosis. In addition, during the longstanding duration of the endometriosis, the patient was treated with hormonal therapy, including oestrogen. It represents the first report of such bilateral involvement in the background of ovarian endometriosis. This should prompt clinicians to be aware that prolonged hormonal treatment of endometriosis may precipitate bilateral malignancy of the ovary.

PMID: 31857764 DOI: 10.1007/s13193-019-00977-8

We report a unique case of differentiated thyroid carcinoma (DTC) with squamous metaplasia complicated with chronic discharging ulcer. A 76-year-old gentleman was referred to us after defaulted treatment 1 year post-total thyroidectomy. He presented to us with long-standing chronic, non-healing, ulcerative and discharging wound at the anterior neck at previous total thyroidectomy scar. The primary tumour was histologically diagnosed as papillary malignant cells with extensive squamous metaplasia. Squamous metaplasia is a rare finding in thyroid carcinoma that carried a poorer prognostic factor.

Fulltext Airway emergency from spontaneous haemorrhagic thyroid cancer

Vijendren A, Ladha N, Hilger AW

Med J Malaysia, 2014 Aug;69(4):187-8.

PMID: 25500848

Spontaneous thyroid haemorrhages are rare. There are reported cases occurring in thyroid nodules and cysts but none in thyroid malignancies. We describe a 48 year old who presented to the on-call ENT team with a rapidly progressing neck swelling that was interfering with his airway. After resuscitation, the patient underwent a right lobectomy to stop the bleeding. Histology showed a thyroid follicular carcinoma. As per the regional multidisciplinary team discussion, he underwent a completion thyroidectomy followed by radioactive iodine treatment. We conclude that spontaneous haemorrhages of the thyroid gland can occur in malignancies and stress the importance of early histological diagnosis.

Bladder Adenocarcinoma: A Persisting Diagnostic Dilemma

Vasudevan G, Bishnu A, Singh BMK, Nayak DM, Jain P

J Clin Diagn Res, 2017 Mar;11(3):ER01-ER04.

PMID: 28511402 DOI: 10.7860/JCDR/2017/24590.9536

Primary urinary Bladder Adenocarcinoma (PBA) is an uncommon neoplasm and can cause diagnostic difficulties due to histologic similarities with adenocarcinomas of adjacent structures like Gastrointestinal Tract (GIT) and prostate, since involvement of the bladder by metastasis or direct spread can occur. Seven cases of bladder adenocarcinomas were diagnosed during a period of four years in a tertiary care hospital. Patient's age ranged from 26-78 years with a male predilection. Three cases were signet ring type adenocarcinomas, two cases were subtyped as enteric variant, one as mucinous variant and one as adenocarcinoma Not Otherwise Specified (NOS) variant. One case showed urachal involvement. Common site of involvement was the base and posterior wall of the bladder. Three cases had prior history of GIT malignancy. No morphologic difference was identified to differentiate primary from secondary adenocarcinomas. Bladder adenocarcinoma is rare tumours. Primary and secondary adenocarcinomas cannot be distinguished from each other on morphologic grounds. Ancillary studies may have limited role in distinguishing between the two. Hence, clinical correlation has a major role in their evaluation.

Fulltext Distinctive Clinico-Pathological Characteristics of Colorectal Cancer in Sabahan Indigenous Populations

Valan A, Najid F, Chandran P, Abd Rahim AB, Chuah JA, Roslani AC

Asian Pac J Cancer Prev, 2021 Mar 01;22(3):749-755.

PMID: 33773538 DOI: 10.31557/APJCP.2021.22.3.749

BACKGROUND: Malaysia is an ethnically diverse nation, comprising Malay, Chinese, Indian and indigenous groups. However, epidemiological studies on colorectal cancer have mainly focused on the three main ethnic groups. There is evidence that the clinico-pathological characteristics of some cancers may differ in indigenous populations, namely that they occur earlier and behave more aggressively. We aimed to determine if there were similar differences in colorectal cancer, focusing on the indigenous populations of Sabah.

METHODS: Histopathological reports of all patients diagnosed with colorectal carcinoma from January 2012 to December 2016 from public hospitals in Sabah were retrieved from the central computerized database of the Pathology Department of Queen Elizabeth Hospital in Kota Kinabalu, Sabah. Supplementary data was obtained from patients' case files from each hospital. Clinico-pathological data were analysed using the IBM SPSS Statistical Software Version 23 for Windows for descriptive statistics (mean, median, ASR, AR, relative risk) and inferential statistics (Chi square test).

RESULTS: A total of 696 patients met the inclusion criteria. The median age for colorectal cancer in Sabah was 62 years (95% CI 60.3 to 62.3), with an age specific incidence rate of 21.4 per 100 000 population. The age specific incidence rate in the indigenous populations was 26.6 per 100 000, much lower than the Chinese, at 65.0 per 100 000. The risk of colorectal cancer occurring before the age of 50 was three times higher in the indigenous population compared to the Chinese. The tumours were mainly left-sided (56.5%), adenocarcinoma in histology (98.4%) and moderately differentiated (88.7%). Approximately 79.2% of patients received curative treatment.

CONCLUSION: Indigenous populations in Sabah develop colorectal cancer at an earlier age, and present at more advanced stages. This has implications for screening and therapeutic strategic planning.

MyJurnal

We report a case of a 37-year-old smoker who presented with painless and sudden onset of loss of upper field vision of the right eye, associated with one month history of dry cough which was unresponsive to antibiotic and subsequent anti- tuberculosis therapy. Visual acuity at presentation was counting finger. There was bullous retinal detachment on examination. Radiological imaging revealed multiple lung opacities, involving the brain and the right orbit. Bronchoscopy and biopsy confirmed the diagnosis of adenocarcinoma of the lung. This case illustrates masquerade syndrome of which a lung carcinoma harbours behind a seemingly innocent retinal detachment. It also highlights the importance of entertaining lung carcinoma as a differential diagnosis in suspected tuberculosis among heavy smokers.

Fulltext Anomalous pancreatico-biliary junction--a non-dilated biliary system and gallbladder carcinoma

Toufeeq Khan TF, Hayat FZ, Muniandy S

Singapore Med J, 1998 Jan;39(1):25-6.

PMID: 9557100

Anomalous pancreatico-biliary junction (APBJ) is commonly associated with cystic dilatation of the bile ducts but recently, several cases without the cystic dilatation have been reported. We treated a young female patient with intractable back and epigastric pain of three months duration. The spine was normal on magnetic resonance imaging (MRI), but several lymph nodes were seen around the coeliac axis. An APBJ, a non-cystic biliary system, non-filling of the gallbladder and an irregular right margin of the bile duct were evident on endoscopic retrograde pancreatography (ERCP), which was highly suggestive of gallbladder (GB) malignancy. At surgery, the GB was hard with local infiltration of the bile duct. Numerous large para-aortic and supraduodenal lymph nodes were present and only a biopsy was possible. Details of the case are presented and the growing etiological importance of an APBJ, especially without cystic biliary dilatation in gallbladder carcinogenesis is discussed.

Fulltext Expression of Galectin-3 and Galectin-7 in thyroid malignancy as potential diagnostic indicators

Than TH, Swethadri GK, Wong J, Ahmad T, Jamil D, Maganlal RK, et al.

Singapore Med J, 2008 Apr;49(4):333-8.

PMID: 18418527

It has been suggested that Galectin-3 (Gal-3) and Galectin-7 (Gal-7) are potential tumour markers for differentiating thyroid carcinoma from its benign counter part. Galectins are beta-galactoside-binding proteins with Gal-3 being a redundant pre-mRNA splicing factor. They are supposed to be p53-related regulators in cell growth and apoptosis, being either anti-apoptotic or pro-apoptotic. Although the value of Gal-3 has been studied extensively, there is little knowledge regarding the expression of Gal-7 in thyroid malignancy.

PMID: 24369485 DOI: 10.1155/2013/958407

Gynura bicolor (Compositae) which is widely used by the locals as natural remedies in folk medicine has limited scientific studies to ensure its efficacy and nontoxicity. The current study reports the total phenolic content, antioxidant capacity, cytotoxicity, and acute oral toxicity of crude methanol and its fractionated extracts (hexane, ethyl acetate, and water) of G. bicolor leaves. Five human colon cancer cell lines (HT-29, HCT-15, SW480, Caco-2, and HCT 116), one human breast adenocarcinoma cell line (MCF7), and one human normal colon cell line (CCD-18Co) were used to evaluate the cytotoxicity of G. bicolor. The present findings had clearly demonstrated that ethyl acetate extract of G. bicolor with the highest total phenolic content among the extracts showed the strongest antioxidant activity (DPPH radical scavenging assay and metal chelating assay), possessed cytotoxicity, and induced apoptotic and necrotic cell death, especially towards the HCT 116 and HCT-15 colon cancer cells. The acute oral toxicity study indicated that methanol extract of G. bicolor has negligible level of toxicity when administered orally and has been regarded as safe in experimental rats. The findings of the current study clearly established the chemoprevention potential of G. bicolor and thus provide scientific validation on the therapeutic claims of G. bicolor.

Fulltext Review of risk factors associated with the anastomosis leakage in anterior resection in Hospital Universiti Kebangsaan Malaysia

Teoh CM, Gunasegaram T, Chan KY, Sukumar N, Sagap I

Med J Malaysia, 2005 Aug;60(3):275-80.

PMID: 16379179 MyJurnal

This is a retrospective study evaluating the risk factors for clinical anastomotic leakage after anterior resection in 64 patients with rectal cancer operated from November 2001 till August 2003. The percentage of anastomosis leakage was higher in those patients with diabetic, low albumin level, neoadjuvant radiotherapy, higher staging, and poorly differentiated tumour. However, these differences were statistically not significant. There was a significant difference (p=0.03) of anastomosis leakage in those patients with very distal tumour of < 4cm from anal verge (42%), when compare to those patients with proximal tumor of > 15cm from anal verge (4.3%). The mortality associated with this complication was 30%. Hence, a surgeon may consider a covering stoma or be more vigilant in operating patients with multiple risk factors.

Med J Malaysia, 1994 Sep;49(3):310-4.

PMID: 7845289

Continent pouch ileostomy is fashioned for patients who need a proctocolectomy. It is usually indicated for cases of ulcerative colitis and familial adenomatous polyposis where the anal sphincter can no longer maintain normal function or has to be removed. A case of familial adenomatous polyposis with features of Gardner's syndrome is reported. The patient presented with carcinoma of the rectum. Abdominoperineal resection followed by completion pancolectomy was performed. A continent pouch ileostomy was fashioned for him. He resumed work as a labourer within six months. The pouch was troublefree, needed to emptied four to six times a day and was fully continent of fluid, flatus and faeces until his demise three years later from liver secondaries. Continent pouch ileostomy is a better alternative than permanent end ileostomy. All care should be taken to rule out the existence of Crohn's disease. It is proposed that continent pouch ileostomy should be offered to patients needing permanent ileostomy if the expertise is available.

Fulltext Immunohistochemical Study of p53 Expression in Premalignant and Malignant Cervical Neoplasms

Tan, GC, Sharifah, N.A., Salwati, S., Hatta, A.Z., Shiran, M.S, Ng, Ho

Medicine & Health, 2007;2(2):125-132.

MyJurnal

One of the most important cervical cancer risk factors is human papillomavirus (HPV) infection. The p53 gene is one of the most important targets of the HPV E6 gene. E6 protein has the ability to stimulate p53 degradation, inhibits several functions of wild-type p53 and it competes with its function including suppression of malignant growth. The aim of this study is to determine the differences in p53 expressions in pre-malignant and malignant cervical neoplasms. This is a retrospective study on 100 cases of cervical neoplasms. There were 21 cases of CIN 1, 8 cases of CIN 2, 25 cases of CIN 3, 36 cases of squamous cell carcinoma, 7 cases of adenocarcinoma and 3 cases of adenosquamouscarcinoma. All cases were evaluated by immunohistochemistry using p53 monoclonalantibody. Thirty six of the 54 pre-malignant cases (66.7%) were positive for p53 protein, n contrast to the malignant cases in which, 40 of the 46 cases (87.0%) were positive. he majority of CIN showed absent to focal staining (29/54, 53.7%). In contrast, 84.8% (39/46( of the invasive carcinoma showed regional to diffuse staining. The expression of p53 is greater in the malignant cervical neoplasms than the pre-malignant cervical lesions, suggesting that p53 overexpression is not an early phenomenon in the pathogenesis of cervical cancer. It is also shown to be slightly higher in percentage in CIN 2 and 3 when compared with CIN 1. However, a number of cases were p53 negative, suggesting that other factors may be involved and further HPV studies are indicated.

J Inorg Biochem, 2015 Sep;150:48-62.

PMID: 26086852 DOI: 10.1016/j.jinorgbio.2015.06.009

In the solid state each of three binuclear zinc dithiocarbamates bearing hydroxyethyl groups, {Zn[S2CN(R)CH2CH2OH]2}2 for R = iPr (1), CH2CH2OH (2), and Me (3), and an all alkyl species, [Zn(S2CNEt2)2]2 (4), features a centrosymmetric {ZnSCS}2 core with a step topology; both 1 and 3 were isolated as monohydrates. All compounds were broadly cytotoxic, specifically against human cancer cell lines compared with normal cells, with greater potency than cisplatin. Notably, some selectivity were indicated with 2 being the most potent against human ovarian carcinoma cells (cisA2780), and 4 being more cytotoxic toward multidrug resistant human breast carcinoma cells (MCF-7R), human colon adenocarcinoma cells (HT-29), and human lung adenocarcinoma epithelial cells (A549). Based on human apoptosis PCR-array analysis, caspase activities, DNA fragmentation, cell apoptotic assays, intracellular reactive oxygen species (ROS) measurements and human topoisomerase I inhibition, induction of apoptosis in HT-29 cells is demonstrated via both extrinsic and intrinsic pathways. Compounds 2-4 activate the p53 gene while 1 activates both p53 and p73. Cell cycle arrest at the S and G2/M phases correlates with inhibition of HT-29 cell growth. Cell invasion is also inhibited by 1-4 which is correlated with down-regulation of NF-κB.

PMID: 10958943

Tumor cytogenetic analysis from 27 patients with breast cancer diagnosed at the Singapore General Hospital revealed complex karyotypic aberrations in 12 cases. The study group comprised 25 women and 2 men, ranging in age from 33 to 78 years (median 52 years). Ethnic distribution consisted of 22 Chinese, 3 Malaysian, and 2 Indian patients. Pathologic assessment disclosed 24 invasive ductal, 2 invasive mucinous, and 1 mixed invasive mucinous and ductal carcinomas. Histologic grading showed 3 grade 1, 10 grade 2, and 12 grade 3 tumors; 2 cancers were not graded, because they had been subjected to prior chemotherapy. Tumor sizes ranged from 1.5 to 10 cm (median 3 cm). Eleven cases were axillary node negative, whereas the remaining 16 node-positive cancers affected as many as 3 nodes in 8 cases and 4 or more nodes in another 8. Twenty cases demonstrated estrogen-receptor positivity, and 8 cases progesterone-receptor positivity. The spectrum of cytogenetic abnormalities involved chromosomes 1, 3, 6, 7, 8, 11, 16, and 17 and ranged from gains and deletions of both long and short arms, trisomy, monosomy, and other rearrangements. There was a trend toward the presence of karyotypic abnormalities in tumors of higher grade.
