INTRODUCTIONCommunication between patients and physicians is crucial in the disclosure of cancer diagnosis. Although westernisation of Asian societies has resulted in increased awareness of patient autonomy, the family continues to play an important influencing role in the disclosure process. Therefore, in this study, we aimed to characterise the experience of physicians with the disclosure of cancer diagnosis in a westernised Asian population.
METHODSOncologists at a tertiary hospital were approached to participate in this study. Information pertaining to the extent and approach to disclosure was collated. Logistic regression analysis was performed to characterise factors pertaining to the willingness of physicians to fully disclose a diagnosis of cancer.
RESULTSIn all, 25 oncologists (mean age 38 years; 72% men) responded to the survey. A majority of oncologists disclosed a cancer diagnosis directly to the patient over the first few visits. The main reason behind partial or non-disclosure was family objection. Ordinal logistic regression analysis showed that family resistance was the only significant predictor of reluctance to disclose a cancer diagnosis (p = 0.01).
CONCLUSIONIn this pilot study, contrary to previous reports, we found that oncologists were more likely to disclose a diagnosis of cancer to the patient first, that they do not accede fully to the family's request for non-disclosure and that family resistance was the only significant predictor of reluctance to disclose a diagnosis of cancer.

INTRODUCTIONAdvanced hepatocellular carcinoma (HCC) has a dismal prognosis and is notoriously chemo-resistant. We conducted a Phase II prospective study to evaluate the activity and tolerability of gemcitabine and cisplatin in chemo-naïve advanced hepatocellular carcinoma. The trial considered a "no further interest" response rate of 10% and a target response rate of 30%. Utilising a Simon's minimax two-stage design with a type I error of 0.05 and power of 80%, 25 subjects would be required. Fifteen patients would be needed in stage 1 and if fewer than 2 responses were observed, the trial would be stopped and lack of efficacy claimed.
MATERIALS AND METHODSPatients with advanced HCC, diagnosed based on histology or by World Health Organization (WHO) criteria, were administered gemcitabine 1000 mg/m2 and cisplatin 25 mg/m2 on day 1 and day 8 of a 21-day schedule. Assessment of response based on computer tomography was performed after every 2 cycles of chemotherapy.
RESULTSThe trial was stopped early due to a lack of efficacy. A total of 15 patients were accrued. Twelve patients were hepatitis B positive and the other 3 patients were negative for both hepatitis B and C. Only 1 patient had a history of prior heavy alcohol use. Two patients had Child C liver cirrhosis, 5 patients had Child B cirrhosis, and the remaining 8 patients had Child A cirrhosis. This regime was well tolerated and there was only 1 patient who experienced grade IV toxicities. Only 5 of 15 patients experienced grade III toxicities (nausea and emesis, 1 patient; anemia, 1 patient; thrombocytopenia, 1 patient; and neutropaenia, 2 patients). Only 1 patient experienced a partial response to the combination of gemcitabine and cisplatin. A further 3 patients experienced stable disease and 11 patients progressed on chemotherapy. The median time to progression was 6 weeks. The progression-free curve showed a sharp descent in the initial part of the study, suggesting that many patients had disease progression after enrollment. The median overall survival was 18 weeks.
CONCLUSIONThe progression-free survival and overall survival in our study were extremely short. Based on the results of our phase 2 study, we are unable to recommend further studies utilising gemcitabine and cisplatin combination in patients with advanced HCC.

INTRODUCTIONMore than half of all deaths in Singapore occur in hospitals. Little is known about the quality of care received by dying patients in hospitals. The Liverpool Care Pathway (LCP) provides a framework of providing good end-of-life care for dying patients and has been used with success in the United Kingdom (UK). In this study, we investigate whether adoption of a modified LCP in a Singapore hospital translated to better end-of-life care for cancer patients.
MATERIALS AND METHODSThe LCP was adapted and implemented as a pilot project on an oncology ward in Singapore General Hospital. A baseline review of 30 consecutive death records was performed, followed by a 4-month pilot and post-implementation audit of 30 consecutive patients on the adapted LCP.
RESULTSFive types of end-of-life symptoms were analysed. There was only 1 uncontrolled symptom at death in the post-implementation group compared to 24 uncontrolled symptoms in the retrospective audit group. The prescription of breakthrough medications for symptom control increased from 21% in the retrospective audit group to 79% in the post-implementation group. Inappropriate monitoring was discontinued in 25 patients in the post-implementation group compared to none in the retrospective audit group. The documentation of resuscitation status and religion of the patient was improved, achieving full documentation in the post-implementation group.
CONCLUSIONThis study shows promising results for improving end-of-life care in cancer patients with a protocol-based pathway in a Singapore hospital. Extension of this care pathway to other settings should be explored to maximise its benefits to patients dying from all causes in hospital.
