    Radiotherapy has an established role in reducing the local relapses in breast cancer patients. The objective of this review was to investigate whether radiotherapy or its omission after breast surgery has measurable consequences on local tumor recurrence and patient survival. The late excess of cardiac deaths has also been published in various reports but important advances in the delivery of radiotherapy have overcome this problem to the extent that, excess cardiac deaths do not appear to be occurring in more recent trials. In this article some recent data, suggesting that radiotherapy following mastectomy and/or breast conserving surgery has a beneficial effect on survival is reviewed. Omission of radiotherapy is associated with a large increase in risk of ipsilateral breast tumor recurrence and with a small increase in the risk of patient's mortality.

    Adenoid cystic carcinoma (ACC) is a rare malignant tumor that arises within secretary glands, most commonly the major and minor salivary glands. It has a tendency for a prolonged clinical course, perineural invasion, with local recurrences and distant metastases. The three recognized histopathologic pattern of ACC are cribriform, tubular, and solid with the cribriform being most common. Standard treatment for salivary gland ACC is surgery and postoperative radiotherapy. We report a case of ACC of palate in a 30-year-old female and review the literature.

    Upper cervical chordoma (UCC) is rare condition and poses unique challenges to surgeons. Even though transoral approach is commonly employed, a minimally invasive technique has not been established. We report a 44-year old Malay lady who presented with a 1 month history of insidious onset of progressive neck pain without neurological symptoms. She was diagnosed to have an axial (C2) chordoma. Intralesional resection of the tumour was performed transorally using the Destandau endoscopic system (Storz, Germany). Satisfactory intralesional excision of the tumour was achieved. She had a posterior fixation of C1-C4 prior to that. Her symptoms improved postoperatively and there were no complications noted. She underwent adjuvant radiotherapy to minimize local recurrence. Endoscopic excision of UCC via the transoral approach is a safe option as it provides an excellent magnified view and ease of resection while minimizing the operative morbidity.

    It is well known that ionizing radiation has an onco-genetic activity and has been implicated in the causation of brain tumors. However, when a new growth appears adjacent to the site of previous tumor, the diagnosis is more toward recurrence. In addition to that, the possible cause might be overlooked, when it occurs many years after radiation treatment. We report a case of radiation-induced meningioma developed 20 years after the patient received radiotherapy for pituitary adenoma.

    Thymomas comprise about 1% of all mediastinal tumours and are rare in children. Typically, these tumours are aggressive, with a poor outcome. The current treatment of invasive thymoma is often multidisciplinary. We report a 16-year-old boy with invasive thymoma who was successfully treated with systemic chemotherapy, surgical resection and irradiation. The patient has been in continuous remission for 6 years without radiographic evidence of tumour recurrence.

    There are three types of papilloma which arises from the Schneiderian membrane namely inverted, fungiform and oncocytic. Oncocytic papilloma is the rarest type and occurs predominantly in the older age group. Clinically, its behaviour is similar to inverted papilloma in having both local recurrence and associated malignancy. We report a rare case of oncocytic papilloma arising from the maxillary sinus, extending into the nasal cavity and nasopharynx, in a 78-year-old lady. Despite the longstanding history there was no evidence of associated malignancy in this lesion. An endoscopic medial maxillectomy was successfully utilized for approach and complete tumour excision. In conclusion, oncocytic papilloma should be considered as a differential diagnosis in patients presenting with unilateral polypoid nasal lesions especially in the elderly. In addition, endoscopic medial maxillectomy can provide an adequate approach for complete tumour removal.

    Congenital intracranial tumors are rare and account for 0.5 to 1.5% of all childhood tumours. We report a case of a 3 week old baby presenting with multi compartmental congenital intracranial immature teratoma, first of its kind in the literature. The child had gross total excision in two stages with aid of neuronavigation. The short term outcome was good. The four years of follow-up with serial imaging showed no tumour recurrence with a stable hydrocephalus after shunting. However, there is global developmental delay with full time dependence of care giver.

    A 47-year-old lady, presented with progressive proptosis of left eye with deterioration of vision. She had a history of left solitary fibrous tumour and had undergone left frontal craniotomy and orbitotomy in 2004. Surveillance Magnetic resonance imaging (MRI) six years later showed tumour recurrence with intracranial extension. However, she did not follow-up and only presented again 3 years, later. Tumour resection and left exenteration was performed. Histology showed ‘patternless’ pattern of neoplastic cells, and CD34 staining was diffusely positive. Diagnosis of recurrent solitary fibrous tumour with intracranial extension was made.

    Musculoskeletal tumour is much less common compared to tumours of epithelial origin. Most of these tumours are benign, with only about 1% malignant in nature. A general orthopaedic surgeon may only come across a malignant primary bone or soft tissue tumour a few times in his entire medical career. The current recommendation is for these conditions to be investigated and treated in centres with musculoskeletal oncology service. Careful clinical evaluation with appropriate plain radiography can provide adequate information for definitive diagnosis and treatment for most cases, especially the benign tumours. For some other cases, further investigations will be necessary. Magnetic resonance imaging (MRI) can provide excellent details on anatomical location of a tumour and delineate vital structures that may have been distorted by the lesion. For primary malignant tumours, computerized tomography scanning is still the gold standard for evaluation of pulmonary metastasis, and bone scan can allow early detection of distant metastasis to other bones. Whole body MRI has recently been recommended for tumour staging but the potential benefit for musculoskeletal tumour is not that convincing. PET may be very helpful for follow up detection of tumour recurrence but its role in diagnosis and staging of musculoskeletal tumours is still being evaluated...

    Respiratory papillomatosis is a disease of viral origin which is characterized by warty exophytic lesions in the aerodigestive tract. It is the most common benign lesion of larynx and the second most common cause of hoarseness in children. It has the tendency to recur and to spread through out the entire length of the aerodigestive tract. Although a benign disease, it has the potential of morbid consequences in view of airway complications and the risk of malignant transformation. We report a case of juvenile onset of respiratory papillomatosis and its therapeutic challenges.

    Epidermoid cysts are rare, benign congenital tumours of ectodermal origin which typically present between
    the third to fifth decade. These tumours comprise approximately 0.2-1.8% of all intracranial tumours. Though
    these pearly tumours are potentially curable, subtotal resection may lead to catastrophic complications such as
    recurrence, granulomatous meningitis and carcinomatous degeneration of cyst wall. We herein report the case
    of a 36-year-old man who presented with an unusual mixed density posterior fossa epidermoid cyst on imaging
    studies. Total removal not only cures both tumour and seizure attack in this case but also preserves patient’s
    neurological function.

    Lung cancer is the most common cancer worldwide, accounting for 1.8 million new cases and 1.6 million deaths in 2012. Non-small cell lung cancer (NSCLC), which is one of two types of lung cancer, accounts for 85-90% of all lung cancers. Despite advances in therapy, lung cancer still remains a leading cause of death. Cancer relapse and dissemination after treatment indicates the existence of a niche of cancer cells that are not fully eradicated by current therapies. These chemoresistant populations of cancer cells are called cancer stem cells (CSCs) because they possess the self-renewal and differentiation capabilities similar to those of normal stem cells. Targeting the niche of CSCs in combination with chemotherapy might provide a promising strategy to eradicate these cells. Thus, understanding the characteristics of CSCs has become a focus of studies of NSCLC therapies.

    AIM: Endoscopic endonasal nasopharyngectomy (EEN) for recurrent nasopharyngeal carcinoma (rNPC) is being increasingly used due to the added high magnification, reduced morbidities associated with open procedures and good survival outcomes. Most studies looked at usage of EEN in patients with lower recurrent staging (rT1 and rT2) although more and more surgeons are studying the outcome of EEN in advanced rNPC (rT3 and rT4). The aims of this study were to report the long-term 5-year survival outcome of EEN performed in patients with advanced rNPC, and to determine any prognostic factors for patients' survival.

    METHODS: All patients who underwent EEN for advanced rNPC between January 2003 and December 2015 inclusive were analyzed. All surgeries were performed in University Malaya Medical Centre in Kuala Lumpur and Queen Elizabeth Hospital in Sabah. We reported the 5-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors.

    RESULTS: Twelve patients with rNPC (2 rT3 and 10 rT4) were followed-up over a mean duration of 44.8 months (range, 40-440 weeks). The 5-year OS was 50.0% (mean 44.75 months), DFS was 25.0% (mean 35.25 months) and the DSS was 58.3% (mean 43.33 months). No severe operative complications were encountered and no independent prognostic factors for survival outcome were identified.

    CONCLUSION: This is the first report in English that exclusively described the long-term 5-year survival data in patients with both rT3 and rT4 recurrent NPC after EEN. The data suggest that EEN is a feasible treatment to improve survival with minimal morbidities in patients with rT3 and rT4 recurrent NPC. However, more studies with larger patient size is recommended.

    Transverse myelitis in multiple sclerosis is typically a short cord lesion with patchy distribution. Rarely, longitudinally extensive transverse myelitis can be seen in those with highly active disease or frequent relapses. The recognition of this uncommon phenotype in multiple sclerosis is important as the treatment is largely different from other demyelinating diseases. We describe a patient with highly active relapsing-remitting multiple sclerosis on interferon beta-1a who developed LETM after multiple relapses.

    Colorectal cancer (CRC) remains as one of the most common cause of worldwide cancer morbidity and mortality. Improvements in surgical modalities and adjuvant chemotherapy have increased the cure rates in early stage disease, but a significant portion of the patients will develop recurrence or advanced disease. The efficacy of chemotherapy of recurrence and advanced CRC has improved significantly over the last decade. Previously, the historical drug 5-fluorouracil was used as single chemotherapeutic agent. Now with the addition of other drugs such as capecitabine, irinotecan, oxaliplatin, bevacizumab, cetuximab, panitumumab, vemurafenib, and dabrafenib, the median survival of patients with advanced CRC has significantly improved from less than a year to the current standard of almost 2 years. However, the side effects of systemic therapy such as toxicity may cause fatal complications and have a major consequences on the patients' quality of life. Hence, there is an urgent need for key biomarkers which will enable the selection of optimal drug singly or in combination for an individual patient. The application of personalized therapy based on DNA testing could aid the clinicians in providing the most effective chemotherapy agents and dose modifications for each patient. Yet, some of the current findings are controversial and the evidences are conflicting. This review aims at summarizing the current state of knowledge about germline pharmacogenomics DNA variants that are currently used to guide therapeutic decisions and variants that have the potential to be clinically useful in the future. In addition, current updates on germline variants conferring treatment sensitivity, drug resistance to existing chemotherapy agents and variants affecting prognosis and survival will also be emphasized. Different alteration in the same gene might confer resistance or enhanced sensitivity; and while most of other published reviews generally stated only the gene name and codon location, we will specifically discuss the exact variants to offer more accurate information in this mini review.

    Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare variant of hepatocellular carcinoma. It is commonly reported in the younger population with no underlying chronic liver disease and free of viral Hepatitis B and C. Local recurrence and distant metastasis are common despite better prognosis compared to conventional hepatocellular carcinoma. Complete surgical resection is associated with higher median survival and is the mainstay treatment option for localized FL-HCC. Multi-modality therapies such as TACE can be used to downstage upfront unresectable FL-HCC. Complete response with GEMOX chemotherapy has been reported in advanced metastatic FL-HCC and should be considered in upfront unresectable or metastatic disease. We present a case of biopsied proven relapse FL-HCC with oligo- left lung metastasis who successfully underwent a left lung lobectomy after neo-adjuvant GEMOX chemotherapy, and is disease free at 24 months follow up.

    Fluctuation of BCR-ABL1 real-time quantitative polymerase chain reaction in International Scale (qPCRIS) level below major molecular response (MMR) (0.1%IS) is a known phenomenon after stopping tyrosine kinase inhibitor (TKI) in chronic myeloid leukaemia (CML) patients who are attempting treatment free remission (TFR). We report here four cases of fluctuation beyond MMR during conduct of a Malaysia Stop TKI Trial (MSIT) to examine the validity of the commonly used relapse criterion - loss of MMR for one reading - aiming to provide evidence in setting relapse criteria for future CML patients who want to attempt TFR.

    Quiescent cancer cells (QCCs), also known as dormant cancer cells, resist and survive chemo- and radiotherapy, resulting in treatment failure and later cancer recurrence when QCCs resume cell cycle progression. However, drugs selectively targeting QCCs are lacking. Saikosaponin A (SSA) derived from Bupleurum DC., is highly potent in eradicating multidrug-resistant prostate QCCs compared with proliferative prostate cancer cells. By further exacerbating the already increased autophagy through inactivation of Akt-mTOR signaling, SSA triggered cell death in QCCs. Contrarily, inhibition of autophagy or activation of Akt signaling pathway prevented SSA-induced cell death. The multicycle of Docetaxel treatments increased the proportion of QCCs, whereas administering SSA at intervals of Docetaxel treatments aggravated cell death in vitro and led to tumor growth arrest and cell death in vivo. In conclusion, SSA is posed as a novel QCCs-eradicating agent by aggravating autophagy in QCCs. In combination with the current therapy, SSA has potential to improve treatment effectiveness and to prevent cancer recurrence.

    INTRODUCTION: Breast conserving surgeries were previously contraindicated for central breast cancers because of poor cosmetic outcomes of central mastectomy without oncoplastic surgery. Grisotti flap is a breast-conserving surgery incorporating oncoplastic surgery technique for centrally located breast cancers. We present our experience and outcome from Breast Surgery Unit, University Malaya Medical Center.

    MATERIALS AND METHODS: A prospective analysis of 15 patients with central retroareolar breast cancer operated from 2012 to 2018 in University Malaya Medical Center. We assessed postoperative complications, margins, locoregional recurrence, and survival outcome. All patients received postoperative radiotherapy. Patients were followed-up 1 week, 1 month, 3 monthly for 1 year and 6 monthly for 5 years.

    RESULTS: Mean age of patients is 62 years. Mean follow-up is 51 months (15-84 months). All tumors were less than 5 cm (1-2.5 cm). Majority of the patients are stage 1 (6 patients/40%) and stage 2 (8 patients/ 53.3%). 2 patients had surgical site infection resolved with antibiotics. One patient had hematoma. None require reoperation. Tumor margins were clear in all patients. No locoregional recurrence. Overall survival is 100%. All are satisfied with their cosmetic outcomes.

    CONCLUSIONS: Grisotti flap is a volume displacement technique, which provides satisfactory cosmetic outcome for centrally located breast cancer. This evolutionary thinking leads us to changes in existing techniques with the purpose of achieving oncological safety while reaching for better esthetic results. Our 5 years' experience in Asian population showed that this technique is oncologically safe with good cosmetic outcomes and could be used selectively. It provides a good alternative in patients who are otherwise subjected for mastectomy. This relatively simple technique is a worthwhile endeavor and should be offered when feasible.
