Purpose: Bone is one of the most common sites of metastases in patients with advanced lung cancer. Skeletal complications may cause significant morbidity and decrease performance status (PS). Such complications, referred to as skeletal related events (SREs), include severe bone pain, pathological fractures, spinal cord compression, and hypercalcemia of malignancy. We assessed the clinical impact of SREs in non-small lung cancer (NSCLC) patients with bone metastases. Methods: We retrospectively investigated the clinical records of all 120 patients who were diagnosed advanced NSCLC with bone metastases between June 1998 and March 2009. Results: A total of 23 patients (26.7%) were found to have SREs at the time of initial diagnosis. The median survival time (MST) was 123 days for patients with SREs, while it increased to 276 days for those without SREs. The MST of the patients with SREs were significantly shorter than that of the patients without SREs (p<0.001). We also studied the SREs during clinical courses of 89 patients whose records were available over 3 months. A total of 39 patients (43.8%) were found to have SREs during clinical courses. Conclusion: The patients in NSCLC with bone metastases were often found to have SREs. SREs cause significant morbidity and deterioration of PS. Systemic chemotherapy could not decrease SREs during their clinical courses. Further studies evaluating bisphosphonates in combination with chemotherapy are warranted.

We tried to evaluate the right ventricular function using a modified Swan-Ganz catheter with a rapid responsive thermistor. Twenty-four dogs comprised this series. Twelve were the model of left heart failure (Group A), and the other twelve were the model of right heart failure (Group B) produced by multiple ligation of coronary arteries. Dogs were studied for some of the circulatory indices before and after ligation with left atrial pressure at 10, 15 and 20mmHg in group A, and right atrial pressure at 10, 15 and 20mmHg in group B by volume loading. In group A, when the left atrial pressure was kept constant, right ventricular ejection fraction (RVEF) and right ventricular stroke work index (RVSWI) were decreased significantly after the ligation of coronary arteries. But there was no significant change in the peak right ventricular pressure-right ventricular endsystolic volume index ratio (peak RVP/RVESVI) associated with ligation. In group B, significant changes were observed in RVEF, RVSWI and peak RVP/RVESVI. Thus, it was found that right ventricular contractility in selective left heart failure was not reduced. E_max was considered to be a valuable index of ventricular contractility not affected by preload and afterload of ventricle, but this index is not easily measured clinically. The index peak RVP/RVESVI which is nearly equivalent to E_max, has an advantage in that it can be determined by the thermodilution method widely used in general. We conclude that this index is very useful to us for post-operative care in cardiac surgery.

Recently, arterial keton body ratio (AKBR) has attracted attention as a new indicator of liver function which is in equibilium with the ratio between oxidized and reduced forms of free nicotinamide-adenine dinucleotides (free NAD⁺/NADH ration) in the mitochondria. There are few reports on whether AKBR contributes to the hepatic energy charge in the open heart surgery with extra corporeal circulation (ECC) or not. This study was undertaken to clarify the contribution of AKBR to the hepatic energy charge during ECC and the relationship between AKBR and hepatic blood flow. AKBR was determined before, during and after ECC in the open heart surgery for 14 patients. Furthermore, the blood flow in hepatic artery, portal vein and liver microcirculation was measured before, during and after ECC in canine models. Finally, the pulsatile perfusion was performed in canine models and compared with the conventional non-pulsatile perfusion for the blood flow and AKBR. In clinical cases, AKBR was decreased in all cases during the ECC. AKBR which was measured at 2 or 3hr after weaning from the ECC was negatively correlated to the total perfusion time with -0.57 as the correlation coefficient. Six patients who were on the ECC over 180min did not show a good recovery of the AKBR after weaning from the ECC. Especially, three patients presented a clinical picture of acute hepatic failure with jaundice, elevation of the serum levels of transaminase and direct hyperbililubinemia, but only one showed hypoglycemia. These patients showed no improvement in clinical data and AKBR. The patient with improved AKBR recovered clinically. In our experiment, the blood flow in the hepatic artery, portal vein was measured by electromagnetic blood flow meter and the liver microcirculation was measured by laserdoppler flowmeter. The blood flow was decreased remakably in the non-pulsatile group at all sites of measurement: it recovered after ECC in hepatic artery and portal vein, but liver microcirculation did not improve well. AKBR was decreased during ECC and did not recover after ECC in the non-pulsatile perfusion. When the pulsatile perfusion was performed, liver circulation was maintained well, and AKBR recovered well after ECC. The above results suggest that AKBR reflects the liver microcirculation and pulsatile perfusion is beneficial to the liver microcirculation. Pulsatile circulation, however, involves several problems, hemolysis, the decrease of platelets, and so on, but these problems have been improved gradually. We think that the pulsatile perfusion will be used in clinical operations to maintain the good hepatic circulation.

Objective: The benefits of combining cancer screenings with clinical surveys have become increasingly obvious as cancer morbidity and mortality have steadily increased. This paper discusses a study on the current status of and issues surrounding breast cancer screening in a clinical survey. The study also investigated the patients' awareness of the benefits of breast cancer screening. A secondary aim of the study was to promote mammographic screening.;Subjects and Methods: During the 72 months between April 1999 and March 2005, a total of 36,505 women underwent clinical surveys in our hospital. In October 2002, mammographic examination was included as an optional part of the routine physical examination. We evaluated the results of breast cancer screening with or without mammographic examination and used a questionnaire to investigate the patients' awareness of the benefits of breast cancer screening.;Results: Compared with the pre-2001 results, the detection rate of breast cancer significantly increased after 2003 when physical examination was combined with mammographic examination. Our study also found that both elderly patients and those residing in the suburbs of Sapporo City tended to choose physical examination alone rather than combining it with mammographic examination. An analysis of the questionnaires collected from these patients indicates they had a poor understanding of and lacked awareness of the benefits of mammographic examinations during breast cancer screenings.;Conclusions: The inclusion of mammographic screenings with clinical surveys was found to be significantly useful in the detection of breast cancer. Further continued education is needed for women, particularly the elderly and residents in the suburbs, so they understand the benefits of breast cancer screening by mammographic examination for the early detection of breast cancer and, consequently, decreased mortality of the disease.

This study aimed to ascertain the current status of Japanese sperm banking for young cancer patients. During 2015, we mailed the directors of 695 institutes where sperm cryopreservation might be performed with questionnaires requesting information on the number of patients, age, precryopreservation chemotherapy, semen analyses results and diagnoses, cryopreservation success rate, and causes of unsuccessful cryopreservation. Of these 695 institutes, 92 had cryopreserved sperm before chemotherapy within the study period. In all, 820 cancer patients (237 testicular, 383 hematological, 46 bone and soft tissue, 20 brain, and 134 other malignancy) consulted the responding institutes for sperm cryopreservation. Except for testicular tumor, the number of patients whose sperm was preserved before cancer treatment was low compared to that of young cancer patients. Approximately 20% of patients with malignancies other than testicular tumor underwent chemotherapy before cryopreservation. The success rate of cryopreservation in hematological malignancy was 82.5%, significantly lower than that of both the testicular cancer (93.6%) and other malignancy groups (95.6%) (P < 0.05). The primary reasons for preservation failure were azoospermia and poor semen quality. Patients with hematological malignancies had a higher rate of unsuccessful cryopreservation compared to those in other groups, possibly due to the large number of patients requesting sperm cryopreservation after chemotherapy induction. In Japan, information regarding sperm banking prior to cancer treatment appears to be lacking. Information regarding sperm preservation before chemotherapy should be provided to all Japanese oncologists.
