Since the year 2000, lung cancer has become the leading cause of cancer death in South Korea as in many other parts of the world. The current multidisciplinary approach for lung cancer includes a wide range of modalities, not only surgery, radiotherapy, medical drug therapy but also pain control, as well as social and psychological support. Therefore, thoracic surgeons, radiologists, nuclear medicine specialists, anesthetists, psychologist, nurses and social workers as well as medical doctors care for lung cancer patients. Sharing a common treatment protocol and optimal communication are vital aspects of shared care both from a medical and cost-effectiveness point of view. We developed a shared electronic medical record (SEMR) for treating patients with lung cancer in a university hospital to facilitate the sharing protocols and communications between doctors involved in a lung cancer clinic. A SEMR system was developed within a order communication system(OCS) for a lung cancer clinic. The records of radiological, laboratory and pathological studies as well as the records of surgery, chemotherapy, and radiotherapy were stored and presented to all doctors who treat the same patient. Every doctor was allowed to change his/her own records. They could review other doctor s records but could not alter them. With the SEMR, it was expected that the time to complete the medical records for one patient could be reduced because it was easy to review all the data from the other doctors who share the same patient. In addition, the confidence of the doctors who share a common treatment protocol would be higher. Therefore, a shared electronic medical record is expected to improve the quality of patient care.

Background: In Iran, breast cancer is the most prevalent cancer in women and a major public health problem. Methods: A cross sectional study was carried out to determine knowledge on breast cancer and breast self-examination (BSE) practices of 384 females living in the city of Hamadan, Iran. A purposive sampling method was adopted and data were collected via face-to-face interviews based on a validated questionnaire developed for this study. Results: Among respondents 268 (69.8%) were married and 144 (37.5%) of the respondents reported having a family history of breast cancer. One hundred respondents (26.0%) claimed they practiced BSE. Level of breast cancer knowledge was significantly associated with BSE practice (p=0.000). There was no association with demographic details (p<0.05). Conclusion: The findings showed that Iranian women's knowledge regarding breast cancer and the practice of BSE is inadequate. Targeted education should be implemented to improve early detection of breast cancer.

The purpose of this study was to determine how nurses recognize the need for supportive care of advanced cancer patients and to provide preliminary data on how adequate circumstances are to be set up and maintained in Korea. For the purpose of this study, we developed a preliminary questionnaire based on a focus group of 8 nurses run by a clinical psychologist and administered it to 228 nurses in a cancer hospital, over a 3-month period. Participants of this study were nurses with more than 5 years' experience of treating advanced cancer patients. The result showed that 207 respondents (90.8%) agreed that a smooth communication system for treatment taking into account the symptoms experienced by patients and rehabilitation issues was needed. More than 80% agreed that the items needed for an integrated management service for advanced cancer patients should include psychological support, an integrated pain and symptom management, and education for the patient and his or her caregivers. These results strongly suggest that a new system distinct from palliative care or hospices is needed for patients with advanced cancer in Korea.

Small extracellular vesicles (sEVs) secreted by most cells carry bioactive macromolecules including proteins, lipids, and nucleic acids for intercellular communication. Given that some immune cell-derived sEVs exhibit anti-cancer properties, these sEVs have received scientific attention for the development of novel anti-cancer immunotherapeutic agents. In this paper, we reviewed the latest advances concerning the biological roles of immune cell-derived sEVs for cancer therapy. sEVs derived from immune cells including dendritic cells (DCs), T cells, natural-killer (NK) cells, and macrophages are good candidates for sEV-based cancer therapy. Besides their role of cancer vaccines, DC-shed sEVs activated cytotoxic lymphocytes and killed tumor cells. sEVs isolated from NK cells and chimeric antigen receptor (CAR) T cells exhibited cytotoxicity against cancer cells. sEVs derived from CD8⁺ T and CD4⁺ T cells inhibited cancer-associated cells in tumor microenvironment (TME) and activated B cells, respectively. M1-macrophage-derived sEVs induced M2 to M1 repolarization and also created a pro-inflammatory environment. Hence, these sEVs, via mono or combination therapy, could be considered in the treatment of cancer patients in the future. In addition, sEVs derived from cytokine-stimulated immune cells or sEV engineering could improve their anti-tumor potency.

Background: Research in the field of informational needs of breast cancer patients is scarce. In the few published articles, these needs were usually not satisfied. The main objective of this study was to evaluate satisfaction regarding informational needs in women with breast cancer. The long-term goal was to guide physician-patient communication to meet these needs. Materials and Methods: A survey with 21 questions was completed by 84 female patients receiving chemotherapy in a one-day hospital in Beirut, Lebanon. All patients were aware of their disease and agreed to participate in the survey. Results: The doctor was the major source of information for patients followed by media (radio and television). The level of knowledge of patients concerning their disease was proportional to the number of information sources. Women aged younger than 45 years, diagnosed during the last three months before the survey and certified from high school were less satisfied with information given by the oncologist. The missing information was in relation with the steps of the treatment after the chemotherapy regimen, the risk of a family member (sisters and daughters) of developing the disease and management of lymphedema. Conclusions: This study generated a scale for the degree of satisfaction of information received by women with breast cancer from their oncologist. The physician can use this scale to improve his or her skills of communication to patients and diminish their level of fear and anxiety.

Breast cancer ranks among the most prevalent forms of malignancy and foremost cause of death by cancer worldwide. It is not preventable. Early and precise detection is the only remedy for lowering the rate of mortality and improving the probability of survival for victims. In contrast to present procedures, thermography aids in the early diagnosis of cancer and thereby saves lives. But the accuracy experiences detrimental impact by low sensitivity for small and deep tumours and the subjectivity by physicians in interpreting the images. Employing deep learning approaches for cancer detection can enhance the efficacy. This study explored the utilization of thermography in early identification of breast cancer with the use of a publicly released dataset known as the DMR-IR dataset. For this purpose, we employed a novel approach that entails the utilization of a pre-trained MobileNetV2 model and fine tuning it through transfer learning techniques. We created three models using MobileNetV2: one was a baseline transfer learning model with weights trained from ImageNet dataset, the second was a fine-tuned model with an adaptive learning rate, and the third utilized early stopping with callbacks during fine-tuning. The results showed that the proposed methods achieved average accuracy rates of 85.15%, 95.19%, and 98.69%, respectively, with various performance indicators such as precision, sensitivity and specificity also being investigated.

Background: Despite increasing debate about overdiagnosis and overtreatment of thyroid cancer in Korea, information to guide decisions on whether or not to undergo screening for and treatment of abnormal lesions of the thyroid is lacking. Moreover, studies have yet to outline what lay people know and want to know about thyroid cancer. The primary aim of this study was to explore general awareness of thyroid cancer among Korean women, their sources of information, and their satisfaction with the information they are provided. The secondary aim was to investigate information needs about thyroid cancer. Materials and Methods: A qualitative study using focus group interviews was conducted. Twenty-nine women were divided into four groups: (1) participants who had never undergone thyroid ultrasound screening; (2) those who had undergone screening, (3) those who continued to undergo regular check-ups with ultrasonography for benign nodules of the thyroid; and (4) participants who had undergone surgery for thyroid cancer. Results: A widespread lack of awareness of information on thyroid cancer was noted among participants in groups 1 and 2 who were not well aware of thyroid cancer and generally recognized it as a 'good cancer'. Surprisingly, instead of doctors and medical personnel, most participants reported obtaining information from acquaintances and media outlets. Moreover, most participants described dissatisfaction with their experience with screening and a lack of explanation on treatment and test results from medical personnel. Conclusions: Women in Korea seek reliable information on thyroid cancer that could help them to better understand the disease and make informed decisions regarding screening and treatment. More effort is needed from medical personnel to communicate the implications of thyroid cancer, screening results, and treatments thereof to lay people.
