  • We tested how adjuvants effect in a cancer vaccine model using an epitope derived from an autoactivation loop of membrane-type protease serine protease 14 (PRSS14; loop metavaccine) in mouse mammary tumor virus (MMTV)-polyoma middle tumor-antigen (PyMT) system and in 2 other orthotopic mouse systems. Earlier, we reported that loop metavaccine effectively prevented progression and metastasis regardless of adjuvant types and TH types of hosts in tail-vein injection systems. However, the loop metavaccine with Freund's complete adjuvant (CFA) reduced cancer progression and metastasis while that with alum, to our surprise, were adversely affected in 3 tumor bearing mouse models. The amounts of loop peptide specific antibodies inversely correlated with tumor burden and metastasis, meanwhile both TH1 and TH2 isotypes were present regardless of host type and adjuvant. Tumor infiltrating myeloid cells such as eosinophil, monocyte, and neutrophil were asymmetrically distributed among 2 adjuvant groups with loop metavaccine. Systemic expression profiling using the lymph nodes of the differentially immunized MMTV-PyMT mouse revealed that adjuvant types, as well as loop metavaccine can change the immune signatures. Specifically, loop metavaccine itself induces TH2 and TH17 responses but reduces TH1 and Treg responses regardless of adjuvant type, whereas CFA but not alum increased follicular TH response. Among the myeloid signatures, eosinophil was most distinct between CFA and alum. Survival analysis of breast cancer patients showed that eosinophil chemokines can be useful prognostic factors in PRSS14 positive patients. Based on these observations, we concluded that multiple immune parameters are to be considered when applying a vaccine strategy to cancer patients.

  • The matrix metalloproteases (MMPs) play important roles in invasion, metastasis and angiogenesis in various cell types. Tissue inhibitor of metalloprotease (TIMP)-2, an endogenopus inhibitor of MMP-2, has been shown to inhibit invasion and metastasis. We have previously shown that MMP-2 is responsible for the H-ras-induced invasive and migrative phenotypes in MCF10A human breast epithelial cells. Here, we investigated the effect of TlMP-2 overexpression on invasion and migration in H-ras MCF10A cells. (omitted)

  • An endobronchial metastasis is defined as a subsegmental or a more proximal central bronchial metastasis of a nonpulmonary neoplasm in the bronchoscopically visible range. However, the frequencies of endobronchial metastasis range from 2 to 50% of pulmonary metastases from extrathoracic neoplasms by a different definition of an endobronchial metastasis. Primary neoplasms of an endobronchial metastasis including breast cancer, colon cancer, renal cell carcinoma, and ovarian cancer are relatively common. However, an endobronchial metastasis arising from thyroid cancer, parotid gland tumor, bone tumor, bladder cancer, and stomach cancer has only rarely been reported in the literature. Here we report a case of an endobrochial metastases from a hepatocellular carcinoma.

  • 기저막 성분인 type IV collagen을 분해하는 type IV collagenase의 농도와 종양의 전이사이에 상관관계가 있다는 동물 실험보고가 있다. 저자들은 유방암환자의 종양조직내 type IV collagenase의 농도와 골스캔상 골전이 소견과 비교하여 그 의의를 알아보고자 하였다. 원발성 및 전이성 유방암 환자의 종양조직에서 92kDa 및 72kDa type IV collagenase에 대한 면역조직화학염색을 각각 57명, 56명 환자에서 시행하여 각 효소 농도를 평가하고 골스캔상 골전이 소견을 관찰하고 등급을 부여하였다. 면역조직화학적으로 평가한 각 효소의 농도는 원발성 유방암과 전이성 유방암 환자 사이에 큰 차이가 있었으며, 골스캔 소견과 효소농도를 상호 비교한 결과 각 효소의 농도가 170이하일 경우에는 골스캔상 활동적인 골전이 소견을 볼 수 없었으나 효소의 농도가 200이상일 경우 골스캔 소견은 정상에서 골전이 소견까지 매우 다양하게 분포하였다. 결론적으로, 면역 조직화학적으로 측정한 92kDa 및 72kDa collagenase의 농도가 170이하일 때는 골스캔상 대부분 정상소견을 보여 골전이의 확률이 낮았다. 반면에 각 효소치의 농도가 200이상일 경우에는 골전이의 확진과 병소의 위치를 확인하고 추적검사를 위해서는 골스캔이 필요하다고 사료된다.

  • Nurses play an important role in patient education, including providing patients with useful and appropriate information. The purpose of this study was to explore what particular types of information were important to women diagnosed with breast cancer. Sixty seven women with breast cancer an outpatient clinic in W Christian Hospital responded to the structured questionnaires developed by the investigator. Interviews and mail surveys were used in this study. The findings in this study showed that six kinds of information needs arose, ranked as the signs and symptoms of recurrence, the possibility of recurrence, the possibility of metastasis, treatment, diet and physical activities in daily living. Marital status, level of education, and level of monthly income were not related to level of informational need. Younger women rather than older women had a greater need to seek information(r=-.471, p<.01). There was a significantly negative relationship between duration of disease and the score on information needs(r=-.32, p<.05). The findings have implications that the opportunity to ask questions and have accurate information on the recurrence should be provided to women with breast cancer.

  • 목적 유방암 환자의 수술 전 자기공명영상에서 림프절 전이를 시사하는 소견들에 따른 진단 성적을 알아보고자 한다. 대상과 방법 수술 전 유방 자기공명영상을 촬영하고 유방암 수술을 시행한 192명의 환자를 후향적으로 분석하였다. 영상 소견에서 림프절의 크기와 장경/단경의 비율, 피질의 두께와 모양, 변연, 수질의 소실, 비대칭성, T2 강조영상에서의 신호강도, 이른 조영증강의 정도, 조영증강의 역학을 조사하였다. 수신자판단특성곡선 분석, 카이 분석과 t-검정, 맥니마 검정을 이용하여 통계분석을 시행하였다. 결과 단경의 증가, 피질의 불규칙한 모양과 피질 두께의 증가, 수질의 소실, 비대칭성, 피질의 불규칙한 변연 그리고 T2 강조영상에서의 낮은 신호강도는 전이를 시사하는 의미 있는 소견이었다. 이중 단경과 피질의 두께에 대해 수신자판단특성곡선 분석으로 각각 8.05 mm와 2.75 mm로 절단값을 얻었다. 2.75 mm 이상의 피질 두께, 피질의 불규칙한 모양은 맥니마 검정으로 다른 소견들과 비교할 때 민감도의 유의한 차이를 보였다. 피질의 불규칙한 변연(100%)은 가장 높은 특이도를 보였다. 결론 유방 자기공명영상의 전이 림프절 분석에서 2.75 mm 이상의 피질 두께와 피질의 불규칙한 모양은 다른 소견들보다 높은 민감도를 보이고 피질의 불규칙한 변연은 가장 높은 특이도를 보이는 소견이다.

  • 본 연구에서는 석류 유래 나노베지클이 유방암 세포인 MDA-MB-231 세포에 항 혈관 신생효과와 세포 증식을 억제하는지 확인하고자 하였다. 석류 주스로부터 분리한 석류 유래 나노베지클(PNVs)이 평균 직경이 162 nm의 이중막 구조인 나노베지클을 검증하였다. MDA-MB-231 세포에 석류 유래 나노베지클의 내재화를 확인하였다. 석류 유래 나노베지클이 MDA-MB-231 세포에 농도 의존적으로 세포 증식률을 감소시키는 것을 확인하였다. 또한, 석류 유래 나노베지클이 MDA-MB-231 세포에 침윤 및 전이를 억제하는 것을 확인하였다. 마지막으로 세포 발현 단백질을 증가시키고 MMP-2, MMP-9 단백질의 발현을 감소시키는 것을 검증하였다. 본 연구는 석류 유래 나노베지클이 인간 유방암 세포인 MDA-MB-231 세포의 세포 침윤 및 전이를 억제하고 세포사멸을 시켜 항암효과가 있음을 제시하고 있다. 따라서 석류 유래 나노베지클이 유방암 예방 및 치료에 이용 가능함으로 시사된다.

  • Because carcinoma of breast is known to readily metastasize to the bone, early detection of metastasis spread is very important. Two hundred thirty four consecutive patients who had $^{99m}Tc-MDP$ bone scans prior to treatment and during the follow up period were studied retrospectively to determine the contribution of the scans to staging, treatment and follow up examination between Jan. 1980 and Apr. 1987 in Seoul National University Hospital. 1) Positive bone scan rates in initial clinical stage I, II, III and IV were 0%, 4%, 14% and 53%, respectively. 2) The higher clinical stage is, the more cumulative risk of conversion to positive bone scan is during the same follow up period. 3) Conversion rate to positive bone scan in patients with lymph node metastasis is higher (50%) than those without metastasis (18%) (P < 0.001). We concluded that the bone scan in primary breast cancer was very useful to evaluate initial clinical stage and to perform the follow up examination.

  • Background: Ten to 30% of early breast cancer (EBC) patients develop brain metastasis (BM) during their follow-up. In this study, we aimed to evaluate importance of the lymph node ratio (LNR) in development of BM in EBC cases. Materials and Methods: Ninety patients whom had axillary metastases in lymph nodes at their initial diagnosis and developed BM during 5-year follow-up were detected in 950 EBC patients. LNR values were calculated for all patients and after categorization into 4 molecular sub-types as luminal A, luminal B HER-2 (+), HER-2 overexpressing and basal- like. Comparison was with control group patients who had similar characteristics. Results: In the comparison of all molecular sub-types of LNR, 54.9% and 28.4% values were found in patients with and without BM respectively (p<0.001). In the comparison of the LNR with control groups, a statistically significant differences were found with luminal A with BM (p=0.001), luminal B HER-2 (p=0.001), HER-2 overexpressing (p=0.027) and basal-like groups (p<0.001). In the evaluation of patients with BM, the highest ratio was found in the basal-like group (67.9%) and there was a statistically significant difference between this group and the others (p=0.048). Conclusions: EBC patients developing BM within 5 years follow-up had significantly higher LNRs for all molecular sub-types, especially in the basal-like group. Larger scale studies are now needed for evaluating LNR prognostic importance for EBC regarding BM development.
