Primary care physicians' perceptions concerning engagement in cancer survivor care
Background: Given the growing diversity among cancer survivors and the fact that oncologists typically do not perform long-term care, the expected role of primary care physicians (PCPs) in survivor care is expanding. However, communication and collaboration between oncologists and PCPs are lacking. Therefore, we assessed the perception of cancer survivor care among PCPs. Methods: We sent a questionnaire to 767 Japanese Board-certified PCPs, regardless of facility type (clinics and hospitals), inquiring about PCPs' perceptions of their role in survivor care. Additionally, we included vignette-based scenarios focused on colorectal and prostate cancer survivors to explore factors associated with their clinical decisions. Results: We obtained 91 replies (response rate: 11.9%). A total of 75% of PCPs had encountered at least 1 cancer patient in actual practice. Even for patients actively receiving cancer treatment, >70% of PCPs reported that they were willing to engage in comprehensive survivor care, except for the administration of anticancer drugs. Further, 49% of PCPs considered that both PCPs and oncologists were suited to performing regular screening for cancer recurrence in high-risk patients. Multivariable logistic regression analyses revealed that clinic PCPs were less inclined to conduct screening for recurrence than hospital PCPs in both colorectal (odds ratio, 3.85 [95% confidence interval 1.40-10.6]) and prostate (4.36 [95% confidence interval 1.51-12.6]) cancer scenarios. Conclusions: Our findings suggest that Japanese PCPs are willing to engage in survivor care and encourage closer collaboration between oncologists and PCPs. However, oncologists might need to request cooperation, considering the facility type with which PCPs are affiliated
Therapeutic effect of neuraminidase-treated LAK cells on liver metastasis of Colon 26.
To improve the lymphokine-activated killer (LAK) cell therapy for liver metastasis, two methods which enhance accumulation of LAK cells in the liver were examined for their effects on the liver metastasis of Colon 26 cancer cells in BALB/c mice. Distribution of LAK cells in the mice was examined by the 51Cr labeling method. Portal vein infusion of LAK cells or tail vein infusion of neuraminidase treated-LAK (N-LAK) cells showed an augmented accumulation of infused cells in the liver. In the first experiment, LAK cells (5 x 10(7) cells) were infused in the portal vein or tail vein at days 3 and 7 after the inoculation of 5 x 10(4) tumor cells and 1 x 10(4) units of IL-2 were given three times a day from day 3 to day 7. The portal infusion of LAK cells produced a greater reduction of liver metastases compared with the peripheral infusion. In the second experiment, 5 x 10(7) LAK cells or N-LAK cells were infused via the tail vein on days 1 and 3, and 1 x 10(4) units of IL-2 were given once a day from day 1 to day 5 after the inoculation of 1 x 10(4) tumor cells. The therapeutic effect of N-LAK cells was greater than non-treated LAK cells on the number of metastatic lesions and the survival time of mice. Since access to the human portal vein is difficult and risky in clinical situation, peripheral infusion of N-LAK cells is preferable.</p
A Case of Colonic Metastasis of Breast Cancer Positive for Estrogen Receptor
This is the first report of a metastatic colon cancer of breast cancer positive for estrogen receptor. A 56-year-old woman who had undergone standard radical mastectomy due to right breast cancer was suffered from left lower abdominal pain. Barium enema and proctoscopy revealed a narrowing at the rectum and the descending colon. Needle biopsy of the rectum revealed Group 5. The resection of the left colon, the rectum and the ovaries were performed. Foci were macroscopically present at the rectum, the sigmoid colon and the descending colon. Histological examination revealed that colonic foci were metastases from the breast cancer of lobular carcinoma. The colonic preparation was positive for estrogen receptor

Decline in the Functional Status and Mortality in Patients on Hemodialysis: Results from the Japan Dialysis Outcome and Practice Patterns Study
ObjectivesPatients with end-stage renal disease (ESRD) treated with hemodialysis suffer a high burden of poor functional status. Poor functional status is known as a strong, consistent predictor of mortality. However, little is known about the trajectory of functional status and its association with clinical outcomes in the ESRD population. We examined the association between a change in the functional status over time and all-cause mortality among patients on hemodialysis.Design and methodsThis was a prospective cohort study of 817 patients with ESRD on hemodialysis with repeat measures of functional status, who enrolled in the Japan Dialysis Outcomes and Practice Patterns Study phase V. The functional status was assessed based on the Katz Index and Lawton-Brody instrumental activities of daily living scale, and the assessments were conducted twice over a median of 361 (range: 339-378) days between 2012 and 2013. We classified patients into 2 groups based on having or not having at least a 1-point decline in the functional status score. To evaluate the association between the decline in the functional status and all-cause mortality with adjustment for potential confounders, a Cox regression analysis was conducted.ResultsOver the study period, 19.9% of the patients showed a decline in the functional status score. During the follow-up period, 44 (5.4%) patients died. Using the Cox regression analysis and adjusting for potential confounders, it was determined that the decline in functional status score was significantly associated with higher mortality (incidence rate: 2.2 vs. 7.0 per 100 person-years; adjusted hazard ratio: 2.68; 95% confidence interval: 1.31-5.50).ConclusionsThe present study provides evidence that ESRD patients on hemodialysis demonstrating a decline in the functional status are at elevated risk of mortality. Our findings strengthen the evidence underpinning the importance of interventions to maintain the functional status in this vulnerable population
