RESUMO
Nodular lymphocyte predominant Hodgkin's lymphoma (NLPHL) is a rare subtype of Hodgkin's lymphoma. In this study, we aimed to investigate the clinical features and therapeutic outcomes of patients with NLPHL who were diagnosed at different institutes in Turkey. We retrospectively reviewed the records of the patients diagnosed with NLPHL. Adult patients who were diagnosed after 2005 with histological confirmation were selected for the study. Forty-three patients were included in the study. Median age of patients was 37.5 years (18-70) at the time of diagnosis. About 60.5% patients were diagnosed as stage I and II NLPHL, and remaining 39.5% had stage III and IV disease. Median follow-up was 46 months. During follow-up, none of the patients died. Seven patients relapsed or progressed after initial therapy at a median of 12 months. Five of 7 relapsed/refractory patients (71.4%) were salvaged with chemotherapy only (DHAP, ICE), and the remaining 2 (28.6%) were salvaged with chemoimmunotherapy. All of relapsed/refractory patients were able to achieve complete remission after salvage therapy. Lactate dehydrogenase levels were significantly higher in patients with progressive disease compared with nonprogressive disease. Our study showed an excellent outcome with all patients alive at last contact with a median follow up of 46 months despite a wide range of different therapeutic approaches. All relapsed and refractory patients were successfully salvaged despite a low frequency of patients received immunotherapy in conjunction with chemotherapy. Our results suggest that immunotherapy may be reserved for further relapses.

Biosimilar filgrastim (Leucostim®) was shown to be similar in terms of efficacy and safety in hematopoietic progenitor cell mobilization (HPCM) compared to originator filgrastim (Neupogen®) and lenograstim (Granocyte®) in healthy donors and chemomobilization settings. Here we report our retrospective experience with Leucostim® (n: 43) compared to Neupogen® (n: 71) and Granocyte® (n: 32) in steady-state mobilization of patients presenting with Hodgkin lymphoma, non-Hodgkin lymphoma and multiple myeloma. The median age of patients on Leucostim® (56) arm was significantly higher compared to patients who received Neupogen® (50) and Granocyte® (49) (p: 0.039). Patients who underwent HPCM with Leucostim® received less chemotherapy lines (p: 0.026) and courses (p: 0.046) compared to others. Otherwise the study cohort was homogenous in terms of gender, primary diagnosis and various risk factors for mobilization failure. Mobilization failure was defined as failure to achieve a minimum threshold (10/µL) for peripheral blood CD34+ cell concentration to initiate leukapheresis or 0.5×106/kg, 0.8×106/kg and 2×106/kg CD34+ cells in first, second and fourth days of apheresis, respectively. The study groups were similar in terms of median number of CD34+ progenitor cell yield (×106/kg) (Neupogen®: 6.18, Granocyte®: 6.2 and Leucostim®: 6.2) (p: 0.959) and median number of leukapheresis sessions (p: 0.615). The treatment arms were also similar in terms of mobilization failure (Neupogen® 11.3% - Granocyte® 21.9% - Leucostim® 16.3%; p: 0.366). No patient experienced any severe adverse effect during HPCM. Leucostim® is equally effective and safe in HPCM compared to originator G-CSF (Neupogen®) and lenograstim (Granocyte®) in steady-state HPCM setting.

PURPOSE: HER2-amplified breast cancer (BC) has a poor prognosis. The combination of trastuzumab with chemotherapy in the adjuvant setting decreases recurrence and improves overall survival in HER2-positive BC. However, the role of adjuvant treatment in patients with HER2-amplified small BC without lymph node involvement is still under debate. The purpose of this study was to investigate the safety of adjuvant paclitaxel and trastuzumab (APT) in this group of patients. METHODS: A total of 87 operated early BC patients without lymph node involvement (N0) were treated with APT for 12 weeks followed by trastuzumab alone for a total of 9 months. Clinicopathological features and adverse events were analyzed. RESULTS: The median patient age was 50 years (range 28- 82), and 51% of them were postmenopausal. The median tumor diameter was 2.4 cm (range 0.5-6), with 51% of the patients having tumor size between 2 and 3 cm. Eighty-one percent of patients had invasive ductal carcinoma (IDC), and 64% had grade 3 tumors. Adjuvant hormone therapy and adjuvant radiotherapy were administered to 65 and 54% of patients, respectively. At a median follow up of 13 months (range 6-38), one patient (1.1%, 95% CI 0-3.4) experienced an asymptomatic decrease in left ventricular ejection fraction (LVEF) and 3 patients (3.4%, 95% CI 0-6.9) experienced grade 3 neuropathy. CONCLUSIONS: APT appears to be a safe combination in early-stage, HER2-amplified and node-negative BC.

PURPOSE: The clinical significance of synchronous bilateral breast cancer (SBBC) is unclear and its influence on prognosis is controversial. Our study objective was to determine the epidemiological features, tumor characteristics, and prognosis of SBBC in comparison with those of unilateral breast cancer (UBC). METHODS: A total of 3675 breast cancer patients diagnosed and treated between 2000 and 2014 were evaluated. Of these patients, 132 (3.6%) had bilateral breast cancer, including 55 patients (1.5%) with SBBC and 77 (2.1%) with metachronous bilateral breast cancer (MBBC). The patient demographic characteristics, including survival data and clinicopathological tumor characteristics, were obtained from medical charts and compared between the patients with SBBC and those with UBC. RESULTS: The median age in the SBBC group was 51 years (range 32-77). The mastectomy rate was higher in the SBBC group (72.7%) than in the UBC group (66.6%) (p=0.08). In both the SBBC and UBC groups, the baseline clinicopathological features and the history of treatment with radiotherapy and chemotherapy were similar. Infiltrating ductal carcinoma was the most common histology in both groups. Lobular histology was more frequent in the SBBC group (36.3%) than in the UBC group (17.1%; p<0.001). Stage IV disease at initial presentation was more frequent in the SBBC group than in the UBC group (34.5 vs 8.7%, p<0.001). The 5-year disease-free survival (DFS) rates were 90% and 82% in the SBBC and UBC groups, respectively (p=0.99). The 5-year overall survival (OS) rates were 83% and 88%, respectively (p=0.357). The multivariate Cox regression analysis, including stage, hormone receptor status, grade, and SBBC, revealed that the presence of SBBC was not associated with OS (hazard ratio 0.929; 95% confidence interval, 0.455-0.1894, p=0.839). CONCLUSION: Despite the differences in histology, initial stage, and other characteristics, the prognoses of UBC and SBBC were similar.

PURPOSE: It is well-known that tumor phenotype may change during the progression of breast cancer (BC). The purpose in this study was to compare the discordance in estrogen receptor (ER), progesterone receptor (PgR) and human epidermal growth factor receptor 2 (HER2) between primary and recurrent/metastatic lesions (RML) and also to evaluate the prognostic significance of change in tumor phenotype on survival in patients with metastatic BC. METHODS: The medical records of 6638 patients with BC from two breast centers treated between 1992 and 2015 were retrospectively analyzed. Of the 6638 patients, 549 cases in whom recurrence was histologically proven by biopsy or by surgical resection were enrolled into this study. RESULTS: Our presentation 13.5% of the patients had metastatic disease. Biopsy on recurrence was obtained from distant metastasis sites in 250 (63.6%) patients or from locoregional soft tissues/lymph-nodes in 143 (36.4%). Receptor discordance in ER, PgR and HER2 expressions between primary and RML were 27.2% (p=0.32), 38.6% (p<0.001) and 14.4% (p=0.007), respectively. Subsequent gain of ER and PgR showed significantly higher overall survival (OS) and post-recurrence survival (PRS) compared to the corresponding concordant-negative patients (119 vs 57 months, p=0.001 and 56 vs 31 months, p=0.03 for ER, 148 vs 58 months, p=0.003 and 64 vs 31 months, p=0.01 for PgR, respectively), hormone receptor (HR) loss was associated with worse OS. Similarly, HER2-loss cases experienced poorer PRS and OS outcomes, compared with those having stable HER2 expression (median 26 vs 60 months, p=0.009 for PRS and median 60 vs 111 months, p=0.06 for OS, respectively). CONCLUSION: This study confirmed the receptor discordance in ER/PgR and HER2 receptor expressions between primary and RML in patients with metastatic BC. As the loss of receptor expression is the most responsible factor for the discordance, treatments of recurrent/metastatic tumors should be individualized on the basis of molecular and genomic properties.

INTRODUCTION: In lymph node-negative, hormone-positive, and Her2-negative breast cancer patients, the benefits of adding adjuvant chemotherapy to hormonal therapy continue to be debated, especially for low to intermediate grade and small tumors. METHODS: Excluding patients with T4 disease, we retrospectively reviewed the records of patients with long-term follow-up at our center between 2003 and 2014. Among node-negative, hormone-positive and HER2-negative breast cancer patients, we compared two groups of patients: those given both chemotherapy (doxorubicin+cyclophosphamide) and hormonotherapy, and those prescribed hormonotherapy alone. The primary endpoints were progression-free (PFS) and overall survival (OS). RESULTS: Overall, no difference was observed between these two treatment groups in either DFS or OS. However, for both outcomes, there was a trend towards improved DFS and OS favoring the hormone-only group. CONCLUSIONS: In selected subgroups of breast cancer patients, administering adjuvant hormonal therapy alone seems to be at least as good if not better than combining hormonotherapy and chemotherapy.

PURPOSE: To compare the effectiveness of adjuvant chemotherapy regimens in triple negative breast cancer (TNBC) for which no protocol has been determined to be treatment of choice. METHODS: In this single-center retrospective trial, we analyzed the adjuvant regimens of 164 TNBC patients among 3253 breast cancer patient records. Adjuvant TAC (docetaxel, doxorubicin, cyclophosphamide), CAF (cyclophosphamide, doxorubicin, 5fluorouracil), and AC-T (doxorubicin, cyclophosphamide followed by docetaxel) regimens were compared in terms of disease free survival (DFS) and overall survival (OS). RESULTS: In terms of both DFS and OS TAC was significantly superior to AC-T in node positive TNBC. When node negative and positive patients were analyzed together, TAC was still significantly superior to AC-T in terms of DFS and OS. There was a trend favoring CAF over AC-T, however, it was only significant in terms of OS when all node negative and positive TNBC patients were incorporated together. CONCLUSION: In the adjuvant setting, especially in node positive patients, TAC should be the treatment of choice in TNBC patients. CAF is probably better than AC-T in TNBC.

PURPOSE: The purpose of this study was to investigate the frequency and prognosis of inflammatory breast cancer (IBC) according to molecular subtypes. METHODS: Demographic data were examined for 78 patients diagnosed with IBC among breast cancer patients monitored in our clinic. Patients were staged according to the 2010 AJCC guidelines. Physical examination and radiographic findings classified on the basis of Response Evaluation Criteria in Solid Tumors (RECIST) guidelines were employed in the evaluation of clinical response to systemic therapy. Subtype analysis was performed in patients with IBC and subtypes were compared. Patients were divided on the basis of metastatic or non metastatic status and survival analysis was performed on the basis of molecular subtypes. RESULTS: Distribution analysis of molecular subtypes revealed a lower incidence of luminal A and a higher incidence of both HER 2 (+) and triple negative breast cancer in IBC. Molecular subtypes had no effect on survival in the non metastatic (p=0.61) and metastatic patient group (p=0.08). CONCLUSION: This study showed that IBC frequency is higher in HER2 overexpressing and triple negative subtypes. No survival differences were noticed in relation to molecular subtypes in IBC patients.

OBJECTIVES: This study aims to investigate the prevalence of systemic rheumatic diseases (SRDs) among patients with breast cancer (BC) and to identify the clinicopathological characteristics of these patients. PATIENTS AND METHODS: A total of 3,744 female patients with BC (mean age 49±11.7 years; range, 18 to 92 years) followed in Hacettepe University Faculty of Medicine, Medical Oncology Department between January 2006 and December 2015 were retrospectively assessed. Patients with or without SRD were compared in terms of clinicopathological features including age, menopausal state, smoking status, Body Mass Index (BMI), age of menarche, age at first labor, and number of children. The groups were also evaluated regarding tumor grade, stage, estrogen receptor and progesterone receptor expression, human epidermal growth factor receptor 2 overexpression, and survival. RESULTS: Of the patients analyzed, 68 (1.81%) had concomitant SRD. Among these patients, 33 (48.6%) had rheumatoid arthritis, eight (11.8%) had familial Mediterranean fever, eight (11.8%) had Behçet's disease, four (5.8%) had Sjögren's syndrome, four (5.8%) had systemic lupus erythematosus, six (8.8%) had ankylosing spondylitis, three (4.4%) had systemic sclerosis, one (1.4%) had polymyositis, and one (1.4%) had temporal arteritis. The groups with or without SRDs were similar in terms of age, smoking status, BMI, menopausal state, breast feeding duration, age at menarche and first birth. Stage 1 and 2 BC was more prevalent in SRD patients (74.6% vs. 64.5%, p=0.018). The rate to receive chemotherapy was significantly lower in patients with SRD. However, there was no significant difference in five-year overall survival rates between patients with or without SRD. CONCLUSION: Among patients with BC, 1.81% had concomitant SRD. These patients were diagnosed at early stages and given chemotherapy less frequently. However, they had similar survival rates compared to those without SRDs.
