Survival and Prognostic Factors of Different Sites of Head and Neck Cancer: An Analysis from Thailand

BACKGROUND Head and neck cancers are prevalent in Thailand, in particular in the southern region of the country. However, survival with a large data set has not been reported. The purpose of the present study was to evaluate the survival figures and the prognostic factors in a cohort of patients treated in a university hospital located in the south of Thailand. PATIENTS AND METHODS Consecutive new cases of primary carcinoma of the oral cavity, oropharyx, hypopharynx and larynx, treated at Songklanagarind Hospital during 2002 to 2004, were analyzed. The 5-year overall survival rates were obtained by the Kaplan-Meier method. Prognostic factors were identified through multivariate Cox regression analysis. RESULTS A total 1,186 cases were analyzed. Two-thirds (66.6%) of the cases were at advanced stage (stage III and IV) at presentation. The five-year overall survivals for the whole cohort, oral cavity, oropharynx, hypopharynx and larynx were 24.1%, 25.91%, 19.2%, 13.4%, 38.0% respectively. Stage and treatment type were strong prognostic factors for all sites. An age ≥80 years was associated with poor survival in oral cavity and larynx cancer. CONCLUSIONS The results revealed remarkably poor outcomes of the patients in the series, indicating a strong need to increase the proportion of early stage presentations and maximize the treatment efficacy to improving outcomes. Very old patients are of particular concern for treatment care of oral cavity and larynx cancer.

Disclosure of a cancer diagnosis in Thai patients treated with radiotherapy

Although radiotherapy usually implies a cancer diagnosis, no available study has been reported as to what proportion of Thai patients treated with radiotherapy know their diagnosis and how they want related information revealed. We questioned 106 patients in order to determine the proportion who knew their cancer diagnosis, and interviewed patients who knew the diagnosis and relatives of patients both who knew and did not know it with semi-structured questionnaires concerning how they wanted to be told. Sixty-seven patients (63.2%) knew their cancer diagnosis. Multivariate analysis showed that the patients with the following characteristics were inclined to know their diagnosis: younger than 70 years old, head and neck or gynecological cancer, no previous treatment before radiotherapy, no accompanying relatives during the treatment, and patients with relatives who wanted to disclose the information. 97.0% of patients who knew the diagnosis indicated that they had really wanted to know, 89.5% and 73.3%, respectively of relatives who accompanied patients who knew and did not know it expressed the same wish. No demographic factors could predict who wanted to be told the diagnosis. The majority of patients and relatives who wanted the diagnosis disclosed wanted to know all related information before treatment. They wanted to hear this directly from the doctor in the presence of their relatives.

Palliative care development in the Asia-Pacific region: an international survey from the Asia Pacific Hospice Palliative Care Network (APHN)

Background Although palliative care is an important public healthcare issue worldwide, the current situation in the Asia-Pacific region has not been systematically evaluated. Objectives This survey aimed to clarify the current status of palliative care in the Asia-Pacific region. Methods Questionnaires were sent to a representative physician of each member country/region of the Asia Pacific Hospice Palliative Care Network (APHN). The questionnaire examined palliative care service provision, information regarding physician certification in palliative care, the availability of essential drugs for palliative care listed by the International Association for Hospice and Palliative Care (IAHPC) and the regulation of opioid-prescribing practice. Results Of the 14 member countries/regions of the APHN, 12 (86%) responded. Some form of specialist palliative care services had developed in all the responding countries/regions. Eight member countries/regions had physician certifications for palliative care. Most essential drugs for palliative care listed by the IAHPC were available, whereas hydromorphone, oxycodone and transmucosal fentanyl were unavailable in most countries/regions. Six member countries/regions required permission to prescribe and receive opioids. Conclusions The development of palliative care is in different stages across the surveyed countries/regions in the Asia-Pacific region. Data from this survey can be used as baseline data for monitoring the development of palliative care in this region.

Regulation of opioid drugs in Thai government hospitals: Thailand national survey 2012

Context: Palliative care in Thailand was not well developed in the past. Previous studies showed that the actual prescription of opioids was underutilized in palliative care by physicians compared with the estimated opioid need of patients. However, there were no studies regarding the regulation of opioids in Thailand. Aims: To provide an up-to-date overview of the role of multidisciplinary teams in the regulation of opioids in Thai government hospitals. Settings and Design: A questionnaire survey study was conducted from January to April 2012. Materials and Methods: The questionnaire was distributed to entire population of government hospitals in Thailand and all private hospitals in Bangkok. There were 975 hospitals, including 93 private hospitals in Bangkok and 882 government hospitals. Statistical analysis used: Results are presented as a frequency and percentage. Results: Special opioid prescription forms must be signed by doctors for all opioid prescriptions. Three-fourths of hospitals totally prohibited prescribing oral opioids by palliative care Advance Practice Nurses. Pharmacists were permitted to correct the technical errors on a prescription of oral morphine only after notifying the prescribing doctor in nearly 60% of hospitals. In terminal patients who could not go to the hospitals, caregivers were permitted to collect the opioids on behalf of patients in nearly 80% of hospitals. Conclusion: Our results illustrate that the regulation of opioids in government hospitals is mainly dependent on physician judgment. Patients can only receive oral morphine at a hospital pharmacy.

Moving Beyond Suffering: the Experiences of Thai Persons With Advanced Cancer.

Background: Cancer is a leading cause of death in Thailand; however, little research is available that describes the end-of-life experiences of cancer patients. Data presented here are part of a descriptive qualitative study that investigated dying experiences in patients with advanced cancer. Two core themes were identified—living with suffering and moving beyond suffering. In this publication, we focus on 1 of the core themes: moving beyond suffering. Objective: The objective of this study was to explore how Thai persons with advanced cancer move beyond suffering at the end of their life. Methods: A series of interviews and observations were conducted on 15 patients with terminal advanced cancer. The informants were followed through from the point of referral at the hospital to their death at home or in hospital. An inductive qualitative analysis was applied. Results: Thai persons with advanced cancer tried to find ways to go on living with suffering. Three themes emerged from the interview data: adopting religious doctrine, being hopeful, and being surrounded by the love and care of the family. Conclusions: This study highlights the roles of religious faith and spirituality in helping Thai patients transcend suffering and move on toward their end of life. Implications for Practice: Nurses need to be sensitive toward the religious faiths of their patients and provide culturally appropriate care for them. Nursing interventions to maintain hope and connectedness should be promoted by respecting the patients’ expressions of hope and supporting the involvement of family members in end-of-life care.

30 Years of Radiotherapy Service in Southern Thailand: Workload vs Resources

BACKGROUND To study the pattern of patient load, personnel and equipment resources from 30-years experience in Southern Thailand. MATERIALS AND METHODS This retrospective study collected secondary data from the Division of Therapeutic Radiology and Oncology and the Songklanagarind Hospital Tumor Registry database, Faculty of Medicine, Prince of Songkla University, during the period of 1982-2012. RESULTS The number of new patients who had radiation treatment gradually increased from 121 in 1982 to 2,178 in 2011. Shortages of all kinds of personnel were demonstrated as compared to the recommendations, especially in radiotherapy technicians. In 2011, Southern Thailand, with two radiotherapy centers, had 0.44 megavoltage radiotherapy machines (cobalt or linear accelerator) per million of population. This number is suboptimal, but could be managed cost-effectively by prolonging machine operating times during personnel shortages. CONCLUSIONS This study identified a discrepancy between workload and resources in one medical school radiotherapy center in.

Effects of Zinc Sulfate Supplementation on Cell-Mediated Immune Response in Head and Neck Cancer Patients Treated with Radiation Therapy

Zinc deficiency is an important factor that impairs cellular immunity and contributes to low T lymphocyte counts in head and neck cancers. Persistent T lymphopenia is clinically relevant in terms of tumor persistence and/or recurrence. The primary objective was to evaluate the impact of zinc sulfate supplementation on the absolute numbers of circulating T lymphocytes and T lymphocyte subpopulations. The secondary objectives were to evaluate overall survival, progression-free survival, and the adverse events of zinc sulfate. Seventy-two head and neck cancer patients were enrolled in a randomized, double-blind, placebo-controlled trial. Zinc sulfate 50 mg in 10 cc and an identically appearing placebo were self-administered 3 times daily at meal times. Blood samples were obtained for complete blood count, total T lymphocytes and T lymphocyte subpopulations before radiation therapy as baselines, at the fifth week during radiation therapy, and at the first month after completion of radiation therapy. The baseline characteristics of patients, tumors, and treatments and the baseline lymphocyte parameters were not significantly different between the 2 groups. Zinc sulfate supplementation during head and neck radiation therapy showed no increase in absolute numbers of circulating T lymphocytes, T lymphocyte subpopulations, or survival with acceptable side effects.

Situational Analysis of Palliative Care Education in Thai Medical Schools

Objective The Thai Medical School Palliative Care Network conducted this study to establish the current state of palliative care education in Thai medical schools. Methods A questionnaire survey was given to 2 groups that included final year medical students and instructors in 16 Thai medical schools. The questionnaire covered 4 areas related to palliative care education. Results An insufficient proportion of students (defined as fewer than 60%) learned nonpain symptoms control (50.0%), goal setting and care planning (39.0%), teamwork (38.7%), and pain management (32.7%). Both medical students and instructors reflected that palliative care education was important as it helps to improve quality of care and professional competence. The percentage of students confident to provide palliative care services under supervision of their senior, those able to provide services on their own, and those not confident to provide palliative care services were 57.3%, 33.3%, and 9.4%, respectively. Conclusions The lack of knowledge in palliative care in students may lower their level of confidence to practice palliative care. In order to prepare students to achieve a basic level of competency in palliative care, each medical school has to carefully put palliative care content into the undergraduate curriculum.

Palliative Care and Essential Drug Availability: Thailand National Survey 2012

BACKGROUND Palliative care in Thailand was not well established in the past, but it is better supported by many organizations at present. Despite the change in the situation, the availability of essential drugs for palliative care has not been well studied. OBJECTIVE Our aim was to update the medical community on the current situation of essential drug availability for palliative care in Thai hospitals. METHODS The International Association for Hospice and Palliative Care (IAHPC) list of 34 essential drugs for palliative care was used in this survey. RESULTS Five hundred and fifty-five hospitals replied to the questionnaire (response rate 57%). Eleven of the 24 nonopioid drugs were available above 90% in all hospitals. However, nonopioid drugs generally were less available in community hospitals (CH) and general hospitals (GH) than in large hospitals (LH). Tramadol was the most available weak opioid. Injectable morphine was the most available form of strong opioid in Thailand (96.9%). For the overall picture of oral morphine, immediate-release morphine was a less available form than the controlled-release form (32.2% versus 51.0%). Controlled-release oral morphine had a nearly two-fold better availability than immediate-release oral morphine in CH, GH, and LH, that is, cancer centers (CC), medical school hospitals (MH), regional hospitals (RH), and other government hospitals. In contrast, in private hospitals (PH), there was no difference between the availability of the controlled-release form and the immediate-release form. Transdermal fentanyl and methadone were also less available in Thailand (14.6% versus 16.5%, respectively). CONCLUSION LH and PH have better overall nonopioid and opioid medication availability than CH and GH.

Radiotherapy for brain metastases in southern Thailand: workload, treatment pattern and survival.

PURPOSE To study the patient load, treatment pattern, survival outcome and its predictors in patients with brain metastases treated by radiotherapy. MATERIALS AND METHODS Data for patients with brain metastases treated by radiotherapy between 2003 and 2007 were collected from medical records, the hospital information system database, and a population-based tumor registry database until death or at least 5 years after treatment and retrospectively reviewed. RESULTS The number of treatments for brain metastases gradually increased from 48 in 2003 to 107 in 2007, with more than 70% from lung and breast cancers. The majority were treated with whole brain radiation of 30 Gy (3 Gy X 10 fractions) by cobalt-60 machine, using radiation alone. The overall median survival of the 418 patients was 3.9 months. Cohort analysis of relative survival after radiotherapy was as follows: 52% at 3 months, 18% at 1 year and 3% at 5 years in males; and 66% at 3 months, 26% at 1 year and 7% at 5 years in females. Multivariate analysis demonstrated that the patients treated with combined modalities had a better prognosis. Poor prognostic factors included primary cancer from the lung or gastrointestinal tract, emergency or urgent consultation, poor performance status (ECOG 3-4), and a hemoglobin level before treatment of less than 10 g/dl. CONCLUSIONS This study identified an increasing trend of patient load with brain metastases. Possible over-treatment and under-treatment were demonstrated with a wide range of survival results. Practical prognostic scoring systems to assist in decision-making for optimal treatment of different patient groups is absolutely necessary; it is a key strategy for balancing good quality of care and patient load.
