Abstract
BACKGROUND In breast cancer patients receiving neoadjuvant chemotherapy (NAC), immediate breast reconstruction (IBR) as a breast cancer treatment option remains controversial. We assessed the impact of NAC on surgical and oncological outcomes of patients undergoing IBR. METHODS This was a retrospective multicenter study of 4726 breast cancer cases undergoing IBR. The rate of postoperative complications and survival data were compared between IBR patients who received NAC and those who did not receive NAC. Propensity score matching analysis was performed to mitigate selection bias for survival. RESULTS Of the total 4726 cases, 473 (10.0%) received NAC. Out of the cases with NAC, 96 (20.3%) experienced postoperative complications, while 744 cases (17.5%) without NAC had postoperative complications. NAC did not significant increase the risk of complications after IBR (Odds ratio, 0.96; 95%CI 0.74-1.25). At the median follow-up time of 76.5 months, 36 patients in the NAC group and 147 patients in the control group developed local recurrences. The 5-year local recurrence-free survival rate was 93.1% in the NAC group and 97.1% in the control group. (P < 0.001). After matching, there was no significant difference between the two groups. CONCLUSION IBR after NAC is a safe procedure with an acceptable postoperative complication profile.

Abstract
INTRODUCTION Involved surgical margins are risk factors for local recurrence and re-excision is often difficult, particularly in patients with breast cancer undergoing immediate breast reconstruction (IBR). However, the magnitude of the effect of radiation therapy on preventing local recurrence for breast cancers with involved margins has not been sufficiently assessed. MATERIALS AND METHODS We retrospectively assessed sites of involved surgical margins and local recurrence after mastectomy with IBR in patients with early breast cancer between 2008 and 2016. The effect of postoperative radiation therapy was evaluated in patients with involved margins, adjusted for nuclear grade, lymphatic invasion, surgical procedures, and primary systemic therapy. RESULTS A total of 274 (5.8 %) out of 4726 patients who underwent mastectomy with IBR had involved surgical margins: 133, 68, 88, and 26 had involvement of the skin, deep margin, lateral margins, and nipple, respectively (including duplicates). Radiation therapy was administered to 54 patients with involved margins. In patients with involved margins, 7-year cumulative incidences of local recurrence were 1.9 % and 12.6 % with and without radiation therapy, respectively (adjusted hazard ratio, 0.17; 95 % CI, 0.04-0.80). Local recurrence occurred in 28 patients, and the sites were skin, subcutaneous tissue, muscle, and nipple-areola complex in 7, 17, 1, and 3 patients, respectively. Among them, 23 (82.1 %) were associated with involved margin sites. CONCLUSIONS Radiation therapy meaningfully reduced the incidence of local recurrence in patients with breast cancer with margin involvement after mastectomy with IBR. Most local recurrences occurred at involved margin-related sites.

Abstract
BACKGROUND Position of the nipple-areolar complex (NAC) is an important factor in the esthetic impression of the breast, and NAC malposition is often an issue in breast reconstruction after nipple-sparing mastectomy (NSM). The purpose of this study was to evaluate the degree of NAC malposition depending on several factors using data quantified with the Mamma Balance application (Medic Engineering K.K., Kyoto, Japan). METHODS Patients who underwent unilateral breast reconstruction after NSM at eight hospitals in Japan between 2007 and 2020 were retrospectively investigated. Using Mamma Balance, NAC malposition was quantified separately in horizontal and vertical directions using patient photographs from pre-operatively and 6-24 months post-operatively. The degree of malpositioning was then statistically compared using various factors. RESULTS The NAC deviated more cranially and medially with implants than that with flaps. Cases with latissimus dorsi flap showed lateral malposition more often than cases with deep inferior epigastric artery perforator flap. With flaps, lateral incisions showed more lateral malposition, and peri-areolar incisions tended to show more medial NAC malposition. In cases with severe post-operative infection of the implant, the NAC tended to deviate cranially. In radiation cases, the NAC deviated cranially. No significant difference was observed according to the degree of breast ptosis or use of the pull-down operation. Only a very weak correlation was observed between a larger amount of mastectomy and more cranial NAC malposition with both flaps and implants. CONCLUSIONS This study provides insights into the tendencies and characteristics of NAC malposition.

Abstract
BACKGROUND The number of breast cancer patients in Japan undergoing immediate breast reconstruction (IBR) has increased and the postoperative follow-up period has been extended. This study was conducted to clarify the clinical aspects of, and factors associated with, local recurrence (LR) after IBR. METHODS This was a multicenter study which included 4153 early breast cancer patients who underwent IBR. Clinicopathological characteristics were examined and factors potentially contributing to LR were analyzed. Risk factors for LR were examined separately for non-invasive and invasive breast cancers. RESULTS The median follow-up period was 75 months. The 7-year LR rates were 2.1% and 4.3% for non-invasive and invasive cancers, respectively (p < 0.001). The proportions of LR detected by palpation, subjective symptoms, and ultrasonography were 40.0%, 27.3%, and 25.9%, respectively. Overall, 75.7% of LR were solitary, and 92.7% of these cases had no further recurrences during the observational period. Multivariate analysis of LR for invasive cancer showed that skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM), the presence of lymphovascular invasion, cancer at the surgical margin, and not receiving radiation therapy were factors related to LR. The 7-year overall survival rates of the patients with LR and non-LR of invasive cancers were 92.5% and 97.3%, respectively, (p = 0.002). CONCLUSIONS The rate of LR after IBR was acceptably low and IBR can thus be performed safely for early breast cancer patients. Invasive cancer, SSM/NSM, lymphovascular invasion, and/or cancer at the surgical margin should prompt awareness of the possibility of LR.

Abstract
Abstract
Purpose: Currently, CDK4/6i combined with endocrine therapy (ET) has become the standard of care as first- or second-line treatment for estrogen receptor-positive (ER+) human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC). However, at present, there are no guidelines for the selection of appropriate treatments after disease progression on prior CDK4/6i treatment combined with ET. Therefore, this retrospective study aimed to verify the efficacy and evaluate predictive factors of clinical outcomes in the patients with ER+/HER2- MBC during subsequent-abemaciclib treatment after disease progression on prior-palbociclib combined with ET.
Methods: In total, 81 patients with ER+/HER2- MBC were treated with palbociclib and ET at our medical center between December 2017 and November 2020. Among them, 25 patients who received subsequent-abemaciclib after disease progression on prior-palbociclib were included. All patients provided informed consent for the indicated treatment. Clinicopathological variables were compared using Fisher’s exact test. The Mann–Whitney U test was used to compare categorical variables. PFS and time to chemotherapy (TTC) were estimated using Kaplan–Meier analysis with 95%CIs.
Results: The median age was 69 years, and four women were premenopausal. Stage IV disease occurred in 28.0% (7/25) and visceral metastases were observed in 68.0% (17/25) of the patients. The treatment line of prior-palbociclib was the first-line in 3 (12.0%), second-line in 11 (44.0%), and third- and late-line in 11 patients (44.0%). The median PFS of prior-palbociclib plus ET was 6.3 months (95%CI=5.814–6.786). Subsequent-abemaciclib combined with fulvestrant after disease progression on prior-palbociclib was administered in 64.0% (16/25) of the patients. Median numbers of previous ET and chemotherapy of subsequent-abemaciclib were 2 and 0, respectively. Subsequent-abemaciclib after disease progression on prior-palbociclib resulted in an ORR and clinical benefit rate (CBR) of 16.0% (4/25) and 44.0% (11/25), respectively (Table 1). Kaplan–Meier curve analysis showed that the median PFS was 5.3 months (95%CI=3.082–7.518). Univariate analysis revealed that the best overall response (BOR) ≥PR and progression-free interval (PFI) ≥6 months in prior-palbociclib contributed to better clinical outcomes. Moreover, in multivariate analysis, BOR to prior-palbociclib was the only independent predictive factor for PFS (HR=0.190; 95%CI=0.050–0.722; p=0.015) (Table 2). With regard to grade ≥3 TRAEs in the subsequent-abemaciclib, neutropenia and diarrhea were observed in 16.0% (4/25); appetite loss and fatigue in 12.0% (3/25); leukopenia and anemia in 8.0% (2/25); and thrombocytopenia and liver dysfunction in 4.0% (1/25) of patients. Twelve patients (48.0%) required dose reduction due to TRAEs grade ≥3 in subsequent-abemaciclib. Of them, 10 patients required one dose-level reduction and 2 needed two dose-level reductions. Three patients (12.0%) required dose discontinuation: two had uncontrollable appetite loss and nausea and one had pneumonia. Of the 25 patients, 12 were not administered any prior chemotherapy and the median TTC in those treated with subsequent-abemaciclib was 33.9 months (95%CI=11.334–56.136). Next-line treatment after disease progression on subsequent-abemaciclib in the patients who were not administered prior chemotherapy was performed in 2 (8.0%) who were treated with ET and in 12 (48.0%) who were treated with chemotherapy (1 taxane-based, 7 eribulin, and 4 oral 5-fluorouracil). The median PFS in patients treated with chemotherapy after disease progression on subsequent-abemaciclib treatment was 6.2 months (95%CI=3.484–8.916).

Abstract
BACKGROUND Little information is available about the clinical and pathologic characteristics of local recurrence (LR) after nipple-sparing mastectomy according to the locations of LR. METHODS This study classified 99 patients into the following two groups according to the location of LR after nipple-sparing mastectomy: nipple-areolar recurrence (NAR) group and other locations of LR (oLR) group. The study evaluated whether the location of LR was associated with disease-free survival (DFS) after LR resection. RESULTS For about half of the patients (44.4 %) with NAR, the primary cancer was estrogen receptor (ER)-negative and human epidermal growth factor receptor 2 (HER2)-positive. Conversely, in most of the patients with oLR (79.2 %), the primary cancer was ER-positive and HER2-negative. Among the LR tumors, the frequency of noninvasive carcinoma in the NAR tumors was significantly higher than in the oLR tumors (51.9 % vs 4.2 %, respectively). During a median follow-up period of 46 months, the location of LR was not associated with DFS after LR. In the NAR group, the presence or absence of LR tumor invasiveness was the only factor associated with DFS. In the oLR group, age at primary surgery was the only factor associated with DFS. CONCLUSION This multi-institutional retrospective study demonstrated that the features of NAR, such as the characteristics of the primary and recurrent tumors and the prognostic factors after LR resection, were quite different from those of oLR.

Abstract
Background and Purpose In breast cancer patients receiving neoadjuvant chemotherapy (NAC), the use of immediate breast reconstruction (IBR) as a breast cancer treatment option remains controversial. The Japanese breast cancer society conducted retrospective multicenter cohort study in the era of IBR, and we assessed the impact of NAC on surgical and oncological outcomes in patients underwent IBR. Methods Between January 2008 and December 2016, 473 (10.0%) breast cancer cases received NAC of 4726 cases underwent IBR after mastectomy. The clinicopathological and survival data of patients who received NAC (the NAC group) and those who did not receive NAC (the control group) were compared in terms of postoperative complications (infection, hemorrhage, seroma, dehiscence, tissue expander or implant loss, flap or skin necrosis) and oncologic safety. Results Eight-hundred forty cases had minor or major complications. NAC did not increase the risk of complications after IBR (OR 1.20; 95%CI 0.95 - 1.53; p = 0.13). Smoking (OR 1.35; 95%CI 1.14 - 1.62; p = 0.001), overweight (BMI25≤) (OR 1.94; 95%CI 1.61 - 2.35; p < 0.001), PMRT (OR 1.54; 95%CI 1.20 - 1.99; p = 0.01) increased risk of complications. At the median follow-up time of 76.5 months, 36 patient (7.6%) in the NAC group and 147 patients (3.5%) in the control group had local recurrence. 35 patient (7.4%) in the NAC group and 147 patients (2.0%) in the control group had reginal recurrence. Conclusion Immediate breast reconstruction after NAC is a safe procedure with post-operative complication profile. It can be performed safely and therefore should be considered as a strategy preferred for patients with local advanced breast cancer.

Abstract
BACKGROUND One barrier to the widespread use of breast reconstruction (BR) is physicians' perception that BR adversely affects breast cancer prognosis. However, there is limited information regarding physicians' understanding of the impact of BR on patient prognosis and which physicians have misunderstandings about BR. METHODS We conducted an e-mail survey regarding the impact of BR on the prognosis of patients with breast cancer among members of the Japanese Breast Cancer Society. RESULTS Of 369 respondents, 99 (27%) said that they believe BR affects patient prognosis. Female respondents and those who treat fewer new breast cancer patients per year were more likely to state that they believe BR affects patient prognosis (P = 0.006 and 0.007). Respondents who believed that BR affects patient prognosis underestimated 5-year overall survival rates in patients who receive BR and subsequently have local or regional recurrence in different sites. CONCLUSION Our survey demonstrated that a quarter of respondents believe that BR affects patient prognosis and underestimate survival rates in patients who receive BR and have subsequent local or regional recurrence. Because of the lack of evidence regarding the impact of BR on patient prognosis, educating physicians by providing accurate knowledge regarding BR and patient prognosis is highly recommended.

Abstract
Butter is an emulsion of water in oil containing approximately 25% unsaturated fat. It is
used in various types of cooking because of its delectable flavour. However, oxygen
absorption by the unsaturated fatty acids alters its quality. Therefore, oxidation
measurement is essential for the quality evaluation of butter. Although titrimetric analysis
is mainly used for oxidation measurement in butter, it needs a large quantity of samples
and reagents, and the results lack reproducibility. In this study, the colourimetric method
was evaluated to measure oxidation levels in butter. A comparative analysis of the
standard titrimetric methods and the colourimetric method revealed an increase in the
oxidation levels with an increase in time. The findings demonstrated a positive correlation
between the titrimetric and colourimetric methods. Furthermore, the measurement
accuracy of the colourimetric method was less than 10% (1.7–9.5%) on all examination
days. Overall, these findings suggest the efficiency of the colourimetric method to
measure oxidation in butter with increased accuracy.

Abstract
The rate of metastasis to the central nervous system is high in human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer patients. Metastatic cauda equina tumors are characterized by rapid progression of symptoms, thus signifying the requirement of their early treatment. However, these tumors are rarely reported, and their optimal treatment options have not been established yet. Here, we report a case study of a patient with HER2-positive breast cancer that metastasized to the cauda equina. The patient underwent urgent surgery to relieve the spinal cord compression. The pain in her back and lower limbs was greatly reduced. Unfortunately, her ability to walk did not improve sufficiently. Overall, surgical treatment may be a favorable option to improve a patient's quality of life.

Abstract
Abstract
Purpose
We aimed to explore the association of blood pressure (BP) classification using the 2017 American College of Cardiology/ American Heart Association Guideline and the prevalence of hypertensive retinopathy using a nationwide epidemiological database.
Methods
This study is a retrospective observational cross-sectional analysis using the health claims database of the JMDC between 2005 and 2020. We analyzed 280,599 participants who did not take anti-hypertensive medications. Each participant was categorized as having normal BP (systolic BP [SBP] <120 mm Hg and diastolic BP [DBP] <80 mm Hg; n=159,524); elevated BP (SBP 120–129 mm Hg and DBP <80 mm Hg; n=35,603); stage 1 hypertension (SBP 130–139 mm Hg or DBP 80–89 mm Hg; n=54,795); or stage 2 hypertension (SBP ≥140 mm Hg or DBP ≥90 mm Hg; n=30,677). Retinal photography at health check-up was classified as normal, grade 1, grade 2, grade 3, or grade 4 according to the Keith-Wagener-Barker system.
Results
Median (interquartile range) age was 46 (40–53) years, and 50.4% were men. Hypertensive retinopathy which was defined as ≥ Keith-Wagener-Barker system grade 1, was observed in 16,836 participants (6.0%). Multivariable logistic regression analysis showed that, compared with normal BP, elevated BP (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.23–1.38), stage 1 hypertension (OR 1.71, 95% CI 1.64–1.79), and stage 2 hypertension (OR 4.10, 95% CI 3.93–4.28) were associated with higher prevalence of hypertensive retinopathy. Even among 92,121 participants without obesity, high waist circumference, diabetes mellitus, dyslipidemia, cigarette smoking, and alcohol drinking, multivariable logistic regression analysis showed that, compared with normal BP, elevated BP (odds ratio 1.34, 95% CI 1.19–1.51), stage 1 hypertension (OR 1.79, 95% CI 1.61–1.98), and stage 2 hypertension (OR 4.42, 95% CI 4.00–4.92) were associated with higher prevalence of hypertensive retinopathy. The association between BP category and hypertensive retinopathy was observed in all subgroups stratified by age or sex.
Conclusion
Our investigation showed that the prevalence of hypertensive retinopathy increased with the blood pressure category, suggesting that atherosclerotic change could start even in elevated BP and stage 1 hypertension.

Abstract
BACKGROUND The efficacy and safety of nanoparticle albumin-bound (nab)-paclitaxel combined with S-1 in patients with operable breast cancer is uncertain. We evaluated the feasibility of this combination followed by epirubicin/cyclophosphamide (EC) as neoadjuvant chemotherapy in such patients. PATIENTS AND METHODS This was an open-label, single-arm, phase II, single-institution prospective study of 4 cycles of nab-paclitaxel (260 mg/m2) administered intravenously on day 1 in combination with S-1 (65 mg/m2 orally twice daily) on days 1 to 14 every 21 days followed by EC as neoadjuvant chemotherapy. RESULTS Of 30 patients, 1 required a dose interruption for nab-paclitaxel combined with S-1; 4 required a dose reduction for nab-paclitaxel, 1 for S-1, and 4 for EC. Mean relative dose intensities of nab-paclitaxel, S-1, and EC were 98.0%, 99.3%, and 98.2%, respectively. Overall clinical response rate was 96.7%. In histological response, grade 3, pathological complete response (pCR; ypT0/is and ypN0) rate was 63.3% and grade 2b (near pCR) was 3.3%. pCR was observed in 57.1% of luminal B human epidermal growth factor receptor type 2 (HER2)-negative patients, 55.6% of luminal B HER2-positive patients, 100% of HER2-positive patients, and 57.1% of triple-negative breast cancer patients. Grade 3/4 neutropenia was observed in 1 patient during nab-paclitaxel combined with S-1 and in 7 during EC treatments. The most frequent nonhematological severe adverse events were grade 3 peripheral neuropathy in 2 patients and grade 3 arthralgia in 2 patients during nab-paclitaxel combined with S-1. CONCLUSION Tri-weekly nab-paclitaxel with S-1 followed by EC is effective and well tolerated as neoadjuvant chemotherapy in patients with operable breast cancer.

Abstract
Abstract
Background: Targeting the molecular components of the cell cycle to interfere with cell cycle progression is a logical strategy for cancer treatment. Cyclin-dependent kinase (CDK) 4 and 6 promote cell cycle progression. Palbociclib is a selective inhibitor of CDK4 and CDK6 that obstructs progression from the G1 phase to the S phase and inhibits subsequent DNA synthesis. Palbociclib has been approved as a novel molecular targeting drug for hormone receptor-positive/HER2- advanced or metastatic breast cancer (MBC) combined with endocrine therapy. In a phase 3 trial, palbociclib-fulvestrant (PF) significantly improved progression-free survival (PFS) of patients with ER+/HER2- advanced or MBC. However, in Japanese patients, did not improve in the PF group. Moreover, neutropenia was higher in Japanese patients. We conducted a retrospective study to verify the efficacy and safety of PF in Japanese patients. Methods: Thirty-nine ER+/HER2- advanced or MBC patients treated with fulvestrant (F) alone and 31 patients treated with PF at the Saitama Medical Center from July 2012 to November 2018 were included. Fulvestrant 500 mg was administered intramuscularly on days 1 and 15 of cycle 1, and then every 28 days thereafter starting from day 1 of cycle 1. Palbociclib 125 mg/day was administered orally on days 1 to 21, followed by 7 days off treatment for every 28-day cycle. Premenopausal and perimenopausal women were also treated with LHRH agonist subcutaneously. Results: In the F and PF groups, the complete response were 0% and 3.2%, respectively, the partial response were 2.6% and 38.7%, respectively, and the rates of long stable disease were 20.5% and 22.6%, respectively. Therefore, the objective response rate in the F and PF groups were 2.6% and 41.9% (P < 0.001), respectively, and the clinical benefit rate (CBR) were 23.1% and 61.3% (P = 0.002), respectively. We observed significant differences in the CBR in patients with the following characteristics: age <70 years (F: 16.7% vs PF: 63.2%; P = 0.002), BMI ≥25 (F: 10% vs PF: 69.2%; P = 0.001), ≤1 previous endocrine therapy (F: 21.1% vs PF: 60%; P = 0.001), ≤1 previous chemotherapy (F: 21.1% vs PF: 61.5%; P = 0.002), no sensitivity to prior endocrine therapy (F: 22.5% vs PF: 60%; P = 0.0049), stage I-III at initial diagnosis (F: 23.3% vs PF: 59.1%; P = 0.011), DFI ≥24 months (F: 30% vs PF: 69.2%; P = 0.038), two or more metastatic sites (F: 21.7% vs PF: 65%; P = 0.006), and visceral metastasis (F: 22.7% vs PF: 73.3%; P = 0.006). The median PFS was significantly improved in the PF (PF vs F: 13.3 months vs 3.9 months, HR, 0.272, 95% CI, 0.128-0.574, p < 0.001). The most common adverse events reported for the PF group were leukopenia, neutropenia, anemia, and fatigue. Hematologic adverse events were more frequent in the PF group than in the F group. There was also no febrile neutropenia in either group. The most common nonhematologic adverse events were fatigue (41.9% in PF vs 5.2% in F). Fever without neutropenia occurred in two patients in the PF group. The only higher than Grade 3 nonhematologic adverse event was liver dysfunction (5.1%), which occurred in the F group. There were no serious adverse events, such as embolism, in either group. There was no dose discontinuation of palbociclib due to adverse events; however, 58.1% (18/31) of patients required dose interruption and 71% (18/31) required dose reduction due to Grade 3 or 4 neutropenia. Sixteen of 31 (51.6%) patients required one dose-level reduction and 6 of 31 (19.4%) required two dose-level reductions. The median number of courses for the first dose reduction was 2 (range: 1-5), and the median for the second dose reduction was 3 (range: 2-5). Conclusion: PF was tolerable and significantly improved clinical outcome in Japanese patients with ER+/HER2- MBC.

Abstract
PURPOSE Periareolar incisions for nipple-sparing mastectomy offer the advantages of smaller inconspicuous wounds and easier resection below the nipple-areolar complex. However, they provide a narrow surgical field, which complicates the procedure and carries a risk of nipple necrosis. This study evaluated the clinical outcomes and safety of periareolar incisions for breast reconstructive surgery in patients with breast cancer. METHODS The study included 181 patients with primary operable breast cancer who underwent nipple-sparing mastectomy for reconstructive breast procedures without intraoperative nipple-areolar complex resection. The clinical outcomes and complications were retrospectively evaluated. The recurrence-free survival was compared using Kaplan-Meier curves. RESULTS Nipple-sparing mastectomy was performed via inframammary fold and periareolar incisions in 31 and 150 patients, respectively. There were no significant differences in clinical outcomes related to surgery, frequency of complications, nipple necrosis (inframammary fold incision vs. periareolar incision: 0% vs. 3.3%, P = 0.590), or the recurrence-free survival (P = 0.860) between the 2 groups. CONCLUSION Our results showed that the clinical outcomes and complication rates of periareolar incisions for breast reconstruction were equivalent to those of inframammary fold incisions, suggesting that the periareolar incision technique for breast reconstructive surgery may safely improve cosmetic outcomes if done with adequate care.

Abstract
BACKGROUND/AIM Published data have shown that palbociclib-fulvestrant can significantly improve the progression-free survival (PFS) of estrogen receptor-positive/human epidermal growth factor receptor 2-negative (ER+/HER2-) metastatic breast cancer patients, but not of Japanese patients. We conducted this retrospective study to verify the efficacy and safety of palbociclib-fulvestrant in Japanese patients. PATIENTS AND METHODS ER+/HER2- metastatic breast cancer patients treated with fulvestrant (n=39) or palbociclib-fulvestrant (n=31) at the Saitama Medical Center from July 2012 to November 2018 were evaluated. RESULTS Overall response rates (ORRs) were 2.6% (fulvestrant) and 41.9% (palbociclib-fulvestrant) (p<0.001), and clinical benefit rates (CBRs) were 23.1% and 61.3% (p=0.002), respectively. The palbociclib-fulvestrant group had significantly higher CBR and PFS (hazard ratio(HR):0.272, 95% confidence interval(95CI):0.128-0.574 for PFS). Grade 3/4 neutropenia occurred in 80.6% of the palbociclib-fulvestrant group, while febrile neutropenia was not detected. CONCLUSION Japanese ER+/HER2- metastatic breast cancer patients tolerated palbociclib-fulvestrant, with significantly improved clinical outcomes.

Abstract
Background: While Preservation of NAC is concerned to increase the risk of local recurrences in the retroareolar glandular tissue, nipple sparing mastectomy (NSM) is increasing in patients with breast cancer and has been shown to result in better cosmetic outcome and the benefit for quality-of-life. It is necessary to predict accurately NAC involvement in order to select which patients may be candidates to NSM. The distance from the nipple to the tumor (DNT) is proposed as one of the best criteria to select the patient. The purpose of this study is to identify the predictors of NAC involvement retrospectively and to develop a clinical predictive model to select the patients who can be offered preservation of NAC.Methods: A total of 168 patients with primary operable breast cancer who received subcutaneous mastectomy for breast reconstruction at Saitama Medical Center during July 2013 to December 2017 were selected from the hospital's surgical database. NAC involvement was defined by the presence of invasive carcinoma and/or ductal carcinoma in situ at the subareolar margin.
Results: Of the 148 patients who were preserved NAC, 89.9% (133/148) were NAC involvement negative and 10.1% (15/148) were positive in permanent pathological specimens. Of the 20 patients who were resected NAC, NAC involvement positivity was only 50.0% (10/20). This revealed that NAC involvement with a sensitivity (SN) of 40.0%, a specificity (SP) of 93.0%, a positive predictive value (PPV) of 50.0% and a negative predictive value (NPV) of 89.9% (AUC=0.665, 95%CI: 0.5345-0.796). In 140 patients who were performed intraoperative sub-nipple frozen section biopsy, the findings was significantly associated with NAC involvement (P<0.001), and which predict the NAC involvement with a SN of 93.3%, a SP of 89.6%, a PPV of 51.9%, and a NPV of 99.1% (AUC=0.915, 95%CI: 0.835-0.994). In the concordance rate between frozen section findings and definitive pathologic results, DCIS was 53% (9/17), atypical cell was 50% (2/4) and invasive ductal carcinoma was 100% (3/3). Correlation between NAC involvement and clinicopathological factors, tumor size ≥4cm (P<0.001), DNT <1cm by MMG (P=0.002), DNT <1cm by MRI (P<0.001), nipple contrast findings by MRI (P<0.001), tumor in central portion (P<0.001), multicentirc/focal lesion (P<0.001), c(N) positive (P=0.014) were significant relation with NAC involvement. Each predictors were scored 0 or 1, and the total score of 0-3 points was defined as low risk, 4 points as intermediate risk, and 5-7 points as high risk. Depending on this categorized classification, the NAC involvement rate was 3.5% (5/142) in low risk, 68.7% (11/16) in intermediate risk, 90.0% (9/10) in high risk and there was a significant correlation between the risk group and NAC involvement (P <0.001). Notably, assuming that NAC is preserved for low risk patients and is resected for intermediate and high risk patients, NACPI contributes to improve the accuracy of selecting the surgical procedures (SN 80.0%, SP 95.8%, PPV 76.9%, NPV 96.5% (AUC=0.879, 95%CI: 0.784-0.974)).Conclusion: This study suggests that NACPI can help us indicating subcutaneous mastectomy for the breast cancer patients who request preserve NAC with more oncological safety.

Abstract
A 48-year-old woman had a left breast mass identified during routine breast cancer screening. The mammogram showed pleomorphic-segmental microcalcifications in the mediolateral-oblique view of the left breast. Ultrasonography showed a hypoechoic mass approximately 3.7 cm in diameter with multiple calcifications. Contrast-enhanced magnetic resonance imaging of the breast showed non-mass like enhancement of approximately 4 cm in diameter in the C area of the left breast. She was diagnosed with glycogen-rich clear cell carcinoma (GRCC) by ultrasound-guided vacuum-assisted biopsy. Nipplesparing mastectomy was performed along with sentinel lymph node biopsy. The intraoperative consultation suggested sentinel lymph node metastasis and we therefore performed axillary lymph node dissection. Pathological examination reported microinvasive carcinomas, 0.4 cm in maximum diameter, and extensive intraductal components, 5 cm in size. The tumor cells were stained on PAS staining, but the stains were digested with diastase. The cells were negative for adipophilin. GRCC was first reported by Hull et al. This is a rare type of breast carcinoma. There is no standard therapy for this disease or any data on the prognosis of breast cancer patients with GRCC.

Abstract
BACKGROUND In this randomized controlled trial, we examined whether intra- and postoperative infusion of low-dose ketamine decreased postoperative morphine requirement and morphine-related adverse effects as nausea and vomiting after scoliosis surgery. METHODS After IRB approval and informed consent, 36 patients, aged 10-19 years, undergoing posterior correction surgery for adolescent idiopathic scoliosis, were randomly allocated into two groups: intra- and postoperative ketamine infusion at a rate of 2 μg/kg/min until 48 h after surgery (ketamine group, n = 17) or infusion of an equal volume of saline (placebo group, n = 19). All patients were administered total intravenous anesthesia with propofol and remifentanil during surgery and intravenous morphine using a patient-controlled analgesia device after surgery. The primary outcome was cumulative morphine consumption in the initial 48 h after surgery. Pain scores (Numerical Rating Scale, NRS, 0-10), sedation scales, incidence of postoperative nausea and vomiting (PONV), and antiemetic consumption were recorded by nurses blinded to the study protocol for 48 h after surgery. RESULTS Patient characteristics did not differ between the two groups. Cumulative morphine consumption for 48 h after surgery was significantly lower in the ketamine group compared to the placebo group (0.89 ± 0.08 mg/kg vs. 1.16 ± 0.07 mg/kg, 95% confidence interval for difference between the means, 0.03-0.48 mg/kg, P = 0.019). NRS pain, sedation scales, and incidence of PONV did not differ between the two groups. Antiemetic consumption was significantly smaller in ketamine group. CONCLUSIONS Intra- and postoperative infusion of low-dose ketamine reduced cumulative morphine consumption and antiemetic requirement for 48 h after surgery.

Abstract
138 Background: Nanoparticle albumin-bound paclitaxel (nab-PTX) has a high transitivity into tumor tissue compared to solvent-based paclitaxel (sb-PTX). In a phase III study in patients with metastatic breast cancer, nab–PTX demonstrated nearly double the response rate and significantly longer time to tumor progression than paclitaxel. However, the current problems are that nab-PTX is a higher rate of discontinuation and sensory neuropathy than sb-PTX. We sought to evaluate the efficacy and safety of nab-PTX followed by FEC. Methods: In this study, patients were received 4 cycles of nab-PTX (80 mg/m2) q1w (days 1, 8, and 15 of each 4-week cycle) followed by 4 cycles of FEC q3w. The primary endpoint was pCR rate (ypT0/is ypN0). The secondary endpoints included clinical response rate, disease-free survival, breast-conserving surgery rate, and safety. Results: Forty patients were enrolled; the median age was 53 (range 33-81), postmenopausal women were 62.5%. ER positivity, PgR positivity and HER2 positivity were 62.5%, 52.5% and 37.5%, respectively. Clinical stage for I, II and III were 30%, 62.5% and 7.5%, respectively. The pCR rate (ypT0/is ypN0) was 40% (16/40). In the subtype subset, pCR rates were Luminal A 20% (1/5), Luminal B (HER2 negative) 15.4% (2/13), Luminal B (HER2 positive) 60% (6/10), HER2 enrich 80% (4/5) and TNBC 42.9% (3/7). The breast-conserving surgery rate was 77.5% (31/40). The clinical response rates were cCR 20.0% (8/40), cPR 52.5% (21/40), cSD 25% (10/40) and cPD 2.5% (1/40) after 4 cycles of nab-PTX, cCR 32.5% (13/40), cPR 42.5% (17/40), cSD 20% (8/40) and cPD 5% (2/40) after nab-PTX followed by FEC. Ninety-eight percent patients completed 4 cycles of planned protocol dose of nab-PTX and 62.5% completed FEC. The Grade3/4 hematologic toxicity of nab-PTX was only neutropenia 2.5%. Grade1/2 non-hematologic toxicity were neuropathy 12.5%, arthralgia 7.5% and myalgia 7.5%. Grade3/4 non-hematologic toxicity was no reported. Conclusions: This is the first study to evaluate weekly nab-PTX (80 mg/m2) followed by FEC for operable breast cancer. Our results demonstrated that weekly nab-PTX (80 mg/m2) followed by FEC was well-tolerated and resulted in increased pCR rate than reported data of nab-PTX. Clinical trial information: UMIN000011048.

Abstract
Acute lung injury (ALI) is a severe illness with excess mortality and no specific therapy. Protective actions were recently uncovered for docosahexaenoic acid-derived mediators, including D-series resolvins. Here, we used a murine self-limited model of hydrochloric acid-induced ALI to determine the effects of aspirin-triggered resolvin D1 (AT-RvD1; 7S,8R,17R-trihydroxy-4Z,9E,11E,13Z,15E,19Z-docosahexaenoic acid) on mucosal injury. RvD1 and its receptor ALX/FPR2 were identified in murine lung after ALI. AT-RvD1 (~0.5-5 μg kg(-1)) decreased peak inflammation, including bronchoalveolar lavage fluid (BALF) neutrophils by ~75%. Animals treated with AT-RvD1 had improved epithelial and endothelial barrier integrity and decreased airway resistance concomitant with increased BALF epinephrine levels. AT-RvD1 inhibited neutrophil-platelet heterotypic interactions by downregulating both P-selectin and its ligand CD24. AT-RvD1 also significantly decreased levels of BALF pro-inflammatory cytokines, including interleukin (IL)-1β, IL-6, Kupffer cells, and tumor necrosis factor-α, and decreased nuclear factor-κB-phosphorylated p65 nuclear translocation. Taken together, these findings indicate that AT-RvD1 displays potent mucosal protection and promotes catabasis after ALI.

Abstract
132 Background: S-1, an oral fluoropyrimidine formulation that combines tegafur, 5-chloro-2,4-dihydroxypryidine, and potassium oxonate in a molar ratio of 1:0.4:1 has been widely used against solid cancers including gastric, colorectal, pancreatic, lung and breast cancer. In a phase II study, the response rate (RR) was 41.7% and the median survival was 872 days among taxane-pretreated patients with metastatic breast cancer (MBC). However, the predictive factor of S-1 in patients with MBC has not been determined yet. The purpose of this study is to investigate the correlation between 5-FU-related enzyme and clinical efficacy of S-1 in patients with MBC. Methods: Forty-eight patients with MBC were treated with S-1 twice daily at a dose of 80 mg/m2 for 4 weeks, followed by a 2-week rest interval. Laser-captured microdissection was performed from the formalin-fixed, paraffin-embedded tumor sections at surgery and the expression of 5-FU-related enzyme including thymidylate synthase (TS), thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) was evaluated by RT-PCR. Results: The median age was 58 years. ER, PgR, HER2 was positive in 57, 28, and 14% of the entire patients, respectively. The median number of pretreated chemotherapy regimens was 2 (range 0-6). The sites of metastatic disease were the viceral in 25 patients, bone in 9 patients and soft tissue in 17 patients. The overall response rate (RR) was 22.9% (11/48) and clinical benefit rate was 41.7% (20/48). The median time to tumor progresssion (TTP) was 14.3 months (range 6.0 – 22.7). ER, PgR and HER2 status was not significantly correlated with RR. TS expression was significantly associated with clinical efficacy of S-1. Moreover, it is notable that triple negative breast cancer (TNBC) revealed lower TS expression than luminal type (TNBC vs luminal type = 80% (8/10) vs 36.4% (4/11), P= 0.054, OR 0.143, 95% CI 0.020-1.032). According to the correlation between metastatic sites and RR, better RR was noted for soft tissue metastases (soft tissue vs visceral = 25% (5/20) vs 84% (5/6), OR 15.0 (95%CI 1.40–161.05). Conclusions: This study demonstrated that TS is a significant predicitve factor of S-1 in patients with MBC.

Abstract
Hepatic hydrothorax is defined as the presence of a significant pleural effusion that develops in a patient with cirrhosis of the liver who does not have an underlying cardiac or pulmonary disease. There have been few published case reports dealing with hepatic hydrothorax treated surgically. Recently, we treated a patient with refractory hepatic hydrothorax by directly suturing the diaphragmatic defect during VATS. During surgery, the diaphragmatic defect was identified by using abdominal insufflation with CO(2) . The defect was sutured and the diaphragm was covered by polyglycolic acid felt and fibrin glue. After surgery, the patient's pleural effusion improved, his postoperative course was uneventful and he did not require a drainage tube at discharge.

Abstract
BACKGROUND Studies have suggested that HOXB9 expression in breast cancer cells promotes cellular invasiveness, metastatic ability, and tumor neovascularization in the surrounding tissue in in vitro and in vivo assays. These findings imply that HOXB9 overexpression may alter tumor-specific cell fates and the tumor stromal microenvironment, contributing to breast cancer progression. The objective of this study was to analyze whether these results could be applied to clinical practice. METHODS A total of 141 consecutive, invasive ductal carcinoma patients who underwent surgical treatment were examined. Immunohistochemical staining was performed to evaluate the expression of HOXB9, Ki-67, CD31, and CD34, and the association of tumor proliferation and angiogenesis with HOXB9 expression was analyzed. RESULTS Of the 141 tumor specimens immunostained for HOXB9, 69 (48.9%) stained positive. Larger primary tumor size, hormone receptor negativity, HER2 positivity, higher nuclear grade, and number of pathologic nodal metastases were significant variables associated with HOXB9 expression. Notably, 12 (92.3%) of 13 triple-negative breast cancer cases showed HOXB9 expression. Disease-free survival and overall survival were significantly different between the HOXB9-positive and HOXB9-negative groups (hazard ratio 20.714, P = 0.001; and hazard ratio 9.206, P = 0.003, respectively). Multivariate analysis indicated that HOXB9 expression was the only independent prognostic factor for disease-free survival (hazard ratio 15.532, P = 0.009). HOXB9-positive tumors showed a significant increase in the number of vasculature and the Ki-67 ratio compared with HOXB9-negative tumors. CONCLUSIONS HOXB9 expression, which promotes tumor proliferation and angiogenesis, is a significant prognostic factor in breast cancer.

Abstract
Low level, antenatal exposure to dioxins is associated with low birth weight, which in turn is associated with long-term sequelae. We exposed the human extravillous cytotrophoblast (EVT) lines HTR-8/SV40 and TCL1 to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and assessed cell growth, invasion, and differentiation. TCDD had no effect on cell proliferation, invasion, or tube formation in Matrigel. The EVT-derived cells expressed a functional aryl hydrocarbon receptor protein; however, TCDD exposure did not alter expression levels of proteins involved in EVT differentiation in early pregnancy, including hypoxia-inducible factor 1A (HIF1A), vascular endothelial growth factor (VEGF), Integrin A1, A6, and AVB3. These results suggest that the reduction in fetal weight induced by dioxin is not the result of vascular remodeling via EVT dysfunction.

Abstract
33 Background: We demonstrated that HOXB9, a member of homeobox genes, expression promoted tumor neovascularization and metastasis in vitro and in vivo assay. These findings imply that overexpression of HOXB9 contributes to tumor progression through activation of signaling pathways that alter both tumor-specific cell fates and tumor-stromal microenvironment, leading to increased invasion and metastasis. (Hayashida et al., PNAS 2010) We sought to determine whether these results could be extended to the clinical application. In this study, we evaluated the correlation between HOXB9 expression, clinical outcomes, and the clinicopathological variables in breast cancer patients, and the contribution of HOXB9 expression to tumor cell proliferation and angiogenesis. Methods: A consecutive series of 141 patients with invasive ductal carcinoma who underwent surgical treatment were examined. HOXB9 protein expression was analyzed immunohistochemically using the anti-human HOXB9 polyclonal antibody. Immunostaining of Ki-67, CD31, and CD34 were performed to evaluate the association of proliferation and tumor angiogenesis with HOXB9 expression. Results: Of 141 tumor specimens immunostained for HOXB9, 69 specimens (48.9%) were positive staining. Univariate logistic regression revealed ER and PgR negativity, HER2 positivity, high nuclear grade, and large pathological tumor size as significant variables associated with HOXB9 expression. Moreover, 12 (92.3%) out of 13 triple negative breast cancer showed HOXB9 expression. The disease-free survival (DFS) and the overall survival were significantly different between the HOXB9 positive and negative group; HR=20.714, p=0.001, HR 9.206, p=0.003, respectively. A Multivariate analysis indicated that HOXB9 expression was the only independent prognostic factor for DFS (HR=15.532, p=0.009). In subgroup analysis, HOXB9 positive tumors showed a significant increase in the number of vasculature and the Ki-67 ratio in comparison with HOXB9 negative. Conclusions: Our results suggest that HOXB9 expression promoting the tumor proliferation and the angiogenesis is a significant prognostic factor in breast cancer.

Abstract
Abstract
Background: There are several reports showing a HOX gene family, which plays the critical roles for the differentiation during the embryonic stage, is associated with the tumorigenicity. It was demonstrated that HOXB9 is overexpressed in 42% of breast cancers, specifically those with high histological grade, and it defined the functional consequences of elevated HOXB9 expression in breast cancer. Moreover, HOXB9 expression promotes increased neovascularization and tumor metastasis to the lung in mouse xenograft models (Hayashida et al., PNAS, 2010). The purpose of this research is to evaluate the correlation between HOXB9 expression and poor prognosis in breast cancer patients.
Patients and methods: A consecutive series of 141 patients with invasive ductal carcinoma who underwent surgical treatment at Keio University Hospital from January 2004 to January 2005 was involved. HOXB9 expression was analyzed immunohistochemically on formalin-fixed, paraffin-embedded tumor sections using rabbit anti-human HOXB9 polyclonal antibody.
Results: The age at the diagnosis ranged from 30 to 93 years (median age, 58 years), and median observation period was 62.2 months. Of 141 tumor specimens immunostained for HOXB9, 69 specimens (48.9%) were positive staining. Univariate logistic regression revealed ER negativity (p<0.001), PR negativity (p<0.001), HER2 positivity (p=0.031), high nuclear grade (p<0.001) and large pathological tumor size (p=0.002) as significant variables associated with HOXB9 expression. The disease-free survival (DFS) at 5 year was significantly different between the HOXB9 positive group and HOXB9 negative group (HR=8.5, 95%CI 3.3-21.9, p=0.001). A Multivariate analysis indicated that HOXB9 expression was the independent prognostic factor for DFS (Table 1). Number of the patients with lung metastasis was significantly larger in HOXB9 positive patients. Conclusion: These data show that HOXB9 expression can be a new independent prognostic factor in breast cancer.

Abstract
ABSTRACTWe recently demonstrated that C60 and C70, as well as other fullerenes, can be deposited and accumulated on surfaces using laser ablation of graphite in an Inert gas atmosphere. After learning of the work of Krätschmer et al. indicating the presence of C60 in carbon soot, we showed that samples consisting almost exclusively of C60 and C70 can be sublimed from such soot. Vibrational Raman spectra of C60 and C70 were obtained from these samples. The C60 spectrum Is consistent with the calculated spectrum of Buckmlnsterfullerene, and the strongest three lines can be assigned on the basis of frequency and polarization. The NMR spectrum of dissolved C60 was then obtained, and found to consist of a single resonance, establishing the icosahedral symmetry of this molecule. STM images of the C60 molecules on a Au(111) crystal face show that these clusters form hexagonal arrays with an intercluster spacing of 11.0 Å and are mobile at ambient temperature. Distinctly taller species evident in the arrays are believed to be C70 clusters. Vibrational Raman and infrared spectra have also been obtained for separated C60 and C70.

Abstract
Abstract
Background: Doxorubicin containing combination chemotherapy regimens are widely used for treatment of breast and other cancers. However, these regimens are associated with significant toxicities including myocardialdysfunction and alopecia. Analogues of doxorubicin are being developed to reduce these side effects. Pirarubicin is a more lipophilic derivative of doxorubicin, with a higher uptake rate of cells, lower cardiotoxicity and better antitumor efficacy in preclinical models.
Purpose: We conducted a single-institution phase I clinical trial to determine the maximum-tolerated dose (MTD) and define the toxic effects and recommended dose (RD) of pirarubicin in combination with cyclophosphamide in patients with breast cancer. Patients and Methods: Patients who had received prior anthracycline therapy were excluded. Cohorts of three patients with breast cancer were treated with escalating doses of pirarubicin (40 to 70 mg/m2) intravenously administered every three weeks in combination with cyclophosphamide (60 mg/m2) for 4 or more cycles.
Results: Eleven patients of stage I/II operable breast cancer received a total of 46 cycles of pirarubicin and cyclophosphamide as post-operative adjuvant chemotherapy. The most frequently reported treatment-related grade 2 adverse events were constipation (36%) and nausea (27%). There were no grade 3/4 events. Grade 2 leukocytopenia and grade 2 fatigue were dose-limiting at 70 mg/m2, the maximum-tolerated dose was 60 mg/m2. Grade 2 alopecia was reported in 60 and 70 mg/m2 pirarubicin group. Conclusion: At the MTD of 60 mg/m2 every 3 weeks, pirarubicin in combination with cyclophosphamide was associated with mild, reversible toxicity. The recommended phase II dose is pirarubicin 50 mg/m2 and cyclophosphamide 60 mg/m2 on day 1 every 21 days.

The disease-free survival (DFS) at 5 year and the overall survival at 5 year were significantly different between the HOXB9 positive group and HOXB9 negative group; HR=8.5, 95%CI 3.3-21.9, p=0.001, HR 3.8, 95%CI 1.5-9.6, p=0.003, respectively. A Multivariate analysis indicated that HOXB9 expression was the independent prognostic factor for DFS (HR=14.1, 95% CI 1.851 to 107.4, p=0.011). Since HOXB9 expression accelerates the tumor angiogenesis in vitro and in vivo, we also evaluated the expression of vascular endothelial marker, CD31 and CD34 and cellular proliferation marker, Ki-67 in 45 patients with clinical T2 (tumor size, 2 to 5cm) tumor. In this subgroup analysis, HOXB9 positive patients (n=22) showed increased number of vasculature and Ki-67 ratio in comparison with HOXB9 negative patients (n=23) with statistical significance.
Correlations between HOXB 9 expression and Ki-67, CD31 and CD 34
Conclusion: The data identify HOXB9 expression as a new independent prognostic factor in breast cancer, which might help to improve the selection for appropriate therapy. Possibly, it might be useful to determine the application of anti-angiogenic therapy.

Abstract
The biomass of microorganisms in the digestive tracts of young salmon in the sea of Saanich Inlet was examined by (i) the direct microscopic method, (ii) the plate count method and (iii) the physiological method (microbial biomass assumed from the release of carbon dioxide). By all methods, most microbial biomass in foods was shown to decrease during its stay in the digestive organ. This observation was supported by the detection of many bacteria at different stages of digestion. The microbial biomass was quantitatively influenced by the composition of food ingested and by the sampling time.

Abstract
Microbial biomass on suspended organic matter in seawater of the euphotic zone of Saanich Inlet was investigated. The viable microorganisms were measured by the glucose-uptake method. Microbial carbon on particulate organic matter in seawater was determined to be, on the average, 9.9 mug of C/liter, and there was a regression relationship as y = 0.0062 x - 1.79 with an unbiased variance V(yx) = 0.38, where x = particulate organic carbon in seawater (micrograms of C/liter) and y = logarithm of microbial carbon (micrograms of C/liter).

Abstract
The post-operative changes in the serum levels of CRP and serum amyloid A (SAA) were investigated prospectively in 106 patients after posterior lumbar interbody fusion. In 96 patients who did not have complications related to infection within the first year after operation, the median levels of CRP before operation and on days 3, 7 and 13 after were 0.02 (0.01 to 0.03), 9.12 (2.36 to 19.82), 1.64 (0.19 to 6.10) and 0.53 (0.05 to 2.94) mg/dl, respectively and for SAA, 2.6 (2.0 to 3.8), 1312.1 (58.0 to 3579.8), 77.3 (1.8 to 478.4), 14.1 (0.5 to 71.9) μg/ml, respectively. The levels on day 3 were the highest for both CRP and SAA and significantly decreased (p < 0.01) by day 7 and day 13. In regard to CRP, no patient had less than the reference level (0.1 mg/dl) on day 7. In only three had the level decreased to the reference level, while in 93 it was above this on day 13. However, for SAA, the levels became normal on day 7 in 10 cases and on day 13 in 34 cases. The ratios relative to the levels on day 3 were significantly lower for SAA compared with CRP on day 7 and day 13. Of the ten patients with infection in the early stages, the level of CRP decreased slightly but an increase in SAA was observed in six. We concluded that SAA is better than CRP as a post-operative inflammatory marker.
