The Role of Radiation Oncologist in Palliative Care Conferences in Cancer Hospital

Sometimes palliative radiotherapy (pRT) is not always used appropriately. In our institution, radiation oncologists started to participate the palliative care conferences from September 2021. Between September 2021 and August 2022, 26 (7.6%) of 341 patients presented at this conference were considered candidates for pRT. Finally, 11 patients (3.2%) underwent pRT (ulcerative breast cancer, 2; metastatic spinal cord compression, 1; re-irradiation, 6; peritoneal dissemination, 1; multiple liver metastases, 1). The participation of radiation oncologists at the palliative care conference is thought to facilitate the treatment option of palliative radiotherapy.

Patient-related Factors Contributing to Shorter Prognosis than Oncologist’s Estimation of Survival in Terminal Cancer

Objective: To investigate the factors that make observed survival of patients with terminal cancer shorter than oncologists’ estimation. Methods: We retrospectively surveyed the medical records of terminal cancer patients who were referred to our palliative care unit with a predicted survival of 1–3 months and discharged dead from hospital within 3 months. Results: A total of 249 patients were eligible for analysis. One hundred and two patients (41%) had observed survival of less than one month (OS1), and 147 (59%) lived for 1–3 months (OS1–3) as expected. Depressed level of consciousness above Japan Coma Scale II and severely reduced oral intake (a few mouthfuls or less) were associated with unexpected shorter survival. The number of patients who died within two days after sudden deterioration of general condition was significantly higher in OS1 than OS1–3. Conclusion: Although survival of patients with the above factors may be shorter than oncologists’ estimation, it is necessary to examine the physician-side factors that contribute to the inaccuracy of prognosis.

Impact of institutional accreditation by the Japan Society of Gynecologic Oncology on the treatment and survival of women with cervical cancer / 부인종양

OBJECTIVE: The Japan Society of Gynecologic Oncology (JSGO) initiated a nation-wide training system for the education and certification for gynecologic oncologists in 2005. To assess the impact of the quality of the JSGO-accredited institutions, JSGO undertook an analysis of the Uterine Cervical Cancer Registry of the Japan Society of Obstetrics and Gynecology (JSOG) to determine the effectiveness of the JSGO-accredited institutions on the treatment and survival of women with cervical cancer. METHODS: The effectiveness of 119 JSGO-accredited institutions and 125 non-JSGO-accredited institutions on the treatment and survival of women with cervical cancer were compared by analyzing the tumor characteristics, treatment patterns, and survival outcomes of women with stage T1B–T4 cervical cancer utilizing the data in the JSOG nation-wide registry for cervical cancer (2006–2009). RESULTS: A total of 14,185 eligible women were identified: 10,920 (77.0%) cases for 119 JSGO-accredited institutions and 3,265 (23.0%) cases for 125 non-accredited institutions. A multivariate analysis showed that age, stage, histology type, and treatment pattern were independently associated with mortality. Moreover, women who received treatment at the JSGO-accredited institutions had a significantly decreased mortality risk compared to non-accredited institutions (adjusted hazard ratio [aHR]=0.843; 95% confidence interval [CI]=0.784–0.905). Similar findings on multivariate analysis were seen among subset of women who received surgery alone (aHR=0.552; 95% CI=0.393–0.775) and among women who received radiotherapy (aHR=0.845; 95% CI=0.766–0.931). CONCLUSION: Successful implementation of gynecologic oncology accrediting institution was associated with improved survival outcome of women with cervical cancer in Japan.

The work-relatedness at a case of acute lymphoblastic leukemia in a radiation oncologist

BACKGROUND: Clinicians who perform radiation therapy (RT) are exposed to radiation, which may negatively affect their health. The present study reports a case of acute lymphoblastic leukemia in a healthcare provider who was exposed to radiation at work; we also present a literature review of this topic. CASE PRESENTATION: A 45-year-old patient, who had been a radiation oncologist and had been exposed to radiation while performing brachytherapy 10 years ago, complained of chest pain and was suspected of having leukemia based on the results of a blood test in an outpatient clinic. He was diagnosed with acute lymphoblastic leukemia, and subsequently underwent chemotherapy. However, the case died during treatment. Through epidemiological investigation, it was found that the case's cumulative exposure dose based on personal exposure and spatial dose measured during the work period was in the range of 6.08–12.15 mSv. CONCLUSIONS: Based on the following considerations, acute lymphoblastic leukemia was highly correlated with the level of radiation to which the case was exposed while performing brachytherapy on patients with cancer. Firstly, the latent period of acute lymphoblastic leukemia in the case closely matched the latency time reported in previous published studies (5–10 years). In addition, numerous studies have reported significantly higher relative risks of cancer among clinicians who perform RT compared with the general population. The case was also atypically exposed to radiation through his hands, despite wearing protective equipment. Lastly, the case's coworkers were also found to have been exposed to high levels of radiation. Investigation into the influence of radiation exposure through atypical routes during RT on the health of clinicians is recommended.

The oncologists' views toward end-of-life discussions

End-of-life discussion with patients with advanced cancer is one of the important factors to determine the patient quality of life and their families' grief. The primary aim of this study is to collect Japanese medical oncologists' views toward end-of-life discussion. A context analysis of free comments of the questionnaire survey was conducted. Questionnaires were mailed to 864 medical oncologists, and 490 responses were obtained. A content analysis identified 420 free comments. As barriers of end-of-life discussion for oncologists, three types of barriers were emerged: 1) issues relating to patient and family (e.g., [individuality of the patient and family], [difficulty of acceptance of illness progression]), 2) issues relating to medical professionals (e.g., [a lack of psychological support], [difference in beliefs about end-of-life discussion among medical professionals]), and 3) health care systems (e.g., [a lack of time and human resources], [a lack of education and research]). The findings of this study may be useful to improve mutual understanding of oncologists and palliative care physicians when performing the end-of-life discussion in collaboration.

The Training Program That Integrated Palliative Care with Oncology

Currently, world-wide practice palliative care from early stage is underway. However, the practice has a variety of issues. “Palliative oncologist”- both trained Oncology and palliative care- have been proposed. Kawasaki municipal Ida hospital, from oncology ward, palliative care, and home in one sector and offers by using this system training programs have been conducted. Fellows can experience the anticancer treatment and palliative care. It may be useful Palliative oncologist training in Japan, and training program at our hospital would be a model.

Fibrocartilaginous Intramedullary Bone Forming Tumor of the Distal Femur Mimicking Osteosarcoma

Fibrocartilaginous dysplasia (FCD) has occasionally led to a misdiagnosis and wrong decision which can significantly alter the outcome of the patients. A 9-yr-old boy presented with pain on his left distal thigh for 6 months without any trauma history. Initial radiographs showed moth eaten both osteolytic and osteosclerotic lesions and biopsy findings showed that the lesion revealed many irregular shaped and sclerotic mature and immature bony trabeculae. Initial diagnostic suggestions were varied from the conventional osteosarcoma to low grade central osteosarcoma or benign intramedullary bone forming lesion, but close observation was done. This study demonstrated a case of unusual fibrocartilaginous intramedullary bone forming tumor mimicking osteosarcoma, so that possible misdiagnosis might be made and unnecessary extensive surgical treatment could be performed. In conclusion, the role of orthopaedic oncologist as a decision maker is very important when the diagnosis is uncertain.

A Comparison of Clinical Oncologists and Family Physicians toward Complementary and Alternative Medicine in South Korea: Perceptions, Attitudes and Physician-Patient Communication / 가정의학회지

BACKGROUND: Although, its efficacy is unclear, the application of complementary and alternative medicine (CAM) is increasing among patients worldwide. The physician's role is very important to help patients understand and use CAM properly. The aim of this study is to examine the perceptions, attitudes and physician-patient communication of about CAM in two distinguished specialty physicians. METHODS: A web-based survey was performed to list oncologists and family physicians in Korea between May 2007 and July 2007. E-mails were sent to total of 5,429 physicians and 547 physicians replied on survey (response rate: 10.1%). Of them, 500 participants comprising 174 clinical oncologists and 326 family physicians were involved in this study. The study questionnaire consisted of 26 questions including questions about general characteristics of CAM and intentions of introduction and education to their patients. RESULTS: Of 500 physicians, males were 73.4%, and 82.0% were middle-aged 30-49. Family physicians had more interest than oncologists about CAM (79.5% and 57.5%, respectively). In addition to, family physicians preferred introducing CAM to their patients than oncologists (34.1% and 18.4%, respectively). Almost 85% of the oncologists and family physicians thought that it was necessary to introduce CAM to their patients. However, 60.2% of them had hesitated their practice because 70.3% of them did not have sufficient knowledge in CAM. Both specialty physicians responded that usefulness of CAM information when regarding practice, should contain evidence-based evaluation (59.2%) and consensus guideline (37.0%). CONCLUSION: The results of this study showed that most physicians did not have sufficient information regarding CAM (87.2%). The result implies that evidence based information on complementaryand alternative medicine should be offered in the national level to improve communication between physicians and patients.

Current Status of SCI & SCIE Publications in the Field of Radiation Oncology in Korea / 대한방사선종양학회지

PURPOSE: To investigate current status of SCI (Science Citation Index) and SCI Expanded publications of Korean radiation oncologists. MATERIALS AND METHODS: Published SCI and SCIE articles the conditions of first author's address as "Korea" and "Radiation Oncology" or "Therapeutic Radiology" were searched from Pubmed database. RESULTS: From 1990 to 2006, 146 SCI articles and 32 SCIE articles were published. Most frequently published journal was International Journal of Radiation Oncology Biology Physics, where 56 articles were found. Articles with 30 or more citations were only five and 10 or more citations were 26. Yonsei University, which had 57 published articles, was the top among 19 affiliations which had one or more SCI and SCIE articles. Authors with five or more articles were 9 and Seong J. of Yonsei University was the top with 19 articles. CONCLUSION: The investigations showed disappointing results. The members of Korean Society of Radiation Oncologists must consider a strategy to increase SCI and SCIE publications.

Number of Radiation Oncologists in Korea, Adequate or Surplus? / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The purpose of this research is to discern and address the issues related to the radiation oncology manpower supply and its distribution. MATERIALS AND METHODS: The statistical data of the Annual Report of the Korea Central Cancer Registry (KCCR) from 1997 to 2002 and the Annual Report of the Korean Society of Radiation Oncology (KOSTRO) from 1997 to 2004 were used to predict the status of the human resources in 2015. The estimated demand and supply were calculated with the Microsoft Excel(R) program (Microsoft, Redmond, WA). RESULTS: The demand for radiation oncologists is estimated to be 161 in 2015 and about 4.9 radiation oncologists will be in demand annually. In contrast, an average of 15 new radiation oncologists will be supplied annually so that the accumulated surplus of radiation oncologists until 2015 is estimated to be 74.1. The main reason for the surplus comes from the discrepancy between the increased number of radiation therapy patients and the need for radiation oncologists. When there is an increase of 1,000 radiation therapy patients, the demand for radiation oncologists increases only by 2.4. This phenomenon is especially evident in the top 10 hospitals where the average number of radiation therapy patients per radiation oncologist is 341, which is 58% higher than the average number (215) of other 46 hospitals. CONCLUSION: To prevent a surplus and to maintain the quality of management, the number of radiation therapy patients per radiation oncologist should be limited. Furthermore, coordinate control of the number of residency positions should be seriously considered.
