  • 대장암은 결장과 직장에 생기는 약성의 종양을 말하며, 암이 발생하는 위치에 따라 결장에 생기는 암을 결장암, 직장에 생기는 암을 직장암이라고 하고, 이를 통칭하여 대장암 혹은 결장직장암이라고 한다. 대장암의 대부분은 대장의 점막에서 발생하는 선암이다. 선암의 대부분은 선종이라는 양성 종양(폴립, 용종)이 진행되어 발생하며 선암 이외에도 림프종, 육종, 편평상피암, 유암종 등이 발견된다.

  • 본 논문에서는 FDG-PET 영상을 사용하는 딥러닝 네트워크를 이용하여 직장암 환자의 치료 후 완치를 예측하는 연구를 수행하였다. 직장암은 흔한 악성 종양 중 하나이지만 병리학적으로 완전하게 치료되는 가능성이 매우 낮아, 치료 후의 반응을 예측하고 적절한 치료 방법을 선택하는 것이 중요하다. 따라서 본 연구에서는 FDG-PET 영상에 합성곱 신경망(CNN)모델을 활용하여 딥러닝 네트워크를 구축하고 직장암 환자의 치료반응을 예측하는 연구를 진행하였다. 116명의 직장암 환자의 FDG-PET 영상을 획득하였다. 대상군은 2cm 이상의 종양 크기를 가지는 환자를 대상으로 하였으며 치료 후 완치된 환자는 21명이었다. FDG-PET 영상은 전신 영역과 종양 영역으로 나누어 평가하였다. 딥러닝 네트워크는 2차원 및 3차원 영상입력에 대한 CNN 모델로 구성되었다. 학습된 CNN 모델을 사용하여 직장암의 치료 후 완치를 예측하는 성능을 평가하였다. 학습 결과에서 평균 정확도와 정밀도는 각각 0.854와 0.905로 나타났으며, 모든 CNN 모델과 영상 영역에 따른 성능을 보였다. 테스트 결과에서는 3차원 CNN 모델과 종양 영역만을 이용한 네트워크에서 정확도가 높게 평가됨을 확인하였다. 본 연구에서는 CNN 모델의 입력 영상에 따른 차이와 영상 영역에 따른 딥러닝 네트워크의 성능을 평가하였으며 딥러닝 네트워크 모델을 통해 직장암 치료반응을 예측하고 적절한 치료 방향 결정에 도움이 될 것으로 기대한다.

  • The purpose of this study is to understand the sex life of men with rectal cancer. Participants were 8 males who were treated with rectal cancer and analyzed semi-structured questionnaire by Downe-Wamboldt's content analysis method(Step 8). As a result of the analysis, three categories and nine subcategories were derived: Physical difficulty, Psychological difficulty, Mutual role difficulty. Thus, men treated with rectal cancer experience physical, psychological, and interrelated difficulties related to sex. This study was meaningful in that it revealed the experience related to sexual experience of men with rectal cancer and could be used as useful data for the development of sex - related programs.

  • Objectives : The purpose of this study was to investigate the needs for return-to-work support of cancer survivors and related factors in patients with cancer and their caregivers. Methods : 182 patients and 114 caregivers were recruited. Distress Thermometer and Problem List and scale ranging 0~10 measuring the degree of needs for return-to-work support were utilized. The needs for return-to-work support between the patient group and caregiver group (patient's needs evaluated by the caregiver) were compared, and related factors were investigated using logistic regression analysis. Results : 34.6% and 28.1% of patients and caregivers reported return-to-work support of cancer survivors is "very necessary". The degree of needs was 6.60±3.365 points in the patient group and 6.17±3.454 points in the caregiver group, with no significant difference (p=0.282). The needs for return-to-work support evaluated by patients was high when they underwent surgery (OR=2.592, p=0.007), has fertility problems (OR=6.137, p=0.025), has appearance problems (OR=2.081, p=0.041), or has fatigue (OR=2.330, p=0.020). The needs for return-to-work support of patients evaluated by caregivers was high when patients treated with breast cancer (vs respiratory cancer, OR=13.038, p=0.022 ; vs leukemia/lymphoma, OR=4.517, p=0.025 ; vs other cancer, OR=13.102, p=0.019), has work/school problems (OR=4.578, p=0.005), or has depression (OR=3.213, p=0.022). Conclusions : The degree of needs for return-to-work support of cancer survivors was high, and factors related to the needs were different between the two groups. This suggests that return-to-work support of cancer survivors is required, and clinical characteristics, the distress of patients, and differences between patients and their caregivers should be considered in establishing a support plan.

  • 본 연구는 직장암 검진에 영향을 미치는 요인을 규명하기 위해 시도하였다. 자료수집은 2011년 1월 10일부터 2월 23일까지 서울에 소재한 건강검진센터에 내원한 환자 211명을 대상으로 설문 및 면접조사를 하였다. 연구결과 첫째, 성별의 경우 남성 수검자는 74.2%로 비수검자 31.6%보다 유의하게 높은 분포를 보였다((p=0.035). 둘째, 흡연여부는 흡연자가 수검하는 경우는 47.4%, 비수검자는 25.4%로 두군간의 유의한 차이를 보였다(p=0.006). 셋째, 가족력이 있는 경우가 가족력이 없는 경우에 비해 교차비가 1.95로 유의하게 나타났다(95% Cl=1.69-3.41). 이러한 결과를 토대로 직장암 검진을 위한 적극적인 홍보를 위한 장-단기적인 전략을 세우는 것이 직장암 조기발견을 위한 효율적인 정책이라고 할 수 있겠다.

  • Bowel and rectal diseases are on the increase by irregular life and westernized eating habits of modern people, especially rectal cancer, which accounts for 50% of the entire colon cancer. For the initial rectal cancer, because there is no portion projecting on the surface, if not see inside the tissue with ultrasound, you make an errors that misdiagnosis as rectal abscess. However there is a need for more accurate diagnosis, because it is sometimes difficult to distinguish abscess from rectal cancer depending on staging, in spite of the ultrasonic diagnosis. Therefore, this study was performed quantitative analysis by using a computer algorithm for rectal cancer and abscess image. Each of 20 cases about normal, abscess and cancer by setting analysis region ($50{\times}50$ pixels) applies to GLCM algorithm and Autocorrelation, Max probability, Sum average, Sum variance in each image were analyzed by comparing the 4 single parameter. Consequently, The high lesion detection efficiency was presented 100% by the 3 parameter of Autocorrelation, Max probability, Sum variance and the parameter of Sum average presents 95% in cancer, more than 90% in abscess. Those parameters are valuable in distinction standard about normal, cancer and abscess in rectum. It is sufficient availability as a computer assisted diagnosis system depended on clinical using.
