Medical infrared imaging is obtained by measuring the self-emitted infrared radiance from the human body. Infrared emission is related to surface temperature and temperature is one of the most important physiological parameters related to health. Though recent applications such as security identification and oriental medicine have provided new fields of biomedical applications, infrared thermography has had ups and downs in its usages in cancer detection. Some of the main difficulties include finding proper applications and efficient diagnostic algorithms. In this study, infrared thermal imaging was used to detect regional metastasis of breast cancer. Our measurements were done for 110 women. From 63 individuals of a Healthy Group and a Benign Breast Disease Group, we developed algorithms for differentiating malignant regional metastasis based on temperature difference and asymmetry of temperature distribution. Testing with 47 cancer patients, we achieved a positive predictive value of $87.5\%$ and a negative predictive value of $95.6\%$. The results were better than for mammogram examination. A proper analysis of infrared imaging proved to be a highly informative and sensitive method for differentiating regional cancer metastasis from normal regions.
Dyspnea is a common symptom among patients with gastrointestinal cancer, and a comprehensive evaluation of their respiratory function is essential. Self-reporting aids in the assessment of the degree of dyspnea, while objective examination methods are performed to identify the potential underlying causes when subjective symptoms are present. Standard treatment protocols should be followed for potentially reversible and common causes of dyspnea, such as pleural effusion, pneumonia, airway obstruction, anemia, asthma, exacerbation of chronic obstructive pulmonary disease, pulmonary thromboembolism, or drug-induced interstitial lung disease. Careful and close monitoring is required due to the high frequency of pulmonary thromboembolism and the risk of cardiovascular accidents, drug-induced interstitial lung disease, or other complications from some anticancer drugs. In case of hypoxemia with an oxygen saturation of 90% or less, palliative treatment should comprise standard oxygen therapy such as nasal cannula, mask, or high-flow nasal cannula. If non-pharmacological oxygen therapy is not effective, pain control through systemic narcotic analgesics and anti-anxiety therapy with benzodiazepines may be helpful.
Objectives : Cervical cancer is the second most frequent cancer among women in Busan. The Pap smear test could have a significant effect on detecting cervical cancer, and enhancing their rate of use is an important strategy for reducing the incidence and mortality of cervical cancer. This study aimed to evaluate the factors associated with the past use of the Pap smear test in Korean women. Methods : A population-based survey was carried out in Busan between November 1999 and March 2000. 1,673 participants were randomly selected from 2,684 women in Busan, using a 2-stage cluster sampling method, and interviewed in their homes. Their socio-demographic characteristics, smoking, drinking, familial cancer history, Pap smear screening history, reproductive and menstrual factors, sexual habits and use of contraceptive methods data were collected by a trained interviewer using a questionnaire. The use of the screening test was defined by a self-report from the participants on how many times they had had a Pap smear test in their lifetime, and when they had received their latest examination. Results : Of the 1,673 respondents (62.3% response rate), 57.6% had had a Pap smear test during her life (mean number, 2.3). Among the health examination participants(1,064), 961(90.3%) reported having sexual experience and 70.9% of these had had a Pap smear test. In a multiple logistic regression analysis, statistically significant relationships were observed for age groups and the Pap smear test rate (odds ratio, OR for 35-44 years=2.45; OR for 45-54 years=3.41; OR for 55 years=2.60; reference, under 34 years). The married or cohabiting women were more likely to have used the Pap smear test than those separated or widowed (OR=1.73). Among the reproductive behavioral measures, the number of births (OR for 3 births=4.22; OR for 2 births=3.95; OR for 1 births=3.38; reference, 0 births) and husband's extra-marital affairs (OR=1.50) were associated with the rates of use of Pap smear tests. Conclusion : It appears that the most important contributing factors to cervical cancer screening were age, marital status and number of births. A positive association was also observed for the husband's extra-marital affairs. This study enabled us to systematically assess the relationship between Pap smear rates and risk factors for cervical cancer. It is hoped that this study will make a significant contribution to the accumulating scientific evidence on the identification of factors associated with cervical cancer screening in Korea.
Background: Today, survival rate of patients with chronic renal failure/hemodialysis has increased so that chronic illnesses are more likely to occur. Cancer is the main cause of morbidity and mortality in such patients. Aim: In this study, physician attitudes were examined about cancer screening in patients with renal failure. Materials and Methods: This study was done by face to face questionnaire in the $27^{th}$ National Nephrology Congress to determine if the physicians dealing with chronic renal failure, hemodialysis or renal transplanted patients, recommend cancer screening or not and the methods of screening for cervix, prostate, breast and colon cancer. Results: One hundred and fifty six physicians were included in the survey. A total of 105 (67%) participants were male and the age of responders was $48{\pm}9$ years. About 29% were specialists in nephrology, 28% internal medicine, and 5% were other areas of expertise. Some 48% of participants were hemodialysis certified general practitioners. Patients were grouped as compensated chronic renal failure, hemodialysis or renal transplanted. Of the 156 responders, 128 (82%) physicians recommended breast cancer screening and the most recommended subgroup was hemodialysis patients (15%). The most preferred methods of screening were combinations of mammography, self breast examination and physicianbreast examination. 112 (72%) physicians recommended cervix cancer screening, and the most preferred method of screening was pap-smear. Colon cancer screening was recommended by 102 (65%) physicians and prostate screening by 109 (70%) physicians. The most preferred methods of screening were fecal occult blood test and PSA plus rectal digital test, respectively. Conclusions: It is not obvious whether cancer screening in renal failure patients is different from the rest of society. There is a variety of screening methods. An answer can be found to these questions as a result of studies by a common follow-up protocol and cooperation of nephrologists and oncologists.

Purpose: Early gastric cancer cases that are estimated to meet indications for treatment before endoscopic submucosal resection are often revealed to be out-of-indication after the treatment. We investigated the short-term treatment outcomes in patients with early gastric cancer according to the pretreatment clinical endoscopic submucosal resection indications. Materials and Methods: We retrospectively reviewed the medical records of patients with early gastric cancer that met the pretreatment endoscopic submucosal resection indications, from 2004 to 2011. Curative resection rate and proportion of out-of-indication cases were compared according to the pre-endoscopic submucosal resection indications. Pre-endoscopic submucosal resection factors associated with out-of-indication in the final pathological examination were analyzed. Results: Of 756 cases, 660 had absolute and 96 had expanded pre-endoscopic submucosal resection indications. The curative resection rate was significantly lower in the patients with expanded indications (64.6%) than in those with absolute indications (81.7%; P<0.001). The cases with expanded indications (30.2%) were revealed to be out-of-indication more frequently than the cases with absolute indications (13.8%; P<0.001). Age of >65 years, tumor size of >2 cm, tumor location in the upper-third segment of the stomach, and undifferentiated histological type in pre-endoscopic submucosal resection evaluations were significant risk factors for out-of-indication after endoscopic submucosal resection. Conclusions: Non-curative resection due to out-of-indication occurred in approximately one-third of the early gastric cancer cases that clinically met the expanded indications before endoscopic submucosal resection. The possibility of additional surgery should be empha-sized for patients with early gastric cancers that clinically meet the expanded indications.
Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore, laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologic findings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph node metastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, the diagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymph node metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful in determining the primary origin of lymph node metastasis.
Borrmann type 4 gastric cancers are notorious for the difficulty of finding cancer cells in the biopsy samples obtained from gastrofiberscopy. It is important to obtain the biopsy results for making surgical decisions. In cases with Borrmann type 4 gastric cancer, even though the radiological findings (such as an upper gastrointestinal series, abdominal computed tomography and positron emission tomography/computed tomography) or the macroscopic findings of a gastrofiberscopy examination imply a high suspicion of cancer, there can be difficulty in getting the definite pathologic results despite multiple biopsies. In these cases, we have performed endoscopic mucosal resection under gastrofiberscopy as an alternative to simple biopsies. Here we report on a case in which no cancer cells were found even in the endoscopic mucosal resection specimen, but the radiologic evidence and clinical findings were highly suspicious for gastric cancer. The patient finally underwent total gastrectomy with lymph node resection, and she was pathologically diagnosed as having stage IV gastric cancer postoperatively.
Background: This study conducted to determine breast cancer awareness and influencing factors among nursing students in the West Black Sea Region in Turkey. Materials and Methods: This cross-sectional descriptive study was conducted between April-May, 2014. The sample was 270 female nursing students. Data were collected by Personal Information Form and Champion's Health Belief Model Scale (CHBMS). Results: The students' mean age was $21.6{\pm}2.09$ and 81.1% had knowledge about breast cancer from their academic education. It is found that 63.7% of the students performed Breast Self-Examination (BSE) and 11.1% had a family member diagnosed with breast cancer. The CHBMS mean score of the students was $117.7{\pm}14.5$. Conclusions: Breast cancer awareness of nursing students is on a good level and was affected by family history of breast cancer and health beliefs.

Background: Endometrial cancer is the most common gynecological malignancy among females worldwide, approximately 320,000 women being diagnosed with the disease each year and 76,000 dying. To date, there is limited knowledge of endometrial cancer in Malaysia. Objectives: To identify the epidemiological profile and prognostic factors of survival. Materials and Methods: A list of endometrial cancer patients in 2000-2011 was obtained from the hospital Record Department. Only cases confirmed by histopathology examination were included. We excluded those with incomplete medical records or referral cases. Simple and multiple Cox regression approaches were used for data analysis. Results: Only 108 cases were included with a mean (SD) age of 62.7 (12.3) years, with 87.0% Malay ethnicity. Grade of cancer was: 29.1% grade 1, 43.7% grade 2 and 27.2% grade 3. The majority of patients had non-endometrioid type (60.2%), with myometrial invasion (82.2%) and lymphovascular invasion (57.3%). The significant prognostic factors were age (HR 1.05; 95% CI: 1.02, 1.08, p=0.002) and having lymphovascular invasion (HR 2.15; 95% CI: 1.08, 4.29; p=0.030). Conclusions: Endometrial cancer patients should be diagnosed earlier to reduce the risk of mortality. The public should be given education on the signs and symptoms of the disease.
Background: Breast cancer is the most prevalent malignancy among women with wide differences in clinical profile from region to region. The present study aimed to describe the profile of breast cancer patients attending a tertiary care hospital in Marathwada region of Western India. Materials and Methods: In this descriptive retrospective study, we reviewed records of pathologically diagnosed patients of breast cancer managed at our center from years 2009 to 2015. Data with respect to demographic status, detailed past, medical, familial and personal history, findings of clinical examination and histological features were obtained. Patients were staged according to the Tumor Node Metastasis (TNM) system. Results: Among 260 cases, mean age of presentation was 52.6, with average age of menarche of 11.3 and menopause of 52.6 years. The majority of patients were from urban regions and were postmenopausal (64.3%). Main clinical features presentation were breast lumps. Most patients were in stage II and had infiltrating duct carcinomas. Conclusions: Most common risk factors for breast cancer observed are increasing age, low parity and obesity. Breast cancer was more prevalent among postmenopausal women presenting in stage II with infiltating duct carcinoma in our region of India.
