Recent reports have dispelled the previously held concept that head and neck cancer rarely metastases beyond the cervical lymph nodes. Nasopharyngeal cancer has been reported to have a higher incidence of distant metastases compared to other head and neck cancers, the common sites being bone, lung and liver. A case of nasopharyngeal carcinoma presenting as obstructive jaundice because of secondaries at the porta hepatis is presented here.

ETHNOPHARMACOLOGICAL RELEVANCE: Locally known as 'pecah batu', 'bayam karang', 'keci beling' or 'batu jin', the Malaysian medicinal herb, Strobilanthes crispus (S. crispus), is traditionally used by the local communities as alternative or adjuvant remedy for cancer and other ailments and to boost the immune system. S. crispus has demonstrated multiple anticancer therapeutic potential in vitro and in vivo. A pharmacologically active fraction of S. crispus has been identified and termed as F3. Major constituents profiled in F3 include lutein and β-sitosterol.

AIM OF THE STUDY: In this study, the effects of F3, lutein and β-sitosterol on tumor development and metastasis were investigated in 4T1-induced mouse mammary carcinoma model.

MATERIALS AND METHODS: Tumor-bearing mice were fed with F3 (100 mg/kg/day), lutein (50 mg/kg/day) and β-sitosterol (50 mg/kg/day) for 30 days (n = 5 each group). Tumor physical growth parameters, animal body weight and development of secondary tumors were investigated. The safety profile of F3 was assessed using hematological and histomorphological changes on the major organs in normal control mice (NM).

RESULTS: Our findings revealed significant reduction of physical tumor growth parameters in all tumor-bearing mice treated with F3 (TM-F3), lutein (TM-L) or β-sitosterol (TM-β) as compared with the untreated group (TM). Statistically significant reduction in body weight was observed in TM compared to the NM or treated (TM-F3, TM-L and TM-β) groups. Histomorphological examination of tissue sections from the F3-treated group showed normal features of the vital organs (i.e., liver, kidneys, lungs and spleen) which were similar to those of NM. Administration of F3 to NM mice (NM-F3) did not cause significant changes in full blood count values.

CONCLUSION: F3 significantly reduced the total tumor burden and prevented secondary tumor development in metastatic breast cancer without significant toxicities in 4T1-induced mouse mammary carcinoma model. The current study provides further support for therapeutic development of F3 with further pharmacokinetics studies.

Fulltext What is obesity doing to your gut?

Lee YY

Malays J Med Sci, 2015 Jan-Feb;22(1):1-3.

PMID: 25892944

Obesity is a fast-emerging epidemic in the Asia-Pacific region, with numbers paralleling the rising global prevalence within the past 30 years. The landscape of gut diseases in Asia has been drastically changed by obesity. In addition to more non-specific abdominal symptoms, obesity is the cause of gastro-oesophageal reflux disease, various gastrointestinal cancers (colorectal cancer, hepatocellular carcinoma, oesophageal adenocarcinoma, gastric cardia adenocarcinoma, pancreatic cancer and gallbladder cancer) and non-alcoholic fatty liver disease. Abnormal cross-talk between the gut microbiome and the obese host seems to play a central role in the pathogenesis, but more studies are needed.

Chandran R, Rahman H, Gebbie D

Aust N Z J Obstet Gynaecol, 1993 Nov;33(4):437-9.

PMID: 8179566

This case represents a unique primary ovarian tumour consisting of malignant mucinous elements and granulosa-theca-cell elements, the histogenesis of which remains uncertain. It also underscores the need for thorough sampling of mucinous tumours in order to discover a possible coexisting, different neoplastic component.

Intratumour amyloidosis in Malaysians: an immunohistochemical study

Looi LM

Ann Acad Med Singap, 1986 Jan;15(1):52-6.

PMID: 3010797

Congo red screening of tumour material examined at the Department of Pathology, University of Malaya revealed intratumour deposits of amyloid in 12% of nasopharyngeal carcinomas, 66% of basal cell carcinomas, 100% of medullary carcinomas of the thyroid, 56% of islet cell tumours of the pancreas, 1 out of 16 carcinoids and 1 out of 100 thyroid adenomas. All the deposits were permanganate resistant and did not contain AA protein, indicating that what was encountered was not secondary amyloid. The deposits showed variable staining for immunoglobulin light chains and amyloid P component with a standard peroxidase antiperoxidase method. The possibility that intratumour amyloid has a neoplastic origin is discussed.

Colorectal cancer (CRC) is one of the most common malignancies. In recent decades, early diagnosis and conventional therapies have resulted in a significant reduction in mortality. However, late stage metastatic disease still has very limited effective treatment options. There is a growing interest in using viruses to help target therapies to tumour sites. In recent years the evolution of immunotherapy has emphasised the importance of directing the immune system to eliminate tumour cells; we aim to give a state-of-the-art over-view of the diverse viruses that have been investigated as potential oncolytic agents for the treatment of CRC.

Choriocarcinoma is a rare neoplasia with a tendency of distant metastasis although highly sensitive to chemotherapy renders a good prognosis and outcome. Lungs, liver and cerebral metastasis are commonly implicated with maxillofacial region rarely involved. We illustrate a case of overwhelming metastatic choriocarcinoma to lungs, liver, brain and to the extreme of gum metastasis. Decompressive craniectomy for intracranial bleeding, multiple transfusions to correct anaemia and coagulopathy were done before high-risk-regime chemotherapy. Despite this, due to fulminant multi-organs involvement she finally succumbed to death. In conclusion, gum bleeding in choriocarcinoma may suggest metastasis and poor prognosis.

PMID: 21939176

We present a case of a middle-aged man who was incidentally found to have right renal solid mass while investigating for his left eye proptosis. Computerised tomography (CT) scan confirmed the diagnosis of renal cell carcinoma and the tumour was successfully excised via open surgery. The histopathology examination revealed the 10x7x8 cm mass to be a clear cell type renal cell carcinoma. The rare presentation of this metastatic renal cell carcinoma, its diagnosis and management will be discussed.

Med J Malaysia, 2012 Apr;67(2):210-1.

PMID: 22822646

Pancreatic metastases are very uncommon and originate most commonly from lung, colon, breast and kidney cancer. Ovarian adenocarcinoma has been reported as a primary site of pancreatic metastasis, but its diagnosis has rarely being reported by endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We report a case of multiple metastases to the pancreas from ovarian carcinoma occurring four years after original resection of the primary tumour. Our patient presented with severe epigastric pain which was initially treated as acute pancreatitis. Further imaging modalities showed multiple large pseudocystic lesions in the pancreatic head and body. Subsequent EUS-FNA confirmed that the lesions were metastatic disease from an advanced ovarian carcinoma. She underwent palliative chemotherapy and the pancreatic lesion showed receding size.

Fulltext ACTH producing pulmonary carcinoid and pituitary macroadenoma: a fortuitous association?

Wong M, Isa SH, Kamaruddin NA, Khalid BA

Med J Malaysia, 2007 Jun;62(2):168-70.

PMID: 18705457

We report a case of a 45 year-old man who presented initially with a non-functioning pituitary macroadenoma. A routine chest radiography done preoperatively revealed a right lung nodule which was confirmed by computed tomography (CT) of the thorax. Transfrontal hypophysectomy was performed while a conservative approach was taken for the lung nodule. Four years later, he presented acutely with adrenocorticotrophic hormone (ACTH) dependent Cushing's syndrome which resolved following a right lobectomy. Histological examination revealed an atypical carcinoid. To our knowledge, this is the first reported case of an ectopic ACTH secreting pulmonary carcinoid found in association with a non-functioning pituitary macroadenoma.

Classification of Chinese cancer patients by dialect group: is it still valid?

Lee HP, Gourley L

Ann Acad Med Singap, 1988 Jul;17(3):431-3.

PMID: 3265301

In Singapore, cancer incidence is documented separately for the different Chinese dialect groups, as a means of providing a possible insight into environmental or genetic factors which may be involved in the aetiological process. Thus, it would be useful to determine whether or not the Chinese population in Singapore still comprises distinct dialect groups. In view of this, an investigation into the dialect group of the parents of 792 hospital in-patients (cases and controls) was carried out. It was found that the vast majority of patients (94.2%), most of whom were born before 1940, had parents of the same dialect group. The percentages of within-dialect marriages were only slightly less for offspring born in Singapore or Malaysia as opposed to China, and decreases with time were small. Thus in 1985-87 Chinese cancer patients and controls in Singapore, of the ages represented in this study may indeed be classified according to their father's dialect and this is likely to be the case for at least the next decade or so. This finding will be of use to cancer epidemiologists as well as others studying Chinese dialect group variations in disease patterns.

Kathmandu Univ Med J (KUMJ), 2018 7 1;16(63):272-274.

PMID: 31719321

Inflammatory myofibroblastic tumour is rare but more common in children. It shows an immunophenotypic features of myofibroblastic differentiation, hence bearing neoplastic potential. The diagnosis is challenging especially if it involves rectum. Surgical resection is the mainstay of treatment if clinically obstructed. A 65-year-old gentleman presented with intestinal obstruction, which then followed by a hartmann's procedure. Final diagnosis is a rare case of inflammatory myofibroblastic tumour of the rectum. We discuss its genetic involvement with a literature review.

MicroRNAs (miRNAs) have important roles in all biological pathways in multicellular organisms. Over 1,400 human miRNAs have been identified, and many are conserved among vertebrates and invertebrates. Regulation of miRNA is the most common mode of post-transcriptional gene regulation. The miRNAs that are involved in the initiation and progression of cancers are termed oncomiRs and several of them have been identified in canine and human cancers. Similarly, several miRNAs have been reported to be down-regulated in cancers of the two species. In this review, current information on the expression and roles of miRNAs in oncogenesis and progression of human and canine cancers, as well the roles miRNAs have in cancer stem cell biology, are highlighted. The potential for the use of miRNAs as therapeutic targets in personalized cancer therapy in domestic dogs and their possible application in human cancer counterparts are also discussed.

Chan RS, Kumar G, Vijayananthan AA

Singapore Med J, 2013 Mar;54(3):e68-71.

PMID: 23546040

Breast metastases are uncommon and typically spread from contralateral breast carcinomas. Breast metastases that spread from extramammary malignancies are even less common, and account for 0.5%-6.6% of all malignant breast disease. As extrapulmonary metastases from osteosarcoma are uncommon, breast metastasis from osteosarcoma is extremely rare. We report a case of breast and peritoneal metastases from a tibial osteosarcoma 18 months after diagnosis, and 9 months after surgery and adjuvant chemotherapy. Computed tomography findings of multiple calcified and noncalcified tumour deposits in the lungs, pleura, peritoneum, chest wall and both breasts are described.

Chee CP

Singapore Med J, 1990 Feb;31(1):48-50.

PMID: 2333544

From 1973 to 1984, 119 patients presented to the Department of Neurosurgery, Royal Victoria Hospital, Belfast, with brain metastases, the primary sites of which remained unknown in 33 cases one month after discharge. About half of these cases were solitary and neurological lateralising signs were the commonest presentation. Of those cases in which surgery was performed, the majority remained improved one month after surgery. The one month mortality rate was only 3%. This study shows that with aggressive and appropriate treatment including surgical excision or decompression in solitary cases, an improved quality of life in the immediate postoperative period can be achieved in this particular group of brain metastases. A small number of patients remained alive and well after 6 months.

The anti-idiotype vaccines for immunotherapy

Bhattacharya-Chatterjee M, Chatterjee SK, Foon KA

Curr. Opin. Mol. Ther., 2001 Feb;3(1):63-9.

PMID: 11249733

Certain anti-idiotypic antibodies that bind to the antigen-combining sites of antibodies can effectively mimic the three-dimensional structures and functions of the external antigens and can be used as surrogate antigens for active specific immunotherapy. Extensive studies in animal models have demonstrated the efficacy of these vaccines for triggering the immune system to induce specific and protective immunity against bacterial, viral and parasitic infections as well as tumors. Several monoclonal anti-idiotype antibodies that mimic distinct human tumor-associated antigens have been developed and characterized. Encouraging results have been obtained in recent clinical trials using these anti-idiotype antibodies as vaccines. In this article, we will review the current literature and discuss the potential of this novel therapeutic approach for various human cancers.
