RESUMO

BACKGROUND: Immediate volume replacement using a free dermal fat graft (FDFG) has been proven safe with early postoperative benefits. The aims of the present study were to clarify adequate indications and risk factors associated with operative morbidity. PATIENTS AND METHODS: A multi-institutional analysis of partial mastectomy with immediate volume replacement with FDFG was undertaken in 14 hospitals specializing in breast cancer treatment. Clinical and oncological variables were analyzed to identify factors associated with postoperative complications. RESULTS: A total of 262 cases were analyzed. Considering the observation period and overlap of patients, 13 (5.4%) out of 242 patients had complications within 1 month of surgery while 7 (4.6%) out of 151 patients developed complications 1-12 months after surgery. Two hundred and eleven out of 242 patients were statistically examined using a multivariate analysis, which revealed that the weight of resected breast tissue, size of implanted FDFG (cranio-caudal length), and weight of implanted FDFG were associated with a higher likelihood of postoperative complications. CONCLUSIONS: Immediate breast volume replacement using a FDFG after breast cancer surgery should be done for selected patients with breast cancer to avoid postoperative complications. The prospective and larger investigations are warranted for the establishment of appropriate guidelines.

RESUMO

BACKGROUND: We investigated the efficacy and safety of metronomic chemotherapy with combined irinotecan and tegafur-gimeracil-oteracil potassium (TS-1) in patients with metastatic and recurrent breast cancer (MRBC), and the association between irinotecan metabolizing enzyme UDP-glucuronosyltransferase 1A1 (UGT1A1) gene polymorphisms and adverse events. METHODS: The study group comprised 40 patients aged 35-79 years. Irinotecan (60 mg/m(2) in 5 % dextrose) was administered by 120-min infusion on days 1, 8, and 15 every 4 weeks. TS-1 (prescribed in a standard quantity) was administered at 80 mg/m(2)/day orally on days 3-7, 10-14, and 17-21 every 4 weeks. RESULTS: Tumor response data were available for 34 patients. Median follow-up was 12 months (range 1-45 months). Response rate was 47 % (one complete and 15 partial responses). Stable disease was observed in 17 patients (50 %). One patient had disease progression (3 %). Median progression-free survival was 14 months [95 % confidence interval (CI), 10-26]. Median overall survival was 26 months (95 % CI not calculable owing to sample size), and 79.3 % of patients survived for 1 year. The most common grade 3 or 4 adverse events were neutropenia (15 %), leukopenia (12.5 %), diarrhea (7.5 %), and anemia (2.5 %). All other adverse events were grade 1 or 2. Treatment-related toxicity was generally modest and manageable. No significant correlation was observed between UGT1A1 polymorphisms and hematological or non-hematological toxicities. CONCLUSIONS: Metronomic chemotherapy with combined irinotecan and TS-1 was effective in MRBC patients. Adverse effects were mild and the regimen was safely administered without identifying UGT1A1 polymorphisms.

RESUMO

We report the case of a 60-year-old male patient who was diagnosed with metastasis from primary lung cancer to the breast. The patient presented with a mass in the right breast. Mammography, ultrasound, and magnetic-resonance imaging each suggested primary breast cancer. A core-needle biopsy of the right breast mass indicated poorly differentiated adenocarcinoma. A basic chest X-ray showed a shadow in the left upper lung. Thoraco-abdominal computed tomography revealed a mass with a diameter of 90 mm in the left superior region, the shape of which was indicative of primary lung cancer. A lung biopsy confirmed poorly differentiated adenocarcinoma. We diagnosed primary lung cancer with metastases to the bone, brain and right breast (cT2N3M1, stage IV) by imaging and histopathology. He was administered carboplatin (area under the curve 6 mg / ml) and paclitaxel (200 mg / m(2)) tri-weekly, and underwent gamma-knife treatment for the brain metastasis. The treatments reduced the primary tumor and the metastases. However, after completion of the fifth treatment cycle, he developed disseminated intravascular coagulation from septic shock, and died on the eleventh day after completing the fifth cycle of treatment. Although metastasis to the mammary gland is uncommon, especially among males, metastasis to the mammary gland should be considered when a mammary mass does not exhibit the typical characteristics of breast cancer. A correct diagnosis of metastasis to the mammary gland from lung cancer makes it possible to select the most appropriate treatment method.

RESUMO

INTRODUCTION: Since treatment modalities for metastatic recurrent triple-negative breast cancer (mrTNBC) are limited, a novel treatment approach including immunotherapy is required. We have developed a novel regimen of personalized peptide vaccination (PPV), in which vaccine antigens are individually selected from a pool of different peptide candidates based on the pre-existing host immunity. Herein we conducted a phase II study of PPV for metastatic recurrent breast cancer patients to investigate the feasibility of PPV for mrTNBC. METHODS: Seventy-nine patients with metastatic recurrent breast cancer who had metastases and had failed standard chemotherapy and/or hormonal therapy were enrolled. They were subgrouped as the mrTNBC group (n = 18), the luminal/human epidermal growth factor receptor 2 (HER2)-negative group (n = 41) and the HER2-positive group (n = 18), while the remaining two patients had not been investigated. A maximum of four human leukocyte antigen (HLA)-matched peptides showing higher peptide-specific immunoglobulin G (IgG) responses in pre-vaccination plasma were selected from 31 pooled peptide candidates applicable for the four HLA-IA phenotypes (HLA-A2, -A24, or -A26 types, or HLA-A3 supertypes), and were subcutaneously administered weekly for 6 weeks and bi-weekly thereafter. Measurement of peptide-specific cytotoxic T lymphocyte (CTL) and IgG responses along with other laboratory analyses were conducted before and after vaccination. RESULTS: No severe adverse events associated with PPV were observed in any of the enrolled patients. Boosting of CTL and/or IgG responses was observed in most of the patients after vaccination, irrespective of the breast cancer subtypes. There were three complete response cases (1 mrTNBC and 2 luminal/HER2-negative types) and six partial response cases (1 mrTNBC and 5 luminal/HER2-negative types). The median progression-free survival time and median overall survival time of mrTNBC patients were 7.5 and 11.1 months, while those of luminal/HER2-negative patients were 12.2 and 26.5 months, and those of HER2-positive patients were 4.5 and 14.9 months, respectively. CONCLUSIONS: PPV could be feasible for mrTNBC patients because of the safety, immune responses, and possible clinical benefits.

RESUMO

PURPOSE: We compared the safety, invasiveness and cosmetic outcomes between endoscopic breast-conserving surgery (endoscopic group) and surgery under direct vision (direct vision group) for treating breast cancer. METHODS: We compared 100 cases of endoscopic surgery with 150 cases of direct vision surgery. The safety was evaluated in terms of the blood loss, length of the operation and presence or absence of complications, whereas the degree of invasiveness was assessed using preoperative and postoperative leukocyte counts, neutrophil counts, interleukin (IL-6) levels and fever. The cosmetic outcome was assessed on the basis of a breast evaluation by the medical staff and the patient's subjective satisfaction. RESULTS: In both groups, serious postoperative complications were absent. No significant differences were observed in the leukocyte counts, neutrophil counts, IL-6 level or fever between the groups. An evaluation of the cosmetic outcomes by the staff showed a more favorable breast size, breast shape and scar condition in the endoscopic group. A significantly higher level of patient satisfaction was also observed in the endoscopic group. Postoperative local recurrence was absent. CONCLUSIONS: The endoscopic approach showed comparable safety and invasiveness, and provided better postoperative cosmetic outcomes than direct vision surgery. Our results suggest that endoscopic breast-conserving surgery is a potentially useful surgical method for the treatment of breast cancer.

RESUMO

Despite the good responses of patients (pts) with stage III breast cancer to neoadjuvant chemotherapy (NAC), most eventually relapse and have a poor prognosis. We investigated the prognostic indicators in pts with stage III breast cancer treated with NAC, using epirubicin and/or docetaxel. A total of 22 women with stage III breast cancer underwent NAC between January 2005 and May 2011. The regimens of NAC comprised ED (epirubicin 60 mg/m2 and docetaxel 60 mg/m2) in 10 cases, FEC (fluorouracil 500 mg/m2, epirubicin 75-100 mg/m2 and cyclophosphamide 500 mg/m2) in 10 cases and EC (epirubicin 60 mg/m2 and cyclophosphamide 600 mg/m2) in two cases. Following four cycles of each regimen, a further four cycles of D (docetaxel 70 mg/m2) were undertaken in nine cases. Subsequent to the completion of NAC and surgery, we assessed the clinicopathological results and performed prognostic analyses. Statistical analyses concerning disease-free survival (DFS) or overall survival (OS) were conducted by a Cox proportional hazard model. The median survival time was 66 months and there were 12 distant metastases and two local recurrences. Multivariate analyses showed the number of metastatic axillary lymph nodes (ALNs) [hazard ratio (HR), 1.079; P=0.023] was correlated with DFS, while the Ki-67 labeling index (HR, 1.109; P=0.042) and the number of meta-static ALNs (HR, 1.087; P=0.023) were correlated with OS. In conclusion, even if pts with stage III breast cancer show good responses to NAC using epirubicin and/or docetaxel, the majority eventually relapse and have a poor prognosis. The Ki-67 labeling index and the number of involved ALNs are suggested as prognostic indicators in stage III breast cancer.

RESUMO

OBJECTIVES: This study was conducted to evaluate the relationship between fluorine-18 fluorodeoxyglucose metabolic parameters [maximum standardized uptake value (SUV(max)), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)] and clinicopathological factors of breast cancer. METHODS: The study comprised 93 patients. A volumetric region of interest was drawn over the abnormal focal uptake of breast cancer. Spearman's rank correlation, the Kruskal-Wallis test, and receiver operating characteristic analysis were used to investigate the relationship between clinicopathological factors and metabolic parameters and determine which metabolic parameters were most highly associated with clinicopathological factors. RESULTS: All parameters had a statistically significant relationship with pathological T stage (p-T stage), pathological N status (p-N status), pathological stage (p-stage), and triple-negative type (TN) (all P values were <0.05). There were statistically significant differences between SUV(max) and TLG in relation to lymphatic invasion, estrogen receptor, and nuclear grade (P<0.05). High MTV showed a tendency toward association with estrogen receptor negativity, but the relation did not reach the level of statistical significance (P=0.056). No statistically significant relationship was observed between MTV and lymphatic invasion or nuclear grade. In the receiver operating characteristic analysis of p-T stage and p-stage, the AUC for TLG was significantly larger than that for SUV(max) (P=0.0003 and 0.048, respectively). There were marginally significant differences between TLG and MTV in relation to p-stage (P=0.058). CONCLUSION: TLG may reflect tumor metabolism for clinicopathological factors of breast cancer better than SUV(max) or MTV.

RESUMO

The forkhead box protein 3 (FOXP3) transcription factor is highly expressed in tumor cells as well as in regulatory T cells (Tregs). It plays a tumor-enhancing role in Tregs and suppresses carcinogenesis as a potent repressor of several oncogenes. The clinical prognostic value of FOXP3 expression has not yet been elucidated. In this study, immunohistochemistry was used to investigate the prognostic significance of FOXP3 expression in tumor cells and tumor-infiltrating lymphocytes (TILs) in breast cancer patients. Of the 100 tumor specimens obtained from primary invasive breast carcinoma, 63 and 57% were evaluated as FOXP3+ tumor cells and as being highly infiltrated by FOXP3+ lymphocytes, respectively. Although FOXP3 expression in tumor cells was of no prognostic significance, FOXP3+ lymphocytes were significantly associated with poor overall survival (OS) (n=98, log-rank test P=0.008). FOXP3 exhibited a heterogeneous subcellular localization in tumor cells (cytoplasm, 31%; nucleus, 26%; both, 6%) and, although cytoplasmic FOXP3 was associated with poor OS (P= 0.058), nuclear FOXP3 demonstrated a significant association with improved OS (P=0.016). Furthermore, when patients were grouped according to their expression of tumor cytoplasmic FOXP3 and lymphocyte FOXP3, there were notable differences in the Kaplan-Meier curves for OS (P<0.001), with a high infiltration of FOXP3+ lymphocytes accompanied by a cytoplasmic FOXP3+ tumor being the most detrimental phenotype. These findings indicated that FOXP3 expression in lymphocytes as well as in tumor cells may be a prognostic marker for breast cancer. FOXP3 in tumor cells may have distinct biological activities and prognostic values according to its localization, which may help establish appropriate cancer treatments.

RESUMO

A 62-year-old woman being treated for chronic hepatitis C and high blood pressure was shown by computed tomography to have tumors in the lateral and medial segments of her liver, and in her right breast. The tumor in the lateral segment of the liver was excised, the tumor in the medial segment of the liver was treated with microwave coagulation therapy, and the breast tumor was treated with simple mastectomy and sentinel lymph-node biopsy. Based on pathological features, the liver tumors were classified as moderately differentiated liver cell carcinoma, and the breast tumor as estrogen receptor-negative, progesterone receptor-negative, and human epidermal growth factor receptor-2-positive ductal carcinoma. Hepatic arterial infusion chemotherapy using fluorouracil and cisplatin with trastuzumab as an adjuvant was administered to treat both cancers simultaneously. Twelve months after the operation, neither of the cancers had relapsed. This case suggests that when the breast cancer is human epidermal growth factor receptor-2-positive, trastuzumab should be administered as adjuvant therapy.

RESUMO

This study examined the efficacy and tolerability of docetaxel(DOC)in combination with epirubicin(EPI)as the first-line treatment for patients with advanced and recurrent breast cancer. A total of 56 female patients with metastatic breast cancer not previously treated for metastatic disease received DOC(60mg/m²)and EPI(60mg/m2)on day 1 every 3 weeks. The patient characteristics included a median age of 53 years. Advanced disease was present in 86% of patients, and recurrent disease was found in 14%; 3 or more metastatic sites had been diagnosed in 38% of patients, and 59% patients were ER+. The median number of courses administered was 6. The median dose intensity was 18. 7mg/m²week for DOC and EPI, and the relative dose intensities were 93. 5%and 93. 3%, respectively. The clinical responses included a complete response in 5%, a partial response in 54%, and stable disease in 33% of patients, with a disease control rate of 92%. The progression-free survival was 78. 3%, and the overall survival was 91. 9% at 1 year. Grade 3/4 toxicities included neutropenia in 82%, leukopenia in 71%, febrile neutropenia in 16%, anorexia in 9%, and anemia in 7%of the patients. Neither congestive heart failure nor toxic death occurred. The D and E combination with doses of 60mg/m2 is an active and generally well-tolerated regimen that can be used as first-line chemotherapy for patients with metastatic breast cancer.

RESUMO

4',5,7-Trihydroxy-3',5'-dimethoxyflavone (Tricin), a naturally occurring flavone, has anti-inflammatory potential and exhibits diverse biological activities including antigrowth activity in several human cancer cell lines and cancer chemopreventive effects in the gastrointestinal tract of mice. The present study aimed to investigate the biological actions of tricin on hepatic stellate cells (HSCs) in vitro, exploring its potential as a treatment of liver fibrosis, since HSC proliferation is closely related to the progression of hepatic fibrogenesis in chronic liver diseases leading to irreversible liver cirrhosis and hepatocellular carcinoma. Tricin inhibited platelet-derived growth factor (PDGF)-BB-induced cell proliferation by blocking cell cycle progression and cell migration in the human HSC line LI90 and culture-activated HSCs. It also reduced the phosphorylation of PDGF receptor ß and the downstream signaling molecules ERK1/2 and Akt, which might be due to its tyrosine kinase inhibitor properties rather than inhibition of the direct binding between PDGF-BB and its receptor. Our findings suggest that tricin might be beneficial in HSC-targeting therapeutic or chemopreventive applications for hepatic fibrosis.

RESUMO

PURPOSE: The aim of this study was to investigate the relation between (99m)Tc-tetrofosmin uptake and extracellular signal-regulated kinase mitogen-activated protein kinase (ERK MAPK) expression in papillary thyroid cancer patients. MATERIALS AND METHODS: Our study population consisted of 14 patients. The histopathological findings for all patients were confirmed by surgery. Patients were administ 740 MBq of (99m)Tc-tetrofosmin. The tumor/background (T/B) ratios in regions of interest (ROIs) were measured at 10 min, 1 h, and 3 h to determine the uptake by papillary cancer. Immunohistopathological staining was performed, and the expression of phospho-ERK MAPK in papillary cancer was investigated. The relation between the expression of phospho-ERK MAPK and the T/B ratio was examined using the Mann-Whitney U-test. RESULTS: (99m)Tc-tetrofosmin uptake was positive in all patients. There was a statistically significant relation between the T/B ratio (at 3 h) and the expression of phospho-ERK MAPK but not with the T/B ratio at 10 min or 1 h: T/B ratio at 10 min (P = 0.32), at 1 h (P = 0.62), and at 3 h (P = 0.0072). CONCLUSION: Our results suggest that the relation between (99m)Tc-tetrofosmin uptake (3 h T/B ratio) may lead us to assume cell proliferation of papillary cancer.

RESUMO

We present a case of a 57-year-old woman with a giant malignant phyllodes tumor (PT) in her right breast, with maximum diameter of 20 cm. The core-needle and excisional biopsy specimens were diagnosed as suspicious for low-grade myofibroblastic sarcoma (LGMS). The subsequent total mastectomy with partial resection of the pectoral muscles showed predominance of stromal hypercellularity without an epithelial component. However, we diagnosed this as a malignant PT because focal areas showed a leaf-like pattern. In the case of large malignant PTs that exhibit stromal predominance, it can be difficult to distinguish between a pure sarcoma and malignant PT. It is important to thoroughly examine multiple sections from the view point of residual epithelial structure in morphological diagnosis.

RESUMO

Purpose. To investigate the correlation of Apperent Diffusion Coefficient (ADC) values in invasive ductal breast carcinomas with detailed histologic features and enhancement ratios on dynamic contrast-enhanced MRI. Methods and Materials. Dynamic MR images and diffusion-weighted images (DWIs) of invasive ductal breast carcinomas were reviewed in 25 (26 lesions) women. In each patient, DWI, T2WI, T1WI, and dynamic images were obtained. The ADC values of the 26 carcinomas were calculated with b-factors of 0 and 1000 s/mm(2) using echoplanar DWI. Correlations of the ADC values were examined on dynamic MRI with enhancement ratios (early to delayed phase: E/D ratio) and detailed histologic findings for each lesion, including cellular density, the size of cancer nests, and architectural features of the stroma (broad, narrow, and delicate) between cancer nests. Results. The mean ADC was 0.915 ± 0.151 × 10(-3) mm(2)/sec. Cellular density was significantly correlated with ADC values (P = .0184) and E/D ratios (P = .0315). The ADC values were also significantly correlated to features of the stroma (broad to narrow, P = .0366). Conclusion. The findings suggest that DWIs reflect the growth patterns of carcinomas, including cellular density and architectural features of the stroma, and E/D ratios may also be closely correlated to cellular density.

RESUMO

A 52-year-old woman underwent modified radical mastectomy and axillary lymph node resection for right breast cancer (stage IIB). Afterwards FEC therapy (5-FU 500 mg/m/2, epirubicin 75 mg/m2, cyclophosphamide 500 mg/m2) x 4, docetaxel therapy (60 mg/m2) x 4 and radiation of the illness side collarbone, upper and lower lymph nodes were enforced for adjuvant therapy after the operation. Furthermore, administration of aromatase inhibitor (anastrozole) and trastuzumab was started due to the postoperative pathological diagnosis of hormone receptor-positive and HER2 (score 3+). This became an urgent hospital admission because of the sudden escape power from impaired consciousness due to the articulation disorders and limb weakness when trastuzumab was administered nine times. It was diagnosed by MRI examination and the cerebrospinal fluid cytology as meningeal carcinomatosis of breast cancer, and she died on the 31st recurrence of disease. A serious relapse may be caused in a case of fast-progressing breast cancer like this while being administered trastuzumab as an adjuvant treatment.

RESUMO

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive human cancers, and novel treatment modalities are required. We investigated the therapeutic potential of the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo2L) in combination with the proteasome inhibitor bortezomib (Velcade) on human ESCC cell lines. Bortezomib enhanced the susceptibility to TRAIL in 12 of the 15 ESCC cell lines tested, although most showed low sensitivity to TRAIL as a single agent. The enhancement of TRAIL-induced apoptosis by bortezomib was caspase dependent. Increased processing of caspase-8 often accompanied enhancement of TRAIL-induced apoptosis by bortezomib. However, the increased cell surface expression of death receptors observed on bortezomib treatment did not seem to be crucial for this effect. For some ESCC, bortezomib treatment resulted in a more efficient recruitment of caspase-8 and the Fas-associated death domain to the death-inducing signaling complex. Additional downregulation of the cellular FLICE-inhibitory protein long isoform [c-FLIP(L)] could cooperate in the activation of the extrinsic pathway in some cases. For other ESCC, the crucial effect of bortezomib treatment seemed to be increased signaling via the intrinsic apoptotic pathway on subsequent exposure to TRAIL. Thus, bortezomib could sensitize ESCC to TRAIL apoptosis by multiple molecular mechanisms of action. Therefore, the combination of bortezomib and TRAIL might be a novel therapeutic strategy for ESCC patients who fail to respond to standard chemoradiotherapy that predominantly targets the mitochondrial apoptotic pathway.

RESUMO

We treated a patient with a pseudoaneurysm caused by core needle biopsy (CNB), in which both the cancer and the aneurysm were excised by breast conservation therapy. A 51-year-old woman attended a local hospital because of a 25-mm mass in the upper outer quadrant of the right breast. CNB was performed, and brisk bleeding occurred at the biopsy site. Immediate hemostasis was achieved with direct manual compression. CNB detected fatty tissue, and a diagnosis could not be made. When she presented at our hospital 6 weeks later, there was a 25-mm pulsating mass at the biopsy site. Color-flow Doppler US and dynamic MRI showed a breast tumor and pseudoaneurysm formation. For the purpose of diagnosis and treatment of the breast tumor and pseudoaneurysm, lumpectomy of the right breast was performed. Histological diagnosis was papillotubular carcinoma and pseudoaneurysm. Although this condition is relatively rare, it is important to be aware of the possibility of complications, such as pseudoaneurysms, which require treatment.

RESUMO

A 59-year-old woman underwent modified radical mastectomy for left breast cancer 9 years earlier. This time, a chest wall recurrence was found. A chest CT showed a chest wall tumor and lymph node metastases. PET images showed increased uptake in chest wall tumor and lymph nodes. The serum tumor markers have also elevated. Open biopsy of chest wall tumor was performed, and the tumor was diagnosed as invasive ductal carcinoma[ER(-), Pg R (-), HER2 score(0)]. Combination chemotherapy with capecitabine and docetaxel was initiated. After 7 courses of treatment, a marked response has been seen. Capecitabine and docetaxel combination therapy are considered useful for treatment of triple negative recurrent breast cancer.
